Description

2254106 1 A HOLDER FOR FIXING A HOUSING OR ASSEMBLY CARRIER TO A WALL The

invention relates to a holder for fixing a housing or assembly carrier to a wall.

It is frequently necessary to fix a housing or an assembly carrier to a wall. It is possible for that purpose to use simple angle fixings which can be fixed to the housing or assembly carrier by means of one limb and to the wall by the other limb. That rigid connection suffers from various disadvantages. On the one hand the housing or the assembly carrier cannot be easily released from the wall while on the other hand the front of the housing or assembly carrier cannot be set at different angles of inclination relative to the wall.

According to the invention there is provided a holder for fixing a housing or assembly carrier to a wall, the holder comprising a base plate which is provided with angled edge walls at least at its vertical sides, a respective side plate connected to each of the vertical edge walls of the base plate and each provided at a fixing side of the base plate with an outwardly directed flange for fixing to the wall, and a respective pivot plate mounted to each side plate for limited pivotal movement about a common horizontal pivot axis and arrestable in set pivotal positions by means of arresting devices, the pivot plates being connectable to side walls or a rear wall of the housing or assembly carrier or themselves forming the side walls or the rear wall of the housing or assembly carrier.

With such a device the front of the housing or assembly carrier can be set at different angles of inclination relative to the wall and the spacing of the rear side of the housing or assembly carrier relative to the wall can be altered in order to facilitate access to the rear of the housing or assembly carrier.

With such a configuration, the base plate determines the spacing of the side plates and the pivot plates and in that way provides for adaptation to the housing or assembly carrier to be mounted in position, with its fixing means. By virtue of the limited,pivotability of the pivot plates on the side plates, it is possible to alter the inclination of the front of the housing or assembly carrier relative to the wall. The set pivot position is fixed by the arresting devices. By virtue of the possibility of pivoting the housing or assembly 2 carrier, it is also possible for example for the spacing of the lower edge of' the housing or assembly carrier from_ the wall to be reduced or increased and this can facilitate access to the rear side of the housing or assembly carrier for the connection of lines or cables.

Preferably the side plates are screwed to the vertical side walls of the base plate and have their wall fixing flanges in mirror image relationship.

Advantageously the fixing of the base plate with the side plates to the wall is improved by providing the wall fixing flanges of the side plates which are connected to the vertical side walls of the base plate to terminate flush with the free edges of the bent sides of the base plate.

An embodiment in which the housing or assembly carrier is screwed to the pivot plates provides that the end edges of the pivot plates, which are remote from the base plate, are provided with outwardly directed housing fixing flanges to which the rear wall of the housing or the assembly carrier is screwed and that the two pivot plates are of mirror image configuration. The housing fixing flanges which are directed outwardly, that is to say which face away from each other, facilitate the mounting of screw connections in that arrangement.

A reduction in the number of components can be achieved if the pivot plates are formed integrally with the side walls or the rear wall of the housing or the assembly carrier.

For limited pivotal mounting and arresting of the pivot plates, an embodiment provides that the side plates carry suspension pins which define the horizontal pivot axis, that the pivot plates have L-shaped suspension slots and can be suspended thereby on the suspension pins of the side plates and that the side plates carry arresting devices, are in the form of arresting screws outside the suspension pins and are guided in an arcuate guide slot, provided with an insertion slot, in the associated pivot plate, and can be clamped thereagainst. That arrangement provides in a simple manner that the kde plates each carry a respective nut which is accessible through a bore in the respective side plate and into which the associated arresting screw can be screwed, each arresting screw bearing against the associated pivot plate outside the respective guide slot.

If it is additionally provided that the base plate has fixing -1 3 bores, the base plate then affords further options. Thus, in accordance with an embodiment, the base plate can be used for mounting at least one C-shaped mounting rail or similar carrier rail on the front side of the base plate, which is remote from the fixing side. 5 Devices for preventing a pulling load from the being applied to cables, for example, can be mounted on the above-mentioned mounting rail. The mounting rail is preferably of a C-shaped profile. The parts required for the holder can be produced easily and inexpensively if the base plate, the side plates and the pivot plates are produced in the form of stamped bent portions from sheet metal.

