Abstract
Abstract A fabric mounting track system which permits one to mount a fabric to cover a wall without the need to utilize weltings and other devices to cover unsightly parts of the system. The fabric mounting track consists of two parts, a back support plate and a hinge lock plate. The hinge lock plate has a straight portion at one end and a substantially circular portion at the other end forming a hinge. The hinge is disposed in a plane spaced from the straight portion. The back support plate also has a substantially circular portion at one end forming a larger hinge into which the smaller hinge of the hinge lock plate fits. Extending from the straight portion of the back support plate at an acute angle is a ledge, while the other end terminates in a straight portion forming a small angle, and may have its free end extending in the opposite direction. The hinge lock plate is provided with substantially equally spaced lancings punched out from the straight portion of the hinge plate. At intervals between a number of lancings, one of the lancings is larger in size. It will pierce the fabric to support it while the back support plate is hanging down from the hinge lock plate. Thereupon the hinge lock plate is rotated 180° so that the large size lancings will hook behind the ledge, while the small size lancings will impact the free end of the ledge, thereby forcing the fabric through the lancings. The lancings now support the fabric. The mounting track is capable of withstanding a fabric pull of at least ten to twelve pounds per inch and may withstand as much as twenty pounds' pull per inch. Various modifications of the fabric mounting track are also disclosed.

Claim 1
Independent Claim
189 words
In combination with a fabric mounting track for mounting a fabric on a wall of the t:ype including: (a) a hinge lock plate; (b) a back support plate; (c) said plates having means on one end for pivoting them through 180°; (d) said hinge lock plate having a row of large and small lancings; (e) said back support plate having ledge means protruding therefrom so that said small lancings impact said ledge means while said large lancings hook behind said ledge means when said plates face each other, thereby to lock said plates; and (f) an unlocking tool for unlocking said locked and facing plates, said unlocking tool consisting of an elongated handle and an enlarged front portion having a small protrusion extending at substantially 90° from said front portion along the front end thereof, said tool being of unitary construction, whereby said tool is capable of being inserted into the ends between said plates and rotated with respect to the planes of said plates to pry said plates apart, while said handle is being bent to avoid hitting the ceiling of the room to be covered with fabric.

Claim 3
Dependent Claim
255 words
A fabric mounting track for covering a wall with a fabric, comprising: (a) a back support plate; and (b) a hinge lock plate; said back support plate consisting of an elongated single sheet of metal having a first intermediate straight portion, a substantially arcuate segment of said back support plate having an inwardly bent free end, said end portion and free end forming a hinge for said hinge lock plate, a straight ledge portion extending from said intermediate portion and forming an acute angle with said intermediate portion and extending away from said hinge; said back support plate having its other free end bent upwards in the same direction as said ledge portion but at a smaller acute angle than that of said ledge portion with respect to a vertical parallel to said first intermediate straight portion; said hinge lock plate consisting of an elongated single sheet of metal having a substantially straight hinge lock portion along one end; a second intermediate straight portion bent at an acute angle with respect to a vertical through said first intermediate straight portion; and a third intermediate short straight portion substantially parallel to a straight end portion and being followed by an arcuate segment having a radius of curvature smaller than that of said arcuate segment of said back support plate; said circular outermost portion being spaced from a plane passing through said straight portion along one end, whereby said hinge lock and back support plates fit partially into each other to form a hinge rotatable through 180°.
