Then, the hooking member 4 is pulled forward by the sickle piece K. At this time, by the action of sliding the sliding protrusion 40 of the engagement member 4 along the protrusion 53 of the fixed frame 5, the entire engagement member 4 moves horizontally and moves forward. In addition, the above-mentioned hooking member 4
Due to the horizontal movement of the hook 4, the spring 6 engaged with the hook 41 of the hook 4 is pulled forward and elastically deformed, and the hook 43 of the hook 4 is moved to the hook K.
The hooking portion 43 is tightly pressed against the sickle piece K, and the hooking portion 43 is tightly engaged with the sickle piece K.

In addition, when unlocking, if the sickle piece K is turned back to the sliding door D' side, the engaging member 4 is horizontally moved by the restoring force of the spring 6 and returns to the back side of the strike A.

Of the structure of the strike A explained above, the hooking part 43 formed on the hooking member 4 can be formed in an appropriate shape that can be easily engaged, corresponding to the shape of the sickle piece K to be the other party, In addition to the plate-shaped hook portion 43, a pin-shaped hook portion 43 may be formed.

As a structure for attaching the entire hooking member 4 so as to be horizontally movable, in addition to the sliding structure using the sliding ridge 40 of the hooking member 4 and the ridge 53 of the fixed frame 5 shown in the figure,
As long as the engaging member 4 can be moved horizontally within the fixed frame 5, it is possible to change the sliding mechanism to a fitting-based sliding mechanism having an appropriately uneven shape, with one side convex and the other concave.

In addition to the U-shaped linear spring shown in the drawing, the spring 6 may be a coil spring or a plate spring if it is installed between the engaging member 4 and the fixed frame 5 to urge the engaging member 4 toward the inner part. It is also possible to implement it with various spring mechanisms such as.

In the illustrated embodiment, a pull-lock mechanism 22 is provided on the back plate 2 so that it can be locked from the sliding door D on the strike A side, but the pull-lock mechanism 22 can be omitted if unnecessary. . In this case, the rear panel 2 may not be provided, and the engaging member 4 and the fixing frame 5 may be embedded in the sliding door D from the front panel 1 side.

Next, FIGS. 7 to 9 show modifications of the above-mentioned embodiment and the structure for attaching and moving the engaging member 4.

The overall shape of the hooking member 4 and the shape of the hooking portion 43 are the same as those in the above embodiment, but in this modified example, a pivot pin 44 is inserted through a part of the hooking member 4, and the pivot pin 44 is pivotably supported on a fixed frame 5, and the entire engaging member 4 is attached so as to be pivotable back and forth. By pivoting the hooking member 4 back and forth, the hooking portion 43 of the hooking member 4 can move in and out of the window portion 10.

Further, the spring 6 is configured such that one end of the hooking member 4 and the back surface of the fixed frame 5 are connected by a coil spring 6, and the hooking portion 43 of the hooking member 4 is pulled in the direction of pivoting toward the inner side. , is elastically biased.

In the above modification example, the pivot pin 44 of the hooking member 4 is provided below the hook portion 43, and the coil spring 6 is provided above the hook portion 43.
is provided above the latching part 43 and the coil spring 6 is provided below, or the end of the latching member 4 opposite to the latching part 43 is pressed forward with respect to the pivot pin 44. A spring 6 may be provided as shown in FIG.

In addition, Strike A of this invention is not only a sickle lock that is attached to the mating part of the sliding door as shown in the figure, but also a sickle lock main body is attached to the end face of the sliding door, and Strike A is attached to the doorstop part of the pillar or the end face of the other sliding door. It can also be applied to sickle locks for door openings.

<Effects> According to the strike of the sickle lock of this invention configured as described above, the engaging member forming the hooking portion for engaging the sickle piece can move the hooking portion into and out of the window portion. In addition to being attached, there is also a spring that elastically urges the hooking portion toward the back of the window, so that when the sickle piece is hooked to the hooking portion of the hooking member,
The hook can be pulled against the biasing force of the spring using the sickle piece to tightly engage the hook.

Therefore, even if there is a production error or play during installation between the sickle piece and the hanging part, the above mentioned play or error can be absorbed by the hanging part elastically moving in and out. Engagement with the stop part can be performed reliably.

And, as for the engagement state of the sickle piece and the hook part,
Since the springs make them contact each other elastically, the engagement is tight and strong, and it also pulls the sliding doors toward each other to eliminate gaps and looseness. It also has the effect of preventing it from sticking or moving.

Furthermore, when the lock is unlocked, the latch is housed inside the window, and only when it is locked, it is pulled by the sickle piece and advances to the front side of the window. The sliding door is flat, and there is no need to worry about the latch getting in the way of the sliding door moving or getting caught on people, and it is also excellent in terms of safety.

Therefore, it is possible to achieve a reliable and strong engagement between the sickle piece and the strike, which is difficult to achieve with conventional strikes in which the position of the hooking part is fixed, making it extremely practical as a strike for sickle locks. .
