BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a riding helmet used by an occupant of a motorcycle or a competition vehicle.

[0002]

2. Description of the Related Art In recent years, a cap body of a riding helmet that has been widely used has a full-face type having a chin cover portion for covering a user's chin portion, and a chin cover for exposing the entire face of the user. There are two types of jet type that do not have a section.

[0003]

[Problems to be Solved by the Invention] A full-face type cap body can provide a wide protection area. When the user smokes or eats or drinks, the chin cover becomes an obstacle, so It is troublesome to remove the cap body, and the jet-type cap body reduces the protection area because there is no chin cover, but the user can smoke while wearing it. However, both have advantages and disadvantages.

The present invention has been made in view of such circumstances, and an object thereof is to provide a helmet having the advantages of the two types of cap bodies at the same time.

[0005]

In order to achieve the above object, the present invention provides a main cap body having a large window with a lower edge opened on the front surface, and a detachable structure on the left and right outer side surfaces of the main cap body. A boss that is fixedly attached to the pivot and is held between the lower position where the lower half of the large window is covered and the upper half is the small window, and the upper position where the entire large window is opened. A cap body is composed of an auxiliary cap body that can be rotated around a pivot, and the shield plate is rotatably supported by the boss inside the auxiliary cap body to open and close the small window, and the shield plate is assisted. To pinch it with the hat body,
One end of a control plate that penetrates the pivot is fixed to an auxiliary cap body, and a click stop mechanism that can hold the shield plate at an arbitrary rotating position is provided between the control plate and the shield plate.
Further, the control plate is provided with flexibility so that when the pivot is removed from the main cap body, the control plate can be bent from the other end side to be detached from the pivot.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show the entire riding helmet. In these drawings, a helmet cap body 1 is composed of a main cap body 2 and an auxiliary cap body 3, and the main cap body 2 is formed in a so-called jet type so as to cover the head except the user's face. . Therefore, the front surface thereof has the large window 4 whose lower edge is open.

The auxiliary cap body 3 includes a chin cover portion 3a which is curved so as to bulge forward, and a pair of boss covers 3a which extend upward from the left and right ends of the chin cover portion 3a and are axially supported by the left and right side surfaces of the main cap body 2, respectively. The ears 3b and 3b are provided and can be rotated between the lowered position A (FIG. 1) and the raised position B (FIG. 2). Thus, the auxiliary cap body 3 has the chin cover portion 3a at the lowered position A thereof.
The lower half of the large window 4 of the main cap body 2 is closed to cover the user's chin, and the upper half of the large window 4 is used as the small window 5, and in the raised position B, the entire large window 4 is opened. The cover portion 3a is moved above the large window 4.

A translucent shield plate 6 is pivotally supported on the auxiliary cap body 3 so as to open and close the small window 5 so as to be vertically rotatable.

An elastic seal member 14 is also adhered to the upper edge of the shell 11 of the auxiliary cap body 3 which faces the small window 5, and when the shield plate 6 is fully closed, the inner surface thereof is the seal members 13, 14 described above.
It is designed to be closely attached to.

4 to 8 and 12 show a mounting structure of the auxiliary cap body 3 and the shield plate 6. Since the mounting structure is symmetrically provided on the left and right ends of the auxiliary cap body 3 and the shield plate 6, only one of them will be described.

First, in FIGS. 4, 6 and 12, the boss 15 formed on the ear portion 3b of the auxiliary cap body 3 is rotatable about the cylindrical pivot 16 fixed to the outer surface of the main cap body 2. Is supported and retained by. The pivot 16 is fixed by screwing a screw 17 penetrating its hollow portion into an embedded nut 18 of the main cap body 2. To prevent the pivot 16 from rotating, the pivot 16 and the outer surface of the main cap body 2 are fixed. A rubber washer 19 is interposed between the and. The boss 15 projects inward of the auxiliary cap body 3, and the outer peripheral surface of the boss 15 rotatably fits the boss hole 20a of the bracket plate 20 riveted to the end of the shield plate 6. A control plate 21 is rotatably supported by a pivot shaft 16 on a central shaft hole 21a inside the bracket plate 20.

The control plate 21 is made of synthetic resin and has a mounting arm 22 projecting from the lower end of the front part. The mounting arm 22 is provided with a screw 24 on a mounting boss 23 projecting from the inner peripheral surface of the ear portion 3b of the auxiliary cap body 3. It is fixed in. Further, the control plate 21 has a stopper arm 25 protruding from the lower end of the rear portion, and a positioning hole 26 that opens to the inner side surface side in the vicinity of the stopper arm 25. The positioning hole 26 is provided on the inner side surface of the ear portion 3b. It fits into the determined positioning protrusion 27. In this way, the control plate 21 is connected to the auxiliary cap body 3 and also the bracket plate 20 is sandwiched between the auxiliary cap body 3 and the elastic force of the control plate 21. Also, the stopper arm 2
The tip portion of 5 is in contact with the inner surface of the auxiliary cap body 3.

