Description

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. Typically, 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. When assembling a lamp, 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. Typically, 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. At least in some longitudinal sections, 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. Preferably, 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. In an operating position, 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. For this purpose, 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 . In other words, 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. Such 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. In particular, 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. When the mounting body is mounted on the mounting rail, the mounting body is thus moved vertically towards the mounting rail. 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. In principle, this makes it possible to easily mount the mounting body on the mounting rail. However, it has turned out to be problematic that such a fixation, as can be provided by the generic retaining springs, cannot withstand a high vertical force load that acts relatively between the support rail and the mounting body. 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 found in ceilings in Buildings with jerky loading of the ceilings can occur, 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. Due to the resilient design of generic retaining springs, however, generic retaining springs are designed precisely so that their retaining sections can be bent in a resilient manner relative to the base section in the transverse direction. With a corresponding force load, 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. When the overlap is reduced, the holding projection can easily slide off the fastening projection in the transverse direction and the Mounting body detaches from the mounting rail. In addition, in the case of retaining springs of the generic type, the production and assembly of the retaining springs on the assembly body involve a not inconsiderable amount of effort. It must be taken into account that such 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. For example disclosed 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. Continue to concern 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 present invention is based on the object of providing a retaining spring which at least partially eliminates at least one of the above-described problems of retaining springs of the generic type.

As a solution to the above-mentioned object according to the invention, the invention proposes a retaining spring which has a base section for mounting on the assembly body and at both transverse ends of the base section each having a holding section extending vertically away from the base section, 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 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. In the The retaining spring according to the invention, 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. 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. In the starting position or rest position, the spring direction can in one embodiment. 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. In one embodiment, the second holding section is integrated in the base element, in another embodiment it is formed by a further holding element. In the last-mentioned embodiment, the retaining spring thus has three separate elements, namely a first retaining element which forms the first retaining section, a second retaining element which forms the second retaining section and the base element which forms the bottom section. The first and second holding sections are the holding sections of the holding spring explained above, which are spaced apart from one another in the transverse direction. In one embodiment, the spring device presses the holding element and the base element with a spring force against a respective stop in the starting position or rest position, 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 or.

The rest position is not acted upon by a spring force exerted by the spring device. According to the invention, the holding element is guided displaceably relative to the base element along the transverse direction. The holding element has the holding projection of the first holding section. In one embodiment, the holding element is guided displaceably relative to the base element by means of a guide along the transverse direction. In general, the guide is preferably formed by mutually corresponding sections of the holding element and the base element. Particularly preferably, the holding element is guided so as to be linearly displaceable in the transverse direction relative to the base element by means of the guide. The provision of a guide which acts between the base element and the holding element and via which the holding element is guided relative to the base element, starting from the starting position over 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, starting from the starting position can be moved towards one another along the transverse direction, while the guide ensures that the base element and holding element are securely guided towards one another. Accordingly, thanks to the configuration according to the invention, the retaining spring can be produced in a simple manner and assembled in a simple manner, since the guide ensures a variable setting 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 the Retaining spring on a mounting body, the mounting body can be locked in a simple manner with a mounting rail. Particularly preferably, the guide 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 The base element and the holding element in the overall guide have a determined, limited freedom of movement in all directions. Particularly preferably, the mounting body has a top on which the bottom section is fixed in position in the mounting position, the overall guide being formed by a section of the top of the mounting body on which the bottom section is mounted, and the guide, the guides being in particular through each other Corresponding sections of the base element and holding element is formed, so that in the assembly position by the guide, ie in particular by the mutually corresponding sections of the base element and holding element forming the guide, and the said section of the top of the assembly body, a three-dimensional space is defined within which a relative movement of the base element and holding element to one another is enabled and by which this relative movement is limited. Correspondingly, this can also be provided when two holding elements are provided, ie 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. Correspondingly, as explained in the assembly position, 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. The advantageous embodiments described below with reference to the guide between the base element and the holding element can be applied analogously to embodiments in which two holding elements are provided, in which a correspondingly designed first guide is designed between the base element and the first holding element and a correspondingly designed second guide between the base element and second holding element is formed.

In one embodiment, the guide comprises a lateral 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 rotation of the holding element relative to the base element about the vertical direction. The lateral guide is particularly preferably designed to restrict a rotation of the holding element relative to the base element about the vertical direction over a rotation angle of less than 10 °, in particular less than 5 °. The lateral guide preferably ensures the described prevention of a rotation of the holding element with respect 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 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 holding element on two opposite longitudinal ends of the holding element on the longitudinal side, so that the longitudinal position of the holding element is determined by the base element. Particularly preferably, the base element forms two side walls running along the transverse direction, which are spaced apart from one another in the longitudinal direction and between which the base element is arranged, the side walls and the portion of the holding element located between the side walls forming the side guide. In one embodiment, 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 lateral guide. The provision of the lateral guide over the transversal displacement path, wherein the transverse displacement path has a length in the transverse direction of in particular at least 3 mm, aids the stability of the guide considerably and thus ensures that the retaining spring can be mounted on an assembly body as easily as possible. In general, the lateral guide is preferably formed by mutually corresponding sections of the base element and the holding element, which overlap with a flat extension that extends perpendicular to the transverse direction.

