Description

  The present invention relates to a top board for a desk that can be used in various forms in an office or the like and realizes an easy wiring operation in response to the use form.

A group of desks with multiple islands facing each other is placed on the office floor to form a general worker's office seat, and the opposite end of another desk is brought into contact with the side edge of the desk group. In some cases, an office layout that forms manager's office seats is adopted, but in recent years, a large table type desk has been replaced by one island in order to eliminate the adverse effects of using many desks in such an office layout. It has come to be used as a reference. Such a desk is configured so that the user's seat layout can be easily changed according to the use of a plurality of workers for work, meetings, projects, etc. The edge side and the rear edge side can be used as office seats for general workers, and the side edge side of the top board can also be used as a manager's office seat. In addition, since computer work is often performed on the top board, a wiring insertion path that communicates with the wiring space below the top board in order to deliver wiring such as communication cords and power cords up and down the top board. May be formed (see, for example, Patent Document 1). Furthermore, if such a wiring insertion path is left open on the top board, it is assumed that small objects such as pens fall from the wiring insertion path to the bottom of the top board. A wiring cover that can be selectively opened and closed is attached, and only when performing wiring work, the wiring cover is opened to open the wiring insertion path (for example, see Patent Document 2). Such a wiring cover is pivotally attached to a rotating shaft that spans the wiring insertion path along the width direction of the top plate, and a worker who works on the front and rear edges of the top plate opens and closes the wiring cover. Generally, it is configured so that the operation is easy.

  However, when the wiring cover is attached to the existing rotary shaft on the top board in this way, it is easy for workers who use the top board from the front edge side or the rear edge side to open and close the wiring cover, but the side edge of the top board. However, if the manager seat is formed as a use edge, the operation part of the wiring cover is located far from this manager, the opening / closing direction of the wiring cover is different between the case of a general worker and the case of the manager, and the wiring cover is opened. Even in such a state, the manager cannot obtain a large opening of the wiring insertion path, and various problems arise that the layout of the wiring cover cannot be changed so as to be easy to use in response to the seat layout change. Further, since the rotating shaft is fixed to the top plate in the wiring insertion path, the presence of the rotating shaft itself becomes an obstacle to wiring work.

  Therefore, in view of the above problems, the present invention provides a top plate that can use the front and rear edges and side edges of the desk top as usage edges. The main object is to provide a top plate capable of appropriately changing the arrangement mode of the wiring cover so that the wiring work can be easily performed.

That is, the top plate according to the present invention can be attached to and detached from the top plate body so as to partially block the wiring board passage formed by communicating with the top plate body and the wiring space formed below the top plate body. A wiring cover to be mounted, and the top plate body is constituted by a pair of top plate elements that are arranged with the opposite use edges facing each other, and the use edge of any one of the top plate elements is fixed to the top. It is the top plate of the desk which makes it the said front edge of a board main body, and uses the use edge of the other top plate element as the said rear edge of a top plate main body . In other words, the top plate according to the present invention is a layout in which workers work facing each other facing the front and rear edges, a layout in which a worker's seat is formed only on either one of the front and rear edges, or a seat only on the side edges. The seat layout can be changed at any time according to the mode of use, such as the layout that forms the seat, the layout that forms the seat on both the front and rear edges or one and the side edges, and in response to such a layout change It is allowed to attach one or a plurality of wiring covers to one wiring insertion path. And, on the counter-use edge of each top plate element, a notch portion cut out in a substantially rectangular shape so as to open outward is formed, and the notch portion among the gaps between each notch portion and each top plate element A wiring insertion passage having a substantially square shape in plan view is constituted by a portion in between, and by changing the horizontal mounting angle of the wiring cover with respect to the wiring insertion passage having a substantially square shape in plan view , A first mounting mode that can take a standing posture that opens the wiring insertion path toward the edge or the rear edge, and a second mounting mode that can take a standing posture that opens the wiring insertion path toward the side edge of the top plate body. And can be mounted on the top plate body.

