A pair of cutout surfaces running in the front-rear direction of the operation groove 111 are operation surfaces 112 and 112 for rotating the engagement piece 106. As described above, in the present embodiment, the operation wall 111 is formed by cutting the cylindrical wall of the interlocking cylinder 92 into a quadrant, and the operation groove 111 is changed from the locking operation force of the cylinder lock 91 to the unlocking operation posture. It is a relief notch to absorb the posture displacement. In other words, even when the key 101 inserted into the key hole 100 of the cylinder lock 91 is set in the lying position and then returned to the vertical position, the operation surface 112 does not contact the engagement piece 106, and thus the return is performed. Depending on the operation, the operation arm 94 is not rotated, and the posture state of the stopper 95 is maintained.

  As shown in FIG. 9, both engaging pieces 106 and 106 are formed so as to protrude from the outer peripheral surface of the operation shaft 105 in different directions. In the present embodiment, one engagement piece 106 is formed in a state of being directed in a direction 90 degrees different from the other engagement piece 106. In response to the rotation of the operation shaft 105, the cam 93 is displaced between the recumbent posture shown in FIG. 10 and the vertical posture shown in FIG.

  The stopper 95 is a resin molded product. The stopper main body 114 extends in the vertical direction, the passive piece 115 is formed at the lower end of the stopper main body 114 and contacts the cam 93 of the operation arm 94, and the left side of the stopper main body 114. It has a spring support 116 that protrudes. As the cam 93 is displaced from the recumbent posture to the vertical posture, the stopper 95 is retracted from the rotation locus of the hook 48 (FIG. 10), and the upper end of the stopper body 114 is supported by the lock mechanism 11. It can be displaced in the vertical direction between the locking position (FIG. 11) that enters the doorway 55 provided in the plate 46, reaches the rotation locus of the hook 48, and prevents its swinging rotation. A thin guide piece 117 is provided at the upper end of the stopper main body 114, and the guide piece 117 is always located in the exit / retreat port 55, thereby preventing the stopper 95 from being inadvertently displaced in the front-rear direction. Thus, the upper end of the stopper main body 114 is prevented from coming into contact with the peripheral edge of the exit / exit 55.

  A torsion coil-shaped spring 96 is interposed between a boss 118 projecting from the upper surface of the spring receiver 116 and a boss 119 projecting from the spring receiver on the housing 45 side. The entire stopper 95 is urged to move toward the downward unlocking posture.

  In FIG. 9, reference numeral 120 denotes a kick spring that urges the cam 93 to rotate, and the kick spring 120 is attached to each of the protruding ends of the spring arms extending from both ends of the coil portion 121. It is made of a torsion coil spring forming 122, and one latching portion 122 is latched and attached to a latching pin 123 formed on the side surface of the cam 93, and the other latching portion 122 is attached to the housing 45 so as to surround the cam 93. It latches on the latch pin 125 formed in the side surface of the engagement piece 124 to be mounted.

  As described above, when the kick spring 120 is applied to the cam 93 provided on the operation arm 94, the center of the latch pin 123 connects the center of the latch pin 125 and the center of the operation shaft 105 when the posture of the cam 93 is switched. 10 and FIG. 11, the posture of the kick spring 120 changes greatly. As a result, the rotational moment by the kick spring 120 acts in the opposite direction with respect to the cam 93, so that the operation arm 94 switched to the recumbent posture or the vertical posture can be held in each posture.

  This locking device can be assembled by simply mounting and fixing each of the lock mechanism 11 and the handle 12 to the movable column 7 independently. More specifically, the release mechanism 13, the slide block 35, the interlocking arm 37, and the like are assembled in advance in the housing 45 and the handle case 23 in which the lock mechanism 11 and the unlocking mechanism 90 are assembled in advance. Each of the handles 12 made into parts can be assembled by being separately mounted and fixed to the movable column 7. By attaching and fixing the handle 12, the distal end of the interlocking arm 37 engages with the engagement recess 74 of the hook 48 of the lock mechanism 11, thereby establishing a positive mechanism from the release trigger 13 to the lock mechanism 11.

  As described above, according to the locking device according to the present embodiment, troublesome alignment work between the interlocking arm 37 and the hook 48, which is unavoidable when the interlocking arm 37 and the hook 48 are coupled and fixed by screws or press-fitting.

As shown in FIG. 3, the stopper 95 of the locking mechanism is in the unlocked posture. The release trigger 13 is in a normal posture.

  If the handle 12 is grasped from this state and the movable column 7 is operated in the closing direction (left direction) approaching the support column 9, the inclined posture of the inclined beam 4 is changed and the entire door body 5 is extended in a pantograph manner. Can do. When the movable column 7 reaches the position opposed to the support column 9, the front and rear positions of the movable column 7 are generally positioned so that the projection 83 can enter the guide recess 84, and the movable column 7 abuts the support column 9. Thus, the gate 2 is operated in the closing direction. 7, the hook 48 is inserted and loaded into the opening 80 of the striker 10, and the hooking claws 73 of the hooking arms 70 are engaged with the peripheral edge of the opening of the striker 10. The engagement fixed state with respect to the two support pillars 9 can be established. When inserting and loading the hooking pawl 73 into the striker 10, as shown in FIG. 6, the hook 48 can be inserted into the striker 10 using the protruding end of the hooking pawl 73 as a guide. That is, since the protruding end of the latching claw 73 is formed in a tapered shape, the protruding end is pushed against the opening edge of the striker 10 as the gate 2 is closed, and the latching arm 70 is unlocked from the locked position. The posture can be easily displaced to the locked posture.

