Description

【0001】
【産業上の利用分野】
この発明は、保持枠に螺旋軸棒を螺合させた構成のクランプの改良に関するものである。
【0002】
【従来の技術】
木材加工や金属加工に際しては、材料の仮組や仮止めを行なう必要がある場合が多いのであるが、このような場合には、保持枠の下方部に受け部を形成するとともに、受け部に向けて螺旋軸棒の先端部が下降するように螺合させた構成の手動式のクランプが使用されるのが一般的である。
【0003】
【発明が解決しようとする課題】
このようなクランプを使用して作業を行なう場合、固定しようとする材料を一方の手で持って保持するとともに、クランプの保持枠を他方の手でもって所定箇所に配置させた後、螺旋軸棒を回転させることによって行なうのであるが、締め付け操作に移ろうとする際にクランプの保持枠から手を離す必要があり、その際にクランプが位置ずれしてしまうことが多いのである。
【0004】
このようなことを防止しようとすると、クランプの保持枠を小指と薬指とで引っ掛けた状態にして保持する一方、親指と人指し指で螺旋棒軸の外周部を摘み、固定しようとする部材からクランプが脱落しない状態となるまで回転させた後、螺旋棒軸の上方部に取り付けたハンドルを回動させることによって強固な締め付け状態にるすという方法をとる必要があるのである。
【0005】
しかし、螺旋棒軸の外周表面部が平滑状となっていた場合、螺旋棒軸を人指し指と親指とで摘んで回動させようとしても、滑べってしまて迅速な回動操作が出来ず、被保持材料からクランプがずれない状態になるまで締め付けるのに苦労するという欠点があるのである。特に、手袋をはいた状態で作業するような場合、そのような欠点が顕著になるのである。
【0006】
このような欠点を除去するため、螺旋軸棒を回転操作させるリングを指で操作させ得る位置に配置させ、リングを人指し指と親指で摘んで回動せせるように構成したものも存在するのであるが、このようなものは、クランプの部品点数を多くするばかりか、部品の加工工程や組立工程を複雑にするという欠点があるのである。
【0007】
この発明は、従来の構成のものにみられたこのような欠点を除去しようとするものである。
【0008】
【課題を解決するための手段】
この発明は、保持枠の下方部に受け部を形成するとともに、受け部に向けて螺旋軸棒の先端が下降するようにして螺合させた構成のクランプにあって、螺旋軸棒の外周山部に凹凸部を形成した構成とすることよって、クランプの使い勝手を向上させようとするものである。
【0009】
【実施例】
図面にもとづいて、この発明の一実施例を説明すると、クランプ1は、図1ないし図3に示すとおり、保持枠5の上腕部端部に、外周部に凹凸部3を形成した螺旋軸棒2を螺合させるととにも、螺旋棒軸2を回動させることによって、螺旋軸棒2の先端部を保持枠5に形成した受け止め部6向けて前進下降させるように形成した構成となっているのである。
【0010】
すなわち、保持枠5は、図1ないし図3に示すとおり、「コ」の字状に屈曲形成した金属体の上腕部の端部7に、螺旋溝を形成した孔を形成するとともに、下腕部の端部に、螺旋軸棒2の先端部が当接する受け止め部6を形成した構成となっているのである。
【0011】
一方、螺旋軸棒2は、図1ないし図3に示すとおり、保持枠5に形成した螺旋孔に螺合さる螺旋溝が形成されるとともに、その螺子山部の外周部に凹凸部3を形成した構成となっており、また、その上方端部には、螺旋軸棒2を回転操作するためのハンドル8が形成されており、さらに、下方端部には、押圧板4を配置形成した構成となっているのである。
【0012】
【発明の効果】
この発明にかかるクランプは、上記のような構成であって、その使用に際し、図3に示すように、一方の手で材料を保持し、他方の手でクランプを保持しながら2本の指で螺旋軸棒2の回転操作を行なうことができるので、クランプでの固定作業を正確、迅速に行なうことができるし、また、従来の構成のものに比べ、その構成が単純となり、製造コストを低減できるという利点があるのである。
【0013】
すなわち、クランプでの仮止め操作に際しては、一方の手で材料を固定するとともに、他方の手でクランプをもって締め付け作業を行なう場合が多いのであるが、この発明にかかるクランプにあっては、材料の仮固定までの操作を、クランプから手を離すことなく行なうことができるとともに、その仮固定の後、ハンドル8を手でもって本格的な締め付け操作に移ることができるので、迅速かつ確実な締め付け操作を行ない得るという便利さがあるのである。
【0014】
また、螺旋軸棒の長手方向に沿って溝を形成するとともに、その溝に係合する突起を有し、螺旋軸棒の長手方向に沿って移動する操作リングを配置させることによって同様の操作性をもたせた従来のものに比べ、部品点数や部材への加工工程を少なくすくことができ、製造コストの低減を図ることができるという利点があるのである。

[Industrial application fields]
The present invention relates to an improvement of a clamp having a configuration in which a helical shaft rod is screwed into a holding frame.
