Technical Field

The present invention relates to the improvement of the tightness of a protective shield in a helmet.

Background

A helmet to be worn by an occupant of a motorcycle or the like has a main helmet body having an outer shell made of a hard synthetic resin and an inner liner made of a collision absorbing material such as a foamed material as main parts, the main helmet body of the helmet has a substantially spherical shape, an open window opened downward to be worn by a wearer and an open window opened forward to provide a visual field to the wearer, and a shield having transparency is generally disposed in the open window to seal the open window, thereby preventing inflow of wind and rainwater from the open window while securing the visual field of the wearer.

A so-called full-face helmet covers a chin region of a wearer by having a jaw guard under an opening window, and thereby can protect the chin region from impact, collision, or the like even when the wearer falls, for example. Further, there is also known a so-called flip-top helmet in which a jaw protector is configured to be movable upward relative to a main helmet body, and safety of a full-face type, which is particularly important at the time of high-speed running, and a so-called open-face type, which is desired without a jaw protector at the time of low-speed running or stopping, can be switched.

Further, in U.S. Pat. No. 4524465, there is disclosed a sealing structure of a helmet in which a gasket at the upper end of the visor is closely fitted to the upper portion of an opening window and the lower end of the visor is closely fitted to a sealing lip at the upper end of a chin protector (corresponding to a chin guard of the present application), and in Japanese patent laid-open No. Sho 61-132604, there is disclosed a technique for preventing air leakage by closely fitting a shield (corresponding to a shield of the present application) to the upper edge of a window (corresponding to an opening window of the present application) and the upper edge of a chin guard (corresponding to a chin guard of the present application).

Disclosure of Invention

Problems to be solved by the invention

In order to prevent water intrusion, types of rubbers (hereinafter referred to as "window rubbers") for sealing the gap between the shield and the opening window are provided around the opening window to close the gap between the shield and the main helmet body.

However, pairs of rotation mechanisms connected to both ends of the shield and allowing the shield to move in the vertical direction are provided on both side surfaces of the main helmet body, and therefore, in order to move the positions of both left and right ends of the window rubber to the rear of the helmet, not only the shape of the shield is changed, but also the rotation mechanism itself is moved to the rear of the helmet.

Further, since the rotation mechanism is constituted by various members, when the helmet is viewed from above, the rotation mechanism has a shape that protrudes to a certain extent from the outer surface of the main helmet body, therefore, a seal member thicker than the window rubber at the center of the opening window is required around the rotation mechanism in order to fill up the gap between the main helmet body and the shield.

In particular, in a visor type helmet in which a jaw guard is relatively movable with respect to a main helmet body, these problems are more significant, and in the visor type helmet, the jaw guard is also connected to a rotation mechanism in order to have a structure in which the jaw guard is movable in a vertical direction with respect to the main helmet body, that is, since the thickness of the jaw guard is added, the protrusion of the rotation mechanism is increased and the sealing member is also increased, and therefore, the sealing strength with respect to the shield is decreased when the sealing member is increased and the soaking prevention function is prevented from being lowered, and therefore, the sealing member is added steps in order to compensate for the sealing member around the rotation mechanism, however, there is a problem that it is difficult to add the sealing member without hindering the movement of the shield and the jaw guard.

However, since the turning mechanism for turning up the chin and the turning mechanism for moving the shield up and down are provided on both side surfaces of the main helmet body, the position of the turning mechanism is more strongly restricted than in the case of the -type full-face helmet, and the shield also needs to be extended rearward when the turning mechanism is provided on the rear side, and as a result, the shield becomes large and heavy.

Further, the technology described in the specification of european patent No. 1847192 is to provide a washer between the shield and the helmet to bring the shield and the helmet into contact with each other, and it is obvious that the washer is larger than the shield and the weight of the helmet is increased, and there is a possibility that a gap is generated between the washer and the helmet, and the technology described in the specification of U.S. patent No. 452465 and japanese patent application laid-open No. 61-132604 is to reliably bring the shield and the window rubber into close contact with each other at the center of the opening window, but there is a problem of that water leakage from the periphery of the rotation mechanism into the helmet cannot be completely prevented.

The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide types of helmets capable of improving the sealing property between the main helmet body and the shield of the helmet and preventing water from entering the interior of the helmet in severe weather in various types of helmets.

Means for solving the problems

In order to solve the above problem, a helmet according to the present invention includes: a main helmet body having a substantially spherical shape and an open window opened at least in a front direction so as to provide a field of view to a wearer;

a shield connected to the pairs of rotating mechanisms protruding from both side surfaces of the main helmet body and movable to a closed position where the shield is fixed to close the opening window and an open position where the shield is fixed to open the opening window, and

a sealing member that seals a gap between an upper edge of the shield and an upper edge of the opening window of the main helmet body from the vicinity of rotation mechanisms to the vicinity of another rotation mechanisms when the shield is in the closed position,

an upper end portion of the shield is bent toward the main helmet body at least at an upper edge near left and right end portions of the seal member, and abuts against the seal member when the shield is in the closed position.

