Since the blocking body was rotated around a shaft, it also had the disadvantage of being prone to failure.

[Means for Solving the Problems] The present invention, which solves the above conventional problems, provides an auxiliary lock for sliding sliding doors that is installed on the side stile of the outdoor sliding door to prevent the indoor sliding door from sliding. A single housing is attached to the indoor side of the horizontal stile of the outdoor sliding door, and within the housing, a blocking body and an operating body that appear on the running part of the indoor sliding door are arranged side by side in close proximity toward the indoor side. The blocking body and the operating body are each formed of separate members, the operating body is biased by a spring in a direction opposed to the direction of retraction, and the sliding member is linked within the housing. The blocking body is biased by a spring so as to be able to protrude and retract in the forward direction, and is locked and held by the sliding member in a retracted state, and has an inclined groove in one of the operating body and the sliding member, and a slanted groove in the other. is provided with a protrusion guided by the inclined groove,
By retracting the blocking body and retracting the slide member, the locking of the blocking body can be released.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a front view of a sliding sliding door equipped with an auxiliary lock according to an embodiment of the present invention, as seen from the indoor side, Fig. 2 is a partial perspective view of the area near the auxiliary lock of the sliding door, and Fig. 3 is a FIG. 2 is a sectional view of the auxiliary lock portion of FIG. 1;

The auxiliary lock 1 of this embodiment has a horizontal stile 21 at the bottom of the outdoor sliding door 21 of a double sliding door that has an outdoor sliding door 21 and an indoor sliding door 22 built into a frame 20 as shown in the figure.
It is attached to part a. Note that 25 is a crescent provided on the indoor sliding door 22.

The auxiliary lock 1 is attached to the side stile 2 of the outdoor sliding door 21.
1a, a first blocking body 5 and a second blocking body 6 provided in the housing 2, and a first blocking body 5 and a second blocking body 6 that operate the first blocking body 5 and the second blocking body 6 respectively. The operating body 7 includes an operating body 7, a second operating body 8, and slide members 9, 9.

As shown in FIG. 3, the casing 2 is fitted and fixed near the right end of the horizontal stile 21a in a state facing indoors. This housing 2 includes holding parts 3, 3 that hold the blocking bodies 5, 6 so as to be retractable, and an operating body 7,
Holding parts 4, 4 that hold the holding parts 8 in a retractable and retractable manner are provided alternately at regular intervals as shown in the figure. The holding parts 3 and 4 are each formed to have a rectangular cross section.

The blocking bodies 5 and 6 each have a hollow rectangular column shape that fits the holding parts 3 and 3, and are provided with a locking protrusion 10 projecting outward at the lower end. The blocking bodies 5, 6 are held in the holding parts 3, 3 so as to be retractable as shown in the figure, and are always urged in the projecting direction by springs 11, 11 provided in the holding parts 3, 3. . Due to the bias of the spring 11, the blocking bodies 5, 6
, the locking protrusion 10 is connected to the locking edge 3a of the holding part 3.
It protrudes toward the running portion of the indoor sliding door 22 to a position where it is locked. Then, the indoor sliding door 22 collides with either of the protruding blocking bodies 5, 6, and its sliding is blocked.

The blocking bodies 5, 6 can be completely immersed into the holding parts 3, 3 by pushing them back against the spring 11. Further, the blocking body 5 is positioned to lock the indoor sliding door 22 with the sliding door closed, and the blocking body 6 locks the indoor sliding door 22 with the indoor sliding door 22 open at a certain distance. It's located like that.

The operating bodies 7 and 8 are each formed into a hollow rectangular shape that fits the holding parts 4 and 4 of the housing 2.
It is held immersively within 4. Further, like the blocking bodies 5 and 6, they are always urged outward by springs 13 and 13 provided within the holding parts 4 and 4.
As shown in the figure, inclined grooves 14 and 14 are provided on both sides of the operating bodies 7 and 8, respectively.

