Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a glass storage frame locking device for a pachinko machine that locks a glass storage frame that is openably and closably attached to a window of a picture frame-like front frame.

<Prior art> Most conventional locking devices for glass storage frames of pachinko machines are simply equipped with a locking piece that locks a shaft-shaped or piece-shaped engaging portion provided on the glass storage frame. For example, Japanese Utility Model Publication No. 57-8866 proposes that the groove into which the engaging part is inserted has a horizontal V-shape in order to make it easier to receive the engaging part.

<Problems to be solved by the invention> However, the conventional locking device described above forms an engagement groove in the lock plate into which the engagement part engages, and simply supports the lock plate so that it can move up and down in the vertical direction. Because of this structure, when locking the lock, there is a large resistance until the engaging part that moves horizontally engages in the engaging groove, and the lock will not lock smoothly, especially if the height of the engaging part is even slightly off. I couldn't do it.

In addition, in conventional locking devices, a lever for moving the locking plate up and down is provided protruding rearward from the locking plate, so it is not possible to store the locking device in a stacked state with the locking device assembled to the metal frame, or to When transporting from a subcontractor factory to a pachinko machine assembly factory, it is bulky and gets in the way, and the lever itself can be hit or bent, causing damage, which can interfere with the operation of the locking device itself. There were other drawbacks.

<Means for solving the problem> This proposal was proposed in view of the above.A holding frame is attached to the inner periphery of the window of the picture frame-like front frame, and a glass storage frame is attached within the holding frame so that it can be opened and closed. , in a pachinko machine in which an engaging part provided on the free end side of the glass storage frame is locked by a locking device provided on the holding frame, a vertically elongated lock along one side of the inner circumferential surface of the holding frame; The auxiliary plate is fixed, and the front end edge of the auxiliary locking plate has a guide edge whose upper and lower edges are inclined so that the distance increases as the distance approaches the opening edge of the holding frame. An engaging part storage notch is formed which has a regulating edge positioned at the rear and whose upper edge and lower edge extend in a substantially horizontal direction, and the auxiliary locking plate has a vertically elongated locking plate at the upper end of the opening. The locking plate is mounted so as to be movable up and down by fitting a mounting pin into an elongated operating hole having an open lower end, and this locking plate has a locking claw portion that projects in the vertical direction at a position facing into the engaging portion storage notch. The front edge of the locking claw portion is inclined as a pressing force receiving portion, and the rear edge of the locking claw portion is sloped as a locking portion, so that the locking claw portion enters the engagement portion storage notch. The locking plate is biased by a biasing member in the direction, and the operating hole is opened at an angle so that the lower end of the opening is located forward of the upper end of the opening, and the locking plate has a tip of a release lever. The part is rotatably attached to a shaft, an operating protrusion is formed at the tip of the release lever, and a receiving part that can engage with the operating protrusion is formed on the locking plate, so that the rear part of the release lever faces upward. It is possible to convert between the first state and the second state in which the rear part of the release lever extends and the operating piece engages with the receiving part of the locking plate.

<Function> In the glass storage frame locking device configured as described above, when the release lever is folded to the first state with the rear side facing upward, the release lever hardly protrudes from the rear end edge of the locking plate and becomes bulky. Never.

When the glass storage frame is pressed toward the front frame, the tapered guide edge guides the engaging part of the glass storage frame to a predetermined height, and the engaging part whose vertical height is regulated by the regulating edge. The pressing force receiving portion of the locking claw portion is pressed against the bias. When the inclined pressing force receiving portion is pressed by the engaging portion, the locking plate moves in the vertical direction while moving toward the front side against the biasing force of the biasing member. Therefore, the engaging portion is smoothly locked as it is guided into the inclined locking portion of the locking claw portion.

Further, after rotating the release lever and converting it to the second state in which the rear part thereof extends behind the locking plate and the operating protrusion of the release lever engages with the receiving part of the locking plate, the rear part of the release lever is rotated. When you press down to unlock, the locking plate moves forward and vertically in the same way as above, so the engaging part of the glass storage frame is pushed forward and the locking claw of the locking plate is pushed forward. removed from the department.

At the same time, as shown in FIG. 7, the shaft 57 protruding from the lower left end of the glass storage frame 5 is fitted into the bearing hole 40 of the lower bearing 41.

Locking device 58 that locks the glass storage frame described above
is the attachment of the lock attachment surface portion 49 of the holding frame 4,
As shown in FIG. 2, it is comprised of a locking auxiliary plate 60 having mounting pins 59, 59 projecting laterally, and a locking plate 61 fitted into the mounting pins 59, 59.

