Description

This invention relates to an assembly-type table comprising a table top section formed by combining multiple tabletop members and multiple legs that support the underside of the table top section.

Conventionally, as an assembly-type table comprising a table top section formed by sequentially connecting multiple tabletop members, and multiple legs supporting the underside of this table top section, the one-touch folding table described in Patent Document 1 and the wooden stove table described in Patent Document 2 are known.

The one-touch folding table disclosed in Patent Document 1 aims to provide a portable, one-touch folding table of the hearth type that can be stored and unfolded. Specifically, it consists of a tabletop section in which two first tabletops and two second tabletops, each consisting of two tabletop parts connected at the other end, are connected so that the first tabletops face each other and the second tabletops face each other in a horizontal state, and two leg parts located below the respective connection points between the first and second tabletops, which unfold and hang down adjacent to each other at a predetermined angle when in use, and which are folded and stacked on the underside of the first or second tabletop when not in use. Furthermore, the wooden stovetop table disclosed in Patent Document 2 aims to be an inexpensive wooden stovetop table that can be easily assembled without requiring specialized skills. Specifically, it is constructed using standard lumber used in two-by-four construction as the main components. Side panels are cut to the width of the table, and vertical panels are cut to the length. Interlocking grooves are provided to fit perpendicularly to each other, forming a rectangular frame. Leg members are fixed to the corners of this frame, and connecting members are fixed between the lower parts of the leg members in the front-to-back and left-to-right directions for reinforcement. The tabletop is then fixed in a grid pattern on the framed side panels and vertical panels.

However, the conventional assembly-type tables described in Patent Document 1, etc., had the following problems.

Firstly, in the case of modular tables, an assembly process is required to connect and fix the components together. Especially in the case of frame-type tables made by combining multiple tabletop members, the number of parts increases significantly, leading to a considerable increase in overall cost. Furthermore, the assembly process requires tools such as screwdrivers, which presents a drawback for outdoor use such as camping, as it takes a considerable amount of time to assemble.

Secondly, because the components used tend to include many small metal parts such as bolts, hinges, and screws, when used outdoors, it lacks a natural feel and is prone to parts loss. Furthermore, a simple configuration limits it to a single function as a table, making it difficult to add multi-functionality and resulting in a lack of versatility and convenience.

The present invention aims to provide an assembly-type table that solves the problems present in the aforementioned background technology.

To solve the above-mentioned problems, the present invention provides an assembly-type table 1 comprising a table top section 2 formed by sequentially connecting and combining multiple table top members 2m..., and multiple leg sections 3... that support the lower surface of the table top section 2. The table 1 is characterized by having upper section 2mu... and lower section 2md... of the same length, with the upper section 2mu... and lower section 2md... overlapping and offset by a predetermined length Lo in the longitudinal direction Fe, and the same number of leg sections 3... as the table top members 2m.... Furthermore, the table top member 2m has offset surfaces 2os, 2os... protruding from both sides, with leg mounting holes 2xu, 2xd that penetrate the upper and lower surfaces, and a table top fixing section 4 that is inserted into the leg mounting holes 2xu, 2xd formed by overlapping the offset surfaces 2os, 2os of adjacent table top members 2m, 2m to fix the upper end 3u of the leg section 3 to the table top member 2m.

