Description

The invention relates to a system for the realization of a longitudinally elongate lamp according to the preamble of claim 1. Furthermore, the invention relates to a method for producing such a system.

Generic systems are used for the realization of elongated luminaires, which are commonly referred to as strip lights. Such generic elongated lights or strip lights form a separate genus of lights that are used in a wide range of applications, for example in warehouses, production halls or supermarkets. To ensure that these luminaires can be used in a wide range of applications, these luminaires have a modular structure. In addition, the luminaires are designed so that they can be easily mounted on the site in any length. For this purpose, the basic structure of such luminaires is formed by support rails elongated in a longitudinal direction, each having a cross-section perpendicular to the longitudinal direction, which is open along one vertical direction at one end and at least partially closed at the opposite end, and along a transverse direction through two sidewalls is limited. Vertical direction and transverse direction are perpendicular to each other and each perpendicular to the longitudinal direction. The support rails are usually attached to a ceiling so that the open end of the cross section of the support rails facing away from the ceiling to the room, so that in the support rails bulbs can be provided, which emit light through the open end of the cross section of the support rails in the room , The support rails usually have a cross section in the manner of a U-shape with a U-bottom and U-side walls, wherein the bottom of the open end of the cross-section is opposite and the attachment of the support rails takes place on a ceiling or wall over the U-bottom. To realize the elongated lights or light bands, the mounting rails are arranged side by side in the longitudinal direction and connected to each other via a connector, so that the support rails are fixed by the connector in their relative position to each other. In most cases, the support rails are closed at the open end of its cross section by a cover in the lights.

To realize the described generic elongated lights, a generic system is used.

A generic system comprises at least two longitudinally elongated mounting rails for receiving bulbs and at least one longitudinally elongated connector for mechanically connecting two longitudinally juxtaposed mounting rails.

To realize an illustrated generic luminaire, the various elements of the system are arranged in an operating position to each other. The operating position thus describes the relative arrangement of the components of the system, which is required to realize a lamp. In the operating position, a first and a second mounting rail are arranged side by side in the longitudinal direction.

In addition, in the operating position, the connector is arranged on the two mounting rails, in particular arranged within the cross section of the two mounting rails, wherein the connector in the operating position connects the two mounting rails together.

To produce longer light bands, several mounting rails must be held together. This places particularly high demands on the stability of the system. Robust contact between the connector and the mounting rails is critical to the stability of the system.

The present invention has for its object to provide a system for realizing a longitudinally elongated lamp that is robust and easy to manufacture and improves the stability of the lamp.

As a solution to the problem underlying the present invention, the invention proposes a system having the features of claim 1 and a method having the features of claim 16. Preferred embodiments of the invention are subject matters of the subclaims.

The system comprises at least two longitudinally elongated support rails for receiving bulbs and at least one longitudinally elongate connector for mechanically connecting two longitudinally juxtaposed mounting rails. The support rails and the connector each have a cross section perpendicular to the longitudinal direction in the form of a kind of a U with a bottom and two side walls which extend from the ground along a vertical and which are connected along a transverse direction through the ground. Each of the support rails has on both side walls on a longitudinal guide, in which the connector from a longitudinal end of the respective support rail is inserted. The longitudinal guide is one of an embodiment within the respective support rail, ie formed within the U-shape of its cross section. In another embodiment, the longitudinal guide is formed on the outside of the side walls of the respective support rail. The longitudinal guide forms, based on the vertical, an upper and a lower leading end. The connector is inserted in an operating position in the longitudinal guide of the two support rails and connects the mounting rails together. The upper and lower leading ends of the longitudinal guide provide support surfaces for the connector in the operative position. The connector abuts in the operative position at the upper and lower leading ends of the longitudinal guide. Thanks to the longitudinal guide, the connector can be inserted along the longitudinal direction at least with a longitudinal portion of its extension length in the longitudinal guide of a mounting rail. In the retracted state, a positive connection, in particular a positive connection between the connector and the mounting rail, is preferably ensured. The longitudinal guide serves for optimal alignment of the inserted connector within the mounting rail and the fixing of the connector relative to the mounting rail. In the operating position, the connector connects two longitudinally adjacent support rails, which preferably abut each other in the operating position with their longitudinal ends facing each other or by less than 2 mm, in particular less than 1 mm with respect to the longitudinal direction spaced from each other, wherein in the operating position of the Connector is inserted into the longitudinal guide of each of these two adjacent support rails and as explained about the interaction with the longitudinal guide is fixed relative to the respective support rail, whereby the two adjacent support rails are fixed to each other. Particularly preferably, the support rails and the connector are each made of a metal sheet, which is first cut out, in particular punched, for the production of the respective support rail or the connector, and is then formed, whereby the support rail or the connector obtained their shape.

