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. The pawl arm is devised so that, an element thereof is adjacent to the ratchet wheel, said element being shaped and sized to be removably insertable into at least one notch of the ratchet wheel so as to block rotation of the ratchet wheel, and thus block rotation of the overhead shaft, in the event of a failure of the counterbalancing system of the door. The brake device further includes a shear pin operatively connectable between the support bracket and the pawl arm for maintaining said pawl arm, prior to installation of the brake device onto the counterbalancing system, in an intermediate configuration between the first and second configurations. The shear pin is made of a specific material being breakable when the pawl arm is rotated with respect to the support bracket when the torsional force of the torsional spring transmitted to said pawl arm via the plus has reached a predetermined value, ensuring namely that a predetermined minimal amount of load is present is said torsional spring for counterbalancing purposes.

Brake device for garage doors and the like, and door assembly including the same

A brake device () is for use with a cable-operated door (), such as garage doors () and the like. The device () is intended to reduce the risk of the door () falling, or at the very least slow down its descent, in the event of a failure in the counterbalancing mechanism of the door (), which is generally represented by a loss of tension in a given tensioned cable () operating the door (). The brake device () includes a support bracket (), and a guiding assembly () and a braking assembly () mounted onto the support bracket (). The braking assembly includes a swivel component () having a braking arm () and a lever portion (), the lever portion cooperating with the tensioned cable () so that in the event of the loss of tension in the cable (), the braking arm () is urged onto an adjacent rail () via a biasing spring () for anchoring a knife () of the braking arm () into the rail () and stopping, or at the very least, slowing down the descent of the door (), with respect to the rail ().

A window framework for mounting a glass pane in an aperture of a panel. The window framework includes an exterior frame having a peripheral wall shaped for fitting with and extending into the aperture. The peripheral wall extends between exterior and interior sides of the panel, and is provided along the periphery thereof with an abutment member adjacent to the exterior side. The wall is also provided with stop means adjacent to the interior side. The window framework also includes removable locking means having a flexible element lockable with the stop means when the locking means is in a locking position. The locking means is also provided with an element for holding the glass pane in position with the aid of the abutment member when the locking means is in the locking position. The window framework further includes a securing means for securing the exterior frame to the panel in the aperture. A method for mounting a glass pane in an aperture of a panel is also provided.

Sliding lock

A security seal for a collar used for tensioning springs in garage door assemblies. A collar typically includes at least one set screw projecting outwardly and at least two winding holes. The security seal of the invention includes a generally longitudinal piece of flexible material having two opposite ends, the opposite ends being provided with a locking system for locking the opposite ends together in a permanent fashion. The seal also has at least one hollow cup adapted to receive the at least one set screw and at least two solid cups, each of the cups being adapted to fit with a corresponding winding hole. The hollow cup and the at least two solid cups are disposed on the security seal so that when the seal is locked above the collar, the hollow cup and the solid cups are in registration with the at least one set screw and the at least two winding holes respectively.