In one embodiment, 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 the holding element from rotating relative to the base element about a longitudinal direction perpendicular to the vertical direction and perpendicular to the transverse direction. The height guide is particularly preferably designed in such a way that it limits a rotation of the holding element relative to the base element about the longitudinal direction to less than 30 °, in particular less than 20 °. The height guide is particularly preferably designed in such a way 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. Particularly preferably, mutually corresponding sections of the base element and the holding element can be provided, which contribute both to lateral guidance and to vertical guidance. Particularly preferably, the mutually corresponding sections of the base element and the holding element, which form the height guide, overlap flat with a flat extension that runs perpendicular to the vertical direction. In general, the height guide is preferably designed, at least in the Starting position, in particular over a transverse displacement path ensured by the height guide, to limit a vertical relative movement of at least one section of the base element and of at least one 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 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. In contrast to this, 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. In a particularly preferred embodiment, the base element engages around the holding element in the starting position at two longitudinally opposite longitudinal ends of the holding element on the longitudinal side and at two opposite vertical ends of the holding element on the vertical side, the base element particularly preferably over the entire holding element transversal displacement path, over which the lateral guide is ensured, encompasses the longitudinal side at its two longitudinal ends and furthermore continuously overlaps over the entire transverse displacement path, over which the lateral guide is ensured, on at least one vertical side of the holding element. Particularly preferably, the height guide has a rear grip section formed by the holding element, which is in the starting position in a rear grip position in which it vertically engages behind an assigned section of the base element and overlaps it over a surface perpendicular to the vertical direction. Particularly preferably, 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. In one embodiment, 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 engagement section being able to be brought into the rear engagement position by this linear movement of the base element and the holding element with respect to one another. Particularly preferably, the base element and the holding element can be moved via a linear movement in a direction in which they are linearly guided over the lateral guide, the rear engagement section being able to be brought into its rear engagement 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 via an exclusively linear movement in order to reach the starting position and thus to implement the holding spring is particularly advantageous, in particular, for the production process of the holding spring.

Particularly preferably, the base element and / or the holding element have run-on bevels, so that by specifying an external, linear movement of the holding element and the base element to one another, the holding element and the base element can be brought into their starting position, the run-on bevels determining the movement of the holding element and the base element to one another when they be pushed towards each other by a purely linear movement. In one embodiment, the engagement section and the associated 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 provision of such U-hooks can ensure a particularly stable fixation of the base element and the holding element to one another and also ensure a stop between the base element and the holding element, on which the base element and the holding element rest against one another in the starting position, while the spring device creates a relative spring force between the base element and the holding element exercises. In one embodiment, the spring device can contribute to ensuring the height guidance. For example, the spring device can be fixed on the base element and 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 for the spring device to be fixed on the holding element and, in the starting position, to be guided 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.

In general, the guide has a transverse path limitation which is formed by mutually corresponding stops on the base element and 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 presses against one another in the transverse direction. 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. In one embodiment, 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. In the starting position, the base element and the holding element are particularly preferably not detachable from one another without being destroyed, but rather only after the base element and the holding element have been deflected from the starting position in the transverse direction, with the holding projections of the two holding sections being moved towards one another through this deflection. Thus, 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 towards one another from the starting position in the transverse direction, in particular have been moved towards one another over a larger transverse displacement path than the distance of the transverse displacement path, over which vertical guidance and lateral guidance are ensured at the same time are.

In one embodiment, the holding projection has a contact surface for vertical contact with a fastening projection, ie for contact with a vertical side of the fastening projection, of a support rail, the contact surface in particular extending obliquely vertically upwards towards the transverse end of the holding projection. The provision of the contact surface is special advantageous for ensuring reliable fixation of the mounting body on the mounting rail when the bottom section of the retaining spring is fixed to the mounting body and the contact surface rests against the fastening projection of the mounting rail, the contact surface naturally extending perpendicular to the vertical. By providing a contact surface which extends obliquely vertically upwards towards the transverse end of the retaining projection, ie extends vertically away from the base section, a vertical pressing force of the mounting body towards the support rail can be ensured when the retaining spring is attached to the mounting body with its base section and the contact surface is arranged vertically above the fastening projection of the mounting rail.

Particularly preferably, the retaining spring has a catch hook on each of the two transversely opposite end regions, which protrudes vertically over the retaining sections, in particular the retaining projections of the retaining sections, and which transversely extends in a position of the retaining sections in which they are moved transversely towards each other from the starting position protrudes over the holding section assigned to it. Thus, a catch hook is preferably provided on each transverse end region of the retaining spring, which hook protrudes over the retaining section assigned to it, which is provided on the same transverse end of the retaining spring. Particularly preferably, the catch hook already projects transversely over the holding section assigned to it in the starting position. The catch hook can be formed, for example, by the base element or by the holding element. The catch hook ensures that even when an extraordinarily high force acts between the mounting body and the mounting rail, the retaining spring can prevent the mounting body from being completely detached from the mounting rail when its base section hits is attached to the mounting body. Because the projecting 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 slid off the corresponding fastening projections of the support rail due to the action of force.

