Designation: Fastening device for signs that can be attached to sign posts or light poles, such as routing signs

Description

The invention relates to a fastening device for a sign on a preferably curved support structure having a longitudinal axis, such as a sign post, light pole or pipe, with a substantially rectangular intermediate plate with two edge-side legs which are bent essentially at right angles from opposite sides of the intermediate plate to the rear of the intermediate plate and which come to rest on the support structure, wherein the intermediate plate has at least two holes arranged essentially along a central longitudinal axis for receiving connecting means, such as screws, countersunk screws or the like, with which the sign can be releasably secured against the front side of the intermediate plate.

Such fastening devices are used, for example, to fix information signs to sign posts which are used to route underground supply lines, such as water or gas lines, or parts of such supply lines.

A fastening device with the features mentioned above for fastening information signs to supporting structures, in particular sign posts, has, for example, a U-shaped bracket and a yoke, the front of which serves as a contact surface for the information sign. The yoke is designed as a substantially rectangular intermediate plate, with two opposite sides, in this case the broad sides, having legs that are bent essentially at right angles to the rear and come to rest on the sign post.

Another known way of attaching the yoke to the sign post is to place a perforated band around the sign post and secure it with a perforated band clamp, whereby the connecting elements of the perforated band clamp engage through holes in the yoke. The information sign is then attached to the sign post using thread countersinking elements, which are screwed through holes in the information sign onto the threads of the bracket ends or the connecting elements of the perforated band clamp.

A disadvantage of these known fastening devices is that the bracket and also the yoke must be adapted to the respective individual diameter of the supporting structure or the sign post.

It is also already known to attach route signs to light poles using a tensioning strap, whereby the tensioning strap is stretched around the light pole and a holding part that can be connected to the tensioning strap or perforated strap carries the information sign. This additional fastening device has the disadvantage that the fitter always has to carry different tensioning devices with him in order to be able to meet the different requirements with regard to installation.

From DE 35 03 248 A1, an arrangement for fastening signs by means of sign supports to a supporting structure, e.g. a pipeline, is also known, wherein the sign support has a base web for contact with the wall surface and at least one side wall rising from the base web. The side walls are adjoined by front flanges running parallel to the base web, which define a mounting plane directed towards the viewer for fastening the identification plate. On the base web or in the area of recesses in the side walls

clamping elements, e.g. clamping bands, pipe clamps or the like, so that the sign holder can be attached to the wall surface either in a vertical or horizontal orientation of the front flanges.

DE 199 01 025 A1 describes a variable-use sign clamping device, whereby the sign is secured to a sign holder using elastic locking bolts and the sign holder itself has elongated holes. This allows the sign holder to be attached to the supporting structure, e.g. a light pole, a street lamp or a tree, using a tensioning strap, a tension spring or a plastic or textile strap.

Based on this prior art, the present invention is based on the object of developing a fastening device with the features mentioned at the beginning in such a way that a routing or information or similar sign can be easily attached to a curved support structure, e.g. a sign post, without the need for individual adaptation of the fastening means to the diameter of the sign post. According to a secondary aspect of the invention, the fastening device should not only be used to attach signs to sign posts, but also to light poles, whereby the installation of the information sign should be extremely quick and easy in both cases.

The main object of the invention is achieved in the fastening device with the features mentioned at the outset in that the central longitudinal axis of the intermediate plate essentially encloses a right angle with the sides of the intermediate plate having the angled legs.

While in the prior art the intermediate plate designed as a yoke is also fixed in sign posts transversely to the longitudinal axis of the sign post by means of a U-shaped bracket, a perforated band or a tensioning band, the invention provides that the intermediate plate can be fixed to the support structure with its central longitudinal axis essentially aligned with the longitudinal axis of the support structure. In the case of a sign post, the intermediate plate is aligned with its central longitudinal axis approximately parallel to the longitudinal axis of the sign post, with the angled legs then resting vertically on top of each other on the outer wall of the sign post. This makes it possible for the intermediate plate and the sign to be fixed to the sign post without using a U-shaped bracket, a perforated band or other tensioning band, by driving the connecting means, in particular screws, through aligned holes in the sign and the intermediate plate into the wall of the sign post or another pipe. Special fastening devices that would have to be adapted to the individual diameter of the sign post or pipe are no longer required.

