Description

The present invention provides a cantilever structure in which one side of an elastic plate, such as a hard plastic or a spring material, having appropriate strength and rigidity and having flexibility, is fixed horizontally to form a free-standing structure of the elastic plate. A downward force is applied to the contact portion at the end to deflect the elastic plate downward, and then the elastic plate rebounds simultaneously with the removal of the downward force of the contact portion. The present invention relates to a device for flipping up a sphere, which flips up a sphere placed on the elastic plate in the vicinity of a part.

The method of bending the elastic body and popping out the object by the return reaction force is, from the familiar thing of bending the index finger with the thumb in the flipping play, releasing the thumb and flipping the index finger and playing the repelling, the spring material with the elastic body It is not unusual to see it widely in pachinko toys (see Patent Document 1). However, unlike the above, the present invention relates to a device for repeatedly bouncing one object upward. The present invention relates to a device that uses a sphere as an object, and repeatedly performs a process in which a sphere that has jumped upward falls, rolls, returns on the elastic plate, and again jumps the returned sphere upward. Such devices have not been widely generalized so far.

JP-A-8-66512

A single sphere placed on an elastic plate by using an elastic plate made of a hard plastic having moderate strength and rigidity and having flexibility, and by bending an elastic plate bent downward to rebound upward. It is an object of the present invention to develop a device for flipping a sphere that can repeatedly flip a ball upward, and to develop and commercialize a new toy using the device for flipping a sphere.

An elastic plate structure 2 constituting a main part of a device for flipping a sphere using an elastic plate will be described with reference to FIG.

1A is a plan view of the elastic plate structure 2, FIG. 1B is a side view thereof, and FIG. 1C is a cross-sectional view of the position of the slide fixing plate 4. A wide widening member 4a protruding outside the horizontal supporting member is fixed on a horizontal supporting member (hatched member in FIG. 1), and two upper and lower slide fixing plates 4 sandwiching the elastic plate 2a in a horizontal manner are formed by the widening member. The elastic plate 2a is fixed to the protruding portion 4a by tightening the clip 4b, and the elastic plate 2a has a cantilever structure. The length from the fixing position of the elastic plate 2a to the free end and the left and right positions are adjusted so that the sphere 1 can be efficiently ejected, and the slide fixing plate 4 is fixed by tightening the clip 4b. A free end of the elastic plate 2a is provided with a contact portion 2c for receiving a force acting downward, and a partition frame 2b close to the contact portion 2c for holding the sphere 1 so as not to protrude from the elastic plate 2a. Can be The contact portion 2c may have any structure as long as it can receive a downward force against which another member comes from above.

FIG. 2 (a) shows the state of the elastic plate 2a fixed horizontally by placing the sphere 1 between partition frames 2b of the elastic plate structure 2 (the portion surrounded by the dotted line in FIG. 2 (a)) by solid lines. A state in which a downward external force F is applied to the contact portion 2c at the free end of the plate 2a to bend the elastic plate 2a downward is indicated by a dashed line. FIG. 2B shows a state in which the external force F acting on the abutting portion 2c at the free end is removed from the elastic plate 2a in a state parabolically bent by a solid line. The situation where the elastic plate 2a bounces upward and the sphere 1 placed in the partition frame 2b of the elastic plate 2a is flipped into the air is indicated by a dashed line.

The external force F acting on the contact portion 2c at the free end of the elastic plate 2a shown in FIG. 2 is performed by the method described with reference to FIG.

  The device A for flipping up a sphere shown in FIG. 3 includes the elastic plate structure 2 and the driving rotator 6 described in FIG. The driving rotator 6 includes a driving shaft 5 a for rotating the driving rotator 6 and a projection 6 a provided on the outer periphery of the driving rotator 6. When the drive rotating body 6 is rotated by the rotation of the drive shaft 5a, the protrusion 6a abuts on the contact portion 2c of the elastic plate 2a from above (see the solid line in FIG. 3), and the elastic plate 2a is bent downward. When the projection 6 further rotates and the projection 6a comes off from the contact portion 2c (see a dashed line), the elastic plate 2a rebounds upward as described in FIG. The drive shaft 5a is connected to a rubber cord, and is rotated by the return of the twisted rubber cord.

