(Detail structure)
1. Appearance of the substrate 10 The bottom surface of the substrate 10 is flat and configured to be able to stand on the desk or the floor. Moreover, the base | substrate 10 is formed in the magnitude | size which can be held with one hand. At the rear end portion of the base body 10, a finger hooking portion 10a for hooking an index finger, a middle finger, a ring finger, and a little finger is formed.
A disc 5 is provided on the front surface of the base 10, and a knob 5 a is provided at an eccentric position of the disc 5. In addition, a rotating body 11 is provided at the upper front portion of the base body 10, and three base-side thread locking portions (second thread locking portions) 3 a to 3 c protrude upward from the rotating body 11. Yes.
In use, the bottom surface of the base body 10 is pressed against the floor surface by grasping the base body 10 with one hand (for example, the left hand) with its wrist raised. Then, the knob 5a is rotated with the other hand (for example, the right hand). In this case, when the knob 5a is rotated in the clockwise direction when viewed from the front side, the three base-side thread locking portions (second thread locking portions) 3a to 3c rotate, and conversely, the knob 5a is moved to the front side. When rotating counterclockwise as viewed from the top, the three base-side thread locking portions 3a to 3c revolve around a predetermined axis.

2. Structure of Rotating Device 20 The rotating device 20 is for rotating and revolving the three base-side thread locking portions 3a to 3c in accordance with the operation of the knob 5a.
As shown in FIGS. 2 and 3, a bevel gear 51 is attached to the shaft 5 b of the disk 5. Then, the rotational power of the disk 5 is transmitted to the bevel gear 51 via the torque limiter 52 (FIG. 3).
That is, the member 53 is fixed to the shaft 5 b of the disk 5 at a position away from the disk 5 by a predetermined distance. Further, a bevel gear 51 and a surface gear 54 having a gear formed on the end face are axially supported on the shaft 5 b of the disk 5, and a coil 5 is provided on the shaft 5 b between the surface gear 54 and the member 53. A spring 55 is wound around. On the other hand, an inward flange is formed at the front end of the shaft cylinder 51a of the bevel gear 51, and a surface gear 51b that can mesh with the surface gear 54 is formed on the flange. The surface gear 51b, the surface gear 54, and the coil spring 55 constitute a torque limiter 52. The surface gear 51b and the surface gear 54 are normally engaged with each other by the urging force of the coil spring 55, and the surface gear 51b and the surface gear 54 are engaged. When an overload is applied between the face gear 51b and the face gear 54, the face gear 51b and the face gear 54 are separated from each other against the urging force of the coil spring 55 to interrupt power transmission.

  The bevel gear 51 meshes with a bevel gear 61 attached to the lower end of a shaft 61a that is orthogonal to the shaft 5b and extends in the vertical direction. The shaft 61a of the bevel gear 61 extends from below to the fixing member 10c through the fixing member 10c of the base body 10, and a rotating body 62 is fixedly provided at the upper end of the shaft 61a. An internal gear 62 a is formed on the upper surface side of the rotating body 62. The internal gear 62a meshes with each of the small gears 30 formed at the lower ends of the three base-side thread locking portions 3a to 3c. The three base-side thread locking portions 3a to 3c are provided at eccentric positions of the rotating body 62 and at equal intervals in the circumferential direction.

Between the fixed member 10 c and the rotating body 62, a rotating body 63 that can rotate about the shaft 61 a of the bevel gear 61 is provided. Claw gears 63 a and 63 b are formed on the upper surface side and the lower surface side of the rotating body 63. As shown in the top view of FIG. 5, the claw member 64 fitted in the eccentric position to the pins 62 a and 62 a formed on the lower surface of the rotating body 62 is engaged with the claw gear 63 a on the upper surface side of the rotating body 63. ing. The claw gear 63a and the claw member 64 constitute a one-way clutch. On the other hand, as shown in the bottom view of FIG. 6, the claw gear 65 on the lower surface side of the rotating body 63 has a claw member 65 that fits in an eccentric position to the pins 100a and 100a formed on the lower surface of the fixing member 10c. Match. The claw gear 63b and the claw member 65 constitute a one-way clutch.
In addition, the rotating body 11 is fixed to the rotating body 63 so as to be rotatable about the shaft 61a. The rotating body 11 is formed in a bowl shape and covers the outer periphery of the rotating body 63 and the outer periphery and the upper side of the rotating body 62. The rotating body 11 is formed with three holes 11a to 11c at eccentric positions, and three base-side thread locking portions 3a to 3c protrude upward one by one from the three holes 11a to 11c.

3. Action of the Rotating Device 20 When the knob 5a is rotated clockwise in front view, the bevel gear 61 and the rotating body 62 rotate counterclockwise in top view. Then, on the lower surface side of the rotating body 63, the tips of the arc-shaped elastic pieces 65a and 65a of the claw member 65 abut between the claw teeth of the claw gear 63b, so that the rotation of the rotating body 63 is prevented. However, on the upper surface side of the rotating body 63, the claw teeth of the claw gear 63a are traced by the back surfaces of the arc-shaped elastic pieces 64a, 64a of the claw member 64, and the arc-shaped elastic pieces 63a, 63a escape, so that the rotation of the rotating body 62 is hindered. I can't. At this time, since the rotating body 62 rotates following the bevel gear 61 and the rotating body 11 does not rotate, the three base-side thread locking portions 3a to 3c are centered on their own axes (predetermined axes). It rotates (spins) on the spot.
On the other hand, when the knob 5a is rotated counterclockwise when viewed from the front, the bevel gear 61 and the rotating body 62 are rotated clockwise when viewed from the top. Then, on the upper surface side of the rotating body 63, the tips of the arc-shaped elastic pieces 64a and 64a of the claw member 64 abut between the claw teeth of the claw gear 63a. On the other hand, on the lower surface side of the rotating body 63, the claw teeth of the claw gear 63b are traced by the back surfaces of the arc-shaped elastic pieces 65a and 65a of the claw member 65 so that the arc-shaped elastic pieces 64a and 64a escape. Permissible. At this time, since the rotating body 62 rotates following the bevel gear 61, the rotating body 11 also rotates in the same direction, so that the three base-side thread locking portions 3a to 3c rotate (revolve) around the shaft 61a. )
Thus, the rotating device 20 includes switching means for switching between rotation and revolution, and switches between rotation and revolution according to the rotation direction of the knob 5a.

