Definitions

  • the present invention relates to a retaining clip for a light according to the preamble of claim 1.
  • the invention also relates to a light equipped with at least one such retaining clip.
  • the lamp has a straight and elongated supporting profile, which has a profile base and two opposing profile walls which are connected to one another by the profile base and which each have a profile holding contour at their end remote from the profile base. Furthermore, the lamp has at least one linear and elongated equipment carrier, which has a carrier base and two carrier walls that lie opposite one another and are connected to one another by the carrier base, each of which has a carrier retaining contour that is complementary to the profile retaining contour. In a final assembly state of the lamp, the support holding contours interact with the profile holding contours to positively hold the device mount on the support profile.
  • the light is equipped with at least one retaining clip, which is used to set the gear tray on the support profile in the final assembly state.
  • the lamp is expediently equipped with two or more such retaining clips.
  • the respective generic retaining clip is a shaped sheet metal part that is produced from a single piece of sheet metal by forming.
  • the holding clip has at least one support hook for each support wall, with which the holding clip can be fixed to the device support or is fixed to it in the final assembly state.
  • the respective retaining clip for each profile wall has at least one profile tab, which can be supported on the profile retaining contour of the respective profile wall for the final assembly state or is supported on it in the final assembly state.
  • the retaining clip in the final assembly state the retaining clip is attached to the device carrier via its carrier hook and supported on the support profile via its profile tabs, whereby the retaining clip fixes the device carrier to the support profile and in this respect supports or secures the connection between the device carrier and the support profile.
  • the known lamp is also equipped with a holding bracket which is separate from the holding clip and which is designed as a shaped wire part and for this purpose is produced from a single piece of wire by forming.
  • This retaining clip is equipped with a profile hook for each profile wall, which can be hooked into the profile retaining contour of the respective profile wall for an intermediate assembly state or is hooked to it in this intermediate assembly state and thereby holds the device carrier on the support profile in the intermediate assembly state.
  • the equipment carrier is spaced from the support profile.
  • This retaining clip is connected to the device carrier via the retaining clip, for which purpose the retaining clip is hooked onto the retaining clip in a form-fitting manner. To do this, the formed wire part must be threaded into the formed sheet metal part in a complex manner. At the same time, this can make it difficult to handle the retaining clip to fix it to the equipment carrier.
  • the present invention deals with the problem of specifying an improved embodiment for a retaining clip of the type described above or for a lamp equipped with it, which is characterized in particular by reduced production costs and preferably by simplified handling.
  • the invention is based on the general idea of integrating the headband into the retaining clip.
  • it is proposed to equip the retaining clip for each profile wall with at least one profile hook, which can be hooked into the profile retaining contour of the respective profile wall for the intermediate assembly state or is hooked onto it in the intermediate assembly state and thereby holds the device carrier in the intermediate assembly state on the supporting profile.
  • the retaining clip is already fixed to the equipment rack.
  • the design proposed here for the retaining clip integrates the retaining function of the retaining clip into the retaining clip without requiring an additional component for this purpose.
  • the entire retaining bracket is not integrated into the retaining clip for this purpose, only the profile hooks, whereby it must also be taken into account that the profile hooks in the retaining clip according to the invention are designed as sections of the sheet metal part and not as sections of a sheet metal part, as is the case with a separate retaining bracket wire molding.
  • the retaining clip according to the invention can be handled as easily as a conventional retaining clip without a mounting bracket attached to it.
  • the complex assembly of the retaining bracket with the retaining clip is no longer necessary for the assembly of the light.
  • the production costs for the retaining clip hardly increase as a result of the profile hooks additionally provided, while the production costs for the separate retaining clip are completely eliminated.
  • the respective profile hook also has a flat cross-sectional profile parallel to the longitudinal direction of the light.
  • the support profile can be grounded even in the intermediate assembly state.
  • the supporting profile is usually painted or coated.
  • the retaining clip is usually made of stainless steel and is expediently unpainted or uncoated overall.
  • the retaining clip can have a clip base, which is supported on the carrier base when the retaining clip is attached to the equipment carrier.
  • the respective profile tab can be formed by a clip section protruding from the clip base, with the respective profile hook being formed by the same clip section following the profile tab.
  • the clip section that forms the profile tab is quasi lengthened and shaped in such a way that the respective profile hook can be formed with it.
  • the retaining clip according to the invention can thus be implemented particularly inexpensively.
  • the retaining clip is extremely compact. It is noteworthy that the respective clip section has a flat profile cross-section parallel to the longitudinal direction of the lamp both in the profile strap and in the profile hook.
  • the retaining clip can have only a single clip section for each profile wall, which is undivided or continuous in the longitudinal direction of the support profile and forms the profile tab and the profile hook. This leads to a particularly inexpensive embodiment.
  • the retaining clip can have exactly one profile bracket and/or exactly one profile hook for each profile wall. These measures also reduce the production costs.
