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.

  FIGS. 1-7 is explanatory drawing of the cover apparatus of the cord extraction notch in the table top board etc. which concern on embodiment of this invention, FIG. 1 is the notch for code extraction concerning embodiment of this invention. FIG. 2 is an exploded perspective view of a cover device for a cord takeout according to an embodiment of the present invention, and FIG. FIG. FIG. 4 is an explanatory view 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. 4 (a) is a side view, and FIG. It is sectional drawing developed and shown. 5 to 7 are longitudinal side views of the cover device for the cord extraction notch in the tabletop or the like according to the embodiment of the present invention. 5 (a) shows a closed state with the lid closed, FIG. 5 (b) shows a state in which the lid is slightly opened, FIG. 6 (a) shows an open state in which the lid is opened about 90 °, and FIG. FIG. 7B shows a storage state in which the lid body is slid downward, and FIG. 7 shows a storage state in which the lid body is folded and slid downward.

  In FIG. 1, the desk 1 is composed of support legs 4, 4 and a top plate 3 supported by the support legs 4, 4. The left and right sides of the rear edge of the top plate 3 extend along the left-right direction of the top plate 3. The cord extraction notches 6 and 6 that are opened horizontally are formed, and cover devices 7 and 7 are attached to the cord extraction notches 6 and 6, respectively. Thus, the desk 1 has a clean appearance in which the cord extraction notches 6 and 6 of the top plate 4 are covered with the cover devices 7 and 7, and the design is improved. A wiring duct or the like (not shown) is provided in the space below the top plate 3 to provide a wiring space. The wiring space or the rear surface side of the desk 1 passes through the cord extraction notches 6 and 6. The cords are taken out on the top plate 3 and can be wired to an OA device (not shown) or the like used on the top plate 3.

  As shown in FIG. 2, for example, a frame 9 manufactured by injection molding of a resin such as ABS, polyacetal, polypropylene or polyethylene terephthalate penetrates in the vertical direction and is open at the end side, and has a notch 6 for taking out the cord. The upper end portion is provided with a protruding piece 9a protruding in the front and left and right directions, and the protruding portion 9d, 9d protruding forward is formed at the lower end portion (FIG. 5). 7) and projecting pieces 9e, 9e projecting in the left-right direction. Accordingly, the lower surface of the overhanging piece 9a of the frame body 9 is brought into contact with the upper surface of the top plate 3, and the overhanging pieces 9d, 9d are engaged with the engaging recesses 6a, 6a at the front lower part of the cord extraction notch 6. If the projecting pieces 9e, 9e are engaged with the engaging recesses 6b, 6b at the left and right lower portions of the cord extraction notch 6, the frame body 9 can be easily fixed to the top plate 3. Since the frame body 9 is made of a resin and is relatively easily deformed, the attachment to the top plate 3 can be easily performed. Here, for example, if the left and right sides of the frame body 9 are fixed to the left and right sides of the notch 6 of the top plate 3 by tackering or the like, the frame body 9 can be more firmly fixed to the top plate 3. Further, the frame body 9 does not necessarily have a shape penetrating vertically. For example, when the vertical dimension is increased, a configuration in which a bottom plate is provided on all or part of the lower surface may be employed. When such a bottom plate is provided, surplus wiring and the like can be stored on the bottom plate.

  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. 9 can be easily held in the frame body 9. In this state, the outlet box 101 is fixed to the frame body 9 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 3 from the wiring space below the top plate 3 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 3.

  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 9 into the bearing holes 16, 16 formed in the opposing side walls 15, 15 of the frame body 9. And the front-end | tip part of this spindle 24 protrudes from the inner surface 15a of the side wall 15, and the nail | claws 24c and 24c of this front-end | tip part latch on the inner surface 15a of the side wall 15. Therefore, the outer pivot body 22 is rotatably held around the bearing hole 16 of the frame body 9. 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 15 of the frame body 9 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. Accordingly, the flange portion 25 protruding from the support shaft portion 24 of the outer pivot body 22 and the flange portion 28 protruding from the shaft portion 27 of the inner pivot body 23 abut against the outer surface 15b and the inner surface 15a of the side wall 15 of the frame body 9, 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 9.

