Description

A handle-fixed door lock device for unlocking structure of the latch bolt}

The present invention relates to a handle-fixed door lock device capable of opening a door by releasing a locked state of a latch bolt without electrical driving under the condition that the dead bolt is unlocked.

A door lock device is a device that can unlock a door through key input or biometric information, even if the user does not have a key, and automatically locks the door when it is closed. Its demand is steadily increasing.

Such a door lock device includes a mortise installed inside a door and performing a locking function to control indoor and outdoor access, and a handle (lever) installed inside and outside the door to operate the mortise. Further, the mortis includes a latch bolt operated by an indoor/outdoor handle, a dead bolt that maintains a door lock, and a driving means for operating the dead bolt. To open the door, perform authentication using a mechanical key, password input, biometric information, etc., unlock the dead bolt, and then unlock the latch bolt by manipulating the handle. A configuration for controlling the dead bolt and latch bolt of the door lock device is known in many prior documents, including Korea Utility Model Registration No. 20-0418866 (dead bolt and latch bolt control device of digital door lock).

As described above, various types of door lock devices have been developed in addition to a structure in which a door is opened by unlocking a latch bolt by rotating a handle. For example, a structure in which a latch bolt is unlocked by operating the handle in a push or pull manner without rotating the handle, or a door lock structure in which the handle is fixed may be referred to. Among them, the handle-fixed door lock device can generally have a more elegant design than a handle rotation method or a push-pull method, and can also eliminate inconvenience caused by handle operation.

The handle-fixed door lock device has a motor module inside the door, and when authenticated as a legitimate user using a password, card, and biometric information, the dead bolt and latch bolt are simultaneously driven by the motor driving force according to the control operation of the control board. unlock it by As in the prior art, the door can be opened and entered by pushing or pulling the door without a separate handle operation.

However, in the handle-fixed door lock device, the door may need to be opened by manipulating only the latch bolt while the dead bolt is always unlocked, if necessary. Since the dead bolt is unlocked, the user only needs to unlock the latch bolt. In this case, unlocking of the latch bolt is performed by battery power. Therefore, when there is no battery power (for example, when the battery is discharged), there is no way to substantially open the door in which the handle-fixed door lock device is installed. Of course, there are methods using emergency power, etc., but there is the hassle of having a battery

Accordingly, an object of the present invention is to solve the above problems, in a handle-fixed door lock device in which the dead bolt is unlocked, the handle for unlocking the latch bolt to manually unlock the latch bolt. It is to provide a fixed door lock device.

Handle-fixed door lock device for unlocking the latch bolt of the present invention for achieving the above object, the outer body installed on the outside of the door; Inbody installed inside the door; and a mortise embedded in the door and having a dead bolt and a latch bolt, wherein the outer body includes: a main body; a pressing part protruding from the main body; a locking groove located inside the main body and formed at an end of the pressing part; a rotation lever rotatably coupled to the seat on the inner surface of the main body and having a protrusion inserted into the locking groove and a shaft coupling hole formed in a direction orthogonal to the protrusion; And it is characterized in that it is configured to include a shaft coupled to the shaft coupling hole and the other end connected to the latch bolt of the mortise.

When the pressing unit is pressed, the rotary lever rotates in one direction about the rotary shaft, and the shaft rotates according to the rotation of the rotary lever to unlock the latch bolt.

An elastic means for returning to an initial state after the pressing operation of the pressing unit is further included.

According to the handle-fixed door lock device for unlocking the latch bolt of the present invention as described above, a separate configuration for unlocking the latch bolt is added to the outer body of the door lock device. Accordingly, in an environment where the dead bolt is unlocked, when unlocking the latch bolt, the operator can easily unlock the latch bolt through a series of manipulations without a separate user authentication means. This can improve the working environment.

Since the configuration for unlocking the latch bolt is activated only under conditions such as battery discharge, indiscriminate unlocking of the latch bolt can be prevented.

Objects and effects of the present invention, and technical configurations for achieving them will become clear with reference to embodiments described later in detail in conjunction with the accompanying drawings. In describing the present invention, if it is determined that a detailed description of a known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or operator.

However, the present invention is not limited to the embodiments disclosed below and may be implemented in a variety of different forms. Only these embodiments are provided to complete the disclosure of the present invention and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined by the scope of the claims. It only becomes. Therefore, the definition should be made based on the contents throughout this specification.

The present invention is a configuration for manually unlocking a latch bolt in a handle-fixed door lock device. A general digital door lock device has a rotatable handle, whereas a handle fixed type door lock device has a structure in which a handle that can be operated by a user is fixed. This handle-fixed door lock device simultaneously unlocks the dead bolt and the latch bolt according to the control operation of the control board after the authentication procedure. It is proposed to release the structure.

Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings.

1A and 1B are front/rear separated perspective views of a handle-fixed door lock device according to an embodiment of the present invention. As shown in the drawing, a handle-fixed door lock device (also called a digital door lock or a door lock device) (1) includes an outbody 10 installed on the outside of the door, an inbody 20 installed on the inside of the door, and It is built into the door and has a mortise 30 having a dead bolt and a latch bolt. In addition, the outer body 10 is provided with components for inputting a keypad, card, or fingerprint as a means for authenticating a visitor.

