Description

The present invention relates to improving the airtightness of a shield in a helmet.

The main part of a helmet worn by an occupant of a motorcycle or the like is a main cap body composed of an outer shell made of a hard synthetic resin and an inner liner made of a shock absorbing material such as a foam material. The main cap body of such a helmet has a substantially spherical shape, is open downward for the wearer to wear, and is provided with an opening window in the front to provide the wearer with a view. The opening window is usually provided with a transparent shield, and by closing the opening window, it is possible to prevent the inflow of wind and rainwater from the opening window while ensuring the wearer's field of vision. The shield is connected to a pair of rotating mechanisms protruding from both side surfaces of the main cap body, and is configured to be movable between a position where the opening window is closed and a position where the opening window is opened.

The so-called full-face type helmet has a chin guard under the opening window and covers the chin area of the wearer, so that the chin area can be protected from impacts and impacts even when the wearer falls, for example. In addition, the chin guard is configured to be movable upward with respect to the main cap body, and the full-face type safety, which is especially important when driving at high speed, and the so-called open face without a chin guard, which is desired when driving at low speed or when stopping, The so-called flip-up type helmet, which can be realized by switching between the feeling of openness of the mold, is also well known.

Patent Document 1 discloses a technique in which a gasket is inserted into a support frame of a helmet visor (corresponding to a shield of the present application) so that the visor is securely sealed when the visor is closed. Further, Patent Document 2 has a helmet sealing structure in which the gasket at the upper end of the visor is in close contact with the upper part of the opening window, and the lower end of the visor is in close contact with the sealing lip at the upper end of the jaw protector (corresponding to the chin guard of the present application). It has been disclosed. Further, in Patent Document 3, the shield screen (corresponding to the shield of the present application) is in close contact with the upper side of the window (corresponding to the opening window of the present application) and the upper end edge of the jaw protection plate (corresponding to the chin guard of the present application). , A technique for preventing air leakage is disclosed.

European Patent No. 1847192 U.S. Pat. No. 4,524,465 Japanese Unexamined Patent Publication No. 61-132604

In a helmet having a shield, since there is a gap between the shield and the main cap body, flooding inside the helmet becomes a problem especially in bad weather such as a storm or when running for a long time in rainy weather. In order to prevent flooding, rubber (hereinafter referred to as "window rubber") for sealing the gap between the shield and the opening window is provided on the periphery of the opening window to close the gap between the shield and the main cap body. It has been adopted. At this time, if water infiltrates inside the shield, the wearer's concentration may be reduced and safe driving may be hindered, so it is especially important to prevent water from entering the wearer's field of vision. Become. Specifically, by moving the positions of the left and right ends of the window rubber, which are prone to flooding, from the opening window, that is, by moving it to the rear of the helmet, even if it is flooded, it will be out of the wearer's view area as much as possible. It has been devised like this.

However, on both side surfaces of the main cap body, a pair of rotation mechanisms for connecting to both ends of the shield and allowing the shield to move in the vertical direction are provided. Therefore, in order to move the positions of the 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. On the other hand, from the viewpoint of reducing the weight of the helmet and ensuring safety, there is a demand for the structure of the rotating mechanism to be as simple as possible. As described above, there is a limit to the movement of the rotation mechanism itself to the rear of the helmet, and the position of the rotation mechanism on the side surface of the main cap body is actually limited to some extent. Therefore, it is difficult to make the flooded area completely out of the wearer's field of vision.

Further, since the rotating mechanism is composed of various members, the rotating mechanism has a shape slightly protruding from the outer surface of the main cap body when the helmet is viewed from above. Therefore, in the vicinity of the rotating mechanism, a sealing member thicker than the window rubber at the center of the opening window is required to fill the gap between the main cap body and the shield. Such a sealing member is integrally molded with the window rubber, or is configured as a separate member connected to the window rubber. However, exposing such a window rubber or a sealing member to the surface of the helmet has a problem that the aesthetic appearance in design is spoiled.

