Description

  The present invention relates to an apparatus for attaching a pachinko machine to a pachinko island, and more particularly to an upper attachment apparatus for a pachinko machine frame.

  When attaching the pachinko machine to the pachinko island, after attaching the frame separately from the pachinko machine, attach the pachinko machine to this frame, and install the machine with the frame set on the pachinko machine. There is a street.

  The latter is better from the viewpoint of work efficiency, and these fixtures have been proposed. However, due to the increase in the size of the base case mounted on the back side of the pachinko machine, the space between this case and the upper plate of the underframe is small, so that it can be installed. In many cases, it cannot be installed in a set state due to interference with the instrument.

  In addition, when the pachinko machine is highly functional, the weight is as high as about 35 kg, the bed width is as large as 52 cm, and the left hinge at the pivot point with the frame is opened forward. The load is concentrated at the attachment point with the upper plate of the underframe, especially at the left attachment point. The pachinko machine is opened and closed each time it is inspected. By repeating this opening and closing, the attachment point of the fixture body and the attachment point of the frame are loosened. This loosening of the aging causes looseness of the pachinko machine, and causes the inclination of the machine and malfunctions during opening and closing.

  These mounting devices are arranged on the pachinko island so that the left and right two parts of the upper plate and the lower plate constituting the underframe are respectively mounted. However, when the pachinko base is mounted on the pachinko island, the above-mentioned viewpoint More particularly, the mounting of the upper plate on the frame is the most important, and the superiority or inferiority of the pachinko table mounting is determined depending on the performance of the upper mounting device of the frame.

  As a pachinko machine mounting device, there is Patent Document 1, which mounts a frame by lifting it with a clamping part, and can be mounted even if the thickness of the frame changes even if it is mounted by the same means In addition, there is Patent Document 3 in which the mounting strength is solved as a measure for increasing the weight of the pachinko machine described above.

JP 2007-259961 A Japanese Patent No. 4910154 JP2013-48872A

  However, Patent Document 1 is to attach the frame of the pachinko machine by sandwiching it between the upper fixed claw and the lower movable claw, but the minimum standard of the gap between the frame and the island frame is 3 mm to 4 mm, Furthermore, since the upper and lower margins are also necessary, the upper fixing pawl is limited to a thin plate, and thus the bending strength is limited. In addition, since the lower claw pushes up the frame from the lower side and regulates it with the upper claw, the upper claw is easy to bend during and after the installation of the frame, causing the above-mentioned rattling of the pachinko machine. Become.

  Also, due to the above-mentioned increase in weight, the mounting of the underframe requires a special mounting strength, so if the upper pawl is bent by the pressing force of the lower pawl and hits the island frame, the function of the angle adjustment unit will be hindered. This makes it difficult to set the tilt of the pachinko machine. In addition, when attaching the fixed part of the instrument to the island frame of Pachinko Island, it is fixed by simply screwing it from one direction, but this fastening means is easy to loosen due to repeated loading in the vertical direction when opening and closing the pachinko base. Cause rattling of the pachinko machine.

  In Patent Document 2, the frame is attached by holding the upper plate of the frame between the movable grip arm and the fixed grip base in the same manner as Patent Document 1 described above. Therefore, when the base frame is attached, the grip base is displaced upward by the pressing force of the lower grip arm to bend and become a fragile attachment state, which causes the pachinko base to be loose. In addition, since the gap between the base frame and the pachinko island is narrowed due to this bending of the grip base, the grip base pushes up the island upper frame structure and obstructs the back and forth movement of the grip base itself in the case of an installation environment where the distance is originally narrow. As a result, the inclination of the pachinko machine cannot be adjusted.

  In addition, the frame is introduced into the pachinko island by the guide of the leaf spring provided at the tip of the grip base, and the above mounting is performed. However, the grip base does not move up and down by mechanical means, but falls due to the weight of the instrument. Since it is lifted from the state, it becomes difficult to introduce the frame if there is a catch or the like.

  In addition, the adjustment range of the tilt angle of the pachinko machine is operated by moving the upper part of the frame about 15 mm back and forth, and the position of the slide tap screwed to the slide bolt is similarly moved to set the tilt angle. In this instrument, when the grip base suspended by the slide bolt is in the forward position, the balance of the center of gravity of the instrument itself, in which the slide bolt is balanced in a horizontal position, is lost, and the slide bolt is supported at the front end. The vertical hole is regulated by the lower hole edge of the vertical hole and the upper hole edge of the vertical hole on which the rear end portion is supported, and as a result, it is suspended in a downwardly inclined posture.

