Abstract: A child exerciser device in which an integral seat and tray are adapted to bounce relative to a bouncer ring. The bouncer ring rotates relative to a cross piece member by means of a lazy susan mechanism. The cross piece includes pivotable legs which are adapted to be adjustably engaged in tubular members extending upward from a base member which allows the device to rock in only one back and forth direction. The top portion of the device is removable from the base member and can be disposed within the base member whereby the collapsed unit can be manually transported and stored.

Abstract: Apparatus for holding and carrying an infant in which a U-shaped handle is attached to a carrier and a second hand grip member is attached to the handle and lies in a substantially vertical plane which extends through the longitudinal axis of the carrier. The second hand grip member normally pivots about the U-shaped handle; however, if desired, it can be locked in place.

Abstract: A support assembly is provided for mounting a wheel to a frame member. The assembly includes a sleeve for telescopingly receiving a frame member, a collar for telescopingly receiving the sleeve, a housing for separable connection to the collar and for mounting to a wheel axle, and a locking member on the housing for engaging a recess in the sleeve in order to couple the housing to the sleeve.

Abstract: An infant walker comprising an infant carriage unit, a central anchor member including a central pivoting member, and an attachment arm connected to the infant carriage unit and releasably attached to the central pivoting member is provided for allowing an infant to walk only in a circular path about the central anchor member.

Abstract: A collapsible baby stroller with an improved lock mechanism for preventing accidental collapse is disclosed. The lock mechanism comprises two separate engagements which must be disengaged before the lock is released, thereby enhancing safety. A locking member which rotates about one tube of the stroller first must be disengaged from a pin against the bias of a spring before the locking member can be disengaged from another tube. Only after both precautions are exercised can the tubes of the stroller move relative to each other to effect collapse.

Abstract: A device for releasably securing a tray to a chair having two extending arms with a plurality of consecutive recessed grooves on the underside of each arm which comprises a one-piece pivot bar; a pivot element for pivotably connecting the pivot bar to the bottom of the tray; the pivot bar comprising an operable front portion forward of the pivot element, a back portion rearward of the pivot element, and at least two pins extending from the back portion for engaging the grooves; attachment elements proximate the pivot element for rotatably securing the pivot bar to the bottom of the tray; and a biasing element associated with the pivot bar for urging the pins toward the bottom surface of the tray and into corresponding grooves when the tray is positioned on the arms of the chair to secure the tray to said arms, whereby operation of the pivot bar in opposition to the biasing means causes the pins to retreat from the grooves.

Abstract: A collaphible structure suitable for use as a childrens' play yard. The collapsible structure includes opposing end members movably connected by articulated elongated members. By rotating the articulated elongated members, the elongated members can be folded to bring the end members into juxtaposition; thus, encasing a base, side walls and the elongated members of the play yard.
