Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates generally to improvements in infant
cribs. More particularly, the invention pertains to an infant crib
employing tensioned netting defining resilient and foraminous
sidewalls in a crib, in lieu of slats, rods, or other rigid
sidewall structures.
[0003] 2. Description of the Prior Art
[0004] U.S. Pat. No. 2,128,978 represents a typical infant crib
that has been in use for many years. For the purpose of confining
and restraining an infant, conventional cribs used a plurality of
vertical slats 12 in combination with upper and lower frame or rail
pieces. The slats 12 are close enough to each other to prevent the
infant from slipping between them, and high enough to prevent the
infant from crawling over the top rail piece. The peripheral wall
created by the vertical slats allows light and air to enter the
crib and permits visual contact between the infant and the
caretakers. A bottom pad 20 fits within the confines of the
peripheral wall, and padded side wings 22, such as that shown in
the '978 patent, may be provided to extend above the surface of the
bottom pad 20. The resulting padded enclosure is designed to
provide a comfortable floor while preventing potentially injurious
contact between the infant and the rigid vertical slats 12.
[0005] Crib designs further evolved, because infant deaths
resulting from the use of prior art solid wall crib bumpers were
reported. The infant's head can become trapped between the mattress
and the lower edge of the bumper, presenting the danger of
asphyxiation. For example, in Patent Application Publication US
2012/0278995, a Crib Bumper System is shown which includes a bumper
having an inner first section and an outer second section. The
first section is formed from mesh material to provide improved
breathability, and safety, and the second section is formed from a
material that can be decorated. Notwithstanding these efforts, the
bumpers shown in this application still leave a gap between the
bottom of the bumper and the top of the mattress. Owing to the
exposed lower portion of the rigid slats 116, entrapment or impact
injury is still possible.
[0006] In Patent Application Publication US 2012/0284919, an
Aerated Bumper And Liner System For A Baby Crib is shown. This
arrangement uses a plurality of vertical posts or bars to form the
exterior structure of the crib, and an aerated bumper and liner
system on the inside of the exterior structure. The bumper and
liner system includes pads with apertures that allow for added air
circulation. The apertures extend generally from the median portion
of the pad down to the mattress level, the region where a baby
would come into contact with the pad while sleeping.
[0007] Yet another approach to minimizing injuries to infants in
cribs is shown in U.S. D613,091, showing two embodiments of Infant
Cribs. The cribs as disclosed, include what appear to be padded
coverings on the vertical rods forming the sides of the cribs. If
the padding is sufficiently soft and compliant, some protection
against injuries from hitting the rods would be afforded. The
padded rods are arranged in spaced relation to provide air
circulation and a degree of ingoing and outgoing visibility.
[0008] Entirely eliminating the vertical confining rods or slats in
a conventional crib is the design objective of a Slotless Safety
Infant Crib, made the subject of U.S. Pat. No. 8,256,041, issued to
Girdwain. In lieu of rods or slats, the crib of the '041 patent
employs a flexible planar member that spans each sidewall and each
end wall of the crib. The upper and lower edges of the planar
members are attached, respectively, to upper and lower rails by
means of receiving slots, adhesive, and mechanical fasteners. See,
column 3, lines 52-62. The side panels may also include a central
orifice in which a clear plastic panel is located, providing a
viewing window.
[0009] Infant playpens are generally related in function to infant
cribs, but they tend to be designed for breakdown, fold-up, and
portability. Playpens also are characterized by using flexible
material such as netting, fabric, or the like, for sidewalls and
end walls of the playpen. Typically, the netting material is
permanently attached to upper and lower tubular members of the
playpen, by providing sewn loops along the upper and lower edges of
the material.
[0010] An example of a Portable Playpen is shown in U.S. Pat. No.
4,376,318, granted to Cirillo. The playpen in the '318 patent has
rectangular upper and lower frames to which a flexible enclosure,
made from netting, is affixed. See, column 3, lines 56-62. The
fully deployed configuration is shown in FIG. 1, and the broken
down and folded up configuration is shown in FIG. 2.
[0011] A Multiple Purpose Convertible Playpen is disclosed in U.S.
Pat. No. 5,845,349, issued to Tharalson et al. Owing to its
construction, the playpen of the '349 patent may be converted into
a bassinet, a changing table, or a bed-side crib, or co-sleeper.
This design features a collapsible rigid frame, and sidewalls and
endwalls made from netting material.
