Publication number: 20150308157Abstract: A method of mounting an electronic door lock on a door includes: a manual operation to rotate a protrusion of a rotational actuator to initially press a switch; and an operating procedure implemented by the electronic lock for determining a correct mounting direction of the electronic door lock. The operating procedure includes controlling, in response to a signal sent by the switch that is initially pressed, a driving unit to rotate the protrusion in a direction from the initially pressed switch to the other initially un-pressed switch and to drive a latch to move from an unlatched position toward a latched position, followed by stopping and subsequently controlling the driving unit to rotate the protrusion in a reverse direction and to drive the latch to move toward the unlatched position.Type: ApplicationFiled: April 21, 2015Publication date: October 29, 2015Applicant: Tong Lung Metal Industry Co., LTDInventors: Chen-Ming Lin, Tung-Yi Ho

Patent number: 8746760Abstract: In a handle-returning device of a cylinder lock assembly, a support base has an inner annular flange and an axial spring-retaining lug. A rotation driver has an inner tubular wall extending into the inner annular flange of the support base, and a spring driving element. A torsion spring is disposed around the inner annular flange and between the support base and the rotation driver, and has a spring leg abutting the spring-retaining lug and the spring driving element. A rotary plate abuts the support base opposite to the rotation driver, and has an engaging part engaging a tongue projecting from the rotation driver. A reinforced structure is thus provided to oppose high torsional stresses produced upon rotation of a lever handle.Type: GrantFiled: March 15, 2012Date of Patent: June 10, 2014Assignee: Tong Lung Metal Industry Co., Ltd.Inventors: Po-Yang Chen, Kai-Ting Tung, Yu-Ting Huang, Chia-Min Sun, Song-Gen Shyu, Ching-Chuan Kuo

Patent number: 8584495Abstract: An exchangeable cylinder lock includes a plug shell connected to a pin chest. A locking pin is disposed in a radial pin hole in the pin chest and is biased to protrude from an aperture in a cover plate and to engage a lock housing. The locking pin is depressable to retract for disengaging from the lock housing. A locking ring is disposed around the plug proximate to the locking pin, and has at least one indentation. When the plug is rotated using a right key, the locking ring can be rotated to align the indentation with the locking pin so as to permit depression of the locking pin, or to move the indentation away from the locking pin so as to prevent depression of the locking pin.Type: GrantFiled: February 9, 2012Date of Patent: November 19, 2013Assignee: Tong Lung Metal Industry Co., Ltd.Inventors: Ming-Shyang Chiou, Kuang-I Liao

Patent number: 8490445Abstract: A door lock includes a first driven wheel connected drivenly to a motor and having two resilient driving elements, and a second driven wheel connected drivenly to a rotary handle and the first driven wheel. The second driven wheel has a driven element disposed between and driven by the driving elements so that the second driven wheel moves to a first or second position to place a latch bolt in a latching or unlatching position. When the latch bolt is jammed, the second driven wheel is inoperative. However, as the driving elements are resilient, the first driven wheel can continue its rotation without being obstructed.Type: GrantFiled: August 12, 2010Date of Patent: July 23, 2013Assignee: Tong Lung Metal Industry Co., Ltd.Inventors: Ming-Shyang Chiou, Chia-Min Sun, Yu-Ting Huang, Yu-Le Lin
