[0009] The hairdressing scissors 1000 of the present invention will be described with reference to the drawings. In order to make the drawings easier to understand, when there are a plurality of components with the same structure, only some of the components may be labeled with reference numerals in the drawings.
[0010] <1. Overview of hairdressing scissors> As shown in Fig. 1, the hairdressing scissors 1000 includes a pair of scissors members 1100a, 1100b and a rotation mechanism 1200. The scissors member 1100a is a stationary blade. The scissors member 1100b is a moving blade. The rotation mechanism 1200 connects the pair of scissors members 1100a, 1100b so that the pair of scissors members 1100a, 1100b can rotate relative to each other to open and close. As shown in Fig. 2, the rotation mechanism 1200 includes a bolt 1210, a nut 1220, a first washer 1230, and a second washer 1240. The rotation mechanism 1200 is not limited thereto, and any known rotation mechanism can be used.
[0011] Since the pair of scissor members 1100a, 1100b have substantially the same components, the following description of each component applies to both scissor members 1100a, 1100b unless otherwise specified.
[0012] As shown in Fig. 1 and Fig. 2, each of the scissors members 1100a and 1100b includes a blade member 100, a handle member 200, and an angle change mechanism 300. The angle change mechanism 300 is a mechanism for changing the angle between the blade member 100 and the handle member 200 in the opening and closing direction of the hairdressing scissors 1000. As can be seen from a comparison between Fig. 1 and Fig. 3, the angle between the blade member 100 and the handle member 200 of the scissors member 1100a can be changed by the angle change mechanism 300 of the scissors member 1100a. In addition, the angle between the blade member 100 and the handle member 200 of the scissors member 1100b can be changed by the angle change mechanism 300 of the scissors member 1100b. The angle between the blade member 100 and the handle member 200 can be changed by rotating the blade member 100 and the handle member 200 relative to each other. The angle change mechanism 300 can be switched between a fixed state in which relative rotation between the blade member 100 and the handle member 200 is prohibited, and a rotatable state in which relative rotation between the blade member 100 and the handle member 200 is permitted.
[0013] <2-1.Blade material> 2, the blade member 100 has a blade 110 and a blade-side opposing portion 120. The blade member 100 has a through hole 100a behind the blade 110 into which a bolt 1210 is inserted.
[0014] The blade side facing portion 120 is provided behind the through hole 100a. The blade side facing portion 120 faces the handle side facing portion 210 described below. The blade side facing portion 120 has a circular outer peripheral contour. The blade side facing portion 120 has a first surface 120a and a second surface 120b opposite to the first surface 120a. The second surface 120b faces the handle side facing portion 210.
[0015] The blade side opposing part 120 has a cylindrical screw hole 121 at approximately its center. The blade side opposing part 120 has a plurality of cylindrical recesses 122 (three in this embodiment) around the screw hole 121. Each recess 122 is recessed from the second surface 120b toward the first surface 120a. Each recess 122 does not penetrate the blade side opposing part 120 and has a bottom. Two of the three recesses 122 are provided symmetrically with respect to the center of the screw hole 121. The centers of the three recesses 122 are located on a circumference concentric with the screw hole 121.
[0016] The blade side facing portion 120 has a curved recess 123 around the screw hole 121. The recess 123 is elongated and extends in the circumferential direction of the screw hole 121. The recess 123 is recessed from the second surface 120b toward the first surface 120a. The recess 123 does not penetrate the blade side facing portion 120 and has a bottom. The center line of the recess 123 is located on the same circumference as the center of the recess 122. In this embodiment, the central angle α (see FIG. 4) of the recess 123 is approximately 45 degrees. Note that the central angle α of the recess 123 is not limited to 45 degrees.
[0017] <2-2. Handle member> The handle member 200 is a separate member from the blade member 100. As shown in FIG. 1 and FIG. 2, the handle member 200 includes a handle-side facing portion 210, a handle body 220, and a finger ring portion 230. The handle body 220 is a portion that connects the handle-side facing portion 210 and the finger ring portion 230, and extends rearward from the handle-side facing portion 210. The finger ring portion 230 is a portion into which a user inserts his or her finger when using the hairdressing scissors 1000. The finger ring portion 230 is connected to the handle body 220. The handle member 200 of the scissors member 1100a, which is a stationary blade, further includes a finger hook portion 240 on the finger ring portion 230. The respective portions that constitute the handle member 200 of the scissors member 1100a may be connected inseparably as a single unit. The handle member 200 of the scissors member 1100b further includes a hit point 250 on the finger ring portion 230. Each part constituting the handle member 200 of the scissors member 1100b may be integrally and inseparably connected, except for the hit point 250. The hit point 250 may be integrally and inseparably connected to the ring portion 230, or may be detachable from the ring portion 230.
