Abstract

PROBLEM TO BE SOLVED: To enable setting easily even in a small-sized model by a method in which a lower limit change-over member is moved to a lower limit regulating position with which a lower limit regulating member contacts or a lower limit releasing position through which it passes without contacting so as to change over the validity and invalidity of a stopper. SOLUTION: When a lower limit change-over member 25 is positioned at a lower limit release position, a positioning projection is inserted into the first recession. By this operation, the member 25 is position-held at a lower limit regulating position. In a state in which the member 25 is held at the lower limit regulating position, since the member 25 is not positioned downward from a lower limit regulating bolt 22, when a circular sawing machine main body 4 is moved downward, the bolt 22 passes by the side of the member 25 without colliding with it. In this way, there is no need to secure a space for moving an arm as before in the base end part 4a of the saw main body 4 so that a stopper 20 can be easily applied even to a sized circular sawing machine.

【発明の実施の形態】次に、本発明の実施形態を図1〜 DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention FIG. 1
図8に基づいて説明する。 It will be described with reference to FIG. 図1は本実施形態に係るストッパ装置20を備えた丸鋸盤1の全体を示している。 Figure 1 shows the entire circular saw 1 having a stopper device 20 according to the present embodiment. 図中2は切断材料を載置するためのテーブルであって、ベース3に回転可能に支持されている。 Figure 2 is a table for placing a cutting material, and is rotatably supported on the base 3. このテーブル2の下面にはスライドバー5が軸受6を介して軸方向(図示左右方向)に移動可能に支持されている。 Slide bar 5 is movably supported in the axial direction (lateral direction) via the bearing 6 on the lower surface of the table 2. このスライドバー5の後端部(図示左端部)に左右傾動機構7が取付けられ、この左右傾動機構7のアーム8の先端に丸鋸本体4が傾動支点9を介して上下方向に傾動可能に支持されている。 Laterally tilting mechanism 7 is attached to the rear end of the slide bar 5 (shown left end), the circular saw main body 4 to the distal end of the arm 8 of the laterally tilting mechanism 7 is tiltable in the vertical direction through the tilting fulcrum 9 It is supported.

【0009】本実施形態は丸鋸本体4の下限位置を規制するためのストッパ装置20に特徴を有するのであり、 [0009] The present embodiments are to have a characteristic the stopper device 20 for regulating the lower limit position of the circular saw main body 4,
テーブル2、丸鋸本体4および左右傾動機構7等のその他の構成については特に変更を要しないので説明を省略する。 Table 2, since no particular required changes for other configurations such as the circular saw main body 4 and laterally tilting mechanism 7 will not be described.

【0010】さて、本実施形態のストッパ装置20の詳細が図2以下に示されている。 [0010] Now, details of the stopper device 20 of the present embodiment is shown in the following Figure 2. 丸鋸本体4の基端部4a Proximal end 4a of the circular saw main body 4
の側面には、支持片21が側方へ張出し状に形成され、 The side surface of the support piece 21 is formed in a flared shape to the side,
この支持片21には頭部につまみ22aを有する下限規制ボルト22と、当該丸鋸本体4の最下降限を規制するための固定ボルト23が取付けられている。 The lower limit regulating bolt 22 having 22a knob head to the support piece 21, fixing bolts 23 for regulating the lowermost limit of the circular saw main body 4 is attached.

【0011】下限規制ボルト22は回転させることによりその先端を上下に進退させることができ、これにより丸鋸本体4の下降限を一定の範囲で任意に設定することができる。 [0011] The lower limit restricting bolt 22 is able to advance and retract the tip up and down by rotating, thereby it is possible to arbitrarily set the lowering limit of the circular saw main body 4 at a certain range. この下限規制ボルト22が特許請求の範囲に記載した下限規制部材の一実施形態に相当する。 The lower regulating bolt 22 corresponds to an embodiment of the lower regulating member as set forth in the appended claims. なお、 It should be noted that,
固定ボルト23を回転させることにより丸鋸本体4の最下降限を変更することができるが、この最下降限は前記したように鋸刃4bと刃口板との位置関係により決定されるものであり、通常の使用状態では固定的な下限として設定される。 Although it is possible to change the lowermost limit of the circular saw main body 4 by rotating the fixing bolt 23, the lowermost limit is intended to be determined by the positional relationship between the saw blade 4b and the blade edge plate as described above There, in a normal use state is set as a fixed limit.

