Arrangement for attaching tensioning and/or pulling devices

DE-PS 38 03 248 discloses an arrangement for attaching tensioning and/or pulling means, which comprises a U-shaped bearing block that can be fixed in place by welding and a self-contained swivel bracket that is captively coupled to the bearing block by a retaining web that can be fixed in position between the legs of the bearing block.

Such an arrangement is provided, for example, in a truck in order to be able to connect it securely to the respective means of transport (railway car, ship) during transport on the rail or on the water. In addition, such an arrangement can be assigned to containers that have to be transported hanging and, if necessary, tilted. Machines can also be transported in a position-secured manner using this arrangement. The tensioning and/or traction devices can be chains of various designs, ropes or straps.

The front sides of the legs of the well-known bearing block are each bevelled at an angle of 45°. Together with the opposite fastening surface for the bearing block, they define a space with a triangular cross-section for the insertion of weld seams.

A retaining bar punched from a plate is clamped between the free ends of the legs. The retaining bar has the task of holding the bearing block and the swivel bracket together after they have been manufactured separately for the purpose of storage and transport. The bearing block and swivel bracket thus form a storage and transport or assembly unit. On the other hand, the formation of spacer ribs on the retaining bar ensures that the inclined front surfaces of the legs can always be positioned at the optimal distance from the fastening surface for proper weld seams.

The swivel bracket is designed in the form of a so-called D-bracket with a circular cross-section. The swivel bracket has a straight web with which it can be fixed in position in the bearing block with the help of the retaining web. The web is followed by two parallel legs, which in turn are connected to one another via an arched web.

Regardless of where the known arrangement is used, it has the property that the swivel bracket can swing back and forth by about 180° without limitation if the swivel bracket is not subjected to any kind of tensile stress. This means, for example, in the case of a truck driving on the road, that, depending on the condition of the road surface, the swivel brackets, which in this case are arranged in a hanging position, are permanently pushed against parts of the truck.

The noise level generated by this impact can be not only unpleasant, but also harmful to the human ear.

Because when using the known arrangement on a truck, the swivel brackets usually hang freely next to the vertical web of a double-T beam, it is necessary to lift the swivel bracket off the web with one hand during the tensioning process so that, for example, a hook arranged at the end of a round link chain, a rope or a band can be hooked into the swivel bracket. This process is often difficult because the other hand is needed for other tasks. It cannot be ruled out that if the hook is hooked in incorrectly, fingers could be crushed.

But even if the known arrangement is welded onto a flat surface, especially on the edge of this surface, there are disadvantages. This is particularly the case because the swivel bracket can protrude over the edge into the free space and thus form an obstacle. Other objects can hit this obstacle and be damaged. It is also quite conceivable that the arrangement could be damaged to the point where it is no longer functional and must be replaced with a new, usable arrangement, which requires relatively complex measures.

The invention is based on the prior art and is based on the object of creating an arrangement for attaching tensioning and/or pulling means, which allows the swivel bracket in the non-tensioned state to be given a position which enables the generation of at least

unpleasant noise levels and ensures easier handling of the arrangement.

According to the invention, this object is achieved by the features of claim 1.

The most important aspect here is the extension of at least one leg of the bearing block beyond its front sides. These extensions thus form swivel limits for the legs of the swivel bracket. If the arrangement is assigned to a double-T-shaped longitudinal beam of a truck, for example, the position of the bearing block relative to the longitudinal beam is such that the extensions prevent the hanging swivel bracket from hitting the web of the longitudinal beam and causing unpleasant noises. Furthermore, this standby position of the swivel bracket has the property that it is at a distance from the web. Due to this distance, a second hand is no longer required, in particular to hook a hook-shaped end link into the swivel bracket when the truck has to be lashed down on a ship or a railway carriage. The bracing and lashing work is made significantly easier.

If, however, the bearing block is attached to a surface, and in particular to the edge of this surface, the arrangement is made in such a way that a longer leg is located next to the edge of the surface. The swivel bracket can therefore no longer swivel beyond the vertical plane that intersects the edge and protrude freely, so that it forms an obstacle there. Instead, it is now possible to raise the swivel bracket vertically for a bracing or shifting process so that it rests against the extensions. Now, too, without

With the help of the other hand, a hook can easily be hooked into the swivel bracket.

The invention also allows both legs of the bearing block to be extended beyond its front sides. This creates a double swivel limit for the swivel bracket. Thanks to the stop defined on both sides, the bearing block can now also be positioned in the middle of a U- or double-T beam. This allows a greater range of variation in terms of the respective spatial lashing options.

