Removable window sash system with integrated spring biased retainer
View Patent ↗A spacer that attaches to a window sash in order to create an improved window construction. The window construction has a window frame with side tracks. A window sash is set within the side tracks of the window frame. Gap spaces exist between the window sash and the side tracks. To prevent cocking, spacers are provided. The spacers attached to the sides of the window sash inside the tracks where the spacer is not visible. Each spacer has a base, a spring arm that extends from the base, and a contact head that is supported by the spring arm. The base is mounted to the window sash within a gap space. The spring arm extends into the gap space and biases the contact head toward the side track. The contact head also presents a physical barrier to lateral movement. This inhibits the sash from cocking within the window frame.
1. A window construction, comprising:
a window frame having side tracks;
a window sash having side framing elements that are set within said side tracks of said window frame, wherein each of said side framing elements have two side walls that define a groove along each of said side framing elements, wherein each of said side walls extends along a plane and terminates along a wall edge, and wherein a gap exists between each said wall edge and said window frame;
a first spacer having a first base, a first spring arm that extends from said first base, and a first contact head supported by said first spring arm, wherein said first base is mounted to said window sash within said groove and said first spring arm biases said first contact head into a position that extends within one of said planes and that overlaps said wall edge of one of said side walls in said gap between said wall edge and said window frame, therein inhibiting said window sash from cocking within said window frame.
2. The window construction according to claim 1 , wherein said first base is mounted to said window sash with a mechanical fastener that physically connects said first base to said window sash.
3. The window construction according to claim 1 , further including a projection that extends outwardly from said first contact head.
4. The window construction according to claim 1 , further including a second spacer having a second base, a second spring arm that extends from said second base, and a second contact head supported by said second spring arm, wherein said second base is mounted to said window sash and said second spring arm biases said second contact head into a second position that overlaps said wall edge of one of said side walls in between said wall edge and said window frame, therein inhibiting said window sash from cocking within said window frame.
5. The window construction according to claim 4 , wherein said second base is mounted to said window sash with a screw that physically connects said second base to said window sash.
6. The window construction according to claim 4 , further including a second projection that extends outwardly from said second contact head.
7. A window sash, comprising;
a sash framework having a first side sash element, wherein a first groove is formed between two side walls that extend along said first side sash element, wherein each of said side walls extends along a plane and terminates with a wall edge;
at least one pane of glass supported by said sash framework; and
a first spacer having a first base, a first spring arm that extends from said first base, and a first contact head supported by said first spring arm, wherein said first base is mounted to said first side sash element within said first groove and said first spring arm extends away from said sash framework biasing said first contact head into a position that extends within one of said planes and that overlaps said wall edge of one of said side walls.
8. The window sash according to claim 7 , further including a second spacer having a second base, a second spring arm that extends from said second base, and a second contact head supported by said second spring arm.