4). Substrate side thread locking portions 3a to 3c
The base-side thread locking portions 3a to 3c are all formed in the same shape. Therefore, the shape of the base-side thread locking portion 3a will be described, and the description of the base-side thread locking portions 3b and 3c will be omitted.
As shown in FIG. 7, the base-side thread locking portion 3a is formed in a column shape. A locking piece 31 is formed at the upper end by biting. This locking piece 31 is a hook, and is configured to be able to lock a folded portion of a thread folded in two from below.
In addition, a disk part projecting outward in the radial direction is formed at the lower end of the base-side thread locking part 3a, and a small gear 30 is formed in this disk part. The small gear 30 meshes with the internal gear 62a as described above.

5. Thread support member 4
The yarn support member 4 erected on the rear upper surface of the base body 10 is formed of three column portions 41, 42, 43. The three column parts 41, 42, 43 are assembled in a nested manner. That is, the three column portions 41, 42, and 43 are each formed in a U-shaped cross section, and the cross-sectional sizes are reduced in the order of the column portions 41, 42, and 43 from the lower side. A column portion 42 is arranged inside the column portion 41, and a column portion 43 is arranged inside the column portion 42. And the upper column part among the column parts adjacent in the up-down direction is configured to be able to appear and disappear with respect to the lower column part. As a result, the thread support member 4 is configured to be extendable in the vertical direction as a whole.
Further, elastic pieces 42 a and 43 a are formed near the lower ends of the column portions 42 and 43. The elastic pieces 42a and 43a are partitioned by U-shaped slits (not shown), and convex portions are formed on the outer surfaces of the elastic pieces 42a and 43a. The convex portions engage with the inner surfaces of the column portions 41 and 42 immediately below by elastic force, so that the column portions 42 and 43 are fixed at an arbitrary height position.
Further, the column portion 41 is configured to be able to project and retract with respect to the base body 10, and a coil spring 44 (see FIG. 2) is provided between the lower end portion of the column portion 41 and the floor plate of the base body 10. The yarn support member 4 is biased upward by 44.

Further, as shown in FIG. 9, a rectangular plate-like thread locking member 40 that projects in the front-rear direction and in the horizontal direction is provided at the upper end portion of the uppermost column portion 43. The thread support member 40 is formed with support member side thread locking portions 4a to 4c. Each of the support member-side thread locking portions 4a to 4c has a shape obtained by modifying the “Y” shape. That is, each of the support member side thread locking portions 4a to 4c is formed by a pair of sandwiching pieces in a straight rod shape or a flat plate shape, and a thread guide portion on the tip side of each sandwiching piece. The pair of sandwiching pieces has a shape in which one surface is in contact with each other, and an arcuate thread guide portion is integrally formed on the tip side of each of the pair of sandwiching pieces. And these thread | guide guide parts have the shape expanded toward the front end side. The pair of sandwiching pieces can be elastically deformed, and the thread is latched by sandwiching the thread introduced through the thread guide portion by an elastic force.
In this embodiment, the support member side thread locking portions 4a to 4c are provided at the front and rear. This is because the yarns 2a to 2c are locked by the front support member side yarn locking portions 4a to 4c, but are also locked by the rear support member side yarn locking portions 4a to 4c, although not particularly limited. .

  Furthermore, in this embodiment, when the yarn support member 4 is lowered against the urging force of the coil spring 44 on the lowermost column portion 41, a scale for the user to confirm the lowering amount (operation amount). 45 is formed. For example, two scales 45 are formed on the upper and lower sides. For example, when the lower scale 45 coincides with the upper edge (indicator) of the base body 10, the end of rotation is indicated, and when the upper scale 45 coincides with the upper edge of the base body 10, the end of revolution is indicated. Alternatively, for example, when the lower scale 45 matches the upper edge of the base 10, the infant misanga is completed, and when the upper scale 45 matches the upper edge of the base 10, the adult misanga is completed. Also good. If it does in this way, the twisted yarn of predetermined length can be created easily and reliably.

  As mentioned above, although embodiment of this invention was described, it cannot be overemphasized that this invention is not limited to this embodiment, and can be variously deformed in the range which does not deviate from the summary.

  For example, in the above-described embodiment, the yarn support member 4 is formed by nesting a plurality of column portions, but may be formed by one hook member that is elastically bent. Also in this case, for example, if a scale is provided next to each other and the bending amount (operation amount) of the flange member is read, a twisted yarn having a predetermined length can be easily and reliably produced.

  In the above embodiment, the yarn is twisted by rotating the knob 5a. However, the yarn may be twisted by a motor. In this case, a motor capable of forward and reverse rotation is used as the motor.
