Screen frame having spring spline

Abstract

A screen frame includes a beam having a groove, a screen material to be attached onto the beam, and a spline member having two spring blades extended outwardly from a base panel and inclined relative to the base panel and having free end portions extended away from each other, for engaging into the groove of the beam, and for forcing and anchoring the screen material onto the beam. The spring blades each includes an anchor segment having the outer inclined surface for easily forcing the screen material into the groove of the beam, and one or more anchor portions to engage with projections of the beam, and to further anchor and retain the spring blades within the groove of the beam.

1 . A screen frame comprising: 
 a beam including a groove formed therein,    a screen material to be attached onto said beam, and    a spline member including base panel, and two spring blades extended outwardly therefrom and inclined relative to said base panel and having free end portions extended away from each other, for engaging into said groove of said beam, and for forcing and anchoring said screen material onto said beam.    
   
   
       2 . The screen frame as claimed in  claim 1 , wherein said spring blades each includes an outer inclined surface formed in said free end portion thereof, for engaging with said beam, and for allowing said spring blades to easily force and engage said screen material into said groove of said beam.  
   
   
       3 . The screen frame as claimed in  claim 2 , wherein said spring blades each includes an anchor segment extended inwardly from said free end portion thereof, having said outer inclined surface formed on said anchor segment.  
   
   
       4 . The screen frame as claimed in  claim 1 , wherein said spring blades include at least one anchor portion formed on said free end portion thereof, and said beam includes at least one projection extended into said groove of said beam, to engage with said at least one anchor portion of said spring blades, and to anchor and retain said spring blades within said groove of said beam.  
   
   
       5 . The screen frame as claimed in  claim 1 , wherein said groove of said beam includes a wider inner portion and a narrower outer portion, to form two inclined surfaces therein, and to engage with said outwardly inclined spring blades.  
   
   
       6 . The screen frame as claimed in  claim 5 , wherein said inclined surfaces of said beam are parallel to said outwardly inclined spring blades.  
   
   
       7 . The screen frame as claimed in  claim 1 , wherein said beam includes an outer covering attached onto an outer peripheral portion thereof, to protect said beam.  
   
   
       8 . The screen frame as claimed in  claim 1 , wherein said beam includes an edge portion having a reduced thickness, to form a space therein, and to receive said base panel of said spline member.
