Description

  The present invention relates to a method of repeatedly stopping and re-rotating a circular rotating body having a central axis that rotates by twisting a power rubber string.

Toys that move using rubber strings have been developed for a long time (see, for example, Patent Document 1), but few toys have a function of repeatedly stopping and re-operation. However, for example, a marble ball rolling toy requires such a function. In this toy, when a marble is placed at the starting point of the uppermost ramp, the marble rolls down from the top due to the inclination, and the marble moves to the next ramp at a different level until the end of the lower ramp is reached. Rolls down. The rolled marbles are lifted manually to the starting point each time and rolling on the ramp is repeated. By introducing a rotating belt having a function of repeatedly stopping and re-starting the operation on the conventional rolling road toy, a new toy is born in which the marble rolling of the marble is repeated without using human hands.

Japanese Utility Model Publication No. 05-058193

As shown in the side view of FIG. 1, a rotating belt 3a structure is introduced into a conventional rolling toy rolling on a rotating body 4a and a lower pulley 4b. Due to the introduction of the rotating belt 3a structure, the marbles 1 released to the starting point of the uppermost ramp 2a roll from the uppermost ramp through the middle ramp 2b to the end of the lowermost ramp 2c and stop the rotation. The belt 3a is secured to fall on the tray 3b. The secured marble 1 is transported to the apex of the rotating body 4a by the actuated rotating belt 3a, discharged to the starting point of the uppermost ramp 2a, and simultaneously stops the rotating belt 3a. By the above process, the rolling of the marble 1 is realized. The function of stopping and restarting like the rotating belt 3a depends on the function of the rotating body 4a. An object of the present invention is to propose a rotation control method for controlling stop and re-rotation of the rotating body 4a which is driven by twisting of a power rubber string.

In order to stop and stop the rotating body 4a that is rotating, a stopping force R that can stop the rotational force W of the rotating body 4a is required. In order to re-rotate the rotating body 4a once stopped, a releasing force V for releasing the stopping force R is required. The rotational force W ranges from large to small depending on the toy. Usually, the large rotational force W is small and the small rotational force W is small and the small rotational force W is small. Although the rotating body 4a is stopped and re-rotated by the release force V, it is necessary to stop and re-rotate the rotating body 4a with a small rotational force R and a small releasing force V. There are also toys.

The present invention relates to a method for controlling the rotation of the rotating body 4a that can meet the above-described requirements for the rotational force W of the rotating body 4a. The control method will be described.

FIG. 2 shows a linear stop type rotation control method using the protruding bar 5 protruding outward from the outer peripheral surface of the rotating body 4a and the blocking bar 6a installed in a straight line. 2a to 2d are sectional views of the center position of the rotating body 4a for explaining the stopping and re-rotation of the rotating body 4a.

In the linear stop type rotation control method, the center portion of the stop rod 6a is supported by a hinge 6b, and is attached to the hinge 6b so as to be pulled in the rotating body 4a side, that is, inside the stop rod 6a in the rotating direction of the rotor 4a. A rubber string 6ca is attached, and a stopper 6d is installed on the attachment rubber string 6ca side so that the stop bar 6a and the protruding bar 5 are in a straight line. The stop rod 6a is attracted to and attached to the stopper 6d by the attachment rubber string 6ca, and cannot move in the rotation direction of the rotating body 4a. Since the attachment rubber string 6ca has a role of attracting the stop rod 6a to the stopper 6d, a large tensile string is not required and a thin rubber string is used. Regardless of the magnitude of the rotational force W of the rotating body 4a, the protruding bar 5 that abuts against the stop bar 6a is reliably stopped by the stopper 6d. The hinge 6b does not necessarily have to be provided at the central portion of the stop rod 6a, but is centered in the description for comparison with other control devices.

FIG. 2a shows a situation where the stop rod 6a is attracted by the attachment rubber string 6ca and is attached to and stopped by the stopper 6d. FIG. 2b shows a state in which the protruding rod 5 having the rotational force W that has been rotated contacts the stop rod 6a having the stop force R and is stopped by the stopper 6d, and the rotation of the rotating body 4a is stopped. The restraining force R is generated by the reaction force of the stopper 6d.