  With the top plate having such a configuration, in various seat layouts as described above, when the seat is formed mainly using one or both of the front and rear edges of the top plate body, the wiring cover is not used. If the side edge is used as a working edge, such as being attached to the top plate body in the first mounting mode, or forming a manager seat on the side edge side of the top plate, the wiring cover is attached to the top plate body in the second mounting mode. By mounting, the worker can operate the wiring cover from the seat on the use edge side in each seat layout to open the wiring insertion path and easily perform the wiring work. Further, when the use edge of the top board is appropriately set to the front and rear edges or the side edges corresponding to the meeting or project, the wiring cover is selected from the first and second mounting modes according to the layout. A person who can easily access the wiring insertion path through the operation of the is selected and attached to the top plate body. In other words, according to the present invention, since it is possible to select an arrangement mode of the wiring cover that can open the wiring insertion path in response to the use state of the top board accompanying the change of the seat layout, a top board that is very easy to use for wiring work can be selected. Can be realized.

  In the above top plate, when the wiring work is not performed, the top surface of the top plate can be used widely and the small objects are prevented from falling into the wiring space, and the wiring insertion path is opened widely only when the wiring work is performed. In order to be able to do so, in both the first mounting mode and the second mounting mode, the wiring cover has a lying posture in which the upper surface thereof is substantially flush with the upper surface of the top plate body, and the open end side thereof. It is attached to the top plate body so that either of the standing posture that projects upward from the top surface of the top plate body and opens the wiring insertion path can be selectively taken with the rotation operation with respect to the top plate body. It is desirable to configure.

  In this case, the operability is improved without providing a protrusion on the upper surface side of the wiring cover, and the wiring cord can pass between the upper surface side of the top plate and the wiring insertion passage even when the wiring cover is in a lying posture. In order to achieve this, an operation portion capable of operating the rotation operation of the wiring cover in the lying posture and inserting the wiring cord passing through the wiring insertion path is partially cut out at the front edge of the wiring cover. It is preferable to form them.

  In addition, in order to prevent the wiring insertion path from being unduly narrowed depending on the support structure while maintaining the stable mounting state of the wiring cover to the top board body, Providing a cover receiving part having a drop-off prevention piece that protrudes from the lower edge inward without blocking the wiring insertion path to prevent the wiring cover from falling off, and lays down the wiring cover in the first mounting mode and the second mounting mode It is good to comprise so that it may mount in a fall-off prevention piece in a posture.

  Furthermore, in order to make the operation smooth while stably supporting the wiring cover, and to prevent the wiring insertion path from being unduly narrowed even by the configuration for the operation of the wiring cover, the cover A rotation support piece serving as a fulcrum of a rotation operation between the lying posture and the standing posture of the wiring cover in the first mounting mode and the second mounting mode is provided on the receiving portion. It is effective to contact the peripheral wall of the wiring insertion path. In order to effectively prevent the wiring cover from dropping even in the standing posture, the wiring covers in the first mounting mode and the second mounting mode are placed on the rotation support piece in the standing posture. What should I do?

The present invention also provides a wiring that is detachably attached to the top plate body so as to partially block a wiring insertion passage formed by communicating with the top plate body and a wiring space formed below the top plate body. And a top plate of a desk that can use either one or both of the front edge or the rear edge and a side edge as a working edge, and the wiring cover is mounted at a horizontal mounting angle with respect to the top plate body. By changing the first mounting mode, the wiring insertion path can be opened toward the front edge or the rear edge of the top board body, and the wiring insertion path is opened toward the side edge of the top board body. This is based on the premise that any one of the obtained second mounting modes can be selected and mounted on the top plate body. Based on such premise, the top plate whose seat layout can be changed as described above is composed of a pair of top plate elements that are arranged with the anti-use edges facing each other as the top plate body, and whichever The use edge of one top plate element is used as the front edge of the top plate body, and the use edge of the other top plate element is used as the rear edge of the top plate body. The front edge can be used as a use edge by associating the front edge with the side edge of the top plate body that is detachably disposed across the outer edge of the plate element and is constituted by the side edges of the top plate elements. Some have an auxiliary top plate that is separate from the top plate body. In such a top plate, by forming a wiring insertion path at a position along the counter-use edge at the position opposite to the use edge of the auxiliary top plate on the counter-use edge side of the pair of top plate elements, Operation for the wiring cover and access to the wiring insertion path can be made easy for both the person who uses the front and rear edge sides as the seat and the person who uses the front edge side of the auxiliary top plate as the seat.

