With such a configuration, the leg base 1 has a lower end 7a on which the top plate is used. It becomes easy to put the leg in and out of the leg space without catching the leg. Moreover, since the footrest board 4 is inclined in the same direction, it is possible not only to prevent the placed foot from slipping toward the counter-use end 7b of the top plate, but also to encourage the user to lean backwards. It is possible to provide a comfortable desk work environment while suppressing In addition, since the footrest board 4 is disposed in an inclined posture between the leg bases 1 in a state in which the upper surfaces 1a of the left and right leg bases 1 protrude above the upper surface 4a of the footrest board 4, the footrest can be Even if the user's foot slides laterally on the board 4, it is caught by the leg base 1 when it reaches the side end of the footrest board 4, so that the user's foot is prevented from protruding outside the leg base 1.例文帳に追加can also

Further, in this furniture T with a top plate, since the peripheral wall surface 32 of the rear horizontal frame 3 and the peripheral wall surface 53a of the vertical frame 5 are rigidly connected in a state of surface contact, the length of the vertical frame 5 can be adjusted. Furthermore, it is possible to set the length as long as possible, and it is possible to secure a wide joining area by welding or the like. Therefore, a frame structure with high rigidity can be constructed.

Furthermore, the front horizontal frame 2 located on the top plate use end side 7a is arranged at a position lower than the rear horizontal frame 3 located on the top plate non-usage end 7b side, and one end of the vertical frame 5 The end face 5a is rigidly connected to the rearward peripheral wall surface of the front horizontal frame 2, and the peripheral wall surface 53a at the other end of the vertical frame 5 is rigidly connected to the downward peripheral wall surface 32 of the rear horizontal frame 3. Therefore, a three-dimensional frame structure having high rigidity can be constructed. That is, according to such a configuration, the vertical frame 5 and the front and rear horizontal frames 2 and 3 not only form a frame structure along the inclined first plane, but also allow the vertical frame 5 to extend horizontally on the second plane. Since both sides of the front and rear horizontal frames 2 and 3 are rigidly connected to the outer wall 12 of the leg base 1, respectively, the vertical frame 5 and the rear horizontal frame are arranged in a side view. 3 and the leg base 1 form a triangle. Therefore, compared to a structure in which both end surfaces of the vertical frame 5 are rigidly connected to the rear-facing peripheral wall surface 24 of the front horizontal frame 2 and to the forward-facing peripheral wall surface 33 of the rear horizontal frame 3, respectively, and these are joined in a plane, Rigidity against the action of bending the vertical frame 5 in the vertical direction is increased. In other words, a triangular frame structure is realized when viewed from the side, and a structure that is less likely to be distorted than a one-sided frame structure can be constructed. Therefore, it is possible to effectively suppress swinging of the leg support 6 and the top plate 7 supported by the vertical frame 5, and to improve the overall rigidity reasonably.

In addition, since a gap S is formed between the front horizontal frame 2 and the floor surface F to allow the feet of the user to enter, the front horizontal frame 2 can be moved as much as possible. Even if the rigidity of the frame is increased by locating it on the use end 7a side, the space for the lower limbs can be effectively secured, resulting in good usability. In particular, the vertical frame 5 is rigidly connected to the rear-facing peripheral wall surface 24 of the front horizontal frame 2 so that the vertical frame 5 does not protrude downward from the lower end of the front horizontal frame 2. There is no interference with the vertical frame 5 even if the foot is inserted below and moved left and right.

Furthermore, in this embodiment, each leg base 1 is a hollow body having an inner wall 11 and an outer wall 12, and each lateral frame 2, 3 is attached to the inner side of the corresponding leg base 1 at both ends. Since the wall 11 is passed through and rigidly connected to the outer wall 12 to form a square pipe, the strength of the connection between the left and right leg bases 1 and the front and rear lateral frames 2 and 3 is reasonably increased. be able to.

In this embodiment, the vertical frame 5 and the leg support 6 are configured to be screwed in an orthogonal state, and the end surface of the leg base 1 on the side opposite to the use end 7b, that is, the rear end surface 1b is attached to the leg support 6. Since they are formed parallel to each other, it is easy to assemble using the storage box BX as described above. That is, according to such a configuration, when the leg base 1 is erected with the rear end surface 1b in contact with the floor surface F, the vertical frame 5 is vertically erected. Therefore, if the thickness t of the storage box BX is properly set in advance, the leg struts 6 lying on the storage box BX can be easily bolted to the vertical frame 5. - 特許庁Therefore, the assembly work after carrying in is easy, and it is suitable for use at home or the like.

