Description

Electronic Door Lock Device for Easy Installation {A Door Lock Device}

The present invention relates to an electronic door locking device, and more particularly, to an electronic door locking device capable of locking and opening the door by simply replacing the door handle without requiring the installation of the Mortis.

There are two general types of door locks (including electronic door locks) that are commonly mounted on doors. One is a handle integral door lock that the clasp is operated by the handle of the door, the other is an auxiliary door lock that the clasp is operated by a separate key or an external signal irrespective of the operation of the handle of the door.

In such a door lock, the latter auxiliary door lock can be installed separately from the handle-integrated door lock device already installed in the door, there is an advantage that does not need to dismantle or change the pre-installed (integrated handle) door lock. However, these auxiliary door locks have to be drilled in the doors for electrical or mechanical communication between the bodies installed on the inside and outside of the doors. There is a limit to going or replacing it with another assisted door lock.

On the other hand, since the handle integrated door lock device generally utilizes a handle hole formed in the door, there is no need for a separate punching operation, and the door lock is operated by the handle of the door, so that the appearance of the door is rough. There is also an advantage that does not go away. However, such a handle integrated door lock device requires a mortise that is installed inside the door, so the installation work is very cumbersome and complicated. In addition, the one-piece door lock works in conjunction with Mortis, so if you replace an existing lock with a new type (for example, from a mechanical lock to an electronic lock or another manufacturer with a different lock) In case of replacement), there is a need to replace all parts including the mortis and the handle, and accordingly, there is a disadvantage in that excessive replacement costs are required.

The present invention is intended to compensate for the disadvantages of the conventional door locks as described above, the purpose is to provide an electronic door lock that can be operated by the handle of the door as well as not having a relatively inconvenient mortis.

According to an embodiment of the present invention for achieving the above object, a first handle having a shaft, rotatably installed in the entrance door about the shaft; A second handle rotatably installed at the door; A first body provided on the first surface of the door and having a latch provided to be operated by rotation of the shaft; A clutch bundle for selectively connecting and disconnecting the shaft and the second handle; And a second body mounted on a second surface of the door and having driving means for manipulating the clutch bundle in accordance with an authentication signal of the authentication signal input unit and the authentication signal input unit, wherein the clutch bundle comprises: the second handle; A housing coupled and having an opening therein open toward the first handle; A first connection member installed in the hole, coupled to the shaft, and having a protrusion at an end thereof; A second connection member installed in the hole so as to be integrally rotated with the housing, and having a groove formed at an end thereof to engage with the protrusion, and moving along the longitudinal direction of the housing and selectively connected to the first connection member; It is rotatably installed around the housing, and selectively rotates according to the operation of the driving means, and by moving the second connecting member in the longitudinal direction of the housing, the first connecting member and the second connecting member A pair of pressing members for selectively connecting the; And an elastic member installed in the housing to push the second connecting member or to rotate the pair of pressing members so that the first connecting member and the second connecting member are separated from each other. An easy electronic door lock is provided.

Preferably, the second handle comprises: a cylinder bundle having a key hole and rotated during key operation; Wedge-shaped cam member coupled to the cylinder bundle; And a third connecting member installed to be movable along the longitudinal direction of the housing, one end of which is formed to correspond to the cam member to selectively push the second connecting member according to whether the cylinder bundle is rotated. Good to do.

The present invention has a structure that allows the locking operation and the opening operation of the door lock without a mortis, it is easy to install and replace the device.

In addition, the present invention has a structure in which the inner handle shaft and the outer handle shaft can be connected to each other irrespective of the rotation position of the handle, each spring needs a spring structure and a spring member for returning or rotating the handle to the original position none. Therefore, according to the present invention, the overall structure of the door locking device can be simplified and miniaturization can be easily achieved.

In addition, the present invention is because the binding and separation of the inner handle shaft and the outer handle shaft is made mechanically by the motor, it is relatively strong to the external electric or magnetic impact, it is possible to significantly reduce the occurrence of malfunction due to such impact. .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, terms referring to the components of the present invention are named in consideration of the function of each component, it should not be understood as a meaning limiting the technical components of the present invention.

1 is a cross-sectional view of a main part showing a schematic configuration of an easy electronic door lock according to a preferred embodiment of the present invention, Figure 2 is an exploded perspective view of the clutch bundle shown in Figure 1, Figure 3 is in Figure 1 4 is an exploded perspective view of the second handle, and FIGS. 4 and 5 are state diagrams for explaining the operation principle of the electronic door lock shown in FIG.

Electronic door locking device 10 according to the present invention is a structure that can easily install the respective components through the handle installation hole 102 of the door 100, without installing a mortis on the inside of the door 100, It includes a first handle 20, the second handle 30, the first body 40, the second body 50, the clutch bundle 60.

