In this embodiment, since the door 1 is an outwardly opening type door, a push-operation type is used as the inner handle 38 and an outer handle is used.
Although a pull-operated type is used as each 39, a push-operated handle may be used on the outside of the door 1 and a pull-operated handle may be used on the inside of the door 1 that opens inward. In this case, it is necessary to further reverse the direction of the latch 27 from the state shown in FIG. 3, attach the thumb turn knob 71 to the handle attachment seat on the indoor side, and attach the key plug 89 to the handle attachment seat on the outdoor side.

Further, in the illustrated embodiment, the suspension element is applied to the door 1 on the right side, but for the door 1 on the left side of the suspension element, the lock body 6 is reversed from the state shown in FIG. The inner handle 38 and the outer handle 39 may be attached together with their assembly by reversing the vertical position.

(Operation) In the push-pull lock configured in this way, most of the components on the inner handle 38 side and the outer handle 39 side are common, so their production and management are rationalized, improving productivity and reducing costs. In addition to being able to reduce the number of them, most of them have the same assembling method, so that they can be reasonably assembled using the same equipment and tools.

In this way, the inner handle 38 side and the outer handle 39 side
After assembling each side assembly, when attaching them to the door 1, check the opening and closing type of the door 1 and the hanging source, that is, check whether the door 1 is open inside or outside, and hang it right or left. Check whether or not to use it and determine the handle and mounting position accordingly.

In the case of the embodiment, since the door 1 is open outward and is hung on the right,
A push-type handle is used for the inner handle 38 on the indoor side, a pull-type handle is used for the outer handle 39 on the outdoor side, and a handle mounting seat on the push-side is used.
42 is equipped with a thumb turn knob 71, and a handle mounting seat 42 on the pulling side is equipped with a key plug 89.
In this case, the thumb turn knob 71 and the key plug 89 can be assembled in a timely manner according to the usage state of the door 1.

When various attachment parts are prepared in this way, the door 1

On the other hand, a troyooke accommodation hole (not shown) is formed at a corresponding position of the vertical frame 2, a troyooke 32 is accommodated in the hole, and a seat 30 is superposed on the outside of the troyoque 32 to form these. Screw 34
Fixed together through. In this case, since the lock attachment hole 4 accommodates the tubular type lock body 6, the lock attachment hole 4 is small in size and can be easily pierced as compared with the conventional one for accommodating a box lock.
This kind of installation is easy.

Then, the lock body 6 is housed in the lock mounting hole 4 and is fixed by a screw 8, and the pipe screw of the inner door assembly is inserted from the inside of the door 1 through the handle mounting hole 5.
The 84 and the connecting piece 40 are inserted into the through hole 35 and the empty space 37 of the lock body 6 after the attachment.

Also, the pipe screw 84 and the connecting piece 41 of the outer door assembly are inserted into the recessed hole 86 and the empty space 37 of the lock body 6 from the outside of the door 1 through the handle mounting hole 5, and the key plug 89 is inserted. When inserted in the holes 72, screws 85 are screwed into the pipe screws 84, 84 from the outside of each handle mounting seat 42, and these screws are tightened to fix both assemblies.

The handles 38, 39 mounted on the inner and outer surfaces of the door 1 in this way
1 is mounted vertically upward as shown in FIGS. 1 and 2, so that the external appearance of the mounting is improved without a complicated impression, as compared with the conventional one in which these are mounted sideways.

In such a push-pull lock, when the door 1 is closed, the latch 27 protrudes from the engaging hole 31 of the seat 30 into the troyooke 32,
Further, as shown in FIG. 6, the guide pin 28 is located at the bent end of the locking groove 26b, and restrains the protruding posture of the latch 27.

