Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a queen size air bed, and
more particularly to a queen size air bed with a baffle securely
received in the air bed to separate the air bed into two portions
so that influence caused by vibration in one portion and
transmitting to the other portion is minimized.
[0003] 2. Description of Related Art
[0004] With reference to FIG. 1, a conventional air bed (9) is
shown. The air bed (9) is made of plastic or the like. When the air
bed (9) is in use, air is pumped into the air bed (9). When the air
bed (9) is not in use, the operator is able to discharge the air
inside the air bed (9) to deflate the air bed (9) so that the air
bed (9) is able to be stored in a compact space.
[0005] The air bed (9), no matter the size, is easily influenced by
any kind of vibration in any portion of the air bed (9). That is,
if one person sleeping on one side of the air bed (9) turns or gets
up in the middle of the night, no matter how carefully the person
moves, the slightest vibration transmits easily to every portion of
the air bed (9), such that if there is another person sleeping on
the air bed (9), the vibration becomes disturbing.
[0006] To overcome the shortcomings, the present invention tends to
provide an improved air bed to mitigate and obviate the
aforementioned problems.
SUMMARY OF THE INVENTION
[0007] The primary objective of the present invention is to provide
an improved air bed with a baffle in the air bed so that influence
caused by vibration on one side of the air bed to the other side of
the air bed is minimized.
[0008] Other objects, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] With reference to FIG. 2, the air bed (1) in accordance with
the present invention includes a baffle (2) inside a hollow body
(10) of the air bed (1) to separate the body (10) into a first
chamber (11) and a second chamber (12). The baffle (2) engages with
inner surfaces of two opposite sides of the air bed (1).
[0016] With reference to FIG. 3, an electrical motor (3) is mounted
on a side-surface of the first chamber (11) for charging and
discharging air of the first chamber (11) of the air bed (1). A
switch (4) mounted on an outer surface of the second chamber (12)
is able to control a control valve (5) which is mounted on the
baffle (2) to control communication between the first chamber (11)
and the second chamber (12). Thus, when the switch (4) operates the
control valve (5) to communicate the first chamber (11) with the
second chamber (12), air pumped by the electrical pump (3) is able
to flow into the second chamber (12). However, if the switch (4)
operates the control valve (5) to close communication between the
first chamber (11) and the second chamber (12), the air from the
electrical pump (3) will not flow into the second chamber (12). A
unidirectional air discharging valve (6) is mounted on the outer
surface of each of the first chamber (11) and the second chamber
(12) so that either one or both of the first chamber (11) and the
second chamber (12) is/are able to discharge air separately or
simultaneously.
[0017] A foot pump (7) is provided in both the first chamber (11)
and the second chamber (12). The foot pump (7) has a hollow
cylindrical bellow, an air hole (71) defined to communicate with
air outside the air bed (1), a unidirectional membrane (72) mounted
on top of the air hole (71) to regulate air inflow from outside the
air bed (1) and an outlet (73). Therefore, when the operator
repeatedly steps on the bellow, air outside the air bed (1) is
sucked in the bellow through the unidirectional membrane (72) and
out of the foot pump (7) from the outlet (73) to charge the first
chamber (11) and/or the second chamber (12).
[0018] With reference to FIGS. 4, 5, 6A and 6B, it is noted that
only the baffle (2) engages with opposite inner sides of the air
bed (1) to separate the first chamber (11) and the second chamber
(12) in an air-tight manner. The other portions inside the air bed
(1) are away from engagement with the opposite inner side faces of
the air bed (1). Thereafter, when either the electrical pump (3) or
the foot pump (7) is activated, the first chamber (11) and/or the
second chamber (12) can be charged.
[0019] Furthermore, the air bed (1) of the present invention has
fixing straps (8) each formed inside the air bed (1) and securely
connected to opposite inner side faces of the air bed (1) to
maintain the shape of the air bed (1) when the air bed (1) is
charged so that deformation of the air bed (1) is prevented.
[0020] It is to be understood, however, that even though numerous
characteristics and advantages of the present invention have been
set forth in the foregoing description, together with details of
the structure and function of the invention, the disclosure is
illustrative only, and changes may be made in detail, especially in
matters of shape, size, and arrangement of parts within the
principles of the invention to the full extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
