Foldable abdominal and thigh exercise machine

Foldable abdominal and thigh exercise machine description/claims

This application is entitled to the benefit of Provisional Patent Application titled, “Foldable Abdominal and Thigh Exercise Machine,” filed 2005 Dec. 16.

1. Field of the Invention

This invention relates generally to exercise devices, and more particularly to a device that is to use the weight of a user to provide a resistance for workouts on abdominal, upper arms, and thighs.

2. Description of Related Art

Many abdominal exercise machines have been created in the present time. Some of them also perform other exercises. One type of the machines is a simple board on a floor to support a user's back, and as the user pulls an arm the board moves up to provide a resistance as in a sit-up motion. Sometimes the arm is pulled using the user's legs to move the board upward. This setup usually provide only abdominal workout setting and the user must lie down on the floor. There are other type of machines that allow the user to sit down on a seat pad and a backrest for performing abdominal exercise. A number of them incorporate a movement of either the seat pad or the backrest as the user pulls or pushes the arm. However their setups are usually complicated, expensive to manufacture, and big in size, and only offer abdominal workout option, often without a stowed position for device storage.

The present invention teaches certain benefits in construction and use which give rise to the objectives described below.

The present invention is an apparatus to be used as an exercise device that helps a user to exercise her or his abdominal, upper arm, and thigh muscles using her or his own weight. Adjustments can be made to change one exercise to another. The present invention can be folded to store away into a space such as a closet or a gap between a floor and a bed frame. The apparatus includes a base frame that sits on a floor surface. A seat frame is pivotally attached to the base frame and accommodates a user to sit on a seat pad integrated onto the seat frame. An arm portion is pivotally fixed on the base frame and pivotally linked to the seat frame using a link. When the user sits on or leans against the seat frame and pushes away the arm portion to exercise abdominal, arms, or thighs, the link that pivotally connects the arm portion to the base frame causes the seat frame to rise up lifting the user. This action provides a resistance, the body weight of the user, for the exercise. The arm portion can be adjusted to accommodate the user to focus on abdominal or arm or thigh muscles at a time.

A primary objective of the present invention is to provide an apparatus having advantages not taught by the prior art.

Another objective is to provide such an apparatus capable of utilizing the weight of the user as a resistance using a linkage that connects the base frame, the seat frame, and the arm portion.

Another objective is to provide such an apparatus capable of making adjustment on the position of the arm portion relative to the seat frame such that the user is able to focus on a different muscle group at a time.

A further objective is to provide such an apparatus capable of having it folded so that it can be stored away in a compact space such as a closet space or a space between a floor and a bed frame.

Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

The accompanying drawings illustrate the present invention. In such drawings:
