Both side edges of the wheel insertion opening 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 cardboard from being broken.

  The fixing member 4 includes 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. Five blanks are used, and two blanks of the crosspiece 15 are used.

  The crosspiece 14 has a long plate shape, and two sets of long and short cut grooves 14a for engagement with the crosspiece 15 are provided at the upper end edge above the crosspiece 14. Further, engaging projections 14b for fixing to the tray 3 are provided at the lower portions of both side edges of the crosspiece 14, and a beam member 22 of the wheel unit 2 described later is fitted to the lower long edge. A fitting recess 14c is provided.

  The crosspiece 15 is formed by connecting a large insertion plate 17 and a small insertion plate 18 with a top plate 16 sandwiched between them, and a long edge of the insertion plates 17, 18 away from the top plate 16. Each of the cut grooves 17a and 18a for meshing with the crosspieces 14 is provided. In addition, engaging protrusions 17 b for fixing to the tray 3 are provided at lower portions of both side edges of the insertion plate 17.

  Here, the engaging projections 14b and 17b of the crosspieces 14 and 15 have outer edges that are tapered so that the fixing member 4 can be smoothly fitted into the tray 3 and fixed in that state, as will be described later. The lower part is formed diagonally and the upper edge is horizontal.

  In order 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 and the opposed bent pieces 12 are bent inward to engage with the engaging protrusions 12a. The standing state of the outer side plate 8 is maintained by engaging the joint cuts 12b.

  Next, the outer side plate 10 is bent upward from the bottom wall 5, the inner plate 11 is bent downward from the outer side plate 10, while the bent piece 13 is bent from the inner side plate 11 in the valley folding direction. A side wall 7 of a superposed structure in which a bent piece 12 is sandwiched between 11 is formed.

  Further, the bent piece 13 is placed along the inner side 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. Sidewall 6 is formed. In this state, the protruding portions on both side edges of the inner plate 9 are in pressure contact with both side portions of the inner plate 11, so that restoration due to repulsion of the inner plates 9, 11 is suppressed, and the tray 3 is held in the assembled state.

  On the other hand, the fixing member 4 is formed by bending the insertion plates 17 and 18 downward from the top plate 16 of the crosspiece 15 and arranging the cut grooves 17a and 18a of the two crosspieces 15 in parallel and in a direction perpendicular thereto. By engaging the cut grooves 14a of the five crosspieces 14, the crosspieces 14 and 15 are formed in a cross beam shape that is combined vertically and horizontally.

  And when using the tray cart which consists of said each member, while inserting a pair of wheel unit 2 into the tray 3 from upper direction, and making the wheel 21 protrude below 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 opening 5 a, and the girder 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, the engaging projections 14b and 17b of the crosspieces 14 and 15 are tapered so that the lower part of the outer edge is cut so as to be tapered, so that the inner plates 11 and 9 are pushed outward to swing. Descent smoothly.

  Thereafter, as shown in FIGS. 1 and 2, when the engaging projections 14b and 17b pass through the lower ends of the inner plates 11 and 9, the inner plates 11 and 9 are restored by elasticity, and the engaging projections 14b and 17b are restored. Are engaged with the lower edges of the inner plates 11 and 9, respectively, and the girder 22 is fitted into the fitting recess 14c, so that the fixing member 4 holds the girder 22 of the wheel unit 2 from above. Become.

  Thereby, even if the wheel 21 is grounded to the floor surface and the girder 22 tries to push up the fixing member 4 against the tray 3, the fixing member 4 does not rise, and the tray body 1 and the wheel unit 2 are completely separated. An integrated tray cart 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.

  For example, as shown in FIG. 5, when a product G such as a packaged food is delivered to a store using such a tray cart, the product G is accommodated in a cardboard box 19 opened in advance. Then, a large number of cardboard boxes 19 are stacked on the fixing member 4 of the tray body 1 and a cardboard cover 20 is covered so as to cover all the cardboard boxes 19.

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

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

  As described above, in this tray cart, without using a car, the cardboard box 19 containing the product G in an open state is placed on the fixing member 4 of the tray body 1 and the cover 20 is put over to the store. The product G can be displayed efficiently by simply delivering it, pushing it to the sales floor, moving it, and removing the cover 20, thereby saving labor.

  Further, the tray 3 corresponding to the size of the product G can be used, the transportation efficiency of the product G can be increased, and handling during the movement in the store is facilitated. The wheel unit 2 can be shared with the trays 3 having different sizes as long as they have a certain dimensional difference.

  Further, since the wheel unit 2 is inserted into the tray 3 and restrained by the fixing member 4, and the cardboard box 19 containing the product G is placed on the fixing member 4 and moved, the tray body 1 and the wheel unit 2 are completely integrated. The wheel unit 2 is not unexpectedly detached from the tray body 1 during the 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 can be recycled without storing the cardboard tray body 1, so the car must be stored. In addition to reducing the space required for logistics such as a backyard, the wheel unit 2 does not become bulky even when stored and can be used repeatedly.

  In the above-described embodiment, the engagement projections 14b and 17b that engage with the tray 3 are provided on the insertion plate 17 of the crosspiece 14 and the crosspiece 15, respectively. However, the engagement projection 14b of the crosspieces 14 and 15 is provided. , 17b may be omitted.

  In the tray body 1, the product G is placed on the fixing member 4 in a state of being accommodated in the cardboard box 19. Depending on the size and property of the product G, the product G may be fixed without being accommodated in the cardboard box 19. You may make it mount directly on the member 4. FIG.

  Further, although the tray 3 is illustrated with the top surface opened, the tray 3 may be a box having a lid on the top surface.

  In addition, as an example of 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 includes a pair of side walls 6 and 7 connected in the circumferential direction. It is good also as what is called a semi-A type from which the flap which forms the bottom wall 5 was extended from the lower end.
