Description

  The present invention relates to a wiring cover device and a table system that can improve the usability of a wiring cover and can effectively respond to the diversification of layouts that have been recently required.

  Conventionally, many desk top plates with wiring holes are available on the market. Among these things, what has a mode which opens a wiring hole with a plurality of forms, for example, what is shown in patent documents 1 is mentioned.

  This is a wiring hole cover device comprising a wiring protection frame fitted to an opening of a top plate or the like and a wiring hole cover fitted to the wiring protection frame so as to cover the wiring protection frame. Consists of a pair of divided pieces, and these divided pieces extend from the back surface of one divided piece toward the other divided piece and have a pivot having a pivot point that pivotally supports the other divided piece at the tip. The supporting means is pivotally supported between a position where these divided pieces are arranged horizontally and a position which is substantially perpendicular to each other.

  Specifically, when both divided pieces are substantially perpendicular, the original upper surface of one of the divided pieces placed in the vertical state is positioned on a vertical surface that is substantially the same as the inner end surface of the other divided piece in the horizontal state. Is configured to do. In addition, a receiving hook for contacting the wiring hole cover is provided on the inner walls facing each other of the wiring protection frame, and a passing portion for allowing one divided piece pivoted in a vertical state to pass through the central portion of the receiving hook.

  However, in such a structure, the bottom of each divided piece is supported by a receiving rod at the mounting position and cannot be rotated downward. To drop the divided piece, the wiring hole cover is once removed and bent into a vertical state. After that, it must be reattached to the wiring hole. For this reason, workability is poor. In particular, even if an article such as an outlet is arranged directly under the wiring cover, it is easy to interfere with the divided piece and keep it waiting, and it is also difficult to provide a relatively shallow wiring receiver under the wiring hole. Furthermore, it is troublesome because the wiring hole cover must be removed again when closing the wiring hole. Furthermore, it is desirable for both sides to easily access the wiring holes when sitting face-to-face, but this is also inconvenient.

  It is an object of the present invention to provide a wiring cover device and a table system that can improve the usability of such a wiring cover and can effectively respond to the diversification of layouts that have recently been required.

  In order to achieve this object, the present invention takes the following measures.

That is, the wiring cover device of the present invention is configured so that the wiring cover can be detachably attached to the wiring opening of the top plate, and the wiring cover includes a first lid supported by the wiring opening and the first cover. The first lid is rotatably supported by one lid, and the first lid has an edge perpendicular to these edges in the vicinity of the edge on the one end side and the edge on the other end side, respectively. It is also arranged in the wiring opening through the bearing part made of a combined structure, and also stands in the direction of standing up on one end side depending on whether the bearing of the bearing part near the edge on one end side or the other end side is disengaged from the bearing It has a double-open structure that can be rotated in the direction of standing on the other end side, and is detachable with respect to the wiring opening by engaging or disengaging the bearings with the shafts of all the bearings. Furthermore, the second lid is the first lid. Of are those that are provided at positions to open and close the notch provided on at least one of one side or the other end, a first lid of the pair is common in the state aligned in the short-sized direction of the first cover It is attached to the position which closes a wiring opening.

  If comprised in this way, since the 1st lid can be rotated in either direction with the second lid attached, it is not necessary to remove the entire wiring cover from the wiring opening one by one, Workability is improved, and this operation does not hinder placing an article such as an outlet directly below or providing a relatively shallow wiring receptacle. Furthermore, the wiring opening can be easily opened on either side when seated facing each other. Then, after the wiring process, only the second lid can be opened and kept in a line-connected state, so that the appearance can be easily adjusted after the wiring process. In this way, it is possible to provide a wiring cover device that can easily cope with diversification of layouts.

  In order to facilitate the wiring processing work and cope with the diversification of the layout, the wiring cover is made detachable from the wiring opening by engaging or disengaging the bearings with the shafts of all the bearings. It is desirable that

  In particular, it is preferable that the bearing portion can be mounted even if the wiring cover is turned 180 ° in plan view.

The present invention, the second cover is characterized in that provided in pairs in a position to open and close the opening provided in both of the one end side and the other side of the first lid.

In order to make it possible to form a new wiring hole in accordance with the arrangement, thereby increasing the variety of layouts, the present invention is provided with a second lid at a position for opening and closing the notch of the first lid. When the first lid is attached to a position where the common wiring opening is closed, the second lid attached to the first lid is adjacent to the first lid, and the second lid attached to each first lid is opened, thereby opening the second lid. characterized in that each opening the lid had been closed is so as to form a continuous opening.

