Thus, not only the width but also the shape can be changed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a round top plate used for various furniture such as desks and tables, or kitchen utensils, and more specifically, to a rectangular hollow box. (hereinafter abbreviated as "rectangular parallelepiped Joule") as the constituent elements, and by aligning them horizontally and freely connecting them, the whole becomes a rigid body structure (hereinafter abbreviated as "rigid body connection"). Regarding a variable top plate structure.

(Prior art 1) The tops (deck) of desks, tables, etc. are used in various sizes and shapes depending on their purpose. , study desks, writing desks, and recent word processing desks in the parlor.In addition to these standing desks, there are also Japanese desks, which are traditional Japanese sitting desks.On the other hand, tables include dining tables, working tables, corner tables, etc. There are partition tables.It is natural that the tops used for these various desks and tables vary in shape and width.

Desks and tables that are used on a daily basis are placed in the inner space where they are used and function as a component of the space.
It is sufficient to use it as needed. However, if the seasons or the number of staff members change, it becomes necessary to change the size, rearrangement, or storage of desks and tables. Also, I often wish I could change not only the size but also the shape of the top plate.

To change the placement, it is enough to move it to the instep. As a mechanical device to change the area of the top plate, a part of the top plate is usually retracted for daily use by a small number of people, and when used by a large number of people, the storage part of the top plate is taken out and the area is increased. I'm trying to expand it. In addition, as proposed in Japanese Utility Model Publication No. 56-26604, etc., there are foldable desks with legs that can be folded like a tea table, kotatsu tables and conference tables with removable legs, in consideration of storage when not in use. .

[Problems to be Solved by the Invention] All of the above conventional technologies are designed to save space during storage, but the former only allows the number of users to be changed, while the latter The space required is simply reduced by a fraction. Either way, it is impossible to convert it to other uses, and there will still be dead space. On the other hand, desks and tables of any unusual shape can be obtained by special order. However, the more specific the shape, the more expensive it is because it is made to order, and furthermore, it can only be used for the intended purpose, making it increasingly impossible to use it for other purposes.

In addition, mechanisms for making the area of the top plate variable include dividing the top plate into multiple pieces and making them foldable using hinges, connecting them using connectors, or using links to separate the central part. They are made to be able to be lifted up or simply connected using bottles. These ideas are just dividing the top plate into pieces to accommodate the required area, but they still require a thick top plate material. Some use reinforcing materials to supplement their strength, but they must be long, and storing the reinforcing material itself creates another dead space.

As described above, a mechanism that allows the top plate of a desk, table, etc. to change the size and shape required depending on its use without sacrificing storage or versatility has not been realized so far.

In particular, a top plate that allows the user to freely change the shape according to the purpose other than the shape change planned at the time of design has not been realized.

Therefore, an object of the present invention is to provide a shape-variable top plate structure that can change not only its size but also its shape.

What are other objects of the invention? ! ! To provide a shape-variable top plate structure whose width and depth can be changed in units of modules by rigidly connecting a number of rectangular parallelepiped modules horizontally in a detachable and detachable manner.

Still another object of the present invention is to provide a shape-variable top plate structure that can be used as a storage space by uncoupling rectangular parallelepiped modules and stacking them when not used as a top plate, and does not require additional storage space.

Still another object of the present invention is that by appropriately selecting the width and depth of the component rectangular parallelepiped module, the upper plate of the module itself becomes part of the overall top plate, and the upper plate itself is also fixed to both side plates. To provide a top plate structure whose shape can be changed at low cost and with free selection of materials using a thin top plate partitioned into a small area because the top plate is supported.

[Means for Solving the Problems] A shape-variable top plate structure according to the present invention has a plurality of hollow spaces having rigidity (hereinafter referred to as "predetermined rigidity") that does not deform or collapse in the vertical and horizontal directions. The module is composed of a rectangular parallelepiped module, and a rigid connection means for horizontally merging the side end surfaces of these rectangular parallelepiped modules and rigidly connecting them in a removable manner.

The rigid connection means includes a plurality of sets of metal fittings, and each set of connection metal fittings is a fixture that connects and fixes the rectangular parallelepiped modules to be connected by tightening and frictionally engaging the abutting side end surfaces of the rectangular parallelepiped modules.

