Definitions
- the present patent application concerns a lower leg supporting and knee protecting device. More specifically the present patent application relates to a lower leg supporting and knee protecting device, which when used reduces strain on the user's knees and ankles, in accordance with the claims.
- knee pads have been developed to remedy the above problems. Even if several of these partially solve the problem of protecting the knee, there are significant flaws in their designs.
- a major problem with current knee pads is that they do not provide adequate support for both knees and legs together. Standing on your knees with current knee pads means no relief for the knees from the weight of the body, which in turn wears unnecessarily on the different parts of the knee.
- a better distribution of body weight, when a person has to work on their knees, is necessary to reduce fatigue, discomfort and repetitive strain injuries that may lead to health problems such as for example osteoarthritis.
- knee pads are not designed to provide assistance and support when a person has to walk (crawl) on their knees, as is usual during floor work, piping and the like. This also leads to problems with fatigue, discomfort and strain injuries in the legs. Furthermore, today's knee pads, when using these, are plagued by the problem of them moving along the user's leg. For example, the pads glide easily out of their position when the user changes position between standing on their knees and feet as well as during normal walking in the working area.
- Knee pad devices are already known in many different varieties.
- U.S. Pat. No. 2,484,494 describes a variant of a device which allows for reduced strain on the user's knee in connection with work on the floor and the like.
- the design differs greatly from the design of the present invention. For example, it is not possible to vary the position of the user's legs in association with use of the design.
- the design is also not particularly suitable for use during flooring.
- U.S. Pat. No. 6,415,441 describes a variant of a knee pad device.
- the knee pad device allows for the user's knee, to some extent, to be relieved of strain when the device is used.
- the design does not however relieve the user's ankle from strain when using the design according to the patent document.
- U.S. Pat. No. 6,637,034 describes a type of a protective device for the knees.
- the design has a number of flaws which are solved by the design in accordance with the present patent application. For example, it is not possible to vary the position of the user's legs in conjunction with the use of the design.
- U.S. Pat. No. 64,338,754 also describes a variant of a protective device for the knees. Even this design has a number of flaws which are solved by the design in accordance with the present patent application. For example, it is not possible to vary the position of the user's legs in conjunction with the use of the design.
- U.S. Pat. No. 1,666,846 shows a variant of a knee pad.
- the device is intended for use while working when kneeling.
- the knee pad may by definition be said to constitute a lower leg supportive knee pad device, comprising a first and a second contact surface, which is intended to be connected to a user's legs.
- U.S. Pat. No. 1,666,846 differs to a large extent from the design according to the present patent application.
- the knee pad in accordance with U.S. Pat. No. 1,666,846 places strain on the user's kneecap during the whole time that design is used (in conjunction with kneeling work).
- the design thus lacks the ability to switch between a first operational mode and a second operational mode whereby a reduced strain on the user's knees, ankles and toes is achieved especially in the second operational mode.
- the design according to its description is not nearly as beneficial to the user's knees, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- U.S. Pat. No. 1,480,374 describes a variant of a knee pad which includes an angle between a second contact plane and the contact area of a shin (on the inside of the knee pad) which is arranged to be adjustable with at least one adjusting device.
- This design differs greatly from the design in accordance with the present patent application.
- the design strains the knee during the whole time the design is used (for kneeling work).
- the design thus lacks the ability to switch between a first operational mode and a second operational mode where a relief of strain on the user's knees, ankles and toes is achieved especially in the second operational mode.
- the design according to its description is not nearly as beneficial to the user's knees, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- U.S. Pat. No. 6,256,787 shows a knee pad which includes an angle in the range of 140 to 165 degrees between its two contact planes.
- the design has some support against the shin.
- the design results in no relief of strain on the user's knee when using the knee pad.
- the design also incurs a great strain from its buckle (tensioner) against the user's calf when the user leans forward.
- the design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's knees, ankles and toes is achieved especially in the second operational mode.
