FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The hairdressing scissors 1000 of the present invention will be described with reference to the drawings.

[0010] <1. Overall structure of hairdressing scissors> 1 to 3, the hairdressing scissors 1000 includes a first scissor member 10, a second scissor member 20, and a connecting member 30. The first scissor member 10 and the second scissor member 20 are rotatably connected to each other by the connecting member 30. The connecting member 30 includes, for example, a bolt, a nut, and a bearing. A known connecting member can be used as the connecting member 30.

[0011] In this embodiment, the first scissor member 10 is a moving blade and the second scissor member 20 is a stationary blade. When using the beauty scissors 1000, a user cuts hair by mainly moving the moving blade (first scissor member 10) while keeping the stationary blade (second scissor member 20) almost still.

[0012] The first scissors member 10 comprises a first blade portion 11, a first handle portion 12, and a first ring portion 13. The first blade portion 11 and the first handle portion 12 are integrally formed and cannot be separated from each other. The first handle portion 12 extends rearward beyond the connecting member 30. The first ring portion 13 is attached to the first handle portion 12. The first ring portion 13 comprises a first ring portion 131 and a connecting portion 132. When the hairdressing scissors 1000 are in use, the thumb is usually inserted into the first ring portion 131. The detailed structure of the first scissors member 10 will be described later.

[0013] The second scissors member 20 includes a second blade portion 21, a second handle portion 22, and a second ring portion 23. The second blade portion 21, the second handle portion 22, and the second ring portion 23 are integrally formed and cannot be separated from one another. The second blade portion 21, the second handle portion 22, and the second ring portion 23 are located on substantially the same plane. The second handle portion 22 extends rearward beyond the connecting member 30. The second ring portion 23 includes a second ring portion 231 and a finger hook portion 232. When the beauty scissors 1000 are in use, the ring finger is usually inserted into the second ring portion 231. Also, when the beauty scissors 1000 are in use, the little finger is usually hooked on the finger hook portion 232.

[0014] For ease of explanation, as shown in Fig. 2, the tip side of the first blade portion 11 and the second blade portion 21 is defined as the "front" of the beauty scissors 1000, the rear end side of the first ring portion 13 and the second ring portion 23 is defined as the "rear" of the beauty scissors 1000, the first ring portion 13 side is defined as the "left" of the beauty scissors 1000, and the second ring portion 23 side is defined as the "right" of the beauty scissors 1000. Also, as shown in Fig. 3, the direction in which the first blade portion 11 and the second blade portion 21 overlap when the beauty scissors 1000 is closed is defined as the "vertical direction" of the beauty scissors 1000 (the second blade portion 21 side is defined as the "upper" and the first blade portion 11 side is defined as the "lower").

[0015] <2. Structure of the first scissors member> As shown in Figures 1 to 4, the hairdressing scissors 1000 further includes a locking member 40, a first elastic member 50 (see Figure 4), an attachment member 60, a second elastic member 70 (see Figure 4), a hit point 80, and a retaining member 90.

[0016] 3 and 5, the first ring portion 13 is movable relative to the first handle portion 12. By moving the first ring portion 13, the position and orientation of the first ring portion 131 relative to the first handle portion 12 can be changed. The first ring portion 13 can be fixed (locked) at a predetermined position relative to the first handle portion 12 by a locking member 40.

[0017] In this embodiment, the first ring portion 13 is movable between a first position and a second position. When the first ring portion 13 is in the first position (see FIG. 3), the first ring portion 131 is located on approximately the same plane as the first blade portion 11 and the first handle portion 12. When the first ring portion 13 is in the second position (see FIG. 5), the first ring portion 131 is located lower than the first position. In this way, the first ring portion 13 is movable in the vertical direction between the first position and the second position.

[0018] <2-1. 1st handle> The first handle 12 will now be described with reference mainly to Figures 4, 6A, 6B, 9A and 9B.

[0019] 6A and 6B, the first handle 12 has a first hole 121, a second hole 122, and a third hole 123. The first handle 12 also has a first movement restricting portion 124 at the rear end of the first handle 12.

[0020] First hole 121 is recessed rightward from the left side surface of first handle 12. First hole 121 has a non-circular shape. A part of locking member 40 is disposed inside first hole 121 (see FIG. 4). A first through-hole 121a that penetrates the bottom of first hole 121 is provided at the bottom of first hole 121.

