In this respect, it is common with the table S2T of the two laminated lumber top plate type described above, but since the specific configuration of the top plate 101 is different, the part related to the top plate 101 is different from the table S2T. It is signed. Except for the portion related to the top plate 101, the same reference numerals as those of the table S2T of the two laminated lumber top plate type or the corresponding portions are designated by the same reference numerals, and the description thereof will be omitted.

The difference between this table M2T and the above-mentioned table S2T is as follows.

The table M2T is different from the laminated lumber top plate type table S2T in the material and form of the top plate 101. That is, the top plate 101 of the table M2T is formed by attaching a melamine decorative plate to the surface of the core material, and the bottomed grooves 111 and 112 formed in each top plate 101 are left and right ends 111a and 112a. Is closed in the vicinity of the left and right ends 101e of the top plate 101. Both end portions 111b and 112b of the bottomed grooves 111 and 112 are configured such that the depth dimension thereof gradually decreases and becomes substantially zero at the end end positions (both ends 111a and 112a). Specifically, the bottomed grooves 111 and 112 are fitted to both ends of the groove forming member G having a certain depth dimension in each portion and both ends of the groove forming member G, and the end portions 111b and 112b of the bottomed grooves 111 and 112.

The groove forming member G and the end cap H are each made of synthetic resin, and are fitted in a state where some relative movement in the longitudinal direction is allowed. That is, the groove forming member G has a channel shape having the same cross-sectional shape in each portion, and the opening width is set to the standard groove width n described above. The end cap H is formed integrally with the cap main body Hb formed so that the bottom wall Ha gradually rises toward the outer end, and the inner end of the cap main body Hb, and is formed on the outer surface of the end portion of the groove forming member G. It is provided with a fitting portion Hc to be fitted. The groove forming member G and the end cap H are fitted in a state where some relative movement in the longitudinal direction is allowed. Specifically, the groove forming member G and the end cap H are engraved on the top plate surface f with a slight gap c left between the end surface of the groove forming member G and the cap body Hb. It is fitted in the mounting groove 101f so that it can cope with expansion and contraction of the member due to dimensional error and temperature.

Further, in this table M2T, a part of the through groove 110, not the whole, has a standard groove width n. In other words, the through groove 110 formed between the anti-use ends 101b of the top plate 101 has a standard groove width portion 110a having a constant standard groove width n and an enlarged groove wider than the standard groove width portion 110a. It has a width portion 110b. In the case of this embodiment, the opening p formed by the enlarged groove width portion 110b remains open, and no special lid is provided. The standard groove width portion 110a is set to the standard groove width n.

In this table M2T, two bottomed grooves 111 and 112 are formed on each top plate 101. Each of the bottomed grooves 111 and 112 has a standard groove width n as a whole, and has the same width dimension as the standard groove width portion 110a of the through groove 110.

Here, FIG. 57 is a front view of the shelf 9, and FIG. 58 is an enlarged side view of the shelf 9.

<Action and effect of the table according to this embodiment>
With the tables S2T and M2T having such a configuration, a plurality of grooves m (through grooves 10, 110 and bottomed grooves 11, 12, 111, 112) are exposed in parallel on the top plate surface f. The optional members 4 to 9 and the like described above can be positioned and held without using any equipment by appropriately using those grooves m. Therefore, despite the simple configuration, various options can be arranged and the usability is good.

Further, the through grooves 10 and 110 formed between the top plates 1 and 101 not only serve as a wiring insertion port for communicating the lower surface 1d and 101d sides of the top plates 1 and 101 with the upper surface 1c and 101c sides. It can also be used as a gap for passing a support column for supporting a desktop panel erected on the floor. In particular, since the through grooves 10 and 110 are continuously formed from one end to the other end in the left-right direction of the top plates 1 and 101, the place to be used can be freely selected, which is convenient.

Further, the bottomed grooves 11, 12, 111, 112 are not limited to holding and positioning the optional members 4 to 9 as described above, but can also be used, for example, to lean a smartphone SP, a tablet terminal (not shown), or the like. can. In particular, in this embodiment, since a plurality of bottomed grooves 11, 12, 111, and 112 are provided in parallel on each of the top plates 1, 101, the place of use is changed not only in the left-right direction but also in the depth direction. Can be used in various ways.

The through grooves 10 and 110 may have a constant standard groove width n as a whole like the laminated lumber top plate type table S2T, but like the melamine top plate two-sheet type table M2T. May be partially provided with a standard groove width n. The through groove 110 in the table M2T having two melamine top plates has a standard groove width portion 110a having a standard groove width n and an enlarged groove width portion 110b wider than the standard groove width portion 110a. The presence of the enlarged groove width portion 110b forms an opening p that allows the upper and lower surfaces of the top plate 101 to communicate with each other. Therefore, it is possible to insert not only wiring but also a relatively bulky outlet or connector, or a support column erected on the floor surface by using the opening p.

Further, since the standard groove width n of the through grooves 10 and 110 and the standard groove width n of the bottomed grooves 11, 12, 111 and 112 are unified, not only the appearance is good but also various options are available. When holding or positioning 4 to 9, there is a high probability that the through grooves 10, 110 and the bottomed grooves 11, 12, 111, 112 can be freely used without distinction, and the convenience is improved.

Further, in the table S2T of the laminated lumber top plate type, since the left and right ends of the bottomed grooves 11 and 12 reach the left and right ends of the top plate 1 and are opened, they are accumulated in the bottomed grooves 11 and 12. Dust can also be easily swept to the side. On the other hand, in the table M2T having two melamine top plates, the left and right end portions 111a and 112a of the bottomed grooves 111 and 112 are closed in the vicinity of the left and right both ends 101e of the top plate 101, but the closed bottomed grooves 111. Since the depth dimension of both end portions 111a and 112a of 112 is gradually reduced to be substantially zero at the endmost positions (both ends 111a and 112a), foreign matter in the bottomed grooves 111 and 112 is also present. It can be easily discharged.

Moreover, in the table M2T having a multi-layered structure in which a melamine decorative plate is attached to the surface of the core material, the bottomed grooves 111 and 112 are closed in the vicinity of the end portion of the top plate 101. The above-mentioned problem 2 can also be solved. That is, according to such a configuration, the left and right ends 101e of the top plate 2 can be completely covered with the melamine decorative plate, and there is no problem that the end treatment of the top plate 101 becomes troublesome.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the present invention.

For example, the material of the top plate is not limited to the one made of laminated lumber or the one provided with a melamine decorative plate. That is, even if a top plate made of laminated lumber is used, the present invention can be applied when both ends of the bottomed groove are closed in the vicinity of both ends of the top plate.

Further, the bottomed groove may be directly engraved on the upper surface of the top plate, but can be applied to a melamine two-sheet type table M2T or the like having a multiple structure as shown in the illustrated example without any problem. .. That is, the bottomed grooves 111 and 112 are fitted to the groove forming member G having a certain depth dimension in each portion and both ends of the groove forming member G to form the end portions 111 and 112 of the bottomed groove. If H is formed by embedding H in the upper surface of the top plate 101, it is possible to form bottomed grooves 111 and 112 having good appearance and high durability. Moreover, when such a structure is adopted, if the groove forming member G and the end cap H are fitted in a state where a slight relative movement in the longitudinal direction is allowed, the groove forming member G and the end cap H can be fitted. It is possible to absorb dimensional errors that occur between the top plate 101 and the top plate 101 and relative dimensional changes that accompany temperature changes.

In addition, various modifications may be made as long as the gist of the present invention is not impaired.
