Description

  The present invention relates to a desk suitably used in an office or the like, and an office configuration system using a plurality of desks.

  In the past, various office spaces, such as office spaces where individual workers can concentrate on their work, and office spaces suitable for group communication such as meetings and meetings where multiple people gather, There have been developed desks whose layouts can be changed as appropriate according to organizational changes or uses and purposes, and an office configuration system using a plurality of such desks.

  As an example, there is a desk that can be arranged independently on the floor and can form various office spaces by allowing workers to move freely (see, for example, Patent Document 1).

Further, as another example, a screw or insertion portion provided directly or indirectly at one end of the top plate, with a plurality of screw holes or fitting holes formed at a predetermined pitch in the top plate support unit provided on the floor surface And a desk in which the other end of the top plate is supported by a leg that contacts the floor surface. This desk is configured such that the mounting position of the top plate relative to the top plate support unit can be changed by changing the screw hole or the fitting hole for screwing or fitting the screw or the insertion portion.
Japanese Patent Laid-Open No. 9-299167

  However, in the former case, each desk can move freely on the floor independently, so that each office space and the whole office easily fall into a cluttered state at the time of layout change or after layout change, There has been a problem that the office space and offices where layout changes are frequently performed are not suitable for constituting offices.

  On the other hand, in the latter case, when changing the mounting position of the top plate relative to the top plate support unit, the screw or insertion portion provided at one end of the top plate and the screw hole or the fitting hole are screwed or fitted. Once the screw is released, the screw or insertion part must be screwed or fitted again into a different screw hole or fitting hole. Such work is cumbersome and, in some cases, not requested by a contractor. There has been a problem that the layout cannot be changed easily and accurately.

  The present invention has been made paying attention to such a problem, and a main purpose thereof is a desk capable of easily and accurately changing the layout without disturbing the order of the office space and the entire office, and the like. Is to provide an office configuration system using a plurality of desks.

  That is, the desk of the present invention includes a base that extends in a predetermined direction, a movable support that is movably supported with respect to the base, and a top plate that is supported by the movable support. To do.

  If this is the case, the range of movement of the top plate supported by the movable support is regulated by the base, and it is possible to prevent the office space and the entire office from becoming cluttered when the layout is changed or after the layout is changed. Therefore, the office space where the layout is frequently changed and the office are excellently qualified. In addition, since the movable support is movable with respect to the base, the screwed state or the fitted state between the screw or the insertion portion and the screw hole or the fitting hole is once released every time the layout is changed as in the prior art. The operation of screwing or fitting the screw or the insertion portion into a different screw hole or fitting hole again becomes unnecessary, and the worker can easily and accurately change the layout without relying on the contractor.

  Here, the “top plate supported by the movable support” is a concept including “a top plate supported by being placed on the movable support”.

  In addition, another desk according to the present invention includes a base extending in a predetermined direction, a movable support supported to be movable with respect to the base, and a top plate supported by the movable support, The movable supporter is movable with respect to the base together with the top plate while supporting the top plate.

  Even in such a case, not only can the effect substantially the same as that of the desk described above be obtained, but also the top plate is removed from the movable support when the relative arrangement position of the top plate with respect to the base is changed. Or the operation | work of reattaching becomes unnecessary and becomes the thing excellent in operativity. In addition, the “top plate supported by the movable support” is a concept including “a top plate supported by being placed on the movable support” as described above.

  In particular, if the top plate is supported by the movable support so as to be able to turn horizontally, the top plate has a posture in which the longitudinal direction is substantially parallel to the longitudinal direction of the base, or the longitudinal direction is the longitudinal direction of the base. The relative angle / posture of the top plate with respect to the base, such as the posture substantially orthogonal to the base, can be selected, and the number of selectable layout variations increases.

  Further, if the top plate includes a leg that supports a part different from the part supported by the movable support, and a movable body that can move on the floor is provided at the lower end of the leg, the layout When changing, the moving body moves (slids) on the floor surface, so that it can be smoothly moved along the base without lifting the top plate.

  In order to smoothly and surely move the movable support relative to the base, the base is provided with a guide portion for guiding the movement of the movable support, and the movable support is guided by the guide portion. A guided portion may be provided. In this case, as a preferred embodiment, the guide portion may be a rail formed along the extending direction of the base, or the guided portion may roll along the rail formed by the base. The aspect which is provided with the rolling element is mentioned.

  Further, if a fixed support body that is supported so as not to be slidable with respect to the base and a fixed top plate supported by the fixed support body are provided, the movable support body and the fixed support body are attached to the common base. By supporting the movable top plate and the fixed top plate on each support body, the desk has a movable top plate and a fixed top plate, so layout changes frequently occur within a single desk. Therefore, it is possible to form an area that can correspond to an environment that is changed and an area that can correspond to an environment where the layout is not frequently changed, and can flexibly cope with various layouts.

  Here, the fixed support body only needs to be supported so as not to be slidable with respect to the base. For example, the fixed support body is fixed to the base by screwing or the like, or a part thereof is brought into contact or pressure contact with the base. It may be movable in the state. That is, it is preferable that the fixed support is not positively moved with respect to the base but can be moved with respect to the base mainly when the base is attached or detached.

  In order to create a desk that can handle various work styles, with one area as a work space where the layout can be freely changed and the other area as a work space where the layout cannot be changed, the base must be in the longitudinal direction. A pair of upright surface portions facing each other along, a guide portion for guiding the movement of the movable support body on one of the upright surface portions, and an attachment portion for mounting the fixed support body on the other upright surface portion May be provided. In this case, if the guide part and the mounting part are rails having the same shape, the rails can be shared, and the structure of the base can be simplified compared to the case where the guide part and the support part have different shapes. To contribute.

