Description

  The present invention attaches a lower end of a yo-yo string to a rotating shaft, attaches it to a yo-yo string that rises while winding the yo-yo string around the rotating shaft, and descends while unwinding the yo-yo string from the rotating shaft. The present invention relates to a yo-yo string winding auxiliary device that can easily wind a string.

  A conventional yo-yo is composed of a pair of rotating bodies and a main shaft provided between the center portions of the pair of rotating bodies. This conventional yo-yo can be played as follows. Attach the lower part of the yo-yo string to the main shaft, form a loop to pass the middle finger on the upper part of the yo-yo string, wrap the yo-yo string around the main shaft, grip the pair of rotating bodies through the middle finger, and lower the pair of rotating bodies Drop as if thrown. The yo-yo descends while unraveling the yo-yo string, and the spindle rotates idly at the lowest position. When the yo-yo string is pulled lightly upward, the yo-yo string relaxes and rises while the yo-yo string is wound around the main shaft by the frictional resistance between the grooves provided on the side surfaces of the pair of rotating bodies and the yo-yo string (for example, Patent Document 1). .

  A recent yo-yo is composed of a pair of rotating bodies, a main shaft provided between the center portions of the pair of rotating bodies, and a rotating shaft provided rotatably on the main shaft. This is an improved version of the conventional yo-yo described above. Instead of attaching the yo-yo string directly to the main shaft, the yo-yo string is attached to the rotating shaft to improve the inertial force during idling and to make full use of various techniques. Yes. This recent yo-yo can be played as follows. Attach the lower part of the yo-yo string to the rotating shaft, form a loop to pass the middle finger on the upper part of the yo-yo string, wrap the yo-yo string around the rotating shaft, and then grip the pair of rotating bodies through the middle finger to the pair of rotating bodies Drop it like throwing it down. The yo-yo descends while unraveling the yo-yo string, and the rotating shaft runs idle at the lowest position and idles. When the yo-yo string is pulled lightly upward, the yo-yo string relaxes and rises while winding the yo-yo string around the rotating shaft by the frictional resistance between the grooves provided on the side surfaces of the pair of rotating bodies and the yo-yo string (for example, Patent Document 2). , 3).

  The yo-yo is in the idle state hanging at the lowest position, for example, after developing techniques such as `` dog walking '', `` sleeper '', `` blanco '', `` break away '', and pulling back to the hand Become. To move from the idle state to the wrapping state and pull it back to the hand, it can be performed by pulling the yoyo string lightly upward, and by the frictional resistance between the relaxed yoyo string and the groove provided on the side surface of the rotating body. A yo-yo string is wound around the rotating shaft or the main shaft. The technology for shifting from the idling state to the string winding state depends on whether or not a frictional resistance to the extent that it is wound between the relaxed string and the side surface of the rotating body can be generated, but the yo-yo string itself has a small resistance and is slippery. Therefore, it is extremely difficult for young people and beginners, and there is a problem that even a familiar person may not be able to do so. A yo-yo that cannot be pulled back to hand will gradually attenuate its inertial force and stop its rotation. For this reason, the yo-yo string has to be wound again, which is extremely troublesome. In addition, there is a problem that if you can't get it back to your hand no matter how many times you do, you will get bored and lose interest in yo-yo play itself.

  The present invention has been devised in view of the above problems, and can be attached to the yo-yo string without impairing the function of the yo-yo string, and can easily generate a frictional resistance to wind the yo-yo string around the side surface of the rotating body. Therefore, it is an object of the present invention to provide a yo-yo string wrapping auxiliary device that allows even a young person and a beginner to easily pull back yo-yo and enjoy yo-yo play without getting tired.

  In order to achieve the above object, the yo-yo string winding auxiliary device according to claim 1 of the present application is provided with a pair of rotating bodies, a main shaft provided between the center portions of the pair of rotating bodies, and a rotatable structure on the main shaft.

The yo-yo string is wound around the rotation shaft by contacting the head.

  In order to achieve the above object, the yo-yo string winding auxiliary device according to claim 2 of the present application is a yo-yo wound around a main shaft of a yo-yo comprising a pair of rotating bodies and a main shaft provided between the central portions of the pair of rotating bodies. A yoyo string winding auxiliary device attached to a string, wherein the apparatus main body is formed in a pipe shape having an inner diameter through which the yoyo string can be inserted and an outer diameter narrower than a gap between a pair of rotating bodies. In addition, it is possible to wind the yo-yo string around the main shaft by contacting the side surface of the rotating rotating body while being slidable with respect to the yo-yo string and being held at a predetermined position by frictional resistance. Features.

  In order to achieve the above object, the yo-yo string winding auxiliary device according to claim 3 of the present application is characterized in that the device main body is formed shorter than the radius of the rotating body.

And

  The yo-yo string winding auxiliary device according to the present invention is formed in a pipe shape having an inner diameter through which the yo-yo string can be inserted and an outer diameter narrower than the gap between the pair of rotating bodies, and has the elasticity to bend together with the yo-yo string. I have. The yo-yo winding auxiliary device is used by inserting a yo-yo string. After the yo-yo string is attached to the rotary shaft that can be rotated about the main shaft of the yo-yo, and the loop for passing the middle finger is formed on the upper part of the yo-yo string, the yo-yo string is wound around the rotary shaft. When the loop is gripped through the middle finger and dropped so as to throw it downward, the yo-yo string is unwound and lowered, and at the lowest position, the spindle rotates idly with respect to the rotation axis.

