    专利说明:

    The invention relates to the field of building installation technology, and in particular to an installation element for hollow walls and a spacer element according to the preamble of the corresponding independent claims.
    Installation elements for hollow walls, including hollow wall boxes, are used for example in the form of Elektroninstallationsdosen for electrical installations on lightweight walls. This can e.g. on walls plastered with gypsum fiber boards. It may also be that the same installation boxes are used in panel or apparatus construction. Gypsum fiber boards or similar boards of other building materials such as wood or wood fiber boards each have a thickness of, for example, 8 mm and more. In contrast, panels in panel or apparatus construction have a thickness in the range of, for example, 1 mm to 5 mm.
    There are various installation boxes for hollow walls. Some of them are attached with staples and claw tiles. Since the claws can be rotated for mounting behind the box and then unscrewed with a rotary movement of the screw, the lead of the screw must be relatively long in such installation boxes.
    The disadvantage of this installation boxes is that due to the relatively long guidance of the screw, the claw can not be screwed close to the wall and therefore the installation boxes are not suitable for thin walls, respectively sheets. Another possibility is that the claws - are made thicker - according to the length of the guide of the screw. However, this has the disadvantage that there are restrictions on the maximum permissible thickness of the lightweight board.
    It is therefore an object of the invention to provide an installation box or generally an installation element of the type mentioned, which overcomes the disadvantages mentioned above.
    Another possible object is to provide an installation box, which can be used for both (lightweight) plates with thicknesses of 8 mm to 30 mm and for plates or sheets with thicknesses from a thickness of 0.8 mm.
    This object is achieved by an installation element having the features of patent claim 1.
    The installation element is therefore provided for mounting on a plate. It has at least one stop and at least one clamping element, which is movable by means of a screw in the direction of the at least one stop. In this case, the installation element further comprises at least one spacer element, which is intended to be attached to at least one clamping element and thereby to reduce a gap between the at least one clamping element and the at least one stop.
    In other words, therefore, if the spacer element is attached to the clamping element, the gap between the spacer element and stop smaller than the gap between the clamping element (without spacer element) and stop.
    When mounting the installation element to a plate which falls below a certain minimum thickness, for example, 8 mm, a spacer element is attached to a clamping element in each case. For thicker plates, for example, up to 30 mm thick or more, the installation element can be mounted without using the spacer elements. The spacer element can also be referred to as installation auxiliary element.
    In one embodiment, the installation element is a box for electron installations and in particular a cavity wall box. It may, for example, form a junction box and / or a lamp box.
    In one embodiment, the spacer element after attachment to the clamping element forms a snap connection with the clamping element.
    In one embodiment, the spacer element after attachment to the clamping element forms a frictional connection with the clamping element.
    In one embodiment, the spacer element is attachable to the clamping element.
    In one embodiment, the spacer element has at least one slip-on, and is and can be plugged with this on the clamping element.
    In one embodiment, the shape of the plug-in opening corresponds to the shape of the clamping element and allows plugging of the spacer element in only one orientation with respect to the clamping element. For an anti-rotation of the spacer element is realized. This can be advantageous if exactly one plug-in opening is present and errors when plugging are made impossible.
    In one embodiment, the spacer element in the mounted state on one of an associated stop facing clamping surface on one or more pointed projections. These can drill into the respective plate and thus prevent a displacement of the installation element.
    A spacer element for use with an installation element is intended to be attached to at least one clamping element. One or more such spacer elements may be present as individual products, or as a kit in combination with an installation element.
    Further preferred embodiments will become apparent from the dependent claims.
    In the following, the subject invention based on preferred embodiments, which are illustrated in the accompanying drawings, explained in more detail. Each show schematically:<Tb> FIG. 1 <SEP> an installation element without spacer element;<Tb> FIG. 2 <SEP> an installation element with spacers;<Tb> FIG. 3 <SEP> an installation element in the mounted state and without spacers on a relatively thick lightweight board;<Tb> FIG. 4 <SEP> an installation element in the assembled state and with spacer elements on a relatively thin sheet metal plate;<Tb> FIG. 5 <SEP> an installation element, for comparison with clamping element and distance element at the maximum distance from the stop;<Tb> FIG. 6 <SEP> an installation element, for comparison with clamping element and spacer at the minimum distance from the stop; and<Tb> FIG. 7-9 <SEP> Views of various embodiments of spacer elements with a view against their Aufstecköffnungen.Grundungsgemäß the same or the same parts are provided with the same reference numerals in the figures.
