Definitions

  • the invention relates to a retaining spring for fixing a mounting body of a lamp to a mounting rail of the lamp according to the preamble of claim 1 and an arrangement comprising mounting spring, mounting rail and mounting body.
  • Generic retaining springs are used to implement lights that have a mounting body and a mounting rail.
  • the mounting rail is typically used to fix the lamp to a component, for example a ceiling, various components of the lamp being arranged in the mounting rail, for example electrical cables, operating devices, radio modules, etc. Components of the lamp, for example circuit boards, are usually fastened to the mounting body LEDs and control gear.
  • the mounting rail is usually first attached to the component and then the mounting body, which is equipped with the electrical components of the lamp mentioned, fixed to the mounting rail, so that the mounting rail and mounting body form an interior in which essential elements of the lamp are arranged, for example circuit boards, operating devices, etc.
  • the mounting rail and mounting body are each 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 section of the mounting rail running along the transverse direction.
  • the mounting rail is usually fastened to a component via its base section.
  • the mounting body is usually arranged on the open vertical end of the mounting rail, so that the mounting body, together with the mounting rail, forms an interior space which is circumferentially closed by the mounting rail and mounting body perpendicular to the longitudinal direction.
  • the enclosure of the interior which is formed by the mounting 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 bottom section extending in the transverse direction and, on the two transverse sides of the bottom section, starting from the bottom section, vertically extending side walls.
  • the side walls preferably each form a fastening projection, wherein the retaining spring can be pressed with its bottom section against the bottom section of the mounting body via the fastening projections of the mounting body and can thereby be fixed to the mounting body.
  • the base section of the mounting body is preferably arranged at the open end of the mounting rail.
  • Generic retaining springs serve 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, moreover, to enable the mounting body to be easily removed from the mounting rail. Because for maintenance purposes, it is necessary that the mounting body from the mounting rail can be removed so that a technician has access to the interior and can replace, for example, lamps, circuit boards or the like.
  • the mounting rail usually has a fastening projection on each of its side walls, which extends from the side wall, which extends vertically, in the transverse direction.
  • the fastening projections are often designed such that the fastening projection of one side wall extends in the transverse direction towards the respectively opposite side wall.
  • the vertical force acting on the mounting body relative to the mounting rail causes the holding projection, in particular spring-elastic, to be deflected along the transverse direction, as a result of which its overlap in the transverse direction with the fastening projection of the mounting rail is reduced.
  • the transverse overlap between the fastening projection and the holding projection is essential for reliably fixing the mounting body to the mounting rail. If the overlap is reduced, it can easily occur that the holding projection slides in the transverse direction from the fastening projection and the Detaches mounting body from the mounting rail.
  • the manufacture and assembly of the retaining springs on the assembly body involve a not inconsiderable effort. It should be taken into account that such generic retaining springs have so far either only been of complex design and manufactured in one piece due to the various requirements that they have to meet, which leads to high manufacturing costs, or are made in several parts, which leads to high assembly costs.
  • the present invention has for its object to provide a retaining spring that at least partially eliminates at least one of the above-described problems of generic retaining springs.
  • the invention proposes a retaining spring which has a bottom section for mounting on the mounting body and on both transverse ends of the bottom section a holding section which extends vertically away from the bottom section and on which a holding projection extending in the transverse direction is provided ,
  • the two holding sections of the holding spring are thus spaced apart from one another in the transverse direction, the bottom section extending between the two holding sections in the transverse direction. This spacing enables the holding sections to be moved resiliently towards one another along the transverse direction.
  • the holding sections lying 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 such that the spring device when the two holding sections move towards one another, exerts a restoring force on the two holding sections along the transverse direction.
  • An external force in the transverse direction is therefore required in order to move the holding sections towards one another from the starting position, the holding sections being moved back into their starting position by the spring device after the force has been released.
  • the starting length can also be called the rest position.
  • the retaining spring In the initial position or in the rest position, in one embodiment the direction of the spring range, according to the invention the retaining spring has two separate elements.
  • a first element of the two separate elements is designed as a base element which forms the bottom section and thus has the bottom section.
  • a second element of the two separate elements is designed as a holding element, which forms a first of the two holding sections and thus has a first of the two holding sections of the holding spring.
  • the second holding section is integrated in the base element, in another embodiment it is formed by a further holding element.
  • the holding spring thus has three separate elements, namely a first holding element which forms the first holding section, a second holding element which forms the second holding section and the base element which forms the bottom section.
  • the first and second holding sections are the above-mentioned holding sections of the holding spring, which are spaced apart in the transverse direction.
  • the spring device presses the holding element and the base element with a spring force against a respective stop, for example by pressing a section of the holding element against a section of the base element, in another embodiment the holding element and base element are in the starting position respectively. The rest position is not acted upon by a spring force exerted by the spring device.
