  Next, embodiments of the present invention will be described with reference to FIGS. 1 to 4 and 17, FIGS. 5 to 8, FIGS. 9 to 12, and FIGS. 13 to 16.

  First, in FIGS. 1 to 4 and FIG. 17, 1 is a table top 2, 2 is an example of the top plate 1, and the length of the top 1 is approximately at the center in the front-rear width direction of the top 1. A wiring duct having a concave or bowl-shaped cross section attached under the top plate 1 along the top, and an opening 2a at the top of the duct 2 is here an opening 1a (also referred to as an opening 1a) formed in the top plate 1. It is formed in substantially the same width. Some of the wiring ducts 2 are provided closer to the front in the front-rear width direction of the top plate 1, and of course the mounting structure of the present invention can be applied. Further, the present invention can also be applied to a cover of a wiring duct whose opening width of the wiring duct is about ½ of the embodiment described below. However, in this case, a wiring cover described later may be a single sheet type.

  In the opening 2a (also referred to as opening 2a) of the duct 2 formed along the length direction of the top plate 1, wiring covers 3 and 4 to be described later are installed at least at both ends and intermediate portions of the opening 2a. As a member for this purpose, a cover receiving metal fitting 5 having a substantially reverse concave shape in cross section having claws 5a, 5b engaged and supported by wall surfaces 2b on both sides of the opening 2a of the duct 2 is mounted. In addition, in the entire length of the opening 2a of the wiring duct, the mounting span of the cover bracket 5 corresponds to the length of the wiring covers 3 and 4 described later.

  6 is provided with two mounting holes 7 and 8 and 9 and 10 at positions symmetrical to the left and right of the drawing with respect to the center in order to mount support shaft blocks 11 and 12, which will be described later, to the receiving metal 5. It is a block mounting member having a substantially reverse concave cross section. The mounting member 6 is mounted and supported on the metal fitting 5 in a manner straddling the receiving metal fitting 5.

  The support shaft blocks 11 and 12 in the first example (see FIGS. 1 to 4 and 17) and the second example (see FIGS. 5 to 8) of the mounting structure of the present invention have the following configurations. Since the support shaft blocks 11 and 12 are the same member only in the direction of use, the following description will be made on the support shaft block 11. However, in the support shaft block 12, the letters after the numerals that are the same as those in the block 11 are the same as the corresponding members and parts of the support shaft block 11.

  The lower half of the support shaft block 11 has a substantially mouth-like flat cross-section that is closely fitted into all of the four mounting holes 7 to 10 in the original direction or the direction reversed 180 degrees in the plane. It is formed on the base leg 11a. The upper half side of the block 11 has a substantially vertical wall 11b on one side and a shaft 11c on which the bearing portions 3a and 4a of the wiring covers 3 and 4 (to be described later) can be detachably fitted on the other side. . Further, an arcuate guide 11d is arranged between the shaft 11c and the standing wall 11b so as to surround the shaft 11c. Note that the lower surface of the distal end of the guide 11d is formed in a locking portion 11e having a downward convex cross section.

  The support shaft block 12 includes a base leg 12a, an upright wall 12b, a shaft 12c, an arcuate guide 12d, and a locking portion 12e in the same manner as the block 11. Each of the mounting holes 7 to 10 of the block mounting member 6 has a plane shape that is point-symmetric when viewed from the same plane as the base legs 11a and 12a that are point-symmetric when viewed from the flat surface. The symmetry of these members is the same in the following embodiments.

  Next, the wiring covers 3 and 4 will be described. The wiring covers 3 and 4 have the same cross-sectional shape and structure as the support shaft blocks 11 and 12, but the usage is symmetric, so the same manner as the support shaft blocks 11 and 12 is used. One wiring cover 3 will be described.

The wiring cover 3 includes a substantially semicircular bearing 3a fitted on the shaft 11c of the support shaft block 11 on the back surface on the front end side, and has a rubber- or plastic-based flexible wing shape on the rear end side. A mounting portion 3b of the free cover 3A having a laterally concave shape for fixing the free cover 3A is provided.
On the outer peripheral surface of the bearing 3a, concave locked portions 3c that receive the locking portions 11e of the support shaft block 11 are provided at three locations in the example of the figure.
Since the wiring cover 4 is also a member that has the same form as the wiring cover 3 and is used in a symmetric direction, the wiring cover 4 includes a mounting portion 4b and a locked portion 4c for mounting the bearing 4a and the free cover 4A.

  The first example of the wiring cover mounting structure of the present invention described with reference to FIG. 1 having the above-described structure is assembled as shown in FIG. 2 and functions as a cover (lid) that can freely open and close the opening 2a of the wiring duct 2. Therefore, the state where the wiring covers 3 and 4 are opened will be described with reference to FIGS.

  FIG. 3 shows that the wiring covers 3 and 4 are rotated 90 degrees in the clockwise direction and the cover 4 is rotated counterclockwise, respectively. It shows a state in which the opening 2a of the wiring duct 2 (including the opening 1a of the top plate 1; the same applies hereinafter) is opened in an upright (standing) posture.

