Definitions

  • the invention relates to a device for attaching accessories to a ceiling lamp at a predetermined distance according to the preamble of claim 1.
  • Comparable devices are e.g. known from DE-C-493 015 or from GB-A-383 145.
  • Such accessories can be elements which, without an essential lighting function, primarily serve as design elements which are intended to emphasize the optical impression of the respective luminaire. In many cases, however, such accessories have primarily a lighting function.
  • such accessories can have different shapes, for example they can be designed as flat plates, rings or cones, which serve as eye-catchers and or shape the light emitted by the lamp, for example to lighten a surface area of the ceiling surrounding the ceiling lamp.
  • an appropriate device In order to attach accessories to a ceiling lamp at a specified distance, an appropriate device is required. This consists of one or more spacers, for example round rods, the ends of the ceiling lamp z. B. are detachable or non-detachable by a screw or welded connection. At the distant end of the spacer or spacers, the accessory is then also fixed, for example, by a screw connection. In some use cases a range of accessories that can be used alternatively. For reasons of easier shipping, it is also often desirable to send the ceiling light, an accessory and the associated fastening device unmounted. In all of these cases, it must be demanded that assembly or disassembly of the accessory is as simple as possible and without the need for expensive tools.
  • the present invention is therefore based on the object of specifying a further solution for a device of the type mentioned at the outset, with which an accessory on a ceiling light can be carried out safely, simply and above all without any substantial adjustment effort, possibly also by an inexperienced person, without complicated assembly instructions leaves.
  • the light-side receptacle of the device is designed as a cover ring, in which a holder is hung so that it encompasses the circumference of this cover ring in a clamped state. It is designed in such a way that when it is braced, it rests on the cover ring without tolerances and aligns itself with the ceiling light.
  • the bracket is formed in two parts. It has a hook-shaped upper part encompassing the edge of the cover ring, designed as a clamp, and a shoe-shaped lower part which, when these two parts are connected, lies against the underside of the cover ring with its front side.
  • FIG. 1 shows a recessed luminaire 2 inserted into a ceiling 1. Details of the design of such a lamp are only of minor interest in the present case. Therefore, only one lamp 4 inserted with its lamp bulb into the cutout of a hood-shaped reflector 3 is indicated schematically here.
  • the light exit opening of the ceiling lamp 2 is covered by a translucent pane 5, which can be designed as a filter and / or as a diffuser.
  • a cover ring 6 encompassing the disc 5 serves as a closure against the ceiling.
  • the ceiling light 2 shown in FIG. 1 is in itself only an example of a large number of known ceiling lights, which are commercially available as surface-mounted ceiling lights, recessed ceiling lights, but also as ceiling-mounted lights.
  • a first special feature of the luminaire shape shown in FIG. 1 lies in the design of the cover ring 6. It not only adjoins the ceiling 1 in order to cover the ceiling cutout required for the use of the luminaire, but also has an edge bead 61 at least in some areas, that protrudes laterally outwards. An edge groove 62 is embedded in the top of this edge bead 61 facing the ceiling 1. In addition, the underside of the cover ring 6 facing away from the ceiling 1 is designed as an inclined inclined surface 63.
  • a ring 7 suspended below the ceiling light 2 is indicated in broken lines in FIG. 1 as an example of such an accessory, which, as some schematically illustrated light beams 81 and 82 show, partially passes incident light or in peripheral areas for brightening the ceiling 1 reflected in the vicinity of the ceiling lamp 2.
  • this embodiment of an accessory as ring 7 is only to be understood as an example and is selected for illustration as representative of a large number of design options.
  • This accessory 7 is suspended below the ceiling lamp 2, ie how the device for fastening this accessory 7 to the ceiling lamp 2 is designed.
  • This device consists of a rod-shaped spacer 9, at the end facing the ceiling lamp 2, a two-part bracket 10 is fixed. At the other end of the spacer 9, a clamping element 11 is provided for receiving the corresponding accessory.
  • This device for attaching accessories to a ceiling lamp 2 at a predetermined distance can be compared to a tripod which carries the accessory 7 in an arrangement asymmetrical to the ceiling lamp 2.
  • FIG. 2 an enlarged detail compared to the representation of FIG. 1 shows more clearly how this device is fixed to the cover ring 6 of the ceiling lamp 2.
  • This section illustrates that the bracket 10 is formed in two parts, i. H. has an upper part designed as a clip 13 and a lower part designed as a shoe 14. Bracket 13 and shoe 14 of the holder 10 are connected to one another by a connecting screw 15 which engages in a threaded bore in the holder-side end of the spacer element 9. As will be explained in more detail, this holder 10 is suspended in the edge bead 61 of the cover ring 6, i. H. on this positively and non-positively.
  • bracket 13 of the bracket 10 is shown in each view to illustrate its structure.
  • the bracket 13 has a through hole 131 for receiving the connecting screw 15 including its screw head.
  • a hook-shaped extension 132 of the clamp 13 can be seen most clearly in FIG. 3, the outline of which is adapted to the shape of the edge groove 62 of the cover ring 6. With this hook-shaped extension 132, the clamp 13 engages around the cover ring 6 of the ceiling lamp 2 from above in the assembled state. The dimensions of the hook-shaped extension 132 and the edge groove 62 of the cover ring 6 are carefully coordinated.
