Description

Technical Field

[0001] The present invention relates to a table suitably used in offices and the like.

Background Art

[0002] Conventionally, various tables have been used in which a plurality of use ends are set at the periphery of a tabletop, a plurality of people can use it simultaneously, and the tabletop has an opening at the center (see, for example, Patent Document 1).

[0003] In such a table, it is conceivable to attach an optional member such as a monitor arm via a clamp around the opening. Such a clamp is often attached to the part of the opening closest to the use end.

[0004] However, in such a mode, since the clamp is arranged at a part close to the use end, the effective depth dimension of the tabletop available to the user sitting at the use end becomes small. In particular, when arranging a power outlet in front of (on the use end side) the clamp, the position of the power outlet is restricted by the presence of the clamp, making it difficult to secure a large effective depth dimension.

Mode for Carrying Out the Invention

[0020] An embodiment of the present invention will be described with reference to the drawings.

[0021] The table T according to the present embodiment is formed by supporting a top plate 1 that can be used from the surroundings by a plurality of loop legs 2. That is, the table T of the present embodiment includes a top plate 1 and a plurality, specifically three loop legs 2 that support the top plate 1 from below, as shown in FIGS. 1, 2, 4 to 6, 8, and 10.

[0022] As shown in Figures 1 and 3 to 8, the tabletop 1 has a plurality of usable ends 1a provided at intervals in the circumferential direction around its periphery, three usable ends 1a arranged at equal angular intervals in the circumferential direction and forming a substantially straight line in plan view, and a plurality of connecting ends 1b connecting the ends of these usable ends 1a, three connecting ends 1b forming a convex curve in this embodiment. More specifically, the tabletop 1 is made up of three tabletop elements 11, each with a usable end 1a set in the center in the width direction, arranged at equal angular intervals in the circumferential direction, specifically at 120-degree intervals. In addition, a reinforcing member 12 extending along the usable end 1a is provided on the underside of the tabletop 1 near each usable end 1a.

[0023] As shown in Figures 1 and 3 to 11, an opening 1c is provided in the center of the top plate 1, and a clamp mounting area R is provided around the opening 1c. The clamp mounting area R is positioned offset to the left and right with respect to a virtual line L connecting the center of the usable end 1a and the center of the opening 1c in a plan view. More specifically, each top plate element 11 has a roughly V-shaped notch 11a on the side opposite the usable end in a plan view, and a roughly triangular opening 1c is formed by connecting the notches 11a of the three top plate elements 11. Then, a clamp mounting area R corresponding to each usable end 1a is set around the opening 1c. To elaborate further, each opening 1c has a straight section 1c1 that forms a 60-degree angle with each corresponding usable end 1a of the top plate 1, and the clamp mounting area R is positioned outside the straight section 1c1. This clamp mounting area R is shifted to the left of the center of the opening 1c as viewed from a user seated at the usable end 1a, and is located to the left and further back than the position closest to the usable end 1a and facing the user in the opening 1c. An electrical outlet 13 is positioned close to the opening 1c between the opening 1c and the usable end 1a of the tabletop 1. The system is configured so that an optional monitor arm 4 can be attached to this clamp mounting area R via a clamp 3.

[0024] In this embodiment, as shown in Figure 12, the clamp 3 comprises an upper member 31 attached to the upper surface of the top plate 1, a lower member 32 facing the lower surface of the top plate 1, a connecting member 33 connecting the lower member 32 and the upper member 31 at a position where the top plate 1 is not present, an adjustment screw 34 screwed into the lower member 32 so as to be able to move up and down, and a pressing plate 35 that is detachably attached to the upper end of the adjustment screw 34 and pressed against the lower surface of the top plate 1. The upper member 31, lower member 32 and connecting member 33 of the clamp 3 are integrally molded products made from a common sheet metal material, and two adjustment screws 34 are detachably screwed into the lower member 32. A connecting shaft 341 is formed at the upper end of each adjustment screw 34, and these connecting shafts 341 can be rotatably and detachably engaged with a connecting hole 35a provided in the pressing plate 35. In other words, this clamp 3 is designed so that after engaging only the upper member 31, lower member 32, and connecting member 33 with the opening edge of the opening 1c of the top plate 1, the aforementioned adjustment screw 34 and retaining plate 35 are attached and the adjustment screw 34 is tightened, thereby pressing the retaining plate 35 against the underside of the top plate 1. The upper member 31 of the clamp 3 in this embodiment is substantially circular in shape, and the monitor arm 4 is rotatably erected from its center.

