Abstract

A clamping device for clamping a conduit to a channel rail, comprising a main unit with a retainer section of which the shape fits the sectional form of the conduit, a screw member and a buckle. Just pushing the screw member axially causes abutments of the buckle to be engaged on the channel rail and thus the conduit is fixed to the channel rail at least provisionally. The abutments of the buckle are made to engage the channel rail just when the screw member is pushed axially by holding the buckle in a predetermined direction in the main body until the screw member is pushed axially, rotating the buckle when the buckle is released from the held state so that the abutments are positioned under the lower ends of a pair of inlet-opening walls defining together an inlet opening of the channel rail, and drawing the buckle in the direction of the head of the screw member while the abutments are kept positioned under the lower ends of the pair of walls.

Dependent claims

A device for clamping a conduit having a curvature to a channel rail, said channel rail comprising a web having respective sides, a pair of flanges, each flange extending from a respective side of said web and having an upper end, a pair of top walls extending inwardly from said respective upper ends of said flanges, said pair of top walls having respective bottom faces and terminating so as to form an inlet opening therebetween having a first width (W.sub.1), said device comprising a main body having a retainer section and a seat section, said seat section having an aperture;

a screw member positioned in said aperture and having a head and a threaded body;
a buckle mounted on said screw member, said main body comprising holding means for releasably holding the buckle in a predetermined direction and below said seat section, and said buckle comprising, said longitudinal end parts forming base and longitudinal end parts as channel rail engaging means for engaging said pair of top walls of said channel rail and at least provisionally fixing said conduit to said channel rail, said engaging means comprising a pair of abutments extending upwardly from said base;
and rotating means for rotating said buckle when said buckle is released from said holding means so that said abutments are positioned under a respective bottom face of said pair of top walls of the channel rail, said rotating means further for drawing said buckle in the direction of said seat section so that said abutments are kept positioned under the respective bottom face of said pair of top walls.

A device for clamping a conduit to a channel rail, comprising in combination, said device and wherein said conduit is positioned substantially perpendicularly to said channel rail, said channel rail comprising a web having respective sides, a pair of flanges, each flange extending from a respective one of said sides of said web, said flanges being separated from one another by a first distance (W.sub.2) and having respective upper ends, and top walls extending inwardly from said respective upper ends, said top walls terminating so as to form an inlet opening therebetween having a second distance (W.sub.1);

said device comprising:
a main body and a buckle attached to said main body by a screw member and a spring disposed about said screw member, said buckle being rotatable with respect to said main body;
said buckle having a width (W) smaller than said second distance (W.sub.1) and a length (L) larger than said second distance (W.sub.1) but smaller than said first distance (W.sub.2);
said buckle having a middle and a screw hole in said middle thereof, said buckle comprising a base having lateral sides extending from said lateral sides and forming longitudinal end portions;
a pair of abutments at each end of said base;
and a pair of projections extending from said lateral sides of said base, said pair of projections being higher than said abutments so as to form symmetrical stop faces therebetween;
said main body comprising a foot section having a portion engaging said walls of said channel rail, a retainer section contiguous from said foot section for holding said conduit, and a seat section extending from said retainer section, said seat section having lateral bent walls which cooperate with said pair of projections for releasably holding said buckle so as to be longitudinally parallel to the inlet opening of the channel rail, said seat section having a through-hole through which said screw member extends and is screwed into said screw hole in said buckle;
and
said spring having a first end and a second end and being disposed between said seat section and said buckle, said spring member being coupled at said first end thereof to said seat section and at said second end thereof to said buckle, whereupon said spring, when being twisted, lifts said buckle and provides rotation to said buckle.