In this case, according to a preferred embodiment of the invention, a stepped locking portion 2ub, which widens at the top, can be formed on the inner wall surface 2uw of the leg mounting hole 2xu. Furthermore, the leg portion 3 can be constructed by stacking a pair of leg halves 3p and 3q, and a wide locking portion 16 can be provided at the upper end to lock into the stepped locking portion 2ub in the leg mounting hole 2xu. In addition, the tabletop fixing portion 4 can be constructed by first holes 31p and 31q formed through the leg portion 3, and a first wedge member 11 that is inserted into these first holes 31p and 31q and presses against the lower surface of the tabletop member 2m. On the other hand, below the tabletop member 2m, a table shelf portion 12 can be provided, which is formed by combining shelf members 12m… arranged between the leg portions 3 and 3, and a shelf fixing portion 13 can be provided to fix the shelf members 12m… to the leg portions 3…. In this configuration, the leg portion 3 can be provided with support slits 33p and 33q to support the short side portions 12ms of the shelf member 12m. The shelf fixing portion 13 can be configured with connecting members 14 that are inserted into second holes 32p and 32q formed through the leg portion 3 to lock adjacent shelf members 12m together. Furthermore, the table top portion 2 and/or the table shelf portion 12 can be provided with inwardly projecting wide locking portions 2e and/or 12e, allowing for the support of one or more auxiliary plates 17c… that close the inner openings 2o and/or 12o of the table top portion 2 and/or the table shelf portion 12.

The assembly-type table 1 according to the present invention, having such a configuration, provides the following remarkable effects.

(1) Even with a frame-type table constructed by combining multiple tabletop members 2m..., the relatively simple component shapes and minimal number of parts allow for overall cost reduction. Furthermore, since no tools such as screwdrivers are required for assembly, it can be assembled easily and quickly, even when used outdoors for camping. Additionally, because the tabletop section 2 connects the offset surfaces 2os, 2os..., the overall flatness and rigidity (strength) of the tabletop can be dramatically increased.

(2) Since all components can be constructed from woodworking parts, the natural feel when used outdoors can be enhanced, and in particular, the problem of easily losing small metal parts such as screws can be eliminated.

(3) In a preferred embodiment, if a stepped locking portion 2ub, which widens at the top, is formed on the inner wall surface 2uw of the leg mounting hole 2xu, then when fixing the leg portion 3 to the tabletop member 2m, the tabletop member 2m and the leg portion 3 can be easily fixed by simply providing a tabletop fixing portion 4 using a simple restricting means such as a wedge.

(4) In a preferred embodiment, the leg portion 3 is constructed by stacking a pair of leg halves 3p and 3q, and a wide locking portion 16 is provided at the upper end to lock into the stepped locking portion 2ub in the leg mounting hole 2xu. This not only increases the strength of the leg portion 3 through double stacking, but also allows for easy and reliable fixing and positioning of the locking portion 16.

(5) In a preferred embodiment, when constructing the tabletop fixing portion 4, if first holes 31p and 31q are formed through the leg portion 3, and first wedge members 11 are inserted into these first holes 31p and 31q to press against the lower surface of the tabletop member 2m, then the fixing can be done simply by inserting (driving in) the first wedge members 11 into the first holes 31p and 31q, allowing for easy assembly even without tools.

(6) In a preferred configuration, if a table shelf section 12 is provided below the tabletop member 2m, consisting of shelf members 12m... positioned between the leg sections 3, and shelf fixing sections 13... are provided to secure the shelf members 12m... to the leg sections 3, then, in addition to the tabletop section 2, a shelf function section (table shelf section 12) for placing dishes, food, etc., can be provided below it. This enhances multifunctionality (versatility) and convenience even in a simple configuration, and, in combination with the tabletop section 2, dramatically increases the rigidity and strength of the entire assembly table 1.

(7) In a preferred embodiment, if support slits 33p and 33q are provided in the leg portion 3 to support the short sides 12ms of the shelf members 12m, the vertical (up and down) support strength for the shelf members 12m can be further increased.

(8) In a preferred embodiment, when constructing the shelf fixing portion 13, if second holes 32p and 32q are formed through the leg portion 3, and connecting members 14 are inserted into these second holes 32p and 32q to lock and connect adjacent shelf members 12m to each other, then adjacent shelf members 12m can be connected by the connecting members 14, thereby increasing rigidity and strength in the horizontal direction (left-right direction).

