Light blocking apparatus and method of using same
An apparatus and method can be configured to adjustably block natural light and/or overhead lighting to provide a use desired amount of light within a particular work space. Embodiments can help permit a user to adjust the light affecting that user's work space so a common lighting arrangement affecting many different work spaces' within a common area (e.g. an office floor or large office room within a building, etc.) so that the illumination provided by one or more light sources to illuminate the common area can be adjusted to meet a particular user's preferences within a particular work space within that common work area.
1. A light blocking apparatus comprising:
a light blocking device having a screen, a light blocking device attachment mechanism, and an intermediate portion between the light blocking device attachment mechanism and the screen, the screen comprising a body configured to block sunlight;
the intermediate portion comprising a telescoping member that is extendable and retractable, the screen attached to a first end of the telescoping member via a screen attachment mechanism;
the light blocking device attachment mechanism attached to a second end of the telescoping member such that the intermediate portion is rotatable relative to the light blocking device attachment mechanism;
wherein the screen attachment mechanism comprises a first swivel mechanism and a second swivel mechanism, the screen rotatable in a first rotational direction about a first axis of rotation defined by the first swivel mechanism, the screen rotatable in a second rotational direction about a second axis of rotation defined by the second swivel mechanism, the second axis of rotation being perpendicular to the first axis of rotation;
the first swivel mechanism including a first swivel lock or swiveling force adjustment mechanism that is actuatable to adjust an amount of force needed to permit rotation of the screen in the first rotational direction, the first swivel lock or swiveling force adjustment mechanism including a set screw extending between inner and outer tubular elements positioned adjacent the first end of the telescoping member; and
the second swivel mechanism including a lock or force adjustment mechanism that is actuatable to adjust an amount of force needed to permit rotation of the screen in the second rotational direction, the lock or force adjustment mechanism of the second swivel mechanism including a rotatable element that is rotatable to adjust the amount of the force needed for rotation of the screen in the second rotational direction.
2. The light blocking apparatus of claim 1 , wherein the first axis of rotation of the first swivel mechanism is parallel to a length of the telescoping member and the second axis of rotation of the second swivel mechanism is transverse or perpendicular to the length of the telescoping member.
3. The light blocking apparatus of claim 2 , wherein the light blocking device attachment mechanism is configured so that the light blocking device is slideable along a structure when attached to the structure.
4. The light blocking apparatus of claim 3 , wherein the light blocking device attachment mechanism includes a body having a first jaw and a second jaw spaced apart from the first jaw to define a mouth for receiving at least a portion of the structure; and
wherein the light blocking device attachment mechanism also includes a ball joint or an axle about which the second end the telescoping member is rotatable such that the intermediate portion is rotatable relative to the light blocking device attachment mechanism.
5. The light blocking apparatus of claim 1 , wherein the light blocking device attachment mechanism is configured so that the light blocking device is slideable along a structure when attached to the structure.
6. The light blocking apparatus of claim 5 , wherein the light blocking device attachment mechanism includes a body having a first jaw and a second jaw spaced apart from the first jaw to define a mouth for receiving at least a portion of the structure.
7. The light blocking apparatus of claim 6 , wherein the first jaw is moveable relative to the second jaw to adjust a size of the mouth.
8. The light blocking apparatus of claim 6 , wherein the light blocking device attachment mechanism includes a ball joint or an axle about which the second end the telescoping member is rotatable such that the intermediate portion is rotatable relative to the light blocking device attachment mechanism.
9. The light blocking apparatus of claim 1 , wherein the light blocking device attachment mechanism includes a ball joint or an axle about which the second end the telescoping member is rotatable such that the intermediate portion is rotatable relative to the light blocking device attachment mechanism.
10. The light blocking apparatus of claim 1 , wherein the light blocking device attachment mechanism also includes a ball joint about which the second end the telescoping member is rotatable such that the intermediate portion is rotatable relative to the light blocking device attachment mechanism.
11. The light blocking apparatus of claim 10 , wherein the light blocking device attachment mechanism is configured so that the light blocking device is slideable along a structure when attached to the structure.
