Fixture for attaching a profile rail to another component

A fixture for attaching a profile rail comprising an undercut longitudinal groove to a component disposed to support the profile rail, the fixture comprising:

• a main body comprising:
• a flat planar bearing surface for the profile rail,
• a rear surface disposed opposite to the flat planar bearing surface,
• a hook segment projecting from the flat planar bearing surface so as to divide the flat planar bearing surface into two coplanar partial surfaces so that the profile rail can rest on each of the two coplanar partial surfaces, the hook segment being configured to engage the undercut longitudinal groove, and
• a slide ramp comprising a second opening, the slide ramp protruding outwardly away from and rising relative to the flat planar bearing surface and being parallel to the hook segment;
• a clamping screw means configured to clamp the profile rail to the fixture and to tighten the fixture to the component at the rear surface;
• and
• a gripping wedge of essentially triangular cross section comprising a top side parallel to the flat planar bearing surface, a gripping side vertical to the flat planar bearing surface, and a first opening, the gripping wedge being disposed on the slide ramp and being configured so as to be slidable via the clamping screw means such that the gripping side contacts the profile rail so as to slide the profile rail along the two coplanar partial surfaces of the flat planar bearing surface and clamp the profile rail against the hook segment;
• wherein,
• the clamping screw means is configured to penetrate the first opening of the gripping wedge and the second opening of slide ramp,
• at least one of the first opening and the second opening is a longitudinal opening oriented perpendicular to the hook segment, and
• the main body is arranged to be between the profile rail and the component.

A fixture for attaching a profile rail (20) having an undercut longitudinal groove (21) to another component (30, 31, 40) disposed to support the profile rail (20), the fixture comprising a main body (1), a gripping wedge (2), and a clamping screw (3, 3′), wherein:

• the main body (1) has a flat planar bearing surface (6) for the profile rail (20) and a linear hook segment (7) projecting from the flat planar bearing surface (6), the linear hook segment being designed to engage the undercut (21) of the longitudinal groove (20);
• the main body (1) has a slide ramp (10) that protrudes outwardly away from and rises relative to the flat planar bearing surface (6) and parallel to the linear hook segment (7);
• the gripping wedge (2) has an essentially triangular cross section comprising a top side parallel to the flat planar bearing surface (6), a gripping side vertical to the flat planar bearing surface (6), and a first opening, the gripping wedge (2) being disposed on the slide ramp (10) and being configured so as to be slidable via the clamping screw (3, 3′) such that the gripping side contacts the profile rail (20) so as to slide the rail along the flat planar bearing surface (6) and clamp the profile rail (20) against the linear hook segment;
• the clamping screw (3, 3′) penetrates the gripping wedge (2) in the first opening (11) and the slide ramp (10) in a second opening (12), wherein the first and/or second opening (11, 12) is a longitudinal opening (12) oriented perpendicular to the linear hook segment (7);
• the main body (1) has a rear surface (9) opposite the flat planar bearing surface (6), to which rear surface the fixture can be tightened by one and the same clamping screw (3, 3′) against the another component (30, 31, 40);
• wherein the main body (1) is disposed to be arranged between the profile rail (20) and the another component (30, 31, 40);
• and
• an elastically-functioning loss-prevention means (5) is provided in a top section of the slide ramp (10), the elastically-functioning loss-prevention means (5) being configured to retain the gripping wedge (2) on the slide ramp (10), the elastically-functioning loss-prevention means (5) being a rubber ring (5) inserted both in a groove on a rear-side area of the slide ramp (10) and in a groove on the gripping side of the gripping wedge (2) facing the profile rail (20).
