Description

[Detailed description of the invention] [Industrial application field] This invention is a chair that can be used as a walking aid for people with weak legs such as elderly people or physically disabled people who have difficulty walking, and as a resting chair while walking. Concerning a shopping cart that can be used as a shopping cart.

[Prior art and its problems]

Various types of shopping carts are already known that can be used by people with weak legs or mobility issues, such as the elderly or physically disabled, as walking aids or as chairs for resting while walking. ing.

Generally, these handcarts are equipped with a push rod and are equipped with a basket-shaped article storage body for storing goods, and the top opening of this basket-shaped article storage body is made of a hard plate or the like. It has a structure with a cover plate that doubles as a seat plate, and the user receives walking assistance by holding on to the push rod, and if he or she needs to take a break while walking,
The structure is such that the user can take a rest by sitting on a lid plate that is formed on the top surface of the basket-shaped article storage body and also serves as a seat plate.

However, in these known handcarts, a lid plate made of a flat plate-like body that also serves as a seat (seat plate) is simply attached to the upper opening of the article storage body so that it can be opened and closed, and it also serves as a seat. Because there was no special structure attached to the periphery of the cover plate, when the user sat on the cover plate surface, the area around the waist could not be stably held, and the user's lower back (buttocks) could not be held securely when sitting on the cover plate. It has been pointed out that the problem is that it causes a feeling of uneasiness as it slides laterally, giving an extremely unstable feeling of use.

In addition, people who use such handcarts have weak legs, so it would be easier if they could grab onto some kind of aid when trying to stand up from the cover plate, which also serves as a seat. However, it has been pointed out that the above-mentioned conventional structure has the disadvantage that it is difficult for the user sitting on the lid plate to stand up because there is no structure for the user to grasp when trying to stand up. was.

[Purpose of invention]

In view of the above-mentioned circumstances, the present invention attempts to cope with this problem by attaching a seat frame to the upper end of the article storage body and integrally forming a handrail rod upright on the seat frame. It is an object of the present invention to provide a seat frame for a shopping handcart in which the handrail can be used as a standing aid for the user when the user stands up.

Another object of the present invention is to provide a seat frame for a shopping cart, in which the entire seat frame is formed to have an excellent appearance in terms of design, and is also constructed as a structure with excellent strength. This is what I am trying to do.

[Key points of the idea]

The present invention provides a shopping cart configured to attach an article storage body with an open top surface,
The periphery of the opening of the article container is attached to a U-shaped floor frame attached to a shopping cart, and the upper end of the article storage body is attached to both side walls of the seat frame. The key point of the invention is the structure of the seat frame of a shopping cart in which the handrail rods are integrally erected so that the distance is wider than the distance between the side walls of the floor frame.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

The shopping cart of the present invention has wheels 3, 3 on the lower end.
The front leg rods 1, 1 equipped with wheels 3, 3 at the lower ends and the rear leg rods 2, 2 equipped with wheels 3, 3 at their lower ends are foldably combined to form an X-shape on the side via several connecting rods 4...4. , hand lever 5 at the upper end of the front leg lever 1,1
The frame is constructed by foldably connecting the front leg levers 1, 1 and the upper ends of the rear leg levers with U-shaped frame levers 11, 11.

Reference numeral 6 denotes an article storage body suspended inside the part surrounded by the frame composed of the front leg levers 1, 1 and the rear leg levers 2, 2, and is shaped like a square bottom bag with an open top surface. The peripheral edge of the opening is attached to the peripheral edge of a seat frame 7 having a U-shape in plan and positioned on the upper surface thereof.

Note that the seat frame 7 may also have an accessory case 72 integrally formed at its rear end.

The lower end of the seat frame 7, which integrally forms the accessory case 72, is fixed to a U-shaped frame rod 11 attached to connect the upper ends of the front leg rods 1, 1 and the rear leg rods 2, 2. .

The seat frame 7 is formed into a rectangular frame shape using a synthetic resin having an appropriate hardness, and has wall surfaces with an appropriate height protruding from three sides excluding the front edge in a U-shape in plan. These walls surround the lid plate 8 and support the user's waist.

The cover plate 8 has a side surface thereof, a side wall 71 of the seat frame 7,
The cover plate 8 is attached so as to be able to stand up freely via the links 10, 10, etc. extending between the cover plate 71 and the cover plate 8, and the cover plate 8 can also be attached so that both sides can be turned over as required.

When the front and back sides of the lid plate 8 are made reversible,
It is often the case that one side of the cover plate 8 has a lid function, and the other side is used as a seat surface for the user to sit on. It can maintain a clean and clean condition.

Reference numerals 9, 9 are handrail rods that stand upward from side walls 71, 71 located on both sides of the seat frame 7 formed in a U-shape in plan, and the interval between the two opposing handrail rods 9, 9 is is the side wall 7 that constitutes the seat frame 7
It is set to be slightly wider than the width of 1.71.

The distance between the handrail rods 9, 9 is set such that the lower back of the user sitting on the surface of the cover plate 8 is not obstructed by the handrail rods 9, 9, and the height thereof is set to It is desirable to set the height to be appropriate for the user to grasp the upper end when standing up.

In the illustrated embodiment, the handrail rods 9 are erected from the upper ends of the side walls 71, 71 so as to form an inverted V-shape when viewed from the front, but the means for raising the handrail rods 9 is not limited to this. For example, a handrail rod (not shown) may be formed by standing up in an inverted V-shape at an appropriate height from the outside of both sides of the side walls 71, 71, or bent into a front L-shape from the side surfaces of the side walls 71, 71. ) can be installed by any means such as standing up.

Further, the shape of the handrail rod 9 is not necessarily limited to the illustrated example; for example, the shape of the handrail rod body may be formed into a biased circular shape (horizontally long circular shape), and the lower portions of both ends of this circular shape may be used for attachment. It is possible to form it into various desired shapes, such as a shape with protruding legs.

Further, the structure of the handcart main body is not limited to the structure of the illustrated embodiment, but any structure capable of accommodating the article container 6 suspended from the seat frame 7 on the inside of the main body can be used. Of course, anything is acceptable.

Further, the mounting structure of the cover plate 8 is not limited to the structure of the illustrated embodiment.

The effects of the present invention configured as described above are as follows.

(1) Since the seat frame 7 is formed into a U-shape in plan, the user's lower back is stably supported around it by the seat frame 7 and does not move excessively from side to side. It has been possible to eliminate the instability associated with side-to-side movement that the seat board of conventional shopping carts had.

In addition, the present invention has a seat frame 7 formed in a U-shape in plan view.
Since the handrail rods 9, 9 are integrally formed on the side walls 71, 71, when a user sitting on the cover plate 8 tries to stand up from the surface of the cover plate 8, he or she can stand up while grasping the handrail rods 9, 9. This has the advantage that even paper users with weak legs can easily stand up because they can make movements.

(2) When the handrail rods 9, 9 are vertically erected from the side walls 71, 71, since the handrail rods 9, 9 stand in close contact with the sides of the user's body,
In order to stand up, problems arise such as it is difficult for the user to insert his/her hand between the user's body and the user's body in order to grasp the handrail rods 9, 9. However, as described above, the present invention Side wall 7 of seat frame 7