  • the groove bottom of the edge groove 62 of the cover ring is preferably inclined to the outside, this inclination of the groove bottom of the edge groove 62 being approximately the inclination of the inclined surface 63, i. H. corresponds to the underside of the cover ring.
  • the engagement surfaces of the hook-shaped extension 132 of the clamp 13 are formed in a mirror-symmetrical manner.
  • the design of the underside of the clamp 13, ie the contact surface with the shoe 14, is of functional importance.
  • This underside has a roof-shaped, with a roof edge perpendicular to the hook-shaped Approach 132 stand up projection 133.
  • This projection 133 serves as the centering surface of the bracket 13 with respect to the shoe 14. If the axis of the through-hole 131 of the bracket 13 is the main axis of the bracket, FIG. 3 shows that the gable edge of the roof-shaped projection 133 is not exactly vertical with respect to this axis of symmetry , but is set against a defined angle of inclination ⁇ .
  • This inclination angle ⁇ means that the roof-shaped projection 133 gradually becomes flatter in the direction of the hook-shaped extension 132 of the clamp 13. The meaning of this detail will be explained later.
  • FIGS. 6 to 8 each show a view of the shoe 14 as the lower part of the holder 10.
  • the bore section 141 located in the upper part of the shoe 14 is exactly circular and corresponds in diameter to the diameter of the through bore 131 in the bracket 13 and is thus adapted to the shaft diameter of the connecting screw 15.
  • the lower bore section 142 forms a blind hole for receiving the upper end of the spacer element 9.
  • This lower bore section 142 is designed in its cross section as a circular segment, as the bottom view of the shoe, shown in FIG. 7, shows most clearly.
  • This cross section corresponds to the cross section of the spacer element 9, i. H. that this is also chamfered accordingly on one side.
  • the spacer 9 is exactly centered with respect to the shoe 14 and thus the entire bracket 13.
  • the instep surface 143 of the shoe ie its upper side facing the inclined surface 63 of the cover ring 6 in the assembled state, is also inclined in accordance with the inclination of this inclined surface.
  • the top surface 144 of the shoe 14 has, as in the side view of FIG most clearly recognizable, a V-shaped groove 145.
  • This V-shaped groove 145 of the shoe 14 corresponds mirror-symmetrically to the roof-shaped projection 133 of the bracket 13.
  • the bracket 13 and the shoe 14 are to be centered with one another with the aid of these two surfaces when they are assembled.
  • FIGS. 9 to 11 each show a view of the clamping element 11, which is arranged at the end of the rod-shaped spacer element 9 remote from the lamp, in order to serve as a receptacle for the accessory part 7.
  • the clamping element 11 has a through-bore 110 which, with a close tolerance, corresponds to the cross-section of the spacer element 9 which is chamfered on one side.
  • a first threaded bore 111 of the clamping element 11 is provided from its side facing away from the accessory part 7 for receiving a fastening screw, not shown in the drawing, for example a grub screw. With this fastening screw, the clamping element 11 is non-positively fixed on the spacer element 9.
  • the clamping element 11 has a U-shaped cross section formed by two legs 112 and 113 which are parallel to its longitudinal axis.
  • the lower leg 113 is chamfered on both sides and serves as a contact surface for the accessory 7 to be inserted at the edge between these two legs 112 and 113.
  • a further threaded bore 114 of the clamping element 11 is provided in the upper leg 112 parallel to the axis of the through bore 110. This threaded hole is also used to hold a fastening screw, with which the accessory part can be non-positively fixed between the two legs 112 or 113 of the clamping element 11.
  • FIG. 2 shows most clearly in the enlarged section how the device described is assembled.
  • the spacer element 9 is inserted from below into the shoe 14 of the holder 10 and, due to its cross-sectional shape, is rotatably secured in a defined position relative to the shoe 14.
  • the clip 13 of the bracket 10 is placed so that its roof-shaped projection 133 engages in the V-shaped groove 145 of the shoe 14.
  • the bracket 13 and the shoe 14 are also centered on one another.
  • the clip 13 is hooked with its hook-shaped projection 132 into the edge groove 61 of the cover ring 6, then the connecting screw 15 is tightened in the end threaded bore of the spacer element 9.
  • the bracket 13 spreads slightly relative to the shoe 14 such that these two parts of the bracket 10 are also positively from above and below on the cover ring 6 form-fitting and above all tolerance-free.
  • the connecting screw 15 By tightening the connecting screw 15, the device for fastening accessories to the ceiling lamp 2 is already clearly adjusted with respect to the cover ring 6 and thus the entire ceiling lamp 2. Now only the clamping element 11 has to be pushed onto the spacer element 9 and the respective accessory part 7 has to be fixed on the clamping element.
  • the device described above can optionally also be provided several times in order to fix an accessory 7, for example in a rotationally symmetrical arrangement on the ceiling lamp 2 or its cover ring 6.
  • the same clamping elements 11 can be used as in the embodiment described above.
