Description

  The present invention relates to an ear covering device, and more particularly to an ear covering device in which the length of a headband can be easily adjusted.

  It has been known for a long time that an ear covering device has a headband that is curved along the shape of a human head, and a heat retaining cover is attached to a cup member provided at the tip of the headband. It is also well known that the ear covering device is formed so that the length of the headband can be adjusted so that it can be worn according to the size of the head of the user.

Patent Documents 1 and 2 below describe an ear covering device that is formed so that the length of the headband can be adjusted.
Japanese Patent Laid-Open No. 10-79994 JP 2002-11036 A

  The headband (flexible band 18) shown in FIG. 26 of Patent Document 1 has a ring (encapsulated portion 158) at one end of the band main body (semicircular first member 154, semicircular second member 156). 160), and the other end of the band main body is inserted into the ring of the other party and assembled, and the length of the entire headband is adjusted by sliding the band main body in the length direction.

  1 and 2 of Patent Document 2, the ring member (12, 12a) is provided at one end of the band member (11, 11a), and the other end of the band member is connected to the other end. The length of the headband can be adjusted by inserting it into the ring body and sliding the band member, and has the same structure as Patent Document 1.

  The headbands described in Patent Documents 1 and 2 are adjusted so that the headband matches the head of the user before wearing the ear cover. If not, it was necessary to remove the device from the head and readjust the length. In recent years, a headband with a heat insulation cover is also commercialized, but in this case, the adjustment work is done in a groping state because the headband length adjustment work is performed in the heat insulation cover. As a result, there is a problem that it is difficult to obtain a thing that fits the head of one's head with a single adjustment.

  The problem to be solved by the present invention is to provide an ear covering device that is easy to adjust the length of the headband and that fits the head securely in one operation after the device is mounted on its own head. That is.

  The first means for solving the problem is that the ear covering device comprises a band member formed in a band-shaped body and a cup member provided at the free end of the band member. A matching curved shape, in which the cup member is formed in a cross-sectional shape and covers the heat insulating cover, the band member has one main band body and two sub-band bodies, An adjustment guide groove extending in the length direction of the band is provided at the distal end position of the main band body, an engagement protrusion is provided at the base end portion of the sub-band body, and the engagement protrusion is engaged with the adjustment guide groove. The sub-band body is slidably coupled to the main band body, and the length of the band member can be adjusted even after the ear covering device is mounted on a human head. It is a feature.

  A second solving means is the first solving means, wherein the main band body of the band member is provided with a thin portion in which the thickness in the vicinity of the top of the band body is formed slightly thinner than the other portions. On the other hand, a spring effect is exerted to bias the cup member provided at the tip toward the center of the apparatus.

  Since the length of the band member can be adjusted even after the ear covering device is mounted on the human head, the length of the band member can be adjusted as compared with the conventional structure. It is extremely easy and has the effect of being easy to use.

  Since the band member exhibits the spring effect of pressing the cup member against a human ear, the band member has an effect of being superior in fit compared to the conventional structure.

  In FIG. 1, the ear covering device 1 includes a band member 10 formed in a band-shaped body and a cup member 20 provided at a tip which is a free end of the band member 10, and the band member 10 has an arch shape. The cup member 20 is formed in a curved shape that matches the shape of the human head, and the cup member 20 is covered with a cloth heat insulating cover 30.

  In the embodiment, the band member 10 and the cup member 20 are both plastic molded products. In the embodiment, the cup member 20 is covered with the heat insulating cover 30, but the band member 10 can be covered with the heat insulating cover.

  2 to 6, the band member 10 is composed of one main band body 101 and two sub band bodies 102, and the sub band body 102 is disposed at a distal end position serving as a free end of the main band body 101. Are slidably coupled to each other, and the overall length of the band member 10 can be adjusted by appropriately selecting the sliding position of the sub-band body 102 (FIGS. 2 and 3).

