Summary of the Invention

Problems to be Solved by the Invention

[0005] As described above, an assembly table that can be assembled is installed on the floor via legs. In this case, depending on the purpose of use, it may be desired to change the height of the assembly table. It is also possible to change the height of the assembly table by changing the installation posture, but conventionally, an assembly table that can easily and simply change the height by changing the installation posture has not been developed.

[0006] The present disclosure has been made in consideration of such points, and an object thereof is to provide an assembly table that can easily and simply change its height by changing its installation posture.

Means for Solving the Problems

[0007] The present disclosure provides an assembly table including a pair of U-shaped bodies facing each other and a connecting body connecting the pair of U-shaped bodies. Each U-shaped body has a first leg portion, a second leg portion, and a support portion extending between the first leg portion and the second leg portion. A fixing plate is provided in one side region between the support portions of the pair of facing U-shaped bodies, and a removable plate is provided in the other side region between the support portions. The removable plate can be removed from the other side region between the support portions and attached between the first leg portions of the pair of facing U-shaped bodies.

[0008] The present disclosure provides an assembly table, wherein the removable plate covers the entire region between the first leg portions of the pair of facing U-shaped bodies.

[0009] The present disclosure provides an assembly table, wherein a plurality of protrusions are provided on a pair of side surfaces of the removable plate, and fitting grooves are formed on the support portions and the first leg portions of the pair of facing U-shaped bodies for fitting the protrusions.

[0010] The present disclosure provides an assembly table, wherein each fitting groove extends obliquely with a certain inclination angle with respect to the outer edges of the support portions and the first leg portions of the pair of facing U-shaped bodies.

[0011] The present disclosure provides an assembly table, wherein an auxiliary plate is attached between the second leg portions on the side opposite to the between the first leg portions where the removable plate is mounted of the pair of facing U-shaped bodies. The auxiliary plate is rotatable via a rotation shaft provided at an end portion of each second leg portion on the support portion side. When the assembly table is stood on the floor surface via the second leg portions, the auxiliary plate rotates from between the second leg portions to the support portion side and functions as an auxiliary leg of the assembly table.

Advantages of the Invention

[0012] As described above, according to the present disclosure, the height can be changed by easily and simply changing the installation posture.

Embodiments for Carrying Out the Invention

[0014] <First Embodiment> Hereinafter, a first embodiment of an assembled table according to the present disclosure will be described with reference to the drawings.

[0015] Figures 1 to 8 are views showing a first embodiment of an assembled table according to the present disclosure.

[0016] As shown in FIGS. 1 and 2, the assembly table 1 includes a pair of U-shaped bodies 10a and 10b facing each other, and connecting bars (connecting bodies) 17, 18, and 19 that connect the pair of U-shaped bodies 10a and 10b to each other.

[0017] Among these, each U-shaped body 10a and 10b has the same shape as each other and has a U-shaped shape when viewed from the side.

[0018] That is, each U-shaped body 10a and 10b has the same shape as each other, and each has a first leg portion 11a, 11b, a second leg portion 12a, 12b, and support portions 13a, 13b extending between the first leg portions 11a, 11b and the second leg portions 12a, 12b.

[0019] And each U-shaped body 10a and 10b is connected to each other by three connecting bars (connecting bodies) 17, 18, and 19.

[0020] Among the connecting bars 17, 18, and 19, the connecting bar 17 extends between the first leg portions 11a and 11b, and the connecting bar 17 is attached to the first leg portions 11a and 11b by attachment bolts 17a.

[0021] The connecting bar 18 extends between the second leg portions 12a and 12b, and the connecting bar 18 is attached to the second leg portions 12a and 12b by attachment bolts 18a.

[0022] The connecting bar 19 extends between the support portions 13a and 13b, and the connecting bar 19 is attached to the support portions 13a and 13b by attachment bolts 19a (see FIGS. 6 to 8).

[0023] The assembly table 1 having such a configuration is stood on the floor surface F via the first leg portions 11a, 11b and the second leg portions 12a, 12b (see FIG. 1).

[0024] As shown in FIGS. 1 and 2, a fixing plate 20 is attached to a region 20A on one side between the support portions 13a and 13b of a pair of opposing U-shaped bodies 10a and 10b, for example, the left region 20A in FIG. 1. Also, a removable plate 21 is attached to a region 21A on the other side between the support portions 13a and 13b of the pair of U-shaped bodies 10a and 10b, for example, the right region 21A in FIG. 1.

