Abstract
A projection window operator providing horizontal displacement of a window relative to a vertical plane of the frame of the window. With at least one projection window operator installed on each of opposing sides of the window, the window can be actuated between a first closed position and second open position in which a trickle ventilation is provided around the window. The projection window operators installed on the window can be interconnected for simultaneous actuation, or actuated individually, providing selective ventilation on either side.
Claims8
A projection window operator comprising:
- a base adapted to be fixedly coupled to a window frame, the base defining a channel therein;
- a window sash interface portion adapted to be fixedly coupled to a window sash movably attached to the window frame;
- a cam engaged with the channel of the base, the cam selectively slidably positionable in the channel between a first position and a second position relative to the base;
- and
- an arm operably coupling the cam to the window sash interface portion, the window sash interface portion being positioned by the arm in a first retracted position proximate the channel when the cam is positioned in the first position and the window sash interface portion being positioned by the arm in a second extended position spaced-apart from the channel when the cam is positioned in the second position, so that when the base is coupled to the window frame and the window sash interface portion is coupled to the window sash, movement of the cam from the first to the second position projects the window sash outward from the window frame, wherein the cam includes a body portion with a generally s-shaped cam slot defined in the body portion, the cam slot having a pair of opposing ends, wherein the arm includes a cam follower portion, and wherein the cam follower portion is slidably disposed in the s-shaped cam slot of the cam.

A projection window and operator system comprising:
- a window including a window frame and a window sash movably attached to the window frame;
- and
- an operator operably coupling the window frame the window sash, the operator comprising:
- a base fixedly coupled to the window frame, the base defining a channel therein;
- a window sash interface portion fixedly coupled to the window sash;
- a cam engaged in with the channel of the base, the cam selectively slidably positionable in the channel between a first position and a second position relative to the base, wherein the cam includes a body portion with a generally s-shaped cam slot defined in the body portion;
- and an arm operably coupling the cam to the window sash interface portion, wherein the arm includes a cam follower portion, and wherein the cam follower portion is slidably disposed in the s-shaped cam slot of the cam, the window sash interface portion being positioned by the arm in a first retracted position proximate the channel when the cam is positioned in the first position and the window sash interface portion being positioned by the arm in a second extended position spaced-apart from the channel when the cam is positioned in the second position, so that movement of the cam from the first position to the second position projects the window sash outward from the window frame.

A method of operating a window having a window frame and a window sash movably attached to the window frame comprising the steps of:
- a) providing an operator comprising:
- a base defining a channel therein;
- a window sash interface portion;
- a cam engaged with the channel of the base, the cam selectively slidably positionable in the channel between a first position and a second position relative to the base, the cam including a body portion with a generally s-shaped cam slot defined in the body portion;
- and
- an arm operably coupling the cam to the window sash interface portion, the arm including a cam follower portion, wherein the cam follower portion is slidably disposed in the s-shaped cam slot of the cam, the window sash interface portion being positioned by the arm in a first retracted position proximate the channel when the cam is positioned in the first position and the window sash interface portion being positioned by the arm in a second extended position spaced-apart from the channel when the cam is positioned in the second position;
- b) attaching the base to the window frame;
- c) attaching the window sash interface portion to the window sash;
- and
- d) sliding the cam from the first position to the second position to project the window sash outward from the window frame, thereby opening the window.