  Using the wiring cover device as described above, when configuring the table system so as to close the wiring openings provided in the small table and the standard table on the top plate surface equal to a multiple of the top plate surface of the small table, In order to keep the wiring processing function constant and improve usability regardless of the layout, set the standard table wiring opening to a multiple of the small table wiring opening and close the small table wiring opening. It is desirable to collect a plurality of wiring covers to be closed so that the wiring openings of the standard table can be closed.

  In order to develop various variations using both the standard table and the small table, the small table has a notch-shaped wiring opening at the position where it opens to the edge side, and a wiring cover is attached to this wiring opening. In addition, a closed wiring opening corresponding to the wiring opening of the standard table is formed by abutting the edges of the small table, and a large table equivalent to mounting a plurality of wiring covers on the wiring opening of the standard table is configured. It is desirable to be able to do so.

  In order to cope with diversification of layouts with a simple configuration, the top of the standard table is a square, and the top of the small table is a rectangular shape corresponding to the top of the standard table. It is suitable.

  Since the present invention has the configuration described above, the first lid supported by the wiring opening and the second lid rotatably supported by the first lid are preferably used in combination. It is possible to provide a wiring cover device and a table system that can improve the usability of the cover and can effectively respond to the diversification of layouts that have been recently required.

  As described above, the table A according to the present embodiment is such that the main wiring receiver 6 is attached to the lower surface of the central portion of the top plate 3, and the extension wiring receiver 7 can be attached to the main wiring receiver 6. However, as shown in FIG. 14, the table A of this embodiment has a use area 3α (which is applied to a standard occupant's lower limb space between each top plate edge 3x under the top plate and a predetermined position in the inner depth. (A)), and a use area 3β (FIG. (B)) applied to a storage space of a storage member such as a wagon is set, and the plurality of use areas 3α and 3β are not overlapped in plan view ( The plan view dimensions of the extension wiring receiver 7 are set so as to fit in the (enclosed position), and the extension wiring receiver 7 is attached to the position in a state of hanging from the main wiring receiver 6 as shown in FIG. I have to. The main wiring receiver 6 is attached to the lower surface of the top plate and is flat, but the main wiring receiver 6 is also provided at a position that does not overlap with these use regions 3α and 3β in a plan view (enclosed position). It is.

  Furthermore, a wiring duct 8 shown in FIG. 13 can be connected to these wiring receivers 6 and 7 as required. The wiring duct 8 is a channel-like opening that is provided with upright pieces 82 and 82 on both sides of the bottom wall 81 and opens upward. The ends of the upright pieces 82 protrude in the longitudinal direction from the bottom wall 81 and the mounting pieces 83 are formed. Forming. Then, the mounting piece 63 is inserted into a position where it overlaps with the upright pieces 62 and 72 via the gaps 65 and 75 of the wiring receivers 6 and 7, and screw insertion holes 62a provided in the upright pieces 62 and 72 at that position. The main wiring receiver 6 and the wiring duct 8 or the extension wiring receiver 7 and the wiring duct 8 can be connected by using the screw insertion hole 8 a provided in the mounting piece 83. Of course, this table system also includes a main wiring receiver 6 and an auxiliary wiring receiver 7 in a mode in which a clearance similar to the clearance 65 is provided between the rising pieces 63 and 73 on the side of the rising pieces 62 and 72 ( It is also possible to connect the wiring duct 8 in a direction orthogonal to the illustrated example.

  Next, the function of connecting the standard tables of this embodiment configured as described above will be described.

  Since the standard table A is movable by the casters 21 as described above, and the structure is lightweight with a four-leg structure, it can be moved on the floor very easily. Then, the top plate edge portions 3x and 3x are abutted to each other, and the top plate edge portion between the main wiring receptacles 6 and 6 or between the extended wiring receptacles 7 and 7 at that position is shown in FIGS. 13 (a) and 13 (b). By connecting with the wiring duct 8 so as to pass between the pair of 3x legs 2 and 2, the positional relationship between the top plates 3 and 3 is connected via the wiring receiver 6 (7) as shown in FIG. Thus, it can be temporarily connected so as to be maintained by the wiring duct 8, and the continuous wiring function is ensured, and the top plate 3 can be used as the island-shaped arrangement table B in a state of being substantially flush. Further, as described above, the adjuster function is attached to the caster 21, and the adjuster is grounded by the lever operation and the table A is fixed. Therefore, combined with the connection structure by the wiring duct 8, the table B having the island type arrangement is provided. As a result, a state that can be used stably is obtained. This table system also has a function of connecting the top plates 3 and 3 with an auxiliary connector g1 as shown in FIG. 15 as necessary. In the illustrated example, a receiving member g2 made of resin or the like can be attached in the vicinity of the corner of each of the top plate edge portions 3x, and the top plate edge portion is connected between these receiving members g2 by an auxiliary connecting device g1 such as a resin fastener. The continuity between 3x and 3x can be easily secured. The support g2 can be attached using the leg base attaching part 3A and the frame attaching part 3C shown in FIG. Furthermore, since this standard table A is lightweight, the connection between the wiring receivers 6 and 6 (7, 7) is not simply connected by the wiring duct 8, and simple connection using only the auxiliary connector g1 and the receiver g2 may be performed. it can. 2 (b) and 2 (c) show a state in which two connections are made using such a connection structure, but it is possible to increase the number of connections to three or more by the same structure.

