A mobile storage box according to an embodiment will be described with reference to FIGS. 1 to 7. FIG. 1 and the left side of FIG. 5 are defined as the front side (front side) of the movable storage box, and the description will be made on the basis of the vertical and horizontal directions when viewed from the front side.

As shown in FIG. 1, the mobile storage box 1 is provided at the lowest part of a product display fixture 10 used, for example, in supermarkets, convenience stores, etc., and is located between a base 11 forming a downward U-shape and the floor. It is stored in the lower space and used by taking it in and out as needed.

As shown in FIGS. 2 and 3, the mobile storage box 1 has a box-like shape with an open top, and has casters 7, 7, and 4 fixed to a steel plate housing 2 capable of storing articles. It is supported on the floor by 7, 7 (caster device), making it easy to move in and out of the base 11. As shown in FIG. The housing 2 is mainly composed of a pair of left and right side plates 4 , 4 (standing plates), a bottom plate 6 , a front plate 3 and a rear plate 5 .

The front plate 3 is provided with a handle 31 formed at its upper end by bending to form a substantially inverted L shape when viewed from the side (see FIGS. 2, 3, 4 and 5).

The side plate 4 has a main side surface portion 40 extending in the vertical direction, a flange piece 41 extending left and right from the lower end of the main side surface portion 40 , and a locking piece 42 extending downward from the flange piece 41 . Four rivet holes 44, 44, 44, 44 are formed in the flange piece 41, and as shown in the enlarged view of FIG. A rectangular non-return claw 43 (positioning means) is pushed downward, protrudes rearward, and has a substantially L shape when viewed from the side. The flange piece 41 and the locking piece 42 are formed by bending.

The rear plate 5 is integrated with the pair of side plates 4, 4, and the rear plate 5 and the pair of side plates 4, 4 are formed by bending a single steel plate (see FIG. 3).

The bottom plate 6 has a main bottom portion 60 extending horizontally, vertical pieces 61 extending upward from the left and right ends of the bottom plate 6, and horizontal pieces extending left and right outward from the vertical pieces 61 and having approximately the same size as the flange pieces 41 of the side plate 4. 62 and . Further, the horizontal piece 62 is formed with four rivet holes 64, 64, 64, 64 and an engaging hole 63 (positioning means).

At the rear end of the bottom plate 6, an upwardly extending back restraining piece 65 is provided. A back step portion 66 is provided. The vertical piece 61, the horizontal piece 62, the back regulation piece 65, and the back step portion 66 of the bottom plate 6 are formed by bending.

The caster 7 includes a wheel 71 in contact with the floor, a substantially rectangular fixed piece 73 in contact with the housing 2, a support 72 disposed between the wheel 71 and the fixed piece 73, and the support 72. and an axle 75 connecting the wheels 71. The fixing piece 73 is formed with two rivet holes 74, 74 which are separated from each other by a predetermined distance in the front-rear direction. Since the four casters 7, 7, 7, 7 have substantially the same structure, only the structure of one caster 7 will be described below unless otherwise specified.

A procedure for assembling the mobile storage box 1 will be described. As shown in FIGS. 6 and 7, the non-return claw 43 of the flange piece 41 of the side plate 4 is inserted into the engagement hole 63 of the horizontal piece 62 of the bottom plate 6 located below, and is slid from the front to the rear. The flange piece 41 and the horizontal piece 62 are temporarily fixed to form an overlapped portion 9 in which the flange piece 41 and the horizontal piece 62 are in contact with each other vertically (see FIG. 8). When the non-return claw 43 is engaged and fixed to the engaging hole 63, the integrated side plate 4 and rear plate 5 are moved rearward relative to the bottom plate 6, and the back restricting piece 65 of the bottom plate 6 is moved. The front surface of the rear plate 5 contacts the rear surface of the lower end of the rear plate 5 so that the front and rear positions are regulated at a predetermined position, and the front and rear positions of the rivet holes 44, 64, 74 are aligned.

Next, from the state shown in FIG. 8, the fixed piece 73 of the caster 7 is brought into contact with the lower surface of the overlapped portion 9 (horizontal piece 62), and the rivet holes 44, 44, the rivet holes 64, 64, and the rivet holes 74, 74 are pressed. The fixing piece 73 is fixed to the overlapping portion 9 by inserting the rivets 8, 8 from above and crimping them (see FIG. 7).