In FIG. 2c, an upward release force V is applied perpendicularly to the outer end operation portion of the restraining rod 6a, and the inner end abutting portion of the restraining rod 6a is moved downward by the hinge structure of the hinge 6a, so that the protruding rod 5 is moved. A situation is shown in which the rotating body 4a is once rotated in the direction opposite to the rotating direction and separated from the stop rod 6a. In order to rotate the protrusion bar 5 in the direction opposite to the rotation direction of the rotating body 4a by the release force V, a release force V equal to or greater than the restraining force R that stops the rotation force W must be applied to the protrusion bar 5. Therefore, a large release force V is required at the outer end portion operation portion of the stop rod 6a. FIG. 2d is a situation diagram in which the protruding bar 5 starts rotating in the rotation direction at the moment when the contact portion between the stop bar 6a and the protruding bar 5 is separated. When the release force V is removed almost simultaneously with the start of rotation, the stop rod 6a is attracted to the stopper 6d by the tensile force of the attachment rubber string 6ca and returns to the state shown in FIG. 2a. Can be stopped

FIG. 3 shows a linearly controlled rotation control method using the protruding bar 5 protruding outward from the outer peripheral surface of the rotating body 4a and the blocking bar 6a installed in a straight line. 3a to 3c are sectional views of the center position of the rotating body 4a for explaining the stopping and re-rotation of the rotating body 4a.

In the linear stop type rotation control method, the center portion of the stop rod 6a is supported by the hinge 6b, and the stop rubber cord 6cb is attached to the inside of the stop rod 6a so as to be pulled in the direction opposite to the rotation direction of the rotating body 4a. A stopper 6d is installed on the side of the restraining rubber cord 6cb so that the restraining bar 6a and the protruding bar 5 are in a straight line. The stop rod 6a does not fall below a predetermined position by the stopper 6d. The arrangement positions of the restraining rubber cord 6cb and the stopper 6d are symmetrical with respect to the restraining rod 6a in the attaching rubber cord 6ca and the stopper 6d in the linear stop type rotation control method.

FIG. 3a shows a situation where the restraining rod 6a is attracted by the tensile force of the restraining rubber cord 6cb and is attached to the stopper 6d. The original role of the restraining rubber cord 6cb For restraining, the rubber cord 6cb for restraining having a larger tensile force is necessary as the rotational force W of the rotating body 4a is larger, and a rubber cord having a large diameter corresponding to the rubber cord is used. FIG. 3b shows a situation in which the protruding rod 5 having the rotational force W of the rotating body 4a is restrained by the restraining force R of the restraining rod 6a, and the rotation of the rotating body 4a is stopped. The restraining force R of the restraining rod 6a is generated by the tensile force of the restraining rubber cord 6cb. When the projection bar 5 comes into contact with the stop rod 6a, the impact rubber string 6cb is slightly stretched by the impact, and the stop rod 6a is once moved in the slightly rotating direction and then stopped.

In FIG. 3c, a downward release force V is applied perpendicularly to the outer end portion operation portion of the restraining rod 6a, and the inner end abutting portion of the restraining rod 6a is moved upward by the hinge structure of the hinge 6a so as to be separated from the protruding rod 5. The rotating body 4a starts rotating at the same time as the abutting part is separated. If the release force V is removed immediately after the rotation of the rotating body 4a, the restraining rod 6a is pulled by the tensile force of the restraining rubber cord 6cb and returned to the position of the stopper 6d shown in FIG. 3a. After the rotation of the rotating body 4a, the rotation is stopped by the stop rod 6a. The release force V is based on the release force V of the linear stop type rotation control method in which the contact portion is temporarily rotated in the direction opposite to the rotation direction in order to rotate the inner tip contact portion of the stop rod 6a in the same direction as the rotation direction. Get smaller.

FIG. 4 is an explanatory view showing a non-linear restrained rotation control method in which the restraining bar 6a has an angle θ with respect to the protruding bar 5 projecting outward from the outer peripheral surface of the rotating body 4a. 4a to 4c are cross-sectional views of the center position of the rotating body 4a for explaining the stopping and re-rotation of the rotating body 4a.

The mechanism of the non-linear rotation control method is basically the same as that of the linear stop type rotation control method, but the attachment position and angle of the stop rod 6a are different. That is, unlike the linear stop type control method, the stop bar 6a and the protruding bar 5 are not linear, but an angle θ is provided between them, and the hinge 6b of the stop bar 6a is provided below the center of the rotating body 4a. It has been.

