The first fastening member (11) comprises: a casing (17) equipped with an operating opening (18); a housing (19) for a cylinder (101) of the lock (100) and equipped with a locking device (21) for blocking the cylinder (101); a closing element (22) movable with respect to the housing (19) between an open position and a closed position in contrast with an elastic device (23).
In the closed position of the closing element (22) it is interposed between the operating position (18) and the locking device (21) and in the open position the closing element (22) protrudes from the first abutment face (12) and it is not interposed between the operating opening (18) and the locking device (21).

A lock mechanism includes a first mounting plate, a second mounting plate, a restricting plate, a fixing base, at least one first fixing element and at least one second fixing element. The first mounting plate and the restricting plate are mounted on one side of a door, and the second mounting plate and the fixing base are mounted on the other side of the door. The first fixing element is penetrated through the restricting plate in a direction from the restricting plate toward the second mounting plate. The second fixing element is penetrated through the fixing base in a direction from the fixing base toward the first mounting plate. The fixing base and a lock cylinder disposed on the fixing base can be disassembled and replaced by removing the second fixing element such that dismantling the whole lock mechanism is not necessary.

A lock and method for locking wherein the lock includes a cylindrical housing that houses at least a replaceable battery, a lock mechanism, an electronic circuit powered by the replaceable battery, the electronic circuit being configured to authenticate a user and electro-mechanically actuate the lock mechanism of the lock responsive to being activated, and a rotor coupled to the lock mechanism of the lock, the rotor being powered by the replaceable battery and configured to situate the lock mechanism based on a lock state of the lock, and a handle situated outside the cylindrical housing on a front side of the cylindrical housing, the handle being coupled to the lock mechanism, the handle being configured to activate the lock responsive to the user moving the handle.

Disclosed is a device of wireless controlling a lock, which comprises a main body, the main body comprises: an open unit (1010), one end of the open unit (1010) is inserted to a key hole at the side of the door lock faced to the locked space and is disposed at an initial position; the initial position is a position when the open unit is inserted to the key hole; a driving unit (1020), the driving unit (1020) is linked to the open unit (10100) to drive the insert end of the open unit (1010) to rotate in the key hole; a start unit, the start unit is wireless connected to the driving unit, the start unit transmits control signal to make the driving unit drive the insert end of the open unit to rotate. The present invention further discloses a method of preventing unlocking from outer side

Apparatus for unlocking and locking a lock (1) enabling access to protected areas. The apparatus comprising a housing (5) with a housing interior (16). A rotatable shaft (18) with an axis (20). The rotatable shaft (18) is in fixed non-rotatable connection with the housing (5) and is in operative coaxial connection with a rotatable member (6) that is rotatable within a body (4) of the lock (1) about the axis (20) to change the lock (1) between the locked condition and the unlocked condition. The housing (5) and the shaft (18) are in operatively supported connection with the body (4) of the lock (1). A motor (22) extends in the housing interior (16), is in operative connection with the shaft (18), and is operative to cause rotation of the shaft (18) within the body (4) of the lock (1).

An exemplary closure assembly includes a swinging barrier, a pushbar assembly mounted to a first side of the barrier, a remote trim assembly mounted to a second side of the barrier, and a transmission assembly that extends at least partially through the barrier and couples remote trim assembly and the pushbar assembly. The pushbar assembly includes a latchbolt and a pushbar operable to retract the latchbolt. The remote trim includes a handle that is operably coupled with the latchbolt via the transmission assembly such that the handle is operable to retract the latchbolt. The handle is positioned above the pushbar such that a vertical offset distance is defined therebetween. The offset distance is selected such that a user having a height within a selected range of heights is able to actuate the pushbar assembly, but cannot actuate the trim assembly.

A lock mechanism includes a first mounting plate, a second mounting plate, a restricting plate, a fixing base, at least one first fixing element and at least one second fixing element. The first mounting plate and the restricting plate are mounted on one side of a door, and the second mounting plate and the fixing base are mounted on the other side of the door. The first fixing element is penetrated through the restricting plate in a direction from the restricting plate toward the second mounting plate. The second fixing element is penetrated through the fixing base in a direction from the fixing base toward the first mounting plate. The fixing base and a lock cylinder disposed on the fixing base can be disassembled and replaced by removing the second fixing element such that dismantling the whole lock mechanism is not necessary.

The invention relates to the field of locks, and discloses a locking device comprising: a latch fixed on an object to be locked for engaging with a bore of a strike, the latch having a bolt configured to lock the object by moving approaching the bore; a spindle, one end of which being detachably connected with the latch for driving the bolt to move towards or away from the bore; and a rotary assembly disposed at an other end of the spindle, a spindle driving means being provided at one end of the rotary assembly adjacent to the spindle and engaged with the other end of the spindle under an external torque to drive the spindle to rotate; wherein the rotary assembly drives the spindle to rotate via the spindle driving means under the external torque, and the spindle drives the bolt to move approaching the bore to realize locking.
