JPS5810519Y2 - Box bottom plate mounting structure - Google Patents

Description

[Detailed explanation of the idea] This invention relates to a structure for attaching a bottom plate to a box body.

When attaching a bottom plate to a metal box with an open bottom, stack the seat plates on the four corners of the bottom plate and tighten the two setscrews on each side.
The bottom plate is usually screwed to the bottom of the main body.

In other words, bend the bottom of the main body inward at right angles, drill two screw holes in each of the four corners of the piece, and drill two holes in positions corresponding to the bottom plate to be attached, for a total of eight holes. Seat plates with two through-holes were placed one on top of the other at the four corners, and the seat plates and bottom plate were fixed with eight screws, two each.

In order to secure the seat plates at the four corners, two screws were required for each seat plate.

Of course, in some cases three or more screws were used to attach the seat plate to each corner.

Such a mounting structure has the advantage that the shape of the seat plate is simple and that the mounting work can be performed without regard to the direction.

However, there are many screws to be screwed, making the work complicated, and furthermore, the bottom plate cannot be temporarily secured unless at least two screws are screwed in, resulting in poor workability.

The present invention makes it possible to easily and quickly attach the bottom plate by using a seat plate having a protruding piece, by easily and temporarily fixing the bottom plate, and by reducing the number of places where screws need to be fixed.

Hereinafter, the structure, operation, and effects of the present invention will be explained in detail with reference to drawings showing embodiments.

FIG. 1 is a perspective view showing an example of a rice bin set.

The rice bin set 1 is a rectangular parallelepiped box with a top plate 2 on the top, side plates 3 on both sides, a bottom plate 4 on the bottom, and a back plate 5 on the back.
has.

When viewed from the front, it includes a storage part 6, an unloaded lower part, and a rice bin part 8 in this order from the top.

The mounting structure of this bottom plate is the object of the present invention, and FIG. 2 is an exploded perspective view of the vicinity of the bottom showing the procedure for mounting the bottom plate.

FIG. 3 is a partial sectional view of the bottom plate attachment part.

The main body is made of metal plate and has an opening at the bottom.

The lower ends of the side plates 3, 3, back plate 5, and front plate 5' of the main body are bent inward at right angles to narrow bent pieces 9, 9 on the bottom of the main body.・
It is...

Body bottom bent piece 9, 9. . . . are four sides, and the corners are in contact with each other along the bisector m forming an angle of 45°.

In order to attach the bottom plate 4 to the main body, seat plates 10 are used at the four corners.

Two insertion holes 11, 11 are bored in each of the four corners of the bottom plate 4, and bottom piece retaining holes 12, 12, . ..., the top and bottom match.

The bottom piece retaining holes 12.12 are arranged on both sides of the bisector m.

The seat plate 10 is made of hard rubber, hard plastic, aluminum, etc., and includes a vertical protruding piece 13 and a through hole 14.

The protrusion piece 13 and the through hole 14 are located at the insertion hole 1 of the bottom plate 4.
1,11. It coincides with the stopper hole 12.12 of the bent piece 9 on the bottom of the main body.

Next, the installation procedure will be explained.

The opening of the main body is covered with the bottom plate 4, the insertion hole 11 of the bottom plate is aligned with the bottom piece fixing hole 12, and the protruding piece 13 of the seat plate 10 is closed.
into the insertion hole 11 and the bottom piece fixing hole 12.

The seat plate 10 is inserted into two or more bottom plate insertion holes 11. When inserted into the fixing hole 12, the bottom plate is temporarily fixed.

The bottom plate no longer slides on the bottom of the main unit.

Therefore, all four seat plates 10 are inserted into the insertion holes 11. The protruding piece 13 is pushed into the stopper hole 12 and fixed.

Next, the set screw 15 is inserted from the through hole 14 into the bottom piece retaining hole 12 through the insertion hole 11 of the bottom plate, and is screwed into the inner retaining hole 12.

An ordinary countersunk screw may be used as the set screw, and is screwed in so that the head is slightly recessed from the surface of the seat plate 10, as shown in FIG.

This is to prevent the screw head from damaging the floor surface.

FIG. 4 is a top perspective view of the seat plate 10.

The seat plate is an oval-shaped plate, and a protruding piece 13 is provided on the right side and a through hole 14 is provided on the left side when viewed from the inner upper surface.

The abbreviated shape is the corner of the bent piece 9 on the bottom of the main body.

It does not have to be L-shaped, and may be square.

A shape close to an isosceles right triangle may also be used.

The position of the protruding piece may be either left or right.

Further, a tapered protruding piece may be used, or if the seat plate has a plurality of protruding pieces and a plurality of protruding pieces are inserted, the bottom plate can be temporarily fixed with one seat plate.

The effects of the present invention will be described below.

Compared to the conventional mounting structure in which each seat plate is fixed with two screws, the work required for screwing is reduced by half.

Turning screws using a screwdriver is time-consuming and tedious, but cutting this effort in half has a great effect.

Furthermore, the protruding piece 13 is inserted into the insertion hole 11 of the bottom plate 4. Since the bottom plate is temporarily fixed by simply inserting it into the bottom piece fixing hole 12, there is no need to hold the bottom plate with one hand when tightening the screws.

Screw tightening work becomes easier. In addition, although there is only one screw for fixing each seat plate, the protruding piece 13 is attached to the bottom plate insertion hole 11.
．． Since it passes through the bottom plate fixing hole 12, the seat plate will not rotate relative to the bottom plate even if the main body is shifted relative to the floor.

Therefore, the seat plate should be installed as far outward as possible, for example,
It is installed flush with the side wall surface of the bottom of the main unit, improving the stability of the main unit.

In other words, when the seat plate rotates, the seat plate protrudes outward from the side wall surface of the bottom of the main body, reducing the pressure-receiving effect and becoming a nuisance when used side by side with culture items.

The seat plate and bottom plate do not come off even if the main body is lifted, as they are not simply stopped by the action of the protruding piece, but are screwed.

Furthermore, the mounting structure for the bottom plate of a rice bin set is illustrated as an example, but it is not limited to a rice bin, but can be used for any box body, such as a food storage box.
Can be used to attach the bottom plate of lockers, bookshelves, etc.
It has a wide range of uses.

In this way, the present invention is a useful invention.
