Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a means for mounting a support air passage, in particular for securing air outlets in an assembly housing by means of fasteners.

Particularly at anchorage points covered, air outlets and similar air inlet devices are secured on holders which are housed in a housing. The brackets are usually fastened by means of screws which are screwed into a threaded hole in a U-profile section. The known bracket constructions are costly and difficult to produce and have the disadvantage that they are a non-negligible source of noise. The brackets are usually fixed in the assembly housing by spot welding. This technology results in the development of flue gases and vapors, which are harmful to health and polluting the environment, and require an excessive amount of energy. In the area of spot welding, at least in industrial conditions, extraction equipment must also be operated, which also results in additional energy consumption and requires a considerable amount of dirt to be discharged into the open air. Not to be neglected is the energy loss resulting from the heating of fresh air in the area of spot welding.

It is an object of the present invention to provide a solution which eliminates the aforementioned shortcomings of conventional constructions, does not require welding, and provides a versatile fixing possibility for air-passage devices and air-outlets.

To accomplish this object, there is provided a bracket having a tubular bracket having a mounting member for mounting a fastening member, such as a screw, optionally with a threaded bore. The tubular support member may preferably have an oval cross-section, but may of course have a different shape.

The tubular support is preferably formed of aluminum or plastic.

In a preferred embodiment of the bracket according to the invention, the tubular bracket has open ends which are closed by plugs. The plugs can be inserted through the side walls of the housing into the open ends of the tubular bracket. In this case, the plugs closing the open ends of the tubular bracket also secure the bracket to the fixture housing. The plugs are preferably plastic plugs which, through the openings in the sidewalls of the housing, can be inserted very easily into the pipe ends.

Preferably, the retaining member may be formed as a sleeve having a female thread for retaining the retaining member.

The sleeve is further provided with an annular flange, optionally resting on the tubular support, and defining the implant depth of the sleeve.

In a further preferred embodiment of the bracket according to the invention, the tubular bracket is guided through a bore in a socket. The socket is provided with a projection groove for receiving the fastener next to the bore.

The pick-up bore is preferably formed as a through-hole, the openings of which are provided with an outwardly expanding funnel. With this design, the coupling of the spindle thread and the female thread, where appropriate, is greatly facilitated.

Thus, there are basically two ways to fix the fasteners. According to one embodiment, a socket with a female thread is inserted into the holder, into which the fastening element, optionally a screw, connected to the air-transfer device can be easily folded. Threaded cap • ·

of course, any known soluble linkage may be used instead of a bond.

Alternatively, the tubular bracket is received by a socket, optionally a block having a corresponding bore, and in this socket a device for receiving the fastener, such as a threaded bore, is provided adjacent the tubular bracket. The advantage of this latter solution is that the position of the tubular holding member along the socket can be varied so that problems of fitting air outlets can be eliminated if necessary.

A further advantage of the attachment by means of the socket is that the attachment can be carried out on either side of the tubular support.

The invention will now be described with reference to the drawing. In the drawing:

Fig. 1 shows an example of a bracket according to the invention. an outline of an embodiment thereof is shown in a side view and in a cross-section according to I-I;

Figure 2 is a side view of a further exemplary embodiment of the bracket of the invention and a cross-sectional view taken in accordance with II-II.

As can be seen from the figures, the air outlet assembly housing 1 has side walls 2 and 3, between which brackets 4 and 4.1 are arranged. The holder 4 of Fig. 1 is an oval tubular member, for example of aluminum or plastic, the open ends of which are closed by plugs 5 through the openings of the side walls 2 and 3. Thus, by means of the plugs 5, the bracket 4 - and likewise the bracket 4.1 of Figure 2 - is fastened between the side walls 2 and 3 of the housing 1. Mounting is extremely easy with the 4 and 4.1 brackets

the fitting only needs to be brought into position and the plugs 5 must be pushed through the openings in the side walls 2 and 3 into the open pipe ends.

1, a sleeve 6 is provided in the bracket 4 having a female thread 9. The female thread 9 receives the spindle thread 8 of the screw 7 implementing the fastener. As mentioned above, other soluble joints may be used instead of the threaded connection.

The sleeve 6 further has an annular rim 10 which defines the depth of insertion of the sleeve 6 into the bracket 4.

It will be appreciated that the screw 7, or other suitable fastener, may be used to secure any air passage device to the bracket 4.

In the exemplary embodiment shown in Fig. 2, the holder 4.1 is embedded in an oval bore 12 of the socket 11, optionally slidably. In addition to the oval bore 12, a socket 13 is formed in the bottom socket with a female thread 14 for receiving the spindle thread 8 of the screw 7. In this example, the pick-up hole 13 is a through-hole, each of which has an outwardly extending funnel 15 or 16 for ease of screwing.

The advantageous effect of the variant of Fig. 2 is that the all socket can be displaced along the bracket 4.1 so that the exact fitting of the air outlets can be easily solved and any fitting problems can be eliminated. Another convenient possibility is that the mounting hole 13 may be located on either side of the bracket 4.1.
