  The best mode for carrying out the automatic door device of the present invention will be described below with reference to the drawings.

[First Embodiment]
FIG. 1 is a schematic front view of an automatic door device according to a first embodiment of the present invention, FIG. 2 is a sectional view of a door main body along the line AA in FIG. 1, and FIG. It is sectional drawing of the door main body along a line.

  As shown in FIG. 1, the automatic door device 1 according to the first embodiment is slid laterally along a wall W by a drive unit 2 installed at an upper part of a building entrance and exit. And a door body 3 that is opened and closed.

  Above the door body 3, there is provided a detection sensor 4 including an optical sensor for detecting an object such as a person or an object within a set area. When an object is detected by the detection sensor 4, the door main body 3 is moved along the wall W by the drive unit 2, and the doorway is opened. A frame body 5 is provided on both sides of the door body 3.

  As shown in FIGS. 2 and 3, the door body 3 includes light guide plates 31 and 32, a pair of door plates 33 and 34, light sources 35 and 36, and substrates 37 and 38.

  The light guide plates 31 and 32 are constituted by rectangular plates made of a transparent material. As the material of the light guide plates 31 and 32, synthetic resin such as acrylic resin, polycarbonate resin, silicone resin, cyclopolyolefin resin, or the like, or glass is used. Among them, acrylic resin is used in terms of transparency and ease of processing. Is preferred. The thickness of the light guide plates 31 and 32 can be set to 1 mm to 3 mm, for example.

  Display portions 40a and 40b each including a plurality of dot-shaped recesses 39 are formed on the rear surfaces 31c and 32c of the light guide plates 31 and 32.

  FIG. 4 is a partially enlarged view of the periphery of the recess in FIGS. The concave portion 39 has a reflection surface 39a that reflects the light emitted from the light sources 35 and 36 and incident from the end surfaces 31a and 32a of the light guide plates 31 and 32 toward the surfaces 31b and 32b of the light guide plates 31 and 32. The recess 39 is shaped such that light from the light sources 35 and 36 strikes the reflecting surface 39a. For example, the recess 39 has a cross section that is a substantially rectangular shape in plan view and has a triangular shape with the reflective surface 39a as a hypotenuse (see FIG. 4).

  The planar view shape of the recess 39 is not limited to a rectangle, but may be a polygon such as a triangle or a pentagon, a circle, an ellipse, or the like.

  If the inclination angle (angle α shown in FIG. 4) of the reflection surface 39a with respect to the rear surfaces 31c and 32c of the light guide plates 31 and 32 is too small, the inclination angle of the emitted light also increases, and the door body 3 is front-facing (FIGS. 2 and 3). Visibility of the recess 39 when viewed from the left side of FIG. If the inclination angle α is too large, the incident angle of light exceeds the critical angle and the proportion of light transmitted through the reflecting surface 39a increases, so that the light reflection efficiency decreases and the light use efficiency decreases.

  For this reason, the inclination angle α of the reflecting surface 39a is preferably 40 degrees or more and 60 degrees or less, and more preferably 50 degrees or more and 55 degrees or less. By making the inclination angle α in the above range, the light reflection efficiency is increased, and the reflected light is emitted at an angle close to the surfaces 31b and 32b of the light guide plates 31 and 32, thereby improving the visibility of the recess 39. be able to.

  In the illustrated example, the reflecting surface 39a is planar, but at least a part of the reflecting surface may be planar, and a part may be configured by a curved surface. Moreover, you may make the shape of a reflective surface different in each reflective surface. If the reflecting surface is a curved surface, the emission angle of the reflected light may be in a wide range. In this case, the concave portion 39 can be viewed from a wide range.

  In addition, in order to increase the light reflection efficiency on the reflection surface 39a, it is desirable to form the surface of the reflection surface 39a smoothly.

  When the planar view areas of all the recesses 39 are the same, the brightness of the reflected light in the recesses 39 far from the light sources 35 and 36 tends to be lower than the reflected light in the recesses 39 close to the light sources 35 and 36. For this reason, it is preferable to make the brightness of the reflected light of the recess 39 uniform by increasing the planar view area of the recess 39 in accordance with the distance from the light sources 35 and 36.

