Description
RELATED APPLICATIONS
[0001] This application claims the benefit under 35 U.S.C. 119(e)
of U.S. Provisional Patent Application Ser. No. 61/744,329, filed
Sep. 24, 2012; and U.S. Provisional Patent Application Ser. No.
61/795,538, filed Oct. 19, 2012, both of which are hereby
incorporated by reference.
SCOPE OF THE INVENTION
[0002] The present invention relates to a sleeping system for
providing a support surface for at least one person. In particular,
the invention provides a bed assembly that includes a number of
discrete mattress segment members that are insertable into a
support frame and which allows a user or manufacturer to customize
individual areas of the support surface to vary one or more of
softness, materials, compressibility, and thickness. Such mattress
segment members can be easily reorganized and replaced as
desired.
SUMMARY OF THE INVENTION
[0003] An object of the present invention is to provide a support
surface comprising a number of discrete mattress segment members
that can be replaced as desired. In one preferred embodiment, the
mattress segment members are substantially modular in design so as
to be interchangeable. Optionally, the mattress segment members can
be of variable firmness, such that the firmness of each area of the
support surface can be selected independently of the firmness of
the other areas. This allows a user to select a support surface
that provides their preferred firmness and comfort. In embodiments
of the invention where the support surface can accommodate two
persons, each person is able to select a desired firmness
independently of the other person.
[0004] In another preferred application, the bed assembly of the
invention can be used to treat patients for whom a more or less
rigid support surface is desired. A good sleeping surface should
provide support for the natural curves and alignment of the spine.
Experts say that the specific type and firmness level of a sleeping
surface that will provide the greatest comfort varies from person
to person. In general, experts agree that a sleeping surface should
allow the spine to assume the same natural curve when a person is
lying down as when that person is standing. A sleeping surface that
is too hard will force the spine into an unnatural position, while
one that is too soft will sag and fail to provide adequate
support.
[0005] Accordingly, further preferred embodiments of the bed
assembly of the present invention may be beneficial to health, and
may be useful in home and/or clinical cases where one desires to
correct defects in the vertebral column acquired through prolonged
use of too soft or too hard sleeping surfaces. In non-limiting
preferred constructions, the bed assembly of the present invention
is designed to allow a person to select a desired sleeping surface
support profile which may help to prevent ailments of the spine
that are caused by undesirable sleeping surfaces from originating
or becoming aggravated.
[0006] In one non-limiting preferred construction, a firmness
profile of the support surface is selected in consultation with a
doctor, chiropractor, physiotherapist, or other qualified health
professional. The firmness profile is preferably selected in view
of the unique shape and sleep requirements of the user. For
example, the optimal firmness profile may depend on the sleeping
style of the user, such as whether the user tends to sleep on his
or her front, back, or side. Furthermore, the height, weight, and
physical conditioning of the user may be relevant factors in
selecting the optimal firmness profile. A firmness profile that is
selected according to an individual's specific needs may help to
provide a more restful and comfortable sleep.
[0007] In another non-limiting preferred construction, the firmness
profile of the sleeping surface is selected to provide optimal
spinal alignment to a user while sleeping or resting. In
particular, the firmness profile is preferably selected to provide
the optimal support to each region of the user's spinal column,
including the cervical curve, the thoracic curve, the lumbar curve,
and the sacral curve. Achieving such an optimal firmness profile
may, in some cases, be useful in ameliorating and/or preventing
back pain.
[0008] In one possible hospital or institutional use, individual
mattress segment members that become contaminated with blood or
other fluids, for example, can be easily replaced without requiring
the entire support surface to be replaced. These individual
mattress segment members can then be washed and/or sterilized and
reused, or disposed of as required.
[0009] In an optional embodiment, the bed assembly is equipped with
a cover that can be removed and washed or replaced, and a filter
that is dust mite resistant and will not support mildew or
bacteria.
[0010] Another object of the present invention is to provide a bed
assembly with structural flexibility which, in preferred
embodiments, is capable of allowing a person to adjust a sleeping
surface to the desired comfort without interfering with the comfort
selected by a bed mate.
