[0001] The present invention relates to a desk and a desk system suitable for use in dealing rooms, general offices, and the like. [Background technology]

[0002] Recently, electronic devices such as PCs and displays mounted on this type of desk tend to be connected by many cords, so inside the desk there is provided a wiring storage space to efficiently store these cords, outlets, etc.

[0003] Such a wiring storage space is often provided along the underside of the tabletop, and may also be formed inside the legs that support the tabletop (see Patent Document 1).

[0004] However, conventional wiring storage spaces cannot be opened to the outer edges of the desks, so when multiple desks are arranged with their outer edges butted together, the cords end up being exposed to the outside at the butted edges.

[0005] This not only impairs the appearance, but also poses the problem that the exposed parts can easily get in the way of workers. [Prior art documents] [Patent documents]

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0018] 1 to 5 show a desk system A according to one embodiment of the present invention, and FIGS. 6 to 17 show a desk B that constitutes this desk system A. FIG.

[0019] In this embodiment, desk system A is formed by arranging two desks B (hereinafter, one desk may be designated as "B1" and the other desk as "B2") in a horizontal row.

[0020] The desk B comprises a desk body C having outward openings E on both the left and right end faces D, a wiring storage space G provided in the desk body C that can be opened outward through the openings E, and an exterior lid body 14 that can be opened and closed on the opening E. As shown in Figure 5, the desk B is configured so that the side end face D of another desk B having the same structure can be placed against the side end face D when the opening E is open.

[0021] More specifically, as shown in Figure 6, this desk B comprises a desk body C having a pair of left and right leg structures 1 installed on an existing floor surface J, a tabletop support frame 2 supported by the leg structures 1, and a tabletop 3 supported by the left and right leg structures 1 via the tabletop support frames 2.

[0022] As shown in Figures 5, 6, 7, etc., the leg structure 1 includes a front leg 11, a rear leg 12, and a housing 13 that holds the legs 11, 12 in an upright position with a certain distance between them, and the outer surface 13a of the housing 13 forms a side end surface D of the desk body C. Therefore, the outer surface 13a of the housing 13 (the side end surface D of the desk body C) is positioned slightly outwardly relative to the side surface 3a of the tabletop 3, and an opening E is formed in the outer surface 13a. In other words, the desk B is configured such that the left and right side ends of the tabletop 3 are supported by a pair of front and rear legs 11, 12, and each wiring storage space G is formed in each housing 13, positioned between the adjacent front and rear legs 11, 12.

[0023] More specifically, the left and right leg structures 1 each include a front leg 11, a rear leg 12, and a housing 13 that holds the front and rear legs 11, 12 in an upright position.

[0024] As shown in Figures 7 and 8, the desk body C of this desk B is of a lifting type, configured so that the tabletop 3 can be raised and lowered by extending and contracting the legs 11, 12. That is, this desk body C is equipped with legs 11, 12 that can be extended and contracted in the vertical direction by electric power, and the tabletop 3 is raised and lowered by the extension and contraction movement of the legs 11, 12. The legs 11, 12 are disposed within the front and rear ends of each housing 13, respectively. Each leg 11, 12 is configured by combining a lower cylindrical section 11a, 12a, a middle cylindrical section 11b, 12b, and an upper cylindrical section 11c, 12c in a telescopic manner, and is configured so that these cylindrical sections 11a, 12a, 11b, 12b, 11c, 12c are extended and retracted by an internal electric actuator (not shown) (for example, an "Electric Lifting Device" manufactured by LINAC Corporation). As shown in Figures 6, 12, and 13, each leg has an upper-end lifting section 11d, 12d at its upper end. The leg 11, 12 itself has a conventional structure, so a detailed description will be omitted. A control lever 37 for operating the extension and retraction of the leg 11, 12 is attached to the underside 3a of the tabletop 3. Reference numeral 36 denotes a control box for supplying power to the legs 11, 12 according to the manner of operation applied to the control lever 37, and is attached within the connecting member 22 of the tabletop support frame 2 as shown in Figures 9 and 12, etc.

