Description

この発明は、遊泳や競泳等で使用するのに好適な水中眼鏡に関する。   The present invention relates to underwater glasses suitable for use in swimming, swimming, and the like.

従来、一対のレンズ部の内端部どうしを鼻ベルト部でつなぎ、外端部どうしをヘッドバンド部でつなぎ、バックルによってそのヘッドバンド部が長さ調節可能な水中眼鏡は周知である。例えば、特開２００２−４５４３９号公報（特許文献１）に開示された水中眼鏡は、一対のレンズ部それぞれの外端部にバックルとして機能するヘッドバンド部掛回部と突起部とを有する。水中眼鏡着用者の頭部の後方から頭部前方へ向かって延びたヘッドバンド部は、掛回部に掛け回されて折り返された後に、ヘッドバンド部の長さ方向へ間欠的に形成されている透孔にバックルの突起部が挿入されることによって所要の長さに調整される。
特開２００２−４５４３９号公報 2. Description of the Related Art Conventionally, underwater glasses are known in which the inner end portions of a pair of lens portions are connected by a nose belt portion, the outer end portions are connected by a headband portion, and the length of the headband portion can be adjusted by a buckle. For example, underwater eyeglasses disclosed in Japanese Patent Application Laid-Open No. 2002-45439 (Patent Document 1) have a headband portion hanging portion and a projection portion that function as a buckle at each outer end portion of a pair of lens portions. The headband portion extending from the back of the head of the wearer of the underwater glasses toward the front of the head is intermittently formed in the length direction of the headband portion after being turned around and folded back by the hanging portion. The required length is adjusted by inserting the protrusion of the buckle into the through hole.
JP 2002-45439 A

特許文献１に記載された水中眼鏡は、ヘッドバンド部に形成された透孔に対してバックルの突起が挿抜されるだけでヘッドバンド部の長さを調整することができるという調整作業の簡便さを有する反面、突起が確実に挿入されなければ、ヘッドバンド部がレンズ部材の外端部から外れてしまうという可能性がある。また、水中眼鏡を着用したときにヘッドバンド部に作用する張力は、突起が挿入されている透孔の周縁部分に集中するから、水中眼鏡を繰り返し使用しているとその周縁部分が傷み易いという場合がある。   The underwater eyeglasses described in Patent Document 1 can be easily adjusted by simply adjusting the length of the headband part simply by inserting and removing the projection of the buckle into the through hole formed in the headband part. On the other hand, if the protrusion is not securely inserted, the headband portion may come off from the outer end portion of the lens member. In addition, when the underwater glasses are worn, the tension acting on the headband portion is concentrated on the peripheral portion of the through hole into which the protrusion is inserted. Therefore, if the underwater glasses are repeatedly used, the peripheral portion is easily damaged. There is a case.

この発明は、特許文献１に記載されている如き水中眼鏡において、レンズ部の外端部で頭部の後方へ向かうように折り返されたヘッドバンド部がその外端部から簡単に外れることがないように改良を施すこと、およびヘッドバンド部に形成された透孔の周縁部分が傷むことがないように改良を施すことを課題にしている。   According to the present invention, in the underwater glasses as described in Patent Document 1, the headband portion that is folded back toward the rear of the head at the outer end portion of the lens portion is not easily detached from the outer end portion. It is an object of the present invention to make improvements and to make improvements so that the peripheral portion of the through hole formed in the headband portion is not damaged.

課題を解決するための手段および発明の効果Means for Solving the Problems and Effects of the Invention

前記課題を解決するために、この発明が対象とするのは、一対のレンズ部と、鼻ベルト部と、ヘッドバンド部とを有し、前記鼻ベルト部によって前記レンズ部の内端部分どうしがつながり、前記ヘッドバンド部によって前記レンズ部の外端部分どうしが前記ヘッドバンド部の長さを調節可能につながる水中眼鏡である。   In order to solve the above problems, the present invention is directed to a pair of lens portions, a nose belt portion, and a headband portion, and the inner end portions of the lens portions are separated by the nose belt portion. Underwater glasses that are connected to each other so that the outer end portions of the lens unit can be adjusted in length by the headband unit.

