Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tatami corner unit, and more particularly to 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, for example.
[0002]
[Prior art]
Conventionally, as this type of tatami corner unit, a tatami mat is mounted on the upper surface of the upper lid and a plurality of boxes that have a storage section below the upper lid are combined in the horizontal direction along the wall of the living room of the building. Are known (Japanese Utility Model Publication No. 64-1535, Japanese Patent Application Laid-Open No. 11-299557). This tatami corner unit makes it possible to easily configure a Japanese-style room unit that rises about 40 cm from the surrounding floor in a part of the living room. In particular, it is possible to form a Japanese-style room that is easy for elderly people and wheelchair people to move. At the same time, the space under the tatami can be used as a storage space.
[0003]
[Problems to be solved by the invention]
However, in the Japanese Utility Model Publication No. 64-1535, storage boxes with drawers are installed in a row in a horizontal direction along a plane wall, and cannot be installed in two rows, three rows, etc. in the front-rear direction. There is a problem. Further, in the conventional drawer 9, as shown in FIG. 15, the height of the facing plate 9d facing the front plate 9b is generally the same as that of the surrounding side plate 9c. In the case of having a caster 12, if it is pulled out to the front, it is easily pulled out, which is inconvenient, especially when there is a risk of jumping outside during an earthquake, and it is dangerous if children play with mischief.
[0004]
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 the articles can be stored and taken out from the upper side. It is necessary to lift the tatami mat and the top cover every time an article is stored and taken out, and it takes time and it takes effort to lift the tatami mat if the tatami is fixed to the upper surface of the top cover. Especially, it was difficult for the elderly and the weak. Further, when the upper lid is closed, the upper lid closes vigorously, and there is a risk of pinching fingers and feet, and there is a problem that an impact sound is generated.
[0005]
Further, as shown in FIG. 16, the conventional box 4 is constructed by assembling a four-side plate 14 and a bottom plate 17 ′. In order to connect the four-side plate 14 and the bottom plate 17 ′, A long and narrow groove 30 (female) is formed on the bottom plate 17 'along the longitudinal inner surface of the four-side plate 14 so that a long and thin protrusion 31 (male) protruding from the side end surface of the bottom plate 17' is fitted. . As described above, since the actual processing is necessary on the side end surface of the bottom plate 17 ′, the thickness of the bottom plate 17 ′ needs to be a certain level or more. However, since the conventional bottom plate 17 ′ functions as a structural material that supports the load, it is difficult to reduce the thickness, and as a result, the depth of the box 4 is limited by the thickness of the bottom plate 17 ′, increasing the storage capacity. There was also a problem that they could not.
[0006]
The present invention has been invented in view of the problems of the above-described conventional example, and the object of the present invention is to arbitrarily combine an open top box and a side open box appropriately. A Japanese-style unit with tatami mats can be easily formed, the units can be freely changed and changed, and when used, all the boxes constituting the unit can be stored, and some of them can be used as drawers. The purpose of the present invention is to provide a tatami corner unit that allows easy loading and unloading of articles. Another object is to have a good appearance, and it is also easy to cope with changes in the layout of the box and the manner of connection. It is to provide a tatami corner unit, and yet another object is to prevent the drawer from being pulled out even with a caster with a simple structure. It is possible to provide a tatami corner unit that is easy to use and easy to use and can ensure safety even when an earthquake or a child rides in mischief. To provide a tatami corner unit that can open and close the top lid of the box easily with a relatively small force, can prevent the generation of impact sound when it is closed safely, and has excellent usability. The bottom plate of the box body can be made thin to increase the amount of storage and the strength of the box body can be prevented from being reduced as much as possible, and while the gap between the four-side plate and the bottom surface of the bottom plate is not formed, and the four-side plate An object of the present invention is to provide a tatami corner unit that can be easily put out at right angles to the bottom plate and can improve the assembly accuracy of the box.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, in the present invention, a plurality of box bodies 4 in which the tatami mat 2 is mounted on the upper surface of the upper lid 3 and the storage portion 5 is located below the upper lid 3 are combined in the lateral direction. It is a tatami corner unit that is installed close to a corner of a wall 6 or the like, and the box 4 facing the wall 6 or the like is composed of a box 4A having an open top surface that allows the upper lid 3 to be opened upward E. The box 4 facing the open space 8 is formed of a side-opening box 4B in which the drawer 9 can be taken in and out from the side 4a. By appropriately combining the box 4A having the shape and the box 4B having the open side surface, it is possible to easily form a Japanese-style room unit having an arbitrary number of tatami mats, and to freely change and change the unit. In use, the upper lid 3 of the open top box 4A can be opened and closed to store and remove articles. On the other hand, the drawer 9 in the open side box 4B can be opened by simply pulling it forward. The drawer 9 can be pulled out from the space 8 side to easily store and take out articles, and it is not necessary to remove the tatami 2 on the open side box 4B. This makes it easy to store and take out articles.