[0025] The housing 13 that holds the front and rear legs 11, 12 is made of, for example, sheet metal, and as shown in Figures 15 to 17, includes an outer wall member 13a, an upper reinforcing member 13b, a middle partition member 13c, and an inner wall member 13d.

[0026] The outer wall member 13a comprises an outer plate 3a1, a front plate 3a3 extending inward from the front edge of the outer plate 3a1, and a rear plate 3a4 extending inward from the rear edge of the outer plate 3a1, and an opening 3a2 corresponding to the outward opening E mentioned above is formed in the lower half of the outer plate 3a1.

[0027] The upper reinforcing member 13b is a channel-shaped member extending in the front-rear direction, and is rigidly connected to the inside corner between the outer plate 3a1 and the upper plate 3a5 of the exterior wall member 13a by welding or the like. The upper reinforcing member 13b is provided with female threaded holes w for fastening a connecting box or the like (not shown) with screws 3b1, and female threaded holes w for screwing in a coat duct mounting bracket 3b2 for fastening the lower end of a cord duct 35 (described later).

[0028] The intermediate partition member 13c includes a front partition plate 3c1 that forms a space for accommodating the legs 11 between itself and the front plate 3a3 of the outer wall member 13a, and a rear partition plate 3c3 that forms a space for accommodating the legs 12 between itself and the rear plate 3a4 of the outer wall member 13a, and is rigidly connected to the outer wall member 13a by welding or the like. As shown in FIG. 14 , nuts t are embedded in the lower parts of the front partition plate 3c1 and the rear partition plate 3c3 to fasten with screws S the mounting portion 14a of the exterior cover 14 that is attached to the opening E (opening 3a2 of the outer plate 3a1). When the exterior cover 14 is attached to the opening E, the outer surface of the exterior cover 14 is substantially flush with the side end surface D of the desk B, and the opening E is completely covered by the exterior cover 14.

[0029] 16 and 17, bases 3c2 and 3c4 for supporting the lower ends of the legs 11 and 12 held in the housing 13 are fixed by welding or the like to the lower ends of the intermediate partition member 13c and the outer wall member 13a. The bases 3c2 and 3c4 are horizontal plates with an adjuster p in the center, and the legs 11 and 12 are fixed to the housing 13 by threading screws r that are passed through screw insertion holes q of the bases 3c2 and 3c4 from below into the lower ends of the legs 11 and 12.

[0030] As shown in Fig. 16, a front inner plate 3d1 is attached between the inner ends of the front plate 3a3 of the outer wall member 13a and the front partition plate 3c1 of the intermediate partition member 13c, and a rear inner plate 3d2 is attached between the inner ends of the rear plate 3a4 of the outer wall member 13a and the rear partition plate 3c3 of the intermediate partition member 13c, so that the lower cylindrical portions 11a and 12a of the legs 11 and 12 are surrounded from the periphery. A wiring storage space G is formed between the front partition plate 3c1 and the rear partition plate 3c3 of the intermediate partition member 13c, and an inward opening F is formed between the inner ends of the front partition plate 3c1 and the rear partition plate 3c3, opening the wiring storage space G to the space below the top plate 3. This opening F is also openably covered by an inner cover 15, as shown in Figs. 15, 17, etc. As shown in Figure 15, the base end of this inner lid body 15 is hinged to the rear plate 3a4 of the exterior member 13a via a hinge portion 15a, and the rotating end is provided with a magnetic catch 15b for holding the inner lid body 15 in the closed position.

[0031] The housing 13 described above has a shape that is open downward, and the wiring storage space G formed inside is provided in a position that directly faces the existing floor surface J. The opening E (opening 3a2 in the outer panel) that opens this wiring storage space G outward also has a cutout shape that is open downward.

[0032] A tabletop 3 is provided on the leg structure 1 having such a configuration via a tabletop support frame 2.

