Abstract

An object of the present application is to obtain a door-pinch detection device and an elevator door device that enable detection of a string-shaped object. Accordingly, the elevator door device of the present application includes: a door panel of an elevator; and a first attachment section and a second attachment section installed on at least either one of a front face or a back face of the door panel, the first attachment section including a pressure sensor, the second attachment section including a repulsive member installed in a manner for the pressure sensor to be housed therein when doors of the elevator are closed, thus enabling adjustment of an angle of the pressure sensor relative to the door panel. Therefore, door-pinch of an alien object can be detected with an improved accuracy.

First claim

The invention claimed is:

1. A door-pinch detection device, comprising:
a first attachment section and a second attachment section attached to at least either side face of a front face or a back face of a door panel of an elevator, the first attachment section including a pressure sensor, the second attachment section including a repulsive member installed in a manner for the pressure sensor to be housed therein; and
at least either one of a first angle adjustment section provided in the first attachment section to adjust an attachment angle of the pressure sensor with respect to the door panel for installation or a second angle adjustment section provided in the second attachment section to adjust an attachment angle of the repulsive member with respect to the door panel for installation, wherein
the pressure sensor is configured to detect an alien object.

2. The door-pinch detection device according to claim 1 , wherein
the first angle adjustment section includes an elongated hole made in the first attachment section,
the second angle adjustment section includes an elongated hole made in the second attachment section, and
the first attachment section or the second attachment section is fixed to the door panel with the attachment angle adjusted by adjusting a position for a fitting to penetrate the elongated hole, the fitting penetrating the elongated hole and being fixed at a hole made in the front face or the back face of the door panel.

3. The door-pinch detection device according to claim 1 , wherein
the first angle adjustment section includes an adjustment member with an elastic force provided in the first attachment section,
the second angle adjustment section includes an adjustment member with an elastic force provided in the second attachment section, and
each of the adjustment members causes the pressure sensor or the repulsive member to swingably move.

4. The door-pinch detection device according to claim 3 , wherein the adjustment member is a resin.

5. The door-pinch detection device according to claim 3 , wherein the adjustment member is a spring.

6. The door-pinch detection device according to claim 3 , wherein a repulsive force of the adjustment member is larger than a motion sensitivity of the pressure sensor and smaller than a pressing force applied to a door hitting face of the door panel when doors of the elevator are closed.

7. The door-pinch detection device according to claim 1 , wherein the pressure sensor is installed to project with respect to a door hitting face of the door panel.

8. The door-pinch detection device according to claim 1 , wherein the pressure sensor is installed to retract with respect to a door hitting face of the door panel.

9. An elevator door device, comprising:
a door panel of an elevator;
a door-pinch detection device including a first attachment section and a second attachment section installed on at least either one of a front face or a back face of the door panel, the first attachment section including a pressure sensor, the second attachment section including a repulsive member installed in a manner for the pressure sensor to be housed therein when doors of the elevator are closed; and
an angle adjustment section provided in the door panel to adjust an attachment angle of at least either one of the first attachment section or the second attachment section for installation, where
the pressure sensor is configured to detect an alien object.

10. The elevator door device according to claim 9 , wherein
the third angle adjustment section includes an elongated hole made in at least either one of the front face or the back face of the door panel, and
at least either one of the first attachment section or the second attachment section has a hole penetrating therethrough and is fixed to the elongated hole at an angle relative to a door hitting face of the door panel with a fitting penetrating the hole.

11. The elevator door device according to claim 10 , wherein
the third angle adjustment section includes an adjustment member with an elastic force, and
the adjustment member causes the pressure sensor or the repulsive member to swingably move.

12. The elevator door device according to claim 11 , wherein the adjustment member is a resin.

13. The elevator door device according to claim 11 , wherein the adjustment member is a spring.

14. The elevator door device according to claim 11 , wherein a repulsive force of the adjustment member is larger than a motion sensitivity of the pressure sensor and smaller than a pressing force applied to a door hitting face of the door panel when the doors are closed.

15. The elevator door device according to claim 9 , wherein the pressure sensor is installed to project with respect to a door hitting face of the door panel.

16. The elevator door device according to claim 9 , wherein the pressure sensor is installed to retract with respect to a door hitting face of the door panel.
