The present disclosure relates to a rotating body fixing means for a helmet.
In 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 conventional helmet includes a chin guard to protect the wearer's chin as disclosed in the patent literature of the related literatures described below.
Among the conventional helmets, a system helmet operates in a full face mode in which the chin guard closes the front side and an open face mode in which the chin guard opens the front side.
On the other hand, among the conventional helmets, a rotation helmet operates in a full face mode in which the chin guard closes the front side and an open face mode in which the chin guard moves to the rear side of the helmet to open the wearer's front side.
However, the conventional helmets do not have a means for stably fixing the chin guard in the full face mode and the open face mode, or even though there is such a fixing means, the fixing means is formed with a complicated structure in a ratchet, resulting in increased manufacturing cost.
The present disclosure is designed to solve the above-described problem, and an aspect of the present disclosure is directed to providing a rotating body fixing means for a helmet for fixing a rotating body in a simple and stable manner using a fixing portion that changes in extent to which it protrudes from a helmet body as it slides.

The features and advantages of the present disclosure will be apparent from the following detailed description in accordance with the accompanying drawings.
Prior to the description, it should be understood that the terms or words used in the specification and the appended claims should not be construed as limited to general and dictionary meanings, but rather interpreted based on the meanings and concepts corresponding to the technical spirit of the present disclosure on the basis of the principle that the inventor is allowed to define terms appropriately for the best explanation.
According to the present disclosure, it may be possible to fix the rotating body in a simple and stable manner using the fixing portion that changes in the extent to which it protrudes from the helmet body as it slides.
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
Basically, the helmet body 10 plays a role in protecting a wearer's head. The helmet body 10 may be made of a shock absorbing material. For example, 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. A pad may be present inside the absorber to improve a snug fit.
Additionally, the chin guard 20 plays a role in protecting the wearer's chin, and may be extended in such an arc shape as a whole that it is disposed at the front side of the wearer's chin. In this instance, the chin guard 20 may be rotatable with two ends rotatably coupled to two sides (for example, a ratchet 15) of the helmet body 10. For example, with the rotation of the chin guard 20, the chin guard 20 may be disposed at the front side of the wearer's chin (Full Face Mode) (see
Meanwhile, a shield 30 plays a role in opening and closing an open portion formed at the front side of the helmet body 10, and may be rotatably coupled to the two sides (for example, the ratchet 15) of the helmet body 10 and rotate with respect to the helmet body 10 to open and close the open portion.
In the rotating body fixing means for the helmet according to this embodiment, the rotating body may be, for example, the chin guard 20. Accordingly, the following description is made on the basis that the rotating body is the chin guard 20. However, the rotating body is not necessarily limited to the chin guard 20, and may be any configuration, for example, the shield 30 rotatably coupled to the helmet body 10.
The fixing portion 100 of the rotating body fixing means for the helmet according to this embodiment may be disposed on one side of the helmet body 10. For example, the fixing portion 100 may be disposed below the ratchet 15 of the helmet body 10, but is not necessarily limited thereto. Here, the fixing portion 100 is slidable with respect to the helmet body 10, and changes in the extent to which it protrudes from the helmet body 10 as it slides. When the fixing portion 100 protrudes from the helmet body 10, one surface (upper surface) of the fixing portion 100 contacts one side (lower side) of the chin guard 20, thereby stably fixing the chin guard 20 (see
Meanwhile, the helmet body 10 may be provided with a guide portion 200 to guide the fixing portion 100. Here, the guide portion 200 plays a role in guiding the fixing portion 100 with changes in extent to which the fixing portion 100 protrudes as it slides. As shown in
Although the foregoing description is made based on the fixing portion 100 having the protruding portion 110 and the guide portion 200 having the slit 250, the scope of protection of the present disclosure is not limited thereto, and the guide portion 200 may have the protruding portion 110 and the fixing portion 100 may have the slit 250. In this instance, the protruding portion 110 may extend from one side to the other side along the lengthwise direction of the guide portion 200, and extend in the outward direction of the helmet body 10 from one side to the other side.
Describing the guide portion 200 in more detail, the guide portion 200 may include a first guide member 210 and a second guide member 220 (see
Meanwhile, the guide portion 200 may have a protrusion portion 230 that extends along the lengthwise direction and protrudes toward the fixing portion 100 (see
Additionally, the fixing portion 100 may be provided with an elastic member 300 having elasticity, and when the elastic member 300 comes into contact with the guide portion 200, the elastic member 300 may compress the fixing portion 100 in the outward direction of the helmet body 10 due to its elasticity. For example, the elastic member 300 may be disposed in the recess portion 140 of the fixing portion 100, and when the elastic member 300 comes into contact with one surface (a surface facing the fixing portion 100, the protrusion portion 230) of the first guide member 210, the elastic member 300 may compress the fixing portion 100 in the outward direction of the helmet body 10 due to its elasticity. As described above, since the fixing portion 100 is compressed by the elastic member 300, when the fixing portion 100 slides from one side of the guide portion 200 to the other side, the fixing portion 100 may be always compressed in such a direction that it protrudes from the helmet body 10.
