Description
本考案はレンチに関するものであり、特に、重量を減らす、強化結構、中空ハンドルを持つと言うレンチを指す。 The present invention relates to a wrench, and particularly refers to a wrench that reduces weight, has a reinforced structure, and has a hollow handle.
ツールの発展が相当に成熟した産業であるから、レンチの製造業者は絶えず進歩を求めて、いつも使いやすいし、製造容易かつコスト節約の設計の念をいれる。レンチのハンドルは中のつまったものから、中空式へ変更し、さらに、重量及びコストを省く設計へ進化しつつある。 Since the development of tools is a fairly mature industry, wrench manufacturers are continually looking for progress and always have an easy-to-use, easy-to-manufacture and cost-saving design. The handle of the wrench has been changed from being jammed to a hollow type, and is further evolving into a design that saves weight and cost.
しかし、従来から、既知の設計はやはり、様々な欠陥がある。ゆえに、本考案者は長い間に、ツール（tool)の製造にたずさわってきた研究開発の経験により、重量を減らす、十分に強度があると言うハンドル（handle)を持つレンチを開発したい。 However, traditionally known designs still have various deficiencies. Therefore, the inventor wants to develop a wrench with a handle that is strong enough to reduce weight, based on research and development experience that has been involved in the manufacture of tools for a long time.
図１４を参照されたい。それは一体化成型するように、中のつまったレンチである。そのレンチのヘッド１、ネック２及びハンドル３が一体化成型ように鍛造されて、整体がソリッド（solid）状だから、製造プロセスのコストがよくかかるばかりでなく、レンチの重量も大幅に高められる。ハンドル３が一本のレンチの体積の最大箇所だから、ハンドル３の重量が高められると、ユーザーがレンチを使うときの負担を招いて、ユーザーの体力の損耗を加速させ、作業の効率を相対的に低降させる。そして、研究開発しなければならない。 See FIG. It is a wrench packed inside as if it were integrally molded. Since the head 1, neck 2 and handle 3 of the wrench are forged so as to be integrally formed and the trim is solid, the manufacturing process is not only costly, but the weight of the wrench is greatly increased. Since the handle 3 is the largest part of the volume of one wrench, if the weight of the handle 3 is increased, the burden on the user when using the wrench is increased, the wear of the user's physical strength is accelerated, and the work efficiency is relatively increased. To lower. And research and development must be done.
図１５を参照されたい。それは中空式のレンチである。中のつまったレンチの重量問題を改善するために、管状のハンドル４とヘッド５が接続されて、レンチを形成する。残念ながら、中空状のハンドル４を成形しているうちに、ハンドル４の壁の厚さを等しくして、確実に重量を減らす目的を達成するが、そんな結構ならば、作動のときに、より大きなトルクを受けることが出来ない。つまり、ハンドル４は小さい外径の接合箇所６及び大きい外径の握り箇所７を持ち、両者の間に、漸進収縮箇所８は形成される。同じの壁の厚さを持つハンドル４を作動しているうちに、手が握り箇所７を握る。そのときに、中空状の接合箇所６および漸進収縮箇所８は作動のトルクを受けるので、いつも、トルク、切断力の大き過ぎるせいで、ハンドル４の使用強度の不足、断裂を招く。それは依然として改善しなければならない。 See FIG. It is a hollow wrench. In order to improve the weight problem of the jammed wrench, the tubular handle 4 and the head 5 are connected to form a wrench. Unfortunately, while the hollow handle 4 is being molded, the wall thickness of the handle 4 is made equal to achieve the purpose of reliably reducing the weight, but if that's fine, more Cannot receive large torque. That is, the handle 4 has a joint portion 6 having a small outer diameter and a grip portion 7 having a large outer diameter, and a progressive contraction portion 8 is formed between the two. While operating the handle 4 with the same wall thickness, the hand grips the grip 7. At that time, since the hollow joint portion 6 and the progressive contraction portion 8 receive an operating torque, the handle 4 is insufficiently used and is always torn due to excessive torque and cutting force. It still has to improve.
前掲の様々な問題を解決するために、本考案の提案者は長い間に、ツールの製造にたずさわってきた研究開発の経験により、重量を減らす、十分の強度があると言うハンドルを持つ実用のレンチを開発したい。数回に、開発したり、改良したり工夫したあとで、ようやく、本考案の重量を低減するレンチを設計した。従来から、既知のレンチの本体から招いた様々な欠点を克服する。確かに、新規性、進歩性を持つ創案だと言える。 In order to solve the various problems mentioned above, the proponent of the present invention has a practical handle with a handle that is strong enough to reduce weight due to research and development experience that has been involved in the manufacture of tools for a long time. I want to develop a wrench. After developing, improving, and devising several times, I finally designed a wrench that reduces the weight of the device. Traditionally, it overcomes the various drawbacks incurred from known wrench bodies. Certainly, it can be said that it is a novelty and inventive step.
