Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tatami corner unit, and more particularly to, for example, a tatami corner unit in which a Japanese-style room unit can be easily installed in a corner of a living room of a building.

[0002]

2. Description of the Related Art Conventionally, as this type of tatami corner unit, a tatami mat is placed on the upper surface of the upper lid, and a plurality of boxes, each of which has a storage portion under the upper lid, are combined in the lateral direction.
There is known one arranged along a wall of a living room of a building (Japanese Utility Model Publication No. 64-1535, JP-A-11-29).
9557). With this tatami corner unit,
It becomes possible to easily construct a Japanese-style room unit that is about 40 cm above the floor around the living room, making it possible to create a Japanese-style room space that is especially easy for the elderly and wheelchair users to move. Will be available as a storage space.

[0003]

However, in Japanese Utility Model Publication No. 64-1535, the storage boxes with drawers are installed in a row along the plane wall.
There is a problem that two rows, three rows ... Can not be installed in the front-back direction. Further, in the conventional drawer 9, as shown in FIG. 15, the height of the facing plate 9d facing the front plate 9b is set to the side plate 9c around the front plate 9d.
Since it is generally aligned at the same height as, it is inconvenient if it is pulled out to the front, especially with the caster 12, it is inconvenient, and there is a danger of jumping out especially in the event of an earthquake, In addition, it was dangerous for a child to ride and play with mischief.

Further, in the above-mentioned Japanese Patent Application Laid-Open No. 11-299557, the upper lid is opened upward when all the boxes are used so that articles can be stored in and taken out from the boxes from above. Therefore, it is necessary to lift the tatami mat and the top lid every time the articles are stored or taken out, which is time-consuming, and when the tatami mat is fixed to the upper surface of the top lid, it is difficult to lift the tatami mat. Work is especially difficult for the elderly and the weak. Further, when closing the upper lid, the upper lid closes vigorously, there is a risk of pinching a finger or foot, and there is also a problem that an impact sound is generated.

Further, as shown in FIG. 16, the conventional box body 4 is constructed by assembling a four-circle side plate 14 and a bottom plate 17 '. The side plate 14 and the bottom plate 17 ′ are the four side plates 14
Elongated protrusions 31 formed by forming elongated grooves 30 (female fruit) along the inner surface in the longitudinal direction of the bottom plate 17 '
I try to fit (male). As described above, in the related art, since the side end surface of the bottom plate 17 ′ needs to be actually machined, the thickness of the bottom plate 17 ′ needs to be set to a certain value or more. However, since the conventional bottom plate 17 'works as a structural material that bears a load, it is difficult to make it thin. As a result, the depth of the box body 4 is limited by the thickness of the bottom plate 17', which increases the storage amount. There was also the problem of not being able to do it.

The present invention has been made in view of the above-mentioned problems of the conventional example, and its object is to appropriately combine an open top type box and a side open type box. , A Japanese-style unit with an arbitrary number of tatami mats can be easily formed, and the units can be rearranged and changed freely, and when used, all the boxes that make up the unit can be stored, and some of them can be pulled out. The purpose of the present invention is to provide a tatami corner unit that can be used as a product and can easily put items in and out.
Another object of the present invention is to provide a tatami corner unit that looks good in appearance and that can easily deal with changes in the layout of the box and the coupling mode.
Even if the drawer has casters, the drawer can be prevented from pulling out with a simple structure, making it easy to use and ensuring safety especially in the event of an earthquake or when a child gets on a mischief. The other purpose is to provide a tatami corner unit that can be opened, and the other purpose is to easily open and close the upper lid of the open top type box body with relatively small force, it is safe and it is possible to prevent the generation of impact noise when closing. , To provide an easy-to-use tatami corner unit,
Still another object is to make the bottom plate of the box thin so as to increase the storage capacity and to prevent the strength of the box from being reduced as much as possible, and yet to provide a gap between the four side plates and the bottom surface of the bottom plate. It is an object of the present invention to provide a tatami corner unit in which the four-sided side plate and the bottom plate can be easily placed at a right angle while preventing the movement of the box and the assembly accuracy of the box body can be improved.

