Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a headband of a helmet.
[0002]
[Prior art]
In general, as shown in FIG. 8, the helmet is equipped with interior members such as a hammock M and a headband H inside the helmet shell K to protect the wearer's head from impact.
[0003]
Since the conventional headband H is configured to hold down the wearer's forehead, the movement of the facial expression is restricted and the headband H is in a very cramped state. In particular, even if the eyes are turned upward in order to confirm the upper direction, the so-called upper-level expression becomes tight. As a result, there was a risk of leading to an accident due to a tendency to neglect the necessary upward confirmation. In addition, due to the pressing of the forehead by the headband H, heat builds up in the helmet shell K and it feels very annoying. In order to avoid this annoyance, trying to let the forehead touch the air, it became a so-called Aida cover, and consequently promoted dangerous wearing. Further, when the helmet is worn, the headband H at the forehead position can be seen from the front, which causes problems such as unsightlyness.
[0004]
In addition, the conventional headband H has a shape in which a portion corresponding to the head thereafter is straight or curved downward in an arc shape. In the straight shape, when trying to fit the headband H closely to the head, the buckle part B which is the hardest part contacts the back of the head, or both side parts of the buckle part B float ( I was away from my head) and the feeling of the occipital region and the feeling of holding by the headband H were bad. On the other hand, when the wearer is looking straight ahead, it feels like it fits closely to the back of the head when the wearer is looking straight ahead. The headband H is caught on this part, thereby causing discomfort such as the helmet itself being displaced forward and the buttocks of the helmet are also lowered, making it difficult to confirm upward.
[0005]
Further, when adjusting the covering depth of the conventional headband H, the hook Y connecting the hammock M and the headband H is once extracted, and then the covering depth is adjusted, and then again. I had to reattach 鋲 Y, and it took a lot of time and effort.
[0006]
Further, the conventional headband H has, as its size adjusting means, a large number of holes drilled in the size adjusting portion S at one end of the band fitted into a protrusion formed on the buckle B at the other end of the band. Since it is configured to match, the adjustment pitch is coarse and fine adjustment cannot be performed. Conventionally, there is a saw-tooth type with a fine adjustment pitch as a means for eliminating this drawback, but since the saw-tooth protrudes from the surface, there is a problem that it is easily damaged or dirty.
[0007]
Further, the size of the conventional headband H is generally adjusted by a method of pushing the size adjusting portion S into the buckle B. However, the size adjustment part S is usually made to have low rigidity and high flexibility in order to improve wearing comfort, so if you try to push it in, it will buckle and bend outward easily. As a result, it is difficult to adjust the size, and particularly for people with a large head circumference size, it is difficult to adjust the size and cannot be tightened.
[0008]
Further, the conventional headband H has a weak central portion at the center of the base of the buckle B, and there is a risk of cutting from this portion for some reason. For this reason, the structure has to be strong on both sides, and both sides are inevitably stiff in the longitudinal direction, which adversely affects the wearing comfort. On the other hand, even in the shape in which a large number of small hooks are arranged on both sides of the base of the buckle B, the strength of the base of each hook is insufficient, so this must be reinforced, and as a result, becomes stiff in the longitudinal direction. It had an adverse effect on the wearing comfort. Furthermore, the hook-like thing lacked certainty also in the point which hold | suppresses a belt.
[0009]
[Problems to be solved by the invention]
The present invention has been made to solve the above-described conventional problems, and the object of the present invention is to provide a helmet headband that is safe, comfortable to wear, easy to operate, and good-looking. is there.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, H is a headband and is mounted in the helmet shell K via a hammock M. As is apparent from FIG. 2, the headband H is mainly composed of a band-shaped band body 1, a size adjusting unit 2 integrally provided on one end side of the band body 1, and the other end of the band body 1. A buckle portion 3 provided integrally on the side and a mounting piece 4 for attaching the band main body 1 to the hammock M are constituted.
[0012]
The band main body 1 is formed so that the central portion 1a extending from the front to the side is high in the attached state and is lowered from the side rear to the rear. Therefore, as is clear from FIG. 1, the lower edge of the central portion 1a of the band main body is positioned above the wearer's forehead, and the lower edge has a gap between the forehead and the upper edge. Since it can be worn so as to hold the forehead, it is possible to create a space that can accommodate the movement of the forehead and eyebrows when the wearer confirms the upper part. In addition, because the forehead has no feeling of close contact and cannot contain heat, it is possible to avoid annoyance. Furthermore, since the central part 1a of the band main body 1 is difficult to see from the lower edge of the helmet shell K, the appearance when worn is refreshing.
[0013]
As shown in an enlarged view in FIG. 3 (A), the longitudinal direction is on the inner surface side of the size adjusting unit 2 (the side facing the head of the helmet wearer and the back side in FIG. 3 (A)). A large number of engaging teeth 2a are formed along the line. As shown in FIG. 3C, the engaging tooth 2a has a saw-tooth shape in which the band main body 1 side is formed on the vertical surface 2a 'and the outer end side is formed on the inclined surface 2a ". 3B, the engaging teeth 2a are configured to be retracted from the inner surfaces 2b ′ of the side edge portions 2b of the size adjusting portion. There is very little possibility that 2a directly contacts a human body, an obstacle, etc. As a result, loss of engagement teeth 2a, adhesion of dirt, etc. can be effectively prevented, as is apparent from FIG. A finger hook 2c protrudes from the outer surface of the tip of the size adjuster 2. In order to make it easier to hook the fingertip on the finger hook 2c, a hole 2d may be opened.
