In describing the present embodiment, the same names and the same reference numerals will be used for the same elements, and additional description according thereto will be omitted.

(10) FIGS. 1 and 2 are views illustrating a state of a helmet main body 12 to which a detachable pad fastening structure of a helmet according to a first embodiment of the present disclosure is applied, and FIG. 3 is a view illustrating a state of a detachable pad 100 to which the detachable pad fastening structure of the helmet according to the first embodiment of the present disclosure is applied.

(11) FIG. 4 is a view illustrating a state in which the helmet main body 12 and the detachable pad 100 are coupled by the detachable pad fastening structure of the helmet according to the first embodiment of the present disclosure.

(12) As illustrated in FIGS. 1 to 4, a helmet 10 according to the present disclosure includes the helmet main body 12 and the detachable pad 100.

(13) In the present embodiment, a transparent part 14 for securing visibility of a wearer is disposed at a front surface of the helmet main body 12, and the detachable pad 100 has a fitting part 120 coming into contact with chin and neck portions of the wearer to fit the size, and a second coupling part 110 corresponding to a first coupling part 20 of the helmet main body 12.

(14) In this case, a first fastening unit and a second fastening unit for coupling between the helmet main body 12 and the detachable pad 100 are formed at the first coupling part 20 and the second coupling part 110. Hereinafter, the first fastening unit and the second fastening unit will be described in detail.

(15) The first fastening unit is formed at the first coupling part 20 formed at both sides of an inner surface of the helmet main body 12, and includes a first fastening member 22 having a fastening hole 23 formed therein. In the case of the present embodiment, a plurality of first fastening members 22 are disposed to be spaced apart from each other in the first coupling part 20.

(16) The second fastening unit includes a through-hole 112 formed in the second coupling part 110 of the detachable pad 100, and a second fastening member 130 inserted by passing through the through-hole 112. In the present embodiment, like the first fastening member 22, a plurality of through-holes 112 and a plurality of second fastening members 130 are formed in the second coupling part 110, and each of the plurality of through-holes 112 and the plurality of second fastening members 130 corresponds to one of the plurality of first fastening members 22.

(17) Particularly, the through-hole 112 may be formed in the form of a slot in the second coupling part 110 of the detachable pad 100, and the second fastening member 130 may be moved relative to the through-hole 112 in a longitudinal direction of the through-hole 112 within the through-hole 112. That is, in a case where the detachable pad 100 is moved downward in a state in which the detachable pad 100 is coupled to the helmet main body 12, the through-hole 112 is moved along with the detachable pad 100, and accordingly, the second fastening member 130 may be moved relative to the through-hole 112 toward the other side of the through-hole 112 and located at the other side of the through-hole 112.

(18) The second fastening member 130 has at least a part protruding toward the outside of the detachable pad 100 in a state in which the second fastening member 130 is located at one side of the through-hole 112, and is inserted toward the inside of the detachable pad 100 in a case where the second fastening member 130 is moved relative to the through-hole 112 toward the other side of the through-hole 112.

(19) Accordingly, the second fastening member 130 is inserted into the fastening hole 23 of the first fastening member 22 in the state in which the second fastening member 130 is located at one side of the through-hole 112, thus coupling the helmet main body 12 and the detachable pad 100, and in a state in which the second fastening member 130 is moved relative to the through-hole 112 toward the other side of the through-hole 112, the second fastening member 130 is separated from the fastening hole 23, thus separating the detachable pad 100 from the helmet main body 12.

(20) Hereinafter, such a coupling structure will be described in more detail.

(21) As illustrated in FIG. 5, in the present embodiment, the second fastening member 130 includes an insertion part 132, a connecting part 134, and a deviation preventing part 136. As illustrated in FIG. 6, the second fastening member 130 is inserted into the through-hole 112, and in this case, a movement guide 114 configured to guide movement of the second fastening member 130 relative to the through-hole 112 is formed at a circumference of the through-hole 112.

