Description

DESCRIPTION BRACKET

The invention relates to a holder for the detachable fastening of a housing of an electrical device or the like with a mounting plate which has at least one recess which is at least partially surrounded by a sliding edge which can be engaged behind by a housing projection, and at least one locking device which can be locked to the housing in its sliding position.

Such a holder is known from DE 36 25 466 C2. In this holder, recesses are formed in the side edges of a mounting plate and projections are formed between these, which can be gripped by counter projections inserted into the recesses on the rear of the housing. Furthermore, a latch protrudes from a lower edge of the mounting plate, which engages in a corresponding recess in the rear of the housing when the housing is pushed onto the mounting plate in the sliding direction. Further recesses are arranged in the mounting plate, which are used to attach the mounting plate to a wall or ceiling using screws.

The disadvantage of the previously known holder is that a large number of recesses and corresponding counter or housing projections are necessary in the respective edge area of the mounting plate or the back of the housing in order to enable a relatively firm, detachable fastening of the housing. A further disadvantage is that an additional locking recess must be arranged in the back of the housing in order to lock it into place with the locking latch. This makes the production of the mounting plate and housing relatively complex and correspondingly costly.

The invention is therefore based on the object of improving a holder of the type mentioned at the outset in such a way that it is structurally simplified for the secure fastening of a housing

This makes both the manufacture and assembly of the housing on the mounting plate faster and easier.

This object is achieved in a holder with the features of the preamble of claim 1 in that, for three-point fastening of the housing, a first and a second recess are arranged essentially next to one another in the sliding direction of the housing and a third recess is arranged in the sliding direction below or above the other two recesses between them in the mounting plate, wherein the locking device is assigned to at least one of the recesses for locking with a corresponding housing projection.

The simple three-point fastening means that only three recesses and corresponding housing projections are necessary, whereby one of the recesses is arranged between the other two recesses to ensure a more stable fastening of the housing to the mounting plate. For example, the three recesses can be arranged in such a way that they determine the corners of an isosceles triangle. This means that the first and second recesses are arranged at the ends of the hypotenuse and the third recess is arranged at the apex of the triangle. In this context, it should be noted that the three-point fastening is a minimum requirement and that additional recesses can be provided for heavier and larger housings or mounting plates.

By assigning the locking device to a recess, it can lock directly into a housing projection when the housing is in the slide-on position, so that no separate locking recess needs to be provided on the housing. A corresponding locking device can be assigned to several recesses or even all recesses.

A particularly advantageous embodiment of the invention is characterized in that the holder has a pipe holder that can be attached to a pipe on the side of the mounting plate facing away from the housing. This means that electrical devices or the like can be attached to a pipe using their housing and the holder. The pipes can

have essentially any cross-section, such as a square or a round cross-section.

In the simplest case, the locking device is designed as a spring-elastic locking hook that protrudes into the recess, which automatically engages behind the corresponding housing projection and can be deflected to release the housing projection when the housing is dismantled.

In this context, it is advantageous if the locking hook extends essentially parallel to the sliding direction. The locking hook preferably has a locking lug at its upper end, which engages behind the housing projection when the housing is in the sliding position.

To adapt to different pipe diameters or pipe cross-sections, it is possible to design the pipe holder and mounting plate separately and connect them as required. However, to simplify and speed up the manufacture of the bracket, it is advantageous if the pipe holder and mounting plate are designed as one piece, with the mounting plate being essentially flat and the pipe holder having a receiving recess that is essentially open towards the pipe. The receiving recess can be adapted to the corresponding cross-section of the pipe.

If the pipe is circular in cross-section, for example, a receiving recess that is essentially semicircular in cross-section is advantageous. To make it easy to attach the bracket to the pipe, the pipe holder can have an insertion opening for a bearing end of a half-clamp on one side of the receiving recess and a fastening device for a fastening end of the half-clamp on the other side. The bracket is installed in such a way that the receiving recess is pushed onto the pipe from one side. The bearing end of the half-clamp is then inserted into the insertion opening and the half-clamp is placed on the side of the pipe opposite the receiving recess until the fastening end of the half-clamp is on the

Fastening device of the pipe holder can be fastened, for example by screwing.

