Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when a user holds hair-cutting scissors, it is easier to hold the hair-cutting scissors if the thickness of the handle part on the stationary blade side where the four fingers (index finger, middle finger, ring finger, and little finger) of the user's hand are caught is thicker. However, if the thickness of the handle part on the stationary blade side is increased, there is a problem that the weight of the hair-cutting scissors increases.

[0005] The present invention has been made in view of such points, and an object thereof is to provide a hair-cutting scissor that is easier to hold than conventional ones while suppressing an increase in weight.

Means for Solving the Problems

[0006] To achieve the above objective, the present invention provides a pair of barber scissors comprising a stationary blade and a moving blade, wherein the stationary blade has a first blade member and a first handle member connected to the first blade member, the first handle member is made of a metal material and comprises a first plate-shaped member connected to the first blade member and a first thickness-adding member made of a resin material or wood and having a thickness greater than the first plate-shaped member, the first thickness-adding member is fixed to the first plate-shaped member by being superimposed on it such that its first surface is in surface contact with a second surface of the first plate-shaped member that is opposite to the first surface.

[0007] With the present invention configured in this way, the first thickness-adding member is made of resin or wood, so the increase in weight of the stationary blade can be suppressed compared to the case where the first thickness-adding member is made of metal. Furthermore, since the first thickness-adding member is fixed to the first plate-shaped member by being superimposed on it so that its first surface is in surface contact with the second surface of the first plate-shaped member that is opposite to the first surface, the thickness of the first handle member becomes thicker than in the conventional invention. This makes it easier for the user to grip the first handle member. Therefore, it is possible to provide barber scissors that are easier to grip than conventional scissors while suppressing an increase in weight.

[0008] In the present invention, preferably, the moving blade body has a second blade member and a second handle member connected to the second blade member, the second handle member being made of a metal material and comprising a second plate-shaped member connected to the second blade member and a second thickness-adding member being made of a resin material or wood and having a thickness greater than that of the second plate-shaped member, the second thickness-adding member being fixed on top of the second plate-shaped member such that its third surface is in surface contact with a fourth surface of the second plate-shaped member that is opposite to the third surface.

[0009] With the present invention configured in this way, the second thickness-adding member is fixed to the second plate-shaped member by being superimposed on it such that its third surface is in surface contact with the fourth surface of the second plate-shaped member that is opposite to the third surface. This makes it easier to match the thickness of the second handle member with the thickness of the first handle member. As a result, the barber scissors become even easier to grip.

[0010] In the present invention, preferably, the stationary blade and the moving blade are further provided with pivots that are sequentially fitted into pivot holes provided in the first blade member and the second blade member, respectively, and that rotatably connect the stationary blade and the moving blade so that the first blade member and the second blade member open and close by the approaching and separating movements of the first handle member and the second handle member, the first plate-shaped member is provided with a first ring portion into which the user's ring finger can be inserted, the first thickness-adding member is provided with a second ring portion into which the user's ring finger can be inserted, and the second plate-shaped member is provided with a portion into which the user's thumb can be inserted A third ring portion is provided, and the second thickness-adding member is provided with a fourth ring portion into which the user's thumb can be inserted. The first thickness-adding member and the second thickness-adding member are made of wood. The first plate-shaped member of the first handle member is located on one end of the pivot, while the first thickness-adding member of the first handle member is located on the other end of the pivot. The second plate-shaped member of the second handle member is located on the other end of the pivot, while the second thickness-adding member of the second handle member is located on one end of the pivot.

[0011] With the present invention configured in this way, the first plate-shaped member of the first handle member is located on one end of the pivot, while the first thickness-adding member of the first handle member is located on the other end of the pivot. This makes it easier for the user's index finger, middle finger, etc., to come into contact with the first thickness-adding member when gripping the first handle member. Furthermore, the second plate-shaped member of the second handle member is located on the other end of the pivot, while the second thickness-adding member of the second handle member is located on one end of the pivot. This makes it easier for the user's thumb to come into contact with the second thickness-adding member when gripping the second handle member. In addition, since the first and second thickness-adding members are made of wood, which has a better feel to the touch than metal, the user can use the barber scissors while in contact with the relatively pleasant-feeling parts of the first and second handle members.

[0012] In the present invention, preferably, the second ring portion has a first notch portion cut out to connect the inner region of the second ring portion with the outer region in the width direction, and the portion of the first plate-like member corresponding to the first notch portion is provided with a first bent portion that is bent toward the first thickness-adding member in the thickness direction of the first plate-like member.

[0013] With the present invention configured in this way, the portion of the first plate-shaped member corresponding to the first notch is provided with a first bent portion that is bent toward the first thickness-adding member in the thickness direction of the first plate-shaped member. This makes it easier for the user to insert their ring finger into the first ring portion from the first plate-shaped member side when gripping the first handle member.

