Abstract
A frog for a stringed instrument bow is disclosed which has a hollow metal body, which may be made, for example, of direct laser metal sintered titanium. The hollow body has a top side adapted to engage a bow stick of the stringed instrument bow, and a bottom side adapted to support a hair bundle of the stringed instrument bow. A back stop is positioned proximate the bottom side in the interior of the hollow metal body and a cam attached to the bottom side of the hollow metal body is adapted to slide or rotate with respect to the hollow metal body, from an open position in which a hair bundle can be inserted in the hollow metal body and a closed position in which the cam forms a pinch point with the back stop to secure the hair bundle.

A frog for a stringed instrument bow, comprising:
- a hollow metal body having an interior and having a top side adapted to engage a bow stick of the stringed instrument bow, and a bottom side adapted to support a hair bundle of the stringed instrument bow;
- a back stop in a fixed position proximate the bottom side in the interior of the hollow metal body;
- a cam attached to the bottom side of the hollow metal body, adapted to slide or rotate with respect to the hollow metal body, from an open position in which a hair bundle can be inserted in the hollow metal body and a closed position in which the cam forms a pinch point with the back stop to secure a hair bundle;
- an underslide received over the cam in the closed position;
- and
- a ferrule and securing the underslide to the bottom side of the frog.
A frog for a stringed instrument bow, comprising:
- a hollow metal body having an interior and having a top side adapted to engage a bow stick of the stringed instrument bow, and a bottom side adapted to support a hair bundle of the stringed instrument bow;
- a back stop in a fixed position proximate the bottom side in the interior of the hollow metal body;
- a lever attached to a pivot point proximate the bottom side of the hollow metal body, adapted to rotate about the pivot point, from an open position in which one end of the lever is inside the hollow metal body and a closed position in which the lever is aligned with the bottom side of the hollow body and one end of the lever forms a pinch point with the back stop adapted to secure a hair bundle;
- an underslide received over the lever;
- and
- a ferrule received over the underslide.
A hair lock for a frog of a stringed instrument bow, the frog having an interior cavity, a top side adapted to engage a bow stick of the stringed instrument bow, and a bottom side adapted to support a hair bundle of the stringed instrument bow, the hair lock comprising:
- a back stop in the cavity of the frog, proximate a bottom side of the frog;
- a lever attached to the frog at a pivot point, proximate the bottom side of the frog, the lever being adapted to rotate about the pivot point, from an open position in which one end of the lever is inside the frog, and a closed position in which the lever is aligned with the bottom side of the frog and one end of the lever forms a pinch point with the back stop adapted to secure a hair bundle between the lever and the back stop, and
- further comprising an underslide covering the cavity and a ferrule clamping the underslide to the frog.