(9) In a preferred embodiment, if the table top portion 2 and/or the table shelf portion 12 are provided with wide locking portions 2e and/or 12e that protrude inward, and configured to support one or more auxiliary plates 17c… that close the inner openings 2o and/or 12o of the table top portion 2 and/or the table shelf portion 12, then it is possible to easily switch between a first usage mode without using the auxiliary plates 17c…, i.e., a first usage mode in which a space for a bonfire is provided inside the table top portion 2, and a second usage mode in which the auxiliary plates 17c… are used, i.e., a second usage mode in which a single flat table without openings or a second usage mode that provides a larger storage space is possible, thereby further enhancing multifunctionality (versatility) and convenience.

Next, preferred embodiments of the present invention will be described in detail with reference to the drawings.

First, the components used in the assembly-type table 1 according to this embodiment will be described based on Figure 2, with reference to each figure.

Figure 2 shows the smallest unit components used in the assembly-type table 1. In this embodiment, the assembly-type table 1 does not use metal parts such as screws, washers, bolts, and nuts. It can be formed from a wood panel having a predetermined thickness, specifically about 10-20 mm.

As shown in Figure 2, the components consist of: upper plate sections 2mu (6 pieces), lower plate sections 2md (6 pieces), shelf members 12m (6 pieces), leg halves 3p and 3q (6 pieces each), auxiliary plate 17c (1 piece), auxiliary plate 17s (2 pieces), first wedge members 11 (6 pieces), connecting members 14 (6 pieces), second wedge members 15 (6 pieces), locking parts 16 (6 pieces), and connecting pins 21 (12 pieces). The numbers in parentheses for each component indicate the number of pieces or units required per assembly table 1.

In Figure 2, 2mu represents the upper plate portion and 2md represents the lower plate portion. The top plate member 2m can be constructed using these two portions.

The upper plate portion 2mu is cut from the center outwards on one of its rectangular short sides to form a triangular V-shaped portion 2up, and cut from the center outwards on the other short side to form a triangular Valley-shaped portion 2uq. In this case, the angle at the center of the triangular V-shaped portion 2up and the angle at the center of the triangular Valley-shaped portion 2uq are both 120°. Furthermore, a rectangular elongated hole for leg mounting 2xu is formed near the triangular V-shaped portion 2up on the upper plate portion 2mu, and as shown in Figure 8, a stepped locking portion 2ub, which widens at the top, is formed on the inner wall surface 2uw of this leg mounting hole 2xu. This allows the leg portion 3, described later, to be easily fixed to the top plate member 2m by simply providing a top plate fixing portion 4 using a simple restricting means such as a wedge. Additionally, pin mounting holes 22u and 23u are formed at two predetermined spaced locations on the upper plate portion 2mu.

As shown in Figure 2, the lower plate portion 2md is provided with a wide locking portion 2e projecting inward on a part of the inner long side in the longitudinal direction Fe. Therefore, the outer shape of the lower plate portion 2md when this wide locking portion 2e is not provided is the same as that of the upper plate portion 2mu. This wide locking portion 2e allows for the arrangement and support of the three auxiliary plates 17c, 17s, 17s described later, namely, one auxiliary plate 17c placed in the center and two auxiliary plates 17s, 17s placed on both sides of this auxiliary plate 17c. Furthermore, as will be described later, a leg mounting hole 2xd is formed that coincides with the leg mounting hole 2xu of the upper plate portion 2mu when it is overlapped with another upper plate portion 2mu in an offset position. Note that the stepped locking portion 2ub described above is not formed in this leg mounting hole 2xd. Furthermore, when the upper plate portion 2mu and the lower plate portion 2md are stacked, pin mounting holes 22d and 23d are formed in the overlapping portion of the lower plate portion 2md, so that their positions coincide with the pin mounting holes 22u and 23u of the upper plate portion 2mu.

