Patent number: 8210581Abstract: A door handle assembly for attachment to an escutcheon, the assembly comprising a door handle, wear washer, spindle nut, spindle nut retainer, and shaft retainer. The door handle has a hub, externally threaded for engagement with the internal threads of the spindle nut, with a central hole and axial slots engaging locking tabs of the spindle nut retainer. The wear washer is inserted over the hub between the inside surface of the escutcheon and the spindle nut. The spindle nut is adjusted on the hub until the proper fit and feel is achieved. The spindle nut retainer is placed over the spindle nut to lock it in position, and a shaft retainer is placed over the spindle nut retainer to secure it. The spindle nut provides more contact surface area with the underlying wear washer, reducing cyclic wear, increasing product life, reliability and security.Type: GrantFiled: April 8, 2009Date of Patent: July 3, 2012Assignee: Newfrey, LLCInventor: Randy S.

Patent number: 8113021Abstract: A door lock with an improved structure is disclosed. It has a turning device that includes a positioning base. The positioning base is mounted with a circular spacer with a lock control device therein. A connecting shaft for driving the lock control device is provided with a limiting element that has a protruded stopping part at its end. The lock has a lock core whose one end allows the insertion and turning of a key. Its other end is connected with the connecting shaft and has grooves, so that the stopping part of the limiting element blocks the lock core when the door is locked.Type: GrantFiled: October 10, 2008Date of Patent: February 14, 2012Assignee: Imperial (Asia) LimitedInventor: Miao-Hsueh Tsai

Patent number: 8070194Abstract: The invention relates to an installing mechanism and its deinstalling tool for a control turning handle (150) of a lock on an actuating rod (17) comprising two assemblies (E1, E2) that interact via a bayonet-type assembly by an axial engagement in the direction of the leaf then a rotation in a circular arc branch, in a second direction opposite the first direction around the axis of the rod, of the second assembly (E2) on the first set (E1), characterized in that each circular arc branch comprises an engagement limit stop upon which an associated stub rests, and a retractable stop for rotationally blocking the associated stub in the circular arc branch. The invention is particularly for use in a hygienic handle.Type: GrantFiled: November 6, 2006Date of Patent: December 6, 2011Assignee: CyclopeInventor: Richard Houis

Patent number: 8052178Abstract: Disclosed is a temporary door lock assembly. The assembly is formed from five major components: a rosette; a bolt; a barrel; a locking arm; and an inside plate. These components are lockingly interconnected without any fasteners or the use of any tools to form a door lock. The lock can be temporarily secured within the lock opening and barrel of a door frame during residential or commercial construction to thereby delay the need to install more complicated and expensive permanent locks.Type: GrantFiled: July 17, 2007Date of Patent: November 8, 2011Assignee: Templok, Inc.Inventors: Hugh MacDonald, Carl Christopher Sutherland

Patent number: 8011703Abstract: 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.Type: GrantFiled: February 8, 2005Date of Patent: September 6, 2011Assignee: Assa Abloy Australia Pty LimitedInventors: Donald John Newman, Robert John Watson
