Aquatic exercise weight
| Details |
Inventors: Wheeler, Robert L.;
Assignee:
Primary Examiner: Apley; Richard J.
Assistant Examiner: LaMarca; William
Attorney, Agent or Firm: Smith; Ronald E.
An aquatic exercise device for use by an exerciser standing in a natural or man-made body of water. The device includes containers that fill with water when immersed and which have drainage openings formed in them so that they drain when lifted out of the body of water. The exercise device may include a single container that is lifted from the body of water by a pulley and cable mechanism, or it may include a single container connected to a rigid bar, mid-length of the bar, or it may be provided in the form of a barbell or a dumbbell having water containers at opposite ends of a rigid bar. In all embodiments, the flow rate of water draining from the container or containers may be adjusted to a flow rate selected by the exerciser. In the barbell, dumbbell, and central container embodiments, the containers are rotatably and eccentrically mounted with respect to an elongate or short or medium length bar, respectively, so that they invert when initially immersed and return to their repose position when lifted from the body of water, aligning the drain holes of the containers in their respective proper positions so that the containers drain at the same rate when lifted out of the water. The size, number and location of the fill and drainage openings may be varied. In all embodiments, the rigid bar is hollow and buoyant. |

DETAILED DESCRIPTION The longstanding but heretofore unfulfilled need for an apparatus that overcomes the limitations of the prior art is now met by a new, useful, and nonobvious invention.
In a first embodiment, the present invention includes a rigid bar of predetermined extent and a container means including a first container rotatably attached to a first end of the rigid bar and a second container rotatably attached to a second end of the rigid bar.
Suitable means are provided for eccentrically attaching the first and second containers to the first and second opposite ends, respectively, so that the containers assume their respective positions of equilibrium when in repose; the center of gravity of each container is below the rigid bar.
The novel stucture further includes a first aperture means formed in each of the containers for admitting water thereinto when the containers are immersed in a body of water and a second aperture means formed in each container for draining water therefrom when the containers are lifted from the body of water.
In this way, the containers are at least partially filled when immersed in a body of water for a predetermined period of time, and water in the containers is drained therefrom when the containers are lifted from the body of water so that the weight of the exercise device, upon being lifted from the water, diminishes over time.
Significantly, the weight of the novel device is at a maximum at the moment it is separated from the water surface so that maximum training benefits are achieved by the exerciser at the beginning of the weight-lifting procedure.
The weight of the novel device is at a minimum after it has been held out of the water for a length of time sufficient to allow complete drainage of water from the containers.
Thus, the exerciser can lower the device comfortably and safely.
If the exerciser prefers to simply drop the device or throw it down after the containers have been emptied, no harm is done.
The means for eccentrically attaching each container to the rigid bar includes, in a first embodiment, an eccentric bore formed in each of the containers so that the rigid bar passes through the containers in parallel but offset relation to a centerline of the containers
