Description

  The present invention relates to a gaming machine in which a second frame is supported by a first frame so as to be freely opened and closed via a hinge mechanism.

  Generally, a gaming machine is provided with a hinge mechanism at one end in the width direction of the outer frame, and the hinge mechanism can freely open and close a front frame that holds a glass plate, an inner frame that holds a game board, and the like. Is pivotally supported. The hinge mechanism is normally provided at the upper end and the lower end in the vertical direction of the outer frame, but due to the characteristics of the gaming machine, there is a possibility that a game ball may enter the hinge mechanism provided at the lower end. If the front or middle frame is closed with a game ball invading on the hinge mechanism, the game ball will be sandwiched between the front or middle frame and the outer frame, and the front or middle frame can be closed. Otherwise, there is a risk that each frame may be damaged due to the pinching of game balls.

  Therefore, in the gaming machine disclosed in Patent Document 1, a game ball hole is formed in the hinge mechanism provided at the lower end so that the game ball does not stay on the hinge mechanism.

As shown in the figure, the gaming machine main body 1 has an outer frame 2 in which an enclosed space is formed by four sides assembled in a substantially rectangular shape, and, similarly to the outer frame 2, an enclosed space is formed by four sides assembled in a substantially rectangular shape. The middle frame 4 in which the game board 3 is held and the front frame 6 in which the transmission plate 5 made of glass or resin is held are provided in the surrounding space.

  A hinge mechanism 7 is provided on the upper side at one end in the width direction of the outer frame 2, and a hinge mechanism 10 is provided vertically below the hinge mechanism 7. The middle frame 4 and the front frame 6 are pivotally supported on the outer frame 2 by the hinge mechanisms 7 and 10 so that the middle frame 4 and the front frame 6 are closed with respect to the outer frame 2. The frames 2, 4, 6 are parallel, and the game board 3 and the transmission plate 5 face each other in parallel while maintaining a predetermined distance.

  The middle frame 4 has a shorter circumference than the outer frame 2 and the front frame 6. When the middle frame 4 and the front frame 6 are closed with respect to the outer frame 2, the middle frame 4 is the outer frame 2 and the front frame 6. Since it is accommodated in the frame 6, it has a dimensional relationship in which the middle frame 4 cannot be visually recognized from the outside. Further, the middle frame 4 and the front frame 6 can be opened and closed independently with respect to the outer frame 2.

  In the following, the structure of the hinge mechanism 10 will be described. Here, the case where the front frame 6 is pivotably supported by the hinge mechanism 10 provided on the middle frame 4 will be described, and the outer frame 2 will be described. Is omitted. Therefore, in this embodiment, the middle frame 4 corresponds to the first frame of the present invention, and the front frame 6 corresponds to the second frame of the present invention. However, the front frame 6 may be pivotally supported by the outer frame 2 by the following configuration, or the middle frame 4 may be pivotally supported by the hinge mechanism 10 fixed to the outer frame 2. In any case, the hinge mechanism 10 is interposed between the first frame body and the second frame body that are relatively opened and closed, and the application is not limited by the type of the frame body or the like.

  FIG. 2 is a conceptual diagram for explaining the hinge mechanism 10 of the present embodiment. In the present embodiment, the hinge mechanism 10 is provided on the left side 4a located on the left side in the front view of the gaming machine main body 1 in the middle frame 4 having four sides. In the following drawings, the left side of the gaming machine body 1 on which the hinge mechanism 10 is provided is described as L, and the right side of the gaming machine body 1 that is the free end side of the front frame 6 is described as R.

Left 4a of the middle frame 4, as well as to protrude the left end surface 4a ₁ on the front side of the gaming machine main body 1, from the left end surface 4a ₁ at a position a predetermined distance apart in the R direction, the protruding piece 4b of the gaming machine main body 1 It protrudes to the front side. The hinge mechanism 10 is arranged between the left end surface 4a ₁ of the inner frame 4 and the projection piece 4b.