  In addition, if the fixed top plate is supported by the fixed support in a cantilevered manner, a leg for supporting the fixed top plate is not necessary, and a wide leg space for the fixed top plate can be secured.

  In addition, the office configuration system of the present invention is characterized in that it uses a plurality of desks having the above-described effects, and the layout can be changed in accordance with the contents of work.

  If it is such an office configuration system, a highly autonomous environment or a highly interactive environment where the office can be concentrated and changed by changing the position / posture of the top plate with respect to the base as required It can be created freely, and office spaces and offices corresponding to various occupations and job forms can be easily formed. In addition, since the layout is based on the base of each desk, it is possible to optimize each office space and the entire office without falling into a cluttered state. And the improvement of the work efficiency of each worker who works in the office space or office formed by such an office configuration system can make a great contribution to the improvement of productivity not only for each worker but also for the entire office.

  As described above, according to the present invention, since the position change and the posture change of the top board are performed with reference to the base, each office space and the entire office can be changed without falling into a cluttered state. While maintaining the order at a certain level, the worker can easily and accurately change the layout without relying on the contractor.

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

The guide portion 2B is configured. The relative position of the option member with respect to the base 2 can be changed by sliding the option member along the option member guide portion 2B. In the present embodiment, as an optional member, a desktop panel DTP and a storage shelf ST integrally provided or a task light TL is applied. Each guide portion 2A, 2B is formed from one end of the base 2 to the other end. Further, end caps 2C are detachably attached to both ends of the base 2, respectively.

  The base support 3 supports both ends of the base 2. The base support 3 has, for example, a prismatic shape having a depth dimension substantially the same as the short dimension of the base 2, and a plurality of desks 1 are continuously arranged so that each base 2 is continuous in the longitudinal direction. In the office configuration system according to the present embodiment, the auxiliary base support 3a is integrated with the base support 3 positioned at both ends as viewed from the entire office configuration system by a suitable means among the plurality of base supports 3. To achieve good independence and stability of the entire office configuration system.

  As shown in FIG. 1, the movable support body 4 includes a top plate receiving portion 31 that supports the top plate 5a (or 5b) and a guided portion 42 that is guided by the top plate guide portion 2A. It is. The top board receiving part 31 supports the predetermined area | region of the one end part side of the top board 5a (or 5b) directly or indirectly from the downward direction. The guided portion 42 includes an insertion portion that can be inserted into the rail 2a and a rolling element (not shown) that is provided at the distal end portion of the insertion portion and can roll along the rail.

  Each of the top plates 5a and 5b is a plate-like plate having a substantially gourd shape in plan view (an elliptical shape with a central portion confined) or a substantially rectangular shape in plan view, and the maximum longitudinal dimension is substantially the same as the longitudinal dimension of the base 2 or It is set small. And the one end part of the top plates 5a and 5b is each supported by the movable support body 4 so that horizontal rotation is possible. As a specific mode for pivotally supporting the top plates 5a and 5b on the movable support body 4, for example, there is a simple uniaxial structure using a single shaft. In the present embodiment, the lower surfaces of the top plates 5a and 5b are set so as to be positioned slightly above the upper surface portion 22 of the base 2, and the top plates 5a and 5b are turned when the top plate 5a or 5b is turned horizontally. And the base 2 are prevented from interfering with each other. Further, a part of the top plates 5a and 5b and the upper surface portion 22 of the base 2 are overlapped with a predetermined distance in the height direction, but a part of the top plates 5a and 5b is formed on the upper surface portion 22 of the base 2. The option member guide portion 2B is set so as not to overlap with the option member guide portion 2B, so that part of the option member guided by the option member guide portion 2B is prevented from interfering with part of the top plates 5a and 5b.

  The leg 6 includes a leg main body 61 that directly supports the other ends of the top plates 5a and 5b, and a caster 62 that is a moving body of the present invention provided at the lower end of the leg main body 61. In addition, it mentions that the top plate 5a or 5b with both ends supported by the movable support 4 or the leg 6 is set to be parallel to a flat floor surface in a normal use state. Needless to do.

  The desk 1 having such a configuration can change the relative positions of the top plates 5a and 5b with respect to the base 2 by sliding the top plates 5a and 5b along the longitudinal direction of the base 2. The top plate 5a with respect to the base 2, such as a posture in which the longitudinal direction of the base plates 5a and 5b is substantially parallel to the longitudinal direction of the base 2, or a posture in which the longitudinal direction of the top plates 5a and 5b is substantially perpendicular to the longitudinal direction of the base 2. 5b can be selected as appropriate.

  In the office configuration system according to the present embodiment in which two such desks 1 are connected in series, as shown in FIGS. 1 and 2A, the top plate 5a or 5b is based on the longitudinal direction thereof. 2 and the top plates 5a and 5b are positioned on the side of the base 2 that is separated from the other base 2 (the anti-connection end side). Can be set to a first layout that forms an office space and an office where workers can work in a concentrated manner. In FIG. 2, the base 2 is provided with a pattern. Further, as shown in FIG. 2B, the top plates 5a and 5b are in a posture in which the longitudinal direction thereof is substantially orthogonal to the longitudinal direction of the base 2, and the top plates 5a and 5b are arranged in the base 2. By positioning on the side connected to the other base 2 (connection end side), it is possible to set a second layout that workers using the top plates 5a and 5b can face, and this second layout is It forms a working space and office where workers can work while communicating with each other. Further, as shown in FIG. 2 (c), the top plates 5a and 5b are arranged so that the longitudinal direction thereof is substantially parallel to the longitudinal direction of the base 2, and the top plates 5a and 5b are arranged along the longitudinal direction. Thus, the workers using the top plates 5a and 5b can be set to the third layout in which they are arranged side by side. The third layout forms an office space and an office where workers can communicate with each other while concentrating. In addition, by moving the option member along the base 2 using the option member guide portion 2B corresponding to each layout, it is possible to form an office space and an office excellent in workability. In this manner, a layout appropriately selected from at least three patterns of layouts can be set. In FIG. 1 and FIG. 2, a partition P that partitions the work space of each worker is arranged. In the present embodiment, an attachment member Pa for attaching the partition P to the base 2 is provided in a part of the partition P (see FIG. 1). You may employ | adopt the layout which does not arrange | position the partition P by selection of a worker. Further, when the desks 2 are integrally connected to each other, connection means (not shown) for connecting one base 2 and the other base 2 together may be used. As the connecting means, for example, one using an engaging portion provided in each end cap and capable of mutual engagement (concave engagement or hook engagement) with the adjacent end cap, or provided at the end of the base and adjacent. Examples thereof include those using an engaging portion capable of mutual engagement (concave engagement or hook engagement) with the end portions of the base, and those using a fastening member such as a screw for fastening the bases 2 to each other.