Furthermore, in this embodiment, the operation cable 82 extending from the operation body 71 and the drive cable 81 extending from the upper end portion of the leg support 6 are bundled at the assembly position P facing the one end surface 9a of the controller 9, and the controller 9, respectively. Therefore, the position where the operation cable 82 and the drive cable 81 are assembled is clear, and the wiring work does not get lost, and the lower part of the top plate does not become cluttered. Moreover, since both cables 81 and 82 are bound by the common binding tool 83 at the collective position P, the number of man-hours required for the binding work can be reduced compared to the case where each cable is separately fixed to the top plate at many positions. In addition, the types and number of components for holding wiring can be reduced reasonably. In addition, one of the cables, which tends to be long, that is, in this embodiment, the drive cable 81 is clamped in the middle between the controller 9 and the top plate 7. Alternatively, it is possible to effectively prevent these cables 81 and 82 from swaying or sagging simply by binding with a common binding tool and a small number of auxiliary binding tools.

In particular, as in this embodiment, the single column type leg support 6 is fixed to the central portion of the top plate 7, and the operation body 71 is located near one side edge 7d of the top plate 7 on the side of the use end 7a. In the case where the controller 9 is provided on the non-use end 7b side of the top plate 7, as described above, the collective position P is set near one side of the top plate 7 on the non-use end 7b side. Then, an operation cable 82 extending from the operation body 71 is guided to the assembly position P, and a drive cable 81 extending from the leg post 6 toward the other side edge 7 e of the top plate 7 is connected between the top plate 7 and the controller 9 . If they are guided to the assembly position P by passing between them, the above effects can be remarkably exhibited. That is, according to this arrangement, the operation cable 82 directed from the operation body 71 to the collective position P can be arranged substantially linearly, and the drive cable 81, which tends to be long, led out from the leg strut 6 can be routed by the controller. It can be stably held by being sandwiched between 9 and top plate 7 . Therefore, even when only a single common binding member 83 is used, the cables 81 and 82 can be arranged under the top plate 7 in an orderly and stable manner.

The present invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the present invention.

For example, the leg support is not limited to the single-post type, and the top plate may be supported by a plurality of leg supports that expand and contract in synchronism.

The operating body in the illustrated example is of a lever type, and when the lever is operated upward, an operation signal is output in the direction in which the leg support is extended, and when the lever is operated downward, the leg support is contracted. Although the operation signal in the direction to move is output, it is not necessarily limited to such a configuration. In short, any operation body can be used as long as it can selectively output an operation signal for raising the tabletop or an operation signal for lowering the tabletop by the user's operation. may

Any controller may be used as long as it can operate the electric actuator forward and backward based on the operation signal from the operation body. Also, the configuration and arrangement positions of the connection terminals for connecting the operation cable, the drive cable, and the power cable are not limited to those in the illustrated example.

In addition, the above-mentioned common binding tool includes a band portion for detachably binding the operation cable and the drive cable in a wound state, and a mounting plate portion for attaching the band portion to the lower surface of the top plate. It is not necessarily limited to such a thing. In addition, instead of detachably binding the operation cable and the drive cable in a wound state with a common binding tool, the binding tool for the operation cable and the binding tool for the drive cable are brought close to the assembly position and separated. You may make it provide.

Furthermore, in the illustrated embodiment, the cable guide groove is provided on the upper surface of the controller, but the cable guide groove may be provided on the lower surface of the top plate. Alternatively, cable guide grooves may be provided on both the upper surface of the controller and the lower surface of the top plate. In this case, the lower half of the drive cable can be fitted into the cable guide groove of the controller, and the upper half of the drive cable can be fitted into the cable guide groove of the top plate. In this way, it is also possible to position the controller with respect to the top plate by means of the drive cable. The cable sandwiched between the controller and the top plate is not limited to the drive cable, and may be the operation cable.

The manner in which the power cable that supplies power to the controller is guided is not limited to the one shown in the figure, but if it is constructed as shown in the figure, an unreasonable force will act when the leg support is contracted or extended. It is possible to guide the power cable in an attractive and orderly manner without having to remove the cable.

In addition, various modifications may be made within the scope of the present invention.
