Description

  The present invention relates to a hinge of a detachable type (hinge pin insertion type) that supports a door of a game machine or the like so as to be openable and closable with respect to a casing.

  Conventionally, for example, as a hinge that supports the door of a slot machine so that it can be opened and closed, it is composed of a fixed member and a movable member. There is known a detachable hinge having a structure that protrudes downward and is fixed, and the pin is inserted into a bearing hole on the fixing member side and assembled. This hinge is usually attached to two places, an upper part and a lower part between the main body and the front door, because the shape of the game machine is large.

  In order to smoothly open and close the door of the slot machine, it is necessary to attach the rotary shafts of the two hinges mounted between the main body and the front door so that the axial center positions thereof are accurately aligned. Therefore, when two hinges are attached between the main body and the front door as described above, the two fixing members are fixed to the main body side with the axial center position of the bearing portion aligned, and the corresponding positions on the front door side are fixed. The two movable members have to be fixed with their pin centers accurately aligned, making it difficult and cumbersome to attach the hinges, and requiring a lot of time and man-hours.

  Accordingly, the inventors of the present invention are hinges composed of a vertically long fixed member and a movable member, and bearing portions each having a bearing hole at the upper and lower edge portions of the mounting plate portion of the fixed member each have an axial center position. Each pin is provided on the winding plate formed on the upper and lower edges of the mounting plate portion of the movable member so as to coincide with each other on the axis, and each pin has a shaft center position on one axis and the lower side. He proposed a hinge that was fixed by protruding into the bearing, and both pins were assembled by inserting them into the bearings of the fixing member.

  This hinge is constructed by providing bearing holes that serve as bearings on the upper and lower parts of the vertically long fixed member on the same axis and attaching pins on the same axial line on the upper and lower parts of the same vertically long movable member. When assembling the hinge, the front door to which the movable member is attached is lifted and simultaneously inserted into the upper and lower bearing holes of the stationary member on the main body side. For this reason, even if it is the front door of a heavy game machine, a hinge, ie, a front door, can be assembled | attached by aligning the axis | shaft of an up-and-down pin comparatively easily.

  On the other hand, as a hinge of this type, conversely to the above, pins are attached to the upper and lower parts of the vertically long fixed member on the same axis, and bearing holes serving as bearing parts are provided on the same axial line to the upper and lower parts of the vertically long movable member. The hinge of the structure provided in is known by the said patent document 1.

  In this type of hinge, the upper and lower bearing holes and the upper and lower pins are located on the same axis line of each member. Therefore, it is relatively easy to move the upper and lower bearings while holding the movable member. The upper and lower pins of the fixed member can be easily fitted into the upper and lower bearing holes and the upper and lower pins, and after the movable member is fitted into the bearing hole, the movable member is fixed to the fixed member. However, it can rotate smoothly within a predetermined angle range.

  By the way, this type of detachable hinge is used on the housing side to attach the front door to the housing with many electrical components attached to the inside of the front door at the time of manufacture, like a game machine. The structure of the hinge-fixing member's pin is fitted into the hinge-moving member bearing part on the front door side so that it can be assembled easily. However, there is a problem that it is easily detached from the fixing member. For this reason, in the hinge proposed in Patent Document 2, a locking groove is provided on the outer periphery of the tip of the pin, and a C-ring (E-ring) is provided in the locking groove in a state where the bearing portion is fitted to the pin. The hinge movable member fitted and assembled is prevented from being detached from the hinge fixing member.

  However, for example, in a gaming machine such as a slot machine, there is a case where the front door is removed and electrical parts are adjusted or exchanged at the time of manufacture or in a hall. It is necessary to remove the member from the fixed member.

  However, since the structure in which the bearing portion of the movable member is easily removed from the pin of the fixed member is likely to cause a problem in terms of security of the game machine, it is necessary to have a structure in which the movable member cannot be attached and detached with the front door closed. However, when the front door is removed from the housing at the time of manufacture or the like for adjustment or replacement of electrical components, the movable member can be easily removed from the hinge fixing member with the front door open. A hinge was requested.

  The present invention has been made in view of the above points, and prevents the movable member from being detached during normal use, and allows the movable member to be easily removed from the fixed member with the door opened when parts replacement or adjustment is necessary. An object is to provide a detachable hinge that can be removed.

