Claims
I claim:
1. A crib comprising a member inflatable to form a body having a
rectangular floor and four planar sides forming a circumscribing
wall of even height, a horizontally disposed sleeve on each of the
four sides of the wall in the plane of said floor, and four
sectional, cooperative rigid rods one receivable in each of said
sleeves for removable retention in the plane of said floor and
projecting from each end of the sleeve whereby said body is
stabilized against overturning.
2. A crib comprising a member inflatable to form a body having a
rectangular floor and four planar sides forming a circumscribing
wall of even height, a circumscribing apron extending outward
laterally from the floor in the plane thereof, a plurality of first
pockets laterally spaced about the circumference of the wall
adjacent the upper edge at the corners thereof and opening towards
said apron a plurality of second pockets laterally spaced about the
circumference of the apron adjacent the outer end thereof and
opening towards said first pockets said first and second pockets
forming opposed pairs, and eight sectional rods each being
receivable at its ends in a separate pair of said opposed pockets
to lie in the planes of the sides of the wall whereby said body is
stabilized against overturning.
3. A crib as claimed in claim 1 in which the rods are telescopic
and releasably lockable in their extended position.
4. A crib as claimed in claim 2 in which the rods are telescopic
and releasably lockable in their extended position.
Description
The present invention relates to a baby's crib and more
particularly to a collapsible crib.
Collapsible baby's cribs are well known but they suffer from the
disadvantage that in their collapsed state they are bulky and
cannot readily be stored in a small space except by a time
consuming dismantling procedure.
The present invention overcomes this disadvantage by providing a
crib which is stable and yet is readily collapsible in all
dimensions. This is achieved by a structure comprising an
inflatable body having a circumscribing wall and a floor, and rigid
rod means adapted to extend outwardly from the body on each side
thereof whereby the body is stabilized against overturning.
An example embodiment of the invention is shown in the accompanying
drawings in which:
FIG. 1 is a perspective view of a crib;
FIG. 2 is a view in cross-section taken along the line 2--2 of FIG.
1; and
FIG. 3 is a perspective view of an alternate embodiment of a
crib.
The example embodiment shown in FIGS. 1 to 3 of the drawings
consists of a member inflatable to form a body 10 having a
circumscribing wall 11 and a floor 12. Wall 11 defines a
rectangular well 11a but other constructions such as a hexagonal
well would be suitable, as long as the lower portion of body 10 is
adapted to receive stabilizing means to be described. Body 10 may
be constructed of any suitable material which is impermeable to air
and flexible, such as sheets of thermoplastic material bonded
together at the seams. An example material which may be used is
polyvinyl chloride in sheets preferably of a thickness between
0.006 and 0.010 inch. Wall 11 may be slotted vertically to provide
apertures 13 which give the structure more the appearance of a
conventional baby's crib and provide air circulation within well
11a. A valve 14 of conventional construction, conveniently located
in body 10, preferably in the outside surface area of the body and
adjacent floor 12, allows the member to be inflated. Suitable webs
12a may be located within floor 12 of body 10 to allow the floor to
maintain a flat configuration when inflated.
Located along linear surfaces of wall 11 adjacent the bottom
portion of body 10 are a pair of tubular sleeves 15, one on each
end of the body, which may be formed of extra sheet material bonded
to the outer surface of walls 11. Each sleeve 15 is adapted to
receive and retain a rigid rod 16, preferably sectional and
telescopic, which when extended and releasably locked projects
beyond the sleeve outwardly in opposite directions from the
periphery of body 10. By locating an extended rod 16 at both ends
of body 10, the body is prevented from tipping by a child's weight
applied against the upper portion of wall 11 in the direction of
the rods.
To stabilize body 10 in a direction transverse to the alignment of
rods 16, further sleeves 17 and rigid, preferably sectional or
telescopic, rods 18 may be provided. Rods 18 should preferably lie
in the plane of rods 16 and for this purpose each rod 18 is
sectional with a central section 19 and a pair of detachable end
sections 20 each having a hump 21 intermediate its ends.
For use, the member forming body 10 is inflated through valve 14 by
suitable air pressure means. The circumscribing nature of wall 11
enables the structure to keep its crib-like shape when inflated.
Either before or after the member has been inflated, each rod 18 is
placed in a pocket 17 by first placing central section 19 in the
pocket and then snapping or otherwise connecting end sections 20 to
the central section. Each rod 16 is then connected or extended
(depending on whether it is sectional or telescopic) and inserted
into pocket 15 to extend outwardly from each end of the pocket. The
crib is now ready for use.
To collapse the crib, rods 16 and 18 are removed from pockets 15
and 17 and valve 14 is opened. By disconnecting or telescoping rods
16 and 18, and by folding the deflated member, these units may be
stored in a space of dimensions smaller than any dimension of the
crib when erected, which is another very important consideration
especially when travelling. It will be seen that the ease in
constructing and dismantling the device is also an important
advantage.
In the alternate embodiment of the invention shown in FIG. 3 of the
drawings a skirt or apron 30 replaces sleeves 15 and extends
laterally from the bottom of floor 12, circumscribing body 10.
Pockets 32 are located along the upper edge of wall 11 adjacent
each vertical edge of the wall and open downwardly. Further pockets
34 are located adjacent the outer edge of apron 30 to face pockets
32, forming pairs of opposed pockets. Each pair of opposed pockets
32, 34 are adapted to receive the ends of a sectional rod 36
whereby the rods extend outwardly and downwardly from the upper
corners of wall 11 to the outer edge of apron 30. In this manner
wall 11 is braced laterally to prevent the overturning of body 10
by a child's weight bearing against the inner surface of the wall.
Rods 36 are preferably telescopically collapsible and located in
pairs at each vertical edge of wall 11, the rods of each pair being
positioned approximately at right angles one to the other.
