Description

  The present invention relates to a shield converter for a helmet that is interposed between a helmet and a shield attached to the helmet and enables the shield to freely open and close with respect to the helmet.

  FIG. 6 is a perspective view showing a conventional shield converter for a helmet.

  The conventional shield converter 100 has a semi-circular outer support member 101 and an inner support member 102, and the two support members 101, 102 are each provided with a rotating shaft 103 at both ends thereof. Are rotatably connected to each other. The shield converter 100 can move within a range between a position where the two support members 101 and 102 are open as shown in FIG. 6 and a position where the two support members 101 and 102 are closed so as to overlap each other. It is configured to be able to.

  Three hooks 104a, 104b, 104c are attached to the outer support member 101. Each of the hooks 104a, 104b, 104c has a detachable surface facing outward. A mounting hole is formed at a position where each hook of the outer support member 101 is mounted. Of these mounting holes, the hole to which the hook 104b at the center of the three hooks is mounted is a round hole (not shown), and the holes to which the hooks 104a and 104c on both left and right sides are mounted extend in the circumferential direction of the support member 101. It is the elongated hole 101a. Therefore, while the center hook 104b is fixed at the position shown in the figure, the hooks 104a and 104c on both left and right sides thereof can move along the elongated hole 101a within the length of the elongated hole 101a.

  Similarly, three hooks 105a, 105b, and 105c are attached to the inner support member 102 as converter-side attachment means. Each of the hooks 105a, 105b, and 105c has a detachable surface facing inward. Attachment holes are formed at positions on the inner support member 102 where the hooks are attached. Of these attachment holes, the hole to which the central hook 105b of the three hooks is attached is a round hole (not shown). The holes to which the hooks 105a and 105c on both left and right sides are attached are elongated holes 102a extending in the circumferential direction of the support member 101. Therefore, while the center hook 105b is fixed at the position shown in the figure, the hooks 105a and 105c on the left and right sides thereof can move along the elongated hole 102a within the length of the elongated hole 102a.

  FIG. 7 is a perspective view showing a helmet to which the shield converter shown in FIG. 6 is applied.

  The helmet shown in FIG. 7 is of a type in which a cap covers a part of the head other than the face, and is generally called “jet hel”. In this type of helmet 110, as shown in FIG. 7, hooks 111a, 111b, and 111c as helmet-side mounting means for connecting hooks (not shown) of a shield are provided on a forehead portion of the helmet 110. I have. This type of helmet 110 is usually used in the state shown in FIG. 7, or a state in which a shield (not shown) is directly attached to the helmet 110 by connecting a shield hook to the hooks 111a, 111b, 111c. Used in

  FIG. 8 is a perspective view showing a state where the shield converter shown in FIG. 6 is attached to the helmet shown in FIG.

  As shown in FIG. 8, the hooks of the shield 120 are connected to the hooks 104a, 104b, and 104c (see FIG. 6) of the support member 101 outside the shield converter 100, whereby the shield 120 is connected to the outside support member 101. Installed. At this time, the hooks 104a and 104c on both left and right sides of the outer support member 101 are moved and positioned in the elongated hole 101a of the support member 101 in accordance with the positions of the hooks on both right and left sides of the shield 120. On the other hand, the hooks 105a, 105b, and 105c (see FIG. 6) of the support member 102 inside the shield converter 100 are connected to the hooks 111a, 111b, and 111c (see FIG. 7) of the helmet 110. The inner support member 102 is attached to the helmet 110. At this time, the hooks 105a and 105c on both left and right sides of the inner support member 102 are moved and positioned in the elongated hole 102a of the support member 102 in accordance with the positions of the hooks 111a and 111c on both right and left sides of the helmet 110.

  The shield converter 100 is interposed between the helmet 110 and the shield 120 attached to the helmet 110 in this manner. As shown in FIG. 8, the open position where the shield 120 is raised and the two support members 101 and 102 overlap each other. The shield 120 can be freely opened and closed with respect to the helmet 110 between the closed position where the shield 120 is lowered to the position where the shield 120 is closed.

  By the way, the position of the hook 111b at the center of the helmet 110 is different depending on the helmet maker, and even the same maker is different depending on the type of the helmet. The position of the central hook 111b may be, for example, closer to the edge of the forehead portion of the helmet 110 than shown in FIG. 7, or may be further away from the edge of the forehead portion.

  The shield converter 100 shown in FIG. 6 can be attached to various helmets in which the position of the center hook 111b is slightly different. However, for a helmet where the center hook 111b is near the edge of the forehead, the inner support member 102 is attached to a position near the edge of the forehead of the helmet, and the position of the center hook 111b is near the edge of the forehead. For a helmet that is away from the helmet, the inner support member 102 will be attached at a position away from the edge of the forehead portion of the helmet.

