Abstract
A hinge which includes a mounting flange assembly pivotally coupled to a strap assembly. The strap assembly includes a strap extending from a cylinder portion having a coupling end with a vertically extending octagonal channel therethrough. The hinge also includes an elongated cam follower having a lower cam follower portion and lower cam follower with an upper cam follower portion having a round exterior surface. A cap seals the top opening of the channel. The cap has an annular angle-corrugated shaped sidewall extending to a circular top plate. The angle-corrugated shaped sidewall has eight equally spaced projections corresponding to the eight internal corners of the octagonal channel to resist the relative movement or deflection of or between the strap and the flange.
Claims12
A hinge comprising,
- a mounting flange assembly having a cam-spring assembly with a cylindrical spring housing;
- a strap assembly pivotally coupled to said mounting flange assembly, said strap assembly including a strap having at least one strap mounting hole and a coupling end having a longitudinally extending channel therein configured to receive said cylindrical spring housing, said channel having a polygon configuration with a select number of interior corners, and
- a cap having an angle-corrugated shaped sidewall extending from a top plate, said angle-corrugated shaped sidewall having a select number of projections equal in number to said select number of interior corners of said channel, said angle-corrugated shaped sidewall being positioned between and in contact with said cylindrical spring housing and said channel,
- whereby the proper alignment between the cylindrical spring housing and the channel is maintained by the angle-corrugated shaped sidewall of the cap.
A hinge comprising,
- a mounting flange assembly having a cam assembly including an upper portion with a cylindrical shape;
- a strap assembly pivotally coupled to said mounting flange assembly, said strap assembly including a polygonal shaped channel in which is positioned said upper portion of said cam assembly, said polygonal shaped channel being defined by a select number of internal sides and internal corners, and
- a cap coupled to said strap assembly, said cap having an annular sidewall composed of a series of radially extending elongated projections equal in number to said select number of internal sides and internal corners, said annular sidewall being positioned between said cylindrical shaped upper portion of said cam assembly and said polygonal shaped channel.
A hinge comprising,
- a mounting flange assembly having a cam assembly including an upper portion with a cylindrical shape;
- a strap assembly pivotally coupled to said mounting flange assembly, said strap assembly including a channel positioned about said upper portion of said cam assembly to define a gap between said channel and said upper portion of said cam assembly, said channel being defined by a select number of internal corners, and
- a cap mountable to said strap assembly, said cap having an undulating sidewall having a radial array of peaks wherein each said peak is positioned within said gap in register with one said corner.
