DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helmet, and more particularly to a helmet provided with a chin band including a holding band and an operating band.

[0002]

Conventionally, in a chin band provided on a helmet, a base end of a holding band is attached to one of left and right side portions of a helmet body, and a stopper is provided on a distal end side of the holding band. A base end of an operating band is attached to the other of the left and right side portions of the helmet main body, and two D-shaped or substantially rectangular shaped stop rings are used as the stoppers to constitute the stoppers. The operating band is inserted into the two inner and outer retaining rings, and the operating band is folded back by the outer ring, sandwiched between the inner and outer rings, and pulled out from between the inner ring and the operating band. I am trying to tighten it. By the way, if the extra length of the operating band pulled out from the outer ring is left as it is, the extra length will hang down, and this extra length will oscillate due to the wind during traveling, etc. Problems such as generation of sound occur. For this reason, there is a method of inserting the extra length portion into a chin strap cover provided on the operation band side. However, since the length of the extra length portion varies depending on the user, there is a surface that is difficult to insert.

In Japanese Patent Publication No. 4-57766, one of male and female locking means is provided at the end of the surface of the operating band which comes into contact with the skin, and the other of the male and female locking means is held. A helmet fixed on the outer surface of the band for use (page 1, column 1, lines 7 to 10) has been proposed, and a hook button (page 1, left column, line 11) and a male / female locking means are provided. A surface fastener (page 1, column 1, lines 13 to 14 of the same publication) is used. In this helmet, for example, male / female locking means provided on the operation band and the holding band are locked, The rest of the extra length can be prevented.

However, in the helmet, the female button provided at the tip of the operating band is pressed against the male button of the holding band to engage and lock (page 3, column 5, lines 4 to 5 in the same publication).
The male / female button is locked so that the inner side of the tip of the holding band overlaps the male button position on the outer surface of the holding band. May not be possible. In addition, since the wearer of this type of helmet sometimes wears gloves and performs the band operation, the locking work of the male and female buttons and the like becomes complicated,
Also, unlike the bare hands, it is difficult to obtain a click feeling of the male and female buttons, and it is difficult to check the locked state. Furthermore, in the above-mentioned helmet, a retaining ring is attached to the folded portion of the holding band, and a male button is attached to the outer surface side of the holding band. To increase. In addition, the tip of the holding band is generally subjected to a fusing treatment by ultrasonic waves or the like, but in the helmet, since the tip of the operating band is exposed, appearance design is impaired, and furthermore, simply If only the fusing treatment is performed, the distal end side of the operating band is bent so as to be turned up by use, and it is expected that the subsequent male / female locking operation becomes difficult.

Accordingly, an object of the present invention is to provide a helmet capable of easily locking the tip of the operation band to the holding band side.

[0006]

According to a first aspect of the present invention, there is provided a helmet body, comprising: a holding band having a base in a longitudinal direction attached to one of the left and right sides thereof and having a stopper at a distal end; In a helmet equipped with a chin band including a longitudinal base end attached to the other end thereof and an operating band whose distal end is inserted into and engaged with the stopper, a locking cap is provided to cover the distal end of the operating band. A stopper ring for inserting and locking the locking cap is provided on the distal end side of the outer surface of the holding band, and the locking cap is engaged with a locking receiving portion provided on a base end side of the stopper ring. The operating claw is provided with a stop claw, and the operating band is inserted into and engaged with the stopper, and the locking cap provided at the end of the extra length of the inserted operating band is inserted and locked on the stopper ring. The extra length Without that hangs down, moreover,
Since the locking cap at the tip is inserted into the stopper ring and locked, the locking work can be easily performed regardless of the length of the extra length. A good click feeling is obtained when both are locked. Furthermore, the tip of the operating band is not exposed by the locking cap.