[0025] The monitor arm 4 can be operated between a personal use position (P) in which the monitor 5 faces a single user end 1a and a shared use position (Q) in which the monitor can be shared by users of adjacent user ends 1a. That is, as shown in Figure 12, the monitor arm 4 comprises a support column 41 that rises from the center of the upper member 31 of the clamp 3, and a monitor support portion 42 provided near the middle of the support column 41. The support column 41 has a crank-shaped lower support column 411 whose lower end is supported by the upper member 31 of the clamp 3, and an upper support column 412 that is fitted onto the lower support column 411, is slidable vertically relative to the lower support column 411, and is rotatable around the axis of the lower support column 411, and has a monitor support portion 42 provided in its middle. On the other hand, the monitor support portion 42 has a plate-shaped monitor support bracket 421 that can be screwed to the back surface of the monitor 5, and a connecting portion 422 that connects the monitor support bracket 421 and the upper support column 412. This connection section 422 supports the monitor 5 in a manner that allows the angle at which the monitor 5 makes contact with the top surface (the upper surface of the top surface 1) to be changed. By rotating the support column 41 together with the monitor 5, the monitor 5 can be operated between a personal use position (P) and a shared use position (Q). In Figures 6, 7, and 9, only one monitor 5 is attached via the monitor arm 4, and that monitor 5 is in the personal use position (P). In Figure 13, three monitors 5 are attached via the monitor arm 4, with one of the three monitors 5 in the shared use position (Q) and the remaining two in the personal use position (P). As described above, the monitor arm 4 can be attached to the top surface 1 via the clamp 3, and the top surface 1 is supported from below by three loop legs 2.

[0026] Each loop leg 2 comprises a leg base 6 positioned on the floor, an inner leg column 7 erected at the inner end of the leg base 6 to support the vicinity of the center of the tabletop 1, and an outer leg column 8 erected at the outer end of the leg base 6 to support the vicinity of the connection end 1b of the tabletop 1, with a space S formed between the inner leg column 7 and the outer leg column 8. Furthermore, each loop leg 2 is positioned directly below the boundary between the tabletop elements 11. That is, the three loop legs 2 are positioned at equal angular intervals in the circumferential direction, specifically at 120-degree intervals. More specifically, each loop leg 2 has its inner leg column 7 bundled together by a common bracket, i.e., a central bracket 9, and fixed to the vicinity of the center of the tabletop 1, while each outer leg column 8 is fixed to the vicinity of the connection end 1b of the tabletop 1 via individual brackets 81, more specifically, inset a certain distance inward from the connection end 1b of the tabletop 1 to the underside of the tabletop 1.

[0027] The central bracket 9 is attached to the lower surface of the central part of the top plate 1 and integrally comprises an outer member 91 having an opening 91a in the center and an inner member 92 attached below the outer member 91 that closes a part of the opening 91a of the outer member 91. That is, the outer member 91 and the inner member 92 are connected and integrated, for example, by welding. The outer member 91 is provided with an opening 91a that corresponds to the shape of the opening 1c formed in the center of the top plate 1, and notches 91b are provided at three locations on the opening edge of the opening 91a, into which the retaining plate 35 of the clamp 3 can be placed. On the other hand, the inner member 92 is a plate that is roughly triangular in shape and has notches 92a in the middle of each side. A slit-shaped gap SS is formed between the notches 92a and the opening edge of the opening 1c of the top plate 1, through which the clamp 3 can be inserted. The upper ends of the inner leg columns 7 of the three loop legs 2 are bundled together and fixed to the inner member 92 by means of welding or other means, and the central part of the tabletop 1 is supported from below by these inner leg columns 7 of the loop legs 2. In this embodiment, the leg base 6 is formed by joining an inner first leg base element 61 and an outer second leg base element 62. The first leg base element 61 and the inner leg column 7 are integrally constructed using a common pipe material. Similarly, the second leg base element 62 and the outer leg column 8 are integrally constructed using a common pipe material. Adjusters 63 are provided at both ends of the leg base 6 in the longitudinal direction. No members are placed between the leg base 6 and the tabletop 1, in other words, between the inner leg column 7 and the outer leg column 8, allowing the user's legs, etc., to move freely within the space S formed between them.

Figure 5 is a bottom perspective view thereof. Figure 6 is a top perspective view showing the state in which the monitor arm 4 is attached to the table T according to this embodiment via a clamp 3 and the monitor 5 is supported by the monitor arm 4. Figure 7 is a top view thereof. Figure 8 is a bottom view thereof. Figure 9 is an enlarged view of the main part in Figure 7. Figure 10 is an enlarged view of the main part in Figure 8. In Figures 6, 7 and 9, the monitor is in the individual use position (P). Figure 11 is a cross-sectional view along line AA in Figure 9. Figure 12 is a diagram showing the clamp 3 and monitor arm 4, where (a) is a perspective view, (b) is a plan view, and (c) is a front view. Figure 13 is a plan view showing three monitor arms 4 attached with monitors 5 each supporting a monitor 5, with one of the monitors 5 in a shared use position (Q) that can be shared by users at adjacent use ends 1a.

[0030] As described above, according to the configuration of this embodiment, the clamp mounting area R is positioned to the left with respect to the imaginary line L connecting the center of the usable end 1a and the center of the opening 1c in a plan view. Therefore, compared to the configuration in which the clamp is positioned at a location corresponding to the center of the usable end, the clamp 3 is positioned further away from the usable end 1a. Consequently, the effective depth dimension of the tabletop surface usable by a user seated at the usable end 1a can be increased. In particular, since the outlet 13 can be positioned close to the opening 1c between the opening 1c and the usable end 1a, it is possible to suppress the reduction in the effective depth dimension of the tabletop surface usable by the user even when the outlet 13 is installed.

