Description

Furniture

Technical Field

The invention relates to furniture with optional parts.

Background

Conventionally, in furniture with a top plate such as an office table or a desk, for example, it is conceivable that a plurality of fitting holes capable of fitting an optional component support member for supporting an optional component such as a task lamp are formed at a predetermined pitch on the opposite side of the use side, and an insertion portion provided in the optional component support member is inserted into a fitting hole selected from the plurality of fitting holes, whereby the mounting position of the optional component can be changed (for example, see patent document 1).

Patent document 1: japanese patent laid-open No. 2001-169834.

However, in the conventional furniture, since the mounting position of the optional component to be selected is determined by the formation position of the fitting hole, there is a problem that the mounting position of the optional component cannot be finely adjusted, and in addition, when the mounting position of the optional component is changed, it is necessary to once release the fitting state of the insertion portion and the fitting hole and then insert the insertion portion again into a different fitting hole, which is very troublesome, and there is a problem that the mounting position of the optional component cannot be easily and reliably changed in accordance with the arrangement posture of the top plate. In particular, in the case of an office table in which the top plate is changeable in posture with respect to the base and is also capable of coping with changes in layout, there are many opportunities to change the mounting position of the optional components in accordance with changes in posture of the top plate.

Disclosure of Invention

The present invention has been made in view of the above problems, and a main object of the present invention is to provide a piece of furniture in which the degree of freedom of changing the position of an optional member with respect to a base can be increased, and the position of the optional member with respect to the base can be changed easily and reliably in accordance with the arrangement posture of a top plate with respect to the base.

Specifically, the furniture according to the present invention includes: a base extending along a predetermined direction; a top plate capable of selecting a plurality of arrangement postures with respect to the base; an optional component support supported movably along the base according to the arrangement posture of the top plate; and an optional component supported on the optional component support.

According to this configuration, since the optional component support is movable relative to the base, not only is the degree of freedom in changing the position of the optional component relative to the base increased, but also the operation of temporarily releasing the fitting state between the insertion portion and the fitting hole and fitting the insertion portion into a different fitting hole is not required every time the mounting position of the optional component is changed as in the conventional art, and the position of the optional component relative to the base can be changed easily and reliably by the worker himself/herself according to the posture of the top plate relative to the base, and the working environment of the worker can be satisfied. Further, since the range of movement of the optional component support is restricted by the base, the entire work space and office can be prevented from becoming irregularly disordered as the position of the optional component is changed, and the present invention is excellent in suitability as furniture constituting the work space and office in which layout change is frequently performed.

Here, the "top plate capable of selecting a plurality of arrangement postures with respect to the base" is a concept including any one of a top plate supported on the base, and a top plate supported on legs or the like without being supported on the base and independent from the base.

Another piece of furniture according to the present invention includes: a base extending along a predetermined direction, a top plate capable of selecting a plurality of arrangement postures relative to the base, and an optional component support supported movably along the base according to the arrangement postures of the top plate; and an optional component supported on the optional component support; the optional component support is movable together with the optional component relative to the base in a state of supporting the optional component.

Such furniture can also achieve substantially the same effects as those of the above-described furniture, and in addition, when the relative arrangement position of the optional member with respect to the base is changed, the operation of removing the optional member from the optional member support or re-attaching the optional member again is not required, and the operability is excellent. The "top plate capable of selecting a plurality of arrangement postures with respect to the base" is a concept including any of a top plate supported by the base, and a top plate supported by legs or the like without being supported by the base and independent from the base, as described above.

In particular, if the optional component support is a component that supports one or more optional components selected from among a plurality of types of optional components different from each other, it is possible to achieve a general use of parts and a reduction in the number of parts, as compared with a case where a dedicated optional component support is prepared for each type of optional component different from each other.

Further, if the optional component support is a component that detachably supports the optional component, the optional component supported by the optional component support can be appropriately selected according to the use of the desk, and the utility is very excellent.

Further, if the optional member support is a member that supports the optional member so as to be horizontally rotatable, the relative angle of the optional member with respect to the base can be adjusted in accordance with the relative angle of the top plate with respect to the base, and wide versatility can be provided.

In order to smoothly and reliably move the optional component support with respect to the base, the base may be provided with a guide portion for guiding the movement of the optional component support, and the optional component support may be provided with a guided portion guided by the guide portion. In this case, as a preferred embodiment, the guide portion is a guide rail formed along the extending direction of the base, and the guided portion is an insertion portion movable along the guide rail in a state of being inserted into the guide rail.

In addition, as a specific form of the plurality of different optional components, there is exemplified a storage tool including: the storage device comprises a storage device body having a storage space therein, and a leg support for holding the storage device body at a certain height position. In this case, since the storage device body can be held at a constant height position by the leg stay, a constant space is formed below the storage device body, and different optional components can be further arranged by using the space, and it is possible to cope with various operation modes using various optional components. In addition, depending on the setting of the height position of the container body, the container body can also function as a screen.

The base has a plurality of guide portions which are continuously provided along the extending direction and guide the movement of the optional component support, and a plurality of kinds of optional components with different kinds can be mounted by the optional component support which is respectively supported on the guide portions; the height dimension of the leg stay of the storage tool supported by the option component support guided by one guide portion is set to a dimension that can avoid interference between the storage tool body and another option component when the leg stay is crossed with another option component supported by the option component support guided by another guide portion. In this way, when the relative arrangement position between the storage tool and the other optional components is changed according to the arrangement position of the top plate or the use state of the user, the storage tool and the other optional components can be moved along the guide portion in a state of being supported on the optional component support, and the operation of changing the relative position between the optional components can be performed relatively easily.