The locking auxiliary plate 60 has guide edges 62, 62 on the front edge thereof, the upper edge and the lower edge of which are inclined so that the distance increases closer to the opening edge of the holding frame 4;
Approximately U-shaped engagement part storage notches 64, 64 are formed on the upper and lower sides, and have regulating edges 63, 63 located rearward of 62 and having upper and lower edges extending substantially horizontally, Mounting pins 59, 59 are erected between these engaging portion storage notches 64, 64, and the spring hook portion 6
5, a locking receiving piece 66 for the lower substrate 7 is formed on the lower front edge, and a receiving part 67 is formed on the rear edge by partially cutting and raising it.

On the other hand, the locking plate 61 attached to the locking auxiliary plate 60 so as to be vertically movable has its front edge cut out at a position corresponding to the engagement part storage notch 64 of the locking auxiliary plate 60, so that the locking plate 61 can be moved upwardly. The locking claw portions 68, 68 are formed, and the front edge of each locking claw portion 68 is sloped in a smooth arc shape to form a pressing force receiving portion 69, and the rear edge of the locking claw portion 68 is sloped. An opening pressing portion 71 is formed by slanting the upper edge of the cutout portion toward the opening. Between the cutout portions of the locking plate 61 are diagonally elongated operating holes 72, 72, which have the same pitch as the mounting pins 59, 59, and whose lower ends are located forward (to the right in FIG. 8) of the upper ends of the openings. At the same time, the spring hook part 73 is cut and raised, and the rear edge is
An operating protrusion 75 as an operating portion formed at the tip of a release lever 74 whose tip is rotatably pivoted.
A receiving portion 76 that fits and receives is formed.

To attach the locking plate 61 configured as described above to the locking auxiliary plate 60, insert the mounting pins 59, 59 into the operating hole 7.
2, 72, and a coil spring 77 provided as a biasing member is attached to both spring hanging portions 65, 73.
The locking plate 61 is urged upward by being stretched between the two. When the locking plate 61 is attached in this manner, the locking claw portions 68, 68 each face into the engagement portion storage notch 64 and come to rest, as shown in FIGS. 8 and 9.

On the other hand, the engaging portion 78 of the glass storage frame 5 that is locked by the locking device 58 described above is provided on the free end side of the glass storage frame 5, and as shown in FIGS. The plate material is slightly smaller than the vertical distance between the regulating edges 63 of the cutout portions 64.

Therefore, when the free end side of the glass storage frame 5 is pressed against the front frame side by hand, as shown by the chain line in FIG. The lock can be locked without any problem due to this action. That is, since the glass storage frame 5 is pivoted on the left side, when it is in the open state, 2
The weight of the sheets of glass and the glass storage frame 5 is supported only by the shaft on the left side, and the position of the engaging portion 78 on the right side shifts downward. However, when the glass storage frame 5 is pressed toward the front frame side, the upper end or the lower end of the engaging portion 78 comes into contact with one of the guide edges 62 of the engaging portion storage notch 64, and when the glass storage frame 5 is further pressed, Due to the inclination of the guide edge 62, the engaging portion 78 receives a pressing force in the vertical direction, is corrected to a predetermined height, and moves forward. Therefore, the engaging portion 78 comes into contact with the pressing force receiving portion 69 of the locking claw portion 68 . When the glass storage frame 5 is further pressed toward the front frame in this state, since the pressing force receiving part 69 is inclined, a downward force acts on the locking claw part 68, and this force causes the locking claw part 68 to release the coil spring. It descends against the bias of the actuating hole 77 and moves forward slightly due to the inclination of the operating hole 72. In this way, the engaging portion 78 of the glass storage frame 5 is connected to the locking claw portion 68.
moves forward while descending, and when the lower end of the engaging portion 78 passes the tip of the advancing locking claw portion 68, the locking claw portion 68 moves upward and retreats due to the bias of the coil spring 77, and the locking claw portion The locking portion 70 of 68 contacts the lower end of the engaging portion 78 to smoothly lock the glass storage frame 5. In addition, since the locking portion 70 of each locking claw portion 68 is inclined and is urged upward by the coil spring 77, the locking portion 70 is always in point contact with the engaging portion 78 and is not locked in the locked state. The gap between the joining part 78 and the locking part 70 can be eliminated. Further, since the vertical distance between the regulating edges 63 of the engaging portion storage notch 64 is formed to be slightly larger than the vertical length of the engaging portion 78, it is possible to prevent the glass storage frame 5 from vibrating rattling.