On the other hand, 12m represents a shelf member. The shelf member 12m is formed in a trapezoidal shape and is long enough to span between adjacent leg portions 3, which will be described later. In this case, a notch 12mp with a width Lw equivalent to half the thickness of the leg portion 3 is formed on one short side 12ms of the shelf member 12m, and a similar notch 12mq with the same width Lw is formed on the other short side 12ms.

Furthermore, on the lower surface of the shelf member 12m, a mounting groove 24p for the fixing part is formed perpendicular to the center of one notch 12mp, and a mounting groove 24q for the fixing part is formed perpendicular to the center of the other notch 12mq. In this case, the length of one mounting groove 24p is approximately twice the length of the other mounting groove 24q, as it serves as the insertion groove for the U-shaped connecting member 14. Additionally, locking recesses 25p and 25q for accommodating both ends of the connecting member 14 are formed inside each wedge mounting portion 24p and 24q (see Figure 7).

On the other hand, 3p and 3q represent leg halves. These leg halves 3p and 3q are superimposed and a locking portion 16 is attached to their upper ends to form the leg 3. In Figure 2, one leg half 3p shows the outer surface when forming the leg 3, and the other leg half 3q shows the inner surface when superimposed. Therefore, the leg halves 3p and 3q have the same shape except that they are symmetrical. As shown in Figure 8, the leg halves 3p and 3q have a stepped convex end portion 34p and 34q on the inner surface of their upper ends, and as shown in Figure 2, vertically elongated first holes 31p and 31q are formed near the upper ends, and vertically elongated second holes 32p and 32q are formed below these first holes 31p and 31q. Furthermore, horizontal support slits 33p and 33q are formed at intermediate vertical positions on the outer surface of each leg half 3p and 3q (upper ends of the second holes 32p and 32q), capable of accommodating the short side portions 12ms (notches 12mp and 12mq) of the shelf member 12m.

Thus, by providing support slits 33p and 33q in the leg portion 3 (leg portion halves 3p and 3q) to support the short sides 12ms of the shelf members 12m, the vertical (up and down) support strength for the shelf members 12m can be further increased.

Furthermore, as shown in Figure 8, the locking portion 16 comprises a wide locking body portion 41 formed on both the left and right sides, and a pair of gripping portions 42p and 42q provided on the lower surface of the locking body portion 41. These gripping portions 42p and 42q can grip the convex ends 34p and 34q formed by overlapping the leg halves 3p and 3q, and both sides of the locking body portion 41 can be locked to the stepped locking portions 2ub provided in the leg mounting holes 2xu.

Thus, when constructing the leg portion 3, by stacking a pair of leg halves 3p and 3q, and providing a wide locking portion 16 at the upper end that engages with the stepped locking portion 2ub in the leg mounting hole 2xu, the strength of the leg portion 3 can be increased by stacking two halves, and the fixing and positioning of the locking portion 16 can be easily and reliably performed.

11 indicates a first wedge member that is inserted into the first holes 31p and 31q and presses against the lower surface of the top plate member 2m. This first wedge member 11 and the first holes 31p and 31q form a top plate fixing part 4 that secures the upper end portion 3u of the leg portion 3, which is inserted into the aforementioned leg mounting holes 2xu and 2xd, to the top plate member 2m. By providing such a top plate fixing part 4, the top plate can be easily assembled even without tools, for example, by simply inserting (driving in) the first wedge member 11 into the first holes 31p and 31q.

14 indicates a connecting member that is inserted into the second holes 32p and 32q and engages with adjacent shelf members 12m to connect them, while 15 indicates a second wedge member that is inserted into the second holes 32p and 32q and presses the connecting member 14 in the direction of engaging with the shelf members 12m... These second holes 32p and 32q, the connecting member 14 (and the second wedge member 15) constitute the shelf fixing section 13 that secures the shelf member 12 to the leg section 3. By providing such a shelf fixing section 13, adjacent shelf members 12m can be connected using the connecting member 14, thereby increasing rigidity and strength in the horizontal direction (left-right direction).