In addition, since the rectangular parallelepiped module is composed of at least both side plates, an upper plate, and a lower plate, it provides sufficient rigidity as a whole and provides abutting side end faces of sufficient height dimension, so that it can be rigidly connected. The fixing device allows the side end surfaces to sufficiently withstand vertical loads (bending moments).

Further, the rectangular parallelepiped module may include a basic module that is approximately square in plan view and a half module that has half the width or depth of the basic module. With this configuration, the top plate structure has the width and depth dimensions of the basic module
．． If it is set to 0, the width and depth can be changed at the instep of 0.5. In other words, the overall width and depth of the top plate structure is 0.5 times that of the basic module.

1.0x, 1.5x, 2.0x, 2.5x, 30x
...can be changed by closing.

On the other hand, the rectangular parallelepiped module has a hollow structure excluding the front and back plates, so if the rigid connections of the rectangular parallelepiped modules are released and stacked as is, they can be used from both the front and the rear as a storage space. Furthermore, if a drawer is attached to the rectangular parallelepiped module, a top plate with a drawer can be provided for a desk, table, etc. If you attach a back plate and a front plate that can be opened and closed, you can freely turn it into a convenient box furniture.

[Example] A shape-variable top plate structure according to the present invention will be described below with reference to the attached drawings.

Referring to FIGS. 1 (A> and (B)), the top plate structure indicated by the reference numeral 20 as a whole is constructed by rigidly connecting at least two rectangular parallelepiped modules M. This rectangular parallelepiped module M is It is a hollow box, and is composed of square upper and lower plates 22 and both side plates 24 as shown in the figure.

In this case, a back plate 26, which will be described later, may be provided on the rear surface, but the front surface is open.In other words, the outer end surfaces of the opposing side plates 24 of the rectangular parallelepiped module M may be rigidly connected by abutting against each other in the horizontal direction. If desired, see Figure 1 (C).
A drawer 28 can be attached to the open front side of each rectangular parallelepiped module M, as shown in FIG. Note that the dimensions of the rectangular parallelepiped module M are, for example, width and depth of 45 cm.
m, and the height should be 15 cm.

FIG. 2 is a schematic front view showing the principle of the top plate structure of the present invention. However, when the top plate structure 20 of FIG. 1 is supported by the support parts 32 on both sides thereof, a load (bending moment) that is F in the vertical direction downward on the abutting surfaces (end faces on the abutting sides) of the side plates 24 is generated. Consider the state given. This state is an extreme model assuming that the user places both elbows on the top plate structure 20 and places multiple layers on it, or that a child rides on the top plate structure 20. When a load F acts, a force f acts in the horizontal direction, that is, in the direction of uncoupling, below the connection position.

Therefore, in the "rigid connection" of the present invention, rigidity is required to sufficiently overcome the force f and make the connection strong, that is, connection rigidity in the horizontal direction.

In order to satisfy this requirement, (1) the rectangular parallelepiped module M itself must have a "predetermined rigidity" in the vertical and horizontal directions, and (2) the wall thickness (height) t of the rectangular parallelepiped module M must be set to a predetermined value. (3) It is essential that the rectangular parallelepiped modules M be tightened together so as to overcome the force f that causes the connection to be broken due to the load F. In particular, when the last condition (3) is satisfied, the surface of the side plate 24 can be easily formed into a rough surface, so the frictional engagement between the two occurs over a wide area from the condition (2), and the rectangular parallelepiped module M is in a rigidly connected state. Retained. Note that when the tightening loosens, the frictional engagement of the side plate 24 instantly disappears, so in order to compensate for this, (4
) It is preferable that both picture parallelepiped modules M are supported and complementary to each other in the vertical direction. Now, among the above-mentioned conditions, (1) and (2) can be satisfied by the structure of the rectangular parallelepiped module M. That is, referring again to FIG. 1(A), the upper and lower plates 22 and the side plates 2
4 should have sufficient strength and be sufficiently fixed to each other. Sufficient strength of the plates 22, 24 can be ensured by selecting an appropriate wall thickness depending on the material they are made of. Further, by reinforcing the back plate 26, the thickness of the plates 22 and 24 can be reduced while preventing the rectangular parallelepiped module M from being deformed. On the other hand, an example of a rigid connection means that satisfies conditions (3) and (4) will be described below with reference to FIG. 3.

