Description

Shoes with resilient soles

The utility model relates to a kind of elastic force walking-aid footwear.

When the people walks, a pin step whenever advanced in years is all experienced and pedals ground (driving), strides and contact to earth (braking) three phases, the impulse force that produces when pin contacts to earth is 1.2～1.5 times (seeing " sport biomechanics ", People's Sports Press) of health gravity, it is the power that hinders when advancing, and easily fatigue damage is caused in joint and muscle.Do not have also at present both at home and abroad that the impulse force that obstruction can be advanced is controllable to change product and the document introduction that helps the power of advancing into, the external product that a kind of footwear that are referred to as to jump are only arranged, its function are to slow down the fatigue damage that impulse force causes joint and muscle and carry out recreation.

The purpose of this utility model is that a kind of impulse force that will hinder walking of design changes the thrust of advancing into, has obvious saving physical demands, obviously accelerates gait of march and avoid impulse force that joint and muscle are caused elastic force walking-aid footwear these functions of fatigue damage, practicality.When its radical change people walks, be with the present situation of very most of physical consumption on the deboost phase.

The utility model by last seesaw, rigidity go to the bottom, two groups of flexible members, two groups of ratchets and tooth bar, back-moving spring and bearing pin form, last seesaw can be fixed on the pin, two groups of flexible member fore-and-aft directions are arranged, and be installed in respectively between seesaw and rigidity go to the bottom, on two groups of ratchets and tooth bar are installed in seesaw respectively and go to the bottom.

The seesaw of going up of the present utility model is incorporated with footwear, or is combined into one with shoe-shaped pattern and restraint zone.

Flexible member of the present utility model can be that elastomeric material is made; also can make by gas and rubber bag tank; center of effort's line of back group flexible member preferably is positioned at apart from the scope of 1 centimetre to 4 centimetres of aforesaid shoe-shaped pattern or footwear rearward end, and center of effort's line of preceding group of flexible member preferably is positioned at apart from the scope of 2 centimetres to 5 centimetres of the leading sections of aforesaid shoe-shaped pattern or footwear.

Two groups of ratchets of the present utility model and tooth bar, one group of ratchet and tooth bar are installed in the rear portion, its center of effort's line is preferably organized flexible member center of effort line with the back and is overlapped, and another group is installed in the middle part, and its center of effort's line preferably is positioned at the mid point of two groups of flexible member center of effort lines.

Rigidity of the present utility model go to the bottom and the periphery of last seesaw between the material of available softness connect, rigidity is gone to the bottom and can be stained with one deck rubber.

The utility model is through on the pin, or is fixed on the pin.Contact to earth the stage, the impulse force that pin provides makes its distortion by last seesaw compressing back group flexible member, and when impulse force reached maximum, back group ratchet and tooth bar clamping were lived, thereby made back group flexible member keep being out of shape accordingly with the impulse force maximum.Along with stage of contacting to earth of pin to the driving phase transition, the distortion of preceding group flexible member strengthens gradually, during a certain value in its suffered power reaches 80～100% scopes of the suffered power of back group flexible member (this value is relevant with the position that the speed of travel and pin are fixed on last seesaw), back group ratchet and tooth bar are thrown off, and middle part group ratchet and tooth bar clamping are lived, the elastic restoring force of back group flexible member, by being the last seesaw of fulcrum with the middle groups ratchet, the distortion of group flexible member continues to strengthen before making, when the distortion of back group spring element recovers 50%, middle groups ratchet and tooth bar are thrown off, the elastic restoring force (maximum can reach 1.3～1.5 times of maximum impulse force) of preceding group flexible member all acts on the forefoot, promotes health and advances.Through above operation program, half of walking impulse force is transformed into the motive force of advancing.Above process constantly repeats to finish when walking.

The utlity model has following characteristics: when having realized walking, the impulse force that pin contacts to earth changes the motive force of advancing into, and the physical consumption when obviously having reduced walking can make gait of march obviously improve, and can reduce or avoid the fatigue damage of impulse force to joint and muscle.