[0011] To achieve at least some of the foregoing objects, the
present invention provides a bed assembly comprising a frame and a
mattress member array, the mattress member array including a
plurality of mattress segment members, panels, or blocks, and the
frame having a plurality of upwardly opening support sockets,
recesses, cavities, or the like. Each of the support sockets is
shaped and sized to mateably receive the lower portion of an
associated one of said mattress segment members therein, such that
a support surface for at least one person is formed when each of
the support sockets holds one associated mattress member therein.
The number, size and shape of the support sockets can vary from one
bed assembly to another. These can be varied, for example,
depending on the size of the support surface, or the desired
comfort of a person using the support surface. The mattress segment
members can be made of variable materials and densities as desired.
Although not essential, each of the mattress segment members is
provided with a modular design of similar shape and size so as to
be interchangeable. In addition, each of the mattress segment
members optionally has a related pre-selected degree of firmness.
Preferably, not all of the mattress segment members in the mattress
member array have the same degree of firmness. By mix and matching
mattress segment members with support sockets, many different
support surfaces can be provided, with different firmness profiles.
This allows the user or users of the bed assembly to select the
desired support profile. For example, in a hospital setting the
support surface could be selected to accommodate the particular
needs and comfort preferences of a first patient. When this first
patient leaves the hospital, the support surface can be easily
modified to select a firmness profile as required or preferred by a
second patient. Furthermore, should one of the mattress segment
members become contaminated with body fluids, such as blood, the
contaminated mattress segment member can be easily replaced,
without having to replace the entire support surface.
[0012] In optional constructions, the support surface can
accommodate more than one person, preferably two persons. The
support surface may include two support regions for supporting the
two persons, each support region having a firmness profile.
Preferably, the firmness profile of each support region can be
selected independently of the firmness profile selected for the
other support region. This allows a first user of the support
surface to select their desired firmness profile without
interfering with the preferred firmness profile of the second user
of the support surface.
[0013] In one construction, the support surface formed by the
mattress segment members held in the support sockets produces an
irregular top surface, with gaps between the mattress segment
members where the sidewalls of the support sockets are located.
Although not essential, the bed assembly further includes a comfort
panel that is sized and shaped to substantially cover the support
surface, and which provides a substantially uniform top surface
when placed thereon. The comfort panel may be of variable
thickness.
[0014] In one embodiment the mattress segment members are held in
the support sockets by gravity. Alternatively, the mattress segment
members may be held in the support sockets solely or additionally
by friction, or by a physical connection such as a fastener, clip,
hook and loop connector or otherwise.
[0015] Each of the mattress segment members preferably have unique
color coding, with the color of the mattress segment member
indicating its related degree of firmness. This feature allows for
the bed assembly to be very quickly adapted to the desired firmness
profile, as the related degree of firmness of each mattress segment
member can be very quickly identified.
[0016] In one construction, the bed assembly of the invention may
be completely disassembled into its component parts, and rebuilt as
desired.
[0017] The bed assembly of the present invention is, in one
non-limiting construction, for use in a hospital. In a hospital
setting, the filter can protect the sleeping surface from
contamination with body fluids, mildew, bacteria, parasites or
other contaminants. Furthermore, the interchangeable mattress
segment members allow individual mattress segment members to be
replaced when contaminated with, for example, body fluids, without
requiring an entire mattress to be replaced. Furthermore, the
support surface can be readily adapted to different preferred
firmness profiles dependant upon the patient who is using the
support surface at any given time.
[0018] Although not essential, the bed assembly may include more
mattress segment members then there are support sockets. The extra
mattress segment members allow for greater flexibility in selecting
the desired sleeping surface, such that the firmness selected for
each section of the sleeping surface can be selected independently
of the firmness selected for each other section of the sleeping
surface.
[0019] Accordingly, in one aspect the present invention resides in
a bed assembly, comprising a frame and a mattress member array;
said mattress member array comprising a plurality of discrete
mattress segment members, each of the mattress segment members

comprises a frame 22 and a mattress member array 24. The mattress
member array 24 comprises a plurality of discrete mattress segment
members 26.