【0012】次に、左右傾動機構7のアーム8の先端には、台座部24が先方へ張出し状に設けられており、この台座部24の上面24aには板状の下限切換え部材2 [0012] Next, lateral tilt to the distal end of the arm 8 of the rotation mechanism 7, and the pedestal portion 24 is provided in a projecting form to the other party, lower switching member second plate of the upper surface 24a of the base portion 24
5が取付けられている。 5 is attached. 図4に示すようにこの下限切換え部材25は支軸26を介して横方向(当該下限切換え部材25の面方向)へ一定の範囲で回動可能に支持されている。 4 The lower switching member 25 as shown in is rotatably supported to a certain extent in the transverse direction (surface direction of the lower switching element 25) via a support shaft 26. 図4(A)は下限切換え部材25を下限解除位置に位置させた状態を示し、図4(B)は下限切換え部材25を下限規制位置に位置させた状態を示している。 4 (A) shows a state in which to position the lower switching member 25 to the lower release position, FIG. 4 (B) shows a state in which to position the lower switching member 25 to the lower limit restricting position.
下限規制位置とは、丸鋸本体4が一定位置まで下動すると上記下限規制ボルト22が突き当たる位置を言い、その結果当該ストッパ装置20により丸鋸本体4の下限が規制される位置を言う。 The lower limit restricting position, when the circular saw main body 4 is moved downward to a predetermined position means a position where the lower limit regulating bolt 22 abuts, it refers to the result location lower limit of the circular saw main body 4 is restricted by the stopper device 20. また、下限解除位置とは、丸鋸本体4が下動しても下限規制ボルト22が突き当たらない位置を言い、その結果当該ストッパ装置20によっては丸鋸本体4の下限が規制されず、丸鋸本体4の下限が固定ボルト23により最下降限に規制されることとなる位置を言う。 Further, the lower limit release position refers to a position where the circular saw main body 4 is not impinge the lower regulating bolt 22 also moves downward, without being restricted lower limit of the circular saw main body 4 by a result the stopper unit 20, a round the lower limit of the saw body 4 refers to a position that would be restricted to the lowermost limit by the fixing bolts 23.

【0013】台座部24の上面24aのほぼ中央には円形の突起部24bが一体に形成されている。 [0013] substantially at the center of the upper surface 24a of the base portion 24 circular protruding portion 24b are integrally formed. この突起部24bは、上記下限切換え部材25の板厚に相当する高さで上方(図4において手前側)へ突き出している。 The protrusion 24b is projected upward (front side in FIG. 4) at a height corresponding to the thickness of the lower switching member 25. この突起部24bには、当該ストッパ装置20を無効にした状態で、丸鋸本体4を下動させたときに固定ボルト2 The projections 24b, while disabling the stopper device 20, the fixing bolt 2 when moved downward circular saw main body 4
3が突き当てられ、これにより丸鋸本体4の最下降限が規制される。 3 is abutted, thereby lowermost limit of the circular saw main body 4 is restricted. 従って、この突起部24bは、図9におけるストッパ部79に相当する。 Accordingly, the protrusion 24b corresponds to the stopper portion 79 in FIG.

【0014】同じく台座部24の上面24aであって、 [0014] Also on the upper surface 24a of the base portion 24,
上記突起部24bよりも先端側(図示右側)には、2個の凹部24c,24dが形成されている。 The distal end side than the protruding portion 24b (the right side in the figure), the two recesses 24c, 24d are formed. 図示上側の第1凹部24cは、上面24aの図示上端縁から一定の深さ(紙面直交する方向の深さ)で切込み形成され、図示下側の第2凹部24dは同じ深さで円形に形成されている。 The first recess 24c of the upper side in the figure is cut formed in the illustrated upper edge from a predetermined depth of the upper surface 24a (the direction of the depth of the paper orthogonal), the second recess 24d illustrated lower formed in a circular shape at the same depth It is.