Particularly preferably, the holding projection has on its upper side a bevel running upwards from a transverse end to the transverse center of the holding spring. This particularly advantageously simplifies the use of the retaining spring according to the invention for attaching a mounting body to a mounting rail, since as a result the retaining projection, after the bottom section has been attached to the mounting body, can simply be guided past a mounting projection of a mounting rail when the mounting body is up along the vertical direction the mounting rail is moved closed and the retaining spring is arranged on the vertical top of the mounting body, which faces the mounting rail.

In one embodiment, the retaining spring has a holder for retaining operating elements, in particular electrical lines, in a transverse region around its transverse center. The holder has two holding legs, which each run transversely from the outside to the transverse center, wherein in the starting position the holding legs are opposite one another in the transverse direction and are spaced from one another at their ends facing one another in the transverse direction or lie loosely against one another. Starting from the starting position below, the retaining legs are particularly preferred Enlargement of a distance between their ends facing one another in the transverse direction can be elastically deflected. In the starting position, the holding legs can, for example, transversely overlap with their ends facing one another in the transverse direction and be vertically spaced from one another or be spaced from one another in the transverse direction with their ends facing one another in the transverse direction. The holding legs can, however, also be designed in such a way that their transverse ends bear against one another, in particular over a section extending in the transverse direction. The elastic deflectability of the retaining legs and the enlargement of their distance starting from the starting position, either to produce a distance when they are in contact with one another in the starting position, or to increase the distance when they are already spaced apart from each other in the starting position, enables a simple introduction of the operating elements between the holding legs, so that the operating elements can be guided between the holding legs after they have been inserted between the holding legs. In the starting position, the holding legs are particularly preferably spaced apart from one another at their opposite ends by a distance of at least 1 mm. Particularly preferably, the holding legs have run-on bevels at their opposite ends, in which their extension along the longitudinal direction increases outwardly along the transverse direction starting from their respective end opposite the other leg.

In one embodiment, the holding element has a holding lug offset vertically from its holding projection towards the bottom section. By providing a holding lug arranged vertically offset from the holding projection, the holding element thus forms a receptacle for the fastening projection of the support rail, so that the Fastening projection of the support rail can be arranged vertically below the retaining projection and vertically above the retaining lug. The configuration according to the invention has significant advantages compared to retaining springs of the generic type. The guide provided between the base element and the holding element, which enables the holding element to move relative to the base element along the transverse direction, enables the mounting body to be fixed easily and detachably to the support rail with the aid of the holding spring according to the invention. As already explained with regard to retaining springs of the generic type, the spring device is designed and arranged relative to the two retaining sections in such a way that when the retaining sections are deflected in the transverse direction to one another, starting from the starting position, the deflection being effected by a movement of the retaining element relative to the base element, the spring device a spring force acting in the transverse direction exerts between the two holding sections, which acts to ensure that the holding sections return to their starting position relative to one another. In addition, the provision of the retaining lug, which is arranged vertically offset from the retaining projection, makes it possible for the retaining lug to come to rest against a section formed by the mounting rail or mounting body in the event of an acute high vertical force load between the mounting body and the mounting rail, and thereby a movement of the retaining projection relative to the fastening projection effectively limited along the transverse direction. Accordingly, the retaining lug ensures that the overlap between the fastening projection and the retaining projection in the transverse direction remains so large, even with high vertical force loads between the mounting body and the mounting rail, that the retaining spring and thus the mounting body remain reliably fixed on the mounting rail. It is particularly preferable for the retaining lug and the retaining projection to overlap along the transverse direction, but they are vertically offset from one another as explained. Particularly preferably, the retaining lug and retaining projection are connected to one another via a section of the retaining element running in the vertical direction and overlap each other perpendicular to the vertical direction. Particularly preferably, the section of the holding element which connects the holding lug and holding projection to one another runs parallel to the vertical direction. The section is particularly preferably designed as a flat sheet metal section which runs parallel to the vertical direction, the retaining lug and retaining projection being arranged directly on the flat sheet metal section. This makes it possible to achieve a particularly high level of rigidity for the retaining spring, which enables the retaining lug to come into contact with the mounting rail or mounting body without any noteworthy spring property between the retaining lug and the retaining spring, thereby preventing undesired displacement of the retaining projection relative to the fastening projection along the transverse direction. Particularly preferably, the retaining lug and retaining projection of the retaining element are vertically spaced apart from one another by less than 15 mm, in particular by less than 10 mm, in particular by less than 7 mm. As a result, the stiffness of the retaining spring and the reliability of fixing the mounting body and support rail to one another by the retaining spring according to the invention can be further enhanced. The base element and the holding element are particularly preferably each produced from sheet metal by forming. In this way, on the one hand, a particularly cost-effective production of the retaining spring is made possible, and on the other hand, thanks to the configuration of the retaining spring according to the invention, a sufficiently robust configuration of the retaining spring can be implemented. The retaining lug of the retaining element is particularly preferably formed by at least one sheet metal section protruding transversely from a vertically extending section of the retaining element.

