Bassinet rocker

A structure which can be removably placed under the bed portion of a conventional bassinet and between its four legs such that the legs are lifted up off the gound by a sufficient distance to enable the bassinet to be rocked in either the head to toe rocking mode or cradle rocked, depending upon the orientation of the bassinet relative to the rocker sections of the present invention. A structure having at least one pair of parallel and separated rockers adjacent its lowermost portion is sized to fit beneath the bed and spaced to fit between the four legs of a conventional bassinet and oriented such that the pair of parallel and separated rockers are aligned in the same direction as the head and foot of the bassinet carriage, and the height of the structure is sized to cause the four legs of the bassinet to be lifted off the ground by a sufficient amount to permit the rockers to freely rock back and forth. In this configuration, the apparatus can be utilized with conventional modern day bassinets including those with cloth and frills on the exterior of the bassinet basket to convert the bassinet into a head to toe rocker. When the pair of parallel and separated rockers are aligned at an angle to and preferably generally perpendicular to the head and foot of the bassinet carriage, and the height of the structure is sized to cause the four legs of the bassinet to be lifted off the ground by a sufficient amount to permit the rockers to freely rock back and forth, then the apparatus can be utilized with conventional modern day bassinets including those with cloth and frills on the exterior of the bassinet basket to convert the bassinet into a cradle rocker.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to the field of apparatus to be used in 
conjunction with a baby's bassinet in order to convert the bassinet from a 
stationary object which can only be rolled from one place to another into 
a rocking apparatus which can be used to assist in rocking the baby to 
sleep while the baby is in the bassinet. The present invention further 
relates to the field of rocking apparatus which can be used to convert a 
stationary object into one which can be rocked from either head to toe or 
side to side. 
2. Description of the Prior Art 
In general, apparatus which can be used to convert a stationary object such 
as a baby carriage into a rocking object have been known in the prior art. 
The following six patents are illustrative of the known prior art in this 
field: 
A. U.S. Pat. No. 3,158,877 issued to Cooper on Dec. 1, 1964 for "Supporting 
Rocker Frame". 
B. U.S. Pat. No. 1,135,266 issued to Desper on Apr. 13, 1915 for 
"Attachment For Perambulators". 
C. U.S. Pat. No. 1,069,196 issued to Smith on Aug. 5, 1913 for "Device For 
Rocking Children's Cradles". 
D. Danish Pat. No. 33,328 issued to Jensen in 1924. 
E. U.S. Pat. No. 524,151 issued to Walker on Aug. 7, 1894 for "Rocker 
Attachment for Baby Carriages". 
F. French Pat. No. 777,134 issued to Flandrin in 1934. 
French Pat. No. 777,134 to Flandren illustrates a child's carriage which 
possesses an attachment transforming it into a rocker as depicted in FIG. 
4. It appears that the device contains an apparatus by which the carriage 
can be rolled, but at the same time the wheels are capable of being 
rotated up off the ground so that the rocking mechanism number 4 as 
illustrated in FIGS. 3 and 4 is able to rock the carriage. This device is 
in essence only a baby carriage with a mechanism by which the wheels can 
be rotated above the ground so that a secondary rocking structure can 
touch the ground and be used to rock the baby carriage. 
Danish Pat. No. 33,328 illustrates a cradle support for a child's cart 
body. It appears that the mechanism is a large rocking frame into which 
the child's cart body is placed. The cart body is supported within the 
rocking frame by the upper edges of the cart body such that the lower 
portion on which the baby rests is suspended in the air. This appears to 
be a cumbersome device and one which can only accommodate what is 
essentially a large basket without wheels. 
U.S. Pat. No. 524,151 to Walker discloses a rocker attachment which is 
capable of converting a baby carriage into a rocker. Essentially the idea 
is to have the wheels of the baby carriage fall into the four slots 
designated as B (see FIG. 3) and thereafter be locked in placed. In this 
way, the baby carriage can be converted into a rocker. With a shallow 
frame and small rocker compared to the baby carriage, it appears that this 
device is extremely unstable and the baby carriage could easily tip over. 
