In addition, when wiring is not performed through a cord extraction hole such as a table top plate or a cord extraction notch, the design of the design is improved by closing the lid of the wiring cover device, resulting in a clean appearance and a flatter impression. Can be improved. In the following, while sitting on a chair and facing the desk, the front side is the front, the opposite side is the rear, the left side is the left, and the right side is the right.

Embodiment 1 FIG.
1-3 is explanatory drawing of the wiring cover apparatus in the desk top board etc. which concern on Embodiment 1 of this invention, FIG. 1 is the desk equipped with the wiring cover apparatus which concerns on Embodiment 1 of this invention. FIG. 2 is an exploded perspective view of the wiring cover device according to Embodiment 1 of the present invention, and FIG.

  In FIG. 1, the desk 1 is composed of support legs 4, 4 and a top plate 2 supported by the support legs 4, 4. The left and right sides of the back of the top board 2 are horizontally long along the left-right direction of the top board 2. Opened cord extraction holes 5 and 5 are formed, and wiring cover devices 7 and 7 are attached to the code extraction holes 5 and 5. Thus, the desk 1 has a clean appearance in which the cord extraction holes 5 and 5 of the top plate 2 are covered with the wiring cover devices 7 and 7, and the design is improved. Then, a wiring duct or the like (not shown) is provided in the space below the top plate 2 to provide a wiring space. From the wiring space or the rear surface side of the desk 1, through the cord extraction holes 5 and 5, The cords are taken out on the top plate 2 and can be wired to an OA device (not shown) used on the top plate 2.

  As shown in FIG. 2, for example, the frame body 8 manufactured by injection molding of a resin such as ABS, polyacetal, polypropylene, or polyethylene terephthalate has a shape that penetrates vertically and can be fitted in the cord extraction hole 5. At the upper end portion, there are provided projecting pieces 8a projecting from front to back and from side to side. Accordingly, the frame body 8 is fitted into the cord extraction hole 5 from the upper side of the top plate 2, the lower surface of the overhanging piece 8 a is brought into contact with the upper surface of the top plate 2, and the top plate faces the cord extraction hole 5. The frame body 8 can be easily fixed to the top plate 2 by engaging the claws 18 provided before and after the frame body 8 with the step portions 5a formed in the lower part.

  Since the outlet box 101 provided with the power plug insertion port 102 and the telephone line plug insertion port 103 is provided with mounting pieces 104 and 104 projecting left and right, the mounting pieces 104 and 104 are framed. If it is placed on the eight placing portions 105, 105, the outlet box 101 can be easily held in the frame 8. In this state, the outlet box 101 is fixed to the frame body 8 by fastening the mounting pieces 104, 104 and the mounting portions 105, 105 with bolts or self-tapping screws. By using such an outlet box 101, it is possible to easily supply power to an OA device and a telephone set used on a desk, connect a telephone line, and the like. Since the outlet box 101 can be attached and detached, when the outlet box 101 is not used, the cords are placed on the top plate 2 from the wiring space below the top plate 2 through the cord extraction holes 5 and 5 as described above. And can be wired to an OA device or the like used on the top board 2.

  As shown in FIGS. 2 and 3, the pivot body 21 includes an outer pivot body 22 and an inner pivot body 23 that are manufactured by injection molding of a resin such as ABS, polyacetal, polypropylene, or polyethylene terephthalate. The support shaft portion 24 of the outer pivot body 22 is fitted from the outside of the frame body 8 into the bearing holes 16 and 16 formed in the opposing side walls 14 and 14 of the frame body 8. And the front-end | tip part of this spindle 24 protrudes from the inner surface 14a of the side wall 14, and the nail | claw 24c, 24c of this front-end | tip part latches on the inner surface 14a of the side wall 14. Therefore, the outer pivot body 22 is rotatably held around the bearing hole 16 of the frame body 8. As described above, the claws 24c and 24c protrude outwardly from the support shaft portion 24 of the outer pivot body 22, and the support shaft portion 24 is provided with holes and slits 24a and 24a. Therefore, the support shaft portion 24 can be elastically deformed to be easily fitted into the bearing hole 16.

