A helmet assembly (H) according to one embodiment of the present invention is a device capable of separating a forehead and a helmet (helmet body (1)), and is referred to as ‘this device’ hereinafter for convenience of explanation.

Referring to FIGS. 1 and 2, the device (helmet assembly (H) (helmet assembly capable of separating the forehead and the helmet)) may include a helmet body (1), a side groove (9), a side fixing means (4), a wrapping member (2), and an adjusting means (3).

The helmet body (1) has a configuration corresponding to a known helmet on the market, and has a groove formed from the bottom to the top, into which the user's head is inserted, and is configured to protect the user's head.

Figures 1 and 2 are bottom views, showing the helmet body (1) viewed from the bottom. The helmet body (1) may have a number of holes formed therein for ventilation, for example.

Referring to Fig. 1, a pair of side grooves (9) may be formed by recessing from the inner side to the outer side of the helmet body (1) on both sides.

Here, the inner side refers to the groove side of the helmet body (1), and the outer side refers to the outer side of the helmet body (1), and the same terms will be applied in the following description.

The side fixing means (4) are installed by being inserted into each of a pair of side grooves (9), and a through hole is formed through which a wrapping member (2) described later passes, and the front end can face the temple.

The side fixing means (4) can be provided in pairs by being inserted into each of the pair of side grooves (9).

A pair of side fixing means (4) can be installed by being inserted into each side groove (9) and attached to the side groove (9) using a known adhesive or the like.

The above-mentioned side fixing means (4) may have a length in the front-back direction, and the side groove (9) may also have a length in the front-back direction.

A pair of side fixing means (4) can be installed by being inserted into a pair of side grooves (9) respectively and embedded in the helmet body (1).

The wrapping member (2) is arranged on the inside of the helmet body (1), the front side wraps around the user's forehead, and each of both sides can pass through the holes of a pair of side fixing means (4).

For example, the above wrapping member (2) can be formed of a resin material capable of elastic deformation.

Among the pair of side fixing means (4), one positioned on one side is referred to as the first connecting part (41), and the other positioned on the other side is referred to as the second connecting part (42).

Here, one side means the left side when the device is viewed on a flat surface (with the lower opening facing downward, i.e., based on the state of being worn by the user), and the other side means the right side based on the state of being worn, and the same will be applied in the following description.

The above wrapping member (2) has a shape like a string, and is connected to the helmet body (1) with the center facing the front side of the helmet body (1) and both sides penetrating the first connecting portion (41) and the second connecting portion (42), respectively, and both ends are gathered on the rear inner side of the helmet body (1) and can be connected to the helmet body (1) by being coupled to a pinion (33) of an adjustment means (3) described later.

The first connecting portion (41) and the second connecting portion (42) may each be formed of a resin material.

Here, the front refers to the direction in which the user wearing this device is looking, i.e., the left direction based on Fig. 1 and the downward direction based on Fig. 3, and the rear refers to the direction in which the user wearing this device is looking at the back of the head, i.e., the right direction based on Fig. 1 and the upward direction based on Fig. 3. The same applies in the following description.

Referring to FIGS. 3 and 4, the adjusting means (3) is provided (by way of example, attached) on the rear side of the helmet body (1) facing the back of the user's head, and is connected to each end of the wrapping member (2) so as to adjust the size of the through hole formed by the wrapping member (2). The through hole is a hole through which a person's head passes.

The above-mentioned control means (3) may include a first hole (31a) formed in one of the two ends of the wrapping member (2) (hereinafter, the first end), a second hole (32a) formed in the other of the two ends of the wrapping member (2) (hereinafter, the second end), a first rack (31b) protruding from one end of the wrapping member (2) toward the first hole (31a), and a second rack (32b) protruding from the other end of the wrapping member (2) toward the second hole (32b).

The first long hole (31a) and the second long hole (32a) may each be long holes having a longitudinal axis parallel to the longitudinal direction of the wrapping member (2), and the first rack (31b) and the second rack (32b) may each have a length parallel to the first long hole (31a) and the second long hole (32a).

At this time, the wrapping member (2) can form the through hole by overlapping both ends so that the first long hole (31a) and the second long hole (32a) are connected.

