Abstract
Abstract A metallic picture frame construction including corner frame elements which connect rectilinear segments in an attractive manner in which the interconnecting screws are concealed from view. The corner elements surround the ends of the rectilinear segments, and they are maintained in engagement solely by compressive forces exerted by the screws making unnecessary the drilling of holes in the rectilinear members. The invention has application to wood rectilinear segments as well, using wood screws which penetrate the corner elements and the rectilinear segments.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
Improved picture frame construction comprising: a plurality of rectilinear side segments defining the periphery of a rectangular frame, and a plurality of corner elements interconnecting said side segments at the ends thereof; said side segments being of a given cross-sectional configuration, and defining a longitudinal recess for the accommodation of a side surface of a displayed picture; said side surfaces of said longitudinal segments defining a substantially continuous surface bordering said recess; said corner elements having a cross sectional configuration corresponding to that of said given cross-sectional configuration of said side segments, and slidably engaging the outer surfaces of said side elements while leaving said recess exposed; and threaded means penetrating said corner elements and engaging said side segments in areas spaced from said recess to maintain said segments and said corner elements in mutually interconnected condition.
Claim 2
Dependent Claim
137 words
Improved picture frame construction comprising: a plurality of rectilinear side segments defining the periphery of a rectangular frame, and a plurality of corner elements interconnecting said side segments at the ends thereof; said side segments being of a given cross-sectional configuration, and defining a longitudinal recess for the accommodation of a side surface of a displayed picture; said side surfaces of said longitudinal segments defining a substantially continuous surface bordering said recess; said corner elements having a cross sectional configuration corresponding to that of said given cross-sectional configuration of said side segments, and slidably engaging the outer surfaces of said side elements while leaving said recess exposed; and threaded means penetrating said corner elements and engaging said side segments in areas spaced from said recess to maintain said segments and said corner elements in mutually interconnected condition.
Claim 3
Dependent Claim
32 words
Picture frame construction in accordance with claim 1, characterized in said side segments being of wood, and said threaded means comprising wood screws penetrating both said corner elements and said side segments.
Claim 4
Dependent Claim
155 words
Improved picture frame construction comprising: a plurality of rectilinear side segments defining the periphery of a rectangular frame, and a plurality of corner elements interconnecting said side segments at the ends thereof; said side segments being of a given cross-sectional configuration, and defining a first longitudinal recess for the accommodation of a side surface of a displayed picture, and a second longitudinal recess for the reception of means for interconnecting said side segments at the ends thereof, said side segments defining a substantially continuous outer surface bordering said first and second recesses; said corner elements having a cross-sectional configuration corresponding to that of said given cross-sectional configuration of said side segments, and slidably engaging the outwardly exposed surfaces of said side segments, including those defining said second recess, while leaving exposed said first recess; and set screw means penetrating said corner elements and bearing upon said side segments at a surface of said second recess.
Claim 5
Dependent Claim
155 words
