Projector adjustment mechanism
View Patent ↗In one example, a device for mounting and adjusting an electronic device is described. The device can include a mounting frame, an elongated shaft connected to the mounting frame, a curved arm for operatively connecting to an electronic device and slidably engaging with the shaft, and a threaded knob configured for threadable engagement with the curved arm.
1. A device for mounting and adjusting an electronic device, comprising:
a mounting frame;
a plurality of straight, tubular elongated shafts located symmetrically about an axis of the device, each of the plurality of the tubular elongated shafts fixedly attached to the mounting frame, each shaft having a longitudinal axis, each shaft comprising:
a distal end; and
a proximal end connected to the mounting frame;
a plurality of curved arms configured to mount to the electronic device, each arm including a distal end and a proximal end, the proximal end of each of the plurality of curved arms including a hollow cylinder configured to receive a least a portion of a corresponding shaft extending therethrough, the proximal end of each of the plurality of curved arms configured to slidably engage with an external surface of the corresponding tubular elongated shaft, the distal end of each of the plurality of curved arms operatively connectable to the electronic device, the proximal end of each of the plurality of curved arms having a threaded section, the distal end of each curved arm comprising an arcuate portion extending outward from an external surface of the hollow cylinder, the arcuate portion comprising an opening extending along a length thereof, each curved arm configured to receive at least a portion of a corresponding spacer, each curved arm configured to slidably engage with the corresponding tubular elongated shaft;
a plurality of threaded knobs, each knob comprising a distal end and a proximal end, the proximal end of each of the plurality of threaded knobs, having a threaded section configured for engagement with the threaded section of the corresponding curved arm, each knob positioned at the distal end of the corresponding tubular elongated shaft, and each knob configured to rotate about the longitudinal axis of the corresponding tubular elongated shaft,
wherein a rotation of one of the threaded knobs permits rotation of the corresponding curved arm about the longitudinal axis of the corresponding tubular elongated shaft, and wherein the rotation of the corresponding curved arm about the elongated axis of the corresponding tubular elongated shaft raises or lowers the portion of the electronic device attached thereto, and
wherein each of said threaded knob, hollow cylinder, and elongated shaft are axially aligned with respect to the longitudinal axis of the corresponding elongated shaft.
2. The device of claim 1 , wherein the opening of each arcuate portion is configured for passage of at least a portion of a fastening device extending therethrough for attaching the corresponding curved arm and at least a portion of the electronic device to each other.
3. The device of claim 2 , further comprising a washer adapted to receive the fastening device, wherein the washer has an arcuate profile adapted to remain in contact with the arcuate wall of the corresponding curved arm.
4. The device of claim 1 , wherein the spacer has a shape corresponding to at least a portion of a cone, the spacer configured to provide a frictional engagement between the corresponding tubular elongated shaft, tire corresponding curved arm and tire corresponding threaded knob.
5. The device of claim 1 , further comprising:
a plurality of spacers, wherein at least a portion of each of the plurality of the spacers received by a corresponding curved arm.
6. The device of claim 1 , wherein the plurality of tubular elongated shafts, curved arms, and threaded knobs include four tubular elongated shafts, correspondingly engaging with four curved arms, and four threaded knobs, each of the four tubular elongated shafts positioned symmetrically about an axis of the device.
7. The device of claim 6 , wherein each of the four curved arms is positionable along a length of the shaft at positions between the proximal and distal end of the shaft independent of the other of the four curved arms.
8. The device of claim 6 , wherein each of the four curved arms is rotationally positionable at positions about the shaft between 0 degrees and 360 degrees independently of the other of the four curved arms.
9. The device of claim 1 , wherein the electronic device is a projector configured to be mounted to a bottom of a generally horizontal surface.
10. The device of claim 9 , wherein the plurality of curved arms are adapted to connect to a top surface of the projector.
11. The device of claim 1 , wherein each of the curved arms frictionally engages with the corresponding tubular elongated shaft, the frictional engagement exclusively limiting slidable movement of the curved arm along a length of the tubular elongated shaft between the proximal and distal end of the tubular elongated shaft.
12. The device of claim 1 , wherein the threaded section on the curved arm is on an internal surface of the curved arm.
13. The device of claim 12 , wherein the threaded section on the threaded knob is on an external surface of the threaded knob.
