It is fixed by the screw 36A on the front side. The lower front ends of the side plates 35, 35 are formed in accordance with the side view shapes of the locking portion 38A and the claw portion 39.

一方、係止板３２の後端側では、２つの第１レバー４１と第２レバー４２とからなる係止部３８Ｂが設けられている。
まず、第１レバー４１は、側面視がＬ字状で、係止板３２の前後方向の中央よりやや後寄りの位置で、ネジ３６Ｂによって中間部が回転可能に連結される。第１レバー４１の後端部は、係止板３２の後端との間に設けられたコイルバネ４３によって、係止板３２から離れる下向き方向に付勢されている。第１レバー４１の中間部には、図７に示すように、係止板３２側に突出して係止板３２の下面に当接し、コイルバネ４３の付勢による回転を規制する突起部４４が突設されている。
また、第１レバー４１の前端部には、図８（Ａ）にも示すように、突起部４４による回転規制位置で台本体４の後側の被係止部８Ｂに下方から係止可能な第１爪部４５が形成されている。さらに、第１レバー４１の左右方向の中央には、後端部を除いて左右に分割するスリット４６が前後方向に形成されて、スリット４６を形成する第１レバー４１の左右の内面には、図８（Ｂ）にも示すように、前端がネジ３６Ｂより後方に位置する一対の凹部４７，４７が形成されて、凹部４７，４７の前端には、回転規制位置で上向きとなる段状の第１ストッパ４８，４８がそれぞれ形成されている。 On the other hand, on the rear end side of the locking plate 32, a locking portion 38B including two first levers 41 and a second lever 42 is provided.
First, the first lever 41 has an L-shape in the side view, and the intermediate portion is rotatably connected by the screw 36B at a position slightly rearward from the center of the locking plate 32 in the front-rear direction. The rear end portion of the first lever 41 is urged downward away from the locking plate 32 by a coil spring 43 provided between the rear end portion of the locking plate 32. As shown in FIG. 7, a protrusion 44 that projects toward the locking plate 32 and comes into contact with the lower surface of the locking plate 32 to regulate rotation due to the bias of the coil spring 43 protrudes from the middle portion of the first lever 41. It is installed.
Further, as shown in FIG. 8A, the front end portion of the first lever 41 can be locked from below to the locked portion 8B on the rear side of the base body 4 at the rotation restriction position by the protrusion 44. The first claw portion 45 is formed. Further, in the center of the first lever 41 in the left-right direction, slits 46 for dividing left and right except for the rear end portion are formed in the front-rear direction, and on the left and right inner surfaces of the first lever 41 forming the slit 46, As shown in FIG. 8B, a pair of recesses 47, 47 whose front ends are located behind the screw 36B are formed, and the front ends of the recesses 47, 47 have a stepped shape that faces upward at the rotation restriction position. The first stoppers 48 and 48 are formed, respectively.

第２レバー４２は、第１レバー４１のスリット４６内に収容される側面視Ｌ字状の板体で、中間部が、ネジ３６Ｂよりも後方且つ上側の位置で、左右方向のピン５０によって回転可能に連結される。第２レバー４２の後端部は、ピン５０に巻回されて一端が係止板３２に、他端が後端部に係止するトーションバネ５１によって、第１レバー４１と同様に係止板３２から離れる下向き方向に付勢されている。
また、第２レバー４２におけるピン５０の下側で左右の側面には、左右に突出する第２ストッパ５２，５２が設けられている。この第２ストッパ５２は、第１レバー４１の回転規制位置では、図７及び図８（Ｂ）にも示すように、ピン５０から下向きに延びる姿勢となって、第１レバー４１の内面の凹部４７，４７の前端縁に当接するようになっている。この状態で第２レバー４２は、トーションバネ５１の付勢に抗して、後端部をスリット４６から下方へ突出させる。この回転規制位置で第２ストッパ５２は、第１ストッパ４８の上側で上下方向の直線状に並び、下面を第１ストッパ４８に近接させている。
さらに、第２レバー４２の前端部には、図８（Ａ）にも示すように、回転規制位置で台本体４の後側の被係止部８Ｂに下方から係止可能な第２爪部５３が形成されている。 The second lever 42 is a side view L-shaped plate house accommodated in the slit 46 of the first lever 41, and the intermediate portion is rotated by a pin 50 in the left-right direction at a position rearward and above the screw 36B. Can be connected. The rear end of the second lever 42 is wound around the pin 50 and one end is locked to the locking plate 32, and the other end is locked to the rear end by a torsion spring 51, which is the same as the first lever 41. It is urged downward away from 32.
Further, second stoppers 52 and 52 projecting to the left and right are provided on the left and right side surfaces below the pin 50 of the second lever 42. At the rotation restriction position of the first lever 41, the second stopper 52 is in a posture of extending downward from the pin 50 as shown in FIGS. 7 and 8 (B), and is recessed on the inner surface of the first lever 41. It comes into contact with the front edge of 47, 47. In this state, the second lever 42 causes the rear end portion to protrude downward from the slit 46 against the urging of the torsion spring 51. At this rotation restriction position, the second stopper 52 is arranged in a straight line in the vertical direction on the upper side of the first stopper 48, and the lower surface is brought close to the first stopper 48.
Further, as shown in FIG. 8A, the front end portion of the second lever 42 has a second claw portion that can be locked from below to the locked portion 8B on the rear side of the base body 4 at the rotation restriction position. 53 is formed.