This vertically extending section of the holding element is particularly preferably the section of the holding element that runs in the vertical direction and that connects the holding projection and holding lug to one another. Particularly preferably, the sheet metal section is arranged laterally in the longitudinal direction on the vertically extending section of the holding element and shaped by reshaping around an axis that is parallel to the vertical direction so that it protrudes in the transverse direction from the vertically extending section of the holding element. Particularly preferably, both the retaining lug and the retaining projection each extend outwardly in the transverse direction, i. H. starting from the section of the holding element which extends in the vertical direction and connects the holding lug and the holding projection, in the transverse direction away from the opposite holding section to the outside. The retaining spring according to the invention can generally have at least some of the features explained above in connection with retaining springs of the generic type.

According to the invention, the spring device is at least partially formed by a spring section which is formed by the holding element and / or the base element. According to the invention, such a spring section is integrated into the holding element and / or base element by appropriate shaping, this shaping preferably having a course extending with one component in the vertical direction and with one component in the transverse direction. Such a shape is implemented in a particularly simple manner in that the holding element and / or the base element are made from sheet metal and are reshaped to form the spring section. The spring section is particularly preferred by a section of the base element that extends vertically away from the base section and points vertically away from the base section and is bent over toward the holding element in the transverse direction formed, which in the starting position rests against the holding element along the transverse direction, in particular rests against the holding element in the vertical region of the holding projection. This bent section of the base element thus preferably rests against the holding element in a vertical area which has a vertical extension of less than a third of the total vertical extension of the holding spring and in the vertical center of which the holding projection lies. Particularly preferably, the above-mentioned bent-over section of the base element rests against the holding element above the holding projection. By integrating the spring section in the base element, the holding element can be designed to be particularly robust. In addition, a particularly simple construction of the retaining spring can thereby be made possible.

In one embodiment, a linear guide is provided between the holding element and the base element along the transverse direction, so that the holding element is guided so that it can be linearly displaced relative to the base element in the transverse direction. The linear displaceability along the transverse direction enables simple assembly and disassembly of the assembly body of a support rail with the aid of the retaining spring according to the invention. In addition, the linear guide defines a precise movement of the holding element relative to the base element, which further improves the stability of the holding spring. The linear guide is particularly preferably formed by a first guide section provided on the base element and a second guide section provided on the holding element. For example, one of the guide sections can be designed as a rail in which the other guide section is guided.

In one embodiment, an actuating section is provided on the holding element which extends in the transverse direction is arranged on the side of the holding element facing away from the opposite holding section and protrudes in the transverse direction by at least 5 mm over the holding projection. The fact that the actuating section protrudes beyond the holding projection enables simple actuation of the holding spring to detach the assembly body from the support rail. When the assembly body, support rail and retaining spring are arranged in relation to one another, the actuation section can extend in the transverse direction beyond the assembly body and the support rail, so that a technician for dismantling the assembly body on which the base element is fixed can move the actuation section inwards in the transverse direction, that is, can operate towards the holding section opposite the holding section of the holding element, whereby it can cancel the transverse overlap between the fastening projection and the holding projection of the holding element, so that the assembly body can be removed from the support rail. For this purpose, the mounting body and / or the mounting rail particularly preferably has a lateral recess through which the actuating section extends. The actuating section can for example be integrated in the holding element. The actuating section is particularly preferably designed as a further separate element of the retaining spring, which is held clamped and / or latched on the retaining element. The formation of the actuating section as a separate element is particularly advantageous, since this allows the holding element to be designed as robustly and appropriately as possible regardless of an intended actuation function, since the actuating section is only attached to the holding element when the holding spring is manufactured and is itself designed specifically for the best possible manageability can be. In one embodiment, the actuation section is provided by an actuation element that is separate from the holding element provided, which is preferably also a separate element from the base element. The actuating element can be releasably latched to the holding element. Particularly preferably, the actuating element can be latched to the holding element by being inserted along the transverse direction into a receptacle provided on the holding element, the receptacle having a stop for the actuating element that limits insertion in the transverse direction. Particularly preferably, the receptacle and the actuating element are designed to correspond to one another in such a way that the actuating element can be locked in the receptacle with the holding element. The actuating element is particularly preferably made of plastic. By producing the actuating element from plastic, on the one hand, the actuating element can be given a shape in a particularly simple manner in which it is suitable for locking with the holding element. On the other hand, this allows the actuating element to be designed in a particularly simple manner so that it can be comfortably actuated with one hand. Particularly preferably, the actuating section has an extension length perpendicular to the transverse direction, which increases in steps away from the holding projection along the transverse direction. In this embodiment, the step-like enlargement enables a stop of the actuating section on the mounting body and / or mounting rail so that actuation of the holding element, ie displacement of the holding element relative to the base element along the transverse direction, can be limited, thereby preventing overloading of the spring device can. For example, in one embodiment, the actuating section can extend with a section forming a first part of the step shape through a recess provided in the support rail and / or mounting body, with a second, larger section forming the step shape in the transverse direction outside the support rail and / or Extend mounting body, wherein the second section has a greater extent perpendicular to the transverse direction than the recess, whereby a stop can be effectively provided. In general, the base element and the holding element are held relative to one another in the holding spring in such a way that a vertical movement of the holding element away from the base section in a direction along the vertical direction is limited. When the bottom section is mounted on the mounting body in such a way that the bottom section is arranged vertically below the holding projection, the upward movement of the holding element relative to the base element is limited. This is of course necessary so that the retaining spring ensures a reliable fixation between the mounting body and the mounting rail that can withstand a force in the vertical direction. This holder, which limits the relative movement of the holding element relative to the base element, is particularly preferably provided by the same guide between the base element and the holding element that also ensures that the holding element is guided relative to the base element, which is movable in the transverse direction. In one embodiment, both the base element and the holding element each have a plate-shaped section for mounting, which runs perpendicular to the vertical direction, the plate-shaped sections in the holding spring being arranged so as to overlap each other perpendicular to the vertical direction, the plate-shaped section of the holding element preferably being vertically below the Plate-shaped portion of the base element is arranged and the holding projection and in particular the holding lug of the holding element are arranged vertically above the plate-shaped portion of the holding element and in particular vertically above the plate-shaped portion of the base element.

