Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge mechanism for a game machine door for rotatably connecting a game machine door to a game machine body.

[0002]

2. Description of the Related Art FIGS. 6 and 7 show a conventional hinge mechanism for a game machine door (see Japanese Patent Application Laid-Open No. 6-292758).

In this hinge mechanism 112, a metal flat plate 116 mounted on a frame 114 of a machine body (game machine body) is provided.
A long link 122 and a short link 124 are pivotally connected between the flat metal fitting 120 installed on the door 118. FIG.
As shown in FIG. 7, when the door 118 is opened to the machine main body, the opening position is located in front of the machine main body (downward in FIG. 7), so that it does not become an obstacle when the door of the adjacent machine main body is opened. It has become.

In the hinge mechanism 112, a projection 126 protrudes from the upper surface of the flat bracket 120. Protrusion 1
As shown in FIG. 7, reference numeral 26 denotes a position where the door 118 comes into contact with the side surface of the long link 122 when the door 118 is opened by 90 degrees, thereby restricting the rotation angle of the door 118.

As described above, in the conventional hinge mechanism 112, the number of components is increased because the separate member such as the projection 126 is provided in order to limit the rotation angle of the door 118 within a certain range. In addition, the manufacturing process of the hinge mechanism 112 is complicated, which may lead to an increase in manufacturing cost.

[0006]

In view of this fact, the present invention can be manufactured at low cost without complicating the manufacturing process, and ensures that the range of rotation of the game machine door with respect to the game machine main body is within a certain range. It is an object of the present invention to obtain a hinge mechanism for a game machine door that can be restricted to the following.

[0007]

According to the first aspect of the present invention, there is provided a hinge mechanism for a game machine door for rotatably connecting a game machine door to a game machine body, the game machine body and the game machine door. And a link member for moving the center of rotation in a direction away from the main body of the game machine by a turning operation of the game machine door from the closed position to the open position, and the link. And a contact portion that abuts at least when the game machine door is at the closed position or the open position to limit the rotation of the game machine door.

That is, in the hinge mechanism of the amusement machine door (hereinafter, abbreviated to "hinge mechanism" as appropriate), a plurality of links constituting a link member are bridged between the amusement machine body and the amusement machine door. The amusement machine door is rotatably connected to the amusement machine main body by the link.

A link member composed of a plurality of links is
By rotating the game machine door from the closed position to the open position, the center of rotation of the game machine door is moved in a direction away from the game machine body. Thus, the amusement machine door is moved away from the amusement machine body by the opening operation (so as to protrude toward the user), so that the amusement machine door is prevented from contacting, for example, an adjacent amusement machine body at the time of opening. Therefore, it is possible to install the game machines with a shorter interval between the game machines.

[0010] Each of the plurality of links has a contact portion. Each contact portion abuts at least when the game machine door is in the closed position or the open position to limit the rotation of the game machine door. Thus, the game machine door is securely fixed at the closed position or the open position. Also, since the abutment portion is provided on the link itself to fix the game machine door at the closed position or the open position, a separate member such as a conventional projection is used to fix the game machine door at a predetermined position. There is no need to provide. Therefore, the number of parts constituting the hinge mechanism is reduced. The manufacturing process of the hinge mechanism is simplified, and the hinge mechanism can be configured at low cost.

According to a second aspect of the present invention, in the first aspect of the present invention, a main body side housing attached to the game machine main body and supporting the plurality of links respectively with the plurality of links, At least one of the links and the main body side housing are in contact with each other when the game machine door is in the open position and the closed position to provide resistance to the rotation of the game machine door and to rotate the game machine door. A contact member that is pressed by the operation and elastically retracts from the rotation region of the link.

That is, in the first aspect of the present invention, each of the plurality of links may be pivotally supported by the main body of the game machine. A main body side housing may be supported, and the main body side housing may be attached to the game machine main body so that the plurality of links are pivotally supported by the game machine main body via the main body side housing. With this configuration, each of the links can be pivotally supported by the main body of the game machine simply by attaching the main body side housing on which the plurality of links are pivotally supported to the main body of the game machine. Installation becomes easy.