  The recess 39 is preferably arranged so as to form a combination of one or more of characters, symbols, figures, and patterns. In addition, the display unit 40a formed on the light guide plate 31 and the display unit 40b formed on the light guide plate 32 may display any one or more combinations of different characters, symbols, figures, and patterns. A plurality of recesses 39 are preferably arranged.

  FIG. 5 is a view of the display unit 40a including a plurality of recesses 39 formed on the light guide plate 31 from the surface 31b side. FIG. 6 illustrates the display unit 40b including a plurality of recesses 39 formed on the light guide plate 32 on the surface 32b. It is the figure seen from the side.

  5 and 6, the display unit 40a displays an arrow pattern indicating the direction in which the door body 3 closes, and the display unit 40b has the recesses 39 arranged so as to display an arrow pattern indicating the direction in which the door body 3 opens. Yes. As shown in FIG. 1, the display units 40 a and 40 b are arranged so that the display unit 40 is configured to show an arrow pattern in both directions that combines the display units 40 a and 40 b when viewed from the front of the door body 3. ing.

  The method for forming the recesses 39 in the light guide plates 31 and 32 is not particularly limited. As an example, a molding die corresponding to the recesses 39 in a state where a resin plate made of acrylic resin is heated and softened. Is inserted into the resin plate. After cooling the resin plate in this state, the recess 39 can be formed in the light guide plates 31 and 32 by removing the molding die from the resin plate. Note that the recess 39 can be formed by cutting, press molding, injection molding, or the like.

  The door plates 33 and 34 are constituted by plates made of a transparent material having substantially the same shape as the light guide plates 31 and 32. As a material of the door plates 33 and 34, for example, glass is used.

  In the present invention, the term “transparent” means that the reflected light from the concave portion 39 is light transmissive. This definition is commonly used in the present invention.

  The light sources 35 and 36 are arranged so that light can be incident on end surfaces 31a and 32a on one side of the light guide plates 31 and 32, respectively. The light sources 35 and 36 are formed to extend along the end surfaces 31a and 32a of the light guide plates 31 and 32, and include, for example, a plurality of LEDs arranged in a direction along the end surfaces 31a and 32a.

  The light sources 35 and 36 are preferably configured to emit different color lights. For example, an LED that emits red light is used as the light source 35, and an LED that emits blue light is used as the light source 36.

  The substrates 37 and 38 are electrical substrates that are electrically connected to the light sources 35 and 36, respectively, and supply a drive current to the light sources 35 and 36.

  The light guide plates 31 and 32 are arranged side by side with a predetermined interval by spacers 41 and 42, and the door plate 33 is arranged on the surface 31 b side of the light guide plate 31 with a spacer 43 and a substrate 37 with a predetermined interval. The door plate 34 is arranged on the back surface 32c side of the light guide plate 32 with a spacer 44 and a substrate 38 with a predetermined interval. As described above, the light guide plates 31 and 32 are arranged in parallel between the pair of door plates 33 and 34, and a predetermined interval is maintained between the door plates 33 and 34 by the spacers 45 and 46.

  The light guide plates 31 and 32 and the door plates 33 and 34 are fixed by a steel frame 47 having a U-shaped cross section surrounding the periphery thereof. The light sources 35 and 36, the substrates 37 and 38, and the spacers 41 to 46 are arranged at positions covered by the frame 47 and are not visible from the front of the door body 3.

  FIG. 7 is a functional block diagram of the automatic door device 1. The control unit 6, the door control unit 7, and the drive unit 8 illustrated in FIG. 7 are provided in the drive unit 2.

  The control unit 6 is connected to a detection sensor 4 installed above the door body 3, receives a detection signal from the detection sensor 4, and transmits a control signal to the door control unit 7 based on the detection signal. The control unit 6 includes a light source control unit that is connected to the light sources 35 and 36 and controls driving of the light sources 35 and 36 based on the sensing signal.

  The door control unit 7 drives the drive unit 8 based on a control signal from the control unit 6. The drive unit 8 includes a motor or the like and moves the door body 3.

  Next, the operation of the automatic door device 1 will be described.