An advantageous embodiment of the basic idea of the invention is seen in the features of claim 2. This design makes it possible, for example, when assigning the arrangement to a double-T beam of a truck, to fit the bearing block in a targeted manner in the corner area below an upper horizontal flange between this and the vertical web. The bearing block with the swivel bracket oriented in this via the retaining web only needs to be moved upwards along the web with the flat outer surface of the long leg resting on the web until the flat front surface of the short leg also comes to rest on the underside of the flange. The bearing block has then reached the final position and can now be finally fixed first by fixing it at certain points and then by applying the weld seams. The relative position of the flat outer surface of the long leg to the flat front surface of the short leg ensures that in the hanging arrangement the swivel bracket is located on the extensions of a long leg and is thus in an inclined position at a distance from the web. The attachment of a round link chain, a rope or a

It is then possible to easily attach the hook arranged on the textile bands to the swivel bracket.

The extensions on at least one leg of the bearing block also have the advantage that double-T-shaped longitudinal beams with comparatively thin webs can be used, especially in conjunction with a truck. A long leg eliminates the reduction in the thickness of the webs and ensures a sufficient welded connection between a flange of the longitudinal beam and its web. The introduction of force into the longitudinal beam is thereby optimized.

But even when welding the bearing block onto a flat surface, especially on the edge of this surface, the extensions on at least one leg offer particular advantages. The long leg is then positioned next to the edge of this surface. The swivel bracket can therefore only be swiveled back and forth between the extensions or the surface. However, it can no longer swivel beyond the plane running through the edge of the flat surface and create an obstacle.

In order to be able to fix the swivel bracket in the swivel area between the extensions and a welding surface for the bearing block in the standby state independently of the extensions, it is provided according to the features of claim 3 that a recess for receiving an elastic pressure medium is made in the bearing block from the concave inside of the arched web connecting the legs. This recess can be formed by a hole. However, it can also be created directly when forging a bearing block. The elastic pressure medium can be a rubber

or by a metal spring, in particular a helical compression spring. The pressure medium is then supported on the straight web of the swivel bracket, which is mounted in the bearing block between the curved web and the holding web, in such a way that the swivel bracket maintains its current position in every position. Uncontrolled swinging of the swivel bracket is avoided. In addition, the swivel bracket can first be swiveled into the appropriate position in order to attach a tensioning and/or pulling device. In the position of non-use, the swivel bracket can be fixed in a position that avoids any noise generation.

According to claim 4, it is possible according to the invention that the bearing block is forged.

However, it is also conceivable that, in accordance with claim 5, the bearing block is formed by punching and forming a sheet metal plate.

If, according to the invention, both legs have extensions, it is advantageous according to the features of claim 6 that the inner surfaces of the legs facing each other are arranged at an opening angle of 50° to 160°. The size of the opening angle depends on the conditions of use. The opening angle does not need to be arranged symmetrically to the vertical central longitudinal plane of the bearing block. It can certainly be shifted asymmetrically to one side or the other.

The invention is explained in more detail below using embodiments shown in the drawings. They show:

Figure 11 shows the swivel bracket of Figures 1 and 2 in the assembled state with a bearing block according to a third embodiment, partially in section.

In Figures 1 and 2, 1 designates a D-shaped swivel bracket bent and welded from a round steel. The swivel bracket 1 consists of a straight web 2, two straight legs 4 running parallel to one another attached to the ends of the web 2 via curved pieces 3, and an arched web 5 connecting the legs 4.

The forged bearing block 6 shown in Figures 3 to 5 has a U-shaped configuration. This comprises two legs 7, 8, which are connected to one another by an arched web 9. One leg 7 is enlarged beyond the end faces 10 of the bearing block 6. This forms wing-like extensions 11. The inner sides 12 of the extensions 11 are concavely curved (Figure 4).

Furthermore, it can be seen that the transitions 13 from the inner side 14 of the web 9 to the end faces 10 (Figure 3) as well as the transitions 15 from the inner side 16 of the shorter leg 8 to the end faces 10 are rounded (Figure 4). In order to reinforce these areas, two beads 17 running parallel to one another at a distance are provided on the circumference of the bearing block 6.

The plane EE (Figure 5) intersecting the end faces 18 of the legs I ₁ 8 forms an angle α of 65° with a flat outer surface 19 of the long leg 7 and an angle β of 25° with a flat end face 2 0 of the short leg 8. The plane El-El running through the outer surface 19 is at an angle Jf of 90° to the plane E2-E2 running through the end face 20.

