Description

[Detailed explanation of the invention] This invention is based on the first steel plates of rice racks placed above and below.
The present invention relates to an assembly structure of a storage shelf in which a box body and a second box body made of a steel plate such as a storage case are integrally assembled via a shelf plate/partition plate made of synthetic resin, plywood board, etc.

As a conventional assembly structure of this type, for example, the first
As shown in Figure A, the upper end edge of the first box 1 made of steel plate and the lower end edge of the second box 2 made of steel plate are respectively bent inward to form a first attachment part 1a and a second attachment part 2a. A shelf/partition plate 3 made of wood, synthetic resin, etc. is placed on the upper surface of the first box 1, and a second mounting portion of the second box 2 is mounted on the shelf/partition plate 3. 2a is positioned on the step 3a formed on the shelf/partition plate 3, and the screw 4 is inserted into the through holes 1b, 3b, 2b from below, and then the vertical cross-sectional shape is fitted into the step 3a. In some cases, the nut 5 is screwed onto a U-shaped cover body 6 fixed to the inside, and in another case, the nut 5 is welded to the first attachment part 1a of the first box body 1, as shown in FIG. 1B. Are known.

However, in the case of the first example above, since the nut 5 is in a free state, the screw 4 and the nut 5 must be screwed into both the boxes 1 and 2 at the same time. It needs to be done and cannot be done easily.

In this regard, in the case of the second example above, the nut 5 is the first
Since the screws 4 are welded to the side of the box body 1, all you have to do is put your hand inside the second box body 2 and operate the screws 4, making the screwing work easy. This causes the following inconveniences. In other words, when manufacturing a box made of steel plates, it is more efficient and mass-producible to bend and form a painted steel plate than to bend and form an unpainted steel plate and then apply paint to it. Although it is well known that welding the nut 5 to the painted box body, that is, the first box body 1, is extremely difficult in terms of welding, and furthermore, the welded area will be significantly discolored, so the second example above is not suitable. A method for welding nuts 5 as shown in FIG.

Furthermore, in both the first and second examples above, since the first and second boxes 1 and 2 and the shelf/partition plate 3 are assembled at the same time, the screws 4 and nuts are assembled simultaneously. Various problems arise when performing the screwing operation with 5. For example, the three parties 1-
3 in a state where the through holes 1b, 2b, and 3b are aligned, it is extremely difficult and troublesome, and furthermore, if the worker accidentally touches the upper second box 2, the second box 2 may be damaged. There is a risk of tipping or falling. Furthermore, since a storage shelf in which both boxes 1 and 2 are assembled together via a shelf/partition plate 3 is quite tall, the three boxes 1 to 3 are usually packaged separately. However, in such cases, the above-mentioned operational problems become more noticeable for users who are not experts. That is clear.

The present invention has been developed in view of the above circumstances, and allows not only experienced but also unskilled persons to assemble the two box bodies and the shelf/partition board extremely easily and easily. To provide an assembly structure of a storage shelf whose body is made of painted steel plate without any problem.

Hereinafter, embodiments of the present invention will be explained in detail with reference to FIGS. 2 to 11.

Further, each vertical plate portion 35 has one side surface that is in close contact with the inner side surface portion 15a of the front pillar portion 15, and the other side surface of each vertical plate portion 35 that does not prevent the rotation of the opening/closing door 24 and the side surface portion 25a of the door body 25 and the guide body 2.
6 (see FIG. 5).

Next, the configuration of the storage case 13 will be explained.

As shown in FIGS. 2 and 10, both front edge portions of the peripheral wall 40 made of a steel plate having a U-shaped cross section are moved inward into a U-shape, leaving opposing upper end portions and portions nearer to both lower ends. The top plate mounting portions 42, 42 are bent to form the front pillar portions 41, 41, and the top plate mounting portions 42, 42 extend in opposite directions along the front surface of the front pillar portion 41, respectively. and shelf plate mounting portions 42', 42'. Note that each mounting portion 42, 42' has the same shape.