[0025] Among these, the fixing plate 20 attached to the one-side region 20A is fixed to the support portions 13a and 13b using attachment bolts 20a and 20b. Further, the removable plate 21 attached to the other-side region 21A has a plurality of, for example, two protrusions 22 and 23 provided on a pair of side surfaces as described later. By fitting the protrusions 22 and 23 provided on each side surface into fitting grooves 26 and 27 formed in the pair of support portions 13a and 13b, the removable plate 21 can be attached to the other-side region 21A between the support portions 13a and 13b.

[0026] Also, remove the protrusions 22 and 23 of the removable plate 21 from the fitting grooves 26 and 27, and remove the removable plate 21 from the other-side region 21A between the support portions 13a and 13b. Then, stand the pair of U-shaped bodies 10a and 10b upright on the floor surface F via the second leg portions 12a and 12b. And by fitting the protrusions 22 and 23 of the removable plate 21 into the fitting grooves 27 of the pair of support portions 13a and 13b and the fitting grooves 28 of the pair of first leg portions 11a and 11b, the removable plate 21 can be attached between the first leg portions 11a and 11b of the pair of opposing U-shaped bodies 10a and 10b (see FIG. 2). In this case, the assembled table 1 is installed on the floor surface F at the outer edges 12c and 12d of the second leg portions 12a and 12b.

[0027] In this embodiment, the pair of opposing U-shaped bodies 10a and 10b of the assembled table 1 are made of wood, and the connecting bars 17, 18, and 19 are made of metal cylindrical bodies.

[0028] Further, the fixed plate 20 has a pair of melamine plates forming the outer surface and a paper honeycomb structure for reinforcement disposed between the pair of melamine plates, and has a planar rectangular shape as a whole. Since the outer surface of the fixed plate 20 is made of a hard melamine plate, the fixed plate 20 will not deteriorate even after continuous use for a long time. Further, the removable plate 21 is made of a wooden planar rectangular plate.

[0029] As described above, the assembly table 1 is installed on the floor surface F via the pair of first legs 11a, 11b and the pair of second legs 12a, 12b of the pair of U-shaped bodies 10a, 10b, so that the fixed plate 20 and the removable plate 21 attached between the support portions 13a, 13b of the pair of U-shaped bodies 10a, 10b can be used as a mounting table for placing an article (not shown) (see FIG. 3).

[0030] Also, by installing the assembly table 1 on the floor surface F via the pair of second legs 12a, 12b of the pair of U-shaped bodies 10a, 10b, the removable plate 21 attached between the pair of first legs 11a, 11b of the pair of U-shaped bodies 10a, 10b can be used as a mounting table for placing an article (see FIG. 4).

[0031] In the present embodiment, when the assembly table 1 is installed on the floor surface F via the pair of first legs 11a, 11b and the pair of second legs 12a, 12b, the heights of the fixed plate 20 and the removable plate 21 are relatively low. Therefore, for example, food, tea, etc. can be placed on the fixed plate 20 and the removable plate 21, and the user can sit on a sofa or the like surrounding the assembly table 1 (see FIG. 3).

[0032] On the other hand, when the assembly table 1 is installed on the floor surface F via the pair of second legs 12a, 12b, the height of the removable plate 21 attached between the pair of first legs 11a, 11b is relatively high. Therefore, for example, a personal computer or the like can be placed on the removable plate 21, and the user can sit on a chair near the assembly table 1 and operate the personal computer on the removable plate 21 (see FIG. 4).

[0033] Next, the attachment structure of the removal plate 21 will be described.

[0034] The removal plate 21 is rectangular in plan view, and two protrusions 22 and 23 are provided on each of one side surfaces (see Fig. 5).

[0035] When attaching the removal plate 21 between the pair of support portions 13a and 13b (see Fig. 1), the protrusions 22 and 23 provided on the pair of side surfaces of the removal plate 21 are fitted into the fitting grooves 26 and 27 formed on the inner surfaces of the support portions 13a and 13b.

[0036] The fitting grooves 26 and 27 linearly extend while inclining toward the pair of second leg portions 12a and 12b with an inclination angle of 45° with respect to the outer edges (the upper edges of the support portions 13a and 13b in Fig. 1) 13c and 13d of the pair of U-shaped support portions 13a and 13b facing each other.

