Abstract
A collapsible shopping cart which can include a basket comprising a bottom surface, a front surface, a back surface wherein the bottom surface is rotatably coupled to the back surface, and the front surface is rotatably coupled to the bottom surface. There are also side surfaces that are rotatably coupled to the front surface and rotatably coupled to the back surface. The second side surface is rotatably coupled to the front surface and the back surface so that the front surface can be collapsed into the back surface. This device can also include a plurality of wheels and a gear system coupled to the basket for moving at least one of the wheels from a first position to a second position to allow the shopping cart to be collapsed into a closed form.
Claims12
A collapsible shopping cart comprising:
- a) a basket such that when said basket is in use it comprises:
- i) at least one bottom side;
- ii) at least one front side;
- iii) at least one back side;
- iv) wherein said at least one bottom side is rotatably coupled to said at least one back side, and said at least one front side is rotatably coupled to said at least one bottom side;
- and
- v) at least two side surfaces comprising at least one first side surface and at least one second side surface, wherein said at least one first side surface is rotatably coupled to said at least one front side and rotatably coupled to said at least one back side, and wherein said second side surface is rotatably coupled to said at least one front side and said at least one back side so that said at least one front side can be collapsed onto a position adjacent said at least one back side;
- and
- b) a plurality of wheels;
- and
- c) a gear system coupled to said basket for moving at least one of said plurality of wheels from a first position to a second position to allow the shopping cart to be collapsed into a closed form.
A collapsible shopping cart comprising:
- a) a basket such that when said basket is in use it comprises:
- i) at least one bottom side;
- ii) at least one front side;
- iii) at least one back side;
- iv) wherein said at least one bottom side is rotatably coupled to said at least one back side, and said at least one front rack is rotatably coupled to said at least one bottom side;
- and
- v) at least two side surfaces comprising at least one first side surface and at least one second side surface wherein said at least one first side surface is rotatably coupled to said at least one front side and rotatably coupled to said at least one back side, and wherein said second side is rotatably coupled to said at least one front side and said at least one back side so that said at least one front side can be collapsed into said at least one back side;
- b) a plurality of wheels;
- c) a translational gear system which includes a first gear and a second gear, that mesh together so that when said front side is moved relative to said back side, said first gear rotates and meshes with said second gear so that said second gear rotates, wherein said first gear rotates about a first axis and said second gear rotates about a second axis wherein said first axis and said second axis are offset from each other by approximately 90°;
- d) a first bracket coupled to said first gear, and disposed adjacent to said bottom side, said first bracket being rotatably coupled to said back side, and a second bracket that is coupled to said second gear and rotatably coupled to said back side wherein when said front side is moved relative to said back side, said bottom side moves with said front side causing said first bracket to rotate about an axis on said back side, causing said first gear to rotate about its axis which results in said second gear rotating in response to said first gear;
- and
- wherein at least one of said plurality of wheels is coupled to said second bracket such that when said first gear rotates, said second gear correspondingly rotates causing said second bracket to rotate causing said at least one of said plurality of wheels to move from a first orientation to a second orientation that is approximately 90° offset from said first orientation.
A collapsible shopping cart comprising:
- a) a basket such that when said basket is in use it comprises:
- i) at least one bottom side;
- ii) at least one front side;
- iii) at least one back side;
- iv) wherein said at least one bottom side is rotatably coupled to said at least one back side, and said at least one front side is rotatably coupled to said at least one bottom side;
- v) at least two side surfaces comprising at least one first side surface and at least one second side surface, wherein said at least one first side surface is rotatably coupled to said at least one front side and rotatably coupled to said at least one back side, and wherein said second side surface is rotatably coupled to said at least one front side and said at least one back side so that said at least one front side can be collapsed into said at least one back side;
- b) a plurality of wheels;
- and
- c) a translational gear means for rotating at least one of said plurality of wheels from a first position to a second position when said at least one front side is moved from a first position relative to said back side to a second position relative to said back side.
