FRAME ASSEMLBY

Abstract

A frame assembly supporting an overhead door has a horizontal header connected to upright columns or posts with splice assemblies. Fasteners mounted on the columns cooperate with retainers on the splice assemblies to position and connect the columns to the header. Hinge assemblies pivotally mount the door on the header for movement between open and closed positions.

DETAILED DESCRIPTION OF THE OVERHEAD DOOR AND FRAME ASSEMBLY

[0020] A building 9, shown in FIG. 1, has a doorway or opening to allow a vehicle to move into and out of the interior of the building. Examples of building 9 include aviation hangers, automotive shops, farm shops, commercial buildings, warehouses and manufacturing plants. An overhead door 10 mounted on a frame assembly 11 is movable between an upright closed position and a horizontal open position. Frame assembly 11 has a horizontal header 12 attached to upright columns or legs 13 and 14. Header 12 and columns 13 and 14 are steel tubular members. Door 10 is moved between open and closed positions with linear actuators, such as hydraulic cylinders 16 and 17 or electric motor operated screws. Spherical bearing assemblies 18 and 19 connect the rod ends of hydraulic cylinders 16 and 17 to lower side members 29 and 33 of door 10. The dead ends of hydraulic cylinders 16 and 17 are pivotally connected to cylindrical supports 21 and 22 secured to columns 13 and 14 of frame assembly 11. A hydraulic fluid pump (not shown) operatively connected to opposite ends of hydraulic cylinders 16 and 17 functions to control the flow of hydraulic fluid to and from hydraulic cylinders 16 and 17 whereby hydraulic cylinders 16 and 17 selectively move door 10 to its open and closed positions. An example of a hydraulic fluid system for a hydraulically operated overhead door with hydraulic cylinders is disclosed in U.S. Pat. No. 6,883,273. A linear actuator having a motor operated screw is disclosed in U.S. Pat. No. 6,742,303.

[0021] As shown in FIG. 2, door 10 has a rectangular door frame 23 supporting sheathing 24 and trim. Frame 23 comprises tubular steel horizontal members 26, 27, and 28 secured with welds to tubular steel upright members 29, 30, 31, 32 and 33. Sheathing 24 is attached to members 26 to 33 with fasteners or an adhesive. A plurality of hinge assemblies 34, 35, 36, 37 and 38 pivotally mount door frame 23 to header 12 of frame assembly 11 for movement about a horizontal axis 39. Horizontal axis 39 established by hinge assemblies 34 to 38 is laterally of the outside surface of header 12 and parallel to the length of header 12. Hinge assemblies 34 to 38 uniformly distribute the weight of door 10 on header 12 and maintain door 10 level during its opening and closing movements.

[0022] Proceeding to FIGS. 4 and 5, frame assembly 11 has splice assemblies 40 and 41 attached to opposite ends of header 12. Splice assemblies 40 and 41 telescope or fit into the open upper ends of columns 13 and 14. A plurality of bolts 57, 58, 59, 67, 69 and 82 secure columns 13 and 14 to splice assemblies 40 and 41.

[0023] Splice assembly 40 has a body 42 comprising a flat member having an upper end extended into header 12. Body 42 extends downward from the end of header 12. A first pair of outside ribs or flanges 43 are secured to the outside of body 42. A second pair of inside ribs or flanges 44 and 45 are secured to the inside of body 42. Ribs 43, 44 and 45 are secured with welds to body 42. A horizontal plate 46 joined to the upper ends of ribs 43 to 45 and located in engagement with and secured to the bottom of header 12 retains splice assembly 40 in a downward 90 degree relationship with respect to header 12.

[0024] Splice assembly 41, shown in FIGS. 5 to 11, has a body 47 having an upper end extended into header 12. A first pair of upright ribs or flanges 48 and 49 are secured to the inside surface of body 47. A second pair of upright ribs or flanges 51 and 52 are secured to the outside surface of body 47. Ribs 48, 49, 51 and 52 reinforce opposite sides of body 47 and space body 47 from the side walls of column 14. The inside surface of body 47 has hexagonal cavities accommodating retainers or nuts 54, 55 and 56. Welds secure nuts 54, 55 and 56 to body 47. Other types of threaded members can be secured to body 47 for accommodating bolts 57, 58 and 59. Body 42 has a plurality of retainers or nuts 68, 81 and 83 similar to nuts 54, 55 and 56. A horizontal plate 53 secured to the upper ends of ribs 48, 49, 51 and 52 and located in engagement with and secured to the bottom of header 12 retains splice assembly 41 in a downward 90 degree relationship with respect to header 12.

[0025] 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 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. Column 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 column wall 13B. A plurality of bolts contact body 42 to prevent column 13 from moving forward and rearward relative to splice assembly 40.

[0026] 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.

[0027] 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. Bolts 57, 58 and 59 are turned tight to secure column 14 to splice assembly 41 and move inner wall 14A of column 14 into firm engagement with ribs 48 and 49. Outer wall 14C of column 14 is located in vertical alignment with the first outer end of header 12. The outer surface of wall 14C of column 14 is located in the same or common vertical plane as the first end of header 12. The first end of header 12 and column 14 is located in close relationship with the adjacent surface of building wall 70.

[0028] As shown in FIG. 13, bolts 61, 63 and 65 threaded through nuts 62, 64 and 66 engage a side of body 47. Nuts 62, 64 and 66 are secured by welds adjacent holes in column 14. Bolts 61, 63 and 65 are turned to force body 47 into surface engagement with the inside of wall 14B of column 14. The outside surface of wall 14B of column 14 is vertically aligned with the outside front surface of header 12. The outside surface of wall 14B of column 14 and the outside front surface of header 12 are located in the same or common vertical plane.

[0029] Splice assembly 41 secured to column 14 with bolts 57, 58 and 59 and 61, 63 and 65 retains column 14 in a vertical position relative to header 12. Column 14 is prevented from moving laterally and vertically relative to header 12. Bolts 57, 58 and 59 and 61, 63 and 65 also permit adjustment of column 14 in two directions relative to the end of header 12.

[0030] Hinge assembly 35, shown in FIG. 15, has a tubular member or sleeve 72 secured to an arm 73. Arm 73 extend across the top of header 12. Welds secure arm 73 to header 12. Left and right angle supports 74 and 76 located adjacent opposite ends of a sleeve 72 accommodate a pin 77. Pin 77 extended horizontally through sleeve 72 pivotally mounts sleeve 72 and arm 73 on pin 77. Supports 74 and 76 are welded to the horizontal top door frame member 26. A square head 78 secured to an end of pin 77 prevents rotation of pin 77 relative to supports 74 and 76. Head 78 and cotter key 80 on opposite ends of pin 77 limit axial movement of pin 77 relative to supports 74 and 76. Grease zerks 86 mounted on sleeve 72 are used to apply grease to the inside cylindrical surface of sleeve 72 and outside surface of pin 77.

[0031] The foregoing drawing and description of the frame assembly for an overhead door is one embodiment of the invention. Persons skilled in the art of overhead doors can make changes and modifications in structures and materials of the door, frame assembly and hinge assemblies without departing from the door, frame assembly and hinge assemblies defined in the claims.
