Description

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

  A helmet worn by a passenger such as a motorcycle mainly includes a main cap body including an outer shell made of a hard synthetic resin and an inner liner made of an impact absorbing material such as a foam material. The main cap body of such a helmet has a substantially spherical shape, and has a lower opening for wearing of the wearer, and an opening window in front of the wearer to provide a field of view. And the shield which has permeability | transmittance is normally distribute | arranged to the opening window, and inflow of the wind and rain water from an opening window can be prevented, ensuring a wearer's visual field by closing an opening window. The shield is connected to a pair of rotating mechanisms protruding on both side surfaces of the main cap body, and is configured to be movable between a position for closing the opening window and a position for opening the opening window.

  A so-called full-face helmet has a chin guard under the opening window and covers the wearer's jaw region, so that the jaw region can be protected from being hit or impacted even when the wearer falls. Furthermore, the chin guard is configured to be movable upward with respect to the main cap body, and is a full-face safety that is particularly important when traveling at high speeds, and the so-called open face that does not have a chin guard that is desired during low-speed traveling or when stopping. A so-called flip-up type helmet that can be realized by switching the feeling of opening of the mold is well known.

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

EP 1847192 US Pat. No. 4,524,465 JP 61-132604 A

  In a helmet having a shield, since there is a gap between the shield and the main cap body, inundation inside the helmet becomes a problem particularly during bad weather such as a storm or when traveling for a long time in rainy weather. In order to prevent inundation, a structure that seals the gap between the shield and main cap body by providing rubber (hereinafter referred to as “window rubber”) for sealing the gap between the shield and the opening window at the periphery of the opening window. It has been adopted. At this time, if inundation occurs inside the shield, it is particularly important to prevent the wearer from entering the field of view because the wearer's concentration may be reduced and hinder safe driving. Become. Specifically, the left and right ends of the window rubber, which is likely to be flooded, are moved away from the opening window, that is, moved to the rear of the helmet, so that it is outside the wearer's field of view as much as possible. Such ingenuity is given.

  However, a pair of rotating mechanisms are provided on both side surfaces of the main cap body so as to be connected to both ends of the shield so that the shield can be moved in the vertical direction. For this reason, 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 turning mechanism itself is moved to the rear of the helmet. On the other hand, there is a demand for making the structure of the rotation mechanism as simple as possible from the viewpoint of reducing the weight of the helmet and ensuring safety. Thus, 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 completely place the flooded portion outside the wearer's field of view.

  Furthermore, since the rotation mechanism is composed of various members, when the helmet is viewed from above, the rotation mechanism has a shape that protrudes somewhat from the outer surface of the main cap body. For this reason, in order to fill the gap between the main cap body and the shield around the rotation mechanism, a sealing member thicker than the window rubber at the center of the opening window is required. Such a sealing member is formed integrally with the window rubber or is configured as a separate member connected to the window rubber. However, exposing such a window rubber or sealing member to the helmet surface has the problem that the aesthetics of the design are impaired.

  In particular, in a flip-up type helmet in which the chin guard can be moved relative to the main cap body, these problems become more significant. 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 is further increased, and the sealing member for that purpose is also bulky. When the sealing member is bulky, the adhesion strength to the shield is lowered, so that the water immersion prevention function is lowered. Therefore, in order to supplement the sealing member around the rotation mechanism, a sealing member is further 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 and the chin guard.

  In the flip-up type helmet, in order to overcome the above weak points, both ends of the window rubber are moved further to the rear of the helmet, so that even if water has entered, it is outside the wearer's field of view. A structure for escaping 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 side surfaces of the main cap body, compared with a general full-face type helmet, The positional restriction of the rotation mechanism is more strongly received. Moreover, if the position of the rotation 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 lost, and it is difficult to surely eliminate water leakage.

  Moreover, although the technique described in the said patent document 1 has performed contact between a shield and a helmet by providing a gasket between a shield and a helmet, naturally a gasket becomes larger than a shield and a helmet Increases in weight. Moreover, there is a possibility that a gap is generated between the gasket and the helmet. Moreover, although the technique described in patent document 2 and patent document 3 can perform the contact | adherence with the shield and window rubber in the center of an opening window reliably, the leak from the periphery of a rotation mechanism to the inside of a helmet is completely completed. There is a problem that it cannot be prevented.

  The present invention has been made in view of the above-described problems of the prior art, and improves the sealing performance between the main cap body and the shield in the helmet. An object is to provide a helmet capable of preventing flooding.

In order to solve the above problems, a helmet according to the present invention is substantially spherical and has a main cap body that has an opening window that opens at least forward in order to provide a field of view to the wearer, and projects from both side surfaces of the main cap body. A shield that is connected to a pair of rotating mechanisms provided and is movable 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 one of the rotating mechanisms to the vicinity of the other rotating mechanism. And a sealing member
The upper end portion of the shield is bent toward the main cap body at least on the upper side in the vicinity of the left and right end portions of the seal member and contacts the seal member when the shield is in the closed position. It is characterized by being.

  A helmet according to the present invention includes a main cap body provided with an opening window that provides a field of view to an occupant such as a motorcycle to be worn, and a shield that is connected to the main cap body and opens and closes the opening window. In order to prevent water from entering through the gap between the opening window and the shield even when riding a motorcycle for a long time with a helmet in bad weather such as a storm, A gap between the two is sealed by a sealing member. At this time, even if water enters the inside of the helmet, the left and right ends of the seal member are moved as far back as possible to prevent the water from entering the wearer's field of view.