- the design according to its description is not nearly as beneficial to the user's knees, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- U.S. Pat. No. 6,427,239 describes a variant of a knee pad.
- the knee pad's design differs widely from the design according to the present patent application.
- the design in accordance with its description has the disadvantage of straining the kneecap at all times when the user stretches forward.
- the design lacks therefore the above mentioned second operational mode in which the user's knee and ankle receives reduced strain.
- the design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's kneecaps, ankles and toes is achieved especially in the second operational mode.
- the design according to its description is not nearly as beneficial to the user's kneecaps, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- GB172823 describes a variant of a protective device for use in connection with playing or practicing Cricket.
- the design is only relevant to consider in the respect that it is comprised of a knee pad with inflatable bodies.
- the design in accordance with its description differs to a very large extent in relation to the present patent application.
- the design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's kneecaps, ankles and toes is achieved especially in the second operational mode.
- the design according to its description is not nearly as beneficial to the user's kneecaps, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- U.S. Pat. No. 2,124,158 describes a variant of a knee pad.
- the design has the disadvantage that it strains the knee during the whole time that it is used.
- the design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's kneecaps, ankles and toes is achieved especially in the second operational mode.
- the design according to its description is not nearly as beneficial to the user's kneecaps, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- U.S. Pat. No. 1,117,268 is described a variant of a knee pad. Even this knee pad differs widely from the design according to the present patent application.
- the design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's kneecaps, ankles and toes is achieved especially in the second operational mode.
- the design according to its description is not nearly as beneficial to the user's kneecaps, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- US2007157356A1 describes a variant of pants (trousers) with integrated knee pads.
- the technology described in US2007157356A1 differs greatly from the design in accordance with the present patent application.
- the design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's kneecaps, ankles and toes is achieved especially in the second operational mode.
- the design according to its description is not nearly as beneficial to the user's kneecaps, ankles and toes, as the design in accordance with the lower leg supporting and knee protection device in accordance with the present patent application.
- FIG. 1 shows schematically a lower leg supporting and knee protecting device which is connected to a user's leg in accordance with a first embodiment of the present invention.
- FIG. 2 shows the lower leg supporting and knee protecting device being used by a user where the lower leg supporting and knee protecting device is in a second operational mode.

- FIG. 6A shows an alternate embodiment of the lower leg supporting and knee protecting device equipped with an adjustment device.
- FIG. 6B shows an alternate embodiment of an adjustment device for a lower leg supporting and knee protecting device.
- FIGS. 7A and 7B show how the lower leg supporting and knee protecting device may be used in at least two different modes of operation.
- FIGS. 8A and 8B show how the knee, ankle and toes are put under strain during kneeling without the use of any type of supporting and protecting device.
- the knee pad device 1 may be comprised of a separate unit which is intended to be connected to the user's 2 legs 3 .
- the knee pad device 1 may be connected to the leg on the outside of a garment 4 such as a pair of pants (trousers) 5 or the like.
- the knee pad device 1 may be connected to or integrated into a garment 4 such as a pair of trousers (pants) or the like.
- the knee pad device 1 is preferably designed to be used in pairs in which one knee pad is connected to the user's first leg and the other is connected to the user's second leg.
- the knee pad device 1 includes at least one interior and one exterior side.
- the interior is the side of the knee pad that during use of the knee pad is placed against the user's leg such as the shin.
- the exterior is made up of the side of the knee pad device 1 that during use of the knee pad is intended to provide a supporting surface against the floor.
- the shape of the knee pad device's 1 interior is preferably completely or partially adapted to the shape of the user's lower leg.
- the knee pad device 1 includes at least one supporting underlay 6 , at least one padding 7 and at least one connection device 8 with which the knee pad is connected to the user's leg 3 .
- the connection device 8 is used to connect the knee pad 1 to a garment 4 or similar.
- the connection device 8 may be used to connect the knee pad 1 to both the user's leg 2 and to a garment 4 .
