Description

  The present invention relates to an opening / closing support device for a wiring cover, and more particularly to an opening / closing support device for a wiring cover that opens and closes an upper opening of a wiring mechanism provided along a rear portion of a desk.

  Conventionally, various desks having a wiring function in which a wiring mechanism part is provided at the rear part of the top plate and a wiring cover that can be opened and closed at the upper opening part are provided. The wiring cover needs to be kept open during wiring work in the wiring mechanism and may need to be removed for convenience of wiring work, and is required to be removable. Of course, maintaining the closed state with the upper opening closed is also an important function.

  Patent Document 1 includes a rotation mechanism for supporting the cover body so that the cover body can be rotated between a closed posture in which the cover body can be supported substantially horizontally and an upright posture in which the cover body is raised from the support body. The rotation mechanism includes a support shaft provided on one of the cover body and the support body, and a bearing provided on the other side for removably supporting the support shaft. A support structure for a cover body, comprising: an upright maintaining means capable of maintaining the cover body in the upright posture; and a dropout prevention means for preventing the support shaft from falling off from the bearing in the upright posture. It is disclosed. Here, the bearing has a structure in which an elastic claw is provided so as to elastically engage the support shaft. Specifically, the standing maintaining means includes a contact portion that can lock the cover body in the standing posture, and the cover body in the support body can hold the standing posture by its own weight. It is arranged in the position. Further, the drop-off preventing means rotates the interference portion that can prevent the cover body in the standing posture from tilting in a direction opposite to the closing posture with any part of the contact portion as a tilting fulcrum. It is provided in the mechanism.

  Further, Patent Document 2 discloses a support member provided over a substantially entire length in the left-right direction of the top plate at a position separated from the rear end edge of the top plate by a predetermined distance and substantially parallel to the rear end edge. A cover body rotatably supported about a horizontal axis substantially parallel to the rear end edge and provided over substantially the entire length in the left-right direction of the top plate, and a rear end edge direction of the top plate of the cover body The convex portion provided on the side cap mounted on at least one of the both side ends of the cover elastically engages the concave portion provided on the support member, so that the cover body is opened and the cover body is substantially upward. A structure provided with holding means for holding the position of the cover body in a vertical state is disclosed.

  However, the one described in Patent Document 1 is that the support shaft is only elastically engaged with the bearing. Therefore, if the elastic force of the elastic claw is weak, it is easily removed, and if the elastic force is strong, it can be detached. A strong force is required at the time. There is also a problem of durability due to aging of the elastic nail. Furthermore, the standing support means for the cover body is such that the center of gravity of the cover body is held at a position where it has passed the rotational top dead center, so if it suddenly contacts the cover body during wiring work, it can easily be closed. There is a problem of rotating. Furthermore, since the cover body is only received by the support bodies at both ends, when the width of the desk is wide, the cover body becomes longer accordingly and there is a problem of bending of the central portion. In order to prevent the cover body from being bent, the bending rigidity must be increased, but the weight increases and the cost increases.

  On the other hand, the one described in Patent Document 2 is provided with a pair of receivers on both the left and right sides of the opening for the wiring mechanism part provided at the rear part of the desk top plate, and holding support members made of an aluminum extrusion mold material on both receivers. The first cover body of the wiring cover, which is also made of an aluminum extrusion mold, is slidably engaged in the left-right direction to the engaging portion formed on the front edge of the supporting member, and is connected so as to be rotatable at an angle of 90 °. Two engagement recesses provided on the arcuate side surface of the member, and a protrusion formed at the front end of the circumscribed surface provided on the side cap of the first cover body, respectively, in the horizontal closed state and the vertical open state, respectively. Since the structure is configured to be elastically engaged and maintain the state, the wiring cover will not fall off in any state, but the structure is not easily removable. Further, since the support member and the first cover body are rotatably engaged over the entire length, if both the members are bent and deformed, the rotation operation cannot be smoothly performed. For this reason, a structure is adopted in which an intermediate receiver is provided between the two receivers between the rear end of the top plate and the curtain plate to hold the support member. However, since this intermediate receptacle does not directly receive the wiring cover, if the front part of the wiring cover is pushed, a slight deflection occurs.

