When the side end member 14, the rear end member 15, and the flexible member 16 are mounted, the rear ends of the side end member 14, the rear end member 15, and the flexible member 16 are respectively continuous in a substantially linear shape in plan view. The rear edge of the top board 1 is formed. In particular, the flexible member 16 is appropriately deformed to form a dent in the rear edge of the top plate 1, so that cords connected to various devices placed on the top plate surface 11 are dropped below the top plate 1. Can be used for this purpose.

  As shown in FIGS. 1, 2, 3 and 4, the desk D can be attached to the counter-use edge side which is the rear end side of the top plate 1 via the bracket 4 with the wiring duct 3 according to this embodiment. It is said. Specifically, the bracket 4 is used to support the wiring duct 3, and is a wiring duct support that supports the wiring end 3 and the insertion end 41 inserted into the internal space in the top plate body. Part 42. The bracket 4 shown in FIGS. 2 and 4 is a flat member made of a sheet metal material, and is vertically inserted from the insertion end 41 extending horizontally in the front-rear direction and the vicinity of the rear end of the insertion end 41. The wiring duct support portion 42 extending downward has a substantially inverted L shape in side view.

  As shown in FIGS. 3 and 4, the wiring duct 3 includes a duct body 31, a side plate body 32 provided with a support body 34 to be described later in the present embodiment, and a duct cover 33 as a cover body. . A rotating mechanism R having a catch 331 serving as a bearing and a pin 341 serving as a support shaft is formed in the vicinity of both sides of the duct cover 33 and the support 34 in the front-rear direction. By configuring each rotation mechanism R so that it can be attached and detached as appropriate, it is possible to take a closed posture C for holding the duct cover 33 substantially horizontally and a standing posture O for raising the duct cover 33. (FIG. 4).

  Thus, the wiring duct 3 according to the present embodiment has the standing maintenance means Y that can maintain the duct cover 33 in the standing posture O, and the falling prevention means Z that prevents the pin 341 from dropping from the catch 331 in the standing posture O. The support structure X which is the support structure of the cover body which concerns on this invention which comprises these is employ | adopted.

  Hereinafter, the support structure X employed in the support body 34 and the duct cover 33 constituting the wiring duct 3 will be described in detail with respect to the specific structure of the wiring duct 3.

  As shown in FIGS. 2, 3, and 4, the wiring duct 3 mainly includes a duct main body 31 that forms a wiring space, side plate bodies 32 that block both longitudinal ends of the duct main body 31, and the wiring space from above. A duct cover 33 that can be closed is provided.

  The duct body 31 is formed by bending a sheet metal material, for example, and the front wall 312 and the rear wall 313 rise vertically from both front and rear edges of the bottom wall 311, and the bottom wall 311, the front wall 312 and the rear wall 313 are channels in a cross-sectional view. It is the member which makes a shape. The height of the front wall 312 is set lower than the height of the rear wall 313.

  As shown in FIG. 2, the side plate body 32 closes both sides of the duct body 31 and also plays a role of engaging with the bracket 4. The pair of side plate bodies 32 is mainly constituted by a side wall 321 directly joined to the duct main body 31 by welding, for example, and a side cover 327 covering the outer end of the side wall 321. The side wall 321 is formed with a transparent window 322 through which the wiring space can be seen from the outside, and a bolt hole 326 is formed on the outward surface in the vicinity of the upper end to couple other members to the front and rear. . 2 shows a mode in which the side cover 327 is attached to the side wall 321 and the bolt hole 326 is concealed by using the corner cap 329. However, the side cover 327 and the corner cap 329 are illustrated in the drawings subsequent to FIG. The illustration is omitted.

  As shown in FIG. 3, the duct cover 33 is configured by assembling a cover main body 330, two catches 331 that constitute the rotation mechanism R described above, and a cover end 332. The cover main body 330, the two catches 331, and the cover end 332 are configured symmetrically in cross-sectional view.

  The cover main body 330 is formed, for example, by extrusion molding of aluminum or the like, and its longitudinal direction is substantially matched with the width direction of the desk D. And it has a symmetrical shape in the side sectional view as in the case of the support 34 described later.

