Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a mattress assembly. In
particular, the present invention relates to a mattress assembly
using a covering to cover a bed base, an air supply device, and a
mattress. Thus, the mattress assembly can be detached for cleaning
and can supply air for dissipating heat.
[0003] 2. Description of the Related Art
[0004] A typical mattress assembly comprises a covering with
springs mounted therein and a bed base. It is not uncommon that
drinks splash the covering or a child might pit on the covering.
But the conventional mattress assembly could not be detached for
cleaning the bed base and the covering. As a result, the bed base
and the covering would moisture and thus mold, which would lead to
growth of bacteria. Further, the conventional mattress assembly
could not provide the back of a user with required
ventilation/heat-dissipation if the user is suffering from
eczema.
[0005] FIG. 1 of the drawings illustrates a conventional mattress
assembly comprising a base 91, a cushioning layer 92, a latex layer
93, and a surface layer 94 sequentially superimposed on one
another. The cushioning layer 92 is made of foam material having a
high permeability and a low density. A face of the cushioning layer
92 contacting the base 91 includes a plurality of transverse
grooves 921. The latex layer 93 comprises a plurality of latex
strips 931 and separation plates 933. Rhombic vents 932 are defined
in each latex strop 931. Two adjacent ones of the latex strips 931
is separated by a separation plate 933 that includes openings 934
alternately disposed on two sides of the separation plate 933, each
opening 934 being hexagonal. The surface layer 94 is mounted on top
of the latex layer 93. When the latex layer 93 is pressed, the
vents 932 shrink while the cushioning layer 92 moves downward. The
air generated as a result of shrinkage of the rhombic vents 932 and
of downward movement of the cushioning layer 92 exits through the
separation plates 933. However, when liquid permeates the latex
layer 93, detachment of the mattress assembly for subsequent
cleaning or laundry is not easy. The liquid residing in the
separation plates 933 would stink and mold as a result of moisture.
Further, the back of a user lying on the mattress assembly could
not obtain a good ventilating effect.
[0006] FIG. 2 illustrates another conventional mattress assembly
comprising a fixed mattress 95, an air supply pipe 96, and a
plurality of ventilating pipes 97. The fixed mattress 95 includes a
head side 951 and a leg side 952. The air supply pipe 96 extends
through the head side 951 for supplying air into the ventilating
pipes 97 that are mounted between the head side 951 and the leg
side 952. The ventilating pipes 97 include a plurality of vents 971
through which air exits. The leg side 952 may prevent leakage of
the air. Although a ventilating/heat-dissipation effect is
obtained, the problem of permeation of liquid still exists. Namely,
the mattress assembly would mold as a result of permeation of
liquid. Detachment of the air supply pipe 96 is not easy. The
residing liquid would still stink even if the fixed mattress is
cleaned.
SUMMARY OF THE INVENTION
[0007] It is the primary object of the present invention to provide
a mattress assembly that is hygienic and friendly to environment.
The mattress assembly includes a mattress with vents, a bed base
with grooves for draining liquid, and a covering that can be easily
detached for subsequent cleaning of the mattress and the bed
base.
[0008] It is the primary object of the present invention to provide
a mattress assembly that includes an air supply device mounted
between the bed base and the mattress. Air from the air supply
device flows through the vents of the mattress for
ventilation/heat-dissipation purpose.
[0009] In accordance with the present invention, the mattress
assembly comprises a covering, a mattress, and a bed base. The
covering includes a cloth covering with a zipper to allow easy
opening/closing of the cloth covering. The mattress and the bed
base are covered by the cloth covering. The mattress includes a
plurality of vents communicated between the covering and the bed
base. The bed base includes a plurality of grooves in an upper side
thereof. When liquid permeates the covering, it passes through the
vents and then accumulates in the grooves. The mattress assembly
further includes an air supply device comprising a plurality of air
supply tubes and a plurality of ventilating tubes extending in the
grooves of the bed base. Air feeding from the air supply tubes
flows through the grooves of the bed base via the ventilating tubes
and then exit the vents of the mattress for circulation.
[0010] Other objects, specific advantages, and novel features of
the invention will become more apparent from the following detailed
description and preferable embodiments when taken in conjunction
with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] A preferred embodiment in accordance with the present
invention will now be described with reference to the accompanying
drawings.
[0017] Referring to FIG. 3, a mattress assembly 10 in accordance
with the present invention generally includes a covering 2, a
mattress 3, a bed base 4, and an air supply device 5. The covering
2 includes a cloth covering 22 with a zipper 21 for opening/closing
the covering 2 that houses the mattress 3, the bed base 4, and the
air supply device 5. In use, the mattress 10 is placed on an upper
side of a base 1. The mattress 3 includes a plurality of vents 31.