FIGS. 3A to 3E illustrate the fixture 34 of the rigid coupling means. The fixing device 34 may be a normal tightening member such as a toggle, but it is said that the fixing device 34 is easy to store and aesthetically, as no protrusions are protruded from the outside of the rectangular parallelepiped module M in the fixed state, and the tightening work is easy. From the viewpoint of workability, the West German Half Elm (+-+XFELE) company's "
A join 1 fitting called MinHix (trade name) is preferred. As shown, the fixture 34 is comprised of a casing 36, bolts 38, and holes 36' and 38', respectively, drilled to attach these to the side plates, upper and lower plates of the rectangular parallelepiped module M. An inverted hemispherical concave surface 36A formed on the inner surface of the casing 36 and a hemispherical convex surface 38A formed on the head of the bolt 38.
Since both are hemispherical, the contact area between the two during tightening is much larger than that of a conventional disk type, and a stable connection can be created. At the same time, when the bolt 38 is tightened, the stroke increases, and force is generated when the bolt 38 is tightened strongly. Further, even if the bolt 38 is slightly deviated in the axial direction of the casing 36, the deviation is corrected and absorbed as the bolts 38 are tightened, and the bolts 38 are aligned and fixed together.

Actually, as in the first embodiment illustrated in FIG.
Align the casing 36 in advance perpendicular to the side surface of the side plate 24 to be connected (in the embodiment shown in FIG. 4, the front and rear surfaces of the side plate 24). ! Diameter D+'(D+') slightly larger than D1
>D+) holes 36' are drilled to a depth X with the center at a distance T from both sides. A diameter d1 of a bolt 38 is provided on the side surface of the side plate 24 concentrically with this hole 36'.
Hole 3 with a slightly larger diameter d1'(dl'>(j+))
A hole 8' is bored through the hole 36'. Therefore, the pole 1-38 inserted and fixed into the opposing hole 38'
The length of is 2T.

In the first embodiment shown in FIG.
A total of 44 pairs of pits may be placed on the front and rear surfaces of the .

If the sides of the side plates 24 to be connected have a smooth surface with insufficient friction due to the material or finish, use a suitable plastic, rubber, or wooden material containing cork that has elasticity and provides a sufficient friction surface. It is preferable to bond the thin plate 241 of 241 as N friction engagement means. By appropriately chamfering the edges and corners of the thin plate 241, it is possible to prevent danger to the user of the top plate structure 20. In addition, in order to satisfy the above-mentioned condition (4), the side surfaces of the side plates 24 (in the embodiment shown in FIG. 4, the sides of the upper and lower plates 22) are provided with bins, which are complementary members shown in FIG. 3(F), at appropriate intervals. It is also preferable to drill a hole 42' having a diameter d2'<62'> d2) slightly larger than the diameter d2 of 42.

Now, when connecting the rectangular parallelepiped modules M, referring to FIG.
Attach 6.

Next, the poll 1-38 and the bottle 42 are inserted into the holes 38' and 42' of one rectangular parallelepiped module M, respectively.

The side surfaces of the other rectangular parallelepiped module M are placed so as not to face each other, and bolts 38 and pins 42, which are protruding from one rectangular parallelepiped module M, are inserted into the holes 38' and 42', so that the end surfaces of the abutting sides abut each other. Next, when the casing 36 is rotated in the direction of the arrow in FIG. 3(C) using a screwdriver, the heads of the bolts 38 in the casing 36 are aligned with the inverted hemispherical concave surface 36A and the hemispherical convex surface as shown in FIG. 3(D). 38A are tightly engaged and attracted, and the plurality of rectangular parallelepiped modules M are tightened together in the horizontal direction, and are rigidly connected. In this way, the top plate structure 20 shown in FIG. 1(B) can be easily assembled in the state shown in FIG. 4(C). This structure 20 can be easily disassembled by reversing the above procedure, and can be assembled and disassembled any number of times.

FIG. 5 shows a top plate structure 20 in which three rectangular parallelepiped modules M are connected in the width direction by mounting the rigid connection means shown in FIG. Referring to FIG. 4, in FIG. 5, both corners are tightened with fixtures 34, and both corners and the center are complemented with complementary members 42. In this way, the width is 135
A working table with a depth of 45 cm.

The top plate structure 20 can be configured to be suitable for a study desk or a writing desk.

In addition to what is shown in FIG. 4, FIG. 6 shows a basic module (hereinafter M
Similarly, a complementary member 4 is attached to the side of the side plate 24 of the
2 is shown in the figure.The figure shows a second embodiment in which the upper and lower plates 22 are mounted on the front and rear surfaces thereof.

