Description

The present invention relates to a table suitable for use in offices, etc.

Recently, as working styles have become more diverse, it is not uncommon for multiple people to use a relatively large table for work.

However, conventional tables of this type only have an opening in the center for passing cables through, and the top surface is flat. When arranging options such as partition panels or planting boxes, or when using a smartphone or tablet device upright, dedicated brackets or legs are necessary. As a result, when arranging a variety of options, it is necessary to have various auxiliary parts on hand, and some kind of solution is desired.

To meet such demands, it is conceivable to provide a bottomed groove on the upper surface of the tabletop, which can serve functions such as positioning options and holding a smartphone or the like upright.

However, simply using this alone would create an internal corner at both ends of the bottomed groove, which is expected to cause a problem in that it would be difficult to sweep out the dust that has accumulated inside the groove (issue 1).

These issues seem to be resolved by leaving both ends of the bottomed groove open to both ends of the top plate, but adopting such a configuration creates problems when applied to a multi-layered top plate in which a decorative plate is attached to the surface of the core material. In other words, if the ends of the bottomed groove are opened on the end faces of a multi-layered top plate, the decorative plate will be easily cut out, exposing part of the core material, and there is a concern that problems will occur in which processing the end faces of the top plate will be complicated (issue 2).

This situation is not limited to tables used by multiple people for work, but also applies to other tables.

The invention described in claim 1 aims to solve the above-mentioned problem 1.

The invention as set forth in claim 3 aims to solve the above-mentioned problem 2 in addition to the problem 1.

The table of the invention described in claim 1 is a table having a bottomed groove on the upper surface of the table top, wherein both ends of the bottomed groove are configured so that their depth dimensions gradually decrease to approximately zero at the end positions , and the bottomed groove is formed by embedding a groove forming member having a constant depth dimension at each portion and end caps which are fitted onto both ends of the groove forming member to form the ends of the bottomed groove in the upper surface of the table top .

In this specification, "groove" is not limited to a groove having a bottom in the narrow sense, but also includes a through hole that extends continuously in one direction. Therefore, a "groove with a bottom" literally means a groove having a bottom in the narrow sense, and a "through groove" means a hole that does not have a bottom and extends in one direction, penetrating vertically.

In addition, the term "table" in this invention refers to any furniture with a tabletop that can be used by multiple people.

The table of the invention described in claim 2 is the table described in claim 1 , wherein the groove forming member and the end cap are fitted together in a state where slight relative movement in the longitudinal direction is permitted.

The table of the invention described in claim 3 is the table described in claim 1 or 2 , wherein the tabletop has a multi-layered structure in which a decorative plate is attached to the surface of a core material, and both ends of the groove are blocked near both ends of the tabletop.

The present invention provides a table that can solve problems 1 and 2 above.

The following describes an embodiment of the present invention with reference to the drawings.

In this embodiment, a table with two laminated wood tops (hereinafter sometimes referred to as a "laminated wood two-top table") and a table with two melamine laminated tops (hereinafter sometimes referred to as a "melamine two-top table") are described, but the present invention is only applicable to tables with two melamine tops that have a multi-layered structure.

<Table with two laminated wood tops> (Figs. 1 to 24)
As shown in Figures 1 to 6, 17 and 18, the table S2T with two laminated wood tops is a pair of tops 1 with approximately the same depth dimension, arranged with their opposite use ends 1b facing each other, with a through groove 10 (groove m) that penetrates vertically between the opposite use ends 1b of both tops 1, and bottomed grooves 11, 12 (groove m) that are parallel to the through groove 10 are formed in the upper surface 1c of each top plate 1. The through groove 10 connects the upper surface 1c (top surface f) side and the lower surface 1d side of the top plate 1, and is shaped to allow the insertion of wiring and the passage of thin posts, etc.

The tabletop 1 is rectangular in plan view with a fixed depth dimension, and is made of thick boards made of laminated timber. The through groove 10 formed between the opposite ends 1b of the tabletops 1 is formed continuously from one end to the other in the left-right direction of the tabletop 1, as shown in Figures 1, 2, 4 to 6, 17, and 18, and has a constant standard groove width n throughout.

The bottomed grooves 11 and 12 have a width dimension that is approximately the same as the standard groove width n of the through groove 10. In this embodiment, as shown in Figures 1, 2, 4 to 6, 17 and 18, a first bottomed groove 11 near the through groove 10 and a second bottomed groove 12 near the use end 1a of the top plate 1 are provided in each tabletop 1. In this embodiment, the through groove 10 located in the center in the depth direction and the first and second bottomed grooves 11 and 12 provided in each tabletop 1 are arranged in parallel at a constant pitch. These through grooves 10 and bottomed grooves 11 and 12 are parallel to the use end 1a of the tabletop 1, and a partial through groove 13 is provided in the middle of the first bottomed groove 11, as shown in Figure 5. The partial through groove 13 has a standard groove width portion 13a having a standard groove width n substantially the same as that of the bottomed groove 11, and an enlarged groove width portion 13b wider than the standard groove width portion 13a, and the standard groove width portion 13a of the partial through groove 13 is continuous with the bottomed groove 11. More specifically, as shown in Fig. 5, the partial through groove 13 has an enlarged groove width portion 13b for forming an opening p through which a bulky outlet, connector, etc. can pass, and the standard groove width portion 13a continuing with the bottomed groove 11 is provided on both the left and right ends of the enlarged groove width portion 13b. For example, as shown in Figs. 13 and 14, the partial through groove 13 can play a role of inserting a clamp k for attaching options such as an outlet C on the top plate 1, and the clamp k inserted from the enlarged groove width portion 13b is moved laterally to engage with the standard groove width portion 13a, thereby fixing the options on the top plate 1. In this embodiment, the standard groove width portion 13a of the partial through groove 13 has an upper half portion with a standard groove width n, and a lower half portion with a reduced groove width n0 that is narrower than the standard groove width n. This reduced groove width n0 corresponds to the member thickness dimension of the clamp k.

