Regarding ventilation equipment.

(2) Conventional technology Conventionally, ventilation systems for this type of helmet include:
There is one in which an air guide hole is formed in the front wall of the cap body for introducing the driving wind into the cap body, and an exhaust hole is formed in the rear wall of the cap body for discharging the introduced traveling wind.

(3) Problems that the invention aims to solve However, with this helmet, an exhaust hole for discharging the running wind must be specially drilled in the rear wall of the helmet, which requires a lot of effort in manufacturing the helmet.
Furthermore, since the hole is formed in the rear wall of the helmet, the aesthetic appearance of the helmet is also impaired.

An object of the present invention is to provide a ventilation system for a helmet that eliminates the above-mentioned problems.

B. Structure of the device (1) Means for solving the problems In order to achieve the above-mentioned purpose, the present invention has the following features: It consists of a lower shell that is joined to the lower part of the shell and covers the lower side of the head, and the upper edge of the rear wall of the lower shell is recessed inward from the inner surface of the upper shell to form a groove between the upper and lower shells. It is characterized by the formation of an exhaust hole.

(2) Function To form an exhaust hole for discharging running wind to the outside of the cap body by simply recessing the upper edge of the rear wall of the lower shell into a groove shape inward from the inner surface of the upper shell. This makes manufacturing the helmet easier. In addition, the exhaust hole is formed by recessing the upper edge of the rear wall of the lower shell without drilling a hole in the shell, so the exhaust hole is not directly visible from the outside and can be easily seen from the helmet. The beauty is not compromised.

(3) Embodiment Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. In FIGS. 1 to 5, 1 is a helmet for a rider of a motorcycle, and a shell 3 forming the outer shell of a cap body 2 is a helmet. It is composed of an upper shell 3a made of hard highly reinforced synthetic resin that covers the upper side of the wearer's head, and a lower shell 3b made of hard synthetic resin that extends downward from the upper shell 3a and covers the lower side of the wearer's head.

As shown in FIG. 5, a stepped surface 4 is formed around the entire circumference of the upper edge of the outer wall surface of the lower shell 3b, and tongue pieces 5 are extended at appropriate locations on the upper edge of the stepped surface 4. be done. Further, in the rear outer wall surface of the lower shell 3b, a groove 6b is recessed with its upper edge toward the inside of the cap body 2.
A plurality of grooves (two in this embodiment) are formed, and a U-shaped notch 6a is formed at the upper end of the groove 6b.

In order to join the upper and lower shells 3a and 3b, the upper shell 3 is attached to the step surface 4 of the lower shell 3b.
overlap the upper shell 3a and the lower shell 3
The tongue piece 5 of b is connected via a rivet 7. In this case, an adhesive may be applied to the stepped surface 4 and the abutting surface of the upper shell 3a in order to strengthen the bond between the two shells 3a and 3b. Thus, an exhaust hole 6 is formed at the joint between the upper and lower shells 3a and 3b, which has a gap with the inner surface of the upper shell 3a and communicates with the inside and outside of the cap body. A rubber seal string 8 is attached to the outer periphery of the joint between these two shells 3a, 3b and the head of the rivet 7 in order to prevent dust from entering the cap body from this joint and to make the appearance beautiful. is glued.

An L-shaped stopper 9 with a locking groove 9a formed on the opposite surface of the side wall of the cap body is attached to the joint portion of the upper and lower shells 3a, 3b on both sides of the front side of the cap body, and both sides are connected through the stopper 9. The shells 3a, 3b are riveted together. A hook protrusion 7a is formed on the outwardly projecting portion of this rivet.

A buffer liner 10 made of foamed polystyrene is inserted into the inner surface of the shell 3, and the liner 10 further includes:
Several elongated upper pads 11 made of urethane foam with excellent cushioning properties are adhered to the ceiling surface, and a headband-shaped sweat stopper 12 having breathability and cushioning properties is adhered to the lower inner peripheral surface. The front wall of the buffer liner 10 has a plurality of relatively small diameter air guide holes 13 (two in this embodiment) that communicate with the inside of the cap body 2.
This air guide hole 13 has an opening 13 in the front wall of the cap body.
I'm doing a. Further, an air supply hole 14 is bored in the buffer liner 10 facing the notch 6a of the groove 6b.
It communicates with the exhaust hole 6.

