Description

FIELD OF THE INVENTION

[0001] The present invention relates to scissors to be comfortably used by hand, and more particularly, to scissors to be comfortably used by hand that can minimize pain in fingers and wrist when scissoring.BACKGROUND OF THE INVENTION

[0002] Generally, scissors are used to cut objects to be cut (things, food ingredients, hair, etc.) and are classified into industrial scissors for cutting things, kitchen scissors for cutting food ingredients, cosmetic scissors for cutting hair, etc.

[0003] Such scissors include a first rotating body having a first cutting blade and a first finger insertion portion provided at the front and rear thereof, respectively, and a second rotating body connected to the first rotating body to be rotatable relative to the first rotating body about a hinge shaft and having a second cutting blade and a second finger insertion portion provided at the front and rear thereof, respectively, and an insertion hole is formed in each of the first finger insertion portion and the second finger insertion portion for a user to insert his or her fingers.

[0004] However, since the conventional scissors have a structure in which a user's thumb is inserted through the insertion hole in a diagonal direction, pain may be caused during scissoring due to an inner circumferential surface of the insertion hole and a circumference of the thumb coming in contact with a strong pressure. Also, since the user's wrist is also twisted in a direction in which the thumb is inserted, wrist pain may be caused when the scissors are used for a long time, and since a length at which the thumb is inserted is short, in many cases, the thumb falls out of the insertion hole during scissoring.

[0005] An example of the related art of the present invention includes Korean Utility Model Application Publication No. 1 0-2022-0028423 (Date of Publication: March 08, 2022), which discloses scissors for cooking.OBJECT OF THE INVENTION

[0006] The present invention is directed to providing scissors to be comfortably used by hand that can minimize pain in fingers and wrist when scissoring.SUMMARY OF THE INVENTION

[0008] Also, the rear end of the second blade portion may be coupled to a lower region of the second holding tool based on the second finger insertion hole and may be located at a lower height than the second finger insertion hole.

[0009] Also, the second finger insertion hole may have the shape of an oblong hole that has a length in a direction orthogonal to a longitudinal direction of the second blade portion.

[0010] Also, the front end of the second holding tool may be coupled to the rear end of the second blade portion to be angle-adjustable in a left-right direction by an angle adjuster, and the angle adjuster may include a pair of first couplers formed to protrude from the rear end of the second blade portion and positioned to be spaced apart from each other in an up-down direction, a vertical rotating shaft vertically coupled between the first couplers to form a vertical center of rotation, a fastening hole formed to vertically pass through the first coupler located at a lower portion and eccentrically located at a front based on the vertical center of rotation of the vertical rotating shaft, a second coupler which is formed to protrude from the front end of the second holding tool and be inserted while crossing between the first couplers and has a front end coupled to the vertical rotating shaft to be horizontally rotatable, a plurality of angle adjustment holes formed to vertically pass through the second coupler and radially arranged about the vertical center of rotation of the vertical rotating shaft, and a fastening member of which an insertion portion at one side is vertically screw-coupled to the fastening hole through one of the angle adjustment holes at a lower portion of the first couplers and of which an adjustment portion at the other side is located to be caught on the lower portion or upper portion of the first couplers.

[0018] Also, FIG. 9 is a plan view showing the state in which the angle adjuster is applied to the scissors to be comfortably used by hand according to the present invention, FIG. 10 is a perspective view showing a state in which a pivoting portion is applied to the scissors to be comfortably used by hand according to the present invention, FIG. 11 is an exploded perspective view showing the state in which the pivoting portion is applied to the scissors to be comfortably used by hand according to the present invention, and FIG. 12 is a side view showing the state in which the pivoting portion is applied to the scissors to be comfortably used by hand according to the present invention.

[0019] Referring to FIGS. 1 to 12, scissors to be comfortably used by hand according to the present invention includes a first rotating body 100 in which a first handle portion 120 is formed at a rear end of a first blade portion 110 having a length in a front-rear direction and a second rotating body 200 which is connected to the first rotating body 100 to be able to rotate while crossing the first rotating body 100 about a hinge shaft and in which a second handle portion 220 is formed at a rear end of a second blade portion 210 having a length in the front-rear direction.

[0020] In particular, the first handle portion 120 includes a first holding tool 121 having a front end coupled to the rear end of the first blade portion 110 and a first finger insertion hole 122 formed to pass through both sides of the first holding tool 121 to be orthogonal to a longitudinal direction of the first blade portion 110 and formed to allow one or more fingers excluding a thumb to be inserted.