[0033] As shown in Figures 9 and 12, the tabletop support frame 2 comprises a tabletop holder 21 attached to the upper lifting sections 11d, 12d of the front and rear legs 11, 12, a front connecting member 22 connecting the front legs 11 of the left and right pair of leg structures 1, a rear connecting member 23 connecting the rear legs 12, an option mounting frame 24 provided on the rear connecting member 23, and a wiring holder 25 installed between the left and right tabletop holders 21.

[0034] As shown in FIGS. 1, 2, 3, and 6 to 9, the tabletop support 21 is made of sheet metal and extends in the front-rear direction, and supports the tabletop 3 on its upper surface via a flat slider 32a so that the tabletop 3 can slide back and forth. A slide connecting mechanism 32 is provided between the tabletop support 21 and the tabletop 3 to guide the tabletop 3 slidably between an advanced position and a retracted position. As shown in FIGS. 9, 13, and 14, the slide connecting mechanism 32 includes a slit 32b that extends front-rear and is formed in the tabletop support 21, and a slide pin 32c that passes through the slit 32b so that the tabletop 3 can slide back and forth. The slide pin 32b is fixed to the tabletop 3. The length of the slit 32b is set so that the tabletop 3 opens the upper surface of the cable holder 25 in the advanced position (not shown) and substantially closes the upper surface of the cable holder 25 except for a slit 3d, which will be described later, in the retracted position (see FIG. 12, etc.). A locking mechanism 33 (described later) is provided between the top plate 3 and the top plate support 21 to position the top plate 3 at the forward or backward position.

[0035] 2, 3, 6, and 9, the front connecting member 22 is made of a channel material that is open downward, and is installed between the front legs 11 with both ends supported by the upper lifting portions 11d of the front legs 11. The aforementioned control box 36 is housed within this connecting member 22, and cords (not shown) connected to this control box 36 are also inserted through it.

[0036] As shown in Figures 2, 3, and 9, the rear connecting member 23 is made of a channel material that is open downward, and is installed between the rear legs 12 with both ends supported by the upper lifting portions 21d of the rear legs 12.

[0037] 1 to 5 and 12, the option mounting frame 24 is made of an extruded material such as aluminum alloy, and has multiple dovetail grooves formed on the top surface. The option mounting fixture 24a shown in Fig. 12 is for mounting a display, for example, and is attached to the option mounting frame 24 so that its fixed position can be changed in the left-right direction.

[0038] As shown in Figures 2, 3, and 6 to 9, the cable receptacle 25 is a box-like structure that is open upward and forward and extends laterally, and is installed between the left and right top plate receptacles 21. As shown in Figure 12, the cable receptacle 25 is made of sheet metal and has a bottom wall 25c, side walls 25d, and a back wall 25e that are integral with each other, and notches 25a through which cords can be inserted are formed at the boundaries between the bottom wall 25c and each side wall 25d. A front-opening front cover 25b is provided on the front of the cable receptacle 25, the lower edge of which is hinged to the bottom wall 25c.

[0039] The tabletop 3 is disposed on the tabletop support frame 2 configured as described above. The tabletop 3 has a tabletop main body 31 that is rectangular in plan view, and as shown in Fig. 12, a plurality of sliders 32a provided on the underside of the tabletop main body 31 are in sliding contact with the upper surface of the tabletop support 21. In other words, the tabletop 3 can slide between the forward position and the backward position described above by the sliding action of the sliders 32. The sliders 32a are flat and may be fixed to either the underside of the tabletop 3 or the upper surface of the tabletop support 21.

[0040] At the usable end (front end) of the tabletop 3, an unlocking lever 33c of the locking mechanism 33 is disposed adjacent to a control lever 37 for extending and retracting the legs 11, 12 to raise and lower the tabletop 3. The locking mechanism 33 locks the tabletop 3 in the retracted position and can release the locked state by operating the unlocking lever 33c. Specifically, as shown in Figures 9, 13, 14, etc., the locking mechanism 33 comprises an engaging recess 33a formed on the inner edge of the tabletop support 21, an engaging protrusion 33b that is retractable into and retractable from the tabletop 3 and elastically engages with the engaging recess 33a at a position facing the engaging recess 33a, and a power transmission cable 33d that transmits an operating force applied to the unlocking lever 33c to the engaging protrusion 33b, thereby disengaging the engaging protrusion 33b from the engaging recess 33a.

