Abstract

A latch includes a housing that has a first side and a second side. The latch includes a bolt locking assembly that is positioned at least partially within the housing. The bolt locking assembly includes a bolt movable between first and second positions relative to at least one of the first and second sides of the housing. The bolt is positionable to selectively extend from either the first side or the second of the housing. The latch includes a first handing configuration and a second handing configuration, where the first handing configuration corresponds to the first position and the second handing configuration corresponds to the second position. Changing between the first handing configuration and the second handing configuration requires moving the bolt locking assembly to a disengaged position and applying the external force to the bolt to move the bolt between the first and second positions.

First claim

I claim:

1. A latch comprising:
a housing having a first side and a second side;
a bolt assembly positioned at least partially within the housing, the bolt assembly including a bolt movable longitudinally within the housing between a first position and a second position;
a bolt locking assembly, wherein the bolt locking assembly has an engaged position and a disengaged position, wherein when in the engaged position, the bolt locking assembly interfaces with the bolt to prevent movement of the bolt between the first and second positions and, when in the disengaged position, the bolt locking assembly allows movement of the bolt, and wherein the bolt locking assembly is linearly movable relative to the housing between the engaged and disengaged positions and biased toward the engaged position by at least one bolt locking assembly spring;
a bolt spring in contact with the bolt, wherein the bolt spring biases the bolt toward at least one of the first position and the second position;
a bolt movement assembly, including:
a locking cylinder mechanism movable between a locked position and an unlocked position, the locking cylinder mechanism being connected to the bolt locking assembly, the locking cylinder mechanism being accessible from the first side of the housing;
a control connected to the bolt locking assembly, the control being accessible from the second side of the housing, wherein, when actuated, the control moves the bolt locking assembly between the engaged and disengaged positions;
a cam connected to the locking cylinder mechanism, the cam interfacing with an inner surface of the bolt locking assembly and configured to rotate with the locking cylinder mechanism, wherein when the cam engages with the inner surface of the bolt locking assembly, the cam moves the bolt locking assembly to the disengaged position by moving the bolt locking assembly against the bias of the at least one bolt locking assembly spring, and

wherein, when the bolt locking assembly is disengaged from the bolt, the bolt is moved within the housing initially only by an external force between the first position and the second position, and wherein the movement of the bolt is partially assisted by the bolt spring toward one of the first or second positions of the bolt.

2. The latch of claim 1 , further comprising a first handing configuration and a second handing configuration, wherein the first handing configuration corresponds to the first position of the bolt and the second handing configuration corresponds to the second position of the bolt.

3. The latch of claim 2 , wherein changing between the first handing configuration and the second handing configuration requires moving the bolt locking assembly to the disengaged position and applying the external force to the bolt to move the bolt between the first and second positions.

4. The latch of claim 1 , wherein the external force is force exerted by a hand of a user.

5. The latch of claim 1 , further comprising a receiving mechanism mountable adjacent the housing, wherein the receiving mechanism is configured to receive the bolt.

6. The latch of claim 1 , wherein the control is accessible from the first side of the housing.

7. The latch of claim 1 , wherein the latch is mounted to a hinged barrier.

8. The latch of claim 7 , wherein the hinged barrier is a gate.

9. The latch of claim 1 , wherein the bolt includes a notch which interfaces with the bolt locking assembly.

10. The latch of claim 1 , wherein the bolt locking assembly includes first and second lock portions that are configured to interface with the bolt.

11. The latch of claim 10 , wherein the first and second lock portions extend upwardly and are configured to interface with a notch in the bolt.

12. The latch of claim 1 , wherein the cam is symmetrical.

13. The latch of claim 1 , wherein the movement of the bolt is partially assisted by the bolt spring at a midpoint between the first and second positions toward the first or second position that the bolt is moving toward.

14. A method of operating a latch comprising:
providing a latch including:
a bolt movable between a first position and a second position relative to a housing;
a locking cylinder mechanism movable between a locked position and an unlocked position, the locking cylinder mechanism being connected to the bolt, the locking cylinder mechanism having a keyhole;
a first handing configuration and a second handing configuration, wherein the first handing configuration corresponds to the first position of the bolt and the second handing configuration corresponds to the second position of the bolt;

mounting the latch to an interior side of a gate;
positioning the locking cylinder mechanism so that the keyhole is accessible from an exterior side of the gate;
mounting a receiving mechanism to a surface adjacent the latch, wherein the receiving mechanism is aligned with the bolt so that the receiving mechanism is configured to receive and retain the bolt when the locking cylinder mechanism is in the locked position; and
choosing the first or second handing configuration of the bolt by applying an external force to the bolt to move the bolt longitudinally within the housing between the first and second positions so that the locked position of the locking cylinder mechanism positions the bolt within the receiving mechanism.

15. The method of claim 14 , wherein the latch further includes a bolt locking assembly, wherein the bolt locking assembly has an engaged position and a disengaged position, wherein when in the engaged position, the bolt locking assembly interfaces with the bolt to prevent movement of the bolt between the first and second positions and, when in the disengaged position, the bolt locking assembly allows movement of the bolt, and wherein the bolt locking assembly is linearly movable relative to the housing between the engaged and disengaged positions and biased toward the engaged position by at least one bolt locking assembly spring.

16. The method of claim 15 , wherein changing between the first handing configuration and the second handing configuration requires moving the bolt locking assembly to the disengaged position and applying the external force to the bolt to move the bolt between the first and second positions.

17. The method of claim 15 , wherein the bolt locking assembly includes first and second lock portions that are configured to interface with the bolt.

18. The method of claim 17 , wherein the first and second lock portions extend upwardly and are configured to interface with a notch in the bolt.

19. The method of claim 14 , wherein when choosing the first or second handing configuration of the bolt, the bolt is maintained in the latch.

20. A latch comprising:
a housing having a first side and a second side;
a bolt assembly positioned at least partially within the housing, the bolt assembly including a bolt movable through the housing between a first position and a second position;
a bolt locking assembly, wherein the bolt locking assembly has an engaged position and a disengaged position, wherein when in the engaged position, the bolt locking assembly interfaces with the bolt to prevent movement of the bolt between the first and second positions and, when in the disengaged position, the bolt locking assembly allows movement of the bolt, and wherein the bolt locking assembly is linearly movable relative to the housing between the engaged and disengaged positions and biased toward the engaged position by at least one bolt locking assembl
