SUMMARY OF THE INVENTION The above-mentioned conventional electronic accessory of the game board has the following problems.

When the lead wire 3a is inserted into the mounting hole 6 and hits something on the back side, as shown in FIG.
Is light, so it rises. When mounting a human, it can be done while holding it so that it does not float up, or by separating the lead wire 3a from an obstacle, but when trying to temporarily assemble it with a robot or the like for automation, it should be lifted up. Will interfere with the next step. The present invention has been made in view of the above problems, and an object thereof is to provide an electrical accessory for a game board that can prevent lifting and prevent automation problems even when there are long lead wires. To do.

[0006]

In order to achieve the above-mentioned object, the invention according to claim 1 is arranged on the surface of the game board while the lead wire is led out to the back side through a mounting hole formed in the game board. An electrical accessory that is provided on the game board surface and has a body portion that includes the electrical equipment, and a flange portion that can be closely contacted in parallel with the game board and that has a screw hole that penetrates toward the game board surface. , A configuration provided with an elastic temporary fixing piece that is extended to the mounting hole side with respect to the main body portion and can be forcefully inserted into the mounting hole is there.

In the invention according to claim 1 configured as described above, the lead wire is led out to the back side from the mounting hole formed in the game board and disposed on the surface of the game board. Since the main body part provided is arranged on the game board surface,
The flange portion is closely contacted in parallel with the game board, and is screwed and fixed by a screw hole that penetrates toward the game board surface. However,
When the main body is set to the mounting hole position before this screwing, the elastic temporary fixing piece extending from the main body to the mounting hole is forcibly inserted into the mounting hole, and at the time of the forcible insertion, the game concerned. Engage the board and temporarily fix it. Therefore, the main body is temporarily held at a predetermined position before screwing, and even if the lead wire comes into contact with something on the back side of the game board, it does not float up.

Such a main body holds electrical components,
The shape can be appropriately changed depending on the type and function of the electrical component, and the main body portion may be composed of a plurality of parts to support the electrical component. Also, the electrical component does not necessarily have to be on the front side of the game board, and may be inside the mounting hole. In any case, the lead wire may be attached to the front side of the game board while being led out to the rear side.

The elastic temporary fixing piece may be any one as long as it can be forcibly inserted into the mounting hole and engages with the game board at the time of forcible insertion, and its shape is various. As an example thereof, in the invention according to claim 2, in the electrical accessory of the game board according to claim 1, the elastic temporary fixing piece becomes narrower toward the front end and is stepped outward on the rear end side. And a wedge-shaped engaging portion formed with a wedge-shaped inclined surface so that the tip of the engaging portion can enter the mounting hole, and the wedge-shaped inclined surface is in sliding contact with the inner peripheral surface of the mounting hole. The arm portion has a length such that the step portion at the rear end of the joint portion is locked to the opening edge on the back side of the mounting hole.

In the invention according to claim 2 configured as described above, the elastic temporary fixing piece is formed of the arm portion and the engaging portion. Here, since the arm portion supports at least the tip of the engaging portion so that it can be inserted into the mounting hole, if it is aligned by a robot or the like and pushed toward the mounting hole, it will start entering the mounting hole without being caught. However, the wedge-shaped inclined surface which can enter the mounting hole interferes with the mounting hole, and the inclined surface is pressed so as to be in sliding contact with the inner peripheral surface of the mounting hole. However, when the main body is pushed in to a predetermined position, the stepped portion at the rear end of the engaging portion reaches the opening edge on the back side of the mounting hole, and the engaging portion moves outward due to the reaction force that interfered with the inner peripheral surface. Is pushed out and the step portion is caught on the opening edge on the back side. As a result, it will be temporarily fixed and will not come out even if you try to pull it back.

