Abstract
An exercise and stretching device has a line and a combination comprising a support positioned relative to the line to redirect the line from a first direction to a second direction. The line has a first location on one side of the support to secure a first human appendage and a second location on an other side of the support for manipulation by a different human appendage. A grip is positioned relative to the support to hold the line at a selected position relative to the support.
Claims4
In a stretching device for an appendage of a human user, which device is adapted for use by said user in a variety of orientations, the combination comprising:
- A. a line having loop at first location on one side of a support to secure a human leg appendage to said line by way of a user's foot, and a second location on another side of said support having a handle for manipulation by a user while the user's appendage is secured at said first location;
- B. a support having opposed ends and:
- i. redirecting means adjacent one of said ends for redirecting said line from a first direction to a second direction;
- and
- ii. an anchor connector adjacent the end of said support opposite the end having said redirecting means, said anchor connector having adjacent the opposed end either a female cavity connector component or a male protrusion connector component having a plurality of male sides that mate with corresponding female sides within said cavity in any one of a plurality of different orientations of said connectors relative to one another;
- C. an anchor for securing said support to a fixture, said anchor being configured to be easily separable by said human user from said support and having opposed ends and:
- i. a clamp adjacent one of said ends for securance of said anchor to a fixture;
- and
- ii. a support connector adjacent said other opposed end, defining the one of said female and male components not defined by said anchor connector, said male and female components having holes extending therethrough which register when said sides of said components mate in any of said different orientations;
- D. means extendable through registering holes in said components for securing said support and said anchor together at different relative orientations;
- and
- E. a grip positioned relative to said support to selectively prevent said line from moving lengthwise during said stretching toward said first location, said grip including a cam cleat having opposing spring loaded cams to engage said line and prevent its movement lengthwise toward said first location.

In a stretching device for a leg hamstring muscle of a human user, which device is adapted for use by said user in a variety of orientations, the combination comprising:
- A. a line having a loop at a first location one side of said support to secure a human leg appendage to said line by way of a user'foot, and a second location on another side of said support having a handle for manipulation by a user while the user's appendage is secured at said first location;
- B. a support having:
- i. a pulley for redirecting said line from a first direction to a second direction;
- and
- ii. an anchor connector adjacent the end of said support opposite the end having said pulley, said anchor connector having adjacent the opposed end either a female cavity connector component or a male protrusion connector component having a plurality of male sides that mate with corresponding female sides within said cavity in any one of a plurality of different orientations of said connectors relative to one another;
- C. an anchor connectable to said support for securing said support to a fixture, said anchor being easily separable by said human user from said support and having:
- i. a clamp adjacent one end for securance of said anchor to a fixture, said clamp including:
- a. a bracket for placement about an edge of said fixture;
- and
- b. a plate for bearing against said fixture to capture said fixture edge;
- and
- ii. a support connector adjacent an end of said anchor opposite said end having said clamp, said support connector defining the one of said female and male components not defined by said anchor connector of said support, said male and female components having holes extending therethrough which register when said sides of said components mate in any of said different orientations;
- D. a pin extendable through registering holes in said components for securing said support and said anchor together at a selected one of said different orientations;
- and
- E. a cam cleat having_opposed spring loaded, cams to engage said line and prevent its movement lengthwise toward said first location.