[0041] Here, reference numeral 35 denotes a cord duct that protects and guides cords. The cord duct 35 is a flexible, cylindrical duct that is a typical one that can deform in response to the elevation of the tabletop 3, as shown in Figures 7 and 8. In this embodiment, the lower end of the cord duct 35 is fixed within the cable insertion space G, and the upper end is fixed near the end of the cable holder 25 on the tabletop support frame 2.

[0042] In the desk B configured as described above, a wiring storage space G is formed within the housing 13 of the leg structure 1 supporting the tabletop 3. This wiring storage space G is connected to the vicinity of the underside 3b of the tabletop 3 through the cord duct 35. Therefore, for example, signal transmission cords, power supply cords, and the like extending from the existing floor surface J can be housed within the wiring storage space G and can be guided through the cord duct 35 to the vicinity of the end of the cable receptacle 25 directly below the tabletop 3. The cords extending from the upper end of the cord duct 35 can be guided into the cable receptacle 25 by passing through the notch 25a. As shown in FIG. 12 , the cords in the cable receptacle 25 can also be guided to the upper surface 3e of the tabletop 3 through the gap 3d formed between the rear end surface 3c of the tabletop 3 and the connecting member 23. The above description is an example, and various cords, outlets, and the like can be housed and guided appropriately within the desk body C of the desk B.

[0043] On the left and right side end faces D of the desk B, outward openings E are formed that open the wiring storage space G outward, but when the desk B is used alone, these openings E can be closed with an exterior cover 14 to prevent the appearance from being marred and the cords in the wiring storage space G from protruding to the outside.

[0044] When constructing desk system A by butting the side end face D of a specific desk B1 against the side end face D of another desk B2 of the same structure, the exterior covers 14 of both desks B1 and B2 are removed, as shown in Figures 4 and 5. In this specification, "desks of the same structure" means desks that have the same basic structure, and the presence or absence of accessories and options is not taken into consideration. Incidentally, this embodiment illustrates a case in which the cord duct 35 is attached only to the leg structure 1 on the butted side end face D side, but the cord duct 35 may also be provided on the leg structure 1 on the open side end face D side.

[0045] In this embodiment, the exterior cover 14 can be attached or detached with the interior cover 15 open. That is, as shown in Fig. 15, when the interior cover 15 is opened inward, the wiring storage space G and the inner surface of the exterior cover 14 can be seen. Therefore, the exterior cover 14 can be removed from the opening E by unscrewing the screws s that fasten the mounting portions 14a of the exterior cover 14 to the housing 13 from the lower leg space side.

[0046] When two desks B1 and B2 are butted together in this way, the wiring storage space G of one desk B1 and the wiring storage space G of the other desk B2 are connected and integrated through the two outward openings E. This not only makes it possible to store many excess cords, but also makes it possible to comfortably store large outlet boxes and numerous connectors, etc. This eliminates or alleviates the inconvenience of having to expose and arrange various devices and cords outside the desk B.

[0047] Moreover, in this desk B or desk system A, the desk B is configured so that the tabletop 3 can be raised and lowered by extending and retracting the legs 11, 12, allowing for efficient work by appropriately changing the height position of the tabletop 3. In this case, in this embodiment, an outward opening E is provided in the housing 13 of the leg structure 1, which does not rise and fall, and a wiring storage space G is provided within each housing 13. Therefore, even if the height positions of the tabletops 3 of the left and right desks B are made different from each other, the positions of the openings E always match, allowing the two wiring storage spaces G to be constantly in communication with each other.

