The portable lift for bedridden patients and the disabled is modular with the ability to attach it to a wall, a car, floor - ceiling. So, the lift has a cart with wheels, which has a vertical stand (1), which is located on a U-shaped base (2), equipped with four swivel wheels (3). The vertical post is fixed on the horizontal part of the U-shaped base. In this case, the width of the U-shaped base is adjustable and depends on the width of the passage where this lift is used. The upright post has a square section. In the upper part of the vertical post, on the inside, two pins are welded one above the other for hanging the removable part of the lift. A through hole is made between the pins in the rack, into which a clamping device is screwed in from the outside of the rack, in the form of a fixing unit on the thread, which prevents rotation of the suspended part of the lift, its overturning and provides more reliable stability in space. The fixing unit (9) is equipped with a handle (not shown in the drawing) to improve ease of use. On the sides of the rack there are handles (6), the ends of which are covered with rubber grips, to increase the ease of use and prevent hands from slipping during use. The hinged part of the lift consists of a rectangular hollow body (4), in which the battery is located, which makes it possible not to depend on an external source through stamps or connectors.

The vertical post is fixed on the horizontal part of the U-shaped base. In this case, the width of the U-shaped was adjusted depending on the width of the apartment corridor. In the upper part of the vertical post, on the inside, two pins are welded one above the other for hanging the removable part of the lift. A through hole is made between the pins in the rack, into which the outer side of the rack was screwed with a clamping device in the form of a locking unit on the thread, and the lift body was fixed on carts with wheels, there is no play, the rotation of the hinged part of the lift is prevented, which prevents it from overturning and provides more reliable stability in space. In this case, the hinged part of the lift consists of a rectangular hollow body in which the battery is located, which makes it possible not to depend on an external source through stamps or connectors. And the battery is charged through the connector located at the bottom of the case. In addition, the absence of an external power supply reduces the dimensions of the device and increases its operational capabilities, in particular, ease of use. The battery is covered with a plate, which is fixed with screws on the case, which ensures maintainability. From the bottom of the battery, there is a wire to the remote control, an electric drive wire and a charging socket. On the back of the case, two loops are welded on, corresponding to two pins on the vertical posts, allowing you to hang this module on the posts and fix it with a clamping device to prevent turning and overturning, in addition, quick-release is realized. On the upper part of the case, by means of screws, two rectangular crossbars are fixed, the free ends of which are connected by a plate. An electric drive is located in the lower part of the body, due to which the movement of bedridden patients is carried out. By means of the remote control, we electrically actuate the drive and carry out the lifting and transfer of the patient.

In addition, the lift can be wall-hung and used in a car.