[0012] In contrast to the above-discussed prior art, it is an
object herein to disclose an infant crib construction which
entirely eliminates the use of slats, rods, or other rigid vertical
members, and replaces such structures with tensioned netting,
providing foraminous and resilient crib sidewalls.
[0013] Furthermore, it is an object of the present invention to
provide an infant crib having tensioned netting for sidewalls, in
which the netting can be detached from the crib frame for cleaning
or replacement.
[0014] It is also an object herein to teach an infant crib with
tensioned sidewall netting, which comprises a number of separate
parts grouped into a compact package for shipping, which can be
quickly assembled on site by the user without special tools or
implements.
[0015] It is also an object herein to disclose an infant crib
without rigid member sidewalls, in which the mattress elevation can
be easily adjusted to a level appropriate for the infant, to
provide easy access to the infant while preventing the infant from
climbing out of the crib.
[0016] These and other objects will become apparent in the
specification and the detailed description of the preferred
embodiment, to follow.
SUMMARY OF THE INVENTION
[0017] An infant crib comprises a frame, preferably having four
corner posts connected to each other by means of upper and lower
bed rails. The bed rails are parallel to each other and arranged in
vertically spaced relation. The lower bed rail may include
decorative features such as paneling or a fabric covering, on its
exposed side.
[0018] The crib also includes a plurality of support arms,
preferably U-shaped in configuration. A first portion of each
support arm is detachably mounted to the inner corner of each
corner post, with the second portion extending inwardly toward the
center portion of the crib. At least two vertically offset sets of
lug connectors are provided on the corner posts, to mount the arms
at two different heights. The upper end of the second portion of
each support arm terminates in a horizontal plate. The four
horizontal plates of the support arms provide support for a
mattress support frame.
[0019] The mattress support frame has a lower side with corners
resting upon and engaging a respective one of the horizontal
plates. The support frame has a conventional wire and spring
construction, adapted resiliently to support a mattress. The
mattress overlies the upper side of the mattress support frame, and
is generally co-extensive therewith. When initially assembling the
crib, or modifying it later as the infant grows stronger and
taller, the user chooses the appropriate set of lug connectors on
the corner posts to support the mattress at the desired height.
[0020] The sidewalls of the crib are formed by peripheral netting,
preferably made from a continuous run of foraminous netting
material. The netting is tensioned to provide a restraint barrier,
but it is also sufficiently resilient to prevent injury to the
infant. The netting includes upper and lower edges provided with
respective connectors, preferably in the form of loops, sized and
configured to accommodate support and tensioning rods.
[0021] A plurality of rod hooks is mounted on the inside wall of
the lower rail. A plurality of rod receivers is mounted on opposing
sides of the corner posts, immediately beneath the upper rails.
Lower rods are passed through the lower loops in the netting, and
placed within respective rod hooks. Upper rods are passed through
the upper loops in the netting, then lifted over and around the
upper rails to place the netting under tension. Then, the upper
rods are placed within respective rod receivers, maintaining the
netting in a continuously tensioned condition. Resilient and
foraminous crib sidewalls are thereby defined by the tensioned
netting.
[0022] The infant crib may also include a bed skirt. The upper
edges of the bed skirt include connectors, preferably loops,
similar to those provided in the netting. Respective skirt rods are
passed through the loops, and then installed within respective
skirt rod receivers on the upper end of the support arms. A
peripheral decorative skirt for the infant crib is thereby
provided.
[0023] The skirt rods also are effective to direct and confine the
netting in the important region above the surface of the mattress.
This eliminates a gap that might otherwise exist between the
netting and the top surface of the mattress, and acts to maintain
the netting in spaced relation from the corner posts. Both of these
functions provide an additional measure of safety for the
infant.
[0024] Lastly, the skirt rods provide the additional utility of
laterally restraining the mattress from movement over or off of the
mattress support frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0037] Turning now to the drawings, FIG. 1 shows an infant crib 11
of the present construction, particularly designed to provide a
safe sleeping and play area for infants. Crib 11 includes frame 12
(See, FIG. 4), comprising a plurality of vertical corner posts 13
connected to each other by side upper rails 14, end upper rails 16,
side lower rails 17, and end lower rails 18. Upper rails 14 and 16,
and lower rails 17 and 18, are parallel with respect to each other,
and are arranged in vertically spaced relation. Lower rails 17 and
18 are preferably pre-assembled into panels at the factory, and
they may be provided with an array of vertical slats 19, other
ornamental features, or fabric.