A visor 15 and a shield plate 16 are attached to the front surface of the cap body 2 above the opening 13a of the air guide hole 13.

The visor 15 has an arcuate front end and a gently curved plane, and is attached to the cap body 2 with a slight downward inclination toward the front, as shown in FIG. Both ends of the visor 15 are bent downward, and an abutment piece 17 is provided at the end closer to the cap body, and a screw hole (not shown) is provided above the abutment piece 17. A locking protrusion 18 is provided protruding from the tip of 17.

Windows 20 are formed on the surface of the visor 15 facing the cap opening 13a, and around these windows 20, a guiding surface 21 for guiding wind toward the opening 13a is formed. An opening/closing lid 22 for opening or closing the window 20 is attached to the window 20, and the opening/closing lid 22 is attached to the back side of the visor 15.
An opening/closing mechanism 23 is mounted which can hold the window 20 in the open or closed position (see FIG. 4).

The shield plate 16 is formed by bending a transparent plastic plate along the front arcuate surface of the visor 15, and has screw holes (not shown) above both ends, and holes for the stopper 9 below both ends. A hook recess 7b is formed which engages with the projection 7a.

In the figure, reference numeral 24 denotes a positioning member for holding and fixing the shield plate 16 in front of or above the visor 15, and the positioning member 24 is also provided with screw holes (not shown).

Therefore, in order to attach the visor 15 and the shield plate 16 to the cap body 2, first, the locking protrusions 18 extending from the contact pieces 17 at both ends of the visor 15 are attached to the stoppers 9 fixed to the front left and right sides of the cap body 2. After fitting into the locking groove 9a and subsequently inserting the screw 25 into each screw hole of the visor 13, shield plate 14, and positioning member 24, insert the screw 25 into the screw mounting hole 26 screwed in the side wall of the cap body in advance. It is done by screwing. By the way, the visor 15 is connected to the upper end of the stopper 9 and the abutment piece 1.
Rotation around the screw 25 is prevented by contact with the lower end of the screw 7, and positioning is achieved by fitting the locking protrusion 18 into the locking groove 9a. Therefore, the visor 15 can be reliably fixed to the cap body 2 by simply fastening the screws 25 at both ends.
Its installation and removal becomes extremely easy.

In the figure, 42 is a side pad that accommodates the ear area of the wearer of the cap body 2, 43 is a cheek rest, and 44 is a cap body 2.
This is a chin belt for securing the head to the head.

Next, the operation of this embodiment will be explained.

A wearer puts on the cap body 2, rotates the shield plate 16 downward, and holds it on the front surface of the cap body. At this time, the hook protrusion 7a on the cap body 2 side and the shield plate 16
The hook recess 7b on the side is engaged with the hook recess 7b. Next, the opening/closing mechanism 23 of the visor 15 is operated to open the left and right windows 20. Then, as shown by the arrow in FIG. Introduced into the body 2. Thereafter, the air flows inside the cap body 2, passes through the air supply hole 14 at the rear of the cap body, and is discharged to the outside of the cap body through the exhaust hole 6 from the notch 6a formed in the lower shell.

C. Effects of the invention As described above, according to the invention, the shell forming the outer shell of the cap body is joined to the upper shell that covers the upper side of the wearer's head, and the upper shell is joined to the lower part of the wearer's head. The upper edge of the rear wall of the lower shell is grooved inward from the inner surface of the upper shell to form the exhaust hole between the upper and lower shells. The exhaust hole can be formed by a simple process of recessing the upper edge of the wall inward from the inner surface of the upper shell in the form of a groove, which facilitates manufacturing of the helmet and contributes to cost reduction. Further, since the exhaust hole is constructed by recessing the upper edge of the rear wall of the lower shell, the exhaust hole is not directly visible from the outside of the helmet, so that the aesthetic appearance of the helmet is not impaired.
