Definitions

  • the invention relates to a retaining spring for fixing a mounting body of a light on a mounting rail of the light according to the preamble of claim 1 and an arrangement comprising retaining spring, mounting rail and mounting body.
  • 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 to 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 with circuit boards LEDs and control gear.
  • the mounting rail is usually first attached to the component and then the mounting body, which is equipped with the aforementioned electrical 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 lamp are arranged, for example circuit boards, operating devices, etc.
  • the mounting rail and mounting body are each designed to be elongated in a longitudinal direction.
  • the mounting rail usually has a cross section perpendicular to Longitudinal direction, which is open along a vertical direction at a vertical end and is delimited along a transverse direction by two side walls which are connected to one another by a bottom portion of the support rail running along the transverse direction.
  • the support rail is usually attached to a component via its base section.
  • 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 base section extending in the transverse direction and side walls extending vertically away from the base section on the two transverse sides of the base section.
  • the side walls each form a fastening projection, wherein the base section of the retaining spring can be pressed against the base section of the installation body via the fastening projections of the assembly body and can thereby be fixed to the assembly body.
  • the base section of the mounting body is preferably arranged at the open end of the support rail.
  • Retaining springs of the generic type are used to enable the mounting body to be fixed on the mounting rail as simply as possible and at the same time as robustly as possible, and also to enable the mounting body to be easily dismantled from the mounting rail. Because for maintenance purposes it is necessary that the assembly body from the mounting rail can be removed 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 a base section for mounting on the assembly body and which each have a holding section extending vertically away from the base section at both transverse ends of the base section and on which a holding projection extending outward in the transverse direction is provided .
  • a holding projection is provided on each of the two holding sections opposite each other in the transverse direction, the holding projection 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. This sheet metal part is then fixed to the assembly body with the base section.
  • the support rail usually has a fastening projection on each of its side walls which, starting from the side wall, which extends vertically, extends in the transverse direction.
  • the fastening projections are often designed in such a way that the fastening projection of one side wall extends in the transverse direction towards the respective opposite side wall.
  • the holding sections each have a connection to the base section that is resilient in the transverse direction, so that the holding sections can be deflected in the transverse direction when they are inserted past the fastening projection into the support rail, the holding projections of the holding sections after vertically passing the fastening projections on the side walls of the support rail snap into place behind these fastening projections, whereby the assembly body is fixed to the mounting rail.
  • this makes it possible to easily mount the mounting body on the mounting rail.
  • the vertical force acting on the mounting body relative to the mounting rail causes the retaining projection, in particular resiliently, to be deflected along the transverse direction, which reduces its overlap with the fastening projection of the mounting rail in the transverse direction.
  • the transverse overlap between the fastening projection and the holding projection is, however, essential for a reliable fixation of the mounting body on the mounting rail.
  • the holding projection can easily slide off the fastening projection in the transverse direction and the Mounting body detaches from the mounting rail.
  • the production and assembly of the retaining springs on the assembly body involve a not inconsiderable amount of effort.
  • retaining springs of the generic type due to the various requirements that they have to meet, have so far only either been designed in a complicated manner and made in one piece, which leads to high manufacturing costs, or are made in several parts, which leads to high assembly costs.
  • DE4300549A1 a retaining spring comprising a base section and retaining sections for fixing a mounting body on a mounting rail, which additionally provides a fastening for a reflector.
  • DE102013020510B3 , DE6926006U and DE2022009A1 Retaining springs which have rigid retaining sections which are slidably connected to one another via a separately designed spring device.

  • the two holding sections of the holding spring are thus spaced apart from one another in the transverse direction, the bottom section extending in the transverse direction between the two holding sections. This spacing enables the holding sections to be moved towards one another in a resilient manner along the transverse direction.
  • the retaining sections opposite one another in the transverse direction are movable relative to one another in the transverse direction, starting from an initial position against a spring device acting in the transverse direction.
  • the spring device In the starting position, the spring device thus connects the two holding sections in the transverse direction in such a way that the spring device when the two holding sections move towards one another along the transverse direction, a restoring force exerts on the two holding sections.
  • An external force in the transverse direction is thus required in order to move the holding sections towards one another starting from the starting position, the holding sections being moved back into their starting position by the spring device after the force has been lifted.
  • the initial length can also be referred to as the rest position.

  • a corresponding guide can be provided between the second holding element and the base element, which is in particular designed identically to the guide between the base element and the first holding element.
  • an overall guide can be formed by an upper side section of the assembly body and the second guide, which is formed between the base element and the second holding element.

At least the height guide is preferably designed to limit a vertical relative movement of a transverse section of the holding element relative to a transverse section of the base element.
  • the transversal displacement path over which the height guidance is ensured is particularly preferably less than the transversal displacement path over which the lateral guidance is ensured. Because since the retaining spring is properly mounted in the assembly position on an upper side of an assembly body, the height guide only needs to ensure stable guidance of the retaining element and base element with respect to one another in the starting position in which the retaining spring can be transported independently of the assembly body and can be attached to the assembly body , since the retaining spring is usually mounted along the vertical direction on a vertical upper side of a mounting body, so that in the mounting position the mounting body can provide an additional height guide.
  • the mounting body is usually not designed in such a way that it defines a longitudinal section on its upper side, on which the base element and / or holding element are guided, which is why the transverse displacement path, via which the lateral guidance is ensured, is particularly preferably greater than the transverse displacement path , over which the height guidance is guaranteed.

  • the provision of such a transverse path limitation is particularly advantageous for the mountability of the retaining spring, since it allows the base element and retaining element to be kept stable to one another in the starting position and the starting position can be clearly defined, which can be particularly advantageous for a clear definition of lateral guidance and height guidance.
  • the base element and the holding element are held together via the guide in the starting position. In the starting position, the holding element and the base element are particularly preferably fixed to one another in a captive manner via the guide.
