Description

この発明は、長尺定規用連結装置に関し、例えば電動モータによって駆動される携帯用加工機をガイドする長尺定規を相互に連結する連結装置に関する。 The present invention relates to a coupling device for a long ruler, for example, to a coupling device for interconnecting long rulers that guide a portable processing machine driven by an electric motor.

特許文献１には、長尺定規と、長尺定規を相互に連結する連結装置が開示されている。長尺定規は、電動モータによって駆動される携帯用マルノコやルータ等の携帯用加工機を用いて直線的に長く精度の良い加工を行う場合に用いられる。先ず、長尺定規を加工材の上面に加工方向に延びるように設置し、長尺定規の上側に携帯用加工機を設置する。携帯用加工機を長尺定規にガイドさせつつ長尺定規の延びる方向に沿ってスライドさせて加工材を加工する。これにより直線的で長く精度の良い切断等の加工ができる。 Patent Document 1 discloses a long ruler and a coupling device for connecting the long ruler to each other. The long ruler is used when linearly long and highly accurate processing is performed using a portable processing machine such as a portable round saw or a router driven by an electric motor. First, a long ruler is installed on the upper surface of the processed material so as to extend in the processing direction, and a portable processing machine is installed on the upper surface of the long ruler. While guiding the portable processing machine to the long ruler, slide it along the extending direction of the long ruler to process the processed material. This makes it possible to perform linear, long and accurate cutting and other processing.

長尺定規は持ち運びをするとき等のことを考慮して、長手方向に相応の長さになっているが、使用時に複数の長尺定規を長手方向に連結する場合がある。長尺定規を長手方向に相互に連結する際に連結装置が用いられる。２つの長尺定規のそれぞれに形成された長手方向に延びる溝状のレールに跨ってバーを挿入する。バーには厚み方向に螺合するねじが設けられる。ねじを回転させることでねじがバーに対して厚み方向に進退する。ねじがレールの底面に向けて移動し、ねじによってバーがレールの底面から離れる方向に移動する。バーがレールの開口部から張り出す張出部に当たり、バーがレールに対して固定される。特許文献２には、特許文献１のねじの代わりに磁石を有する固定部材を備える長尺定規用連結装置が開示されている。 The long ruler has an appropriate length in the longitudinal direction in consideration of carrying it, etc., but a plurality of long rulers may be connected in the longitudinal direction at the time of use. A coupling device is used to couple long rulers to each other in the longitudinal direction. A bar is inserted across a longitudinally grooved rail formed on each of the two long rulers. The bar is provided with a screw that is screwed in the thickness direction. By rotating the screw, the screw moves back and forth in the thickness direction with respect to the bar. The screw moves toward the bottom of the rail, and the screw moves the bar away from the bottom of the rail. The bar hits the overhang overhanging the opening of the rail and the bar is fixed to the rail. Patent Document 2 discloses a coupling device for a long ruler including a fixing member having a magnet instead of the screw of Patent Document 1.

独国特許出願公開第１９９２３６４２号明細書German Patent Application Publication No. 19923642 独国実用新案出願公開第２０２０１３１０４５５５号明細書German Utility Model Application Publication No. 201310340555

特許文献１のねじや特許文献２の磁石を有する固定部材は、長尺定規に対して直接押し付けられる。そのためレールを傷つけてしまう場合がある。そのため長尺定規を傷つけることなく、長尺定規を相互に連結し、かつ操作性に優れる連結装置が従来必要とされている。 The fixing member having the screw of Patent Document 1 and the magnet of Patent Document 2 is directly pressed against the long ruler. Therefore, the rail may be damaged. Therefore, a coupling device that connects long rulers to each other without damaging the long ruler and has excellent operability has been conventionally required.

本発明の１つの特徴によると長尺定規用連結装置は、電動モータによって駆動する携帯用加工機をガイドする長尺定規を長手方向に相互に連結する。連結装置は、厚み方向に相互に重ねられる第１と第２のバーと、第１と第２のバーを厚み方向に相対的に移動可能に結合する結合部材と、第１のバーと第２のバーを厚み方向に移動させるように一端が第１のバーに螺合され他端が第２のバーに当接される固定部材を有する。第１と第２のバーが長尺定規の長手方向に延びる溝状のレールに挿入され、固定部材によって第１と第２のバーを厚み方向に引き離す。これにより第１と第２のバーがレールに取付けられる。 According to one feature of the present invention, the connecting device for a long ruler connects long rulers that guide a portable processing machine driven by an electric motor to each other in the longitudinal direction. The coupling device includes a first and second bars that are overlapped with each other in the thickness direction, a coupling member that connects the first and second bars so as to be relatively movable in the thickness direction, and a first bar and a second bar. It has a fixing member in which one end is screwed into the first bar and the other end is in contact with the second bar so as to move the bar in the thickness direction. The first and second bars are inserted into a grooved rail extending in the longitudinal direction of the long ruler, and the fixing member pulls the first and second bars apart in the thickness direction. This attaches the first and second bars to the rail.

