[Action]
  The operation of the push-pull lock of the present invention will be described below based on this embodiment. In the present invention, the lock body and the handle itself, which are composed of the lock case and the lock mechanism parts, are replaced only by attaching the handle 2 vertically or horizontally without changing the position of the operation plate 9 connected to the handles 2 and 2. It can be selectively used as a vertical pull push-pull lock as shown in FIGS. 1 to 10 or as a horizontal pull push-pull lock as shown in FIGS.
[0044]
  That is, when it is desired to use a push / pull lock of a vertical handle, as shown in FIGS. 1 to 3, the handle is turned vertically and the free ends of the first operating plate 9a and the second operating plate 9b serving as the operating plates 9 are used. Is inserted vertically in the left and right sides of the through holes 1g and 1g formed in both side plates of the lock case 1A, and the handle 2 is preferably assembled to the door surface of the door a as described above.
[0045]
  When it is desired to use a push-pull lock of a horizontal handle, as shown in FIGS. 11 and 12, the handle is turned sideways, that is, the free ends of the first operating plate 9a and the second operating plate 9b, which are the operating plates 9, By rotating 90 ° counterclockwise from the vertical handle state, the through holes 1g and 1g are inserted horizontally into the upper and lower sides, and the handle 2 is assembled to the door surface of the door a as described above.
[0046]
  A case where the handle is a vertical type and a case where the handle is a horizontal type will be described below. In any case, for convenience of explanation, it is assumed that a dead bolt 91 for inserting and tightening a key (not shown) into the key hole of the cylinder 90 is retracted and unlocked.
(A) When the handle is a vertical type (FIGS. 1 to 10)
    When the door a is closed as shown in FIG. 1 from the opened state, the latch head 4 that normally protrudes from the entrance 1f of the lock case 1A by the restoring force of the latch spring 5 is inclined to the curved portion of the strike b1 on the door frame b side. 4a abuts, and the action of the inclined surface 4a causes the latch head 4 to retract once against the restoring force of the latch spring 5, and when it is inserted into the engagement hole b2 of the strike b1, it protrudes again and engages with the engagement hole b2. Enter.
[0047]
  At this time, the upper and lower engagement grooves 4d and 4d of the latch head 4 are engaged with the engagement pieces 12 and 12 of the locking pieces 10 and 10 at both upper and lower portions by the restoring force of the spring 13, and the latch head 4 is reversed. Therefore, even if the door a is pushed in the opening direction, the engagement state with the engagement hole b2 of the strike b1 is maintained, the latch is not reversed and the door is not opened. That is, the door is not locked due to wind pressure or the like.
[0048]
    In the above state, when the outdoor handle 2 is gripped or a finger is applied and pulled in the door opening direction, that is, toward the front, the handle 2 swings around the pin 71 of the pivot portion of the lower seat 3, and the handle 2 The first operation plate 9a which is the operation plate 9 pivotally supported by the connecting plate 8 provided on the upper part of the first rocker swings clockwise around the pin 70 and is inserted into the lock case 1A. The free end of the plate 9a engages with the horizontal plate portion 26 below the first mediation slider 21, and moves up the first mediation slider 21 (see FIG. 4). In conjunction with the upward movement of the first mediating slider 21, the first slider 22 also moves upward by a predetermined distance, and the horizontal plate portion 28 below the first slider 22 moves up the engaging portion 15 at the rear of the lower rocking piece 10. Therefore, the engagement piece 12 at the front of the lower locking piece 10 swings counterclockwise with the pivot 11 as a fulcrum, so that the lower engagement piece 12 is disengaged from the engagement groove 4d at the lower part of the latch head 4. The engagement is released after separation. At the same time, the upper locking piece 10 connected by the pin 14 swings clockwise against the restoring force of the spring 13, and the engagement piece 12 is separated from the engagement groove 4 d at the upper part of the latch head 4. Thus, the reversal prevention action of the latch head 4 is released (see FIG. 4). Therefore, the latch head 4 is reversed and retracted by the operation of pulling the handle 2 to be unlocked, and the door a can be opened.