To achieve the above object, the hinge of the present invention is:
In a detachable hinge that is attached between the openable and closable door of the game machine and the housing, and has a vertically long first member and a second member,
A bearing member having a bearing portion is fixed to at least an upper portion and a lower portion in the base frame of the first member so that the axial center position of the bearing hole coincides with one axis, and the mounting plate portion of the second member A hinge pin that can be fitted into the bearing member is fixed to at least the upper and lower edges of the shaft so that the axial center position coincides with one axis,
A locking groove is formed in the outer peripheral portion near the tip of the hinge pin,
A slide member is slidably disposed in the bearing member,
In the vicinity of the bearing hole of the bearing member, a pin locking member having a locking portion for locking the hinge pin enters the locking portion of the hinge pin inserted into the bearing hole. And a biasing spring that biases the locking portion in a direction in which the locking portion is locked to the locking groove of the pin ji pin.
The slide member is provided with an inclined engaging portion that engages with the pin locking member, and a pressing tip is exposed from the bearing member,
When the slide member is slid by pushing the pressing tip, the inclined engaging portion engages with the pin locking member, and the locking portion is against the spring force of the biasing spring. The pin engaging member slides in a direction away from the locking groove of the hinge pin.

  In the hinge of the present invention, the first member is fixed to the door as a movable member and the second member is fixed to the casing of the game machine as a fixed member, or vice versa, the second member is fixed to the door as a movable member. The first member is fixed to the casing as a fixing member. Further, for example, when the first member of the hinge is fixed to the door as a movable member and the second member is fixed to the housing as the fixed member, the hinge pin provided on the second member is fixed upward. Conversely, when the second member of the hinge is fixed to the door as a movable member and the first member is fixed to the housing as a fixed member, the hinge pin provided on the second member is fixed downward.

  When the hinge is used with the first member fixed to the door as a movable member and the second member fixed to the housing as a fixed member, the bearing hole of the movable bearing member holding the door should be Align the bearing member with its axial position so that it is aligned with the hinge pin, align the axis of the bearing hole with the axis of the pin, and lower the position of the movable-side bearing member slightly in this state, and move the hinge pin on the fixed member side to the movable-side It is made to fit in the bearing hole of a bearing member. At this time, the locking portion of the pin locking member enters and locks into the locking groove of the hinge pin, and the hinge pin is locked to the bearing member and is prevented from being detached.

  With the door-side first member (movable member) open with respect to the housing-side second member (fixed member), if the slide member's pressing tip is pressed from the outside, the sliding member's inclined engaging portion is pinned. Acting on the locking member, the pin locking member slides against the spring force of the biasing spring, and the locking portion is detached from the locking groove of the pin ji pin. For this reason, if the door, that is, the first member (movable member) is moved so that the bearing member of the first member slides in the axial direction of the hinge pin of the second member, the first member (movable member) can be easily moved to the second member. It can be removed from the member (fixing member).

  Here, an end inclined portion is provided at the end of the slide member, and when the first member or the second member is rotated in the closing direction, the shaft holding portion of the hinge pin is engaged with the end inclined portion. Then, the slide member can be returned and slid, and the locking portion of the pin locking member can be locked with the locking groove of the hinge pin. According to this, if the hinge pin is fitted into the bearing member and the first member and the second member are rotated in the closing direction, the slide member automatically returns and slides, and the locking portion of the pin locking member is It is possible to engage with the locking groove of the hinge pin and automatically prevent the hinge pin from coming off.

  Further, here, the coil spring as the urging spring is held by a spring holding portion provided in the pin locking member, and an engagement recess is provided in the slide member adjacent to the inclined engagement portion of the slide member. When the slide member returns and slides and the spring holding portion of the pin locking member enters the engagement recess, the locking portion of the pin locking member locks with the locking groove of the hinge pin. It can be constituted as follows. The slide member may be provided so as to be slidable up and down in the bearing member, and the pressing tip portion of the slide member may be provided so as to protrude upward from the upper surface of the bearing member. According to this, in a state where the first member on the movable side is opened with respect to the second member, the pressing tip of the slide member is easily pushed to release the locking by the locking portion of the pin locking member, and the first member is It can be removed from the second member.

