7 assembly can be detached for cleaning and can supply air for dissipating
8 heat.
9 2.~'~,syntion of the Related Art
A typical mattress assembly comprises a covering with springs
11 mounted therein and a bed base. It is not uncommon that drinks splash the
12 covering or a child might pit on the covering. But the conventional
mattress
13 assembly could not be detached fox cleaning the bed base and the covering.
i4 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
16 assembly could not provide the back of a user with required
17 ventilation/heat-dissipation if the user is suffering from eczema.
18 Fig. 1 of the drawings illustrates a conventional mattress assembly
19 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
21 92 is made of foam material having a high permeability and a low density.
22 A face of the cushioning layer 92 contacting the base 91 includes a
plurality
23 of transverse grooves 921. The latex layer 93 comprises a plurality of
latex
24 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
26 separation plate 933 that includes openings 934 alternately disposed on two
r
CA 02384473 2004-11-08
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 stiplc 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.
Fig. 2 illustrates another conventional mattress assembly comprising
a fixed mattress 951 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.

9 Detailed Descrip ion of thg Preferred Embodiment
1 o A preferred embodiment in accordance with the present invention
1 i will now be described with reference to the accompanying drawings.
12 Referring to Fig. 3, a mattress assembly 10 in accbrdance with the
13 present invention generally includes a covering 2, a mattress 3, a bed base
4,
14 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
i6 3, the bed base 4, and the air supply device 5. In use, the mattress 10 is
17 placed on an upper side of a base L . The mattress 3 includes a plurality
of
18 vents 31. An upper side of the bed base 4 includes a plurality of
transverse
19 grooves 41. The air supply device 5 is mounted to the bed base 4 for supply
2o air into the transverse grooves 41. Thus, air is forced to pass through the
21 transverse grooves 41 and exits the mattress 3 via the vents 31 for
22 ventilation. A cabinet 6 is provided adjacent to the base 1 and the
mattress
23 10 for mounting the air supply device 5.
24 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
26 mattress 3 for circulation. The air supply device 5 includes a power switch
4
CA 02384473 2002-05-O1
1 S l, a pump 52, a plurality of soft air supply tubes 53, and a plurality of
soft
2 ventilating tubes 54. The power switch S 1 controls on/off of the pump 52
3 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
6 grooves 41.
Referring to Figs. 4 and 5, when the pump 52 feeds air, the air from
8 the soft air supply tubes 53 flows through the transverse grooves 41 via the
9 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
11 present invention provides a ventilating effect as well as a heat-
dissipating
12 effect.
13 Referring to Fig. 3, the zipper 21 of the covering 2 may be opened
14 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
16 lining sheet may be placed into the cloth covering 22 for summer use. The
17 cloth covering 22 is made of cotton, and the zipper 21 allows
18 opening/closing of the cloth covering 22 and allows easy attachment for
19 laundry or other cleaning.
Referring to Fig. 3, the mattress assembly in accordance with the
21 present invention allows easy cleaning of the mattress 3 and the bed base 4
22 by means of covering the mattress 3 and the bed base 4 with a covering 2.
23 The mattress 3 provides vents 31 arranged in a matrix, and the bed base 4
24 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
26 accumulated in the transverse grooves 41 and may drain through ends 411
s
CA 02384473 2002-05-O1
1 of the transverse grooves 411. Thus, the liquid would not permeate interiors
2 of the mattress 3 and the bed base 4. Namely, the liquid would flow through
3 the vents 31 to the bed base 4 and then drained through the ends 411 of the
4 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
6 the transverse grooves 41 of the bed base 4 by cloth or water. No liquid
7 would reside inside the mattress assembly 10. Thus, the mattress 3 and the
8 bed base 4 in accordance with the present invention can be easily cleaned
9 without the risk of stinky odor.
The covering of the conventianal mattress assembly of Fig. 1 cannot
11 be easily detached, and the surface layer 94 and the latex layer 93 cannot
be
12 thoroughly cleaned such that the mattress assembly would mold and stink
13 as a result of moisture. Although the conventional mattress assembly of
Fig.
14 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
16 easily detached. As a result, cleaning would not be easy.
17 By contrast, the cloth covering 22 of the mattress assembly in
18 accordance with the present invention has a zipper 21 to allow easy
19 removal of the mattress 3 and the bed base 4. In a case that liquid
2o permeates the mattress 3 and the bed base 4 through the cloth covering 22,
21 the cloth covering 22 can be easily detached for laundry. Neither the
liquid
22 nor the stinky odor resides. 'The mattress 3 and the bed base 4 are made of
23 latex or polyethylene and are thus soft, resilient, not easy to deform, and
24 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.
26 Thus, the liquid would not permeate the mattress 3 and the bed base 4. The
6
CA 02384473 2002-05-O1
1 mattress 3 and the bed base 4 can be cleaned as soon as the covering 2 is
2 removed. Further, the mattress assembly in accordance with the present
3 invention includes an air supply device 5 comprising air supply tubes 53
4 and ventilating tubes 54 for supplying air into an interior of the mattress
assembly 10, thereby providing a ventilation/heat-dissipation effect. Further,
6 hot air may be provided through the air supply tubes 53 and the ventilating
'7 tubes 54 for keeping the user warm when in winter.
8 Although the invention has been explained in relation to its preferred
9 embodiment as mentioned above, i.t is to be understood that many other
l0 possible modifications and variations can be made without departing from
11 the scope of the invention. It is, therefore, contemplated that the
appended
12 claims will cover such modifications and variations that fall within the
true
13 scope of the invention.
