Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a helmet with a visor, and particularly to an effective structure for preventing rattling of the visor.

[Prior Art] Some helmets for motorcycles are provided with a visor so as to cover the front part of the cap body at intervals. Such a visor is primarily intended to improve design. The visor is generally attached to the cap body by fastening both sides of the visor to the left and right sides of the cap body using screws.

[Problems to be Solved by the Invention] However, when a motorcycle or the like is running, if wind or gusts of wind hit the front of the helmet, the visor may be blown away. This may cause the visor to rattle and generate noise.

Therefore, the present invention aims to provide a helmet with a visor that solves the above problems.

[Means for Solving the Problems] In order to solve the above problems, the helmet with visor according to the present invention includes a visor that is provided to cover the front part of the cap body and supported on both sides of the helmet. and an inlet of a ventilation mechanism fixed to the front outer surface of the cap body, and a shutter for opening and closing this inlet, wherein the rear side of the visor has a predetermined position above the front outer surface of the cap body. The spaces overlap to form a ventilation passage that is open in the front-rear direction, and the front opening of this ventilation passage is formed between the front part of the visor and the front end of the cap body, and the ventilation passage is A rear open portion of the passage is formed by the front outer surface of the cap body and the rear end of the visor, and the shutter and a support member for guiding the shutter are provided on the front outer surface of the cap body in the center of the ventilation passage. and an engaging protrusion is provided between the support member and the visor to support the visor so as to engage the support member and the visor to maintain the rear open portion of the ventilation passage in an open state, and the engaging protrusion is provided in a position that cannot be seen from the outside of the visor.

[Operation of the device] The visor is supported by the engaging protrusions on both sides of the cap body and the front portion of the cap body so as to overlap with each other at a predetermined distance above the front outer surface of the cap body. Therefore, a ventilation passage that is open in the front-rear direction is formed between the visor and the front outer surface of the cap body, and the front opening of this ventilation passage is formed between the front part of the visor and the front end of the cap body. ,
The rear opening of the ventilation passage is formed by the front outer surface of the cap body and the rear end of the visor. Further, the rear open portion of the ventilation passage is maintained in an open state because the engaging protrusion supports the visor.

Therefore, even if driving wind or gusts of wind hit the front part of the cap body, these winds will blow through from the front opening through the ventilation passage and from the rear opening to the upper part of the cap body. As a result, the visor is less likely to be stirred, making it less likely to cause rattling noise.

Further, the engaging protrusion is located between the visor and the support member for guiding the shutter provided in the center of the ventilation passage, and is hidden behind the visor and is not visible from the outside of the visor, so that the appearance is not impaired.

Furthermore, the shutter can be opened and closed by inserting your finger into the front opening of the ventilation passage.

[Embodiment] FIGS. 1 to 3 show a helmet with a visor for a two-wheeled motor vehicle according to an embodiment of the present invention. FIG. 1 is a partially cutaway external view of the helmet with a visor, FIG. 2 is a side view of the same side view, and FIG. 3 is a perspective view of the shutter mechanism and the like. This visor-equipped helmet includes a visor 2 provided so as to cover the front of a cap body 1 at intervals. The cap body 1 is made of glass fiber reinforced plastic or the like, and both ends of a visor 2 are attached to the sides thereof with a pair of screws 3. Note that only the left side of the screw 3 is shown, and the right side is hidden in the shadow. The visor 2 is shaped like a bird's beak, and is provided primarily to improve the design. Also, between the visor 2 and the cap body 1 there is a ventilation passage 4 (second
(see figure) is formed, so that the traveling wind or gust of wind that hits the front part of the cap body 1 blows through this in the direction of the arrows in FIGS. 1 and 2. Therefore, the helmet is prevented from being tilted due to wind while driving. The front open part of the ventilation passage 4 is formed between the front part of the visor 2 and the front end of the cap body 1, and the rear open part of the ventilation passage 4 is formed between the front outer surface of the cap body 1 and the front end of the cap body 1. It is formed by the rear end.

Further, a ventilation mechanism 5 is provided on the ventilation path 4 on the front surface of the cap body 1. The details of the ventilation mechanism 5 will be explained later, but it is a mechanism that adjusts the amount of ventilation to cool the inside of the cap body 1.
It consists of a shutter 6 and an inlet base 7.
The inlet base 7 is a fixed member fixed on the front surface of the cap body 1, and the shutter 6 is a movable member slidably fitted thereto. Further, the shutter 6 is integrally molded with an operation knob 8 that extends downward. As shown in FIG. 2, the operating knob 8 has a non-slip 9 formed of a large number of horizontal grooves, and by pressing this with a fingertip F, the shutter 6 can be slid either up or down.
Therefore, the gap between the visor 2 and the cap body 1 in this portion is large enough to allow at least the fingertip F to enter. On the other hand, below the inlet base 7 and above the center of the front part of the cap body 1, a support member 10 is attached. At the center of the support member 10, a pair of left and right ribs 11 are formed that are raised in the vertical direction and guide both sides of the operating knob 8. Further, both ends of the support member 10 are bent to form a pair of cap-side engaging protrusions 12 that rise diagonally upward. Furthermore, each of these tips has an engaging recess 13.
are formed respectively.