[0055] As best shown in FIGS. 3 and 4, the mattress segment members
26 are generally rectangular six sided foam blocks, each with an
upper portion 28 having an upper surface 30, and a lower portion 32
having a lower surface 34. Each mattress segment member 26 has a
height 36, a width 38, and a length 40. The mattress segment
members 26 are resiliently compressible, with each having an
uncompressed height 36u when in an uncompressed state I, and a
compressed height 36c when in a substantially compressed state II.
Each of the mattress segment members 26 are of substantially the
same size and shape so as to be interchangeable. Preferably, the
height 36 of the mattress segment members 26 is in the range of 10
cm to 50 cm; the width 38 of the mattress segment members 26 is in
the range of 30 cm to 110 cm; and the length 40 of the mattress
segment members 26 is in the range of 30 cm to 55 cm. More
preferably, the height 36 of the mattress segment members 26 is in
the range of 15 cm to 40 cm; the width 38 of the mattress segment
members 26 is in the range of 45 cm to 100 cm; and the length 40 of
the mattress segment members 26 is in the range of 45 cm to 55
cm.
[0056] The mattress segment members 26 in the mattress member array
24 do not all have the same degree of firmness. Although the
mattress member array 24 may include mattress segment members 26
with any desired number of degrees of firmness to choose from,
preferably there are at least five different degrees of firmness
(for example, gentle support, medium support, medium firm support,
firm support, and extra firm support). As will be described, this
feature allows a user or manufacturer to customize the bed assembly
10 to provide the desired comfort and support. As shown in FIG. 4,
the mattress segment member 26.1 has a first color 42, and the
mattress segment member 26.2 has a second color 44. The first color
42 indicates that mattress segment member 26.1 has a first degree
of firmness, and the second color 44 indicates that the mattress
segment member 26.2 has a second degree of firmness. This color
coding allows the firmness of a mattress segment member 26 to be
ascertained quickly and easily.
[0057] As shown in FIG. 3, the frame 22 is provided as a wooden
support structure comprising a mattress member receptacle 46 and a
base 48. The base 48 is positioned below and supporting the
mattress member receptacle 46. The base 48 and the mattress member
receptacle 46 meet at contact point 50 and are tightly joined to
each other to form one stable unit. The mattress member receptacle
46 defines a number of upwardly opening support sockets 52 having
generally vertical sidewalls 54 and a closed bottom 56. The support
sockets 52 each have a width 58 and a length 60. Each sidewall 54
has a height 62 and an uppermost edge 64 (best shown in FIG.
7A).
[0058] The support sockets 52 are sized and shaped to each mateably
receive the lower portion 32 of a mattress segment member 26
therein. The width 58 and length 60 of the support sockets 52 are
selected to substantially correspond to the width 38 and length 40
of the mattress segment members 26. This allows the support sockets
52 to each securely accommodate a mattress segment member 26
therein. Preferably, the width 58 of the support sockets 52 is in
the range of 30 cm to 110 cm; and the length 60 of the support
sockets 52 is in the range of 30 cm to 55 cm. More preferably, the
width 58 of the support sockets 52 is in the range of 45 cm to 100
cm; and the length 60 of the support sockets 52 is in the range of
45 cm to 55 cm.
[0059] The sidewalls 54 are designed to hold the mattress segment
members 26 in place, and prevent them from shifting while the bed
assembly 10 is in use. The height 62 of the sidewalls 54 is
selected to be lower than the compressed height 36c of the mattress
segment members 26. As will be described, this allows for a more
comfortable sleep by ensuring that the weight of a person lying on
the bed assembly 10 is supported by the resiliently compressible
mattress segment members 26, rather than the hard, wooden sidewalls
54. The height 62 of the sidewalls 54 is preferably in the range of
8 cm to 48 cm. More preferably, the height 62 of the sidewalls 54
is in the range of 13 cm to 38 cm.
[0060] As shown by the arrows in FIG. 3, the mattress segment
members 26a-h are to be received by the support sockets 52a-h,
respectively. However, as each of the mattress segment members 26
are of substantially the same size and shape, it is possible for
any mattress segment member 26 to be received by any support socket
52.