Next, the assembly method and usage method of the modular table 1 according to this embodiment will be explained in accordance with the assembly process diagram shown in Figure 3, with reference to the respective figures.

The example assembly table 1 assumes that the components shown in Figure 2 are sold as a set product. Therefore, users can purchase the set of components and assemble it themselves.

In this case, the assembly of the modular table 1 can be carried out through a preparation step A1 in which some components are manufactured in advance, and an assembly step A2 in which the modular table 1 is assembled, as shown in Figure 3.

First, let's explain preparation step A1. Preparation step A1 involves the fabrication of the tabletop members 2m… and leg sections 3…. First, the user prepares the components (step S1). Then, as shown in Figure 4(a), the tabletop member 2m is fabricated by bonding the lower surface of the upper plate section 2mu and the upper surface of the lower plate section 2md with adhesive (step S2).

In this process, the upper plate portion 2mu and the lower plate portion 2md are bonded together facing opposite directions, so that they are in the same positional relationship as shown in Figure 2. Furthermore, a connecting pin 21 is inserted between one pin mounting hole 22u of the upper plate portion 2mu and one pin mounting hole 22d of the lower plate portion 2md to position them, and another connecting pin 21 is inserted between the other pin mounting hole 23u of the upper plate portion 2mu and the other pin mounting hole 23d of the lower plate portion 2md to position them. The grid-like hatched area Za drawn on the upper surface of the lower plate portion 2md in Figure 4(a) indicates the adhesive bonding surface.

This results in the top plate member 2m shown in Figure 4(b). The fabricated top plate member 2m has an upper plate portion 2mu and a lower plate portion 2md that overlap with a predetermined length Lo offset in the longitudinal direction Fe. The offset surfaces 2os of the upper plate portion 2mu and the lower plate portion 2md, which protrude on both sides, form a regular hexagon. The pin mounting holes 22u, 22d… and the connecting pins 21… may be fixed by press-fitting or by adhesive.

Then, the remaining upper plate sections 2mu… and lower plate sections 2md… are manufactured using the same procedure to create the top plate members 2m…. Once a total of six sets of top plate members 2m… have been manufactured, the production of the top plate members 2m… is complete (steps S3, S2…).

Next, the leg portion 3 is manufactured. In this case, as shown in Figure 5(c), a pair of leg halves 3p and 3q and one locking portion 16 are prepared. First, the leg halves 3p and 3q are bonded together with adhesive (step S4). In Figure 5(c), the grid-like hatched area Zb drawn on the back surface of one of the leg halves 3q indicates the adhesive bonding surface. Next, the pair of gripping portions 42p and 42q of the locking portion 16 are attached to the convex ends 34p and 34q at the upper ends of the bonded leg halves 3p and 3q (step S5). In this case, the positional relationship between the convex ends 34p and 34q of the leg halves 3p and 3q and the gripping portions 42p and 42q of the locking portion 16 is as shown in the X-X enlarged cross-sectional view in Figure 8. The convex ends 34p and 34q and the gripping portions 42p and 42q are bonded and fixed together with adhesive. This results in the leg portion 3 shown in Figure 5(d).

The remaining leg halves 3p, 3q, etc., and the locking parts 16, etc., are manufactured using the same procedure. Once a total of six sets of leg halves 3, etc., have been manufactured, the production of the leg halves 3 is complete (steps S6, S4, S5, etc.). This completes preparation step A1.

Next, we will explain assembly process A2. Each component, including those obtained in preparation process A1, can be brought to the location where the assembly table 1 will be used, such as a campsite, and assembled on-site.