[0021] The second hole 122 is provided further rearward than the first hole 121. The second hole 122 is recessed rightward from the left side surface of the first handle 12. A part of the mounting member 60 is disposed within the second hole 122 (see FIG. 4).

[0022] A second through hole 122a is provided at the bottom of the second hole 122, penetrating the bottom of the second hole 122. A screw groove is provided on the inner surface of the second through hole 122a. A second mounting shaft 63 of the mounting member 60 is inserted into the second through hole 122a (see FIG. 4).

[0023] A first spring receiving portion 122b is provided rearward of the second through-hole 122a at the bottom of the second hole portion 122. The first spring receiving portion 122b is a hole provided at the bottom of the second hole portion 122. The first spring shaft portion 72 of the second elastic member 70 is inserted into the first spring receiving portion 122b (see FIG. 4).

[0024] Third hole 123 is recessed leftward from the right side surface of first handle 12. A screw groove is provided on the inner surface of third hole 123. Hit point 80 is screwed into the screw groove of third hole 123 (see FIG. 4).

[0025] The first movement restricting portion 124 cooperates with second movement restricting portions 136a and 136b (described later) to restrict the movement range (rotation range) of the first ring portion 13. The first movement restricting portion 124 is a protrusion protruding rearward from the rear end of the first handle portion 12. The first movement restricting portion 124 is disposed within a recess 136 of the first ring portion 13 (see FIGS. 9A and 9B).

[0026] <2-2. Locking member and first elastic member> The locking member 40 and the first elastic member 50 will now be described with reference mainly to FIGS.

[0027] The locking member 40 fixes the first ring portion 13 at the first position and the second position so that the first ring portion 13 cannot rotate relative to the first handle portion 12. The fixation (lock) by the locking member 40 can be released, and by releasing the lock, the first ring portion 13 becomes rotatable relative to the first handle portion 12.

[0028] 7, the locking member 40 includes a locking head 41, a first locking shaft portion 42, a second locking shaft portion 43, an extending portion 44, and a first lock engaging portion 45. The locking member 40 is movable in the direction of the central axes of the first locking shaft portion 42 and the second locking shaft portion 43.

[0029] The lock head 41 is disposed on the outside of the first handle 12 (see FIG. 4). The lock head 41 is a portion that is pressed by the user when releasing the lock.

[0030] The first lock shaft portion 42 extends from the lock head portion 41. A portion of the first lock shaft portion 42 is disposed within the first hole portion 121 (see FIG. 4).

[0031] The second lock shaft 43 has the same central axis as the first lock shaft 42 and extends from the first lock shaft 42. The outer diameter of the second lock shaft 43 is smaller than the outer diameter of the first lock shaft 42. Therefore, a step 46 exists between the first lock shaft 42 and the second lock shaft 43. The second lock shaft 43 is disposed in the first hole 121 and the first through hole 121a (see FIG. 4). The second lock shaft 43 has a screw hole. The retaining member 90 is, for example, a screw, and is screwed into the screw hole of the second lock shaft 43 (see FIG. 4). The head of the retaining member 90 is disposed outside the first handle 12 (more specifically, on the right side surface of the first handle 12). A retaining member 90 is attached to the second locking shaft 43 so that the head of the retaining member 90 is caught on the first handle 12, preventing the locking member 40 from coming off the first handle 12.

[0032] The first elastic member 50 is a member for automatically returning the locking member 40 to its original position by the restoring force of the first elastic member 50 after the locking member 40 is pushed toward the first handle 12. The first elastic member 50 is, for example, a spring, specifically a coil spring. The first elastic member 50 is attached around the second lock shaft 43 (see FIG. 4). The first elastic member 50 expands and contracts between the step 46 and the bottom of the first hole 121.

[0033] The extension portion 44 extends rearward from the first locking shaft portion 42. The extension portion 44 has a shape complementary to the first hole portion 121 (i.e., a non-circular columnar shape). The extension portion 44 is disposed in the first hole portion 121 so that there is almost no gap between the outer peripheral surface of the extension portion 44 and the inner peripheral surface of the first hole portion 121. The shape of the first hole portion 121 is non-circular, the shape of the extension portion 44 is non-circular columnar, and the extension portion 44 is disposed in the first hole portion 121 so that there is almost no gap between the outer peripheral surface of the extension portion 44 and the inner peripheral surface of the first hole portion 121, thereby preventing the locking member 40 from rotating with respect to the first handle portion 12.

