Description

Chin protector positioning assembly and helmet with same

Technical Field

The present invention relates to a chin guard positioning unit and a helmet having the same, and more particularly, to a chin guard positioning unit and a helmet having the same, which can determine a position of a chin guard for protecting a user's chin.

Background

A motorcycle helmet is used to protect the head and face of a user riding a motorcycle. Various types of helmets for motorcycles are marketed in order to take various factors into consideration, such as the purpose, the use, and the preference of the user. For the purpose of specific explanation, various kinds of helmets are simply listed, and among them, a Full-Face helmet (Full-Face Halmet) is a helmet in which the head and Face of a driver are all wrapped. A Half helmet (Half-Face Halmet) is a helmet in the shape of a head part only as a light-weight helmet. An Open-Face (Open-Face hammet) is a helmet in a shape of wrapping a part of the head and Face and exposing a part of the chin, between a full helmet and a half helmet. The System helmet (System Halmet) is the same as a full helmet, wrapping the head and face in their entirety, but differs in the portion that can wrap the chin in an openable manner.

Recently, with a tendency toward pursuit of both safety and convenience, demand for system helmets is increasing, and thus various products are being introduced. Each product has a different mechanism to move the chin guard position to distinguish one from another. As one of the products, the chin guard switching device of the existing system helmet (korean patent laid-open publication No. 10-0659171, 2006.12.12) has problems in that it is difficult to manufacture and the failure rate is frequent in case of long-term use as a device implemented by using a rack-and-pinion mechanism. Further, the chin guard is activated only in the case where an external force is applied, and thus there is a problem in that the chin guard cannot be operated effectively in the case where the external force cannot be transmitted effectively, such as in the case of wearing a thick outer jacket.

Fig. 4 (a) is a front perspective view of a fixed body portion of a chin guard positioning assembly according to an embodiment of the present invention; fig. 4 (b) is a rear perspective view of a fixed body portion of the chin guard positioning unit according to the embodiment of the present invention.

Referring to fig. 4, the fixing body 1210 may include a fixing region 1211 and a stopper assembly 1212, the fixing region 1211 may provide a predetermined region in which the moving base 1100 may be installed, and the stopper assembly 1212 may restrict a movement of the moving connector 1120, which will be described later.

The fixing region 1211 has a plate shape and provides a predetermined region where the moving base portion 1100 can be mounted.

The fixing region 1211 may be coupled to the helmet main body 200.

For example, the fixing region 1211 has a plurality of holes, and the fixing region 1211 can be coupled to the helmet main body 200 by fastening means (bolts) penetrating through the plurality of holes.

The guide portion 1211a may pass through from one surface of the fixing region 1211 to the other surface of the fixing region 1211.

The guide portion 1211a may be inserted into a movement connection portion 1120 to be described later.

The moving connector 1120 is slidable on the guide 1211 a.

The guide 1211a may guide the movement connector 1120 and may move the movement connector 1120 along a path set in advance.

The movable connecting portion 1120 is movable only in a position within a range where the guide portion 1211a is formed. This feature can be expressed as the moving connection portion 1120 performs a position movement according to a path set in advance.

The guide portion 1211a may be formed in the fixing region 1211 in a lower direction with respect to a shaft insertion hole 1211g to be described later.

The guide portion 1211a may penetrate from one surface of the fixing body portion 1210 to the other surface, extend in one direction, and change a curvature radius.

Therefore, the area of the fixing region 1211 can be minimized.

The fixing body portion 1210 may further have a guide projection 1211b formed to project from the rear of the fixing area portion 1211 along the circumference of the guide portion 1211 a.

A second movement coupling portion 1120b, which will be described later, is installed behind the guide projection 1211b, and the second movement coupling portion 1120b is slidably coupled to the rear of the guide projection 1211 b.

The guide projection 1211b may form a predetermined space, and a pressing projection 1212a-3, which will be described later, may be disposed.

Specifically, the guide projection 1211b is not projected in a portion of the circumference of the guide portion 1211a, and a predetermined space in which the pressurizing projection 1212a-3 can be disposed may be formed.

The guide projection 1211b may prevent the fixed region 1211 from being broken due to the moving connection part 1120, and may perform a function of forming a predetermined space in which the pressing projection 1212a-3 may be disposed.

The guard guide 1211c may pass through the fixing area 1211 from one surface to the other surface of the fixing area 1211.