  On the other hand, when performing more accurate connection, when the top plate edge portions 3x and 3x are brought into contact with each other, the top plate edge portion 3x side which is a butt edge portion of each top plate 3 is supported in FIG. A pair of legs 2, 2 shown in FIG. 6 and a pair of leg bases 1, 1 and a bridge-type leg 2x between them are used as the base-type leg 2x shown in FIG. Then, as shown in FIG. 16, the large top plate 30 is configured by replacing the top plate 3 and 3 adjacent to each other in the direction crossing (orthogonal) with the top plate edge 3 x in parallel. The large top plate 30 can be supported by the leg 2x that has been performed and the leg 2x that has not been replaced. In this embodiment, the replaced leg 2x is displaced from the position at which the top plate edge 3x on the butting side is supported to the top plate center side (center side with respect to the depth direction and the connecting direction), that is, the wiring. As shown in FIG. 2 (c), the leg 2 is retracted to the inner back of the top plate edge 30x of the large top plate 3 along with the hole 31. As a result, the lower limb space is continuous along the connecting direction of the top board 3, and a so-called wagon-free state in which the wagon WG or the like can be stored at any position along the longitudinal direction is realized.

  In this case, the end surface 4a between the frame members 4 and 4 connected to the replaced leg base 1 is opened, and a gap is generated between the end surfaces 4a and 4a. I am doing so. As shown in FIG. 17, the connecting member 40 is a U-shaped member having standing pieces 40 a at both ends. For example, the connecting member 40 is made by plastic deformation of a metal plate or the like, and the standing pieces 40 a are attached to the end surfaces 4 a of the adjacent frames 4. By fastening the screws inserted into the upright pieces 40a to the screw holes 4b of the frame member 4, the frame members 4 and 4 can be pulled together and connected. The connecting member 40 is fixed to the lower surface of the top plate 3 using the leg base attaching portion 3A. In the present embodiment, as shown in FIG. 16, the frame member 2 from which the leg base 1 has been removed and the frame mounting surface 12a of the replaced leg base 1 are set parallel to each other, and the connecting member 140 is further interposed therebetween. It is also possible to connect with. Although the illustrated example shows three stations, the number of stations can be increased to two or four or more by a similar connection structure.

  Moreover, since the said leg base 1 has the orthogonal | vertical mount attachment surface 12a, as shown to Fig.18 (a), even if it arrange | positions between the top boards 3 in L shape, the base material of the adjacent top board 3 is provided. The mounting surfaces 12a face each other in parallel, and L-shaped connection can be realized by connecting the mounting surfaces 12a with the frame member 8. Furthermore, if this property is utilized, it can be easily developed into a T-shaped connection table as shown in FIG. 5B and a cross connection table as shown in FIG.

  In this case, if the main wiring receptacle 6 and the auxiliary wiring receptacle 7 having the gaps 65 and 75 shown in FIG. 13 are used, the wiring receptacles 6 and 6 (between 7 and 7) according to the layout. Can be connected vertically and horizontally by the wiring duct 8. Since the wiring duct 8 at that time is set in a positional relationship passing through the inside of the replaced legs 2x and 2x, interference is effectively avoided, and the wiring duct 8 is connected to the wiring receiver 6 shown in FIG. , 7 from the top plate edge 3x, 3x at the opposite position from the positional relationship to the inside of the use area 3α, 3α (between 3β, 3β) set in two places, the use area 3α It is possible to realize the function of connection and continuous wiring vertically and horizontally while effectively avoiding interference with 3β.