- the supporting underlay 6 includes at least one covering (sheath or similar) 9 which is connected to and partially surrounds at least one distance spacer 10 .
- the covering 9 consists preferably of a relatively hard and impact-resistant material such as some form of polymeric material, materials of metal such as aluminum, carbon fiber or other suitable material for the purpose.
- the covering 9 may also be made from a combination of several different types of materials.
- the distance spacer's 10 main function is to provide a distance between the floor and the user's legs.
- the distance spacer 10 is preferably of “cell foam” or another for the purpose suitable material.
- the supporting underlay's 6 contact surface against the underlying surface is divided into at least one first contact surface 11 and at least one second contact surface 12 .
- the first contact surface 11 is positioned in the upper section of the supporting underlay 6 and the second contact surface 12 is preferably positioned in the lower section of the supporting underlay.
- Contact surfaces 11 and 12 may in turn be divided into at least one first sub-section and into at least one second sub-section. Alternatively, each respective contact surface may consist of several sub-sections.
- the first contact surface 11 is comprised of at least one first contact plane 13 and the second contact surface 12 is comprised of at least one second contact plane 14 which is divided into at least one first sub-surface 15 and at least one second sub-surface 16 .
- the first contact plane 13 is preferably angled according to angle V relative to the other contact plane 14 .
- the angle V between the first contact plane 13 and the second contact plane 14 is in a range from 91 to 179 degrees.
- the angle V lies between the first contact plane 13 and the second contact plane 14 within the range of 140 to 165 degrees.
- the angled design allows the knee pad to be used in two positions, which are hereinafter referred to as the first operational mode and the second operational mode. In the first operational mode, as shown in FIG.
- all or part of the contact plane 13 lies against the underlying surface.
- all or part of the contact plane 14 lies against the underlying surface. The user may, while working in the kneeling position, switch between these modes of operation during the work process.
- the thickness of the knee pad device 1 is selected to allows this relief (reduced strain).
- the thickness of the kneepad may vary greatly within the scope of the present invention's concept.
- the length of the knee pad may also therefore vary greatly within the scope of the present invention's concept.
- the length of the knee pad is primarily adapted according to the user's lower leg (shin) length.
- the angle V2 between the second contact surface 12 and the inside of the surface against the shin is of great importance.
- the angle is designated by the user's shin length.
- the angle between the second contact surface 12 and the inside of the surface against the shin is essentially in a range from 0 to 15 degrees.
- the angle between the second contact surface 12 and the surface against the shin lies within the range of 1 to 5 degrees. In another preferred embodiment the angle between the second contact surface 12 and the surface against the shin lies within the range of 1 to 15 degrees.
- the present knee pad allows working while kneeling to be carried out in at least two modes of operation, with the knee pad in two distinct positions.
- the first operational mode the user often extends forward and rests on the one hand and performs work with the other hand.
- this operational mode the user's knees are strained to a large extent by the body's weight, but part of the body weight is carried by the supporting hand against the underlying surface.

The lower leg supporting and knee protecting device (1) includes at least one underlay supporting element (6), at least one padding (7) and at least one connection device (8). Unique to the present lower leg supporting and knee protecting device (1) is that the underlay supporting element (6) includes at least one contact surface (11) which allows the device to be used in a first operational mode and that a second contact surface (12) allows the device to be used in a second operational mode.
Description
- The present patent application concerns a lower leg supporting and knee protecting device. More specifically the present patent application relates to a lower leg supporting and knee protecting device, which when used reduces strain on the user's knees and ankles, in accordance with the claims.
- For many types of jobs, there is a need to work while kneeling. Such work exists, for example in conjunction with floor carpeting, floor covering and similar efforts, especially in the construction industry, where the job at hand is on or in proximity to the floor or in confined spaces that do not allow other working postures. Kneeling for long periods is uncomfortable for most people and causes fatigue and physical discomfort because kneeling is not a natural or ergonomic position for human beings during prolonged periods. Not only is kneeling a problem, even crawling (moving, walking) on the knees, is sometimes necessary in certain work situations and this is also very difficult for people. The human body has not evolved in an optimal way for this type of movement. For example, a large number of floor layers report work injuries in their knees each year. In a report on the problem, it has been concluded that an average floor layer moves approximately seventy kilometers per year on their knees.
