Description

[Detailed description of the invention] <Industrial field of application> The present invention faces the surface of the front frame of a pachinko machine and decorates the area around the lock, which is a part of the locking device that locks the front frame and the glass frame. This invention relates to lock accessories for pachinko machines.

<Prior art> As is well known, the lock of a locking device for a pachinko machine that locks and unlocks the front frame or glass frame is formed in a cylindrical shape with a keyhole on the front end, and the rear end is attached to the front. It is fixed to the mounting board on the back of the frame. To attach this lock to the front frame of a pachinko machine, the lock is passed from the back side through a through hole formed in the front frame so that the keyhole on the front end face faces the surface of the front frame.

However, when the lock is left attached in this manner, the front end portion of the lock is exposed on the surface of the front frame, which not only looks unsightly, but also makes it easy for unauthorized members such as piano wire to be inserted through the through hole.

Therefore, in the past, a lock plate made of a flat plate made of plastic with a lock hole through which the lock could be inserted was attached to the surface of the front frame, and the front end of the lock protruding from the surface of the front frame was inserted into the lock hole. By exposing the lock, the area around the front end of the lock is protected (for example, Japanese Utility Model Publication No. 39-31222).

<Problems to be solved by the invention> By the way, in recent pachinko machines, in order to improve the interest of the game, there is a tendency to enlarge the game section in order to install a large variable display device and a large prize winning device on the game board. There is. However, since there are regulations regarding the width of the machine frame, the only way to expand the gaming area is to narrow the width of the vertical frame material of the front frame. Therefore, as the width of the edge plate increases, the width of the lock plate inevitably becomes narrower, and the size of the lock plate is such that a part of the lock plate rests on the top surface of the edge plate, making it difficult to install the lock plate. This causes instability and a decrease in strength.

In addition, if conventional lock plates are molded thickly, dents will occur due to solidification and shrinkage, so they are molded from a single plate and decorated with a single color, which is the base color of the plastic, making them weak in strength and insufficient. It is not possible to achieve a decorative effect.

In a pachinko game parlor, the front frame or glass frame can be unlocked by inserting a key into the keyhole of the conventional lock installed as described above and turning it to the right or left. In this case, when the staff member opens the front frame to inspect the back mechanism, etc., he or she often lifts the key inserted into the keyhole and rotates the front frame forward using the hinge as a fulcrum. .

In this way, when the clerk rotates the front frame by lifting the key with one hand without placing his left hand on it, not only does the weight of the front frame itself, but also the game board, launcher, and back mechanism attached to the back side of the front frame. The weight will be applied directly to the lock.

However, as described above, the conventional lock only has its base fixed to the mounting board, and the front end portion is not held in any way. For this reason, if the weight of the front frame or back mechanism is applied to the front end of the lock, this load will be concentrated at the base of the lock, and if repeated over a long period of time, it will damage the connection area between the lock and the mounting board (lock base). Problems such as damage to the product are likely to occur.

If the connection between the lock and the mounting board is damaged, it may cause the lock to malfunction.
Repair work is extremely troublesome because not only the lock and mounting board but also the entire locking device must be replaced.

Furthermore, if the damaged lock starts to move when unlocking, the force that tries to lift the front frame up to the lock plate will loosen the fixing screws and cause the lock plate to fall off the front frame, which is an inconvenience. will appear.

<Means for solving the problem> The present invention was developed to solve the above problem. A locking device for locking the frame and the glass frame is provided, and the lock of the locking device is inserted into a through hole drilled in the front frame,
This is a pachinko machine in which the front end of the lock faces the surface of the front frame, and the main decorative member attached to the front frame corresponding to the front end of the lock has a main decorative member attached to the peripheral edge of the back surface of the main decorative member. A rib is provided to protrude from the front frame surface side to form an unformed space open to the front frame surface side so as to have a predetermined height from the front frame surface side, and a lock hole is opened through which the front end portion of the lock faces, and A front-open operating recess is formed around the lock hole, with the front edge of the lock hole facing the bottom, and a portion corresponding to the border material on the back side of the main decorative member has a plate thickness of the border material. A notch with a slightly larger longitudinal width is formed in the longitudinal direction of the main decorative member, an engaging part into which another member fits is provided in at least a part of the main decorative member, and a sub-decorative member is attached to this engaging part. It is fitted and fitted.

