FIG. 8 shows a plurality of LEDs 10 that are located outside both the guide rails 1 and are spaced apart in the height direction over the entire height of the opening, but the emitted light of the LEDs 10 crosses the opening width. The LED 10 may be provided only on either the left or right guide rail 1 as long as it has such a light quantity as possible. Further, the LEDs do not necessarily have to be arranged over the entire height of the opening, and the LEDs may be arranged only in a part of the height direction including the lower half portion in the height direction. For example, although depending on the height of the opening, only five LEDs from the bottom among all the seven LEDs 10 in FIG. 8 may be arranged.

The inner vertical member 18 is a long member extending in the height direction, and a so-called multi-axis area sensor 19 is disposed in the groove portion. For example, the multi-axis area sensor 19 emits horizontal parallel rays at intervals of 5 cm in the height direction, and detects obstacles in a wider area.

[D] Flow of operation of shutter device when entering garage FIG. 11 shows a flow of operation of the shutter device when entering the garage. FIG. 11 illustrates the case where the shutter curtain 2 stops in the fully opened state of the opening, but the same flow is performed when the rising shutter curtain 2 stops halfway. In FIG. 1, the shutter curtain 2 is in a fully closed posture, both ends in the width direction of the shutter curtain 2 are positioned in the grooves of the left and right guide rails 1, and the lower end of the shutter curtain 2 is grounded to the floor surface. The opening is in a fully closed state. In a normal opening fully closed state, the LED 10 is turned off. In this state, when an open signal is transmitted from the remote operation device in the vehicle, the opening / closing device 5 is driven via the shutter control panel, and the winding shaft 4 is rotated in the first direction to wind the shutter curtain 2. Ascending while being wound around the take-up shaft 4, the opening is opened and the shutter curtain 2 is in a fully open posture.

When an open signal is transmitted from the operation unit, a control signal is output to the switch 5 via the shutter control panel, an electrical contact is closed and an electrical signal is output to the illumination means, and the LED 10 is energized and lit. To do. While the switch 5 is driven based on the open signal, power is continuously supplied to the LED 10, and the LED 10 is continuously lit while the shutter curtain 2 is raised. In the present embodiment, any LED 10 may be energized in conjunction with the input of the open signal, and specific means can be appropriately designed by those skilled in the art, and those using a transfer contact are used. It is not limited.

A timer is activated for a predetermined time from the time when the shutter curtain 2 that is being raised stops, and the LED 10 is controlled to continue to be lit for a predetermined time. The means for detecting the stop of the shutter curtain 2 can be determined, for example, by detecting whether or not the switch 5 is energized or detecting whether or not the rotating shaft of the switch 5 is rotating. In one embodiment, the predetermined time is 5 minutes, and the LED 10 is turned on only for 5 minutes after the rising shutter curtain 2 stops, and the LED 10 is turned off after 5 minutes. Therefore, after the shutter curtain 2 starts to rise due to the input of the open signal, the shutter curtain 2 stops at the upper limit position and the LED lights up for a predetermined time (5 minutes) after the opening is fully opened, and the garage is put in between To do. In addition, you may control so that LED10 becomes dark gradually when it turns off.

When a stop signal is input while the shutter curtain 2 is moving up, the LED 10 is continuously lit for a predetermined time (5 minutes) by a timer while the shutter curtain 2 is stopped before it is fully opened. Yes. When the shutter curtain 2 is stopped in the middle of rising, when an open signal is input again and re-raising starts, the timer count is reset when the timer is operating, and the position where the shutter curtain 2 stopped again (typically, The timer starts counting from 0 at the upper limit position).

In this embodiment, the LED 10 is turned on when the shutter curtain 2 operates regardless of the opening and closing operations of the shutter curtain 2, and the timer counts when the shutter curtain 2 stops regardless of the opening and closing operations of the shutter curtain 2. At the beginning, the counter is reset when the shutter curtain 2 starts to move again. Thus, for example, when the garage entry is completed and the close button is pressed from inside the vehicle during the timer count for 5 minutes, the timer is reset and the shutter curtain 2 is lowered to turn on the LED. It can continue and get off while the LED is lit, and when fully closed, the timer starts counting with the transfer contact signal, and the LED 10 turns off after 5 minutes. In the present embodiment, when the shutter curtain 2 is closed in the dark, the LED 10 is illuminated, so safety is improved.

In the present specification, two modes are disclosed as the illumination unit, but the illumination unit 1 and the illumination unit 2 may be combined. For example, the LED 10 may be arranged in a gate shape in the upper part of the opening and the left and right in the width direction, or the LED 10 may be arranged in an L shape in one of the upper part of the opening and the width direction. In addition, although this invention was demonstrated based on embodiment which concerns on a winding-type electric shutter, you may employ | adopt this invention for what is called an overhead door.

The insertion portion 21 includes opposed rising walls 210 and 210 extending in the opening width direction (length direction of the light diffusion cover 20), and the upper end side is integrally connected by a curved portion 211 having an upward bulging shape. Yes. A protrusion 212 extending horizontally in the opening width direction (the length direction of the translucent resin cover 20) is formed on the upper portion of each rising wall 210, 210. In the mounted state, the rising wall 210 is in contact with the folded portion 923 of the outer vertical side 920 and the inner vertical side 921, and the lower protrusion 212 is positioned immediately above the upper edge of the folded portion 923. Since the protrusion 212 of the light diffusion cover 20 is located at the upper edge of the folded portion 923, the light diffusion cover 20 is prevented from falling. Since the light diffusion cover 20 can be elastically deformed, even if the insertion portion 21 has the protrusion 212, the insertion of the insertion portion 21 of the light diffusion cover 20 from the opening at the lower end of the groove portion 92 is not hindered. Further, since the light diffusing cover 20 can be elastically deformed, the light diffusing cover 20 can be satisfactorily removed when replacing the LED.

The light diffusing cover 20 has the effect of (a) diffusing light emitted from the LED 10 with high linearity passing through the light diffusing cover 20 and illuminating with a uniform intensity in the opening width direction. ing. If the light diffusion cover is not provided, the emitted light of the plurality of LEDs arranged at intervals in the opening width direction goes straight to the lower side of each LED to make a bright part, but between adjacent LEDs A dark part is formed below the light and dark and light parts are alternately formed in the opening width direction. By providing the light diffusing cover 20, the difference in brightness in the opening width direction in the illumination from the plurality of LEDs 10 is reduced, and the full width area of the opening is illuminated with a more uniform intensity to improve the appearance. By providing the light diffusion cover 20, the emitted light from one LED 10 passes through the light diffusion cover 20 and is emitted as a wider range of light, and the installation interval of the LEDs 10 can be increased according to the degree of light diffusion. As a result, the full width region of the opening can be illuminated with a smaller number of LEDs 10. The light diffusion cover 20 also has an action of softening light emitted from the LED 10 and illuminating with soft light.

The light diffusing cover 20 further has the effects of (a) protecting the LED 10 (waterproof, dustproof, etc.) and (c) making the wiring inconspicuous even when viewed from below.