かかる水中眼鏡において、この発明が特徴とするところは、次のとおりである。
前記ヘッドバンド部は、水中眼鏡着用者の頭部に掛回された状態において、前記頭部の後方から前記頭部の前方へ向かって延びる両端部を有する。これら両端部のそれぞれは、複数のバンド挿通孔を有するバックルの前記挿通孔のいずれかに通されて前記レンズ部の外端部分にまで延びるとともに、前記外端部分では前記頭部の前方から前記頭部の後方へ向かうように折り返されて前記バックルにまで延びる折り返し部分を形成している。前記折り返し部分は、前記挿通孔のいずれかに通されて前記折り返し部分の長さ方向に間欠的に形成されている複数の透孔のいずれかに対して前記バックルに形成された突起部が抜脱可能に挿入され、かつ前記突起部よりも前記頭部の前方寄りにおいて前記ヘッドバンド部の前記頭部の前方へ向かって延びる部分と重なり合っている。 In such underwater eyeglasses, the present invention is characterized as follows.
The headband portion has both end portions that extend from the rear of the head toward the front of the head in a state of being hung on the head of the underwater spectacles wearer. Each of these both end portions is passed through one of the insertion holes of the buckle having a plurality of band insertion holes and extends to the outer end portion of the lens portion, and at the outer end portion, from the front of the head. A folded portion that is folded back toward the back of the head and extends to the buckle is formed. The folded portion has a protrusion formed on the buckle with respect to any of a plurality of through holes that are intermittently formed in the length direction of the folded portion by passing through any of the insertion holes. It is removably inserted and overlaps with a portion of the headband portion extending toward the front of the head nearer to the front of the head than the protrusion.

この発明に係る水中眼鏡では、ヘッドバンド部の端部のうちで折り返されて頭部の前方から頭部の後方へ向かう折り返し部分が、その部分に形成された透孔にバックルの突起部を挿入されるとともに、突起部よりも頭部の前方寄りにおいてヘッドバンド部の端部のうちで頭部の前方へ向かう部分と重なり合っているから、水中眼鏡を着用したときにヘッドバンド部にかかる張力が、透孔に挿入された突起部に支えられるのみならず、ヘッドバンド部の互いに重なり合う部分においても支えられる。このような水中眼鏡では、それを着用したときにヘッドバンド部の透孔に対する突起部の挿入が不完全な場合であっても、ヘッドバンド部がレンズ部の外端部から簡単には外れない。   In the underwater glasses according to the present invention, the folded portion of the headband portion that is folded back from the front of the head toward the rear of the head inserts the protrusion of the buckle into the through hole formed in the portion. In addition, since it overlaps with the portion of the end of the headband portion that is closer to the front of the head than the protrusion, the portion that goes to the front of the head, the tension applied to the headband when wearing underwater glasses In addition to being supported by the protrusions inserted into the through holes, the headband portions are also supported at the overlapping portions. In such underwater glasses, the headband part cannot be easily detached from the outer end part of the lens part even when the projection part is not completely inserted into the through hole of the headband part when wearing it. .

この発明の好ましい実施態様の一つにおいて、前記ヘッドバンド部の両端部それぞれは、前記ヘッドバンド部の幅方向へ延びるとともに前記ヘッドバンド部の長さ方向に間欠的に形成されている肉厚部を有し、前記透孔のそれぞれが前記肉厚部のそれぞれに形成されている。   In one of the preferred embodiments of the present invention, each of both end portions of the headband portion extends in the width direction of the headband portion and is thickly formed intermittently in the length direction of the headband portion. Each of the through holes is formed in each of the thick portions.

