Description

本発明は、パネル付き机の配線装置に係わり、更に詳しくは配線機能を有する机の後部にバックパネル立設したパネル付き机の配線装置に関するものである。 The present invention relates to a wiring device for a desk with a panel, and more particularly to a wiring device for a desk with a panel in which a back panel is erected on the rear part of a desk having a wiring function.

従来から、机の天板上に立設するバックパネル、サイドパネルあるいは床面に設置するロングパネルとして、両側枠の上下端に上枠と下枠を連結するとともに、それらでパネル体を保持した構造ものは各種提供されている。そして、前記側枠、上枠及び下枠は、アルミ押出し型材を用いて構成することも周知である。 Conventionally, as a back panel standing on the top of the desk, a side panel or a long panel installed on the floor, the upper and lower frames are connected to the upper and lower ends of both side frames, and the panel body is held by them. Various structures are provided. And it is also well-known that the said side frame, an upper frame, and a lower frame are comprised using an aluminum extrusion type | mold material.

特許文献１には、パネルの下枠として、上部にパネル体を支持する基板を有し、該基板の両側縁に両側壁板を一体形成し、該両側壁板は下方に延び、下端部を内方へ若干湾曲させた形状とし、基板と両側壁板とで下方開放した開口溝を形成した断面形状のものが提供されている。前記側壁板の下端を内方へ湾曲させているのは、パネル全体の丸みを帯びた意匠性を統一するためであり、機能的には何ら意味をなさない。 Patent Document 1 has a substrate that supports a panel body at the top as a lower frame of the panel, and both side wall plates are integrally formed on both side edges of the substrate, the both side wall plates extend downward, and a lower end portion is formed. There is provided a cross-sectional shape in which an opening groove opened downward is formed by a substrate and both side wall plates, which is slightly curved inward. The reason why the lower end of the side wall plate is curved inward is to unify the rounded design of the entire panel, and does not make any sense functionally.

一方、天板の後端と幕板の上端部間に開口部を設け、その内部にコード受け部を設けるとともに、開口部に開閉可能に配線カバーを設けた配線機能付き机も各種提供されている。この場合、机の後端部には、バックパネルが立設され、前記配線カバーは該バックパネルに干渉されないように開閉可能に設けている。前記バックパネルは、その板厚の半分が机の後端部に重なった状態で立設されるので、その分だけ机の上面が狭くなることは避けられない。 On the other hand, various types of desks with a wiring function are also provided in which an opening is provided between the rear end of the top plate and the upper end of the curtain, a cord receiving portion is provided therein, and a wiring cover is provided in the opening so as to be opened and closed. Yes. In this case, a back panel is erected at the rear end of the desk, and the wiring cover is provided so as to be openable and closable so as not to interfere with the back panel. Since the back panel is erected in a state where half of its thickness is overlapped with the rear end of the desk, it is inevitable that the upper surface of the desk becomes narrower by that amount.

特許文献２には、前記天板の後端縁と所定距離を隔てた位置に、該後端縁と略平行に前記天板の左右方向の略全長にわたって設けられる支持部材と、該支持部材により、前記後端縁と略平行な水平軸まわりに回動可能に支持され、前記天板の左右方向の略全長にわたって設けられるカバー体と、該カバー体の前記天板の後端縁方向の両側端の少なくともどちらかに装着されたサイドキャップに設けた凸部が、前記支持部材に設けた凹部に弾性的に係合することにより、前記カバー体を開いて該カバー体が上方に略垂直となった状態において、該カバー体の位置を保持する保持手段とを備えた構造が開示されている。 In Patent Document 2, a support member provided over a substantially entire length in the left-right direction of the top plate at a position spaced a predetermined distance from the rear end edge of the top plate, substantially parallel to the rear end edge, and the support member 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 both sides of the cover body in the rear end edge direction of the top plate A convex portion provided on a side cap attached to at least one of the ends is elastically engaged with a concave portion provided on the support member, thereby opening the cover body so that the cover body is substantially vertically upward. The structure provided with the holding means which hold | maintains the position of this cover body in the state which became.