したがって固定部材によって第１と第２のバーが厚み方向に引き離されてその間隔が広がる。その結果、第１と第２のバーの一方がレールの底面に押し付けられ、他方がレールの端縁から張り出す張出部に押し付けられる。そのため固定部材は、レールの底面に直接当たらない。このため長尺定規が固定部材によって傷つくことが防止される。また、第１のバーと第２のバーが相互に分離しないように結合部材によって結合されている。そのため連結装置を分離しない一体物として扱える。したがって連結装置によって容易に２つの長尺定規を相互に連結することができる。 Therefore, the fixing member pulls the first and second bars apart in the thickness direction to widen the distance between them. As a result, one of the first and second bars is pressed against the bottom surface of the rail, and the other is pressed against the overhanging portion protruding from the end edge of the rail. Therefore, the fixing member does not directly hit the bottom surface of the rail. Therefore, the long ruler is prevented from being damaged by the fixing member. Further, the first bar and the second bar are connected by a connecting member so as not to be separated from each other. Therefore, the coupler can be treated as an integral body without separation. Therefore, the two long rulers can be easily connected to each other by the coupling device.

他の特徴によると結合部材は、第１のバーの第１孔と第２のバーの第２孔を貫通するピン本体と、ピン本体の一端から径方向に張り出して第１のバーに対面する第１フランジ部と、ピン本体の他端から径方向に張り出して第２のバーに対面する第２フランジ部を有する。 According to another feature, the coupling member faces the pin body penetrating the first hole of the first bar and the second hole of the second bar, and the pin body projecting radially from one end of the pin body to face the first bar. It has a first flange portion and a second flange portion that projects radially from the other end of the pin body and faces the second bar.

したがって第１のバーと第２のバーは、第１フランジ部と第２フランジ部によって相互に分離しないように結合される。また第１のバーと第２のバーは、ピン本体によって厚み方向に所定の距離だけ相対的に移動できる。 Therefore, the first bar and the second bar are connected by the first flange portion and the second flange portion so as not to be separated from each other. Further, the first bar and the second bar can be relatively moved by a predetermined distance in the thickness direction by the pin body.

他の特徴によると結合部材は、第１または第２のバーの一方の孔を貫通するピン本体と、ピン本体の一端から径方向に張り出して一方の孔を備えるバーに対面するフランジ部と、ピン本体の他端において他方のバーに固定される先端固定部を有する。 According to other features, the coupling member includes a pin body that penetrates one hole of the first or second bar, and a flange portion that projects radially from one end of the pin body and faces the bar having the one hole. It has a tip fixing portion that is fixed to the other bar at the other end of the pin body.

したがって第１と第２のバーの一方は、フランジ部によって他方に対して分離しないように結合される。また一方のバーは、他方のバーに対して厚み方向に所定の距離だけ相対的に移動できる。したがって片方のバーのみが移動するため両方のバーが移動する場合に比べて動作自由度が少なく、連結装置を容易に扱うことができる。 Therefore, one of the first and second bars is joined by the flange portion so as not to be separated from the other. Further, one bar can move relative to the other bar by a predetermined distance in the thickness direction. Therefore, since only one bar moves, the degree of freedom of operation is smaller than when both bars move, and the coupling device can be easily handled.

次に、本発明の１つの実施形態を図１～図１１及び図１４に基づいて説明する。図５に示すように連結装置１は、略長方形の板状の２つの長尺定規２０を連結する。長尺定規２０は、図５及び図７に示すように長手方向と直交する両端の間に延びるレール２１，２２を有する。連結装置１の一端を長尺定規２０のレール２１，２２に挿入し、連結装置１の一端を他の長尺定規２０のレール２１，２２に挿入する。これにより連結装置１によって２つの長尺定規２０が連結される。長尺定規２０は、例えば従来の長尺定規と同様の構成の物を用いることができる。以下の説明において上下前後左右方向は、加工材の上面に加工方向に延びるように長尺定規２０を設置したときの加工作業する使用者を基準とする。また、レール２１，２２に連結装置１を挿入させた姿勢において、レール２１，２２の開口部側を外側、底面側を内側とする。 Next, one embodiment of the present invention will be described with reference to FIGS. 1 to 11 and 14. As shown in FIG. 5, the coupling device 1 connects two long rulers 20 having a substantially rectangular plate shape. The long ruler 20 has rails 21 and 22 extending between both ends orthogonal to the longitudinal direction as shown in FIGS. 5 and 7. One end of the coupling device 1 is inserted into the rails 21 and 22 of the long ruler 20, and one end of the coupling device 1 is inserted into the rails 21 and 22 of the other long ruler 20. As a result, the two long rulers 20 are connected by the coupling device 1. As the long ruler 20, for example, a long ruler having the same structure as that of a conventional long ruler can be used. In the following description, the up / down / front / back / left / right directions are based on the user who performs the processing work when the long ruler 20 is installed on the upper surface of the processed material so as to extend in the processing direction. Further, in the posture in which the coupling device 1 is inserted into the rails 21 and 22, the opening side of the rails 21 and 22 is the outside and the bottom side is the inside.