[0014]
As shown in an enlarged view in FIG. 4A, the buckle 3 mainly includes a substrate portion 3a, a guide piece 3b, an engagement tooth 3c, and a push portion 3d. As is apparent from FIG. 4B, the guide piece 3b forms an insertion passage 3b 'for slidably guiding the size adjusting portion 2 between the guide piece 3b and the substrate portion 3a. A plurality of engaging teeth 3c are formed on the substrate portion 3a between the guide pieces 3b. As shown in FIG. 5, the engagement teeth 3 c mesh with the engagement teeth 2 a of the inserted size adjusting unit 2. The engaging tooth 2a is also formed in a saw-tooth shape, and its vertical surface and inclined surface are formed in the opposite direction to the vertical surface 2a 'and inclined surface 2a''of the engaging tooth 2a of the size adjusting portion 2. As a result, both the engaging teeth 2a and 3c can move in the direction in which the annular headband H is tightened (X direction), and are locked in the direction in which the annular headband H is tightened (the opposite direction of X). Therefore, the fingers 2c at the tip of the size adjusting unit 2 and the guide piece 3b of the buckle 3 are respectively hooked with fingers of both hands and tightened by pulling both ends of the headband H. Can do.
[0015]
As shown in FIGS. 4A and 4B, a finger hook piece 3b ″ is projected from the guide piece 3b on the end side, and the finger hook pieces 3c formed at the tip of the size adjusting section 2 The finger straps 3c and 3b ″ are respectively hooked with fingers of both hands, and the end portions of the size adjusting portion 2 and the buckle portion 3 are pulled away from each other to adjust the tightening of the headband H. As described above, since the headband H is tightened by the pulling operation, the size adjusting unit 2 is not bent (curved) in the middle even if the head circumference is large, and the rigidity of the size adjusting unit 2 is increased. Since it is not necessary to make it hard, it can softly hit the back of the head and improve the wearing comfort.
[0016]
In FIG. 4 again, the push portion 3d is located on both sides in the width direction of the substrate portion 3a with a gap therebetween, and both ends thereof are integrated in a bridge shape. The push portion 3d is formed with a curved portion, and a central portion thereof is easily bent inwardly. A wedge portion 3d 'is provided inside the center of the push portion 3d. A slope is formed on the lower surface of the wedge portion 3d ', and a slope is also formed at a corresponding portion of the substrate portion 3a. A flat pushing piece 3d ″ is provided outside the center of the push portion 3d so that the push portion 3d can be easily pushed with a finger or the like. The pushing piece 3d ″ is pushed by the pushing force of the finger. It is connected to the main body of the push part 3d via the central neck so that it can be concentrated in the center of the part and bend effectively. When the two push portions 3d are pushed in the mutual direction, the size adjusting portion 2 is lifted by the inclined surface of the wedge portion 3d ', and the engaging teeth 2a are separated from the engagement with the guide piece 3c of the buckle 3.
[0017]
As is apparent from FIG. 2B and FIG. 5, the size adjusting unit 2 and the buckle unit 3 are curved upward in an arc shape. Therefore, when the wearer turns his head upward, contact with the neck can be avoided, so that the upward confirmation can be performed without hindrance, and work safety can be improved. Moreover, since a back head can be easily hold | suppressed with the whole size adjustment part 2, a feeling of fitting can be improved. Furthermore, as will be described later, by appropriately adjusting the covering depth, the advantage of the shape curved upward in the arc shape can be utilized to the maximum, so that the covering comfort can be further improved.
[0018]
As is clear from FIG. 6A, the mounting piece 4 is formed with a plurality of holes 4a arranged in the vertical direction, and these holes 4a are communicated with each other through slits 4b. A hook-like connector 5 protruding from the hammock M is passed through the hole 4a to connect the hammock M and the headband H. The connector 5 may be provided separately from the hammock M. Therefore, the headband H can be adjusted up and down by using the fitting of the slit 4b so that the headband H can be easily adjusted to the optimum position for the wearer. In addition, when the helmet shell K is moved up and down when the shock is absorbed, the covering depth adjustment function moves vertically, thereby reducing the burden on the wearer's ear.
[0019]
4A and 4D, belt pressers 3e are formed on both sides of the base portion of the buckle portion 3, and a slit 3e 'is formed between the substrate portion 3a. Therefore, in the base part of the buckle part 3, the belt presser 3 e can be given flexibility without lowering the strength due to the presence of the central part 3 a, so that it can be compared with the conventional one described in [0008]. Can be applied softly to the back of the head. Further, since the belt presser 3e is plate-like, the size adjusting unit 2 can be pressed down more reliably than a conventional hook-like one.
[0020]
FIG. 7 shows another embodiment of the belt retainer, 3f is a belt retainer, 3f 'is a slit, and is formed smaller than the belt retainer 3e of the embodiment of FIG. By pushing 2 from the outside, it can be easily and quickly latched.
