Removable window vent stop
View Patent ↗A window vent stop is disclosed having a housing with a peripheral flange defining an opening, and a body depending from the peripheral flange. A stop block is mounted within the body of the housing for movement between an open position wherein a portion of the stop block protrudes above the peripheral flange and a closed position. A spring leg is located on a bottom end of the housing and flexes toward the housing when under compression, providing compressive force along a line parallel to a longitudinal axis of the housing when the window vent stop is inserted into an opening in a window sash. By applying force to further compress the spring leg, the vent stop can be readily removed from the window sash without damage.
1. A window vent stop comprising a housing including a peripheral flange defining an opening, and a body depending from the peripheral flange; a stop block mounted within the body of the housing for movement between an open position wherein a portion of the stop block protrudes above the peripheral flange and a closed position; a flexible spring leg on a first end of the housing defining a projection located proximate a distal end of the spring leg and spaced from the distal end by a pre-determined distance, the spring leg configured to provide compressive force along a line parallel to a longitudinal axis of the housing when the window vent stop is inserted into an opening in a window sash, and is configured to provide flexion along the line parallel to the longitudinal axis of the housing, but in the opposite direction relative to when the window vent stop is inserted into the opening in the window, thereby facilitating the removal of the window vent stop; and a second end opposite the first end of the housing, the second end defining an angular orientation and extending inwardly toward a back of the housing, forming a ramp surface with a notch adjacent the peripheral flange, the notch spaced from the ramp surface by a pre-determined distance.
2. The window vent stop of claim 1 , wherein the peripheral flange comprises straight lateral sides and semi-circular ends.
3. The window vent stop of claim 1 , wherein the stop block has a top surface with a series of ridges.
4. The window vent stop of claim 1 , wherein the spring leg comprises an arched section and a straight section.
5. The window vent stop of claim 1 , wherein the spring leg comprises an arched section and a straight section, wherein the arched section is proximate the housing.
6. The window vent stop of claim 1 , wherein the spring leg comprises an arched section and a straight section, wherein the projection is affixed in perpendicular orientation to the straight section.
7. The window vent stop of claim 1 , wherein the spring leg comprises an arched section and a straight section, wherein the arched section is proximate the housing and wherein the projection is affixed in perpendicular orientation to the straight section.
8. The window vent stop of claim 1 , wherein the spring leg is configured to be partially compressed when the vent stop is installed in a window sash.
9. The window vent stop of claim 1 , wherein the spring leg further comprises an arched section and a straight section, the straight section attached via the arched section at a back of the housing and projecting upward and outwardly toward the peripheral flange, the straight section terminating short of the peripheral flange to form a gap between the spring leg and the peripheral flange.
10. The window vent stop of claim 1 , wherein the spring leg further comprises an arched section and a straight section, the straight section attached via the arched section at a back of the housing and projecting upward and outwardly toward the peripheral flange, the straight section terminating short of the peripheral flange to form a gap between the spring leg and the peripheral flange; and wherein the spring leg on the first end comprises an arched section and a straight section, wherein the arched section is proximate the housing and wherein the projection is affixed in perpendicular orientation to the straight section.
11. A window vent stop consisting of a housing including a peripheral flange defining an opening, and a body depending from the peripheral flange; a stop block mounted within the body of the housing for movement between an open position wherein a portion of the stop block protrudes above the peripheral flange and a closed position; a flexible spring leg on a first end of the housing defining a projection oriented perpendicular to a straight spring leg portion and located proximate a distal end of the spring leg and spaced from the distal end by a pre-determined distance, the spring leg configured to provide compressive force along a line parallel to a longitudinal axis of the housing when the window vent stop is inserted into an opening in a window sash, and is configured to provide flexion along the line parallel to the longitudinal axis of the housing, but in the opposite direction relative to when the window vent stop is inserted into the opening in the window, thereby facilitating the removal of the window vent stop; and a second end opposite the first end of the housing, the second end defining an angular orientation and extending inwardly toward a back of the housing, forming a ramp surface with a notch adjacent the peripheral flange, the notch spaced from the ramp surface by a pre-determined distance.
