Description

[Detailed Description of the Invention] [Industrial field of application] This invention is to supply pachinko balls from a pachinko ball ball storage tank of a pachinko game arcade to each pachinko machine and ball lending machine. It is about the road.

[Prior Art] A connection hole for connecting a corner gutter, which is a main component of a conventional pachinko ball supply path, and a chute, which is a gutter for dropping balls from the corner gutter, is almost as shown in Figs. It is formed as shown. In FIG. 7, the connection holes 22 with the chute 27 are provided along the both side walls 3 of the bottom part 4 of the corner gutter 1 in a substantially quadrangular shape, approximately 5 mm apart from the both side walls 3, and at equal intervals. A chute 27 as shown in FIG. 8 is connected to the corner gutter 1 in accordance with the position of the connecting hole 22, and the chute outlet 30 shown in FIG. 9 is connected to a ball storage tank of a pachinko machine or ball lending machine not shown. It is in communication.

Further, the connecting hole 22 has a size of about 50 mm × 40 mm, and the chute 27 is mounted so that the ball receiving portion 23 of the chute 27 is positioned directly below this, and the mounting thereof is performed as shown in FIG. The fitting 29 of the chute 27 is inserted into the chute holding fitting 26 provided on the lower surface of the bottom portion 4 of No. 1.

[Problems to be Solved by the Invention] Since the conventional technique is as described above, the size of the ball receiving portion 23 of the chute 27, particularly the width thereof, is the connecting hole 2 of the corner gutter 1.
The size of the pachinko machine is increased in accordance with the size of 2, so that the chute 27 also becomes large, the number of balls accumulated in the chute 27 increases, and the distribution speed also slows down. Along with this, the number of balls that must be supplied to the entire facility will increase.

Further, since the flow of the balls becomes a curve as shown by an arrow A in FIG. 7, the effective width thereof also decreases in inverse proportion to the size of the width of the connecting hole 22, which reduces the flow efficiency of the balls.

The purpose of this invention is to reduce the required amount of balls in the entire pachinko game hall by effectively circulating the balls flowing through the ball supply path without causing ball clogging,
Furthermore, it is to facilitate the attachment of the chute to the corner gutter.

[Means for Solving the Problems] This invention for solving the above problems will be described with reference to the drawings showing an embodiment. It is shown in FIGS. 1 to 6 that the bottom part 4 of the pachinko ball supply gutter 1 is provided. , A connection hole 2 formed along the side wall 3 and having a width slightly larger than the diameter of the pachinko ball and connected to the chute 7. The connection hole 2 stands at the upstream end 1a of the corner gutter 1. Control plate 8 raised; a blocking portion 8a for blocking the pachinko balls from entering the connecting hole 2 from the upstream end 1a, and a guide provided inside the connecting hole 2 along the side wall 3 The control plate 8 including a portion 8b; downstream of the guide portion 8b of the bottom portion 4,
Also, an inclined portion 5 which is formed in an elongated shape in communication with the connecting hole 2; an inclined portion 5 having an inclination that becomes lower as it approaches the side wall 3; a virtual extension of the guide portion 8b to the downstream side of the corner gutter 1. The inclined portion 5 including the line 8c within the range; the ball receiving portion 7b for reaching the ball, which is connected to the connecting hole 2, and the width 7d of the ball passage 7c at the downstream thereof are each slightly larger than the diameter of the pachinko ball. The chute 7 which is formed large;
It is a pachinko ball supply path characterized by consisting of.

The control plate 8 is a pachinko ball supply path provided on the chute 7 connected to the connection hole 2.

The control plate 8 is a pachinko ball supply path provided on the bottom 4 of the corner gutter 1.

The connecting hole 2 is a supply path for the pachinko balls which is formed correspondingly at the end portions on the side wall 3 side of the corner gutter 1.

Further, the chute 7 has an engaging portion 9a which engages with a holding portion 9b provided outside the side wall 3 of the corner gutter 1 and an engaging portion 7a which engages with the bottom portion 4 from the connecting hole 2. This is a supply path for the pachinko balls.

[Operation] Since the present invention is constructed as described above, the corner gutter 1
The pachinko ball flowing down is blocked by the blocking portion 8a of the control plate 8 and guided by the guide portion 8b without entering from the upstream end 1a of the connecting hole 2 and along the virtual line 8c extending the guide portion 8b. As it enters the inclined portion 5 including the imaginary line 8c, it can be prevented from flowing in obliquely, and inevitably drops into the connecting hole 2 effectively and stably from almost the lateral direction. Therefore, the pressure from the upstream of the balls is not applied, and only a slight pressure of the balls from the side can be applied, so that the jamming of the chute 7 due to the meshing of the balls can be prevented. Then, as described above, the connecting hole 2 has an elongated hole shape having a width slightly larger than the diameter of the pachinko ball, and the connecting hole 2 and the ball receiving portion 7b for reaching the ball of the chute 7 and the ball passage 7c downstream thereof. Since the width is formed slightly larger than the diameter of the balls, it is possible to reduce the amount of balls held in the game arcade.

Further, since the width of the connecting hole 2 is formed to be slightly larger than the diameter of the ball, the chute 7 can be downsized.

Further, since the control plate 8 as described above is provided in the connection hole 2, even if the positions of the connection holes 2 are provided along the side wall 3 so as to correspond to each other, the effective width of the ball flow is slightly reduced. Kaku 1
The flow of balls flowing inside is almost linearized, and the distribution effect can be enhanced.

