Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a sliding door lock. More specifically, the present invention relates to a sliding door lock that can be easily and reliably attached and adjusted to doors, sashes, etc.

[Prior art and its problems] Sliding door locks are widely used by being attached to the center stile of aluminum sliding doors in entrances, or to aluminum sashes. From the outside, this sliding door lock works by inserting the key into the keyhole of the external lock and rotating it, the gear inside the internal lock moves the rack, and the movement of the rack moves the upper sickle and lower sickle to lock the door. . Unlocking is done by rotating the key in the opposite direction. Also, from the inside, the door can be locked or unlocked by lowering or raising the sliding knob.

Sliding door locks operate as described above, but if the external lock and internal lock are not properly installed or adjusted, the hub guide of the external lock and the hub guide hole of the internal lock may not align. There were problems such as the key becoming difficult to move, and the upper and lower sickles of the internal lock not fully engaging with the through holes of the external lock, resulting in the door opening even when you thought it was locked.

The present invention eliminates the insufficiency of installation and adjustment between the external lock and the internal lock, and ensures that the hub guide of the external lock and the hub guide hole of the internal lock always match.
Another object of the present invention is to provide a sliding door lock in which the upper and lower sickles of the internal lock completely engage with the through holes of the external lock.

[Means for Solving the Problems] In order to solve the above problems and achieve the purpose of the invention, the present invention is characterized by the following configuration. That is, in a sliding door lock consisting of an internal lock and an external lock, the internal lock has two sets of adjustment holes penetrating the decorative plate and front plate of the internal lock, and the receiving holes corresponding to the adjustment holes are formed in the external lock. It consists of an external lock formed on the rear plate and two set pins that can be inserted into and removed from the adjustment hole and the receiving hole, and is characterized in that it can be easily and reliably installed and adjusted.

[Example] The following will be described in detail using examples shown in the drawings.

The internal lock 1 includes an internal lock decorative plate 11 and an internal lock plate 1.
The lock body is placed between the two. Two sets of adjustment holes are formed in the internal lock, passing through the decorative plate 11 and front plate 12 of the internal lock. That is, an adjustment hole 13 is provided in the upper part of the internal lock decorative plate 11, an adjustment hole 14 is provided in the lower part of the internal lock decorative plate 11, and an internal lock plate 12 is provided in the lower part of the internal lock decorative plate 11.
An adjustment hole 15 is formed in the upper part of the internal lock plate 12, and an adjustment hole 16 is formed in the lower part of the internal lock plate 12. Further, a receiving hole corresponding to the adjustment hole is formed in the rear plate 22 of the external lock. That is, a receiving hole 23 is provided in the upper part of the external lock rear plate 22, and a receiving hole 24 is provided in the lower part of the external lock rear plate 22.
is formed. Here, the decorative plate 11 of the internal lock
A set pin 31 is installed in a set of adjustment holes 13 and 15 passing through the front plate 12 and a set pin 31 in the receiving hole 23 of the rear plate 22 of the external lock. The set pin 32 can be inserted into the adjustment hole 14, the adjustment hole 16, and the receiving hole 24 of the external lock rear plate 22, and can be removed. A steel wire with a diameter of about 2 mm is suitable for the set pin.

Since the present invention is constructed as described above, the sliding door lock is installed and adjusted as follows. The installation and adjustment of the sliding door lock will be explained below with reference to FIG. First, the external lock 2 is attached to the outer door 7, etc., and then the internal lock 1 is attached to the inner door 6, etc. Gently loosen the inner mounting screws 4, 4 of the internal lock 1 with a screwdriver, insert the set pins 31, 32 (2 pieces) into the adjustment holes 13, 14 of the internal lock decorative plate 11, and then
Adjust left and right, confirm that the set pins 31, 32 have entered the receiving holes 23, 24 of the external lock rear plate 22, tighten the mounting screws 4, 4, and then remove the set pins 31, 32.