[0008]
Further, a saddle member 10 is attached along the width direction B to the upper end of the side surface 4a of the open side box 4B, and the front surface 10a of the saddle member 10 is moved forward F from the front surface portion 9a of the drawer 9 in the housed state. Project Because The drawer 9 can be concealed by using the padding material 10, and the appearance can be improved.
[0009]
Moreover, it is preferable to connect the box bodies 4 to each other through the padding material 10 by attaching the padding material 10 across the plurality of adjacent box bodies 4, and in this case, Since the saddle member 10 can be used to prevent the box 4 from being displaced as the drawer 9 is put in and out, and the saddle member 10 can be used to join the plurality of box members 4 together, the plurality of box members 4 can be connected to each other. This makes it easy to change the layout and coupling mode of the box body 4 simply by removing the saddle member 10.
[0010]
Further, the upper end of the facing plate 9d facing the front plate 9b of the drawer 9 protrudes higher than the peripheral portion of the facing plate 9d, and contacts the opening upper end 4b of the side surface 4a of the box 4B when the drawer 9 is pulled out. It is preferable that a possible abutting portion 27 is provided. In this case, when the drawer 9 is pulled out, the abutting portion 27 at the upper end of the facing plate 9d is higher than the periphery, so that the stopper As a result, it is possible to prevent the entire drawer 9 from being pulled out even with a caster 12, making it easier to use, eliminating the danger of jumping out in the event of an earthquake, etc. Even so, safety can be secured. Further, the abutting portion 27 of the facing plate 9d also functions to prevent the stored item in the drawer 9 from getting over the facing plate 9d and falling to the back.
[0011]
Further, the above open top box 4A and the rear part 3a of the upper lid 3 are connected via a link mechanism 11a, and the link mechanism 11a is rotatable at one end 18a, 19a on a shaft support 20 provided on the box 4A. The other end portions 18b and 19b are connected to the rear portion 3a of the upper lid 3 so as to be rotatably connected to each other. The rear link 19 and the box 4A A tension spring 21 for pulling up the rear link 19 upward is spanned between the shaft support 20 and the angle θ2 formed by the tension spring 21 and the rear link 19 becomes a right angle in the half-open state of the upper lid 3. In the fully open state and the fully closed state of the upper lid 3, the angles θ <b> 1 and θ <b> 3 formed by the tension spring 21 and the rear link 19 are not perpendicular to each other, and in the fully closed state, the weight of the upper lid 3 is the spring of the tension spring 21. In this case, when the upper lid 3 is closed, the upper lid 3 is held in its fully closed state by its own weight, and when the upper lid 3 is opened, Since the spring force of the tension spring 21 is superior, the upper lid 3 can be easily lifted with a relatively small force, and the labor can be reduced especially for elderly people and weak people. In addition, the spring force becomes maximum in the half-open state, and if the half-open state is exceeded, the spring force gradually weakens. Therefore, the upper lid 3 can be prevented from opening vigorously and hitting a person or an object. Since the tension spring 21 acts as a damper device when the cover 3 is closed, it is possible to prevent the upper lid 3 from closing with force and to pinch fingers or feet, ensuring sufficient safety, and impact sound when closing the cover 3. Can be prevented. The half-open state of the upper lid 3 referred to 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. The position can be appropriately changed depending on the setting of the connection position between the rear link 19 and the rear link 19.