A movable insertion portion 1560 described later can be inserted into the guard guide 1211c.

The movable insertion part 1560 may slide on the guard guide 1211c.

The guard guide 1211c may guide the movable insertion part 1560 such that the movable insertion part 1560 moves in position according to a path set in advance.

The movable insertion part 1560 is movable only in position within a range where the guard guide 1211c is formed. This feature can be expressed as the movable insertion part 1560 performs a positional movement according to a path set in advance.

The guard guide 1211c may be formed in the fixing area 1211 in an upper direction with respect to a shaft insertion hole 1211g to be described later.

A first installation space S10 may be concavely formed around a lower side of one end portion of the guard guide 1211c.

In addition, the other end portion lower side circumference of the guard guide 1211c may be recessed to form a second mounting space S20 and a third mounting space S30, respectively.

Here, the second installation space S20 and the third installation space S30 may be spaced apart from each other.

A second installation space S20 and the third installation space S30 may be sequentially formed with respect to a direction toward the other end of the guard guide 1211c.

The moving insert part 1560 may be installed in the first to third installation spaces S10 to S30.

Accordingly, the guard part 400 may be temporarily fixed at a predetermined position.

Here, the temporary fixation means that the position is not moved when an external force equal to or less than a predetermined external force acts within an external force range in which no breakage occurs, but the position is moved when an external force exceeding the predetermined external force acts.

The fixing body portion 1210 may further include a first shielding guide projection 1211d formed to project from a rear surface of the fixing area 1211 to extend along an upper circumference of the shielding guide 1211c while being spaced from the shielding guide 1211c.

In addition, the fixing body portion 1210 may further have a second shielding guide projection 1211e formed to project from a rear surface of the fixing area portion 1211 along a lower circumference of the shielding guide 1211c.

The first guard guide projection 1211d may be spaced apart from the second guard guide projection 1211 e.

A movement rising portion 1540, which will be described later, may be disposed between the first guard guide projection 1211d and the second guard guide projection 1211 e.

Specifically, for example, the moving rising part 1540 may be slid by contacting the upper and lower surfaces of the moving rising part 1540 at the lower surface of the first shield guide projection 1211d and the upper surface of the second shield guide projection 1211 e.

The moving insert part 1560 is slidable on the upper surface of the second shield guide projection 1211 e.

The second shielding guide projection 1211e may support the moving insert part 1560, and may smoothly slide the moving insert part 1560.

The first guard guide projection 1211d and the guard guide projection 1211e may guide the moving ascent portion 1540 so that the moving ascent portion 1540 performs a position movement according to a path set in advance.

Here, the fact that the position is moved along the previously set path means that detailed description thereof is omitted insofar as it overlaps with the above description.

The fixing body portion 1210 may further have an open fixing portion 1213 formed to protrude from the rear of the fixing area portion 1211.

The open fixing portion 1213 may be connected to the first protective guide projection 1211 d.

The open fixing portion 1213 can provide a predetermined space in the inside direction, and a moving protrusion 1550, which will be described later, can be inserted into the provided predetermined space.

The fixing portion 1211f may penetrate from one surface of the fixing region 1211 to the other surface of the fixing region 1211.

The position of the fixed magnetic part 1300 may be fixed to the fixed attachment portion 1211 f.

Specifically, the area of the fixing attachment portion 1211f formed on one surface of the fixing region portion 1211 is larger than the area of the fixing attachment portion 1211f formed on the other surface of the fixing region portion 1211.

Accordingly, the fixed magnetic part 1300 is mounted in a fixable position at the fixed mounting part 1211 f.

The shaft insertion hole 1211g may penetrate from one surface of the fixing region 1211 to the other surface of the fixing region 1211.

The shaft insertion hole 1211g may be inserted into the rotation shaft 1220.

The fixing elastic portion 1212b may be formed of an elastic material.

For example, the fixing elastic portion 1212b may be a coil spring.

However, the type of the fixing elastic portion 1212b may be variously changed within a level that is obvious to a general skilled person.

One end of the fixed elastic portion 1212b is connected to the fixed region 1211, and the other end of the fixed elastic portion 1212b is connected to the pressing portion 1212a.

