Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shopping car with a bag, and more particularly to a shopping car with a bag that can be folded down to the size of a shopping bag.

[0002]

2. Description of the Related Art Recently, young and old people prefer smart shopping cars rather than silver cars, and this is gaining in popularity. As small shopping carts, two-wheel or three-wheel shopping cars are on the market, but in terms of stability, four-wheel shopping cars are superior.

[0003] However, the biggest drawback of the conventional four-wheeled shopping car is that it does not become smaller when folded. Of course, there are some conventional ones that can bring the front wheel and the rear wheel closer, or can narrow the front wheel and the rear wheel to be folded. However, there is no conventional shopping car whose height is reduced to the size of a bag. In this regard, the shipping car disclosed in Japanese Utility Model Laid-Open Publication No. 4-38879 can be folded to the size of the carry light, but the axle spacing is narrow and cannot be pushed by simply pulling. Has the disadvantage of doing so. On the other hand, the wheelbarrow disclosed in JP-A-64-36565 is a shipping car that can be pushed, but cannot be folded with a large amount of luggage.

[0004] In order to reduce the height when folded, the prior art of raising the wheel to the bag is disclosed in Japanese Patent Laid-Open No. 3-1.
No. 6,875, and JP-A-4-252770. However, JP-A-3-16875
The gazette disclosed in the publication relates to a luggage carrier when a base extended by two wheels is folded.
Therefore, it is not applicable to a shopping car with a bag as in the present invention. Also, Japanese Patent Application Laid-Open No. Hei 4-25277
In Japanese Patent Publication No. 0, there is a baby carriage and a folding mechanism used therein. However, since it is a mechanism in which the front wheel and the rear wheel are narrowed and folded, it is not applicable to the shopping cart with a bag of the present invention.

[0005] That is, although the shipping car has a detachable bag, many people actually take the trouble to remove the bag. Therefore, when carrying a shopping car into a car or the like with a bag full of shopping and a large amount of luggage attached thereto, the shopping car main body can be folded down to the same size as the bag, and furthermore, it is pushed. However, there is no shopping cart with a bag that fulfills such a purpose.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention allows a large amount of luggage to be stored in a bag, folds the bag to the same size as the bag, and allows a large distance between the vehicles to be pushed by hand. The purpose is to provide a shopping car with a bag.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a support rod pivotally supported by a handle rod, the support rod pivotally supporting a front leg rod, and the other end includes a front leg loading rod and a rear leg. The upper ends of the leg loading rod and the intermediate loading rod are pivotally supported, the front leg rod is pivotally supported with the rear leg rod, and the lower end of the intermediate loading rod is pivotally connected to the middle of the front and rear intermediate rods that are folded in two when folded. The lower ends of the front and rear luggage bars are pivotally supported by a carriage with a slit groove for loosely fitting the front and rear luggage bars, and both ends of the front and rear intermediate rods are connected to the front and rear legs via the slit grooves. When connected to the lower end of the leg rod, a bag is arranged between the loading rod members, and when the handle rod is folded down and folded, the front and rear leg rods are pushed down by the front and rear wheel rods through the slit grooves, and the front and rear wheels are lowered. , Lift the vertical cylinder with the front and rear legs and move the shopping cart It is obtained by a shopping cart that can be folded reduced to size.
