Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for assisting people who have difficulty maintaining their balance while walking and for whom crutches are insufficient. This device is hereinafter referred to as a walker.

In reality, it is possible to change the length of the front and hind legs depending on the ground; one-legged walkers exist, especially for descending stairs. These devices are perfectly suited for balancing obstacles, supported entirely on four legs and supported by lateral excavations attached to two interconnected arched sections. These walkers have four oil-immersed telescopic guides, consisting of two independent elements, right and left, joined together by articulations, thus forming a collapsible support. Adjustment is made for each element on the right or left by levers that are repositioned under each grip of the support. When a hand is placed on each grip and the lever is raised, the oil circuit of each element on the right or left side is opened, and according to the pressure generated by the twisting, one leg rises and the other leg descends to become vertical. It can therefore be seen that this type of hydraulic walker is of interest in particular for stair climbing and for all areas. In reality, walkers have serious inconveniences that cause accidents. It is essential to actually twist the lever from the vertical (which causes the opening of the oil circuit to occur). By the way, the lever is in the hand that rests on the grip of the support for marching, and the hand instinctively clasps the whole thing, but the lever remains open, resulting in a descent due to imbalance.

The purpose of unfired IPl is to remedy these inconveniences.

Therefore, the present invention is designed to automatically set the 11.
In the event of a blockage or, conversely, a panic - Convulsions on the y dollar are related to those that tighten the handle tm beyond a certain point.

It is essential not to operate the cock of the hydraulic circuit while leaning on the walker at the shelter level, which was the case with the walker in the United States.

According to the invention, when a person operates the cock using the no-endoru and positions it one step ahead of the walker, or once the person moves to that position using another procedure, he/she supports himself/herself on the hand grip and moves the body while making any erroneous operation. Automatically release the handle to avoid this.

To do this, open the oil circuit (the handle is on the right side of the right handle and on the left side of the left handle. It is the thumb that pushes the handle, and since the thumb is on the outer 1./% handle side, the thumb must be moved back. It becomes extremely difficult for the user to grasp the grip of the support for walking, thus automatically blocking the circuit and blocking the skin of the walker. Turn the grip to grasp the grip and return the thumb to the inside 11411.

One variant designed to create safety is that if the user clasps the handle for movement and leaves his or her thumb on the handle, he or she will push the handle further, thereby occluding the circuit. .

Move the adjustment cock - The handle is attached to the tube near the front of the grip so that it is at thumb level.

The handle, which serves as a cock for opening, closing, and adjusting the hydraulic circuits of the right and left elements, is integrally formed with a stopper that is perforated along its diameter so that seventeen holes are located in the center line of the fluid conduit. The stopper is moved by the handle, and the handle can take three main positions, among which the blocked position is automatically recovered by a return spring, and the blockage of the hydraulic circuit blocks the telescope. do.

- Among the various postures of the steering wheel, S Tsutomu, which is tilted upward, is the first posture of the handle.
The return spring closes the hydraulic circuit, and as soon as the handle is released, it automatically returns to this position. The legs of the walker can be adjusted by applying slight pressure to the walker. A tilted downward position also blocks the hydraulic circuit and blocks the legs, and this position can cause the user to inadvertently place their thumbs on the handles It exists when you leave it on.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are shown by way of non-limiting illustrative example, will facilitate understanding of the invention. These represent preferred embodiments of the invention.

As seen in Figures 5 and 7, the walker has four oil-immersed telescopic guides 1.2, 3, 4 and two elements 5.6, one on the right and one on the left. These two independent elements 5.6 are articulated and thus form a total collapsible support.

Adjustment is made in each element by m 9 of the support of each element 6.5,
The handle 7.8 at the level of
It is done so that the dollar can be manipulated.

The left handle 7 is on the left side of the left grip 9, and the right handle 8 is on the right side of the right digger 10. Thus, when operating one of the handles, the user must move his thumb outward, on the same side as the other fingers, and as soon as he is about to grasp grip 9.10, he releases said handle 7 or 8 and uses grip 9, IO. Move your thumb inward to grasp it completely.

The handle 7 or 8 has a body 1, a plug 12 with a perforation along its diameter, the latter being housed within the body 10 such that its aperture 13 lies in the centerline X-Y of the fluid conduit. .

The spigot 12 is moved by the handle 7 and 8.

M; f) Jv'J In the case of A, the fluid conduit is closed. The horizontal position B opens the circuit and makes it possible to straighten the legs 1.2.3.4 of the walker by pressing lightly on the aisle 9. The released handle is returned to its initial position A by the spring 14, and this closes the circuit.
Block legs 1.2.3.4 for marching.
4. If the user inadvertently grips his thumb and leaves it on 9, the force will push the handle 7 down to C', which will also block the circuit (second
and Figure 4).

The watertightness of the axis X-Y of the stopper 12 supporting the handle 7 is ensured by a toroidal filling 15 with an adjusting screw 16.

Figure 3 shows an aperture L that allows fluid to fill the circuit.
7 is the indication. The entire structure is shown in FIG. 3 as a cross-sectional view taken along line 11iF--G in FIG.

Opposite the aperture 17 a ball 18 presses against a padding 19 in order to introduce or expel fluid by means of a syringe in order to adjust the initial height of the walker depending on the user's height, as the case may be. It is.

As you can see, this walker can be used to go up and down stairs (
(Fig. 5) or prove to be extremely effective for all regions. As long as the user grips the grip 9.10 to support himself, his hand automatically releases the handle 7.8.