First, prepare two tabletop members 2m, 2m, one leg 3, and one first wedge member 11. Then, as shown in Figure 6, with the lower end of the leg 3 facing upwards, attach the leg mounting hole 2xu of the offset surface 2os on the upper plate portion 2mu of one tabletop member 2m to the leg 3 from the lower end side (from above in Figure 6). Furthermore, attach the leg mounting hole 2xd of the offset surface 2os on the lower plate portion 2md of the other tabletop member 2m to the leg 3 from the lower end side (step S7).

Next, the first wedge member 11 is inserted into the first holes 31p and 31q of the leg portion 3 in this state, from the direction of arrow F1, and attached (step S8). In this case, it is desirable to leave it in a temporarily fixed state so that it does not fully insert, but allows for some movement. Furthermore, one top plate member 2m, one leg portion 3, and one first wedge member 11 are prepared, and the next prepared leg portion 3 is inserted from the upper side (downward in Figure 6) into the leg mounting hole 2xu of the offset surface 2os of the upper plate portion 2mu of the other top plate member 2m of the intermediate assembly obtained in step S7, from the lower end side, and the leg mounting hole 2xd of the offset surface 2os of the lower plate portion 2md of the next prepared top plate member 2m is attached from the lower end side of the leg portion 3.

Next, the first wedge members 11 are attached to the first holes 31p and 31q in the leg portion 3 in this state. The assembly procedure described above is then repeated for the remaining top plate members 2m... and the leg portions 3 (steps S9, S7, S8...). Once all the top plate members 2m... have been assembled, the first wedge members 11... that were temporarily fixed in six places are fully inserted and permanently secured (step S10).

Next, as shown in Figure 7(e), the first shelf member 12m is attached between a support slit 33p formed on one outer surface of an arbitrary leg 3 and a support slit 33q formed on the other surface of another leg 3 facing the outer surface of the first leg 3. Then, the second shelf member 12m is attached between a support slit 33q formed on the other outer surface of the aforementioned arbitrary leg 3 and a support slit 33p formed on one surface of the other leg 3 facing the outer surface of the first leg 3 (step S11). The positional relationship between the shelf members 12m... and the leg 3 in this state is shown in the Y-Y enlarged cross-sectional view of Figure 8.

Furthermore, in this state, as shown in Figure 7(f), the connecting member 14 is housed in the wedge mounting portion 24p provided on one shelf member 12m, and moved by arrow F2 to insert it into the second holes 32p and 32q, while simultaneously mounting both ends of the connecting member 14 so that they are housed in the locking recess 25p of one shelf member 12m and the locking recess 25q of the other shelf member 12m (step S12). Next, as shown in Figure 7(g), the second wedge member 15 is inserted into the second holes 32p and 32q from the direction of arrow F3 and mounted (step S13). In this case, it is desirable to leave it in a temporarily fixed state so that it does not fully insert but allows for some movement.

The same procedure described above is applied to the remaining shelf members 12m, connecting members 14…, and second wedge members 15… (steps S14, S11, S12, S13…). Once all shelf members 12m… are assembled, the six temporarily fixed second wedge members 15… are fully inserted and permanently secured (step S15). This completes the assembly table 1 shown in Figure 1.

Thus, in this embodiment, the assembly table 1, by providing a table shelf section 12 formed by shelf members 12m... positioned between the leg sections 3 and 3 below the tabletop member 2m, and shelf fixing sections 13... that secure the shelf members 12m... to the leg sections 3, can be provided in addition to the tabletop section 2, below which a shelf function section (table shelf section 12) can be provided for placing dishes, food, etc. Therefore, even with a simple configuration, multi-functionality (versatility) and convenience can be enhanced, and the rigidity and strength of the entire assembly table 1 can be dramatically increased by combining it with the tabletop section 2.

Incidentally, as shown in Figure 9, the assembly table 1 according to this embodiment can be used in two selectable modes, and is equipped with optional auxiliary plates 17c, 17s, and 17s. That is, when the auxiliary plates 17c, 17s, and 17s are not used, the table can be used in the first mode, as shown in Figure 1, with the inner opening 2o of the table top 2 open. This allows for placing firewood or the like inside the table top 2 and making a bonfire.

