Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helmet, and more particularly to improvement of a jet type helmet which does not cover a chin.

[0002]

2. Description of the Related Art Conventionally, there are two types of helmets, which are worn for safety purposes when riding a motorcycle or automobile, for a full face type helmet that covers the chin and a jet type helmet that does not cover the chin. The former full face type helmet is superior to the jet type helmet in safety because the part covering the chin is formed in the same body as the cap body. However, because of the structure that covers the chin, it feels suffocating, glasses users need to put on their glasses again when wearing or removing the helmet, and because part of the face is hidden, it is used for criminal purposes. However, some stores, etc. require that you take off your helmet when entering the store.
This is very troublesome for helmet wearers. In this respect, the latter jet-type helmet is convenient because it does not cause the above-mentioned problems, but is concerned about the safety of protecting the face.

In addition to the above-mentioned two types, a chin guard arm (mouse card) that crosses the front open part of the hat body of a jet type helmet and extends across the left and right sides is attached to allow the full face type and the jet type to be used. It can be seen that a helmet is used, for example, JP-A-63-22780.
No. 4, etc. are mentioned.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention The above-described method of overall connection between a chin guard arm and a cap body, which are separately molded, is a holder having a slight step difference with the cap body, a mating engagement with an interior material, or a holder having less strength. In many cases, it is engaged by a simple method such as coupling with a cover, etc., and in addition to a screw that rotatably supports the chin guard arm, most of the hook buttons and relatively small members for locking are used for engagement. Is the reality. Therefore, regarding protection of the chin part, no chin guard arm having a structure different from that of the cap body is attached, so that there is no one that exhibits the same performance as a full-face helmet.

The present invention has been made in view of the problems of the above-mentioned conventional techniques, and an object thereof is to provide a jet provided with a chin guard arm having a front surface protection function equivalent to that of a full-face type helmet. To provide a type helmet.

[0006]

In order to achieve the above-mentioned object, the technical means taken by the present invention is to rotate a front opening of a cap body having an open jaw with a left and right side portions of the cap body as fulcrums. A helmet in which a chin guard arm that is covered by a moving shield and that covers the wearer's chin across both left and right sides of the hat body is pivotally and lockably attached to the shaft support portion of the shield. The contact surfaces of the lower front edges of both sides and the chin guard arm are engaged with each other in a substantially S shape or a substantially V shape, and the contact surface on the side of the cap body is inside the chin guard arm when an external force is applied to the chin guard arm from the front. It is an inclined surface that guides toward one side, and further, one of the contact surfaces with the chin guard arm on the left and right sides of the cap body is crossed over and engaged when turning in the direction to close the chin guard arm,
It is equipped with a locking mechanism consisting of an uneven engaging means that prevents the movement when rotating in the opening direction and unlocks the engagement state by expanding the chin guard outward so that it can rotate in the opening direction. Characterize.

The above-mentioned contact surface with the chin guard arm on the side of the cap body is formed directly at a predetermined position of the cap body itself, or
Alternatively, the chin guard holder, which is a resin molded product separate from the cap body, may be formed and the molded product may be fixed to a predetermined position of the cap body. The lock mechanism provided on the contact surface between the cap body and the chin guard arm is composed of a saw-tooth-shaped projection formed on the chin guard holder side and a saw-tooth-shaped recess formed on the chin guard arm side. It may be provided on either one of the left and right side surfaces of the body or on the left and right side surfaces. When the lock mechanism is provided on both sides, a temporary fixing part for temporarily holding the projection on the edge of the chin guard arm side recess of either one of the lock mechanisms at a position where the projection is overcome (state where the recess is disengaged from the projection) is provided. Form. Furthermore, the shield covering the front opening may be configured to rotate up and down integrally with the chin guard arm, or the chin guard arm and the shield may be separated and only the shield may be independently moved up and down. It's good.

[0008]

According to the above-mentioned means, the chin guard arm rotatably mounted on the left and right sides of the cap body in the up and down direction has contact surfaces with the cap body at the left and right side portions of the chin guard arm which are "S". Since they engage with each other in a V shape or a V shape, even if a shock is applied to the chin guard arm from the front, external force can be transmitted to the coupling (shaft support) with the cap body and the opening / closing mechanism part of the chin guard arm. It prevents the chin guard arm from falling off and protects the wearer's face.