[0021] Also, the second handle portion 220 includes a second holding tool 221 located at an upper portion of the first holding tool 121 and having a front end coupled to the rear end of the second blade portion 210 and a second finger insertion hole 222 formed to pass through the second holding tool 221 in the front-rear direction to be orthogonal to the first finger insertion hole 122 and formed to allow the thumb to be inserted.

[0022] The first blade portion 110 and the first handle portion 120 have a structure in which vertical rotation is possible about a hinge shaft forming a horizontal center of rotation in a left-right direction, and the second blade portion 210 and the second handle portion 220 have a structure in which vertical rotation is possible about a hinge shaft forming a horizontal center of rotation in the left-right direction. Here, the first blade portion 110 has a structure in which vertical rotation is possible about the hinge shaft while one side of the first blade portion 110 in a width direction is in close contact with the second blade portion 210.

[0023] Also, a first cutting blade whose left-right width gradually decreases downward may be formed at a lower end of the first blade portion 110, and a second cutting blade whose left-right width gradually decreases upward may be formed at an upper end of the second blade portion 210. The first cutting blade and the second cutting blade may each have a length in the front-rear direction and may be formed in a front region based on the hinge shaft.

[0024] As illustrated in FIG. 5, when the first handle portion 120 and the second handle portion 220 are spaced apart in an up-down direction, a gap between the first handle portion 120 and the second handle portion 220 widens as the first handle portion 120 and the second handle portion 220 rotate about the hinge shaft. Simultaneously, as front regions of the first blade portion 110 and the second blade portion 210 rotate about the hinge shaft, the front regions are spaced apart in the up-down direction, and a gap is formed therebetween. An object to be cut may be placed through the gap between the first blade portion 110 and the second blade portion 210.

[0025] The first holding tool 121 may have a length in the front-rear direction, and the first finger insertion hole 122 may have a length in the front-rear direction to allow one or more fingers (index finger, middle finger, ring finger, little finger) of a user, excluding the user's thumb, to be inserted. That is, the user may insert one or more of the index finger, middle finger, ring finger, and little finger through the left side or right side of the first finger insertion hole 122 and then hold an upper region of the first holding tool 121 by surrounding the upper region from below.

[0026] Also, an inner circumferential surface of the first holding tool 121 may form a curved surface that is convex toward the first finger insertion hole 122, and a first support protrusion 123 may protrude from an upper end of the first holding tool 121 to come in contact with a lower end of a second support protrusion 223, which will be described below, when a gap between the first holding tool 121 and the second holding tool 221 is narrowed.

[0027] The second holding tool 221 may be located to be able to be seated on an upper end in a front region of the second holding tool 221 to allow the user to horizontally insert the thumb through the rear of the second finger insertion hole 222, and the second finger insertion hole 222 may have the shape of an oblong hole that has a length in a direction orthogonal to the longitudinal direction of the second blade portion 210 to allow the thumb to be selectively placed in the left-right direction.

[0028] The second finger insertion hole 222 has a length in the left-right direction in consideration of an angle of the user's thumb, and when the angle of the user's thumb is warped sideward, since an inner circumferential surface of the second finger insertion hole 222 does not press one side of the thumb, pain in the thumb can be minimized.

[0029] Also, an inner circumferential surface of the second holding tool 221 may form a curved surface that is convex toward the second finger insertion hole 222, and the second support protrusion 223 may protrude from a lower end of the second holding tool 221 to come in contact with the upper end of the first support protrusion 123, which has been described above, when the gap between the first holding tool 121 and the second holding tool 221 is narrowed.

[0030] Also, the rear end of the second blade portion 210 may be coupled to a lower region of the second holding tool 221 based on the second finger insertion hole 222 and may be located at a lower height than the second finger insertion hole 222. That is, when the user inserts the thumb through the second finger insertion hole 222, the front end of the thumb may be located above the second blade portion 210, and contact between the thumb and the second blade portion 210 may be prevented during scissoring.

[0031] For example, when the user holds the first holding tool 121 with one or more fingers excluding the thumb, and simultaneously, inserts the thumb through the rear of the second finger insertion hole 222, the longitudinal direction of the thumb and the direction in which the second finger insertion hole 222 is formed may remain parallel to each other, a force transmitted to the thumb during scissoring may vertically act on an upper end and a lower end of the second finger insertion hole 222, and since the thumb is not twisted in a diagonal direction, scissoring may be performed while the wrist is straight.

