[0003] Such a mounting device has a mounting structure of a conventional general pachinko gaming machine, that is, a mounting structure in which the pachinko gaming machine is mounted by directly fixing the pachinko gaming machine to an island frame by screws or nails at its outer peripheral frame. In comparison, it has the following advantages. The workability of mounting is significantly improved. Generally, a pachinko gaming machine is mounted with a certain inclination as shown in FIG. 12, but the inclination can be easily and accurately set. Further, this inclination can be adjusted later if necessary, and this adjustment can be made accurately.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to further improve the above-described mounting device. More specifically, it is an object of the present invention to further improve the inclination adjusting function of the pachinko gaming machine in the above-described attachment device, and to make it possible to more accurately set an intended inclination more easily. At the same time, another object of the present invention is to provide a clamp used in combination with a mounting device.

[0005]

For this purpose, the present invention enables one-touch tilt adjustment by improving a holding block and an adjusting tool in the above-described mounting device. Specifically, a mounting device according to the present invention includes a mounting member, a holding block provided on the mounting member, a rack member with rack teeth held by the holding block so as to be able to move back and forth, and orthogonal to the rack member. The pinion teeth are formed so as to be insertable into the adjustment hole formed in the holding block in the orientation, and the pinion teeth meshing with the rack teeth of the rack member while being inserted into the adjustment hole are formed. An attachment for moving the member back and forth, a locking means provided on the holding block to fix the rack member at a desired position, and a support provided at a tip of the rack member; Is fixed to the frame of the gaming machine installation base unit, while the rack member fixes and supports the outer peripheral frame of the pachinko gaming machine through the support portion thereof. No attachment of pachinko machines to the installation base unit, and has a basic structure that enables adjusting the inclination state of the pachinko gaming machine by longitudinal movement of the rack member.

In addition to this, a positioning groove is provided on the inner peripheral surface of the adjusting hole of the holding block, a stopper projection is provided on the holding block, and a shaft portion having pinion teeth formed thereon, and An adjusting tool is formed by a structure including a positioning projection provided so as to be able to move out and forth, and an operating section connected to one end of the shaft section, and an outer peripheral frame is provided on the operating section of the adjusting tool. A rotating drum is provided inside the outer peripheral frame so as to be rotatable and fixed at a desired rotation angle with respect to the outer peripheral frame, and a locking projection protruding from the outer peripheral frame is provided. Then, the adjustment tool is inserted into the adjustment hole with the position of the positioning tool along the positioning groove, and the locking tool is moved to the stopper projection of the holding block through the operation part. By rotating the rack member to a contact state, the rack member is moved back and forth in accordance with the desired rotation angle state with respect to the outer peripheral frame of the rotating drum.

In the mounting apparatus of the present invention, an adjusting tool in which the rotation angle state of the rotary drum with respect to the outer peripheral frame is set to a desired value in advance is simply inserted into the adjusting hole of the holding block and turned. Thus, the rack member can be moved forward or backward by a fixed amount, and the tilt can be adjusted with one touch. This makes it possible to operate without looking at the movement of the rack member, for example.
The operation inside the narrow and difficult-to-work island can be performed easily without any skill. That is, in addition to the various advantages of the mounting device disclosed in Japanese Patent Application No. 62-58888 described above, the mounting device of the present invention can perform one-touch tilt adjustment, so that even an unskilled person can easily perform accurate tilt adjustment. Brings a great advantage that

In the mounting device as described above, a pair of engagement holes are provided at an interval corresponding to the width of the stopper projection on the outer peripheral frame of the operating portion of the adjusting tool, and the engagement projections are selectively provided in these engagement holes. It is preferable that the engaging protrusion is engaged with one engaging hole when the rack member is advanced, and the engaging protrusion is engaged with the other engaging hole when the rack member is adjusted backward. . In this way, a linear correspondence is obtained between the rotation angle of the rotary drum with respect to the outer peripheral frame and the longitudinal movement of the rack member. For example, when a scale relating to the inclination is provided on the outer peripheral frame or the rotary drum, the scale is continuously changed. As a matter of fact, it can be made easier to use.

[0009] Further, with respect to the mounting device as described above,
By making it possible to easily adjust the rotation angle between the outer peripheral frame and the rotary drum in the adjusting tool, it is possible to make the device easier to use. For this purpose, the present invention utilizes a spline structure so that the rotation angle can be adjusted and fixed by the spline tooth pitch. Specifically, an inner peripheral spline tooth is formed on the inner peripheral surface of the outer peripheral frame, and an outer peripheral spline tooth corresponding to the inner peripheral spline tooth is formed on the outer peripheral surface of the rotating drum. The angle state is fixed.