図１、図４及び図７に示すように、連結装置１は、第１のバー１０と、第２のバー１１と、複数（例えば２個）のピン１２と、複数（例えば４個）の六角穴付止ねじ１３を備える。第１のバー１０には、後述するピン１２の第１ピン本体１２ｂが貫通可能な第１孔１０ａと、六角穴付止ねじ１３を取り付け可能にねじ溝が切られているねじ孔１０ｂとが設けられている。第１孔１０ａとねじ孔１０ｂは、第１のバー１０の長手方向と交差する厚み方向、すなわち外側面１０ｃから内側面１０ｄへと向かう方向に第１のバー１０を貫通する。第１孔１０ａは、第１のバー１０の長手方向半分の領域内のそれぞれに１個ずつ設けられている。ねじ孔１０ｂは、各第１孔１０ａの長手方向の両側にそれぞれ１個ずつ設けられ、第１のバー１０に併せて４個設けられる。 As shown in FIGS. 1, 4 and 7, the coupling device 1 includes a first bar 10, a second bar 11, a plurality of (for example, two) pins 12, and a plurality (for example, four). A set screw 13 with a hexagon socket is provided. The first bar 10 has a first hole 10a through which the first pin body 12b of the pin 12, which will be described later, can penetrate, and a screw hole 10b in which a screw groove is cut so that a set screw 13 with a hexagonal hole can be attached. It is provided. The first hole 10a and the screw hole 10b penetrate the first bar 10 in the thickness direction intersecting the longitudinal direction of the first bar 10, that is, in the direction from the outer surface 10c to the inner side surface 10d. One first hole 10a is provided in each of the regions in the longitudinal half of the first bar 10. One screw hole 10b is provided on each side of each first hole 10a in the longitudinal direction, and four screw holes 10b are provided in combination with the first bar 10.

図１、図４及び図７に示すように、第２のバー１１には、後述するピン１２の第２ピン本体１２ｃが貫通可能な第２孔１１ａが設けられる。第２孔１１ａは、第２のバー１１の長手方向と交差する厚み方向、すなわち外側面１１ｂから内側面１１ｃへと向かう方向に第２のバー１１を貫通する。第２孔１１ａが貫通した内側面１１ｃ側には、第２孔１１ａの孔径よりも大きい凹み形状の内側凹部１１ｄが設けられる。第１のバー１０の内側面１０ｄと第２のバー１１の外側面１１ｂが対面するように第１のバー１０と第２のバー１１が厚み方向に相互に重ねられる。このとき２個の第１孔１０ａと２個の第２孔１１ａは、厚み方向に並ぶ。すなわち、第１孔１０ａと第２孔１１ａが貫通方向に並ぶことで、ピン１２が相互に重なった第１のバー１０と第２のバー１１を貫通することができる。 As shown in FIGS. 1, 4 and 7, the second bar 11 is provided with a second hole 11a through which the second pin body 12c of the pin 12, which will be described later, can penetrate. The second hole 11a penetrates the second bar 11 in the thickness direction intersecting the longitudinal direction of the second bar 11, that is, in the direction from the outer surface 11b to the inner surface 11c. On the inner side surface 11c side through which the second hole 11a penetrates, a recessed inner recess 11d larger than the hole diameter of the second hole 11a is provided. The first bar 10 and the second bar 11 are overlapped with each other in the thickness direction so that the inner side surface 10d of the first bar 10 and the outer surface 11b of the second bar 11 face each other. At this time, the two first holes 10a and the two second holes 11a are arranged in the thickness direction. That is, by arranging the first hole 10a and the second hole 11a in the penetrating direction, the pins 12 can penetrate the first bar 10 and the second bar 11 on which they overlap each other.

図２～図３に示すようにピン１２は、その両端に第１フランジ部１２ａと第２フランジ部１２ｄを備える。第１フランジ部１２ａと第２フランジ部１２ｄとの間には、第１ピン本体１２ｂと第２ピン本体１２ｃとが設けられる。ピン１２の各部は、第１フランジ部１２ａから、第１ピン本体１２ｂ、第２ピン本体１２ｃ、第２フランジ部１２ｄの順に並んでいる。第１ピン本体１２ｂは、第１孔１０ａを通過する。第１ピン本体１２ｂは、第１孔１０ａの孔の深さよりも長い軸方向の長さを有する。第２ピン本体１２ｃは、第２孔１１ａを通過する。第２ピン本体１２ｃは、第２孔１１ａの孔の深さよりも長い軸方向の長さを有する。 As shown in FIGS. 2 to 3, the pin 12 includes a first flange portion 12a and a second flange portion 12d at both ends thereof. A first pin main body 12b and a second pin main body 12c are provided between the first flange portion 12a and the second flange portion 12d. Each portion of the pin 12 is arranged in the order of the first pin main body 12b, the second pin main body 12c, and the second flange portion 12d from the first flange portion 12a. The first pin body 12b passes through the first hole 10a. The first pin body 12b has an axial length longer than the depth of the hole of the first hole 10a. The second pin body 12c passes through the second hole 11a. The second pin body 12c has an axial length longer than the depth of the hole of the second hole 11a.