(22) The insertion part 132 is disposed in a direction facing the first fastening unit of the helmet main body 12, i.e., the inner surface of the helmet main body 12, with respect to the through-hole 112. The deviation preventing part 136 is disposed in a direction opposite the insertion part 132 with respect to the through-hole 112, and the connecting part 134 is disposed in the form of connecting the insertion part 132 and the deviation preventing part 136.

(23) In this case, in the present embodiment, the insertion part 132 and the deviation preventing part 136 are formed to have a width wider than that of the through-hole 112, the connecting part 134 is formed to have a width narrower than that of the through-hole 112, and the second fastening member 130 maintains a state in which the connecting part 134 is inserted into the through-hole 112 and locked.

(24) In the case of the present embodiment, as illustrated in FIG. 7, the movement guide 114 includes a first seating part 114a, an inclined part 114b, and a second seating part 114c.

(25) The inclined part 114b is formed to be inclined so that the second fastening member 130 is inserted into the inside of the detachable pad when the second fastening member 130 is moved relative to the through-hole 112 from one side to the other side of the through-hole 112.

(26) In this case, the first seating part 114a is formed at one side of the inclined part 114b to form a preset angle with the inclined part 114b, and the second seating part 114c is formed at the other side of the inclined part 114b to form a preset angle with the inclined part 114b.

(27) That is, the first seating part 114a and the second seating part 114c have relative positions different from each other to have a step, and the inclined part 114b serves to change the relative positions therebetween.

(28) Particularly, as illustrated in FIG. 8, the second fastening member 130 maintains a state in which the insertion part 132 protrudes toward the outside of the detachable pad 100 in a state in which the second fastening member 130 is located at one side of the through-hole 112, that is, the first seating part 114a of the movement guide 114, and accordingly, as illustrated in FIG. 9, the second fastening member 130 may be inserted into the fastening hole 23 of the first fastening member 22.

(29) Therefore, the helmet main body 12 and the detachable pad 100 are in a state of being coupled by the first fastening member 22 and the second fastening member 130.

(30) In such a state, in a case where the helmet main body 12 and the detachable pad 100 are moved in directions opposite from each other as illustrated in FIG. 10, the second fastening member 130 is moved relative to the through-hole 112 toward the other side of the through-hole 112 in a state in which the second fastening member 130 is coupled to the first fastening member 22 in accordance with movement of the detachable pad 100 as illustrated in FIGS. 11 and 12.

(31) In this process, the second fastening member 130 passes through the inclined part 114b of the movement guide 114, and since the deviation preventing part 136 of the second fastening member 130 has a width wider than that of the through-hole 112 as described above, the deviation preventing part 136 is moved relative to the inclined part 114b of the movement guide 114 along the inclined part 114b.

(32) Accordingly, the entire second fastening member 130 is moved relative to the inclined part 114b toward the second seating part 114c along the inclined part 114b so as to be inserted into the inside of the detachable pad 100, and the second fastening member 130 is forcibly removed from the fastening hole 23 of the first fastening member 22.

(33) As a result, as illustrated in FIG. 13, in a case where the helmet main body 10 and the detachable pad 110 are moved relative to each other in opposite directions, fastening between the first fastening member 22 and the second fastening member 130 may be released by the above-described process, and the helmet main body 10 and the detachable pad 110 may be completely separated from each other.

(34) That is, in the present disclosure, the first fastening member 22 and the second fastening member 130 may be separated from each other just by moving the helmet main body 10 and the detachable pad 110 relative to each other in opposite directions, and separate effort is not required.

(35) In the present embodiment, the first seating part 114a and the inclined part 114b and the inclined part 114b and the second seating part 114c are formed to have linear cross-sections and are formed to have predetermined angles therebetween. The reason for forming of the linear cross-sections and predetermined angles is to form a resistance spot for each section in the process in which the second fastening member 130 is moved relative to the through-hole 122 within the through-hole 122. That is, by ensuring that a predetermined load is applied in the process in which the second fastening member 130 performs relative movement between the first seating part 114a, the inclined part 114b, and the second seating part 114c of the movement guide 114, the first fastening member 22 and the second fastening member 130 may be prevented from being separated from each other due to an external force smaller than or equal to a reference external force.