  The yo-yo wrapping auxiliary device according to the present invention can be fixed at any position of the yo-yo string because the yo-yo string is slidable with respect to the yo-yo string and can be held at a predetermined position by frictional resistance. If the yo-yo wrapping auxiliary device is positioned on the loop side of the yo-yo string, it will not come into contact with the rotating body of the yo-yo that is idling at the lowest position, so it will have any effect on the rise of the yo-yo winding. It is possible to provide ordinary yo-yo play that is difficult for young people and beginners. When the yo-yo winding auxiliary device is positioned on the pair of rotating bodies, the yo-yo string can be brought into contact with the side surface of the rotating body of the yo-yo that is idling at the lowermost position. Since the yo-yo goes up while relaxing and touching the side of the rotating body and winding the yo-yo string around the rotating shaft due to frictional resistance with the side of the rotating body, the yo-yo can be easily and reliably wound up. There is an effect that even a person or a beginner can provide easy yo-yo play.

For the next yo-yo, the lower part of the yo-yo string is pivotally attached to the main shaft of the yo-yo, and after forming a loop for passing the middle finger on the upper part of the yo-yo string, the yo-yo string is wrapped around the main axis and then gripped through the middle finger on the loop Then, if it is dropped like throwing it down, it descends while unwinding the yo-yo string, and the main shaft is idled and idles at the lowest position.

  If the yo-yo wrapping auxiliary device according to the present invention is placed on the loop side of the yo-yo string, it does not come into contact with the rotating body of the yo-yo that is idling at the lowest position, so it has no effect on the increase in the winding of the yo-yo. It is possible to provide normal yo-yo play that is difficult for young people and beginners. When the yo-yo winding auxiliary device is positioned on the pair of rotating bodies, the yo-yo string can be brought into contact with the side surface of the rotating body of the yo-yo that is idling at the lowermost position. Loosely contacts the side of the rotator, and the yo-yo rises while wrapping the yo-yo string around the spindle due to frictional resistance with the side of the rotator. Even for beginners, it is possible to provide easy yo-yo play.

  When the yo-yo winding assist device according to the present invention is formed to be shorter than the radius of the rotating body, it is hidden inside the pair of rotating bodies, so that the appearance is good and young people and beginners can easily play yo-yo. It has the effect of giving a strange feeling to what you are doing and surprised the viewer.

  An outline of one embodiment of the present invention will be described with reference to FIGS. The yo-yo string winding auxiliary device 3 includes a pair of rotating bodies 10 and 60, a main shaft 26 provided between the center portions of the pair of rotating bodies 10 and 60, and a rotating shaft provided rotatably on the main shaft 26. The yo-yo string 2 is wound around the rotating shaft 122 of the yo-yo 1 composed of the yo-yo 1. The apparatus body 4 is formed in a pipe shape having an inner diameter 4 a through which the yoyo string 2 can be inserted and an outer diameter 4 b narrower than the gap between the pair of rotating bodies 10, 60, and has the elasticity to bend together with the yoyo string 2. The yo-yo string 2 is slidable with respect to the yo-yo string 2 and can be held at a predetermined position by frictional resistance. To go.

  The yo-yo string winding auxiliary device 3 is used by inserting the yo-yo string 2. The yo-yo 1 attaches the lower part of the yo-yo string 2 to a rotating shaft 122 provided rotatably on the main shaft 26 of the yo-yo 1, and further forms a loop for passing a middle finger on the upper part of the yo-yo string 2, and then the yo-yo string 2 Is wrapped around the rotating shaft 122 and then held through the middle finger through the loop and dropped so as to be thrown downward, the yo-yo string 2 is unwound and the main shaft 26 is idled with respect to the rotating shaft 122 at the lowest position. Yo-Yo 1 runs idle.

  When the yo-yo strap 2 is inserted, the yo-yo wrapping auxiliary device 3 can be slid with respect to the yo-yo strap 2 and can be held at a predetermined position by frictional resistance, so that it can be fixed at any position of the yo-yo strap 2. If the yo-yo winding auxiliary device 3 is positioned on the loop side of the yo-yo string 2, it does not come into contact with the rotating bodies 10, 60 of the yo-yo 1 that is idling at the lowest position. It has no effect on the rise and becomes a normal yo-yo game that is difficult for young people and beginners. If the yo-yo winding auxiliary device 3 is positioned on the pair of rotating bodies 10 and 60 side, the yo-yo winding auxiliary device 3 can come into contact with the side surfaces 18 and 18 of the rotating bodies 10 and 60 of the yo-yo 1 that idles at the lowest position. When the yo-yo string 2 is pulled lightly upward, the yo-yo string 2 relaxes and comes into contact with the side surfaces 18 and 18 of the rotating bodies 10 and 60, and is brought into contact with the rotating shaft 122 by frictional resistance with the side surfaces 18 and 18 of the rotating bodies 10 and 60. Since the yo-yo 1 rises while the yo-yo string 2 is wound, the yo-yo 1 can be wound up easily and reliably, and the yo-yo play is easy even for young people and beginners. In this way, the yo-yo wrapping auxiliary device 3 can easily pull back the yo-yo 1 to a young person or a beginner, so that it is possible to enjoy yo-yo play without getting tired.

  The yo-yo winding auxiliary device 3 is attached to the yo-yo string 2 wound around the main shaft 26 of the yo-yo 1 including the pair of rotating bodies 10, 60 and the main shaft 26 provided between the center portions of the pair of rotating bodies 10, 60. It may be a configuration. The apparatus body 4 is formed in a pipe shape having an inner diameter 4 a through which the yoyo string 2 can be inserted and an outer diameter 4 b narrower than the gap between the pair of rotating bodies 10, 60, and has the elasticity to bend together with the yoyo string 2. The yo-yo string 2 is slidable with respect to the yo-yo string 2 and can be held at a predetermined position by frictional resistance, and the yo-yo string 2 is wound around the main shaft 26 by contacting the side surfaces 18 and 18 of the rotating bodies 10 and 60 during rotation. Go.