よって、回転規制位置から第１レバー４１の後端部のみを握り込んで上側へ回転させると、凹部４７の前端に第２ストッパ５２が当接する第２レバー４２も同時に回転しようとするが、図９（Ａ）に示すように、第１ストッパ４８と第２ストッパ５２とが互いに当接するため、両レバー４１，４２の回転が規制される。この状態で第１爪部４５と第２爪部５３とは被係止部８Ｂから下方へ回転移動するものの、被係止部８Ｂから後方へは離間しないため、被係止部８Ｂからの脱却は阻止される。従って、係止力が低下したブラケット２０を台本体４に沿った任意のスライド位置へスライドさせることができる。スライド位置を決定後、第１レバー４１の後端部の握り込みを解除すれば、第１レバー４１が再び回転規制位置に戻って第１爪部４５を被係止部８Ｂに係止させるため、当該スライド位置でブラケット２０を位置決めできる。 Therefore, when only the rear end portion of the first lever 41 is grasped from the rotation restriction position and rotated upward, the second lever 42 in which the second stopper 52 abuts on the front end of the recess 47 also tries to rotate at the same time. As shown in 9 (A), since the first stopper 48 and the second stopper 52 come into contact with each other, the rotation of both levers 41 and 42 is restricted. In this state, the first claw portion 45 and the second claw portion 53 rotate downward from the locked portion 8B, but do not separate from the locked portion 8B rearward, so that the first claw portion 45 and the second claw portion 53 escape from the locked portion 8B. Is blocked. Therefore, the bracket 20 having a reduced locking force can be slid to an arbitrary slide position along the base body 4. After determining the slide position, if the gripping of the rear end portion of the first lever 41 is released, the first lever 41 returns to the rotation regulation position again and the first claw portion 45 is locked to the locked portion 8B. , The bracket 20 can be positioned at the slide position.

一方、第１レバー４１の後端部と第２レバー４２の後端部とを共に握り込んで上側へ回転させると、図９（Ｂ）に示すように、スリット４６から突出した第２レバー４２が先に回転して第２ストッパ５２を第１ストッパ４８との近接位置から離脱させるため、第１レバー４１も続いて回転させることができる。そして、第１レバー４１の回転中心であるネジ３６Ｂと、第２レバー４２の回転中心であるピン５０とのズレにより、第１ストッパ４８と第２ストッパ５２とは回転方向へ互いにずれたままとなるため、干渉は生じなくなる。よって、図９（Ｃ）に示すように、互いのロックが解除された第１レバー４１と第２レバー４２とを、第１爪部４５と第２爪部５３とが共に被係止部８Ｂから外れるまで回転させることができる。このままブラケット２０の後端を上側へ持ち上げれば、第１、第２レバー４１，４２が台本体４から離間するため、そのまま前方へ移動させれば、前側の係止部３８Ａの爪部３９が被係止部８Ａから外れてブラケット２０を取り外すことができる。
このように、回転中心は前後で異なるものの、ブラケット２０の着脱を行う際の第１レバー４１と第２レバー４２との回転操作方向は同じとなっているため、操作はしやすくなる。 On the other hand, when the rear end portion of the first lever 41 and the rear end portion of the second lever 42 are both grasped and rotated upward, as shown in FIG. 9B, the second lever 42 protruding from the slit 46 Rotates first to separate the second stopper 52 from the position close to the first stopper 48, so that the first lever 41 can also be continuously rotated. Then, due to the deviation between the screw 36B, which is the center of rotation of the first lever 41, and the pin 50, which is the center of rotation of the second lever 42, the first stopper 48 and the second stopper 52 remain displaced from each other in the rotation direction. Therefore, interference does not occur. Therefore, as shown in FIG. 9C, the first lever 41 and the second lever 42, which are unlocked from each other, are locked together with the first claw portion 45 and the second claw portion 53. It can be rotated until it comes off. If the rear end of the bracket 20 is lifted upward as it is, the first and second levers 41 and 42 are separated from the base body 4, so if the bracket 20 is moved forward as it is, the claw portion 39 of the locking portion 38A on the front side is released. The bracket 20 can be removed from the locked portion 8A.
As described above, although the center of rotation is different between the front and rear, the rotation operation direction of the first lever 41 and the second lever 42 when attaching and detaching the bracket 20 is the same, so that the operation becomes easier.

