Description

  The present invention relates to a pachinko gaming machine, an arrangement ball gaming machine, a gaming machine such as a slot machine using a gaming ball as a gaming medium, and in particular, an opening / closing body such as a glass frame and a frame body such as a front frame can be opened and closed. The present invention relates to a hinge structure of a gaming machine that is connected to the machine.

  2. Description of the Related Art Conventionally, an opening / closing and detachable hinge structure has been used for an attachment structure of an opening / closing body and a frame body of a gaming machine for the purpose of maintenance and parts replacement. For example, a glass frame attached with a hinge structure on the front side of the front frame on which the game board is arranged, a multi-layer glass unit fitted with a hinge structure on the glass frame, and a ball tray unit attached with a hinge structure on the front side of the front frame And a ball tank unit or the like attached to the rear side of the mechanism plate with a hinge structure.

As such a hinge structure, for example, a glass frame (front frame) and a front frame are formed by a hinge including a hinge shaft (pivot), a support plate (bracket) that supports the hinge shaft, a spring, and a hinge hole. A hinge structure is known in which the doors are detachably connected (see, for example, Patent Document 1). The support plate is fixed to the glass frame, and the hinge hole is provided in the front frame. The hinge shaft knob (photograph) and the support plate are urged by the spring so that the hinge shaft protrudes. By moving the knob in the immersion direction against the urging force, the hinge hole is formed. The penetrating hinge shaft is immersed and the glass frame is removed.
JP 2001-161994 A

  However, in the above-mentioned hinge structure, the portion of the hinge shaft that protrudes from the hinge hole is forcibly pushed from above to be immersed, or the hinge hole is forcibly pulled up so that the hinge hole and the hinge shaft are separated to separate the glass frame. There was a problem that fraudulent acts to be removed were sometimes made. Further, the hinge shaft protrudes only by the biasing force of the spring, and when it is opened for maintenance, there is a possibility that the hinge shaft is unintentionally removed from the hinge hole.

  A similar hinge structure is known in addition to the above-described hinge structure that connects the glass frame and the main body frame, and there are similar problems.

  The present invention has been made in order to solve such a problem, and has a high crime prevention ability to prevent the hinge shaft from being removed from the hinge hole when the opening and closing body and the frame body are closed (strengthening countermeasures against illegal acts). ) Provide a hinge structure of a gaming machine.

The present invention is a hinge structure of a gaming machine that connects one side of an opening / closing body and one side of a frame body so as to be openable and detachable,
The hinge structure includes a hinge shaft, a support plate that supports the hinge shaft, and a hinge hole into which a head of the hinge shaft is fitted, and the support plate is provided on either the opening / closing body or the frame body. Is fixed, and the hinge hole is provided on the other side, and the frame body and the opening / closing body are attached and detached by allowing the head to protrude from the hinge hole,
The hinge shaft includes a protrusion on the head, and the protrusion prevents the head from fitting into the hinge hole, and the fitting position from which the head fits into the hinge hole. The opening / closing body and the frame body are in the non-fitting position when the opening / closing body and the frame body are at least closed.

  According to the present invention, when the opening / closing body and the frame are closed, the head of the hinge shaft does not fit into the hinge hole, so that the hinge shaft does not get into the hinge structure and is highly safe.

  The present invention relates to a hinge structure for a gaming machine that connects one side of an opening / closing body and one side of a frame so as to be openable / detachable. The frame body and the opening / closing body are not particularly limited as long as they are a combination of components that are preferably opened and closed and detachable in a gaming machine. For example, a front frame and a glass frame, a glass frame and a glass unit fitted into the glass frame, a ball tray unit including a front frame and a ball tray, a mechanism plate including a front frame and a substrate, a ball passage, and the like, a mechanism plate, A combination of a ball tank or the like for storing game balls. In particular, when the frame body is a front frame and the opening / closing body is a glass frame, the effect is more exhibited. These are connecting points where the hinge structure is easily visible from the front of the gaming machine, and a gaming board on which a plurality of winning devices are arranged is provided on the rear side of the glass frame. Because. Moreover, since it is a location that needs to be opened and closed most frequently in a gaming machine, a hinge structure that allows the worker to work more safely is required. In the present invention, the hinge structure is connected by at least one, preferably two or more hinges. It is more preferable to provide hinges in at least two places on the upper and lower sides of one side of the opening / closing body and the frame because the opening / closing movement becomes more stable.

