Reference numeral 2 denotes a droplet, which is provided on the bottom wall of the pachinko ball container 1, and a plurality of droplets are provided corresponding to ball distribution locations. Reference numeral 3 denotes a chute, which has a receiving part 4 corresponding to the drop opening 2 at the upper end of one end, and a discharge part 5 at the lower end of the other end. The chute 3 is inclined downward from the receiving part 4 toward the discharge part 5,
The width is gradually narrowed, and the distal end is opened downward to form a discharge section 5.

Near the receiving portion 4 of the chute 3 is a hook-shaped plate-like locking portion 6 that protrudes from the upwardly projecting end toward the tip.
This locking part 6 is inserted into the drop opening 2 from below the pachinko ball container 1 and is suspended from the bottom wall 7 of the pachinko ball container 1. Another locking part 8 is provided at the upper part of the other end of the chute 3 near the discharge part 5, and is configured to be fixed to another part of the bottom wall 7 of the pachinko ball container 1 by a fixing member 9. ing. The locking part 8 is formed of a crank-shaped plate member that projects upward from a distal end thereof and further protrudes in the distal direction, and is joined to the discharge part 5 by a reinforcing plate 10 . 11 is a reinforcing plate provided on the upper surface of the chute 3.

The fixing member 9 is attached to the lower part of the side edge 12 of the pachinko ball container 1 by a mounting portion 13, and has a holding portion 14 that extends from there to the bottom surface of the container 1 and holds the locking portion 8 under the bottom surface. The plate spring 15 presses the locking part 8, and the plate spring 15 presses the joint part 1.

To install the pachinko ball chute configured as described above, insert the locking part 6 at the tip of the chute 3 into the drop opening 2 of the pachinko ball container 1, such as a ball distribution gutter or tank installed at the site, and attach it to the bottom wall. 7, then lift the holding part 14 of the fixing member 9 from below the locking part 8 and insert it into the engaging piece 17, and bring the upper end piece of the holding part 14 into contact with the lower surface of the side edge 12 of the container 1. , the attachment part 13 is inserted and fixed, and the locking part 8 is pressed down by the leaf spring 15 to attach it.

As described above, the chute 3 is attached and fixed to the pachinko ball container 1, and the pachinko balls in the container 1 fall from the drop opening 2 into the receiving part 4, pass through the inside of the chute 3, and are discharged from the discharge part 5.

[Problem that the invention attempts to solve]

However, in the conventional pachinko ball chute as described above, in order to increase the pachinko ball storage space in the chute 3 and to smoothly discharge the balls from the chute 3, the chute 3 is configured so that its width gradually becomes narrower. Therefore, many pachinko balls are arranged in a row on the receiving part 4 side, and are ejected in a single row from the ejecting part 5. Therefore, when the discharge of pachinko balls from the chute 3 is stopped, if a large number of pachinko balls fall from the container 1 in order to supply pachinko balls to other chute 3, they will fall into the chute 3 where the discharge is stopped. The pressure of the pachinko balls is applied through the mouth 2, and as a result, the pachinko balls are pressed against the squeeze wall 24, which gradually narrows in width, and become clogged, making it impossible to smoothly discharge the pachinko balls from the chute 3, especially in humid seasons. There was a problem.

This idea was developed to solve the above problem, and is a pachinko ball that can be smoothly ejected without clogging even when a large number of pachinko balls flow inside the container when the ejection of pachinko balls is stopped. The purpose is to provide a ball shot.

[Means for solving problems]

This invention consists of a wide part having a receiving part corresponding to the drop opening of a pachinko ball container, a discharge part connected via a squeeze part having a squeeze wall so that the width gradually narrows from this wide part, and this discharge part. an alignment groove formed through the wide part and the bottom of the throttle part so as to communicate with the wide part, and a plateau-like bottom part extending from the side wall and the throttle wall side of the wide part to connect to the upper part of the wall on one side of the alignment groove. and an inclined surface provided on a portion of the plateau-shaped bottom on the squeeze wall side so as to be inclined toward the receiving portion side.

[Effect]

In the pachinko ball chute of this invention, when the pachinko balls fall from the drop opening of the pachinko ball container such as the ball distribution gutter or tank, the pachinko balls accumulate in the wide part from the receiving part of the chute and flow from the plateau-like bottom into the alignment groove. They enter, move to the discharge section in an aligned state, and are smoothly discharged. In this case, since an inclined part is formed in the part of the plateau-like bottom on the squeeze wall side, the pachinko balls in this part receive a force in a direction that causes them to flow down toward the receiving part, and the pressing force against the squeeze wall increases. becomes weaker. For this reason, even when the ejection of pachinko balls is stopped, a large number of pachinko balls flow inside the pachinko ball container, and even when a large number of pachinko balls are pushed into the stopped chute, the pachinko balls on the sloping part are pushed into the squeeze wall. The pressing force is small, the clogging on the squeeze wall is eliminated, and the pachinko balls are pushed out smoothly the next time they are ejected.