Further, according to the invention of claim 2, the holding band is inserted through the stopper and the stopper ring, the inserted distal end is folded back and overlapped, and the holding band of the overlapped portion is sewn to each other. The holding member and the stopper ring are provided on the holding band by a sewn portion which has been worn, and the overlapping portion of the holding band is sewn together with the stopper without separately attaching the stopper ring. Can be attached to a retaining band.

Further, according to a third aspect of the present invention, the stop comprises an inner and an outer stop ring, and a front end side of the holding band is turned up to form a front end ring, and the base end of the front end ring is formed. The sewing part is provided, and the inner ring,
An outer stop ring and the stopper ring are provided, and the stopper ring has an inner frame portion arranged inside the distal end ring portion and an outer frame portion arranged outside, and the length of the inner frame portion is set to the outer frame portion. The locking frame is formed shorter than the frame portion, and the locking receiving portion is provided on the outer frame portion. When the locking cap is inserted into the stopper ring, the locking claw portion of the locking cap locks the outer frame portion. Good click feeling is obtained by locking to the part. The inner and outer retaining rings and stopper rings
Since the inner frame portion arranged inside the distal end ring portion is formed shorter than the outer frame portion, the inner and outer frames are formed by sewing operation.
Even if the outer stop ring hits the stopper ring, the stopper ring does not tilt, and the subsequent operation of inserting and locking the locking cap can be performed stably. Also, by the spring action of the tip ring, the locking cap can be easily inserted and removed from the stopper ring,
Moreover, since the inner ring portion arranged inside the distal end ring portion is short, the distal end ring portion can be formed small, which is advantageous in enhancing the spring action of the distal end ring portion.

Further, according to a fourth aspect of the present invention, the stopper comprises an inner and an outer retaining ring, and the distal end side of the holding band is turned up to form a distal end ring, and the base end of the distal end ring is formed. The stopper portion is provided with the sewn portion, the inner and outer stop rings are provided on the distal end ring portion, and the sewn portions are provided on both longitudinal sides of the stopper ring. When inserted into the ring, the locking claw portion of the locking cap is locked to the locking receiving portion, and a good click feeling is obtained. In addition, since the stopper rings are provided separately from the inner and outer stop rings by the sewn portions on both sides, the stopper rings are not interfered by the operation of the stop rings, and are sewn close to both sides of the stopper rings. Since the portion can be provided, the stopper ring can be provided while being held upright.

A.

Next, the holding band 12 and the operating band
To explain the usage of 13, the helmet body 1 is mounted, the locking cap 31 at the tip of the operating band 12 is inserted from the inner surface into the retaining rings 19, 20 and pulled out. Fold it back to the side and insert it between the curved tips of the retaining rings 19 and 20, and reinsert it into the inner retaining ring 20 and pull it out, so that the operation band 13 is inserted and engaged with the retaining rings 19 and 20 and held. Band 12 and operation band 13 are connected in a tightened state. In this manner, when the operation band 13 is inserted and engaged, even if the base ends of the retaining rings 19 and 20 move in the distal end ring portion 12W, the inner frame portion 42 of the stopper ring 21 is narrow in the length direction. Therefore, it is less affected by the moving retaining rings 19 and 20. After insertion engagement,
Since the distal end of the operating band 13 is a free end and remains hanging, the retaining cap 31 is held along the length direction of the holding band 12 by holding the distal end of the operating band 13 and the stopper ring 21. Insert and lock into In this case, when the locking cap 31 is inserted between the outer frame portion 41 and the holding band 12, the locking claw 47 is caused by the elasticity of the stopper ring 21 and the bending of the distal end ring portion 12W of the holding band 12. When the stopper ring 21 is smoothly inserted into the stopper ring 21 and the locking step 49 of the locking claw 47 engages with the locking receiving portion 41A of the stopper ring 21, the elastic restoring force and the tip of the stopper ring 21 A good click feeling is obtained by the spring action of the ring portion 12W, and the outer frame portion 41 of the stopper ring 21 fits into the recess 51 of the locking cap 31. When inserting the locking cap 31 into the stopper ring 21, the distal end side of the operation band 13 inserted through and engaged with the retaining rings 19 and 20 is turned around so as to be folded back toward the holding band 12. The operating band 35 abuts on the outer surface on the distal end side of the band 13, and comes into contact with the distal end side in a state where the distal end side of the operating band 35 is bent. Since the tip side is curved, even if the extra length of the operating band 13 between the retaining rings 19 and 20 and the stopper ring 21 is relatively long,
The extra length portion is stopped.

