Shoes

Abstract

The invention discloses a pair of shoes, which has heightening and shockproof functions and is particularly suitable for driving riding tools such as motorcycles and preventing mine explosion damage. Motorcycle driving has a certain requirement for height, the height of riding shoes in the prior art is increased by thickening soles, however, the shoes can affect normal walking, and the situation that the shoes are difficult to operate when uplifting is carried out in the motorcycle driving process is likely to happen. When the shoe is used for conducting motorcycle upshift operation, the tiptoe does not need to stretch to the position below a gear lever any more, and the operation can be completed by directly lifting the tiptoe upwards. In the military field, small landmines such as a butterfly mine may cause amputation injury to the legs, and by using the shoe, the explosion impact on the feet can be reduced, and the possibility that the legs are seriously injured is reduced.

Description

Technical Field

[0001] The present invention discloses a shoe, which has height-increasing and shock-absorbing functions and is suitable for driving a riding tool such as a motorcycle. In the military field, small mines such as butterfly mines can cause serious damage to a person's legs. Using the shoe of the present invention can reduce the conduction of the explosion to the legs and reduce the possibility of injury. Background Art

[0002] Riding vehicles such as motorcycles, electric bicycles, and pedal bikes all have certain height requirements for drivers. When the driver's height does not meet the height requirements of riding vehicles, it not only affects the driving comfort, but also causes safety hazards. Therefore, a person's height limits his choice of riding vehicles.

[0003] In the prior art, in order to eliminate the adverse effect of the seat height of riding vehicles on the height of the rider, methods such as adjusting the thickness of the seat cushion, adjusting the frame structure, adjusting the shock absorption, and increasing the thickness of the sole can be adopted. The first two methods involve the design or modification of the vehicle, which may be difficult and costly without pre-design and modification parts. Although increasing the thickness of the sole is convenient and low-cost, the thickened sole will affect the operating accuracy of shifting and braking. In particular, due to the spatial structure of the footrest and shift lever of the straddled motorcycle, the thickened sole will hinder the toe from lifting the shift lever, and cannot be used for motorcycles that can lift the shift lever without stepping on the back.

[0004] In the military field, small anti-personnel mines may cause amputation of soldiers' legs. Whether during war or after war, a large number of small mines thrown will pose a great threat to the safety of soldiers and civilians. Mine clearance not only requires a lot of manpower and material resources, but is also difficult to completely clear. It is a long-term and non-ignorable safety hazard. Summary of the invention

[0005] The present invention is an improved scheme for cycling shoes that achieve the purpose of increasing height by increasing the thickness of the sole. The cycling shoes of the present invention can achieve the purpose of increasing height, and can also not affect gear shifting and braking like ordinary cycling shoes without the function of increasing height. When the gear lever needs to be lifted upward, it is no longer necessary to move the toes under the gear lever, and the upward gear shifting operation can be completed by lifting the toes, thereby improving the convenience of driving.

[0006] In the prior art, the degree of sole thickening is limited. An overly thick sole not only hinders the upward movement of the toes to shift the gear lever but also affects walking. To achieve the above-mentioned invention objective, the technical solution adopted in the present invention is to change the thickened solid sole into a "匚"-shaped one. The part in contact with the foot or shoe at the upper part is named the pedal, the part in contact with the ground at the lower part is named the floor contact plate, and the vertical part is the support column of the pedal and the floor contact plate. The thickness of the sole is determined by the length of the support column, and the length of the support column is variable and has a shock-absorbing function. To meet normal walking, the pedal must be able to adapt to the movement of the sole of the foot. Therefore, the pedal is divided into three parts: the front end, the middle end, and the rear end. The three parts are connected in sequence by a rotating shaft, enabling the front end and the rear end to bend upward. The floor contact plate is also divided into two parts: the front end and the rear end. The front end and the rear end of the floor contact plate are respectively connected to the lower ends of the support columns at the front end and the rear end of the pedal. If the floor contact plate is caught, it may cause a tripping accident. Therefore, when the floor contact plate receives a downward moment, it needs to be able to flip downward to avoid a tripping accident, but the minimum moment for this downward flip should be greater than the moment required to shift the gear lever upward.

[0007] Under an ideal model, the impact on the leg caused by a landmine explosion is inversely proportional to the cube of the distance from the explosion center to the sole and proportional to the area of the sole. The farther the sole is from the explosion center and the smaller the sole area, the less damage the leg will suffer. To reduce the impact on the sole of the foot, the support column should be as long as possible. When the floor contact plate detonates a landmine, the impact received by the floor contact plate will not be directly transmitted to the pedal. Instead, the kinetic energy obtained will be converted into the potential energy of the spring inside the support column and transmitted to the pedal. When the explosion impact reaches the pedal, it has undergone attenuation over a distance, and the impact on the pedal will be much smaller than the impact received by the floor contact plate, thus effectively reducing the damage to the leg. To further reduce the conduction of the explosion impact by the floor contact plate, holes can be added to the floor contact plate to reduce the contact area of the floor contact plate receiving the explosion impact, thereby achieving the anti-landmine function.

[0008] Although the contact floor area can be reduced by increasing the holes, if the hole area is too large, it will cause an increase in the pressure of the contact floor on the ground, making the shoes unfavorable for standing and walking on soft ground. Therefore, the contact floor is added with the function of automatically tilting under the action of a severe explosion shock to further reduce the upward conduction of the explosion shock. To facilitate motorcycle driving, the soles of the shoes have been designed in a "匚" shape, with the inner side and the front and back between the two legs being empty, and only the outer sides of the two legs having support parts. The design of the tiltable contact floor will cause debris or sundries carried by the explosion shock to have a higher probability of splashing onto the other leg and other parts of the body. Therefore, for mine protection needs, the contact floor should tilt upward and outward on both legs under the action of the explosion shock. To balance the actual needs of motorcycle driving and mine protection, the solution adopted in the present invention is that the shoes for the left foot can also be worn on the right foot, and the shoes for the right foot can also be worn on the left foot. When driving a motorcycle, the support parts are on the outside, and when protecting against mines, the support parts are on the inside.

[0009] Increasing the height of the sole will cause the ankles to be prone to sprains. To avoid ankle sprains, an anti-sprain protector is designed at the rear end of the shoe. The type of spring used for the support column can be an ordinary linear spring, or other types of springs such as a disc spring or an annular spring. Brief Description of the Drawings