- It is a serious problem to use the body's joints in extreme positions. For example, when working on their knees, the person who is kneeling most often chooses to twist their ankle joint to its most extended position. When joints are extended to extreme positions, they are exposed to substantial forces and thus the risk of injury increases.
- The problems caused by working while on the knees also means that many professionals avoid kneeling or moving while on their knees and instead bend their backs in a manner that causes unfavorable strain on the back.
- A wide variety of knee pads have been developed to remedy the above problems. Even if several of these partially solve the problem of protecting the knee, there are significant flaws in their designs. A major problem with current knee pads is that they do not provide adequate support for both knees and legs together. Standing on your knees with current knee pads means no relief for the knees from the weight of the body, which in turn wears unnecessarily on the different parts of the knee. A better distribution of body weight, when a person has to work on their knees, is necessary to reduce fatigue, discomfort and repetitive strain injuries that may lead to health problems such as for example osteoarthritis.
- Another problem with contemporary knee pads is that they are not designed to provide assistance and support when a person has to walk (crawl) on their knees, as is usual during floor work, piping and the like. This also leads to problems with fatigue, discomfort and strain injuries in the legs. Furthermore, today's knee pads, when using these, are plagued by the problem of them moving along the user's leg. For example, the pads glide easily out of their position when the user changes position between standing on their knees and feet as well as during normal walking in the working area.
- Knee pad devices are already known in many different varieties. For example U.S. Pat. No. 2,484,494 describes a variant of a device which allows for reduced strain on the user's knee in connection with work on the floor and the like. The design differs greatly from the design of the present invention. For example, it is not possible to vary the position of the user's legs in association with use of the design. The design is also not particularly suitable for use during flooring.
- Even U.S. Pat. No. 6,415,441 describes a variant of a knee pad device. The knee pad device, according to patent document, allows for the user's knee, to some extent, to be relieved of strain when the device is used. The design does not however relieve the user's ankle from strain when using the design according to the patent document. Furthermore, it is not possible to use the design in both a working mode and a rest mode in accordance with the present invention.
- Even U.S. Pat. No. 6,637,034 describes a type of a protective device for the knees. The design has a number of flaws which are solved by the design in accordance with the present patent application. For example, it is not possible to vary the position of the user's legs in conjunction with the use of the design.
- U.S. Pat. No. 64,338,754 also describes a variant of a protective device for the knees. Even this design has a number of flaws which are solved by the design in accordance with the present patent application. For example, it is not possible to vary the position of the user's legs in conjunction with the use of the design.
