Abstract

A sliding operator handle includes an actuatable brake providing at least one braking position in which the actuatable brake is configured to contact a track and restrict sliding motion of the track mount along the track and at least one sliding position in which the actuatable brake is configured to reduce contact with the track and allow sliding motion of the track mount along the track, and a handle pivotably coupled to the track mount. The handle is configured to receive a manual input force to slide the track mount in either direction along the track, and being further configured to actuate the actuatable brake in response to the manual input force. The handle includes a neutral position corresponding to the at least one braking position of the actuatable brake and actuation positions to allow sliding motion of the track mount along the track in response to manual input forces.

First claim

What is claimed is:

1. A sliding operator handle comprising:
a track mount configured to slidably mate with a track;
an actuatable brake providing at least one braking position in which the actuatable brake is configured to contact the track and restrict sliding motion of the track mount along the track and at least one sliding position in which the actuatable brake is configured to reduce contact with the track and allow sliding motion of the track mount along the track; and
a handle pivotably coupled to the track mount, the handle being configured to receive a manual input force to slide the track mount in either a first direction along the track and/or a second direction along the track, and being further configured to actuate the actuatable brake in response to the manual input force,
wherein the handle includes a neutral position corresponding to the at least one braking position of the actuatable brake,
wherein the handle includes a first actuation position corresponding to the manual input force in the first direction along the track, the first actuation position corresponding to the at least one sliding position of the actuatable brake to allow sliding motion of the track mount along the track in the first direction, and
wherein the handle includes a second actuation position corresponding to the manual input force in the second direction along the track, the second actuation position also corresponding to the at least one sliding position of the actuatable brake to allow sliding motion of the track mount along the track in the second direction.

2. The sliding operator handle of claim 1 , further comprising at least one spring that biases the handle to the neutral position.

3. The sliding operator handle of claim 1 , wherein the handle is attached to the track mount via a sliding joint.

4. The sliding operator handle of claim 3 , wherein the sliding joint includes a slider pivotably coupled to the handle.

5. The sliding operator handle of claim 1 ,
wherein the actuatable brake is attached to the track mount via a sliding joint, and
wherein the handle is pivotably connected to the actuatable brake.

6. The sliding operator handle of claim 1 ,
wherein the handle is attached to the track mount via a first sliding joint, and
wherein the actuatable brake is attached to the track mount via a second sliding joint.

7. The sliding operator handle of claim 6 , wherein the first sliding joint is about perpendicular to the second sliding joint.

8. The sliding operator handle of claim 1 , wherein the at least one sliding position of the actuatable brake includes a retracted position.

9. The sliding operator handle of claim 1 , wherein the sliding operator handle is a component of a linear input mechanism for a casement window.

10. The sliding operator handle of claim 9 , wherein the linear input mechanism comprises a gear reducer.

11. The sliding operator handle of claim 1 , further comprising at least one spring that biases the handle to the neutral position,
wherein the handle is attached to the track mount via a first sliding joint,
wherein the first sliding joint includes a slider pivotably coupled to the handle,
wherein the actuatable brake is attached to the track mount via a second sliding joint, and
wherein the handle is pivotably connected to the actuatable brake.

12. A casement window comprising:
a stationary frame;
a rotatable window sash pivotably connected to the stationary frame; and
a casement window operator, the casement window operator including:
a linear input mechanism mounted to the stationary frame;
a linear to rotary motion converter operably coupled to an output of the linear input mechanism; and
a sash arm operably coupled to an output of the linear to rotary motion converter,

wherein a distal end of the sash arm is connected to the rotatable window sash such that rotation of the sash arm drives pivoting of the rotatable window sash relative to the stationary frame,
wherein the linear input mechanism includes a track and a sliding operator handle, the sliding operator handle comprising:
a track mount slidably mated with the track;
an actuatable brake providing at least one braking position in which the actuatable brake contacts the track and restrict sliding motion of the track mount along the track and at least one sliding position in which the actuatable brake reduces contact with the track and allow sliding motion of the track mount along the track; and
a handle pivotably coupled to the track mount, the handle being configured to receive a manual input force to slide the track mount in either a first direction along the track and/or a second direction along the track, and being further configured to actuate the actuatable brake in response to the manual input force,
wherein the handle includes a neutral position corresponding to the at least one braking position of the actuatable brake,
wherein the handle includes a first actuation position corresponding to the manual input force in the first direction along the track, the first actuation position corresponding to the at least one sliding position of the actuatable brake to allow sliding motion of the track mount along the track in the first direction to open the rotatable window sash, and
wherein the handle includes a second actuation position corresponding to the manual input force in the second direction along the track, the second actuation position also corresponding to the at least one sliding position of the actuatable brake to allow sliding motion of the track mount along the track in the second direction to close the rotatable window sash.

13. The casement window of claim 12 , wherein the sliding operator handle further comprises at least one spring that biases the handle to the neutral position.

14. The casement window of claim 12 , wherein the handle is attached to the track mount via a sliding joint.

15. The casement window of claim 14 , wherein the sliding joint includes a slider pivotably coupled to the handle.

16. The casement window of claim 12 ,
wherein the actuatable brake is attached to the track mount via a sliding joint, and
wherein the handle is pivotably connected to the actuatable brake.

17. The casement window of claim 12 ,
wherein the handle is attached to the track mount via a first sliding joint, and
wherein the actuatable brake is attached to the track mount via a second sliding joint.

18. The sliding operator handle of claim 17 , wherein the first sliding joint is about perpendicular to the second sliding joint.

19. The casement window of claim 12 , wherein the at least one sliding position of the actuatable brake includes a retracted position.

20. The casement window of claim 12 ,
wherein the sliding operator handle further comprises at least one spring that biases the handle to the neutral position,
wherein the handle is attached to the track mount via a first sliding joint,
wherein the first sliding joint includes a slider pivotably coupled to the handle,
wherein the actuatable brake is attached to the track mount via a second sliding joint, and
wherein the handle is pivotably connected to the actuatable brake.

21. A method of operating a casement window, the method comprising sliding a linear input mechanism mounted to a stationary frame of the casement window,
wherein the casement window includes:
a stationary frame;
a rotatable window sash pivotably connected to the stationary frame; and
a casement window operator, the casement w
