Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a structure for mounting a shield on a full-face type or jet type safety helmet used when riding a motorcycle, automobile, or the like.

(Prior Art) In conventional shield mounting structures for full-face type and jet-type safety helmets, the opening adjustment means and the shield are generally screwed to the helmet body. That is, the left and right side parts of the shield and the opening adjustment (ratchet mechanism) parts are fixed via the shield mounting cover.

Therefore, with the above-mentioned conventional structure, if the shield mounting part is disassembled during touring because the opening/closing (rotation) of the shield becomes difficult, remove the set screw and attach the shield mounting cover to the cap body. If the shield is removed, various parts for opening and closing the shield may fall apart, and problems such as damage may occur if parts are lost.

(Object of the Invention) In view of the conventional circumstances as described above, an object of the present invention is to provide a mounting structure that can securely hold a shield on a cap body without using a set screw.

Another object of the present invention is to provide a mounting structure that prevents the shield retainer cover from separating from the cap body and falling off.

(Structure of the Invention) The technical means taken by the present invention to achieve the above-mentioned object is to provide a substrate having an annular protrusion protruding from the left and right outer surfaces of the cap body to rotatably support the left and right sides of the shield. It is fixed with screws, and the shield holding cover is rotatably attached to the board with a hinge structure.
The holding cover can be freely engaged with and removed from the board by a snap action, and is further characterized in that the board or the shield holding cover is provided with a stopper for regulating the upper limit rotation position of the shield.

One member constituting the moderating means is formed on the periphery of the rotary support portion of the shield, and the other member constituting the moderating means is formed on the substrate or the shield holding cover.

Further, the rotary support portion of the shield may be integrally formed with the shield, or a molded product formed separately from the shield may be integrated with the shield by fixing means such as caulking.

Furthermore, the shape of the cap body equipped with the shield may be either a full-face type or a jet type.

(Function) According to the above configuration, the shield rotates around the annular protrusion of the base plate fixed to the cap body, and the rotation is caused by the rotation of the shield when the peripheral edge of the rotary support part of the shield hits the stopper formed on the base plate or the shield holding cover. By matching, the upper limit position of the shield's opening movement is determined. When the shield is rotated, it is controlled in a controlled manner by a moderation means provided opposite the periphery of the shield's rotation support and the board or the shield holding cover, and the shield is rotated in stages between fully closed and fully opened. is supported.

Moreover, since the shield holding cover is rotatably connected to the board with a hinge structure, even if the shield holding cover is disengaged from the board in order to remove the shield from the board (cap body), the shield holding cover will remain attached to the board. Because it is connected with a hinge structure,
The shield presser cover does not come apart.

(Embodiments) Hereinafter, embodiments of the present invention will be described based on the drawings. 1 is a cap body, 2 is a shield, 3 is a substrate fixed to the left and right outer surfaces of the cap body 1, and 4 is a shield holding cover. .

The cap body 1 has a full-faced shape that is generally well known today, and has a window hole 5 in the front, and shields 2 for opening and closing the window hole 5 are located on the left and right outer surfaces of the cap body 1. The board 3 and the shield holding cover 4 are fixedly attached to each other so as to be vertically movable.

The substrate 3 that rotatably holds the shield 2 is formed into a flat plate made of synthetic resin, and rotation holes 11 and 11' opened at the left and right sides of the shield 2 are fitted into one surface of the flat plate. An annular protrusion 6 to be fitted is formed protruding from the same body, and a protrusion 7 for regulating the upward rotation range of the shield 2 is provided on the radially outer side of the annular protrusion 6. The substrate 3 is fixedly fixed to the cap body 1 with a plurality of setscrews 8.

The set screw 8 in the board 3 has a hole 20 having a diameter larger than the axial diameter of the set screw 8, so that the mounting position of the board 3 can be adjusted.

Further, a shield holding cover 4 having the same shape as the board 3 is connected to one side of the board 3 so as to be openable and closable by a hinge structure using a pin 12, and an annular protrusion of the board 3 is attached to the inner surface of the shield holding cover 4. A protruding ring 9 that fits relatively with the part 6 is formed in the same body, and the shield holding cover 4 is held against the board 3 by the snap action of both parts.
The closed state is locked and held.

