また固定締付部２から見て連結片４より遠方のボルト６
の周囲にはつる巻きばね１４をＵ字形に巻き掛け、その
両端を開穿８の底部８ａにビス１４ａで固定しである。Also, bolts 6 located further away from the connecting piece 4 when viewed from the fixed tightening part 2
A helical spring 14 is wound around it in a U-shape, and its both ends are fixed to the bottom 8a of the opening 8 with screws 14a.

従って図においてボルト６をねじ込んで行くと、ボルト
６の先端は開穿８の内面を押し、その反力は連結片４及
び脚１０を介してピン１１の係合した横溝７によって支
持され、その反対に可動締付部３は基台１上を滑って固
定締付部２の方に押される。Therefore, as shown in the figure, when the bolt 6 is screwed in, the tip of the bolt 6 pushes against the inner surface of the cutout 8, and the reaction force is supported by the lateral groove 7 engaged with the pin 11 via the connecting piece 4 and the leg 10. Conversely, the movable clamping part 3 slides on the base 1 and is pushed towards the fixed clamping part 2.

図から明らかなように、脚１０のピン１１を一つの横溝
７に係合させた位置では、脚１０と貫通孔９との間の締
付方向クリアランス分だけ、可動締付部３の可動範囲が
ある。As is clear from the figure, in the position where the pin 11 of the leg 10 is engaged with one horizontal groove 7, the movable range of the movable tightening part 3 is equal to the clearance in the tightening direction between the leg 10 and the through hole 9. There is.

この範囲はピン１１を両隣りの倒れか一方の横溝７に掛
は換えた場合における可動締付部３の可動範囲と充分型
なるように設けである。This range is set so as to be sufficiently similar to the movable range of the movable tightening portion 3 when the pins 11 are bent on both sides or hooked on one of the lateral grooves 7.

連結片４はその底部を可動締付部３の開穿８の底部８ａ
と密着状態ではその位置を動かすことができない。The connecting piece 4 has its bottom connected to the bottom 8a of the opening 8 of the movable tightening part 3.
If the object is in close contact with the object, its position cannot be moved.

それで、連結片４に対して可動締付部３を固定締付部２
の方に許される限り前進させ、ボルト６の先端を連結片
４内に引込めると、ピン１１の係合する横溝７を中心と
して連結片４を上方に廻して持ち上げることができる。Therefore, the movable clamping part 3 is fixed to the connecting piece 4 by the clamping part 2.
When the bolt 6 is moved forward as far as allowed and the tip of the bolt 6 is retracted into the connecting piece 4, the connecting piece 4 can be rotated upward around the lateral groove 7 in which the pin 11 engages and lifted.

そしてそのまま連結片４を基台１の方に下げると、ピン
１１を係合させていた横溝７の一つから外すことができ
る。Then, by lowering the connecting piece 4 toward the base 1, the pin 11 can be removed from one of the lateral grooves 7 with which it was engaged.

この状態で可動締付部３と共に基台１の上を移動し、連
結片４の底を開穿８の底部８ａｌこ着座させることによ
って横溝７の一つにその脚１０のピン１１を再び嵌め込
むことができる。In this state, the pin 11 of the leg 10 is refitted into one of the horizontal grooves 7 by moving on the base 1 together with the movable clamping part 3 and seating the bottom of the connecting piece 4 on the bottom 8al of the opening 8. can be included.

このようにこのバイスは、連結片４と脚１０、ピン１１
からなる掛は金を、基台１下面に設けたラック状の溝に
順次掛は換えて、可動締付部３の大きな位置換えが簡単

としであるので、ボルト６のねじはピッチの小さいもの
を用いることができ、締付後の弛みも生じない利点があ
る。In this way, this vise consists of the connecting piece 4, the leg 10, and the pin 11.
By sequentially replacing the hooks with the rack-shaped grooves provided on the underside of the base 1, the movable tightening section 3 can be easily changed in position, and the connection piece 4 and the movable tightening section 3 can be easily changed. Since the bolts 6 are relatively movable and the positions of the bolts 6 can be adjusted within a small range, the threads of the bolts 6 can have a small pitch, which has the advantage of not loosening after tightening. be.

