Abstract: A toggle insert for receiving a toggle assembly in a steel curtain wall structure is disclosed. The toggle insert is a self-leveling profile requiring no welding for fastening to steel curtain wall structure and further provides a screw tolerance of up to 1 inch for locating and fastening toggle screws during installation of glazing elements to the steel curtain wail structure. The toggle insert includes a horizontal section having a front portion, an intermediate portion and a bottom portion, wherein the front portion includes a central elongated opening measuring between 21 mm and 25 mm sandwiched on either sides by slotted screw race and a pair of threaded set screws for leveling into the slotted screw race that fixes the toggle insert by way of wedging into the steel curtain wall structure.

Abstract: A corner key assembly for a sliding panel system including a panel frame and a movable panel can include a corner key including a distal and proximal end, and a guide chamber being defined in the corner key, the guide chamber extending from the distal end towards the proximal end of the corner key; a guide slidingly movable relative to the corner key, at least a portion of the guide being configured to be positioned in the guide chamber and a portion of the guide being configured to extend from the guide chamber; and a biasing element positioned in the guide chamber between the guide and the proximal end, the biasing element configured to urge a portion of the guide from the guide chamber away from the corner key and into frictional engagement with the panel frame to hold the panel in a desired position relative to the panel frame.

Abstract: A system for adjusting infill panel or operable fenestration frame in an operable fenestration. The system can include a setting block adjustment device and an operable fenestration frame such as a door rail or window sash with glass, acrylic, polycarbonate or other infill material. The setting block adjustment device can include a lug, a threaded fastener, a setting block support plate, and a setting block. The lug is slidably captive within a groove in an outer face of the operable fenestration. The threaded fastener engages a threaded aperture within a blind hole in the lug. The fastener end engages the setting block support plate and setting block to adjust the infill panel.

Abstract: Disclosed is a stretching device for artistic media, which includes a pair of horizontal and vertical frame members. The horizontal frame members and the vertical frame members can be removably connected by means of L-shaped joints to form a rectangular frame. Each of the horizontal frame members and the vertical frame members include an upper flat bar and a lower flat bar slideably attached thereto by means of slide screws. The upper flat bar and the lower flat bar can be brought closer together so as to hold an edge of a piece of paper therebetween by adjusting clamping screws affixed thereto. The upper flat bar and the lower flat bar can be moved away from the horizontal frame member or the vertical frame member by means of stretch knob screws. In one embodiment, the device may be utilized to stretch watercolor paper and prevent the paper from wrinkling.

Abstract: The invention relates to a weight compensation device for a drive of a lifting door, for the position-dependent compensation of the weight force of a door leaf of the lifting door, with a force transmission unit which can be coupled to the drive in order to carry out an opening movement which raises the door leaf and a closing movement which lowers the door leaf, wherein at least one compression spring is provided which is arranged in such a way that it supports the opening movement. The invention also relates to a lifting door, in particular an industrial lifting door, which has a door leaf, with a drive, such as a motor, and with a weight compensation device according to the invention.

Abstract: The present invention essentially comprises an overhead door backup spring system for providing an auxiliary spring counterweight to operate an overhead door shaft upon failure of a spring. The system has an activation unit, a control assembly, an engagement assembly operably associated with the activation unit, and an auxiliary spring engagement assembly operably associated with the control and engagement assemblies. The control assembly has an engagement block engageable with a spring post of the auxiliary spring assembly. The engagement assembly has an engagement post engageable with the spring post to transfer torque from the auxiliary spring to the overhead door shaft. An engaged position has the engagement post not engaged with the spring posts while the engagement block is engaged with the spring post. A non-engaged position has the engagement post engaged with the spring post, and the engagement block not engaged with the spring post.

Abstract: A sliding door assembly includes a sliding door that is slidingly mounted to a top track via one or more top guide assemblies. The sliding door is also slidingly mounted to a bottom track. Each top guide assembly includes a top guide wheel that rotationally mounts to the top guide assembly and engages the top track to guide the sliding door. The guide wheel rotates relative to the top guide assembly about an axis that extends horizontally in a direction perpendicular to a direction of travel of the sliding door. The guide wheel also movably mounts to the top guide assembly so that the guide wheel moves upwardly and downwardly relative to the top guide assembly and sliding door to correct for any variation in the gap between the top and bottom tracks.

Abstract: A window includes a sash movable between closed and open positions while pivoting on a pair of slides which are vertically movable along the respective side posts of an outer frame. For pivotally connecting the sash to each slide, a pair of axially aligned longitudinally spaced sleeves are mounted on the top edge of the sash, one of the sleeves slidably receiving a pivot pin projecting from the slide. Rotatably arranged between the sleeves is an adjustor ring having a key projecting into the interturn spacing of a helical compression spring mounted within the sleeves and secured at one end to the pivot pin. The contact force of the slide on the side post is adjustable by the rotation of the adjustor ring relatively to the sleeves.
