Abstract

Container retention and release apparatus are disclosed. An example container retention and release apparatus includes a swaybrace to engage an exterior surface of a container. A latch is to attach to an internal receptacle of the container to retain the container. The latch is movable between a latched position to retain the container and an unlatched position to release the container. A drive is to move the latch between the latched position and the unlatched position.

First claim

What is claimed is:

1. A container retention and release apparatus comprising:
a first ejector assembly having a first swaybrace and a second ejector assembly having a second swaybrace, the first ejector assembly being spaced apart from the second ejector assembly, the first swaybrace to engage a first portion of an exterior surface of a container and the second swaybrace to engage a second portion of the exterior surface of the container different than the first portion; and
a retention apparatus to retain the container positioned between the first ejector assembly and the second ejector assembly, the retention apparatus including:
a latch to attach to an internal receptacle of the container to retain the container, the latch movable between a latched position to retain the container and an unlatched position to release the container; and
a drive to move the latch between the latched position and the unlatched position.

2. The apparatus of claim 1 , wherein the latch includes a lock carried by a post.

3. The apparatus of claim 2 , wherein the drive includes a piston slidably coupled relative to the post, the piston to move to a first position to engage the lock and cause the lock to engage a shoulder formed in the internal receptacle of the container when the latch is in the latched position, the piston to move to a second position to allow the lock to disengage or release the shoulder when the latch is in the unlatched position.

4. The apparatus of claim 2 , further including a collar carried by the post, the collar to retain the lock coupled to the post when the latch is in the unlatched position and the post is removed from the internal receptacle.

5. The apparatus of claim 1 , wherein the latch includes a hook to engage the internal receptacle when the latch is in the latched position, the hook to release the receptacle when the latch is in the unlatched position.

6. The apparatus of claim 5 , wherein the drive is to cause the hook to pivot between a first position when the latch is in the latched position and a second position when the latch is in the unlatched position.

7. The apparatus of claim 1 , wherein the latch includes a first latch and a second latch, and the internal receptacle includes a first internal receptacle and a second internal receptacle, the first latch to interface with the first internal receptacle and the second latch to interface with the second internal receptacle.

8. The apparatus of claim 7 , wherein the first latch includes a first hook and the second latch includes a second hook spaced from the first hook.

9. A container retention and release apparatus comprising:
a swaybrace to engage an exterior surface of a container;
a post to be at least partially received by an internal receptacle of the container;
a lock carried by the post, the lock being movable between a latched position to retain the container and an unlatched position to release the container;
a piston slidably coupled relative to the post, the piston to move the lock between the latched position and the unlatched position;
a collar slidably coupled to an outer surface of the post between a first collar position to retain the lock and a second collar position to release the lock; and
a collar biasing element to bias the collar to the first collar position to retain the lock coupled to the post when the latch is in the unlatched position and the post is removed from the internal receptacle, the collar to move to the second collar position via engagement with the container when the post is at least partially received by the internal receptacle of the container to release the latch when the latch is in the latched position.

10. The apparatus of claim 9 , wherein the lock is to engage a shoulder formed in the internal receptacle when the lock is in the latched position.

11. The apparatus of claim 10 , wherein the piston is to move between a first stroke position to allow the lock to move to the unlatched position and a second stroke position to move the lock to the latched position.

12. The apparatus of claim 11 , wherein the piston includes a first portion having a first diameter and a second portion adjacent the first portion having a second diameter different than the first diameter.

13. The apparatus of claim 12 , wherein the second portion is to cause the lock to engage the shoulder of the receptacle when the piston is in the second stroke position and the first portion is to allow the lock to release the shoulder of the internal receptacle when the piston is in the first stroke position.

14. A method including:
retaining a container to a container retention and release apparatus by engaging an exterior surface of a container via a swaybrace and engaging a shoulder of an internal receptacle of the container via a lock spaced from the swaybrace;
biasing the lock toward a latched position via a piston slidably coupled to a post supporting the lock when the lock is positioned in the receptacle;
releasing the container by moving the lock from the latched position at which the lock engages the shoulder of the internal receptacle of the container to an unlatched position at which the lock disengages from the shoulder of the internal receptacle; and
retaining the lock within the post via a collar slidably coupled to the post via a collar biasing element, the collar to retain the lock within the post in response to the lock being removed from the internal receptacle.

15. The method of claim 14 , wherein releasing the container includes operating a first drive to move the lock between the latched position and the unlatched position and operating a second drive different than the first drive to release the container from the swaybrace.

16. The method of claim 14 , wherein the retaining of the container by engaging the shoulder of the internal receptacle includes at least partially inserting the piston in the internal receptacle to a first position to cause an enlarged diameter portion of the piston to bias the lock into engagement with the shoulder of the internal receptacle.

17. The method of claim 16 , wherein the moving of the lock from the latched position to the unlatched position includes moving the piston from the first position to a second position to cause a reduced diameter portion of the piston to allow the lock to disengage the shoulder of the internal receptacle.

18. A container retention and release apparatus comprising:
a first ejector assembly having a first swaybrace and a second ejector assembly having a second swaybrace, the first ejector assembly being spaced apart from the second ejector assembly, the first swaybrace to engage a first portion of an exterior surface of a container and the second swaybrace to engage a second portion of the exterior surface of the container different than the first portion;
a first latch to be at least partially received by a first internal receptacle of the container, the first latch being pivotally coupled to a first housing of the first ejector assembly; and
a second latch to be at least partially received by a second internal receptacle of the container, the second latch being pivotally coupled to a second housing of the second ejector assembly.

19. The apparatus of claim 18 , wherein the first latch includes a first hook and the second latch includes a second hook.

20. The apparatus of claim 19 , wherein the first hook engages a first shoulder of the first receptacle when the first hook is in a first latched position and the second hook engages a second shoulder of
