The specific embodiment
Followingly describe with reference to the safety device of illustrated embodiment to elevator doorway of the present invention.
First embodiment
Fig. 1 to Fig. 3 represents first embodiment of the safety device of elevator doorway of the present invention, and a round door device with midsplit type that opens and closes elevator doorway is example.
As shown in Figure 1, in the present embodiment, the gangway 1 of elevator is by the round door 2A of midsplit type, and 2B opens and closes.This round door 2A, 2B is by not shown suspention guide rail (Hanger Rail) suspention that is arranged on 1 top, gangway.In addition, be fixed on and be formed with not shown door groove (Sill Groove) on the door 3 on the framework 11, round door 2A, the bottom of 2B is inserted in the door groove, round door 2A, the on-off action of 2B is by suspention guide rail and the guiding of door groove.And, round door 2A, the on-off action of 2B is by controlling device for doors 4 controls.
Be provided with the obstacle detector 6 that clear (for example elevator passenger) 5 is arranged on the door 3 for detection of gangway 1 in the round door device of the midsplit type of present embodiment.
This obstacle detector 6 is by being installed in round door 2A, and the side's of 2B door is closed first on the side end 2a and detected with device 7 and be installed in the door of closing the opposed the opposing party of side end 2a with door and close second on the side end 2b and detect with device 8 formation.As shown in Figure 2, first detect to have with device 7 and send ultrared light projector 9, the second detections and have the ultrared light-receiving device 10 that reception is sent from light projector 9 with device 8.
In the present embodiment, above-mentioned light projector 9 and light-receiving device 10 towards being variable, carry out variable control by controlling device for doors 4, the round door 2A that can judge according to the software in controlling device for doors 4, the opened and closed positions of 2B is with putting towards changing into toward each other of light projector 9 and light-receiving device 10.
That is to say, round door 2A, the opened and closed positions information of 2B is imported in the controlling device for doors 4, according to this round door 2A, the opened and closed positions information of 2B, with the round door 2A that controlling device for doors 4 is judged, the opened and closed positions of 2B correspondingly to light projector 9 and light-receiving device 10 towards changing control, make the mutually opposed toward each other of light projector 9 and light-receiving device 10.Be specifically, at the round door 2A shown in Fig. 3 (a), the opened and closed positions of 2B, this locational round door 2A, the opened and closed positions information of 2B is imported in the controlling device for doors 4, according to this round door 2A, the opened and closed positions information of 2B, with the round door 2A that controlling device for doors 4 is judged, the opened and closed positions of 2B correspondingly to light projector 9 and light-receiving device 10 towards changing control, make the mutually opposed toward each other of light projector 9 and light-receiving device 10.In Fig. 3 (b), equally also can carry out variable control, with the round door 2A shown in Fig. 3 (b), the opened and closed positions of 2B accordingly to light projector 9 and light-receiving device 10 towards changing control, make the mutually opposed toward each other of light projector 9 and light-receiving device 10.
Software in the above-mentioned controlling device for doors 4 has disturbance in judgement quality testing survey device 6 and has or not the judgment means that detects obstacle (for example elevator passenger).
Be specifically, as shown in Figure 4, in the action of closing the door (step S1), when the infrared ray that sends from light projector 9 (step S2) is received by light-receiving device 10 (step S3), this judgment means is judged as does not have obstacle 5 on the door 3, the action (step S4) of proceeding to close the door.In step S4, be judged as door when also not closing fully, return step S1 again and judge.On the other hand, in the action of closing the door (step S1), when the infrared ray that sends from light projector 9 (step S2) is not received by light-receiving device 10, this judgment means is judged as obstacle 5 on the door 3, obstacle detection signal is input in the controlling device for doors 4, the termination action of closing the door makes door oppositely mobile, and action (step S5) just begins to open the door.
According to the present invention, owing to use a pair of infrared rays receiver and light projector device to detect obstacle, so the inspection operation when the confirming operation operation when obstacle detector is installed and maintenance becomes convenient.In addition, even when being used for round door, owing to have the function that turns to control according to the door opened and closed positions, can detect obstacle according to the opened and closed positions of door, so can prevent that the obstacle that does not have possibility to be clamped by the gangway is produced flase drop to be surveyed.