  The shaft portion 27 of the inner pivot body 23 is fitted into the outer pivot body 22 fitted to the side wall 14 of the frame body 8 from the hole of the support shaft portion 24 of the outer pivot body 22. Then, the claws 27 c and 27 c at the tip of the shaft portion 27 are engaged with the step portions 24 d and 24 d of the support shaft portion 24 of the outer pivot body 22. Thus, the claw 27c, 27c protrudes outwardly from the shaft portion 27 of the inner pivot body 23. The shaft portion 27 has a hole and slits 27a, 27a. Therefore, the shaft portion 27 can be elastically deformed to easily fit into the hole of the support shaft portion 24 of the outer pivot body 22.

  Further, as described above, the claws 27c, 27c of the shaft portion 27 of the inner pivot body 23 are engaged with the step portions 24d, 24d of the support shaft portion 24 of the outer pivot body 22, and the root of the shaft portion 27 of the inner pivot body 23 is engaged. Since the convex portions 27b formed on the side engage with the slits 24a and 24a and the concave portions 24b and 24b of the support shaft portion 24 of the outer pivot body 22, the outer pivot body 22 and the inner pivot body 23 are firmly Integrate. Therefore, the flange portion 25 projecting from the support shaft portion 24 of the outer pivot body 22 and the flange portion 28 projecting from the shaft portion 27 of the inner pivot body 23 abut against the outer surface 14b and the inner surface 14a of the side wall 14 of the frame body 8, respectively. In this state (the contact surfaces 25a and 28a), the pivot body 21 can be stably rotated around the bearing hole 16 of the frame body 8.

  As shown in FIG. 2, the lid 10 covers the upper opening of the frame 8 in the closed state, and is suspended from the lid 12 that is substantially flush with the upper surface 8 b of the frame 8 and the lid 12. Rotation support portions 13 and 13 are provided, and slide support grooves 13 a and 13 a are formed in the rotation support portions 13 and 13. Therefore, the rotation support portions 13 and 13 are fitted on the slide support portions 29 and 29 provided on the inner pivot bodies 23 and 23, and the lid body 10 is connected to the pivot bodies 21 and 21.

  Therefore, the lid body 10 rotates together with the pivot bodies 21 and 21 around the bearing holes 16 and 16 to open and close the upper opening of the frame body 8, and slide support portions 29 and 29 with respect to the pivot bodies 21 and 21. You can slide as a guide. The slide support portion 29 of the inner pivot body 23 supports the rotation support portion 13 of the lid body 10 so as to be slidable downward in an open state where the upper surface of the lid body 10 is substantially orthogonal to the upper surface 8b of the frame body 8. It is provided in the direction to do.

  The open end edge 19 of the lid portion 12 of the lid body 10 is provided with a cord takeout notch 20a and a lid piece 20b that can be attached to and detached from the cord takeout notch 20a by fitting a dovetail groove or the like. Therefore, when the amount of wiring is small, the upper and lower wirings of the top plate 2 of the desk 1 are wired through the cord extraction notch 20a with the lid 10 closed by removing the lid piece 20b. It can be carried out. In addition, when the cords to be wired have a large connector or the like, the lid 10 of the wiring cover 7 is opened and wired through the connector, and the cord is cut out with the lid 10 closed after the wiring is completed. By passing the cords from 20a, the surroundings of the cords have a clean impression, and the design properties can be improved. The removed lid piece 20b is held by a lid piece holding portion 32c (see FIGS. 5 and 6) provided at the front central portion inside the frame body 8, whereby the lid piece 20b is removed. Loss can be prevented.