  The projection 6a of the device A for flipping up the sphere 1 shown in FIG. 3 comes into contact with the contact portion 2c of the elastic plate 2a every one rotation of the driving rotator 6. Normally, the return rotation speed of the rubber cord is high, and it is too fast for the ball 1 to fly off. Therefore, a deceleration treatment is performed to reduce the rotation speed. When the rotation speed of the rubber cord 6 is reduced, the projection 7a comes into contact with the elastic plate 2a 25 times, which is a half of the number of times the rubber cord is twisted, for 50 times of twisting of the rubber cord, and the sphere 1 is displaced. You can flip up 25 times. The number of times of lifting is a calculation for explaining the difference between the lifting devices B and C described below, and is slightly different from the actual.

  The device B for flipping a sphere shown in FIG. 4 includes the driving rotator 6 having the elastic plate structure 2 and one protrusion 6a described in FIG. 1, and the rotation of the driving rotator 6 described in FIG. (A portion surrounded by a dotted line in FIG. 4). The stop plate structure 8 is one to which "Patent No. 6105801" is applied. The stop plate structure 8 is provided near the outer periphery of the driving rotary body 6, and has a stop plate 8a and a rotation shaft 8b for rotatably fixing the stop plate 8a. The stop plate 8a includes a stop portion 8f on one side of the rotating shaft 8b and an operation portion 8e on the other side (see the arrow W). In addition, the restraining plate structure 8 is designed so that the rubber string 8c that pulls the operating portion 8e so that the abutting protrusion can be stopped, and the stopping portion 8f of the restraining plate 8a cannot rotate in the opposite direction to the rotation of the driving rotating body. 8d.

In the driving rotary body 6 shown in FIG. 4, the projection 6a of the driving rotary body 6 is stopped by contacting the stop portion 8f of the restraining plate 8a of the restraining plate structure 8 (see the solid line). When the operating portion 8e of the stopping plate structure 8 is pressed down by the pressing force W to rotate the driving rotating body 6, the stopping plate 8a is rotated in the same direction as the rotation of the driving rotating body 6, and the contact with the projection 6a is released. , The driving rotator 6 starts rotating (see the dashed line). The rotation of the driving rotator 6 causes the protrusion 6a to abut on the contact portion 2c of the elastic plate 2a from above (see the solid line of the elastic plate 2a), and the elastic plate 2a is once bent downward, but further rotation of the driving rotator 6 is performed. As a result, the protrusion 6a comes off the contact portion 2c (see the dashed line in the elastic plate 2a). When the projection 6a comes off, the elastic plate 2a rebounds upward as described in FIG. 2, and the sphere 1 on the elastic plate 2a is flipped upward. The driving rotator 6 that continues to rotate abuts the stop 8f of the stop plate 8a, and the rotation is stopped. When the player wants to flip the ball up, the driving rotator 6 is rotated by applying a pressing force W to the operation portion 8e of the stop plate 8a, and the sphere 1 can be flipped upward.

In the device B for ejecting a sphere shown in FIG. 4, the projection 6a comes into contact with the contact portion 2c of the elastic plate 2a for each rotation of the driving rotator 6. Therefore, for example, when the rubber cord is twisted 50 times, the driving rotating body 6 also rotates 50 times, and the projection 6a comes into contact with the elastic plate 2a 50 times, so that the sphere 1 can be flipped up 50 times.

  An apparatus C for flipping a sphere will be described with reference to FIGS. The device C has the elastic plate structure 2 described with reference to FIG. 1 and the two short-length protrusions 6a that cannot reach the contact portions 2c of the elastic plate structure 2 at 180-degree intervals. It comprises a body 6, a free rotating body 7 described below, and a forked stopping plate structure 9 (a portion surrounded by a dotted line in FIG. 5) for stopping the driving rotating body 6.

  Rotating blades 10 protruding in the free rotation direction are fixed at right angles to the short protrusions 6a of the driving rotor 6. The rotary wing 10 is configured to bend freely in the rotation direction of the driving rotator 6 but not in the opposite direction.

The free rotating body 7 is fixed to a free rotating shaft 5b that can freely rotate the outer periphery of the drive shaft 5a. On the outer periphery, a long protrusion 7a longer than the protrusion 6a and reaching the contact portion 2c of the elastic plate structure 2 is provided. The weight 7b is fixed to the end of the long protrusion 7a.

As shown in the perspective view of FIG. 6, the forked stopping plate structure 9 is provided with a stopping stopping plate 9a disposed on the rear side in the rotation direction of the driving rotator 6 and at the front side in the rotation direction of the driving rotator 6 with an interval. And a rotation operating plate 9f arranged.