  When changing the layout from any of the above layouts to another layout, the worker himself or herself moves the tabletops 5a and 5b along the base 2 or horizontally rotates the tabletops 5a and 5b with respect to the base 2. By applying the operating force, the top plates 5 a and 5 b can be set at a desired position or posture with respect to the base 2. In particular, in the present embodiment, since the casters 62 are provided on the legs 6 that support the other ends of the top plates 5a and 5b, the top plates 5a and 5b can be slid relative to the base 2 with a relatively light force. It can be swiveled horizontally.

  Such an office configuration system using a plurality of desks 1 can be set and changed in various layouts according to the business form and work contents of each individual or organization as shown in FIG. It is. In each layout shown in each drawing, the relative position / relative angle orientation of the top plate 5 with respect to the base 2 can be easily grasped from the drawings, and thus detailed description for each layout is omitted.

  The layouts shown in (A-1) to (A-8) shown in FIGS. 3 to 5 are, for example, various layouts suitable for office spaces and offices for resident workers (for example, managers such as managers). It is.

  The layouts shown in (B-1) to (B-5) shown in FIG. 6 and FIG. 7 are various layouts suitable as a work space and office for a call center that performs reception work by a telephone line or a net line, for example. .

  The layouts shown in (C-1) to (C-7) shown in FIGS. 8 to 10 are various layouts suitable as office spaces and offices for planners and consultants, for example.

  The layouts shown in (D-1) to (D-3) shown in FIG. 11 are various layouts suitable for office spaces and offices for sales departments and consultation rooms with business partners, for example.

  The layouts shown in (E-1) to (E-3) shown in FIG. 12 are various layouts suitable as office spaces and offices that require group communication such as meetings, group work, or presentations.

  In addition, in FIGS. 3-12, as a top view, in addition to the gourd shape or the rectangular shape, the top plate has a polygonal shape on one end side and a partial arc shape on the other end side, or an L-shape. Or a square shape is applied, and all the top plates are denoted by reference numeral “5” regardless of the difference in shape. 3 to 12 are mainly intended to show the position and posture of the top plate 5 with respect to the base 2, so that the movable support and the leg are omitted, and each base 2 is similar to FIG. A pattern is attached.

  1 and 2 exemplify a mode in which a single base 2 is provided with a single top plate 5a (or 5b). However, in FIGS. The aspect provided with the several top plate 5 with respect to the single base 2 according to etc. is illustrated. Specifically, the aspect which arrange | positions the top plate 5 via the movable support body 4 in the site | part (standing surface part 21 shown in FIG. 1) which opposes along the longitudinal direction among the bases 2, respectively, and one standing surface part 21. 3 illustrates a mode in which a plurality of top plates 5 are disposed via the movable support 4 (see FIG. 3A-1). The movable support 4 is detachably supported by the base 2 (for example, the movable support 4 can be inserted into and removed from the guide portion 2A with the end cap 2C removed from the end of the base 2). For example, the number of the top plates 5 for the single base 2 can be appropriately selected and attached by the user himself / herself. Moreover, as shown to FIG. 4 (A-1), the same figure (A-2), etc., it is also possible to set the top plate 5 in the position straddling the adjacent base 2. FIG. On the other hand, as shown in FIG. 9 (C-5), FIG. 9 (C-6), etc., it is possible to adopt a layout in which the base 2 to which the top plate 5 is not attached is present. Further, as shown in FIGS. 3A-3, 6B-2, etc., a layout in which the desks 1 are opposed to each other so that the bases 2 face each other in the short direction can be adopted.

  Further, as shown in FIG. 7 (B-5), FIG. 8 (C-2), etc., a layout in which the turning angle of the top 5 with respect to the base 2 is set to an angle other than 90 degrees (for example, 45 degrees) is adopted. It is also possible to do.

  As described above, the desk 1 according to this embodiment includes a base 2 extending in a predetermined direction, a movable support 4 supported so as to be movable with respect to the base 2, and a top plate 5 supported by the movable support 4. (5a, 5b), the top plate 5 (5a, 5b) supported by the movable support 4 can be moved along the base 2, and the layout can be easily changed. In addition, the movement range of the top board 5 (5a, 5b) is restricted by the base 2, so that the working space based on the base 2 and the order of the entire office can be maintained. In addition, since the movable support 4 is slidable with respect to the base 2, the screw or insertion portion and the screw hole or the fitting hole are screwed or fitted each time the layout is changed as in the prior art. The work of once releasing and screwing or fitting the screw or the insertion portion into a different screw hole or fitting hole again becomes unnecessary, and the worker can easily and accurately change the layout without relying on the contractor.

  In particular, since the top plate 5 (5a, 5b) is supported by the movable support 4 so as to be able to turn horizontally, only the direction of the top plate 5 (5a, 5b) is changed without changing the installation direction of the desk 1 itself. The number of layout variations that can be selected is dramatically increased.