  As shown in FIG. 2, the lid body 11 includes an upper lid portion 12 a that covers the upper opening of the frame body 9 and is substantially flush with the upper surface 9 b of the frame body 9 in the closed state, and an end of the frame body 9. A lid portion that is substantially L-shaped in a side view and includes an end lid portion 12b that covers the edge opening and is substantially flush with the edge side vertical surfaces 9c, 9c of the frame body 9, and a pivot that hangs down from the upper lid portion 12a Support portions 13 and 13 are provided, and slide 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 11 is connected to the pivot bodies 21 and 21.

  Therefore, the lid body 11 rotates around the bearing holes 16 and 16 together with the pivot bodies 21 and 21 to open and close the upper opening and the edge opening of the frame body 9, and slides relative to the pivot bodies 21 and 21. The support portions 29 and 29 can be slid as guides. The slide support portion 29 of the inner pivot body 23 supports the rotation support portion 13 of the lid body 11 so as to be slidable downward in an open state in which the upper surface of the lid body 11 is substantially orthogonal to the upper surface 9b of the frame body 9. It is provided in the direction to do.

  Suspended pieces 39 are formed on the left and right ends of the open end edge 19 of the upper lid portion 12a, and a hole (not shown) is formed on the inner side of the suspended piece. 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 urged by the urging 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. 5-7). 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 as viewed from the side is configured 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. Accordingly, the lid 11 can be opened and closed even when the top plate 3 of the desk 1 is disposed oppositely and the cover devices 7 and 7 are close to or in contact with each other, so that wiring between adjacent desks can be routed. It becomes easy.

  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 15 b of the side wall 15 of the frame body 9 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 15b of the side wall 15 of the frame body 9 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 15a of the side wall 15, the portion where the convex portions 26, 26 of the flange portion 25 are formed It will be in the state elastically deformed to the orthogonal | vertical direction of the sliding surface with the body 9. FIG.

  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 15b of the side wall 15 of the frame body 9 acts. The lid body 11 connected to the lid body 21 can be held at an arbitrary position in the opening / closing operation of the lid body 11. Therefore, the lid 11 can be opened and closed smoothly, so that 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 11 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 rotation of the pivot body 21 with respect to the frame body 9 (opening and closing of the lid body 11). As will be described later, the convexity of the outer surface 15b of the side wall 15 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 11 can be held at an arbitrary position of the opening and closing operation in this way, the pivot body 21 is made of resin and relatively easily deformed, so that the pivot body 21 can be easily rotated with respect to the frame body 9. Therefore, the operability is not deteriorated.

  In this way, the elastic biasing force is applied between the pivot body 21 and the frame body 9 by forming a convex portion protruding on the inner surface 15 a side of the side wall 15 of the frame body 9 on the flange portion 28 of the inner pivot body 23. Also good. Moreover, you may form a convex part in the side wall 15 side (outer surface 15b or inner surface 15a). Further, the flange portion 25 of the outer pivot body 22 made of resin is elastically deformed and an elastic urging force is applied by the restoring force of the flange portion 25. For example, between the pivot body 21 and the frame body 9, 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 9 to rotate the lid body 11. The lid 11 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 the movement. Since it can be held at any position of the operation and the lid 11 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 11, between the pivot body and the frame body 9, 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. Also 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 11 can be configured.

  Furthermore, a configuration in which a damper, which is a rotation restraining means for suppressing 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 9. Also with such a configuration, the lid body 11 can be held at an arbitrary position of the opening / closing operation, and the lid body 11 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 cover device, FIG. 5 (a) is a closed state in which the lid is closed, FIG. 5 (b) is a state in which the lid is slightly opened, and FIG. 6 (a). Is 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 15 b of the side wall 15 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 lower surface of the upper lid portion 12a contacts the step portions 15a and 15a of the left and right side walls 15 and 15 of the frame body 9, and the upper opening of the frame body 9 is covered by the upper lid portion 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 with 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 (see also FIG.5 (b)). . Thus, in the closed state, the back view is a flat appearance, and the design is improved.

  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 located at the position A in the circumferential groove 17, as shown by the arrow P in FIG. 5A, if the vicinity of the edge opposite to the open end edge 19 of the lid 11 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. Accordingly, the lid 11 is easily rotated and opened slightly with a small operating force (see FIG. 5B).