The stop-stop plate 9a is formed integrally with a lower rectangular main plate-shaped portion 9g and an upper end of the main plate-shaped portion 9g so as to extend upward toward the drive rotating body 6. 9h, and has a passage space 9i on the free rotating body 7 side at the upper end of the main body plate-shaped portion 9g. A rotation shaft 9b is fixed to the upper end side of the main body plate portion 9g of the stopping restraint plate 9a, and the main body plate portion 9h rotates in the opposite direction to the drive rotating body 6 at the lower end portion of the main body plate portion 9g. Is provided, and a stopper 9d is provided to abut the lower end of the main body plate 9g so that the main body plate 9g does not rotate too much.

The rotation operation plate 9f is arranged so as to correspond to the passage space 9i of the stop-stop plate 9a, and the upper end of the rotation operation plate 9f projects slightly above the upper end of the stop-stop plate 9a. The lower end of the rotation operating plate 9f is connected to the upper end of the main plate-shaped portion 9g on the side of the passage space 9i by a connecting member 9e.

  As shown in FIG. 7A, the variable wing 10 of the projection 6a is composed of two layers, a lower rubber material 10a and an upper hard material 10b, and the tip ends of the lower rubber material 10a and the upper hard material 10b are adhered to each other to form an adhesive portion 10c. No. The variable wing 10 is fixed parallel to the drive shaft 5a, and the lower rubber material 10a is fixed at right angles to the projection 6a. The variable wing 10 is on the rotation trajectory of the long projection 7a of the free rotating body 7 (see FIG. 7a), and the rotating long projection 7a comes into contact with the variable wing 10 (see FIG. 7b). (See FIG. 7c), so that the passage of the long protrusion 7a is not hindered. When the long protrusion 7a passes, the variable wing 10 returns to the original state (see FIG. 7a), but is not broken in the opposite direction by the upper hard material 10b.

As shown in FIG. 5, when one of the protrusions 6a of the rotating driving rotator 6 comes into contact with the stopping restraint plate 9a, the rotation of the driving rotator 6 is stopped (see FIG. 7A). Even when the driving rotary member 6 stops, the rotation of the free rotary member 7 continues, and the long projection 7a contacts the contact portion 2c of the elastic plate 2a, and further contacts the variable wing 10 of one of the stopped projections 6a. Also in contact (see FIG. 7b), it passes through the variable wing 10 bent in the traveling direction and abuts on the rotary operating plate 9f (see FIG. 7c).

Due to the contact of the long protrusion 7a with the rotation operation plate 9f, the pressing force by one protrusion 6a and the contact force by the long protrusion 7a are added to the forked stopping plate structure 9. This combined force causes the forked stopping plate structure 9 to rotate about the rotation shaft 9b in the same direction as the drive rotating body 6 (see a dashed line in FIG. 5 and FIG. 7d). As a result, the stop of one of the projections 6a is released, the rotation of the projection 6a starts, and the variable wing 10 (see FIG. 7A) which has returned to the original state pushes the long projection 7a, whose rotational force has dropped, from behind. Business begins.

When the one protrusion 6a and the long protrusion 7a engaged by the rotation of the driving rotator 6 reach the apex, the other projection 6a comes into contact with the stopping restraint plate 9a of the forked stopping plate structure 9 and stops. Is stopped, and the rotation of the one protrusion 6a that has reached the top is also stopped. However, the long protrusion 7a that has already been pushed up to the top has the property of falling downward due to the inertia of the weight 7b and the gravity, so that the free rotating body 7 Shifts to free rotation, the long protrusion 7a abuts against the contact portion 2c of the elastic plate 2a from above, deflects the elastic plate 2a, passes through the sphere 1, and jumps up the sphere 1 to rotate the plate 2 of the forked stop plate structure 9. Reaches 9f. The free rotation body 7 makes one rotation by half rotation of the driving rotation body 6. Therefore, for example, when the rubber cord is twisted 50 times, the free rotating body 7 can rotate 100 times twice, and the long projection 7a of the free rotating body 7 comes into contact with the elastic plate 2a 100 times, and the sphere 1 rotates 100 times. Can flip out upwards.

