The invention relates to a valve system ( 10 ) for a breathing aid for swimmers, in particular for an inhalation valve, comprising a valve housing ( 1 ) and a valve diaphragm ( 2 ) in the valve housing ( 1 ); in a contact zone ( 3 ) preferably located in a central area of the valve diaphragm ( 2 ), the valve diaphragm ( 2 ) is disposed on a first end ( 4 ) of a fastening element ( 5 ); furthermore, from the contact zone ( 3 ), the valve diaphragm ( 2 ) runs at least partially at an angle in the direction of a second end ( 6 ) of the fastening element ( 5 ).
1. A mouthpiece system ( 20 ) for a breathing aid ( 60 ) for swimmers, comprising a mouthpiece ( 21 ), a system housing ( 22 ), an exhalation valve ( 23 ) through which exhaled air flows, and an air outlet opening ( 24 ), with the air outlet opening ( 24 ) being covered by a diffusor extension ( 25 ) comprising a diffusor plate ( 26 ), and the diffusor plate ( 26 ) having a plurality of circular and/or oval and/or elliptical openings ( 27 ), each of the openings ( 27 ) being formed as one of a capillary and a duct wherein the diffusor plate ( 26 ) has an inner surface ( 28 ) facing the exhalation valve ( 23 ), and an outer surface ( 29 ) facing away from the exhalation valve ( 23 ), with the openings ( 27 ) in the diffusor plate ( 26 ) extending transversely from the inner surface ( 28 ) to the outer surface ( 29 ); and
wherein each of the openings ( 27 ) is disposed in the same direction at an angle (δ) offset 5°-89° from an axis normal to the inner surface ( 28 ) of the diffusor plate ( 26 ) so that, when the mouthpiece system ( 20 ) is worn by the swimmer, the exhaled air is directed angularly downwardly away from the swimmer's face.
2. The mouthpiece system ( 20 ) according to claim 1 , characterized in that
the mouthpiece ( 21 ) is firmly locked onto the system housing ( 22 ).
3. The mouthpiece system ( 20 ) according to claim 1 , characterized in that
each of the openings ( 27 ) is disposed in the same direction at an angle (δ) offset 40°-85° from an axis normal to the inner surface ( 28 ) of the diffusor plate ( 26 ) so that, when the mouthpiece system ( 20 ) is worn by the swimmer, the exhaled air is directed angularly downwardly away from the swimmer's face.
4. The mouthpiece system ( 20 ) according to claim 3 , characterized in that
the angle (δ) is adaptable to the swimmer.
5. The mouthpiece system ( 20 ) according to claim 1 ,
characterized in that
the diffusor plate ( 26 ) and/or the diffusor extension ( 25 ) is/are mounted on the system housing ( 22 ) to be exchangeable.
6. The mouthpiece system ( 20 ) according to claim 1 ,
characterized in that
the system housing ( 21 ) has two opposing lateral openings ( 32 ), in each of which a snorkeling tube ( 40 ) is mounted to be rotatable.
7. A breathing aid ( 60 ) for swimmers, comprising at least two snorkeling tubes ( 40 ), a mouthpiece system ( 20 ) according to claim 1 , and a head attachment system ( 61 ) with two elongated fastening elements ( 62 ), each comprising a first end portion ( 63 ) and a second end portion ( 64 ), wherein in each case the first end portion ( 63 ) of one fastening element ( 62 ) is fastened or can be fastened to each snorkeling tube ( 40 ), with the position of the second end portions ( 62 ) being mutually adjustable by a latching system.
8. The breathing aid ( 60 ) according to claim 7 ,
characterized in that
the snorkeling tubes ( 40 ) are mounted to be rotatable in a system housing ( 22 ) of the mouthpiece system ( 20 ).
9. The breathing aid ( 60 ) according to claim 7 ,
characterized in that
a snorkeling tube ( 40 ) has a groove-shaped depression ( 66 ) on a tube area section ( 65 ) facing the head of a swimmer, with the first end portion ( 63 ) of a fastening element ( 62 ) being positionable in the depression ( 66 ) in a rail-like manner.
10. The breathing aid ( 60 ) according to claim 9 ,
characterized in that
the first end portion ( 63 ) of a fastening element ( 62 ) has a plurality of recesses ( 67 ) and the first end portion ( 63 ) is fastened or can be fastened in the depression ( 66 ) by a fastening means ( 68 ) that can be introduced into at least one of the recesses ( 67 ).
11. The breathing aid ( 60 ) according to claim 7 ,
characterized in that
the latching system comprises a turning knob ( 69 ) and/or a ratchet lever.
12. The breathing aid ( 60 ) according to claim 7 ,
characterized in that
on the side of the head attachment system ( 61 ) facing the head of a swimmer, a head contact plate ( 80 ) is formed in the area of the latching system.
13. The breathing aid ( 60 ) according to claim 7 ,
characterized in that
in the breathing aid's ( 60 ) state of use, the turning knob ( 69 ) and/or the ratchet lever is/are situated in relation to a dental support plate ( 82 ) of a mouthpiece ( 21 ) on a line arranged at an angle (Ω) of 30°-60° to the dental support plate ( 82 ).
