Abstract: A method and apparatus for moving book shelf units is disclosed. The book shelf units to be moved are of the type having vertical standards generally perpendicular to the ground and having a plurality of vertically spaced slots for supporting horizontal shelves between the standards. The vertical standards of the book shelf units are retainably engaged at positions therealong spaced from the ground. Moving devices are operatively connected to the engaging devices for cooperatively moving the engaging devices in a generally vertical manner relative to the ground. Therefore, movement of the engaging devices when retainably engaged to the vertical book shelf standards lifts and lowers the book shelf. Rolling devices are connected to the moving devices which enable the apparatus to be moved across the ground thereby moving the book shelf unit.

Abstract: An apparatus (10) for adapting the primary control button (23) in an elevator control panel (4) for use by handicapped people who are not able to normally reach the buttons (1-3). Apparatus (10) includes an auxiliary control panel (12) which mounts a plurality of auxiliary buttons (1a-3a). A first link arm (28) connects each of the auxiliary buttons (1a-3a) to one end of a pivot rod 22. A second link arm (30) connects the other end of the pivot rod 22 to a false primary button (1f-3f) located immediately in front of the primary buttons (1-3). The primary buttons can be actuated either by pushing inwardly on the false primary buttons (1f-3f) or by pushing inwardly on the auxiliary buttons (1-3) and causing rotation of the pivot rods (22).
