DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing structure for an assembling type rearranging case comprising a frame and a drawer molded from a synthetic resin material, and a flat reinforcing plate is provided between vertical frames. This is to prevent the top plate and the like from bending when a load is applied to the top plate and the like.

[0002]

2. Description of the Related Art Conventionally, an assembling type rearranging case is generally constructed such that an arbitrary number of unit frame members having drawer insertable / removable shapes are fitted to each other and stacked, and a top plate is covered and a top plate is provided at the top. The lower four corners have a structure to which a moving caster is attached if necessary, and the drawer shape is long in the width direction and long in the depth direction.

[0003] The unit frame is, for example, a horizontal frame formed by forming an inverted U-shaped frame having a cross-sectional shape opening downward into a rectangular shape, and a vertical frame having fitting projections at upper ends at four corners thereof. The drawer is slidable on the upper surface of the horizontal frame by integrally mounting or fitting the frame, and fitting recesses are formed at four corners of the rear surface of the horizontal frame so that the fitting projections of the lower unit frame body can be fitted therein. Configuration.

The top plate has a flat upper surface on which various articles can be placed. At the four corners of the back surface, similarly to the back surface of the unit frame, a fitting protrusion at the upper end of the vertical frame of the unit frame is provided. A fitting recess having a shape in which the portion can be fitted is provided.

[0005] In a general assembly type rearranging case having such a basic structure, the top plate is supported only by vertical frames fitted to the four corners. When the top plate is not sufficiently supported in any of the longitudinal directions in the depth direction, and a heavy object is placed on the top surface of the top plate, the top plate is deformed by the heavy pressure and bent downward, and the drawer is inserted. There was a case where it was obstructed for removal and opening and closing.

For this reason, as disclosed in, for example, Japanese Utility Model Publication No. 6-4742, a pipe-like reinforcing member is internally fitted into a frame fitted into the opening of the box body to reinforce the frame. Something like that has been proposed.

[0007] For example, utility model registration No. 301092
No. 3 and No. 301554 propose a rearranging case in which a reinforcing rod having a pipe-like or rectangular cross-section (inverted U-shape) is hung between support members to prevent deformation of a top plate.

[0008]

However, each of the above reinforcing means is formed by bending a pipe-shaped reinforcing member so as to fit into a frame of an opening, or by bending a metal plate into an inverted U-shaped cross section. Since the bending process is required, the reinforcing member itself is expensive, the processing cost is large, and the locking structure of the reinforcing member is relatively complicated.

Further, since each of the above reinforcing members has no support at all in its long central portion due to its structure, when a load is continuously applied to the top plate (a) for a long period of time, the reinforcing members are not supported. (B) The shape itself is gradually deformed due to aging, and the center portion is bent, which may hinder insertion / removal of the drawer and opening / closing of the drawer. 6 (a), (b)).

SUMMARY OF THE INVENTION It is an object of the present invention to provide a reinforcing structure for an assembling type rearranging case which prevents a top plate or a frame from being deformed by a load and allows a drawer to be inserted and removed and opened and closed reliably. Is what you do.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to an assembling rearranging case comprising a unit frame, a top plate and a drawer. A vertically elongated mounting groove is provided, and a reinforcing plate made of a rigid plate having a predetermined width is vertically installed between the mounting grooves facing each other. Is what you do.

That is, the reinforcing plate is installed between the desired vertical frames to receive the load applied to the top plate or the like and prevent the top plate or the like from being deformed. By using the rigid reinforcing plate, the deformation of the reinforcing plate itself against a load in the vertical direction is prevented, so that the deformation is not caused for a long period of time.

[0013] Further, in particular, the above-mentioned reinforcing plate is provided on the upper side of the drawer opening to prevent the deformation, so that the drawer can be inserted and removed and opened and closed reliably.

Further, by means of vertically hanging guide ribs for holding the reinforcing plate between the opposed fitting recesses provided on the back surfaces of the unit frame and the top plate, the reinforcing plate is twisted and deformed in the lateral direction. This is to prevent it.

Alternatively, instead of the guide ribs, the reinforcing plate is twisted by means of providing a holding piece for sandwiching the reinforcing plate at at least one position between the fitting recesses facing each other provided on the back surface of the unit frame and the top plate. This prevents deformation due to

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a reinforcing structure of a prefabricated rearranging case according to the present invention. 1 and 2, reference numeral 1 denotes a unit frame of a rearranging case, 2 denotes a drawer that can be inserted into and removed from the unit frame 1, and 3 denotes a top plate that covers the upper end of the unit frame 1 installed on the uppermost stage. However, all of them are integrally molded from a suitable synthetic resin material. Here, the unit frame is the basis of the frame structure in this kind of assembling type rearranging case, and when assembling into a desired number of steps as described below, each unit is constituted by this unit frame. It shall be standardized so that it can be performed.

Reference numeral 8 denotes a reinforcing plate, for example, as described below, for example, two vertical frames 5, 5 located at the front of the rearranging case.
Although it is provided between them, it is made of a thin plate having a predetermined width at least in the vertical direction, and is made of a rigid plate made of a rigid metal or a synthetic resin.