[0012]
The box body 4 includes a four-side plate 14 and a bottom plate 17, and a concave step portion 25 is cut out along the inner peripheral edge of the lower end 14 a of the four-side plate 14, and the bottom plate 17 formed thinner than the four-side plate 14. The outer peripheral portion 17a is fitted into the concave step portion 25 so that the lower end 14a of the four-side plate 14 and the lower surface 17b of the bottom plate 17 are flush with each other, and the adhesive tape extends from the outer peripheral surface 14b of the four-side plate 14 to the lower surface 17b of the bottom plate 17. In this case, the depth of the box body 4 is increased by the thickness of the bottom plate 17 and the storage capacity can be increased. Therefore, even if the bottom plate 17 is thin, the strength as the box body 4 is not reduced, and the outer peripheral portion 17a of the bottom plate 17 is provided on the inner periphery of the lower end 14a of the four-side plate 14. Fits into step 25 The four-side plate 14 and the bottom plate 17 can be easily put out at right angles, and the adhesive tape 26 is pasted from the outer peripheral surface 14b of the four-side plate 14 to the lower surface 17b of the bottom plate 17, so that the four-side plate 14 and the bottom plate It is possible to prevent a gap from being formed between the two.

The tatami 2 is placed on the upper surface of the upper lid 3. It is like that. The height H of the box bodies 4A and 4B is about 40 cm, for example, but the design can be arbitrarily changed. By changing the height H of the boxes 4A and 4B, it is possible to improve the convenience of use in response to changes in the physical functions of elderly people and the like, care recipients.
[0018]
The tatami mat 2 is preferably a light and thin tatami mat. The tatami 2 may be either an integral type or a separate type with the upper lid 3. When the tatami 2 and the upper lid 3 are separate, for example, as shown in FIG. 1, the size of the tatami 2 is such that one tatami 2 can be placed across the two adjacent boxes 4B and 4B. Can be arbitrarily selected regardless of the width of the upper lid 3, and if the tatami 2 is detachably mounted on the upper lid 3, the replacement of the tatami 2, which has been difficult in the past, can be easily performed. .
[0019]
Here, the plurality of boxes 4A and 4B are formed as shown in FIG. 2 (b) and an open top box 4A in which the upper lid 3 is openable upward E as shown in FIG. 2 (a). Further, the drawer 9 is divided into two types, that is, a side-opening box 4B that allows the drawer 9 to be inserted into and removed from the front F. Referring to the example of FIG. 1, the 1 tatami rectangular type box 4 and the central semi-tatami square type box 4 facing the wall 6 are each composed of an open top box 4 </ b> A, while open. A 1 tatami rectangular type box 4 facing the space 8 is formed of a side-opening box 4B.
[0020]
As shown in FIG. 2, the upper lid 3 of the open top box 4 </ b> A has a rear end portion pivotally supported by the upper rear end of the storage portion 5, and the upper lid 3 is moved upward E from the front end side of the upper lid 3. The product can be stored and taken out from the upper surface opening of the storage unit 5 when opened. The pivot mechanism 11 of the upper lid 3 is composed of, for example, a link mechanism 11a (FIG. 11), and the upper lid 3 can be opened by a hatch type and maintained in an opened state. Further, the pivot mechanism 11 includes a damper device (not shown), which makes it easy to lift the upper lid 3, and when it is closed, the upper lid 3 is gently lowered so that it closes gently so as not to make an impact sound. Will be able to. Note that the detailed configuration of the pivot mechanism 11 of the upper lid 3 is not limited to the above configuration, and can be arbitrarily changed or modified during implementation.
