Definitions

  • the invention relates to a fastening system for a lamp for tool-free mounting of a lamp element on a support unit by means of two complementary hooking means, comprising at least one element hook which is assigned to the lamp element, and at least one support hook which is assigned to the support unit, wherein by means of a defined mounting movement of the lamp element in a first direction of movement towards the support unit, an interlocking of element hooks and support hooks can be effected for the purpose of fastening the lamp element in an operating position.
  • the invention relates to a fastening element and a luminaire comprising a support unit, a luminaire element and at least one fastening element.
  • Luminaires of the type mentioned are surface-mounted luminaires, recessed luminaires, hanging luminaires, inlay luminaires, panel luminaires, etc. They usually consist of a support unit, for example a housing and a luminaire element, which can be designed as an insert.
  • the luminaire element, or the housing can be connected/inserted into the support unit.
  • the support unit is mounted, for example, under a building ceiling.
  • Existing cables for supplying electrical energy are fed into the support unit and installed therein.
  • the lighting element is then connected to the electrical cables in the support unit.
  • electrical cables are also provided in the lighting element.
  • Further components of a lamp can be provided in the lighting element, for example lamps, in particular circuit boards with LEDs, an operating device, a radio module, etc.
  • the lighting element preferably has a transparent cover which closes an interior of the lighting element in which the lamp is arranged, wherein the lamp emits light outwards through the cover when the lamp is in an operating state.
  • the lighting element preferably has an optical element for influencing a radiation direction of the light emitted by the lamp, wherein in particular the optical element is arranged in the preferably provided interior or integrated in the preferably provided cover.
  • a generic fastening system is known from the EN 2 022 009 A1 known. It has an element hook which is assigned to a lighting element and a support hook which is assigned to a support unit. In this state of the art, the element hook is arranged so that it can be moved mechanically relative to the lighting element and a spring exerts a pre-tension. An extension protrudes outwards from the lighting element as an operating element for the movable element hook.
  • the invention is based on the object of providing a fastening system which at least partially eliminates at least one of the problems of the prior art described above.
  • the object is achieved in that either the element hook or the support hook is designed as a rigid hooking means, that either the support hook or the element hook is designed as a movable hooking means in order to allow an opening position by means of this mobility, so that a hooking engagement of the support hook with the element hook can be established, with the proviso that at least one locking means is provided for the movable hooking means for the purpose of tool-free and thus particularly simple disassembly of the lighting element, and that the movable hooking means can be locked in its opening position with the aid of the locking means.
  • the inventor has found that it is advantageous for handling the lighting element during disassembly if the interlocking engagement can be completely removed so that the lighting element can be removed from the support unit without hindrance, without getting caught or jammed in the support unit.
  • the movable interlocking means carries out at least a significant portion of the movement to be carried out by the interlocking means in order to get from the operating position to the opening position.
  • the rigid interlocking means does not carry out any movement, only the movable interlocking means.
  • One of the support hooks and element hooks can be designed as the rigid interlocking means, the other as the movable interlocking means.
  • the support unit and the lighting element can be designed as elongated bodies.
  • the support unit simply has a U-shaped cross section, comprising a base section and two side walls that extend in the longitudinal direction of the support unit.
  • the base section of the support unit can be used to mount the support unit to a building surface, such as a wall or ceiling.
  • At least one support hook is arranged on one side of a side wall of the support unit and the lighting element has an associated element hook. This is possible, for example, if there is close contact between an inner side of the side wall of the support unit and a side wall of the lighting element. The close contact can provide guidance between the side walls or a slight tilting in order to achieve a holding effect without having to provide any further hooking engagement.
  • the support units and the lighting element can also have a different shape, for example a cylindrical shape.
  • the first direction of movement for the luminaire element towards the support unit intended for assembly is preferably a translational joining movement.
  • tool-free disassembly is provided by means of a first disassembly step starting from the operating position of the lighting element further in the first direction of movement, whereby the rigid hooking means is designed to release the movable hooking means from the hooking engagement during this first disassembly step and to move it in the direction of its opening position.
  • This can be ensured, for example, by sliding surfaces of the rigid and movable hooking means that correspond to one another and by means of which they rest against one another during the first disassembly step.
  • At least one of the hooking means can have a sliding surface designed as an inclined surface on which the sliding surface of the other hooking means slides during the first disassembly step and/or one of the sliding surfaces can be deflected in a spring-elastic manner.
  • the hooking engagement can be released by continuing to move the lighting element in the same direction of movement as during assembly of the lighting element and without having to reach and operate an additional operating element.
  • the mobility of the movable hooking means can be provided in a simple manner using spring elasticity or by means of a joint.
  • a spring elastic movable hooking means works in any spatial installation position.
  • a hooking means that provides a joint for its mobility is simply designed and arranged in such a way that gravity can be used for a hooking engagement. This is useful if the hooking means can be arranged in a hanging position so that its center of gravity is below the joint. If the light is mounted on the ceiling, a spring effect is not absolutely necessary for the movable hooking means. If the light is mounted on the ceiling, the mobility of the hooking means can be provided with a swivel joint so that one hook end of the hooking means can come into the hooking engagement actuated by gravity.