The unit frame 1 has a rectangular U-shaped frame whose cross section is open downward and has a rectangular shape, and the upper surface thereof is a horizontal frame 4 on which the drawer 2 can slide. Vertical frames 5, 5 provided with fitting projections 6 at the upper ends at the four corners
Each of the horizontal frames 4 is provided with fitting recesses 7, 7... At the four corners on the rear surface of the horizontal frame 4 corresponding to the vertical frame 5 so that the fitting projections 6 of the lower unit frame 1 can be fitted. Each is provided.

The drawer 2 is composed of a box 2a having an open upper surface slidable on the horizontal frame 4 of the unit frame 1, and a handle 2c of an appropriate shape is provided on the front plate 2b. Further, the top plate 3 has a flat upper surface on which various articles can be placed, and the upper end of each of the uppermost vertical frames 5 is fitted to the four corners of the rear surface similarly to the rear surface of the horizontal frame 4 of the unit frame 1. Mating part 6
Are provided, each of which has a fitting recess 7, 7,...

A caster or the like (not shown) is attached to the rear surface of the lowermost unit frame 1 so as to be movable.

The above-described structure is a basic structure which is almost common to this type of conventional sort box except for the reinforcing plate 8, and a required number of unit frames 1 are fitted to the mating convex portions. 6 and fitting recesses 7 are fitted together and stacked, the top plate 3 is similarly fitted and covered on the uppermost stage, and the drawer 2 is inserted into each stage to complete the arrangement case.

Next, in the fitting projections 6 of the vertical frames 5, 5 provided in parallel with the front surface of the case, ie, the drawer opening, 9 is a mounting groove in which the reinforcing plate 8 is fitted. The mounting projections 6 are provided vertically vertically at positions facing each other. The length of the mounting grooves 9 in the vertical direction is the same as the height of the reinforcing plate 8 in the vertical direction. The width of the reinforcing plate 8 is substantially equal to the thickness of the reinforcing plate 8, and the width is slightly widened toward the upper end so that the reinforcing plate 8 can be easily inserted. Reference numeral 10 denotes a connecting projection that fits into a connecting hole provided in the fitting recess 7 on the back surface of the top plate 3 described below.

On the other hand, in the fitting concave portion 7 on the back surface of the top plate 3, a fitting notch 11 is provided at a position corresponding to the mounting groove 9 on the side wall of the concave portion, and the connecting protrusion 1 of the fitting convex portion 6 is provided.
Then, a connection hole 12 that engages with each other is formed. The upper end portion of the fitting notch 11 is also approximately equal in width to the thickness of the reinforcing plate 8 and slightly wider downward (see FIG. 2). Thus, at the time of fitting, the reinforcing plate 8 is securely held by the mounting groove 9 and the fitting notch 11.

Further, reference numeral 13 denotes a guide rib of the reinforcing plate 8, which is vertically suspended in parallel between the fitting notches 11 on the back surface of the top plate to clamp the reinforcing plate 8 and to reinforce the oblique force. This prevents the plate 8 from being twisted and deformed (see FIG. 5).

Therefore, as long as the purpose of preventing the deformation can be achieved, it is not necessary to provide a rib over the entire length thereof. For example, as shown in FIG. A pair of holding pieces 13a protruding so as to sandwich the reinforcing plate 8 may be provided at the central portion.
The number can be appropriately selected according to the distance between the two. In the case where the ribs are provided over the entire length as in this example, even if the reinforcing plate 8 is not attached to the portion, the ribs perform the same function as the conventional reinforcing ribs. is there.

When assembling the rearranging case, especially for the parts requiring reinforcement, the reinforcing plate 8 is used.
Is installed between the vertical frames 5 using the mounting grooves 9 and the top plate 3 is covered from above, thereby deforming the top plate 3 against a load from above as shown in FIG. Can be reliably prevented. Also, at this time, since the reinforcing plate is formed of a flat plate unlike a conventional pipe-shaped member or the like,
Even if the load is applied for a long period of time, there is no fear of deformation due to aging.

In the above embodiment, the prevention of the deformation of the front surface of the top plate 3, ie, the upper side of the drawer opening, has been described. Since the mounting groove 9 and the like are provided also in this embodiment, this reinforcing structure is applied to the fitting portion, preventing deformation of the horizontal frame below the middle stage and eliminating obstacles in insertion / removal and opening / closing of the lower drawer. Obviously, by providing the mounting grooves 9 so as to face each other in the depth direction, the side surfaces can be similarly reinforced.

The reinforcing plate 8 has a fitting height between the fitting projection 6 and the fitting recess 7 at a fitting portion between the top plate 3 and the unit frame 1 or between the upper and lower unit frames 1. Since it is installed and installed using the above, it is completely contained inside the back surface of the top plate 3 or the horizontal frame 4 and cannot be seen from the outside at all,
It does not detract from the beauty of the organizing case.

[0029]

As described above, the reinforcing structure of the assembling type rearranging case according to the present invention is such that a flat reinforcing plate is vertically erected and mounted between a top plate and a unit frame. Therefore, even if a large load is applied to the top plate or the like, there is no possibility that the top plate and the unit frame are deformed, and the drawer can be inserted and removed and opened and closed very smoothly. In addition, the above-mentioned deformation can be prevented for a long period of time particularly by adopting a flat shape.

Further, the structure of the mounting portion of the reinforcing plate is simple,
Since it can be mounted simply by inserting a reinforcing plate made of a flat plate from above, any frame can be reinforced very easily and the manufacturing cost can be provided at low cost.