[0032] That is, since the thumb and wrist are maintained at a comfortable angle, pain in the thumb and wrist can be minimized even when the scissors are used for a long time. Also, since the second finger insertion hole 222 surrounds the circumference of the thumb in a direction orthogonal thereto, a length at which the thumb is inserted may increase, and since the second finger insertion hole 222 surrounds the circumference of the thumb, the thumb can be prevented from being separated during scissoring.

[0033] In the scissors to be comfortably used by hand according to one embodiment of the present invention, as in FIGS. 6 to 9, the front end of the second holding tool may be coupled to the rear end of the second blade portion to be angle-adjustable in the left-right direction by an angle adjuster 300.

[0034] The angle adjuster 300 may include a pair of first couplers 310 formed to protrude from the rear end of the second blade portion 210 and positioned to be spaced apart from each other in the up-down direction, a vertical rotating shaft 320 vertically coupled between the first couplers 310 to form a vertical center of rotation, a fastening hole 330 formed to vertically pass through one of the first couplers 310 and eccentrically located at a front based on the vertical center of rotation of the vertical rotating shaft 320, a second coupler 340 which is formed to protrude from the front end of the second holding tool 221 and be inserted while crossing between the first couplers 310 and has a front end coupled to the vertical rotating shaft 320 to be horizontally rotatable, a plurality of angle adjustment holes 350 formed to vertically pass through the second coupler 340 and radially arranged about the vertical center of rotation of the vertical rotating shaft 320, and a fastening member 360 of which an insertion portion at one side is vertically screw-coupled to the fastening hole 330 through one of the angle adjustment holes 350 at a lower portion or upper portion of the first couplers 310 and of which an adjustment portion at the other side is located to be caught on the lower portion or upper portion of the first couplers 310.

[0035] The pair of first couplers 310 may horizontally protrude to the rear of the second blade portion 210 and may be positioned to be spaced apart from each other at an upper portion of the first handle portion 120. Here, first curved surfaces 311 may be formed at protruding ends of the first couplers 310 to protrude forward while forming a semicircular curved surface along both sides, and since the first curved surfaces 311 form a curvature along a pivoting radius of the second coupler 340, the first curved surfaces 311 prevent the second coupler 340 from coming in contact with the front end of the second holding tool 221 when horizontally pivoting.

[0036] The vertical rotating shaft 320 may have an upper end and a lower end coupled to the first couplers 310 located in the up-down direction, and an angle of the second holding tool 221 may be changed as the second coupler 340 horizontally rotates about the vertical center of rotation formed by the vertical rotating shaft 320.

[0037] The fastening hole 330 may have threads continuously formed along an inner circumferential surface thereof to allow the insertion portion of the fastening member 360 to be vertically coupled by screw coupling, and corresponding threads may be formed on an outer circumferential surface of the insertion portion to be screw-coupled to the threads of the fastening hole 330.

[0038] The second coupler 340 may horizontally protrude from the front end of the second holding tool 221 and may be inserted while crossing between the first couplers 310. Here, a second curved surface 341 may be formed at a protruding end of the second coupler 340 to protrude forward while forming a semicircular curved surface along both sides to oppose the first curved surfaces 311. Since the second curved surface 341 forms a curvature along the pivoting radius of the second coupler 340, the second curved surface 341 may prevent the second coupler 340 from coming in contact with the rear end of the second blade portion 210 when horizontally pivoting.

[0039] The angle adjustment holes 350 are portions into which the insertion portion of the fastening member 360 is vertically inserted and may be radially arranged in a front region of the second coupler 340 based on the vertical rotating shaft 320. The number of angle adjustment holes 350, intervals therebetween, and the like may vary. The angle adjustment holes 350 may be positioned to be collinear with an upper portion of the fastening hole 330 when pivoting the second coupler 340. One of the angle adjustment holes 350 may be placed at an upper portion of the fastening hole 330, and then the insertion portion of the fastening member 360 may be coupled to the fastening hole 330 and the angle adjustment hole 350 by screw coupling.

[0040] For example, when the adjustment portion of the fastening member 360 is rotated in a decoupling direction, as the insertion portion of the fastening member 360 moves downward, the insertion portion is separated from the angle adjustment hole 350 and remains coupled to the fastening hole 330. In this state, the second coupler 340 may be freely pivoted, and the user may adjust the angle of the second holding tool 221 to correspond to the angle of insertion of the user's thumb.

