Description

本考案はレンチに関し、特にラチェット機能を備えるラチェットレンチに関する。 The present invention relates to a wrench, and more particularly to a ratchet wrench having a ratchet function.

レンチ（以下はスパナを同意語として使用する）は、てこ原理を利用して、ボルト、ナット、又は素手で回しにくい他の締め具を回す手工具である。スパナは通常、把持部のいずれかの一端又は両端に設けられる開口部で締め具を挟み、かつ使用者が把持部の他端に回動方向に沿う外力を加えることによって、締め具を回すことができる。スパナの種類がかなり多く、そのうちの一種がモンキーレンチである。モンキーレンチを使用する頻度が非常に高い原因は、サイズが変わってもスパナを換える必要がなく、開口部の大きさを自由に調節することにより、各種サイズの締め具を挟むことができることにある。使用者にとって、一つのモンキーレンチで用意することで、複数の固定サイズのスパナに代わることができるので、極めて大きい利便性と適用性をもたらすことができる。 A wrench (hereinafter using a spanner as a synonym) is a hand tool that uses the lever principle to turn bolts, nuts, or other fasteners that are difficult to turn with bare hands. A spanner usually turns a fastener by pinching the fastener at an opening provided at one or both ends of the gripping portion, and a user applies an external force along the rotation direction to the other end of the gripping portion. Can do. There are quite a few types of spanners, one of which is a monkey wrench. The cause of the very high frequency of using an adjustable wrench is that it is not necessary to change the wrench even if the size changes, and it is possible to clamp various sizes of fasteners by freely adjusting the size of the opening. . For a user, by preparing with one monkey wrench, it is possible to replace a plurality of fixed-size spanners, which can bring great convenience and applicability.

一般のラチェット機能を有するレンチは、米国特許第８１３６４２９号のREVERSIBLE MONKEY WRENCH（可逆モンキーレンチ）（特許文献１）に記載されるとおり、把持部（handle）と、ヘッド部（head）と、摺動顎（slidable jaw）と、軸棒（axial rod）と、ウォーム歯車（worm gear）とを含む。ヘッド部は、把持部の一端に形成され、固定顎（fixed jaw）と、摺動軌道（sliding rail）と、収容溝（receiving slot）とを含む。把持部は、接続端（connecting end）を有し、接続端は、稼働当接面（working abutting face）とアイドル当接面（idle abutting face）とを含む。可動ピン（movable pin）は、ヘッド部と接続端との間に設けられ、摺動顎の摺動棒（sliding rod）は、摺動可能に摺動レールに摺設され、軸棒とウォーム歯車とは、収容溝に収容される。ウォーム歯車と摺動棒とが互いに係合することによって、摺動顎が固定顎に相対して摺動することを制御し、摺動顎と固定顎との間に形成する開度を調節することによって、様々なサイズの締め具を挟持することができる。 As described in US Pat. No. 8,136,429, REVERSIBLE MONKEY WRENCH (Patent Document 1), a wrench having a general ratchet function is provided with a grip portion, a head portion, and a sliding portion. Includes a slidable jaw, an axial rod, and a worm gear. The head part is formed at one end of the grip part and includes a fixed jaw, a sliding rail, and a receiving slot. The gripping portion has a connecting end, and the connecting end includes a working abutting face and an idle abutting face. The movable pin (movable pin) is provided between the head portion and the connection end, and the sliding rod of the sliding jaw is slidably mounted on the sliding rail, and the shaft rod and the worm gear. Is housed in the housing groove. When the worm gear and the sliding rod are engaged with each other, the sliding jaw is controlled to slide relative to the fixed jaw, and the opening formed between the sliding jaw and the fixed jaw is adjusted. Thus, various sizes of fasteners can be clamped.