[0034] The first lock engagement portion 45 extends from the rear of the extension portion 44 in the opposite direction to the second lock shaft portion 43. The first lock engagement portion 45 is a cylindrical protrusion. The first lock engagement portion 45 engages with a second lock engagement portion 133a of the first ring portion 13 (described later) (see FIG. 4), thereby fixing the first ring portion 13 at the first position. The first lock engagement portion 45 engages with a second lock engagement portion 133b of the first ring portion 13 (described later), thereby fixing the first ring portion 13 at the second position. The first lock engagement portion 45 is not limited to a cylindrical protrusion.

[0035] <2-3.First ring part> The first ring portion 13 will be described mainly with reference to Figs. 1, 4, 8A and 8B.

[0036] The connecting portion 132 is a portion for connecting the first ring portion 13 to the first handle portion 12. As shown in Figs. 8A and 8B, the connecting portion 132 has a plurality of second lock engagement portions 133 (133a, 133b), a plurality of second spring receiving portions 134, and an attachment member receiving portion 135. The connecting portion 132 is disposed on the left side surface of the first handle portion 12 (see Fig. 1). The first ring portion 13 also has a recess 136 between the connecting portion 132 and the first ring portion 131.

[0037] The second lock engagement portion 133a is a hole having a shape (circular in the present embodiment) complementary to the first lock engagement portion 45. When the first ring portion 13 is in the first position, the first lock engagement portion 45 is inserted into the second lock engagement portion 133a (see FIG. 4). As a result, the first ring portion 13 is fixed at the first position. The second lock engagement portion 133b is a hole having a shape (circular in the present embodiment) complementary to the first lock engagement portion 45. The second lock engagement portion 133b is provided below the second lock engagement portion 133a. When the first ring portion 13 is in the second position, the first lock engagement portion 45 is inserted into the second lock engagement portion 133b. As a result, the first ring portion 13 is fixed at the second position. The second lock engagement portions 133a and 133b may be through holes penetrating the connection portion 132. Furthermore, the second lock engagement portions 133a and 133b are not limited to circular holes.

[0038] The second spring receiving portions 134 (three in FIG. 8A) are circular holes. The second spring shaft portion 73 of the second elastic member 70 is inserted into one of the second spring receiving portions 134 (see FIG. 4).

[0039] The mounting member receiving portion 135 is a through hole that penetrates the connection portion 132. The first mounting shaft portion 62 of the mounting member 60 is inserted into the mounting member receiving portion 135 (see FIG. 4).

[0040] The recess 136 is recessed toward the rear. A first side wall that defines the recess 136 functions as a second movement restricting portion 136a. A second side wall that defines the recess 136 and is located on the opposite side to the first side wall functions as a second movement restricting portion 136b. The second movement restricting portions 136a and 136b cooperate with the first movement restricting portion 124 to restrict the movement range (rotation range) of the first ring portion 13. As shown in FIG. 9A, when the first ring portion 13 is in the first position, the second movement restricting portion 136a is in contact with the first movement restricting portion 124. Therefore, the first ring portion 13 cannot move upward any further. Also, as shown in FIG. 9B, when the first ring portion 13 is in the second position, the second movement restricting portion 136b is in contact with the first movement restricting portion 124. Therefore, the first ring portion 13 cannot move downward any further. In this manner, the rotation range of the first ring portion 13 is limited between the second movement restricting portion 136a and the second movement restricting portion 136b.

[0041] <2-4. Mounting member and second elastic member> The mounting member 60 and the second elastic member 70 will now be described with reference mainly to FIGS.

[0042] The mounting member 60 is a member for mounting the first ring portion 13 to the first handle portion 12. The mounting member 60 is mounted to the first handle portion 12 so that the central axis of the mounting member 60 is non-parallel (e.g., perpendicular) to the axial direction of the first handle portion 12. The central axis of the mounting member 60 becomes the rotation axis when the first ring portion 13 rotates. In other words, the first ring portion 13 rotates around the mounting member 60 with the mounting member 60 as the center.

[0043] 4, the mounting member 60 includes a mounting head 61, a first mounting shaft portion 62, and a second mounting shaft portion 63. As the mounting member 60, a general screw can be used.

