Instrument and speaker lift stand
A musical instrument stand has an expandable telescoping stand with an adjustable travel stop included interior to an extension tube diameter. The telescopic extension of the musical instrument stand is adjustable by repositioning the travel stop longitudinally within the tube.
1. A lift mechanism for a tube, the lift mechanism comprising:
an adjustable travel stop having opposing surfaces defining lateral ends of the travel stop, the travel stop configured to be repositioned along a length of said tube such that the opposing surfaces are interior to the tube;
an extension mechanism configured to extend from said tube and pushing against said adjustable travel stop so as to thereby provide mechanical lift assistance,
wherein an extension limit of said lift mechanism is set by a position of said adjustable travel stop within said tube.
2. The lift mechanism for a tube according to claim 1 , further comprising a supporting base for said tube, wherein said supporting base comprises at least one leg that is independently adjustable to slide and secure on said tube.
3. The lift mechanism for a tube according to claim 1 , wherein said adjustable travel stop comprises: a retention mechanism having a split ring that is expandable to frictionally prevent motion of said adjustable travel stop within said tube.
4. The lift mechanism for a tube according to claim 1 , wherein said split ring is configured to expand outwardly to press against an inside diameter of said tube.
5. The lift mechanism for a tube according to claim 4 , wherein said expansion is actuated in response to a screw or bolt pushing a plurality of pins or balls outwardly against an inside diameter of the split ring.
6. The lift mechanism for a tube according to claim 1 , further comprising a supporting base for said tube, wherein said supporting base includes at least three legs secured on said tube.
7. The lift mechanism for a tube according to claim 1 , the lift mechanism further comprising: at least two arms that extend from a central head to engage a musical instrument.
8. The lift mechanism for a tube according to claim 1 , wherein said extension mechanism comprises: a spring or a gas filled strut.
9. The lift mechanism for a tube according to claim 1 , wherein said tube supports a musical instrument or a speaker.
