Abstract: A mobile chair (10) includes a padded seat portion (12) which carries a backrest portion (13). At least five legs (15) support the underside of the seat portion (12) and are each provided with a caster assembly (16). A shelf (22) is carried by the legs (15) near the bottom thereof. A tray assembly (24) is pivotally carried on one of the legs (15) and is attachable to an adjacent leg (15) by a magnet (30) or the like.

Abstract: A page turning device (10) is provided having a motor housing (12), an activator switch (14) and a book platform (16). A motor (18) is carried within the motor housing (12) and includes a drive shaft (20) that carries a spring arm (24) that, in turn, carries a wiping finger (26). The book platform (16) positioning the upper portion of a book placed thereon underneath a spring arm (24) and the wiping finger (26). The placement of a book on the book platform (16) may be facilitated by a book holder (38). When a book is placed on the book platform (16), activating the activator switch (14) activates the motor (18) and causes the drive shaft (20) to rotate the spring arm (24) connected thereto from a rest position so as to bring the wiping finger (26) into contact with the exposed top page of the book. The motor (18) continues through one cycle before again coming to rest, rotating the drive shaft (20) and the spring arm (24) and wiping finger (26) attached thereto, through 360 degrees.

Abstract: A seat (10) especially adapted for use by a mechanic includes a frame (11) which carries a seat cushion (21) and a lower tray (22). A tray frame (35) removably carries an upper tray (30) and is pivotally attached to the frame (11) by a pivot assembly (40). The pivot assembly (40) includes a hollow rod (41) attached to the tray frame (35). A coil spring (42) which carries pivot pins (43, 44) is slidably received in the rod (41). The pins (43, 44) engage the frame (11) so that the tray frame (45) and the upper tray (22) carried thereby are pivotal from a first position generally under the seat cushion (21) to a second position at least partially out from under the seat cushion (21) for ready access to items carried by the upper tray (22). The frame (35) may be maintained in the first position by a fastener (45) carried by the frame (35) and engageable with the frame (11).

Abstract: A device (10) for inflating an object such as a ball (B) includes spaced arms (13, 14) carried by a bar (12). The arms (13, 14) are spaced a predetermined distance approximating the properly inflated diameter of the ball (B). An inflation needle (24) is positioned generally midway between the arms (13, 14) and is adapted to provide air under pressure, received through flexible tubing (26), to the ball (B). A clamp bar (28) is pivotally attached to one of the arms (13, 14) and has an aperture (33) therethrough to receive the tubing (26). When the ball (B) is being inflated, it will engage and pivot the clamp bar (28) until it pinches the tubing (26) to terminate the air flow to the needle (24).

Abstract: A machine (10) for projecting a ball, such as a volleyball (B), includes a longitudinally extending, pivotally mounted impact arm (27). A power spring (32) is attached to one end of the arm (27). A ramp (41) is provided on the arm (27) and is mounted angularly with respect to the longitudinal direction of the arm (27). A motor (34) has a rotating shaft (37) which carries a crank arm (38) having a roller (40) at the end. The roller (40) first engages the ramp (41) to extend the spring (32) and pivot the arm (27) and then disengages the ramp (41) so that the arm (27) pivots the other direction under the influence of the spring (32). A pivotally mounted cradle (25) holds a ball (B) in the path of the arm (27) so that the other end of the arm (27) strikes the ball (B). A shock absorbing system (47) engages the arm (27) after the ball (B) has been struck.