  The hinge mechanism 10 includes a first main body portion 11 made of a metal flat plate member fixed to the left side 4 a of the middle frame 4. In the first main body 11, the angle formed between the flat surface portion 11a and the left side 4a of the middle frame 4 is maintained at a right angle, and the left side 4a of the middle frame 4 is positioned with the flat surface portion 11a positioned vertically upward. Is fixed so as to protrude from the front side of the gaming machine main body 1.

  The hinge mechanism 10 includes a second main body 12 formed by bending a metal flat plate member at a right angle. The second main body portion 12 includes a flat surface portion 12a superimposed on the flat surface portion 11a of the first main body portion 11, and a fixed surface 12b that bends 90 degrees vertically from one end surface of the flat surface portion 12a. doing. The flat surface portion 12a of the second main body portion 12 is formed to have a smaller area than the flat surface portion 11a of the first main body portion 11, and the flat surface is formed by the rotary shaft portion 13 penetrating both the flat surface portions 11a and 12a in the vertical direction. It is rotatably supported by the part 11a. The fixing surface 12 b is fixed to the front frame 6, more specifically, to the back surface of the reinforcing metal plate 8 fixed to the front frame 6. As a result, the front frame 6 rotates about the rotation shaft portion 13 as a rotation axis, and the front frame 6 is opened and closed with respect to the middle frame 4 by this rotation.

The reinforcing sheet metal 8 includes an end portion 8a that is bent at a right angle on the back side of the gaming machine main body 1. The protruding piece 8b is disposed at a predetermined distance in the R direction from the end portion 8a. The fixing surface 12b is fixed between the end 8a and the protruding piece 8b. At this time, the end portion 8a, rather than the left end surface 4a ₁ of the middle frame 4 is located slightly R direction, the rear projecting portion 8a ₁ located on the rear side distal end of the gaming machine main body 1 at the ends 8a but it is positioned on the rear side than the front end portion of the left end surface 4a ₁ of the middle frame 4. The back protrusion 8a ₁ has a curved shape with a radius of curvature that is a straight line connecting the rotary shaft 13 and the back protrusion 8a ₁ .

In addition, as shown in FIG. 2, when the front frame 6 is closed with respect to the middle frame 4, the middle frame 4 and the front frame 6 are parallel to each other. An intrusion prevention member 20 is provided in the facing interval formed between the first main body 11 and vertically above. The intrusion prevention member 20 has a width that can be accommodated between the left end face 4a ₁ and the protruding piece 4b, and when the front frame 6 is closed with respect to the middle frame 4, the left side of the middle frame 4 It is comprised in the thickness which can be accommodated between 4a and the sheet metal 8 for reinforcement. Further, the intrusion prevention member 20 includes a curved surface 20a in which a surface located on the front side of the gaming machine main body 1, in other words, a surface facing the back surface of the reinforcing sheet metal 8 is curved. The curved surface 20a is configured such that the height in the vertical direction is approximately the same as the diameter of the game ball so that the game ball dropped on the flat surface portion 11a does not enter the intrusion prevention member 20.

Further, the curved surface 20a is a curved shape that is convex from the front side to the back side of the gaming machine body 1, more specifically, a straight line connecting the curved surface 20a and the rotary shaft portion 13 is a radius of curvature (rotation axis). When the reinforcing sheet metal 8 is rotated about the rotating shaft 13, the rear protrusion 8 a ₁ and the curved surface 20 a are configured to smoothly move relative to each other. That is, the curved surface 20a has a curvature along the movement locus of the end portion 8a of the front frame 6 (reinforcing sheet metal 8).

  A rocking shaft 21 is fixed in the vicinity of the L-side end of the intrusion prevention member 20, and the rocking shaft 21 is pivotally supported by a rocking support piece 22 fixed to the left side 4a. Yes. Further, an urging member 23 made of a leaf spring is provided between the back surface of the curved surface 20a of the intrusion prevention member 20 and the front surface of the left side 4a. The urging member 23 exerts an urging force in a direction in which the left side 4a and the intrusion prevention member 20 are separated from each other, in other words, in a direction in which the intrusion prevention member 20 is urged toward the front side of the gaming machine main body 1. .