ブラケット２０を取り付ける場合はこれと逆に、前側の係止部３８Ａの爪部３９を先に被係止部８Ａに係止させた状態で、そのままブラケット２０の後端を水平に倒す。すると、第１、第２レバー４１，４２が台本体４の後方へ移動し、第１、第２爪部４５，５３が被係止部８Ｂの傾斜面に当接することで第１、第２レバー４１，４２が自動的に回転して第１、第２爪部４５，５３が被係止部８Ｂを乗り越える。その後、コイルバネ４３及びトーションバネ５１の付勢によって第１、第２レバー４１，４２が回転し、第１、第２爪部４５，５３を再び被係止部８Ｂに係止させてブラケット２０を固定することになる。 When the bracket 20 is attached, conversely, the rear end of the bracket 20 is tilted horizontally with the claw portion 39 of the locking portion 38A on the front side locked to the locked portion 8A first. Then, the first and second levers 41 and 42 move to the rear of the base body 4, and the first and second claws 45 and 53 come into contact with the inclined surface of the locked portion 8B, so that the first and second levers 41 and 42 come into contact with each other. The levers 41 and 42 automatically rotate, and the first and second claw portions 45 and 53 get over the locked portion 8B. After that, the first and second levers 41 and 42 are rotated by the urging of the coil spring 43 and the torsion spring 51, and the first and second claw portions 45 and 53 are locked again to the locked portion 8B to lock the bracket 20. It will be fixed.

なお、作業台１に固定される卓上丸鋸盤６０は、図１〜３に示すように、上面に被切断材の載置面を有するベース６１の中央に、ターンテーブル６２を水平回転可能に備え、ターンテーブル６２の後方に立設したアーム６３の上端に、スライドバー６４を前後方向へスライド可能に保持させている。このスライドバー６４の前端に、モータによって回転駆動する縦向きの鋸刃を備えた本体６５を、上下動可能且つ上限位置に付勢して設けたものである。本体６５の上端には上下操作用のハンドル６６が設けられている。ターンテーブル６２の左右に位置するベース６１の右載置部６７と左載置部６８との間には、被切断材をあてがって位置決めするためのガイドフェンス６９が架設されて、両載置部６７，６８の下部には、前後方向に脚部７０，７０がそれぞれ形成されている。この脚部７０の前後両端に、作業台１への固定用の取付孔７１，７１がそれぞれ形成されている。 As shown in FIGS. 1 to 3, the tabletop circular saw machine 60 fixed to the workbench 1 allows the turntable 62 to rotate horizontally in the center of the base 61 having a mounting surface for the material to be cut on the upper surface. The slide bar 64 is slidably held in the front-rear direction at the upper end of the arm 63 erected behind the turntable 62. At the front end of the slide bar 64, a main body 65 having a vertical saw blade that is rotationally driven by a motor is provided so as to be vertically movable and urged to an upper limit position. A handle 66 for vertical operation is provided at the upper end of the main body 65. A guide fence 69 for applying and positioning the material to be cut is erected between the right mounting portion 67 and the left mounting portion 68 of the base 61 located on the left and right sides of the turntable 62, and both mounting portions. Legs 70 and 70 are formed in the lower portions of 67 and 68 in the front-rear direction, respectively. Mounting holes 71 and 71 for fixing to the workbench 1 are formed at both front and rear ends of the leg 70, respectively.

以上の如く構成された作業台１に卓上丸鋸盤６０を固定する際は、台本体４上の左右のブラケット２０，２０を、第１レバー４１，４１のみを握り込んだ状態で、左右の上側台座２１，２１がベース６１の脚部７０，７０の下方に位置するように位置調整を行う。そして、卓上丸鋸盤６０を、左右の上側台座２１，２１間に跨がって載置し、脚部７０，７０の取付孔７１，７１の真下にロックナット２７，２７をそれぞれ位置させる。
ロックナット２７，２７の位置決め後、各脚部７０の上方から取付ボルト２８を、取付孔７１、上側台座２１の上スリット２３の順に貫通させてロックナット２７にねじ込めば、各脚部７０は上側台座２１に結合される。取付ボルト２８は、長めの寸法のものを用意しておけば、脚部７０の厚みが変わっても１種類で対応可能となる。 When fixing the tabletop circular saw machine 60 to the workbench 1 configured as described above, the left and right brackets 20 and 20 on the table body 4 are held in the state where only the first levers 41 and 41 are grasped. The position of the upper pedestals 21 and 21 is adjusted so as to be located below the legs 70 and 70 of the base 61. Then, the tabletop circular saw machine 60 is placed so as to straddle between the left and right upper pedestals 21 and 21, and the lock nuts 27 and 27 are positioned directly below the mounting holes 71 and 71 of the legs 70 and 70, respectively.
After positioning the lock nuts 27 and 27, if the mounting bolts 28 are passed through the mounting holes 71 and the upper slits 23 of the upper pedestal 21 in this order from above the legs 70 and screwed into the lock nuts 27, the legs 70 will be screwed. It is coupled to the upper pedestal 21. If the mounting bolt 28 has a long size, one type can be used even if the thickness of the leg 70 changes.

