Description

Power-assisted shoes

The technical field is as follows:

the invention relates to a pair of power-assisted shoes.

Background art:

in order to improve the functions of the shoes such as light, labor-saving, soft and comfortable, people continuously research and develop power-assisted shoes. The conventional power-assisted shoes (Chinese patents ZL200420063139.2 and ZL201620000706.2) with the front ends and the rear ends tilted upwards are power-assisted shoes manufactured by utilizing a lever principle, namely lever type power-assisted shoes, no matter the soles are provided with hard plates (or hardened soles) or tensile layers. The existing lever type power-assisted shoes have the advantages that the sole technology is continuously improved, but the inherent defects of uppers exist all the time and cannot be overcome, so that the problem which puzzles the shoe industry for a long time is solved.

The lever type power-assisted shoe consists of a sole and an upper. The power of the lever type power-assisted shoe is from the sole and the upper. Therefore, the assistance to the upper is always the problem of the attack of the shoe industry; and around the problem of 'shoe upper assisting force', a plurality of technical schemes are provided. Firstly, in order to enhance the power assistance of the upper, a strong shoe material is used for manufacturing the upper. Thus, the assistance is enhanced, but the upper is stiff, and even the sole and the heel cannot fall down simultaneously due to the over-tight pulling of the upper, so that the shoe cannot adapt to daily wearing requirements. Secondly, the upper is made of no strong shoe material in consideration of being suitable for daily wearing. Therefore, the sole and the heel can fall to the ground at the same time, but the power assisting force is insufficient due to the loose upper, so that the power assisting shoes are not different from common shoes. Thirdly, in order to solve the problem of difficulty in assisting force, shoe materials with low strength are used instead to manufacture uppers with proper assisting force. As a result, once worn, the upper "tightens first and loosens", and the assistance drops rapidly, quickly and no further than with an otherwise loose upper. Fourth, even if the shoes with a moderate and strong power assistance are elaborately made, they are bound to face an insurmountable difficulty when worn on the foot: when the walking stick is taken a step, the sole rebounds untimely, the heel is not tightly supported, the power supply is slow, and the due power-assisting effect is inevitably weakened.

In addition to the above-mentioned problems of uncontrolled "upper assist", there is also a potential problem of loss of "upper assist". When a person wears the lever type power-assisted shoes to stand, the soles are under the action of the gravity of feet (human bodies), the upward raised parts at the front and rear ends of the soles descend, and the process of descending the raised parts is the process of flattening the soles, namely the process of longitudinally lengthening the soles. The sole and the upper are integrated, and the sole is lengthened, so that the upper is necessarily stretched. The detrimental downward movement of the upper occurs during longitudinal stretching. The upper can strongly press down toes, instep and heel, which makes people feel uncomfortable; but also causes serious wrinkles of the upper, which affects the beauty of the shoe product. For power-assisted shoes, however, the downward movement is more disadvantageously greatly distributed and the longitudinal stretching movement of the upper is reduced. The force formed by the longitudinal stretching movement of the upper is the assistance of the lever type power-assisted shoe; the force lost by the downward movement of the upper is the valuable power assistance of the lever type power assistance shoe. In conclusion, the loss of the power assistance of the upper is an unreserved fact and a long-pending problem in the industry.

In summary, the problem that the obvious 'assistance force' cannot be controlled or the potential 'assistance force loss' cannot be stopped is the 'upper assistance' problem of the lever-type assistance shoes. The upper of the lever-type power-assisted shoes has various styles, and shoe materials are different, so that the design is diversified, the sentence is one, the head is numerous, the contradiction is serious, and the variety is great, so that the problem of 'upper power assistance' of the lever-type power-assisted shoes is a problem which is troubling the shoe industry for more than two decades, and the problem is still not solved today.

The invention content is as follows:

the invention aims to solve the technical problems in the prior art and further provides a lever type power-assisted shoe which is moderate in strength, rapid in force application and durable in function.

