Definitions

  • the present invention relates to a holding device for a mounting frame of a recessed luminaire for mounting in a mounting opening of a ceiling or wall, according to the preamble of claim 1.
  • the invention further relates to a mounting frame equipped with several such holding devices, and to a recessed luminaire equipped with such a mounting frame.
  • a suitable holding device is, for example, made from the EP 2 893 248 B1
  • the known device comprises a straight rail with a longitudinal direction, a transverse direction, and a vertical direction, and a carriage that is adjustable along the rail in the longitudinal direction.
  • the rail has a longitudinally extending guide on each of its two longitudinal sides, opposite each other in the transverse direction, while the carriage is equipped with two complementary counter-guides that are coupled to the guides for the guided longitudinal movement of the carriage along the rail.
  • the carriage is adjustable between a holding position, an intermediate position, and an assembly position. In the holding position, the carriage is located in a first longitudinal section of the rail. In the intermediate position, the carriage is located in a second longitudinal section of the rail, opposite the first longitudinal section.
  • the carriage In the assembly position, the carriage is located in the second longitudinal section and is pivoted about a pivot axis relative to the rail.
  • the pivot axis extends parallel to the transverse direction and is defined by two cylindrical pins that project from the carriage and form part of the counter-guides. The pins engage in complementary longitudinal grooves that form part of the guides and are attached to the Rails are trained.
  • a holding device can be provided on a mounting frame that can be inserted into a mounting opening when the carriages are in the mounting position, and that is held against an opening edge surrounding the mounting opening when the carriages are moved into their holding position.
  • a recessed luminaire equipped with such a mounting frame can be attached to the wall or ceiling using this mounting frame.
  • the present invention addresses the problem of providing an improved or at least a different embodiment for such a holding device, or for a mounting frame equipped therewith, or for a recessed luminaire equipped therewith, which enables simple and reliable mounting of the recessed luminaire.
  • the invention is based on the general concept of coordinating or configuring the rail and the carriage in such a way that the pivot axis, around which the carriage can pivot relative to the rail between the intermediate position and the mounting position, extends parallel to the longitudinal direction.
  • This allows the carriage to be manually gripped laterally of the rail and pivoted around the pivot axis relative to the rail.
  • the installer With the holding device attached to the mounting frame and the mounting frame inserted into the mounting opening, the installer only needs to reach axially into the mounting opening enclosed by the mounting frame until they can reach the respective carriage laterally. This results in a shallower reach into the mounting opening compared to a conventional holding device, where the carriage pivots around a pivot axis parallel to the transverse direction. This significant reduction in the reach required to operate the carriage considerably improves the handling of the holding device, thus simplifying the installation of the recessed light fixture.
  • a “configuration” is synonymous with a “design”, so that the phrase “configured so that” is synonymous with the phrase “designed so that”.
  • the pivotability of the carriage relative to the rail about the pivot axis running parallel to the longitudinal direction is achieved in the holding device presented here by the fact that one or first guide extends from the first longitudinal section to the second longitudinal section, while the other or second guide extends only in the first longitudinal section.
  • the first guide and the first counter-guide are now configured so that the carriage can pivot about the pivot axis relative to the rail in the intermediate position.
  • the pivot axis, which runs parallel to the longitudinal direction is defined by the first guide and the first counter-guide.
  • the first guide and the first counter-guide form a pivot bearing for the carriage on the rail.
  • the second counter-guide is coupled to the second guide in the holding position and decoupled from the second guide in the intermediate position.
  • the carriage By decoupling the second counter-guide from the second guide in the intermediate position, the carriage can be pivoted about the pivot axis relative to the rail by means of the first guide and the first counter-guide, and thus adjusted between the intermediate position and the assembly position.
  • the carriage When the carriage is in the intermediate position, it can be moved longitudinally along the rail, with the second guide and the second counter-guide being coupled to improve the longitudinal guidance of this adjustment. This allows the carriage to be moved longitudinally between the holding position and the intermediate position.