  The catch 331 is attached by being fitted from the end surface of the cover main body 330. The catch 331 serving as a bearing is made of a resin having a shape opened in a U shape in a sectional view. Specifically, the inside of the U-shape is generally rigid, and the pin 341 is inserted and removed while elastically energizing the pin 341 in the closed posture C, and the pivot wall 331a that favorably pivots the pin 341. An allowable elastic claw 331b is provided. Furthermore, in the pivot wall 331a, an interference portion 331a1 is preferentially raised at a portion that can come into contact with the pin 341 during a tilting operation described later.

  The cover end 332 is made of, for example, a resin that covers the end portion of the cover main body 330 in a state where the end portion of the cover main body 330 has an outer shape substantially similar to that of the cover main body 330 in a side sectional view. In addition, when the cover end 332 is attached, the catch 331 is brought into contact with the catch 331, thereby positioning and catching the catch 331 in the insertion / extraction direction. The inner surface 332a1 of the side edge 332a of the cover end 332 plays a role of actually contacting the contact portion 342 of the support 34 described above.

  And as shown in FIG. 3, the support body 34 which concerns on this invention is comprised by inner side upper end vicinity of the side wall 321 in the side plate body 32. As shown in FIG.

  The support 34 will be described in detail. Two pins 341 for supporting the duct cover 33 are provided so as to protrude, and a contact portion 342 that can contact the duct cover 33 is provided below the pins 341. In the present embodiment, the pins 341 and the contact portion 342 are configured to be symmetrical in side view.

  The pin 341 is separated from the side plate 32 by fixing a member separate from the side plate 32 from which the two pins 341 are projected, for example, so that only the pin 341 is exposed from the inside of the side plate 32. It is a protruding one. The pin 341 is made of a highly rigid metal.

  The abutting portion 342 is formed by projecting a sheet metal constituting the side wall 321 into a substantially trapezoidal shape by, for example, pressing, and an inclined surface on the upper surface 342a side of the projected portion is a side edge of the duct cover 33 described later. The contact surface 342a1 can contact the inner surface of the portion. Further, the lower end 342a2 of the upper surface 342a is formed so as to substantially match the shape of the side edge 33a of the duct cover 33, which becomes a tilting fulcrum described later, and the portion outside the lower end 342a2 inhibits the rotation of the duct cover 33. It is formed in an impossible shape.

  Here, the wiring duct 3 according to the present embodiment has an upright maintaining means Y and a drop-off preventing means Z with respect to the two rotation mechanisms R having the pins 341 and the catches 331 provided on the duct cover 33 and the support 34. Are provided.

  Next, operation | movement of the duct cover 33 is shown using FIG.4, FIG.5, FIG.6 and FIG. 7, and the standing-up maintenance means Y and drop-off prevention means Z are explained in full detail.

  4 and 5 show the duct cover 33 in the closed posture C. FIG. The duct cover 33 can be rotated from the closed posture C to two standing postures O indicated by broken lines in FIG. At this time, since the shape of the catch 331 is substantially U-shaped in cross-section, the pin 341 is separated from the catch 331 in the substantially vertical direction at the rotation start end, so that the pivoting state can be preferably released. In this closed position C, the elastic claws 331b formed on both catches 331 are in a state of elastically biasing the pins 341 from the side so as to face each other. It is in a state of being stably supported by the support body 34 without any problem. Further, from this closed position C, the duct cover 33 is lifted upward while holding the upper surface of the duct cover 33 horizontally, and the pins 341 are removed from both catches 331 at the same time. Can be completely separated from the support 34.