  In the yo-yo 1, the lower part of the yo-yo string 2 is rotatably attached to the main shaft 26 of the yo-yo 1, and a loop for passing a middle finger is formed on the upper part of the yo-yo string 2, and then the yo-yo string 2 is wound around the main shaft 26. Then, when the middle finger is passed through the loop and dropped so as to be thrown downward, the yo-yo string 2 is unwound and lowered, and the main shaft 26 idles and idles at the lowest position.

  If the yo-yo winding auxiliary device 3 is positioned on the loop side of the yo-yo string 2, it will not come into contact with the rotating bodies 10, 60 of the yo-yo 1 that is idling at the lowest position. This is a normal yo-yo game that is difficult for young people and beginners. If the yo-yo winding auxiliary device 3 is positioned on the pair of rotating bodies 10 and 60 side, the yo-yo winding auxiliary device 3 can come into contact with the side surfaces 18 and 18 of the rotating bodies 10 and 60 of the yo-yo 1 that is idling at the lowest position. When the string 2 is pulled lightly upward, the yo-yo string 2 relaxes and comes into contact with the side surfaces 18 and 18 of the rotating bodies 10 and 60, and the yoyo string is applied to the main shaft 26 by frictional resistance with the side surfaces 18 and 18 of the rotating bodies 10 and 60. Since the yo-yo 1 rises while winding 2, the winding up of the yo-yo 1 can be performed easily and reliably, and yo-yo play is easy even for young people and beginners.

  If the yo-yo winding auxiliary device 3 is formed shorter than the radius of the rotating bodies 10 and 60, the yo-yo winding auxiliary device 3 is hidden inside the pair of rotating bodies 10 and 60. It gives a strange feeling to the yo-yo playing and can surprise those who are watching. Further, in the yoyo string winding auxiliary device 3, as shown in FIG. 23 (b), the yoyo string 2 is not inserted when the expandable kerf 5 is linearly formed in the axial direction. Since the kerf 5 can be expanded and easily attached to and detached from the yo-yo string 2, even the yo-yo string 2 already attached to the yo-yo 1 can be easily attached.

  An outline of the electric yo-yo toy 1 will be described with reference to FIGS. The electric yo-yo toy 1 includes a pair of rotating bodies 10 and 60, a main shaft 26 provided between the center portions of the pair of rotating bodies 10 and 60, a pivot member provided on the main shaft 26, and a string member (yo-yo string) ) And a rotating shaft 122 around which 2 is wound. One rotary body 10 is provided with a drive motor 130, a gear mechanism 140 that transmits the rotation of the drive motor 130 to the rotary shaft 122, and a detection device 100 that detects the rotation of the rotary body 10.

Since the electric circuit is configured by being electrically connected by the conduction means 40 disposed on the main shaft 26 provided between the central portions of the two, the weight is distributed to the left and right rotating bodies 10 and 60 in a well-balanced manner. It can be reduced in weight and size, and is easy for young people and beginners to handle.

  In the electric yo-yo toy 1, the conduction means 40 includes an inner conduction shaft 41 provided on the inner side of the main shaft 26 and an outer conduction shaft 121 provided on the outer side of the main shaft 26. Therefore, the electric yo-yo toy 1 can constitute a safe electric circuit without the inner conduction shaft 41 and the outer conduction shaft 121 being in contact with each other.

  In the electric yo-yo toy 1, the outer conductive shaft 121 is formed in a cylindrical shape and is provided outside the main shaft 26, and a rotating shaft 122 is rotatably provided on the outer conductive shaft 121. Therefore, in the electric yo-yo toy 1, since the outer conductive shaft 121 is formed of a metal conductive material, the frictional resistance of the outer conductive shaft 121 is small, and smooth rotation of the rotating shaft 122 can be expected. Since the wear of the outer conductive shaft 121 is extremely small, the product life is long.

  The electric yo-yo toy 1 serves as a fixed shaft for fixing the pair of rotating bodies 10 and 60 by the inner conductive shaft 41 being inserted into the main shaft 26. Therefore, the electric yo-yo toy 1 does not need to be separately provided with a means for fixing and integrating the pair of rotating bodies 10 and 60, and can be manufactured inexpensively and compactly by reducing the number of parts. If the fixed shaft is constituted by a screw, one rotating body 10 and the other rotating body 60 can be easily disassembled, and the string can be easily entangled.

  The detection device 100 of the electric yo-yo toy 1 includes a first fixed contact plate 103, a second fixed contact plate 105 provided away from the first fixed contact plate 103, and the first fixed contact plate. 103 and a contact position that contacts the second fixed contact plate 105 substantially simultaneously, and a rolling contact that rolls to a non-contact position that does not contact at least one of the first fixed contact plate 103 and the second fixed contact plate 105. It consists of a child 101 and a magnet 115 that holds the rolling contact 101 in a non-contact position. In the electric yo-yo toy 1, the rolling contact element 101 rolls against the magnetic force of the magnet 115 due to the inertial force caused by the rotation of the rotating body 10, and the first fixed contact plate 103 and the second fixed contact plate. The motor 105 is configured to be brought into contact with 105 at substantially the same time and kept in contact with centrifugal force to drive the drive motor 130. Therefore, the electric yo-yo toy 1 can detect rotation reliably and quickly.

