Description

  The present invention relates to a launch handle for a ball game machine that launches game balls into a game area of a game board.

  This type of launching handle includes a base body fixed below the front frame of the ball game machine and a rotating operation body supported rotatably at the front end of the base body. The body is urged to rotate to an initial position by an elastic member such as a torsion spring. The turning operation body is a movable side member that is manually operated by the player, and the launch intensity of the game ball is adjusted according to the turning angle of the turning operation body. In this case, since maintaining a posture in which the player grips the movable member with his / her palm for a long time is accompanied by considerable fatigue, a circular face cover connected and fixed to the base body is provided in front of the rotating operation body. A configuration in which the movable side member is rotated with the fingertip while the player holds the face cover with the palm is widely adopted. In addition, a plurality of finger holders project from the outer peripheral surface of the rotating operation body at predetermined intervals in the circumferential direction, and some of these finger holders protrude forward and face the outer peripheral surface of the face cover. is doing. Therefore, the player can press a plurality of fingertips (thumb, index finger, etc.) against each finger contact part with a wide contact area, and the restoring force per unit area acting on each finger from the elastic member is as much as possible. Therefore, the degree of fatigue experienced by each finger of the player can be greatly reduced.

By the way, in the launching handle configured as described above, the protruding portion of the finger holding portion that is the movable side member extends around the rear end portion of the face cover that is the fixed side member, and the outer peripheral surfaces of these face covers Since a gap is formed between the protrusion and the protruding portion of the finger holder, a fraudulent act is easily performed in which a foreign object such as a medal or a coin is sandwiched from the front to fix the rotating operation body. Therefore, conventionally, by launching a ball game machine that prevents the action of fixing the rotating operation body with a foreign object such as a coin by providing a finger holder so as not to protrude forward from the outer peripheral surface of the rotating operation body. A handle has been proposed (see, for example, Patent Document 1). In this case, since the protruding portion that faces the outer peripheral surface of the rear end of the face cover from the finger holder is omitted, there is no gap for inserting foreign objects such as coins around the rear end of the face cover. It is impossible to fix the rotating operation body by inserting a foreign object therebetween.

  In the launching handle of the ball game machine configured as described above, the finger contact part of the rotating operation body protrudes radially outward from the outer peripheral surface of the ring portion, so that the rotation operation with the rear outer peripheral surface of the face cover is performed. A foreign object such as a medal or coin cannot be inserted between the fingertip part of the body from the front, and a chamfered part formed on the rear end face of the face cover removes the foreign material hanging allowance. Since the amount of foreign matter inserted is defined by overlapping the cylindrical part protruding from the end face of the ring part with the inner peripheral surface of the rear end of the face cover, the rear end face of the face cover and the ring of the rotating operation body A foreign object such as a coin inserted from the side cannot be sandwiched between the two parts, and the act of fixing the rotating operation body by the foreign object sandwiching can be reliably prevented.

  In the above configuration, when an inclined stepped portion facing the chamfered portion of the face cover is formed on the end surface of the ring portion of the rotating operation body, foreign matter is caught from both the rear end surface of the face cover and the end surface of the ring portion. Since the allowance is removed, the function of preventing foreign matter from being caught can be further ensured.

  In the launch handle of the ball game machine according to the present invention, the finger holding part of the rotating operation body protrudes radially outward from the outer peripheral surface of the ring part. A foreign object such as a medal or coin cannot be sandwiched between the front and back, and a chamfered portion that is tapered from the outer peripheral side to the inner peripheral side is formed on the entire periphery of the rear end surface of the face cover. Since the cylindrical portion that extends forward from the end surface of the ring portion overlaps the inner peripheral surface of the rear end of the face cover, the rear end surface of the face cover and the ring portion of the rotating operation body The foreign object inserted from the side cannot be sandwiched between them, and the act of fixing the rotating operation body by the foreign object sandwiching can be reliably prevented.

A chamfered portion 9c that is tapered from the outer peripheral side toward the inner peripheral side is formed on the rear end surface over the entire periphery. The face cover 9 and the base body 8 are integrated with each other by inserting screws (not shown) from the back surface of the substrate portion 8b into the respective columns 8e and screwing them to the leg portions 9b. However, an annular space having a predetermined width is defined between the rear end face of the face cover 9 and the cylindrical jetty 8c of the base body 8, and the rotating operation body 10 is rotatably exposed from the annular space. ing.

  The rotating operation body 10 includes a ring portion 10a that protrudes outward from the annular space, a cylindrical portion 10b that protrudes forward from the front end surface of the ring portion 10a, and the like. The region is a base portion 10c. As shown in FIG. 8, the transmission body 14 is integrated with the rear end surface of the base portion 10 c using a fixing means such as a screw, and the transmission body 14 extends along the rotation center axis of the rotary operation body 10. And a shaft portion 14a protruding rearward. The distal end portion of the shaft portion 14 a is rotatably supported by the bearing tube portion 8 f of the base body 8, and the transmission body 14 functions as a rotating shaft that pivotally supports the rotating operation body 10 on the base body 8. A gear portion (not shown) is engraved on the outer peripheral surface of the shaft portion 14 a, and the gear portion meshes with the gear 13 described above, whereby the rotation operation body 10 is rotated via the transmission body 14 and the gear 13. Is transmitted to the rotary shaft of the rotary volume 12.

