The lock 71 is an unlocking type lock referred to as a “double lock”, and the rotating shaft 73 is always biased and held at the neutral angle position when the unlocking operation is not performed, and fits the lock 71. By inserting and inserting the key into the keyhole portion 72, the rotation shaft 73 can be rotated clockwise or counterclockwise from the neutral angle position, thereby enabling the unlocking operation.

  A first cam plate 75 and a second cam plate 76 are fixed to a rotation shaft 73 that protrudes rearward from the lock 71 and is rotated by an unlocking operation. A partially enlarged view of the lock mechanism 70 in FIG. 6 is shown in FIG. 9 (A), and a front view of the first cam board 75 viewed in the direction of arrow B, which is appended to FIG. 9 (A), is shown in FIG. A front view of the second cam panel viewed in the direction of arrow C is shown in FIG.

  The first cam panel 75 has a wire locking portion 75Ra at two locations on the right and left of a predetermined dimension with respect to the axis O of the rotation shaft 73 (for example, a coordinate position with a radius R and an angle of ± 45 degrees from the axis O). , 75Rb are provided so that the terminal fittings fixed to the ends of the wires 43, 44 can be locked. On the other hand, the second cam panel 76 is wire-locked at two upper and lower positions on the left side of the same dimension with respect to the axis O of the rotation shaft 73 (for example, a coordinate position of an angle ± 135 degrees with a radius R from the axis O) The portions 76La and 76Lb are provided so that the end fittings fixed to the ends of the wires 43 and 44 can be locked in the same manner as the first cam board 75.

  The wires 43, 44 are not loosened between the wire locking portions 75Ra, 75Rb, 76La, 76Lb provided on the cam board and the wire locking pieces 54, 54, 64, 64 provided on each hook member. The locking device 4 is constructed by being stretched. Specifically, of the upper wire 43U and the lower wire 43L that connect between the upper and lower hook mechanisms 50U, 50L of the front frame locking device 41 and the lock mechanism 70, the upper wire 43U is the wire locking of the first cam panel 75. The lower wire 43L is connected to the wire locking portion 76Lb of the second cam panel 76. Of the upper wire 44U and the lower wire 44L connecting the upper and lower hook mechanisms 60U, 60L of the glass door locking device 42 and the lock mechanism 70, the upper wire 44U is connected to the wire locking portion 76La of the second cam panel 76. The lower wire 44L is connected to the wire locking portion 76Rb of the first cam board 76.

  That is, the upper wires connected to the upper and lower hook mechanisms 50U, 50L of the front frame locking device 41 when the first cam plate 75 and the second cam plate 76 are seen through from the front along the axial direction of the rotation shaft 73. 43U and the lower wire 43L are connected to the upper right (75Ra) and lower left (76Lb) target positions across the axis O of the rotation shaft 73, and are connected to the upper and lower hook mechanisms 60U and 60L of the glass door locking device 42. The upper wire 44U and the lower wire 44L are connected to the upper left (76La) and lower right (75Rb) target positions with the axis O interposed therebetween.

  Therefore, when a key suitable for the lock 71 is inserted into the key hole 72 and rotated clockwise or counterclockwise from the neutral angle position, the first cam panel 75 and the second cam panel 76 fixed to the rotation shaft 73 are used. Of the four wires connected to each cam board without loosening, tension is generated on the two wires on the pulling side. For example, when the key inserted into the key hole 72 is rotated clockwise from the neutral angle position as indicated by the solid line in the figure, the upper wire 43U connected to the wire locking portion 75Ra of the first cam panel, and the second wire The lower wire 43L connected to the wire locking portion 76Lb of the cam panel is pulled and a pulling force acts, and is transmitted to the hook member 51 of the upper and lower hook mechanism 50 connected to the other end side of these wires 43U and 43L. The

  In the hook member 51 of the upper hook mechanism 50U to which the upper wire 43U is connected, a downward force acts on the wire locking piece 54, and the rotating shaft 73 is moved against the spring force of the torsion spring 56 acting as a reaction force. When pivoting, the hook member 51 pivots clockwise around the pivot pin 55 in FIG. 6, and the hook portion 53 at the tip is slid upward to disengage from the receiving fitting 93. In the hook member 51 of the lower hook mechanism 50L to which the lower wire 43L is connected, when an upward force acts on the wire locking piece 54 and the rotating shaft 73 rotates against the spring force of the torsion spring 56, the hook The member 51 rotates about the pivot pin 55 in the clockwise direction in FIG. 6, and the hook portion 53 at the tip is swung upward to disengage from the metal fitting 93.