[0014] In the present invention, preferably, the fourth ring portion has a second notch portion cut out to connect the inner region of the fourth ring portion with the outer region in the width direction, and the portion of the second plate-like member corresponding to the second notch portion is provided with a second bent portion that is bent in the thickness direction of the second plate-like member on the side opposite to the second thickness-adding member.

[0015] With the present invention configured in this way, the portion of the second plate-shaped member corresponding to the second notch is provided with a second bent portion that is bent in the thickness direction of the second plate-shaped member on the opposite side from the second thickness-adding member. This makes it easier for the user to insert their thumb into the third ring portion from the second thickness-adding member side when gripping the second handle member.

[0016] In the present invention, preferably, the outer end in the width direction of the first plate-like member is located further outward in the width direction than the outer end in the width direction of the first thickness-adding member.

[0017] With the present invention configured in this way, since the outer end in the width direction of the first plate-shaped member is located further outward in the width direction than the outer end in the width direction of the first thickness-adding member, the user can easily position their index finger or middle finger relative to the first plate-shaped member by bringing their index finger or middle finger into contact with the outer end in the width direction of the first plate-shaped member when gripping the first handle member. Furthermore, since the outer end in the width direction of the first thickness-adding member is located further inward in the width direction than the outer end in the width direction of the first plate-shaped member, in other words, the first thickness-adding member is recessed inward in the width direction, it becomes easier for the user to hook their index finger or middle finger onto the first handle member.

[0018] In the present invention, preferably, the first thickness-adding member further comprises a first curved portion that can come into contact with the user's index finger and a second curved portion that can come into contact with the user's middle finger.

[0019] With the present invention configured in this way, when the user grips the first handle member, the user's index finger comes into contact with the first curved surface and the middle finger comes into contact with the second curved surface, thereby reducing the burden on the user when gripping the first handle member.

[0020] In the present invention, preferably, the fourth ring portion further comprises a third curved portion that can come into contact with the user's thumb.

[0021] With the present invention configured in this way, when the user grips the second handle member, the user's thumb comes into contact with the third curved surface, thus reducing the burden on the user when gripping the second handle member.

[0022] In the present invention, preferably, the present invention further comprises a first weight-adjusting member and a second weight-adjusting member made of a metal material, wherein the first weight-adjusting member is disposed in a first gap provided between the first plate-shaped member and the first thickness-adding member, and the second weight-adjusting member is disposed in a second gap provided between the second plate-shaped member and the second thickness-adding member.

[0023] According to the present invention configured as described above, for example, when the weight of the tip side portion of the hair cutting scissors is relatively heavy, the first weight adjusting member is disposed in the first gap portion of the first handle member, and the second weight adjusting member is disposed in the second gap portion of the second handle member, whereby it becomes possible to improve the weight balance between the tip side portion and the base end side portion of the hair cutting scissors.

[0024] In the present invention, preferably, the inner diameter of the second finger ring portion is set to a dimension smaller than the inner diameter of the first finger ring portion, and the inner diameter of the fourth finger ring portion is set to a dimension smaller than the inner diameter of the third finger ring portion.

[0025] According to the present invention configured as described above, since the inner diameter of the second finger ring portion is set to a dimension smaller than the inner diameter of the first finger ring portion, and the inner diameter of the fourth finger ring portion is set to a dimension smaller than the inner diameter of the third finger ring portion, for example, in the case of a user with relatively thick fingers, by using a file or the like to cut the second finger ring portion and the fourth finger ring portion, it becomes possible to easily adjust their sizes. Thereby, it becomes possible to provide hair cutting scissors that are easy to grip for a user with relatively thick fingers. Further, since the first thickness adding member provided with the second finger ring portion and the second thickness adding member provided with the fourth finger ring portion are made of wood, they can be easily cut compared to metal materials.

[0026] In the present invention, preferably, the first finger ring portion has a third notch portion that is cut out so as to communicate the inner region and the outer region in the width direction of the first finger ring portion, and the second finger ring portion has a fourth curved surface portion that can contact the ring finger of the user.

[0027] According to the present invention configured as described above, since the first finger ring portion has a third notch portion that is cut out so as to communicate the inner region and the outer region in the width direction of the first finger ring portion, and the second finger ring portion has a fourth curved surface portion that can contact the ring finger of the user, it becomes possible to increase the degree of freedom of the ring finger of the user that is inserted into the first finger ring portion and the second finger ring portion when the user grips the first handle member. Thereby, it becomes possible to improve the operability of the hair cutting scissors during a hair cutting operation.

