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, 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. Therefore, the movable member cannot be attached and detached with the front door closed, and the front door is not enclosed. In the case of adjusting or exchanging electrical parts or the like after removing from the body, there has been a demand for a hinge that can easily remove the movable member from the hinge fixing member with the front door open.

  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 pin locking member having a locking portion for locking the hinge pin in the vicinity of the bearing hole of the bearing member can enter the locking portion into the locking groove of the hinge pin inserted into the bearing hole. Provided in

The pin locking member is provided with a pressing engagement portion that can contact the tip pressing portion of the operating rod, and the tip pressing portion of the operating rod inserted from the outside is the pressing engagement portion of the pin locking member. When the is pressed, the pin locking member slides in a direction away from the locking groove of the hinge pin against the spring force of the biasing spring.

  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.

When the pressing engagement portion of the pin locking member is pushed by the pressing portion, 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, the bearing member of the movable member of the first member is formed with a guide hole that communicates with the pressing engagement portion of the pin locking member, and when the operation rod is inserted, the tip pressing portion of the operation rod is guided by It can comprise so that it may approach from a hole and may press the press engagement part of a pin latching member. This guide hole is preferably provided at a position where the operation rod can be inserted when the door of the game machine is opened from the housing. According to this, the operating rod is easily inserted into the inside of the bearing member, and the pin engaging member is slid by simply pressing the pressing engagement portion with the tip pressing portion, and the locking portion is locked to the hinge pin. The first member on the movable side can be removed from the second member on the fixed side by removing from the groove.

  In addition, here, the pin locking member is provided with a display piece that protrudes from the outer surface of the bearing member and can be pulled back. The display piece slides on the pin locking member to lock the locking portion. It can be configured to display the release.

  According to the hinge of the present invention, the movable member is prevented from coming off during normal use, and when necessary for parts replacement or adjustment, it is fixed by pressing the pressing engagement portion of the pin locking member with the operating rod in the open state. The movable member can be easily removed from the member.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, this hinge is, for example, a vertically long hinge in which a movable member 1 serving as the first member and a fixing member 11 serving as the second member are detachably provided. As shown, for example, the movable member 1 is fixed to a door D of a game machine such as a slot machine, and the fixing 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. And the bearing member 3 which has the bearing hole 3a is each fixed to the lower part with the fixing screw 4 or a rivet caulking process.

  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, 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. The hinge pin 15 of the fixing member 11 is fitted into the bearing hole 3a, and the fixing member 11 is inserted. When the movable member 1 is assembled to the movable member 1 and the movable member 1 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 so that the movable member 1 is not detached. 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 3 a of the bearing member 3, the locking groove 15 a enters a locking groove 15 a into a locking portion 6 a of a pin locking member 6 to be described later. The hinge pin 15 is locked and acts as a retaining member.

  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 provided with a pin locking member 6 for preventing the hinge pin 15 inserted into the bearing hole 3 a from being detached. The pin locking member 6 is configured to have a locking portion 6a that is locked to a locking groove 15a provided in the vicinity of the tip of the hinge pin 15, and is formed in a slit formed in the upper portion of the bearing member 3. 5 is slidably accommodated in the front-rear direction. An urging spring (coil spring) 7 is disposed at the back of the slit and urges the locking portion 6a of the pin locking member 6 so as to protrude forward.

  As a result, as shown in FIG. 8, when the hinge pin 15 is inserted into the bearing hole 3a, the pin locking member 6 is retracted by receiving a pushing back load from the locking portion 6a, and the spring force of the biasing spring 7 The locking portion 6a enters the locking groove 15a of the hinge pin 15, and the hinge pin 15 is locked in the bearing hole 3a.

  Further, the pin engaging member 6 is formed with a pressing engagement portion 6b having an inclined surface at an upper portion thereof, and a guide hole 3e is formed in the bearing member 3 above the pressing engagement portion 6b. It is. As shown in FIG. 5 and the like, the guide hole 3 e is formed so as to open at an oblique upper portion of the front surface of the bearing member 3 and reach the pressing engagement portion 6 b of the internal pin locking member 6.

  Thereby, when the operating rod R is inserted from the guide hole 3e provided on the upper surface of the bearing member 3, the tip pressing portion engages with the pressing engaging portion 6b, and the pin locking member 6 is moved into the slit. It is structured to slide so as to push it back. As shown in FIG. 16, the shape of the pressing engagement portion 6 b of the pin locking member 6 is an inclined shape so that the pin locking member 6 is pushed back backward when pressed by the tip of the operation rod R from obliquely above. It is.