  • the holding element is guided so as to be displaceable relative to the base element along the transverse direction.
  • the holding element has the holding projection of the first holding section.
  • the holding element is displaceably guided relative to the base element by means of a guide along the transverse direction.
  • the guidance is preferably formed by mutually corresponding sections of the holding element and the base element.
  • the holding element is particularly preferably guided so as to be linearly displaceable relative to the base element by means of the guide in the transverse direction.
  • a guide which acts between the base element and the holding element, and by means of which the holding element is guided relative to the base element starting from the starting position via a displacement path along the transverse direction, ensures that the holding projections of the two holding sections lying opposite one another in the transverse direction start from the starting position can be moved towards each other along the transverse direction, while the guide ensures that the base element and holding element are securely guided to each other.
  • the retaining spring can be produced in a simple manner and assembled in a simple manner, since the guide ensures variable adjustment of the transverse distance between the retaining projections, while the base element and retaining element are held relative to one another via the guide, so that after assembly of the Retaining spring on a mounting body the mounting body can be easily locked with a mounting rail.
  • the guide particularly preferably forms part of an overall guide in an assembly position, ie in a state in which the base section is mounted on the assembly body, the assembly body forming a further part of the overall guide and Base element and holding element in the overall guidance have a determined freedom of movement with respect to one another that is limited in all directions.
  • the mounting body has an upper side on which the bottom section is mounted in a fixed position in the mounting position, the overall guide being formed by a section of the top side of the mounting body on which the bottom section is mounted and the guide, the guide being in particular one to the other Corresponding sections of the base element and holding element is formed, so that a three-dimensional space is defined in the assembly position by the guide, that is to say in particular by the mutually corresponding sections of the base element and holding element and the aforementioned section of the top of the mounting body, within which one relative movement of the base element and holding element to each other is made possible and by which this relative movement is limited.
  • a corresponding guide can be provided between the second holding element and the base element, which is in particular identical to the guide between the base element and the first holding element.
  • an overall guide as explained in the assembly position, can be formed by a top section of the assembly body and the second guide, which is formed between the base element and the second holding element.
  • the guide comprises a side guide, by means of which the holding element is guided continuously relative to the base element starting from the starting position over a transverse displacement path and which is designed to prevent the holding element from rotating relative to the base element about the vertical direction.
  • the side guide is particularly preferably designed to restrict rotation of the holding element relative to the base element by the vertical direction over a rotation angle of less than 10 °, in particular less than 5 °.
  • the side guide preferably ensures the described prevention of rotation of the holding element relative to the base element over the entire transverse displacement path.
  • the side guide particularly preferably comprises a rail which is formed by the base element or holding element, preferably is formed by the base element, the other of the two elements having a section guided in the rail, the rail extending at least over the length of the displacement path.
  • the base element particularly preferably engages around the longitudinal side of the holding element at two opposite longitudinal ends of the holding element, so that the longitudinal position of the holding element is fixed by the base element.
  • the base element particularly preferably forms two side walls running along the transverse direction, which are spaced apart in the longitudinal direction and between which the base element is arranged, the side walls and the section of the holding element located between the side walls forming the side guide.
  • the base element or the holding element has a slot running along the transverse direction, a section of the other of the two elements being guided in this slot and the length of the slot determining the length of the side guide.
  • the side guide across the transverse displacement path, wherein the transverse displacement path has a length in the transverse direction of in particular at least 3 mm, favors the stability of the guide considerably and thus ensures that the retaining spring can be mounted as easily as possible on a mounting body.
  • the side guide is preferably formed by mutually corresponding sections of the base element and the holding element, which overlap with a planar extent that extends perpendicular to the transverse direction.
  • the guide has a height guide, by means of which the holding element is guided relative to the base element in the starting position and which is designed to prevent rotation of the holding element relative to the base element by a longitudinal direction running perpendicular to the vertical direction and perpendicular to the transverse direction.
  • the height guide is thus particularly preferably designed such that it limits a rotation of the holding element relative to the base element by less than 30 °, in particular less than 20 °, in the longitudinal direction.
  • the height guide is particularly preferably designed such that it also limits a rotation of the base element relative to the holding element about the transverse direction to less than 30 °, in particular less than 20 °.
  • the height guide can preferably be formed by mutually corresponding sections of the base element and the holding element.
  • the height guide is preferably designed, at least in the Starting position, in particular over a transverse displacement path guaranteed by the height guide, to limit a vertical relative movement of at least a section of the base element and of at least a section of the holding element to one another. 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 transverse displacement path by means of which the height guidance is ensured, is particularly preferably less than the transverse displacement path, by means of which the lateral guidance is ensured. Because in the assembly position the retaining spring is mounted on the top of a mounting body as intended, the height guide only has to ensure stable guidance of the retaining element and base element to one another in the starting position, in which the retaining spring can be transported independently of the mounting body and can be attached to the mounting body , since the retaining spring is usually mounted on a vertical upper side of a mounting body along the vertical direction, so that the mounting body can provide additional height guidance in the mounting position.