FIG. 4a shows a situation where the restraining rod 6a is attracted by the restraining rubber cord 6cb and is fixedly attached to the stopper 6d. FIG. 4B is a situation diagram in which the protruding rod 5 having the rotational force W of the rotating rotating body 4a is stopped by the stopping force R of the stopping rod 6a and the rotation of the rotating body 4a is stopped. If the stopping force R is R = W cos θ and θ is set to 45 degrees, the stopping force R becomes about 70% of the rotational force W and can be made smaller than the linear stop type rotation control method. The restraining force R is generated by the tensile force of the restraining rubber cord 6cb that pulls the restraining rod 6a in the direction opposite to the rotation direction of the rotating body 4a.

In FIG. 4c, a downward release force V is applied perpendicularly to the outer end operation portion of the restraining rod 6a, and the inner end abutting portion of the restraining rod 6a is moved upward by the hinge structure of the hinge 6a. It is the separated situation figure, and the rotary body 4a starts rotating simultaneously with the contact part separating. The release force V is smaller than that in the case of the linear stop type rotation control method, similarly to the stop force R. When the release force V is removed immediately after the rotation of the rotating body 4a, the restraining rod 6a is pulled by the restraining rubber cord 6cb and returned to the position of the stopper 6d shown in FIG. 4a. After the rotation of the rotating body 4a, the rotation is stopped by the stop rod 6a.

By providing an angle θ between the protruding rod 5 and the stop rod 6a, the stopping force R required to stop the protruding rod 5 and the release force V for releasing the stopping force R can be reduced. On the other hand, the moving distance L (see L in FIG. 5b) of the outer end portion operating portion of the stop rod 6a necessary for applying the release force V increases.

FIG. 5 is an explanatory view showing a rotation control method using a T-shaped stop body having an angle θ between the protruding bar 5 and the stop bar 6a as in FIG. In this T-type restraining body rotation control method, a vertical member 6e is vertically provided at the center of the restraining rod 6a, and a lower end portion of the vertical member 6e is fixed by a hinge 6b. Since the hinge position of the stop rod 6a is set to be lower than that of the non-linear type in FIG. 4, when the stop of the protruding rod 5 by the stop rod 6a is released, the inner tip contact portion of the stop rod 6a moves upward. It has the feature that it moves not only in the horizontal direction. 5a to 5c are cross-sectional views of the center position of the rotating body 4a for explaining stopping and re-rotation of the rotating body 4a.

FIG. 5a shows a situation in which the restraining rod 6a is attracted by the restraining rubber cord 6cb and is fixedly attached to the stopper 6d. FIG. 5b shows a state in which the protruding rod 5 having the rotational force W of the rotating body 4a is stopped, and the stopping force R of the stopping bar 6a is stopped by R = W cos θ, and the rotation of the rotating body 4a is stopped. The restraining force R is generated by the tensile force of the restraining rubber cord 6cb that pulls the restraining rod 6a in the direction opposite to the rotation direction of the rotating body 4a.

FIG. 5c applies a downward release force V perpendicularly to the outer end operation portion of the stop rod 6a, and the hinge structure of the hinge 6a of the T-type stop body allows the inner end abutting portion of the stop rod 6a only in the upward direction. FIG. 2 shows a situation in which the rotary body 4a is moved largely in the lateral direction and separated from the protruding bar 5, and the rotating body 4a starts rotating at the same time as the contact portion is released. When the release force V is removed immediately after the rotation of the rotating body 4a, the restraining rod 6a is attracted by the restraining rubber cord 6cb and returned to the position of the stopper 6d shown in FIG. 4a. After the rotation of the rotating body 4a, the rotation is stopped by the stop rod 6a. The release force V is smaller than that of the linear stop type rotation control method or the linear stop type rotation control method.

The stopping force R required to stop the protruding rod 5 and the releasing force V for releasing the stopping force are small as in the non-linear rotation control method. The difference from the non-linear rotation control method is that when the release force V is applied, the movement distance L (see L in FIG. 5c) of the outer end operation portion of the stop rod 6a is remarkably short. That is, the T-type stopping body rotation control method enables the control of the rotating body 4a with a small stopping force R and a small movement L.

