[0009] The hairdressing scissors 1000 of the present invention will be described with reference to the drawings. Note that, in order to make the drawings easier to understand, if there are multiple components with the same structure, only some of those components may be denoted by reference numerals in the drawings.
[0010] <1. Overview of Hairdressing Scissors> As shown in Figure 1, the hairdressing scissors 1000 comprises a pair of scissor members 1100a and 1100b and a rotating mechanism 1200. Scissor member 1100a is a stationary blade. Scissor member 1100b is a moving blade. The rotating mechanism 1200 connects the pair of scissor members 1100a and 1100b so that they can rotate relative to each other to open and close. As shown in Figure 2, the rotating mechanism 1200 includes a bolt 1210, a nut 1220, a first washer 1230, and a second washer 1240. The rotating mechanism 1200 is not limited to this, and known rotating mechanisms can be used.
[0011] Since the pair of scissor members 1100a and 1100b have substantially the same components, unless otherwise specified, the descriptions of each component described below apply to both scissor members 1100a and 1100b.
[0012] As shown in Figures 1 and 2, the scissor members 1100a and 1100b each comprise a blade member 100, a handle member 200, and an angle changing mechanism 300. The angle changing mechanism 300 is a mechanism that changes 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 comparing Figures 1 and 3, the angle changing mechanism 300 of scissor member 1100a can change the angle between the blade member 100 and the handle member 200 of scissor member 1100a. Similarly, the angle changing mechanism 300 of scissor member 1100b can change the angle between the blade member 100 and the handle member 200 of scissor member 1100b. The angle between the blade member 100 and the handle member 200 can be changed by relatively rotating the blade member 100 and the handle member 200. The angle changing mechanism 300 can switch 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 component> As shown in Figure 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 for inserting a bolt 1210, located behind the blade 110.
[0014] The blade-side facing portion 120 is provided behind the through-hole 100a. The blade-side facing portion 120 is a portion that faces the handle-side facing portion 210 described later. 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 on the side opposite to the first surface 120a. The second surface 120b faces the handle-side facing portion 210.
[0015] The blade-side facing portion 120 has a cylindrical screw hole 121 at its approximate center. The blade-side facing portion 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 facing portion 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 elongate 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 made of a separate member from the blade member 100. As shown in FIGS. 1 and 2, the handle member 200 includes a handle-side opposing portion 210, a handle body 220, and a finger ring portion 230. The handle body 220 is a portion connecting the handle-side opposing portion 210 and the finger ring portion 230, and extends rearward from the handle-side opposing portion 210. The finger ring portion 230 is a portion where the user puts a finger when using the manicure scissors 1000. The finger ring portion 230 is coupled to the handle body 220. The handle member 200 of the stationary blade 1100a further includes a finger hook portion 240 on the finger ring portion 230. Each part constituting the handle member 200 of the blade member 1100a may be integrally and inseparably coupled. The handle member 200 of the blade member 1100b further includes a hit point 250 on the finger ring portion 230. Each part constituting the handle member 200 of the blade member 1100b may be integrally and inseparably coupled except for the hit point 250. The hit point 250 may be integrally and inseparably coupled to the finger ring portion 230, or may be detachable from the finger ring portion 230.
[0018] As shown in FIG. 2, the handle-side opposing portion 210 faces the blade-side opposing portion 120. The handle-side opposing portion 210 has a circular outer peripheral contour. The handle-side opposing portion 210 has a first surface 210a and a second surface 210b on the side opposite to the first surface 210a. The first surface 210a faces the blade-side opposing portion 120. The second surface 210b faces the regulation release member 350 described later.
[0019] The handle-side opposing portion 210 has a circular through hole 211 at its approximate center. The handle-side opposing portion 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] As shown in FIGS. 2 and 5, the handle-side opposing portion 210 has a through hole 213 at a position close to the handle body 220. The center of the through hole 213 is located on the same circumference as the centers of the two screw holes 212. The through hole 213 communicates with the concave portion 123.
[0021] As shown in Figure 2, the handle-side opposing 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 located on one side (the same side as the through hole 213) of the straight line connecting the centers of the two screw holes 212, and the remaining three through holes 214 are located on the other side of that straight line. As shown in Figure 6, each through hole 214 has a large-diameter portion 214a that opens toward the first surface 210a and a small-diameter portion 214b that opens toward the second surface 210b. The diameter of the small-diameter portion 214b is smaller than the diameter of the large-diameter portion 214a.