Further, if the leg stays support a portion of the container body which becomes the center of gravity of the container body, the container body can be supported in a stable state by the leg stays, and the operation of moving the container along the base via the optional member support can be performed in a smooth and stable state.

As another embodiment of the storage tool, the storage space of the storage tool body is open at least at the user side, and the leg stay supports a portion of the storage tool body that is offset to the side opposite to the open side. In this case, when the base includes a plurality of guide portions that are provided continuously along the extending direction and guide the movement of the option member supporter, the storage device bodies can be arranged on the guide portions via the option member supporter in a back-to-back posture, and when the storage device bodies are staggered with each other, the interference between the storage device bodies can be avoided.

As described above, according to the present invention, the degree of freedom in changing the position of the optional member with respect to the base can be increased, the position of the optional member with respect to the base can be easily and reliably changed in accordance with the arrangement posture of the top plate with respect to the base, and the work environment of the worker can be satisfied.

Detailed Description

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

As shown in fig. 1, the present embodiment employs a desk 1 as furniture, which includes: a base 2 disposed on the floor and extending in a predetermined direction; a base support 3 for supporting the base 2; a top plate support 4 supported to be slidable along the base 2; a top plate 5a (or 5b) having one end supported by the top plate support 4; a leg 6 for supporting the other end of the top plate 5a (or 5b) to contact the ground. Fig. 1 is a diagram showing an office configuration system in which 2 office desks 1 are connected, and the office components have substantially the same shape and configuration except for the top plates 5a and 5b, and corresponding members are given the same reference numerals in the drawing.

The base 2 is, for example, a substantially rectangular column-shaped member extending substantially linearly. A pair of standing surface portions 21 facing each other in the longitudinal direction in the base 2 are provided with a top plate guide portion 2A for guiding the movement of the top plate support 4. The top guide 2A is configured by a guide rail 2A formed along the longitudinal direction of the base 2. In the present embodiment, the ceiling guide portion 2A is formed by a pair of recessed guide rails 2A extending in parallel with each other at a predetermined pitch in the height direction on each standing surface portion 21 and recessed from the other portions. Further, an optional component guide portion 2B (corresponding to a "guide portion" in the present invention) is provided on the upper surface portion 22 of the base 2. The optional component guide portion 2B is configured by a guide rail 2B formed along the longitudinal direction of the base 2. In the present embodiment, the optional component guide portion 2B is configured by a groove-like guide rail 2B recessed from the other portions in the upper surface portion 22. The guide portions 2A and 2B are formed from one end of the base 2 to the other end thereof. End caps 2C are detachably attached to both end portions of the base 2.

The base support 3 is a member that supports both ends of the base 2. In the office building system of the present embodiment in which the base supports 3 are, for example, square columns having a depth dimension substantially equal to the short-direction dimension of the base 2 and a plurality of desks 1 are connected so that the bases 2 are continuous in the longitudinal direction, the auxiliary base supports 3a are integrally assembled by an appropriate means at least on the base supports 3 located at both ends as viewed from the entire office building system among the plurality of base supports 3, thereby achieving excellent self-standing and stability of the entire office building system.

As shown in fig. 1, the top support 4 is a member including a top plate receiving portion 31 for supporting the top plate 5a (or 5b) and a guided portion 42 guided by the top plate guide portion 2A.

The top plates 5a and 5b are plate-like members each having a substantially gourd-like shape in plan view (an elliptical shape with a center portion thereof being recessed) or a substantially rectangular shape in plan view, and have a maximum longitudinal dimension substantially equal to or smaller than a longitudinal dimension of the base 2. One end portions of the top plates 5a and 5b are supported by the top plate support 4 so as to be horizontally rotatable. As a specific form of rotatably supporting the top plates 5a and 5b on the top plate support 4, for example, a simple single-shaft structure using a single shaft is exemplified. In the present embodiment, the lower surfaces of the top plates 5a and 5b are set to be slightly above the upper surface portion 22 of the base 2, so that the top plates 5a and 5b do not interfere with the base 2 when the top plates 5a and 5b are horizontally rotated. Further, although the top plates 5a and 5B are partially overlapped with the upper surface 22 of the base 2 at a predetermined distance in the height direction, the top plates 5a and 5B are partially not overlapped with the guide portion 2B for the optional member formed on the upper surface 22 of the base 2, and interference between the part of the optional member guided by the guide portion 2B for the optional member and the parts of the top plates 5a and 5B is avoided.

The leg 6 is a member including a leg body 61 for directly supporting the other end portions of the top plates 5a and 5b, and casters 62 provided at the lower end portion of the leg body 61.

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 in the longitudinal direction of the base 2, and can appropriately select the rotational angle postures of the top plates 5a and 5b with respect to the base 2, that is, postures in which the longitudinal directions of the top plates 5a and 5b are substantially parallel to the longitudinal direction of the base 2, postures in which the longitudinal directions of the top plates 5a and 5b are substantially perpendicular to the longitudinal direction of the base 2, and the like.