[0018] As shown in Fig. 2, the handle side facing part 210 faces the blade side facing part 120. The handle side facing part 210 has a circular outer peripheral contour. The handle side facing part 210 has a first surface 210a and a second surface 210b opposite to the first surface 210a. The first surface 210a faces toward the blade side facing part 120. The second surface 210b faces toward the restriction release member 350 described below.
[0019] The handle side facing part 210 has a circular through hole 211 at approximately the center thereof. The handle side facing part 210 has a plurality of screw holes 212 (two in this embodiment) around the through hole 211. The two screw holes 212 are provided symmetrically with respect to the center of the through hole 211. The centers of the two screw holes 212 are located on a circumference concentric with the through hole 211.
[0020] 2 and 5, handle side facing part 210 has a through hole 213 at a position close to handle body 220. The center of through hole 213 is located on the same circumference as the centers of two screw holes 212. Through hole 213 communicates with recess 123.
[0021] As shown in FIG. 2, the handle-side facing portion 210 has a plurality of through holes 214 (five in this embodiment). The center of each through hole 214 is located on the same circumference as the centers of the two screw holes 212. Two of the five through holes 214 are provided on one side (the same side as the through hole 213) of a line connecting the centers of the two screw holes 212, and the remaining three through holes 214 are provided on the other side of the line. As shown in FIG. 6, each through hole 214 has a large diameter portion 214a that opens on the first surface 210a side and a small diameter portion 214b that opens on the second surface 210b side. The diameter of the small diameter portion 214b is smaller than the diameter of the large diameter portion 214a.
[0022] <2-3. Angle change mechanism> As shown in FIG. 2, the angle change mechanism 300 includes a plurality of first elastic members 310 (three in this embodiment), a plurality of rotation restriction members 320 (three in this embodiment), an axis member 330, a second elastic member 340, and a restriction release member 350.
[0023] 7A, each first elastic member 310 is disposed in the recess 122. The number of first elastic members 310 provided is the same as the number of rotation restricting members 320. One axial end of each first elastic member 310 contacts the bottom of the recess 122. The other axial end of each first elastic member 310 contacts the rotation restricting member 320. The first elastic members 310 may be compression coil springs.
[0024] Each rotation restricting member 320 restricts the relative rotation between the blade member 100 and the handle member 200. As shown in Fig. 7A, each rotation restricting member 320 includes a cylindrical peripheral wall 321 and an end wall 322 closing one end of the peripheral wall 321 in the central axis direction. The other end of the peripheral wall 321 in the central axis direction is open. The open end of the rotation restricting member 320 is inserted into the recess 122.
[0025] As shown in FIG. 7A, a part of the first elastic member 310 is disposed in the internal space of each rotation restricting member 320. When the restriction release member 350 is not pressed toward the blade member 100, each rotation restricting member 320 is supported by the first elastic member 310 so as to be in a state of being floating from the bottom of the recess 122. As a result, each rotation restricting member 320 partially protrudes from the recess 122. The part of each rotation restricting member 320 protruding from the recess 122 is inserted into the large diameter part 214a of the through hole 214 of the handle side facing part 210. The outer diameter of the peripheral wall 321 is slightly smaller than the diameter of the recess 122 and the diameter of the large diameter part 214a of the through hole 214. Therefore, each rotation restricting member 320 is inserted into the recess 122 and the large diameter part 214a with almost no gap. In this way, when the restriction release member 350 is not pressed, each rotation restriction member 320 is disposed across both the recess 122 of the blade side opposing part 120 and the through hole 214 of the handle side opposing part 210, so that the blade member 100 and the handle member 200 cannot rotate relative to each other, and the scissors members 1100a, 1100b are fixed. Note that, since the outer diameter of the peripheral wall 321 is larger than the diameter of the small diameter part 214b of the through hole 214, the rotation restriction member 320 does not enter the small diameter part 214b.