Among the various rotation control methods described above, the release force V for releasing the restraining force R necessary to stop the rotating body 4a is the maximum in the case of the linear stop type rotation control method, and the next is the linear stop type rotation. It is a control method. In these methods, since the release force V for releasing is large, when releasing the stop of the rotation of the rotating body 4a, the outer end operation portion of the stop rod 6a is moved upward or downward by a human hand. The operation by human power is usually performed such that the hand is released immediately (the stop rod 6a returns to the original position). On the other hand, among the rotation control methods, the non-linear rotation control method and the T-type restraining body rotation control method are methods that can reduce the restraining force R and the release force V that releases it. For this reason, this method is usually used when the rotating body 4a is stopped and re-rotated using other small force regardless of human power.

In the four types of rotation control methods, the attachment positions of the stopper 6d, the attachment rubber string 6ca, and the restraining rubber string 6cb have been described with reference to FIGS. 2 to 5, but these attachment positions have functions. If it is the same, it is not limited to FIG. 2 thru | or FIG. Taking the attachment position of FIG. 2 as an example, the four examples shown in FIGS. 6A, 6B, 6C, and 6D show the attachment of the stopper 6d and the attachment rubber string 6ca to the stop rod 6a. Although the position is different, it has the same function. That is, the rotational force W of the rotating body is stopped by the stopper 6d, and the stop rod 6a is attracted to the stopper 6d by the attachment rubber string 6ca to be attached and stopped. You can select from 4 examples in consideration of the shape of the toy and the required functions. The same applies to FIGS. 3 to 5.

In the above description, since one protrusion bar 5 is attached to the side surface of the rotating body 4a, the rotating body 4a stops after one rotation. However, the protrusion bar 5 is positioned at the relative position of the side surface of the rotating body 4a. When two are attached, the rotating body 4a stops every half rotation. Further, the rotational force W at the tip of the protruding bar 5 decreases as the protruding bar 5 becomes longer. If the outside of the stop rod 6a is lengthened, the release force V for releasing the stop state becomes smaller. In actual toys, the number of the protruding rods 5 and the lengths of the protruding rods 5 and the stop rods 6a are determined in consideration of these factors.

The rotation control method of the present invention which can repeat the operation of stopping the rotation of the rotating body and re-rotating it at intervals gives a new possibility to the toy which uses the twist of the rubber string as a rotational force. Yes, it can be expected that a more interesting and interesting toy will be provided by adopting the rotation control method of the present invention.

  Embodiment 1 will be described with reference to FIGS. The first embodiment is an example of a toy rolling up toy rolling a marble 11 incorporating a linear stop type rotation control method. 7 is a plan view, FIG. 8 is a side view, and FIG. 9 is a cross-sectional view of the center position of the rotating body 14a.

Along the right and left right edges of the wooden base 100, three pairs of right edge vertical members 17 a that are paired with right and left are vertically fixed to the base 100. The three pairs of right edge vertical members 17a form a second and a third from the first on the farthest side of the base 100 toward the front. A bearing member 18a is fixed to the lower part of the right edge vertical member 17a forming the first pair, and a bearing member 18b is fixed to the upper part. The bearing material 18a is fixed to the lower part of the second pair of right edge vertical members 17a at the same height as the bearing member 18a fixed to the lower portion of the first right edge vertical members 17a. The shaft of the rotating body 14a is supported by the two bearing members 18a with the ball seat 32 interposed therebetween. The bearing material 18b is fixed at the same height as the bearing material 18b fixed to the upper part of the first right edge vertical member 17a on the upper part of the right edge vertical member 17a forming the third pair, The two bearing members 18b support a single common shaft to which the upper pulley 14c for the rotating belt that is paired with the pulley 14b in the upper and lower portions is fixed.

Two pairs of left edge vertical members 17c, which are paired on the left and right, are fixed to the base 100 vertically on the left edge of the base 100. The left edge vertical member 17c forming the rear pair is on the same row as the second edge right member 17a, and the left edge vertical member 17c forming the front pair is the third pair. It is on the same line as the right edge vertical member 17a to be formed. A bearing member 18c is fixed to the lower portion of the two pairs of left edge vertical members 17c, and the shaft of the lower pulley 14d for the rotating belt that is paired in two upper and lower portions is supported.

A front side vertical member 17b that forms a pair of two right and left in front of the base 100 is on the same row as the paired right edge vertical member 17a and is fixed to the base 100 vertically. A bearing member 18d is fixed to a lower portion of the front vertical member 17b, and a rotary handle 19a is supported. The shafts of the rotary handle 19a and the rotary body 14a have the same height. Two single front side vertical members 17d on the same line as the front side vertical member 17b are used to support the U-shaped ramp 12b and the like.

