A storage assembly adapted to be secured to a work surface includes an enclosure defining an interior, wherein the enclosure is adapted to be secured around an opening in the work surface. A platform is disposed within the enclosure, and a cover is connected to the enclosure and configured to enclose the interior of the enclosure. The cover is movable between a closed position and an open position, wherein the cover in the closed position forms a top wall for the enclosure, and wherein the cover in the open position exposes the platform. A movement control arrangement is connected between the enclosure, the platform and the cover. The movement control arrangement and the enclosure have cooperating guide slot structure for receiving and guiding the platform, and enabling raising and lowering of the platform within the enclosure in response to movement of the cover between the open and closed positions.

1. A storage assembly adapted to be secured to a work surface, the storage assembly comprising: an enclosure defining an interior, wherein the enclosure is adapted to be secured below an opening in the work surface;a platform disposed within the enclosure;a cover connected to the enclosure by a set of hinge brackets, and configured to enclose the interior of the enclosure, the cover being movable between a closed position and an open position, wherein the cover in the closed position forms a top wall for the enclosure, and wherein the cover in the open position exposes the platform;a movement control arrangement connected between the enclosure, the platform and the cover, wherein the movement control arrangement and the enclosure have cooperating guide slot structure for receiving and guiding the platform, and enabling raising and lowering of the platform within the enclosure in response to movement of the cover between the open and closed positions,wherein the movement control arrangement includes a set of shuttle plates mounted for longitudinal movement simultaneously in a same direction relative to the enclosure during movement of the cover between the open and closed positions;wherein the shuttle plates include vertical guide slots which receive engagement pins that are provided on the hinge brackets and are guided up and down in the vertical guide slots as the cover moves between the open and closed positions; andwherein the hinge brackets are provided with opening spring mechanisms engaged with the work surface when the cover is in the closed position, and disengaged from the work surface when the cover is in the open position. 2. The storage assembly of claim 1, wherein the movement control arrangement is slidably confined within the enclosure for movement between the enclosure and the platform. 3. The storage assembly of claim 1, wherein the shuttle plates include substantially angled guide slots aligned with vertical guide slots formed on the enclosure. 4. The storage assembly of claim 3, wherein the platform has guide pins received for movement in the aligned angled guide slots and vertical guide slots. 5. The storage assembly of claim 1, further comprising a locking mechanism disposed on the enclosure and releasably engaged with the cover for releasably retaining the cover in the closed position. 6. The storage assembly of claim 1, wherein the shuttle plates further include gear racks disposed between the vertical guide slots and the angled guide slots formed on the shuttle plates. 7. The storage assembly of claim 6, wherein the enclosure is provided with at least one damper gear engageable with one of the gear racks on the shuttle plates to control movement of the platform and the cover. 8. A work surface comprising: a work support member having an upper surface, a lower surface and an opening extending from the upper surface to the lower surface;a storage assembly secured around the opening, the storage assembly including an enclosure having a bottom wall and upwardly extending side and front walls that cooperate to define an interior and are secured to the work support member, a platform disposed within the enclosure and a cover pivotally secured to the enclosure by a pair of hinge brackets, and movable between a closed position and an open position, wherein the cover is substantially coplanar with the upper surface of the work support member in the closed position; anda movable shuttle arrangement connected between the enclosure, the platform and the cover, wherein opening of the cover moves the shuttle arrangement within the enclosure in one direction along a first path formed in the shuttle arrangement, and causes the platform to be raised in the enclosure along a second path defined by aligned guide slots in the shuttle arrangement and the enclosure, and closing of the cover moves the shuttle arrangement within the enclosure along the first path in another direction opposite to the one direction, and causes the platform to be lowered within the enclosure along the second path,wherein the shuttle arrangement includes a pair of shuttle plates mounted for longitudinal movement simultaneously in a same direction relative to both the enclosure and platform during movement of the cover between the open and closed positions,wherein the shuttle plates each include a pair of upwardly and rearwardly extending guide slots, a vertical guide slot and a horizontal slot formed with a gear rack,wherein the vertical guide slots receive engagement pins that are provided on the hinge brackets, and are guided up and down in the vertical guide slots as the cover moves between the open and closed positions, andwherein the hinge brackets are provided with opening spring mechanisms engaged with the work surface when the cover is in the closed position, and disengaged from the work surface when the cover is in the open position. 9. The work surface of claim 8, wherein at least one shuttle plate is slidably connected relative to the enclosure by means of a damper gear engaged in the gear rack. 10. The work surface of claim 8, wherein the side walls of the enclosure are formed with vertical guide slots that are aligned with the upwardly and rearwardly extending guide slots of the shuttle plates. 11. The work surface of claim 10, wherein the platform has guide pins that are engaged for travel in the aligned guide slots on the enclosure and shuttle plates. 12. The work surface of claim 8, wherein the shuttle plates are mounted for sliding movement in planes parallel to planes of the side walls of the enclosure. 13. A method for selectively storing and exposing an object relative to a work surface, the method comprising the steps of: (a) providing a work support surface having an opening, a storage assembly including an enclosure defining an interior and secured around the opening, a platform disposed within the interior of the enclosure, a cover pivotally secured to the enclosure by a pair of hinge brackets, the cover being movable between an open position and a closed position, and a movement control arrangement connected between the enclosure, the platform and the cover, wherein the movement control arrangement and the enclosure are formed with cooperating guide slot structure for receiving and guiding the platform and wherein the object is disposed on the platform;(b) selectively pivoting the cover away from the enclosure and towards the open position to actuate the movement control arrangement such that the platform is raised along a path defined by the cooperating guide slot structure to expose the object on the platform; and(c) selectively pivoting the cover towards the enclosure and the closed position to actuate the movement control arrangement such that the platform is lowered along the path defined by the cooperating slot structure to store the object on the platform within the enclosure,wherein the movement control arrangement includes a pair of shuttle plates having vertical guide slots which receive engagement pins that are provided on the hinge brackets, and are guided up and down in the vertical guide slots as the cover moves between the open and closed positions, andwherein the hinge brackets are provided with opening spring mechanisms engaged with the work surface when the cover is in the closed position, and disengaged from the work surface when the cover is in the open position.