付部２側部分は肉厚が極めて薄くなり、重量の大きなも
のの締付けに使用していると、溝孔５の方に面した部分
に亀裂が生ずる問題があった。In the vise proposed in Japanese Utility Model Publication No. 50-45753, the leg 10 is extended downward from the base 1 through the through hole 9 at an angle of 45 degrees from the bottom of the connecting piece 4. The wall thickness of the portion of the movable tightening portion 3 on the fixed tightening portion 2 side through which the through hole 9 passes is extremely thin, and when used for tightening heavy objects, the portion facing the slot hole 5 becomes extremely thin. There was a problem of cracks forming.

ようにすると、連結片４による可動締付部３の基台１へ
の圧着力の作用部が被固定物を締付ける面から遠くなる
ため可動締付部３の被固定物を締付ける面に近い部分が
基台１に対して浮き易く不安定番こなる問題が生ずる。This problem can be solved by increasing the thickness of the movable clamping part 3 from the opening 8 to the part facing the fixed clamping part 2. Since the part that applies the crimping force to the base 1 is far from the surface that clamps the object, the part of the movable clamping section 3 that is close to the surface that clamps the object tends to float relative to the base 1, resulting in unstable rotation. arise.

本案では、連結片４の脚１０を第２図に示すように側面
から見て屈曲したので、連結片４による可動締付部３の
基台１への圧着力の作用部を、可動締付部３の被固定物
を締付ける面から遠くならないように形成できるため、
締付距離を変えることを迅速にでき、弛みにくい。In this case, the legs 10 of the connecting piece 4 are bent when viewed from the side as shown in FIG. Because it can be formed so that the object to be fixed in part 3 is not far from the surface to be tightened,
The tightening distance can be changed quickly and does not loosen easily.

重量の太きいものを固定する大型バイスでは、可動締付
部３の重量も大きくなる。In a large vise that fixes a heavy object, the weight of the movable tightening part 3 is also large.

可動締付部３を移動するために、ピン１１を横溝７から
外したとき、基台１が傾斜していると、基台１を固定締
付部２の方に滑り落ち手を挟んだりする危険がある。When the pin 11 is removed from the horizontal groove 7 in order to move the movable clamping part 3, if the base 1 is tilted, the base 1 may slide toward the fixed clamping part 2 and cause your hand to get caught. There is a danger.

ところが本案ではボルト６はつる巻きはね１４によって
開穿８の底部８ａの方に常時押えられているので、基台
１を水平に対しかなり傾斜して用いても、ピン１１が横
溝７から外れて移動することはない。However, in this case, the bolt 6 is always held down by the helical spring 14 toward the bottom 8a of the opening 8, so even if the base 1 is used at a considerable inclination to the horizontal, the pin 11 will not come off the horizontal groove 7. It never moves.

また可動締付部３を移動するために、つる巻きばね１４

締付部３を移動しないように保持するので、手を固定締
付部２と可動締付部３との間（こ挟んだりする危険も防
止できる。Also, in order to move the movable tightening part 3, a helical spring 14 is used.
When the rear end of the bolt 6 is lifted up against the force, the bolt 6 is immediately pulled back to be parallel to the base 1 by the helical spring 14 even if the bolt 6 or the movable tightening part 3 is removed. Since the pin 11 immediately fits into the horizontal groove 7 and holds the movable clamping part 3 so that it does not move, there is no danger of your hand being caught between the fixed clamping part 2 and the movable clamping part 3. can also be prevented.

。In order to remove the pin 11 from the horizontal groove 7, it is necessary to tilt the connecting piece 4 as shown by the chain line in FIG. 5. However, as shown in FIG. This operation can be made easier by adding .

このように本案は操作が容易で確実に固定でき、安全な
大型バイスを提供しうるものである。As described above, the present invention can provide a large-sized vise that is easy to operate, can be securely fixed, and is safe.
