Description

[0001] The invention relates to an electrical installation device, in particular a surface-mounted or flush-mounted device, for building installation technology according to the preamble of claim 1.

[0002] Such electrical installation devices are typically equipped with a device insert and a mounting plate, a central cover plate, and a writable cover frame, and are designed for use with a specific installation device program, specifically a switch and socket program, as well as for combinations with other devices from that same program. These electrical installation devices can be, for example, switches, push buttons, dimmers, motion detectors, sockets, etc.

[0003] Since the initial installation and labeling of the devices do not necessarily take place at the same time and are often carried out by different people, it is necessary to remove the already installed cover frames of the installation devices, which involves increased assembly effort, especially during the initial setup of the installation device or during renovation work.

[0004] Against this background, DE 102 27 562 B4 discloses a cover frame for an electrical installation device which has a label carrier designed as a label module which has locking elements by which the label module locks to a cover frame.

[0005] From DE 103 18 329 A1, an installation device is known which is equipped with a walk-on sign holder. The sign holder is pushed through an open recess in the frame from the front. On its back are hook-and-loop fasteners that interact with corresponding hook-and-loop fasteners of a support element. The sign holder is covered with a transparent protective strip that abuts against stop elements of the cover and forms a flush finish to the front surfaces.

[0006] The electrical installation device known from EP 2 393175 A1 is equipped with a labeling carrier designed for placement between a flush-mounted device insert and a viewing window of a cover frame of the installation device. The labeling carrier is attached to the cover frame by means of additional spring elements and is provided with positioning lugs for correct alignment on the device insert.

[0007] From DE 10 2013 100 909 B3, another installation device is known, featuring a label holder for receiving a label, which is attached to the frame of the installation device by means of a multitude of individual parts, such as sliding pieces, retaining elements, and adhesive carriers. The label holder projects into the viewing window opening of the cover frame, which can be closed with a viewing window element, and has recesses for securing it to the support, which interact with a sliding piece. The sliding piece is equipped with a complex internal toothing. The internal toothing of the sliding piece engages with a retaining element, allowing the sliding piece to be secured to the support via the retaining element.

[0008] DE 10 2010 016 648 B4 discloses an electrical flush-mounted installation device with a mounting bracket for fixing at the installation site, to which a cover frame with a viewing window can be attached. A bracket is provided for holding a label, and the label is attached to the bracket by means of a spring clip.

[0009] The invention is based on the objective of providing an installation device comprising a device insert with a support plate, a central disc, a cover frame and a labeling element, wherein the labeling can be applied in a simple manner even afterwards, without having to remove the already installed cover frame and, in particular, reducing the assembly effort when labeling the installation device.

[0010] The labeling element, also referred to as a label or writable strip, should remain on the installed flush-mounted insert after initial installation, even if the frame is removed, for example during renovations. The rationale behind this requirement is to ensure the correct assignment of the flush-mounted inserts of the installation devices to the sub-distribution board or main distribution board after renovations or repairs.

[0011] The problem is solved according to the invention by an electrical installation device, in particular a flush-mounted device, for building installation technology with device insert, a central disc and cover frame to be applied thereon, and a label which is provided with information for a user or installer.

[0012] The problem is solved according to the invention with the features specified in claim 1.

[0013] Advantageous embodiments and expedient further developments of the invention are specified in the dependent claims.

[0014] The electrical installation device according to the invention is equipped with a device insert with a support plate, in particular a flush-mounted insert, and a central disc located thereon, a cover frame with at least one viewing window opening that can be closed with a viewing window and at least one label holder for receiving a label.

[0015] The label holder is provided on its side facing the mounting plate with at least one adhesive tape, also known as double-sided adhesive tape, having a first and a second adhesive side. According to the invention, the label holder is inserted or snapped into the viewing window opening via the back of the cover frame, preferably in a pre-locking position, with a portion of the label holder initially projecting partially out of the viewing window opening of the frame. This portion is provided with a recess, for example in the form of a groove, which receives the label or into which the label can be inserted.

