发明名称 Book holder
摘要 A book holder for holding a book in open condition at a selected page comprises a pair of elongate limbs extending in opposite directions from a central zone and terminating at their free ends in reversely turned, page engageable fingers extending alongside and spaced from the associated limb. The limbs are coupled together in such a manner as to enable them to be adjusted relative to each other and vary the distance between the fingers. Supporting legs may be connected to the limbs to enable the book holder to support a book at an inclination to the horizontal. The legs preferably are pivoted to one another and to the limbs so as to enable the limbs and legs to be folded to a small-size unit when the holder is not being used.
