Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a deformable seal of a gap between a building opening and a vehicle approached therewith.

The described guide rod has the task of allowing an evasive movement of the frame when the apron is deformed by a vehicle driven in front of the building opening. If the length of the guide rod cannot be varied or no other measures are taken, the frame together with the apron will be slightly raised, while the laterally arranged upholstery will be significantly distorted. . Such distortions and deformations can lead to premature wear of the upholstery.

The invention aims to improve the seal mentioned at the beginning in such a way that special measures for the guide rod and for the movement mechanism of the suspension of the frame are not required, and in such a way that oblique stresses in the upholstery do not lead to the above-mentioned damage. is essentially the issue.

In order to solve this problem, according to the invention, the edge portions of the upholstery on both sides of the apron facing the building are arranged to be variable in height. This can be done by displaceably mounting the edges in longitudinal grooves which are advantageously undercut to achieve locking.

An edge supported in this way allows for a displacement that can be adjusted depending on the diagonal stress of the upholstery. In this case, it is clear that this edge is prevented from slipping out of the groove in an abnormal manner, for example by fixing it at its upper end. That is, if the above-mentioned edge is placed firmly and therefore non-displaceably on the building in its upper end region, a sufficient amount of displacement can still occur due to movement of the lower part of the upholstery. It is.

This height variation can take place against the action of a restoring force, for example against the action of a tension spring.
However, when the distortion of the upholstered fabric is not too large, in order to lower the edge, normally,
The weight of the upholstery is sufficient.

The present invention provides that the edge of the upholstery recovers quickly, but at the same time, when the seal is loaded by the vehicle, the deformation resistance of the front apron in contact with the seal is magnified and therefore The object is to improve the seal mentioned at the beginning in such a way that all contacting deformable and movable front parts have inertia.

In order to solve this problem, according to the present invention,
A tension spring is provided. This acts on the guide rod and/or the U-shaped frame in such a way that the edge of the upholstery can only be moved upwards against the action of the tension spring. Particularly in this case, in the diagonal direction of the parallelogram formed by the building exterior, the U-framework and the two guide bars parallel to each other, or essentially in the direction of said diagonal, if appropriate with a rope. A tension spring is used which acts in combination.

This tension spring causes that, before the frame is moved in the direction of the building by a displacement of the guide rods, a considerable deformation of the apron first occurs, and this causes a correspondingly strong force of the U-form. It acts in such a way that a mechanical load must first occur. If this load decreases and therefore the vehicle leaves the building, the guide rod returns or the U-frame moves forward.
In this case, the edges of the side coverings also descend. This spring therefore also acts directly on the return of the edge. At the same time, sufficient deformation of the apron takes place, so that a good seal to the vehicle can be achieved.

The figures showing examples will be explained in more detail.

A building 1, for example a warehouse, has an opening 2 to which vehicles with a rear deck can approach for loading and unloading in advance. On either side of this opening 2 there is a vertically extending upholstery 3 and a horizontally arranged upholstery 4 above it. These upholstery forms the connection from the building 1 to the apron, which has a vertical section 5 and a horizontal section 6 on either side of the opening 2.

These sealing parts 3, 4, 5 and 6 are made of waterproof, flexible foil, rubberized fabric or the like.

The opening 2 is surrounded by a U-shaped frame consisting of vertical arms 7 and crossbars 8. These parts formed as metal profiles are firmly fixed to the building 1 and are used for fixing the edges of the upholstery fabric 3 and the horizontal upholstery fabric 4. The edges of the upholstery 3 and 4 facing away from the building 1 are firmly fastened to another U-shaped frame consisting of vertical metal sections 9 and horizontal sections 10.

In the essentially square profiles 7, 9 there are longitudinal grooves 11 which are rounded and slightly undercut. This serves to accommodate the doubled edges of the upholstery 3. In order that the upholstery 3 cannot be pulled out of the longitudinal groove 11 when the tension is horizontal, a removable rod-shaped core 12 is provided for increasing the thickness. The aprons 5 and 6 fit into the small grooves 13 of the profile 9 on the inside, and the aprons 5 and 6
It is clamped or riveted there to prevent it from slipping out.

In the building 1 or the profile 7, on each side of the opening 2,
Two guide rods 14 are disposed that are attached via a connecting portion 15 and extend obliquely upward. These guide rods 14 support a downwardly open U-shaped frame with profiles 9, 10 and therefore all sealing parts connected to these profiles. In this case, the upholstery fabrics 3 and 4 are under tension;
This is caused only by the weight of the member connected to it.

In this case, the upholstery 3, 4 is weatherproof on the sides and above. In that case, the aprons 5, 6 form the actual seal. The apron deforms as if to form a seal when contacted by a vehicle not shown in the drawings.

If the apron is deformed, the U-shaped frames 9, 10
However, it is unavoidable that pressure is applied in the direction of the mismark 16. This results in a displacement of the guide rod 14 in the direction of the arrow 17, with the U-shaped frames 9, 10 being lifted upwards and the upholstery 3 being distorted accordingly.

According to FIG. 3, the edges of the upholstery 3 fixed to the profile 9 are tightly tightened. On the other hand, the edge portion on the building side is disposed in the groove 11 so as to be displaceable and height variable. This can also act against distortion in the above-mentioned direction, with the upholstery 3 being able to slide more or less upwards, ie in the direction of the arrow 18, in response to this distortion. However, in order to prevent the tension cloth 3 from descending, the tension cloth is
or is otherwise fixedly disposed.

Therefore, the edge placed on the side of the building is fixed only at the top, while the bottom part is displaceable and hangs downwards only under its own weight, and is also fully taut. .

However, if the upholstery 3 is relatively light, a tension spring can be provided at the lower edge of the upholstery, which will prevent the upholstery when no distortion or height fluctuations of the front frames 9, 10 occur anymore. The cloth 3 is always returned to its position according to the drawing. In some cases, upholstery 3
The lower part of the front edge of can also be made movable and variable in height. However, in normal cases it is sufficient to displaceably support the rear edge of the upholstery 3 or the right edge facing towards the building.

This displaceability of the edge certainly has the advantages mentioned above. However, this displacement possibility is, in this case,
Even a slight force acting on the apron can lead to the apron 5, 6 being deformed without undergoing an effective deformation for a good sealing effect for close contact with the vehicle.

A tension spring 21 is connected to the tension rope 20 in order to obtain the advantage of displaceability and also improve sealing properties.
is connected to the profile 9 at the connection point 22 of the upper guide rod 14, while the pulling rope 20 is connected to the connection point 15 at the lower end 23, where The lower end of the lower guide rod 14 is connected to the section 7 in a flexible manner.

The tension spring 21 and the tension rope 20 therefore run along the diagonal of the parallelogram defined by the two guide rods 14 and the two profiles 7 and 9. The tension spring 21 is loaded when the apron is loaded, and it resists the displacement of the guide rod in the direction of the arrow 17. As a result of this resistance of the tension spring 21, a movement of the apron in the direction of the arrow 16 takes place, which then first causes the apron to achieve a seal before a movement of the edge of the upholstery 3 towards the building 1 takes place. It undergoes sufficient transformation. The tension spring 21 then takes on the task of returning the apron to its rest position, which likewise applies to the aforementioned edges. As far as this goes, the tension spring 21
fulfills a dual function.