  To summarize the above three types of devices A, B, and C for flipping a sphere, the device A for flipping a sphere continuously flips the sphere every time the driving rotating body rotates, whereas the device A for flipping the sphere flips the sphere. The device B repeats stop and re-rotation each time the drive rotating body makes one revolution to jump up the sphere, and the device C that flips up the sphere causes the drive rotator to stop and re-rotate every half rotation to repeat the sphere. It has the characteristic of jumping up. As a result, if the number of twists of the rubber string for driving the driving rotary body 6 is set to 1 by the number of times the sphere is flipped by the flip-up device A which is reduced to one half, the flip-up device B becomes In the case of the device C for lifting up, it is quadrupled.

Utilizing the proposed sphere-lifting devices A, B, and C, a toy can be made that flips one sphere quickly or continuously at an arbitrary interval. In the embodiment using the apparatus for flipping a sphere of the present invention, a solid ball made of plastic is used as the sphere, and the torsional force of the rubber cord and the thin lead piece are superimposed as the driving force for flipping. It shows the one using the falling force due to gravity. It is expected to be used in various toys in the future.

First Embodiment A toy using the device A for flipping a sphere shown in FIG. 3 will be described with reference to FIG. FIG. 8A is a plan view of a toy for flipping a sphere, and FIG. 8B is a side view.

  The vertical members 26 fixed to the base 11 are fixed to a plurality of intersections of a vertical row and a horizontal row. The vertical rows, that is, the vertical rows are one vertical row, two vertical rows, three vertical rows, and four vertical rows from the left side of the base 11, and the height of the vertical member 26 is fixed although one vertical row is low and four vertical rows are high. The height slightly changes depending on the position where the position is set. The vertical members 26 in one row and two rows fixed to the base 11 are connected by horizontal support members 27a forming one row, two rows, four rows, and five rows from the upper side of the base 11. The height of the horizontal support members 27a is the same, and the pulley shaft 12 is supported by the horizontal support members 27a in one horizontal row and two horizontal rows, and the speed adjusting rotator 20 and the drive pulley are mounted on the pulley shaft 12. 19 is fixed.

The rotating body 20 for speed adjustment is obtained by applying “Japanese Patent No. 6030733”, and is used for the purpose of reducing the rotating speed of the driving pulley 19. The rotating handle 21 is supported by four horizontal rows and five horizontal rows of horizontal support members 27a. The rotation handle 21 can twist the rubber string 23 by rotation, but cannot rotate in the opposite direction. A rubber string 23 is hung on the hook of the pulley shaft 12 and the hook of the rotary handle 21. A fixed ball seat 14 is attached to the pulley shaft 12 and the rotary handle 21 so that the pulley shaft 12 and the rotary handle 21 are not pulled inward by the tension of the rubber string 23.

  The vertical members 26 in two vertical rows and three vertical rows are connected by horizontal support members 27b in one horizontal row, two horizontal rows, and three horizontal rows. The height of the horizontal support members 27b is the same, and the drive shaft 5a is supported by the horizontal support members 27b in one horizontal row, two horizontal rows, and three horizontal rows. Is fixed. A belt 22 is hung on the deceleration pulley 18 and the drive pulley 19. The rotation of the driving pulley 19 is transmitted to the deceleration pulley 18 by the belt 22, but the rotation speed of the driving pulley 19 is reduced because the deceleration pulley 18 has a larger diameter than the driving pulley 19. And transmitted to the speed reduction pulley 18.

  Three vertical members and four vertical columns of vertical members 26 are connected by two horizontal lines and three horizontal lines of horizontal members 27c, and the widening member 4a is fixed on the horizontal members 27c (corresponding to the hatched members in FIG. 1). The elastic plate structure 2 of FIG. 1 is fixed by the clip 4b (see FIG. 1).

  The spherical body 1 is flipped out by the elastic plate 2a in the vertical direction, but the variation is large, so that the fixed cylindrical frame 24 is provided so that the spherical body 1 does not protrude from the toy, and the height of the fixed cylindrical frame 24 can be adjusted. A height adjusting cylindrical frame 25 is put on the outside thereof.

