Abstract

A workstation table includes at least two horizontally oriented spaced worksurface struts which allow a work platform to be placed atop the worksurface struts to extend between them. Leg struts having adjustable length extend downwardly from the workstation struts, and a crank link extending between the leg struts can be rotated to adjust the length of both of the leg struts simultaneously. Base struts extend from the ends of the leg struts opposite the worksurface struts to better support the base struts. Stabilizer struts, which also preferably have adjustable length, extend between the opposing base struts and/or between the opposing leg struts to help maintain them in spaced relation. The various struts are made of tubing and are affixed together with strut clamps formed of clamp shells, with each clamp shell being shaped to complementarily fit about portions of adjoining struts in such a manner that the clamp shells may be affixed about the adjoining portions to attach them together.

Claims

1. A workstation table comprising:

a. at least two spaced worksurface struts, the worksurface being horizontally oriented to accommodate a work platform atop and between the worksurface struts;

b. at least two spaced leg struts, each leg strut descending from one of the workstation struts, wherein the leg struts each include leg strut segments which slide with respect to each other in parallel relation to adjust the length of the leg strut;

c. at least two base struts, each base strut extending horizontally from one of the leg struts;

d. strut clamps wherein;

(1) each strut clamp joints;

i. one of the worksurface struts to one of the leg struts, or

ii. one of the base struts to one of the leg struts, and

(2) each strut clamp includes at least two clamp shells wherein;

i. each lamp shell is adapted to accommodate a portion of at least one of the struts which it joins, and

ii. the clamp shells of each strut clamp may be affixed together with at least one of the struts to which the strut clamp is joined resting therebetween;

e. a crank link extending between the leg struts, wherein rotation of the crank link causes concurrent length adjustment in the leg struts.

2. The workstation table of claim 1 wherein:

a. within each leg strut, one of the leg strut segments has a drive shaft extending generally perpendicularly to the length of the leg strut and also extending through opposing sides of the leg strut; and

b. the crank link extends between the drive shafts of the leg struts.

3. The workstation table of claim 2 further comprising a crank affixed to the drive shaft of one of the leg struts.

4. The workstation table of claim 2 wherein the leg strut segments within each leg strut are coaxially and telescopically fit together.

5. The workstation table of claim 2 wherein the drive shafts extend through the strut clamps.

6. The workstation table of claim 1 wherein the strut clamp shells are identical.

7. The workstation table of claim 1 further comprising at least one stabilizer strut, each stabilizer strut extending between:

a. a pair of the base struts, or

b. a pair of the leg stats,

wherein each stabilizer strut includes at least a pair of stabilizer strut segments which are slideable with respect to each other in parallel relation to thereby allow adjustment in the length of the stabilizer strut.

8. A workstation table comprising:

a. at least two spaced horizontally oriented worksurface struts whereupon a work platform may be placed;

b. at least two spaced horizontally oriented base struts, each base strut also being spaced from one of the worksurface struts;

c. at least two spaced leg struts, each leg strut extending downwardly from one of the workstations struts to one of the base struts, wherein the leg struts have adjustable length to thereby allow adjustment in the height of the worksurface struts;

d. at least one stabilize strut each stabilizer strut extending between;

i. a pair of the base struts, or

ii. a pair of the leg struts,

wherein each stabilizer strut includes at least a pair of stabilizer strut segments which slide with respect to each other in parallel relation to adjust the length of the stabilizer strut;

e. strut clamps wherein;

(1) each strut clamp joins;

i. one of the base struts to one of the leg struts, or

ii. one of the stabilizer struts to one of the base struts or one of the leg struts;

(2) each strut clamp includes at least two clamp shells wherein;

i. each clamp shell is shaped to receive a portion of at least one of the struts which it join, and

ii. the clamp shells of each strut damp may be affixed together with the struts to which the strut clamp joined resting between the clamp shells.

9. The workstation table of claim 8 wherein each strut clamp has:

a. a sun portion affixed to one of the opposing ends of the stabilizer strut, and

b. a branch portion having an internal passage sized to receive one of the base struts or one of the leg struts therein,

wherein the internal passage has adjustable size.

10. The workstation table of claim 8 wherein the strut clamp shells are identical.

11. The workstation table of claim 8 wherein:

a. the leg struts each include at least a pair of leg strut segments which slide with respect to each other in parallel relation to adjust the length of the leg strut; and

b. a crank link extends between the leg struts and adjusts their lengths simultaneously.

12. The workstation table of claim 11 wherein:

a. each leg strut includes a drive shaft extending through opposing sides of the leg strut,

b. the crank link extends between the drive shafts of the leg struts, and

c. at least one of the leg struts has a crank affixed to its drive shaft.

13. A workstation table comprising:

a. at least two horizontally-extending worksurface struts, the worksurface struts being spaced to accommodate a work platform atop the worksurface struts and extending therebetween;

b. at least two spaced leg struts, each leg strut extending downwardly from one of the workstation struts, wherein the leg struts have adjustable length;

c. a crank link extending between the leg struts, wherein rotation of the crank link causes concurrent length adjustment in the leg struts;

d. at least two base struts, each base strut;

i. being spaced from one of the worksuface struts with one of the leg struts situated between the base strut and the worksurface strut, and

ii. extending horizontally from one of the leg struts;

e. at least one stabilizer strut, each stabilizer strut extending between;

i. a pair of the base struts, or

ii. a pair of the leg struts,

wherein each stabilizer strut has adjustable length;

f. strut clamps joining adjacent struts, the strut clamps each including at let two clamp shells, wherein;

i. each clamp shell is adapted to accommodate a portion of at least one of the struts therein, and

ii. the clamp shells may be affixed together with at least one of the struts resisting therebetween.

14. The workstation table of claim 13 wherein each leg strut includes leg strut segments which slide with respect to each other in parallel relation to adjust the length of the leg strut.

15. The workstation table of claim 13 wherein each stabilize so includes stabilizer strut segments which slide with e to each other in parallel relation to adjust the length of the stabilizer strut.
