Description

The present invention relates to an automatic door that can be opened hands-free.

2. Description of the Related Art An automatic door is known in which an authentication device and an authentication key are prepared and an authentication device provided on the automatic door side authenticates an authentication key possessed by a passerby and opens the automatic door. In particular, the authentication device transmits a first wireless authentication signal as an authentication radio wave, and the authentication device receives and authenticates the second wireless authentication signal transmitted from the authentication key that received the first wireless authentication signal. The automatic door can be opened hands-free.

Such an automatic door is installed, for example, at the entrance of an apartment house such as an apartment. Conventional authentication devices are often provided in so-called collective entrances provided on the side wall of the entrance (building opening). As for the position where the authentication device is provided, there is also proposed a device in which the antenna of the authentication device is installed on the ceiling above the opening or invisible (Patent Documents 1 and 2).

However, in the former case, depending on the space of the entrance, there may be a predetermined distance from the authentication device (radio wave transmitter) to the passage (in the case of a double door automatic door, near the center of the building opening). In the latter, depending on the opening height, there may be a predetermined distance from the authentication device (radio wave transmitter) to the authentication key on the passage (for example, the authentication key is at the bottom of the handbag).

Here, limiting the transmission range of the authentication radio wave transmitted from the authentication device is advantageous in eliminating malfunction of the automatic door (opening of the door when it is unnecessary, etc.). If the transmission range of the authentication radio wave is set wide, for example, an authentication key of a person or the like who goes out from the entrance is detected and the automatic door is opened, which may lead to intrusion of a third party.

Therefore, when the predetermined distance is beyond the transmission range of the authentication radio wave, in the former case, it deviates from the linear traveling path and approaches the collective entrance machine, and in the latter case, it is a handbag. Lifting the card requires authentication and reduces the hands-free purpose.

In particular, when the first wireless authentication signal as the authentication radio wave transmitted from the authentication apparatus is an LF signal (LF: low frequency), the reach of the authentication radio wave is shorter than the RF signal (RF: radio frequency). (The distance attenuation of the RF signal attenuates in inverse proportion to the square of the distance, whereas the distance attenuation of the LF signal is inversely proportional to the cube of the distance). Although it may vary depending on the signal strength, the authentication range of the authentication radio wave of the LF signal is, for example, within 2 m. Therefore, it is necessary to realize an automatic door that can be effectively authenticated and opened hands-free even if the authentication radio wave is an LF signal.

The predetermined part in the height direction of one side 3 (the part in which the authentication unit 6 is incorporated) is a part of the outdoor part of the outdoor finding surface 30 and the internal prospecting surface 32 over a predetermined height, A part of the outdoor side surface 330 of the outer expected surface 33 is cut away. An authentication unit 6 is attached inside the notched part. The authentication unit 6 is the same as the authentication unit 6 in the first embodiment, and the above description can be used for a specific configuration.

In the present embodiment, a mounting plate 12 having a U-shaped cross-sectional view from the front portion 120 and the left and right side portions 121 and 122 is provided on the outdoor side of the reinforcing member on the indoor side of the vertical 3. It is supported by a screw 16 extending from the finding surface 31. The authentication unit 6 is attached by fixing the base 60 to the front portion 120 of the attachment plate 12 with screws 13.

The authentication unit 6 built in the notch formed in the outdoor side finding surface 30 of the vertical 3, a part of the outdoor side portion of the inside prospecting surface 32, and a part of the outdoor side surface 330 of the outside prospecting surface 33. A cover body 9 'is attached so as to cover the surface. The cover body 9 ′ is a cross-sectional view from the finding surface 90 and the side surfaces 91, 92 corresponding to the cutout portions of the outdoor finding surface 30, the inside looking surface 32, and the outside looking surface 33 of the vertical 3. A first piece 910 having a letter-shaped portion and extending from the end portion of the side surface 91 so as to face the finding surface 90; and a second piece extending from the tip end of the first piece 910 toward the indoor side in the expected direction. 911, a first piece 920 that extends from the end of the side surface 92 to face the finding surface 90, and a second piece 921 that extends from the tip of the first piece 920 toward the indoor side in the expected direction. . The cover body 9 ′ is mounted by fixing the left and right second pieces 911 and 921 to the left and right side surfaces 121 and 122 of the mounting plate 12 with screws 17, respectively.