前述スパナを時計方向へ回すとき、可動当接面がヘッド部に当接し、可動ピンが上方に押し上げられる。これによって、可動ピンの一つの平面（plane surface）がウォンの当接端（abutting end）に当接される。したがって、摺動顎と固定顎とで六角ナットをしっかり挟んで、回すことができる。前述スパナを反対方向に回すとき、可動当接面がヘッド部から離れるとともに、アイドル当接面がヘッド部に当接される。そして、把持部をヘッド部に相対して所定の角度を回すとき、第２ばね（second spring）が下方に押し下げられるので、可動ピンは、可動ピンの平面がウォーム歯車の当接端から離脱することを可能にする。また、ナットが、第３ばね（third spring）が提供する弾性付勢力より大きい水平方向の分力を摺動顎に与えて、摺動顎とウォーム歯車が、固定顎から離れる方向に滑動するので、ラチェット運動が発生する。 When the spanner is rotated clockwise, the movable contact surface comes into contact with the head portion, and the movable pin is pushed upward. As a result, one plane surface of the movable pin is brought into contact with the abutting end of the won. Therefore, the hexagon nut can be firmly sandwiched between the sliding jaw and the fixed jaw and rotated. When the spanner is rotated in the opposite direction, the movable contact surface is separated from the head portion, and the idle contact surface is contacted with the head portion. When the gripping portion is rotated at a predetermined angle relative to the head portion, the second spring is pushed downward, so that the plane of the movable pin is detached from the contact end of the worm gear. Make it possible. In addition, the nut applies a horizontal component force to the sliding jaw that is greater than the elastic biasing force provided by the third spring, and the sliding jaw and the worm gear slide in a direction away from the fixed jaw. , Ratchet movement occurs.

しかし、前述スパナは、ラチェット機能を達成するために設けた各構成品の構造が複雑で、組立が難しく、製造コストも高い問題を有している。さらに、把持部とヘッド部との間に、一つの連結軸（joint axle）のみが枢接されているため、構造強度が低すぎて、ナットを回すときの回動力を充分に堪えることができない。 However, the spanner has a problem that the structure of each component provided to achieve the ratchet function is complicated, difficult to assemble, and high in manufacturing cost. Furthermore, since only one joint axle is pivoted between the gripping part and the head part, the structural strength is too low to fully support the turning force when turning the nut. .

本考案の主な技術効果は、構造が単純で、組み立てが容易で、製造コストを大幅に低減することができ、かつラチェット効果を奏することができることである。 The main technical effects of the present invention are that the structure is simple, the assembly is easy, the manufacturing cost can be greatly reduced, and the ratchet effect can be achieved.

本考案による技術効果は、次のとおりである。締め具を固定顎の第１歯面と挟持部の第２歯面との間に挟んで、使用者が把持部を握って、駆動方向に締め具を回すとき、締め具が可動顎の挟持部に水平方向の分力を与えるので、可動顎が滑動できず、滑り溝に固定される。したがって、ラチェットレンチで締め具を駆動することができる。使用者が把持部を握って、駆動方向と反対する解放方向に締め具を回すとき、可動顎が滑り溝に相対して第１軸線に沿って摺動し、偏圧装置の偏圧具が収容溝の底部と制限具との間に圧縮されるので、ラチェットレンチで締め具を駆動することができない。すなわち、ラチェットレンチにラチェット運動が発生する。 The technical effects of the present invention are as follows. When the user holds the gripping part between the first tooth surface of the fixed jaw and the second tooth surface of the holding part and rotates the fastening part in the driving direction, the fastening part holds the movable jaw. Since a horizontal component force is applied to the part, the movable jaw cannot slide and is fixed to the sliding groove. Therefore, the fastener can be driven by the ratchet wrench. When the user grips the grip portion and turns the fastener in the release direction opposite to the driving direction, the movable jaw slides along the first axis relative to the sliding groove, and the biasing device of the biasing device is Since it is compressed between the bottom of the receiving groove and the restrictor, the fastener cannot be driven by the ratchet wrench. That is, ratchet motion occurs in the ratchet wrench.