- U.S. Pat. No. 1,666,846 shows a variant of a knee pad. The device is intended for use while working when kneeling. The knee pad may by definition be said to constitute a lower leg supportive knee pad device, comprising a first and a second contact surface, which is intended to be connected to a user's legs. In all other ways the design in accordance with patent document U.S. Pat. No. 1,666,846 differs to a large extent from the design according to the present patent application. For example, the knee pad in accordance with U.S. Pat. No. 1,666,846 places strain on the user's kneecap during the whole time that design is used (in conjunction with kneeling work). The design thus lacks the ability to switch between a first operational mode and a second operational mode whereby a reduced strain on the user's knees, ankles and toes is achieved especially in the second operational mode. The design according to its description is not nearly as beneficial to the user's knees, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- U.S. Pat. No. 1,480,374 describes a variant of a knee pad which includes an angle between a second contact plane and the contact area of a shin (on the inside of the knee pad) which is arranged to be adjustable with at least one adjusting device. This design differs greatly from the design in accordance with the present patent application. For example, the design strains the knee during the whole time the design is used (for kneeling work). The design thus lacks the ability to switch between a first operational mode and a second operational mode where a relief of strain on the user's knees, ankles and toes is achieved especially in the second operational mode. The design according to its description is not nearly as beneficial to the user's knees, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- U.S. Pat. No. 6,256,787 shows a knee pad which includes an angle in the range of 140 to 165 degrees between its two contact planes. The design has some support against the shin. The design results in no relief of strain on the user's knee when using the knee pad. The design also incurs a great strain from its buckle (tensioner) against the user's calf when the user leans forward. The design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's knees, ankles and toes is achieved especially in the second operational mode. The design according to its description is not nearly as beneficial to the user's knees, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- U.S. Pat. No. 6,427,239 describes a variant of a knee pad. The knee pad's design differs widely from the design according to the present patent application. For example, the design in accordance with its description has the disadvantage of straining the kneecap at all times when the user stretches forward. The design lacks therefore the above mentioned second operational mode in which the user's knee and ankle receives reduced strain. The design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's kneecaps, ankles and toes is achieved especially in the second operational mode. The design according to its description is not nearly as beneficial to the user's kneecaps, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- GB172823 describes a variant of a protective device for use in connection with playing or practicing Cricket. The design is only relevant to consider in the respect that it is comprised of a knee pad with inflatable bodies. In all other ways, the design in accordance with its description differs to a very large extent in relation to the present patent application. The design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's kneecaps, ankles and toes is achieved especially in the second operational mode. The design according to its description is not nearly as beneficial to the user's kneecaps, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- U.S. Pat. No. 2,124,158 describes a variant of a knee pad. The design has the disadvantage that it strains the knee during the whole time that it is used. The design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's kneecaps, ankles and toes is achieved especially in the second operational mode. The design according to its description is not nearly as beneficial to the user's kneecaps, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- Even in the stated document U.S. Pat. No. 1,117,268 is described a variant of a knee pad. Even this knee pad differs widely from the design according to the present patent application. The design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's kneecaps, ankles and toes is achieved especially in the second operational mode. The design according to its description is not nearly as beneficial to the user's kneecaps, ankles and toes, as the design in accordance with the lower leg supporting and knee protecting device in accordance with the present patent application.
- US2007157356A1 describes a variant of pants (trousers) with integrated knee pads. The technology described in US2007157356A1 differs greatly from the design in accordance with the present patent application. The design also lacks the ability to switch between a first operational mode and a second operational mode whereby a relief of strain on the user's kneecaps, ankles and toes is achieved especially in the second operational mode. The design according to its description is not nearly as beneficial to the user's kneecaps, ankles and toes, as the design in accordance with the lower leg supporting and knee protection device in accordance with the present patent application.
- None of the patent documents mentioned above describes a lower leg supporting and knee protecting device in accordance with the device according to the present patent application. There is currently no corresponding design (knee pads or the like) that includes a feature where the user in a similar manner may vary posture between a first and a second operational mode in a manner similar to the design in accordance with the present patent application.

