Tilt slider

A pivoting and sliding window assembly comprising:

• (i) an opening extending between 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 the extensions of said peripheral frame portions
• (ii)(a) at least one window sash slidable within said track portions and pivotable at, at least one end thereof and latchable at the other end thereof (iii) each track portions having disposed therein at least two pivot shoes being interconnect by interconnecting means, each pivot shoe including a carrier portion having a top and bottom, the carrier further having interconnecting portions therein to interconnect with the interconnecting means the carrier portion having disposed therein an opening extending from top to bottom wherein camming means are disposed, said camming means being moveable to cause locking means disposed with said pivot shoe to engage and lock the pivot shoe from sliding movement in the track portions
• (iv) some of the camming means of some of the pivot shoes having engagement means therein for engagement with pivot means of the at least one window sash to allow the at least one window sash to rotate when free to do so and upon rotation thereof to cause the camming means to rotate thus locking the locking means of the pivot shoe
• (v) some of the camming means of some of pivot shoes having latching means engaged therewith for latching the window sash having latch engaging means thereon to prevent the at least one window sash from pivoting upon its pivot means when the closure member remains slidable with said track and which when disengaged locks the pivot shoe in position with respect to the track by engaging the locking means thereof
• (vi) the at least one window sash being braced from sagging by the interconnecting means interconnecting the pivot shoes disposed in each track, the interconnecting means further preventing the pivot means from disengaging from the relevant pivot shoe when the window sash is rotated to an open position.

For use in a pivoting and sliding closure assembly, a closure member slidable within a guiding channel having outwardly extending flanges and pivotable therefrom, the closure member having a substantially rectangular frame having a top and bottom, and having engaged at its top and bottom at one end pivot pins for engaging a first and second pivot shoe, and having disposed at the other end thereof proximate its top and bottom means for engaging a third and fourth pivot shoe,

• said pivot shoes slidable in said guiding channel and comprising a generally rectangular body having a top and bottom and having disposed proximate the bottom thereof at least one roller or wheel, said pivot shoes having disposed proximate the top of one end thereof fastening means to fasten the first and third, and the second and fourth pivot shoes together by connecting means extending therebetween, each pivot shoe having a slot disposed at the end thereof remote the fastening means, said slot including an opening therein for a cam member, said slot and opening extending from proximate the top to proximate the bottom of said pivot shoe, said cam member being substantially cylindrical having a central axis and having camming means thereupon or upon the perimeter of the opening of said slot wherein an opening extends into said cam for insertion of the pivot pins connected to the closure member for the first and second pivot shoe and a handle member for the third and fourth pivot shoe, said handle member having engagement means thereupon for engagement with the means for engaging the third and fourth pivot shoe of the closure member, the rectangular body having two legs, one on each side of the slot, having a clamping surface upon the surface of the rectangular body adjacent the outwardly extending flanges of the guide channel;
• whereby when the handle member of the third and fourth pivot shoes are rotated the pivot pin and the cam member rotate, and the two legs of the rectangular body move laterally away from the cam member urged by the camming means, the clamping surface thus engages the outwardly extending flanges of the guide channel thus locking the third and fourth pivot shoes in position in relation to said first and second pivot shoes, however rotation of the handle member disengages the means for engaging the third and fourth pivot shoes and the closure member, allowing the pivoting of the closure member upon the first and second pivot shoes upon the pivot pins away from the guide channel, the closure member when pivoted causes the cam member of the first and second pivot shoe to rotate wherein the first and second pivot shoes are locked in position in the guide channel in identical manner to the third and fourth pivot shoe further prevented from movement under the weight of the closure member by the third and fourth pivot shoes locked and interconnected to the first and second pivot shoes.