According to a first advantageous embodiment of the invention, the essentially rectangular intermediate plate has a broad side and a narrow side, the length ratio of which is approximately between 2:1 and approximately 4:1, preferably approximately 3:1, wherein the legs are angled from the narrow sides.

In particular, the intermediate plate can have dimensions of approx. 12 cm x approx. 4 cm, which has proven to be useful in practice in terms of stability. The thickness of the plate can be approx. 4 mm. The plate is preferably made of aluminum, stainless steel or another weatherproof material.

Furthermore, it has proven to be advantageous that the narrow side and leg length have a length ratio of approximately 5:1 to approximately 1:1, preferably approximately 3:1, with the legs preferably extending along the entire narrow side of the intermediate plate. In this respect, it is possible to form the intermediate plate with the legs in one piece, with the latter being formed by bending the edge areas of the narrow sides.

According to another embodiment of the invention, the legs have a substantially V-shaped cutout, which is preferably arranged symmetrically with respect to the central longitudinal axis. These substantially V-shaped cutouts ensure automatic adjustment of the intermediate plate to posts or tubes with different external diameters.

According to another advantageous development of the invention, the intermediate plate has sleeves or bushings that protrude from the rear of the intermediate plate at a right angle to accommodate the connecting means. These sleeves or bushings can be fastened, for example, in holes in the wall of the intermediate plate and ensure that the fastening means, e.g. the screws, are guided as soon as they are inserted through the holes in the intermediate plate or the shield.

Preferably, the length of the sleeve or bushing is designed such that it corresponds to approximately half the leg length, or is dimensioned such that the free end of the sleeve or bushing comes into contact with the supporting structure when the intermediate plate is mounted. In this respect, it is possible for the sleeve or bushing to also serve as a spacer that prevents or reduces bending of the intermediate plate when the connecting means are tightened.

According to a particularly advantageous, independent embodiment of the invention, which can also be used independently of the aforementioned measures, the intermediate plate preferably has loop-forming brackets on the edge in a central area of the broad sides, whereby a tensioning strap can be passed through the loops. This embodiment allows the intermediate plate according to the invention to be fastened not only to a hollow-walled sign post or a pipe, but also to other curved support structures that are solid or have very thick walls, e.g. light poles or the like, and where it is not easy to drive the fastening means into the wall of the support structure. In such applications, the intermediate plate can be secured to the support structure by means of a tensioning strap, a perforated strap or similar holding part, which is placed around the support structure and passed through the loops of the intermediate plate. The connecting elements, e.g. the screws, then no longer serve to attach the intermediate plate to the supporting structure, but only to attach the sign to the intermediate plate, for which purpose, for example, nuts that interact with the screws can be provided.

In this respect, it is advantageous for light poles and the like that the intermediate plate can be releasably fixed to the supporting structure with a tensioning strap.

With regard to sign posts and other, essentially thin-walled support structures, it is particularly advantageous that the intermediate plate can be fixed to the support structure using connecting means, e.g. screws, which can be driven into a wall of the support structure.

Finally, it is advantageous that the sign can be attached using fasteners such as screws, countersunk screws, etc.

The like can be fixed to the intermediate plate, preferably detachably, wherein the connecting means are inserted through holes in the shield which are aligned with the holes in the intermediate plate.

Further aims, advantages, features and possible applications of the present invention will become apparent from the following description of an embodiment with reference to the drawings. All described and/or illustrated features form the subject matter of the present invention, either individually or in any meaningful combination, regardless of their summary in the claims or their reference back to them.

curved support structure 14, which has a longitudinal axis 16. The support structure 14 is designed as a sign post in the exemplary embodiment, but it can also be a light pole, a pipe or the like.