要するに、本考案により、強化結構、中空ハンドルを持つレンチの解決したい技術問題は既知の中のつまったハンドルが重い重量、高い材料コストなど問題を招いて、既知の中空レンチが同じの壁の厚さのせいで、頻繁にトルク切断力の大き過ぎるせいで、ハンドル４の使用強度の不足、断裂を招くと言うことが分かった。本考案の提案者は前掲の問題を改善するために、開発したり、改良したり工夫したあとで、ようやく、材料を省いて、重量が軽い、十分な強度のレンチの本体を持ち、ハンドルに力を入れても断裂しないという製品を開発した。 In short, according to the present invention, the technical problem to be solved for the wrench with a hollow handle, which is reinforced by the present invention, causes problems such as the heavy weight of the known handle and the high material cost, and the known hollow wrench has the same wall thickness. For this reason, it has been found that the handle 4 is insufficiently used and torn due to frequent excessive torque cutting force. The proposer of the present invention has developed, improved, and devised to improve the above-mentioned problems. Finally, the material is saved, the weight is light, and the wrench has a sufficiently strong wrench body. Developed a product that does not tear even if force is applied.
本考案により、強化結構で中空ハンドルを持つレンチは、主に次の要素から構成される。ヘッド、ネックの一端はヘッドに接続される。
ハンドルは握り部と接合部を持つ。接合部はネックの他端に接続される。握り部と接合部との間に、漸進収縮部が形成される。ハンドルの内部は中空状になるので、ハンドルの重量を減らす効果がある。ハンドルの接合部における壁の厚さは漸進収縮部の壁の厚さより大きいし、漸進収縮部の壁の厚さは握り部の壁の厚さより大きいので、より大きいトルクを受けるばかりでなく、ハンドルの結構強度も強化される。
According to the present invention, a wrench having a reinforced structure and a hollow handle mainly comprises the following elements. One end of the head and neck is connected to the head.
The handle has a grip and a joint. The joint is connected to the other end of the neck. A progressive contraction is formed between the grip and the joint. Since the inside of the handle is hollow, there is an effect of reducing the weight of the handle. The wall thickness at the joint of the handle is greater than the wall thickness of the progressive contraction, and the wall thickness of the progressive contraction is greater than the thickness of the grip wall, so that not only will it receive more torque, The strength of this is also strengthened.
本考案により、強化結構、中空ハンドルを持つレンチは中空状のハンドルで、材料及び重量を省く。接合部の壁の厚さd4＞漸進収縮部の壁の厚さd3＞弧状部の壁の厚さd2＞握り部の壁の厚さd1を経由して、厚い壁の厚さの接合部は大きいトルクを受ける。薄い壁の厚さの握り部はただ握るために採用される。それで、同時に重量の減少及び結構の強化を考える。漸進収縮部の壁の厚さも弧状部の壁の厚さより大きいので、漸進収縮部は次第に収縮しても、容易に、断裂しない。それで、依然として、握り部の作動回転のトルクを受けることができる。 According to the present invention, a wrench having a reinforced structure and a hollow handle is a hollow handle, saving material and weight. The wall thickness d4 of the joint portion> the wall thickness d3 of the progressive contraction portion> the wall thickness d2 of the arcuate portion> the wall thickness d1 of the grip portion Receive large torque. The thin wall thickness grip is adopted for holding only. So, at the same time, consider weight reduction and good strengthening. Since the wall thickness of the progressive contraction portion is also larger than the wall thickness of the arcuate portion, even if the progressive contraction portion contracts gradually, it does not easily tear. Thus, the torque of the operating rotation of the grip portion can still be received.
本考案の採用される技術、手段及び効果などを理解いただくために、以下、さらに具体的な実施例に図面をあわせて詳しく説明する。 In order to understand the technology, means, effects, etc. employed by the present invention, further detailed description will be given below with reference to specific examples.