The slide members 9, 9 are incorporated into the lower portions of the operating bodies 7, 8, are located within the holding parts 4, 4, and are slidable toward the holding part 4 through the opening 15 between the holding parts 3, 4. ing. Slanted grooves 14, 14 of the operating bodies 7, 8 are provided on both sides of the slide members 9, 9.
Protrusions 9a, 9a which are inserted and guided are provided. In addition, the holding parts 3, 3 of the slide members 9, 9
At the end of the side, there is a locking protrusion 1 of the blocking bodies 5 and 6.
Locking protrusions 9b, 9b that lock with 0 and 10 are formed.

Due to the above structure, when the operating bodies 7 and 8 are not pressed, the operating bodies 7 and 8 are biased by the spring 13 in a direction opposed to the retracting direction, so that the protrusions 9a and 9a are tilted. It is guided by the grooves 14, 14 and pushed toward the holding parts 3, 3 side. As a result,
The slide members 9, 9 slide toward the holding parts 3, 3, and the locking protrusions 9b, 9 project into the guide parts 3, 3 through the openings 15, 15. In this state,
When the blocking bodies 5, 6 are pushed and recessed into the holding parts 3, 3, the locking protrusions 10, 10 engage the slide members 9, 9.
It gets over the locking protrusions 9b, 9b and is locked to the locking protrusions 9b, 9b. Thereby, the state in which the blocking bodies 5 and 6 are retracted into the holding parts 3 and 3 is maintained. FIG. 3 shows a state in which the blocking body 6 is recessed.

In addition, when the operating bodies 7, 8 are pushed in the retracted state, the slide members 9, 9 retreat by the guide of the inclined grooves 14, 14, so that the locking protrusions 9b, 9b
comes off from the locking protrusions 10, 10 of the blocking bodies 5, 6,
The blocking bodies 5 and 6 protrude due to the bias of the spring 11. FIG. 3 shows a state in which the operating body 7 is pushed and the blocking body 5 protrudes. In this way, the blocking bodies 5 and 6 can be caused to protrude and retract with extremely simple operations.

When the blocking body 5 is protruded by the operating body 7 while the double sliding door is closed, the indoor sliding door 22 is locked to the blocking body 5, and its sliding is prevented. Therefore, in the closed state, the door can be double-locked by the crescent 25 and the blocking body 5 of the auxiliary lock 1, and the door locking of the sliding sliding door becomes stronger. When the blocking body 5 is retracted and the blocking body 6 is protruded, the indoor sliding door 22 is locked to the blocking body 6 at a position separated by a predetermined distance from the blocking body 5 to the blocking body 6. Therefore, the indoor sliding door 22 can be locked in an open state by the distance between the blocking bodies 5 and 6.

In the above embodiment, an auxiliary lock having two blocking bodies and two operating bodies has been described, but it is also possible to have one blocking body and one operating body. In addition, the housing 2,
Blocking bodies 5, 6, operating bodies 7, 8, slide member 9
The shape and the like are not limited to those shown in the drawings and can be modified in various ways.

[Effects of the invention] As explained above, according to the invention, the blocking body urged in the projecting direction by the spring is held in the retracted state by the sliding member, and the sliding member is moved backward by the operating body. By configuring the blocking body to be released from the lock and placed in the protruding state, an effect can be obtained in which the blocking body can be moved in and out with a simple operation of pushing the blocking body or the operating body. In addition, since the main components are only the blocking body, the operating body, and the slide member, the structure is extremely simple, and there are also advantages in that there are few failures and reliable operation can be performed.

Moreover, since the blocking body and the operating body are provided facing the indoor side of the housing attached to the indoor side of the sliding door, they cannot be seen from the outdoor side, which is advantageous for crime prevention and improves appearance. Moreover, since the blocking body and the operating body are constructed as separate members and are arranged in close proximity, they can be housed compactly in the housing, and they can be housed in a single housing. This allows the horizontal stile to be easily installed, and the operating body has a spring-based retractable structure that allows it to be operated with a single touch.