  Among a pair of turning mechanisms provided on both side surfaces of the main cap body for opening and closing the shield, the shield is held and rotated about a rotation axis substantially orthogonal to the side surface of the main cap body. There is a built-in component called a shield base. Therefore, the pair of rotating 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 rotation mechanism needs to have a certain thickness, and the position of the rotation mechanism is also determined within a predetermined range.

  Conventionally, the left and right ends of the seal member are disposed closer to the front of the helmet than the rotation mechanism. Since the rotation mechanism has a predetermined thickness, the closer the left and right ends of the seal member are to the rotation mechanism, the higher it is necessary to rise from the side surface of the main cap body. When the amount of start-up of the seal member is increased, the adhesion strength to the shield is reduced, so that the function of preventing flooding is lowered. Therefore, another sealing member is added to the left and right ends of the sealing member to compensate for the deterioration of the flood prevention function.

  However, if the left and right ends of the seal member are moved further rearward, it interferes with the opening and closing movement of the shield, so another sealing member cannot be added. Therefore, in this embodiment, instead of adding another sealing member to the left and right ends of the seal member, the upper side end portion of the shield is bent toward the main cap body. Thereby, the adhesion degree of the clearance gap between a shield and a main cap body increases, and a clearance gap is lose | eliminated. Furthermore, since the air resistance at the upper end of the shield is reduced, it is possible to prevent water from entering 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 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 cap body 10 and a shield 20. The lower portion of the main cap body 10 is an opening portion that is 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 visually recognize the front through the opening window 11.

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

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

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

  FIG. 2 is a perspective view of a helmet according to an embodiment of the present invention when the shield is open and the chin guard is below. 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 is omitted.

  FIG. 3 is a perspective view of a helmet according to an 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 in FIG. 1 except that the shield 20 is in the open position and the chin guard 13 is in the upper position (second position), description of each part is omitted.

  FIG. 4 is a schematic diagram 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 below. 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 seal member 14 that seals a gap between the main cap body 10 and the shield 20. The seal member 14 is provided on the periphery of the opening window 11 and seals the gap between the shield 20 and the opening window 11. The place 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. The seal member 14 is provided so as to be sealed from the vicinity of the left rotation mechanism 12a to the vicinity of the right rotation mechanism 12b. Since the rotating mechanisms 12a and 12b protrude 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 be thicker than the vicinity of the center 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 with a relatively high risk of inundation can be kept away from the field of view of the occupant. is there. 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 formed continuously by an elastic material such as rubber.

  Cover members 15a and 15b are provided at the rear periphery 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 blocked to prevent inundation, and the rotating mechanism 12a And 12b can be protected from impact. The cover members 15a and 15b can be formed of resin or the like as a separate member 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 sides of the rotation mechanisms 12a and 15b. Thus, the periphery of the rotation mechanisms 12a and 12b is sealed by the seal 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 below. 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 a continuous surface corresponding to this shape, so that the effect of preventing flooding is enhanced with fewer steps. It is also excellent in terms of aesthetics and easy to manufacture.

  FIG. 5B is a right side view of the helmet of the embodiment of the present invention when the chin guard is below. As shown in this drawing, in the present embodiment, the right cover member 15 b 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 at the bottom, the upper end portion 151b of the cover member 15b and the right end 141b of the seal member 14 are overlapped. Although not shown, the upper end portion 151a of the left cover member 15a and the left end 141a of the seal member 14 overlap each other.

  5C and 5D, the chin guard 13 is opened from the bottom upward, whereby the upper end portion 151b of the cover member 15b and the right end 141b of the seal member 14 are separated from each other and the left cover member 15a. The upper end 151a of the sealing member 14 and the right end 141a of the sealing member 14 are separated from each other. In addition, illustration of the shield 20 is abbreviate | omitted in FIG. 5B-FIG. 5D.

  FIG. 6 is a schematic cross-sectional view of the helmet according to the embodiment of the present invention when the portion p 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 is bent so as to approach the main cap body 10 on the upper side, and comes into contact with the seal member 14 at the bent portion.

  FIG. 7 is a schematic diagram of a cross section when the q portion of FIG. 5A in the helmet of the embodiment of the present invention 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 abuts against the left end 141 a of the seal member 14 provided on the main cap body 10 at the bent portion.

  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 formed integrally with the main cap body 10 so that it cannot move. Furthermore, the chin guard 13 may be omitted, and a helmet composed only of the main cap body 10 and the shield 20 may be used.

  As described above, according to the present invention, the shield is bent and the seal member is pressed and brought into close contact. Thereby, even in various types of helmets, there is an effect that cannot be obtained by the prior art, such as water leakage into the helmet inside during bad weather. Furthermore, the aerodynamic performance can be improved and wind noise can be reduced.

  As mentioned above, although embodiment of this invention has been described so far, embodiment of this invention is not limited to embodiment mentioned above. That is, other embodiments, additions, changes, deletions, and the like can be changed within the scope that can be conceived by those skilled in the art, and as long as the effects of the present invention are exhibited in any aspect, the scope of the present invention is included. It is included.