[0026] As shown in FIG. 7A, the shaft member 330 is inserted into the through hole 211 of the handle side facing part 210 and is screwed into the screw hole 121 of the blade side facing part 120. The shaft member 330 connects the blade side facing part 120 and the handle side facing part 210. The shaft member 330 has a circular recess 331. A second elastic member 340 is disposed in the recess 331. The second elastic member 340 is elastically deformed when the restriction release member 350 is pressed toward the blade member 100. When the restriction release member 350 is no longer pressed toward the blade member 100, the second elastic member 340 returns the restriction release member 350 to its original position by its restoring force. The second elastic member 340 may be a compression coil spring.
[0027] The restriction release member 350 is a member for switching the scissors members 1100a, 1100b from a fixed state to a rotatable state. The restriction release member 350 is a member separate from the rotation restricting member 320. As shown in Fig. 7B, by pushing the restriction release member 350, the rotation restricting member 320 moves from the large diameter portion 214a of the through hole 214 of the handle side opposing part 210 into the recess 122. As a result, the lock by the rotation restricting member 320 is released, and the blade member 100 and the handle member 200 become relatively rotatable around the central axis of the shaft member 330.
[0028] 2 and 7A, the deregulation member 350 includes a cylindrical peripheral wall 351 and an end wall 352 that closes one end in the central axis direction of the peripheral wall 351. The other end in the central axis direction of the peripheral wall 351 is open.
[0029] 7A, the inner diameter of the peripheral wall 351 is larger than the outer diameter of the handle side facing part 210. As a result, the peripheral wall 351 is located radially outward from the outer periphery of the handle side facing part 210. When the scissors members 1100a, 1100b are in a fixed state, the open end of the peripheral wall 351 is not in contact with the blade member 100 and is floating above the blade member 100.
[0030] As shown in FIG. 2 and FIG. 7A, the end wall 352 has a first surface 352a and a second surface 352b opposite to the first surface 352a. The first surface 352a faces the handle side facing part 210. As shown in FIG. 2, the end wall 352 has a plurality of through holes 352c (two in this embodiment) penetrating the end wall 352. The two through holes 352c are provided at positions aligned with the two screw holes 212, respectively. A screw 360 is inserted into each of the two through holes 352c. Each screw 360 is screwed into the screw hole 212 of the handle side facing part 210. This prevents the restriction release member 350 from coming off the handle side facing part 210. In addition, the deregulation member 350 cannot move relative to the handle side opposing portion 210 in a direction perpendicular to the central axis of the deregulation member 350, but can move along the central axis of the deregulation member 350 in a direction approaching the blade member 100, and in a direction returning to its original position after approaching the blade member 100.
[0031] As shown in FIGS. 2 and 7A, the restriction release member 350 includes a plurality of release portions 353 (five in this embodiment), a restriction portion 354, and a pressing portion 355 on a first surface 352a of the end wall 352.
[0032] Each release portion 353 is cylindrical. Each release portion 353 extends from the first surface 352a of the end wall 352 toward the handle-side facing portion 210. A portion of each release portion 353 is inserted into the small diameter portion 214b of the through hole 214 of the handle-side facing portion 210. Three of the five release portions 353 are in contact with the end walls 322 of the three rotation restriction members 320. As shown in FIG. 7B, when the restriction release member 350 is pushed toward the blade member 100, the release portion 353 pushes the rotation restriction member 320 to move the entire rotation restriction member 320 from the handle-side facing portion 210 into the recess 122. As a result, the fixed state of each of the scissors members 1100a and 1100b is released, and each of the scissors members 1100a and 1100b is switched to a rotatable state.
[0033] The limiting portion 354, together with the recess 123, constitutes a limiting mechanism. The limiting mechanism is a mechanism that limits the range of relative rotation between the blade member 100 and the handle member 200. The range of relative rotation between the blade member 100 and the handle member 200 is the same as the central angle α of the recess 123, for example, 45 degrees. As shown in FIG. 5, the limiting portion 354 is cylindrical. The limiting portion 354 extends from the first surface 352a of the end wall 352 through the through hole 213 of the handle side opposing portion 210 into the recess 123.