  The main band body 101 is formed with an adjustment guide groove 110 extending in the length direction of the band at both tip positions, and the adjustment guide groove 110 reaches the vicinity of the edge of the main band body 101. . In addition, the adjustment guide groove 110 is disposed on the front side of the main band body 101 and in the center so that the shape of the sky surface that crosses the portion where the adjustment guide groove 110 is formed exhibits the “E” shape of Katakana. The formed surface adjustment recess 111 is formed (FIG. 4), and the back surface adjustment recess 112 having the adjustment guide groove 110 disposed in the center is formed on the back surface side of the main band body 101 (FIG. 5). The cross-sectional shape of the groove 110 is stepped.

  The back surface adjustment recess 112 extends to the end edge of the main band body 101 beyond the adjustment guide groove 110.

  An engagement protrusion 120 is provided on the surface of the base end portion of the sub-band body 102. The engagement protrusion 120 has a protruding head 121 having a diameter larger than that of the shaft portion at the top, and the engagement protrusion 120 The protrusion 120 is engaged with the adjustment guide groove 110 of the main band body 101 so that the main band body 101 and the sub band body 102 are slidably coupled. The band base end portion 102a of the sub-band body 102 is to be polymerized with the back side of the main band body 101 at the position where the adjustment guide groove 110 of the main band body 101 is formed. The width dimension is made to coincide with the width of the back surface adjustment recess 112 of the main band body 101.

  When the engagement protrusion 120 of the sub-band body 102 is engaged with the adjustment guide groove 110 of the main band body 101, the protruding head 121 is on the surface adjustment recess 111 of the adjustment guide groove 110 on the surface side of the engagement protrusion 120. In addition, since the sub-band body 102 is engaged with the back surface adjustment recess 112 on the back surface side, the main band body 101 and the sub-band body 102 are free to slide in the length direction. However, the engagement state of both is maintained (FIG. 6).

  The overhanging head 121 formed on the engagement protrusion 120 is formed to have a larger diameter than the shaft portion of the protrusion, and the width of the adjustment guide groove 110 is substantially the same as the shaft portion of the engagement protrusion 120. Since these members are plastic molded products, if the protruding head 121 of the engagement protrusion 120 is press-fitted into the adjustment guide groove 110, the adjustment guide groove 110 is slightly expanded to engage the engagement protrusion. 120 can be allowed to enter, and both can be engaged.

  Since the engagement protrusion 120 slidably couples the main band body 101 and the sub-band body 102, the overhanging head 121 is not limited to the embodiment, but a flange for maintaining the engagement state of both. It is sufficient that the cross-sectional shape is slightly larger than the width of the adjustment guide groove 110.

  In the embodiment, when the main band body 101 and the sub-band body 102 are coupled, the engagement protrusion 120 is pushed into the adjustment guide groove 110 from the back surface adjustment recess 112 of the main band body 101. Since the band member 10 is made of plastic, the protruding head 121 of the engaging protrusion 120 is formed to be slightly larger than the adjustment guide groove 110. However, when the engaging protrusion 120 is pushed firmly into the adjustment guide groove 110, the protrusion The head 121 pushes the adjustment guide groove 110 and is mounted in the groove, and thereafter, the engaged state is maintained and engaged without dropping.

  When the engaging protrusion 120 of the sub-band body 102 is mounted in the adjustment guide groove 110 of the main band body 101, both are slidably coupled to form the band member 10, so that the sub-band body 102 is attached to the band. The entire length of the band member 10 can be adjusted by selecting the sliding position of the sub-band body 102 to an appropriate position.

  In order to fit the cup member 20 covered with the heat insulating cover 30 to a human ear, the main band body 101 forms a thin portion 101a in which the thickness in the vicinity of the top of the band body is slightly thinner than other portions. ing. Incidentally, the thickest part of the main band body 101 was 4.0 mm, and the thinnest part was 3.2 mm.

  The thin portion 101a formed in the vicinity of the top portion of the main band body 101 exhibits a spring effect that urges the end portions (cup members 20) of the band member 10 toward the inside of the apparatus. At the same time, each sub-band body 102 is formed with a bent portion 102b that is bent at a gentle angle. Again, the bent portion 102b has a spring effect that urges the tip portions toward each other. It is something that demonstrates. Incidentally, in the front view of the band member 10, the bent portion 102 b of the sub-band body 102 disposed on the left side exhibits a “K” character of Hiragana.

