DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 to 6, an air supply apparatus 1 in accordance with the
invention comprises the following components as discussed in detail below.
A transverse air bladder 10 is provided. A connection assembly 11
includes a first line 110, a second line 111, a third line 112 having one end
coupled to the other ends of the first and second lines 110 and 111, a fourth
line 113 having the other end coupled to the air bladder 10, a fifth line 114
having the other end coupled to the air bladder 10, and a sixth line 115
having
the other end coupled to the air bladder 10. An air compressor 12 includes a
3
CA 2972291 2017-06-30
first inlet 120 coupled to one end of the first line 110, and a second outlet
121
coupled to one end of the second line 111. A switch 13 is electrically
connected
to the air compressor 12 for controlling the activation of the air compressor
12.
A plurality of parallel straps 14 are provided on a top surface of a
rectangular
foundation 2. The air bladder 10 is inserted through gaps between the straps
14 and the top surface of the foundation 2 and fastened on the foundation 2 by
the elastic compression of the straps 14. The foundation 2 includes a
plurality
of transverse openings 20 for allowing the other ends of the fourth, the fifth
and
the sixth lines 113, 114 and 115 to pass through to couple to the air bladder
10.
The foundation 2 further comprises a lumbar zone 21, a head zone 22, and a
leg zone 23. A rectangular, inflated air mattress 3 is placed on the
foundation 2.
A female connector 116 is provided at the other end of the third line 112.
The female connector 116 includes a check valve 1160 communicating with
the third line 112. A male connector 117 is provided at one ends of the
fourth,
.. the fifth and the sixth lines 113, 114 and 115. The male connector 117
includes
a first port 1130 communicating with the fourth line 113, a second port 1140
communicating with the fifth line 114, and a third port 1150 communicating
with
the sixth line 115 respectively. The female connector 116 is inserted into the
male connector 117 to be connected together. The air bladder 10 can be
.. inflated by performing the steps of turning on the switch 13 to activate
the air
4
CA 29/2291 2017-06-30
compressor 12, and transporting pressurized air from the air compressor 12 to
the air bladder 10 via the first and second outlets 120 and 121, the first
line 110,
the third line 112, the check valve 1160, the first, the second, and the third
ports 1130, 1140, and 1150, and the fourth, the fifth and the sixth lines 113,
114
and 115.
After turning off the switch 13, the air bladder 10 can maintain its inflated
state for a predetermined period of time duo to the provision of the check
valve
1160. The air bladder 10 can be deflated by disconnecting the female
connector 116 from the male connector 117 and expelling air in the air bladder
.. 10 to the atmosphere via the fourth, the fifth and the sixth lines 113, 114
and
115, and the first, the second, and the third ports 1130, 1140, and 1150.
As shown in FIG. 4, the air bladder 10 is disposed under a lumbar zone 31
of the air mattress 3 when a user 4 lies on the air mattress 3. This
accommodates a user 4 having such preferred position.
As shown in FIG. 5, the air bladder 10 is disposed under a head zone 32 of
the air mattress 3 when a user 4 lies on the air mattress 3. This accommodates
a user 4 having such preferred position.
As shown in FIG. 6, the air bladder 10 is disposed under a leg zone 33 of
the air mattress 3 when a user 4 lies on the air mattress 3. This accommodates
a user 4 having such preferred position.

Referring to FIG. 7 in conjunction with FIGS. 1 to 5, there are three air
bladders 10 provided. The air bladders 10 are disposed under the head zone
32, the lumbar zone 31, and the leg zone 33 of the air mattress 3
respectively.
This accommodates a user 4 having such preferred position.
Referring to FIG. 8, an air supply apparatus 1 for an air mattress in
accordance with a second preferred embodiment of the invention is shown.
The characteristics of the second preferred embodiment are substantially the
same as that of the first preferred embodiment except the following: The air
bladder 10 is divided into two independent first and second air bladder
.. members 100 and 101. The first air bladder member 100 communicates with
the fourth line 113 and the second air bladder member 101 communicates with
the sixth line 115 respectively. In use, the first air bladder member 100 can
be
inflated by opening the first port 1130 and connecting the female connector
116
and the male connector 117 together. Similarly, the second air bladder member
101 can be inflated by opening the third port 1150 and connecting the female
connector 116 and the male connector 117 together. This accommodates two
users lying on a mattress having different preferred positions.
The scope of the claims should not be limited by the preferred
embodiments set forth in the examples, but should be given the broadest
interpretation consistent with the description as a whole.