[0044] The mounting head 61 is disposed on the left side surface of the connection portion 132 .

[0045] The first mounting shaft 62 extends from the mounting head 61. The first mounting shaft 62 is inserted into the mounting member receiving portion 135 (see FIG. 8A) of the first ring portion 13, and is disposed within the second hole portion 122 (see FIG. 4).

[0046] The second mounting shaft portion 63 has the same central axis as the first mounting shaft portion 62 and extends from the first mounting shaft portion 62. The outer diameter of the second mounting shaft portion 63 is smaller than the outer diameter of the first mounting shaft portion 62. A thread groove is provided on the outer surface of the second mounting shaft portion 63. The second mounting shaft portion 63 is screwed into the thread groove of the second through hole 122a of the first handle portion 12 (see FIG. 6A). In this way, the mounting member 60 is fixed to the first handle portion 12.

[0047] The hairdressing scissors 1000 include a return mechanism for returning the first ring portion 13 from the second position to the first position. The return mechanism may be a mechanism that automatically returns the first ring portion 13 from the second position to the first position. In this embodiment, the return mechanism includes a second elastic member 70. The second elastic member 70 is a member that uses its restoring force to automatically return the first ring portion 13 from the second position to the first position.

[0048] The second elastic member 70 is, for example, a spring. As shown in Fig. 10, the second elastic member 70 includes a spring body 71, a first spring shaft portion 72, and a second spring shaft portion 73. The spring body 71 is a coil spring. The first spring shaft portion 72 extends from the spring body 71 substantially parallel to the central axis of the spring body 71. The second spring shaft portion 73 extends from the spring body 71 in the opposite direction to the first spring shaft portion 72.

[0049] 4, the spring body 71 is disposed around the first mounting shaft portion 62. The first spring shaft portion 72 is inserted into the first spring receiving portion 122b of the first handle portion 12. The second spring shaft portion 73 is inserted into the second spring receiving portion 134 of the first ring portion 13.

[0050] <3. Procedure for moving the first ring part> The procedure for moving the first ring portion 13 will be described with reference to FIGS. 3, 4, 5, 9A, 9B, and 11.

[0051] The first ring portion 13 shown in Fig. 3 is disposed in the first position. As shown in Fig. 4, when the first ring portion 13 is in the first position, the first lock engagement portion 45 is inserted into the second lock engagement portion 133a. Also, as shown in Fig. 9A, when the first ring portion 13 is in the first position, the second movement restriction portion 136a is in contact with the first movement restriction portion 124.

[0052] As shown in FIG. 11, when the user presses the lock head 41 of the lock member 40, the lock member 40 moves toward the first handle 12, and the first lock engagement portion 45 is disengaged from the second lock engagement portion 133a. This releases the lock on the first ring portion 13, and the first ring portion 13 becomes rotatable relative to the first handle 12. The first elastic member 50 is compressed between the step 46 of the lock member 40 and the bottom of the first hole portion 121. While keeping the lock member 40 pressed, the user rotates the first ring portion 131 downward (i.e., clockwise in FIG. 3). The first ring portion 13 rotates around the central axis of the mounting member 60 and moves toward the second position (see FIG. 5). When the second movement restriction portion 136b comes into contact with the first movement restriction portion 124 (see FIG. 9B), the first ring portion 13 cannot rotate any further and stops at the second position.

[0053] When the user stops pressing the locking member 40 after moving the first ring portion 13 to the second position, the locking member 40 automatically returns due to the restoring force of the first elastic member 50, and the first lock engagement portion 45 is inserted into the second lock engagement portion 133b. When the first lock engagement portion 45 is inserted into the second lock engagement portion 133b, the first ring portion 13 becomes unable to rotate with respect to the first handle portion 12. In other words, the first ring portion 13 is fixed in the second position.

[0054] 3 and 5, the position and orientation of the first ring portion 131 in the second position are different from the position and orientation of the first ring portion 131 in the first position. Specifically, the rear end of the first ring portion 131 in the second position is located lower than the rear end of the first ring portion 131 and the first handle portion 12 in the first position. The first ring portion 131 is in an inclined position such that the rear end of the first ring portion 131 is located lower than the front end of the first ring portion 131.

