Abstract
An example door stop mechanism is provided. The door stop mechanism includes a body, a connection member, a spring, and a brake. The spring is coupled to the body and the connection member. The brake is positioned adjacent to the body. The brake moves between an engaged position via a spring force of the spring that causes the body to interact with the brake such that the brake contacts a track of an overhead door and an disengaged position via a force that acts against the spring force to pull the body away from the brake such that the brake moves away from the track to allow the overhead door to move.
Claims18
A door stop mechanism, comprising:
- a bracket comprising a first side and a second side coupled together at a right angle, wherein the first side comprises one or more openings to be connected to a bottom most panel of an overhead door and the second side comprising a first protruding member and a second protruding member;
- a body, comprising:
- a first slot to receive the first protruding member of the bracket;
- a second slot to receive the second protruding member of the bracket;
- and
- a third protruding member, wherein the third protruding member, the first slot, and the second slot are aligned in a vertical direction;
- a connection member, comprising a third slot to receive the third protruding member of the body;
- a spring coupled to the body and to the connection member;
- and
- a brake positioned adjacent to the body, wherein the brake moves between an engaged position via a spring force of the spring that causes the body to interact with the brake such that the brake contacts a track of the overhead door and a disengaged position via a force that acts against the spring force to pull the body away from the brake such that the brake moves away from the track to allow the overhead door to move.

A door stop mechanism, comprising:
- a bracket comprising a first side and a second side coupled together at approximately 90 degrees, wherein the first side comprises one or more openings to be connected to a bottom most panel of an overhead door and the second side comprising a first protruding member and a second protruding member;
- a body, comprising:
- a first slot to receive the first protruding member of the bracket;
- a second slot to receive the second protruding member of the bracket;
- and
- a third protruding member, wherein the third protruding member the first slot, and the second slot are aligned in a vertical direction;
- a connection member, comprising a third slot to receive the third protruding member of the body;
- a spring coupled to the body and to the connection member;
- and
- a brake positioned adjacent to the body;
- a drum;
- and
- a strap coupled to the drum and to the connection member, wherein tension applied to the strap causes the body to move away from the brake to move to a disengaged position such that the brake moves away from a track of the overhead door, and a loss in tension to the strap causes the body to interact with the brake to move the brake to an engaged position such that the brake moves towards the track and contacts the track.

An overhead door system, comprising:
- a track system;
- an overhead door movably coupled to the track system, wherein the overhead door comprises a plurality of panels;
- a shaft located over the overhead door;
- a drum coupled to a first end of the shaft;
- a motor coupled to the first end of the shaft to rotate the shaft to open and close the overhead door and rotate the drum;
- a door stop mechanism coupled to a bottom most panel of the plurality of panels;
- a strap, wherein a first end of the strap is coupled to the drum and a second end of the strap is coupled to the door stop mechanism;
- and
- a bracket coupled to the bottom most panel, wherein the bracket comprises a panel mounting surface and a door stop mechanism mounting surface coupled together perpendicularly, wherein the door stop mechanism mounting surface comprises a first protruding member and a second protruding member, wherein the door stop mechanism comprises:
- a body, comprising a first slot to receive the first protruding member of the bracket, a second slot to receive the second protruding member of the bracket, a third protruding member, and a guide slot, wherein the third protruding member, the first slot, and the second slot are aligned in a vertical direction;
- a strap connection member coupled to the second end of the strap, wherein the strap connection member comprises a third slot to receive the third protruding member of the body;
- a spring coupled to the body and the strap connection member;
- and
- a brake coupled to the second protruding member of the bracket and positioned adjacent to the body, wherein the brake comprises a brake protruding member that is inserted into the guide slot of the body, wherein tension applied to the strap causes the body to move away from the brake and causes the brake to rotate to a disengaged position such that the brake moves away from an exterior surface of the track system, and a loss in tension to the strap causes the body to move towards the brake and causes the brake to rotate to an engaged position such that the brake moves towards the track system and contacts the exterior surface of the track system.