  • An advantageous embodiment includes a first guide rod that is connected to the rail via a web on each longitudinal side and extends in a straight line in the longitudinal direction.
  • the web is interrupted in the second longitudinal section, such that a gap is formed between the first guide rod and the rail in this second longitudinal section.
  • the first counter-guide is configured to encompass the first guide rod by more than 180° and less than 360°, such that the first counter-guide has a gap extending continuously in the longitudinal direction. This gap is dimensioned such that the web moves into the gap when the carriage is moved longitudinally.
  • the first counter-guide penetrates the first guide rod and passes through the gap transversely to the longitudinal direction.
  • the first counter-guide is thus designed as a slotted sleeve.
  • the gap in the sleeve forms a longitudinal slot in which the web can move longitudinally to allow the carriage to move longitudinally along the rail. Since the first counter-guide engages the first guide rod, pivoting between the carriage and the rail about the pivot axis is also achieved. The pivot axis then runs coaxially to the guide rod. The gap provided in the web in the second longitudinal section allows the first counter-guide to move into the gap during pivoting, thus enabling pivoting between the carriage and the rail. Because the first counter-guide engages the first guide rod by more than 180°, preferably by at least 270°, it is held securely against loss on the first guide rod transversely to the longitudinal direction.
  • the second guide can have a second guide rod which is connected to the rail via a web on the respective longitudinal side of the rail and extends in a straight line in the longitudinal direction.
  • the second guide rod extends only in the first longitudinal section.
  • the second counter-guide surrounds the second guide rod by more than 180° and less than 360°, so that the second counter-guide also has a gap that extends continuously in the longitudinal direction and is dimensioned such that, when the carriage is moved longitudinally, the web penetrates the gap and passes through the gap transversely to the longitudinal direction.
  • the second guide and the second counter-guide are constructed almost identically to the first guide and the first counter-guide. Since the second guide rod extends only in the first longitudinal section, decoupling between the second counter-guide and the second guide rod inevitably occurs in the second longitudinal section. Guidance begins as soon as the second counter-guide is released from the second guide rod during longitudinal movement.
  • the respective gap is located in the circumferential direction of the respective counter guide, which runs around the longitudinal direction, and represents a longitudinal slot of the sleeve-shaped counter guide.
  • the rail can have an opening and a slot penetrating the rail in the transverse direction between the guides.
  • the opening is formed in the second longitudinal region, while the slot extends longitudinally from the first longitudinal region into the opening.
  • the slot transitions openly into the opening.
  • the opening is larger in the transverse direction than the slot.
  • the opening, the slot, the locking element, and the connecting web are now coordinated such that when the carriage is pivoted about the pivot axis between the intermediate position and the assembly position, the locking element is adjustable through the opening, and that when the carriage is moved longitudinally between the intermediate position and the holding position, the connecting web is longitudinally adjustable in the slot, penetrating the slot and positioning the locking element on a side of the rail facing away from the carriage.
  • the locking element guided in the slot creates an additional positive fit between the slide and the rail, improving the support between them.
  • the positioning of the locking element here is equivalent to a positive-locking hold transverse to the longitudinal direction between the slide and the rail. Slide and rail by means of the shearing element and the connecting bridge.
  • the gap of the first counter-guide can be positioned such that the first counter-guide can be attached to and removed from the first guide rod in the longitudinal direction when the locking element is moved out of the opening by pivoting the slide about the pivot axis, so that the slide can be mounted on and removed from the rail. This results in particularly simple mounting and dismounting of the slide on the rail.
  • An advantageous configuration is one in which the first counter-guide has a constriction at a longitudinal end facing away from the first longitudinal section of the rail, in the gap with respect to a circumferential direction in which the first counter-guide engages the first guide rod.
  • This constriction can be, for example, in the form of a protruding nose in the circumferential direction of the counter-guide, and it must be smaller in this circumferential direction than a web section that limits the gap between the rail and the first guide rod on a side facing away from the first longitudinal section.
  • a web section that limits the gap on a side facing away from the first longitudinal section is larger than the gap of the first counter-guide with respect to a circumferential direction in which the first counter-guide engages the first guide rod.