As shown in Figures 5, 6, and 8 to 13, the enlarged groove width portion 13b of the partial through groove 13 forms an opening p that connects the upper surface 1c side and the lower surface 1d side of the top plate 1, and a lid 14 is arranged on this enlarged groove width portion 13b so that it can be opened and closed. The lid 14 is configured to reduce the effective opening width of the enlarged groove width portion 13b to a groove width corresponding to the standard groove width n in the closed position (CL), and to open the enlarged groove width portion 13b in the open position (OP).

More specifically, this table S2T has an opening p (enlarged groove width portion 13a of partial through groove 13) that penetrates the top plate 1 from top to bottom, and a lid 14 is provided in this opening p so that it can be opened and closed. As shown in Figs. 10 and 15, the lid 14 has a rectangular shape in a plan view, with the top surface 14a being flush with the top plate surface f in the closed position (CL), and has an item support surface 14b that faces upward at a position higher than the top surface 1c (top plate surface f) of the top plate 1 in the open position (OP). That is, the lid 14 has an item support surface 14b on the bottom side of the part that becomes the rotating end when opening and closing, and is configured so that the item support surface 14b faces upward in the open position (OP). This item support surface 14b is preferably used, for example, when equipment such as a personal computer PC is tilted forward toward the user and placed on the top plate surface f, as shown in Fig. 15.

The mounting structure of the lid 14 to the opening p is as follows. First, expressing this mounting structure in a higher-level concept, a first support shaft and a second support shaft are provided on either the inner surface of the opening or the outer surface of the lid facing this inner surface, with a gap between them in the depth direction of the tabletop, and a first engagement groove that engages with the first support shaft in the closed position and a second engagement groove that engages with the second support shaft are provided on the other side, so that it is possible to selectively adopt a one-way rotation mode in which the lid is rotated around the first support shaft by disengaging the second engagement groove from the second support shaft, and a two-way rotation mode in which the lid is rotated around the second support shaft by disengaging the first engagement groove from the first support shaft.

To explain in detail using reference numerals, the mounting structure of the lid body 14 in this embodiment is such that, as shown in Figures 7 to 12, a first support shaft 17 and a second support shaft 18 are protruding from the inner surface pa of the opening p at a distance in the depth direction of the top plate, and a first engagement groove 15 that engages with the first support shaft 17 in the closed position (CL) and a second engagement groove 16 that engages with the second support shaft 18 are provided on the outer surface 14c of the lid body 14, respectively. When the lid body 14 is rotated in one direction by disengaging the second engagement groove 16 from the second support shaft 18 and rotating around the first support shaft 17, the article support surface 14b faces upward.

The first and second engagement grooves 15, 16 are recessed and open on the outer surface 14c and bottom surface 14d of the lid 14, respectively. As shown in FIG. 10, the inner end of the first engagement groove 15 is provided with a bent groove portion 15a that engages with the first support shaft 17 to prevent the lid 14 from falling when the lid 14 is opened by rotating it in one direction.

As shown in FIG. 11, the second engagement groove 16 has a guide cam portion 16a that slides against the second support shaft 18 while returning the lid body 14 to the closed position, and the guide cam portion 16a is shaped so that it uses the force that returns the lid body 14 to the closed position (CL) to pull the lid body 14 in the direction in which the first support shaft 17 comes out of the bent groove portion 15a. FIG. 9 shows the state in which the lid body 14 has been removed, and FIG. 12 shows the state in which the lid body 14 is held in the closed position (CL).

The lid 14 has a pivoting end 14e arranged parallel to the use end 1a and the opposite use end 1b of the tabletop 1, and is configured so that when the lid 14 is opened in the one-way pivoting manner described above, the pivoting end 14e moves parallel to the use end 1a of the tabletop 1. On the other hand, when the lid 14 is returned to the closed position (CL), as shown in FIG. 12, the upper surface 14a of the lid 14 is flush with the tabletop surface f, and the enlarged groove width portion 13b of the partial through groove 13 is also closed, leaving an opening of the standard groove width n.

As described above, on the top surface f formed by the two top plates 1 of this table S2T, as shown in Figures 1, 2, 5 and 6, one through groove 10 formed between the two top plates 1 and two bottomed grooves 11, 12 formed on each top plate 1 are arranged in parallel with the same standard groove width n. In this embodiment, the left and right ends of the bottomed grooves 11, 12 reach the left and right ends of the top plate 1 and are open, so the bottomed grooves 11, 12 and the through grooves 10 are arranged in an orderly manner with an equal presence. In other words, the top surface f has an appearance of five parallel grooves m arranged at equal pitches. As shown in Figure 16, a smartphone SP, a tablet terminal, etc. can be leaned against the bottomed grooves 11, 12 and used.

