Abstract

Abstract An exercise device for the lower extremities that can be mounted on a support and has a frame having a first leg and a second leg. The first and second legs have a first end and a second end. The first end of the first and second legs are pivotally connected. A cylinder is connected to the first and second legs for providing resistance. The resistance is produced when the second end of the second leg is moved in a direction toward the first leg. A resilient spring is connected to the second leg. The resilient spring moves the second end of the second leg away from the first leg. A control valve is operatively connected to the cylinder for varying the resistance of the cylinder. A pad is positioned on the second end of the first leg. The pad is positioned to be engaged by the user to pivot the second end of the first leg towards said second leg against the resistance provided by the cylinder. The resilient spring moves the second end of the first leg away from the second leg to return the first leg to the original position. The user repetitively moves the second end of the first leg towards the second leg to exercise the lower extremity.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 273 words
An exercise device for the soleus muscle of the lower extremities to reduce deep vein thrombosis as a complication for both trauma and post-operative patients that can be mounted on a support comprising: a frame having a first leg and a second leg, said first and second legs each having a first end and a second end, said first end of said first and second legs being pivotally connected; a means for providing resistance being connected to the first and second legs, said resistance means having a cylinder with a movable piston positioned in the cylinder and a rod connected to the piston and extending from the cylinder, the cylinder being connected to said second leg of said frame and said rod being connected to said first leg, a discharge port positioned in said cylinder on the side of said piston that is opposite to the side of said piston where said rod is connected, whereby advancing said second end of said first leg towards said second leg causes said piston to move in said cylinder and to discharge fluid from said discharge port to provide resistance to the movement of said second leg; a resilient member connected to said second leg, said resilient member acting to move said second end of said first leg away from said second leg; a control means for varying the resistance of said resistance means, said control means being a valve that is operatively connected to said discharge port, said valve controlling the effective opening of said discharge port to control the resistance provided by said resistance means; and, means for mounting said frame to a support.
Claim 2
Dependent Claim 273 words
An exercise device for the soleus muscle of the lower extremities to reduce deep vein thrombosis as a complication for both trauma and post-operative patients that can be mounted on a support comprising: a frame having a first leg and a second leg, said first and second legs each having a first end and a second end, said first end of said first and second legs being pivotally connected; a means for providing resistance being connected to the first and second legs, said resistance means having a cylinder with a movable piston positioned in the cylinder and a rod connected to the piston and extending from the cylinder, the cylinder being connected to said second leg of said frame and said rod being connected to said first leg, a discharge port positioned in said cylinder on the side of said piston that is opposite to the side of said piston where said rod is connected, whereby advancing said second end of said first leg towards said second leg causes said piston to move in said cylinder and to discharge fluid from said discharge port to provide resistance to the movement of said second leg; a resilient member connected to said second leg, said resilient member acting to move said second end of said first leg away from said second leg; a control means for varying the resistance of said resistance means, said control means being a valve that is operatively connected to said discharge port, said valve controlling the effective opening of said discharge port to control the resistance provided by said resistance means; and, means for mounting said frame to a support.
Claim 3
Dependent Claim 26 words
The device of claim 1, wherein said first and second legs are each comprised of two spaced apart bars that are positioned in opposed parallel relationship.
Claim 4
Dependent Claim 27 words
The device of claim 2, wherein a pin passes through said first end of said first and second legs to pivotally connect said first and second legs.
Claim 5
Dependent Claim 32 words
The device of claim 3, wherein said resilient member is a spring that acts upon said first leg to urge said second end of said first leg away from said second leg.
Claim 6
Dependent Claim 27 words
The device of claim 4, wherein said spring is a coil spring placed on said pin, said end of said spring extending and engaging said first leg.
Claim 7
Dependent Claim 47 words
The device of claim 1, wherein said second leg is securely connected to a support bracket whereby said second end of said first leg can be advanced toward said second leg by the lower extremity of the user to maintain the desired circulation in the lower extremity.