Further, at the lower end of the control plate 21, an elastic arm 28 having one or several fixed click teeth 29 at its free end is provided.
The elastic arm 28 can bend in the radial direction of the pivot 16.

On the other hand, on the outer periphery of the bracket plate 20, a large number of movable click teeth 3 are formed in a sector shape around the pivot 16.
0, 30 ... Are formed and the fixed click teeth 29 are engaged with the elastic force of the elastic arm 28 to form a click stop mechanism 31. When the shield plate 6 is rotated, the fixed and movable click teeth 2 are accordingly moved.
The engagement positions of 9 and 30 are shifted, and the shield plate 6 can be held at an arbitrary rotation position by their engagement force.

At the fully closed position of the shield plate 6, the shield plate 6 is attached to the seal members 13 and 14 on the periphery of the small window 5 as described above.
It is regulated by the close contact of the inner surface of the, but its fully open position is such that, as shown in FIG. 9, the upper edge of the shield plate 6 contacts the step portion 38 formed on the upper edge of the ear portion 3b of the auxiliary cap body 3. It is regulated by contact.

By the way, when the shield plate 6 is detached for replacement with a new part, as shown in FIG. 7, first, the screw 17 is removed to separate the pivot 16 from the main cap body 2, and then the mounting arm. By tilting the control plate 21 toward the main cap body 2 side while bending 22, the control plate 21 is separated from the pivot 16,
Through the gap S formed between them, the boss 15 of the auxiliary cap body 3
The boss hole 20a of the bracket plate 20 is attached to and detached from. At this time, a thread-like rib 34 is formed on the outer circumference of the inner end portion of the pivot 16 in order to prevent the pivot 16 from being pulled out of the boss 15 in a dirty manner. The rib 34 is deformed when it receives a pulling-out force of a certain value or more of the pivot 16, and can pass through the hollow portion of the boss 15.

5 and 8, on the outside of the main cap body 2, an upper limit stopper member 33 constituting an upper limit regulating means 32 for regulating the raised position B of the auxiliary cap body 3 in cooperation with the stopper arm 25. Is fixed. This upper limit stopper member 33
Is a base portion 35 joined to the outer surface of the main cap body 2, an L-shaped stopper wall 36 standing upright from the front edge to the lower edge thereof, and a mountain portion 37 protruding on the rear surface of the base portion 35. It consists of Further, the front wall portion of the stopper wall 36 and the mountain portion 3
The distance from 7 is set to such a length as to receive the tip portion of the stopper arm 25.

Then, when the auxiliary cap body 3 is rotated upward from the lowered position A, the control plate 21 is also rotated with it, and when the auxiliary cap body 3 comes just before the raised position B, the control plate 21 moves. The stopper arm 25 rides over the mountain portion 37 of the regulating member 33 while slightly bending outward together with the auxiliary cap body 3 in contact with the stopper arm 25, and when the stopper arm 25 crosses the mountain portion 37, the stopper arm 25 is immediately
As shown in (3), since it is received by the front wall portion of the stopper wall 36, the raised position B of the auxiliary cap body 3 is regulated. Then, the raised position B of the auxiliary cap body 3 is the mountain portion 3 of the stopper wall 25.
It is retained by the resistance of the stopper arm 25 to get over the 7, that is, the elastic restoring force of the stopper arm 25 and the auxiliary cap body 3. Therefore, when the auxiliary cap body 3 is rotated downward with an operation force larger than the riding resistance, the stopper arm 25 can be flexed together with the auxiliary cap body 3 again and the mountain portion 37 can be crossed over to the opposite side to the previous time.

FIGS. 10, 11 and 13 show the auxiliary cap body 3
The lock mechanism 39 which locks at the descending position A is shown. In these drawings, lock plates 40 are fixed by screws 41 to the inner surfaces of the left and right end portions of the chin cover portion 3a which overlap the outer surface of the main cap body 2 at the lowered position A of the auxiliary cap body 3. The lock plate 40 has a rectangular lock hole 40a in the center. A release key 43 housed in a release key housing hole 42 of the auxiliary cap body 3 is connected to the lock plate 40 via a leaf spring 44. That is, a mounting piece 44a formed at the base end of the leaf spring 44 is fixed to the lock plate 40 by a rivet 45, and a release key 43 is fixed to the tip end side of the leaf spring 44 by a caulking protrusion 46 which is integral therewith. At the tip of the leaf spring 44, a protrusion 4 that can enter the lock hole 40a by pressing the release key 43.
7 are formed.

