Clamp assembly for a standing seam
First Claim
1. A clamp assembly for securing an ancillary device (16) to a standing seam (8) interconnecting metal panels (4, 6), the standing seam comprising a protruding web portion (10) with a head portion (12) at an outer extremity thereof, the clamp assembly comprising:
- a substantially rigid member (18);
first and second substantially rigid arms (22, 24) extending from the member, at least one of the arms (24) being pivotally interconnected with the member at at least one hinge means (28), the first and second arms having first and second free extremities (36, 38), the first arm (22) forming an integral part of the member (18), without pivotal interconnection thereto, and the second arm (24) having a portion (26) which extends to overlie the member and is pivotally interconnected therewith at the hinge means (28), and adapted to receive the ancillary device (16);
threaded fastener means (40, 41) engaging in a complementary threaded aperture (46) in the member, the threaded fastener means (40, 41) being adapted to pass through the ancillary device, through an aperture (44) in the extending portion of the second arm, and into the complementary threaded aperture (46) in the underlying member, wherein the or each hinge means (28) pivotally interconnecting the at least one of the first and second arms (22, 24) to the member (18) comprises a groove (32) provided in one of the or each arm and the member into which is axially slid a complementary protrusion (34) extending correspondingly from the other of the member and the or each arm, the groove having a wall thereof subtending an angle of more than 180 degrees, whereby retention of the protrusion in the groove is obtained, the hinge means being adapted and arranged to permit pivoting between the second arm, on its extending portion, and the first arm fixed to the member, for locating the clamp assembly on the standing seam, the threaded fastener means being adapted to be subsequently tightened to pivot the extending portion of the second arm towards the underlying member, whereby the first and second free extremities (36, 38) of the first and second arms are caused to converge to grip the web portion (10) of the standing seam (8).

Abstract
A clamp assembly is provided for securing an ancillary device (16) to a standing seam (8), the standing seam comprising a protruding web portion (10) with a head portion (12) at an outer extremity. The clamp assembly includes a substantially rigid member (18; 54) adapted to overlie and contact the head portion of the standing seam. First and second substantially rigid arms (22, 24; 58, 60) extend from the member and are adapted to embrace the head portion in co-operation with the member, at least one of the arms (24; 58, 60) being pivotally interconnected with the member at hinge means (28; 62, 64). The first and second arms have first and second free extremities (36, 38; 70, 72) adapted to face one another and to contact opposite sides of the web portion. Threaded fastener means (40, 41; 86) passes through the ancillary device and into a threaded aperture (46; 88) in the member, from an outer surface of the member. The hinge means permits pivoting of at least one of the first and second arms and separation of the first and second free extremities of the first and second arms, for locating the clamp assembly on the standing seam. The threaded fastener means is subsequently tightened to clamp the ancillary device and grip the web portion of the standing seam in jaw-like manner by the first and second free extremities of the first and second arms.

11. A clamp assembly for securing an ancillary device (16) to a standing seam (8) interconnecting metal panels (4, 6), the standing seam comprising a protruding web portion (10) with a head portion (12) at an outer extremity thereof, the clamp assembly comprising:
- a substantially rigid member (54);
first and second substantially rigid arms (58, 60) extending from the member, at least one of the arms (58, 60) being pivotally interconnected with the member at at least one hinge means (62, 64), the first and second arms having first and second free extremities (70, 72);
threaded fastener means (86) engaging in a complementary threaded aperture (88) in the member, wherein the or each hinge means (62, 64) pivotally interconnecting the at least one of the first and second arms (58, 60) to the member (54) comprises a groove (82) provided in one of the or each arm and the member into which is axially slid a complementary protrusion (84) extending correspondingly from the other of the member and the or each arm, the groove having a wall thereof subtending an angle of more than 180 degrees, whereby retention of the protrusion in the groove is obtained, and wherein the first and second substantially rigid arms (58, 60) are both pivotally interconnected, by respective hinge means (62, 64), with opposite sides of the substantially rigid member (54) at an intermediate location (66, 68) on the arms, the first and second arms having third and fourth free extremities (74, 76) respectively at opposite ends thereof to the first and second free extremities (70, 72) respectively, the third and fourth free extremities of the arms and an outer surface of the member being adapted to receive the ancillary device (16) and the outer surface of the member being provided with the threaded aperture (88), the first and second arms being adapted and arranged such that when the ancillary device is not secured in contact therewith, the first and second arms are pivotable into a position whereby the first and second free extremities are separated to permit the clamp assembly to be located on the standing seam and the third and fourth free extremities extend angularly beyond a plane of the outer surface of the member, and such that when the ancillary device is subsequently secured by tightening the threaded fastener means (86), the first and second arms are pivoted by contact of the third and fourth free extremities thereof with the ancillary device, whereby the ancillary device is secured to the member, the third and fourth free extremities of the first and second arms being urged outwardly into coplanar relationship with the outer surface of the member, and the first and second free extremities of the first and second arms are urged towards each other and into secure gripping engagement with the web portion (10) of the standing seam (8). - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
