Abstract
An overhead door and frame has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar. The splice assemblies connect the upright columns to the header. Hinges pivotally mount an overhead door to the header to allow hydraulic cylinders to selectively move the overhead door to an open position and a closed position.
Claims21
An overhead door and frame comprising:
- an overhead door,
- a frame,
- hinges connected to the overhead door and the frame for supporting the overhead door on the frame for movement between a generally horizontal open position and an upright closed position,
- the frame comprising:
- a header having a first end and a second end opposite the first end,
- a first tripod leg connected to the first end of the header,
- said first tripod leg comprising:
- a first base,
- a first upright tubular column secured to the first base,
- a second upright tubular column secured to the first base, said second upright tubular column being parallel to the first upright tubular column and laterally spaced from the first upright tubular column,
- a first upright I-bar secured to the first base, said first upright I-bar being spaced from the first upright tubular column and spaced from the second upright tubular column,
- at least one first transverse member secured to the first upright tubular column and secured to the second upright tubular column,
- at least one first rib secured to the at least one first transverse member and the first upright I-bar for connecting the one first transverse member to the first upright I-bar,
- a second tripod leg connected to the second end of the header,
- said second tripod leg comprising:
- a second base,
- a third upright tubular column secured to the second base,
- a fourth upright tubular column secured to the second base, said fourth upright tubular column being parallel to the third upright tubular column and laterally spaced from the third upright tubular column,
- a second upright I-bar secured to the second base, said second upright I-bar being spaced from the third upright tubular column and spaced from the fourth upright tubular column,
- at least one second transverse member secured to the third upright tubular column and secured to the fourth upright tubular column,
- at least one second rib secured to the at least one second transverse member and secured to the second upright I-bar,
- a first linear actuator connected to the overhead door and the at least one first transverse member, and
- a second linear actuator connected to the overhead door and the at least one second transverse member,
- said first linear actuator and said second linear actuator being concurrently operable to selectively move the overhead door relative to the frame between the upright closed position and the generally horizontal open position and from the generally horizontal open position to the upright closed position.
