Next, the operation will be explained.

The distance between the front and rear wheels 7 is narrowed from a state in which the distance between the front and rear wheels 7 is wide, that is, a state in which the locking pin 5e provided on the bracket 5 is locked in the lower engagement hole 1d' of the support column 1. In this case, do the following:

First, the lever mounting seat 5a and the grip portion 5 of the lever 5C
The lever 5c is rotated counterclockwise in FIG. 4 by holding the lever 5c against the rotational biasing force of the spring 5h, thereby locking the locking pin 5e and the lower engagement hole 1d'. unlock.

Next, while holding the lever mounting seat 5a and the grip portion 5j, force is applied upward to move the entire bracket 5 upward to a position where the locking pin 5e and the upper engagement hole 1d match. , when the two match, loosen the clamping force, the spring 5h rotates the lever 5C clockwise, and the locking pin 5e locks with the upper engagement hole 1d,
Bracket 5 is held in the upper position.

As the bracket 5 moves upward, one end of the leg 6 moves upward together with the bracket 5, and the connecting rod 8 rotates upward around the connecting pin 1g with the terminal member 1e of the support column 1. rotates around a connecting pin 51 with the bracket 5.

As a result, the wheels 7 are drawn toward the support column 1, and as a result, the distance between the wheels becomes narrower, as shown by the two-dot chain line in FIG.

If you want to widen the distance between the wheels, just reverse the above procedure.

That is, the lever mounting seat 5a and the gripping portion 5j of the lever 5c are held together to release the locking pin 5e, and the entire bracket 5 is moved downward, so that the locking pin 5e is inserted into the lower engagement hole 1d'. All you have to do is lock it.

Next, the operation of the hand lever 9 will be explained.

First, when adjusting the height of the hand lever 9, the cylindrical member 10
is moved upward to disengage the upper end 1h of the support column 1 and the cylindrical body 10a, and the hand lever 9 is further tilted forward slightly to disengage the engagement pin 1a from the engagement hole 9b.

Next, after moving the hand lever 9 to a desired height, the hand push rod 9 is raised to lock the locking pin 1a in the desired engagement hole 9b,
Further, the cylindrical member 10 is moved downward to fit and lock the cylindrical body 10a to the upper end 1h of the support column 1.

As a result, the hand lever 9 is held at a desired height as shown by the two-dot chain line in FIG.

Next, when tilting the hand lever 9 forward, move the cylindrical member 10 upward in the same way as in the above case, and move the cylindrical body 10a and the support 1.
All you have to do is unfit it from the upper end 1h and just fold it forward.

As a result, the hand lever 9 is pushed forward toward the front of the vehicle as shown by the two-dot chain line in FIG.

Next, the operation of the chair 11 will be explained.

When using the chair 11, a person should be positioned behind the wheelbarrow and lower the tip 11g of the supporting leg 11b downward while pulling it toward the user.

As a result, the seat portion 11a rotates around its front end 11e and becomes horizontal.

In this way, the shopping cart of this embodiment is provided with four wheels 7 so that the cart can stand on its own and be pushed as it is, so even people with weak strength such as the elderly can use it easily.

In addition, the wheels can be opened and closed with a single touch, making it possible to narrow the distance between the wheels with a simple operation.Also, since the wheelbarrow can stand on its own, there is no risk of colliding with people in crowded places such as markets or in narrow aisles. You can run the wheelbarrow smoothly without any problems.

In addition, the chair 11 is attached so that it can be folded freely, so when you feel tired, you can sit on this chair 11 and take a rest.If you fold it up when you don't need it, it won't hit your feet when pushing the wheelbarrow, so it won't get in the way of running. It will never happen.

In addition, since the hand lever 9 is slidably attached, the height of the hand lever 9 can be adjusted according to the height of the user, and the hand lever 9 can be rotated forward, so that the chair 11 If the hand lever 9 hits your shoulder or the like when you sit down to take a break, you can tilt the hand lever 9 forward to prevent it from hitting your shoulder.

Furthermore, when the wheels 7 mentioned above are closed, the vehicle can be reclined slightly and used for walking while being pulled like a conventional two-wheeled shopping car. But it can be used without any resistance.

Furthermore, when the chair 11 is not needed, such as when used by young people, by removing the screw 3b of the chair support member 3,
Since the chair 11 can be easily removed together with the support member 3, this makes it even easier for young people to use it.

In this embodiment, a chair support member 3 is provided, and a chair 1 is attached to the chair support member 3.
1 is attached, but it is not limited to this and may be attached to the above-mentioned support column 1.

In this case, it goes without saying that the chair support member 3 is unnecessary.

As described above, according to the shopping cart according to the present invention, the legs for holding the wheels are rotatably attached to the brackets that are slidably fitted to the supports, and the locking pins provided on the brackets are attached to the brackets. The wheels can be opened and closed with a simple operation by engaging with the engagement holes on the top and bottom of the support, so the chair can be easily moved like a handcart even in crowded places, and the chair can be folded into a vehicle. Now that it's installed, you can sit on this chair and take a break when you're tired, and if you fold it up, it won't get in the way of your ride.