In the office configuration system of the present embodiment in which 2 office tables 1 are connected as described above, as shown in fig. 1 and 2(a), the top plate 5a or 5b is set in a posture in which the longitudinal direction thereof is substantially perpendicular to the longitudinal direction of the base 2, respectively, and the top plates 5a and 5b are positioned on the side of the base 2 away from the other base 2 (the side opposite to the connecting end), so that it is possible to set a first layout in which the workers using the top plates 5a and 5b face back to back, thereby forming a work space and an office in which the workers can perform tasks in a concentrated manner. In fig. 2, the base 2 is indicated by a hatching pattern. Further, as shown in fig. 2b, by setting the top boards 5a and 5b in postures in which the longitudinal directions thereof are substantially perpendicular to the longitudinal direction of the base 2, respectively, and positioning the top boards 5a and 5b on the side (connecting end side) of the base 2 connected to the other base 2, a second layout can be set in which workers using the top boards 5a and 5b can face each other, the second layout forming a work space and an office layout in which workers can perform tasks while communicating information with each other. Further, as shown in fig. 2(c), by setting the top boards 5a and 5b in postures in which the longitudinal directions thereof are substantially parallel to the longitudinal direction of the base 2, and arranging the top boards 5a and 5b in parallel along the longitudinal direction, it is possible to set a third layout in which the workers using the top boards 5a and 5b are arranged in the lateral direction. The third layout is a layout in which a workspace and an office are formed so that each worker can communicate with each other while performing tasks in a concentrated manner. Further, by moving the optional components along the base 2 by the optional component guide portion 2B in accordance with the layout, a work space and an office excellent in workability can be formed. This makes it possible to set a layout appropriately selected from among layouts of at least 3 patterns. In fig. 1 and 2, partition walls P are disposed to partition the working spaces of the workers. In the present embodiment, a mounting member Pa (see fig. 1) for mounting the partition wall P to the base 2 is provided at a part of the partition wall P. A layout without the partition wall P may be adopted according to the selection of the worker. When the desks 2 are integrally connected to each other, a not-shown connecting device for integrally connecting the one base 2 and the other base 2 may be used. Examples of the connecting means include: a connecting device using an engaging portion provided on each end cap and engageable with (concavo-convex engaged or hooked to) an adjacent end cap, a connecting device using an engaging portion provided on an end portion of a base and engageable with (concavo-convex engaged or hooked to) an end portion of an adjacent base, or a connecting device using a fastening member such as a screw for fastening and connecting the bases 2 to each other.

The desk 1 of the present embodiment further includes an optional member whose position can be changed with respect to the base 2. In the present embodiment, a panel system PS in which a desk top panel DTP and a tidying rack ST are integrally provided, and a work light TL are used as optional components.

The panel system PS is provided with guided portions PSx guided by the optional component guide portions 2B in pairs, integrally or integrally at a lower end portion (in the illustrated example, a lower end portion of the table top panel DTP). In the present embodiment, as the guided portion PSx, an insertion portion that can move along the guide rail 2b in a state of being inserted into the guide rail 2b is used. In the panel system PS, the guided portion PSx also functions as an "optional component support" of the present invention that is supported movably with respect to the base 2.

On the other hand, the operating lamp TL is supported by an optional component support 7 that is separate from the operating lamp TL. The optional member support 7 is a member supported movably with respect to the base 2, and includes a guided portion 7a guided by the guide portion 2B for an optional member. In the present embodiment, as the guided portion 7a, an insertion portion that can move along the guide rail 2b in a state of being inserted into the guide rail 2b is used. The optional component holder 7 is provided with a fitting portion 7b into which an insertion portion (not shown) provided at a lower end portion of the operating lamp TL can be fitted, and the operating lamp TL is set to be horizontally rotatable about a fitting portion between the insertion portion and the fitting portion 7b in a state where the operating lamp TL is supported by the optional component holder 7 by fitting the insertion portion of the operating lamp TL into the fitting portion 7 b.

By sliding the panel system PS and the operating lamp TL along the base 2, the relative positions of the panel system PS and the operating lamp TL with respect to the base 2 can be changed.

Therefore, the panel system PS and the work lamp TL for improving the workability of the worker using the top boards 5a and 5b can be moved to the optimum positions along the base 2 in accordance with the arrangement postures of the top boards 5a and 5b with respect to the base 2.

In the present embodiment, the operation lamp TL is detachably supported by the optional component support 7, and another type of optional component, for example, a screen panel EP shown in fig. 3 and 4(a) (fig. 4(a) is a view schematically showing a plan view of fig. 3) may be supported by the optional component support 7 instead of the operation lamp TL. Specifically, an insertion portion (not shown) that can be inserted into the fitting portion 7b of the optional component support 7 is provided on the lower end portion of the screen panel EP. In a state where the insertion portion is fitted into the fitting portion 7b, as shown in fig. 4(a), the screen panel EP is supported on the optional component support 7 so as to be horizontally rotatable about the fitting portion. Thus, as shown in fig. 4(b), even when a layout is adopted in which the longitudinal direction of the top plate 5b is set to, for example, about 45 degrees with respect to the longitudinal direction of the base 2, the relative angle of the screen panel EP with respect to the base 2 can be made to correspond to the relative angle of the top plate 5b and the base 2 by rotating the screen panel EP by a predetermined angle.

As described above, the desk 1 of the present embodiment includes: a base 2 extending along a predetermined direction, top plates 5a, 5b capable of selecting a plurality of arrangement postures with respect to the base 2, an optional component support 7 (and a guided portion PSx functioning as an optional component support) movably supported along the base 2 in accordance with the arrangement posture of the top plates 5a and 5b, and optional components (working lamp TL, screen panel EP, panel system PS) supported on the optional component support 7, guided portion PSx, therefore, the work of temporarily releasing the fitting state of the insertion portion and the fitting hole and fitting the insertion portion into a different fitting hole every time the relative position of the optional component with respect to the base is changed as in the conventional art is not required, and the relative positions of the worklight TL, the screen panel EP, and the panel system PS with respect to the base 2 can be easily and reliably changed by the worker himself. Further, since the optional component support 7 and the guided portion PSx can be moved to slide along the base 2 steplessly, the positions of the work lamp TL, the screen panel EP, and the panel system PS can be finely adjusted. Further, since the movable range of the optional component support 7 and the guided portion PSx is limited by the base 2, the working space and the entire office can be prevented from becoming disordered due to the positional change of the work lamp TL, the screen panel EP, and the panel system PS, and the present invention is suitable for office furniture constituting a working space and an office in which layout change is frequently performed, and can make the working environment of the worker more sufficient.

