In the embodiment shown in Fig. 6, the springs 8 are anchored to the inner frames I as at 8a to prevent shifting of the springs 8 during use.
In use, the outer frame of the unit is manually contracted, and the unit placed in the window sill. The outer frame is then released so that it expands and fills the window sill snugly, forming an insect-proof seal which, in addition, holds the unit firmly in place.
I do not limit my invention to the exact forms shown in the drawings, for obviously changes may be made within the scope of the claims.
1. A jointed closure frame comprising frame members having mitered ends which abut at the joints, each member having an angular cross section and including side portions defining a longitudinal channel, and the side portions of one member at each joint being offset outwardly from the miter to provide a connecting male extension receivable longitudinally in the adjacent end of the other member.
2. A jointed closure frame comprising hollow jointed frame members, each having mitered ends which abut at the joints; each frame member having an angular male section at one end consisting of parallel portions adapted to fit within the end of the adjacent frame member; each male section having parallel portions offset inwardly from the contiguous portions of the adjacent frame member into which itfits; and one of said parallel portions of each male section having an angular lip at its outer end engaged with the outer end of the other parallel portion thereof.
3. In a closure as set forth in claim 2, the 01!- set of the outer parallel portion of each male section forming a ridge to insure tight wedging action with the outer wall of the adjacent frame member when the frame members are assembled.
4. A jointed closure frame comprising hollow jointed frame members, each having mitered ends which abut at the joints; each frame member having an angular male section at one end consisting of parallel portions adapted to fit within the end of the adjacent frame member; each male section having parallel portions offset inwardly from the contiguous portions of the adjacent frame member into which it fits; the side walls connecting the parallel portions of the male sections being cut away; and one of said parallel portions of each male section having an angular lip at its outer end secured to the outer end of the other parallel portion thereof.
5. In a closure as set forth in claim 4, the offset of the outer parallel portion of each male section forming a ridge to insure tight wedging action with the outer wall of the adjacent frame member when the frame members are assembled.
