Remote control electronic key box for door handle

专利摘要:
PURPOSE: An electronic remote control key box for a door handle is provided to transmit and receive an electric signal to/from a key box of a door hand and perform a remote controlling operation. CONSTITUTION: An electronic actuator(6) is located at an inside of a key box. The electronic actuator controls an open function according to an external electric signal. A locking arm(3) provides motions of a handle and the electronic actuator(6). A stopper(11) holds the locking arm(3). A locking block(2) performs a stable locking function. Rack and pinion gears(4,5) control motions of a latch bolt and the locking arm(3). A spring(9) provides easy operations of each part. A micro switch(8) generates and transmits an electronic signal to an external body to electronically confirm an open state and a locking state.

Remote control electronic key box for door handle}
[12] The present invention relates to a remote control electronic key box for a door handle, and more particularly, to a remote control for a door handle having an electronic actuator for remote control by transmitting and receiving an electric signal to a key box of a door handle attached to a building fire door. It relates to an electronic key box.
[13] In general, the fire door or the front door uses a key box having a mechanical structure built into the door together with a door handle with a key, which is operated only manually for the purpose of smoothly locking and opening the door. Recently, a digital door lock is used to have a locking and opening function, which consists of a key box of a mechanical structure manufactured separately according to a manufacturer's characteristics and a main body that processes an electrical signal.
[14] Conventionally, the only way to open and close the door is to select only a touch type operation in which an operator directly accesses the door to operate the door handle or manipulates a fingerprint or a button.
[15] Recently, however, with the development of the information and communication network, the home environment has become a home automation, but a key box capable of remote control is urgently needed. However, electric and remote control are impossible with a key box having a conventional mechanical structure. In addition, the digital door lock can be opened electrically, but remote control is not possible. Also, in the case of the digital door lock, it is inconvenient to develop a key box every time according to the manufacturer's characteristics. When the product is installed and removed after installation, there is a problem in that the fire door itself needs to be repaired since processing marks remain on the door.
[16] In order to solve the above problems, the present invention inserts an electronic actuator, a micro switch, and the like into a key box, thereby providing a remote control by transmitting an automatic opening function and a status signal of the key box to the outside by an electric signal received from the outside. By making it possible to implement home automation, as well as simplifying and sharing the components of the key box, it reduces the development period and economic burden for product development by manufacturer, and it is compatible with the conventional key box. It is an object of the present invention to avoid the need to reprocess fire doors for the installation of.
[17] In order to achieve the above object, the present invention, the electronic actuator located inside the key box for controlling the opening function by the electrical signal received from the outside, the locking arm for transmitting the movement of the handle and the electronic actuator, and locking the locking arm Stopper, locking block for secure locking function, latch bolt to simultaneously perform the function of latch bolt and dead bolt, rack and pinion gear to control the movement of latch bolt and locking arm, and smooth operation of each part. It is characterized by consisting of a micro switch for transmitting the electrical signal to the external body so that the spring, the open and locked state for electronically.

[18] Hereinafter, described in detail by the accompanying drawings as follows.
[19] Figure 2 is an internal structural view showing a coupling state of the present invention, a state that can normally open and close the door with the door handle.
[20] 3 shows a situation that occurs when the door is pushed and closed without using the door handle, and only the latch bolt 1 operates while the compression spring 9 coupled to the latch bolt 1 is compressed.
[21] 4 shows an open state by the operation of the door handle, and when the door handle is rotated upward, the rack gear 4 engaged with the pinion gear 5 reverses and opens.
[22] FIG. 5 illustrates a situation in which the locking operation is in progress. When the door handle is rotated downward, the pinion gear 5 presses a specific section of the locking arm 3, and the spring 6 of the electronic actuator moves the stopper 11. The locking arm 3 is pushed out to hold the locking arm 3 while the locking arm 3 pushes the micro switch 8 to send a locking signal to the outside. In addition, the locking block 2 is raised due to the rotation of the locking arm 3 to prevent the retraction of the latch bolt 1 to prevent the forcible opening from the outside. This is the case when one latch bolt performs the function of dead bolt at the same time.
[23] 6 represents a state in which the locking operation is completed and in the waiting state.
[24] The operation for releasing the locked state of the key box can be performed while the electronic actuator 6 receiving the predetermined electrical signal received from the outside is operated to return the stopper 11 holding the locking arm 3. The spring 10 connected to the locking arm 3 returns the locking arm 3 to the open state, and the locking arm 3 pulls down the locking block 2 to which the latching bolt 1 is connected. It will return to a state where it can operate smoothly.
[25] In order to release the locked state in case of an emergency such as a power failure, when the open block 7 is rotated by using a key from the outside, the stopper 11 is forced to retreat and the locking arm 3 is returned to the normally locked state. Becomes
[26] As described above, in the present invention, the electronic actuator and the micro switch are inserted into the key box so that the remote control is possible by transmitting the auto-opening function by the electric signal received from the outside and the status signal of the key box to the outside. This makes it easy to implement home automation and can simplify and share the components of the key box, reducing development time and economic burden for product development by manufacturer, and installing the product because it is compatible with the conventional key box. It can have the effect of not having to rework the fire doors.