ここで、前記配線カバーを水平な閉止状態としたときには天板と略面一となり、略垂直な開放状態としたときには、前記バックパネルの前面に接近した状態となるが、当然、配線カバーの回動中心は前記バックパネルの前面より前側に設定する必要がある。また、バックパネルを立設したまま、配線カバーを着脱可能にするためにも、その着脱作業がバックパネルに干渉されないように、配線カバーの回動中心は前記バックパネルの前面より十分に前側に設定する必要がある。しかし、回動中心を前側に設定すると、配線カバーを開放した状態で配線作業に使用できる実効開口部が狭くなるといった不都合が生じる。 Here, when the wiring cover is in a horizontal closed state, it is substantially flush with the top plate, and when it is in a substantially vertical open state, it is close to the front surface of the back panel. The moving center needs to be set in front of the front surface of the back panel. Also, in order to make the wiring cover detachable with the back panel erected, the rotation center of the wiring cover should be sufficiently forward of the front surface of the back panel so that the attachment / detachment work is not interfered with the back panel. Must be set. However, when the center of rotation is set to the front side, there arises a disadvantage that the effective opening that can be used for wiring work becomes narrow with the wiring cover opened.

Also in this case, the horizontal width of the long panel 8 coincides with the horizontal width of the desk 1 and is erected close to the back of the desk 1. Similarly to the above, the side panel 9 is erected above the top plate 5 in a state where half of the plate thickness is overlapped with the top surface side end of the top plate 5, but the rear end position of the side panel 9 is Matches the rear end of desk 1. Therefore, the side panel 9 is attached to the rear position by the half of the thickness of the back panel 7 or the long panel 8 as compared with the above case. Also in this case, the connecting member 37 is expanded in the fitting groove 30 on the front side of the side frame 22 of the long panel 8 and the fitting groove 30 on the inner side of the rear end surface of the side frame 22 behind the side panel 9. The projecting portions 38 and 38 are inserted and connected from above.

Yes.

前記配線カバー１２は、図６〜図１０に示すように、前記配線機構部１０の上部開口部１１Ａを開閉すべく、両端部を端部支承具１３，１３で回転可能に支持するとともに、該端部支承具１３に対して着脱を容易にした構造である。また、前記配線カバー１２は、水平な閉止状態と略垂直な開放状態とに弾性的に状態保持できるようになっている。 As shown in FIGS. 6 to 10, the wiring cover 12 rotatably supports both ends by end support members 13 and 13 to open and close the upper opening portion 11 A of the wiring mechanism portion 10, and This is a structure in which attachment / detachment with respect to the end support 13 is facilitated. The wiring cover 12 can be elastically held in a horizontal closed state and a substantially vertical open state.

具体的には、前記配線カバー１２は、図６に示すように、金属製の板金加工品あるいはアルミニウム又は合成樹脂の押出し成形品からなるカバー本体４９の両端に、合成樹脂製の端部材５０，５０を取付けて構成している。本実施形態のカバー本体４９は、板金加工品であり、前記配線機構部１０の上部開口部１１Ａを塞ぐ閉塞板５１の後端部に下方斜め前方に向いた斜板５２を形成するとともに、該斜板５２の前縁に立上片５３を形成し、閉塞板５１の前縁に断面略Ｚ字形に折曲した前片５４を形成し、また閉塞板５１の後部で開放状態のとき前記バックパネル７の下枠２４の傾斜板３４が作る後退空間に収容される位置に、後側が高くなった段部５５を形成して曲げ強度を高めた構造としている。そして、前記カバー本体４９の前片５４には合成樹脂製の縁部材５６を嵌着し、また前記立上片５３の切断縁を隠蔽するように合成樹脂製の保護部材５７を嵌着している。前記縁部材５６は、前方へ張り出した軟質片５８を二色成形によって一体形成している。前記配線カバー１２を閉じた状態でも、前記軟質片５８が変形して前記天板５の後端との間に配線コードを引き出せるようにしている。 Specifically, as shown in FIG. 6, the wiring cover 12 has synthetic resin end members 50, 25 at both ends of a cover body 49 made of a metal sheet metal processed product or an extruded product of aluminum or synthetic resin. 50 is attached. The cover body 49 of the present embodiment is a sheet metal processed product, and forms a swash plate 52 that faces obliquely downward and forward at the rear end portion of the closing plate 51 that closes the upper opening portion 11A of the wiring mechanism portion 10. A rising piece 53 is formed on the front edge of the swash plate 52, a front piece 54 bent in a substantially Z-shaped cross section is formed on the front edge of the closing plate 51, and the back when the rear portion of the closing plate 51 is open. A stepped portion 55 having a higher rear side is formed at a position accommodated in a receding space formed by the inclined plate 34 of the lower frame 24 of the panel 7 to increase the bending strength. A synthetic resin edge member 56 is fitted to the front piece 54 of the cover main body 49, and a synthetic resin protection member 57 is fitted so as to conceal the cutting edge of the rising piece 53. Yes. The edge member 56 integrally forms a soft piece 58 projecting forward by two-color molding. Even when the wiring cover 12 is closed, the soft piece 58 is deformed so that the wiring cord can be drawn out from the rear end of the top plate 5.