[0034] As shown in FIG. 4, the limiting portion 354 moves from one end to the other end in the circumferential direction (longitudinal direction) of the recess 123 in association with the relative rotation of the blade member 100 and the handle member 200. In FIG. 4, the limiting portion 354 after moving to the other end of the recess 123 is shown by a broken line. When the blade member 100 and the handle member 200 are rotated relative to each other, the limiting portion 354 comes into contact with the wall surface of one end or the wall surface of the other end of the circumferential direction of the recess 123, so that the blade member 100 and the handle member 200 cannot rotate relative to each other any further. In addition, when the limiting portion 354 is located at one end or the other end of the circumferential direction of the recess 123, the three through holes 214 of the handle side facing portion 210 and the three recesses 122 of the blade side facing portion 120 are aligned and communicated with each other.
[0035] 2 and 7A, the pressing portion 355 is provided at approximately the center of the first surface 352a of the end wall 352. The pressing portion 355 is cylindrical. The pressing portion 355 extends from the first surface 352a of the end wall 352 toward the shaft member 330. The tip of the pressing portion 355 is inserted into the recess 331 of the shaft member 330 and contacts the second elastic member 340 inside the recess 331.
[0036] <3. Procedure for changing the angle between the blade and handle> 1, 3, 7A and 7B, a procedure for changing the angle between the blade member 100 and the handle member 200 will be described. Below, a procedure for rotating the handle member 200 relative to the blade member 100 from a first position shown in Fig. 1 to a second position shown in Fig. 3 will be described.
[0037] As shown in Fig. 7A, each rotation restriction member 320 is disposed across the large diameter portion 214a of the through hole 214 and the recess 122. Therefore, the scissors members 1100a and 1100b are each in a fixed state. In addition, as shown in Fig. 4, the limiting portion 354 contacts the wall surface of one end of the recess 123 in the circumferential direction.
[0038] When the user presses the deregulation member 350 toward the blade member 100, the pressing portion 355 presses the second elastic member 340 and compresses the second elastic member 340, as shown in FIG. 7B. When the user presses the deregulation member 350, the three release portions 353 press the rotation restriction members 320 at the corresponding positions toward the bottom of the recess 122. When each rotation restriction member 320 is completely detached from the large diameter portion 214a of the handle side facing portion 210, the lock between the blade member 100 and the handle member 200 is released, and the scissors members 1100a, 1100b become rotatable. In addition, the first elastic member 310 supporting each rotation restriction member 320 is pressed by each rotation restriction member 320 and compressed. Note that each release portion 353 does not enter the recess 122.
[0039] While pressing the deregulation member 350, the user rotates the handle member 200 relative to the blade member 100 until the limiting portion 354 comes into contact with the wall surface of the other end of the recess 123 in the circumferential direction. The handle member 200 rotates around the shaft member 330 together with the deregulation member 350. By rotating the handle member 200 relative to the blade member 100, as shown in FIG. 3, the angle between the blade member 100 and the handle member 200 can be changed to an angle different from that before the rotation (see FIG. 1). The angle between the blade member 100 and the handle member 200 in the second position (see FIG. 3) is smaller than the angle between the blade member 100 and the handle member 200 in the first position (see FIG. 1).
[0040] When the user stops pressing the restriction release member 350, the restriction release member 350 returns to its original position due to the restoring force of the compressed second elastic member 340 and the restoring force of the compressed first elastic member 310. Also, due to the restoring force of the first elastic member 310, a part of each rotation restriction member 320 is inserted into the large diameter portion 214a of the through hole 214 that exists in a position that matches the rotation restriction member 320. Therefore, each rotation restriction member 320 is again arranged straddling both the recess 122 of the blade side opposing part 120 and the through hole 214 of the handle side opposing part 210, so that the scissors members 1100a, 1100b are in a fixed state.
[0041] In the above procedure, the handle member 200 is rotated relative to the blade member 100, but the blade member 100 may be rotated relative to the handle member 200.
[0042] <4. Effects> In the beauty scissors 1000 of the present invention, the angle between the blade member 100 and the handle member 200 can be changed in the opening and closing direction of the beauty scissors 1000. Therefore, the angle between the blade member 100 and the handle member 200 can be changed to an angle that is easy for the user to use. This allows the user of the beauty scissors 1000 to cut hair without having to twist their wrist significantly.
[0043] Because angle-changing mechanism 300 can be switched between a fixed state and a rotatable state, scissor members 1100a, 1100b can each be set to a rotatable state when necessary to change the angle between blade member 100 and handle member 200. On the other hand, when using hairdressing scissors 1000, scissor members 1100a, 1100b can each be set to a fixed state to prevent unexpected relative rotation between blade member 100 and handle member 200.