U.S. Pat. No. 1,069,196 to Smith discloses a complex apparatus wherein a 
child's crib can be mounted on a rocking apparatus through a spring 
attachment. The height of the rocker off the ground and the springs appear 
to make this device extremely unstable. 
U.S. Pat. No. 3,158,877 to Cooper discloses a supporting rocker frame. The 
apparatus discloses a frame for receiving a removable basket like bed 
portion of a baby carriage. While this device might be operable with a 
simple bassinet, one problem is that the bassinet fits well within the 
rocking apparatus such that the bassinet is adjacent the ground and the 
sidewalls rest well within the frame. Today's flowery bassinets have 
extensive cloth with frills surrounding the bassinet and such a device 
could not fit well within the rocking apparatus disclosed in the Cooper 
patent. In addition, today's modern bassinets are elevated above the 
ground and are attached to a base which further comprises folding wheels. 
Such a device could not fit within the frame of the Cooper patent. 
Therefore, while the general concept of a device for converting a baby 
carriage or a bassinet into a rocker has been discovered in the prior art, 
none of the prior art devices are functional with a modern bassinet which 
comprises a basket set on a base and having elongated folding legs and 
further comprises a fancy cloth covering and head covering with many 
frills. A significant need exists for such an apparatus which is capable 
of converting a modern baby's bassinet into a rocker. 
SUMMARY OF THE PRESENT INVENTION 
A bassinet is a baby's bed which often has a hood over one end. Modern day 
bassinets are often covered with cloth and frilly lace. The bassinet is 
typically mounted on a rigid structure which may contain four wheels or 
contain two stationary legs and two legs which have wheels at their 
bottom. One of the major problems with a bassinet mounted on the 
conventional stand having either four legs with wheels or two stationary 
legs and two legs with wheels is that it is extremely difficult to 
effectively and easily rock the bassinet. With modern day bassinets, 
rocking the baby in the bassinet is a major chore on the part of the 
mother because of the rigidity of the surface structure. The present 
invention is a structure which can be removably placed under the bed 
portion of a conventional bassinet and between its four legs such that the 
legs are lifted up off the ground by a sufficient distance to enable the 
bassinet to be rocked in either the head to toe rocking mode or cradle 
rocked, depending upon the orientation of the bassinet relative to the 
rocker sections of the present invention. 
It has been discovered, according to the present invention, that if a 
structure having at least one pair of parallel and separated rockers 
adjacent its lowermost portion is sized to fit beneath the bed and spaced 
to fit between the four legs of a conventional bassinet and oriented such 
that the pair of parallel and separated rockers are aligned in the same 
direction as the head and foot of the bassinet carriage, and the height of 
the structure is sized to cause the four legs of the bassinet to be lifted 
off the ground by a sufficient amount to permit the rockers to freely rock 
back and forth, then the present invention structure can be utilized with 
conventional modern day bassinets including those with cloth and frills on 
the exterior of the bassinet basket to convert the bassinet into a head to 
toe rocker. 
It has further been discovered, according to the present invention, that if 
a structure having at least one pair of parallel and separated rockers 
adjacent its lowermost portion is sized to fit beneath the bed and spaced 
to fit between the four legs of a conventional bassinet and oriented such 
that the pair of parallel and separated rockers are aligned at an angle to 
and preferably generally perpendicular to the head and foot of the 
bassinet carriage, and the height of the structure is sized to cause the 
four legs of the bassinet to be lifted off the ground by a sufficient 
amount to permit the rockers to freely rock back and forth, then the 
present invention structure can be utilized with conventional modern day 
bassinets including those with cloth and frills on the exterior of the 
bassinet basket to convert the bassinet into a cradle rocker. 
It is therefore an object of the present invention to provide a rocking 
apparatus which can be removably placed under the bed portion of a 
conventional bassinet and sized so as to fit between the four legs of a 
conventional bassinet and sufficiently tall to enable the legs of the 
bassinet to be elevated above the ground and to further comprise a rocking 
apparatus adjacent its lowermost portion and aligned parallel to the head 
and foot position of the bassinet basket to thereby convert the bassinet 
into a head to toe rocker. 
