A screen frame element, such as for a security door or window, includes a base; first and second flanges defining a channel and first and second opposing support surfaces; an anchoring member connected to the second flange by a deformable pivot region and extending into the channel at an acute angle relative to the first support surface; and a seat at an inner edge of the first supporting surface substantially opposite the pivot region. The anchoring member is configured to engage the folded edge of a screen sheet, such that, when the screen sheet is drawn away from the base with sufficient force to overcome a yield strength of the pivot region, the anchoring member is configured to rotate about the pivot region to grip part of the screen sheet between the anchoring member and the seat.

A main tilting door for the closure of an access opening of a room comprises two fixed uprights and one fixed crosspiece associable with each other to define a fixed frame. The fixed uprights comprise vertical sliding guides; two movable uprights and two movable crosspieces associable with each other to define a movable frame; tilting movement means comprising: two lateral supporting arms each having a first end which can be hinged to an intermediate area of the movable uprights and a second end which can be hinged to a top of the fixed uprights; two sliding supports movable along the vertical sliding guides; a plurality of panels associable with the movable frame; wherein at least one of said movable uprights and said movable crosspieces comprises a sliding track and a plurality of cursors movable along the sliding track, the panels being associable with the cursors.

An intelligent window allowing ventilation has an outer frame, a sliding frame, an upper locking rod, a lower locking rod, a driving module, a power supply module, and a switch assembly. The sliding frame is slidably mounted in the outer frame. The switch assembly controls the driving module to selectively drive the upper locking rod and the lower locking rod to two locking positions respectively, two ventilation positions respectively or two unlocking positions respectively. Since no handle is needed, an appearance of the intelligent window is neat and scenery outside the intelligent window would not be sheltered. In addition, by actuating the switch module to electrically drive the upper locking rod and the lower locking rod, a user is able to switch the intelligent window to a locked state, a ventilation state or a unlocked state. It is labor-saving and simple in operation.

A system for improving the alignment of building product frame members. The system includes a first and second clip member each with an arcuate edge releasably positioned into a channel within the opposed frame members. A longitudinally extending banding strap looped through openings in both first and second clip member. The first end of the longitudinally extending banding strap is inserted into a banding strap tensioning apparatus and tension is applied to the first end as well as to a longitudinally disposed segment of the banding strap that is also inserted into the banding strap tensioning apparatus. Once the specified span is achieved, the overlapping first end and longitudinally disposed segment are bonded together using the banding member tensioning apparatus thereby preventing movement of the first and second frame members away from one another. Sealant is applied to the frame members and the banding strap clip members are removed.

The invention is a method, an apparatus and a kit of parts for assembling a universal frame with at least two jambs, a lintel and a sill. The resulting frame is suitable for any size of opening and any size of door, with the option to include single doors or double doors as well as side screens and/or side lights. The frame is typically assembled by cutting the jambs (and optionally the sill and/or lintel) to a selected size, attaching keys to each end of each jamb and inserting the keys into keying channels in the sill and lintel.