When the locking cap 31 is removed from the stopper ring 21, the extra length of the operating band 13 is pulled slightly strongly, so that the locking step 49 is located on one side in the width direction of the locking cap 31. , The locking step 49 is
The distal ring portion 12W is bent so as to be crushed, so that the locking receiving portion is formed.
The engagement between the engagement claw portion 47 and the engagement receiving portion 41A is released, and the engagement cap 31 can be pulled out from the stopper ring 21. Further, in this case, since the locking claw portion 47 is hollow due to the pin extraction hole 52A, the locking step portion 49 can be bent so as to fall down to the pin extraction hole 52A side, which makes it easier to remove. ing. When the locking cap 31 is removed in this manner, the operating band 35 is pulled to the distal end side, and the stop ring 20 moves to the distal end side, and the operating band inserted and engaged with the stop rings 19, 20 is used. 13 is loosened, and the operation band 13 is easily removed from the stop rings 19 and 20.

As described above, in this embodiment, the helmet body 1 has the longitudinal base end attached to one of the left and right side portions thereof and the stop rings 19 and 20 serving as stoppers at the distal end side. In a helmet equipped with a chin band 11 comprising a holding band 12 and an operating band 13 having a longitudinal base end attached to the other of the left and right sides and a distal end side inserted into and engaged with retaining rings 19 and 20, A locking cap 31 is provided to cover the distal end of the holding band 12, and a stopper ring 21 for inserting and locking the locking cap 31 is provided on the distal end side of the outer surface of the holding band 12. Since the locking claw 47 for locking to the locking receiving portion 41A provided on the base end side of 21 is provided, the operating bands are provided on the retaining rings 19 and 20.
13 into the engagement band, and the locking cap 31 provided at the tip of the extra length of the inserted operation band 13 is
By inserting and locking into the stopper 21, the extra length portion does not hang down, and the locking cap 31 at the tip is inserted and locked into the stopper ring 21 along the length direction of the holding band 12. Regardless of the length of the extra length, the locking operation can be easily performed, and the locking cap 31 and the stopper ring 21 can provide a good click feeling when the two are locked. Furthermore, the locking cap 31
As a result, the tip of the operating band 13 is not exposed, so that the appearance and design are improved, and the tip of the operating band 13 is not turned up, so that the durability of the tip of the operating band 13 is also improved.

Further, as described above, in this embodiment, claim 2
In response to this, the holding band 12 is inserted through the stopper rings 19 and 20 and the stopper ring 21 and the inserted distal end is folded back and overlapped, and the holding band 12 at the overlapped portion is sewn. Since the retaining rings 19, 20 and the stopper ring 21 are provided on the holding band 12 by the sewn portion 18 which has been attached, the stopper ring 21 is not attached separately to the retaining band 12, but together with the retaining rings 19, 20. The holding band 12 can be attached by sewing the overlapped portion, and the number of manufacturing steps can be reduced.