【0015】一方、下限切換え部材25には、当該下限切換え部材25を下限解除位置に位置させる時に上記突起部24bを逃がすための逃がし凹部25aと、第1凹部24c又は第2凹部24dに嵌まり込んで、当該下限切換え部材25を下限解除位置又は下限規制位置に位置保持するための位置決め突起25bが形成されている。 Meanwhile, the lower limit switching member 25 includes a relief recess 25a for releasing the protrusion 24b when to position the lower switching member 25 to the lower limit release position, it fits into the first recess 24c or the second recess 24d crowded in, positioning projection 25b for positioning holding the lower switching member 25 to the lower release position or the lower limit restricting position is formed.
逃がし凹部25aは、突起部24bを挿入可能な径(幅)で図示上端縁から切込み形成されている。 Escape recess 25a is cut formed from the illustrated upper edge with insertable projections 24b diameter (width). 位置決め突起25bは、当該下限切換え部材25の上面を凹ませて局所的に板厚方向に変形させることにより形成したもので、台座部24側(下面側)にわずかに突き出している。 Positioning projection 25b is recessed to the upper surface of the lower switching member 25 which was formed by locally deformed in the thickness direction, it is slightly protruding on the base portion 24 side (lower surface side).

【0016】このように構成した本実施形態のストッパ装置20によれば、図4(A)に示すように当該下限切換え部材25を下限解除位置に位置させると、この位置決め突起25bが第1凹部24cに嵌まり込み、これにより当該下限切換え部材25が下限解除位置に位置保持される。 According to the stopper device 20 of the present embodiment configured as described above, when the lower limit switching member 25 is positioned at the lower limit release position as shown in FIG. 4 (A), the positioning projection 25b is first recess Mari included fitted to 24c, thereby the lower switching member 25 is held in place in the lower release position. 下限切換え部材25を下限解除位置に保持した状態では、下限規制ボルト22の下方には下限切換え部材25が位置していないので、図6に示すように丸鋸本体4を下動させた時、下限規制ボルト22は下限切換え部材25に突き当たることなくその側方を通過する。 When in the state of holding the lower switching member 25 to the lower release position, below the lower limit regulating bolt 22 because lower switching member 25 is not located, which is moved downward to the circular saw main body 4 as shown in FIG. 6, lower regulating bolt 22 passes through the side without impinging on lower switching member 25. なお、この場合には図示するように固定ボルト23が突起部24bに突き当るので、当該丸鋸本体4の下降限は最下降限に規制される。 The fixed bolt 23 as illustrated in this case because abuts the protrusion 24b, descent limit of the circular saw main body 4 is restricted to the lowermost limit.

【0017】一方、図4(B)に示すように下限切換え部材25を下限規制位置に位置させると、この位置決め突起25bが第2凹部24dに嵌まり込み、これにより当該下限切換え部材25の下限規制位置が保持される。 Meanwhile, when the lower limit switching member 25 is positioned at the lower limit restriction position as shown in FIG. 4 (B), the positioning projection 25b is included fits into the second recess 24d, thereby the lower limit of the lower switching member 25 regulatory position is held.
下限切換え部材25を下限規制位置に位置させた状態では、下限規制ボルト22の下方に下限切換え部材25が位置しているので、図3に示すように丸鋸本体4を一定位置まで下動させると、下限規制ボルト22が下限切換え部材25に突き当たり、これにより丸鋸本体4の下降限が最下降限よりも上方に規制される。 In a state in which the lower limit switching member 25 is positioned at the lower limit restricting position, the lower the switching member 25 below the lower limit regulating bolt 22 is positioned, is moved downward the circular saw main body 4 to a predetermined position as shown in FIG. 3 When the lower limit regulating bolt 22 abuts against the lower switching member 25, thereby lowering limit of the circular saw main body 4 is restricted to above the lowermost limit. なお、この場合、図示するように固定ボルト23は突起部24bの上面従って下限切換え部材25の上面から浮いている。 In this case, the fixing bolt 23 as shown is floated from the upper surface thus the upper surface of the lower switching element 25 of the protrusion 24b.