前記カバー本体４９の端部に嵌着する端部材５０は、図６に示すように、前記閉塞板５１、斜板５２及び前片５４で形成される空間内に嵌合し、カバー本体４９の側端縁を覆う鍔部５９を形成している。そして、前記端部材５０の外側面の後部には、下方斜め後方に解放した傾斜溝６０を形成するとともに、該傾斜溝６０の下方開放側の下側に第１係合凹部６１と上側に弾性的な第２係合凹部６２を形成し、更に外側面の前後中央部には下方へ向いた弾性的なリップ片６３を形成している。ここで、前記傾斜溝６０の深さは、前記第１係合凹部６１及び第２係合凹部６２よりも深く設定し、前記第１係合凹部６１及び第２係合凹部６２は傾斜溝６０に連通している。具体的には、前記傾斜溝６０の上端部を中心とした円弧溝を該傾斜溝６０に交差するように形成し、その円弧溝の傾斜溝６０より下方部分を前記第１係合凹部６１とし、円弧溝の傾斜溝６０より上方部分を前記第２係合凹部６２としたのである。また、前記第２係合凹部６２の一部を内外へ弾性変形可能な弾性片６４で構成している。そして、両側の端部材５０，５０は、反対称形である。 As shown in FIG. 6, the end member 50 fitted to the end portion of the cover main body 49 is fitted in the space formed by the closing plate 51, the swash plate 52 and the front piece 54, A flange 59 that covers the side edge is formed. The rear surface of the end member 50 is formed with an inclined groove 60 that is released obliquely rearwardly downward, and a first engaging recess 61 on the lower open side of the inclined groove 60 and elastic on the upper side. A second engaging recess 62 is formed, and an elastic lip piece 63 directed downward is formed in the front and rear central portion of the outer surface. Here, the depth of the inclined groove 60 is set deeper than the first engaging recess 61 and the second engaging recess 62, and the first engaging recess 61 and the second engaging recess 62 are inclined groove 60. Communicating with Specifically, an arc groove centering on the upper end of the inclined groove 60 is formed so as to intersect the inclined groove 60, and a portion below the inclined groove 60 of the arc groove is defined as the first engaging recess 61. The portion above the inclined groove 60 of the arc groove is the second engaging recess 62. Further, a part of the second engaging recess 62 is constituted by an elastic piece 64 that can be elastically deformed inward and outward. And the end members 50 and 50 on both sides are antisymmetric.