The retaining spring particularly preferably has a further, namely a second, element as a further separate element Holding element which is displaceable relative to the base element and relative to the first holding element in the transverse direction. The second holding element can be designed analogously to the first holding element, as explained in the above explanations. Particularly preferably, the first and second holding element each have a holding lug and a holding projection, which are each connected to one another by a section of the respective holding element running along the vertical direction, the holding projection and holding section of each holding element in the transverse direction from the holding element opposite in the transverse direction starting from the the vertical direction extending portion of the respective holding element extend away. Particularly preferably, the base element has a first guide section in that both the guide section provided on the first holding element and the guide section provided on the second holding element are guided, in particular are guided so as to be linearly displaceable in the transverse direction. The above explanations in relation to the first holding element and the base element are all applicable in preferred embodiments to the configuration of the base element relative to the second holding element. For example, the base element can have a first and a second spring section, the first spring section bearing against the first holding element along the transverse direction in the starting position, as explained above with reference to the first holding element, and the second spring section bearing against the second in the starting position along the transverse direction Holding element rests, wherein the two spring sections can be designed as explained above with reference to the first holding element. Particularly preferably, a further, ie second, actuating section is provided on the further, ie second holding element, which in the transverse direction is on the side of the further holding element facing away from the opposite holding element is arranged and protrudes in the transverse direction by at least 5 mm over the holding projection of the second holding element. The holding element of the further or second holding element lying opposite in the transverse direction is of course the first holding element. By providing an actuating section on each of the two holding elements, even release of the holding spring from the support rail for dismantling a mounting body from the support rail, to which the base element of the holding spring is attached, can be particularly advantageously made possible.

In one embodiment, the base element has fixing lugs on the transversal ends of its bottom section for fixing the base element to the assembly body. The fixing lugs can, for example, starting from the bottom section, be clamping lugs which run away in the vertical direction and which can clamp under a corresponding fixing projection of the assembly body.

The invention also relates to an arrangement comprising a retaining spring according to the invention, a support rail and a mounting body. In an operating position, the mounting body is held vertically at the bottom of the mounting rail by means of the retaining spring, wherein in the operating position the retaining element is pressed in the transverse direction against the mounting rail or the mounting body by the spring device. In the operating position, the holding projection is arranged vertically above the fastening projection and rests on it. The retaining lug is particularly preferably arranged vertically below the fastening projection and overlaps perpendicular to the vertical direction with a counter-section formed by the mounting rail or the mounting body, the retaining projection preferably resting on the fastening projection in the operating position and the retaining lug in The vertical direction is spaced apart from the mating section by less than 3 mm, in particular by less than 2 mm. The mating section is particularly preferably formed by a fixing projection of the assembly body. The fastening projection is particularly preferably formed by deforming a side wall of the support rail and the fixing projection is formed by deforming a side wall of the mounting body. The retaining spring particularly preferably has two retaining elements and the mounting rail has two fastening projections and, in particular, the mounting body has two fixing projections, the fastening projections and fixing projections each being formed by deforming side walls of the mounting rail or mounting body, and each of the retaining elements having a fastening projection and in particular is assigned to a fixing projection and, as explained above, each of the retaining projection and retaining lug of which are arranged relative to the assigned fastening projection and in particular to the assigned fixing projection. Particularly preferably, an actuating section as explained above is arranged on the holding element, which, starting from an interior space formed in the operating position of the mounting rail and mounting body, extends outward in the transverse direction beyond the mounting rail and / or mounting body. Of course, a corresponding actuating section can be provided on each holding element.

