Abstract
A pelvic clamp for back stretching is disclosed which provides temporary relief for low back pain by employing means for stretching the lumbar region. Embodiments which provide this means for stretching include a cam stop assembly, a block stop assembly, a slide panel assembly and a bend rod assembly. Each of these assemblies works by squeezing the sides of the pelvic region in order to hold it stationary while the user exerts pressure on assembly elements to force the upper torso away from the pelvic region.
Claims6
A portable light-weight user-operated apparatus useful for relieving back pain by engaging the soft tissue between a pelvis and a top of a femur on each side of a user for stretching the lumbar region by holding stationary a pelvic region of the user comprising:
- A base configured to receive said user thereon in a supine position;
- and
- A pair of opposing mount assemblies affixed to the base in position to receive said user there between, each mount assembly of said pair of mount assemblies comprised of a mount having a first pivot hole and a second pivot hole disposed therein, a squeeze panel having squeeze panel adjustment holes disposed therein and a cam lever having a cam hole disposed therein, a first connecting pivot rod inserted into one of said squeeze panel adjustment holes and said first pivot hole, and a second connecting pivot rod into said cam hole and said second pivot hole parallel to said first connecting pivot rod and spaced therefrom such that rotation of said cam lever about said second connecting pivot rod in each of said pair of mount assemblies by the hands of a user urges each cam lever against the squeeze panel of each of said pair of mount assemblies causing said squeeze panel to pivot about said first connecting pivot rod and engage the soft tissue between the pelvis and a top of a femur on one side of a user thereby holding stationary said pelvic region as said user applies force through his arms and shoulders towards said pelvic region.

- A base configured to receive said user thereon in a supine position;
- and
- A pair of opposing mount assemblies affixed to the base in position to receive said user there between, each mount assembly of said pair of mount assemblies comprised of a squeeze panel and a cam lever, a first connecting pivot rod to which said squeeze panel is pivotally connected for rotation about said first connecting pivot rod and a second connecting pivot rod to which said cam lever is pivotally mounted for rotation about said second connecting pivot rod and extending parallel to said first connecting pivot rod and spaced therefrom such that rotation of said cam lever about said second connecting pivot rod in each of said pair of mount assemblies by the hands of a user urges each cam lever against the squeeze panel of each of said pair of mount assemblies causing said squeeze panel to pivot about said first connecting pivot rod and engage the soft tissue between the pelvis and a top of a femur on one side of a user thereby holding stationary said pelvic region as said user applies force through his arms and shoulders toward said pelvic region.
A user-operated apparatus useful for relieving back pain by engaging the soft tissue between a pelvis and a top of a femur on each side of a user for stretching the lumbar region by holding stationary a pelvic region of the user comprising:
- A base configured to receive said user thereon in a supine position;
- A pair of opposing squeeze panels each mounted for rotation about an associated axis substantially perpendicular to said base;
- A pair of cam levers each abutting one of said pair of opposing squeeze panels and mounted for rotation about an axis offset from and parallel to each said associated axis such that movement of said cam levers responsive to manual urging of a user rotates said squeeze panels about said associated axis into engagement with the soft tissue between a pelvis and a top of a femur on each side of said user thereby holding stationary a pelvic region of the user as the user stretches his lumbar region by pressing on said cam levers.
