Description
ERGONOMIC SKATE BOOT WITH SHOCK ABSORBER
FIELD OF INVENTION_ This invention relates to in-line roller skates and more Particularly to a shock absorbing mechanism in an in-line roller skate.
to øACKGROUND OF THE INVENTION
Roller skates, since their inception, have been plagued with vibration problems particularly when they are use on rough surfaces, in part~riar outdoor, such as, asphalt roads or oona~ete sidewalks. Attempts have been made to dampen such vibrations by placing cushions between the truck chassis, and the boot.
For instance, cushions covering the entire foot length have been placed deiween the boot and the chassis. In other embodiments, cushions have been placed between the chassis and the ball of the foot and the heel of the foot.
An unfortunate thing about resisting vibrations, is that one loses some control. In over words, the more antNibrational type padding is used, the less control the boot has. One of the drawbacks when using back and front cushions, is that is that the cushions, while damping vibrations, also damp the force and energy 2 5 tn~nsmitted from the foot to the frame. The skater has less contra! than with skate without cushions.
Thus, there is a need in the industry to provide a roller skate with improved anti-vibrations charactecisbcs, but without reduang the control and general 3 0 performance of the skates.
SUBSTITUTE SHEET (RULE 26) SUMMARY OF THE INVENTION
It is thus an object of the invention to provide a roller skate providing simultaneously improved control to the skater and comfort through the reduction of vibration.
As embodied and broadly described herein, the invention provides an in-line roller skate comprising:
-a boot for enclosing a skater's foot and having a front portion substantially corresponding to a toes region of a wearer's foot, and a rear portion substantially corresponding to the heel region of a wearer's foot;
-a lower truck chassis adapted to be supported by a plurality of rotatably mounted in-line wheels defining a rolling plane;
-said chassis being pivotally connected to said rear portion of the boot by a pivot-like member and to said front portion of the boot by a translating connection member, said translating connection member being adapted to provide a translation movement of the boot with relation to the chassis along a given length in a direction substantially normal with relation to said roQing plane;
2 0 -said skate further including a resilient member located between a front portion of the chassis and said front portion of the boot.
Vibrations are thus damped in the most cxitical areas. The connection between the boot and the chassis ensures efficient control of the skates.
In a variant the pivot-like member is comprised of a pivot pin.
In another variant, the pivot-like member is comprised of hinge-like member.
3 0 In another variant, the hinge-like member is of resilient type.
These all provide ease of manufacturing and tow cost.
- WO 99/5b840 PCT/CA98/00443 The resilient member is advantageously comprised of a resilient pad.
The translating connection member is advantageously comprised of an elongated slot, provided in either one of said chassis or said boot, adapted to receive a sliding member, adapted to connect said boot to said chassis. The boot and the chassis are thus well connected, providing enhanced control of the skates. The slot provides one degree of freedom, allowing vibration damping with the use of the res!'tient member.
IO
The roller skate of the invention also preferably comprises a stabil'~zing member, extending from either one of said boot or said chassis to cooperate with a corresponding member, provided on the other of said boot and said chassis, said members being adapted to provide lateral support of the boot with relation to the chassis. This provides improved stability and enhanced control of the skates.
As embodied an broadly described herein, the invention also provides an in-line roller skate comprising a boot with at least one pair of downwardly extending 2 o substantially parallel extensions, more particularly one forward pair, a lower truck chassis adapted to be supported by a plurality of rotatably mounted in-line wheels defining a rolling plane, said chassis including a pair of front substantially elongated slots extending along an axis substantially norma~with relation to said rolling plane, said chassis being connected to a rear portion of the boot by a 2 5 pivot-like member and to said front extensions by a slidable connecting member adapted to move within said slots, said skate further including a resilient member located between a front upper part of the chassis and a front portion of an outer sole of the boot.
3 o tn operation, said boot is adapted to p'nrot about said pivot member relative to said chassis and move upwardly or downwardty relative to the front of said chassis, thereby n~uang vibration by up and down movement which causes decompression and compression of said resilient pad respectively.
