Endless elastic resistance exercise device

Abstract

An elastic resistance exercise device includes an endless elastic resistance member that returns to its original or near original shape and length after being stretched. The elastic member is loosely encased by an endless, gathered fabric sleeve that permits the elastic member to stretch several times its original length and also limits the amount of stretch of the elastic member. Two handgrips are connected to the fabric encased elastic member, and the handgrips are made of a material which is soft and compressible by a user and which returns to its original shape or near its original shape after it has been compressed.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. provisional application No. 60 / 786,756, filed Mar. 29, 2006.BACKGROUND OF THE INVENTION[0002]The invention relates to an endless elastic resistance device for use in a variety of applications, including exercise.[0003]There are various elastic devices on the market used for resistance, cardiovascular, flexibility and balance exercises, examples of which are Theraband®, manufactured by Hygienic Corporation; and the Versa-Tube™ line of exercise bands, tubes and cuffs. These devices are effective for a variety of strength, fitness and therapeutic exercises; but there continues to be a need for a circular or endless elastic resistance device that prevents the skin from coming in contact with the elastic member and can be comfortably used by individuals with tender or sensitive skin and joints.[0004]Examples of prior art include the Versa-Tube®, Premium Versa-Tube™, Versa-Tube Pro™, Versa-8™ and Vers...

AI Technical Summary

Benefits of technology

"The present invention is an improved resistance device that provides a comfortable and safe way to exercise. It consists of an elastic resistance member that returns to its original shape when stretched, and a protective sleeve made of less elastic material. The sleeve acts to limit the stretch of the elastic member, protect the user from injury, and make the device easier to use. The resistance member can be covered in fabric or other material to further protect it. The device can be used for a variety of exercise activities and is comfortable for users of different sizes and strengths. The invention also includes hand grips that serve as a resistance medium and an unstable surface for balance training. The hand grips are securely attached to the elastic resistance member and can be used for both anchoring and resistance during exercise activities."

Problems solved by technology

The device is difficult for some exercisers to use for the following reasons: (1) individuals with tender or sensitive joints in the hand, wrist or fingers have a hard time grasping the handles, (2) the elastic tubing can pinch, chafe or irritate the skin, (3) if the tube should break, it could recoil uncontrollably causing injury to the user or bystanders or damage to property, (4) if one of the handles is accidentally released, it could injure the user or bystanders and (5) the tube is too long for many exercises, particularly if the individual performs an exercise when seated.

This practice can inhibit circulation and / or irritate the skin or joints.

Lastly, the handles of these products cannot be used to perform a variety of exercises.

The Premium Versa-Tube™ has padded handles which are more comfortable than hard, plastic handles; however, it requires the user to grip the handles, which may not be possible for exercisers with tender or sensitive joints.

The 48 inch length tube is too long for many exercises traditionally done using an exercise band.

When confronted with a tube that is too long for executing the desired exercise, individuals often wrap the tubing around the hand, which can inhibit blood circulation, pinch or chafe the skin, and lead to poor exercise form.

Additionally, the handles are not designed to be used to perform a variety of exercises.

Although this feature allows the user to customize the length of the band, an individual with tender or sensitive hand joints would have difficulty using the locking system and grasping the hard plastic handles attached to the tube.

In addition, if the tube should break, it could recoil uncontrollably, and if a handle should accidentally be released, it could injure the user or bystanders.

The rubber handles may be difficult for people with sensitive joints to grip, and the handles and tubing can be irritating to individuals with sensitive skin.

The handle design of this product make it unusable for some exercises.

The handles, tube length and likelihood of tube-to-skin contact make exercising with this product difficult for some, such as those with fragile skin, tender or sensitive joints, or those who exercise in a seated position.

In addition, if the band should break, it could recoil uncontrollably, and if the handles should accidentally be released, they could injure the user.

These grips may be uncomfortable for individuals with tender or sensitive joints to use.

When used for certain exercises, such as when the band is used around the legs for abduction exercises, the handles may irritate fragile or delicate skin.

Also, because the tubing is fed through the handles which allow the tube to rotate within the handles, the device has a tendency to roll up the legs during certain exercises.

Although these cuffs are gentler on the skin, their Velcro® or Velcro®-like closure may be difficult for individuals with sore hand joints or those lacking fine motor skill so use.

When they come in contact with the skin, these bands may irritate or pinch the skin during exercise.

If the bands break, they could recoil uncontrollably and injure the user or bystanders.

However, none of these exercise products protect the user from coming in contact with the band or tubing, and the handles are not designed to be used as a modality to perform exercise.