While such a shape is simple and fulfills a sufficient role, it is needless to say that the shape is not limited to this. For example, in this example, it is adapted to engage with the opening edge on the back side of the attachment hole, but it may be formed in a claw shape so as to engage with the peripheral surface of the attachment hole. Further, while having a tubular body formed to be slightly smaller than the mounting hole, elastic folds are formed on the peripheral surface of the tubular body, and while bending the folds, the folds are made relative to the inner peripheral surface of the mounting hole. It may be locked by locking. Further, the number of such elastic temporary fixing pieces can be changed appropriately.

Although the mounting position on the game board will be finally determined by screwing, the alignment may be important. As a preferred example in such a case, the invention according to claim 3 is the invention according to claim 1 or claim 2.
In the electrical accessory of the game board described in any one of the above, the elastic temporary fixing piece is configured to be aligned by entering a positioning recess formed on the side of the mounting hole. In the invention according to claim 3 configured as described above, the positioning recess is formed on the side of the mounting hole, so that when the elastic temporary tacking piece is forced into the mounting hole, the positioning recess enters the positioning recess. , Is aligned with a predetermined position.

Of course, such a positioning recess is formed corresponding to the engaging position of the elastic temporary fixing piece, and at that time, it may be formed in a tapered shape so as to be guided to a predetermined position. For example, if the cross section of the elastic temporary fixing piece is formed into a chevron-shaped projection and the positioning recess is formed in a mortar shape, an action of guiding the apexes of each other to come into contact with each other occurs. Naturally, this positioning recess is formed at the opening edge on the back side of the mounting hole, but in such a case, the actual configuration of the game board can be preferably used. That is, the invention according to claim 4 is the electrical accessory of the game board according to claim 3,
The gaming board is made of plywood and has a peelable thin plate attached to the back surface thereof, and the positioning recess is formed by peeling the thin plate.

Usually, the game board itself is formed of plywood and a peelable thin plate is attached to the back surface. Then, this thin plate is hollowed or peeled off into a predetermined shape for another alignment. In view of such an entity, in the invention according to claim 4 configured as described above, the thin plate is peeled off at the opening edge of the rear surface of the mounting hole to form a positioning recess.

[0015]

As described above, according to the present invention, since the elastic temporary fixing piece extending toward the mounting hole is provided so that it can be held at a predetermined position before being screwed, it is lifted by the lead wire. It is possible to provide an electronic accessory for a game board that can prevent automation from being hindered.

According to the second aspect of the invention, it is possible to make the shape of the elastic temporary fixing piece simple and sufficient. Further, according to the invention of claim 3, the positions can be aligned at the same time, which facilitates automation.
Further, according to the invention of claim 4, it is possible to extremely easily perform the alignment while using a normal game board.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing a winning ball detector 10 as an electrical accessory of a game board according to an embodiment of the present invention.

In FIG. 1, the winning ball detector 10 is provided at a predetermined position of a game board G, which will be described later, and a main body portion 20 provided at a winning passage position of a game ball, and a rear surface side of the main body portion 20. A hollow casing is formed by the holder portion 30 which can be engaged with the inside of the casing, and the winning ball sensor 40 is accommodated in the casing. The main body 20 is formed in a gate shape to form a passage path for the winning balls on the game board G, and game ball passing holes are formed at the top and bottom. The winning ball sensor 40 is formed in a strip plate shape and has a circular through hole through which a game ball can pass, and an electric coil is formed around this through hole to form an electromagnetic coil. Therefore, when the game ball passes, the energizing current in this electromagnetic coil changes, and the game ball can be detected. A lead wire 41 is led out to give an energizing current to the electromagnetic coil, and a connector 42 is also attached to the other end. A flange portion 21 is formed on the main body portion 20 so as to be in close contact with the surface of the game board G, and the flange portion 2 is formed.
1, screw-fastened through holes 22, 22 are formed.

