  The present invention relates to a locking device in a sliding sash window or the like.

  According to the Tokyo Metropolitan Police Department's targeted crime prevention records, about 70% of glass-breaking techniques are used in the crime intrusion method, and 90% of those who fail to intrude within 10 minutes. Statistical surveys to give up the intrusion have been announced, and it has been desired to provide a double lock device and a crescent lock with a lock that are protected against crime.

  As means for solving such a problem, for example, a sash window locking device (Japanese Patent Laid-Open No. 20003-3716), which is embedded in the sash window to make it difficult to see from outside, has been proposed. By breaking the glass and using a reflection mirror and a special deformation tool, the crime is easily carried out within the time required for fraud removal based on the aforementioned investigation data.

  Further, a sliding door locking device (Japanese Patent Laid-Open No. 10-184132) using a combination of a crescent lock and an automatic locking device has been proposed. However, the position of the automatic locking device has been confirmed from the outside by an unauthorized intruder. Although it requires an action to break the glass, the automatic locking device itself is destroyed by a driver or the like through the sash window gap, and the crime is easily carried out.

Also, a crescent lock with a double lock mechanism (Japanese Patent Laid-Open No. 2003-176655), which is a combination of a crescent lock and a knob lock lock, has been proposed, but the glass of the sash window can be easily broken with a screwdriver, etc. It is a structure in which the lock lock is illegally released from between.

  In view of the above problems, the present invention is capable of breaking or illegally releasing one of the locks of the double lock lock by some method as long as the lock device itself is exposed and attached to the outside of the sash window. , A lot of time spent on fraud removal as a countermeasure to prevent the crime, embedded in a sash window, difficult to manipulate illegally from the outside, difficult to see from the outside, and the distinction between main lock lock and sublock It is intended to provide a locking device that prevents unauthorized entry by vacant nests by providing comprehensive security elements such as being difficult to judge from the outside and interlocking with a limited unlocking order. To do.

  In order to achieve the above-mentioned object, the present invention provides a main lock lock and a sub-lock that are arranged in a sumo-shoi summon bowl, a slide plate installed in the sumo-shoe summon bowl, A locking device such as a sliding sash window comprising a lock receiver provided on a mating bar, wherein the main lock lock is a rotating cylinder structure having an operation knob, and a locking hook is formed at the tip of the cylinder In addition, a notch cam is formed at a predetermined position near the tip, and the sublock is a rotating cylinder structure having an operation knob, and a locking hook is formed at the tip of the cylinder and close to the tip. A double lock with a structure in which a locking groove is provided at a predetermined position, and the slide plate is provided with a locking hole for loosely inserting a locking hook formed on the sub-lock. It has become a location.

  Moreover, this invention can be set as the structure which provided the dial unlocking mechanism in the knob for operation in the said main lock lock.

  Furthermore, this invention can be set as the structure which provided the dial unlocking mechanism in the operation knob in the said sublock.

  In addition, the present invention can have a structure in which a dummy dial unlocking mechanism is provided on the operation knob of the sublock.

  According to the double lock device according to the present invention, the main lock lock and the sublock lock are doubled on the summon of the inner sash window such as the sliding sash window as to the structure that requires a lot of time for the unauthorized release. By attaching the main lock lock and the sublock lock separately, the criminal must break the glass in two places near the lock lock. By aiming for the need to defeat, the goal is to spend more crime time.

  Further, according to the double lock device mechanism of the present invention, the structure is embedded in the sash window summoning tub and is difficult to be tampered with from the outside. By providing it in the summoning jar, it can be prevented from being illegally destroyed by a driver or the like from the gap of the sash window jar.

  Furthermore, if the sash window is exposed and attached to the side surface of the sash window like a crescent lock, there is a possibility that the glass window can be easily broken from the outside and an unauthorized release operation can be performed. If the unlocking direction is in the indoor direction as in the double lock device, it is possible to make it difficult for the criminal to perform the unauthorized release operation.

  In addition, since the conventional double lock device is exposed to the outside of the bag, a skilled fraudster can work from the lock device that can be easily fraudulently released from the outside.