よって、作業者は、ベース６１及びターンテーブル６２上に被切断材をセットし、ハンドル６６を把持して鋸刃を回転させながら本体６５を下降させることで、被切断材を切断することができる。このとき、長尺の被切断材では、補助バー５，５の支持ローラ１１又は支持板１２とベース６１との間に掛け渡すようにすれば、被切断材の水平状態を維持できて支障なく切断することができる。
そして、被切断材に対して鋸刃を水平回転させて切断を行う角度切りを行う場合は、ターンテーブル６２の前方に突出したグリップ７２を把持してターンテーブル６２を回転させることになるが、この回転角度が大きくなっても、脚部７０の上方には取付ボルト２８が突出していないので、グリップ７２が取付ボルト２８と干渉するおそれはない。 Therefore, the operator can cut the material to be cut by setting the material to be cut on the base 61 and the turntable 62, grasping the handle 66, and lowering the main body 65 while rotating the saw blade. .. At this time, if the long material to be cut is hung between the support rollers 11 or the support plates 12 of the auxiliary bars 5 and 5 and the base 61, the horizontal state of the material to be cut can be maintained without any problem. Can be disconnected.
Then, in the case of performing angle cutting in which the saw blade is horizontally rotated with respect to the material to be cut, the turntable 62 is rotated by grasping the grip 72 protruding in front of the turntable 62. Even if the rotation angle is increased, the mounting bolt 28 does not protrude above the leg 70, so that the grip 72 does not interfere with the mounting bolt 28.

一方、卓上丸鋸盤６０の位置を左右方向で変えたい場合は、左右のブラケット２０，２０において、第１レバー４１，４１のみを握り込めば、そのまま係止力が低下した状態となって任意の位置へスライド可能となる。位置決め後、第１レバー４１，４１の握り込みを解除すれば、各第１爪部４５が再び被係止部８Ｂに係止して当該スライド位置で固定される。
また、卓上丸鋸盤６０を地面等に直置きして使用する場合は、左右のブラケット２０，２０において、第１、第２レバー４１，４２の両方をそれぞれ握り込めば、後側の被係止部８Ｂとの係止が解除されるため、そのまま卓上丸鋸盤６０ごと左右のブラケット２０，２０の後端を持ち上げて手前側に引き寄せれば、前側の被係止部８Ａとの係止も解除されて作業台１から取り外すことができる。よって、ブラケット２０，２０ごと直置きすることができる。上側台座２１のフット２９は、係止部３８Ａ，３８Ｂよりも下方へ突出しているため、４隅のフット２９のみが地面等に当接してベース６１を水平に支持できる。 On the other hand, when it is desired to change the position of the tabletop circular saw 60 in the left-right direction, if only the first levers 41 and 41 are grasped with the left and right brackets 20 and 20, the locking force is lowered as it is and it is arbitrary. It becomes possible to slide to the position of. After positioning, if the grips of the first levers 41 and 41 are released, each of the first claw portions 45 is locked to the locked portion 8B again and fixed at the slide position.
In addition, when the tabletop circular saw machine 60 is used by placing it directly on the ground or the like, if both the first and second levers 41 and 42 are gripped by the left and right brackets 20 and 20, the rear engagement is engaged. Since the locking with the stop portion 8B is released, if the rear ends of the left and right brackets 20 and 20 together with the tabletop circular saw machine 60 are lifted and pulled toward the front side, the locking with the locked portion 8A on the front side is performed. Can also be released and removed from the workbench 1. Therefore, the brackets 20 and 20 can be placed directly. Since the foot 29 of the upper pedestal 21 projects downward from the locking portions 38A and 38B, only the foot 29 at the four corners abuts on the ground or the like to support the base 61 horizontally.

このように、上記形態１のブラケット２０及び作業台１によれば、受け台２上に載置されて卓上丸鋸盤６０が固定される上側台座２１及び下側台座２２（台座）と、受け台２と直交する水平方向で受け台２を両側から挟む位置で下側台座２２に設けられ、受け台２の両側に設けた被係止部８Ａ，８Ｂにそれぞれ係止可能な２つの係止部３８Ａ，３８Ｂと、を含み、係止部３８Ｂは、被係止部８Ｂに対してそれぞれ係脱操作可能な第１レバー４１と第２レバー４２（第１操作部と第２操作部）とからなり、第１レバー４１による被係止部８Ｂからの係止解除操作によって下側台座２２が受け台２に沿って移動可能となると共に、第１レバー４１と第２レバー４２との双方による被係止部８Ｂからの係止解除操作によって下側台座２２が受け台２から取り外し可能となり、第１レバー４１と第２レバー４２とのそれぞれの係脱操作方向は同じとなっている。よって、受け台２上での位置調整や着脱作業がスムーズに行えて作業性に優れたものとなる。 As described above, according to the bracket 20 and the work table 1 of the above-described first form, the upper pedestal 21 and the lower pedestal 22 (pedestal) which are placed on the pedestal 2 and to which the tabletop round saw machine 60 is fixed and the receiver Two locks provided on the lower pedestal 22 at positions sandwiching the pedestal 2 from both sides in a horizontal direction orthogonal to the pedestal 2 and lockable to the locked portions 8A and 8B provided on both sides of the pedestal 2, respectively. The locking portion 38B includes the portions 38A and 38B, and the locking portion 38B includes a first lever 41 and a second lever 42 (first operating portion and second operating portion) that can be engaged with and disengaged from the locked portion 8B, respectively. The lower pedestal 22 can be moved along the pedestal 2 by the unlocking operation from the locked portion 8B by the first lever 41, and both the first lever 41 and the second lever 42 are used. The lower pedestal 22 can be removed from the pedestal 2 by the unlocking operation from the locked portion 8B, and the engaging / disengaging operation directions of the first lever 41 and the second lever 42 are the same. Therefore, the position adjustment and the attachment / detachment work on the cradle 2 can be smoothly performed, and the workability is excellent.

