Patent number: 10125522Abstract: A lockset is actuable by pivoting a handle about a longitudinal axis of the lockset by rotating the handle and by pivoting the handle about an axis transverse to the lockset axis, such as by pushing or pulling. The lockset includes an inside handle and an outside handle, each associated with an independent mechanism, each of which can independently actuate the lockset. A locking mechanism prevents actuation of a first one of the independent handle mechanisms without affecting operation of the other handle mechanism. Upon actuation of the other handle mechanism, a retractor engages a surface of the locking mechanism and removes it from engagement with the first locking mechanism. An adjustment ring has a first configuration that centers the lockset in a door having a first standard thickness and a second configuration that centers the lockset in a door having a second standard thickness.Type: GrantFiled: August 17, 2016Date of Patent: November 13, 2018Assignee: Hampton Products International CorporationInventors: Xin Ben Ou, Xin Min Ou, Han Gui Xiao, Zhi Man Yuan, Shi Hao Chen, Guo Hua Liu

Patent number: 7222890Abstract: Disclosed is a door latch assembly having an integrated means to accommodate multiple backset dimension requirements while facilitating the backset adjustment selection to be done in an easy and convenient manner. The multiple backset latch has as primary components a housing body assembly and a latch bolt housing assembly. The latch bolt housing assembly includes a housing body channel member, a cam support plate member, a bolt retractor member, a cam lever member, a positioning spring member, and a housing body plate. The latch bolt housing assembly further includes a latch bolt head. The housing body channel has an oval aperture corresponding to accept the cam lever member. The oval aperture has multiple radii sufficient to accommodate lateral movement to provide 60 mm (2? inches) and 70 mm (2¾ inches) backset.Type: GrantFiled: January 20, 2005Date of Patent: May 29, 2007Inventor: Zhi Man Yuan
