Abstract:
A frame assembly (1) and a method for installing a window pane (3) in an opening (5) of a panel (7). The assembly (1) includes an outer frame (9) having connecting devices (15) and an abutment member (17). The assembly (1) also includes an inner frame (19) provided with first connecting devices (25).

The assembly (1) also includes locking device (28) having at least one flexible element (31) cooperating with one of the frames (9, 19) for locking the locking device (28) in locking position, and at least one contacting element (33) for holding the window pane (3) in position with aid of the abutment member (17) when the locking device (28) is in the locking position.
Abstract:
A safety braking device configured for use with the counterbalancing system of a garage door. The safety braking 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.

Abstract:
A device for bending an extremity of a torsional spring. The device includes a base plate; at least one flange projecting from the base plate; at least one bulge projecting from the at least one flange; a lever arm pivotally mounted onto the at least one flange about a first pivot axis; and at least one cam pivotally mounted onto the lever arm about a second pivot axis. The lever arm is operable between first and second positions and each cam has a contact surface being positioned for operatively cooperating with a corresponding bulge. Prior to the bending operation, the extremity of the torsional spring is inserted between a given bulge and the contact surface of a corresponding cam when the lever arm is in the first position. In operation, the extremity of the spring is bent about the given bulge by the contact surface of the corresponding cam when the contact surface is urged towards the bulge and forced about the same over the extremity of the spring as the lever arm is operated into the second position. The device enables an easier, simpler and more cost effective way of bending an extremity of a torsional spring, without the use of heat for bending the spring tail, and may be easily transportable from one site to another. Moreover, the device can be used for bending the extremities of torsional springs having different wire sizes.
Abstract:
A cable failure device for a cable-operated door operated by a tensioned cable, the cable-operated door having a movement guided along a fixed structure, such as a guide rail. The cable failure device is configured for cooperating with the tensioned cable so as to immobilize the cable-operated door with respect to the fixed structure in the event of a loss of tension in the cable. The cable failure device included a support bracket for mounting the cable failure device onto the door, a guiding assembly operatively mounted for guiding the movement of the door along the fixed structure, and a braking assembly operatively mounted onto the support bracket, and operable between a rest position where the guiding assembly is allowed to guide the door along the fixed structure, and an operable position triggered by a given loss of tension detected in the tension cable where the braking assembly engages a portion of the fixed structure for braking movement of the cable-operated door with respect to the fixed structure. The cable failure device also includes a safety arm operatively connected to the braking assembly and cooperating with the tensioned cable so as to detect the given loss of tension. The safety arm is operable between a safety configuration where it is positioned over at least one fastener of a corresponding hole of the support bracket when there is still a given tension in the tensioned cable, for preventing a user from removing the support bracket from the door, and a retracted configuration where the safety arm is positioned away from the fastener when the given tension is no longer present in the cable, thereby enabling the user access to the fastener. Thus, the cable failure device is configured for immobilizing the door in the event of a loss of tension and for preventing a user from removing the device from the door when there is still tension in the cable.