The longitudinal guide may be integrally formed with the side walls, in particular in the form of shoulders which extend from the side walls of the support rail in the transverse direction to the respective opposite side wall, in particular in the form of paragraphs produced by forming, in particular roll shapes. The longitudinal guide may be formed on both sides on the inner sides of the two side walls so that the lower and the upper guide end in each case by a shoulder of the vertically extending side wall which extends in the transverse direction, is formed. The upper leading end may be formed by the transversely extending bottom of the U-shaped support rail, which may accordingly form an illustrated paragraph extending away from both side walls in the transverse direction. In one embodiment, the longitudinal guide may be attached to the inside of the side walls in the form of guide rails.

According to the invention, the side walls of the connector each comprise a vertically extending along the vertical holding portion which is bounded by an upper and a lower end, wherein the upper and the lower end of the rectilinear holding portion abut the upper and lower guide end of the longitudinal guide. Preferably, the holding portions each form an absolute end of the connector with respect to the transverse direction.

The upper and the lower end of the holding portion of the connector abuts at least in sections on the upper and lower guide end of the longitudinal guide, so that a positive connection of the connector to the mounting rail can be ensured. This type of connection ensures a necessary rigidity of the lamp and is designed to counteract sagging of the lamp at the location where two of the mounting rails are connected. Particularly preferably, the holding section over at least 10%, in particular over at least 20% of its extension length at the upper leading end of the support rails and at least 10%, in particular over at least 20% of its extension length at the lower leading end of this support rail. The extension length in the longitudinal direction of the holding portion is defined over the length, within which the side wall having the holding portion has an identical extension in the vertical direction, is rectilinear and is arranged in the operating position in the longitudinal guide. In one embodiment, the holding portion is a longitudinally continuous longitudinal portion of one of the side walls, in one embodiment, the holding portion is formed over a plurality of part holding portions of one of the side walls which are longitudinally spaced from each other, but each having an identical extension in the vertical direction, straight and in the operating position are arranged in the longitudinal guide.

Surfaces of the rectilinear holding portion need not be smooth or straight, for example, the holding portion may have a varying thickness along the transverse direction. In any case, as the holding section is rectilinear, there is an imaginary straight line that extends over the entire vertical extension of the holding section in the transverse direction within the cross section of the side wall having the holding section, wherein the straight line preferably runs parallel to the vertical. Preferably, the holding portion has a length along the vertical direction, the at least 2 cm, in particular at least 3 cm, in particular at least 5 cm. The surfaces of the holding section which delimit the holding section with respect to the transverse direction preferably extend parallel to the straight line, in particular parallel to the vertical. The described rectilinear configuration of the holding portion between the upper and the lower end minimizes its spring property in the operating position, in which the upper and the lower end of the holding portion abut respectively at the upper and lower leading end of the longitudinal guide. Preferably, the rectilinear holding portion is perfectly straight.

The rectilinear holding portion extends at least over a part of the entire length with respect to the longitudinal direction of the connector. The extension length of the holding portion along the longitudinal direction is preferably between 5% and 30%, in particular between 10% and 20% of the total extension length of the connector. This can be particularly advantageous for a sufficient length of the holding portion, on the other hand, a sufficient stability of the connector can be ensured. The holding portion may include a plurality of spaced apart in the longitudinal direction of the connector part holding portions whose common length forms the extension length of the holding portion along the longitudinal direction.

The system according to the invention brings with it particular advantages compared to conventional systems. The vertically rectilinear holding portions, which abut respectively at the upper and lower guide end of one of the side walls of the support rails, allow an advantageous power transmission from the support rails to the connector with a particularly low spring action. The connector does not include spring loaded parts and no elastic parts. High strength of the connection between the mounting rails and the connector in the operating position leads to a high bending stiffness of the assembled luminaire or the light band in the region of the connector and allows the production of long light bands.

In one embodiment, the vertically rectilinear holding portions of the connector define the connector in the transverse direction. Preferably, the holding portions form the absolute outermost ends of the connector in the transverse direction.

Preferably, in the operating position, the rectilinear holding portions of the connector at the rectilinear wall portions of the support rails in the transverse direction or at least over its vertical extent continuously spaced by less than 2 mm, in particular at most 1 mm from them. Request means a contact over at least a partial area of the sections. Each of the rectilinear wall portions of the support rails extends between two immediately adjacent bending edges that form the leading ends. The fact that two immediately adjacent bending edges form the leading ends of the longitudinal guide, and thus no further bending edge but only the rectilinear wall portion is provided vertically between the two immediately adjacent bending edges, the longitudinal guide has a high rigidity, as a spring action between the leading ends of the longitudinal guide Possibility is avoided. Accordingly, the holding section between the leading ends is guided very stable.

In one embodiment, the side walls of the connector are each connected to the bottom of the connector via a longitudinal edge.