  Therefore, the slide base also has the same forward leaning posture, and the tip of the leaf spring that has been in contact with the pachinko island side has a weak contact force, and a gap is generated at the location, which interferes with the guide for introducing the frame. It will be.

  In addition, when the ratchet bolt is rotated and the grip fulcrum position is moved forward to attach to the thin frame, the grip end rises due to the change of the fulcrum position, and the door opening angle becomes small. Therefore, when a normal thickness frame is introduced next after mounting the thin frame, the frame collides with the grip tip, and the ratchet bolt needs to be readjusted. Since various types of pachinko machines are exchanged, the above adjustment is a complicated operation, and if the standard height at the tip of the grip breaks down, it is necessary to recheck the height before installation.

In addition, since the mounting of the frame is performed by the lever up / down operation utilizing the principle of the lever, when the frame is opened, that is, when the frame is introduced, the end of the lever stands by at a lowered position.
In addition, as described above, in the case where the base case of the pachinko machine has a large gap and the gap between the case and the underside of the base frame is small, the lever in the standby posture collides with the base case. In this state, the pachinko machine can not be introduced into the pachinko island with the pachinko machine set on the underframe, so the underframe is removed and attached separately. Also, if you force it into Pachinko Island, it will cause damage to the base case. This problem also applies to the grip in the standby posture.

  Patent Document 3 relates to the applicant of the present application. A pressure plate is provided in the gap between the upper plate and the base frame constituting the pachinko island, and the base frame is pressed from above with the pressure plate for attachment. The repulsive force acting on the upper side of the pachinko island when the pressing plate is pushed down may cause deflection depending on the structure of the island and make the mounting of the underframe weak.

  In order to solve this problem, a support plate is provided on the underside of the underframe, and the lowering of the underframe is restricted by the support plate, but it is difficult to make the height of the support plate constant. When the frame is introduced, it may collide with the frame, and the height adjustment work of this support plate is complicated and inefficient, especially when the pachinko machine is mounted on the frame. Because there is no room before and after, it is not realistic.

  In addition, since the inclination angle of the pachinko machine is determined by adjusting the inclination angle of the machine frame after the installation of the frame, it is not possible to set the inclination of the pachinko machine as a standard for the inclination of the board surface. There is.

  The present invention has been made in view of the above circumstances, and provides an attachment device that firmly attaches an upper plate of a pachinko machine frame to the pachinko island in the attachment of the pachinko machine to the pachinko machine. The purpose is to allow the desired performance to be exhibited without causing rattling or the like.

  In order to solve the above-mentioned problems, the upper mounting device for a pachinko frame according to the present invention attaches the upper plate of the pachinko frame to the upper plate that constitutes the installation area when attaching the pachinko table to the installation area of the pachinko platform of Pachinko Island An upper mounting device for a pachinko frame, which is provided as a pair on the upper and lower sides of the upper plate to be introduced below the upper plate when mounting the pachinko frame, and supports each rotation center portion with a support member with a pin.

Fixed or It is connected via a connecting means that can be moved downwardly, and is provided with a movement adjusting means that allows the support member to move in the front-rear direction of the pachinko island, and a fastening that includes the movement adjusting means and is fixed to the upper plate of the pachinko island The pachinko frame is attached by operating the opening / closing means and pressing and holding the upper plate of the pachinko frame from above and below with a clamping plate.

  The opening / closing means is provided in a vertical direction so as to be rotatable on the support member, and is screwed into the rotation bolt with one end protruding from the bottom surface of the support member and provided with an operating portion, while the rotation is restricted by the support member. The pin is configured to be opened and closed by engaging the link of the pinch plate to the lower surface of the plate nut by the bias of the spring and rotating the operation portion. The door can be closed freely with external pressure when the door is open, and even when the pachinko base frame is attached to the pachinko base frame, it can be installed by escaping upward even if the lower clamping plate interferes with the base case of the pachinko base. It was made to become.

