Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shoe having a shock-

The present invention relates to a shoe, in which a shock absorber is assembled on the bottom surface of a shoe so as to provide ease of assembling the shock absorber to a single midsole and to provide different buffering forces or a variety of designs.

A shock absorber is provided to cope with a movement load generated when walking or running while the outsole is attached to a midsole or a midsole forming a bottom surface of a current shoe.

Therefore, as an example of such a shock absorbing means, an airbag may be inserted between the midsole and the outsole of the foot so that the entire midsole of the shoe is foam-molded, or the airbag is mounted on the horseshoe portion of the foam- will be.

However, when the whole of the midsole is formed by foam molding, the production cost is increased as the weight is lower in the molded state, and it is impossible to maintain the optimum line of price quality because the production cost is increased.

Therefore, when the airbag is mounted on the midsole to realize the buffering force with a low weight, the airbag is formed of plastic, which makes it difficult to keep the airbag. Therefore, when the airbag is used for a long period of time, air is released, In addition, when the airbag is formed in the middle of the midsole of the shoe, the airbag is formed in the state where the airbag is mounted during the foaming molding, And there is a possibility that molding may be difficult due to molding.

Therefore, in order to solve such a problem, the inventor of the present invention formed a buffer hole through the side of the midsole forming the bottom surface of the shoe so as to minimize the rise in the cost of the foam molding while improving the buffering force.

However, in order to form a buffer hole in such a case, the diameter of the buffer hole must be detached and coupled to the metal mold during the foaming molding. In this case, the bonding line is formed entirely on the midsole of the midsole, When the shock absorber is equipped with the shock absorber, the shock absorber directly penetrates the midsole of the shoe. In order to form the shock absorber hole, the end of the midsole is formed as a whole so that the shock absorber is not formed. And there is a problem that the feeling of fit may be deteriorated due to the difference in the buffering force of the portion where the buffer hole is formed and the buffer portion of the portion where the buffer hole is not formed.

Therefore, the applicant of the present application proposed a method of attaching the buffer tube penetrated to the bottom surface of the midsole to solve this problem. However, when the buffer tube is pressurized during the bonding, the buffer tube is distorted and the accurate adhesive force can not be maintained. It is impossible to maintain the quality uniformity in one state.

In addition, since all of these methods require different molds in the case of forming the same size of midsole according to the shape of the buffer hole, it is impossible to realize various buffer holes in the same size of the midsole. For diversity, It was the cause of substantial cost increase.

In addition, such a product has a problem in that it is impossible to provide a buffer means to cope with a change in the degree of damage of the midsole due to the walking habit of the pedestrian.

Therefore, the present invention enables various types of shock absorbers to be easily assembled to one midsole that forms the bottom surface of a shoe so that a shock absorber having diversity can be realized in one midsole. In addition, It is also possible to provide shoes but not raise costs.

To this end, a supporting groove is formed on both sides of the upper side of the opening groove and a single or a plurality of opening grooves on the bottom surface of the midsole of the shoe, and a shaft and a flange are provided so as to be supported by the opening groove and the supporting groove And then the adhesive tube is made to adhere.

And a cushioning tube made of a cushioning tube for allowing the shaft and the flange to be supported by being pinched by the opening groove and the cushioning groove by making the upper side of the midsole in the state where the opening groove and the cushioning groove are formed, And after the assembly, the insole is provided on the upper surface of the flange.

And a pair of supporting grooves are formed on the outer side of the upper side of the opening grooves provided on the pair of supporting grooves so as to be inserted into the opening grooves, And a flange extending only to the upper end of each of the shafts after being separated from each other.

In addition, when the cushioning tube is coupled to the midsole as described above, a curved groove is provided outside the opening groove formed in the bottom surface of the midsole so that a part of the upper side of the cushioning tube of the cushioning tube can be inserted. It is possible to prevent the shaft of the buffer tube from being tilted to the left or right due to the twist due to the momentary force change of the buffer tube while the upper end is simultaneously bonded to the curved groove.

Also, it is possible to provide a shoe having various shapes and functions by making the buffer tube of the buffer tube different in hardness or different in size from the others.

Accordingly, it is possible to provide a customized footwear having various functions or forms by using a cushioning tube having various cushioning tubes of various hardnesses and diameters, and adhering and fixing the cushioning tube according to the position and the number of the opening grooves in one midsole When the cushioning tube body is assembled, it is possible to easily and firmly adhere to the flange of the cushioning tube body and the bearing surface formed on the midsole. In particular, when the cushioning tube body is formed by a plurality of shafts, The buffering force can be maintained even when a load is generated and a part of the upper surface of the buffer tube is inserted and adhered to the bottom surface of the midsole at a predetermined area so that the restoring force due to the zigzagging of the buffer tube is excellent And shoes of various designs can be provided as a single midsole.

In addition, since only the buffer tube of the buffer tube is exposed at the bottom surface of the thin midsole, excellent buffering force and low weight can be realized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in the drawings, the configuration of an embodiment of the present invention is characterized in that a supporting groove is formed on the bottom surface of the midsole of the shoe, and a pair of supporting grooves are formed on both sides of the opening groove, A buffer tube made of a buffer tube for supporting the shaft and the flange so that the shaft and the flange can be supported can be easily pinched and adhered.