図２～図３に示すように第１フランジ部１２ａは、ピン１２が第１孔１０ａを通過できないようにピン１２の径方向に第１ピン本体１２ｂから張り出す。第１フランジ部１２ａは第１孔１０ａよりも径の大きい円盤状である。第２フランジ部１２ｄはピン１２が第２孔１１ａを通過できないようにピン１２の径方向に第２ピン本体１２ｃから張り出す。第２フランジ部１２ｄは第２孔１１ａよりも径の大きい円盤状である。 As shown in FIGS. 2 to 3, the first flange portion 12a projects from the first pin body 12b in the radial direction of the pin 12 so that the pin 12 cannot pass through the first hole 10a. The first flange portion 12a has a disk shape having a diameter larger than that of the first hole 10a. The second flange portion 12d projects from the second pin body 12c in the radial direction of the pin 12 so that the pin 12 cannot pass through the second hole 11a. The second flange portion 12d has a disk shape having a diameter larger than that of the second hole 11a.

図３を参照して、第１のバー１０と第２のバー１１に対してピン１２を組み付ける手順を示す。組み付け前のピン１２には図３の仮想線に示すように第２フランジ部１２ｄが形成されていない。ピン１２を第１のバー１０の第１孔１０ａに挿入し、第１フランジ部１２ａが外側面１０ｃに当接する。次に、第１のバー１０の内側面１０ｄと第２のバー１１の外側面１１ｂが当接するように、ピン１２を第２孔１１ａに挿入する。 With reference to FIG. 3, a procedure for assembling the pin 12 to the first bar 10 and the second bar 11 is shown. As shown in the virtual line of FIG. 3, the second flange portion 12d is not formed on the pin 12 before assembly. The pin 12 is inserted into the first hole 10a of the first bar 10, and the first flange portion 12a abuts on the outer surface 10c. Next, the pin 12 is inserted into the second hole 11a so that the inner side surface 10d of the first bar 10 and the outer surface 11b of the second bar 11 come into contact with each other.

図３を参照するように第２孔１１ａを貫通したピン１２の先端をリベット等でかしめ、ピン１２の先端に第２フランジ部１２ｄを形成し、第２のバー１１が第１ピン本体部１２ｂと第２フランジ部１２ｄによって挟持される。これによって、第１のバー１０は第１フランジ部１２ａと第２のバー１１の間で移動可能になっている。すなわち、第１のバー１０と第２のバー１１は、厚み方向に相互に重なった状態で、互いが厚み方向に相対的に所定の量において移動可能に結合される。また、第１のバー１０と第２のバー１１は、第１フランジ部１２ａと第２フランジ部１２ｄによって互いに分離しない。 As shown in FIG. 3, the tip of the pin 12 penetrating the second hole 11a is crimped with a rivet or the like to form a second flange portion 12d at the tip of the pin 12, and the second bar 11 is the first pin main body portion 12b. And the second flange portion 12d. As a result, the first bar 10 can be moved between the first flange portion 12a and the second bar 11. That is, the first bar 10 and the second bar 11 are movably coupled to each other in a predetermined amount relative to each other in the thickness direction while being overlapped with each other in the thickness direction. Further, the first bar 10 and the second bar 11 are not separated from each other by the first flange portion 12a and the second flange portion 12d.

図３を参照するように第２フランジ部１２ｄを形成する場合、第１ピン本体１２ｂが第２のバー１１の外側面１１ｂに当接している。そのため第２フランジ部１２ｄを形成する際に、ピン１２の軸方向長さが短くなりすぎることを防止できる。そして第２ピン本体１２ｃの長さは、第２のバー１１の第２孔１１ａの長さと等しくなる。かくしてピン１２は、第２のバー１１に対して軸方向にほぼ移動できない状態で取付けられる。第２フランジ部１２ｄの軸方向長さは、内側凹部１１ｄの深さよりも短い。そしてピン１２は、第２のバー１１に対して軸方向に移動しない。したがって第２フランジ部１２ｄが第２のバー１１を超えて突出することが防止されている。 When the second flange portion 12d is formed as shown in FIG. 3, the first pin body 12b is in contact with the outer surface 11b of the second bar 11. Therefore, when forming the second flange portion 12d, it is possible to prevent the axial length of the pin 12 from becoming too short. The length of the second pin body 12c is equal to the length of the second hole 11a of the second bar 11. Thus, the pin 12 is attached so as to be substantially immovable in the axial direction with respect to the second bar 11. The axial length of the second flange portion 12d is shorter than the depth of the inner recess 11d. And the pin 12 does not move in the axial direction with respect to the second bar 11. Therefore, it is prevented that the second flange portion 12d protrudes beyond the second bar 11.

次に、図４に示すようにねじ孔１０ｂに六角穴付止ねじ１３を取り付ける。六角穴付止ねじ１３を六角スパナ等で回転操作して第１のバー１０と第２のバー１１の厚み方向に進行させる。図８及び図１１に示すように六角穴付止ねじ１３は、ねじ孔１０ｂを貫通し、第２のバー１１の内側面１１ｃを押す。第１のバー１０の外側面１０ｃから第２のバー１１の内側面１１ｃまでの厚み方向の長さが、レール２１の底面２１ａから張出部２１ｃまでの長さ、若しくはレール２２の底面２２ａから張出部２２ｃまでの長さよりも大きくなるまで六角穴付止ねじ１３を進行させる。 Next, as shown in FIG. 4, a hexagon socket set screw 13 is attached to the screw hole 10b. The set screw 13 with a hexagon socket is rotated by a hexagon wrench or the like to advance in the thickness direction of the first bar 10 and the second bar 11. As shown in FIGS. 8 and 11, the hexagon socket set screw 13 penetrates the screw hole 10b and pushes the inner side surface 11c of the second bar 11. The length in the thickness direction from the outer surface 10c of the first bar 10 to the inner surface 11c of the second bar 11 is the length from the bottom surface 21a of the rail 21 to the overhanging portion 21c, or from the bottom surface 22a of the rail 22. The hexagon socket set screw 13 is advanced until it becomes larger than the length up to the overhanging portion 22c.

