Description

曲線剪刀Curve Scissors

本創作涉及一種剪刀，尤指一種省力、防滑、輕鬆使用且能提高剪切效果的曲線剪刀。This creation relates to a pair of scissors, especially a curved scissors that is labor-saving, non-slip, easy to use and can improve the cutting effect.

剪刀為日常生活中不可或缺的手工具之一，透過剪刀的使用，讓使用者可以對於物件進行剪斷、裁切或修整等操作，其中可依據使用的領域分為醫療手術、一般辦公、植物修剪、裁縫使用等不同類型的剪刀。Scissors are one of the indispensable hand tools in daily life. Through the use of scissors, users can cut, trim or trim objects. Among them, they can be divided into medical surgery, general office, Plant trimming, tailoring and other different types of scissors.

現有剪刀如台灣發明專利第I608914號所揭示的辦公用剪刀，其雖可透過刃體部呈圓弧狀彎曲，刀刃基部內縮而形成階差部，刃體部背面形成沿著彎曲刀刃之彎曲面槽，達到容易切斷物件且防止黏膠於剪切過程中附著於刀刃上的效果，但刀刃頂端的開口角度略小，在進行剪切時必須施以較大的力量將握柄張開較大的幅度，方能讓現有剪刀於兩刀刃頂端的內側面之間具有一大開口，對於使用者而言較為費力，且當使用者長時間反覆開合握柄進行剪切時，會容易因過度費力而使手部產生疲勞或痠痛現象，增加使用上的不便。Existing scissors, such as the office scissors disclosed in Taiwan Invention Patent No. I608914, although they can be curved in an arc through the blade body, the blade base shrinks to form a stepped portion, and the back of the blade body forms a curve along the curved blade The face groove achieves the effect of easily cutting the object and preventing the glue from adhering to the blade during the cutting process, but the opening angle of the tip of the blade is slightly smaller, and a large force must be applied to open the handle when cutting The larger range allows the existing scissors to have a large opening between the inner sides of the tops of the two blades, which is more laborious for the user, and when the user repeatedly opens and closes the handle to cut for a long time, it will be easy Excessive effort may cause fatigue or soreness in the hands, increasing the inconvenience in use.

進一步，現有剪刀的兩刀刃內側面由前端至後端為一連續的弧形曲線，因為兩刀刃後端相交處因弧形曲線而呈極小剪切開口，雖然可省力地剪切厚度較薄的紙張或其他物件，但現有剪刀的兩刀刃內側面於後端處較寬，當欲對於較厚的紙張或厚硬材質的物件（尤其是棒狀物體）進行剪切時，可能會往刀刃頂端滑動，致使剪切力大減，而需花費相當或更大的力氣才能完成剪切的作業，使用上相對不輕鬆，對於需長時間反覆做剪切的使用者而言，手部容易產生疲勞或痠痛；綜上所述，現有剪刀存在有前述兩刀刃前端之間的開口小以及兩刀刃後端之間的剪切力量有限的現象，導致現有剪刀於使用上費力以及無法輕鬆剪切厚硬材質物件之問題，實有需要加以改進之處。Further, the inner side of the two blades of the existing scissors is a continuous arc curve from the front end to the rear end, because the intersection of the two blades at the rear end has a very small shear opening due to the arc curve, although it can cut thinner Paper or other objects, but the inner side of the two blades of the existing scissors is wider at the rear end. When you want to cut thick paper or hard objects (especially rod-shaped objects), you may go to the top of the blade Sliding, which greatly reduces the shearing force, and requires considerable or more effort to complete the shearing operation. It is relatively difficult to use. For users who need to repeatedly cut for a long time, the hands are prone to fatigue Or sore; in summary, the existing scissors have the phenomenon that the opening between the front ends of the two blades is small and the cutting force between the rear ends of the two blades is limited, which makes the existing scissors laborious and difficult to cut thick and hard The problem of material objects really needs to be improved.