However, in order to avoid complicating the illustration, the rigid coupling means in FIG. 4 is omitted.

Now, according to the second embodiment of the present invention illustrated in FIG.
As shown in FIG. 7, examples of connections of various shapes and widths can be obtained.

That is, as shown in (Δ), it is also possible to rigidly connect two modules MO in the vertical and horizontal directions. Developing this, as shown in (B), four module MO
For example, a top plate structure 20 of 900 m x 90 cm for a kotatsu can be constructed by connecting them in alternating vertical and horizontal directions. If a drawer is attached to this structure 20, each user of the kotatsu can use one drawer as a storage space. Furthermore, as shown in (C), if six module MOs are connected in the same vertical and horizontal directions, a 135CII x 90cn+ dining table or working table with drawers can be constructed. Furthermore, as shown in (D), two sets of four modules MO can be configured in an L-shape. According to this configuration, each set can be used as a top plate structure 20, 20+, 202 for an office desk with a side desk or a coffee table, and when combined, it can be used as a top plate structure 20 for a conference table.
Can be used as

In FIG. 8 illustrating the third and fourth embodiments of the present invention, (A), (B), and (C) represent vertically halved modules Mll according to the third embodiment, (D), (E), F) is the fourth
3A and 3B each illustrate a transverse half-module M12 according to an embodiment; Although the illustration is simplified, the arrangement of the fixture 34 as a rigid connection means and the complementary member 42 is the same as that of the second embodiment shown in FIG. 6. In addition, the dimensions of the half module are that the basic module MO is 45C11X.
45CIIX 15CIll Tealnote, vertical half-cutting module M11 is 22.5cmx 45C1x 15CI, horizontal half-milling module M12 is 45cm+x22.5co
+x 15cIIl.

When such half-divided modules M11°M12 of FIG. 8 are used together with the basic module MO of FIG. 6, the same <5111 or 6 modules can be connected as shown in FIG. However, top plate structures of various shapes and sizes can be obtained. In other words, as shown in (A), if six modules are used, the top plate structure 20 for a standard desk with a size of 135 cm x 67.5 cm, such as a study desk for upper grades, an office desk, or a study board. can be configured. Also,(
As shown in [3>, the top plate structure 20 of the 112.5CIIIX 90c+n, which has a slightly deeper depth and is suitable for placing a book column or a bookcase on the rear part, can also be composed of six modules. Furthermore, if five modules are used as shown in (C), both sleeves M11 and M
12 can be further connected to form a sail top structure 20 with both side desks.

In the fifth embodiment of the present invention shown in FIG. 10, the rigid connection means attached to the basic rectangular parallelepiped module MO' of the top plate structure includes two fixtures 34 arranged near each side of the upper and lower plates 22. This embodiment is different from the first embodiment shown in FIG. In addition, in order to reduce the length of the bolts 38 and to reduce the weight by suppressing both sides of the side plates 24, a back plate 26 is provided near the rear surface of the module MO' to ensure a predetermined rigidity of the entire module. This prevents its deformation and crushing. The back plate 26 can be attached, for example, by attaching the upper and lower plates 22 and the side plates 2.
Cut a groove on the inner surface of the corresponding part of 4, and attach the module M.
The assembly of O' can sometimes be realized by checking wA.

The connection of this module MO' is also similar to the second practical example shown in FIG.
8 and a bottle 42, the thus prepared module MO' is faced with another module MO' to be connected, the protruding bolt 38 and bottle 42 are inserted, and the casing 36 is sequentially tightened. Disassembly can be done in the reverse order.

The feature of this fifth embodiment is that the casing 36 of the fixture 34 is not hidden even when connected in the vertical and horizontal directions, so that the casing 36 of the fixture 34 is not hidden, as in the case of FIGS. 7(B), (C), and (D). Even the sides at points P or Q where three or four corners fit together can be connected with the fixture 34, and higher connection strength can be obtained. Incidentally, in the second embodiment of FIG. 6, as shown at points P and Q, either vertical or horizontal connection is realized by only the bins 42. Of course, even in the case of the second embodiment, no problem occurs because the fixing members 34 are used to tighten both ends of the top plate structure 20 whose side surfaces are extended.