[0061] When the lower portion 32 of a mattress segment member 26 is
received by a support socket 52, the upper surface 30 of the
mattress segment member 26 sits above the uppermost edge 64 of the
sidewalls 54 (best shown in FIG. 7A). A support surface 66 for
supporting two people is formed when a mattress segment member 26
is held in each of the support sockets 52 of the mattress member
receptacle 46 (best shown in FIG. 5). Having the upper surface 30
of the mattress segment members 26 above the uppermost edge 64 of
the sidewalls 54 ensures that the weight of a person laying on the
support surface 66 is supported by the resiliently compressible
mattress segment members 26, and not the hard, wooden sidewalls 54.
This allows for a more comfortable sleep.
[0062] The support surface 66 has a length 68 and a width 70.
Preferably, the support surface 66 has a length 68 in the range of
135 cm to 215 cm; and a width 70 in the range of 65 cm to 210 cm.
More preferably, the support surface 66 has a length 68 in the
range of 190 cm to 205 cm; and a width 70 in the range of 95 cm to
190 cm.
[0063] As is best shown in FIG. 5, the support surface 66 includes
two support regions 72, each sized to accommodate one person laying
thereon. Each of the support regions 72 comprises four mattress
segment members 26 placed within four support sockets 52. Each
support region 72 has a firmness profile that is dependent on the
degree of firmness of each of the mattress segment members 26 in
the support region 72. For example, the firmness profile of the
support region 72a shown in FIG. 5 is determined by the degree of
firmness of each of the mattress segment members 26a-d held in
support sockets 52a-d. As will be described, the features of the
bed assembly 10 allow the firmness profile of each support region
72 to be selected independently.
[0064] The mattress support subassembly 14 is designed to allow the
users of the bed assembly 10 to select a support surface 66 with
their desired level of support and comfort. By selecting mattress
segment members 26 with the desired degree of firmness, the users
of the bed assembly 10 can design and create an individualized
support surface 66. For example, a user may wish to have a sleeping
surface 66 that supports the head with a mattress segment member 26
of one degree of firmness, and supports the rest of the body with
mattress segment members 26 of another degree of firmness.
[0065] Furthermore, if the user of the bed assembly 10 wants to try
a different configuration of mattress segment members 26, the
mattress segment members 26 can be easily reorganized as desired.
Because the mattress segment members 26 are interchangeable, the
mattress segment members 26 in one support socket 52 can be easily
swapped with a mattress segment member 26 in another support socket
52. Furthermore, as the mattress segment members 26 are color
coded, the degree of firmness of each can be ascertained quickly
and easily, facilitating the process of designing, creating, and
reorganizing the desired support surface 66.
[0066] Preferably, the mattress member array 24 includes more
mattress segment members 26 than there are support sockets 52 in
the mattress member receptacle 46. More preferably, the mattress
member array 24 includes at least as many mattress segment members
26 of each degree of firmness as there are support sockets 52 in
the mattress member receptacle 46. This allows for greater
customizability, as the degree of firmness of the mattress segment
member 26 in each support socket 52 can be selected independently
of the degree of firmness of the mattress segment members 26 in the
other support sockets 52. This would allow the two people using the
mattress support subassembly 14 shown in FIG. 5 to each select
their desired firmness profile for their respective support regions
72 independently of each other. In this way, the present invention
allows two people with different needs and/or preferences with
respect to bed comfort and support to share the bed assembly 10,
while still getting their desired comfort and support.
[0067] In an optional application, the bed assembly 10 is for use
in a hospital. The mattress support subassembly 14 is particularly
advantageous in the hospital setting, in that the individual
mattress segment members 26 can be easily removed, washed,
replaced, or disposed of as required. In a hospital setting, body
fluids such as blood can frequently come in contact with hospital
beds. When a standard mattress becomes contaminated with blood, the
entire mattress may need to be removed and replaced, even if only a
small area of the mattress is affected. It may also be difficult to
clean a standard mattress, as they are generally large in size and
cannot be accommodated by smaller cleaning machines. In contrast,
in the bed assembly 10 of the present invention, only the
individual mattress segment members 26 that become contaminated
with blood need to be removed. These can then be easily replaced
with individual mattress segment members 26, without requiring all
of the mattress segment members 26 to be replaced. Furthermore, as
the mattress segment members 26 are of smaller size than a standard
mattress, they are much more easily accommodated by smaller
cleaning machines, such as standard washing machines for bedding
and clothing.