In Figure 1 comprehensive the Figures 1a, 1b , 1c, 1d , 1e and 1f an embodiment of a retaining spring 100 according to the invention and of separate elements of this retaining spring 100 are shown in various schematic schematic representations. Below are all of the Figures 1a to 1f explained together. The retaining spring 100 according to the invention has a base element 1 and two retaining elements 2, 3. The holding elements 2, 3 are designed identically. Base element 1, and the holding elements 2, 3 are each as formed separate elements, so that the retaining spring 100 is only realized by joining the separate elements. The retaining spring 100 also has an actuating element 4, which is a further separate element of the retaining spring 100.

The base element 1 has a bottom section 10 from which a spring section 12 extends vertically. Each of the spring sections 12 has a section which is bent over in the transverse direction Y in relation to the holding element 2, 3 assigned to the respective spring section 12 and which, in the starting position, rests against the assigned holding element 2, 3 along the transverse direction. In Figure 1a a passage of the respective spring section 12 through the respectively assigned holding element 2, 3 is shown in the schematic representation. In reality, of course, this is not the case and is only used for illustrative purposes in order to make it clear that the spring sections 12 are each already in the Figure 1a position shown exert a resilient bias in the transverse direction on the holding elements 2, 3. The spring sections 12 thus at least partially form a spring device which exerts a restoring force acting in the transverse direction Y on the holding elements 2, 3 when the holding elements 2, 3 are moved towards one another in the transverse direction Y. The spring device is also formed by the design of the holding elements 2, 3 themselves, since the holding elements 2, 3, as in FIGS Figures 1c and 1d can be seen, are L-shaped and thus provide a certain spring effect themselves. Out Figure 1a in sync with Figure 1b it can also be seen that the base element 1 has fixing lugs 11 with which the base element 1 is positioned under a fixing projection of a mounting body 200, such as in FIG Figures 2 and 3 to recognize can be jammed. From the synopsis the Figures 1a, 1b , 1c and 1d it can also be seen that the base element 1 forms a first guide section 13 and that the holding elements 2, 3 each form a second guide section 23, 33. The in Figure 1a The interaction of the guide sections 13, 23 or 13, 33 to be recognized is, on the one hand, a linear guidance of the holding elements 2, 3 relative to the base element 1 in the transverse direction Y. On the other hand, this also ensures a limitation of the movement of the holding elements 2, 3 vertically upwards relative to the base element 1, since the first guide section 13, which is designed in the manner of a guide rail, is applied from above onto the second guide sections 23, 33 of the Holding elements 2, 3 rests.

The embodiment according to Figure 1 furthermore has a separate actuating element 4, which is held on the first holding element 2 via a fixing device 24 provided on the first holding element 2. This fixing device 24 is designed as a clamping fixing device, so that the actuating element 4 can be pushed under this clamping device 24 and can be clamped sufficiently firmly with the first holding element 2. The first holding element 2 has stops 240 which, when the actuating element 4 is fixed on the first holding element 2, limit the movement of the actuating element 4 relative to the first holding element 2 along the transverse direction Y.

Out Figure 1 it can also be seen that the holding elements 2, 3 each have a holding projection 20, 30 and a holding lug 21, 31 arranged vertically offset from the respective holding projection 20, 30. Thus, between the retaining projection 20, 30 and the retaining lug 21, 31 of each retaining element 2, 3, a receptacle is formed in which a fastening projection arranged on a support rail, as in FIG Figure 3 to recognize, can be arranged. The retaining lug 21, 31 and the retaining projection 20, 30 are connected to one another by a flat sheet metal section running parallel to the vertical direction and overlap along the transverse direction Y. This ensures a particularly robust design of the retaining spring 100. A particular factor here is that the retaining lug 21, 31 is formed by sheet metal sections which are arranged laterally in the longitudinal direction on the vertically extending connecting section and which extend transversely outward from this connecting section.

How the in Figure 1 illustrated retaining spring 100 according to the invention is in particular from the synopsis of Figures 2 and 3 evident. In Figure 2 the retaining spring 100 is shown with its base element 1 fastened to a mounting body 200. In Figure 3a a plan view of a cross section of an arrangement comprising support rail 300, mounting body 200 and retaining spring 100 is shown. In Figure 3b is a section of the arrangement according to illustration Figure 3a shown, in which a section of the support rail 300, the mounting body 200 and the first holding element 2 are shown. It can be seen from the figures mentioned that each of the retaining elements 2 is arranged with its retaining lug 21 vertically under a fixing projection formed by the mounting body 200, but with its retaining projection 20 is arranged vertically above the fastening projection 301 of the support rail 300 and rests against it. The fastening projection 301 of the support rail 300 is formed by deforming the side wall 302 of the support rail 300, the fixing projection 201 of the mounting body 200 is formed by deforming one of the side walls 202 of the mounting body 200. From the synopsis of the Figures 2, 3a and 3b it can be seen that, based on the in Figure 3a shown operating position of the arrangement according to the invention taking place Force load on the mounting body 200 relative to the mounting rail 300 in the vertical direction downwards when the retaining element 2 is bent up in a manner that reduces the overlap of its retaining projection 20 with the fastening projection 301, the retaining lug 21 comes to rest on the fixing projection 201 of the mounting body 200, whereby a reduction in the above-mentioned overlap existing in the transverse direction Y between holding projection 20 and fastening projection 301 can be effectively limited, which leads to a reliable fixation of the mounting body 200 on the support rail 300 by means of the retaining spring 100 according to the invention. Furthermore, it can be seen from the cited figures that, with the aid of the actuating element 4, the mounting body 200 can be easily moved from the mounting rail 300 starting from the position shown in FIG Figure 3a The operating position shown can be released, since by actuating the actuating element 4 along the transverse direction Y, the transverse overlap between the fastening projection 301 and the retaining projection 20 can be eliminated, so that the assembly body 200 with the retaining spring 100 attached to it can then be released from the support rail 300 .