  From this engaged and fixed state, the locking mechanism 90 is operated to lock the hook 48 in the locked posture. Specifically, by inserting the key 101 into the key hole 100 of the cylinder lock 91 and rotating it by 90 degrees, the operation arm 94 is rotated through the interlocking cylinder 92 and the cam 93 is moved from the lying position to the vertical position. Displace. Accordingly, the hooks 48 can be fixed in the locked posture with the stopper 95 in the locking posture as shown in FIG. More specifically, when the key 101 inserted into the keyhole 100 is rotated 90 degrees so that the key 101 changes from the vertical posture to the recumbent posture, the engagement piece 106 is formed on one operation surface 112 of the operation groove 111 of the interlocking cylinder 92. When pushed, the operating arm 94 rotates, and the cam 93 can be displaced from the lying posture to the vertical posture. At this time, when the center of the latch pin 123 exceeds the dead point on the straight line connecting the centers of the latch pin 125 and the operation shaft 105, the cam 93 is rotationally displaced to the vertical posture side by the elastic force of the kick spring 120. .

  In order to remove the key 101, it is necessary to displace the key 101 from the recumbent posture to the vertical posture, and the interlocking cylinder 92 is also rotated with the displacement of the posture. However, as described above, since the operation groove 111 is a relief notch that can absorb the displacement of the cylinder lock 91 from the locking operation posture to the release operation posture, the operation surface 112 is not related to the rotation operation of the interlocking cylinder 92 at this time. The entire operating arm 94 including the cam 93 is not rotationally displaced without contacting the joint piece 106. Therefore, the stopper 95 is maintained in the locking posture.

  When the gate 2 is opened, the unlocking operation is performed in the reverse procedure. That is, the key 101 is inserted into the keyhole 100 and rotated from the vertical position to the horizontal position. Thereby, the cam 93 of the operation arm 94 is rotated and displaced from the vertical posture to the horizontal posture while receiving the elastic force of the kick spring 120 via the interlocking cylinder 92, and the stopper 95 is displaced from the locked posture to the unlocked posture. Incidentally, the rotational operation directions of the front and rear cylinder locks 91 in the locking operation and the unlocking operation are different. In the present embodiment, the front cylinder lock 91 can be locked by rotating the key 101 counterclockwise, and can be unlocked by rotating the key 101 clockwise. On the other hand, the rear cylinder lock 91 can be locked by rotating the key 101 clockwise and can be unlocked by rotating the key 101 counterclockwise.

After the unlocking operation, the gate 2 is opened. In the opening operation, the grip portion 22 of the handle 12 is grasped with fingers, and the release trigger 13 is pushed in at the same time to displace the release trigger 13 from the normal posture to the release posture. By the pushing operation of the release trigger 13, the slide block 35 is slid from the normal position to the operation position by the engaging claw 29, and the interlocking arm 37 is oscillated and displaced around the oscillating shaft 36. As a result, both hooks 48 are displaced from the locked posture to the unlocked posture, the engagement and fixing state of the gate 2 with respect to the support pillar 9 is released, and the subsequent opening operation of the gate 2 becomes possible. However, the pushing operation direction (D1) of the release trigger 13 matches the opening operation direction (D2) of the gate 2 (see FIG. 4). Therefore, for the purpose of performing the opening operation of the gate 2, when the grip portion 22 is grasped with a finger, the release mechanism 13 can be simultaneously pushed to release the lock mechanism 11. More say, along with the fingers to release the trigger 13, only operated to move the gates 2 in the opening direction, by the pressing operation of the release trigger 13 simultaneously, it is possible to release operation of the lock mechanism 11. Therefore, according to the gate locking device according to the present embodiment, the gate 2 can be opened easily and quickly without being aware of the pushing operation of the release trigger 13. The operability is greatly improved.

  As described above, according to the gate locking device according to this embodiment, the pushing operation direction (D1) of the release trigger 13 provided on the handle 12 from the normal posture to the release posture is changed to the opening operation direction of the gate 2 ( D2), the opening operation of the gate 2 and the unlocking operation of the lock mechanism 11 can be simultaneously performed with one touch, and the opening operation of the gate 2 from the engaged and fixed state can be performed quickly and with little effort. Can do. Further, since the operation direction of the release trigger 13 and the opening operation direction of the gate 2 coincide with each other, there is no possibility of erroneous operation of the release trigger 13 and the gate 2 can be reliably opened from the engaged and fixed state. .

  In the above embodiment, the lock units 91 are provided on the front and rear handles 12, but the present invention is not limited to this, and the lock unit 91 may be provided only on one handle 12. Furthermore, the locking mechanism 90 including the lock unit 91 may not be provided at all, and only the temporary lock may be performed on the striker 10 by the lock mechanism 11. The form of the gate 2 is not limited to the pantograph type. The release trigger 13 is not limited to a configuration that can swing on the horizontal shaft 26, and may be configured to be slidable with respect to the handle 12. In short, the push trigger operation direction (D1) from the normal posture to the release posture of the release trigger 13 ) And the opening operation direction (D2) of the gate 2 need only coincide.

  The locking device according to the present invention can be applied to the gate door 2 having a pair of left and right door bodies 5 and 5 as shown in FIG. In this case, the lock mechanism 11 may be provided on the movable column 7 of one door body 5 and the striker 10 may be provided on the movable column 7 of the other door body 5. The locking device according to the present invention can be applied to a sliding door or the like.