[0068] In the course of a year, a hospital bed is typically used by
many different patients, each having their own requirements and
preferences with respect to support and comfort. A standard
mattress cannot be customized to accommodate these differing needs.
The bed assembly 10 of the present invention, however, can be
easily customized to provide the support surface 66 required by
each patient. Furthermore, using the color coding, hospital staff
can easily and quickly re-organize the mattress support subassembly
14 to the preferences of new patients.
[0069] FIG. 5 best shows a partially exploded view of the mattress
support subassembly 14 and the comfort panel 16. The comfort panel
16 is a generally rectangular, resiliently compressible foam pad.
The comfort panel 16 has a length 74, a width 76, and a thickness
78. The length 74 and width 76 of the comfort panel 16 are selected
to generally correspond to the length 68 and width 70 of the
support surface 66, such that the comfort panel 16 substantially
covers the support surface 66 when placed thereon. Preferably, the
comfort panel 16 has a length 74 in the range of 135 cm to 215 cm;
and a width 76 in the range of 65 cm to 210 cm. More preferably,
the comfort panel 16 has a length 74 in the range of 190 cm to 205
cm; and a width 76 in the range of 95 cm to 190 cm.
[0070] FIG. 6 best shows the mattress support subassembly 14 with
the comfort panel 16 in place above the support surface 66. The
comfort panel 16 allows for a more comfortable sleep by providing
an extra layer of cushion on top of the mattress segment members
26. The thickness 78 of the comfort panel 16 is selected to achieve
the desired comfort. Preferably, the thickness 78 of the comfort
panel 16 is in the range of 1 cm to 10 cm. More preferably, the
thickness 78 of the comfort panel 16 is in the range of 2 cm to 6
cm.
[0071] FIG. 7A shows a cross-sectional view of the mattress support
subassembly 14 shown in FIG. 5, taken along the line 4-4'. As
shown, the upper surfaces 30 of the mattress segment members 26 are
above the uppermost edge 64 of the sidewalls 54. This produces gaps
the in support surface 66 above the sidewalls 54, and results in
the formation of an irregular top surface 80.
[0072] FIG. 7B shows a cross-sectional view of the mattress support
subassembly 14 and comfort panel 16 shown in FIG. 6, taken along
the line 6-6'. As shown, the comfort panel 16 covers the gaps in
the support surface 66, and produces a substantially uniform top
surface 82. The substantially uniform top surface 82 allows for a
more comfortable sleep, by providing a more even sleeping
surface.
[0073] The cover 20 is best shown in FIG. 1. The cover 20 is made
from a washable fabric and forms an outer layer of the bed assembly
10. The cover 20 bears the brunt of the wear and tear of the use of
the bed assembly 10, and can be removed, washed, and replaced as
required. As shown in FIG. 1, the cover 20 includes a bottom
section 84; a top section 86; and a top sheet 88. The bottom
section 84 defines a cavity that is sized and shaped to mateably
receive a lower portion 90 of the frame 22 therein. The top section
86 defines a cavity that is sized and shaped to mateably receive
the comfort panel 16, the support surface 66 and an upper portion
92 of the frame 22. A first zipper system 94 releasably connects
the bottom 84 and top 86 sections of the cover 20. When the bottom
84 and top 86 sections are mounted over the comfort panel 16 and
the mattress support subassembly 14 and are connected together with
the first zipper 94, the comfort panel 16 and the mattress support
subassembly 14 are completely encompassed by the cover 20 (best
shown in FIG. 2). When assembled in this way, the bottom 84 and top
86 sections hold the comfort panel 16 and the mattress support
subassembly 14 together in a secure fashion. This allows the bed
assembly 10 to be moved, for example, without various parts such as
the comfort panel 16 and the mattress segment members 26 falling
out of place. The top section 86 can be easily disconnected from
the bottom section 84 in order to access the comfort panel 16 and
the mattress support subassembly 14 and, for example, replace or
reorganize the mattress segment members 26.
