In the following, an example of the use of impact relief walking aid according to an embodiment of the present specification will be described with reference to the accompanying drawings.

1 to 4, formed in the shoe fixing band 31, the ankle fixing band 35, the long-term fixing band 34 and the thigh fixing band 33 mounted on the above-described footrest 13 One fastener (referred to as an example of a jaw-shaped fastener) is connected to the other fastener (14 as an example) formed in the ankle joint link 14 or 15, the leg support 16 or 17, and the knee joint link 18 or 19. , 凸 type fasteners).

Therefore, the wearer's shoes, ankles, short and thighs are accommodated in the footrest portion 13, ankle fixing frame 36, long and short fixing frame 25 and thigh fixing frame 27.

As described above, the shoe fixing band 31, the ankle fixing band 35 and the short and short fixing band 34 and thigh fixing band 33 of the male and female fasteners corresponding to each other to fix the footrest portion ( 13), the leg support (16, 17) and the knee joint link (18, 19) it is possible to fix the wearer's shoes, legs and knee areas.

As shown in FIG. 3, when the patients with weak knee joint function or muscle strength due to injury to the knee area walk after wearing the walking aid A for rehabilitation treatment or training purposes, the ankle joint links 14 and 15 The U-shaped foot drooping prevention device 32 fixed at an arbitrary position prevents foot drop, and the wearer's forefoot is lifted so that the heel contacts the ground first.

Therefore, it is possible to prevent the twisting of the fixed foot to be rehabilitated during walking can reduce the fatigue caused by the use of walking aids for a long time, and the heel first touches the ground, so it helps to maintain normal walking and help to walk normally do.

In addition, when walking the elastic force of the buffer spring 24 (compression coil spring is used to act as a damping) mounted between the upper side of the side plate 12 of the footrest portion 13 and the lower end of the ankle joint link (14, 15) By transmitting the shock transmitted through the footrest portion 13 from the ground to the leg support (16, 17) to alleviate it can be minimized to be transmitted to the wearer's leg or knee joint.

As shown in FIG. 4, when the patient wearing the walking aid A climbs or descends the stairs, or when the knee is bent to sit on a chair, the knee joint guide port 23 assists the bending and extension of the knee. You can do it.

That is, the ankle support and the short and fastened by the ankle support 20 and the short-term stopper 21 fixed to the leg support (16, 17), and fixed to the thigh support (22) fixed to the knee joint links (18, 19) The gas spring 28 in which the head side is fixed to the thigh fixing frame 27 and the rod side is fixed to the connecting bracket 29 of the leg supports 16 and 17 in accordance with the knees bent while being fixed and fixed by the thigh. This shrinkage deformation.

That is, since the body load of the wearer is transmitted to the gas spring 28 which is deformed and deformed, the wearer may bend the knee slowly.

At the same time, the first elastic member 26 (an example, a tensile coil spring is used) and the short end fixing frame 25 having the upper end fixed to the short and long fixing frame 27 and the lower end fixed to the connecting bracket 29 are used. The second elastic member 30 (for example, an elastic strap is used), which is fixed at the upper end and fixed at the lower end to the connecting bracket 29, is subjected to a tensile force.

At this time, the connecting bracket 29 which is rotatably fixed to the leg supports 16 and 17 by the fixing pin P4 is rotated counterclockwise in the drawing with the fixing pin P4 as the central axis.

When the wearer bends the knee a little further, the gas spring 28 shrinks within the arbitrary stroke range. That is, the contraction deformation of the gas spring 28 within the tensile force of the second elastic member 30 is limited.

As described above, when the patient who is uncomfortable with the knee bends the knee while wearing the walking aid A, the knee joint link 18 pivotally connected to the upper end of the leg supports 16 and 17 by the knee joint guide port 23. (19) is rotated counterclockwise on the drawing with the fixing pin (P3) as the central axis, it is possible to bend the knee joint by bending the thigh with respect to the leg.

At this time, the body load transmitted through the thigh of the wearer is absorbed by the gas spring 28 and transmitted to the leg supports 16 and 17, so that the knee joint can be bent in a stable state.

On the other hand, when the wearer rises up the thigh to extend the bent knee, the gas spring 28 is deformed by the elastic restoring force of the first elastic member 26 (tension coil spring). That is, as the gas spring 28 is deformed, the knee joint links 18 and 19 are rotated in the clockwise direction with respect to the leg supports 16 and 17 so that the knee joints can be unfolded.

As described above, by repeatedly rotating the knee joint links 18 and 19 with respect to the leg supports 16 and 17 by the repetitive expansion and contraction of the gas spring 28, the wearer alone bends or extends the knee joint. Can be repeated.

Therefore, the walking aid can be usefully used for rehabilitation treatment so that patients with weakened knee joints or muscles can walk normally.

Herein, while the foregoing specification has been described with reference to the preferred embodiments, those skilled in the art may variously modify and modify the present disclosure without departing from the spirit and scope of the present disclosure as set forth in the claims below. You will understand that you can change it.