  Specifically, in the top plate of such an aspect, as a configuration for facilitating the operability with respect to the wiring cover and the accessibility to the wiring insertion path and the wiring space, a pair of top plate elements are arranged between their counter-use edges. A gap of a predetermined width is disposed between the wiring board, and a wiring insertion path is formed on the gap between the top board elements and on the counter-use edge side of the pair of top board elements and the auxiliary top board so as to communicate with the gap. The thing comprised by each notch part is mentioned.

  In this case, the wiring cover is accommodated in the notch portion of the top plate element in the first mounting mode, and is configured to be accommodated in the notch portion of the auxiliary top plate in the second mounting mode. It is possible to improve the appearance of the top plate while maintaining the integrity of the gap between them. In particular, in order to minimize the number of wiring covers and prevent unnecessary gaps between the top plate elements and the wiring covers, all the notches have substantially the same shape. The cover preferably has a width dimension and a depth dimension corresponding to the inner width dimension and the inner depth dimension of each notch.

  In addition, as a mode in which a plurality of wiring covers can be suitably disposed in the wiring insertion path and the operation of each wiring cover does not hinder the operation of other wiring covers, the wiring cover is less than half of the wiring insertion path. And having a leading edge along the wiring insertion path. For example, when both the front and rear edges of the top plate are used edges, the wiring cover is arranged opposite to the wiring insertion path so that persons on both sides of the front and rear edges can individually perform the wiring work. It is effective for.

  According to the present invention, in a top board that can change a seat layout such as a general island-type arrangement of seats, an arrangement for providing a manager's seat, and a seat arrangement at a meeting or a project, with a single desk. When the seat is formed using either one or both of the front and rear edges of the plate body as a use edge, the wiring cover is attached to the top plate body in the first attachment mode, and the side edge side of the top plate is mainly used as the use edge. When forming a seat, it is possible to change the mounting mode of the wiring cover with respect to the top plate body, such as mounting the wiring cover on the top plate body in the second mounting mode. As a result, the worker can operate the wiring cover from the seat on the use edge side corresponding to each seat layout to open the wiring insertion path and easily perform the wiring work. Therefore, according to the present invention, there is provided a top plate that is extremely excellent in wiring workability in that it is possible to select an arrangement mode of the wiring cover that can open the wiring insertion path regardless of the use situation of the top plate accompanying the change of the seat layout. It is possible to provide.

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

  The top board T according to this embodiment is a top board in a large table X that is a kind of desk that can be used by changing the seat position as appropriate for purposes such as island-type staff placement, staff placement at meetings or projects, etc. T. That is, in this table X, not only the front and rear edges of the top plate T can be used as the use edges, but also the side edges can be used as the use edges. The table X is mainly composed of a top plate T, support legs F that support the top plate T, and a wiring duct D that is disposed below the top plate T and accommodates an outlet box and cords. is there.

  Here, parts other than the top plate T in the table X will be briefly described. First, the support legs F support the front and rear of both side edges of the top plate T from below, and a well-known one having an adjuster at the lower end is applied. Further, an intermediate leg (not shown) is provided at a substantially central portion of the top board T, and the top board T is supported by these legs and a frame (not shown). Further, the wiring duct D has a wiring space DS opened upward, and the counter-use edge T1b of the top plate element T1 that makes a pair in the front-rear direction as will be described later, that is, the center portion in the depth direction of the top plate T. It is arranged below. And the wiring cover 2 is arrange | positioned in the position which can cover the said wiring space DS from upper direction. The wiring duct D is partially formed with a hole that opens the wiring space DS downward (not shown).

