Description

  The present invention relates to a wiring cover device that can be attached to a top plate and cover a wiring space below the top plate.

In recent years, computer work is often performed on the top board of furniture with a top board such as a desk. In order to drop cords such as communication cords and power cords below the top board, the top board has a wiring space below it. In general, a wire insertion passage communicating with the wire is formed. Conventionally, various wiring cover devices have been considered which are arranged at positions where the wiring space can be covered from above. For example, as an example, a column-like shape in which a wiring insertion passage such as a notch communicating with the wiring space is formed in a part of the top plate and protruded so as to face both side ends of the wiring insertion passage in a horizontal posture. A pin support (hereinafter referred to as a bearing) provided on the rotating end side of the wiring cover is engaged with and attached to a support pin (hereinafter referred to as a support shaft). The thing which comprised the channel | path so that opening and closing was possible is considered (for example, refer patent document 1). In this wiring cover device, when the wiring cover is positioned in a predetermined rotation posture, the engagement state between the support shaft and the bearing can be released to remove the wiring cover, and the wiring insertion path is completely opened. It is also configured to be able to.

  However, in the above, the support shaft is fixed in the wiring insertion path, and the bearing must be provided on the wiring cover as well, which complicates the structure and makes the manufacturing process complicated. There arises a problem of incurring an increase in cost. In addition, since the engagement state between the support shaft and the bearing can be released only when the rotation posture of the wiring cover takes a predetermined posture, the removal work cannot be easily performed. In addition, when it is desired to close the wiring insertion path from the state where the wiring insertion path is fully opened, the wiring cover is positioned in the predetermined rotation posture, and the bearing is held in the state where the rotation posture is maintained. Since the wiring cover is attached by being engaged with each other, the attaching operation is troublesome. As described above, the conventional one cannot easily perform the attaching / detaching operation of the wiring cover, and is not easy to use. In addition, while the mounting / removal operation is repeated, there is a possibility that the support shaft or the bearing is damaged and a good mounting state cannot be maintained. Furthermore, since the support shaft is fixed in the wiring insertion passage, the presence of the support shaft itself becomes an obstacle to wiring work.

  The present invention has been made paying attention to such problems, and a main object of the present invention is to provide a wiring cover device that can easily perform the attaching / detaching operation of the wiring cover by using a simple structure. is there.

  That is, the wiring cover device of the present invention is arranged at a position where the wiring space formed below the top plate in the furniture with the top plate can be covered from above, and can be opened and closed, and the top plate A cover receiving portion that is provided at a portion communicating with the wiring space and supports the wiring cover in a detachable manner, and the wiring cover is placed on the cover receiving portion and supported by its own weight, The wiring cover has an upper surface that is substantially flush with the top surface of the top plate, and a lying posture that can close the wiring space, and its open end protrudes above the top surface of the top plate to open the wiring space. Any of the standing postures to be obtained can be selectively taken.

  In such a case, it is not necessary to provide a support shaft as compared with the conventional one, and a simple structure can be used, which contributes to simplification of the manufacturing process and cost reduction. In addition, since the wiring cover is only placed on the cover receiving portion, the wiring cover can be easily removed regardless of the orientation of the wiring cover, and the wiring cover can also be simply mounted on the cover receiving portion. Just place it. In this way, the wiring cover can be attached and detached very easily, and it is easy to use. In addition, since the wiring cover is supported by its own weight in the lying posture and the standing posture, it is possible to realize a stable mounting state, and the wiring work and the work on the top plate are performed with the simple structure as described above. It will have no practical problems and will be highly practical.

  In order to stably and smoothly rotate between the lying posture and the standing posture while stably supporting the wiring cover, the wiring cover is supported rotatably with respect to the cover receiving portion. It is desirable that the cover receiving portion is provided with a rotation support portion serving as a fulcrum of the rotation operation between the lying posture and the standing posture of the wiring cover.

  If the rotation operation of the wiring cover with respect to the cover receiving portion is accompanied by a seesaw operation, the rotation is performed while maintaining a balance, so that a more stable rotation operation can be realized.

  If the rotation direction of the wiring cover between the lying posture and the standing posture is different from the direction in which the wiring cover is removed from the cover receiving portion, the wiring cover that takes the lying posture is rotated. Thus, the wiring cover can be prevented from falling off when it is placed in the standing posture.

