Abstract
A screen panel for a roll-up door is configured to be slidably coupled to the door adjacent a bottom portion of the door. The panel is generally parallel to the bottom portion when installed and movable between a retracted position, wherein a bottom edge of the panel is generally aligned with a bottom edge of the door, and an extended position, wherein the bottom edge of the panel is located below the bottom portion. A biasing device biases the panel toward the retracted position with a biasing force that is sufficient to move the panel to the retracted position only when the panel is positioned in an orientation other than a vertical orientation.
Claims21
A screen panel for a roll-up door, comprising:
- a screen panel configured to be slidably coupled to the roll-up door adjacent a bottom portion of the roll-up door, the screen panel configured to be generally parallel to the bottom portion of the roll-up door when installed and movable between a retracted position, wherein a bottom edge of the screen panel is configured to be generally aligned with a bottom edge of the roll-up door, and an extended position, wherein the bottom edge of the screen panel is configured to be located below the bottom portion;
- and
- a biasing device for biasing the screen panel toward the retracted position with a biasing force;
- wherein the biasing force is sufficient to move the screen panel to the retracted position only when the screen panel is positioned in an orientation other than a vertical orientation.
A screen panel for a roll-up door, comprising:
- a screen panel configured to be slidably coupled to the roll-up door at a bottom portion of the roll-up door, the screen panel configured to be generally parallel to the bottom portion of the roll-up door when installed and movable a limited distance between a retracted position, wherein a bottom edge of the screen panel is configured to be generally aligned with a bottom edge of the roll-up door, and an extended position, wherein the bottom edge of the screen panel is configured to be located below the bottom portion, wherein the screen panel is configured to be internal to the bottom section when in the retracted position;
- and
- a biasing device for biasing the screen panel toward the retracted position with a biasing force;
- wherein the biasing force is insufficient to prevent the screen panel from moving to the extended position while the screen panel is in a vertical orientation, the biasing force being sufficient to move the screen panel to the retracted position when the screen panel is positioned in an orientation other than the vertical orientation.
A screen panel for a roll-up door, comprising:
- a screen panel configured to be slidably coupled to the roll-up door at a bottom portion of the roll-up door, the screen panel configured to be generally parallel to the bottom portion of the roll-up door when installed and movable between a retracted position, wherein a bottom edge of the screen panel is configured to be generally aligned with a bottom edge of the roll-up door, and an extended position, wherein the bottom edge of the screen panel is configured to be located below the bottom portion;
- and
- a biasing device for biasing the screen panel toward the retracted position with a biasing force;
- wherein the biasing force is insufficient to prevent the screen panel from moving to the extended position while the screen panel is in a vertical orientation, the biasing force being sufficient to move the screen panel to the retracted position when the screen panel is positioned in an orientation other than the vertical orientation.
