Benefits of technology
[0006] Thus, it is the object of the present invention to provide a supporting device, particularly for variable message signs, which may easily be mounted in any spatial arrangement, in which repair work of the signal transmitters or their exchange can easily be carried out by one single technician in a simple manner without using any tool.
[0008] By the two-piece construction of the supporting device and the pivotal arrangement as well as the connection of the two supporting frames that can easily be released again, a supporting device has been created in which a first installation is basically restricted to the attachment of the first supporting frame, whereas the adding of the second supporting frame is extremely simple and can therefore be carried out by one single assembler. Repair and exchange work is also possible without having to remove the entire device from its place, since in a hanging state of the second supporting frame either the signal transmitters can be replaced and exchanged or the entire second supporting frame can be exchanged in a simple manner.
[0011] The bracket advantageous comprises a bolt in the area of its upper end, said bolt being insertable into at least one slot formed in the first supporting frame, wherein a first pivotal locking means for fixing the bracket prevents the bolt from exiting after its insertion into the slot. With all remaining locking means being removed it is thus also ensured that the second supporting frame maybe brought from the latched into the down-hanging position in a simple manner.
[0013] The bracket comprises a head preferably on its upper end, said head having a tapered front end where first and second edges of the head meet. Due to this design it is easily possible to provide a second locking means which is easily operable to cooperate with both edges.
[0015] In a preferred embodiment, a leaf spring is arranged between the roller and a transverse rail of the first supporting frame, said leaf spring pressing the roller downwards, which causes the roller to be pressed into its locking position and whereby an unlocking of the second supporting frame caused by vibrations is prevented.
Problems solved by technology
In display devices of this type, the supporting frame has usually been fixedly mounted on the tunnel ceiling, which in the case of initial assembly, in the case of repair work and when exchanging individual display segments leads to significant problems.

Embodiment Construction
[0024]FIG. 1 shows a first embodiment of the supporting device 1 according to the invention. The supporting device 1 is composed of a first supporting frame 3 and a second supporting frame 5. The first supporting frame 3 is durably attached to the subsurface by means of conventional attachment means, wherein the invention is particularly suitable for ceilings of tunnels etc., although the use of the supporting device 1 according to the invention is also conceivable in any other spatial arrangement. The first supporting frame 3 usually comprises two angular rails 7 arranged at a certain spacing to one another, said rails being connected by respective transverse rails. The outer frame generated thereby may be supplemented additionally by a rear wall 11, although this is not required. The angular rails 7 and the transverse rails 9 together form an accommodation space into which the second supporting frame 5 may be inserted. The second supporting frame 5 has a shape similar to that of t...

The supporting device for signal transmitters includes a first flat supporting frame, which may preferably be attached in parallel to a ceiling of a tunnel, and a second flat supporting frame adapted to accommodate signal transmitters, wherein the second supporting frame is pivotally connectable to the first supporting frame at a first end of the supporting device via first connecting means, and is detachably fixable to the first supporting frame at a second end of the supporting device via second connecting means.
Description
RELATED APPLICATION [0001] This application claims the benefit of DE 20 2004 016 565.1, filed Oct. 26, 2004, the contents of which are incorporated herein. FIELD OF THE INVENTION [0002] The present invention refers to a supporting device for signal transmitters by the aid of which relatively heavy mechanical and electronic units may be attached particularly to ceilings. [0003] Supporting devices of this kind have been known since the introduction of mechanically or electro-optical variable message signs and traffic management systems. Usually, supporting devices of this type are arranged perpendicularly at respective masts or bridge piers or laterally on tunnel walls so that the road users may well perceive from a far distance the signal transmitters located within the supporting device. BACKGROUND OF THE INVENTION [0004] EP 0 917 703 B1 discloses an optical display device, which provides significant advantages with respect to the dimensions, in that the supporting device is aligned...