特にここでは、第１操作部と第２操作部とを、下側台座２２へ端部がそれぞれ回転可能に連結された第１レバー４１と第２レバー４２として、係脱操作方向となる回転操作方向を同じとしているので、同じ方向への回転操作（握り込み）によって被係止部８Ｂとの係止解除操作がスムーズに行える。
また、第１レバー４１と第２レバー４２とのそれぞれの回転中心が前後方向でずれて配置されて、第１レバー４１と第２レバー４２とには、第１レバー４１のみの係止解除操作の際に互いに当接して互いの回転を規制する第１ストッパ４８と第２ストッパ５２とが設けられているので、第１レバー４１の単独操作の場合の回転規制と両レバー４１，４２の同時操作の場合の規制解除とが少ない部品点数で確実に行える。
さらに、第２レバー４２は、第１レバー４１に設けた前後方向のスリット４６内に収容されているので、レバーを２つ設けても省スペースとなると共に、第１、第２レバー４１，４２の同時握り込みが簡単に行え、操作性も良好となる。 In particular, here, the first operation unit and the second operation unit are designated as the first lever 41 and the second lever 42, whose ends are rotatably connected to the lower pedestal 22, respectively, and the rotation operation is in the engagement / disengagement operation direction. Since the directions are the same, the unlocking operation with the locked portion 8B can be smoothly performed by the rotation operation (grasping) in the same direction.
Further, the rotation centers of the first lever 41 and the second lever 42 are arranged so as to be offset in the front-rear direction, and the first lever 41 and the second lever 42 are unlocked only by the first lever 41. Since the first stopper 48 and the second stopper 52 that come into contact with each other and regulate the rotation of each other are provided at the time of the above, the rotation regulation in the case of the independent operation of the first lever 41 and the simultaneous rotation of both levers 41 and 42 are provided. Deregulation in the case of operation can be reliably performed with a small number of parts.
Further, since the second lever 42 is housed in the slit 46 in the front-rear direction provided in the first lever 41, space can be saved even if two levers are provided, and the first and second levers 41 and 42 are provided. Can be easily grasped at the same time, and operability is also good.

そして、上記形態１のブラケット２０及び作業台１によれば、受け台２上に載置されて卓上丸鋸盤６０が固定される上側台座２１及び下側台座２２（台座）と、受け台２と直交する水平方向で受け台２を両側から挟む位置で下側台座２２に設けられ、受け台２の両側に設けた被係止部８Ａ，８Ｂにそれぞれ係止可能な２つの係止部３８Ａ，３８Ｂと、を含み、係止部３８Ｂは、被係止部８Ｂに対して係脱操作可能な第１レバー４１（操作部）と、第１レバー４１の移動範囲を規制する第２レバー４２（規制部）とを有し、第１レバー４１と第２レバー４２とを同じ方向に移動させることにより、下側台座２２が受け台２から取り外し可能となっている。よって、受け台２上での位置調整や着脱作業がスムーズに行えて作業性に優れたものとなる。 Then, according to the bracket 20 and the workbench 1 of the first embodiment, the upper pedestal 21 and the lower pedestal 22 (pedestal) mounted on the pedestal 2 and fixed to the tabletop circular saw machine 60, and the pedestal 2 Two locking portions 38A that are provided on the lower pedestal 22 at positions that sandwich the pedestal 2 from both sides in the horizontal direction orthogonal to the pedestal 2 and can be locked to the locked portions 8A and 8B provided on both sides of the pedestal 2, respectively. , 38B, and the locking portion 38B includes a first lever 41 (operating portion) that can be engaged with and disengaged from the locked portion 8B, and a second lever 42 that regulates the movement range of the first lever 41. The lower pedestal 22 can be removed from the pedestal 2 by having the (regulating portion) and moving the first lever 41 and the second lever 42 in the same direction. Therefore, the position adjustment and the attachment / detachment work on the cradle 2 can be smoothly performed, and the workability is excellent.