  In addition, since the casters 62 are provided on the legs 6 that support the other end of the top plate 5 (5a, 5b), the casters 62 slide on the floor surface when the layout is changed. The top plate 5 (5a, 5b) can be smoothly horizontally moved or turned with respect to the base 2 without lifting (5a, 5b).

  Furthermore, the base 2 is provided with a top plate guide portion 2A for guiding the movement of the movable support body 4, and the movable support body 4 is provided with a guided portion 42 guided by the top plate guide portion 2A. The movable support 4 can be accurately moved with respect to the base 2. In particular, the top plate guide portion 2A is the rail 2a formed along the extending direction of the base 2, and the guided portion 42 includes rolling elements that can roll along the rail 2a. The top plate guide portion 2A and the guided portion 42 can be realized with a simple structure, which contributes to cost reduction.

  Further, in the office configuration system using a plurality of desks 1 according to the present embodiment, the worker moves the top board 5 (5a, 5b) with respect to the base 2 as the scale increases or the organization changes. By moving or horizontally turning, a personal work area or a joint work area can be appropriately formed, and a highly autonomous environment or a highly interactive environment that allows concentrated work to be performed as required. Can be created. Moreover, the layout can be changed without disturbing the order, and the work space and the entire office can be optimized. And the improvement of the work efficiency of the office space formed by such an office configuration system and the worker who works in the office can make a great contribution to the improvement of the productivity of not only the worker unit but also the whole office.

  Further, in the office configuration system using the desk 1 and the desk 1 according to the present embodiment, as shown in FIG. 13, a fixed top 5 </ b> X whose relative position cannot be changed can be attached to the base 2.

  The fixed top 5X is supported by one or a plurality of fixed supports 4X that are supported by the base 2 so as not to slide. In the present embodiment, as the fixed top plate 5X, a substantially rectangular shape in plan view having a longitudinal dimension substantially the same as the longitudinal direction of the base 2 is applied. And the fixed support body 4X is integrally attached to each side edge part of this fixed top plate 5X, and these fixed support bodies 4X are supported by the base 2, thereby the load applied to the fixed top plate 5X is fixed to the fixed support body 4X. And I am trying to receive it at the base 2. That is, the fixed top plate 5X is cantilevered by the base 2 via the fixed support 4X.

  The fixed support 4 </ b> X can be attached to the rail 2 a provided on the standing surface portion 21 of the base 2. That is, the rail 2a serves as an “attachment portion” for attaching the fixed support 4X. The fixed support 4X is appropriately fixed in a state where a mounting portion provided at one end is inserted into the rail 2a. In the present embodiment, such a fixed support 4X is provided on each side of the fixed top 5X, and the fixed top X is supported only by these fixed supports 4X.

  Thus, in this embodiment, the movable support body 4 and the fixed support body 4X are set to be attachable to the base 2 using the rail 2a having the same shape and the same structure. FIG. 13 illustrates a mode in which the base 2 side end surface portion of the fixed top plate 5X is brought close to or in contact with the standing surface portion 21 of the base 2, but the base 2 side end surface portion of the fixed top plate 5X is illustrated. You may employ | adopt the aspect spaced apart from the standing surface part 21 of the base 2 by the predetermined dimension. Moreover, in FIG. 13, the chair arrange | positioned linked | related with the fixed top plate 5X is abbreviate | omitted.

  Thus, the desk 1 according to the present embodiment includes the fixed support 4X that is supported so as not to be slidable with respect to the base 2, and the fixed top plate 5X that is supported by the fixed support 4X. Therefore, as shown in FIG. 13, in the single desk 1 area, it is possible to form a layout changeable area and a layout nonchangeable area using the common base 2, It is possible to cope with both an environment where layout changes are frequently performed and an environment where layout changes are not performed.

  Furthermore, by making one area a work space whose layout can be freely changed with the base 2 as a boundary, and making the other area a work space not suitable for layout change, various work styles can be flexibly dealt with.

  In particular, it is possible to move the movable support 4 with respect to the base 2 and mount the fixed support 4X with respect to the base 2 using the rail 2a having the same shape. A mode in which the layout can be freely changed and the other area is a workspace in which the layout cannot be changed, a mode in which any area is a layout in which the layout can be freely changed, or a mode in which any area is a layout that cannot be changed, When a desired mode is selected or changed from these modes, the common rail 2 can be used without replacing the rail 2.

In addition, since the fixed top plate 5X is supported by the fixed support 4X in a cantilevered manner, a leg is not required, and a wide leg space below the fixed top plate 5X can be secured.

In this connected state, the hinge shaft H <b> 1 of the hinge mechanism H is positioned at a position away from the support region by the priority support portion 412. The hinge shaft H1 is prevented from coming off by a large-diameter head, a fastener such as an E-ring, or caulking.

  Next, the method of using the desk 1, particularly, the operation and action when the top plate 5 is slid along the base 2 together with the movable support 4 or when the slide movement is restricted will be described.