Especially in flip-up helmets where the chin guard can be moved relative to the cap body, these problems become more pronounced. In the flip-up type helmet, the chin guard is also connected to the rotation mechanism in order to make the chin guard movable in the vertical direction with respect to the main cap body. That is, since the thickness of the chin guard is added, the protrusion of the rotation mechanism becomes larger, and the sealing member for that purpose becomes bulkier. If the sealing member becomes bulky, the adhesion strength to the shield decreases, so that the inundation prevention function decreases. Therefore, in order to supplement the sealing member around the rotating mechanism, a further sealing member is added. However, there is a problem that it is difficult to add a sealing member so as not to hinder the movement of the shield or the chin guard.

In the flip-up type helmet, in order to overcome the above weaknesses, by moving both ends of the window rubber further to the rear of the helmet, even if water infiltrates, it goes out of the wearer's view area. A structure for escape is adopted. However, since a rotation mechanism for flipping up the chin guard and a rotation mechanism for raising and lowering the shield are provided on both sides of the main cap body, compared with a general full-face type helmet, It is more strongly restricted by the position of the rotating mechanism. Further, if the position of the rotating mechanism is set to the rear, the shield also needs to be extended to the rear, resulting in a large and heavy shield. As described above, the flip-up type helmet has a problem that the aesthetic appearance of the design is easily spoiled and it is difficult to surely eliminate the water leakage.

Further, in the technique described in Patent Document 1, the contact between the shield and the helmet is performed by providing a gasket between the shield and the helmet, but naturally, the gasket becomes larger than the shield and the helmet. Will be heavier. In addition, there may be a gap between the gasket and the helmet. Further, the techniques described in Patent Document 2 and Patent Document 3 can surely adhere the shield to the window rubber at the center of the opening window, but completely leak water from the periphery of the rotating mechanism to the inside of the helmet. There is a problem that it cannot be prevented.

The present invention has been made in view of the above-mentioned problems of the prior art, and has improved the airtightness between the main cap body and the shield in the helmet, and even in various types of helmets, the inside of the helmet in bad weather. It is intended to provide a helmet capable of preventing flooding.

In order to solve the above problems, the helmet in the present invention has a main cap body that is substantially spherical and has an opening window that opens at least forward to provide a view to the wearer, and projects on both sides of the main cap body. A shield that is connected to a pair of rotating mechanisms and can be moved to a closed position that is fixed to close the opening window and an open position that is fixed to open the opening window.
When the shield is in the closed position, the gap between the upper side of the shield and the upper side of the opening window of the main cap body is sealed from the vicinity of the rotation mechanism of one to the vicinity of the rotation mechanism of the other. With a sealing member,
The upper end portion of the shield is bent toward the main cap body at least on the upper side near the left and right ends of the seal member, and is in contact with the seal member when the shield is in the closed position. It is characterized by being.

According to the present invention, it is possible to obtain a helmet capable of improving the airtightness between the main cap body and the shield in a helmet and preventing water from entering the inside of the helmet even in various types of helmets in bad weather. ..

The helmet according to the present invention has a main cap body provided with an opening window that provides a view to an occupant of a motorcycle or the like to be worn, and a shield that is connected to the main cap body and opens and closes the opening window. Then, in order to prevent water from entering through the gap between the opening window and the shield even when the helmet is worn for a long time in bad weather such as a storm and rain, the opening window and the shield are used. The gap between them is sealed by a sealing member. At this time, even if water should enter the inside of the helmet, the left and right ends of the seal member are moved to the rear of the helmet as much as possible so that the water does not enter the wearer's field of view.

The shield is held in a pair of rotation mechanisms for opening and closing the shield provided on both side surfaces of the main cap body, and is rotated about a rotation axis substantially orthogonal to the side surface of the main cap body. A part called a shield base is built in. Therefore, the pair of rotation mechanisms protrude from the left and right side surfaces of the main cap body. In order to hold the shield with an appropriate strength, the thickness of the rotating mechanism is required to some extent, and the position of the rotating mechanism is also determined within a predetermined range.

Conventionally, the left and right ends of the seal member have been arranged closer to the front of the helmet than the rotation mechanism. Since the rotating mechanism has a predetermined thickness, it is necessary to raise the left and right ends of the seal member higher from the side surface of the main cap body as it is closer to the rotating mechanism. When the amount of start-up of the seal member is large, the adhesion strength to the shield is lowered, so that the inundation prevention function is lowered. Therefore, another sealing member was added to the left and right ends of the sealing member to compensate for the deterioration of the inundation prevention function.

