　本発明の工具落下防止具は、工具落下防止具Ａを更に改善したものである。 However, since the tool fall prevention tool A as shown in FIG. 6 requires a certain length in order to ensure a reachable range, the belt portion is slackened, and the belt portion is not suitable for moving or closed work. It becomes easy to get caught in the protruding part of the building. Moreover, it may slip down from the shoulder at the time of work or movement, and may restrain the movement of the worker.
The tool fall prevention tool of the present invention is a further improvement of the tool fall prevention tool A.
　図１に本発明の一実施形態に係る工具落下防止具Ｘの主要部分を示す。工具落下防止具Ｘは、肩掛けベルト１０、リール２０、金属製のワイヤー２１、引っ張りばねからなる緩衝器２３及び工具保持紐３０を有する。肩掛けベルト１０は、リング状に形成されたベルトであり、一般的な肩パッド１１が摺動自在に固定され、送りカン１２を途中に設けることで自在に長さを調節できるように形成されている。送りカン１２によって、リング状部分が、使用者の一方の肩と、この肩の反対側の脇の下から、脇の下から肩の長さ分下の位置までの範囲とを通るように調整する。この調整については後述する使用方法において詳述する。 FIG. 1 shows a main part of a tool fall prevention tool X according to an embodiment of the present invention. The tool fall prevention tool X includes a shoulder belt 10, a reel 20, a metal wire 21, a shock absorber 23 made of a tension spring, and a tool holding string 30. The shoulder belt 10 is a belt formed in a ring shape, and is formed so that a general shoulder pad 11 is slidably fixed and the length can be freely adjusted by providing a feed can 12 in the middle. Yes. The feed can 12 adjusts the ring-shaped portion so as to pass through one shoulder of the user and the range from the armpit on the opposite side of the shoulder to the position below the armpit to the shoulder length. This adjustment will be described in detail in the usage method described later.
　なお、肩掛けベルト１０の長さを調整する部材としては、送りカンに限らず、ピン式バックルを含むバックル等の他の部材を用いてもよい。また、肩掛けベルト１０にはリング１３が移動可能に固定されている。肩掛けベルト１０はシート部材より構成される。接続部材はリール２０、ワイヤー２１、及び緩衝器２３を含んでいる。リール２０、緩衝器２３は必要に応じて設けられ、接続部材はリール２０と緩衝器２３のいずれか一方又は両方とも含まなくともよい。また、肩パッド１１もなくともよい。ワイヤー２１は紐体となる。紐体は天然繊維、化学繊維等の繊維を撚り合わせた紐(string, cord, or rope)を用いることもできる。 It should be noted that the member for adjusting the length of the shoulder belt 10 is not limited to the feed can, and other members such as a buckle including a pin-type buckle may be used. A ring 13 is movably fixed to the shoulder belt 10. The shoulder belt 10 is composed of a sheet member. The connecting member includes a reel 20, a wire 21, and a shock absorber 23. The reel 20 and the shock absorber 23 are provided as necessary, and the connecting member may not include either one or both of the reel 20 and the shock absorber 23. Further, the shoulder pad 11 may be omitted. The wire 21 becomes a string. The string may be a string (string, cord, or rope) obtained by twisting fibers such as natural fibers and chemical fibers.
　リール２０は、金属製のワイヤー２１を内部に巻き取るボビンが偏平な中空円柱状のケース内に収められたものであって、ケースの外周面に設けられた穴からワイヤー２１が先端から引き出し可能に表出している。前記ボビンはゼンマイばねによって巻き取られる方向に付勢されるとともに、ロック機構によりボビンの回転が固定されており、ケース前面中央のボタンを押すことでロックを解除して、ワイヤー２１の引き出し、及びワイヤー２１のゼンマイばねによる自動巻取りが可能に形成されている。 The reel 20 has a bobbin that winds a metal wire 21 inside and is housed in a flat hollow cylindrical case. The wire 21 can be pulled out from the tip through a hole provided on the outer peripheral surface of the case. To express. The bobbin is urged in the direction of being wound by a spring, and the rotation of the bobbin is fixed by a lock mechanism. The lock is released by pressing a button at the center of the front of the case, and the wire 21 is pulled out. The wire 21 is formed so that it can be automatically wound by a spring.