【0018】下限切換え部材25を下限解除位置から下限規制位置へ、あるいはその逆に位置変更を行うには、 [0018] the lower limit restricting position the lower switching member 25 from the lower limit release position, or to do repositioning vice versa,
その先端を指で押して一定角度だけ回動させてやればよい。 The tip may do it by only rotating a certain angle by pressing with a finger. この回動操作力により、下限切換え部材25は、台座部24から浮き上がる方向にわずかに撓みつつ、位置決め突起25bが第1凹部24c又は第2凹部24dから抜け出ることにより回動可能となる。 By this rotation operation force, lower switching member 25, while slightly bending in the direction lifted from the base unit 24, the positioning projection 25b is rotatable by being withdrawn from the first recess 24c or the second recess 24d. 位置変更後、位置決め突起25bが再び第1又は第2凹部24c,24 After repositioning, the positioning projection 25b is again the first or second recesses 24c, 24
dに嵌まり込むことにより、当該下限切換え部材25が位置保持される。 By fitted into d, the lower the switching member 25 is held in place.

【0019】このように、本実施形態のストッパ装置2 [0019] Thus, the stopper device of the present embodiment 2
0によれば、丸鋸本体4に設けた下限規制ボルト22を移動させるのではなく、丸鋸本体4を支持するテーブル側(アーム8)に設けた下限切換え部材25を移動させることにより、当該ストッパ装置20の有効、無効を切り換える構成であるので、丸鋸本体4の基端部4aに従来のようなアーム85を移動させるためのスペースを確保する必要はなく、従って小型の丸鋸盤であっても当該ストッパ装置20を容易に適用することができる。 According to 0, instead of moving the lower limit restricting bolt 22 provided on the circular saw main body 4, by moving the lower switching member 25 provided on the table side (arm 8) for supporting the circular saw main body 4, the enable the stopper device 20, since it is configured to switch the disabled, there is no need to secure a space for moving the arm 85 as in the prior art to the base end portion 4a of the circular saw main body 4, thus a small circular saw machine the stopper device 20 even can be readily applied.

【0020】以上説明した実施形態には、種々変更を加えることができる。 [0020] The embodiment described above may be modified in various ways. 例えば、下限切換え部材25は支軸26を中心にして回動する構成を例示したが、面方向(例えば図4において左右方向)にスライドさせることにより下限規制位置と下限解除位置の切換えを行う構成としてもよい。 For example, the lower limit switching member 25 is illustrated a configuration which rotates around the support shaft 26, a configuration for switching the lower regulation position and the lower limit release position by sliding in the (horizontal direction in example 4) surface direction it may be.

【0021】また、下限規制部材は、例示した下限規制ボルト22ではなくピンあるいはその他の当接手段を用いてもよく、しかもこの下限規制部材は、必ずしも例示したように支持片21に対して上下に進退可能である必要はない。 Further, the lower limit regulating member may be used exemplified lower regulating bolt pin or other abutment means rather than 22, yet the lower regulating member is not necessarily vertical to the support piece 21 as illustrated It need not be movable back and forth to.

【0022】さらに、下限切換え部材側に下限を調整するためのボルトを取付け、このボルトが下限規制位置と下限解除位置との間を移動可能な構成としてもよい。 Furthermore, the mounting bolts for adjusting the lower limit to the lower limit switching member side may be movable structure between the bolt and the lower regulation position and the lower limit release position. この場合、丸鋸本体側の下限規制部材はこのボルトが下限規制位置に位置するときにこのボルトに当接する当接片を張出し形成しておく構成とすればよい。 In this case, the lower limit regulating member of the circular saw main body side may be configured to keep overhanging form an abutment piece which abuts on the bolt when the bolt is positioned at the lower regulation position.