  If, for example, the lid 11 is further opened by holding the open end 19 of the lid 11 in FIG. 5B from the state where the convex 26 is located 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 15b of the side wall 15, but may be higher than the outer surface 15b or lower than the outer surface 15b). Move over to position C. At this position, the depth L2 of the circumferential groove 17 is set to be relatively small. Accordingly, since the elastic biasing force by the flange portion 25 is relatively large, the force for holding the position of the lid 11 is relatively large. In this state, the lid 11 can be opened with the same operational feeling up to the position D. At the time of the operation, since the distance from the center of rotation of the lid 11 (center of the bearing hole 16) to the open end edge 19 of the lid 11 as the operation portion is relatively large, the moment for the rotation The lid 11 can be easily rotated with a relatively small operating force.

  Next, when the cover 11 is further opened from the state in which 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 15. 15b, but may be higher than the outer surface 15b or lower than the outer surface 15b) to move to a position E (see FIG. 6A). . This state is the open state in which the lid body 11 is most opened (the lid body 11 is opened by about 90 °), and in order to move the lid body 11 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 11 is stably held in the open state. 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.

  As described above, by applying an elastic biasing force between the pivot body 21 and the frame body 9, the lid body 11 can be easily held at an arbitrary position of the opening / closing operation. Accordingly, the operational feeling can be improved. In addition, the lid 11 does not hang down even when the table is turned upside down during transportation or layout change, and the lid 11 can be prevented from being damaged, so that the reliability can be improved. it can. Further, a concave portion having an appropriate depth such as the circumferential groove 17 or a convex having an appropriate height such as the convex portions 51 to 53 is formed on the sliding surface of the outer surface 15b of the frame body 9 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 cover device can be increased.

  Next, storage of the lid 11 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 11 so as to be slidable downward. As described above, the lid body 11 can be slid with respect to the pivot bodies 21 and 21 using the slide support portions 29 and 29 as a guide, so that the lid body 11 is lower than the upper surface 9 b of the frame body 9. (See FIG. 6B). Therefore, the lid 11 does not get in the way on the top plate 3 during wiring, and the lid 11 is not lost. 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. 6B, the end lid portion 12 b of the lid body 11 abuts on the step portions 15 c and 15 c 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. Note that the lid 11 is not necessarily housed entirely below the upper surface 9b of the frame body 9, but a part of the lid body 11 is placed below the upper surface 9b of the frame body 9. You may comprise so that it may accommodate.

  When the lid 11 is lifted from the half-opened storage state in which the lid 11 of FIG. 6B is dropped without being folded to the position of FIG. 6A, 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 necessary for the lifting, the end lid portion 12b is provided with a reinforcing rib 44 (see also FIG. 2). 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. 6 (see FIG. 7). In this stored state, the upper opening of the frame body 9 is fully open.

  Here, in the storage state of FIG. 7, 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. 7, even if a forward force acts on the lower portion of the upper lid portion 12a 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.

  As shown in FIGS. 2 and 6, the slide support portion 29 of the pivot body 21 is provided with a pressing piece 30... Having a convex portion 31. ing. In the state where the pressing piece 30... Is in the slide groove 13 a of the rotation support portion 13 of the lid 11 that is fitted on the slide support portion 29, the cantilevered pressing piece 30. Since the elastic biasing force toward the rotation support portion 13 of the lid body 11 works due to elastic deformation, the lid body 11 can be held at an arbitrary position of the storage operation, and the operational feeling during the storage operation can be improved. it can.

  In the configuration of the present embodiment, in the middle of lowering the lid body 11 from the open state of FIG. 6A to the housed state of FIG. 6B, the slide body 13 is inserted into the slide groove 13 a of the rotation support portion 13 of the lid body 11. Since the pressing piece 30 is eliminated, the elastic urging force is not applied to the lid body 11 below this position. However, the elastic urging force can be applied from the open state in FIG. 6A to the retracted state in FIG. 6B by the same configuration as the present embodiment. Accordingly, the lid body 11 can be held at all positions of the lid body 11 in the storing operation.

  Even if the lid 11 can be held at an arbitrary position of the storing operation in this manner, the pivot body 21 (slide support portion 29) is made of resin and is relatively easily deformed, so that the operability is not deteriorated. Moreover, you may form the convex part 31 ... in the slide groove | channel 13a of the rotation support part 13 instead of the press piece 30 ....

  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.
