Description

A dual-purpose walking aid

technical field

The utility model relates to a walking aid tool, in particular to a dual-purpose walking aid frame for assisting people with weak legs and feet to walk.

Background technique

The function of the walking frame is to maintain the balance of the standing body, support the body weight, train walking, and enhance muscle strength. The walking frame is supported by both hands to help support the body and reduce the burden on the feet, so that it can assist people with weak legs and feet to walk slowly.

The current walking frames are generally four-legged, and there are also two-legged supports. The two-legged walking frame is difficult to balance and support, and it cannot provide enough support for people with weak legs and feet. Generally, the left and right sides of the four-legged walker frame can be intermittently landed separately, while the front foot and the rear foot on one side are at a fixed distance, and the distance is greater than the width of a staircase. Therefore, it can only be used on flat ground, and becomes a cumbersome burden when going up and down stairs, which is very inconvenient to use. Therefore, the current walking aids are either complex in structure and operation, have strong limitations in use scenarios, are not easy to store and move, or are not well combined with aiding stairs and walking.

Detailed ways

The specific embodiment of the utility model will be further described below in conjunction with the accompanying drawings.

As shown in Fig. 1, Fig. 2 and Fig. 3, a dual-purpose walking frame of the present invention includes a tubular main support frame 11 with two front support feet 12 and a handle 13, and two rear supports The tripod 21 of the foot 22, two connecting rods 31 hinged to the front support foot 12 and the rear support foot 22 at both ends, and an auxiliary sleeve 15 fixedly attached to the front support foot 12 and provided with a chute (not shown in the figure) , a slider (not shown) fixedly connected to the rear supporting foot 22 and embedded in the chute, a positioning hole (not shown) provided at the bottom of the chute of the auxiliary sleeve 15, and The snap buckle fitted on the rear supporting leg 22 and snapped into the positioning hole, and the spring 18 arranged in the auxiliary casing 15 drives the stand 21 to fold upward. The walking aid articulates the front supporting foot 12 and the rear supporting foot 22 through the two ends of the connecting rod 31, and the rear supporting foot 22 is slidably connected with the chute attached to the front supporting foot 12 through a slider, so that the walking aid supports the supporting foot 22 after unfolding. Switch between the two states of the back support pin 22 and the retracted one. It is locked in the unfolded state by the snap buckle, so as to provide a larger support area, better support the user, and facilitate use on flat ground. Untie the buckle spring and push the foot frame 21 to pack up so that the distance between the front and rear supporting legs is reduced, that is, the folding of the walking aid makes the front and rear of the walking aid narrow, so that it can be used as a walking aid for assisting up and down stairs. Tilt the walker frame slightly backwards, and slowly push out the main support frame 11 and its front support legs 12 with the rear support feet 22 on the ground.
