• the present invention relates to a door-lock apparatus, and more particularly, to a door-lock apparatus that can be installed without damaging a door and can also be installed at and removed from a door without disassembly thereof.
• a conventional door-lock apparatus generally comprises a body with an input unit such as a keypad, and an operating body with a movable latch. The body is mounted on an outer surface of a door, and the operating body is mounted on an inner surface of the door.
• the door on which the body and the operating body are mounted is formed with a through-hole such that the body and the operating body can be fixed to the door and the body and the operating body can be electrically connected to each other.
• the door-lock apparatus Upon installation of the door-lock apparatus, the door-lock apparatus is not simply assembled but requires the formation of the through-hole in the door. If a through-hole is formed at an incorrect position due to a mistake or an error upon initial installation of the door-lock apparatus, the incorrect through-hole remains in the door as it is. In a severer case, the door itself should be replaced. Thus, the installation of the door-lock apparatus should be entrusted to an expert. Since the formation of a through- hole is essential for such a conventional door-lock apparatus, a door is inevitably damaged.
• the door-lock apparatus when a person or family moves to another house, the door-lock apparatus should be dissembled by unfastening screws in the body and then reinstalled by aid of a manufacturer or a trader concerned. When the installed door-lock apparatus is detached, a through-hole formed in the door remains as it is. Thus, there is a problem in that an auxiliary locking apparatus that was installed prior to the installed door-lock apparatus should be mounted again and unhidden through-holes should be plugged.

• An adhesive means such as a double-sided adhesive tape may be provided on a surface of the door-lock frame 50, which is to be brought into the upper surface of the door 500, i.e., an inner surface of the connection plate 59, and the door-lock frame 50 may be then fixed to the upper surface of the door 500 by means of the double-sided adhesive tape. Thereafter, the door-lock frame 50 is coupled to the bracket 62 of the door-lock body 60.
• the plurality of holes 55 formed in the coupling wings 50a and 50b of the door-lock frame 50 are fixedly coupled to the plurality of holes 62b formed in the bracket 62 by means of screws.
• the spacing distance between the door-lock body 60 and the door-lock frame 50 can be adjusted according to the thickness of a wall 410 above the door 500 as shown in Figs. 5 and 12.
• the coupling level of the door-lock body 60 is adjusted using the plurality of holes 62b vertically formed in the bracket 62.
• the controller 43 determines whether a serial number, which has been stored in the memory 16 of the remote control 10 and then transmitted together with the operation signal, is coincident with a previously stored serial number. That is, since the door-lock apparatus 300 of this embodiment is installed at the upper portion of the door 500, it can be locked or unlocked by control of the remote control 10 when a person moves from indoor to outdoor or from outdoor to indoor.
• the controller 43 determines a locking or unlocking state of the door 500 by means of a position sensing means (not shown) that senses a positional state of the locking bar 6 Id. If it is in a locked state, the controller 43 outputs an opening operation signal to the locking/unlocking operation unit 47. On the contrary, if it is in an unlocked state, the controller 43 outputs a closing operation signal.
• the locking/unlocking operation unit 47 operates the locking bar 61d so that the locking bar can protrude or retract. Since various examples thereof are well known in the art, a detailed description will be omitted. That is, the locked state means a state where the locking bar 61 d protrudes.
• the locking bar 61d is caught by the wall 210 above the door 500 as shown in Fig. 6 so that the door 500 is not opened. Further, if a signal of forced detachment of the door-lock apparatus 300 is input from the switch sensor 24, the controller 43 outputs an error signal to the LEDs 45 and the speaker 46 of the locking/unlocking unit 40 and the LEDs 23 and the speaker 22 of the opening/closing signal input means 20, thereby indicating the forced detachment outward. That is, as shown in Fig. 12, the switch sensor 24 that is a push/pull switch sensor is maintained in a pushed state.
• the switch sensor 24 becomes a pulled state.
• the controller 43 detects this state, determines it as a forced detachment state, and then outputs an error signal.
• the switch sensor 24 can be implemented by a switch sensor that maintains a pushed state while being in contact with the door 500 and becomes in a pulled state if the contact is released. However, it is not limited but may be implemented in various manners.
• the door-lock apparatus of the present invention can be completely installed by being put on an upper surface of a door without forming an additional through-hole used for the installation of the door-lock apparatus on the door.
• the door-lock apparatus can be conveniently installed and easily removed.
• the door-lock apparatus is installed at a position corresponding to a conventional locking bar, a fixing portion into which the locking bar is inserted is not required, there is an advantage in that the number of parts is reduced.