  According to the hinge of the present invention, the movable member is prevented from coming off during normal use, and in the open state, the movable member can be easily detached from the fixed member by pushing the pressing tip of the slide member in the open state when parts replacement or adjustment is necessary. be able to.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, this hinge is a vertically long hinge in which the movable member 1 as the first member and the fixed member 11 as the second member are detachably provided. As described above, for example, the movable member 1 is fixed to a door D of a game machine such as a slot machine, and the fixed member 11 is fixed to the inside of a casing C of the game machine. As shown in FIG. 4, the movable member 1 has a channel-shaped base frame body 2 formed by bending a vertically long steel plate into a substantially U-shaped cross section. The bearing member 3 having a bearing hole 3a in the vertical direction is fixed to the lower portion by a fixing screw 4 or rivet caulking.

  The base frame body 2 of the movable member 1 is formed into a long channel material shape having a substantially U-shaped cross section with an opening on the front side, and a bearing member is provided inside each of the upper portion, the middle portion, and the lower portion. 3 is fixed. The bearing member 3 is integrally formed in a substantially rectangular parallelepiped shape with a hard synthetic resin or the like, a recess 3d is formed in an intermediate portion, and a bearing hole 3a is formed downward in a horizontal plane portion 3b which is an upper surface of the recess 3d. A hinge pin 15 on the fixed member 11 side is fitted into the bearing hole 3a from below to constitute a bearing portion. In addition, the bearing member 3 may be provided on the same axis of two places, the upper part and the lower part of the movable member 1, or may be provided at four places.

  Further, as shown in FIG. 6, the lower portion of the bearing member 3 is configured to have a recess 3d, and a magnetic metal spring plate 9 is used as a ground plate in the middle position of the recess 3d. It is attached. In the case of a game machine of an electronic device such as a slot machine, it is necessary to electromagnetically shield the electronic device in the housing C. For this reason, the metal frame of the casing C and the metal frame of the door D are usually connected by a ground wire. In particular, when the bearing member 3 is formed of a synthetic resin as described above, the electrical connection between the hinge fixing member 11 and the movable member 1 is likely to fail.

  For this reason, as shown in FIGS. 5 and 6, the curved metal plate 9 reliably connects the fixed member 11 on the housing C side and the movable member 1 on the door D side to the recess 3 d position of the bearing member 3. It is attached so that it may connect. As shown in FIGS. 12 to 14, the metal plate 9 is a metal plate in which the metal shaft holding portion 13 of the fixed member 11 is bent with a spring property when the hinge fixed member 11 and the movable member 1 are assembled. 9, the inner side of the metal plate 9 contacts the inner side of the metal base frame 2 of the movable member 1, and the electrical connection between the fixed member 11 and the movable member 1 can be ensured.

  As shown in FIGS. 4 and 17, the base frame 2 of the movable member 1 has a U-shaped cross section, and its left side wall is wider than the right side wall. When used by attaching to the door D of the machine, the bearing member 3 and the shaft holding portion 13 are covered with the left side wall to prevent illegal acts such as inserting foreign objects through the gap between the casing C of the game machine and the door D. At the same time, the bending strength of the long base frame body 2 is increased. Further, when the door D is closed, the left side wall of the base frame 2 abuts on the edge of the mounting plate portion 12 of the fixing member 11 to close the gap between the housing C and the door D.

  Further, as shown in FIG. 2 and the like, a stopper portion 3c that can contact the lower surface of the shaft holding portion 13 or the hinge pin 15 protrudes from the lower portion of the bearing member 3, and the hinge pin 15 of the fixing member 11 is inserted into the bearing hole 3a. When the movable member 1 is assembled to the fixed member 11 and is rotated to the closed state, the hinge pin 15 or the lower surface of the shaft holding portion 13 comes into contact with the movable member 1 and the movable member 1 does not come off. It has a structure. Further, an annular locking groove 15a is provided on the outer periphery of the pin near the tip of the hinge pin 15. When the hinge pin 15 is inserted into the bearing hole 3a of the bearing member 3, the locking groove 15a enters the locking groove 15a so that the hinge pin 15 in the bearing hole 3a enters the locking groove 15a. And acts as a retaining stopper.

