Abstract: An inflatable device with a liquid-powered air pump includes a pump housing a liquid chamber and an air chamber, each having an input port and an output port. A turbine axle extends between the liquid chamber and the air chamber. The end of the turbine axle, residing in the liquid chamber, includes a number of liquid turbine blades while the end of the turbine axle, residing in the air chamber, includes a number of air turbine blades. A nozzle, which is preferably adjustable, is connected to the input port to the liquid chamber. Introduction of liquid into the liquid input port turns the liquid turbine blades and thus the air turbine blades via the axle. Air is drawn from the air input port and forced through the air output port. The pump assembly may be connected to or integrated with an inflatable device to simultaneously fill a liquid container and a separate air bladder of the inflatable device.

Abstract: An infant activity center includes a bolster of a shape that will at least partially encircle an infant while providing an elevated playing surface. Preferably U-shaped, the bolster is made up of a plurality of dense foam pad sections encased and united in a removable, washable outer cover. A padded seating portion substantially traverses a center region defined by the pad sections. The upper surface of the cushion preferably includes a variety of toys secured thereto. The foam pad sections may include compartments or recesses for cups, toys or other items.

Abstract: A portable infant chair includes upper and lower resilient wire frame members. The upper frame member is made up of a back and seat support portion and a lower leg support portion, and the lower frame member is made up of a ground-engaging portion with opposite sides terminating in upwardly and rearwardly inclined portions. Rotational connectors secure upper extremities of the inclined portions to the upper frame member such that the sides of the lower frame member are selectively movable between erect and collapsed orientations. The sides of the lower frame member fold inwardly in crossed overlying relation to one another against the upper frame member in the collapsed orientation. A cross member includes one end pivotally connected to a rearward end of a first of the sides and an opposite end provided with a clip for detachable engagement with either a latch bracket on a rearward end of a second of the sides in an erect orientation or alternatively with the first side in a collapsed orientation.

Abstract: An infant seat unit includes a seat or harness disposed on a table, the table being resiliently mounted on a base unit at spaced circumferential intervals displaced away from the seat itself so that the seat and table are free to bounce up and down with respect to the base, and the seat also can be made to be rotatable with respect to the base.
