Description

TECHNICAL FIELD

The present specification generally relates to an underwater (aquatic) exercise equipment assembly and, more specifically to an aquatic exercise equipment assembly that provides a paddle assembly for an upper body movement and a pedal assembly for a lower body movement.

BACKGROUND

In the exercise and fitness field, there are various known devices to assist users to exercise and maintain physical fitness. Further, it is known that aquatic therapeutic rehabilitation equipment is used for assisting physical therapists in rehabilitating persons or assisting in physical fitness. Water provides an environment that reduces a body weight of the user thereby decreasing musculoskeletal stress or impact on the body. As such, soreness of the user may be reduced following the exercise or fitness. However, these known aquatic devices generally do not provide the user with a full body workout. Further, these known aquatic devices do not cater to those with underlying conditions, such as those suffering from arthritis, acute injuries, neurological disorders, stroke symptoms, and the like.

Accordingly, a need exists for alternative aquatic exercise equipment assemblies that provide the user with a full body workout and that assist those with underlying conditions.

SUMMARY

In one embodiment, an aquatic exercising assembly is provided. The aquatic exercising assembly includes a container having a liquid retention portion. The liquid retention portion includes a bottom wall, a pair of opposing sidewalls, and a pair of opposing end walls, a pedal assembly and a paddle assembly. The pedal assembly is rotatably coupled to the one of the pair of opposing end walls. The paddle assembly is coupled to each one of the pair of opposing sidewalls. The paddle assembly is movable between a rearward position and a forward position in a longitudinal direction. The pedal assembly is rotatably moved by a lower body movement of a user and the paddle assembly is moved by an upper body movement of the user.

In another embodiment, an aquatic exercising assembly is provided. The aquatic exercising assembly includes a container having a liquid retention portion and a plurality of ascending stairs. The liquid retention portion includes a bottom wall, a pair of opposing sidewalls, and a pair of opposing end walls, a pair of descending steps, a pedal assembly and a paddle assembly. The pair of descending steps are formed from one of the pair of opposing end walls. The pedal assembly is rotatably coupled to the one of the pair of opposing end walls. The paddle assembly is coupled to each one of the pair of opposing sidewalls. The paddle assembly is movable between a rearward position and a forward position in a longitudinal direction. The pedal assembly is rotatably moved by a lower body movement of a user and the paddle assembly is moved by an upper body movement of the user.

In yet another embodiment, a method for using the aquatic exercising assembly is provided. The method includes entering, via a plurality of ascending stairs and a pair of descending step, a liquid retention portion of a container, sitting onto a lower step of the pair of descending steps, and positioning a pair of feet onto a pedal assembly. The method continues by gripping a handle portion of a paddle assembly, rotating the pedal assembly via the pair of feet, and moving the paddle assembly between a rearward position and a forward position in a longitudinal direction.

DETAILED DESCRIPTION

Embodiments described herein are generally directed to an aquatic exercise equipment assembly. The aquatic exercise equipment assembly is a container in a closed system with a liquid retention portion to hold a liquid, such as water, and a user. As such, the user receives the benefits of non-weight bearing health benefit through buoyancy of the liquid, such as water. The liquid retention portion includes a sitting portion for the user to position thereon. Further, within the liquid retention portion is a paddle assembly for an upper body movement and a pedal assembly for a lower body movement. The paddle assembly is a pair of independently movable paddles that are rotatable between a forward and rearward position. The pedal assembly includes a pair of pedals that are rotatable movable. It should be appreciated that the resistance of paddle assembly and the pedal assembly is caused from the resistance of the liquid, such as water, within the liquid retention portion. Moreover, it should be understood that the paddle assembly and the pedal assembly assist users through controlled ranges of motion or specific movements that are desirable for each user.

Further, the aquatic exercise equipment assembly includes a filtration system that allows for the continuous use of treated liquids, such as water, between users. In addition, the buoyancy of the liquid may be adjusted for particular users using the filtration system. Further, the liquid temperature may be adjusted to meet specific needs of individual users. For example, warm liquid used in aquatic therapy reduces spasticity and relaxes muscles thereby allowing individuals to move with greater mobility and less pain. As such, users gain the general benefits of exercise without suffering from the compressive and torque forces associated with the gravity of a dryland exercise setting.

As used herein, the term “communicatively coupled” means that coupled components are capable of exchanging data signals and/or electric signals with one another such as, for example, electrical signals via conductive medium, electromagnetic signals via air, optical signals via optical waveguides electrical energy via conductive medium or a non-conductive medium, data signals wirelessly and/or via conductive medium or a non-conductive medium and the like.

As used herein, the term “longitudinal direction” refers to the forward-rearward direction of the aquatic exercise equipment assembly (i.e., in the +/−X-direction depicted in FIG. 1). The term “lateral direction” refers to the cross direction of the aquatic exercise equipment assembly (i.e., in the +/−Y-direction depicted in FIG. 1), and is transverse to the longitudinal direction. The term “vertical direction” or “below” or “above” refer to the upward-downward direction of the aquatic exercise equipment assembly (i.e., in the +/−Z-direction depicted in FIG. 1).

Referring now to FIGS. 1-7 and 11-13, an aquatic exercise equipment assembly 10 is schematically depicted. The aquatic exercise equipment assembly 10 includes a container 12.
