BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helmet mounting headset mounting mechanism mainly used by being mounted on a construction helmet.

[0002]

2. Description of the Related Art FIG. 4 shows a mounting mechanism of a helmet mounting headset in a first conventional example. In the figure, 8 is a helmet, 20 is a headset fixing arm having a bifurcated attachment portion 20a to the helmet 8, 21 is a screw screwed to one attachment portion 20a so as to be able to advance and retreat, and 22 is the other. Is a rubber sheet provided inside the mounting portion 20a. Thus, when attaching the helmet 8 to the helmet 8,
The headset fixing arm 20 is attached to the helmet 8 by screwing a screw 21 provided on the headset fixing arm 20 from the outside. The rubber sheet 22 is adhered to the headset fixing arm 20 and functions as a non-slip.

FIG. 5 shows a mounting mechanism of a helmet mounting headset according to a second conventional example. In the figure, reference numeral 24 denotes an alligator clip, and rubber 2 is provided inside.
3 are provided. In the following, the components denoted by the same reference numerals as those described above indicate the same elements, and the description will be omitted. In this conventional example, the helmet 8 is attached by the alligator clip 24 at the tip of the headset fixing arm 20.
, The headset fixing arm 20 is attached to the helmet 8. The rubber 23 is bonded to each of the portions of the crocodile clip 24 corresponding to the teeth, and functions as a non-slip as in the above-described conventional example.

FIG. 6 shows a mounting mechanism of a helmet mounting headset in a third conventional example. As is apparent from the figure, the first and second conventional examples are used in combination. A screw 21 is screwed below the crocodile clip 24, and the screw 21 is tightened after being attached to the helmet 8. Thus, the headset fixing arm 20 is not separated from the helmet 8 due to vibration or the like during work.

FIG. 7 shows a mounting mechanism for a helmet mounting headset according to a fourth conventional example. (A) shows a component configuration, and (B) shows an attached state. In the drawing, reference numeral 27 denotes a spring-shaped helmet clip having a substantially U-shape. A case 26 is provided at one end of the helmet clip 27, and a clip rubber 28 is provided at the other end.
Is covered. The case 26 and the headset arm 25 are connected. In use,
The headset is attached to the helmet 8 by “prying” the helmet 8 between the clip rubber 28 and the case 26.

[0006]

However, in the above-mentioned first conventional example, although it can be firmly fixed, it takes time and effort to turn and tighten the screw 21, and the head portion of the screw 21 is There is a problem that the appearance is impaired due to the structure that protrudes, and there are many design restrictions.

In the second conventional example, there is a trouble in that the crocodile clip 24 is pushed and opened with a finger each time and the helmet 8 is sandwiched in use. In addition, the strength of the crocodile clip 24 cannot be increased so much from the viewpoint of attachment. Therefore, there is a problem that the fixing force is weak and the mounting is unstable, and a part pressed by a finger protrudes larger than the brim of the helmet 8, so that there are many design restrictions.

In the third conventional example, since the fixing screw 21 is provided, the weakness of the fixing force in the second conventional example has been improved. In addition to the same problem as the conventional example, there is a problem that the structure becomes complicated and the cost increases.

Further, in the fourth conventional example shown in FIG. 7, since no screw is used, the design is good, but the helmet clip 27 has such a strength that it can be easily "pryed in". The fixing force is weak, unstable and impractical. In addition, a helmet clip 2 that does not cause any problem in practical use
With a strength of 7, mounting becomes extremely difficult, requiring "knack" for mounting, or a person with weak hands cannot mount. It is particularly difficult for women and children to attach. In addition, it is difficult to attach it to the desired position to
There is a problem that it is difficult to adjust the mounting position of the helmet 8. Further, conventionally, a clip rubber 28 having a high frictional resistance such as rubber is adhered or covered on one or both sides to stabilize the mounting. It is hard to put in. However, there is a problem that the attachment state becomes very unstable unless a member having high frictional resistance is attached.

