[Prior Art]

 Conventionally, a door lock is generally known as a cylinder lock or the like which is attached to a door knob or a lower part of the knob, and a key or the like is inserted into a locking member having a keyhole to open and lock the lock. In addition, card locks, electronic dial locks, etc. are the latest door locks.

[0003]

[Problems to be solved by the device]

 Since the conventional door lock is generally an unlocking type with a key, it is troublesome to store, handle and carry the key after locking, and there is a concern that the key may be lost or forgotten. In addition, the lighting of electric lights when returning home at night is not sufficient because the door and the position of the lighting switch are separated, which makes it difficult to search for the switch in the dark.

[0004]

[Means for Solving the Problems]

 Therefore, the slide type character matching lock of the present invention uses a slide type character matching lock so that it can be used without a key, and it is a semi-circular rotatable lock body (A) and its lock body. It is composed of a vertically elongated guide track (B) and a moving body (C) that engages with the locking body and slides freely on the guide track, and a character matching lock is attached to the moving body. With a locking member that can be opened and locked by sliding it, attach an electric circuit changeover switch (a) at the position where the upper part of the storage cover and the upper part of the moving body come into contact with each other, and at the same time when locking and unlocking by sliding. By trying to turn on and off the interior lighting, the above problems will be solved.

[0005]

[Operation] The lock body (A) is a substantially semi-circular shape having a rotatable dead bolt, and the dead bolt projects downward by rotating downward with the support shaft of the lock body as a fulcrum and rotates upward. Due to the dead bolt retracting mechanism, the locking body has gear irregularities on the outer periphery and engages with the irregularities on the sides of the moving body.

The guide track body (B) is located along the lock body, has a convex vertically long track, and slides the moving body (C) in the track portion by meshing with the lock body (A). Thus, the convex portion (e) has a recessed groove (h) at the stop position of the moving body. The moving body (C) is equipped with a character matching lock, meshes with the lock body (A), is inserted into the proposed track body (B), and is manually slid from the door surface side.

When locking, when the raceway body is slid downward and the rotary disc (key) of the character alignment lock is turned and locked in the recessed groove (K) position, the dead bolt stops at that position while protruding. .. When unlocking, align the character arrangement of the locks and slide the moving body to the upper part to retract the dead bolt part and unlock it.

The movable body storage cover portion (D) is provided on the front surface side of the door, and the electric circuit changeover switch (a) is attached to the upper portion of the storage portion so as to come into contact with the movable body upper contact portion. The switch can be turned on at the same time as is stored, and the lighting in the room can be turned on. Also, if it is pulled out from the storage unit, the switch will come off and the light will go out. By using the switch for stairs, it can be turned on and off from two places, the room and the door. Furthermore, the storage cover can be detachably mounted from the inside of the door with a screw (c), etc., and the movable body can be taken out from the track body by removing the cover. If the upper half of the guide track body is thinner than the lower half, the moving body can be attached and detached because it can be removed from the part where it is sandwiched. By rearranging the character arrangement of the locks or replacing the locks, it is possible to set the unlock number freely and use it secretly. When unlocking, attach a thin plate (h) to the handle of the moving body to protect the inside of the lock from the sliding window and slide it along the outer frame of the lock.

A circular orbit-shaped guide groove (D) is provided on the inner surface of the door, and a forked handle (A) joined to the lock body (A) is attached to the door, and the guide body slides freely by rotation of the lock body. I will do it. The handle slides freely in the guide groove, but if it fits in the recessed part (si) provided on the upper part of the guide groove, one piece of the handle will support the groove edge and the rotation of the locking body will stop. If it is removed, the lock body will move again, and if it is sandwiched in the lower recess (s), the lock body will stop while protruding, so that the door can be locked from the inside as well as a single lock. Function. At this time, the movable body lock portion on the front side is housed inside the housing cover, and the meshing portion of the gear is disengaged.

The character ring (f) of the slide type character matching lock to be mounted is cut by cutting out the corners and sides of the character surface according to each character number to make uneven shapes, or by applying luminous paint etc. The sequence number of the unlocked position can be confirmed even in the dark.
