Description

[Detailed explanation of the invention] A. Purpose of the invention (1) Industrial application field The present invention is a cap consisting of a shell and a shock absorbing liner lined with the shell, and has a cap just below the front window hole. The present invention relates to an exhalation guide plate attachment structure for a helmet, in which an exhalation guide plate is attached to the wearer's body to prevent the wearer's exhaled air from flowing toward the window hole.

(2) Prior art In the above-mentioned helmet, an exhalation guide plate is attached to the chin part of the cap body and extends inside the cap body.
A device in which the window hole is closed with a shield plate to prevent the inner surface of the shield plate from fogging due to the exhalation of the wearer is already known, for example, as disclosed in Publication of Utility Model Publication No. 63-9538. In the known case, a hook-and-loop fastener is used in the structure for attaching the exhalation guide plate to the cap body.

(3) Problems to be solved by the invention When using hook-and-loop fasteners in the structure for attaching the exhalation guide plate to the cap body, the male-type hook-and-loop fastener is sewn to the exhalation guide plate, and the female-type hook-and-loop fastener is attached to the shock absorber on the cap body. It is sewn to the covering fabric of the absorbent liner, or the covering fabric is also used as a female surface fastener.

However, in the case where the female surface fastener is attached to the shock absorbing liner, the female surface fastener is exposed when the exhalation guide plate is removed, and the covering fabric of the shock absorbing liner is also used as the female surface fastener. In this case, the covering fabric becomes fluffy as it is repeatedly joined and separated from the male surface fastener, and either of these causes some deterioration in the appearance of the cap body with the exhalation guide plate removed. Furthermore, when the above-mentioned surface fastener is used to attach the exhalation guide plate, it is not easy to accurately define the attachment position of the exhalation guide plate to the jaw cover.

The present invention was proposed in view of the above circumstances, and allows the exhalation guide plate to be easily and securely attached to the cap body in a fixed position without using a hook-and-loop fastener. To provide a structure for mounting an exhalation guide plate on a helmet without damaging the appearance of the body.

B. Structure of the device (1) Means for solving the problem In order to achieve the above object, the present invention provides a retaining plate that has elasticity and covers the upper surface of the shock absorbing liner in the jaw cover, and provides an exhalation guide. A first mounting member connected to the front edge of the plate and extending forward is inserted between the holding plate and the shock absorbing liner, and a locking hole is formed in one of the opposing surfaces of the holding plate and the first mounting member. and the other is provided with a protrusion that engages with the locking hole, and the first
Insert the downwardly extending legs of the second mounting members connected to both sides of the exhalation guide plate with the mounting members in between, and insert the legs between the shell of the jaw cover and the shock absorbing liner. It is characterized in that a locking claw formed at the lower end digs into the wall surface of the shock absorbing liner.

(2) Function When installing the exhalation guide plate, place the first mounting member in the gap between the elastic holding plate and the shock-absorbing liner, and place the legs of the second mounting member in the gap between the shell of the cover jaw and the shock-absorbing liner. Insert each into the gap between them. By inserting these, the locking holes and the protrusions are engaged with each other, thereby accurately defining the mounting position of the exhalation guide plate, and the first
While the mounting member can be fixed to the holding plate,
The locking claws bite into the wall surface of the shock absorbing liner and the anchor effect allows the second mounting member to be fixed to the shock absorbing liner, and as a result, the exhalation guide plate can be easily and securely placed in the fixed position of the jaw cover. It can be installed on.

In particular, if the presser plate is slightly elastically deformed when inserting the first mounting member into the corresponding gap, the engagement between the locking hole and the protrusion can be easily performed. Furthermore, when the exhalation guide plate is removed, there is nothing on the cap body that will damage its appearance, and even if the wall surface of the shock absorbing liner is damaged to some extent by repeated attachment and detachment of the second mounting member, the damaged portion will not be damaged. is covered with shell.

First, in Figures 1 and 2, helmet 1
The cap body 2 is formed in a full-face shape with a chin cover 2a that covers the wearer's chin directly below the window hole 3 on the front surface. A transparent shield plate 4 is pivotably supported on the cap body 2 so as to be movable up and down in order to open and close the window hole 3. Further, an exhalation guide plate 16 that covers the wearer M's nose from above is attached to the jaw cover portion a.

In FIGS. 3 to 5, the cap body 2 includes a shell 6 made of fiber-reinforced synthetic resin and a shock absorbing liner 7 made of expanded polystyrene lined with the shell 6.
A rubber seal member 9 is attached to the shell 6 along the periphery of the window hole 3. This seal member 9 is adapted to come into close contact with the inner surface of the shield plate 4 when it is closed.

In the covered jaw part 2a, a synthetic resin air guide member 8 is fitted between the shell 6 and the shock absorbing liner 7, and the protrusion 8a on the front surface of the member 8 is engaged with the locking hole 13 of the shield member 9. will be combined. This air guide member 8 defines a plurality of ventilation passages 10 whose upper ends are opened toward the window hole 3 between the inner surface of the shell 6 and the lower ends of the ventilation passages 10 are bored into the shell 6. It communicates with the air intake hole 11. This air intake hole 11 is opened and closed at any time by a shutter 12 attached to the front surface of the shell 6.