[0022] <2-3. Angle adjustment mechanism> As shown in Figure 2, the angle changing mechanism 300 includes a plurality of first elastic members 310 (three in this embodiment), a plurality of rotation restricting members 320 (three in this embodiment), a shaft member 330, a second elastic member 340, and a restriction release member 350.
[0023] As shown in Figure 7A, each first elastic member 310 is positioned within the recess 122. The same number of first elastic members 310 as the number of rotation restricting members 320 are provided. One axial end of each first elastic member 310 is in contact with the bottom of the recess 122. The other axial end of each first elastic member 310 is in contact with 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 Figure 7A, each rotation restricting member 320 comprises a cylindrical circumferential wall 321 and an end wall 322 that closes one end of the circumferential wall 321 in the direction of the central axis. The other end of the circumferential wall 321 in the direction of the central axis is open. The open end of the rotation restricting member 320 is inserted into the recess 122.
[0025] As shown in Figure 7A, a portion of the first elastic member 310 is positioned in the internal space of each rotation restricting member 320. When the 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 float above the bottom of the recess 122. As a result, each rotation restricting member 320 partially protrudes from the recess 122. The portion of each rotation restricting member 320 that protrudes from the recess 122 is inserted into the large-diameter portion 214a of the through-hole 214 of the handle-side opposing portion 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 portion 214a of the through-hole 214. Therefore, each rotation restricting member 320 is inserted into the recess 122 and the large-diameter portion 214a with virtually no gaps. Thus, when the release member 350 is not pressed, each rotation restricting member 320 is positioned to straddle both the recess 122 of the blade-side opposing part 120 and the through hole 214 of the handle-side opposing part 210. As a result, the blade member 100 and the handle member 200 cannot rotate relative to each other, and the scissor members 1100a and 1100b are fixed in place. Furthermore, since the outer diameter of the peripheral wall 321 is larger than the diameter of the small-diameter portion 214b of the through hole 214, the rotation restricting member 320 does not enter the small-diameter portion 214b.
[0026] As shown in Figure 7A, the shaft member 330 is inserted into the through hole 211 of the handle-side opposing portion 210 and is screw-connected to the screw hole 121 of the blade-side opposing portion 120. The shaft member 330 connects the blade-side opposing portion 120 and the handle-side opposing portion 210. The shaft member 330 has a circular recess 331. A second elastic member 340 is positioned within the recess 331. The second elastic member 340 elastically deforms when the release member 350 is pushed toward the blade member 100. When the release member 350 is no longer pushed toward the blade member 100, the second elastic member 340, with its restoring force, returns the release member 350 to its original position. The second elastic member 340 may be a compression coil spring.
[0027] The release member 350 is a component for switching the scissor members 1100a and 1100b from a fixed state to a rotatable state. The release member 350 is a separate component from the rotation restricting member 320. As shown in Figure 7B, by pressing the release member 350, the rotation restricting member 320 moves from the large-diameter portion 214a of the through hole 214 in the handle-side opposing portion 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 able to rotate relative to each other about the central axis of the shaft member 330.
[0028] As shown in Figures 2 and 7A, the de-restriction member 350 comprises a cylindrical circumferential wall 351 and an end wall 352 that closes one end of the circumferential wall 351 in the direction of the central axis. The other end of the circumferential wall 351 in the direction of the central axis is open.
[0029] As shown in Figure 7A, the inner diameter of the peripheral wall 351 is larger than the outer diameter of the handle-side opposing portion 210. As a result, the peripheral wall 351 is located radially outward from the outer circumference of the handle-side opposing portion 210. When the scissor members 1100a and 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 away from the blade member 100.
[0030] As shown in Figures 2 and 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 opposing portion 210. As shown in Figure 2, the end wall 352 has a plurality of through holes 352c (two in this embodiment) that penetrate the end wall 352. Each of the two through holes 352c is positioned to align with two screw holes 212. Screws 360 are inserted into each of the two through holes 352c. Each screw 360 is screw-connected to a screw hole 212 in the handle-side opposing portion 210. This prevents the release member 350 from coming off the handle-side opposing portion 210. The de-restriction release member 350 cannot move relative to the handle-side opposing portion 210 in a direction perpendicular to the central axis of the de-restriction release member 350, but it can move in a direction approaching the blade member 100 along the central axis of the de-restriction release member 350, and in a direction returning to its original position after approaching the blade member 100.