  The sphere 1 is flipped upward as follows. The rotating body 20 for speed adjustment is temporarily fixed, and the rotating handle 21 is turned to twist the rubber string 23. The rotation handle 21 cannot be reversed. After the torsion is completed, the rotation of the driving pulley 19 is started to rotate when the rotating body for speed adjustment 20 is temporarily fixed, and the rotation of the driving pulley 19 is transmitted to the deceleration pulley 18 by the belt 22. Since the speed reduction pulley 18 has a larger diameter than the drive pulley 19, the rotation speed of the speed reduction pulley 18 is lower than the rotation speed of the drive pulley. As described above, the rotation speed of the driving rotary body 6 fixed to the same drive shaft 5 a as the deceleration pulley by the speed adjusting rotary body 20 and the deceleration pulley 18 is the first rotation speed due to the torsion of the rubber cord 23. It is greatly reduced compared to the rotation speed.

  When the driving rotator 6 rotates, the protrusion 6a fixed to the side surface of the driving rotator 6 comes into contact with the contact portion 2c of the elastic plate 2a from above, and as described with reference to FIG. The ball 1 placed in the partition frame 2b of the elastic plate 2a is ejected upward by bending upward and bouncing upward. The sphere 1 flipped out in the vertical direction collides with the upper surface of the height-adjusting cylindrical frame 25, falls and returns into the partition frame 2b on the elastic plate 2a (see the movement line of the sphere in FIG. 8B). The returned sphere 1 has the protrusion 6a of the driving rotator 6 that has made one rotation abuts against the contact portion 2c from above, and is repelled upward by bending and rebounding of the elastic plate 2a.

  Here, if the sphere 1 has not returned to the elastic plate 2a by one rotation of the driving rotator 6, the elastic plate 2a will rebound upward without the sphere 1. Such empty (empty) bouncing wastes the number of twists of the rubber cord 23. In order to avoid this, it is necessary to return the sphere 1 to the elastic plate 2a earlier than that based on one rotation of the driving rotator 6 already decelerated in two stages, so that the height of the height adjusting cylindrical frame 25 is reduced. Adjustments are made.

In the case of the present example, the rotation speed of the driving rotary body 6 is significantly reduced by the reduction processing of the rotation speed as compared with the number of twists of the rubber cord 23. For example, when the speed is reduced to half, when the rubber cord 23 is twisted 50 times, the number of rotations of the driving rotating body 6 is reduced to 25 times, and the number of times the ball 1 is flipped is also 25 times. The above rotation speed is not an actual rotation speed but a numerical value for comparison with other devices.

Second Embodiment A toy using the device B for flipping a sphere shown in FIG. 4 will be described with reference to FIGS. 1, 3, 9, and 11. FIG. FIG. 9A is a plan view of a toy for flipping a sphere, and FIG. 9B is a side view. FIG. 11 is a plan view of the projection prevention frame 28 of the sphere 1.

  Vertical members 26 are fixed to the base 11 at a plurality of intersections of the vertical rows and the horizontal rows. The rows in the vertical direction, that is, the vertical rows, form one vertical row, two vertical rows, three vertical rows, and four vertical rows from the left side of the base 11, and the height of the vertical members 26 varies depending on the fixed position. The vertical members 26 in one row and two rows fixed to the base 11 are connected by horizontal support members 27a forming one row, two rows, four rows, and five rows from the upper side of the base 11. The height of the horizontal support members 27a is the same, and the pulley shaft 12 for fixing the driving pulley 19 is supported by the horizontal support members 27a in one horizontal row and two horizontal rows. The speed adjusting rotator 20 used in the first embodiment is not used.

As in the first embodiment, the rotary handle 21 is supported by the horizontal support members 27a in four rows and five rows. A rubber string 23 is hung on the hook of the pulley shaft 12 and the hook of the rotary handle 21, and the fixed ball seat 14 is attached as in the first embodiment.

  The vertical members 26 in two rows and three columns are connected by horizontal support members 27b in one row, two rows, and three rows. The height of the horizontal support members 27b is the same, and the drive shaft 5a is supported by the horizontal support members 27b in one horizontal row, two horizontal rows, and three horizontal rows, and the deceleration pulley 18 and the drive rotary body 6 are mounted on the drive shaft 5a. Fixed. A belt 22 is hung on the deceleration pulley 18 and the drive pulley 19. The rotation of the driving pulley 19 is transmitted to the deceleration pulley 18 by the belt 22. Since the deceleration pulley 18 has the same diameter as the driving pulley 19, the deceleration effect is mainly due to the friction of the belt 22 and the like. Small and small.