The front plate 3 is fixed to the side plates 4, 4 and the bottom plate 6 with screws (not shown). It should be noted that fixing by means of locking means or welding may be used instead of fixing by screws. Also, the front plate 3 may be fixed to the side plates 4, 4 or the bottom plate 6. FIG.

As explained above, the casters 7 are fixed below the overlapping portion 9 . According to this, since the overlapped portion 9 is configured by vertically overlapping the flange piece 41 of the side plate 4 and the horizontal piece 62 of the bottom plate 6, the overlapped portion 9 can be used as a pedestal for the caster 7 with high strength. In addition to being usable, since the casters 7 are fixed to the overlapping portion 9, the number of parts can be reduced and assembly is facilitated.

Further, since the casters 7 are fixed together with the overlapped portion 9 by the same rivets 8, the number of members can be reduced and assembly is facilitated.

In addition, in the overlapping portion 9, the flange piece 41 of the side plate 4 and the horizontal piece 62 of the bottom plate 6 overlap each other vertically. According to this, since the outer ends of the bottom plate 6 in the left-right direction are stepped, the strength of the bottom plate 6 is increased. When the housing 2 is supported by the casters 7, 7, 7, 7, since the bottom plate 6 is closer to the floor surface than the horizontal piece 62, the storage space of the housing 2 is wide in the vertical direction.

In addition, since the side plate 4 is provided with locking pieces 42 extending downward at the left and right ends of the flange pieces 41, positioning in the left-right direction with respect to the horizontal pieces 62 of the bottom plate 6 is facilitated.

In addition, by engaging and fixing the non-return claws 43 of the flange piece 41 of the side plate 4 with the engaging hole 63 of the horizontal piece 62 of the bottom plate 6 arranged below, the flange piece 41 of the side plate 4 and the bottom plate 6 are fixed. , and the horizontal piece 62 can be placed in a superimposed state, so that the fixing means can be easily fixed.

Also, the bottom plate 6 is provided with a spine regulating piece 65 extending upward at its rear end. According to this, when the non-return claw 43 of the flange piece 41 of the side plate 4 is fixed to the engaging hole 63 of the horizontal piece 62 of the bottom plate 6, the front surface of the back restraining piece 65 is positioned at the lower end of the rear plate 5. Since it abuts on the rear surface and overlaps on the front and back, the strength of the contact portion can be increased and the number of parts can be reduced.

In addition, the rear plate 5 is integrated with the pair of side plates 4, 4 and is formed by bending a single steel plate, so that the number of parts can be reduced while maintaining strength.

Further, the handle 31 of the front plate 3, the flange piece 41 and locking piece 42 of the side plate 4, and the vertical piece 61, horizontal piece 62, back regulation piece 65 and back step portion 66 of the bottom plate 6 are bent. The number of parts can be reduced while maintaining strength.

Further, the front plate 3 extends left and right so as to cover the locking pieces 42, 42 of the pair of side plates 4, 4 when viewed from the front. According to this, the left and right rivets 8, 8, the overlapping portions 9, 9, and the locking pieces 42, 42 can be reliably hidden from the front view by the front plate 3, and the appearance is excellent (see FIG. 4). ).

A modification of the embodiment will be described. It should be noted that the same reference numerals are given to the same components as those shown in the above embodiment, and redundant explanations will be omitted. As shown in FIG. 9 as Modified Example 1, the overlapping portion 9 is fixed by a rivet 8a, and the caster 7 is fixed to the lower surface of the horizontal piece 62 by spot welding 81a. Thus, the caster 7 may be fixed to the overlapped portion 9 by another fixing means.

As a modification 2 shown in FIG. 10, in the side plate 4b, the flange 41b may extend inward in the left-right direction from the lower end of the main side surface portion 40b. According to this, since the caster 7 is arranged inside the housing 2 in the left-right direction, it fits well in the left-right direction. Further, as shown in FIG. 11 as a modification 3, the left and right ends of the main bottom portion 60c of the bottom plate 6c may not have a stepped shape but may have a horizontal plate shape. According to this, since the main bottom portion 60c of the bottom plate 6c has substantially the same height as the mounting portion of the caster 7, it is possible to prevent the bottom surface of the housing 2 from rubbing against the floor surface, for example, on an uneven floor surface.