なお、上記形態１では、第１レバーのスリットに第２レバーを収容しているが、第１レバーの側面に凹部を設けて第２レバーを凹部内に収容してもよいし、凹部を設けずに第１レバーと第２レバーとを左右方向に隣接配置することもできる。これらの場合、互いに当接するストッパは互いに隣接する側面側にのみ設けられる。各レバーの長さや爪部の形状等も適宜変更で、複数の部品を組み合わせてレバーを形成してもよい。
また、上記形態１では、前側の係止部をフック体、後側の係止部を２つのレバーとしているが、前後逆としてもよいし、前後両側を２つのレバーとしてもよい。 In the above mode 1, the second lever is housed in the slit of the first lever, but a recess may be provided on the side surface of the first lever to accommodate the second lever in the recess, or the recess may be provided. It is also possible to arrange the first lever and the second lever adjacent to each other in the left-right direction without using the lever. In these cases, the stoppers that come into contact with each other are provided only on the side surfaces adjacent to each other. The length of each lever, the shape of the claw portion, and the like may be appropriately changed to form a lever by combining a plurality of parts.
Further, in the above-described first embodiment, the front locking portion is a hook body and the rear locking portion is two levers, but the front and rear locking portions may be reversed or the front and rear both sides may be two levers.

一方、ブラケットの台座は、上記形態１では電動工具が固定される上側台座と、受け台に固定される下側台座とに分割しているが、１つの台座で上面に電動工具を、下面に係止部（操作部及び規制部）をそれぞれ設けることもできる。電動工具の固定構造も上記形態１に限定されない。
そして、作業台の構造も、補助バーの一方又は両方を省略したり、脚を折り畳みでなく伸縮式としたり、脚をリンク構造にしたり等、適宜変更可能である。固定する電動工具も、卓上丸鋸盤以外にカッタ等の他の種類であっても差し支えない。 On the other hand, the pedestal of the bracket is divided into an upper pedestal to which the power tool is fixed and a lower pedestal to be fixed to the pedestal in the above mode 1, but one pedestal has the power tool on the upper surface and the lower surface. Locking portions (operating portion and regulating portion) may be provided respectively. The fixing structure of the power tool is not limited to the above-described first form.
The structure of the workbench can also be changed as appropriate, such as omitting one or both of the auxiliary bars, making the legs telescopic instead of folding, and making the legs a link structure. The power tool to be fixed may be another type such as a cutter other than the tabletop circular saw.

［形態２］
次に、ブラケットのロックがより確実に行える他の形態を以下に説明する。但し、上記形態１と同じ構成部には同じ符号を付して重複する説明は省略し、異なる構成部を主に説明する。
図１０に示す第１レバー４１では、上記形態１の第１ストッパが設けられていない。第１レバー４１において、凹部４７，４７側へ突出する第１爪部４５の上面には、回転規制位置で前後方向に延びる平面部４５ａ，４５ａが、スリット４６を挟んで左右に形成されている。平面部４５ａは、図１２（Ａ）に示すように、被係止部８Ｂへの係止状態では、第２レバー４２の第２ストッパ５２よりも下方で且つ前方に位置している。平面部４５ａの前後端がネジ３６Ｂを中心として回転する際の一点鎖線で示す円弧軌跡Ｌ１は、第２ストッパ５２の下端よりも後方下側を通過するようになっている。第１爪部４５の下方には、被係止部８Ｂへの係止状態で前方下向きに突出する第１角部４９が形成されている。
図１１に示す第２レバー４２では、被係止部８Ｂへの係止状態で下向きに突出する第２角部５４が形成されている。 [Form 2]
Next, another form in which the bracket can be locked more reliably will be described below. However, the same components as in the first embodiment are designated by the same reference numerals, duplicated description will be omitted, and different components will be mainly described.
The first lever 41 shown in FIG. 10 is not provided with the first stopper of the first aspect. In the first lever 41, flat surfaces 45a and 45a extending in the front-rear direction at the rotation restriction position are formed on the upper surface of the first claw portion 45 protruding toward the recesses 47 and 47 on the left and right sides of the slit 46. .. As shown in FIG. 12A, the flat surface portion 45a is located below and in front of the second stopper 52 of the second lever 42 in the locked state with the locked portion 8B. The arc locus L1 indicated by the alternate long and short dash line when the front and rear ends of the flat surface portion 45a rotate around the screw 36B is adapted to pass behind and below the lower end of the second stopper 52. Below the first claw portion 45, a first corner portion 49 that projects forward and downward in a locked state with the locked portion 8B is formed.
In the second lever 42 shown in FIG. 11, a second corner portion 54 that protrudes downward in a locked state with the locked portion 8B is formed.

