Description

DETAILED DESCRIPTION OF THE INVENTION (1) Purpose of the Invention (Field of Industrial Use) The present invention relates to a sickle metal device of a sliding door that can be temporarily locked.

(Problems to be solved with the prior art) The edge of the sliding door and the pillar, frame, etc. that face and abut against the edge when the door is closed are provided with rotatable sickle metal and a receiving member for engaging and disengaging the same. The sickle lock is widely used for doors of houses, shutters of garages, etc.

This type of lock is operated by a cylinder lock from the outside, by manually operating the operating knob from the inside, or by activating a solenoid to move the operating plate inside the lock, and interlock with this. It is usual that the sickle metal is rotated so that the receiving member is engaged with the receiving member to lock it.

In such a known sickle lock, the sickle metal is locked to the operating plate with a pin, or the rack and the pinion are provided on the operating plate and the sickle metal, respectively. It was impossible to lock the door unless it was completely closed.

Therefore, even if the sliding door is closed, there is a possibility that the sliding door may move slightly in the opening direction due to external vibration or shock when it is closed, creating a gap, and there may be drafts or it may be unlocked. There were drawbacks such as lack of crime prevention.

The present invention has been made to cope with such a situation, and when the sliding door is closed, the sickle metal engages with the receiving member and is temporarily locked, and the door does not reverse and open due to impact or the like. In addition to the above, an object of the present invention is to provide a sickle lock device that can also be locked by a remote switch operation.

(2) Configuration of the Invention (Technical Means for Solving the Problem and Its Action) In order to achieve the above-mentioned object, the invention is formed on a motor arranged in the case of a sickle lock device and a rotary shaft of the motor. A sliding member that is screwed into a screw and is movable in the direction of the rotation axis, is rotatably disposed on a sliding member that has a protrusion at its end, and a shaft arranged in the case, and is wound around the shaft. A sickle that is always biased in the protruding direction by the mounted coil spring and has a protruding portion at a position adjacent to the protruding portion of the sliding member when the sliding member stops descending due to the driving of the motor. A sickle lock for a sliding door, comprising: gold; and a receiving member having a sickle portion that is elastically biased in a direction that engages with the sickle metal and that faces the sickle metal. It is a device.

With this configuration, the sickle metal can be automatically placed in the temporary locking position by closing the sliding door, and the sickle metal can be used as it is for the main locking.

(Explanation of Embodiments) FIG. 1 is a side view showing the inside of a sickle lock showing an embodiment of the present invention with the outer casing removed, and FIG. 2 is an exploded perspective view of essential parts.

Inside the case 1 of the sickle lock device A, the motor 2 is
, The shaft 4 of the motor 2 extends as shown in FIG. 2, and a male screw 5 is formed in the middle thereof.

The shaft 4 is loosely fitted in a through hole 6a provided in the sliding member 6, and the male screw 5 is screwed into a screw 7 for forming in the through hole 6a. The sliding member 6 is adapted to be displaced in the vertical direction.

A protrusion 6c is formed below the sliding member 6, and the protrusion 6c is a protrusion formed integrally with a sickle metal 8 which will be described later when the sliding member 6 is stopped by driving the motor 2. It is located near the portion 8a and prevents its displacement.

The sickle metal 8 is pivotally attached to a pin 9 at a proper position on the case 1, and a coil spring 10 is arranged on the pin 9. One end of the spring 10 is at a proper place 1'on the wall surface of the case, and the other end. Is engaged with the sickle metal 8 at a proper position to give the sickle metal 8 a turning habit in a counterclockwise direction as seen in FIG.

As shown in FIG. 2, a sickle portion 11 is provided at a position facing the sickle metal 8 at the edge of the sliding door provided with the case 1, the pillar facing the sill, the edge of the sill, or the sliding door. The sickle portion 11 is pivotally mounted by a shaft 12 provided on a pillar or door edge, and is biased by a spring 13 in a clockwise direction when viewed from the left side of FIG. It is assumed that the receiving member is formed at the position.

Further, the rotation center of the sickle metal 8 (center of the shaft 9) and the sickle portion 11
The center of rotation (the center of the shaft 12) is, as shown in FIG.
The point where 1 is engaged is on the extension of the center of rotation of the sickle portion 11.

With such a configuration, when the door is closed, the sickle metal 8 in the case 1 arranged on the edge of the sliding door, the pillar, the frame, or the like comes into contact with the sickle portion 11 on the opposite receiving member side. When the door is moved in the closing direction, both the sickle metal 8 and the sickle portion 11 rotate counterclockwise as viewed from the left side of FIG. 2 against the action of the springs 10 and 13, and the door is completely closed. When it is closed, the sickle metal 8 and the sickle portion 11 are engaged as shown in the figure, so that the sliding door can be prevented from unintentionally moving in the releasing direction due to an impact as described above.

When opening the door, if you pull it in the releasing direction, no rotational force acts on the sickle portion 11, so the sickle metal 8 escapes against the spring 10 and the sickle metal 8 and sickle portion 11 are engaged. It shall be removed.

In the temporarily locked state as described above, the motor 2 is driven to lower the sliding member 6, and the projection 6c of the sliding member 6 reaches the lateral position of the projection 8a provided on the sickle metal 8. When it is tightened, this serves as a stopper, and the sickle metal 8 cannot be rotated, that is, this means that the main lock is completed.

In the case of the device shown in the figure, the sliding member 6 driven by a motor is used to immobilize the sickle metal 8. However, as in the above-described known sickle lock, the sliding member 6 is a cylinder lock. Of course, it is also possible to manually slide with a knob or the like.

(3) Effect of the Invention As described above, according to the present invention, the sickle metal of the sickle lock is independently arranged, and when the door is closed, this automatically engages with the receiving member facing the sickle. I decided to lock it temporarily,
One sickle metal can be used for both temporary tightening and final tightening, and even when the sliding door is closed, it is possible to prevent going backwards due to shock or vibration and creating a gap, which also contributes to improving crime prevention. is there.
