Abstract
A base member and a fascia are assembled to form a hollow door section which is filled with insulative material. Adjacent sections are coupled along respective longitudinal edges for angular and spatial displacement. The base member is extended from a selected plastic with male and female coupling components extending continuously along respective longitudinal edges. A plurality of mounting members projecting from the lateral edges of the sections matingly and slidably engage the semi-cylindrical guide surface of a tract for reciprocal vertical movement of the door. The door may be partially raised for spatial displacement of the sections whereby flow-through ventilation openings are exposed. In a specific embodiment, a flexible drive screw is rotatably carried within the track for powered operation of the door.
Claims6
A sectional door assembly comprising:
- a) an upper section having a lower longitudinal edge;
- b) a lower section having an upper longitudinal edge;
- c) hinge means for pivotably securing said lower section to said upper section for rotation about a first longitudinal axis;
- and
- d) a guide assembly for affixing said door to a building and allowing reciprocal movement along an upright axis, said guide assembly including
- i) a tubular guide portion securable to said building, said guide portion including a guiding surface,
- ii) a guide member including
- a semi-cylindrical body portion having a guide surface slidably encompassing said guiding surface, and
- attachment means for securing said body portion to said door, said attachment means having a longitudinal axis coinciding with said first longitudinal axis.