  In order to regulate the rotation operation of the wiring cover taking a standing posture and maintain a good standing posture with a simple operation, the wiring cover located at the rotation end position of the wiring cover to the standing posture is What is necessary is just to comprise so that rotation operation | movement to the said lying posture of a wiring cover may be controlled by slidingly moving in a direction.

  Further, if a wiring insertion passage communicating with the wiring space is formed in the top plate, and the rotation support portion provided in the cover receiving portion is substantially plate-shaped along the peripheral wall of the wiring insertion passage, the wiring It is possible to realize a stable pivoting operation of the cover and prevent the wiring insertion path from being unduly narrowed by the configuration for the operation of the wiring cover.

  In addition, if there is a stationary means that can temporarily stop the wiring cover in a predetermined rotation posture between the lying posture and the standing posture, not only two modes of the lying posture and the standing posture are provided. And since the rotation attitude | position of a wiring cover can be selected in the predetermined position in the meantime, the rotation attitude | position of a wiring cover can be adjusted in steps corresponding to the usage condition of a worker.

  A specific embodiment of the stationary means includes a fixed engagement element having a part of the rotation support portion depressed, and a movable engagement provided on the wiring cover and engageable with the fixed engagement element. Preferably, the wiring cover is configured to be stationary in a predetermined rotation posture by rotating the wiring cover and engaging the movable engagement element with the fixed engagement element. . If it is such, a stationary means can be implement | achieved by a simple structure, and a wiring cover can be made still at a predetermined position by simple operation.

  In order to effectively prevent the wiring cover from falling off even in the standing posture and to realize a good support state, the wiring cover may be placed on the rotating support portion in the standing posture.

  On the other hand, in order to effectively prevent the wiring cover from falling off in a lying posture and realize a good support state, the cover receiving portion is not blocked from the lower edge of the wiring insertion path to the inside. It is preferable that a drop prevention portion that protrudes to prevent the wiring cover from dropping is provided, and the wiring cover is placed on the drop prevention portion in the lying posture.

  In particular, while improving the operability without providing a protrusion on the upper surface side of the wiring cover, even when the wiring cover is in a lying down state, cables such as a wiring cord pass between the upper surface side of the top plate and the wiring insertion path. In order to be able to do so, the wiring cover is provided with an operation part that is partially cut away, and the wiring cover can be rotated using this operation part. What is necessary is just to comprise so that code | cord | chords can be penetrated from an operation part.

  As described above, according to the wiring cover device of the present invention, it is not necessary to provide a support shaft in a portion communicating with the wiring space in the top plate, and a simple structure can be adopted as compared with the conventional one. Contributes to simplification of production process and cost reduction. Further, since the wiring cover is merely placed on the cover receiving portion in the lying posture and the standing posture, the wiring cover can be easily attached and detached in any posture in accordance with the use mode of the worker. . In addition, since the wiring cover is supported by its own weight in the lying posture and the standing posture, a stable wearing state can be realized.

Note that any mounting mode 2 ( P) and 2 (Q) are also set so that the two wiring covers 2 can be accommodated in the substantially square-shaped wiring insertion passage S, and in particular, the notch portions facing each other in the first mounting mode 2 (P). When the wiring covers 2 are respectively accommodated in the TK, the layout is such that seats are arranged on the front edge side and the rear edge side of the top plate T, respectively, so that it is easy to use for workers of each seat.

  Next, an operation method and operation of the wiring cover device 1 adopting the first mounting mode 2 (P) will be described with reference to FIGS.

  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 portion of the present invention. 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 recess 33a provided on the first upright piece 33 of the cover receiving portion 3, and the step A region near the portion 54 abuts on the inclined surface 33d, and the wiring cover 2 is temporarily stopped at a rotation angle of about 45 degrees with respect to the cover receiving portion 3 so that the wiring cover 2 assumes the intermediate posture (same as above). (B). 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. As described above, the step portion 54D and the concave portion 33a constitute the stationary means of the present invention that can temporarily stop the wiring cover 2 in a predetermined rotational posture between the lying posture and the standing posture. 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. (C)). In this standing posture, the wiring cover 2 is placed on the second standing piece 34. 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 part of this invention used as the fulcrum of rotation operation | movement between the lying posture of the wiring cover 2, and an intermediate | middle posture or a standing posture. 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. In addition, since there is a gap TS between the counter-use ends T1b of the top and bottom plate elements T1 that are paired in the front and rear directions, the wiring covers 2 do not interfere with each other even if the respective wiring covers 2 are operated simultaneously. . In other words, the width of the gap TS is set so that the wiring covers 2 do not interfere with each other even if the respective wiring covers 2 are operated simultaneously.

