Application Date: Dec. 15, 1954. No. 36346/54. Complete Specification Published: July 31, 1957. Index at acceptance: -Class 44, BE5A. International Classification:-F06b. jCOMPLET.E SFEOIFIOrCATION Improvements in Clamping Devices for Shelves, Panels or the like We, FREDERICK SAGE (DISPLAY FITTINGS) LIMITED, a Company organised under the laws of Great Britain, of Verulam Street, Gray's Inn Road, in the County of London, do hereby declare the invention, for which we pray that a patent may be granted to, us, and the method by which it is, to be performed, to b.e particularly described in and by the following statement:'The invention relates to clamping devices for securing glass or other shelves, panels or the like to supports or to, one another in a number of different relative positions for use as display stands. A clamping device for the above purpose has been suggested hiterto comprising two bifurcated members having clamping screws for clamping them to shelves or partitions, one bifurcated member having a socket and the other a cooperating spigot, so shaped, for instance, rectangular, that it can be securely held against rotation, in the socket in different relative positions in which, the two members may be united. A clamping device according to the invention comprises two bifurcated members provided with clamping means, one member having a strip or rail formed on it and extending beyond one face against which face either of two faces of the other member can be selectively abutted and the two members be secured together by a screw passing through the
- 2. abutting faces, the strip or rail then preventing any relative rotation. In the accompanying drawings: Figures 1 to 5, are, respectively, a front elevation, side elevation, rear elevation, plan and inverted plan of one bifurcated, member; Figures 6 to 10 being similar views of the other. Figures 111 to 14 are isometric drawings of pairs of members united in four different relative positions. In the example illustrated by these drawings, each of two similar bifurcated members 1, and 2 consist of two parallel rectangular parts 3, 4 spaced apart and, formed integrally with a square portion '5 at one end.. One rectangular part 3 of each member is drilled at 10 and screw threaded to, receive 50 a clamping screw 9 for clamping it to a support or to a shelf inserted between the two parts 3 and 4. The outer face 6 of the other rectangular part 4 and the outer face of the square end 55 portion 5 of each member are fat.. The rectangular part 4 and the square end portion '5 of the member 1,are drilled at 11 and 12 respectively and tapped for a connecting screw.7. (Figures. 11, 13 and '14). 60 TChe square end portion 5 of the other member 2 has a countersunk plain hole 13 for the connecting screw 7. The member 2 is also provided with a strip or rail 8 on one rectangular face which extends beyond the 65 square end porton 15. The arrangement is such that when the member 2 is applied to the member 1 with the faces of the end portions 5 abutting against one another in any of four positions, or is 70 applied to the flat rectangular face 6 'of the member 1 in' any of three different positions, the screw threaded hole 12 in the member 1 and the plain hole 113, in the other for the connecting screw.7 will always coindide to enable the screw to be inserted and tightened. Moreover the strip or rail 8 on the member Z engages over the adjacent surface of the other member,1 so that no relative movement between the members 1, and, 2 can occur. 80 The device thus forms a clamp permitting a shelf or other part to be removable but firmly supported in any of a number of selected positions relatively to a standard or other support. 85 Four different adjustments are shown in Figures 1,1---4. * Sitemap * Accessibility * Legal notice * Terms of use * Last updated: 08.04.2015 * Worldwide Database