A contact member is formed on at least one of the plurality of links and the main body side housing. The contact member comes into contact when the amusement machine door is at the open position and the closed position, and acts as a resistance to the rotation of the amusement machine door. For this reason, the amusement machine door is prevented from being accidentally rotated from the open position and the closed position. Further, the contact member is pressed by the turning operation of the amusement machine door, and is elastically retracted from the turning region of the link. For this reason, the rotation of the game machine door is not restricted. When the game machine door reaches the open position or the closed position, the contact member is configured to elastically restore to the rotation region of the link,
It is also possible to generate an appropriate click feeling in the rotation operation of the amusement machine door, and to perform the rotation operation more reliably.

According to a third aspect of the present invention, in the second aspect of the present invention, the contact member includes a projection formed on at least one of the links, and a projection formed by turning the link. A stopper attached to the main body side housing so as to be at least partially located within the movement area, and a stopper capable of being elastically retracted from the movement area.

Accordingly, the convex portion also moves with the rotation of the link, but at least a part of the stopper is located in this moving region. For this reason, the convex portion comes into contact with the stopper, and resistance is generated in the rotation of the link. Since the stopper can be elastically retracted from the moving area of the convex portion, the stopper is pushed by the convex portion and retracts, and the link can rotate. After passing through the convex portion, the stopper elastically recovers, and is located again in the moving region of the convex portion.

As described above, the contact member can be configured with a simple configuration in which the projection is provided on the arm and the stopper is attached to the housing on the main body side.

According to a fourth aspect of the present invention, in the third aspect of the present invention, there is provided a temporary fixing member provided on the stopper, the temporary fixing member being capable of temporarily fixing the stopper to the main body side housing. And

Since the stopper can be temporarily fixed to the housing on the main body side by the temporary fixing member, the manufacture of the hinge mechanism is facilitated.

According to a fifth aspect of the present invention, in the first aspect of the present invention, the first housing is arranged along a turning direction of the game machine door. A wall portion, a second wall portion integrally and parallel to the first wall portion, a first mounting plate portion extending from the first wall portion and fixed to the game machine main body, A second mounting plate portion extending from the second wall portion and fixed to the game machine main body; and a direction in which the first mounting plate portion extends from the first wall portion and the second mounting plate portion. The direction in which the mounting plate portion extends from the second wall portion is the same direction.

Therefore, for example, a plurality of links can be arranged between the first wall and the second wall. Further, the main body side housing can be securely mounted to the game machine main body by the first mounting plate portion and the second mounting plate portion.

Moreover, the direction in which the first mounting plate extends from the first wall and the direction in which the second mounting plate extends from the second wall are the same. Therefore, the main body side housing can be mounted on the main body of the amusement machine in a narrower mounting space than when the extending directions are reversed.

[0022]

FIG. 1 shows a game machine 14 to which a hinge mechanism 12 according to one embodiment of the present invention is applied. 2, 4 and 5 show the hinge mechanism 12 in an enlarged manner.

As can be seen from FIG. 1, the hinge mechanism 12
Is disposed between the game machine main body 16 of the game machine 14 and the game machine door 18, and the game machine door 18 is rotatably connected to the game machine body 16. Although FIG. 1 shows a case where two hinge mechanisms 12 are applied, the number of hinge mechanisms 12 is not limited to this, and may be, for example, three or more.

As shown in detail in FIG.
Has a body side housing 22 attached to the side wall 20 of the game machine body 16 and a door side housing 24 attached to the game machine door 18.

The main housing 22 is integrally formed by an upper wall plate 26 and a lower wall plate 28 which are formed in a substantially triangular shape in plan view, and a connecting plate 30 for connecting these. The upper wall plate 26 and the lower wall plate 28 are parallel to each other,
When the main body side housing 22 is viewed in the direction of arrow A in FIG. 2 and FIG.

