Description
【考案の詳細な説明】 本考案は走行手段を有する鋏に関する。[Detailed explanation of the idea] The present invention relates to scissors with running means.
従来の鋏は、刃部を一端に、柄部を他端に有する一対の
部材を互いに交叉するように枢着して構成しである。Conventional scissors are constructed by pivoting a pair of members having a blade portion at one end and a handle portion at the other end so as to intersect with each other.
従って、紙又は鉄板等(以下鉄板と総称する)を切断す
る場合に、柄部を握る手首が鋏を進行させる際に鉄板の
切口につき当ってしまうので、さらに切断を進行させる
には、二つに分れた鉄板の一つを上方に持ち上げ、他の
一つを下方に押し下げて手首の進行を妨げないようにす
る必要がある。Therefore, when cutting paper or an iron plate (hereinafter collectively referred to as the iron plate), the wrist that grips the handle will hit the cut end of the iron plate when advancing the scissors, so in order to proceed with the cutting further, there are two It is necessary to lift one of the two metal plates upward and push the other downward so as not to impede the movement of the wrist.
しかしながら、鉄板の厚さが厚い場合には前記のように
切口を境に一つは上方に、他の一つは下方に撓ませるこ
とは困難になり、無理にすれば塑性変形を起してしまっ
て切断後が凸凹状となる。However, if the steel plate is thick, it will be difficult to bend one side upward and the other downward across the cut as described above, and if you force it, plastic deformation will occur. If it is stored away, the cut surface will be uneven.
また手首は常に鋭利な切口に接触する危険にさらされて
おり、かかる切断作業中に負傷することは日常経験する
ことである。The wrist is also constantly at risk of coming into contact with sharp cuts, and injuries during such cutting operations are common.
殊に、厚手の鉄板で切断方向を変えようとする場合は前
記の困難と危険とは更に倍加する。In particular, when attempting to change the cutting direction of a thick steel plate, the above-mentioned difficulties and dangers are further compounded.
走行手段を備え、平面上を走行しながら被切断物の荷重
を走行手段で支えさせることにより、切断作業の疲労の
軽減化を図った鋏は既に知られている。2. Description of the Related Art Scissors are already known which are equipped with a traveling means and which support the load of an object to be cut while traveling on a flat surface, thereby reducing fatigue during cutting operations.
しかし、従来品は下刃の前端にのみ車輪を備えたもので
あって、鋏の切断作業は従来と同様に、上・下各刃の後
端を指で支持して拡縮運動することにより行なうもので
あるから、切断工程中は常に鋏を手で持っている必要が
あり、途中で手を放すと、被切断物が鉄板のような硬い
ものである場合は、鋏が倒れた際に、刃が破壊されたり
、枢軸にがたが生じる欠点があり、さらに大きな問題は
車輪が上刃と下刃の枢着点よりも前端に設けられている
から、被切断物の切断中は直進しかできないこと、つま
り車輪よりも後方の位置で切断する際は切断方向を変え
ることができないことである。However, conventional products are equipped with wheels only at the front end of the lower blade, and cutting work with the scissors is performed by supporting the rear ends of the upper and lower blades with your fingers and expanding and contracting them, as in the past. Because it is a metal object, it is necessary to hold the scissors in your hand at all times during the cutting process. There is a drawback that the blade may be destroyed or the pivot may rattle.An even bigger problem is that the wheels are located at the front end of the pivot point of the upper and lower blades, so while cutting the object, the wheels can only move straight. In other words, when cutting at a position behind the wheels, the cutting direction cannot be changed.
本考案は、被切断物を静置したまま迅速・円滑に切断で
きるとともに、切断後の切口が手首に接触せずに安全に
切断でき、とくに、切断中に切断方向を容易に変えられ
る鋏を提供することを目的とする。This invention uses scissors that can quickly and smoothly cut the object while it remains still, can cut safely without the cut end coming into contact with the wrist, and in particular, can easily change the cutting direction while cutting. The purpose is to provide.

作用を行なうようになっている。Since both the upper blade 2a and the end portion 2b of the upper body 2 are located above the lower body 1 in the figure, the end portion 2b of the upper body 2
When the upper blade 2a is pushed upward in the figure, the upper blade 2a swings downward to perform a scissoring action.
リンク7は両端にネジ9,10を遊嵌する孔が穿設され
た部材で、押手6に加える力を上部本体に伝達する役目
を有している。The link 7 is a member having holes at both ends into which screws 9 and 10 are loosely fitted, and has the role of transmitting the force applied to the pusher 6 to the upper body.
押手6は一端6aにリンク7を枢支するネジ10が螺着
され、他端6bは手で把持し易い形状に曲げられており
、ネジ10のネジ孔の近傍に、下部本体1の突縁1bに
枢支するネジ11のネジ孔が形成されている。A screw 10 for pivotally supporting the link 7 is screwed onto one end 6a of the pusher 6, and the other end 6b is bent into a shape that is easy to hold by hand. A screw hole for a screw 11 that is pivotally supported in 1b is formed.
また、この実施例では、上部本体2の端部2bと下部本
体1との間に引張りバネ14が装着されており、刃を常