  Further, this desk system can be used together with a small table D shown in FIG. 19 having a size obtained by dividing the top plate of the standard table A by an integer. The small table D has a notch-like wiring opening 131 opened on the top plate edge 103 x side on the top plate 103, and the top table 3 of the standard table A shown in FIG. This corresponds to a shape divided into two by a line parallel to the top edge 3x. The wiring opening 131 is also provided with a shaft portion 131a similar to the shaft portion 31a shown in FIG. 1, so that one wiring cover 5b shown in FIGS. I have to. Accordingly, the wiring cover 5b can be used together, and if the small tables D and D are abutted so that the wiring openings 131 are adjacent to each other as shown in FIG. 19B, the standard table A shown in FIG. It is also possible to construct a standard table A ′ having the same top plate area. In this case, it is effective that the wiring receiver is equivalent to the wiring receivers 7 and 8 when the wiring receivers 7 and 8 of the standard table A are halved by matching. The connection between the legs also follows the connection between the top plates 3 and 3 by replacing the legs 2x in the standard table A and the connection between the wiring receivers 7 and 7 (between 8 and 8) by the wiring duct 8. It is effective to adopt a different structure. The same applies to the auxiliary connector g1 and the like.

  In this way, different large tables A ′ can be configured by connecting the small tables D in a continuous manner, and can be easily developed in a layout in which the small table D is added to a part of the standard table A. it can.

  The side panel SP shown in FIGS. 2A to 2C is an upright surface in which the optional member mounting surface 11d is provided on the optional member mounting surface 11d of the leg base 1, as shown in FIGS. When the outlet box SC is disposed below the top plate edge 3x as shown in FIG. 1, an appropriate bracket is attached in the same manner as described above. The attachment can be realized by attaching to the optional member attachment surface 11d. As described above, each leg base 1 is provided with a plurality (two) of optional member mounting surfaces 11d, and various optional members such as a curtain plate for closing the lower limb space by using this are provided. Can be attached.

  Further, the desktop panel DTP shown in FIG. 2B can be attached to the opening edge of the opening hole 31 of the top plate 3 using the clamp p2 shown in FIG. The clamp p2 is formed by engaging a U-shaped base portion p20 in the wiring hole 31 shown in FIG. 1 so as to sandwich the top plate 3 in the thickness direction, and rotating a shaft portion p21 screwed to the base portion p20. The top plate 3 can be attached between the lower end of the shaft portion p21 and the lower piece of the base portion 20, and a support rod is inserted into the hole p22 provided in the shaft center portion of the shaft portion p21. The desktop panel DTP is raised. The base p20 is raised through the slit 53 shown in FIG.

  The desk system of the present embodiment configured as described above realizes a degree of layout freedom that is not found in a conventional desk system.

  In other words, the conventional table system uses a table system in which furniture can be arranged in various places and used as free addresses, or a table for realizing an island type opposing arrangement structure by appropriately connecting desks for one person. Whether using a system or using a table system that supports legs with a position that does not interfere with the lower limb space of the large top plate, specializing the structure based on any concept and building the layout with this structure It was customary. However, the required layout varies depending on the attributes and number of organizations to be used, organizational changes, and the like, so it does not always fit the user's needs.

  Specifically, if the user's needs for free table layout are roughly divided into two, one is to improve team building, eliminate boundaries with other departments, and change daily usage ( There is a type that emphasizes qualitative effects such as being able to respond to desk work and meetings, and being vibrant and inspiring creativity, and the other is that it can improve space efficiency and increase the number of people and organizational changes. It can be considered that there is a type that emphasizes quantitative efficiency, such as shortening and increasing the frequency of communication.

  However, for example, the conventional free address desk has the advantages of the former, but internal communication is not good, it is uncomfortable because the individual seats are narrow, and there is a disadvantage that the number of seats is insufficient when the enrollment rate is high, The conventional island-type facing structure has the advantage of the latter, but the connection direction is limited to one direction. Therefore, there is a problem that it is difficult to see what kind of office layout is optimal for the future. Furthermore, the conventional large table structure can cope with the increase or decrease of the number of people in the department, but the arrangement direction is also limited, so it is not suitable for the project team etc. mentioned above, and the top board area can be expanded. There is a problem that meeting and meeting are not possible in the desk space.

  In this way, the conventional desk is not supposed to be connected, or the connecting direction is extremely limited, and the structure according to the functions such as free address type, island type, large table type in advance Since it was created with strong attributes, using it alone inevitably tends to be biased towards either the qualitative effect-oriented layout or the quantitative efficiency-oriented layout. It was a thing.

