Claims23
An apparatus for adjusting the elevation of one or more support structures for material comprising:
- a chair having an upper end and a lower end, wherein the upper end includes a receptacle configured to support at least one support structure;
- one or more vertical adjustment mechanisms configured to engage the receptacle of the chair to space the at least one support structure vertically away from the receptacle of the chair to vary the elevation of the at least one support structure relative to the lower end of the chair;
- and
- wherein the one or more vertical adjustment mechanisms is positionable between an engaged configuration between the receptacle of the chair and the at least one support structure and a disengaged configuration no longer between the receptacle of the chair and the at least one support structure, and wherein when in the engaged configuration the one or more vertical adjustment mechanisms is adapted to position the at least one support structure at a higher elevation than when in the disengaged configuration.
An apparatus for adjusting the elevation of one or more support structures for material comprising:
- a chair having an upper end and a lower end, and wherein the upper end includes a receptacle configured to support one or more support structures;
- one or more spacers having an upper end and a lower end, wherein the upper end of the one or more spacers includes a receptacle configured to engage one or more support structures and the lower end of the one or more spacers are configured to engage the receptacle of the chair to space the one or more support structures in the receptacle of the one or more spaces vertically away from the upper end of the chair to vary an elevation of the one or more support structures relative to the lower end of the chair;
- and
- wherein the chair positions the one or more support structures in at least one first elevation without the spacer engaged thereto and the one or more spacers when engaged to the chair positions the one or more support structures in at least one second elevation higher than the at least one first elevation.
A method of vertically adjusting the elevation of one or more support structures for material comprising:
- providing one or more support structures;
- providing one or more chairs configured to position the one or more support structures in at least one first elevation;
- engaging one or more spacers to the one or more chairs to position the one or more support structures in at least one second elevation that is higher in elevation than the at least one first elevation;
- engaging one or more support structures to the one or more spacers;
- and
- wherein the one or more chairs includes a receptacle configured to position the one or more support structures in the at least one first elevation, and further comprising rotating the one or more spacers relative to the one or more support structures and/or the receptacle of the one or more chairs.
