Description

Left and right hand type digital door lock

The present invention relates to a digital door lock, wherein when the body of the door lock is rotated by 180°, a light source corresponding to the first and second display units is selectively selected by a rotating member in order to properly indicate either the first display unit or the second display unit. By blocking, it relates to a left and right type switchable digital door lock that can be easily and conveniently installed and used in common for the left type door and the excellent type door.

In general, Digital Door Lock is a high-tech locking device that uses passwords, semiconductor chips, smart cards, fingerprints, etc. instead of existing keys. Most digital door locks open and close the door by an electronic reaction using an electronic key, password, card or fingerprint recognition. The access control system using such a digital door lock is not a means for simply blocking the door, but restricts or opens the access when necessary, thereby creating an environment that can be adjusted in the form desired by the user.

On the other hand, due to the compressive ability generated on the surface and the tensile ability generated inside, it is not easily damaged than ordinary glass, and when it is broken, the particles are broken into non-sharp pieces. (Tempered Glass) is widely used. Since the tempered glass door has a strong material and is very difficult to additionally process in the future, the digital door lock used for the tempered glass door is equipped with an inner body installed on the inside of the door, and an exterior installed on the outside of the door with a key input unit. It includes a body and is configured such that the inner body and the outer body are fixed by a bracket coupled to the door.

However, the left-handed door that holds the tempered glass door in the left-hand position and the excellent-type door that is held with the right hand side has a different direction in which the dead bolt protrudes from the left and right sides. However, since the outer body is integrally fixed by the bracket and flipped together, the key input unit is flipped together, so the position of the number of the key input unit and the number itself are flipped, making it impossible to use.

In the following patent document 1 for solving the above problems, the out-body coupling structure of the digital door lock is published, and any one of the pair of coupling holes of the outbody is mounted on the rotating plate mounted on the front plate of the bracket. As the outer body rotates the coupling part of the rotating plate so that it is aligned with the coupling hole, the outer body is separated from the rotating plate, and then rotated to connect the other coupling holes of the outbody. In addition to falling, there is a problem that the working time is increased due to the complicated work process due to the removal and assembly of the outbody when switching to the left-handed excellent type.

On the other hand, the touch unit is separated into the first touch unit 111 and the second touch unit 112 so that only the button recognition of the first and second display units 121 and 122 corresponding thereto is possible for each touch area. Is composed.

In the case of a left-handed installation, only the first display unit 121 is displayed, and the touch units located in the first row and 1 column corresponding to the first display unit 121 are recognized as number 1, and the touch units located in the seventh row and 3 columns are recognized as the symbol #. , When the door lock is rotated 180° and converted to an excellent type, only the second display unit 122 is displayed, and the touch unit located in the 8th row and 3rd column is converted to the 1st row and 1st column when the left-handed type is recognized as a number 1 Since the located touch part is converted into 7 rows and 3 columns, it is recognized as the symbol #.

When the sensor detects that any one of the first and second openings 131 and 132 is blocked from the light source due to the rotation of the rotating member 140 described below, the touch panel 110 is placed in the unblocked opening. Only the corresponding touch unit is configured to be touch recognized.

That is, when a sensor (photosensitive sensor, magnetic sensor, position sensor, etc.) (not shown) detects that the first opening 131 is blocked from the light source by the rotating member 140, the first touch unit 111 is operated. By allowing only the second touch unit 112 to perform touch recognition without doing so, although in this case only the second display unit 122 is displayed on the touch panel 110 and the first display unit 121 is not expressed, Even when the user incorrectly presses the first display unit 121 other than the second display unit 122, the touch panel 110 does not recognize the number or symbol of the pressed touch unit.

The display panel 120 will be described. The display panel 120 is coupled to the rear surface of the touch panel 110 and is attached together on the front surface of the external frame 130, and a display unit indicating a set of input buttons (numbers/symbols, etc.) 2 The display unit 122 is divided into even and odd rows, Is formed.

(Based on the left-hand type, for example) an odd-numbered first display unit 121 corresponding to the first touch unit 111 and a first display unit 121 corresponding to the first touch unit 111, but inverted to the first display unit 121 The even rows of first display portions 121 to be displayed are formed.

The buttons of the first display unit 121 and the second display unit 122 are formed in a 180° inverted shape. That is, the first display unit 121 arranged along odd rows is formed by sequentially erecting numbers and symbols from 1 to # in the direction from the upper left to the lower right from the 1st row to the 8th row and 3rd column. Conversely, the second display units 122 arranged according to the performance are formed by sequentially inverting numbers and symbols from 1 to # in the direction from the lower right to the upper left from the 8th row and 3rd column to the 1st row and 1st column.

Meanwhile, each number and symbol constituting the display unit is a structure in which at least one side of the display panel 120 is printed in various ways, and the buttons on which light by the light source unit is printed on the display panel 120 are displayed on the display panel 120. By projecting directly on the front touch panel 110 (and on the window), numbers or symbols expressed on the buttons are displayed to the user.

For example, in the prior art, a display element comprising a first/second display unit and a first/second display unit and a light source for display display of the display unit are included, but as the display element rotates around the swing axis, the first/second display unit In the case of a configuration in which the second display portion is reversely displaced so that the display portion is selectively exposed by a light source, numbers and symbols constituting the first/second display portions are formed through the display element.

Therefore, there may be no limit to the number display method of the first/second display units. In other words, when the number '0' is formed through the display element, it is in the form of'[]', and it cannot but be expressed in a separate form taking into account the connection part in the middle, so the number '0' cannot be visually expressed and spreads. A phenomenon and/or a depression phenomenon in which the buttons appear to have entered the inside are indicated. Also, the same is true for the numbers '8' or '6'.