  Further, the positions of the bearing holes 3a of the three bearing portions are located in the vicinity of one wall portion of the base frame body 2 and the rear wall of the bearing member 3, and when a hinge pin 15 of the shaft holding portion 13 described later is fitted. These axial centers are arranged so as to coincide with each other. Such a bearing member 3 is fixed to fixed positions of the upper part, the middle part, and the lower part in the base frame body 2 with fixing screws 4 or rivets.

  As shown in FIGS. 5, 7, and 8, the bearing member 3 is slidably provided with a pin locking member 6 in order to prevent the hinge pin 15 inserted into the bearing hole 3 a from being detached. The pin locking member 6 includes a locking portion 6a locked in a locking groove 15a provided in the vicinity of the distal end portion of the hinge pin 15 and a spring holding portion 6b of a biasing spring 7 (coil spring). In the slit hole formed in the upper part of the bearing member 3, it accommodates so that sliding is possible in the front-back direction of FIG. The spring holding portion 6b of the pin locking member 6 is provided with a biasing spring (coil spring) 7, and the pin locking member 6 is attached so that the locking portion 6a of the pin locking member 6 protrudes forward. Be forced.

  Further, a slide member 8 is inserted into the bearing member 3 adjacent to the pin locking member 6 so as to be slidable in the vertical direction. The slide member 8 is operated so as to be pushed down from above when the movable member 1 is in an open state, and moves so that the pin locking member 6 that locks the hinge pin 15 moves to unlock the hinge pin 15. As shown in FIGS. 7 and 8, the slide member 8 is formed in a square bar shape, and a pressing tip 8 d is formed at the upper end portion, and can be exposed (projected) upward from the bearing member 3. Further, the lower end portion (end portion) of the slide member 8 is formed with an end inclined portion 8c having an inclined surface, and an engagement recess 8a is formed on the side surface above the end inclined portion 8c, and the engagement is made. An inclined engagement portion 8b is formed on the upper side in the recess 8a.

  The engaging recess 8 a is formed so that the spring holding portion 6 b of the pin locking member 6 can enter, and when the slide member 8 is in the upper position, the spring holding portion of the pin locking member 6 is applied by the biasing force of the biasing spring 7. 6b enters the engaging recess 8a, and at this time, the locking portion 6a of the pin locking member 6 engages with the locking groove 15a of the hinge pin 15 to prevent the hinge pin 15 from coming off. In addition, when the pressing tip 8d of the slide member 8 is pressed down, the inclined engaging portion 8b presses the spring holding portion 6b of the pin locking member 6, and the pin locking member 6 compresses the biasing spring 7. That is, the structure in which the bearing member 3 can be detached from the hinge pin 15 by sliding the latching portion 6a of the pin latching member 6 in the direction to remove from the latching groove 15a of the hinge pin 15 to release the retaining pin of the hinge pin 15. It has become.

  The slide member 8 is slidably inserted into the bearing member 3 with a certain degree of frictional resistance. As shown in FIG. 16B, the spring of the urging spring 7 when the pressing tip 8d is pushed down. The force is received in the lateral direction via the spring holding portion 6 b and is stopped by the frictional resistance in the bearing member 3. Further, the slide member 8 is lifted when the movable member 1 is closed and the distal inclined portion 8c receives a pushing force from the shaft holding portion 13 of the fixed member 11, and the hinge pin is locked as shown in FIG. It is the structure which returns to.

  That is, the end inclined portion 8c provided at the lower end of the slide member 8 is formed so as to protrude downward from the horizontal surface portion 3b in which the bearing hole 3a of the bearing member 3 is formed when the movable member 1 is in an open state. When the movable member 1 is closed, as shown in FIG. 16A, the end inclined portion 8 c receives a push-up force from the shaft holding portion 13 of the fixed member 11 and rises. At this time, the pin locking member 6 returns to the locking position, and the locking portion 6a enters the locking groove 15a of the hinge pin 15 to be in the hinge pin locked state.

