    Installation box for electrical purposes.
    The invention relates to an installation box for electrical purposes for installation in a cavity wall or a noise barrier.
    Installation boxes of this type are widely known in the art. As a rule, they are cylindrical cans with a bottom. Such cans often have a bevel in the transition from the bottom to the side wall and breakouts or pierceable openings in this area in order to be able to insert connection lines into the can. In addition, such doses may also have fittings to couple together multiple cans into a unit can. Finally, such cans also often have integrated fasteners to secure them in a breakthrough on a wall or on a wall can.
    Such cans are also used in soundproof walls. Here, there is the problem that it often comes with the installation of such installation boxes in soundproofing walls to a weakening of sound insulation, since the noise protection formed by the soundproofing wall is weakened by the can. In particular, therefore, the opposite installation of two cans in the region of such a wall is not allowed. If the electrician brings in the usual installation boxes as usual in partitions with sound insulation function, there is a risk that a sound transmission is generated in the region of the installation. In order to avoid this weakening of the sound insulation it is usual in the
    Area of the installation site additionally provide rock wool clogs or casings with gypsum mortar. This arrangement and installation is very complicated and often not suitable for retrofitting.
    Based on this prior art, the present invention seeks to provide an installation box generic type that can be retrofitted in a simple manner, in which a weakening of the sound insulation, especially when installed in soundproof walls is avoided and in addition, if necessary an opposite installation in such a wall without disadvantages is possible.
    To solve this problem, the invention proposes that the installation box is designed as a soundproof box.
    The appropriate design of the installation box ensures that it does not weaken the sound insulation when installed in corresponding openings of noise barriers or the like, since the wall opening, which is required for installation of the installation box, is closed by the soundproof box, so that the soundproofing of this Job exists. As a result of such a design, a simple and quick installation is possible as well as a subsequent installation. An opposite installation, for example in the range of non-load-bearing walls is possible without the soundproofing is weakened.
    A preferred development is seen in that the installation box consists of a soft elastomer material.
    The fact that such an installation box made of soft elastomeric material, the soundproofing effect is achieved, yet the usual installation is possible and also the installation of switches and the like electrical elements in the installation box is possible.
    As a soft elastomer material, for example, thermoplastic polyethylene comes into consideration.
    A certain disadvantage of such an installation box made of soft elastomer material is that it may not be sufficiently rich in shape, so that the installation in the corresponding wall opening can be problematic or the use of appropriate installation equipment can be difficult in the installation box.
    For this reason, the invention proposes an alternative solution, which consists in that the installation box consists of a dimensionally stable plastic body, in particular of hard thermoplastic or thermosetting material and that the plastic body is equipped with soft, sound-absorbing material, in particular elastomeric material.
    As with conventional hollow wall boxes or the like, the installation box consists of a dimensionally stable plastic body of hard thermoplastic or thermosetting material. For example, it is usual
    Polypropylene or polyamide. This dimensionally stable plastic body is equipped with a soft and sound-insulating material, in particular elastomeric material. As a result, on the one hand, the dimensional stability of the installation box is ensured so that their installation in the corresponding wall opening can be done without complications and also the installation of appropriate equipment is facilitated in the installation box. On the other hand, the desired soundproofing effect is nevertheless achieved by the soft soundproofing material, so that such a box can be installed, for example, in corresponding perforations of a soundproofing wall without weakening the soundproofing.
    An embodiment of this can consist in that the dimensionally stable plastic body is lined on the inside with its walls and at the bottom with sound-absorbing material.
    Here, the dimensionally stable plastic body forms the outer skin of the installation box, while the sound-absorbing material forms the inner wall of the corresponding installation box, whereby the soundproofing effect is achieved.
    An alternative preferred embodiment, which can also be provided in addition to the aforementioned training, is seen in the fact that the dimensionally stable plastic body is covered on the outside at its walls and at the bottom with scha11dämmendem material.
    Again, a dimensionally stable plastic body is again provided, but this is covered on the outside with the sound-absorbing material. This ensures that the interior of the installation box, which is required for the installation of equipment and the like, is dimensionally stable and stable, so that corresponding devices can be well installed and fixed there. The sound-absorbing coating of the dimensionally stable plastic body forms an excellent sound insulation, wherein sound insulation is achieved by the sound-absorbing coating in particular in the area of the corresponding Wandungsdurchbruches, since any gap between the installation box and the surrounding hole reveal the hole in which the installation box is installed by the elastic sound absorbing material can be compensated.
    Such a solution is therefore preferred over other solutions.