[0031] Furthermore, since the tabletop 1 has a shape that includes three usable ends 1a that are substantially straight in plan view, and three connecting ends 1b that form a convex curve connecting the ends of these usable ends 1a, it is possible for three people to easily access the connecting ends 1b while seated, thereby promoting communication among users.

[0032] In addition, the tabletop 1 has three usable ends 1a that are roughly straight and arranged at equal angular intervals in the circumferential direction, and a clamp mounting area R corresponding to each usable end 1a is set around the opening 1c. Therefore, when used by three people, compared to a circular tabletop, if the effective area of ​​the tabletop surface usable by each person and the dimensions of the usable ends are the same, unlike a circular tabletop where the usable ends are arc-shaped and the center of the arc protrudes towards the person sitting, the center of each roughly straight usable end 1a does not protrude towards the person sitting, so the opening 1c provided in the center of the tabletop 1 and each usable end 1a can be brought closer together. Furthermore, as mentioned above, the clamp mounting area R is set to the left of the imaginary line L connecting the center of the usable end 1a and the center of the opening 1c in a plan view, so that the effective depth dimension of the tabletop surface usable by the user can be secured.

[0033] Furthermore, since the monitor arm 4 can be operated between a personal use position (P) in which the monitor 5 faces a single user end 1a and a shared use position (Q) in which the monitor 5 can be shared by users of adjacent user ends 1a, it can accommodate a variety of usage scenarios.

[0034] In addition, since the clamp 3 comprises an upper member 31 attached to the upper surface of the top plate 1, a lower member 32 facing the lower surface of the top plate 1, a connecting member 33 connecting the lower member 31 and the upper member 32 at a position where the top plate 1 is not present, an adjustment screw 34 screwed into the lower member 32 so as to be able to move up and down, and a pressing plate 35 that is detachably attached to the upper end of the adjustment screw 34 and pressed against the lower surface of the top plate 1, as described above, after engaging only the upper member 31, the lower member 32 and the connecting member 33 with the opening edge of the opening 1c of the top plate 1, the aforementioned adjustment screw 34 and pressing plate 35 can be attached and the adjustment screw 34 tightened to press the pressing plate 35 against the lower surface of the top plate 1.

[0035] However, the present invention is not limited to the embodiments described above.

[0036] For example, the plan view shape of the tabletop is not limited to a triangle, but may be a circle, a square, or the like. The number of usable ends is not limited to three, and it is not necessary to provide connecting ends that form a convex curve to connect the ends of the usable ends. Furthermore, the shape of the usable ends is not limited to a straight line, but may be a convex curve that protrudes toward the user, or conversely, a concave curve with a recessed central part facing the user. As an example, consider a table TT as shown in Figure 14 in plan view. The tabletop 1 of this table TT is rectangular (square) in plan view, with each side being a usable end 1a, and an opening 1c is provided in the center that forms a square with each side inclined at 45 degrees relative to each usable end 1a. A clamp mounting area RR is provided around this opening 1c, and optional members such as monitor arms can be attached to the clamp mounting area RR via a clamp (not shown). Furthermore, the clamp mounting area RR is provided offset to the left (for example, to the left) with respect to a virtual line LL connecting the center of the usable end 1a and the center of the opening 1c in plan view. Furthermore, an electrical outlet 13 is positioned close to the opening 1c between the opening 1c of the tabletop 1 and the usable end 1a. Even with this configuration, since the clamp mounting area RR is offset to the left with respect to the imaginary line L connecting the center of the usable end 1a and the center of the opening 1c in a plan view, the clamp is positioned further away from the usable end 1a compared to a configuration in which the clamp is positioned at a location corresponding to the center of the usable end 1a. This allows for the most important effect of the present invention, namely, the ability to increase the effective depth dimension of the tabletop surface usable by a user seated at the usable end 1a.

[0037] Furthermore, the optional components are not limited to monitor arms; they can be any components that can be attached via a clamp.

[0038] Furthermore, a loop leg in which the leg base, inner leg column, and outer leg column are integrally constructed using a common pipe material, or other leg shapes such as plate-shaped legs may be adopted.

[0039] In addition, the location of the clamp mounting area can be set arbitrarily, as long as it is offset to the left or right with respect to the imaginary line connecting the center of the end to be used and the center of the opening in a plan view, and is further back than the point where the opening is closest to the end to be used, i.e., on the side furthest from the end to be used. The shape of the opening can also be any shape as long as the clamp mounting area can be set at the location described above. Furthermore, although a straight section is provided in the opening in the embodiment described above, a substantially straight section, i.e., a slightly curved straight section, may also be provided in the opening.

[0040] Furthermore, it is not necessary to install an electrical outlet on the tabletop, and any type of clamp configuration can be used.

[0041] Furthermore, various modifications are permitted as long as they do not impair the spirit of the present invention. [Explanation of Symbols]
