ABSTRACT:
A tensioned grating fastener that includes a deep draft saddle clip of U-shaped configuration that is engagable with a pair of load-support bars of a criss-cross configurated grating, an elongated foot that is provided with a vertical upstanding headed stud which projects through a hole of the saddle clip and a coil spring that is concentrically mounted under slight compression about the stud between the head of the stud and the base of the saddle clip. The depression of the headed stud compresses the coil spring and permits the foot to be rotated from a position in alignment with the saddle clip to a position at an oblique angle thereto, such that one end of the foot is beneath and in engagement with a flange of an underlying grating support member, and the opposite end, beneath and in engagement with one parallel load-supporting bars of the grating. Release of the depressed headed stud partially relaxes the compressed coil spring while ensuring tensioning of the clip engaged grating against the support flange to overcome vibration of the assembly of the grating to the flanged support.
