Abstract

Fenestration units that include slide mechanisms that operate the unit through linear motion. Slide mechanism designs include a handle, a slide member coupled to the handle, and a linear rail along which the slide member is slidably received such that the slide member is operable to slide in a linear motion. The slide member includes an attachment structure for operatively coupling with a drive belt to transfer linear motion through a transfer mechanism to a drive mechanism of the unit. The attachment structure is attached to the drive belt such that a position of the attachment mechanism along the length of the drive belt may be adjusted by a user.

First claim

What is claimed is:

1 . A method of adjusting a slide mechanism of a fenestration unit including a frame, a panel coupled to the frame such that the panel is movable between an open position and a closed position, a drive mechanism coupled to the frame and operable to actuate the panel between the open and closed positions, a transfer mechanism including a drive belt having a length, and a slide mechanism including a handle, a slide member coupled to the handle, and a linear rail along which the slide member is slidably received, the method including releasing a portion of the drive belt from the slide mechanism, sliding the slide mechanism along the length of the drive belt, and releasably re-attaching the slide mechanism to the drive belt.

2 . The method of claim 1 , wherein the slide mechanism includes a rocker arm biased toward a clamp member to clamp the portion of the drive belt between the rocker arm and the clamp member, and wherein releasing the portion of the drive belt from the slide mechanism includes pivoting the rocker arm to release the drive belt.

3 . The method of claim 2 , wherein engagement features of the rocker arm and/or the clamp member are mechanically engaged with the portion of the drive belt prior to releasing the drive belt.

4 . The method of claim 3 , wherein releasing the drive belt includes manually depressing an end of the rocker arm located opposite the engagement features to release the drive belt.

5 . The method of claim 2 , wherein prior to and following release of the drive belt the rocker arm and clamp member releasably pinch the drive belt between the rocker arm and the clamp member.

6 . The method of claim 2 , wherein the rocker arm is manually depressible by a user to release the drive belt to permit the slide mechanism to be adjusted along the length of the drive belt, and the method includes depressing the rocker arm.

7 . The method of claim 6 , wherein the slide member includes a biasing member to bias the rocker arm toward the clamp member, and depressing the rocker arm includes manually depressing the rocker arm against a bias force of the biasing member.

8 . The method of claim 7 , wherein releasably re-attaching the slide mechanism to the drive belt includes discontinuing the manual depression of the rocker arm.

9 . The method of claim 8 , wherein discontinuing the manual depression of the rocker am includes causing the rocker arm and clamp member to releasably pinch a portion of the drive belt.

10 . The method of claim 1 , wherein the handle projects inwardly toward a center of the fenestration unit, and sliding the slide mechanism includes grasping the handle and sliding the slide member on the linear rail.

11 . The method of claim 1 , wherein the handle projects interiorly away from an interior side of the fenestration unit, and sliding the slide mechanism includes grasping the handle and sliding the slide member on the linear rail.

12 . The method of claim 1 , wherein the panel is hinged to the frame such that the panel is pivotable between the open position and the closed position.

13 . The method of claim 1 , wherein the fenestration unit is a casement window.
