The wireless non-contact switch detects movement of human body in the beam-shaped detection are which extends from the upper area on the wall toward the floor surface, and controls opening and closing of the automatic door. Regardless of the height of the location of the movement, as long as it is in the detection area, the switch detects the movement of different height location in the detection area. Therefore, regardless of the difference of regulation between each states, it can be operated at any height of the movement.

Wireless non-contact switch for automatic doors

The present invention provides a swing door opening/closing detection system capable of accurately discriminating an opening/closing position of door main bodies to accordingly prevent the malfunction of the door main bodies. The swing door opening/closing detection system includes: door main bodieswhich are rotatably provided and which rotate to open/close relative to an opening part; driving partsrotary driving the door main bodies; a control partcontrolling the rotary driving of the door main bodiesby the driving parts; a sensing part() attached to the door main bodiesto sense a person or an object in sensing areas on paths of the door main bodies; a deformation partdeforming according to the rotational operation of the door main bodies; and a discriminating part() which discriminates the opening/closing position of the door main bodiesbased on a deformation amount of the deformation partto control the control partbased on the discrimination result.

Swing door opening/closing detection system

Sensor(s) may be such that light-projecting component(s) and light-receiving component(s) are arranged therein. Furthermore, such sensor(s) may be provided with optical path varying means for varying projected light optical path(s) and/or received light optical path(s) so as to physically vary overlapping zone(s) in which the projected light optical path(s) and the received light optical path(s) at least partially overlap. The optical path varying means may carry out adjustment of optical sensitivity by increasing the extent(s) of the overlapping zone(s) when carrying out detection with respect to zone(s) distant from such sensor(s) and/or decreasing the extent(s) of the overlapping zone(s) when carrying out detection with respect to zone(s) proximate to such sensor(s).

Optical detection sensor

Sensor(s) may be such that light-projecting component(s), at which light is irradiated from one or more light-projecting elements by way of lens group(s); and light-receiving component(s), at which at least a portion of light irradiated from such light-projecting component(s) is incident on one or more light-receiving elements by way of lens group(s) after having been reflected, are arrayed therein. Lens group(s) is/are divided into a plurality of lens sets comprising a plurality of lenses. A plurality of lens sets are arranged so as to be inclined in V-shaped fashion such that a plurality of lenses occupy respectively symmetric locations.

Sensor

Door sensor(s) may be attached to a door body or bodies of automatic swing doors. The door sensor(s) may be equipped with door position detectors including geomagnetic sensor(s), the sensor(s) being itself or themselves capable of detecting position(s) occupied by the door body or bodies during opening and/or closing thereof. During opening and/or closing of the door body or bodies, determination may be made as to whether detected object(s) are object(s) intended for detection; and in the event that object(s) are object(s) intended for detection, opening and/or closing of the door body or bodies may be stopped, slowed, and/or reversed in correspondence to detected position(s) occupied by the door body or bodies during opening and/or closing thereof.