The technical scheme is as follows: the utility model provides a helping hand shoes, its sole that has lever helping hand shoes which characterized in that: the upper part of the sole is provided with an elastic upper and a hard support.

Has the advantages that: in order to solve the prior technical problem, firstly, a hard support is arranged. The hard support has the functions of keeping the appearance of the shoe product stiff and smooth and keeping the foot stable in the shoe in the upper of the common shoe. In the special structure of the lever type power-assisted shoes, under the action of the gravity of the feet (human body) in a special power-assisted system, the new and important functions of the hard support are as follows: the longitudinal stretching movement of the upper is formed in a centralized manner, so that the power assisting function and the power assisting effect are enhanced. In particular, the upper of the lever-type power-assisted shoe is provided with the hard support, particularly the hard support of the middle upper, when the sole is subjected to the gravity of human feet (human body) and the front end and the rear end of the sole are raised upwards and lowered, the hard supports of the front upper, the middle upper and the rear upper are firm and stand, the upper is longitudinally tensioned and straightened, and the downward movement of pressing toes, instep and heel of the upper is effectively inhibited; meanwhile, the upper is intensively completed by the strong support of the hard support, and the vertical movement and the vertical stretching movement of the upper are completed. Therefore, the loss of the power assistance of the upper is effectively restrained, the power assistance of the upper is greatly gathered, and the new, complete, sufficient and powerful power assistance of the upper is obtained.

Secondly, an elastic upper is arranged. The elastic upper is used in common shoes, and is required to fit feet and be soft and comfortable. In the special power-assisted structure supported by the hard support of the lever type power-assisted shoe, under the gravity action of the human foot (human body), the functions and the effects of the elastic shoe upper are greatly different. After the elastic upper is used in the lever type power-assisted shoe, when the front end and the rear end of the sole descend (ascend), the elastic upper does longitudinal stretching (contraction) movement under the action of the hard support, so that the power-assisted function of shock absorption and rebound is generated, the power-assisted function of shock absorption and rebound is achieved, and the power-assisted effect of shock absorption and rebound is achieved. In particular, the lever-type power-assisted shoe has the advantages of using the elastic upper: firstly, the stiffness and over-tightness of the upper are avoided, and the sole heel is ensured to land stably at the same time; secondly, the elastic upper with high stretching strength is selected, so that the strong power can be ensured, and the power cannot be weakened due to the looseness of the upper; thirdly, within the elastic limit, the assistance generated by the elastic upper is stable and durable and cannot drop rapidly; fourthly, the elastic shoe upper is quick in rebound, quick and powerful in power assisting response and capable of actually obtaining complete and sufficient power assisting effect.

In addition, due to the combined action of the hard support and the elastic upper, the descending of the upper can be effectively inhibited, and the foot pressing and foot squeezing are not performed any more; the shoe can also reduce the wrinkles of the upper by means of inhibiting descending, and keep the shoe shape as stiff and smooth as before; it also ensures the softness and comfort of the upper and the stability of the foot in the shoe.

It should be further noted that the processes of descending of the raised parts at the front end and the rear end of the sole, the support body being arduous, and the elastic upper being tensioned and straightened are processes of accumulating elasticity of the upper of the power-assisted shoe, and also processes of the upper of the power-assisted shoe and the sole playing a role in shock absorption together. When the heel is lifted, the raised parts at the front end and the rear end of the sole are lifted, the support is relaxed, and the state of the elastic upper being tensioned and stretched is eliminated, namely the process of releasing the elasticity of the upper, namely the process of playing a rebound role together with the sole of the power-assisted shoe.

In conclusion, practice proves that the assistance of the lever-type power-assisted shoes comes from the sole and the upper. The hard support is organically combined with the elastic upper, so that the power-assisted force of the upper can be controlled, the power-assisted loss of the upper can be prevented, the potential of the upper of the lever-type power-assisted shoe can be developed, and the new powerful power-assisted upper can be formed. Therefore, as long as the longitudinal stretching and shrinking actions of the upper are fully and effectively exerted, namely the tight combination and perfect superposition of the power assisting of the upper and the power assisting of the sole, the lever type power-assisted shoe with moderate strength, rapid power supply and lasting functions can be manufactured.

