Cylinder Lock with Interact Mobile Devices
A tumbler pin lock includes one or two auxiliary locking mechanisms including an auxiliary locking pin, and an auxiliary blocking component to provide enhance locking in addition to the locking provided by the tumbler pins so that the lock remains locked even if the tumblers are picked or bumped into their unlocked positions. A cylinder lock is provided with an auxiliary locking pin which projects into the keyway, which, with the proper key, is slid forward with a mobile device into an area in the lock housing where an auxiliary groove allows the cylinder plug to turn. The second locking component, which is approximately rectangular similarly has a post that is moved forward with the insertion of the proper key into an annular groove allowing the cylinder plug to turn.
1 . A lock comprising:
a cylindrical plug having an axially-extending key way adapted to receive a conforming key;
a mobile device that slides axially that hold a plurality of tumbler pins disposed within radially-oriented tumbler pin holes formed in said mobile and adapted to control rotation of said cylindrical plug, wherein said tumbler pins are constructed and arranged to be engaged by the conforming key inserted into said keyway and to be positioned by the key within their respective tumbler pin holes to create a shear line between the plug and a lock housing shell;
the mobile device having a projection on top;
the lock housing shell having locking pins located that project into all but one annular grooves in which the projection of the mobile device turns;
Whereby the mobile device in disposed within said cylindrical plug recesses and moveable in an axial direction between a first position and a second position, said mobile being constructed and arranged to be engaged by the conforming key inserted into the keyway to move said mobile device from the first position into the second position, wherein said second position of the mobile device aligns the tumbler pins to create a shear and aligns the projection of the mobile device into a annular groove without blocking pins, allowing the plug to turn.
2 . The lock according to claim 1 , wherein said mobile device is disposed within a recess formed in said cylindrical plug adjacent said keyway and includes a contact surface projecting into said keyway so as to be engaged by a key inserted into said keyway.
3 . The lock according to claim 1 , where two or more mobile devices are utilized, and where the key has a number of blades that are equal to recesses in the cylindrical plug.
4 . The lock of claim 1 with multiple sets of locking pins at different location within each annular groove.
5 . The lock according to claim 1 , further comprising elastic elements that acts in a longitudinal plane to biasing the mobile devices toward the internal surface of the keyway.
6 . A lock system comprising the lock according to claim 1 and a key configured to be inserted into said keyway to position said tumbler pins to engage said mobile device to move from its first position to its second position so as to permit said cylindrical plug to rotate.
7 . A lock system comprising the lock according to claim 1 and a key configured to be inserted into said keyway to position said tumbler pins to create a shear line and to move the projection on the mobile device into a groove without blocking pins to permit said cylindrical plug to rotate and unlock.
8 . A lock comprising:
a cylindrical plug having an axially-extending keyway adapted to receive a conforming key;
a second mobile device that slides axially that hold a plurality of tumbler pins disposed within radially-oriented tumbler pin holes formed in said mobile device and adapted to block rotation of said cylindrical plug, wherein said tumbler pins are constructed and arranged to be engaged by the conforming key inserted into said keyway and to be positioned by the key within their respective tumbler pin holes to create a shear line between the plug and a lock housing shell;
the second mobile device having a projection on top;
the second mobile device having a second blocking component with a post that sits further back from the keyway;
whereby inserting the key in the keyway and proceeding, the area of the key gets engaged with the rear surface of the second mobile element and start to move it in the direction of the rear part of the cylinder to the second position where the second mobile elements post aligns with a groove in the inner shell housing, concurrently the teeth in the blade line up the tumbler pins until they create a shear line, and, the second mobile device moves into a predefined position where the post of the projection on the second mobile device is placed in a right annular groove without blocking pins, at which time the plug is in an unlocked position and free to rotate to open the cylinder.
9 . The lock according to claim 8 , wherein said mobile device is disposed within a recess formed in said cylindrical plug adjacent said keyway and includes a contact surface projecting into said keyway so as to be engaged by a key inserted into said keyway.
10 . The lock according to claim 8 , where two or more mobile devices are utilized, and where the key has a number blades that are equal to the recesses in the cylindrical plug.
11 . The lock of claim 8 with multiple sets of locking pins at different locations within each annular groove.
12 . The lock according to claim 8 , further comprising elastic elements that acts in a longitudinal plane to biasing the mobile devices toward the internal surface of the lock housing shell.
13 . A lock system comprising the lock according to claim 8 and a key configured to be inserted into said keyway to position said tumbler pins so as to permit said cylindrical plug to rotate and to engage said mobile device to move said mobile device from its first position to its second position.
12 . The lock system of claim 8 , wherein said mobile device is disposed within a recess formed in said cylindrical plug adjacent said keyway and includes a contact surface projecting into said keyway and said key includes a key blade and a contact surface formed on said key blade for engaging the second mobile device.
