Description

Helmet for forming air curtain

The present invention relates to a helmet worn when riding a bicycle or motorcycle, and more particularly, to a helmet having an air curtain that can protect a user by minimizing the influence of a headwind.

In general, a helmet means a device used to protect the head from impact, and is used to protect the user's head in various situations, such as riding a bicycle or motorcycle, climbing a rock or ice wall, and working at a construction site. .

In particular, helmets used when riding a bicycle or motorcycle include a full-face helmet that covers the entire head and face, an open-face helmet that exposes the face, a system helmet that covers the entire face while being able to open the face, and is called half-haired head. It is distinguished by a half-face helmet that covers the bay.

Among them, the half-face helmet is mainly used when riding a motorcycle that runs at a relatively low speed compared to other types of motorcycle, such as a scooter bike, or when riding a bicycle. Since these half-face helmets do not have a configuration to prevent the wind blowing towards the user's face when riding a bicycle or autoboy, the wind directly hits the eyes, causing tears, dust or insects entering the eyes or face. There are problems encountered with

Goggles, etc. are sometimes used to prevent this, but there may be difficulties in securing sufficient visibility when wearing goggles, and there are users who feel uncomfortable wearing goggles, so it is not a fundamental measure to solve the problem.

1. Republic of Korea Registered Utility Model No. 20-0218845 'Motorcycle helmet'

The present invention is to solve the above problems, and when riding a bicycle or motorcycle, the user does not use a separate protective tool to protect the eyes or face, but only by wearing a helmet that must be worn by the user from damage caused by the headwind. An object of the present invention is to provide a helmet in which an air curtain that can protect is formed.

The present invention for achieving the above object is a helmet in which an air curtain is formed, including a helmet body that is in the form of half hair and is put on the user's head, and the front part of the helmet body is recessed toward the rear; The air passage communicating with the wind receiving part includes an air curtain forming part formed downward.

In addition, the air flow path may be formed to be narrower than the outlet located at the lower side than the inlet located at the upper side.

In addition, the air flow path may be formed to be curved toward the front toward the lower portion while forming a cone shape.

In addition, the front portion of the helmet body further includes a cover for opening and closing the wind receiving unit, the cover can be opened so as to form a predetermined angle toward the upper end is hinged.

In addition, a plurality of blocking projections protruding downwardly in front of the air passage may be formed at the lower end of the air curtain forming part.

According to the present invention, since the headwind entering the wind receiving unit moves downward along the air flow path to form an air curtain in front of the user's face, a separate protective tool for protecting the eyes or face when riding a bicycle or motorcycle is not used. It is possible to protect the user from damage caused by the headwind without even having to do so, and in particular, it is possible to effectively prevent dust, insects, etc. carried by the headwind from entering the user's eyes.

In the present invention, to protect the user from damage caused by the headwind only by wearing a helmet that must be worn without using a separate protective tool to protect the eyes or face when riding a bicycle or motorcycle, a half-haired form is provided. and a helmet body to be put on the user's head, wherein the front part of the helmet body includes a wind receiving part recessed toward the rear, and an air curtain forming part in which an air passage communicating with the wind receiving part is formed downward. We propose a helmet with an air curtain, characterized in that the headwind entering the wind receiving unit moves downward along the air flow path to form an air curtain in front of the user's face.

The scope of the present invention is not limited to the embodiments described below, and various modifications may be made by those of ordinary skill in the art without departing from the technical gist of the present invention.

Hereinafter, the helmet on which the air curtain of the present invention is formed will be described in detail with reference to the accompanying FIGS. 1 to 10 .

As shown in FIG. 1, the helmet in which the present invention is formed with an air curtain is worn on a user's head when riding a bicycle or a motorcycle. It includes a helmet body (A) to be covered. However, although the helmet body (A) is shown in the drawings as forming a semi-haired shape, the rear side may be formed to further extend downward so as to cover all of the user's back head while forming a semi-haired shape.

The front part of the helmet body (A) includes a wind receiving part 100 and an air curtain forming part 200 as shown in FIG. 2 . The wind accommodating part 100 is recessed toward the rear, and a space for accommodating the headwind blowing to the user when the user wears the present invention and rides a bicycle or motorcycle is formed on the inside. At this time, the wind receiving unit 100 is preferably formed so that the inner surface is convex toward the rear so that the headwind entering the inside can easily move downward along the inner surface.

The air curtain forming unit 200 is formed on the lower side of the wind receiving unit 100 as shown in FIGS. 2 to 4 , and the air curtain forming unit 200 has an air passage communicating with the wind receiving unit 100 ( 210) is formed downward. That is, the inlet of the air flow path 210 is formed adjacent to the wind receiving unit 100, the outlet of the air flow path 210 is formed at the lower end of the helmet body (A), and the outlet is on the front side of the user's face. formed to be positioned.

