  • Document support and method of using same
    Patent number: 5407167
    Abstract: A document support (10) comprises an elastic cord (12) arranged in the shape of an endless loop (11), two elongated, tubular, high-friction spreaders (14a and b) through which the endless loop slidably extends, and a plurality of squeeze-type spring clips (16, 18) slidably and rotatably mounted on the endless loop. The document support is used by elastically expanding the endless loop, placing the high-friction spreaders on opposite edges (42) of an object (such as a seat back (38)) with the endless loop surrounding the stationary object and the spring clips positioned on a working side (47) of the stationary object, and allowing the elastic cord of the endless loop to elastically contract onto the stationary object. Documents are selectively attached to the squeeze-type spring clips by a person positioned on the working side of the stationary object.
