ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an exercising device and more particularly to an ankle, leg and hip exercising device.
2. Description of the Related Art
Many types of ankle exercising devices have been previously provided which are designed to enable a person to exercise his/her ankle in an effort to rehabilitate the same. Heretofore, most of the prior art ankle exercising devices only enabled the ankle to be exercised in a fore and aft manner and not in a side-to-side manner. Further, the prior art ankle exercising devices do not have any means associated therewith for increasing or decreasing the resistance of movement to the ankle in a 360° motion. Additionally, the prior art devices do not include any mechanism whereby the person could actually assist the movement of the person's ankle by means other than flexing of the ankle. Additionally, the prior art devices are not believed to have the capability of permitting the ankle to be exercised while the person is standing, sitting or reclining. Yet another disadvantage of the prior art devices is that they are not believed to have the capability of permitting the exercising of the ankle, leg and hip.
SUMMARY OF THE INVENTION
An ankle, leg and hip exercising device is disclosed comprising a lower portion having an upper and a parabolic-shaped lower end whereby the lower end may be selectively positioned on a supporting surface so as to have a full range of movement with respect thereto. A foot supporting and retaining portion is provided at the upper end of the lower portion for supporting and retaining a person's foot therein. At least one exercise attachment receiving means is provided on the foot supporting and retaining portion and preferably includes a means for receiving a weight thereon. Further, the exercise attachment receiving means comprises an upstanding pipe stub adapted to have a first elongated tubular member, having upper and lower ends, having its lower end received by the pipe stub and extending upwardly therefrom. The upper end of the tubular member has a first grip portion thereon to enable the person using the device to either move the device to flex the ankle or to create resistance to the flexing of the ankle. When additional resistance is required, a second tubular member may be slipped over the first tubular member to increase the rigidity thereof. In the preferred embodiment, the foot supporting and retaining portion is selectively removably secured to the lower portion and includes a recessed portion which receives the foot of the person utilizing the device. A heel retainer is also adjustably positioned over the U-shaped member which extends over the forward portion of the person's foot.
OBJECTS OF THE INVENTION
It is principal object of this invention to provide an ankle exercising device.
Yet another object of the invention is to provide an ankle, leg and hip exercising device.
Yet another object of the invention is to provide an ankle, leg and hip exercising device which includes a parabolic-shaped member which engages a supporting surface to enable the device to be moved in a 360° manner.
Still another object of the invention is to provide an ankle, leg and hip exercising device which securely positions the user's foot therein.
Yet another object of the invention is to provide an ankle, leg and hip exercising device including a heel retaining means.
Yet another object of the invention is to provide an ankle, leg and hip exercising device including exercise attachment receiving means mounted thereon.
Yet another object of the invention is to provide an ankle, leg and hip exercising device including an upwardly extending tubular member having a hand grip on the upper end thereof which enables the user to resist the movement of the device or to cause movement of the device.
Still another object of the invention is to provide an ankle, leg and hip exercising device which may be used while standing, sitting or reclining.
Still another object of the invention is to provide an ankle, leg and hip exercising device including means for supporting weights thereon so that the weights may be positioned at different angles with respect to the ankle.
Still another object of the invention is to provide an ankle, leg and hip exercising device which permits the ankle to be exercised in a 360° manner.
Still another object of the invention is to provide an ankle, leg and hip exercising device which is conveniently attached to the user's foot.
These and other objects will be obvious to those skilled in the art.
