Rail and shelf assemblies and rack formed therewith, and methods of installing rail and shelf assemblies on a rack
View Patent ↗Rail assemblies on either side of a shelf each include a rail reciprocated to a slide adjustable from a rail-locking position to a post-locking position. The slide is configured to restrain the rail from reciprocating longitudinally relative to the slide, when the slide occupies a rail-locking position and the rail occupies a stowage position relative to the slide. The slide is configured to enable the rail to reciprocate longitudinally relative to the slide and to releasably secure a rack post, when the slide occupies the post-locking position.
1. A rail assembly, comprising:
a rail mounted to a fixture for movement between a lowered position and a raised position, the fixture including a detent structure and adjustable between an open position and a closed position; and
the fixture movable from the open position to the closed position when the detent structure is engaged to a complemental detent structure of a rack post for entrapping the rack post disabling the detent structure from disengaging from the complemental detent structure.
2. The rail assembly according to claim 1 , further comprising a drive member operatively coupled between the rail and the fixture, whereby adjustment of the drive member imparts corresponding movement of the rail between the lowered position and the raised position.
3. The rail assembly according to claim 1 , wherein the rail is configured to reciprocate relative to the fixture in response to movement of the rail between the lowered position and the raised position.
4. The rail assembly according to claim 1 , further comprising a handle carried by the fixture.
5. A shelf assembly, comprising:
rail assemblies on either side of a shelf for supporting objects, each said rail assembly comprising a rail mounted to a fixture for movement between a lowered position and a raised position, the fixture including a detent structure and adjustable between an open position and a closed position; and
the fixture movable from the open position to the closed position when the detent structure is engaged to a complemental detent structure of a rack post for entrapping the rack post disabling the detent structure from disengaging from the complemental detent structure.
6. The rail assembly according to claim 5 , further comprising a drive member operatively coupled between the rail and the fixture, whereby adjustment of the drive member imparts corresponding movement of the rail between the lowered position and the raised position.
7. The rail assembly according to claim 5 , wherein the rail is configured to reciprocate relative to the fixture in response to movement of the rail between the lowered position and the raised position.
8. The rail assembly according to claim 5 , further comprising a handle carried by the fixture.
9. A method, comprising:
mounting a rail to a fixture for movement between a lowered position and a raised position, the fixture including a detent structure and adjustable between an open position and a closed position;
operatively coupling a drive member between the rail and the fixture, whereby adjustment of the drive member imparts corresponding movement of the rail between the lowered position and the raised position;
engaging the detent structure to a complemental detent structure of a rack post while the fixture is in the open position; and
adjusting the fixture from the open position to the closed position entrapping the rack post disabling the detent structure from disengaging from the complemental detent structure.
10. The method according to claim 9 , further comprising adjusting the drive member.
11. A method, comprising:
providing rail assemblies on either side of a shelf for supporting objects, each said rail assembly comprising a rail mounted to a fixture for movement between a lowered position and a raised position, the fixture including a detent structure and adjustable between an open position and a closed position;
operatively coupling a drive member between the rail and the fixture of each said rail assembly, whereby adjustment of the drive member imparts corresponding movement of the rail of each said rail assembly between the lowered position and the raised position;
engaging the detent structures to complemental detent structures of first and second rack posts, respectively, while each said fixture is in the open position; and
adjusting each said fixture from the open position to the closed position entrapping the first and second rack posts, respectively, disabling the detent structures from disengaging from the complemental detent structures of the first and second rack posts, respectively.
12. The method according to claim 11 , further comprising adjusting the drive member.