The curved cover 12a is supported by the second and third right edge vertical members 17a and the U-shaped ramp 12b, and the U-shaped ramp 12b is in the middle between the front vertical member 17b and the near side. The circular cover 12c is supported by the side vertical member 17d, and is supported by the U-shaped ramp 12b, the front side vertical member 17d, and the left edge portion vertical member 17c.

A rotating belt 13a is hung on the upper pulley 14c and the lower pulley 14d for the rotating belt paired in the upper and lower portions, and the rotating belt 13a is rotated by the rotation of the upper pulley 14c. ing. Since the upper pulley 14c is fixed to the same axis as the pulley 14b, it rotates in the same manner as the pulley 14b. The pulley 14b is connected by the rotating body 14a and the pulley belt 20, and the rotation of the rotating body 14a is transmitted to the pulley 14b, and the upper pulley 14c for the rotating belt also rotates together. One end of the power rubber cord 19b is hung on the hook of the rotating body 14a, and the other end of the power rubber cord 19b is hung on the hook of the rotary handle 19a. When the rotary handle 19a is rotated in the clockwise direction, the power rubber cord 19b is twisted, and rotational energy is stored in the rotating body 14a in the stopped state. The rotary handle 19a can be turned clockwise to twist the power rubber strap 19b, but not turn in the opposite direction. When the stopped state of the rotating body 14a is released, the rotating body 14a starts rotating, and the rotation is transmitted to the pulley 14b and the upper pulley 14c by the pulley belt 20, and the rotating belt 13a starts rotating.

The distance between the upper pulley 14c and the lower pulley 14d for a pair of rotating belts in the upper and lower portions is equal to or less than the circumferential length of the rotating body 14a. When the rotating body 14a makes one rotation, the rotating belt The lowest point of 13a exceeds the top of the upper pulley 14c. Further, since the diameter of the pulley 14b is smaller than the diameter of the rotating body 14a, when the rotating body 14a rotates once, the pulley 14b and the upper pulley 14c rotate further. The rotating body 14a requires a large rotational force, and the power rubber string 19b that rotates the rotating body 14a becomes thick.

10 is an enlarged explanatory view of the rotation control unit, FIG. 10a is a side view, and FIG. 10b is a sectional view of the center position of the rotating body 14a. A protruding rod 15 is fixed to the side surface of the rotating body 14a rotating in the clockwise direction, and a stop rod 16a for stopping the protruding rod 15 is hinged by a hinge 16b fixed to the second right edge vertical member 17a. It is fixed. The restraining bar 16a is bent at 90 degrees at the hinge portion and extends to the outside of the rotating body 14a. A stopper 16d is fixed to the second right edge vertical member 17a, which is the same as the hinge 16b, on the rotating direction side of the rotating body 14a. One end of the attachment rubber cord 16c is fastened to the upper position of the hinge 16b of the restraining rod 16a, and the other end is fastened to the second right edge vertical member 17a opposite to the hinge 16b. The inside of the stop rod 16a is attracted to the stopper 16d by the tensile force of the attachment rubber string 16c and is attached and stopped.

The rotation control of the rotating body 14a is performed as follows. The protrusion rod 15 protruding from the outer periphery of the rotating body 14a is prevented from rotating by the stop rod 16a, and the rotation of the rotating body 14a is stopped. Since the rotational force is large, a large stopping force is required to stop the protruding rod 15, and therefore, a linear stop type rotation control method is adopted, and the protruding rod 15 is completely stopped by the stopper 16 d. In order to re-rotate the rotating body 14a, the outer end operation portion of the stop rod 16a bent at 90 degrees is pushed down by a human hand. When the outer end portion operating portion of the restraining rod 16a is pushed down, the inner tip contact portion once rotates the projecting rod 15 in the direction opposite to the original rotation direction of the rotating body 14a, but the tip of the projecting rod 15 and the restraining rod 16a. At the moment when the abutting part is separated, the rotating body 14a rotates in the original rotation direction. When the pushed hand is released, the stop rod 15a is pulled by the attachment rubber string 16c and returns to its original position. The rotating body 14a that has made one rotation is again stopped by the stop rod 15a. The rotation and stop of the rotating body 14a are transmitted to the upper pulley 14b by the pulley belt 20, and the rotating belt 13a also rotates and stops.