まず、図１〜図３を参照されたい。それは本考案の立体外観図及び立体分解図である。本考案により、中空のハンドル、強化結構、中空ハンドルを持つレンチは主にヘッド１０、ネック２０、ハンドル３０など要素から形成される。ヘッド１０の中に、ラチェット ユニット１１、方向の変更スイッチ１２がある。ヘッド１０は次第に収縮するように円い管状のネック２０を形成する。それで、ネック２０の一端は大直径として、ヘッド１０に接続させる。他端は小直径として、ハンドル３０に接続させる。本例ならば、ヘッド１０とネック２０は単一ユニットを採用して、鍛造方式で加工されるので、優れた強度が得られる。 First, please refer to FIGS. They are a three-dimensional external view and a three-dimensional exploded view of the present invention. According to the present invention, a hollow handle, a reinforced structure, and a wrench having a hollow handle are mainly formed from elements such as the head 10, the neck 20, and the handle 30. Within the head 10 are a ratchet unit 11 and a direction change switch 12. The head 10 forms a round tubular neck 20 so as to gradually contract. Therefore, one end of the neck 20 has a large diameter and is connected to the head 10. The other end has a small diameter and is connected to the handle 30. In this example, since the head 10 and the neck 20 employ a single unit and are processed by a forging method, excellent strength can be obtained.
ハンドル３０は握り部３１を具有する。握り部３１の両端には、それぞれ小直径の接合部３２及び尾部３３がある。尾部３３は内へ向かって折り曲げるように、軸方向の孔３３１を形成する。接合部３２の外直径はネック２０の一端と同じであり、摩擦熔接の方式で接合される。握り部３１は接合部３２と比較すると、より大きな外径があるので、手で簡易に握る。握り部３１と接合部３２との接続箇所は漸進収縮部３４を形成する。漸進収縮部３４が握り部３１に隣接する箇所は弧状部３４１になる。つまり、大きい直径の握り部３１はまず、緩和かつ次第に収縮するように、弧状部３４１を形成したあとで、漸進収縮部３４から接合部３２まで小さい直径を形成する。その結果、ハンドル３０の曲線は平穏かつ緩和のような美観を具有する。また、外径が平穏かつ緩和のよう縮めると、応力の集中問題がないので、美観だけでなく、強度の問題も考えられる。 The handle 30 has a grip 31. At both ends of the grip portion 31, there are a small diameter joint portion 32 and a tail portion 33, respectively. The tail portion 33 is formed with an axial hole 331 so as to be bent inward. The outer diameter of the joint portion 32 is the same as that of one end of the neck 20 and is joined by a friction welding method. Since the grip portion 31 has a larger outer diameter compared to the joint portion 32, it is easily gripped by hand. A connection portion between the grip portion 31 and the joint portion 32 forms a progressive contraction portion 34. A portion where the progressive contraction portion 34 is adjacent to the grip portion 31 is an arc-shaped portion 341. That is, the grip portion 31 having a large diameter first forms an arc-shaped portion 341 so as to relax and gradually contract, and then forms a small diameter from the progressive contraction portion 34 to the joint portion 32. As a result, the curve of the handle 30 has a calm and relaxed aesthetic. In addition, when the outer diameter is reduced to be calm and relaxed, there is no stress concentration problem, so not only aesthetics but also strength problems can be considered.
ハンドル３０の中空状は尾部３３から、接合部３２まで通るので、ハンドル３０の整体が貫通状になる。ハンドル３０は中空管を採用すれば、生産のコストを低降することができる。ハンドル３０の構造を調べて見ると、握り部の壁の厚さd1、弧状部の壁の厚さd2、漸進収縮部の壁の厚さd3、接合部の壁の厚さd4が形成される。握り部の外径Ｄ１はどこでも等しいが、厚さもどこでも等しい。接合部の外径Ｄ４及び厚さはどこでも等しい。弧状部の外径Ｄ２及び漸進収縮部の外径Ｄ３ならば、握り部３１から、接合部３２までは大から小まで変化するように、すなわち、Ｄ１＞Ｄ２＞Ｄ３＞Ｄ４になる。それらの厚さも薄から、厚まで次第に変化してある。各壁の厚さの関係は接合部の壁の厚さd4＞漸進収縮部の壁の厚さd3＞弧状部の壁の厚さd2＞握り部の壁の厚さd1という構造である。厚い壁の接合部３２を経由して、大きなトルクを受けて、薄い壁の厚さの握り部３１はただ握るために採用される。それで、同時に重量の減少及び結構の強化を考える。漸進収縮部の壁の厚さｄ３の設計を経由して、漸進収縮部３４は次第に収縮しても、容易に、断裂しない。それで、依然として、握り部３１の作動回転のトルクを受けることができる。 Since the hollow shape of the handle 30 passes from the tail portion 33 to the joint portion 32, the trimming body of the handle 30 becomes a penetrating shape. If the handle 30 is a hollow tube, the production cost can be reduced. When the structure of the handle 30 is examined, a grip wall thickness d1, an arcuate wall thickness d2, a progressive contraction wall thickness d3, and a joint wall thickness d4 are formed. . The outer diameter D1 of the grip portion is the same everywhere, but the thickness is the same everywhere. The outer diameter D4 and thickness of the joint are equal everywhere. If the outer diameter D2 of the arc-shaped portion and the outer diameter D3 of the progressive contraction portion are changed from large to small from the grip portion 31 to the joint portion 32, that is, D1> D2> D3> D4. Their thickness changes gradually from thin to thick. The relationship between the thicknesses of the respective walls is a structure in which the wall thickness d4 of the joint portion> the wall thickness d3 of the progressive contraction portion> the wall thickness d2 of the arcuate portion> the wall thickness d1 of the grip portion. Under the large wall joint 32, the large wall thickness grip 31 is employed for gripping. So, at the same time, consider weight reduction and good strengthening. Through the design of the wall thickness d3 of the progressive contraction, the progressive contraction 34 does not tear easily even if it gradually contracts. Therefore, the torque of the operation rotation of the grip portion 31 can still be received.
