Diving mask

摘要

A diving mask including at least one lens, a facepiece made of a soft and elastically yielding material, provided with at least a front positioning opening that positions the at least one lens, and a rear profiled element that rests on a user's face. Also included is a rigid frame that includes a first frame element and a second frame element anterior to the first frame element, fixed to one another such as to guarantee a seal between the facepiece and the lens. The front positioning opening of the facepiece can exhibit, along a perimeter edge thereof, a hollow positioning flange for the first frame element, the hollow positioning flange extending from an internal side of, and at least partially posteriorly to, the front positioning opening of the facepiece.

1. A diving mask, comprising:
at least one lens including a right lens and a left lens; a facepiece of elastically yielding material, the facepiece including;
at least one front positioning opening that includes a right anterior opening and a left anterior opening, and that positions the at least one lens; anda rear profiled element that rests on a user's face; and a rigid frame including:
a first frame element; anda second frame element anterior to the first frame element, where the first and the second frame elements are fixed to one another to guarantee a seal between the facepiece and the at least one lens; wherein the front positioning opening of the facepiece exhibits, along a perimeter edge thereof, a hollow positioning flange for at least the first frame element, the hollow positioning flange extending from an internal side of, and at least partially posteriorly to, the front positioning opening of the facepiece; wherein the first frame element comprises:
a right annular portion positioned along the hollow positioning flange of the perimeter edge of the right anterior opening of the facepiece, the right annular portion positioning the right lens;a left annular portion positioned along the hollow positioning flange of the perimeter edge of the left anterior opening of the facepiece, the left annular portion positioning the left lens; anda central connecting portion between the right annular portion and the left annular portion, the central connecting portion arranged projectingly from a front surface of the right and the left annular portions; and wherein the hollow positioning flange has a transversal section substantially in an open polygonal spiral shape, and comprises;
a first wall which develops laterally and perpendicularly to the right lens and the left lens;a second wall which extends perpendicularly from the first wall, and parallel to and below the right lens and the left lens;a third wall which extends perpendicularly from the second wall, and perpendicular to and below the right lens and the left lens;a fourth wall having a perimeter rest support for the right lens and the left lens, the fourth wall extending perpendicularly to the third wall and anteriorly to the second wall;a fifth wall, perpendicular to the fourth wall, wherein the fifth wall surrounds the right lens and the left lens; anda sixth wall, extending from the fourth wall symmetrically to the fifth wall.