　リール２０はケースの外周面に設けられた二重リング２４によって、肩掛けベルト１０のリング１３に連結され吊り下げられた状態で固定される。リング１３及び二重リング２４は、接続部材に含まれ、リール２０を肩掛けベルト２１に取りつけるために設けられる。ただし、リング１３及び二重リング２４は、リール２０を直接肩掛けベルト１０に取り付ける場合はなくともよい。ワイヤー２１の先端には、引張りばねからなる緩衝器２３を介して、ナスカン２２が固定されている。ナスカン２２は接続部材に含まれる。ナスカン２２は緩衝器２３と工具保持紐３０とを直接接続する場合はなくともよい。ワイヤーの長さは工具を直接ワイヤー先端に固定した際に作業者の腰の位置に工具が達する長さを有することが望ましいが、必要以上にワイヤー２１が繰出されることを防止するために当該工具が作業者の膝に達しない長さにする等、長さに制限を設けることが望ましい。このため、ここではワイヤー２１の長さは使用者の腕の長さ、例えば、約６０ｃｍ～約８０ｃｍに設定される。このように、ワイヤーの長さに制限を加えて、工具が使用者の足の接地面まで落ちないようにすることができる。
　リール２０は、専用品を作成してもよいが、リール式の工具落下防止用コード、落下防止ロープ、落下防止ワイヤー等として市販されている既製品を用いることが可能である。 The reel 20 is connected to the ring 13 of the shoulder belt 10 and fixed in a suspended state by a double ring 24 provided on the outer peripheral surface of the case. The ring 13 and the double ring 24 are included in the connecting member, and are provided for attaching the reel 20 to the shoulder belt 21. However, the ring 13 and the double ring 24 may not be attached to the shoulder belt 10 directly on the reel 20. An eggplant 22 is fixed to the tip of the wire 21 via a shock absorber 23 made of a tension spring. The eggplant 22 is included in the connection member. The eggplant 22 may not be directly connected to the shock absorber 23 and the tool holding string 30. It is desirable that the length of the wire has such a length that the tool reaches the waist position of the operator when the tool is directly fixed to the tip of the wire, but in order to prevent the wire 21 from being unnecessarily extended. It is desirable to limit the length such that the tool does not reach the operator's knee. Therefore, here, the length of the wire 21 is set to the length of the user's arm, for example, about 60 cm to about 80 cm. In this way, the wire length can be limited so that the tool does not fall to the ground plane of the user's foot.
The reel 20 may be a dedicated product, but it is possible to use an off-the-shelf product commercially available as a reel-type tool fall prevention cord, a fall prevention rope, a fall prevention wire, or the like.
　工具保持紐３０は、先端に輪３１ａが形成された紐体であって、先端の輪３１ａに基端を通して、「６」の字状に形成されたものである。工具保持紐３０は工具保持体となる。これによって先端位置に大きさを変更できる、工具を固定するためのリング状保持部３１が形成されることとなる。ワイヤー２１は工具保持紐３０と同じ材質の紐体から構成してよく、その場合、ナスカン２２と緩衝器２３とを除去して、接続部材と工具保持体とは単一の紐体で構成してもよい。工具保持体は工具を保持できればよく、紐体でなくともよい。例えば、工具に二重リングが取り付けられている場合、この二重リングとナスカン２２と接続して、ナスカン２２を工具保持体として機能させてもよい。この場合、リング１３、二重リング２４、リール２０、ワイヤー２１及び緩衝器２３を接続部材とすることができる。 The tool holding string 30 is a string body having a ring 31a formed at the tip, and is formed in a “6” shape through the base end of the ring 31a at the tip. The tool holding string 30 serves as a tool holder. As a result, a ring-shaped holding portion 31 for fixing the tool, which can be changed in size at the tip position, is formed. The wire 21 may be composed of a string body made of the same material as that of the tool holding string 30. In this case, the connecting member and the tool holding body are formed of a single string body by removing the eggplant 22 and the shock absorber 23. May be. The tool holder need only hold the tool, and need not be a string. For example, when a double ring is attached to the tool, the double ring and the eggplant 22 may be connected to cause the eggplant 22 to function as a tool holder. In this case, the ring 13, the double ring 24, the reel 20, the wire 21, and the shock absorber 23 can be used as connection members.
