As shown in Figure 3, the lower drive automatic according to the present invention comprises an operation door 100, a main frame 200 in which the automatic door 100 is installed, a lower frame 300 which is installed at a lower side of the main frame 200, a driving unit 400 for opening and closing the automatic door, a lower roller unit 500 which is installed at one lower side of the automatic door 100, a lower rail frame 600, an upper roller unit 121 which is installed at an
upper side of the automatic door 100, and an upper rail frame 700.
The automatic door 100 is constructed as a glass 130 is installed between a lower frame member 110 and an upper frame member 120.
As shown in Figure 4, a lower roller frame 510 is installed at one side of the lower frame member 110 of the automatic door 100, and a driving roller 520 is installed at one side of the lower roller frame 510 in a vertical direction for guiding a sliding open and close operation of the automatic door 100. A lower escape prevention roller 530 is installed on a lower surface of the lower roller frame 510 in a horizontal direction for preventing the driving roller 520 from being escaped. As shown in Figure 4, the lower frame 300 is installed at a lower side of the main frame 200, and a driving motor 410 is installed at one inner side of the lower frame 300 for rotating a driving pulley 420 of an upper surface in reverse or normal directions, and a driven motor 440 is installed at the other side. A controller 470 is installed in the interior of the lower frame 300 for controlling the driving motor 410. At this time, the driving pulley 420 and the driven pulley 440 are engaged by means of a driving belt 430, and a belt clip 450 is engaged at the driving belt 430. The belt clip 450 is connected with the lower roller frame 510 via a connection member 460.
As shown in Figure 4, the lower rail frame 600 comprises a driving rail 610 for guiding the movement of the driving roller 520, and a lower escape prevention rail 620 for guiding the movement of the lower escape prevention roller 530. Here, the driving rail 610 and the lower escape prevention rail 620 are perpendicular to each other and are engaged.
As shown in Figure 5, the upper roller unit 121 comprises a hanger roller 121a and an upper escape prevention roller 121b which are installed on the upper frame member 120 of the automatic door 100.
Here, the hanger roller 121a is installed at one side of the upper frame member 120 in a vertical direction, and the upper escape prevention roller 121b is installed on an upper surface of the upper frame member 120 in a horizontal direction. As shown in Figures 3 and 5, a pair of upper guide rollers 730 and 740 are installed at the left and right sides of a lower surface of the upper rail frame 700, so that the automatic door 100 is stable opened and closed on a slide basis as they rotate in contact with a glass 130 of the automatic door 100.
Figure 6 is a view illustrating a lower guide roller unit 140 which is installed at the other side of a lower side of the automatic door 100 and which consists of a spring damper 141 for absorbing vibrations and a lower guide roller 142. Namely, the spring damper 141 is installed in the interior of the lower frame member 110, and the lower guide roller 142 is installed at the spring damper 141. The lower guide roller unit 140 moves along the lower guide rail 630 which is extended from the lower frame 600 for thereby absorbing vibrations which occur as the automatic door 100 is opened and closed on a sliding basis, and supporting a stable opening and closing operation.
Figure 7 is a view illustrating a display unit 800 installed on the automatic door 100. It consists of a display apparatus 810, a card key 820, and a sensor 830. As shown in Figure 8, a power cable 152, which consists of a communication cable for controlling the display unit 800 and a power supply cable for supplying electric power to the display unit 800, is installed along a power cable guide 151 installed between a profile 150 formed at an outer side of the automatic door and the glass 130. An elastic member 160 is installed on the profile 150 for absorbing external impact.
In the lower drive automatic door of the present invention, the sensor 830
installed on the automatic door 100 detects that a person approaches, and the detected signal is transmitted to the controller 470. The controller 470 rotates the driving motor 410, and the driving belt 430 engaged at the driving pulley 420 rotates in a counterclockwise direction with the help of the driving motor 410. The belt clip 450 installed at the driving belt 430 moves rightward for thereby pulling rightward the lower roller unit 500 connected via the connection member 460.
The driving roller 520 of the lower roller unit 500 rotates along the driving rail 610 of the lower rail frame 510, and the automatic door 100 is opened. Here, the lower escape prevention roller 530 of the lower roller unit 500 rotates along the lower escape prevention rail 620 for thereby preventing an escape of the driving roller 520.
The hanger roller 121a of the upper roller unit 121 rotates along the hanger rail 710 at the time when the driving roller 520 and the lower escape prevention roller 530 operate, and the upper escape prevention roller 121b rotates along the lower escape prevention rail 620 for thereby preventing an escape of the hanger roller 121a.
As the automatic door 100 is opened, and a person passes through, when a standby time set in the controller 470 is passed, the controller 470 allows the driving motor 410 to rotate in the direction opposite to the direction when the automatic door 100 is opened, and the driving belt 430 rotates in a clockwise direction, so that the automatic door 100 is closed.
The display apparatus 810, the card key 820 and the sensor 830 of the display unit 800 installed on the automatic door 100 are made of known elements. So, the functions and construction of the same may be omitted. The display apparatus 810 of the display unit 800 is designed to display a lot of information and advertisements. A touch screen type display apparatus 810 is installed at a front
side and a backside of the automatic door 100, respectively, so that it may be used as a password input member except as an information display and advertisement display member.
