[0001] Inner Handle for Doorlock System [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inner handle for a door lock device used in a digital door lock device, which is a kind of locking device, and more particularly to an inner handle for a door lock device, To an outside handle for the door lock device.

A door lock device is a device that literally locks a door. In recent years, digital door locks have been used extensively in entrance doors of general households, office buildings, and offices due to the improvement of living standards. Digital door locks have a security function as compared to general digital door lock devices that can be locked or opened with a key only. Examples of security measures include a password input device, a fingerprint input device, and a card reader.

Such digital door locks are generally composed of an outdoor unit that is coupled to the outdoor side of the door and an indoor unit that is coupled to the indoor side of the door, each of which includes an outer handle and an inner handle. In such a digital door lock device, a deadlock (also referred to as a dead bolt) is generally used as a locking means. When a button or an internal handle is manipulated indoors or the security means is released from the outside, the deadlock retracts toward the door, So that the lock is released. In general, the deadlock is connected to the deadlock axis and is rotated forward or backward by the rotation of the key or the rotation means such as a motor to rotate the deadlock axis.

In using such a door lock device, there is a problem that when a user who has a poor judgment ability such as a child, a dementia patient, or a mental retarded person turns the inner handle and opens the door to the outside, a safety accident may occur or disappear. Most digital door locks will automatically lock when the door is closed, but users with poor judgment will not be able to unlock the door, so that they can not come out of the door after carelessly entering the door. Furthermore, in recent years, a digital door lock having a so-called panic function, in which a lock is automatically released without releasing a door lock through a separate operation when an internal handle is turned, is generally performed, and such a problem is becoming more serious.

Moreover, after the hole is drilled in the front door, a rod or the like is inserted through the hole to open the door to open the door to enter the inside, and even if the internal handle is operated, the door lock device is not unlocked There is a growing need.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a door locking device for locking a door lock device in a case where an inner handle is manipulated so as to prevent a user with poor judgment ability from going out of the door due to carelessness, So as to prevent the door from being released.

FIG. 1 is an exploded perspective view of an inner handle for a door lock apparatus according to one embodiment of the present invention, FIG. 2 is a sectional view of each configuration shown in FIG. 1, FIG. 3 is a view showing a state in which a coupler is in a first position, FIG. 4 is a view showing a state where the coupler is in the second position, and FIG. 5 is a view for explaining the connection between the door handle and the inner handle for the door lock apparatus shown in FIG.

The inner handle for the door lock device according to the present embodiment is installed inside the door lock device 1 and is used for opening the door.

The inner handle for a door lock apparatus according to the present embodiment includes a handle 10, a coupler 20, a movable member 30, a rod 40, and an elastic piece 50.

The handle 10 is composed of a shaft portion 11 and a pressing portion 12. Since the shaft portion 11 and the pressing portion 12 are coupled to each other, there is no particular meaning to distinguish the boundaries clearly. 1, the handle 13 is provided with a cover 13, which can be seen to include both the shaft 11 and the pressing portion 12.

In the shaft portion 11, a through hole (14) is provided in the shaft portion as a rotating shaft when the handle is operated to open the door for opening the door.

One end of the through-hole 14 is coupled with the door lock device 1 and the other end is exposed toward the inside of the door, and is formed long in one direction. In FIG. 1, the lower portion is a portion that engages with the door lock device 1, and the upper portion is the inner side of the door.

As shown in FIG. 2, a protrusion 15 protruding toward the inside of the through-hole 14 is provided at an end of the through-hole 14 on the side of the door lock device 1. As shown in FIG. In the present embodiment, four protrusions 15 are formed. In Fig. 2, a single protrusion 15 and two protrusions cut in half are shown, but another protrusion is formed on the opposite side of the intact protrusion, This projection is fastened to the groove 21 shown in Fig.

