发明名称 Combination bookmark and page prop device
摘要 A combination bookmark and page prop device having a first elongated arm and a second elongated arm connected, end-to-end by a hinge. A space is created between the respective connected ends of the support arms so that rotation of the support arms in one direction about the hinge results in an abutting relationship between the arms creating a positive stop wherein the respective support arms are positioned at an angular relationship of approximately 80 DEG to 100 DEG . Each support arm is placed upon an opposed page of a bound document to prop it open. The respective support arms can be rotated about the hinge until they are fully extended, end-to-end, to function as a flat bookmark. The support arms can be further rotated about the hinge until the support arms are aligned parallel to one another to form a relatively flat bookmark approximately one-half the length of the fully extended marker. The support arms are constructed from a clear material to allow viewing of printed material through the arms. Each arm has a tacky coating on at least one exposed surface to prevent slipping when placed on pages.