  When the support member is connected to the movement adjusting means via the connecting means so as to be movable up and down, the tip of the upper holding plate is pressed and engaged with the lower surface of the upper plate while the holding plate is opened. Connected so that the upper plate of the underframe does not interfere with the upper clamping plate when being introduced below the upper plate, and the engagement with the upper plate is released in the closed state after the upper plate is attached, The pachinko frame can be moved back and forth.

  When the support member is fixed to the upper plate of the pachinko island by the fixing member while being fixed to the movement adjusting means, the tip of the upper holding plate is pressed against the lower surface of the upper plate with the holding plate opened. The upper plate of the underframe is not interfered with the upper clamping plate when the upper plate of the underframe is introduced below the upper plate, and the upper plate in the closed state after the upper plate is attached. The pachinko machine frame can be moved back and forth by releasing the engagement.

  The upper clamping plate is characterized in that the lower surface of the tip portion is tapered to prevent interference with the upper plate of the pachinko frame.

  The pivot support position of the clamping plate is centered on the pivot support position of the mutual engaging portion, the pivot support position of the upper clamp plate is the front, the pivot support position of the lower clamp plate is the rear, and the lower clamp plate As the relationship of the opening angle of the holding plate above the opening angle>, the upper and lower surfaces of the upper plate of the pachinko frame are pressed and held by the holding plate almost simultaneously.

  The opening / closing means is characterized in that the operation portion is driven by a torque driver having a torque adjusting mechanism so that the holding plate presses and holds the upper plate of the frame with a constant force.

  The fastening member is disposed on the upper surface of the upper board of the pachinko island, and the fastening member is secured by sandwiching the upper board from above and below through the screw from the lower side of the upper board. The moving adjustment bolt suspended from the fastening member and the connecting nut screwed to the moving adjusting bolt are inserted into the receiving portion provided on the supporting member and penetrated from the bottom of the supporting member. By connecting means screwed to the connecting nut, the support member is connected in a vertically adjustable manner so that the tip of the upper holding plate is pressed and engaged with the lower surface of the upper plate while the holding plate is open. By setting the height of the support member, the upper plate of the pachinko frame can be attached regardless of the thickness of the upper plate.

  An elastic means is disposed in the insertion gap of the connection nut in the receiving portion of the support member, and the connection nut is urged forward or rearward of the support member, and the frame of the pachinko base is the upper plate of the pachinko island. When installed on the lower side, the support member and the clamping plate are tilted up and down with the urging point of the ammunition means as a fulcrum corresponding to the height of the frame, and the upper plate of the pachinko island and the frame The mounting of the frame is performed regardless of the size of the gap.

  The fastening part of the fastening member is fastened with a screw to the lower surface of the upper plate of Pachinko Island so that the tip of the upper clamping plate is pressed and engaged with the lower surface of the upper plate of Pachinko Island. When the upper plate is introduced below the upper plate, it should not interfere with the upper clamping plate, and it will be disengaged from the upper plate in the closed state after the upper plate is installed. It is possible to adjust the movement.

  The movement adjusting means is composed of a movement adjusting bolt suspended on the fixing member and a connecting nut screwed onto the movement adjusting bolt and fixed to the support member, and the fixing member is a bearing portion for suspending and supporting the movement adjusting bolt. When the pachinko platform frame is introduced to the underside of the pachinko island's upper plate, the movement adjustment bolt is long to accommodate the height of the platform frame. It is characterized in that the frame is attached regardless of the size of the gap between the upper plate of the pachinko island and the upper frame so as to move up and down within the hole.

  Since the present invention is configured as described above, the upper plate is pressed and clamped in the upper and lower directions when attaching the upper plate of the pachinko machine, that is, the upper plate of the frame. The fragile mounting state due to the escape of force at the top of the pachinko machine can be eliminated, and in particular, the pachinko machine is heavy enough, and it has sufficient durability against the extreme concentration of load on the top of the frame when the pachinko machine is opened. Thus, the pachinko machine can be mounted without rattling for a long time.

  In addition, even if the thickness of the underframe is different in the above-described attachment, it can be attached in the same manner without the need for any other adjustment operation, and it can be attached regardless of the size of the gap between the upper plate of Pachinko Island and the upper plate of the underframe. it can.

On the other hand, the lower clamping plate escapes to the upper side even if it interferes with the base case or underframe of the pachinko machine when the above frame is introduced, that is, when the door is open. It is possible to mount with the.