As shown in Figures 1, 3, 4, 17, and 18, the two paired tabletops 1 are detachably attached and supported by the tabletop support 3. The tabletop support 3 comprises a number of legs 31, a number of brackets 32 that attach the upper ends of the legs 31 to the underside 1d of the tabletop 1, and tabletop support frames 38, 39 that connect the brackets 32 together and attach to the underside 1d of the tabletop 1.

That is, as shown in Figures 18 and 19, this table S2T has the upper ends of legs 31 attached via brackets 32 to bracket attachment parts q provided on the underside 1d of the table top 1, and the legs 31 are provided with fastening elements 34, 35 for fastening their upper ends to the brackets 32.

As shown in Figures 17 to 24, the bracket 32 comprises a bracket body 33 having an upward contact surface 33a that contacts the underside 1d of the tabletop 1 and a downward mounting surface 33b against which the upper end surface 31z of the leg 31 abuts, and a concealing portion 36 that is provided on the bracket body 33 and conceals the fastening elements 34, 35 when the leg 31 is fastened. The bracket 32 in this embodiment is made of, for example, aluminum die casting, and the bracket body 33 and the concealing portion 36 are molded integrally.

As shown in Figs. 19 to 22, the bracket 32 has bolt holes 33c for mounting the tabletop, which are used to screw the bracket body 33 to the tabletop 1, in a portion not covered by the concealing portion 36, and is configured so that the tabletop 1 can be detachably connected to the bracket 32 while the legs 31 remain attached to the bracket 32. Specifically, the bracket 32 has four bolt holes 33c on its outer edge, and as shown in Fig. 19, the bracket 32 can be attached to the underside 1d of the tabletop 1 by inserting mounting bolts B0 from below through the bolt holes 33c and screwing them into embedded nuts N embedded in the bracket mounting portion q of the tabletop 1.

21, the leg 31 has bolt insertion holes 31a, 31b that open to the upper end surface 31z, fastening element mounting holes 31c, 31d that open to the side surface 31x and are perpendicular to the bolt insertion holes 31a, 31b, and fastening elements (pin-shaped nuts) 34, 35 that are mounted in the fastening element mounting holes 31c, 31d and have female threaded holes 34a, 35a at positions corresponding to the bolt insertion holes 31a, 31b. The leg 31 is fastened to the bracket 32 by inserting the bolts B1, B2 that penetrate the bracket 32 from top to bottom into the bolt insertion holes 31e and screwing them into the female threaded holes 34a, 34b of the fastening element 34.

The leg 31 is made of wood, for example, and as shown in Fig. 21, at least the upper end is columnar with an inward end surface 31y facing the lower leg space and both side surfaces 31x continuing from the inward end surface 31y, and the concealing portion 36 of the bracket 32 described above is wall-shaped, partially covering the inward end surface 31y and both side surfaces 31x. That is, the leg 31 has stepped recesses 31ya, 31xa formed on the inward end surface 31y continuing from the upper end surface 31z and the upper end portions of both side surfaces 31x, and the concealing portion 36 described above is fitted externally to the stepped recesses 31ya, 31xa of the inward end surface 31y and both side surfaces 31x. The fastening element mounting holes 31c, 31d open into the stepped recessed portion 31xa on both side surfaces 31x of the leg 31, and the fastening elements 34, 35 mounted in the fastening element mounting holes 31c, 31d are completely hidden by the concealing portion 36 when the leg 31 is attached to the bracket 32.

To explain the fastening structure of the leg 31 and the bracket 32 in more detail, as shown in Figure 21, the upper end surface 31z of the leg 31 has one first bolt insertion hole 31a, two second bolt insertion holes 31b, and two female threaded holes 31ea of the embedded nuts 31e, and the side surface 31x of the leg 31 has a first fastening element mounting hole 31c perpendicular to the first bolt insertion hole 31a and a second fastening element mounting hole 31d perpendicular to the second bolt insertion hole 31b. In addition, the first fastening element mounting hole 31c has a pin-shaped first fastening element 34 having a female threaded hole 34a at a position corresponding to the first bolt insertion hole 31a, and the second fastening element mounting hole 31d has a pin-shaped second fastening element 35 having a female threaded hole 35b at a position corresponding to the second bolt insertion hole 31b. The first fastening bolt B1, which has been inserted into the first bolt insertion hole 31a of the leg 31 by penetrating the bracket 32 from the upper surface side of the bracket 32, is screwed into the female threaded hole 34a of the first fastening element 34, while the two second fastening bolts B2 inserted into the second bolt insertion hole 31b are screwed into the two female threaded holes 35a of the second fastening element 35, and further the third fastening bolt B3, which has been inserted into the bracket 32 from the upper surface side of the bracket 32, is screwed into the female threaded hole 31ea of the embedded nut 31e of the leg 31, thereby firmly fastening the leg 31 to the bracket 32. In this fastened state, the bracket 32 is attached to the underside 1d of the tabletop 1. In the fastening state, the first fastening element 34 attached to the first fastening element mounting hole 31c and the second fastening element 35 attached to the second fastening element mounting hole 31d are all covered by the concealing portion 36 of the bracket 32 and cannot be seen from the outside. In addition, because the upper surface 32a of the bracket 32 is attached to the lower surface of the top plate 1, the heads of the fastening bolts B1, B2, and B3 described above are also not visible from the outside.

