[Industrial applications]

 The present invention relates to a cold-ear earpiece, and more particularly to a cold-ear earpiece used by being mounted on a helmet.

[0002]

[Prior art and its problems]

 Heretofore, as this kind of earpiece, Japanese Utility Model Publication No. 59-29926, Japanese Utility Model Publication No. 60-9209, Japanese Utility Model Publication No. 60-9210, Japanese Utility Model Publication No. 3-52498, and Japanese Utility Model Publication No. 3-52499. As can be seen in many examples in Japanese patent publications and the like, it is well known that an inverted U-shaped headband is provided with earbrush main bodies fitted with brushed heat insulating sheets on both ends thereof.

However, in the above-described earbuds with a headband, when a helmet has to be worn when working outdoors or traveling on a bicycle or a motorbike, the earbuds are placed under the helmet. When worn, there are some drawbacks such as the headband getting in the way and pressing on the head locally, or the chin strap for wearing the helmet strongly presses the body of the ear covering against the ear side, which significantly impairs the feeling of wearing. there were.

[0004] Therefore, an earpiece that is supposed to be used by being mounted on a helmet is being proposed, but a conventional product of this type is found in, for example, Japanese Utility Model Publication No. 62-44968. As shown in the figure, a stay or arm member is attached to the outer periphery of the helmet, and the ear covering body is attached to this. Such conventional proposals are generally cumbersome to attach and detach to and from the helmet, and do not have the convenience of being easily attached to the helmet as needed for outdoor work, etc. Since the cover body is attached, it shifts in conjunction with the movement of the helmet, it does not necessarily feel good to wear, and the presence of the ear cover body is an obstacle when attaching and detaching the helmet and storing it. There was a point. This invention is based on the background of the prior art as described above, and that the helmet is always equipped with a chin strap for wearing the helmet, and it is located near the wearer's ear when the helmet is worn. In view of the above, it is an object of the present invention to provide a cold protection earpiece for a helmet in which the main body of the ear covering is detachably attached to the chin strap and can be used.

【Example】

 Next, one of preferred embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, an earpiece according to the present invention is a pair of left and right ear covers used by being attached to a pair of left and right chin straps (21) (21) for wearing a helmet (20). It consists of the body (1) and (1).

As shown in FIG. 2, the earmuff body (1) includes a disc-shaped base body (2) made of a hard synthetic resin, an annular holding frame (3) also made of a synthetic resin, and a raised heat insulating sheet (4). , And a cup-shaped cap body (5). The nap raising heat insulation sheet (4) is wound around the annular holding frame (3) from the outside to the inside so that the inside of the holding frame (3) has an annular peripheral edge (6). ) Is tightly fitted to the base body (2) so as to cover and cover the inner side surface of the base body (2). As shown in FIG. 4, the holding frame (3) and the base body (2) have inwardly convex edges (inward protrusions) at their respective fitting portions so that the joined state after the fitting can be firmly held. 7) and an outer convex edge (8) are provided, and both convex edges can be engaged with each other via the heat insulating sheet (4).

On the other hand, the disk-shaped substrate (2) has a pair of bulges (9) (9) on the left and right on the outer surface side thereof. These bulges (9) and (9) have a string-conducting space (10) in which the upper part of the bulge part has an upwardly expanding shape and the lower part of the bulge part has a straight groove shape. is doing. Therefore, the chin strap (21) of the helmet (20) has a Y-shaped entanglement between the upper V-shaped hanging cord portion (21a) and the lower connecting cord portion (21b) connected thereto. The part can be accommodated in the space (10) for string conduction without any trouble. The cap body (5) has a bowl-like shape in which the inner surface side is opened and bulges outward, and the cap body (5) is formed on the outer surface of the disk-shaped base body (2) on the pair of bulged portions (9) and (9). It is designed so that it can be detachably attached. In order to prevent the cap body (5) from coming off in this mounted state, an annular groove (11) is provided on the inner peripheral surface of the end portion of the cap body (5) as shown in FIG. (9) A ridge (12) is provided on the outer surface of (9), and the engagement of these ridges (12) makes it possible to keep the bonded state of the base body (2) and the cap body (5) stable. . However, this coupled state can be dissociated by strongly pulling the cap body (5) in the separating direction, and therefore, the cap body (5) can be attached and detached. (13) is a positioning protrusion provided on the bulge (9), (14) is a fitting hole corresponding to this, and (15) and (16) are ventilation holes. , (17) are finger-hooking projections for removal provided on the periphery of the cap body (5), and (18) is a through hole provided on the bottom side of the string conducting space (10).

In the state where the cap body (5) is fitted and mounted on the base body (2) as described above, a gap between the peripheral edge of the cap body (5) and the peripheral edge portion of the base body (2) is As shown in FIG. 5, a slit-shaped string-conducting gap (19) communicating with the upper and lower ends of the string-conducting space (10) is formed.

When the earpiece is used, the cap body (5) is detached from the base body (2) and the space (10) for string conduction of the base body (2) is attached to the helmet ( Position the Y-shaped entangled portion of the chin strap (21) of 20) in the fitted state, and then fit the cap body (5) to both bulged portions (9) (9) of the base body (2) and outside thereof. Fit in. As a result, the earmuff body (1) (1) is mounted with the chin strap (21) inserted between the base body (2) and the cap body (5). In this mounted state, the earmuff body (1) (1) is slidable in the vertical direction with respect to the chin strap (21), but it is between the heat insulating sheet (4) and the peripheral edge of the cap body (5). Since the string (21) is sandwiched between the two and causes frictional resistance, the string (21) cannot be freely displaced along the string (21).

Therefore, by mounting the helmet (20) on the head in this mounted state, the ear covering main body (1) (1) holds both ears of the user to the inside of the raised heat insulating sheet (4) side. Can be covered.

The above embodiments are merely examples of the preferred specific designs of the present invention. The main body (1) (1) of the earmuff need only have a means for attaching to and detaching from the chin strap (21) of the helmet (20), and the attaching means is shown in the embodiment. Any design changes other than the structure are allowed. For example, a band member for attachment may be attached to the outer surface of the cap body (5), and the band member may be attached to the chin strap (21), or the chin strap (both fasteners, stop buttons, etc. may be attached. 21) The ear covers may be detachably attached to the body.

[0016]

[Effect of device]

 Since the earpiece according to the present invention is such that the ear-cover main body is detachably attached to the chin strap for wearing the helmet as described above, it does not hinder the wearing of the helmet. It is possible to protect the ears from the cold without using them, and it is structurally simple and can be manufactured and provided at a low price as compared with the case where the ear covers are separately attached to the main body of the helmet via an arm member or the like. Moreover, since the ear covering body is attached to the chin strap of the helmet, it can be fitted stably along the ear part when the helmet is worn, and it does not move unintentionally with the helmet. There is no danger of pressing the part strongly, and it is excellent in wearing and use feeling.

Further, when the chin strap can be mounted by being conducted between the base body of the ear covering main body and the cap body mounted on the outer side thereof, the chin strap may be attached. Even when tightened firmly, the ear covering body is not strongly pressed to the ear side with the cord, and it is possible to make the user feel comfortable to wear.

Further, as described in claim 3, by forming a string-conducting space having an expanded shape in the upper part on the base body side, a V-shaped hanging string on the upper part of the helmet wearing jaw string is formed. The ear covering main body can be stably and conveniently attached to the Y-shaped portion connected to the lower connecting cord portion.
