摘要:
A cylindrical lock with tumbler and driver pins opened or closed by a cylindrical key in which a cylindrical plug is provided with one row or several rows of ".phi."-shaped tumbler pins and the lock body is provided with corresponding driver pins of diversified shapes in equivalent rows. When the lock is closed, the driver pins brake the cylindrical plug at the lock body and thus cannot be rotated. In order to open the lock, the cylindrical key bar is inserted in the key hole of the plug. The key bar is formed with grooves of suitable angle. When the cylindrical key bar is rotated in the key hole, the grooves on the key bar will back up the ".phi."-shaped tumbler pins to the periphery of the plug while pushing the driver pins from the plug into said lock body to make the plug free from said lock body. The cylindrical key bar with special designed angled grooves will apply pressure to the ".phi."-shaped tumbler pins engaging with said plug so as to actuate the lock latch. Outside the plug, lock body and the diversified driver and tumbler pins of said lock, one set of protecting ring and protecting plate is provided to hide the plug within said lock body to make no forcible points therein so as to reduce the possibility of opening by the thief.

A barrel key apparatus wherein there is a handle section attached to a cylindrically shaped tubular section, within the cylindrically shaped tubular section there is located a plurality of spaced apart elongated grooves which are of the same length and extend from the outer free end of the tubular section. Within each of the grooves there may be selectively located one of a group of different length push pins. At the inner end of each groove is located an opening extending to the interior of the tubular section. The push pin includes an attaching means comprising a plurality of spaced apart annular ridges successively connected together along a single longitudinal axis. The attaching means is to be inserted within the opening at the end of the groove with the under surface configuration of the push pin matingly cooperating within the groove and the outer surface of the push pin cooperating with the outer surface of the tubular section to form a flush, smoothly contoured surface. The attaching means is such that it prevents withdrawal of the push pin once it has been inserted without destroying or damaging the pin.

The present invention is to provide a structure of key part having hideable lock cylinder, which comprises a base unit having an end able to be fixed on an object body; a lock cylinder unit mounted at the other end of the base unit and provided with a cylinder column at an end thereof; and a key unit provided with a locking piece at a side edge of an end thereof, having the other end pivoted on the lock cylinder unit at a position near the cylinder column, and having a groove axially provided thereon for accommodating the cylinder column; whereby the cylinder column can be inserted into a lock adjusting slot of a handcuff, or can be hidden in the key unit while not in use. Thus, a user needs not to worry that pocket of his or her clothing will be hooked and damaged by the cylinder column.

A locking device includes a lock and a key. The lock includes a housing, a cylindrical core inserted into and rotatable relative to the housing, and a limiting member that is mounted movably between the housing and the cylindrical core to permit or prevent the relative rotation between the housing and the cylindrical core and that extends into a helical keyway formed in the cylindrical core. The key has a helical blade capable of being inserted into the helical keyway to access the limiting member, so as to move the limiting member to permit the relative rotation between the cylindrical core and the housing.

An unlocking device includes a casing mounted to a side of a lock. A movable body is movably received in the casing along a first axis and has an opening. The lock has a keyhole in an extent of the opening. A key receiving seat is movable along a second axis perpendicular to the first axis between a first position received in the movable body and a second position at least partially outside of the movable body. A linking rod is extended into the movable seat. A key can be placed into a key receiving hole of the key receiving seat in the second position and then moved into the movable body to engage with the linking rod when the key receiving seat moves to the first position. The key is movable into the keyhole by moving the linking rod along the first axis and is rotatable for a locking or unlocking operation.

A key includes a shank having at least one groove and at least one recess, and the at least one groove has different lengths. At least one magnetic member is received in the at least one recess and a number of the at least one magnetic member is not more than a number of the at least one recess. The arrangements of the at least one recess, the at least one groove and the at least one magnetic member have multiple options. The magnetic members are located in different recesses and the magnetic poles of the magnetic members are arranged in different ways. The key is difficult to be copied and has higher safety standards.

A key and a lock cylinder (10) combination including a key and a lock cylinder having a housing and a plug. The key (25) includes a blade that has a first pin groove (210) on a first lateral side defining a first pin surface, and a second pin groove (215) on the first lateral side defining—a second pin surface. The lock cylinder also includes an auxiliary pin (115) with a first projection (135) defining a first engagement surface engageable by the first pin surface when the key is inserted into the key slot to move the auxiliary pin to a withdrawn position to allow rotation of the plug relative to the housing, and a second projection (140) defining a second engagement surface engageable by the second pin surface when the key is removed from the key slot to move the auxiliary pin to a projecting position to prevent rotation of the plug relative to the housing.
摘要:
A lock and key combination is disclosed, offering a large number of codes. The combination includes a lock (200) of the kind comprising a housing having a cylindrical bore, a cylindrical key plug (202) and a number of locking pins (205a-205g) in a row along a key plug axis for locking the key plug against rotation in the cylindrical bore, and a key (100) of the kind comprising a longitudinally extending, substantially flat key blade (102), with at least two longitudinally extending formations. The key blade comprises an upper edge portion having a first code pattern (103) and a lower, massive portion having a second code pattern (104). At least one of the locking pins in said row is a short pin (205a, 205b, 205c) comprising a first, relatively short key sensing part (207, 208) cooperating with the first code pattern (103), and at least another one of the locking pins in said row is a long pin (205f, 205g, 205h) comprising a second, relatively long key sensing part (210, 207, 208) cooperating with the second code pattern (104).