Further, the lower end portion of the peripheral wall 40 is bent inward to form a second mounting portion 44, and the lower end portion of the storage case 13 including the second mounting portion 44 and the front pillar portions 41, 41 is Step portion 28 of shelf/partition plate 12
It is designed so that it can be placed in close contact with the

A plurality of long positioning holes 44b, 44b, . . . are formed at positions corresponding to 2, respectively.

A top plate 45 made of a steel plate is attached to the upper surface of the peripheral wall 40. In other words, this top plate 4
5 is configured by bending the peripheral edge portion upward into an L-shape to form a peripheral wall portion 45a and a mounting portion 45b, and the front surface portion of the peripheral wall portion 45a is attached to each of the top plate mounting portions 42, respectively. Tapping screw 46, 46
..., and the mounting portion 45b is formed by bending the upper edge portion of the peripheral wall 40 inward, and is mounted to the mounting portion 47 via tapping screws 48, 48, .

Furthermore, the top plate mounting parts 42, 42 and the top plate 45
A decorative rim 49 made of synthetic resin is attached to the front surface of the frame 49 to cover it. This decorative frame 49
As shown in FIG. 11, a door stop portion 49b is vertically provided on the rear surface of a rectangular columnar portion 49a that is open to the rear, and a filling member that can be fitted between the opposing end surfaces of the top plate mounting portions 42, 42 is provided. A portion 49c is provided protrudingly, and screws 50,
It is attached via 50.

In this installed state, the heads of each of the tapping screws 46 are recessed into the rectangular columnar part 49a, and the lower end of the door stop part 49b is flush with the lower surface of the top plate 45. .

Further, in a portion near the lower end of the peripheral wall 40 and each of the shelf board mounting portions 42', a shelf board 45' made of a steel plate, which is the same as that of the top board 45 inverted vertically, is provided with tapping screws 48, 48, . . . , 46, 46..., and the shelf board 4 thus attached
On the front part of 5', a decorative rim 49' which is the same as the decorative rim 49 upside down is attached to the screws 50, 5.

The mounting condition of the shelf board 45' and the decorative edge body 49' is the same as that of the above-mentioned top plate 45 except that the vertical relationship is reversed. In other words, the top plate 45, the shelf plate 45', and the decorative edges 49 and 49' are common members.

At the ends of the upper and lower decorative edges 49, 49', there is a door 5 made of synthetic resin for opening and closing an opening surrounded by the front pillar parts 41, 41 and the plates 45, 45'.

4 and each screw 34 and each second positioning pin 32
In order to cover the top surface 12a of the shelf/partition plate 12,
This cover body is made of synthetic resin and has a U-shaped vertical cross section and is fitted into the stepped portion 28 surrounded by the peripheral wall 40 and the rear surface of each front pillar portion 41 in a flush state.

The members made of steel plates in the above embodiments are all made by bending painted steel plates.

Next, a method of assembling the rice chest 11 as the first box and the storage case 13 as the second box integrally via the shelf/partition plate 12 will be described with reference to the above embodiment.

First, the shelf/partition plate 12 is positioned and placed on the upper surface of the rice rack 11. This positioning work can be easily performed by inserting each of the first positioning pins 31 of the corresponding shelf/partition plate 12 into each long positioning hole 16b of the first attachment part 16 of the rice rack 11. And it can be done accurately.

Then, each tapping screw 33 serving as a first threaded fixing device is inserted from above into each first through hole 29 of the shelf/partition plate 12, and then screwed into each screwing through hole 16a of the first mounting portion 16. Then, the shelf/partition plate 12 is attached to the upper surface of the rice rack 11 (see FIG. 7). Note that the screwing through hole 16a is such that the tapping screw 33 can be screwed into the screwing through hole 16a sufficiently firmly even without applying a tap finish due to the thin thickness of the first mounting portion 16. Depending on the thickness, a tap finish or the like may be applied.

Next, the storage case 1 is placed on the upper surface 12a of the shelf/partition plate 12 attached to the rice rack 11 in this way.
3 is placed in a positioned state. In this positioning work, the lower end of the storage case 13 is engaged with and placed on the step 28 of the shelf/partition plate 12, and the corresponding second positioning pin 32 of the step 28 is placed on the corresponding second positioning pin 32 of the storage case 13. This can be done simply and accurately by engaging each positioning slot 44b of the second attachment part 44, respectively.