  FIG. 6 shows a standing posture O in which the duct cover 33 is erected substantially vertically. At this time, the duct cover 33 can hold the standing posture O by its own weight by the standing maintenance means Y. More specifically, when the duct cover 33 is rotated from the closed position C to the standing position O in the rotation range of the duct cover 33, the center of gravity 33W of the duct cover 33 does not first exceed the axis 341a around which the duct cover 33 rotates. If the external force on the duct cover is released as it is in the lying region R1, the duct cover 33 will fall back to the closed posture C again. However, in this embodiment, the duct cover 33 is rotated beyond the lodging region R1, the center of gravity 33W of the duct cover 33 exceeds the axis 341a, and the duct cover 33 falls in the anti-closing direction opposite to the closing posture C. In the obtained stable holding region R2, the contact surface 342a1 of the contact portion 342 contacts the inner surface 33a1 of the side edge portion 33a of the duct cover 33, more specifically, the inner surface 332a1 of the side edge portion 332a of the cover end 332. 33 is stably maintained in the standing posture O by the weight of the duct cover 33 without falling down to the closed posture C. At this time, the center of gravity 33W of the duct cover 33 in the standing posture O is positioned in the vicinity of the shaft center 341a although it exceeds the shaft center 341a. It can be taken. The metal contact portion 342 and the resin cover end 332 are in contact with each other, so that the contact between the contact portion 342 made of metal and the cover main body 330 is avoided and both wear and It is assumed that exhaustion is effectively avoided.

  Further, when an external force is further applied to the duct cover 33 from the standing posture O indicated by an imaginary line in FIG. 7, the drop-off preventing means Z according to the present embodiment acts as follows. That is, the duct cover 33 tilts a contact point between the lower end 342a2 of the upper surface 342a of the contact portion 342 already in contact in the standing posture O and the side edge 33a2 of the duct cover 33, strictly speaking, the side edge 332a2 of the cover end 332. However, in such a tilting operation, the interference portion 331a1 which is a part of the pivot wall 331a of the catch 331 is preferentially abutted against the pin 341, so that the duct is removed from the illustrated posture. The cover 33 can hardly be tilted in the opposite direction to the closed posture C, and the duct cover 33 can be effectively prevented from falling off the support 34.

  Next, as shown in FIG. 8, another desk D ′ is arranged opposite to the rear end side of the wiring duct 3 and the wiring duct 3 is provided on the opposite side of the desks D and D ′. In this case, the duct cover 33 is configured to be in the standing posture O from both the front and rear sides of the desk as described above, so that the wiring duct 3 can be preferably used from the use edge side of both desks D and D ′. Further, when the duct cover 33 is in the closed posture C, the tops 1 and 1 of the desks D and D ′ and the upper surface of the duct cover 33 can be substantially flush with each other to provide a large work area. It becomes.

  As described above, the support structure X of the duct cover 33 employed in the wiring duct 3 according to the present embodiment includes the pin 341 provided on the support body 34 and the pin 341 provided on the duct cover 33 by the rotation mechanism R. Assuming that the catch 331 is a bearing 331 that is detachably pivoted, the standing maintenance means Y that can maintain the duct cover 33 in the standing posture O, and the pin 341 falling off the catch 331 in the standing posture O. It is assumed that it comprises dropout prevention means Z for preventing.

  By adopting such a configuration, the duct cover 33 can be stably in the standing posture O without depending on structures other than the duct cover 33 and the support body 34, and the duct cover 33 can be set in the standing posture O. Can be effectively avoided from falling off unexpectedly. By doing so, it can be stably opened and closed without restricting the installation location.

  Further, since the abutment portion 342 of the support 34 is disposed at a position where the duct cover 33 can hold the standing posture O by its own weight, the standing posture O is stabilized without providing any special member on the support 34. Can be maintained.

  Then, the duct cover 33 is moved in the stable region R2 where the center of gravity 33W of the duct cover 33 exceeds the axis 341a of the pin 341. Since the contact portion 342 is arranged at a position where the contact portion 342 can contact the duct cover 33 in the stable holding region R2, the weight of the duct cover 33 is effectively used to the closed posture C. The standing posture O is suitably maintained in a state where it is difficult to return. In addition, since the standing posture O is configured without using a structure such as friction or engagement, a highly durable support structure X is realized.

