Abstract

Abstract A decorative window grill construction employing a plurality of interconnected, elongated grill bars of flattened construction to insert within the insulating space of an insulated window assembly and including connecting pins affixed at the free ends of the grill bars for insertion into undersized holes provided in the periphery of the insulated glass construction. The grill bars insert within axially aligned bores and distort portions of the internal grill bar construction. Grill bars forming diamond shaped configurations and having axially aligned central bores abut in angular relation by means of undersized bent pins which insert within the bores and restrict therein at the bent portions.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 301 words
In a joint for connecting angular abutting members of a decorative grill wherein the grill bars are provided with small, axially aligned bores, the combination of A. a pair of elongated grill bars each having a joined end and a free end, 1. the said bars abutting at the said joined ends thereof in angular relation, 2. each said axially aligned bore extending through the joined end, a. each bore being fabricated with a cross sectional dimension of approximately one-sixteenth of an inch, b. the said bores communicating at the joined ends thereof to form an end positioned recess, the recess being accessible from outside of the joint; and B. a pin, said pin being bent intermediate its length to form an apex and a pair of bore insertable legs angularly extending from the apex, 1. said pin being half round in cross-sectional configuration, 2. said pin having a cross-sectional diameter less than the dimension of each bore, 3. each said bore insertable leg being bent only once intermediate its length to form a bore restrictive bend, 4. the said apex of the pin being positioned within the recess and being exposed from outside of the joint, 5. each said bore insertable leg inserting within the bore of an abutting grill bar to secure the grill bars in angular relation, a. each said bore restrictive bend binding against a portion of the periphery of its associated bore to restrict relative movement between the pin and the grill bars, 6. said pin being fabricated of steel and having a natural spring bias, a. the spring bias of the pin material acting at the said bore restricing bends to develop sufficient frictional forces, between the pin and the bar construction which defines the bores to prevent the joint from being easily pulled apart.
Claim 2
Dependent Claim 301 words
In a joint for connecting angular abutting members of a decorative grill wherein the grill bars are provided with small, axially aligned bores, the combination of A. a pair of elongated grill bars each having a joined end and a free end, 1. the said bars abutting at the said joined ends thereof in angular relation, 2. each said axially aligned bore extending through the joined end, a. each bore being fabricated with a cross sectional dimension of approximately one-sixteenth of an inch, b. the said bores communicating at the joined ends thereof to form an end positioned recess, the recess being accessible from outside of the joint; and B. a pin, said pin being bent intermediate its length to form an apex and a pair of bore insertable legs angularly extending from the apex, 1. said pin being half round in cross-sectional configuration, 2. said pin having a cross-sectional diameter less than the dimension of each bore, 3. each said bore insertable leg being bent only once intermediate its length to form a bore restrictive bend, 4. the said apex of the pin being positioned within the recess and being exposed from outside of the joint, 5. each said bore insertable leg inserting within the bore of an abutting grill bar to secure the grill bars in angular relation, a. each said bore restrictive bend binding against a portion of the periphery of its associated bore to restrict relative movement between the pin and the grill bars, 6. said pin being fabricated of steel and having a natural spring bias, a. the spring bias of the pin material acting at the said bore restricing bends to develop sufficient frictional forces, between the pin and the bar construction which defines the bores to prevent the joint from being easily pulled apart.
Claim 3
Dependent Claim 78 words
each said axially aligned bore extending through the joined end, a. each bore being fabricated with a cross sectional dimension of approximately one-sixteenth of an inch, b. the said bores communicating at the joined ends thereof to form an end positioned recess, the recess being accessible from outside of the joint; and B. a pin, said pin being bent intermediate its length to form an apex and a pair of bore insertable legs angularly extending from the apex,
Claim 4
Dependent Claim 78 words
each said axially aligned bore extending through the joined end, a. each bore being fabricated with a cross sectional dimension of approximately one-sixteenth of an inch, b. the said bores communicating at the joined ends thereof to form an end positioned recess, the recess being accessible from outside of the joint; and B. a pin, said pin being bent intermediate its length to form an apex and a pair of bore insertable legs angularly extending from the apex,
Claim 5
Dependent Claim 13 words
said pin having a cross-sectional diameter less than the dimension of each bore,
Claim 6
Dependent Claim 13 words
said pin having a cross-sectional diameter less than the dimension of each bore,
Claim 7
Dependent Claim 18 words
each said bore insertable leg being bent only once intermediate its length to form a bore restrictive bend,
Claim 8
Dependent Claim 18 words
each said bore insertable leg being bent only once intermediate its length to form a bore restrictive bend,
Claim 9
Dependent Claim 19 words
the said apex of the pin being positioned within the recess and being exposed from outside of the joint,
Claim 10
Dependent Claim 19 words
the said apex of the pin being positioned within the recess and being exposed from outside of the joint,
Claim 11
Dependent Claim 50 words
each said bore insertable leg inserting within the bore of an abutting grill bar to secure the grill bars in angular relation, a. each said bore restrictive bend binding against a portion of the periphery of its associated bore to restrict relative movement between the pin and the grill bars,
Claim 12
Dependent Claim 50 words
each said bore insertable leg inserting within the bore of an abutting grill bar to secure the grill bars in angular relation, a. each said bore restrictive bend binding against a portion of the periphery of its associated bore to restrict relative movement between the pin and the grill bars,
Claim 13
Dependent Claim 52 words
said pin being fabricated of steel and having a natural spring bias, a. the spring bias of the pin material acting at the said bore restricing bends to develop sufficient frictional forces, between the pin and the bar construction which defines the bores to prevent the joint from being easily pulled apart.
Claim 14
Dependent Claim 52 words
said pin being fabricated of steel and having a natural spring bias, a. the spring bias of the pin material acting at the said bore restricing bends to develop sufficient frictional forces, between the pin and the bar construction which defines the bores to prevent the joint from being easily pulled apart.
