Patent number: 11060330Abstract: A lock for an access point such as a window includes a dual-action locking mechanism with a locking unit and a blocker. The locking unit is movable between a locking position and an unlocking position. The blocker blocks movement of the locking unit when the blocker is in a blocking position, and permits movement of the locking unit when the blocker is in an unblocking position. The lock may capture an insert attached to a tether to permit partial opening of a window while the unit is locked.Type: GrantFiled: May 15, 2018Date of Patent: July 13, 2021Assignee: Elbee Pty Ltd.Inventor: Andrew Marsden

Patent number: 11021894Abstract: In general, the present invention is incorporated in a cam lock housing that is securable relative to a drawer or door. Coupled to the cam lock housing is an actuator package. The actuator package of this exemplary cam lock system can include a retractable geared plate or tongue, a micro gear motor, a controller, and a power system. In operation, the drive gear/pinion causes lateral displacement of tongue towards or away from a latch in order to lock or unlock the item. As such, a medicine cabinet (or similar), can be remotely locked or unlocked. Alternatively, rotation of a physical key within the cam lock rotates the cam lock housing and the tongue towards or away from a latch so that the cam lock can also be operated manually.Type: GrantFiled: November 13, 2018Date of Patent: June 1, 2021Assignee: Smart Armor Protected, LLCInventors: Justin Zastrow, Ira Hayes, William Birgen

Patent number: 8746022Abstract: A pull-up latch mechanism includes a stator (2) with an inner open channel (20), a cap (10) attached to a cylinder (1) lodged into the open channel (20) of the stator (2), a shaft (8) provided with a latching pawl, and a control system connecting the shaft (8) to the cylinder. The control system is adapted for generating a first movement of rotation of the cylinder, a movement of the shaft (8) away from the cylinder in the direction of the longitudinal axis, for generating a second movement of rotation of the cylinder, and a movement of the shaft towards the cylinder in the direction of a central axis.Type: GrantFiled: November 3, 2011Date of Patent: June 10, 2014Assignee: Euro-Locks S.A.Inventors: Sébastien François, Christophe Grandjean

Patent number: 8651538Abstract: The invention relates to a lock comprising a lockable knob, formed by a closure tongue (1) non-rotatably mounted on the shaft of a cylinder (2) which rotates in a casing (3) under the action of a knob (4). The knob (4) is mounted on the cylinder (2) and casing (3) such that it can move linearly between two end positions, namely an operating position and a locked position. The casing (3) and the knob (4) include at least two geometrically arranged linear guides (33, 43) which, during the linear movement of the knob (4), are engaged with, or released from one another. In addition, the cylinder (2) and the knob (4) include radial openings (20, 40) which are positioned coaxially in the locked position and offset axially in the operating position. The cylinder (2) and the casing (3) include geometrically arranged cams (22, 32) which limit the rotational movement of the cylinder (2) in the casing (3) between the tongue (1) -opening and -closing positions.Type: GrantFiled: May 19, 2009Date of Patent: February 18, 2014Assignee: Ojmar, S.A.Inventor: Ricardo Sendin Martin

Patent number: 7441427Abstract: A latch has a bushing which has at least one bushing projection or means for preventing insertion of an unauthorized tool to rotate a latch actuator of the latch. Only a key having an outer key recess which can mate with bushing projection on the bushing permits insertion of the key. The cap subassembly of the latch is provided with projections which are of a size and so positioned as to correspond with the internal recesses of the key so as to allow the cap subassembly to enter into the bore of the key and permit a mating engagement of internal recesses on the key and projections on the cap subassembly. Because cap portion rotates freely on top of the cap subassembly which is the part of the cap driven by the key, the arrangement makes it impossible, or at least very difficult, to rotate the shaft and in turn the pawl by means of a tool which rotates the cap portion.Type: GrantFiled: September 14, 2007Date of Patent: October 28, 2008Assignee: Southco, Inc.Inventor: James H. Vickers