図５に示すように長手方向に短く分けられた長尺定規２０のそれぞれには溝状のレール２１が設けられる。レール２１は、長尺定規２０の長手方向（前後方向）に延び、上方に向かって開口する。図７～図８及び図１０～図１１に示すようにレール２１の延びる方向（前後方向）と交差する断面形状は、上側が開口した略コ字形になっている。レール２１は、底面２１ａと、左右一対の側面２１ｂと、左右一対の側面２１ｂの上端部からそれぞれ左右方向に近づくように張り出す張出部２１ｃとを有する。左右一対の張出部２１ｃの間の開口部は、六角穴付止ねじ１３を回転操作させる六角棒スパナ等を挿入可能な幅を有する。図５及び図１４に示すように連結装置１は、レール２１の前端部若しくは後端部からレール２１に挿入され、レール２１に沿って前後方向にスライドされる。このとき図７及び図１１に示すように、ねじ孔１０ａが設けられた第１のバー１０が張出部２１ｃ側に、第２のバー１１が底面２１ａ側になる姿勢で連結装置１がレール２１に挿入される。張出部２１ｃは、レール２１に挿入された連結装置１の上方への抜けを防止する。 As shown in FIG. 5, each of the long rulers 20 divided short in the longitudinal direction is provided with a groove-shaped rail 21. The rail 21 extends in the longitudinal direction (front-back direction) of the long ruler 20 and opens upward. As shown in FIGS. 7 to 8 and 10 to 11, the cross-sectional shape intersecting the extending direction (front-back direction) of the rail 21 is a substantially U-shape with the upper side open. The rail 21 has a bottom surface 21a, a pair of left and right side surfaces 21b, and an overhanging portion 21c that projects from the upper ends of the pair of left and right side surfaces 21b so as to approach each other in the left-right direction. The opening between the pair of left and right overhanging portions 21c has a width in which a hexagon wrench or the like for rotating the hexagon socket set screw 13 can be inserted. As shown in FIGS. 5 and 14, the coupling device 1 is inserted into the rail 21 from the front end portion or the rear end portion of the rail 21, and is slid in the front-rear direction along the rail 21. At this time, as shown in FIGS. 7 and 11, the coupling device 1 is in a position where the first bar 10 provided with the screw hole 10a is on the overhanging portion 21c side and the second bar 11 is on the bottom surface 21a side. It is inserted in 21. The overhanging portion 21c prevents the coupling device 1 inserted in the rail 21 from coming off upward.

図５に示すように長尺定規２０のそれぞれには、長手方向に延び、下方に向かって開口した溝状のレール２２が設けられる。レール２２はレール２１と平行になるように設けられる。レール２２は、レール２１と開口方向が逆である以外は同様の構成を有する。図６～図１１に示すようにレール２２は、底面２２ａと、左右一対の側面２２ｂと、左右一対の側面２２ｂの下端部からそれぞれ左右方向に近づくように張り出す張出部２２ｃとを有する。図６、図９及び図１４に示すようにレール２２の前端部若しくは後端部から連結装置１が挿入される。図７～図８及び図１０～図１１に示すように張出部２２ｃは、レール２２に挿入された連結装置１の下方への抜けを防止する。 As shown in FIG. 5, each of the long rulers 20 is provided with a groove-shaped rail 22 extending in the longitudinal direction and opening downward. The rail 22 is provided so as to be parallel to the rail 21. The rail 22 has the same configuration as the rail 21 except that the opening direction is opposite to that of the rail 21. As shown in FIGS. 6 to 11, the rail 22 has a bottom surface 22a, a pair of left and right side surfaces 22b, and an overhanging portion 22c that projects from the lower ends of the pair of left and right side surfaces 22b so as to approach each other in the left-right direction. As shown in FIGS. 6, 9 and 14, the coupling device 1 is inserted from the front end or the rear end of the rail 22. As shown in FIGS. 7 to 8 and 10 to 11, the overhanging portion 22c prevents the coupling device 1 inserted in the rail 22 from coming off downward.