　リング状保持部３１が形成された状態において、先端の輪３１ａよりも基端側には筒状のストッパー３２が通される。ストッパー３２は使用者が手で持ってスライドすることができるが、下方から先端の輪３１ａによって押し上げられても摩擦で動かないように形成されており、ストッパー３２の位置を調節することで、リング状保持部３１のリングの大きさを規定することができる。工具保持紐３０の基端にはリング体が固定され、当該リング体はリール２０のワイヤー２１先端に設けられるナスカン２２に固定される。工具保持紐３０は金属ワイヤーの回りを合成樹脂で覆うことで外表面が滑りにくく形成されている。 In the state where the ring-shaped holding portion 31 is formed, a cylindrical stopper 32 is passed through the base end side of the tip ring 31a. The stopper 32 can be held and slid by the user by hand, but is formed so as not to move by friction even when pushed up by the ring 31a at the tip from below. By adjusting the position of the stopper 32, the ring The size of the ring of the shape holding part 31 can be defined. A ring body is fixed to the proximal end of the tool holding string 30, and the ring body is fixed to an eggplant 22 provided at the tip of the wire 21 of the reel 20. The tool holding string 30 is formed so that the outer surface is hard to slip by covering the metal wire with a synthetic resin.
　図２に工具落下防止具Ｘの一部を構成する腰ベルトＸ2の斜視図を示す。腰ベルトＸ2は、一般的なズボンの腰周りに固定される作業用ベルト５０と、作業用ベルト５０に摺動可能に吊り下げられるＪ字状のフック６０とから構成される。フック６０は工具掛け具となる。工具掛け具の形状はＪ字状に限定されず、工具の種類によって適宜設定される。フック６０は鉛直軸及び水平軸周りに回転可能に吊り下げられる。 FIG. 2 shows a perspective view of a waist belt X2 constituting a part of the tool fall prevention tool X. As shown in FIG. The waist belt X2 is composed of a working belt 50 fixed around the waist of a general trouser and a J-shaped hook 60 suspended slidably on the working belt 50. The hook 60 serves as a tool hanging tool. The shape of the tool hanging tool is not limited to a J-shape, and is appropriately set depending on the type of tool. The hook 60 is suspended so as to be rotatable about a vertical axis and a horizontal axis.
　次に以上のような構成を有する工具落下防止具Ｘの使用方法について説明する。なお、図３～図５では右利きの利用者の例を示しているが、左利きの利用者も左右を逆にすれば同様に工具落下防止具Ｘを利用することができる。
　まず、使用者は、工具落下防止具Ｘの工具保持紐３０に重量のある電動ドリルなどの工具を固定する。固定の方法は、工具保持紐３０のリング状保持部３１のリングに工具を通して、当該リングを締め付けた後にストッパー３２をずらして当該リングが広がらないように固定する。なお、工具のハンドル部分が閉じた輪を形成している場合に、このハンドル部分の輪に固定するには、工具保持紐３０をワイヤー２１のナスカン２２から外して、ストッパー３２と先端の輪３１ａを基端から抜き、その後、この先端の輪３１ａを工具のハンドル部分の輪に通してから再び基端から挿入し、さらにストッパー３２を通してから、再びナスカン２２に工具保持紐３０を固定するようにすればよい。また、工具にストラップなどを固定するリングが固定されている場合には、工具保持紐３０は取り外して、当該リングをワイヤー２１先端のナスカン２２に固定するようにすればよい。 Next, the usage method of the tool fall prevention tool X which has the above structures is demonstrated. 3 to 5 show an example of a right-handed user, but a left-handed user can similarly use the tool fall prevention tool X if the left and right are reversed.
First, the user fixes a heavy tool such as an electric drill to the tool holding string 30 of the tool fall prevention tool X. As a fixing method, a tool is passed through the ring of the ring-shaped holding portion 31 of the tool holding string 30 and, after tightening the ring, the stopper 32 is shifted and fixed so that the ring does not spread. When the handle portion of the tool forms a closed ring, in order to fix the wheel to the handle portion, the tool holding strap 30 is removed from the eggplant 22 of the wire 21, and the stopper 32 and the tip ring 31a are removed. So that the ring 31a at the tip is passed through the ring at the handle portion of the tool and then inserted again from the base end. Further, after passing through the stopper 32, the tool holding string 30 is fixed to the NASKAN 22 again. do it. Further, when a ring for fixing a strap or the like is fixed to the tool, the tool holding string 30 may be removed and the ring may be fixed to the eggplant 22 at the tip of the wire 21.