At this time, the control means (3) may include a pinion (33) that penetrates the first long hole (31a) and the second long hole (32a) and is gear-coupled with the first rack (31b) and the second rack (32b).

At this time, the first rack (31b) may be provided on the lower or upper side of the first end portion with respect to the first long hole (31a), and the second rack (32b) may be provided on the upper or lower side of the second end portion with respect to the second long hole (32a).

That is, when the first rack (31b) is provided on the lower side of the first end based on the first long hole (31a), the second rack (32b) can be provided on the upper side of the second end based on the second long hole (32a).

Accordingly, when the pinion (33) rotates in one direction, the first end and the second end are moved so that the overlapping portion increases, thereby reducing the size of the through hole, and conversely, when the pinion (33) rotates in the opposite direction, the first end and the second end are moved so that the overlapping portion decreases, thereby increasing the size of the through hole.

For example, as shown in FIGS. 3 and 4, when the first rack (31b) is provided on the lower side of the first end relative to the first long hole (31a) and the second rack (32b) is provided on the upper side of the second end relative to the second long hole (32a), when the pinion (33) rotates clockwise when viewed from the front, the two ends of the wrapping member (2) move to both sides so that the overlapping portion decreases (see [A] of FIG. 4), and when the pinion (33) rotates counterclockwise when viewed from the front, the two ends of the wrapping member (2) move so that the overlapping portion increases (see [B] of FIG. 3).

Accordingly, the size of the penetration hole of the covering member (2) can be adjusted so that users with various head sizes can wear the helmet body (1) without shaking.

At this time, as described above, since a pair of side fixing means (4) through which both sides of the wrapping member (2) are penetrated are each inserted and installed into the side grooves (9), when the penetration hole formed by the wrapping member (2) becomes smaller, the front side of the wrapping member (2) facing the forehead becomes further away from the front side of the helmet body (1), and thus the user's forehead and the front side of the helmet body (1) may be spaced apart.

Through this, the device can ensure smooth ventilation between the forehead and the helmet body (1), and can have a positive effect on hair loss by improving the health of the scalp in the forehead area.

In addition, since the front end of the side fixing means (4) faces the user's temple, the forehead and the helmet body (1) can be effectively separated.

Referring to Fig. 3, the adjusting means (3) may include a case (34). The case (34) may include a fixing portion (341) attached and fixed to the rear inner surface of the helmet body (1), an upper portion (342) extending forward from the upper end of the fixing portion (341), a lower portion (343) extending forward from the lower end of the fixing portion (341), and a through hole (344) formed in the fixing portion (341) and through which the pinion (33) passes.

In addition, the case (34) may include a front portion (345) that connects the front of the upper portion (342) of the Gandhi and the front of the lower portion (343) and is positioned in front of the through hole (344).

In addition, the control means (3) may include a cover (35) disposed in front of the case (34) and detachably coupled with the case (34).

The cover (35) and the case (34) can be detachably connected by a detachable connecting means (36) described later. The detachable connecting means (36) will be described in more detail in the description described later.

Fig. 5 is a drawing for explaining the cover part. Fig. 6 is a drawing for explaining the rear side of the case.

Referring to FIGS. 3 and 6, the control means (3) may include a tube (38) provided at the rear of the fixed part (341) and having a hollow space formed therein that communicates with the through hole (344).

In addition, referring to FIGS. 3, 5 and 6, the control means (3) may include a cover portion (39) including a rear plate (391), a peripheral portion (392) extending forward from the peripheral side of the rear plate (391), a groove portion (393) formed by the rear plate (391) and the peripheral portion (392) and into which the rear side of the body (38) is inserted and fitted, and a shaft member (394) protruding forward from the front of the rear plate (391) and axially coupled with the pinion (33) by penetrating the central hole of the pinion (33).

Accordingly, the pinion (33) may be restricted in forward movement by the front portion (345) while penetrating the through hole (344), and in backward movement by the cover portion (39). As described above, the pinion (33) may be restricted in forward and backward movement by penetrating the through hole (344) and penetrating the first long hole (31a) and the second long hole (32a) to be gear-coupled with the first rack (31b) and the second rack (32b).