[0055] Since the second spring shaft portion 73 of the second elastic member 70 is inserted into the second spring receiving portion 134 of the first ring portion 13 (see FIG. 4), when the first ring portion 13 is rotated to the second position, the second elastic member 70 is pulled by the first ring portion 13 and stretched. The stretched second elastic member 70 urges the first ring portion 13 toward the first position by its restoring force, but since the first ring portion 13 is fixed at the second position, it cannot rotate toward the first position.

[0056] When the locking member 40 is pressed again, the first lock engagement portion 45 is released from the second lock engagement portion 133b. This releases the lock on the first ring portion 13, and the first ring portion 13 becomes rotatable relative to the first handle portion 12. Then, due to the restoring force of the second elastic member 70, the first ring portion 13 automatically rotates upward (i.e., counterclockwise in FIG. 5) and returns to the first position. The second movement restriction portion 136a comes into contact with the first movement restriction portion 124 (see FIG. 9A), and the first ring portion 13 stops at the first position. When the user stops pressing the locking member 40, the locking member 40 automatically returns due to the restoring force of the first elastic member 50, and the first lock engagement portion 45 is inserted into the second lock engagement portion 133a. In this way, the first ring portion 13 is fixed at the first position.

[0057] <4. Effects> 3 and 5, in hairdressing scissors 1000, first ring portion 13 can be moved relative to first handle portion 12. This makes it possible to change the position and orientation of first ring portion 131 relative to first blade portion 11 and first handle portion 12. Therefore, the position and orientation of first ring portion 131 can be adjusted to a position and orientation that is easy for the user to use, making it easier for the user to cut hair.

[0058] The hairdressing scissors 1000 include a return mechanism that returns the first ring portion 13 from the second position to the first position, so that the first ring portion 13 can be returned to the second position.

[0059] Since the return mechanism includes the second elastic member 70, the first ring portion 13 can be automatically returned from the second position to the first position by the restoring force of the second elastic member 70. Therefore, the user can easily return the first ring portion 13 to the first position by simply releasing the lock by the lock member 40.

[0060] As shown in Fig. 8A, by providing a plurality of second spring receiving portions 134, the position into which the second spring shaft portion 73 of the second elastic member 70 is inserted can be changed. By changing the insertion position of the second spring shaft portion 73, the amount of elongation (i.e., the magnitude of the restoring force) of the second elastic member 70 when the first ring portion 13 is rotated can be changed. Therefore, by providing a plurality of second spring receiving portions 134, the restoring force of the second elastic member 70 can be adjusted, and therefore the rotation speed of the first ring portion 13 when the first ring portion 13 returns from the second position to the first position can be adjusted.

[0061] Since the first ring portion 13 can be fixed in a predetermined position by the locking member 40, it is possible to prevent the first ring portion 13 from moving unexpectedly while the hairdressing scissors 1000 are being used.

[0062] 7 and 8A, a combination of a first lock engagement part 45 and second lock engagement parts 133a, 133b with which the first lock engagement part 45 engages is employed as a mechanism for fixing the first ring part 13, thereby enabling stepwise position adjustment of the first ring part 13. In this embodiment, the second lock engagement part 133a corresponding to the first position and the second lock engagement part 133b corresponding to the second position are provided, so that the position of the first ring part 13 can be adjusted in two stages.

[0063] As shown in Figures 7 and 8A, by adopting a combination of a protrusion (first lock engagement portion 45) and a hole (second lock engagement portion 133a, 133b) into which the protrusion is inserted as a mechanism for fixing the first ring portion 13, a locking mechanism can be realized with a simple structure.

[0064] 11, when the user presses the locking member 40 to release the lock, the first elastic member 50 is compressed. Then, when the user stops pressing the locking member 40, the locking member 40 automatically returns due to the restoring force of the first elastic member 50, locking the first ring portion 13. Therefore, the user can easily fix the first ring portion 13 in a predetermined position by the locking member 40.

[0065] As shown in Fig. 9A, when the second movement restricting portion 136a contacts the first movement restricting portion 124, the second lock engaging portion 133a is aligned with the first lock engaging portion 45. Also, as shown in Fig. 9B, when the second movement restricting portion 136b contacts the first movement restricting portion 124, the second lock engaging portion 133b is aligned with the first lock engaging portion 45. In this manner, by providing the first movement restricting portion 124 and the second movement restricting portions 136a and 136b, it is possible to easily align the first lock engaging portion 45 with the second lock engaging portions 133a and 133b.

[0066] <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.