  As shown in FIG. 3, the flange portion 25 of the outer pivot body 22 is formed with convex portions 26, 26 that protrude toward the outer surface 14 b of the side wall 14 of the frame body 8 by 180 °. And since the slit 25b ... is formed in this flange part 25, this flange part 25 is easy to elastically deform. Therefore, as described above, the contact surface 25a of the flange portion 25 of the outer pivot body 22 contacts the outer surface 14b of the side wall 14 of the frame body 8 in a state where the outer pivot body 22 and the inner pivot body 23 are combined and integrated. From the state where the contact surface 28a of the flange portion 28 of the inner pivot body 23 is in contact with the inner surface 14a of the side wall 14, the portion where the convex portions 26, 26 of the flange portion 25 are formed is the same as the pivot body 21 and the frame. The state is elastically deformed in the direction perpendicular to the sliding surface with the body 8.

  Therefore, in this state, the portions where the convex portions 26, 26 of the flange portion 25 are formed are elastically deformed, and an elastic biasing force in the direction toward the outer surface 14b of the side wall 14 of the frame body 8 acts. The lid body 10 connected to 21 can be held at an arbitrary position in the opening / closing operation of the lid body 10. Accordingly, the lid 10 can be opened and closed smoothly, and thus the operational feeling during the opening and closing operation can be improved. With such a simple configuration, it is possible to configure a rotation suppressing means that suppresses the rotation of the lid body 10 by applying an elastic biasing force, so that cost reduction and high reliability can be achieved. Further, such an elastic urging force can be made constant through the rotation of the pivot body 21 with respect to the frame body 8 (opening and closing of the lid body 10). As will be described later, the convexity of the outer surface 14b of the side wall 14 is increased. If the circumferential groove 17 or the like having an appropriate depth is formed on the sliding surface of the portion 26, the operational feeling can be easily changed, so that the operability and functionality can be improved. Even if the lid body 10 can be held at an arbitrary position of the opening / closing operation in this way, the pivot body 21 is made of resin and is relatively easily deformed. Therefore, the pivot body 21 is easily rotated with respect to the frame body 8. Therefore, the operability is not deteriorated.

  In this way, the elastic biasing force is applied between the pivot body 21 and the frame body 8 by forming a convex portion that protrudes toward the inner surface 14 a of the side wall 14 of the frame body 8 on the flange portion 28 of the inner pivot body 23. Also good. Moreover, you may form a convex part in the side wall 14 side (outer surface 14b or inner surface 14a). Further, the flange portion 25 of the resin outer pivot body 22 is elastically deformed, and an elastic biasing force is applied by the restoring force of the flange portion 25. For example, between the pivot body 21 and the frame body 8, for example, A structure that incorporates a resin or metal disk spring (such as a dish-shaped toothed washer) with a slit, with a relatively small spring constant, or a deformed diaphragm or bellows The elastic biasing force may be applied by a configuration in which a molded product such as an easily shaped resin is incorporated.

  As described above, an elastic biasing force is applied between the pivot body (not limited to the pivot body 21 including the outer pivot body 22 and the inner pivot body 23) and the frame body 8 to rotate the lid body 10. The lid body 10 is opened and closed by providing an elastic body (which may be integrated with the pivot body 21 like the flange portion 25 of the outer pivot body 22) as a rotation restraining means for restraining movement. Since it can be held at any position of the operation and the lid 10 can be opened and closed smoothly, the operational feeling during the opening and closing operation can be improved.

  Further, instead of providing an elastic body, which is a rotation suppressing means for suppressing the rotation of the lid body 10, between the pivot body and the frame body 8, the lid body and the pivot body are, for example, square-shaped. Due to the concave / convex fitting, etc., they are connected relatively movably in the left / right direction, but the pivot body is attached in the frame body direction by an elastic body provided between the lid body and the pivot body. It is good also as a structure which supports. Even with such a configuration, since the rotation of the pivot body with respect to the frame body is suppressed, a rotation suppressing means for suppressing the rotation of the lid body 10 can be configured.