  When the inner support member 102 is attached to a position near the edge of the forehead portion of the helmet, the position when the shield 120 attached to the helmet is lowered via the shield converter 100 is a position lower than the original position. turn into. In this case, not only is the design of the helmet used, but also the wind blows from the forehead of the helmet 110 during traveling, which may make the user uncomfortable. Further, when the shield 120 is raised, the shield 120 may not be sufficiently opened, and the shield 120 may obstruct the user's view.

  When the inner support member 102 is attached at a position away from the edge of the forehead of the helmet, the position when the shield 120 attached to the helmet is lowered via the shield converter 100 is higher than the original position. In the raised position. In this case as well, not only the design of the helmet when used is impaired, but also the wind may be entangled around the chin and cheeks during traveling, causing the user to feel uncomfortable.

  Therefore, the present invention provides a helmet shield that enables the shield to be placed at an optimum position even for various helmets in which the position of the helmet-side hook (helmet-side mounting means) from the edge of the forehead portion of the helmet is different. It is intended to provide a converter.

  In order to achieve the above object, the shield converter for a helmet of the present invention includes an inner support member attached to a helmet and an outer support attached to a shield, which are rotatably connected to each other around a rotation axis at both ends.

Can be adjusted by the adjusting means in accordance with the position of the helmet-side mounting means in the height direction of the inner support member.

  For example, for a helmet in which the position of the helmet-side mounting means is close to the edge of the forehead portion, the inner support member is attached to the helmet with the converter-side mounting means mounted below the height of the inner support member. By doing so, the inner support member can be mounted at a position somewhat away from the edge of the forehead portion of the helmet. Therefore, the position when the shield attached to the helmet is lowered via the shield converter can be brought closer to the original position, so that the design at the time of use of the helmet is not spoiled, and the wind is not Injection from the forehead can be suppressed. Further, since the shield can be sufficiently opened to its original position, it is possible to prevent the shield from hindering the user's view.

  On the other hand, for a helmet in which the position of the helmet-side mounting means is away from the edge of the forehead portion, the inner support member is mounted with the converter-side mounting means mounted above the height direction of the inner support member. By mounting on the helmet, the inner support member can be mounted at a position somewhat closer to the edge of the forehead portion of the helmet. Also in this case, the position when the shield attached to the helmet is lowered via the shield converter can be made closer to the original position, so that the design when using the helmet is not damaged, and the chin during running And wind around the cheeks.

  Further, the inner support member includes at least three converter-side mounting means arranged from one end to the other end of the inner support member, and the adjusting means includes the at least three The converter-side mounting means may be provided at a position where the converter-side mounting means other than the two converter-side mounting means closest to each of both ends of the inner support member is provided.

  The shield converter 10 of the present embodiment also has a semicircular outer support member 11 and an inner support member 12, respectively, like the conventional helmet shield converter shown in FIG. The two support members 11 and 12 are connected at both ends to be rotatable about a rotation shaft 13. In the present embodiment, these support members 11 and 12 are made of a resin material (for example, polycarbonate). A resin material, particularly polycarbonate, is an optimal material for the support members 11 and 12 of such a shield converter 10 that is frequently opened and closed because it is rich in elasticity and has high impact resistance. Further, by making the color transparent, it can be combined with a helmet and a shield of any color without a sense of incompatibility. Polycarbonate, even a general-purpose grade, has high transparency, and in this regard, it can be said that polycarbonate is the most suitable material for the support members 11 and 12 of the shield converter 10.

  The shield converter 10 has a range between a position where the two support members 11 and 12 are opened as shown in FIG. 1 and a position where the two support members 11 and 12 are closed so as to overlap each other as shown in FIG. It is configured to be able to move within. Further, the outer surface of the inner support member 12 and the inner surface of the outer support member 11 at the connection portions at both ends of the two support members 11 and 12 radially extend around the rotation shaft 13. A ratchet (not shown) composed of a plurality of grooves is provided, and when the outer support member 11 and the inner support member 12 are connected as shown, each ratchet is provided on each of the support members 11, 12. Ratchets are interlocking with each other. Therefore, the shield converter 10 of the present embodiment can hold the shield (not shown) at any position in the range between the open position shown in FIG. 1 and the closed position shown in FIG. 2 by the ratchet. Has become. As described above, the ratchet in the present embodiment functions as a position holding unit for holding the mutual positions of the inner support member 12 and the outer support member 11.

