| 摘要 |
This invention consists of a tree grate system in concrete, artificial stone, terrazzo or similar molded material intended for use at ground level at the base of a tree. The system is designed to permit periodic enlargement of the opening for the tree trunk according to the growth of the tree. The system is formed by parallel or concentric grate elements forming a horizontal grill. Adjacent grate elements are joined by connectors which, when severed at their point of least section, permit the easy removal of the grate elements nearest the tree trunk, leaving a clean, presentable break at the remaining adjoining element.