A simple embodiment of the invention is characterized in that the pipe holder is essentially U-shaped in cross section, with an insertion _opening and fastening device being formed at the free ends of the U-legs and the U-legs and U-web enclosing the receiving recess. The U-legs can protrude from the side facing away from the housing, i.e. the pipe side of the mounting plate.

The pipe side of the mounting plate could, for example, form part of the U-shaped bridge. However, to ensure a more stable attachment of the bracket to the pipe, it is advantageous if the U-shaped bridge is designed separately and is spaced apart from the side of the mounting plate facing away from the housing.

To save material and at the same time simplify fastening of the half clamp, it is also advantageous if the U-legs are essentially hollow and their interior is accessible through openings in the mounting plate.

In order to secure the half clamp with its insertion end in the insertion opening, it is advantageous to arrange a bearing projection next to the insertion opening at the free end of a U-leg, which bearing projection protrudes into the interior of the U-leg and can be inserted into a corresponding bearing opening of the half clamp.

In order to be able to attach the corresponding fastening end of the half clamp, for example by screwing it to the pipe holder of the bracket, it is also advantageous if the fastening device of the other U-leg has a hole in its free end. This can, for example, have an internal thread so that a screw can be screwed in directly.

In order to be able to use a normal nut instead of an internal thread in connection with the bore, the arrangement of a

For example, a hexagonal sleeve concentric to the bore in the interior of the

other U-leg is advantageous. A nut can be held in this sleeve so that it cannot rotate.

It is also advantageous if the nut is also fixed in the longitudinal direction of the sleeve. This can be done, for example, by the sleeve having at least two retaining projections for positioning the nut, spaced from the bore opening, running in the direction of the bore opening and inclined towards one another. In this way, the nut can be pushed through the opening in the housing side of the mounting plate until it is held by the retaining projections directly below the bore and at the same time is positioned in a rotationally fixed manner by the sleeve.

To further save material, an opening associated with the U-bar can be formed in the mounting plate.

The recesses according to the invention can be designed as openings in the mounting plate that are surrounded on all sides. Furthermore, the recesses or at least some of the recesses can be open towards the edge of the mounting plate or towards the openings in the mounting plate, opposite to the sliding direction of the housing. Such a recess can be arranged, for example, in the edge area of the opening assigned to the U-web.

In order to enable self-locking fastening of the housing projections by means of the sliding edge, it is advantageous if the sliding edge is arranged at least on one side of the recess and runs in a ramp-like manner in the sliding direction.

In order to enable the housing projection to be easily inserted into the recess, the sliding edge can have a shorter length than the recess in the sliding direction. In this way, the recess has, for example, a greater width in the sliding direction in front of the sliding edge, so that the housing projection can be easily inserted and

can then be moved in the direction of the sliding edge. If the sliding edge is designed to face the recess on one side, such a housing projection can be L-shaped, for example. The longer L-leg preferably protrudes from the rear of the housing, and the shorter L-leg serves as a housing projection for engaging behind the sliding edge. If the sliding edges are arranged on both sides of the recess, a corresponding housing projection can be T-shaped, for example, with the T-crosspiece engaging behind both sliding edges. In addition, the T-shaped housing projection can have a dovetail shape.

Depending on the length of the housing projection in the sliding direction, the locking hook is designed with a corresponding length so that it can securely grip behind the housing projection when the housing is in the sliding position. The locking hook is preferably longer than the sliding edge and is arranged essentially centrally between it and the opposite edge of the recess. Furthermore, the locking hook can be offset from the sliding edge in the direction of the tube side of the mounting plate so that there is sufficient space between the locking hook and the receiving edge to insert the housing projection.

To further stabilize the fastening of the housing to the mounting plate, the recesses can be arranged at least in pairs in the transverse direction and/or in the longitudinal direction of the mounting plate. For example, in addition to the third recess of the three-point fastening, a further recess can be arranged in the longitudinal direction of the mounting plate above or below it. In this way, the first and second recesses are arranged in pairs, for example in the transverse direction of the mounting plate and the third recess and the further recess associated with it are arranged in the longitudinal direction of the mounting plate.

