[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening preventing member, and more particularly to a front plate of a game machine.
The present invention relates to a door opening preventing member for preventing the front plate from being completely opened when the front plate is opened.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a general game machine has a box-shaped frame 10 and a front plate 20 of the frame 10. . This front plate 20
As shown in FIG. 4, in consideration of the convenience of assembly and maintenance, it is fixed to a frame via a so-called hinge 30 and is formed to be openable and closable with respect to the frame 10. Here, in a general gaming machine, the rotation axis of the hinge 30 is vertical.

The hinge 30 is composed of, for example, two plate portions having one end rounded and a bar, and the rounded portions of the two plate portions are alternately missing, and the rounded portion is formed. And by inserting a bar, the two plate portions are formed so as to be able to rotate with respect to each other. The longitudinal direction of the bar of the hinge 30 becomes vertical, and one of the plate portions is fixed to the frame 10 and the other is fixed to the front plate 20, so that the front plate 20 can be freely opened and closed with respect to the frame 10. Will be formed.

A key 19 is provided between the front plate 20 and the frame 10.
In general, the closed state is maintained.

[0005]

However, the above-mentioned conventional means for forming the front plate 20 so as to be openable and closable with respect to the frame 10 by the hinge 30 has the following problems. First, the front panel 20 incorporates a large number of devices and members called front panel units, such as operation buttons and a medal tray, necessary for the progress of the game of the gaming machine, and is very heavy. Therefore, if the front plate 20 is opened and opened immediately to the opening limit, an excessive load is applied to the hinge 30 by an impact generated when the opening limit is reached, and the hinge 3
0 is destroyed, hinge 30 and front plate 20 or frame 10
There was a situation where cracks were formed at the joints with the joints.

Secondly, in many cases, beside the gaming machine, a medal lending machine for lending a medal serving as a game medium of another gaming machine or the gaming machine is installed adjacent to the gaming machine. Therefore, when the front board 20 is opened and suddenly opened to the opening limit, the opened front board 20 may hit an adjacent gaming machine or a medal lending machine, or a player or a medal lending machine playing a game at the adjacent gaming machine. There was a situation in which the user was in the way.

[0007] In order to solve the above problems,
It is necessary to provide a gaming machine having a configuration in which the front plate 20 is not completely opened immediately when the front plate 20 is opened, and the front plate 20 cannot be opened at a certain angle or more. Therefore, in order to prevent a player using a medal lending machine attached to a game machine or a player playing a game at an adjacent game machine from being disturbed, a structure for preventing the medal lending machine from opening at a certain angle, for example, 90 degrees or more, has been proposed. In some cases, a simple stopper is provided. However, since such a stopper cannot reduce the impact when the opening limit is reached, the impact generated when the opening limit is reached will place an excessive load on the stopper or the hinge 30, and the stopper or the hinge 30 There is a drawback that the situation in which 30 is destroyed cannot be prevented.

The problem to be solved by the present invention is that when opening the front board of a game machine, the impact is reduced by temporarily stopping the opening in the middle of the game machine, and at the same time, the front board is provided to a person beside the game machine. By providing a door opening preventing member that can be easily opened by 90 degrees or more when necessary, it is possible to prevent the above problematic situation from occurring. is there.

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and provides the inventions described in claims 1 to 3. That is, the invention described in claim 1 is
A door opening prevention member used for a game machine having a box-shaped frame and a front plate that can be opened and closed around a rotation axis with respect to the frame, wherein the door-opening prevention member is used for any one of the frame and the front plate. A trajectory forming plate that is pivotally supported on one side in parallel with the rotation axis of the front plate, and has a slot, an urging member that rotationally urges the trajectory forming plate, and is fixed to the other of the frame or the front plate, And, when the front plate is opened or closed with respect to the frame, the track forming plate is formed into the groove of the track forming plate by the urging member. The force plate is moved along the forcing member, and the pressing surface, which is the inner surface of the slot pressed against the forcing member when the track forming plate is urged by the forcing member, uses the forcing member to open the front plate. It is characterized in that an intermediate stop step portion for stopping is provided.

According to a second aspect of the present invention, the intermediate stop step portion of the door opening preventing member according to the first aspect is provided such that the intermediate stop step portion is provided on the pressing surface of the slot from the pressing surface of the slot to the non-opposite surface. It is characterized in that it is formed as a protruding piece protruding toward the pressing surface. Further, the invention according to claim 3 is characterized in that the intermediate stop step portion of the door opening prevention member according to claim 1 is configured such that the pressing surface of the slot has a non-pressing surface facing the pressing surface from the pressing surface of the slot. It is characterized in that it is formed as a cutout recess cutout in the opposite direction.

[0011]

According to the gaming machine using the door opening prevention member of the invention of the first aspect, the following operations are achieved before the front plate is opened. When opening the front plate closed with respect to the frame, the track forming plate is rotationally urged by the urging member and moves while pressing the forcing member against the pressing surface of the groove of the track forming plate. .

