Description

  The present invention relates to a table in which the degree of freedom of arrangement of legs and frames and the mounting strength are increased.

  When a table is constructed by attaching legs to a top board, a leg base is generally used. As this type of leg base, for example, a flat leg base as disclosed in Patent Document 1 is generally used, and a leg is attached to the leg base and is attached to the lower surface of the top plate.

  However, even if the legs can be attached to the top board, the legs cannot be connected to each other, and the resistance against the falling moment of the legs cannot be increased.

  On the other hand, as a structure for directly connecting the legs, there is also known a structure in which a frame is bridged between the legs as shown in Patent Document 2, but when such a structure is adopted, the legs and the bridge are used. The position of the material is uniquely determined, and the degree of freedom regarding the setting of the ground contact position and the leg space is low.

  On the other hand, Patent Document 3 shows a structure in which a leg is attached to the base end of the leg base and a frame member that connects the legs to the extended end side extending from the base end. This is configured to deviate the positional relationship between the frame and the leg and further change the relative orientation.

  However, this leg base is only attached to the frame at the tip, and the mounting structure is also rotatably connected via a vertical axis. It is hard to say that it has made a sufficient contribution to support.

  Therefore, there is a demand for a leg base having a structure that can flexibly correspond to the relative positions of the legs and the frame member and can effectively increase the resistance against the leg falling moment.

  An object of the present invention is to provide a leg base having such a structure.

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

  That is, the table of the present invention is such that the lower surface of the corner of the top plate is supported by the legs via the leg base, and the leg base has a wide end on the base end side and a base end. A plurality of mounting members for forming a leg mounting portion on the lower surface of the side and attaching a mounting member for connecting with another leg base to the extending surface of the extending end by attracting the end surface of the mounting member A mounting surface is formed, and a plurality of leg bases having different arrangement directions are connected by a plurality of frames.

  If comprised in this way, a leg will be supported by the base material extended in a several different direction via a leg base, and since the end surface of a base material is drawn near and connected with the standing surface of a leg base, The falling moment can be effectively supported from a plurality of directions. Furthermore, since the mounting material mounting surface is formed on the extended extension side, the set number of mounting material mounting surfaces can be increased without difficulty, and the extension end side is connected to the center of the top plate. The extension end is suitably hidden under the top plate so that the appearance of the table can be kept good. In addition, since the mounting surface of the base material is taken out from the position of the legs, the dimensions of the base material become the end dimensions compared with the case where the legs are directly connected, and the bending rigidity of the base material and thus the mounting strength of the legs can be effectively increased. Can do. As described above, according to the present invention, it is possible to flexibly cope with the relative positions of the leg and the frame member, and it is possible to effectively increase the resistance against the leg falling moment.

  In order to ensure the strength of the mounting surface even if the leg base is light, the leg base has a structure that forms a closed peripheral wall that includes the mounting surface and connects the peripheral wall with the bottom wall. Thus, it is desirable that the upper surface of the peripheral wall is a top plate support surface.

  In particular, in order to increase the resistance to the leg collapse load, a part of the peripheral wall is constituted by a pair of opposing walls, and the top plate mounting holes are respectively provided in the narrow part and the largest part of the distance between the opposing walls. It is desirable to provide.

  Moreover, in order to ensure the frame mounting strength, it is preferable that the frame mounting surfaces of adjacent leg bases are parallel.

  In the case where the leg base has a closed hollow shape, in order to appropriately attach and detach the frame member, a transparent window is provided on an elevational surface of the peripheral wall other than the frame attachment surface. It is effective to form a connection tool insertion / extraction path for pulling and fastening the frame member between the frame mounting surface and the corresponding member mounting surface.

  In this case, in order to effectively close the transparent window, it is preferable that an option member mounting surface is formed on the vertical surface of the peripheral wall where the transparent window is provided.

  In addition, in order to appropriately fasten the frame member to the leg base outside the leg base, the vertical surface of the peripheral wall of the leg base with respect to the frame member mounting direction is located at or near the vertical surface provided with the frame member mounting surface. An inclined screw hole is provided on the side opposite to the top plate, and a screw inserted obliquely through the screw seat from the frame member is screwed into the screw hole and tightened to draw the frame material to the leg base for fastening. It is preferable.

  In order to make it possible to rationally attach a leg of the required strength to the same position on the leg base according to the purpose and application, a leg having a non-circular mounting hole is fitted on the lower surface of the leg base. And a second leg fitting for fitting a leg having a non-circular mounting hole larger than the leg in a pair with the first leg fitting part. It is desirable to project the joint at adjacent positions.

