Description

Three-wheeled shopping cart with adjustable height of loading plate

The present invention relates to a shopping cart, and more particularly, when the user presses a pedal installed at the bottom of the shopping cart with a foot, the user can lean the waist by adjusting the height of the bottom of the shopping cart by the hydraulic device. It is related to a shopping cart that can be loaded and unloaded without a load, and also makes it easier to change directions by attaching a front wheel composed of ball wheels and a three wheel composed of two rear wheels.

In general, a shopping cart refers to a small cart for shopping, and is used when shopping in a department store or a large mart (see FIG. 1).

Customers who use the shopping cart (or sometimes referred to as a 'cart') lean down when loading an empty cart. At this time, if the customer buys a fragile object or a small object, the lower back of the cart should be deep enough to reach the hand. In particular, those who are tall or have short arm lengths need to bow their backs a lot, and young children or short people often throw or drop things because they are out of reach because of the basket height of the cart.

Also, after shopping, you will have to put your cart back on the counter to check in. Even in this case, the items loaded on the cart have to be put down on the checkout counter and the power is long and takes a long time.

Next, a conventional shopping cart will be described with reference to the accompanying drawings.

1 is a perspective view showing a state of a conventional general shopping cart 10.

The shopping cart 10 is composed of a rectangular wire mesh and the shopping basket 11, the handle 12 is formed on one side, the support frame 13 for supporting the shopping basket 11, and the support frame 13 Consists of four wheels 14 installed at the bottom of the).

The shopping cart 10 is uncomfortable to load or take things out by lowering the waist, it is composed of four wheels had a problem that it is difficult to change the direction when a lot of weight by the loaded goods.

In order to solve this problem, conventionally, the shopping cart 20 that can adjust the height as shown in FIG.

The conventional shopping cart 20 illustrated in FIG. 2 has a loading box 21 having a handle 22 attached to one side thereof, and a bellows shape configured at a lower portion of the loading box 21 to adjust the height of the loading box 21. It consists of a support frame 23 and four wheels 24 provided at the lower end of the support frame 23.

The shopping cart 20 is to adjust the height of the stacking box 21 while the user pushes down or pulls up the handle 22 and the bellows-type support frame 23 is opened and folded. have.

However, the shopping cart 20 has a disadvantage in that a lot of force is required because the user is configured to adjust the height of the stacking box 21 by holding or pressing the handle 22. In addition, in the case of women who mainly use the shopping cart 20, there is a problem that is more inconvenient and difficult to use because of the weight of the object loaded in the loading box (21).

In addition, the shopping cart 20 is difficult to use and inconvenient as well as difficult to adjust the height desired by the user to move the heavy cart itself using only the arm force up and down.

Moreover, the shopping cart 20 has a disadvantage that the support frame 23 made of bellows is easily broken. That is, when the shopping cart 20 is used for a long time, the bellows loses its elastic force, and when the bellows go up by itself or put an object in the loading box 21, the bellows are folded and go down by itself.

In addition, the shopping cart 20 is composed of the support frame 23 of the bellows shape at the bottom, there is a disadvantage that can not be stored in a plurality of shopping carts.

3 is a perspective view showing another conventional shopping cart.

The conventional shopping cart 30 shown in FIG. 3 constitutes a vertical handle 33 formed vertically on both sides of the handle 32 in order to make it easier for a user to change the direction of the wheel 35.

However, since the shopping cart 30 has to move in a vertical direction, it is inconvenient because more force must be applied as compared to the horizontally configured handle 32.

In addition, the shopping cart 30, the vertical handle 33 is formed to protrude perpendicularly to the handle 32, there is a risk of injury when you lean the waist to take out the goods, people who pass when shopping is injured There is a risk of getting dressed or clothes.

As such, the conventional shopping cart has the inconvenience of loading or taking out the goods by bowing the waist, it is difficult to change the direction when a lot of weight of the loaded goods. If a shopping cart is made to make shopping more convenient in life, it will be preferred to the existing cart.

The technical problem to be achieved by the present invention in order to solve the above problems is to provide a shopping cart that can be easily loaded and taken out to the shopping cart without lowering the waist by adjusting the height of the shopping cart loading plate.

In addition, another technical problem to be achieved by the present invention is to provide a shopping cart for adjusting the height of the shopping cart loading plate without using a motor power source.

In addition, another technical problem to be achieved by the present invention, to adjust the height of the shopping cart loading plate can be easily loaded and taken out to the shopping cart without bowing, the front wheel uses a three-wheel wheel consisting of a ball caster It is to provide a shopping cart that can be easily changed direction.

In addition, another technical problem to be achieved by the present invention is to provide a shopping cart that is easy to change direction and ensure stability because the three wheels move independently.

In addition, another technical problem to be achieved by the present invention, the hydraulic device used to move the loading plate of the shopping cart up and down is located on the side of the back of the shopping cart that can be stacked several shopping carts as conventionally To provide a cart.

In addition, another technical problem to be achieved by the present invention is to provide a shopping cart that can be easily adjusted by the user in the foot rest by installing a footrest to adjust the height of the shopping cart loading plate in the lower rear side of the cart. .
