Description

[0001] The invention relates to an adapter for a lifting platform, in particular for lifting motor vehicles.

[0002] Vehicle lifts are widely used for the inspection, maintenance, and repair of motor vehicles. These lifts are used to raise a vehicle to relieve pressure on the wheels, for example, so that a tire can be changed. Raising the vehicle also provides better access to the vehicle's underbody for inspection, maintenance, or repair. For this purpose, the vehicle must be securely positioned on the lift to avoid endangering a worker underneath and to prevent damage to the vehicle.

[0003] Modern lifts typically found in workshops have arms that can be positioned to the right and left of the vehicle. These arms can be pivoted under the sill on the driver's side and passenger side of the vehicle. At the end of each arm, a support plate is placed under designated support points before the arms of the lift are raised to lift the vehicle. The support plates come into contact with the designated area of ​​the underbody or sill and thus support the vehicle when the arms are raised further. For typical vehicles with an internal combustion engine, this is typically sufficient, especially since the support plates are typically round and have a sufficient diameter to provide a secure support surface. The tops of the support plates are also covered with a non-slip rubber or plastic material, etc.Such lifting platforms have become known, for example, from the publications DE 10 2018 105 573 A1, US 4 212 449 A, DE 21 30 653 A and DE 71 28 036 U. DE 20 2013 102 803 U1 discloses a lifting platform with support arms, wherein holes are provided at the ends of the support arms for the interchangeable arrangement of support elements.

[0004] In modern electric vehicles, however, the drive battery, also called traction battery, of the electric vehicle is designed as an underbody battery and is attached to the vehicle from below and at least partially forms the underbody and / or is attached to the underbody.

[0005] This makes the underbody battery accessible during servicing, which requires raising the vehicle using a hoist. The support plates must be positioned under the vehicle as described above. However, it may happen that the support plates are positioned too far inward, which could block the underbody battery. To prevent this, a worker might be tempted to position the support plate too far outward, resulting in the support plate's load-bearing area being too small, which could pose a danger to both the worker and the vehicle.

[0006] It is the object of the present invention to provide an adapter for a lifting platform which is designed simply and inexpensively and allows a defined support of the motor vehicle, so that the above-described danger for workers and motor vehicle due to improper placement of the support plates is avoided.

[0007] The problem is solved with the features of claim 1.

[0008] One embodiment of the invention relates to an adapter for a lifting platform, wherein the adapter has a base body which has a plate, a protruding edge, and a protruding pin, wherein the protruding edge is fastened to the edge region of the plate and protrudes from the plate in a first normal direction, and the protruding pin is fastened to the plate off-center and protrudes from the plate in a second normal direction, wherein the first normal direction is oriented opposite to the second normal direction. Thus, the adapter can be securely and easily placed on the receiving plate of the arm of the lifting platform in order to hold the vehicle with the pin, which engages in a provided opening on the underbody or sill of the motor vehicle.

[0009] The edge does not have to be circumferential, but it can be. If the edge is not circumferential, the edge can be formed by a number of teeth, etc.

[0010] It is particularly advantageous if the protruding edge is connected to the plate or is made as a single piece with the plate. This results in a simple, stable, and therefore safe design.

[0011] It's also advantageous if the protruding edge is screwed, riveted, or welded to the panel. This also results in a simple, stable, and therefore secure design.

[0012] It is also advantageous if the protruding edge is manufactured as a single piece with the plate, either as a cast part or as a machined component, for example, by milling. This also achieves a simple, stable, and therefore safe design.

[0013] It is also advantageous if the protruding pin is connected to the plate or is made as a single piece with the plate. This results in a simple, stable, and therefore secure design.

[0014] Furthermore, it is advisable for the protruding pin to be screwed, riveted, or welded to the plate. This also achieves a simple, stable, and therefore secure design.

[0015] In a further embodiment, it is also advantageous if the protruding pin is manufactured as a single piece with the plate as a cast or machined component. This also achieves a simple, stable, and thus secure design.

[0016] Furthermore, it is also advisable for the plate to have at least one hole for screwing and / or riveting the edge and / or the tenon. This also ensures a simple, stable, and therefore secure design.

[0017] It is also preferred if the plate, edge, and / or tenon are made of metal, particularly steel or aluminum. This ensures a stable design that is permanently ready for use in the workshop.