[0049]
      When the dead bolt 91 is retracted and the latch head 4 moves forward and is locked and closed, when the handle 2 on the indoor side is pushed in the door opening direction, the handle 2 supports the pin 71 of the pivot portion of the lower seat 3. The second operating plate 9b, which is the operating plate 9 pivotally supported by the connecting plate 8 provided on the upper portion of the handle 2, swings clockwise with the pin 70 as a fulcrum, and enters the lock case 1A. The free end of the inserted second actuating plate 9b engages with the horizontal plate portion 26 on the upper part of the second mediating slider 23 to move the second mediating slider 23 downward. In conjunction with the downward movement of the second mediating slider 23, the second slider 24 is also moved downward by a predetermined distance via the horizontal plate portion 25 and the horizontal plate portion 27, and the horizontal plate portion 28 above the second slider 24 is locked upward. In order to move down the engaging portion 15 at the rear part of the piece 10, the engaging piece 12 at the front portion of the upper locking piece 10 swings clockwise with the pivot 11 as a fulcrum, so that the upper engaging piece 12 is The engagement is released away from the engagement groove 4d at the top of the latch head 4 (see FIG. 5). At the same time, the lower locking piece 10 connected by the pin 14 swings counterclockwise against the restoring force of the spring 13, and the engagement piece 12 is disengaged from the engagement groove 4 d below the latch head 4. The latch head 4 is released from the reverse blocking action (see FIG. 5). Therefore, when the handle 2 is pushed, the latch head 4 is reversed and retracted to be unlocked, and the door a can be opened.
[0050]
  (B) When the handle is a horizontal type (FIGS. 11 to 15)
      Also in the case of this horizontal handle, when the door a is closed as shown in FIG. 11 from the open state, the door is not locked due to wind pressure or the like for the reason described in (A) above.
[0051]
      When the dead bolt 91 is retracted and the latch head 4 is in the locked / closed state where the handle 2 on the outdoor side is pulled in the door opening direction, the handle 2 is attached to the pivot of the seat 3 on the door hinge part side. The first actuating plate 9a which is the actuating plate 9 pivoting on the connecting plate 8 provided on the free end side of the handle 2 is swung in the horizontal direction with the pin 71 as a fulcrum, and is swung in the clockwise direction with the pin 70 as a fulcrum. The free end of the first actuating plate 9a inserted into the lock case 1A pushes the contact piece 51b of the contact member 51 leftward (referred to as leftward movement), and the corresponding contact member 51 is shown in FIG. Swings clockwise. Since the upper locking piece 10 swings in the clockwise direction in conjunction with the swing of the abutting member 51, the front engaging piece 12 of the upper locking piece 10 swings in the clockwise direction with the pivot 11 as a fulcrum. As a result, the engagement piece 12 of the upper locking piece 10 is separated from the engagement groove 4d on the upper portion of the latch head 4 and is disengaged. At the same time, the lower locking piece 10 connected by the pin 14 swings counterclockwise against the restoring force of the spring 13, and the engagement piece 12 is disengaged from the engagement groove 4 d below the latch head 4. The latch head 4 is released from the reverse blocking action (see FIG. 13). Therefore, the latch head 4 is reversed and retracted by the operation of pulling the handle 2 to be unlocked, and the door a can be opened.
[0052]
      When the dead bolt 91 is retracted and the latch head 4 is in the locked / closed state, when the indoor handle 2 is pushed in the door opening direction, the handle 2 is attached to the pivot of the seat 3 on the door hinge part side. The second actuating plate 9b, which is the actuating plate 9 pivoting on the connecting plate 8 provided on the free end side of the handle 2 and swinging in the horizontal direction with the pin 71 as a fulcrum, is counterclockwise with the pin 70 as a fulcrum The free end of the second operating plate 9b inserted into the lock case 1A swings (to the right) the engaged portion 57 at the top of the swing member 52 in the right direction. In conjunction with the swing of the swing member 52, the lower locking piece 10 also swings counterclockwise with the pivot 11 as a fulcrum, so the engaging piece 12 at the front of the lower locking piece 10 has the pivot 11 as a fulcrum. As a result of swinging in the counterclockwise direction, the lower engaging piece 12 is separated from the lower engaging groove 4d of the latch head 4 to be disengaged. At the same time, the upper locking piece 10 connected by the pin 14 is swung clockwise against the restoring force of the spring 13, and the upper engagement piece 12 is engaged with the engagement groove 4 d at the upper part of the latch head 4. The inversion prevention action of the latch head 4 is released at a distance from (see FIG. 14). Therefore, when the handle 2 is pushed, the latch head 4 is reversed and retracted to be unlocked, and the door a can be opened.
[0053]
