Description

The invention relates to a display module to be attached to a mast with two stable module half shells with convex curved Outer walls and at least one support bracket on the mast can be attached and to which the module half-shells can be attached. The Display module is for example for a bus or tram stop usable without being limited to this application. The Display modules according to the invention can also contain other information such as information about companies housed in a building and Specify authorities, or serve as a guide, for example.

The display modules of the type under consideration are usually flat Sheet metal elements are used, which are either painted with information or are printed or - designed as a frame - foils with information contain. When such flat display modules are attached to a mast are usually kept quite small, so that the Information can only be read up close. large-scale Display modules are - because they withstand strong wind loads must - usually not attached to a mast for reasons of strength, but screwed into a frame that the display modules gives necessary stability. The framework is often for one predetermined number of display modules provided only by this can be enlarged that the previous frame by a new one Frame of a different size is replaced.  

US 52 12 898 discloses a display module that has two flat, contains elastic plates that only when they reach around a mast and tied together at the edges in this position, one assume an arched shape. The plates are Bolted profiles and with elbows in tongues from upper U- Profiles hung, which in turn by means of metal straps on Mast are attached. Should the curved Underline the display panels on the lower U profiles that the Display module does not point exactly in the desired direction, the Plates are unscrewed again, whereupon the lower strap loosened and tightened again in a new orientation of the U-profiles, so that the display module can be reattached.

DE 690 23 453 T2 (corresponds to EP 422 772 B1) discloses a display module according to the Preamble of claim 1. This display module is rotatable on the mast on which it is axially defined by an upper and a lower clamp is held.

GB 2 208 450 A discloses one to be attached to a mast Display module, which consists of two dimensionally stable module half shells with convex curved outer walls, with the module half-shells on their upper and lower flat end wall each one have semicircular contact surface for the mast. The module Half shells are screwed together so that they make up the mast pinch between them.

The present invention has for its object a display module to indicate that quickly and easily in the manner of a mast can be attached that the display module is exactly aligned.  

This object is achieved by the features of Claims 1 and 4 solved.

Advantageous developments of the invention are in the subclaims characterized.

The display module according to the invention preferably has two in Injection molding process made of plastic, convex curved Module half shells, which are opposite to a body with two the, convexly curved outer surfaces are composed, whereby the module half-shells hold the mast between them, the one in the middle runs through the display module. The module half shells are included preferably screwed together.

The convex, generally lenticular shape in horizontal section of the display module has the consequence that the wind pressure is considerable is reduced, so that the stability of one with preferably several Display modules equipped mast is significantly increased. Consequently can according to the invention on a relatively slim mast Display modules of considerable size can be attached without such a elaborate mast anchoring is required, as in the case of level Display modules would be necessary. The slightly curved outer surfaces of the display module, which is preferably uniaxial about a vertical axis are curved, are also clearly visible from a greater distance bar, if the viewer is not facing the display module, but looks at it from a laterally offset position from which flat display elements are hardly noticed.  

The two module half-shells preferably have an identical one External shape, so that the display module sym to its central plane has metric form, but the invention is not limited to this.

In the fastening position, the display module therefore preferably has two opposite wall surfaces curved around a vertical axis, which have such a large radius of curvature that the viewer can see the Be can read the writing or marking of the display module well if he is in front of the display module. The module half shells also have in the mounting position at the top and bottom on the edge of the convex vertical Wall surface level end walls, which are straight between the extend lateral edges so that when assembled of the display module, its top and bottom with the exception of Opening through which the mast passes is closed.

According to the two module half-shells are at least one, preferably attached to two clamps attached to the mast, which in turn are tightened so tightly on the mast that the Display module practically no longer rotated when assembled can be. With display modules of low height, the arrangement can be a mounting bracket should be sufficient, while larger for display modules Height two support clamps are provided, which the module half-shells in hold their top and bottom. The brackets are the same like the module half-shells, preferably made by injection molding Made of plastic.

It is further provided according to the invention that each mounting bracket consists of two with a hinge hinged support clamp- Halves exist. On the side facing away from the hinge  Ends are detachable according to a further proposal of the invention Snap fasteners provided, preferably molded, with which the Carrying clamp is first so attached to the mast that it is there held, but is still rotatable about the angular position of the mounting bracket and so that the alignment of the module Half shells on a curb to allow it to be in all Usually in the area of a bus or tram stop next to the mast located. The alignment of the mounting bracket and thus the display module will be described in more detail below.

There are preferably two spaced one above the other Snap locks are provided, each protruding Have locking arm with a sawtooth-like tooth, for example can, which in corresponding recesses on the edge of each other half of the clamps can intervene. There are several each Locking positions possible to ensure that when occurring Tolerances of the mast diameter of each bracket using the Snap fasteners can be fastened so that they are final The screw connection on the mast is held at the intended height. It will again emphasizes that the snap closures are only temporary Have a holding function, and that the final attachment of the bracket by preferably tightening a single locking screw, which can be provided between the snap locks.