Effects of the invention

According to the present invention, a helmet in which the sealability between the main helmet body and the shield of the helmet is improved and water immersion into the interior of the helmet in severe weather can be prevented can be obtained.

Detailed Description

A helmet of the present invention includes a main helmet body provided with an opening window for providing a field of vision for a rider of a motorcycle or the like wearing the helmet, and a shield cover connected to the main helmet body for opening and closing the opening window, wherein a gap between the opening window and the shield cover is sealed by a sealing member so as to prevent water from entering from the gap between the opening window and the shield cover even when the helmet is worn in severe weather such as stormy weather and the motorcycle is used for a long time to travel, and at this time, even if water enters the helmet, the left and right ends of the sealing member are moved to the rear of the helmet as much as possible so as to prevent water from entering the field of vision of the rider.

Since the pair turning mechanisms for opening and closing the shield, which are provided on both side surfaces of the main helmet body, are provided with parts of a shield base which holds the shield and turns the shield around a turning axis substantially orthogonal to the side surface of the main helmet body, pair turning mechanisms protrude from the left and right side surfaces of the main helmet body, the thickness of the turning mechanism must be degrees in order to hold the shield with appropriate strength, and the position of the turning mechanism is limited within a predetermined range.

Conventionally, the left and right ends of the seal member are disposed forward of the helmet relative to the rotation mechanism. Since the rotating mechanism has a predetermined thickness, the sealing member needs to be raised higher from the side surface of the main helmet body as the left and right ends of the sealing member are closer to the rotating mechanism. When the rising amount of the seal member increases, the adhesion strength to the shield decreases, and therefore the function of preventing the shield from being immersed in water decreases. Therefore, additional sealing members are added to the left and right ends of the sealing member, thereby compensating for the reduction in the function of preventing flooding.

However, when the left and right ends of the seal member are moved backward in steps, the opening and closing movement of the shield is disturbed, and therefore, another seal member cannot be added.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Figure 1 is a perspective view of a helmet according to an embodiment of the invention when the shield is closed and the chin bar is located below. As shown in fig. 1, a helmet 1 according to an embodiment of the present invention is formed by connecting a substantially spherical main helmet body 10 and a shield 20. The lower portion of the main helmet body 10 is an opening that is opened for a wearer to wear the helmet by inserting the wearer's head, and an opening window 11 is provided in front of the main helmet body 10. The wearer can visually confirm the front through the opening window 11.

The hood 20 can be moved to a closed position where the rotating mechanisms 12a and 12b are fixed so as to close the opening window 11 and an open position where the opening window 11 is fixed so as to be open by , and the hood 20 can be made of a transparent resin material such as polycarbonate.

The turning mechanisms 12a and 12b are provided on both side surfaces of the main helmet body 10. In fig. 1, the turning mechanism 12a on the left side surface is connected to the hood 20, and incorporates a component such as a hood base (not shown) for turning the hood 20 about a turning axis substantially perpendicular to the left side surface of the main helmet body 10. Although not shown, the turning mechanism 12b is similarly provided on the right side surface of the main helmet body. The rotation mechanisms 12a and 12b protrude from both side surfaces of the main helmet body 10 by built-in members.

A jaw guard 13 is provided in front of the main helmet body 10 and below the opening window 11, the jaw guard 13 covers a chin region of a wearer, and protects the chin region of the wearer from impact, collision, or the like when the wearer falls, the jaw guard 13 is formed independently of the main helmet body 10, is connected to the turning mechanisms 12a and 12b, is turnable with respect to the main helmet body 10, and is connected to the turning mechanisms 12a and 12b so as to be movable to a position fixed below the opening window upper side 111 and a second position fixed above the opening window upper side 111, the rotation axis of the jaw guard 13 may not be aligned with the rotation axis of the shield 20, and in a case where the rotation axis of the jaw guard 13 is not aligned with the rotation axis of the shield 20, the jaw guard 13 may be connected to another member other than the shield base to which the shield 20 is connected.

Figure 2 is a perspective view of a helmet according to an embodiment of the invention when the shield is open and the chin bar is located below. The structure of each part of the helmet 1 is the same as that of fig. 1 except that the shield 20 is in the open position, and thus, the description of each part is omitted.

Cover members 15a and 15b are provided around the rear sides of the rotation mechanisms 12a and 12b of the main helmet body 10, respectively. By providing the cover members 15a and 15b so as to be coupled to the left end 141a and the right end 141b of the seal member 14, the gap between the main helmet body 10 and the left and right rear portions of the shield 20 can be closed, and the swivel mechanisms 12a and 12b can be protected from collision while preventing water from entering. The cover members 15a and 15b may be formed of resin or the like as members independent of the main helmet body 10 and the shield 20. The cover members 15a and 15b may be formed by projecting the main body 10 around the rotation mechanisms 12a and 12 b. The cover members 15a, 15b are provided to cover at least the rear sides of the rotating mechanisms 12a, 15 b. Thus, the peripheries of the rotating mechanisms 12a, 12b are sealed by the sealing member 14 and the lid members 15a, 15 b.
