Apparatus for Making Window Screen Sash

Abstract

A screen frame is made by joining four or more straight frame pieces and four corner pieces to one another in a square or rectangular shape. Each straight frame piece and each corner piece have an outboard part and an inboard part with a channel formed in it. The outboard part of each straight frame piece is hollow and has an aperture formed in its opposite ends. Each corner piece includes an apertured protuberance at opposite ends of its outboard part. An alternative embodiment adds a plurality of extension members that may be coupled to the straight frame members. Each extension member has an apertured protuberance formed in a first end of its hollow outboard part and an aperture formed in a second end of its hollow outboard part.

1 . An apparatus for making a frame for a screen, comprising: 
 a plurality of straight frame members;    each straight frame member of said plurality of straight frame members having an outboard part of hollow construction formed integrally with an inboard part having a channel formed therein;    each straight frame member having a first aperture formed in a first end of said outboard part and a second aperture formed in a second end of said outboard part.    
   
   
       2 . The apparatus of  claim 1 , further comprising: 
 a plurality of corner members;    each corner member of said plurality of corner members having an “L”-shaped outboard part formed integrally with an “L”-shaped inboard part having a channel formed therein;    a first apertured protuberance formed in a first end of the outboard part of each corner member; and    a second apertured protuberance formed in a second end of the outboard part of each corner member.    
   
   
       3 . The apparatus of  claim 2 , further comprising: 
 a plurality of pins adapted to be positioned in respective apertures formed in said straight frame members and said corner members when said straight frame members and corner members are cooperatively connected to one another to form said frame for a screen;    whereby said frame is formed by interconnecting a plurality of said straight frame members and a plurality of said corners members into a square or rectangular configuration by inserting respective protuberances of said corner members into respective hollow interiors of said outboard parts of said straight frame members so that the respective outboard and inboard parts of said straight frame members and said corner members are in cooperative alignment with one another, so that respective apertures formed in said protuberances of said outboard parts of said corner members are in alignment with respective apertures formed in said outboard parts of said straight frame members, and so that said respective apertures are maintained in alignment with one another by respective pins of said plurality of pins.    
   
   
       4 . The frame of  claim 1 , further comprising: 
 a plurality of extension members;    each extension member of said plurality of extension members having an outboard part of hollow construction integrally formed with an inboard part having a channel formed therein;    each extension member having an apertured protuberance formed in a first end of its outboard part;    each extension member including an aperture formed in a second end of its outboard part;    a plurality of pins adapted to be positioned in respective apertures formed in said straight frame members and said extension members when said straight frame members and extension members are cooperatively connected to one another to form said frame for a screen;    whereby an extension member is connected to a straight frame member by inserting said apertured protuberance formed in said first end of said extension member into a hollow interior of said outboard part of said straight frame member so that said aperture formed in said protuberance of said extension member is aligned with an aperture formed in said outboard part of said straight frame member;    whereby said aperture formed in said protuberance of said extension member and said aperture formed in said outboard part of said straight frame member are maintained in said alignment with a pin of said plurality of pins.
