In the peripheral portion of the cover main body, a rubber string-containing gather portion for fixing the cover main body to the helmet is provided at a peripheral inner portion of the helmet, and the plurality of flaps are respectively provided from the gather portion to the helmet. The flaps extend inward, and the ends of the respective flaps are connected to each other by connecting means such as a string at the top of the inner circle of the helmet.

In the present invention, as a cover for covering the inside of the helmet, four flaps, which are divided into a front surface, a rear surface, and both right and left sides, from the peripheral portion of the cover body covering the outside of the helmet, are respectively directed inward of the helmet. Let it extend,
A loop cord is provided at the tip of three flaps of these flaps, and a hook-through string provided at the tip of one flap is passed through each of the loop cords. It is preferable to adopt a configuration in which the helmet inner circle is integrally connected at the top.

[0008]

In the dust-free helmet cover according to the present invention, the outer surface of the helmet is covered by the main body cover, and the means for covering the inner surface of the helmet is as follows.
By projecting flaps divided into a plurality of front, rear, left and right from the gather part at the lower end of the main body cover, the flaps on both left and right sides of each of these flaps pass through the inside of the helmet's chin strap, respectively. The flaps of the helmet overlap each other in the direction of the helmet. Can be accurately prevented.

Each of the flaps bent toward the inside of the helmet guides the tip end having a loop string and a pass-through string from between the cushion belts in the helmet to the inside of the cushion plate at the top of the inner helmet circle. The entire cover can be firmly fixed to the inner and outer surfaces of the helmet by inserting the straps of the flaps into the loops of the other flaps and finally tangling the ends of the flaps together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a dust-free cover for a helmet according to the present invention will be described with reference to one embodiment shown in the drawings. As shown in FIGS. A cover body 2 formed of a fabric subjected to an antistatic treatment to be coated, and a plurality of flaps for covering the inside of the helmet extending inward of the helmet 1 from the peripheral edge 3 of the cover body 2 It consists of four.

As shown in FIG. 2, a rubber string-containing gather portion 5 for fixing the cover body 2 to the helmet 1 is provided on the inner peripheral portion of the helmet 1 at the peripheral portion 3 of the cover body 2. The plurality of flaps 4 for covering the inside of the helmet 1 are provided below the elastic string gathers 5.

Each of the plurality of flaps 4 covering the inside of the helmet 1 includes a front flap 4a having a tapered tip, a rear flap 4b, and left and right side flaps 4c and 4d. The front flap 4a and the rear flap 4b are wide and the left and right side flaps 4c and 4d are slightly narrower. The three flaps of the rear flap 4b and the left and right side flaps 4c and 4d are provided. Is provided with a loop string 6 at the tip of the female hook 8b at the tip of the remaining one front flap 4a.
, A through string 7 having a male hook 8a at the end is protruded.

When the dust-free cover is mounted on the helmet 1, the cover main body 2 is put on the outside of the helmet 1 and the gathering portion 5 with the rubber string of the peripheral portion 3 is positioned inside the peripheral portion of the helmet 1. The cover body 2 is firmly fixed to the outside of the helmet 1. Next, as shown in FIG. 3, the left and right side flaps 4c and 4d are folded back inward of the helmet so as to pass through the inside of the chin strap 9 of the helmet 1, and the front flap 4a and the rear flap 4b are also directed inward of the helmet. Wrap back to