The pressing portion 12 is a portion which exerts a force when operating the handle 10. Generally, when a user applies a force to the pressing portion 12, the shaft 11 is rotated to apply a force to the door lock device 1, thereby causing the door lock device 1 to be unlocked.

The coupler 20 is accommodated in the through hole 14 so as to be movable in the longitudinal direction of the through hole 14 of the shaft portion 11.

As shown in FIG. 1, the coupler 20 is formed with a groove 21 which can be fastened to a protrusion 15 formed in the through hole 14. Inside the coupler 20, A long receiving groove 24 is provided.

The coupler 20 is moved between a first position and a second position within the through hole 14, the first position being such that the coupler 20 moves toward the door lock device 1 as shown in FIG. 3, The groove 21 of the coupler 20 is fastened to the protrusion 15 and the second position is such that the coupler 20 moves to the opposite side of the door lock device 1 as shown in FIG. The fastening of the groove 21 is released.

The shifting member 30 engages the handle 10 as a configuration for moving the coupler 20 from the first position to the second position. The first projecting piece 22 is formed on the opposite end of the end of the coupler 20 on which the groove 21 is provided and the movable member 30 can be fastened to the first projecting piece 22 A second projecting piece 31 is formed

The rod 40 is configured to transmit the motion of the handle 10 to the door lock device 1, one end of which is inserted into the rod hole 2 of the door lock device 1 shown in Fig. 5, (20) and rotates together with the coupler (20). The rod 40 is received in the receiving groove 24 of the coupler 40 and is a one-way long rod having a rectangular cross section as shown in Figs.

The elastic piece 50 is an iron plate bent as shown in FIG. 1 to elastically press the moving member 30 so that the coupler 20 can maintain the first position or the second position.

A mechanism in which the force applied to the handle 10 is not transmitted or transmitted by the rotation of the rod 40 when the coupler 20 is located at the first position and the second position, 20 to the first position and the second position, respectively.

3, when the movable member 30 is in the first position, the groove 21 of the coupler 20 is fastened to the projection 15 in the through hole 14 of the handle 10 When a force is applied to the pressing portion 12, the shaft portion 11 rotates. At this time, the rod 40 also rotates together to release the lock of the door lock device 1. [

In this state, when the movable member 30 is moved to the opposite side of the door lock apparatus, the movable member 30 moves while elastically deforming the elastic piece 50. After the movement is completed, the movable member 30 moves to the second position as shown in FIG. do. The moving member 30 and the coupler 20 are provided with the first protruding piece 22 and the second protruding piece 31 and are fastened to each other so that the coupler 20 moves when the moving member 30 is moved.

The coupling between the groove 21 of the coupler 20 and the projection 15 of the handle 10 is released so that the pressing portion 12 is urged to rotate the shaft portion 11, The rotation of the coupler 20 is not transmitted to the coupler 20. Therefore, when the coupler 20 is in the second position, the lock state of the door lock device is maintained even if the user inside the door turns the handle 10. [ Therefore, it is possible for a person with low judgment ability such as a person with a physical disability or a dementia to go out of the door to prevent an accident that may occur.

In order to move the coupler 20 from the second position to the first position to open the door, a force is applied to the end portion 23 of the cover 13 opposite to the door lock apparatus 1. In this embodiment, 2, the end portion 23 of the coupler 20 opposite to the door lock device is projected out of the cover 13 of the handle 10 so that the force can be easily applied. When a force is applied to the coupler 20, the coupler 20 moves to the first position while elastically deforming the elastic piece 50 again.

The resilient piece 50 resiliently urges the coupler 20 so that it can maintain its position when the coupler 20 is in the first position or the second position. Since the elastic piece 50 must be elastically pressed to move the coupler 20, the user can feel that the elastic force of the elastic piece 50 is hand-transmitted through the coupler 20, And the effect of temporarily fixing the position of the coupler 20 can be expected more reliably.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It can be embodied as an internal handle for various types of door lock devices.