[0074] FIG. 8 best shows the bed assembly 10 in a partially
assembled state, showing the placement of the filter panel 18 and
the top sheet 88. The top sheet 88 of the cover 20 is a rectangular
sheet that is sized and shaped so as to substantially cover an
uppermost surface 96 of the top section 86. The uppermost surface
96 is a relatively flat, rectangular surface that sits on top of
the comfort panel 16. The uppermost surface 96 has a length 98 and
a width 100 that are substantially equal to the length 74 and width
76 of the comfort panel 16, respectively. The top sheet 88 has a
length 102 and a width 104 that are slightly less than the length
98 and width 100 of the uppermost surface 98, respectively. The top
sheet 88 has a circumference 106, the entire circumference 106
being releasably connectable to the top section 88 with a second
zipper system 108. When the top sheet 88 is connected to the top
section 86, a filter compartment 110, sized and shaped to hold the
filter panel 18, is formed therebetween (best shown in FIG. 2).
[0075] FIG. 9 best shows the filter panel 18. The filter panel 18
has a length 112 and a width 114. The length 112 and width 114 of
the filter panel 18 are equal to, or slightly less than, the length
102 and width 104 of the top sheet 88, respectively. This allows
the filter panel 18 to sit securely below the top sheet 88 in the
filter compartment 110. The filter panel 18 is a thin, pliable
sheet that is dust mite resistant, and substantially impermeable to
body fluids, bacteria, and parasites. The filter panel 18 is
washable and reusable.
[0076] When the filter panel 18 is placed in the filter compartment
110, it helps to protect the comfort panel 16 and the mattress
support subassembly 14 from contamination with body fluids, such as
blood, as well as dust mites, parasites and bacteria. The top sheet
88 holds the filter panel 18 in place between a person lying on the
bed assembly 10 and the mattress support subassembly 14. If the top
sheet 88 and filter panel 18 become contaminated with blood, the
top sheet 88 can be easily disconnected from the top section 86,
and the top sheet 88 and filter panel 18 can be easily removed and
washed or replaced, without having to wash or replace all of the
cover 20. Furthermore, by protecting the comfort panel 16 and the
mattress support subassembly 14 from contamination, the filter
panel 18 reduces the frequency with which the comfort panel 16 and
the mattress segment members 26 need to be replaced and washed or
disposed of. This is particularly advantageous in the hospital
setting, as hospital beds may be frequently contaminated by body
fluids such as blood.
[0077] FIG. 10 best shows a cross-sectional view of a mattress
segment member 26 according to an alternate embodiment of the
invention. In this embodiment, the mattress segment member 26 has a
hollow spring core 116 comprising a plurality of resiliently
compressible springs or coils 118. The springs 118 are formed from
coiled metal strands. The type of metal and the shape and size of
the springs 118 are selected to provide the desired firmness and
support.
[0078] A first upholstery layer 120 sits immediately above the
spring core 116, and a second upholstery layer 122 sits immediately
below the spring core 116. The first 120 and second 122 upholstery
layers are made from a soft, resiliently compressible foam, and
provide a cushioning layer to give the mattress segment member 26
the desired comfort. The mattress segment member 26 can be placed
in a support socket 52 with either the first 120 or second 122
upholstery layer facing upwards. If the first upholstery layer 120
is placed facing upwards in the support socket 52, after prolonged
use it may lose some resiliency and comfort may decrease. The user
of the bed assembly 10 can then flip the mattress segment member 26
around so that the second upholstery layer 122 is facing upwards.
In this way, the useful life of the mattress segment member 26 can
be increased.
[0079] The first upholster layer 120 has a thickness 124, and the
second upholster layer 122 has a thickness 126. The thicknesses 124
and 126 are selected to provide the desired softness and comfort.
Optionally, the thicknesses 124 and 126 are different, such that
the comfort provided by the first 120 and second 122 upholstery
layers differs. This allows for greater customizability, as the
user of the bed assembly 10 can choose to use either the first 120
or second 122 upholstery layer in the support surface 66, according
to the user's preferences.
