Abstract: 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.

Abstract: A plug for use in a counterbalancing mechanism of a cable-operated door. The plug is used for operatively connecting an overhead shaft to a torsion spring co-axially mounted thereon. The plug includes a cylindrical collar and a cylindrical flange. The cylindrical collar has opposite first and second portions and is provided with a hooking slot for hooking a free end of the torsion spring thereon, and the torsion spring having a segment coaxially mounted about the first portion of the collar. The cylindrical flange is rigidly affixed to the second portion of the collar and is used for transferring a torque between the torsion spring and the overhead shaft when the flange is securely fixed about the overhead shaft.

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 first connecting devices (25) cooperate with the connecting devices (15) of the outer frame (9) for disengageably connecting the outer and inner frames (9, 19). 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: According to the present invention, there is provided a window set comprising a plastic sheet having a first portion which is thermoformed, and a second portion provided with a silk-screen printed pattern. The window set comprises a support member for providing support to the plastic sheet. Both the plastic sheet and the support member are made of a material allowing a least partial transmission of light. The window set also comprises a securing means for securing the plastic sheet to the support member. There is also provided a method for making the window set of the present invention.

Abstract: A plug mounted at one end of a torsional spring operatively connected to an overhead shaft of a counterbalancing mechanism of a garage door, wherein the plug comprises projecting interlocking means able to cooperate with corresponding matching means of a mating part of the counterbalancing mechanism, so that when the interlocking means of the plug are inserted into the corresponding matching means and when tension is applied to the torsional spring, the interlocking means interlock with said matching means of the mating part, thereby preventing the plug from being readily removed therefrom. The projecting interlocking means thus act as safety means because they provide an automatic locking mechanism which make the plug operate as a safety device as well.

Abstract: A plug for use in a counterbalancing mechanism of a cable-operated door. The plug is used for operatively connecting an overhead shaft to a torsion spring co-axially mounted thereon. The plug includes a cylindrical collar and a cylindrical flange. The cylindrical collar has opposite first and second portions and is provided with a hooking slot for hooking a free end of the torsion spring thereon, the torsion spring having a segment coaxially mounted about the first portion of the collar. The cylindrical flange is rigidly affixed to the second portion of the collar and is used for transferring a torque between the torsion spring and the overhead shaft when the flange is securely fixed about the overhead shaft The plug is characterized in that the collar is eccentrically mounted about the overhead shaft, thereby allowing the plug to be used when the radial space between the plug and the overhead shaft is limited and also preventing the overhead shaft from being damaged by the free end of the torsion spring.
