Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
196 words
A window jamb or mullion for constructing bow or bay windows comprising two longitudinal frame members longitudinally slidably joined together and constructed so as to be hingedly joined together on one side thereof and variably slidably joined together on the opposite side thereof to form a boxlike or hollow frame construction for attachment to a window unit on each side of said mullion, said longitudinally slidably joined together longitudinal frame members being only longitudinally slidably disconnectable from each other, and each of said longitudinal frame members having means thereon for adjacently engaging a frame member of a window unit, and said hingedly connected longitudinal frame members being so constructed that a window unit attached to one side of said mullion may be positioned at any angle from about 90° to about 180° from a window unit attached to the other side of said mullion, said two longitudinal frame members comprising an arcuate member on one edge of one longitudinal frame member for variably slidably engaging a channel means on one edge of the other longitudinal frame member and channel means on one edge of said other longitudinal frame member for variably slidably receiving said arcuate means.
Claim 2
Dependent Claim
196 words
A window jamb or mullion for constructing bow or bay windows comprising two longitudinal frame members longitudinally slidably joined together and constructed so as to be hingedly joined together on one side thereof and variably slidably joined together on the opposite side thereof to form a boxlike or hollow frame construction for attachment to a window unit on each side of said mullion, said longitudinally slidably joined together longitudinal frame members being only longitudinally slidably disconnectable from each other, and each of said longitudinal frame members having means thereon for adjacently engaging a frame member of a window unit, and said hingedly connected longitudinal frame members being so constructed that a window unit attached to one side of said mullion may be positioned at any angle from about 90° to about 180° from a window unit attached to the other side of said mullion, said two longitudinal frame members comprising an arcuate member on one edge of one longitudinal frame member for variably slidably engaging a channel means on one edge of the other longitudinal frame member and channel means on one edge of said other longitudinal frame member for variably slidably receiving said arcuate means.
Claim 3
Dependent Claim
17 words
The window jamb or mullion of claim 1, wherein said longitudinal frame members are extruded aluminum shapes.
Claim 4
Dependent Claim
20 words
The window jamb or mullion of claim 1, wherein said longitudinal frame members are constructed of metal, plastic or wood.
Claim 5
Dependent Claim
28 words
The window jamb or mullion of claim 1, including an attachment means for securing each of said longitudinal frame members to a frame member of a window unit.
Claim 6
Dependent Claim
268 words
A window jamb or mullion for joining together a window unit on each side thereof comprising two longitudinal frame members longitudinally slidably joined together and constructed so as to be hingedly joined together on one side thereof and variably slidably joined together on the opposite side thereof, a hinge means extending longitudinally on one edge the length thereof of one longitudinally frame member for longitudinally slidably and hingedly receiving a receiving hinge means on one edge of the other longitudinal frame member, a receiving hinge means extending longitudinally on one edge the length thereof of said other longitudinal frame member for longitudinally slidably and hingedly receiving said hinge means on said one longitudinal frame member, arcuate means on one edge of said one longitudinal frame member opposite said hinge means for variably slidably engaging a channel means on one edge of said other longitudinal frame member opposite said receiving hinge means, channel means on one edge of said other longitudinal frame member opposite said receiving hinge means for variably slidably engaging said arcuate means on said one edge of said one longitudinal frame member, said longitudinally slidably joined together longitudinal frame members being only slidably disconnectable from each other, thereby providing when said longitudinal frame members are longitudinally slidably joined together an expandable hollow mullion for joining together a window unit on each side thereof, and said longitudinal frame members being variably positionable from each other whereby a window unit attached to one longitudinal frame member may be at any angle of about 90° to about 180° from a window unit attached to the other longitudinal frame member.
Claim 7
Dependent Claim
268 words
A window jamb or mullion for joining together a window unit on each side thereof comprising two longitudinal frame members longitudinally slidably joined together and constructed so as to be hingedly joined together on one side thereof and variably slidably joined together on the opposite side thereof, a hinge means extending longitudinally on one edge the length thereof of one longitudinally frame member for longitudinally slidably and hingedly receiving a receiving hinge means on one edge of the other longitudinal frame member, a receiving hinge means extending longitudinally on one edge the length thereof of said other longitudinal frame member for longitudinally slidably and hingedly receiving said hinge means on said one longitudinal frame member, arcuate means on one edge of said one longitudinal frame member opposite said hinge means for variably slidably engaging a channel means on one edge of said other longitudinal frame member opposite said receiving hinge means, channel means on one edge of said other longitudinal frame member opposite said receiving hinge means for variably slidably engaging said arcuate means on said one edge of said one longitudinal frame member, said longitudinally slidably joined together longitudinal frame members being only slidably disconnectable from each other, thereby providing when said longitudinal frame members are longitudinally slidably joined together an expandable hollow mullion for joining together a window unit on each side thereof, and said longitudinal frame members being variably positionable from each other whereby a window unit attached to one longitudinal frame member may be at any angle of about 90° to about 180° from a window unit attached to the other longitudinal frame member.
Claim 8
Dependent Claim
29 words
The window jamb or mullion of claim 5, including attachment means for securing each of said longitudinal frame members to the frame member of a window unit engaged thereon.
Claim 9
Dependent Claim
20 words
The window jamb or mullion of claim 5, wherein each of said longitudinal frame members is an extruded aluminum shape.
Claim 10
Dependent Claim
20 words
The window jamb or mullion of claim 5, wherein said longitudinal frame members are constructed of metal, plastic or wood.