  At this time, since the lower wire 44L connected to the wire locking portion 75Rb of the first cam panel and the upper wire 44U connected to the wire locking portion 76La of the second cam panel are both on the loose side, the tension acts. Instead, the hook member 61 of the vertical hook mechanism 60 connected to the other end side of these wires is held in the locked position without swinging.

  On the other hand, when the key inserted into the key hole 72 is rotated counterclockwise from the neutral angle position as indicated by a two-dot chain line in the figure, the upper wire 44U connected to the wire locking portion 76La of the second cam panel, And the lower wire 44L connected to the wire locking portion 75Rb of the first cam panel is pulled and a tensile force acts, and is transmitted to the hook member 61 of the upper and lower hook mechanism 60 connected to the other end side of these wires. The

  In the hook member 61 of the upper hook mechanism 60U to which the upper wire 44U is connected, a downward force acts on the wire locking piece 64, and the rotating shaft 73 is moved against the spring force of the torsion spring 66 acting as a reaction force. When pivoting, the hook member 61 pivots counterclockwise in FIG. 6 with the pivot pin 65 as the center, and the hook 63 at the tip swings upward to engage with the receiving metal 94 (see FIG. 7). Is released. In the hook member 61 of the lower hook mechanism 60L to which the lower wire 44L is connected, when an upward force acts on the wire locking piece 64 and the rotating shaft 73 rotates against the spring force of the torsion spring 66, the hook The member 61 rotates about the pivot pin 65 counterclockwise in FIG. 6, and the hook portion 53 at the tip is swung upward to disengage from the receiving fitting 93.

  At this time, since the upper wire 43U connected to the wire locking portion 75Ra of the first cam panel and the lower wire 43L connected to the wire locking portion 76Lb of the second cam panel are both on the loose side, the tension acts. Instead, the hook member 51 of the vertical hook mechanism 50 connected to the other end side of these wires is held in the locked position without swinging.

  Thus, in the locking device 4, when the cam boards 75 and 76 are rotated in the unlocking direction based on the unlocking operation, the pulling force that acts on the wire from the cam board via the wires 43 and 44. It is transmitted to the hook member, and the hook member is configured to be displaced to the unlocked position. The wires 43 and 44 only need to be able to transmit tension. The upper frame 40U and the lower unit 40L are formed by separating the base frame up and down as in the present embodiment, and the substantially circular game area 11 is the rightmost. A locking device can be configured through a thin wire in a lateral region of the game board 10 that projects. For this reason, it is only necessary to secure a width through which the wire can pass to the side of the game board 10, and the other can be used as a game area. Therefore, it is possible to expand a game area that has conventionally been difficult to expand by providing a base frame having a certain width on the side of the game board 10.

  Furthermore, since the wires 43 and 44 are thin and flexible with a wire diameter of about φ0.5 to 1.2 mm, they can pass through a free path. Therefore, in the locking device 4 of the present embodiment, the wire guide structure 80 for guiding the wires 43 and 44 is provided, and the wires 43 and 44 are rotated by the first and second cam boards 75 and 76 at the side of the game area 11. The wire is guided so as to pass outside the shaft 73 (on the side opposite to the hinge mechanism).

  The wire guide structure 80 mainly includes an upper first roller 81 provided on the lower right side of the upper unit 40U and a lower first roller 83 provided on the upper right side of the lower unit 40L. In order to match the left and right positions of the wire locking portions in the first and second cam panels 75 and 76 with the left and right positions of the wire locking pieces in the upper and lower hook members 51 and 61, the upper unit 40U. 1 shows a configuration in which an upper second roller 82 and a lower second roller 84, a lower third roller 85, and a lower fourth roller 86 are provided in the lower unit 40L. The upper first roller 81 and the upper second roller 82 are rotatably attached to the upper base frame 45, and the lower first roller to the lower fourth roller are rotatably attached to the lower base frame 46. Instead of a cylindrical roller with a hook as shown in the figure, an individual pulley corresponding to each wire is provided (see FIG. 10), or a cylindrical pin is fixed and each wire is in sliding contact. Also good.

  And by this wire guide structure 80, the upper wires 43U and 44U connecting the lock mechanism 70 and the upper hook mechanisms 50U and 60U are moved back and forth on the right side of the rotation axis 73 of the lock 71 on the side of the game area. Guided to pass through. Specifically, the upper wire 43U locked to the upper right wire locking portion 75Ra of the first cam board 75 extends upward through the right side of the lower first roller 83, and the upper first roller 81 and It is guided to the left by the upper second roller 82, extends upward along the side surface of the upper base frame 45, and is connected to the wire locking piece 54 of the hook member 51. The upper wire 44U locked to the upper left wire locking portion 76La of the second cam board 76 is guided to the right by the lower second roller 84 and the lower first roller 83, and the rear of the upper wire 43U is moved upward. It extends to the left by the upper first roller 81 and the upper second roller 82, extends upward along the side surface of the upper base frame 45, and is connected to the wire locking piece 64 of the hook member 61.

