Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a mattress and, more
particularly, to a ventilation mattress, which uses an electric fan
to provide currents of air through air vents in the top layer of
the outer covering for ventilation. The ventilation mattress can be
made in any of a variety of forms for use as a seat mattress, sofa
mattress, or bed mattress.
[0003] 2. Description of the Related Art
[0004] Straws and bamboo strips are commonly used for making
cooling mattresses. Lying or sitting on a cooling mattress during a
hot weather is comfortable at the initial stage. However, the
cooling effect of a cooling mattress is gradually reduced with the
time in which the user sits or lies on the cooling mattress.
[0005] There are also known seat and bed mattresses formed of
strings of ball or block elements. These seat and bed mattresses
have open spaces in between the ball or block elements for
ventilation. However, when sitting or lying on a seat or bed
mattress of this design, the user's body will block the open
spaces, and the seat or bed mattress become hot within a short
time.
[0006] In order to eliminate the aforesaid drawbacks, a seat
mattress with enforced currents of air is developed. A seat
mattress of this design comprises a hard inner layer, a breathing
leather covering covered the hard inner layer, and an electric fan.
The hard inner layer has air guide grooves adapted to guide air in
a particular direction. The leather covering has air holes for
exhaust of air. The electric fan is controlled to induce currents
of air into the inside of the seat mattress. This design of seat
mattress still has drawbacks. Because currents of air are guided in
a particular direction, the ventilation effect is limited. Further,
because the inner layer is a hard member, it is not comfortable to
sit on the seat mattress.
SUMMARY OF THE INVENTION
[0007] The present invention has been accomplished under the
circumstances in view. It is the main object of the present
invention to provide ventilation mattress, which provides a
ventilation effect. It is another object of the present invention
to provide a ventilation mattress, which is high compressible. It
is still another object of the present invention to provide a
ventilation mattress, which can be conveniently adjusted to provide
hot air when cold, or cold air when hot. According to one aspect of
the present invention, the ventilation mattress comprises an outer
bag, the outer bag comprising a top fabric sheet layer, a bottom
fabric sheet layer peripherally sealed to the top fabric sheet
layer, at least one air inlet respectively extended out of the top
fabric sheet layer and the bottom fabric sheet layer, and a
plurality of air vents formed in the top fabric sheet layer in
communication with the at least one air inlet; at least one
flexible tube respectively connected to the at least one air inlet
of the outer bag; at least one electric fan respectively installed
in the at least one flexible tube and adapted to induce currents of
air into the inside of the outer bag; and a fabric stuffing member
stuffed in the outer bag between the top fabric sheet layer and the
bottom fabric sheet layer, the fabric stuffing member being formed
of interwoven nylon fibers and having open spaces for circulation
of air through the at least one air inlet and the air vents.
According to another aspect of the present invention, electric
cooling fans or electric fans with electric heater means may be
alternatively used subject to the condition of the weather.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0020] Referring to FIGS. 1.about.3, a ventilation mattress 1 is
shown comprising an outer bag 11, a fabric stuffing member 13 put
in the outer bag 11, an air inlet 12 formed in one side of the
outer bag 11, a flexible tube 14 extended from the air inlet 12,
and a high-performance fan 15 provided at one end of the flexible
tube 14 remote from the air inlet 12. The fabric stuffing member 13
is formed of interwoven nylon fibers 132, having open spaces 1321
in it. The outer bag 11 is formed of top and bottom fabric sheet
layers 131, having small air vents 111 in the top side (top fabric
sheet layer). The fan 15 comprises an air output port 151 connected
to the flexible tube 14, an air input port 152 in communication
with the air output port 151, a grille 153 covering the air input
port 152, an air filter 1531 mounted in the grille 153, a battery
chamber 155, a set of battery cells 1551 mounted in the battery
chamber 155, a battery lid 1552 covering the battery chamber 155,
and a power cord 154 for connection to an electric socket to obtain
the necessary working voltage. The fan 15 can obtain the necessary
working voltage either from the set of battery cells 1551, or city
power supply via the power cord 154. When starting the fan 15,
electric currents are caused to flow from the air output port 151
into the air inlet 12 and then the open spaces 321 in the fabric
stuffing member 13, and then to flow out of the outer bag 11
through the air vents 111.
[0021] Referring to FIG. 4, the ventilation mattress 1 can be made
having a plurality of air inlets 12, a plurality of flexible tubes
14 respectively extended from the air inlets 12, and a plurality of
high-performance fans 15 respectively fastened to the flexible
tubes 14. Each fan 15 has a plurality of mounting holes 156 for
fastening to a fixed place with screws 1561.
[0022] Referring to FIGS. 5 and 6, the ventilation mattress 1 can
be made to fit a sofa 2.
[0023] Referring to FIGS. 7 and 8, a double-sided adhesive tape 157
(see FIG. 7), or hook and loop materials 158 (see FIG. 8) may be
used to fix each fan 15 to a fixed place instead of the aforesaid
mounting holes 156 and screws 1561.
[0024] Referring to FIGS. 9 and 10 show an alternate form of the
present invention. According to this embodiment, the ventilation
mattress 3 comprises an outer bag 31 having air vents 311, a fabric
stuffing member 13 put in the outer bag 31, an air inlet 32 formed
in one side of the outer bag 31, a flexible tube 14 connected to
the air inlet 32, and a high-performance fan 15 provided at one end
of the flexible tube 14 remove from the air inlet 22. The fan 15 is
similar to the embodiment shown in FIGS. 1.about.8 with the
exception of the added electric power cord 1541, which is
connectable to the socket for cigarette lighter in a motor vehicle.
This embodiment of ventilation mattress 3 is suitable for mounting
on a chair 4.
[0025] FIG. 11 shows still another alternate form of the present
invention. According to this embodiment, the ventilation mattress 5
is designed for mounting on a rack for bed 6. The ventilation
mattress 5 has air vents 511 in the outer bag 51. After the
ventilation mattress 5 has been put on the rack for bed 6, the fans
15 of the ventilation mattress 5 are fixedly fastened to the rack
for bed 6 to secure the ventilation mattress 5 in place. When the
fan 15 started, induced currents of air are evenly distributed
through the fabric stuffing member 13 and the air vents 511.
Therefore, the user lying on the ventilation mattress 5 feel
comfortable.
[0026] Referring to FIG. 12, the ventilation mattress may be
directly formed integral with a sofa 2. According to this
embodiment, the fabric stuffing member 13 is put in between a
lining 21 and a outer covering 22 of the sofa 2. The outer covering
22 of the sofa 2 has air vents 23. When the fans 15 started,
induced currents of air flow through the open spaces in the fabric
stuffing member 13 to the outside of the sofa 2 via the air vents
23 of the outer covering 22.
[0027] A prototype of ventilation mattress has been constructed
with the features of FIGS. 1.about.12. The ventilation mattress
functions smoothly to provide all of the features discussed
earlier.
[0028] Although particular embodiments of the invention have been
described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the invention. For example, the fans used
can be cooling fans for use in hot weather, or fans with electric
heater means for use in cold weather. Accordingly, the invention is
not to be limited except as by the appended claims.