In particular, since the optional component support 7 is a member that supports an optional component appropriately selected from a plurality of kinds of optional components (in the embodiment, the task lamp TL and the screen panel EP) different in kind, it is possible to make the parts common and reduce the number of parts compared to a configuration in which a dedicated optional component support is prepared for each kind of optional component different in kind.

In addition, since the optional component support 7 is a member for detachably supporting the optional component (in the embodiment, the work lamp TL and the screen panel EP), the optional component supported by the optional component support 7 can be appropriately selected and mounted according to the work environment, which is an excellent practical solution.

Further, since the optional component support 7 is a member for supporting the optional component (the task lamp TL and the screen panel EP in the embodiment) so as to be horizontally rotatable, the relative angle of the optional component with respect to the base 1 can be adjusted in accordance with the relative angle of the top plates 5a and 5b with respect to the base 2, and a wide versatility can be provided.

Further, since the base 2 is provided with the optional component guide portion 2B for guiding the movement of the optional component supporter 7, and the optional component supporter 7 and the guided portion 7a guided by the optional component guide portion 2B, the movement of the optional component 7 and the PSx with respect to the base 2 can be smoothly and reliably performed. In addition, the guided portion PSx of the panel system PS itself also functions as an optional component support. In particular, since the guide portion 2B is a guide rail 2B formed along the extending direction of the base 2 and the guided portions 7a and PSx are insertion portions that can move along the guide rail 2B in a state of being inserted into the guide rail 2B, the guide portion 2B for the option component and the guided portions 7a and PSx can be realized with a simple structure, contributing to cost reduction.

In addition, the present invention is not limited to the above-described embodiments.

For example, the container CA shown in fig. 5 and 6 may be used as an optional component.

As shown in fig. 5 (in which fig. (a) and (b) are an overall schematic view and a side view of the storage CA), the storage CA includes: a storage device main body CA1 having a storage space CA1s therein, and a leg support CA2 for holding the storage device main body CA1 at a predetermined height position.

The container body CA1 has the storage space CA1s opened at least to the user side inside, and has a door CA11 capable of opening and closing the opening of the storage space CA1 s. In the present embodiment, although a structure capable of a flip operation is used as the door CA11, other doors (a double-slot sliding door type, a single-leaf single-opening type, a double-leaf double-opening type, a rolling shutter type, etc.) may be used. Further, as the container body CA1, a structure not provided with a door may be used.

The leg stay CA2 is a member whose tip end is fixed to the lower surface of the container body CA 1. Specifically, the leg stay CA2 is a member that supports a portion of the container body CA1 that serves as the center of gravity of the container body CA 1. In the present embodiment, the leg stay is fixed to a substantially central portion in the depth direction of the container body CA1 by an appropriate method. The container CA includes the leg stays CA2 as a pair on the left and right, and the stable support state of the container body CA1 is achieved by the leg stays CA 2. As shown in fig. 6, the height of each leg stay CA2 is set to be larger than the height of other optional members (for example, the screen panel EP).

In the case of such a storage container CA, a space CAs corresponding to the height dimension of the leg stay CA2 is formed below the storage container body CA1, so that other optional components (for example, the screen panel EP) can be disposed by using this space CAs, and various operation modes using various optional components can be flexibly handled.

In particular, when the storage tool CA is supported by the optional component support 7 guided by one guide rail 2b and the other optional components (for example, the screen panel EP) are supported by the optional component support 7 guided by the other guide rail 2b on the single base 2, when the optional component supports 7 are moved in the directions intersecting each other along the guide rails 2b in a state in which the storage tool main body CA1 and the other optional components are supported, the interference between the storage tool main body CA1 and the other optional components can be avoided and the operation of changing the relative positions between the storage tool CA and the other optional components can be smoothly and reliably performed.

As an optional component, a container CB shown in fig. 7 and 8 may be used.

The container CB is provided with: the storage device has a storage device body CB1 and a leg stay CB2 for holding the storage device body CB1 at a predetermined height position, and the storage device body CB1 has a storage space CB1s opened at least at a user side and a door CB11 capable of opening and closing the storage space CB1s, and in this regard, the mounting position (fixing position) of the leg stay CB2 to the storage device body CB1 is different from that of the storage device CA described above. That is, in the container CB, the leg stay CB2 is fixed to a portion (one end side along the depth direction of the container body CB 1) of the container body CB1 that is offset to the opposite side of the opening by an appropriate method.

When the storage tool CB is supported by the optional component support 7, the storage tool body CB1 is kept in a state of extending to the user side, therefore, in the case where the container CB is supported on the option part support 7 guided by one guide rail 2b and the option part support 7 guided by the other guide rail 2b on the single base 2, each container CB can be arranged in a state that the surfaces opposite to the open end of the container body CB1 are opposite (a state that the container bodies CB1 are back to back), and can prevent the mutual interference of the container bodies CB1 when moving in the mutually staggered direction, therefore, as shown in fig. 8, when the top boards 5 are arranged in the respective areas bounded by the base 2, the containers CB can be allocated to the respective users who use the top boards 5. Further, since the space CBs corresponding to the height dimension of the leg stay CB2 is formed below the container body CB1, other optional components (for example, the screen panel EP) can be disposed by using the space CBs, and various operation modes using various optional components can be flexibly handled, which is the same as the container CA.