  As shown in FIGS. 3 to 5, the wiring cover 9 rotatably supports both ends by end support members 10 and 10 so as to open and close the upper opening 13 of the wiring mechanism section 6, and This is a structure in which the end support 10 is easily attached and detached. The wiring cover 9 can be elastically held in a horizontal closed state and a substantially vertical open state.

  As shown in FIG. 3, the wiring cover 9 is constructed by attaching synthetic resin end members 17 and 17 to both ends of a cover body 16 made of a metal sheet metal processed product or an extruded product of aluminum or synthetic resin. doing. The cover main body 16 of the present embodiment is a sheet metal processed product, and forms an inclined plate 19 facing obliquely forward and downward at the rear end portion of the closing plate 18 that closes the upper opening 13 of the wiring mechanism portion 6. A rising piece 20 is formed on the front edge of the inclined plate 19 and a front piece 21 bent in a substantially Z-shaped cross section is formed on the front edge of the closing plate 18 to increase the bending strength. Then, a synthetic resin edge member 22 is fitted to the front piece 21 of the cover body 16, and a synthetic resin protection member 23 is fitted so as to conceal the cutting edge of the rising piece 20. Yes. The edge member 22 is integrally formed with a soft piece 24 projecting forward by two-color molding. Even when the wiring cover 9 is closed, the soft piece 24 is deformed so that the wiring cord can be drawn between the rear end of the top plate 5.

  As shown in FIGS. 3, 4, and 6 to 8, the end member 17 fitted to the end of the cover body 16 is in a space formed by the closing plate 18, the inclined plate 19, and the front piece 21. And a flange portion 26 that covers the side edge of the cover main body 16 is formed. An inclined groove 27 released obliquely downward and rearward is formed in the rear portion of the outer surface of the end member 17, and the first engaging recess 28 and elastically upward on the lower open side of the inclined groove 27. A second engaging recess 29 is formed, and an elastic lip piece 30 facing downward is formed at the front and rear central portions of the outer surface. Here, the depth of the inclined groove 27 is set deeper than the first engaging recess 28 and the second engaging recess 29, and the first engaging recess 28 and the second engaging recess 29 are inclined groove 27. Communicating with Specifically, an arc groove centering on the upper end portion of the inclined groove 27 is formed so as to intersect the inclined groove 27, and a portion below the inclined groove 27 of the arc groove is defined as the first engagement recess 28. The portion above the inclined groove 27 of the arc groove is the second engaging recess 29. Further, a part of the second engaging recess 29 is constituted by an elastic piece 31 that can be elastically deformed inward and outward. And the end members 17 and 17 on both sides are antisymmetric.

  On the other hand, the end support 10 is attached to the rear end of the upper surface of the leg member 2 or the outer rear end of the upper surface of the sleeve cabinet 3, and is arranged between the end supports 10, 10 on both sides. The cover 9 is supported so that it can be opened and closed. Specifically, as shown in FIG. 4 to FIG. 6 and FIG. 9, the wiring cover 9 can be rotated by engaging with the inclined groove 27 on the rear side of the inner side surface of the end support 10. A shaft 32 to be supported protrudes, and a regulation pin 33 that engages with the first engagement recess 28 or the second engagement recess 29 is provided below the support shaft 32, and the wiring cover 9 is provided at the center of the inner surface. A protrusion 34 that locks the tip of the lip piece 30 when the lip piece 30 is closed and an arcuate guide part 35 that guides the lip piece 30 to the protrusion 34 are formed. Here, the protruding height of the shaft portion 32 is set to be higher than the protruding height of the restriction pin 33 so that the shaft portion 32 does not enter the first engagement recess 28 or the second engagement recess 29. I have to. The distance from the arc surface of the guide portion 35 to the center of the shaft portion 32 is set to be shorter as it goes downward. The distance from the tip of the projection 34 to the center of the shaft 32 is the shortest.

