A table 100, which is an example of furniture with a top plate, includes a top plate 101 having a rectangular shape in plan view, and four leg columns 102 that support portions near the four corners of the top plate 101 from below. In the following description, in FIG. 1, the lower side of the page is referred to as the front or the front, and the upper side of the page is referred to as the back or the back.

The upper ends of the leg struts 102 adjacent on the near side or the far side of the top plate 101 are connected by a horizontal beam 103 that is long in the left-right direction. These horizontal beams 103 are in contact with the lower surface of the top plate 101 and also have a role of supporting the top plate 101 from below. The upper and lower middle portions of the leg struts 102 adjacent on the left or right side of the top plate 101 are connected by a pair of front and rear side beams 104. Then, a connecting portion between one side beams 104 and the other side beam 10.
The four connecting portions are connected by a center beam 105 that is long in the left-right direction. Therefore, the side beams 104, and one center beam 105 of the four leg support post 102,2 present horizontal beams 103,2 pair (4), the framework for supporting the top plate 101 stably is configured Yes.

At the center of the lower surface of the top plate 101, a plate-shaped wiring receiving plate 106 that is long on the left and right is a top plate 10.
It is suspended and fixed with an appropriate space from the lower surface of 1. A wiring opening 107 having a rectangular shape in plan view (long rectangular shape in the embodiment in the left and right directions) is formed above and below the wiring receiving plate 106 in the central portion of the top plate 101 so as to penetrate vertically. The wiring cover device 1 according to the first embodiment is attached to the wiring opening 107. Accordingly, various codes (not shown) are drawn out from below the top plate 101 onto the top plate 101 via the wiring opening 107 (wiring cover device 1).

(2). Schematic Structure of Wiring Cover Device Next, the schematic structure of the wiring cover device 1 will be described with reference to FIGS. In FIG. 4, the rear cover 3 and its guide support means 4 are not shown, and in FIG. 5, the end cover 14 described later is omitted.

Wiring cover device 1 of the first embodiment, rectangular in plan view of the frame body 2 which is open vertically, and a pair of lid 3 before and after covering openably the opening of the frame 2, these frame The body 2 and the lid 3 are long in the left-right direction and short in the front-rear direction. Both the lids 3 can be opened and rotated in a double-spread manner around the longitudinal axis of the laterally long side through the guide support means 4 (details will be described later) (therefore, the “front-rear direction” described above is the lid). It is in a direction perpendicular to the rotational axis of the body 3. ) And can be accommodated in the frame body 2 in the opened state (see FIG. 5 (b)). In this case, both the front and rear lid bodies 3 and the guide support means 4 are incorporated in the frame body 2, and the wiring cover device 1 is unitized as a single unit. Thus, when the wiring cover apparatus 1 is unitized, the assembly work to the top plate 101 can be performed efficiently. In addition, the labor for managing the members can be reduced.

The front and rear lid bodies 3 are arranged in parallel so as to be appropriately spaced forward and backward in the closed state (see FIGS. 1, 3 and 5A). For this reason, the horizontally long wiring gap 5 is vacant between the front and rear lid bodies 3 in the closed state. As shown in FIGS. 3 and 5, when the lid is closed, each lid 3 and the upper opening edge 6 of the opening of the frame 2 (which is also the wiring opening 107) partially overlap in plan view. It is configured. That is, in the closed state, the front end portion (longitudinal end portion) of the front lid body 3 covers the front edge portion 6a (longitudinal one side edge portion) of the upper opening edge 6 of the frame body 2 from above, while the rear The rear end portion (longitudinal end portion) of the lid body 3 covers the rear side edge portion 6b (longitudinal one side edge portion) of the upper opening edge 6 in the frame body 2 from above.

The left and right internal dimensions of the frame body 2 are slightly larger (longer) than the left and right width dimensions of each lid body 3 so that each lid body 3 can be accommodated in the opened state. Further, the front and rear width of the frame 2 in the longitudinal one side edge portion 6a of the upper opening edge 6 of the longitudinal end portions of the cover 3 in the closed state definitive to the frame 2
, 6b is smaller (shorter) than the sum of the front-rear width dimension of the front and rear lid bodies 3 and the front-rear width dimension of the wiring gap 5.

When such a configuration is adopted, the opening of the frame body 2 and the upper opening edge 6 of the wiring opening 107 are connected to each lid 3.
In this case, it is partly hidden (cannot be seen from the outside), so that the opening of the frame 2 and the upper opening edge 6 of the wiring opening 107 are exposed on the top plate 101 (a plurality of long linear shapes as in the prior art). pattern)
Less. Accordingly, the overall combination of the top board 101 and the wiring cover device 1 is reduced in design, and the appearance (appearance) is improved.

