Abstract
An overhead opening door lock device for use with existing types of door systems having horizontally hinged panels carried on rollers confined within channeled roller tracks is attached on the interior side of the door and fixes the door in position relative to the roller track. One leg of a U-shaped device is inserted in the hollow interior of a tube that serves as an articulation axis for a pair of hinged panels. The other leg of the U-shaped device penetrates a suitably positioned aperture in the web of the adjacent channeled roller track. A shear pin or padlock shank may be inserted through an aperture in a tip portion of the other leg that projects past the outside plane of the roller track web.
Claims13
A locking appliance for a portal closure comprising a substantially integral unit of parallel first and second arm members joined by a bight member, said second arm member being of greater length from said bight member than said first arm member and having a transverse aperture through a distal end portion of said second arm opposite from said bight member.
A method of securing the position of a portal closure comprising a plurality of parallel panels supported by rollers that are confined to translation between track channels that are separated by a track web, said panels being secured to hollow axle tubes for articulation about a substantially horizontal axis and said track web having at least one transverse aperture, said method comprising the steps of:
- providing a substantially integral, U-shaped appliance having first and second, substantially parallel, arms linked by a bight section, said second arm being of greater length than said first arm and said first arm having a cross-sectional configuration for penetrating a hollow interior of said closure axle tube, a distal end portion of said second arm having a cross-sectional configuration for penetration said track web aperture;
- and,
- simultaneously inserting said first arm of said U-shaped appliance into the hollow interior of said closure axle tube while inserting a distal end of said second arm through said track web aperture.
The combination of a removable portal cover and an appliance to inhibit translation of said cover, said portal cover comprising a plurality of parallel panels supported by rollers that are confined to translation between track channels that are separated by a track web, said panels being secured to hollow axle tubes for articulation about a substantially horizontal axis, said track web having at least one transverse aperture;
- said appliance comprising a substantially integral, U-shaped member having first and second, substantially parallel arms linked by a bight section, said second arm being of greater length than said first arm and said first arm having a cross-sectional configuration for penetrating a hollow interior of said hollow axel tube, a distal end portion of said second arm having a cross-sectional configuration for penetration of said web aperture;
- said appliance being combined with said portal cover by the simultaneous presence of said first arm within the hollow interior of said hollow axel tube and of said second arm distal end portion within said web aperture whereby translation of said panels and rollers along said track is restrained