The pressing portion 1212a may have: a pressing pivot portion 1212a-1 connected to the fixing region 1211, a pressing extension portion 1212a-2 protruded from a side surface of the pressing pivot portion 1212a-1 in one direction, and a pressing protrusion portion 1212a-3 protruded from an upper surface of the pressing extension portion 1212 a-2.

The pressing pivot 1212a-1 is connected to the fixed region 1211 and is rotatable with respect to the fixed region 1211.

For example, a fastening tool (e.g., a bolt) may be coupled to the fixation area 1211 through the compression pivot portion 1212a-1, and the compression pivot portion 1212a-1 may be coupled to the fixation area 1211.

However, without being limited thereto, the method of connecting the pressing pivot portion 1212a-1 to the fixing area portion 1211 may be variously changed within a level apparent to a general skilled person.

The lower surface of the pressing extension 1212a-2 may contact the stationary elastic portion 1212 b.

The pressing protrusion 1212a-3 may protrude obliquely from an upper surface of the pressing extension 1212 a-2.

As an example, the pressing protrusions 1212a-3 may form a triangular shape.

However, without being limited thereto, the shape of the pressing protrusion 1212a-3 may be variously modified within a level apparent to a conventional skilled person.

Referring to fig. 5, the rotation shaft 1220 may include a shaft 1221 and a protrusion 1222, the shaft 1221 may be connected to the movable body 1110, and may rotate on the fixed body 1210 when the movable body 1110 moves, and the protrusion 1222 may be formed to protrude in one direction of the shaft 1221.

The rotation shaft 1220 may further include a shaft fixing portion 1223, and the shaft fixing portion 1223 may restrict the shaft portion 1221 from moving in a direction opposite to a direction in which the shaft portion 1221 is inserted into the shaft insertion hole 1211g.

One end of the shaft 1221 may be connected to the moving base portion 1100. In addition, the protrusion 1222 may be formed to protrude from the other end of the shaft 1221.

The shaft portion 1221 may have a first shaft portion 1221a mounted at the rear of the fixing region 1211 and a second shaft portion 1221b formed to protrude in one direction from the upper surface of the first shaft portion 1221 a.

The first shaft portion 1221a may be a circular plate shape having a predetermined thickness.

However, without being limited thereto, the shape of the first shaft portion 1221a may be variously modified within a level that is obvious to a conventional skilled person.

The first shaft portion 1221a may contact the rear of the fixed area portion 1211.

The protrusion 1222 may be connected to the first shaft portion 1221a to protrude in one direction from a portion of a side of the first shaft portion 1221 a.

A part of the side surface of the first shaft portion 1221a may be recessed, and the shaft fixing portion 1223 may be connected to the recessed portion.

The shaft fixing portion 1223 may be formed in a hook shape and may be brought into contact with an inner surface of the shaft insertion hole 1211g.

The second shaft portion 1221b and the first shaft portion 1221a may form a predetermined step difference.

Therefore, the upper surface of the first shaft portion 1221a, from which the second shaft portion 1221b does not protrude, may contact the lower surface of the fixing area 1211.

The second shaft portion 1221b is insertable into the shaft insertion hole 1211g.

The second shaft 1221b may be connected to the moving body 1110.

At least a part of the side surface of the rotation shaft 1220 may be formed as a flat surface, and the movable body 1110 may be slid.

As a specific example, a portion of the side surface of the second shaft portion 1221b may form a plane, and the remaining portion may form a circular arc.

The sides of the second shaft portion 1221b may form two planes.

In this case, the two planes can be balanced with one another.

The side surface of the second shaft portion 1221b forming a circular arc may contact the inner surface of the shaft insertion hole 1211g, and thus the rotation shaft portion 1220 rotates while being connected to the fixed region portion 1211.

Specifically, fig. 6 (a) is a front perspective view of the moving base part; fig. 6 (b) is a rear perspective view of the moving base portion.

As a specific example, the movable body 1110 may be characterized in that a rod portion 1111 penetrating from one surface of the movable body 1110 to the other surface is formed, and the rotating shaft 1220 may be inserted.

The lever portion 1111 may be formed to extend in one direction, and the rotating shaft portion 1220 may be slid when the moving body 1110 is moved.

The moving contact 1520 may be formed to extend in one direction from one side surface of the other end of the moving extension 1530.

The separation distance between the moving contact 1520 and the shield connection 1510 may be gradually reduced as the distance from the moving extension 1530 increases.