It is a further an object of the present invention to provide a rocking 
apparatus which can be removably placed under the bed portion of a 
conventional bassinet and sized so as to fit between the four legs of a 
conventional bassinet and sufficiently tall to enable the legs of the 
bassinet to be elevated above the ground and to further comprise a rocking 
apparatus adjacent its lowermost portion and aligned at an angle to the 
head and foot portion of the bassinet basket to thereby convert the 
bassinet into a cradle rocker. 
It is another object of the present invention to provide a bassinet rocker 
for converting any conventional bassinet into a rocker which can be used 
as both a head to toe rocker and a cradle rocker, whether the bassinet be 
the popular models sold at JC Penny R or Sears R or other less well known 
models.

their interior facing surfaces. Second middle lengthwise cross beam 32 
joins vertical posts 18 and 12 in the lengthwise direction. As shown in 
FIG. 2, in the preferred embodiment, second middle lengthwise cross beam 
32 is located on the exterior facing lengthwise surfaces 37 and 31 of 
vertical posts 18 and 12 respectively. It is also within the spirit and 
scope of the present invention to have second middle lengthwise cross beam 
32 connecting the two vertical posts 18 and 12 on their interior facing 
surfaces. 
The four posts 12, 14, 16 and 18 are also joined together at their tops by 
four cross beams which also serve as the base on which the bassinet is 
mounted. First upper lengthwise cross beam 40 joins vertical posts 14 and 
16 in the lengthwise direction and is joined to the posts at their 
respective tops. Second upper lengthwise cross beam 42 joins vertical 
posts 18 and 12 in the lengthwise direction and is joined to the posts at 
their respective tops. First upper widthwise cross beam 44 joins vertical 
posts 12 and 14 in the widthwise direction and is joined to the posts 
along their respective widthwise facing exterior surfaces 41 and 43 
respectively. As illustrated in FIG. 6, the ends of the two upper 
lengthwise cross beams 40 and 42 are flush with the exterior surfaces 41 
and 43 of vertical posts 12 and 14 and the top surfaces of 63 and 65 of 
first upper lengthwise cross beam 40 and second upper lengthwise cross 
beam 42 respectively are even with the top surface 61 of first upper 
widthwise cross beam 44. Second upper widthwise cross beam 46 joins 
vertical posts 16 and 18 in the widthwise direction and is joined to the 
posts along their respective widthwise facing exterior surfaces 45 and 47 
respectively. As illustrated in FIG. 6, the ends of the two upper 
lengthwise cross beams 40 and 42 are flush with the exterior surfaces 45 
and 47 of vertical posts 16 and 18 and the top surfaces of 63 and 65 of 
first upper lengthwise cross beam 40 and second upper lengthwise cross 
beam 42 respectively are even with the top surface 67 of second upper 
widthwise cross beam 46. Therefore, the respective top surfaces 61, 63, 65 
and 67 are all in the same plane and form a surface onto which can be 
placed the baby basket or bed portion of the bassinet. 
Supported on vertical posts 14 and 6 and attached to their outward 
lengthwise faces 33 and 35 respectively adjacent the bottom of vertical 
posts 14 and 16 is a first rocking member 70 comprising an arcuate lower 
surface 72. Supported on vertical posts 18 and 12 and attached to their 
outward lengthwise faces 37 and 31 respectively adjacent the bottom of 
vertical posts 18 and 12 is a second rocking member 74 comprising an 
arcuate lower surface 76. First rocking member 70 and second rocking 
member 74 are aligned generally parallel to each other such that their 
respective lower arcuate surfaces 72 and 76 are in the same plane and 
along which the bassinet rocker 10 can be rocked back and forth. Both 
rocking members 72 and 76 extend along the lengthwise direction of the 
bassinet rocker 10. 