[0080] A pliable fabric casing 128 completely encompasses the
spring core 116 and the first 120 and second 122 upholstery layers.
The casing 128 helps to protect the spring core 116 and the first
120 and second 122 upholstery layers from damage by keeping them
unexposed. The casing 128 also provides a smooth outer surface to
the mattress segment member 26, easing the insertion and removal of
the mattress segment member 26 from the support sockets 52.
Optionally, the casing 128 is made from a material that is
impermeable to fluid. This is particularly advantageous in the
hospital setting, as it helps protect the spring core 116 and the
first 120 and second 122 upholstery layers from contamination with
body fluids, such as blood, and allows for easier cleaning of the
mattress segment member 26.
[0081] In a preferred embodiment, the arrangement of mattress
segment members 26 in the mattress support subassembly 14 is
selected in consultation with a doctor, chiropractor,
physiotherapist, or other qualified health professional. The
firmness profile of each support region 72 is preferably selected
in view of the unique shape and sleep requirements of the user of
that support region 72. Furthermore, the firmness profile of the
support region 72 is preferably selected to provide optimal spinal
alignment to the user while sleeping or resting.
[0082] FIG. 11 shows a human vertebral column 130. The vertebral
column 130 includes a number of distinct regions, including the
cervical curve 132, wherein the cervical vertebrae 134 are located;
the thoracic curve 136, wherein the thoracic vertebrae 138 are
located; the lumbar curve 140, wherein the lumbar vertebrae 142 are
located; and the sacral curve 144, wherein the sacrum 146 and
coccygeal vertebrae 148 are located. In a preferred embodiment, the
firmness profile of each support region 72 is selected to provide
the optimal support to each region of the vertebral column 130,
including the cervical curve 132, the thoracic curve 136, the
lumbar curve 140, and the sacral curve 144.
[0083] FIG. 12 shows a partial view of a preferred embodiment of
the bed assembly 10. In this embodiment, the support region 72
includes a mattress segment member 26 cc that is sized and arranged
specifically to provide support for the cervical curve 132, a
mattress segment member 26tc that is sized and arranged
specifically to provide support for the thoracic curve 136, a
mattress segment member 261c that is sized and arranged
specifically to provide support for the lumbar curve 140, and a
mattress segment member 26sc that is sized and arranged
specifically to provide support for the sacral curve 144.
Preferably, the related degree of firmness of each of the mattress
segment members 26 cc, 26tc, 261c, and 26sc is selected in
consultation with a doctor or chiropractor to provide the optimal
firmness and support for the corresponding regions of the vertebral
column 130. For example, the user may, in consultation with a
doctor or chiropractor, decide that the mattress segment member
261c should be selected so as to provide firm support to the lumbar
curve 140, while the cervical curve 132, thoracic curve 136, and
sacral curve 144 should each have medium firm support.
[0084] Achieving such optimal support for the vertebral column 130
through consultation with a qualified health professional may, in
some cases, be useful in ameliorating and/or preventing back pain.
The effect of the customized support region 72 on back pain and/or
alignment of the vertebral column 130 can be tracked over time, and
easily adjusted as necessary. Furthermore, in embodiments of the
bed assembly 10 wherein there is a separate support region 72 for
each of two different users, each support region 72 can be
independently customized so as to accommodate the needs of each
user.
[0085] Although the first 120 and second 122 upholstery layers have
been described as made from a foam material, the invention is not
so limited. The first 120 and second 122 upholstery layers could be
made from any suitable soft material, such as natural latex, wool,
hay, animal hair, cotton, and other synthetic and natural fibres.
Furthermore, the first 120 and second 122 upholstery layers can
each be made from a different material, or combination of
materials. This provides for even greater customizability, allowing
the user of the bed assembly 10 to create a support surface 66 that
uses whichever of the first 120 and second 122 upholstery layers
the user prefers.
[0086] Although the bed assembly 10 has been described as for use
in a hospital setting, it could be used in other environments as
well, such as a residential setting, a nursing home, a university
dormitory, or a military barracks. Various features of the bed
assembly 10 can be adapted or omitted, and other features can be
added, in order to best suit the environment in which the bed
assembly 10 is to be used. For example, in a residential setting in
which contamination with body fluids such as blood is less of a
concern, the filter panel 18 can be omitted.