  Furthermore, a configuration in which a damper, which is a rotation restraining means that suppresses rotation by dissipating kinetic energy, such as an oil damper, an air damper, or a friction damper, is adopted between the pivot body 21 and the frame body 8. Also with such a configuration, the lid body 10 can be held at an arbitrary position of the opening / closing operation, and the lid body 10 can be smoothly opened / closed. Can be improved.

  4A and 4B are explanatory views showing the relationship between the convex part of the pivot body and the circumferential groove formed on the outer surface of the side wall of the frame. FIG. 4A is a side view and FIG. 4B is a developed view of the circumferential groove. FIG. 5 and 6 are longitudinal side views of the wiring cover device. FIG. 5A is a closed state in which the lid is closed, FIG. 5B is a state in which the lid is slightly opened, and FIG. ) Shows an open state in which the lid is opened by about 90 °, and FIG. 6B shows a storage state in which the lid is slid downward. In FIG. 4B, the depth of the circumferential groove 17 formed on the outer surface 14 b of the side wall 14 is the depth of the position A, position B, and position E of the convex portion 26 of the pivot body 21 that moves in the circumferential groove 17. L1 is set to be smaller than the depth from position C to position D.

  In the closed state of FIG. 5A, the lid body 10 is opened to the step portions 32a and 32a (see also FIG. 2 and FIG. 5B) formed on the left and right of the front central portion inside the frame body 8. The left and right lower surfaces of the center portion of the end edge 19 (the cord extraction notch 20a) are in contact with each other, and the open end edge 19 of the lid body 10 is formed on the step portions 32b and 32b formed on the front left and right sides inside the frame body 8. The locking pieces 35, 35 formed on the left and right lower surfaces of the first and second lower surfaces are in contact with each other, and the lid 10 is substantially flush with the upper surface 8 b of the frame 8. Further, holes 33 and 33 are formed in the rear wall of the frame body 8 (see also FIG. 2). The holes 33 and 33 allow the frame body 8 and the slide support portions 29 and 29 of the pivot bodies 21 and 21 to be connected to each other. Avoid interference. If the slide support portions 29 and 29 are brought into contact with the upper surfaces of the holes 33 and 33 in the closed state, a stopper function can be provided by the corresponding contact.

  In this closed state, the convex portion 26 of the pivot body 21 is at a position A (see FIG. 4) in the circumferential groove 17. At this position, the depth L1 of the circumferential groove 17 is set to be relatively large. Therefore, the elastic biasing force by the flange portion 25 is relatively small. In this state, the depth of the circumferential groove L1 may be a depth that eliminates the elastic biasing force. From the state in which the convex portion 26 is at the position A in the circumferential groove 17, as shown by an arrow P in FIG. 5A, if the vicinity of the edge opposite to the open end edge 19 of the lid 10 is pushed downward, the convex portion The portion 26 easily moves to the position B beyond the convex portion 51 in the concave groove 17. Therefore, the lid 10 is easily rotated and opened slightly with a small operating force (see FIG. 5B).

  If the lid 10 is further opened by holding the open end edge 19 of the lid 10 in FIG. 5B from the state where the convex 26 is at the position B in the circumferential groove 17, the convex 26 will be in the concave groove 17. The convex portion 52 (the upper surface of the convex portion 52 is flush with the outer surface 14b of the side wall 14, but may be higher than the outer surface 14b or lower than the outer surface 14b). To position C. At this position, the depth L2 of the circumferential groove 17 is set to be relatively small. Therefore, since the elastic biasing force by the flange portion 25 is relatively large, the force for holding the position of the lid 10 is relatively large. In this state, the lid body 10 can be opened with the same operational feeling up to the position D. At the time of the operation, the distance from the center of rotation of the lid body 10 (center of the bearing hole 16) to the open end edge 19 of the lid body 10 serving as the operation portion is relatively large, so that the moment for the rotation is large. The lid 10 can be easily rotated with a relatively small operating force.

