Rocking chairs and other forms of rockers have been in use for centuries. Rockers have been designed and made for use by persons of all ages: adults, children and infants. Baby rockers differ in size from rockers used by older children and adults. In some cases, a baby rocker may be designed for use with a child of up to about six months. Safety of the infant and the need to keep the rocker clean and in good repair can present additional factors in the design of a baby rocker.
A baby rocker includes a frame, a left rocker plate, a right rocker plate, a frame cover, and straps connected to the frame cover to hold the frame cover in position on the frame. The left rocker plate is attached to a left side of the frame and has a curved left rocker rail. The right rocker plate is attached to the right side of the frame and includes a curved right rocker rail. The frame cover includes a cushion positioned on a top side of the frame, a left side flap, a right side flap, a head end flap, and a foot end flap. The straps connect the left side flap, the right side flap, the head end flap, and the foot end flap at an underside of the frame to hold the frame cover in position.
Frame cover 12 includes cushion 20, which is mounted on frame 14. Frame cover 12 has a fabric envelope containing a soft stuffing or matting material. As shown in
Left rocker plate 16L is attached to the left side of frame 14. Similarly, right rocker plate 16R is attached to the right side of frame 14.
Harness 18 is mounted on cushion 20 to secure the baby in position on cushion 20 while the baby is on baby rocker 10. Harness 18 is positioned approximately midway between head end H and foot end F of baby rocker 10. Harness 18 is a three-point harness with a padded fabric structure that includes divider 22, left wing 24L, and right wing 24R. Harness 18 can be connected to and disconnected from cushion 20 using left belt buckle assembly 26L and right belt buckle assembly 26R. The left and right legs are of the baby are positioned on opposite sides of divider 22.
Frame 14 includes left inner sidebar 28L, right inner sidebar 28R, head end outer crossbar 30 (with threaded ends 30L and 30R), head end inner crossbar 32 (with threaded ends 32L and 32R), foot end outer crossbar 34 (with threaded ends 34L and 34R), and foot inner end 36 (with threaded ends 36L and 36R). The head end of left inner sidebar 28L contains outer counterbored mounting hole 40L and inner counterbored mounting hole 42L. The foot end of left inner sidebar 28L contains outer counterbored mounting hole 44L and inner counterbored counting hole 46L. Similarly, right inner sidebar 28R contains corresponding counterbored mounting holes 40R, 42R, 44R, and 46R.
Left rocker plate 16L includes curved rocker rail 50L, left outer sidebar 52L, left head end leg 54L, left foot end leg 56L, left foot end notch 58L, left relief 60L, left handle 62L, and left handle slot 64L. Left outer sidebar 52L includes head end outer mounting hole 66L, left head end inner mounting hole 68L, left foot end outer mounting hole 70L, and left foot end inner mounting hole 72L.
Right rocker plate 16R is a mirror image of left rocker plate 16L. Right rocker plate 16R includes curved rocker rail 50R, right outer sidebar 52R, right head end leg 54R, right foot end leg 56R, right foot end notch 58R, right relief 60R, right handle 62R, left handle notch 64R. Right outer sidebar 52R includes head end outer mounting hole 66R, right head end inner mounting hole 68R, right foot end outer mounting hole 70R, and right foot end inner mounting hole 72R.
Assembly of frame 14, left rocker plate 16L and right rocker plate 16R makes use of threaded ends 30L, 32L, 34L, and 36L, threaded ends 30R, 32R, 34R, and 36R, spacers 80L, 82L, 84L, and 86L, spacers 80R, 82R, 84R, and 86R, internally threaded bolts 90L, 92L, 94L, and 96L, and internally threaded bolts 90R, 92R, 94R, and 96R. Assembly can be achieved using two hex keys (or Allen wrenches) 98 and 100.
During assembly, left inner sidebar 28L is mounted to cross bars 30, 32, 34, and 36 by inserting threaded ends 30L, 32L, 34L, and 36L into counterbored holes 40L, 42L, 44L, and 46L, respectively. Similarly, right inner sidebar 28R is mounted to cross bars 30, 32, 34, and 36 by inserting threaded ends 30R, 32R, 34R, and 36R into counterbored holes 40R, 42R, 44R, and 46R, respectively. Spacers 80L, 82L, 84L, and 86L are placed on threaded ends 30L, 32L, 34L, and 36L, respectively, that are extending beyond left inner sidebar 28L. Spacers 80R, 82R, 84R, and 86R are placed on threaded ends 30R, 32R, 34R, and 36R, respectively, that are extending beyond right inner sidebar 28R.
Left rocker plate 16L is positioned with left outer sidebar 52L aligned with and spaced from to left inner sidebar 28L by inserting threaded ends 30L, 32L, 34L, and 36L into mounting holes 66L, 68L, 70L, and 72L of left rocker plate 16L. Internally threaded bolts 90L, 92L, 94L, and 96L are inserted into mounting holes 66L, 68L, 70L, and 72L to engage threaded ends 30L, 32L, 34L, and 36L, respectively. Similarly, right rocker plate 16R is positioned with right outer sidebar 52R aligned with and spaced from to right inner sidebar 28R by inserting threaded ends 30R, 32R, 34R, and 36R into mounting holes 66R, 68R, 70R, and 72R of right rocker plate 16R. Internally threaded bolts 90R, 92R, 94R, and 96R are inserted into holes 66R, 68R, 70R, and 72R to engage threaded ends 30R, 32R, 34R, and 36R, respectively. Hex keys 98 and 100 are used to tighten the connections between the threaded ends and their respective internally threaded bolts.
Spacers 80L, 82L, 84L, and 86L are positioned between left inner sidebar 28L and left outer sidebar 52L of left rocker plate 16L to create left slot 102L. Spacers 80R, 82R, 84R, and 86R are positioned between right inner sidebar 28R and right outer sidebar 52R of right rocker plate 16R to create right slot 102R.
