Abstract

A transportable component stand having interactive upper and lower frame members wherein components can be raised and lowered by an electromechanical crank including an electric motor and threaded shaft, which raises and lowers the upper frame member on the lower frame member. Closable front and rear covers are also included. The stand allows a user to transport, store and use the components in a variety of environments.

Claims

1. A transportable stand comprising two interactive frame members, an upper frame member and a lower frame member, wherein the upper frame member has mounted thereon components for user interaction, said upper frame member being adapted to be selectively raised and lowered on the lower frame member by means for varying component height comprising an electric motor which cooperates with a threaded shaft, and means for enabling movement of the stand comprising wheels attached to the lower frame member, said stand further comprising a three position front cover for enclosing at least one of the components pivotable between a closed position, an open stowed position and an open display position.

2. The transportable stand of claim 1 further comprising a lock associated with the front cover for limiting access to the components thereunder.

3. The transportable stand of claim 1 further comprising a back cover to limit access to the back of at least one of the components.

4. The transportable stand of claim 3 wherein the back cover includes a power supply cord and power switch.

5. The transportable stand of claim 3 wherein the back cover includes means to store a keyboard.

6. The transportable stand of claim 3 wherein the back cover is lockable to prohibit unauthorized access.

7. The transportable component stand of claim 1 further comprising means to releasably attach a keyboard onto the upper frame member which can be moved from a stored position to a use position.

8. The transportable stand of claim 1 further comprising handle means associated with the upper frame member to increase maneuverability of the stand.

9. The transportable stand of claim 1 further comprising curtain support structure means on which a privacy curtain can be hung to provide privacy to the user of the components.

10. The transportable stand of claim 1 wherein the mean height of the components can be varied from about 36" to about 60".

11. The transportabide stand of claim 1 further comprising a closeable storage compartment associated with the upper frame member.

12. The transportable stand of claim 1 further comprising a closeable storage compartment associated with the lower frame member.

13. The transportable stand of claim 12 further comprising a battery back-up for the components on the stand within the closable storage compartment.

14. The transportable stand of claim 1 wherein the means for varying component height further comprises a gear reduction box associated with the electric motor and threaded shaft and a nut actuator which engages the threaded shaft.

15. The transportable stand of claim 14 wherein the electric motor, gear reduction box and threaded shaft engage the upper frame member and the nut actuator engages the lower frame member, wherein when the upper frame member is raised the shaft is rotated against the actuator to push the upper frame member upwardly against the actuator on the-lower frame member.

16. The transportable stand of claim 1 wherein the upper frame member comprises male vertical side members which are insertable into female vertical side members of the lower frame member, and ride therein, to provide support and guidance for the upper frame member.

17. The transportable stand of claim 16 further comprising slide bearings associated with said male and female vertical side members to facilitate sliding interaction.