[0021]
On the other hand, the drawer 9 of the open side box 4B can be pulled forward F by a caster 12, as shown in FIG. In addition, it is good also as a method of taking in / out with a slide rail instead of a caster type. A finger-hanging recess 13 serving as a handle is provided on the front surface portion 9 a of the drawer 9. Note that the number of drawers 9 stored in one box 4B may be either one or a plurality. Further, a door (not shown) that can be opened and closed is provided in front of the drawer 9 so that the drawer 9 can be taken in and out by opening the door.
[0022]
As shown in FIG. 3, a saddle member 10 is attached along the width direction B of the box 4B to the upper open end of the side surface 4a of the box 4B where the drawer 9 is put in and out. The saddle member 10 of this example is formed in an inverted L-shaped cross section, and is attached to a mounting plate 15 provided at the upper end of the opening of the side surface 4a of the box 4B by screwing or the like as shown in FIG. The front surface 10a of the saddle member 10 is set so as to protrude forward F from the front surface portion 9a of the drawer 9 in a state in which the drawer 9 is housed (the phantom line in FIG. 3A). The lower end 10b is arranged close enough not to contact the upper end of the drawer 9. Further, the upper end 10c of the saddle member 10 is arranged at a position that is higher than the upper surface of the upper lid 3 and slightly lower than the upper surface of the tatami mat 2, so that the saddle member 10 also functions as a receiving portion of the tatami mat 2. . As shown in FIG. 3B, the length of the saddle member 10 is set to a length that allows the saddle member 10 to be mounted across a plurality of adjacent boxes 4B, 4B. The plurality of box bodies 4B, 4B can be connected to each other via the.
[0023]
Further, in the example of FIG. 1, the central semi-tatami square type box 4 of the box 4 </ b> A having an open top surface is used as a box 4 </ b> C for digging table installation. The box 4C for digging table installation does not have the upper lid 3, the storage unit 5 is a furnace box, and the digging table 16 can be installed in the upper surface opening. A carpet or the like is attached to the inner side surface and the inner bottom surface of the storage unit 5. The digging table 16 includes a lifting type and a mounting type. In the case of the lifting type, the digging table 16 is moved up and down from the storing unit 5 by a lifting mechanism (not shown). It can be moved up and down between 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 end opening edge of the storage portion 5, and the legs of the stationary digging table 16 may be placed at the four corners of the rectangular frame body. When the digging table 16 is not required to be installed, the rectangular frame body is removed, the upper lid 3 is attached, and the tatami 2 is placed on the upper surface of the digging table 16 so that the box 4A can be made to function as an open top box 4A.
[0024]
Therefore, by arranging the tatami corner unit 1 having the above configuration close to the corner of the living room wall 6, a Japanese room with a predetermined number of tatami mats can be arranged just by arranging it in a part where a tatami flooring is desired, such as one corner of a living room with a large floor area. Units can be easily formed. Further, by attaching the brazing material 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 box bodies 4B and 4B adjacent to each other through the brazing material 10 are improved. They can be connected to each other, and the movement of each box 4 can be regulated by the saddle member 10. The casing 10 can be easily attached from the open space 8 side, and the box 4 can be connected to each other using the casing 10 so that the box 4 is separately attached to the wall 6 of the building. Etc., and it is not necessary to connect the box bodies 4 with conventional joint fittings, bolts, nuts, etc., and the installation work becomes very simple. In addition, it is possible to obtain a sense of unity of the tatami corner unit 1 composed of a plurality of boxes 4A and 4B by the saddle material 10, and also to remove the saddle material 10 and to change the layout and connection mode of the plurality of boxes 4 It becomes possible to easily cope with the change. Moreover, by combining the 1 tatami rectangular type box 4 and the semi-tatami square type box 4 as appropriate, a Japanese-style room unit having an arbitrary number of tatami mats can be easily formed, and a commercially available digger is provided in the central box 4. If the table 16 is placed, it can be used in various ways, such as being usable as a box 4C for installing a table, and the Japanese-style room unit can be freely reconfigured and changed.