Then, in such a case, in the lock on the indoor side, the cam 74 attached to the thumb turn shaft 73 has fallen over as shown in FIG. 11, and the stopper plate 76 is placed at the normal lowermost position, so that the plate 76 The pin engaged in the fitting hole 78 has its head 60a.
It is held at the lowermost position via and the upper end thereof is located below the rotation range of the locking piece 69 as shown in FIG.

Therefore, the engagement piece 66 is rotatably placed in the direction of the door 1 about the pin 65, and the piece 66 receives the restoring force of the torsion springs 70, 70 and moves in the direction opposite to the door 1 about the pin 65. The inner handle 38 is urged toward the base end of the inner handle 38 to urge the handle 38 in the direction opposite to the door 1 about the pin 45.

Further, the base end portion of the connecting piece 40 is rotatably pivotally attached to the pin 60 on the overhanging piece 54, and its axis is normally directed obliquely forward in the direction of the empty space 37 to project to the base end portion. One of the provided engagement projections 57 is in slow contact with the inner surface of the engagement piece 66 as shown in FIG.

On the other hand, when using the lock on the outdoor side, the cam attached to the key plug 89
74 is falling as shown in Fig. 16 and stopper plate 76
Is placed in a normal lowermost position, its engaging projection 79 is similarly placed in the lowermost position, and the upper end portion thereof, as shown in FIG. 14 and FIG. It is located below.

Therefore, the engagement piece 66 is rotatably placed in the direction of the door 1 about the pin 65, and the piece 66 receives the restoring force of the torsion springs 70, 70 to rotate upward about the pin 65. Energized,
The urging force is applied to the base end portion of the outer handle 39 to urge the handle 38 to rotate upward.

Further, the base end of the connecting piece 41 is rotatably attached to the pin 88 on the overhanging piece 55, and its axis is normally directed obliquely forward in the direction of the empty space 37 to project to the base end. One of the provided engagement projections 58 is in slow contact with the inner surface of the engagement piece 66 as shown in FIG.

Under such a condition, for example, when the door 1 is opened from the inside of the room, a hand is put on the upper portion of the inner handle 38, or an arm is placed on the inner handle 38 to prevent the restoring force of the torsion spring 70. When pushed to the door 1 side, the base end upper portion of the handle 38 enters the inside of the handle mounting hole 43 and engages with the upper portion of the engaging piece 66 as shown in FIG. Press to.

In this case, in the above-mentioned handle operation, the contact with the handle 38 and the arm-resting posture are natural, and since it matches the operation direction,
Force is applied naturally and rationally, and operability is improved compared to the conventional one in which the handle is arranged sideways.

Thus, when the engaging piece 66 is pressed as described above, the engaging piece 66 is pressed.
The pin 66 rotates clockwise around the pin 65 in FIG. 9, and the inner surface of the pin 66 is displaced toward the connecting piece 40 to strengthen the engaging force with respect to the engaging projection 57 that is engaged slowly. As a result, the connecting piece 40 is pushed around the pin 60 in the clockwise direction in FIG. 10, and when the other engaging projection 58 engages with the inner surface of the engaging piece 66, its rotation is stopped. FIG. 18 shows the stop situation in this case.

Then, by displacing one end of the connecting piece 40 as described above, that is, by moving one end of the connecting piece 40 away from the latch 27 and moving backward, one end of the connecting piece 40 is slid in the lock body 9. The frame 21 is engaged with the locking portion 23 of the frame 21
Against the restoring force of the latch spring 25 and move it backward.

Thus, when the slide frame 21 begins to retreat and moves by the length of the locking groove 26b, the guide pin 28 relatively separates from the locking groove 26b, moves to the rear end of the inclined groove 26a, and latches 27. Release the restraint of.

Therefore, after this, the door 1 is gradually pushed open and the latch
When the tip portion of 27 starts to engage with the rim portion of the engaging hole 31 of the seat 30, the latch 27 is pushed around the guide pin 28 in the direction opposite to the rotation direction of the door 1, and at that time. The guide pin 28 moves forward along the inclined groove 26a, and the rotation of the latch 27 is promoted.

