Abstract

PURPOSE:To keep on movable wings tilting semipermanently, by moving the rotating body to the reverse direction by the oscillation of a lever equipped on the case frame of the movable wings to make the normal movement of the rotating body caused by the contact of balls and the reverse movement thereof caused by the oscillation of such lever repeated alternately. CONSTITUTION:On the rotating body 11, an interlocking piece 21 is formed and inside the case frame 8, a cam 23 provided with a protrusion 22 interlocking with the interlocking piece 21 and a lever 16 which oscillates because of balls entering from the ball inlet 9 of the case frame 8 are formed. When the balls are guided to the ball inlet 9 while the movable wings 3 are open, tilting twice from the standing up position, the balls get on the ball receiving face 18 of the lever 16, causing the lever 16 to rotate upward due to the weight of such balls. Then the interlocking material 26 of the cam 23 is moved upward by the pushing up section 27, which makes the cam 23 rotate downward. Because of such movements, the protrusion 22 of the cam 23 contacts with the interlocking piece 21 of the rotating body 11 and causes the rotating body to rotate to the reverse direction. Even when the balls enter between the movable wings 3 and cause the rotating body 11 to rotate to the normal direction under such situation, the movable wings 3 tilt again and open without standing up.

Ball contact piece 14a
And the rotor 11 is rotated forward by 120 degrees as shown by the chain line in FIG. 4, and flows out of the ball passage 10 rearward from the ball inlet 2.

On the other hand, the movable blades 3 and 3 are the same as those of the rotor 11.
The forward rotation of 20 degrees causes the engagement walls 15 and 15 to move rearward to release the engagement with the protrusions 5 and 5 of the movable wing pieces 3 and 3.
As shown by the chain line in Fig. 2, it tilts outward by its own weight and opens. After that, similarly, each time the ball passes between the movable wing pieces 3 and 3, the rotating body 11 rotates forward by 120 degrees, and the movable wing pieces 3 and 3 stand up once and tilt twice. Then do it.

Further, when the movable wing pieces 3, 3 are erected as shown by the solid line in FIG. 5, when the ball received from the ball introduction port 9 of the box frame 8 is received by the ball receiving surface 18 of the lever piece 16, The lever piece 16 rotates upward (clockwise) as shown by the chain line in FIG. 5 due to the weight of the ball, and the feed claw 20 of the lever piece 16 contacts the ball contact piece 14b of the rotating body 11 to rotate the rotating body 11 by 120 degrees. Rotate forward. As a result, the movable wing pieces 3 and 3 which are erected tilt. The operation described so far is known.

However, as shown by the solid line in FIG. 6, when the movable wing pieces 3, 3 are tilted twice from the upright position and are open, when the sphere is guided to the sphere introduction port 9, the sphere moves to the lever piece 16. The lever piece 16 rides on the ball receiving surface 18 and rotates upward (clockwise) as shown by the chain line in the figure. Then, the push-up portion 27 moves the engaging member 26 of the cam member 23 upward to rotate the cam member 23 downward (counterclockwise direction) as shown by a chain line in the figure. As a result, the projection 22 of the cam member 23 comes into contact with and engages with the engaging piece 21 of the rotating body 11 to reverse the rotating body 11 by 120 degrees as shown by the chain line in FIG. Therefore, in this state, even if a sphere is inserted between the movable wing pieces 3 and 3 to rotate the rotating body 11 forward by 120 degrees, the rotating body 11 only returns to the position shown by the solid line in FIG. Tilts and opens again without standing. In this way, by repeating the normal rotation and the reverse rotation of the rotating body 11 alternately, the movable blade pieces 3 can be kept tilted semipermanently.

In the above embodiment, the two-fold safe ball receiver has been described, but the present invention is not limited to this, and any safe-ball receiver having at least two opens can be applied. It is possible. Moreover, it goes without saying that the number of engaging pieces can be arbitrarily selected.
