Protection device for an overhead door
View Patent ↗An impact protection device for an overhead comprising an elongated beam shaped to at least partially span the door. The beam includes box members at the ends there of which releasably interfit with channel members at a closed position of the door to laterally secure the beam with respect to a support surface adjacent the door, (when to absorb and transmit lateral impact forces applied against the beam away from the door and against the support surface. The door and beam are connected so that elevational movement of the door will result in corresponding elevational motion of the beam.
1. An overhead door guard apparatus, comprising:
at least one elongated impact absorbing beam;
at least one channel adapted to be secured to a support separate from the at least one beam and positioned to releasably receive at least one part of said at least one beam when the at least one beam is in a closed door position;
at least one lifting member and at least one lifting receiver which are each mounted to a respective one of a door and said at least one beam, and which engage for elevationally moving the beam in response to elevational movement of the door;
a stop configured to be mounted to a surface separate from the beam for blocking said beam from striking said door at an open position of said door;
wherein the at least one beam includes a front surface that is substantially vertical, an inclined surface leading angularly upwardly from the front surface to an upwardly curved surface that leads to a top surface.
2. The apparatus of claim 1 wherein the at least one beam includes at least one end having a box shape for reception by said at least one channel.
3. An overhead door protection apparatus comprising:
at least one beam of impact resisting construction extending across an overhead door in an overhead door opening;
at least one guide not mounted upon the door, said at least one guide being positioned to releasably receive said at least one beam when the beam and overhead door are moved into a closed door position;
at least one lifting member and at least one lifting receiver which are each mounted to a respected one of the door and said at least one beam, and which engage for elevationally moving the beam in response to elevational movement of the door;
a stop configured to be mounted to a surface separate from the beam for blocking said beam from striking said door at an open position of said door;
wherein the at least one beam includes a front surface that is substantially vertical, an inclined surface leading angularly upwardly from the from surface to an upwardly curved surface that leads to a top surface.
4. The apparatus of claim 3 wherein the at least one beam includes at least one end having a box shape for reception by the at least one guide.
