Description

[0001] The invention relates to a frameless electrical / electronic installation device for building installation technology with an insert and an attachment, wherein the insert comprises a base part which is fastened to a support plate and is provided for the electrical connection of at least one electrical functional module, and the support plate fastens the insert to an installation box, wherein the attachment has a universal support element for positioning on the support plate of the insert, wherein the support element has at least two guide extensions which are supported on the support plate, wherein the universal support element has a receptacle for an installation device-specific central insert made of plastic, wherein the central insert is framed at the rear by the support element and at the front by a design plate having at least one opening.

[0002] Furthermore, the invention relates to an arrangement of at least two adjacent such frameless electrical / electronic installation devices.

[0003] Electrical / electronic installation devices such as switches or sockets typically consist of a (flush-mounted) insert that is installed in an installation box using a support plate. The insert includes a base part attached to a support plate. This base part is intended for the electrical connection of at least one electrical functional assembly, while the support plate secures the insert to an installation box.

[0004] As part of an attachment, a central insert, such as a rocker switch or the center piece of a socket, is attached to the support plate. A cover frame surrounding the central insert is attached to the support plate. The cover frame not only serves the visual function of covering the sides of the central insert and the support plate, but also performs a positioning function such that the cover frame ensures centralized insertion and fixation of the attachment.

[0005] The installation process for such electrical / electronic installation devices (for example, as known from www.jung.de / at / 852 / produkte / technik / steckdosenl) that feature a cover frame is often associated with a multitude of individual parts and synchronized installation steps, so that the installation process for such electrical / electronic installation devices that feature a cover frame is perceived as complex. Furthermore, the multitude of individual parts used results in a low use of identical parts and thus relatively high manufacturing costs. Furthermore, the use of cover frames that cover the central insert all the way around is not considered particularly visually appealing, as a circumferential gap is created between the central insert and the cover frame.

[0006] Also known are frameless electrical / electronic installation devices, which do not have a cover frame surrounding the central insert. However, these have the disadvantage that they require a multitude of different, coordinated support elements and design plates to accommodate the central inserts, which results in high manufacturing costs.

[0007] DE 10 2016 119 608 A1 discloses a generic electrical / electronic installation device which is designed as an illuminated card switch which has a modular design and which enables a varied illumination of the card switch in a simple manner.

[0008] Based on this discussed prior art, the invention is based on the object of creating a frameless electrical / electronic installation device which is characterized by low installation effort and low manufacturing costs.

[0009] This object is achieved by a frameless electrical / electronic installation device according to main claim 1.

[0010] The core idea of ​​the invention is, on the one hand, to create a frameless electrical / electronic installation device, wherein the attachment has a universal support element for positioning on the support plate of the insert. The universal support element, which has a receptacle, is therefore one and the same element, which can accommodate different installation-device-specific central inserts, so that the invention already makes it possible to increase the use of identical parts. It makes sense to use a standard size for the receptacle dimensioning so that even conventional central inserts and / or the tools used to manufacture conventional central inserts can be used. The inventive idea is rounded off by the fact that the central insert is framed at the rear by the support element and at the front by a design plate having at least one opening.This enables a frameless design, with the central insert being framed in a particularly advantageous manner by the universal support element and the design plate, so that the three aforementioned components (central insert, support element and design plate) can be pre-assembled at the factory to simplify installation.

[0011] According to the invention, the design plate is made of metal. A metallic design plate offers the advantage of a particularly appealing appearance and feel – however, the conductivity of the metal poses a safety risk. Therefore, according to the invention, the holder for the plastic carrier element is preferably formed by retaining webs, wherein the retaining webs interact with the central insert in such a way that an effective insulating surface is created with respect to the metallic design plate. Thus, the design plate is completely shielded from the base part by the carrier element and the central insert, and the insulating properties of the plastic are utilized. This significantly reduces the safety risk posed by the metallic design plate.

[0012] According to a preferred embodiment of the invention, the central insert has a quadrangular contour that complements the support element's receptacle. Particularly preferably, the quadrangular contour is a square, which offers the advantage that both horizontal and vertical installation is possible.

[0013] In a further development of this particularly preferred embodiment of the frameless electrical / electronic installation device, the square has an edge length of essentially 55 mm. This standard dimension for the support element holder corresponds to the dimensions of conventional central inserts, thus maximizing the use of common parts and minimizing manufacturing costs.

[0014] According to a particularly advantageous embodiment of the frameless electrical / electronic installation device, the support element, the central insert, and the design plate are pre-assembled, in particular glued, into a single assembly. This significantly simplifies on-site installation by the electrician or user. The frameless design not only eliminates the need for a cover frame, which would also have to be secured to the support plate using its own fixing devices, but also effectively fuses the central insert and design plate into a single component due to the pre-assembly. In this respect, this embodiment of the invention offers a particularly high degree of ease of installation for the user.