Advantageously the boot further comprises a rear pair of dowrnvarclly extending substantially parallel extensions. The pair of rear extensions prefierably includes a pair of co-axial apertures.
The chassis is advantageously connected to said rear extensions.
!n a variant, the chassis includes a pair of co-axial rear apertures; the chassis is 1 o preferably connected to said rear extensions with pivot members provided in said apertures.
The present invention uses a piece of flexible cushion under the front sole of the foot. There is a faced point of attachment betv~en the hell region of the boot and the truck chassis. This fixed point of attachment is, however, pivotal. A
second point of attachment between the front portion of the boot and the chassis has substantially vertical play. The aperture in the chassis (or in the boot if the construction is reversed) is a substantially vertically elongate slot pemlitting a connecting member to move substantially upwardly and downwardly. The front 2 0 interface has a vertical play of a few millimetres. Movement is permitted in one direction, ie, the direction of the flex. Thus, the system permits good control in other directions where stability is important.
The shock absorber of the present invention works virtually only in the places 2 5 where most shocks are felt. This system is particularly adapted to the manoeuvres of a skater who flexes forwarcliy as he skates. tt is more important to keep good control behind with a fixed pivot point and a moveable point in front.
30 Thus, in summary, the pn3sent invention has a pivot attaching the boot to the truck chassis side rails at the rear and a point of attachment of substantially vertical play at the front. The flexible resilient cushion under the ball of the foot is advarttageously between the boot and the tnrck chassis.
Other objects and features of the invention will become apparent by reference to the following description and the drawings.

DETAILED DESCRIPTION OF THE INVENTION
The present invention, as shown in Figures 1 and 2, comprises an in-line roller skate shown basically as 1. The in-line roller skate 1 consists of a boot 2, which is attached to a wheel chassis 3. Rotatably mounted within the side walls of the wheel chassis 3 are a plurality of a aligned wheels 4. Wheels 4 are mounted on axles 5 in a conventional manner.
According to one embodiment of the invention, the boot portion of the skate consists of a partial outer boot and an inner liner. The outer boot may comprise a elastic wrap-around heel support 6, as shown in Figures 1, 2 and 2 0 3. The type of boot illustrated in figures 1 to 9 is an-anged for more comfort, ergonomics and performance. Other types of boots may also be used in accordance with the present invention.
An upper cuff 9, which is pivotally connected to the lower outer boot, provides 2 5 ankle support. Figure 3, shows a pair of rear lower boot extensions 10 and a pair of front lower boot extensions 11 advantageously integrally molded with the lower outer boot. These extensions are conftgured to attach the boot to the truck chassis 3. Preferably, the rear lower boot extensions have indentations 10a adapted to encircle one of the wheel axles 5 to avoid 3 o interference with the axle. The forepart of the truck chassis 3 has a pair of substantially vertically elongate apertures 12 which are adapted to align with apertures 13 in the front lower boot extension 11.
Figures 1 and 2, illustrate the translating connection member 38: for instance, a substantially vertically slidable front connecting pin 34 connects apertures 12 and 13. In the rear of chassis 3, is a pair of apertures 14 adapted to cooperate and align with pivot point apertures 15 located in rear lower boot extensions 10. The position of the apertures 14 andlor 15 may vary depending on the construction and the desired characteristics. Rear pivot pin 33 connects apertures 14 and 15 to pivotally secure the rear lower boot extensions 10 of boot 2 to the chassis while vertically slidable front 2 0 connecting pin 34 connects front lower boot extensions 11 of the boot 2 to the front portion of the chassis 3 at vertically elongate apertures 12. The position of aperture 13 and the position andlor orientation of the aperture 12 may also vary according to the desired construction and characteristics.
