Both side edge edges of the wheel insertion port 5a are inclined so that the width of the portion facing the boundary with the outer plate 8 is narrowed in order to prevent the corrugated cardboard from being torn.

The fixing member 4 is composed of a crosspiece 14 corresponding to the inner dimension of the tray 3 in the length direction and a crosspiece 15 corresponding to the inner dimension of the tray 3 in the width direction. When assembling the tray carriage, the crosspiece 14 is formed. 5 blanks are used, and 2 blanks of the crosspiece 15 are used.

The crosspiece 14 has a long plate shape, and two sets of cut grooves 14a for meshing with the crosspiece 15 are inserted in the long end edge above the crosspiece 14, one long and one short. Further, an engaging projection 14b for fixing to the tray 3 is provided at the lower part of both side edge of the crosspiece 14, and the girder 22 of the wheel unit 2 described later is fitted to the long lower edge. A fitting recess 14c for inserting is provided.

The crosspiece 15 is formed by connecting an insertion plate 17 having a large vertical dimension and an insertion plate 18 having a small vertical dimension so as to sandwich the top plate 16, and at a long end edge of the insertion plates 17 and 18 away from the top plate 16. , Five cut grooves 17a and 18a for meshing with the crosspiece 14 are inserted, respectively. Further, an engaging projection 17b for fixing to the tray 3 is provided at the lower part of both side edge of the insertion plate 17.

Here, the engaging protrusions 14b and 17b of the crosspieces 14 and 15 have outer edges so as to be tapered for smooth fitting of the fixing member 4 to the tray 3 and fixing in that state, as will be described later. The lower part of the tray is formed diagonally, and the upper edge is horizontal.

To assemble the tray 3 from the blank as described above, as shown in FIG. 3, the outer plate 8 is bent upward from the bottom wall 5, the opposing bent pieces 12 are bent inward, and the tray 3 is engaged with the engaging projection 12a. The upright state of the outer plate 8 is maintained by engaging the joint notch 12b.

Next, the outer plate 10 is bent upward from the bottom wall 5, the bent piece 13 is bent in the valley fold direction from the inner plate 11, and the inner plate 11 is bent downward from the outer plate 10 to form the outer plate 10 and the inner plate. A side wall 7 having a polymerized structure in which a bent piece 12 is sandwiched between 11 is formed.

Further, the bent piece 13 is placed along the inside of the outer plate 8, the inner plate 9 is bent downward from the outer plate 8, and the bent piece 13 is sandwiched between the outer plate 8 and the inner plate 9. The side wall 6 is formed. In this state, the protrusions on both side edges of the inner plate 9 are pressed against both sides of the surface of the inner plate 11, restoration due to repulsion of the inner plates 9 and 11 is suppressed, and the tray 3 is held in the assembled state.

On the other hand, the fixing member 4 is arranged in a direction orthogonal to the cut grooves 17a and 18a of the two crosspieces 15 in which the insertion plates 17 and 18 are bent downward from the top plate 16 of the crosspiece 15 and arranged in parallel. By engaging the cut grooves 14a of the five crosspieces 14, the crosspieces 14 and 15 are formed into a grid shape in which the crosspieces 14 and 15 are combined vertically and horizontally.

When using the tray carriage composed of the above members, the pair of wheel units 2 are inserted into the tray 3 from above, and the wheels 21 are projected downward from the wheel insertion port 5a of the bottom wall 5 of the tray 3. , The base plate 23 is fitted into the wheel insertion port 5a, and the girder member 22 is brought into contact with the upper surface of the bottom wall 5 of the tray 3.

Next, the fixing member 4 is fitted into the tray 3 from above. At this time, since the lower part of the outer edge of the engaging protrusions 14b and 17b of the crosspieces 14 and 15 is cut diagonally so as to be tapered, the inner plates 11 and 9 are pushed outward and oscillated. It descends smoothly.

After that, as shown in FIGS. 1 and 2, when the engaging protrusions 14b and 17b pass through the lower ends of the inner plates 11 and 9, the inner plates 11 and 9 are elastically restored and the engaging protrusions 14b and 17b are restored. The upper end edge of the wheel unit 2 is engaged with the lower end edges of the inner plates 11 and 9, respectively, and the girder member 22 is fitted into the fitting recess 14c, and the fixing member 4 holds the girder member 22 of the wheel unit 2 from above.

An integrated tray trolley is assembled. In this assembled state, the upper surface of the fixing member 4 is lower than the tops of the side walls 6 and 7 of the tray 3.

When delivering a product G such as a bag of food to a store using such a tray trolley, for example, as shown in FIG. 5, the product G is stored in a cardboard box 19 opened in advance. A large number of corrugated cardboard boxes 19 are stacked on the fixing member 4 of the tray body 1 and covered with a corrugated cardboard cover 20 so as to cover all the corrugated cardboard boxes 19.

In this packed state, the lower portion of the lowermost corrugated cardboard box 19 is fitted into the tray 3 to suppress deviation from the tray 3, but the load of the stacked corrugated cardboard boxes 19 is transferred to the wheel unit via the fixing member 4. It is received by 2 and does not act on the tray 3.

Then, when the product G delivered in such a packed state is displayed at the store, the tray trolley is pushed and moved to the sales floor as the wheels 21 roll, the cover 20 is removed, and as shown in FIG. The product G housed in the cardboard box 19 of each stage is exposed. In addition, the stopper of the wheel 21 is applied to prevent the tray carriage from moving unexpectedly.

As described above, in this tray trolley, a cardboard box 19 containing the product G in a pre-opened state is placed on the fixing member 4 of the tray body 1 without using a basket trolley, and the cover 20 is put on the tray body 1 to go to the store. The product G can be displayed efficiently and labor can be saved simply by delivering the product, pushing it to the sales floor, moving it, and removing the cover 20.

In addition, the tray 3 corresponding to the size of the product G can be used, the transportation efficiency of the product G can be improved, and the handling when moving in the store becomes easy. The wheel unit 2 can be shared with trays 3 having different sizes as long as there is a certain degree of dimensional difference.

Further, since the wheel unit 2 is inserted into the tray 3 and suppressed by the fixing member 4, the corrugated cardboard box 19 containing the product G is placed on the fixing member 4 and moved, so that the tray body 1 and the wheel unit 2 are completely integrated. , The wheel unit 2 does not suddenly come off from the tray body 1 during movement.

Further, after the display is completed, the tray body 1 can be disassembled, the tray body 1 and the wheel unit 2 can be separated, and the tray body 1 made of corrugated cardboard can be recycled without being stored, so that it is necessary to store the car. In addition to reducing the space required for distribution such as a backyard, the wheel unit 2 is not bulky even when stored and can be used repeatedly.

In the above embodiment, the crosspiece 14 and the insertion plate 17 of the crosspiece 15 are provided with engaging projections 14b and 17b that engage with the tray 3, respectively, but the engaging projections 14b of the crosspieces 14 and 15 are provided. , 17b may be omitted.

Further, in the tray body 1, the product G is placed on the fixing member 4 in a state of being housed in the cardboard box 19, but depending on the size and properties of the product G, the product G is fixed without being housed in the cardboard box 19. It may be placed directly on the member 4.

Further, although the tray 3 has an open top surface as an example, the tray 3 may be a box body having a lid on the top surface.

In addition, as the tray 3, an assembly type in which a pair of side walls 6 and 7 are continuously provided around the bottom wall 5 is illustrated, but the tray 3 is a tray 3 of each pair of side walls 6 and 7 connected in the circumferential direction. A so-called semi-A type may be used in which a flap forming the bottom wall 5 is extended from the lower end.