    In any case, it is preferably provided that the layer thickness of the elastomer material is at least 2 mm.
    If the installation box itself is made of soft elastomeric material, the layer thickness is preferably at least 3 mm. If a combination is provided on a dimensionally stable plastic body with an elastomer coating, a minimum layer thickness of the elastomer material of 2 mm is sufficient. In the usual installation conditions and the usual tools of electricians is to ensure that the installation box has a total only such a maximum dimension that it can be installed in conventional holes, which are produced with the usual tools.
    The interior of the installation box is in turn intended for the installation of standardized equipment, so that the interior of the installation box can not be excessively restricted. Taking these parameters into consideration, the wall thickness of the dimensionally stable plastic body is 0.5 to 1 mm, and for the elastomer layer thickness is approximately 2 mm.
    In addition, it is preferably provided that the elastomer material has a Shore A hardness of 20 to 100.
    A particularly preferred development is seen in that the bottom and / or the wall of the installation box relative to the layer of Elastomerem material to the outside of the installation box has projecting zones of hard plastic.
    According to this embodiment, the bottom and / or the wall of the installation box to the outside of the installation box protruding zones of hard plastic, which protrude from the outside of the installation box forming layer of elastomeric material. At the bottom of the installation box, these zones provide guidance in the handling of the installation box in the manufacture and packaging, since sliding surfaces are formed by these zones of hard plastic, so that the installation box can be mechanically or manually deported with its bottom on a corresponding lower surface, without the sound-insulating layer of elastomer material hinders this displacement movement. Also provided in the area of the wall projecting zones of hard plastic form a handling advantage in the manufacture and assembly, since it is possible by this arrangement to use the installation boxes for the purpose of mounting in a tool, such as a mounting sleeve, without the elastomer layer a Reibungshemmnis forms, because not these, but the protruding zones on the wall of the sleeve or the like slide along.
    The invention further provides an alternative solution, which consists in that the installation box is designed as a double-walled hollow body.
    In this case, it is provided, in particular because of the better sound insulation, that an air gap is formed between the double walls in the wall area and in the floor area of the installation box.
    If such an air gap is insufficient, it can be provided that the air gap is partially or completely filled with sound insulation material.
    In addition, it is preferably provided that the hollow body consists of hard thermoplastic or thermosetting material.
    The hollow body can be made as a double-walled hollow body of elastomeric material or, what is preferred, of dimensionally stable plastic material. The air gap formed between the double walls serves as a soundproofing element, wherein particularly when the air gap is partially or completely filled with sound insulation material, such as elastomeric plastic, a particularly excellent soundproofing is achieved.
    In addition, it is preferably provided that the installation box is designed as a flush box.
    Alternatively, it is preferably provided that the installation box is designed as a hollow wall box.
    The shape of the installation box therefore corresponds either to a conventional flush-mounted box or a conventional cavity wall box. All installation elements as well
    Cable entry options and
    Mounting options that are common in flush-mounted boxes or hollow wall boxes, can also be integrated into the installation box according to the invention.
    In particular, it is provided that the installation box has a flange edge on the outlet side.
    This makes it possible, as is common in hollow wall boxes, for example, to insert the installation box into a perforation of a wall, with the flange edge being then supported on the outside of the perforation in the desired mounting position. The flange edge thus forms a Einschubtiefenbegrenzung.
    In addition, it is preferably provided that the installation box on the outer jacket at least one
    Receiving channel for a screw, whose
    Head abutment formed on a mouth side of the installation box, this is the cross-shaft with the shaft of the screw supportable, wherein near the bottom of the can bottom end of the receiving channel
    Tab bearing for a threaded with the
    Screw shaft connected pivotable retaining tab is formed, in which the retaining tab can be pivoted into a preassembly position and from which the retaining tab in a position of use is swung out, in which it projects laterally from the installation box, the tab bearing a support surface made of hard plastic as part of the hard plastic Plastic body and / or the abutment for the head of the screw is formed as part of the existing plastic hard plastic body, wherein the support surface and / or the abutment directly, without interposition of sound-insulating material on the located in the Vormontagelage retaining tab and / or the head the adjusting screw is applied.
    The arrangement of corresponding actuating and Halteelmente is known in the art, especially in so-called hollow wall boxes.
    The particular feature of the invention is that preferably both the support surface of the tab bearing and the abutment for the head of the screw made of hard plastic are formed as part of the hard plastic plastic body, wherein the plastic body is otherwise preferably wrapped with sound-absorbing material, in particular soft elastic elastomer ,
    Only at the specified points the hard plastic occurs, so that stable support surfaces are formed for the pivotable retaining tab and for the head of the screw, so that the mechanical function of these elements are ensured despite the sound-insulating design of the installation box. Depending on the application, it is not necessary to manufacture both the support surface and the abutment made of hard plastic, but depending on the application, an alternative training only the support surface or only the abutment made of hard plastic can be done.