In Figure 4 comprehensive the Figures 4a and 4b a further embodiment of a retaining spring 100 according to the invention and an arrangement according to the invention with this embodiment of a retaining spring 100 according to the invention is shown. The embodiment according to Figure 4 differs from the previously described embodiments essentially in that the retaining spring 100 according to the invention has two separate actuating elements 4, each of which, as explained above, is fixed to a respectively assigned retaining element 2, 3. Correspondingly, the retaining spring can be released evenly in the transverse direction Y on both sides from the respective fastening projection 301 of the support rail 300 provided on the respective side wall, by moving the two actuating elements 4 towards one another in the transverse direction Y. At this point it should be noted that, as in Figure 2 To see, the mounting body 200 has a recess in each side wall 202, 203 through which the actuating element 4 extends. How out Figure 1e The actuating element 4 can be seen to have an extension length along the longitudinal direction that changes stepwise along the transverse direction Y, this extension length increasing in steps away from the associated holding projection 20, 30 of the associated holding element 2, 3 along the transverse direction Y. Correspondingly, the actuating element 4 extends with a section 41 that is narrower in the longitudinal direction through the recess provided in the mounting body 200, whereas the movement of the actuating element 4 in the transverse direction Y relative to the mounting body 200 is limited by the step formed. The delimitation is provided by the fact that the section 42 of the actuating element 4, which is wider in the longitudinal direction, rests on the outside of the mounting body 200 when the actuating element 4 is moved accordingly along the transverse direction Y relative to the mounting body 200. The actuating element 4 has an operating section 43 which can be easily touched and actuated by a person in order to detach the retaining spring 100 from the fastening projections 301 of the mounting rail 300 and thus to detach the mounting body 200 from the mounting rail 300.

In the Figures 5 to 7 a further embodiment of a retaining spring according to the invention is shown in schematic representations. Figure 5 shows a perspective view of the retaining spring 100, Figure 6 shows the retaining spring 100 in a mounting position in which it is attached to the top of a mounting body 200, and Figure 7 FIG. 13 shows a cross-sectional view showing the function of the retaining spring 100 becomes apparent during its intended use, in which it is attached with its base element 10 to a mounting body 200, as in Figure 6 shown, and the mounting body 200 is held on a mounting rail 300. The ones in the Figures 5 to 7 The embodiment shown has the same as that in FIGS Figures 1 to 4 The embodiments shown have two separate elements, of which a first element is designed as a base element 1 and a second element is designed as a holding element 2. As in the embodiments according to Figures 1 to 4 the retaining spring 100 also has a second retaining element 3, which is embodied identically to the first retaining element 2. The retaining spring 100 is as in the embodiments according to Figures 1 to 4 explained only realized by joining their separate elements. The retaining spring 100 according to FIGS Figures 5 to 7 the two holding elements 2, 3, the base element 1 and the two separate actuating elements 4, which are latched to the holding elements 2, 3 in receptacles provided on the holding elements 2, 3. While in Figure 5 for explanatory purposes, the embodiment described is shown without the actuating elements 4, so that the receptacles of the holding elements 2, 3 can be seen, are shown in FIGS Figures 6 and 7th the actuators 4 shown. The holding elements 2, 3 are each guided displaceably relative to the base element 1 by means of a guide along the transverse direction Y. On the one hand, a lateral guide is formed between the base element 1 and the holding elements 2, 3, in that the base element 1 encompasses the holding elements 2, 3 at their longitudinal ends in each case. In addition, the in Figure 5 A height guide is provided in that the holding elements 2, 3 each have a rear grip section 25, 35 which, in the starting position of the holding spring 100, vertically engages behind an assigned section 15 of the base element 1 and, in doing so, with this via a perpendicular to the vertical direction Z running surface overlaps. In the embodiment described, the rear grip sections 25, 35 of the holding elements 2, 3 and the sections 15 of the base element 1 assigned to the two rear grip sections 25, 35 are each designed in the manner of a U-hook, the open end of which is a transverse end, the closed ends of the both U-hooks are opposite each other in the transverse direction. On the one hand, this provides a height guide which limits a rotation of the holding elements 2, 3 relative to the base element 1 about the longitudinal direction X, which is perpendicular to the transverse direction Y and vertical direction Z, at least to an angle of less than 10 °; the associated sections 15 of the base element 1 have mutually corresponding stops of the base element 1 and holding elements 2, 3, so that the guide has a transverse path limitation and thus the holding elements 2, 3 are prevented from moving further towards one another in the transverse direction Y, starting from the starting position remove when the spring device exerts a corresponding spring force in the starting position, as is the case here. As already to Figure 1 explained at this point it should be noted that in the Figures 5 to 7 the spring sections 12, which are formed by the base element 1, are shown in such a way that they pass through the associated holding elements 2, 3. In reality, of course, this is not the case but is only intended to illustrate that in the starting position the spring device exerts a spring force on the holding elements 2, 3 in such a way that the holding elements 2, 3 are pressed apart along the transverse direction Y and thus their by the engagement sections 25 , 35 formed stops against the stops formed by the associated sections 15 of the base element 1.