  Further, a rotation support shaft 10d is formed on the front end surface of the base portion 10c so as to protrude forward, and the rotation support shaft 10d and the shaft portion 14a of the transmission body 14 are arranged on the same line. The distal end portion of the rotation support shaft 10d is rotatably supported by the bearing portion 9a of the face cover 9, and the rotation operation body 10 is operated to rotate about the rotation support shaft 10d and the shaft portion 14a. A pair of arc-shaped holes 10e and spring receiving projections 10f are formed around the rotation support shaft 10d. The support protrusions 8d of the base body 8 and the respective pillars 8e are inserted through the arc-shaped holes 10e and the face cover 9 is inserted. Reached inside. As a result, the turning operation body 10 can be turned with respect to the base body 8 and the face cover 9 within a predetermined angle range. The turning range of the turning operation body 10 is the circumferential direction of the arc-shaped hole 10e. Are defined by the abutment of the two ends of the contact with the support 8e. As shown in FIG. 6, the rotating support shaft 10 d holds the winding portion 15 a of the torsion spring 15, and the pair of arms protruding from the winding portion 15 a rotate with the support protrusion 8 d of the base body 8. The operating body 10 is hooked on the spring receiving projection 10f. Thereby, the rotation operation body 10 is urged to rotate to the initial position in the rotation direction by the elastic force of the torsion spring 15 which is a return spring.

  The front end surface of the ring portion 10 a is orthogonal to the rotation center axis of the rotation operation body 10, and the rotation operation body 10 is between the front end surface of the ring portion 10 a and the rear end surface of the face cover 9. A gap S for smoothly rotating the face cover 9 with respect to the face cover 9 is secured. Here, since the chamfered portion 9c is formed on the rear end surface of the face cover 9 over the entire circumference, the gap S sandwiched between the chamfered portion 9c and the front end surface of the ring portion 10a is directed inward. The tapered cross section is substantially V-shaped. The inner peripheral surface of the rear end of the ring portion 10a overlaps with the outer peripheral surface of the cylindrical jetty 8c formed on the base body 8, and the outer peripheral surface of the rear end inner peripheral surface of the ring portion 10a and the cylindrical jetty 8c. A gap for smoothly rotating the rotating operation body 10 with respect to the base body 8 is secured between the surfaces.

This touch circuit determines whether or not the turning operation body 10 is in contact with the player. When the touch operation body 10 is in contact, it is possible to supply power to the motor of the launching device described above.

  In the ball and ball game machine configured as described above, when the player holds the face cover 9 with his palm and presses the fingertip against the finger holder 10g to rotate the rotation operation body 10, the rotation operation body 10 is The rotary support shaft 10d and the shaft portion 14a rotate around the rotation support shaft 10d and the rotation is transmitted to the rotary shaft of the rotary volume 12 via the transmission body 14 and the gear 13. As a result, since the amount of rotation of the rotation operation body 10 is detected from the rotary volume 12, the game ball stored in the tray 5 is rotated by controlling the motor of the launching device based on this detection signal. It is fired toward the game area of the game board 3 with a firing intensity corresponding to the amount of rotation of the body 10. Further, the torsion spring 15 is stored with the turning operation of the turning operation body 10, and when the turning operation force with respect to the turning operation body 10 is removed, the turning operation body 10 becomes the torsion spring. It automatically returns to the initial position by the resilience of 15.

  Here, in the firing handle 7 according to the present embodiment example, a chamfered portion 9c having a tapered shape from the outer peripheral side toward the inner peripheral side is formed on the rear end surface of the face cover 9 over the entire periphery. Therefore, as shown in FIG. 9, even if a foreign object 16 such as a medal or a coin is inserted into the gap S generated between the rear end surface of the face cover 9 and the front end surface of the ring portion 10a, the foreign object 16 is inserted into the face cover 9 The rear end face and the front end face of the ring portion 10a cannot be sandwiched. That is, even if a foreign object 16 such as a medal or a coin is inserted from the side into the gap S, the insertion amount of the foreign object 16 is regulated by the cylindrical portion 10f and the face cover 9 exposed in the gap S is exposed. Since the chamfered portion 9c removes the allowance for the foreign matter 16, the foreign matter 16 falls to the near side and falls out of the gap S as shown by a two-dot chain line in FIG. The body 10 cannot be fixed. Further, since the finger holding portion 10g of the rotating operation body 10 is set to have the same width as the ring portion 10a, the finger holding portion 10g and the outer peripheral surface of the rear end of the face cover 9 do not overlap, and the foreign matter 16 Cannot be sandwiched from the front between the finger holder 10g and the face cover 9. Since the turning operation body 10 cannot be fixed at the turning position by sandwiching the foreign object 16 in this way, the player must always turn the turning operation body 10 with his fingertip to play a game. It is possible to prevent an illegal act of playing in a state where the moving operation body 10 is fixed with the foreign object 16.
