Abstract: A contact-minimizing door opening and closing system for a door has a handle including a shaft with an endplate disposed on the shaft opposite the handle and a latch bolt including a pin positioned to contact the endplate. The pin prevents movement of the handle when the latch bolt is extended from a lock housing, and allows movement of the handle when the latch bolt is retracted into the lock housing. An engaging and disengaging mechanism couples the handle to a locking pin such that movement of the handle is configured to operate the engaging and disengaging mechanism to lock the door.

Abstract: A lock defining a rotating axis and for being installed on a door includes a first handle set, a second handle set, a transmission element and a latch mechanism. The first handle set is disposed on a side of the door and includes a first handle and a first tubular element. The second handle set is disposed on another side of the door and includes a second handle, a cylindrical element, a movable element and a second tubular element. The second tubular element is independent from the first tubular element. The transmission element has a first end connected to the first handle set and a second end connected to the movable element. The latch mechanism is disposed between the first handle set and the second handle set and includes a latch tongue driven by the first tubular element or the second tubular element.

Abstract: A latch assembly is provided where the latch is moveable to open and close a door by operation of a dead lock assembly that blocks or unblocks movement of a bolt. In a blocked state, a blocking cartridge of the dead lock assembly is prevented from inward movement, blocking inward movement of the bolt. Turning a door knob or door handle causes a spindle extending through the dead lock assembly to move locking bars of the dead locking assembly, the locking bars moving further apart to permit the blocking cartridge to slide there between and move inwardly into the latch housing. The bolt can now move inward by force of the doorjamb upon the bolt in order to clear the doorjamb when opening and closing the door.

Abstract: A latching system includes a guide body, and a latch rod slidably retained by the guide body. Latch assemblies fixed to the latch rod, are spaced apart from one another, and independently biased to a latched position. A first rod-biasing spring is coaxial with the latch rod and disposed between the guide body and a first latch assembly. The first rod-biasing spring biases the latch rod to a rest position corresponding with a latched position of the latch assemblies. Multiple catches are secured at a spacing equal to a spacing of the latch assemblies on the latch rod such that the latch assemblies latch to the catches independently of one another. A force on the latch rod against the first rod-biasing spring moves the latch rod along the longitudinal axis of the latch rod from a rest position to an actuated position and unlatches the latch assemblies simultaneously.

Abstract: A latching system for releasably securing a first structure relative to a second structure. The latching system includes a latch assembly coupled to the first structure and a keeper assembly coupled to the second structure. The latch assembly is selectively engageable with the keeper assembly to hold the first structure against movement relative to the second structure.

Abstract: A tie bar and guide assembly for casement windows having a roll form tie bar that snaps on to the tie bar guide without extending through it. The tie bar has locating openings that engage tabs on the tie bar guide to locate and secure the guide prior to installation. The tabs are depressed and disengaged when fasteners are used to secure the tie bar assembly to the window frame. The tie bar can include rivet locking points located close to the top and bottom of the tie bar to provide better security and increased stability for preventing water and air infiltration. The rivet locking points can be adjustable to optimize the fit of the window sash within the frame. The snap-on design reduces the overall height of the tie bar assembly thereby enabling a closer fit of the sash within the frame and reducing the required width of the window frame needed to accommodate the locking mechanism.

A closure device is distinguished by the fact that the lock element is arranged in such a way that, preferably under the action of a spring, in a first position with respect to the mating piece it is or can be moved into a locking position and, in a second position, it reaches a position and/or a state without any blocking action.

Abstract: A conventional safe proper becomes useless when unable to be locked or unlocked, thereby causing a waste of resources. Locks capable of being locked/unlocked are provided to unfasten a common fastening member, so as to open a door or lid from the body, allow each lock to be freely mounted on and dismounted from a lock mounting portion, and dispose a false lock on each lock. An operating means of locking/unlocking any one of the locks is provided to enable persistent use of a common latch disposed at an identity opening of a safe proper.

Abstract: Electromechanical lock utilizing magnetic field forces. An actuator is moved (1202) from a locked position (260) to an open position (400) by electric power. In the locked position (260), a permanent magnet arrangement directs (1204) a near magnetic field to block an access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1206) the near magnetic field towards a far magnetic break-in field originating from outside of the electromechanical lock. In the open position (400), the permanent magnet arrangement directs (1208) a reversed near magnetic field to release the access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1210) the reversed near magnetic field towards the far magnetic break-in field.

Abstract: A security device for a door in a doorway. The device includes a floor-carriable portion and a door-carriable portion magnetically co-operable with the floor-carriable portion to stop the door opening past a communication position at which the door is positioned to guard the doorway and ajar to enable the communication via the doorway. At least one of the floor-carriable portion and the door-carriable portion is reconfigurable to allow the door to open past the communication position.

Abstract: A magnetic latch for fastening a closure member to a support. The magnetic latch comprises a latch bolt assembly comprising: a first elongated housing configured to be mounted with its rear side facing either the closure member or the support; a second housing connected to and positioned underneath the first housing, the second housing being rotatable with respect to the first housing around the vertical direction between a first rotational position in which the latch bolt assembly is operable for a right-handed closure member and a second rotational position in which the latch bolt assembly is operable for a left-handed closure member; and a latch bolt mounted in the second housing. The different rotational positions of the second housing allow using a horizontally moveable latch bolt while retaining a symmetrical placement on the closure system irrespective of the handedness of the closure member.