On the other hand, lower limit stopper members 48 are fixed to the left and right outer side surfaces of the main cap body 2 with screws 50 together with a base plate 49 joined to the inner side surface of the main cap body 2. The lower limit stopper member 48 is a standing portion 48 a that rises from the outer surface of the main cap body 2.
And a guide portion 48b that bends forward from the upper end of the standing portion 48a. The tip of the guide portion 48b has a rear portion of the lock plate 40 when the auxiliary cap body 2 is rotated to the lowered position A. A slope 51 is formed to guide the end toward the upright portion 48a.

A leaf spring 52 connected to the base plate 49.
At the free end of the sleeve 5, the sleeve 5 fitted to the side wall of the main cap body 2 is attached.
A lock pin 54 that penetrates 3 and can be fitted into the lock hole 40a is fixed. This lock pin 54 is a leaf spring 55.
Of the sleeve 53 is urged to project from the outer end of the sleeve 53, and the rear end of the lock plate 40 passes through the front side of the projecting end when the auxiliary cap body 2 is rotated to the lowered position B. The slope 55 that allows the

When the auxiliary cap body 3 is rotated downward from the raised position B, the rear end of the lock plate 40 slides on the slope 55 of the lock pin 54, and the pin 54 is retracted into the sleeve 53. Then, the rear end of the lock plate 40 comes into contact with the rising portion 48a of the lower limit stopper member 48,
The lowered position A of the auxiliary cap body 3 is restricted. At this time, the lock hole 40a of the lock plate 40 and the lock pin 54 are aligned with each other, and the lock pin 54 is fitted into the lock hole 40a by the repulsive force of the leaf spring 52. In this way auxiliary cap body 3
Is locked in its lowered position A. Therefore, during operation of the vehicle, the auxiliary cap body 3 does not turn upward due to wind pressure, vibration, and the like. Then, in such a state, the auxiliary cap body 3 cooperates with the main cap body 2 to form a full-face type cap body, so that the jaw of the user can be protected.

Next, when the release key 43 is pressed from the outside, the protrusion 47 causes the tip of the lock pin 54 to move toward the leaf spring 52.
Is pressed against the elastic force of the pin 54 to lock the pin 54 in the lock hole 40a.
The lock mechanism 39 is unlocked because the lock mechanism 39 is retracted. Therefore, in this state, the auxiliary cap body 3 can be rotated upward. When the auxiliary cap body 3 is held in the raised position B by the upper limit stopper member 33 as described above, the entire large window 4 of the main cap body 2 is opened, so that the user wears the cap body 1. Moreover, smoking, eating and drinking can be performed without being disturbed by the auxiliary cap body 3. At this time, since the shield plate 6 is connected to the auxiliary cap body 3 via the click stop mechanism 31, the shield plate 6 can rotate together with the auxiliary cap body 3, and it is not necessary to touch the shield plate 6 with a hand. Of course, when returning the auxiliary cap body 3 to the lowered position A, it is not necessary to operate the shield plate 6.

[0027]

As described above, according to the present invention, the main cap body having the large window with the lower edge opened on the front side, and the main cap body which is detachably fixed to the left and right outer side surfaces of the main cap body are held. A boss, which is rotated about the pivot axis between a lowered position in which the lower half of the large window is covered and an upper half thereof is used as a small window, and a raised position in which the entire large window is opened. Since the cap body is composed of the auxiliary cap body to be obtained, in the lowered position of the auxiliary cap body, a full-face type cap body can be composed of the main cap body and the auxiliary cap body.
A wide protection area can be secured for the user, and in the raised position of the auxiliary cap body, the entire large window of the main cap body is opened, so that the user does not wear the cap body like the jet type cap body. It's convenient because you can smoke, eat and drink.

Further, a shield plate is rotatably supported by the boss inside the auxiliary cap body to open and close the small window, and the boss is attached to the pivot shaft so as to sandwich the shield plate with the auxiliary cap body. Since one end of the piercing control plate is fixed to the auxiliary cap body, and a click stop mechanism that can hold the shield plate at an arbitrary rotating position is provided between the control plate and the shield plate, the shield plate is attached to the auxiliary cap body. Therefore, when the auxiliary cap body is rotated, it is not necessary to operate the shield plate, and the operation is simple.

Furthermore, since the control plate is provided with flexibility so that the control plate can be disengaged from the pivot shaft by bending the control plate from the other end side when the pivot shaft is removed from the main cap body, the pivot shaft is attached to the control cap. The shield plate can be attached and detached by an extremely simple operation of removing the shield plate from the body and bending the control plate, and therefore, the shield plate can be easily replaced with a new component.
