Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shield screen attachment device for a helmet.

A conventionally known one is as shown in Fig. 1, where A is a helmet, B is a window thereof, and C is a shield screen for window B. Since they were attached in close contact with each other, it was not possible to move the shield screen C up and down about its axis E smoothly.

The present applicant has already pointed out this point and proposed a mounting device that can move the screen forward and then upward F when installing a shield screen on a helmet, but the prior application's However, in order to move the screen back and forth, it must be done with both hands, creating the inconvenience of having to stop the vehicle.

Therefore, the present invention has been devised, in which a shield screen is attached to the front of the window formed in the helmet, and the screen is attached only freely to rotate on either the left or right side, and the other side is attached to rotate freely and rotate forward and backward. This is an attachment device for a shield screen on a helmet that can be attached so that it can be freely accessed and removed.

To explain with a diagram, (1) is a helmet, and C2
) is the window, and (3) is the shield screen of the window. The screen (3) is rotatably attached to the helmet (1) on the left and right sides, for example, on the right side, by a shaft. However, the left and right sides of the screen (3), for example, are attached so that they can rotate and be moved forward and backward, and the helmet (1) has a fixed shaft protruding in the horizontal direction on the side surface. A fixed engaging body (6) is fixed to the fixed shaft α (a). The engaging body (6) has a perfect circular metal-like shape, and has several four parts (
9). An annular spring body (4), which is a part of the rotating engagement body (5), is fitted onto the outer periphery of the engagement body (6).

The spring body (4) is a ring-shaped spring body that surrounds the outer periphery of the perfectly circular fixed engagement body (6), and is cut at a part of its rear part, more precisely at an intermediate position between the top and bottom, Each of the cut portions has a convex portion GG that elastically engages with the four portions (9) formed on the outer periphery of the fixed engagement body (6).
form.

In front of the spring body (4) are a pair of upper and lower elastic legs +71.
+7+ is integrally formed to protrude forward, and engaging claws t81 and t81 protruding in ten pieces are respectively protruded from both upper and lower outer surfaces of the elastic legs [71+71.

However, the elastic legs f of the rotation engagement body (5) are attached to the shield screen (3) on the side where the rotation engagement body (5) is provided.
71 + Fix the box a to insert 71. The box 03 has inside thereof the upper and lower elastic legs [71+71] of the rotation engaging body (5), so that the upper and lower elastic legs [71+71] can be smoothly inserted.
Guide rail surfaces (17) are formed above and below. Depending on the degree of insertion, the engaging claw t formed on the elastic leg [71 [7]
An inlet side notch anαD′ and a back side notch groove (I (to) α3) with which 81 +81 engages are formed, respectively. Put your finger on the box α2 and install the shield screen (3).
A knob 151 is formed for moving the front and back. or,
The shield screen (3) is provided with a finger hook 00 for moving the screen (3) up and down.

Next, we will discuss the effect.

The normal usage condition is as shown in Figures 2 and 8, in which either the left or right side of the shield screen (3) is fixed to the helmet (1) with only rotational freedom; The upper elastic leg (7) and the lower elastic leg (7) of the rotating engaging body (5) are engaged with a box a2 fixed to the shield screen (3). That is, in a normal state, the upper and lower elastic legs +71 C71 of the rotation engaging body (5) are deeply inserted into the box, and the upper elastic legs (7) C71 protruding from both outer surfaces of the upper and lower elastic legs (7) C71 are deeply inserted into the box. After the engaging claw (8) and the lower engaging claw (8) slide an an' on the guide rail in the hook Oz,
The cut groove on the back side provided in the guide rail a7)17+
13) Each is engaged with Q3). Then, as mentioned above, the rotary engagement body (5) inserted into the box α2
), the part of the annular spring body (4) at the rear part of the rotating engaging body (5) is fitted onto the outside of the fixed engaging body (6) which is fixed to the helmet +11 via the fixed shaft α4. The convex portion a0 formed at the cut portion of the annular spring body (4) is connected to the four portions (9) formed on the outer periphery of the fixed engagement body (6).
), it is in a fixed state and stabilized in the states shown in Figures 2 and 8, and the inner surface of the shield screen (3) is in close contact with the front of the helmet [11], allowing it to be used without rain or wind entering. can.

However, if you hold the handle with one hand, and with the other hand hold the knob a51 of the hook 02, which is provided only on the left side of the shield screen (3), with your fingertips and pull it forward,
The cut groove Q31 on the back side of the guide rail [17] of the box [12] fixed to the shield screen (3) (the rotary engaging body (5
)'s elastic legs +71 +71's upper and lower outer engaging claws (81
[81, as the shield screen (3) is pulled forward, passes along the slope of the cut groove as a:i,
Each elastic leg +71 (71) is once compressed in the vertical direction, and the width of the elastic leg +71 (7) becomes smaller, and the guide rail lower fin formed in the box α2 becomes slidable. , shield screen (3)
When pulled forward, the upper and lower engaging claws (81+81) of the elastic legs +71 +71 reach the notch grooves Qll all on the entrance side, and the compressed elastic legs (71+71 expand due to elasticity, (full cut) engages with 0υ and
It will be in the state shown in the figure. Therefore, although only one side of the front surface of the shield screen (3) is distorted, a gap is formed to allow wind to enter. In this state, if you place your finger on the finger rest aO and lift it upward, you can easily adjust it to the state shown in FIG. 4.

In addition, when moving the shield screen (3) upward as described above, a plurality of convex portions aIaIII formed on the annular spring body (4] fi+ are formed on the outer periphery of the fixed engagement body (6). The four parts (91+91) are elastically moved step by step.

The present invention is as described above, and in particular, a helmet (
A shield screen (
3), the screen (3) is
The helmet shield screen mounting device is configured such that one of the left and right sides can be attached freely only by rotation, and the other is attached so that it can be rotated and moved forward and backward.
The shield screen can be smoothly operated because it has a structure in which it is first pulled out to the front and then moved up and down, unlike conventionally known shield screens that are forcefully moved up and down while contacting the front surface of the helmet. Further, the shield screen is not designed to slide back and forth on the left and right sides at the same time, but only one of the left and right sides is free to rotate, so the shield screen can be moved in and out of the front and back with one hand.

Therefore, while driving, you can operate the screen without interrupting driving. In addition, it has a simple structure, is easy to manufacture, and requires only parts on one side, so it has the effect of reducing material costs.