As shown in Figures 19 to 24, each bracket 32 is provided with a pair of frame attachments 37 for attaching a vertical tabletop support frame 38 extending in the depth direction of the tabletop 1 and a horizontal tabletop support frame 39 extending in the width direction of the tabletop 1. As shown in Figures 19 and 20, the vertical and horizontal tabletop support frames 38, 39 are made of rectangular pipe material, and a rectangular bolt seat Z is installed between both side walls near the ends. The bolt seat Z has a bolt insertion hole Za with the axis j facing diagonally downward, and windows 38b, 39b for inserting bolts are provided in the bottom walls 38a, 39a of the tabletop support frames 38, 39 at the locations where the axis j passes through. The frame mounting portion 37 of the bracket 32 is a rectangular block having a tip wall 37a against which the end faces 38c, 39c of the top plate support frames 38, 39 abut, and a bolt insertion hole 37b is formed in the tip wall 37a to insert the diagonal bolt Bz inserted through the bolt insertion hole Za of the bolt seat Z, and a nut (not shown) into which the diagonal bolt Bz is screwed is held inside. A pressure-receiving protrusion 37c that abuts against the inner surfaces of the bottom walls 38a, 39a of the top plate support frames 38, 39 is integrally formed on the tip wall 37a. This pressure-receiving protrusion 37c is for strongly connecting the top plate support frames 38, 39 to the bracket 32 with the diagonal bolt Bz. That is, when the diagonal bolt Bz with its axis j inclined is screwed into the nut through the bolt seat Z and tightened, the top plate support frames 38, 39 are raised and urged in a direction approaching the tip wall 37a, and the bottom walls 38a, 39a are pressed against the lower surface of the pressure-receiving projection 37c, and the end faces 38c, 39c are pressed against the tip wall 37a while increasing the pressing force, so that the top plate support frames 38, 39 can be firmly connected to the bracket 32 while being positioned. Each bracket 32 is provided with a pair of frame attachment parts 37 with orientations differing by 90°, so that the vertical top plate support frame 38 and the horizontal top plate support frame 39 can be connected to each bracket 32. Each top plate support frame 38, 39 is more securely fixed to the top plate 1 by screwing the intermediate fixing points s to the top plate 1.

<Table with two melamine tops> (Figs. 25 to 32)
The table M2T with two melamine tops is a pair of tops 101 with approximately the same depth dimension, arranged with the opposite ends 101b facing each other, with a through groove 110 formed between the opposite ends 101b of both tops 101, and bottomed grooves 111, 112 parallel to the through groove 110 formed on the upper surface 101c of each top 101. In this respect, it is common to the table S2T with two laminated wood tops described above, but since the specific configuration of the top 101 is different, the parts related to the top 101 are given different reference numerals from those of the table S2T. Other than the parts related to the top 101, the same reference numerals are used for the parts that are the same or correspond to those of the table S2T with two laminated wood tops, and explanations are omitted.

This table M2T differs from the previously described table S2T in the following ways:

This table M2T differs from table S2T, which has two laminated wood tops, in the material and shape of the top plate 101. That is, the top plate 101 of this table M2T is made of a core material with a melamine laminate attached to the surface, and the bottomed grooves 111, 112 formed in each top plate 101 have both left and right ends 111a, 112a closed near both left and right ends 101e of the top plate 101. The both end portions 111b, 112b of the bottomed grooves 111, 112 are configured so that their depth dimensions gradually decrease until they are approximately zero at the extreme ends (both ends 111a, 112a). Specifically, the bottomed grooves 111 and 112 are formed by embedding a groove forming member G having a constant depth dimension at each portion and end caps H that are fitted to both ends of the groove forming member G and form the ends 111b and 112b of the bottomed grooves 111 and 112 in a mounting groove 101f recessed in the upper surface 101c of the top plate 101. The groove forming member G and the end caps H are each made of synthetic resin and are fitted in a state in which a slight relative movement in the longitudinal direction is allowed. That is, the groove forming member G is a channel-shaped member having the same cross-sectional shape at each portion, and the opening width is set to the standard groove width n described above. The end cap H includes a cap body Hb formed so that the bottom wall Ha gradually rises toward the outer end, and a fitting portion Hc formed integrally with the inner end of the cap body Hb and fitted to the outer end surface of the groove forming member G. The groove forming member G and the end caps H are fitted in a state in which a slight relative movement in the longitudinal direction is allowed. Specifically, the groove forming member G and the end cap H are fitted into the mounting groove 101f engraved into the top plate surface f with a slight gap c remaining between the end face of the groove forming member G and the cap body Hb, allowing for dimensional errors and expansion and contraction of the members due to temperature.

In addition, in this table M2T, only a portion of the through groove 110, not the entirety, has the standard groove width n. In other words, the through groove 110 formed between the opposite ends 101b of the table top 101 has a standard groove width portion 110a having a constant standard groove width n, and an enlarged groove width portion 110b that is wider than the standard groove width portion 110a. In this embodiment, the opening p formed by the enlarged groove width portion 110b is left 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, 112 are formed in each top plate 101. Each bottomed groove 111, 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.

<Optional parts used on the table> (Figs. 35 to 58)
Both of the tables S2T and M2T described above have a plurality of parallel grooves m (through grooves 10, 110 and bottomed grooves 11, 12, 111, 112) in the top surface f, and these grooves m can be used to equip various optional components described in the following (1) to (6).