  The hinge structure includes a hinge shaft, a support plate that supports the hinge shaft, and a hinge hole into which a head portion of the hinge shaft is fitted. The support plate is fixed to either the opening / closing body or the frame, and the hinge hole is provided to the other. The head of the hinge shaft, that is, the hinge hole side of the hinge shaft is projected and retracted from the hinge hole, so that the opening / closing body is detached from the frame. Further, the opening and closing body is configured to open and close from the frame body around the hinge shaft by penetrating the hinge shaft through the hinge hole in a protruding state. The hinge hole may be above or below the hinge shaft, but is provided above the hinge shaft when the hinge is higher than the operator's line of sight, and below the hinge shaft when the hinge is lower than the operator's line of sight. It is more preferable because it is easy to confirm the hinge hole and the operability is improved. The hinge shaft and the support plate may be provided on the opening / closing body or the frame body. However, if the hinge shaft and the support plate are provided on the opening / closing body, the hinge shaft is more preferable because the hinge shaft hardly obstructs the work when the opening / closing body is attached.

  The support plate is not particularly limited as long as it supports the base portion of the hinge shaft so as to be slidable in the axial direction. The support plate may be, for example, a U-shaped support plate including upper and lower holes through which the hinge shaft passes. Moreover, even if the hinge shaft is supported so as to be pivotable with respect to the support plate, it may be supported so as not to be pivotable. In addition, the base part of a hinge axis | shaft is a part which makes | forms the axis | shaft connected to the head part of the hinge axis | shaft which protrudes and retracts in a hinge hole. If the base section of the hinge shaft is substantially circular, it is more preferable because the shaft rotates smoothly.

  The hinge shaft includes a protrusion on the head, and the protrusion prevents the head from fitting into the hinge hole, and the fitting position from which the head fits into the hinge hole. It is characterized by being in the non-fitting position when the opening / closing body and the frame body are at least closed. When the opening and closing body and the frame are closed, even if the head of the hinge shaft is pushed in the immersive direction or the hinge hole is forcibly separated, the head of the hinge shaft protruding from the hinge hole is immersed. Therefore, the opening / closing body is not illegally removed. Further, when the opening / closing body and the frame body are opened at least at a predetermined angle, the hinge shaft can be positioned at the fitting position, whereby the hinge shaft can be slid to be inserted into the hinge hole. Since it becomes possible, the opening and closing body is removed from the frame. The opening angle between the opening / closing body and the frame body serving as the fitting position may vary or may be fixed, but the angle is 45 to 135 degrees, preferably within the range of 80 to 100 degrees. If it fixes so that it may become, since workability | operativity of opening-and-closing body attachment / detachment improves, it is more preferable. In addition, the angle used as a fitting position is determined by the shape of a hinge hole etc., for example.

  The head portion of the hinge shaft may have a larger or smaller shaft radius than the base portion of the hinge shaft, or may have a shape different from the shaft cross section of the base portion. The protrusion disposed on the head of the hinge shaft may be a part protruding from the outer edge (outer edge excluding the protrusion of the head) when the hinge shaft is viewed from the axial direction. That is, as long as the protrusion protrudes at least in the direction perpendicular to the hinge axis, the shape and size are not particularly limited. If the projection is provided below the tip of the hinge shaft, the head may be pivotally supported after the tip is pivoted regardless of the angle of the opening / closing body, etc., so that the head is fitted into the hinge hole. Workability can be improved. It is more preferable that the protrusion is provided at the tip of the hinge shaft because the head protruding from the hinge hole is shortened and the hinge structure can be made compact. The shorter the hinge shaft that protrudes in the axial direction from the hinge hole, the narrower the gap, so that it becomes difficult to perform the above-mentioned fraudulent acts, leading to suppression of the fraudulent acts. Moreover, since the range of a fitting position will become small if the said protrusion is a thin rod shape, the attachment / detachment position of an opening-closing body can be limited more, and safety | security becomes high.

