Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a trolley with a frame used at a supermarket counter or the like.

[0002]

[Prior art]

 Framed trolleys are mainly used in supermarkets and distribution center workshops, but they are used more frequently in supermarkets for replenishment or display. The appearance of the trolley with a frame used for this purpose is regarded as important because it not only fulfills the functional aspects but also touches the eyes of customers.

FIGS. 6 and 7 show a conventional example of a truck with a frame. In the drawings, a is a truck body, b is a top member of the truck body a, c is a plurality of casters mounted on a lower surface of the truck body a, d is a frame receiving member having a rectangular cross section attached to the front and rear portions of the truck body a, e is a bumper rubber attached to each frame receiving member d, and f is a top member b just above each frame receiving member d. The perforated frame insertion holes, g is a pair of inverted U-shaped frames, h is a reinforcing material that reinforces the lower portions of both legs of the frame g from inside, and j is mounted on the inverted U-shaped frame g in multiple stages. The shelf receiving member, k is a shelf, and the lower ends of both legs of a pair of inverted U-shaped frames g are inserted into each frame receiving member d, and the shelf k is hung over the shelf receiving member j, and The product is placed on the main body a and the shelf board k, and is used for replenishing the product or displaying the product at the supermarket. The bogie main body a and the top member b are made of a plastic material so as to easily remove dirt and the like. For the inverted U-shaped frame g, a rectangular pipe made of a steel material is used, and the surface thereof is painted.

[0004]

[Problems to be solved by the invention]

 As described above, the conventional trolley with a frame uses a rectangular pipe made of steel material for the inverted U-shaped frame g and paints its surface, so if it hits an object during work, the coating film peels off. As a result, rust is generated and the appearance is impaired, which is not preferable as a bogie used in a supermarket counter or the like.

[0005] As a countermeasure for preventing rusting of the inverted U-shaped frame g, a stainless steel rectangular pipe may be used instead of a steel rectangular pipe. However, a stainless steel rectangular pipe is expensive. It is appropriate to use an inexpensive round stainless steel pipe g '(see FIG. 8). In this case, it is necessary to use a large-diameter stainless steel round pipe to secure the same strength as a steel rectangular pipe, but the large-diameter stainless steel round pipe is not The stainless steel round pipe (refer to D in FIG. 8) having a relatively small diameter that matches the inner dimensions of the frame body receiving member d has to be used without entering the frame body receiving member d attached. The strength of the inverted U-shaped frame g cannot be sufficiently secured. In addition, a large gap (see FIG. 8E) is formed between the frame receiving member d and the inverted U-shaped frame g, which causes a problem that the inverted U-shaped frame g becomes unstable in the front-rear direction. .

[0006] The present invention is proposed in view of the above problems, and a purpose thereof is to provide a bogie with a frame that can achieve both rust prevention, strength retention, and stable support of an inverted U-shaped frame. The point is to provide.

[0007]

[Means for Solving the Problems]

 According to the present invention, in order to achieve the above object, frame receiving members having a rectangular cross section are provided on the front and rear portions of the bogie main body, and lower portions of both legs of a pair of inverted U-shaped frames are inserted into the respective frame receiving members. The inverted U-shaped frame comprises a stainless steel round pipe having a relatively large diameter, wherein the inverted U-shaped frame is formed of a stainless steel round pipe having a relatively large diameter. The lower parts of both legs are formed in an oval cross section, and a small gap is formed between the front and rear outer surfaces of the lower parts of the legs and the front and rear inner surfaces of the frame receiving member. It is characterized in that the inner dimensions in the left-right direction are substantially the same.

[0008]
