AUTOMATIC DOOR INSTALLATION
There is disclosed an automatic door installation 100 configured to determine the presence of an obstacle 150 in one or more detection zones remote from a door opening, comprising: at least a first door 104 slidable in a door opening along a horizontal door axis from an open configuration to a closed configuration during a door closing operation; a plurality of transmitter-receiver pairs, each transmitter-receiver pair comprising: a transmitter 116 for transmitting a beam 140 and a receiver 118 for receiving a reflection of the beam, wherein one of the transmitter 116 and the receiver 118 is coupled to the first door so that, in use, the transmitter and receiver move closer together during the door closing operation; wherein the transmitter 116 defines a transmitter axis 120 corresponding to the optical axis of the beam; wherein the receiver 118 has a field of view 142 for receiving the beam, which is oriented around a receiver axis; and wherein the transmitter axis 120 and the receiver axis 122 are configured so that the beam and the field of view overlap to define a detection zone for the transmitter-receiver pair in at least one operational configuration of the door installation. At least one of the transmitter axis 120 and the receiver axis 122 is inclined with respect to the horizontal plane and the transmitter 116 is vertically spaced apart from the receiver 118.
