Detailed description of the invention

Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.

As shown in Figure 1, a kind of walking aid, comprise the leg member 1 being fixed to thigh position and the little leg member 2 being fixed to shank position, described leg member 1 and described little leg member 2 are telescopic member, the lower end of described leg member 1 is by the rotating upper end being connected to described little leg member 2 of hinge 3, and both form a compliant mechanism matched with human leg's physiological structure.Because walking aid total forms the compliant mechanism matched with human leg's physiological structure, therefore in the process using walking aid walking, leg can not be subject to the resistance from walking aid and feel uncomfortable.

As shown in Figures 2 and 3, described leg member 1 comprises thigh stationary pipes 4, thigh support bar 5, thigh energy storage spring 6 and end cap of the spring 7, described end cap of the spring 7 is fixed on the top of described thigh stationary pipes 4, and the bottom of described end cap of the spring 7 extends to the top in described thigh stationary pipes 4.The top of described thigh support bar 5 is in the bottom in described thigh stationary pipes 4, is provided with spring fastenings 8 at the top of described thigh support bar 5.Described thigh energy storage spring 6 is in the centre position in described thigh stationary pipes 4, and its upper end is enclosed within the bottom of described end cap of the spring 7, and its lower end is enclosed within the top of described spring fastenings 8.

The large leg restraint gear 10 be fixed to by described leg member 1 on thigh is provided with outside the upper end of described end cap of the spring 7, described large leg restraint gear 11 comprises fixed block 12 and back-up block 13, one end of described fixed block 12 and the upper end thereof of described end cap of the spring 7, described back-up block 13 is slidably on described fixed block 12, and described back-up block 13 is also provided with the arc groove matched with thigh.When walking aid does not use, rotate fixed mechanism 11 to the position overlapping with leg member 1, the space that walking aid occupies can be reduced, be convenient for carrying.When using walking aid, rotate fixed mechanism 11 to the position vertical with leg member 1, then according to individual practical situation, back-up block 13 is slided into suitable position, the arc groove on the back-up block 13 made is enclosed within thigh just can.As shown in figs. 1 and 6, the fixed block 20 be fixed on shank is provided with outside the middle part of described shank stationary pipes 14, described fixed block 20 is also provided with the arc groove matched with shank, arc groove on back-up block 13 is enclosed within thigh, and corresponding is enclosed within the arc groove on fixed block 20 on shank.

As shown in Fig. 2,4 and 5, described little leg member 2 comprises the shank stationary pipes 14, shank support bar 15, shank return spring 16 and the contact 17 that are fixed to shank position, described shank support bar 15 runs through described shank stationary pipes 14, and the two ends up and down of described shank support bar 15 are all extended outside described shank stationary pipes 14, the lower end of described thigh support bar 5 is connected to the upper end of described shank support bar 15 by described hinge 3, be connected with described contact 17 in the lower end of described shank support bar 14.Bottom in described shank stationary pipes 14 is provided with spring pullover 18, described spring pullover 18 is enclosed within the outside of described shank support bar 15, the position being in corresponding described spring pullover 18 in described shank stationary pipes 14 at described shank support bar 15 is provided with step 19, and the upper and lower side of described shank return spring 16 props up this step and described spring pullover 18 respectively.

Foot is upwards lifted and foot two kinds of situations of going down the hill downwards to step on are analyzed walking aid respectively and how to be realized playing buffering to leg knee joint and alleviating leg burden below by going up a hill in hill climbing process:

When going up a hill, a legs and feet palm upwards lifts and is cross over single order step forward, and this lower limb is by stretching shape by knee joint bending, and and then another lower limb is stretched and is also moved upwards up to single order step, and namely the rising completing ladder climbs the mountain.In the process of making above-mentioned action, center of gravity concentrate be in a step at first lower limb on namely bending at first lower limb, the thigh of this this lower limb can press down under the effect at self gravitation near the position of buttocks, will drop-down large leg restraint gear 10, thus compression thigh energy storage spring 6, in the process that thigh energy storage spring 6 compresses, on the one hand buffer memory is carried out to leg knee joint; Support a part of weight of self in addition on the one hand, alleviate leg burden.A part of weight passes to shank support bar 15 by thigh support bar 5 and hinge 3 in addition, shank support bar 15 presses down shank support spring 16, the contact 17 made withstands ground, thus gives ground by other a part of weight transmitting, greatly alleviates the weight that this lower limb bears.And then the lower limb being in a step is at first had an effect from bending becoming and is stretched, and drives the lower limb on next stage rank upwards to lift and moves to single order step.Along with this action, thigh energy storage spring 6 and shank return spring 16 can lose the gravity of human body self to it gradually, from compressive state can revert to original state, in restorable process can support human body move upward to kneed a part of weight, also mitigate the burden of leg.Constantly replace according to above-mentioned change, walking aid can the stressed leg knee joint of continuous change protection and alleviate the burden of stressed leg, goes up a hill until complete.

When going down the hill, a lower limb stretches next stage rank of stepping on, and another lower limb is bending rests on former step.In the process down stepped on, center of gravity concentrates on the lower limb being in and namely the lower limb of former step bends, can obtain according to above-mentioned analysis, leg curvature is with following stressed transmission: thigh can press down under the effect at self gravitation near the position of buttocks, will drop-down large leg restraint gear 10, thus compression thigh energy storage spring 6, in the process that thigh energy storage spring 6 compresses, on the one hand buffer memory is carried out to leg knee joint; Support a part of weight of self in addition on the one hand, alleviate leg burden.A part of weight passes to shank support bar 15 by thigh support bar 5 and hinge 3 in addition, shank support bar 15 presses down shank support spring 16, the contact 17 made withstands ground, thus by other a part of weight transmitting to ground, greatly alleviates the weight that leg bears.A lower limb is stepped on behind next stage rank; and then this lower limb bends to drive the lower limb on former stage rank to move down into next stage rank; in the process, center of gravity concentrates on the lower limb being in and namely the lower limb of next step bends, and same walking aid can protect the knee joint of this lower limb.Constantly replace according to above-mentioned change, walking aid also can leg knee joint that constantly change protection is stressed and alleviate the burden of stressed leg, until complete.

As shown in figs. 1 and 6, this walking aid also comprises by pulling the handle 9 compressing or uphold described thigh energy storage spring 6 up and down, the both sides of described thigh stationary pipes 4 are provided with the sliding tray 10 vertically arranged, and described handle 9 connects described thigh support bar 1 through this sliding tray 10.When going up a hill, can energy storage spring be pulled by upper lift hands 9, alleviating the resistance lifted foot-propelled and do further.When going down the hill, pressing down handle 9 can be applied directly to power on support bar and contact 17, alleviates the load-bearing burden of foot equally further.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