  The hinge hole is not particularly limited as long as the opening portion is on the extension line of the hinge shaft and the head portion and the base portion of the hinge shaft can pass through, but it is preferable that the hinge hole includes a notch groove shaped like the protrusion. If such a notch groove is included, the range in which the hinge shaft becomes the fitting position is more limited. Therefore, when the opening / closing body is released from the frame body, it is difficult for the operator to unintentionally enter the non-fitting position. Become. The hinge hole only needs to be provided in one of the opening / closing body and the frame, but it is preferable that the hinge hole is provided in the frame because the workability is improved.

  The material of the parts constituting these hinge structures is not particularly limited. For example, a metal is preferable because it has high strength and can support a heavy opening / closing body. In particular, aluminum is more preferable because it has high strength and is relatively light. In addition, since a resin can be reduced in weight and cheaper than a metal, it is suitable for connection of a light opening / closing body. From the viewpoint of crime prevention, it is preferable to use a thermosetting resin (for example, phenol resin) that is relatively resistant to heat or a heat-resistant thermoplastic resin (for example, general-purpose engineering resin such as polycarbonate).

  In the present invention, the hinge structure preferably includes means for restricting the pivoting of the hinge shaft within the range of the non-fitting position when the opening / closing body and the frame body are closed. As a means for restricting the pivoting of the hinge shaft at the time of closing, for example, a protrusion that stops the pivoting of the hinge shaft due to the protruding projection of the hinge shaft may be provided in the vicinity of the hinge hole. More preferably, it further includes a hinge shaft fixing means for fixing the shaft rotation of the hinge shaft. The hinge shaft fixing means may fix the shaft rotation of the hinge shaft at least when the hinge shaft is closed. Since the hinge shaft is fixed so that the shaft does not rotate at the time of closing, even if the hinge shaft is supported by the support plate so as to be able to rotate the shaft, the hinge shaft is accidentally rotated. It can prevent becoming a fitting position. As the hinge shaft fixing means, for example, a lock provided on the side of the hinge hole for fixing the head of the hinge shaft at the non-fitting position, or a support plate, for fixing the base of the hinge shaft at the non-fitting position. Lock etc.

  In the present invention, the rotation of the hinge shaft is more preferably configured to follow the opening / closing of the opening / closing body (claim 3). In this configuration, since the opening / closing body is not opened to a predetermined angle with respect to the frame body, the fitting position is not reached. The safety is improved.

  In the present invention, it is preferable that the hinge structure further includes a hinge shaft immersion restricting means for restricting the immersion of the head portion of the hinge shaft described above when the opening / closing body and the frame body are closed. If the hinge shaft immersion restricting means is included, even if the hinge shaft is pivotable to the support plate, the hinge shaft and the hinge hole are erroneously disengaged at the time of closing and the opening / closing body is detached. There is no. As the hinge shaft immersion restriction means, for example, means for restricting the axial movement of the hinge shaft can be used. As a means for restricting the axial movement of the hinge shaft, specifically, an opening / closing body or a frame body on the hinge hole side is supported with respect to the hinge shaft so as to support a base portion of the hinge shaft in a protruding direction when the hinge shaft is closed. A substantially vertical protrusion or a recess into which a part of the base portion of the hinge shaft is fitted may be provided. More preferably, the hinge shaft immersion restricting means is a hinge shaft urging means for urging the hinge shaft against the support plate so as to keep the head protruding from the hinge hole. Since the hinge shaft is biased in the protruding direction even at the time of closing, the head of the hinge shaft does not immerse unless the operator applies a force that opposes the biasing direction of the hinge shaft biasing means. This is because workability is improved because it is easy to fit into the hinge hole when mounting. Examples of the hinge shaft urging means include a tension spring that is hooked between the base portion of the hinge shaft and the support plate, and a coil spring that is passed through the base portion of the hinge shaft.