    Fig. 1 shows a hollow wall box 10 as an installation element without spacer element, and Fig. 2 the same cavity wall box 10 with spacers 4. The spacer elements 4 are attached to clamping elements 1. The clamping elements 1 are movable with screws 2 in a direction against stops 8. In this case, a between clamping element 1 (respectively spacer element 4, which is mounted on a clamping element 1 is mounted) and stop plate 8 are clamped and thus the hollow wall box 10 are fixed relative to the plate. Projections 9 of the clamping element 1 or projections 42 on a clamping surface 41 of the spacer elements 4 (see FIGS. 7 to 9) can drill into the respective plate and thus prevent a displacement of the hollow-wall box 10. In the following sectional drawings, in addition to the elements already mentioned, screw guides 3 for guiding the screws 2 can still be seen, as well as plates with different thicknesses.
    The installation element 10 is typically made of plastic in an injection molding process. The installation element 10 may, for example, form an electrical junction box and / or a lamp box for electrical installations.
    Screws 2 and clamping elements 1 are typically made of metal. The spacers 4 can be made of a hard plastic, also by injection molding. They can also be made of rubber or a soft plastic.
    For mounting the hollow wall box 10 without the spacer elements 4, the hollow wall box 10 can be pushed through a hole in a plate. The clamping elements 1 are rotated behind the contour of the hollow wall box 10, and can thus be passed through the hole. When turning the screws 2, first the clamping elements 1 rotate away from the can, into the position shown in Fig. 1, and are then pulled on further rotation of the screw 2 in the direction against the respective stops 8 relative to the plate.
    Fig. 3 shows an installation element 10 in the assembled state and without spacers on a relatively thick lightweight panel 20. The lightweight panel 20 is clamped between the clamping elements 1 and the stops 8.
    Fig. 4 shows an installation element 10 in the assembled state and with spacers 4, which are plugged onto the clamping elements 1, on a relatively thin metal plate 30. The metal plate 30 is clamped between the spacer elements 4 and the stops 8.
    Fig. 5 shows an installation element 10, for comparison with clamping element 1 and spacer element 4 at the maximum distance from the stop 8. The maximum thickness of a plate on which the installation element 10 is mounted, corresponds to the maximum distance between the stop 8 and the Clamping element 1 without spacer element. 4
    Fig. 6 shows an installation element 10, for comparison with clamping element 1 and spacer element 4 at the minimum distance from the stop 8. The minimum thickness of a plate on which the installation element 10 is mounted, corresponds to the minimum distance between the stop 8 and the mounted on the clamping element 1 spacer element. 4
    Fig. 7 shows a spacer element 4 with three Aufstecköffhungen 5. Thus, the spacer element 4 can be inserted in different positions on the clamping element 1. By way of example, the position of a spring element 6 of one of the plug-in openings 5 is shown. The spring element 6 may be part of a snap connection, by means of which the spacer element 4 engages after attaching the mounting opening 5 on the clamping element 1. The spring element 6 may also be part of a frictional connection, for example, by the spacer element 4 is made of a soft plastic or rubber and when plugging the spacer element 4 is slightly deformed and stretched.
    Fig. 8 shows a spacer element 4 with a mounting opening 5 with a rotation. The mounting opening 5 is formed corresponding to the shape of the clamping element 1. Because of the protruding projections 9 of the clamping element l, the spacer element 4 can be inserted only in one orientation on the clamping element 1. As shown in FIG. 9, an anti-twist device can also be present at a plurality of plug-on openings 5 of a spacer element 4.
    In FIGS. 7 to 9, projections 42 are schematically shown on the clamping surface 41, which have the same function of the projections 9 of the clamping element 1, ie to drill into the respective plate and thus prevent a displacement of the installation element 10.