  • a detent contour can be formed on one of the rail and the slide, featuring several longitudinally adjacent detent steps.
  • a counter-detent contour complementary to the detent steps can be formed, which has at least one detent lug that interacts with the detent steps to maintain the relative position between the slide and the rail with respect to the longitudinal direction.
  • the detent contour with multiple longitudinally adjacent detent steps defines several longitudinal positions between the rail and the slide in which the slide is held against the rail.
  • a preferred embodiment features a detent contour formed on the rail, with detent steps located on both sides of the slot on a side of the rail facing the carriage in the holding position.
  • the counter-detent contour is formed on the carriage, with at least one such detent lug located on a side of the carriage facing the locking element.
  • the detent contour and the counter-detent contour interact to position the carriage relative to the rail by means of a positive locking action extending transversely to the longitudinal direction.
  • the locking element ensures a secure and, in particular, pre-tensioned engagement between the detent steps and the detent lugs, thereby securing the respective detent position.
  • the slide can have a pressure area.
  • the mounting bracket has a contact area that, in the holding position, projects vertically away from the rail.
  • this contact area provides stable support for the respective slide at the opening edge.
  • a particularly advantageous embodiment involves connecting the contact area to the slide via a spring, which can be elastically designed.
  • the mounting frame can be secured at the respective opening edge by clamping the opening edge between the contact areas of the mounting brackets and the mounting frame in the longitudinal direction. This simultaneously ensures a clean installation with the mounting frame fully in contact with the opening edge.
  • a mounting frame according to the invention designed for mounting a recessed luminaire in a mounting opening in a ceiling or wall framed by an opening edge, comprises a frame body with a flange for bearing against an outer surface of the opening edge facing away from the mounting opening, and several retaining devices of the type described above, which are arranged circumferentially distributed around the frame body.
  • the flange extends circumferentially around the frame body, rotating about a longitudinal center axis of the frame body.
  • the flange extends circumferentially around the frame body.
  • the respective rail can then be rigidly connected to the frame body with its longitudinal direction aligned parallel to the longitudinal center axis. This allows the carriages to be adjusted parallel to each other along the rails.
  • the mounting frame can be inserted into the mounting opening when the carriages are in their mounting position.
  • the mounting frame then has, in the area of the flange,
  • the mounting frame has its largest cross-section perpendicular to the longitudinal center axis.
  • the mounting frame rests with its flange against the outside of the opening edge and is secured to the opening edge when the slides assume their holding position and are supported against an inner surface of the opening edge facing the mounting opening.
  • the cross-section of the mounting frame in the area of the holding devices is at least larger than the cross-section of the mounting opening and preferably also larger than the cross-section in the area of the flange. This allows the mounting frame to be positively locked to the opening edge by means of the slides.
  • the opening edge is then clamped parallel to the longitudinal center axis between the flange and the slides.
  • the respective slide can be designed separately from the frame body, thus forming a separate component, and can be attached to the frame body by means of a clip or snap connection.
  • This allows the frame body and slide to be manufactured separately, for example as castings and/or from plastic.
  • an integrated design is also conceivable, in which the slides are integrally formed on the frame body.
  • the frame body can be closed in the circumferential direction.
  • the frame body's cross-section is adapted to the respective mounting opening, or vice versa.
  • a recessed luminaire according to the invention is intended for installation in a mounting opening of a ceiling or wall framed by an opening edge.

At least one light source, which may include at least one light-emitting diode, can be arranged on this light source holder.
  • the mounting frame makes it particularly easy to install the recessed luminaire in a mounting opening.
  • a detachable connection may be provided between the mounting frame and the light source holder, designed such that the mounting frame can first be installed in the mounting opening or attached to the edge of the opening without the light source holder. The light source holder can then be attached to the mounting frame, which is already fixed to the edge of the opening.
  • Such a detachable connection can be achieved, for example, by a snap-fit mechanism, a bayonet fitting, or a screw thread.
  • the recessed luminaire can have a reflector that connects the mounting frame to the light source holder.