[0016] The cover frame, together with the label holder and the first adhesive side of the tape applied to it, forms a pre-assembled unit. This pre-assembled unit can be fixed to the mounting plate of the device insert using the second adhesive side of the tape. The label holder, fitted with the label, can be pressed down via guide elements, such as ribs, located within the frame, so that the label holder is positioned deep enough in the frame that, after the viewing window is placed or snapped into place on the cover frame, it sits flush.

[0017] The advantages achievable with the invention lie particularly in the fact that the label holder is mounted over the frame in such a way that the label can be easily inserted into the holder. The pre-assembled unit, with the double-sided adhesive tape applied to the label holder, enables secure positioning and attachment to the mounting plate of the device insert. The cover frame can be designed as a single, double, or multiple cover frame and accordingly has one, two, or more viewing windows for receiving the label holders.

[0018] According to the invention, the double-sided adhesive tape is provided on the second adhesive side, i.e., the side facing away from the sign holder, with a removable protective film that extends beyond the adhesive surface. The protective film protrudes beyond the frame. After removing the protective film, the adhesive layer is advantageously exposed on the second adhesive side when the sign holder is mounted. After the frame is mounted to the wall, the protective film can be pulled out of the frame at one or both of its protruding ends, thus exposing the second adhesive side of the tape.

[0019] By pressing down the label holder, it is then attached to the mounting plate of the device insert using the adhesive tape.

[0020] Since the label holder is equipped with locking elements according to the invention, which interact with guide elements located in the frame, the label holder is inserted into the frame after the label has been placed in such a way that the transparent viewing window attached or clipped onto it is flush with the surface of the cover frame. This significantly reduces the installation effort for the electrician. Furthermore, the mounting and subsequent labeling of the frames can be carried out separately.

[0021] It proves particularly advantageous that, for example in the case of renovation, the label holder glued to the tag plate with the corresponding label on the support plate remains in the position specified by the frame, even if the cover frame is removed.

[0022] The label holder is provided on its back with at least one adhesive tape having a first and a second adhesive side, wherein the label holder is inserted into the viewing window opening via the back of the cover frame.

[0023] Initially, a portion of the label holder protrudes partially from the viewing window opening of the frame. This portion is provided with a recess, preferably a groove, designed to hold the label. The label holder is equipped with locking elements that secure it behind an edge of the frame downwards and, via stops arranged on the frame, upwards.

[0024] The cover frame is installed according to the following steps.

[0025] In the first assembly step, the label holder, pre-assembled as a unit, is inserted into the viewing window of the cover frame via the back of the frame using double-sided adhesive tape. Initially, a portion of the label holder protrudes partially from the frame's viewing window. The groove for the label is integrated into this section. After the label is inserted into the groove of the accessible part of the label holder in the second step, the protective films protruding between the wall and the cover frame are removed. In the final assembly step, the label holder is pressed down towards the wall or into the cover frame, thus securing it to the mounting plate of the device insert with the adhesive tape.The final assembly step involves snapping the viewing window onto the cover frame, thus ensuring a flush finish on the frame.

[0026] The invention, further embodiments and advantages will be described in more detail with reference to the exemplary embodiments shown in the following drawings.

[0027] They show: Fig. 1 A top view of a cover frame of an electrical installation device with two pre-mounted label holders 6, 7 in an exemplary embodiment, Fig. 2 an exemplary cover frame of an installation device in pre-assembled exploded view, Fig. 3 the exemplary cover frame of the installation device as a pre-assembled unit, Fig. 4.

[0028] In Fig. Figure 1 shows a top view of a double cover frame 1, or the front of an exemplary flush-mounted electrical installation device, which has mounting options for two flush-mounted device inserts. A central cover plate is attached to each device insert according to the device's function. The double cover frame 1 completes the electrical installation device under consideration.

