Foot-controlled thin sole step-skating shoes

Technical Field

The invention relates to a foot-controlled thin-sole walking shoe for walking and sliding, which comprises a walking and sliding working condition conversion component, a layout of each component, a main application and a working condition conversion method thereof.

Background

With the acceleration of urbanization, the improvement of housing conditions and the congestion of urban traffic, people who need to transfer for a plurality of times through buses and subways are increased continuously, and in view of the limitation of station layout of the buses and the subways, people who use the traffic mode to work and go out need to have more than 2 sections of roads to walk. In order to complete the distance of more than 2 sections more conveniently, labor-saving and safely, people want a plurality of methods, such as bicycle relay, which can solve one section but can not solve a plurality of sections, and the problem of parking is also solved; the electric single-wheel balance vehicle is fast in use and labor-saving, if the door-to-door travel is preferred, if the vehicle needs to be changed, a user can carry the vehicle with 8-10 kg, and the vehicle is inconvenient; in addition, the shoes for walking and skating have the following problems, such as the patent 'multifunctional four-in-one sports shoes', the patent number 201120364136.2 and the patent number 00243724.4 of 'sports and roller skating dual-purpose shoes': when the roller is opened and taken in, although the improvement is made, the working condition is converted by pressing a button, the working condition is locked by a rotary button, although the video demonstrates that two shoes are touched once, the roller of one shoe can be put and taken out, but the advertisement is operated under the condition that the working condition is not locked, and no safety guarantee exists, the patent specification still needs to rotate the button after pressing the button, for safety, the roller is still locked by rotating the button according to feet when the working condition is converted, if the vehicle needs to be changed for a plurality of times, the repeated conversion of walking and sliding modes is still very troublesome, not convenient and fast enough; thirdly, a connecting rod is used for pushing the working condition switching mechanism, and the working condition switching mechanism with a complex transmission path cannot be driven; fourthly, if the bicycle is used on duty every day, the bicycle is difficult to avoid meeting accidents, cannot slow down in time, and is not safe enough; it is believed that the foregoing has also been contemplated by the prior inventors, but no solution to the problem has been found.

Disclosure of Invention

Accordingly, the present invention provides a foot jumping method for conveniently and rapidly switching working conditions, that is, the ankle joint is rotated to control the working condition switching.

The foot-controlled thin sole walking skate is provided with a chassis which can be combined with a sole to manufacture, a front wheel bracket, a rear wheel bracket, a front wheel, a rear wheel and a control component, wherein the two sides of the front end of the chassis are provided with the front wheel bracket, a front wheel box and the front wheel; the rear end of the chassis is provided with a rear wheel bracket, the outer side of the rear wheel bracket is provided with an upper supporting shaft and a lower supporting shaft, a rear wheel box is arranged on the rear wheel bracket, the rear wheel box can rotate outwards and forwards and is lifted to the upper part of the sole surface at the outer side of the heel, the middle part of the front wheel front bracket is provided with a long-stroke self-locking switch, the whole layout moves parts originally limited in the sole to the periphery above the sole, the original thick sole returns to the thickness of the common sole, and the phenomenon that the original thick sole is not suitable due to the increase of the thickness and the potential danger is caused no matter walking or sliding can be avoided.

With the change of the layout, the height of the sole is reduced during the sliding, the distance between two front wheels and the distance between the front wheel and the rear wheel are increased by more than seven, the stability during the sliding is greatly increased, the technical difficulty of use is reduced, and people with a little age also have the possibility of use.

With the change of the layout, the wheel diameter is not limited by the thickness of the sole, and after the wheel diameter is increased, the pulley is more suitable for sliding on the ground with poor flatness.

