Abstract

(57) [Abstract] [Purpose] The opening of the concave groove for storing the connecting cord of the heating tatami mat is removed from the corner of the tatami floor to prevent damage during transportation, and when the heating tatami mat is laid in the room, each tatami mat is covered. Obtain a heating tatami mat that is easy to connect between connecting cords. [Structure] A concave groove is provided in the central portion of the lower surface of the tatami floor in the longitudinal direction and at a position approximately one-fourth of the total length of the tatami from the end surface in the width direction. Connect the cords in sequence to supply power to each heating tatami mat.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a heating tatami having a heating element on the upper surface of a tatami floor.

[0002]

[Prior Art]

 In order to supply power to each heating tatami mat laid in a room, it has been known that a groove is provided from the central part of the lower surface of the tatami mat to two required corners and a connection line is provided in this groove. (See, for example, Japanese Utility Model Publication No. 2-7381).

[0003]

[Problems to be solved by the device]

 In the above conventional technique, since the opening of the groove is located at the corner of the heating tatami mat, the corner is easily damaged during transportation. There was a problem that it was difficult to connect the connecting wires.

The present invention solves the above problems of the prior art, and provides a heating tatami that does not have a groove opening at the corner of the heating tatami and facilitates electrical connection between heating tatami mats. The purpose.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a heating tatami mat having a heating element, in which a concave groove is provided substantially in the center in the longitudinal direction of the tatami floor, and the width of the tatami mat is about 4 minutes from the end face. A concave groove is provided at a part of the above, the connection cord electrically connected to the heating element is housed in the concave groove in the previous period, and power is supplied to each heating element by sequentially connecting the connection cord. The heating element and the connection cord are electrically connected by a detachable connector.

[0006]

[Action]

 The connection cord is mounted in a desired groove depending on the laid condition of the tatami mat, the adjacent tatami mats are electrically connected by connecting the respective connection cords, and the connection cord and the heating element are electrically connected by the connector.

[0007]

【Example】

 FIG. 1 is a rear perspective view of a heating tatami mat 1. A longitudinal groove 3 and a width groove 4 are provided in a cross shape on the lower surface of a tatami floor 2 having a heating element (not shown) on the upper surface. Has been. One of the grooves 3 is located substantially in the center, and the other groove 4 is located at about 1/4 of the total length of the tatami mat from the end face. The concave groove 4 may be provided on the other end surface.

The connection cord 6 has substantially the same length as the tatami mat, and its central portion is connected to the power supply line 5 of the heating element. This connection is removable by a male and female connector 7 in order to facilitate the electrical connection between the tatami floor 2 and the connection cord 6.

The power supply line 5 and the connection cord 6 may have a spiral shape (not shown) whose ends are expandable and contractable. In this case, the concave groove of the corresponding portion for accommodating the spiral shape is enlarged. I'll do it. Further, both ends of the connection cord 6 are a male connector 8 and a female connector 9 which are fitted to each other and electrically connected to each other, and the entire length thereof is housed in the concave grooves 3 and 4 as shown in FIG.

FIG. 3 shows a power supply path to each heating tatami mat 1 laid in the room, and in order to electrically connect the connecting cords 6 sequentially from the outer tatami mat to the inner tatami mat, the groove of the adjacent tatami mat is used. The connection cord 6 is remounted in the optional groove 3 or 4 in accordance with the position where the groove 3 or the groove 4 coincides with each other (for example, the position indicated by the chain line in FIG. 2).

[0011]

[Effect of the device]

 According to the present invention, since the opening of the groove is on the side surface of the tatami floor as described above, damage to the tatami floor can be prevented without paying special attention to the corner of the tatami floor during transportation.

Further, since the concave groove is provided in the central portion in the longitudinal direction and in the width direction of a quarter portion from the end surface, when the heating tatami mat is laid in the room, the connecting part of the connecting cord between the adjacent tatami mats is formed. Does not come to the wall surface of the building, and the connecting cord on the upper connecting part is always straight, so that the laying work can be done easily and quickly.

Further, since the connection cord is detachably attached to the power source line of the heating element, it is easy to attach the connection cord to the tatami floor, and the work such as repair and replacement after laying becomes easy.