The frame 2 is made of a synthetic resin left and right side plate 11 and a front plate 12 and a rear plate 13 formed by extrusion molding of light metal such as aluminum or roll die molding with screws so as to be orthogonal to each other. Concatenated. An end cover body 14 for detaching the relay pivot body 22 and the interlocking pivot rod 27 (details will be described later) is detachably attached to the outer surface side of the left right plate 11. On the upper edge portion of the end cover body 14, a projecting plate portion 15 projecting leftward and rightward is integrally formed. For this reason, when the frame body 2 with the end cover bodies 14 mounted on the left and right sides is fitted into the wiring openings 107 of the top plate 101 from above, the left and right side edge portions of the upper opening edge of the wiring openings 107 are end cover bodies. It is hidden by the 14 overhanging plate portions 15.

On the outer surface side of the front plate 12 and the rear plate 13, a vertical portion of a fixing bracket 16 formed in an L shape is fastened with screws. The frame body 2 with the end cover bodies 14 mounted on the left and right sides is attached to the top plate 10.
The frame 2 is attached to the wiring opening 107 of the top plate 101 by screwing the horizontal portion of the fixing bracket 16 onto the lower surface of the top plate 101 from below while being fitted into the one wiring opening 107 from above. Removably mounted.

A female engagement portion 17 that can be engaged with and disengaged from a male engagement portion 18 provided at a corner portion on the front and rear center side of each lid 3 is provided on the upper inner surface of the left right plate 11 (first embodiment). 2 in the form). Both engagement parts 17 and 18 are configured in a push-latch type that repeatedly engages and disengages by repeatedly pushing and operating the front and rear center sides (particularly the corner part) of each lid 3, and the lid is closed. Then, the front and rear lid bodies 3 are held so as not to be displaced by the engagement of the engaging portions 17 and 18. In addition, a stopper piece 19 is provided at the lower part of the inner surface of the left and right side plates 11 so as to contact the respective lid bodies 3 in the opened state and restrict further accommodation rotation (sinking rotation) (first).
2 in the embodiment).

(3) Detailed structure of guide support means Next, the detailed structure of the guide support means 4 will be described with reference to FIGS.

The guide support means 4 of the first embodiment is provided symmetrically with respect to the left and right of each lid 3 (a pair of left and right) and has the same configuration regardless of the attachment location. Therefore, the front lid 3
The guide support means 4 located on the left side will be described below as a representative example.

The guide support means 4 accommodates the front lid body 3 in the frame body 2 while opening and rotating the front lid body 3 from the closed state (see FIGS. 3 and 5 (a)) (see FIG. 5 (b)). is intended to support so as to shift, the rotating arm punch 21 which supports the front left side of the cover 3 to be vertically pivoted in, the turning arm pestle 2
1 is provided with a relay pivot body 22 that functions as a front end pivot shaft portion and a guide slot 23 as a guide member formed in the left side plate 11.

As shown in FIGS. 4 to 6, the guide slot 23 is formed in the front-rear direction of the left side plate 11 (wiring opening 10.
7 in a direction extending obliquely upward. The guide slot 23 of the first embodiment has an arcuate shape that is obliquely upward toward the front-rear central portion of the left side plate 11. For this reason, the left-side plate 11 of the first embodiment is formed with a pair of front and rear guide slots 23 arranged in a letter C shape.

The base end portion of the rotating arm rod 21 is attached to the left side of the lower surface of the front lid 3. A male fitting portion 24 that is detachably fitted to a female fitting portion 25 that is integrally formed with the relay pivot body 22 is formed at the distal end portion of the rotating arm balance 21. The female fitting portion 25 of the relay pivot body 22 is formed in an outer shape that fits tightly in the groove width of the guide groove hole 23 in a state of being fitted to the male fitting portion 24 of the rotating arm rod 21. .

In this case, the female fitting portion 25 of the relay pivot body 22 is inserted into the guide slot 23 from the outside with the left side plate 11 in between, and the male fitting portion 25 in this state is inserted into the male fitting portion 25 in this state. Mold fitting part 24
Are fitted from the inside with the left side plate 11 in between. For this reason, the relay pivot body 22 and the rotating arm rod 21 are slidable along the guide slot 23 with each other, and the female fitting portion 25.
It can be rotated integrally around it (they are in a fixed relationship).

