Selectively movable foot model with cords
View Patent ↗A foot model having a plurality of segments representing the bones of a human foot. The segments are held together through a series of elastic cords. A portion of the segments contain hollow portions and/or tunnels which the elastic cords are placed in and through. The cords and segments form a first position of the foot model which demonstrates a normal human foot. The cords can be manipulated by pulling and other forces to arrange the segments in a second position. The second position demonstrates a foot ailment or condition such as club foot. The model can be manipulated to regain the first position and any position in between the first and second position.
1. A model of a foot comprising:
a series of segments;
a plurality of cords;
the plurality of cords comprising a first cord and a second cord
the segments representing bones of a foot;
at least two of the segments having an internal tunnel;
at least a portion of the segments held together by the plurality of cords;
the first cord forming a pattern through the segments wherein the cord exits the internal tunnel of a first segment and enters the internal tunnel of a second segment;
the second segment non-adjacent the first segment;
the first cord and the second cord having a horizontal portion and a vertical portion;
the first cord and the second cord having a portion between horizontal and vertical;
the model movable by manipulation of the plurality of cords to move from a first position to a second position;
a resistance on the plurality of cords provided by the segments maintains the model in either the first position or the second position until the plurality of cords are manipulated by a user of the model.
2. The invention of claim 1 , wherein:
the foot is a human foot.
3. The invention of claim 2 , wherein:
the first cord and the second cord each have a first end and a second end;
the ends are knotted to maintain the first cord and the second cord in the tunnels.
4. The invention of claim 3 , wherein:
the at least one cord is elastic.
5. The invention of claim 4 , wherein:
the segments are made from a plastic.
6. The invention of claim 5 , wherein:
at least one cord is pulled by a user of the model to selectively move a portion of the segments from the first position to the second position;
the segments maintain the second position until the at least one cord is again manipulated to selectively move the segments from the second position to the first position.
7. A model of a foot, comprising:
a series of segments;
a plurality of cords;
the plurality of cords comprising a first cord and a second cord;
the segments representing bones of a foot;
wherein one of the segments represents a tibia;
wherein one of the segments represents a fibula;
wherein one of the segments represents a metatarsal;
at least two of the segments having an internal tunnel;
at least a portion of the segments held together by the first cord of the plurality of cords;
the first cord forming a pattern through the segments wherein the first cord exits the internal tunnel of a first segment and enters the internal tunnel of a second segment;
the first cord horizontal between the segments representing the tibia and the fibula;
the first cord vertical between an upper portion of the fibula and a lower portion of the fibula;
the first cord spans to a posterior edge of the metatarsal in a vector between horizontal and vertical;
the second cord having a horizontal portion and a vertical portion;
the second cord having a portion between horizontal and vertical;
the model movable by manipulation of the plurality of cords to move from a first position to a second position;
a resistance on the plurality of cords provided by the segments maintains the model in either the first position or the second position until the plurality of cords are manipulated by a user of the model.