The track forming plate moves to a position where the intermediate stop step of the slot of the track forming plate reaches the forcing member. Then, the track forming plate stops while the intermediate stop step portion contacts the forcing member. That is, the front plate that was being opened stops halfway and is in a half-open state. Since the track forming plate is rotationally urged by the urging member, it is pressed while applying a pressing surface to the forcing member, and if no force is applied from the outside, the intermediate stop step portion hits the forcing member. As it is, the track forming plate maintains the stopped state, so that the front plate is maintained in the half-open state.

The kinetic energy of the front plate, which is generated when the front plate is half-opened relative to the frame, is absorbed by the collision between the intermediate stop step of the track forming plate and the forcing member. Almost no burden is placed on etc. If you want to do a little maintenance, it is enough to use this half-open state. To further open the front plate that has been stopped in the half-open state, first, a force in a direction opposite to the rotational bias is applied to the track forming plate by some means. Then, since the intermediate stop step is released from the forcing member, the track forming plate becomes movable, and the front plate can be further opened.

[0014] The kinetic energy stored in the front plate when moving from the intermediate stop step position to the opening limit is smaller than suddenly opening to the opening limit, and a large load is not applied to hinges and the like. Since the track forming plate is urged by the urging means, the front plate is kept open.

According to the game machine using the door opening prevention member of the invention, the forcing member collides with the intermediate stop step portion protruding inside the slot, and the front plate is framed. Is maintained in a half-open state. Further, according to the gaming machine using the door opening prevention member of the invention according to claim 3, the front plate is half-opened with respect to the frame by the forcing member being fitted into the notched recess formed inside the slot. It is maintained in a state.

[0016]

The present invention will be described in more detail with reference to the following examples. The following embodiments correspond to the first or second aspect of the present invention. First, the configuration of the present embodiment will be described with reference to FIG. The door opening preventing member of the present embodiment is used by being fixed to a frame 10 of a gaming machine and a front plate 20 which is pivotally supported on the frame 10 via a hinge 30 as a “rotating shaft”. is there. The gaming machine of this embodiment is
Like a general game machine, the rotation axis of the hinge 30 is vertical.

The door opening preventing member according to the present embodiment includes a rotation fixing plate 40 which is bent in an L shape and fixed to a corner of the front plate 20;
A forcing plate 60 which is bent into an L shape having substantially the same shape as the rotation fixing plate 40 and is fixed to a corner of the frame 10, and an axial center screw 41 perpendicular to the end of the horizontal portion of the rotation fixing plate 40. And a trajectory forming plate 50 that is rotatably supported by the actuator and is forced to rotate by the forcing plate 60.

The rotation fixing plate 40 has two through-holes in its L-shaped vertical portion, and is fixed to a corner of the front plate 20 by screws adapted to the through-holes. A through hole is also provided near the tip of the L-shaped horizontal portion, and the track forming plate 50 is rotatably fixed via a central screw 41 around which a coil spring 49 as an urging member is wound. Track forming plate 50
Is a substantially rectangular plate having a central screw 41 at one end thereof.
Of the track forming plate 50 is increased by slightly bending the end portion on the side located outside the gaming machine in the longitudinal direction, in order to penetrate the track forming plate 50. The center portion of the track forming plate 50 has a slot 51 punched in a crank shape. In the slot 51, the track forming plate 50 is urged by the coil spring 49 in the direction of the hinge 30, which is the plane counterclockwise direction. Here, the anti-hinge 30 on the inner surface of this slot 51
The side is referred to as a pressing surface 51A, and the inner surface facing the pressing surface 51A is referred to as a non-pressing surface 51B.

Regarding the angle of the crank portion of the slot 51, the side opposite to the hinge 30 forms a substantially right angle, and the side of the hinge 30 forms an obtuse angle. In the following description, a right angle crank portion provided on the pressing surface 51A side of the slot 51 is an open crank portion 52 as an intermediate stop step portion, and an obtuse angle crank portion provided on the non-pressing surface 51 side is a closed crank portion. 53, the end on the side of the central screw 41 is referred to as a closed end 55, and the end on the side opposite to the central screw 41 is referred to as an open end 54.

The forcing plate 60 has two through-holes in the L-shaped vertical portion, similarly to the rotation fixing plate 40, and is fixed to a corner of the frame 10 by screws that fit into the through-holes. Further, a through hole is also provided near the tip of the L-shaped horizontal portion, and a forcible screw 61 as a forcing member for forcing the rotation path of the track forming plate 50 by fitting into the slot 51 of the track forming plate 50 is provided. Fix it.

When the forcing screw 61 is located at the open end 54 of the slot 51, the rotation fixing plate 40 and the forcing plate 60
Make an angle of approximately 90 degrees. The coil spring 49 urges the track forming plate 50 toward the hinge 30 so as to press the forcible screw 61 against the pressing surface 51A of the slot 51. Hereinafter, the operation of the present embodiment will be described.

First, a description will be given of a state from a state where the front plate 20 is closed to the frame body 10 to a state where the front plate 20 is opened to the opening limit. When the front plate 20 is closed with respect to the frame 10, the rotation fixing plate 40 and the forcing plate 60 are arranged in parallel, and the forcible screws 61 of the forcing plate 60 engage with the slot 51 of the track forming plate 50.
Is located at the closed end 55. That is, the track forming plate 50
Has an open end 54 side protruding into the frame 10. The front plate 20 is kept closed by a key 19 and the like interposed between the front plate 20 and the frame 10.