However, the reinforcing sheet metal 8 is provided with a protruding piece 8 b that protrudes toward the intrusion prevention member 20. When the front frame 6 is closed with respect to the middle frame 4, the protruding piece 8 b prevents the intrusion. in contact with the contact edge 20a ₁ of the curved surface 20a of the member 20, the penetration preventing member 20 is held in position shown. Further, a swing restricting portion 24 that protrudes toward the projecting piece 4 b is provided at the R-side end of the intrusion prevention member 20, and a gaming machine is provided on the projecting piece 4 b with respect to the swing restricting portion 24. A locking portion 4b ₁ facing the front side of the main body 1 is provided.

In a state where the front frame 6 (reinforcing metal plate 8) is opened by a predetermined amount or more with respect to the middle frame 4, the swinging shaft portion 21 is used as an axis so as to follow the opening operation of the front frame 6 (reinforcing metal plate 8). Although permeation prevention member 20 is rotated, this time, rotation of the intrusion preventing member 20, swing restriction portion 24 is restricted by contact with the locking portion 4b _1. That is, the swing restricting portion 24 and the locking portion 4b ₁ function as a stopper that restricts the swing range of the intrusion prevention member 20.

  Next, the operation of the hinge mechanism 10 having the above configuration will be described in detail with reference to FIGS. 3 and 4. FIG. 3 is a diagram for explaining the operation until the opening angle of the front frame 6 with respect to the middle frame 4 becomes a predetermined angle. FIG. 4 shows that the opening angle of the front frame 6 with respect to the middle frame 4 becomes a predetermined angle or more. It is a figure explaining the operation | movement in a case.

  When the front frame 6 is opened from the state in which the front frame 6 (reinforcing metal plate 8) is closed with respect to the middle frame 4, as shown in FIGS. 3 (a) and 3 (b), the rotating shaft portion 13 is moved. As a shaft, the second main body 12 rotates in the direction of the arrow x, and the reinforcing sheet metal 8 moves in the direction of the arrow y together with this rotation. Then, since the protruding piece 8b is integral with the reinforcing metal plate 8, the protruding piece 8b moves in a direction away from the curved surface 20a of the intrusion prevention member 20. Therefore, the intrusion prevention member 20 tries to move the free end side (R side end portion) to the front side of the gaming machine main body 1 by the biasing force of the biasing member 23. Since the end 8a contacts the curved surface 20a, the intrusion prevention member 20 is held in substantially the same posture as when the front frame 6 (the reinforcing metal plate 8) is closed.

Then, as shown in FIG. 3B, the opening angle of the front frame 6 with respect to the middle frame 4 becomes a predetermined angle, and the back protrusion 8a ₁ becomes the contact end 20a ₁ of the curved surface 20a of the intrusion prevention member 20. It is assumed that the front frame 6 is further opened with respect to the middle frame 4 in the contact state. Then, as shown in FIG. 4A, the urging force of the urging member 23 causes the end of the intrusion prevention member 20 on the R side to rotate about the swinging shaft portion 21, and the contact end of the curved surface 20a. The part 20a ₁ contacts the end 8a of the reinforcing sheet metal 8. In this state, when further opening the front frame 6 (reinforcing sheet metal 8), while the contact state between the contact end portion 20a ₁ and the end portion 8a is maintained, intrusion so as to follow the opening movement of the reinforcing sheet metal 8 The prevention member 20 rotates.

Then, as shown in FIG. 4 (b), prior to contact with the contact edge 20a ₁ and the end portion 8a is released, swing restriction portion 24 is engaged with the engaging portion 4b _1, intrusion prevention member Twenty or more rotations are restricted. In the present embodiment, the swing regulating portion 24 is to be restricted even more open at the same time as being engaged with the engaging portion 4b _1, the front frame 6 (reinforcing sheet metal 8) Therefore, the contact end 20a ₁ and the reinforcing sheet metal 8 are always kept in contact with each other.

  Thus, the urging force of the urging member 23 always acts in the direction of opening the front frame 6 (reinforcing metal plate 8) via the intrusion prevention member 20. That is, when the front frame 6 (reinforcing sheet metal 8) is opened, a force is provided against the direction in which the front frame 6 is closed, so even if the front frame 6 is closed momentarily, It will be equipped with a buffer function to reduce the momentum. Further, for example, the urging force of the urging member 23 also functions as a stopper that maintains the front frame 6 in a certain amount of open state.