[0028] In the present invention, preferably, the first plate-shaped member has a first fitting hole formed through the thickness direction of the first plate-shaped member, and the first surface of the first thickness-adding member is provided with a first fitting projection that can be fitted into the first fitting hole, and the second plate-shaped member has a second fitting hole formed through the thickness direction of the second plate-shaped member, and the third surface of the second thickness-adding member is provided with a second fitting projection that can be fitted into the second fitting hole.

[0029] With the present invention configured in this way, the first fitting hole of the first plate-shaped member and the first fitting projection of the first thickness-adding member fit together, and the second fitting hole of the second plate-shaped member and the second fitting projection of the second thickness-adding member fit together, thereby enabling the positioning of the first plate-shaped member and the first thickness-adding member, and the positioning of the second plate-shaped member and the second thickness-adding member. [Effects of the Invention]

[0030] This allows us to provide barber scissors that are easier to grip than conventional models while keeping the weight increase to a minimum. [Brief explanation of the drawing]

[0032] Embodiments of the present invention will be described in detail below with reference to the drawings. The following description of preferred embodiments is essentially illustrative.

[0033] Embodiment 1 of the Invention <Overview of Hairdressing Scissors 1> Figures 1 to 6 show a barber's scissors 1 according to Embodiment 1 of the present invention. The barber's scissors 1 are used by barbers and other users during barbering work and are equipped with a pair of stationary blades 10 and a moving blade 20 (see Figures 1 to 4).

[0034] As shown in Figures 3 and 4, the stationary blade body 10 comprises a first blade member 11 having a first blade portion 11a and a first intermediate portion 11b, and a first handle member 12 connected to the first blade member 11. Furthermore, in the state in which the first blade member 11 and the first handle member 12 are connected, the first blade portion 11a of the first blade member 11, the first intermediate portion 11b of the first blade member 11, and the first handle member 12 are arranged in order from the tip side.

[0035] As shown in Figures 1 and 2, the moving blade body 20 comprises a second blade member 21 having a second blade portion 21a and a second intermediate portion 21b, and a second handle member 22 connected to the second blade member 21. Furthermore, in the state in which the second blade member 21 and the second handle member 22 are connected, the second blade portion 21a of the second blade member 21, the second intermediate portion 21b of the second blade member 21, and the second handle member 22 are arranged in order from the tip side.

[0036] The stationary blade body 10 and the moving blade body 20 are overlapped at the first intermediate section 11b and the second intermediate section 21b so as to intersect (see Figures 1 to 4). The first intermediate section 11b and the second intermediate section 21b are each provided with shaft support holes 3 (see Figures 5(a) and 5(b)) that penetrate in the direction of overlap of the stationary blade body 10 and the moving blade body 20. A pivot 4 is sequentially fitted into the shaft support holes 3 provided in the first intermediate section 11b of the first blade member 11 and the second intermediate section 21b of the second blade member 21. The pivot 4 connects the stationary blade body 10 and the moving blade body 20 so as to be rotatable relative to each other, so that the first blade member 11 and the second blade member 21 open and close as the first handle member 12 and the second handle member 22 move closer to and further apart from each other.

[0037] <Structure of the stationary blade body 10> As shown in Figures 3 and 4, the stationary blade body 10 comprises a first blade member 11 disposed on the tip side of the stationary blade body 10 and having a substantially triangular shape with a sharp tip when viewed from the front, and a first handle member 12 provided on the base end side of the first blade member 11.

[0038] The first blade member 11 is formed by cutting it out of stainless steel cutting material using wire electrical discharge machining.

[0039] As shown in Figure 5(a), a first mounting surface portion 14 is formed on the first handle member 12 side of the first blade member 11, with the surface side recessed in a stepped shape so that the thickness is approximately half.

[0040] The first handle member 12 comprises a first plate-shaped member 15 connected to the first blade member 11 and a first thickness-adding member 16. The first thickness-adding member 16 is fixed to the first plate-shaped member 15 by being superimposed on it, such that its first surface 16s is in surface contact with a second surface 15s of the first plate-shaped member 15 that is opposite to the first surface 16s. The first surface 16s and the second surface 15s are in surface contact with each other as flat surfaces.

[0041] The first plate-shaped member 15 is a flat plate and is made of a metal material (for example, stainless steel). The first plate-shaped member 15 is located on one end side of the pivot 4 than the first mounting surface portion 14. The first plate-shaped member 15 comprises, in order from the base end side of the stationary blade body 10, a first little finger rest portion 15a, a ring portion 15b on the ring finger base side into which the user's ring finger can be inserted, a first handle portion 15c on the outer edge where the user's index and middle fingers are placed for operation, and a first extension portion 15d extending from the first handle portion 15c toward the first intermediate portion 11b. The ring portion 15b on the ring finger base side has a curved shape that protrudes outward in the width direction from the first little finger rest portion 15a, the first handle portion 15c, and the first extension portion 15d (see Figure 3). In Embodiment 1, the "width direction" refers to the orthogonal direction perpendicular to the longitudinal direction of the barber scissors 1, in other words, the direction in which the first handle member 12 and the second handle member 22 of the barber scissors 1 are aligned when closed.