図１２（Ａ）の係止状態から第１レバー４１のみを上側へ回転させる。すると、図１２（Ｂ）に示すように、平面部４５ａが円弧軌跡Ｌ１に沿って後方へ移動し、第２ストッパ５２の下端に当接する。この当接時点で平面部４５ａは、前下がりの傾斜姿勢となり、平面部４５ａの後端は、第２ストッパ５２の下端の後方でやや上側に位置する。よって、第１レバー４１の回転操作の後に第２レバー４２を上側へ回転させようとすると、第２ストッパ５２の後方への移動が平面部４５ａに阻止される。すなわち、第２レバー４２を回転させることができなくなる。
この状態で第１レバー４１のみを回転させようとすると、傾斜する平面部４５ａの案内により、第２ストッパ５２が、一点鎖線で示すピン５０を中心とした回転軌跡Ｌ２に沿って前方（被係止部８Ｂへの係止側）へ回転付勢される。このくさびの作用により、第１レバー４１との間の摩擦によって第２レバー４２が第１レバー４１と共に回転しようとする動きが抑えられる。すなわち、第２爪部５３の被係止部８Ｂへの係止状態（ロック状態）が維持される。第１レバー４１も、ロック状態の第２レバー４２の第２ストッパ５２が平面部４５ａに当接するため、それ以上の回転操作が不能となる。 Only the first lever 41 is rotated upward from the locked state shown in FIG. 12 (A). Then, as shown in FIG. 12B, the flat surface portion 45a moves rearward along the arc locus L1 and comes into contact with the lower end of the second stopper 52. At the time of this contact, the flat surface portion 45a is in an inclined posture downward, and the rear end of the flat surface portion 45a is located slightly above the lower end of the second stopper 52. Therefore, if the second lever 42 is to be rotated upward after the rotation operation of the first lever 41, the rearward movement of the second stopper 52 is blocked by the flat surface portion 45a. That is, the second lever 42 cannot be rotated.
When only the first lever 41 is to be rotated in this state, the second stopper 52 is forward (engaged) along the rotation locus L2 centered on the pin 50 indicated by the alternate long and short dash line by the guidance of the inclined flat surface portion 45a. Rotationally urged to the locking side to the stop 8B). Due to the action of this wedge, the movement of the second lever 42 trying to rotate together with the first lever 41 due to friction with the first lever 41 is suppressed. That is, the locked state (locked state) of the second claw portion 53 with respect to the locked portion 8B is maintained. As for the first lever 41, since the second stopper 52 of the second lever 42 in the locked state comes into contact with the flat surface portion 45a, further rotation operation becomes impossible.

一方、第１レバー４１の後端部と第２レバー４２の後端部とを共に握り込んで上側へ回転させる。すると、図１２（Ｃ）に示すように、スリット４６から突出した第２レバー４２が先に回転して第２ストッパ５２を平面部４５ａの回転軌跡Ｌ１の外側へ移動させる。これにより、平面部４５ａが第２ストッパ５２に当接しなくなるため、第１レバー４１も続いて回転させることができる。よって、第１レバー４１と第２レバー４２とを、第１爪部４５と第２爪部５３とが共に被係止部８Ｂから外れるまで回転させることができる。
そして、ブラケット２０の後端を上側へ持ち上げれば、第１、第２レバー４１，４２が台本体４から離間するため、そのまま前方へ移動させれば、前側の係止部３８Ａの爪部３９が被係止部８Ａから外れてブラケット２０を取り外すことができる。 On the other hand, the rear end portion of the first lever 41 and the rear end portion of the second lever 42 are both grasped and rotated upward. Then, as shown in FIG. 12C, the second lever 42 protruding from the slit 46 rotates first to move the second stopper 52 to the outside of the rotation locus L1 of the flat surface portion 45a. As a result, the flat surface portion 45a does not come into contact with the second stopper 52, so that the first lever 41 can also be continuously rotated. Therefore, the first lever 41 and the second lever 42 can be rotated until both the first claw portion 45 and the second claw portion 53 are disengaged from the locked portion 8B.
Then, if the rear end of the bracket 20 is lifted upward, the first and second levers 41 and 42 are separated from the base body 4, so if the bracket 20 is moved forward as it is, the claw portion 39 of the locking portion 38A on the front side is used. Can be removed from the locked portion 8A and the bracket 20 can be removed.

