Combined door stopper and hinge assembly

Claim 1

In a combined door stopper and hinge assembly including a first and a second hinge leaf, a hinge pin pivotally interconnecting said hinge leaves for relative rotation about a hinge axis, a torsion spring having a body portion affixed to said first hinge leaf and a pair of bent ends forming spring arms, means connecting one of said spring arms with said first hinge leaf, a stop member formed upon said second hinge leaf, and a roller mounted upon the other of said spring arms in a position to operatively engage said stop member during pivotal movement of said hinge leaves relative to each other, said torsion spring being carried in said first hinge leaf in such a manner that said hinge leaves may be swung to turn freely relative to each other over a predetermined angle of rotation prior to engagement of said stop means by said roller, said torsion spring operating to create a spring force resisting further relative rotation between said hinge leaves when said roller engages said stop means, said stop means being configured to permit further relative rotation between said hinge leaves upon application to one of said hinge leaves of a force tending to overcome the stopping force created by engagement between said roller and said stop means, the improvement wherein: at least one of said hinge leaves is formed as a segment of a continuous rolled hinge section; said first hinge is formed with a stop surface having defined therein a longitudinal groove extending parallel to said hinge axis, said groove being defined between a pair of sides extending generally transversely to said stop surface with one of said sides extending at an angle of about 43* relative to said stop surface; said body portion of said torsion spring is securely mounted upon said first hinge leaf to extend within said longitudinal groove; and locking protuberances in the form of stamped portions of said first hinge leaf are formed in the stop surface of said first hinge leaf to extend transversely of said groove to partially overlap said torsion spring for locking said torsion spring in position within said groove to secure said torsion spring against movement in an axial direction relative to said first hinge leaf.