According to the present invention, in the spline structure, a flat portion having no inner spline teeth is provided on the inner peripheral surface of the outer peripheral frame with a width wider than the width of the outer spline tooth forming portion of the rotary drum. The urging means is interposed between the rotating body and the rotating body, and the rotating body is pushed against the biasing means, so that the outer spline tooth forming portion of the rotating body is positioned in correspondence with the flat portion of the outer peripheral frame. The rotation angle of the rotating drum with respect to the frame is adjusted, and the rotating drum is returned by the urging force of the urging means when the desired rotation angle state is set, so that the desired rotation angle state is fixed by meshing the two spline teeth. I have. By doing so, the rotation angle can be adjusted and fixed by the spline structure more easily.

Further, in the present invention, in such a spline structure, a key projection is provided on the outer periphery of the rotary drum so as to be able to move in and out in a biased manner, and the outer spline tooth forming portion of the rotary drum corresponds to the flat portion of the outer peripheral frame. In this state, this key protrusion corresponds to the position of the inner peripheral spline tooth formation portion of the outer peripheral frame,
Thus, the key projection is engaged with and disengaged from the inner peripheral spline teeth when the rotating body is rotated. According to this structure, the rotation operation at the spline tooth pitch can be easily performed by engaging and disengaging the key projection with the inner peripheral spline teeth.

Further, according to the present invention, in the above mounting device, a storage chamber is provided in the rack member,
A stopper claw is provided inside the storage chamber so as to be able to protrude and retract, and the stopper claw projects from the outer periphery of the rack member and abuts against the outer surface of the holding block so that the temporary advance limit of the rack member can be set. I have. The provisional advance limit of the rack member in such a structure is a standard inclination of a general pachinko game machine (for example, the upper side of the pachinko game machine is located behind the lower side, that is, the inner side of the island is divided into four quarters (13.5 mm). ) It functions as a reference for setting the angle of the rearward tilt. In other words, the stopper claw is attached to the outer surface of the holding block under the condition that the fixing position of the mounting member to the frame of the gaming machine installation base unit and the fixing position of the support portion to the outer peripheral frame of the pachinko gaming machine are in a predetermined relationship. By making contact, a standard inclination can be set. When the inclination is smaller than the standard inclination, that is, when the rack member is adjusted to move forward, the stopper claw is retracted into the storage chamber to make it possible.

The above mounting device can be used to fix the lower part of the pachinko gaming machine to the lower frame of the gaming machine installation base unit, that is, the island bottom plate. Used to fix the upper part to the island top plate. When the mounting device according to the present invention is used for fixing the upper portion of the pachinko game machine, it is preferable to use a clamp for fixing the lower portion of the pachinko game machine.

A clamp according to the present invention includes a base, a pressing body, an operation lever, and an adjuster assembled to the base, and is fixed to the frame of the gaming machine installation unit via the base. Then, in this state, the pressing body is pressed against the outer peripheral frame of the pachinko gaming machine by rotating the operation lever, thereby fixing the pachinko gaming machine to the pachinko gaming machine unit, and fixing the outer periphery by the pressing body. The distance between the pachinko gaming machine and the base can be adjusted by the adjuster in a state where the pressing of the frame is released.

A feature of this clamp is that it has an adjuster, which allows adjustment of the distance between the pachinko gaming machine and the base, that is, the front-rear positional relationship between the lower portion of the pachinko gaming machine and the frame of the gaming machine installation base unit. . This is particularly effective in relation to the standard inclination setting function using the stopper claws of the rack member described above. That is, the standard inclination setting by the stopper pawl involves the fixing position of the mounting member to the frame of the gaming machine installation base unit and the fixing position of the support portion to the outer peripheral frame of the pachinko gaming machine. Since the outer peripheral frame is generally made of wood, an error is likely to occur in each of the fixed positions, and if there is an error, the standard inclination setting by the stopper claw is disturbed. Therefore, in order for the stopper pawl to work effectively, an adjusting means for the fixed position error is required, and the adjuster of the clamp functions as this adjusting means.

With regard to such a clamp, since the outer peripheral frame of the pachinko gaming machine is generally made of wood, the clamping force may be loosened when vibration is applied to the pachinko gaming machine for some reason. Therefore, such a phenomenon can be effectively prevented by providing the pressing body with a pressing rod and urging the pressing rod in the pressing direction by the urging means.

Further, as shown in FIG. 10, the outer peripheral frame 46 is provided with a tilt scale 61, while the rotary drum 37 is provided with an arrow mark 62 indicating a scale value selected from the tilt scale 61.
The tilt scale 61 is a scale using a shakukan method that is commonly used in the pachinko industry as the tilt angle of the pachinko gaming machine. The inclination scale 61 is attached in a manner similar to the standard inclination in the pachinko industry, which is one-fifth (the upper side of the pachinko machine is behind the lower side, ie, 13.5 in the island).
In a state where the arrow mark 62 points to the rear inclination (retracted by 1 mm), the positioning projection 42 of the shaft portion 35 is located at the middle point between the mounting holes 53a and 53b as shown in FIG.