The fastening device 10 comprises a substantially rectangular intermediate plate 18 with two edge-side legs 22, 24 which are angled essentially at right angles from opposite sides 40, 42 of the intermediate plate 18 to the rear side 20 of the intermediate plate 18 and which come to rest against the support structure 14 when the fastening device 10 is in the assembled state. Furthermore, at least two holes 28, 30 are arranged essentially along a central longitudinal axis 26 on the intermediate plate 18 for receiving connecting means 32, e.g. screws, countersunk screws or the like, with which the sign 12 can be releasably secured against the front side 38 of the intermediate plate 18. The central longitudinal axis 26 encloses an i. w. right angle with the sides 40, 42 of the intermediate plate 18 having the angled legs 22.

Due to these measures, the intermediate plate 18 of the fastening device 10 according to the invention is no longer fastened to the support structure 14 with its central longitudinal axis 26 transverse to the longitudinal axis 16 as in the prior art, but rather the central longitudinal axis 26 and the longitudinal axis 16 are essentially parallel or aligned with one another in the assembled state. This also means that the holes 28, 30 are aligned with the longitudinal axis of the support structure 14.

The essentially rectangular intermediate plate 18 has a broad side 44, 46 and a narrow side 40, 42, the length ratio of which is between approximately 2:1 and approximately 4:1, preferably approximately 3:1. The legs 22, 24 are arranged on the narrow sides 40, 42 of the intermediate plate 18 and

this is angled towards the rear side 20. Furthermore, it is provided that the narrow sides 40, 42 and the leg length of the legs 22, 24 have a length ratio of approximately 5:1 to approximately 1:1, preferably approximately 3:1, wherein the legs 22, 24 preferably extend along the entire narrow side 40, 42.

As can be seen from Figures 1 and 4, for example, the legs 22, 24 have a substantially V-shaped cutout 48, 50, which is preferably arranged symmetrically with respect to the central longitudinal axis 26. This means that the intersection point of the two V-legs of the cutout 48, 50 is arranged essentially on the central longitudinal axis 26 or is aligned with it.

In particular, it can be seen from Figure 2 that the intermediate plate 18 has sleeves or bushings 52, 54 which protrude from the rear side 20 essentially at right angles and which serve to receive and guide the connecting means 32, for example the screws 34, 36. The length of the sleeve or bushing 52, 54 is approximately half the length of a leg 22, 24. Alternatively, the length of the sleeve or bushing 52, 54 can also be dimensioned such that the free end of the sleeve or bushing 52, 54 comes to rest against the support structure 14 when the intermediate plate 18 is in the assembled state.

Figures 1 and 2 show a further alternative embodiment of the intermediate plate 18, which preferably has edge loops 56, 58 in a central region of the broad sides 44, 46, which are formed by brackets 60, 62. These brackets 60, 62 or loops 56, 58 are preferably produced by punching in the edge region of the broad sides 44, 46. A tensioning strap 64 can be passed through these loops 56, 58, as is indicated by dashed lines in Figures 1, 4, for example.

In this respect, it is provided in particular for light poles or the like that the intermediate plate 18 can be releasably secured to the support structure 14 with a tensioning strap 64. For sign posts or similar thin-walled support structures 14, it is also possible to mount the intermediate plate 18 without using a tensioning strap 64, in which case the intermediate plate 18 can then be releasably secured to the support structure 14 with the connecting means 32, e.g. the screws 34, 36, in which case the screws 34, 36 are driven into a wall 70 of the support structure 14.

In any case, the plate 12 is releasably secured to the intermediate plate 18 by means of the connecting means 32, e.g. the screws 34, 36 or countersunk screws, wherein the connecting means are inserted through holes 66, 68 of the plate 12 which are aligned with the holes 28, 30 of the intermediate plate 18.

There are therefore two alternative designs for fastening the sign 12 to the support structure 14. On the one hand, there is the possibility of securing the sign 12 with the intermediate plate 18 to the support structure 14, in particular a sign post, by inserting the screws 34, 36 through holes 66, 68 and 28, 30 in the sign 12 and the intermediate plate 18 and driving them into the wall 70 of the support structure 14. An alternative possibility for fastening the sign 12 to the support structure 14 is that the intermediate plate 18 is secured to the support structure 14, in particular a light pole with a thicker wall 70, by means of a tensioning strap 64, the sign 12 then being secured to the intermediate plate 18 by means of the connecting means 32.