When the wiring covers 3 and 4 are raised 90 degrees, the convex cross-section engaging portions 11e and 12e formed at the tips of the arcuate guides 11d and 12d are connected to the bearings 3a and 4a in the wiring covers 3 and 4, respectively. It fits into the locked portion 3c on the distal end side of the two concave locked portions 3c formed on the distal end side of the outer peripheral surface of the wiring cover 3 and maintains the upright posture of the wiring covers 3 and 4.
Incidentally, when the wiring covers 3 and 4 are closed, the engaging portions 11e and 12e formed at the tips of the guides 11d and 12d are the outer peripheral end (root side) of the bearing portion 3a of the wiring covers 3 and 4. And the closed state of the wiring covers 3 and 4 is held without rattling.
The upper end portions of the standing walls 11b and 12b of the support shaft blocks 11 and 12 have a role of supporting the closed wiring covers 3 and 4 from the lower surface thereof.

  In the opening mode in which the wiring covers 3 and 4 of FIG. 3 stand upright back to back, the opening in which the cover bracket 5, the block mounting member 6, the support shaft blocks 11 and 12, etc., which are the mounting mechanisms of the wiring covers 3 and 4 are not arranged. In and out of the wiring duct 2 at the part 2a (1a), the wiring operation and connection equipment can be taken in and out, the wiring process, and the like can be performed from both the left and right directions in the figure of the top board 1. If the wiring covers 3 and 4 are tilted 90 degrees from the state shown in FIG. 3 in the opposite direction to the standing (opening) state, the state returns to the state shown in FIG. 2 and the openings 2a and 1a of the wiring duct 2 and the top plate 1 are closed. It will be in the state.

  FIG. 4 shows a state in which when the desktop panel DP is arranged at the center of the wiring duct 2 of the top plate 1, the lower end of the panel DP and the opened wiring covers 3 and 4 stand at an angle that does not interfere with each other. Yes. Although not shown, the desktop panel DP has support legs (not shown in the drawing) at both left and right ends when viewed from the front of the panel DP, and the support legs are attached to the receiving metal 5 or the like as an example. Thus, it is erected on the top board 1.

In FIG. 4, the wiring covers 3 and 4 are each held 70 degrees in the illustrated example, and are held in the standing posture to avoid interference with the lower end side of the desktop panel DP. Locking portions 11e, 12e provided at the tips of the arcuate guides 11d, 12d are formed from the ends of the two concave locked portions 3c, 4c formed on the outer peripheral surface tip side of the bearings 3a, 4a of the wiring covers 3, 4. It is maintained by fitting into the second locked portions 3c and 4c as seen.
Even in the open state of the wiring duct 2 with the wiring covers 3 and 4 standing at 70 degrees, the handling and processing of wiring and the like related to the inside and outside of the duct 2 are almost the same as in the state of FIG.

  In the above description, the shafts 11c and 12c of the support shaft blocks 11 and 12 are opposed (facing), and the blocks 11 and 12 are mounted in the mounting holes 7 and 8 on the inner side (near the center) of the block mounting member 6. In this example, the wiring covers 3 and 4 are attached to the blocks 11 and 12 at the bearings 3a and 4a, respectively.

  In the mounting structure of the present invention, as shown in FIGS. 5 to 8, the support shaft blocks 11 and 12 are inserted into the mounting holes 9 and 10 on the outside of the block mounting member 6 in the plane from the direction of the first embodiment. A posture rotated 180 degrees, that is, the shafts 11c and 12c of the support shaft blocks 11 and 12 are mounted so that they face each other outward (in other words, the standing walls 11b and 12b face each other). In addition, the wiring covers 3 and 4 are mounted in a manner in which the bearings 3a and 4a are supported.

  When the shafts 11c and 12c of the support shaft blocks 11 and 12 are located on the outside, the free covers 3A and 4A of the wiring covers attached to the shafts 11c and 12c face each other, contrary to the examples of FIGS. Positioned in the state. (This means that the support shaft blocks 11 and 12 shown in FIG. 2 and the wiring covers 3 and 4 attached to these blocks 11 and 12 are attached to the mounting holes 7 and 4 with the covers 3 and 4 attached. This is the same as the case where one of the support shaft blocks 12 is mounted in the mounting hole 9 and the other support shaft block 11 is mounted in the mounting hole 10.

  5 to 8, the shafts 11c and 12c of the support shaft blocks 11 and 12 are positioned at positions close to the opening 1a of the top plate 1 and the wiring cover is installed. When the bearings 3a and 4a are attached to the shafts 11c and 12c with the free covers 3A and 4A butting the respective free covers 3A and 4A (see FIG. 6), the closed wiring covers 3 and 4 are 7. As illustrated in FIG. 8, it is opened in a so-called double-open (double-open) state. In the opened state, the 90-degree standing posture and the 70-degree standing posture are the same as those described in the examples of FIGS.

