Description

The The present invention relates to a lifting device for a vehicle, in particular for use in a workshop, with two arranged approximately vertically Lifting columns, on each of which a plurality of support arms are arranged approximately parallel to the ground.

Out Vehicle technology lifting equipment for workshops are known. With these lifting devices can Vehicles raised for repair or inspection and lowered again so that the workshop personnel preferably the underbody area of the vehicle and make repairs to it.

The known lifting device has about two vertically arranged lifting columns corresponding e.g. hydraulic actuators on, wherein at the lifting columns two support arms are arranged approximately parallel to the ground. These Support arms can be pivoted so that for lifting a vehicle, the support arms below the vehicle can be moved, whereby the support arms brought into abutment with the underbody area can be. To lift the vehicle, the lever columns are now upwards accordingly drove, so that the vehicle resting on the support arms in a correspondingly higher position can be brought.

It However, it has been shown that especially in the new vehicles considerable areas the underbody area covered by cladding or the like are. As a result, can the support arms not readily in contact with the underbody area brought without destroying the panels. Therefore It is necessary that the panels are removed before lifting Vehicle dismantled and reassembled after repair. This means a considerable additional labor with the resulting resulting additional costs.

As a result, The present invention is based on the object, a lifting device for a vehicle to propose the genus mentioned above, which in the situation is to lift a vehicle without additional work on the subsoil can.

These The object is achieved by the Characteristics of claim 1 solved. Further advantageous embodiments will be apparent from the dependent claims.

According to the invention is a Lifting device for proposed a vehicle with preferably two approximately vertically arranged lifting columns, at each of which a plurality of support arms arranged approximately parallel to the ground are. According to the present Invention is provided that at the free ends of the support arms at least one adapter change element for receiving a vehicle tire is provided. Thus, you can any vehicles over the wheels or the vehicle tires picked up by the lifting device and be fixed to the right height, so that the vehicle without additional Dismantling of provided on the underbody panels panels or the like can be raised or lowered. Without the Adapter change elements it is possible the lifting device according to the invention also to use in the known manner.

in the Frame of an advantageous embodiment of the present invention can be provided that each adapter change element at least one Pick-up area for picking up a vehicle tire and a mounting area for securing the adapter change element to a support arm. Thus, the vehicle can over the vehicle tires raised by the lifting device according to the invention being, whereby by the changeable Admission areas of the adapter change vehicles with different Tire or rim sizes raised can be. In addition, you can the respective adapter change elements on the support arms on the respective attachment area detachable be attached so that the application of the lifting device according to the invention is advantageously extended, since it is possible, other suitable To provide change elements on the support arms of the proposed lifting device.

special Dern It is advantageous if the receiving area of the adapter change element essentially forms a U-shape. In this embodiment of the Adapter change elements can the support arms in an advantageous manner laterally to the vehicle tires guided so that the U-shaped receiving area accommodate each adapter change element the respective vehicle tires can. It is also conceivable that the receiving area other suitable can take constructive forms. In particular, the basis of the U-shape adjustable in length so that the adapter change element adapted to the respective vehicle tire size can be.

According to a further development of the present invention, a clip element or the like may be provided as a fastening region at the base of the U-shape. With this clip element, the respective Adapterwech selelement be releasably secured to the support arm by the clamp member almost embraces the respective support arm. Other releasable connections may also be used to remove the respective adapter change element from the support arms at any time.

Preferably can the legs of the approximately U-shaped Adapter change element such to the shape of a male vehicle tire be adapted to a lifting done in a secure manner can. For this it is particularly advantageous if the legs in cross section form an isosceles triangle, with the base side of the triangle facing the vehicle tire respectively.

at the lifting device according to the invention the support arms are pivotable and telescopic, so that each support arm is adjustable so that the adapter change elements each attachable to a vehicle tire, so that the vehicle in the simplest way without additional Workload can be raised or lowered again.

following the invention proposed here will be explained in more detail with reference to the accompanying drawings. It demonstrate:

1 a three-dimensional view of an adapter change element on a support arm of a lifting device according to the invention;

2 a basic position of the lifting device according to the invention; and

3 a raised position of a vehicle with the lifting device according to the invention.

In 1 shows a possible embodiment of a lifting device according to the invention for a vehicle in a workshop or the like. The lifting device has two approximately vertically arranged lifting columns 1 . 1' on, on each of which two support arms 2 . 2 ' are fastened approximately parallel to the ground. The support arms 2 . 2 ' are pivotable on the lifting columns 1 . 1' fastened, with the free ends of the support arms 2 . 2 ' are telescopic.

According to the invention, at the free ends of each support arm 2 . 2 ' one adapter change element each 3 . 3 ' for picking up a vehicle tire 4 intended.

In 1 is the adapter change element 3 shown in detail. The adapter change element 3 has a receiving area for receiving a vehicle tire 4 . 4 ' and a fixing portion for fixing the adapter exchange member 3 on a support arm 2 on, with the telescopic arm 2 at the lifting column 1 is articulated.

The receiving area is formed as a U-shape, wherein the base 5 the U-shape a clip element 6 has as a mounting area. The clamp element 6 is detachable at the free end of the support arm 2 attached. The two thighs 7 . 7 ' the U-shape of the adapter change element 3 are the shape of the respective vehicle tire 4 adapted to the vehicle to be lifted. According to the invention, the legs 7 . 7 ' the U-shape formed as an isosceles triangle, the bases 8th . 8th' every thigh 7 . 7 ' on the vehicle tire 4 lie when the vehicle is to be raised.

In 2 the lifting device according to the invention is shown in a basic position, wherein the support arms 2 . 2 ' are placed on the ground so that a vehicle between the two lifting columns 1 . 1' the lifting device can be driven. Subsequently, the support arms 2 . 2 ' the lifting device with the respective adapter change elements 3 . 3 ' laterally to the vehicle tires 4 . 4 ' be driven so that the thighs 7 . 7 ' the U-shaped receiving portion of each adapter change element 3 . 3 ' on the respective vehicle tire 4 . 4 ' issue. Finally, the lifting columns can 1 . 1' be lifted by a hydraulic actuator, so that the support arms 2 . 2 ' move the vehicle upwards. Such a position of the vehicle is in 3 shown.
