Description

  The present invention relates to furniture with a top plate that can perform a suitable wiring operation.

  2. Description of the Related Art Conventionally, a structure in which furniture with a top plate such as one large table is configured by adding a plurality of furniture with a top plate is known. In such a thing, a frame is formed as a basic frame for supporting the top plate in one piece of furniture with a top plate, and a plurality of furniture with a top plate are connected by connecting adjacent frames to make a large table Is used (see, for example, Patent Document 1). However, in the furniture with a top plate having such a configuration, since the frame structure is used to increase the strength, there are problems that the number of parts is large, the manufacturing cost and the transportation cost are increased, and the assembly process is complicated. . In addition, if an opening is formed in the side frame constituting the frame body, horizontal wiring between adjacent furniture with a top plate is possible, but the opening is concealed in a curtain plate attached to the frame frame, so that maintenance is performed. There is also the problem that is troublesome.

A table-type free address desk is being considered as a solution to such a problem. In such a desk, a side end support that supports the side end of the top plate, an intermediate support that supports the center of the top plate, and a plurality of horizontal rails spanned between these supports. A support structure for the top plate is configured (see Non-Patent Document 1, for example). The desk having such a configuration is configured such that adjacent desks can be added to each other by connecting the adjacent horizontal rails in the longitudinal direction via the intermediate support.

  However, with such a configuration, it is necessary to make the crosspieces relatively thick in order to increase the rigidity of the support structure, and it is also necessary to particularly strengthen the connection between the crosspieces and both supports. There is. For this reason, wiring between adjacent desks must be performed while avoiding the intermediate support, and wiring work and maintenance are extremely complicated. That is, since the intermediate support has a structure giving priority to the connection strength, it can be said that the function for wiring is impaired.

  In view of the above-described problems, the present invention is intended to provide a furniture with a top board that includes intermediate legs that can easily route a wiring cord between spaced wiring ducts.

That is, the furniture with a top plate of the present invention comprises a top plate, a support structure that supports the top plate, and a wiring duct that can store a wiring cord in a space below the top plate, The support structure is disposed between a plurality of end legs that support the side end portions of the top plate, an intermediate leg that is disposed inside the end legs, and an end leg that is adjacent to the top plate in the depth direction. A side frame that supports the top plate, an arm that is supported by the upper end portion of the intermediate leg and supports the top plate, and a horizontal frame that connects the side frame and the arm, and is located at a position sandwiching the intermediate leg. It is premised that a plurality of wiring ducts are arranged and openings are formed in the intermediate leg so as to communicate with the wiring space formed in the wiring ducts arranged on both sides thereof.

  In the furniture with a top plate having such a structure, the connecting structure of the side frame, the arm, and the horizontal frame realizes high rigidity of the support structure, and the wiring duct sandwiches the intermediate leg through the opening formed in the intermediate leg. Since the wiring cord can be easily passed between them, it is necessary to route the wiring cord around the intermediate leg as in the conventional case, so that the trouble can be solved and the work and maintenance of the horizontal wiring can be performed easily. It becomes like this.

  Furthermore, in order to simplify the wiring work, the bottom plate portion of the wiring duct constituting the bottom portion of the wiring space and the opening lower edge portion of the opening portion formed in the intermediate leg are set at substantially the same height position. It is desirable.

  Further, in order to easily form an opening in the intermediate leg, the intermediate leg is provided with a pair of leg struts that are spaced apart by a predetermined distance, and a connecting member that connects the leg struts. What is necessary is just to let the site | part enclosed by the inner end of an adjacent leg support | pillar, and the upper end of a connection member be the said opening part.

The furniture with a top plate according to the present invention is opened up and down to the connecting member, to the side end side of the top plate , in order to suitably guide the wiring raised from the floor to the wiring duct through the opening of the intermediate leg. An extending recess is formed, and this recess serves as a wiring guide path communicating from the lower end of the intermediate leg to the opening .

  In order to conceal the wiring cord in the wiring guide path, a cover body that closes the wiring guide path so as to be opened and closed may be provided on the intermediate leg.