Further, as the optional member support, the structure shown in fig. 9 and 10 may be used.

As shown in fig. 9 to 14, the optional member support 8 includes: a base portion 81 attachable to a lower end portion of the optional component (for example, a lower end portion of the leg stay CA2 of the container CA), an engaging portion 82 engageable with the convex portion 2ba of the guide rail 2b, a pressing portion 83 press-contacted to the upper surface portion 22 of the guide rail 2b to press the upper surface portion 22 of the guide rail 2b, and a rolling body 84 attachable to the bottom wall 2bb of the guide rail 2 b. The convex portions 2ba provided on the guide rails 2b protrude in a direction to reduce the size of the opening of the guide rails 2 b. In the present embodiment, each of the convex portions 2ba is formed over a region extending from the upper surface portion 22 of the base 2 to a substantially central portion in the height direction of the guide rail 2b or a region offset to the lower side than the substantially central portion in the height direction, and a recessed slide cover holding portion 2bax for slidably holding a slide cover (not shown) is formed on the upper end portion side of the convex portion 2 ba.

The base portion 81 is a member having a substantially flat plate shape and capable of being fixed to the lower end portion of the optional member by a fixing method such as bolt fastening or welding.

The engaging portion 82 is attached to the base portion 81 and is movable between an engageable position where it engages with the convex portion 2ba provided on the guide rail 2b and an disengageable position where it cannot engage with the convex portion 2 ba. In the present embodiment, a pair of engaging portions 82 that can be inserted into the adjacent guide rails 2b are provided, and the engaging portions 82 are rotatable about horizontal axes around a rotation axis 82x provided on the base portion 81. More specifically, at the lower end of each engaging portion 82, an engaging claw 82a is provided which is engageable with the downward surface 2bay of the convex portion 2ba, and the tip ends of the engaging claws 82a project in directions away from each other. In the present embodiment, although the urging member 85 (spring or the like) urging each engaging portion 82 to the engageable position is provided between the upper end portions of the engaging portions 82, even when the urging member 85 does not act, the engaging portions 82 are positioned at the engageable position by their own weight by providing the rotation shaft 82x at a position shifted from the center of gravity.

The pressing portion 83 is a member that can move up and down with respect to the base portion 81. In the present embodiment, the pressing portion 83 is provided as a multi-layer member having a pressing plate 83a directly pressed by a cam surface of an eccentric cam 86a provided at a lower end portion of an operating lever 86, which will be described later, and a resinous pressing pad 83b integrally provided on a downward surface of the pressing plate 83a and directly contacting the upper surface portion 22 of the guide rail 2 b.

The rolling elements 84 are movable between a splicing position where they are spliced to the bottom wall 2bb of the guide rail 2b and a splicing release position where they are separated from the bottom wall 2bb of the guide rail 2 b. In the present embodiment, the rolling elements 84 are attached to the lower end portions of the tabs 811 integrally provided on the base portion 81 so as to be rotatable about a horizontal axis.

The optional member holder 8 in the present embodiment includes an operating lever 86 rotatable about a horizontal axis about a rotation axis 86x provided on the base portion 81. The operating lever 86 is a member including a grip portion 86b that can be gripped by a user and an eccentric cam 86a provided on the rotation base end side. Further, the operating lever 86 includes an engaging portion operating body 86c which is fitted between the upper end portions of the pair of engaging portions 82 and moves each of the engaging portions 82 from the engageable position to the disengaged position against the biasing force of the biasing device 85 in a process of changing the posture of the operating lever 86 from the upright posture in which the operating lever is erected substantially vertically to the collapsed posture in which the operating lever is rotated by about 90 degrees. In the present embodiment, as the engaging section actuating member 86c, a substantially rod-shaped member having a dimension larger than the dimension of the space between the inward surfaces of the engaging sections 82 is used.

Then, the optional member supporter 8 in the present embodiment is configured by the operating rod 86, the engaging portion 82, the rolling elements 84, and the like, and is configured as a switching mechanism 8X that can be switched between a movement-permitted state in which the movement of the optional member supporter 8 with respect to the guide rail 2b is permitted and a movement-permitted state in which the movement of the optional member supporter 8 with respect to the guide rail 2b is permitted.

When the switching mechanism 8X is in the movement restriction state, the engagement portion 82 is located at the engageable position, and the rolling elements 84 are located at the engagement release position (see fig. 11 and 12). On the other hand, when the switching mechanism 8X is in the movement-permitted state, the engagement portion 82 is located at the engagement release position, and the rolling elements 84 are located at the engageable position (see fig. 13 and 14).

Next, a method of using the optional component support 8 and its operation will be described.

