Abstract

Some of the disclosed fixtures include a base defining a plane and an elongated arm having a first end that is pivotally coupled to the base via a hinge such that the arm is movable relative to the base between stowed and deployed positions in which the first end of the arm is substantially parallel and substantially perpendicular, respectively, to the plane, and a second end that is couplable to a light source. In some fixtures, movement of the arm to the deployed position moves or enables movement of the hinge to an engaged position in which the hinge prevents movement of the arm from the deployed position toward the stowed position via contacting hinge bearing surfaces. In some fixtures, only when the arm is in the deployed position, the hinge is in or movable to an engaged position that prevents movement of the arm from the deployed position.

Claims17

Dependent claims

A light fixture comprising:

a base including a bottom surface that lies in a plane;
and
an elongated arm having:
a first end that is pivotally coupled to the base via a hinge such that the arm is movable relative to the base between a stowed position in which the first end of the arm is substantially parallel to the plane and a deployed position in which the first end of the arm is substantially perpendicular to the plane;
and
a second end that is configured to be coupled to a light source;
wherein movement of the arm to the deployed position moves the hinge, or enables movement of the hinge:
to an engaged position in which the hinge prevents movement of the arm from the deployed position toward the stowed position via bearing surfaces of the hinge contacting one another;
and
from a disengaged position in which the bearing surfaces do not contact one another;
wherein the hinge comprises a linkage that is coupled between the base and the first end of the arm, the linkage including:
a first link having:
a first end pivotally coupled to the base;
and
a second end defining a first one of the bearing surfaces;
and
a second link having:
a first end pivotally coupled to the second end of the first link, the first end of the second link defining a second one of the bearing surfaces;
and
a second end pivotally coupled to the first end of the arm.

17 more elements

A method for positioning a light fixture, the method comprising:

moving an elongated arm of a light fixture having a first end that is pivotally coupled via a hinge to a base of the light fixture and a second end that is configured to be coupled to a light source:
from a stowed position in which the first end of the arm is substantially parallel to a plane defined by a bottom surface of the base;
and
to a deployed position in which the first end of the arm is substantially perpendicular to the plane;
and
moving the hinge to:
an engaged position in which the hinge prevents movement of the arm from the deployed position and toward the stowed position via bearing surfaces of the hinge contacting one another;
and
from a disengaged position in which the bearing surfaces do not contact one another;
wherein the hinge is only in or movable to the engaged position when the arm is in the deployed position;
wherein the hinge comprises a linkage that is coupled between the base and the first end of the arm, the linkage including:
a first link having:
a first end pivotally coupled to the base;
and
a second end defining a first one of the bearing surfaces;
and
a second link having:
a first end pivotally coupled to the second end of the first link, the first end of the second link defining a second one of the bearing surfaces;
and
a second end pivotally coupled to the first end of the arm.
