No. 62/708,626, filed on Dec. 15, 2017 and titled “SNORKEL WITH VERTICALLY ADJUSTABLE HEAD-STRAP” is hereby incorporated by reference.

FIELD OF THE INVENTION

This invention relates to swimming equipment. More particularly, the present invention relates to snorkels and snorkel systems for lap swimming in a pool.

BACKGROUND OF THE INVENTION

A number of conventional snorkel and snorkel systems are available. For example, there are a number of side-mounting snorkels that are configured to secure to a pair of goggles while snorkeling or swimming. These conventional or side-mounted snorkels are available with a number of simple or sophisticated mouth-pieces and mechanisms to prevent the flow of water into the breathing tube of the snorkel.
Conventional or side-mounted snorkels provide a high degree of drag and are not well suited for swimming and lap training in a swimming pool. Accordingly, there is a continued need to develop snorkels and snorkel systems that are configured for swimming and lap training in a swimming pool.

SUMMARY OF THE INVENTION

A swimmer's technique needs to be perfected in order for the swimmer to be competitive. One training technique involves isolation of various aspects of swimming. With this training technique, a swimmer trains by concentrating on some aspect of swimming, while ignoring other aspects. For example, a swimmer uses a float board to practice kicking motion of the legs, while ignoring arm strokes. Likewise, the swimmer can train with a snorkel. Training with a snorkel allows the swimmer to focus on kicks and arm strokes without having to concentrate on breathing techniques, which requires the swimmer to turn his head and inhale while his mouth is out of the water. Further, swimming with a snorkel also allows the swimmer to become comfortable with his or her face submersed in the water for extended periods of time.
Conventional or side-mounted snorkels can interfere with the swimmers arm stroke and tend to provide too much drag through the water to allow for the accurate evaluation of a swimmers lap time. A front or center-mounted snorkel, such as illustrated by Mix in U.S. Pat. No. 7,234,461 and Garraffa in U.S. Pat. No. Des. 406,333 provides some improvements over the conventional or side-mounted snorkel for use in lap training. The front or center-mounted snorkel of Mix or Garraffa does not interfere with the swimmers arm stroke and has a streamlined breathing tube that reduces drag through the water.
The present invention is directed to a snorkel with a hollow arching or curved breathing tube with a mouth-piece end and a breathing port end. The hollow arching or curved breathing tube is preferably made from plastic that is flexible, rigid or semi-rigid. The cross-section of the arching or curved breathing tube can be flattened, round oval or have any other number of shapes. Attached to a mid-section of the arching or curved breathing tube is a bracket member. The bracket member has one or more apertures for threading one or more head-straps therethrough. The head-strap preferably has a clip member for connecting ends of the one or more of the head-straps together and/or for adjusting the lengths or sizes of the one or more head-straps. The bracket member can have any suitable shape, but preferably is a yoke-shaped structure with a curved interior surface that contours to a portion of a user's head while wearing the snorkel.
Attached to the mouth-piece end there is a elbow-shaped hollow breathing tube member with a with a mouth-piece for holding the snorkel in a user's mouth. The elbow-shaped hollow breathing tube member is configured to rotate or swivel with respect to the hollow arching or curved breathing tube such that the mouth-piece can be rotated out of the way when the snorkel is not being used.
In an embodiment of the invention the bracket portion of the snorkel breathing tube has set of metered apertures, such the one or more head-straps can be treaded through selected apertures within the set of apertures to host a range or vertical positions along the snorkel breathing tube. In yet further embodiments of the invention snorkel has an adjustment mechanism couple to the bracket member. The adjustment mechanism includes ratchet, slotted or notched features, and/or mated tongue and groove features that allows the bracket member to be slidably adjusted up and down along fixed positions along the mid-section of snorkel breathing tube and allows the bracket member to be lock one of the selected and fixed positions.

FIGS. 2A-B show schematic representations of adjustment mechanisms for adjusting the vertical positions of one or more head-strap along a breathing tube of a snorkel, in accordance with the embodiments of the invention.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1A-B, a snorkel 100 of the present invention includes a hollow arching or curved breathing tube 101, hereafter arching breathing tube 101, with a mouth-piece end 109 and an opposed breathing port end. The arching breathing tube 101 is preferably made from plastic or other polymeric material that is flexible, rigid or semi-rigid. The arching breathing tube 101 can be made in parts that fit together or formed as a monolithic unit. The cross-section of the arching breathing tube 101 can be flattened, round, oval or have any number of different shapes or combinations of shapes.
Attached to a interior mid-section arching breathing tube 101 is a bracket member 107. The bracket member 107 has one or more apertures 108 for threading one or more head-straps 111 therethrough. The one or more head-straps 111 preferably have one or more clip members 113 for connecting ends of the one or more of the head-straps 111 together and/or for adjusting the lengths or sizes of the one or more head-straps 111. The bracket member 107 can have any suitable shape, but preferably is a yoke-shaped structure with a curved interior surface that contours to a portion of a user's head while wearing the snorkel 100. The bracket member 107 can be monolithic with the arching breathing tube 101 but is preferably formed as separate structure that is coupled to or attached to the mid-section 106′ and 106″ (FIGS. 2A-B) of arching breathing tube 101 through ratcheting clips and snaps, sliding tongue and groove structures and/or any other suitable mechanism. Regardless of the attachment mechanism used, the vertical position of the bracket member 107 along the mid-section arching breathing tube 101 is preferably adjustable, such as described below.
Attached to the mouth-piece end 109 of the arching or curved breathing tube 101 there is a elbow-shaped hollow breathing tube mouth-piece adapter 109, hereafter mouth-piece adapter. Attached to the mouth-piece adapter 103, there is a mouth-piece 105 for holding the snorkel 100 in a user's mouth when the snorkel is downed. The mouth-piece adapter 109 is preferably configured to swivel (swiveling mouth-piece) with respect to the arching breathing tube 101, as indicate by arrow 117 in FIG. 1A and shown in FIG. 1B. In operation the mouth-piece 105 can be rotated out of the way via the mouth-piece adapter 103, when the snorkel is not being used but remains fixed on a user's head.
