Abstract
A bottom bracket for an overhead garage door having a spring tension assisted lift system. The bottom bracket has protrusions that interlock with mating slots in the stile of the garage door bottom panel thus preventing the bracket from detaching from the garage door when the bracket is attached to the spring under tension, even if the bracket fastening screws are removed.
Claims26
An overhead garage door bottom bracket for assisting the door lift in a spring tensioned system comprising:
- a garage door bottom bracket;
- first means for releasably securing said bracket to the door bottom;
- second means for connecting said bracket to a door lifting spring under tension;
- and
- third means for releasably interlocking said bracket to the door bottom, said third means adapted to interlock said bracket with the door bottom when said bracket is connected to the lift spring under tension and to be easily released from the door bottom when said bracket is not connected to the lift spring under tension.
An overhead garage door bottom bracket for assisting the door lift in a spring tensioned system comprising:
- first and second substantially perpendicularly intersecting planar surfaces;
- a ring formed from and substantially perpendicular to said first planar surface for securing a standard door roller to said bottom bracket;
- at least one slot in said first planar surface to permit passage of at least one threaded fastening device for releasably securing said bottom bracket to a garage door;
- an elongated body extending from said second planar surface for securing said bracket to a door lifting spring under tension;
- and
- at least one male protrusion having a narrow throat and a bulbous head on said second planar surface for interlocking said bottom bracket to at least one female receptacle on the door bottom through sliding interference fit thereby preventing said bracket from releasing from said door bottom when said bracket is secured to said spring under tension.
An overhead garage door bottom bracket for assisting the door lift in a spring tensioned system comprising:
- first and second substantially perpendicularly intersecting planar surfaces;
- a ring formed from and substantially perpendicular to said first planar surface for securing a standard door roller to said bottom bracket;
- at least one slot in said first planar surface to permit passage of at least one threaded fastening device for releasably securing said bottom bracket to a garage door;
- an elongated body extending from said second planar surface for securing said bracket to a door lifting spring under tension;
- and
- at least one female receptacle on said second planar surface for interlocking said bottom bracket to at least one male protrusion having a narrow throat and a bulbous head on the door bottom through sliding interference fit thereby preventing said bracket from releasing from said door bottom when said bracket is secured to said spring under tension.
An overhead garage door bottom bracket assembly for assisting the door lift in a spring tensioned system comprising:
- a garage door bottom panel;
- and
- a garage door bottom bracket having first and second substantially perpendicularly intersecting planar surfaces, a ring integrally formed from and substantially perpendicular to said first planar surface for securing a standard door roller thereto, at least one slot in said first planar surface to permit passage of at least one threaded fastening device for releasably securing said bottom bracket to said bottom panel, an elongated body extending from said second planar surface for securing said bracket to a door lifting spring under tension, and means for releasably interlocking said bracket to the door bottom, said means adapted to interlock said bracket with the door bottom when said bracket is connected to the lift spring under tension and to be easily released from the door bottom when said bracket is not connected to the lift spring under tension.