なお、ブラケット２０を取り外した状態で、トーションバネ５１によって下向きに回転付勢される第２レバー４２は、図１３に示すように、第２ストッパ５２が設けられる前面が、ネジ３６Ｂが貫通する第１レバー４１の支点部５５に当接する。この当接位置で第２レバー４２は回転規制される。
ブラケット２０を取り付ける場合は、前側の係止部３８Ａの爪部３９を先に被係止部８Ａに係止させた状態で、そのままブラケット２０の後端を水平に倒す。すると、第１レバー４１は、第１爪部４５の第１角部４９が被係止部８Ｂの傾斜面に当接することで、コイルバネ４３の付勢に抗して上側へ自動的に回転する。このとき、第２レバー４２でも、ブラケット２０の倒伏に連れて第２角部５４が被係止部８Ｂの傾斜面に当接する。
第１レバー４１の回転に伴い、支点部５５が第２ストッパ５２に当接することで、第２レバー４２もトーションバネ５１の付勢に抗して上側へ回転する。よって、第１、第２爪部４５，５３が被係止部８Ｂを乗り越える。その後、図１２（Ａ）のように、コイルバネ４３及びトーションバネ５１の付勢によって第１、第２レバー４１，４２が係止方向へ回転し、第１、第２爪部４５，５３を再び被係止部８Ｂに係止させてブラケット２０を固定することになる。 As shown in FIG. 13, the second lever 42, which is rotationally urged downward by the torsion spring 51 with the bracket 20 removed, has a second lever 42 through which the screw 36B penetrates the front surface where the second stopper 52 is provided. 1 It comes into contact with the fulcrum portion 55 of the lever 41. The rotation of the second lever 42 is restricted at this contact position.
When attaching the bracket 20, the rear end of the bracket 20 is tilted horizontally with the claw portion 39 of the locking portion 38A on the front side first locked to the locked portion 8A. Then, the first lever 41 automatically rotates upward against the urging of the coil spring 43 when the first corner portion 49 of the first claw portion 45 comes into contact with the inclined surface of the locked portion 8B. .. At this time, also in the second lever 42, the second corner portion 54 comes into contact with the inclined surface of the locked portion 8B as the bracket 20 falls down.
As the first lever 41 rotates, the fulcrum portion 55 comes into contact with the second stopper 52, so that the second lever 42 also rotates upward against the urging of the torsion spring 51. Therefore, the first and second claw portions 45 and 53 get over the locked portion 8B. After that, as shown in FIG. 12 (A), the first and second levers 41 and 42 rotate in the locking direction due to the urging of the coil spring 43 and the torsion spring 51, and the first and second claws 45 and 53 are pressed again. The bracket 20 is fixed by locking the locked portion 8B.

このように、上記形態２のブラケット２０及び作業台１でも、第１操作部（第１レバー４１）と第２操作部（第２レバー４２）との双方による被係止部８Ｂからの係止解除操作によって下側台座２２が受け台２から取り外し可能となり、第１レバー４１と第２レバー４２とのそれぞれの係脱操作方向は同じとなっている。そして、第１レバー４１を単独で係止解除操作すると、第２レバー４２は係止解除操作が不能となっている。
この構成により、受け台２上での着脱作業がスムーズに行えて作業性に優れると共に、第２レバー４２による確実なロックも可能となる。 As described above, even in the bracket 20 and the workbench 1 of the second embodiment, the first operating portion (first lever 41) and the second operating portion (second lever 42) are both locked from the locked portion 8B. The lower pedestal 22 can be removed from the pedestal 2 by the release operation, and the engagement / disengagement operation directions of the first lever 41 and the second lever 42 are the same. Then, when the first lever 41 is independently unlocked, the second lever 42 cannot be unlocked.
With this configuration, the attachment / detachment work on the cradle 2 can be smoothly performed, the workability is excellent, and the second lever 42 can be securely locked.

特に、第１レバー４１の第１爪部４５には、第１レバー４１の単独での係止解除操作の際に第２レバー４２に当接する平面部４５ａ（当接部）が設けられ、平面部４５ａへの当接によって第２レバー４２の係止解除操作が不能となっている。よって、第１レバー４１を利用した第２レバー４２のロックが簡単に行える。
また、平面部４５ａは、第１レバー４１の回転に伴って第２レバー４２を被係止部８Ｂへの係止方向へ回転付勢する。よって、より確実なロックが行える。
また、当接部は、第１レバー４１の回転に伴って傾斜姿勢となって第２レバー４２を係止方向へ回転付勢する平面部４５ａとなっている。よって、当接部が簡単に形成可能となる。 In particular, the first claw portion 45 of the first lever 41 is provided with a flat surface portion 45a (contact portion) that abuts on the second lever 42 when the first lever 41 is independently unlocked. The contact with the portion 45a makes it impossible to unlock the second lever 42. Therefore, the second lever 42 can be easily locked by using the first lever 41.
Further, the flat surface portion 45a rotationally urges the second lever 42 in the locking direction with respect to the locked portion 8B as the first lever 41 rotates. Therefore, more reliable locking can be performed.
Further, the contact portion is a flat surface portion 45a that is tilted as the first lever 41 rotates and urges the second lever 42 to rotate in the locking direction. Therefore, the contact portion can be easily formed.

なお、上記形態２においても、上記形態１と同様の変更が可能である。例えば、第１レバーの側面に凹部を設けて第２レバーを凹部内に収容する変更と、凹部を設けずに第１レバーと第２レバーとを左右方向に隣接配置する変更とが可能である。これらの変更においては、平面部と第２ストッパ部とは互いに隣接する側面側にのみ設けることができる。
当接部は、平面部に限らず、曲面部（凹曲面でも凸曲面でもよい）であってもよい。 It should be noted that the same changes as in the first form can be made in the second form. For example, it is possible to change the side surface of the first lever to have a recess to accommodate the second lever in the recess, or to arrange the first lever and the second lever adjacent to each other in the left-right direction without providing the recess. .. In these changes, the flat surface portion and the second stopper portion can be provided only on the side surface side adjacent to each other.
The contact portion is not limited to the flat surface portion, and may be a curved surface portion (a concave curved surface or a convex curved surface).
