Abstract

The present invention discloses a collapsible cart with a base panel and basket support frame. Two hinge mounts extend from the base frame and a hinge pin extends from each hinge mount. The basket support frame has two support beams that are slidably and rotatable mounted on the hinge pins. Each hinge mount forms a receiving space that can receive and block rotation of each support beam. A cable made of flexible material mounts between the two support beams. When a downward or upward force is exerted on the cable, each end of the cable pulls the support beams towards each other along the longitudinal axis of the hinge pin causing the support beams to move into a position which is clear of the receiving space and allows rotation around the hinge pins towards the base panel and into a collapsed position.

Claims (46)

1. A collapsible cart comprising:

a base panel having an outer perimeter frame and a base surface;

first and second hinge mounts extending from base panel;

first and second hinge pins wherein said first hinge pin is connected to said first hinge mount and said second hinge pin is connected to said second hinge mount;

and wherein said hinge mounts are U-shaped members comprising of a first wall, a second wall, and a third wall;

a basket support frame comprising first and second support beams;

wherein said first support beam is slidably and rotatably mounted to said first hinge pin and said second support beam is slidably and rotatably mounted to said second hinge pin;

wherein said basket support frame can rotate between a collapsed position and an upright position;

wherein said first and second support beams are lockable in an upright position;

at least one basket mountable on said first and second support beams; and

wherein said basket is comprised of at least one support member.

2. The collapsible cart of claim 1 further comprising at least three wheels attached to said base panel.

3. A collapsible cart comprising:

a base panel having an outer perimeter frame and a base surface;

first and second hinge mounts extending from base panel;

and wherein said hinge mounts are U-shaped members comprising of a first wall, a second wall, and a third wall;

first and second hinge pins wherein said first hinge pin is connected to said first hinge mount and said second hinge pin is connected to said second hinge mount;

a basket support frame comprising first and second support beams;

wherein said first support beam is slidably and rotatably mounted to said first hinge pin and said second support beam is slidably and rotatably mounted to said second hinge pin;

wherein said basket support frame can rotate between a collapsed position and an upright position;

wherein said first and second support beams are slidable along the longitudinal axis of said first and second hinge pins between a first position and second position;

wherein when said first and second support beams are in the first position said first and second support beams are locked in an upright position and when said first and second support beams are in said second position said first and second support beams are capable of rotating around said first and second hinge pins;

a flexible cable connected between said first and second support beams, wherein applying tension to said cable displaces each of said first and second support beams from said first position into said second position;

at least one basket member mountable on said first and second support beams; and

wherein said basket member is comprised of at least one support member.

4. The collapsible cart of claim 3 wherein said first and second hinge mounts can block rotation of said first and second support beams around said first and second hinge pins when said first and second support beams are in said first position.

5. The collapsible cart of claim 3 wherein said basket member can prevent movement of said first and second support beams along the longitudinal axis of said first and second hinge pins when said first and second support beams are in said first position and said at least one basket member is mounted on said first and second support beams.

6. The collapsible cart of claim 3 wherein said base panel can block rotation of said first and second support beams in one direction.

7. The collapsible cart of claim 3 wherein when said basket support frame is rotated to a collapsed positioned said first and second support beams are positioned above and generally parallel to said base surface.

8. The collapsible cart of claim 7 further comprising at least one latch wherein said latch is capable of locking said basket support fame in said collapsed position.

9. The collapsible cart of claim 3 wherein said basket support frame further comprises a handle.

10. The collapsible cart of claim 3 further comprising a basket handle connected to said at least one basket member.

11. The collapsible cart of claim 3 further comprising a plurality of mounting hooks attached to said first and second support beams for mounting said at least one basket member on said first and second support beams.

12. The collapsible cart of claim 3 further comprising at least three wheels attached to said base panel.

13. The collapsible cart of claim 1 further comprising a plurality of mounting hooks attached to said first and second support beams for mounting said at least one basket on said first and second support beams.

14. The collapsible cart of claim 1 wherein said first support beam is slidable along the longitudinal axis of said first hinge pin and said second support beam is slidable along the longitudinal axis of said second hinge pin.

15. The collapsible cart of claim 14 wherein said first and second hinge mounts can block rotation of said first and second support beams around said first and second hinge pins when said first and second support beams are in a first position on said first and second hinge pins.

16. The collapsible cart of claim 15 further comprising:

a flexible cable connected between said first and second support beams; and

wherein movement of said cable can cause said first and second support beams to move along the longitudinal axis of said first and second hinge pins into a second position on said first and second hinge pins wherein rotation of said first and second support beams around said first and second hinge pins is allowed.

17. The collapsible cart of claim 16 wherein said at least one basket can be positioned to prevent movement of said first and second support beams along the longitudinal axis of said first and second hinge pins between said first position and said second position.

18. The collapsible cart of claim 1 wherein said base frame can block rotation of said first and second support beams in one direction.

19. The collapsible cart of claim 1 wherein when said basket support frame is rotated to a collapsed positioned said first and second support beams are positioned above and generally parallel to said base surface.

20. The collapsible cart of claim 19 further comprising at least one latch wherein said latch is capable of locking said basket support frame in said collapsed position.

21. The collapsible cart of claim 1 wherein said basket support frame further comprises a handle.

22. The collapsible cart of claim 1 further comprising a basket handle connected to said at least one basket.