  Since the present invention has the above-described configuration, it is possible to obtain a degree of freedom in arrangement between the leg attachment portion and the frame attachment portion through the leg base, and the leg and the frame material are appropriately arranged at required positions. In addition, it is possible to provide a table that effectively increases the resistance against a leg falling moment by connecting a plurality of frames in different directions to the wide extending end side of the leg base.

Used as a member

  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 table A of the present embodiment is such that the lower surface of the corner of the top plate 3 is supported by the leg 2 via the leg base 1, and the leg base 1 extends to the base end side. The end side is widened, the leg attachment portion 15 is formed on the lower surface on the base end side, and the frame member 4 that connects the other leg base 1 is formed on the end surface of the extended end side. Since a plurality of mounting members mounting surfaces 12a for attracting and mounting 4a are formed and the plurality of leg bases 1 and 1 having different arrangement directions are connected by a plurality of mounting members 4, the legs 2 are connected via the leg bases 1. It will be supported by a plurality of support members 4 extending in different directions, and the end surface 4a of the support member 4 is drawn and connected to the vertical surface of the leg base 1, so that the falling moment of the legs 2 can be effectively prevented from two directions. Can be supported. Furthermore, since the mounting member mounting surface 12a is formed on the extended extended end side, the set number of the mounting member mounting surface 12a can be increased without difficulty two as shown in the illustrated example, Moreover, the extension end side is directed to the center side of the top plate 3 so that the extension end can be suitably hidden so as to sink under the top plate 3 and the appearance of the table A can be kept good. Furthermore, since the mounting member mounting surface 12a is taken out from the position of the leg 2, the size of the mounting member 4 can be reduced compared to the case where the legs 2 and 2 are directly connected to each other. The mounting strength can be effectively increased. As described above, according to the present embodiment, it is possible to flexibly cope with the relative position of the leg 2 and the frame member 4, and the resistance against the falling moment of the leg 2 can be effectively increased.

  In particular, the leg base 1 forms a closed peripheral wall 1x including a frame attachment surface 12a, and the peripheral wall 1x is connected by a bottom wall 14, and the upper surface of the peripheral wall 1x is a top plate support surface. Therefore, even if the leg base 1 is made light, it is possible to effectively prevent the frame mounting surface 12a from opening.

  In this case, a part of the peripheral wall 1x is constituted by standing walls 11, 11 (12, 12) which are a pair of opposing walls, and the top plate mounting holes are respectively provided in the narrow part and the largest part of the distance between the opposing walls. Since 10a is provided, the fall load of the leg 2 can be effectively supported in each attachment location between the leg base 1 and the top plate 3.

  In particular, since the frame attachment surfaces 12a and 12a of the adjacent leg bases 1 and 1 are parallel, it is easy to ensure the frame attachment strength.

  In addition, a through window 11b is provided on an elevational surface of the peripheral wall 1x other than the frame attachment surface 12a, and a connection for pulling and fastening the frame material 4 between the through window 11b and the corresponding frame attachment surface 12a. Since the screw insertion path L, which is a tool, is formed, even when the leg base 1 is closed to ensure strength, the plurality of frames 4 can be attached and detached appropriately.

  If the optional member mounting surface 11d is formed on the vertical surface of the peripheral wall 1x where the transparent window 11b is provided, there is no need to obtain the optional member mounting position on the top plate 3, and the leg base 1 is present. Optional members can be attached freely. Moreover, since the transparent window 11b is closed when the optional member is attached, the appearance of the leg base 1 can be kept good.

  Then, a first leg fitting portion 15a for fitting the leg 2 having the non-circular mounting hole 21 on the lower surface of the leg base 1, and the first leg fitting portion 15a are paired with the first leg fitting portion 15a. Since the second leg fitting part 15b for fitting the leg 102 having the non-circular mounting hole 121 larger than the leg is fitted at the adjacent position, the leg base 1 The leg 2 having the necessary strength can be appropriately attached to the same position according to the purpose and application.

  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, in order to make it possible to attach a frame from the outside of the leg base, as shown in FIG. 22, on the peripheral wall 1x of the leg base 1, the frame is mounted on or near the upright surface 12 provided with the frame attachment surface 12 a. While the screw hole 12x inclined with respect to the material mounting direction (X direction) is provided, the opening 4x and the slit 4y are provided at the opposite positions of the frame member 4 so that the screw seat 4z made of a thick plate is connected to the opening edge of the opening 4x and the slit 4y. The base material 4 is drawn to the leg base 1 by screwing the screw v3 inserted into the screw seat 4z from an oblique direction into the screw hole 12x of the leg base 1 and tightening. May be fastened. In this way, even if the leg base 1 is closed or a state in which a plurality of frames 4 are attached to the leg base 1, any frame 4 can be appropriately attached and detached. It becomes.