From the lower wall plate 28, a lower mounting plate 32 that contacts the side wall 20 of the game machine main body 16 in a state of being attached to the game machine main body 16 extends. The lower mounting plate 32 is a lower wall plate 2.
8 is formed so as to be bent downward at a right angle, and a bolt hole 36 is formed at the center thereof. Further, from the upper wall plate 26, an upper mounting plate 34 that contacts the side wall 20 of the game machine main body 16 in a state of being attached to the game machine main body 16 extends. The upper mounting plate 34 also includes the upper wall plate 26.
And the lower mounting plate 32 and the upper mounting plate 34 are located in the same plane. Bolt holes 38 are also formed near the extended ends of the upper mounting plate 34. As shown in FIGS. 4 and 5, bolts 40 are inserted into these bolt holes 36, 38 and further screwed into the side wall 20. By doing so, the main body side housing 22 is attached to the game machine main body 16.

Since the upper mounting plate 34 and the lower mounting plate 32 extend in the same direction (downward in this embodiment) as described above, the upper mounting plate 34 and the lower mounting plate 32 are extended.
As a result, the space required for attaching the main body side housing 22 to the game machine main body 16 can be reduced. In addition, since the upper mounting plate 34 and the lower mounting plate 32 are close to each other, a load acting near the boundary between the lower wall plate 28 and the lower mounting plate 32 is reduced. The bending rigidity as a whole with the lower mounting plate 32 is high.

The auxiliary mounting plate 42 extends from the connecting plate 30 in the same manner. The auxiliary mounting plate 42 is also located in a plane formed by the upper mounting plate 32 and the lower mounting plate 34. A bolt hole 44 is also formed at the center of the auxiliary mounting plate 43, and the bolt 40 inserted into the bolt hole 44 is formed.
Is screwed to the side wall 20.

On the other hand, in the door side housing 24, the upper wall plate 44 and the lower wall plate 46 are connected by a connecting plate 48,
The whole is formed in a substantially “U” shape.

The main housing 22 and the door housing 2
The first link 50 and the second link 52 are bridged between the first link 50 and the second link 4. As shown in FIGS. 4 and 5, both the first link 50 and the second link 52 have one end 50A,
52A is pivotally supported on the main body side housing 22 by a pin 54, and the other end 50B, 52B is pivotally supported on the door side housing 24 by a pin 56.

The pins 56 protrude further upward from the upper wall plate 44 of the door-side housing 24.
Insertion hole 60 formed in bracket 58 of amusement machine door 18
Is inserted through. Thereby, the game machine door 18 is supported by the hinge mechanism 12. The upward movement of the game machine door 18 (disengagement from the pin 56) is prevented by a blocking means (not shown), so that the game machine door 18 is not accidentally detached from the game machine body 16. .

One end 52A of the second link 52 is pivotally supported at a position farther from the side wall 20 than one end 50A of the first link 50. Then, the game machine door 18 is connected to the game machine body 16.
Is rotated from the closed position (see FIG. 4) to the open position (see FIG. 5) in the direction of arrow R with respect to the first link 50 and the second link 52. The other ends 50B and 52B are both displaced in a direction away from the side wall 20 (downward in FIGS. 4 and 5). As a result, the amusement machine door 18 gradually protrudes toward the front side of the amusement machine 12 with the rotation from the closed position to the open position. , And can be opened sufficiently large.

The first link 50 is formed with a contact portion 62 which is narrower from a substantially central position in the longitudinal direction to the other end 50B. The second link 52 also has a contact portion 64 formed by cutting the side facing the first link 50 from the substantially central position in the longitudinal direction to the other end 52B.

As can be seen from FIG. 4, when the amusement machine door 18 is in the closed position, the contact portion 62 of the first link 50 is
The other end 52 </ b> B of the link 52 abuts, and the rotation of the second link 52 in the closing direction (the direction opposite to the arrow R <b> 2) is prevented. This also prevents the game machine door 18 from rotating in the closing direction (the direction opposite to the arrow R).