  First, when the switching mechanism 4E of each switching unit 422 is switched from the movement restricted state (see FIGS. 17 to 20) to the movement allowed state (see FIGS. 22 to 25), the knob 4241a of the slide operation lever 4241 is gripped. The slide operation lever 4241 is rotated around the slide operation lever shaft 4242 in the direction of arrow A in FIGS. As the slide operation lever 4241 rotates, the link interlocking body 4231 pressed against the cam surface 4241b of the slide operation lever 4241 moves from the reinforcing body 4212 toward the main body portion 4211 (FIGS. 24 and 25). reference). Then, the links 4G1 and 4G2 of the switching units 422 in which the base end portions 4G1b and 4G2b are connected to the link interlocking body 4231 are interlocked and rotated around the link shaft 4232, respectively. In each switching unit 422, the upper link 4G1 and the lower link 4G2 facing each other in the height direction rotate about a common link shaft 4232, so that the upper link 4G1 is connected via the upper roller support 4Ca. The upper rolling element 4C provided at the distal end 4G1a moves toward the opening-side standing wall 21a of the upper rail groove 21, and the adjustment link 4G21 and the lower roller support 4Da are attached to the distal end 4G2a of the lower link 4G2. The lower rolling element 4 </ b> D provided therethrough moves toward the rear standing wall 22 b of the lower rail groove 22. As a result, as shown in FIG. 23, the switching mechanism 4E of each switching unit 422 releases the contact state of the upper contact body 4A with respect to the opening-side standing wall 21a of the upper rail groove 21 and moves the upper rolling element. 4C is brought into contact with the opening-side standing wall 21a of the upper rail groove 21, and the lower-side rolling element 4D is released by releasing the contact state of the lower-side contact body 4B with the rear-side standing wall 22b of the lower rail groove 22 Is allowed to move in contact with the rear standing wall 22b of the lower rail groove 22. Thereby, the top plate 5 can be slid with respect to the base 2 together with the movable support 4. In the present embodiment, the auxiliary rolling element 4H that can be brought into contact with the bottom wall 21c of the upper rail groove 21 is provided in the main body portion 4211 of the slide device 42 (see FIGS. 18 and 23).

  In this embodiment, since the rolling elements 4C and 4D are relatively moved with respect to the contact bodies 4A and 4B in accordance with the above operation, the switching mechanism 4E is changed from the movement restricted state to the movement permitted state. In the case of switching, the relative angle of the movable support 4 with respect to the base 2 is displaced, and an angle posture in which the anti-base 2 side of the movable support 4 jumps up (see FIGS. 22 and 23). In accordance with such an angle change of the movable support 4 with respect to the base 2, the top plate 5 connected to the movable support 4 by the hinge mechanism H and having the other end supported by the leg 6 is shown in FIG. As shown in FIGS. 21 and 22, it rotates about the hinge axis H <b> 1 and rotates in a direction that rises with respect to the movable support 4. Thus, since the relative angle of the top plate with respect to the movable support 4 is set to be changeable, when the slide device 42 is switched from the movement restricted state to the movement permitted state by the switching mechanism 4E, the movable support is supported with respect to the base 2. Only the operation force that changes the angle of the body 4 is required, and the operation force that is much lighter than the aspect that requires the operation force to integrally and simultaneously jump (change the angle) the top plate together with the support relative to the base. The switching operation can be performed with. Further, when the switching mechanism 4E is switched from the movement restricted state to the movement permitted state, the priority support closest to the hinge axis H1 among the plurality of priority support portions 412 is obtained along with the relative angle change between the movable support 4 and the top plate 5. Only a part of the portion 412 hits the lower surface of the movable top plate body 511, and the contact state between the other priority support portions 412 and the top plate 5 is released.

  On the other hand, the operation of switching the switching mechanism 4E of each switching unit 422 from the movement-permitted state to the movement-restricted state grips the knob 4241a of the slide operation lever 4241 exposed from the reinforcing body 4212 and moves the slide operation lever shaft 4242. The operation is performed by rotating the slide operation lever 4241 in the center in the direction of arrow B in FIGS. As the slide operation lever 4241 rotates, the link interlocking body 4231 moves toward the reinforcing body 4212, and the links 4G1 and 4G2 of the switching units 422 are interlocked to rotate around the link shaft 4232, respectively. To do. The upper side link 4G1 and the lower side link 4G2 rotate around the common link shaft 4232 in the opposite direction to the case where the switching mechanism 4E is switched from the movement restricted state to the movement permitted state. The upper rolling element 4C provided at the distal end 4G1a moves in a direction away from the opening side standing wall 21a of the upper rail groove 21, and the lower rolling element 4D provided at the distal end 4G2a of the lower link 4G2. Moves in a direction away from the rear side standing wall 22b of the lower rail groove 22. As a result, the movable support 4 moves in the direction in which it sinks due to the weight of the movable support 4 itself and the weight of the top plate 5, and the switching mechanism 4E of each switching unit 422 moves the upper rail as shown in FIG. The contact state of the upper rolling element 4C with respect to the opening side standing wall 21a of the groove 21 is released, and the upper side contact body 4A is brought into contact with or pressed against the opening side standing wall 21a of the upper rail groove 21, and the lower side The movement restriction in which the contact state of the lower rolling element 4D with respect to the rear standing wall 22b of the rail groove 22 is released and the lower contact body 4B is brought into contact with or pressed against the rear standing wall 22b of the lower rail groove 22 It becomes a state. The auxiliary rolling element 4H is also lifted from the bottom wall 21c of the upper rail groove 21. As a result, the sliding movement of the movable support 4 and, consequently, the top plate 5 relative to the base 2 is restricted.

  In the present embodiment, when the switching mechanism 4E is switched from the movement-permitted state to the movement-restricted state, the top plate 5 rotates around the hinge axis H1 of the hinge mechanism H according to the relative angle change of the movable support 4 with respect to the base 2. And turn toward the movable support 4 to be supported by the priority support portions 412.

  In the present embodiment, the side lock lever 4I is provided in the slide device 42 in order to complement the slide movement / regulation function of the switching mechanism 4E. The side lock lever 4I is rotatable about the side lock lever shaft 4Ia, and a state in which the pressing surface 4Ib provided at the base end is pressed against or abutted against the rising surface 2A of the base 2, and It can be switched between the pressure contact state or the state in which the contact state is released. In addition, the rotation of the slide operation lever 4241 at the time of the switching operation is restricted by a part of the slide operation lever 4241 coming into contact with the contact portion 4243a of the slide operation lever abutting plate 4243.

