Device for securing a shade to a light fixture

A device configured for use with a lighting fixture, the device comprising:

• a bolt with a head and a shaft, the shaft having a first set of threads that face radially outwards, the head being substantially spherical, the first set of threads structured to engage a second set of threads that are disposed on a finial;
• a seat ring having a third set of threads that are arranged radially inwards, the third set of threads structured to engage the first set of threads;
• and
• a mechanical coupling structured to attach the bolt to the lighting fixture, the mechanical coupling having a first opening, the mechanical coupling structured such that a longitudinal axis of the bolt can be tilted with respect to a longitudinal axis of the first opening while the bolt remains attached to the lighting fixture;
• the tensioning device structured to prevent the head of the bolt from contacting the mechanical coupling when the bolt is attached to the lighting fixture.

A device comprising:

• a bolt including a head and a shaft, the bolt having a first longitudinal axis passing through a center of the head and the shaft, the shaft having a first set of threads disposed on a radially outer surface of the shaft, the head having a substantially convex surface;
• a nut having a second set of threads disposed on a radially inner surface of the nut, the second set of threads structured to threadably engage the first set of threads;
• and
• a coupling structured to attach the bolt to an object, the coupling and the nut structured to maintain the substantially convex surface of the head in an abutting relationship with a substantially concave surface of the object;
• the coupling comprising a first opening having a second longitudinal axis passing through the center of the first opening, the first opening structured to surround the shaft of the bolt, the coupling and the bolt structured such that that the first longitudinal axis can be angularly displaced with respect to the second longitudinal axis when the shaft of the bolt is surrounded by the first opening.