At the upper end of the opening of the side surface 4a of the box body 4B into / from which the drawer 9 is inserted / removed, as shown in FIG.
The frame member 10 is attached along the width direction B of. The frame member 10 of this example is formed in an inverted L shape in cross section, and as shown in FIG. 4, is attached to a mounting plate 15 provided at the upper end of the opening of the side surface 4a of the box body 4B by screwing or the like. The front surface 10a of the frame member 10 is set so as to project more forward F than the front surface portion 9a of the drawer 9 in a state where the drawer 9 is housed (phantom line in FIG. 3 (a)). Bottom edge 10b
Are arranged close to each other so as not to contact the upper end of the drawer 9. Further, the upper end 10c of the frame member 10 is arranged at a position higher than the upper surface of the upper lid 3 and slightly lower than the upper surface of the tatami mat 2, whereby the frame member 10 also functions as a receiving portion of the tatami mat 2. . As shown in FIG. 3 (b), the length of the frame member 10 is set so that the frame member 10 can be mounted over a plurality of adjacent box bodies 4 </ b> B, 4 </ b> B. The plurality of boxes 4B, 4B can be connected to each other via the.

Further, in the example of FIG. 1, a box body 4A having an open top surface is provided.
Among them, the half-tatami-square type box body 4 in the center is used as a box body 4C for installing a digging table. This digging table setting box 4C does not have the upper lid 3, the storage section 5 is a furnace box, and the digging table 16 can be installed in the upper opening. Storage part 5
A carpet or the like is attached to the inner side surface and the inner bottom surface of the. The digging table 16 includes a lifting type and a mounting type. In the case of the lifting type, the raising and lowering mechanism (not shown) moves the digging table 16 to the storage position in the storage unit 5 and upward from the storage unit 5. It is possible to move up and down with the lifted use position. On the other hand, in the case of the stationary type, a rectangular frame body may be arranged at the upper opening edge of the storage section 5, and the legs of the stationary excavation table 16 may be placed at the four corners of the rectangular frame body. When it is not necessary to install the digger table 16, the rectangular frame is removed to remove the upper lid 3.
When the tatami mat 2 is attached and the tatami mat 2 is placed on the upper surface of the tatami mat, it can function as an open-top box 4A.

By arranging the tatami corner unit 1 having the above-mentioned structure close to the corner portion of the wall 6 of the living room, a predetermined tatami mat can be obtained by simply arranging the tatami floor in a corner of the living room having a large floor area. A number of Japanese-style units can be easily formed. Further, by attaching the frame member 10 to the upper ends of the openings of the side surfaces 4a of the plurality of box bodies 4B facing the open space 8, the appearance is improved and
The adjacent box bodies 4B, 4B can be connected to each other via the frame material 10, and the movement of each box body 4 can be regulated by the frame material 10. This frame 10 is an open space 8
It can be easily attached from the side, and since the box bodies 4 can be connected to each other by using the frame member 10, it is necessary to separately attach the box body 4 to the wall 6 of the building by using a fastener or the like. In addition, there is no need to connect the box bodies 4 with each other using conventional joint fittings, bolts, nuts, etc., and the installation work becomes extremely simple. Further, the frame member 10 makes it possible to obtain a sense of unity of the tatami corner unit 1 composed of the plurality of boxes 4A and 4B, and by simply removing the frame member 10, the layout of the plurality of boxes 4 and the combination mode can be improved. You will be able to easily respond to changes. Again 1
By appropriately combining the tatami rectangular type box body 4 and the semi-tatami square type box body 4, a Japanese-style room unit with an arbitrary number of tatami mats can be easily formed, and a commercially available digging table 16 is provided in the central box body 4. If you place it, you can use it as a box 4C for sitting table, etc. It can be used in various ways, and you can freely change and change the Japanese-style unit.

Next, at the time of use, when storing or taking out articles in the box body 4A having an open upper surface,
As shown in FIG. 1, by lifting the upper lid 3 of the box body 4A, the upper opening of the storage portion 5 is opened, and articles can be put in and taken out. When the upper lid 3 is closed, the original tatami mat can be restored. On the other hand, the tatami mat 2 on the side open box 4B
Does not need to be removed, and by simply pulling out the drawer 9, the articles can be stored in or taken out from the open space 8 side in the drawer 9, as shown in FIG. That is, all the boxes 4A and 4B can be used as the storage section 5, and by providing the drawer 9 together, it is possible to easily take in and out articles such as clothes and magazines stored in the box 4B. Become.