As shown in Figure 1, the handle-fixed door lock device of the present invention does not have a handle for rotation or push-pull driving in the outbody 10 and the inbody 20. Only the handle in a fixed form that the user can grip is integrally molded with the body body. That is, the handle of the present invention is not used for operating a dead bolt or latch bolt, but is used only for pushing or pulling a door.

In addition, a control board and a battery for supplying power are mounted on the inbody 20 . The dead bolt or latch bolt moves according to the control operation of the control board in a situation where power is normally applied to the door lock device.

The present invention may be applied to a condition in which a dead bolt is always in an unlocked state and a door is opened and closed only with a latch bolt. For example, when construction for an apartment or officetel is in progress, the dead bolt is unlocked for convenience of work, and the door is often opened and closed only with the latch bolt.

In this case, if the battery power is normal, the operator can unlock the latch bolt through a pre-assigned authentication procedure. On the other hand, if there is no battery power, the operation of the latch bolt is impossible. Alternatively, it may be applied even when the battery is not installed. To this end, a structure for unlocking the latch bolt is proposed, and see FIGS. 2 and 3 .

2 is a combined perspective view of a handle-fixed door lock device according to an embodiment of the present invention, and FIG. 3 is an exploded perspective view. Here, FIGS. 2 and 3 show an example in which a structure for manually releasing the latch bolt is provided on the outer body of the door lock device.

As shown. The pressing part 100 is installed so that a part protrudes from the main body 11 of the outer body 10. The pressing unit 100 includes a first region 110 in which a contact surface having a certain area is formed so that a user can easily perform a pressing operation, and a second region extending from the first region 110 in one direction (ie, inside the outer body). It includes 2 regions (120). The first region 110 and the second region 120 may be integrally formed or may be separately formed and then combined.

An engaging groove 122 is formed at the end of the second region 120 . The locking groove 122 is a portion into which the locking protrusion 210 below is inserted and coupled. The locking groove 122 is formed in a long shape in the vertical direction. In addition, an inclined surface 130 is formed between the first area 110 and the locking groove 122 . The first region 110 is low and the region where the locking groove 122 of the second region 120 is formed is high. Therefore, it is only necessary to form a cutout in the body 11 of the outbody 10 by the size of only the first region 110 .

A rotary lever 200 interlocking with the pressing part 100 is provided. The rotary lever 200 is coupled to the seating portion 300 formed on the lower side. Here, the seating portion 300 is a structure formed on the inner surface of the outbody 10 . The rotation lever 200 coupled to the seating portion 300 is rotated in the axial direction according to the pressing action of the pressing portion 100 .

The rotary lever 200 is formed by including a locking protrusion 210 at a position corresponding to being inserted into the locking groove 122 and a shaft coupling hole 220 to which a shaft is coupled. The shaft coupled to the shaft coupling hole 220 is a shaft for a latch bolt and is connected to the latch bolt of the mortise 30 . The locked state of the latch bolt is released according to the rotation of the shaft.

An elastic means 400 is provided on one side of the pressing part 100 . The elastic means 400 is for returning the pressing part 100 to an initial position when the pressing force on the pressing part 100 is released, and may be, for example, an elastic spring. The elastic spring 400 is mounted on a separate bracket as shown in the drawing and is installed on the side of the pressing unit 100, and returns to its original position when the pressing is released.

4 is a diagram of an embodiment in which the pressing unit 100 is provided on the outer body 10. All existing door lock devices do not have such a structure of the pressing unit 100 at all. According to this embodiment, the pressing unit 100 does not need to be used in a state where battery power is normally applied. Therefore, the pressing operation of the pressing unit 100 is not performed in the battery power supply state, and the pressing operation of the pressing unit 100 is possible only in the battery discharge state.

Next, a process of unlocking the latch bolt by pressing the pressing unit 100 in the handle-fixed door lock device of the present invention configured as described above will be described.

5 is an exemplary diagram illustrating a process of unlocking a latch bolt according to a pressing operation of the pressing unit 100 . Referring to FIG. 5 , when the pressing unit 100 is pressed in the direction of the arrow, the outer body 10 moves inside.

Then, since the locking protrusion 210 is inserted into the locking groove 122 and coupled thereto, the rotary lever 200 rotates at a predetermined angle in a counterclockwise direction. The rotation range corresponds to the amount of horizontal movement of the pressing unit 100 .

As such, when the rotary lever 200 rotates, the shaft coupled to the shaft coupling hole 220 also rotates. Accordingly, the locked state of the latch bolt connected to the shaft is released.

On the other hand, when the pressing force on the pressing part 100 is released after the locking state is released, the pressing part 100 returns to the initial position by the restoring force of the elastic spring 400, and thus the locking groove 122 and the locking protrusion ( 210), the rotary lever 200 also rotates in a clockwise direction to an initial position.

As described above, in the present invention, when the operator presses the pressing part configured on the outer body, the rotary lever and the shaft are rotated in association with the pressing part, and the latch bolt is unlocked. It can be seen that the present invention can easily unlock the latch bolt even if the battery is discharged in the handle fixed door lock device, rather than the handle rotation type or push-pull type door lock device for manipulating the conventional dead bolt or latch bolt.

Although the above has been described with reference to the illustrated embodiments of the present invention, these are only examples, and those skilled in the art to which the present invention belongs can variously It will be apparent that other embodiments that are variations, modifications and equivalents are possible. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