  In addition, since the upper clamping plate is in a closed state after mounting the base frame and is separated from the upper plate of the pachinko island, a gap is formed, so that the inclination adjustment of the pachinko base by the movement adjusting means can be performed without resistance.

  Moreover, since the lower surface of the front end portion of the upper clamping plate is tapered, it can be guided to the mounting position without colliding even if the upper portion of the frame interferes when the frame is introduced.

  In addition, the upper and lower clamping plates having different opening angles clamp the upper plate of the frame with substantially the same pressing force in the vertical direction by setting the pivot support position between the clamping plates, so that the frame is firmly attached. .

  Further, since the opening / closing means is operated by rotating the rotating bolt from the lower side of the support member, it does not interfere with the base case or the frame when the frame is introduced.

  Further, by operating the opening / closing means with a torque screwdriver, the frame is clamped under a constant pressing condition, and the frame is attached to each table under the same conditions.

  In addition, since the fastening member is provided on the upper surface of the upper plate of Pachinko Island, and is fixed with a screw from the lower surface of the upper plate, the device itself is firmly attached, and by repeating the mounting operation of the underframe, There is no looseness at the mounting location.

  In addition, since the vertical position of the support member of the sandwiching plate is adjustable, the standby posture of the upper sandwiching plate, that is, the state of pressing engagement with the top plate of the pachinko island, is made constant regardless of the thickness of the top plate. And does not affect the mounting of the underframe.

  In addition, since the elastic member means is provided at the connection portion between the movement adjusting means and the support member, the support member and the sandwiching plate are inclined with the corresponding point as a fulcrum according to the size of the gap between the upper plate and the base frame. Even if the gap of the frame changes, it does not affect the mounting of the frame and the inclination adjustment of the pachinko machine.

In addition, the saw-like pressing portion 45 of the lower sandwiching plate 12b is strongly pressed by the stress concentrated on the sharp tip when the underframe 7 is made of wood, and when it is made of metal such as aluminum. Mounted firmly.
Although the height of the upper plate 55 changes depending on the size of the gap B and the pressing conditions of the upper and lower clamping plates 12a and 12b also change, the gap B is actually about 4 mm to a maximum of about 7 mm. Since it is absorbed by some bending of the upper plate 55, warping of the sandwiching plate 12, associating of the pivoting portion with the support member 11, the attachment strength is not affected by the change in the gap B.
Further, since the gap A is always ensured after the attachment, the problem that the upper plate 55 interferes with the upper plate 3 is prevented.

  As shown in FIGS. 10 to 11a and 11b, in the above attachment, the upper clamping plate 12a opens and closes compared to the lower clamping plate 12b because it opens in the gap A shown in FIG. 8b.

In FIG. 10, the shaft support position of the engaging portion 39 of the upper holding plate 12a, that is, the shaft hole 41 is set to the front side of the shaft holes 47 and 48 pivoted to each other, and the shaft support position of the lower holding plate 12b, Since the shaft hole 44 is on the rear side, the opening angle C of the upper clamping plate 12a is smaller than the opening angle D of the lower clamping plate 12b, and the upper plate 55 is pressed from above and below under substantially the same conditions.

In FIGS. 11a and 11b, the shaft hole 47 of the engaging portion 39 of the upper clamping plate 12 is formed as a long hole 47a so that the same action as described above is achieved. In the opened state of the clamping plate 12a of FIG. 11a, the pin 49 is positioned at the hole edge on the front side of the long hole 47a, and after closing the door and reaching the hole edge on the rear side of the long hole 47a, it is shown in FIG. Thus, the upper clamping plate 12b starts the closing operation for the first time.
As described above, since the upper plate 55 is pressed and clamped in the substantially same state from the upper and lower sides by the clamping plate 12 even if the thickness is different, the upper plate 55 is firmly attached.

  FIG. 12 exemplifies the case where the pachinko machine 1 is mounted on the underframe 7. At this time, depending on the model of the pachinko machine 1 and the opening angle of the holding plate 12, the upper side of the base case 84 may be the lower holding plate 12 b. The lower clamping plate 12b can be freely closed against the spring 34, so that the upper guide of the base case 84 escapes upward to prevent interference, and as shown in FIG. However, the operation of the movement adjusting means 14 is not hindered.