It is also proposed with great advantage that each support bracket Half molded hubs that are perpendicular to the median plane of the Carrying clamp and the assembled module half-shells run and in the holes trunnions can be used, the corresponding places and in equal numbers on the inside of the Module half shells are molded. The trunnions extend naturally also perpendicular to the median plane mentioned. The  Arrangement can also be made the other way around by the Support clamp halves projections, e.g. B. trunnion, and on the module Half-shell recesses, e.g. B. hubs are formed.

The module half-shells are thus attached to the support clamp Halves attached that their trunnions in the holes of the Halves of the clamp are inserted. Then the Module half shells screwed together, for which purpose on the inside of the Module half-shells dome can be molded using an internal thread included, while on the other module half-shell Through holes in the assembled state with the Female threads in alignment through the outer wall for insertion can be formed by screws. The screw connection can also done in a different way, it being essential that the module Half shells do not have to be firmly clamped against each other, since the immovable attachment to the mast by tightening the Carrying clamps are made.

As mentioned, the mounting bracket is after its exact positioning on Mast preferably by means of a single locking screw on the mast tightened, which is why preferably halfway up the clamp on the Hinge opposite side a metal sleeve with internal thread in an edge web of a clamp half can be embedded, the one Through hole in the edge web of the other half of the clamp opposite.

As already mentioned, according to the invention, the display modules in each case by means of two spaced apart support clamps on the mast attached if it is not particularly small display modules is. This is associated with the problem that the two brackets are attached to the mast at exactly the right distance from each other  so that in the upper and lower area of the module half-shells molded support pins fit into the hubs of the two support clamps.

According to the invention this problem is solved in that the two Carrying clamps in the fully assembled state, d. H. With inserted hinge pin with one half of a clamp in one of the two module half shells can be used by the protrusions the module half-shell into the holes in the hubs of this support clamp Intervene halves. In this state, the two support clamps Halves preferably with two small ones in the module half shells countersunk auxiliary screws attached. The two halves of the clamp are used so that the hinge pins cannot fall out, what is achieved in that the head of the hinge pins each in the area of the horizontal upper or lower end wall of the Module half-shells are located.

After inserting the support clamp halves into one of the two modular The two brackets are attached to the mast with half-shells, whereby they are exactly the prescribed distance apart. The The clamps are now attached to the mast using their snap locks attached that they can not slide down, but still around the mast are rotatable.

To align the support clamps in the desired direction, e.g. B. on the roadside is now a guideline in the form of an elongated, straight rod or board with its trunnion into the hub of one exposed half of the support clamps used, the guide line the Alignment of the center plane of the display module to be mounted reproduces. By swiveling the guide around the mast in one to the curb edge parallel position, the two brackets with the module half shell held on it aligned.  

Then the two brackets by tightening each a locking screw immovably attached to the mast, so that their Angular position can no longer be changed. Then the second module Half shell placed on the two exposed halves of the support clamp, in which their trunnions in the hubs of the half-clamp are inserted, and the module half shells are joined together screwed without being firmly clamped together.

In this way, the display module according to the invention can quickly and simply attached to a mast, with the exact Alignment is not associated with any difficulties. For the production the support clamps is only one because of their short axial extension small tool required, which would not be the case if two Clamps connected by a central tubular part would. The positioning at the correct distance from each other takes place on the above-mentioned manner according to the invention.

Due to the special design of the support clamps and the attachment the module half-shells on the support clamps screwed to the mast it is ensured that the display modules according to the invention always can be attached to the mast in a torsion-proof manner, even if the Vary mast diameters in the order of a few mm.

The display modules according to the invention, which are preferably sprayed Casting methods are made of plastic, are extremely robust and withstand all weather influences permanently. Because of your curved shape, the wind pressure acting on them is considerable reduced so that they are safe from a relatively thin mast are to be kept. They are quick and easy to attach and so are easy to dismantle. Because of their domed shape, they are visible from afar, so that even distant people  Signal the presence of a stop.  

The outer wall of the module half-shells can, for example Cross-sectional shape of a large diameter circular arc or of an ellipse section, with further curved or convexly curved shapes are within the scope of the invention.

An embodiment of the invention is described below with reference explained in more detail on the drawing. Show:

Figure 4 is a horizontal section through the supporting clamp of Figure 2 taken along a line BB..;

Fig. 5 is a horizontal section through the mounting bracket according to FIG. 2 along a line CC and

Fig. 6 is a perspective view of a straight edge.

In Fig. 1, a module half-shell 1 is shown, which has a uniaxially curved outer wall 2 and an upper and a lower end wall 3 , 4 . The module half-shell 1 is stiffened by transverse walls 5 and longitudinal walls 6 , which are integrally formed on the walls 2 , 3 and 4 . This means that the module half-shell, which is made in one piece from plastic by injection molding, is extremely dimensionally stable.