[0042] The first extension portion 15d and the first mounting surface portion 14 of the first blade member 11 are fixed together by the first screw B1. In Embodiment 1, the first mounting surface portion 14 of the first blade member 11 is fixed to the first extension portion 15d while resting on the portion of the first intermediate portion 11b side of the first extension portion 15d. In this fixed state, the first extension portion 15d is located on one end side of the pivot 4, the first mounting surface portion 14 is located on the other end side of the pivot 4, and the surface of the first intermediate portion 11b and the surface of the first extension portion 15d are flush.

[0043] The first thickness-adding member 16 is made of wood (for example, padauk or ebony) and is thicker than the first plate-like member 15. In Embodiment 1, the thickness of the first plate-like member 15 is set to approximately 1.5 mm, and the thickness of the first thickness-adding member 16 is set to approximately 5 mm.

[0044] Furthermore, as shown in Figures 3 and 4, the first thickness-adding member 16 has a shape that follows the contour of the first plate-shaped member 15 when viewed in the thickness direction, and comprises, in order from the base end side of the stationary blade body 10, a second little finger rest portion 16a, a ring finger tip side ring portion 16b into which the user's ring finger can be inserted, and a second handle portion 16c which is the part on the outer periphery edge that the user's index and middle fingers rest on for operation. The first thickness-adding member 16 is fixed so as to be in surface contact with the first plate-shaped member 15 when its second little finger rest portion 16a is aligned with the first little finger rest portion 15a of the first plate-shaped member 15, its ring finger tip side ring portion 16b is aligned with the ring finger base side ring portion 15b of the first plate-shaped member 15, and its second handle portion 16c is aligned with the first handle portion 15c of the first plate-shaped member 15. In this fixed state, the first plate-shaped member 15 of the first handle member 12 is located on one end side of the pivot 4, while the first thickness-adding member 16 of the first handle member 12 is located on the other end side of the pivot 4 (see Figure 5(a)). Furthermore, when the first thickness-adding member 16 is fixed to the first plate-shaped member 15, the outer end in the width direction of the first plate-shaped member 15 is located further out in the width direction than the outer end in the width direction of the first thickness-adding member 16. In Embodiment 1, the first thickness-adding member 16 and the first plate-shaped member 15 are bonded together. Also, in Embodiment 1, the first thickness-adding member 16 does not have an extension portion that extends from the second handle portion 16c toward the first intermediate portion 11b. As a result, the first plate-shaped member 15 has a first extension portion 15d that extends toward the first intermediate portion 11b side than the first thickness-adding member 16 and is connected to the first intermediate portion 11b, while the first thickness-adding member 16 is spaced apart from the first intermediate portion 11b.

[0045] The ring finger tip side ring portion 16b of the first thickness-adding member 16 has a first notch portion 16d that is cut out to connect the inner region and the widthwise outer region of the ring finger tip side ring portion 16b (see Figure 3). The portion of the first plate-shaped member 15 corresponding to the first notch portion 16d is provided with a first bent portion 15e that is bent toward the first thickness-adding member 16 in the thickness direction of the first plate-shaped member 15 (thickness direction of the first handle member 12) (see Figure 5(a)).

[0046] Furthermore, the second handle portion 16c of the first thickness-adding member 16 is provided with a first chamfered portion 16e that can contact the user's index finger, a second chamfered portion 16f that can contact the user's middle finger, and a third chamfered portion 16g that can contact the user's ring finger. In Embodiment 1, the first chamfered portion 16e and the second chamfered portion 16f are formed by chamfering the outer corner portion in the width direction of the second handle portion 16c. The third chamfered portion 16g is formed by chamfering the outer corner portion in the width direction of the ring finger tip portion 16b.

[0047] <Configuration of the moving blade body 20> As shown in Figures 1 and 2, the moving blade body 20 comprises a second blade member 21 disposed on the tip side of the moving blade body 20 and having a substantially triangular shape with a sharp tip when viewed from the front, and a second handle member 22 provided on the base end side of the second blade member 21.

[0048] The second blade member 21 is formed by cutting it out of stainless steel cutting material using wire electrical discharge machining.

[0049] As shown in Figure 5(b), a second mounting surface portion 24 is formed on the second handle member 22 side of the second blade member 21, with the surface side recessed in a stepped shape so that the thickness is approximately half.

[0050] The second handle member 22 comprises a second plate-shaped member 25 connected to the second blade member 21 and a second thickness-adding member 26. The second thickness-adding member 26 is fixed to the second plate-shaped member 25 by being superimposed on it, such that its third surface 26s is in surface contact with the fourth surface 25s of the second plate-shaped member 25 that is opposite to the third surface 26s. The third surface 26s and the fourth surface 25s are in surface contact with each other as flat surfaces.