  The mounting structure of the present invention will be described below because there is an example using the support shaft blocks 11 and 12 and the wiring covers 3 and 4 in the modes shown in FIGS. In the example of FIGS. 9 to 16, the structure of the support shaft blocks 11 and 12 and the structure of the wiring covers 3 and 4 supported by the blocks 11 and 12 so as to be openable and closable are different. 9 to 16, the same reference numerals are used for the same members and parts as those in FIGS. 1 to 8.

  The support shaft blocks 11 and 12 of FIGS. 9 to 16 include the base legs 11a and 12a in the lower half of the block that are fitted into the mounting holes 7 to 10 and the standing walls 11b and 12b on the upper half. Although common to the examples of FIGS. 1 to 8 described above, since the forms of the shaft 11c and the locking portion 11e in FIGS. 1 to 8 are different, the support shaft block 11 and the wiring cover 3 will be described below. The other support shaft block 12 and the wiring cover 4 are displayed in such a manner that the alphabet after the numeral coincides with the corresponding portions and parts of the block 11 and the wiring cover 3.

  In the support shaft block 11, a shaft 11g is formed at the upper end of the stepped wall 11f on the opposite side of the standing wall 11b. 11h is a tongue-like projection formed below the shaft 11g, and a projection 11i serving as a locking portion is provided on the upper surface of the projection 11h. In addition, the convex part 11j used as a latching part is provided also in the back surface of the standing wall 11b. In the support shaft block 12, 12f is a stepped wall, 12g is a shaft provided on the wall, 12h is a tongue-like projection, and 12i and 12j are convex portions serving as locking portions.

  On the other hand, the wiring covers 3 and 4 attached to the support shaft blocks 11 and 12 having the above configuration include bearings 3a and 4a corresponding to the configuration of the blocks 11 and 12 and attachment portions 3b and 4b of the free covers 3A and 4A. Although the point is substantially the same as the embodiment of FIGS. 1 to 8, it corresponds to the two convex portions 11i, 11j and 12i, 12j which are locking portions provided on the support shaft blocks 11, 12. The formed locked portions 3d and 3e and 4d and 4e are different from the examples of FIGS.

  That is, at the end of the back surface of the wiring covers 3 and 4 (side closer to the bearings 3a and 4a), the convex portions 11i provided on the tongue-like projections 11h and 12h when the covers 3 and 4 are raised. Wing-like locked portions 3d and 4d that fit into 12i are provided, and locked portions 3e that fit into convex portions 11j and 12j provided on the standing walls 11b and 12b when the covers 3 and 4 are turned down, 4e is provided in the vicinity of the attachment portions 3b and 4b of the free covers 3A and 4A.

  The third example of the mounting structure of the wiring duct cover of the present invention having the above configuration is the same as that of FIG. 2 of the first embodiment in that the wiring cover 3 and 4 are closed and the state shown in FIG. . The support shaft blocks 11 and 12 are mounted in the mounting holes 7 and 8 with the shafts 11g and 12g facing each other, and the wiring covers 3 and 4 are mounted on the shafts 11g and 12g of the blocks 11 and 12, respectively. The cover 3 and 4 are raised 90 degrees back to back to open the opening 2a of the wiring duct 2 (see FIG. 11), and if there is a desktop panel DP, it interferes with it. In order to avoid this, the wiring covers 3 and 4 can be opened only up to 75 degrees (see FIG. 12), as in the case of FIGS. 3 and 4 described above. The 90 degree standing state and 75 degree standing state of the wiring covers 3 and 4 are maintained by fitting the locked portions 3d and 4d to the convex portions 11i and 12i provided on the tongue-like projections 11h and 12h. .

  In the third example of the mounting structure of the present invention described in the third embodiment with reference to FIGS. 9 to 12, the support shaft blocks 11 and 12 are rotated 180 degrees in a plane so that the shafts 11g and 12g face outward (the standing walls 11b, 12b are faced to each other, and the blocks 11 and 12 are fitted into the mounting holes 9 and 10 located outside, and the wiring covers 3 and 4 are attached to the shafts 11g and 12g of both the blocks 11 and 12, respectively. When the covers 3A and 4A are mounted with bearings 3a and 4a in the face-to-face orientation, the two wiring covers 3 and 4 are double-opened (double-open) as in the case of the second embodiment described above with reference to FIGS. Can be mounted in a manner. This mounting structure is the fourth example of the mounting structure of the present invention, and the details thereof are as shown in FIGS.

  The wiring cover mounting structure of the present invention is as described above, and the mounting structure of the first example and the second example is the same as the mounting structure of the third example and the fourth example. Therefore, it is possible to select a double-opening (double door opening) or single-opening (back-to-back opening) manner, so that it is possible to provide a wiring duct cover device that is extremely easy to use.

  In any of the embodiments, the support shaft block attached to the block mounting member and the wiring cover attached to the block both use the same form of the member in a symmetric direction, so the number of parts is small. There is an advantage that different arrangement modes and different opening / closing modes of the wiring cover can be realized. In addition, since the structure for that purpose is very simple, it is convenient that it can be easily assembled and disassembled as well as manufactured.
