Abstract

A cart includes: a chassis connected to a plurality of wheels; a basket mounted on the chassis and adapted to store one or more items therein; and a bridge element adapted to fit onto an edge of a vehicular trunk, wherein the bridge element is connected at a point located between said basket and said wheels.

Claims

1. A cart comprising:

a chassis connected to a plurality of wheels;

a basket mounted on the chassis and adapted to store one or more items therein; and

a bridge element adapted to fit onto an edge of a vehicular trunk, wherein the bridge element is connected at a point located between said basket and said wheels.

2. The cart of claim 1, wherein the bridge element is moveable on one or more rails connected underneath the basket substantially in parallel to a long axis of the basket.

3. The cart of claim 1, wherein the bridge element is moveable on one or more rails connected to the chassis substantially in parallel to a long axis of the basket.

4. The cart of claim 1, wherein the bridge element has a general shape of an upside-down U.

5. The cart of claim 1, wherein the basket extends forward relative to the chassis.

6. The cart of claim 5, wherein the bridge element is adapted to reach a position extending beyond the length of the chassis.

7. The cart of claim 1, comprising:

one or more wheels connected at a bottom of a front end of the basket, to smoothly glide the basket on a bottom of the vehicular trunk.

8. The cart of claim 1, wherein the chassis comprises:

a first set of one or more collapsible beams, connecting a right side of the basket with a right side of the chassis; and

a second set of one or more collapsible beams, connecting a left side of the basket with a left side of the chassis.

9. The cart of claim 8, wherein the first set of collapsible beams comprises one or more pivot brackets able to collapse said first set of collapsible beams;

and wherein the second set of collapsible beams comprises one or more pivot brackets able to collapse said second set of collapsible beams.

10. The cart of claim 8, wherein at least one of the first and second sets of collapsible beams is connected through to a pullable cable adapted to collapse said at least one set of collapsible beams upon pulling of said cable.

11. The cart of claim 10, wherein an end of the cable is connected to a handle adapted to be pulled by a hand of a human being.

12. The cart of claim 11, wherein the cable passes through a one-way roll-up mechanism adapted to maintain the cable partially pulled upon release of said handle.

13. The cart of claim 9, wherein a height of the basket from the ground is user-modifiable by modifying an angle of one or more of the pivot brackets.

14. The cart of claim 13, comprising:

a multi-step locking mechanism adapted to lock the height from the ground of the basket at a particular height set by a user.

15. The cart of claim 14, wherein the multi-step locking mechanism comprises:

a set of ratchets; and

a sliding pole, adapted to be moveable along a downward direction along said set of ratchets, and adapted to be unmovable along an upward direction along said set of ratchets.

16. The cart of claim 15, wherein the multi-step locking mechanism is lockable to disallow folding of the chassis, and is unlockable to allow folding of the chassis.

17. The cart of claim 1, wherein the basket is detachably attached to said chassis through one or more connectors.

18. The cart of claim 17, wherein the chassis comprises an extendable rail;

and wherein the basket is adapted, upon its release from said chassis, to glide along said extendable rail into said vehicular trunk.

19. The cart of claim 18, comprising:

one or more wheels connected at a bottom of a front end of the basket, to smoothly glide the basket on a bottom of said vehicular trunk.

20. The cart of claim 1, wherein one or more rails are connected underneath the basket and are connected to said bridge element;

wherein the basket is detachable from the chassis; and

wherein the basket is forward-movable along said one or more rails and relative to said bridge element when said bridge element is positioned over the edge of said vehicular trunk.
