Mortis spacer for door lock system {SPACER FOR MORTISE OF DOOR-LOCK SYSTEM}

The present invention relates to a door lock system installed in the door, and more particularly to a spacer for the mortise of the door lock system that can be more stably mounted mortis inside the door.

In general, the door lock is a manual locking device that is manually opened and closed using a key is widely known. However, in such a manual locking device must be opened and closed only if you have a key, because of this, if you lose the key there is an inconvenience in use to open the locking device to contact a separate service center.

Recently, in order to alleviate the inconvenience of the manual locking device, a digital door lock system is disclosed that automatically opens and closes the door by inputting a password through a button of an input unit installed outside the door or by inputting a fingerprint into a fingerprint recognition device installed outside the door. It is.

The conventional digital door lock system is provided on the inside and the outside of the door and has an inner and outer body provided with door handles, respectively, and a mortis disposed between the inner and outer bodies. In addition, the mortise is disposed inside the door between the inner body and the outer body, and is provided with a dead bolt and a latch that operates in conjunction with the respective door handle to perform the locking or unlocking operation of the door.

On the other hand, the door to which the mortis is mounted is usually made in a variety of thickness of 40 ~ 60mm. In addition, in consideration of the thickness of the iron plate of the door 2 ~ 3mm, the interior thickness of the door in which the mortis is built is varied to about 34 ~ 54mm. And the thickness of the mortise that is mounted inside the door of various thicknesses (about 34 to 54 mm) is usually about 20 mm.

Therefore, conventionally, as shown in FIGS. 1 and 2, in order to compensate the free space in the process of inserting the mortise 1 into the door 2, the synthetic resin bracket 3 is mounted on the rear part of the mortise 1. It was. The synthetic resin bracket 3 is composed of a square plate 3a having a plurality of ribs and a pair of semi-circle plate portions 3b and 3c integrally formed in a direction orthogonal to both ends of the square plate 3a. A space portion 3d is formed between the semi-circular plate portions 3a and 3c of the pair by which the mortise 1 is fitted.

That is, when the rear of the mortise 1 is inserted into the space portion 3d of the synthetic resin bracket 3 and then continuously inserted into the door 2, the mortise 1 is opened by the synthetic resin bracket 3. It is solidly assembled inside.

However, in the structure of the synthetic resin bracket 3 of the conventional mortise (1), since its thickness (T) is manufactured in a single size, there is a limit to satisfy all of its functions in the door (2) having a variety of thickness. Due to this, the mortise 1 slightly flows from side to side inside the door 2, and in severe cases, the assembling posture of the mortise 1 is distorted, causing a load on the locking and releasing operation, which causes a decrease in product reliability.

The present invention is to solve this problem, an object of the present invention is to provide a spacer for the mortise of the door lock system that can be more stably assembled at various space thicknesses inside the door in the process of inserting the mortis into the space formed inside the door. will be.