  In order to achieve the stability of the furniture with the top plate and the optimal use condition of the wiring duct, the intermediate leg is placed in the center of the top plate in the depth direction, and the wiring duct is placed on both sides of the intermediate leg. It is preferable to arrange along the direction.

  In particular, when the top plate has use ends at both ends in the depth direction, in order to make it possible for the workers at both use ends to use the wiring duct equally, in the width direction of the center portion in the depth direction of the top plate. It is desirable to form a gap extending along the gap and communicate this gap with at least the opening of the intermediate leg. As a configuration that can easily realize such an aspect, the top plate includes a pair of top plate elements adjacent to each other in the depth direction, and the use end of these top plate elements is used as the use end of the top plate. And what formed the clearance gap between the counter-use ends of a top plate element is mentioned.

  In addition, in order to minimize the obstacle to the leg of the worker sitting on the use end side due to the presence of the intermediate leg, the intermediate leg is arranged in the center in the depth direction of the top board, and the use side of the top board is used. The front end face of the intermediate leg that faces the inside should be set to the inner side of both use ends of the top board.

  According to the present invention, even if a plurality of wiring ducts are arranged so as to sandwich the intermediate leg, the wiring cord can be routed between the wiring ducts through the opening formed in the intermediate leg, so that the detour wiring work and the narrow Since it is not necessary to route the wiring cord to the space, it is possible to realize a very simple wiring operation, in particular, simple horizontal wiring to the wiring duct passing through the intermediate leg and extending to both sides thereof. Furthermore, it is possible to achieve high rigidity of the support structure by adopting a connection structure using the side frame, the arm, and the horizontal frame.

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

  The furniture with a top plate shown in FIGS. 1 and 2 is a large table T used in a so-called free address type office where the seat is not limited. The table T is mainly composed of a top plate 1, a support structure 2 that supports the top plate 1, and a wiring duct 3 that is disposed in a space below the top plate 1.

  In this embodiment, the top plate 1 is composed of a plurality of top plate elements 11. Specifically, four top plate elements 11 having a rectangular shape in plan view are used, and two of the top plate elements 11 and 11 are arranged as a set so that their counter-use ends 11b face each other. By arranging the sets of the top plate elements 11 and 11 with their inner ends 11c adjacent to each other, the counter-use ends of the top plate elements 11 are gathered at the center in the depth direction of the entire top plate 1, and the depth direction The use end 11a of each top plate element 11 is positioned at both ends. Note that a gap 1s of a predetermined distance is formed between the counter-use ends 11b, 11b of the top plate elements 11, 11 that are paired in the front-rear direction. The gap 1s communicates with the wiring space 3s of the wiring duct 3.

  The support structure 2 includes a total of four end legs 21 arranged in the vicinity of the outer end 11d on the use end 11a side of each top plate element 11 and end legs that make a pair in the depth direction of the top plate 1. 21, 21 side frames 22, 22 connecting each other, one intermediate leg 23 arranged on the inner end 11 c side on the counter-use end 11 b side of each top plate element 11, and each intermediate leg 23 supported by each intermediate leg 23. A total of eight arms that connect the pair of front and rear arms 24, 24 supporting the inner end 11 c side of the top plate element 11 and the side frames 22, 22 and the arms 24, 24 along the width direction of the top plate 1. A horizontal frame (four first horizontal frames 25, 25, 25, 25 and second horizontal frames 26, 26, 26, 26) is mainly configured. Here, the first horizontal frames 25, 25, 25, 25 support the counter-use end 11b side of each top plate element 11, and the second horizontal frames 26, 26, 26, 26 are each top plate. The center of the element 11 in the depth direction is supported. The left and right side frames 22 and 22 are attached with side curtain plates 27 and 27 that block the space below the top plate 1 from the side line of sight.