　次に、工具落下防止具Ｘの肩掛けベルト１０を肩から掛け、送りカン１２の位置を調節することでしっかりと締め付けて固定する。この際、図３に示すように肩パッド１１は、肩掛けベルト１０が脇の下を通り、使用者の一方の肩の範囲Ｌ３に当接するように、その肩の上に設けられる。範囲Ｌ３の長さは一方の肩の長さとなる。脇の下を通り、肩の範囲Ｌ３に収まるように肩に当接される、肩掛けベルト１０は、脇の下から首の付け根までの範囲（下限の範囲となる）Ｌ１と、脇の下から肩の先端までの範囲（上限の範囲となる）Ｌ２との間に収まる。肩掛けベルト１０が範囲Ｌ１と範囲Ｌ２との間に収まると、肩掛けベルト１０が肩から脱落しなくなる。肩掛けベルト１０の長さは、肩掛けベルト１０が範囲Ｌ１と範囲Ｌ２との間に収まるように、送りカン１２で調整可能な長さがあればよい。肩掛けベルト１０を脇の下から肩の先端までの範囲Ｌ２を通るようにすると、肩掛けベルト１０が移動して首の付け根を通るようになっても、肩掛けベルト１０が下がる下端は脇の下から距離ｍの位置に収まる。この距離ｍは範囲Ｌ３の長さ、すなわち一方の肩の長さとなる。よって、肩掛けベルト１０の下端の位置も規定されることになる。図３の破線で示す範囲は、首の付け根と、肩掛けベルト１０が下がる下端との間の範囲を示す。 Next, the shoulder belt 10 of the tool fall prevention tool X is hung from the shoulder, and the position of the feed can 12 is adjusted and firmly tightened and fixed. At this time, as shown in FIG. 3, the shoulder pad 11 is provided on the shoulder so that the shoulder belt 10 passes under the armpit and comes into contact with the range L3 of one shoulder of the user. The length of the range L3 is the length of one shoulder. The shoulder belt 10 that passes through the armpit and abuts against the shoulder so as to be within the shoulder range L3 is a range from the armpit to the base of the neck (the lower limit range) L1, and a range from the armpit to the shoulder tip. It falls within L2 (which is the upper limit range). When the shoulder belt 10 fits between the range L1 and the range L2, the shoulder belt 10 does not fall off from the shoulder. The length of the shoulder belt 10 only needs to be adjustable by the feed can 12 so that the shoulder belt 10 falls within the range L1 and the range L2. When the shoulder belt 10 passes through the range L2 from the armpit to the shoulder tip, even if the shoulder belt 10 moves and passes through the base of the neck, the lower end at which the shoulder belt 10 is lowered is located at a distance m from the armpit. Fits in. This distance m is the length of the range L3, that is, the length of one shoulder. Therefore, the position of the lower end of the shoulder belt 10 is also defined. A range indicated by a broken line in FIG. 3 indicates a range between the base of the neck and the lower end where the shoulder belt 10 is lowered.
　リール２０は上端が肩の反対側の脇の下又は脇の下から距離ｍの位置までの間に位置するようにする。そして、リール２０が脇の下から距離ｍの位置の範囲で肩掛けベルト１０に接続されるようにする。リール２０が設けられない場合には接続部材の端部が肩の反対側の脇の下又は脇の下から距離ｍの位置までの間に位置するようにする。なお、リール２０は接続部材の端部に配置されていなくともよい。リール２０の大きさによっては、リール２０の上端が脇の下又は脇の下から距離ｍの位置までの間に配置されると、腕の動きの邪魔になる場合があり、その場合には脇の下から距離ｍの位置より下の位置に配置される方が好ましい場合がある。リール２０と肩掛けベルト１０の下端とを紐体で接続し、リール２０を脇の下から距離ｍの位置より下の位置に配置することができる。 The reel 20 is positioned so that the upper end is located between the armpit opposite the shoulder or between the armpit and the distance m. The reel 20 is connected to the shoulder belt 10 within a range of a distance m from the armpit. When the reel 20 is not provided, the end of the connecting member is positioned between the armpit opposite the shoulder or between the armpit and the position of the distance m. Note that the reel 20 may not be disposed at the end of the connection member. Depending on the size of the reel 20, if the upper end of the reel 20 is arranged between the armpit or the armpit and a position at a distance m, it may interfere with the movement of the arm. In some cases, it is preferable to arrange the position below the position. The reel 20 and the lower end of the shoulder belt 10 can be connected by a string, and the reel 20 can be arranged at a position below the position m from the armpit.