For example, in order to identify the electrical devices or the like attached to the mounting plate, at least one edge of the mounting plate can have recesses set back from the plate plane for attaching a label holder.

or the like. In this way, the label carrier can be easily attached to the mounting plate in addition to the housing. In one embodiment of the label carrier, for example, a corresponding label can be inserted into it to identify the device contained in the housing or to provide other information. The label carrier has complementary attachments or the like to the attachment recesses.

In order to hold the plate carrier securely, locking projections extending essentially perpendicular to the plate plane are arranged in at least some of the mounting recesses. The mounting projections can be locked into place on the plate carrier using these.

In order to be able to attach the bracket to pipes of different diameters and cross-sections even when the mounting plate and pipe holder are made as one piece, it is advantageous if an adapter can be arranged between the pipe clamp and the pipe. This is fixed in position when the half clamp is attached to the pipe holder.

The holder according to the invention can be made of a plastic material or a metal.

In the following, advantageous embodiments of the invention are explained and described in more detail with reference to the figures attached to the drawing.

Figure 1 shows a view of a housing side 45 of a mounting plate 3 of a first embodiment of a holder 1 according to the invention. The mounting plate 3 has an approximately rectangular outline, with a number of recesses 4, 5, 6, 50 and openings 26, 27 and 35 formed in it. The recesses 4, 5 and 50 are open to an upper area of the edge 3 6 of the mounting plate 3 opposite to a sliding direction 12 for a housing to be detachably attached to the holder 1. The recesses 4, 5 are surrounded on one side by a sliding edge 10 in the sliding direction 12.

which ends at a distance from the upper edge of the mounting plate 3. Between the sliding edge 10 and an opposite edge 39 of the recess 4 or 5, a locking hook 11 is arranged as a locking device. This has a locking lug 51 pointing in the direction of the recess at its upper end.

The recesses 6 and 50 are approximately T-shaped, with the T-longitudinal web being surrounded on both sides by sliding edges 10 and the T-transverse web forming an insertion opening for housing projections shown later. Furthermore, a series of plug-in recesses 40 are formed on the upper edge between recess 4 and recess 50 and between this and the further recess 5. These are set back from the plate plane on both the housing side 45 and the tube side 14 shown in Figure 2 and are open towards the upper edge of the mounting plate 3. Locking projections 43 are arranged within the plug-in recesses 40.

The locking hooks 11 have a greater length than the length 37 of the sliding edges 10 in the sliding direction 12. The locking hooks are shorter than the total length 38 of each recess, see also Figure 2.

The recesses 4, 5 and 6 form a three-point fastening for a housing shown as an example in Figure 11, wherein the recesses 4 and 5 are arranged symmetrically to a central longitudinal axis of the mounting plate 3 and the third recess 6 lies directly on the central longitudinal axis.

Below the recesses 4 and 5, two essentially rectangular openings 26 and 27 are formed in the housing side 45 and a larger opening 35 between them. The openings 26 and 27 are connected to interior spaces 25 (see Figure 3) of a pipe receptacle 15 that is essentially U-shaped in cross section. A rear side of a receptacle recess 16 (see Figures 2 and 3) is visible through the opening 35. The receptacle recesses 56 are open to the opening 35.

The recesses 4 and 5 are arranged in pairs in the transverse direction 46 and the recesses 56 are arranged in pairs in the longitudinal direction 47 of the mounting plate 3.

Figure 2 shows a view of the tube side 14 of the mounting plate

3 according to Figure 1. The same symbols indicate the same components and are only partially mentioned.

It can be seen that the slide-on edges 10 are set back from the plate plane of the mounting plate 3 on the tube side 14, while in the plate plane of the housing side

4 5 are arranged flush with the surface according to Figure 1. At their front ends in the sliding direction 12, the sliding edges taper relatively sharply to facilitate sliding on corresponding counter projections.

Also on the tube side 14, a number of mounting recesses 40 are formed on the upper edge of the mounting plate 3 with corresponding locking projections 43.