In the upper and the lower end wall 3 , 4 , a semicircular recess 7 is provided, from which an upper and a lower collar 8 and 9 ( FIG. 2) each protrudes a mounting bracket 10 in the assembled state on the mast, which is explained in more detail below is explained.

On the inside of the curved outer wall 2 four projections 11 are also formed in the vicinity of the upper and lower end wall, which extend perpendicular to the central plane of a display module composed of two module halves 1 . These projections 11 , hereinafter referred to as support pins, are used to fasten the module half-shells 1 to each support bracket half by inserting the support pins 11 into halves formed on the support bracket halves 12 . This is also explained in more detail below.

In addition, 1 dome 13 a are formed on the inside of the module half-shells, into which sleeves with an internal thread can be inserted. At corresponding points of the associated other module half-shell there are through holes through the outer wall into which screws can be inserted which engage in the dome 13 in order to screw the two module half-shells 1 together when they are attached to two support shells attached to the mast len are attached.

In Figs. 2 to 5, a supporting clamp is shown, two of which are used to two module half-shells shown in Fig. 1 to be mounted on a mast. The mounting bracket 10 consists of two mounting bracket halves 13 , each of which extends over a circumference of 180 ° and are connected to one another in an articulated manner by means of a roller hinge 14 . The associated hinge pin 15 is indicated by dashed lines in Fig. 2.

At each supporting clamps-half 13 are formed four hubs 16, which in pairs are at the same height and extend perpendicularly to the center plane or parting plane 17 of the supporting clamp 10th The hubs have the bores 12 already mentioned, into which the support pins 11 of the module half-shells 1 fit essentially in a form-fitting manner. The trunnions 11 , like the bores 12, have a slightly tapered shape in order to facilitate the introduction of the trunnions 11 into the bores 12 .

Between the pairs of hubs 16 spaced apart in the longitudinal direction 18 there is a bore 19 for a locking screw 20 at a medium height of the mounting bracket 10 , which can be screwed into a sleeve 22 with an internal thread inserted into an edge web 21 of the other mounting bracket half 13 the support clamp 10 immobile to tighten on a mast.

Between the position of the locking screw 20 and the upper and lower hub 16 there is a molded snap closure 23 ( FIG. 5) with which the clamp 10 can be attached to a mast in such a way that it is held at the selected height, but still around the mast can be rotated to align the display module with the course of the roadside. The snap closure 23 contains a molded arm 24 with a z. B. roof-shaped projection 25 which engages in an equally roof-shaped toothing 26 on the other bracket half 13 . The engagement is maintained by the spring force of the snap arm 24 .

By forming several teeth in the toothing 26 , for example, three or four different locking positions are possible, so that the mounting bracket 10 can be attached to masts of different diameters. It is emphasized once again that the snap locks 23 only have a temporary holding function, and do not serve over the final, rotationally fixed fastening of the support clamps on the mast.

Fig. 6 shows a guide 27 in the form of an elongated, straight rod or board, on which projections or pins 28 are formed or fastened on a side surface, which correspond in their arrangement and shape to the support pins 11 of the module half-shells 1 . This Richscheit 27 is used to attach the clamp 10 in such an angular position on the mast that the attached module half-shells 1 point in the desired direction Rich.

The display module according to the invention is attached to a mast in the following way: first, two brackets 10 are assembled with a module half-shell 1 in such a way that the four hubs 16 of each one bracket half 13 hold four trunnions 11 of a module half-shell. The arrangement is such that the hinge pin 15 is arranged with its head near the upper or lower end wall 2 , 3 of the module half-shell, so that it is ensured that the hinge pin 15 can not fall out of the roller hinges 14 ,

The brackets 10 are now attached by means of their snap fasteners 23 to the mast, wherein they are kept at the desired height, but are still rotatable.

In the four hubs 16 of one of the two exposed Tragschel len halves 13 , the pin 28 of the straightener 7 are now inserted, so that the straightener 27 indicates the position of the central plane of the display module. The module half-shell 1 attached to the mast can then be rotated into its desired position with its two clamps.

Then the locking screw 19 is tightened so that the two clamps are immovably attached to the mast.

Then the second module half-shell 1 is plugged onto the two exposed half-clamps, whereupon the module half-shells are screwed together without having to be firmly clamped to one another, since the fastening function on the mast is carried out by the clamps 10 .

As shown in FIG. 2, a collar 8 , 9 is formed on the support bracket 10 in the axially upper and lower area, which tightly encompasses the mast. The collars 8 , 9 have serrations 29 which are matched to one another so that the serration on the underside fits exactly into the serration on the top. In this way, a plurality of display modules can be arranged one above the other at a precisely predetermined distance, their angular position on the mast being the same.

The support clamps 10 can be produced using small tools, which means that their production costs are relatively low. Nevertheless, the provided for mounting a display module NEN two mounting brackets in a simple manner at an exact distance from each other, as described above.