[0031] As shown in Figures 2 and 7A, the restriction release member 350 includes a plurality of release portions 353 (five in this embodiment), a limiting portion 354, and a pressing portion 355 on the 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 opposing portion 210. A portion of each release portion 353 is inserted into the small diameter portion 214b of the through hole 214 in the handle-side opposing portion 210. Three of the five release portions 353 each contact the end walls 322 of the three rotation restricting members 320. As shown in Figure 7B, when the restriction release member 350 is pushed toward the blade member 100, the release portion 353 pushes the rotation restricting member 320, moving the entire rotation restricting member 320 from the handle-side opposing portion 210 into the recess 122. This releases the fixed state of the scissor members 1100a and 1100b, and switches them 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 rotation of the relative rotation between the blade member 100 and the handle member 200. The range of rotation of the 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 Figure 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 Figure 4, the limiting portion 354 moves from one end to the other in the circumferential (longitudinal) direction of the recess 123 as the blade member 100 and the handle member 200 rotate relative to each other. In Figure 4, the limiting portion 354 after moving to the other end of the recess 123 is shown by a dashed line. When the blade member 100 and the handle member 200 rotate relative to each other, the limiting portion 354 comes into contact with the wall surface of either the circumferential end or the other end of the recess 123, preventing the blade member 100 and the handle member 200 from rotating relative to each other any further. Furthermore, when the limiting portion 354 is located at the circumferential end and the other end of the recess 123, the three through holes 214 of the handle-side opposing portion 210 and the three recesses 122 of the blade-side opposing portion 120 are aligned and in communication with each other.
[0035] As shown in Figures 2 and 7A, the pressing portion 355 is located approximately in the center of the first surface 352a of the end wall 352. The pressing portion 355 is cylindrical in shape. 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 is in contact with the second elastic member 340 within the recess 331.
[0036] <3. Procedure for changing the angle between the blade and the handle> Referring to Figures 1, 3, 7A, and 7B, the procedure for changing the angle between the blade member 100 and the handle member 200 will be described below. The procedure for rotating the handle member 200 relative to the blade member 100 from the first position shown in Figure 1 to the second position shown in Figure 3 will be described below.
[0037] As shown in Figure 7A, each rotation restricting member 320 is positioned to straddle the large-diameter portion 214a and the recess 122 of the through hole 214. Therefore, the scissor members 1100a and 1100b are fixed in place. Also, as shown in Figure 4, the limiting portion 354 is in contact with the wall surface of one end of the recess 123 in the circumferential direction.
[0038] When the user pushes the release member 350 toward the blade member 100, the pressing part 355 pushes the second elastic member 340, compressing it, as shown in Figure 7B. Also, when the user pushes the release member 350, the three release parts 353 push the rotation restricting members 320 in their corresponding positions toward the bottom of the recess 122. When each rotation restricting member 320 is completely detached from the large diameter portion 214a of the handle-side opposing portion 210, the lock between the blade member 100 and the handle member 200 is released, and the scissor members 1100a and 1100b become rotatable. In addition, the first elastic member 310 supporting each rotation restricting member 320 is pushed and compressed by each rotation restricting member 320. Note that each release part 353 does not enter the recess 122.
[0039] The user presses the release member 350 and rotates the handle member 200 relative to the blade member 100 until the limiting portion 354 contacts the wall surface of the other circumferential end of the recess 123. The handle member 200 rotates together with the release member 350 around the shaft member 330. By rotating the handle member 200 relative to the blade member 100, the angle between the blade member 100 and the handle member 200 can be changed to a different angle than before the rotation (see Figure 1), as shown in Figure 3. The angle between the blade member 100 and the handle member 200 in the second position (see Figure 3) is smaller than the angle between the blade member 100 and the handle member 200 in the first position (see Figure 1).
[0040] When the user stops pressing the release member 350, the restoring force of the compressed second elastic member 340 and the restoring force of the compressed first elastic member 310 causes the release member 350 to return to its original position. Also, the restoring force of the first elastic member 310 causes a portion of each rotation restricting member 320 to be inserted into the large diameter portion 214a of the through hole 214 located in a position aligned with them. As a result, each rotation restricting member 320 is again positioned to straddle both the recess 122 of the blade-side opposing portion 120 and the through hole 214 of the handle-side opposing portion 210, so that the scissor members 1100a and 1100b become fixed in place.
