One shopping cart is manufactured by bending the front end portion 60a of the inserted bottom receiving net 60 to be substantially parallel to the mounting plate 51 in order to prevent the 60 from coming off.

[0006]

[Problems to be solved by the invention]

 However, the above-mentioned conventional shopping cart has the following problems in manufacturing because the frame member and the basket member are all welded in manufacturing a cart frame with a basket. That is, when the members are sequentially welded, such as by welding the support frame 56 to the bogie frame 52, the overall shape gradually increases. Therefore, when welding by robot welding or the like, the welding device itself must be large. There was a problem that it had to be done.

After the cart frame with a basket is manufactured as described above, the front end 60a of the bottom receiving net 60 is manually bent when the bottom receiving net 60 is attached. Since it is made of a durable metal wire, such bending work is extremely labor-intensive and burdens manufacturing.

The present invention has been made in view of the above-mentioned conventional problems. In manufacturing a cart frame with a basket, a welding device smaller than a conventional welding device used for manufacturing a shopping cart is used. A first object is to provide a shopping cart having a structure that can be manufactured by using the shopping cart.

[Embodiment of the invention]

 Hereinafter, an embodiment of a shopping cart according to the present invention will be described with reference to necessary drawings as needed.

1 and 2, reference numeral 1 denotes a shopping cart main body including a frame member, a basket member, wheels, and a bottom receiving net. The frame member includes a bogie frame 2 provided with wheels below, a column frame 3 fixedly mounted to the rear end of the bogie frame 2, and a support frame 5 supporting a basket 9 from below. .

More specifically, the bogie frame 2 is formed by, for example, bending a metal pipe into a substantially U-shape in plan view, and its rear ends 2a, 2a are crushed flat. Thus, a joint 4 is formed, and two holes 4a for screw insertion are formed in the joint 4 at two places.

As shown in FIG. 3, a pair of mounting pieces 6 and 6 are provided on the front end 2 b of the bogie frame 2 so as to face inward. A hole (not shown) for inserting a screw into which a shaft of a screw member such as a bolt can be inserted is formed.

Further, the mounting pieces 6, 6 of the bogie frame 2 are provided with an insertion hole 8 into which the front end 23 a of the bottom receiving net 23 can be inserted and a screw insertion hole 1 into which a shaft of a screw member such as a bolt can be inserted. A mounting plate 10 having holes 0a and 10a is removably fixed by screwing a screw member such as a bolt and a nut.

The mounting piece 6 and the mounting plate 10 are screwed and fixed using the bolt shafts of the front wheels 20, 20, and the front wheel 20, the mounting piece 6, and the mounting plate 10 are integrated. The front wheels 20, 20 are omitted in FIG. 3 (the front wheels 20, 20 are omitted in FIG. 3).

Next, the support frame 3 is formed, for example, by bending a metal pipe into a substantially inverted U-shape in a front view, and the upper side thereof is a handle portion 11. As shown in FIG. 4, a pair of flat joints 12, 12 that sandwich the joint 4 of the bogie frame 2 protrude near the lower end 3 a of the support frame 3. The connecting member 14 is fitted around the connecting member 14, and the connecting member 14 is fixed to the vicinity of the lower end 3a of the support frame 3 by means such as welding.

In a state where the joined portions 12 of the connecting member 14 are sandwiched between the joining portions 4 of the bogie frame 2, the two are fixed to each other by a screw member such as a bolt and a nut. That is, the rear end portion 2a of the bogie frame 2 and the vicinity of the lower end portion 3a of the column frame 3 are fixed by screws via the connecting member 14, and the column frame 3 stands upright on the bogie frame 2.

The joined portion 12 of the connecting member 14 is partially extended on the lower side, and the extended portion is locked as a locking portion 15 that can lock a hanging tool such as a hanging wire. A hole 15 is drilled.

The rear wheels 21, 21 are fixed to both lower ends 3a, 3a of the support frame 5 with screws using bolt shafts of the rear wheels 21, 21, respectively.

Next, the support frame 5 is formed, for example, by bending a metal pipe into a substantially inverted U-shape in a front view, and the basket 9 is placed on the upper end 5 a thereof. The support frame 5 is fixedly mounted at an intermediate portion of the bogie frame 2 by means of welding or the like and stands upright.

