Abstract

A door latch includes a latch bolt and strike plate capable of transferring electricity therebetween. The latch bolt and strike plate may each include one or more complementary electrical leads such that electrical power and/or electrical signals may flow between the complementary electrical leads, when the electrical leads are in contact with one another.

First claim

What is claimed is:

1 . A latch bolt assembly for use with a strike plate, the latch bolt assembly comprising:
a latch bolt configured to transition between an open position and a closed position, wherein, in the open position, the latch bolt is disengaged from the strike plate and, in the closed position, the latch bolt is engaged within the strike plate; and at least one latch bolt electrical lead disposed on the latch bolt and positioned such that the at least one latch bolt electrical lead establishes an electrical connection with at least one complementary strike plate electrical lead disposed on the strike plate when the latch bolt is in the closed position.

2 . The latch bolt assembly of claim 1 , wherein the latch bolt includes at least one groove configured to receive a corresponding at least one latch bolt electrical lead.

3 . The latch bolt assembly of claim 1 , further including an insulator disposed on the latch bolt and configured to insulate the at least one latch bolt electrical lead from the latch bolt.

4 . The latch bolt assembly of claim 1 , further including at least one spring cooperating with a corresponding at least one lath bolt electrical lead, the at least one spring configured to bias the corresponding at least one latch bolt electrical lead towards the at least one complementary strike plate electrical lead.

5 . The latch bolt assembly of claim 1 , in combination with a sensor cooperating with the latch bolt, the sensor configured to sense whether the latch bolt is in the open position or the closed position.

6 . A strike plate for use with a latch bolt assembly, the strike plate comprising:
a strike plate body; an opening disposed in the strike plate body and configured to accept a latch bolt of the latch bolt assembly; a tab disposed at the opening; and at least one strike plate electrical lead disposed on the tab and positioned such that the at least one strike plate electrical lead establishes an electrical connection with at least one complementary latch bolt electrical lead disposed on the latch bolt when the latch bolt is within the opening.

7 . The strike plate of claim 6 , further including an insulator disposed on the tab and configured to insulate the at least one strike plate electrical lead from the strike plate.

8 . The strike plate of claim 6 , further including at least one spring cooperating with a corresponding at least one strike plate electrical lead, the at least one spring configured to bias the corresponding at least one strike plate electrical lead towards the at least one complementary latch bolt electrical lead.

9 . The strike plate of claim 6 , in combination with a sensor cooperating with the latch bolt, the sensor configured to sense whether the latch bolt is disposed within the opening.

10 . A door latch comprising:
a latch bolt assembly configured to be attached to a door, the latch bolt assembly having a latch bolt; a strike plate configured to be attached to a door frame, the strike plate having a strike plate body, an opening disposed in the strike plate body and configured to accept the latch bolt, and a tab disposed at the opening, wherein the latch bolt is configured to transition between an open position and a closed position, wherein the latch bolt is configured to be within the opening when the latch bolt is in the closed position; and at least one latch bolt electrical lead disposed on the latch bolt and at least one complementary strike plate electrical lead disposed on the tab, wherein the at least one latch bolt electrical lead establishes an electrical connection with at least one complementary strike plate electrical lead when the latch bolt is within the opening.

11 . The door latch of claim 10 , wherein the at least one latch bolt electrical lead and the at least one strike plate electrical lead are configured to transmit electrical power to one or more external electronic devices when the latch bolt is within the opening in the strike plate body.

12 . The door latch of claim 11 , wherein the at least one latch bolt electrical lead and the at least one strike plate electrical lead are configured to transmit electrical power to at least one of an ultracapacitor and a battery when the latch bolt is within the opening in the strike plate.

13 . The door latch of claim 11 , wherein the at least one latch bolt electrical lead and the at least one strike plate electrical lead are configured to transmit electrical power from at least one of an ultracapacitor and a battery when the latch bolt is within the opening in the strike plate.

14 . The door latch of claim 10 , wherein the at least one latch bolt electrical lead and the at least one strike plate electrical lead are configured to transmit one or more electrical signals to one or more electronic devices when the latch bolt is within the opening in the strike plate.

15 . The door latch of claim 11 , in combination with the door, the door latch being coupled to the door, wherein the door comprises a solar power generator and wherein the at least one latch bolt electrical lead and the at least one strike plate electrical lead are configured to transmit electrical power from the solar power generator when the latch bolt is within the opening in the strike plate.