    A preferred embodiment of a soundproof box according to the invention is shown in the drawing and described in more detail below.
    It shows:
    Figure 1 seen a soundproof box from obliquely above;
    Figure 2 also seen from obliquely below;
    Figure 3 shows the can in side view;
    Figure 4 shows the box in section A-A of
    Figure 3 seen;
    Figure 5 shows the detail V of Figure 4 in an enlarged view;
    Figure 6 seen the can from below;
    Figure 7 shows the can in section E-E of
    Figure 6 seen;
    8 shows the detail VIII of Figure 7 in an enlarged view.
    In the drawing, an installation box (1) for electrical purposes for installation in a cavity wall or a soundproof wall is shown. These
    Installation box 1 is designed as a soundproof box. For this purpose, the installation box 1 consists of a dimensionally stable plastic body 2, preferably made of hard thermoplastic material with an equipment with soft sound insulating material 3, preferably an elastomeric material.
    In the exemplary embodiment, the dimensionally stable plastic body 2 is externally covered on its peripheral wall and on the ground with sound-absorbing material 3, as is particularly clear from the sectional views of Figure 4 and 7 can be seen. The installation box 1 can be advantageously produced in a so-called 2-component injection molding.
    The layer thickness of the elastomer material 3 is at least 2 mm, while the wall thickness of the dimensionally stable plastic fkörpers 2 may be about 0.5 to 1 mm.
    The elastomeric material preferably has a Shore hardness of A 20 to 100.
    The bottom of the installation box 1 has over the layer of elastomeric material 3 to the outside of the installation box 1 projecting zones 4 made of hard plastic. Likewise, the wall of the installation box 1 with respect to the layer of elastomeric material 3 radially to the outside of the installation box projecting zones 5 made of hard plastic. In the exemplary embodiments, the zones 4, 5 are formed by webs. In the embodiment, the zones 4 and 5 are made of hard plastic in one piece to the ground or the
    Formed wall of the dimensionally stable plastic body 2 and reach through the externally applied sound-absorbing material 3 and protrude with respect to this outward. Such training is advantageous in the usual handling of the installation box 1, for example, when the box is to be moved on a smooth surface, as is sometimes necessary in manufacturing, since then form the zones 4 quasi sliding surfaces, so that the installation box 1 according to easily a surface is displaceable. Similarly, the zones 5 are sliding aids when the can 1 is to be inserted into a mounting sleeve or the like in order to make further manipulations, because thus the elastomeric material 3 does not come into contact with the wall of the mounting sleeve.
    In the exemplary embodiment, the installation box 1 is designed as a conventional hollow wall box, so has their usual technical features. In particular, the installation box 1 at the mouth side has a circumferential flange edge 6, which is part of the dimensionally stable plastic body 2. Furthermore, the installation box 1 on the outer jacket opposite two receiving 7 for adjusting screws 8, the head in a mouth side of the installation box 1 formed abutment 9, this with the shank of the screw 8 by cross-supporting. Near the bottom end of the receiving channel 7, a tab bearing 10 is formed for a threadedly connected to the screw shank of the adjusting screw 8 pivotable retaining tab 11, in which the retaining tab 11 in a Vormontagelage according to Figure 2 can be pivoted and from which the retaining tab 11 is pivoted into a position of use so that it protrudes laterally radially from the can. The tab bearing 10 forms a support surface made of hard plastic as part of the existing plastic hard plastic body 2. Likewise, the abutment 9 is formed for the head of the adjusting screw 8 made of hard plastic as part of the hard plastic plastic body 2. Thus, the support surface 10 and the abutment 9 is directly and without an intermediate layer of sound insulating material on the located in the Vormontagelage retaining lug 11 and the head of the screw 8, so that with respect to the arrangement and adjustment of these elements, the dimensional stability of the dimensionally stable plastic body 2 is crucial and not the less dimensionally stable mass of thermoplastic material. 3
    The invention provides an installation box 1 available, which is particularly suitable and intended for installation in soundproof walls and which improves the sound insulation, or avoids weakening of the sound insulation of a corresponding sound insulation largely.
    The invention is not limited to the embodiments, but in the context of the disclosure often variable.
    All new, disclosed in the description and / or drawing single and combination features are considered essential to the invention.