  Then, as shown in FIG. 12, the rear portion is dropped into the upper opening 13 in the state where the inclined grooves 27, 27 formed in the end members 17, 17 on both sides of the wiring cover 9 are oriented substantially vertically. Thus, the shaft portions 32 and the restriction pins 33 of the end support members 10 and 10 attached to both sides are received in the inclined grooves 27 and 27, and the shaft portions 32 can be rotated to the upper end portions of the inclined grooves 27. Engage with. At this time, the inclined groove 27 is formed deeper than the first engagement recess 28 and the second engagement recess 29, and the shaft portion 32 is set to have a protruding height higher than the restriction pin 33. The shaft portion 32 can be smoothly engaged to the upper end portion of the inclined groove 27 without unexpectedly entering the second engagement recess 29 or the first engagement recess 28. Thereafter, when the wiring cover 9 is rotated downward about the shaft portion 32 to be in a substantially horizontal state, the restriction pin 33 engages with the first engagement recess 28 and the tip of the lip piece 30 The part is guided by the guide part 35, and the lip piece 30 is elastically deformed and is locked to the lower side of the protrusion 34 beyond the protrusion 34. In this state, the wiring cover 9 maintains a state where the upper opening 13 of the wiring mechanism section 6 is closed (see FIG. 13). In this closed state, the first engaging recess 28 is engaged with the restriction pin 33, so that even if the rear portion of the wiring cover 9 is lifted, it does not come off at all. Further, since the tip of the lip piece 30 is elastically engaged with the protrusion 34, the wiring cover 9 can be held without rattling.

  Then, when the step between the front piece 21 of the wiring cover 9 and the edge member 22 is lifted with a finger and the engagement between the tip of the lip piece 30 and the protrusion 34 is released, the tip of the lip piece 30 becomes Since it is in a state of being elastically pressed against the guide portion 35, the guide portion 35 is slid by the elastic restoring force of the lip piece 30 to slightly lift the front portion of the wiring cover 9 upward. In this state, it is possible to put a finger on the edge member 22, rotate the wiring cover 9 about the shaft portion 32, and the inclined groove 27 passes through the regulation pin 33 to pass the When the wiring cover 9 is set to a substantially vertical state, the second engagement recess 29 is elastically engaged with the restriction pin 33 and the open state is maintained (see FIG. 14). Even if the wiring cover 9 is lifted in this open state, the second engaging recess 29 is engaged with the restricting pin 33 so that it does not come off.

  Further, when the wiring cover 9 is pushed down from the open state, the elastic engagement state between the restriction pin 33 and the second engagement recess 29 is released and freely rotates. However, as shown in FIG. The tip of the piece 30 comes into contact with the guide portion 35, the downward rotation of the wiring cover 9 is weakened, and eventually balances and stops. When the front side of the wiring cover 9 is forcibly pushed down from this state, the tip of the lip piece 30 gets over the protrusion 34 and is elastically locked to the lower side (see FIG. 13).

  4, 10, 16, and 17, the wiring cover 9 is closed, and the left and right sides of the rear end of the top plate 5 are prevented in order to stop the front edge and prevent bending. A block-shaped intermediate support member 11 is attached to the intermediate portion, and the edge member 22 is abutted against the abutment portion 36 on the upper surface thereof. Although the structure for attaching the intermediate support member 11 to the rear end of the top plate 5 is arbitrary, in this embodiment, a concave portion 37 that engages with the rear end lower portion of the top plate 5 is formed on the front upper side of the intermediate support member 11. In addition, upward hooks 38, 38 are provided on both sides of the upper portion of the recessed portion 37, and an upward engaging claw 39 is provided on the lower central portion of the recessed portion 37. On the other hand, square holes 40, 40 for inserting the upward hooks 38, 38 of the intermediate support member 11 are formed at appropriate positions on the rear end surface of the top plate 5, and the upward face is formed at the rear end of the lower surface of the top plate 5. An engagement hole 41 for engaging the engagement claw 39 is formed. The number of the intermediate support members 11 to be attached is arbitrary, and is determined according to the width of the top plate 5.

