Description

[Detailed description of the invention] This invention relates to a winning device for a pachinko machine, and in particular, this invention is equipped with a pair of left and right rotating blades that open and close, and the blades are rotated alternately by the entry of a ball. This invention relates to an improvement of a prize-winning device, which is usually a tulip type or designated as a tulip, which can be opened and closed to change the entry conditions.

Tulip-type winning devices have already been widely put into practical use, but recently, in order to make the movement of the wing pieces that rotate as the winning device enters the prize even more impressive, and to improve the decorative effect, a technique has been added to the back of the wing pieces. It is equipped with an illumination lamp, and when a prize is won, the lamp is turned on to reveal the rotating state of the wing pieces, and may also display the prize.

Previously proposed devices with lamps installed a lamp behind the mounting board and illuminated the back side of the wing piece provided on the front of the mounting board by passing the light through a window cut into the mounting board. blinks relatively frequently and often burns out, requiring replacement.

However, as is known, the mounting board is attached to the front of the game board and is usually fixed by nailing, so it is extremely troublesome to replace the lamp installed behind it. , there was a problem that made it impossible to work easily.

Therefore, one way to solve this problem is to form a pocket section on the front of the mounting board separately from the mounting board, and secure it with a screw that is squeezed in from the front.When replacing the lamp, this screw can be used. A tulip-type winning device was proposed in which the pocket part was removed from the mounting board and the lamp could be replaced from the front.

However, the winning device according to this existing proposal requires removing and tightening screws when replacing the lamp, and requires tools such as a screwdriver for this purpose, so it is difficult to work and cannot be replaced easily. There was a problem that stores with a large number of machines could not perform sufficient maintenance and management.

This invention was devised in view of these points,
A main body in which a mounting board and a case part are integrated, and a pocket part for receiving a ball are formed separately, and the ball has a spring property that detachably engages with either the mounting board or the pocket part of the main body. The locking piece is provided with a locking part on the other side, and by engaging the two, the pocket part is removably assembled on the front surface of the mounting board, and when used, the lighting lamp provided on the main body side is cut out. To provide a prize-winning device which can easily be replaced by bending the locking piece to disengage the locking piece and removing the pocket part together with the rotary blade piece from the front surface of the mounting board to expose the lamp. It is in.

Hereinafter, this invention will be explained with reference to an illustrative embodiment, and its features will be further clarified.

FIG. 1 is a side view of the prize-winning device according to the present invention, FIG. 2 is a central vertical sectional side view when it is attached to a game board, and FIG. 3 is an exploded perspective view.

Reference numeral 1 in the drawings indicates a main body, and 2 indicates a pocket portion which is combined with the main body to form the winning device of the present invention.

The main body 1 consists of a mounting board 4 molded from synthetic resin, and a box-shaped case part 5 provided so as to protrude behind the mounting board. A control plate 7 is provided which is pivotably mounted on a shaft 6.

The control plate 7 has a swinging tip 7a that projects forward through an entry port 8 formed vertically in the mounting board, so as to face a rotary blade piece to be described later.

Reference numeral 9 indicates sockets 10 provided on both sides of the case portion 5.
This is a lamp for illumination that is attached to a mounting board 4 and protrudes from the front through an opening 11 formed in a mounting board 4.

On the other hand, the pocket part 2 is also molded from synthetic resin, and has a bottom plate 13 extending along the lower edge of the front decorative plate 12 and having a generally arcuate cross section. A locking piece 1 is provided with a locking pawl 14 at a tip portion which is partially cut off by a slit cut into the opening edge from the rear and projects rearward.
5 is set. Then, two parallel support shafts 16, 16 on the left and right are respectively erected from the back surface of the decorative plate 12 along the opening edge where both the locking pieces are provided, and the rotary blade pieces 17, 17 are pivoted on these. It's meant to be worn.

By providing the locking piece 15 integrally when molding the pocket portion with synthetic resin, the piece itself takes advantage of the springiness of the material and is able to bend freely. A protrusion 18 is provided on the outer surface so that it can be easily bent inward by pushing it in with a finger, and the locking pawl 14 at the tip can be retracted.

Reference numeral 19 denotes a through-hole-shaped locking portion formed in the mounting board 4 of the main body 1 in correspondence with the locking piece 15 described above.