[0051] The second plate-shaped member 25 is a flat plate and is made of a metal material (for example, stainless steel). The second plate-shaped member 25 is located on the other end side of the pivot 4, relative to the second mounting surface 24. The second plate-shaped member 25 comprises, in order from the base end side of the moving blade body 20, a thumb-tip ring portion 25a into which the user's thumb can be inserted, a third handle portion 25b, and a second extension portion 25c extending from the third handle portion 25b toward the second intermediate portion 21b. The thumb-tip ring portion 25a has a curved shape that protrudes outward in the width direction from the third handle portion 25b and the second extension portion 25c (see Figure 1).

[0052] The second extension portion 25c and the second mounting surface portion 24 of the second blade member 21 are fixed together by the second screw B2. In Embodiment 1, the second mounting surface portion 24 of the second blade member 21 is fixed to the second extension portion 25c in a state where it is placed on the portion of the second intermediate portion 21b side of the second extension portion 25c. In this fixed state, the second extension portion 25c is located on the other end side of the pivot 4, the second mounting surface portion 24 is located on the one end side of the pivot 4, and the surface of the second intermediate portion 21b and the surface of the second extension portion 25c are flush.

[0053] The second thickness-adding member 26 is made of wood (for example, padauk or ebony) and is thicker than the second plate-shaped member 25. In Embodiment 1, the thickness of the second plate-shaped member 25 is set to approximately 1.5 mm, and the thickness of the second thickness-adding member 26 is set to approximately 5 mm.

[0054] Furthermore, as shown in Figures 1 and 2, the second thickness-adding member 26 has a shape that follows the contour of the second plate-shaped member 25 when viewed in the thickness direction, and includes, in order from the base end side of the moving blade body 20, a thumb base ring portion 26a into which the user's thumb can be inserted, and a fourth handle portion 26b. The thumb base ring portion 26a protrudes toward the stationary blade body 10 side and includes a block-shaped hit point portion 26c that contacts the first thickness-adding member 16 (second handle member 22) when the first blade portion 11 and the second blade portion 21 are closed, preventing further rotation of the stationary blade body 10 and the moving blade body 20. Furthermore, the second thickness-adding member 26 is fixed so as to be in surface contact with the second plate-shaped member 25 when its thumb base ring portion 26a is aligned with the thumb tip ring portion 25a of the second plate-shaped member 25, and its fourth handle portion 26b is aligned with the third handle portion 25b of the second plate-shaped member 25. In this fixed state, the second plate-shaped member 25 on the second handle member 22 is located on the other end side of the pivot 4, while the second thickness-adding member 26 on the second handle member 22 is located on the one end side of the pivot 4 (see Figure 5(b)). Also, when the second thickness-adding member 26 is fixed to the second plate-shaped member 25, the widthwise outer end of the second plate-shaped member 25 is located widthwise outward from the widthwise outer end of the second thickness-adding member 26. In Embodiment 1, the second thickness-adding member 26 and the second plate-shaped member 25 are bonded together. Furthermore, in Embodiment 1, the second thickness-adding member 26 does not have an extension portion extending from the fourth handle portion 26b toward the second intermediate portion 21b. As a result, the second plate-shaped member 25 has a second extension portion 25c that extends toward the second intermediate portion 21b than the second thickness-adding member 26 and is connected to the second intermediate portion 21b, while the second thickness-adding member 26 is spaced apart from the second intermediate portion 21b.

[0055] The thumb-base side ring portion 26a of the second thickness-adding member 26 has a second notch portion 26d that is cut out to connect the inner region and the widthwise outer region of the thumb-base side ring portion 26a (see Figure 1). The portion of the second plate-shaped member 25 corresponding to the second notch portion 26d is provided with a second bent portion 25d that is bent in the thickness direction of the second plate-shaped member 25 (thickness direction of the second handle member 22) on the opposite side from the second thickness-adding member 26 (see Figure 5(b)).

[0056] Furthermore, the thumb-base side ring portion 26a of the second thickness-adding member 26 is provided with a fourth chamfered portion 26e that can come into contact with the user's thumb. In Embodiment 1, the fourth chamfered portion 26e is formed by chamfering the outer corner portion in the width direction of the thumb-base side ring portion 26a, thereby creating a smooth curved surface.

[0057] As described above, according to Embodiment 1, since the first thickness-adding member 16 is made of wood, the weight increase of the stationary blade body 10 can be suppressed compared to the case where the first thickness-adding member 16 is made of metal. Furthermore, since the first thickness-adding member 16 is fixed to the first plate-shaped member 15 by overlapping it such that its first surface 16s is in surface contact with the second surface 15s of the first plate-shaped member 15 that is opposite to the first surface 16s, the thickness of the first handle member 12 becomes thicker than in the conventional design. This makes it easier for the user to grip the first handle member 12. Therefore, it is possible to provide a barber's scissors 1 that is easier to grip than conventional scissors while suppressing the increase in weight.