(1) Z-type felt panel (Figures 35 to 40)
The felt panel 4, which is an optional member, is a panel used on the top plate 1, 101 of the above-mentioned table S2T, M2T, made of a single material, and partially includes an easily deformable region 41 that is more easily deformed than other regions. The felt panel 4 has a constant thickness throughout, including the easily deformable region 41, and multiple cut lines 42 are provided in the easily deformable region 41 so as to face in the same direction and not to interfere with each other. Specifically, the felt panel 4 is made of a felt material having a constant thickness, and is substantially rectangular in the initial position (see Figures 35, 37, and 38) in which it is not deformed. The cut lines 42 provided in the easily deformable region 41 are linear and formed to penetrate from one panel surface 4a to the other panel surface 4b. As shown in Figure 39, in the easy-to-deform region 41, multiple parallel cut line rows 43 are formed, each having multiple cut lines 42 intermittently arranged in the longitudinal direction (vertical direction), and the cut lines 42 of adjacent cut line rows 43 are positioned differently in the longitudinal direction so that they are not aligned horizontally.

In more detail, the felt panel 4 is a panel having a plurality of adjacent regions 44, 45 in the left-right direction, and the easily deformable region 41 is a vertically extending band-shaped region having a substantially vertical cut line 42, and is disposed at the adjacent boundary portion of the regions 44, 45. Specifically, the felt panel 4 is divided into an intermediate region 44 and end regions 45 located on both sides of the intermediate region 44 by two parallel easily deformable regions 41 extending vertically, and the overall shape can be changed to a bent posture (see FIG. 36) that is substantially Z-shaped in plan view by deforming the easily deformable region 41. Near the bottom end of the end section 45, a locking protrusion 46 is formed by penetrating a cylindrical felt material, and the bottom end 45a of the end section 45 (the protrusion t4 located below the downward surface s4 of the locking protrusion 46) is inserted into the groove m of either the table S2T or M2T, and the downward surface s4 of the locking protrusion 46 is locked to the top surface f, allowing the felt panel 4 to be placed upright on the top surface f.

The thickness dimension 4c of the felt panel 4 is set to be the same as or slightly larger than the standard groove width n of the groove m of the table S2T, M2T, so that the lower end 45a of the end section 45 constituting the protrusion t4 that protrudes downward from the downward surface s4 of the locking protrusion 46 can be fitted or pressed into the desired groove m (bottomed grooves 11, 12, 111, 112, through grooves 10, 110) and can be installed without rattling on the tabletop surface f without using any auxiliary tools. The protrusion t4 in this embodiment is plate-shaped with a width dimension w4 that corresponds to the width dimension of the groove m.

Figure 35 shows an example in which the felt panel 4 in the initial position is erected in the center of the table S2T using the through groove 10 and used as a desktop panel. In this usage mode, the installation position can be freely changed along the through groove 10. In addition, if the protruding dimension of the projection t4 that protrudes downward from the downward surface s4 of the locking protrusion 46 is set within the depth dimension of the bottomed grooves 11, 12, the felt panel 4 can also be erected using the bottomed grooves 11, 12.

Figure 36 shows an example in which a bent felt panel 4 is erected on the top surface f of a table S2T using two bottomed grooves 12, and used as a side panel. In this case too, the installation position of the felt panel 4 can be changed in the left-right direction by changing the fitting position with respect to both bottomed grooves 12. In addition, the orientation of the middle region 44 can be changed by appropriately selecting the groove m into which the protrusion t4 of the end region 45 fits, allowing for convenient use as a versatile partition.

Here, FIG. 37 is a front view of the felt panel 4 in its initial position, and FIG. 38 is an enlarged side view of the felt panel 4. FIG. 39 is an enlarged front view showing a part of the easily deformable region 41 of the felt panel 4. And FIG. 40 is an enlarged perspective view of the easily deformable region 41 and its vicinity in a state in which the easily deformable region 41 of the felt panel 4 has been deformed.

This felt panel 4 can also be installed in a similar manner on the top surface f of the table M2T by utilizing the through groove 110 and bottomed grooves 111, 112 of the table M2T.

(2) Felt Panel Noren Type (Figures 41 to 44)
The felt panel 5, which is an optional member, is a panel used on the top plate 1, 101 of the above-mentioned table S2T, M2T, made of a single material, and partially includes an easily deformable region 51 that is more easily deformed than other regions. The felt panel 5 has a constant thickness throughout, including the easily deformable region 51, and multiple cut lines 52 are provided in the easily deformable region 51 so as to face in the same direction and not to interfere with each other. Specifically, the felt panel 5 is made of a felt material having a constant thickness, and is substantially rectangular in the initial position (solid lines in Figures 41, 43, and 44) when not deformed. The cut lines 52 provided in the easily deformable region 51 are formed so as to penetrate from one panel surface 5a to the other panel surface 5b, and each cut line 52 extends horizontally.

In more detail, this felt panel 5 has a lower edge 5e with multiple (2) dividing lines 54 that divide the material at intervals in the left-right direction, forming a curtain section 55 with an open lower edge 55a between these dividing lines 54, and an easily deformable region 51 is provided so that the curtain section 55 can be deformed in the thickness direction. In the illustrated example, the easily deformable region 51 is provided over the entire curtain section 55, but the easily deformable region may be provided only on the upper part of the curtain section 55.