  On the other hand, when releasing the retaining of the hinge pin 15 by the locking portion 6a of the pin locking member 6 and removing the bearing member 3 from the hinge pin 15, the slide member 8 is pushed down as shown in FIG. The spring holding portion 6b is pushed by the engaging portion 8b, and the locking portion 6a of the pin locking member 6 is slid so as to be disengaged from the locking groove 15a of the hinge pin 15. In this state, the locking portion 6a of the pin locking member 6 is disengaged from the locking groove 15a of the hinge pin 15, and the slide member 8 receives the spring force of the biasing spring 7 via the spring holding portion 6b. The slide member 8 maintains its unlocked state. Since the bearing member 3 of the movable member 1 is normally placed on the shaft holding portion 13 of the hinge pin 15 of the fixed member 11 as shown in FIG. When the movable member 1 is removed, the bearing member 3 is lifted up and removed.

  As described above, when the bearing member 3 of the movable member 1 is assembled to the fixed member 11, the bearing hole 3 a of the bearing member 3 of the movable member 1 is formed in the hinge pin of the fixed member 11 when the movable member 1 is opened. 15 is fitted from above. In a state before the bearing member 3 of the movable member 1 is fitted, the slide member 8 is pushed down as shown in FIG. 16B, and the end inclined portion 8c protrudes downward from the horizontal surface portion 3b. After fitting the bearing member 3, the movable member 1 is rotated in the closing direction with respect to the fixed member 11. At this time, the shaft holding portion 13 of the fixed member 11 is relatively rotated to tilt the end. The part 8c is pushed up. As a result, during normal use, the slide member 8 rises to the normal locking position as shown in FIG. 16A, and the pin locking member 6 engages the locking portion 6a with the locking groove 15a of the hinge pin 15. As a result, the hinge pin 15 has a structure that prevents the hinge pin 15 from coming off.

  On the other hand, as shown in FIGS. 9 to 11, the fixing member 11 includes a mounting plate portion 12 made of a vertically long and strip-shaped steel plate, and an L-shaped cross-sectional portion 12 a extending on a side portion of the mounting plate portion 12. Is attached to the upper portion, the middle portion, and the lower portion of the side portion of the L-shaped cross-sectional portion 12a. The shaft holding portion 13 that holds the hinge pin 15 is attached to each attachment piece 12b by a fixing screw 14. As shown in FIGS. 7 and 8, the hinge pin 15 is formed with a locking groove 15a in an annular shape on the outer periphery thereof, so that the locking portion 6a of the pin locking member 6 can enter the locking groove 15a. .

  Thereby, when the bearing hole 3a of the bearing member 3 of the movable member 1 is fitted so as to cover the hinge pin 15 of the fixed member 11, the latching portion of the pin latching member 6 is caused by the spring force of the biasing spring 7. 6a enters the locking groove 15a, locks the hinge pin 15, locks the bearing member 3 with respect to the hinge pin 15, and prevents the bearing member 3 from coming off from the hinge pin 15.

  Each shaft holding portion 13 is formed by molding a metal so that the hinge pin 15 protrudes and holds upward, and the shaft holding portion 13 is provided with an attachment hole, and is fixed to the attachment piece 12b as shown in FIG. Each shaft holding portion 13 is attached using a screw 14. At this time, each hinge pin 15 is attached with its axial center position aligned so that its axis passes on one axis along the longitudinal direction of the attachment plate portion 12. In addition, the shaft holding part 13 having the hinge pin 15 can be provided at two places only in the upper part and the lower part, or can be provided at four places.

  As shown in FIG. 15, the hinge configured as described above has a fixing member 11 inserted into the mounting hole of the mounting plate 12 inside the left side wall of the opening of the casing C of the game machine. The base frame body 2 is fastened and fixed to the position corresponding to the fixed member 11 inside the left end portion of the door D of the game machine by an attaching screw.

  Then, with the door D opened, the bearing holes 3a of the upper, middle, and lower bearing members 3 of the hinge movable member 1 are fitted to the upper, middle, and lower hinge pins 15 of the fixing member 11 of the housing C, and FIG. As shown in FIG. 1, the hinge is assembled and the door D of the game machine is attached to the casing C. At this time, the door D is held so that the bearing member 3 is first aligned with the shaft holding portion 13 on the fixing member 11 side and the inner wall of the concave portion of the bearing member 3 is brought into contact with the side surface of the shaft holding portion 13 of the fixing member 11. To adjust the axial center position of the hinge pin 15 to the axial center position of the bearing hole 3a, and if the position of the door D is slightly lowered in this state, the hinge pin 15 automatically enters and fits into the bearing hole 3a. .

