Abstract:
A tensioning assembly (1) for winding a winding system (5). The tensioning assembly (1) includes a support bracket (9), a collar portion (13), a ratchet wheel (17), and a pawl component (23). The support bracket (9) is connectable to a fixed frame. The collar portion (13) is removably mountable onto a shaft (3) of the winding system (5), and is proximate to the support bracket (9), the collar portion (13) having a securing assembly (15) for removably securing the collar portion (13) onto the shaft (3). The ratchet wheel (17) is securely mounted onto the collar portion (13) and is rotatable therewith, the ratchet wheel (17) being positionable adjacent to the support bracket (9), and being provided with a plurality of teeth (19) and a plurality of corresponding recesses (21). The pawl component (23) is operatively mountable on the support bracket (9) and is moveable with respect to said support bracket (9), the pawl component (23) having an extremity (25) being positioned, shaped and sized with respect to at least one recess (21) of the ratchet wheel (17) for allowing rotation of the shaft (3) along a winding direction (7a), and for blocking rotation of the shaft (3) along an unwinding direction (7b).
Abstract:
A plug (1) for use with a counterbalancing system (3) of a cable-operated door (5). The plug (1) includes flange and collar portions (13,15), the flange portion (13) being connectable to a mounting component (7) of the counterbalancing system (3) in order to allow a torque transfer from a torsion spring (9) to the mounting component (7), and the collar portion (15) being configured for winding into a given end (17) of the torsion spring (9), the collar portion (15) having opposite first and second extremities (19,21), and an outer surface (23) extending between these extremities (19,21), the outer surface (23) of the collar portion (15) being provided with a plurality of threads (25) and a plurality of corresponding recesses (27) each being defined between a pair of adjacent threads (25), each recess (27) being configured for receiving therein a single coil segment (11a) of the torsion spring (9), and being further shaped and sized for preventing another coil segment (11b) of the torsion spring (9) from embarking onto said recess (27).
Abstract:
A plug for operatively connecting a torsion spring onto a corresponding component of a counterbalancing mechanism of a door assembly. The plug includes a connecting portion for removably connecting the plug onto the corresponding component, a substantially cylindrical collar insertable into an end portion of the torsion spring, an anchoring portion disposed on a bottom section of the collar for cooperating with a coil of the end portion of the torsion spring so as to pivotally anchor the collar onto the end portion of the torsion spring, and a clip projecting from a top section of the collar, and being disposed at a location on the collar substantially diametrically opposite from where the anchoring portion is disposed on the bottom section of the collar. The clip is shaped and sized for clasping past an end coil of the torsion spring and operatively engaging with the same
