Abstract

Claims (26)

1. A fenestration unit comprising:

a frame having a head, a first jamb, a second jamb, and a sill;

a sash hinged to the frame such that the sash is pivotable between an open position and a closed position; and

an operator assembly configured to transition the sash between the open and closed positions, the operator assembly including,

a rotary drive mechanism configured to rotate to impart an opening force on the sash toward the open position and a closing force on the sash toward the closed position, and

a slide mechanism operatively coupled to the drive mechanism, the slide mechanism being slidable to cause the drive mechanism to impart the opening force and the closing force, respectively, on the sash, the slide mechanism being associated with the frame and including a handle that is linearly slidable along the frame; and

a transfer mechanism operatively coupling the slide and drive mechanisms such that a first, linear input to the handle of the slide mechanism along a first axis is transferred along a second axis as a linear input force on the rotary drive mechanism.

2. The fenestration unit of claim 1 , wherein the slide mechanism is slidable along the first axis resulting in an actuation force on the rotary drive mechanism to impart the opening force and the closing force, respectively, on the sash, wherein the resultant actuation force is along the second axis which is at an angle to the first axis.

3. The fenestration unit of claim 2 , wherein the first and second axes are generally perpendicular.

4. The fenestration unit of claim 1 , wherein the first and second axes are generally perpendicular.

5. The fenestration unit of claim 1 , wherein the rotary drive mechanism includes a component that rotates about a longitudinal axis that is perpendicular to the second axis.

6. The fenestration unit of claim 5 , wherein the component that rotates about the longitudinal axis comprises a worm.

7. The fenestration unit of claim 6 , wherein the component that rotates about the longitudinal axis comprises a drive pully coupled to the worm.

8. A fenestration unit comprising:

a frame;

a sash hinged to the frame; and

an operator assembly including:

a rotary drive mechanism operable to rotate to impart an opening force on the sash;

a slide mechanism operatively coupled to the rotary drive mechanism, the slide mechanism being linearly actuatable to cause the rotary drive mechanism to impart the opening force on the sash; and

a transfer mechanism operatively coupling the slide and rotary drive mechanisms such that a first, linear input of the slide mechanism is translated in a different direction as a second, linear input on the rotary drive mechanism.

9. The fenestration unit of claim 8 , wherein the slide mechanism is slidable along a first axis corresponding to a direction of the first, linear input.

10. The fenestration unit of claim 9 , wherein the first linear, input and the second, linear input are generally perpendicular.

11. The fenestration unit of claim 10 , wherein the slide mechanism includes a linearly translatable handle that is slidable relative to the frame.

12. The fenestration unit of claim 8 , wherein the rotary drive mechanism includes a component that rotates about a longitudinal axis that is perpendicular to the direction of the second linear input.

13. The fenestration unit of claim 12 , wherein the component that rotates about the longitudinal axis comprises a worm.

14. The fenestration unit of claim 13 , wherein the component that rotates about the longitudinal axis comprises a drive pully coupled to the worm.