Then, each screw 34 serving as a second threaded fixing device is inserted from above into each insertion hole 44a of the second mounting portion 44, and then inserted into each second through hole 30 of the stepped portion 28 of the shelf/partition plate 12. The storage case 13 is attached to the upper surface part 12a of the shelf/partition plate 12 by screwing it into the nut 43, which is a female screw that has been inserted and fixed in advance.Finally, this attachment part is covered with the cover body 55 (second (See Figures 3 and 8). At this time, first, while holding the storage case 13 with one hand so that it does not fall down, insert your other hand through the opening under the shelf board 45' and tighten the screws 34 at two or three places on the second mounting part 44. By temporarily fixing the storage case 13 with the screws 34, the storage case 13 will not fall down even if you take your hand off it, and the installation work using the screws 34 can be performed safely.

By the way, the rice rack 11, the shelf/partition plate 12, and the storage case 13 constructed as in the embodiment described above have the following structural advantages.

For example, on the front end side of the lower surface portion 12b of the shelf/partition plate 12 which also functions as the top plate of the rice rack 11, there are vertical plate portions 35 and horizontal plate portions 36, 3 each having an abbreviated shape.
Since the rotation regulating member 39 consisting of 7 and 38 is integrally provided vertically, the strength of the shelf/partition plate 12 is improved and deformation when a heavy object is placed thereon can be effectively prevented. That is, the shelf/partition plate 12 made of synthetic resin is made thin due to manufacturing economical requirements, and the peripheral wall 27 is formed in order to avoid as much as possible strength problems and deterioration of the product value in appearance due to the thin wall. However, when attached to the rice rack 11, most of the circumferential wall 27 is received by the first mounting portion 16, but the front side portion of the circumferential wall 27 is located above the upper opening 18 and there is no problem. Since it is not received, the strength of the front end portion of the shelf/partition plate 12 tends to be reduced. However, since the abbreviated rotation regulating member 39 is integrally formed on the front end side of the shelf/partition plate 12 as described above, the above-mentioned inconvenience can be eliminated as much as possible. Furthermore, since the rotation regulating member 39 is made of synthetic resin, the noise generated when the opening/closing door 24 is opened and closed can be reduced.

Moreover, the shape of the rotation regulating member 39 is as follows.
Even though it is made of synthetic resin, the impact caused by the opening and closing of the door 24, that is, the collision between the door body 25 and the second horizontal plate part 37 and the collision between the locking protrusions 26c, 26c and the third horizontal plate part 38 It has a shape that is strong against impact, and the strength of the rotation regulating member 39 itself can also be improved. In addition, when opening and closing the opening/closing door 24, the opening/closing door 24
Both vertical plate parts 35, 35 whose both side parts of 4 are made of synthetic resin
, so that there is almost no rattling in the left-right direction of the opening/closing door 24 , and in connection with this, each protrusion 25 b of the door body 25 is not close to the inner side surface 15 a of each front column 15 . However, since there is no contact, the paint on the inner side surfaces 15a, 15a of both front pillar sections 15, 15 is hardly peeled off due to contact between both side surfaces of the opening/closing door 24 even during long-term use. . This is particularly effective when the door body 25 is also made of steel plate. Furthermore, when the opening/closing door 24 is brought to the open position, the rear side portion 57 (sixth (see figure) is reliably hidden by the side plate portion 35 as shown in FIG. 4B, so that the product value can be increased. Furthermore, due to the structure of the door of the rice rack 11, there is a fairly large gap 58 (see FIG. 4A) between the top plate, that is, the shelf/partition plate 12, and the top surface of the opening/closing door 24.
Since this gap 58 is hidden to some extent by the first horizontal plate portion 36, the product value is increased from this point as well. Furthermore, even when the opening/closing door 24 is brought to the closed position, there is a risk that dust, insects, etc. may enter the rice rack 11 through the large gap 58 described above. Inner side part 15
a and each side surface 25a of the door body 25, and the second horizontal plate portion 37 which is in contact with the rear surface portion of the door body 25 is located between both vertical plate portions 35, Since they are continuous (see Fig. 5), the above-mentioned risk is prevented as much as possible. By the way, garbage etc. are stored in the vertical board section 3.
5, that is, the upper end opening portion 15c (fourth
(see Figure A) into the rice rack 11, but as shown in Figure 9,
This can be prevented to some extent by forming the upper surface of the front column part 15 so as to close it, but in order to make it more reliable, for example, the upper part of each vertical plate part 35 can be marked with a dashed line as shown in FIG. 4A. It is sufficient to extend it to the shaded area. Note that the rotation regulating member 3
9 can be configured such that, for example, the third horizontal plate part 38 is eliminated and the second horizontal plate part 37 also locks the locking protrusions 26c, 26c. 37, and the locking of the opening/closing door 24 in the closed position is restricted by the engagement between the front end edge 35a of each vertical plate part 35 and each protrusion part 25b of the door body 25. You can also do it.

