Description

Sandal material capable of transforming materials, colors and patterns, and manufacturing method thereof and special production tool

The present invention provides a sandal, and more particularly a sandal that can be converted into materials, colors, and styles. The present invention also relates to a method of making the sandal and a special combination tool for making the sandal.

Background technique

A large part of the sandals that people wear in the summer are made up of strips. The sandals of the sandals of the prior art are constructed such that the ends of the uppers (also referred to as the upper legs) are fixed in the interlayer of the sole, or are sewn or glued. The strips above the soles are interlaced to form the upper. Due to the structure and processing limitations of this type of sandal, the style, color and material of the upper can not be changed. Similarly, for the sole, the style of the sole, especially the height of the sole, is fixed and invariable with respect to one style of upper. In modern civilized society, people pursue the harmonious unity of clothing, and the style and color of shoes should be reasonably matched with the style and color of clothing. However, the above-mentioned pair of sandals in the prior art cannot satisfy the needs of people to harmoniously match various styles and color costumes.

Summary of the invention

The object of the present invention is to improve the deficiencies in the prior art, and to solve the problem that the style, color and material of the upper or the sole can not be changed once the existing sandals are made, and the utility model can provide a strip of sandals. The upper and the sole constitute a structure that can be easily disassembled, so that the sole can be combined with a variety of styles, materials and colors of the upper or the upper can be combined with different styles of the sole to be converted into a variety of styles, colors and materials. The upper and the sole are designed to match the material, color and style of the sandals with reasonable and harmonious matching.

Another object of the present invention is to provide a method of making the above sandal.

It is still another object of the present invention to provide a special tool for use in the above-described method of making a sandal.

The object of the invention is achieved in this way:

The sandals provided by the present invention include a sole and an upper belt. In the prior art belt sandals, in the shoe industry, the end of each upper belt fixed to the sole is an upper foot. Here, we will use the upper and the sole. The fixed part is called the upper fixed position of the upper.

The sandal provided by the present invention forms a plurality of wearing passages in the sole between the upper belt fixing positions of the sole, and each of the wearing passages is provided with a passage opening on a side wall of the upper upper fixing position of the sole; At least one auxiliary passage is provided in the sole, which communicates with at least a part of the wearing passage, thereby forming a network of passages formed by the wearing passage and the auxiliary passage in the sole, the auxiliary passage being at the front end of the sole and / or at least one passage opening on the side wall of the rear end;

The upper belt is a belt having a width and a thickness respectively matching the width and height of the wearing belt passage and the auxiliary passage on the sole, so that the upper belt can be inserted in the passage network; A portion of the upper strap is threaded into the channel network in the sole and the remainder is placed over the sole to form the upper.

The wearing belt passage may be a transverse passage extending in a width direction with respect to the sole, and/or an inclined passage forming an angle with a width direction of the sole; the upper portion of the upper belt may be different A plurality of said wearing passages are extended in the direction. It is thereby possible to provide an upper in which the upper belt passes in such a belt passage and an auxiliary passage to constitute various structural patterns above the sole.

Preferably, the width of the auxiliary passage is at least 2-3 times the width of the threaded passage. This is because when the upper belt is worn in the wearing belt, in order to constitute a different upper style, the upper belt may pass through the auxiliary passage more than once, if the width of the auxiliary passage is equal to the width of the wearing passage, This will limit the number of passes of the upper band, thereby reducing the type of pattern in which the upper band constitutes the upper, and at the same time, the wider auxiliary passage allows the operation of the upper band to be passed through and turned over easily.

Preferably, the auxiliary passage is a longitudinal passage extending relative to the length of the sole, and a passage opening on the side wall of the sole is preferably provided on the rear side wall of the sole. Since the general auxiliary passage is made wider, the passage opening is placed on the rear end side wall of the sole to avoid entering more dust in the wearer. The longitudinal auxiliary passage is equivalent to the distance of each of the wearing belt passages, which can make the upper length of the upper belt in the sole to be shorter, and improve the use efficiency of the upper belt; the longitudinal auxiliary passage is preferably provided in the width direction of the sole. Strips, respectively, near the two side edges of the sole. Such a longitudinal auxiliary passage can make the length of the belt in the passage shorter in the passage of the upper belt, and is also convenient to wear.