  Regarding the lower wires 43L and 44L connecting the lock mechanism 70 and the lower hook mechanisms 50L and 60L, the lower wire 43L locked to the lower left wire locking portion 76Lb of the second cam panel 76 is a lower fourth wire. It extends downward along the side surface of the lower base frame 46 through the left side of the roller 86 and is connected to the wire locking piece 54 of the hook member 51. The lower wire 44L locked to the lower right wire locking portion 75Rb of the first cam board 75 is guided to the left by the lower third roller 85 and the lower fourth roller 86 and along the side surface of the lower base frame 46. And is connected to the wire locking piece 64 of the hook member 61.

  As described above, the wire guide structure 80 positively moves the upper wires 43U and 44U to the outside of the game area (the side opposite to the side where the hinge mechanisms 3a and 3b are provided). As indicated by the chain line, the game area 11 can be expanded to the right as compared to the game area 111 when the conventional locking device is provided, and the game area has been considered difficult to realize in the past. Can be further expanded.

  In the above, description of the detailed configuration is omitted for the sake of simplicity of explanation, but variations in the initial length of the wires 43 and 44 and length changes due to elongation are adjusted, and the wires 43 and 44 are always stretched without looseness. For this purpose, a length adjusting mechanism and a tensioner for preventing slack of the wire on the loose side according to the rotation direction of the lock 71 are provided. The wire guide structure 80 may be configured by providing an upper first roller 81 and a lower first roller 83 (an upper second roller 82 and a lower second roller 84 as necessary) on the front frame 2 side. is there. In addition, by enabling the wire guide structure roller to move left and right (or up and down), it is possible to provide a length adjustment function without providing a separate length adjustment mechanism. Thus, the wire guide structure can be configured more simply.

  In the embodiment described above, the configuration in which two front and rear cam panels are fixed to the rotating shaft 73 and the wire locking portions are formed at two locations in the upper and lower directions in the same direction of each cam panel is illustrated. Two wire locking portions may be formed on the diagonal line of the cam panel, or three or more wire locking portions may be formed on one cam disk.

  FIG. 10 shows a left side view similar to FIG. 6 as a locking device 4 ′ of such a modification, and FIG. 11 shows a front view of the cam panel 175 viewed in the direction of the arrow similar to FIG. 9 (B).

In this locking device 4 ′, the first cam plate 75 and the second cam plate 76 described above are formed as one cam plate 175, and wire locking is performed at four locations on the diagonal line passing through the axis O of the cam plate 175. Portions 175Ra, 175Rb, 175La, and 175Lb are provided. These four wire locking portions coincide with the formation positions 75Ra, 75Rb, 76La, and 76Lb of the wire locking portions when the first cam plate 75 and the second cam plate 76 are overlapped. In addition, as shown in FIG. 11, by connecting the upper and lower wires 43 </ b> U, 43 </ b> L, 44 </ b> U, 44 </ b> L, the same operations and effects as those of the locking device 4 described above can be obtained. In FIG. 11, the action when the key is rotated clockwise from the neutral angle position is indicated by a solid line, and the action when the key is rotated counterclockwise is indicated by a two-dot chain line. According to the locking device 4 ′ having such a configuration, the configuration can be simplified by reducing the number of cam boards to one.

  The position of the lock mechanism 70 can be set at an arbitrary position above or below the game area 11, for example, provided between the two hinge mechanisms 50L and 60L in the lower unit 40L, or the upper unit. It is also possible to arrange it at 40U. Moreover, although the rotation shaft 73 illustrated the structure using the one lock | rock 71, when it has two rotation shafts on the same axis | shaft and rotated the key clockwise from the neutral angle position, When the second rotation shaft remains in the neutral angle position, only the first rotation shaft rotates clockwise, and when the second rotation shaft rotates counterclockwise from the neutral angle position, the first rotation shaft remains in the neutral angle position. Locking the upper and lower hook mechanisms 50U and 50L on the diagonal line of the first cam panel fixed to the first rotating shaft using a lock that only the second rotating shaft rotates counterclockwise. In addition, the upper and lower wires of the upper and lower hook mechanisms 60U and 60L can be locked on the diagonal line of the second cam panel fixed to the second rotating shaft. According to such a configuration, it is possible to prevent sagging or deviation of the wire on the loose side without providing a tensioner (or with a simple configuration in which a tensioner having a small absorption stroke is provided).