  In addition, the desk 1 according to the present embodiment is such that the top plate 5 can be swiveled horizontally with respect to the movable support body 4 by the action of the turning mechanism 52 as described above. By turning in the turning stopper rail 5122 which is an “intrusion target portion” integrally provided on the lower surface side of 511, the turning restriction state for restricting horizontal turning of the top plate 5 and the releasing state are released. A pinching mechanism 4J is provided that can be switched between a swing-permitted state that allows the top plate 5 to turn horizontally (see FIGS. 17 and 21).

  Here, the turning stopper rail 5122 that plays a role as the “pinch target portion” will be described in detail.

The width dimension of the operation part 4J2 is set smaller than the separation dimension between the outward faces of the hanging pieces 4J12 of the retractable body 4J1.

  In the present embodiment, the pinching mechanism 4J is provided in association with the reinforcing frame 411d of the frame body 411 of the support body 4.

  The operation unit support 4J3 includes a pair of upright pieces 4J31 whose distal ends are fixed to the reinforcing frame 411d by welding or the like, and connection pieces 4J32 that connect the upper ends of the base end portions of the upright pieces 4J31. . In the present embodiment, the upright pieces 4J31 and the connecting pieces 4J32 are formed by bending a single steel plate. A retractable body rotating shaft second insertion hole 4J31a that communicates with a retractable body rotating shaft first insertion hole 4J12a formed in the hanging piece 4J12 of the retractable body 4J1 is formed on the distal end side of each standing piece 4J31. A second guide hole 4J31b that defines a movement trajectory of the operation portion 4J2 when an operation force is applied to the operation portion 4J2 is formed at a substantially central portion in the longitudinal direction of each standing piece 4J31. In the present embodiment, a long hole extending along the longitudinal direction of each upright piece 4J31 is applied as the second guide hole 4J31b. In addition, the separation dimension between the inward surfaces of the upright pieces 4J31 is set larger than the separation dimension between the outward surfaces of the hanging pieces 4J12 of the retractable body 4J1.

  The operation portion abutting plate 4J4 has a substantially U-shape in cross-section, including an upright piece 4J41, and an upper piece 4J42 and a lower piece 4J43 extending forward from the upper and lower edges of the upright piece 4J41. In the present embodiment, the upright pieces 4J41, the upper pieces 4J42, and the lower pieces 4J43 are formed by bending a single steel plate. Then, the upper piece 4J42 protruding forward from the lower piece 4J43 is fixed to the upper surface portion of the auxiliary frame 411d by welding or the like, and the front end portion of the lower piece 4J43 is fixed to the rear surface portion of the auxiliary frame 411d by welding or the like. ing. The standing piece 4J41 is formed with a pair of rotation stopper pin insertion holes 4J41a into which a pair of rotation stopper pins 4JP can be inserted. The reinforcing frame 411d is formed with a rotation stopper pin hole 411da capable of accommodating the rotation stopper pin 4JP, and a rotation stopper pin accommodation space 4J2s capable of accommodating the rotation stopper pin 4JP is formed at the base end of the operation portion 4J2. (See FIG. 14).

  Then, the rotation stopper pin 4JP is continuously inserted into the rotation stopper receiving hole 411da of the reinforcing frame 411d and the rotation stopper pin insertion hole 4J41a of the operation portion abutting plate 4J4, and the tip portion of each rotation stopper pin 4JP is inserted into the operation portion. It is positioned in the 4J2 rotation stopper pin accommodating space 4J2s. In this state, the second guide hole 4J31b of the operation portion support 4J3, the first guide hole 4J12b of the retractable body 4J1, the first insertion hole 4J23 for the operation portion rotation shaft of the operation portion 4J2, and the distal end portion of the rotation stopper pin 4JP. The formed second insertion hole 4JPa for operation unit rotation shaft is communicated with each other, and the rotation shaft 4JY of the operation unit 4J2 is continuously inserted into each of the holes 4J31a, 4J12b, 4J23, 4JPa. On the other hand, the second insertion hole 4J31a for the retractable body rotating shaft of the operating portion support body 4J3 and the first insertion hole 4J12a for the retractable body rotating shaft of the retractable body 4J1 are connected to each other, and the retractable body 4J1 is inserted into each of the holes 4J31a, 4J12a. The rotation shaft 4JX is continuously inserted. As described above, the squeezing mechanism 4J formed by associating the reinforcing frame 411d, the retractable body 4J1, the operation portion 4J2, the operation portion support body 4J3, and the operation portion abutment plate 4J4 is integrally assembled to the support body 4. The reinforcement frame 411d is set at an attachment position so as to substantially coincide with a virtual straight line connecting the pair of priority support portions 412 provided on the base 2 side among the plurality of priority support portions 412 provided on the support body 4. The swaging mechanism 4J provided in the reinforcing frame 411d is positioned in the support area of the priority support portion 412 or in the vicinity of the support area (see FIGS. 17 and 18 described later). The rotary shafts 4JX and 4JY are prevented from coming off by large-diameter heads, fasteners such as E-rings, or caulking.

  Next, an operation method and operation of the scavenging mechanism 4J will be described.

  When the retractable body 4J1 is positioned at the retractable position (A), the horizontal rotation of the top plate 5 is regulated by gripping the horizontal portion 5122b of the swing stopper rail 5122 by the gripping claws 4J11a of the retractable body 4J1. (See FIG. 8). In this case, the operation portion 4J2 makes the linear portion of the cam surface 4J22 contact or pressure contact with the operation portion abutment plate 4J4, and has a substantially horizontal posture as a whole, and its maximum height dimension is the maximum height dimension of the frame body 411. Smaller. Further, the rotation shaft 4JY of the operation portion 4J2 is positioned at the lower edge of the first guide hole 4J12b formed in the retractable body 4J1, and the rear edge of the second guide hole 4J31b formed in the operation portion support body 4J3 (anti-base 2). Position). When the rotation shaft 4JY of the operation portion 4J2 is locked in a state where it is positioned at the lower edge of the first guide hole 4J12b, the rotation of the retractable body 4J1 around the rotational shaft 4JX is restricted, and the retractable body 4J1 is It is locked at the retractable position (A). Further, when the swaging mechanism 4J is in the turning restricted state, the lower surface of the movable top plate main body 511 is supported at a plurality of points by the respective priority support portions 412.