この発明に係る水中眼鏡では、ヘッドバンド部が透孔の近傍に肉厚部を有するから、透孔に突起部が挿入されたヘッドバンド部に張力が作用しても、透孔の周縁部は傷み難い。   In the underwater glasses according to the present invention, since the headband portion has a thick portion in the vicinity of the through hole, even if tension acts on the headband portion in which the projection portion is inserted into the through hole, the peripheral portion of the through hole is Hard to hurt.

この発明の好ましい実施態様の他の一つにおいて、前記両端部のそれぞれは、前記頭部の前方へ向かって延びる部分が前記バックルの前記挿通孔に通されるときに前記ヘッドバンド部の長さ方向において屈曲した状態にあり、前記折り返し部分は、前記肉厚部が前記屈曲した状態にある部分に前記頭部の後方から前記頭部の前方へ向かう方向において当接している。   In another preferred embodiment of the present invention, each of the both end portions has a length of the headband portion when a portion extending forward of the head is passed through the insertion hole of the buckle. The folded portion is in contact with the portion where the thick portion is bent in the direction from the rear of the head toward the front of the head.

この発明に係る水中眼鏡では、ヘッドバンド部の端部のうちの折り返し部分に形成されている肉厚部が端部のうちの屈曲した状態にある部分に頭部の後方から当接しているから、水中眼鏡を着用してヘッドバンド部に張力が作用すると、その張力は、互いに当接する肉厚部と屈曲した状態にある部分とに支えられ、突起部が挿入されている透孔の周縁部分には及び難い。それゆえ、この水中眼鏡では、着用を繰り返しても、ヘッドバンド部における透孔の周縁部分は傷むことがない。   In the underwater glasses according to the present invention, the thick portion formed at the folded portion of the end portion of the headband portion is in contact with the bent portion of the end portion from the back of the head. When underwater glasses are worn and tension is applied to the headband part, the tension is supported by the thick part abutting on each other and the bent part, and the peripheral part of the through hole into which the protrusion is inserted It is difficult to reach. Therefore, in the underwater glasses, the peripheral portion of the through hole in the headband portion is not damaged even if the wear is repeated.

添付の図面を参照して、この発明に係る水中眼鏡の詳細を説明すると、以下のとおりである。   The details of the underwater glasses according to the present invention will be described below with reference to the accompanying drawings.

図１に斜視図で示された水中眼鏡１は、一対のレンズ部２と、鼻ベルト部３と、ヘッドバンド部４とを有する。レンズ部２は、ポリカーボネート樹脂やアクリル樹脂等の硬質樹脂で形成されたレンズ６と、レンズ６と一体に形成されたフレーム７と、水中眼鏡着用者の顔面に密着させるシリコン樹脂やウレタン樹脂、天然ゴム等の軟質弾性材料で形成されたパッド８とを有する。フレーム７は、水中眼鏡着用者の鼻部（図示せず）寄りに位置する内端部１１と、耳部（図示せず）寄りに位置する外端部１２とを有する。鼻ベルト部３は、レンズ部２それぞれの内端部１１に好ましくは着脱可能な状態にあって、レンズ部２の内端部１１どうしをつないでいる。ヘッドバンド部４は、水中眼鏡着用者の頭部に掛け回されるもので、着用状態において、頭部の後方に当接するバンド中央部１６と、頭部の後方から頭部の前方へ延びる両バンド端部１７と、バンド端部１７のそれぞれに取り付けられているバックル１８とを有する。端部１７は、レンズ部２の外端部１２に形成されているベルト通し１９に通されて頭部の後方へ向かって延びる折り返し部分２１を有する。折り返し部分２１では、ヘッドバンド部４の長さを調節するための複数の透孔２２がヘッドバンド部４の長さ方向に間欠的に並んでいる。バックル１８は、ポリカーボネート樹脂やアクリル樹脂、ＡＢＳ樹脂等の硬質プラスチックで形成されており、ヘッドバンド部４の透孔２２に挿抜可能な突起部２３を有する。   The underwater glasses 1 shown in a perspective view in FIG. 1 have a pair of lens parts 2, a nose belt part 3, and a headband part 4. The lens unit 2 includes a lens 6 formed of a hard resin such as polycarbonate resin or acrylic resin, a frame 7 formed integrally with the lens 6, a silicon resin or urethane resin that is in close contact with the face of the underwater glasses wearer, natural And a pad 8 made of a soft elastic material such as rubber. The frame 7 has an inner end portion 11 located near the nose portion (not shown) of the underwater glasses wearer and an outer end portion 12 located closer to the ear portion (not shown). The nose belt portion 3 is preferably detachably attached to the inner end portion 11 of each lens portion 2 and connects the inner end portions 11 of the lens portion 2 to each other. The headband portion 4 is hung around the head of the underwater eyeglass wearer, and in a worn state, the headband portion 4 is in contact with the back of the head, and both the headband portion 4 extends from the back of the head to the front of the head. It has a band end 17 and a buckle 18 attached to each of the band end 17. The end portion 17 has a folded portion 21 that passes through a belt loop 19 formed in the outer end portion 12 of the lens portion 2 and extends toward the rear of the head. In the folded portion 21, a plurality of through holes 22 for adjusting the length of the headband portion 4 are arranged intermittently in the length direction of the headband portion 4. The buckle 18 is made of a hard plastic such as polycarbonate resin, acrylic resin, or ABS resin, and has a protrusion 23 that can be inserted into and removed from the through hole 22 of the headband portion 4.