[0025]
Next, in use, when an article is stored in or taken out from the box 4A having an open top surface, as shown in FIG. 1, the upper lid 3 of the box 4A is lifted to lift the upper surface of the storage unit 5. The opening is opened and the article can be taken in and out, and when the upper lid 3 is closed, it can be returned to the original tatami surface. On the other hand, it is not necessary to remove the tatami mat 2 on the side-opening box 4B, and by simply pulling out the drawer 9 to the front, as shown in FIG. It can be taken out. That is, while all the box bodies 4A and 4B can be used as the storage section 5, by providing the drawer 9, it is easy to put in and out articles such as clothes and magazines stored in the box body 4B. Become.
[0026]
Further, in this example, when the drawer 9 is stored, the front surface 10a of the saddle member 10 protrudes forward F from the front surface portion 9a of the drawer 9, so that the drawer 9 is hidden by the saddle member 10 and looks good. Will be better. In addition, since the upper end 10c of the saddle 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 2, the saddle member 10 serves as a receiving portion of the tatami 2 and prevents the tatami 2 from being displaced. In addition, since the eaves member 10 does not protrude from the upper surface of the tatami 2, the tatami 2 can be satisfactorily accommodated while improving safety. Thus, since the box body 4 can be prevented from being displaced due to the drawer 9 being put in and out using the padding material 10, the tatami corner unit 1 can be stored more satisfactorily.
[0027]
7 to 10 show another embodiment of the box body 4A with an open top surface, and shows an example in which the box body 4A and a bracket 3b provided on the rear portion 3a of the upper lid 3 are connected via a link mechanism 11a. ing. Here, as shown in FIG. 8, the link mechanism 11 a is configured by a parallel link including a front link 18 and a rear link 19. One end portions 18a and 19a of the front link 18 and the rear link 19 are rotatably connected to a shaft support portion 20 provided on the box 4A, and the other end portions 18b and 19b are attached to a bracket 3b provided on the rear portion 3b of the upper lid 3. It is connected rotatably. One end portion 18a of the front link 18 is rotatably connected to the shaft support portion 20 of the box 4A, and the front link 18 is rotatable about the one end portion 18a. One end 19a of the rear link 19 is located obliquely behind and below the one end 18a of the front link 18, and the other end 19b of the rear link 19 is obliquely behind and below the other end 18b of the front link 18. positioned.
[0028]
A tension spring 21 for pulling up the rear link 19 upward is bridged between the rear link 19 and the shaft support portion 20 of the box 4A. Here, the front end portion 21 a of the tension spring 21 is hooked on the hook 22 protruding from the shaft support portion 20 of the box 4 </ b> A, and the rear end portion 21 b of the tension spring 21 is one end portion 19 a rather than the central portion of the rear link 19. It is hooked on a hook 23 that protrudes from a close position. The angle θ2 formed by the tension spring 21 and the rear link 19 (imaginary line L in FIG. 8) is a right angle in the half-open state of the upper lid 3, and the tension spring 21 and the rear link are respectively in the fully-open state and the fully-closed state of the upper lid 3. The angles θ1 and θ3 with respect to 19 are configured so as not to be at right angles (θ1 <θ2 <θ3), respectively, and the weight of the upper lid 3 is configured to overcome the spring force of the tension spring 21 in the fully closed state. Yes. The half-open state of the upper lid 3 referred to 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. The position can be appropriately changed depending on the setting of the connection position between the rear link 19 and the rear link 19.