  In the hinge used in the game machine, when the opening angle of the movable member 1 with respect to the fixed member 11, that is, the opening angle of the door D with respect to the housing C is as small as about 60 degrees, for example, as shown in FIG. Since the mounting plate 12 is positioned so as to cover the bearing member 3, it is difficult to remove the movable member 1 from the fixed member 11 by operating the display piece 6 c in this state.

  For this reason, a guide hole 3e for the operation rod R is provided, and the guide hole 3e is provided from the front surface to the pressing engagement portion 6b of the pin locking member 6 in order to facilitate the removal operation of the movable member 1. When the predetermined operating rod R is inserted into the guide hole 3e and pushed in, the locking portion 6a is pulled back, disengaged from the locking groove 15a of the hinge pin 15, and the bearing member 3 is detached from the hinge pin 15. It is possible.

  As shown in FIG. 5, a display piece 6 c is projected from the front portion of the pin locking member 6. The display piece 6c protrudes forward from a slit 3f opened on the front surface of the bearing member 3, the operation rod R is properly inserted, the pin locking member 6 is properly slid, and the locking portion 6a is locked. When it is released, the display piece 6c is pulled back into the slit 3f to display it.

  Accordingly, when the operating rod R is inserted into the guide hole 3e, the release of the locking can be easily visually recognized by looking at the display piece 6c even if the tip of the operating rod R is not visible. In addition, if the display piece 6c is pushed in from the front in a state where the door is largely opened and the front surface of the bearing member 3 is largely opened, the pin locking member 6 is slid to engage the locking portion 6a. It is also possible to remove the stop.

  As shown in FIGS. 4 and 15, the left side wall of the base frame 2 having a U-shaped cross section is formed wider than the right side wall, and the movable member 1 is attached to the door D of the game machine for use. In this case, 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 and the door D of the game machine, and the long base frame body The bending strength of 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.

  As shown in FIGS. 9 to 11, the fixing member 11 has a mounting plate portion 12 made of a vertically long strip-shaped steel plate and an L-shaped cross-sectional portion 12 a extending on the side of the mounting plate portion 12. The mounting piece 12b is bent inward at the upper, middle, and lower portions of the side portion of the L-shaped cross section 12a, and the shaft holding portion 13 that holds the hinge pin 15 is attached to the mounting piece 12b. Composed. 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. .

  Thus, when the bearing hole 3 a of the bearing member 3 of the movable member 1 is fitted over 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 synthetic resin so that the hinge pin 15 protrudes and holds upward, and the shaft holding portion 13 is provided with an attachment hole. As shown in FIG. Each shaft holding part 13 is attached using the fixing screw 12c. 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 moved back. As shown in FIGS. 13 and 14, the locking pin 15 enters the locking groove 15 a and the hinge pin 15 and the bearing member 3 are locked. Thereby, the movable member 1 of the hinge and the fixed member 11 are assembled, the door D of the movable member 1 is assembled so as to be openable and closable via the hinge, and the door D is locked by the locking of the locking portion 6a of the pin locking member 6. Disengagement is prevented.

  On the other hand, when performing operations such as adjustment and parts replacement during game machine maintenance and inspection, when the hinge movable member 1 is removed from the fixed member 11 and the door D is removed from the housing C, the door D is opened to an intermediate position. In this state, as shown in FIG. 17, the operating rod R is inserted into the guide hole 3e of the bearing member 3, and the pressing engagement portion 6b of the pin locking member 6 is pushed in by the tip pressing portion. Thereby, as shown in FIG. 16, the pin locking member 6 slides backward, and the locking portion 6 a is detached from the locking groove 15 a of the hinge pin 15. Since the display piece 6c is pulled back to the inside when the pin locking member 6 slides, it can be confirmed that the locking of the locking portion 6a is released. 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.

  As described above, the hinge movable member 1 can be removed by a simple operation of inserting the operating rod R into the guide hole 3e of the bearing member 3 from above with the door D opened to the intermediate position instead of being fully opened. it can.

  When the operating rod R is inserted into the guide hole 3e, the operator can remove the operating rod R from the operating rod R if the pin locking member 6 is held in the retracted position by its own weight or by frictional resistance. It is possible to release the movable member 1 of the door D from the fixed member 11 of the housing C using both hands. Further, when the door D (movable member 1) is fully opened to the full open, the front surface of the bearing member 3 is opened. In this state, the display piece 6c is pushed in and the pin locking member 6 is slid rearward. The movable member 1 can also 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.