The marbles 11 secured in the tray 13b on the lower side of the rotating belt 13a are lifted up to the top of the pulley 14b by the rotating belt 13a that has started rotating simultaneously with the rotation of the rotating body 14a, and are ejected vigorously. Is done. The rotating belt 13a that has released the marbles 11 stops. The discharged marble 11 draws a circle in the sky, hits the curved cover 12a, and rolls down to the U-shaped ramp 12b below. The marble 11 descends once, rises again at that moment, jumps up, is released again into the sky, is received by the circular cover 12c, and rolls down. The marble 11 is secured to fall on the tray 13b of the rotating belt 13a that is slowly rolling and stopped.

After the marble 11 is secured on the tray 13b of the rotating belt 13a, when the end operating portion of the stop rod 16a is pushed down, the rotating belt 13a starts to rotate and the jump-up rolling of the marble 11 is reproduced. In the toy of the first embodiment, if the rotary handle 19a is turned 10 times, the marble jump-up ramp road can be realized 10 times.

A second embodiment will be described with reference to FIGS. Example 2 is an example of a marble rolling toy incorporating a T-type stopping body rotation control method. FIG. 11 is a plan view thereof, FIG. 12 is a side view thereof, and FIG. 13 is a sectional view of the center position of the rotating body 24a.

Four right vertical members 27a are fixed in a straight line along the right and left right edges of the wooden base 200. The four right vertical members 27a form second, third, and fourth from the first farthest side of the base 200 toward the front. The top portions of the first, second, and third three right vertical members 27 a are fixed by a width stop member 31 with a gap therebetween. The shaft of the pulley 24c is supported on the top of the first and second right vertical members 27a, and the shaft of the pulley 24b is supported on the bottom of the ball seat 32. The shaft of the rotating body 24a is supported on the top of the third and fourth right vertical members 27a with the ball seat 32 interposed therebetween.

The shaft of the rotary handle 29a is supported on the front right vertical member 27d in front of the base 200. The shafts of the rotary handle 29a and the pulley 24b have the same height. A left vertical member 27 c is fixed to the back side and the front side along the left edge of the base 200. The left vertical material 27c on the back side is on the same line as the third right vertical material 27a, and the left vertical material 27c on the front side is on the same line as the fourth right vertical material 27a. The shaft of the lower pulley 24d for the rotating belt is supported on the lower side of the two left vertical members 27c, and on the upper side of the two left vertical members 27c, a rod-shaped stopper of a T-shaped restraining body is provided. The tool 26d penetrates.

Three middle vertical members 27b are fixed in a straight line at the center of the base 200, forming the first, second, and third from the back to the front. The first middle vertical member 27b is in the same row as the third right vertical member 27a, and the third middle vertical member 27b is in the same row as the fourth right vertical member 27a. The uppermost ramp 22a is supported by the fourth right vertical member 27a, the third middle vertical member 27b, and the front right vertical member 27d, and the middle ramp 22b and the lowermost ramp 22c are the fourth right vertical. It is supported by a material 27a, a third middle vertical material 27b, and a left vertical material 27c in front. The hinge 26b of the T-type restraining body is supported by the first and second middle vertical members 27b. The various vertical members are fixed to the base 200 vertically.

A rotating belt 23a is wound around the lower pulley 24d and the rotating body 24a for the rotating belt. The rotating belt 23a is rotated by the rotation of the rotating body 24a. In Example 2, the distance between the lower pulley 24d for the rotating belt and the rotating body 24a and the diameter of the rotating body 24a are determined so that the rotating belt 23a becomes more than half a turn by one rotation of the rotating body 24a. Accordingly, the lowermost tray 23b of the rotating belt 23a passes over the top of the rotating body 24a by one rotation of the rotating body 24a.

One end of the power rubber cord 29c is hung on the hook of the rotating body 24a, and the other end of the power rubber cord 29c is hung on the hook of the pulley 24c. The pulley 24c and the pulley 24b are connected by a pulley belt 30, and the rotation of the pulley 24b is transmitted to the pulley 24c. One end of the power rubber cord 29b is hung on the hook of the pulley 24b, and the other end of the power rubber cord 29b is hung on the hook of the rotary handle 29a. When the rotary handle 29a is turned clockwise, the power rubber string 29b is twisted, the pulley 24b is rotated, the rotation is transmitted to the pulley 24c by the pulley belt 30, and the power rubber string 29c is twisted. The rotational force is stored in the rotating body 24a that is stopped by the stop rod 26a and is in a standby state. The rotary handle 29a rotates clockwise to twist the power rubber strap 29c, but does not rotate in the opposite direction.