  When an object such as a passerby approaches the door body 3 and enters an area that can be sensed by the sensing sensor 4, the sensing sensor 4 senses the object and transmits a sensing signal to the control unit 6.

  When the control unit 6 receives the detection signal from the detection sensor 4, the control unit 6 transmits a control signal to the door control unit 7, and the door control unit 7 drives the drive unit 8 to move the door body 3 in the opening direction. At the same time, the control unit 6 causes the light source 36 to emit light while the door body 3 is moving.

  Light from the light source 36 enters from the end surface 32 a of the light guide plate 32 and travels through the light guide plate 32. As shown in FIG. 4, most of the light traveling through the light guide plate 32 and reaching the reflection surface 39 a of the recess 39 is reflected by the reflection surface 39 a and is emitted from the surface 32 b of the light guide plate 32.

  When viewed from the front side of the door body 3 (on the surface 32b side of the light guide plate 32), the concave portions 39 are observed as dot-like bright spots. Thereby, the arrow pattern of the display part 40b which consists of several recessed part 39 is visually recognized.

  When the door main body 3 moves to a position where the door main body 3 is fully opened, the control unit 6 transmits a control signal to the door control unit 7 to stop the door main body 3 by the driving unit 8 and simultaneously turns off the light source 36.

  After that, after receiving a detection signal from the detection sensor 4, when a predetermined time has elapsed as a time during which a passerby can pass through the door body 3, the control unit 6 sends a control signal to the door control unit 7. And the door control unit 7 drives the drive unit 8 to move the door body 3 in the closing direction. At the same time, the control unit 6 causes the light source 35 to emit light while the door body 3 is moving.

  Of the light from the light source 35 incident from the end surface 31 a of the light guide plate 31, most of the light that reaches the reflective surface 39 a of the concave portion 39 constituting the display unit 40 a is reflected by the reflective surface 39 a and reflected by the light guide plate 31. The light is emitted from the surface 31b. Accordingly, when viewed from the front side of the door body 3 (the surface 31b side of the light guide plate 31), the arrow pattern of the display unit 40a including the plurality of recesses 39 is visually recognized.

  Thereafter, when the door body 3 moves to a closed position, the control unit 6 transmits a control signal to the door control unit 7 to stop the door body 3 by the driving unit 8 and simultaneously turns off the light source 35.

  As described above, according to the first embodiment, while moving the door main body 3 in the direction of opening the doorway, the light source 36 emits light and the arrow-shaped display portion 40b indicating the direction of opening the door main body 3 emits light. While the door body 3 is moved in the direction of closing and closing the doorway, the light source 35 emits light and the arrow-shaped display portion 40a indicating the direction of closing of the door body 3 is displayed. This can reduce the risk of safety and ensure safety.

  If the light sources 35 and 36 are light sources that emit light of different colors, different colors are displayed when the door body 3 moves in the direction of opening / closing the doorway and in the closing direction. It is possible to inform the passers-by in a clear manner.

  Most of the light reaching the reflecting surface 39a of the concave portion 39 of the light guide plates 31 and 32 is reflected by the reflecting surface 39a and travels in a substantially constant direction (in the illustrated example, a direction perpendicular to the surfaces 31b and 32b). The luminance per unit area of light becomes sufficiently large. For this reason, since the area of the recessed part 39 can be restrained small, the transparency of the door main body 3 and the designability are not impaired. Therefore, when the door main body 3 is not moving, it appears transparent, and the display portions 40a and 40b are displayed so as to float only when the door main body 3 is opened and closed.

  Note that the timing for causing the light sources 35 and 36 to emit light may be set a certain time before the opening and closing movement of the door body 3 is started. Thereby, a passerby can be notified in advance that the door body 3 starts to move, and safety can be further improved.

  Further, for the purpose of decorating the door body 3, a light guide plate other than the light guide plates 31 and 32 and a light source corresponding thereto are provided, and the light guide plate is combined with any one or more of letters, symbols, figures and patterns. May be formed so as to display the light emission display regardless of the movement of the door body 3 or in association with the movement of the door body 3.

  Further, the detection sensor for detecting the approach of the object is not limited to the optical sensor, and a contact sensor or the like may be used.
