Description

The utility model relates to devices (the so-called "walkers") that help people with disabilities to move, and can be used to independently move such people.

Known walkers are described in document CN 101385684 (IPC A61H 3/00; A61N 2/08, published on March 18, 2009), including: a support frame, a handrail, a telescopic crossbeam, a transverse rod, a magnet, a telescopic support, a hinge, a connecting buckle and folding rod in the middle of the walker; telescopic walker support can be used to arbitrarily adjust the height and lateral size of the walker.

The disadvantages of the known walkers include equipping the device with a single tool, without the ability to remove or replace it, in addition, in the area of the handles on which the person relies when using the walker, there is a magnet that has a harmful effect on the user's hands.

Known walkers (CN 206044939, IPC A61H 3/00, published March 29, 2017) containing a telescopic support, in the lower part provided with a rod, with locking of intermediate positions provided by the latch, and the lower edge of the support is equipped with fixed support wheels, and the walkers have support legs that are equipped with button holes. The bottom of each button is connected to the internal spring of the support, the spring is installed in a cylindrical pipe, and the side of the supports of the fixed mechanism is equipped with six holes for the buttons, the diameter of the holes for the buttons is the same, the buttons are located on one straight line. The device allows you to adjust the fit for the growth of the user, can be folded.

The disadvantages of this model include:

- difficulty in the manufacture and installation of push-button clamps, which tend to jam in the pipe in which they are installed,

- supporting legs have only six levels of height adjustment, covering a small range of height adjustment for the height of the patient (user).

The technical problem solved by the utility model is to expand the functionality of the device (walker) for people with disabilities in motion.

The technical result is the use of walkers (in addition to direct use as a means to facilitate movement) also as a chair-chair.

The problem is solved, and the technical result is achieved by walkers containing two curved handrails with jumpers, handles are installed on the horizontal sections of the handrails, the jumpers being connected to the handrails by traction rivets with the formation of a rigid connection, and the handrails are pivotally connected to the welded crossbar and a folding jumper, while the handrails are connected and the crossbar is hinged - type “pipe in pipe”, with the fixation of the position of the crossbar in height due to the sleeve installed on each of the handrails, limiting vertical movement of the crossbar, with the bushings fixed by traction rivets on the handrails, and the connection of the handrails to the folding jumper is a structure of pipes intersecting at different levels, and at the pipe joints there are through holes through which the bolt connection passes with a set of connecting plastic bushings, providing on one side a fixed connection vertically, and on the other hand - free rotation of the pipes in the axis of the bolt connection, while the folding bridge has a telescope the pipe is designed in a pipe with a clamp of the extreme unfolded position, and for fixing the fabric seat at the bottom of each of the vertical pipes of the welded beam, brackets with a hole and a hook are welded, and the walkers have a folding fabric seat, which is a dense fabric stretched between two pipes with fixing to them, moreover, one of the pipes is embedded and fixed in the holes provided for this in the arms of the crossbar, and the second is movable and mounted on the hooks of the handrail in the when it is in a nested state or nested in the hooks of the arms of the crossbar when folded. According to a utility model, the handles are located on two levels of the handrails.

If necessary, height-adjustable legs with soft anti-slip tips can be attached to the handrails at the bottom.

The essence of the utility model is illustrated by drawings, which show:

In FIG. 1 is a general view of the inventive walkers with an unfolded fabric seat;

In FIG. 2 - a) walkers in walking mode (with folded fabric seat); b) walkers in non-walking mode (unfolded fabric seat);

In FIG. 3 - shows the mechanism for adjusting the legs in height;

In FIG. 4 is a general view of a folding jumper;

In FIG. 5 is a diagram of the permutation of walkers when moving.

In the figures indicated:

1. Handrail

2. Folding jumper

3. Welded bar

4. Leg

5. pen

6. Handrail jumper

7. Bolted connection

8. Cloth seat

9. Handrail hook

10. Clip-on clips

11. Button on the leg of the walker

12. Movable pipe

13. Bracket

14. Button on folding jumper

15. Bushing

16. The pipe fixed in the holes in the arms of the crossbar 3

17. Holes in brackets 13

The inventive device operates as follows.

Initially, the walkers are in a folded state and they must be decomposed to the working state by unfolding the handrails 1 one after the other from the initial position, first in the direction opposite to the crossbar 3, and then in different directions. The use of walkers in walking mode is shown in FIG. 5 and represents a repeating sequence of actions, as a result of which the handrails 1 are alternately moved towards the movement necessary for the user. In this case, the handrails move parallel to each other with a slight displacement due to the geometry of the movable connection of the handrails 1 and the folding lintel 2. The step of the displacement of the handrails along the axis of movement depends on the height of the handrails, which can be variable and depends on the position of the legs 4 with height adjustment. Folding the walker is carried out in the following sequence: press the button 14 located on the folding jumper 2 and successively fold the inside of the handrail 1.

When used as a walker, the fabric seat 8 is in the folded state and, if necessary, can quickly be put into the unfolded state, which allows the use of the walker as a chair-chair (Fig. 1 and 2b). To do this, you just need to remove the movable pipe 12 from the hooks of the bracket 13 and put it in the hooks 9.

The advantages of the claimed utility model.

1. The use of a folding fabric seat 8 will allow the user at any time to use the walker as a chair-chair.

2. The use of legs 4 allows the user to adjust the height of the walker in increments of 25 mm, which makes it possible to more accurately adjust them to fit your height. Legs 4 have eight holes located in one line to adjust the structure in height. Height adjustment is carried out using the button 11 on the legs of the walker. To change the position, press button 11 on the leg of the walker, it is recessed into the hole in the outer pipe, then the outer pipe of the leg is shifted relative to the handrail pipe (the button remains recessed, because it rests against the pipe wall) to the following position until the leg is moved to the extreme provision providing the minimum dimensions of walkers. To facilitate the displacement of one pipe relative to another, bushings 15 are provided. The described actions are performed sequentially for all legs.

3. The design of the walker provides two modes of use: walking and not walking. The movement of the walker from one mode to another is carried out by rearranging the clip-clips 10. In walking mode, the clip-clips 10 should be located as shown in B. The translation of the walker in non-walking mode is carried out by moving the clip-clips 10 to the position as shown in view B1 (Fig. 2).