  When the top plate 5 is wide and the end supports 10 and 10 on both sides have a wide span, the wiring cover 9 becomes too long, so that it is divided into a plurality of wiring covers 9 and 9. In that case, as shown in FIGS. 5, 7, 11, 16, and 17, in order to rotatably support the inside of each wiring cover 9, 9, an intermediate support 12 is attached to the intermediate support member 11. Connect detachably. The intermediate support 12 has a support plate 43 extending rearward from the central portion of the main body 42 connected to the intermediate support member 11 so as to rotatably support the wiring covers 9 and 9. On both side surfaces of the support plate 43, a shaft portion 44, a restriction pin 45, a protrusion portion 46, and a guide portion 47 having the same functions as the shaft portion 32, the restriction pin 33, the protrusion portion 34, and the guide portion 35 are formed. ing.

  The intermediate support member 12 is detachably connected to the intermediate support member 11 as shown in FIGS. 5, 7, 10 and 11, with the back panel above the top end of the top plate 5. In order to be able to connect even if 7 exists, it was set as the structure which mutually engages from a side. The back panel 7 is in a state where half of the thickness of the back panel 7 overlaps the rear upper part of the desk 1, and in order to prevent front and rear see-through, only a slight gap is generated so that there is no gap with the top surface of the desk 1. There is no standing up. In such a situation, in order to totally block the upper opening 13 of the wiring mechanism portion 6 continuously formed above the curtain plate 4, the rear end portion of the wiring cover 9 is provided on the back panel. It is necessary to invade down to 7. Of course, since the back panel 7 may not be used, it is necessary to cover the rear end of the desk 1 with the wiring cover 9. Accordingly, in order to enable the intermediate support member 12 to be connected to the intermediate support member 11 by a side engagement operation, a connecting recess 48 is formed in the rear portion of the intermediate support member 11 and the intermediate support member is formed. At the front part of the twelve main body portions 42, a connecting convex portion 49 is provided projecting from the connecting concave portion 48 so as to slide from the side. More specifically, the connecting recess 48 of the intermediate support member 11 is a side-viewed L-shaped groove that is open on the left and right sides and closed on the other side. Is forming. The connecting projection 49 of the intermediate support 12 is L-shaped in a side view, and is engaged with the connecting recess 48 from the side and when fully engaged, the connecting projection 49 One end of the engaging portion abuts against the back portion of the connecting recess 48, and the engaging claw 50 engages with the other end so that it cannot be easily removed.

  The lower frame 51 of the back panel 7 is formed with inclined plates 53 and 53 so that an opening groove 52 is formed below and both side wall plates forming the opening groove 52 are linearly narrowed downward. Therefore, as shown in FIG. 12, when the wiring cover 9 is attached to the end bearings 10 and 10 on both sides, or when the wiring cover 9 is attached to the end bearing 10 and the intermediate bearing 12, the cover body 16 The closing plate 18 can be inserted into the upper opening 13 so as to be substantially parallel to the inclined plate 53, and the shaft 32 and the restricting pin 33 of the end support 10 or the shaft of the intermediate support 12 can be used. Even if the portion 44 and the restriction pin 45 are located in the vicinity of the position immediately below the front surface of the back panel 7, the shaft portion 32 and the restriction pin 33 or the shaft portion 44 and the restriction pin 45 can be received in the inclined groove 27. . That is, since the shaft portion 32 can be set to the rearmost position, as shown in FIGS. 14 and 18, when the wiring cover 9 is opened substantially vertically, the wiring cover 9 is closest to the surface of the back panel 7. Thus, the upper opening 13 of the wiring mechanism section 6 can be largely opened, and wiring work can be easily performed.

  Next, the internal structure of the wiring mechanism section 6 will be briefly described. As shown in FIGS. 12 and 13, the upper edge of the curtain plate 4 is bent forward to form an upper edge reinforcing frame 54, and between the upper edge reinforcing frame 54 of the curtain plate 4 and the wiring cover 9.
