Patent number: 11692641Abstract: The present invention is an improved fluid valve control device which attaches to a pre-existing and pre-installed hex head valve. The valve control device has at least one lever which can be used to turn the valve on or off. This device can be attached to a manifold assembly that has a valve which typically requires a tool to control so that it eliminates the need for a separate tool being used to turn the valve on or off after installation at relatively low cost.Type: GrantFiled: November 15, 2021Date of Patent: July 4, 2023Inventor: Jeffrey Bailey

Patent number: 9062475Abstract: A roseless trim for a mortise or tubular lock includes through bolts on a bolt circle of less than one inch (25.4 mm). Spindle hubs with a curved slot allow at least one of the through bolts to pass through the spindle hubs. A tubular lock embodiment uses arms with a cutout. The arms function as through bolts when screws attach the arms to mounting plates on opposite sides of the door. Each handle is attached to a corresponding handle base with a bushing. The handle base and small diameter bolt circle cooperate to provide the appearance that the handle extends directly into the door without a rose, escutcheon or any other attachment structure at the base of the handle.Type: GrantFiled: September 4, 2013Date of Patent: June 23, 2015Assignee: Sargent Manufacturing CompanyInventors: Donald T.

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: 7753417Abstract: A locking/unlocking device usable with a door operator having a tapered shaft including a first element possessing a surface with a recess. A second element also includes a surface such that a fastener removably holds the first element to the second element to form a unit. The unit includes an aperture formed by the recess to at least partially circumscribe the tapered shaft of the door opener. A moveable foot located on the unit is driven against the door to allow the door operator to be positioned between a locked and unlocked orientation.Type: GrantFiled: August 29, 2008Date of Patent: July 13, 2010Inventor: Roger Koughan

Patent number: 7581421Abstract: A door lock assembly includes a transverse retaining plate disposed inside a spindle tube and having a stabilizing part and a retaining tongue projecting into a retention slot in a handle. A support structure is disposed within the handle oppositely of the retention slot and has a support part extending radially into the spindle tube. When the door lock assembly is in a locking state and when the retaining tongue in the retention slot is pressed externally, one of two diametrically opposite edges of a tailpiece of a key plug abuts against the support part, and the other one of the edges abuts against the stabilizing part of the retaining plate to restrict the retaining tongue from moving away from the retention slot, thereby preventing undesirable removal of the handle from the door lock assembly.Type: GrantFiled: September 20, 2007Date of Patent: September 1, 2009Assignee: Tong Lung Metal Industry Co., LtdInventors: Lan-Kun Don, Po-Yang Chen, Ching-Chuan Kuo

Patent number: 6681605Abstract: A tubular doorknob includes an inside bracket, an outside bracket and adjustment devices. The outside bracket has two connecting wings, two outside passages, two outside screw holes and an outside adjustment device. The connecting wings protrude from diametrically opposite sides of the outside bracket. The outside passages are defined through the connecting wings. The outside screw holes are defined through the outside bracket and communicate with the outside passages. The outside adjustment device has two sliding blocks and two adjustment screws. The sliding blocks are slidably mounted in the outside passages. The adjustment screws are screwed into the outside screw holes to push the sliding blocks to abut a surface in a doorknob hole in the door. The inside bracket has a configuration similar the outside adjustment device. The extended adjustment devices firmly hold the tubular doorknob in the doorknob hole.Type: GrantFiled: May 9, 2003Date of Patent: January 27, 2004Assignee: Taiwan Fu Hsing Industrial Co., Ltd.Inventor: Chao-Ming Huang

Patent number: 6532629Abstract: A quick install dummy doorknob or lever comprises an exterior knob sub-assembly, an interior rose liner coupled to the exterior knob assembly, a knob catch, a retainer spring, and an interior knob. The knob catch is disposed inside the interior rose liner and includes a tooth for engaging the interior knob. The interior rose liner engages a pair of screws extending from the exterior knob sub-assembly. Rotation of the interior rose liner relative to the screws places the screws into retaining apertures in the interior liner, whereupon the screws can be tightened to hold the interior rose liner in position. The interior knob is inserted into a recess formed in the interior rose liner and engages the tooth on the knob catch through a slot formed in the recess.Type: GrantFiled: January 5, 2001Date of Patent: March 18, 2003Assignee: Newfrey LLCInventor: Steven Armstrong