  On the other hand, the swaging mechanism 4J is switched from the turning restricted state to the turning allowed state by gripping the knob 4J21 of the operation unit 4J2 and applying an operation force that rotates the operation unit 4J2 downward. Based on this operation force, the operation unit 4J2 rotates downward about the rotation shaft 4JY. Then, the object that abuts or presses against the operation unit abutment plate 4J4 at the next point after the operation unit 4J2 is rotated by a predetermined angle is switched from the straight part of the cam surface 4J22 of the operation unit 4J2 to the curved part, and the rotation shaft 4JY of the operation unit 4J2 is changed. It moves forward (base 2 side) along the second guide hole 4J31b. Along with the movement of the rotating shaft 4JY, the retractable body 4J1 rotates rearward (on the side opposite to the base 2) around the rotating shaft 4JX, and the nail claw 4J11a is separated from the horizontal portion 5122b of the turning stopper rail 5122. It moves to the nudge release position (B) that has been made (see FIG. 15). The rotation trajectory between the retractable position (A) and the retracting position (B) of the retractable body 4J1 is defined by the first guide hole 4J12b. That is, when the retractable body 4J1 moves between the retractable position (A) and the retractable release position (B), the height position of the rotary shaft 4JY of the operation unit 4J2 is unchanged, and the retractable body 4J1 When positioned at the retractable position (A), the rotation shaft 4JY of the operation portion 4J2 is positioned at the lower edge of the first guide hole 4J12b, and the retractable body 4J1 is positioned at the retracting position (B). The rotation shaft 4JY of the operation unit 4J2 is positioned at the upper edge of the first guide hole 4J12b. Further, when the retractable body 4J1 is moved from the retractable position (A) to the retractable position (B), a part of the hanging piece 4J12 of the retractable body 4J1 comes into contact with the reinforcing frame 411d so that the retractable body 4J1. Is further restricted in the same direction. Since the rotary shaft 4JX is provided at a position displaced from the center of gravity of the retractable body 4J1, the movement of the retractable body 4J1 from the retractable position (A) to the retracting position (B) is caused by the weight of the retractable body 4J1. Can be used. By moving the retractable body 4J1 from the retractable position (A) to the retracting position (B) in this way, the retracting mechanism 4J causes the retraction of the turning stopper rail 5122 by the retractable body 4J1 and the reinforcing frame 411d. Is in a turning-permitted state where the top plate 5 is allowed to turn horizontally, and as shown in FIGS. 17 and 18, a posture in which the longitudinal direction of the top plate 5 is substantially orthogonal to the longitudinal direction of the base 2, Alternatively, the turning angle posture of the top plate 5 with respect to the base 2 such as a posture in which the longitudinal direction of the top plate 5 is substantially parallel to the longitudinal direction of the base 2 can be appropriately selected. In FIGS. 17 and 18, the retracting mechanism 4J in which the retractable body 4J1 is in the retractable position (A) is shown, and a part of the retracting mechanism 4J is omitted.

  Then, when the swaging mechanism 4J is in a turning-permitted state, the top plate 5 is in a state of being able to rotate in the direction of lifting with respect to the support body 4 around the hinge axis H1 of the hinge mechanism H as shown in FIG. .

  Thus, by moving the retractable body 4J1 from the retractable position (A) to the retracting position (B), the retracting mechanism 4J releases the swung stopper rail 5122 from the retracted state by the retractable body 4J1. , A turning permission state in which the top plate 5 is allowed to turn horizontally, as shown in FIGS. 17 and 18, a posture in which the longitudinal direction of the top plate 5 is substantially orthogonal to the longitudinal direction of the base 2, or the top plate 5 A turning angle posture of the top plate 5 with respect to the base 2 such as a posture in which the longitudinal direction is substantially parallel to the longitudinal direction of the base 2 can be appropriately selected. In FIGS. 17 and 18, the retracting mechanism 4J in which the retractable body 4J1 is in the retractable position (A) is shown, and a part of the retracting mechanism 4J is omitted.

  On the other hand, the operation of switching the swaging mechanism 4J from the turning permission state to the turning restriction state is performed by applying an operation force that returns the operation unit 4J2 to the original position. In addition, before performing the operation which switches the swaging mechanism 4J from a turning permission state to a turning control state, it is necessary to return the top plate 5 to the normal use position shown in FIG. Then, when the knob 4J21 of the operation unit 4J2 is gripped and an operation force for rotating the operation unit 4J2 upward is applied, the operation unit 4J2 rotates upward about the rotation shaft 4JY. Then, when the operation unit 4J2 is rotated by a predetermined angle, the object to be in contact with or pressed against the operation unit abutment plate 4J4 is switched from the curved portion of the cam surface 4J22 of the operation unit 4J2 to the linear portion, and the rotation shaft 4JY of the operation unit 4J2 is changed to the first. 2 Moves backward (on the side opposite to the base 2) along the guide hole 4J31b. As the rotary shaft 4JY moves, the retractable body 4J1 rotates toward the front (base 2 side) around the rotary shaft 4JX and grips the horizontal portion 5122b of the turning stopper rail 5122. Positioned at (A). In this way, by moving the retractable body 4J1 from the retracting position (B) to the retractable position (A), the horizontal portion 5122b of the turning stopper rail 5122 is pulled downward (reinforcing frame 411d side), and the top plate 5 horizontal turning is restricted. In this way, the retracting body 4J1 of the switching mechanism 4J pushes the horizontal portion 5122b of the turning stopper rail 5122 downward along with the operation of switching the swaging mechanism 4J from the turning permission state to the turning restriction state, thereby turning the turning stopper rail 5122. At the same time, the movable top plate main body 511 is drawn downward, and the lower surface of the movable top plate main body 511 is in pressure contact with the priority support portion 412, and a good support state of the top plate 5 is ensured. In addition, the rotation locus between the retractable position (A) and the retracting position (B) of the retractable body 4J1 is defined by the first guide hole 4J12b as described above. Further, when the operation of moving the retractable body 4J1 from the insertion release position (B) to the insertion-possible position (A) is performed, a part of the operation unit 4J2 comes into contact with the connection piece 4J32 of the operation unit support 4J3. This restricts further rotation of the operation portion 4J2 in the same direction.