Another feature of this fifth embodiment is that it can be combined with a half module (for example, as shown in FIG.
Even if it is similar to C), only the bin 42 is connected as shown by R in (C)! , it is possible to construct a more stable rigidly connected top plate structure 20.

Still another feature of the fifth embodiment is that holes 36' and 38' are formed in the side surface of the side plate at each corner of the side plate 24 in the same manner as holes 36' and 38' are formed in the front and rear surfaces of the side plate 24 in the second embodiment shown in FIG. Hole 3
In order to avoid interference with holes 6' and 38', the dimension T had to be made sufficiently large, which made the thickness i of the side plate 24 larger than the value required for strength. This problem is avoided. This feature is the 10th
As is clear from the figure, the interference of the bottle hole 42' at the corner, which is a problem even in this fifth embodiment, can be easily avoided by appropriately selecting its length and position.

The problem with this fifth embodiment is that the four casing holes 36' formed on the back and bottom surfaces of the upper and lower plates 22 become recesses when the top plate structure is used, causing inconvenience. . However, this recess can be filled by fitting a cap 44 of approximately the same diameter as shown in FIG. 10(C) onto the casing 36 after tightening the casing 36 to form a substantially flat surface. In addition, the remaining casing hole 36' is filled by fitting a cap 46 of approximately the same diameter as shown in (D) into the casing hole 36' to form a substantially flat surface. can. Since the casing 36 of the fixture 34 is relatively expensive, the unnecessary holes 36' in the casing 36 can be replaced with a relatively inexpensive cap 46 to reduce production costs. Note that both caps 44 and 46 can be easily manufactured by plastic molding.

Furthermore, the casing hole 36' can also be positively utilized as an anchor (embedding) hole.

For example, the module MO may include a desk mat 48 having an appropriate number of legs arranged (planted, glued, integrally molded, etc.) on the back surface with dimensions that closely fit into the casing hole 36'.

Mll and M12 are placed on the top plate structure 20.

This desk pad 48 can be made of any material and can be used depending on the purpose.

Cutting mats are available for children's crafts, while rubber mats and cork boards are available for safety. In addition, beautiful wooden boards and transparent vinyl mats can be used for children's schools, glass boards for students' study spaces, thin boards of precious wood for one-story buildings, and other materials for commercial use. A metal plate such as an aluminum plate can be used in harmony with the desk. On the other hand, as a special application example of the top plate structure, desk mat 4
If a tatami mat overlay is used for 8, for example, 16 basic modules MO can be connected to create a small tatami room with drawers measuring 180C1l x 180C1 in a Western-style room of your choice.

The shape-variable top plate structure according to the present invention is rigidly connected to the desired width and shape as illustrated in FIGS. Place it on your sleeve and secure it if necessary. For storage, the modules can be dismantled, returned to their original rectangular parallelepiped modules, and stacked on top of each other, allowing them to be repurposed as a storage space or used as a storage booth.

Furthermore, the shape-variable top plate structure according to the present invention is not limited to the embodiments described above. For example, the dimensions of a rectangular parallelepiped module are 4Scm x 45cax
Not limited to 15cm, 48cmX 48CIllX 1
An appropriate combination can be selected from the viewpoint of handling and strength, such as GC11,48cax 4gCl11X 12cm. The material of the module is also laminated wood.

Wood materials such as plywood (veneer or particle board), solid plastic materials, paper materials such as hardened corrugated poles, light metals such as aluminum, or
These composite materials (hybrid materials), for example, use particle board, plastic, or aluminum plate for the parts where the casing hole 3G' and bottle hole 42' are drilled and the parts that require reinforcement, and the rest is made of the same material or thin sheets of the same material as a module. can be configured to be lightweight. In addition, the standard of the module is not limited to the basic one or the half-sized one, but also the four-quarter gJ (22.5 cm x 22.5 CIX 1
5Cil), it is possible to further increase the variation in shape and width of the top plate structure. The structure of the four-division module, for example, the arrangement and number of fixtures and complementary members serving as rigid body connection means, are different from those of the second embodiment shown in FIG. 6 and the fifth embodiment shown in FIG. 10. You can do the same.