knee protecting device 1 in accordance with the present patent application is shown. The lower leg supporting and knee protecting device is referred to hereafter in the text with the shorter term of “knee pad” or “knee pad device”. Theknee pad device 1 according to the present invention may be comprised of a separate unit which is intended to be connected to the user's 2legs 3. Preferably, theknee pad device 1 may be connected to the leg on the outside of a garment 4 such as a pair of pants (trousers) 5 or the like. In alternative embodiments, theknee pad device 1 may be connected to or integrated into a garment 4 such as a pair of trousers (pants) or the like. Theknee pad device 1 is preferably designed to be used in pairs in which one knee pad is connected to the user's first leg and the other is connected to the user's second leg. - The
knee pad device 1 includes at least one interior and one exterior side. The interior is the side of the knee pad that during use of the knee pad is placed against the user's leg such as the shin. The exterior is made up of the side of theknee pad device 1 that during use of the knee pad is intended to provide a supporting surface against the floor. The shape of the knee pad device's 1 interior, is preferably completely or partially adapted to the shape of the user's lower leg. - The
knee pad device 1 includes at least one supportingunderlay 6, at least onepadding 7 and at least oneconnection device 8 with which the knee pad is connected to the user'sleg 3. In alternative embodiments of theknee pad 1 theconnection device 8 is used to connect theknee pad 1 to a garment 4 or similar. Alternatively, theconnection device 8 may be used to connect theknee pad 1 to both the user'sleg 2 and to a garment 4. - In the first embodiment of the present knee pad, which is schematically shown in
FIG. 1-3 , the supportingunderlay 6 includes at least one covering (sheath or similar) 9 which is connected to and partially surrounds at least onedistance spacer 10. Thecovering 9 consists preferably of a relatively hard and impact-resistant material such as some form of polymeric material, materials of metal such as aluminum, carbon fiber or other suitable material for the purpose. Thecovering 9 may also be made from a combination of several different types of materials. The distance spacer's 10 main function is to provide a distance between the floor and the user's legs. Thedistance spacer 10 is preferably of “cell foam” or another for the purpose suitable material. - In the first embodiment of the present invention, the supporting underlay's 6 contact surface against the underlying surface (such as flooring or the like) is divided into at least one
first contact surface 11 and at least onesecond contact surface 12. Thefirst contact surface 11 is positioned in the upper section of the supportingunderlay 6 and thesecond contact surface 12 is preferably positioned in the lower section of the supporting underlay. Contact surfaces 11 and 12 may in turn be divided into at least one first sub-section and into at least one second sub-section. Alternatively, each respective contact surface may consist of several sub-sections. - In the first embodiment, the
first contact surface 11 is comprised of at least one first contact plane 13 and thesecond contact surface 12 is comprised of at least onesecond contact plane 14 which is divided into at least one first sub-surface 15 and at least one second sub-surface 16. In the shown embodiment, the first contact plane 13 is preferably angled according to angle V relative to theother contact plane 14. The angle V between the first contact plane 13 and thesecond contact plane 14 is in a range from 91 to 179 degrees. Preferably, the angle V lies between the first contact plane 13 and thesecond contact plane 14 within the range of 140 to 165 degrees. The angled design allows the knee pad to be used in two positions, which are hereinafter referred to as the first operational mode and the second operational mode. In the first operational mode, as shown inFIG. 3 , all or part of the contact plane 13 lies against the underlying surface. In the second operational mode, as shown inFIG. 2 , all or part of thecontact plane 14 lies against the underlying surface. The user may, while working in the kneeling position, switch between these modes of operation during the work process. - In order to reduce (relief) strain on the user's ankle when working kneeling down, according to the second operational mode, the thickness of the
knee pad device 1, that is, thecovering 9, thedistance spacer 10 and thepadding 7, is selected to allows this relief (reduced strain). Depending on the user's body size, such as leg length, the thickness of the kneepad may vary greatly within the scope of the present invention's concept. The length of the knee pad may also therefore vary greatly within the scope of the present invention's concept. The length of the knee pad is primarily adapted according to the user's lower leg (shin) length. - In order to achieve a reduction in strain on the user's ankle in the second operational mode, even the angle V2, between the
second contact surface 12 and the inside of the surface against the shin, is of great importance. The angle is designated by the user's shin length. The angle between thesecond contact surface 12 and the inside of the surface against the shin is essentially in a range from 0 to 15 degrees. Preferably, the angle between thesecond contact surface 12 and the surface against the shin lies within the range of 1 to 5 degrees. In another preferred embodiment the angle between thesecond contact surface 12 and the surface against the shin lies within the range of 1 to 15 degrees. - Unique to the present knee pad is that it allows working while kneeling to be carried out in at least two modes of operation, with the knee pad in two distinct positions. In the first operational mode, the user often extends forward and rests on the one hand and performs work with the other hand. In this operational mode the user's knees are strained to a large extent by the body's weight, but part of the body weight is carried by the supporting hand against the underlying surface. In the second operational mode essentially no strain is put on the user's knee (knees), because body weight is supported by the shin (shins) and to some extent by the user's foot (feet). Thanks to this design, the ankle (ankles) is essentially relieved of strain. The second operational mode, thanks to the design, unburdens the user's knees without the user having to get up. By the user being able during work to switch between the first operational mode and the second operational mode, the user will be able to carry out prolonged work while kneeling without discomfort.