As a specific example, the moving extension 1530 and the moving contact 1520 may have an acute angle. In addition, the moving extension 1530 and the shield link 1510 may also have an acute angle.

The upper surface of the moving ascent portion 1540 may provide a predetermined area, and thus may contact the rear surface of the fixed area portion 1211.

The movement raising unit 1540 can guide the guard moving unit 1500 and move the guard moving unit 1500 along a predetermined path.

Specifically, fig. 8 (a) is a front perspective view of a chin guard positioning assembly according to an embodiment of the present invention. Fig. 8 (b) is a rear combined perspective view of a chin guard positioning assembly according to an embodiment of the present invention.

Referring to fig. 4 to 8, the rotation shaft portion 1220 may be connected to the moving body portion 1110 by being inserted into the shaft insertion hole 1211g.

As a specific example, the first shaft portion 1221a may be installed at the rear of the fixing area portion 1211, and the second shaft portion 1221b may be inserted into the rod portion 1111 through the shaft insertion hole 1211g.

The first moving magnetic part 1410 may be disposed in the first moving mounting part 1112a, and the second moving magnetic part 1420 may be disposed in the second moving mounting part 1112 b.

The projection 1222 may be located at a rear surface side of the fixing region 1211.

The first moving coupling portion 1120a is coupled to a rear surface of the moving body portion 1110, and the second moving coupling portion 1120b may be mounted on a rear surface of the guide protrusion 1222.

The movable connector 1120 prevents the movable body 1110 from being detached from the fixed region 1211.

The guard moving part 1500 may be disposed on the rear surface side of the fixed area 1211.

That is, the guard moving part 1500 and the fixed area 1211 may be disposed to face each other with the fixed area 1211 as a reference.

The protective connecting portion 1510 can contact the upper surface of the upper end of the fixing region 1211.

Fig. 9 is a diagram showing a state where a shield part provided in a helmet according to an embodiment of the present invention is raised.

Referring to fig. 1 and 9, the protector 400 is movable in position on the helmet body 200.

Fig. 1 may be a view illustrating a state in which the guard part 400 can protect the face of a user.

At this time, the guard 400 may contact the chin guard 300 as a protection position.

At this time, the position of the guard moving part 1500 may be referred to as a front position.

In the case where the protection moving part 1500 is in the front position, the protection part 400 can protect the face of the user.

Fig. 9 may be a diagram illustrating a state in which the guard part 400 cannot protect the face of the user.

At this time, the guard 400 may be spaced apart from the chin guard 300 as a protection position.

At this time, the position of the guard moving part 1500 may be referred to as a rear position.

If the protection moving part 1500 is located at the rear position, the protection part 400 cannot protect the face of the user.

Hereinafter, the operation of chin guard positioning assembly 1000 in accordance with the positional displacement of chin guard 300 will be described in detail.

The guard moving part 1500 is movable by rotating from a front position to a rear position.

The guard moving part 1500 is movable by rotating from a rear position to a front position.

Accordingly, the guard portion 400 can also be moved in position.

First, the guard moving section 1500 will be described in the rear position, describing the process of moving the chin guard 300 from the protecting position to the open position.

Hereinafter, reference numerals may refer to fig. 1 to 9.

Fig. 10 and 11 are views for explaining a process in which the chin guard moves from the protection position to the open position when the guard moving part provided in the helmet according to the embodiment of the present invention is in the rear position; fig. 12 and 13 are views for explaining the operation of the chin guard positioning assembly in the process shown in fig. 10 and 11; fig. 14 and 15 are diagrams for explaining an operation process of the chin guard positioning unit in the process shown in fig. 10 and 11.

Specifically, fig. 12 (a) and 14 (a) are diagrams showing the position of the chin guard positioning unit in the case where the chin guard and the guard are in the position of fig. 10 (a).

Fig. 12 (b) and 14 (b) are diagrams showing the positions of the chin guard positioning unit in the case where the chin guard and the guard are in the positions shown in fig. 10 (b).

Fig. 13 (a) and 15 (a) are diagrams showing the positions of the chin guard positioning unit in the case where the chin guard and the guard are at the positions shown in fig. 11 (a).

Fig. 13 (b) and 15 (b) are diagrams showing the positions of the chin guard positioning unit in the case where the chin guard and the guard are in the positions shown in fig. 11 (b).