[0037] When attaching the removal plate 21 between the pair of first leg portions 11a and 11b (see Fig. 2), it is fitted into the fitting groove 27 formed on the inner surface of the pair of support portions 13a and 13b and the fitting groove 28 formed on the inner surface of the pair of first leg portions 11a and 11b.

[0038] Both the fitting groove 27 and the fitting groove 28 linearly extend while inclining with an inclination angle of 45° with respect to the outer edges (the upper edges of the first leg portions 11a and 11b in Fig. 2) 11c and 11d of the first leg portions 11a and 11b of the corresponding pair of U-shaped bodies 10a and 10a.

[0039] In the present embodiment, since the fitting groove 27 is provided at the corner between the support portions 13a and 13b and the first leg portions 11a and 11b, it can be said that the fitting groove 27 is provided on the support portions 13a and 13b, and it can also be said that it is provided on the first leg portions 11a and 11b.

[0040] However, instead of providing the fitting groove 27 at the corner between the support portions 13a, 13b and the first leg portions 11a, 11b, the fitting groove 27 may be provided at two locations, one on the inner surface of the support portions 13a, 13b and the other on the outer surface of the first leg portions 11a, 11b. In this case, each of the fitting grooves 27 engages with the protrusions 22 of the removal plate 21.

[0041] Also, as described above, both of the fitting grooves 26, 27 extend linearly while being inclined at an inclination angle of 45° with respect to the outer edges 13c, 13d of the support portions 13a, 13b (see FIG. 8). For this reason, in FIG. 1, when attaching the removal plate 21 between the support portions 13a, 13b of a pair of U-shaped bodies 10a, 10b, the removal plate 21 can be easily attached between the pair of support portions 13a, 13b by lowering the removal plate 21 obliquely from above the support portions 13a, 13b and inserting the protrusions 22, 23 into the fitting grooves 26, 27.

[0042] Also, once the removal plate 21 is attached between the support portions 13a, 13b, even if the assembly table 1 is rotated so as to install the assembly table 1 on the floor surface F via the pair of second leg portions 12a, 12b, since the fitting grooves 26, 27 are inclined without being orthogonal to the outer edges 13c, 13d of the support portions 13a, 13b, it is difficult for the protrusions 22, 23 to come out of the fitting grooves 26, 27.

[0043] Also, both of the fitting grooves 27, 28 extend linearly while being inclined at an inclination angle of 45° with respect to the outer edges 11c, 11d of the first leg portions 11a, 11b (see FIG. 8). For this reason, in FIG. 2, when attaching the removal plate 21 between the first leg portions 11a, 11b of a pair of U-shaped bodies 10a, 10b, the removal plate 21 can be easily attached between the pair of first leg portions 11a, 11b by lowering the removal plate 21 obliquely from above the first leg portions 11a, 11b and inserting the protrusions 22, 23 into the fitting grooves 27, 28.

[0044] Once the removal plate 21 is attached between the pair of first legs 11a and 11b, even if the assembly table 1 is rotated, the fitting grooves 27 and 28 are inclined with respect to the outer edges 11c and 11d of the first legs 11a and 11b without being perpendicular thereto, so that the protrusions 22 and 23 are difficult to come off from the fitting grooves 27 and 28.

[0045] In the present embodiment, the removal plate 21 has a rectangular shape in a plane, its length is L, and its width is W. Also, the distance W1 between the pair of U-shaped bodies 10a and 10b facing each other is substantially the same as W of the removal plate 21 (see FIG. 1).

[0046] Also, the fixing plate 20 covers one side region 20A between the support portions 13a and 13b of the pair of U-shaped bodies 10a and 10b. Further, the removal plate 21 covers the other side region 21A between the support portions 13a and 13b of the pair of U-shaped bodies 10a and 10b. Therefore, the fixing plate 20 and the removal plate 21 can cover the entire region between the pair of support portions 13a and 13b.

[0047] Also, the length L of the removal plate 21 is substantially the same as the length L1 of the pair of first legs 11a and 11b and the pair of second legs 12a and 12b. Therefore, the removal plate 21 can cover the entire region between the pair of first legs 11a and 11b.

[0048] Next, the operation of the present embodiment having such a configuration will be described.

[0049] First, an assembly table 1 having a corresponding pair of U-shaped bodies 10a and 10b is prepared, and the assembly table 1 is installed on the floor surface F via a pair of first legs 11a and 11b and a pair of second legs 12a and 12b. In this case, a fixing plate 20 is attached in advance to one side region 20A between the pair of support portions 13a and 13b of the pair of U-shaped bodies 10a and 10b.