[0038] The posts 13 and the rails 14, 16, 17, and 18 may be
fastened together by means of screws 15, shown in FIG. 4.
Typically, the main components of frame 12 will be fabricated at
the factory, and shipped unassembled in a compact package to the
consumer who then assembles them at home.
[0039] Crib 11 further includes a plurality of support arms 21,
shown in the greatest detail in FIG. 8. Although support arm 21 is
shown in FIG. 8 as being formed from two pieces into a generally
U-shaped configuration, arm 21 could be of unitary construction and
could assume different configurations than U-shaped and provide the
same utility. Each support arm 21 has a first portion 22 detachably
mounted to a respective corner post 13 and a second portion 23
extending inwardly from the corner post 13 toward the middle region
of crib 11 and then upwardly.
[0040] The upper end of first portion 22 includes a pair of upper
ears 24 provided with a variety of connectors. The first connectors
are a pair of lug apertures 26, one provided within each upper ear
24. Lug apertures 26 are preferably "keyhole" shaped, to facilitate
quick initial installation and subsequent removal and relocation of
support arms 21. The second connector is a "PEM" spring-loaded
plunger 27, press-fit into a bore (not shown) in one of the upper
ears 24. The third connectors are a pair of skirt rod receivers 28,
extending from each of the upper ears 24. Each receiver 28 includes
a finger 29, a cross-member 31, and a spring 32. Both finger 29 and
cross-member 31 include respective mating slots, so they can be
slid together and spot welded. Spring 32 slides snugly over the
assembled finger 29 and cross-member 31.
[0041] The lower end of first portion 22 also includes a pair of
lower ears 33. A pair of lug apertures 26 is also provided, one
within each ear 33. It should be noted that lower ears 33 are
oriented at 90.degree. with respect to each other, and oriented at
45.degree. with respect to the plane of first portion 22. It should
also be noted that upper ears 24 are also oriented at 90.degree.
with respect to each other, but oriented at 135.degree. with
respect to the plane of first portion 22. Lastly, it is evident
from FIG. 8 that first portion 22 and second portion 23 lie in the
same plane. The importance of these angular relationships will be
developed more fully below, in explaining how the support arms 21
are mounted in two different locations along the corner post
13.
[0042] After the corner posts 13 and the upper and lower rails 14,
16, 17 and 18 have been assembled, it is time to install the
support arms 21. To install the support arms 21 in an upper
position, an upper set of lugs, comprising post lugs 34 and rail
lugs 36 is provided. Each post 13 has a pair of upper post lugs 34,
while each end of side lower rail 17 and each end of lower rail 18
includes a single upper rail lug 36. (See, FIGS. 6 and 7, where a
single corner post 13 is shown assembled with lower side rail 17
and lower end rail 18). Post lugs 34 are mounted on sides 37 of
post 13, and rail lugs 36 are mounted on inner sides 38 of rails 17
and 18. FIG. 5 shows a support arm 21 installed over corner post
13, with the post lugs 34 secured within apertures 26 in upper ears
24, and the rail lugs 36 secured within apertures 26 in lower ears
33. Owing to the orientation of the first and second portions 22
and 23 of support arm 21 with respect to upper ears 24 and lower
ears 33, second portion 23 is directed inwardly, toward the center
portion of the crib 11, at an angle of approximately 45.degree.
from each inner side 38.
[0043] For the purpose of providing a safety locking mechanism for
support arm 21, previously mentioned spring-loaded plunger 27 is
provided. An upper rod bore 39 is provided on one side 37 of corner
post 13, immediately above a lug 34. When arm 21 is being
installed, plunger 27 is withdrawn until the lugs 34 are secured in
lug apertures 26. Then, the plunger 27 is released, and its rod
portion (not shown) enters upper rod bore 39. Although this
additional safety feature is optional, it does prevent the
inadvertent release of support arm 21 from its mounted
position.
[0044] To install the support arms 21 in a lower position, a lower
set of lugs, comprising post lugs 41 and rail lugs 42 is provided.