Further, in this example, when the drawer 9 is stored, the front surface 10a of the frame member 10 is the front surface portion 9a of the drawer 9.
By projecting more toward the front F, the drawer 9 is hidden by the frame member 10, and the appearance is improved. Besides,
Since the upper end 10c of the frame member 10 is arranged at a position higher than the upper surface of the upper lid 3 and lower than the upper surface of the tatami mat 2, the frame member 1
Since 0 serves as a receiving portion for the tatami mat 2, the displacement movement of the tatami mat 2 can be prevented, and since the frame member 10 does not project from the upper surface of the tatami mat 2, the tatami mat 2 can be stored well while improving safety. In this way, the frame member 10 can be used to prevent the displacement of the box body 4 associated with the withdrawal of the drawer 9, so that the tatami corner unit 1 can be stored even better.

FIGS. 7 to 10 show another embodiment of the box body 4A having an open top surface, in which the box body 4A and the bracket 3b provided on the rear portion 3a of the upper lid 3 are connected via a link mechanism 11a. An example is shown. Here, as shown in FIG. 8, the link mechanism 11a is configured by a parallel link including a front link 18 and a rear link 19. One ends 18a, 19a of the front link 18 and the rear link 19 are rotatably connected to a shaft support 20 provided on the box body 4A, and the other ends 18
b and 19b are brackets 3b provided on the rear portion 3b of the upper lid 3.
Is rotatably connected to. One end 1 of the front link 18
8a is rotatably connected to the shaft support 20 of the box 4A, and the front link 18 is rotatable about one end 18a. Further, one end 19a of the rear link 19 is located obliquely rearward and downward from the end 18a of the front link 18, and the other end 19b of the rear link 19 is obliquely rearward and downward from the other end 18b of the front link 18. positioned.

A tension spring 21 for pulling the rear link 19 upward is laid between the rear link 19 and the shaft supporting portion 20 of the box body 4A. Here, the front end portion 21a of the tension spring 21 is hooked on the hook 22 protruding from the shaft support portion 20 of the box body 4A, and the rear end portion 21b of the tension spring 21 is one end portion 19 more than the center portion of the rear link 19.
It is hooked on a hook 23 protruding from a position near a. The angle θ2 formed by the tension spring 21 and the rear link 19 (phantom line L in FIG. 8) is a right angle when the upper lid 3 is in the half-open state, and the tension spring 21 and the rear link are respectively in the fully opened and fully closed states of the upper lid 3. The angles θ1 and θ3 formed by 19 are not right angles (θ1 <
θ2 <θ3), and in the fully closed state, the weight of the upper lid 3 exceeds the spring force of the tension spring 21. The half-open state of the upper lid 3 in the present invention refers to a state in which the angle θ2 formed by the tension spring 21 and the rear link 19 is a right angle, and the magnitude of the angle in the half-open state is not particularly limited. It can be changed appropriately depending on how the connection position between the rear link 19 and the rear link 19 is set.

To explain the operation, in the fully closed state of the upper lid 3 shown by the solid line in FIG. 8, the rear link 19 and the tension spring 21 have an inverted V shape, and as shown in FIG.
Since the angle θ1 formed by the rear link 19 and the rear link 19 is an obtuse angle, the spring force P applied to the rear link 19 is component force P1, P2 (P = P
1 + P2) and the spring force (P1) for pulling up the rear link 19 is smaller than the own weight of the upper lid 3, and the upper lid 3 is held in the fully closed state by its own weight. Further, the tension spring 21 and the rear link 1 are provided between the fully closed state and the fully opened state of the upper lid 3.
There exists a state where the angle θ2 formed by 9 is a right angle (in this example, a half-open state). In this half open state, FIG.
As shown in (b), since the tension spring 21 is oriented in the direction orthogonal to the rear link 19, there is no dispersion of the spring force P, and therefore the force for pulling up the rear link 19 is maximized. That is, although the weight of the upper lid 3 exceeds the spring force when the upper lid 3 is fully closed, the spring force gradually increases and exceeds the weight of the upper lid 3 from the beginning of opening the lid 3 to the half-open state. For,
The upper lid 3 can be pulled up with a comparatively small force, and conversely, when closing the lid, if the half-opened state is exceeded, the spring force will gradually weaken and the weight of the upper lid 3 will prevail.
Can be closed quietly and surely. Further, in the fully opened state of the upper lid 3 shown by the phantom line in FIG. 8, the rear link 19 and the tension spring 21 are substantially V-shaped, and FIG.
As shown in, the angle θ3 formed by the tension spring 21 and the rear link 19 is an acute angle, so the spring force P applied to the rear link 19 is dispersed into component forces P1 ′ and P2 ′ (P = P1 ′ + P2 ′). The upper lid 3 can be prevented from being opened vigorously, and the upper lid 3 is held in a vertically fully opened state by the spring force P1 '.