With the change of the layout, the front wheels at the inner side are arranged at the front section of the inner side of the shoe, the use of partial people is still influenced, the wheel box occupies about 15 degrees of deflection angle for the sliding working condition, and for the walking working condition, because the wheel box is turned over above the vamp, only the front wheel bracket occupies 9 degrees of deflection angle, therefore, the front wheel shoe can be conveniently used for people who have foot deflection angles above 10 degrees originally in the walking habit or people who are willing to increase the foot deflection angle in the use process so as to avoid the left and right mutual contact.

The control part of the foot-controlled thin-sole walking slipper adopts pull ropes and steel wire transmission, connects ankle hoops and pull rings through the pull ropes, and then connects steel wires on a self-locking switch through guide steel pipes and related parts, and finally connects to the front and rear wheel locking bolts, so that the control part is provided with a jumping foot to extract the front and rear wheel locking bolts, and then the front wheel is overturned above a vamp, and the rear wheel is rotated and lifted above the outer side of the heel.

The control part of the foot-controlled thin-sole sliding shoe also adopts a self-locking switch and a return spring, and the foot jumping can be carried out in the same action through the coordination of the components, so that the sliding working condition can be converted into the walking working condition and locked, and the walking working condition can be returned to the sliding working condition and locked. The specific operation process is that the foot is jumped for the first time, the movable part of the self-locking switch is pulled to the rear end of the self-locking switch and is locked at the rear end, so that the wheel position is locked at the walking working condition position, the front wheel is arranged above the vamp, and the rear wheel is arranged above the sole at the outer side of the heel; the self-locking switch is unlocked by the second jumping, the locking bolt and the wheel box are reset to the sliding working condition by the locking bolt reset spring and the front and rear wheel box reset spring, and the movable part is pulled back to the front end of the self-locking switch by the steel wire connected with the movable part and is locked by the front and rear wheel locking bolts.

The method provided by the invention utilizes the function of increasing the distance between the ankle and the tiptoe caused by the change of the intersection angle of the foot and the crus, the dance and sports industry is called as 'jumping foot', one action of the jumping foot is used for replacing two actions of pressing and rotating by the aid of a hand, and the jumping foot can finish the action of one jumping foot when the foot strides forwards and leaves the ground no matter walking or sliding, so that the method is very convenient and quick without stopping the actions of the jumping foot and occupying extra time; when the emergency condition occurs during sliding, the two feet can be jumped up and jumped simultaneously to be converted into a walking condition, and the speed is reduced by walking; the control members are configured to operate in a no-load condition so that jumping of the feet cannot occur when the sheave is loaded at ground contact.

When seeing a small run to catch up with a group of people who are to be transferred, punched cards, attended to work, and school, it is highly desirable to provide them with a new tool that strives to reduce their journey by even a few minutes.

The step skating shoe is suitable for people who are not conscious of walking postures and often need to go out by means of transfer vehicles.

The implementation method is a conversion process between two working conditions:

the sliding working condition is as follows: when the self-locking switch is released, the self-locking switchmovable parts 325 and 326 are positioned at the front end of the directional slide rod, the front wheel is reset to the low position by the front wheel low-position return spring 55 and is locked by the front wheellocking bolt group 74, and the rear wheel is reset to the low position behind the heel by the rear wheel box low-position return spring 6C and is locked by the rearwheel locking bolt 87.

Tension working condition: under the sliding working condition, the intersection angle of the foot and the shank is increased by rotating the foot around the ankle joint, thefoot hoop 30 on the ankle uses thepull rope 31 to pull thepull ring 323 on the self-locking switch 32 to the rear end of the directional slide rod, so that therear section 325 of the movable part of the self-locking switch is matched with thefixing part 324 of the self-locking switch, the self-locking switch is locked, namely, the one-time tensioning working condition is completed, meanwhile, as thepull ring 323 moves backwards, the rightwheel wire drawing 33 is tensioned, thereturn spring 744 of the front wheel locking bolt is compressed, the rear and front low-position locking bolts 740 and 742 of the front wheel box are pulled out from the front wheel low-position locking hole of the front wheel bracket, thefront wheel box 72 can be turned to the upper inner sides of the front andrear door frames 50 and 51 by continuing tensioning, and the left wheel and the right wheel are the same and are not repeated; after therear wheel wire 35 is tensioned, the rear wheelbox locking bolt 87 is pulled out, and then therear wheel box 80 rotates outwards around the rear wheel box bearing shaft until the rear wheel box upper bearing 84 rotates out of the rear wheel box limiting arc-shaped baffle 69 for limitation, and then the rear wheel box moves upwards to the rear wheel high position.