This felt panel 5 has a locking protrusion 57 formed by penetrating a cylindrical felt material near the lower end of the end area 56 located on both sides of the curtain portion 55.The lower end 56a of the end area 56 (the protrusion t5 located below the downward surface s5 of the locking protrusion 57) can be inserted into one of the grooves m of the table S2T to lock the downward surface s5 of the locking protrusion 57 to the top surface f, thereby allowing the felt panel 5 to be placed in an upright position on the top surface f.

The thickness dimension 5c of the felt panel 5 is set to be the same as or slightly larger than the standard groove width n of the groove m of the table S2T, so that the lower end 56a of the end section 56 constituting the protrusion t5 that protrudes downward from the downward surface s5 of the locking protrusion 57 can be fitted or pressed into the desired groove m (bottomed grooves 11, 12, 111, 112, through grooves 10, 110), and can be installed without rattling on the tabletop surface f without the use of any auxiliary tools.

In this embodiment, the protrusion t5 is also plate-shaped and has a width w5 that corresponds to the width of the groove m (standard groove width n).

In this embodiment, the lower end of the curtain portion 55 is set at the same height as the lower end of the end region 56, so that not only the lower end 56a of the end region 56 but also the lower end of the curtain portion 55 can be engaged with the groove m for use.

Figure 41 shows an example of using this felt panel 5 on a table S2T with two laminated wood tops. In this case, the lower end 56a (projection t5) of the end section 56 is engaged with the groove m (standard groove width portion 13a and bottomed groove 11 of the partial through groove 13) so that the curtain portion 55 corresponds to the opening p (enlarged groove width portion 13b of the partial through groove 13). According to this mode of use, the curtain portion 55 can be deformed in the thickness direction as shown in Figure 42, so that wiring and the like from under the floor can be smoothly led onto the top surface f with the lid 14 open to open the opening p.

When using this felt panel 5 on the top surface f of the table M2T, it is desirable to install the curtain portion 55 so that it corresponds to the enlarged groove width portion 110b of the through hole 110.

Here, Fig. 43 is a front view of the felt panel 5, and Fig. 44 is an enlarged partial side view of the felt panel 5. Fig. 44 shows the state in which the curtain portion 55 has been deformed in the thickness direction by using imaginary lines.

The acrylic panel 6, which is an optional member, is used on the top plate 1, 101 having grooves m (through grooves 10, 110, bottomed grooves 11, 12, 111, 112) on the upper surface 1c, 101c, and has a downward surface s6 that abuts on the upper surface 1c, 101c of the top plate 1, 101, i.e., the top plate surface f, and is equipped with a protrusion t6 that protrudes downward from the downward surface s6, so that the protrusion t6 can be engaged with the groove m. The protrusion t6 is an elastically deformable thick plate or block-like member, and is configured so that the protrusion t6 can be elastically engaged with the groove m.

The groove m may be the through groove 10, 110 or the bottomed groove 11, 12, 111, 112 described above, and the protrusion t6 has a width dimension w6 slightly larger than the standard groove width n of the through groove 10, 110 and the bottomed groove 11, 12, 111, 112. The width dimension w6 of the protrusion t6 may be the same as the standard groove width n of the groove m, but by setting it slightly larger, the protrusion t6 can be elastically engaged with the corresponding groove m without rattling.

More specifically, the acrylic panel 6 comprises an acrylic panel body 61 and felt legs 62 fitted to the lower end near both ends of the panel body 61. The lower sides of the legs 62 are provided with a downward surface s6 that abuts against the top plate surface f and the aforementioned protrusion t6 that protrudes downward from the downward surface s6. The panel body 61 may be transparent or translucent. Specifically, as shown in FIG. 48, a mounting slit 61a with a width corresponding to the thickness of the leg 62 is formed by opening downward at the lower end side of the panel body 61, and a mounting slit 62a with a width corresponding to the thickness of the panel body 61 is formed in the leg 62. Each leg 62 is attached to the panel body 61 by engaging these mounting slits 61a and 62a.

Figure 45 shows an example in which the acrylic panel 6 is attached to a through groove 10 located in the center of the depth direction of the table S2T and used like a desktop panel, but the acrylic panel 6 can be erected at any suitable position on the tabletop surface f by using other grooves m.

Here, FIG. 46 is a front view of the acrylic panel 6, and FIG. 47 is an enlarged partial side view of the acrylic panel 6. FIG. 48 is an exploded perspective view of the acrylic panel 6.

(4) Lectern (Figs. 49 to 52)
The book stand 7, which is an optional part, is used on the top surface f of the top plate 1, 101 which has a number of grooves m (through grooves 10, 110, bottomed grooves 11, 12, 111, 112) and has a downward surface s7 which abuts the upper surface 1c, 101c of the top plate 1, 101, i.e., the top surface f, and is provided with a protrusion t7 which protrudes downward from the downward surface s7, and is configured so that the protrusion t7 can engage with the groove m.

More specifically, the reading stand 7 comprises a base plate 71 placed on the top surface f, and a standing plate 72 that stands upright from the front edge of the base plate 71 in a backward tilted position. A downward surface s7 that abuts against the top surface f is formed on the underside of the base plate 71, and a protrusion t7 that protrudes downward from the downward surface s7 is vertically attached to the rear edge of the base plate 71. The base plate 71 and the standing plate 72, including the protrusion t7, are made integrally by bending a sheet metal material. A tip-over prevention plate 73 cut and raised from the base plate 71 is provided integrally at the center of the lower end of the standing plate 72.