The basket 9 has, for example, a net-like body made of a thin metal wire formed in a box shape so as to accommodate goods and the like, and has a substantially L-shaped front view on the lower surface of the middle portion 9 b of the basket 9. The backing plates 30, 30 are fixed. In the basket 9, the backing plates 30, 30 are placed on the support frame 5, and the rear end 9 a of the basket 9 is fixed to the middle portion 3 b of the support frame 3 by means such as welding.

As shown in FIG. 5, a holding member having a plate-like body formed in a substantially Ω shape in a front view is provided below the backing plate 30 so as to hold the upper end 5 a of the support frame 5. The member 16 is fitted. A screw member such as a bolt nut is attached between both hem portions 16a, 16a of the holding member 16 and the backing plate 30, and the support frame 5 and the basket 9 are fixed by screws.

Reference numeral 23 denotes a bottom receiving net provided inside the bogie frame 2. The bottom receiving net 23 is formed by arranging metal wires vertically and horizontally and welding each intersection to form a lattice. The front end 23a is inserted into the insertion hole 8 of the mounting plate 10 (see FIG. 3). The front end portion 23a is formed by bending a metal wire downward at a substantially right angle in advance and again substantially in parallel with the bogie frame 2, and the front end portion 23a of the bottom receiving net 23 is attached to the mounting plate 10 by the bending. Locked irremovably.

The shopping cart has a configuration in which the trolley frame 2 and the support frame 3 and the support frame 5 and the basket 9 are fixed by screws, so that the support frame 5 is welded to the trolley frame 2 in advance, and Since the welding work is not performed when the basket 9 is welded to the frame 3 and the two are fixed, there is no need to use a large welding device when manufacturing the shopping cart.

That is, in order to weld the bogie frame 2 with the support frame 5 and the support frame 3 with the basket 9, a large welding device must be used (note that the support frame 5 is welded to the bogie frame 2). In this case, a relatively small welding device is sufficient for the welding operation.) The bogie frame 2 with the support frame 5, the supporting frame 3 with the basket 9 and the basket 9 and the bogie frame 2 are fixed by screws. According to the shopping cart according to the present invention, it can be manufactured using a relatively small welding device as compared with the related art.

The mounting plate 10 into which the front end 23a of the bottom receiving net 23 is inserted is not a structure that is fixed to the bogie frame 2 in advance, but the mounting plate 10 is attached to and detached from the bogie frame 2 by screws or the like. The front end 23a of the bottom receiving net 23, whose front end 23a is bent in advance, is inserted into the insertion hole 8 of the mounting plate 10 so that the mounting plate 10 with the bottom receiving net 23 can be fixed. Is attached to the mounting piece 6 of the bogie frame 2, so that the bottom receiving net 23 is irremovably mounted inside the bogie frame 2. Therefore, it is not necessary to manually bend the front end of the bottom receiving net when attaching the bottom receiving net as in the related art, and the bottom receiving net can be easily attached.

Further, since the connecting member 14 provided with the locking portion 15 capable of locking a hanging tool such as a hanging wire is fixed to the support frame 3, the cart frame with the basket is manufactured after the manufacturing. The hanging member can be locked to the connecting member 14 when the cart frame with the basket is immersed in a paint tank so as to be painted.

In the above-described embodiment, a bolt nut is used as an example of a means for fixing each member by screwing. However, what is fixed by using a screw or a rivet is also included in the meaning of fixing by screwing.

Further, the shopping cart in the above embodiment is merely an example, and the design can be changed as appropriate within the range intended by the present invention.

[0034]

[Effect of the invention]

 As described above, since the shopping cart according to the present invention has a structure in which the bogie frame and the support frame are fixed by screws, the shopping cart is smaller than the conventional welding device used for manufacturing a shopping cart. It can be manufactured using a welding device of the type described above.

Further, since the shopping cart according to the present invention has a structure in which the support frame and the basket are fixed by screws, the welding cart is smaller than a conventional welding device used for manufacturing a shopping cart. It can be manufactured using equipment.

As described above, according to the structure of the shopping cart according to the present invention, since the shopping cart can be manufactured with a small welding device, the productivity can be improved and the cost of the shopping cart can be reduced. .

Further, if a mounting plate for detachably securing the front end of the bottom receiving net is removably fixed to the front end of the bogie frame, the mounting plate is locked for the bottom receiving net to be unremovable. Can be fixed to the bogie frame, and there is an advantage that the work of bending the front end of the bottom receiving net can be omitted when the bottom receiving net is attached as in the related art.