As shown in FIGS. 5 and 6, when the cover is closed, the relay pivot body 22 is connected to the guide slot 23.
The relay pivot body 22 is set so as to shift to the upper end side of the guide slot 23 as the front lid body 3 opens and rotates. For this reason, when the front lid body 3 in the closed state is pulled up by hand and is opened and rotated around the relay pivot body 22, the relay pivot body 22, and by extension, the front lid body 3 as a whole is lifted up and down the frame body 2. It will move to the center side, and the front end portion of the front lid 3 is separated from the front edge portion 6a of the upper opening edge 6 in the opening of the frame body 2. As a result, the front lid 3 is
It is accommodated in the frame body 2 by turning around the relay pivot body 22 (opened state).

That is, by the sliding action and the turning action along the guide slot 23 in the relay pivot body 22, the front end of the front lid 3 is the front edge of the upper opening edge 6 in the opening of the frame body 2 in the closed state. Despite covering the portion 6a from above, the front lid 3 can be smoothly opened and rotated while avoiding the interference of its front end, and can be accommodated in the frame 2 in the opened state. It has become. As a result, the front lid 3 can be opened and closed smoothly.

On the other hand, in the guide support means 4 of the first embodiment, when the relay pivot body 22 moves to the upper end side of the guide slot 23, the front lid body 3 has the front plate 12 (longitudinal length 1) in the frame body 2 in a side view. An interlocking turning rod 27 is also provided as a restricting member for restricting the turning direction of the front lid 3 so as to fall toward the side wall.

In this case, on the end surface of the relay pivot body 22 on the side opposite to the female fitting portion 25, a recessed hole 26 having an outward opening is formed at a position eccentric from the axis A of the female fitting portion 25. (See FIG. 7), a protruding piece portion 28 protruding from the distal end portion of the interlocking rotating rod 27 is fitted into the recessed hole 26 so as to be rotatable. The base end portion of the interlocking rotary balance 27 is pivotally attached to a pivot shaft 29 that protrudes outward from the outer surface of the left side plate 11.

As shown in FIGS. 5 and 6, when the relay pivot body 22 slides along the guide slot 23, the interlocking rotary rod 27 is inclined obliquely upward and backward from the obliquely upwardly inclined position. In the range up to this, it is configured to be rotatable around the axis of the pivot shaft 29. In this case, the rotation center B, which is a connecting portion between the recess hole 26 of the relay pivot body 22 and the protruding piece portion 28 of the interlocking rotation rod 27, draws a movement locus BL indicated by a one-dot chain line in FIG. .

In the state of FIG. 6, the axis of the pivot shaft 29 is positioned to the left of the center of the radius of curvature of the guide slot 23.
For this reason, the movement trajectory BL of the rotation center B is defined as the movement trajectory AL (see the two-dot chain line in FIG. 6) drawn by the axis A of the relay pivot body 22 (female fitting portion 25) and the side surface. It is a relationship that intersects visually.
In the closed state, when the pivot center B is located in front of the axis A of the relay pivot body 22 and the relay pivot body 22 reaches the upper end of the guide slot 23, the relay pivot body 2
In the state where the shaft center A, the rotation center B, and the pivot shaft 29 are arranged in a straight line when viewed from the side, and the lid is opened (the interlocking rotation scale 27 is most inclined obliquely upward and backward), the relay pivot body 22 is set so as to return slightly from the upper end of the guide slot 23.

Therefore, when the front lid body 3 in the closed state is pulled up by hand and is opened and rotated around the relay pivot body 22, the relay pivot body 22 is positioned on the upper end side of the guide slot 23 as shown in FIG. 6 is rotated counterclockwise (see the direction of the arrow OP) in FIG. As a result, the front lid 3 falls close to the front plate 12 (the lower end side of the guide slot 23) in the frame 2 in a side view, and does not rotate toward the rear plate 13 (rear lid 3). Therefore, the frame body 2 can be surely mounted on the front lid body 3 that opens and rotates without riding on the rear lid body 3 or the top plate 101 in the back.
The opening operation of the front lid 3 can be accommodated more smoothly.
That is, since the interlocking pivot rod 27 and the relay pivot body 22 are pivotally attached to each other, when the relay pivot member 22 is pulled up along the guide groove 23, the interlocking pivot rod 27 is also the axis of the pivot shaft 29. The interlocking rotation rod 27 is pivotally attached to the relay pivot body 22 at a position eccentric to the left from the rotation axis A in the state shown in FIG. The moving center A is pulled up along the guide slot 23 so as to be further away from the pivot shaft 29, whereas the rotation center B moves while drawing a locus BL of an arc around the axis of the pivot shaft 29. Therefore, the relay pivot body 22 is rotated counterclockwise in order to be further lifted along the guide groove hole 23 from the state where the front lid body 3 is pulled up on the frame body 2. The posture must be changed and therefore the relay pivot body 22 As the guide lid hole 23 is pulled up, the front lid body 3 is once pulled up on the frame body 2 and then guided so as to enter the inside of the frame body 2 by changing its posture. (In the state of FIG. 6, the front lid 3 cannot be rotated clockwise while pulling up, but the counterclockwise rotation is smoothly guided.)