一方、前記端部支承具１３は、前記脚部材２の上面後端部あるいは前記袖キャビネット３の上面の外側後端部に取付けて、両側の端部支承具１３，１３間に配置した前記配線カバー１２を開閉可能に支持する。具体的には、図６に示すように、前記端部支承具１３の内側面後部には、上側に前記傾斜溝６０に係合して配線カバー１２を回動可能に支持する軸部６５を突設するとともに、その下方に前記第１係合凹部６１又は第２係合凹部６２に係合する規制ピン６６を突設し、更に内側面中央部には配線カバー１２の閉止時に前記リップ片６３の先端部を係止する突部６７と、該リップ片６３を突部６７まで案内する円弧状の案内部６８を形成している。ここで、前記軸部６５の突出高さは、前記規制ピン６６の突出高さよりも高く設定し、前記軸部６５が、前記第１係合凹部６１又は第２係合凹部６２に進入しないようにしている。また、前記案内部６８の円弧面に対する前記軸部６５の中心までの距離は、下方になるにつれて短くなるように設定している。そして、前記突部６７の先端と前記軸部６５の中心までの距離が最短となっている。 On the other hand, the end support 13 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 13 on both sides. The cover 12 is supported so that it can be opened and closed. Specifically, as shown in FIG. 6, a shaft portion 65 that engages with the inclined groove 60 and supports the wiring cover 12 so as to be rotatable is provided on the rear side of the inner surface of the end support 13. A restricting pin 66 that protrudes and engages with the first engagement recess 61 or the second engagement recess 62 is provided below the protrusion, and the lip piece is provided at the center of the inner surface when the wiring cover 12 is closed. A protrusion 67 that locks the tip of 63 and an arcuate guide 68 that guides the lip piece 63 to the protrusion 67 are formed. Here, the protruding height of the shaft portion 65 is set to be higher than the protruding height of the restriction pin 66 so that the shaft portion 65 does not enter the first engagement recess 61 or the second engagement recess 62. I have to. The distance from the arc surface of the guide portion 68 to the center of the shaft portion 65 is set to be shorter as it goes downward. The distance from the tip of the projection 67 to the center of the shaft 65 is the shortest.

そして、図７に示すように、前記配線カバー１２の両側の端部材５０，５０に形成した傾斜溝６０，６０の方向を略垂直に向けた状態で、後部を上部開口部１１Ａ内に落とし込むことによって、前記傾斜溝６０，６０に、両側に取付けた前記端部支承具１３，１３のそれぞれの軸部６５と規制ピン６６を受け入れ、該軸部６５を傾斜溝６０の上端部に回動可能に係合させる。この際に、前記傾斜溝６０は前記第１係合凹部６１及び第２係合凹部６２よりも深く形成し、前記軸部６５を規制ピン６６よりも突出高さを高く設定しているので、前記軸部６５が不意に第２係合凹部６２や第１係合凹部６１に進入することがなく、スムーズに傾斜溝６０の上端部まで係合させることができる。その後、前記配線カバー１２を、前記軸部６５を中心に下方へ回動させて略水平状態にすると、前記規制ピン６６が第１係合凹部６１に係合するとともに、前記リップ片６３の先端部が案内部６８で案内され、該リップ片６３が弾性変形しながら突部６７を超えて該突部６７の下側に係止する。この状態で、前記配線カバー１２が配線機構部１０の上部開口部１１Ａを閉止した状態を維持する（図８参照）。この閉止状態では、前記規制ピン６６に第１係合凹部６１が係合しているので、配線カバー１２の後部を持ち上げても外れることは全くない。また、前記リップ片６３の先端が突部６７に弾性係合しているので、配線カバー１２をガタつきなく保持できる。 Then, as shown in FIG. 7, the rear portion is dropped into the upper opening 11 A in the state where the inclined grooves 60, 60 formed in the end members 50, 50 on both sides of the wiring cover 12 are oriented substantially vertically. Thus, the shaft portions 65 and the regulation pins 66 of the end support members 13 and 13 attached to both sides can be received in the inclined grooves 60 and 60, and the shaft portions 65 can be rotated to the upper end portions of the inclined grooves 60. Engage with. At this time, the inclined groove 60 is formed deeper than the first engaging recess 61 and the second engaging recess 62, and the shaft portion 65 is set to have a protruding height higher than the restriction pin 66. The shaft portion 65 does not unexpectedly enter the second engagement recess 62 or the first engagement recess 61, and can be smoothly engaged to the upper end portion of the inclined groove 60. Thereafter, when the wiring cover 12 is rotated downward about the shaft portion 65 to be in a substantially horizontal state, the restriction pin 66 engages with the first engagement recess 61 and the tip of the lip piece 63 The portion is guided by the guide portion 68, and the lip piece 63 is locked to the lower side of the protrusion 67 beyond the protrusion 67 while being elastically deformed. In this state, the wiring cover 12 maintains the state where the upper opening 11A of the wiring mechanism unit 10 is closed (see FIG. 8). In this closed state, since the first engagement recess 61 is engaged with the restriction pin 66, the rear portion of the wiring cover 12 does not come off at all. Further, since the tip of the lip piece 63 is elastically engaged with the protrusion 67, the wiring cover 12 can be held without rattling.