図２，３は、図１のＩＩ−ＩＩ線矢視図とバックル１８の斜視図とであって、図２では、水中眼鏡１の一部分が断面図で示されている。水中眼鏡１は、レンズ部２とパッド８とが一体的に成形されており、パッド８はレンズ部２から外れることがない。ヘッドバンド部４におけるバックル１８では、第１枠部３１と第２枠部３２との間が第１仕切り部３３と第２仕切り部３４とで仕切られることによって、バンド端部１７が挿通される第１、第２、第３バンド挿通孔２６，２７，２８が水中眼鏡着用者の頭部後方から前方へ順に並ぶように形成されている。図３において上下方向へ延びる第１枠部３１、第２枠部３２、第１仕切り部３３、第２仕切り部３４のそれぞれは、ヘッドバンド部４の長さ方向へ互いに平行して延びる第３枠部３５ａと第４枠部３５ｂとにつながっている。第１枠部３１には突起部２３が形成されており、その突起部２３は、長円形の頂部３６（図１参照）と円柱状の軸部３７とを有し、軸部３７は長さＬを有する。図２において、ヘッドバンド部４の端部１７は、頭部の前方へ向かって延びる部分がバックル１８の内側にあり、幅の広い第１挿通孔２６と幅の狭い第２挿通孔２７とに通された後に、レンズ部２の外端部１２において折り返されている。端部１７のうちの折り返し部分２１は、バックル１８の内側から第１挿通孔２６とほぼ同じ幅を有する第３挿通孔２８に通され、さらに後方へ延びる部分では複数の透孔２２のうちの一つに対して突起部２３が挿入されている。突起部２３は、水中眼鏡１が着用されるときに、ヘッドバンド部４を所要の長さに維持すると同時に、折り返し部分２１の揺れ動きを抑えるストッパーとして機能するもので、第１枠部分３１から折り返し部分２１と交差するように延びている。   2 and 3 are a sectional view taken along the line II-II in FIG. 1 and a perspective view of the buckle 18. In FIG. 2, a part of the underwater glasses 1 is shown in a sectional view. In the underwater glasses 1, the lens unit 2 and the pad 8 are integrally formed, and the pad 8 does not come off the lens unit 2. In the buckle 18 in the headband part 4, the band end part 17 is inserted by partitioning the first frame part 31 and the second frame part 32 by the first partition part 33 and the second partition part 34. The first, second, and third band insertion holes 26, 27, and 28 are formed in order from the rear of the head of the underwater glasses wearer to the front. In FIG. 3, each of the first frame portion 31, the second frame portion 32, the first partition portion 33, and the second partition portion 34 extending in the vertical direction extends in parallel with each other in the length direction of the headband portion 4. It is connected to the frame part 35a and the fourth frame part 35b. The first frame portion 31 is formed with a protrusion 23, and the protrusion 23 has an oval top portion 36 (see FIG. 1) and a cylindrical shaft portion 37, and the shaft portion 37 has a length. L. In FIG. 2, the end portion 17 of the headband portion 4 has a portion extending toward the front of the head inside the buckle 18, and has a wide first insertion hole 26 and a narrow second insertion hole 27. After passing, it is folded back at the outer end 12 of the lens unit 2. The folded portion 21 of the end portion 17 is passed from the inner side of the buckle 18 to a third insertion hole 28 having substantially the same width as the first insertion hole 26, and in a portion extending further rearward, of the plurality of through holes 22. One protrusion 23 is inserted into one. The projecting portion 23 functions as a stopper that keeps the headband portion 4 at a required length when the underwater eyeglasses 1 are worn, and at the same time suppresses the swinging motion of the folded portion 21, and is folded back from the first frame portion 31. It extends so as to intersect the portion 21.

