The present invention relates to a head pad device of a hard hat designed to wear more by adjusting the size of the head pad of the hard hat to fit accurately to the head and to prevent hair loss during work.

In general, the helmet has a structure in which the head pad (2) that is in contact with the head in the interior as shown in Figure 1 is installed, the head pad (2) is caught in the fall prevention band (3) (3 ') in the back of the head when leaned forward While the structure is such that it does not peel off, a plurality of headrest bands 7 which are bound to the band hanger piece 6 are alternately installed so as to be worn over the head when wearing a hard hat.

However, this simple head pad structure does not faithfully function as a safety helmet because it cannot be used to adjust exactly to everyone considering that the size and shape of the head and the size of head circumference are different for each person who wears a hard hat. Failure was caused.

That is, in the conventional head pad 2, the head restraint band 7 is simply staggered and thus only maintains a constant height (depth) at all times in the safety helmet part 1a. Therefore, when the long head is worn by the person, the visor is worn much higher up the forehead, while when the shorter head is worn, the visor gets deeper into the head hanging band (7). As it is worn down to the eye area under the forehead, it causes the problem of obstructing the front view or easily peeling off and becoming awkward.

In addition, the separation prevention band (3) (3 ') of the head pad (2) is to be tightened to be locked to the back of the head, but the binding piece (5) of the head pad (2) is coupled to the binding groove (4) of the hard hat (1) Since the front part of the head pad 2 is not tightened because the entire head pad 2 is not tightened, when a person with a large head circumference is worn, the pad circumference is small and placed on the head. In addition to being worn, in the case of a person with a small head circumference to be worn loosely, the hard hat during the operation caused hair loss or moving at will, causing work interruption and causing the wearing of a hard hat.

The present invention allows the headrest band to adjust the height of the headrest band from the safety helmet, and to adjust the pad circumference to fit the size of the head, while preventing hair loss during work. The goal is to be able to wear the helmet in the most comfortable state.

In order to achieve the above object, the present invention tightens or extends the head restraint band at the center part so that the head wearing depth can be adjusted while the tightening band is bound at both ends of the head pad to the binding hole at the rear end. By adjusting the tightening band to fit the head circumference size, as described below in more detail based on the accompanying drawings.

In FIG. 3 showing an exploded perspective view of the present invention, reference numeral 1 denotes a hard hat, 2 denotes a head pad, and the head pad 2 has a catching tooth 3a and a toothed groove 3b at its rear end. A band hanger piece 6 having a separation prevention band 3 and 3 ', each having a binding piece 5 inserted into a binding groove 4 of a hard hat 1 at equal intervals. It is known to have been installed.

Therefore, the present invention is formed so that the band hanger piece 6 is formed so that the outer end portion 70a of the head restraint band 70 is bound to each other, but has a length that reaches only the central portion. Hanging string (8) is passed through the binding hole (71) to form a circle and then to be a string bundle.

In addition, the present invention is to have a tightening band 10, the tightening band 10 is a resin band paper (10b) is attached to the inside of the fabric band paper (10a) having flexibility and the other end is attached to The binding piece 11 which connects and binds the binding band part 10c which forms an end part is connected.

The fastening band 10 is to be coupled to the clip 12 having the engaging carbon piece 12a and the binding piece 12b at equal intervals, the binding piece 12c of the clip 12 is the fabric band 10a ) Is sandwiched between the resin band paper 10b.

Therefore, the present invention inserts the head pad 2 in the clip 12 so that the tightening band 10 is located toward the inner surface of the head pad 2 in the state where the binding piece 12b of the clip 12 is opened, and then the binding piece 12b. ) To press the engaging bullet piece 12a, and to fasten the tightening band 10 to the inner surface of the head pad 2 using the respective clips 12 in the above-described manner.

As described above, the head pad 2 to which the tightening band 10 is bound is installed inside the hard hat 1 while being finally inserted so that the binding piece 5 is inserted into the binding groove 4.

In the figure, reference numeral 3c is a band guide guide, 8a is a bundle knot, h, h 'shows the wearing depth of the head.

Therefore, the present invention is to wear after adjusting the head wearing depth (h) (h ') and the circumferential size using the hook strap 8 and the tightening band 10 before wearing the safety helmet (1).

In the control of the strap 8, when the string ends 8a are pulled or loosened, the inner end 70b of the headband band 70 is drawn as shown in the solid and imaginary lines of FIG. It will either be centered or vice versa. Therefore, when the head restraint band 70 is made of a material without elasticity during such adjustment, the inner end portion 70b is adjusted to be widened (FIG. 5 solid state). As the diameter of the tube increases, the inner end portion 70b enters the inner portion of the hard hat 1 so that the inner end portion 70b can be positioned and adjusted to a deep wearing depth h, while the inner end portion 70b converges toward the center portion. If the hanger 8 is tightened (figure 5), the diameter of the hanger 8 becomes smaller as shown in FIG. 6, and the inner end 70b is lowered to lower the head. The depth h 'will be adjusted.

Therefore, the helmet wearer should adjust the head wearing depth (h) (h ') with the hanger (8) in a state suitable for the depth of his head, and then tie the hanger (8) to the tie knot (8a). (h) (h ') adjustment is completed.

Next, wearing a hard hat (1) is to adjust the circumference size at this time, the binding band (10c) of the fastening band 10 to the binding piece (11) to bind but pull the binding band (10c) to fit the wearer's head ties To make it happen. Therefore, when pulling the binding band portion 10c as described above, the tightening band 10 having flexibility is tightened. The fastening band 10 is also suspended from the head pad 2 by the clip 12, so the front part is also up. With the tightening force, the size of the circumference of the tightening band 10 is adjusted to the size of the wearer's head.

And since the tightening band 10 is located inside the hard hat 10 as shown in FIG. 7 so that the fastening band 10 is not visible from the outside, the fastening band 10 does not impair the appearance of the hard hat 1, and finally the fastening band part 10c is attached to the fastening piece 11. ) Is tied to a stagger, so once you adjust it, you don't need to adjust it as long as you keep using it.

According to the above description, the present invention can adjust the wearing depth of the helmet to suit the wearer's head size, and can be worn by adjusting the circumference size, thereby making it possible to wear a comfortable helmet while moving without losing hair during work. This will provide the effect of promoting the wearing of helmet without it will be able to further increase the reliability of the product.
