  • Door stop
    Patent number: 8118336
    Abstract: A doorstop includes a flange connected to a floor contacting portion. The flange is deflectable under transverse pressure. During operation, a door-engaging end portion of the flange contacts a vertical face of a door. Upon deflection, the end portion drops below the vertical face to allow the door to close. In some embodiments, a doorstop includes a spring member and a flange. The spring member includes an arc-shaped portion having a rest curvature and a floor contacting end portion. The arc-shaped portion is deflectable to an arc with less curvature under transverse pressure and returns to the rest curvature upon removal of the transverse pressure. The flange includes a door-engaging end portion and a different attached portion. The attached portion is attached to the arc-shaped portion of the spring member such that the flange is substantively tangent to the arc-shaped portion of the spring member along the attached portion.
