Abstract: An adjustable collar apparatus and method to encircle a post or botanical item at its base, which collar apparatus comprises a plurality of at least three separate, identical, flat sheet panel elements. Each panel element has a generally arcuate, involute curved inner edge, a generally arcuate outer edge, a top and bottom surface, and first and second side edges, and is characterized by a dimple means positioned toward the first side edge and an elongated depressed area positioned toward the second side edge. The flat panel sheet elements are adjustably arranged in a side-edge, overlapping relationship, with the dimple means of one flat panel sheet element aligned with the elongated depressed area of an adjacent flat panel sheet element to form a collar apparatus about a post or the base of a botanical item. The dimple means is fastened in a snap-fit manner into the elongated depressed area by means of a blister edge formed at the bottom portion of the protruding area of the dimple and depressed area.

Abstract: An adjustable collar apparatus and method to encircle a post or botanical item at its base, which collar apparatus comprises a plurality of at least three separate, identical, and flat sheet panel elements. Each panel element has a generally arcuate, involute inner edge, a generally arcuate outer edge and first and second side edges, and is characterized by a first slotted opening positioned toward the first side edges and a second slotted opening positioned toward the second side edge. The flat panel sheet elements are arranged in a side-edge, overlapping relationship, with the first opening of one flat panel sheet element aligned with the second opening of an adjacent flat panel sheet element to form a collar apparatus about a post or the base of a botanical item. Fasteners are inserted between the aligned openings of adjacent flat panel sheet elements to permit slidable adjustment of the flat panel sheet elements and to retain the flat panel sheet elements together.

Abstract: A tree- or post-collar apparatus and method to form a protective area about the base of a tree or post, and which collar apparatus comprises a plurality of edge-overlapping, generally trapezoidal, flat panels having an inner and outer arcuate edge, to form an adjustable, inner, open circle about the tree or post, and fasteners extending through slotted openings, to permit the adjustment of the collar apparatus to the defined, open, inner diameter, and to secure the flat panels in the adjusted position.

Abstract: Eyeglass frames are disclosed in which the right and left lens rims are split to facilitate insertion and removal of lenses. A pair of flanges on each rim adjacent the split mate to form a composite lug which is received between upper and lower arms on the associated temple pieces whereby the rims are held in the closed position. Pivot pin means are provided to secure the temple pieces to the lugs on the lens rims. The lug and pivot pin arrangement is generally useful for securing removable temple pieces to lens rims.