Fig. 13 (c) and 15 (c) are diagrams showing the positions of the chin guard positioning unit in the case where the chin guard and the guard are at the positions of fig. 11 (c).

Fig. 10 (a), 12 (a) and 14 (a) may be diagrams showing the chin guard 300 in the protecting position.

In the case where the chin guard 300 is in the protection position, the chin guard 300 may be directly combined with the helmet main body portion 200.

For direct joining of the chin guard 300 and the helmet main body 200, although not shown in detail, various fastening means may be employed within the level that is obvious to a person skilled in the art of system helmets.

With the shield moving part 1500 in the rear position, the moving protrusion 1550 may be inserted into a space provided by the open fixing part 1213.

In addition, the movable insertion part 1560 may be disposed in the first installation space S10.

The movable resilient part 1570 may press the movable insertion part 1560 such that the movable insertion part 1560 is closely attached to the upper surface of the second guard guide projection 1211e constituting the first installation space S10.

Referring to fig. 10 (b), 12 (b) and 14 (b), when the chin guard 300 and the helmet body 200 are unfastened, the chin guard 300 is rotatable in the open position direction at the protecting position.

This may be that the chin guard 300 is rotated in an upper direction by the attractive force of the fixed magnetic part 1300 and the first moving magnetic part 1410.

The moving magnetic part 1400 may have a first moving magnetic part 1410, and the first moving magnetic part 1410 magnetically interacts with the fixed magnetic part 1300 when the moving base part 1100 is in the first position.

Here, the moving body 1110 may be rotated in an upper direction by the position movement of the chin guard 300, and accordingly, the rotation shaft 1220 may also be rotated, and the second moving connector 1120b may also be slid on the guide projection 1211 b.

Fig. 10 (b), 12 (b), and 14 (b) may be views in which the base section 1100 is moved to the first position.

The first position may be a position closer to the position of the moving base part 1100 in the case where the chin guard 300 is in the protection position than the position of the moving base part 1100 in the case where the chin guard 300 is in the open position.

At this time, the attractive force between the fixed magnetic part 1300 and the first moving magnetic part 1410 may be the maximum attractive force.

Referring to fig. 11 (a), 13 (a) and 15 (a), the moving body 1110 is slidable on the rotation shaft 1220 to move corresponding to the position of the moving link 1120, and when the moving base 1100 is moved from the first position to the second position, the distance between the rotation shaft 1220 and the moving link 1120 can be changed.

Specifically, in a case where the chin guard 300 continues to move to the open position side, the second moving coupling portion 1120b may slide on the guide projection 1211 b.

Here, since the curvature radius of the guide portion 1211a continuously varies, the distance between the second movement connecting portion 1120b and the rotation shaft portion 1220 may be changed.

Accordingly, the rotation shaft portion 1220 may slide on the rod portion 1111.

As an example, in a case where the moving base portion 1100 is at the first position, the rotation shaft portion 1220 may contact one end portion of the rod portion 1111.

When the chin guard 300 is located at the open position from the protecting position, the rotary shaft portion 1220 can slide on the rod portion 1111 in a direction from one end of the rod portion 1111 to the other end of the rod portion 1111.

In the case where the chin guard 300 is positionally moved from the state shown in fig. 10 (b) to the state shown in fig. 11 (a), the interaction between the first moving magnetic part 1410 and the fixed magnetic part 1300 may gradually become weak.

Here, the interaction may mean an attractive force due to magnetism.

In the case where the chin guard 300 continues to move in the open position direction in the state shown in fig. 11 (a), the second moving magnetic part 1420 and the fixed magnetic part 1300 may interact with each other.

Fig. 11 (b), 13 (b), and 15 (b) may be diagrams in a case where the base unit 1100 is moved to the second position.

The second position may be a position closer to the position of the moving base part 1100 in the case where the chin guard 300 is in the open position than the position of the moving base part 1100 in the case where the chin guard 300 is in the protection position.

The moving magnetic part 1400 may have a second moving magnetic part 1420, the second moving magnetic part 1420 being spaced apart from the first moving magnetic part 1410 to allow the moving base part 1100 to magnetically interact with the fixed magnetic part 1300 in a second position.

The first moving magnetic part 1410 may be disposed to face the second moving magnetic part 1420 with reference to the rod part 1111.

