Abstract

A lock that is particularly suitable for locking cabinets, showcases and drawers includes a bolt and a housing having an opening to receive the bolt and having arranged therein a locking member for locking the bolt. The bolt comprises an bolt body, a chamfered head end and a recess part on the elongated bolt body behind the chamfered head end. The locking member is rotatably provided inside the housing and arranged to rotate between a first orientation to lock the bolt and a second orientation different from the first orientation to release the lock. The locking member comprises a bended first end that fits behind the recess part of the bolt when the locking member is rotated to the first orientation. A coil can be used to, when provided with a current, generate a magnetic force to tilt the locking member to the second orientation.

Claims

1. A lock (100) comprising a bolt (1) and a housing (2) having an opening (21) to receive the bolt (1) and having arranged therein a locking member (22) for locking the bolt (1), wherein

the bolt comprises an elongated bolt body (11), a chamfered head end (12) and a recess part (13) in the elongated bolt body (11) behind the chamfered head end (12),

the locking member (22) is rotatably provided inside the housing (2) and arranged to rotate between a first orientation for locking the bolt (1) in the housing (2) and a second orientation different from the first orientation for releasing the bolt (1) from the housing (2), and

the locking member (22) comprises a bended first end (23) that fits in the recess part (13) of the bolt (1) when the bolt (1) is inserted into the opening (21) of the housing (2) and the locking member (22) is rotated to the first orientation.

2. The lock (100) according to claim 1, wherein the housing (2) further comprises a spring (24) applying a spring force to the locking member (22) to force the locking member (22) to the first orientation.

3. The lock (100) according to claim 1 or claim 2, wherein the housing (2) further comprises a coil (25) that, when being provided with a current, generates a magnetic force to a second end (26) of the locking member (22) different from the first end (23) wherein the magnetic force exceeds the spring force resulting in the locking member (22) to be rotated to the second orientation and the bolt (1) to be removable from the housing (2).

4. The lock (100) according to any one of the claims 1-3, wherein the locking member (22) is further bended at an inflection point (27) enabling the rotation of the locking member (22).

5. The lock (100) according to any one of the claims 1-4 wherein the housing (2) comprises a pivot (40) enabling the rotation of the locking member (22).

6. The lock (100) according to any one of the preceding claims, wherein the housing (2) further comprises a switch (28), wherein the switch (28) is in a first state when the bolt (1) is inserted in the housing (2) such that the bolt (1) is lockable by the locking member (22), and wherein the switch (28) is in a second state when the bolt (1) is unlocked and at least partially removed from the housing (2).

7. The lock (100) according to any one of the preceding claims, wherein the bolt (1) comprises a base (14) for attaching the bolt (1) to a movable part of a cabinet, a showcase or a drawer, and wherein the housing (2) comprises one or more screw holes (29) for attaching the housing (2) to a fixed part of the cabinet, the showcase or the drawer.

8. The lock (100) according to any one of the preceding claims, wherein the housing (2) is a rectangular three-dimensional housing comprising two opposite sides having an area smaller than the four other sides, and wherein the opening (21) is in the center of one of the two smaller sides.

9. The lock (100) according to claim 2 and claim 8, wherein the housing (2) further comprises a first recess at a first of the four other sides for fitting the locking member (22) and the spring (24), wherein the first of the four other sides is coverable by a first cover to secure the locking member (22) and the spring (24) inside the housing.

10. The lock (100) according to claim 3 and claim 9, wherein the housing (2) further comprises a second recess at a second of the four other sides opposite of the first of the four other sides for fitting the coil (25), wherein the second of the four other sides is coverable by a second cover to secure the coil (25) inside the housing (2).

11. The lock (100) according to claim 6 and claim 10, wherein the housing (2) further comprises a third recess at the second of the four other sides for fitting the switch (28), and wherein the second of the four other sides is coverable by the second cover to further secure the switch (28) inside the housing (2).

12. The lock (100) according to any one of the preceding claims, wherein the housing (2) further comprises an electronic circuit for conditionally providing the current to the coil (25), wherein the electronic circuit comprises a processor programmable to detect a data pattern in a data signal and to enable the current to the coil (25) if the data pattern is detected.

13. A security system comprising:

one or more locks (100) according to any one of the claims 1-12, each lock (100) comprising a coil (25) which, when being provided with a current, generates a magnetic force to a second end (26) of a locking member (22) different from a first end (23) resulting in the locking member (22) to be rotated to a second orientation and a bolt (1) to be removable from a housing (2);

a power supply (3) configured to provide a current to the one or more locks (100) for activating the coil (25);

an unlocking switch (4) coupled between the power supply (3) and the one or more locks (100); and

an unlocking device (5) configured to detect an authorized user causing the unlocking switch (4) to providing the current to the one or more locks (100) from the power supply (3) to thereby unlock the one or more locks (100).

14. The security system according to claim 13, wherein the unlocking device (5) is one of a tag reader for detecting an authorized tag, a fingerprint reader for detecting an authorized fingerprint, or a code reader for detecting an authorized code entered by a user.

15. The security system according to claim 13 or claim 14, wherein the unlocking switch (4) is configured to detect a removal of the bolt (1) from the housing (2) of a first lock and upon detection of the removal cutting the current to the one or more locks other than the first lock.

16. The security system according to any one of the claims 13-15, wherein the unlocking switch (4) is configured to cut the current to the one or more locks (100) after a predefined time period to lock the one or more locks (100) after unlocking.