First upper lengthwise cross beam 40 further comprises a pair of spaced 
apart notches 80 and 82 which extend out of its outwardly facing 
lengthwise face 51. Second upper lengthwise cross beam 42 further 
comprises a pair of spaced apart notches 84 and 86 which extend out of its 
outwardly facing lengthwise face 53. Notch 80 is generally parallel to and 
aligned with notch 84. Notch 82 is generally parallel to and aligned with 
notch 86. While each notch extends out of the outward face of the 
respective cross beam and only extends partially into the cross beam, it 
is also within the spirit and scope of the present invention for each 
notch to be a slot extending through the width of each cross beam. 
First upper widthwise cross beam 44 further comprises a pair of spaced 
apart notches 90 and 92 which extend out of its outwardly facing widthwise 
face 55. Second upper widthwise cross beam 46 further comprises a pair of 
spaced apart notches 94 and 96 which extend out of its outwardly facing 
widthwise face 57. Notch 90 is generally parallel to and aligned with 
notch 94. Notch 92 is generally parallel to and aligned with notch 96. 
While each notch extends out of the outward face of the respective cross 
beam and extends through the entire cross beam, it is also within the 
spirit and scope of the present invention for each notch to only extend 
partially into its respective cross beam. 
A bassinet 100 is shown mounted on the bassinet rocker 10 in the lengthwise 
or head to toe direction in FIG. 1. The exterior of the bassinet 100 
usually comprises a cloth skirt 102 and a hood portion 104 which is also 
covered with frilly lace 106. For purposes of illustrating the way the 
bassinet 100 can be mounted on the present invention bassinet rocker 10, 
the cloth skirt 102 and the hood portion 104 and frilly lace 106 thereon 
have been removed from the bassinet in the illustrations of FIGS. 7 and 8. 
Referring first to FIG. 7, the bassinet 100 comprises a bed or basekt 
portion 110 further comprising a flat bottom 112. The bassinet 100 also 
comprises 4 legs which are generally located at the four corners of the 
bassinet, two of which 114 and 118 are illustrated in FIG. 7. Leg 114 has 
a stationary bottom 116. A parallel stationary leg (not shown) is located 
at the remote left corner of the bassinet 100. Leg 118 has a wheel 120 at 
its bottom. A parallel leg with a wheel (not shown) is located at the 
remote right corner of the bassinet 100. In some bassinets all four legs 
have wheels at the bottom. In the head to toe rocking position as 
illustrated in FIG. 7, the bassinet 100 is placed onto the bassinet rocker 
10 such that the flat bottom 112 rests and all four cross beams, with the 
length of the bassinet bottom 112 resting along the length of the top 63 
of first lengthwise cross beam 40 and resting along the length of the top 
65 of second lengthwise cross beam 42. A portion of the width of bassinet 
bottom 112 rests along the length of the top 61 of first widthwise cross 
beam 44 and along the length of the top 67 of second widthwise cross beam 
46. The legs of the bassinet 100 can usually be folded up against the 
bottom of the bassinet 100 by a folding metal brace. There is one folding 
metal brace for each leg. In the illustration in FIG. 7, first leg 114 is 
folded up by folding metal brace 115 and second leg 118 is folded up by 
folding metal brace 119. The upper end of folding metal brace 115 rests 
against notch 92 and the upper end of folding metal brace 119 rests 
against notch 96. It will be appreciated that the two legs not shown also 
have folding metal braces which rest against notches 90 and 94 
respectively. At the four corners of the bassinet rocket 10 are four stop, 
2, 4, 6 and 8 respectively. The stops are supported on the face of the two 
widthwise cross beams. In the Figures, the four stops are shown on the 
inward face of the widthwise cross beams. Stops 8 and 2 are mounted on 
inner face 149 of first widthwise cross beam 44. Stop 8 abuts the outward 
lengthwise face 53 of second lengthwise cross beam 42. Stop 2 abuts the 
outward lengthwise face 51 of first lengthwise cross beam 40. Stops 4 and 
6 are mounted on inner face 151 of second widthwise cross beam 46. Stop 6 
abuts the outward lengthwise face 53 of second lengthwise cross beam 42. 