  In the electric yo-yo toy 1, the second fixed contact plate 105 is provided on both sides of the first fixed contact plate 103, and the rolling contact 101 is connected to the first fixed contact plate 103 and one second fixed contact plate. The drive motor 130 is driven in one direction when contacting the contact plate 105, and the drive motor 130 is driven in the other direction when contacting the first fixed contact plate 103 and the other second fixed contact plate 105. Yes. The electric yo-yo toy 1 can forcibly rotate the rotating body 10 by the drive motor 130 in the detected rotation direction of the rotating body 10, and can provide smooth play.

  The outline of another embodiment of the present invention will be described with reference to FIGS. The other detection device 150 of the electric yo-yo toy 1 is pivotally attached at one end and is provided apart from the swing contact 151 that can swing like a pendulum. The fixed contact plate 105 is in contact with the fixed contact plate 105 at the non-contact position with the fixed contact plate 105. The oscillating contact 151 oscillates against the magnetic force of the magnet 165 due to the inertial force generated by the rotation of the rotating body 10, contacts the fixed contact plate 105, continues to contact with the centrifugal force, and drives the drive motor 130. It is configured to drive. The electric yo-yo toy 1 can detect rotation reliably and quickly, and has a small number of parts and is inexpensive.

  In the electric yo-yo toy 1, the fixed contact plate 105 is provided on both sides of the swing contact 151, and when the swing contact 151 comes into contact with one fixed contact plate 105, the drive motor 130 is driven in one direction. When the other fixed contact plate 105 is touched, the drive motor 130 is configured to drive in the other direction. The electric yo-yo toy 1 can forcibly rotate the rotating body 10 by the drive motor 130 in the detected rotation direction of the rotating body 10, and can provide smooth play.

  In the electric yo-yo toy 1, a pair of detection devices 100, 100, 150, and 150 are provided to face one rotating body 10, and the drive motor 130 is detected when both the detection devices 100, 100, 150, and 150 detect rotation. It is configured to drive. In the electric yo-yo toy 1, the drive motor 130 is not driven only by detection by one of the detection devices 100 and 150, and therefore, the drive motor 130 can be prevented from being unexpectedly suddenly driven.

A ring-shaped conduction band 36 is attached to the main shaft 26 of the main shaft member 25, and a bent piece 37 of the ring-shaped conduction band 36 is inserted into the insertion hole 32 of the mounting plate 27 and fixed. When the conductive cylinder (outer conductive shaft) 121 is attached to the main shaft 26, one end of the conductive cylinder (outer conductive shaft) 121 comes into contact with the conduction band 36. A rotating shaft 122 is rotatably attached to a conductive cylinder (outer conducting shaft) 121. The driven gear 124 of the rotating shaft 122 is positioned on the mounting plate 27 side.

By combining, the main shaft member 25 and the motor mounting plate 50 are fixed to the rotating case 11.

  At the same time, the intermediate shaft 133 is rotatably attached to the bearing hole 56 of the motor mounting plate 50 and the bearing hole 19 formed in the rotating case 11. The spur gear 135 of the intermediate shaft 133 meshes with the drive gear 132, and the small gear 136 of the intermediate shaft 133 meshes with the driven gear 124 of the rotating shaft 122. After the pair of second fixed contact plates 105 and the guide member 102 are attached to predetermined positions of the rotating case 11, the outer cover 22 is fixed to the rotating case 11.

  The ring-shaped conduction band 36 is attached to the shaft cylinder portion 64 of the rotation case 61 of the other rotating body 60, and the bent piece 37 of the ring-shaped conduction band 36 is inserted into the insertion hole 72 of the rotation case 61 and fixed. A metal tongue piece 70 is fitted on the guide wall 69 of the rotating case 61. When a fixed shaft (inner conducting shaft) 41 attached to one rotating body 10 is inserted into a bearing hole 66 of the rotating case 61 and a nut 48 is screwed into a screw 45 of the fixed shaft (inner conducting shaft) 41, A rotating case 61 is fixed to the rotating body 10. The other end of the conductive cylinder (outer conductive shaft) 121 contacts the conduction band 36 of the rotating case 61. The metal tongue piece 70 contacts the screw 45 and the nut 48 of the fixed shaft (inner conductive shaft) 41. After the batteries 81 and 82 are mounted in the mounting recess 73 of the rotating case 61, the outer cover 90 is fixed to the rotating case 61. The batteries 81 and 82 can also be attached and detached by removing the lid 92 of the outer cover 90.

  The electric configuration of the electric yo-yo toy 1 is as follows. As shown in FIG. 15, the positive electrode contact terminals 85 of the batteries 81 and 82 are connected via the conduction band 36 of the other rotating body 60, the conductive cylinder (outer conduction shaft) 121, and the conduction band 36 of one rotating body 10. Are connected to one second fixed contact plate 105a. The negative electrode contact terminals 87 of the batteries 81 and 82 are connected to the other second fixed body via the metal tongue piece 70 of the other rotating body 60, the fixed shaft (inner conduction shaft) 41, and the metal tongue piece 30 of the one rotating body 10. It is connected to the contact plate 105b. One first fixed contact plate 103 a is connected to one terminal 130 a of the drive motor 130, and the other first fixed contact plate 103 b is connected to the other terminal 130 b of the drive motor 130. The conductive cylinder (outer conduction shaft) 121 and the fixed shaft (inner conduction shaft) 41 electrically connect the drive motor 130 and the detection device 100 of one rotating body 10 and the power sources 81 and 82 of the other rotating body 60. The conduction means 40 connected to the is constructed.