In addition, in the storage case 13, the mounting portions of the top plate 45' and the shelf board 45' to each of the front pillar sections 41 are connected to the mounting portions 4 of which have a horizontal width wider than the horizontal width of each front pillar section 41.
2 and 42' (in the illustrated example, there are 2 locations each)
Since the two plates 45 and 4 are fixed with screws at
The connection strength or connection accuracy (perpendicularity) between 5' and the front pillar portion 41 can be improved. In other words, in the storage case 13, there is a request to make the storage entrance width as large as possible, so the front column part 1 is
It is necessary to set the width of 5 as small as possible,
In this way, each front pillar portion 41 and both plates 4
5, 45' can only be connected with screws at one place due to space, and if the screws are fixed at one place, the connection between the front column part 41 and the horizontal members 45, 45' will be difficult. Sufficient strength or connection accuracy cannot be ensured. In order to satisfy the above requirements, the width of the front pillar portion 41 can be reduced, and the connection strength of the horizontal members 45, 45' can be improved.
Although this is a contradictory requirement to improving the assembly strength of the front column, by integrally forming the mounting portions 42, 42' as described above on the front column portion 41, separate members such as mounting brackets are not required. However, the above conflicting demands can be fully satisfied. It is also possible to weld the horizontal members 45, 45' to the front column part 41, but the need for such a welding method is due to the fact that a painted steel plate is used as the original plate, as mentioned at the beginning. I don't like it because it's difficult.

In addition, the mounting parts 42, 42' and the horizontal members 45, 4
5' and the head of the tapping screw 46 for the connection are covered with the decorative edges 49, 49' and are not exposed to the outside, so the storage case 13 has a good appearance and a high commercial value. Become. Moreover, the horizontal members 45, 45' and the decorative edge body 4
Since 9 and 49' are each a common member, it is more economical to manufacture the storage case 13 than in the case where these parts have different shapes.

As can be easily understood from the above explanation, according to the storage shelf assembly structure of the present invention, it is not necessary to assemble both the boxes and the shelf/partitioner at the same time as in the conventional example mentioned at the beginning. Since the positioning and attachment of the shelf/partition plate to the upper surface of the first box and the positioning and attachment of the second box to the shelf/divider are performed separately, the three separated To easily and accurately assemble a storage shelf without being forced to perform difficult work such as simultaneously positioning and attaching people in a predetermined attachment relationship.

Moreover, the first positioning pin formed on the shelf/partition plate is connected to the first positioning hole of the first mounting part formed on the first box, and the second positioning pin formed on the shelf/partition plate
By simply inserting the positioning pins into the second positioning holes of the second mounting part formed in the second box, the three can be arranged in an accurate mounting positional relationship, and furthermore, this arrangement The above-mentioned installation from above can be done simply by penetrating and screwing the first or second screw-like fixing device from above, so unlike the conventional example mentioned at the beginning, it is not necessary to put your hands into both box bodies at the same time. There is no need for troublesome screwing operations, and even an unskilled person can easily perform the installation work using the screw-like fixtures. In conjunction with this, when attaching the upper second box, hold the second box with one hand while screwing the second screw-like fixture with the other hand. Since the box body can be temporarily fixed, the second box body can be attached safely by preventing the risk of the second box body falling over unexpectedly.