[0050] Next, lower the removal plate 21 obliquely downward from above the support portions 13a and 13b, and insert the protrusions 22 and 23 into the fitting grooves 26 and 27 provided on the inner surfaces of the pair of support portions 13a and 13b. By doing this, the removal plate 21 can be attached to the other side region 21A between the pair of support portions 13a and 13b.

[0051] In this way, the assembled table 1 installed on the floor surface F via the pair of first leg portions 11a and 11b and the pair of second leg portions 12a and 12b is obtained (see FIG. 3). <{

[0052] In this case, the fixing plate 20 and the removal plate 21 are arranged in the entire region between the pair of support portions 13a and 13b. The height of the assembled table 1 is relatively low, at H. This height H is substantially the same as the length L1 of the first leg portions 11a and 11b and the second leg portions 12a and 12b. The user can sit on a sofa or the like surrounding the assembled table 1, use the fixing plate 20 and the removal plate 21 of the assembled table 1 as a mounting table, and place food, tea, etc. on the fixing plate 20 and the removal plate 21.

[0053] Next, when the user uses the assembled table 1 such that its height becomes relatively high at H1, first, as shown in FIG. 1, raise the removal plate 21 obliquely upward from above the support portions 13a and 13b, and move the protrusions 22 and 23 along the fitting grooves 26 and 27 to remove the removal plate 21 from the support portions 13a and 13b.

[0054] Next, rotate the corresponding pair of U-shaped bodies 10a and 10b, and install the pair of U-shaped bodies 10a and 10b on the floor surface F via the pair of second leg portions 12a and 12b (see FIG. 2).

[0055] Next, lower the removal plate 21 obliquely downward from above the pair of first leg portions 11a and 11b located above, and insert the protrusions 22 and 23 into the fitting grooves 27 and 28 provided on the inner surfaces of the pair of first leg portions 11a and 11b. By doing this, the removal plate 21 can be attached between the pair of first leg portions 11a and 11b.

[0056] In this case, the removal plate 21 is disposed in the entire area between the pair of first legs 11a and 11b, and thus the assembled table 1 installed on the floor surface F via the pair of second legs 12a and 12b is obtained (see FIG. 4).

[0057] The height of the assembled table 1 is relatively high, H1. This height H1 is substantially the same as the length L2 of the pair of support portions 13a and 13b. The user sits on a chair provided near the assembled table 1. Then, using the removal plate 21 of the assembled table 1 as a mounting table, a personal computer or the like can be placed on the removal plate 21 and the personal computer can be operated.

[0058] In addition, in the present embodiment, the outer edges 11c and 11d of the pair of first legs 11a and 11b and the outer edges 12c and 12d of the pair of second legs, 12a and 12b are parallel to each other. Further, the outer edges 13c and 13d of the pair of support portions 13a and 13b are orthogonal to the outer edges 11c and 11d of the pair of first legs 11a and 11b and the outer edges 12c and 12d of the pair of second legs 12a and (see FIG. 2).

[0059] Therefore, when the assembled table 1 is installed on the floor surface F via the pair of first legs 11a and 11b and the pair of second legs 12a and 12b, the fixed plate 20 and the removal plate 21 are horizontal with respect to the floor surface F (see FIG. 3), and also when the assembled table 1 is installed on the floor surface F via the pair of second legs 12a and 12b, the removal plate 21 is horizontal with respect to the floor surface F (see FIG. 4).

[0060] In the above-described embodiment, when changing the posture of the assembly table 1 so that the height changes from a relatively low height H to a relatively high height H1, the removal plate 21 is removed from between the pair of support portions 13a and 13b of the assembly table 1 installed on the floor surface F via the pair of first leg portions 11a and 11b and the pair of second leg portions 12a and 12b (see FIG. 3). Thereafter, the pair of U-shaped bodies 10a and 10b are rotated, and after installing the assembly table 1 on the floor surface F via the pair of second leg portions 12a and 12b, the removal plate 21 is attached between the pair of first leg portions 11a and 11b (see FIG. 4).

[0061] However, it is not limited to this. The assembly table 1 may be rotated from the state shown in FIG. 3 to the state shown in FIG. 4 without removing the removal plate 21, and then the removal plate 21 may be removed from the pair of support portions 13a and 13a, and the removed removal plate 21 may be attached between the pair of first leg portions 11a and 11b.