The pipe holder 15 is arranged centrally in the longitudinal direction 47 on the pipe side 14 of the mounting plate 3. This has in particular a receiving recess 16 for partially receiving a pipe to which the holder 1 according to the invention can be fastened.

The pipe holder 15 protrudes from the pipe side 14 of the mounting plate 3 and is manufactured as one piece with the mounting plate 3. Along the edges of the mounting plate 3 running in the longitudinal direction 47, support walls 49 protrude vertically from the pipe side 14, supporting the pipe holder 15 on both sides.

Figure 3 shows a section along the line III-III from Figure 1. Figures 2 and 3 show the essentially U-shaped cross-section of the pipe holder 15. This has two U-legs 22 and 23 and a U-web 24 connecting them. The U-web 24 is rounded and forms a support together with the upper end sections of the U-webs 22, 23.

Recess 16 for receiving a pipe (not shown).

The U-shaped web 24 is spaced apart from the mounting plate 3 on its side facing the tube side 14 thereof, and is visible from the housing side 45 according to Figure 1 through opening 35.

The U-legs 22 and 23 are essentially hollow and have an interior space 25. This is accessible from the housing side 45 through openings 26 and 27, respectively.

The U-leg 22 has an insertion opening 17 at its free end 28, which is essentially open towards the receiving recess 16. In addition to the insertion opening 17, a bearing projection 30 is arranged at the free end 28 within the U-leg 22, which points in the direction of the opening 26.

A bore 32 is formed in the U-leg 2 3 at its free end 29. In the interior 25 of the U-leg 23, a sleeve 33 with a hexagonal cross section (see Figure 1) is arranged concentrically to the bore 3 2. The sleeve 3 3 extends from the bore 32 to the opening 27 in the housing side 45. Adjacent to the bore 32, the sleeve 3 3 has two opposing retaining projections 34 which run in the direction of the bore 32 and are inclined towards one another.

Figure 4 shows a section along the line IV-IV from figure 1. It can be seen that the support walls 49 essentially have the shape of a right-angled triangle, with the hypotenuses running between the free end of the U-legs of the pipe holder and the pipe side 14 of the mounting plate 3, see also figures 2 and 3.

The locking hook 11 shown in the upper part of Figure 4 protrudes from the U-leg 22 according to Figure 3 perpendicularly opposite to the sliding direction 12 and has the locking lug 51 at its upper end. The locking hook 11 is arranged at a distance from the pipe side 14, with its locking lug 51 being arranged above an upper end of the sliding edge 10. In particular,

In Figure 4 it can be seen that the sliding edge 10 rises in a ramp-like manner in the sliding direction 12.

At the upper edge of the mounting plate 3, a mounting recess 40 with a locking projection 43 arranged in it is also visible.

Furthermore, a corrugation 52 is formed in the receiving recess 16, see also Figure 2, which serves as a friction-increasing means when attached to a pipe.

Figure 5 shows another embodiment of a holder 1. The holder 1, or mounting plate 3, is larger than in the embodiment according to Figure 1, with additional recesses 53 to 56 being formed in the mounting plate 3 in addition to the recesses 4, 5, 6 and 50. For the sake of simplicity, in the illustration according to Figure 5, for example, the push-on recesses 40 or structures arranged in the openings 26, 27 and 35 (see the description of Figures 1 to 3) have been omitted.

The recesses 4, 5 that are open towards the upper edge are designed without locking hooks. The corresponding sliding edges 10 are shown in dashed lines in the edge area of each recess.

In contrast to the embodiment according to Figure 1, the recess 50 is no longer open towards the upper edge, but is arranged in the mounting plate 3.

The other recesses 53 to 56 are each formed with a locking hook 11, which is constructed and arranged analogously to the embodiment according to Figures 1 to 4. Likewise, the sliding edges 10 rise in a ramp-like manner in the sliding direction 12, see Figure 4.

Figure 6 shows yet another embodiment of a holder 1 according to the invention with mounting plate 3.

As in Figures 1 and 5, the housing side 45 of the mounting plate 3 is visible. In the embodiment according to Figure 6, the mounting plate 3 can be attached to a corresponding tube in two mutually perpendicular orientations. Accordingly, a housing can be releasably attached to the holder 1 in two mutually perpendicular sliding directions 12.