On the other hand, as shown in FIG.
From the inner wall of visor 2 located at the position corresponding to
A pair of visor-side engaging protrusions 14 are formed that integrally protrude toward each engaging recess 13 . Each of these tip portions is fitted and locked into the engagement recess 13, respectively.

FIG. 3 shows an enlarged view of the ventilation mechanism 5 and the support member 10. The inlet base 7 is integrally formed with a mounting leg 15 extending toward the cap body 1 on its back surface, and is inserted into a mounting hole (not shown) that is previously formed through the cap body 1 in correspondence with the mounting leg 15. It is inserted and fixed inside the cap body 1 by heat caulking. Further, the inlet base 7 is formed with an inlet 16 which is an air intake port, and this fits into a through hole formed in advance in the cap body 1, and furthermore, a ventilation passage ( (both not shown). Therefore, by sliding the operation knob 8 integrated with the shutter 6 upward along the rib 11 of the support member 10, the shutter 6 slides upward (indicated by the two-dot chain line), and the inlet base 7 The opening of the inlet 16 can be adjusted.

The support member 10 is integrally formed with a mounting leg 17 extending toward the cap body 1 on the back surface thereof, and is inserted into a mounting hole (not shown) that is previously formed through the cap body 1 in correspondence with the mounting leg 17. It is fixed onto the cap body 1 by inserting it, protruding its tip into the inside of the cap body 1, and heat caulking the protruding portion.

Therefore, when attaching the visor 2 to the cap body 1,
First, attach the tip of the visor side engaging protrusion 14 to the supporting member 1.
After fitting into the engagement recess 13 of No. 0, it is fixed with screws 3 on both left and right sides of the cap body 1. That is, the visor 2 is supported with respect to the cap body 1 by the screws 3 on both left and right sides, the cap body side engagement protrusion 12, and the visor side engagement protrusion 14, and the tip of the visor side engagement protrusion 14 is fitted into the engagement recess 13 and securely locked. Therefore, even if the visor 2 is strongly hit by driving wind or gusts of wind, rattling etc. can be effectively prevented. Moreover, in this embodiment, the engaging protrusions are arranged as follows: the cap side engaging protrusion 12 and the visor side engaging protrusion 1.
Since it is composed of two parts, visor 2 and 4,
Even if the distance between the cap body 1 and the cap body 1 is increased, sufficient support strength can be ensured. Moreover, the rear open portion of the ventilation passage 4 can be maintained in an open state for a long period of time. Furthermore, since the support member 10 is effectively utilized to provide the operation knob 8 guided by the support member 10, the operation knob 8 can be disposed near the front edge of the cap body 1, and operability is improved.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications and applications are possible. For example, the above-mentioned engaging members are provided with a pair of cap-side engaging protrusions 12 of the support member 10 and a pair of visor-side engaging protrusions 14 of the visor 2, but each pair may be used as a single protruding member while traveling. This can prevent rattling caused by wind to some extent. Alternatively, a recess may be formed at the tip of the visor-side engaging protrusion 14 of the visor 2, and the tip of the cap-side engaging protrusion 12 of the support member 10 may be formed into a claw shape. Furthermore, the visor side engaging protrusion 14 of the visor 2 is extended, and the corresponding support member 1
A similar effect can be obtained by simply forming a recess without forming a protrusion in the recess, and fitting and locking the visor-side engaging protrusion 14 into the recess. Of course, it is also possible to reverse this relationship.

[Effects of the invention] The helmet with a visor of the present invention has an engaging protrusion between the cap body and the visor, whereby the cap body is provided with an engaging protrusion at least three places on the front and both sides at intervals. The visor is supported, and an open front and rear ventilation passage is formed between the cap body and the visor. Therefore, even if driving wind or gusts of wind hit the front part of the helmet, these winds can be blown through the ventilation passage in the front and rear directions, making it difficult for the visor to be blown away. Furthermore, since the visor is supported not only on both sides of the cap body but also on the front part of the cap body by the engaging projections, rattling can be suppressed and the generation of noise associated with this can be prevented.
In addition, by supporting the visor with the engaging protrusion,
The rear open portion of the ventilation path can remain open for a long period of time.

Furthermore, the engaging protrusion can be provided by effectively utilizing the support member that guides the shutter. Moreover, since it is hidden behind the visor and cannot be seen from the outside of the visor, it can be made without spoiling the appearance.

What's more, you can open and close the shutter by inserting your finger through the front opening of the ventilation duct.
