Door sensor and door equipped with such door sensor
First Claim
1. A door sensor comprising:
- at least one door position detector which is attached to at least one door body that can be opened and/or closed and which is capable of detecting at least one position occupied by the at least one door body during opening and/or closing thereof;
at least one object detector which is attached to the at least one door body and which detects a presence and/or an absence of at least one object in at least one detectable zone; and
at least one object determining circuit which receives at least one output from the at least one door position detector and the at least one object detector, and which determines, in correspondence to at least one position occupied by the at least one door body during opening and/or closing thereof, whether at least one object detected by the at least one object detector is at least one object intended for detection,wherein the at least one door position detector is attached to at least one door body capable of being opened and/or closed as a result of rotational motion, and includes at least one sensor which employs geomagnetism to detect at least one angular displacement position of the at least one door body.

Abstract
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.