[0044] The angle changing mechanism 300 allows stepwise adjustment of the angle between the blade member 100 and the handle member 200. In the above embodiment, the angle can be adjusted in two stages, the angle shown in FIG. 1 and the angle shown in FIG.
[0045] When the user stops pressing the restriction release member 350 after the rotation restricting member 320 has been released from the large diameter portion 214a of the through hole 214, a portion of the rotation restricting member 320 is automatically inserted into the large diameter portion 214a by the restoring force of the first elastic member 310. In this manner, the rotation restricting member 320 can be automatically restored by the first elastic member 310, so that the scissors members 1100a, 1100b can each be automatically switched from the rotatable state to the fixed state.
[0046] When the user presses the derestriction member 350, the second elastic member 340 is elastically deformed. When the user stops pressing the derestriction member 350, the derestriction member 350 can automatically return to its original position due to the restoring force of the second elastic member 340.
[0047] By providing the limiting mechanism, the range of relative rotation between the blade member 100 and the handle member 200 can be limited.
[0048] By employing a combination of the recess 123 and the limiting portion 354 as the limiting mechanism, the limiting mechanism can be realized with a simple configuration.
[0049] When the limiting portion 354 is located at one end and the other end of the recess 123 in the circumferential direction, the three recesses 122 are aligned with three of the five through holes 214. In this manner, the recesses 122 can be aligned with the through holes 214 by the limiting mechanism. As a result, when the scissors members 1100a, 1100b are switched from the rotatable state to the fixed state, a portion of the rotation restricting member 320 can be reliably inserted into the through holes 214.
[0050] <5. Modifications> The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the scope of the present invention. Modifications of the present invention will be described below. The modifications described below can be applied to the above-described embodiment alone or in appropriate combination without departing from the scope of the present invention.
[0051] (5-1) Only one of the scissors member 1100a or the scissors member 1100b may be provided with the angle changing mechanism 300. In this case, the blade member 100 and the handle member 200 of the scissors member 1100a or the scissors member 1100b not provided with the angle changing mechanism 300 may not have the blade side opposing portion 120 and the handle side opposing portion 210, respectively. In addition, the blade member 100 and the handle member 200 of the scissors member 1100a or the scissors member 1100b not provided with the angle changing mechanism 300 may not be made of separate members but may be inseparably connected to one another.
[0052] (5-2) In the above, an embodiment has been described in which the angle between the blade member 100 and the handle member 200 can be set to two different angles (the angle shown in FIG. 1 and the angle shown in FIG. 3), but the angle between the blade member 100 and the handle member 200 may also be set to three or more different angles.
[0053] (5-3) The handle member 200 may be rotatable in a counterclockwise direction in Fig. 1 relative to the blade member 100. Furthermore, the rotation direction of the handle member 200 relative to the blade member 100 of the scissors member 1100a may be different from the rotation direction of the handle member 200 relative to the blade member 100 of the scissors member 1100b.
[0054] (5-4) The range of relative rotation between the blade member 100 and the handle member 200 of the scissors member 1100a may be the same as or different from the range of relative rotation between the blade member 100 and the handle member 200 of the scissors member 1100b.
[0055] (5-5) The number of each component, such as the number of rotation restricting members 320 and the number of first elastic members 310, is not limited to the numbers mentioned in the above embodiment, and may be set appropriately. In one embodiment, there may be two each of the rotation restricting members 320 and the first elastic members 310. The two rotation restricting members 320 may be inserted into recesses 122 located symmetrically with respect to the center of the screw hole 121 and into the through holes 214 aligned with the recesses 122. In addition, the two first elastic members 310 may be disposed in the same recess 122 as the two rotation restricting members 320.
[0056] (5-6) When the rotation restricting member 320 returns to its original position, the rotation restricting member 320 presses the release portion 353. If the restoring force of the first elastic member 310 is large, the release portion 353 is pressed by the rotation restricting member 320, and the restriction release member 350 can also automatically return to its original position. Therefore, if the restriction release member 350 can return to its original position by the restoring force of the first elastic member 310, the second elastic member 340 is not necessarily required.
[0057] (5-7) The restricting portion 354 may be provided on the handle side opposing portion 210 instead of on the deregulation member 350.