Preferably, the passage angle of the intersection of each of the through passages and the auxiliary passages in the sole is an arcuate corner, which facilitates passage of the belt when the upper is worn.

Preferably, the material of the sole for forming the wearing passage and the auxiliary passage is a material having sufficient hardness and certain toughness, so that the through passage and the auxiliary passage are not deformed when the sandal is worn, and Give the sole a better comfort. To achieve this, the structure of the sole may be such that:

The sole includes an insole, an upper bottom, a midsole, an outsole and a shoe root having substantially the same shape from top to bottom, and the above parts are fixed together by bonding or sewing;

The midsole may be: a midsole upper pad, an intermediate layer constituting the channel network, and a midsole lower pad, and the midsole upper and lower pads are preferably metal plates such as manganese steel plates or stainless steel. The board is formed, and the middle layer of the channel network is a plurality of channel spacers, wherein the upper and lower end faces of the channel block are respectively fixed to the upper pad and the lower pad, and each channel spacer and upper and lower pads The channel network is formed by being fixed between the spacers.

The upper and lower pads function to form the wearing channel and the auxiliary channel together with the channel spacer. The metal plate is used to effectively prevent the deformation of the channel, but the shoe sole is more likely to be worn. For this reason, a hollow hole may be formed in the upper and lower pads, and the hollow hole is opened at a position opposite to the channel spacer and offset from the channel network. This design can not only reduce the problem of hard and uncomfortable shoe soles, but also effectively reduce the weight of the sole. In addition, at the hollow hole, the passage The spacer can be in contact with the upper bottom and the outer bottom, and an adhesive layer is interposed therebetween to improve the adhesion of the sole as a whole. The size of the hollow hole should match the size of the channel spacer: The hollow hole should not be too large, so that there should be enough contact area between the upper and lower pads and the channel spacer to bond the upper and lower pads to the channel spacer by bonding.

The upper and lower pads of the midsole may be identical to the shape of the sole or may be inconsistent: if the midsole portion is vacant on the portion of the sole corresponding to the passage where the passage is not provided, the passage spacer and the upper base and/or The outsole is directly consolidated, which further reduces the weight of the sole and enhances the comfort of the sole.

The intermediate layer constituting the channel network may also be such that a groove-like or square-tube channel body is disposed in the above-mentioned channel network formed between the respective blocks, and the spacer is disposed around the channel body; The passage body may be a closed tubular passage body having an upper floor lower floor and two side wall plates, which are fixed between the upper bottom and the outer bottom. The channel body may also be a semi-closed channel-like channel body having only one of the two side wall plates and one of the upper bottom plate or the lower bottom plate. In this case, the semi-closed groove-shaped channel body is on an open bottom surface thereof. A corresponding midsole pad is provided, and the other bottom plate is directly attached to the upper or outer bottom. Preferably, each of the channel engaging portions at the intersection of the channels in the slotted or square tubular passage body is designed as a tapered connecting structure which allows the upper band to pass through more easily in the passage.

The sandal provided by the present invention may further comprise an upper belt pad, which is provided with a belt loop hole, the size of the belt loop matching the width and thickness of the upper belt, the cushion being placed above the sole The upper belt may have the following functions: First, the knot of the end of the upper belt is placed on the cushion so as to separate the knot from the foot of the user wearing the sandal. There is an uncomfortable feeling such as a mattress; another one is that the pad can be made into various decorative shapes or decorated with a decoration on the pad, which can be worn on the upper band to beautify the decoration; The pad provided on the upper strap may form part of the upper, thereby increasing the firmness of the formed upper, which may also be easier and more convenient to wear than forming the upper with the upper.

At least one of the ends of at least one of the upper strips may be provided with mutually compatible joint members for easy disassembly or fixation, such as buckles. Thereby, the shoe buckle device of the sandal provided by the present invention is constructed.

Eliminate. The outer portion of the cleaning portion is smaller than the cross-sectional dimension of the passage on the sole.