本考案によるもう一つの技術効果は、次のとおりである。滑り溝は、第１軸線に沿って延伸され、かつ固定顎と対向する可動顎の一端に形成されている。受入穴は、第２軸線に沿って延伸され、可動顎の弧状端面に形成されている。第１軸線と第２軸線との間に所定の夾角が形成されるか、或いは滑り溝と受入穴がそれぞれ、第１軸線と第２軸線に沿って延伸され、２つの固定顎のいずれか一つに形成される。第１軸線と第２軸線との間に所定の夾角が形成されることによって、受入穴と滑り溝との間に所定の間隔が形成され、かつ両者が互いに平行しない。これによって、可動顎又は２つの可動顎のうちのいずれか一つがより高い構造強度を有することができる。 Another technical effect of the present invention is as follows. The sliding groove is formed at one end of the movable jaw extending along the first axis and facing the fixed jaw. The receiving hole extends along the second axis and is formed on the arcuate end surface of the movable jaw. A predetermined depression angle is formed between the first axis and the second axis, or the sliding groove and the receiving hole are extended along the first axis and the second axis, respectively, and one of the two fixed jaws. Formed into one. By forming a predetermined depression angle between the first axis and the second axis, a predetermined interval is formed between the receiving hole and the sliding groove, and they are not parallel to each other. Thereby, any one of the movable jaw or the two movable jaws can have a higher structural strength.

本考案のさらなる一つの技術効果は、次のとおりである。収容溝は、可動顎の接続部に形成されて、かつヘッド部の受入穴と連通されている。したがって、収容溝が可動顎の両端を貫通する必要がないため、可動顎がより高い構造強度を得ることができる。 Another technical effect of the present invention is as follows. The receiving groove is formed in the connecting portion of the movable jaw and communicates with the receiving hole of the head portion. Therefore, since the receiving groove does not need to penetrate both ends of the movable jaw, the movable jaw can obtain higher structural strength.

本考案のさらなる一つの技術効果は、次のとおりである。可動顎は、第１連結セクションと第２連結セクションとを含む。第１連結セクションと第２連結セクションは、長さ方向に沿って一体に形成され、第１連結セクションは、第１厚みを有し、第２連結セクションは、係止部の付近に位置し、かつ第２厚みを有する。第２厚みが第１厚みより大きいことによって、可動顎の構造強度が向上し、締め具を回すときの回動力に充分に堪えることができる。 Another technical effect of the present invention is as follows. The movable jaw includes a first connection section and a second connection section. The first connection section and the second connection section are integrally formed along the length direction, the first connection section has a first thickness, and the second connection section is located near the locking portion, And it has 2nd thickness. When the second thickness is larger than the first thickness, the structural strength of the movable jaw is improved, and the rotational force when the fastener is turned can be fully withstood.

Thereby, any one of the movable jaw 25 or the two movable jaws 21a can have high structural strength.

二、収容溝３３、３３ａは、可動顎３０、３０ａの接続部３２、３２ａに形成され、かつヘッド部２０、２０ａの受入穴２３、２３ａと連通されている。その場合、収容溝３３、３３ａが可動顎３０、３０ａの両端を貫通しないので、可動顎３０、３０ａがより高い構造強度を得ることができる。 Second, the receiving grooves 33 and 33a are formed in the connecting portions 32 and 32a of the movable jaws 30 and 30a, and communicate with the receiving holes 23 and 23a of the head portions 20 and 20a. In that case, since the accommodation grooves 33 and 33a do not penetrate both ends of the movable jaws 30 and 30a, the movable jaws 30 and 30a can obtain higher structural strength.

ホ、可動顎２５は、第１連結セクション２５１と第２連結セクションと２５２を含み、第１連結セクション２５１と第２連結セクション２５２は、長さ方向に沿って一体に形成されている。第１連結セクション２５１は、第１厚みＴ１を有し、第２連結セクション２５２は、係止部２６の付近に位置し、かつ第２厚みＴ２を有する。第２厚みＴ２が第１厚みＴ１より大きいことによって、可動顎２５の構造強度を向上させ、締め具を回すときの回動力に充分に堪えることができる。 The movable jaw 25 includes a first connection section 251 and a second connection section 252, and the first connection section 251 and the second connection section 252 are integrally formed along the length direction. The first connection section 251 has a first thickness T1, and the second connection section 252 is located in the vicinity of the locking portion 26 and has a second thickness T2. When the second thickness T2 is larger than the first thickness T1, the structural strength of the movable jaw 25 can be improved, and the turning force when the fastener is turned can be fully withstood.