  Moreover, the table X of this embodiment comprises the auxiliary top plate 6 so that attachment or detachment is possible in the position which straddles the outer side edge part of a pair of top plate element T1 which counter-used edge T1b was opposingly arranged. The auxiliary top plate 6 has a thin plate shape having a width dimension substantially corresponding to the front and rear dimensions of the top plate T, and the front edge corresponds to the side edge of the top plate X constituted by the side edges of the top plate element T1. This leading edge can be used as the working edge 6a. 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. In a state where the auxiliary top plate 6 is slid inward from the side of the top plate T and attached to the top plate T, the notch portion 6K of the auxiliary top plate 6 is the notch portion TK of the pair of top plate elements T1. Matches. And the 2nd mounting mode 2 (Q) which can open the wiring insertion path S toward the side edge of the top plate T for the wiring cover 2 is selected, and through the notch 6K of the auxiliary top plate 6, It is accommodated so as to be bridged between the notches TK of the pair of top plate elements T1, and is set so that the wiring insertion path S can be opened toward the side edge of the top plate T, that is, the use edge 6a of the auxiliary top plate 6. Thereby, it is possible to facilitate the operation of the wiring cover 2 and the access to the wiring insertion path S for a worker who uses the use edge 6a side of the auxiliary top plate 6 as a seat. In this mounting mode 2 (Q), the wiring cover 2 is provided between the lying posture and the intermediate posture or the standing posture with the second standing pieces 34 provided on the cover receiving portions 3 and arranged opposite to each other in the front-rear direction as fulcrums. Rotate between them. In this case, the second upright piece 34 plays a role as a rotation support portion. The operation method and operation of the wiring cover device 1 in this mounted state are the same as in the mounting mode 2 (P) in which the wiring cover 2 is rotated with the first upright piece 33 of the cover receiving portion 3 as a fulcrum. I will omit the explanation.

  As described above, the wiring cover device 1 according to the present embodiment includes the wiring cover 2 that can be opened and closed, and the cover receiving portion 3 that is provided in the notch TK formed in the top plate element T1 and supports the wiring cover 2 so as to be removable. With the wiring cover 2 placed on the cover receiving portion 3 and supported by its own weight, the wiring cover 2 can be configured to selectively take at least one of the lying posture and the standing posture. Therefore, it is not necessary to provide a support shaft for rotatably supporting the wiring cover 2, and a simple structure can be used. As a result, it contributes to simplification of the manufacturing process and cost reduction. Moreover, since the wiring cover 2 is merely placed on the cover receiving portion 3, the attaching / detaching operation of the wiring cover 2 can be performed very easily. Further, since the wiring cover 2 is supported by its own weight in the lying posture and the standing posture, a stable mounting state can be realized, and the wiring work and the top plate T (the top plate T) can be realized while having the simple structure as described above. The work on the plate element T1) is not hindered and is highly practical.

  The wiring cover 2 is supported so as to be rotatable with respect to the cover receiving portion 3, and the cover receiving portion 3 is provided with a rotation support that serves as a fulcrum for the rotating operation between the lying posture and the standing posture of the wiring cover 2. Since the first upright piece 33 and the second upright piece 34 functioning as the parts are provided, the rotation operation between the lying posture and the upright posture can be made stable and smooth.

  In particular, since the rotation operation of the wiring cover 2 with respect to the cover receiving portion 3 is accompanied by a seesaw operation, the rotation can be performed while maintaining a balance, and a more stable rotation operation can be realized.

  Further, since the rotation direction between the lying posture and the standing posture of the wiring cover 2 is different from the pulling direction in which the wiring cover 2 is removed from the cover receiving portion 3, the wiring cover 2 that takes the lying posture is provided. It is possible to reliably prevent the wiring cover 2 from being pulled out when it is rotated and positioned in the standing posture.
