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