When the moving base part 1100 moves from the first position to the second position, the attractive force with the fixed magnetic part 1300 and the first moving magnetic part 1410 is gradually reduced at the beginning, and then the attractive force with the fixed magnetic part 1300 and the second moving magnetic part 1420 is gradually increased.

Accordingly, even if the external force applied to the chin guard 300 by the user is small in the section in which the attractive force with the fixed magnetic part 1300 and the second moving magnetic part 1420 gradually increases, the chin guard 300 can be rotated.

Generally, a helmet user wears a thick outer jacket, and thus the chin guard 300 is not conveniently moved to the open position, but the chin guard 300 in the protecting position is rotated only to a predetermined position and is also moved to a position close to the open position by the magnetic auto position by the positioning assembly of the chin guard 300 according to an embodiment of the present invention.

Referring to fig. 11 (b), 13 (b), and 15 (b), the attractive force of the fixed magnetic part 1300 and the second moving magnetic part 1420 may be a maximum attractive force.

The second moving connecting portion 1120b may contact the pressing protrusion 1212a-3.

The second moving connecting portion 1120b cannot be moved by the pressing projection 1212a-3.

Fig. 11 (c), 13 (c), and 15 (c) are views showing a state in which chin guard 300 is in the open position.

In the state of fig. 11 (b), the worker applies an external force to the chin guard 300, and the chin guard 300 is movable to the open position.

At this time, the fixing elastic portion 1212b contracts, and the second moving connecting portion 1120b located at one side of the pressing protrusion 1212a-3 can be positionally moved in the other side direction of the pressing protrusion 1212a-3.

In the case where the second moving coupling portion 1120b is located at the other side of the pressing protrusion 1212a-3, the fixing elastic portion 1212b may expand and may fix the position of the second moving coupling portion 1120b.

The chin guard 300 position may be secured in an open position by the stop assembly 1212.

With the chin guard 300 in the open position, the rotation shaft portion 1220 may contact the other end portion of the rod portion 1111.

In addition, the protrusion 1222 may be in contact with the moving extension 1530.

However, without being limited thereto, the protrusion 1222 may be spaced apart from the moving extension 1530.

As an example, with the chin guard 300 in the open position, the gap between the protrusion 1222 and the moving extension 1530 may be 1mm.

However, without being limited thereto, the length of the gap between the protrusion 1222 and the moving extension 1530 may be variously changed within a level that is apparent to a general skilled person in the case that the chin guard 300 is in the open position.

Since the spaced distance between the protrusion 1222 and the moving extension 1530 prevents the vibration of the chin guard 300 from being transmitted to the guard 400.

In addition, the vibration of the protector 400 can be prevented from being transmitted to the chin guard 300.

The above description is made of the process of moving the chin guard 300 from the protecting position to the open position when the guard moving unit 1500 is in the rear position.

In the case where the guard moving part 1500 is at the front position, the movement of the chin guard 300 from the open position to the guard position is performed in the reverse direction of the above-described process, and thus a detailed description thereof will be omitted.

As an example, the process of moving the chin guard 300 from the protecting position to the open position when the guard moving part 1500 is in the rear position may be the processes of fig. 10 (a), 10 (b), 11 (a), 11 (b), and 11 (c) which are sequentially performed; in the case where the guard moving part 1500 is at the front position, the process of moving the chin guard 300 from the open position to the guard position may be performed in the order of fig. 11 (c), 11 (b), 11 (a), 10 (b), and 10 (a).

When the moving base part 1100 is positionally moved from the second position to the first position, the moving body part 1110 may slide on the rotation shaft part 1220 to move corresponding to the position of the movement coupling part 1120, thereby changing the distance between the rotation shaft part 1220 and the movement coupling part 1120.

Hereinafter, a process in which the guard moving part 1500 moves from the front position and the chin guard 300 moves from the open position to the guard position will be described.

Fig. 16 and 17 are views for explaining a process in which the chin guard moves from the open position to the protection position when the guard moving portion provided in the helmet according to the embodiment of the present invention is in the front position; fig. 18 and 19 are diagrams for explaining the operation of the chin guard positioning unit in the process shown in fig. 16 and 17.

The guard moving part 1500 is in contact with the rotary shaft part 1220, and when the movement base part 1100 is moved from the second position to the first position, the guard moving part 1500 is moved from the front position to the rear position by the rotation of the rotary shaft part 1220.

