Definitions

  • the present disclosure relates to a chin guard gap adjustment means for a helmet.
  • 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.
  • 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.
  • Patent Literature 1 KR10-2020-0120051 A
  • the present disclosure is designed to solve the above-described problem, and therefore an aspect of the present disclosure is directed to a chin guard gap adjustment means for a helmet, including an adjustment member to adjust a space between a chin guard and a helmet body, in order to reduce noise and drag by regulating the infiltration of air into the space between the chin guard and the helmet body while driving.
  • a chin guard gap adjustment means for a helmet is mounted in the helmet including a helmet body, and a chin guard which is rotatably coupled to the helmet body and is rotatable from a front side of a wearer's chin to a rear side or an upper side of the helmet body, and is coupled to the chin guard to adjust a space between the chin guard and the helmet body.
  • the chin guard gap adjustment means for the helmet includes an adjustment member rotatably coupled to the chin guard, and the adjustment member adjusts an angle between the adjustment member and the chin guard in response to a change of the space between the chin guard and the helmet body.
  • the chin guard gap adjustment means for the helmet further includes an elastic member to provide an elastic force to the adjustment member.
  • the chin guard gap adjustment means for the helmet includes a fastening member coupled to the chin guard, an adjustment member rotatably coupled to the fastening member, and an elastic member to provide the adjustment member with an elastic force in a direction in which an angle between the adjustment member and the fastening member increases.
  • the fastening member has a recessed portion in a thicknesswise direction, and when the adjustment member is disposed parallel to the fastening member, the adjustment member is inserted into the recessed portion.
  • the adjustment member rotates around a rotation axis in the recessed portion.
  • an exposed surface of the adjustment member contacts an inner wall of the recessed portion upon the rotation of the adjustment member in a direction in which an angle between the adjustment member and the fastening member increases.
  • the recessed portion has an open portion or an auxiliary recessed portion
  • the adjustment member includes a body which is inserted into the open portion or the auxiliary recessed portion, and an extended portion which is extended from the body, and comes into contact with a bottom surface of the recessed portion.
  • the helmet body has a fastening pin which protrudes to be coupled to the chin guard when the chin guard is disposed in front of the wearer's chin
  • the helmet body has a sloping portion which slopes such that it protrudes as it goes toward the fastening pin from above, and the adjustment member rotates in a direction in which the angle between the adjustment member and the fastening member decreases in contact with the sloping portion.
  • the adjustment member configured to adjust the space between the chin guard and the helmet body, it is possible to reduce noise and drag by regulating the infiltration of air into the space between the chin guard and the helmet body while driving.
  • the adjustment member rotates in contact with the sloping portion of the helmet body, it is possible to prevent interferences between the adjustment member and the fastening pin coupled to the chin guard.
  • FIGS. 1 and 2 are perspective views of a helmet including a chin guard gap adjustment means for a helmet according to an embodiment of the present disclosure.
  • a helmet body 10 plays a role in protecting a wearer's head.
  • the helmet body 10 may be made of a shock absorbing material.
  • the helmet body 10 may include an outer shell of hard synthetic resin and having high strength, and an absorber disposed in the outer shell, made of an expanded polystyrene (EPS) foam and having proper strength and elasticity.
  • EPS expanded polystyrene
  • a pad may be present inside the absorber to improve a snug fit.
  • 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.
  • 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.
  • 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 FIG.
  • the second predetermined position may refer to a position (Open Face Mode) when the chin guard 20 is disposed at the rear of the helmet body 10 (see FIG. 2 ).
  • the second predetermined position does not necessarily refer to the position when the chin guard 20 is disposed at the rear of the helmet body 10, and may refer to a position when the chin guard 20 is disposed above the helmet body 10 (for example, above a shield).
  • the chin guard gap adjustment means 100 for the helmet according to this embodiment is disposed between the helmet body 10 and the chin guard 20, and hereinafter, the chin guard gap adjustment means 100 for the helmet will be described in detail.

  • the adjustment member 110 may adjust the space between the chin guard 20 and the helmet body 10 in response to the change of the space between the chin guard 20 and the helmet body 10.
  • the other side of the chin guard 20 is not necessarily kept in contact with the outer surface of the helmet body 10, and may be spaced apart from the outer surface of the helmet body 10.
  • the adjustment member 110 may adjust (for example, close) the space, to prevent the infiltration of air, in order to reduce noise and drag.
  • the chin guard gap adjustment means 100 for the helmet may further include a fastening member 130 (see FIGS. 3 to 6 ).
  • the fastening member 130 may be coupled to the inner side of the chin guard 20, and the adjustment member 110 may be rotatably coupled to the fastening member 130.

As described above, when the adjustment member 110 is inserted into the recessed portion 135 of the fastening member 130, the adjustment member 110 may not protrude toward the helmet body 10.
  • the adjustment member 110 may rotate around a rotation axis in the recessed portion 135.
  • the recessed portion 135 may have an insertion hole 139 in two sidewalls, and the adjustment member 110 may have an insertion protrusion 119 at two ends, and when the insertion protrusions 119 of the adjustment member 110 are inserted into the insertion holes 139 of the recessed portion 135, the adjustment member 110 may rotate with respect to the insertion protrusion 119. That is, the insertion protrusions 119 may be the rotation axis of the adjustment member 110.
  • the adjustment member 110 since the rotation axis of the adjustment member 110 is disposed in the recessed portion 135, when the adjustment member 110 rotates in a direction in which the angle between the adjustment member 110 and the fastening member 130 increases, as a result, an exposed surface 110a of the adjustment member 110 contacts an inner wall 135a of the recessed portion 135 (see FIGS. 3 and 4 ). That is, the adjustment member 110 may rotate in a direction in which the angle between the adjustment member 110 and the fastening member 130 increases, and stop rotating when the exposed surface 110a of the adjustment member 110 contacts the inner wall 135a of the recessed portion 135. In the end, the adjustment member 110 may not rotate any more after rotating up to the predetermined angle (for example, perpendicular to the fastening member 130) between the adjustment member 110 and the fastening member 130.
