Abstract

Examples described herein relate to a latch for releasably coupling objects. In some such examples, the latch includes a receiver, a torque member, and a handle. The receiver includes a lobe to releasably engage an anchor point within a recess of the receiver. The torque member is rotatably coupled to the receiver to rotate the receiver. The handle includes a torque portion rotatably coupled to the torque member to rotate the torque member and includes a lever extending from the torque portion.

First claim

What is claimed is:

1. A latch transitionable between an open configuration and a latched configuration, the latch comprising:
a receiver including a first set of gear features, a first lobe, a second lobe, and a first recess defined by the first lobe and the second lobe,
wherein the receiver interacts with an anchor point which is part of an object to be secured by being inserted into the latch and which moves between a first position and a second position,
wherein the first lobe engages the anchor point disposed within the first recess and holds the anchor point in the first position as the latch transitions into the latched configuration,
wherein the second lobe releases the anchor point from the first recess as the latch transitions from the latched configuration to the open configuration such that the anchor point moves and returns to the second position when the anchor point is removed from the first recess, and
wherein the receiver includes a second recess;

a lockout member comprising a pin and a release lobe,
wherein the pin is positioned to engage the second recess of the receiver when the latch is in the open configuration, and

wherein the release lobe is positioned to interface with the anchor point and allow the anchor point to push and rotate the lockout member, such that the pin is disengaged from the second recess of the receiver when the anchor point moves into the first recess as the latch transitions from the open configuration to the latched configuration;
a torque member rotatably coupled to the receiver and comprising a second set of gear features complementary to and interacting with the first set of gear features as the torque member rotates the receiver; and
a handle, including:
a torque portion rotatably coupled to the torque member and comprising a third set of gear features complementary to and interacting with the second set of gear features as the torque portion rotates the torque member and the receiver, and
a lever extending from the torque portion for rotating the torque portion.

2. The latch of claim 1 , wherein an application of force on the lever in a first direction engages the anchor point within the first recess and an application of force on the lever in a second direction opposite the first direction disengages the anchor point from the first recess as the latch transitions from the latched configuration to the open configuration.

3. The latch of claim 1 , wherein the receiver, the torque member, and the handle convey a mechanical advantage such that a first force applied to the anchor point by the first lobe of the receiver is greater than a second force applied to the handle.

4. The latch of claim 1 , wherein the lockout member is coupled to a shaft and allowed to rotate around the shaft.

5. The latch of claim 1 , wherein the release lobe includes a portion beyond the receiver and radially outward, thereby allowing the lockout member to be disengaged manually.

6. The latch of claim 1 , further comprising a spring coupled to the lockout member, the spring to position the pin in the second recess of the receiver when the latch is in the open configuration.

7. The latch of claim 1 , wherein:
the receiver is a first receiver; and
the latch further comprises:
a second receiver defining a third recess rotatably coupled to the torque member, the second receiver including a third lobe releasably engaging the anchor point within the third recess of the second receiver,
the first receiver and the second receiver are disposed along a common shaft, and
the first receiver and the second receiver are disposed on opposite sides of the lockout member.

8. The latch of claim 1 , further comprising a torsion spring coupled to the torque member and applying a bias force on the torque member to bias the latch towards the open configuration when not in the latched configuration.

9. A latch device transitionable between an open configuration and a latched configuration, comprising:
a receiver disposed along a first shaft and including a first lobe and a second lobe opposite the first lobe, the first lobe and the second lobe defining a first recess, the receiver interacting with an anchor point which is part of an object to be secured by being inserted into the latch device and which moves between a first position and a second position, the first lobe releasably engaging the anchor point within the first recess of the receiver to hold the anchor point in the first position when the latch is in the latched configuration and the second lobe releasing the anchor point such that the anchor point moves and returns to the second position, thereby disengaging the anchor point from the first recess as the latch transitions from the latched configuration to the open configuration;
wherein, in the open configuration, the first lobe and the second lobe are oriented in a same direction relative to a main body of the receiver, and
wherein the receiver includes a second recess;

a torque member disposed along a second shaft and rotatably coupled to the receiver;
a handle disposed along a third shaft and rotatably coupled to the torque member; and
a lockout member disposed along a fourth shaft and having a pin to engage the receiver when the latch device is in the open configuration,
wherein the pin is positioned to engage the second recess of the receiver when the latch is in the open configuration, and
wherein the lockout member further comprises a release lobe positioned to interface with the anchor point and allow the anchor point to push and rotate the lockout member, such that the pin is disengaged from the second recess of the receiver when the anchor point moves into the first recess as the latch transitions from the open configuration to the latched configuration.

10. The latch device of claim 9 , wherein the receiver, the torque member, and the handle convey a mechanical advantage such that a rotational force applied to the anchor point by the receiver is greater than a rotational force applied to the handle.

11. The latch device of claim 9 , wherein the release lobe includes a portion radially outward from the receiver, thereby allowing the lockout member to be disengaged manually.

12. The latch device of claim 9 , wherein:
the torque member is rotatably coupled to the receiver by a first set of complimentary gear features; and
a torque portion of the handle is rotatably coupled to the torque member by a second set of complimentary gear features.

13. A method for operating a latch transitionable between an open configuration and a latched configuration, the method comprising:
rotating a handle of the latch in a first direction to transition the latch into the open configuration and in a second direction to transition the latch into the latched configuration;
rotating a torque member of the latch by the rotation of the handle; and
rotating a receiver by the rotation of the torque member, the receiver including a first lobe, a second lobe, and a first recess defined by the first lobe and the second lobe, the rotation of the receiver including:
the first lobe engaging an anchor point that transitions between a first position and a second position, the first lobe holding the anchor point in the first position within the first recess as the latch rotates into the latched configuration, wherein the anchor point is part of an object to be secured by being inserted into the latch;
the second lobe releasing the anchor point from the first recess and into the second position as the latch transitions into the open configuration;
wherein the rotation of the receiver moves the first lobe and the second lobe such that