[0048] Furthermore, in this embodiment, since the wiring storage space G is provided in a position directly facing the existing floor surface J, it is easy to guide cords that extend from the floor surface J into the wiring storage space G. Furthermore, based on the configuration of this desk system A, if the wiring storage space G is provided in a position directly facing the existing floor surface J, it is possible to obtain an effect of increasing the degree of freedom in the installation position of the desk system A when guiding cords that extend from the floor surface J into the wiring storage space G. In other words, while it is often difficult to easily change the position at which cords extend from the floor surface J, if the opening width of the wiring storage space G that receives them is large, the cords can be easily introduced into the wiring storage space G without having to strictly manage the installation position of the desk system A. In this way, according to the present invention, since the locations at which signal transmission cords and power supply cords extend from the floor surface J can be shared, it is possible to obtain the effect of simplifying the wiring work and increasing the degree of freedom in the installation position of the desk system A.

[0049] Furthermore, in this embodiment, an interior lid 15 is also arranged on the inner surface of the wiring storage space G in an openable manner to open the wiring storage space G to the lower leg space formed below the top panel 3. This makes it easy to attach and detach the exterior lid 14, and simplifies the work of routing the wiring within the wiring storage space G and the work of attaching and detaching devices such as outlet boxes.

[0050] Furthermore, the above-mentioned desk B is configured so that each of the left and right ends of the tabletop 3 is supported by multiple legs, specifically, two legs 11 and 12 on each side, so stability can be ensured even if a large load acts on the tabletop 3 or the tabletop support frame 2, and particularly in the case of a lift-up type, it is possible to prevent large loads from being placed on the operation of each leg 11 and 12.

[0051] Furthermore, the desk B described above has a wiring storage space G formed between the front and rear legs 11, 12, so that a large wiring storage space G can be formed by effectively utilizing dead space.

[0052] It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0053] In the above embodiment, a desk system has been described in which two desks are butted together, but it goes without saying that three or more desks may be arranged in a row.

[0054] Furthermore, desks are not necessarily limited to those having a wiring storage space formed within the leg structure; for example, if the top is supported by left and right sleeves, various modifications are possible, such as forming a wiring storage space within the sleeves and making the outer wall surfaces of the sleeves correspond to the side end surfaces of the desk body.

[0055] Furthermore, the desk is not limited to a desk with a liftable top, but may have a fixed top. However, if a desk with a liftable top has a space for storing cables and an outward opening in the non-liftable part, it is possible to independently adjust the height of the top of the desk that is adjacent to it.

[0056] The cable insertion spaces do not necessarily have to be located directly above the existing floor, but this configuration allows the pair of adjacent cable storage spaces to be connected together even on the existing floor. This makes it particularly easy to route cords extending from the floor to either of the cable storage spaces, and allows the relative positions of the cords extending from the floor and the desk to be freely selected within the width of the pair of cable storage spaces. This configuration also makes it easy to fine-tune the position of the desk after installation.

[0057] Furthermore, the shape of the outward opening that opens the wiring storage space outward, and the shape and structure of the exterior lid that is attached to this opening are not limited to those shown in the illustrated embodiment, and various modifications are possible. For example, since the exterior lid is often removed when desks are butted together, the outer surface of the exterior lid and the side end surface of the desk body do not need to be flush with each other, and any shape may be used as long as it does not deviate from the spirit of the present invention.

[0058] In the illustrated embodiment, the exterior cover is screwed to the desk body from the wire insertion space side, but this mounting structure is not limited to this. For example, the exterior cover may be detachable from the outside. However, the screw-fastening structure of the illustrated embodiment not only simplifies the configuration but also makes it possible to effectively utilize the nuts t that remain after removing the exterior cover 14. For example, the bracket u attached to the left desk B1 of the desk system A shown in FIG. 1 is used to attach a partition panel (not shown) to the side of the desk body, and is attached to the desk body C using the nuts u. Incidentally, the bracket v in FIG. 2 is used to attach a partition panel (not shown) to the back side of the desk body C.

[0059] Of course, the cords and devices stored in the wiring storage space are not limited to those described above.

[0060] In addition, various modifications are possible within the scope of the present invention. [Explanation of symbols]
