A ground contact member 300, which will be described later, And a base strap member 400, which will be described later, is movably coupled along the longitudinal direction. In addition, it may be manufactured in the form of a hollow pipe of a lightweight metal material or a synthetic resin material to reduce weight, and may be manufactured in a multistage manner so as to facilitate length control and portability though it is not shown in the drawing. Further, for the purpose of fixing the base strap member 400 to be described later, the holding bar magnetic force member 110 may be movably coupled in the vertical direction.

4 to 7, the handle 200 is fixedly coupled to the upper end of the support bar 100 so as to be grasable by the user, and has a 'T' shape or an 'I' shape for improving grip feeling, A soft material such as rubber, silicone or urethane may be bonded to the surface. And a strap for use to prevent it from being dislodged from the user's hand can be combined.

4, 6 and 13, the ground contact member 300 is fixedly coupled to the lower end of the strut 100 so as to support the walking of the user together with the strut 100 in contact with the ground And the buffer feet 310 of the plurality of soft materials are respectively coupled to the lower surface while spreading downward so that the ground contact surface widens. The reason for providing the cushioning foot 310 is that the cushioning foot 310 does not easily fall down while maintaining the standing state even when the wand is detached from the user's hand, Thereby imparting a non-slip effect. In addition, when the cane falls down in a side cross-sectional shape widening toward the downward direction, the user can easily raise the cane by stepping on the lower end of the upwardly directed side without bending the upper body.

4 to 8, 10, 11 and 12, the foot strap member 400 is movably coupled in the vertical direction of the support rod 100, It is a means for supporting the ankle or the calf portion of the foot requiring the attachment / detachment of the shoe so that the user can easily raise the ankle or the calf portion while fixing the ankle or the calf portion. For this, a strap bracket 410, a bracket interrupter 420, a strap swing plate 430, an elastic strap 440, and a handle strap 450 are included.

Specifically, the strap bracket 410 is a bracket that is movably coupled in the up and down direction of the support rod 100, and is a bracket between the support strap 400 and the support rod 100 So that the joining position can be adjusted.

As shown in FIG. 11, the bracket intermittent device 420 is a means for interrupting the up and down movement of the strap bracket 410, And may be rotatably coupled to a screw hole formed in the strap bracket 410 so that movement of the strap bracket 410 is interrupted.

The strap rotation plate 430 is rotatably coupled to the strap bracket 410 through a connection pin 431. A plurality of engagement holes 433 are vertically partitioned from the support rod 100, The formed latching plate 432 is integrally formed. The reason why the strap bracket 410 is rotatably coupled to the strap bracket 410 is that when the user lifts the foot requiring the attachment / detachment of the foot on the knee of the opposite leg as shown in FIGS. 16 and 17, Or the calf portion is wrapped with the elastic strap 440 to be described later, and when the user lifts the leg portion of the legs on the knee of the leg opposite to the leg, the user does not bend the body seriously forward, The strap rotation plate 430 is rotatably coupled to the strap bracket 410 together with the elastic strap 440 so as to hold the handle strap 450 or the grip strap 450 to be described later. The reason why the plurality of latching holes 433 are formed so as to pass through the latching plate 432 in the upper and lower portions is that the latching plate 432 has hooks 432 coupled to the elastic straps 440 along different ankles or calf circumferences 442 are caught by any one of the locking holes 433.

One end of the elastic strap 440 is fixedly coupled to the strap rotation plate 430. The elastic strap 440 is bent in one direction so as to wrap the ankle or the calf portion of the user with a spring force in response to an external impact, And a hook 442 engaging with the latching hole 433 is fixedly coupled to the other side of the leaf spring 441 so that the bent state of the leaf spring is fixed. As shown in FIG. 8, the leaf spring 441 is a spring which protrudes upward in a bending direction in a straight state, and is bent while being curled by a spring force when an impact is applied to a convex portion. In the present invention, The ankle or shank is used to wrap an ankle or a calf portion by applying a shock to the convex portion of the leaf spring. Thus, the user can easily perform the operation without surrounding the ankle or the calf portion with a wire or a band. The plate spring 441 is not shown in the figure but can be covered by a cover having a buffering and anti-slip function without being disturbed by the spring force.

That is, when the user holds the support rod 100 or the strap 450 in a state where the ankle or the calf portion of the user is wrapped around the knee, the user is prevented from slipping due to slippery clothes and vertical load when the user lifts the support rod 100 or the knot strap 450 over the knee of the other leg. At this time, a cover formed by protruding each of the friction protrusions 443 may be covered on the surface of the leaf spring 441.

8 and 12, the hooks 442 of the elastic straps 440 are engaged with the hooking holes 433 so that the hooks 442 are hooked on the ends of the hooks 444 so as not to be easily separated from external impacts, . The elastic strap 440 surrounds the user's ankle or calf portion by the spring force of the elastic strap 440 and the hook 442 formed with the hook barb 444 is engaged with the hooking hole 432 of the latching plate 432, The user can hold the support rod 100 or the handle strap 450, which will be described later, to easily lift the foot requiring the shoe removal on the knee of the opposite leg. At this time, even if the hooks 442 are not completely caught in the hooking hole 433 of the latching plate 432 during the bending of the elastic strap 440 around the user's ankle or calf, So that the user can easily grip the hook 442 that is moved forward of the ankle or shin and hold the hook 442 in the hook hole.

The handle strap 450 is fixedly coupled to the strap bracket 410 so as to be easily pulled up by pulling the elastic strap 440 in a state in which the user's ankle or calf portion is wrapped. In other words, in the state where the user's ankle or calf portion is wrapped with the elastic strap 440, the user can hold either one of the support rod 100 or the pull string 450, or both at the same time, .

8 and 13, a strap magnetic force body 460 is fixedly coupled to a rear surface of the elastic strap 440, and the strut 100 is fixed to the elastic strap 440. [ The magnet member 110 may be movably coupled to a position facing the strap magnetic force body 460 so that the magnet member 440 is magnetically coupled while maintaining a straight state. That is, when the user uses the elastic strap 440 of the bottom strap member 400, the elastic strap 400 is straightened and the strap magnetic force body 460 and the holding bar magnetic force body 110 are magnetically So that the elastic strap 400 can be maintained in a straight state.