Patent number: 7272963Abstract: A gate latch including a bolt portion, a sleeve portion and a channel bolt. The sleeve portion is mounted on a generally U-shaped clamp assembly that is adapted to fit around tubular gate members. The sleeve portion further includes a receiving notch and a padlock portion. The padlock portion is adapted to receive a standard padlock and to surround the shackle of the padlock so as to deter attempts to attack the shackle with cutting tools. The bolt portion includes a C-shaped channel adapted to be secured around tubular gate members and a sleeve in which the channel bolt slides. The channel bolt generally includes an elongate channel, an adjustable stop, a dead stop, a handle and a locking notch.Type: GrantFiled: September 13, 2004Date of Patent: September 25, 2007Assignee: Cargo Protectors, Inc.Inventors: Avron S. Rosenberg, Ben Bricko

Patent number: 6843082Abstract: A key operated latch includes a housing which supports a lock plug, a motion control sleeve, and a sleeve-like cam therein. The cam rotates with the lock plug, while the motion control sleeve is stationary. The cam has at least one cam slot, and the motion control sleeve has at least one motion control slot. A shaft extends outward from the housing and has at least one projection which is engaged with both the cam slot and the motion control slot. The cam slot and the motion control slot are configured such that rotation of the lock plug imparts a sequence of rotational and axial movements to the shaft. A latching member attached to the shaft, moves between a latched position and an unlatched position in a sequence of axial and rotational motions in order to selectively secure a door, panel, or the like in the closed position.Type: GrantFiled: September 3, 2003Date of Patent: January 18, 2005Assignee: Southco, Inc.Inventor: James H.

Patent number: 6568226Abstract: A rotating-lock closure is provided with a traction unit, wherein the closure comprises a housing having a first bearing area for the receiving head of a key to be inserted as well as a second bearing area for the rotating-lock driving support that supports said rotating lock and is mounted so as to be capable of axial and sliding displacement and of rotation in the second bearing area. A shaft having a rounded cross section and extending from the key receiving head protrudes relative to the rotating-lock driving support and has a transverse opening at its protruding end for receiving a pin. A cam track, on which the pin is guided against the force of a spring, is formed by the side of the lock facing away from the housing.Type: GrantFiled: August 31, 2001Date of Patent: May 27, 2003Inventor: Dieter Ramsauer

Patent number: 5152161Abstract: A cam lock having an adjustable cam bolt. The cam lock has a tubular lock case, a tumbler, a shaft, a spring, and a cam bolt. The tubular lock case has an inner flange which divides the lock case into a first portion and a second portion which is formed with a restricting element. The tumbler is received in the first portion. The shaft is rotated by the tumbler and extends into the second portion. The spring is disposed around the shaft within the second portion. The cam bolt is mounted on the shaft by threaded engagement so as to compress the spring and has an arc-like cutoff beyond which the restricting element extends.Type: GrantFiled: January 21, 1992Date of Patent: October 6, 1992Assignees: ABA Locks Manufacturer Co., Ltd., Jin Tay Industries Co., Ltd.Inventor: Miko Lee

Patent number: 5076080Abstract: A hatch latch with a peripheral top surface adapted to fit through an opening in a hatch has a rotatable axial shaft with a latch member toward its lower end, the shaft being partially enclosed in an outer housing and having a central cavity at its upper end surrounded by a groove in the peripheral top surface which makes the hatch latch waterproof by draining water to the periphery by one or more channels leading to an edge of the peripheral top surface. The cavity is adapted to contain a locking device for locking a hatch that needs to be both latched and locked or a plug to fill the top of the cavity when the hatch requires only latching. A bail, D-ring or the like is used to raise and lower the shaft between secured and latched positions and, to rotate the shaft between latched and unlatched positions.Type: GrantFiled: February 13, 1991Date of Patent: December 31, 1991Inventors: Mac Fuss, James B. Fuss