Further, when an impact is applied to the chin guard arm from the front side, the contact surface on the cap side of the meshing engagement portion of the arm is inclined inward, so that the left and right sides of the chin guard arm act inward (close direction). This prevents the chin guard arm from coming off the cap. Moreover, one or both sides of the left and right meshing engagement parts of the chin guard arm and the cap body are engaged by crossing over when the chin guard arm is rotated in the closing direction, and blocked when rotating in the opening direction. However, since the engagement state is released by expanding the chin guard to the outside and the lock mechanism including the uneven engagement means capable of rotating in the opening direction is provided,
Even if the chin guard arm is simply rotated upward, safety is ensured without being opened, and there is little risk that the chin guard arm will be opened forward no matter which side the impact acts on the chin guard arm.

When the chin guard arm attached to the cap body is opened upward, the lock mechanism provided on one side or both sides of the cap body must be released, but when the lock mechanism is provided only on one side. Can be opened by pushing up in the direction in which the chin guard arm can rotate (upward) while spreading the lower side of the arm equipped with the lock mechanism in the direction away from the hat body (outward). Also, if the lock mechanism is provided on both the left and right sides of the cap body, there is no problem in operating both hands at the same time to remove and open the lock mechanism, but often only one hand can be used while riding a motorcycle, The procedure for opening with one-handed operation is to push the lower part of the chin guard arm on the lock mechanism side that has the temporary fixing part in the direction (outward direction) away from the cap body and rotate the chin guard arm (upward direction). It is possible to open the chin guard arm in two steps by pushing it up to) and placing a temporary fixing part formed on the edge of the recess of the chin guard arm on the protrusion, and then removing the lock mechanism on the opposite side in the same procedure. In order to fully close the open chin guard arm, push down the chin guard arm with your hand, ride over the projection provided on the contact surface on the side of the cap body as it is, and make contact contact between the contact surface of the chin guard arm and the cap body. Complete by checking that it stops.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the helmet according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a helmet equipped with a chin guard arm, in which 1 is a jet type having a known shape today. The front opening of the cap body 1 is covered with a shield 2 made of a transparent plate or a semitransparent plate and a chin guard arm 3 arranged below the shield 2. Both sides are rotatably attached to both sides of the cap body 1 by a rotation support mechanism 4. And, as for the shield 2 and the chin guard arm 3, only the shield 2 may be independently opened and closed, or the shield 2 and the chin guard arm 3 may be opened and closed together. Further, the rotation support mechanism of the shield 2 and the chin guard arm 3 can be equipped with a moderating means by frictional engagement so that the shield 2 and the chin guard arm 3 can be opened and closed by providing moderation. .

The chin guard arm 3 is formed in such a shape as to cover the chin of the wearer over the left and right sides of the cap body, and the upper parts on the left and right sides are rotatably supported by the upper parts on both sides of the cap body 1. The rear edges 5 extending from the rear side edge around the support section to the lower portions on both sides straddling the opening of the cap body 1 are brought into contact with and engaged with the step portions 6 formed on both sides of the cap body 1, and at the lower front portion of the step portion 6. Has a contact surface 7 having a substantially S-shaped front surface continuously formed.

The contact surface 7 is formed by a chin guard holder 8 composed of a substrate 8a made of a synthetic resin material and a body 8b joined to the upper side of the substrate 8a. The substrate 8a and the body 8b are separated from each other. The main body 8b is fixed to the cap body 1 by screwing or the like from the inside. A protrusion 9a forming the lock mechanism 9 is formed on the substrate 8a so that the main body 8b
As described above, the outer peripheral surface of the chin guard arm 3 that contacts the chin guard arm 3 is substantially S-shaped, and the substantially S-shaped outer peripheral surface (the surface that engages and contacts the chin guard arm) is inclined inward. Is formed on the surface.

That is, the contact surface 7 between the cap body 1 and the chin guard arm 3 described above is inward (closed direction) on both sides of the chin guard arm 3 when a shock is applied to the chin guard arm 3 from the front.
It is inclined inward to act on.

