状に形成された点にある。Therefore, this idea was developed to create a convenient lock that can be used as either an upper lock or a lower lock on the inside of a door, by simply installing the lock upside down. Therefore, its features include a lock base plate having a front-rear through-through operating port on the front surface and a support protrusion projecting from the rear surface, and an operating handle that is loosely fitted into the operating port. and a slider having a long hole inserted through the support protrusion and mounted on the rear surface of the lock base plate so as to be movable up and down, and a locking member movably provided on the slider, and the support protrusion. The lock is equipped with a presser plate externally supported so as to be movable back and forth under the guidance of the protrusion, and a presser spring that constantly presses the presser plate against the rear surface of the side edge of the elongated hole. Protruding portions that are relatively slidable through the back and forth movement of the presser plate are provided on both sides of the rear surface of the side edge located in the vertically intermediate portion of
The upper end surfaces of both peak origins are upper step portions that taper downward toward each other in the long hole direction, and the lower end surfaces are lower step portions that taper upward toward each other in the long hole direction, and each upper step portion and The sliding surface of the presser plate, which slides relative to each lower step portion in a detachable manner, is formed into a curved shape.

ロック状態が得られる。In the above configuration, when the slider 6 is moved downward by hooking a finger on the operation handle part 18 in the operation port 8 from the unlocked state shown in FIGS. 1 to 3, each of the lower stages of each raised part 20 Due to the relative sliding between the number of copies and the sliding surface 23b of the presser plate 23, the raised portion 20 of the slider 6 becomes as shown in FIG.
As shown by the broken line A, the presser plate 23 is moved rearward under the guidance of the support protrusion 11, and the rear surface of the protrusion 20 slides on the surface 23a between the presser plates 23, and the upper end inside the elongated hole 14 is moved to the rear side of the presser plate 23. When the intermediate surface 23a reaches the position 23a, the elastic force of the presser spring 24 causes the intermediate surface 23a of the presser plate 23 to fall from the rear surface of the raised portion 20 to the rear surface of the side edge portion 19, as shown in FIG. The engaging/disengaging portion 3 of the locking member 7 is pulled downward together with the slider 6 when the lower sliding surface 23b on the periphery of the locking member 7 engages with the upper step portion 21 of the raised portion 20.
0 is engaged in the recess 29 of the tool 28, and a locked state of the door 1 is obtained.

ら抜出されてそれとの係合を解除する状態が得られる。When the slider 6 is moved upward from the operation port 8 from this locked state, the presser plate 23 is once again moved rearward by relative sliding between each upper step 21 of each raised portion 20 and the sliding surface 23b. While holding it, the rear surface of the raised portion 20 is pressed against the presser plate 2.
When the lower end of the holding plate 23 is moved to the position of the holding plate 23 holding face 23a by sliding the long hole 14 as shown in FIG. The upper sliding surface 23 falls on the rear surface of the edge 19 and is located around the presser plate 23.
b becomes engaged with the lower step part 22 of the raised part 20, and the engaging/disengaging part 30 of the locking member 7, which is pulled upward together with the slider 6, is pulled out from the recessed part 29 of the receiver 28. and disengage it.

この状態で扉１の開きを自由とする。In this state, door 1 is allowed to open freely.

するようにしたものである。FIG. 8 shows another usage example in which the above-mentioned drop lock 2 is attached to the upper part of the inner surface of the door 1. The above-mentioned drop lock 2 is installed upside down and attached to the upper part of the inner surface of the door 1, and the lock member 7 is attached to the upper part of the inner surface of the door 1. Engagement/disengagement part 3
0 embedded in the upper frame 31 is adapted to engage and disengage from the recess 33 of the tool 32.

Sliding surface 23 of presser plate 23 that slides relative to each other
Since b is formed in a curved shape, when the slider 6 is moved up and down, the relative sliding between each step 21, 22 and the sliding surface 23b is smooth, and therefore the presser plate 23 can be moved back and forth smoothly. Therefore, the slider 6 can be moved smoothly, and by simply moving the slider 6 up and down, each step 21, 22 and the sliding surface 2 can be moved smoothly.
3b is automatically engaged and disengaged, making it easy to operate.

利点がある。As described above, the present invention has a raised portion 2 on the rear surface of the slider 6.
0 protrudingly provided on the upper and lower end surfaces of the raised portion 20. Since the lower step part 22 is configured to detachably engage with the periphery of the presser plate 23 as the presser plate 230 moves back and forth, unexpected downward movement of the slider 6 is prevented. There is an advantage that one lock can be used upside down by simply providing the stepped portion 22.

湾曲状に形成されたことを特徴とする錠。A lock base plate 5 having a front-rear through-through operating port 8 and a supporting protrusion 11 protruding from the rear surface, an operating handle portion 18 loosely fitted into the operating port 8, and a long hole inserted through the supporting protrusion 11. 14 and is mounted on the rear surface of the lock base plate 5 so as to be vertically movable, and a locking member 7 that is movable integrally with the slider 6. A presser plate 23 is externally supported so as to be movable back and forth under the guidance of the protrusion 11, and the presser plate 23 is inserted into the elongated hole 14.
In this lock, a presser spring 24 is attached which is always pressed against the rear surface of the side edge 19, and the presser plate 23 is moved back and forth on both sides of the rear surface of the side edge 19, which is located at an intermediate portion in the vertical direction of the elongated hole 14. Protruding portions 20 that are relatively slidable are provided to protrude from each other, respectively, and the upper end surfaces of the two peaks 20 form upper step portions 21 that taper downward in the direction of the elongated hole 14. are lower step portions 22 that rise in a tapered manner relative to each other in the direction of the elongated hole 14, and the sliding surface 23b of the holding plate 23, which slides relative to each upper step portion 21 and each lower step portion 22 in a detachable manner, is curved. A lock characterized by being formed into a shape.