After that, the latch 27 is rotated while further retracting to engage the engaging hole 31.
When the locking portion 23 of the slide frame 21 comes into contact with the stopper 22 as shown in FIG. 19 and FIG. 20, the operation is stopped and the door 1 is opened. .

On the other hand, when opening the door 1 from the outdoor side, hold the upper part of the outer handle 39, or hook the arm inside the handle 39 and pull it toward the front against the restoring force of the torsion spring 70. As shown in FIG. 21, the lower part of the base end of the handle 39 enters the inside of the handle mounting hole 43, engages with the lower part of the engaging piece 66, and presses it toward the door 1.

In this case, since the handle 39 is naturally held or hung on the arm and is aligned with the operation direction thereof, a force is naturally and rationally applied as compared with the conventional one in which the handle is arranged sideways, Operability is improved.

Thus, when the engaging piece 66 is pressed as described above, the engaging piece 66 is pressed.
The pin 66 rotates counterclockwise in FIG. 14 around the pin 65, and the inner surface of the lower half of the pin 65 is displaced toward the connecting piece 41, so that the engaging force with respect to the engaging protrusion 58 that is engaged slowly is exerted. ramp up. As a result, the connecting piece 41 is pushed around the pin 88 in the counterclockwise direction in FIG. 15, and when the other engaging projection 57 engages with the inner surface of the engaging piece 66, its rotation is stopped. . FIG. 2 shows the stop situation in this case.

Then, by displacing one end of the connecting piece 41 as described above, that is, by moving one end of the connecting piece 41 away from the latch 27 and moving backward, one end of the connecting piece 41 is slid in the lock body 9. The frame 21 is engaged with the locking portion 23 of the frame 21
Against the restoring force of the latch spring 25 and move it backward.

After that, the latch 27 is released from the restraint in the same manner as described above, further pivots while retracting and is retracted into the lock case 9, and when the locking portion 23 of the slide frame 21 abuts on the stopper 22, those latches are released. The operation is stopped and the door 1 is opened.

As described above, according to the present invention, the displacement of the handles 38, 39 is changed to the engaging piece 6
6 and the connecting pieces 40, 41 convert the displacement in the same direction as the moving direction of the latch 27, and the connecting pieces 40, 41 move on the same level surface as the moving area of the empty space 37. Compared to the one in which the link for transmitting the displacement of the handle moves up and down or rotates, the displacement transmission mechanism is simpler, the number of parts required for this can be reduced, and the space can be saved.
Can be made smaller and lighter.

Next, when locking the push-pull lock after closing the door 1,
Thumb turn knob 71 provided on the handle mounting seat 42 on the indoor side
Is rotated 90 ° counterclockwise from the unlocked state shown in FIG.

By doing so, the cam 74 mounted on the thumb turn shaft 73 stands up as shown in FIG. 11, pushes up the stopper plate 76 engaged with the cam 74, and the pin engaged with the fitting hole 78 is engaged therewith.
60 moves together, and its upper end is positioned within the rotation range of the locking piece 69. Therefore, the pin 60 engages with the locking piece 69, and the inner handle 38 cannot rotate together with the engaging piece 66, and a locked state is formed.

On the other hand, when the thumb turn shaft 73 rotates as described above, the key plug 89 fitted in the plug insertion hole 72 moves together with the shaft 73, and the cam 74 rotates upright as shown in FIG. Similarly, the stopper plate 76 that engages with the cam 74 is pushed up, and the engaging projection 79 is positioned within the rotation area of the locking piece 69.

Therefore, the engaging piece 79 is engaged with the locking piece 69, and the engaging piece 66
At the same time, the outer handle 39 cannot be rotated, and a locked state is formed both inside and outside. (Effect of the invention) As described above, the push-pull lock of the present invention rotates the base end portions of the pair of handles in the vertical direction.