Furthermore, since the holding portion 9b and the locking portion 9a that engage with each other are provided on the outside of the side wall 3 of the corner gutter 1 and the chute 7, respectively, the chute 7 can be mounted in the corner gutter 1 extremely easily. .

[Embodiment] An embodiment of the present invention will be described with reference to FIGS. 1 to 6 of the accompanying drawings. As shown in FIG. 1 and FIG.
Angles provided with connecting holes 2 in the shape of a slot according to the position of the pachinko machine are provided at equal intervals and at mutually corresponding positions along the side walls 3 slightly apart from the side walls 3 of the corner gutter 1 (about 5 mm). Gutter 1
And a chute 7 shown in FIGS. 4 and 5 that engages with each of the connection holes 2 and connects the corner gutter 1 with a storage chamber (not shown) of each pachinko machine or ball lending machine. .

The shape of the connecting hole 2 is approximately L with the upstream end of the ball flow forming an R.
It is shaped like an oblong hole whose width is slightly larger than the diameter of the ball.

When installing the gutter 1 on the upper part of the chute 7, the gutter 1
There is provided a control plate 8 which penetrates the connecting hole 2 of the connecting hole 2 and projects perpendicularly to the bottom surface of the corner gutter 1. The shape of the control plate 8 is a guide portion 8b along the inner long side portion 6 of the connecting hole 2 and its guide. The blocking portion 8a is curved from the upstream end of the portion 8b toward the side wall 3 of the corner gutter 1 along the upper end of the connecting hole 2, and has a substantially L-shaped cross section.

The blocking portion 8a has a pachinko ball at the upstream end 1a of the connecting hole 2.
This prevents the balls flowing down in the chute 7 from interlocking with each other due to the pressure of the balls flowing down in the corner gutter 1 to prevent the ball jamming.

Reference numeral 5 denotes an inclined portion formed so as to communicate with the bottom portion 4 of the square gutter 1 and to the connecting hole 2 from the side, and an inclination that becomes lower toward the side wall 3 is formed. An imaginary line 8c extending the guide portion 8b in the downstream direction is formed by the inclined portion 5
It is formed within the range of.

The guide portion 8b, together with the inclined portion 5, prevents the balls from obliquely flowing into the connecting hole 2 and allows the balls to flow substantially from the side. As a result, the pressure of the balls flowing down in the corner gutter 1 can be made very small to reach the balls inside the connecting hole 2, and as a result, the flow-down stop due to the bridging of the balls on the ball receiving portion 7b of the chute 7 can be prevented. You can eliminate it from happening. The control plate 8 may be provided on the chute 7 as described above, or may be provided on the upstream end 1a of the connecting hole 2 of the corner gutter 2. 2a in FIG.
Indicates a playground of balls. Next, in FIG. 4 to FIG.
Is a chute, on which the control plate 8 and the locking portion 9a are provided. In FIG. 6, 11 is a fixed plate and 12 is a chute outlet. Further, in the figure, 9b is a holding portion provided on the outside of the side wall 3 of the square gutter 1 so as to lock the locking portion 9a. Reference numeral 7a is a hooking portion provided on the chute 7, and is adapted to hook onto the bottom portion 4 from the downstream end portion of the connecting hole 2.

And the ball receiving portion 7b of the chute 7 and the ball passage 7c
7d has a width slightly larger than the diameter of the pachinko ball.

To describe the operation of this embodiment, first, the chute 7
Is inserted from the downstream end of the connecting hole 2 of the gutter 1 so as to be hooked on the bottom 4 and the locking portion 9a is attached to the gutter 1.
It is locked to the holding portion 9b of the side wall 3. This is done with almost one-touch ease.

The chute 7 is connected to a pachinko machine or ball lending machine (not shown).

When a pachinko ball is supplied to the corner gutter 1 from the upstream side, the ball flows down, and the blocking portion 8 of the control plate 8 in the connecting hole 2 is cut off.
A is cut off. Then, next, it flows down along the guide portion 8b, advances along an imaginary line 8c extending the guide portion 8b, enters the inclined portion 5 formed by including the imaginary line 8c within the range, and this inclined portion 5 falls and enters the connection hole 2.

[Advantages of the Invention] The invention is configured as described above, and the virtual line 8 is formed by extending the guide portion 8b following the blocking portion 8a to the downstream side of the corner gutter 1.
By placing c within the range of the inclined portion 5, the balls are
It is possible to prevent the liquid from obliquely flowing into the connecting hole 2, and it is possible to effectively and stably enter the connecting hole 2 from a substantially lateral direction. For this reason, the pressure of the ball flowing down from the upstream of the corner gutter 1 can be made extremely small, and it is possible to reliably prevent the flow stop due to the ball meshing in the ball receiving portion 7b in the connecting hole 2.

Then, in such a state, the width of the connecting hole 2 is formed to be slightly larger than the diameter of the ball, and the width 7d of the ball receiving portion 7b and the ball passage 7c for reaching the ball of the chute 7 is slightly larger than the diameter of the pachinko ball. By being formed, the amount of balls possessed by the chute 7 becomes smaller than in the conventional case, and the number of balls possessed by the entire game arcade can be reduced. Further, the flow of the balls becomes closer to a straight line than that of the conventional one, and the flow can be effectively performed.

Further, unlike the conventional case, the holding portion 9b for attaching the chute 7 to the corner gutter 1 is also provided on the side wall 3 so that the bottom portion 4 does not need to be processed by welding or the like, and the smoothness thereof is disturbed to disturb the flow of balls. Never.