[0041] In the procedure described above, the handle member 200 was rotated relative to the blade member 100, but the blade member 100 may also be rotated relative to the handle member 200.
[0042] <4. Effects> In the hairdressing scissors 1000 of the present invention, the angle between the blade member 100 and the handle member 200 in the opening and closing direction of the hairdressing scissors 1000 can be changed. 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. As a result, the user of the hairdressing scissors 1000 can cut hair without twisting their wrist excessively.
[0043] The angle-changing mechanism 300 can be switched between a fixed state and a rotatable state. When necessary, the scissor members 1100a and 1100b can be made rotatable to change the angle between the blade member 100 and the handle member 200. On the other hand, when using the hairdressing scissors 1000, the scissor members 1100a and 1100b can be fixed to prevent the blade member 100 and the handle member 200 from rotating relative to each other unintentionally.
[0044] The angle adjustment mechanism 300 allows for stepwise adjustment of the angle between the blade member 100 and the handle member 200. In the above embodiment, adjustment is possible in two stages: the angle shown in Figure 1 and the angle shown in Figure 3.
[0045] After the rotation restricting member 320 disengages from the large-diameter portion 214a of the through-hole 214, when the user stops pressing the restriction release member 350, 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 way, the rotation restricting member 320 can be automatically returned by the first elastic member 310, so that the scissor members 1100a and 1100b can be automatically switched from a rotatable state to a fixed state.
[0046] When the user presses the release member 350, the second elastic member 340 undergoes elastic deformation. When the user stops pressing the release member 350, the release member 350 can automatically return to its original position due to the restoring force of the second elastic member 340.
[0047] The limiting mechanism allows for restricting the range of rotation of the relative rotation between the blade member 100 and the handle member 200.
[0048] By employing a combination of a recess 123 and a limiting portion 354 as the limiting mechanism, a 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 align with three of the five through holes 214. In this way, the limiting mechanism allows for alignment of the recesses 122 and the through holes 214. As a result, when switching the scissor members 1100a and 1100b from a rotatable state to a fixed state, a portion of the rotation restricting member 320 can be reliably inserted into the through holes 214.
[0050] <5. Variation> The present invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention. Modifications of the present invention are described below. The modifications described below can be applied to the above embodiments individually or in appropriate combinations without departing from the spirit of the invention.
[0051] (5-1) Only one of the scissor members 1100a or 1100b may be equipped with the angle changing mechanism 300. In this case, the blade member 100 and the handle member 200 of the scissor member 1100a or 1100b that is not equipped with the angle changing mechanism 300 do not need to have the blade-side opposing portion 120 and the handle-side opposing portion 210, respectively. Furthermore, the blade member 100 and the handle member 200 of the scissor member 1100a or 1100b that is not equipped with the angle changing mechanism 300 may not be made of separate parts but may be integrally joined together.
[0052] (5-2) In the above description, an embodiment was 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 Figure 1 and the angle shown in Figure 3). However, the angle between the blade member 100 and the handle member 200 may be set to three or more different angles.
[0053] (5-3) The handle member 200 may be rotatable with respect to the blade member 100 in the counterclockwise direction shown in Figure 1. Also, the direction of rotation of the handle member 200 with respect to the blade member 100 for the scissor member 1100a may be different from the direction of rotation of the handle member 200 with respect to the blade member 100 for the scissor member 1100b.
[0054] (5-4) The range of rotation of the relative rotation between the blade member 100 and the handle member 200 of the scissor member 1100a may be the same as or different from the range of rotation of the relative rotation between the blade member 100 and the handle member 200 of the scissor 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 embodiments, but can be set as appropriate. In one embodiment, there may be two rotation restricting members 320 and two first elastic members 310. Two rotation restricting members 320 can be inserted into recesses 122 that are symmetrically located with respect to the center of the screw hole 121 and into through holes 214 that are aligned with those recesses 122. Also, two first elastic members 310 can be placed in the same recesses 122 as the two rotation restricting members 320.
[0056] (5-6) When the rotation restricting member 320 returns to its original position, it pushes the release part 353. If the restoring force of the first elastic member 310 is large, the release part 353 is pushed 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 the release member 350.
