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.degree. 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.