The holder portion 30 has wedge-shaped convex portions 31 and 31 formed at the front end thereof, and the convex portions 31 and 31 are inserted into the concave portions 23 and 23 formed in the main body portion 20, whereby the main body portion is It is possible to engage with 20 together. On the other hand, the holder portion 30 itself has a substantially rectangular tube shape,
Since the winning ball sensor 40 may fall out rearward as it is, the pressing arm 3 having the convex portion 32a in the inner circumferential direction.
2 is extended rearward along the wall surface of the cylinder. This allows
The convex portion 32a of the pressing arm 32 engages with the rear end of the winning ball sensor 40, and the winning ball sensor 40 does not fall off.

The process up to this point is the same as that of the conventional winning ball detector 1, but the winning ball detector 10 of the present embodiment further has elastic temporary fixing pieces 50, 50 formed on the holder portion 30 described above. There is. The elastic temporary fixing pieces 50, 50 are provided with arm portions 51, 51 extending backward from the upper edge and the lower edge of the rear end of the holder portion 30 while extending slightly outward, and at the tip portions thereof. Is formed with wedge-shaped engaging portions 52, 52 that are tapered toward the front. Here, since the engaging portion 52 has a wedge shape, the arm portion 5
At the connection portion with 1, the step portion 52a is formed on the outside. The lengths of the arm portions 51, 51 are formed so that the distance from the step portion 52a to the flange portion 21 of the main body portion 20 substantially matches the thickness of the game board G.

Next, the operation of this embodiment having the above configuration will be described. First, as shown in FIG. 2, the winning ball detector 1
Assemble 0. That is, the holder portion 30 is brought close to the back surface side of the main body portion 20, and the convex portions 31, 31 on both sides of the tip end are inserted into the concave portions 23, 23 from the inside to be engaged. After that, the pressing arm 32 is bent outward so that the protrusion 3
The winning ball sensor 40 is housed in the hollow cylindrical portion without the interference of 2a. When the winning ball sensor 40 is completely housed, the pressing arm 32 is returned, so that the convex ball 3 is restored by itself.
2a engages with the rear end of the winning ball sensor 40. As described above, the assembling of the winning ball detector 10 is completed.

The winning ball detector 10 thus assembled is attached to the attachment hole H formed in the game board G by the robot arm R as shown in FIG. The robot arm R holds the main body portion 20 of the winning ball detector 10 by pinching it from above, inserts the lead wire 41 into the mounting hole H by another auxiliary tool (not shown), and then mounts the holder portion 30 side on the mounting hole H side. To insert. As shown in FIG. 4, the distance between the tips of the elastic temporary fixing pieces 50, 50 is slightly smaller than the opening diameter of the mounting hole H, and the robot arm R moves the winning ball detector 10 toward the mounting hole H. When pushed in, the elastic temporary fixing pieces 50, 50 are inserted so as to be pushed inward a little. This state represents the forced insertion state.

In this way, the flange portion 21 is a game board G
When it is inserted until it abuts on the surface of the
The tip of 2 will protrude to the back of the game board G,
When the stepped portions 52a, 52a reach the opening edge of the mounting hole H, the engaging portions 52, 52 are restored by the restoring force of the arm portions 51, 51.
Is pushed outward, and the stepped portions 52a, 52a engage with the opening edge of the mounting hole H. This state is shown in FIG.
As a result, the winning ball detector 10 is temporarily fixed to the game board G, and the robot arm R separates from the winning ball detector 10. In the conventional case, if the lead wire 41 hits something on the back side of the game board at this time, the winning ball detector 10 itself floats up due to the reaction force, but as described above, the elastic temporary fixing piece 50. It doesn't happen because it's temporarily stopped by. Then, after that, a robot arm (not shown) for screwing is brought into close proximity, and a screw is passed through the screwing through hole 22 and screwed into the game board G, and the winning ball detector 10 is permanently fixed.