レール２１若しくはレール２２に挿入した連結装置１は、六角穴付止ねじ１３を六角棒スパナ等で回転操作することで、長尺定規２０に対して固定解除できる。図６～図８に示すように六角穴付止ねじ１３を第２のバー１１に対して厚み方向に退避させた場合、第１のバー１０の内側面１０ｄと第２のバー１１の外側面１１ｂを近づけることができる。これにより第１のバー１０の外側面１０ｃと第２のバー１１の内側面１１ｃとの厚み方向の長さがレール２１の底面２１ａから張出部２１ｃまでの長さ、若しくはレール２２の底面２２ａから張出部２２ｃまでの長さよりも短くなる。これにより連結装置１がレール２１，２２に対して固定解除され、連結装置１をレール２１，２２の延びる方向（前後方向）にスライドさせることができる。 The connecting device 1 inserted into the rail 21 or the rail 22 can be released from being fixed to the long ruler 20 by rotating the hexagon socket set screw 13 with a hexagon wrench or the like. As shown in FIGS. 6 to 8, when the hexagon socket set screw 13 is retracted with respect to the second bar 11 in the thickness direction, the inner side surface 10d of the first bar 10 and the outer surface of the second bar 11 are retracted. 11b can be brought closer. As a result, the length of the outer surface 10c of the first bar 10 and the inner surface 11c of the second bar 11 in the thickness direction is the length from the bottom surface 21a of the rail 21 to the overhanging portion 21c, or the bottom surface 22a of the rail 22. It is shorter than the length from the overhang to the overhanging portion 22c. As a result, the coupling device 1 is released from being fixed to the rails 21 and 22, and the coupling device 1 can be slid in the extending direction (front-back direction) of the rails 21 and 22.

図９～図１１に示すように六角穴付止ねじ１３を第２のバー１１に向けて移動させた場合、第１のバー１０の内側面１０ｄと第２のバー１１の外側面１１ｂとの間隔が六角穴付止ねじ１３によって広げられる。これにより第１のバー１０の外側面１０ｃと第２のバー１１の内側面１１ｃとの厚み方向の長さが長くなる。外側面１０ｃが張出部２１ｃ，２２ｃに当接し、内側面１１ｃが底面２１ａ，２２ａに当接する。その結果、第１のバー１０と第２のバー１１がレール２１，２２の溝内で互いに突っ張る。かくして連結装置１がレール２１，２２に固定される。ピン１２の前後両側のねじ孔１０ｂの両側で六角穴付止ねじ１３を第２のバー１１に対して厚み方向に進行させる。これにより連結装置１がレール２１，２２に対してより強固に固定される。 When the hexagon socket set screw 13 is moved toward the second bar 11 as shown in FIGS. 9 to 11, the inner surface 10d of the first bar 10 and the outer surface 11b of the second bar 11 The spacing is widened by the hexagon socket set screw 13. As a result, the length of the outer surface 10c of the first bar 10 and the inner surface 11c of the second bar 11 in the thickness direction becomes longer. The outer side surface 10c abuts on the overhanging portions 21c and 22c, and the inner side surface 11c abuts on the bottom surfaces 21a and 22a. As a result, the first bar 10 and the second bar 11 stretch against each other in the grooves of the rails 21 and 22. Thus, the coupling device 1 is fixed to the rails 21 and 22. Hexagon socket head set screws 13 are advanced in the thickness direction with respect to the second bar 11 on both sides of the screw holes 10b on both front and rear sides of the pin 12. As a result, the coupling device 1 is more firmly fixed to the rails 21 and 22.

図５に示すようにレール２２の上側には長手方向に延出する凸部２４が形成される。図１４に示すように長尺定規２０は、加工材Ｗの上側に設置される。長尺定規２０の上側に設置される携帯用加工機３０の下部には、凸部２４に対応する長手方向に延出する溝部３１が形成される。この溝部３１を凸部２４に係合するように載せ、携帯用加工機３０を凸部２４に沿って加工進行方向にスライドさせる。これにより携帯用加工機３０がレール２２の延びる方向に沿って移動して、直線的で長い切断等の加工がなされる。長尺定規２０に載せられた携帯用加工機３０が必要以上に滑らないように、図５に示すようにレール２１とレール２２との間の長尺定規２０の上面には、携帯用加工機３０の傷つきを防ぐとともに摩擦抵抗を低減するシート２３が設けられる。 As shown in FIG. 5, a convex portion 24 extending in the longitudinal direction is formed on the upper side of the rail 22. As shown in FIG. 14, the long ruler 20 is installed on the upper side of the processed material W. A groove 31 extending in the longitudinal direction corresponding to the convex portion 24 is formed in the lower portion of the portable processing machine 30 installed on the upper side of the long ruler 20. The groove 31 is placed so as to engage with the convex portion 24, and the portable processing machine 30 is slid along the convex portion 24 in the processing progress direction. As a result, the portable processing machine 30 moves along the extending direction of the rail 22, and processing such as straight and long cutting is performed. As shown in FIG. 5, the portable processing machine 20 is placed on the upper surface of the long ruler 20 between the rails 21 and 22 so that the portable processing machine 30 mounted on the long ruler 20 does not slip more than necessary. A sheet 23 is provided to prevent the 30 from being scratched and to reduce the frictional resistance.