[0010] The present invention has been made in view of the above points, and can be easily attached to and detached from a desired mounting position with a small force, and can be stably fixed by strong mounting. An object of the present invention is to provide a headset mounting mechanism.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the basic concept of the present invention will be described.
That is, an excellent mounting structure is realized by solving the problem of the conventional "pry-in" method shown in FIG. Therefore, the mounting mechanism of the helmet mounting headset has a U-shaped deformed helmet clip, a helmet clip made of a spring bar, and a helmet clip that is firmly attached to the helmet. Strength, one side of the helmet clip (the part that touches the inner surface of the helmet)
Attach a plastic part (clip cover) close to the inner shape of the helmet, cover it with a piece of high frictional resistance (clip rubber), and completely attach the helmet to the helmet clip at the desired position. There is a gap (space) that can be inserted, and between the tip of the helmet clip (the tip on the side that presses the outer surface of the helmet) and the helmet, there is a gap where a part of the headset side (a part of the clip case) enters. The helmet was made of a material with high friction resistance inside the helmet, while the clip case was made of a hard material and the friction resistance was reduced to make it easier to slide between the helmet and the clip .

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1A shows an attachment mechanism of the helmet mounting headset. FIG. 1B shows the helmet mounting headset without the stopper member, and FIG. 1C shows an example of the helmet clip and its related members. . In the drawing, reference numeral 1 denotes a clip case made of a hard material. The clip case 1 has an upper opening 1a as a through hole of a stopper knob 2b described later on an upper part and a through hole of a helmet clip 3 described later on a lower part. And a lower opening 1b. Further, a projection 1c as a movable guide of a stopper knob 2b and a projection 1d as an engagement portion of the stopper 2a, which will be described later, protrude from an inner wall of the clip case 1. Further, a groove-shaped headset mounting portion 1e having an uneven portion and a case taper support member 5 are provided inside the clip case 1. A case taper 4 for moving the helmet clip 3 while sliding is formed on a part of the case taper support member 5 provided below the inner wall of the clip case 1. The boundary surface between the right side (right side in the figure) and the lower side (lower side in the figure) of the clip case 1 is curved so that the clip case 1 can easily slide on the outer surface of the helmet. A gap between the clip case 1 and a clip rubber 7 described later is indicated by a symbol g, and a helmet is interposed in the gap g.

Reference numeral 2 denotes a stopper member made of a resilient material and attached to the inside of the clip case 1 at an angle. The stopper member 2 includes stopper portions 2a and 2a.
A stopper knob 2b and a clip holding portion 2c are formed. The stopper portion 2a is a substantially U-shaped concave portion for stopping and holding the clip end 3a of the sliding helmet clip 3 at an appropriate position. The stopper 2a is engaged with the protrusion 1d. The stopper knob 2b is the tip of the stopper member 2 (upper in the figure)
Is provided on the stopper portion 2a.
The tip protrudes outside from the upper opening 1a so that an operation for releasing the stopper function can be performed. The clip holding portion 2c has a hook shape provided at the rear end (the lower side in the figure) of the stopper member 2, and prevents the helmet clip 3 and the clip case 1 from being separated.

Reference numeral 3 denotes a helmet clip having a spring property and having a substantially U-shape when viewed from the side. One end 3a of the clip is one end of the helmet clip 3 and is inserted into the clip case 1. At a position slightly away from the clip end 3a, there is a substantially bent-shaped clip bent portion 3b, and the helmet clip 3 between the clip end 3a and the clip bent portion 3b (including the clip bent portion 3b).
Moves while sliding on the case taper 4 in the clip case 1. A clip cover 6 having a shape close to the inner surface of the helmet and a clip rubber 7 having high frictional resistance are attached to the other end 3c of the helmet clip 3, which is the other end of the clip. The operation procedure when attaching and detaching the clip case 1 to and from the helmet will be described with reference to FIG.

FIGS. 2A to 2D show the procedure for mounting the helmet mounting headset by the mounting mechanism. In these figures, 8 is a helmet. In (a), the clip end 3a of the helmet clip 3 is moved to the vicinity of the clip holding portion 2c, and the gap g between the clip case 1 and the clip rubber 7 is increased as much as possible. The insertion of the helmet 8 is started by inserting the edge of the helmet 8 into the gap g. In (b), the clip rubber 7 is arranged at a position where the helmet 8 to be attached comes into contact with the helmet clip 3, and the clip case 1 is slid in the direction of the arrow while holding the helmet clip 3 so as not to move. In (c), the helmet clip 3 slides on the case taper 4 as the clip case 1 moves. The clip case 1 is slid until the clip end 3a completely enters the stopper portion 2a. In (d), the clip case 1 does not return in the opposite direction due to the stopper portion 2a. When removing the clip case 1 from the helt 8, the stopper knob 2 b is pushed down to the helmet 8 side with a finger and the stopper portion 2 a
Is released, and the clip case 1 is slid in the direction opposite to the direction at the time of attachment.