[0029] The exemplary cover frame 1 shown here is equipped with two pre-mounted label holders 6, 7. The two label holders 6, 7 have grooves or openings for receiving a writable strip or a label, respectively. At the factory, a label holder 6, 7 is inserted into each of the openings in the frame from the rear of the frame, with the holders 6, 7 protruding slightly from the viewing window openings in the frame 1.

[0030] The label holders 6 and 7 are each factory-fitted with double-sided adhesive tape on their underside. This double-sided adhesive tape, also known as the label carrier, allows the label holders 6 and 7, with the inserted label, to remain in place on the mounting plate of the flush-mounted insert even after the cover frame 1 has been removed.

[0031] The double-sided adhesive tape 10, 11 is provided on the side facing away from the sign holder 6, 7 with a removable protective film 4, 5 that extends beyond the adhesive surface. After mounting the frame 1, the protective film 4, 5 protrudes between the wall and the frame 1 and is removed after the frame 1 is mounted on the device insert or on the wall. To do this, after mounting the frame 1, the protective film 4, 5 can be pulled out of the frame 1 at one or both of its protruding ends, so that the second adhesive side of the adhesive tape 10, 11 is exposed.

[0032] A particular advantage is that the viewing window openings in the frame are aligned with the height of the label holders in such a way that wallpaper or plaster compensation can take place when the viewing window is inserted.

[0033] Fig. Figure 2 shows an exemplary cover frame 1 of an installation device and the components which are joined together with the cover frame 1 in the pre-assembled state, in exploded view.

[0034] The pre-assembled double frame 1 shown here has two viewing window openings 24 and corresponding label holders 6, 7 with applied double-sided adhesive tape 10, 11 and protective film 4, 5. The double-sided adhesive tape 10, 11 serves to fix the label holder 6, 7 to the mounting plate of the device insert.

[0035] The viewing window openings 24 have guide elements designed as webs 23 which prevent the lettering plate holders 6, 7 in the frame 1 from tilting when pressed down.

[0036] The label holders 6, 7 have recesses 22, preferably in the form of grooves, each of which receives a label 8. Each label holder 6, 7 is covered with a viewing window 2, 3 made of transparent plastic.

[0037] Fig. Figure 3 shows the exemplary double cover frame 1 of the installation device as a pre-assembled unit, into which the labeling plates 8 can be inserted into the respective labeling plate holders 6, 7 which partially protrude from the frame 1, and the double-sided adhesive tapes 10, 11 which are not visible here are applied with their adhesive surfaces on the back of the labeling plate holders 6, 7.

[0038] The area of ​​the respective label holder 6, 7 that protrudes from the frame 1 is designed in such a way that the corresponding label 8 can be inserted into the recess 22 designed as a groove in the respective label holder 6, 7 without having to remove the label holders 6, 7 from the frame 1, since the groove 22 is located outside the frame 1 in the pre-assembled state and is therefore freely accessible.

[0039] Fig. Figure 4 shows a first sectional view and a detail view A of the exemplary cover frame 1 placed on the wall 9 with the label holder 6 inserted into the viewing window opening 24 (not visible here) via the back of the frame, in which the label 8 is inserted, and the double-sided adhesive tape 10 and the protective film 4.

[0040] The illustrated label holder 6 is designed such that it can be pressed downwards, i.e. towards the frame 1, by means of molded locking lugs 13 behind an edge 14 of the frame 1 and by stops which are located in the Fig. 5 and Fig. As shown in figures 7, the label holder 6 can be fixed in place. This ensures that the label holder 6 is held in a pre-locked position in the frame 1 when delivered pre-assembled.

[0041] In the Fig. 5 and Fig. Figures 6 and 6 show a second and a third sectional view, as well as corresponding detail views B and C, of ​​a section of the cover frame 1 mounted on the wall 9, with the exemplary label holder 6, 7 inserted into the viewing window opening 24 (not visible here) via the back of the frame. The label 8 is inserted into the groove 22 provided in the respective label holder 6, 7. Detail views B and C also show the double-sided adhesive tape 10, 11 located between the mounting plate of the flush-mounted device insert and the label holder 6, 7, as well as the protective film 4, 5. The label holder 6, 7 is attached by means of the Fig. 4 locking lugs 13 shown, as well as by stops 15, 16 (see Fig. 5) or locking lugs 19 and edges 20 provided on the cover frame (see Fig. 6) held within the framework of 1.

