Description
BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] The present invention is related to an improved structure of
an inflatable mattress, in particular, to an improved structure of
an inflatable mattress comprising a plurality of connection pieces
made of a composite material to attach an upper leather article
with a lower leather article of the inflatable mattress in order to
significantly increase a structural strength of the inflatable
mattress and to lower an overall weight thereof such that a useful
lifetime of the inflatable mattress is increased, which is a
technical field related to a new type of improved inflatable
mattress.
[0003] 2. Description of Related Art
[0004] Most of the inflatable mattresses currently known adapt the
design of an inflatable air bag with the utilization of an air
valve provided at the side of the mattress for pumping air into the
mattress for inflation thereof or to release the air by opening the
air valve in order to reduce the size of the mattress for storage
and package purposes.
[0005] Based on such fundamental structure, since most of the
traditional inflatable mattresses are of the design of the
aforementioned hollow air bag, the hollow portion between the
mattress surface and the bottom needs to be provided with a
plurality of connection pieces. Some of such connection pieces are
of a belt structure, some are of a slat structure and some are of a
column structure, which are provided to connect between the
mattress surface and the bottom thereof for the purpose of forming
the desired shape of the mattress after the inflation while, at the
same time, increasing the structural strength of the mattress.
[0006] However, the aforementioned inflatable mattresses require
the use belt shaped connection pieces, slat shaped connection
pieces or column shaped connection pieces such that all of the two
ends of the connection pieces are connected together with the
mattress (such as using the high frequency welding manufacturing
process for connection altogether). If the connection piece is
broken or the connecting portion is loose, then such one connection
piece loses its effect such that the mattress is deformed and the
useful lifetime is shortened.
[0007] Nevertheless, if a greater number of connection pieces is
used to improve the aforementioned situation, then there would be
greater uses of materials with an excess of connection pieces,
causing the manufacturing costs to be higher and the overall weight
of the inflatable mattress to increase and also making it
inconvenient to the operation as well. All of such shortcomings are
common to traditional inflatable mattresses.
BRIEF SUMMARY OF THE INVENTION
[0008] In view of the above, the present invention provides an
improved structure of an inflatable mattress capable of overcoming
the aforementioned defects and shortcomings of the traditional
inflatable mattresses effectively.
[0009] Accordingly, a primary objective of the present invention is
to provide a design using a plurality of connection pieces made of
a composite material to connect with each other between an upper
leather article and an lower leather article of the inflatable
mattress such that the structural strength of the inflatable
mattress can be significantly increased, the overall weight thereof
can be reduced and the useful lifetime of the improved structure of
the inflatable mattress can be increased.
[0010] A further objective of the present invention is to provide
an improved inflatable mattress in which the aforementioned design
for each one of the connection is of an increased structural
strength for the connection pieces themselves and an increased
number of the connecting portions with the mattress as well as a
lowered weight of the connection pieces themselves in order to
lower the overall weight of the mattress such that it is of
improvement and advantages.
[0011] To achieve the aforementioned objectives, the present
invention utilizes the following technical solutions.
[0012] An improved structure of an inflatable mattress of the
present invention comprises an upper leather article, a lower
leather article, a circumferential member and a plurality of
connection pieces to form an assembly construction thereof.
[0013] The aforementioned upper leather article, the lower leather
article and the circumferential member are identical to the ones of
the traditional mattress to form a sealed hollow mattress body.
[0014] The circumferential member comprises an air valve on the
circumferential member in order to pump air into and release air
from the hollow inner portion of the mattress.
[0015] Each one of the connection pieces comprises an upper slat
and a lower slat with a symmetrical structure; a mesh fabric is
provided between the upper slats and the lower slats to connect
therebetween.
[0016] Each one of the upper slats is connected to the upper
leather article of the mattress; each one of the lower slats is
connected to the lower leather article of the mattress; the upper
leather article and the lower leather article of the mattress are
attached to each other with the plurality of the connection
pieces.
[0017] In terms of the design, the upper slat and the lower slat of
each one of the aforementioned connection pieces are of a cross
section of a symmetrical Y shape. Such design allows the connecting
portions between each one of the connection pieces and the
inflatable mattress to be increased in order to strength the
connecting structure between each one of the connection pieces and
the inflatable mattress.
[0018] The design of the mesh fabric connected between the upper
slats and the lower slats allow a greater structural strength for
each one of the connection pieces itself and, at the same time,
reduce the leather usage of the connection slats in order to allow
the overall weight of the inflatable mattress to be light and to
achieve the predetermined objectives of the present invention.
[0019] The following provides a detailed description of the
