Abstract
A double hung window having a tiltable sash includes a sash brake for preventing movement of the sash along the jambs while in the tilted position. The preferred sash includes respective tongues extending along the stiles that are configured for reception in corresponding channels in the jambs for slidably mounting the sash and providing a seal between the stiles and window frame. The preferred brake elements each include a base configured for fitting within a groove of a respective tongue and a brake shoe that extends into the channel. Each shoe has a length greater than the width of channel so that when the sash is tilted, the shoe engages the channel side walls to provide braking against movement while in the tilted position.
Claims15
A window comprising:
- a frame defining a window opening and presenting jambs on opposed sides of said opening, said jambs having walls including opposed side walls defining respective channels;
- and
- a window sash including opposed stiles having respective tongues extending outwardly therefrom and extending substantially along the entire lengths thereof,
- each tongue being configured for extending into a respective one of said channels for slidably mounting said sash in said opening and having structure for engaging said opposed side walls of said channels sufficiently to provide a seal between said stiles and frame,
- said sash presenting weight, said window further including balance means for balancing the weight of said sash including a pair of balance cords positioned adjacent and coupled with respective stiles,
- said tongues each including structure defining a groove therealong,
- said window further including a pair of brake elements extending outwardly from said tongues respectively and into said respective channels,
- said window being shiftable between an operating position in which said tongues are received in said respective channels and a tilted position in which said window is tilted about said brake elements with said stiles at an angle relative to said channels,
- each of said brake elements being operable for braking said sash against movement due to said balance means when in said tilted position and including:
- a base coupled with a respective tongue and configured for fitting into a respective groove and including a base extension extending along a portion of the length of said groove for preventing rotation of said brake element relative to said stile, and
- a brake show presenting a long axis generally parallel to said grooves, presenting a width of the respective channel, and presenting a length at least as great as the width of a respective channel.

A window comprising:
- a frame defining a window opening and presenting jambs on opposed sides of said opening, said jambs having walls including opposed side walls defining respective channels;
- and
- a window sash including opposed stiles having respective tongues extending outwardly therefrom and extending substantially along the entire lengths thereof,
- each tongue being configured for extending into a respective one of said channels for slidably mounting said sash in said opening and having structure for engaging said opposed side walls of said channels sufficiently to provide a seal between said stiles and frame,
- said window further including a pair of brake elements extending outwardly from said respective stiles and into said respective channels,
- said window being shiftable between an operating position in which said tongues are received in said respective channels and a tilted position in which said window is tilted about said brake elements with said stiles at an angle relative to said channels,
- each of said brake elements including a brake shoe extending into a respective one of said channels and presenting a generally rectangular configuration with rounded corners and configured so that, as said window shifts from said operating position toward said tilted position, diagonally opposed ones of said corners engage the side walls of a respective one of said channels when said angle is less than 90 degrees.

A window comprising:
- a frame defining a window opening and presenting jambs on opposed sides of said opening, said jambs having walls including opposed side walls defining respective channels;
- a window sash including opposed stiles having respective tongues extending outwardly therefrom and along the lengths thereof, said sash presenting weight
- each tongue including structure defining a groove therealong and being configured for extending into a respective channel for slidably mounting said sash in said opening and having structure for engaging said opposed side walls of said channels sufficiently to provide a seal between said stiles and frame;
- balance means for balancing the weight of said sash including a pair of balance cords positioned adjacent and coupled with respective stiles;
- and
- a pair of brake elements extending outwardly from said tongues respectively and into said respective channels,
- said window being shiftable between an operating position in which said tongues are received in said respective channels and a tilted position in which said window is tilted about said brake elements with said stiles at an angle relative to said channels,
- each of said brake elements including
- a base configured for fitting into a respective groove,
- a brake shoe extending into a respective one of said channels and presenting a generally rectangular configuration with rounded corners and configured so that, as said window shifts from said operating position toward said tiled position, diagonally opposed ones of said corners engage the side walls of a respective one of said channels when said angle is less than 30.degree. in order to brake said sash against movement due to said balance means, and
- for each of said brake elements, only one fastener extending therethrough into a respective one of said tongues through a respective one of said grooves for coupling said brake element to a respective one of said stiles, said base including a base extension extending along a portion of the length of said respective groove for preventing rotation of said brake element relative to said fastener.
