Abstract
An adjustable support device can position a body such as a light fitting. This support device comprises an adjustable arm supported at a tilting point. The arm is connected on either side of the tilting point. A counterweight is attached to the arm through a holder. A mass in the holder is freely displacable such that the center of gravity of the support device lies beneath the tilting point in any position of the arm. The arm can be flexible and the holder can have an at least partially oval shape in longitudinal section. A concave part can be formed on the arm. This concave part can be engaged by a wheel on a stand in order to support the arm and body.
Claims19
An adjustable support device for a body, the support device comprising:
- a tilting point;
- an adjustable arm supported at the tilting point, at least a portion of the arm being made of flexible material and adapted to be attached to the body at a first end and a length of the arm extending from the tilting point to the first end thereof being a fixed length, the arm being movable about the tilting point;
- and a counterweight attached to a second end of the arm, the first and second ends of the arm being on opposite sides of the tilting point, the counterweight including at least one holder in which at least one mass is movably mounted, the at least one holder being attached to the arm and being movable therewith, the at least one mass being movable along a length of the at least one holder to be movable relative to the adjustable arm and to the at least one holder such that a center of gravity of the support device with the body and the tilting point lie on a generally vertical line in any position of the arm, wherein the holder in longitudinal section has at least a partially oval shape, a head of the oval shape being oriented outwardly.
The adjustable support device as claimed in 1, wherein the arm is bent at most in one direction.
The adjustable support device as claimed in 1, wherein the arm is generally straight.
A combination of an adjustable support device and a body, the support device comprising:
- a tilting point;
- an adjustable arm supported at a tilting point, at least a portion of the arm being made of a flexible material and being attached to the body at a first end, a length of the arm extending from the tilting point to the first end thereof being a fixed length;
- a counterweight operatively attached to a second end of the arm on, the first and second ends of the arm being on opposite sides of the tilting point;
- and
- at least one holder in which at least one mass is movably mounted, the holder being mounted on the arm and the holder in longitudinal section having a partially oval shape with a head of the oval shape of the holder being oriented outwardly, the at least one mass being movable along a length of the at least one holder such that a center of gravity of the support device with the body and the tilting point lie on a generally vertical line in any position of the arm.