Each post 13 has a pair of lower post lugs 41 and each end of side
lower rail 17 and each end of lower rail 18 includes a single lower
rail lug 42. (See, FIGS. 5 and 6). Post lugs 41 are mounted on
sides 37 of post 13, and rail lugs 42 are mounted on inner sides 38
of rails 17 and 18. FIG. 7 shows a support arm 21 installed over
corner post 13, with the post lugs 41 secured within apertures 26
in upper ears 24, and the rail lugs 42 secured within apertures 26
in lower ears 33. A lower rod bore 43 is provided on one side 37 of
corner post 13, immediately above a lug 41, for the purpose of
receiving the plunger rod from spring-loaded plunger 27, after arm
21 is mounted in its lower position.
[0045] A horizontal plate 44 is located at the upper termination of
the second portion 23 of each support arm 21. The purpose of each
plate 44 is to support a corner of a mattress support frame 46 in
horizontal relation within the confines of the crib 11. Support
frame 46 is of conventional design, including a peripheral frame
47, wires 48, and springs 49. The configuration of plate 44 is not
critical, and it can be modified, for example, to engage in a more
positive manner with a corner of mattress support frame 46. A
simple modification would involve adding a curved corner portion
with short sidewalls extending therefrom, to emulate the
configuration of the support frame corner. This would assist in
maintaining mattress support frame 46 in a locked position.
[0046] At this juncture, it is easiest to install crib sidewall
means 51. Crib sidewall means 51 comprises a run of netting 52 of a
length and height sufficient to extend around an inner periphery of
crib frame 12. This inner periphery is generally defined by corner
posts 13, upper rails 14 and 16, and lower rails 17 and 18. The
netting 52 is preferably made from a material which is stretchable,
so it can be tensioned, and is also sufficiently resilient to
provide a measure of "push-back" from impinging forces. Netting 52
includes an upper edge provided with connectors, preferably in the
form of upper loops 53, and a lower edge provided with connectors,
preferably in the form of lower loops 54. (See, FIGS. 3, 9, and
10). Various types of equivalent connectors may be employed on and
along upper and lower edges, such as VELCRO.RTM., snaps, clips, and
various male and female couplers. It is desirable, however, that
the connectors be detachable, so that netting 52 can be removed as
needed.
[0047] Although the netting 52 is preferably a continuous run of
material, upper corner cutouts 56 and lower corner cutouts 57 are
provided. Upper corner cutouts 56 accommodate the upper ends of
corner posts 13. Lower corner cutouts 57 accommodate an arcuate
portion 58 of the second portion 23 of support arm 21, when support
arm 21 is mounted in its upper position. (See, FIG. 12).
[0048] Netting support and tensioning means are also provided.
These support and tensioning means are attached both to connectors
such as loops 53 on the upper lower edge of the netting 52 and to
connectors such as loops 54 on the lower edge of the netting 52.
Support and tensioning means are also mounted on the lower rails 17
and 18, and to corner posts 13, as will be explained below.
[0049] The inside walls of side lower rails 17 and end lower rails
18 include a plurality of lower rod hooks 59. A plurality of lower
rods 61 is also provided, each passing through a respective lower
loop 54. Cutouts 62 are provided in lower loops 54 and a small
portion of netting 52, to provide access to a lower rod 61 therein.
As shown most clearly in FIG. 10, each lower rod 61 is engaged
within respective lower rod hooks 59, securing the entire lower
edge of netting 52. Although hooks 59 are the preferred means of
attachment for rods 61, other equivalent securing means such as
VELCRO.RTM., snaps, clips, and various male and female couplers, as
mentioned above, would also work well.
[0050] A plurality of upper rods 63 is provided, each passing
through a respective upper loop 53 and having a short exposed
portion at each end of the loop. A plurality of upper rod receivers
64 is mounted on opposing facing sides 37 of corner posts 13,
adjacent and just below side upper rails 14 and end upper rails 16.
Each upper rod receiver 64 includes a pin 66 and a spring 67
extending around pin 66. A longitudinal groove 68 is preferably
located along the lower, outer edge of each rail 14 and 16. The
rods 63 may include a small bore (not shown) in each end, or hollow
tubes may be substituted for the rods. Also, it is a matter of
design choice whether receivers 64 are comprised of male or female
coupling structures.
