Combination stand and jack for wire spools
View Patent ↗A stand used for supporting spools of wire and the like includes a cam which is operable to increase the length of a leg to thereby raise the spool of wire off of the ground. The stand is adjustable to allow its use with different sizes of spools of wire. The stand allows a single person to raise a spool of wire weighing thousands of pounds off of the ground and support the same to allow the spool to rotate freely upon an axle.
1. A stand for use in lifting a spool, the stand comprising:
a base comprising a first end and a second end;
a holding mechanism configured for securing an axle, wherein the holding mechanism comprises a plurality of holes formed therein such that the holding mechanism may be selectively locked in one of a plurality of closed positions so as to accommodate axles of different sizes;
a first leg comprising:
a first end pivotably attached to the first end of the base,
a second end attached to the holding mechanism, and
a lifting mechanism that changes the length of the first leg for selectively raising and lowering the holding mechanism relative to the base; and
a second leg comprising a first end attached to the second end of the base and a second end pivotably attached to the holding mechanism.
2. The stand of claim 1 , wherein the second leg is telescopic to allow for adjustment of the length thereof.
3. The stand of claim 1 , wherein the holding mechanism is movable from an open position to a closed position and wherein the holding mechanism extends completely around the axle placed therein when the holding mechanism is in the closed position.
4. The stand of claim 1 , wherein the holding mechanism comprises a plurality of bearings disposed thereon such that the axle, when secured by the holding mechanism, only contacts the bearings.
5. The stand of claim 4 , wherein the plurality of bearings are positioned such that the plurality of bearings contact the axle, when secured by the holding mechanism, at two locations spaced apart laterally along the axle such that the plurality of bearings fix the orientation of the axle relative to the stand.
6. A stand configured for lifting and supporting a spool of wire, the stand comprising:
a base comprising a first end and a second end;
a holding mechanism configured for securing an axle, wherein the holding mechanism comprises a plurality of holes formed therein such that the holding mechanism may be selectively locked in one of a plurality of closed positions so as to accommodate axles of different sizes;
a first leg comprising:
a first end pivotably attached to the first end of the base, and
a second end attached to the holding mechanism; and
a second leg comprising a first end attached to the second end of the base and a second end pivotably attached to the holding mechanism,
wherein one of the first and second legs is selectively extendable and retractable so as to selectively raise the height of the holding mechanism relative to the base.
7. The stand of claim 6 , wherein one of the first and second legs is selectively extendible via a lifting mechanism and the other of the first and second legs is adjustable in length via a telescoping section and a locking member.
8. The stand of claim 6 , wherein the holding mechanism is movable from an open position to a closed position and wherein the holding mechanism extends completely around the axle placed therein when the holding mechanism is in the closed position.
9. The stand of claim 6 , wherein the holding mechanism comprises a plurality of bearings disposed thereon such that the holding mechanism, when secured by the stand, only contacts the bearings.
10. The stand of claim 9 , wherein the plurality of bearings are positioned such that the plurality of bearings contact the axle, when secured by the holding mechanism, at two locations spaced apart laterally along the axle such that the plurality of bearings fix the orientation of the axle relative to the stand.
11. A stand configured for lifting and supporting a spool of wire, the stand comprising:
a base;
a holding mechanism configured for securing an axle, wherein the holding mechanism comprises a plurality of holes formed therein such that the holding mechanism may be selectively locked in one of a plurality of closed positions so as to accommodate axles of different sizes; and
a first leg comprising:
an end attached to the holding mechanism, and
a lifting mechanism configured for selectively raising and lowering the holding mechanism relative to the base.
12. The stand of claim 11 , wherein the base comprises a first end and a second end, the stand further comprising a second leg comprising a first end attached to the second end of the base and a second end pivotably attached to the holding mechanism, wherein the second leg is selectively extendable and retractable so as to selectively raise the height of the holding mechanism relative to the base.
13. The stand of claim 12 , wherein the second leg comprises an outer member and an inner member which is telescopically movable within the outer member, and wherein the position of the inner member may be selectively fixed relative to the outer member.
14. The stand of claim 11 , wherein the first leg comprises an outer member and an inner member slidable within the outer member and wherein the lifting mechanism causes selective extension and retraction of the inner member relative to the outer member.
15. The stand of claim 11 , wherein the holding mechanism is movable from an open position to a closed position and wherein the holding mechanism extends completely around the axle placed therein when the holding mechanism is in the closed position.
16. The stand of claim 11 , wherein the holding mechanism comprises a plurality of bearings disposed thereon such that the axle, when secured by the holding mechanism, only contacts the bearings.
17. The stand of claim 16 , wherein the plurality of bearings are positioned such that the plurality of bearings contact the axle, when secured by the holding mechanism, at two locations spaced apart laterally along the axle such that the plurality of bearings fix the orientation of the axle relative to the stand.
