Patent number: 7962998Abstract: A roller support assembly is used to support sliding doors, windows or the like. The assembly includes a housing member having spaced apart side walls and interconnecting transverse walls defining a roller receiving zone for receiving and operationally mounting a roller assembly. The roller assembly has a roller body with a rolling peripheral rim and a shaft whereby the roller body is rotatable relative to the shaft having short stub axle parts. The housing side walls including openings that are fully enclosed by the side walls into which the short stub axle parts fit. The housing side walls further include projecting elements extending inwardly from an inner surface of a housing side wall to cooperate with the corresponding roller body side wall surfaces to spay the housing side walls apart as the roller assembly is moved into the roller receiving zone to locate the stub axle parts in the openings.Type: GrantFiled: September 24, 2007Date of Patent: June 21, 2011Assignee: Anthony Innovations Pty, LtdInventors: Nigel Proctor, Paolo Lazzarin, Derek Jefferson