(36) The first embodiment of the present disclosure has been described above, and other embodiments of the present disclosure will be described below.

(37) FIG. 14 is a view illustrating a structure of a movement guide 114 of a second fastening unit in a detachable pad fastening structure of a helmet according to a second embodiment of the present disclosure.

(38) In the case of the second embodiment of the present disclosure illustrated in FIG. 14, the movement guide 114 has the form in which only a first seating part 114a and an inclined part 114b are included, and the second seating part 114c in the first embodiment is omitted. Even in this case, the same advantageous effect as that of the first embodiment may be obtained.

(39) Further, the movement guide 114 may also be formed only with the inclined part 114b without the first seating part 114a.

(40) FIGS. 15 and 16 are views illustrating a detachable pad fastening structure of a helmet according to a third embodiment of the present disclosure.

(41) The third embodiment of the present disclosure illustrated in FIGS. 15 and 16 is different from the above-described embodiments in that any one of the second fastening units disposed in the detachable pad 100 is substituted with a third fastening unit.

(42) That is, in the present embodiment, in a case where the number of first fastening units is n, the number of second fastening units is n−1, and a third fastening member 140 of a third fastening unit is coupled to first fastening member 22 of the remaining first fastening unit that does not correspond to the n−1 second fastening units. Unlike the second fastening unit, a through-hole is not formed in the form of a slot in the third fastening unit, and therefore, unlike the second fastening member 130, the third fastening member 140 is formed so as not to be moved relative to the detachable pad 110.

(43) Accordingly, in the present embodiment, in a case where the helmet main body 10 and the detachable pad 110 are moved relative to each other in opposite directions, only the second fastening member 130 is removed and separated from the first fastening member 22, and the third fastening member 140 maintains a state of being coupled to the corresponding first fastening member 22 such that the detachable pad 100 is rotated with respect to the helmet main body 12 about the third fastening member 140.

(44) Although any one of the second fastening units is substituted with the third fastening unit in the present embodiment, since a lower opening of the helmet main body 12 is open by rotation of the detachable pad 100 as in the other embodiments described above, the helmet main body 12 may be smoothly removed from a head of a wearer.

(45) FIG. 17 is a view illustrating a detachable pad fastening structure of a helmet according to a fourth embodiment of the present disclosure.

(46) The fourth embodiment of the present disclosure illustrated in FIG. 17 is different from the above-described embodiments in that a second fastening unit located at an upper central portion from among the second fastening units disposed in the detachable pad 100 is substituted with a fourth fastening unit.

(47) In the present embodiment, unlike the second fastening unit in the above-described first embodiment or second embodiment, the fourth fastening unit is formed in the form of Velcro 150. Accordingly, a fastening unit in the form corresponding to the Velcro 150 may be disposed at the helmet main body side.

(48) The reason for substituting the second fastening unit located at the upper central portion from among the second fastening units with the fourth fastening unit as above in the present embodiment is to minimize a foreign body sensation of a wearer. That is, the upper central portion of the detachable pad 100 is a point at which a cheek portion of the wearer is adhered, and in a case where the second fastening unit is disposed at the point, there is a problem in that the user's skin may be pressed by the protruding second fastening member 130. Therefore, in the present embodiment, the second fastening unit at the upper central portion of the detachable pad 100 is substituted with the fourth fastening unit in the form of Velcro 150 to minimize discomfort of the wearer.

(49) Exemplary embodiments according to the present disclosure have been described above, and it is self-evident to those of ordinary skill in the art that, in addition to the above-described embodiments, the present disclosure may be embodied in other specific forms without departing from the gist or scope thereof. Thus, the above-described embodiments should be considered as illustrative instead of limitative, and accordingly, the present disclosure is not limited to the above description and may be modified within the scope of the attached claims and their equivalents.