  Vertical members 26 in three rows and four columns are connected by horizontal support members 27c in two horizontal rows and three horizontal rows, and widening members 4a are fixed to the horizontal support members 27c (corresponding to the hatched members in FIG. 1). The upper and lower slide fixing plates 4 sandwiching the elastic plate 2a horizontally are fixed to the widening member 4a by tightening the clips 4b (see FIG. 1).

A stop plate structure 8 (a portion surrounded by a dotted line in FIG. 9) for controlling the stop and re-rotation of the rotation of the driving rotator 6 is provided near the outer periphery of the driving rotator 6. The stopping plate structure 8 is obtained by applying “Patent No. 6105801” described in FIG.

  In the device B for flipping the sphere 1, the rubber string 8 c of the stop plate structure 8 can be selected so as to correspond to the magnitude of the rotational force of the driving rotator 6 due to the twist of the rubber string 23. Therefore, even when the torsional force of the rubber string 23 is large, the driving rotator 6 can be reliably stopped every rotation, and the rotation of the driving rotator 6 can be surely performed by strongly pressing down the operating portion 8e by hand. Can be started. For this reason, the force F for bending the elastic plate 2a is increased, and the sphere 1 can be popped out at most in the vertical direction.

  The sphere 1 is flipped upward as follows. As in the first embodiment, the drive pulley 19 is rotated by the torsion force of the rubber cord 23 twisted by the rotary handle 21, and the rotation is transmitted to the deceleration pulley 18 via the belt 22. The driving rotator 6 fixed to the same driving shaft 5a as the deceleration pulley 18 is rotated. The difference from the first embodiment is that the diameter of the deceleration pulley 18 is the same as that of the drive pulley 19. Therefore, the deceleration effect is mainly due to friction between the pulleys and is not large.

  When the operating portion 8e of the stop plate structure 8 is pressed down, the driving rotator 6 starts rotating, and the projection 6a fixed to the side surface of the driving rotator 6 comes into contact with the contact portion 2c of the elastic plate 2a from above. As described above, the sphere 1 placed on the elastic plate 2a is flipped upward by the upward rebound of the elastic plate 2a.

In the second embodiment, normally, the sphere 1 is flipped out at most in the vertical direction in order to increase the thickness of the rubber string 23 and increase the rotational force of the driving rotator 6. For this reason, the pop-out prevention frame 28 that can cover a wide range so that the sphere 1 that has been popped up at most does not protrude from the toy is provided. FIG. 11 is a plan view of the pop-out prevention frame 28. The pop-out prevention frame 28 is a funnel-shaped frame (see FIGS. 9 and 10) in which a small-diameter cylinder below the center and a large-diameter circumferential frame are connected at an angle. ). Further, a roof structure 28d (see a dotted line in FIG. 9) for suppressing the flying height of the sphere 1 may be provided above the pop-out prevention frame 28 so as not to protrude from the pop-out prevention frame 28.

The flipped-up sphere 1 falls and is returned on the elastic plate 2a while moving inside the pop-out prevention frame 28 (see the movement line of the sphere 1 in FIG. 9B). FIG. 11A is a plan view of the pop-out prevention frame 28, which is an example in which the curved partition frame 28b is formed in a spiral shape to extend the movement path in order to extend the time for the dropped sphere 1 to return to the elastic plate 2a. The fixed cylinder 28a is placed and fixed on the upper side of the curved partition frame 28b (see FIG. 11C), so that the sphere 1 jumps up more vertically. When the sphere 1 is returned to the partition frame 2b of the elastic plate 2a and then the operating portion 8e of the stopping plate structure 8 is pressed down, the sphere 1 is repelled upward by the upward rebound of the elastic plate 2a.

In the device B for flipping the sphere 1, for example, when the rubber cord 23 is twisted 50 times and the operating portion 8e is depressed 50 times, the number of rotations of the driving rotator 6 becomes 50 and the sphere 1 is flipped 50 times. Can be. Although it is a calculated value for comparison, it is larger than the number of times the device A flips up.

Embodiment 3 A toy using the device C for flipping a sphere shown in FIG. 5 will be described with reference to FIGS. 1 and 6, FIG. 5, FIG. 7, FIG. FIG. 10 (a) is a plan view of a toy for flipping a sphere, and FIG. 10 (b) is a side view.

  Vertical members 26 are fixed to the base 11 at a plurality of intersections of the vertical rows and the horizontal rows. The rows in the vertical direction, that is, the vertical rows, form one vertical row, two vertical rows, three vertical rows, and four vertical rows from the left side of the base 11, and the height of the vertical members 26 varies depending on the fixed position.

