Definitions

• the invention relates to the field of ceiling sockets with a hanging hook for hanging lights.
• the invention relates to a ceiling socket for ceiling lights with a socket, a carrier piece which is accommodated therein and has electrical clamping contacts and can be fastened on the ceiling and to which a suspension hook having an anchoring section is pivotably articulated.
• Such a ceiling socket is known from DE-GM 90 12 349.2.
• This known ceiling socket consists of a socket that can be used in the ceiling plaster or can be placed on the ceiling in the case of a surface-mounted arrangement, a support piece made of plastic which has electrical clamp contacts, a cover plate which can be fixed therein and a hinged hanging hook which is held on the support piece and through the cover plate to the outside protrudes.
• the suspension hook protrudes outwards through a T-shaped opening in the cover plate and, with its anchoring part in the non-use position, can be folded down into a depression introduced into the cover plate. In the position of use, the suspension hook can be pivoted into a hanging position perpendicular to the cover plate.
• the anchoring part of the suspension hook is articulated in relation to the socket or the carrier piece, so that the suspension hook protrudes centrally from the ceiling socket in its position of use. Due to the centered articulation of the hanging hook, the radius of such a ceiling socket is largely determined by the size of the hanging hook. The suspension hook can hardly be made smaller due to the demands placed on these with regard to its load bearing, even if one tries to provide the smallest possible ceiling socket with a load bearing of the same size. It is desirable to design ceiling sockets as small as possible so that the design of a ceiling light is not impaired by an oversized ceiling socket.
• Another ceiling socket is known from DE 27 30 859 A1. This known ceiling socket comprises an installation box in which an electrical socket is arranged in the center. A hanging hook is provided adjacent to the socket and thus off-center, which is fastened through the installation box with a dowel on the wall side.
• the hanging hook has a joint with which it can be subdivided into an anchoring section - the section which extends into the dowel - and a hanging section - the hook-shaped section on which a lamp can be suspended.
• the suspension section is connected to the anchoring section via a hinge so that the suspension section lies flat on the top of the socket in its non-use position and is pivoted out in its use position and is arranged so as to project downward adjacent to the socket. So that the suspension hook, the anchoring part of which is arranged next to the socket, is provided somewhat to the center of the socket, it has an angle so that the suspension hook is Z-shaped in its position of use.
• the invention is therefore based on the object of providing a ceiling socket for ceiling lights which is not only for use with a large load. Recording can be used, but at the same time has the smallest possible dimensions.
• the anchoring section of the suspension hook is arranged displaceably in a guide, so that the anchoring section can be moved from a hanging or use position into a non-use position spaced from it.
• the anchoring piece of the hanging hook is arranged essentially centrally in its hanging position with respect to the socket or the carrier piece.
• the suspension hook with its anchoring piece can be pushed into a non-use position, the anchoring piece being arranged off-center in the non-use position.
• the anchoring piece is in the non-use position at a distance from the essentially central hanging position.
• the size of the hanging hook no longer determines the radius of the ceiling socket, but only the diameter of the latter. Such ceiling sockets can therefore be made much smaller than the aforementioned.
• the anchoring piece is T-shaped and engages for guidance in a U-shaped fastening piece, in the opposite leg of which an elongated hole-like opening is made, through one end of which the hanging position and through the other end of which the non- - Use position of the suspension hook is determined.
• a slot-like guide is expediently inclined from its hanging position to the non-use position to the can or to the ceiling. Such an arrangement ensures that the unfolded suspension hook is always in the intended hanging position end of the guide, at least under load.
• the end of the slot-like guide on the non-use position side corresponds essentially in diameter to the diameter of the anchoring piece of the suspension hook.
• the clear width of the remaining guide sections is designed with a certain amount of play with respect to the diameter of the anchoring piece, in order to prevent canting when the suspension hook opens.
• the hook section of the suspension hook angularly bordering the anchoring piece.
• the hook section of the suspension hook can then be arranged essentially flush with the outside of the carrier piece cover in its folded position.
• Fig. 5 the ceiling socket of Figure 1 in a section C-B of
• FIG. 1 shows a ceiling socket 1 with a cover frame 2, a canopy 3 and a cover plate 4 provided as a support piece cover.
• a support piece 5 is arranged beneath the cover plate 4, in which a suspension hook 6 with its anchoring part 7 can be pivoted is articulated.
• the cover plate 4 has plug-specific openings 8 for engaging through plug contact pins of a plug for establishing an electrical contact with the electrical clamping contacts assigned to the carrier piece 5.
• the central opening 9 with respect to the connector arrangement 8 is provided for inserting the connector contact pin provided for the protective conductor.
• Two further openings 11 serve for the unmistakable insertion of a plug.
• the opening 12 is provided for locking an inserted plug by means of a locking bracket.
• a hook receptacle 13 is also introduced into the cover plate 4, into which the suspension hook 6 can be folded with its holding section 14 in its non-use position.
• latching feet 15 are provided both for fixing the cover plate 4 on the carrier piece 5 and for holding the cover frame 2. Between the pair of snap-in feet 15 there is an operating opening 16, into which a tool can be used if the holding position of the cover frame 2 is to be changed or if the cover frame 2 is to be removed from the ceiling socket 1.
• the configuration of the latching feet 15 can be seen from the sectional illustration in FIG.
• the locking feet 15 are integrally formed on the base plate 17 of the cover plate 4.
• the ends of the locking feet 15 are provided with a barb-like locking lug 18 which engage in an undercut located on the carrier piece 5.
• the cover plate 4 has dowel-like detent elements 20 which engage in corresponding bores in the carrier piece 5 and serve to fasten the cover plate 4 on the carrier piece 5.
• a groove 19 is introduced into the locking feet 15, which serve to fix the cover frame 2.
• the cover frame 2 shown in section in Figure 3 consists essentially of a rosette-like cover ring 21, the underside of which System is provided on the ceiling, a groove-shaped canopy receptacle 22 and from holding feet 23 which are attached to positions corresponding to the locking feet 15 of the cover plate 4.
• a groove 24 corresponding to the groove 19 is likewise introduced on the inside into the holding feet 23.
• the built-in ceiling socket 1 is shown in Figure 4. From this figure it is also clear that a socket 25 is assigned to the ceiling socket 1, which is designed as a flush-mounted box in the illustrated embodiment. Received in the box 25 is the carrier piece 5, on the one hand the electrical clamping contacts, of which the clamping contact assigned to the protective conductor is shown in FIG. 4, and on the other hand the suspension hook 6 with a fastening piece 27 having a guide 26 are assigned.
• the carrier piece 5 and the cover plate 4 are made of a plastic that complies with the German VDE standards.
• the fastening piece 27 is made of metal.
• the guide 26 of the fastening piece 27 is designed as an elongated hole, in which the anchoring part 7 of the suspension hook 6 is slidably guided.
• FIG. 4 shows the hanging hook 6 in its retracted non-use position, so that the anchoring part 7 is located at the end 28 of the opposite guides 26 that is not in use.
• the width of this end 28 is essentially adapted to the diameter of the anchoring part 7 so that the suspension hook 6 is fixed in this position.
• the clear width of the remaining sections of the guide 26 are formed with sufficient play larger than the diameter of the anchoring part 7.
• the ceiling socket is 1 in a cutting plane offset by 90 degrees shown again in FIG. 5.
• the T-shaped configuration of the anchoring part 7 of the suspension hook 6 can be seen from this figure.
• the suspension hook 6, together with its anchoring part 7, is in its hanging position in the figure shown.
