Claims
I claim:
1. The improvement in a crib frame for use with a conventional crib
structure, said crib frame comprising a generally rectangular
frame, a fixed panel provided adjacent one end of said rectangular
frame, and a movable panel provided in the remainder of said open
frame, said movable frame being hingedly connected to said fixed
frame for movement between a position wherein said movable frame
lies in the same plane as said rectangular frame from and to a
raised position wherein said movable frame has an end portion
opposite the hinged portion that can be elevated relative to the
horizontal frame for raising the head of an infant placed on a
flexible pad or mattress resting on the frame.
2. The improvement according to claim 1 said improvement further
characterized by two adjustable arms that are each fixed at one end
to the fixed frame and at the other end to the movable frame for
supporting said movable panel in a plurality of pre-selected raised
positions.
3. The improvement according to claim 2 wherein one or both said
panel portions (fixed and movable) are fabricated from plywood, and
wherein openings are provided in the plywood.
4. The improvement according to claim 3 further characterized by a
handle at said end portion for raising and lowering said movable
panel.
Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is entitled to the benefit of and
incorporates by reference essential subject matter disclosed in the
Brazilian Patent Application No: MU 8202270-4, filed on Oct. 1,
2002.
BACKGROUND OF THE INVENTION
[0002] This invention relates generally to an improvement in the
frame provided in an otherwise conventional child's crib for
supporting a mattress of a like. More particularly, this invention
relates to an improved crib frame that includes a portion which can
be varied in angular relationship to the frame so as to avoid any
problem with regard to a newborn or infant child being injured or
otherwise incapacitated by asphyxiation or reflux from the
consumption of a meal insufficiently digested.
SUMMARY OF THE INVENTION
[0003] In order to provide any mattress in the crib so that a
portion of the mattress is inclined, the present invention provides
a frame especially designed to fit in the crib supports for the
conventional mattress support structure. That frame has a portion
or section which is adjustable relative to the generally horizontal
frame itself, and a convenient means for supporting the adjustable
section or portion so that the caregiver can conveniently provide a
proper angular relationship between the adjustable section and the
fixed portion of the frame.
[0004] A rectangular frame is provided in a suitable size to fit a
standard child's crib, and the frame includes longitudinally and
laterally extending girders joined at their adjacent end portions
to provide and open rectangular frame. The frame has a portion or
segment fitted with a fixed platform, and also includes a movable
portion joined to the fixed portion and pivotable on a line
parallel to the lateral girders for movement between the position
where is it coplanar with the frame through any number of raised
positions wherein this movable portion or segment defines an
angular relationship with the horizontal frame for the purposes and
objects described above.
BRIEF DESCRIPTION OF THE DRAWINGS
[0005] FIG. 1 is a perspective view of a crib frame constructed in
accordance with the present invention with a movable section
inclined relative to the horizontal portion.
[0006] FIG. 2 is a perspective view illustrating the crib frame of
the present invention in the lowered position such that a mattress
or other pad provided in the crib will rest in parallel
relationship to the crib frame.
DETAILED DESCRIPTION OF THE DRAWINGS
[0007] See now to the specific disclosure of FIGS. 1 and 2 in
greater detail, a rectangular frame 1 is provided, and comprises
longitudinally extending segments 1a and 1b as well as laterally
extending parallel rail segments 1c and 1d joined together at their
adjacent end portions in conventional fashion.
[0008] A horizontally extending panel 3 is provided adjacent to the
lateral frame element 1c to define an opening between its inner
edge 3a and the opposite lateral frame member 1d.
[0009] In this opening of the frame, defined between the edge 3a of
panel 3 and the lateral member 1d, is provided a hinged panel
section 7 having one edge 7a provided alongside the edge 3a of the
fixed panel 3, and maybe hinged thereto by a conventional piano
hinge (not shown) or the equivalent. As shown a pivot pin 6 is
provided in the longitudinal girders, 1a and 1b for pivotably
supporting the lower end of the panel 7 as a result of providing
openings (not shown) in the panel's side girders 7c and 7d.
[0010] The panel 7 includes longitudinally extending side members
7c and 7d that cooperate with the upper members 7b to support the
panel 7, and these members 7c, 7d and 7b define a U-shaped
sub-frame that fits within the opening defined by the fixed frame
1.
[0011] Still with reference to FIG. 1, the moveable U-shaped frame
7c, 7d and 7b is provided with a pair of adjustable support arms 8
that each include a locking element 9, such that elements 8 and 9
telescope to adjustably position the U-shaped frame in a range of
angular positions relative to the horizontal frame. Preferably,
element 9 defines a series of spaced panels that allow a ratcheting
action on element 8 to allow the panel 7 to be held in any one of a
plurality of angular positions. This ratcheting action may require
lifting the panel 7 to the fully raised position before lowering it
to the desired position.
[0012] Note that the side rails 7c (and 7d) include recesses for
receiving the adjustable arm 8/9 when the panel 7 is provided
within the horizontal frame 1 as described above.
[0013] Finally, a handle 10 may be provided on the U-shaped frame
so as to facilitate raising and lowering this movable frame.
Preferably, the arms 8/9 are designed to require that the U-shaped
frame be raised to its upper limit position in order to disengage
the locking element 9, and allow the frame to be moved downwardly.
On the other hand, raising the U-shaped frame by means of the
handle 10 can be carried out to achieve any desired angular
position within the range.
[0014] In conclusion, and by way of summary, a conventional crib is
provided with projecting pins of the like to support a conventional
frame/spring structure of the type normally provided to receive a
crib mattress. The present invention provides a replacement frame
which includes recesses as shown at 11,11 to so receive such pins
(not shown) as are normally provided in a conventional crib
structure. It is a further feature of the present invention that
the preferred construction material from which the panels are made
is of plywood, in which case openings 4, might be provided as
desired to lighten the overall structure, and to provide
ventilation to the underside of a mattress placed on the frame
panels of the present invention.
[0015] It is also possible to make the frame of the present
invention from wood also. However, where desired, a metal frame
might be adapted for use with panels of the time described in the
proceeding paragraph.
[0016] Alternatively, the panels provided with a metal frame might
be fabricated from a suitable synthetic polymeric material.
Further, these panels might also comprise a combination of
conventional flexible steel straps and/or springs as used in
conventional one level mattress support structures generally.
