ABSTRACT:
FIELD OF THE INVENTION
The invention relates to an exercise device having an adjustable strap which is mountable on a door or wall, and an elastic band. More particularly, the adjustable strap includes a series of loops on one of its sides. Once the adjustable strap has been mounted on a door or wall, an elastic band can be placed through one of the loops and can be pulled or pushed to exercise various muscles.
BACKGROUND OF THE INVENTION
Devices are known in the art which may be used to exercise muscles. These devices, however, have limitations, such as, by way of example only, lack of portability, heavy weight, large size, inconvenient storage, incompatibility, lack of adaptability to different users and/or restriction on muscle groups exercised.
One such apparatus is described in U.S. Pat. No. 5,766,118 issued Jun. 16, 1998 to Conner. The Conner apparatus is used for developing the abdominal muscle group. The Conner apparatus attaches to a vertical surface such as a door or wall using a clamp and includes an elastic resistance band which is formed into a closed loop and a harness which is pulled to exercise the muscles.
U.S. Pat. No. 5,601,518 issued Feb. 11, 1997 to Weintraub discloses a portable exercise device that comprises two bases. Each of these bases attaches to the top and bottom of a door respectively. A bar is pivotally mounted to the bottom base. The bar is attached to a strap on one end and a longitudinally extending biasing means on the other. By pulling on a rod attached to the strap, the user can exercise his or her muscles.
U.S. Pat. No. 5,571,064 issued Nov. 5, 1996 to Holm discloses an exercise device which includes a loop for attachment to an anchoring structure, such as a door, which loop receives an elastic cord, which elastic cord is connected to a handle assembly.
U.S. Pat. No. 5,254,065 issued on Oct. 19, 1993 to Pollock discloses a fastening strap configured as a loop securable between a door and its associated frame. The strap is used for support of exercise.
U.S. Pat. No. 4,830,365 issued on May 16, 1989 to March discloses an exercise device for home use for attachment to a suitable surface, such as a door, having a vertical tubular housing with spring mechanism and molded piston assembly inside, to which is attached a rope with various handle means for exercise.
U.S. Pat. No. 5, 662,563 issued on Sep. 2, 1997 to Maerzke discloses a portable exercise device comprising a flexible elastic material strap gripped by three rods held together by removable caps at each end.
It is apparent that an exercise apparatus that overcomes one or more of the limitations of the exercise apparatus described above would be advantageous.
SUMMARY OF THE INVENTION
The invention is an adjustable strap and band exercise device which is mountable on a door, wall or suitable structure. More particularly, the invention comprises an adjustable strap with a series of loops which may be mounted on a door through a locking mechanism, and an elastic band which is insertable through a selected loop of the adjustable strap. The adjustable strap includes a series of loops on one of its sides. After the adjustable strap has been mounted on the door by use of the locking mechanism, the door is closed and preferably locked, and an elastic band can be placed through one of the loops of the adjustable strap. The user may select an appropriate loop of the adjustable strap through which to pass the elastic band based on the user's height or the muscle group which the user desires to exercise. The user may exercise by applying force to the adjustable strap. Before or after use of the invention, the adjustable strap of the invention may be rolled up to a compact size whereby it may be conveniently carried by a person in his or her pocket.
Accordingly, it is an object of the invention to provide an exercise apparatus which is portable, light weight, compactable and adaptable to be used by people of different sizes and physical strengths.
It is a further object of the invention to provide an exercise apparatus which works a wide range of muscle groups.
It is a further object of the invention to provide an exercise apparatus which is flexible and of inexpensive design.
