发明名称 Portable reading magnifier
摘要 A magnifying system is provided to aid in the viewing or reading of book, papers or similar documents by those with impaired vision. A magnifying lens with approximate overall dimensions of eight by eleven inches is supported in an attractive wood or plastic frame of various designs and is supported by a series of four legs in each corner. The legs are adjustable in length by the use of a spring-based telescopic adjustment system that allows the user to adjust for different parameters such as strength of magnification, object size, level of vision impairment and the like. The legs also fold over against the frame in a manner similar to a card table to allow the invention to be carried in a case, a briefcase or just allow for easier transportation with reduced risk of damage.