Figure 49 shows the reading stand 7(x) placed in a positioned state on the top surface f using the bottomed groove 12 of the table S2T. That is, the protrusion t7 of the reading stand 7(x) is inserted into the bottomed groove 12, and the reading stand 7(x) is positioned in the front-to-back direction, but can be freely moved left-to-right along the bottomed groove 12. Because the reading stand 7(x) is made of sheet metal, documents and the like can be freely held on the front surface of the standing board 72 using a magnet or the like.

Figure 49 shows the case where this reading stand 7 (y) is used as a tilt stand for placing devices such as a personal computer, which is different from the initial purpose. In the reading stand 7 (y) installed for the purpose of using it as a tilt stand, the protruding width dimension g7 of the protrusion t7 of the base plate 71 is set to be equal to or less than the standard groove width n of the bottomed groove 12, and the free end 72a side of the standing plate 72 can be positioned on the use end 1a side of the top plate 1, and the protrusion t7 can be inserted into the bottomed groove 12 together with the base plate 71. As a result, the standing plate 72 can be placed on the top plate surface f in a lying state, and the standing plate 72 is in a forward-leaning position relative to the user. Therefore, it is possible to support a personal computer or the like on this standing plate 72 in a forward-leaning position. In this way, the reading stand 7 can also be used as a tilt stand for a personal computer or the like.

Here, Figure 50 is a front view of the reading stand 7, Figure 51 is a side view, and Figure 52 is a bottom view.

(5) Planting box (Figs. 53 to 55)
The planting box 8, which is an optional component, is used on a top plate surface f having a plurality of grooves m (through grooves 10, 110, bottomed grooves 11, 12, 111, 112), and has a downward surface s8 that abuts on the upper surfaces 1c, 101c of the top plates 1, 101, i.e., the top plate surface f, and is provided with a plurality of protrusions t8 that protrude downward from the downward surface s8. The relative positions of the protrusions t8 are set so that a first installation mode (L1) in which each protrusion t8 is engaged with one groove m, and a second installation mode (L2) in which each protrusion is engaged with a different groove can be selectively adopted.

More specifically, the planting box 8 comprises a top plate 81 with an opening window 81a, end plates 82 extending downward from both ends of the top plate 81, and a channel member 83 that is installed between the end plates 82 and cooperates with the end plates 82 and the top plate 81 to form a box-shaped structure. The top plate 81 and both end plates 82 are integrally formed by bending a sheet metal material, and the sheet metal channel member 83 is attached to the top plate 81 and end plates 82 by welding or the like.

The lower end of each end plate 82 is formed with a bent portion 82a that bends inward and a protrusion t8 that hangs down without bending, and the bent portion 82a has a downward surface s8 that abuts against the top plate surface f. The protrusion t8 protrudes downward from this downward surface s8. The width dimension w8 of each protrusion t8 is set to be equal to or less than the width of the groove m of the table S2T, M2T (standard groove width n of a through groove and a bottomed groove), so that the first installation mode (L1) described above can be adopted. In addition, the separation distance between the two protrusions t2 is set to correspond to the separation distance between specific grooves m of the tables S2T, M2T, so that the second installation mode (L2) described above can also be adopted. In this embodiment, the distance d1 between the central groove m (through groove 10, 110) of the table S2T, M2T and the use end 1a, 101a is set equal to the distance d2 between the second bottomed grooves 12, 112. This planting box 8 can be used not only as a tray for displaying natural or artificial plants, but also as a storage container for storing shared items, etc.

Figure 53 shows an example of the state in which the planting box 8 (x) is placed on the top surface f of the table S2T, M2T in the first installation mode (L1). In this state, both protrusions t8 are inserted into one groove m (through groove or bottomed groove) and positioned, and the downward surface s8 is supported in contact with the top surface f.

Figure 53 also shows an example of the state in which the planting box 8 (y) is placed on the top surface f of the table S2T, M2T in the second installation mode (L2). In this mode, one of the protrusions t8 of the planting box 8 (y) is engaged with the groove m (through groove 10, 110) of the table S2T, M2T, and the other protrusion t8 is engaged with the use end 1a, 101a of the table S2T, M2T to position it.

Figure 53 also shows another example of the state in which the planting box 8 (z) is placed on the top surface f of the table S2T, M2T in the second installation mode (L2). In this mode, the planting box 8 (z) is positioned by engaging one protrusion t8 with the groove m (bottomed groove 12) of one of the top plates of the table S2T, M2T, and engaging the other protrusion t8 with the groove m (bottomed groove 12) of the other top plate of the table.

Here, Figure 54 is a front view of the planting box 8, and Figure 55 is an enlarged side view of the same.

(6) Shelf (Figures 56 to 58)
The shelf 9, which is an optional member, is used on the top surface f of the top plate 1, 101 having a plurality of grooves m (through grooves 10, 110, bottomed grooves 11, 12, 111, 112), and has a downward surface s9 that abuts against the upper surface 1c, 101c of the top plate 1, 101, and is equipped with a plurality of protrusions t9 that protrude downward from the downward surface s9. The relative positions of the protrusions t9 are set so as to selectively take a first installation mode (L1) in which each protrusion t9 is engaged with one groove m, and a second installation mode (not shown) in which each protrusion t9 is engaged with a different groove m.