Also, as can be seen from FIG.
8 is in the open position, the contact portion 64 of the second link 52
The other end 50 </ b> B of the first link 50 abuts on the first link 50.
0 is prevented from rotating in the opening direction (the direction of the arrow R1). As a result, the rotation of the game machine door 18 in the opening direction (the direction of arrow R) is also prevented, so that the game machine door 1
8 is fixed in the open position.

A protrusion 66 is formed from one end 52A of the second link 52 in a direction opposite to the other end 52B. Due to the rotation of the second link 52, the protrusion 66 is moved to one end 50.
It moves in an arc-shaped rotation area around A.

As shown also in FIG.
A stopper 68 is disposed on the inner surface of the second connection plate 30. A mounting hole 70 is formed at one end of the stopper 68, and a mounting screw 72 is inserted into the mounting hole 70, and the stopper 68 is mounted on the connecting plate 30 of the main housing 22. An opening 74 is formed in the connecting plate 30 at a position corresponding to the other end of the stopper 68.
Is elastically bent in a direction away from the second link 52.

At the other end of the stopper 68, a bent portion 76 is formed which is bent in a substantially triangular shape in a direction away from the connecting plate 30, and both sides of the bent portion 76 are inclined surfaces 78, 80.
It has been. The bent portion 76 is formed so as to be located within the rotation area of the convex portion 66 formed on the second link 52. When the game machine door 18 is at the closed position, the convex portion 66 is formed.
Contacts the inclined surface 78 (see FIG. 4), and is bent in relation to the convex portion 66 such that the convex portion 66 contacts the inclined surface 80 when the game machine door 18 is at the open position (see FIG. 5). The shape and position of the part 76 are determined.

From the approximate center of the stopper 68, the temporary fixing piece 8
2 are protruding. Correspondingly, a temporary fixing hole 84 is formed in the lower wall plate 28 of the main body side housing 22. Before attaching the stopper 68 to the main body side housing 22 with the attaching screw 72, the temporary fixing piece 82 is
4 so that the stopper 68 can be temporarily fastened to the main body side housing 22. Thereby, the stopper 68 can be temporarily attached to the main body side housing 22 by the attachment screw 72 with the attachment screw 72 temporarily, and the operation when the hinge mechanism 12 of the present embodiment is assembled (especially, the operation of tightening the attachment screw 72) is easy. become.

A contact plate 86 is provided upright from the edge of the temporary fixing hole 84. When the first link 50 rotates in the direction of arrow R1 as shown in FIG.
The portion near 0A is set to a position where it contacts the contact plate 86. This also prevents the rotation of the first link 50 in the direction of the arrow R1. The contact plate 86 may be formed by attaching a member formed separately from the main body side housing 22 to the main body side housing 22 in a later step. If it is formed so as to rise substantially at a right angle, the contact plate 86 can be provided by simple processing without increasing the number of parts.

Next, the operation of the hinge mechanism 12 of this embodiment will be described.

As shown in FIG. 4, when the amusement machine door 18 is in the closed position, the other end 52B of the second link 52 contacts the contact portion 62 of the first link 50, and the closing direction of the second link 52. Since rotation in the direction opposite to the arrow R2 is prevented, rotation of the game machine door 18 in the closing direction is also prevented. Further, in this state, the convex portion 66 is provided on the inclined surface 7 of the stopper 68.
8 and there is resistance in the rotation of the second link 52 in the opening direction, so that the game machine door 18 does not inadvertently rotate in the opening direction.

When the amusement machine door 18 is turned in the opening direction (the direction of the arrow R), at the initial stage of the turn, the convex portion 66 comes into contact with the inclined surface 78, which is a resistance to the turning of the second link 52. Therefore, an appropriate resistance (so-called click feeling) is generated also in the rotation of the amusement machine door 18, and the opening operation can be reliably performed.
When the game machine door 18 is rotated against this, the other end of the stopper 68 is bent because the convex portion 66 presses the inclined surface 78, and the bent portion 76 is retracted from the rotation region of the convex portion 66. As a result, the second link 52 becomes rotatable, so that the game machine door 18 can be turned in the opening direction.