以上説明したように連結装置１は、レール２１及びレール２２に挿入され、六角穴付止ねじ１３が第２のバー１１に向けて移動される。これにより第１のバー１０と第２のバー１１の厚み方向の間隔が広がる。かくして第１のバー１０と第２のバー１１がレール２１，２２の溝内で互いに突っ張り、連結装置１がレール２１，２２の溝内に固定される。このとき六角穴付止ねじ１３が底面２１ａ，２２ａに直接接触しない。長尺定規２０に対して直接接触する第１のバー１０の外側面１０ｃや第２のバー１１の内側面１１ｃは、接触面積が大きいため接触面圧が小さくなる。したがって連結装置１を長尺定規２０に固定する際、長尺定規２０が傷つくことを防ぐことができる。 As described above, the coupling device 1 is inserted into the rail 21 and the rail 22, and the hexagon socket set screw 13 is moved toward the second bar 11. As a result, the distance between the first bar 10 and the second bar 11 in the thickness direction is widened. Thus, the first bar 10 and the second bar 11 are stretched against each other in the grooves of the rails 21 and 22, and the coupling device 1 is fixed in the grooves of the rails 21 and 22. At this time, the hexagon socket set screw 13 does not come into direct contact with the bottom surfaces 21a and 22a. Since the outer surface 10c of the first bar 10 and the inner surface 11c of the second bar 11 that are in direct contact with the long ruler 20 have a large contact area, the contact surface pressure is small. Therefore, when the coupling device 1 is fixed to the long ruler 20, it is possible to prevent the long ruler 20 from being damaged.

第１のバー１０と第２のバー１１が分離しないように、ピン１２の第１フランジ部１２ａと第２フランジ部１２ｄとの間に第１のバー１０と第２のバー１１が挟まれるように結合している。したがって第１のバー１０と第２のバー１１がばらばらにならず、連結装置１を一体として扱うことができる。そのため２つの長尺定規２０を連結装置１によって容易に連結することができる。 The first bar 10 and the second bar 11 are sandwiched between the first flange portion 12a and the second flange portion 12d of the pin 12 so that the first bar 10 and the second bar 11 are not separated. Is bound to. Therefore, the first bar 10 and the second bar 11 do not fall apart, and the coupling device 1 can be treated as one. Therefore, the two long rulers 20 can be easily connected by the coupling device 1.

内側面１０ｄと外側面１１ｂとの間隔には一定の自由度がある。具体的には、内側面１０ｄと外側面１１ｂとが当接する状態から、外側面１１ｂと内側面１１ｃとの厚み方向の長さがレール２１の底面２１ａから張出部２１ｃまでの長さ、若しくはレール２２の底面２２ａから張出部２２ｃまでの長さよりも大きくなる状態まで変更させることができる。したがって第１のバー１０と第２のバー１１が相互に分離しないように結合された状態で、第１のバー１０と第２のバー１１をその厚み方向に相対的に移動させることができる。
There is a certain degree of freedom in the distance between the inner surface 10d and the outer surface 11b. Specifically, the length of the outer surface 11b and the inner surface 11c in the thickness direction is the length from the bottom surface 21a of the rail 21 to the overhanging portion 21c from the state where the inner surface 10d and the outer surface 11b are in contact with each other. The length can be changed to be larger than the length from the bottom surface 22a of the rail 22 to the overhanging portion 22c. Therefore, the first bar 10 and the second bar 11 can be relatively moved in the thickness direction in a state where the first bar 10 and the second bar 11 are connected so as not to be separated from each other.

次に、他の実施形態を図１２に基づいて説明する。図１２に示す形態における連結装置２は、第２のバー１１に一体に形成されたピン１２を有する。ピン１２は、第１ピン本体１２ｂと第１フランジ部１２ａを有するものの、図３に示す第２ピン本体１２ｃと第２フランジ部１２ｄを有さない。図１２に示す第２のバー１１には図３に示す第２孔１１ａが形成されていない。ピン１２は、第１のバー１０の第１孔１０ａに対応する位置において第２のバー１１に一体に設けられる。第１のバー１０と第２のバー１１を組み付ける前のピン１２には仮想線に示すように第１フランジ部１２ａが形成されていない。第１フランジ部１２ａは、第１孔１０ａを貫通したピン１２の先端をリベット等でかしめることで形成される。図１２に示す連結装置２のその他の構成は図３等に示す連結装置１と同様である。 Next, another embodiment will be described with reference to FIG. The coupling device 2 in the form shown in FIG. 12 has a pin 12 integrally formed with the second bar 11. Although the pin 12 has the first pin main body 12b and the first flange portion 12a, the pin 12 does not have the second pin main body 12c and the second flange portion 12d shown in FIG. The second bar 11 shown in FIG. 12 does not have the second hole 11a shown in FIG. The pin 12 is integrally provided with the second bar 11 at a position corresponding to the first hole 10a of the first bar 10. As shown in the virtual line, the first flange portion 12a is not formed on the pin 12 before assembling the first bar 10 and the second bar 11. The first flange portion 12a is formed by crimping the tip of the pin 12 penetrating the first hole 10a with a rivet or the like. Other configurations of the coupling device 2 shown in FIG. 12 are the same as those of the coupling device 1 shown in FIG. 3 and the like.

六角穴付止ねじ１３を回転させて第２のバー１１に対して厚み方向に進退させるとき、第１のバー１０のみが第２のバー１１とピン１２に対して厚み方向に移動する。すなわち第２のバー１１に対して移動しないピン１２に案内されて第１のバー１０が移動する。そのため第１のバー１０が第２のバー１１に対して安定良く移動し、第１のバー１０と第２のバー１１の間隔を安定良く変更できる。 When the hexagon socket set screw 13 is rotated to advance and retreat in the thickness direction with respect to the second bar 11, only the first bar 10 moves in the thickness direction with respect to the second bar 11 and the pin 12. That is, the first bar 10 moves by being guided by the pin 12 that does not move with respect to the second bar 11. Therefore, the first bar 10 can move stably with respect to the second bar 11, and the distance between the first bar 10 and the second bar 11 can be changed stably.

