INFLATABLE MAT HAVING BLOCKING STRUCTURE

Description

FIELD OF THE INVENTION

The present invention relates to an inflatable mat, and more particularly to an inflatable mat having a blocking structure. The inflatable mat is light in weight and capable of blocking air convection and temperature radiation.

BACKGROUND OF THE INVENTION

Despite the busy and stressful lives, people pay more attention to outdoor recreational activities to regulate their physical and mental stress. Especially after the COVID-19 epidemic is lifted, many tourists will travel abroad to make up for the restrictions on their activities during the epidemic.

In recent years, more and more people love outdoor leisure activities, including camping and climbing. In addition to preparing enough food and drinking water, it is very important for keeping warm. If there are no enough equipages to keep out the cold, a person may suffer from hypothermia, which will cause trembling, unconsciousness, or mental disorder. However, if a person suffers from severe hypothermia, it will cause shock, cardiac arrest, and deadly danger. The so-called super marathon plays in the polar region for several days. This region is dozens of degrees below minus all year round. People may suffer from frostbite and hypothermia easily. Participating or challenging polar sports requires complete, top-level equipages to reduce risks.

For all night-time activities, people may suffer from hypothermia when sleeping at night because the temperature is lower at night. If a person lies directly on the ground, the low-temperature conduction of the ground will increase the chance of suffering from hypothermia. Thus, people often put a layer of aluminum foil pad under the sleeping mat to reduce the low-temperature conduction of the ground. However, the effect of keeping out the cold for this single-layer aluminum foil pad is not good. If it is used in polar climate, the effect of keeping out the cold is very poor. Furthermore, outdoor activities, such as camping, need a lot of equipages. It is required for all equipages to be lightweight. Equipages need to meet the requirements of being light, easy storage and the like, which indirectly affect functional improvements. As to sleeping mats on the market, the effect of keeping out the cold is not good, or the sleeping mat is heavy. If this sleeping mat is used in the polar environment, it cannot meet the requirements.

The structure and effectiveness of the existing mats are still not ideal and need to be improved. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide an inflatable mat having a blocking structure. The inflatable mat can be deflated to reduce its size when not in use. The inflatable mat is made of light and thin sheets that are connected to each other, thus meeting the basic needs of lightness and portability. The interior of the inflatable mat has a plurality of spaced spaces that are partitioned using a variety of materials. The inflatable mat is able to block air convection and reduce temperature radiation effectively.

In order to achieve the foregoing object, the inflatable mat provided by the present invention comprises a top covering layer, a bottom covering layer and a plurality of strip-shaped connecting members connected between the top covering layer and the bottom covering layer. The peripheries of the top covering layer and the bottom covering layer are joined and closed. The connecting members are thin and light. A plurality of blocking units are disposed between the top covering layer and the bottom covering layer, so that a plurality of spaced spaces are formed among the top covering layer, the blocking units and the bottom covering layer, so as to block air convection and temperature radiation.

Preferably, the blocking unit includes a first blocking unit. The first blocking unit is composed of a polyester film material (Mylar®) and a non-woven fabric that are laminated. A portion of the top of the first blocking unit is connected to the bottom of the top covering layer. The number of layers of the polyester film material (Mylar®) and the non-woven fabric may be increased or decreased as needed. Preferably, there is an appropriate distance between the polyester film material (Mylar®) and the non-woven fabric when they sag.

Preferably, the blocking unit includes a second blocking unit. The second blocking unit is made of a thermoplastic polyurethane (TPU) material. The second blocking unit is laminated below the first blocking unit. There is an appropriate distance between the second blocking unit and the first blocking unit when they sag.

Preferably, the blocking unit includes a third blocking unit. The third blocking unit is composed of a polyester film material (Mylar®) and a non-woven fabric that are laminated. A portion of the bottom of the third blocking unit is connected to the top of the bottom covering layer. The number of layers of the polyester film material (Mylar®) and the non-woven fabric may be increased or decreased as needed. There is an appropriate distance between the polyester film material (Mylar®) and the non-woven fabric when they sag.

The inflatable mat is a seat mat or a sleeping mat, and the size of the inflatable mat can be changed as required.

Preferably, the inflatable mat is equipped with a nozzle, which can be inflated or deflated as required for portability. This is a known art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

Referring to FIG. 1 and FIG. 2, the present invention discloses an inflatable mat 1, comprising a top covering layer 11, a bottom covering layer 12, and a plurality of strip-shaped connecting members 13 connected between the top covering layer 11 and the bottom covering layer 12. The peripheries of the top covering layer 11 and the bottom covering layer 12 are joined and closed. The connecting members 12 are thin and light.

A plurality of blocking units 14, 15, 16 are disposed between the top covering layer 11 and the bottom covering layer 12, so that a plurality of spaced spaces are formed among the top covering layer 11, the blocking units 14, 15, 16 and the bottom covering layer 12, so as to block air convection and temperature radiation.

The blocking unit includes a first blocking unit 14. The first blocking unit 14 is composed of a polyester film material (Mylar®) and a non-woven fabric that are laminated. A portion of the top of the first blocking unit 14 is connected to the bottom of the top covering layer 11. The number of layers of the polyester film material (Mylar®) and the non-woven fabric may be increased or decreased as needed. Preferably, there is an appropriate distance between the polyester film material (Mylar®) and the non-woven fabric when they sag.

The blocking unit includes a second blocking unit 15. The second blocking unit 15 is made of a thermoplastic polyurethane (TPU) material. The second blocking unit 15 is laminated below the first blocking unit 14. Preferably, there is an appropriate distance between the second blocking unit 15 and the first blocking unit 14 when they sag.

The blocking unit includes a third blocking unit 16. The third blocking unit 16 is composed of a polyester film material (Mylar®) and a non-woven fabric that are laminated. A portion of the bottom of the third blocking unit 16 is connected to the top of the bottom covering layer 12. The number of layers of the polyester film material (Mylar®) and the non-woven fabric may be increased or decreased as needed. Preferably, there is an appropriate distance between the polyester film material (Mylar®) and the non-woven fabric when they sag.

As shown in FIG. 1 and FIG. 2, the first blocking unit 14, the second blocking unit 15 and the third blocking unit 16 are disposed between the top covering layer 11 and the bottom covering layer 12.
