Abstract

A lock for an access point such as a window includes a dual-action locking mechanism with a locking unit and a blocker. The locking unit is movable between a locking position and an unlocking position. The blocker blocks movement of the locking unit when the blocker is in a blocking position, and permits movement of the locking unit when the blocker is in an unblocking position. The lock may capture an insert attached to a tether to permit partial opening of a window while the unit is locked.

First claim

What is claimed is:

1. A window lock comprising:
a rotatable locking unit constructed and arranged to rotate between a locking position and an unlocking position;
a blocker having a blocking surface which is configured to prevent rotation of the locking unit from the locking position to the unlocking position when the blocker is in a blocking position; and
a key that is axially insertable into the locking unit, wherein:
the key is constructed and arranged to travel within the locking unit in an axial direction of the key and apply a force to the blocker in the axial direction to push the blocker out of the blocking position; and
with the blocker out of the blocking position, the blocker is positioned outside of the locking unit, and the blocking surface is not positioned to prevent rotation of the locking unit from the locking position to the unlocking position; and
the key and the locking unit are adapted such that rotation of the key rotates the locking unit.

2. The window lock of claim 1 , further comprising a housing, wherein the locking unit and blocker are positioned in the housing.

3. The window lock of claim 2 , further comprising a tether, wherein the locking unit is adapted to secure the tether to the housing when the locking unit is in the locking position and release the tether from the housing when the locking unit is in the unlocking position.

4. The window lock of claim 3 , wherein the tether comprises an insert adapted to be attached to the housing, and the rotatable locking unit is arranged to prevent release of the insert from the housing when the rotatable locking unit is in the locking position, and the rotatable locking unit is arranged to permit release of the insert from the housing when the locking unit is in the unlocking position.

5. The window lock of claim 1 , wherein the key comprises at least three faces arranged on an outer circumference of the key, and the at least three faces are arranged to contact the locking unit to rotate the locking unit between the locking position and the unlocking position.

6. The window lock of claim 1 , wherein the blocker is positioned on a bending member, and the key is constructed and arranged to bend the bending member via axial movement of the key within the locking unit.

7. The window lock of claim 1 , wherein the key includes an insertion end, and the insertion end passes all the way through and extends out of the locking unit.

8. The window lock of claim 1 , wherein the key includes a retaining channel adapted to retain the key in the locking unit when the locking unit is in the unlocking position.

9. The window lock of claim 1 , wherein the blocking surface is configured to prevent rotation of the locking unit from the unlocking position to the locking position when the blocker is in the blocking position.

10. The window lock of claim 1 , wherein the locking unit includes a key stop adapted to stop the travel of the key in the axial direction when the blocker is out of the blocking position.

11. A lock comprising:
a locking unit constructed and arranged to rotate between a locking position and an unlocking position;
a blocker positioned on a bending member, the blocker having a blocking surface which is configured to prevent rotation of the locking unit from the locking position to the unlocking position when the blocker is in a blocking position, and wherein the bending member is cantilevered; and
a key constructed and arranged to be inserted into the locking unit, wherein:
the key is constructed and arranged to push at least one of the blocker and bending member to bend the bending member and move the blocker out of the blocking position.

12. The lock of claim 11 , wherein the lock is a window lock.

13. The window lock of claim 12 , wherein the locking unit is constructed and arranged to rotate between the locking position and the unlocking position.

14. The window lock of claim 12 , further comprising a housing, wherein the locking unit and blocker are positioned in the housing.

15. The window lock of claim 14 , further comprising a tether, wherein the locking unit is adapted to secure the tether to the housing when the locking unit is in the locking position and release the tether from the housing when the locking unit is in the unlocking position.

16. The window lock of claim 15 , wherein the tether comprises an insert adapted to be attached to the housing, and the locking unit is arranged to prevent release of the insert from the housing when the locking unit is in the locking position, and the locking unit is arranged to permit release of the insert from the housing when the locking unit is in the unlocking position.

17. The window lock of claim 12 , wherein the key comprises at least three faces arranged on an outer circumference of the key, and the at least three faces contact the locking unit to move the locking unit between the locking position and the unlocking position.

18. The window lock of claim 12 , wherein the key is constructed and arranged to bend the bending member via axial movement of the key within the locking unit.

19. The window lock of claim 12 , wherein the key includes an insertion end, and the insertion end passes all the way through and extends out of the locking unit.

20. The window lock of claim 12 , wherein the key is constructed and arranged to push the blocker to bend the bending member and move the blocker out of the blocking position.

21. The window lock of claim 12 , wherein the key includes a retaining channel adapted to retain the key in the locking unit when the locking unit is in the unlocking position.

22. The window lock of claim 12 , wherein the blocking surface is configured to prevent rotation of the locking unit from the unlocking position to the locking position when the blocker is in the blocking position.

23. The window lock of claim 12 , wherein the locking unit includes a key stop adapted to stop the travel of the key in an axial direction of the key when the blocker is out of the blocking position.

24. A window lock comprising:
a rotatable locking unit constructed and arranged to rotate between a locking position and an unlocking position;
a blocker having a blocking surface which is configured to prevent rotation of the locking unit from the locking position to the unlocking position when the blocker is in a blocking position; and
a key including a retaining channel that is insertable into the locking unit, the key including an insertion end, wherein:
the insertion end is constructed and arranged to apply a force to the blocker to move the blocker out of the blocking position, and the insertion end is constructed and arranged to pass all the way through and extend out of the locking unit; and
with the blocker out of the blocking position the blocker is positioned outside of the locking unit, and the blocking surface is not positioned to prevent rotation of the locking unit from the locking position to the unlocking position; and
the key and the locking unit are adapted such that rotation of the key rotates the locking unit; and
the retaining channel retains the key in the locking unit when the locking unit is in the unlocking position.

25. The window lock of claim 24 , further comprising a housing, wherein the locking unit and the blocker are positioned in the housing.

26. The window lock of claim 25 , further comprising a tether, wherein the locking unit is adap
