The (CCS) is attachable to a car's tow bar (10), and can be taken home, to a shop, etc., or left on the tow bar (10) for next use. The (CCS) is intended for private use and for stores.
In one embodiment, the (CCS) comprises a top beam (1) with a “U” shape, having a bottom (2) and two ends (3) on the left and right sides, wherein said bottom and ends each have a hole for clamping a ball joint (5) on the upper ends (3), and an electric jack (12) on the bottom of the beam (2), and so that the ball coupling bottom (4) is attached between the three beams (1 and 2), such as with two screws (8), and two annular disks (7), as shown in Fig.1.The top beam (1) further has holes (9) on the left and right sides, to attach an extra cable, as shown in Figs.1 and 2. The electrical jack (12) is attached under the upper beam (1). The electric jack (12) has a top (13) and a bottom (14), the jack's top and bottom (13 and 14) each having at least one hole (6) for attaching the bottom (2) of the top beam to the top (13) of the jack, and a lower middle beam (15) to the bottom (14) of the jack, as shown in Figs.1 and 2. The lower middle beam (15) has a left end (16) and a right end (17), each end having a hole (6) for attaching a hinge (33), as shown in Figs.1 and 2. A hook (27) is attached on the outside of each end (16 and 17), as shown in Figs.
2, 4, and 5. The lower beams (18 and 19) are attached to the ends of the lower middle beams (16 and 17), to the left (18), and to the right (19), as shown in Fig.2. Said left and right lower beams (18 and 19) each have two ends, one inner end (20 and 22), and one outer end (21 and 23), each inner end (20 and 22) having at least one hole (6) for attaching to both ends (16 and 17), and so that end 16 is attached to end 20 and end 17 is attached to end 22, such as with a screw (8) and a annular disk (7), and so that both lower beams (18 and 19) are folded out when loading on the cart (38 or 28), and folded in when the assembly is not in use, as shown in Figs.2, 4 and 5.
A hook (27) may be attached to the outer side of each end (21 and 23), to secure belts or cables (25). Said belts or cables (25) have holes (26) on their ends, the holes being attachable to the hooks (27) that are attached to all (4) external ends (16,17,21 and 23) of all three lower beams (15, 18 and 19), in order to hold the cart (38 or 28) securely while driving, as shown in Figs.2, 4 and 5.
When the electric jack (12) is lowered, all lower beams (15, 18 and 19) are lowered with the cart (38 or 28), and said elements are lifted when the electric jack (12) is raised, as shown in Figs.4 and 5.
The collapsible shopping cart (38), which can be folded together and folded out, is configured for attachment to the lower beams (15, 18 and 19) of the (CCS).
The collapsible shopping cart (38) can be made of any material, hard or soft. The cart (38) can be brought for instance home, or to a store, or it can be left on the jack assembly, optionally on a tow bar (10). It can also be stored, with the assembly or separate from it, in for instance a boot of a car (36). It is suitable for private use as well as for use by stores.
In one embodiment, the collapsible shopping cart comprises at least five horizontal beams (29); two upper, two lower and one centre beam, as shown in Fig.3, each outer end of each horizontal beam (29) having a hole to which a hinge (33) can be attached, as shown in Fig.3. At least four middle beams (30) -are attached on the inner sides of the horizontal beams (29), such as two on the top and two on the bottom, each middle beam (30) comprising two halves, and each half beam having two holes (6) on its left and right ends, for attaching hinges (33), as shown in Fig.3. Two vertical beams (31) are attached to the left and the right side of the cart (38), one at the front and one at the back, each vertical beam (31) having two ends, one at the top at one at the bottom, and each end has a hole (6) for attaching a hinge (33), as shown in Fig.3. A handle (32) is attached to the rear of the two rear middle beams (30) and the two vertical beams (31), said handle (32) being divided into two halves, each half beam having two holes, on its right and left sides, for attaching a hinge to each hole, as shown in Figs.3, 4 and 5. Two shafts (34) are attached below the three lower horizontal beams (29) and the two lower middle beams (30), each shaft (34) also being divided into two halves, each half shaft having two holes (6), on the right and the left sides, for attaching a hinge (33) to each hole (6), as well as two holes (6) on the outer ends of each entire shaft (34), for attaching wheels, as shown in Fig.3.
In a further embodiment, the beams (29, 30, 31), the handle (32), the hinges (33), the shafts (34), and the wheels (35) are all attached with a screw (8) and an annular disk for each hole, as shown in (Fig.3).
In order to use the collapsible cart (38), a user may pull one of the two upper horizontal beams (29) towards themselves. The remaining beams (29, 30, 32), the handle (32), and the shafts (34) with the wheels (35) will then simultaneously fold out via the hinges (33), as shown in Fig.4. In order to fold together the collapsible cart (38), a user may press one of the two upper horizontal beams (29). The remaining beams (29, 30, 32), the handle (32), and the shafts (34) with the wheels (35) will then simultaneously fold together via the hinges (33), as shown in Fig.5.
When finished using the jack assembly and optional collapsible cart (38), the lower beams (18 and 19) may be folded together under the lower beam 15, and the entire assembly, optionally with the collapsible cart (38), can be removed using the ball joint (5). Both fit in a boot of a car (36) for storage. The jack assembly and optionally the cart may also be left on the car's tow bar (10). See Figs.4 and 5.
In one embodiment, the (CCS) is operatable by a method comprising:
A. activating the jack, such as by clicking a button, so that the jack (12) lowers with all of the lower beams (15,18 and 19) simultaneously, as shown in Fig.2;
B. placing the collapsible cart (38 or 28) on these lower beams (15,18 and 19), and behind the car's trunk (36) and bumper (37), as shown in Fig.4;
C. optionally fastening the cart (38 or 28) with belts (25) in the hooks (27), as shown in Fig.5;
D. activating the jack, such as by clicking the button again, so that the jack (12) lifts all of the said lower beams (15, 18 and 19) with the whole cart (38 or 28) and any load in the cart simultaneously, as shown in Fig.4;
E. driving the car with the cart (38 or 28) attached to the back of the car, as shown in Fig. 4;
F. after driving to the desired destination, lowering the jack (12) with all the lower beams (15, 18 and 19) and the cart (38 or 28) simultaneously, as shown in Figs.2 and 4.
The cart (28 or 638) may then optionally be wheeled into a home, elevator, etc. and emptied, thus saving time, and saving a user from carrying the goods.
When the collapsible cart 38 is empty, the horizontal beams (29) of the cart may easily be pulled towards each other so that the middle beams (30), the vertical beams (31), the handle (32), the shafts (34) and the wheels (35) of the cart all are closed simultaneously towards each other through the hinges (33), as shown in Fig.5.
The cart can be stored or attached again to the car, ready for the next trip, as shown in Fig.5. When completely finished using (CCS), close both lower beams (18 and 19) below the lower beam (15), and remove the entire ((CCS)) with cart (38 or 28), and store it in the boot (36), or leave it on the tow bar (10) and in front of the bumper (37), as shown in Fig. 5.