The sandstone provided by the present invention has a common structure in which the upper belt is fixedly coupled with the sole, and the upper is formed by the upper of the upper belt provided with the wearing passage and the auxiliary passage, so that a pair of shoes cooperate with a plurality of upper belts. The upper can be arbitrarily changed in style, color and material depending on the designer or the wearer's concept. Similarly, a set of upper straps can also be combined with several different soles having the same passage section size to form different shoes, for example. Several pairs of soles with different shoe root heights, with a set of uppers, can get different sandals. Therefore, there is no need to put a lot of shoes for a variety of clothing or various occasions to attend. In addition, the upper of the sandal is formed by the upper belt passing through the passage network of the sole, so that the user can not only design the style of the upper as desired, but also can form the upper of the size according to the shape of the foot of the foot. It is also possible to solve the problem that the shoes in the prior art are not because the number does not match the foot but because the shoe type and the foot are not fit, and the user can weave the upper of the favorite style according to the shape of the foot. Further, the existing sandals for the belt uppers are broken due to the thinner belts, and the belts and the soles are broken at the fixed points, and sometimes the repair is difficult, and a pair of shoes are scrapped. In the sanding of the present invention, if the upper belt is damaged, it is only necessary to replace one upper belt. In addition, the sandals provided by the present invention pass through the passage in the sole and the connection to the sole is very strong. Furthermore, since the passage network on the sole of the sandal provided by the present invention is provided with a wearing passage for the upper belt, an auxiliary passage is provided through which the auxiliary passage can be woven on the sole with a special tool. A variety of patterns of uppers, at the same time, it is easier to wear, if there is no auxiliary channel, we must weave a variety of upper styles, sometimes the uppers are placed on the outer side wall of the sole, which will affect the aesthetics of the shoes. The channel on the sole of the sandal provided by the invention is formed by the channel isolation and the midsole upper and lower pads, which is more difficult to deform than the channel formed by directly connecting the channel or the groove on the plastic or rubber sole, and the transformable pattern is The color, material structure is used to make high-grade leather sandals, and it can meet the needs of people who wear high-end sandals.

According to the sole sample design, the channel network sample is made. When the sole sample and the channel network sample are overlapped, the sole-like portion not covered by the channel network substrate is the shape of the channel spacer and its position on the sole. In this way, the leather area of the spacer is calculated, and the leather is first rolled, passed through, and finished so as not to be deformed in the subsequent wearing to deform the channel network, and then trimmed and trimmed. It should be noted that the thickness of each channel spacer 1042 should be the same. The shape of the upper and lower pads 1041 and 1043 is stamped by manganese steel sheets, and the hollow holes d are punched out according to the design requirements. A riveting reserved hole is also formed at the corresponding shoe root on the upper and lower pads, and a riveting reserved hole is also provided at the front end of the corresponding toe of the pad, which is also formed by one punching as described above, therefore, When designing stamping dies, all of the above factors should be well considered.

Here is the assembly of the sole:

Making a midsole:

The sole sample and the channel network substrate are overlapped (it can also be made into a sole sample with a channel network base of the shoe), and the prepared channel spacers 1042 are placed on each part of the sample at each predetermined position, and the inspection is performed. After the error, the bonding part on one side of the channel spacer and a corresponding midsole pad need to be coated with adhesive on the part where the channel spacer is bonded, and then fixed and fixed, and then checked and cleaned. The spacer performs the same bonding operation as the other midsole pad. It should be noted that the pressure of the bonding profile is such that the thickness of the midsole after bonding is consistent, and the height of the channel formed meets the design requirements, i.e., the height is greater than the thickness of the upper band. The upper and lower pads and the channel spacers of the rivet rugged midsole are arranged in the riveting reserved holes at the front end of the pad by rivets. Then, carry out the leveling and finishing, check and clean up the debris, make the midsole clean and tidy, and the channel network is smooth.

If the midsole is made by a slot plate or a square tubular channel body as shown in Fig. 8, the following is the case: a channel network base is designed according to the sole sample, and the base of the slot plate or the square tubular channel body is formed according to the channel network sample. Note that the height should be greater than the thickness of the upper band, and its width meets the above requirements. The corner of the passage (the intersection of the belt passage and the auxiliary passage) is a divergent connection structure. The machined transverse channel slot plate base (with flare) is then coupled to the longitudinal channel slot plate base. If the grooved base is made of a metal material, it can be joined by welding, such as a grooved base made of a non-metallic material, which can be joined by bonding. After connecting The base channel should be cleaned. The passage body 1044 is completed by making a passage cover according to the shape of the passage, and then fixing the cover to the groove base by welding or bonding.

Making a sole - The midsole made in the above steps is assembled with the insole, the upper sole, the outsole and the root.
