Abstract

FIELD: medicine.

SUBSTANCE: invention relates to medical to appliances and can be used as an appliance that helps limited-mobility patients walk. Proposed apparatus comprises frame on rollers, leg with levers for arms and patient body support representing a multilink structure pivoted to aforesaid frame to be located between patient legs to repeat patient motion in walk. At least, one of multilink structure pivots is arranged to approach or remove from opposite pivot and is spring loaded to balance patient weight and to return to initial position at no-load state before starting walking.

EFFECT: instantaneous support of patient body in loss of stability.

Description

The invention relates to invalid equipment, in particular to devices for walking people with diseases of the musculoskeletal system.

A known apparatus for movement, which contains a pair of elements in the form of an inverted letter U and a cross member. The seat is pivotally attached to the frame and moves between the upper position when it is located vertically and the lower position when the seat is horizontal / 1 /.

Such an apparatus is suitable for a user who, at the time of fatigue, can independently change the position of the seat without assistance. A user who feels insecure and requires instant support is not protected from falling with such a design of the apparatus for movement.

Closest to the proposed apparatus is a movement apparatus containing a frame on rollers, levers for hands and a device for supporting the user's torso in the form of a web covering the chest, as well as a spring mechanism for balancing the mass of the user / 2 /.

This design of the apparatus limits the ability to restore the muscles of the legs and in some positions of the trunk makes it difficult for the user to breathe.

The present invention was the creation of a vehicle for movement, which at the time of unexpected fluctuations in the user's torso will provide him with instant support, a little rest in a sitting position and return to a vertical position without much effort to continue moving.

The problem is solved as follows.

A movement apparatus is proposed, comprising a frame on rollers, a rack with hand levers and a device for supporting the user's torso, in which, according to the invention, the device for supporting the user's torso is pivotally mounted on the rack for placing it between the legs of the user and made in the form of an articulated multi-link at least one of the hinges of which is installed with the possibility of its removal or rapprochement relative to the opposite hinge under the action of the load and spring-loaded to return it to a similar position when the load is removed before the start of the movement.

The proposed apparatus is shown in the drawings, where

figure 1 - General view of the apparatus;

figure 2 is a view of the details of the multi-link:

a) plan view of the face,

b) hinge axis;

figure 3 is a side view of the apparatus in a standing position of the user;

figure 4 is the same in an intermediate position;

figure 5 is the same in a sitting position;

figure 6 is a rear view of the apparatus in the user's sitting position;

Fig.7 is a view along A:

a) a view of a multi-link closed in a vertical plane,

b) the same in an intermediate position,

c) the same, closed in the horizontal plane.

The apparatus for moving a user comprises an open frame 1 on the rear of the rollers 2, the front 3 of which has an additional axis of rotation. Attached to the cross members 4 of the frame 1 is a stand 5 with levers 6 for the hands.

The device is equipped with a device 7 to maintain the body of the user. The device 7 is made in the form of a multi-linker and is, in particular, a prism, four faces 8 of which are pivotally connected by axes 9, 10, 11, 12 installed in the sleeves 15, mounted on the inner surfaces of the faces 8. The device 7 is mounted on a rack 5 by means of hinges 13, 14 to place it between the legs of the user in order to compensate for the fluctuation of the body when walking. The upper axis 12 of the hinge is connected with the spring 16 through the sleeve 17 of the hinge 13, mounted with the possibility of longitudinal movement relative to the rack 5. The bracket 18, attached to the rack 5, serves as an additional support for the lower axis 10 of the hinge.

As a result of these connections between structural elements, the opposite hinges 9-11, 10-12 are installed with the possibility of removal or rapprochement under the action of the load and the spring 16 returns to its original position when the load is removed before the start of movement.

A person in need of additional support while walking uses the proposed apparatus as follows. Holding hands on the levers 6, the user becomes in the area bounded on three sides by the frame 1 so that the device 7 for supporting the body was located between the legs of the user. The fixture 7 in the form of a prism closed in the vertical plane (Fig. 7a), turning relative to the strut 5, copies the user's movement, taking into account his vibrations, without interfering with his movement. In case of loss of stability, the user acts on the upper axis 12 with his weight. Under the influence of the load, the opposite hinges 10-12 come together, and the hinges 9-11 are removed relative to each other, and through the intermediate position (Fig.7c) it takes the position (Fig.7c) in the horizontal plane.

In this position, the prism forms a support for the user to rest while sitting.

Spring 16 prevents spontaneous folding of the prism in a horizontal plane and exerts resistance when lowering the user's body with increasing force. In the user's sitting position, the spring 16 balances its weight. To return the user to the position of movement, a light touch of the floor with his feet is enough. The spring 16 then returns the prism to a position folded in a vertical plane.

Claims (1)

An apparatus for moving, comprising a frame on rollers, a rack with levers for hands and a device for supporting the body of the user, mounted on a rack for placement between the legs of the user, characterized in that the device for supporting the body of the user is hinged with the possibility of copying the movements of the user when movement and made in the form of an articulated multi-link, and at least one of the hinges of the articulated multi-link is installed with the possibility of its removal or rapprochement relative to the opposite hinge under the action of the load and spring-loaded to balance the user's body weight and to return to its original position when removing the load before starting movement.