図４は、ヘッドバンド部４における端部１７の斜視図である。端部１７は、外面１７ａと、内面１７ｂと、端面１７ｃとを有し、外面１７ａには肉厚部４１によって凹凸が形成され、内面１７ｂは平滑に形成されている。肉厚部４１は、端部１７の幅全体にわたって延びており、端面１７ｃに現われた形状は幅Ｗを有する台形ないし弧を画いている。肉厚部４１のそれぞれには、外面１７ａと内面１７ｂとの間を貫通する透孔２２が形成されており、かような肉厚部４１は、端部１７における透孔２２の周縁部分の強度向上に寄与している。また、好ましい肉厚部４１は、その厚さＴが突起部２３の軸部３７の長さＬとほぼ同じであるうえに、透孔２２の径が軸部３７の径とほぼ同じであって、透孔２２に突起部２３が挿入されると、図２に示されているように突起部２３の頂部３６と軸部３７とに密着する。さらに図２に示されているように、突起部２３の近傍において、ヘッドバンド部４の端部１７が頭部の前方へ向かって第１挿通孔２６から第２挿通孔２７へと延びる部分４２に対して肉厚部４１のうちの肉厚部４１ａが頭部の後方から当接している。かようなヘッドバンド部４では、水中眼鏡１が着用されて、折り返し部分２１に矢印Ａ（図２参照）で示す頭部前方へ向かう方向の張力が作用すると、その張力は、折り返し部分２１の幅全体に延びる肉厚部４１が端部１７の部分４２と当接するところで支えられる。したがって、張力は、突起部２３が挿入されている透孔２２の周縁部分に集中するということがなく、その周縁部分は傷むことがない。折り返し部分２１は透孔２２の周囲で損傷を受けることがない。また、その張力は、肉厚部４１が形成されている折り返し部分２１の幅全体で支えられるから、折り返し部分２１は、その幅全体がほぼ一様に伸長して、透孔２２の近傍だけが著しく伸長するということがない。但し、この発明は、このように作用する肉厚部４１を持たず厚さが一様で平坦なヘッドバンド部４を使用して実施することも可能であって、そのような水中眼鏡１は、図１の水中眼鏡１ほどに顕著ではないが、第１仕切り部３３の近傍で平坦な端部１７どうしが重なり合って水中眼鏡１の着用時に生じる張力を支え、突起部２３が挿入されている透孔２２の周縁部分に張力が集中することを避けることができる。   FIG. 4 is a perspective view of the end portion 17 in the headband portion 4. The end portion 17 has an outer surface 17a, an inner surface 17b, and an end surface 17c. The outer surface 17a is unevenly formed by the thick portion 41, and the inner surface 17b is formed smoothly. The thick portion 41 extends over the entire width of the end portion 17, and the shape appearing on the end face 17 c defines a trapezoid or arc having a width W. Each of the thick portions 41 is formed with a through hole 22 penetrating between the outer surface 17a and the inner surface 17b. The thick portion 41 has a strength of the peripheral portion of the through hole 22 at the end portion 17. Contributes to improvement. Further, the preferable thick portion 41 has a thickness T that is substantially the same as the length L of the shaft portion 37 of the projection 23, and the diameter of the through hole 22 is substantially the same as the diameter of the shaft portion 37. When the protruding portion 23 is inserted into the through hole 22, the protruding portion 23 comes into close contact with the top portion 36 and the shaft portion 37 of the protruding portion 23 as shown in FIG. 2. Further, as shown in FIG. 2, in the vicinity of the projection 23, the end 42 of the headband portion 4 extends from the first insertion hole 26 to the second insertion hole 27 toward the front of the head. On the other hand, the thick part 41a of the thick part 41 is in contact with the back of the head. In such a headband part 4, when the underwater glasses 1 are worn and a tension in the direction toward the front of the head indicated by the arrow A (see FIG. 2) acts on the folded part 21, the tension is applied to the folded part 21. A thick portion 41 extending across the entire width is supported where it abuts against the portion 42 of the end portion 17. Therefore, the tension does not concentrate on the peripheral portion of the through hole 22 in which the protrusion 23 is inserted, and the peripheral portion is not damaged. The folded portion 21 is not damaged around the through hole 22. Further, since the tension is supported by the entire width of the folded portion 21 in which the thick portion 41 is formed, the folded portion 21 extends substantially uniformly in the entire width so that only the vicinity of the through hole 22 is present. There is no significant elongation. However, the present invention can also be carried out using the headband portion 4 having a uniform and flat thickness without the thick portion 41 acting as described above. Although not as remarkable as the underwater glasses 1 in FIG. 1, the flat end portions 17 overlap each other in the vicinity of the first partition portion 33 to support the tension generated when the underwater glasses 1 are worn, and the protrusions 23 are inserted. Concentration of tension on the peripheral edge portion of the through hole 22 can be avoided.

