Abstract

A support system for use with a door that closes off an opening and a door assembly with the support system. The support system comprises a first support assembly having a main body and a roller assembly connected thereto, the main body comprises a seat for establishing connection with a first position of said door and a connector formed with the seat for connecting with the roller assembly. The connector is displaced from the seat in at least one perspective such that the roller assembly connected thereto is staggered relative to the seat in that perspective.

First claim

The invention claimed is:

1. A support system for use with a door that closes off an opening, the support system comprising:
a first support assembly comprising a main body;
a roller assembly connected to the main body;
a track defining two pathways that guide movement of respective rollers situated therein;
the main body comprises a seat for establishing connection with a first position of said door and a connector formed with the seat for connecting with the roller assembly;
wherein the connector is displaced from the seat in at least one perspective such that the roller assembly connected thereto is staggered relative to the seat in that perspective, and
wherein the connector is pivotally connected to a shaft to which the roller is rotatably affixed, such that the seat is pivotable relative to the roller about a pivotal axis that is displaced from the seat in the at least one perspective.

2. The support system as claimed in claim 1 , further comprising a second support assembly comprising a second main body identical in construction to the main body of the first support assembly such that the second main body is interchangeable with the main body.

3. The support system as claimed in claim 2 , wherein the second support assembly includes a roller assembly connected to the main body through the connector that is displaced from the main body in at least one perspective such that the roller assembly connected thereto is staggered relative to the seat in that perspective.

4. The support system as claimed in claim 3 , wherein the connector of the second support assembly is pivotally connected to a shaft to which the roller is rotatably affixed, such that the seat is pivotable relative to the roller about a pivotal axis displaced from the seat in the at least one perspective.

5. The support system as claimed in claim 4 , wherein the roller is rotatable about a rotational axis which extends traversely to the pivotal axis.

6. The support system as claimed in claim 4 , wherein the seat of the first support assembly is pivotable relative to the roller about a pivotal axis which is aligned with that of the second support assembly when these assemblies are assembled to said door thereby functioning as a pair that pivots about a same pivotal axis.

7. The support system as claimed in claimed in claim 3 , wherein the second support assembly further includes a track defining a pathway that guide movement of the roller of the second support assembly, which is situated therein.

8. The support system as claimed in claim 2 , wherein the main body of the second support assembly comprises a seat that has two portions defining an arcuate angle therebetween for establishing connection with respective surfaces on said door.

9. The support system as claimed in claim 1 , wherein the roller assembly includes two rollers rotatable about transversely arranged rotational axis.

10. The support system as claimed in claim 1 , wherein the seat includes two portions defining an arcuate angle therebetween for establishing connection with respective surfaces on said door.

11. The support system as claimed in claim 10 , wherein the arcuate angle is a right angle.

12. A door assembly comprising two or more door panels interconnected by a hinge joint thereby permitting pivotal movement between door panels, wherein at least one of the door panels is provided with the support system as claimed in claim 1 such that the at least one of the door panels includes roller for sliding along a predetermined pathway.

13. The door assembly as claimed in claim 12 , wherein the hinge joint is pivotal about a first pivotal axis and the support system includes a second pivotal axis about which the door panel pivots relative to the roller.

14. The door assembly as claimed in claim 13 , wherein the first and second pivotal axis are provided on a same imaginary plane.
