Description

The present invention relates to a table system that can easily and appropriately change the layout from a single state to a continuous state and facilitates separation again.

  Conventionally, a large table is generally formed by connecting a plurality of tables. In such a case, as shown in Patent Document 1, a leg positioned at the connecting side end is used as a common intermediate leg, and a top plate is added while adding a beam thereto, or as shown in Patent Document 2. The top plates are connected to each other by a connecting tool so that the legs are not positioned in the middle so as to ensure the continuity of the lower limb space, or as disclosed in Patent Document 3, the wiring duct is mainly used around the wiring duct. The top plate is assembled.

  Thus, as seen in these conventional examples, individual tables that constitute a large table by being assembled usually have an adjuster attached to the lower end, giving priority to stable installation.

  However, due to the recent variety of layouts, there is a need for a table system that has a certain degree of stable installation and fluidity such as relocation, expansion, and separation by moving rather than long-term stable installation. It is a fact.

  In such a case, it is conceivable that the table can be moved by attaching a caster to the lower end of the leg. For this purpose, it is desirable that the table be configured as simple and lightweight as possible. Further, since it takes time and cost to connect the top plates and the tables with beams, connecting members, wiring ducts and the like as in the above patent document, it is desirable that the caster can be fixed at a predetermined destination. However, simply locking the wheels of the casters is likely to cause a side slip when the table is lightened, and problems such as a gap between adjacent top plates are expected to occur. Also, even if the casters can be prevented from skidding, if the weight of the entire table is reduced and the mounting strength of the legs to the top plate is reduced, the legs will wobble, resulting in a gap between adjacent top plates. Can be.

In view of such a point, the present invention has a simple structure, but can easily and appropriately add a single table, and is less likely to cause a gap between the top plates. The purpose is to provide a table system with new functions.

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

That is, the table system of the invention, linked to other tables forming the same shape, the temporary connection or in butted edges portions of the top plate of the edge portion and the other table top board by a simple connecting top plate A table system that can be used as a large table by ensuring continuity between edges of the table, the table being attached to the top plate and a corner of the top plate, and from the corner to the top plate A leg base extending toward the inside of the base, a rod-like leg attached to the leg base so as to extend downward, and a caster attached to the lower end of the leg. the lower end of the grounding member protruding grounding member downward contacts in terms to the floor, with the ground member by the reverse operation is configured to immersive, those Coupling between the tables, the legs positioned at the center of the coupling direction when the temporary connection or a simple connection can be saved in the inner back of the top plate, casters attached to the lower end of the leg located in the center of the coupling direction, the operation portion The grounding member protrudes downward by an operation applied to the floor, and the lower end of the grounding member is in contact with the floor on the surface.

The table system of the present invention configured as described above can freely move on the floor when the caster is grounded. When the operation unit is operated at a predetermined movement destination, the grounding member protrudes downward and contacts the caster. The movement function is regulated. In this case, since the function of the caster is regulated by grounding the grounding member instead of locking the caster itself, the grounding area can be increased and the caster can be stably installed. Therefore, it is possible to effectively prevent a gap from being generated between the top plates due to the displacement of the grounding position without connecting the tables with a connecting member or a wiring duct at the position where the tables are brought into contact with each other. Furthermore, if the operation unit is operated in the reverse direction, the table can be moved again by the casters. As described above, a single table can be immediately added and separated again, and the degree of freedom in layout can be dramatically increased.

  At that time, this caster stabilizes the grounding state by protruding the grounding member, so even if the shape and size of the grounding surface and the table are reduced in weight, effective static frictional force can be achieved through the material etc. Can be granted.

  In particular, since the leg base for attaching the legs to the top plate spreads toward the inside of the top plate, the attachment state of the leg base to the top plate is stabilized, and as a result, the attachment strength of the legs can be increased, By bringing the legs close to the corner of the top as much as possible, the grounding distance between the legs can be increased and the stability of the grounding state can be improved.

  When the caster is grounded at a position displaced horizontally from the center of the leg and can swing around the center of the leg, the caster is adjusted by the caster when switching from the grounded state by the caster to the grounded state by the grounding member. In order to effectively prevent the ground contact state from shifting, the center of the ground member should be grounded at a position substantially the same as the position where the wheel is grounded in a side view as viewed from a direction orthogonal to the traveling direction of the caster. It is preferable that it is comprised.

  Alternatively, when the caster is grounded at a position displaced horizontally from the center of the leg and can swing around the center of the leg, it is optimal for switching from the grounded state by the caster to the grounded state by the grounding member. In order to obtain a stable installation state, it is also preferable that the grounding member is configured so that the center is grounded almost directly below the leg.

  In order to appropriately incorporate and function the grounding member, it is desirable that the grounding member is provided so as to be able to project and retract between a pair of wheels, and the grounding width is set to be smaller than the diameter of the caster.

  As a preferred embodiment of the grounding member, a shape or material that increases the frictional resistance with the floor as compared with the case where the lower end is configured to come into contact with the floor or when the caster is grounded in a locked state is used. What is provided in the lower end is mentioned.

  In order to effectively prevent a problem such as a gap between the top plates when the grounding member is properly grounded, four legs are arranged at the four corners of the top plate via the leg bases. Are connected between the upper ends of two adjacent legs via a leg base at the required location, and further, between the upper ends of the two legs via a leg base. It is preferable that the gate-shaped legs configured by connecting are arranged in pairs at positions that support the opposite edge portions of the top plate, and these legs are further connected by a frame. It is.

