Description

[Detailed description of the invention] The present invention relates to a support device that supports a passage gutter for replenishing pachinko balls from a supply source to each pachinko machine, and in particular finely adjusts the support height of the passage gutter to achieve the optimum This invention relates to a support device for a pachinko ball replenishment passage gutter that can be set to an inclination angle.

To supply pachinko balls to a large number of pachinko machines installed in a row at a store, generally the pachinko balls are fed from a supply source through a channel-shaped passageway gutter, and then distributed to each pachinko machine through a distribution gutter that divides the flow from the gutter to each pachinko machine. Pachinko balls are supplied to each player.

However, in the conventional installation of passageways, a U-shaped hanging frame was suspended from the ceiling of the building, and a long passageway gutter was placed on this hanging frame to support it. Since the inclination angle of the passageway gutter is fixed, it is extremely difficult to install it at the optimal inclination angle for the flow of pachinko balls when replenishing pachinko balls, and the inclination angle of the passageway gutter can be adjusted after installation. This makes it extremely difficult to make fine adjustments to make the pachinko balls flow smoothly, making it extremely difficult to transfer the pachinko balls in good conditions.

In view of this, the present invention is a support device for a pachinko ball replenishment passageway gutter, which makes it easy to set the inclination angle of the pachinko ball supply passageway gutter to an optimal value, and also simplifies the installation work of the passageway gutter. It was created with the purpose of providing.

In order to achieve the above object, the present invention includes a support rod that is suspended from a fixed part of a building or the like at a predetermined interval;
A support arm whose base is vertically slidably fitted to the support rod, rack teeth formed in the vertical direction on the support rod, and a gear pivotally supported by the base of the support arm and meshed with the rack teeth. and a tightening member that allows the gear to be fixed to the support arm, and the passage gutter is placed and fixed on the support arm.

The present invention will be explained below with reference to embodiments shown in the drawings.

The support device according to the present invention, as shown in FIG. A mounting seat 3 for fixing to a ceiling or the like is bent at a right angle, and a mounting hole 4 is bored in the mounting seat 3 for inserting a set screw or the like.

As can be seen from FIG. 2, the support rod 1 has a U-shaped cross section, and an inwardly bent edge 5 is formed on the edge of the - side 1a, and a bent edge 5 facing inward is formed on the edge of the other side 1b. Rack teeth 6 are formed in the vertical direction.

The support arm 2 has a base 2a formed in a U-shape in cross section, and cutouts 7, 7 that engage with the bent edges 5 of the support rod 1 on the upper and lower sides 2b, 2C of the base 2a. As shown in the figure, it is supported in a cantilever manner so as to be slidable up and down by fitting it into the support rod 1 so that it can be slid up and down.

A gear 8 is pivotally supported on the base 2a of the support arm 2, and when the base 2a is fitted to the support rod 1 as described above, the gear 8
are adapted to mesh with the rack teeth 6.

The gear 8 can be attached by fitting the gear 8 onto the screw rod 9 as shown in Figure 3 and then screwing it into the screw hole 10 formed in the support arm 2, or by screwing it into the screw hole 10 formed in the support arm 2, as shown in Figure 5. As shown, the gear 8 is attached to the screw rod 9 inserted into the support arm 2.
The gear 8 may be loosely fitted into the supporting arm 2, and then the wing nut 11 is screwed in, and by tightening the wing nut 11, the gear 8 can be fixed to the support arm 2.

The support arm 2 in this embodiment is formed so that the inclination in the width direction of the passage device 12 placed thereon can also be adjusted.

That is, as shown in Figures 3 and 4, respectively,
The base end of the support plate 13 is pivotally connected to the support arm 2 by a pin 14,
Elongated holes 15 and 16 are formed in the support arm 2 and the side plate 13a of the support plate 13, and the long holes 15 and 16 are inclined in opposite directions. A set screw 17 is inserted through the intersection of the long holes 15 and 16, and can be fastened with a nut 18.

Therefore, by loosening the ratio screw 17 and sliding it to either the left or right, the free end of the support plate 13 will be displaced up and down using the pin 14 as a fulcrum due to the change in the intersection of the elongated holes 15 and 16. It is possible to correct the inclination of the passage machine 12 in the width direction.

In the figure, reference numeral 19 denotes a stop rod insertion hole arranged in a row on the upper surface of the support plate 13, into which legs 20a, 20a of a U-shaped stop rod 20 made of an elastic material as shown in the fourth figure are inserted. This stopper rod 20 is used to fix the passage device 12 to the support plate 13.

Note that this adjusting means can be added as necessary and does not necessarily need to be provided, and this adjusting means and passageway machine fixing means may have other configurations as well.

Since the present invention has the above-mentioned configuration, the support rods 1 are suspended from the building at required intervals, and the support arms 2 of each support rod 1 are set at a required height position.

Next, pass the passage device 12 onto each support arm 2 and attach the stop rod 20.
is fixed by making it straddle the passageway machine 12 and inserting its leg parts 20a, 20a into the locking rod insertion holes 19, 19.

In this case, when it is necessary to adjust the height of the support arm 2 of each support rod 1, loosening the screw rod 9 or wing nut 11 of the support arm 2 releases the restraint of the gear 8, so the support arm 2 upwards or downwards, the gear 8 moves to the rack tooth 6.
It rotates while being engaged with the shaft, allowing it to move up and down.

If the set screw 9 or wing nut 11 is tightened when the optimal height position is reached, the gear 8 is fixed to the support arm 2 at that position, so the gear 8 functions as a stopper and the support arm 2 to be fixed in that position.

If the passageway machine 12 is tilted in the width direction, loosen the set screw 17 and move the set screw 17 in accordance with the direction of the inclination of the passageway machine 12. Due to the inclination of the long holes 15 and 16, the free end of the support plate 13 moves up and down, allowing the passage device 12 to be adjusted horizontally.

In this way, the present invention involves fitting the base of a support arm into a support rod suspended from a fixed part of a building or the like so that it can slide up and down, and forming a gear pivotally supported at the base of this support arm on the support rod. The gear is configured to be fixed at an arbitrary position by a tightening member, and the passage machine is supported on this support arm, so that the gear can be set with the support arm at the optimum height position. By fixing the support arm, the support arm can be strongly cantilevered at that position, and the height position of the support arm can be adjusted virtually steplessly due to the above action.
The passageway machine supported by this can be easily set at the optimal inclination angle, and the support arm is supported on a cantilever, making it extremely easy to place and fix the passageway machine, and when raising and lowering the support arm. Since fine adjustments can be made simply by operating the tightening members such as wing nuts, the adjustment work can be easily performed even in narrow spaces.The structure is extremely simple, making it easy to manufacture and suitable for mass production. It has various effects such as being suitable and being available at a very low cost.