  Next, when the lid body 10 is further opened from the state where the convex portion 26 is located at the position D in the circumferential groove 17, the convex portion 26 becomes the convex portion 53 in the concave groove 17 (the upper surface of the convex portion 53 is the outer surface of the side wall 14. 14b but may be higher than the outer surface 14b or lower than the outer surface 14b) to move to the position E (see FIG. 6A). . This state is the open state in which the lid body 10 is most opened (the lid body 10 is opened by about 90 °), and in order to move the lid body 10 in the closing direction from this state, the convex portion 26 of the pivot body 21 is Since an operating force exceeding the convex portion 53 in the concave groove 17 is required, the lid body 10 is stably held in the open state.

  As described above, by applying an elastic biasing force between the pivot body 21 and the frame body 8, the lid body 10 can be easily held at an arbitrary position of the opening / closing operation. Accordingly, the operational feeling can be improved. In addition, the lid body 10 does not hang down even when the table is turned upside down during transportation or layout change, and damage to the lid body 10 can be prevented, thereby improving reliability. it can. Further, a concave portion having an appropriate depth such as the circumferential groove 17 or a convex portion having an appropriate height such as the convex portions 51 to 53 is formed on the sliding surface of the outer surface 14b of the frame body 8 on which the convex portion 26 of the pivot body 21 slides. If the portion is formed, for example, a click feeling can be obtained at a predetermined position, and the operational feeling can be changed and the functionality can be enhanced. Therefore, the added value of the wiring cover device can be increased.

  Next, storage of the lid 10 will be described. In the open state of FIG. 6A, as described above, the slide support portion 29 of the pivot body 21 is in a direction to support the rotation support portion 13 of the lid body 10 so as to be slidable downward.

Further, support shaft portions 40 and 41 are provided on the edge of the end cover portion 12b on the upper cover portion 12a side, and projecting shafts protruding left and right from the support shaft portions 40 and 41 are formed. Therefore, by fitting the protruding shaft of the end lid portion 12b into the hole of the upper lid portion 12a, the end lid portion 12b is pivotally supported by the upper lid portion 12a.

  If the coil portion of the torsion coil spring 12c is externally fitted to the spring support shaft 40a provided on the support shaft 40 and is assembled between the upper lid portion 12a and the end lid portion 12b, the upper lid portion 12a is applied by the biasing force of the torsion coil spring 12c. The lower surface 42 of the open end edge 19 and the upper surface 43 of the end cover part 12b are in contact with each other, and the rear cover 12b is restricted from pivoting backward, and the cover part is substantially L-shaped in side view. (See FIGS. 9 to 11). The spring support shaft 40a may be provided on the support shaft portions 40 and 41, and the two torsion coil springs 12c and 12c may be incorporated. In addition to the torsion coil spring 12c, an elastic body such as a flat plate torsion spring or a torsion bar may be used.

  The lid body 11 having a substantially L-shaped lid portion configured as described above is formed by the elastic body in a direction in which the end lid portion 12b overlaps the upper lid portion 12a, for example, in the closed state of FIG. It can rotate around the support shaft 40 against the urging force. Therefore, the lid 11 can be opened and closed even when the wiring cover devices 7 and 7 are close to or in contact with the top plate 3 of the desk 1 facing each other. Is also easier.

  In the closed state of FIG. 9A, the lower surface of the upper lid 12a abuts on the step portions 15a, 15a of the left and right side walls 15, 15 of the frame 9, and the upper opening of the frame 9 is covered by the upper lid 12a. The upper surface of the upper lid portion 12a and the upper surface 9b of the frame body 9 are substantially flush with each other. Moreover, the edge part opening of the frame 9 is covered by the end cover part 12b, and the rear surface of the end cover part 12b and the edge side vertical surface 9c are substantially flush (refer also to FIG.9 (b)). . Thus, in the closed state, the back view is a flat appearance, and the design is improved.