  Also, at least a part of the surface of the inner support member 12 facing the helmet, particularly the connecting portion between the both ends of the inner support member 12 and the outer support member 11, is a pad made of, for example, urethane foam or the like as a buffer means. 16 are provided. These pads 16 prevent the shield converter 10 from rubbing against the helmet and damaging the helmet when the shield converter 10 is attached to the helmet (see FIG. 8). It is preferable that an adhesive seal is provided on a surface of the pad 16 that contacts the helmet. In this case, when the shield converter 10 is attached to the helmet, the shield converter 10 is fixed to the helmet even at the pad 16 portion. Opening and closing can be performed more smoothly.

  A round hole (not shown) to which the center hook 14b of the outer support member 11 is attached, an elongated hole 11a to which the hooks 14a and 14c on both left and right sides of the outer support member 11 are attached, and an attachment to the outer support member 11 are provided. The configuration of the hooks 14a, 14b, and 14c to be used, the configuration of the elongated hole 12a to which the hooks 15a and 15c on the left and right sides of the inner support member 12 are attached, and the configuration of the hooks 15a, 15b, and 15c that are attached to the inner support member 12 are as follows. 6 is the same as the conventional shield converter shown in FIG.

  Next, a cross-sectional structure of each of the support members 11 and 12 will be described mainly with reference to FIG.

  FIG. 3A is a cross-sectional view taken along line AA of the outer support member 11 shown in FIG. A locking portion 11 b protruding from the inner wall surface of the outer support member 11 is provided above the inner wall surface of the outer support member 11. As shown in FIG. 1, in the present embodiment, two hooks 11 b are provided on both left and right sides of the hook 14 b attached to the center of the outer support member 11.

  FIG. 3B is a cross-sectional view taken along line BB of the inner support member 12 shown in FIG.

I have.

  FIG. 3C is a cross-sectional view taken along line CC of the shield converter 10 in a state where the two support members 11 and 12 are closed as shown in FIG. When the two support members 11 and 12 are closed (the shield is lowered), the locking portion 11b of the outer support member 11 is locked in the locking groove 12b of the inner support member 12. When the locking portion 11b is locked in the locking groove 12b, the user can feel a click, so that the user can know that the shield has been completely lowered. Further, since a certain amount of force is required to release the locking portion 11b from the locked state in the locking groove 12b and open the shield converter 10, the shield loses the wind pressure during traveling and is inadvertently lifted. Can be prevented.

  Further, when the outer support member 11 is lowered in the direction of the arrow shown in the drawing until the locking portion 11b is locked in the locking groove 12b, when the momentum is applied, the locking portion 11b is Abuts on a stopper 12c provided immediately below the locking groove 12b. Therefore, the outer support member 11 does not rotate below the inner support member 12 beyond the position shown in FIG.

As shown in FIG. 4, a portion of the inner support member 12 to which the center hook 15 b (see FIG. 1 and the like) is attached is provided at the center of the inner support member 12 in the height direction (the direction of the arrow in FIG. 4). Two mounting holes 12d ₁ and 12d ₂ are formed as adjusting means for enabling the height of the hook 15b to be adjusted. These two mounting holes 12d ₁ and 12d ₂ are arranged in the height direction of the inner support member 12. Central hook 15b is selectively attached to one of these mounting holes 12d _1, 12d _2.

  Referring again to FIG. 7, as described above, the position of the helmet 110, especially the central hook 111b, differs depending on the helmet manufacturer, and furthermore, even with the same manufacturer, the helmet 110 differs. For example, the position of the center hook 111b may be closer to the edge of the forehead portion of the helmet 110 than the position shown in FIG. 7, or may be further away from the edge of the forehead portion.

In contrast, the shield converter 10 of this embodiment, with respect to the helmet near the position of the center of the hook 111b is on the edge of the forehead portion, a central hook 15b into the mounting holes 12d ₁ of the lower side (see FIG. 1) By mounting the helmet in the mounted state, the inner support member 12 can be mounted at a position somewhat away from the edge of the forehead portion of the helmet. Therefore, the position when the shield attached to the helmet is lowered via the shield converter 10 can be brought closer to the original position, so that the design at the time of use of the helmet is not spoiled, It is possible to suppress blowing from the forehead portion. Further, since the shield can be sufficiently opened to its original position, it is possible to prevent the shield from hindering the user's view.

The shield converter 10 of this embodiment, with respect to the helmet position of the center of the hook 111b is away from the edge of the forehead portion, the upper side of the mounting hole 12d ₂ fitted with a central hook 15b (see FIG. 1) By mounting the helmet on the helmet in the upright position, the inner support member 12 can be mounted at a position somewhat closer to the edge of the forehead portion of the helmet. Also in this case, the position when the shield attached to the helmet is lowered via the shield converter 10 can be brought closer to the original position, so that the design when using the helmet is not spoiled, The wind can be suppressed from being wound around the chin and cheeks.

  FIG. 5 is a partially enlarged view corresponding to FIG. 4 and showing a modification of the inner support member shown in FIG. 4 and the like.
