FIG. 2 is an enlarged side sectional view around the headphones 4.

The headphone 4 is a pad 7 for absorbing shock,
It is supported in the hollow cylindrical portion 9 between 8 so as to be able to approach and separate in the left-right direction. A spring 10 as a pressing mechanism is inserted between the inner wall of the helmet 1 and the headphones 4, one end of the spring 10 is locked to the helmet 1 and the other end is locked to the rear end of the headphones 4. The spring 10 urges the headphones 4 in a direction (rightward direction) in which the ears of the helmet wearer are pressed. The spring 10 is not limited to a coil spring, but a spring member such as a leaf spring, a flat spring, and a spring can be used.

At the rear end of the headphones 4 are three wires 1
A knot is provided at the center of the headphones 4 in the left-right direction so that the headphones 1, 12 and 13 are locked and the headphones 4 are moved horizontally by applying a uniform force. One end of the wire 14 is locked to this knot, and the other end is locked near the left end of the visor 6. The covering pipe 15 horizontally penetrates the helmet 1 and is fixed to the inner wall thereof, and regulates the pulling direction of the wire 14.

Although the configuration around the left headphone 4 has been described above, the configuration around the right headphone 3 is similar. The wire 16 locked to the headphone 3 is guided to the periphery of the headphone 4 and connected to the wire 14. The wire 16 can be locked near the right end of the windshield visor 6.

In this embodiment, since the windshield visor 6 is closed during traveling, the windshield visor 6 and the headphones 3 and 4 are connected to the wire 1.
Although the headphones 3 and 4 are moved away from both ears when the windshield visor 6 is closed by linking them with 4, 16, instead of this, as shown in FIG. 3, the lower part of the helmet 1 (the upper part or the side part may be used. ) Is provided with a manual lever 20, and when the manual lever 20 and the headphones 3 and 4 are linked by the wires 14 and 16, the manual lever 20 is moved.

Locked in.

Further, as shown in FIG. 4, the buckle type chin strap 30 attached to the helmet and the headphones 3 and 4 are linked by the wires 14 and 16. When the chin strap 30 is tightened, the headphones 3 and 4 are worn by the person wearing the headphones. It can also be moved away from both ears. Note that the chin strap 30 is not limited to the buckle type, but may be a type in which it is hung on the chin and then tightened. Alternatively, the helmet 1 may be provided with a device for manually winding the wires 14 and 16.

Further, as shown in FIG. 5, in place of the spring 10 and the wires 14 and 16, a screw 40 fixed to the headphone 4 and an adjusting knob 41 which is screwed to the screw 40 and moves the headphone 4 left and right are used. It is also possible to press the headphones 4 against both ears of the helmet wearer, or to support the headphones 4 with a certain distance D from both ears. As shown in FIG. 6, a gear 51 to which a lever 50 is fixed, a gear 52 to which a gear screw 51 is screwed to the gear 51 and a feed screw 53 is screwed to a moving base 5 that is fixed to a headphone 4.
The headphone 4 can be moved and adjusted to the left or right by using 4 or, or a worm gear or a mechanism of a pinion and a rack may be used.

Further, as shown in FIG. 7, the helmet 1 may be provided with a plurality of vent holes 60 and a shutter 61 for opening and closing the vent holes 60 so that the shutter can be opened while the vehicle is traveling. This allows you to listen to the environmental sound positively. The attachment position of the vent hole 60 and the shutter 61 thereof is not limited to the upper part of the helmet 1 and may be the lower part or the side part. If the ventilation holes 60 are provided in the vicinity of both ears, it is possible to know the direction in which the environmental sound is generated, which is further safe.

The vent hole 60 and the shutter 61 can be added to the embodiment shown in FIGS. 1 to 6, and the wire 1
4, 16 are linked to one end of another wire, the other end is locked to the shutter 61, and a spring for urging the shutter 61 in a closing direction is provided so that opening / closing of the shutter 61 is interlocked with movement of the headphones 3, 4. You can also

The cassette tape recorder may use a microcassette tape, or may have an AM / FM stereo radio attached. As another audio device, a CD player may be used instead of the cassette tape recorder 2 or a CD player may be added.

When a helmet wearer, who will describe a series of operating states below, closes the windshield visor 6 (state shown by a solid line in FIG. 1), the locking position of the wire 14 moves with respect to the helmet 1 and the stroke extends. The headphones 4 are pulled by the wire 14 and move against the biasing force of the spring 10 (state shown by B in FIG. 2). Therefore, the headphones 4 that pressed the ears of the helmet wearer have a fixed distance D
However, in addition to the music from the headphones 4, environmental sound is transmitted to the ears at the same time. Since the wire 16 engaged with the headphones 3 is coupled to the wires 14, the headphones also move the same fixed distance D and are separated from the ears. After the headphones 3 and 4 are moved, the headphones 3 and 4 are locked to the helmet 1 by the projection pieces 18. Here, the fixed distance D is related to music from the headphones and the distance at which the wearer can hear the environmental sound at the same time as the volume of the headphones, but in the present embodiment, it is variable in the range of 0.2 to 10 mm. This is because if D does not reach 0.2 mm, it becomes difficult to hear the environmental sound when the headphone volume is high, and if D exceeds 10 mm, the headphones cannot be placed in a helmet with a small space.

When the wearer opens the windshield visor 6 (indicated by the chain double-dashed line in FIG. 1), the force of pulling the headphone 4 with the wire 14 is released, and the headphone 4 is moved to the right by the biasing force of the spring 10 ( (A state in FIG. 2). Therefore, since the headphones 4 press the wearer's ears, only the music or the like from the headphones 4 is transmitted to the ears. The headphones 3 also press the wearer's ears in the same manner.

[0025]

The following effects are brought about by carrying out the present invention. Since the driver can listen to music, conversation in a foreign language, etc. while the vehicle is traveling, it is possible to drive comfortably and effectively use time. While the vehicle is traveling, the driver can listen to music such as horns of other vehicles, warning sounds of railroad crossings and environmental sounds of police cars, sirens of ambulances, etc., which is excellent in safety. Since the helmet of the present invention is integrated with an audio device, it can be enjoyed as a personal listening room that shields environmental sounds except when the vehicle is running, and is convenient to carry. In addition, when parked, it can be used away from motorcycles, etc., which also has the effect of preventing theft.