　図４に示すように、リール２０及びワイヤー２１は、使用者の身体の側面の中心線上又は近傍に配置される。リール２０を設けない場合にはワイヤー２１の端部が使用者の身体の側面の中心線上又は近傍に配置される。近傍とは、例えば、上腕部の幅をＴとすると、中心線から左右方向にそれぞれＴ／２の範囲である。こうすることで、荷重が身体の中心又はほぼ中心に掛かるので、荷重によって身体に不要なトルクがかかることがなくなる。
　また、腰には腰ベルトＸ2を固定する。その後、リール２０中央のボタンを押してワイヤー２１を開放し、工具が腰ベルトＸ2のフック６０に掛かるようにワイヤー２１の繰出し長さを調整して、工具を腰ベルトＸ2に引っ掛けるようにする。以上で、工具落下防止具Ｘの装着が完了する。図５に工具を固定した工具保持具Ｘの装着状態を表す斜視図を示す。なお、工具落下防止具Ｘは腰ベルトＸ2とともに用いなくともよく、図１に示す工具落下防止具Ｘの主要部分を単独で用いてもよい。 As shown in FIG. 4, the reel 20 and the wire 21 are disposed on or near the center line of the side surface of the user's body. When the reel 20 is not provided, the end of the wire 21 is disposed on or near the center line of the side surface of the user's body. The neighborhood is, for example, a range of T / 2 in the horizontal direction from the center line, where T is the width of the upper arm. By doing so, since the load is applied to the center of the body or almost at the center, unnecessary torque is not applied to the body by the load.
A waist belt X2 is fixed to the waist. Thereafter, the button at the center of the reel 20 is pressed to release the wire 21, the feeding length of the wire 21 is adjusted so that the tool is hooked on the hook 60 of the waist belt X 2, and the tool is hooked on the waist belt X 2. This completes the mounting of the tool fall prevention tool X. FIG. 5 is a perspective view showing a mounting state of the tool holder X to which the tool is fixed. The tool fall prevention tool X may not be used together with the waist belt X2, and the main part of the tool fall prevention tool X shown in FIG. 1 may be used alone.
　使用者は、この状態で作業位置に移動して、必要に応じて工具Ｔを手に持ち、フック６０から外して作業を行なう。なお、作業に際しては必要に応じて、リール２０中央のボタンを押してワイヤー２１を巻き取るボビンをロック状態から開放して、作業しやすいように繰出し量を調節し、その後リール２０中央のボタンを押して再びロックするようにすることができる。 In this state, the user moves to the work position, holds the tool T in his hand as necessary, and removes the hook 60 to work. When working, if necessary, press the button at the center of the reel 20 to release the bobbin that winds the wire 21 from the locked state, adjust the feeding amount so that it is easy to work, and then press the button at the center of the reel 20. It can be locked again.
　本実施形態に係る工具落下防止具Ｘは、上記の構成、使用方法によって、使用者の移動時にフック６０から工具が脱落したり、作業時に手が滑って工具が落下しても、工具Ｔはワイヤー２１を介して肩掛けベルト１０に固定されているので、地面まで落下することを防ぐことができる。また、ワイヤー２１の先端に引っ張りばねからなる緩衝器２３が設けられているので、落下の衝撃が緩衝器２３が伸びることで吸収され使用者に工具の落下による強い衝撃が加わることを緩和することができ、また、これによって落下の衝撃を受けて使用者がバランスを崩すことを抑制することができる。そして、工具保持具Ｘは肩掛けベルト１０がぴったりと体に密着して、たるみがないため、移動時や作業時に出っ張りや物に引っ掛かりにくく、また、肩からずり下がることがない。 The tool fall prevention tool X according to this embodiment has the above-described configuration and method of use. Even if the tool falls off the hook 60 when the user moves or the tool slips when the user moves, the tool T Since it is being fixed to the shoulder belt 10 via the wire 21, it can prevent falling to the ground. Further, since the shock absorber 23 made of a tension spring is provided at the tip of the wire 21, the impact of the fall is absorbed by the extension of the shock absorber 23, and the user is prevented from receiving a strong impact due to the fall of the tool. In addition, the user can be prevented from being out of balance due to the impact of dropping. The tool holder X has the shoulder belt 10 in close contact with the body and has no slack. Therefore, the tool holder X is not easily caught on a ledge or object during movement or work, and does not slide down from the shoulder.