  The electric yo-yo toy 1 can be used as follows. As shown in FIG. 15, when the electric yo-yo toy 1 is not rotated, the metal ball 101 is moved away from the contact portion 120 of the second fixed contact plate 105 by the magnet 115 (non-contact position) P0. Since the current of the batteries 81 and 82 is not flowing to the drive motor 130, the drive motor 130 is in a non-driven state. As shown in FIGS. 21 and 22, the lower part of the string member (yoyo string) 2 is connected to the rotating shaft 122, and the string member (yoyo string) 2 is wound around the rotating shaft 122. When the electric yo-yo toy 1 is grasped through a loop formed in the upper part of the string member (yo-yo string) 2 through the middle finger and the electric yo-yo toy 1 is pushed downward, the pair of rotating bodies 10 and 60 are connected from the rotary shaft 122 to the string. The member (yoyo string) 2 is rotated and unwound while being unwound.

  When the rotating body 10 rotates, the drive motor 130 operates. That is, in FIG. 15, when the rotating body 10 rotates in the clockwise direction, the metal sphere 101 rolls counterclockwise against the magnetic force of the magnet 115 due to the inertial force, and the metal sphere 101a located above is one side. The first fixed contact plate 103a and one second fixed contact plate 105a move simultaneously to the contact position P1, and the lower metal ball 101b moves to the other first fixed contact plate 103b and the other fixed contact plate 103a. The second fixed contact plate 105b is moved to the contact position P1 that simultaneously contacts the second fixed contact plate 105b.

  The currents of the batteries 81 and 82 are the positive electrode contact terminal 85, the conduction band 36 of the other rotating body 60, the conductive cylinder (outer conduction shaft) 121, the conduction band 36 of one rotating body 10, and the second fixing of one. Contact plate 105a, metal sphere 101a, one first fixed contact plate 103a, terminal 130a of drive motor 130, terminal 130b of drive motor 130, the other first fixed contact plate 103b, metal sphere 101b, the other Negative electrode contact terminals 87 of the batteries 81 and 82 through the second fixed contact plate 105b, the metal tongue 30 of one rotating body 10, the fixed shaft (inner conduction shaft) 41, and the metal tongue 70 of the other rotating body 60. The drive shaft 131 of the drive motor 130 rotates counterclockwise.

  When the drive shaft 131 rotates counterclockwise, a drive gear 132 attached to the drive shaft 131, a spur gear 135 meshing with the drive gear 132, an intermediate shaft 133 that fixes the spur gear 135, and a small gear fixed to the intermediate shaft 133 136, the driven gear 124 meshing with the small gear 136 rotates, and the rotating shaft 122 tries to rotate counterclockwise. The rotating shaft 122 is connected and fixed to the lower part of the string member (yoyo string) 2 and thus does not rotate. Therefore, the rotating body 10 rotates at high speed clockwise around the rotating shaft 122.

  As long as the rotating body 10 is rotating, the metal sphere 101a is in contact with the first fixed contact plate 103a and the second fixed contact plate 105a at the same time, and the metal sphere 101b is Since the first fixed contact plate 103b and the other second fixed contact plate 105b are kept in contact with each other, high-speed rotation of the rotating body 10 is maintained. In the electric yo-yo toy 1, the pair of rotating bodies 10, 60 continue to rotate while being hung on the string member (yo-yo string) 2, so that various techniques can be developed.

  The electric yo-yo toy 1 is a string member when the string member (yo-yo string) 2 is slightly pulled upward in a state where the pair of rotating bodies 10 and 60 are hung on the string member (yo-yo string) 2 while continuing to rotate. The (yo-yo string) 2 comes loose and comes into contact with the resistance plates 18 and 18 fixed to the rotating bodies 10 and 60, and the rotating bodies 10 and 60 are connected to the string members by the frictional resistance between the string member (yo-yo string) 2 and the resistance plate 18. (Yoyo string) Ascend while wrapping 2. Since the pair of rotators 10 and 60 are gripped by the hand when ascending, the rotation of the pair of rotators 10 and 60 stops. When the rotating body 10 stops rotating, the centrifugal force does not act on the metal sphere 101, and the metal sphere 101 is separated from the contact portion 120 of the second fixed contact plate 105 by the magnetic force of the magnet 115. The driving of the drive motor 130 is stopped.

  Further, when the electric yo-yo toy 1 is pushed downward, the pair of rotating bodies 10, 60 are rotated counterclockwise while lowering the string member (yoyo string) 2 from the rotating shaft 122 and lowered. In FIG. 15, when the rotating body 10 rotates counterclockwise, the metal sphere 101 rolls clockwise against the magnetic force of the magnet 115 due to the inertial force, and the metal sphere 101a located above the The metal ball 101b is moved to a contact position P2 that simultaneously contacts one fixed contact plate 103a and the other second fixed contact plate 105b, and the lower metal ball 101b is connected to the other first fixed contact plate 103b and the second one. The fixed contact plate 105a is simultaneously moved to the contact position P2.

  The currents of the batteries 81 and 82 are the positive electrode contact terminal 85, the conduction band 36 of the other rotating body 60, the conductive cylinder (outer conduction shaft) 121, the conduction band 36 of one rotating body 10, and the second fixing of one. Contact plate 105a, metal sphere 101b, other first fixed contact plate 103b, terminal 130b of drive motor 130, terminal 130a of drive motor 130, one first fixed contact plate 103a, metal sphere 101a, the other Negative electrode contact terminals 87 of the batteries 81 and 82 through the second fixed contact plate 105b, the metal tongue 30 of one rotating body 10, the fixed shaft (inner conduction shaft) 41, and the metal tongue 70 of the other rotating body 60. The drive shaft 131 of the drive motor 130 rotates in the clockwise direction.