  Further, the contact portion 342 is in contact with the duct cover 33 so that the center of gravity 33W of the duct cover 33 in the standing posture O is positioned at a predetermined position in the vicinity of the pin 341 in the stable holding region R2. By setting the standing posture O to a posture in which the duct cover 33 is disposed almost vertically, the duct cover 33 is prevented from excessively protruding from the closed state to the side beyond the pin 341, and the duct cover 33 is made compact in a top view. Achieved standing posture O. In particular, since the duct cover 33 can be set to the lodging region R1 with a smaller force, it can be easily returned to the closed posture C.

  Specifically, since the contact portion 342 is provided with a contact surface 342a that contacts the inner surface 33a1 of the side edge portion 33a of the duct cover 33, the standing posture O is further increased by contacting the inner surface 33a1 with the surface. It can be maintained stably. Strictly speaking, the contact surface 342a is configured to contact the inner surface 332a1 of the side edge 332a of the cover end 332 made of resin, so that the metal contact surface 342a and the cover body 330 are effectively avoided from being damaged. In addition, it can be surely locked to the duct cover 33. Further, in the present embodiment, the abutting surface 342a substantially below the pin 341 is brought into contact with the inner surface 33a1 of the duct cover 33 located on the outer side of the rotation mechanism R, so that the abutting without taking up a space. The portion 342 is provided, and as a result, the support 34 itself is configured to be compact.

  On the other hand, by providing the interference portion 331a1 that can prevent the duct cover 33 in the standing posture O from tilting with any part of the contact portion 342 as a tilting fulcrum, the pin 341 and the catch 331 are unexpectedly moved in the standing posture O. It is possible to effectively avoid detachment. Further, by providing the interference portion 331a1 in the rotation mechanism R that is always set closest to the duct cover 33 and the support body 34, that is, either the pin 341 or the catch 331, the tilt of the duct cover 33 is effectively prevented. It is supposed to be possible. In addition, the interference portion 331a1 is formed by locally protruding from the pivot wall 331a, thereby effectively limiting the operation range of the tilting operation that can be recognized as looseness for the user.

  Since the tilt fulcrum described above is set so as to be located at or near the side edge 33a2 of the duct cover 33, the tilt fulcrum is greatly separated from the interference portion 331a1, and the interference portion 331a1 due to the tilt of the duct cover 33 is set. The amount of movement is set to be large, and the interference portion 331a1 can be suitably operated by a slight tilt.

  Furthermore, the catch 331 is made of resin and arranged on the duct cover 33 side, so that the duct cover 33 is configured to be lighter and wear and fatigue caused by the collision with the pins 341 are effectively avoided. .

  By making the catch 331 substantially U-shaped in cross-section, providing the interference portion 331a1 on the pivot wall 331a that is the inner wall of the catch 331, and providing the elastic claw 331b that allows insertion and removal of the pin 341 separately from the pivot wall 331a The catch 331 has a function as an interference part 331a1 constituting the drop-off prevention means Z and a function for suitably maintaining the closed posture C by using the elastic claw 331b.

  In the present embodiment, by arranging the rotation mechanisms R on both sides of the duct cover 33, the standing posture O can be suitably set from both sides of the duct cover 33. Furthermore, since the shapes of the duct cover 33 and the support 34 are configured symmetrically in cross-sectional view, the part sharing rate of each part constituting the duct cover 33 is improved and the production cost is reduced.

  In addition, when the catch 331 is in the closing posture C, the two pins 341 are elastically biased symmetrically from the sides, so that the pins 341 and the catch 331 can be easily detached, and the rattling in the closing posture C is achieved. Can be suitably eliminated. Further, if the engagement between the pin 341 and the catch 331 in either one of the rotation mechanisms R is released, the elastic claw 331b cannot elastically bias the pin 341, and the catch 331 preferably pivots the pin 341. This is a possible configuration.

  Then, the above-described support structure X of the duct cover 33 is adopted for the wiring duct 3 and the duct cover 33 is supported by the support body 34, thereby realizing the wiring duct 3 that can easily set the attachment location and can perform stable opening and closing. ing.

  Although the embodiment of the present invention has been described above, the specific configuration of each unit is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  In the above embodiment, the cover support structure according to the present invention is applied only to the wiring duct. However, as long as the cover body is provided, it can be applied to various structures such as a desk, a table, or other storage furniture. It is possible to adopt.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