[0062] As described above, according to the present embodiment, when the assembly table 1 is used in a state having a relatively low height H, the assembly table 1 is installed on the floor surface F via the pair of first leg portions 11a and 11b and the pair of second leg portions 12a and 12b (see FIG. 3). At this time, the height H of the assembly table 1 corresponds to the lengths L1 of the first leg portions 11a and 11b and the second leg portions 12a and 12b.

[0063] Next, when the assembly table 1 is used in a state having a relatively high height H1, the removal plate 21 is removed from between the pair of support portions 13a and 13b of the assembly table 1. Then, the pair of U-shaped bodies 10a and 10b are rotated and installed on the floor surface F via the pair of second leg portions 12a and 12b. Thereafter, the removed removal plate 21 is attached between the pair of first leg portions 11a and 11b. At this time, the height H1 of the assembly table 1 corresponds to the length L2 of the support portions 13a and 13b.

[0064] In this way, by simply removing the removal plate 21 from the pair of support portions 13a and 13b, rotating the pair of U-shaped bodies 10a and 10b, and attaching the removal plate 21 to the pair of first leg portions 11a and 11b, the attitude of the assembly table 1 can be changed, and the height of the assembly table 1 can be easily adjusted.

[0065] Further, by lowering or raising the removal plate 21 obliquely upward into the fitting grooves 26, 27, and 28 formed in the pair of support portions 13a and 13b and the pair of first leg portions 11a and 11b, the removal plate 21 can be attached to or removed from the pair of support portions 13a and 13b or the pair of first leg portions 11a and 11b. In this case, the fitting grooves 26, 27, and 28 are inclined at 45° with respect to the outer edges 13c and 13d of the pair of support portions 13a and 13b and the outer edges 11c and 11d of the pair of first leg portions 11a and 11b. Therefore, when the assembly table 1 is installed on the floor surface F via the pair of first leg portions 11a and 11b and the pair of second leg portions 12a and 12b, even if the removal plate 21 attached between the pair of support portions 13a and 13b is lifted upward, the protrusions 22 and 23 do not come out of the fitting grooves 26 and 27, and the removal plate 21 does not come off upward from between the pair of support portions 13a and 13b (see FIG. 3).

[0066] Also, when the assembly table 1 is installed on the floor surface F via the pair of second leg portions 12a and 12b, even if the removal plate 21 attached between the pair of first leg portions 11a and 11b is lifted upward, the protrusions 22 and 23 do not come out of the fitting grooves 27 and 28, and the removal plate 21 does not come off upward from between the pair of first leg portions 11a and 11b (see FIG. 4).

[0067] Further, since the fitting grooves 26 and 27 provided on the inner surfaces of the pair of support portions 13a and 13b extend inclinedly toward the pair of second leg portions 12a and 12b with respect to the outer edges

[0068] Furthermore, when the assembly table 1 is installed in the state shown in FIG. 3, the entire area between the pair of support portions 13a and 13b can be covered by the fixed plate 20 and the removable plate 21. Therefore, the objects on the fixed plate 20 and the removable plate 21 will not fall.

[0069] Also, when the assembly table 1 is installed in the state shown in FIG. 4, the entire area between the pair of first leg portions 11a and 11b can be covered by the removable plate 21. Therefore, the objects on the removable plate 21 will not fall.

[0070] Also, as shown in FIG. 4, when the assembly table 1 is installed on the floor surface F via the pair of second leg portions 12a and 12a, the removable plate 21 is removed from between the pair of support portions 13a and 13a. Therefore, a space portion is formed in the upper portion between the pair of support portions 13a and 13a, and the design property of the assembly table 1 itself is improved. <Second Embodiment> Next, a second embodiment of the assembly table according to the present disclosure will be described with reference to FIGS. 9 to 11.

[0071] In the second embodiment shown in FIGS. 9 to 11, an auxiliary plate 30 is rotatably provided between a pair of second leg portions 12a and 12b via a rotation shaft 31.

[0072] Other configurations are substantially the same as those of the first embodiment shown in FIGS. 1 to 8.

[0073] In the second embodiment shown in FIGS. 9 to 11, the same parts as those of the first embodiment shown in FIGS. 1 to 8 are denoted by the same reference numerals, and detailed description thereof is omitted.

[0074] As shown in FIGS. 9 to 11, the assembly table 1 includes a pair of U-shaped bodies 10a and 10b facing each other, and connecting bars (connecting bodies) 17, 18, and 19 that connect the pair of U-shaped bodies 10a and 10b to each other.