In addition, due to the height of the storage shelves and packaging considerations, there are an increasing number of sales formats in which storage shelves are assembled by the user. Even when separately packaged and sold, the user can easily assemble the three parts as described above, but going one step further, the manufacturer can assemble the first box and the shelf/partition plate. On the user side, only the attachment of the second box to the shelf/partition plate may be performed. This has the advantage that the user can more easily assemble the storage shelf. By the way, in this case, the shelves and partitions are much thinner than each box, so even if the shelves and partitions are attached to the first box, it will not work if the first box is alone. The amount of packaging and packaging time are almost the same, and no inconvenience occurs. In fact, the number of items to be packed is reduced from three to two, which reduces packaging costs.Moreover, when the shelf/partition plate 12 is made of synthetic resin as shown in the above embodiment, the first The box-like rice rack 11 is equipped with an opening/closing door 24 and a shelf/partition board 12.
There is a concern that assembling both 11 and 12 while maintaining proper positional relationship with the rotation regulating member 39 integrally formed with the housing is relatively difficult, especially when the user is a housewife or the like. Such concerns can be reliably eliminated by assembling both 11 and 12 on the manufacturer's side.

Furthermore, since there are no female screws such as nuts welded to each box body for screwing each screw-like fixing device, the coating has various advantages such as no uneven coating and ease of mass production. A steel plate (pre-coated steel plate) can be used as the original plate.

Moreover, even if the first box body and the second box body are screwed using the first and second through holes formed in the shelf board and partition plate according to the present invention, the first and second through holes are Since the holes are formed as thick parts that are thickened inward, it is possible to securely attach both boxes by screwing them together. Moreover, since the thick portions are formed at the locations of the first positioning pin and the first and second through holes, the entire peripheral wall of the shelf/partition plate is set to have a thick dimension, and the first positioning Compared to the case where pins or first and second through holes are formed, the weight of the shelf/partition plate can be significantly reduced, and the material cost can also be significantly reduced. Furthermore, by forming the above-mentioned thick part, this thick part functions as a solid reinforcement part for the peripheral wall of the shelf/partition plate, so the rigidity of the entire shelf/partition plate can be significantly increased. .

Furthermore, since the shelf/partition plate is made of synthetic resin, the elasticity of the material makes it possible to securely fit the female screw into the insertion hole of the second through hole in advance. This has the advantage that there is no need to provide any temporary fixing means.

In addition, the second through hole formed in the thick part of the shelf/partition plate has an upper part as a small diameter hole through which the threaded part of the second threaded fixture can be inserted, and a lower part as a small diameter hole into which the threaded part of the second threaded fixture can be inserted. Since it is a hole, when the threaded part of the second screw-shaped fixture inserted through the small diameter hole is screwed into the female screw that has been inserted and fixed in advance into the insertion hole, the female screw will come out. The lower end surface of the small diameter hole (in other words, the upper end surface of the insertion hole)
is definitely and strongly hit. Therefore, the second box and the shelf/partition plate can be reliably attached between the head of the second screw-like fixture and the female screw, and the attached state can also be firmly established.

In addition, in the present invention, while the first box body and the second box body are made of steel plates, the shelf board/partition plate to which these two box bodies are attached is particularly made of synthetic resin. Since the first and second positioning pins and the first and second through-holes are centrally formed on the shelf/partition plate, these positioning pins and through-holes can be easily molded together with the shelf/partition plate. Not only can the mounting parts of both boxes made of steel plate be drilled, there is no need to form troublesome and complicated mounting parts, and the structure is easy to manufacture as a whole. It is possible to securely attach the body and the shelf board/partition board.

In addition, in the present invention, the positional relationship in which the second box body is placed above the first box body is only when the storage shelf is assembled, and therefore, when in use, the first box body is placed above the first box body. For such storage shelves, it is sufficient to assemble the storage shelves in a state where the vertical relationship is reversed from the state in which they are used.