On the other hand, the glass storage frame 5 locked as described above
To open the opening, as shown in FIG. 8, the release lever 74 is first rotated from the folded storage state (first state) shown by the dotted line to the operating state (second state) shown by the solid line. The protrusion 75 is engaged with the receiving portion 76 . Then, the release lever 74 is pressed downward by hand to push down the locking plate 61. Locking plate 6
1 is an operating hole 7 into which mounting pins 59, 59 are loosely fitted;
2 and 72 are inclined, so it descends while moving forward. Therefore, the locking claw parts 68, 68 are easily disengaged from the engaging parts 78, 78. In addition, the locking plate 6
1 is sufficiently lowered, since the opening pressing portion 71 of the locking plate 61 is inclined, the opening pressing portion 71 pushes the locking portion 78 forward as shown in FIG. Therefore, a large gap is formed between the free end side of the unlocked glass storage frame 5 and the front frame 1, and the glass storage frame 5 can be easily opened wide by inserting a hand into this gap.

As described above, if the release lever 74 is made foldable from the tip end pivoting part, when transporting with the locking device 58 attached to the holding frame 4, for example, when transporting from a subcontract factory to an assembly factory, etc., it is possible to open the release lever 74. It can be folded so that the lever 74 does not protrude rearward (first state). Therefore, the release lever 74 does not get in the way even when stacked on top of each other, and a large number of them can be stacked in a stable state, making transport and handling easier than before, and making efficient use of space when storing them. Can be used.

In addition, although the locking claw portion 68 of the present invention is provided upward in the above embodiment, it may be provided downward.
The inclination of the pressing force receiving portion is not limited to an arc shape, but may be linearly inclined.

<Effects of the invention> As explained above, according to the invention, the release lever can be converted into the first state in which it is folded upward relative to the locking plate and the second state in which it is extended rearward. Even if it is a semi-finished product that has been assembled to the holding frame at the factory but has not yet been assembled to the front frame,
The release lever can be placed in a first folded state. Moreover, since the release lever can be folded from the tip that is pivoted to the locking plate, the folded release lever protrudes toward the rear side of the locking plate, compared to the conventional release lever that is folded from the middle of the release lever. length becomes shorter.

Therefore, a large number of semi-finished products in which the glass storage frame locking device is assembled to the holding frame can be stacked in a stable state, and since the stacked state does not take up much space, space-efficient storage becomes possible. , can be transported efficiently.
Therefore, it does not get in the way in a narrow factory. Furthermore, even during various inspections during the manufacturing process, the release lever does not protrude to the rear side of the locking plate, so it does not get in the way and inspection work can be carried out smoothly.

In addition, after the glass storage frame locking device is assembled to the front frame and the pachinko machine is completed, when the release lever is changed to the second state, the operating protrusion engages with the receiving part of the locking plate, so the pachinko machine Both during the assembly process and after installation at a pachinko parlor, the locking plate can be reliably lowered by rotating the release lever in the direction in which the protruding rear part descends.

In addition, with the present invention, even if the height position of the engaging part of the glass storage frame is slightly misaligned, when the glass storage frame is pressed toward the front frame, the guide edge moves the engaging part of the glass storage frame to a predetermined position. Guide to height. Therefore, it is possible to press the glass storage frame toward the front frame side without pressing while supporting it with your hands, such as repeating the locking operation many times or lifting the glass storage frame with your hands or pushing it down with your hands. You can easily lock it with just the key.

Further, in the present invention, since the locking portion of the locking claw portion is inclined, the locking claw portion can easily lock the engaging portion, and there is no play in the locked state.

Furthermore, in the present invention, the operating hole of the locking plate is opened at an angle so that the lower end of the opening is positioned forward than the upper end of the opening, so when closing the glass storage frame, the locking claw part of the locking plate is opened. It moves forward once, then retreats, and then moves up and down to invite the engaging portion of the glass storage frame. Therefore, compared to the conventional device in which the locking claw portion simply moves down, the engaging portion of the glass storage frame can easily engage the locking claw portion of the locking plate, and
Engages quickly and reliably. After the engaging portion engages with the locking pawl, the locking plate moves backward, and since the locking portion is inclined, the engaging portion of the glass storage frame may be slightly shifted up and down. Even if it does, it will be locked quickly and reliably.

Furthermore, when unlocking, when the locking plate is moved in the vertical direction against the biasing force of the biasing member, the locking plate moves forward because the operating hole is inclined. Therefore, the glass storage frame engaging portion is easily and quickly removed from the locking claw portion, and the locking plate itself moves forward, making it easy to push the glass storage frame forward.

In short, in the glass storage frame locking device according to the present invention, the elongated operating hole of the locking plate is opened at an angle in the front and back, so when the glass storage frame is closed, the locking claw part of the locking plate is opened. When the engaging part of the glass storage frame is brought in and locked, and when it is opened, the locking claw part pushes out the engaging part of the glass storage frame to unlock it, and the engagement part and the locking claw part are Not only does the locking/unlocking operation become smooth, but even if the height position of the engaging part of the glass storage frame is slightly misaligned, the locking/unlocking operation of the glass storage frame can be done reliably and easily. be able to.