<Function> The present invention has ribs protruding from the periphery of the back surface of the main decorative member to form an unformed space that is open to the front frame surface side and has a predetermined height from the front frame surface. The strength of the decorative components themselves has increased significantly,
Further, the notch allows the front frame to be firmly fixed in a fitted state to the surface of the front frame. Therefore, the main decorative member can withstand a large load. Therefore, even if the load of the front frame or back mechanism is applied to the tip of the lock when the clerk opens the front frame, this load can be absorbed by the lock decoration, which is firmly attached to the mounting board of the locking device and the front frame. The lock can be distributed and received by the lock, and the load can be prevented from being concentrated on the lock base.

In addition, by forming an unformed space with one side open at a predetermined height from the front frame surface, an operating recess can be formed around the lock hole, which not only increases the rigidity of the main decorative member itself. This eliminates the possibility that the tips of the fingers gripping the key come into contact with the front end of the decorative member when the clerk operates the key to unlock the key, making the operation easier.

Furthermore, the main decorative member and the colorful sub-decorative members are assembled into one piece, thereby making the design more complex and diversified.

<Example> Hereinafter, the present invention will be described with reference to an example shown in the drawings.

As shown in FIG. 1, the pachinko machine 1 has a machine frame 2.

In order to attach the locking device 12 configured as described above to the front frame 4, as shown in FIG. The lock 20 is inserted from the back side of the front frame 4 to make the front end of the lock 20 protrude from the front surface of the front frame 4, and in this state, the mounting board 14 is fixed to the back side of the front frame 4 with wood screws or the like.

A lock decoration 24 according to the present invention is attached to the surface of the front frame 4, and the lock decoration 24 holds the front end portion of the lock 20 to reinforce the locking device 12. This prevents the insertion of an unauthorized member, and improves the appearance around the front end portion of the lock 20.

According to the embodiment shown in FIG. 5, the lock decoration 24 is composed of a main decoration member 25, and a first sub-decoration member 26 and a second sub-decoration member 27 that are engaged with and attached to the main decoration member 25.

The main decorative member 25 is made of plastic material colored in an appropriate color such as red or yellow, and has ribs protruding from the periphery of the back surface of the main decorative member 25 so as to have a predetermined height from the surface of the front frame 4. It has the shape of a vertically elongated frame with an open back and an unformed space 28 that opens toward the side. By forming the unformed space 28 by protruding the peripheral rib on the back surface of the main decorative member 25, the strength of the main decorative member 25 is significantly improved even if the material is plastic. An inclined surface 30,
30 and a lower surface 31, and a lock hole 33 is formed in the lower surface 31 of this operation recess 32.
will be established. This lock hole 33 has a size and shape into which the front end portion of the lock 20 described above can fit, and a short cylindrical lock holding portion 34 is formed at the inner peripheral edge of the lock hole 33. Further, on the front part 29 of the main decorative member 25, a recessed first engaging part 35 is provided above the lock hole 33.
A through-hole-shaped second engaging portion 36 is formed below each lock hole 33 . Note that the first and second engaging portions 35, 3
6 is formed to correspond to the shape and size of the first and second auxiliary decorative members 26 and 27, respectively. Therefore, when the plastic plate-shaped first sub-decorative member 26 is engaged and attached to the first engaging portion 35 of the main decorative member 25 from, for example, the front side, the first sub-decorative member 26 and the first engaging portion 3
5, the surface of the first auxiliary decorative member 26 and the surface of the main decorative member 25 can be made flush with each other.
6 by fitting the second sub-decorative member 27 from the back side.
The secondary decorative member 27 and the second engaging portion 36 can be engaged and attached.

Moreover, the first and second lock accessories 24 according to the present invention
When the secondary decorative members 26, 27 and the main decorative member 25 are molded from plastic materials of different colors, the lock decoration 24 becomes rich in color and the decorative effect can be enhanced, as shown in FIG. Furthermore, if the second sub-decorative member 27 is used as a lens for a lamp (not shown) and the lamp is exposed inside, the decorative effect can be further enhanced when the lamp is lit.

In addition, when attaching the first and second sub-decorative members 26 and 27 to the first and second engaging portions 35 and 36, respectively, if they are attached with adhesive or fixed with screws, both sub-decorative members can be attached. 26 and 27 are the main decorative members 25
Since the locking device 24 is firmly and integrally engaged with the locking device 24, the overall strength of the locking device 24 is significantly increased.

On the other hand, on the back side of the main decorative member 25 of the lock decoration 24 according to the present invention, a portion corresponding to the bordering material 9 fixed to the surface of the front frame 4 has a thickness slightly larger than that of the bordering material 9. A notch 38 having a longitudinal width is formed in the longitudinal direction so that when the lock decoration 24 is fixed to the front frame 4, the back surface of the main decorative member 25 does not rest on the edge decoration 9 and shake. Make it.

