A pump handle system includes a pump handle and a main shaft. The pump handle is operable to radially pivot from a starting position in a first pivot direction and back to the starting position in a second pivot direction opposite the first pivot direction. The main shaft is driven by the pump handle to rotate approximately a first half of a predetermined rotational distance in a first rotational direction a first time the pump handle is pivoted out from the starting position in the first pivot direction, and rotate approximately a second half of the predetermined rotational distance in the first rotational direction a first time the pump handle is pivoted back to the starting position in the second pivot direction. The main shaft rotates in a second rotational direction opposite the first rotational direction a second time the pump handle is pivoted in the two-movement push-pull motion.

A casement operator crank includes a base member, a handle, a hinged detent, and a resilient biasing member. The handle has a main body portion connects to the base member for rotation about a handle axis between an open orientation and a closed orientation. The hinged detent pivotally engages with the base member for rotation about a detent axis between a first orientation relative to the main body portion and a second orientation relative to the main body portion. The resilient biasing member acts between the hinged detent and the handle. The biasing member and hinged detent operably: a) bias the main body portion toward the open orientation about the handle axis when the main body portion is in the open orientation; and b) the main body portion toward the closed orientation about the handle axis when the main body portion is in the closed orientation.

An improved operator for a window comprising a base and a cover, the base being attached to a window sash with an aperture extending through the base, an arm having first and second ends with a first end secured to the base, the first arm having an aperture therein overlying the aperture in the base and an upper securement member extending at least partially through the aperture in the first end of the arm, the securement member having a threaded recess therein, a lower securement member screwthreadedly engaged with the upper securement member and extending through the base in an abutting relationship thereto, the cover engaging with the upper securement member to prevent rotation thereof when the lower securement member is screwthreadedly engaged therewith.

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.
