Ramp buffer with movable part

The innovation is a ramp buffer for absorbing the force sauce during
Starting motor vehicles with the features of claim 1.

To load and unload goods, vehicles drive backwards against the ramp, which usually contains loading bridges for placing on the vehicle loading area.
To prevent damage to the ramp and vehicle, the following steps are

Ramp buffers are attached to the ramp edge to cushion the impact when docking.

If the vehicles are not higher than the ramp, this well-known solution works well.

However, problems are caused by vehicles that are higher than the ramp, especially the so-called swap bodies, which are parked in front of the ramp and where the towing vehicle is removed during the loading process. Very often with these
It is also desirable to be able to open and close the rear doors of vehicles when the swap body is at the ramp.

To meet these requirements, the ramp buffers must then be
protrude above the top edge of the ramp, as this is the only way they can catch the approaching vehicle. If the vehicle is now at the ramp, the rear doors can no longer be opened, as the ramp buffers protruding over the ramp are in the way.

Known solutions to the problem consist of making the ramp buffers height-adjustable so that they can be lowered after the vehicle has docked. Utility models DE 295 03 742 and DE 296 00 207 as well as patent application DE 195 121 and patent DE 195 25 308 show such solutions. All of the solutions mentioned have the disadvantage that a lot of force is required to lower the buffer when the vehicle is docked, if this is even possible. The stability of the structures is also questionable, since high stability influences the depth of the ramp buffers, which in turn leads to more expensive loading bridges and dock seals.

0 The aim of the innovation is to eliminate the disadvantages mentioned and to ensure a stability of the construction that can safely withstand the starting forces of the vehicle. The innovation solves this problem by providing a two-part ramp buffer on both the left and right of the loading opening, with an extra-wide buffer part firmly attached to the ramp on each side, which ends at the top edge of the ramp, and a second buffer part that can be moved sideways on the first buffer part mentioned. In addition, the second buffer part is wedge-shaped in plan and can therefore be pushed to the side relatively easily even when subjected to pressure from the vehicle.

Low vehicles only impact the lower buffer part on each side, the upper part can be moved to the side for loading and is no longer in the loading opening. High vehicles hit the upper buffer part on each side and are safely intercepted. Due to the wedge shape, these upper movable buffer parts can simply be moved to the side away from each other and also free up the entire loading opening. The rear doors of the high vehicles can now also be opened and closed without the vehicle having to drive away.

A displacement of approximately 350 mm outwards per buffer must generally be sufficient to clear the loading opening. The manner in which the ramp buffers are displaced sideways is within the scope of specialist knowledge and is not the subject of the invention. This can be done mechanically using lever arms, by spring operation, electrically, hydraulically, pneumatically, or in another way.

The innovation is explained in more detail using the drawings, where:

Figure 1 shows the left ramp buffer standing in front of the ramp,

Figure 2 shows a section along the line A-A through Figure 1, Figure 3 shows the plan of the left ramp buffer, especially the movable part and ·

Figure 4 shows the section through a special mounting profile. . -i

Figure 1 shows the left ramp buffer when you are in front of the ramp and looking towards the ramp. (1) represents the ramp, the right side of which runs vertically downwards to form the recess for the installation of a loading bridge. The ramp (1) could also run horizontally to the right ramp buffer. You can also see the upper buffer part (2), which can be moved in the direction of the arrow, and the lower buffer part (3) attached to the front edge of the ramp. The lower buffer part (3), the structure of which is explained in more detail below, is firmly connected to the ramp (1) by fastenings (8), but can also be welded to a steel profile (4) cast into the front of the ramp.

As can be seen from Figure 2, the lower buffer part (3) consists of a support profile (5) with a U-shaped edge on its upper and lower edges, extending over the entire sliding range of the upper buffer part (2), side plates (6) welded to it, a base plate (9) connected to the side plates, the rubber buffer (7) and the cheeks (20) connected to the support profile (5) for attaching a sliding angle (16). If the lower buffer part (3) is to be screwed to the ramp, the appropriate fastening means (8) are sunk into the rubber buffer (5).

The upper, laterally movable buffer part (2) also has a U-shaped bent steel profile (10) which grips the support profile (5) like a claw and is supported by a base plate (12) and stiffening plates (11) on a support profile (18) which is attached to the ramp (1) over the entire width of the lower buffer part, including the displacement area. This support profile (18) can be welded to a ramp profile (4) cast in concrete or screwed to the ramp (1). The rubber buffer (14) is attached to the steel profile (10) using screws (15). Sliding plates (13), which can be attached to the steel profile (10) and the base plate (12), for example, ensure that the upper buffer part (2) can be easily moved. If the upper, laterally movable buffer part (2) is placed on the lower buffer part (3), a sliding angle (16) is attached to the cheeks (20) with screws (17). "■■■;·,.

The new requirement that the rubber buffer (14) should have a surface that rises horizontally outwards at a small angle α cannot only be met by

This can be achieved by using a suitably shaped rubber buffer. As can be seen from Figure 3, filler pieces (19) can also ensure a suitably inclined shape of the upper, laterally displaceable buffer part (2). At the same time, this figure shows that the upper buffer part (2) can be easily displaced laterally outwards when a motor vehicle (22) has approached the ramp.

The buffer shown in Figures 1 to 3 is particularly suitable for ramps that protrude from the building facade or have a wide gate in order to ensure space for lateral displacement. Figure 4 shows a trough-shaped bent special profile (21) that is attached to the ramp and carries the buffer construction according to the innovation, thus enabling installation on ramps that are in the same plane as the building facade and have a narrow gate.

It is also within the scope of the invention to design not the upper buffer part (2), but its guide through the steel profile (10) or the support profile (5) or the special profile (21) in such a way that an inclination (α) is achieved with respect to the ramp (1) in order to be able to move the upper buffer part (2) acted upon by the vehicle (22).