[0029]
The operation will be described. 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 are inverted, and as shown in FIG. 9A, the tension spring 21 and the rear link. 19 is an obtuse angle, the spring force P applied to the rear link 19 is distributed to the component forces P1 and P2 (P = P1 + P2), and the spring force (P1) for pulling up the rear link 19 is the own weight of the upper lid 3. The upper lid 3 is held in a fully closed state by its own weight. Further, between the fully closed state and the fully open state of the upper lid 3, there is a state where the angle θ2 formed by the tension spring 21 and the rear link 19 is a right angle (referred to as a half-open state in this example). In this half-open state, as shown in FIG. 9B, the tension spring 21 is directed in the direction orthogonal to the rear link 19 so that there is no dispersion of the spring force P, so that the force that pulls up the rear link 19 is maximized. That is, when the upper lid 3 is fully closed, the weight of the upper lid 3 is greater than the spring force, but from the beginning of the opening of the upper lid 3 to the half-open state, the spring force is gradually increased to be greater than the weight of the upper lid 3. Therefore, the upper lid 3 can be pulled up with a relatively small force, and when it is closed, if the half-open state is passed, the spring force gradually weakens and the weight of the upper lid 3 is greater, so that the upper lid 3 is gently and It can be closed reliably. Further, in the fully opened state of the upper lid 3 indicated by the phantom line in FIG. 8, the rear link 19 and the tension spring 21 are substantially V-shaped, and as shown in FIG. 9C, the tension spring 21 and the rear link 19 Since the formed angle θ3 is an acute angle, the spring force P applied to the rear link 19 is distributed to the component forces P1 ′ and P2 ′ (P = P1 ′ + P2 ′), and it is possible to prevent the upper lid 3 from opening violently and the spring force. The upper lid 3 is held in the fully open state by P1 ′.
[0030]
Thus, when the upper lid 3 of the box 4A having an open top surface is opened and an article is taken in and out, when the handle at the front portion of the upper lid 3 is pulled up, the front link 18 and the rear link 19 rise up in the front upper direction, respectively. Shifts from a horizontal fully closed state to a vertical fully open state. At this time, when the upper lid 3 is closed, the 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. Even when the tatami 2 (FIG. 1) is placed on the upper surface of the upper cover 3, the upper lid 3 can be easily lifted with a relatively small force, and the labor can be reduced especially for elderly people or those with weak bodies. In addition, the spring force is maximized in the half-open state, and the spring force gradually weakens when the half-open state is exceeded. Therefore, the upper lid 3 can be prevented from opening with force and hitting a person or an object, and the upper lid 3 is held in the full-open state. become able to. On the contrary, when the upper lid 3 is closed, the tension spring 21 acts as a damper device, so that it is possible to prevent the upper lid 3 from closing with force and to pinch fingers or feet, ensuring sufficient safety and closing. It is easy to use, such as preventing the generation of impact sound.
[0031]
Further, in this example, when the upper lid 3 is fully opened by the link mechanism 11a, the upper lid 3 stands vertically at a substantially central position of the box 4A, so that articles can be taken in and out from both the front and rear sides of the upper lid 3. Since the upper lid 3 can be opened away from the wall without being obstructed, the upper lid 3 can be fully opened without being obstructed by the wall, and the article can be more easily taken in and out.
