[0021]
First, as shown in FIG. 5, the multi-joint hinge 50 is formed in an L-shape for mounting on a mounting boss 68 (see FIG. 4) protruding from the multi-joint hinge mounting recess 28 of the front frame 12. The fastening bracket 51, a pair of upper and lower first arms 52 pivotally supported by a pivot 53 at the tip of the L-shaped short side of the fastening bracket 51, and slightly closer to the tip than the middle of the first arm 52 A pair of upper and lower second arms 54 that are pivotally supported by a pivot 55 and pivotally supported by a hanging bracket 56 having a locking piece 58 at a rear end thereof, and an L-shaped short side of the fastening bracket 51. One end of the second arm 54 is pivotally supported by the support shaft 60 and the other end of the second arm 54 is pivotally supported by the support shaft 61. A fourth shaft supported by a support shaft 64 at the tip of the first arm 52. And over arm 62, the latch member 56 is pivotally supported by the second arm 54 and the fourth arm 62, and a.
[0022]
In each of the above-described configurations, a locking piece 58 as an engaging portion protrudes from the front surface of the hanging metal piece 56. This locking piece 58 is formed on the front surface of the hanging metal piece 56 as shown in FIG. It has a structure in which a bowl-shaped flat plate protrudes upward. However, inclined notches 58a are formed on the left and right ends of the locking piece 58 to facilitate insertion into the mounting engagement recess 44. Further, the base portion of the first arm 52 and one end portion of the hanging metal fitting 56 are in contact with each other in a closed state, but a locking recess 65 is formed on the first arm 52 side of the contact portion. A locking projection 66 is formed on the hanging bracket 56 side. As shown in FIG. 4, the locking recess 65 and the locking projection 66 are fitted in a closed state, so that the backlash of the articulated hinge 50 in that state can be eliminated. As a result, this makes it difficult to form the gap (b) between the glass door frame 30 and the front frame 12, so that there is a merit that it is possible to prevent an illegal act by an unauthorized tool from the shaft support side. Furthermore, a mounting hole 67 is formed in the bottom surface portion of the L-shaped long side of the fastening bracket 51, and the mounting boss 68 projecting from the mounting hole 67 into the articulated hinge mounting recess 28 of the front frame 12. The articulated hinge 50 can be fixed to the front frame 12 by fixing with screws 69 corresponding to the above.
[0023]
In the multi-joint hinge 50 configured as described above, the quadrilateral connecting the support shafts 55, 57, 63, 64 is designed to be a parallelogram at all times, and the support shafts 55, 64 are connected in a closed state. The connecting straight line is designed to be parallel to the front frame 12. For this reason, the hook 56 connected to the support shafts 57 and 63 is also parallel to the front frame 12. The intersection of the straight line passing through the support shafts 55 and 57 and the horizontal line passing through the support shaft 60 is substantially the position of the support shaft 61. Thus, when moving from the closed state to the open state, the first arm 52 and the fourth arm 59 rotate clockwise, but as the first arm 52 rotates clockwise, the support shaft 61 rotates. Since it moves in the left direction of FIG. 4, in the initial stage, the support shaft 57 moves forward while moving in the right direction. The rightward movement of the support shaft 57 is until the support shaft 53 and the support shaft 64 are aligned on the horizontal line. When the support shaft 64 exceeds the horizontal line of the support shaft 53, the support shaft 57 starts to move in the left direction. Even if it begins to move to the left, the forward movement will not change. That is, the hanging piece 56 moves slightly in the right direction while moving forward in the initial stage, and then moves in the left direction while moving forward. Of course, at this time, the hanging bracket 56 is always parallel to the line segment connecting the support shafts 55 and 64, so that the inclination angle gradually increases in proportion to the rotation angle of the first arm 52. Since the first arm 52 is finally rotated until it is substantially perpendicular to the front frame 12 (in this embodiment, slightly larger than the right angle), the hanging bracket 56 is also substantially perpendicular.
[0024]
The articulated hinge 50 having the above-described configuration and operation is fixed to one side of the front frame 12 and the mounting plate 43 is fixed to the glass door frame 30, and the glass door frame 30 is attached to the front frame 12. As shown in FIG. 7, the glass door frame 30 is lifted and the mounting plate 43 is mounted in a state in which the hanging bracket 56 of the multi-joint hinge 50 is extended forward, that is, substantially perpendicular to the front frame 12. The engaging recess 44 can be inserted and attached to a locking piece 58 formed on the front surface of the hanging metal piece 56. Thereafter, when the open side of the glass door frame 30 is pushed and closed, as shown in FIG. 6, the upper end of the glass door frame 30 is prevented from moving upward by the removal preventing member 29, so the glass door frame 30 is closed. In the state, that is, the locked state, it is possible to reliably prevent an illegal act performed by removing the glass door frame 30 from the front frame 12.
[0025]
Further, in normal handling, as shown in FIGS. 8A to 8C, even if the ball lending outlet 7 of the interstitial ball lending machine 2 adjacent to the ball game machine 1 protrudes greatly, the glass door frame When the door 30 is opened, the glass door frame 30 is opened in a state of moving forward with respect to the front frame 12, so that the decorative members 32, 36 protruding from the front surface of the glass door frame 30 and the ball lending outlet 7 It can be opened largely avoiding contact, and does not interfere with simple repairs and inspections. Further, even when performing a complicated repair and inspection, the glass door frame 30 can be easily removed by lifting the glass door frame 30 with the glass door frame 30 open, so that a complicated repair and inspection can be easily performed. . In addition, when the glass door frame 30 and the front frame 12 are detachable at the time of manufacture, there is an advantage that the assembling work is simplified, and also when the glass door frame 30 needs to be replaced. Can be easily replaced.
[0026]
As described above, the detachable articulated hinge 50 may be used for the hinge structure of the outer frame 11 and the front frame 12 as shown in FIG. Further, the articulated hinge 50 may be fastened to the opening / closing frame, the mounting plate 43 may be provided to the support frame, the engaging portion is formed in a concave groove shape, and the engaged portion can be inserted. It may be formed as a simple insertion piece.
[0027]
【The invention's effect】
Thus, as is apparent from the description, in the present invention, the one side and below the support frame, while fastening the telescopic articulated hinges pantograph form, on one side and below the opening and closing frame, Since the mounting member with the engaged part that can be detachably engaged with the engaging part formed at the tip of the articulated hinge is fixed, the opening degree of the opening / closing frame with respect to the support frame is sufficiently secured. In addition, since the open / close frame can be freely attached to and detached from the support frame, repair and inspection can be performed very easily. In addition, by setting the open / close frame in a closed state with respect to the support frame, among the plurality of members constituting the multi-joint hinge, the engagement recess formed in one member and the engagement formed in the other member since the convex portion is on purpose fit engagement cormorants like, it can be eliminated rattling of the articulated hinge at that state, the consequently this is hardly possible the gap between the closing frame and the supporting frame There is a merit that fraudulent acts caused by fraudulent tools from the support side can be prevented.