ハンドル３０の中空管で、生産のコストを低降することができる。それは材料の節約及び重量の低減など要因を考える。どころが、薄い壁のせいで、握り部３１を握って、力を入れ、レンチを回して、スクリューを駆動する場合に、握り部３１は力が大き過ぎるので、いつも内へ凹むようになる。幸いに、本考案ならば、尾部３３に、弧状の折り曲げ３３２が形成され、内へ収縮するので、尾部３３はより大きい力を受けても内へ凹まない。つまり、握り部３１を握って、力を施すときに、力は弧状の折り曲げ３３２へ分散される。また、ハンドル３０の空間を経由して、ハンドル３０は重量を減らす効果に役立つばかりでなく、弧状の折り曲げ３３２を経由して、ハンドル３０も大きな握りの力を受けることができる。 The hollow tube of the handle 30 can reduce the production cost. It considers factors such as material savings and weight reduction. On the other hand, when gripping the grip 31 and applying force, turning the wrench and driving the screw due to the thin wall, the grip 31 is too strong so that it always dents inward. Fortunately, according to the present invention, an arc-shaped fold 332 is formed in the tail portion 33 and contracts inward, so that the tail portion 33 is not recessed inward even when receiving a larger force. That is, when gripping the grip portion 31 and applying force, the force is distributed to the arc-shaped bend 332. Further, the handle 30 not only helps the effect of reducing the weight via the space of the handle 30, but also the handle 30 can receive a large gripping force via the arc-shaped bend 332.
ちなみに、ハンドル３０の中空状で、ツールやスクリューやボルトやナットなどを放置するので、ユーザーは収納の空間があって、別に用意することがいらない。 Incidentally, since the handle 30 is hollow and the tools, screws, bolts, nuts and the like are left unattended, the user has a storage space and does not need to prepare it separately.
カバー４０は着脱に、尾部３３の孔３３１に結合できるので、ハンドル３０をクローズドする。カバー４０を被せて、ハンドル３０の尾部３３結構強度は向上される。 Since the cover 40 can be detachably coupled to the hole 331 of the tail 33, the handle 30 is closed. Covering the cover 40, the strength of the tail 33 of the handle 30 is improved.

Claims (3)
該ハンドルは握り部と接合部を含み、接合部はネックに接続され、握り部と接合部との間に漸進収縮部は形成され、ハンドルの内部は中空状になるので、ハンドルの重量を減らす効果があり、ハンドルの接合部における壁の厚さは漸進収縮部の壁の厚さより大きく、漸進収縮部の壁の厚さは握り部の壁の厚さより大きいので、より大きいトルクを受けるばかりでなく、ハンドルの結構強度も強化されることを特徴とする中空ハンドルを持つレンチ。 Mainly provided with head, neck and handle,
The handle includes a grip portion and a joint portion, the joint portion is connected to the neck, a progressive contraction portion is formed between the grip portion and the joint portion, and the inside of the handle becomes hollow, thus reducing the weight of the handle Effective, the wall thickness at the joint of the handle is greater than the wall thickness of the progressive contraction, and the wall thickness of the progressive contraction is greater than the thickness of the grip wall, so that it only receives more torque. There is also a wrench with a hollow handle characterized in that the strength of the handle is also enhanced.