It should be noted that the term "longitudinal" as used in the specification and the abstract of the specification of the present invention means a direction from the toe end to the heel end.

Description of the drawings:

FIG. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

as shown in fig. 1, a tensile layer (or hard plate) 2 is arranged in a sole 1 with front and back ends tilted upwards; on the upper part of the sole 1, there are provided a hard support 3, a hard support 4, a hard support 5, and an elastic upper 6, 7. The hard support, the elastic upper and the sole are integrated into a whole through gluing, stitching, injection molding, 3D printing and the like to form the whole shoe. The

hard supports

3, 4 and 5 are respectively positioned at the front upper part, the middle upper part and the back upper part of the upper. Wherein, the supports 4 at the middle upper part are oppositely arranged at the left side and the right side of each shoe; the support 3 at the front upper part can be integrated with the front port treasure; the support 5 at the back part can be integrated with the 'rear port treasure'. All of the rigid supports may be located in the midsole of the upper, or may be located on the inner side of the upper or on the outer side of the upper. The support of the upper can be integrated with the ornament (sheet), and other methods capable of supporting can be selected to achieve the expected effect. And the support is made of plastic, rubber, metal and other materials capable of playing a supporting role. The hardness, rigidity and toughness of the support and the shape, position and quantity of the support can be flexibly applied and properly adjusted according to the style characteristics, functional requirements and other conditions of the shoe product, so that the style and the function of the shoe product are comprehensively balanced and perfectly combined. The elastic shoe upper is made of fabric with good resilience, high stretching strength, softness and bending resistance or other materials with similar performance. The upper of the shoe product can be an integral elastic upper; a hybrid upper combining zoned, elastic and inelastic portions is also possible. The hybrid shoe upper may be a combination of two parts, elastic and non-elastic, or a combination of alternating portions. The shapes, areas, thicknesses and the like of all parts also need to be flexibly allocated and specifically determined according to the style characteristics, functional requirements and other conditions of the shoes.

It is important to note that, whether the elastic portion of the shoe upper is a unitary elastic shoe upper or a hybrid shoe upper, all the components thereof, including the upper, the upper lining, the upper liner, the trim (panels), the reinforcement, etc., are preferably made of an elastic material to ensure the stability and durability of the elastic properties that it should have. It is also possible, if part of the normal non-elastic material has to be selected, only that the function will be less. The upper of the non-elastic part is made of a main material which has high tensile strength, low elongation at break and flexibility; on the contrary, if the material with low tensile strength and high elongation at break is selected as the main material, the longer the upper is pulled, and the looser the upper is pulled, the assisting force is rapidly reduced. The upper assistance force of the assistance shoe is determined according to the requirements of the shoe product; the achievement of the power-assisted force of the upper can be realized by adjusting the stretching strength, the area, the thickness and other relevant factors of the used elastic material; in special conditions, the elastic area of the upper can be reduced as much as possible, and even the upper and the support are integrated into a whole. In addition, it is known that when a sole is provided with a hard plate (or the sole is hardened), the higher the hardness (rigidity) is, the stronger the assisting force is, and meanwhile, under the action of the gravity of the human foot (human body), the stronger the force for pulling the upper is, and the stronger the assisting force generated by the upper is; the lower the hardness (rigidity), the weaker the assist force, and the weaker the force of pulling the upper by the gravity of the human foot (human body), the weaker the assist force generated by the upper. The sole is provided with the hardness of the hard plate (or the sole is hardened), in the technical scheme, the sole can pull the upper in motion to enable the upper to participate in boosting formation, and the sole and the upper form the whole boosting force of a shoe product to meet the requirement of the shoe product. Therefore, if necessary, non-hardened soles can also be used, but with a smaller power assistance.