  7 and 8, the cup member 20 has a cup shape in cross section, and a first band insertion for inserting the sub-band body 102 into the cup inside the rising portion which becomes the side wall of the cup. An opening 201 is formed, and a second band insertion opening 202 and a third band insertion opening 203 corresponding to the first band insertion opening 201 are provided in parallel at the bottom of the cup. The second and third band insertion ports 202 and 203 are for fixing the sub-band body 102 to the cup bottom, and at least the second band insertion port 202 has a sub-band shape in the mouth shape. The size is substantially the same as the cross-sectional shape of 102.

  In the figure, 130 is a stopper claw piece provided on the sub-band body 102, and the sub-band body 102 is inserted into the cup member 20 from the first band insertion port 201 toward the third band insertion port 203. Then, when the stopper claw piece 130 gets over the second band insertion port 202, the stopper claw piece 130 engages with the second band insertion port 202, and the cup member 20 and the sub-band body 102 are coupled.

  Further, the cup member 20 is provided with a heat insulating cover insertion port 210 for inserting the heat insulating cover 30 into the cup adjacent to the first band insertion port 201.

  The heat insulation cover 30 is formed of a fabric having a high heat insulation effect, and is previously sewn into a bag shape having one end opened. Here, the heat insulation cover 30 covers the cup member 20, and then inserts the opening portion into the cup member 20 from the heat insulation cover insertion opening 210. The sub-band body 102 is inserted after the cup member 20 is covered with the heat insulating cover 30, and therefore, the heat insulating cover 30 is provided with an insertion cut (details are omitted) for inserting the sub-band body 102. .

  Since the present invention is configured as described above, in order to assemble the ear covering device 1, the sub-band body 102 is joined to the bent inner side of the main band body 101, and the sub-band body 102 is engaged with the adjustment guide groove 110. The projection 120 is pushed in, and the engagement projection 120 is slidably engaged with the adjustment guide groove 110 to couple the main band body 101 and the sub-band body 102 to form the band member 10. Since the sub-band body 102 is accommodated in the back surface adjustment recess 112 formed on the back surface of the main band body 101, no step is generated between the bent inner surface of the main band body 101 and the sub-band body 102. The band member 10 directly covering the head of the head can be worn without a sense of incongruity.

  Since the adjustment guide groove 110 that engages the engagement protrusion 120 of the sub-band body 102 is formed in the surface adjustment recess 111, when the engagement protrusion 120 is engaged in the surface adjustment recess 111, the overhang is formed. The head 121 does not protrude from the main band body 101, and the band surface is formed flat and has a good appearance.

  Next, the sub-band body 102 is inserted from the first band insertion port 201 to the third band insertion port 203 of the cup member 20 already covered with the heat insulating cover 30. Since the heat insulation cover 30 is provided with a cut for inserting the sub-band body 102 in advance, the sub-band body 102 is guided from the cut into the cup. Here, when the tip of the sub-band body 102 passes through the second band insertion port 202, the stopper claw piece 130 of the sub-band body 102 engages with the second band insertion port 202, and both are coupled to each other. The secondary band body 102 and the cup member 20 are joined together by force, thereby forming an ear covering device.

  The ear covering device 1 is worn from the top of the head, and the cup member 20 abuts a flat surface on the inner side against the human ear. At this time, if the cup member 20 is not properly in contact with the ear portion, the entire length of the band member 10 is adjusted by sliding the sub-band body 102 with respect to the main band 101. Since the main band 101 and the sub-band body 102 are slidably coupled to the adjustment guide groove 110 provided in the main band 101, the sub-band 102 is joined to the main band body 101. The entire length of the band member 10 can be adjusted only by sliding along.

  In the present invention, the length of the band member 10 can be adjusted even after the ear covering device 1 is mounted on the head of a person. Is very easy and easy to use.

  Further, in the present invention, since the vicinity of the top of the main band body 101 is formed in the thin portion 101a, the band member 10 is made to exhibit a spring effect of pressing the cup member 20 against the ear portion, and has an excellent fit. Is.