Stop 4 abuts the outward lengthwise face 51 of first lengthwise cross beam 
40. In an alternative embodiment, the four stops can be mounted on the 
outwardly facing lengthwise face of the two widthwise cross beams and 
therefore do not abut a lengthwise cross beam. The location of the stops 
will depend upon the width of the bassinet 100. This modification is 
designed to accommodate all sizes of modern day bassinets. In the 
embodiment illustrated in FIG. 7, the bassinet bed 110 is supported in the 
widthwise direction between the four stops 2, 4, 6 and 8 so that it cannot 
slide off the bassinet rocker 10 in the widthwise direction. The four 
braces set within the respective notches on the widthwise cross beams, as 
previously described, prevents the bassinet 100 from sliding off the 
bassinet rocker 10 in the lengthwise direction. 
A critical feature of the present invention is that the combined vertical 
height of each of the four vertical posts 12, 14 , 16 and 18 and the extra 
height added by the rocker members 70 and 72 is greater than the vertical 
height of the legs (114, 118 and the two not shown) such that the legs are 
elevated off the ground when the bassinet 100 is placed on the bassinet 
rocker 10. In this manner, the rocker members 70 and 72 can cause the 
bassinet rocker 10 and the bassinet 100 resting thereon to be rocked back 
and forth. In the illustration shown in FIG. 7, the bassinet is head to 
toe rocked. 
The alternative positioning for the bassinet 100 is illustrated in FIG. 8. 
In the cradle rocking position as illustrated in FIG. 8, the bassinet 100 
is placed onto the bassinet rocker 10 such that the flat bottom 112 rests 
and all four cross beams, with the length of the bassinet bottom 112 
resting along the length of the top 61 of first widthwise cross beam 44 
and resting along the length of the top 67 of second widthwise cross beam 
46. A portion of the width of bassinet bottom 112 rests along the length 
of the top 63 of first lengthwise cross beam 40 and along the length of 
the top 65 of second lengthwise cross beam 42. In the illustration in FIG. 
8, first leg 114 is folded up by folding metal brace 115 and second leg 
118 is folded up by folding metal brace 119. The upper end of folding 
metal brace 115 rests against notch 82 and the upper end of folding metal 
brace 119 rests against notch 86. It will be appreciated that the two legs 
not shown also have folding metal braces which rest against notches 80 and 
84 respectively. In the embodiment illustrated in FIG. 8, the bassinet bed 
110 is supported in the lengthwise direction between the four stops 2, 4, 
6 and 8 so that it cannot slide off the bassinet rocker 10 in the 
lengthwise direction. The four braces set within the respective notches on 
the lengthwise cross beams, as previously described, prevents the bassinet 
100 from sliding off the bassinet rocker 10 in the widthwise direction. 
Once again, a critical feature of the present invention is that the 
combined vertical height of each of the four vertical posts 12, 14 , 16 
and 18 and the extra height added by the rocker members 70 and 72 is 
greater than the vertical height of the legs (114, 118 and the two not 
shown) such that the legs are elevated off the ground when the bassinet 
100 is placed on the bassinet rocker 10. In this manner, the rocker 
members 70 and 72 can cause the bassinet rocker 10 and the bassinet 100 
resting thereon to be rocked back and forth. In the illustration shown in 
FIG. 8, the bassinet is cradle rocked. 
Described more broadly, the present invention an apparatus for holding and 
rocking a bassinet having a bed including a horizontally disposed bottom 
surface and legs supporting the bassinet bed, comprising: (a) four spaced 
apart vertical posts joined together by cross beams to form a vertically 
disposed structure; (b) four horizontal cross beams each joining a 
respective two vertical posts adjacent the tops of the posts to thereby 
form a horizontally disposed planar surface comprised of the four 
horizontal cross beams supported by the four vertical posts; (c) a pair of 
spaced apart generally parallel rocker members, each rocker member having 
an arcuate lower surface, and one rocker member attached adjacent the 
lowermost portion of two vertical posts and the other rocker member 
attached adjacent the lowermost portion of the remaining two vertical 
posts in a manner such that the lowermost arcuate portion of each rocker 
member lies in the same horizontal plane; and (d) the vertical distance 
from the lowermost point of the arcuate lower surface of a rocker member 
to the horizontal plane formed by the four horizontal cross beams is 
greater than the vertical height of the legs of the bassinet when the 
bassinet is placed upon the apparatus; (e) whereby the bassinet is placed 
upon said apparatus such that its horizontally disposed bottom surface 
rests on and is supported by the four horizontal cross beams such that the 
legs of the bassinet are raised above the ground to permit the rocker 
members to rock back and forth when a horizontal rocking force is imparted 
to the bassinet. 
