  • Brake device for garage doors and the like, kit for assembling the same, and door assembly provided with the brake device
    Publication number: 20070204515
    Abstract: A braking device configured for use with the counterbalancing system of a garage door. The brake device includes a support bracket, a ratchet wheel, a pawl arm, and a biasing spring. The support bracket is rigidly connected to a fixed structure and has a guiding slot. The ratchet wheel is securely mounted about the overhead shaft of the counterbalancing system and has at least one notch. The pawl arm has first and second ends, the first end of the pawl arm being pivotally connected to the support bracket and the second end of the pawl arm cooperating with the guiding slot and being movable with respect to the support bracket along said guiding slot. The first and second ends of the pawl arm are further connected to flanges of a plug on either side of the overhead shaft. The biasing spring is operatively connected between the support bracket and the pawl arm so as to exert a biasing force for biasing the pawl arm towards the ratchet wheel.

  • Wall bracket reinforced with an embossment, overhead door assembly including the same, and method of manufacturing such a reinforced wall bracket
    Publication number: 20050006545
    Abstract: A wall bracket for supporting an overhead door assembly, such as that of garage doors and the like. The wall bracket includes a first portion for fastening onto a fixed structure, such a wall, said first portion extending along a first vertical plane. The wall bracket also includes a second portion for receiving a corresponding component of the door assembly, said second portion extending along a second vertical plane substantially perpendicular to the first vertical plane of the first portion. An important feature of the wall bracket resides in the fact that it further comprises an embossed portion, made integral to the second portion and being shaped and sized for increasing the sectional inertia of the second portion so as to provide said second portion with an reinforcement resistant to warping of said second portion.