  When the drive shaft 131 rotates clockwise, the drive gear 132 attached to the drive shaft 131, the spur gear 135 meshing with the drive gear 132, the intermediate shaft 133 that fixes the spur gear 135, and the small gear 136 that is fixed to the intermediate shaft 133. The driven gear 124 that meshes with the small gear 136 rotates, and the rotating shaft 122 tries to rotate clockwise. Since the rotating shaft 122 is connected and fixed to the lower part of the string member (yoyo string) 2, the rotating shaft 122 does not rotate, and therefore the rotating body 10 rotates at high speed counterclockwise around the rotating shaft 122.

  As long as the rotating body 10 is rotating, the metal sphere 101a simultaneously contacts one first fixed contact plate 103a and the other second fixed contact plate 105b by the centrifugal force, and the metal sphere 101b Since the first fixed contact plate 103b and one second fixed contact plate 105a are kept in contact with each other, the high-speed rotation of the rotating body 10 is maintained. As described above, the electric yo-yo toy 1 can develop a wide variety of techniques because the pair of rotating bodies 10 and 60 continues to rotate while being hung on the string member (yo-yo string) 2.

  The electric yo-yo toy 1 is a string member when the string member (yo-yo string) 2 is slightly pulled upward in a state where the pair of rotating bodies 10 and 60 are hung on the string member (yo-yo string) 2 while continuing to rotate. The (yo-yo string) 2 comes loose and comes into contact with the resistance plates 18 and 18 fixed to the rotating bodies 10 and 60, and the rotating bodies 10 and 60 are connected to the string members by the frictional resistance between the string member (yo-yo string) 2 and the resistance plate 18. (Yoyo string) Ascend while wrapping 2. Since the pair of rotators 10 and 60 are gripped by the hand when ascending, the rotation of the pair of rotators 10 and 60 stops. When the rotating body 10 stops rotating, the centrifugal force does not act on the metal sphere 101, and the metal sphere 101 is separated from the contact portion 120 of the second fixed contact plate 105 by the magnetic force of the magnet 115. The driving of the drive motor 130 is stopped.

  The detection device 100 has been described with the rolling contact 101 using a metal sphere, but may be configured with a metal swing contact 151 as illustrated in FIGS. 16 to 19. The detection device 150 attached to one of the rotating bodies 10 is provided separately on both sides of the swing contact 151, a guide member 152 that pivotably mounts the swing contact 151, and the swing contact 151. And a fixed contact plate 105. As shown in FIG. 17, the guide member 152 includes an attachment plate 156, a shaft hole 157 formed on one side of the attachment plate 156, and a magnet attachment frame 160 formed on the other side of the attachment plate 156. A magnet 165 is attached to the magnet attachment frame 160.

  The guide member 152 is disposed so as to face the inner surface 12b side of the rotating case 11, and the shaft hole 157 is aligned with the screw hole 23a of the protrusion 23 formed facing the rotating case 11 shown in FIG. The threaded portion 154 of the support shaft 153 is inserted into the shaft hole 157 and screwed into the screw hole 23 a, thereby fixing the rotating case 11 facing the inner surface 12 b side. The guide member 152 is fixed to the guide shaft 153 so as not to rotate because the magnet mounting frame 160 fits into the guide recess 33 of the mounting plate 27 of the main shaft member 25 and the guide recess 57 of the motor mounting plate 50. . As shown in FIG. 18A, the swing contact 151 is swingably attached to the support shaft 153.

  Further, when the guide member 152 is fixed to the rotating case 11 by the support shaft 153, the contact piece 166 is fixed to the guide member 152 by the support shaft 153. As shown in FIG. 18B, the contact piece plate 166 includes a substantially semicircular substrate 167 and a bent piece 168 bent at a substantially right angle at one end of the substrate 167. The swing contact 151 is always in contact with the substrate 167 (contact piece 166) through the metal support shaft 153 and the screw portion 154, and the front portion 163 is stably held at the center by the magnet 165. Normally, the fixed contact plates 105 on both sides are not in contact with each other. The fixed contact plate 105 is as described above.

  The electric configuration of the electric yo-yo toy 1 is as follows. As shown in FIG. 19, the positive electrode contact terminals 85 of the batteries 81 and 82 are connected via the conduction band 36 of the other rotating body 60, the conductive cylinder (outer conduction shaft) 121, and the conduction band 36 of one rotating body 10. Are connected to one fixed contact plate 105a. The negative electrode contact terminals 87 of the batteries 81 and 82 are connected to the other fixed contact plate 105b through the metal tongue 70 of the other rotating body 60, the fixed shaft (inner conduction shaft) 41, and the metal tongue 30 of one rotating body 10. It is connected to the. One contact piece 166 a is connected to one terminal 130 a of the drive motor 130, and the other contact piece 166 b is connected to the other terminal 130 b of the drive motor 130.

  The electric yo-yo toy 1 can be used as follows. When the electric yo-yo toy 1 is not rotating, the swing contact 151 is held by the magnet 165 at a position away from the contact portion 120 of the fixed contact plate 105 (non-contact position). Since no current flows through the drive motor 130, the drive motor 130 is in a non-driven state. As shown in FIGS. 21 and 22, the lower part of the string member (yoyo string) 2 is connected and fixed to the rotating shaft 122, and the string member (yoyo string) 2 is wound around the rotating shaft 122. When the electric yo-yo toy 1 is grasped through a loop formed in the upper part of the string member (yo-yo string) 2 through the middle finger and the electric yo-yo toy 1 is pushed downward, the pair of rotating bodies 10 and 60 are connected from the rotary shaft 122 to the string. The member (yoyo string) 2 is rotated and unwound while being unwound.