The mounting device according to the present invention as described above is used as follows. First, in order to attach a pachinko gaming machine to the island U in FIG.
As can be seen in FIGS.
Then, the upper outer peripheral frame Fu of the pachinko gaming machine P is fixed and supported by the screws via the support member 32 at the tip of the rack member 3.

In order to adjust the inclination of the pachinko gaming machine P in the state of being mounted as described above, the adjusting tool 4 is used. More specifically, first, the adjustment of the set of the adjuster 4, that is, the operation unit 36, is performed so that the rotational relationship of the rotating drum 37 with respect to the outer peripheral frame 46 corresponds to the intended inclination. For this purpose, the rotating body 37 is pushed into the state shown in FIG. 7 against the bias of the compression coil spring 60. In this state, the outer spline teeth forming portion of the rotating cylinder 37 corresponds to the position of the flat portion 49, so that the engagement of the outer spline teeth 55 with the inner spline teeth 51 is released, and the rotating cylinder 37 is freely rotated. be able to. Using this state, the rotating drum 37 is rotated by a required angle. During this rotation, the key projection 56 repeatedly engages and disengages with the inner peripheral spline teeth 51,
Thus, the rotating operation of the rotating drum 37 can be performed at the spline tooth pitch. The setting of the necessary angle
This is performed by aligning the arrow mark 62 of 7 with the inclination scale 61 of the outer peripheral frame 46. For example, in the case where the inclination is reduced to ３ from the ４ of the standard inclination setting, the arrow mark is set to the target scale value of ３ (shown by a two-dot chain line in FIG. 10). . Further, in this case, the adjusting tool 4 is connected as shown in FIG.
Since it is rotated as shown by the arrow in the middle, the locking projection 54 is attached to the attachment hole 53a on the right side as viewed in the state of FIG. If the inclination is increased from the quarter, the rotation direction of the adjusting tool 4 is reversed.
The locking projection 54 is attached to 3b.

After completing the above adjustment, the shaft 35 of the adjuster 4
Is inserted into the adjusting hole 17 of the holding block 2 until the stopper projection 19 comes into contact with the operation portion 36 or the locking projection 54 comes into contact with the holding block 2. This insertion is performed by the shaft 35
The positioning projections 42 are arranged along the positioning grooves 18 of the adjustment holes 17, that is, the positioning projections 42 are fitted into the positioning grooves 18. Then, an operation for retracting the stopper claw 34 of the rack member 3 to enable the rack member 3 to advance is performed. That is, the inclination of the stopper claw 34 is 4/5.
In the state where the rack member 3 is larger than the weight, the tip of the rack member 3 abuts on the holding block 2 in a state where the inclination is 4/5 (FIG. 2). An operation for canceling this state is performed.
When the rack member 3 can be advanced in this way, the adjusting tool 4 is rotated until the locking projection 54 comes into contact with the stopper projection 19 of the holding block 2. Then, the rack member 3 moves forward by an amount corresponding to this rotation, so that the rack member 3 is fixed at that position by being tightened by the lock means 21. As a result, a slant of three-thirds is set for the pachinko gaming machine P.

Next, an embodiment of the clamp will be described. The clamp according to one embodiment of the present invention includes a base 71, a pressing body 72, and an operation lever 73 as seen in FIG.

The base 71 has a structure in which a saddle portion 75 and an adjuster mounting portion 76 are erected on a flat plate portion 74 for screwing to the island lower plate Ud of the island U in FIG. Attach the adjuster bolt 77.

The pressing body 72 is formed by assembling a pressing rod 79 having a bolt structure at the tip of an L-shaped frame 78, and the base end of the frame 78 is connected to a saddle 75 of the base 71.
To be connected in a link.

The operating lever 73 has its distal end pressed by the pressing body 7.
In addition to being connected to the second frame 78 in a link manner, the intermediate portion is provided so as to be linked to the saddle portion 75 of the base 71 by a link piece 81.

This clamp clamps the lower outer peripheral frame Fd of the pachinko gaming machine P with the island lower board Ud by the pressing body 72 in the state shown in FIG. Works to fix the On the other hand, when the operation lever 73 is pulled up as shown by the arrow X, the pressing body 72 rises as shown by the arrow Y, and the fixing is released. By adjusting the adjuster bolt 77 in this state, the pachinko gaming machine P and the base 71 are adjusted.
Can be adjusted.

FIG. 11 shows a clamp according to another embodiment, which is basically the same as that of the above embodiment, except that a compression coil spring 83 is combined with a pressing rod 79 of the pressing body 82 as an urging means. The difference is that the compression rod spring 83 constantly urges the pressing rod 79 in the pressing direction.

[0035]

As described above, according to the present invention, the operation of attaching a pachinko gaming machine to an island is greatly simplified, and the setting of the inclination of the pachinko gaming machine attached to the island and the re-adjustment thereof are unskilled.