When the convex portion 66 gets over the bent portion 76 by the rotation of the second link 52, the inclined surface 80 comes into contact with the convex portion 66. In this state, the elastic reaction force of the stopper 68 acts on the projection 66 to urge the second link 52 to rotate in the direction of the arrow R2, so that the game machine door 18 is also urged in the opening direction,
The game machine door 18 can be opened with a small force. The opening angle of the game machine door 18 (the angle from the closed position to the open position) is not particularly limited, but is about 1 in the present embodiment.
The angle is set to 00 ° so that the front of the game machine main body 16 is sufficiently opened.

As shown in FIG. 5, when the game machine door 18 reaches the open position, the other end 50B of the first link 50 contacts the contact portion 64 of the second link 52. Furthermore, the first link 50
The portion near one end 50 </ b> A also contacts the contact plate 86. Thus, the opening direction of the first link 50 (the direction of the arrow R1).
Is prevented from rotating. Rotation of the game machine door 18 in the opening direction (the direction of the arrow R) is also prevented. Also, in this state,
The convex portion 66 is in contact with the inclined surface 80 of the stopper 68,
Since resistance occurs in the rotation of the second link 52 in the closing direction, the amusement machine door 18 does not inadvertently rotate in the closing direction (the direction opposite to the arrow R).

The contact portion 64 of the second link 52 and the first
The first link 5 only contacts the other end 50B of the link 50.
If the rotation in the direction of arrow R1 can be reliably prevented, the contact plate 86 may not be provided.

When the amusement machine door 18 is rotated in the closing direction (the direction opposite to the arrow R), at the initial stage of the rotation, the convex portion 66 comes into contact with the inclined surface 80 and the resistance of the rotation of the second link 52 is reduced. Therefore, similarly to the case where the game machine door 18 is opened, an appropriate resistance (click feeling) is generated in the rotation of the game machine door 18, and the closing operation can be performed more reliably. When the amusement machine door 18 is turned against this, the other end side of the stopper 68 is bent because the convex portion 66 presses the inclined surface 80, and the bent portion 76 is retracted from the rotation region of the convex portion 66. As a result, the second link 52 is rotatable, so that the game machine door 18 can be rotated in the closing direction.

When the convex portion 66 gets over the bent portion 76 by the rotation of the second link 52, the inclined surface 78 comes into contact with the convex portion 66. In this state, the elastic reaction force of the stopper 68 acts on the convex portion 66 to urge the second link 52 to rotate in the direction opposite to the arrow R2, so that the game machine door 18 is also urged in the closing direction. The game machine door 18 can be closed with a small force.

As can be seen from the above description, in the hinge mechanism 12 of the present embodiment, the game machine door 18 can be securely held at the predetermined positions (the closed position and the open position) without providing a separate member such as a conventional projection. And the number of parts constituting the hinge mechanism 12 is reduced. Also, the manufacturing process of the hinge mechanism 12 can be simplified, and the hinge mechanism 12 can be manufactured at low cost.

In the above description, the link member of the present invention has been described as an example having two links (the first link 50 and the second link 52). The number of links constituting the link mechanism is not limited as long as the center of rotation moves forward from the game machine main body 16 by the rotation of the game machine door 18 in the opening direction. For example, the link mechanism of the present invention may be composed of three or more links.

The links need not necessarily be supported by the game machine main body 16 and the game machine door 18 via the main body side housing 22 and the door side housing 24. 18 may be directly supported by the shaft. When the main body side housing 22 and the door side housing 24 are provided as in the present embodiment, the first link 50 and the second link 52 are respectively connected to the main body side housing 2.
If the hinge mechanism 12 is assembled to the door 2 and the door-side housing 24, the hinge mechanism 12 is attached to the game machine main body 16 and the door-side housing 24. 16 to be rotatable. As compared with the case where each link is separately attached to the game machine main body 16 and the game machine door 18, the number of attachment steps is reduced, so that the work becomes easy.

[0052]

Since the present invention has the above-mentioned structure, it can be manufactured at low cost without complicating the manufacturing process, and the rotation range of the amusement machine door with respect to the amusement machine body can be reliably limited to a certain range.