  The method of rotating the rotating body 24a many times by the two power rubber strings 29b and 29c is based on Japanese Patent Application No. 2015-192432 “Rotary driving device for increasing the number of rotations of the rotating body by twisting the rubber string”. The number of rotations of the rotating body 24a can be increased. In the first embodiment, when the power rubber cord 29b and the power rubber cord 29c are sufficiently twisted, the rotating body 24a can be rotated about 20 times.

FIG. 14 is an enlarged explanatory view of the rotation control unit of the second embodiment, FIG. 14a is a plan view, and FIG. 14b is a cross-sectional view of the center position of the rotating body 24a. A control rod oblique path 22d is connected to the operation portion outside the control rod 26a of the T-type control body. A protruding rod 25 is fixed to one side surface of the rotating body 24a. The tip of the protrusion rod 25 is in contact with the inner tip contact portion of the stop rod 26a of the T-shaped stop body, so that the rotation of the protrusion rod 25 is stopped. One end of the restraining rubber cord 26c is fastened to the inside of the restraining rod, and the other end of the restraining rubber cord 26c is fastened to a horizontal member 26f fixed to the first middle vertical member 27b. A restraining rod ramp 22d connected to the outside of the restraining rod 26a by the tensile force of the restraining rubber cord 26c is brought into contact with and stopped by the stopper 26d.

If the tensile force of the restraining rubber cord 26c is too weak, the protruding rod 25 cannot be restrained. If it is too strong, the vertical releasing force V applied to the outer operation portion of the restraining rod 26a becomes too large, and the contact of the restraining rod 26a It becomes difficult to separate the contact portion and the tip of the protruding rod 25. For this reason, fine adjustment of the tensile force is further required after selection of the restraining rubber cord 26c. When a ring-shaped rubber cord is used as the restraining rubber cord 26c and the ring-shaped rubber cord is turned around the horizontal material 26f whose surface is roughened, the ring-shaped rubber cord is deformed by the rough surface effect of the horizontal material 26f. It can be held at any position. The pulling force of the ring-shaped rubber string increases as the position where the ring-shaped rubber string is fastened is increased. Therefore, by adjusting the position where the ring-shaped rubber string is fastened, it is possible to finely adjust the tensile force of the restraining rubber string. .

In the toy of Example 2, two marbles 21a and 21b are prepared. By placing the marble 21b on the tray 23b at the bottom of the rotating belt 23a and dropping another marble 21a on the starting point of the uppermost ramp 22a, the rolling of the marble starts (see ● 21a and ● 21b in FIG. 12). . The marbles 21a dropped to the starting point of the uppermost ramp 22a slowly roll down while meandering due to the inclination, move to the stop rod ramp 22d of the T-type stop, and reach the tip of the stop rod ramp 22d. Due to the dead weight of the marble 21a that has reached the tip, the tip of the blocking rod ramp 22d is lowered (refer to the blocking rod ramp 22d of the thin line in FIG. 12), the inner tip of the blocking rod 26a is raised, and it contacts the protruding rod 25 of the rotating body 24a. The contact portion is released, and the rotating body 24a starts to rotate and the rotating belt starts to rotate. The marble 21b secured on the tray 23b below the rotating belt 23a is carried to the top of the rotating body 24a and discharged toward the uppermost ramp 22a. After discharge, the rotating belt 23a stops.

On the other hand, the other marble 21a falls from the tip of the lowered stop rod ramp 22d to the middle ramp 22b, rolls on the lowest ramp 22c, and is secured to the tray 23b of the rotating belt 23a that is stopped. The discharged marble 21b passes through the starting point and slowly moves while meandering the uppermost ramp 22a. After the marble 21a is secured on the receiving tray 23b, the marble 21b reaches the tip of the blocking rod ramp 22d. When the marble 21b reaches the tip, the rotating belt 23a starts to rotate as described above, and the marble 21a is carried to the top of the rotating body 24a and released, and dropped to the starting point of the uppermost ramp 22a. In the meantime, the marbles 21b also roll to fit in the tray 23b below the rotating belt 23a. In this way, the state at the start of the rolling of the slope is reproduced, and the two marbles 21a and 21b can alternately roll repeatedly from top to bottom. In the toy of the second embodiment, approximately 20 rounds of rolling of the marble are realized by turning the rotary handle 29a 50 times.