  • 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 larger than the transverse displacement path , through which the height guidance is guaranteed.
  • the base element engages around the holding element on two longitudinally opposite longitudinal ends of the holding element on the longitudinal side and on two opposite vertical ends of the holding element on the vertical side, with the base element particularly preferably covering the entire element transversal displacement path, by means of which the lateral guidance is guaranteed, encompasses the long sides at its two longitudinal ends and, in addition, continuously overlaps on at least one vertical side of the holding element over the entire transverse displacement path, by means of which the lateral guidance is ensured.
  • the height guide has a rear grip section formed by the holding element, which in the starting position is in a rear grip position in which it grips vertically behind an assigned section of the base element and overlaps with it over a surface that runs perpendicular to the vertical direction.
  • the rear grip section extends from a section of the holding element, which is located on a vertical side of the base element and overlaps with the base element on this side, to the opposite side of the base element and overlaps with the base element on this opposite vertical side.
  • the base element and the holding element are designed to be brought together via an exclusively linear movement, in particular linear movement in the transverse direction, in order to reach the starting position, the rear grip section being able to be brought into the rear grip position by this linear movement of the base element and holding element.
  • the base element and the holding element are particularly preferably movable via a linear movement in a direction in which they are guided linearly via the lateral guide, the rear grip section being able to be brought into its rear grip position by exercising this linear movement.
  • the design of the base element and the holding element in such a way that they can be brought together by means of an exclusively linear movement in order to reach the starting position and thus to implement the holding spring is particularly advantageous for the manufacturing process of the holding spring.
  • the base element and / or holding element have run-on bevels, so that by specifying an external, linear movement of the holding element and base element relative to one another, the holding element and the base element can be brought into their starting position, the run-up bevels determining the movement of the holding element and base element with respect to one another when they are pushed towards each other by a purely linear movement.
  • the rear grip section and the assigned section of the base element are each designed in the manner of a U-hook, the open end of which is a transverse end, the closed ends of the two U-hooks being opposite one another in the transverse direction.
  • the spring device can contribute to ensuring the height guidance.
  • the spring device can be fixed to the base element and can be guided with a section in a vertical guide of the holding element, which determines the vertical position of the section of the spring device. It is also possible that the spring device is fixed to the holding element and is guided in the starting position with a section in a vertical guide provided by the base element, which defines the vertical position of the section of the spring device in the starting position.
  • the guide preferably has a transverse path limitation, which is formed by mutually corresponding stops of the base element and the holding element, wherein in the starting position the spring device presses the stops of the base element and the holding element against one another, in particular against one another in the transverse direction.
  • a transverse path limitation is particularly advantageous for the mountability of the retaining spring, since in this way the base element and retaining element can be kept stable in relation 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 by the guide in the starting position.
  • Holding element and base element in the starting position are thus particularly preferably fixed to one another in a captive manner via the guide.
  • the base element and holding element in the starting position are particularly preferably not detachable from one another in a non-destructive manner, but only after the base element and holding element have been deflected relative to one another, starting from the starting position in the transverse direction, with the deflection of the holding projections of the two holding sections being moved toward one another.
  • the base element and the holding element can preferably only be detached from one another in a non-destructive manner after they have been moved toward one another in the transverse direction from the starting position, in particular have been moved towards one another via a larger transverse displacement path than the distance of the transverse displacement path, through which height guidance and lateral guidance are simultaneously ensured are.
  • the holding projection has a contact surface for vertical contact with a fastening projection, ie for contacting a vertical side of the fastening projection, with a mounting rail, the contact surface in particular extending obliquely vertically upward toward the transverse end of the holding projection.

  • the retaining spring particularly preferably has a catch hook on each of the transversely opposite end regions, which projects vertically over the retaining sections, in particular over the retaining projections of the retaining sections, and which is transverse in a position of the retaining sections in which they are moved transversely towards one another from the starting position protrudes beyond the associated holding section.

  • the catch hook protrudes transversely in the initial position via the holding section assigned to it.
  • the catch hook can be formed, for example, by the base element or by the holding element.
  • the catch hook ensures that even if an extraordinarily high force acts between the mounting body and the mounting rail, the retaining spring can prevent the mounting body from completely detaching from the mounting rail when it is attached to its base section the mounting body is attached. Because the protrusion of the catch hook vertically over the holding section and transversely over the holding section ensures that in a state of the holding spring in which the base element and holding element have moved towards one another due to a considerable development of force, the catch hook can still hold on a fastening projection of a mounting rail, after the retaining projections of the retaining spring have slipped on the corresponding fastening projections of the mounting rail due to the action of force.