A pressing plate 14 is integrally provided on the upper edge of the air guide member 8, and has elasticity which cooperates with the upper surface of the impact absorbing liner 7 of the covering jaw portion 2a and covers the upper surface of the liner 7.
The pressing plate 14 has a locking hole 15 formed in the center.

On the other hand, the exhalation guide plate 16 is shown in FIGS.
As shown in the figure, there is a flexible guide plate body 17 made of synthetic resin soft foam cut to cover the wearer's nose from above, and a synthetic resin sewn to the front edge of the guide plate body 17. A first mounting member 18 made of synthetic resin, and a second mounting member 19 made of synthetic resin sewn to both sides of the guide plate body 17 with the first mounting member 18 in between.
It consists of 19. and the first mounting member 18
is equipped with three tongue pieces 18a, 18b, and 18c extending horizontally forward from the guide plate main body 17, and a projection 20 that can be engaged with the locking hole 15 is provided on the upper surface of the central tongue piece 18b. are integrally formed.
Further, each second mounting member 19 includes a leg portion 21 extending substantially perpendicularly downward from the guide plate main body 17, and a leg portion 21 extending downward from the guide plate main body 17.
The stopper part 22 is horizontally bent inward from the upper end of the cap body 2, and the stopper part 22 is sewn to the guide plate main body 17. Further, a locking pawl 23 protruding inwardly from the cap body 2 is provided at the lower end of the leg portion 21.

The removal of the breath guide plate 16 is performed in the reverse order of the above installation. After removal, nothing remains on the cap body 2 that would impair its appearance, and the engagement marks of the locking claws 23 on the shock absorbing liner 7 are covered by the shell 6, so the appearance of the cap body 2 is not marred by this.

Therefore, the rider M of the motorcycle uses the exhalation guide plate 16.
When the occupant M wears the helmet 1 with the attached helmet, the nose of the occupant M is covered from above by the exhalation guide plate 16, so that the occupant breathes through the lower opening of the cap body 2 below the exhalation guide plate 16. The exhaled air is prevented from moving toward the window hole 3 by the exhaled air guide plate 16. Therefore, even if the window hole 3 is closed by the shield plate 4 at that time, the inner surface of the shield plate 4 will not be clouded by exhaled air.

On the other hand, if the shutter 12 is opened while the motorcycle is running, the running wind enters the air intake hole 11, ascends the ventilation passage 10, and is blown against the inner surface of the shield plate 4, so that the hot air from the rider It is also possible to prevent the inner surface of the shield plate 4 from fogging up.

Incidentally, by integrally connecting the presser plate 14 to the air guiding member 8 as in this embodiment, there is no need for a special fixing means for the presser plate 14, which not only simplifies the structure. First, this is an extremely effective structure for avoiding interference with the ventilation passage 10 by the presser plate 14 and the first mounting member 18.

In the figure, reference numeral 24 indicates a cheek rest pad, and 25 indicates a chin cover.

C. Effects of the invention As described above, according to the invention, a retaining plate is provided in the jaw cover portion and has elasticity and covers the upper surface of the shock absorbing liner, and is connected to the front edge of the exhalation guide plate and extends forward. A first mounting member is inserted between the holding plate and the shock absorbing liner, and a locking hole is formed in one of the facing surfaces of the holding plate and the first mounting member, and a locking hole is formed in the other side of the holding plate and the shock absorbing liner. mating protrusions are respectively provided, and downwardly extending legs of second mounting members connected to both sides of the exhalation guide plate are connected to the shell of the jaw cover and the shock absorbing liner with the first mounting member therebetween. At the same time, the locking claws formed at the lower ends of the legs were inserted into the wall surface of the shock absorbing liner. By inserting the legs of the second mounting member into the gap between the liners and the gap between the shell of the jaw cover and the shock absorbing liner, the exhalation guide plate is secured by the engagement of the protrusions with the locking holes. While the first mounting member can be fixed to the holding plate while accurately defining the mounting position, the second mounting member can be fixed to the shock absorbing liner due to the anchor effect caused by the locking claw biting into the wall surface of the shock absorbing liner. Therefore, the exhalation guide plate can always be easily and securely attached to the fixed position of the jaw cover, so it can accurately cover the area around the user's nose and minimize the leakage of exhaled air. In addition, there is no need to use a special hook-and-loop fastener to attach the exhalation guide plate.

In particular, when inserting the first mounting member into the corresponding gap, by slightly elastically deforming the holding plate, the locking hole and the protrusion can be engaged with each other without any trouble. Furthermore, when the exhalation guide plate is removed, there is nothing on the cap body that will spoil its appearance.
In particular, even if the wall surface of the shock absorbing liner is damaged to some extent by repeated attachment and detachment of the second attachment member, the damaged portion is covered by the shell, so that the appearance will not be impaired.