[0058] Furthermore, since the second thickness-adding member 26 is fixed to the second plate-shaped member 25 by overlapping it such that its third surface 26s is in surface contact with the fourth surface 25s of the second plate-shaped member 25 that is opposite to the third surface 26s, it becomes easier to match the thickness of the second handle member 22 with the thickness of the first handle member 12. As a result, the hairdressing scissors 1 becomes even easier to grip.

[0059] Furthermore, since the first plate-shaped member 15 of the first handle member 12 is located on one end of the pivot 4, while the first thickness-adding member 16 of the first handle member 12 is located on the other end of the pivot 4, when the user grips the first handle member 12, the user's index finger, middle finger, etc., are more likely to come into contact with the first thickness-adding member 16. Similarly, since the second plate-shaped member 25 of the second handle member 22 is located on the other end of the pivot 4, while the second thickness-adding member 26 of the second handle member 22 is located on one end of the pivot 4, when the user grips the second handle member 22, the user's thumb is more likely to come into contact with the second thickness-adding member 26. Moreover, since the first thickness-adding member 16 and the second thickness-adding member 26 are made of wood, which has a better feel to the touch than metal, the user can use the barber scissors 1 while in contact with the relatively pleasant-feeling parts of the first handle member 12 and the second handle member 22.

[0060] Furthermore, since the first thickness-adding member 16 is thicker than the first plate-like member 15, the first chamfered portion 16e and the second chamfered portion 16f can be formed more broadly. This makes it easier to form the first chamfered portion 16e and the second chamfered portion 16f into a curved shape that conforms to the fingertip of the index or middle finger.

[0061] Furthermore, since the second thickness-adding member 26 is thicker than the second plate-shaped member 25, the fourth chamfered portion 26e can be formed more broadly. This makes it easier to form the fourth chamfered portion 26e into a curved shape that conforms to the pad of the thumb.

[0062] Furthermore, the portion of the first plate-shaped member 15 corresponding to the first notch 16d is provided with a first bent portion 15e that is bent toward the first thickness-adding member 16 in the thickness direction of the first plate-shaped member 15, making it easier for the user to insert their ring finger from the first plate-shaped member 15 side into the ring finger base portion 15b when gripping the first handle member 12.

[0063] Furthermore, the portion of the second plate-shaped member 25 corresponding to the second notch 26d is provided with a second bent portion 25d that is bent in the thickness direction of the second plate-shaped member 25 on the opposite side from the second thickness-adding member 26. This makes it easier for the user to insert their thumb into the thumb-tip ring portion 25a from the second thickness-adding member 26 side when gripping the second handle member 22.

[0064] Furthermore, as shown in Figure 6 (for convenience, the index finger is not shown in Figure 6), since the outer edge in the width direction of the first plate-like member 15 is located further outward in the width direction than the outer edge in the width direction of the first thickness-adding member 16, the user can easily position their index and middle fingers relative to the first plate-like member 15 by bringing them into contact with the outer edge in the width direction of the first plate-like member 15 when gripping the first handle member 12. Also, since the outer edge in the width direction of the first thickness-adding member 16 is located further inward in the width direction than the outer edge in the width direction of the first plate-like member 15, in other words, the first thickness-adding member 16 is recessed inward in the width direction, it becomes easier for the user to hook their index and middle fingers onto the first handle member 12.

[0065] Furthermore, when the user grips the first handle member 12, the user's index finger comes into contact with the first chamfered portion 16e and the middle finger comes into contact with the second chamfered portion 16f, thus reducing the burden on the user when gripping the first handle member 12.

[0066] Furthermore, when the user grips the second handle member 22, the user's thumb comes into contact with the fourth chamfered portion 26e, thus reducing the burden on the user when gripping the second handle member 22.

[0067] As shown in Figures 7(a) and 7(b), the barber scissors 1 may further include a first weight adjustment member 50 and a second weight adjustment member 60 made of a metal material (for example, stainless steel), wherein the first weight adjustment member 50 is disposed in a first gap 51 provided between the first plate-shaped member 15 and the first thickness-adding member 16, and the second weight adjustment member 60 is disposed in a second gap 61 provided between the second plate-shaped member 25 and the second thickness-adding member 26. In this way, for example, if the weight of the tip portion of the barber scissors 1 (first blade member 11 and second blade member 21) is relatively heavy, the first weight adjustment member 50 is placed in the first gap 51 of the first handle member 12, and the second weight adjustment member 60 is placed in the second gap 61 of the second handle member 22, thereby improving the weight balance between the tip portion (first blade member 11 and second blade member 21) and the base portion (first handle member 12 and second handle member 22) of the barber scissors 1.