The interlocking rotation rod 27 also follows the sliding movement of the relay pivot body 22 and rotates in the clockwise direction (arrow CW direction) around the axis of the pivot shaft 29 in FIG. Then, as shown in FIG. 6B, after the relay pivot body 22 reaches the upper end of the guide slot 23, when the interlocking rotary scale 27 is rotated to the most inclined state in the rearward and upward direction, the relay pivot body 22 is rotated. Body 22 is counterclockwise in FIG.
As a result of further rotating in the turning direction (see the arrow OP direction) and returning slightly from the upper end of the guide slot 23, the front lid body 3 is accommodated and rotated (down-rotating) until it comes into contact with the stopper piece 19. ,
It is accommodated in the frame body 2 and is in an open state.

At this time, the relay pivot body 22 moves back slightly from the upper end of the guide slot 23 (moves to the front side), and the front lid body 3 comes close to the front plate 12 of the frame body 2 so that the lid is opened. It is possible to ensure the widest possible opening width of the opening of the frame body 2 in the open state. For this reason, the wiring work of various cords becomes easy.

When the front lid body 3 in the open state is lifted by hand and is closed and rotated to shift to the closed state, the operations of the front lid body 3, the relay pivot body 22, and the interlocking pivot rod 27 are as described above. because only becomes opposite to, and detailed description thereof will be omitted.

As shown in FIGS. 5 and 7, the interlocking pivot rod 27 of the first embodiment is engaged (fitted) with a protrusion 30 formed on the outer peripheral portion of the relay pivot body 22 when the lid is opened. A click receiving arm 31 is integrally formed. Therefore, by moving the front cover 3 to the open lid state, engages the click receiving arms 31 of the projection 30 is interlocked Kaidokine 27 of the relay pivot member 22, travels a click feeling it clicks to the user . That is, the fact that the front lid 3 has moved to the open state can be transmitted to the user in response.

In the interlocking rotary balance 27 of the first embodiment, the pair of click receiving arms 31 are formed symmetrically on both sides with the main body portion interposed therebetween. Costs and man-hours required for manufacturing the interlocking rotating rod 27 are omitted, and one type of interlocking rotating rod 27 can cope with it.

In the first embodiment, the leaf spring 32 as an urging member that compensates the guide support means 4 with a moving force at the initial stage of the opening / closing movement of the front lid 3 and applies resistance to the guide support means 4 at the end of the opening / closing movement. (See FIG. 7).

In this case, the groove-shaped receiving portion 3 is formed on the end surface of the relay pivot body 22 opposite to the female fitting portion 25.
On the other hand, an accommodation groove 34 is formed on the end face of the interlocking turning rod 27 on the protruding piece 28 side. A leaf spring 32 is incorporated so as to straddle the groove-shaped receiving portion 33 of the relay pivot body 22 and the storage groove portion 34 of the interlocking rotation rod 27.

When the relay pivot body 22 is in the closed state where the relay pivot body 22 is positioned on the lower end side of the guide slot 23, the leaf spring 32 hits the front inner wall of the groove-shaped receiving portion 33 and the storage groove portion 34 (projecting piece portion 28) and faces forward. When the relay pivot body 22 is in an open state where the relay pivot body 22 is positioned on the upper end side of the guide slot 23, the rear inner side wall of the groove-shaped receiving portion 33 is stored. Groove 34 (protruding piece 28
) To bend in the shape of a reverse convex reverse letter (see FIG. 7A).

When the front lid body 3 in the closed state is lifted up by hand and rotated (the initial stage of the opening movement), the leaf spring 3
The elastic restoring force of 2 acts to push the relay pivot body 22 in the counterclockwise direction (see the arrow OP direction) in FIG. For this reason, the relay pivot body 22 rotates counterclockwise in FIG. 7A by the interaction between the interlocking rotary balance 27 and the leaf spring 32 while slidingly moving toward the upper end side of the guide slot 23. Thus, the user can smoothly perform the initial opening operation of the front lid 3 with a relatively light force.