The lock decoration 24 having the above-mentioned configuration is attached to the front frame 4.
To attach the lock 20 to the front frame 4, fit the front end of the lock 20 protruding from the surface of the front frame 4 into the lock hole 33 of the main decorative member, and in this state, insert a nail or wood screw into the fastening holes 37, 37 and attach the lock 20 to the main decorative member. 25 is fixed to the surface of the front frame 4.

When the main decorative member 25 is fixed to the surface of the front frame 4 as described above, the holding part 34 of the lock hole 33 is attached to the lock 2.
Hold the front end portion of 0. In addition, the cutout portion 38
Since the main decorative member 25 and the edge decoration material 9 do not interfere with each other, the lock decoration 24 is not attached to the front frame 4 obliquely and does not wobble, and can be firmly attached in a stable state.

Then, in the locking device 12 equipped with the lock decoration 24 as described above, the clerk inserts the key 39 into the keyhole 33 opened on the front end surface of the lock 20, and rotates the key 39 about 90 degrees to the right or left. Rotate and hook 1
After removing keys 7 and 17 from supports 16 and 16, remove key 39.
Even if you open the front frame 4 by rotating it toward you while lifting the front frame 4, the load applied to the tip of the lock 20 is absorbed by the lock holding part 34 of the strong main decorative member 25 and the mounting board 14 on the back of the front frame 4. It can be distributed and received. Therefore, the load applied to the connection portion between the lock 20 and the mounting board 14 (the base of the lock 20) is significantly reduced.

Note that when the key 39 is inserted into the keyhole 33 and rotated, as shown in FIG.
Since the front vertical space is wide open, when operating the key 39, fingers and hands do not touch the main decorative member 25, and the key 39 can be easily rotated.

Further, when unlocking the glass frame 10 by rotating the key 39 inserted into the vertically elongated keyhole 33 by approximately 90 degrees,
If the position of the lock 20 and the size of the key 39 are set so that the lower end of the key 39 does not hit the glass frame 10,
As shown in FIG. 6, the glass frame 10 can be opened while the key 39 remains in the horizontal direction.

In another embodiment shown in FIG. 7, an auxiliary rib 40 is formed inside the main decorative member 25, that is, in the unformed space 28, and this auxiliary rib 40 is brought into contact with the surface of the front frame 4. . In this way, when the auxiliary ribs 40 are provided on the main decorative member 25, the main decorative member 25
Since the strength of the lock 5 can be further increased, it becomes possible to deal with a narrower front frame, and the holding power of the front end portion of the lock 20 by the lock hole 33 can be further increased.

Note that the number and shape of the sub-decorative members 26 and 27 are not limited to those in the above embodiment, and may be relatively thin metal plates such as aluminum plates.

<Effects of the invention> As explained above, according to the invention, ribs are provided protruding from the peripheral edge of the back surface of the main decorative member and are opened to the front frame surface side at a predetermined height from the front frame surface. Since the unformed space is formed, the strength of the main decorative member itself can be significantly increased, and moreover, the main decorative member can be stably fixed to the front frame surface by the cutout portion of the main decorative member. Therefore, even if the staff member opens the front frame while lifting the key inserted into the keyhole, the front frame,
Even if the weight of the game board, back mechanism, etc. is added to the lock, this load will be borne by the lock's mounting board, and
The divided load can also be sufficiently received by the main decorative member, and the load concentrated on the connecting portion between the lock and the mounting board can be halved compared to the conventional one. Therefore, damage to the connection portion (lock base) between the lock and the mounting board can be eliminated. Furthermore, even if a half-reduced load is applied when opening the front frame, the key ornament with increased strength remains firmly attached and will not fall off.

Further, according to the present invention, by engaging and attaching the main decorative member and the colorful sub-decorative member, for example, the ground color of the main decorative member and the ground color of the sub-decorative member can be made to be different colors. As a result, the design can be made more complex and diversified, and it is possible to provide a colorful lock decoration that has not been seen before, and the decorative effect can be significantly enhanced compared to the past.

Furthermore, the present invention provides ribs protruding from the back surface of the main decorative member to form an unformed space that is open to the front frame surface side and has a predetermined height from the front frame surface. Not only can it have high rigidity, but also an operating recess can be formed around the lock hole, which provides good operability when rotating a key inserted into the key hole, and has high practical value.