[0051] With the lower edge of netting 52 secured, the upper edge of
netting 52, including loop 53 and upper rod 63, is drawn upwardly
over and around the top edge of a side upper rail 14, tensioning a
portion of netting 52. (See, FIG. 9). One exposed end of upper rod
63 is inserted into or over a respective upper rod receiver 64 in
one corner post 13, and the other exposed end of upper rod 63 is
inserted into or over a respective upper rod receiver 64 in an
opposing corner post 13. Spring 67 provides bias means tending to
urge each end of upper rod 63 away from a respective corner post.
Longitudinal groove 68 acts further to secure loop 53 and upper rod
63 in place. (See, FIG. 12).
[0052] An alternative construction that could be substituted for
the foregoing arrangement calls for rod slots in the top of the
corner posts 13, into which upper rod 63 would be placed after
netting 52 has been stretched and placed under tension. A locking
cap over the tops of corner posts 13 would restrain rod 63 from
popping out of the slots. Other structural equivalents for mounting
and tensioning the upper edge of netting 52 would be matters of
obvious design choice to an artisan of ordinary skill.
[0053] Now that one upper edge of netting 52 has been secured, the
user can proceed around the upper edges of crib 11, securing the
other upper edges of the netting 52 in place, using an identical
method and using the same netting support and tensioning means
described above. At this point, netting 52 has been sufficiently
tensioned and secured in place, to provide a tensioned and
resilient sidewall structure, entirely surrounding and closing off
the inner periphery of infant crib 11.
[0054] Since all of the support arms 21 have previously been
mounted on a respective corner post 13, the mattress support frame
46 can now be lowered into position within the crib 11, with its
lower portion resting over the plates 44. A conventional mattress
69, is then lowered over mattress support frame 46, completing the
floor components of the crib 11. It should be noted that the
support frame 46 and the mattress 69 are suspended within crib 11
entirely by plates 44 attached to second portion 23 of support arms
21, and they are completely free from any attachment to netting 52.
As will be discussed below, this feature allows support arms 21,
mattress support frame 46, and mattress 69 to be independently
moved into either an upper or a lower position, without concern for
interference from netting 52.
[0055] Infant crib 11 further includes a bed skirt 71 having
opposing side sections 72 and opposing end sections 73. Skirt 71
typically would include decorative design elements to enhance the
visual appeal of the infant crib 11. An upper edge of each skirt
section includes a connector, preferably in the form of a loop 74,
engaged by a respective skirt rod 76. This construction is shown in
greater detail, in FIGS. 5 and 7. Each skirt rod 76 is engaged by a
respective skirt rod receiver 28, which has previously been
described, and which is located on the upper ears 24 of support arm
21.
[0056] The location of skirt rods 76 is such that they are
approximately halfway up the sides of mattress 69, and in
contingent relation with the sides of the mattress 69. It is also
significant to note that with the skirt rods 76 located along sides
of mattress 69, the netting 52 extends between skirt rods 76 and
the sides of mattress 69. Thus, in addition to providing support
for the skirt 71, the skirt rods 76 also are effective to direct
and confine the netting 52 particularly in the important region
above the surface of the mattress 69. This direction and
confinement of the netting 52 eliminates a gap that might otherwise
exist between the netting 52 and the mattress 69, and acts to
maintain the netting 52 in spaced relation from the corner posts
13. Both of these functions provide an additional measure of safety
for the infant. Lastly, the skirt rods 76 provide the additional
utility of laterally restraining the mattress 69 from movement over
or off of the mattress support frame 46.
[0057] As is evident from a comparison between FIGS. 1 and 2,
mattress 69 can be installed at two different elevations, depending
upon the circumstances. When the infant is small and not able to
stand up readily, the upper position shown in FIG. 1 would likely
be selected. The parent can more readily access the infant, yet the
infant is unable to crawl out of the crib owing to limited strength
and agility. However, when the infant is older and able to stand
up, the lower position shown in FIG. 2 would be appropriate.
[0058] As explained previously, by mounting the support arms 21 at
a selected height, the mattress support frame 46 and the mattress
69 will assume a corresponding higher or lower height. Although the
present design discloses two sets of lugs at different elevations,
that is simply a matter of design choice, and additional lugs at
intermediate elevations could easily be added to provide more
selections for ultimate mattress height.
[0059] For replacement or cleaning the netting 52, the mattress 69
and the mattress support frame 46 are first removed. This provides
easy access to the lower edges of the netting 52, so lower rods 61
can be removed from lower rod hooks 59. Alternatively, upper rods
63 may be released from upper rod receivers 64, allowing the
removal of netting 52 from infant crib 11.