  • the locking means can also be brought into engagement with the movable hooking means by a spring device to ensure locking or, alternatively, can reach its locking position without spring action and only by gravity if it has a swivel joint for this purpose and the installation position is suitable for this.
  • the movable hooking means has a first spring section which provides the mobility of the movable hooking means for moving between the operating position and the opening position.
  • the first spring section can ensure that the lighting element can be easily mounted and removed from the support unit.
  • the locking means or the movable hooking means has a second spring section which can be deflected in a spring-elastic manner in order to lock the movable hooking means in the open position, i.e. to lock the hooking means with the locking means.
  • the second spring section thus provides the mobility of the movable hooking means or the locking means required for locking.
  • the second spring section is preferably spaced apart from the first spring section.
  • the spring sections can preferably be deflected in a spring-elastic manner independently of one another starting from their respective rest position.
  • the movable hooking means and/or the locking means has a further, in particular third, spring section, by means of which it can be fastened to the support unit or to the lighting element, in particular can be fastened detachably.
  • the hooking means and/or the locking means can be fastened or mounted by moving the further spring section and thus deflecting it. This can make it particularly easy to mount and/or advantageously provide non-destructive detachability to or from the support unit or the lighting element.
  • the movable hooking means and the locking means are formed together by a fastening element and can thus be fastened together in a single assembly step to the support unit or to the lighting element by means of the further spring section, wherein in particular the connecting means explained in more detail below comprises the further spring section.
  • the further spring section can be deflected in a spring-elastic manner starting from its rest position independently of the other spring sections.
  • the rigid hooking means is provided with a pushing surface and the movable hooking means has two sliding surfaces, both of which interact with the pushing surface, wherein a first sliding surface is provided for the purpose of opening the movable hooking means during the establishment of the hooking engagement and the second sliding surface is provided to provide an opening of the movable hooking means during disassembly of the lighting element.
  • the pushing surface of the rigid hooking means presses against the first sliding surface of the movable hooking means and is guided along it, the hooking means moves in the direction of its opening position, up to a turning point. At the turning point of the movement, it automatically reverses. In this way, the movable hooking means automatically comes into positive engagement with the rigid hooking means of the lighting element.
  • the locking device conveniently comprises a locking hook and a sliding element, wherein the movable hooking means has a thrust surface and a latching area for the locking hook.
  • the locking hook and sliding element are integrated together in a one-piece component and each form a section of the component.
  • the term "sliding element" can thus designate a section of the component.
  • a free end of the locking hook is simply used as a sliding element. The locking in the open position is ensured by the interlocking of the locking hook and latching area.
  • the thrust surface of the movable hooking means acts against the sliding element of the locking means and an opening movement can be generated until the locking hook reaches a reversal point and automatically engages and locks in the engagement area of the movable hooking means.
  • a second disassembly step of the lighting element in the opposite direction of movement to the first disassembly step is required in order to remove the lighting element from the support unit.
  • the movable hooking means has two hooking sections.
  • the rigid hooking means has a shape which can interact with both hooking sections of the movable hooking means and in order to provide a sufficiently stable hooking engagement. In the operating position, both are hooked to the rigid hooking means for the purpose of fastening the lighting element.
  • the hooking sections are preferably spaced apart from one another, so that in an area lying between the hooking sections, the movable hooking means in the operating position is not in engagement with the rigid hooking means.
  • the locking means is arranged in the open position between the hooking sections, i.e. at least one section is arranged between the hooking sections.
  • the preferably provided locking hook is arranged in the open position between the hooking sections.
  • the locking means has two locking sections, wherein in the open position the movable hooking means is arranged between the locking sections. In the operating position, both are hooked to the movable hooking means for the purpose of locking.
  • the locking sections are spaced apart from one another, so that in an area lying between the locking sections the movable hooking means is not in engagement with the locking means in its open position.
  • the movable hooking means is arranged in the open position between the locking sections, i.e. at least one section is arranged between the locking sections.
  • the two interlocking sections of the movable interlocking means are arranged next to one another.

  • the interlocking sections each have a partial section of the first spring section explained, in particular forming the first spring section or being connected to one another by a further partial section of the first spring section.
  • the locking area is conveniently located between the two hooking sections of the movable hooking means.
  • This The symmetrical design of the movable interlocking device promotes an even load on both interlocking sections. In order to create the interlocking engagement, both are moved evenly and function synchronously.
  • a further advantage is seen when the movable hooking means and the locking means are combined to form a fastening element.
  • This fastening element is designed in such a way that it can be arranged either on the support unit or on the lighting element.
  • the hooking means and the locking means are thus both formed by a coherent element, namely the fastening element, and are therefore particularly easy to assemble, since only one coherent element needs to be mounted on the support unit or on the lighting element.
  • the fastening element is preferably designed in one piece, so that it only consists of a single component and is not composed of several components.
  • the rigid hooking means must be designed to complement the fastening means and is suitably designed so that it can also be attached either to the support unit or to the lighting element.