  On the other hand, in this embodiment, the standard table A is connected vertically and horizontally, the wiring duct D is used to temporarily connect the tables A and A, and if necessary, the position of the leg 2x is changed. A strong connection between the top plates 3 and 3 and a wagon-free operation are realized, and a small table D is appropriately laid out and used in combination with the standard table A.

  And, since the standard table A of four legs is a basic structural unit and a plurality of the standard tables A are arranged, the nearest four leg table can be separated and concentrated as necessary. A square (rectangular) standard table A corresponding to a personal work is used as a reference, and this is arranged in a matrix form. By connecting and expanding as needed vertically and horizontally as needed, islands can be placed in the necessary locations in either direction. It can be developed on a mold table B or a large table C, and vice versa. Therefore, when the office space is laid out, the ratio between the qualitative zone and the quantitative zone can be appropriately set and changed according to the organization, and a fluid layout can be realized.

  As described above, the wiring cover device according to the present embodiment is configured such that the wiring cover 5 b can be detachably attached to the wiring hole 31, and the wiring cover 5 b is supported by the wiring hole 31. 51 and a second lid 52 rotatably supported by the first lid 51. The first lid 51 is orthogonal to these edges in the vicinity of the edge on one end side and in the vicinity of the edge on the other end side. The edges are arranged at the opening edge of the wiring hole 31 via the bearing portion having the engagement structure of the shaft 31a and the bearing 51b, respectively, and the shaft 31a and the bearing 51b of the bearing portion close to either edge on one end side or the other end side. Depending on whether the engagement is disengaged, a double-open structure is provided that can rotate both in the direction of standing on one end side and in the direction of standing on the other end side. Further, the second lid 52 is one end of the first lid 51. Position to open and close the notch 51a provided on the side It is those that are provided.

  With such a configuration, the first lid 51 can be rotated and raised in any direction with the second lid 52 attached, so that it is necessary to remove the entire wiring cover 5b from the wiring hole 31 one by one. In addition, the workability is improved, and it is also avoided that this operation hinders the placement of an article such as the outlet C directly below or the provision of the relatively shallow main wiring receiver 6 as in the present embodiment. be able to. Further, when sitting face-to-face, the wiring hole 31 can be easily opened on either side. Then, after the wiring process, only the second lid 52 can be opened and kept in a line-connected state, so that the appearance can be easily adjusted after the wiring process. In this way, it is possible to provide a wiring cover device that can easily cope with diversification of layouts.

  In particular, the wiring cover 5b is detachable from the wiring hole 31 by engaging or disengaging the shafts 31a and bearings 51b of all the bearing portions. Since it can be opened, it becomes easy to cope with diversification of layout.

  And since the bearing part of this embodiment can be mounted even if the wiring cover 5b is rotated by 180 ° in plan view, an opening is provided only on one end side of the first lid 51, and the second position is at a position to open and close it. For example, when the cover 52 is provided, it is easy to replace the wiring cover 5b in an appropriate direction.

  In addition, the second lid 52 can be easily provided in pairs at positions where the openings provided on both the one end side and the other end side of the first lid 51 are opened and closed. A state in which the wiring cover can be used equally from the facing seating position can be realized, and it becomes easy to cope with diversification of the layout.

  In addition, a second lid 52 is provided at a position where the notch 51a of the first lid 51 is opened and closed, and when the pair of first lids 51, 51 are attached to a position where the common wiring hole 31 is closed, the second lid 52 is provided. By opening the second lids 52 and 52 attached to each other and opening the second lids 52 attached to the respective first lids 51, the respective openings in which the second lids 52 are closed form continuous openings. Since it did in this way, a new wiring hole can be formed in the center, the function of the wiring cover 5b can be raised without difficulty, and it becomes easy to cope with diversification of layout.

  And the table system of this embodiment uses the said wiring cover apparatus, The wiring holes 31 and 131 each provided in the small table D and the standard table A of the top-plate surface equivalent to the double of the top-plate surface of this small table D are provided. The table system is configured to be closed, the wiring hole 31 of the standard table A is set to a multiple of the wiring opening 131 of the small table D, and a plurality of wiring covers 5b for closing the wiring opening 131 of the small table D are assembled. Since the wiring hole 31 of the standard table A can be closed, the standard table A and the small table D share the wiring cover 5b, and the standard table A and the small table D are combined to provide various layouts. Even in this case, the wiring processing function can be kept constant, the usability can be improved, and the layout can be easily adapted to diversification.

  Furthermore, the small table D of the present embodiment has a notch-like wiring opening 131 at a position opened to the edge side, a wiring cover 5b is attached to the wiring opening 131, and the edges of the small table D are further connected to each other.
