Portable mat capable of blocking air convection and temperature radiation

Abstract

A portable mat capable of blocking air convection and temperature radiation is disclosed. The portable mat is an inflatable mat, and includes a first outer covering layer and a second outer covering layer that are connected by a plurality of connecting members each in the form of a thin and light ring. Side pieces of the connecting members each have different widths according to high and low positions. A plurality of blocking layers of a blocking unit is fitted on the connecting members. The block layers have openings with different widths. The openings of the blocking layers are different in size corresponding to the different widths of the connecting member, so that the blocking layers are positioned at different heights to form a plurality of spaced space inside the mate, thereby blocking air convection and reducing temperature radiation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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

(7) Please refer to FIG. 1, FIG. 2 and FIG. 3. The present invention discloses a portable mat 1 capable of blocking air convection and temperature radiation. The mat 1 is an inflatable structure. The mat 1 comprises a first outer covering layer 11, a second outer covering layer 12, and a space 13 defined between the first outer covering layer 11 and the second outer covering layer 12. The peripheries of the first outer covering layer 11 and the second outer covering layer 12 are joined and closed.

(8) The first outer covering layer 11 and the second outer covering layer 12 are connected by a plurality of connecting members 2. The connecting member 2 is in the form of a thin and light ring. The connecting member 2 may consist of two sheets joined together, or it may be a single-sheet integrated structure. A first joining portion 21 is disposed on the top of the connecting member 2. The first joining portion 21 is joined to the inner edge of the first covering layer 11. A second joining portion 22 is disposed on the bottom of the connecting member 2. The second joining portion 22 is joined to the inner edge of the second covering layer 22. The connecting member 2 includes two corresponding side pieces 23. The side piece 23 is designed to have different widths according to height and low positions. In this embodiment, The side piece 23 has a trapezoid shape with a narrow upper portion and a wide lower portion.

(9) The present invention further comprises a blocking unit 3 fitted on the connecting member 2. The blocking unit 3 is composed of one or more than two blocking layers. In this embodiment, the blocking unit 3 has six layers (the number of layers can be increased or decreased arbitrarily), including a first blocking layer 31, a second blocking layer 32, a third blocking layer 33, a fourth blocking layer 34, a fifth blocking layer 35, and a sixth blocking layer 36. A plurality of first openings 311 is defined in the first blocking layer 31. A plurality of second openings 321 is defined in the second blocking layer 32. A plurality of third openings 331 is defined in the third blocking layer 33. A plurality of fourth openings 341 is defined in the fourth blocking layer 34. A plurality of fifth openings 351 is defined in the fifth blocking layer 35. A plurality of sixth openings 361 is defined in the sixth blocking layer 36. The openings correspond in position to the connecting members 2. Because the side piece 23 of the connecting member 2 is designed to have different widths according to height and low positions, with a narrow upper portion and a wide lower portion, the widths of the first opening 311 to the sixth opening 361 gradually increase. As shown in FIG. 3, after the blocking layers 31, 32, 33, 34, 35, 36 are fitted on the connecting member 2, they are held and positioned by the corresponding widths of the side piece 23 according to high and lower positions, so that the blocking layers 31, 32, 33, 34, 35, 36 are spaced apart from each other to form a plurality of spaced spaces. Because the spaced spaces are not in communication with each other, they can be used to block air convection and temperature radiation. Thus, when the mat 1 is used in a polar environment, it can effectively resist the low temperature on the ground and prevent the user from suffering hypothermia.

(10) FIG. 4 and FIG. 5 illustrate a second embodiment of the present invention. The side piece 23 of the connecting member 2 is changed from the trapezoid shape having a narrow upper portion and a wide lower portion to a regular hexagon shape having narrow upper and lower portions and a wide middle portion.

(11) In addition, the side piece 23 may have various modifications and enhancements. All the features of utilizing different heights of the connecting member 2 to match the openings with different widths for locking and positioning the blocking unit 3 are all within the scope of the present invention.