  By switching the swaging mechanism 4J between the swiveling restricted state and the swiveling permitted state by the operation as described above, it is possible to control the permission / restriction of the turning motion of the top plate 5, and this swaging mechanism 4J Further, it is possible to control the allowance / restriction of the rotation of the top plate 5 in the flying direction using the hinge mechanism H.

  That is, when the swaging mechanism 4J is in the turning restricted state, as shown in FIG. 8, the turning mechanism 5 is restricted from turning in the flying direction of the top plate 5 using the hinge mechanism H. As shown in FIG. 16, the insertion mechanism 4 </ b> J is in a rotation-permitted state in which the top plate 5 using the hinge mechanism H is allowed to rotate in the flying direction. That is, the scooping mechanism also functions as a top plate lift regulation mechanism that regulates the lifting operation of the top plate.

  Further, as shown in FIGS. 17 and 18, the hinge mechanism H according to the present embodiment has a posture in which the longitudinal direction of the top plate 5 is substantially orthogonal to the longitudinal direction of the base 2 or the longitudinal direction of the top plate 5. Non-direction that allows the top plate 5 to rotate in the flying direction regardless of the turning angle posture of the top plate 5 with respect to the support 4 and the base 2, such as a posture substantially parallel to the longitudinal direction of the base 2. Sexual rotation permission means. In this embodiment, the rotation permitting means is realized by making the hinge shaft second insertion hole 4111d formed in the hinge bearing body 4111 into a long hole.

  That is, as shown in FIG. 17, when the top plate 5 is set to a turning angle whose longitudinal direction is substantially orthogonal to the longitudinal direction of the base 2, the longitudinal direction of the top plate 5 and the hinge shaft H1 As shown in FIG. 19, the hinge shaft H1 rotates in the hinge shaft second insertion hole 4111d without substantially changing its height position, and moves in the direction in which the top plate 5 floats. Is allowed to rotate.

  On the other hand, as shown in FIG. 18, when the top plate 5 has a longitudinal direction set at a turning angle substantially parallel to the longitudinal direction of the base 2, the longitudinal direction of the top plate 5 and the axis of the hinge shaft H1. As shown in FIG. 20, the hinge shaft H1 is lifted up in the second insertion hole 4111d for the hinge shaft as the top plate 5 rotates in the floating direction. Tilt (fly) according to the angle (rotation angle). Thereby, the smooth rotation to the floating direction of the top plate 5 is ensured. In FIG. 19 and FIG. 20, the pinching mechanism 4J and the turning stopper mechanism 4K are omitted. Further, in FIG. 18, the swivel mechanism 4J is in the turning restricted state (turning restricted state), and thus the rotation of the top plate 5 in the flying direction is restricted. In FIG. 20 that is partially omitted, for convenience of explanation, a state in which the top 5 is rotated in the flying direction is shown.

  In addition, the desk 1 according to the present embodiment includes a fixed top 5 </ b> X whose relative position cannot be changed with respect to the base 2.

  The fixed top plate 5X has, for example, a longitudinal dimension that is substantially the same as or slightly smaller than the longitudinal dimension of the base 2. In the present embodiment, a substantially rectangular shape in plan view is applied as the fixed top plate 5X. This fixed top plate 5X is supported by a fixed support 4X.

  As shown in FIG. 35, the fixed support 4X includes a mounting portion 4X1 that can be mounted in the rail grooves 21 and 22 of the base 2, and an arm portion 4X2 that extends from the mounting portion 4X1 toward the lower surface of the fixed top plate 5X. It is provided.

  The present invention is not limited to the embodiment described in detail above.

  For example, a top plate that is supported by simply placing it on the movable support may be applied, or a top plate that is supported by the movable support so as not to be horizontally pivotable may be applied.

  In the above embodiment, the base has been illustrated as a base that extends linearly. However, the present invention is not limited thereto, and the base extends in a curved shape (circular curved shape, elliptical curved shape), or extends while meandering. May be.

  In addition, a mode in which a plurality of (for example, two ends) of the top plate are respectively supported by a plurality of (for example, two) movable supports supported by the same base, or a part of the top plate (for example, one end) is supported. A mode in which a movable support supported by one base is supported and another part (for example, the other end) of the top plate is supported by a movable support supported by another base may be adopted. .

  Similarly, a part (for example, one end) of the fixed top plate is supported by a fixed support supported by one base, and another part (for example, the other end) of the fixed top plate is supported by another base. Alternatively, a mode in which the fixed support is supported may be employed.

  On the other hand, in the case where a part of the top plate is supported by the legs, a leg that is not provided with a moving body at the lower end may be applied. In this case, in order to move the top plate, the top plate may be moved up to a position where the lower end of the leg floats from the floor surface. Furthermore, the leg may be provided with an adjuster for correcting the unevenness of the leg or the inclination of the top plate.