When the optional member holder 8 is moved along the guide rail 2b, the switching mechanism 8X needs to be switched from the movement restricted state to the movement permitted state. This switching operation is performed by applying an operation force for changing the posture of the operating lever 86 in the upright posture to the collapsed posture. Based on this operating force, the base part 81 is lowered toward the pressing part 83 by the action of the eccentric cam 86a provided at the lower end part of the operating lever 86, and the optional member, the engaging part 82, and the rolling element 84 integrally provided on the base part 81 are also lowered together with the base part 81 (that is, a space 81s for allowing the eccentric cam 86a to rotate is formed in the base part 81). As a result, the rolling elements 84 are positioned at the joinable position where they are joined to the bottom wall 2bb of the guide rail 2b, the engaging portion operating bodies 86c of the operating lever 86 are fitted between the upper end portions of the engaging portions 82, and the engaging portions 82 are rotated about the rotation axis and positioned at the engagement release position where the engaging claws 82a are separated from the convex portions 2ba of the guide rail 2b (see fig. 13 and 14). Both end portions of the engaging portion operating body 86c are temporarily engaged and held in the recessed portions 82b (see fig. 12) provided in the upper end portion of the engaging portion 82. By switching the switching mechanism 8X from the movement restricting state to the movement permitting state in this way, the optional component holder 8 can be moved along the extending direction of the guide rail 2b in a state of holding the optional component. In addition, in a state where each of the engagement portions 82 is at the engagement release position, the engagement portion 82 is in an inclined posture, and as shown in fig. 15, when the optional member 8 is moved in the opening direction (upward) of the guide rail 2b in this posture, the engagement claw 82a is set so as not to interfere with the convex portion 2ba of the guide rail 2 b. Thus, by setting the switching mechanism 8X to the movement-permitted state, the optional component holder 8 can be inserted and removed along the opening direction of the guide rail 2b, and the operation of attaching and detaching the optional component holder 8, and thus the optional component to and from the guide rail 2b can be performed.

On the other hand, when the relative arrangement position of the optional component (for example, the container CA) with respect to the base 22 is fixed, the switching mechanism 8X needs to be switched from the movement-permitted state to the movement-restricted state. This switching operation is performed by applying an operation force for changing the posture of the operating lever 86 in the collapsed posture to the upright posture. Based on this operating force, the pressing portion 83 is pressed downward by the action of the eccentric cam 86a provided at the lower end portion of the operating lever 86, the base portion 81 rises relative to the pressing portion 83, and the optional member, the engaging portion 82, and the rolling elements 84 integrally provided on the base portion 81 also rise relative to the pressing portion 83 together with the base portion 81. As a result, the rolling elements 84 are positioned at the engagement release position separated from the bottom wall 2bb of the guide rail 2b, and the engaging portion operating bodies 86c temporarily engaged and held in the recessed portions 82b of the respective engaging portions 82 are released from the engaged state and separated from between the upper end portions of the respective engaging portions 82, the engaging portions 82 are rotated about the rotation shaft 82x to be positioned at the engageable position where the engaging claws 82a are engaged with the projecting portions 2ba (more specifically, the lower surface 2bay) of the guide rail 2b, and the projecting portions 2ba of the guide rail 2b are pressed in the compression direction by the engaging claws 82a and the pressing portions 83 (see fig. 11 and 12). In this state, the substantially central portion of the pressing portion 83 is pressed against a portion of the upper surface portion 22 of the base 2 corresponding to the portion between the guide rails 2 into which the engaging portions 82 are inserted. By switching the switching mechanism 8X from the movement-permitted state to the movement-restricted state in this way, the optional component holder 8 and further the optional component (such as a storage tool) can be firmly fixed to the base 2, and a stable supported state can be achieved.

In the present embodiment, the pair of option member supporters 8 facing each other at the position spaced by the predetermined dimension are connected by the connecting body 8R, and not only is a more stable supported state realized, but also the movement of each option member supporter 8 with respect to the base 2 is interlocked to perform the movement more smoothly. The dimension of the space between the pair of option member supports 8 is made to correspond to the width dimension of the option member (e.g., the dimension of the space between the pair of leg stays CA2 of the storage fixture CA).

The optional component support 8 described above is supported on the base 2 by the 2-row guide portions (the guide rails 2b), but may be supported on the base 2 by a single guide portion (the guide rail 2 b). The following examples are given as examples thereof.

As shown in fig. 16 to 20, the optional component support 9 includes: a main body 91 having a thickness dimension smaller than the minimum opening dimension of the guide rail 2 b; a base portion 92 provided at an upper end portion of the main body portion 91 and to which a lower end portion of an optional component (for example, a lower end portion EP1 of the screen panel EP) is attachable; an engaging portion 93 engageable with the convex portion 2ba of the guide rail 2 b; a pressing portion 94 which is pressed against the upper surface portion 22 of the guide rail 2b (upward surface including the convex portion 2 ba) and can press the upper surface portion 22 of the guide rail 2 b; and rolling bodies 95 capable of being spliced on the bottom wall 2bb of the guide rail 2 b. As shown in fig. 18, the convex portions 2ba provided on the guide rails 2b protrude in a direction in which the opening size of the guide rails 2b is reduced. In the present embodiment, each of the convex portions 2ba is formed in a region extending from the upper surface portion 22 of the base 2 to a substantially central portion in the height direction thereof or offset downward from the substantially central portion in the height direction, and a recessed slide cover holding portion 2bax capable of slidably holding a slide cover, not shown, is formed on an upper end portion side of the convex portion 2 ba.

The main body 91 includes: a main body 911 having a space of a predetermined size therein, and a movable body 912 provided inside the main body 911 and movable up and down with respect to the main body 911. In the present embodiment, a plate-like member having a substantially downward コ shape in side view is used as the movable body 912. The movable body 912 is biased upward by a movable body biasing member 913 provided in the main body 911. Further, an internal space 911s (see fig. 17) that allows vertical movement of the movable body 912 is formed in the main body portion 911.

The base portion 92 is a member having a substantially flat plate shape and is fixable to the lower end portion of the optional member by a fixing method such as bolt fastening or welding. In the present embodiment, the base portions 92 are provided in pairs at positions spaced apart by a predetermined distance in the longitudinal direction of the body portion 91.

