Window opening limit devices and method of use
A method of operating a window having a sash and a window opening limit device includes moving the sash from a closed position to a limited position. When in the limited position, the window opening limit device is in a projected position, and the sash is engaged with the window opening limit device. Moving the window opening limit device to a retracted position disengages the sash and the window opening limit device. The sash may then be moved from the limited position to an open range. When the sash is returned to the closed position, the window opening limit device automatically returns to the projected position, and the sash is disengaged with the window opening limit device.
1. A window opening limit device comprising:
a bezel comprising a bezel face and an opposite rear face;
a slider slidably engaged with the rear face of the bezel;
an opening defined within the bezel;
a button movably engaged with the slider, wherein the slider and the button are together slidable between a first position and a second position along the bezel, and wherein the button is pivotally positionable in a retracted positioned with the button disposed within the slider and a projected position with at least a portion of the button projecting from the slider and extending through the opening; and
a biasing element that pivotally biases the button towards the projected position.
2. The window opening limit device of claim 1 , wherein the button is connected to the slider with an axle.
3. The window opening limit device of claim 2 , wherein the axle is disposed on an opposite end of the button from the biasing element.
4. The window opening limit device of claim 1 , wherein the slider comprises an at least partially enclosed housing that houses the button.
5. The window opening limit device of claim 1 , wherein the rear face of the bezel comprises a recess and the slider comprises a face, and wherein the recess is sized and shaped to at least partially receive the face and form a sliding track for the slider to engage with the bezel.
6. The window opening limit device of claim 1 , wherein the bezel comprises at least one projection extending from the rear face of the bezel.
7. The window opening limit device of claim 6 , wherein the slider includes at least one stop, and wherein when the at least one stop engages with the at least one projection, the slider is positioned at the first position or the second position along the bezel.
8. The window opening limit device of claim 6 , wherein the slider comprises a housing that supports the button, and wherein the at least one stop is formed by a portion of the housing.
9. The window opening limit device of claim 6 , wherein the slider comprises a housing that supports the button, and wherein the at least one stop is an extension element extending from the housing.
10. The window opening limit device of claim 1 , further comprising a return spring for biasing the slider toward the first portion.
11. The window opening limit device of claim 1 , wherein when the button is in the retracted position, the button is positioned substantially behind a plane defined by the bezel face, and wherein when the button is in the projected position, at least a portion of the button projects beyond the plane defined by the bezel face.
12. The window opening limit device of claim 1 , further comprising at least one locking element for securing the window opening limit device to a window sash.
13. A window system comprising:
a first sash;
a second sash, wherein the first sash is slidable relative to the second sash; and
a window opening limit device coupled to the second sash, wherein the window opening limit device comprises:
a bezel;
a slider slidably engaged with the bezel;
a button pivotably engaged with the slider, wherein the slider and the button are together slidable between a first position and a second position along the bezel, and wherein the button is positionable in a retracted position disposed within the slider and a projected position projecting from the slider; and
a biasing element for biasing the button pivotably toward the projected position.
14. The window system of claim 13 , wherein the first sash is slidably positionable in a closed range, a contacted range, a limited position, and an open range.
15. The window system of claim 14 , wherein when the first sash is in the closed range, the button is in the projected position and the first sash is not engaged with the button.
16. The window system of claim 14 , wherein when the first sash is in the contacted range, the button is in the projected position and the first sash is engaged with the button.
17. The window system of claim 14 , wherein when the first sash is in the limited position, the button is in the projected position and the first sash is engaged with the button.
18. The window system of claim 14 , wherein when the first sash is in the open range, the button is in the retracted position and the first sash is not engaged with the button.
19. The window system of claim 14 , wherein the slider is in the first position when the first sash is in each of the closed range and the open range, and wherein the slider is in the second position when the first sash is in the limited position.