- The
connection device 8 may vary greatly.FIGS. 1 to 3 show a possible variant of theconnection device 8 which includes at least one first connecting body 17, at least one second connecting body 18 and at least one third connecting body 19. The first connecting body 17 and the second connecting body 18 are intended to be used to connect theknee pad 1 to a user's shin. The third connecting body 19 is intended to connect the knee pad to the leg above the user's knee. - The connecting bodies 17, 18 and 19 each include, in the exemplifying embodiment, at least one
first attachment element 20 and at least onesecond attachment element 21.Attachment elements knee pad 1 with a previously known technique. The other end of each strap consists of a free end. The free end of each strap is preferably provided with a coupling body. The coupling bodies may consist of Velcro or other suitable for the purpose coupling bodies. The first attachment element's (strap's) coupling body and the second attachment element's (strap's) coupling body are intended to be connected to each other by the coupling bodies. - In alternative embodiments, it is conceivable that the
connection device 8 is comprised of a sock-like design (not shown in the figures) which extends along parts of the shin and over the knee. In other alternative embodiments, it is also conceivable that another or several other, for the purpose suitable connection devices be used to connect the knee pad to the user's leg. - With reference to
FIG. 4 , a second embodiment of the present knee pad's contact surface (contact surfaces) with the underlying surface is shown. In this embodiment, the first sub-section is comprised of a contact plane and the second sub-section consists of a bent, curved, arched surface. The arched surface allows for a non-incremental variation of the user's position (for example kneeling) in the operational mode. The figure also shows asupport 22, support pillow or the like which is placed between the calf and the thigh. Thesupport 22 allows for the knee (hollow of the knee) to be supported. Furthermore, thesupport 22 increases the angle between the calf and the thigh. - With reference to
FIG. 5 , a third embodiment of the present knee pad's contact surfaces against the underlying surface is shown. In the third embodiment, the surface of the supporting underlay is comprised of a bent, curved or arched surface. The arched surface may be comprise of a cohesive surface or consist of a surface which is divided into two or more sub-sections. The design allows for a non-incremental transition of the user's knee and shin positions in the first and second operational mode. - In alternative embodiments, it is conceivable that the interior be designed to be adjustable with respect to the individual user's legs. This can be done by insertions, inflatable structures or by other malleable (formable) parts.

