Abstract
A simple drawer lock mechanism used in connection with a portable drafting table, combines in a unitary assembly a bolt, an actuating prong passing through an opening in the drawer face, and resilient biasing legs projecting from each side of the bolt. The actuating prong can be squeezed through the opening. The biasing legs can bear against the bottom of the drawer or be anchored to the back of the drawer face.
Claims15
A lock mechanism mountable against a substantially flat section of a cover, drawer, door, or door-jamb, said section having a front face, which comprises:
- a bolt mounted against said section;
- a pair of resiliently flexible prongs spaced apart and extending orthogonally from a front side of the bolt through an aperture in said section,
- said prongs sized and dimensioned to pass through said aperture when said prongs are compressed toward each other,
- each of said flexible prongs having a nib, integral with said prong, projecting against said front face of said section beyond the periphery of said aperture in a rest state, thereby preventing movement of said bolt away from said section;
- and
- means for biasing the bolt in one axial direction.
A lock mechanism mountable against a substantially flat section of a cover, drawer, door, or door-jamb having a front face which comprises:
- a bolt mounted against said section;
- a plurality of resiliently flexible prongs extending orthogonally from a front side of the bolt through an aperture in said section,
- each of said flexible prongs having a nib, integral with said prong, projecting against said front face of said section beyond the periphery of said aperture;
- means for biasing the bolt in one axial direction;
- and
- means for modifying the resiliency of said flexible prongs.

A lock mechanism mountable against a substantially flat section of a cover, drawer, door, or door-jamb, having a front face and an aperture which comprises:
- a bolt having a front side;
- means for biasing the bolt in one axial direction;
- means for mounting said bolt to said section consisting of:
- a pair of resiliently flexible prongs spaced apart and extending orthogonally from said front side of said bolt, sized and dimensioned to insert through said aperture when compressed;
- each of said prongs having a nib projecting against said front face of said section beyond the periphery of said aperture when said prongs are uncompressed and inserted.
