Abstract
Abstract False window muntin bar structure including unique muntin bar member interlock structure and retaining clip structure is disclosed. The interlock structure is operable in conjunction with hollow false muntin bars and includes an interlock member in the form of a cross adapted to fit within intersecting false muntin bar members with one end of the cross extending in each direction of extent of the intersecting false muntin bar members. The retainer clip for the false muntin bar structure includes a central abutment portion against which an end of the muntin bar member is abutted, a retaining portion extending from one side of the abutment portion for securing the end of the muntin bar member thereto, and a barbed portion extending from the other side of the abutment portion of the retainer clip for securing the retainer clip to the frame of a window in which the false muntin bar structure is installed. Modifications of the false muntin bar interlock member and the retainer clip are disclosed.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
123 words
False muntin structure for a window including a peripheral frame and a glazing panel comprising a grill, including a plurality of hollow intersecting linear members having sections rabbeted at each intersection to substantially half the depth of the linear members, which rabbeted sections are interfitted to form the intersections, said linear members having ends terminating adjacent the frame of the window structure, means for securing the linear members together at the intersections thereof, including a cross-shaped interlocking member having cylindrical portions at the ends thereof extending perpendicularly of the cross-shaped member, the ends of which interlocking member are received within the separate linear members at the intersection thereof, and retainer clips secured to the window frame and the ends of the linear members.
Claim 2
Dependent Claim
123 words
False muntin structure for a window including a peripheral frame and a glazing panel comprising a grill, including a plurality of hollow intersecting linear members having sections rabbeted at each intersection to substantially half the depth of the linear members, which rabbeted sections are interfitted to form the intersections, said linear members having ends terminating adjacent the frame of the window structure, means for securing the linear members together at the intersections thereof, including a cross-shaped interlocking member having cylindrical portions at the ends thereof extending perpendicularly of the cross-shaped member, the ends of which interlocking member are received within the separate linear members at the intersection thereof, and retainer clips secured to the window frame and the ends of the linear members.
Claim 3
Dependent Claim
88 words
Structure as set forth in claim 1 wherein the retaining clips include a central abutting portion adapted to be positioned against an end of a linear member, a portion extending from one side of the abutting portion for securing the end of the linear member thereto against transverse movement and a portion extending from the other side of the abutting portion adapted to extend into the window frame for securing the retaining clip and linear member held thereby to the window frame in contact with the glazing panel.
Claim 4
Dependent Claim
52 words
Structure as set forth in claim 2, wherein the portion of the retaining clip extending from one side of the abutting portion of the clip comprises a pair of spaced apart stepped leg portions havIng beads at the ends thereof which leg portions extend toward each other away from the abutting portion.
Claim 5
Dependent Claim
40 words
Structure as set forth in claim 2 wherein the portion of the retaining clip extending from the one side of the abutting portion of the clip comprises a substantially flat portion adapted to fit within a hollow false muntin member.
Claim 6
Dependent Claim
70 words
Structure as set forth in claim 2 wherein the portion of the retaining clip extending from the other side of the abutting portion of the clip includes a substantially flat portion having a relatively sharp edge and barb means extending upwardly from the substantially flat portion and toward the abutting portion at the end of the barb means to prevent withdrawal of the clip from the frame after installation thereof.
Claim 7
Dependent Claim
121 words
A retainer clip for false window muntins or the like comprising a central abutting portion for abutting the end of a false window muntin member, means extending from one side of the abutting portion for securing an end of a false window muntin member thereto, and means extending from the opposite side of the abutting portion of the retainer clip for securing the retainer clip to a window frame, including a pair of spaced apart triangular parts having grooves in one side thereof extending in a direction parallel to the abutting portion of the retaining clip and portions extending beyond the abutting portion of the retaining clip which extend at an angle with respect to the rest of the triangular parts.
Claim 8
Dependent Claim
121 words
A retainer clip for false window muntins or the like comprising a central abutting portion for abutting the end of a false window muntin member, means extending from one side of the abutting portion for securing an end of a false window muntin member thereto, and means extending from the opposite side of the abutting portion of the retainer clip for securing the retainer clip to a window frame, including a pair of spaced apart triangular parts having grooves in one side thereof extending in a direction parallel to the abutting portion of the retaining clip and portions extending beyond the abutting portion of the retaining clip which extend at an angle with respect to the rest of the triangular parts.
Claim 9
Dependent Claim
41 words
Structure as set forth in claim 6 wherein the portion of the retainer clip extending from one side of the abutting portion comprises a pair of spaced apart stepped leg portions having beads at the ends thereof extending toward each other.
Claim 10
Dependent Claim
27 words
Structure as set forth in claim 7 wherein the spaced apart stepped leg portions converge toward each other outwardly of the abutting portion of the retaining clip.
Claim 11
Dependent Claim
105 words
False muntin structure for a window including a peripheral frame and a glazing panel comprising a grill, including a plurality of hollow intersecting linear members having sections rabbeted at each intersection to substantially half the depth of the linear members, which rabbeted sections are interfitted to form the intersections, said linear members having ends terminating adjacent the frame of the window structure, means for securing the linear members together at the intersections thereof, including a cross-shaped interlocking member having ends received within the separate linear members at the intersection thereof, and retainer clips secured to the window frame and the ends of the linear members.
Claim 12
Dependent Claim
105 words
False muntin structure for a window including a peripheral frame and a glazing panel comprising a grill, including a plurality of hollow intersecting linear members having sections rabbeted at each intersection to substantially half the depth of the linear members, which rabbeted sections are interfitted to form the intersections, said linear members having ends terminating adjacent the frame of the window structure, means for securing the linear members together at the intersections thereof, including a cross-shaped interlocking member having ends received within the separate linear members at the intersection thereof, and retainer clips secured to the window frame and the ends of the linear members.
Claim 13
Dependent Claim
88 words
Structure as set forth in claim 9 wherein the means for securing the linear members together at the intersections thereof comprises a pair of substantially flat elongated portions in adjacent planes secured together in side by side relation in the form of a cross and cylindrical portions secured to each end of each elongated portion having the axis of generation thereof extending perpendicular to the cross formed by the flat elongated portions and extending primarily toward the plane of the elongated portion to which they are not attached.
Claim 14
Dependent Claim
