Abstract
A closure assembly is provided including a track and a slidable and pivotable closure member. The closure member is engaged with the track proximate first and second pivots adjacent the pivotable end of the member, the first and second pivots being interconnected by a multiple segment shaft (for example at least two portions) (for example telescoping) which provides for accurate installation, retention, removal, adjustment and alignment of the first and second pivots in a substantially parallel line for pivotally supporting the closure member so that it may be safely and securely pivoted away from the closure assembly. Improvements to the abovementioned structure are also provided.
Claims27
A closure assembly having two ends comprising a first and second track disposed proximate each end of the assembly respectively, and a slidable and pivotable closure member, the closure member including framing sections therefor and being engaged with the first and second tracks proximate first and second pivots adjacent the pivotable end of the member, the first and second pivots being interconnected by a multiple segment shaft disposed within framing sections of said closure member, the shaft including at least two portions, the shaft providing for accurate installation, retention, removal, adjustment and alignment of the first and second pivots within the first and second tracks in a substantially parallel line with respect to one another and for pivotally supporting the closure member which may be safely and securely pivoted away from the closure assembly, whereby the first and second interconnected pivots are adapted to remain engaged with the first and second tracks while supporting the closure member both when it is pivoted away from the closure assembly and when it is slidable relative to the tracks.
A pivoting and sliding closure assembly comprising:
- i) an opening extending within a frame
- ii) the frame having two ends and having disposed therein or attached thereto proximate each end track portions extending in a substantially parallel said frame;
- iii) at least one closure member having framing portions and two ends and being slidable within said track portions and pivotable proximate at least one end thereof and latchable in the track portions proximate the other end thereof;
- iv) each of said track portions having disposed therein at least one pivot shoe adjacent the pivoting end of the closure member, each shoe being substantially compatibly shaped with the track portions and having a top and bottom, each shoe having disposed therein adjacent the pivoting end of the at least one closure member an opening extending from the top toward the bottom of the shoe wherein pivot means are disposed, said pivot means provided with said pivot shoe being interconnected by a multiple segment shaft disposed within said framing portions of said at least one closure member, the shaft including at least two portions, the shaft providing for accurate installation, retention, removal, adjustment and alignment of the first and second pivots within the track portions in a substantially parallel line for pivotally supporting the at least one closure member for safe and secure pivoting away from the closure assembly;
- v) the at least one closure member having latching means provided therewith for latching the at least one closure member in relation to the track portions to prevent the at least one closure member from pivoting upon the pivot means when the at least one closure member remains slidable with said track portions;
- vi) the at least one closure member being braced by the multiple segment shaft interconnecting the pivot means disposed with each track portions, the substantially parallel alignment of the pivot means provided by the multiple segment shaft preventing the pivot means from misaligning or disengaging from the relevant track portions when the at least one closure member is rotated to an open position or when it remains slidable within said track.
A pivoting and sliding closure assembly comprising:
- i) an opening extending within a peripheral frame said peripheral frame including a header portion, a sill portion and two vertically extending jamb portions;
- ii) the sill and header portions or the two jamb portions having disposed therein or attached thereto track portions extending in a substantially parallel direction to said peripheral frame portions;
- iii) at least one closure member having two ends and framing portions and being slidable within said track portions and pivotable proximate at least one end thereof and latchable in the track portions proximate the other end thereof;
- iv) each of the track portions having disposed therein adjacent the pivoting end of the at least one closure member, at least one pivot shoe, each pivot shoe being substantially compatibly shaped with the track portions and having a top and bottom, each pivot shoe having disposed therein adjacent the pivoting end of the at least one closure member an opening extending from the top toward the bottom of the shoe wherein pivot means are disposed, said pivot means being interconnected by a multiple segment shaft disposed within the said framing portions of said at least one closure member, the shaft including at least two portions, the shaft providing for accurate installation, retention, removal, adjustment and alignment of the pivot means in a substantially parallel line for pivotally supporting the at least one closure member for safe and secure pivoting away from the closure assembly;
- v) the at least one closure member having latching means provided therewith for latching the at least one closure member in relation to the track portions to prevent the at least one closure member from pivoting upon its pivot means when the at least one closure member remains slidable with said track portions;
- vi) the at least one closure member being braced by the multiple segment shaft which provides for accurate installation, retention, removal, adjustment and alignment of the interconnected pivot means disposed with each track portion, the substantially parallel line of the pivot means provided by the multiple segment shaft preventing the at least one closure member from misaligning or disengaging from the relevant track portion when rotated to an open position or when the at least one closure member remains slidable within said track portions.
Hardware for a closure assembly, said closure assembly having a track and a slidable and pivotable closure member, the closure member being engaged with the track proximate first and second pivots adjacent the pivotable end of the member,
- the hardware comprising the first and second pivots being interconnected by a multiple segment shaft which provides for accurate installation, retention, removal, adjustment and alignment of the first and second pivots in a substantially parallel line for pivotally supporting the closure member when the hardware is installed in said closure assembly so that it may be safely and securely pivoted away from the closure assembly, whereby the first and second interconnected pivots when the hardware is installed in said closure assembly are adapted to remain engaged with the track while supporting the closure member both when it is pivoted away from the closure assembly and when it is slidable relative to the track.
A conversion kit of components for a frame opening to convert a double-hung window or a tilt and slide window to a casement window assembly, said kit comprising framing portions for containing track portions engageable with the framing portions of the window, said track portion including a rack portion proximate at least one side thereof, a casement window sash having a carrier and interconnecting pivot assembly provided therewith and for insertion and operation with respect to the track portions of the frame, wherein when assembled said casement window fully fills the space occupied by the previously installed double-hung or tilt and slide window.