Since the present invention has the configuration described above, it is possible to easily and appropriately add a single table even if the configuration is simple, and the gap between the top plates can be eliminated without connecting the tables with a special connecting member. It is possible to provide a table system that can be easily separated from each other and can be easily separated from each other. Therefore, it is possible to provide stable installation and fluidity such as rearrangement, addition, and separation by movement. It can be suitably used for the construction of an office having both of the above.

  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 am doing so. 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 caster 21 has a lock function, and since the grounding member 20 is grounded and the table A is fixed by the lever operation, the island-type arrangement is combined with the connection structure by the wiring duct 8. A state where the table B 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. 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 formed 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. Can do.

  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 table A of the present embodiment includes the top plate 3, the leg base 1 attached to the corner of the top plate 3 and extending from the corner toward the inside of the top plate 3, and the leg base 1. And a caster 21 attached to the lower end of the leg 2. The caster 21 is directed downward by an operation applied to the operation unit 200. Is protruded, and the grounding member 20 is configured to be immersed by an operation in the reverse direction.

  The table A of this embodiment configured as described above can be freely moved on the floor in the XY direction, diagonal direction, or θ direction as shown in FIG. If the part 200 is operated, the moving function of the caster 21 is regulated by the grounding member 20 projecting downward and grounding as shown in FIGS. In this case, since the function of the caster 21 is regulated by grounding the grounding member 20 instead of locking the caster 21 itself, the grounding area can be increased and the caster 21 can be stably installed on the floor. Therefore, as shown by an imaginary line in FIG. 25, the tables A and A are brought into contact with each other, and the space between the top plates 3 and 3 is not particularly connected between the top plates 3 and 3 without being connected by a connecting member or a wiring duct. It is possible to effectively prevent the occurrence of a gap. Furthermore, if the operation unit 200 is operated in the reverse direction as shown in FIGS. 24B to 24A, the table A can be moved again by the casters 21. As described above, it is possible to immediately configure a large table from the single table A and separate it again into the single table A, and the layout flexibility can be dramatically increased.

  At this time, since the caster 21 stabilizes the grounding state by projecting the grounding member 20, even if the table A is lightened, the shape and size of the grounding surface, that is, the bottom surface of the grounding portion 202, An effective static friction force can be applied through the material and the like.

  In particular, since the leg base 1 for attaching the leg 2 to the top plate 3 spreads toward the inside of the top plate 3, the attachment state of the leg base 1 to the top plate 3 is stable, and consequently the attachment strength of the leg 2. In addition, it is possible to increase the ground contact distance between the legs 2 and 2 and to improve the stability of the ground contact state by bringing the leg 2 as close to the corner portion of the top plate 3 as possible.

  Further, as described above, the caster 21 according to the present embodiment is grounded at a position displaced in the horizontal direction from the center of the leg 2 and can swing freely around the center of the leg 2. Since the center is grounded at substantially the same position as the position where the wheel 213 is grounded in the side view shown in FIG. 24 as viewed from the direction orthogonal to the traveling direction of the caster 21, the center is grounded at the same position as the wheel 213. As shown, when the table A is adjusted to a position where it is desired to be fixed, the grounding member 20 can be grounded to the grounding position of the caster 21 as it is, and it is effective that the adjusted grounding state shifts when switching from the caster 21 to the grounding member 20. Can be prevented.

  Further, as shown in FIG. 23, the grounding member 20 is provided between the pair of wheels 213 and 213 so as to protrude and retract, and the grounding width is set smaller than the diameter M of the caster 21 as shown in FIG. Thus, since the grounding member 20 is hidden inside the caster 21, the appearance is improved and the grounding area can be sufficiently secured to some extent.

  Further, the lower end of the grounding member 20 is configured to come into contact with the floor and the anti-slip member 203a is provided at the lower end, so that the grounding state of the grounding member 20 can be stabilized.

  In addition to the above, in the table A of this embodiment, as shown in FIG. 8, four legs 2 are arranged at the four corners of the top plate 3 via the leg base 1, and two adjacent ones at required locations among them. Since the upper ends of the legs 2 and 2 are connected to each other by the frame 4 via the leg base 1, the leg base 1 can be used to effectively increase the rigidity of the top plate 3 as well as the mounting strength of the legs 2. In combination with an appropriate grounding state by the grounding member 20, it is possible to effectively prevent a problem or the like in which a gap is generated between the top plates 3 and 3 at the time of continuous connection shown in FIG.

  In particular, the table A of this embodiment has a gate-shaped leg constructed by connecting the upper ends of the two legs 2 and 2 with a frame 4 via a leg base 1 as shown in FIG. The body 2x is arranged in a pair at a position that supports the opposite edge of the top plate 3, and the legs 2x are further connected by a frame 4 so that the leg base 1 is used for the legs. The overall mounting strength and the rigidity of the entire top plate 3 can be effectively increased, and in combination with an appropriate grounding state by the grounding member 20, there is a problem in which a gap is created between the top plates 3 and 3 when connected as shown in FIG. Can be more effectively prevented.

  Although one embodiment of the present invention has been described above, the specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, as shown in FIG. 26, the grounding member 20 is almost directly below the leg 2 with respect to a caster 21 that is grounded at a position displaced in the horizontal direction from the center of the leg 2 and can swing around the center of the leg. It is also effective that the center is grounded. In this way, the caster 21 is movable when it is grounded. However, when the grounding member 20 is grounded, the load of the rod-like leg 2 is supported at the optimum position directly below. This configuration can be effective when it is desired to further increase the stability. What is necessary is just to comprise an operation member according to the principle of operation of FIG.23 and FIG.24.