[0068] Furthermore, in Embodiment 1, the description used an example in which the moving blade body 20 comprises a second blade member 21 having a first blade portion 11a and a first intermediate portion 11b, and a second handle member 22 having a second plate-shaped member 25 and a second thickness-adding member 26 connected to the second blade member 21. However, the configuration in which the second blade member 21 and the second handle member 22 are connected, the configuration in which the second blade member 21 has a first blade portion 11a and a first intermediate portion 11b, and the configuration in which the second handle member 22 has a second plate-shaped member 25 and a second thickness-adding member 26 are not essential. For example, a moving blade body (not shown) in which the blade portion, intermediate portion, and handle portion are integrally formed may also be used.

[0069] Furthermore, although Embodiment 1 described an example in which the first thickness-adding member 16 and the second thickness-adding member 26 are made of wood, both the first thickness-adding member 16 and the second thickness-adding member 26, or either the first thickness-adding member 16 or the second thickness-adding member 26, may be made of a resin material (for example, polypropylene).

[0070] Furthermore, in Embodiment 1, an example was described in which the thickness of the first plate-like member 15 and the second plate-like member 25 was set to approximately 1.5 mm, and the thickness of the first thickness-adding member 16 and the second thickness-adding member 26 was set to approximately 5 mm. However, as long as the thickness of the first thickness-adding member 16 and the second thickness-adding member 26 is set to be thicker than the thickness of the first plate-like member 15 and the second plate-like member 25, these thicknesses may be changed as appropriate.

[0071] Furthermore, in Embodiment 1, an example was described in which the first plate-like member 15 and the first thickness-adding member 16 are bonded together, and the second plate-like member 25 and the second thickness-adding member 26 are bonded together. However, the members may be fixed together using means other than bonding (for example, screws, rivets, etc.).

[0072] Furthermore, although Embodiment 1 described an example in which the first handle member 12 includes a first bent portion 15e and a first notched portion 16d, these may not be included.

[0073] Furthermore, although Embodiment 1 described an example in which the second handle member 22 includes a second bent portion 25d and a second notched portion 26d, these may not be included.

[0074] Furthermore, while Embodiment 1 describes an example in which the outer end of the first plate-like member 15 in the width direction is located further outward in the width direction than the outer end of the first thickness-adding member 16 in the width direction, the outer ends of the first plate-like member 15 in the width direction and the outer ends of the first thickness-adding member 16 in the width direction may be aligned, or the outer end of the first plate-like member 15 in the width direction may be located further inward in the width direction than the outer end of the first thickness-adding member 16 in the width direction.

[0075] Furthermore, in Embodiment 1, the first handle member 12 was described using an example that includes a first chamfered portion 16e, a second chamfered portion 16f, and a third chamfered portion 16g that can come into contact with the user's ring finger, but these may not be included.

[0076] Furthermore, although Embodiment 1 described an example in which the second handle member 22 is provided with a fourth chamfered portion 26e, it is not necessary to provide this chamfered portion.

[0077] Embodiment 2 of the Invention Next, a barber scissors 1 according to Embodiment 2 of the present invention will be described using Figures 8 and 9. In Embodiment 2, the explanation will focus on the differences from Embodiment 1.

[0078] As shown in Figures 1 and 3, in the first embodiment, the inner diameter of the ring finger tip portion 16b was set to be larger than the inner diameter of the ring finger base portion 15b, and the inner diameter of the thumb base portion 26a was set to be larger than the inner diameter of the thumb tip portion 25a. However, as shown in Figures 8 and 9, in the second embodiment, the inner diameter of the ring finger tip portion 16b was set to be smaller than the inner diameter of the ring finger base portion 15b, and the inner diameter of the thumb base portion 26a was set to be smaller than the inner diameter of the thumb tip portion 25a.

[0079] Furthermore, as shown in Figures 1 and 3, in Embodiment 1, the ring finger tip side ring portion 16b of the first thickness-adding member 16 has a first notch portion 16d cut out to connect the inner region and the widthwise outer region of the ring finger tip side ring portion 16b, and the thumb base side ring portion 26a of the second thickness-adding member 26 has a second notch portion 26d cut out to connect the inner region and the widthwise outer region of the thumb base side ring portion 26a. However, as shown in Figures 8 and 9, in Embodiment 2, the ring finger tip side ring portion 16b does not have the first notch portion 16d, and the thumb base side ring portion 26a does not have the second notch portion 26d. As shown in Figure 8, in Embodiment 2, the ring finger base side ring portion 15b of the first plate-shaped member 15 has a third notch portion 15f that is cut out to connect the inner region and the widthwise outer region of the ring finger base side ring portion 15b.