When the shield moving unit 1500 is in contact with the projection 1222 and the moving base unit 1100 is moved from the second position to the first position, the shield moving unit 1500 is moved from the front position to the rear position by the rotation of the projection 1222.

The moving contact 1520 may be disposed at a position interfering with a moving path of the protrusion 1222 when the moving base 1100 rotates, in a case where the protection moving part 1500 is at the front position.

Fig. 16 (a) and 18 (a) are views showing the guard moving part 1500 at the front position and the chin guard 300 at the open position.

In the case that the guard moving part 1500 is in the front position, the moving protrusion 1550 may be disposed in the third installation space S30.

In addition, the protrusion part 1222 and the moving contact part 1520 may contact each other in a case where the guard moving part 1500 is in a front position and the chin guard 300 is in an open position.

Since the position of the moving base unit 1100 is determined by the position of the chin guard 300, technical features related to the position of the moving base unit 1100 when the chin guard 300 is in the open position will not be described in a range overlapping with the above description.

Fig. 16 (b) and 18 (b) show a state where the moving base section 1100 is at the second position.

In the case where an external force is applied from the chin guard 300 in the open position to rotate the chin guard 300 in the guard position direction, the rotation shaft 1220 also rotates in the same direction.

The protrusion 1222 can push out the moving contact portion 1520 along with the rotation of the rotation shaft portion 1220, so that the guard moving portion 1500 is also rotated, and the moving insert portion 1560 can be positionally moved from the third installation space S30 to the second installation space S20.

As the guard moving part 1500 rotates, the guard moving part 1500 may also rotate from the rear position in the front position direction.

Referring to fig. 17 (a) and 19 (a), when the chin guard 300 continues to rotate in the guard position direction from the open position in the state where the movement base portion 1100 is at the second position, the rotation shaft portion 1220 also rotates, and the guard moving portion 1500 also continues to rotate by the rotation of the projection 1222.

Referring to fig. 17 (b) and 19 (b), in a case where the chin guard 300 continues to rotate from the open position to the protection position, the guard moving part 1500 may continue to rotate until the moving protrusion 1550 is inserted into the space provided by the open fixing part 1213.

If the shield moving part 1500 is located at the front position, the protrusion 1222 and the moving contact 1520 may not contact, and the shield moving part 1500 may not be rotated even if the protrusion 1222 rotates.

When the chin guard 300 is rotated from the open position in the protecting position direction in the state shown in fig. 17 (b) and 19 (b), the states shown in fig. 15 (a), 14 (b), and 14 (a) are sequentially performed, and detailed description thereof is omitted insofar as it overlaps with the above description.

Hereinafter, a process in which the guard moving part 1500 moves from the guard position to the open position and the chin guard 300 moves from the front position to the open position will be described.

The guard moving part 1500 is rotatable in a state of the front position to move the chin guard 300 at the guard position to the open position.

Accordingly, the moving base 1100 and the rotating shaft 1220 can also rotate together.

The chin guard 300 and the guard 400 may contact each other during the rotation of the chin guard 300 from the protecting position to the open position.

When the chin guard 300 and the guard 400 contact each other, the guard 400 may also rotate together with the rotation of the chin guard 300.

As the guard part 400 rotates, the guard moving part 1500 also rotates.

The third installation space S30 can rotate the guard moving part 1500 until the moving insert part 1560 is disposed in the first installation space S10.

Accordingly, the protection moving part 1500 may be located at a rear position.

If the guard moving part 1500 is located at the rear position, the guard part 400 is not rotated any more, and only the chin guard 300 may be rotated.

The chin guard 300 and the guard 400 in the rear position of the guard moving part 1500 may be rotated to the open position with a gap therebetween, and a detailed description thereof will be omitted to the extent that it overlaps with the above description.

A helmet of an embodiment of the present invention may comprise: a helmet body 200 providing a predetermined space into which a user's head can be inserted; a chin guard 300 movable from a protecting position where a user's chin is protected to an open position where the user's chin is not protected, or movable from the open position to the protecting position; a chin guard positioning assembly 1000 connecting the helmet main body 200 and the chin guard 300 to each other.