  Here, the structure of the intermediate leg 23 and its peripheral part will be described in detail. First, as shown in FIGS. 3, 4, and 5, the intermediate leg 23 is mainly composed of a pair of leg columns 231 and 231 that are spaced apart from each other by a predetermined distance in the depth direction of the top plate 1. Each leg column 231 is a member that has a channel shape that opens on opposite sides and stands on the floor. In the present embodiment, each leg support 231 is formed by bending a metal plate or extruding a metal material, and a pair of left and right side walls 231b and 231b that are continuous with both end portions of the front wall 231a. A pair of left and right rear walls 231c and 231c continuous with the side walls 231b and 231b are integrally provided, and the inner ends of the rear walls 231c and 231c are separated from each other. In addition, in the upper end part of each leg column 231, the rear end part of the side walls 231b and 231b corresponding to the counter-use end 11b of the top plate element 11 is partly cut out in a rectangular shape, and the rear wall 231c 231c is not provided. Such leg struts 231 and 231 are coupled by a pair of left and right connecting members 232 at a portion where the rear walls 231c and 231c are provided. Each connecting member 232 includes outer walls 232a and 232a that contact the inner surfaces of the side walls 231b and 231b of the leg columns 231, 231; opposing walls 232b and 232b that contact the inner surfaces of the rear walls 231c and 231c; and the opposing walls 232b and 232b. The inner wall 232c that connects the two and contacts the tip of the rear walls 231c and 231c is formed by bending a single metal plate. The side walls 231b and 231b and the outer walls 232a and 232a, the rear walls 231c and 231c, and the opposing walls 232b and 232b are fixed by welding or the like, thereby connecting the leg columns 231 and 231 with the connecting members 232 and 232. . Thus, in the present embodiment, a rectangular space as viewed from the side, surrounded by the upper end of the connecting member 232 and the inner ends of the opposing leg columns 231, 231, is formed in the left-right direction, that is, in the width direction of the top plate 1. The opening 23s is opened.

  Further, in this intermediate leg 23, a recess 23u that extends in a channel shape vertically and opens outwardly and communicates with the opening 23s by the opposing walls 232b, 232b and the inner wall 232c of the connecting member 232 on the left and right sides. , 23u are formed, in this embodiment, these recesses 23u, 23u are used as wiring guide paths 23r, 23r for guiding a wiring cord (not shown) that is raised or pulled down from the floor. Channel-shaped cover bodies 233 and 233 having a U-shape in plan view are detachably fitted in these recesses 23u and 23u so that the wiring cords in the wiring guide paths 23r and 23r can be concealed.

Further, in order to conceal the internal structure of the intermediate leg 23 in the opening 23s, a closing member 234 is attached to the leg posts 231 and 231. The closing member 234 has a planar letter-shaped shape placed on the rear walls 231c of the leg columns 231, 231 and the opposing wall 231b facing the opening 23s so as to avoid the wiring guide paths 23r, 23r described above. The horizontal wall 234a, the vertical walls 234b and 234b rising from both front and rear ends of the horizontal wall 234a so as to close the opening 3a from the inner side, and the leg struts 231 corresponding to the left and right ends of each vertical wall 234b continuously. Contact walls 234c and 234c fixed to the inner surfaces of the opposing walls 232b and 232b by welding or the like. The upper end portion of each leg column 231 is also closed by a plate-like member (not shown). In addition, since the above-mentioned leg support | pillar 23 is sufficiently thinner than the depth dimension of the top plate 1, the front wall of each leg support | pillar 231 used as the front-end surface in the intermediate leg 231 whole facing the use end 11a of the top plate 1, 11a. The front end surface 231a ₁ of 231a is arranged inside the use ends 11a and 11a of the top plate 1.

  With respect to such an intermediate leg 23, the pair of front and rear arms 24, 24 are in the form of a flat square pipe, and the counter-use ends are placed on the corresponding leg posts 231, 231 respectively. They are connected to each other by a flat rectangular pipe-shaped connecting rod 241 inserted therein. Further, the connecting rod 241 is fixed to the intermediate leg 23 using bolts 235a via a total of four L-shaped fittings 235 attached to the inner surface of the opposing wall 232b of each leg column 231 by welding or the like. ing. Further, a lid 242 is attached to the connecting rod 241 from above so as to prevent the connecting rod 241 and the inside of the arms 24, 24 from being seen from the gap 1s between the top and bottom plate elements 11, 11. . The lid 242 includes a horizontal wall 242a that is placed at the center in the depth direction of the connecting rod 241 and a standing piece 242b that stands up from both front and rear ends of the horizontal piece 242a and closes the inner ends of the arms 24 and 24, 242b and hanging pieces 242c and 242c that hang down from the left and right ends of the horizontal piece 242a and hide the side surface of the connecting rod 241 exposed from the arms 24 and 24. The horizontal piece 242a is connected to the connecting rod 241. On the other hand, it is fixed using a bolt 242d. Note that a through hole 242s (not shown for the through hole of the connecting rod 241) is formed in the horizontal piece 242a of the connecting rod 241 and the lid body 242, and the opening of the intermediate leg 23 is opened through the through hole 242s. The part 23s and the gap 1s between the top plate elements 11 and 11 are communicated with each other.

