Abstract

Sash carriers mounted to the sides of a sash support the sash in a window frame for sliding movement between sliding closed and sliding open positions. Balance springs on the sash carriers counterbalance the weight of the sash during the sliding movement. The sash can be mounted to the sash carriers for tilting movement between tilt closed and tilt open positions. Brakes on the sash carriers are actuated by the sash when the sash is moved to the tilt open position, and inhibit sliding movement of the sash carriers and sash when the sash is in the tilt open position.

First claim

What is claimed is:

1 . A fenestration unit, comprising:
a frame including a first jamb and a second jamb; a sash including a first side and second side; and first and second sash carriers, each coupling one of the first side or the second side of the sash to one of the first jamb or the second jamb of the frame, each of the first and second sash carriers including:
a body, comprising:
a first side coupled for sliding movement on one of the first jamb or the second jamb, wherein the sash carrier facilitates the sliding movement of the sash between a sliding closed position and a sliding open position on the frame;
a second side opposite the first side;

a sash mount coupling one of the first side or the second side of the sash to the second side of the body, wherein the sash mount facilitates rotating movement of the sash between a tilt closed position and a tilt open position with respect to the body;
a latch member coupled to the body at a spaced-apart location with respect to the sash mount, wherein the latch member is configured to be coupled to the sash and to prevent rotation of the sash with respect to the body when the sash is in the tilt closed position, and to be released from the sash to permit the rotating movement of the sash;
one or more balance springs coupled to the body; and
a brake coupled to the body and operable by the sash between a release position facilitating the sliding movement when the sash is in the tilt closed position and a brake position inhibiting the sliding movement when the sash is in the tilt open position;
wherein each sash mount includes a pivot mount extending through the respective body to facilitate rotation of the sash between the tilt closed position and the tilt open position; wherein each brake includes:
an engagement portion movable between a retracted position within a perimeter of the body when the brake is in the release position and an extended position through an opening in the body and beyond a perimeter of the body when the brake is in the brake position;
a biasing portion to bias the engagement portion to the retracted position when the sash is in the tilt closed position; and
an actuator portion configured to be actuated by the sash and to move the engagement portion to the extended position when sash is in the tilt open position; and
wherein the sash includes an actuator arm to actuate the actuator portion of each brake, and wherein the actuator arm is coupled to the sash by a pin extending through the respective pivot mount.

2 . The fenestration unit of claim 1 , wherein each sash carrier includes one or more seal members on the body to provide a weather-resistant seal between the body and the one of the first jamb or the second jamb.

3 . The fenestration unit of claim 2 wherein the one or more seal members comprise air permeable and water-resistant members.

4 . The fenestration unit of claim 3 wherein the one or more seal members comprise felt.

5 . The fenestration unit of claim 1 , wherein the latch member includes a member that is movable with respect to the sash carrier and the sash.

6 . A fenestration unit, comprising:
a frame including a first jamb and a second jamb; a sash including a first side and second side; and first and second sash carriers, each coupling one of the first side or the second side of the sash to one of the first jamb or the second jamb of the frame, each of the first and second sash carriers including:
a body, comprising:
a first side coupled for sliding movement on one of the first jamb or the second jamb, wherein the sash carrier facilitates the sliding movement of the sash between a sliding closed position and a sliding open position on the frame;
a second side opposite the first side;

a sash mount coupling one of the first side or the second side of the sash to the second side of the body, wherein the sash mount facilitates rotating movement of the sash between a tilt closed position and a tilt open position with respect to the body;
a latch member coupled to the body at a spaced-apart location with respect to the sash mount, wherein the latch member is configured to be coupled to the sash and to prevent rotation of the sash with respect to the body when the sash is in the tilt closed position, and to be released from the sash to permit the rotating movement of the sash;
one or more balance springs coupled to the body; and
a brake coupled to the body and operable by the sash between a release position facilitating the sliding movement when the sash is in the tilt closed position and a brake position inhibiting the sliding movement when the sash is in the tilt open position;
wherein each brake includes:
an engagement portion movable between a retracted position within a perimeter of the body when the brake is in the release position and an extended position through an opening in the body and beyond a perimeter of the body when the brake is in the brake position;
a biasing portion to bias the engagement portion to the retracted position when the sash is in the tilt closed position; and
an actuator portion configured to be actuated by the sash and to move the engagement portion to the extended position when sash is in the tilt open position; and
wherein each body comprises an elongated extrusion including an elongated component mounting slot extending along a length of the body on the first side; wherein each sash carrier includes one or more brake mounting members mounted to the component mounting slot; wherein each brake is mounted to the body by the one or more brake mounting members; wherein the component mounting slot includes a T-shaped opening; and wherein the one or more brake mounting members include:
a base received in the T-shaped opening; and
a pin extending from the base.

7 . The fenestration unit of claim 6 , wherein the one or more balance springs include coil springs.

8 . The fenestration unit of claim 6 , wherein:
each sash carrier includes one or more spring mounting members mounted to the component mounting slot, and the one or more balance springs are mounted to the body by the one or more spring mounting members.

9 . A fenestration unit, comprising:
a frame including a first jamb and a second jamb; a sash including a first side and second side; and first and second sash carriers, each coupling one of the first side or the second side of the sash to one of the first jamb or the second jamb of the frame, each of the first and second sash carriers including:
a body, comprising:
a first side coupled for sliding movement on one of the first jamb or the second jamb, wherein the sash carrier facilitates the sliding movement of the sash between a sliding closed position and a sliding open position on the frame;
a second side opposite the first side;

a sash mount coupling one of the first side or the second side of the sash to the second side of the body, wherein the sash mount facilitates rotating movement of the sash between a tilt closed position and a tilt open position with respect to the body;
a latch member coupled to the body at a spaced-apart location with respect to the sash mount, wherein the latch member is configured to be coupled to the sash and to prevent rotation of the sash with respect to the body when the sash is in the tilt closed position, and to be released from the sash to permit the rotating movement of the sash;
one or more balance springs coupled to the body; and
a brake coupled to the body and operable by the sash between a release position facilitating the sliding movement when the sash is in the tilt closed position and a brake position inhibiting the sliding movement when the sash is in the tilt open position;
wherein
