The vertical strip restraining elements include an inner surface facing toward the hard surface elements for receiving substantially horizontal forces from the hard surface elements. Horizontal extension elements are provided which extend out from an outer surface of the vertical strip restraining elements in at least the lower region of the upright strip restraining elements for receiving vertical forces relative to the ground surface. Force converting elements are provided for converting the horizontal forces received by the vertical strip restraining elements into vertical forces against the horizontal extension elements, thereby restraining the hard surface elements in the boundary. Attaching elements are provided which permit a detachable mounting of at least one of the horizontal extension elements and the force converting elements to the vertical strip restraining elements. | InventorApplicationNo. 07/213303 filed on 06/29/1988US Classes:404/7, Curb404/8With rim or edge protectorField of Search404/2, DRAIN OR GUTTER404/3, With conduit support means404/7, Curb404/8, With rim or edge protector404/17, PAVEMENT404/34Modules or blocks (preformed)ExaminersPrimary: Massie, Jerome W.Assistant: Spahn, Gay Ann Attorney, Agent or FirmUS Patent References113007, 379401, 398630, 456995, 567173, 670001, 806563, 1349340, 1894395, 1961227, 3545128, 3676952, 4663883Lawn trimming deviceIssued on: 05/12/1987 Inventor: Hilliard , et al.