  As described above, in the support structure 2 in the present embodiment, the arm 24 and the side frame 22 are connected by the four first horizontal frames 25 and the second horizontal frames 26. The second horizontal frame 26 is connected to the arm 24 and the side frame 22 at each side end portion using a structure using bolts and nuts as described later in an oblique direction. Here, this connection structure will be described by taking as an example a connection portion between the first horizontal frame 25 and the arm 24 as shown in FIGS. 4, 6, and 7. First, connecting bodies 28, 28 protruding to both sides of the arm 24 are attached to the arm 24, and the first horizontal frames 25, 25 are attached to the arm 24 via these connecting bodies 28, 28. Specifically, each connecting body 28 is in the form of a metal block integrally formed by, for example, aluminum die casting or the like, and has a pair of bolt insertion holes 28a, 28a communicating with both sides. Formed. A bolt head accommodation hole 28b is formed at the outer end of one bolt insertion hole 28a, and a nut accommodation hole 28c is formed at the outer end of the other bolt insertion hole 28a. In the state where the same coupling bodies 28, 28 are arranged on the left and right of the arm 24 at the same direction, the shaft portion of the bolt 28d inserted into the bolt insertion hole 28a from the bolt head accommodation hole 28b side in one coupling body 28 is provided. The arm 24 is inserted into the bolt insertion hole 28a in the other connecting body 28 across the arm 24, and fastened to the nut 28e waiting in the nut accommodation hole 28c connected to the bolt insertion hole 28a, thereby a pair of connections to the arm 24. The bodies 28 and 28 are fixed. The positioning of the coupling body 28 with respect to the arm 24 is performed by uneven engagement between a projection 28f projecting on the inner end surface of the coupling body 28 toward the arm 24 and a projection housing hole 24a formed in the arm 24 correspondingly. Done. Further, a vertical hole 28g capable of accommodating a nut holding member 281 provided with a nut 281b for fixing the first horizontal frame 25 is formed in the central portion in the width direction of the coupling body 28. The vertical hole 28g The nut holding member 281 is inserted and held from below. The nut holding member 281 is a member made of, for example, a synthetic resin, which is formed by fixing the nut 281b in a posture inclined obliquely upward and outward, and an elastically deformable claw portion 281a formed on the upper end portion is provided in the vertical hole 28g. It is made to attach to the connection body 28 by engaging with the step part 28ga. Further, the connecting body 28 is formed with a window portion 28h for allowing the nut 281b to be exposed obliquely upward and outward.

  On the other hand, a fixing pin 251 for attaching to the coupling body 28 is attached to the inner end portion of each first horizontal frame 25 in the depth direction using a fixing tool such as a C ring 252. The fixing pin 251 is formed with a bolt insertion hole 251a that opens obliquely so as to be linearly aligned with the screw hole of the nut 281a of the nut holding member 281 attached to the coupling body 28. The bolt insertion hole 251a has a bolt insertion hole 251a. The shaft portion of the bolt 253 inserted obliquely from above is fastened to the nut 281a through the window portion 28h. An opening window 25 a is formed at the inner end of the upper surface of the first horizontal frame 25 in order to insert and remove the bolt 253 into the first horizontal frame 25. Moreover, since the lower end part in the inner side edge part of the 1st horizontal frame 25 is cut off diagonally, the operation | work which attaches so that the 1st horizontal frame 25 may cover the outer side edge part of the coupling body 28 from upper direction can be performed smoothly. I can do it.

