Abstract

A fenestration assembly includes a sash, a frame surrounding the sash, and at least one screen assembly mounted in at least one of: the top portion and the bottom portion. The frame includes a top portion, a bottom portion, and two jambs forming first slots extending lengthwise along at least a portion of the jamb. The first slots each include a screen edge retention feature. The screen assembly includes a roller assembly substantially hidden from view, a screen material attached to the roller assembly, and a plurality of raised features. Edges of the screen material extend into the first slots. The raised features are attached to each of the edges of the screen material. The raised features are configured to engage the screen edge retention features and retain each of the edges of the screen material at least partially within the first slot of each of the two jambs.

First claim

We claim:

1. A fenestration assembly comprising:
a sash;
a frame surrounding the sash, the frame including:
a head; and
a sill; and

two jambs connecting the head to the sill, the sash slideably engaged with the two jambs, each of the two jambs including:
an interior facing surface perpendicular to a plane of the sash;
a first slot in the interior facing surface and extending longitudinally from the sill and toward the head, the first slot defining first and second opposing inner faces parallel to the plane of the sash, the first slot including:
a chamfered portion defined at an intersection of the interior facing surface of the jamb and the first inner face of the first slot at an end of the first slot adjacent to the sill; and
a transition portion between the chamfered portion and a remainder of the first slot; and

a rethreading slot through the jamb and into communication with the first slot, and disposed at an end of the jamb adjacent to the sill; and

a screen assembly mounted in the sill, the screen assembly including:
a roller assembly substantially hidden from view; and
a screen material attached to the roller assembly, a leading end of the screen material coupled to the sash, the screen assembly configured to wind the screen material around the roller assembly and to permit the screen material to unwind from the roller assembly, edges of the screen material extending into the first slot of each of the two jambs; and

wherein the rethreading slot facilitates automatic rethreading of the edges of the screen material into the first slot of each of the two jambs when the leading end of the screen material moves through the chamfered portion and the transition portion of the first slot during the winding of the screen material if the edges of the screen material, when not wound on the roller assembly, have been forced out of the first slot.

2. The fenestration assembly of claim 1 , wherein a height of each rethreading slot is approximately 1.5 inches or less.

3. The fenestration assembly of claim 1 , wherein each transition portion includes a surface curvature that blends the chamfered portion with the remainder of the first slot.

4. The fenestration assembly of claim 1 , wherein the frame further includes a screen edge retention feature disposed within, and extending along at least a portion of, the remainder of each first slot; and the screen assembly further includes a plurality of raised features, at least one of the plurality of raised features attached to each of the edges of the screen material and extending along a portion of the edges of the screen material, the raised features configured to engage the screen edge retention features and retain each of the edges of the screen material at least partially within the first slot of each of the two jambs.

5. The fenestration assembly of claim 4 , wherein each of the two jambs further includes a low friction material strip disposed within, and extending along, each of the first slots opposite each screen edge retention feature, the low friction material strip including a resilient portion projecting toward the screen edge retention feature, the resilient portion not extending beyond an end of the screen edge retention feature nearest the sill.

6. The fenestration assembly of claim 1 , wherein the leading end of the screen material is releasably coupled to the sash.

7. The fenestration assembly of claim 6 , further comprising a control bar on the leading end of the screen material, wherein the control bar is releasably coupled to the sash.

8. The fenestration assembly of claim 7 , further comprising magnets to releasably couple the control bar to the sash.
