Abstract
A novel sling assembly and corresponding method of stretching sling fabric are disclosed. The assembly preferably comprises a chassis with opposing rails connected by a cross bar. A sling frame having opposing stretch bars connected by a stretchable fabric is disposed over the chassis in a pre-assembled position. A cam lock is inserted into a key hole cut into at least one of the rails; the cam lock is then rotated away from the central axis of the key hole. An engagement member extending from at least one of the stretch bars is then inserted into the key hole. The sling fabric may now be stretched by rotating the cam lock toward the central axis of the key hole to move the engagement member along the key hole until the fabric is taut. The taut fabric is held in place by the engaged cam lock, whereby the assembly is kept in its stretched, fully assembled position. The invention's unique structure thus advantageously makes sling fabric replacement convenient, quick, and without the need for special tools.
