A cylinder lock capable of normal unlocking operation by an authorized key to a locking mechanism which has been illegally operated by an unauthorized key or the like, the cylinder lock comprising an engaging portion (16,23) that engages a rotor (2) in the rotational direction only when the cylinder moves toward the unlocking member (5) is disposed to a cylinder to engage the rotor (2) and the cylinder thereby rotating the rotor (2) upon subsequent insertion of an authorized key to connect the rotor (2) and the connection member (5) thereby enabling normal unlocking operation.

A lock with a plug (2) removable from a housing (16) is disclosed. The plug (2) includes a restraining member (46) and a protrusion (40) which engages a concentric groove (52) formed into a plug housing. Intersecting the concentric groove is a longitudinal groove (50). Upon inserting an operation key the restraining member is forced into engagement with the concentric groove thereby preventing plug removal even upon alignment of the protrusion with the longitudinal groove (50). Upon inserting a removal key (42) the restraining member (46) is disengaged from the concentric groove so that the plug may be withdrawn upon rotationally aligning the protrusion (40) with the longitudinal groove (50). In this manner a simple and compact removable plug is provided to aid rapid lock re-keying.
摘要:
A removable core cylinder lock with a cylinder lock casing and a removable cylinder lock core (20) inserted into the casing. The lock core has an upper massive part (22) with a row (25) of holes for accomodating locking tumblers (26, 66) and a lower part (23) defining a cylindrical bore (24), in which a cylindrical, rotatable key plug (60) is located. The lower part (23) defining the cylinder bore (24) of the cylinder lock core (20) is partially cut away so as to form an axially elongated chamber (30) accomodating a transversely movable retainer member (40) and leaving a continuous lower wall portion (23a). The retainer member has an axial length, which corresponds to at least half of the axial length of the row (25) of holes in the upper massive part, and a limited circumferential extension, which is substantially supplementary to the continuous lower wall portion so as to define said cylindrical bore (24).
摘要:
A removable core cylinder lock, comprising a casing (10), a lock core (20) with a rotatable key plug (30) in a cylindrical bore (23) and retaining means adapted to releasably retain the lock core in an inserted position in the casing. The casing has two lugs (14, 15) extending radially inwards and being separated transversely from each other, whereas the lock core has two corresponding recesses (27, 28) on both sides of a central, rear portion, whereby the lock core can be fully inserted into said casing. The two lugs are provided with means for fastening the casing to an object.
摘要:
The invention relates to a casement closure device for a door or casement, especially of switch cabinets or the like, comprising a housing (10) which can be fixed on the door leaf or on the cabinet body. The closure device also comprises a key-operated lock cylinder (13) which is arranged in said housing, and a locking tongue (19) which can turn between an unlocking position and a locking position. The aim of the invention is to produce a casement closure device exhibiting a tightening torque which is as large as possible. To this end, the lock cylinder (13) is uncoupled from the locking tongue (19), is locked in the housing (10) when the key is removed, and can be removed from the housing (10) when the key is inserted and moved to the unblocking position. In addition, the locking tongue (19) which is held on the housing (10) comprises an actuation opening (20) for engaging an actuating means which can be inserted in the housing channel (12) in a positive locking manner, said channel being free when the lock cylinder (13) is removed from the housing (10).

摘要:
A lock mechanism has a cylindrical housing (11) with an axial bore (15) therethrough, and a key-controlled core (50) rotatable within the bore (15) between locked and unlocked conditions and removable from and installable in the bore (15) in the unlocked condition. The core (50) has a plug (55) at its rear end which is mateably engageable in a socket (40) on the front face of a shifter (30), for rotating the shifter (30) within the bore (15) in response to rotation of the core (50), and thereby operating a latch member (48) coupled to the shifter (30). A radial tab (25) on the housing is receivable in an arcuate groove (45) formed in the outer surface of the shifter (30) for limiting rotation of the shifter (30) to facilitate retention of the shifter (30) in the single rotational orientation upon removal of the core (50) from the housing. An O-ring (33) on the shifter (30) frictionally inhibits rotation thereof.
