  First, the air circulation type mat will be described. FIG. 1 is a schematic perspective view of an air circulation mat for car seats mounted on a car seat, and FIG. 2 is a schematic cross-sectional view for explaining the principle of the air circulation mat for car seats. The air circulation mat 1 for a car seat is used by being attached to a car seat, and the outside air taken in by the air circulation mat fan 5 (hereinafter also simply referred to as a mat fan) is secured by the spacer 6. By circulating it in the space, sweat from the body is quickly evaporated to eliminate the stuffiness of the buttocks and back. For details of the principle and structure, refer to the literature, International Publication No. WO 2004/012564 (International Application No. PCT / JP03 / 09937).

  Note that a DC propeller fan using a brushless motor having a low blowing pressure can be used by using a spacer having a very low air resistance as in Japanese Patent No. 4067034 as the spacer. A DC propeller fan (hereinafter also simply referred to as a fan) is a mass production of a long-life and square product as a cooling fan for various electric devices. However, both are made to be screwed to a panel of an electric device and cannot be used as a mat fan as it is.

(First embodiment)
FIG. 3 is a schematic perspective view of a fan holder, which is a main component of the air circulation mat fan according to the first embodiment of the present invention, and FIG. 4A is an air circulation mat according to the first embodiment of the present invention. FIG. 5 is a schematic front view of a fan holder which is a main component of the fan for use in the present invention, FIG. 5B is a schematic side view thereof, and FIG. 5 is a schematic perspective view of a DC propeller fan which is a main component of the fan for an air circulation type mat of the present invention FIG. 6 is a schematic back view of the air circulating mat fan according to the first embodiment of the present invention. The mat fan 5 of this embodiment includes a fan 11 and a fan holder 10 integrated with the fan 11. The fan holder 10 accommodates the fan 11 and is securely attached to the air circulation mat so that there is little air leakage from the attachment portion of the air circulation mat and does not come off the main body of the air circulation mat. is there.

  As shown in FIGS. 3 to 6, the fan holder 10 of the present embodiment includes a rectangular tube-shaped leg portion 12 for housing the fan and an upper end portion of the leg portion for connecting the upper end portions of the leg portions. A connecting portion 13 formed on the outer surface of the leg portion so as to surround the leg portion, a surface fastener A17 attached to the surface of the attaching plate on the connecting portion side, A cord clamp (fastener) 16 provided on the surface opposite to the surface on the connecting portion side of the plate, and a plurality of fan spacer portions 18 provided so as to extend the leg portions are provided. In the present embodiment, a finger guard 15 and an air circulation part 19 are formed in the connecting part 13.

  In the fan holder 10 of the present embodiment, the portion excluding the surface fastener A can be integrally formed by plastic injection molding. That is, the fan holder of the present embodiment can be easily manufactured by attaching the planar fastener A to an integrally molded plastic molded product. In this embodiment, the fan holder and the fan are integrated with an adhesive. Due to such a structure, in this embodiment, the rotating surface of the propeller and the mounting plate are parallel.

  FIG. 7A is a schematic partial front view of the vicinity of the mat fan of the air circulation mat, and FIG. 7B is a schematic partial cross-sectional view taken along the line A-A ′. A mounting hole 30 having a size corresponding to the leg portion of the mat fan is opened in the front sheet 2 of the air circulation mat 1, and a sheet fastener B3 is sewn on the back surface around the mounting hole 30. . Further, the sheet 2 on the back side of the air circulation type mat is provided with a fastener 20 for performing an attaching / detaching operation of the mat fan at a position corresponding to the mat fan.

  When attaching the mat fan 5 of the present embodiment to the air circulation mat 1, the fastener 20 is opened, the mat fan 5 is placed in the air circulation mat 1, and the mating fan 5 is connected to the attachment hole 30. By inserting the 13th side, the sheet fastener B3 attached around the attachment hole 30 and the sheet fastener A17 of the mat fan 5 are bonded. In this way, the mat fan 5 can be easily attached to the air circulation mat. In this case, when the mat fan is attached, it is desirable to set the distance between the attachment plate 14 and the upper end (connecting portion) of the leg portion 12 so that the leg portion 12 protrudes to the outside through the attachment hole 30. This is because the larger the protruding amount of the upper end of the leg, the easier it is for the leg to serve as a guide when attaching.

  In addition, four fan spacer portions 18 are formed on the leg portion 12 of the fan holder 10, and the fan spacer portion 18 ensures a sufficient space between the fan propeller and the back sheet of the air circulation mat. Therefore, the air resistance in the vicinity of the fan 11 is reduced, and sufficient outside air can be efficiently taken into the air circulation mat.

  According to this embodiment, even if the adhesion between the surface fasteners is removed due to impact or the like, the mat fan is larger than the attachment hole 30, so the mat fan stays inside the air circulation mat and is outside. It will not fall. This is particularly important for air-flowing mats for car seats. In the case of the conventional system, the fan and related parts may fall, and if it enters between the floor and the accelerator or brake pedal, it may cause a serious accident.

  Further, according to the present embodiment, since the mat spacer is detachably attached to the air circulation type mat using the planar fastener, the surface resistance is higher than the air resistance of the air flow passage formed by the spacer 6. Since the air resistance of the bonding surface between the sheet-like fasteners is sufficiently large, the amount of air leaking from the gap between the sheet-like fasteners is small, and the cooling performance is not impaired.

  Furthermore, according to the present embodiment, a mat fan can be manufactured simply by adhering a commercially available DC propeller fan to a fan holder formed using a resin with an adhesive. Since the fastener is attached to the air circulation type mat, the mat fan of the present embodiment has a simple structure, and the user can easily attach to and detach from the air circulation type mat.