The first handle 20 is rotatably installed on the inner side (ie, the interior side) of the door 100, and has a shaft 22 installed inward through the hole 102 of the door 100. The shaft 22 is connected to the clutch bundle 60, and is also mechanically connected to the latch bundle 42 provided in the first body 40. Therefore, when the first handle 20 is rotated, the latch 42 of the first body 40 is manipulated to change the locked state of the door 100 to the open state.

The second handle 30 is rotatably installed on the outer side (ie, the outdoor side) of the door 100 and is coupled to some member (exactly the housing 62) of the clutch bundle 60, the corresponding member ( That is, it rotates integrally with the housing 62. Accordingly, when the user turns the second handle 30 on the outside of the door 100, the housing 62 is rotated together with the second handle 30. On the other hand, the second handle 30 is provided with a number of members including a cylinder bunch 34 that can operate the clutch bunch 60 by a key operation.

As shown in FIG. 3, the internal structure of the second handle 30 includes a cylinder bundle 34, a cam member 36, and a third connecting member 38. The cylinder bunch 34 is installed in the second handle 30. The cylinder bundle 34 or the shaft 342 of the cylinder bundle 34 is rotated by the operation of the correct key 200. Since the configuration of the cylinder bunch 34 for key operation is a known technique, detailed description thereof will be omitted. The cam member 36 is configured to change the linear motion of the third connecting member 38 by rotation by the cylinder bundle 34, and includes a fixing pin 362, a bushing 364, and a half-moon-shaped protrusion 366. . The cam member 36 thus formed is rotated together with the shaft 342. One end of the third connection member 38 is fitted into the hole 628 of the housing 62 of the clutch bundle 60, and the other end thereof is installed to contact the protrusion 366. The third connection member 38 has a half-moon-like protrusion at the other end thereof, such as the protrusion 366, and moves inside the housing 62 when the protrusion 366 is rotated. For reference, in the present embodiment, the cam member 36 is separated into three members, but the rotation by the shaft 342 of the cylinder bundle 34 may be changed by the linear movement of the third connecting member 38. It can be changed to one member having a formed shape.

The first body 40 is installed on the inside of the door 100, and has a clasp 42 to enable the lock setting of the door 100. Clasp 42 includes a clasp that protrudes into a door frame or other fastener and a mechanical device that enables the clasp to be manipulated. In addition, the clasp 42 is mechanically connected to the first handle 20 or the shaft 22 of the first handle 20, it is operated when the first handle 20 is rotated. For reference, the structure of the clasp 42 and the connection structure of the clasp 42 and the shaft 22 can be easily implemented by those skilled in the art to which the present invention pertains, through known techniques. Detailed description thereof will be omitted.

The second body 50 is installed outside the door 100 and includes an authentication signal input unit 52 and a driving means 54. The authentication signal input unit 52 includes a plurality of buttons for inputting an authentication signal and is electrically connected to the driving means 54. The authentication signal input unit 52 transmits an electric signal for driving the driving means 54 when the correct authentication signal is input through the button. The driving means 54 operates according to the electrical signal of the authentication signal input 52, and operates the clutch bundle 60 so that the shaft 22 and the second handle 30 are connected during operation.

As shown in FIG. 2, the clutch bundle 60 includes a housing 62, a first connecting member 64, a second connecting member 66, a pressing member 68, and an elastic member 69.

The housing 62 is generally cylindrical in shape and has a support 622 for installing a pair of pressing members 68 and a hole 626 having a square cross section for installation of the connecting members 64, 66. do. Supports 622 are formed on the circumferential surface of the housing 62, respectively, and the holes 626 face the longitudinal direction of the housing 62 at one side of the housing 62 (the side facing the first handle 20). It is formed long along. A through hole 624 is formed in the circumferential side of the housing 62 (the lower side in FIG. 2) to communicate with the inside of the housing 62 (ie, the hole 626).

The first connecting member 64 is a member having a generally elongated axial shape, which serves as a connection between the shaft 22 of the first handle 20 and the clutch bundle 60. One end of the first connecting member 64 is coupled to the shaft 22 in a thin rod shape, and the other end is fitted into the hole 626 of the housing 62 in a substantially cylindrical shape. Since the other end of the cylindrical first connecting member 64 has a circular cross section having a diameter equal to the width of the hole 626, it can be rotated in contact with the inner wall of the hole 626. On the other hand, the other end of the first connecting member 64 is formed with a projection (642) for binding with the second connecting member (66).