[0002]
[Prior art]
In wood processing and metal processing, it is often necessary to temporarily assemble or temporarily fix the material. In such a case, a receiving portion is formed below the holding frame, and the receiving portion Generally, a manual clamp having a configuration in which the tip of the spiral shaft bar is lowered so as to be lowered is used.
[0003]
[Problems to be solved by the invention]
When working with such a clamp, hold and hold the material to be fixed with one hand and place the holding frame of the clamp in place with the other hand, then the spiral shaft rod However, it is necessary to release the hand from the holding frame of the clamp when moving to the tightening operation, and the clamp is often misaligned.
[0004]
In order to prevent such a situation, the clamp holding frame is held with the little finger and ring finger hooked, while the outer periphery of the spiral rod shaft is picked with the thumb and index finger, and the clamp is removed from the member to be fixed. It is necessary to take a method of rotating the handle attached to the upper part of the spiral rod shaft and turning it into a firm tightened state after rotating until it does not fall off.
[0005]
However, when the outer peripheral surface of the spiral rod shaft is smooth, even if you try to rotate the spiral rod shaft with your index finger and thumb, you will not be able to rotate quickly. There is a drawback that it is difficult to tighten until the clamp is not displaced from the material to be held. In particular, when working with gloves on, such drawbacks become prominent.
[0006]
In order to eliminate such drawbacks, there is a structure in which a ring for rotating a spiral shaft rod is arranged at a position where it can be operated by a finger, and the ring is picked and rotated by an index finger and a thumb. Such a method not only increases the number of clamp parts, but also has the disadvantage of complicating parts processing and assembly processes.
[0007]
The present invention seeks to eliminate such drawbacks found in conventional configurations.
[0008]
[Means for Solving the Problems]
The present invention provides a clamp having a configuration in which a receiving portion is formed in a lower portion of a holding frame and screwed so that a tip of a helical shaft rod is lowered toward the receiving portion, and an outer peripheral mountain of the helical shaft rod It is intended to improve the usability of the clamp by adopting a configuration in which the concavo-convex part is formed in the part.
[0009]
【Example】
An embodiment of the present invention will be described with reference to the drawings. A clamp 1 includes a spiral shaft rod having a concave and convex portion 3 formed on an outer peripheral portion at an end portion of an upper arm portion of a holding frame 5 as shown in FIGS. 2 is screwed together, and the spiral rod shaft 2 is rotated so that the tip of the spiral shaft rod 2 is moved forward and down toward the receiving portion 6 formed on the holding frame 5. -ing
[0010]
That is, as shown in FIGS. 1 to 3, the holding frame 5 has a hole in which a spiral groove is formed in the end portion 7 of the upper arm portion of the metal body bent in a “U” shape, and the lower arm The receiving part 6 which the front-end | tip part of the spiral shaft 2 contact | abuts in the edge part of a part is formed.
[0011]
On the other hand, as shown in FIGS. 1 to 3, the spiral shaft rod 2 is formed with a spiral groove that is screwed into a spiral hole formed in the holding frame 5, and an uneven portion 3 is formed on the outer periphery of the screw thread portion. Further, a handle 8 for rotating the spiral shaft rod 2 is formed at the upper end portion thereof, and a pressing plate 4 is disposed and formed at the lower end portion thereof. It is.
[0012]
【The invention's effect】
The clamp according to the present invention is configured as described above, and when used, as shown in FIG. 3, the material is held by one hand and the clamp is held by the other hand, with two fingers. Since the rotation of the spiral shaft rod 2 can be performed, the fixing operation with the clamp can be performed accurately and quickly, and the structure is simpler and the manufacturing cost is reduced as compared with the conventional structure. There is an advantage of being able to do it.
[0013]
That is, in the temporary fixing operation with the clamp, the material is fixed with one hand and the clamping operation is often performed with the clamp with the other hand. In the clamp according to the present invention, The operation up to the temporary fixing can be performed without releasing the hand from the clamp, and after the temporary fixing, the handle 8 can be moved to a full-scale tightening operation by hand, so that a quick and reliable tightening operation can be performed. There is convenience that can be performed.
[0014]
Similar operability is achieved by forming a groove along the longitudinal direction of the spiral shaft rod, and having an operation ring that has a protrusion that engages with the groove and moves along the longitudinal direction of the spiral shaft rod. Compared to the conventional one having the above, there are advantages that the number of parts and the number of processing steps for the member can be reduced, and the manufacturing cost can be reduced.