The engaging portion 93 is attached to the main body portion 91, and is constituted by a pair of engaging members 931 arranged in opposition to each other so as to be capable of opening in a substantially inverted-V shape and disposed at positions where the movable body 912 can be sandwiched (see FIG. 18). Each engaging member 931 is movable between an engageable position in which it engages with the convex portion 2ba provided on the guide rail 2b and an engageable release position in which it cannot engage with the convex portion 2 ba. In the present embodiment, the engagement portions 93 formed of the pair of engagement pieces 931 are provided in pairs at positions spaced apart by a predetermined distance in the longitudinal direction of the main body portion 91 (see fig. 16 and 17). Each fitting 931 is rotatable about a horizontal axis about a rotation axis 931x provided in the main body 91. More specifically, a rotating shaft 931x is provided at the lower end of each fitting 931, a fitting claw 931a capable of fitting (contacting or pressure-contacting) with the downward surface 2bay of the convex portion 2ba is provided at a portion displaced upward from the rotating shaft 931x by a predetermined dimension, and the tip ends of the fitting claws 931a are projected in directions away from each other. In the present embodiment, although the fitting urging member 932 (such as a spring) for urging each fitting 931 to the engageable position is provided between the lower end portions of the fittings 931, each fitting 931 can be positioned at the engageable position by its own weight by providing the rotating shaft 931x at a position offset from the center of gravity even when the urging member 932 does not function.

The pressing portion 94 is provided in association with an operating lever 96 described later, and will be described later in detail.

The rolling element 95 is a member movable between a splicing position where it can be spliced to the bottom wall 2bb of the guide rail 2b and a splicing release position where it is separated from the bottom wall 2bb of the guide rail 2 b. In the present embodiment, the rolling element 95 is attached to the lower end portion of the body 91 so as to be rotatable about a horizontal axis.

The optional component holder 9 in the present embodiment includes an operation lever 96 that is rotatable about a horizontal axis about a rotation axis 96x provided on the main body 91. The operation lever 96 is mainly composed of an operation lever body 961 including a grip portion 961a that can be gripped by a user and a guide rail pressing eccentric cam 961b provided on a rotation base end side. The guide rail pressing eccentric cam 961b functions as the pressing portion 94. In the present embodiment, the pair of plate-shaped operation lever main bodies 961 are opposed to each other in the thickness direction, and a body 962 to be gripped having a movable body pressing eccentric cam 962a capable of pressing the movable body 912 of the main body portion 91 at the lower end portion is sandwiched between the operation lever main bodies 961. The body 962 to be gripped rotates about the rotation axis 96x together with the operation lever main body 961.

Next, the optional member holder 9 of the present embodiment is configured by the operating lever 96, the movable body 912, the engaging portion 93, the rolling body 95, and the like, and is configured as a switching mechanism 9X that can be switched between a movement-permitted state in which the optional member holder 9 is permitted to move relative to the guide rail 2b and a movement-permitted state in which the optional member holder 9 is permitted to move relative to the guide rail 2 b.

When the switching mechanism 9X is in the movement restriction state, each of the engaging elements 931 of the engaging portion 93 is located at the engageable position, and the rolling element 95 is located at the engagement release position (see fig. 17 and 18). On the other hand, when the switching mechanism 9X is in the movement-permitted state, each of the engaging elements 931 of the engaging portion 93 is located at the engagement release position, and the rolling element 95 is located at the engageable position (see fig. 19 and 20).

Next, a method of using the optional component holder 9 and its operation will be described.

When moving the optional member holder 9 along the guide rail 2b, the switching mechanism 9X needs to be switched from the movement restricting state to the movement permitting state. This switching operation is performed by applying an operation force for changing the posture of the operation lever 96 in the collapsed posture to the upright posture. Based on this operating force, the movable body 912 is pushed downward against the biasing force of the movable body biasing member 913 by the action of the movable body biasing eccentric cam 962a provided at the lower end portion of the clamped body 962 of the operating lever 96, and the movable body 912 is lowered relative to the main body 911 and enters between the lower end portions of the mating pieces 931 of the mating portions 93. Then, each fitting 931 pivots about the rotation shaft 931x in a direction to bring the fitting claws 931a closer to each other against the biasing force of the fitting biasing member 932, and moves to the above-described fitting release position where the fitting claws 931a are separated from the convex portions 2ba of the guide rail 2 b. Further, based on the above-described operation force, the state of pressing the guide rail pressing eccentric cam 961b (pressing portion 94) against the upper surface portion 22 of the base 2 (including the upward surface of the convex portion 2 ba) is released, and the entire optional component holder 9 is lowered. As a result, the rolling elements 95 are positioned at the joinable positions where they are joined to the bottom wall 2bb of the guide rail 2b (see fig. 19 and 20). By switching the switching mechanism 9X from the movement restricting state to the movement permitting state in this way, the optional component holder 9 can be moved along the extending direction of the guide rail 2b in a state of holding the optional component. Further, each of the fitting pieces 931 located at the engagement release position is set in a substantially vertical posture such that the fitting claw 931a does not interfere with the convex portion 2ba of the guide rail 2b when the optional member holder 9 is moved in the opening direction (upward) of the guide rail 2b in this posture. Thus, by setting the switching mechanism 9X to the movement-permitted state, the optional component holder 9 can be pulled out and inserted in the opening direction of the guide rail 2b, and the operation of attaching and detaching the optional component holder 9, and thus the optional component to and from the guide rail 2b can be performed.