The two ends of the above-mentioned wrapping member (2) are arranged between the front part (345) and the fixed part (341), so that forward and backward movement can be restricted in the same way, and as the cover part (39) rotates, the pinion (33) rotates, so that the first rack (31b) and the second rack (32b) can move.

For example, the helmet body (1) may include an insertion groove formed at the lower rear portion to allow the upper portion of the cover portion (39) to be inserted. The cover portion (39) may protrude downward through the insertion groove, and the user may rotate the pinion (33) by rotating the cover portion (39).

At this time, as described above, the fixing part (341) of the case (34) is attached and fixed to the rear inner side of the helmet body (1), and the pinion (33) is also fixed in position by passing through the through hole (344), so that both ends of the covering member (2) that is gear-coupled with the pinion (33) can be fixed to the rear inner side of the helmet body (1), thereby fixing the user's back of the head to be in contact with the rear inner side of the helmet body (1).

This device is worn for safety by a user using a means of transportation such as a bicycle or motorcycle. As the user moves forward on the means of transportation, he or she encounters wind blowing from the front to the rear. As described above, the front inner side of the helmet body (1) and the user's forehead are separated by the adjustment means (3) to form a separation space, so that the wind blowing from the front can easily move between the helmet body (1) and the head through the separation space.

Through this, the user can be prevented from taking off the helmet body (1) when the head becomes hot due to helmet use, and the scalp can be prevented from becoming hot and humid, thereby promoting scalp and hair health (e.g., suppressing scalp inflammation, sebum secretion, and bacterial growth).

Figure 7 is a drawing for explaining the front side of the case.

Referring to FIG. 3 and FIG. 7, the control means (3) may include a detachable coupling means (36) including an upper fitting groove (361) formed in the front end of the upper part (342) and a lower fitting groove (362) formed in the front end of the lower part (343).

In addition, the detachable coupling means (36) may include an upper fitting projection (363) that protrudes rearwardly to be inserted into the upper fitting groove (361) at the upper rear side of the cover (35), and a lower fitting projection (364) that protrudes rearwardly to be inserted into the lower fitting groove (362) at the lower rear side of the cover (35).

Through this, the cover (35) and the case (34) can be detachably combined, so that only the cover (35) that frequently comes into contact with the head can be replaced or maintained separately.

Referring to FIG. 3, the control means (3) may include a guide means (37) including a pair of first guide members (371) that protrude rearwardly from one rear side of the cover (35) and are spaced apart in the vertical direction so that the first end of the wrapping member (2) is disposed therebetween, and a pair of second guide members (372) that protrude rearwardly from the other rear side of the cover (35) and are spaced apart in the vertical direction so that the second end of the wrapping member (2) is disposed therebetween.

The above guide means (37) can be placed between the upper part (342) and the lower part (343).

The above guide means (37) is a means for guiding the first end and the second end to move without shaking.

Referring to FIG. 3, the detachable coupling means (36) may include a first coupling hole (365) formed in one of the uppermost pair of first guide members (371), and a second coupling hole (366) formed in one of the uppermost pair of second guide members (372).

Also, referring to FIG. 3 and FIG. 7, the detachable coupling means (36) may include a first coupling protrusion (367) that protrudes downwardly to penetrate the first coupling hole (365) from the lower portion of the upper portion (342), and a second coupling protrusion (368) that protrudes downwardly to penetrate the second coupling hole (366) from the lower portion of the upper portion (342).

Through this, the cover (35) can be prevented from moving forward while being coupled to the case (34).

The above case (34) can be formed of a plastic material capable of elastic deformation, and by elastically deforming the case (34), the first coupling protrusion (367) can be removed from the first coupling hole (365), and the second coupling protrusion (368) can be removed from the first coupling hole (365).

Meanwhile, referring to FIG. 6, the body (38) may include a catch (381) protruding from the outer surface.

At this time, referring to FIG. 5, the cover part (39) may include a catch (395) that protrudes from the rear side of the inner surface of the peripheral part (392) so that the catch (381) catches on it.

That is, when the cover part (39) moves forward and is inserted into the groove part (393) on the rear side of the pipe body (35), the catch projection (381) is positioned further forward than the catch step (395). Through this, the cover part (39) can be restricted from moving backward with respect to the pipe body (38) during normal times.

