Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handle speed control mechanism in a handle mechanism in a slot machine, and more particularly to a mechanism for preventing the handle from rotating beyond a certain level of rotation.

A slot machine has built-in mechanisms such as a handle mechanism, a handle lockout mechanism, and a reel mechanism, and when the handle is operated, the reels are rotated by a lantern in the reel mechanism.

However, according to the conventional example, when the handle is suddenly rotated, the timing in each mechanism is shifted, and the lighting operation of the lantern is not performed, leading to a situation where the reel does not rotate even though the handle is operated. This had the disadvantage that it not only weakened the interest of players, but also caused great damage to the business owners.

Furthermore, if the handle is allowed to rotate rapidly, the shock applied to each part becomes large, which also has the disadvantage of shortening the service life of the parts.

The present invention aims to correct the drawbacks of the above conventional example,
As shown in one embodiment of the handle speed control mechanism in a slot machine, a claw piece 3 is pivotally supported on a rotary plate 2 that rotates in conjunction with a handle 1 so as to be swingable in a centrifugal direction. A stopper 4 is attached to the rotating plate 2 to hold the claw piece 3 in a fixed position during normal rotation, while
A group of arc-shaped engagement teeth 6.6 parallel to the trajectory A drawn by the tip 5 of the claw piece 3 at a slight interval when the claw piece 3 is at the fixed position.
... is disposed, and when the handle 1 is rotated at a certain speed or higher, the claw pieces 3 are swung out in the centrifugal direction due to inertia and engage with the engagement teeth 6 of the stop member 7. It is characterized by being configured as follows.

FIGS. 2 and 3 show an embodiment of the present invention in a handle mechanism of a slot machine.A handle 1 and a rotating plate 2 are fixed to a handle shaft 9 that is mounted on a supporting frame 8. rotates integrally with the handle 1.

The rotary plate 2 has a fan-like shape, and has a rack 10 and a concave portion 11 formed on its upper edge, and an engaging protrusion 12 at its lower portion.

Further, the rotating plate 2 is urged in the return direction Q by a compression spring 13.

Reference numeral 14 denotes a bird-like locking pawl, and when the upper arm portion 15 thereof is rotated in the direction R in FIG.

Therefore, in order to unlock the handle 1 when starting the handle, it is necessary to rotate the lock pawl 14 in the direction S in FIG. 2.

Reference numeral 17 denotes a reverse rotation regulating pawl that engages with the rack 10 of the rotary plate 2, as shown in FIG. 3, to restrict the reverse rotation of the rotary plate 2.

When the rotating plate 2 is rotated by a predetermined angle in the operating direction P and the reverse rotation regulating pawl 17 sinks into the recessed part 11, the reverse rotation regulating function of the reverse rotation regulating pawl 17 is lost and the rotating plate 2 returns. Rotation is possible.

18 is a device for latching the rotating plate 2; a lock lever 19;
It is mainly composed of a hanging arm 20, a push-down member 21, and an operating lever 22.

This latching device 18 is such that when the rotating plate 2 is rotated a certain amount, the engaging protrusion 12 of the rotating plate 2 engages with the engaging step 23 of the lock lever 19, and the rotating plate 2 is returned to its original state. It is configured to prevent rotation.

To rotate the rotating plate 2 back, move the operating lever 22 to the second position.
Just press it in the direction S in the figure.

In the figure, 24 is a pressure spring, 25 is a tension spring, and 26 is a buffer member.

A pivot 27 embedded in the rotating plate 2 is located at the upper right corner of the rotating plate 2.
A stopper 4 is attached to the right side surface 28 of the rotary plate 2 for pivotally supporting the claw piece 3 in a swingable manner and for maintaining the claw piece 3 in a substantially horizontal state.

It is preferable that the mounting position of this stopper 4 is configured to be vertically adjustable.

When the rotating speed of the rotating plate 2 is below a certain value, the claw piece 3 maintains a state in contact with the stopper 4 due to its own weight, and no relative movement occurs between the claw piece 3 and the rotating plate 2.

The arc locus drawn by the tip of the claw piece 3 at this time is indicated by A in FIG.

A stopping member 7 is attached to the frame 8 and has a group of arcuate engagement teeth 6, 6, .

Thus, when the rotating speed of the rotating plate 2, and by extension the handle 1, is below a certain value, the claw piece 3 maintains a state in contact with the stopper 4, and the tip 5 of the claw piece 3 moves on the trajectory A. Because of the movement, the claw pieces 3 do not engage with the engagement teeth 6 of the restraining member 7, and the rotating plate 2 rotates smoothly in the direction S in FIG. 2.

On the other hand, when the rotating speed of the rotating plate 2, and by extension the handle 1, exceeds a certain value, the claw piece 3 is swung out in the centrifugal direction due to inertia, engages with the engagement tooth 6 of the stop member 7, and rotates. The plate 2, in turn, restrains the rotation of the handle 1 (shown by solid lines in Figure 3).

). Since the present invention has the above-described structure and operation, when the handle is rotated at a speed higher than a certain speed, the rotation of the handle is restrained, and the reel does not rotate even though the handle is operated, which is the conventional example. This has the effect of being able to correct the defects in , and also being able to alleviate the impact when operating the handle and improve the durability of the component parts.