This locking portion 19 is made large enough to allow the locking claw 14 at the tip of the locking piece to pass through, and the locking claw inserted from the front is passed through and is latched to the edge of the back side of the board using the spring properties of the piece. It's like this.

The rotating wing pieces 17 each pivotally attached to the support shaft 16 have a main portion shaped like a thick petal and are hollow and open to the rear, with a pivot at the base end of the petal. A fitting part 20 is provided, and the support shaft 1 is attached to the pivot fitting part.
6 is inserted through the blade, and is pivotally attached to the blade so that it can rotate freely, and an O-ring 21 is fitted to the end of the shaft that projects rearward to prevent the wing piece from freely falling off.

As described above, the winning device of the present invention includes a main body 1 having a case portion 5 containing a control board 7 integrally provided on the back side of a mounting board 4, and a pocket portion 2 having a rotary wing piece 17.
are formed separately, and by aligning the pocket part 2 with the front surface of the mounting board 4 of the main body, and inserting the end locking claw of the locking piece 15 that protrudes rearward into the locking part 19 and locking it. Through this assembly, the tip portion 7a of the control plate 7 protruding from the inlet 8 of the mounting board is connected to the left and right rotating blade pieces 17, 1.
The lamp 9, which faces between the rotor blades 17 and 7 and faces the front of the mounting board 4 through the opening 11, is connected to the rotor blades 17,
17 hollow parts will be penetrated.

The device of the present invention assembled in this manner is similar to conventional winning devices of this type, by inserting the case portion 5 from the front into the mounting hole provided in the game board 3, attaching the mounting board 4, and nailing it. It is fixed and assembled in the same way. This winning device accepts the ball between the closed left and right rotating blades, guides the ball onto the plate 7 facing between these two pieces, and bounces it up. The wings are opened left and right, and then when a ball enters, the base ends of the wing pieces are pushed up and closed together, and the arm 22 extending from the bottom of the control plate is pushed out backwards to move the tip 7a between the wing pieces again. It operates to prevent the device from being interrupted and opened arbitrarily.

The operation associated with this flying ball is similar to that of conventional devices, but for example, if the lighting lamp 9 that is turned on due to the activation of a detection switch installed in the middle of the path of this flying ball goes out, the device of the present invention When the locking piece 15 provided on the pocket part 2 is bent inward with a finger and the locking claw 14 at the tip is removed from the locking part 19 of the mounting board, the pocket part is attached together with the rotary blade piece 17. Since it can be removed from the front of the board, the lamp exposed on the front can be easily removed and replaced with a new one while the main body is attached to the game board.

The removed pocket portion can be easily returned to its original assembled state by aligning the tip of the locking piece with the locking portion and pressing it from the front so that it enters the locking portion and engages easily.

In the embodiment described above, the opening 11 is made into a round hole so that the tip of the lamp is exposed.
Of course, the edge of the entry port 8 may be expanded to serve as an opening from which the lamp can be seen.

Therefore, according to the present invention, when replacing the lamp, the lamp can be exposed by pressing the locking piece with your finger, and the locking piece is automatically engaged when the pocket portion is pressed against the front surface of the mounting board. Since it is assembled, the lamp can be replaced very easily, and since no tools such as a screwdriver are required for this work, maintenance and inspection can be done easily.

Incidentally, in the embodiment described above, a pair of left and right locking pieces 15 having spring properties were provided along the opening edge of the pocket portion, but in this case, only one of the locking pieces 15 had spring properties and the other was locked. The present invention can also be implemented using a locking piece that does not have spring properties corresponding to the pawl 14.

Further, in the embodiment, a through-hole locking portion 19 is provided on the mounting board 4 in correspondence with the locking piece 15, but by selecting the formation position of the locking piece, for example, it can be formed on the mounting board. It is also possible to use the edge of the entry hole as a locking portion.

Furthermore, in the above embodiment, the locking piece was provided in the pocket part, and the locking part that received it was provided on the mounting board side of the main body, but the locking piece with the claw was provided on the main body side, and the locking part that received it was provided on the main body side. Even if it is provided on the pocket side, the same effect will be obtained, and the implementation of the present invention will not be hindered.

It should be noted that, as shown in the figure, if a fitting hole 23 is provided in the mounting board and the shaft end of the support shaft 16 of the rotating blade piece is fitted into this hole, it is advantageous for positioning during assembly, and the locking piece This is advantageous because it provides a stable combination of the main body and the pocket when the pocket is latched.