[0041] On the other hand, when one of the angle adjustment holes 350 is placed to be collinear with the upper portion of the fastening hole 330, and then the adjustment portion of the fastening member 360 is rotated in a coupling direction, an upper end of the insertion portion may be vertically coupled through the angle adjustment hole 350 to fix the second coupler 340 at an adjusted angle. In this state, since the adjustment portion of the fastening member 360 may be located to be caught while exposed at a lower portion of the first couplers 310, and pivoting of the second coupler 340 is prevented, the second holding tool 221 may be maintained at an adjusted angle.

[0042] As in FIGS. 10 to 12, the scissors to be comfortably used by hand according to one embodiment of the present invention may further include a pivoting portion 400 formed to pivotably connect a rear end of the second coupler 340 and the front end of the second holding tool 221. The pivoting portion 400 may include a pair of third couplers 410 formed to protrude from the front end of the second holding tool 221 and positioned to be spaced apart from each other in the left-right direction, a horizontal rotating shaft 420 coupled between the third couplers 410 to form a horizontal center of rotation in the left-right direction, and a fourth coupler 430 which is formed to protrude from the rear end of the second coupler 340 and be inserted while crossing between the third couplers 410 and has a front end coupled to the horizontal rotating shaft 420 to be vertically rotatable.

[0043] The pair of third couplers 410 may be coupled to the lower region of the second holding tool 221 based on the second finger insertion hole 222 and may be located at a lower height than the second finger insertion hole 222. That is, when the user inserts the thumb through the second finger insertion hole 222, the front end of the thumb may be located above the third couplers 410, and contact between the thumb and the third couplers 410 may be prevented during scissoring.

[0044] For example, when the user moves the thumb upward or downward while scissoring, the upper end and lower end of the second finger insertion hole 222 sequentially come in contact with the upper end and lower end of the thumb, and the angle of the thumb slightly changes according to the height at which the thumb is lifted. That is, since a vertical angle of the second holding tool 221 can be changed to correspond to the angle of the thumb that changes when the thumb is lifted, and the second finger insertion hole 222 and the thumb can be changed at the same angle, friction force (rubbing) that acts on the thumb can be reduced.

[0045] Consequently, according to the present invention, since the thumb is inserted while the longitudinal direction thereof is collinear with the direction in which the second finger insertion hole 222 is formed, the thumb and wrist are not twisted when scissoring, and scissors can be held in a comfortable posture, and since the thumb and wrist are maintained at a comfortable angle, pain in the thumb and wrist can be minimized even when the scissors are used for a long time. Also, since the second finger insertion hole 222 surrounds the circumference of the thumb in a direction orthogonal thereto, the thumb is not easily separated during scissoring.

[0046] Also, according to the present invention, since the user can mount his or her thumb at a desired angle, various user needs can be met, and since the second finger insertion hole 222 and the thumb can be changed at the same angle during scissoring, friction force acting on the thumb while changing the angle is not high.

[0047] According to the present invention, since a thumb is inserted while a longitudinal direction thereof is collinear with a direction in which a second finger insertion hole is formed, the thumb and wrist are not twisted when scissoring, and scissors can be held in a comfortable posture, and since the thumb and wrist are maintained at a comfortable angle, pain in the thumb and wrist can be minimized even when the scissors are used for a long time. Also, since the second finger insertion hole surrounds the circumference of the thumb in a direction orthogonal thereto, the thumb is not easily separated during scissoring.

[0048] Also, according to the present invention, since a user can mount his or her thumb at a desired angle, various user needs can be met, and since the second finger insertion hole and the thumb can be changed at the same angle during scissoring, friction force acting on the thumb while changing the angle is not high.

[0049] Specific embodiments of the scissors to be comfortably used by hand according to the present invention have been described above, but it is apparent that various modifications may be made within the scope not departing from the scope of the present invention.

[0050] Therefore, the scope of the present invention should not be defined as being limited to the embodiments described herein and should be defined by the claims below and their equivalents.

[0051] That is, the embodiments described above should be understood as being illustrative, instead of limiting, in all aspects, the scope of the present invention is shown by the claims below rather than by the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and concepts equivalent thereto should be interpreted as belonging to the scope of the present invention.