　なお、上記実施形態では、シート部材として、一方の肩から他方の脇の下を通るリング状の肩掛けベルトを示したが、脇の下にリール等を固定でき、使用者の体に密着固定できる形態のものであれば種々のものを採用できる。
　また、上記形態では、緩衝器を引っ張りばねとしているが、ワイヤー２１の一部又は前部を伸縉哇のある弾性体により形成することで緩衝器とすることもできる。
　さらに、工具を固定するための工具保持紐３０の形状も例示であり、帯状として面ファスナーを用いて固定可能としたり、先端の輪の部分をナスカン等にしたり等適宜変更が可能である。 In the above embodiment, a ring-shaped shoulder belt that passes from one shoulder to the other armpit is shown as the seat member. However, a reel or the like can be fixed to the armpit, and the seat member can be tightly fixed to the user's body. If there are various things, it can employ | adopt.
Moreover, in the said form, although the shock absorber is made into the tension spring, it can also be set as a shock absorber by forming a part or front part of the wire 21 with the elastic body with extension.
Furthermore, the shape of the tool holding string 30 for fixing the tool is also an example, and can be appropriately changed such as being able to be fixed using a hook-and-loop fastener as a belt shape, or changing the ring portion at the tip to an eggplant or the like.
　本実施形態によれば、次のような効果を奏する。
　シート部材のリング状部分は、使用者の一方の肩と、当該肩の反対側の脇の下から、該脇の下から前記肩の長さ分下の位置までの範囲とを通るので、使用者の体に、より密着し、これによりシート部材が物等に引っかかることを低減することができる。そして、工具を先端に固定する接続部材は工具を持つ間は、脇の下かそれより肩の長さ分低い位置を支点として腕に沿って動くので、従来のものに比較してやはり物等に引っかかりにくい。さらに、シート部材が、シート部材が肩から脱落することも抑制される。 According to the present embodiment, the following effects can be obtained.
The ring-shaped portion of the seat member passes through one shoulder of the user and the range from the armpit opposite to the shoulder to the position below the length of the shoulder from the armpit. Thus, it is possible to reduce contact between the sheet member and the object. The connecting member that fixes the tool to the tip moves along the arm with the armpit or lower shoulder length as a fulcrum while holding the tool. Hateful. Furthermore, the sheet member is also prevented from dropping off from the shoulder.
　また、シート部材をベルト状としてリング状部分の周の長さを調節可能に形成することで、シート部材を使用者の体の大きさに合わせてぴったりと密着させることができ、さらに、物等へ引っかかる可能性を低減することができる。
　また、工具を先端に固定する紐体をリールから任意の繰り出し位置で固定できるので、運搬時や作業時に最も紐体がたるまないような長さに調節することで、状況に応じて物等に引っかかる可能性を抑制することができる。 In addition, by forming the seat member in a belt shape so that the circumferential length of the ring-shaped portion can be adjusted, the seat member can be closely adhered to the size of the user's body. The possibility of catching on can be reduced.
In addition, since the string body that fixes the tool to the tip can be fixed from the reel at an arbitrary feeding position, by adjusting the length so that the string body does not sag the most during transportation or work, The possibility of being caught can be suppressed.
　また、工具を腰のフックに引っ掛けることが可能となり、工具落下防止具に固定した工具を使用しないときに、当該工具を保持させことで使用者の手を自由にすることができる。
　また、緩衝器を設けることで、工具の落下時の衝撃を抑制することができる。 In addition, the tool can be hooked on the waist hook, and when the tool fixed to the tool fall prevention tool is not used, the user's hand can be freed by holding the tool.
Moreover, the shock at the time of the fall of a tool can be suppressed by providing a buffer.
　さらに、工具が仮に落下した場合、脇下とは反対の方の肩で落下による衝撃を緩衝できる。そのため、工具が電動ドリルのように重くても、使用者の身体が大きく振られることがなく、両足で踏ん張ることが出来る。 Furthermore, if the tool falls, the impact caused by the fall can be buffered by the shoulder opposite to the armpit. Therefore, even if the tool is heavy like an electric drill, the user's body is not greatly shaken and can be strung with both feet.
　以上、本発明の代表的な各実施形態について説明したが、本発明は、本願の請求の範囲によって規定される、その精神または主要な特徴から逸脱することなく、他の種々の形で実施することができる。そのため、前述した各実施形態は単なる例示にすぎず、限定的に解釈されるべきではない。本発明の範囲は特許請求の範囲によって示すものであって、明細書や要約書の記載には拘束されない。さらに、特許請求の範囲の均等範囲に属する変形や変更はすべて本発明の範囲内のものである。 While typical embodiments of the present invention have been described above, the present invention can be implemented in various other forms without departing from the spirit or main features defined by the claims of the present application. be able to.