次に、さらに他の実施形態を図１３に基づいて説明する。図１３に示す連結装置３は、第１のバー１０に一体とされたピン１２を有する。ピン１２は、第２ピン本体１２ｃと第２フランジ部１２ｄを有するものの、図３に示す第１ピン本体１２ｂと第１フランジ部１２ａを有さない。図１３に示す第１のバー１０には図３に示す第１孔１０ａが形成されていない。ピン１２は、第２のバー１１の第２孔１１ａに対応する位置において第１のバー１０に一体に設けられる。図１３に示す連結装置３のその他の構成は図３等に示す連結装置１と同様である。 Next, still another embodiment will be described with reference to FIG. The coupling device 3 shown in FIG. 13 has a pin 12 integrated with the first bar 10. Although the pin 12 has the second pin main body 12c and the second flange portion 12d, the pin 12 does not have the first pin main body 12b and the first flange portion 12a shown in FIG. The first bar 10 shown in FIG. 13 does not have the first hole 10a shown in FIG. The pin 12 is integrally provided with the first bar 10 at a position corresponding to the second hole 11a of the second bar 11. Other configurations of the coupling device 3 shown in FIG. 13 are the same as those of the coupling device 1 shown in FIG. 3 and the like.

六角穴付止ねじ１３を回転させて第２のバー１１に対して厚み方向に進退させるとき、第２のバー１１がピン１２とともに第１のバー１０に対して厚み方向に移動する。すなわち第１のバー１０に対して移動しないピン１２が第２のバー１１に案内されつつ第１のバー１０が移動する。そのため第１のバー１０が第２のバー１１に対して安定良く移動し、第１のバー１０と第２のバー１１の間隔を安定良く変更できる。 When the hexagon socket set screw 13 is rotated to advance and retreat in the thickness direction with respect to the second bar 11, the second bar 11 moves in the thickness direction with respect to the first bar 10 together with the pin 12. That is, the first bar 10 moves while the pin 12 that does not move with respect to the first bar 10 is guided by the second bar 11. Therefore, the first bar 10 can move stably with respect to the second bar 11, and the distance between the first bar 10 and the second bar 11 can be changed stably.

以上説明した本実施形態の連結装置１には種々変更を加えることができる。例えば、第１のバー１０と第２のバー１１はそれぞれの長さが異なっていてもよい。第１のバー１０と第２のバー１１は、張出部２１ｃ，２２ｃと当接する外側面１０ｃと、底面２１ａ，２２ａと当接する内側面１１ｃとが概ね平行となるように六角穴付止ねじ１３で調整可能であれば、ピン１２の軸方向から見て波形状やジグザグ形状等であってもよい。固定部材は六角穴付止ねじ１３に限らず、皿ねじやボルト等を用いてもよい。固定部材は、第２のバー１１に向けてその先端を付勢するばね等の弾性体を備えていても良い。弾性体は、固定部材が第２のバー１１に当接する力を高めることができる。 Various modifications can be made to the coupling device 1 of the present embodiment described above. For example, the first bar 10 and the second bar 11 may have different lengths. The first bar 10 and the second bar 11 have hexagon socket set screws so that the outer surface 10c that abuts on the overhanging portions 21c and 22c and the inner side surface 11c that abuts on the bottom surfaces 21a and 22a are substantially parallel to each other. If it can be adjusted by 13, it may have a wave shape, a zigzag shape, or the like when viewed from the axial direction of the pin 12. The fixing member is not limited to the hexagon socket set screw 13, and a countersunk screw, a bolt, or the like may be used. The fixing member may include an elastic body such as a spring that urges the tip of the second bar 11 toward the second bar 11. The elastic body can increase the force with which the fixing member abuts on the second bar 11.

第２フランジ部１２ｄは、図３に示すようにリベットでかしめて第２のバー１１に取付けられる。これに代えて例えばピン１２の端部を第２孔１１ａに圧入あるいは螺合させることでピン１２を第２のバー１１に組み付けてもよい。図１２のピン１２は、第２のバー１１に一体である。これに代えてピン１２の一端が第１のバー１０の第１孔１０ａに圧入あるいは螺合させることでピン１２を第１のバー１０に組み付けてもよい。第１のバー１０に設けるねじ孔１０ｂの個数や長尺定規２０に設けるレール２１，２２の個数等を適宜増やすことで、長尺定規２０を長手方向に相互により強固に連結させる構成としてもよい。 The second flange portion 12d is attached to the second bar 11 by caulking with rivets as shown in FIG. Instead of this, for example, the pin 12 may be assembled to the second bar 11 by press-fitting or screwing the end portion of the pin 12 into the second hole 11a. The pin 12 in FIG. 12 is integrated with the second bar 11. Alternatively, the pin 12 may be assembled to the first bar 10 by press-fitting or screwing one end of the pin 12 into the first hole 10a of the first bar 10. By appropriately increasing the number of screw holes 10b provided in the first bar 10 and the number of rails 21 and 22 provided in the long ruler 20, the long ruler 20 may be more firmly connected to each other in the longitudinal direction. ..
