Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a pin ball device for a pachinko machine that is small and easy to assemble and is used in an electric pachinko machine.

(Prior art) Conventional ball devices for pachinko machines are, for example,
As shown in Publication No. 58-101686, a force adjustment disk is provided on the side of the bullet mallet, and the tip of the bullet spring is wound around this disk, and the bullet handle and this disk are connected by wire. Usually, the force of the ball can be adjusted by tying the ball to the ball and rotating the disk by operating the handle, and the setting value of the tension of the ball spring can be changed using this disk. However, in such conventional devices, the ball mallet, the tension adjuster disc, and the ball handle must be mounted independently on the board, which requires a large space and is not easy to assemble. There were some shortcomings.

(Problems to be solved by the invention) The present invention was completed with the aim of solving the above-mentioned conventional problems and creating a ball device for pachinko machines that is small and easy to assemble without taking up much space. It is.

(Means for Solving the Problems) The present invention provides the following features:
A tension adjuster is installed, which consists of two clutch gears that normally mesh on the same axis and whose relative positions can be changed by sliding in the axial direction, and a gear that meshes with one of the clutch gears. While fixing the center shaft of the handle, a coiled bullet handle is tightly wound around a drum coaxial with the bullet hammer, and the wire connected to the end of the handle is fixed to the other clutch gear. It is characterized by being directly wrapped and fixed.

(Embodiment) Next, the present invention will be described in detail with reference to the illustrated embodiment. 1 is a base plate, 2 is a bullet pin pivoted on the base plate 1, and 3 is a base plate 1 on the side of the pin ball pin 2. A tension adjuster 4 is attached to the center axis of the ball handle 5. Tension adjuster 3 is provided coaxially with 2
It consists of two clutch gears 6 and 7 and a gear 8 that meshes with one of the clutch gears 7.The clutch gear 6 is integrally formed with a shaft 10 having a knob 9 at its tip as shown in the figure. Shaft 1 on the back of knob 9
A coil spring 11 is provided around 0. Since fine teeth 12 are formed on the opposing surfaces of these clutch gears 6 and 7, the two clutch gears 6 and 7 are normally held against each other at the teeth 12 by the elastic force of the coil spring 11. Although they are in mesh with each other, by pushing the knob 9 against the force of the coil spring 11 and sliding and rotating the clutch gear 6 in the axial direction, the relative position of the two can be changed. The gear 8 meshing with one of the clutch gears 7 has a fan shape that spreads out at a center angle of about 170°, as shown in FIG.
A fan-shaped stopper 13 extending from the side at a central angle of about 90° is provided adjacent to the gear 8, so that the gear 8 can only rotate within an angular range of about 100°. The central shaft 4 of the ball handle 5 is directly fixed to the gear 8 of the integrated tension regulator 3, and the clutch gears 6 and 7 can be rotated via the gear 8 by operating the handle. . A wire 16 is connected to the end of a bullet spring 15 which is tightly wound around a drum 14 provided coaxially with the bullet mallet 2 and one end of which is fixed. It is directly wrapped and fixed around the outer periphery of the clutch gear 6. Note that 17 is a cam roller that engages with an electric cam (not shown) to swing the ball mallet 2;
18 and 19 are rubber stoppers.

(Function) The device configured as described above rotates the gear 8 to an appropriate position by manually operating the ball handle 5 while swinging the ball mallet 2 using an electric cam (not shown). The two clutch gears 6 and 7, which are normally in mesh with each other, are rotated simultaneously to adjust the amount of tension on the wire 16 fixed to the clutch gear 6, thereby tightly wrapping the wire 16 around the drum 14 and tightening one end of the wire. The tension of the fixed coiled ball spring 15 is adjusted to adjust the flight position of the ball. Since this coiled ball spring 15 is tightly wound around the drum 14, surging does not occur.

If the pachinko parlor wants to change the tension setting, push in the knob 9 to slide the clutch gear 6 in the axial direction from the clutch gear 7, and then rotate the knob 9 to move the clutch gear 6 and clutch gear 7. By changing the relative position with respect to the ball handle 5, the tension of the ball spring 15 can be freely changed by changing the tension amount of the wire 16 while keeping the ball handle 5 at a constant position. In this way, in the present invention, the tension of the ball spring 15 can be freely adjusted, and since the whole is compactly integrated, it can be easily assembled on the board 1 in a cassette type, and the whole is compact. Therefore, the substrate 1 can be made smaller.

(Effects of the invention) As is clear from the above description, the present invention fixes a gear to the center shaft of the ball handle, meshes the clutch gear of the tension adjuster with the gear, and engages the clutch gear of the tension adjuster. Since the gear and the bullet hammer are directly connected by a wire and a spring for the bullet which is tightly wound around the drum and fixed, it is small, takes up little space, and can be assembled very easily. However, since the ball spring is tightly wound around the drum, it is possible to absorb the surging of the spring, eliminating the unpleasant vibrations caused by the ball hitting the drum. The ball force can be adjusted freely. Therefore, the present invention has extremely great practical value as a ball device for pachinko machines that solves the problems of the conventional machines.