Then, the upper lid 3 of the box body 4A having an open upper surface
When the handle of the front portion of the upper lid 3 is pulled up when the articles are opened and put in and out, the front link 18 and the rear link 19 respectively rise to the upper front, and the upper lid 3 shifts from the horizontal fully closed state to the vertically fully opened state. To do. At this time, when the upper lid 3 is closed, the self-weight of the upper lid 3 is greater than the spring force of the tension spring 21, and when the upper lid 3 is opened, the spring force of the tension spring 21 is greater. Tatami 2 on top of 3
Even when (FIG. 1) is placed, the upper lid 3 can be easily lifted with a relatively small force, and the labor can be reduced especially for the elderly and the weak. In addition, the spring force becomes maximum in the half-opened state, and the spring force gradually weakens when the half-opened state is exceeded, so it is possible to prevent the top cover 3 from opening vigorously and hitting people or objects, and hold the top cover 3 in the fully open state. become able to. On the contrary, when the upper lid 3 is closed, the tension spring 21 functions as a damper device, so that it is possible to prevent the upper lid 3 from closing vigorously and pinching a finger or foot, and sufficient safety can be ensured.
It also improves usability by preventing the generation of impact noise when closing.

Further, in this embodiment, when the upper lid 3 is fully opened by the link mechanism 11a, the upper lid 3 is located at a substantially central position of the box body 4A.
Since it stands upright, articles can be taken in and out from both front and rear sides of the upper lid 3, the upper lid 3 does not interfere, and the upper lid 3 can be separated from the wall and opened. It can be fully opened without being obstructed by the wall, which makes it easier to take items in and out.

11 to 13 show another embodiment of the side open type box body 4B, in which the side plate around the face plate 9d is provided at the upper end of the face plate 9d facing the front plate 9b of the drawer 9 with casters 12. An example is shown in which a contact portion 27 is provided that protrudes higher than the upper end of 9c and can contact the opening upper end 4b of the side surface 4a of the box body 4B when the drawer 9 is pulled out. Other configurations are similar to those of the embodiment of FIG. By the way, the conventional drawer 9 is a type that holds the puller and pulls it toward you.
As shown in FIG. 15, since the facing plate 9d and the side plate 9c are aligned at the same height, they were easily inconveniently pulled out when pulled out to the front, which was inconvenient. Especially caster 1
In the case of the one with 2 pieces, there is a danger of popping out in the event of an earthquake, and it is dangerous for a child to play with it by mischief, but in the present invention, as shown in FIG.
Is made higher than its peripheral portion, and when the drawer 9 is pulled out, the contact portion 27 that can contact the opening upper end 4b of the side surface 4a of the box body 4B is formed. This will act as a stopper, and even if the caster 12 is provided, it is possible to prevent the drawer 9 as a whole from being pulled out, and it becomes easy to use. In addition, there is no danger of jumping out in the event of an earthquake, etc., and it will be possible to ensure safety even if the child gets on with a trick. Further, since the pull-out preventing effect can be obtained by utilizing the upper end of the direction plate 9d, there is an advantage that a dedicated member for pulling-out prevention does not need to be separately attached to the drawer 9 and a simple structure is sufficient. In addition, by providing the abutting portion 27 of the facing plate 9d over substantially the entire width of the facing plate 9d, the abutting portion 27 has a function as a stopper for preventing pulling-out, and the stored items in the drawer 9 can serve as the facing plate 9d.
It also functions as a fall prevention member that prevents the vehicle from overcoming d and falling to the back. By the way, stored items are often left behind when they fall behind the drawer 9, and when collecting fallen objects, it is necessary to take out the drawer 9 once and stretch out to remove the fallen objects. However, according to the present invention, since the abutting portion 27 can be used to prevent the stored items from falling behind, it is not necessary to separately attach a dedicated member for the fall prevention to the drawer 9. Moreover, in this example, as shown in FIG. 13, the contact portion 27 can be easily pulled out by simply tilting the entire drawer 9 so as to pass under the upper edge of the opening. Although it has a structure capable of preventing the drawer 9 from being pulled out, there is also an advantage that the inside of the drawer 9 and the inside of the box 4B can be cleaned by pulling out the drawer 9.