FIGS. 6A and 6B , alternative embodiments of the knee pad are shown where the angle V2 between the contact plane and the interior of the surface against the shin is arranged to be adjustable with at least one adjusting device 23.FIG. 6A shows an exemplifying embodiment of the adjusting device 23 in which a gradual adjustment of the angle of V2 may be accomplished. The adjusting device 23 according to this embodiment includes a first adjusting body 24 and a second adjusting body 25. The first adjusting body 24 and the second adjusting body 25 may be interconnected with each other in at least two different positions, preferably in several different positions. Each position entails different degrees of the angle V2. -
FIG. 6B shows an embodiment of the adjusting device 23 with which the angle V2 may be non-incrementally adjusted. The adjusting device 23 includes, in this embodiment, a bellow 26 or the like, which to varying degrees may change form by a pressurized medium such as gas, gas mixture or with a liquid or liquid mixture. Pressurization of the bellow 26 or the like is accomplished with at least onepressurizing device 27 or the like. Depending on the level of pressurization in the bellow 26, the angle V2 is adjusted non-incrementally. The exemplified pressurizingdevice 27 is only one conceivable variant of apressurization device 27 that can be used in the present invention. The shownpressurization device 27 may in other embodiments consist of a gas tube (container) with pressurized gas such as CO2 cartridges or other suitable for the purpose pressurization device. - In alternative embodiments, it is conceivable that the
distance spacer 10, thecovering 9 and thepadding 7 may include a function to allow for ventilation through the knee pads. Ventilation may be achieved by thedistance spacer 10, thecovering 9 and thepadding 7 being provided with holes, channels, slits (grooves) or the like through which a flow of air can take place. - Sections of the supporting underlay's 6 contact surface (or contact surfaces) against the underlying surface may, in alternative embodiments, include at least one exchangeable material layer. The material layer or layers are connected with at least one fastener, and preferably one, two or more fasteners to the supporting
underlay 6. The fasteners may consist of Velcro, hooks and loops or other suitable for the purpose fasteners. In alternative embodiments, it is conceivable that the fastener consist of at least one adhesive material layer. - With reference to
FIGS. 7A and 7B , it is shown how the lower leg supporting andknee protecting device 1 in accordance with the present patent application may be used in at least two different modes of operation. The figures show how the strain on the kneecap (knee), ankle and toes varies between the second operational mode and the first operational mode. -
FIG. 7A shows how the first operational mode places a strain on the knee in conjunction with the user leaning forward when working. In the first operational mode the user's knee is placed under strain while the user's ankle and the toes are partially or completely relieved of strain. -
FIG. 7B shows how the second operational mode relieves strain either partially or completely on the user's kneecaps, ankles and toes. This reduction in strain is due to the user's shins resting against the lower leg supporting andknee protection device 1 and that the user's knees do not rest against the supportingunderlay 6. Reduction in strain on the user's knees, ankles and the toes may occur in varying degrees within the scope of the present patent application. Relief (reduction) of strain on the knees, ankles and toes is partially or completely dependent on the lower leg supporting and knee protecting device's 1 thickness (vertical height as shown inFIG. 7B ). - When using the knee pad, it is used in an alternating manner, between a first operational mode and a second operational mode. When using the knee pad during for example a floor layer's or carpet layer's work day, the knee pad is for example used 80% of their time in the second operational mode and 20% of the time in the first operational mode. By alternating between the second and the first operational modes, a significant improvement over the unfavorable strain on the knees, ankles and toes of known designs is achieved.
-
FIG. 8A to 8C show how the knee, ankle and toes are put under strain during kneeling without the use of any supporting and protecting device in comparison with the use of the present invention which inFIGS. 7A and 7B show how the present invention relieves this strain.FIG. 8A to 8C also show how strain is concentrated to small areas (points) on the knee, ankle and toes. - In the detailed description of the present invention, design details may have been omitted which are obvious to persons skilled in the art of the invention's field. Such obvious design details are included to the extent necessary so that the proper and full performance of the present invention is achieved.
- Even if certain preferred embodiments have been described in detail, variations and modifications within the scope of the invention may become apparent for specialists in the field of the invention. All such variants are regarded as falling within the scope of the following claims. In alternative embodiments, it is for example conceivable that the angle between the first contact plane 13 and the
second contact plane 14 are incrementally or non-incrementally adjustable. This adjustability may be achieved by a, for the purpose, suitable earlier know technology. - The present invention achieves a number of advantages. The most obvious is that a substantially improved lower leg supporting and knee protecting device with superior ergonomic qualities is obtained. Another advantage is that the lower leg supporting and knee protecting device may be used for at least one first operational mode and at least one second operational mode which allows the user to manage a prolonged kneeling period during work without discomfort. A further advantage of the present lower leg supporting and knee protecting device is that it may reduce work related health problems such as for example osteoarthritis. A yet further advantage of the present lower leg supporting and knee protecting device is that it is positioned against the user's lower leg and knee in a substantially better way than previously known designs.
