PL234862B1 - Extend of an arm in the wall-mounted lift for disabled persons - Google Patents

Description

Description of the invention

The invention relates to a modification of a lift for the disabled, which is used to overcome architectural barriers.

STATE OF THE ART

Wall-mounted bathroom lifts for the so-called short-distance transport of disabled people are typical devices that facilitate the functioning of patients and their caregivers.

The simplest solutions for bathroom lifts are shown in Fig. 1. They are mounted on a plate permanently attached to the wall. The lifting structure (1) is pivoted on this plate. The column (2) is the basic structural element to which the lifting cylinder (3) and the carrying beam (4) are articulated. The transported person in a special sling (5) is suspended by a hook in the fixing point (PZ).

The person suspended in this way can be rotated in relation to the axis (1) only along a constant radius determined by the length of the supporting beam (4) and can be raised and lowered by controlled mechanical movements of the lifting cylinder (3).

More advanced solutions of the bathroom lift are shown in Fig. 2. The mounting of the lift and its rotation are analogous to the device described in Fig. 1. The differences between them are shown in Fig. 2. the bearing beam (4) has changed significantly. It has been extended and consists of two interacting parts of the main beam (4a) and a movably mounted extendable beam (4b). The PZ point has been moved to the end of the extendable beam (4b) so you can adjust its distance from the axis of rotation (1).

TECHNICAL PROBLEM

The disadvantage of this solution is that the adjustment of the position of the main beam (4a) and the extendable beam (4b) can be performed only without the transferred person (5) (relieving the PZ point).

SOLUTION TO SUBMIT

The subject of the invention is a bathroom lift with an additional mechanical possibility of extending the loaded transport arm.

The construction of the entire device shown in Fig. 3 does not differ in its principle of operation from the applied solutions. It is still the column (2) rotated around the axis (1). The main beam (4a) and the extendable beam (4b) are articulated to the column (2). This assembly, marked as a carrying beam (4), is raised and lowered with the lifting cylinder (3).

This results in moving and lifting the person in the sling (5).

The main difference is the change in the structure of the two-part supporting beam (4), shown in Fig. 3.

The applied change allows to move the person in the sling (5) suspended at the PZ point in the C directions without unloading the lift.

The solution described in Fig. 4 is characterized by the fact that the beam (4) consists of two cooperating elements (4a) and (4b) mechanically moved by an additional feed cylinder (4c).

In the solutions used so far, the main (4a) and extendable (4b) mating beams used were manually positioned and stabilized.

The difference is that thanks to the appropriate slide bearing ensuring smoothness and safety of movement, the extendable beam (4b) can be smoothly and steplessly adjusted in the main beam (4a) by means of a mechanical feed actuator (4c), which additionally becomes a self-locking lock after the end of movement. safety.

An additional thrust cylinder (4c) is attached to the main beam (4a) at point A and to the extension beam (4b) at point B. The cylinder attachment points A and B must be in the beam end sections (4a) and (4b). Thanks to this solution, the PZ suspension point of the person in the sling (5) can be moved smoothly in the direction of travel C shown in Fig. 4 despite the load and then block the position.

It is very important that the applied change allows to move the person in the sling (5) suspended at the PZ point in the C directions without unloading the lift. In practice, this solution enables the movement of a person in rooms with permanent architectural obstacles, such as screens covering pipes in bathrooms and / or in situations where the distances between the points used by the person are differently distant from the axis of rotation (1) of the lift.

Claims (2)

Patent claims 1. Extension of the arm in a wall lift for the disabled, including the column (2) rotated around the axis (1), characterized in that the main beam (4a) with an extendable beam (4b) is articulated to the column; 4), is raised and lowered by the lifting cylinder (3). 2. Extension of the arm in a wall lift for the disabled, according to claim 1, characterized in that the beam (4) consists of two mutually cooperating elements (4a) and (4b) mechanically moved by an additional feed cylinder (4c).