  In the present invention, it is more preferable that the hinge shaft includes a knob on the opposite side to the head. The knob is not particularly limited in shape or size as long as it does not hinder the movement of the hinge shaft in the axial direction described above. For example, a knob is provided in a direction perpendicular to the hinge axis to form a knob. The end on the opposite side of the hinge shaft may be shaped like a hook to form a knob. It is more preferable if the end of the hinge shaft opposite to the head portion is bent into a substantially L shape to form a knob, since complicated molding is not required and no separate member is required. Further, it can also be used as the above-described hinge shaft immersion restricting means and the hinge shaft fixing means for restricting the rotation range of the hinge shaft.

  In the present invention, it is more preferable to provide notification means for notifying an operator when the hinge shaft is in the fitting position. As a notification means, for example, a step or taper is provided on the outer edge portion of the hinge hole that fits with the projection of the hinge shaft, and when the projection of the hinge shaft comes to the fitting position, a notice is given to the operator by clicking. Or providing a photo sensor that knows the fitting position in the hinge hole to notify the operator.

  In the hinge structure of the gaming machine of the present invention, the hinge shaft has a substantially circular axial cross section, and is L-shaped with one end side of the head and the other end side of the knob, and the head has a cross section Is a flat shape longer than the shaft cross section, the hinge hole includes a notch groove through which the head can pass, and includes a biasing spring as a hinge shaft biasing means, and the hinge shaft fixing means as the hinge shaft fixing means. What is necessary is just to make it the structure further including the guide wall arrange | positioned so that an axis rotation may not be performed along a hinge axis | shaft. In this hinge structure, the knob portion is fixed so that the hinge shaft does not rotate by contacting the guide wall, and the shaft rotation of the hinge shaft follows the opening / closing movement of the opening / closing body.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a front view showing an example of the hinge structure of the gaming machine of the present invention. As shown in FIG. 1, the gaming machine 1 includes a front frame 3 in which a game board 31, a lower ball tray 32 and a handle 33 are arranged on the front surface, a glass frame 2 fitted with a glass unit 21, and an upper ball tray 71. An upper ball tray unit 7 and an outer frame (not shown) arranged outside the front frame 3 are provided. The glass frame 2 is pivotally supported on the front left side of the front frame 3 by the upper hinge 4 and the middle hinge 5, and can be opened and closed with respect to the front frame 3. The upper ball tray unit 7 disposed under the glass frame 2 is pivotally supported on the front left side of the front frame 3 by the middle hinge 5 and the lower hinge 6, and can be opened and closed with respect to the front frame 3. It has become. Further, when the glass frame 2 and the upper ball tray unit 7 are closed with respect to the front frame 3, the front frame 3 is locked by the locking device 34.

  First, a hinge structure that connects the glass frame 2 and the front frame 3 so as to be openable and detachable will be described with reference to FIGS. FIG. 2 is an exploded perspective view of the upper left portion of the gaming machine 1 showing the upper hinge 4. FIG. 3 is a cross-sectional view of the upper hinge 4 as viewed from the front right side by cutting the game machine back and forth so as to pass through the hinge axis center of the upper hinge 4 in a state where the glass frame 2 and the front frame 3 are closed. . As shown in FIG. 1, the middle hinge 5 is opposed to a hinge hole 53 formed so as to sink into the lower left side of the front side of the glass frame 2 and the lower end of the glass frame 2 on the front left side of the front frame 3. And a hinge shaft 51 fixed to the support plate 52 so as to protrude upward. As shown in FIGS. 2 and 3, the upper hinge 4 has a hinge shaft 41 formed at the upper left corner of the front left side of the glass frame 2 so as to move up and down, a support plate 42 that supports the hinge shaft 41, and And a sheet metal 44 having a hinge hole 43 formed at the upper left corner of the front left side of the front frame 3.

  In this hinge structure, the glass frame 2 is first lifted and the hinge shaft 51 is inserted into the hinge hole 53 to connect the lower end corner of the glass frame 2 and the support plate 52 of the front frame 3. Next, the upper end corner of the glass frame 2 is overlapped with the front frame 3, the hinge shaft 41 is moved upward from below and fitted into the hinge hole 43, and the glass frame 2 is attached to the front frame 3. At this time, the glass frame 2 is in an open state with respect to the front frame 3. Moreover, since the hinge holes 43 and 53 hold | maintain the hinge shafts 41 and 51 so that rotation is possible, the glass frame 2 can be opened and closed with respect to the front frame 3. FIG. When removing the glass frame 2 from the front frame 3, the hinge shaft 41 and the hinge hole 43 on the upper hinge 4 side are first removed, and the upper end corner of the glass frame 2 and the upper end corner of the front frame 3 are reversed. And the glass frame 2 is lifted to remove the hinge shaft 51 and the hinge hole 53 on the middle hinge 5 side.

