Abstract
Official abstract text for this publication.
An elevator door bypass apparatus, configured to bypass a landing door or a car door at a time of an inspection of an elevator, includes: a door mode selector switch configured to switch a door mode between a normal operation and a bypass operation; a bypass target selector switch configured to switch between bypassing of the landing door and bypassing of the car door; and a bypass relay configured to, in a case that the door mode has been switched to the bypass operation by the door mode selector switch, bypass the landing door when the bypassing of the landing door has been selected by the bypass target selector switch, and bypass the car door when the bypassing of the car door has been selected by the bypass target selector switch.
First claim
Opening claim text (preview).
The invention claimed is: 1. An elevator door bypass apparatus, which is configured to bypass a landing door or a car door at a time of an inspection of an elevator, the elevator door bypass apparatus comprising: a door mode selector switch configured to switch a door mode between a normal operation and a bypass operation; a bypass target selector switch configured to switch between bypassing of the landing door and bypassing of the car door; and a bypass relay configured to, in a case where the door mode has been switched to the bypass operation by the door mode selector switch, bypass the landing door when the bypassing of the landing door has been selected by the bypass target selector switch, and bypass the car door when the bypassing of the car door has been selected by the bypass target selector switch. 2. The elevator door bypass apparatus according to claim 1 , wherein, in the bypass relay, an a-contact for a relay for bypassing the door to be bypassed and a b-contact for a relay different from the relay for bypassing the door to be bypassed, are connected to each other in series. 3. The elevator door bypass apparatus according to claim 1 , wherein, in a circuit in a case where the door mode has been switched to the normal operation by the door mode selector switch, a b-contact for a relay for bypassing the door to be bypassed and a b-contact for a relay different from the relay for bypassing the door to be bypassed are connected to each other in series. 4. The elevator door bypass apparatus according to claim 1 , wherein, in the bypass relay, a circuit provided on the landing door side and a circuit provided on the car door side are disconnected from each other. 5. The elevator door bypass apparatus according to claim 2 , wherein, in a circuit in a case where the door mode has been switched to the normal operation by the door mode selector switch, a b-contact for a relay for bypassing the door to be bypassed and a b-contact for a relay different from the relay for bypassing the door to be bypassed are connected to each other in series. 6. The elevator door bypass apparatus according to claim 2 , wherein, in the bypass relay, a circuit provided on the landing door side and a circuit provided on the car door side are disconnected from each other. 7. The elevator door bypass apparatus according to claim 3 , wherein, in the bypass relay, a circuit provided on the landing door side and a circuit provided on the car door side are disconnected from each other. 8. The elevator door bypass apparatus according to claim 5 , wherein, in the bypass relay, a circuit provided on the landing door side and a circuit provided on the car door side are disconnected from each other.
