DETAILED DESCRIPTION OF THE INVENTION
[0024] Referring to FIGS. 1, 2 and 3, FIG. 1 is a perspective view
of an air mattress in accordance with a first embodiment of the
invention, FIG. 2 is a local view of the air mattress of FIG. 1
with a part thereof removed, and FIG. 3 is a sectional view of the
air mattress of FIG. 1. In the first embodiment, the air mattress 2
includes an inflatable chamber 21. The inflatable chamber 21
includes a top wall 211, a bottom wall 212 and a side wall 213. The
top wall 211, the bottom wall 212 and the side wall 213 are
connected to each other by fusion to form the inflatable chamber
21. In FIG. 3, dots 219 indicate where the fusion is.
[0025] The edges of the top wall 211 and the bottom wall 212 are
covered by trim sheets 218 so that the air mattress of this
embodiment can have an improved aesthetic appearance. Further, the
trim sheets 218 and the edges of the top wall 211 and the side wall
213 are fixed together by sewing (reference numeral 220 indicates
the sewing threads). The material of the top wall 211, the side
wall 213 and the bottom wall 212 may be plastic (for example
Polyvinyl Chloride, PVC). The material of the trim sheets 218 may
be fabric. Alternatively, the material of the trim sheets 218 may
be plastic, so that the trim sheets 218, the top wall 211, the side
wall 213 and the bottom wall 212 have the same material.
[0026] A plurality of pulling elements (e.g. sleeves, straps and
others) 214 are provided in the inflatable chamber 21 and are
connected to the top wall 211 and the bottom wall 212 by fusion.
When the inflatable chamber 21 is inflated to expand, the stretch
of the top wall 211 and the bottom wall 212 is limited by the
pulling elements 214 (under the pulling forces of the pulling
elements 214), thereby controlling expansion of the inflatable
chamber 21 to a desired shape.
[0027] It is noted that the inflatable chamber 21 has a
circumferential groove 215 for fixing a fitted bed sheet (not
shown). Specifically, a user can stretching the fitted bed sheet
(not shown) over the air mattress 2 and wrap the elastic edge (not
shown) of the fitted bed sheet (not shown) around the air mattress
2 with the elastic edge engaging the circumferential groove 215 to
keep the fitted bed sheet in place. As shown in FIGS. 2 and 3, the
side wall 213 has an upper portion 2131 next to the top wall 211
and a lower portion 2133 next to the bottom wall 212. In the first
embodiment, the circumferential groove 215 is formed by connecting
a first supplemental sheet 216 to the bottom wall 212 and the upper
portion 2131 of the side wall 213, and connecting a second
supplemental sheet 217 to the first supplemental sheet 216 and the
lower portion 2133 of the side wall 213, wherein the first
supplemental sheet 216 is angled with respect to the bottom wall
212, and the second supplemental sheet 217 is substantially
parallel to the bottom wall 212. When the inflatable chamber 21 is
inflated, the first supplemental sheet 216 and the second
supplemental sheet 217 sustain pulling forces for controlling
stretch of the side wall 213.
[0028] FIG. 4 is a sectional view of an air mattress in accordance
with a second embodiment, wherein the air mattress 2 further
includes an air permeable layer 28. Under the action of the pulling
elements 214, the top wall 211 has a plurality of depressions 2111
formed thereon. In the second embodiment, the air permeable layer
28 is additionally provided on the top wall 211 to cover the
depressions 2111 thereby improving the flatness of the air mattress
2 and user's comfort.
[0029] Under the consideration of air permeability, support ability
and manufacturing cost, the air permeable layer 28 may be (for
example) netting.
[0030] FIG. 5 is a sectional view of an air mattress in accordance
with a third embodiment, wherein the circumferential groove 215' is
formed by connecting a first supplemental sheet 216' to the top
wall 211' and the lower portion 2133' of the side wall 213', and
connecting a second supplemental sheet 217' to the first
supplemental sheet 216' and the top portion 2131' of the side wall
213', wherein the first supplemental sheet 216' is angled with
respect to the top wall 211', and the second supplemental sheet
217' is substantially parallel to the top wall 211'. When the air
mattress 2' is inflated, the first supplemental sheet 216' and the
second supplemental sheet 217' sustain pulling forces for
controlling stretch of the side wall 213'.
[0031] FIG. 6 is a sectional view of an air mattress in accordance
with a fourth embodiment, wherein the air mattress 2' further
includes an air permeable layer 28'. Under the action of the
pulling elements 214', the top wall 211' has a plurality of
depressions 2111' formed thereon. In the fourth embodiment, the air
permeable layer 28' is additionally provided on the top wall 211'
to cover the depressions 2111' thereby improving the flatness of
the air mattress 2 and user's comfort.
[0032] While the invention has been described by way of example and
in terms of preferred embodiment, it is to be understood that the
invention is not limited thereto. To the contrary, it is intended
to cover various modifications and similar arrangements (as would
be apparent to those skilled in the art). Therefore, the scope of
the appended claims should be accorded the broadest interpretation
so as to encompass all such modifications and similar
arrangements.