More specifically, the shelf 9 comprises a top plate 91, end plates 92 extending downward from both ends of the top plate 91, and a reinforcing channel member 93 installed between the end plates 92. The top plate 91 and both end plates 92 are integrally formed by bending a sheet metal material, and the sheet metal channel member 93 is attached to the top plate 91 and end plates 92 by welding or the like.

The lower ends of both end plates 92 are formed with a bent portion 92a that bends inward and a protrusion t9 that hangs down without bending, and the bent portion 92a has a downward surface s9 that abuts against the top plate surface f. The protrusion t9 protrudes downward beyond this downward surface s9.

The shelf 9 is intended to use the top surface f of the desks S2T and M2T more efficiently, and can be placed on the top surface f in a manner similar to the planting box 8 described above. Furthermore, the shelf 9 can also be placed above the opening p, as shown in FIG. 56.

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

<Functions and Effects of the Table According to the Present Embodiment>
With tables S2T and M2T of this configuration, multiple grooves m (through grooves 10, 110 and bottomed grooves 11, 12, 111, 112) are exposed in parallel on the top surface f, and these grooves m can be used appropriately to position and hold the optional members 4 to 9 and the like described above without using any tools. Therefore, despite its simple configuration, it is possible to arrange a variety of options, making it easy to use.

The through grooves 10, 110 formed between the top plates 1, 101 not only serve as wiring holes that connect the bottom surfaces 1d, 101d and top surfaces 1c, 101c of the top plates 1, 101, but can also be used as gaps to pass through posts for supporting desktop panels erected on the floor. In particular, the through grooves 10, 110 are formed continuously from one end to the other in the left-right direction of the top plates 1, 101, so that the location of use can be freely selected, making them easy to use.

Furthermore, the bottomed grooves 11, 12, 111, 112 are not limited to holding and positioning the optional components 4 to 9 as described above, but can also be used, for example, to prop up a smartphone SP or a tablet terminal (not shown). In particular, in this embodiment, multiple bottomed grooves 11, 12, 111, 112 are provided in parallel on each tabletop 1, 101, so that the location of use can be changed not only in the left-right direction but also in the depth direction, allowing for a variety of uses.

The through grooves 10, 110 may have a constant standard groove width n as a whole, as in the case of the table S2T with two laminated wood tops, or may have the standard groove width n only in part, as in the case of the table M2T with two melamine tops. The through groove 110 in the table M2T with two melamine tops has a standard groove width portion 110a having the standard groove width n and an expanded groove width portion 110b that is wider than the standard groove width portion 110a, and the existence of the expanded groove width portion 110b forms an opening p that connects the upper and lower surfaces of the top plate 101. Therefore, it is possible to use the opening p to insert not only wiring, but also relatively bulky outlets and connectors, or supports erected on the floor surface.

In addition, the standard groove width n of the through grooves 10, 110 and the standard groove width n of the bottomed grooves 11, 12, 111, 112 are unified, which not only improves the appearance but also increases the probability that the through grooves 10, 110 and the bottomed grooves 11, 12, 111, 112 can be used freely without distinguishing between them when holding or positioning various options 4 to 9, improving convenience.

Furthermore, in the table S2T with two laminated wood tops, both left and right ends of the bottomed grooves 11, 12 reach both left and right ends of the top 1 and are open, so dust that has accumulated in the bottomed grooves 11, 12 can be easily swept out to the side. On the other hand, in the table M2T with two melamine tops, both left and right ends 111a, 112a of the bottomed grooves 111, 112 are blocked near both left and right ends 101e of the top 101, but the depths of both ends 111a, 112a of the blocked bottomed grooves 111, 112 gradually decrease until they are nearly zero at the extreme ends (both ends 111a, 112a), so foreign matter in the bottomed grooves 111, 112 can be easily discharged.

In addition, the table M2T, which has a two-piece melamine top and a multi-layered structure with melamine decorative panels attached to the surface of the core material, has bottomed grooves 111, 112 closed near the ends of the top 101, which solves the problem 2 mentioned above. In other words, with this configuration, both the left and right ends 101e of the top 2 can be completely covered with melamine decorative panels, and there is no problem with the end processing of the top 101 being cumbersome.

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

For example, the material of the tabletop is not limited to laminated wood or melamine laminated board. In other words, the present invention can be applied to a tabletop made of laminated wood as long as both ends of the bottomed groove are closed near both ends of the tabletop.

The bottomed grooves may be directly engraved on the top surface of the tabletop, but if they are as shown in the figure, they can be applied to a multi-layered two-sheet melamine table M2T without any problems. In other words, if the bottomed grooves 111, 112 are formed by embedding a groove forming member G having a certain depth dimension in each part and end caps H that are fitted to both ends of the groove forming member G and form the ends 111, 112 of the bottomed grooves in the top surface of the tabletop 101, it is possible to form bottomed grooves 111, 112 that look good and are highly durable. Moreover, when adopting such a structure, if the groove forming member G and the end caps H are fitted together in a state where some relative movement in the longitudinal direction is allowed, dimensional errors that occur between the groove forming member G and the end caps H and the tabletop 101 and relative dimensional changes due to temperature changes can be absorbed.

Various modifications may be made without departing from the spirit of the present invention.
