Definitions

  • the present invention relates to a lamp which can be set up by clamping between the floor and ceiling of a room.
  • Lights of this type are known under the name "tension light” and are described in documents US-A-2979.605 and DE-B-1.090.317.
  • the lights are designed so that their length in the axial direction exceeds the distance between the floor and ceiling of the room. By compressing the lamp against the force of a spring mechanism, the axial length can be shortened. The lamp can then be clamped between the floor and ceiling of the room, the restoring force of the spring mechanism preventing the lamp from falling over.
  • the present invention has for its object to provide a lamp which is designed as a tension lamp and can be set up in the manner specified above, which is fed with low voltage (for example 12V) and can be equipped with low-voltage halogen spotlights.
  • Low voltage lights are known per se from documents EP-A-171.326 and DE-B-1.135.576.
  • the installation of the lamp according to the invention is very simple.
  • the inventive design of those parts of the lamp that contain the tensioning mechanism, the safety regulations is particularly satisfied with regard to the insulation.
  • the lamp according to the invention is decorative and can be equipped with a larger number of low-voltage halogen spotlights.
  • the spotlights can be clamped in any position, which results in a variety of variations.
  • either the upper part or the lower part of the lamp can be extended. This makes it possible to manufacture the luminaire in one dimension as standard, so that the luminaire can be set up in an ordinary room with a room height of approximately 2.5 m.
  • the customer receives the standard-produced lamp in the standard size and also a corresponding extension piece, so that he can easily extend the lamp himself to the prescribed size.
  • the upper part of the lamp consists of a shell-like outer tube 1o, 24 which receives the two rod-shaped low-voltage busbars 12, 13.
  • the insert part 11 which is fixedly connected to the tube (for example by gluing) and which has 2 bores in the outer region for the passage of the busbars 12, 13.
  • an axial bore with an internal thread is provided in the insert part 11 for receiving a guide rod 14 extending through the tube 10, 24 in the axial direction.
  • the rod-shaped busbars 12, 13 are each provided with an external thread 15 at their upper ends. The ends of the busbars are each received by bores 18, 19 of a second displaceable insert 16.
  • the threaded ends 15 of the busbars 12, 13 are with the help screwed by nuts 17 to the insert part 16.
  • An axial bore 20 is provided in the insert part 16, which is stepped and has a larger cross section in the upper region than in the lower region.
  • the axial bore 2o receives a spacer 21 which is designed as a tube for the passage of the guide rod 14.
  • the guide rod 14 is screwed into an axial bore of a further insert part via an external thread, this insert part in turn being firmly connected to the upper end of the sheath of the plastic tube 24.
  • the insert part has an upper threaded bore for receiving a threaded bush 25 provided with an external thread 26.
  • the threaded bush 25 can be screwed in and additionally glued to the insert part and thus to the upper end of the plastic tube 24 in order to prevent loosening.
  • the upper end of the plastic tube 24 forms a plate 27, by means of which the lamp according to the invention is supported on the ceiling in the assembled state.
  • the plate 27 has a central bore 28 with an internal thread, so that it can be screwed onto the projecting piece of the threaded bush 25.
  • the clamping of the lamp according to the invention between the floor and ceiling is explained with reference to FIG. 4.
  • the lamp is designed so that the total length of the lamp exceeds the dimension between the floor and ceiling by a few centimeters.
  • the compression spring 23 is thus under tension and presses the plate 27 against the ceiling, so that the lamp is securely clamped between the ceiling and floor. Since the busbars 12, 13 are only fed by a low voltage of 12 V, insulation is not necessary. As can be seen from FIG. 4, a plurality of luminaire spotlights 53 can be clamped to the busbars 42, 43 via suitable clamping parts 52 in any position.
  • the clamping parts are the subject of the separate older application DE-A-37 42 2o6 by the applicant.
  • the two busbars 42, 43 are received in an analogous manner by a corresponding pipe part 40, preferably made of plastic, at the lower end of which there is a plate 39 which forms the bearing surface for the floor.
  • a housing 36 can be provided for a transformer.
  • the supply current with mains voltage reaches the transformer via line 37 and is then transformed into the 12V low voltage.
  • the transformer does not have to be integrated in the lamp, but can just as well be a separate component.
  • the busbars 42, 43 are not axially displaceably guided in the plastic tube 4o of the lower part of the lamp, but rather are rigid.
  • the upper part of the luminaire is resilient.
  • the lower part of the lamp is constructed similarly to the resilient upper part of the lamp.
  • central guide rod 44 which has an external thread 38 in its upper section and can thus be screwed to the upper insert part 41, which has a corresponding bore with an internal thread.
  • the two busbars are also received in the upper section in corresponding bores of the insert part 41.
  • the two busbars 42, 43 each have an external thread 45 in the lower end region.
  • the lower insert 46 in turn has three holes, namely a central axial hole 50 for the passage of the guide rod 44 and two further holes 48, 49 in the outer region for the passage of the end pieces of the busbars 42, 43.
  • the holes 48, 49 are in the The upper area is enlarged in cross section so that a form-fitting reception of correspondingly thickened sections of the busbars 42, 43 which are located above the thread 45 can take place. An abutment is thus provided for the end sections of the busbars 42, 43.
  • the busbars 42, 43 are then fixed to the insert part 46 with the aid of the nuts 47.
  • the nuts 47 have at the same time terminals 51 in the manner of luster terminals, so that the current-carrying low-voltage lines can be clamped there.
  • FIG. 3 now shows how the upper part of the lamp can be easily extended if the distance between the floor and ceiling is greater than the length of the lamp, so that clamping the lamp is not easily possible.
  • the upper part of the lamp is, as a comparison of Figures 3 and 1 shows, also constructed in the extended version up to the upper end of the guide rod 14 and the outer plastic tube 24. If the upper part of the lamp is to be extended upwards starting from the standard version shown in FIG. 1, the plate 27 is first unscrewed. The threaded bush 25 then protrudes somewhat beyond the end of the plastic tube 24 and the external thread 26 of the threaded bushing is exposed in the upper section.
  • a type of extension rod 30 is then first screwed onto the threaded sleeve 25, which has at its lower end an area with a larger external cross-section and internal thread 34, that is to say a molded-on threaded sleeve 33.
  • the extension rod 3o At its upper end, the extension rod 3o in turn has an external thread 35.
  • a tube extension piece 29, preferably made of plastic, is required to extend the outer tube 24 to extend the lamp.
  • the outer tube has a shoulder 31 at its upper end, so that a guide for the end of the tube extension piece 29 is given. After placing the pipe extension piece, the plate 27 can then be screwed on again.
  • the plate has a short socket 32 with a slightly smaller diameter than the pipe extension piece 29, so that the short socket 32 can be received by the pipe extension piece 29 and thus a guide is also available for the plate 27.
  • the central bore 28 with an internal thread formed in the plate enables the plate 27 to be screwed onto the external thread 35 of the extension rod 3o, which protrudes somewhat above the tube extension piece 29. So there is a simple possibility to extend the luminaire in a corresponding way if the room height exceeds a standard dimension of 2.5o m or 2.6o m.
  • the extension of the lamp can be done by the customer himself.
  • the tube extension piece 29 is supplied together with the extension rod 3o by the luminaire manufacturer in various standard lengths, for example 1o cm, 2o cm etc.