However, if the left and right ends of the seal member are further moved rearward, it interferes with the opening / closing movement of the shield, so that another sealing member cannot be added. Therefore, in the present embodiment, instead of adding another sealing member to the left and right ends of the sealing member, the upper end of the shield is bent toward the main cap body. As a result, the degree of adhesion between the shield and the main cap body is increased, and the gap is eliminated. Further, since the air resistance at the upper end of the shield is reduced, it is possible to prevent water from entering the inside of the helmet, improve aerodynamic performance, and reduce wind noise.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a helmet according to an embodiment of the present invention when the shield is closed and the chin guard is underneath. As shown in FIG. 1, the helmet 1 according to the embodiment of the present invention is formed by connecting a substantially spherical main cap body 10 and a shield 20. The lower portion of the main cap body 10 is an opening opened for the wearer to insert and wear the head, and an opening window 11 is provided in front of the main cap body 10. The wearer can see the front through the opening window 11.

The shield 20 can be moved to a closed position fixed so as to close the opening window 11 and an open position fixed to open the opening window 11 by a pair of rotation mechanisms 12a and b. The shield 20 can be made of a transparent resin material such as polycarbonate.

Rotating mechanisms 12a and 12b are provided on both side surfaces of the main cap body 10. In FIG. 1, the rotation mechanism 12a on the left side surface is a shield base (not shown) that is connected to the shield 20 and rotates the shield 20 about a rotation axis substantially orthogonal to the left side surface of the main cap body 10. It has built-in parts. Although not shown, the rotation mechanism 12b is similarly provided on the right side surface of the main cap body. The rotating mechanisms 12a and 12b project from both sides of the main cap body 10 for built-in components.

A chin guard 13 is provided in front of the main cap body 10 and below the opening window 11. The chin guard 13 covers the wearer's chin area and, for example, protects the wearer's chin area from impacts and impacts during a fall. The chin guard 13 is formed separately from the main cap body 10, is connected to the rotation mechanisms 12a and 12b, rotates with respect to the main cap body 10, and has a first position fixed below the upper side 111 of the opening window. It is movably connected to a second position fixed above the upper side 111 of the opening window. The rotation axis of the chin guard 13 does not have to coincide with the rotation axis of the shield 20. When the rotation axis of the chin guard 13 does not match the rotation axis of the shield 20, the chin guard 13 can be configured by connecting to a component different from the shield base to which the shield 20 is connected.

FIG. 2 is a perspective view of the helmet of the embodiment of the present invention when the shield is open and the chin guard is down. Since the configuration 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, the description of each part will be omitted.

FIG. 3 is a perspective view of the helmet of the embodiment of the present invention when the shield is open and the chin guard is on top. Since the configuration 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 the chin guard 13 is in the upper position (second position), the description of each part will be omitted.

FIG. 4 is a schematic view showing the xx cross section of FIG. 1 in the helmet of the embodiment of the present invention when the shield is closed and the chin guard is underneath. The xx cross section is a substantially horizontal plane passing through the vicinity of the upper side 111 of the opening window.

As shown in FIGS. 1 to 4, the main cap body 10 is provided with a sealing member 14 that seals the gap between the main cap body 10 and the shield 20. The sealing member 14 is provided on the peripheral edge of the opening window 11 and seals the gap between the shield 20 and the opening window 11. The location where the seal member 14 is provided is the position of the main cap body 10 corresponding to the upper side of the shield 20 when the shield 20 is in the closed position, and is near the upper side 111 of the opening window 11. Further, the seal member 14 is provided so as to be hermetically sealed from the vicinity of the rotation mechanism 12a on the left side to the vicinity of the rotation mechanism 12b on the right side. Since the rotation mechanisms 12a and 12b project from both side surfaces of the main cap body 10 as described above, the vicinity of the left end 141a and the right end 141b of the seal member 14 is formed to have a larger thickness than the vicinity of the central portion. At this time, if the left end 141a and the right end 141b of the seal member 14 are configured to be on the rear side of the left and right ends of the opening window 11, a portion having a relatively high risk of inundation can be kept away from the occupant's field of view, which is preferable. be. The seal member 14 can be configured as an integral window rubber by an elastic material such as rubber, and can also be configured by a window rubber and a sealing member which are continuously formed by an elastic material such as rubber.

