Abstract

The present invention relates to chairs and work stations. One embodiment of the present invention is for a chair comprising a base and a seat supported by the base, wherein the seat has a seat front and a seat back. The chair includes a backrest and a backrest support for supporting the backrest in a position relative to the seat which allows the seat to be utilized in a first and a second mode of operation. The first mode of operation includes an occupant sitting on the seat facing forward, and the second mode of operation includes an occupant sitting on the seat facing rearward. A stowable table is attached to the backrest. When in an upright position the stowable table extends in a substantially rearward direction. The stowable table may be stowed when not in use. A method of setting up and utilizing a portable work station is also described. The method includes utilizing a chair-table combination wherein the table is stowable. Particular embodiments of the invention are optimized for use as a manicurist'"'"'s chair-table, and a portable laptop support.

Claims

1. A chair comprising:

a base;

a seat supported by the base and having a seat front and a seat back, wherein the seat front and the seat back define a forward direction as referenced from the seat back toward the seat front and a rearward direction as referenced from the seat front toward the seat back;

a backrest;

backrest support means for supporting the backrest in a position relative to the seat which allows the seat to be utilized in a first mode of operation and a second mode of operation, wherein the first mode of operation includes an occupant sitting on the seat facing forward, and wherein the second mode of operation includes an occupant sitting on the seat facing rearward, the backrest support means being supported by the base and connected to the backrest;

a stowable table; and

table support means including a pivotal axis, for supporting the stowable table in a stowed position and in an upright position, wherein in the upright position the stowable table extends rearward from a position near the backrest in a generally horizontal orientation, and in the stowed position the stowable table extends downward from the pivotal axis in a substantially vertical orientation, the table support means being connected to the backrest and the stowable table.

2. The chair of claim 1, wherein the backrest support means comprises a central support post connected to the backrest and the base, wherein the backrest, the central support post, and the seat define a left leg opening and a right leg opening, whereby an occupant may utilize the seat in the second mode of operation by positioning a left leg in the left leg opening and a right leg in the right leg opening.

3. The chair of claim 2, wherein the backrest is vertically adjustable relative to the seat.

4. The chair of claim 1, wherein the table support means comprises a hinge connecting the stowable table to the backrest, whereby the stowable table may be swung between the stowed position to the upright position.

5. The chair of claim 4, wherein the hinge is a horizontal hinge connected to the backrest.

6. The chair of claim 5, wherein the stowable table extends in a substantially vertical downward orientation from the horizontal hinge connected to the backrest when the stowable table is in the stowed position.

7. The chair of claim 1, wherein the stowable table extends horizontally from the backrest when the stowable table is in the upright position.

8. The chair of claim 7, wherein the stowable table extends perpendicularly from the backrest when the stowable table is in the upright position.

9. The chair of claim 1, wherein the stowable table comprises a top surface, the top surface including a wrist pad.

10. The chair of claim 1, wherein the backrest comprises a top portion, the top portion including a wrist pad.

11. The chair of claim 10, wherein the stowable table extends from a location below the backrest top portion wrist pad.

12. The chair of claim 11, wherein the location from which the table extends is spaced an optimal distance below the wrist pad for utilizing a keyboard lying on the stowable table top surface.

13. A mobile work station comprising:

a base;

a seat having a front and a back and defining corresponding forward and backward directions, respectively;

a vertical support member having an upper portion, a lower portion, and a horizontal support member attached to the upper portion, wherein the vertical support member is attached to the base near the seat back to position the horizontal support member at a lower back support height and to define a first leg opening between the horizontal support member and the seat, the first leg opening being sufficiently large to accommodate a leg of a user seated on the seat facing backward and the lower back support height corresponding to a height at which the horizontal support member is positioned to provide lower back support for a user seated on the seat facing forward; and

a work surface having a first edge, a second edge and a top surface, the first edge being attached to the horizontal support member and the work surface extending from the horizontal support member.

14. The apparatus of claim 13, wherein the work surface first edge is hingedly attached to the horizontal support member, and the work surface is movable between a first up position corresponding a generally horizontal orientation and a down position corresponding to a substantially downwardly vertical position.

15. The apparatus of claim 14, wherein the work surface is adjustable among a plurality of up orientations, including the first up position.

16. The apparatus of claim 14, wherein the horizontal support member comprises a lip extending above the first edge of the work surface when the work surface is in one of the up positions.

17. The apparatus of claim 16, wherein:

the lip extends over the first edge of the work surface; and

the horizontal support member comprises padding over the lip.

18. The apparatus of claim 17, wherein the work surface comprises a pad located on the top surface near the second edge.

19. The apparatus of claim 13, wherein:

the seat back comprises a center portion;

the vertical support member is attached to the base near the center portion of the seat back;

the vertical support member, the horizontal support member, and the seat define a second leg opening wherein the first leg opening is on a first side of the vertical support member and the second leg opening is on a second side of the vertical support member; and

the work surface first edge is hingedly attached to the horizontal support member, wherein the work surface is movable between a first up position corresponding to a generally horizontal position and a down position corresponding to a substantially downwardly vertical position.

20. The apparatus of claim 19, wherein the horizontal support member comprises a padded lip extending over the first edge of the work surface when work surface is in the first up position.

21. The apparatus of claim 19, wherein the work surface comprises an elongated pad at the second edge.

22. The apparatus of claim 19, wherein the base comprises:

a vertically adjustable center post having a first end attached to the seat, and a second end opposite the first end; and

a plurality of legs extending from the second end, each of the legs including a caster.

23. The apparatus of claim 19, wherein the horizontal support member is vertically adjustable relative to the seat.