〔Example〕

Fig. 1 is a front view showing an embodiment of this invention, Fig. 2 is a sectional view thereof, Fig. 3 is a sectional view thereof, and Figs. 4 to 7 are - to -.
It is a sectional view, and the same reference numerals as in FIGS. 8 to 10 indicate the same or corresponding parts.

The basic structure of the chute 3 is almost the same as that of the conventional one, but the receiving part 4 has a wide part 21.
It is connected to a separate discharge section 5 via a squeeze section 22 . A substantially upright side wall 23 is provided on one side of the wide portion 21, and a curved and inclined aperture wall 24 is provided on one side of the aperture portion 22. At the bottom through the wide part 21 and the squeeze part 22,
A substantially continuous linear alignment groove 26 communicating with the discharge portion 5 is provided along the other upright side wall 25 .

Wide part 21 and squeeze part 22 adjacent to this
A part of the alignment groove 26 is provided with a plateau-like bottom portion 27 extending from the upper end of the alignment groove 26 toward the side wall 23 and the squeeze wall 24 side, and sloped surfaces 27a, 27b, horizontal surface 27c, and sloped surface 27d are formed from the receiving portion 4 side. ing. When the chute 3 is installed, the inclined surface 27
a is inclined from the side wall 23 side toward the alignment groove 26 side, and the inclined surface 27b is connected to the horizontal surface 27c and the inclined surface 27b.
The inclined surface 27a is provided on the throttle part 22 and is inclined from the throttle wall 24 side toward the receiving part 4 side. Slanted surface 2 of squeeze portion 22
An alignment groove 26 is provided on the discharge part 5 side from 7d, and the squeeze wall 2
It extends to the 4 sides to form a retention section 28.

The reinforcing plate 11 protrudes high so as to come into contact with the bottom of the container 1, and the abutting portion serves as a leaf spring 11a. The leaf spring 15 is attached to cover the upper side of the locking part 8, and the leaf spring 15 on the fixing member 9 side is omitted. 5a is a slanted wall forming the upper end of the discharge part 5, 29 and 30 are flanges, and L is a horizontal surface. The other configurations are the same as those shown in FIGS. 8 to 10.

The pachinko ball chute constructed as described above is installed and used in substantially the same manner as conventional ones. At this time, if the chute 3 is installed in a direction opposite to the pachinko ball container 1, such as a ball distribution gutter that is inclined with respect to the horizontal plane L, the leaf spring 11a of the reinforcing plate 11 will elastically come into contact with the bottom of the container 1. This prevents the locking portion 8 from lifting up. Further, the plate spring 15 is fixed to the fixing member 9.
When the locking part 8 is lifted by the holding part 14, it is interposed between the bottom of the container 1 and the locking part 8 to prevent the locking part 8 from wobbling.

In the installed state, when pachinko balls fall from the drop opening 2 of the container 1, the balls accumulate in the wide part 21 from the receiving part 4 of the chute 3, and fall into the plateau-like bottom part 2.
7, enter the alignment groove 26, move to the discharge section 5 in an aligned state, and are smoothly discharged. In this case, the pachinko balls flow down in the directions of the arrows at the plateau-like bottom 27 and enter the alignment grooves 26. At this time, since the inclined part 27d is formed in the part on the squeeze wall 24 side, the pachinko balls in this part receive a force in a direction such that they flow down toward the receiving part 4 side, and the pressing force against the squeeze wall 24 is weak. Become. Therefore, when the ejection of pachinko balls from the ejection unit 5 has stopped, other chute 3
Even when a large number of pachinko balls flow through the container 1 in order to distribute the balls to the stopper 3 and are thereby pushed into the stopped chute 3, the pachinko balls on the inclined portion 27d are not pressed against the squeeze wall 24. The force is small, the squeeze wall 24 is no longer clogged, and the pachinko balls are smoothly ejected the next time. Especially the plateau-like bottom 2 as in the example.
When the slopes 27a and 27b are formed on the side of the receiving part 4 of 7, the pachinko balls in this part receive a force toward the alignment groove 26, so the pachinko balls on the slope 27d easily move toward the receiving part 4, There will be even less clogging. Further, by providing the retention portion 28 in the middle of the alignment groove 26, clogging in this portion is reduced.

[Effect of idea]

According to the present invention, alignment grooves are provided in the wide part and an inclined surface is formed in the plateau-like bottom, so that when the ejection of pachinko balls from the chute is stopped, a large number of pachinko balls move inside the pachinko ball container. Even if it flows, it has the effect of being able to be discharged smoothly without getting clogged in the chute.
