Abstract

Disclosed is a system for an elevator door of an elevator car, wherein a controller controls the elevator door to travel in a proximate direction when closing and travel in a distal direction when opening, the system including: a panel that forms an exterior surface of an elevator door, the panel including a front surface extending in a widthwise direction between a proximate end and an opposing distal end to form a front surface of the elevator door, the panel including a proximate end surface extending in a depthwise direction to form a proximate end surface of the elevator door, the proximate end surface of the panel comprising a resilient portion that is capable of engaging a sensor in the panel when the elevator door is closing, and thereafter the controller instructs the elevator door to reopen.

First claim

What is claimed is:

1. A system for an elevator door of an elevator car, wherein a controller controls the elevator door to travel in a proximate direction when closing and travel in a distal direction when opening, the system comprising:
a panel that forms an exterior surface of an elevator door, the panel including a front surface extending in a widthwise direction between a proximate end and an opposing distal end to form a front surface of the elevator door, the panel including a proximate end surface extending in a depthwise direction to form a proximate end surface of the elevator door,
the proximate end surface of the panel comprising a resilient portion, and wherein when the elevator door is closing, the controller renders a plurality of determinations including: a first determination to monitor for a communication from a sensor in the door panel, wherein the communication is indicative of the resilient portion deflecting in the distal direction; a second determination to reopen the elevator door upon detecting deflection in the distal direction; and wherein the controller transmits instructions to the elevator to effect the second determination;
wherein the sensor is in a cavity in the door panel, the cavity being defined by: (i) the front surface of the panel; (ii) the proximate end surface of the panel; (iii) a first return surface of the panel that is depthwise offset from the front surface of the panel and connected to the proximate end surface of the panel; and (iv) a first internal surface of the panel that is distally offset from the proximate end surface of the panel and connected to both the front surface of the panel and the first return surface of the panel; wherein the resilient portion extends distally into the cavity through the proximate end surface of the panel to operationally communicate with the controller; and
wherein the proximate end of the panel includes a proximate J-channel formed by (i) the front surface of the panel, (ii) the first internal surface of the cavity, and (iii) a distal portion of the first return surface that extends distally from the cavity.

2. The system of claim 1 wherein the resilient portion forms a strip extending in a heightwise direction for the door panel.

3. The system of claim 1 wherein the resilient portion is an elastomer.

4. The system of claim 1 wherein the sensor is a pressure sensor.

5. The system of claim 1 wherein the distal end of the panel includes a distal end J-channel formed by (i) the front surface of the panel, (ii) a distal end surface of the panel that is connected to the front surface of the panel and extends parallel to the proximate end surface of the panel, and (iii) a second return surface of the panel that is connected to the distal end surface of the panel and offset from the front surface of the panel in a same depthwise direction as the first return surface.

6. The system of claim 5 wherein the distal end surface of the panel forms a distal end surface of the elevator door, and wherein the first return surface and second return surface are coplanar, whereby the proximate J-channel and distal J-channel are configured to fixedly connect the panel to the elevator door.

7. The system of claim 1 wherein a unitary sheet of metal forms the panel.

8. The system of claim 1 including an elevator door and the panel fixedly connected to the elevator door.

9. A method for an elevator controller in an elevator system to control an elevator door while the elevator door is closing,
wherein the controller controls the elevator door to travel in a proximate direction when closing and travel in a distal direction when opening, and the system includes a panel that forms an exterior surface of an elevator door, the panel including a front surface extending in a widthwise direction between a proximate end and an opposing distal end to form a front surface of the elevator door, the panel including a proximate end surface extending in a depthwise direction to form a proximate end surface of the elevator door, and the proximate end surface of the panel includes a resilient portion, and
the method including: rendering a first determination to monitor for a communication from a sensor in the door panel, wherein the communication is indicative of the resilient portion deflecting in the distal direction; rendering a second determination to reopen the elevator door upon detecting deflection in the distal direction; and transmitting instructions to the elevator to effect the second determination;
wherein the sensor is in a cavity in the door panel, the cavity being defined by: (i) the front surface of the panel; (ii) the proximate end surface of the panel; (iii) a first return surface of the panel that is depthwise offset from the front surface of the panel and connected to the proximate end surface of the panel; and (iv) a first internal surface of the panel that is distally offset from the proximate end surface of the panel and connected to both the front surface of the panel and the first return surface of the panel; wherein the resilient portion extends distally into the cavity through the proximate end surface of the panel to operationally communicate with the controller; and
wherein the proximate end of the panel includes a proximate J-channel formed by (i) the front surface of the panel, (ii) the first internal surface of the cavity, and (iii) a distal portion of the first return surface that extends distally from the cavity.

10. The method of claim 9 wherein the resilient portion forms a strip extending in a heightwise direction for the door panel.

11. The method of claim 9 wherein the resilient portion is an elastomer.

12. The method of claim 9 wherein the sensor is a pressure sensor.

13. The method of claim 9 wherein the distal end of the panel includes a distal end J-channel formed by (i) the front surface of the panel, (ii) a distal end surface of the panel that is connected to the front surface of the panel and extends parallel to the proximate end surface of the panel, and (iii) a second return surface of the panel that is connected to the distal end surface of the panel and offset from the front surface of the panel in a same depthwise direction as the first return surface.

14. The method of claim 13 wherein the distal end surface of the panel forms a distal end surface of the elevator door, and wherein the first return surface and second return surface are coplanar, whereby the proximate J-channel and distal J-channel are configured to fixedly connect the panel to the elevator door.

15. The method of claim 9 wherein a unitary sheet of metal forms the panel.

16. The method of claim 9 including an elevator door and the panel fixedly connected to the elevator door.