The lock mechanism 9 comprises a sawtooth-shaped projection 9a formed on the substrate 8a side and a sawtooth-shaped recess 9b formed on the chin guard arm 3 side. The lock mechanism 9 is provided on the left and right side surfaces of the cap body 1. Is provided on at least one of the two sides so that the opening operation can be performed with one hand. Further, even when the lock mechanism 9 is provided on both the left and right sides of the cap body 1, in order to enable the opening operation with one hand as in the case where the lock mechanism 9 is provided on one side, the recess 9b of at least one lock mechanism 9 is formed. A temporary fixing portion 10 for temporarily locking the chin guard arm 3 over the projection 9a is formed at the edge portion. Needless to say, the temporary fixing portion 10 may be provided on both sides of the lock mechanism.

Next, the opening / closing operation of the chin guard arm 3 in the above-mentioned helmet will be described. First, when the chin guard arm 3 in the fully closed state shown in FIG. 1 is opened, a lock mechanism provided on both left and right sides of the cap body 1. 9 must be released, but when the lock mechanism 9 is provided only on one side of the cap body 1, the lower part of the chin guard arm 3 on the side equipped with the lock mechanism 9 is separated from the cap body 1 ( It is pushed outward to disengage the protrusion 9a from the recess 9b (see FIG. 4).
(See (c)), and from that state, the chin guard arm 3 can be opened by pushing it up in the rotatable direction (upward direction) of the chin guard arm 3. (See Figure 4 (d))

Further, when the lock mechanism 9 is provided on both the left and right sides of the cap body 1, the releasing operation is performed on the lower side portion of the arm 3 on the side where the lock mechanism 9 is provided on the side where the temporary fixing portion 10 is provided. Temporary fixing part formed on the edge of the recess 9b of the chin guard arm 3 by pushing it up in the direction in which the chin guard arm 3 can rotate (upward) while spreading it in the direction away from the cap body 1 (outward direction).
10 is placed on the protrusion 9a to temporarily hold that state, and then the lock mechanism 9 on the opposite side is similarly removed to release the left and right lock mechanisms 9 of the chin guard arm 3. Then, both sides of the chin guard arm 3 are kept in the same state, and the chin guard arm can be opened by pushing the arm 3 upward from that state, and the angle of the opening can be adjusted by a moderation means attached to the rotation support mechanism. Set to the opening angle of. In the case where the lock mechanisms 9 on both the left and right sides are provided with the temporary fixing portions 10, the left and right functions are the same, and therefore the lock can be released with one hand even if starting from either the right or the left. Further, in order to fully close the open chin guard arm 3, the chin guard arm 3 is pushed down by hand, and the projection 9b of the lock mechanism 9 provided on the contact surface 7 on the side of the cap body 1 as it is.
It is completed by climbing over and confirming that the chin guard arm 3 and the contact surface 7 of the cap body 1 come into abutting engagement and stop.

[0018]

The helmet of the present invention has the structure of claim 1 when a shock is applied to the chin guard arm from the front.
The chin guard arm does not open easily, especially with the hat body.
It is possible to protect the wearer's face with performance equivalent to that of a full-face type helmet by preventing the chin guard arm from falling off without transmitting force to the rotation support mechanism part. Further, since the lock mechanism is provided on the contact surface between the cap body and the chin guard arm, it is possible to prevent the chin guard arm from being opened accidentally due to the influence of the wind or shock, and to reliably protect the wearer's face. it can.

Further, in the case of the structure described in claim 2, the contact surface which abuts against the chin guard arm can be molded with high productivity, and even if the contact surface on the side of the cap body is worn, the contact surface is contacted. It is very convenient that the initial engagement state can be maintained by exchanging only the chin guard holder (molded product) having a separate structure from the cap body forming the surface.

Further, in the case of the structure described in claim 3,
The left and right lock mechanisms are released to bring the left and right states into the same state, and then the chin guard arm is pushed up, so that the chin guard arm rotates very smoothly. Therefore, the operation to open the chin guard arm in the fully closed state is
The lock mechanism can be released with one hand regardless of whether it is started from the left side, and opening and closing operations can be performed easily.