因此，本創作有鑑於現有剪刀於實際使用時，因兩刀刃前端之間的開口小以及兩刀刃後端之間的剪切力量有限的現象，導致現有剪刀於使用上費力以及無法輕鬆剪切厚硬材質物件的缺失及不足，特經過不斷的試驗與研究，終於發展出一種能改進現有缺失之本創作，本創作的曲線剪刀，主要係透過精簡的結構配置方式，於使用時不僅能藉由小幅度開合兩握柄的方式，即能讓兩刀刃前端部之間具有大角度的開口，進而能輕鬆且省力地完成精細剪切，並且能藉由兩刀刃後半部的結構設置方式，以較小的施力達成剪切厚硬材質之效果，大幅提升兩刀刃的剪切力量，有效改善現有剪刀具有費力且無法輕鬆剪切厚硬材質物件之問題，藉以提供一省力、防滑、輕鬆使用且能提高剪切效果的曲線剪刀之目的。Therefore, in this creation, in view of the actual use of the existing scissors, due to the small opening between the front ends of the two blades and the limited shearing force between the rear ends of the two blades, the existing scissors are laborious to use and cannot easily cut thick The lack and insufficiency of hard material objects, after continuous experimentation and research, finally developed a kind of original creation that can improve the existing lack. The curved scissors of this creation are mainly through a simplified structure configuration method, which can not only be used by The way of opening and closing the two grips by a small amount allows a large angle opening between the front ends of the two blades, which can easily and finely complete fine cutting, and can be set by the structure of the second half of the two blades. The smaller force exerts the effect of cutting thick and hard materials, greatly increasing the cutting force of the two blades, and effectively improves the problem that the existing scissors are laborious and cannot cut thick and hard materials easily, thereby providing a labor-saving, non-slip, easy to use And the purpose of curve scissors that can improve the cutting effect.

再請進一步參看如圖10、11a及圖11b所示之本創作曲線剪刀的第三較佳實施例，該第三較佳施例與第一較佳實施例的結構相近似，其差異在於：各刀刃部13B在該第二曲線152B處的刀刃斜面之傾斜角度θ2較在該第一曲線151B處之傾斜角度θ1小，即θ2>θ1，使該第二曲線152B的刀刃部13B更為銳利，可增加該兩刀刃部13B的剪切力。Please further refer to the third preferred embodiment of the original curved scissors shown in FIGS. 10, 11a and 11b. The third preferred embodiment is similar in structure to the first preferred embodiment, and the differences are as follows: The inclination angle θ2 of the blade slope at the second curve 152B of each blade portion 13B is smaller than the inclination angle θ1 at the first curve 151B, that is, θ2>θ1, making the blade portion 13B of the second curve 152B sharper , The shearing force of the two blade portions 13B can be increased.

藉由上述的技術手段，本創作的曲線剪刀透過於各刀刃部13的剪切刃15設置至少一曲線組的設置方式，不僅能透過位於該兩刀刃部13前半部朝內側彎曲的該兩第一曲線151、151A、151B，讓使用者能藉由小幅度將該兩握柄21開啟後，即可在該兩刀刃部13、13A、13B的前半部之間形成大開口角度，透過波浪狀曲線的兩剪切刃15、15A輕鬆且省力地完成精細剪切，並且能透過位於該兩刀刃部13、13A、13B後半部的朝外側彎曲的該兩第二曲線152、152A、152B，讓使用者在剪切厚硬材質的待剪物件40或圓形棒狀物件50時，該厚硬材質的待剪物件40或圓形棒狀物件50可被稍微鉗制於該兩刀刃部13、13A、13B的該兩第二曲線152、152A、152B處而不易產生滑動，不會因滑動而影響剪切力，讓使用者不需花費額外的力氣即可輕鬆地進行剪切，使用上相對方便且實用，有效避免因過度費力而使手部產生疲勞或痠痛現象，藉以提供一省力、防滑、輕鬆使用且能提高剪切效果的曲線剪刀。By the above-mentioned technical means, the curvilinear scissors of the present invention are provided with at least one curvilinear group through the cutting edge 15 of each blade 13, and not only can the two scissors located at the front half of the two blades 13 bend inward A curve 151, 151A, 151B allows the user to open the two grips 21 by a small amount, and then a large opening angle can be formed between the front halves of the two blade portions 13, 13A, 13B, through the wavy shape The two cutting edges 15, 15A of the curve perform fine cutting easily and effortlessly, and can pass through the two second curves 152, 152A, 152B, which are outwardly bent at the rear half of the two blade portions 13, 13A, 13B, to let When the user cuts the thick and hard material to be cut 40 or the round rod-shaped object 50, the thick and hard material to be cut 40 or the round rod-shaped object 50 can be slightly clamped on the two blade portions 13, 13A 13B, the two second curves 152, 152A, 152B are not easy to slide, and the shear force will not be affected by the sliding, so that the user can easily cut without extra effort, which is relatively convenient to use It is practical and effectively avoids fatigue or soreness caused by excessive effort, thereby providing a curved scissors that is labor-saving, non-slip, easy to use, and can improve the cutting effect.