The invention is diagrammatically illustrated by way of example in the accompanying drawings in which:

Figure 1 is a front view of a holder according to the invention comprising a base plate, two side plates and two pivot plates; Figure 2 is a front view of part of the holder with a mounting rail fixed on the base plate; Figure 3 is a side view of the holder viewed in the direction indicated by arrow III in Figure 1; Figure 4 is a view in section through the holder taken on line IV-IV in Figure 1; Figure 5 is a side view on an enlarged scale corresponding to the view shown in Figure 3, with a pivot plate in a suspension engagement position; and Figures 6 and 7 are side views showing two limit positions of pivotal movement of the pivot plate.

Referring to the drawings, a base plate 11 shown in Figures 1 to 4 is provided at all of its four sides with bent edge walls 12 and 13, the side edge walls 12 extending vertically and the upper and lower edge walls 13 extending horizontally. The base plate 11 has rows of fixing bores 14 therein which, as shown in Figure 2, can be used for fixing a Cshaped module rail 15 or similar carrier rail to the base plate 11. The edge walls 12 and 13 terminate with their free edge surfaces in one plane. Side plates 20 and -20' which are of mirror image configuration are screwed by screw connections 21 to the vertical side edge walls 12 of the base plate 11. The side plates 20 and 20' include outwardly angled wall flanges 22 and 221 which have fixing bores 23 and 23' through which fixing means can pass to secure the side 4 plates to a wall, the fixing flanges lying flush with the free edge surfaces of the edge walls 12 and 13 of the base plate 11 and defining therewith the fixing side.

The module rail 15 is fixed on the front side of the base plate 11, which is remote from the fixing side, and is in the form of a portion of a C-shaped profile. It can be used, inter alia, for mounting cable clamping devices for relieving cables of a pulling load thereon.

The side plates 20 and 20' each carry a horizontal pivot pin 32 which together define a pivot axis and spaced therebeneath a nut 37 and 371 each of which is accessible by way of a bore, for screwing in an arresting screw, as arresting devices 33 and 33'. The nuts 37 and 37' are welded to the side plates 20 and 201 which, like the base plate 11 and pivot plates 30 and 30', can be produced in the form of stamped bent portions from sheet metal. The pivot plates 30 and 301 are once again of a mirror image configuration and are suspended by L-shaped suspension slots 34 on the pivot pins 32 on the side plates 20 and 20'. In the illustrated embodiment the pivot plates 30 and 30' bear against the outer sides of the side plates 20 and 201, which face away from each other. The pivot plates 30 and 30' are also provided with guide slots 35 which have an insertion slot and which guide the arresting screws which are used as the arresting devices 33 and 33'. The arresting screws are screwed into the nuts 37 and 37', and bear against the pivot plates 30 and 30' so that the pivot plates 30 and 30' can be clamped to the side plates 20 and 30' in order to arrest them in a set pivotal position.

The end edges of the pivot plates 30 and 30', which are remote from the base plate 11, are angled outwardly to form housing fixing flanges 31 and 311 and are provided with fixing bores 36 and 361. The housing fixing flanges 31 and 31' can be screwed directly to the rear wall of a housing or an assembly carrier 10.

The pivot plates 30 and 30' could also be directly screwed to side walls of the housing or assembly carrier 10, without utilising the housing fixing flanges 31 and 31'. It would also be possible for the side walls of the housing or assembly carrier 10 to be made integral with the pivot plates 30 and 30' in order to reduce the expenditure on components.

As Figure 5 shows, the pivot plates 30 and 30' which are connected to the housing or assembly carrier 10 are so oriented that the pivot pins 32 can be introduced into the suspension slots 34 in the pivot plates 30 and 30'. The arresting devices 33 and 33', that is to say their arresting screws, are also aligned with the insertion slots of the arcuate guide slots 35 in the pivot plates 30 and 301 and are introduced into the guide slots 35 by a downward movement of the pivot plates 30 and 30'. The pivot plates 30 and 30' are maintained in the suspension position on the side plates 20 and 20' by virtue of the weight of the housing or assembly carrier 10 itself.

As Figures 6 and 7 show, the housing which is suspended in that way and f ixed to the wall by way of the pivot plates 30 and 301 and the side plates 20 and 20', or the assembly carrier 10 which is fixed to the wall, can be moved between two limit positions in respect of pivotal movement. By tightening the arresting screws, it is possible for it to be arrested in any desired pivotal position between those two pivot limit positions.