As shown more clearly in Figure 3, upper cuff outer boot 9 advantageously contains a buckle aperture 16 and an upper flex pivot aperture 17. This is adapted to cooperate with lower flex pivot aperture 18 found in the lower outer boot. A flex device 19 is adapted to fit within upper flex pivot aperture 17 and lower flex pivot aperture 18.
As shown in more clearly in the upper portion of Figure 3, the liner or inner boot, consists of a rear inner boot 20 equipped with an ankle cushioning pad 20a. The liner also consists of a front inner boot 21. Rear and front inner boots 20 and 21 rest on an inner boot base 22.
The skaters foot is secured in the boot by means of laces 27 which traverse lace holders 28, these being located on a lace support pad 29 which is integrally connected to the front inner boot 21. An upper lace tightener 30 is used to tighten the laces.
Support to the ankle region and the upper cuff is provided by a strap 31 which is adapted to be secured within buckle 32 to tighten the upper cuff outer boot 9.
As shown in Figures 1, 2 and 3, a resilient member, for instance one (or more) elastomeric absorber or pad 35 is placed between the sole of boot 2 and the skate chassis 3 at the front portion thereof to provide resiliency in a substantially vertical direction as the boot 2 pivots in relation to the skate chassis 3 about pivot member 33. The pad could also be made removable. In such a case, a set of pads of different characteristics andlor different materials could be provided. The skater selects the pads according to his skills or type of skating, with more or less damping.
Figures 4 and 5 show other details of this boot embodiment. The outer boot with its various padding elements without liner portions 20, 21 and 22. The tendon cushioning portion 26 and the fifth metatarsal padding 23, are shown.
In Figures 4 and 5 one sees that the upper cuff outer boot 9 is connected to the heel sup~rt lower outer boot 6 by means of flex device 19.
In Figures 6, 6a, 7 and 7a, one views the shock absorber in an uncompressed situation and in a compressed situation. The distance between the bottom of the 2 o boot and the top of the chassis in an uncompressed situation is "X", whereas, in a compressed situation, the distance between the boot and chassis "X'" is smaller.
An arc, through which translating connection member 38, for instance pin 34 (in 2 5 an uncompressed situation and in a compressed situation) moves, is labeled as 36.
From Figures 6 and 7, one notes that the rear of the boot is stationary with regarct to the chassis in a sense of equal distance, because it pivots about a 3 o pivot member, for instance a pin 33. 1111hereas, the front of the boot can move upwardly or dovmwardly as pin 34 moves up and down in an elongate slot 12 as shown in Figure 3. Thus, vibration is reduced where it most occurs. The - . WO 99/56840 PCT/CA98/00443 remainder of the boot has full control and support with nrgard to the truck chassis 3.
The above description of preferred embodiments should not be interpreted in a limiting manner since variations, modifications or refinements are possible within the spirit and scope of the present invention. For instance, the boot described herein above and illustrated is designed to improve comfort and performance. Any type of boot could also be used with the present invention, for instance of rigid, semi-rigid or soft type, with or without inner finer, etc.
l0 Figure 10 illustrates an example of a different type of boot with a rigid outer shell and a soft inner liner.
The rear pivot-like member could also be different, for instance of hinge-like type. Figure 8 illustrates a variant using a standard hinge 33. Figure 9 illustrates a variant with a flexible hinge.
The pivot-like member may be provided at different locations, for instance between the bottom of the heel and the top of the chassis, as shown in figures 2, 8, 9 and 10.
The resilient member may be arranged in several ways, as shown for instance in figures 11 and 12. In figure 11, the resilient member is comprised of one centrally placed resilient pad. in figure 12, the resilient member is comprised of two laterally placed n3silient pads. In the latter case, the 2 5 attachment between the front boot portion and the front chassis portion may be achieved in using a different type of translating connection member, for instance a connecting rod arrangement (or other similar arrangement) adapted to provide limited translation movement, as shown in figure 10.
3 o The scope of the invention is defined in the appended claims and their equivalents.