  That is, as described above, the nuts 281a and the bolts 253 fixed to the connecting body 28 are obliquely tightened to fix each first horizontal frame 25 to the arm 24, whereby a high mounting strength can be obtained. The horizontal frame 25 is designed to eliminate vertical displacement and bending. Furthermore, since sufficient attachment strength can be obtained even when the height dimension of the first horizontal frame 25 is relatively small, a sufficient space for providing the wiring duct 3 described later can be secured. As described above, such a connection structure is common to the arm 24 and the side frame 22, the first horizontal frame 25, and the second horizontal frame 26. The thinning of the side frame 22, the first horizontal frame 25, and the second horizontal frame 26 is realized. It should be noted that the connecting body 28 and bolts or the like are appropriately attached to the side frame 22.

  As shown in FIGS. 1, 2, 3 and 4, the wiring duct 3 is formed at the center of the top plate 1 in the depth direction, that is, at the counter-use ends 11b and 11b of the top plate elements 11 and 11 that make a pair in the front and rear. The duct body 31 is disposed below and includes a duct body 31 having a wiring space 3s and a door portion 34 that opens and closes the use end 11a side of the top plate element 11 of the wiring space 3s. In particular, in the present embodiment, the top plate elements 11 and 11 paired in the depth direction are provided with one wiring duct 3, and the top plate 1 has a use end 11a at both ends in the depth direction. Therefore, the duct main body 31 is provided in a pair on the left and right, and two door portions 34 and 34 are provided on each duct main body 31.

  More specifically, each duct body 31 further includes a wiring tray 32 for receiving a wiring cord below the first horizontal frames 25, 25, and left and right ends of the wiring tray 32. It comprises a pair of left and right supports 33 supported between the horizontal frames 25 and 25. Each wiring tray 32 has a bottom plate portion 321 that is shorter than the width dimension of the top plate element 11, and upright plate portions 322 and 322 that stand at both front and rear ends of the bottom plate portion 321. In the present embodiment, the bottom plate 321 and the upright plate portions 322 and 322 are formed by bending a single metal plate. On the other hand, each support body 33 has an E-shape in side view and stands on the outer side of both end portions of the wiring tray 32 and a pair of front and rear first continuous with the upper end portion of the main body plate portion 331. A pair of mounting plate portions 332 and 332 extending along the opposing surfaces of the horizontal frames 25 and 25, and a pair of support plate portions 333 receiving the bottom plate portion 321 of the wiring tray 32 from below from the lower end portion of the main body plate portion 331. 333. In the present embodiment, each support 33 is formed by bending a single metal plate. Then, the mounting plate portions 332 and 332 are positioned between the first horizontal frames 25 and 25 and fixed to their opposing surfaces using screws, while the wiring tray 32 is placed on the support plate portions 333 and 333. It is fixed using screws. The bottom plate portion 321 of the wiring tray 32 is provided at substantially the same height as the opening lower edge 23sa of the opening 23s of the intermediate leg 23. By doing so, the opening 23s, the wiring spaces 3s and 3s on both sides thereof, the wiring guide paths 23r and 23r, and the gap 1s are all in communication, and the wiring cord can be freely passed through these parts. I can do it.