Cover members 15a and 15b are provided around the rear of the rotation mechanisms 12a and 12b of the main cap body 10, respectively. By providing the cover members 15a and 15b so as to be connected to the left end 141a and the right end 141b of the seal member 14, the gap between the main cap body 10 and the left and right rear portions of the shield 20 is closed to prevent water intrusion, and the rotation mechanism 12a is provided. And 12b can be protected from impact. The cover members 15a and 15b can be formed of resin or the like as separate members from the main cap body 10 and the shield 20. Further, the cover members 15a and 15b may be formed by projecting the main cap body 10 in the peripheral portion of the rotation mechanisms 12a and 12b. The cover members 15a and 15b are provided so as to cover at least the rear side of the rotation mechanisms 12a and 15b. In this way, the periphery of the rotating mechanism 12a and 12b is sealed by the sealing member 14 and the cover members 15a and 15b.

FIG. 5A is a left side view of the helmet of the embodiment of the present invention when the shield is closed and the chin guard is down. As shown in FIG. 5A, the cover member 15a is provided so as to cover the rear side of the rotation mechanism 12a. At this time, if the upper surface of the seal member 14 and the upper surface of the cover member 15a form a continuous surface, the shield 20 can also be formed of the continuous surface corresponding to this shape, so that there are few steps and the inundation prevention effect is enhanced. It is aesthetically pleasing and easy to manufacture, which is suitable.

FIG. 5B is a right side view of the helmet of the embodiment of the present invention when the chin guard is underneath. As shown in this figure, in this embodiment, the right cover member 15b is attached to the chin guard 13. Although not shown, the left cover member 15a is attached to the chin guard 13 in the same manner as the right cover member 15b. When the chin guard 13 is underneath, the upper end portion 151b of the cover member 15b and the right end portion 141b of the seal member 14 overlap each other. Although not shown, the upper end portion 151a of the left cover member 15a and the left end portion 141a of the seal member 14 overlap each other.

Further, as shown in FIGS. 5C and 5D, when the chin guard 13 is opened from the bottom to the top, the upper end portion 151b of the cover member 15b and the right end portion 141b of the seal member 14 are separated from each other, and the left cover member 15a is separated. The upper end portion 151a of the seal member 14 and the right end portion 141a of the seal member 14 are separated from each other. In FIGS. 5B to 5D, the shield 20 is not shown.

FIG. 6 is a schematic cross-sectional view of the helmet of the embodiment of the present invention when the p portion of FIG. 5A is cut in the front-rear direction. As shown in FIG. 6, a seal member 14 is provided in the vicinity of the upper side 111 of the opening window 11 of the main cap body 10. The shield 20 bends toward the main cap body 10 on the upper side, and abuts on the seal member 14 at the bent portion.

FIG. 7 is a schematic cross-sectional view of the helmet according to the embodiment of the present invention when the q portion of FIG. 5A is cut in the left-right direction. As shown in FIG. 7, the shield 20 is bent so as to approach the main cap body 10 on the upper side, and the bent portion abuts on the left end 141a of the seal member 14 provided on the main cap body 10.

In the present embodiment, the chin guard 13 is movably connected to a first position fixed below the opening window and a second position fixed above the opening window by a pair of rotation mechanisms. However, the configuration of the chin guard is not limited to this, and the chin guard 13 may be integrally molded with the main cap body 10 so as not to move. Further, a helmet without a chin guard 13 and consisting only of a main cap body 10 and a shield 20 may be used.

As described above, according to the present invention, the seal member is pressed and brought into close contact with each other by bending the shield. As a result, even in various types of helmets, it is possible to prevent water leakage into the inside of the helmet in bad weather, which is an effect that cannot be obtained by the prior art. Further, it is possible to obtain the effect of improving the aerodynamic performance and reducing the wind noise.
