Abstract

A door operator system may include a sectional door, an opener operably coupled to the sectional door to move the sectional door via a roller assembly operably coupling the sectional door to a rail assembly to enable the sectional door to transition between an open state and a closed state via the roller assembly carrying the sectional door in the rail assembly, and a plurality of accessories associated with the sectional door or components of the sectional door. The accessories may include at least one powered device having a rechargeable battery that is charged based on inductive charging via an inductive charging assembly.

Claims (46)

1 . A door operator system comprising:

a sectional door;

an opener operably coupled to the sectional door to move the sectional door via a roller assembly operably coupling the sectional door to a rail assembly to enable the sectional door to transition between an open state and a closed state via the roller assembly carrying the sectional door in the rail assembly; and

a plurality of accessories associated with the sectional door or components of the sectional door,

wherein the accessories include at least one powered device having a rechargeable battery that is charged based on inductive charging via an inductive charging assembly,

wherein the sectional door includes at least a first door panel having a first panel accessory and a second door panel including a second panel accessory,

wherein both the first and second panel accessories are powered via the rechargeable battery that is operably coupled to the first and second panel accessories via an on-door power distribution network, and

wherein the rechargeable battery is located on the first panel.

2 . The system of claim 1 , wherein the accessories include one or more on-door accessories, and

wherein the inductive charging assembly comprises a primary charge coil disposed proximate to the sectional door and a secondary charge coil disposed on the sectional door to provide direct current (DC) power to the rechargeable battery via an alternating current (AC) to DC converter.

3 . The system of claim 2 , wherein the rechargeable battery powers a plurality of the one or more on-door accessories.

4 . The system of claim 2 , wherein the one or more on-door accessories include a camera, privacy glass, a display screen, lighting, a sensor associated with the sectional door, or a lock.

5 . The system of claim 2 , wherein the primary charge coil is disposed to be oriented horizontally on the floor, and wherein the secondary charge coil is disposed in a panel of the sectional door that is proximate to the floor and aligned with the primary charge coil when the sectional door is in the closed state.

6 . The system of claim 1 , wherein the accessories include one or more off-door accessories, and

wherein each instance of the one or more off-door accessories includes a primary charge coil disposed in an accessory mount that operably couples to a secondary charge coil of a respective one of the each instance of the one or more off-door accessories.

7 . The system of claim 5 , wherein mains power supplies power to a plurality of off-door accessories and corresponding accessory mounts.

8 . The system of claim 1 , wherein the on-door power distribution network comprises a panel interface between at least the first and second door panels to provide electrical connectivity across the first and second door panels through a transition between the open and closed states of the sectional door.

9 . The system of claim 1 , wherein the sectional door includes at least a first door panel having a first panel accessory and a second door panel including a second panel accessory,

wherein the inductive charging assembly comprises a first primary charge coil disposed off-door proximate to a first secondary charge coil disposed on the first door panel, and

wherein the inductive charging assembly comprises a second primary charge coil disposed off-door proximate to a second secondary charge coil disposed on the second door panel.

10 . The system of claim 9 , wherein the first and second primary charge coils are each operably coupled to a rail of the rail assembly.

11 . The system of claim 1 , wherein at least one of the accessories is an adaptive accessory that has an alternate status or capability based on door position of the sectional door.

12 . The system of claim 11 , wherein the adaptive accessory comprises a camera that pivots as the sectional door change between the open and closed states to provide a view outside the sectional door in both the open and closed states.

13 . A door operator system comprising:

a sectional door;

an opener operably coupled to the sectional door to move the sectional door via a roller assembly operably coupling the sectional door to a rail assembly to enable the sectional door to transition between an open state and a closed state via the roller assembly carrying the sectional door in the rail assembly; and

a plurality of accessories associated with the sectional door or components of the sectional door,

wherein the accessories include at least one powered device having a rechargeable battery that is charged based on inductive charging via an inductive charging assembly,

wherein the accessories include one or more on-door accessories, and

wherein the inductive charging assembly comprises a primary charge coil disposed proximate to the sectional door and a secondary charge coil disposed on the sectional door to provide direct current (DC) power to the rechargeable battery via an alternating current (AC) to DC converter,

wherein the rechargeable battery is one of a plurality of rechargeable batteries associated with respective different instances of the one or more on-door accessories, and

wherein each of the plurality of rechargeable batteries is operably coupled to the secondary charge coil to be recharged via the secondary charge coil.

14 . An on-door power distribution network for powering accessories of a door operator system without wires extending on-door from off-door, the door operator system comprising a sectional door and an opener operably coupled to the sectional door to move the sectional door, the on-door power distribution network comprising:

a secondary charge coil disposed at a portion of the sectional door that is proximate to a primary charge coil disposed adjacent to the sectional door when the sectional door is in a closed position;

an alternating current to direct current (AC-DC) converter to convert AC output from the secondary charge coil to DC;

a plurality of accessories associated with the sectional door or components of the sectional door; and

a rechargeable battery that is charged via the DC converted at the AC-DC converter, the rechargeable battery being associated with one or more of the accessories,

wherein the sectional door includes at least a first door panel having a first panel accessory and a second door panel including a second panel accessory,

wherein both the first and second panel accessories are powered via the rechargeable battery that is operably coupled to the first and second panel accessories via an on-door power distribution network, and

wherein the rechargeable battery is located on the first panel.

15 . The on-door power distribution network of claim 14 , wherein the rechargeable battery powers all of the accessories that are operably coupled to the secondary charge coil.

16 . The on-door power distribution network of claim 14 , wherein the rechargeable battery is one of a plurality of rechargeable batteries that each power respective ones of the accessories that are operably coupled to the secondary charge coil.

17 . The on-door power distribution network of claim 14 , wherein the accessories are distributed across different door panels of the sectional door, and

wherein the on-door power distribution network comprises a panel interface between each of the different door panels to provide electrical connectivity across the different door panels through a transition between open and closed states of the sectional door.

18 . The on-door power distribution network of claim 14 , wherein the accessories are distributed across different door panels of the sectional door, and

wherein each of the different door panels has a corresponding instance of the secondary charge coil to power all accessories located on respective ones of the each of the different door panels.