[0075] Among these, each U-shaped body 10a, 10b has the same shape as each other and has a U-shaped form when viewed from the side.

[0076] That is, each U-shaped body 10a, 10b has the same shape as each other and each has a first leg portion 11a, 11b, a second leg portion 12a, 12b, and support portions 13a, 13b extending between the first leg portions 11a, 11b and the second leg portions 12a, 12b.

[0077] And each U-shaped body 10a, 10b is connected to each other by three connecting bars (connecting bodies) 17, 18, 19.

[0078] Among the connecting bars 17, 18, 19, the connecting bar 17 extends between the first leg portions 11a, 11b, and the connecting bar 17 is attached to the first leg portions 11a, 11b by attachment bolts 17a.

[0079] The connecting bar 18 extends between the second leg portions 12a, 12b, and the connecting bar 18 is attached to the second leg portions 12a, 12b by attachment bolts 18a.

[0080] The connecting bar 19 extends between the support portions 13a, 13b, and the connecting bar 19 is attached to the support portions 13a, 13b by attachment bolts 19a (see FIGS. 6 to 8).

[0081] The assembled table 1 having such a configuration is stood on the floor surface F via the first leg portions 11a, 11b and the second leg portions 12a, 12b (see FIG. 9).

[0082] Also, as shown in FIGS. 9 to 11, a fixing plate 20 is attached to one side region 20A between the support portions 13a, 13b of a pair of opposing U-shaped bodies 10a, 10b, for example, the left side region 20A in FIG. 9. Also, a removable plate 21 is attached to the other side region 21A between the support portions 13a, 13b of the pair of U-shaped bodies 10a, 10b, for example, the right side region 21A in FIG. 9.

[0083] Of these, the fixed plate 20 attached to one side region 20A is fixed to the support portions 13a and 13b using attachment bolts 20a and 20b. Further, the removal plate 21 attached to the other side region 21A has a plurality of protrusions 22 and 23 provided on a pair of side surfaces, for example, two protrusions 22 and 23 provided on each side surface. By fitting the protrusions 22 and 23 provided on each side surface into fitting grooves 26 and 27 formed in the pair of support portions 13a and 13b, the removal plate 21 can be attached to the other side region 21A between the support portions 13a and 13b (see FIG. 1).

[0084] Note that the attachment structure of the removal plate 21 to the pair of support portions 13a and 13b is the same as the attachment structure in the first embodiment shown in FIGS. 1 and 2.

[0085] Also, the protrusions 22 and 23 of the removal plate 21 can be removed from the fitting grooves 26 and 27, and the removal plate 21 can be removed from the other side region 21A between the support portions 13a and 13b. Then, the pair of U-shaped bodies 10a and 10b are stood on the floor surface F via the second leg portions 12a and 12b, and by fitting the protrusions 22 and 23 of the removal plate 21 into the fitting grooves 27 of the pair of support portions 13a and 13b and the fitting grooves 28 of the pair of first leg portions 11a and 11b, the removal plate 21 can be attached between the first leg portions 11a and 11b of the pair of opposing U-shaped bodies 10a and 10b.

[0086] Note that the attachment structure of the removal plate 21 to the first leg portions 11a and 11b is also the same as the attachment structure in the second embodiment shown in FIGS. 1 and 2.

[0087] As described above, the assembly table 1 is installed on the floor surface F via the pair of first leg portions 11a and 11b and the pair of second leg portions 12a and 12b of the pair of U-shaped bodies 10a and 10b, so that the fixed plate 20 and the removal plate 21 attached between the support portions 13a and 13b of the pair of U-shaped bodies 10a and 10b can be used as a mounting table for mounting an article (not shown) (see FIG. 9).

[0088] Further, by installing the assembly table 1 on the floor surface F via a pair of second leg portions 12a and 12b of the pair of U-shaped bodies 10a and 10b, the removal plate 21 attached between the pair of first leg portions 11a and 11b of the pair of U-shaped bodies 10a and 10b can be used as a mounting table for placing articles (see FIG. 11).

[0089] In the present embodiment, when the assembly table 1 is installed on the floor surface F via the pair of first leg portions 11a and 11b and the pair of second leg portions 12a and 12b, the heights H of the fixed plate 20 and the removal plate 21 become relatively low. Therefore, for example, food, tea, etc. can be placed on the fixed plate 20 and the removal plate 21, and the user can sit on a sofa or the like surrounding the assembly table 1 (see FIG. 9).