Further, in this embodiment, the stopper is constituted by the inner and outer retaining rings 20 and 19, and the distal end side of the holding band 12 is folded back so as to correspond to the third aspect.
W and a sewing portion at the base end of the distal end ring portion 12W.
18 and inner and outer retaining rings 20 and 19 and a stopper ring 21 are provided on the distal ring portion 12W. The stopper ring 21 is composed of an inner frame portion 42 disposed inside the distal ring portion 12W and an outer frame portion disposed outside. 41, and the length of the inner frame portion 42 is
Since the locking cap 31 is formed shorter and the locking receiving portion 41A is provided on the outer frame portion 41, when the locking cap 31 is inserted into the stopper ring 21, the locking claw portion 47 of the locking cap 31 Good click feeling is obtained by locking to the lock receiving portion 41A, and even when gloves are worn, the work of locking the locking cap 31 to the stopper ring 21 can be easily performed. It is also easy to check the locked state. Further, since the inner and outer retaining rings 20 and 19 and the stopper ring 21 are provided by sewing on the distal end ring portion 12W, manufacturing is easy, and the inner frame portion 42 disposed inside the distal end ring portion 12W is further provided. Is formed shorter than the outer frame portion 42, the stopper ring 21 does not tilt even if the inner and outer stopper rings 20, 19 abut against the stopper ring 21 due to a tightening operation or the like. Can be stably performed. In addition, locking cap 31
Of the retaining band 12 is inserted and removed along the distal ring portion 12W of the holding band 12, so that the spring action of the distal ring portion 12W makes it easy to insert and remove the locking cap 12W to and from the stopper ring 21. In addition, since the inner frame portion 42 disposed inside the distal end ring portion 12W is short, the distal end ring portion 12W can be formed small, that is, can be formed to have a small diameter.
This is advantageous for enhancing the spring action of the helmet. Also, conversely,
Since the length of the outer frame portion 41 to which the locking cap 31 is locked is formed longer than that of the inner frame portion 42, the click feeling when the locking cap 31 is locked is improved.

Also, as an effect of the embodiment, since the inclined edge 43A is formed at the distal end side of the side frame portion 43, the stopper ring 21 is arranged close to the base end side of the stop rings 19 and 20. At the same time, the holding bands 12 in the overlapped portion can be sewn to each other by the sewn portion 18 at a position close to the stopper ring 21. Also, the stopper ring 21
Is made of synthetic resin and is formed relatively wide with respect to its length, so that it can be bent and elastically deformed when the locking cap 31 is inserted, making it easy to insert and remove the locking cap 31 Can be. Further, since the locking claw 47 is hollow due to the pin extraction hole 52A, the locking step 49 can bend so as to fall down to the pin extraction hole 52A side, which makes it easier to remove. In addition, since the locking cap 31 is molded from a synthetic resin that is softer and more elastic than the stopper ring 21, it can be inserted without difficulty,
It becomes easy to remove. In addition, since the tip of the locking cap 31 has a convex curved shape and is formed with an inclined guide surface 48, the stopper ring 31 is inserted when the locking cap 31 is inserted.
Even if the position in the width direction is slightly displaced with respect to 21, the convex curved shape makes it possible to insert the stopper ring 21 securely into the stopper ring 21 and to be smoothly guided by the inclined guide surface 48. . Furthermore, since the proximal end step 50 is provided on the proximal end side of the locking cap 31, the locking cap 31 is inserted at the time of insertion.
Does not come out to the base end side of the stopper ring 21,
In addition, since the outer frame portion 41 of the stopper ring 21 fits into the recess 51 of the locking cap 31, it is possible to prevent rattling between the two in the locked state. In addition, connecting bracket
Since the cross-section 17 is formed in a substantially U-shaped cross section, the distal ends of the two bands 12, 13 can be turned inward while being connected to the helmet main body 1, and the turning operation of both bands 12, 13 is easy. become. In addition, a tongue piece is provided on the proximal end side of the chin covers 22 and 32.
Because the tongue piece 30 is provided, the tip 16A of the semi-tuple rivet 16 is not exposed to the inner surface of the helmet body 1 by the tongue piece 30. Further, an insertion hole 26 is formed in the base end side of the chin covers 22 and 32 to insert the turned back base ends 12K and 13K, and the male / female button 27 and the male button 27 are formed in the turned base ends 12K and 13K.