  Here, the top plate T includes a top plate body T0 including a plurality of top plate elements T1, a wiring cover 2 and an auxiliary top plate 6 which will be described later. Each top plate element T1 is made of a plate material having a substantially rectangular shape in plan view, and a front edge positioned on a long side on which a worker is seated is a use edge T1a, and an opposite side is a counter use edge T1b. Then, the top plate elements T1 are arranged as a set, and the opposite use edges T1b at the opposite positions of the use edges T1a in both the top plate elements T1 are arranged to face each other, and further, on the side edges T1c of each top plate element T1 By arranging the side edges T1c of another pair of top plate elements T1 in contact with or close to each other, the counter-use edge T1b of each top plate element T1 is placed at the center in the depth direction of the entire top plate body T0. The used edges T1a of the top plate elements T1 are positioned at both ends in the depth direction. In short, this top plate body T0 has a plurality of top plate elements T1 arranged in a matrix, and uses the use edge T1a of each top plate element T1 which becomes the front edge or the rear edge of the top plate body T0 as the use edge. The side edge T1c of the top plate element T1 opened outward can also be used as a use edge. The pair of front and rear top plate elements T1 are arranged with a gap TS having a predetermined width between the counter-use edges T1b. The gap TS communicates with the wiring space DS of the wiring duct D, and the width thereof is set to a width that allows the cords C such as a LAN cable and a wiring cord to be inserted.

  A notch TK that forms part of the wiring insertion path S of the present invention that communicates with the wiring space DS of the wiring duct D is formed at the counter-use edge T1b of each top plate element T1. Each notch TK is a substantially rectangular notch so as to open a substantially central portion of the counter-use edge T1b of the top plate element T1 outward, and is formed so as to communicate with the gap TS. ing. A wiring insertion path S having a substantially square shape in plan view is formed by the notches TK formed in the pair of front and rear top plate elements T1 and the portions between the notches TK in the gap TS (shown by imaginary lines in FIG. 2). (See the figure). Further, the wiring cover 2 is disposed so as to partially block the wiring insertion path S. The wiring cover 2 will be described in detail later.

  Thus, although the top-plate main body T0 can utilize the use edge T1a of each top-plate element T1 as a use edge, it is also possible to use the side edge T1c as a use edge. However, in this case, since the gap TS between the top plate elements T1 extending forward from the front of the user on the side edge T1c side is formed, it may be difficult to use. Therefore, in the present embodiment, as shown in FIG. 10, the auxiliary TS 6 is detachably mounted on the outer end side of the pair of front and rear top elements T1 so as to cover the gap TS and newly use the same. A seat having a surface can be formed.

It is suitable when forming.

  Here, the auxiliary top plate 6 is arranged so as to straddle the outer end portions of the pair of top plate elements T1 in which the counter-use edges T1b are arranged to face each other. Specifically, the auxiliary top plate 6 has a thin plate shape having a width dimension substantially corresponding to the front-rear dimension of the top plate body T0, and is a top plate body X0 constituted by side edges T1 of a pair of front and rear top plate elements T1. By making the front edge correspond to the side edge and making the side edge 6c correspond to the use edge T1a of each corresponding top plate element T1, the front edge 6a can be used as the use edge. A cutout portion 6K having substantially the same shape as the cutout portion TK of each top plate element T1 is formed at a substantially central portion of the counter use edge 6b of the auxiliary top plate 6. Then, in a state where the auxiliary top plate 6 is slid from the side of the top plate T toward the inside and attached to the top plate T, the notch portions 6K of the auxiliary top plate 6 are notched portions of the pair of top plate elements T1. It matches with TK. That is, in a state where the auxiliary top plate 6 is mounted on the top plate body T0, the long side and the short side of the notch portion 6K in the auxiliary top plate 6 are aligned with the short side and the long side of the notch portion TK in the top plate element T1, respectively. Then, the wiring insertion passage S having the same shape is formed at the same location as the wiring insertion passage S formed by the pair of front and rear top plate elements T1.

  The wiring cover 2 is formed so as to partially block the wiring insertion passage S formed in the top plate body T0 or the wiring insertion passage S formed with the auxiliary top plate 6 attached to the top plate body T0. Mounted on the top plate body T0. At that time, as shown in FIGS. 1 to 3, the wiring cover 2 has a first mounting mode P or a top plate element T1 that can open the wiring insertion path S toward the use edge T1a of the top plate element T1.

