Abstract
A book support of the type used to support books of an old or delicate construction allows the books to be opened and held steadily. The support (10) comprises an upright platform (11) which is rotatable about an axis (A) and a horizontal platform (12) which is suspended below the plane (A-C) in which the axis (A) lies. Horizontal platform (12) is rotatably suspended at the end nearest the axis (A) and at the end furthest from the axis (A). Thus, horizontal platform (12) can be moved upwards and away from vertical platform (11) as the pages of a book are turned from lying against horizontal platform (11) to lying against vertical platform (12).
Claims20
A book support comprising:
- a first, generally rectangular, book-supporting platform pivotable on a first pivot around a first axis (A) so as to be held at a predetermined angle relative to a plane (A-C) in which the first axis (A) is located;
- and
- a second, generally rectangular, book-supporting platform suspended below the plane (A-C) at (i) at least one position on a first line (B), which first line is approximately coincident with, and parallel to, the end of the second platform which is proximal the first axis, and (ii) at least one position on a second line (D), which second line is approximately coincident with, and parallel to, the end of the second platform which is distal the first axis,
- the second platform being movable on second pivots so that the first line (B) is rotatable around the first axis (A) and the second line (D) is rotatable around a second axis (C), which second axis (C) is located in the plane (A-C).