  Next, the structure of the upper hinge 4 will be described in detail with reference to FIGS. 4 is a top view of the upper left portion of the gaming machine 1. FIG. 4A shows that the glass frame 2 and the front frame 3 are opened, and the glass frame can be removed from the front frame 3 (just before the removal) by the upper hinge 4. FIG. 4B shows a state in which the glass frame 2 and the front frame 3 are closed (a state in which a normal game is played), and a state in which the glass frame 2 cannot be removed from the front frame 3 by the upper hinge 4. Yes.

  As shown in FIGS. 2 and 3, the upper hinge 4 includes a hinge shaft 41, a support plate 42, a sheet metal 44 having a hinge hole 43, and a coil spring 45. The upper hinge 4 is a hinge in which a hinge shaft 41 supported by a support plate 42 fixed to the glass frame 2 so as to be movable up and down passes through a hinge hole 43 provided on the front frame 3 side.

  The hinge shaft 41 is a substantially L-shaped metal member formed by bending a rod-shaped member having a substantially circular cross section, and its long side is a base portion 412 in the axial direction, and an end portion of the base portion 412 is a head portion Reference numeral 411 denotes a knob 413 whose short side is substantially perpendicular to the axial direction. The base 412 is a cylinder having substantially the same cross-section, and can smoothly move up and down the hinge shaft 41 described above. Further, the base 412 has a length sufficient for sliding up and down the hinge shaft 41. The head 411 is provided with two columnar projections 414 made of metal, 180 degrees apart, both substantially perpendicular to the axial direction of the hinge shaft 41. The protrusions 414 are fixed by penetrating a cylindrical rod through a through hole provided in the head portion 411 substantially perpendicular to the axial direction so that both ends protrude into protrusions 414.

  The support plate 42 is a sheet metal including a substantially U-shape, and a hole through which the base portion 412 of the hinge shaft 41 passes is provided in two substantially parallel upper and lower surfaces, and is slidable in the axial direction. The base portion 412 of the hinge shaft 41 is supported so that the shaft can rotate. The support plate 42 has a surface connecting the two surfaces and the glass frame 2 fixed with screws. Since the support plate 42 supports the base portion 412 at two locations, the upper and lower portions, the axial direction of the hinge shaft 41 is constant, and can be slid up and down stably. Further, as shown in FIG. 3, the hinge shaft 41 is disposed so as to be surrounded by the support plate 42 between the glass frame 2 and the surface connecting the two surfaces, so that the coil spring 45 is not damaged. Can be prevented.

  The coil spring 45 is wound around a portion disposed between two substantially parallel surfaces of the support plate 42 of the base 412. The upper end of the coil spring 45 is fixed by an E-ring, and the lower end is disposed on the lower surface of two substantially parallel surfaces of the support plate 42 described above, whereby the hinge shaft 41 is directed upward in the axial direction with respect to the support plate 42. Is energized.

  The sheet metal 44 has a flat plate shape and is fixed to the upper surface of the front frame 3 with screws. A hinge hole 43 is provided at the front end portion of the sheet metal 44 on the front side of the gaming machine 1. The hinge hole 43 has a shape in which a notch groove 431 in the shape of a protrusion 414 is formed in a through hole through which the base portion 412 can pass and an opening portion is substantially circular. The notch groove 431 is edged with a taper.

  The guide wall 46 is two plate-like members erected from a resin frame constituting the glass frame 2. The guide wall 46 is disposed below the portion of the support plate 42 that supports the hinge shaft 41 so that the base 412 is sandwiched between the two members. The length of the guide wall 46 is long enough that the lower end (the knob 413) of the hinge shaft 41 does not come out even when the hinge shaft 41 is moved up and down. By providing the guide wall 46, the hinge shaft 41 does not pivot with respect to the glass frame 2, but follows the opening and closing movement of the glass frame.

