Abstract
A tree trunk guying system that permits the flow of vital tree-growing fluids along the cambium layer of the tree trunk and automatically detaches itself from the tree trunk after the tree becomes self-supporting makes use of a unique tree trunk-grasping collar featuring, first, a structure providing both adequate support for and minimal contact with the tree trunk and, second, means for disengaging the tree collar from the tree trunk after a predetermined period of time or predetermined expansion of the tree trunk.
Claims15
A collar capable of closure to a substantially circular form around a tree trunk, in the closed state comprising a strip having at least three inwardly projecting lugs, all of said lugs being substantially, uniformly spaced apart about said collar and being more yieldable than the tree trunk, said collar having means holding said strip in a closed state and for disengagement from said tree trunk by tree growth and concomitant tree trunk expansion.
In a tree guying system comprising a tree trunk encircling and grasping collar and means for anchoring said collar to an immovable surface to hold the tree in a fixed position, said collar comprising:
- a. an elongated strip having opposed ends formed into said collar to encircle the tree trunk;
- b. a plurality of yieldable lugs attached to the inner surface of said strip to abut the tree trunk and hold it in concentric spaced-apart relation thereto, said lugs having a smaller contact area with the tree trunk than with said collar to permit the flow of vital tree-growing fluids vertically along the tree trunk;
- and,
- c. means on said strip for disengaging said collar from said tree trunk that is actuated by tree growth and concomitant trunk expansion.
