What is claimed is:
1. A tray for supporting a plurality of input devices on substantially the same plane comprising a base including a top surface, a bottom surface and a peripheral surface therebetween, said peripheral surface being defined by a front surface, a rear surface and opposite side surfaces, a groove opening upwardly through said top surface and through said opposite side surfaces, said groove being defined by a bottom surface and two opposite inwardly opposing front and rear surfaces, a slidable member including a top surface, a bottom surface and a peripheral surface, said slidable member peripheral surface including a front surface, a rear surface and opposite side surfaces, said slidable member being in slidable engagement with said groove for right-to-left and left-to-right movement in a substantially horizontal plane, said slidable member top surface and said base top surface lying substantially in a common plane, and stop means for limiting the sliding movement of said slidable member in each of the right-to-left and left-to-right movements thereof.
2. The tray as defined in claim 1 wherein at least one of said base and said slidable portion are substantially arc-shaped in profile.
3. The tray as defined in claim 1 wherein said base and said slidable member are each substantially arc-shaped in profile.
4. The tray as defined in claim 1 wherein said slidable member is slidable between a left-most extended position and a right-most extended position thereby permitting the placement of a plurality of input devices on the top surface of the slidable member.
5. The tray as defined in claim 1 wherein said slidable member is slidable between a left-most extended position and a right-most extended position thereby permitting the placement of a plurality of input devices on the top surface of the slidable member, and adjacent ones of said base and slidable member opposite side surfaces are in contiguous transitional relationship to each other alternatively in each of maximum left-hand and right-hand positions of said slidable member relative to said base.
6. The tray as defined in claim 1 wherein one of said plurality of input devices is a computer keyboard and another of said plurality of input devices is one of a mouse, track ball, a joy stick, and an electronic writing pad.
7. The tray as defined in claim 1 wherein said slidable member opposite side surfaces are curved to smoothly align with said base opposite side surfaces when the slidable member is moved completely to either the right or the left.
8. The tray as defined in claim 1 wherein the base is of a one-piece, integral substantially homogenous construction.
9. The tray as defined in claim 1 wherein the base includes a first base member defining said groove bottom surface and two spaced top members defining said groove front and rear surfaces.
10. The tray as defined in claim 1 wherein the base includes a first base member defining said groove bottom surface and two spaced top members defining said groove front and rear surfaces, and a separate mounting plate carried by said base bottom surface.
11. The tray as defined in claim 9 wherein said two spaced top members are attached one proximate said base front surface and one proximate said base rear surface.
12. The tray as defined in claim 10 wherein said separate mounting plate is attached to said base bottom surface substantially centered relative to said base opposite side surfaces.
13. The tray as defined in claim 7 wherein said stop means is a stop proximate each of said slidable member slide surfaces, and said stops each include a curved surface substantially corresponding in shape to the associated slide member side surface.
14. The tray as defined in claim 13 wherein an inside surface of each stop contacts an associated one of said base opposite side surfaces to limit maximum right or left sliding movement of said slidable member.
15. The tray as defined in claim 13 wherein each of said stops is substantially aligned with an associated one of said slidable member opposite end surfaces.
16. The tray as defined in claim 1 wherein said base bottom surfaces pre-drilled for attachment to a support.
17. The tray as defined in claim 16 wherein said support is an articulating mechanism adapted to be attached to one of a desk and a table.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A lifting lug apparatus comprising:
a mounting plate adapted for attachment to an upper portion of an object to be lifted;
a lifting lug defining a hook aperture, the lifting lug pivotally attached to the mounting plate such that the hook aperture is movable from a lateral position, wherein the hook aperture is oriented in a lateral plane extending outward from the mounting plate and outward from an attached object to be lifted to an upright position, wherein the hook aperture is oriented in an upright plane extending upward from the mounting plate;
wherein the lifting lug is biased toward the lateral position.
2. The apparatus of claim 1 wherein the lifting lug is biased toward the lateral position by a counterweight attached to the lifting lug.
3. The apparatus of claim 2 wherein the counterweight comprises a plate extending laterally from the lifting lug and configured such that the plate bears against one of the mounting plate and the object to lifted when the lifting lug is in the lateral position.
4. The apparatus of claim 1 wherein the lifting lug is pivotally attached to the mounting plate about a substantially horizontal pivot axis.
5. The apparatus of claim 1 wherein the mounting plate is adapted for attachment to the object to be lifted such that when the lifting lug is in the upright position, the hook aperture is above a top edge of the object to he lifted.
6. A tank apparatus comprising:
a tank comprising a substantially upright wall and a top attached to a top edge of the wall;
a lifting lug defining a hook aperture the lifting lug pivotally attached to an upper portion of the wall such that the hook aperture is movable from a lateral position, wherein the hook aperture is oriented in a lateral plane extending outward from the wall, to an upright position, wherein the hook aperture is oriented in an upright plane extending upward above the top edge of the wall;
wherein the lifting lug is biased toward the lateral position.
7. The apparatus of claim 6 wherein the lifting lug is biased toward the lateral position by a counterweight attached to the lifting lug.
8. The apparatus of claim 7 wherein the counterweight comprises a plate extending laterally from the lifting lug and configured such that the plate bears against the wall when the lifting lug is in the lateral position.
9. The apparatus of claim 6 wherein the lifting lug is pivotally attached to the upper portion of the wall about a substantially horizontal pivot axis.
10. The apparatus of claim 9 wherein the lifting lug is pivotally attached to a mounting plate about the substantially horizontal pivot axis, and the mounting plate is attached to the upper portion of the wall.
