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.
Claims34
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, 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 carriers facilitate 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 carriers facilitate rotating movement of the sash between a tilt closed position and a tilt open position with respect to the frame;
- 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.
The fenestration unit of claim 3, wherein the brake includes:
- an engagement portion movable between a retracted position with respect to the body when the brake is in the release position and an extended position with respect to 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.
A sash carrier for a fenestration unit, comprising:
- an elongated body, including:
- a first side configured for sliding movement between a sash closed position and a sash open position on a fenestration unit frame;
- and
- a second side opposite the first side;
- a sash mount to mount a sash to the second side of the body;
- and
- one or more seal members on the body to provide a weather-resistant seal between the body and the fenestration unit frame.
