Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lifting device. Lifting devices of this type have been known for a long time in a large number of different applications and embodiments and serve various purposes satisfactorily.

The object of the invention is a lifting device installed under the roof of the passenger compartment of a car, designed to raise and lower disabled persons into and out of the passenger car, with sufficient vertical displacement. It is an object of the present invention to provide a lifting device which is constructed as a simple, reliable and compact unit while reducing the stroke of the drive device so as to bring about the same.

To achieve the above object, the lifting device of the present invention includes a first support member that has an elongated shape and is attachable under the roof of the compartment, and a first support member that is installed under the roof of the compartment. a lifting device attached to the first support member so as to be suspended from the first support member when attached; the lifting device includes a lift device for movably attaching the lifting device to the first support member; a drive device attached to the second support member and operable to extend or retract along a line substantially parallel to the first support member; an elongated flexible lifting element adapted to be displaced in a direction, the lifting element being fixed at one end to an attachment point of said second support member and extending from said attachment point to said first support member. extending generally parallel to a first pulley and passing around the first pulley attached to and movable with the drive, the elevating element extending from the first pulley to the first support member; extending substantially parallel to a second pulley fixedly attached to the second support member adjacent to the attachment point, the elevating element passing over the second pulley and depending from the second pulley. and a lifting member for supporting a disabled person at the other end of the lifting element, so that when the drive device is actuated, the first pulley moves toward or away from the second pulley. The lifting element can be moved substantially parallel to the first support member to vary the longitudinal displacement of the lifting element and to raise and lower the lifting element respectively relative to the first support member.

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

The drawing is a schematic perspective view of a lifting device according to the invention.

The drawing shows one position of the support beam 1, which is the first support member carrying the trolley 2. A trolley 2 movable along a support beam carries a suspension member 2a, which
A second support member 15 is supported by a lifting device 3, which is schematically shown in the drawing. This lifting device 3 has a drive 4 built in the form of a motor. The motor is preferably electrical and can be driven via a cable 5 connected to a suitable power source. The motor is reversible and its driving direction can be controlled by a control handle 6. In the illustrated embodiment, a motor drives a ball screw mechanism 7, at the free end of which a yoke 8 carrying a first pulley member 9 is arranged. Drive unit 4, ball screw mechanism 7 and yoke 8
constitutes a drive device. A first pulley 9 movable together with the movable end of the ball screw mechanism and a second pulley 10 fixedly mounted at a distance therefrom are arranged. The two pulleys 9 and 10 are preferably arranged linearly in the extension of the ball screw mechanism. One end of the lifting element in the form of a belt 11 is fixed at an attachment point 12 located adjacent to the second pulley 10 . From there, the lifting element is arranged to pass over the first pulley 9 and back again to the second pulley 10, from which the free part of the lifting element hangs;
Its free end carries an elevating member, and in the illustrated example carries a mounting tool 13 having a seat plate 14.

When the drive motor is actuated in one direction via the control handle 6, the ball screw mechanism 7 transmits a rotational movement so that the yoke 8 is pulled in the direction relative to the drive motor. This causes the movable first pulley 9 to move away from the immovably mounted second pulley 10, which is located on the opposite side of the first pulley with respect to the motor, thereby causing the lifting element to One belt 11 is pulled upwardly, pulling up the elevating members 13,14. Since the free end 12 of the lifting element is mounted close to the immovably mounted second pulley 10, the lifting height is twice the displacement of the movable first pulley 9. Similarly, when the motor is reversed, the lifting members 13, 14 descend at twice the speed of the yoke 8 and the movable first pulley 9, and move twice as far.

By displacing the suspension member 2a of the lifting device laterally from the second pulley 10 for the lifting element 11, the free end of the lifting device can be moved closer to the coupe than the vehicle door when the suspension member 2a is in its lowest position. It can be moved into a model motor vehicle, with the seat board 14 positioned above the passenger chair or above the driver's chair.

Since the drive power for the lifting device or for the movement motor for trolley 2 can be taken from the vehicle's battery, this device is well suited for installation in a passenger car and can be easily operated by a single disabled person. can be controlled. Preferably, the suspension member 2a is telescopically telescopic in order to reduce its height and allow it to be stored.

The invention is not limited to the embodiments shown in the attached figures, but several modifications are possible within the scope of the claims. Therefore, various combinations and changes of details may be used in different embodiments;
It is also possible to use lifting devices designed in other ways than those shown.

Within the scope of the invention, it is possible to connect the lifting device immovably to the telescoping telescopic suspension member 2a.