[0042] After mounting the frame 1 on the wall 9 or on the flush-mounted insert and inserting the label 8, the protective films 4, 5 on the double-sided adhesive tape 10, 11 are pulled out of the frame 1. Arrows 17, 18 indicate the direction in which the protective films 4, 5 are pulled out to expose the second adhesive side of the double-sided adhesive tape 10, 11. The second adhesive side is the side of the double-sided adhesive tape 10, 11 that aligns and secures the pre-assembled unit on the mounting plate of the device insert.

[0043] By pressing down the label holders 6, 7, they are fixed to the mounting plate of the flush-mounted insert by means of the adhesive tape 10, 11. When pressed down, the label holders 6, 7 are secured by the adhesive tape 10, 11. Fig. The 2 shown webs 23 are guided in the frame 1, thereby determining the position of the label holders 6, 7 on the support plate.

[0044] The label holder 6, 7 sits recessed after being pressed down, whereby a flush finish with the frame surface is advantageously achieved only by the subsequently snapped-on viewing window 2, 3. This is in Fig. 8 shown.

[0045] Fig. Figure 7 shows a further section of the cover frame 1 of an exemplary installation device, mounted on the wall 9, before the label holder 7 is attached to the mounting plate of the device insert. The label holder 7, which is held in the viewing window 24 of the frame 1 (not visible here), is shown in a pre-locked position as the fourth sectional view and detail view D. A portion of the label holder 7 protrudes partially from the viewing window 24 of the frame 1, and the groove 22 for inserting the label 8 is located in this area. The label 8 can thus be easily inserted into the label holder 7 without having to remove it from the frame 1, since the groove 22 protrudes from the frame 1 in the pre-assembled state or in the pre-locked position.

[0046] On its side facing wall 9, the label holder 7 is provided with the double-sided adhesive tape 11. The double-sided adhesive tape 11 is provided with the removable protective film 5, which extends beyond the frame 1.

[0047] The label holder 7 is also secured here by means of its molded locking lugs 19, which are located in the Fig. As shown in Figure 4, the label holder 7 is positioned behind the edge of the frame 1, downwards, and fixed upwards by stops 21 provided on the frame 1. When the label holder 7 is now pressed into the viewing window opening 24 of the frame 1, the adhesive strip 10, 11 connects it to the support plate of the device insert in such a way that the label holder 6, 7 no longer protrudes beyond the cover frame 1.

[0048] Fig. Figure 8 shows a double cover frame 1 with a label holder 6 of the first embodiment arranged and attached in the upper area, and a label holder 7 of the second embodiment arranged and attached approximately in the middle, in a further sectional view, and detail views E and F of a section of the installation device with the label holders 6 and 7 of the first and second embodiments on the support plates 12 of the device insert. Here, the label holders 6 and 7 are already pressed against the wall 9 and adhered to the support plates 12 by means of the double-sided adhesive tape 10 and 11.

[0049] The support plates 12 are factory-mounted on the respective device insert on a device base of the flush-mounted installation device suitable for installation in a standard flush-mounted device box.

[0050] In this illustration, the protective films 4, 5 have already been removed, i.e., pulled out of the frame 1, and the label holders 6, 7, equipped with the labels 8, are positioned over the webs 23 located in the frame, which are in the Fig. 2 are shown, pressed down.

[0051] After the label holders 6, 7 are aligned and secured on the mounting plate 12, the transparent viewing windows 2, 3 are inserted or clipped into the corresponding recesses on the frame 1. The mounted viewing windows 2, 3 create a flush finish with the surface of the frame 1.
