Abstract
A handle assembly has a handle, a handle spigot to which the handle is attached, a biasing member to bias the handle to a naturally closed position, an operating plate which is rotatable by the handle spigot, a mounting stock, and a housing, the spigot, the biasing member, operating plate and a majority of the mounting stock being positioned within the housing, the mounting stock being securable to the housing to hold all the components within the housing. In this manner, the handle assembly can be made as a “complete” unit with all the internal components being in position and with the handle being rotatably attached relative to the housing. Thus, no separate rose is required. Another advantage is that the unit can be assembled using a substantially concealed fixing arrangement to improve security and also to improve the aesthetic appeal of the assembly.