[0090] On the other hand, when the assembly table 1 is installed on the floor surface F via the pair of second leg portions 12a and 12b, the height H1 of the removal plate 21 becomes relatively high. Therefore, for example, a personal computer or the like can be placed on the removal plate 21, and the user can sit on a chair near the assembly table 1 and operate the personal computer on the removal plate 21 (see FIG. 11). As shown in Fig. 11, when the assembly table 1 is installed on the floor surface F via a pair of second leg portions 12a and 12b, the height from the floor surface F to the removal plate 21 is H1. On the other hand, the length of the pair of second leg portions 12a and 12b that support the assembly table 1 in contact with the floor surface F is H, which is considerably shorter than H1, the height from the floor surface F to the removal plate 21. In the present embodiment, for example, H1, the height from the floor surface F to the removal plate 21, is 600 mm, and H, the length of the pair of second leg portions 12a and 12b in contact with the floor surface F, is, for example, 370 mm. In the assembly table 1 installed on the floor surface F via a pair of second leg portions 12a and 12b, regarding the aspect ratio, the ratio of the longitudinal length to the lateral length is considerably large. For this reason, it is conceivable that the assembly table 1 installed on the floor surface F via a pair of second leg portions 12a and 12b is installed on the floor surface F in an unstable state. In the present embodiment, as will be described later, since the auxiliary plate 30 is attached between the pair of second leg portions 12a and 12b on the side opposite to the pair of first leg portions 11a and 11b to which the removal plate 21 is attached, the stability of the assembly table 1 in which the ratio of the longitudinal length to the lateral length is considerably large can be improved by this auxiliary plate 30.

[0091] By the way, in the second embodiment, as described above, the auxiliary plate 30 is attached between the pair of first leg portions 11a and 11b to which the removal plate 21 is attached and between the pair of second leg portions 12a and 12b on the opposite side. This auxiliary plate 30 is rotatably attached to the ends of the pair of second leg portions 12a and 12b on the support portion 13a and 13b side via a rotation shaft 31 (see Figs. 9 and 10).

[0092] When the assembly table 1 is installed on the floor surface F via a pair of second leg portions 12a and 12b, the auxiliary plate 30 rotates from between the pair of second leg portions 12a and 12b toward the pair of support portions 13a and 13b side (see Fig. 11). When the assembly table 1 is installed on the floor surface F via a pair of second leg portions 12a and 12b, the auxiliary plate 30 extends on the extension lines of the pair of second leg portions 12a and 12b. At the same time, the auxiliary plate 30 is prevented from further rotating toward the pair of support portions 13a and 13b side by the fixing plate 20.

[0093] In this way, when the assembly table 1 is installed on the floor surface F via a pair of second leg portions 12a and 12b (see FIG. 11), the auxiliary plate 30 functions as an auxiliary leg that prevents the assembly table 1 from rotating to the left and falling down from the state shown in FIG. 11.

[0094] Next, the operation of the present embodiment having such a configuration will be described.

[0095] First, prepare an assembly table 1 having a corresponding pair of U-shaped bodies 10a and 10b, and install the assembly table 1 on the floor surface F via a pair of first leg portions 11a and 11b and a pair of second leg portions 12a and 12b. In this case, a fixing plate 20 is attached in advance to one side region 20A between a pair of support portions 13a and 13b of the pair of U-shaped bodies 10a and 10b.

[0096] Next, lower the removal plate 21 obliquely from above the support portions 13a and 13b, and insert the protrusions 22 and 23 into fitting grooves 26 and 27 provided on the inner surfaces of the pair of support portions 13a and 13b. By doing this, the removal plate 21 can be attached to the other side region 21A between the pair of support portions 13a and 13b.

[0097] In this way, an assembly table 1 installed on the floor surface F via a pair of first leg portions 11a and 11b and a pair of second leg portions 12a and 12b is obtained (see FIG. 9).

[0098] In this case, the fixing plate 20 and the removal plate 21 are arranged in the entire region between the pair of support portions 13a and 13b. The height of the assembly table 1 is relatively low, being H. This height H is substantially the same as the length L1 of the first leg portions 11a and 11b and the second leg portions 12a and 12b. The user can sit on a sofa or the like surrounding the assembly table 1, use the fixing plate 20 and the removal plate 21 of the assembly table 1 as a mounting table, and place food, tea, etc. on the fixing plate 20 and the removal plate 21.