When the key 19 is unlocked and the front plate 20 starts to be released from the frame 10, the track forming plate 50 presses the forcible screw 61 against the pressing surface 51A of the inner surface of the slot 51 while the track forming plate 50 is pressed. From the closed end 55 of the slot 51 to the open end 54 along the slot 51, and eventually the position of the forcible screw 61 of the slot 51 moves to the open crank 52.
Here, the open crank part 52 of the slot 51 is
When the collision occurs, the pressing surface 51A on which the open crank portion 52 is provided is pressed by the coil spring 49 against the forcible screw 61.
1 is maintained. Thereby, the front plate 20 is in a half-open state. Even if the front plate 20 is to be further opened, since the coil spring 49 urges the track forming plate 50, the pressing surface 51A of the inner wall of the slot 51 is pressed against the forcible screw 61. As a result, the front plate 20 is maintained in the half-open state.

The kinetic energy of the front plate 20, which is generated when the front plate 20 is half-opened with respect to the frame 10, is absorbed by the collision between the open crank portion 52 and the forcible screw 61, and the hinge 30 Almost no burden is placed on etc. If you want to do a little maintenance, it is enough to use this half-open state. In order to open the front plate 20 from this half-open state to the open limit, the forcible screw 61 is moved by hand by moving the track forming plate 50 in the direction opposite to the biasing direction of the coil spring 49 so that the open crank portion 5 is opened.
Track forming plate 5 stopped by staying at 2
0 is released from the compulsory screw 61. Then, the track forming plate 50 moves until the position of the forcible screw 61 reaches from the open crank portion 52 to the open end portion 54. The front plate 20 thus opened with respect to the frame 10 forms an angle of about 90 degrees. Since the moving distance of the front plate 20 at this time is not so long, the kinetic energy stored by the front plate 20 when moving this distance is not so large, and the slot 51
Is absorbed by the collision between the open end 54 of the first screw and the forcible screw 61. Therefore, a large load is not applied to the hinge 30 and the like.

The track forming plate 50 is urged counterclockwise by the coil spring 49, so that the pressing surface 51 A of the open end 54 of the slot 51 is pressed against the forcible screw 61. Therefore, the front plate 2 which has reached the opening limit
0 is the force screw 61 even if it is going to the closed state.
The open end 54 is stopped. For this reason,
It stops in a state where it is opened to the rotation fixing plate 40 and the forcible plate 60 open limit.

To move the front plate 20 from the open limit to the closed state, the front plate 20 is rotated about the hinge 30 in the closing direction. Then, the forcible screw 61 is pressed against the pressing surface 5 of the slot 51.
The track forming plate 50 moves while being pressed by 1A. At this time, if the front plate 20 is slowly closed,
When the open crank reaches the forced screw 61, the track forming plate 50 largely rotates counterclockwise by the urging force of the coil spring 49. Conversely, if the front plate 20 is rapidly closed, the forced screw 61 reaches the obtuse closed crank portion 53 even if the forced screw 61 is faster than the rotation of the track forming plate 50 when the forced screw 61 reaches the open crank portion 52. Therefore, the track forming plate 50 moves smoothly by the closed crank portion 53.

According to the door opening preventing member of this embodiment, it is possible to provide a door opening preventing member that can absorb an impact when the front plate 20 is opened and can also maintain the open state. There is an effect that. Hereinafter, variations of the present embodiment will be described. In the above-described embodiment, the pressing surface 5 of the slot 51 is used as the intermediate stop step.
The open crank portion 52 provided in 1A has been described. However, this intermediate stop step is provided by the coil spring 49.
It is sufficient that the opening of the track forming plate 50 that is rotationally biased by the force screw 61 is stopped when the front plate 20 is opened. Therefore, the intermediate stop step may be formed in the shape of the slot 51 of the track forming plate 50 as shown in FIGS. 2 and 3.

According to the trajectory forming plate 50 thus formed, the movement of the trajectory forming plate 50 can be stopped by the forcible screw 61 colliding with the protruding piece 52A.
The operation is substantially the same as that of the above-described embodiment, and the same effect can be obtained. Subsequently, the track forming plate shown in FIG. 3 will be described. In addition, if the track forming plate described below is used, it corresponds to the invention described in claim 1 or 3.

The track forming plate 50 is a substantially rectangular plate material, and has a through hole 59 at one end thereof for allowing the central screw 41 to pass therethrough. A substantially rectangular slot 51 is punched out of the center of the track forming plate 50. In the slot 51, the inner surface pressed against the forcible screw by the bias of the track forming plate 50 by the coil spring 49 is referred to as a pressing surface 51A, and the inner surface facing the pressing surface 51A is referred to as a non-pressing surface 51B. . In the pressing surface 51A, a notched concave portion 52B which is formed from the pressing surface 51A in a direction opposite to the non-pressing surface 51B is formed.