Here, the chin guard positioning assembly 1000 may have: a movement base part 1100 which provides a predetermined region to which the chin guard 300 can be attached and which performs a positional movement together with the chin guard 300 when the chin guard 300 performs the positional movement; a fixed base unit 1200 connected to the helmet body 200 and the movement base unit 1100, and serving as a reference for the movement of the movement base unit 1100; a fixed magnetic part 1300 fixed to the fixed base part 1200; and a movable magnetic part 1400 fixed to the movable base part 1100 by magnetic interaction with the fixed magnetic part 1300, so that the movable base part 1100 is fixed to a first position or a second position.

Hereinafter, a chin guard positioning assembly according to another embodiment of the present invention will be described.

However, detailed description is omitted insofar as it overlaps with the above description.

Referring to fig. 20, the rotating shaft 1220 may include a shaft 1221 and a protrusion 1222, the shaft 1221 may be connected to the movable body 1110 (see fig. 3), the rotating shaft may rotate on the fixed body 1210 (see fig. 3) when the movable body 1110 moves, and the protrusion 1222 may be formed to protrude in one direction of the shaft 1221.

The rotation shaft 1220 may further include a shaft fixing portion 1223, and the shaft fixing portion 1223 may restrict the shaft portion 1221 from moving in a direction opposite to a direction in which the shaft portion 1221 is inserted into the shaft insertion hole 1211g (see fig. 4).

Here, the shaft portion 1221 may have a first shaft portion 1221a and a second shaft portion 1221b, the first shaft portion 1221a being installed at the rear of the fixing region 1211, the second shaft portion 1221b being formed to protrude in one direction from the upper surface of the first shaft portion 1221 a.

The detailed description of the shaft 1221 and the shaft fixing portion 1223 may be omitted to the extent that the description is overlapped with the above description.

One side of the protrusion 1222 may form a circular arc.

Therefore, the protrusion 1222 can effectively (in stages) transmit the external force to the moving contact portion described later.

Fig. 21 and 22 are views for explaining an operation process of the chin guard positioning assembly according to another embodiment of the present invention in the process shown in fig. 16 and 17.

Referring to fig. 16 (a) and 21 (a), the protrusion 1222 and the moving contact 1520 may be spaced apart from each other in a case where the guard moving part is in a front position and the chin guard 300 is in an open position.

Referring to fig. 16 (b) and 21 (b), when an external force is applied to the chin guard 300 and the chin guard 300 in the open position is rotated in the protection position direction, the rotation shaft 1220 (see fig. 20) can be rotated in the same direction.

At this time, at least a portion of the rotation shaft 1220 contacts the moving contact 1520 while the rotation shaft 1220 rotates, so that the moving contact 1520 can be pushed out.

That is, a portion of the protrusion 1222 may contact the moving contact 1520.

Referring to fig. 17 (a) and 22 (a), when the chin guard 300 continues to rotate in the guard position direction from the open position with the movement base portion 1100 (see fig. 6) in the second position, the rotation shaft portion 1220 also rotates, and the guard moving portion 1500 also continues to rotate by the rotation of the projection 1222.

When the chin guard 300 is continuously rotated in the guard position direction from the open position in a state where a part of the protrusion 1222 is in contact with the moving contact portion 1520, the protrusion 1222 may be rotated by the rotation of the rotation shaft portion 1220.

Here, the shield moving part 1500 may also continue to rotate by the rotation of the protrusion 1222.

Since one side surface of the protrusion 1222 is formed in a circular arc shape, a portion of the protrusion 1222 contacting the moving contact 1520 may be different according to a degree of rotation of the rotation shaft 1220.

Accordingly, the protrusion 1222 may rotate while transmitting an external force to the moving contact 1520 in stages.

Since a portion of the protrusion 1222 is in stepped surface contact with the moving contact 1520, there is an advantage in that the external force is transferred in stages in contrast to the protrusion 1222 providing the external force to the moving contact 1520 at a time.

Referring to fig. 17 (b) and 22 (b), if the chin guard 300 continues to rotate from the open position in the direction of the guard position, the guard moving part rotates until the moving protrusion is inserted into the space provided by the open fixing part.

In the drawings, structures that are not related to or have little relevance to the technical idea of the present invention are simplified or omitted in order to clearly express the technical idea of the present invention.

The structural features of the present invention have been described above with reference to the embodiments of the present invention, but the present invention is not limited thereto, and various changes or modifications, which are obvious to those skilled in the art to which the present invention pertains, may be made within the spirit and scope of the present invention, and thus, the changes or modifications are within the scope of the claims.