Therefore, when the user wears the helmet body (A) on the head and rides a bicycle or motorcycle, the headwind enters the wind receiving unit 100 and then moves downward along the air flow path 210 and exits to the outside of the user. Forms an air curtain in front of the face. Accordingly, even if you do not use a separate protective tool to protect your eyes or face such as goggles or a mask when riding a motorcycle or riding a motorcycle, you can protect the user from damage caused by the headwind, such as dust and insects entering the user's eyes. have. In addition, in the present invention, since the speed of the headwind increases as the moving speed of the user increases, the strength of the air curtain formed also increases, thereby effectively protecting the user.

Specifically, the air flow path 210 is preferably formed to be narrower than the outlet located at the lower side than the inlet located at the upper side. That is, the air entering the wind receiving unit 100 moves from the relatively wide inlet to the relatively narrow outlet, and the movement speed is increased, so that the air curtain is more effectively formed in front of the user's face, so that the user can directly It is enough to block the headwind that blows towards the face.

The air flow path 210 may be formed, for example, in the shape of a cone whose diameter increases toward the upper side. At this time, the air curtain formed by exiting the air flow path 210 may be formed so that the front part of the helmet body (A) protrudes forward than a normal helmet to such an extent that the user's face angle does not have to be considered, but in this case, the helmet body ( As the weight of the front part of A) is excessively increased, problems such as the helmet body (A) flowing down to the front may occur. In order to form the air curtain, the air curtain is preferably formed in an oblique shape in consideration of the angle of the user's face.

Therefore, it is preferable that the air flow path 210 forming a cone shape is bent (curved) toward the front toward the lower portion as shown in FIGS. 2 to 4 . The air curtain formed through the air flow path 210 is formed in an oblique shape in front of the user's eyes and nose.

And the wind accommodating unit 100 may be formed to enter a single path in the crosswind as shown in FIG. 4 , as well as be formed to enter a plurality of paths as shown in FIG. 5 . . At this time, the wind receiving unit 100 may be provided with an inlet partition plate 110 in the form of a plate formed long in the left and right direction.

The inlet partition plate 110 may be formed in a variety of longitudinal cross-sections, but it is preferably formed such that the lower side is generally flat and the upper side forms a convex curve like an airplane wing so that the inflow of air can occur easily. In addition, a plurality of inflow partition plates 110 may be provided, and in this case, each inflow partition plate 110 is provided to be spaced apart from each other at a predetermined interval. And the inner surface of the wind receiving unit 100 that is in direct contact with the headwind and the inflow partition plate 110 are spaced apart, so that the air introduced up and down with respect to the inflow partition plate 110 is the inflow partition plate 110. It descends downward along the flow path formed at the rear of the , and enters the air flow path 210 .

On the other hand, the front portion of the helmet body (A) may further include a cover 300 for opening and closing the wind receiving unit 100, whereby the user can selectively form an air curtain. The cover 300 may be formed in various forms, and as an example, the upper end is hinged to the upper side of the wind receiving unit 100 as shown in FIGS. have. At this time, the cover 300 is configured to open at a predetermined angle toward the upper side as shown in FIG. 4 , so that the cross wind can be introduced into the wind receiving unit 100 along the inner surface of the open cover 300 . can do. As another example, the cover 300 may be configured to open and close the wind receiving unit 100 while sliding upward or downward as shown in FIG. 6 , and in this case, resistance due to the cover 300 is not generated. There are advantages.

And, as shown in FIG. 7 , a plurality of blocking protrusions 220 protruding downwardly in front of the air flow path 210 may be formed at the lower end of the air curtain forming unit 200 . The blocking protrusion 220 reduces the strength of the headwind blowing in from the lower side adjacent to the air curtain forming unit 200, so that the strength of the air curtain formed through the air flow path 210 blows directly toward the front of the user. It can prevent weakening due to collision with the headwind.

The blocking protrusion 220 is, for example, as shown in FIG. 8 , a first blocking projection 221 having a circular cross-section, a second blocking projection 222 having a U-shaped cross-section, and a third blocking projection having a V-shaped cross-section ( 223) may be included. A plurality of deterrence protrusions 220 may be configured to include all deterrence protrusions 220 having the same cross-section as well as deterrence protrusions 220 having different cross-sections.

9 and 10 show the arrangement of the blocking protrusions 220 formed in the left and right directions at the lower end of the air curtain forming unit 200 . As shown in FIG. 9 , the first blocking protrusions 221 having, for example, all circular cross-sections may be arranged to form one column or a plurality of columns, and when arranged to form a plurality of columns, intersect adjacent columns It is desirable to be arranged so that the headwind is effectively blocked. In addition, as shown in FIG. 10 , as another example, the first blocking protrusions 221 , the second blocking projections 222 , and the third blocking projections 223 having different cross-sections for each row may be arranged in a plurality of rows. .