The apparatus for holding and rocking a bassinet in further comprises four 
stop members, a respective stop member located adjacent the top of a 
respective one of the four vertical posts, to prevent the bassinet from 
sliding off the apparatus when the bassinet is rocked back and forth. 
The bassinet further includes a brace member attached to each leg of the 
bassinet to permit the leg to be folded up when the bassinet is not in use 
and each horizontal cross beam further comprises at least one notch to 
permit the uppermost end of a brace member to be accommodated within a 
notch to thereby provide further support for the bassinet when placed upon 
the four cross beams. 
In one embodiment, the bassinet is mounted on said four cross beams and 
positioned relative to the two rocker members such that the bassinet is 
head to toe rocked when the apparatus is rocked back and forth. 
In an alternative embodiment, the bassinet is mounted on said four cross 
beams and positioned relative to the two rocker members such that the 
bassinet is cradle rocked when the apparatus is rocked back and forth. 
In the preferred embodiment, the four vertical posts, all cross beams and 
the pair of rocker members are made of wood. 
The cross beams are attached to the vertical posts by any type of 
conventional fastening means such as screws, nut and bolt arrangements, 
nails, brads, tacks, or staples. The various dimensions of the components 
of the bassinet are a matter of design choice. The present invention can 
be sized to fit particular modern day bassinets sold by Sears R or JC 
Penny R or any other bassinet made by other manufacturers and sold through 
other retailers. By way of example only, the length L of a rocker member 
70 can be approximately 22 inches which its vertical height H from the 
lowermost point of the arcuate lower surface 72 to its outermost tip can 
be approximately 3 and 1/2 inches. The length of each upper widthwise 
cross beam can be approximately 18 and 1/2 inches and can be approximately 
1 and 1/2 inches in height and approximately 3/4 inches thick. The length 
of each upper lengthwise cross beam and each middle lengthwise cross beam 
can be approximately 14 and 3/8 inches in length, approximately 1 and 1/2 
inches in height and approximately 3/4 inches thick. The length of each 
lower widthwise cross beam can be approximately 15 and 1/4 inches long, 
approximately 1 and 1/2 inches in height and approximately 3/4 inches 
thick. Each stop member can be approximately 2 and 1/4 inches in maximum 
height by 1 and 5/8 inches in maximum width. Each vertical post can be 
approximately 15 and 3/4 inches in length, approximately 1 and 1/2 inches 
in height and approximately 3/4 inches thick. For certain large models of 
bassinets, the length of each vertical post can be approximately 17 
inches. The other dimensions remain the same. Each notch can be 
approximately 3/4 inch to 1 inch wide. Notches on the lengthwise cross 
beams can begin approximately 1 and 3/4 inches from each end and notches 
on the widthwise cross beams can begin approximately 3 and 3/4 inches from 
each end. It is emphasized that these are merely representative dimensions 
and other dimensions are certainly within the spirit and scope of the 
present invention. 
Of course the present invention is not intended to be restricted to any 
particular form or arrangement, or any specific embodiment disclosed 
herein, or any specific use, since the same may be modified in various 
particular or relations without departing from the spirit or scope of the 
claimed invention hereinabove shown and described of which the apparatus 
shown is intended only for illustration and for disclosure of an operative 
embodiment and not to show all of the various forms or modification in 
which the invention might be embodied or operated. 
The invention has been described in considerable detail in order to comply 
with the patent laws by providing full public disclosure of at least one 
of its forms. However, such detailed description is not intended in any 
way to limit the broad features or principles of the invention, or the 
scope of patent monopoly to be granted.