That is, the opening grooves 111 formed in the bottom surface 110 of the shoe 100 at regular intervals and the opening grooves are formed to have a constant depth alpha, and the supporting grooves 112a and 112b The adhesive portions 113a and 113b are formed in a state where the support grooves are formed.

The shaft 11 and the flanges 12a and 12b are inserted into the opening groove 111 and the receiving grooves 112a and 112b formed on the bottom surface of the shoe so as to be adhered to the adhesive portions 113a and 113b, And the shaft 11 is provided with a cushioning tube 10 having a cushioning tube 13 as a means for cushioning. Then, the shaft and the flange are inserted into the opening groove and the cushioning groove, And adhered and fixed to the adhesive portion.

At this time, the depth (?) Of the opening groove is preferably made equal to or less than the length (?) Of the shaft so that the shaft is adhered and fixed in an elongated state so that the buffer tube (13) can be closely contacted to the bottom surface It is preferable to form it and by doing so, the adhesive force can be made excellent.

Therefore, when the buffer body 10 is adhered and fixed as described above, when an instant load is applied during walking or jogging in the state of wearing shoes, the buffer tube 13 is buffered, Only the buffer tube 13 of the cushioning tube 10 is exposed to the outside on the bottom surface 110 of the shoe so that all of the space except the buffer tube 13 is formed in the space γ, It is possible to realize a weight of a small weight, and various shoes can be designed according to the arrangement of the cushioning tube 10, and a shoe having various functions can be realized.

Next, when the cushioning tube is adhered to the bottom surface of the shoe, the upper side of the midsole is opened in a state in which the opening groove and the receiving groove are formed as a yet another embodiment of adhesive fixation, The cushioning tube made of a cushioning tube for allowing the shaft and the flange to be provided can be improved in easiness of assembly. After assembling, the cushioning tube is provided with an insole on the upper surface of the flange.

That is, the upper side of the bottom surface of the shoe, in which the opening groove and the receiving groove are formed, is opened, thereby facilitating the assembly of the shaft and the flange of the cushioning tube. In this case, after the cushioning tube is assembled, The insole is adhered and fixed to the upper side by means of the adhesive so that the insole is overlapped with the shaft and the flange of the cushioning tube in a state where the shaft and the flange are adhesively fixed to the opening groove and the support groove.

Next, as another embodiment of the opening groove and the receiving groove of the cushioning tube and the bottom surface of the shoe, the opening groove is provided at a distance from the bottom surface of the shoe so as to be spaced apart from each other, And a flange extending only to the upper end of each of the shafts after the shafts are separated from each other so as to be respectively inserted into the pair of opening grooves, It can be done.

This is because when the buffer tube is exposed on the bottom surface of the shoe, it is extended by the shaft, and the buffer tube is not fixed in the extended state and is fixed only by the shaft, A pair of opening grooves are provided on the bottom surface of the shoe so as to be spaced apart from each other by a predetermined distance. A pair of supporting grooves are formed on the upper side of the opening groove provided on the pair, respectively And a bonding portion is formed at a portion where each supporting groove is formed.

Each of the cushioning tubes also has a pair of shafts and a flange on the outer side of each of the shafts so as to be inserted into the corresponding one of the opening grooves.

Therefore, the buffer tube of the buffer tube is supported by the pair of shafts in a state of being coupled to the bottom surface of the shoe, so that a lot of reinforcements can be made at the time of twisting.

Next, in order to sufficiently reinforce the cushioning tube of the cushioning tube and slimming the shoe, a part of the upper side of the cushioning tube of the cushioning tube is coupled with the cushioning tube as described above A curved groove is further provided outside the opening groove formed in the bottom surface of the midsole so that a certain portion can be inserted into the bottom surface of the shoe, that is, the midsole, so that the shaft of the cushioning tube is inserted into the opening groove, It is possible to prevent the shaft of the buffer tube from being tilted to the right and left due to the momentary force change of the buffer tube in a state where the upper end portion is simultaneously adhered to the curved groove, and the midsole can be slimmed It can be.

That is, a curved groove corresponding to the upper surface of the cushioning tube of the cushioning tube is formed on the bottom surface of the midsole of the shoe about the portion where the opening groove is formed, and the curved groove is curved downward on the upper surface of the cushioning tube So that even when the buffering force of the buffer tube is twisted, it is possible to make a new design as well as an excellent buffering force.

Also, the curved grooves are equally applicable to the case where the opening grooves are a single number or a pair of curved grooves.

In addition, by varying the thickness of the shaft of the cushioning tube or the size or elasticity of the cushioning tube of the cushioning tube to various degrees or degrees of elasticity, it is possible to provide various types of shoes to a single midsole It is possible to reduce the cost as well as the productivity.

For example, when one or two cushioning tubes are placed so as to cross each other at a position where the concave portion of the soles of the sole is formed at the center of the bottom surface of the shoe, shoes without a backsheet can naturally be provided. It is possible to make the pressure of the concave portion of the sole of the foot also possible. Also, in the case of using the cushioning tube in the form of a block, the position of the cushioning tube of the cushioning tube is varied And thus it is possible to solve the walking habit of these persons.

Therefore, it is possible to provide a variety of shoes as a mold of a single midsole by forming the opening grooves in different positions and shapes with a single midsole, and it is also possible to provide customized shoes.