  Therefore, when performing maintenance or the like, the operator can perform the operation without holding the front frame 6 by hand, and even if a force that closes the front frame 6 acts on some beat, There is a risk that the body may be pinched and injured, or the transmission plate 5 may be broken or various members of the gaming machine main body 1 may be damaged by the impact when the front frame 6 is closed to the middle frame 4 vigorously. Can be reduced.

  As shown in FIG. 5, when the front frame 6 is opened, the game ball falls on the flat surface portion 11a of the first main body portion 11, and the game ball stays on the flat surface portion 11a. Suppose that In this state, when the front frame 6 (reinforcing sheet metal 8) is closed with respect to the middle frame 4, the game ball is pushed along the curved surface 20a by the end 8a of the reinforcing sheet metal 8 in the z direction in the figure. Then, it falls vertically downward from the flat surface portion 11a. Thus, when the front frame 6 (reinforcing sheet metal 8) is closed with respect to the middle frame 4, a game ball is sandwiched between the middle frame 4 and the front frame 6 (reinforcing sheet metal 8), Reduces the possibility that the front frame 6 (reinforcing sheet metal 8) cannot be closed or that the middle frame 4 and the front frame 6 (reinforcing sheet metal 8) are damaged by the pinching of the game balls. be able to.

  That is, according to the intrusion prevention member 20 of the present embodiment, it is possible to prevent the game ball from being caught while having a simple configuration, and the front frame 6 is maintained in a certain open state, so that workability is improved. In addition, since the momentum in the closing direction is buffered, the risk of various members being damaged can be reduced.

  In the present embodiment, the case where the intrusion prevention member 20 swings following the front frame 6 (the reinforcing metal plate 8) has been described. However, the intrusion prevention member 20 does not necessarily have a swingable configuration. Good. As long as the intrusion prevention member 20 has at least the curved surface 20a along the movement locus of the end 8a of the reinforcing sheet metal 8, the gaming ball from above the flat surface portion 11a of the first main body portion 11 is used. Can be discharged.

However, as in the comparative example shown in FIG. 6A, when the intrusion prevention member 20 does not swing and is fixed to the flat surface portion 11a of the first main body portion 11, the reinforcing sheet metal 8 is opened. when the angle becomes a predetermined angle or more, the gap is formed between the contact end portion 20a ₁ and the end portion 8a, when closing the reinforcing sheet metal 8 with respect to the inner frame 4, the game ball into the gap There is a risk of being caught. In contrast, as shown in FIG. 6 (b), if it swings with a penetration preventing member 20 to the opening operation of the reinforcing sheet metal 8, the contact end 20a ₁ of the intrusion preventing member 20, since the end portion 8a of the reinforcing sheet metal 8 is always maintained in contact, the whole there is no possibility that the game ball is sandwiched, the catch prevention function of the game balls between the contact end portion 20a ₁ and the end portion 8a Can be further improved.

  Note that when the intrusion prevention member 20 is swung, the specific configuration for swinging the intrusion prevention member 20 is not particularly limited. In the present embodiment, the urging member 23 made of a leaf spring is provided between the left side 4a and the intrusion prevention member 20, but for example, it is made of a tension spring between the end portion 8a and the intrusion prevention member 20. An urging member may be interposed. Further, the reinforcing sheet metal 8 and the intrusion prevention member 20 are made to swing the intrusion prevention member 20 in the same manner as described above in accordance with the opening / closing operation of the reinforcing sheet metal 8 without applying an elastic force to the intrusion prevention member 20. It may be simply linked (connected).

  In the present embodiment, the case where the reinforcing sheet metal 8 is fixed to the front frame 6 has been described, but the reinforcing sheet metal 8 is not essential. Therefore, the front frame 6 and the intrusion prevention member 20 may be configured to be in direct contact with each other, or a member other than the reinforcing sheet metal 8 provided on the front frame 6 and the intrusion prevention member 20 are in contact with each other. You may do it.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Is done.