With the cover body 9 ′ fixed to the vertical 3, the finding surface 90 and the side surfaces 91, 92 are the outdoor finding surface 30, the inner looking surface 32, and the outdoor looking surface 330 of the outer looking surface 33 of the standing 3. The outer surface of the vertical 3 is formed together with the outdoor outer surface 30 of the vertical 3, the outer half of the inner surface 32, and the outdoor surface 330 of the outer surface 33.

The cover body 9 ′ is made of a resin that can transmit the authentication radio wave (in this embodiment, is formed from an acrylic resin), and the whole of the finding surface 90 and the side surfaces 91 and 92 is a radio wave transmitting portion. . The finding surface 90 of the cover body 9 ′ faces the transmission antenna 61 of the authentication unit 6 (FIGS. 8 and 10), and the side surface 91 faces the side portion of the transmission antenna 61 of the authentication unit 6. (FIGS. 9 and 10). Although the side surface 92 does not need to be a radio wave transmitting portion, the design is improved by making the cover body 9 'symmetrical.

FIG. 12 and FIG. 13 show the influence of the position of the radio wave transmitting portion formed in the vertical 3 on the radiation range of the radio wave from the transmitting antenna 61 (radio wave transmitting portion) of the authentication unit 6 built in the vertical 3. This will be explained based on. FIG. 12 is a schematic diagram of the radiation range of a radio wave when the radio wave transmission part is formed only on the vertical outdoor side finding surface 30 (the scope of the present invention includes such an aspect). . A part of the radio wave radiated from the transmitting antenna 61 (radio wave transmitter) provided inside the outdoor-side finding surface 30 of the vertical 3 (particularly, the part toward the opening width direction) It will be shielded by the presence of the prospective surfaces 32 and 33 (made of metal) on both sides. Therefore, there is a possibility that a non-reachable area for the authentication radio wave may be generated outside the entrance of the automatic door.

FIG. 13 shows the radiation of radio waves when the radio wave transmission part is continuously formed on the outdoor side finding surface 30 of the vertical 3 and the prospecting surfaces 32 and 33 on both sides (for example, the second embodiment of the present invention). FIG. 12 is a schematic diagram of the range (in the case of the first embodiment of the present invention, the radiation range not directed to the left vertical frame 4 on the side opposite to the opening is like the radiation range shown in FIG. 12). . The radio waves radiated from the transmitting antenna 61 (radio wave transmitter) provided inside the outdoor side finding surface 30 of the vertical 3 are transmitted from the outdoor side finding surface 30 of the vertical 3 to both sides of the vertical 3. Of the radio wave radiated from the transmission antenna 61 (radio wave transmission unit) toward the opening width direction. Is radiated through the radio wave transmitting portion formed on the prospective surface 32. Therefore, it is possible to prevent as much as possible the generation of the non-reachable area of the authentication radio wave outside the entrance of the automatic door. For comparison, it should be noted that in FIGS. 12 and 13, the radiation range is drawn a little extreme.

Further, the front portion 930 of the radio wave transmitting portion 93 and the upper ends 9300 and 9310 of the side surface portion 931 are located above the upper end of the transmitting antenna 61 (radio wave transmitting portion), and the lower ends 9301 of the front surface portion 930 and the side surface portion 931. , 9311 are located below the lower end of the transmission antenna 61 (radio wave transmission unit), so that the radio wave radiated from the transmission antenna 61 passes through the radio wave transmission unit 93 and is not shown. Radiation is spread in the vertical direction, reducing the occurrence of non-reachable areas for authentication radio waves in the height direction. For example, if the lower end of the radio wave transmitting portion is positioned above the lower end of the radio wave transmitting portion, the downward spreading of the radio wave radiated from the transmitting antenna 61 is limited by the metal part immediately below the lower end of the radio wave transmitting portion. Therefore, there is a possibility that a non-reachable area for the authentication radio wave may be generated on the lower side in the height direction.
