Patent number: 8650827Abstract: An assembly (14, 16) for securing two juxtaposed panels (64, 66) to a structure (74), each panel including a joining flange (68, 70) located at, or adjacent to, respective juxtaposed edges thereof. The assembly includes a retaining member (14) having a substantially planar surface (24) supporting at opposite edges thereof respective first flanges (26, 28) and a clamping member (16) having two spaced-apart legs (48, 40) depending from a web (36). Second flanges (46, 48) are each supported on a facing internal surface of a respective one of the legs so as to extend away from the web. Each leg engages a respective exposed surface of an adjacent joining flange, the first and second flanges being oriented in opposite directions so as to interlock when the clamping member is mounted on the retaining member and thereby limit lateral separation of the legs.Type: GrantFiled: June 3, 2008Date of Patent: February 18, 2014Assignee: Dan-PalInventors: Shaul Givoni, Nir Ben-Zvi
