Description

A kind of all-round caster walking aid

technical field

The invention relates to a rehabilitation training device, in particular to a walker with all-round casters.

Background technique

The frame-type walkers currently on the market for patient walking rehabilitation training and assisted walking for the elderly are mainly divided into three categories: four-legged wheelless type, four-legged wheeled type and two-legged wheeled type. The advantages and disadvantages of these three types of walkers are as follows:

The four-legged wheelless walker is not easy to slip due to the large resistance between the feet and the ground, and the patient is not easy to slip when walking with support, and the stability is good, but this kind of walker requires the patient to hold it It can only be moved forward by lifting it up. Considering that most of the users of the walker are patients or the elderly with weak lower limbs, this way of moving is too laborious and has certain safety hazards;

Although the four-legged wheeled walker makes it easier for patients to use it, because the friction between the walker and the ground is very small, the patient will hold the walker to move forward, especially uphill or downhill. , once the body leans forward or backward, it will slip and wrestle;

Although the two-legged wheeled walker makes up for the shortcomings of the previous two walkers to a certain extent, it also weakens the advantages of the previous two walkers from another perspective, that is to say, the two-legged walker Wheel-type walkers are not as stable as four-legged wheelless walkers, and less flexible than four-legged wheeled walkers.

Sleeve 501 is welded on the outside of the support frame. The upper half of the sleeve 501 is cylindrical, the lower half is truncated circular, and the bottom end is provided with a rubber anti-skid sleeve.

The spring 502 is arranged inside the casing 501 , and the upper and lower ends of the spring 502 are respectively fixed on the soles of the feet of the first support frame 101 and the second support frame 102 and the upper end of the leg rod 503 .

The leg rod 503 is disposed in the inner hole of the spring 502 .

The axle 504 is located at the other end of the leg rod 503 .

Auxiliary walking wheel 505 is located on the wheel shaft 504,

The wheel shaft 504 abuts against the spring 502 , and the leg rod 503 is telescopically arranged in the inner hole of the spring 502 , so that the auxiliary walking wheel 505 can expand and contract relative to the casing 501 .

Fig. 4 is a structural schematic diagram of the locking device of the weight loss training frame in the embodiment of the present invention.

As shown in Figure 1, Figure 2 and Figure 4, the weight loss training frame 6 is connected with two soft suspension ropes 7, including a left training frame 601, a right training frame 602 and a locking device 8, a left training frame 601 and a right The training frame 602 is respectively fixed on the left crossbeam 2 and the right crossbeam 3 through the locking device 8 , and the locking device 8 includes: a rotating handle 801 , an upper crossbeam clamp 802 and a lower crossbeam clamp 803 .

One of the left training frame 601 and the right training frame 602 is provided with a groove, and the other is provided with a boss corresponding to the groove, and the left training frame 601 and the right training frame 602 are connected through the groove and the boss.

The rotating handle 801 is located at the lower ends of the left training frame 601 and the right training frame 602, and is provided with an internal thread, which is matched with the external threads of the left training frame 601 and the right training frame 602 lower ends.

The working process of the all-round caster walker of this embodiment is as follows:

In the all-round caster walker 100 of this embodiment, when the patient holds the first support frame 101 and the second support frame 102 with both hands and presses down to move, the auxiliary walking wheel 505 is retracted into the casing 501 by the spring 502, so that The casing 501 is grounded, forming a four-corner wheelless walking aid. When the patient maintains a standing posture and pushes the walker forward, the longitudinal force exerted on the walker decreases, and the auxiliary walking wheel 505 extends out of the sleeve 501 through the spring 502 to form a four-legged wheeled walker . The walker can be used as a chair when the cushion 9 is laid flat, and it can be folded and placed when being used for walking.

Function and effect of embodiment

The all-round caster walker of this embodiment has an all-round caster mechanism with an automatic locking function, so when the patient is performing walking rehabilitation training to push the walker forward, he only needs to push it lightly instead of lifting the walker , and it is more labor-saving and more flexible when pushing the walker. Because of the detachable weight loss training frame, patients can choose to carry out normal walking rehabilitation training or weight loss suspension walking rehabilitation training according to their own recovery period and rehabilitation environment, which also makes the walking aid more convenient to transport and store . Because of the foldable cushion, patients can sit and rest anytime and anywhere.

The all-round walker with casters in this embodiment, because the rubber anti-slip sleeve under the casing has a relatively large frictional force with the ground, it has good anti-slip performance and is safer for patients when walking.

The all-round walker with casters of this embodiment is more flexible and convenient for patients to use because the weight loss training frame is detachable.

The above embodiments are preferred cases of the present invention, and are not intended to limit the protection scope of the present invention.