When the front lid 3 is accommodated and rotated (falling down) until it comes into contact with the stopper piece 19 (the end of the opening movement), the relay pivot body 22 resists the elasticity of the leaf spring 32 as shown in FIG. ) In the counterclockwise direction (see the direction of the arrow OP), the rotation direction of the relay pivot body 22 and the leaf spring 3
The direction of the elastic restoring force of 2 is opposite, and a resistance called the elastic restoring force of the leaf spring 32 is applied to the relay pivot body 22.

For this reason, the resistance by the leaf spring 32 acts in a direction that inhibits the opening movement of the front lid body 3 via the relay pivot body 22, and the downward rotation speed of the front lid body 3 suppresses acceleration due to its own weight. Being late. As a result, the front lid body 3 slowly contacts the stopper piece 19 and is held in the open state. Accordingly, at the final stage of the opening movement, the front lid body 3 can be prevented from suddenly turning and turning, and the occurrence of noise and the risk of damage to the front lid body 3 and the surrounding frame body 2 can be reduced.

In addition, when the front lid body 3 in the open state is lifted by hand and moved to the closed state while being rotated, the direction of the elastic restoring force of the leaf spring 32 is merely opposite to the above-described mode. the detailed description thereof will be omitted.

(4) Other Embodiments FIG. 8 and FIG. 9 show another example of the guide support means 4 in the wiring cover device 1. Here, in the second and subsequent embodiments, the same reference numerals are given to the same configurations and operations as those in the first embodiment, and detailed description thereof is omitted. 8 and 9, the end cover body 1

A guide rod 35 is provided to complement the sliding movement along.

The distal end portion of the guide rod 35 in the second embodiment is rotatably connected to the relay pivot body 22, and the center of rotation is connected to the axis A of the relay pivot body 22 (connected and fixed to the rotary arm rod 21). It is made to correspond to the axial center A) of the part. A base end portion of the guide rod 35 is pivotally attached to a pivot shaft 36 that protrudes outward from a portion corresponding to the radius center of the guide slot 23 on the outer surface of the left side plate 11. Accordingly, although not shown in detail, the movement locus of the rotation center of the distal end portion of the guide rod 35 coincides with the movement locus drawn by the axis A of the relay pivot body 22. The main body portion of the interlocking rotation rod 27 and the main body portion of the guide rod 35 are arranged so as to be shifted to the left and right, and the both 27 and 35 do not interfere with each other during the rotation movement.

In 2nd Embodiment, the attachment aspect of a biasing member differs from 1st Embodiment. In this case, an L-shaped leaf spring 37 capable of contacting the front relay pivot body 22 is provided at a front portion of the outer surface of the left and right side plates 11. A U-shaped leaf spring 38 capable of contacting the guide rod 35 is provided. An L-shaped leaf spring 39 that can contact the relay relay body 22 on the rear side is provided at a rear portion of the outer surface of the left and right side plates 11.

The L-shaped leaf springs 37 and 39 and the U-shaped leaf spring 38 share their roles. Each L-shaped leaf spring 37, 39 compensates the relay pivot body 22 with a moving force at the initial stage of the opening movement of each lid 3 by its elastic restoring force, and resists the relay pivot body 22 at the end of the closing movement. It is set to grant. The front portion of the U-shaped leaf spring 38 compensates for the moving force to the guide rod 35 at the initial stage of the closing movement of the front lid 3 by its elastic restoring force, and imparts resistance to the guide rod 35 at the end of the opening movement. Is set to The rear portion of the U-shaped plate spring 38 compensates the guide rod 35 for the moving force in the initial stage of the closing movement of the rear lid 3 by the elastic restoring force, and resists the guide rod 35 in the final stage of the opening movement. Is set to be granted.

Even in such a configuration, as in the first embodiment, the initial opening operation of each lid body 3 can be performed smoothly with a relatively light force, and each lid body 3 suddenly falls down at the end of the opening movement. The movement can be prevented, and the occurrence of noise and the risk of damage to the front lid 3 and the surrounding frame 2 can be reduced.

The guide support means 4 of 3rd Embodiment shown in FIG. 9 is the structure similar to the thing of 2nd Embodiment fundamentally only in the absence of the leaf springs 37-39 group. However, gear members 40 that mesh with each other are provided at the base ends of the front and rear guide rods 35. If the gear members 40 are engaged with each other in this way, it is possible to automatically open and close to the other lid body 3 in conjunction with the opening and closing operation of one lid body 3, and open and close the pair of front and rear lid bodies 3. Operability is improved.

Note that the above-described interlocking mechanism can also be adopted for the guide support means 4 of the first embodiment. In this case, for example, a large-diameter gear member may be provided or a plurality of gear members may be combined in accordance with the distance between the proximal ends of the front and rear interlocking rotary balance 27.