The cover part (39) and the body (38) above can be formed of a plastic material that can be elastically deformed, and when a large force is applied to move the cover part (39) to the rear, the catch projection (381) can be placed behind the catch step (395), and the cover part (39) and the body (38) can be separated from each other.

In this case, the pinion (33) can be removed from the first long hole (31a) and the second long hole (32a), and the two ends of the wrapping member (2) can be separated from each other, so that it can come out between the fixed part (341) and the front part (345). In other words, the case (34) and the wrapping member (2) can be separated from each other.

Referring to FIG. 3, the control means (3) may include a body provided at the rear of the pinion (33) and having a central hole formed that is in communication with the central hole of the pinion (33) and through which the shaft member (394) of the cover part (39) passes, and a plate (30) including a movable groove formed in the body.

At this time, referring to FIG. 5, the cover part (39) may include a movable projection (396) that protrudes forward from the rear plate (391) and is inserted into the movable groove.

Accordingly, when the cover part (39) rotates, the movable projection (396) is inserted into the movable groove to rotate the plate, thereby allowing the pinion (33) to rotate.

Meanwhile, although not shown, the cover part (39) may include a screw groove formed rearwardly in the rear plate (391), and a screw projection provided to protrude rearwardly to be inserted into the screw groove from the rear of the movable projection (396), but having screw threads on the outer surface to be screw-connected with the screw groove.

The above screw groove includes a peripheral surface extending forward from the rear and rear periphery and connecting with the front surface of the rear plate (391), and the peripheral surface is a groove provided with screw threads.

In this way, since the cover part (39) includes the screw groove and the screw projection, the movable projection (396) can be detachably connected to the rear plate (391), so that only the movable projection (396) that frequently comes into contact with the plate (30) and is likely to wear can be replaced separately.

Referring to FIG. 5, the cover portion (39) may include a number of anti-slip protrusions (397) protruding from the outer surface of each of the peripheral portion (392) and the rear plate (391).

Referring to FIGS. 1 to 3, the device may include a pad (5) positioned between the wrapping member (2) and the head, a loop (6) of a Velcro tape provided on a surface of the wrapping member (2) facing the pad (5), and a hook (7) of a Velcro tape provided on a surface of the pad (5) facing the wrapping member (2).

The above pad (5) can be made of a material capable of elastic deformation (for example, foam, etc.) and can protect the forehead of the head.

Since this device includes a loop (6) and a hook (7), the pad (5) can be detachably attached to the wrapping member (2).

Referring to FIGS. 1 and 2, a rear cushioning means (8) may be included that is attached (for example, by a bond or the like) to the front of the cover (35). The rear cushioning means (8) may also be formed of a material that is elastically deformable (for example, foam) to protect the back of the head from impact.

Referring to FIG. 3, the wrapping member (2) may include a main member (21) having an elongated shape, a first end side (22) attached to one of the two ends of the main member (21) and having the first long hole (31a) formed therein, and a second end side (23) attached to the other of the two ends of the main member (21) and having the second long hole (32a) formed therein.

The above first end side (22) may be the first end, and the above second end side (23) may be the second end.

At this time, the main member (21) may be formed of a material that is softer than the first end side (22) and the second end side (23). That is, each of the first end side (22) and the second end side (23) may be formed of a material that is softer than the main member (21).

For example, the first end side (22) and the second end side (23) may be formed of polycarbonate, and the main member (21) may be formed of nylon, but is not limited to the above materials.

The above main member (21) is formed of a flexible material as a part that can directly touch the head, such as the forehead, to improve the wearing comfort, and the first end side (22) and the second end side (23) can be formed of a softer material to minimize wear damage due to repeated contact with the case (34) and the cover (35).

Since the first end side (22) and the second end side (23) are each attached to the main member (21), if the first end side (22) and the second end side (23) are damaged, they can be separated from the main member (21) and the main member (21) can be reused.

Meanwhile, the wrapping member (2) may include a plurality of ventilation holes formed in the main member (21). At this time, the plurality of ventilation holes may be arranged at intervals along the length direction of the main member (21).

Although the embodiments of the present invention have been described with reference to the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features of the present invention. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
