Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
71 words
An infant rocker comprising: a base; support means for supporting an infant; suspension means for mounting said support means on said base and allowing a predetermined degree of movement between the base and the support means substantially in a plane parallel to the base; and drive means for gently and rhythmically moving the support means relative to the base in an orbital motion pattern in said plane to lull an infant.
Claim 2
Dependent Claim
71 words
An infant rocker comprising: a base; support means for supporting an infant; suspension means for mounting said support means on said base and allowing a predetermined degree of movement between the base and the support means substantially in a plane parallel to the base; and drive means for gently and rhythmically moving the support means relative to the base in an orbital motion pattern in said plane to lull an infant.
Claim 3
Dependent Claim
18 words
An infant rocker as claimed in claim 1, wherein said drive means comprises a crank type drive mechanism.
Claim 4
Dependent Claim
16 words
An infant rocker as claimed in claim 1, wherein said drive means comprises an electric motor.
Claim 5
Dependent Claim
18 words
An infant rocker as claimed in claim 1, wherein said drive means comprises a low speed electric motor.
Claim 6
Dependent Claim
23 words
An infant rocker as claimed in claim 1, wherein said suspension means comprises springs extending between said base and said infant support means.
Claim 7
Dependent Claim
14 words
An infant rocker as claimed in claim 5, wherein said springs comprise conical springs.
Claim 8
Dependent Claim
30 words
An infant rocker as claimed in claim 1, wherein said infant support means comprises a flat support surface adapted to receive and support an infant container such as a bassinet.
Claim 9
Dependent Claim
83 words
An infant rocker as claimed in claim 7, wherein said infant support means comprises a one piece molded plastic element having a central flat tray area and a peripheral flange, wherein said flat support surface comprises said central flat tray area which is adapted to receive and support a bassinet or the like, and wherein said peripheral flange is provided extending upwardly from the bassinet support surface and then outwardly and downwardly in a skirt portion around the periphery of the infant rocker.
Claim 10
Dependent Claim
29 words
An infant rocker as set forth in claim 1 and further including timer means connected to said drive means for actuating said drive means for a predetermined time period.
Claim 11
Dependent Claim
92 words
An infant rocker comprising: a base; support means for supporting an infant, suspension means for mounting said support means on said base such that said support means is free to move in a plane parallel to said base; a motor connected to said base, said motor having a drive shaft with a vertical axis of rotation; and linkage means connecting said motor shaft to said support means such that rotation of said motor shaft produces a low speed orbital motion pattern of said support means in said plane to lull an infant.
Claim 12
Dependent Claim
92 words
An infant rocker comprising: a base; support means for supporting an infant, suspension means for mounting said support means on said base such that said support means is free to move in a plane parallel to said base; a motor connected to said base, said motor having a drive shaft with a vertical axis of rotation; and linkage means connecting said motor shaft to said support means such that rotation of said motor shaft produces a low speed orbital motion pattern of said support means in said plane to lull an infant.
Claim 13
Dependent Claim
26 words
An infant rocker as set forth in claim 10 and further including a timer connected to said motor for actuating said motor for a predetermined time.
Claim 14
Dependent Claim
68 words
An infant rocker comprising: a base; support means for supporting an infant; suspension means for mounting said support means on said base and allowing a predetermined degree of movement between the base and the support means substantially in a plane parallel to the base; and drive means for gently moving the support means relative to the base in a rhythmical orbital low speed motion pattern in said plane.
Claim 15
Dependent Claim
68 words
An infant rocker comprising: a base; support means for supporting an infant; suspension means for mounting said support means on said base and allowing a predetermined degree of movement between the base and the support means substantially in a plane parallel to the base; and drive means for gently moving the support means relative to the base in a rhythmical orbital low speed motion pattern in said plane.
Claim 16
Dependent Claim
31 words
An infant rocker as in claim 12 wherein said drive means imparts said orbital motion to said support means at a location displaced from a geometric center of said support means.