  When the rotating body 10 rotates, the drive motor 130 operates. That is, in FIG. 19, when the rotating body 10 rotates in the clockwise direction, the swing contact 151 swings against the magnetic force of the magnet 165 due to the inertial force, and the swing contact 151a located above is fixed to one side. The swing contact 151b that is in contact with the contact plate 105a and is positioned below is in contact with the other fixed contact plate 105b.

  The currents of the batteries 81 and 82 are the positive electrode contact terminal 85, the conduction band 36 of the other rotating body 60, the conductive cylinder (outer conduction shaft) 121, the conduction band 36 of one rotating body 10, and the one fixed contact plate 105a. , Swing contact 151a, one contact piece 166a, terminal 130a of drive motor 130, terminal 130b of drive motor 130, other contact piece 166b, swing contact 151b, other fixed contact plate 105b, one rotating body 10 flows through the metal tongue 30, the fixed shaft (inner conduction shaft) 41, and the metal tongue 70 of the other rotating body 60 to the negative electrode contact terminal 87 of the batteries 81 and 82, and the drive shaft 131 of the drive motor 130 is counteracted. Rotate clockwise. When the drive shaft 131 rotates counterclockwise, the rotating body 10 rotates at a high speed clockwise around the rotation shaft 122 as described above.

  As long as the rotating body 10 is rotating, the swing contact 151a is in contact with one fixed contact plate 105a and the swing contact 151b is kept in contact with the other fixed contact plate 105b by centrifugal force. Ten high speed rotations are maintained. In the electric yo-yo toy 1, the pair of rotating bodies 10, 60 continue to rotate while being hung on the string member (yo-yo string) 2, so that various techniques can be developed.

  The electric yo-yo toy 1 is a string member when the string member (yo-yo string) 2 is slightly pulled upward in a state where the pair of rotating bodies 10 and 60 are hung on the string member (yo-yo string) 2 while continuing to rotate. The (yo-yo string) 2 comes loose and comes into contact with the resistance plates 18 and 18 fixed to the rotating bodies 10 and 60, and the rotating bodies 10 and 60 are connected to the string members by the frictional resistance between the string member (yo-yo string) 2 and the resistance plate 18. (Yoyo string) Ascend while wrapping 2. Since the pair of rotators 10 and 60 are gripped by the hand when ascending, the rotation of the pair of rotators 10 and 60 stops. When the rotating body 10 stops rotating, centrifugal force does not act on the swing contact 151, and the swing contact 151 is moved to a non-contact position away from the contact portion 120 of the fixed contact plate 105 by the magnetic force of the magnet 165. Returning, the drive of the drive motor 130 stops.

  Further, when the electric yo-yo toy 1 is pushed downward, the pair of rotating bodies 10, 60 are rotated counterclockwise while lowering the string member (yoyo string) 2 from the rotating shaft 122 and lowered. In FIG. 19, when the rotating body 10 rotates counterclockwise, the swing contact 151 swings against the magnetic force of the magnet 165 by the inertial force, and the swing contact 151a located above the other fixed contact. Simultaneously contacting the plate 105b, the swing contact 151b positioned below contacts one fixed contact plate 105a.

  The currents of the batteries 81 and 82 are the positive electrode contact terminal 85, the conduction band 36 of the other rotating body 60, the conductive cylinder (outer conduction shaft) 121, the conduction band 36 of one rotating body 10, and the one fixed contact plate 105a. , Swing contact 151b, the other contact piece 166b, terminal 130b of the drive motor 130, terminal 130a of the drive motor 130, one contact piece 166a, the swing contact 151a, the other fixed contact plate 105b, one rotating body 10 flows through the metal tongue piece 30, the fixed shaft (inner conduction shaft) 41, and the metal tongue piece 70 of the other rotating body 60 to the negative electrode contact terminal 87 of the batteries 81 and 82, and the drive shaft 131 of the drive motor 130 is watched. Rotate in the direction. When the drive shaft 131 rotates in the clockwise direction, the rotating body 10 rotates at a high speed in the counterclockwise direction around the rotation shaft 122 as described above.

  As long as the rotating body 10 is rotating, the swing contact 151a contacts the other fixed contact plate 105b and the swing contact 151b continues to contact the one fixed contact plate 105a by centrifugal force. Ten high speed rotations are maintained. As described above, the electric yo-yo toy 1 can develop a wide variety of techniques because the pair of rotating bodies 10 and 60 continues to rotate while being hung on the string member (yo-yo string) 2.

  The electric yo-yo toy 1 is a string member when the string member (yo-yo string) 2 is slightly pulled upward in a state where the pair of rotating bodies 10 and 60 are hung on the string member (yo-yo string) 2 while continuing to rotate. The (yo-yo string) 2 is loosened and comes into contact with the resistance plate 18 fixed to the rotating bodies 10 and 60, and the rotating bodies 10 and 60 are connected to the string member (yo-yo) by the frictional resistance between the string member (yo-yo string) 2 and the resistance plate 18. Ascend while winding the string 2). Since the pair of rotators 10 and 60 are gripped by the hand when ascending, the rotation of the pair of rotators 10 and 60 stops. When the rotating body 10 stops rotating, centrifugal force does not act on the swing contact 151, and the swing contact 151 is moved to a non-contact position away from the contact portion 120 of the fixed contact plate 105 by the magnetic force of the magnet 165. Returning, the drive of the drive motor 130 stops.

