Abstract
A 3-layer venting mattress structure comprised of a steel fiber layer sandwiched by net layers sewn on its periphery. Both upper and lower net layers are made of fiber or non-woven with interlaced mesh for venting purposes. The steel layer between the fiber layers is made of high-strength steel yarn lop-sided woven in a spiral and continuous fashion to provide a mattress that allows excellent air permeability and tensile strength with sufficient capability to withstand local area loads. Therefore, the present invention solves the poor ventilation problem of the prior art, achieves the evenly distributed load susceptibility of the mattress, and provides an innovative type of space arrangement.
Description
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The present invention relates to a structure of a 3-layer venting mattress, and more particularly to a structure of a mattress that allows excellent air permeability and evenly distributed load susceptibility.
(2) Description of the Prior Art
The prior art generally relates to a seat cushion or bed mattress which is stuffed with sponge or other similar material to improve its comfort and is popularly available in the market; however, it gives poor air permeability and the heat cannot be easily dissipated; the user either sitting or lying on the mattress for a while feels uncomfortable about the accumulated heat inside the mattress and may get sweating on the part of the body contacting the mattress. Furthermore, the residual sweat in the mattress is vulnerable to cause sediments, mold, and odor to the affected part, resulting in hygienic problem and shorter service life of the mattress. For a chronic patient, such hygienic problem could even get more direct and serious since the attached sweat and sediment due to the poor air permeability of the mattress can easily attract the growth of bacteria and cause hazard to the patient, and in case of a patient with injury, the contact of the sweat by the wound may well cause infection. It becomes obvious that the air permeability of a mattress significantly affects the user in both comfort and health concerns.
To solve the problem of heat dissipation, a bamboo mat or a mattress woven with granules is used, but at the cost of comfort in the absence of proper softness. Either the prior art mattress, a mat or a mattress woven with granules is found defective for lacking in comfort or venting function.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a structure of a 3-layer venting mattress which is comprised of a steel fiber layer sewn in its periphery and sandwiched by upper and lower net layers to give improved comfort and excellent air permeability.
Another objective of the present invention is to provide a structure of a 3-layer venting mattress comprised of a steel fiber layer sandwiched by upper and lower net layers, that is capable of withstanding the load under the local area where the mattress contacts the body of the user to insure that the structure of the mattress will not be easily damaged under pressure while offering proper softness for practical purpose.
Another purpose yet of the present invention is to provide a structure of a 3-layer venting mattress comprised of a steel fiber layer sandwiched by upper and lower net layers with excellent air permeability that allows a direct solution to the hygienic problem of the user and a longer service life of the mattress which is less vulnerable to the contamination by the sweats of the user due to good venting.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG.
1
and
FIG. 2
, the present invention is a structure of a 3-layer venting mattress comprised of an upper net layer
10
, a steel fiber layer
20
and a lower net layer
30
sewn together with thread
40
in periphery of the mattress; said upper layer
10
and lower layer
30
are made of fiber or non-woven, the surface of each of said upper layer
10
and lower layer
30
is interlaced mesh to allow air permeation; the steel fiber layer
20
, woven in spiral, continuous and lop-sided pattern using high-strength steel yarn
25
is sandwiched between said upper layer
10
and lower layer
30
for the mattress to offer excellent air permeability.
Said steel fiber layer
20
is made of high-strength steel fiber
25
to give the mattress a firm and solid structure with sufficient capability to withstand the load on local areas, so that the structure of the mattress will not be damaged due to the pressure caused by the user sitting or lying down on it while the heat generated from the long-term contact between the mattress and the user can be well dissipated; furthermore, the softness of the mattress can be adjusted depending on the amount of said high-strength steel yarn
25
to meet the needs of each individual application.
The areas to apply the present invention is highly comprehensive. Referring to FIG.
3
and
FIG. 4
, two preferred embodiments of the present invention are illustrated.
FIG. 3
shows a mattress of the first preferred embodiment, wherein the main portion of a mattress
50
for the bed utilizes the structure of a 3-layer venting mattress. When lying on the mattress
50
, the user will not sweat from long-term contact with the mattress
50
due to its excellent air permeability; consequently the user feels very comfortable and enjoys a better quality of sleeping.
FIG. 4
shows a cushion
60
of the second embodiment of the present invention placed on a chair in an office or at home, or on a seat in a car; and the continuous use of the cushion
60
allows comfort while improving the personal hygiene and helping maintain the cushion
60
in clean condition due to the outstanding capabilities of air venting and heat dissipation.
Now referring to
FIGS. 5A and 5B
showing the present invention put under pressure; the steel fiber layer
20
made of high-strength steel yarn
25
intensively woven in the spiral, continuous and lop-sided pattern improves the structure of the mattress
50
to yield sufficient loading ability of local area when the mattress
50
is under pressure without damaging its structure while preserving the venting and heat dissipation features to be expected from the mattress.
In addition, depending on the purpose of the application, more than one 3-layer venting mattress
50
can be overlapped to allow more flexible applicability of the present invention.
When compared to the prior art of the mattress, the present invention provides the following advantages:
1. The application of the present invention achieves better air permeability and comfort;
2. The application of the present invention offers a sufficient loading capability of local area under pressure caused by the contact with the user without damaging the structure of the present invention;
3. The application of the present invention helps reduce the sweat from the user to offer a direct solution of personal hygienic problem while improving the service life of the present invention;
4. The structure of the present invention can be used for the production of cushion for chair, mattress for bed and other similar mattresses.
Claims
- 1. A multi-layer, ventilating cushion material comprising:a) a first layer of steel fiber formed in a continuous spiral, the first layer having upper and lower portions; b) an upper layer of mesh fiber material having pores to facilitate air circulation therethrough, the upper layer being interlaced with the upper portion of the first layer; and, c) a lower layer of mesh fiber material having pores to facilitate air circulation therethrough, the lower layer being interlaced with the lower portion of the first layer.
- 2. The multi-layer, ventilating cushion material as in claim 1, wherein the steel fiber comprises a high strength steel yarn.
