Description

A retractable crutch

technical field

The utility model relates to a crutch, in particular to a retractable crutch.

Background technique

Crutches are an important medical rehabilitation aid, suitable for the elderly, the disabled and many other people with limited mobility.

Existing patent application number is the utility model patent of CN93218606.8, and this patent announcement date is May 11th, 1994, and the patent title is: a kind of novel crutch. The application includes the upper part of the crutch body, the armrest, and the lower part of the crutch body with adjustable length. The upper part of the crutch body and the extension line of the lower part are inclined backward at an acute angle of about 10°. The ring has a nylon buckle, which can be sealed on the forearm; the armrest is perpendicular to the crutch body, a glyph steel bar is arranged in the connecting part of the armrest and the crutch body, and a rubber cap is arranged at the lower end of the telescopic crutch body. The crutch can be fastened on the forearm through a nylon buckle, which has the function of auxiliary support for the human body and has a higher safety factor. However, just because the nylon buckle is arranged on the upper part of the crutch body, the length of the crutch is longer, which increases the footprint of the crutch, which is not conducive to storage and reduces portability.

detailed description

In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments.

Example

Referring to Figures 1 and 2, a stowable crutch in this embodiment includes a retractable stick body 4, an arm handle 2, and a handle 3 whose one end is hinged to the stick body 4 and the other end is hinged to the arm handle 2, specifically , as shown in Figure 3, the stick body 4 of the present embodiment adopts a three-stage telescopic rod, the top of the stick body 4 is provided with a connecting handle 41, and one end of the connecting handle 41 is threadedly matched with the stick body 4, and the stick body 4 is connected to the A connecting handle fixing ring 42 is provided between the handles 41 to limit the screwing position of the connecting handle 41 on the rod body 4. The other end of the connecting handle 41 and one end of the handle 3 are hinged at the first hinge point 32, and the other end of the handle 3 is connected to the first hinge point 32. The arm handle 2 is hinged at the second hinge point 34; the arm handle 2 is provided with an arm ring 1, and the axis of the arm ring 1 is parallel to the arm handle 2; the handle 3 is provided with a handle 31, and the handle 31 is perpendicular to the handle 3; the handle 3 and The hinge of the stick body 4 is provided with a handle limiting mechanism 33 capable of limiting the position of the handle 31 in use, and the hinge of the handle 3 and arm handle 2 is provided with an arm handle capable of limiting the position of the armband 1 in use. The limit mechanism 35, and when the retractable crutch is in use, the arm ring 1 is located directly above the handle 31. It should be explained that when the crutches are in use, the angle between the handle 31 and the stick body 4 is approximately 90 degrees, preferably slightly greater than 90 degrees; the center line of the armband 1 is approximately perpendicular to the handle 31, as shown in Figure 2 shown.

Both the handle limiting mechanism 33 and the arm lever limiting mechanism 35 of this embodiment adopt a spring lock pin mechanism. Now take the handle limiting mechanism 33 as an example to illustrate with reference to FIG. 4 . One end of the handle 3 hinged with the connecting handle 41 is provided with an accommodating chamber 36 to accommodate a lock pin 332, and a spring 331 in a compressed state is provided between the bottom of the lock pin 332 and the bottom of the accommodating chamber 36. When the crutch is in use, The head of the locking pin 332 stretches out of the accommodating cavity 36 and is inserted into the socket provided on the side wall of the connecting handle 41, then the locking pin 332 and the first hinge point 32 realize two points between the handle 3 and the connecting handle 41. Type positioning, the position of the handle 3 is fixed. The structural principle of the arm limit mechanism 35 is the same as that of the above-mentioned handle limit mechanism 33 . Provided here is only a preferred limit mechanism, and the mechanism that can limit the mutual rotation position of the two hinged rods is very common, such as ball spring type limit, or directly adopt the latch to replace the above-mentioned spring lock pin mechanism, here I won't repeat them one by one.

As shown in FIG. 1 and FIG. 5 , a notch 11 is provided on the side of the arm ring 1 , and when the arm handle 2 and the handle 3 are folded, the notch 11 allows the arm ring 1 to pass through the stick body 4 , and the folding effect is better.

As shown in Figure 2, the bottom of the stick body 4 of this embodiment is provided with a base 6, the base 6 is narrow at the top and wide at the bottom, preferably rubber, with good gripping effect and high safety factor. Specifically, a threaded rod 5 is provided between the rod body 4 and the base 6, and the rod body 4 and the base 6 are threadedly connected with the two ends of the threaded rod 5 respectively. The rod limit ring 44 at the screwed position of the threaded rod 5 is provided with a base limit ring 51 that limits the screwed position of the base 6 on the threaded rod 5 at the bottom of the threaded rod 5 .

In order to better understand the stowable crutch of this embodiment, the use state and folded state of this embodiment will be briefly described with reference to FIGS. 1 to 5 . As shown in Figure 1, when using the crutch, pass the hand through the arm ring 1 from top to bottom, and hold the handle 31. At this time, the arm ring 1 covers the user's arm; when the crutch needs to be put away, As shown in Figure 5, loosen the stick body limit ring 44 and the base limit ring 51, adjust the base 6 to the bottom of the stick body 4 closest to it, then shrink the stick body 4 to the shortest, and then press the lock pin with your fingers 332, then the lock pin 332 is disengaged from the jack on the connecting handle 41, and the handle 3 is rotated to be perpendicular to the stick body 4. Similarly, the arm handle 2 is rotated to be perpendicular to the handle 3. At this time, the handle 31 is in the position of the handle 3. 2 and the stick body 4, and the arm ring 1 passes through the stick body 4. At this time, the crutch shrinks to a minimum.

The utility model relates to a stowable crutch. The body of the crutch is retractable, and the handle and arm handle can be rotated and folded, which greatly reduces the space occupied by the crutch and greatly improves portability.

The above has schematically described the utility model and its implementation, which is not restrictive, and what is shown in the drawings is only one of the implementation of the utility model, and the actual structure is not limited thereto. Therefore, if a person of ordinary skill in the art is inspired by it, without departing from the purpose of the utility model, without creatively designing a structural method and embodiment similar to the technical solution, all should belong to the utility model protected range.
