Patent number: 6339304Abstract: A control (200) for an infant and child swing (40) driven by a direct current motor (160) includes a user interface (312) for selecting from a plurality of swing heights (or amplitudes), a microcontroller (400) having a processor (401), a swing angle indicator (118) having a light interrupter detector (210), and a music system (410). Processor (401) receives an output signal from light interrupter detector (210) for monitoring the current swing amplitude. At the end of each swing cycle processor (401) compares the current swing amplitude with the user selected maximum swing amplitude, and, if not substantially equal, generates a control signal to adjust the power output from motor (160) so that the current swing amplitude substantially equals the user selected maximum swing amplitude. This cycle-by-cycle adjustment produces a swing arc having improved accuracy and consistency.Type: GrantFiled: December 18, 1998Date of Patent: January 15, 2002Assignee: Graco Children's Products Inc.Inventors: Truman L.

A passenger carriage 28 is pivotably attached to the extended end of the boom. The shorter end of the boom includes a moveable counterweight 26 that is operable for raising the boom. The boom is then locked, the counterweight is moved, and the boom is released to swing freely. The movable counterweight includes first and second storage tanks 34 and 35, a counterweight fluid 36, and at least one pump 39 for moving the counterweight fluid between the first and second storage tanks. Passengers are loaded into the passenger carriage when the boom is in the down position. The boom is then raised by moving the counterweight fluid into the first storage tank. After the boom is raised, a brake is set to lock to boom in the raised position, and the counterweight fluid is moved into the second storage tank. The operator then lowers the boom by releasing the brake.Type: GrantFiled: May 8, 1997Date of Patent: October 27, 1998Assignee: SkyMax, Inc.Inventors: Mark A. Kleimeyer, Stat Cochron

Patent number: 5803817Abstract: An infant's swing is disclosed that has a frame, a swing arm, and a seat releasably mounted on the swing arm by a seat-to-frame coupler assembly that includes a pivot plate mounted to the back of the seat and a T-shaped connector mounted to the lower end of the swing arm. The connector is received in a mating cavity formed in the rear surface of the pivot plate, and the connector is engaged with the cavity by cooperation of slots in the cavity and posts on the connector. The pivot plate is pivotally mounted to the seat to permit the seat to pivot between a recline position and an upright position.Type: GrantFiled: August 15, 1996Date of Patent: September 8, 1998Assignee: Fisher-Price, Inc.Inventor: Carl M. Stern

Patent number: 5791999Abstract: An open top swing which includes a frame and mounting housings. A swing assembly depends from the pivot pins and includes a pair of spaced legs to which a swing is releasably attached for moving the swing closer to or away from the pivot pins to permit a change in the swing speed and the distance of the arcuate path that the swing will travel.Type: GrantFiled: September 4, 1996Date of Patent: August 11, 1998Assignee: Kolcraft Enterprises, Inc.Inventors: Charles W. Lauro, Thomas N. Koltun, Peter J. Myers

Patent number: 5709606Abstract: A rotatable swing set for providing amusement to children by spinning children secured within swing seats around a central point includes a main support post, a horizontally-disposed circular plate secured to the upper end of the support post for selective rotation thereon, and a plurality of arms radially mounted on the upper surface of the circular plate with the distal ends of the arms projecting outwardly past the circular plate and from which swing seats are suspended with one swing seat suspended from each arm. In addition, a support plate is mounted to the main support post subjacent the circular plate. The support plate supports thereon a drive motor, a chain linkage arrangement driven by the drive motor, and a drive wheel which frictionally engages the bottom surface of the circular plate.Type: GrantFiled: March 20, 1996Date of Patent: January 20, 1998Inventor: Richard Eugene Ehrman

Patent number: 5628689Abstract: A leg support structure for a foldable child swing that can be maintained in either an open position or a folded position and that is comprised of a housing, a plurality of support legs, and a leg brace for anchoring the legs and securing the legs within the housing in either an open or a folded position. In particular, the leg support structure is able to secure the legs in either the open position wherein the end of the legs are spread apart relative to each other and projected away from the housing or in the folded position wherein the legs are parallel to each other and the end of the legs are proximate and collapsed inwardly toward the housing.Type: GrantFiled: November 9, 1995Date of Patent: May 13, 1997Assignee: Graco Children's ProductsInventors: David Saint, James A. Sack

Patent number: 5573465Abstract: A passenger car sized pendulum is supported by a moving pivot point. The moving pivot point is forced horizontally by the angular movement of the pendulum. By resisting the horizontal force the angular movement of the pendulum is reduced. The preferred embodiment for resisting the horizontal force is a parallelogram assembly supporting a horizontal support platform. The parallelogram assembly has a damping cylinder resisting the horizontal force.Type: GrantFiled: February 13, 1996Date of Patent: November 12, 1996Inventors: William J. Kitchen, Kenneth G. Bird

Patent number: 5562548Abstract: A child swing including a support stand, a swing frame mounted on the support stand for reciprocating swinging movement along a swing arc in a forward swing direction and an opposite rearward swing direction, a base pivotably coupled to the swing frame for angular movement about a pivot axis between a forward-facing position facing in the forward swing direction and a side-facing position facing in a side direction extending at an angle to the forward swing direction, and a child seat coupled to the base to pivot therewith relative to the swing frame.Type: GrantFiled: November 4, 1994Date of Patent: October 8, 1996Assignee: Cosco, Inc.Inventors: Daniel R. Pinch, Dennis M. Turner

Patent number: 5525113Abstract: An open top swing assembly uses a unique swing drive mechanism and a control to provide three selective swing height settings. The assembly has a frame which provides an open top structure for ease of access and a trapezoidal shaped front base to provide foot clearance. The swing drive mechanism includes a drive sleeve rotatably mounted to an axle that operatively supports the hanger. A drive flange is mounted on the axle, with a drive flange coupling device positioned between the sleeve and the drive flange to provide a limited lost motion connection. The coupling device includes a hub member coaxially and rotatably mounted on the axle and at least one torsional spring mounted coaxially on the hub member. The hub member includes abutments for engaging with the drive flange, whereby torque applied to the sleeve is transferred to the axle. A crank driven by a motor is linked to the sleeve to oscillate the sleeve. The swing height control device can have a sensor for detecting the swing height or amplitude.Type: GrantFiled: October 13, 1994Date of Patent: June 11, 1996Assignee: Graco Childrens Products Inc.Inventors: Daniel R. Mitchell, Scott B. Caley, Truman Allison
