Description

[Detailed Description of the Invention] The present invention relates to a helmet visor mounting structure.

2. Description of the Related Art Conventionally, in helmets worn by drivers of motorcycles and the like, there are helmets in which the front side of the cap body is open and a visor is attached along the upper edge of the open part. The visor of this helmet is secured to the cap body through a plurality of hook buttons, and its mounting position, ie, height, is fixed.

By the way, drivers of motorcycles take various driving postures, for example, some take a posture with their upper body leaning forward, while others take a posture with their upper body upright. If you lean forward and the eaves of the helmet you are wearing are fixed at a low position, your visibility may be obstructed by the eaves of the helmet you are wearing. If the eaves are fixed at a high position, the eaves will no longer function effectively as a sunshade.

Problems caused by fixed eaves like this are exacerbated under severe driving conditions such as in trial competitions, so it is important to be able to adjust the height of the eaves as necessary, such as course conditions. is desperately needed.

The technical object of the present invention is to make it possible to adjust the height of the eaves up and down with a simple structure in response to the above-mentioned demands.

The structure of the present invention that achieves the above technical problem is that both the left and right ends of the canopy are rotatably supported on the cap body via set screws, and a locking convex is formed on one of the intermediate part of the canopy and the circumferential surface of the cap body. A locking protrusion and a locking recess are provided on the other side, and one of the locking protrusions and the locking recesses is made singular and the other is plural and arranged vertically in series, and the protrusion and the recess are selectively fitted. The eave is fixed to the cap body so that its height can be adjusted.

In the configuration of the present invention, the locking protrusion and the locking recess are provided on either the eaves or the cap body, but the reason is that it is desired to avoid providing the concave portion in the cap body as much as possible to avoid a decrease in strength. It is preferable that the locking convex portion is provided on the cap body side.

In addition, one of the locking protrusions and the locking recesses is made singular and the other plural, but in consideration of manufacturability, one locking protrusion is provided on the cap body, and multiple locking recesses are provided on the eaves, which is easy to process. It is preferable to provide the following.

According to the configuration of the present invention, the canopy is rotated up and down using its both ends as fulcrums, and the locking protrusion and the locking recess are selectively fitted together to lock the canopy to the cap body. As a result, the height of the eaves can be adjusted up and down, and it has a simple structure by fitting the concave and convex portions, making it possible to improve usability compared to the conventional structure in which the mounting position is fixed.

Embodiments of the present invention will be described below with reference to the drawings.

The eaves mounting structure of this example is shown in Figures 1 and 2.
As shown in the figure, in a jet type helmet A in which the front surface of the cap body a is open, a canopy b is attached along the upper edge of the open part 1 so that the height can be adjusted.

The visor b is made of a synthetic resin material such as polyethylene, and includes a flange piece b ₁ that projects forward of the cap body a, and this flange piece.
The attachment piece b ₂ stands up from the rear edge of the cap body b ₁ and is curved along the circumferential surface of the cap body a.

The mounting piece b ₂ is rotatably supported at both ends by the cap body a via resin setscrews 2, and this support structure allows the eaves b to rotate up and down. .

The set screw 2 is loosely fitted into a long hole 5 formed in the mounting piece _b2 , and this fitting allows the eaves b to slide back and forth.

A rectangular locking part b3 extending in the vertical direction is integrally formed in the middle part of the mounting piece _b2 , and a _{plurality of, for example, four locking recesses 3 are} vertically arranged in series on the back surface of the locking part b3. It is provided. The locking recess 3 engages with a locking protrusion 4 provided on the circumference of the cap body a to lock the canopy b to the cap body a. There is.

The locking convex portion 4 connects the male side member of the hook button to the cap body a.
The four locking recesses 3 of the locking portion _b3 are selectively fitted into each other. In FIG. 1, the locking protrusion 4 is fitted into the uppermost locking recess 3, and in this state, the height of the eaves b is set at the lower limit position.

In the helmet A which employs the eaves mounting structure of this embodiment as described above, the height of the eaves b is adjusted as follows. That is, with the eaves b shown in FIG. 1 set at the lower limit position, first loosen the set screw 2, pull the eaves b forward to disengage the locking recess 3 and the locking protrusion 4, Then, the eaves b is slid forward to a position where the locking portion b ₃ does not come into contact with the locking convex portion 4 . Then, by rotating the eaves b upward using both ends of the mounting piece b as fulcrums, and fitting the locking recess ₃ below the uppermost locking recess 3 in the locking part b 3 into the locking protrusion 4. , the height of the eaves b is set higher than the lower limit position.

When the lowest locking recess 3 of the locking portion _b3 is fitted into the locking protrusion 4, the eaves b is set to the upper limit position.

In this way, by selectively fitting the locking protrusion 4 and the locking recess 3 together, the height of the eaves b can be adjusted up and down.

After adjusting the height of the eaves b, the set screw 2 is tightened again to fix the eaves b.
