Definitions

• the subject of the present application is a new type of holder for ceiling and wall loudspeakers and built-in lamps.
• the holding frame which is usually a few centimeters wider than the recess provided for the loudspeaker or the lamp, compensates for irregularities in this recess and possible size variations of the loudspeakers and is either screwed directly against the wall or ceiling or by means of bendable metal sheets , which are pressed against the back of the holding plate encompassing the loudspeaker recess.
• the screw holes or screw heads that are visible afterwards prove to be of little aesthetic advantage.
• the assembly is very complex since the fastening elements have to be bent through the holding frame and can only be inserted after the finished assembly of the loudspeakers and the cover plate can be put on.
• speakers attached in this way can only be detached from their attachments with difficulty without destroying the holding device.
• spring elements can be placed on the back of the holding frame without problems, which are pushed through the recess of a corresponding holding plate and then by means of a trigger element which pierces the holding frame or the lamp or loudspeaker housing and the cover plate, are triggered, whereby the spring rests against the back of the holding plate (in the following, for the sake of simplicity, reference is only made to “loudspeakers”, whereby the analog application to "lamps” is also to be included).
• the ceiling or wall cladding which consists, for example, of a wooden or metal panel or a plasterboard or insulation board, or a special plate placed on the wall or ceiling, serves as the holding plate.
• the spring elements which are used according to the invention are sufficiently strong to hold the holding frame with the loudspeaker firmly in position, on the other hand so resilient that the entire holding frame can be pulled out of the holder against the spring force when this occurs is desired. The entire unit is then put back into a ready-to-install state by simply re-engaging the release element.
• a spiral spring is preferably used, which is mounted about an axis in the lower part of the shock absorber and is preferably still covered by a spring plate which is movable about the same axis, so that when the spring hits the holding plate, the spring pressure is greater than one ⁇ Outer area is distributed.
• the holding plate is not made of a solid material such as wood, but of plasterboard or the like, which is often used in the construction industry for wall and ceiling lamination.
• a pin which projects through the cover plate to the outside and is guided in a guide hole of the holding frame and the top of the spring strut, serves as the trigger element.
• An eyelet which connects this release pin and the spring, prevents the spring from being able to move away from the vertical position due to its spring force in the installed position. After assembly, the pin is pulled out of the eyelet and the spring is thereby released so that it folds over and presses the frame against the holding plate due to its spring force.
• the pin is pulled downward by the cover plate and is usually thrown away or moved, so that a new pin and usually also a new retaining eyelet are required when the spring element is re-installed in the mounting position.
• the retaining pin is bent in a U-shape in the region of the upper plate of the suspension strut and leads back again through a second retaining opening. The eyelet is now only attached to the short return and preferably passed through a hole in the spring cover plate for further attachment.
• the loudspeaker, holding frame and cover plate Since, according to the invention, it is no longer necessary to carry out a rear-side attachment through the holding device, it is possible to mount the loudspeaker, holding frame and cover plate at the factory, which considerably simplifies and shortens the final assembly. This also results in the further advantageous possibility of integrally forming the holding frame together with the loudspeaker housing from the outset, and thus significantly reducing the costs compared to a two-part design. Since the cover plate is also installed at the factory in this type of installation, it can be glued or crimped, which has a considerable advantage over the previously required press fastenings during final assembly.
• the attached drawing 1 shows a fastening element according to the invention, the loudspeaker 1 being integrally connected to the holding frame 2, in which the cover plate 3 is inserted.
• the strut 4 has an axis 5, around which the spring 6 and a spring plate 7 are rotatably mounted, which are bent against the holding plate 8 in the state shown. Furthermore, the mounting eye 9 on the spring element is indicated, which is locked against the trigger element 10 in the installed state
• FIG. 2 shows a detailed drawing of this spring strut 4, the spring being locked in the assembly position.
• Figure 3 shows the arrangement of the strut 4 from the front, the axis 5 and spring 6 are covered by the spring plate 7.
• FIG. 4 shows another embodiment of the fastening element in perspective reproduction, in which the spring strut 4 is designed as a box which is open on one side and carries a tab 11 bent outwards on the rear wall 4 '.
• the two side walls 4 "in turn hold the axis 5 with the spring 6 and the spring plate 7.
• a perforation 12 is provided, into which, in the mounting position, the part of the trigger element 10 bent downwards (in the present case a U-shaped wire) with a shortened leg), which is fixed by a guide hole 13 in the tab 11 and an opening in the holding element 2 (not shown).
• FIG. 5 shows a further embodiment of the fastening element, in which the spring strut 4 is U-shaped and one leg 4 ′ ′′ carries the bent tab 11, so that the rear wall 4 ′ is omitted compared to FIG. 4. All other elements correspond to FIG and are labeled in the same way.