FIG. 14 is a top view open side view and a side open view type box body 4 in which a concave step portion having an L-shaped cross section which opens downward and inward along the inner peripheral edge of the lower end 14a of the four side plate 14 of the box body 4. 25 is formed as a notch, and the thickness L2 of the bottom plate 17 is set to the four side plates 1
4 is formed thinner than the wall thickness L1 (L1> L2), and the outer peripheral portion 17a of the bottom plate 17 formed to be thin is fitted into the recessed step portion 25 to form the lower end 14a of the four-side plate 14 and the lower surface 17b of the bottom plate 17. And the outer peripheral surface 1 of the four-side plate 14
4b to the lower surface 17b of the bottom plate 17 and the adhesive tape 26.
It shows an example of the case where is attached. The adhesive tape 26 is preferably a stretchable tape such as a cloth tape. Other configurations are similar to those of the embodiment of FIG. Thus, the bottom plate 17 is made thinner than the four-side plate 14, and the lower surface 17b of the bottom plate 17 is attached to the lower end 14a of the four-side plate 14.
By making the bottom plate 17 flat, the depth of the box body 4 becomes deeper as much as the thickness of the bottom plate 17 is reduced, and the storage amount can be increased, and the load of the stored items is directly applied to the floor. As a result, the strength of the box body 4 does not decrease even if the bottom plate 17 is thin. By the way, conventionally, as shown in FIG. 16, since the four side plates 14 and the bottom plate 17 'are actually joined, the bottom plate 17' works as a structural material for supporting the load, and therefore the bottom plate 17 'should be thin. However, since the bottom plate 17 only functions as a decorative plate in the present invention, the bottom plate 17 can be made as thin as possible. Further, by fitting the outer peripheral portion 17a of the bottom plate 17 into the recessed step portion 25 which is cut out along the inner peripheral edge of the lower end 14a of the four-sided plate 14, the four-sided plate 14 and the bottom plate 17 can be easily extended at right angles, and the four-sided plate 14 can be easily formed. Outer peripheral surface 14
By attaching a stretchable adhesive tape 26 such as a cloth tape over the lower surface 17b of the bottom plate 17 from the b side plate 14
The gap between the bottom plate 17 and the bottom plate 17 can be prevented, and the box body 4
The assembly accuracy of can be improved. If the bottom plate 17 and the four side plates 14 are nailed together without using the adhesive tape 26, there is a problem that cracks are likely to occur when the bottom plate 17 is thin, and when using an adhesive agent. However, there is a problem that the work such as the application of the adhesive, the drying, the solidification, etc. is complicated, and the work efficiency and the productivity are lowered because it takes time and man-hours. That is, in this example, since the adhesive tape 26 is used, problems such as cracking of the bottom plate 17 and time and effort for bonding do not occur.

As described above, according to the first aspect of the invention, the tatami mat is placed on the upper surface of the upper lid, and a plurality of boxes in which the lower portion of the upper lid serves as a storage portion are combined in the lateral direction. It is a tatami corner unit that is installed close to the corner of a wall, etc., and the box facing the wall etc. is composed of an open top type box whose upper lid can be opened upward. Since the facing box is composed of a side-open type that allows drawers to be pulled in and out from the side, it is possible to combine the top-side open type and side-side open type with a suitable tatami mat. A number of Japanese-style units can be easily formed, and units can be freely rearranged and changed. In addition, when using it, you can store and take out items by opening and closing the top lid of the open top type box body, while on the other hand, you can pull out from the open space side simply by pulling out the drawer inside the side open type box body. It is easy to store and take out articles, and since it is not necessary to remove the tatami mat on the open-sided box, it is easy for the elderly and the weak to take in and take out articles. Moreover, all the boxes can be stored, and by using some of them as drawers, it is possible to easily take in and out articles while securing the storage amount.