  • At least one blade-like cutting contact is formed on the respective profile tab, which cuts into the respective profile holding contour of the support profile in the final assembly state for electrical contacting between the retaining clip and the support profile.
  • the support profile or the retaining clip can be grounded inside the lamp. It is noteworthy that this grounding occurs when the device carrier is mounted on the support profile in connection with the respective retaining clip takes place automatically and inevitably, since the respective cutting contact performs a relative movement under prestress with contact to the respective profile holding contour due to the kinematics provided.
  • the respective profile bracket is in contact with the respective profile holding contour via the respective cutting edge, so that there is a very high mechanical load on a paintwork or coating expediently provided on the support profile, which is damaged in the event of a further relative movement.
  • the cutting contact cuts through the coating or lacquer that may be provided and makes contact with the metal support profile.
  • a further development is particularly advantageous in which the respective cutting contact is formed on a tab edge which is supported on the respective profile holding contour in the final assembly state. This ensures the desired electrical contact for the final assembly state.
  • the cutting contact can be formed during the production of the retaining clip by a corresponding forming process.
  • the respective area of the edge of the tab can be angled and/or sharpened.
  • the retaining clip can also have a clip base, which is supported on the carrier base when the retaining clip is attached to the equipment carrier.
  • a transverse strap can be formed on this clip base, which is spring-elastic about a transverse direction running transversely to the longitudinal direction of the lamp. With the help of this transverse strap, additional functions can be implemented on the retaining clip.
  • the transverse strap extends parallel to the transverse direction of the lamp and is resilient in the vertical direction of the lamp.
  • the transverse strap can have a free end which opens up in a longitudinal section of the retaining clip running parallel to the longitudinal direction of the lamp the same side, namely on the upper side, as the profile tabs and outside of the clip base and forms an insertion contour for a holding portion of an attachment that can be fixed or fixed by means of the transverse strap on the retaining clip.
  • the free end protruding upwards creates a wedge-shaped insertion contour, which facilitates the insertion of the holding section.
  • the transverse tab can have a barb between the free end and the clip base, which is directed away from the free end, so that the barb interacts with the retaining section to fix the attachment to the retaining clip and in particular claws it. This makes it more difficult for the retaining section to be pulled out counter to the direction of insertion, which improves the attachment of the attachment to the retaining clip.
  • the transverse strap can have an S-shaped profile in the longitudinal direction of the lamp.
  • the transverse strap can have a free end in the longitudinal direction, which is spaced apart from the clip base in the vertical direction.
  • the transverse tab allows a component or the add-on part or a component section or the holding section to be inserted in the longitudinal direction on an upper side of the device carrier facing the support profile.
  • the transverse strap presses the component inserted therein or the component section inserted therein against the carrier base and thereby creates an efficient holding effect.
  • the transverse strap can have at least one barb which, when a component or component section is inserted into the transverse strap, hooks onto the component or component section and makes it difficult to pull the component or component section out of the transverse strap. This improves the holding effect.
  • the respective component fastened to the device carrier with the retaining clip can also be grounded.
  • an add-on part can be fixed to the retaining clip and thus via the retaining clip to the equipment carrier by means of the transverse strap.
  • a holding part can be, for example, a control device or a transformer or power electronics or the like for one or more electrical loads that can be attached to the equipment carrier.
  • the carrier walls of the device carrier can have opposite slots on the inner side facing one another.
  • the retaining clip it can now be matched to the slots in such a way that the carrier hooks engage in these slots when the retaining clip is mounted on the equipment carrier.
  • the retaining clip is fixed to the support walls in the longitudinal direction by positive locking.
  • At least one sharp-edged contact tip is formed on the carrier hook, which penetrates into the respective carrier wall for electrical contacting between the retaining clip and the device carrier.
  • the contact points between the respective inner wall and the respective carrier holding contour can penetrate into the respective carrier wall.
  • the electrical contacting takes place more or less in the interior of the equipment carrier or in an equipment carrier interior space that is separated from a holding profile interior space.
  • the respective profile wall has an exposed, unpainted end edge on the respective profile holding contour.
  • the respective profile hook can now be matched to the respective profile retaining contour be that the respective profile hook is supported in the intermediate assembly state under tension at the respective end edge.
  • electrical contact can also be made between the support profile and the retaining clip for the intermediate assembly state, which means that the support profile or the retaining clip can be grounded in particular for the intermediate assembly state. This is particularly advantageous if the electrical consumer or consumers of the equipment carrier is or are already connected to a power supply during installation. This can already be the case when the lamp is installed for the first time.
  • a luminaire according to the invention which is particularly suitable for a light strip having several such luminaires, is equipped with a supporting profile that is straight and elongated with respect to the longitudinal direction of the luminaire, which has a profile base and two profile walls that are opposite one another and are connected to one another by the profile base Profile floor distant ends each have a profile holding contour.
