Is sent to the light emitting unit, converted into light and sent to the light receiving unit, and the signal is sent from the light receiving unit to the control unit of the door drive unit. Further, in the automatic door disclosed in Japanese Patent Laid-Open No. 58-218572, a light emitting diode is used as a light emitting portion for receiving a signal from a door switch to emit light, and a phototransistor is used as a light receiving portion. Moreover, a solar cell is used as the transmitter of the door switch, eliminating the need for battery replacement.

[0004]

[Problems to be solved by the device]

 In the case of the wired door switch described above, the signal transmitted from the door switch is reliably sent to the door drive control section without being affected by wind and rain, but on the other hand, the above code is used for the door. Accidents that often prevent the opening and closing of the door or lock the door itself occur.

On the other hand, in the case of the wireless type door switch, it is possible to avoid the accident as described above, but all of the wireless type switches are easily affected by wind and rain, etc. The response may be unstable. Therefore, there are many concerns about installing in a place where it is exposed to direct wind and rain.

The present invention has been made for the purpose of fully exerting the advantages of the wired door switch and eliminating the drawbacks thereof. Even if there is, it will provide an automatic door that makes it easy to operate the switch.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the main structure of the present invention is an automatic door that automatically opens and closes by 0N, OFF operation of the touch switch, wherein the touch switch is a long elastic switch, and the elastic switch is the entrance height. It is characterized in that it is attached to the fixed part over almost the entire length.

[0008]

[Action]

 Since the elastic switch is attached to the fixed part of the doorway (vertical frame, vertical frame of fixed door), the cord connecting the elastic switch and the door drive controller can be fixedly wired along the fixed part, and therefore the wire breakage. Accidents that would prevent the door from opening and closing, and the switch position remains unchanged, so the switch can be easily operated even when the door is in operation, and the battery can be replaced because commercial power is available. Is also avoided. Further, since the elastic switch is installed over substantially the entire length of the fixing portion in the height direction, the switch can be easily operated regardless of the posture or height.

The switch is a strip-shaped elastic switch, and fourthly, the strip-shaped elastic switch is attached over substantially the entire length of the vertical frame or the vertical frame in the longitudinal direction.

In FIG. 1, reference numeral 1 is a strip-shaped elastic switch, and the basic structure of the elastic switch 1 is a pair of elastic switches that are opposed to each other at a predetermined interval and are urged in a direction in which they are relatively separated from each other. The strip-shaped conductor is provided, and a pressing member is attached to at least one of the strip-shaped conductors over the entire length, and presses the same pressing member against the other strip-shaped conductor, Alternatively, the pressure is released to make the switch circuit 0N, OFF. As a typical elastic switch 1, for example, a hollow cylindrical body made of a synthetic rubber material such as silicon rubber and having a substantially elliptical cross section is provided along the entire length so as to face the inner wall surface of the elliptical hollow portion. Some of them are made of conductive rubber, and the hollow cylindrical body corresponds to the pressing member and its urging member, and the conductive rubber corresponds to the conductive body.

In the present invention, the elastic switch 1 having such a basic structure is fixed as shown by the solid line in FIG. 1 in the vertical frame (fixed frame) 2 of the automatic sliding door installation portion, or as shown by the phantom line in FIG. The door 3 is attached to the outer surface of the vertical frame 4 over substantially the entire length. The elastic switch 1 is connected at its upper end with a cord 7 to a door drive controller 6 installed on the upper horizontal frame 5a or the upper frame 5b of the fixed door 3. Reference numeral 8 in FIG. 1 indicates a movable door.

2 to 5 show a modified example of the elastic switch 1 and a mounting structure for the fixed frame 2 or the vertical frame 3 thereof. According to the mounting example of the elastic switch 1 shown in FIG. 2, the switch 1 has a plate-like engaging member with a rib 10a on one surface of the hollow cylindrical body made of silicon rubber having a substantially elliptical cross section. An elastic switch body 10 having a lengthwise direction 10b and a pair of conductive rubbers 11 attached to the inner wall surface of the elliptical hollow portion of the elastic switch body 10 so as to face each other with a predetermined gap therebetween. Become. A T-shaped groove 9 for fitting the engaging member 10b is formed in the switch mounting portion of the fixed frame 2 (or the vertical frame 4) to which the elastic switch 1 is mounted. The groove depth of the portion of the T-shaped groove 9 into which the engaging member 10b is fitted is set to be slightly deeper than the thickness of the engaging member 10b, and between the bottom of the groove 9 and the engaging member 10b. A foam rubber plate 10c is interposed in the space formed in the above, and the engaging member 10b is always urged outward.

The elastic switch structure shown in FIG. 3 has already been described. That is, a pair of elastic switch structures is formed on the inner wall surface of the elliptical hollow portion of the hollow cylindrical body 1a made of a synthetic rubber material such as silicon rubber and having a substantially elliptical cross section. The conductive rubber 1b is attached to face the entire length, and the elastic switch 1 is attached to the outer surface of the vertical frame 2 (vertical frame 4) over almost the entire length with an adhesive.

In the elastic switch 1 shown in FIG. 4, the switch body 12 is made of a long plate material having a T-shaped cross section, and the vertical frame 2 (vertical frame 4) to which the switch 1 is attached has a square cross section. The switch 2 and the slit 2a in which the leg 12a of the switch body 12 is slidably fitted over the entire length of the portion of the vertical frame 2 (vertical frame 4) to which the switch 1 is attached. A box-shaped space portion 2b for accommodating the plate portion 12b of the main body 12 is formed. The plate portion 12b of the switch body 12 is housed in the box-shaped space 2b, and the compression spring 13 is interposed between the bottom surface of the box-shaped space 2b and the back surface of the plate 12b. At the same time, the conductive plate members 14 are provided so as to face each other.

FIG. 5 shows a further modified mounting structure of the elastic switch 1 of the present invention. The elastic switch 1 has a long box-shaped main body 15 which is entirely made of a rigid material such as aluminum alloy, It is composed of a touch member 16 having a substantially T-shaped cross section, a compression spring 13, and a pair of conductive plate members 14. The box-shaped main body 15 is divided into two chambers by a partition 15a, and the partition 15a and the outside. On the surface portion of the touch member 16, the end portions of the leg portions 16a of the touch member 16 and the plate portion 16b are fitted, respectively, and guide openings 15b and 15c are formed for slidingly guiding the box-shaped body 15 inward and outward. The compression spring 13 is interposed between the partition 15a and the plate portion 16b, and the conductive plate material 14 is attached and fixed to the bottom surface of the box-shaped body 15 and the end surfaces of the leg portions 16a, respectively. Has been done. The elastic switch 1 having such a structure is attached by an adhesive over substantially the entire length of the outer surface of the vertical frame 2 (vertical frame 4).