[0015] According to a preferred embodiment of the design panel according to the invention, it is made of metal, wood, plastic, or glass. This allows the appearance and feel to be customized as desired.

[0016] Furthermore, the invention relates to an arrangement of at least two adjacent frameless electrical / electronic installation devices according to the invention. This arrangement is characterized in that the installation devices have a one-piece design plate. Thus, the advantages of the frameless electrical / electronic installation device according to the invention can also be extended to adjacent frameless electrical / electronic installation devices.

[0017] According to a further development of this inventive arrangement of at least two adjacent frameless electrical / electronic installation devices according to the invention, which is characterized by particularly high flexibility, the support element can be expanded from modular elements in the manner of a puzzle. The support element is formed by two end pieces and a variable number of middle pieces connecting the end pieces.

[0018] The invention is described below with reference to various exemplary embodiments and the accompanying figures. They show: Fig. 1: a perspective exploded view of the design plate according to the invention, the central insert and the universal support element, Fig. 2: a perspective view of the frameless electrical / electronic installation device according to the invention, which is designed as a toggle switch, Fig. 3: a plan view of the frameless electrical / electronic installation device according to the invention according to Fig. 2, Fig. 4: a perspective exploded view of the design plate according to the invention, the central insert and the universal support element, for an arrangement according to the invention of two adjacent frameless electrical / electronic installation devices, Fig. 5: a perspective view of the arrangement according to the invention of two adjacent frameless electrical / electronic installation devices, wherein a first installation device is designed as a toggle switch and a second installation device is designed as a socket, and Fig. 6: a plan view of the arrangement according to the invention according to Fig. 5.

[0019] In the various figures, identical parts are always provided with the same reference symbols and are therefore usually named or mentioned only once.

[0020] Fig. 1 shows a perspective exploded view of the design plate 1 according to the invention, the central insert 2 and the universal carrier element 3.

[0021] The universal support element 3 according to the invention has at least two guide extensions 4, which are located on the (in Fig. 1 not shown) support plate 5, wherein the universal support element 3 has a receptacle AN for a (installation device-specific) central insert 2 made of plastic, wherein the central insert 2 is enclosed at the rear by the support element 3 and at the front by a design plate 1 having at least one opening 6. In the present case, the central insert 2 has a quadrangular contour, here as a square with an edge length of 55m. In the present case, the design plate 1 is made of metal and the receptacle AN of the plastic support element 3 is formed by holding webs (see inside of the receptacle AN), wherein the holding webs interact with the central insert 2 in such a way that an effective insulation surface is created with respect to the metal design plate 1, wherein in particular the metal design plate 1 is completely shielded by the support element 3 and the central insert 2 with respect to the base part S.

[0022] Fig. Figure 2 shows a perspective view of the frameless electrical / electronic installation device I according to the invention, which is designed as a toggle switch. This electrical / electronic installation device I comprises an insert E and an attachment A, wherein the insert E comprises a base part S secured to a support plate 5, which is provided for the electrical connection of at least one electrical functional module, and the support plate 5 secures the insert E to an installation box. In the present case, the support element 3, the central insert 2, and the design plate 1 are preassembled into an assembly, in particular glued, so that on-site assembly is possible with particularly few parts and effort.

[0023] In Fig. 3 is a plan view of the frameless electrical / electronic installation device I according to the invention according to Fig. 2, in which it can be seen that the frameless electrical / electronic installation device I according to the invention does not have a cover frame for covering a support plate 5 and / or the circumferential side surfaces of the support element 3.

[0024] A perspective exploded view of the design plate 1 according to the invention, the central insert 2 and the universal support element 3, for an arrangement II according to the invention of two adjacent frameless electrical / electronic installation devices I is shown in Fig. 4. The design plate 1, which is constructed in one piece, has two openings 6 – one for a toggle lever of a toggle switch and one for a socket. The one-piece design plate 1 prevents the formation of a gap, such as would also be caused by a cover frame in previously known electrical / electronic installation devices, without incurring the further disadvantages of previously known arrangements of at least two adjacent electrical / electronic installation devices I.

[0025] Fig. 5 shows a perspective view of the arrangement II according to the invention of two adjacent frameless electrical / electronic installation devices I, wherein a first installation device I is designed as a toggle switch and a second installation device I is designed as a socket.

[0026] In Fig. 6 is a plan view of the arrangement II according to the invention according to Fig.5, in which the one-piece nature of the design plate 1 and the framelessness can be clearly seen.

[0027] The invention is described using exemplary embodiments. Without departing from the scope of the applicable claims, numerous further possibilities for implementing it will become apparent to a person skilled in the art without the need for detailed explanation within the scope of these statements.