An upper side of the bed base 4 includes a plurality of transverse
grooves 41. The air supply device 5 is mounted to the bed base 4
for supply air into the transverse grooves 41. Thus, air is forced
to pass through the transverse grooves 41 and exits the mattress 3
via the vents 31 for ventilation. A cabinet 6 is provided adjacent
to the base 1 and the mattress 10 for mounting the air supply
device 5.
[0018] Referring to FIGS. 3 and 4, the air supply device 5 extends
between the mattress 3 and the bed base 4 for supplying air into an
interior of the mattress 3 for circulation. The air supply device 5
includes a power switch 51, a pump 52, a plurality of soft air
supply tubes 53, and a plurality of soft ventilating tubes 54. The
power switch 51 controls on/off of the pump 52 for feeding air. The
soft air supply tubes 53 are communicated with the pump 52 and
extend across the bed base 4. The soft ventilating tubes 54 are
communicated with the soft air supply tubes 53 and extend in the
transverse grooves 41.
[0019] Referring to FIGS. 4 and 5, when the pump 52 feeds air, the
air from the soft air supply tubes 53 flows through the transverse
grooves 41 via the soft ventilating tubes 54. Then, the air flows
upward and exits the mattress 3 through the vents 31. Thus, the
mattress assembly in accordance with the present invention provides
a ventilating effect as well as a heat-dissipating effect.
[0020] Referring to FIG. 3, the zipper 21 of the covering 2 may be
opened for removal of the mattress 3 and the bed base 4. Further, a
thick quilt may be placed into the cloth covering 22 for winter
use. Alternatively, a thin lining sheet may be placed into the
cloth covering 22 for summer use. The cloth covering 22 is made of
cotton, and the zipper 21 allows opening/closing of the cloth
covering 22 and allows easy attachment for laundry or other
cleaning.
[0021] Referring to FIG. 3, the mattress assembly in accordance
with the present invention allows easy cleaning of the mattress 3
and the bed base 4 by means of covering the mattress 3 and the bed
base 4 with a covering 2. The mattress 3 provides vents 31 arranged
in a matrix, and the bed base 4 provides transverse grooves 41 in
the upper side thereof. In a case that permeation of liquid occurs,
such as urine or drinks, the liquid may be accumulated in the
transverse grooves 41 and may drain through ends 411 of the
transverse grooves 411. Thus, the liquid would not permeate
interiors of the mattress 3 and the bed base 4. Namely, the liquid
would flow through the vents 31 to the bed base 4 and then drained
through the ends 411 of the transverse grooves 41. All the user has
to do is to detach the covering 2 from the mattress assembly 10 for
laundry and to clean the mattress 3 and the transverse grooves 41
of the bed base 4 by cloth or water. No liquid would reside inside
the mattress assembly 10. Thus, the mattress 3 and the bed base 4
in accordance with the present invention can be easily cleaned
without the risk of stinky odor.
[0022] The covering of the conventional mattress assembly of FIG. 1
cannot 41 be easily detached, and the surface layer 94 and the
latex layer 93 cannot be thoroughly cleaned such that the mattress
assembly would mold and stink as a result of moisture. Although the
conventional mattress assembly of FIG. 2 provides ventilating pipes
97 for ventilation and heat-dissipation, the ventilating pipes 97
are fixed to the fixed mattress 95 thus could not be easily
detached. As a result, cleaning would not be easy.
[0023] By contrast, the cloth covering 22 of the mattress assembly
in accordance with the present invention has a zipper 21 to allow
easy removal of the mattress 3 and the bed base 4. In a case that
liquid permeates the mattress 3 and the bed base 4 through the
cloth covering 22, the cloth covering 22 can be easily detached for
laundry. Neither the liquid nor the stinky odor resides. The
mattress 3 and the bed base 4 are made of latex or polyethylene and
are thus soft, resilient, not easy to deform, and friendly to
environment. In addition, vents 31 are provided in the mattress 3
and transverse grooves 41 are defined in the upper side of the bed
base 4. Thus, the liquid would not permeate the mattress 3 and the
bed base 4. The 1 mattress 3 and the bed base 4 can be cleaned as
soon as the covering 2 is removed. Further, the mattress assembly
in accordance with the present invention includes an air supply
device 5 comprising air supply tubes 53 and ventilating tubes 54
for supplying air into an interior of the mattress assembly 10,
thereby providing a ventilation/heat-dissipation effect. Further,
hot air may be provided through the air supply tubes 53 and the
ventilating tubes 54 for keeping the user warm when in winter.
[0024] Although the invention has been explained in relation to its
preferred embodiment as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the invention. It is,
therefore, contemplated that the appended claims will cover such
modifications and variations that fall within the true scope of the
invention.