In the present embodiment, an example in which two arm-shaped elastic temporary fixing pieces 50, 50 are provided is shown, but it is not always necessary to have such arm-shaped. 6 and 7 show another embodiment. In this example, the elastic temporary fixing piece 150 is composed of a tubular portion 151 having a diameter slightly smaller than that of the tubular portion 151 that can be inserted into the mounting hole H, and a plurality of pleats 152 formed outward from the peripheral surface thereof. The pleats 152 are preferably made of a vinyl material, and when the tubular portion 151 is inserted into the mounting hole H as shown in FIG.
Is pressed into a narrow gap with the mounting hole H, so that the winning ball detector 110 itself can be temporarily fixed.

Further, FIGS. 8 and 9 show another embodiment. In this example, while forming a U-shaped cut in the metal piece, the locking tool 251 is formed by bending and bending the tongue piece on the inner side, and the recess 252a to which the locking tool 251 can be mounted is temporarily fixed to the arm shape. It is formed on the piece 252. The temporary fixing piece 252 extends vertically from the flange portion 221 toward the mounting hole H.
1 is a mounting hole H that is sandwiched between the mounting hole H and the temporary fixing piece 252.
It will be locked to the peripheral surface of and will be prevented from coming off.

Further, in the above-mentioned embodiment, the present invention is applied as a winning ball detector, but is generally applied if it is an electrical accessory and is generally liable to be lifted by the lead wire. It is possible. 10 and 11 show an example applied as a wind turbine, which includes a light bulb 341 and a substrate 342 housed in the mounting hole H and is rotatable on the flange portion 321 on the game board G side. A windmill 324 is supported. In this case as well, the elastic temporary fixing pieces 350, 350 are extended toward the inside of the mounting hole H and can be engaged in the same manner.

The elastic temporary fixing piece 50 is a mounting hole H for mounting an electrical accessory.
However, it is possible to use it more effectively than just temporarily fixing it. FIG. 12 shows an example in which the elastic temporary fixing piece 50 is used for alignment.
Mortar-shaped grooves H1 and H1 are formed on the peripheral surface of the mounting hole H, and the cross section of the elastic temporary fixing piece 50 is formed in a chevron shape.
It is assumed that if the apex of the elastic temporary fixing piece 50 has the apex coinciding with the apex of the groove H1, alignment can be performed. As shown in FIG. 12, even if these vertices are slightly deviated from each other, the elastic temporary fixing pieces 50, 50 try to push each other by their restoring force, and therefore the arrows in the figure match each other. Move in the direction. As a result, it is set in the predetermined position, and the alignment is completed.

Such alignment can be appropriately modified by forming a general uneven shape. For example, a concave portion may be formed on the side of the elastic temporary fixing piece 50 and a convex portion may be formed on the side of the mounting hole H. On the other hand, the game board G itself is usually formed of plywood, and the back surface is a thin plate G1 in the sense that it forms a decorative surface.
Is attached. This thin plate G1 is generally used as a decorative surface, but in a game machine, it is often used for assembling various parts and for positioning for mounting the game board G itself to the game machine. That is, the thin plate G1 is partially cut off for engaging the concave and convex portions, and the mounting component is combined and positioned with respect to the concave and convex portions.

FIG. 13 shows an embodiment in which the thin plate G1 is cut out at the peripheral edge of the mounting hole H to form a recess J, which is engaged with the recess J cut out as shown in FIG. Positioning can be performed by fitting the portion 52.
In this way, the winning ball sensor 4 from which the lead wire 41 is derived
When the winning ball detector 10 accommodating 0 by the main body portion 20 and the holder portion 30 is permanently fixed to the mounting hole H of the game board G, elastic temporary fixing is performed from the rear end of the holder portion 30 toward the mounting hole H side. Since the pieces 50, 50 are extended and are temporarily pushed into the mounting hole H by engaging the engaging portion 52 with the opening edge, the robot arm R or the like automatically attaches the pieces. In such a case, it is possible to prevent the prize ball detector 10 itself from being lifted up by the lead wire 41 penetrating the mounting hole H and hindering the next screwing step.