[0032]
FIGS. 11 to 13 show another embodiment of the box 4B having an open side surface. The upper end of the facing plate 9d facing the front plate 9b of the drawer 9 with the casters 12 is connected to the upper end of the side plate 9c around the facing plate 9d. An example in which a contact portion 27 that protrudes higher than the upper end 4b of the side surface 4a of the box 4B when the drawer 9 is pulled out is provided is shown. Other configurations are the same as those of the embodiment of FIG. By the way, in the conventional case, the drawer 9 of the type that pulls forward with a puller is aligned to the same height as the direction plate 9d and the side plate 9c as shown in FIG. It pulled out easily and was inconvenient. In particular, with a caster 12, there is a danger of popping out during an earthquake, and it is dangerous if a child rides in a mischief, but in the present invention, as shown in FIG. Since the contact portion 27 that can contact the upper end 4b of the side surface 4a of the box 4B when the drawer 9 is pulled out is formed higher than the peripheral portion thereof, the contact portion 27 of the facing plate 9d It acts as a stopper, and even when the caster 12 is provided, the entire drawer 9 can be prevented 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, and safety can be ensured even if a child rides in mischief. Further, since the pull-out preventing effect can be obtained by utilizing the upper end of the facing plate 9d, there is an advantage that a dedicated member for preventing pull-out need not be separately attached to the drawer 9, and a simple structure is sufficient. In addition, by providing the contact portion 27 of the facing plate 9d over almost the entire width of the facing plate 9d, the contact portion 27 functions as a stopper for preventing the pull-out, and the storage in the drawer 9 causes the facing plate 9d to move. It also functions as a fall prevention member that prevents it from getting over and falling behind. Incidentally, when the stored item falls behind the drawer 9, it is often left as it is, and when collecting the dropped item, it is necessary to take out the drawer 9 once and extend the hand to take out the dropped item. However, in the present invention, the contact part 27 can be used to prevent the stored item from falling behind, so that it is not necessary to separately attach a dedicated member for preventing the drop to the drawer 9. In addition, in this example, as shown in FIG. 13, the drawer 9 can be easily pulled out simply by tilting the entire drawer 9 so that the abutting part 27 can pass under the upper edge of the opening. There is an advantage that the drawer 9 can be pulled out and the inside of the drawer 9 and the inside of the box body 4B can be cleaned while the structure can prevent the drawer 9 from being pulled out.

FIG. 14 shows an open top and side open box 4 with an L-shaped concave step 25 opened downward and inward along the inner periphery of the lower end 14a of the four-side plate 14 of the box 4. The thickness L2 of the bottom plate 17 is formed to be thinner (L1> L2) than the thickness L1 of the four-side plate 14, and the outer peripheral portion 17a of the thin bottom plate 17 is fitted into the recessed step portion 25. An example is shown in which the lower end 14a of the four-side plate 14 and the lower surface 17b of the bottom plate 17 are flush with each other, and the adhesive tape 26 is pasted from the outer peripheral surface 14b of the four-side plate 14 to the lower surface 17b of the bottom plate 17. . The adhesive tape 26 is preferably a stretchable tape such as a cloth tape. Other configurations are the same as those of the embodiment of FIG. Thus, the bottom plate 17 is made thinner than the four-side plate 14 and the bottom surface 17b of the bottom plate 17 is flush with the lower end 14a of the four-side plate 14, so that the depth of the box 4 is reduced by the thickness of the bottom plate 17. As a result, the amount of storage can be increased, and the load of the storage can be directly applied to the floor, so that the strength of the box 4 does not decrease even if the bottom plate 17 is thin. Incidentally, as shown in FIG. 16, the four-side plate 14 and the bottom plate 17 ′ are actually joined together so that the bottom plate 17 ′ functions as a structural material that supports the load. For this purpose, the bottom plate 17 ′ is made thin. On the other hand, in the present invention, the bottom plate 17 only serves as a decorative plate, so that the bottom plate 17 can be made as thin as possible. In addition, by fitting the outer peripheral portion 17a of the bottom plate 17 into the recessed step portion 25 cut out along the inner peripheral edge of the lower end 14a of the four-side plate 14, the four-side plate 14 and the bottom plate 17 can be easily put out at right angles. By sticking a stretchable adhesive tape 26 such as a cloth tape across the outer peripheral surface 14b of the base plate 17 from the outer peripheral surface 14b of the base plate 17, it is possible to prevent a gap from being formed between the four-sided side plate 14 and the bottom plate 17, The assembly accuracy of 4 can be improved. If the bottom plate 17 and the four-side plate 14 are nailed temporarily 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. However, there are problems in that work such as application, drying, and solidification of the adhesive is complicated and time and man-hours are required, so that work efficiency and productivity are lowered. That is, in this example, since the adhesive tape 26 is used, problems such as generation of cracks in the bottom plate 17 and labor of bonding do not occur.