Furthermore, a protrusion 10b is formed on the inner surface of the shield presser cover 4 and comes into contact with a concave-convex engaging piece 10a, which is one of the moderating means 10 formed on the outer periphery of the rotation holes 11, 11' of the shield 2. When the cover 4 is closed, the uneven engagement piece 1 of the shield 2
The protrusion 10b engages with the shield 0a, thereby moderating the rotation of the shield 2. The moderating means 10 of the shield 2 is not limited to being formed facing the shield 2 and the shield holding cover 4, but may be formed between the shield 2 and the substrate 3, or as shown in the figure. It is not limited to the structure of

Furthermore, the rotation holes 11, 11' are opened on both the left and right sides of the shield 2, and the rotation center portion, which has the concave and convex engaging piece 10a, which is one of the moderation means 10, formed on the outer peripheral edge of the shield 2, as shown in the figure, In addition to forming the shield integrally, it is also possible to separately mold only the rotation center portion and integrally connect and fix it to the left and right sides of the shield by caulking or the like. Further, a locking mechanism 13 is provided between the board 3 and the shield presser cover 4 to prevent the shield presser cover 4 from opening.

The latching mechanism 13 includes a latching hole 15 formed from the side in a projecting portion 14 that is integrally provided on the substrate 3, and a shield holding cover 4 that is fitted into and removed from the latching hole 15.
The stopper 16 is arranged on the side, and the stopper 16 can be engaged and disengaged by sliding an operating knob 17 provided on the outside of the shield presser cover 4. The stopper 16 is a rectangular flat plate, and the upper surface of the tip that is inserted into and removed from the latching hole 15 is formed with a notch in an inclined surface, and the other side (rear part) has a spring in the direction that the stopper 16 is always inserted into the latching hole 15. A spring acting piece 18 that generates and biases is formed to protrude in the shape of an arrow, and the spring acting piece 18 is fitted into a guide frame 19 that is formed so that its width becomes narrower toward the rear. moves in the narrow direction within the guide frame 19, the spring action piece 18 is pressed inward, elastic force is accumulated, and
When the moving force is released, the stopper is moved in the direction of fitting into the locking hole 15 by the accumulated elastic force,
The shield presser cover 4 is automatically engaged and prevented from opening.

With the above configuration, the shield 2 can freely rotate in the vertical direction about the annular protrusion 6 of the substrate 3, and the upper limit of the rotation is controlled by one of the moderation means 10 formed on the periphery of the rotating part of the shield 2. This is done by abutting the side end of the uneven engagement piece 10a against a protrusion 7 provided on the substrate 3, and the shield 2
Within the rotation range of , the uneven engagement piece 10a and the projection 10b
moderation is imparted to the rotational movement. The shield 2 is held down by a shield holding cover 4 connected to the base plate 3 in a hinge structure, so that it does not come off from the cap body.

In addition, the annular protrusion 6 and the protrusion 9 fit together with the board 3 with a snap action, so that the opening movement of the shield holding cover 4 is stopped and the shield holding cover 4 is separated from the cap body (board). It will not separate and will be held together.

(Effects of the Invention) Since the shield mounting structure of the present invention has the above-described configuration, the shield can be mounted without using set screws, and with the substrate fixed to the cap body.
It can be engaged and supported by a shield holding cover connected to the board with a hinge structure, and can be mounted so as to be rotatable with moderation.

Moreover, since the engagement support is held by the annular protrusion of the board fixed to the cap body and the shield presser cover which is connected to the board so that it can be opened and closed, even if the shield presser cover is opened to remove the shield, the support remains. I have never had any problems with the shield popping out in pieces, so I can attach and detach the shield with confidence.

In addition, since the board that holds the shield and the shield holder cover are connected by a hinge structure, there is no need to worry about the shield holder cover being separated or lost, and you can work with peace of mind. Because they are connected and integrated, it is very convenient for parts management.