図５は、この発明に係る水中眼鏡１に使用可能なバックル１８の一態様を示す図３と同様な図である。このバックル１８では、突起部２３が第２仕切り部３４に形成されている。このバックル１８を使用した水中眼鏡１では、図２に示されているように、ヘッドバンド部４の端部１７が第１、第２、第３挿通孔２６，２７，２８に通されると、第３挿通孔２８の近傍において肉厚部４１のうちの肉厚部４１ｂ〈図２参照〉が端部１７のうちの前方へ向かう部分に当接することによって、図３に例示のバックル１８ほどに顕著ではないが、突起部２３が挿入されている透孔２２の周縁部分に張力が集中することを避けることができる。   FIG. 5 is a view similar to FIG. 3 showing one embodiment of the buckle 18 that can be used for the underwater glasses 1 according to the present invention. In the buckle 18, the protrusion 23 is formed in the second partition portion 34. In the underwater glasses 1 using the buckle 18, as shown in FIG. 2, when the end portion 17 of the headband portion 4 is passed through the first, second, and third insertion holes 26, 27, and 28. In the vicinity of the third insertion hole 28, the thick portion 41b of the thick portion 41 <see FIG. 2> contacts the forward portion of the end portion 17 so that the buckle 18 illustrated in FIG. Although it is not remarkable, it can avoid that tension | tensile_strength concentrates on the peripheral part of the through-hole 22 in which the projection part 23 is inserted.

この発明によれば、ヘッドバンド部がレンズ部の外端部分から簡単には外れることのない水中眼鏡の製造が可能になる。   According to the present invention, it is possible to manufacture underwater spectacles in which the headband portion is not easily detached from the outer end portion of the lens portion.