[0080] In Embodiment 2, the ring finger tip portion 16b of the first thickness-adding member 16 has a fifth chamfered portion 16h that can come into contact with the user's ring finger (see Figure 8). The fifth chamfered portion 16h is formed by chamfering the corner portion of the inner peripheral edge on the first surface 16s side of the ring finger tip portion 16b, thereby creating a smooth curved surface.

[0081] In Embodiment 2, the first plate-like member 15 has a first fitting hole 15g formed through the first plate-like member 15 in the thickness direction. The first fitting hole 15g has a substantially elongated shape when viewed in the thickness direction of the first plate-like member 15. The first surface 16s of the first thickness-adding member 16 is provided with a first fitting projection 16i that can be fitted into the first fitting hole 15g. For example, the first fitting projection 16i is bonded to the first surface 16s of the first thickness-adding member 16.

[0082] In Embodiment 2, the second plate-like member 25 has a second fitting hole 25e formed through the second plate-like member 25 in the thickness direction. The second fitting hole 25e is substantially triangular in shape when viewed in the thickness direction of the second plate-like member 25. The third surface 26s of the second thickness-adding member 26 is provided with a second fitting projection 26f that can be fitted into the second fitting hole 25e. For example, the second fitting projection 26f is bonded to the third surface 26s of the second thickness-adding member 26.

[0083] As described above, according to Embodiment 2, the inner diameter of the ring finger tip side ring portion 16b is set to be smaller than the inner diameter of the ring finger base side ring portion 15b, and the inner diameter of the thumb base side ring portion 26a is set to be smaller than the inner diameter of the thumb tip side ring portion 25a. Therefore, for example, in the case of a user with relatively thick fingers, the sizes of the ring finger tip side ring portion 16b and the thumb base side ring portion 26a can be easily adjusted by filing them down with a file or the like. This makes it possible to provide barber scissors 1 that are easy to grip for users with relatively thick fingers. Furthermore, since the first thickness-adding member 16 on which the ring finger tip side ring portion 16b is provided and the second thickness-adding member 26 on which the thumb base side ring portion 26a is provided are made of wood, they can be filed down more easily than metal materials.

[0084] Furthermore, the ring portion 15b on the base of the ring finger has a third notch 15f that connects the inner region and the outer region in the width direction of the ring portion 15b on the base of the ring finger, and the ring portion 16b on the tip of the ring finger has a fifth chamfered portion 16h that can come into contact with the user's ring finger. This makes it possible to increase the degree of freedom of the user's ring finger when the user grips the first handle member 12 and inserts it into the ring portion 15b on the base of the ring finger and the ring portion 16b on the tip of the ring finger. This makes it possible to improve the operability of the barber scissors 1 during barbering work.

[0085] Furthermore, the first fitting hole 15g of the first plate-shaped member 15 and the first fitting projection 16i of the first thickness-adding member 16 engage, and the second fitting hole 25e of the second plate-shaped member 25 and the second fitting projection 26f of the second thickness-adding member 26 engage, thereby enabling the positioning of the first plate-shaped member 15 and the first thickness-adding member 16, and the positioning of the second plate-shaped member 25 and the second thickness-adding member 26.

[0086] In Embodiment 2, an example was described in which the inner diameter of the ring portion 16b on the tip side of the ring finger is set to a smaller dimension than the inner diameter of the ring portion 15b on the base side of the ring finger. However, the inner diameters of the ring portion 16b on the tip side of the ring finger and the ring portion 15b on the base side of the ring finger may be set to the same dimension.

[0087] Furthermore, in Embodiment 2, an example was described in which the inner diameter of the thumb base side ring portion 26a is set to a smaller dimension than the inner diameter of the thumb tip side ring portion 25a. However, the inner diameters of the thumb base side ring portion 26a and the thumb tip side ring portion 25a may be set to the same dimension.

[0088] Furthermore, although Embodiment 2 described an example in which the ring portion 15b on the base side of the ring finger is provided with a third notch 15f, it is not necessary to provide this.

[0089] Furthermore, in Embodiment 2, the first thickness-adding member 16 was described using an example that includes a fifth chamfered portion 16h that can come into contact with the user's ring finger, but this portion is not required.

[0090] Furthermore, while Embodiment 2 described an example in which the first plate-shaped member 15 is provided with a first fitting hole 15g and the first fitting projection 16i of the first thickness-adding member 16 which can be fitted into the first fitting hole 15g, these are not required.

[0091] Furthermore, while Embodiment 2 described an example in which a second fitting hole 25e of the second plate-shaped member 25 and a second fitting projection 26f of the second thickness-adding member 26 that can be fitted into the second fitting hole 25e are provided, these may not be provided.