As shown more clearly in Figure 3, upper cuff outer boot 9 advantageously contains a buckle aperture 16 and an upper flex pivot aperture 17. This is adapted to cooperate with lower flex pivot aperture 18 found in the lower outer boot. A flex device 19 is adapted to fit within upper flex pivot aperture 17 and lower flex pivot aperture 18.
As shown in more clearly in the upper portion of Figure 3, the liner or inner boot, consists of a rear inner boot 20 equipped with an ankle cushioning pad 20a. The liner also consists of a front inner boot 21. Rear and front inner boots 20 and 21 rest on an inner boot base 22.
The skaters foot is secured in the boot by means of laces 27 which traverse lace holders 28, these being located on a lace support pad 29 which is integrally connected to the front inner boot 21. An upper lace tightener 30 is used to tighten the laces.
Support to the ankle region and the upper cuff is provided by a strap 31 which is adapted to be secured within buckle 32 to tighten the upper cuff outer boot 9.
As shown in Figures 1, 2 and 3, a resilient member, for instance one (or more) elastomeric absorber or pad 35 is placed between the sole of boot 2 and the skate chassis 3 at the front portion thereof to provide resiliency in a substantially vertical direction as the boot 2 pivots in relation to the skate chassis 3 about pivot member 33. The pad could also be made removable. In such a case, a set of pads of different characteristics andlor different materials could be provided. The skater selects the pads according to his skills or type of skating, with more or less damping.
Figures 4 and 5 show other details of this boot embodiment. The outer boot with its various padding elements without liner portions 20, 21 and 22. The tendon cushioning portion 26 and the fifth metatarsal padding 23, are shown.
In Figures 4 and 5 one sees that the upper cuff outer boot 9 is connected to the heel sup~rt lower outer boot 6 by means of flex device 19.
In Figures 6, 6a, 7 and 7a, one views the shock absorber in an uncompressed situation and in a compressed situation. The distance between the bottom of the 2 o boot and the top of the chassis in an uncompressed situation is "X", whereas, in a compressed situation, the distance between the boot and chassis "X'" is smaller.
An arc, through which translating connection member 38, for instance pin 34 (in 2 5 an uncompressed situation and in a compressed situation) moves, is labeled as 36.
From Figures 6 and 7, one notes that the rear of the boot is stationary with regarct to the chassis in a sense of equal distance, because it pivots about a 3 o pivot member, for instance a pin 33. 1111hereas, the front of the boot can move upwardly or dovmwardly as pin 34 moves up and down in an elongate slot 12 as shown in Figure 3. Thus, vibration is reduced where it most occurs. The - . WO 99/56840 PCT/CA98/00443 remainder of the boot has full control and support with nrgard to the truck chassis 3.
The above description of preferred embodiments should not be interpreted in a limiting manner since variations, modifications or refinements are possible within the spirit and scope of the present invention. For instance, the boot described herein above and illustrated is designed to improve comfort and performance. Any type of boot could also be used with the present invention, for instance of rigid, semi-rigid or soft type, with or without inner finer, etc.
l0 Figure 10 illustrates an example of a different type of boot with a rigid outer shell and a soft inner liner.
The rear pivot-like member could also be different, for instance of hinge-like type. Figure 8 illustrates a variant using a standard hinge 33. Figure 9 illustrates a variant with a flexible hinge.
The pivot-like member may be provided at different locations, for instance between the bottom of the heel and the top of the chassis, as shown in figures 2, 8, 9 and 10.
The resilient member may be arranged in several ways, as shown for instance in figures 11 and 12. In figure 11, the resilient member is comprised of one centrally placed resilient pad. in figure 12, the resilient member is comprised of two laterally placed n3silient pads. In the latter case, the 2 5 attachment between the front boot portion and the front chassis portion may be achieved in using a different type of translating connection member, for instance a connecting rod arrangement (or other similar arrangement) adapted to provide limited translation movement, as shown in figure 10.
3 o The scope of the invention is defined in the appended claims and their equivalents.
