BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a lifting device for people with disabilities, a lifting device consisting of a mobile chassis and a upright on the chassis near its rear mounted upright column connected with lifting and support means for people with disabilities. rear, swivel support wheels.

By a lifting device of this kind known from German Publication No. 34 20 342, cf. THE

Patent No. 34 20 342, the chassis is constructed with considerable width and length, partly to ensure the necessary stability and partly to allow a wheelchair to be suitably carried around. Lifting devices with such a chassis cannot, in practice, pass through normal width openings.

If the chassis is narrow enough to pass through normal width openings, the desired lateral stability 20 will most often not be present.

Furthermore, from DE Publication No. 21 32 566, a lifting device is known for the disabled, whose cross-dimension is considerably smaller than the length dimension. However, 25 still remains the requirement for sufficiently wide cross-section to ensure the necessary lateral stability.

Further lifting devices are known if the side arms of the chassis can be swiveled. However, such designs are expensive and require careful operation.

In connection with known lifting devices of this kind, it is also known to place two 11 mm fixed axes with fixed axes between the front and rear support wheels in a preselected position relative to the center of gravity formed by the lifting device and one of the same. upright position lifted 2

disabled. However, this measure does not immediately contribute to the solution of that problem.

Furthermore, in connection with a lifting device for 5 disabled persons, known from the aforementioned DE Publication No. 34 30 342, it is known to provide it with foot plates to the feet of the disabled person, one on each side of the column.

It is an object of the invention to provide a lifting device for persons with disabilities of the above-mentioned type, which together with a simple construction with non-adjustable side arms is suitable both for access to wheelchairs and for passage through openings of normal width without the lateral stability is affected.

This object is achieved by a lifting device of the above type, which lifting device according to the invention is peculiar in that the chassis over at least one front end part 20 thereof has a width which is considerably smaller than the length of the chassis and that the track swivel support wheels are substantially greater than the track width of the front axles with fixed axis.

25

With a lifting device according to the invention, the front end is so narrow that it can easily enter between the front wheels of normal-width wheelchairs or between the front legs of normal-width chairs, the track width of the rear pivoting wheels on both sides of the upright column. provides significant lateral stability. Since the pivot wheels are arranged in one wide track, such a chassis can be easily operated through normal width passages.

The invention will now be described in more detail with reference 35

3 to the accompanying perspective drawing showing by way of example a preferred construction of a lifting device for persons with disabilities according to the invention.

5 The lifting device shown consists of a mobile chassis 1, which comprises a flat plate 2 of metal plate, and a removable upright column 3, from which associated lifting and carrying means 4 extend beyond the chassis 1.

A U-shaped cut-out 5 forms an opening in the front of the chassis 1, which enables it to be run around a toilet closet or an elevation for toilet purposes. The platform 2 has a constant width W which is considerably smaller than its length L, the length L being, for example, about 15 times the width W, and it has two fixed axes 6 supporting wheels located close to the front corners of the platform 2. At the rear corners, the platform 2 has laterally projecting and upwardly projecting boom arms 7, under which are mounted support wheels 8 which are of the two-wheel type, so that these rear wheels 8 have a track width which is substantially greater than the track width of the front wheels 6. This arrangement provides sufficient stability during lifting and transport of a disabled person, with a narrow chassis that can go in between the front wheels of a wheelchair or the front legs of an armchair 25 or reclining chair. For example, the width W may be about 43 cm.

The front wheels 6 are arranged in continuous elongated holes in the platform 2 with their common axis of rotation located within the thickness of the platform so that they protrude above and below it. Thus, the total height of the front part of the chassis 1 is equal to the diameter of the wheels 6, typically approx. 5 cm, so that the chassis can go under normal everyday furniture, such as sofas, sofa beds and similar items, which do not have sufficient clearance above the floor to allow a conventional lifting device chassis to enter. The rear support wheels 8 may have

DK 162503 B

4 any desired larger diameter.

Two intermediate wheels 9 with fixed axes similar to the wheels 6 are mounted on the platform in the same way as the wheels 6. The axis of the axes of the two wheels is such that the floor contact points of the intermediate wheels 9 are lower than the plane containing the wheels contact points 6 and 8 . Thus, the wheels 9 always contact the floor and the chassis 1 is able to tilt around these wheels, so that either the front wheels 6 or 10 the rear furniture wheels 8 contact the floor.

The column 3 is of square tube steel tubing and is removably supported in a base 10 welded to the center of the platform 2 near its rear end. The pedestal gives the pillar 3 a slight back slope of approx. 5 degrees. The lifting and support means 4 consist of a lifting arm arrangement which pivots about 11 on the column, and consists of an inner arm section 12 projecting from the pivot axis 11 and an U-shaped outer section which exhibits two laterally spaced lifting arms 13 between. As shown, a lifting loop S can be removably attached to attachment points 13a at the ends of the arms 13. The lifting mechanism consists of a lifting screw (not visible) inside the column 3, which can be manually rotated by means of a top crank 14 to raise and lower the arms 13 25 by means of a pivotable support 15 supporting the inner arm section 12 and attached to a carrier 16 which protrudes through a longitudinal slot 17 at the front of the column 3, which carrier includes a nut in engagement with the lifting screw.

30

Thus, the attachment points 13a swing in an arc around the pivot axis 11 to raise a disabled person carried by the sling S, which during use is guided around the disabled person's back under the arms. This allows the disabled person to be lifted from a sitting position with his face toward the column 3 to an erected, mostly standing position with the handy.

5, the feet of the footplates 18 of the platform 2 were capped and the knees of the disabled person in contact with the knee supports 19 protruding from the column 3 at knee height. In use, the lifting device is first moved to the disabled person with the front end of the chassis 1 freely moving under the wheelchair, armchair or the like on which the disabled person sits. The feet are placed on the footplates 18, whereby the knee supports 19 support the knees with the lower legs substantially vertical. With the sling positioned as described, the arms 13 can be raised by turning the crank 14 10 to raise the disabled person to a substantially upright position. Thus supported, the disabled person can be transported as desired, for example to a toilet, and returned to the wheelchair and put into it in the original sitting position.

15

With the disabled supported in the mainly standing position, the common center of gravity of the disabled and the lifting device is slightly behind the pivot axis of the intermediate wheels 9, so that the chassis 1 is supported on these wheels and also on the rear 20 supporting wheels 8. This gives a short wheelbase with a high degree of maneuverability. during transport, while the support wheels 6, which are now normally free of the floor, act as stabilizers which prevent the lifting device from tipping forward.

They also act as stabilizers and contact the floor, while the disabled person is raised from the sitting position and during most of the lifting movement when the center of gravity is located in front of the axis of the wheels 9.

Handles 20 which extend laterally from the arms 13 can be gripped by the disabled person to provide a sense of security and so that the disabled person, if strong enough, can assist in the lifting and support in the raised position. There are side handles 21 attached to the column 3 for use by the operator in moving the lifting device.
