Patent number: 5144717Abstract: A double wheel caster for being rotatably mounted on a leg of a transport carrier includes a support rod having a center portion and opposite first and second end portions. The center portion of the support rod is rotatably positioned within an opening located in a wheel caster trailing housing. A pair of caster wheels are rotatably positioned on the first and second end portions of the support rod. Each caster wheel has an aperture generally centrally located therethrough and a plurality of fingers extending radially inward and into engagement with the support rod such that the caster wheels are frictionally mounted on the support rod. Upon movement of the transport carrier in a direction which forces one caster wheel to rotate faster than the other, the frictional mounting inhibits the one caster from freely rotating with respect to the other to thereby prevent shimmying.Type: GrantFiled: April 26, 1991Date of Patent: September 8, 1992Assignee: Graco Metal Products, Inc.Inventors: Devon T. Siesholtz, Nathaniel Saint

Patent number: 4811437Abstract: Foldable playyard comprising upper and lower frame assemblies. The lower frame assembly comprises a unitary central hub member, corner leg connecting members preferably in the form of support feet, and hub legs diverging radially outwardly from the hub member. The upper frame assembly includes corner rail connecting members and pairs of in-line side rails which are pivotably coupled at their outer ends to adjacent corner rail connecting members and at their inner ends to a medial rail connecting member. Corner legs interconnect and are freely coupled to the upper and lower frame assemblies. In one embodiment, the medial rail connecting member houses a hand releasable latch mechanism. In other embodiments, a hand releasable latch mechanism is rotatable with the side rails between latched and released positions. When the playyard is erected, the hub legs and side rails maintain the corner legs upstanding in a spread configuration.Type: GrantFiled: June 26, 1987Date of Patent: March 14, 1989Assignee: Graco Metal Products, Inc.Inventors: James M. Dillner, Nathanael Saint

Patent number: 4688850Abstract: An infant seat which serves as a rocker, car safety seat, carrier and swing seat. The seat includes a plastic shell having a seat portion, a backrest portion and a pair of hook members for threadably receiving and retaining a seat belt. A foldable rocker mechanism is coupled to the shell and is latchable in one or more positions so as to rockably support the seat on a flat support surface or provide a stable support for the seat on a car seat. A handle mechanism for carrying the seat includes a handle member rotatably coupled to the shell and latchable in a forward position. A bail is attachable to the handle so as to swingably support the handle from a windup swing mechanism when the handle is in the forward position.Type: GrantFiled: September 30, 1985Date of Patent: August 25, 1987Assignee: Graco Metal ProductsInventors: Alan Brownlie, Nathaniel Saint

Patent number: 4573224Abstract: A folding playpen having frame portions and platform sections which pivot in opposite directions as leg frames move between extended and collapsed positions. Angled links assisted by meshed gears on at least one pair of leg frames cause said pivotable movement to eliminate the problem of members pivoting inwardly when they should pivot outwardly.Type: GrantFiled: June 1, 1984Date of Patent: March 4, 1986Assignee: Graco Metal Products Inc.Inventor: David Saint

Patent number: 4452446Abstract: A battery-operated child's swing is driven by a motor with a worm mounted on the motor shaft. The worm drives a gear, on which is mounted a crank. The end of the crank is constrained in one sleeve of a two-way slider. A second sleeve of the slider, which is mounted at right angles to the first sleeve, receives one end of an over-travel torque spring. When the motor is energized, the worm turns the gear which drives the crank. The crank, via the slider, puts side pressure on the over-travel torque spring, directed first toward the front of the swing and then toward the rear of the swing. The force is applied above the horizontal pivot line of the swing carriage and causes a rocking motion in the carriage. The over-travel torque spring is stiff enough to transmit the driving force from the crank to the swing carriage while being resilient enough to twist, if necessary, due to stoppage of the motor to prevent damage to the mechanism in the event that the motor is stopped while the carriage is still swinging.Type: GrantFiled: September 30, 1982Date of Patent: June 5, 1984Assignee: Graco Metal Products, Inc.Inventor: David Saint
