Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chin belt device used when a user puts on a helmet.

A conventional chin belt device connects a short left belt fixed to the left side wall of the cap body of a helmet and a long right belt fixed to the right side wall of the cap body through a buckle or connecting ring. but,
Inconveniently, the user must use both hands to operate the buckle or connecting ring when attaching or detaching the chin belt.

Therefore, the object of the present invention is to provide a new chin belt device that allows the chin belt to be easily attached and detached with one hand. A guide rail is provided, and the other end of the chin belt, which has one end fixed to one side wall of the cap body, is movably engaged with the guide rail.

Hereinafter, an embodiment in which the present invention is applied to a full-face helmet for riding will be explained with reference to the drawings. In Fig. 1, 1 is a cap body, which is equipped with a transparent shield plate 3 that opens and closes a window hole 2 on the front side. A cushioning material 4 is polymerized and bonded to the inner surface of the cap body 1.

One end of a chin belt 5 is fixed to the left side wall of the cap body 1 by a rivet 6 on the inside thereof, and the chin belt 5 is provided with a known length adjustment device 7 in the middle thereof (see FIG. 4).

A guide rail 8 is provided substantially along the lower edge of the front half of the cap body 1. This guide rail 8 has a T-shaped cross section and has a rail groove 9 with the open surface facing the front of the cap body 1.
and a rail main body 10 having a dead end groove 9' continuous to one end of the rail groove 9.
A first terminal 11 is connected to one end of the rail groove 9, and a second terminal 12 is connected to the other end of the rail main body 10 so as to close the other end of the rail groove 9.
A mounting belt 13 extending upward is connected to the first terminal 11, and an enlarged end portion 1 is provided on the upper surface of the rail main body 10 at an intermediate portion thereof and adjacent to the second terminal 12.
A branch piece 14 having 4a is integrally protruded,
The mounting belt 13 is fixed to the right side wall of the cap body 1 by a rivet 6' at a position opposite to the rivet 6,
Further, the enlarged end portion 14a of the branch piece 14 is held between the cap body 1 and the cushioning material 4 (see FIG. 6).

A slider 15 that can slide in the rail groove 9 and dead end groove 9' is attached to the guide rail 8, and a terminal plate 5 provided at the other end of the chin belt 5 is attached to the slider 15.
a is connected.

As shown in FIG. 5, the slider 15 is provided with a lock pin 16 passing through it in the axial direction.
A spring 17 is provided in the slider 15 to urge the inner end of the lock pin 16 to protrude toward the inner surface of the grooves 9, 9', and the outer end of the lock pin 16 protrudes to the outside of the slider 15. A knob 16a is integrally formed therein.

On the other hand, a lock pin 16 is provided on the inner surface of the dead-end groove 9'.
A lock hole 18 is provided in which the tip of the lock hole 18 can be engaged.

Next, the operation of this embodiment will be explained. First, as shown in FIG. , the user can wear the cap body 1 without being obstructed by the chin belt 5. By putting on the cap body 1 and moving the slider 15 to the dead end groove 9' of the first terminal 11, the chin belt 5 is naturally placed under the user's chin.

When the slider 15 is moved to the end wall of the blind groove 9' of the first terminal 11, the lock pin 16 is moved by the spring 17.
Since the slider 15 is engaged with the lock hole 18 by the elastic force of the slider 15, the slider 15 is locked to the first terminal 11. Therefore, blind movement of the slider 15 can be reliably prevented during use. In this case, if the length of the chin belt 5 is inappropriate, the length adjustment device 7 is operated in the usual manner to adjust it appropriately.

To remove the chin belt 5, pull the knob 16a of the lock pin 16 against the elastic force of the spring 17 to remove the lock pin 16 from the lock hole 18, and then move the slider 15 to the position of the second terminal 12. move it,
In this way, the chin belt 5 is removed from under the user's chin. In this case, once the slider 15 starts to move, the lock pin 16 can slide on the inner surfaces of the grooves 9, 9' even if the knob 16a is released.
movement is not hindered.

The present invention can also be applied to a jet-type helmet, in which case both ends of the guide rail 8 must be secured to the cap body.

As described above, according to the present invention, a guide rail is provided along the lower edge of approximately the front half of the cap body of a helmet, and the other end of the chin belt, one end of which is fixed to one side wall of the cap body, can be freely moved to the guide rail. , the chin belt can be attached and detached by simply moving the other end of the chin belt along the guide rail.
Therefore, this operation can be easily performed by the user with one hand, which is extremely convenient.
