Abstract

A door closer system having a door closer that includes at least one sensor configured to sense an operating characteristic or condition relating to the door closer including a position or speed of displacement of at least a portion of the door closer or an associated entryway device. The sensor(s) can also provide information relating to the performance or condition of one or more components of the door closer, such as the operation of a backcheck mechanism, as well as tracking the number of door cycles. Information obtained by the sensor(s) of the door closer system can be communicated to a lockset device of an entryway control system. The lockset device can be configured to communicate information received from the door closer system to an access control system, which can in turn provide the communicated information to a management system.

First claim

The invention claimed is:

1. A method of operating an entryway control system for the operation of an entryway device, the entryway system comprising a door closer operable to move the entryway device and an access control device operable to selectively retain the entryway device in a closed position, the method comprising:
by the access control device, wirelessly receiving from the door closer information relating to one or more operating characteristics of the door closer as sensed by a sensor of the door closer; and
by the access control device, wirelessly transmitting the information relating to one or more operating characteristics to an access control system.

2. The method of claim 1 , further comprising:
by the sensor of the door closer, generating the information relating to one or more operating characteristics; and
by a wireless transceiver of the door closer, transmitting to the access control device the information relating to one or more operating characteristics.

3. The method of claim 1 , wherein the one or more operating characteristics comprises at least one of a position of a portion of the door closer or a displacement speed of the portion of the door closer.

4. The method of claim 1 , further comprising transmitting, from the access control device to the door closer, instructions to adjust at least one of the one or more operating characteristics of the door closer.

5. The method of claim 4 , further comprising, by the access control device, receiving the instructions from the access control system, wherein the transmitting the instructions is performed in response to the receiving the instructions.

6. The method of claim 1 , wherein the access control device comprises a lockset device including a lock mechanism operable to selectively lock the entryway device in the closed position.

7. A method of operating an entryway control system for the operation of an entryway device, the entryway system comprising a door closer operable to move the entryway device, the method comprising:
by the door closer, generating information relating to at least one operating characteristic of the door closer;
by the door closer, wirelessly transmitting to an access control device, by a wireless transceiver, the information relating to at least one operating characteristic of the door closer;
by the door closer, wirelessly receiving instructions from the access control device, by the wireless transceiver, to adjust a selected operating characteristic of the at least one operating characteristic; and
by the door closer and in response to receiving the instructions, adjusting the selected operating characteristic according to the instructions.

8. The method of claim 7 , wherein the access control device is operable to selectively retain the entryway device in a closed position.

9. The method of claim 7 , wherein the access control device is a gateway of an access control system.

10. The method of claim 7 , further comprising:
by the access control device, receiving the information relating to at least one operating characteristic of the door closer;
by the access control device, generating the instructions; and
by the access control device, transmitting the instructions to the door closer.

11. The method of claim 7 , further comprising, by the access control device, transmitting to an external device the information relating to at least one operating characteristic of the door closer.

12. The method of claim 11 , wherein an access control system comprises the external device.

13. The method of claim 7 , wherein the at least one operating characteristic comprises at least one of:
a position of the door closer or the entryway device; and
a displacement speed of the door closer or the entryway device.

14. An entryway control system for the operation of an entryway device, the entryway control system comprising:
a door closer comprising a closer body, a sensor configured to detect an operating characteristic of the door closer, and a first wireless transceiver positioned in the closer body and configured to wirelessly transmit information relating to the operating characteristic; and
an access control device operable to control access through the entryway device, the access control device comprising a second wireless transceiver operable to receive the information relating to the operating characteristic;
wherein at least one of the access control device or the door closer is configured to wirelessly transmit the information relating to the operating characteristic to an external device.

15. The entryway control system of claim 14 , wherein the access control device further comprises a lock mechanism operable to selectively lock the entryway device in a closed position.

16. The entryway control system of claim 14 , wherein the access control device is configured to wirelessly transmit the information relating to the operating characteristic via the second wireless transceiver.

17. The entryway control system of claim 14 , wherein the access control device is further configured to transmit to the door closer instructions pertaining to the operating characteristic; and
wherein the door closer is configured to adjust the operating characteristic according to the instructions.

18. The entryway control system of claim 14 , wherein each of the first wireless transceiver and the second wireless transceiver comprises at least one of a WIFI transceiver or a Bluetooth transceiver.

19. The entryway control system of claim 14 , further comprising an access control system comprising the external device;
wherein the access control system is configured to transmit to the access control device instructions relating to operation of the door closer;
wherein the access control device is configured to transmit the instructions to the door closer; and
wherein the door closer is configure to operate according to the instructions.