Furthermore, the fixtures and complementary members of the rigid connection means are not limited to the combination of mini-fixes and bottles. For example, the fixing device may be a disk-type joint fitting with a pan-bottomed inner surface of the casing, a toggle-type fastening fitting, or an anchor bolt although the tightening operation becomes complicated. The point is that sufficient tightening force can be generated with a simple operation to tighten the abutting end face of the module. It is sufficient as long as it can be engaged and rigidly connected. In each of the above-mentioned embodiments, a bottle was used as a supplementary member, but if sufficient reinforcement is possible, a cap, or a split bottle or stopper such as a split stopper may also be used.In short, fixing the module with a fixture Any material may be used as long as it complements the above and can be reinforced so that the connected side surfaces do not shift from each other.

Furthermore, the arrangement and number of fixtures and complementary parts are also shown in Figures 6 and 10.
The present invention is not limited to the second embodiment and the fifth embodiment illustrated in the figures.

In other words, due to the requirement for operability during tightening, the fixture has two sides (
placed on the front, rear, and upper and lower surfaces). The complementary members are arranged on the connecting side surfaces of the bottles and caps of the embodiment, and on the two perpendicular surfaces mentioned above for the bottles. The number of these fixtures and complementary members can be selected as appropriate depending on the material of the module and the required connection strength. The point to be noted in terms of arrangement and number is that half modules and quarter υ1 modules must be able to be connected to each other and to the basic module. In other words, in terms of the basic module, the arrangement and number of modules must be symmetrical about the vertical and horizontal center lines. Further, an opening/closing door may be provided on the front surface of the hollow part of the rectangular parallelepiped module.

As described in detail above, according to the present invention, a top plate structure whose width and shape can be changed is obtained.

This change can be realized by rigidly connecting a plurality of rectangular parallelepiped modules in a horizontal direction so that they can be detached and removed, using the width and depth of the module as a unit. If you choose this unit appropriately,
Since it uses an easy-to-operate connecting means, even women and children can easily assemble and disassemble it.

Particularly for children, this task is fun because it feels like building blocks. When not used as a top plate structure, by dismantling all or part of it and stacking it, it can be used as a storage space with a storage booth. Unlike other top boards, it does not require its own storage space.
It does not create dead space. Regarding the width and depth of the module, since the top plate becomes part of the overall top plate and is fixedly supported on both sides of each module, a relatively thin top plate material can be used. Therefore, there is a wide range of materials to choose from, and even expensive materials can be used effectively without waste, leading to resource savings.

In addition, the module has a simple structure consisting of standardized upper and lower plates, side plates, and a relatively thin back plate, and many holes for rigid connection means can be simultaneously machined using a multi-axis drilling machine before assembly. Productivity on the factory line is very high, and as a result, it can be manufactured at low cost. The holes that are visible from the surface other than the connecting side are also arranged in a regular symmetrical manner, so they do not spoil the aesthetics.

It can be used as it is as a bottle hole of a hanging hook to hang school children's bags, etc., and can be covered with a cover cap if unnecessary.

In addition, if it is disassembled into modules, when purchasing or moving, it will be very easy to handle and will not take up as much space as a conventional single-plate top, and even children can easily help. become. Furthermore, the module is M43
1 is very simple, it is also easy to assemble it using a knockdown method using appropriate fixing hardware. This not only makes it easier to handle, but also eliminates waste, which is often referred to as ``carrying air'' when transporting furniture, including conventional furniture.

As described above, the shape-variable top plate structure according to the present invention is
It not only proposes a new lifestyle for users, but also brings about revolutionary changes in manufacturing and transportation for the furniture industry. In addition, in response to the depletion of resources due to over-cutting of wood, which has been particularly talked about in recent years, it can be said that it is a big effect that it helps conserve resources because it allows the use of a wide variety of materials and does not need to use them lavishly.

[Effects of the Invention] The present invention includes a plurality of hollow rectangular parallelepiped modules each having a predetermined rigidity in the vertical and horizontal directions, and the side end surfaces of these rectangular parallelepiped modules are brought into contact with each other in the horizontal direction so as to be removably rigidly connected. Not only the size but also the shape can be changed by configuring it with a rigid connection means.

Furthermore, when not used as a top plate, the rectangular parallelepiped modules can be uncoupled and stacked to be used as an organizer, eliminating the need for additional storage space.

Furthermore, by appropriately selecting the width and depth of the component rectangular parallelepiped module, the upper plate of the module itself becomes part of the overall top plate, and the upper plate itself is also fixedly supported by both side plates, so the area is small. By using a thin top plate partitioned into sections, it is possible to provide a variable-shape top plate structure with free choice of materials and at low cost.