  The opening / closing operation and the storing operation and the operational feeling of the lid body 11 in the second embodiment are substantially the same as those in the first embodiment, and the open end of the lid body 11 as shown by the arrow P from the closed state in FIG. When the vicinity of the edge opposite to the edge 19 is pushed downward, the lid 11 is rotated and slightly opened (see FIG. 9B). Then, if the lid 11 is further opened by holding the open end edge 19 of the lid 11 in FIG. 9B, the lid 11 as shown in FIG. (The lid 11 is opened by about 90 °). In this way, both the upper opening and the edge opening of the frame body 9 can be opened by one operation of opening the lid body 11 having a substantially L-shaped lid portion when viewed from the side.

  Next, storage of the lid 11 will be described. Similarly to the first embodiment, the lid 11 is slid downward from the opened state in FIG. 10A to the stored state in FIG. 10B and stored below the upper surface 9b of the frame 9. can do. In this stored state, a part (front side) of the upper opening of the frame body 9 is in a half-opened state covered with the end lid portion 12 b of the lid body 11.

  Here, in the storage state of FIG. 10B, the end lid portion 12b of the lid body 11 comes into contact with the step portions 15c and 15c of the left and right side walls 15 and 15 of the frame body 9, and the lid body 11 is moved downward. The movement is restricted, and the end cover 12b and the upper surface 9b of the frame body 9 are substantially flush. Further, locking grooves 36 and 36 are provided in the step portions 15 c and 15 c of the side walls 15 and 15 so that the locking edge 37 a of the end lid portion tip 37 of the end lid portion 12 b of the lid body 11 is engaged. Good.

  When the lid 11 is raised from the half-opened storage state in which the lid 11 of FIG. 10B is dropped without being folded, to the position of FIG. 10A, for example, the end lid 12b (for example, the end lid) It is necessary to pull up by holding the tip 37). Therefore, in order to ensure the rigidity and strength required for the lifting, the end lid portion 12b is provided with a reinforcing rib 44 (see also FIG. 8). The reinforcing ribs 44 can have an appropriate form such as a lattice shape or a cross beam shape.

  As described above, the lid 11 incorporates a torsion coil spring, which is an elastic body, between the separate upper lid portion 12a and the end lid portion 12b, and is substantially L-shaped in a side view in a normal state by the urging force of the elastic body. However, the end cover 12b can be folded so as to overlap the upper cover 12a against the biasing force. Therefore, in the folded state of the lid body 11, the lid body 11 can be slid downward and stored below the upper surface 9 b of the frame body 9 as in FIG. 10 (see FIG. 11). In this stored state, the upper opening of the frame body 9 is fully open.

  Here, in the storage state of FIG. 11, the end lid portion tip 37 of the end lid portion 12 b of the lid body 11 in the folded state is in contact with the step portions 38 provided on the left and right side walls 15, 15 of the frame body 9. The downward movement of the lid body 11 is restricted, and the upper lid portion 12a and the upper surface 9b of the frame body 9 are substantially flush with each other. In addition, since the standing part 38a is provided in the front edge of the step part 38, the movement to the front of the end cover part 12b is controlled. Therefore, for example, in the storage state of FIG. 11, even if a forward force acts on the lower portion of the upper lid portion 12 a of the lid body 11, the lid body 11 does not fall off.

  As described above, since the lid body 11 can be stored so that the upper opening of the frame body 9 is in the half-open state or the fully-open state, the lid body 11 does not interfere with the top plate 3 during wiring. At the same time, the lid 11 is not lost. Further, since the storage state of the lid 11 in the half-open state or the full-open state can be selected according to the wiring amount or the like and the storage state of the lid according to the use form can be easily made, the cord of the top 3 The wiring around the takeout notch 6 can be made a cleaner impression, and the functionality and design can be improved. For example, the half-open state is suitable for inserting a wiring cord or the like. The fully opened state is suitable for insertion of a large connector or plug or the like in a state where the outlet box 101 is attached to the frame body 9.

  In the above description, the case where the upper lid portion 12a and the end lid portion 12b are separated from each other has been described. However, the upper lid portion 12a and the end lid portion 12b may be integrated.