  As shown in FIG. 4A, the upper hinge 4 is opened when the glass frame 2 is opened and the shape of the head 411 of the hinge shaft 41 matches the shape of the hinge hole 43 (fitting position). Can be slid downward in the axial direction to remove the glass frame 2 from the front frame 3. Since the hinge shaft 41 is always urged by the coil spring 45 so as to protrude with respect to the support plate 42 and the hinge hole 43, even if the operator does not lower the knob 413 downward in the axial direction, Even so, the head 411 does not immerse from the hinge hole 43. Moreover, since the notch groove 431 is edged with a taper, it is guided when the projection 414 comes near the notch groove 431.

  Further, as shown in FIG. 4A, the hinge shaft 41 is in the fitting position when the glass frame 2 is opened at a predetermined angle, in this embodiment, approximately 90 degrees. This is because the hinge hole 43 is shaped as seen from above the head 411 of the hinge shaft 41. Further, this is because the hinge shaft 41 is fixed by the guide wall 46 so as to follow and rotate to open and close the glass frame 2. Therefore, even if the glass frame 3 is opened and the knob 413 is lowered by mistake during an operation such as maintenance, for example, the head 411 can maintain the protruding state as long as the angle is not the predetermined angle, so that the safety is high. The predetermined angle is not particularly limited to 90 degrees.

  As shown in FIG. 4B, when the glass frame 2 and the front frame 3 are closed and the positions of the protrusions 414 and the notch grooves 431 do not match (the non-fitting position), the upper hinge 4 The frame 3 is pivotally attached, and even if the head 411 is pushed in the immersive direction, even if the hinge hole 43 is forcibly pulled up, the head 411 protruding from the hinge hole 43 does not immerse. 2 will not be removed illegally. 4B shows a state in which the glass frame 2 and the front frame 3 are closed. However, the fitting position shown in FIG. 4A and the opening angle of the glass frame 2 must be a predetermined angle (about 90 degrees). For example, the same applies even if the glass frame 2 is open. The reason why the glass frame 2 is not removed unless the angle is the predetermined angle is that the hinge shaft 41 described above is driven by the guide wall 46 to open and close the glass frame 2.

  In the hinge structure of the present embodiment, the support plate 42 of the upper hinge 4 and the sheet metal in which the hinge hole 53 of the middle hinge 5 is formed can be a single member. The dimensional accuracy of the hinge structure of the glass frame 2 can be improved, and the glass frame 2 can be reinforced.

  In the hinge structure of this embodiment, the hinge shaft 41 provided with two protrusions on the head is used. However, it is also possible to use a hinge shaft having any one protrusion as shown in FIG. An axis can also be used. The hinge shaft 81 shown in FIG. 5A is the same as the hinge shaft 41 except that the protrusion 814 is provided at the tip of the head 811 and the length of the head 811 protruding from the hinge hole is shortened. The shorter the head portion of the hinge shaft that protrudes in the axial direction from the hinge hole, the shorter the length of the hinge structure and the more difficult it is to perform fraud. The hinge shaft 91 shown in FIG. 5B has an axial radius of the head portion 911 smaller than the base portion 912, and a circumscribed circle of the head portion 911 including the protrusion 914 when the hinge shaft 91 is viewed from the axial direction is smaller than the base portion 912. It is the same as the hinge shaft 81 except that it is made smaller. The hinge shaft 91 may be manufactured more easily than the hinge shaft 41 or the hinge shaft 81 because the head 911 and the protrusion 914 may be formed by grinding the tip of a rod-like member used for forming the hinge shaft 41, for example. When the hinge shaft 91 is used, the shape of the hinge hole is smaller than that of the hinge hole 43 and may be a shape that follows the head 911 including the protrusion 914.

  The hinge structure of this embodiment can also be applied to a hinge structure that connects the upper ball tray unit 7 and the front frame 3 so as to be openable and detachable. In the lower hinge 6 (see FIG. 1), a structure in which the axial direction of the upper hinge 4 is reversed, that is, a hinge hole provided in the front frame 3 is provided below the base of the hinge shaft provided in the upper ball tray unit 7. The arranged structure may be used.