6の端部6b(把持部となる)が常時持上げられている
ようになっている。Further, in this embodiment, a tension spring 14 is installed between the end 2b of the upper main body 2 and the lower main body 1, and urges the blade to open at all times. The portion 6b (which becomes the gripping portion) is always lifted.
以上のように構成された鋏を俵用するには、まず鉄板を
切断開始点において上刃2a、下刃1aとの・間に挾む
。To use the scissors constructed as described above for cutting bales, first, an iron plate is placed between the upper blade 2a and the lower blade 1a at the cutting starting point.
このとき、引張りバネ14の力によって上刃2aは押上
げられて常時刃が開口しているから、容易に切断開始点
にセットすることができる。At this time, the upper blade 2a is pushed up by the force of the tension spring 14 and the blade is always open, so that it can be easily set at the cutting starting point.
そして、同様にして、押手6の端部6bは常時挙上状態
にあるから、直ちに手で端部6bを押下すれば、鉄板は
鋏作用を受けて切断される。Similarly, since the end 6b of the pusher 6 is always in a raised state, if the end 6b is immediately pushed down by hand, the iron plate will be cut by the action of the scissors.
切断後、押手6にかかる押圧力を除去すれば、バネ14
の力により押手6は自動的に押し上げられるから、従来
の金鉄を使用する際に上下動させる労力と煩わしさがな
くなる。After cutting, if the pressing force applied to the pusher 6 is removed, the spring 14
Since the pusher 6 is automatically pushed up by the force of , the effort and trouble of moving it up and down when using conventional metal iron is eliminated.
次に、切断による切れ目が生じているから、この切れ目
(隙間)に刃部を更に深く進入させる。Next, since there is a cut caused by the cutting, the blade part is inserted deeper into this cut (gap).
この際、本考案の鋏の下部本体には走行手段を有するか
ら、押手6のみを把持して鋏を前進させるだけでよく、
また切断されて左右に分れた鉄板は刃部より進行方向遅
れ側において自重により走行面15まで降下するが、把
持している手首は常に走行面15より上方において上下
動しているから、鉄板の切口に突き当たることはない。At this time, since the lower body of the scissors of the present invention has a traveling means, it is only necessary to hold the pusher 6 and move the scissors forward.
In addition, the cut iron plate divided into left and right parts falls to the running surface 15 due to its own weight on the side that lags behind the blade, but since the wrist that is gripping it is always moving up and down above the running surface 15, the iron plate You will never run into a cut.
従って、分れた鉄板の一つは上方に、他の一つは下方に
押下げながら鋏を進行させるような煩わしさがなく、殊
にこのように撓ませることが困難で、無理にすると塑性
変形を起し易い厚手の鉄板を切断する場合に極めて有効
であって、安全かつ迅速に切断作業が可能となる。Therefore, there is no need to move the scissors while pressing one of the separated iron plates upward and the other downward. It is extremely effective when cutting thick iron plates that are prone to deformation, and allows safe and quick cutting work.
次に、途中で切断方向を変化させる場合は、押手6を切
断方向と反対側に寄せれば、噛合い点を中心として押下
6は手の側柱方向に移動するが、本考案の鋏の下部には
前輪3と台車4とが取付けられてあり、前輪3は方向随
意性がすぐれており、台車4も第2図によく示されるよ
うに、中央部は下部本体1と回転自在に枢支されて(符
号16)、2点鎖線で示すように方向が変えられるので
、容易に切断方向の変換が可能である。Next, when changing the cutting direction midway through, if the pusher 6 is moved to the opposite side of the cutting direction, the pusher 6 moves toward the side column of the hand centering on the engagement point, but the scissors of the present invention A front wheel 3 and a truck 4 are attached to the lower part, and the front wheel 3 has excellent directional flexibility, and the center part of the truck 4 is rotatably connected to the lower body 1, as shown in FIG. Since the cutting direction can be changed as shown by the two-dot chain line, the cutting direction can be easily changed.

前輪3と共働して鋏全体の転倒を防止し、安定して切断
作業及び方向変換ができるのである。Also, since the truck has two left and right rear wheels 12.13,
It works together with the front wheel 3 to prevent the entire scissors from tipping over, allowing stable cutting operations and direction changes.
上述の実施例ではバネ14を上部本体2の端部2bと下
部本体1との間に介在せしめたが、勿論、バネは必ずし
も必要ではない。In the above-described embodiment, the spring 14 is interposed between the end 2b of the upper body 2 and the lower body 1, but of course the spring is not always necessary.
むしろ、微妙な切断作業を要求する場合はバネはない方
がよい。In fact, if delicate cutting work is required, it is better not to have a spring.
次に、バネ14を上述の実施例のように介在させ、リン
ク7を除去して上部本体2の端部2bを直接、押手の一
端6aに常時当接させてもよい。Next, the spring 14 may be interposed as in the above embodiment, the link 7 may be removed, and the end 2b of the upper body 2 may be brought into direct contact with the one end 6a of the pusher at all times.
但しこの場合、摩擦抵抗を減少させ耐久性を増大させる
ために、押手の一端6aにコロを配設させ、コロの転勤
面と上部本体2の端部2bとを当接させるのが好ましい
。However, in this case, in order to reduce frictional resistance and increase durability, it is preferable to arrange a roller at one end 6a of the pusher and to bring the rolling surface of the roller into contact with the end 2b of the upper body 2.
本考案の鋏は紙、金属板に限らず、大きな面積を有する
布地の切断にも有効、使用可能であることは勿論である