[0087] While the mattress segment members 26 have been described as
made from either a foam material, or a spring core 116 with a
fabric casing 128 and first 120 and second 122 upholstery layers,
the invention is not so limited. The mattress segment members 26
could be made from any suitable materials for providing the desired
comfort and support. For example, the mattress segment members 26
could be made from natural latex and/or wool. Furthermore, the
mattress member array 24 could include mattress segment members 26
made with different materials and combinations of materials. The
upper surface 30 of the mattress segment members 26 could also have
contours or curves that provide added comfort or support to
selected parts of the body.
[0088] Though the mattress segment members 26 are of substantially
the same size and shape in the preferred embodiments described
above, this is not required. For example, the mattress member array
24 could include mattress segment members 26 of different sizes and
shapes, with particularly shaped mattress segment members 26
compatible with only some of the support sockets 52 in the mattress
member receptacle 46.
[0089] Although the frame 22 has been described as made from wood,
the frame 22 could be made from any suitable material that is
sufficiently solid to hold the mattress segment members 26 therein
and support the weight of the person or persons using the bed
assembly 10. For example, the frame 22 could be made from metal,
plastic, semi-soft foam materials, or combinations thereof.
[0090] While the mattress segment members 26 have been described in
the preferred embodiments as generally rectangular in shape, in an
alternate embodiment the mattress segment members 26 each have an
upper lip that is of greater width than the support sockets 52. The
upper lip sits on top of the sidewalls 54 of the support sockets 52
when a mattress segment member 26 is placed therein. In this
embodiment, the upper lips substantially fill the gaps which would
otherwise exist above the sidewalls 54 of the support sockets 52 so
as to provide a more uniform surface.
[0091] In a further alternate embodiment, the sidewalls 54 of the
support sockets 52 are formed of a semi-soft material. In this
embodiment, having some contact between the sleeping person and the
uppermost edge 64 of the sidewalls 54 does not substantially
interfere with the desired comfort of the support surface 66, as
the sidewalls 54 have some give. In this embodiment, the mattress
segment members 26 are able to sit lower in the support sockets 52
to create for a more uniform surface.
[0092] Although the support sockets 52 have been described in the
preferred embodiments as having a closed bottom 56, this feature is
not necessary. For example, the support sockets 52 could instead
have a bottom flange that leaves an opening at the bottom of the
support sockets 52. The size of this opening would be selected so
that the mattress segment members 26 could not pass through the
opening and would be held in place in the support sockets 52.
Alternatively, the support sockets 52 could have no bottom at all,
with the mattress segment members 26 resting directly on the base
48 below.
[0093] Though the frame 22 has been described in the preferred
embodiments as including a base 48, this feature is not strictly
necessary. Instead, the mattress member receptacle 46 could sit
directly on the floor. Alternatively, the bed assembly 10 of the
invention could be used in conjunction with a standard bed frame
with legs. In this embodiment, the bed assembly 10 would sit on top
of the standard bed frame, but the standard bed frame would not by
encompassed by the cover 20.
[0094] While the comfort panel 16 has been described in the
preferred embodiments as having a uniform thickness 78, this is not
necessary. A comfort panel 16 of variable thickness 78 could also
be used to achieve the desired comfort. The comfort panel 16 could
further be made from any suitable, resiliently compressible
material.
[0095] The bed assembly 10 has been depicted in the preferred
embodiments as shaped to provide a generally rectangular support
surface 66. Alternatively, the bed assembly 10 could be shaped to
provide a support surface 66 that is circular, square, oval, half
moon, or any other desired shaped. The support sockets 52 and
mattress segment members 26 could likewise be provided with
different shapes and sizes from those depicted in the preferred
embodiments.
[0096] Although the cover 20 has been described in the preferred
embodiments as using zipper connectors 94 and 108, this is not
required. Other connectors, such as hook and loop connectors,
clips, and ties could also be used.
[0097] The preferred embodiments illustrated and described are in
no way intended to limit the invention. Various modifications and
variations may be made thereto without departing from the scope of
the invention.
