The present disclosure relates to a chin guard gap adjustment means for a helmet.
BACKGROUND ARTIn general, it is mandatory to wear a helmet while driving a two wheeled vehicle with high speed to protect the wearer's head. The helmet has a front open portion to ensure the wearer's frontal field of view. Additionally, the helmet may include a shield that can selectively open and close the open portion to keep out wind, dust, etc. while driving.
Meanwhile, the helmet according to the prior art includes a chin guard (a chin protector) to protect the wearer's chin as disclosed by the patent literature of the related literatures as described below. The chin guard (the chin protector) may be disposed at the rear of an outer shell after pivoting. In this case, an empty space is formed between the chin guard (the chin protector) and the outer shell. Accordingly, when air is introduced into the empty space between the chin guard (the chin protector) and the outer shell while driving, noise is generated and drag increases.

The objectives, particular advantages and new features of the present disclosure will be apparent from the following detailed description and exemplary embodiments in association with the accompanying drawings. In affixing the reference numbers to the elements of each drawing in the present disclosure, it should be noted that identical elements are given as identical numbers as possible although they are depicted in different drawings. Additionally, the terms such as “first”, “second” or the like are used to distinguish one element from another, and the elements are not limited by the terms. Hereinafter, in describing the present disclosure, when it is determined that a certain description of related known technology may unnecessarily obscure the subject matter of the present disclosure, the detailed description is omitted.
Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
As shown in
Additionally, a chin guard 20 plays a role in protecting the wearer's chin, and may be extended in an arc shape as a whole so that it is disposed in front of the wearer's chin. In this instance, the chin guard 20 is, at two ends, rotatably coupled to two sides (for example, a ratchet 30) of the helmet body 10, and thus is rotatable from a first predetermined position to a second predetermined position. For example, the first predetermined position may refer to a position (Full Face Mode) when the chin guard 20 is disposed in front of the wearer's chin (see
As shown in
The chin guard gap adjustment means 100 for the helmet may be coupled to the chin guard 20 to adjust the space between the chin guard 20 and the helmet body 10. As shown in
As described above, to allow the adjustment member 110 to rotate in response to the change of the space between the chin guard 20 and the helmet body 10, the chin guard gap adjustment means 100 for the helmet may include an elastic member 120 (see
As shown in
More specifically, the chin guard gap adjustment means 100 for the helmet may further include a fastening member 130 (see
Meanwhile, the adjustment member 110 may rotate around a rotation axis in the recessed portion 135. As shown in
In addition, the recessed portion 135 of the fastening member 130 may have an open portion 137 penetrating therethrough in the thicknesswise direction. In this instance, the adjustment member 110 may include a body 113 that is inserted into the open portion 137 of the recessed portion 135, and an extended portion 115 extended from two ends of the body 113 and having a smaller thickness than the body 113. Here, the extended portion 115 comes into contact with a bottom surface (an area without the open portion 137) of the recessed portion 135. As described above, since the body 113 of the adjustment member 110 is inserted into the open portion 137 of the recessed portion 135, it is possible to design the fastening member 130 with the minimum thickness while preventing the adjustment member 110 from protruding toward the helmet body 10. However, the recessed portion 135 of the fastening member 130 may not have the open portion 137 penetrating therethrough, and as shown in
Additionally, when the adjustment member 110 rotates in a direction in which the angle between the adjustment member 110 and the fastening member 130 decreases, as a result, the extended portion 115 of the adjustment member 110 comes into contact with the bottom surface of the recessed portion 135 (see
Meanwhile, the elastic member 120 is not limited to a particular type, but may be, for example, a torsion spring. As shown in