In the first orientation running in the longitudinal direction 47 of the mounting plate 3, the latter is provided with two pipe receptacles 15 spaced apart from one another in the longitudinal direction. These are shown in Figure 6 by the corresponding openings 26, 27 and 35 and the structures visible in these openings. For a more detailed description of these structures, reference is made to the preceding figures.

In the transverse direction 46 of the mounting plate 3, a further alignment can be carried out using the pipe receptacles 15 marked by the openings 26, 27 and 35, see also the previous figures. For the sake of simplicity, in the embodiment according to Figure 6, corresponding recesses for inserting counter-projections according to Figure 11 have been omitted. These are constructed analogously to the previous figures.

Furthermore, corresponding mounting recesses 40 with locking projections 43 are shown for both fastening positions of the mounting plate 3.

Figures 7 and 8 show a section analogous to Figure 3.

A pipe 13 is arranged within each receiving recess 16, whereby the pipe according to Figure 7 has a larger diameter 48 than the pipe according to Figure 8. The pipe 13 according to Figure 7 lies flush against the rounding of the receiving recess 16, since its curvature corresponds in particular to the curvature of the U-shaped web 2 4. A half clamp 19 is arranged to fasten the bracket 1 to the pipe 13. This is

end 18 is inserted into the insertion opening 17, with the bearing projection 30 engaging in a corresponding bearing opening 31 of the bearing end 18. The half clamp 19 is then guided at least partially around the outer circumference of the pipe 13 and ends in a fastening end 21 that runs essentially in a straight line. This is assigned to the free end 29, see Figure 3, of the U-leg 23 and can be fastened to it by means of a screw and a nut held by the holding projections 34.

Due to the small diameter 48, an adapter 44 is also used in the pipe 13 according to Figure 8. This is located on the outer circumference of the pipe 13 with a corresponding pipe holder. On its side facing away from the pipe 13, the adapter 44 has a passage for a curved section of the half-clamp 19. In this way, the adapter and half-clamp 19 can be connected to one another before being attached to the bracket 1. The half-clamp 19 according to Figure 8 is attached in a similar way to Figure 7.

Figure 9 shows a sign carrier 41 which can be plugged onto the mounting recesses 40 according to Figures 1, 2 and 6 by means of locking legs 53 arranged on its underside and can be locked there with the locking projections 43 by means of corresponding counter-locking projections 54. It should be noted that, corresponding to the arrangement of the mounting recesses on both sides of the mounting plates 3 and the arrangement of the corresponding locking projections 43, the locking legs 53 according to Figure 9 are alternately directed towards one another with their counter-locking projections 54 so that they hold the mounting plate 3 between them.

The label carrier 41 has an interior space 55, see also Figure 10, into which a corresponding label can be inserted for more detailed identification, for example, of the housing for an electrical device attached to the mounting plate 3. Figure 10 corresponds to a view along the line X-X from Figure 9.

Figure 11 shows in principle a rear side of a housing 2 for an electrical device, such as a control device for an explosion-proof area, a light switch, a junction box or the like. Housing projections 7, 8 and 9 are arranged on the rear side, which enable a three-point fastening of the housing 2 to the mounting plate 3 according to Figure 1.

The upper housing projections 7, 8 have a substantially L-shaped cross-section. The L-leg protruding from the rear of the housing is inserted between the sliding edge 10 and the opposite edge 39, see in particular Figures 1 and 2, whereby the L-leg running essentially parallel to the rear of the housing engages behind the sliding edge 10. The engaging L-legs are designed to rise in a ramp-like manner opposite to the sliding direction 12, so that in conjunction with the ramp-shaped structure of the sliding edges 10, a self-locking effect is achieved when the housing 2 is pushed onto the mounting plate 3.

The lower housing projection 9 is essentially T-shaped or dovetail-shaped in cross section, with the two T-shaped crossbars each engaging behind a sliding edge 10 of the recess 6 according to Figure 1 or 2. The T-shaped crossbars also have a ramp-like material thickness that increases in the opposite direction to the sliding direction 12.