In addition to the effect of claim 1, the invention according to claim 2 attaches a frame member along the width direction to the upper end of the side surface of the box body of the side surface open type, and attaches the front surface of this frame member. Since the drawer is projected more forward than the front part of the drawer in the stored state, if the drawer is stored, the drawer will be hidden under the frame, which will improve the appearance and help prevent crime.

In addition to the effect of claim 1, the invention according to claim 3 attaches the frame member over a plurality of adjacent box bodies so that the box bodies are connected to each other via the frame material. Since they are connected to each other, the frame can be used to prevent the box from shifting when the drawer is taken in and out, and the box can be stored well, and the frame can be used to connect multiple boxes together. By connecting it, it is not necessary to separately attach the box to the wall of the building using fasteners, or to connect it with conventional joint fittings, bolts, nuts, etc. It can be done easily and surely, and the frame material gives a sense of unity of a plurality of boxes, which improves the appearance. Further, it is possible to easily deal with the change of the layout of the box body and the coupling mode only by removing the frame member.

According to a fourth aspect of the invention, in addition to the effect of the first aspect, the drawer is pulled out to the upper end of the facing plate facing the front plate of the drawer so as to project higher than the peripheral portion of the facing plate. It is preferable to provide an abutting portion capable of abutting on the upper end of the opening of the side surface of the box body in this case.
When the drawer is pulled out, the abutting part of the face plate is higher than the peripheral part of the face plate, so it acts as a stopper, preventing the drawer from being pulled out even with a caster. In addition to being easy to use, there is no danger of jumping out in the event of an earthquake, etc., and it is possible to ensure safety even if a child gets on with a mischief. Further, the facing plate functions not only as a pull-out preventing stopper, but also as a fall prevention member for preventing stored items in the drawer from overcoming the facing plate and dropping to the back.

According to the invention of claim 5, in addition to the effect of claim 1, the box body of the top open type and the rear part of the upper lid are connected via a link mechanism, and the link mechanism has one end. Consists of a parallel link consisting of a front link and a rear link that are rotatably connected to a shaft support provided on the box body and the other end is rotatably connected to the rear part of the upper lid. A tension spring for pulling the rear link upwards is hung between the shaft support of the body, and the angle between the tension spring and the rear link is a right angle when the upper lid is half open and the upper lid is fully open. In the fully closed state, the angle between the tension spring and the rear link is not a right angle, and in the fully closed state, the weight of the top lid exceeds the spring force of the tension spring, so the top lid is closed. The weight of the top lid when When the upper lid is opened, the spring force of the tension spring exceeds the self-weight of the upper lid, so that the upper lid can be easily lifted with a relatively small force. It can reduce the labor for the person and the weak person. In addition, the spring force becomes maximum in the half-opened state, and the spring force gradually weakens when the half-opened state is exceeded, so it is possible to prevent the top lid from opening vigorously and hitting people or objects. Since the tension spring acts as a damper device when closing, it is possible to prevent the upper lid from closing forcefully and pinching fingers and feet, ensuring sufficient safety and preventing impact noise when closing. As a result, it is easy to use.

In addition to the effect of any one of claims 1 to 5, the invention according to claim 6 is characterized in that the box body is provided with a four side plate and a bottom plate, and along the inner peripheral edge of the lower end of the four side plate. The bottom plate is thin because the lower end of the four-side plate and the bottom surface of the bottom plate are flush with each other by fitting the outer peripheral part of the bottom plate, which is formed thinner than the four-side plate, into the recess part. The depth of the box body is increased by the amount of the above, and the storage amount can be increased, and the load of the stored items is directly applied to the floor. Therefore, even if the bottom plate is thin, the strength of the box body is not increased. It will not fall. That is, the bottom plate only functions as a decorative plate, and the bottom plate can be made as thin as possible.
Furthermore, by fitting the outer peripheral portion of the bottom plate into the recessed step provided on the inner peripheral edge of the lower end of the fourth peripheral side plate, it becomes easy to make the peripheral plate of the fourth peripheral side and the bottom plate at right angles, and the outer peripheral surface of the fourth peripheral side plate is bonded to the lower surface of the bottom plate. By attaching the tape, it is possible to prevent a gap from being formed between the four side plates and the bottom plate, and to improve the assembly accuracy of the box body.
