LIQUID FILLABLE PORTABLE EXERCISE APPARATUS

Abstract

A liquid filled portable exercise apparatus consisting of a portable assembly that may be easily transportable in a suitcase for travel consisting of a single or multiple removable, resilient and liquid or water fillable bladder center section(s) within a closed form, nearly circular, or elliptical in shape, handle section allowing the user to use it in a similar manner as that of a Kettle Ball as well as a weighted exercise bar. Some implementations can include a handle as well as resilient and collapsible bladders that are designed, without liquid or water, to lay nearly flat in a suitcase and allow for easy attachment of one or more collapsible bladders that can be filled with various levels of liquid or water commensurate with the desired weight required by the user for a specific exercise routine. Typically, the user would completely fill the bladders.

Description

[0001] This application claims priority to U.S. Provisional Patent Application No. 61/583,389, entitled "Liquid Filled Portable Exercise Apparatus," filed on Jan. 5, 2012.

FIELD

[0002] The disclosed subject matter relates generally to athletic equipment, and more particularly to a portable liquid filled exercise apparatus having one or multiple liquid (e.g. water) filled bladder(s) affixed to a generally circular or oval shaped handle where the handle configuration enables a plurality of additional exercises that may not be possible using convention exercise apparatus systems. Additionally, some implementations may provide for user safety, as the components that contain the weight bearing elements, or bladders, are soft and flexible, thereby reducing or minimizing the risk of injury.

BACKGROUND

[0003] Portable exercise equipment, in various forms, have been known for many years. One of the recently more popular types of portable exercise apparatus are various types of portable dumbbells and the like to address the needs of users who want to be able to travel with their equipment. It can be difficult to travel with conventional dumbbells, as they are typically heavy, by design and necessity.

[0004] Accordingly, many types of liquid or water fillable dumbbells, and the like, have become more common recently in order to permit easily carrying of these dumbbells or the like in a suitcase or the like, without taking up too much room or being overly heavy, especially for airline travel.

[0005] One significant problem with liquid or water fillable dumbbells may be the lack of easy adjustability of weight in order to provide the user with a selection of weight values depending on the exercise routine to be performed. Another significant problem may be that a dumbbell set does not offer the same range of exercises as that offered by implementations of the disclosed subject matter

[0006] Conventional exercise devices can include kettle bells, medicine balls, free-weights, and dumb bells. Simple kettle bells and medicine balls are well known in the prior art; however, none of these prior art devices disclose a removable weight system with a closed form handle that can be held with either one or two hands. Additionally, kettle bells may not be safe to use because they are usually fabricated out of hard iron like materials.

[0007] Conventional exercise systems may not include a single device that can be adapted to fulfill the goals of various exercise routines in one portable piece of exercise equipment. Some implementations were conceived in light of the above-mentioned problems and limitations among other things.

SUMMARY

[0008] In general, some implementations may provide an athletic apparatus having one or more weighted, resilient bladder assemblies that can be removably attached to the handle allowing for one-handed or two-handed use. Also, some implementations can include a two handed dumb bell with a resilient construction and the attachment of two handles to one kettle ball-like structure for performing exercises.

[0009] Using the apparatus with two hands provides for an exercise apparatus that can be used in various two handed exercises including, but not limited to: "lift curl and reach", "kneeling side chop", "weighted crunch", "upright row", "skull crusher", "overhead triceps extensions" and/or the like. These exercises allow for various kneeling and stretching exercises to strengthen and stretch the shoulders as well as the upper and lower back.

[0010] The apparatus can be used in various one-handed exercises such as, but not limited to: "kick back", "half get up", "curls", "one arm row", "military press", and "one arm triceps extension".

[0011] Some implementations may provide an athletic apparatus having user advantages, portability features, and safety features. Some implementations may provide an athletic apparatus that enables a great number of exercises through its capability to be safely used with either one or two hands without the need for the user making any modifications to the apparatus. The removable weight system can be secured to the handle using various locking mechanisms.

[0012] Some implementations can include weight bearing elements or bladder assemblies can be easily filled with liquid or water in a standard bathroom sink providing for ease of use. Additionally, in some implementations, the weight bearing elements or bladder assemblies can be easily emptied of liquid or water for fast and easy transport in a suitcase or the like.

[0013] Other features and advantages provided by one or more implementations will become apparent from the following detailed description, taken in conjunction with the accompanying drawings.