From the Figures 5 to 7 it can also be seen that the Holding projection 20 of the holding element 2 has a contact surface 22 with which it rests in the assembly position on the fastening projection 301 of the support rail 300, the contact surface 22 extending obliquely vertically upwards towards the transverse end of the holding projection 20, whereby the in Figure 7 illustrated situation of the assembly body 200 is pressed along the vertical direction Z against the mounting rail 300. From the Figures 5 to 7 it can also be seen that the embodiment of a retaining spring 100 according to the invention shown therein has two catch hooks 5. Each of the catch hooks 5 is arranged in each case on one of two transversely opposite end regions of the holding spring 100 and projects vertically over the holding section assigned to it in the sense that it is arranged vertically above the holding section. In the embodiment described, and generally advantageously, each of the catch hooks 5 is arranged vertically above the holding projection 20, 30 assigned to it and thus projects vertically in front of this holding projection 20, 30. In the embodiment described, each of the catch hooks 5 is formed by one of the holding elements 2, 3 and, with reference to the transverse direction Y, has the same relative position relative to the holding projection 20, 30 assigned to it with each deflection of the holding elements 2, 3 along the transverse direction Y to one another Each of the catch hooks 5 protrudes along the transverse direction Y over the retaining projection 20, 30 assigned to it along the transverse direction Y in the sense that it extends further away from the transverse center of the retaining spring 100 along the transverse direction Y than the retaining projection assigned to it 20, 30. As already explained for the spring sections 12, the catch hooks 5 in FIG Figure 7 shown so that they penetrate the side walls of the support rail 300. This is only due to the illustration and is intended to illustrate that the catch hook 5 of the retaining spring 100 as such protrude transversely. In fact, with the cross-section as shown in Figure 7 is shown in a schematic diagram, the catch hook 5 of course on the inside of the side walls of the support rail 300 and press from the inside against the side walls. In the event that a particularly high vertical relative force acts between the mounting rail 300 and the mounting body 200, the configuration according to FIG Figure 7 It must be ensured that even if the retaining projections 20, 30 slide from the associated fastening projections 301 due to a jerky load, the catch hooks 5 can grip behind the fastening projections 301 and thus prevent the assembly body 200 from being completely detached from the support rail 300. The catch hook 5 thus provide a safeguard that serves to prevent damage to a lamp that is used as the basic structure in Figure 7 having illustrated elements to avoid. In the illustrated embodiment, for example, the catch hooks 5 can grip behind the fastening projections 301 when the holding projections 20, 30 have slipped from the fastening projections 301, so that the in Figure 7 The connection shown can be achieved again by moving the mounting body 200 again along the vertical direction Z towards the mounting rail 300 until the holding projections 20, 30 with their contact surfaces 22, 32 rest on the upper side of the fastening projections 301.

That in the Figures 5 to 7 The illustrated embodiment of a retaining spring 100 according to the invention furthermore has a holder for retaining cables in a transverse region around its transverse center. The holder comprises two holding legs 61, 62, which each run transversely from the outside to the transversal center. The holding legs 61, 62 lie opposite one another in the transverse direction Y and are like this in the exemplary embodiment described designed that their ends facing one another in the transverse direction Y are spaced apart from one another. In addition, the transversal ends of the holding legs 61, 62 have run-up bevels 611, 621, so that cables can be brought between the base section 10 and the holding legs 61, 62 in a particularly simple manner, for example by a robot. In the exemplary embodiment described, the bottom section 10 of the base element 1 and the holding legs 61, 62 thus form a receiving space for cables. In other advantageous embodiments, the holding legs 61, 62 can also be arranged in such a way that they overlap in sections along the transverse direction Y with their transversal ends lying opposite one another in the transverse direction Y. As a result, an even better securing of cables can be guaranteed by the retaining legs. In the embodiment described, and particularly advantageously in general, the retaining legs 61, 62 are designed so that, starting from the starting position in which their transverse ends abut one another or are spaced apart, they can be elastically deflected while increasing the distance between their transverse ends, so that the elastic deflection of the retaining legs 61, 62 to one another, starting from the starting position, a gap can be created between the retaining legs 61, 62 through which operating elements, such as cables, can be passed.