  First, by placing the wiring cover 2 on the protruding piece 32 from above the notch TK of the top plate element T1, the wiring cover 2 assumes the lying posture (FIGS. 2 and 9A). In this lying down posture, the rear extending piece 53 of the backing member 5 and the lower end of the second hanging piece 54 are in contact with the protruding piece 32 of the cover receiving portion 3 to prevent the wiring cover 2 from falling off. Thus, the protruding piece 32 of the cover receiving portion 3 functions as a drop-off preventing piece. Further, in the lying posture, the stepped portion 54D of the second hanging piece 54 comes into contact with or comes close to the first convex portion 33b provided on the first standing piece 33 of the cover receiving portion 3, and a more stable placement state is obtained. In this lying down posture, the cords C are set to be able to be inserted using a gap between the operation portion 2a formed on the front edge of the wiring cover 2 and the notch TK of the top plate element T1. In order to set the wiring cover 2 in the lying posture to the intermediate posture, a worker puts his finger on the operation portion 2a of the wiring cover 2 and the first convex portion of the first standing piece 33 provided on the cover receiving portion 3 The wiring cover 2 is rotated to the counter-use edge T1b side of the top plate element T1 using 33b as a fulcrum. As the wiring cover 2 rotates, the step portion 54D formed on the second hanging piece 54 of the backing member 5 engages with the concave portion 33a provided on the first upright piece 33 of the cover receiving portion 3, and the wiring cover The wiring cover 2 is in the intermediate position by temporarily resting 2 with respect to the cover receiving portion 3 at a rotation angle of about 45 degrees (FIG. 2B). In this intermediate posture, the wiring cover 2 is in a half-open state in which the cutout portion TK and the wiring space DS communicating with the cutout portion TK are half open toward the use edge T1a side of the top plate element T1, and the center of gravity is set in the step portion 54D. Is in a balanced state by engaging the step 54D with the recess 33a. In this manner, the wiring cover 2 is temporarily stopped in a predetermined rotating posture between the lying posture and the standing posture by the step portion 54D and the concave portion 33a. In order to set the wiring cover 2 in the intermediate position to the upright position, the wiring cover 2 is further used as the counter edge of the top plate element T1 with the second convex portion 33c formed on the first standing piece 33 of the cover receiving portion 3 as a fulcrum. Turn to the T1b side. With this turning operation, the second hanging piece 54 of the wiring cover 2 is transferred to the second convex portion 33c, and the wiring cover 2 is in a standing posture in which it stands up at an angle of approximately 90 degrees with respect to the base portion 31 (see FIG.

As a result, the cutout portion TK and the wiring space DS communicating with the cutout portion TK are opened to the use edge T1a side of the top plate element T1 and upward. The wiring cover 2 positioned at the end position of turning to the standing posture can be returned to the intermediate posture or the lying posture by applying an operation force that falls to the use edge T1a side of the top plate element T1. That is, since the center of gravity is set in the vicinity of the stepped portion 54D, in the intermediate posture, the seesaw operation is performed in which the wiring cover 2 can rotate in either the lying posture or the standing posture. In that case, the 1st standing piece 33 functions as a rotation support piece which becomes a fulcrum of the rotation operation between the lying posture and the intermediate posture or the standing posture of the wiring cover 2. On the other hand, the wiring cover 2 in the standing posture can be slid horizontally in a direction approaching the top plate element T1 (top plate T), and the upper plate portion 41 of the cover body 4 is the first upright of the cover receiving portion 3. While being in contact with the piece 33, the upper and lower ends of the first upright piece 33 are sandwiched between the second hanging piece 54 of the backing member 5 and the hanging piece 42 of the cover body 4, and more than that of the wiring cover 2. The rotational movement is restricted ((d) in the figure). In addition, the wiring cover 2 is in a state of being placed on the cover receiving portion 3 in any rotation posture, and is set to be removable from the cover receiving portion 3 by moving the wiring cover 2 in a predetermined direction. Specifically, the wiring cover 2 taking the lying posture can be removed from the cover receiving portion 3 by moving it upward, and the wiring cover 2 taking the standing posture is separated from the top plate element T1 (top plate T). The cover can be removed from the cover receiving portion 3 by sliding it horizontally in the direction of movement. Further, the wiring cover 2 taking the intermediate posture can be detached from the cover receiving portion 3 by moving obliquely upward along the normal direction with respect to the upper surface of the upper plate portion 41 of the cover body 4. In addition, as shown in FIG. 2, when the wiring cover 2 is accommodated in the wiring insertion path S before and after, the operation and the operation method of each wiring cover 2 are the same.
