Description
BACKGROUND OF THE INVENTION
1. Field of the Invention

This invention relates generally to swimming aids. More particularly, the invention relates to a device useful in swimming and a swim aid device for supplementing the buoyancy of a swimmer while allowing free leg and arm movements.


2. Description of the Related Art

In markets today, there are very limited products offered for swimming aids and devices to help novice swimmer control buoyancy while learning to move about in water and learning to swim. In trying to teach beginner swimmers these skills, single devices or various devices can be used in conjunction. A common problem with these devices is the fact that they restrict either upper body movement or lower body movement. In addition, there are no solutions on the market today that aid a swimmer while helping him or her to remain buoyant on their own.


Other solutions on the market can be bulky or sometimes come off a person's body easily while in the water. Several types of swimming aides exist to aid swim students in learning to swim. Some of these devices include flat flutter boards, which are typically composed of a foam and buoy the student during kicking-type exercises. Flutter boards may be difficult to grasp while practicing kicking strokes and uncomfortable to rest on. Other devices such as arm buoys do not help swimmers staying afloat at an angle which would allow them to swim and move about a body of water freely. Other flotation devices, for example, pool noodles, do not hold a solid form, are unwieldy when practicing many types of strokes, and are not comfortable when supporting the swimmer's body.


Currently, there are no useful alternatives that effectively assist a beginner swimmer in learning to swim properly. As will be disclosed below, the present disclosure addresses these needs and covers a device and method which allows a person to remain afloat at a desired swimming angle while allowing for free arm and leg movement to prevent these inconveniences and solve these issues.


SUMMARY OF THE INVENTION

In one aspect, the present invention is embodied as a swim aid device which helps a person float at a desired angle. The device includes a belt to be worn around a person's body and the belt is coupled to two floats. The floats are hollow for buoyancy. The present disclosure allows for arm movement and side to side movement of a person and does not restrict neither arm movement nor leg movement.


In one embodiment, the present disclosure is a swim aid device comprising a belt having a first end and a second end terminating in tabs and one or more hollow floats securely coupled to the belt such that when a user is immersed, the one or more floats remain coupled to said belt. In some embodiments, the belt terminates in clips which are adapted to be coupled to the floats and ensure that the floats remain securely attached to the belt even if a user jumps into the water or moves about a lot. The belt can be rigid or soft and can include a protruding front end for added buoyancy and for ease of use. In some embodiments, the floats include clip attachments adapted to engage with the belt clips and further ensure that the floats remain securely attached to the device at all times.


In some embodiments, the one or more floats include a protruding element at the bottom end of the float to help a swimmer remain at a desired angle when in the water, and to ensure that a user's head does not get submerged when swimming.

In some embodiments such as the ones showing in FIGS. 11 through 15, the belt 150 is a flexibly rigid belt made with hardened materials such that the floats can attach to the belt without the need of additional external clips or components to secure the floats to the belt. The flexibly rigid belt allows a user to pull the belt open, place it around a person's waist and the rigidity of the belt allows the belt to take back its shape after being worn and remains around a person's body and waist.


In other embodiments not depicted here, the belt is made of a soft and flexible material and the buoyant elements are inserted within the belt 150.


In one embodiment such as the one shown in FIG. 14, the rigid belt 150 terminates in two stop portions 157 to keep the buoyant elements 120 within the belt 150. In other embodiments such as the one shown in FIG. 13, the belt terminates in two stop portions 157a and 157b. In one particular embodiment, the belt also includes clip tabs providing additional means of securing the buoyant elements 120 to the belt 150. Here, the clips hold the floats in place and on the belt and ensure that the floats do not slip out when being used.


In some embodiments, the device terminates in clips which are adapted to be coupled to the floats and ensure that the floats remain securely attached to the belt even if a user jumps into the water or moves about a lot. The belt can be rigid or soft and can include a protruding front end for added buoyancy and for ease of use. In some embodiments, the floats include clip attachments adapted to engage with the belt clips and further ensure that the floats remain securely attached to the device at all times.


In some embodiments, the belt is not buoyant while in other embodiments, the belt is lightly or very buoyant. In embodiments where the belt is buoyant, the floats are adapted to adjust for the buoyancy of the belt such that the entire device allows the user to swim freely about a body of water while maintaining an optimal angled position when in the water.


In some embodiments, the belt 150 includes a belt front end 53. When the belt includes a front end 153 and a front protrusion 110 such as the ones depicted in FIG. 13, the entire device's buoyancy remains optimal. Other embodiments do not include a device front end. In all embodiments, the device's edges are soft and comfortable for prolonged wearing in all environments.


Most embodiments include a pair of buoyant elements 120 attached to the back of the belt 150. The floats include a float clip attachment which allows the floats to be securely attached to the belt such that the floats do not separate from the belt under extreme use, jumping in the water with full force or other use cases for children's use in water. Thanks to float clip attachments, the floats are securely and stably attached to the belt.


In some embodiments, the one or more buoyant elements include a protruding element 128 at the bottom end of the float to help a swimmer remain at a desired angle when in the water, and to ensure that a user's head does not get submerged when swimming. These protruding elements also help keep a user afloat with the forward portion of their body above water. FIGS. 8 and 9 show two various embodiments of the buoyant elements. While in some embodiments, the protruding element 128 extend radially outward at the end of the float as shown in FIG. 8, in other embodiments, the protruding element extends at one given radius and protrudes out in one size while in other embodiments, the protrusion grows radially outward the further away it is from the main body of the float.


In some embodiments, the floats are inserted into a tab portion of the belt and remain securely attached to the belt. In other embodiments, the floats are clipped onto the belt, snapped onto the belt, hooked onto, clicked onto the belt, secured thanks to external attachment means and/or inserted into the belt and the belt tab expands outwardly once the floats are in to ensure that the floats remain securely attached to the belt.


In other embodiments, the floats include indentations complementary with protrusions on the belt for coupling. Here the floats remain securely attached to the belt. In other embodiments, the floats expand tubularly outwardly. In these specific embodiments, the volume distribution of air remains optimal to ensure that a user is afloat with the forward portion of the body raised above water for proper breathing.


In some embodiments, the device is tapered, and the edges are softened for comfort and can softly be removed.


In accordance with one form of this disclosure, there is provided a method for using a swim aid device where a user wears said device around a person's body. The belt comprises opening between two floats and a user can stretch the belt to wear it around the waist. The rigid belt allows for the device to be worn around the body without a need for a closure mechanism. The floats are worn around the back of a user.


As mentioned above, other embodiments and configurations may be devised without departing from the spirit of the invention and the scope of the appended claims.
