Description

[Detailed Description of the Invention] The present invention provides a shield member? The present invention relates to a helmet that can be held in a desired opening/closing position, and particularly to a helmet that can be held in a desired opening/closing position, and particularly relates to a helmet that can be held in a desired opening/closing position.

The opening/closing mechanism of the shield member in the Kono type helmet is as follows:
It must be able to withstand vibrations and wind pressure when worn, and be able to be held in the open/closed position reliably, especially if the mechanism allows the member to be held at a desired position between the open/closed positions. Although its holding function is important, the opening and closing operations of this shield member are often performed when driving while wearing it.
It is highly desirable to be able to easily open and close the opening and closing operations.

In the present invention, the shield member can be held at a desired closed position and can be closed all at once from the open position by a one-touch operation. - Full mechanism provided.

An embodiment of the helmet of the present invention shown in FIG. 1 will be described in detail below.

FIG. 1 is a front perspective view of the entire helmet of the present invention. A window 2 is provided on the front side of the cap body 1. A shield member 4 made of a curved flexible synthetic resin plate with transparent or ultraviolet-absorbing colored syllables is rotatably pivoted at both ends of the window 2 in the cap body l by means of first fixing screws 3. It's a dress. Furthermore, the pivot portion of the shield member 4 of Amakko? The entire end including the cover 5 is covered.

In this cover 5, the first fixing screw 3 is used as one of the screws to attach to the cap body l, and the second fixing screw 6 is further attached integrally to the cap body. Reference numeral 7 denotes an operating member, which is slidably attached to a part of the outer wall of the cover 5.

That is, this operation member 7 (l-j: as shown in FIG. Further, a part of the trap slide groove 5a is drilled, and the slide groove 5a' is passed through the horizontally bridging presser member 9 to the slide metal fitting 8' through the interposition of a slideable member 8 that fits with the half-mounted part of the trap slide groove 5a. It is attached to the rear surface of the operating member 7 with a fixing screw 17. Reference numeral 11 is a pressure expansion spring that biases the operating member 7 so that it is always in the raised position. It is provided between the groove 5a and the lower end of the groove 5a.

As shown in FIG. 3, the shield member 4 has a metal fitting at the end of the pivot point connected by the first fixing screw 3, all of the engagement recesses 10 are connected to each other on a circle concentric with the entire center of the pivot point. 4a? They are integrally superimposed.

Reference numeral 12 denotes a lever whose one end is rotatably supported on the inner wall of the cover 5, and is curved in an arc and has grooves 13' formed in the intermediate region and the tip region of the rod. In the groove 13 of this lever 12, in its intermediate region, there is a curved and folded head a, flat shoulders on both sides of the head a, and both shoulder parts, respectively, and an extended open leg part C.
With the spring engaging member 14 consisting of . It is a insert box that can be inserted in between. Also, the reno<
- 12 has the slide fitting 8 in its groove 13.
The sliding bottle 16 is fully fitted in the upright position.

In the above configuration, one end of the lever 12 is pivoted to the entire cover 5 side in consideration of the convenience of assembly work, but this lever 1
The one end pivot of 2 is not limited to the cover 5 side, but may be on the cap l side. Furthermore, the spring locking member 14 is also elastic for reasons that will be explained later. In the helmet of the present invention having such a structure, a mere claw-like locking member may be used.

The cover 5 is equipped with the operating member 7, its related members, and the spring locking member 14, and the round lever 12 and the like are assembled in advance.
On the other hand, the metal fitting 4a'? With both ends of the shield member 4 with the shield attached facing the pivot position of the shield member 4, remove the cover 5.
Completely cover the cover 5 and fix the upper part of the cover 5 while fully attaching the shield member 4 with the first native screw 3.

Next, the lower part of the cover 5 is completely fixed using the second native screw 6, and the assembly is completely completed. At this time.

As shown in the second figure, the head a of the spring locking member 140 is in a positional relationship in which it fits into the engagement recess 10 on the edge of the shield member 4.

When in use: ii: An arbitrary position of the shield member 4.

For example, in order to flip up the window 2 from the fully closed position shown by the solid line in FIG. 2 to the fully open position shown by the chain line in the figure,
The member 4 is operated by hand to push the box upward. With this operation, the engaging recess 10 on the edge of the member 4 moves clockwise in FIG. . Therefore, the head a is pushed toward the groove 13 by the deformation caused by the bending of the shoulders and the expansion of the legs C. By Koku.

The end edge fully crosses this head a, and when the primary engagement recess 10 approaches the area of the head a, the head a protrudes due to the elasticity of the member and engages with the retaining opening 10. .

That is, the engagement recess lO and the head a of the spring locking member 14
Due to the click action of
By stopping the member 4 in the flip-up position by the pushing member 4 in the middle of the flip-up operation, the member 4 is gradually moved to the engagement position between the engagement recess 10 and the head a of the spring locking member 14. It can be held in a desired position, and this operation is also possible when going from the flip-up position to the closed position.

The closing operation of the shield member 4 from the raised position to the fully closed position of the window 2 can be performed completely at once by the unique mechanism of the helmet of the present invention. That is, when the shield member is flipped up as shown by the chain line in FIG.
When pushed downward against the acting force of 1, the sliding fitting 8 and the sliding fitting pin 7c, which are integrated with the holder, are implanted into the holder, and the sliding fitting pin 16 is cut 1), so that the pin 16 is fully grooved. The lever 12 fitted in the tip region of the lever 13 rotates counterclockwise in the figure about the pivot point at the other end. As a result, the lever 12
The head a protrudes into the intermediate region of and fits into the engagement recess 10.
71. is withdrawn from the fitting region with respect to the recess 10, so whether the holding state is completely released or not. The shield member 4 rotates all at once and returns to the fully closed position W.

The return of the shield member 4 may be performed by its own weightb1.Furthermore, in order to perform this action rapidly, it is necessary to work between the member 4 and the cap body l or the cover 5 in the direction of the pivoting movement (the suspension springs are all attached). It is valid.

When the operating member 777 is released, the member 7 returns to the position shown by the solid line in FIG. Return to

Here, since the biasing force of the pressure expansion spring 11 acts on the lever 12 via the sliding pin 16, the head a protruding from the lever 12 is pressed into a claw-like shape that is integral with the lever 12, for example. In the case of a projection, the lever 12 and the operating member 7 are slid and rotated against the biasing force of the expansion spring 11 so that the engagement recess 10 moves over the entire claw-like projection. It is possible to do so. Also, what about the edge configuration of the shield member 4 and the force attached to the operating member 7? <-5 may be provided at both ends of the window 2 of the cap body 1, but 1
Achieving the intended purpose of the helmet of the present invention (In this case, it is effective to provide the shield member only at one side end.) Thus, the helmet of the present invention has a shield member with an engaging A trap locking member provided on the concave portion and a lever pivoting at one end is fitted to hold the shield portion in its rear position, and the locking member is held by operating an operating member from the outside. Since the mating action area is set back from ≧, it is possible to hold the shield sound B material in the desired open position, and it is possible to return the window to the fully closed position all at once. Therefore, it is extremely convenient to operate the shield member when driving the helmet N, and it is of great practical importance.

Similarly, the operating direction of the operating member in the helmet of the present invention is not limited to the vertical direction as in the illustrated embodiment, but can easily be configured in any direction such as horizontally.
