Page turner

#A. Field of Invention

#The invention relates to the field of devices which may be used to mechanically turn the pages of a musical composition or other work. More particularly, in the most preferred embodiment, the invention is a page turner for musical compositions that utilizes disks indexed to pages of the musical composition so that the pages of the composition may be turned by pressing a remote pedal with one's foot, the pedal causing a cable to turn, the turning of the cable causing a disk to rotate, and rotation of a disk causing the next page in sequence in the musical composition to turn.

#B. Prior Art

#FIG. 1 depicts a partial parts explosion view of a page disk housing assembly of the invention with a page disk exposed.

#FIG. 1a depicts a page disk assembly separate from its housing.

#FIG. 2 depicts the page disk housing assembly of FIG. 1 with a separator disk exposed.

#Referring to FIGS. 1-3, views of a page disk housing assembly 101 with page disks 102 and cable assembly 301 are shown. The assembly 101 includes a housing 103 which includes an upper housing member 103a and a lower housing member 103b. The housing 103 may include some type of attachment mechanism or clamp 104 to enable it to be attached to a music stand, piano or other stationary apparatus.

#The housing 103 (including 103a and 103b) has a recess 105 within its interior that accommodates page disks 102. The page disks 102 may be made of any suitable material, but polycarbonate is preferred. Page indexes 106 are includes either as an integral part of page disks 102 or as separate structures. Page indexes 106 are each affixed to a page of music to be turned (one page index per physical page of music) by an appropriate mechanism, such as adhesive. Positively indexing one page index to one page of music allows the invention to ensure that rotational movement of a page disk turns one and only one page of music.

#Each separator disk 201 includes a peripheral protrusion 107 that protrudes into and secures the separator disk 201 with respect to a slot 108 in the lower housing 103b. This prevents the separator disks 201 from turning. The separator disks 201 are not required to turn as they serve as separators between page disks and cannot be rotated by an adjacent page disk. Page disks and separator disks are sandwiched together in alternating fashion so that any two page disks are separated by a separator disk. Each separator disk 201 includes a clearance 202 so that a roller 302 can reach page disks 102 below any particular separator disk 201 without the necessity of turning the separator disk out of the way.