The walking condition is as follows: after the stretching working condition is finished, even if the intersection angle of the foot and the lower leg returns to be normal, thepull rope 31 returns to be loose, the self-locking switch is still locked at the high position, and the front wheel and the rear wheel are also locked at the high position, namely the walking working condition.

Returning to a working condition: in the walking mode, the self-locking switch can be unlocked by repeating the stretching action, thefront wheel 73 is pulled to the low position by the front wheel low-position return spring 55, therear wheel 81 is returned to the walking position by the rear wheel low-position return spring 6C, and the front wheel box rear and front low-position locking bolts 740 and 742 and the rear wheelbox locking bolt 87 are used for locking.

The motion that the foot rotated around the ankle joint and pulled self-locking switch need not to go on when any no load is exactly the foot off the ground, can be in the process of sliding or walking, and one foot is accomplished respectively, also can both feet accomplish simultaneously when two feet bounce, need not to stop to get off the processing, and is very convenient. Particularly, when the rapid sliding device is used for rapid sliding, the rapid sliding device can jump up immediately to be converted into a walking working condition in case of emergency, and the toes are used for landing, so that the landing impact force is reduced, and safety accidents are avoided.

Self-locking switch: the self-locking switch is a large-stroke self-locking switch, when themovable part 325 of the self-locking switch approaches to thefixed part 324, the outerlayer toothed bar 3252 is guided by the outerlayer toothed bar 3244, so that the outerlayer toothed bar 3252 smoothly enters thefixed part 324 of the self-locking switch from theouter layer gap 3245; because theinner layer teeth 3251 and theinner layer teeth 3241 are staggered by 5 degrees at this time, after the tooth tip of theinner layer teeth 3251 moves backwards to the tooth tip of theinner layer teeth 3241, and then the tooth tip of theouter layer teeth 3252 moves backwards to the tooth tip of the outerlayer teeth ethylene 3242, therear section 325 of the movable part of the self-locking switch inevitably rotates by 5 degrees anticlockwise along the induction of the conjunction of theinner layer teeth 3241 and theteeth 3251 and the movement backwards; when the pulling force of thepulling rope 31 disappears and is loose, and therear section 325 of the movable part of the self-locking switch moves forwards, the outerlayer tooth profile 3252 deviates from the 3245 gap by 5 degrees and is overlapped with the outer layer tooth profile B3242 by 5 degrees, so that the outerlayer tooth profile 3252 is guided along the outer layer tooth profile B3242 until the outerlayer tooth profile 3252 reaches the bottom of the outer layer tooth profile B3242, and the self-locking switch is locked. When therear section 325 of the movable part of the self-locking switch moves backwards again, the inner layer teeth penta 3251 move backwards to the bottom of theinner layer teeth 3241, the inner layer teeth rotate anticlockwise by 5 degrees, the outerlayer teeth hex 3252 are overlapped with the outerlayer teeth xy 3243 by 5 degrees when the outerlayer teeth hex 3252 move forwards back, the forward movement is continued to be necessarily guided along the outerlayer teeth xy 3243 until the outerlayer teeth hex 3252 reach the outerlayer teeth notch 3245, themovable parts 325 and 326 of the self-locking switch are separated from the limit of thefixed part 324 of the self-locking switch at the moment, the movable parts return to the foremost end of thedirectional sliding rod 321, the front wheels and the rear wheels are reset to sliding states and locked, and the self-locking switch completes one cycle.
