The present invention relates to a security locking system of the type comprising a cylinder (3) provided with a set of pistons (8) that are able to be positioned by elastic means on the impression formed in the edge (7b, 7c) of a control key (7) perpendicularly to the direction in which said key (7) is introduced into the cylinder (3), these pistons (8) being able to take up two positions, namely a position retracted into the cylinder (3) when the key (7) is introduced into the latter and an extended position when the key (7) is withdrawn there from. This system is characterized in that:—the cylinder is made up of a locking block (3) of parallelepipedal shape that is able to be received in a receiving block (5),—it comprises locking means which are activated when the locking block (3) is introduced into the receiving block (5).

A lock including a set of tumblers preserving their position after contact with a key to permit blocking of the keyhole during the opening process.

The invention relates to locking devices of enhanced security. primarily locks for locking dead bolt systems of safes, metal doors of residential buildings, public and other buildings and offices, as well as to padlocks, etc., where a high level of resistance to breaking is required.

A lock including a set of tumblers preserving their position after contact with a key to permit blocking of the keyhole during the opening process.

A lock mechanism is disclosed. The lock mechanism includes a body and a clasp with a hole in. The clasp engages and locks with the body. There is also a key receiver with a keyway and a latch biased in a first direction by a spring. The latch has a protrusion for engaging the aperture to lock the clasp to the body. There are split pins which straddle a shear line between the latch and key receiver when in a locked condition and that do not straddle the shear line when the correct key is in the keyway. The split pins are biased by springs in a second direction, transverse to said first direction. The lock mechanism also has a retainer for maintaining the engagement of the latch and the key receiver.

A two piece lockout key assembly having a key inserting portion and a mating recess configured within a receiving housing body. The two piece key assembly further provides, in a first variant, a press retractable bearing and seat arrangement configured within a cylindrical shaped receiving body for providing quick single handed bypass/switch engagement by the user irrespective of the rotational position of the insert portion of the key relative to the fixed outer receiving portion. In a second variant, a pair of clasps are pivotally mounted to the body for engaging a lockout cell frame location.

A lock body for a pin lock is of multipart construction and has a main body and a divider, mounted on the main body, with a plurality of bores for receiving springs and locking pins. The mechanical division of the lock body into the main body and the divider allows simpler and more cost-effective production since the lock body no longer needs to be complicatedly machined out of a solid material, for example brass, but rather more cost-effective production methods can be used.

A multiple bearing locking mechanism module comprising driver bearings, track bearings, slidable boltlock blocks comprised of springs (or magnetic equivalent) and a crossbolt therein. One or more modules are controlled by a master boltlock bolt/vault either by axial or vertical movement depending on embodiment, thus compressing one or more driver bearings into the track bearings. The track bearings expand into the slidable boltlock blocks housing the crossboltslidably disposed in the bearing trackcompressing the crossbolt into the bossbolt locking port, manifesting the locked state. The multiple bearing locking mechanism module can be encompassed in but not limited to, gate locks, safes, briefcases, toolboxes, toy boxes, multiple shackle padlocks, door locks, cable locks, et cetera.
