Description

FIELD OF THE INVENTION

The inventive concept relates generally to a buoyancy-adjustable swim training vest.

BACKGROUND

Currently, there are a number of solutions for swim training flotation aids. One of these solutions is inflatable water wings worn around children's arms, but this solution fails to meet the needs of the market because water wings obstruct the movement of the arms when the child attempts to swim. Another solution attempts to utilize a traditional life vest, but this solution is similarly unable to meet the needs of the market because a traditional life vest is too buoyant and may limit the movement of the arms and the head. Still another solution is to rely on a trainer to monitor the children, but this solution may fail if the monitor is not suitably prepared. Therefore, there currently exists a need in the market for an improved buoyant vest for training children to swim.

SUMMARY

A buoyancy-adjustable swim training vest for a user has a sleeveless (optional, in a related embodiment sleeves are included) garment member designed to substantially circumscribe the user's torso from substantially the neck to the waist, the sleeveless garment member further comprising substantially a neoprene fabric (or polymer-neoprene fabric blend, but not limited to such). A front portion of the sleeveless garment member has, at a lower front portion of the sleeveless garment member, a front cover member that is removably coupled to an outer surface of the lower front portion of the sleeveless garment member by a first hook and loop assembly disposed on an interior face of the front cover member and disposed on the outer surface of the lower front portion of the sleeveless garment member, the front cover member pivotally and horizontally coupled to a middle front portion of the sleeveless garment member so as to be vertically liftable to expose the outer face of the lower front portion of the sleeveless garment member thereunder.

A back portion of the sleeveless garment member coupled to the front portion of the sleeveless garment member by a right shoulder portion and a left shoulder portion has a right side elastic wing member and a left side elastic wing member, the wing members horizontally aligned and extending from a lower back portion of the sleeveless garment member, a second hook and loop assembly disposed on front and back surfaces of the wing members, the wing members designed to wrap frontward around the user's torso and detachably couple by respective hook and loop assemblies to each other, to the outer surface of the lower front portion of the sleeveless garment member, and to the interior face of the front cover member of the lower front portion of the sleeveless garment member, the outer ends of the wing members overlapping each other and disposed between the interior surface of the front cover member and the outer face of the lower front portion of the sleeveless garment member.

Some embodiments of the inventive concept lack the front cover member and are secured around the user's torso with the wing members exposed.

One of ordinary skill in the art would recognize that other attachment methods could be used such as buckle, clip, and strap assemblies, ties, buckle and belt assemblies, flexible strips of metal or plastic with interlocking projections closed or opened by pulling a slide along them (zippers), or the buoyancy-adjustable swim training vest may be pulled over the wearer's head as would be a pullover shirt, may have elastic bands to make pulling over easier and to retain a tighter grasp around the body, and, therefore, may operate without attachment assemblies. Combinations of attachment assemblies may be used such as a hook and loop assembly supplemented by a buckle, clip, and strap assembly. Portions of the buoyancy-adjustable swim training vest may be made from materials other than neoprene to accommodate wearing and attachment methods. A fabric covering material for the neoprene may also be a part of the structural design.

An at least one polymer strap member may be coupled at a distal portion of the at least one strap member to the lower back portion of the sleeveless garment member at a horizontally centered position of the sleeveless garment member, the at least one strap member designed to detachably and adjustably couple by a latch portion coupled to a proximal end of the at least one strap member to an at least one buckle member, the at least one buckle member coupled to a lower edge portion of the front portion of the sleeveless garment member, the at least one strap member, when in a coupled state, designed to circumscribe the user's crotch. An at least one substantially sealable back pocket member is disposed on an outer surface of the lower back portion of the sleeveless garment member designed to hold at least one removable back buoyant pad member. The sealable back pocket member may, when in use or stored, hold no buoyant pad members. In this example instance, the vest itself may have buoyancy inherent in the neoprene.

A buoyant pad member is an insert that may be made from neoprene, a polymer foam, a polystyrene, an air bladder or bubble assembly, or other buoyant material. In one embodiment, the buoyant pad member is a polymer foam substantially one quarter inch thick. The addition or removal of buoyant pad members allows the buoyancy of the buoyancy-adjustable swimming training vest to be adjustable. The associated process is to remove buoyancy pads as a given child improves swimming skills and gains confidence in those skills.

In one embodiment of the buoyancy-adjustable swim training vest, at least one front pocket member is disposed on an outer surface of the front portion of the sleeveless garment member designed to hold at least one removable front buoyant pad member. In one embodiment, there are two front pocket members designed to hold up to three each buoyant pad members. The sealable back pocket member may, when in use or stored, hold no buoyant pad members.

In one embodiment of the buoyancy-adjustable swim training vest, a second pocket member is disposed substantially on the lower back portion of the sleeveless garment member designed to store the at least one strap member therein.

In one embodiment of the buoyancy-adjustable swim training vest for a user, there are three each removable back buoyant pad members designed to be disposed within the at least one back pocket member.

It would be advantageous to have a buoyancy-adjustable swim training vest that is adjustable for many sized people. Furthermore, it would also be advantageous to have a buoyancy-adjustable swim training vest that is substantially colored orange or yellow. Still further, it would be advantageous to have a buoyancy-adjustable swim training vest that allows free movement of arms and legs.

The inventive concept advantageously fills the aforementioned deficiencies by providing a buoyancy-adjustable swim training vest, which provides added flotation to help teach children to swim and to help keep children safe by adding buoyancy.

The buoyancy-adjustable swim training vest fulfills the need for added buoyancy to help teach children to swim. The inventive concept may be used for adults and may be made in several sizes.

Among other things, it is an advantage of the buoyancy-adjustable swim training vest to provide buoyancy for swim training that does not suffer from problems or deficiencies associated with prior solutions.

One of ordinary skill in the art would recognize that other fasters could be used beside hook and loop assemblies such as clips, buckles, ties, and zippers to fasten certain elements or to provide supplementary fasteners to the hook and loop assemblies.

Neoprene is a synthetic polymer resembling rubber, resistant to oil, heat, and weathering. It has buoyant properties by capturing microbubbles within fabric pores. Neoprene also offers insulating properties which may afford a further benefit for training children to swim if the water is colder than normal human body temperature.

The inventive concept now will be described more fully hereinafter with reference to the accompanying drawings, which are intended to be read in conjunction with both this summary, the detailed description, and any preferred and/or particular embodiments specifically discussed or otherwise disclosed. This inventive concept may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of illustration only and so that this disclosure will be thorough, complete, and will fully convey the full scope of the inventive concept to those skilled in the art.
