Abstract

A support pole for raising and lowering a supported object between a lower position and an elevated position is disclosed. The support pole includes an elongate pole having a top, a bottom, and a channel extending at least partly between the top and bottom. A threaded rod is rotationally mounted within the channel, and is connected to a detachable coupling for engaging a drive tool to rotationally drive the threaded rod. A carriage engages the threaded rod, such that rotation of the rod imparts translational movement upon the carriage through the channel. The carriage includes a mounting bracket for attachment of the supported object thereto. A cable connecting the supported object and an external device or power source has a detachable coupling, and is carried along a pulley at the top of the elongate pole when the carriage is raised and lowered. A return spring is connected to one end of the cable to retract the free end of the cable back to the base of the pole when the supported object is raised into the elevated position. Carriage locks at the top of the pole engage the carriage in the elevated position to prevent vibration of the supported object. A stabilizer frame within the channel minimizes vibration of the threaded rod as it is rotationally driven.

Claims

1. A support pole for supporting an object in an elevated position, comprising:

an elongate pole having a top and a bottom;

a carriage translationally mounted to said pole, said carriage comprising at least one carriage guide having a beveled, inclined surface facing toward the top of said pole; and

at least one carriage lock mounted to said pole, said carriage lock comprising a beveled, inclined surface facing toward the bottom of said pole for engagement with the beveled, inclined surface of said carriage guide.

2. A support pole for supporting an object in an elevated position, comprising:

an elongate pole having a top and a bottom, and a channel extending at least partly between said top and said bottom;

a threaded rod rotationally mounted within said channel, said rod being connected to a detachable coupling for engaging a drive tool;

a carriage in engagement with said threaded rod, at least a portion of said carriage extending outside of said channel, whereby rotation of said rod imparts translational movement upon said carriage through said channel; and

a stabilizer frame sliding within said channel, said stabilizer frame comprising;

upper and lower elements engaging said threaded rod and spaced at a distance from one another; and

at least one intermediate member connecting said upper and lower elements while allowing free movement of said carriage between said upper and lower elements.

3. A support pole for supporting an object in an elevated position, comprising:

an elongate pole having a top and a bottom, and a channel extending at least partly between said top and said bottom;

a threaded rod rotationally mounted within said channel, said rod being connected to a detachable coupling for engaging a drive tool;

a carriage in engagement with said threaded rod, at least a portion of said carriage extending outside of said channel, whereby rotation of said rod imparts translational movement upon said carriage through said channel; and

wherein said pole comprises at least one carriage lock adjacent the top for engagement with a cooperating portion of said carriage, each said carriage lock comprising a beveled, inclined surface.

4. The support pole of claim 3, wherein said carriage comprises a carriage guide portion disposed within said channel and further comprises a threaded bore for engaging said threaded rod, and wherein said carriage further comprises a mounting bracket external and adjacent said channel for attachment to a supported object.

5. The support pole of claim 4, wherein said pole comprises a gasket sealing an opening to said channel, between said channel and said mounting bracket.

6. The support pole of claim 3, further comprising a cable having a first end for connection to a supported object mounted to said carriage, a second end comprising a detachable coupling, and an intermediate section between said first and second ends.

7. The support pole of claim 6, further comprising a pulley mounted adjacent the top of said elongate pole, said pulley carrying the intermediate section of said cable.

8. The support pole of claim 7, further comprising a return spring connected to the second end of said cable.

9. A support pole for raising and lowering a supported object between a lower position and an elevated position, said support pole comprising:

an elongate pole having a top and a bottom, and a channel extending at least partly between said top and said bottom;

a carriage translationally mounted within said channel, at least a portion of said carriage extending outside of said channel; and

a drive mechanism for imparting translational movement of said carriage along said channel, wherein said drive mechanism is substantially housed within said elongate pole;

wherein said channel comprises first and second guide tracks, and said carriage comprises first and second carriage guides engaged within said first and second guide tracks respectively; and

wherein said pole comprises first and second carriage locks adjacent the top for engagement with cooperating portions of said carriage guides.

10. The support pole of claim 9, wherein said drive mechanism comprises a threaded rod rotationally mounted within said channel and engaged within a threaded bore through said carriage.

11. The support pole of claim 10, wherein said threaded rod is connected to a detachable coupling for engaging a drive tool.

12. The support pole of claim 9, wherein said pole comprises a gasket sealing an opening to said channel, and wherein said carriage comprises a mounting bracket external of said gasket for attachment to a supported object.

13. The support pole of claim 9, further comprising a cable having a first end for connection to a supported object mounted to said carriage, a second end comprising a detachable coupling, and an intermediate section between said first and second ends.

14. The support pole of claim 13, further comprising a pulley mounted adjacent the top of said elongate pole, said pulley carrying the intermediate section of said cable.

15. The support pole of claim 14, further comprising a return spring connected to the second end of said cable.

16. A support pole for raising and lowering a supported object between a lower position and an elevated position, said support pole comprising:

an elongate pole having a top and a bottom, and a channel extending at least partly between said top and said bottom;

a carriage translationally mounted within said channel, at least a portion of said carriage extending outside of said channel;

a drive mechanism for imparting translational movement of said carriage along said channel, wherein said drive mechanism is substantially housed within said elongate pole; and

a stabilizer frame sliding within said channel, said stabilizer frame comprising;

upper and lower elements engaging said drive mechanism and spaced at a distance from one another; and

at least one intermediate member connecting said upper and lower elements while allowing free movement of said carriage between said upper and lower elements.
