Abstract
The invention includes a clasp that can be mounted to the roller track of an overhead door and a shim that can be mounted to the overhead door or the shaft of the roller. The clasp includes a portion for attaching to the roller track and a blocking portion that is secured in proximate location to the inner surface of the overhead door. When the overhead door is in a closed position, the shim and the blocking portion are engaged thereby encouraging the overhead door towards the door frame. Multiple clasp and shim assemblies can be mounted to the overhead door to improve the seal between the overhead door and the door frame.
Claims20
A structure for encouraging the outside face of an overhead door towards a door frame, the overhead door being an integral part of a roller track assembly, the structure comprising the combination of:
- a roller track clasp having a roller track clasping portion that can be attached onto a roller track at a position approximate to a roller shaft and guide roller assembly when the overhead door is in a first position, the roller shaft and guide roller assembly comprising a roller mounted to a roller shaft, the roller shaft being mounted to the overhead door and the roller residing in the interior of the roller track, and a block portion facing the interior surface of the overhead door;
- and
- a shim that is mounted onto the roller shaft in such a manner that the shim and the block portion are engaged when the overhead door is in the first position, thereby encouraging the overhead door towards the door frame.
A structure for encouraging the outside face of an overhead door towards the facing of a door frame, the overhead door being an integral part of a roller track assembly which includes a roller track and a roller shaft and guide roller assembly, the roller shaft and guide roller assembly comprising a roller mounted to a roller shaft, the roller shaft being mounted to the overhead door and the roller residing in the interior of the roller track, the structure comprising the combination of:
- a roller track clasp having a roller track clasping portion that can be attached onto a roller track and a block portion facing the interior surface of the overhead door;
- and
- a shim that is mounted onto the overhead door and independent of the roller shaft in such a manner that when the overhead door is in a first position, the shim engages to the block portion of the roller track clasp, thereby encouraging the overhead door towards the door frame.
A method for encouraging the outside face of an overhead door towards the facing of a door frame, the overhead door being an integral part of a roller track assembly and, on opposing ends of the overhead door, a plurality of roller shaft and guide roller assemblies are fixedly attached thereto, each roller shaft and guide roller assembly comprising a roller mounted to a roller shaft, the method comprising:
- attaching one or more roller track clasps to the roller track assembly, the roller track clasp having a roller track clasping portion and a block portion, the roller track clasps being attached in such a manner that each roller track clasp is associated with one of the plurality of roller shaft and guide roller assemblies by being attached in proximate location with one of the plurality of roller shaft and guide roller assemblies when the overhead door is in a first position;
- and
- attaching a shim to the roller shaft and guide roller assembly that is associated with a roller track clasp, the shim being attached in such a manner that the shim and the block portion are engaged when the overhead door is in the first position, thereby encouraging the overhead door towards the door frame.
