Assignee:
Illinois Tool Work Inc. - Glenview IL
International Classification:
E04B 700
US Classification:
52 57
Abstract:
A flexible end cap includes at least one flexible membrane, such as a rubber sheet, for covering the end of the roof rib, having a top peripheral portion and a bottom peripheral portion. At least one frame member is attached to at least a portion of the top peripheral portion of the flexible membrane for supporting the membrane in a sealing relationship with the roof rib. At least a portion of the bottom peripheral portion, such as the portion for covering a ridge profile, includes at least two sealing ribs wherein a cross-sectional height of one rib is larger than a cross-sectional height of the other rib. The sealing ribs with the larger cross-sectional height allow the end cap to accommodate varying designs of roof rib profiles formed by adjacent sheets of roof panels.
Wall Anchor Accommodating Fasteners Of Varying Thread Diameters
US Patent:
5558479, Sep 24, 1996
Filed:
May 19, 1995
Appl. No.:
8/445274
Inventors:
James W. McElderry - Schaumburg IL
Assignee:
Illinois Tool Works Inc. - Glenview IL
International Classification:
F16B 2500
F16B 3712
F16B 3712
US Classification:
411178
Abstract:
A wall anchor uses splines on an interior surface of a cylindrical body to accommodate fasteners having different thread diameters. The splines are configured in types. A first type includes at least one spline protruding centrally at a narrow angle, while a second type also includes at least one spline protruding centrally at a wider angle. When a fastener, such as a #6 or #8 sheet metal screw (SMS), is inserted into the wall anchor, the first type of spline will primarily engage the #6 SMS, while the second type of splines are only partially implemented. When a #8 SMS, which has a larger thread diameter than a #6 SMS, is inserted into the wall anchor, both the first and second types of splines are engaged to facilitate retention of the SMS.
