Abstract

A table assembly includes a worksurface and at least one leg assembly coupled to the worksurface and configured to support the worksurface above a floor surface, the at least one leg assembly including a first leg member having an aperture located along a length of the first leg member, the aperture having a first diameter, a second leg member telescoping received within the first leg member and having a threaded bore located along a length of the second leg member, the bore having a second diameter that is larger than the first diameter, and an engagement member having a first portion threadably received within the bore of the second leg member and a second portion configured to be selectively received within the aperture of the first leg member thereby telescopingly fixing the second leg member with respect to the first leg member.

Claims (35)

1. A table assembly, comprising:

a worksurface; and

at least one leg assembly coupled to the worksurface and configured to support the worksurface above a floor surface, the at least one leg assembly comprising:

a first leg member having a plurality of apertures located along a length of the first leg member, each of the apertures of the plurality of apertures having a first diameter;

a second leg member telescoping received within the first leg member and having a threaded bore located along a length of the second leg member, the bore having a second diameter that is larger than the first diameter; and

a set screw having a first portion threadably received within the bore of the second leg member and a second portion including a tool-receiving aperture, where the set screw is configured to move between a first position where the first portion is located within the bore of the second leg member and the second portion is received within one of the apertures of the plurality of apertures of the first leg member, thereby fixing the second leg member with respect to the first leg member, and a second position where the first portion is located within the bore of the second leg member and the second portion is withdrawn from the aperture of the plurality of apertures of the first leg member, thereby allowing the second leg member to be longitudinally adjusted with respect to the first leg member.

2. The table assembly of claim 1 , wherein the tool-receiving aperture is configured to receive an Allen wrench.

3. The table assembly of claim 1 , wherein the first leg member has a first end coupled to the worksurface and a second end that telescoping receives the second leg member.

4. The table assembly of claim 1 , wherein the set screw includes a tapered end portion.

5. The table assembly of claim 1 , wherein the at least one leg assembly includes a plurality of leg assemblies.

6. The table assembly of claim 1 , wherein the set screw is configured to abut an inner wall of the first leg member when the set screw is in the first position.

7. A table assembly, comprising:

a worksurface; and

at least one leg assembly coupled to the worksurface and configured to support the worksurface above a floor surface, the at least one leg assembly comprising:

a first leg member having an aperture located along a length of the first leg member, the aperture having a first diameter;

a second leg member telescoping received within the first leg member and having a threaded bore located along a length of the second leg member, the bore having a second diameter that is larger than the first diameter; and

an engagement member having a first portion threadably received within the bore of the second leg member and a second portion configured to be received within the aperture of the first leg member thereby telescopingly fixing the second leg member with respect to the first leg member.

8. The table assembly of claim 7 , wherein the engagement member comprises a set screw.

9. The table assembly of claim 7 , wherein the second portion of the engagement member includes a tool-receiving aperture.

10. The table assembly of claim 9 , wherein the tool-receiving aperture is configured to receive an Allen wrench.

11. The table assembly of claim 7 , wherein the engagement member is configured to move between a first position where the first portion is located within the bore and the second portion is received within the aperture and a second position where the first portion is located within the bore and the second portion is withdrawn from the aperture.

12. The table assembly of claim 11 , wherein the engagement member is configured to abut an inner wall of the first leg member when the engagement member is in the first position.

13. The table assembly of claim 7 , wherein the first leg member has a first end coupled to the worksurface and a second end that telescoping receives the second leg member.

14. The table assembly of claim 7 , wherein the aperture is one of a plurality of apertures longitudinally spaced along the length of the first leg member.

15. The table assembly of claim 7 , wherein the engagement member includes a tapered end portion.

16. A method for adjusting a height of a table assembly, comprising:

providing a worksurface;

providing at least one leg assembly coupled to the worksurface and configured to support the worksurface above a floor surface, the at least one leg assembly including a first leg member having a first aperture and a spaced-apart second aperture each located along a length of the first leg member and each having an aperture having a first width, a second leg member telescoping received within the first leg member, the second leg member having a recess having a second width, and an engagement member having a first portion configured to positively engage the recess of the second leg member and a second portion configured to be received within the aperture of the first leg member;

applying a first force to the engagement member to move the engagement member from a first position where the first portion positively engages the recess and the second portion is received within the first aperture, to a second position where the first portion positively engages the recess and the second portion is withdrawn from the first aperture, the engagement member remaining in the second position when the first force is removed from the engagement member and the recess is aligned with the first aperture;

telescopingly adjusting the second leg member with respect to the first leg member; and

applying a second force to the engagement member to move the engagement member from the second position to a third position where the first portion positively engages the recess and the second portion is received within the second aperture, thereby telescopingly locking the first leg member with respect to the second leg member.

17. The method of claim 16 , wherein the first force and the second force are each rotational forces.

18. The method of claim 16 , where the first width is greater than the second width.

19. The method of claim 18 , wherein the recess is a threaded bore.

20. The method of claim 19 , wherein the engagement member includes a set screw having a tool-receiving relief.
