Abstract
Abstract A rockable infant seat/cradle includes a rotatably positionable handle secured to the opposed side walls of an integrally molded infant supporting shell. The shell comprises a curved underbelly, oppositely disposed side walls extending transverse to the underbelly and apertured rocker panel walls integral with and spaced outwardly of the side walls. A mechanism, secured to opposed, distal ends of the handle, extends through the apertures in each rocker panel and is adapted to normally lock the handle in any one of a plurality of positions. The handle locking mechanism includes a gear having a plurality of axially extending teeth, a gear retaining ring having a plurality of apertures through which the gear teeth normally extend, and a coil spring which normally biases the gear teeth into a gear ring aperture-engaging condition. The mechanism is responsive to selective axial pressure to space the gear teeth axially of the gear ring apertures so that the handle may be rotated to any one of the plurality of positions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
259 words
A rockable infant seat/cradle comprising: a body-receiving and supporting shell, said shell having an elongated bottom surface and opposed sidewalls, the lowermost edges of said sidewalls being curved along the length thereof to support said shell on an associated support surface while permitting rocking movement thereof relative to such surface; generally U-shaped handle means having elongated leg portions rotatably secured to opposite sides of said shell; gear means to effect manual rotation of said handle means to various positions relative to said shell, thereby to permit carrying said shell or to position said shell in rockable or various fixed positions relative to the underlying associated support surface; said gear means including a gear fixedly secured to the distal end of each leg portion of said handle, each said gear having a plurality of axially extending teeth; a gear-retaining ring affixed to the respective opposed sidewall of said shell, said retaining ring including a plurality of axially extending apertures therethrough, through which said gear teeth normally extend, thereby to lock said handle in a fixed position relative to said shell; and means for normally biasing the respective gears and the handle legs to which said gears are secured in an engaged position wherein the gear teeth extend through the gear ring apertures, the gears being axially displaceable relative to said gear-retaining rings to space the distal ends of said gear teeth axially of the gear ring apertures whereby the handle may be rotated about the axes thereof to permit selective rotatable movement of said handle means relative to said shell.
Claim 2
Dependent Claim
259 words
A rockable infant seat/cradle comprising: a body-receiving and supporting shell, said shell having an elongated bottom surface and opposed sidewalls, the lowermost edges of said sidewalls being curved along the length thereof to support said shell on an associated support surface while permitting rocking movement thereof relative to such surface; generally U-shaped handle means having elongated leg portions rotatably secured to opposite sides of said shell; gear means to effect manual rotation of said handle means to various positions relative to said shell, thereby to permit carrying said shell or to position said shell in rockable or various fixed positions relative to the underlying associated support surface; said gear means including a gear fixedly secured to the distal end of each leg portion of said handle, each said gear having a plurality of axially extending teeth; a gear-retaining ring affixed to the respective opposed sidewall of said shell, said retaining ring including a plurality of axially extending apertures therethrough, through which said gear teeth normally extend, thereby to lock said handle in a fixed position relative to said shell; and means for normally biasing the respective gears and the handle legs to which said gears are secured in an engaged position wherein the gear teeth extend through the gear ring apertures, the gears being axially displaceable relative to said gear-retaining rings to space the distal ends of said gear teeth axially of the gear ring apertures whereby the handle may be rotated about the axes thereof to permit selective rotatable movement of said handle means relative to said shell.
Claim 3
Dependent Claim
57 words
A seat/cradle as in claim 1, wherein the teeth are spaced radially of and equa-angularly about the axis of the gear and extend axially from one side of the gear; and the apertures of the gear-retaining ring are of the same radial and angular spacing as the radial and axial spacing of the teeth of the gear.
Claim 4
Dependent Claim
24 words
A seat/cradle as in claim 2, wherein sixteen teeth are provided on the gear and sixteen correspondingly shaped apertures are provided on the ring.
Claim 5
Dependent Claim
40 words
A seat/cradle as in claim 1, wherein the distal end of each leg of the handle includes an inwardly extending, non-circularly shaped hub which is rotatably secured to and closely surrounds an outwardly extending, similarly shaped hub of the gear.
Claim 6
Dependent Claim
26 words
A seat/cradle as in claim 4, wherein the central opening in the gear-retaining ring is sized to receive therein the inwardly extending hub of the handle.
Claim 7
Dependent Claim
87 words
A seat/cradle as in claim 1, wherein the infant receiving and supporting shell further includes opposed rocker panel walls spaced outward of the opposed side walls; the gear retaining ring including a circular wall extending axially from both sides of the central ring, the circular ring wall adapted to extend axially through the rocker panel wall and to abut and be secured to the side wall of the shell, and an inwardly extending handle flange adapted to surround the outwardly extending circular wall of the gear-retaining ring.
