Patent number: 5240216Abstract: Novel angled flag brackets for use with tracks for sectional overhead garage doors are disclosed. The novel angled flag brackets of the present invention are uniquely designed to permit the vertical and horizontal tracks to be uniquely adjusted in both vertical and horizontal directions at the time of assembly and installation so that the assembled and installed tracks will be plumb, level or square. The novel angled flag brackets further permit end bearing plates of torsion spring systems to be directly mounted thereto when door jambs are too short so that the end bearing plates will not remain free-standing following installation.Type: GrantFiled: May 24, 1991Date of Patent: August 31, 1993Assignee: Clopay CorporationInventors: Tony Y. Lin, James R. York, Mark W. Westerfield

Patent number: 5129441Abstract: Novel compressible flexible hinge assemblies for connecting abutting panel sections of upward acting or sectional doors, such as garage doors, are disclosed. More particularly, abutting panel sections of an upward acting door are hingedly connected together economically and in a weather-tight relationship by a flexible hinge assembly which can be easily installed without the use of tools by snapping it into predesigned elongated slots in the abutting panel sections from the rear or interior side of the door. When assembled, a compressible flexible hinge assembly of the present invention provides a smooth, flush back surface on the rear or interior side of an upward acting door and eliminates the unsightly appearance associated with conventional metal hardware heretofore used to hinge abutting panel sections of upward acting doors.Type: GrantFiled: February 25, 1991Date of Patent: July 14, 1992Assignee: Clopay CorporationInventors: Alan R. Leist, Thomas E. Youtsey

Patent number: 5084039Abstract: Novel thermoplastic sheet materials for permitting positionable and repeated repositionable use of tape fasteners therewith without experiencing substnatial loss of tape adhesion therebetween are disclosed. A novel thermoplastic sheet material generally comprises an ethylene polymer and an anti-popoff polymer in an effective amount for increasing and substantially maintaining the tape adhesion. The increase in and substantial maintenance of the tape adhesion is accomplished without adversely affecting the properties or cost of the thermoplastic sheet material. A preferred formulation for producing the novel thermoplastic sheet material comprises polyethylene as the ethylene polymer and a polypropylene or alpha-methyl styrene as the anti-popoff polymer. The novel thermoplastic sheet materials are especially suitable for use as films which can be used as backsheets in absorbent articles, such as, disposable diapers, bandages, surgical dressings or drapes and catamenial pads.Type: GrantFiled: June 7, 1989Date of Patent: January 28, 1992Assignee: Clopay CorporationInventors: Leopoldo V.

Patent number: 4546029Abstract: A plastic film having a random embossed matte finish is provided. The random embossed matte film may be wound very easily into rolls and the roll contour achieved has superior uniformity. In addition, the film provides relatively equal tape adhesion and gloss properties on both sides which make it especially suitable for use in articles such as disposable diapers or underpads. Another advantageous property which renders it especially suitable for diaper conversion operations is its very low degree of edge curl. The thin film provides a totally different appearance as compared to conventional diaper films in that the overall appearance is a dull matte finish, but nonetheless having slight sparkles of brilliance throughout the surface, and it further provides a softer feel.Type: GrantFiled: June 18, 1984Date of Patent: October 8, 1985Assignee: Clopay CorporationInventors: Leopoldo V. Cancio, Pai-Chuan Wu

Patent number: 4523620Abstract: A combination window shade and clutch assembly is provided to prevent over-tensioning of the spring motor of the window shade. The clutch assembly includes spool means connected to one end of the spring motor and cup means, both movable along the window shade shaft. The spool means and cup means are provided with clutch means in the form of mating, tapered locking surfaces adapted to engage one another. The cup means engages retaining means formed in the rotatable housing of the window shade so that rotation of the housing is transmitted to the spool means through the cup means while their locking surfaces are in engagement.Type: GrantFiled: January 17, 1983Date of Patent: June 18, 1985Assignee: Clopay CorporationInventor: Robert M. Mortellite
