Description

Folding mat {FOLDING MAT}

The present invention relates to a foldable mat, and more particularly, to a foldable mat on which a mat is foldably connected, a conductive line can be arranged without a separate connection portion, and a length can be adjusted by a lead- To a folding mat capable of preventing damage to conductive lines, improving durability and productivity, and reducing manufacturing costs.

In general, a mat used as a bedding or the like is manufactured in a folding type in consideration of convenience of use, storage and handling.

For example, a foldable mat is proposed as a foamed material folding mattress as disclosed in Korean Utility Model Laid-Open Publication No. 20-2017-0000971.

The foamed material folding mattress includes a plurality of unit shells 150 having a receiving space 170 formed therein and a plurality of unit shells 150- 1, a central mattress portion 300 is inserted, and an outer mattress portion 400 is inserted into unit sheaths 150-2 located on both sides.

However, the foamed material folding mattress is not equipped with its own heating device, and thus, there is a disadvantage that a separate heating device such as an electric laminate or the like must be installed when it is used in the home or outdoor in winter.

To solve these drawbacks, Korean Utility Model Laid-Open No. 20-2013-0004950 proposes an electric panel mat for folding heating, which is provided with a heating device by itself.

As shown in Figs. 1A and 1B, the conventional electric folding panel mattress for heating is provided with an iron plate 10; A heat line (20); A jack (21); An aluminum plate (40); A ceramic (S); An electric panel (A) formed by foaming a hard urethane (30) in the steel plate (10); An iron plate 10 '; A heat line (20); A bimetal 23; An aluminum plate (40); A ceramic (S); An electric panel (B) made by foaming a hard urethane by making a hole in the side of the steel plate; A wiring connecting line 22 for connecting one side of the hot wire 20 of the electric panel A and one side of the hot wire 20 of the electric panel B and wiring in parallel to allow electricity to pass therethrough; A rectangular cover 50 for accommodating the electric panel A and the electric panel B connected to the wiring connecting line 22; A handle 55 attached to the cover 50, a fixing band 53 for fixing the electric panels A and B when the electric panel A and the electric panel B are folded, And a controller accommodating portion 56 capable of accommodating the regulator 60 and the power cord 70. [

The conventional foldable heating electric panel mats are capable of performing a heating operation with a built-in heating wire, but they involve various problems as follows.

1, a foldable heating electric panel mat is formed by arranging heat wires 20 on one electric panel A and the other electric panel B, and then connecting wiring lines 22 ) Must be separately connected to each other, which complicates and complicates the operation.

Particularly, in the case where the electric panels A and B are composed of a plurality of three or more, or when two or more heat wires are arranged in different paths, the number of connection lines 22 is excessively large, It takes a long time, resulting in an increase in manufacturing cost and a decrease in productivity.

Since the portion of the wiring connecting line 22 is repeatedly folded together with the folding operation of the electric panels A and B, the rigidity of the connecting portion formed by soldering or the like is weakened to cause damage or breakage. There is a drawback that it occurs.

The electric folding heating electric panel mat may be used for binding the heating wire 20 to the electric panel A and the jack 21 for coupling with the regulator 60 when assembling the heating wire 20 to the electric panels A and B, However, if it is difficult to adjust the margin, it is difficult to adjust the margin. If the margin is shortened, the assembling failure is caused. If the margin is too long, repeatedly folding due to sagging causes damage to the heat wire 20 and durability There is a drawback that it causes deterioration.

In addition, the foldable heating electric panel mat is provided with a cover 50 which covers the outside of the electric panels A and B, and the electric panels A and B are divided by the seam 51 of the cover 50 And is folded on the basis of the seam, but there is a disadvantage that the sewing needle damages the heat ray 20 at the time of sewing the seam.