The vertical members 26 in one vertical line and two vertical lines are connected from the upper side of the base 11 by horizontal support members 27a forming one horizontal line, two horizontal lines, four horizontal lines, and five horizontal lines. The height of the horizontal support members 27a is the same, the pulley shaft 12 is supported by the horizontal support members 27a in one horizontal row and two horizontal rows, and the speed adjusting rotating body 20 (Japanese Patent No. 6030733 is applied) and the drive The tool 19 is fixed to the pulley shaft 12.

The speed adjusting rotating body 20 is used for the purpose of reducing the rotating speed of the drive pulley 18. The rotary handle 21 similar to that of the first embodiment is supported by the horizontal support members 27a in four rows and five rows. A rubber string 23 is hung on the hook of the rotary handle 21 which does not rotate in the reverse direction to the hook of the pulley shaft 12, and a fixed ball seat 14 is attached as in the first embodiment.

  The vertical members 26 in two rows and three columns are connected by horizontal support members 27b in one row, two rows, and three rows. The height of the horizontal support members 27b is the same, and the drive shaft 5a is supported by the horizontal support members 27a in one horizontal row, two horizontal rows, and three horizontal rows, and the deceleration pulley 18 and the drive rotating body 6, The free rotating body 7 is supported. The deceleration pulley 18 and the driving rotator 6 are fixed to the driving shaft 5a, and the free rotator 7 is fixed to a free rotating shaft 5b that can freely rotate around the outer periphery of the driving shaft 5a (see FIG. 5).

Two projections 6a are fixed to the outer periphery of the driving rotator 6 at an interval of 180 degrees, and each of the two projections 6a has a length that cannot reach the contact portion 2c of the elastic plate 2a. (See FIG. 7). A long projection 7a is fixed to the outer periphery of the free rotating body 7, and the long projection 7a is longer than the projection 6a of the driving rotating body 6 and has a length that reaches the contact portion 2c of the elastic plate 2a. (See FIG. 5).

A belt 22 is hung on the deceleration pulley 18 and the drive pulley 19. Drive pulley 1
9 is transmitted to the deceleration pulley 18 by the belt 22. Since the deceleration pulley 18 has the same diameter as the drive pulley 19, the deceleration effect is small mainly due to the friction of the belt.

  Vertical members 26 in three rows and four columns are connected by horizontal support members 27c in two horizontal rows and three horizontal rows having the same height, and a widening member 4a is fixed to the horizontal support members 27c, and the elastic plate 2a is horizontally moved. The upper and lower two slide fixing plates 4 sandwiched in the shape are fixed to the widening member 4a by clips 4b (see FIG. 1).

Below the driving rotator 6 and the free rotator 7, the forked stopping plate structure 9 described with reference to FIGS. 5 and 6 is installed (see a portion surrounded by a dotted line in FIG. 10B).

The flipped-up sphere 1 falls and returns inside the partition frame 2b of the elastic plate 2a while moving inside the jump-out prevention frame 28 (see the movement line of the sphere 1 in FIG. 10b). FIG. 11B is a plan view of the pop-out prevention frame 28, in which a linear straight partition frame 28c is provided so that the dropped sphere 1 returns to the elastic plate 2a quickly. The chain line in FIG. 10B is an example in which a roof structure 28d is provided.

  The sphere 1 is flipped upward as follows. As in the first and second embodiments, the driving pulley 19 is rotated by the torsion force of the rubber cord 23 twisted by the rotary handle 21, and the rotation is transmitted to the deceleration pulley 18 via the belt 22. Then, the driving rotating body 6 fixed to the same driving shaft 5a as the deceleration pulley 18 rotates.

As described with reference to FIG. 5, the driving rotator 6 that has started to rotate stops halfway by the bifurcated stopping plate structure 9 and stops. However, the long protrusion 7 a fixed to the free rotator 7 has the inertia of the weight 7 b and the gravity. As a result, free rotation is continued, and the ball 1 is flipped up by contacting the contact portion 2c of the elastic plate 2a from above. Therefore, in the device C for flipping the sphere, for example, when the rubber cord 23 is twisted 50 times, the driving rotator 6 rotates 50 times, but the free rotator 7 rotates 100 times and the sphere 1 jumps up 100 times. Although it is a calculated value for comparison, the number of times of bouncing is two times that of the device B, and four times that of device A.