そして、前記配線カバー１２の前片５４と縁部材５６の間の段部に指をかけて持ち上げ、前記リップ片６３の先端と突部６７の係合を解除すると、該リップ片６３の先端は案内部６８に弾性圧接された状態となるので、該リップ片６３の弾性復元力によって案内部６８を摺動して配線カバー１２の前部を上方へ若干持ち上げる。その状態になると、前記縁部材５６に指を掛けることができ、前記配線カバー１２を、前記軸部６５を中心に上方へ回動させて、前記規制ピン６６を傾斜溝６０が通過して該配線カバー１２を略垂直状態にすると、前記規制ピン６６に第２係合凹部６２が弾性的に係合して開放状態を維持する（図９参照）。この開放状態で前記配線カバー１２を持ち上げても、前記規制ピン６６に第２係合凹部６２が係合しているので外れることはない。 When the step between the front piece 54 and the edge member 56 of the wiring cover 12 is lifted with a finger and the engagement between the tip of the lip piece 63 and the projection 67 is released, the tip of the lip piece 63 becomes Since it is in a state of being elastically pressed against the guide portion 68, the guide portion 68 is slid by the elastic restoring force of the lip piece 63 and the front portion of the wiring cover 12 is slightly lifted upward. In this state, a finger can be put on the edge member 56, the wiring cover 12 is rotated upward about the shaft portion 65, and the inclined groove 60 passes through the regulation pin 66. When the wiring cover 12 is set to a substantially vertical state, the second engagement recess 62 is elastically engaged with the restriction pin 66 and the open state is maintained (see FIG. 9). Even if the wiring cover 12 is lifted in this open state, the second engaging recess 62 is engaged with the restricting pin 66, so that it does not come off.

また、前記配線カバー１２を開放状態から下方へ押し下げると、前記規制ピン６６と第２係合凹部６２との弾性係合状態が解除されて自由回転するが、図１０に示すように、前記リップ片６３の先端が前記案内部６８に当接し、当該配線カバー１２の下方への回転が弱まり、やがて釣り合って停止する。その状態から、前記配線カバー１２の手前側を強制的に押し下げると、前記リップ片６３の先端が前記突部６７を乗り越えてその下方側に弾性的に係止するのである（図８参照）。 Further, when the wiring cover 12 is pushed down from the open state, the elastic engagement state between the restriction pin 66 and the second engagement recess 62 is released and freely rotates. However, as shown in FIG. The tip of the piece 63 comes into contact with the guide portion 68, and the downward rotation of the wiring cover 12 is weakened, and eventually balances and stops. When the front side of the wiring cover 12 is forcibly pushed down from this state, the tip of the lip piece 63 gets over the protrusion 67 and is elastically locked to the lower side (see FIG. 8).

また、図１及び図６に示すように、前記配線カバー１２が閉止状態で、前縁部を当止して撓みを防止するために、前記天板５の後端部の左右中間部にブロック状の中間支持部材４８を取付けて、その上面の当止部６９に前記縁部材５６を当止するようにしている。前記中間支持部材４８を天板５の後端に取付ける構造は任意であるが、本実施形態では中間支持部材４８の前側上部に前記天板５の後端下部に係合する凹陥部７０を形成し、該凹陥部７０の上部両側に上向きフック７１，７１を突設するとともに、該凹陥部７０の下部中央部に上向き係合爪７２を突設している。一方、前記天板５の後端面の適所には、前記中間支持部材４８の上向きフック７１，７１を挿入する角孔（図示せず）を形成するとともに、前記天板５の下面後端部に前記上向き係合爪７２を係合する係合孔（図示せず）を形成している。前記中間支持部材４８を取付ける個数は任意であり、天板５の横幅の広狭に応じて決定する。 Further, as shown in FIGS. 1 and 6, when the wiring cover 12 is closed, the front cover 5 is blocked at the left and right intermediate portions of the rear end of the top plate 5 in order to prevent the bending. An intermediate support member 48 is attached, and the edge member 56 is abutted against the abutment portion 69 on the upper surface thereof. Although the structure for attaching the intermediate support member 48 to the rear end of the top plate 5 is arbitrary, in this embodiment, a recessed portion 70 that engages with the lower end of the rear end of the top plate 5 is formed at the upper front side of the intermediate support member 48. In addition, upward hooks 71, 71 project on both sides of the upper portion of the recessed portion 70, and an upward engaging claw 72 projects on the lower central portion of the recessed portion 70. On the other hand, square holes (not shown) for inserting the upward hooks 71, 71 of the intermediate support member 48 are formed at appropriate positions on the rear end surface of the top plate 5, and at the rear lower end portion of the top plate 5. An engagement hole (not shown) for engaging the upward engagement claw 72 is formed. The number of the intermediate support members 48 to be attached is arbitrary, and is determined according to the width of the top plate 5.

