Definitions

  • Retaining springs of the generic type are used to produce lights that have a mounting body and a mounting rail.
  • the mounting rail is used to fix the light on a component, for example a ceiling, with various components of the light being arranged in the mounting rail, for example electrical cables, operating devices, radio modules, etc.
  • Components of the light are usually attached to the mounting body, for example circuit boards LEDs, radio modules, electrical lines and / or operating devices.
  • the mounting rail is usually first attached to the component and then the mounting body, which is equipped with the named components of the lamp, is fixed to the mounting rail so that the mounting rail and mounting body form an interior space in which the essential elements of the Luminaires are arranged, for example circuit boards, operating devices, etc.
  • the support rail and mounting body are each designed to be elongated in a longitudinal direction, preferably the longitudinal extent is at least 5 times the extent perpendicular to the longitudinal direction.
  • the support rail usually has a cross section perpendicular to the longitudinal direction, which is open at a vertical end along a vertical direction and is delimited along a transverse direction by two support rail side walls which are connected to one another by a support rail base running along the transverse direction and which extend vertically away from the support rail base extend.
  • the mounting rail is usually attached to a component via its mounting rail base.
  • the mounting body is usually arranged at the open vertical end of the mounting rail, so that the mounting body, together with the mounting rail, forms an interior space that is circumferentially closed off by the mounting rail and mounting body perpendicular to the longitudinal direction.
  • the enclosure of the interior which is formed by the support rail and mounting body, can be interrupted in sections, for example to allow access to the interior, for example for air supply.
  • the mounting body often has a cross section perpendicular to the longitudinal direction, which comprises a mounting body base extending in the transverse direction and mounting body side walls extending vertically away from the mounting body base on the two transverse sides of the mounting body base.
  • a mounting body retaining anchor in particular designed as a mounting body projection, is preferably provided on each of the mounting body side walls.
  • an in particular as is preferably on each of the mounting rail side walls Support rail projection formed support rail retaining anchor provided.
  • the mounting body base is preferably arranged at the open end of the support rail.
  • the mounting rail and mounting body are generally usually produced separately from one another.
  • the mounting rail and / or mounting body are each made from a sheet metal by forming.
  • Retaining springs of the generic type are used to enable the mounting body to be fixed to the mounting rail as simply as possible and at the same time as robustly as possible, and also to enable the mounting element to be easily dismantled from the mounting rail. Because for maintenance purposes it is necessary that the assembly body can be removed from the mounting rail so that a technician has access to the interior and can, for example, replace lamps, circuit boards or the like.
  • retaining springs of the generic type are already known which have two retaining sections lying opposite one another in the transverse direction, each of the retaining sections comprising a base region on the one hand and holding regions on the other. The base areas of the holding sections merge into one another, and the holding areas are each designed as a holding projection extending outward in the transverse direction.
  • a holding anchor in particular a holding projection, is provided on each of the two holding sections opposite each other in the transverse direction, the holding anchor of each holding section extending outward and thus preferably away from the opposite holding section.
  • a spring is usually made from a one-piece sheet metal part or from sheet metal parts that are guided to one another. This sheet metal part is then with the base areas of the holding sections on the assembly body fixed, wherein the retaining spring can be pressed with its base areas against the mounting body base via the mounting body retaining anchors and can thereby be fixed to the mounting body.
  • the holding areas are then designed to engage behind the aforementioned mounting rail retaining anchors in order to fix the mounting body on the mounting rail in order to press the mounting body and mounting rail against one another along the vertical.
  • the mounting body When the mounting body is mounted on the mounting rail, the mounting body is usually moved vertically towards the mounting rail, the mounting body being located vertically under the mounting rail and being moved upwards towards the mounting rail during assembly.
  • each of the retaining sections of the retaining spring which is attached to the mounting body with the base areas of the retaining sections, is assigned to one of the mounting rail retaining anchors and, after assembly, a retaining area of the respective retaining section is arranged above the mounting rail retaining anchor assigned to it and vertically downwards against the mounting rail retaining anchor pressed, the retaining spring ensures that the mounting body and mounting rail are held vertically pressed against each other.
  • Each of the mounting rail holding anchors is usually provided on one of the mounting rail side walls, each of the two opposing holding sections being assigned to one of the mounting rail side walls and thus one of the mounting rail holding anchors.
  • the mounting rail holding anchors are usually designed as mounting rail projections and in such a way that each of the mounting rail projections is located in a specific mounting rail side wall Transversal direction extends to the respective opposite support rail side wall.
  • mounting rail retaining anchors can also be designed, for example, as a recess, in particular as a hole, in the respective mounting rail side wall.

  • Such retaining springs of the generic type enable the mounting body to be reliably fixed on a support rail. It must be taken into account that there are sometimes high forces acting between the mounting body and the mounting rail, because on the one hand the mounting body carries essential lighting elements of the luminaire and thus has a not inconsiderable weight and on the other hand with jerky movements of the component, such as those in ceilings in Buildings can occur with jerky loading of the ceilings, high acceleration can occur along the vertical direction of the mounting body relative to the mounting rail, which, due to the weight of the mounting body, can lead to a high vertical force on the mounting body away from the mounting rail.
  • retaining springs of the generic type are usually constructed in a complicated manner, so that sheet metal with a not inconsiderable thickness and two-dimensional extension is used for the production of the retaining springs must be used and complicated forming steps must be carried out to produce the retaining springs so that the mounting body can be easily and detachably fixed relative to the mounting rail by means of the retaining springs and at the same time reliable fixing of the mounting body on the mounting rail is ensured.