[0099] Next, when the user uses the assembled table 1 such that its height becomes relatively high H1, first, as shown in FIG. 1, the removal plate 21 is lifted obliquely upward from above the support portions 13a and 13b, and the removal plate 21 is removed from the support portions 13a and 13b while moving the protrusions 22 and 23 along the fitting grooves 26 and 27.

[0100] Next, a pair of U-shaped bodies 10a and 10b corresponding thereto are rotated, and the pair of U-shaped bodies 10a and 10b are installed on the floor surface F via a pair of second leg portions 12a and 12b (see FIG. 10).

[0101] Next, the removal plate 21 is lowered obliquely downward from above with respect to a pair of upper first leg portions 11a and 11b, and the protrusions 22 and 23 are inserted into fitting grooves 27 and 28 provided on the inner surfaces of the pair of first leg portions 11a and 11b. Thereby, the removal plate 21 can be attached between the pair of first leg portions 11a and 11b.

[0102] In this case, the removal plate 21 is disposed in the entire area between the pair of first leg portions 11a and 11b, and the assembled table 1 installed on the floor surface F via the pair of second leg portions 12a and 12b is obtained in this way (see FIG. 11).

[0103] The height of the assembled table 1 is relatively high H1. This height H1 is substantially the same as the length L2 of the pair of support portions 13a and 13b. The user sits on a chair provided near the assembled table 1. Then, using the removal plate 21 of the assembled table 1 as a mounting table, a personal computer or the like can be placed on the removal plate 21 and the personal computer can be operated.

[0104] In addition, in the present embodiment, the outer edges 11c and 11d of the pair of first leg portions 11a and 11b and the outer edges 12c and 12d of the pair of second leg portions 12a and 12b are parallel to each other. Also, the outer edges 13c and 13d of the pair of support portions 13a and 13b are orthogonal to the outer edges 11c and 11d of the pair of first leg portions 11a and 11b and the outer edges 12c and 12d of the pair of second leg portions 12a and 12b.

[0105] Therefore, when the assembly table 1 is installed on the floor surface F via a pair of first leg portions 11a and 11b and a pair of second leg portions 12a and 12b, the fixed plate 20 and the removable plate 21 are horizontal with respect to the floor surface F (see FIG. 9), and when the assembly table 1 is installed on the floor surface F via the pair of second leg portions 12a and 12b, the removable plate is also horizontal with respect to the floor surface F (see FIG. 11).

[0106] And when the assembly table 1 is installed on the floor surface F via the pair of second leg portions 12a and 12b, the auxiliary plate 30 rotates from between the pair of second leg portions 12a and 12b toward the pair of support portions 13a and 13b (see FIG. 11). At this time, the auxiliary plate 30 extends on the extension lines of the pair of second leg portions 12a and 12b, and the auxiliary plate 30 is prevented from further rotating toward the pair of support portions 13a and 13b by the fixed plate 20. For this reason, it is possible to prevent the assembly table 1 from rotating to the left and falling from the state shown in FIG. 11 by the auxiliary plate 30. That is, as shown in FIG. 11, when the assembly table 1 is installed on the floor surface F via the pair of second leg portions 12a and 12b, the height from the floor surface F to the removable plate 21 is H1. On the other hand, the length of the pair of second leg portions 12a and 12b that contact the floor surface F for supporting the assembly table 1 is H, which is considerably shorter than H1, the height from the floor surface F to the removable plate 21. In this way, in the assembly table 1 installed on the floor surface F via the pair of second leg portions 12a and 12b, regarding the aspect ratio, the ratio of the vertical length to the horizontal length is considerably large, so the assembly table 1 installed on the floor surface F via the pair of second leg portions 12a and 12b is installed on the floor surface F in an unstable state. In the present embodiment, the auxiliary plate 30 is attached between the pair of second leg portions 12a and 12b, and the auxiliary plate 30 extends on the extension lines of the pair of second leg portions 12a and 12b, and is prevented from further rotating toward the pair of support portions 13a and 13b by the fixed plate 20. For this reason, it is possible to surely prevent the assembly table 1 from rotating to the left and falling from the state shown in FIG. 11 by the auxiliary plate 30. In this way, the auxiliary plate 30 can stably install the assembly table 1 on the floor surface F in which the ratio of the vertical length to the horizontal length is considerably large.