On the inside of the legs 7, 8, recesses 21 are provided in their end areas, which serve to clamp a retaining web 22 (Figures 3 and 5). The retaining

web 22 is formed from a sheet metal plate by punching and forming. It has a leg 2 3 that can be clamped into the recesses 21 as well as two ribs 24 arranged at right angles to it and running parallel to one another. The front sides of the ribs 24 protrude beyond the plane E-E running through the front sides 18 of the legs 7, 8 (Figure 5).

When assembling the swivel bracket 1 with the bearing block 6, the web 2 is hooked into the bearing block 6 and then the retaining web 22 is clamped into the recesses 21. In this way, the swivel bracket 1 and bearing block 6 are connected to one another in a captive manner. They thus form an assembly arrangement 25 in the form of a storage or transport unit (Figures 6 to 10).

In the embodiment of Figures 6 and 7, this mounting arrangement 25 is assigned to a double-T-shaped longitudinal beam 26, which forms part of a truck not otherwise shown in detail. It is welded into the angle area between an upper horizontal flange 27 and the vertical web 28.

The installation position of the assembly arrangement 25 is determined by the outer surface 19 of the long leg 7 of the bearing block 6, which comes to rest on the side surface 29 of the web 28, and by the front surface 20 of the short leg 8, which comes to rest on the underside 30 of the flange 27. When fixing the bearing block 6, a fitter only needs to push the assembly arrangement 25 from below and upwards, pressing the outer surface 19 against the side surface 29 of the web 28, until the front surface 20 hits the underside 30 of the flange 27. The fitter now only needs to attach welding points so that the installation position of the assembly arrangement 25 is fixed. The weld seams 31 are then laid.

In the ready position according to Figure 6, the swivel bracket 1 rests with its two legs 4 on the extensions 11 of the long leg 7. The swivel bracket 1 can therefore not hit the web 2 8 of the longitudinal member 2 6 when the truck is moving.

If, however, the truck is to be lashed down on a ship, for example, the person in charge of this can simply hook a hook, connected to a chain 40 attached to the ship, into the swivel bracket 1 without having to lift the swivel bracket 1 from the web 2 8 of the longitudinal beam 2 6 with one hand. This hand is at his free disposal. As Figure 7 shows, the swivel bracket 1 can be used in a wide variety of lashing positions VP between approximately 30° and 90° to the vertical.

Figures 8 and 9 show the use of the mounting arrangement 25 consisting of the swivel bracket 1 and the bearing block 6 as well as the holding web 22 on a flat horizontal surface 32 of a plate 33 to be transported.

For this purpose, the mounting arrangement 25 is placed on the surface 32 with the swivel bracket 1 folded up onto the extensions 11 (Figure 8) at a distance from the edge 34 of the plate 33 such that no area of the mounting arrangement 25 protrudes beyond the vertical plane E3-E3 running through the front side 35 of the plate 33 into the spatial area 36.

The correct welding position of the bearing block 6 is achieved by the ribs 24 of the retaining web 22. As shown in Figure 5, these protrude beyond the end faces 18 of the legs 7, 8 of the bearing block 6 and thus ensure free spaces between the surface 32 and the outer surface 19 or the end face 20, so that after spot welding

the fitter can easily place the weld seams 37 along the legs 7, 8.

In the case of the embodiment of Figure 10, a recess 38 for receiving an elastic pressure medium 39 in the form of a helical compression spring is introduced from the concave inner side 14 of the arched web 9 connecting the legs 7, 8 of the bearing block 6. This pressure medium 39 is therefore supported on the one hand in the recess 38 and on the other hand on the outer circumference of the swivel bracket 1. The tension force of the pressure medium 39 is set so that this position is maintained in every swivel position of the swivel bracket 1 relative to the bearing block 6. Consequently, for example, when a truck is driving, the swivel bracket 1 cannot strike any area of the truck, especially a metal area, and generate an unacceptable noise level there.

The embodiment of Figure 11 shows a bearing block 6a, in which both legs 7, 8 are provided with extensions 11 on both end faces 10. The inner surfaces 41 of the extensions 11 are associated with each other at an opening angle σ which is 6 0°.

In this way, the swivel bracket 1 can swivel continuously between positions A and B in order to ensure the best lashing option in the respective application.

Otherwise, the embodiment of Figure 11 corresponds to that of Figure 10, so that a further explanation is omitted.