前記バックパネル７の下枠２４は、前述のように、下方に開放した開口溝３３を形成し、該開口溝３３を形成する両側壁板３２，３２の下部が下方になるにつれて直線状に狭まるように傾斜板３４，３４となっている。従って、図７に示すように、前記配線カバー１２を両側の端部支承具１３，１３に装着する際に、前記カバー本体４９の閉塞板５１を前記傾斜板３４に略平行にして上部開口部１１Ａ内に挿入することができ、前記端部支承具１３の軸部６５と規制ピン６６が、前記バックパネル７の前面の直下近傍に位置していても、傾斜溝６０に軸部６５と規制ピン６６を受け入れることができる。つまり、前記軸部６５を最も後方に設定できるので、図９に示すように、前記配線カバー１２を略垂直に開放した状態では、該配線カバー１２をバックパネル７の表面に最接近状態にすることができ、それによって配線機構部１０の上部開口部１１Ａを大きく開放して、配線作業を容易に行うことができるのである。 As described above, the lower frame 24 of the back panel 7 forms the opening groove 33 that opens downward, and narrows linearly as the lower portions of the side wall plates 32 and 32 that form the opening groove 33 become lower. Thus, the inclined plates 34 and 34 are formed. Therefore, as shown in FIG. 7, when the wiring cover 12 is attached to the end supports 13 on both sides, the closing plate 51 of the cover main body 49 is made substantially parallel to the inclined plate 34 and the upper opening portion. 11A. Even if the shaft portion 65 and the restriction pin 66 of the end support 13 are located in the vicinity of directly below the front surface of the back panel 7, the shaft portion 65 and the restriction are formed in the inclined groove 60. Pin 66 can be received. That is, since the shaft portion 65 can be set to the rearmost position, as shown in FIG. 9, when the wiring cover 12 is opened substantially vertically, the wiring cover 12 is brought closest to the surface of the back panel 7. Thus, the upper opening portion 11A of the wiring mechanism unit 10 can be largely opened, and wiring work can be easily performed.

そして、図１１に示すように、前記配線カバー１２の閉塞板５１に設けた前記段部５５の段差を大きくし、該配線カバー１２を垂直に開放した状態で、該段部５５より下部を前記バックパネル７の下枠２４の傾斜板３４によって後退した部分に位置させることにより、軸部６５と傾斜溝６０の上端部による回動中心位置を更に後方位置に設定することができ、それにより開放状態で上部開口部１１Ａを更に広く開放することができ、配線作業が容易になるのである。また、前記配線カバー１２に段部５５を設けたことによるその他の効果としては、配線カバー１２の上に配線タップなどを配置するときの位置決め、配線カバー１２の裏面の保護部材５７の取付けの位置決め、配線カバー１２のカバー本体４９の強度アップなどを挙げることができる。 Then, as shown in FIG. 11, the step of the step portion 55 provided on the closing plate 51 of the wiring cover 12 is enlarged, and the lower portion of the step portion 55 is placed below the step portion 55 in a state where the wiring cover 12 is opened vertically. By positioning the back panel 7 at the portion retracted by the inclined plate 34 of the lower frame 24, the rotation center position by the shaft 65 and the upper end of the inclined groove 60 can be further set to the rear position. In this state, the upper opening 11A can be opened more widely, facilitating wiring work. In addition, other effects obtained by providing the wiring cover 12 with the stepped portion 55 include positioning when a wiring tap or the like is disposed on the wiring cover 12 and positioning of the protective member 57 on the back surface of the wiring cover 12. The strength of the cover body 49 of the wiring cover 12 can be increased.