In contrast, as shown in Figure 9, by using auxiliary plates 17c, 17s, and 17s, it can be used in a second mode of operation, resulting in a general-purpose table, i.e., a single flat table without openings. In this case, as shown in the enlarged cross-sectional view along the Z-Z line in Figure 9, the edges of the auxiliary plates 17s… are placed on the wide locking portions 2e provided on the lower plate portions 2md… of each tabletop member 2m…, and the inner opening 2o of the tabletop portion 2 is closed by the auxiliary plates 17s, 17c, and 17s in that order.

Thus, the assembly-type table 1 according to this embodiment is provided with a wide locking portion 2e projecting inward on the lower plate portion 2md, and is configured to support one or more auxiliary plates 17c... that close the inner opening 2o of the table top portion 2. Therefore, it can be easily switched between a first usage mode without using the auxiliary plates 17c..., i.e., a first usage mode that provides a space for a campfire inside the table top portion 2, and a second usage mode that uses the auxiliary plates 17c..., i.e., a second usage mode that provides a single flat table without an opening or a larger storage space. This enhances its multi-functionality (versatility) and convenience.

Therefore, according to the assembly-type table 1 of this embodiment, the basic configuration includes a top plate member 2m... having upper plate portions 2mu... and lower plate portions 2md... of the same length, with the upper plate portions 2mu... and lower plate portions 2md... overlapping with a predetermined length Lo offset in the longitudinal direction Fe, and the same number of legs 3... as the top plate members 2m..., as well as offset surfaces 2os, 2os... protruding from both sides of the top plate member 2m, with leg mounting holes 2xu, 2xd that penetrate the upper and lower surfaces, and a top plate fixing part 4 that is inserted into the leg mounting holes 2xu, 2xd formed by overlapping the offset surfaces 2os, 2os of adjacent top plate members 2m, 2m to fix the upper end 3u of the leg part 3 to the top plate member 2m. Therefore, even if it is a frame-type table made by combining multiple top plate members 2m..., it can be constructed with relatively simple part shapes and a minimum number of parts, thus achieving an overall cost reduction. Furthermore, since no tools such as screwdrivers are required for assembly, it can be assembled easily and quickly, even when used outdoors such as camping. Also, because the tabletop section 2 is constructed by connecting offset surfaces 2os, 2os…, the overall flatness and rigidity (strength) of the tabletop can be dramatically increased. In addition, since all components can be made from woodworking parts, it enhances the natural feel when used outdoors, and, in particular, eliminates the problem of easily lost parts, as small metal parts such as screws are unnecessary.

Although preferred embodiments have been described in detail above, the present invention is not limited to these embodiments. The detailed configuration, shape, materials, quantities, numerical values, etc., can be arbitrarily modified, added, or deleted without departing from the spirit of the invention.

For example, although the example shows the connecting member 14 and the second wedge member 15 being provided on the lower side of the shelf member 12m..., they may also be provided on the upper side. While providing them on the upper side is aesthetically disadvantageous, it prevents the connecting member 14 and/or the second wedge member 15 from falling due to vibration, and the locking is maintained by the weight or insertion of the connecting member 14, thus eliminating the need for the second wedge member 15. In this embodiment, an example of a hexagon-type table constructed by sequentially connecting six sets of tabletop members 2m... was given, but it is also possible to construct circular or elliptical shapes by using various polygons such as triangles and squares, as well as curved tabletop members 2m.... Furthermore, while an example was shown in which the leg portion 3 is constructed by stacking a pair of leg halves 3p and 3q, and by providing a wide locking portion 16 at the upper end that engages with the stepped locking portion 2ub in the leg mounting hole 2xu, this does not preclude the case where these are formed as a single unit. On the other hand, while a case with a table shelf portion 12 was shown, it is not an essential component.
