Abstract: A slider system for a profiled bar (10.1), especially a bar of extruded light metal, which, is provided in predefined cross-sectional system axes (A, B) with an undercut longitudinal groove (12) on a respective side or at least one outer side having a predefined width (B1). At least one slider profile section (20.1) is connected to the profiled bar and is able to be displaced in direction of said profiled bar. The invention is characterized in that at least one slider profile (20.1) having at least one undercut inner longitudinal groove (22) which is arranged on one of the cross-sectional system axes (A, B) when the slider profile (20.1) is connected to the profiled bar, and by at least one sliding guide profile (14) which engages with the longitudinal groove (12) of the profiled bar (10.1) and the corresponding opposite inner longitudinal groove (12) of the slider profile (20.1) from the rear.

Abstract: A connector device for connecting a first profile to the end side of a second profile with a central recess having a connector bolt with a shank and an end contour. When the connector is installed, the end contour engages with a clamping action behind a recess, in particular a groove, in the first profile. Here, the connector bolt is adjoined, on the end side which is located opposite the end contour, by an extension element with an end stop, and the extension element is slidingly mounted in a bushing. In addition, an elastic element is provided between the bushing and the connector bolt. This elastic element acts directly or indirectly on the sliding bushing and the connector bolt.

Abstract: A connecting device for connecting at least two profiled bars that are essentially perpendicular to one another and have grooves, in conjunction with sliding blocks, one plate connector unit is fastened to the end of a first profiled bar and anchored in a groove in the second profiled bar by way of screw units they extend in recesses in the plate connector unit. The geometry of the screw head of the screw unit is configured such that it centers the screw unit within the groove in the first profiled bar and the engages with a centering effect in the groove in the second profiled bar.

Abstract: A profile-connecting device for connecting two profile bars. The first profile bar has an end side which abuts a longitudinal side of a second profile bar. At least the outer longitudinal side of the second profile bar which is directed toward the end side of the first profile bar and at least one outer longitudinal side of the first profile bar has an undercut groove.

Abstract: A connector device (10.1) for connecting a first profile (26) to the end side of a second profile (28) with a central recess (80), having a connector bolt (12.1) with a shank (40) and an end contour (14), it being possible for the shank (40) of the connector bolt (12.1) to be arranged and fixed in the central recess (80) of the second profile (28), and the end contour (14), in the installed state of the connector device, engaging with clamping action behind a recess, in particular a groove (42), in the first profile (26), is characterized in that the connector bolt (12.1) is adjoined, on the end side which is located opposite the end contour (14), by an extension element (30.1) with an end stop (32), the extension element (30.1) is mounted with sliding action in a bushing (34) which can be fixed with clamping action in the central recess (80) of the second profile (28), and provided between the bushing (34) and the connector bolt (12.

Abstract: A profile-connecting device (10) for connecting two profile bars (20; 30), in particular made of light metal, of which a first profile bar (20) has an end side butting against a longitudinal side of a second profile bar (30), at least that outer longitudinal side of the second profile bar (30) which is directed toward the end side of the first profile bar (20) and at least one outer longitudinal side, in particular two mutually opposite outer longitudinal sides, of the first profile bar (20) having an undercut groove (32; 22), is characterized by a clamping unit (13), which, at least in certain regions, has an outer contour which can be clamped in the groove (22) by virtue of being widened, a screw unit (14) which can be introduced into a continuous cutout (27) of the clamping unit (13), and a threaded unit (16) which can be introduced with rear-engagement action into the groove (32) of the second profile bar (30), the clamping unit (13) being spread apart, and thus clamped in the groove (22) of the first pro