The second connecting member 66 has a generally hexahedral shape fitted to the hole 626 of the housing 62, and is installed in the hole 626 of the housing 62 so as to be movable in the longitudinal direction of the housing 62. . A groove 662 is formed at one end of the second connecting member 66 to engage with the protrusion 642 of the first connecting member 64, and a protrusion of the pressing member 68 is formed at a side surface (downward based on FIG. 2). An insertion hole 664 into which the 684 is fitted is formed. The second connecting member 66 formed as described above is rotated integrally with the housing 62, moves back and forth along the longitudinal direction of the housing 62, and is selectively engaged with the first connecting member 64.

The pair of pressing members 68 are generally bow-shaped and curved to form a ring in the installed state of the housing 62 so that they can be pressed in any radial direction of the housing 62 (ie, the present invention). Since the pressing members 68 are installed to surround the housing 62, the pressing members 68 may be pressed by the driving means 54 even when the housing 62 is rotated when the housing 62 is installed. Each pressing member 68 has a branch portion 682 protruding from the middle of the curved body to the center of the virtual circle formed by the curved body. The branch portion 682 is fitted and fixed to the support 622 of the housing 62 so that the pressing member 68 can be rotated about an axis formed in the support 622. Meanwhile, one of the pair of pressing members 68 (in this embodiment, installed below the housing 62) is inserted into the second connecting member 66 through the through hole 624 of the housing 62. It has a protrusion 684 that fits into the ball 664. The protrusion 684 may be formed in an extended form of the branch portion 682. As described above, the pair of pressing members 68 installed in the housing 62 move the second connecting member 66 in the rotational direction, and serve as an excuse for engaging or separating the first connecting member 64.

The elastic member 69 is installed between the housing 62 and the pressing member 68 to move the pair of pressing members 68 in one direction (a direction in which the pair of pressing members 68 are far from each other, or FIG. 1 serves as a reference to rotate the projection 684 in a direction that rotates counterclockwise. Therefore, when no external force (pressing by the driving means 54) is applied to the pair of pressing members 68, the pressing members 68 are maintained by the elastic member 69 in the state shown in FIG. do. In this case, the second connecting member 66 is separated from the first connecting member 64 by the protrusion 684 of the pressing member 68.

Next, the operation principle of the present invention configured as described above will be described based on FIGS. 2 to 5.

The door locking device 10 according to the present invention is such that the clasp 42 mechanically connected to the shaft 22 of the first handle 20 can not be operated by turning the second handle 30 from the outside in normal times. , The connection of the first handle 20 and the second handle 30 is maintained in a separated state by the clutch bundle (60). That is, the first connecting member 64 and the second connecting member 66 located inside the housing 62 of the clutch bundle 60 are separated by the pressing member 68 as shown in FIG. 1. maintain.

In this state, when the authentication signal is input through the authentication signal input unit 52, the driving means 54 is operated (that is, the rod of the driving means 54 is pushed downward), the pair of pressing members 68 Press at least one of Then, with the rotation of the pressing member 68, the protrusion 684 rotates in the time direction (the reference direction of FIG. 1) while the second connecting member 66 and the first connecting member 64 are rotated as shown in FIG. Are interlocked (see FIG. 2 for a detailed configuration of the reference numerals). Since the engagement between the connecting members 64 and 66 permits the transmission of the rotational force by the second handle 30 to the first handle 20, when the user turns the second handle 30, the first handle 20 is rotated. The clasp 42 connected with is operated to release the locked state of the door.

On the other hand, when the user operates the key 200 in the state shown in Figure 1, the cylinder bundle 34 or the shaft 342 of the cylinder bundle 34 is rotated. Then, as shown in FIG. 5, the cam member 36 pushes the third connecting member 38 into the housing 62 by the rotation of the shaft 342, and thus the third connecting member 38. The second connecting member 66 is pushed toward the first connecting member 64 so that the second connecting member 66 and the first connecting member 64 mesh with each other (see FIG. 2 for a detailed configuration of the reference numerals). ). Since the engagement between the connecting members 64 and 66 allows the transfer of the rotational force by the second handle 30 to the first handle 20 as described above, when the user turns the second handle 30, The latch 42 connected to the handle 20 is operated to release the locked state of the door.

The present invention made as described above has a structure in which the first handle and the second handle are connected by a key operation and an authentication signal input, and thus do not require a mortis and facilitate the installation of a door.

In addition, the present invention can be installed in any form as long as the door with a handle hole, so that the door is not unnecessarily damaged when replacing the locking device due to moving or breakdown.

The present invention is not limited only to the embodiments described above, and those skilled in the art to which the present invention pertains as long as they do not depart from the spirit of the technical idea of the present invention described in the claims below. Various changes can be made.