On the other hand, when the relative arrangement position of the optional member with respect to the base 22 is fixed, the switching mechanism 9X needs to be switched from the movement-permitted state to the movement-restricted state. This switching operation is performed by applying an operation force for changing the posture of the operating lever 96 in the upright posture to the collapsed posture. Based on this operation force, the pressing state of the movable body pressing eccentric cam 962a with respect to the movable body 912 is released, and the movable body 912 is lifted up relative to the main body portion 911 by the biasing force of the movable body biasing member 913, and is separated from between the lower end portions of the mating pieces 931 of the respective mating portions 93. Then, each fitting 931 is rotated about the rotation shaft 931x by the biasing force of the fitting biasing member 932, in a direction in which the fitting claws 931a are opened from each other, and is moved to the engageable position where the fitting claws 931a can be engaged (brought into contact with or pressed against) the convex portion 2ba (more specifically, the downward surface 2bay) of the guide rail 2 b. Further, based on the operation force, the rail pressing cam 961b (pressing portion 94) presses the upper surface portion 22 (upward surface including the convex portion 2 ba) of the base 2, and the entire optional component holder 9 is raised by the so-called lever principle with the upper surface portion 22 (upward surface including the convex portion 2 ba) of the base 2 as a fulcrum. As a result, the convex portion 2ba of the guide rail 2b is clamped in a state of being pressed in the compression direction by the engaging claw 931a and the guide rail pressing cam 961b (pressing portion 94), and a fastened state is achieved (see fig. 17 and 18). By switching the switching mechanism 9X from the movement-permitted state to the movement-restricted state in this way, the optional component holder 9, and thus the optional component, can be firmly fixed to the base 2, and a stable supported state can be achieved.

In the present embodiment, the main body 91 is provided with an auxiliary rolling element 914 rotatable about a vertical axis, and a contact portion 915 contactable with the bottom wall 2bb of the guide rail 2 b.

By providing the optional component supports 8 and 9 of different types so as to be attachable to the base 2, it is possible to appropriately select the type (optional component support 8) supported on the base 2 by the guide portions (guide rails 2b) of the 2 rows or the type (optional component support 9) supported on the base 2 by the single guide portion (guide rail 2b) in accordance with the weight of the optional component or the like.

As optional components, a desk top, a power outlet, a wire storage device, a telephone stand with a stand, a tray, a bookshelf, a display stand, and the like can be used.

The optional member support may be supported so as to be movable with respect to the base, and may be supported so as to be movable in a stepless manner, as in the above-described embodiment, or may be supported so as to be movable so as to be capable of being stopped at predetermined intervals in a regulated manner, or may be moved in a state in which a sliding contact member or a contact member provided in the optional member support is brought into sliding contact or contact with a guide portion of the base, instead of utilizing the sliding movement of the rolling elements.

Alternatively, a single or a plurality of bases may be arranged in a substantially L-shaped, substantially T-shaped, or substantially cross-shaped plan view, and the optional member support may be supported so as to be movable in a plurality of directions along the bases. In the above-described embodiment, the case where the base extends linearly is exemplified, but the present invention is not limited to this, and the base may extend in a curved shape (circular curved shape, elliptic curved shape) or may extend in a meandering shape.

In addition, if a locking device that restricts the movement of the optional component support with respect to the base is provided, it is possible to prevent the accidental movement of the optional component.

Further, a stopper for stopping the horizontal rotation angle of the optional component in a regulated manner at every predetermined angle may be provided between the optional component and the optional component support. In addition, in the case where the option member is horizontally rotatably supported on the option member support, if a rotation lock device capable of switching between a horizontal rotation allowed state in which horizontal rotational movement of the option member is allowed and a horizontal rotation restricted state in which horizontal rotational movement of the option member is restricted is provided between the option member and the option member support, it is possible to prevent accidental rotational movement of the option member.

The guide rail constituting the guide portion may be either a groove-like or a projection-like guide rail, and the number thereof may be increased or decreased as appropriate. Further, as the guide portion and the guided portion, a structure other than the guide rail or the insertion portion may be used. Further, a plurality of optional component supports may be supported on a single base. In this case, if the optional component support is detachably supported on the base by an appropriate method, the number of optional component supports supported on the base can be selected in accordance with the number of optional components required by the worker himself. In this case, for example, in the above embodiment, it is also possible to form an entire desk having the panel system PS, the work light TL, and the enclosure panel EP with respect to the single base 2.

In the case where a plurality of desks are disposed so as to be continuous in the longitudinal direction of the plurality of bases, it is preferable that the optional component support provided movably on one base is movable from the one base to another base adjacent thereto. In this case, the optional component supported by the optional component support can be moved from one base to another adjacent base, and the degree of freedom of the location where the optional component is disposed can be further improved. In this case, if the through portions for allowing the optional component holder to pass through are provided at both end portions of the base or the end caps attached to both end portions of the base, it is possible to ensure good movement of the optional component holder. Examples of the allowing portion include a guide portion provided on the base, and a notch or a slit formed in a portion of the end cover corresponding to the guide portion.

The top plate may be supported by the top plate support so as not to be horizontally rotatable, supported by simply being placed on the top plate support, or supported by one or more legs without being supported by the base and the top plate support, and independent from the base. The top plate may have a shape in plan view of various shapes such as a circular shape, an elliptical shape, or a polygonal shape, in addition to the gourd shape or the rectangular shape shown in the above embodiments.

As shown in fig. 4(b), a desk having a plurality of top boards for a single base may be used depending on the business form, the content of the work, the number of people, and the like.

In addition, as the base, instead of the structure in which both end portions are supported on the base support and the lower surface portion is separated (suspended) from the ground surface, a standing wall-like structure may be used in which the lower surface portion of the base is in contact with the ground surface and can also function as a shroud.

The specific configuration of each part is not limited to the above embodiment, and various modifications may be made without departing from the scope of the present invention.