[0018] It is particularly advantageous if the pin is cylindrical and has a continuous diameter or if the pin is cylindrical and stepped and has at least two different diameters.

[0019] The invention is explained in detail below using an exemplary embodiment with reference to the drawing.

[0020] The Fig. Figure 1 shows a prior art lifting platform 1 with an arm 2 carrying a support plate 3 for lifting a motor vehicle 4. To do so, the support plate 3 is pivoted under the sill 5 or underbody of the motor vehicle 4, and the arm 2 is raised. A typical lifting platform has four such arms 2 with support plates 3, two of which are placed spaced apart on opposite sides of the motor vehicle 4. The support plate 3 has a support 6 made of a non-slip rubber or plastic.

[0021] The Fig. 2 and Fig. 3 show different views of an adapter 10 according to the invention for a lifting platform 1. The Fig. 8 and Fig. 9 show sections of details of the adapter 10.

[0022] The adapter 10 according to the invention has a base body 11 which has a plate 12, a projecting edge 13 and a projecting pin 14.

[0023] The edge 13 protruding from the plate 12 is attached to the edge region 15 of the plate 12. The edge 13 protrudes from the plate 12 in a first normal direction 16.

[0024] Furthermore, the protruding pin 14 is fastened to the plate 12 off-center. The pin 14 protrudes from the plate 12 in a second normal direction 17. The first normal direction 16 is oriented opposite to the second normal direction 17. The edge 12 and the pin 14 protrude from the plate 12 in opposite directions.

[0025] The protruding edge 13 is formed integrally with the plate 12 or is manufactured in one piece with the plate 12. The exemplary embodiment shows that the edge 13 is formed integrally with the plate 12. For example, the protruding edge 13 is manufactured in one piece with the plate 12 as a cast part or as a machined component, for example, as a milled component.

[0026] Alternatively, and not shown, the edge 13 can also be connected to the plate 12. Thus, the edge 13 can be screwed, riveted, or welded to the plate 12.

[0027] The protruding pin 14 can also be connected to the plate 12 or made in one piece with the plate 12. In the illustrated embodiment, the protruding pin 14 is screwed to the plate 12, but it can also be riveted or welded. For screwing, the plate 12 has a bore 18, with the pin 14 having a blind hole 19 with a thread so that a screw 20 can be screwed in, see Fig. 3.

[0028] Alternatively, the protruding pin 14 can also be manufactured in one piece with the plate 12 as a cast part or as a machined component.

[0029] As already described above, the plate 12 can have at least one bore 18, in particular for screwing and / or riveting the edge 13 and / or the pin 14.

[0030] In order to achieve the intended durability, the plate 12, the edge 13 and / or the pin 14 is / are made of metal, in particular of steel or aluminum.

[0033] In Fig. Figure 4 shows how the adapter 10 is manually placed onto the support plate 3 of the lifting platform 1. The plate 12 rests on the support plate 3, and the edge 13 surrounds the support plate 3, ensuring a secure positioning of the adapter 10 on the support plate 3 and preventing the adapter 10 from slipping off the support plate 3.

[0034] In Fig. 5 shows how the adapter 10 sits on the mounting plate 3.

[0035] In Fig. 6 shows how the arm 2 is pivoted so that the adapter 10 can be placed under the sill 5 of the motor vehicle 4.

[0036] In Fig.Figure 7 shows how a motor vehicle 4 can be lifted using the adapter 10 on the support plate 3. For this purpose, the pin 14 engages in a designated opening 21 or receptacle on the sill 5 or underbody of the motor vehicle 4, thus ensuring secure support. This allows the motor vehicle 4 to be lifted safely.

[0037] The diameter D2 is adapted to the diameter of the opening 21 or receptacle and the diameter D1 is larger than D2, so that the motor vehicle 4 rests securely on the step 22 from D1 to D2.

[0038] Since the pin 14 is arranged off-center of the plate 12, as shown in the figures, the plate 12 does not extend so far under the underbody, so that any underfloor battery or similar can still be removed safely.

[0039] The adapter 10 can be easily and quickly attached to the support plate 3 and can also be easily and quickly removed again, so that the lifting platform 1 can be used with or without the adapter.