  In the above embodiment, the shape of the outer cover 22 of the rotating cases 10 and 60 protrudes outward from the shape of the drive motor 130, but the shape of the drive motor 130 is changed as shown in FIG. Thus, the protruding height of the outer cover 22 of the rotating cases 10 and 60 can be suppressed, and the rotating bodies 10 and 60 can be made lighter and more compact.

  As described above, the electric yo-yo toy 1 forcibly rotates the rotating bodies 10 and 60 by the drive motor 130 housed therein, so that even a young person or a beginner can take out a highly difficult technique. is there. Techniques with a high degree of difficulty include, for example, “walking dogs”, “sleepers”, “blanco”, “breakaway”, and the like. These highly difficult techniques are basically performed by rotating the rotating bodies 10 and 50 at a high speed while being hung on a string member (yoyo string). The high rotation of the rotating bodies 10 and 50 is described above. As described above, this can be achieved by the drive motor 130. The electric yo-yo toy 1 ends the technique by deploying the technique described above and then pulling it back to the hand.

  When the string member (yoyo string) 2 is slightly pulled upward in a tension state where the electric yo-yo toy 1 is suspended from the string member (yoyo string) 2 while the pair of rotating bodies 10 and 60 continues to rotate, The member (yoyo string) 2 is loosened and comes into contact with the resistance plates 18 and 18 fixed to the rotating bodies 10 and 60, and the rotating bodies 10 and 60 are stringed by the frictional resistance between the string member (yoyo string) 2 and the resistance plate 18. The member (yoyo string) rises while being wound. The operation of slightly pulling the string member (yoyo string) 2 upward to generate frictional resistance between the string member (yoyo string) 2 and the resistance plate 18 is extremely difficult for young people and beginners. That is, the string member (yoyo string) 2 used for the electric yo-yo toy 1 has a slippery property, and even if it slides on the resistance plate 18, it is difficult for friction resistance to occur.

  In the electric yo-yo toy 1 according to the present invention, as shown in FIGS. 21 to 23, a flexible pipe 3 is slidably attached to a string member (yo-yo string) 2 for handling the toy. The flexible pipe 3 is desirably formed of a material such as a soft synthetic resin, urethane, or rubber having elasticity, resilience, and flexibility. If it is such a material, even if the flexible pipe 3 is wound around the rotating shaft 122 together with the string member (yoyo string) 2 or stretched, the flexible pipe 3 moves following the string member (yoyo string) 2. Therefore, the operation of the electric yo-yo toy 1 is not adversely affected. The flexible pipe 3 is used by being put on a string member (yoyo string) 2 and is slidable with respect to the string member (yoyo string) 2, and is slid to a desired position and is slid by frictional resistance. It can be held at the moved position.

  21 (a) and 22 (a), the flexible pipe 3 is a pair of rotating bodies in a tension state in which the pair of rotating bodies 10 and 60 are hung on the string member (yoyo string) 2. When it is slid away from the position 10, 10, it does not come into contact with the resistance plates 18, 18 of the pair of rotating bodies 10, 60, so technology and habituation are required to pull the electric yo-yo toy 1 back to the hand. Become.

  21 (b) and 22 (b), the flexible pipe 3 is a pair of rotating bodies in a tension state in which the pair of rotating bodies 10 and 60 are hung on the string member (yoyo string) 2. When it is slid until it reaches a position near 10, 60, it can come into contact with the resistance plates 18, 18 of the pair of rotating bodies 10, 60, so that the electric yo-yo toy 1 can be easily pulled back to the hand. It becomes. Even in such a case, the flexible pipe 3 rotates without contacting the both rotating bodies 10 and 60 in a tension state in which the pair of rotating bodies 10 and 60 are hung on the string member (yoyo string) 2. It is located in the space between the body 10 and the rotating body 60.

  When the string member (yoyo string) 2 is slightly pulled upward in a tension state where the electric yo-yo toy 1 is suspended from the string member (yoyo string) 2 while the pair of rotating bodies 10 and 60 continues to rotate, The member (yoyo string) 2 is loosened and the flexible pipe 3 comes into contact with the resistance plates 18 and 18 of the rotating body 10 and / or the rotating body 60, and the rotating body 10 is caused by the frictional resistance between the flexible pipe 3 and the resistance plate 18. , 60 rises while winding the string member (yoyo string) 2. Since a large frictional resistance is generated between the flexible pipe 3 and the resistance plates 18, 18, even a young person or a beginner can easily pull it back. Needless to say, the flexible pipe 3 is not limited to an electric yo-yo toy and can be used for a string member (yo-yo string) of a normal yo-yo toy.

  As shown in FIG. 23A, the flexible pipe 3 has a pipe shape having an inner diameter 4 a through which the yoyo string 2 can be inserted and an outer diameter 4 b narrower than the gap between the pair of rotating bodies 10 and 60. It is formed, has elasticity to bend together with the yo-yo string 2, can slide with respect to the yo-yo string 2, and can be held at a predetermined position by frictional resistance. If the flexible pipe 3 is formed to be shorter than the radius of the rotating bodies 10 and 60, the flexible pipe 3 is hidden inside the pair of rotating bodies 10 and 60. It gives a strange feeling to the yo-yo playing and can surprise those who are watching it. Further, as shown in FIG. 23 (b), the flexible pipe 3 is cut without inserting the yo-yo string 2 when the expandable kerf 5 is linearly formed in the axial direction. Since the groove 5 can be expanded and easily removed from the yo-yo string 2, even the yo-yo string 2 already attached to the yo-yo 1 can be easily attached.

  The present invention can be used for a yo-yo string wound around a rotation shaft of a yo-yo.
