Abstract

A worksurface assembly includes a support structure and a top portion that is movable relative to the support structure. The worksurface assembly may include a mounting rail configured to support various accessory units. A utility supply system is provided, and the top portion of the worksurface assembly may be moved to provide access to the utility supply system. A mechanism provides for controlled movement of the top portion of the worksurface assembly relative to the support structure.

Claims

1. A worksurface assembly comprising:

a support structure;

a horizontally extending utility trough;

a worksurface member movably connected to the support structure for horizontal frontward and rearward movement between a forward extended position and a rearward retracted position relative to the support structure, and wherein the worksurface member substantially prevents access to the utility trough when in the retracted position, and permits access to the utility trough when the worksurface member is in the extended position, the worksurface member defining an enlarged upwardly-facing upper surface, a front edge, and a rear edge that is opposite the front edge;

an elongated accessory rail connected to the support structure, the accessory rail extending along the rear edge of the worksurface member when the worksurface member is in the rearward retracted position, wherein the accessory rail is configured to releasably support accessory units positioned generally adjacent the rear edge of the worksurface member.

2. The worksurface assembly of claim 1, wherein:

the utility trough comprises an upwardly opening trough structure that is generally U-shaped in cross section.

3. The worksurface assembly of claim 2, wherein:

the accessory rail defines an upper side, a forward side and a rearward side, and wherein at least a portion of the forward side is spaced apart from the rear edge of the worksurface member when the worksurface member is in the rearward retracted position to form a gap between the accessory rail and the worksurface member whereby utility lines can be routed from the utility trough through the gap to a location above the worksurface member.

4. The worksurface assembly of claim 3, wherein:

the forward side of the accessory rail and the rear edge of the worksurface member are linear such that the gap comprises an elongated slot having a generally uniform transverse dimension.

5. The worksurface assembly of claim 4, wherein:

the accessory rail includes an upwardly opening elongated slot configured to receive connectors of accessory units therein.

6. The worksurface assembly of claim 5, wherein:

the accessory rail comprises spaced apart upwardly facing horizontal surfaces extending along forward and rearward sides of the elongated slot, the accessory rail further comprising a vertical rear surface; and

including;

at least one accessory unit having a connecting structure engaging the support rail, the connecting structure comprising a first downwardly extending first portion received in the elongated slot, and a second downwardly extending portion abutting the vertical rear surface of the accessory rail, the connecting structure further including a downwardly facing surface abutting at least one of the upwardly facing horizontal surfaces.

7. The worksurface assembly of claim 6, wherein:

the accessory unit comprises a document support unit.

8. The worksurface assembly of claim 1, including:

a movement control device permitting movement of the worksurface member in the rearward direction, and selectively restricting movement of the worksurface member in the frontward direction to retain the worksurface member in the rearward retracted position;

wherein;

the movement control device includes a first engagement member attached to one of the support structure and the worksurface member, and a second engagement member attached to the other of the support structure and the worksurface member such that the first engagement member moves relative to the second engagement member upon movement of the worksurface member relative to the support structure, and wherein;

the first engagement member is biased into engagement with the second engagement member and permits movement of the worksurface member in the first direction and substantially prevents movement of the worksurface member in the second direction.

9. The worksurface assembly of claim 8, including:

a movable release member operably connected to the first engagement member such that movement of the release member disengages the first engagement member from the second engagement member and permits movement of the worksurface member in the frontward direction.

10. The worksurface assembly of claim 9, wherein:

the first and second guide structures include tapered guide surfaces forming an enlarged entrance to the gap such that contact between the second engagement member and the tapered guide surfaces causes the second engagement member and the worksurface member to shift in a direction that is transverse to the first direction as the worksurface member is moved to the retracted position.