When receiving the connecting nut 21, the receiving portion 22 of the support member 11 forms an insertion gap 106 in the front-rear direction of the inside, and the connecting nut 21 is pressed forward through the insertion gap 106 with an elastic unit 107 interposed therebetween. I am doing so.
The ammunition means 107 is constituted by an inverted U-shaped leaf spring 108, and this leaf spring 108 is placed on the outer side of the receiving portion 22 by a set screw 111 in a stop hole 110 so that a curved action portion 109 faces the insertion gap 106. The nut 112 is fixed.

The fastening member 15 and the support member 11 are coupled by lifting the receiving portion 22 while pressing the leaf spring 108 against the coupling nut 21 and fitting with the bolt 81 in the same manner as described above. In the above description, when a force for tilting the support member 11 is applied due to the size of the gap B between the upper plate 3 and the frame 7, the support member 11 is engaged with the leaf spring 108 and the connecting nut 21, that is, the elastic means 107. As shown in FIGS. 16a and 16b, the urging portion is pressed and tilted in the vertical direction as shown in FIGS. 16a and 16b. As a result, the inclination of the connecting nut 21 is reduced and the screwing state with the movement adjusting bolt 65 is affected. Will not affect.
16a shows a tilted state in which the front side of the support member 11 is raised because the gap B is smaller than the standard, and FIGS. 16b and 18 show a tilted state in which the front side of the support member 11 is lowered because the gap B is large. Is shown.

  In the above, the leaf spring 108 presses the connecting nut 21 in an elastic manner so that the frame 7 is attached. Therefore, when the frame 7 is removed, the support member 11 is horizontal as shown in FIG. Return to the correct posture. Further, the same action is performed even if the leaf spring 108 is fixed to the front side in the receiving portion 22 and engaged with the front side of the connecting nut 21.

FIGS. 19 to 22 show another embodiment in which the ball plunger 113 is used instead of the plate spring 108 described above.

This bullet unit 107 operates in the same manner as described above.

In FIG. 15, a rotation prevention plate 120 for the connection nut 21 is provided on the fastening member 15 to prevent the connection nut 21 from rotating, so that the frame 7 after the attachment does not move left and right.
The anti-rotation plate 120 rises on both sides of the fastening portion 63 and is fixed to the left and right sides of the hanging portions 59a and 59b of the support plate 57, and engages with both the left and right sides of the connecting nut 21 to restrict rotation. .

23 and 24 show another embodiment of the fastening member 15.
A fastening portion 90 is formed by horizontally bending the left and right ends of the lower end portion so that a concave portion 89 in which the holding plate 12a is disposed is formed in the hanging portion 88a on the front side of the same mountain-shaped support plate 87 as described above. ing. In attaching the fixing member 15 to the upper plate 3, as shown in FIG. 24, the fixing portion 90 is disposed on the lower surface of the upper plate 3, and the front hanging portion 88a is disposed behind the upper plate 3. The flat screws 93 and 94 are fixedly attached to the respective fixing holes 91 and 92 and attached to the upper plate 3 in contact with the ends.
The upper clamping plate 12a and other members arranged in the recess 89 are used for the operation in the same manner as described above, and the upper plate 55 of the frame 7 is attached in the same manner.

FIG. 25 to FIG. 31 show another embodiment of the upper mounting device 9 using the fastening member 15 similar to the above.
30 and 31 show an example in which the connecting nut 21 is fixed to the upper plate 17 of the support member 11 so that the mounting height of the support member 11 is constant.
In this case, the height of the support member 11 is set such that the gap B between the upper plate 3 and the underframe 7 is about 4 mm as a standard. Therefore, even when the gap B changes as shown in FIGS. 30 and 31, the upper plate 55 is slightly bent, the clamping plate 12 is warped, associating the pivoting portion with the support member 11, etc., as described above. Because it is absorbed in, the mounting strength is not affected.

Further, the movement adjusting bolt 65 is hard to move in the same manner as described above due to the change in the gap B. However, as shown in FIGS. The problem is solved by drilling the long holes 123a and 123b and suspending and supporting the movement adjusting bolt 65 through the long holes 123a and 123b.
A small diameter portion 124 at the tip of the movement adjusting bolt 65 is disposed in the long hole 123a of the front hanging portion 88a shown in FIG. 25, and the rear end portion is rotatably provided in the long hole 123b of the hanging portion 88b. .
