Patent number: 7571898Abstract: A counter-balance weight for a modular safety rail includes a solid body of a compact shape which defines a substantially planar major surface which, in use, is intended to rest on a support surface The body defines a substantially linear through-bore for receiving an end of a spacer member. The through-bore extends continuously through the body in a direction substantially parallel with the substantially planar major surface of the body. The through-bore extends between a pair of end faces which, at least in part, are non-parallel end faces and the body further defines a screw-threaded aperture which extends through the body to intersect and communicate with the through-bore. The body may have a substantially triangular shape in transverse cross-section.Type: GrantFiled: April 5, 2005Date of Patent: August 11, 2009Assignee: Kee Klamp LimitedInventors: Philip Maurice Higgs, Charles William Stratford Presant, Francis Donald Tegg

Patent number: 6942199Abstract: A counter-balance weight for a modular safety rail comprises substantially only a solid body of a compact shape wherein the volume of the material of the body is at least 20% of the volume of the smallest cuboid which is able to contain the body, the body defining a through-bore for receiving an end of a spacer member and the body further defining a screw-threaded aperture which extends through the body to communicate with said through-bore. The body may have a substantially triangular shape in transverse cross-section.Type: GrantFiled: November 5, 2002Date of Patent: September 13, 2005Assignee: Kee Klamp LimitedInventors: Philip Maurice Higgs, Charles William Stratford Presant

Patent number: 6848679Abstract: A connector for a modular safety rail comprises a unitary combination of a body portion and two socket formations. The body portion comprises first and second flange formations which each define a substantially planar support surface, the support surfaces lying substantially perpendicular relative to one another in an āLā shape configuration as viewed along the line of intersection of the support surfaces. The support surfaces facing outwardly, and opposite inwardly facing surfaces of the flange formations each have integral therewith a respective one of the socket formations. Each socket formation has an outer end for receiving a tube or rod and an inner end region which is integral with the inner end region of the other socket formation of the pair, the longitudinal axis of each socket formation extending substantially perpendicular to the line of intersection of the support surfaces.Type: GrantFiled: September 13, 2002Date of Patent: February 1, 2005Assignee: Kee Klamp LimitedInventors: Philip Maurice Higgs, Charles William Stratford Presant

Publication number: 20040065794Abstract: A support foot for a modular safety rail system comprises a base plate having upper and lower surfaces and an outer periphery, a plurality of sockets positioned inwards of the periphery and extending from the upper surface for location of a vertical post, a plurality of webs provided at the upper surface and each extending from a socket towards the periphery, each web extending from the base plate to an upper edge surface of the web, the lower surface of the base plate having at least one recess whereby when one support foot is stacked on top of another at least one of a distal end of a socket and an upper edge of a web engages the recess to prevent lateral movement of the feet, and the upper edge surface of each web being able to support the lower surface of a superimposed support foot to resist toppling.Type: ApplicationFiled: July 3, 2003Publication date: April 8, 2004Inventors: Philip Maurice Higgs, Charles William Stratford Presant

Publication number: 20030094604Abstract: A connector for a modular safety rail comprises a unitary combination of a body portion and two socket formations. The body portion comprises first and second flange formations which each define a substantially planar support surface, the support surfaces lying substantially perpendicular relative to one another in an ‘L’ shape configuration as viewed along the line of intersection of the support surfaces. The support surfaces facing outwardly, and opposite inwardly facing surfaces of the flange formations each have integral therewith a respective one of the socket formations. Each socket formation has an outer end for receiving a tube or rod and an inner end region which is integral with the inner end region of the other socket formation of the pair, the longitudinal axis of each socket formation extending substantially perpendicular to the line of intersection of the support surfaces.Type: ApplicationFiled: September 13, 2002Publication date: May 22, 2003Inventors: Philip Maurice Higgs, Charles William Stratford Presant
