  • Patent number: 4051210
    Abstract: A process for the combination of pneumacel fiber and synthetic elastomeric foam is provided that yields highly desirable, composite cushioning structures. A compressed, resin-bonded pneumacel batt is pre-expanded and combined with a precursor of an elastomeric foam under conditions leading to minor but definite penetration of the batt by the foam to give durably unitary cushioning with the best features of both materials.

  • Patent number: 4045045
    Abstract: A foldable child walker includes two inverted U-shaped frame members pivotally joined at intermediate points in a scissor-like fashion. The lower, or free, ends of the legs of the frame members are pivotally mounted to an annular base supported on a plurality of castered wheels. A flexible seat is suspended from the upper lateral portions of the frame members. Various mechanisms allow folding of the walker into a flat, compact package, convenient for storage or carrying. For example, in one embodiment, one of the two frame members has telescoping legs which are locked in selected positions of adjustment by spring-loaded release buttons to maintain the walker in selected upright positions above the base. When the walker is unoccupied, each button can be released to fold the frame members into a flat position against the base. In another embodiment, the legs in one of the two frame members are articulated below the pivotal connection the other frame member.

  • Patent number: 4019756
    Abstract: There is disclosed a baby walker to be used by a child wherein the body of the child is supported above the ground so that the feet of the child are in contact with the ground, thus permitting the child to propel the baby walker. The baby walker comprises means for permitting the walker to be collapsed or expanded, and means for locking said collapsing and expanding means to fix top and bottom members of the baby walker in a desired one of several positions. In this manner, the seat supporting the child is adjustable so that the distance to the ground may be controlled for different sized children, or for the same child over a period of growth.

  • Patent number: 4018439
    Abstract: A training device for ice skaters includes a body enclosing rectilinear frame and pairs of front and rear supp.ort legs depending from the frame. Runners are provided at the lower extremities of the support legs and at least the runners on the rear support legs are rotatable. Springs operatively connect the rotatable runners and their associated support legs such that during the forward movement of the trailing device the rotatable runners are caused to rotate against the bias of their respective springs into an orientation parallel to the direction of movement and when the training device is stationary the rotatable runners are biased by the springs towards an orientation substantially perpendicular to the longitudinal axis of the training device.
