Hinge assemblies pivotally mount the door on the header for movement between open and closed positions.

Description

FIELD OF INVENTION

The overhead door and frame assembly is in the art of a door for a structure having a doorway that is selectively opened and closed with a door mounted on a frame assembly. The door is a one-piece door mounted with hinges to a header of the frame assembly. Hydraulic cylinders operate to swing the door between an upright closed position to a generally horizontal open position allowing vehicles and equipment to be moved through the doorway into and out of the structure.

BACKGROUND OF THE INVENTION

Buildings have large openings or doorways for accommodating trucks, tractors, airplanes and equipment to be moved into and out of the interior spaces in the buildings. Common types of conventional doors used to open and close the doorways are horizontally sliding doors and two-piece center hinged doors known as bi-fold doors. An example of a bi-fold door is disclosed by M. L. Schweiss in U.S. Pat. No. 6,866,080. A plurality of hinges pivotally mount the bi-fold door to the header of the building whereby the entire weight of the bi-fold door is accommodated by the header of the building. These doors require a larger opening than is required to accommodate the open door. The overall vertical height of the doorway is compromised to compensate for the folded bi-fold door. Overhead doors are used to open and close doorways to maximize the useable space of the doorway of the structures. An example of a hydraulically operated overhead door is disclosed by D. J. Kerkvliet in U.S. Pat. No. 6,883,273. The overhead doors are mounted with hinges on load bearing frames that are separate from the building structures whereby the weight or load of the overhead doors is not subjected to the building headers or side jambs. The load bearing frames are known as free standing headers having a header and upright legs. The legs are field welded on opposite ends of the header. The legs must be straight, flush and flat with the header to maintain the overhead doors in open and closed positions. Welding fixtures and tooling are used to maintain the alignment of the legs relative to the header during the field welding operation. The welding of the legs to the header requires welding skills, supplies, labor and time. R. Peterson in U.S. Patent Application Publication No. 2011/0225895 discloses a door hinged to a frame secured to a building structure and a method of assembly of a door on a plurality of cross members. The frame has a header connected to the upright posts. Connectors join the posts to the header. Fasteners such as bolts secure the connectors to the posts. Hinges pivotally connect the door to the header of the frame. Welds are also disclosed as securing the fasteners to the upright posts.

SUMMARY OF THE INVENTION

The invention is a frame assembly for supporting an overhead door operable to move between a generally upright closed position and a generally horizontal open position. The invention includes a method of connecting a header to the frame assembly. The frame assembly has a horizontal header supported by upright columns. Splice assemblies connect the columns to opposite ends of the header. The splice assemblies include cooperating retainers and fasteners that align the columns with the header and maintain the columns straight, flush and in the same upright plane of the header. A plurality of hinge assemblies pivotally connect a top member of the door frame to the header. Linear actuators such as hydraulic cylinders or motor driven screws connected to the door and columns operate to swing the door between an upright closed position and a generally horizontal open position. The frame assembly supports the weight of the door and absorbs the forces subjected to the door during the opening and closing of the door thereby eliminating most if not all weight and forces on the adjacent building structure. Each splice assembly has an upright body having a wall and opposite end edges. A plurality of upright ribs attached to the body are retained in a flat surface engagement with a column by adjustable fasteners connecting the column to the body. The fasteners include nuts secured to the body and bolts mounted on the column engageable with the nuts. In use, the bolts are turned to move the column into alignment with the header and secure the column to the splice assembly. A plurality of second adjustable fasteners comprise cooperating nuts and bolts. The bolts engage an edge of the body to hold the opposite edge of the body in engagement with the column concurrently with the engagement of the ribs with this column. The first and second adjustable fasteners retain the splice assembly in engagement with the perpendicular walls of the column. The hinge assemblies have sleeves rotatably mounted on non-rotatable pins. Door members secured to the sleeves are connected to the top member of a door frame. Header members mounted on pins adjacent the sleeves are secured to the header whereby the hinge assemblies support the door on the header of the frame assembly for movement of the door between open and closed positions.

Splice assembly 40 is secured to column 13 with bolts 67, 69 and 82. Nuts 68, 81 and 83 mounted on body 42 accommodate bolts 67, 69 and 82 extended through holes in column 13. Bolts 67, 69 and 82 are turned tight to retain the outer ends of ribs 44 and 45 in engagement with the inside of wall 13A of column 13. The outer wall 13C of column 13 and the adjacent end of header 12 is located in vertical alignment with the second outer end of header 12. Wall 13C has an outer surface located in the same or common vertical plane as the second end of header 12. A bolt 84 threaded through a nut 85 secured to column 13 engages a side of body 42. Bolt 84 is turned tight to hold body 42 in firm contact with the inside of wall 13B of column 13. A plurality of bolts contact body 42 to prevent column 13 from moving forward and rearward relative to splice assembly 40.

Returning to FIG. 2, a plurality of hinge assemblies 34 to 38 pivotally mount door 10 on header 12. Hinge assemblies 34 to 38 have a common horizontal axis 39 allowing hydraulic cylinders 16 and 17 to swing door 10 from an upright closed position to a generally horizontal open position. The open horizontal position of door 10 is shown in FIG. 1. Hinge assemblies 34 to 38 are identical in structure and function. The following description of hinge assembly 35 is applicable to hinge assemblies 34 and 36 to 38 and additional hinge assemblies used to pivotally mount door 10 on header 12.

Proceeding to FIGS. 12 and 14, columns 13 and 14 are inserted into splice assemblies 40 and 41 secured to opposite ends of header 12. A plurality of bolts 57, 58 and 59 extended through holes in column 14 are threaded into nuts 54, 55 and 56.
