Claims
- 1. A lock bolt in a rotary closure cylinder (24) of a safety lock, said rotary closure cylinder (24) having a housing spring acting on a back end of an associated housing pin, said lock bolt having a bolt tip (2) and a bolt head (3) both of which are slidably located in a rotor of the safety lock, said bolt head (3) having a back wall engaged against the associated housing pin for sliding the associated housing pin into the rotary closure cylinder (24) when the rotor of the safety lock is rotated by a corresponding key,
- wherein the bolt tip (2) is supported in the bolt head (3) so that it is slidable longitudinally in a limited fashion between an inner position and an outer position;
- wherein spring biasing means are engaged between the bolt tip (2) and the back wall (4) of the bolt head (3) for forcing the bolt tip (2) away from the bolt head (3);
- said spring biasing means exerting a force between the bolt tip (2) and the bolt head (3) substantially less than a force exerted by the housing spring on the back end of the associated housing pin; and
- whereby a vibrational movement exerted on the bolt tip (2) is absorbed by said spring biasing means and is not transmitted to the bolt head (3) so that said associated housing pin is not slid into said rotary closure cylinder (24) to permit unauthorized opening of the safety lock.
- 2. The lock bolt according to claim 1, wherein the bolt head (3) has a longitudinal bore (5) in which the bolt tip (2) is supported so that it can slide.
- 3. The lock bolt according to claim 2, wherein the longitudinal bore (5) is a blind bore.
- 4. The lock bolt according to claim 2, wherein the longitudinal bore (5) has a lateral recess (6) in which a projection (7) of the bolt tip (2) is engaged in detent fashion.
- 5. The lock bolt according to claim 3, wherein the longitudinal bore (5) has a lateral recess (6) in which a projection (7) of the bolt tip (2) is engaged in detent fashion.
- 6. The lock bolt according to claim 2, wherein said spring biasing means includes a first spring element (8) supported in the bolt head (3) and secures the bolt tip (2) in a position of repose in the outer position.
- 7. The lock bolt according to claim 3, wherein said spring biasing means includes a first spring element (8) supported in the bolt head (3) and secures the bolt tip (2) in a position of repose in the outer position.
- 8. The lock bolt according to claim 4, wherein said spring biasing means includes a first spring element (8) supported in the bolt head (3) and secures the bolt tip (2) in a position of repose in the outer position.
- 9. The lock bolt according to claim 6, wherein the bolt tip (2) can be slid from the outer position into the inner position counter to the force of the spring element (8).
- 10. The lock bolt according to claim 1, wherein a locking pin (9) is supported in the bolt head (3), protrudes out the back wall (4) of the bolt head (3), and can be lowered counter to a second spring element (10) into the bolt head (3).
- 11. The lock bolt according to claim 2, wherein a locking pin (9) is supported in the bolt head (3), protrudes out the back wall (4) of the bolt head (3), and can be lowered counter to a second spring element (10) into the bolt head (3).
- 12. The lock bolt according to claim 4, wherein a locking pin (9) is supported in the bolt head (3), protrudes out the back wall (4) of the bolt head (3), and can be lowered counter to a second spring element (10) into the bolt head (3).
- 13. The lock bolt according to claim 6, wherein a locking pin (9) is supported in the bolt head (3), protrudes out the back wall (4) of the bolt head (3), and can be lowered counter to a second spring element (10) into the bolt head (3).
- 14. The lock bolt according to claim 9, wherein a locking pin (9) is supported in the bolt head (3), protrudes out the back wall (4) of the bolt head (3), and can be lowered counter to a second spring element (10) into the bolt head (3).
- 15. The lock bolt according to claim 10, wherein the second spring element (10) acting on the pin (9) is disposed in a longitudinal bore (12) of the bolt tip (2).
- 16. The lock bolt according to claim 8, wherein a longitudinal bore (12) of the bolt tip (2) opens into a peg-shaped projection (16) of the bolt tip (2).
- 17. The lock bolt according to claim 1, wherein the rotary closure cylinder (24) has at least one lock bolt.
- 18. The lock bolt according to claim 1, wherein the bolt tip (2) includes a peg-shaped projection (16) on a back side thereof, whereby the peg-shaped projection is slidable longutidinally.
- 19. A lock bolt in a rotary closure cylinder of a safety lock, comprising
- a bolt tip (2) and
- a bolt head (3);
- said bolt tip (2) and bolt head (3) being slidably located in a rotor of said safety lock;
- the bolt head (3) being placed against a housing pin for sliding the associated housing pin into the rotary closure cylinder (24) when the rotor of the safety lock is rotated by a corresponding key;
- a compression spring (8) in a blind bore of the bolt head (3) engaged between the bolt tip (2) and the bolt head (3); and
- the bolt tip (2) being supported in the bolt head (3) so that it is slidable longitudinally in a limited fashion between an inner and an outer position,
- whereby a vibrational movement exerted on the bolt tip (2) is absorbed by the compression spring (8) and is not transmitted back to the bolt head (3) to slide said associated housing pin into said rotary closure cylinder (24).