  At this time, the pin locking member 6 in the bearing member 3 slides forward by the spring force of the urging spring 7 after the locking portion 6a is pushed back by the hinge pin 15 and is slightly returned. As shown in FIGS. 13 to 15, the hinge pin 15 and the bearing member 3 are locked by entering the locking groove 15 a. As a result, the hinge movable member 1 and the fixed member 11 are assembled, and the door D of the movable member 1 is assembled to the fixed member 11 of the housing C through the hinge so as to be opened and closed. Due to the locking of the portion 6a, the door D is prevented from coming off.

  On the other hand, when performing operations such as adjustment and part replacement at the game machine maintenance inspection, when the hinge movable member 1 is removed from the fixed member 11 and the door D is removed from the housing C, as shown in FIG. In the state where the door D is opened to the intermediate position, the pressing tip 8d of the slide member 8 protruding from the upper surface of the bearing member 3 is pushed into the bearing member 3 as shown in FIG. As a result, as shown in FIG. 16B, the inclined engaging portion 8b of the slide member 8 slides downward, and as shown in FIG. 17, the spring holding portion 6b of the pin locking member 6 is inclined. The locking portion 6a is slid by being pushed rearward by 8b, and the locking portion 6a is disengaged from the locking groove 15a of the hinge pin 15. At this time, the slide member 8 is in a state of being pressed laterally (forward) by the biasing spring 7 via the spring holding portion 6b, and the state in which the pin locking member 6 is unlocked is held. . Therefore, by lifting the door D in this state, the bearing member 3 of the movable member 1 is detached from the hinge pin 15 of the fixed member 11 and the door D is detached from the housing C.

  Thus, with the door D opened, the movable member 1 of the hinge can be easily operated by simply pushing the pressing tip 8d projecting from the upper surface of the bearing member 3 of the movable member 1 into the bearing member 3 from above. Can be removed.

  When the slide member 8 is pushed into the bearing member 3, the slide member 8 is pressed in the lateral direction by the biasing spring 7 via the spring holding portion 6b. Held in position. For this reason, if the slide member 8 is pushed in, the operator can easily remove the movable member 1 of the door D from the fixed member 11 of the casing C using both hands. Thus, when the door D (movable member 1) is opened, the upper surface of the bearing member 3 is opened, and in this state, the slide member 8 is pushed in and the locking portion 6a of the pin locking member 6 is slid rearward. The movable member 1 can be removed by moving.

  Thus, when performing operations such as adjustments and parts replacement at the time of maintenance and inspection of the game machine, the movable member 1 of the hinge is removed from the fixed member 11 and the door D is removed from the housing C, so that the operation can be performed quickly. it can. Of course, when the door D is closed, as shown in FIG. 1, the base frame body 2 of the movable member 1 and the mounting plate portion 12 of the fixing member 11 cover the bearing member 3, and the stopper portion 3 c of the fixing member 11. Since it is in contact with the lower surface of the shaft holding part 13, it is impossible to remove the movable member 1, and the security of the game machine is ensured.

  On the other hand, when the movable member 1 separated from the fixed member 11 is assembled to the fixed member 11, the bearings of the upper, middle and lower bearing members 3 of the hinge movable member 1 with the door D opened, contrary to the above. The holes 3 a are fitted into the upper, middle, and lower hinge pins 15 of the fixing member 11 of the housing C.

  At this time, the door D is held so that the bearing member 3 is first aligned with the shaft holding portion 13 on the fixing member 11 side and the inner wall of the concave portion of the bearing member 3 is brought into contact with the side surface of the shaft holding portion 13 of the fixing member 11. To adjust the axial center position of the hinge pin 15 to the axial center position of the bearing hole 3a, and in this state, if the position of the door D is slightly lowered, the hinge pin 15 automatically enters the bearing hole 3a, The bearing member 3 can be easily fitted into the hinge pin 15.

  Thereafter, if the movable member 1 of the door D is rotated so as to be closed with respect to the fixed member 11, the shaft holding portion 13 of the hinge pin 15 is rotated as shown in FIG. The inclined surface 8c is pressed, whereby the slide member 8 is pushed upward.