  The door 34 includes a door main body 341 made of a single metal plate, and a support shaft 342 for attaching the door main body 341 to the duct main body 31. First, the door main body 341 is made of, for example, punching metal having a large number of holes, and a support shaft 342 is attached to the upper end 341a. The end portions of the support shafts 342 protrude from the side end portions of the main body portion 341. Further, a handle portion 343 is attached to the outer surface side of the door portion main body 341 so that the opening and closing operation of the door portion 34 can be suitably performed. In the present embodiment, the handle portion 343 is attached to the lower half portion of the central portion in the width direction of each door portion main body 341. In order to support the door 34 with the duct main body 31, a bearing member 344 is attached to each mounting plate 322 of the duct main body 31. The bearing member 344 has a holding claw part 344a for detachably attaching the support shaft 342 by elastic deformation and holding it rotatably, and an attachment part 344b for attaching to the attachment plate part 322. The part 344b is attached to each mounting plate part 332. With the attachment portion 344b fixed to the attachment plate portion 322 by elastic deformation, the support claw portion 344a supports the support shaft 342 so that each door portion 34 can rotate relative to the duct body 31 at the upper end portion 341a. The lower end portion of the door portion 34 becomes an open end portion 341b that is not supported anywhere. Therefore, as shown in FIG. 4, each door portion 34 is pivoted to the front side around the support shaft 342 if the handle portion 343 is gripped and pulled up to the use end 11 a side of the top plate element 11, or On the contrary, if the door main body 341 is pushed into the wiring space 3s, the door body 341 rotates and tilts around the support shaft 342, so that the wiring code (not shown) can be taken in and out of the wiring space 3s by any of these operations. Or maintenance can be performed. Further, a curtain plate 35 is provided at the center of the duct body 31 in the depth direction in order to block the line of sight from the one use end 11a side to the other use end 11a side of the table T. Specifically, the same member as the door 34 described above is used for the curtain plate 35. That is, the curtain plate 35 includes a curtain plate main body 351 having the same configuration as the door main body 341 and a support shaft 352 having the same configuration as the support shaft 342. On the other hand, bearing members 344 are attached to both end portions of the raised portion 321a of the wiring tray 32 from below, and the curtain plate 35 is attached to the duct body 31 by holding the support shaft 352 on the bearing member 344. .

  According to the table T according to the present embodiment having the above-described configuration, a pair of wirings provided on the intermediate leg 23 supporting the central portion of the top plate 1 and provided with openings 23s on both sides of the intermediate leg 23. Since the wiring spaces 3 s and 3 s of the ducts 3 and 3 are communicated with each other through the opening 23 s, the wiring cord can be easily passed between the wiring ducts 3 and 3. The necessary wiring work can be eliminated. In addition, a very inconvenient wiring operation in which a narrow space is formed between the leg structure 2 and the top plate 1 and a wiring cord is passed through the space can be eliminated. In particular, since the opening lower edge 23sa of the opening 23s of the intermediate leg 23 is set at a height position substantially equal to the bottom plate 321 of the wiring duct 3, the wiring cord extending between the wiring ducts 3 and 3 is substantially horizontal. Since it can be arranged straight, a large number of wiring cords can be stored in the wiring duct 3 and the wiring work can be performed more easily.

  In particular, in the present embodiment, the pair of leg columns 231 and 231 arranged in the depth direction of the top plate 1 are arranged apart from each other and coupled by the coupling member 232, thereby connecting the inner ends of the leg columns 231 and 231 and the coupling member 232. Since the portion surrounded by the upper end of the opening is the opening 23s, the opening 23s can be easily formed. The connecting member 232 has recesses 23r and 23r formed by the opposing walls 232b and 232b and the inner wall 232c, and wiring guide paths 23s and 23s for guiding the wiring up and down using the recesses 23r and 23r. Since the wiring guide paths 23s and 23s communicate with the opening 23s, wiring work for power supply and the like can be easily performed. Further, the wiring guide paths 23s and 23s are covered with a cover. Since the bodies 233 and 233 are attached, the wiring cords inside the wiring guide paths 23s and 23s can be hidden.

Further, since the intermediate leg 23 and the wiring ducts 3 and 3 are arranged in the center of the top plate 1 in the depth direction, the intermediate leg 23 and the wiring duct are provided to a worker sitting on the use end 11a side of the top plate 1. 3 and 3 are not obstructed, and a gap 1s is formed between the counter-use ends 11b and 11b of the top plate elements 11 and 11 arranged in the depth direction. The wiring cord can be easily passed between 3s and the opening 23s. Further, since the depth dimension of the intermediate leg 23 is sufficiently smaller than the depth dimension of the top plate 1, the front end surfaces 231 a ₁ and 231 a _{1 of the} intermediate leg 23 are positioned inward of the use ends 11 a and 11 a of the top plate 1. This also eliminates obstacles to the workers' legs.

  The present invention is not limited to the embodiment described above. For example, a plurality of intermediate legs may be provided, and each intermediate leg or any of the intermediate legs may be provided with an opening through which the wiring cord straddling the wiring ducts can pass. When arranged along, intermediate legs having openings may be arranged between the wiring ducts. Further, a cover may be attached to the gap between the top plate elements, and the cover may be removed only when wiring work is performed. In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
