Abstract

Abstract A stake for supporting weak-stemmed plants including, in one embodiment, an X-shape cross-sectional configuration wherein four orthogonally disposed arms, each having an arrowhead end, radiate outward from a common central vertical axis. A semi-annular clasp to retain a plant stem has reversed hook ends for snap-fit into the openings defined by the arrowheads on each side of the stake. In a second embodiment, the stake includes a central cylinder about which are disposed the arms, the cylinder serving to contain granular fertilizer for gradual dissolution into the earth around a supported plant.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 216 words
An agrarian stake comprising a straight four sided rod-like, ground engaging element of uniform X-shaped cross-section throughout the major part of its length, said element defining four orthogonally disposed and radially outwardly extending arms having their longitudinal outer edges equally radially spaced from the longitudinal axis of said element, the outer longitudinal edge of each arm having an arrowhead cross-section defining, on each side of said arm, a laterally protruding flange making a 45 degree angle with the associated arm, said arms defining between themselves four similar spaces opening at the four sides of said element, said flanges being co-planar, two by two, and each pair of co-planar flanges forming one side of said element and partially closing said space, and a clasp consisting of a band of resilient material formed into a semi-annular shape for encircling a plant stem, said band having an out turned hook at each end for snap fit removable attachment with any one of said pair of flanges by insertion within the associated space, whereby said clasp may be attached at any point longitudinally of said element and to any of its four sides and said clasp may slide along said element upon a force exerted on the same in a direction substantially parallel to the longitudinal axis of said element.
Claim 2
Dependent Claim 216 words
An agrarian stake comprising a straight four sided rod-like, ground engaging element of uniform X-shaped cross-section throughout the major part of its length, said element defining four orthogonally disposed and radially outwardly extending arms having their longitudinal outer edges equally radially spaced from the longitudinal axis of said element, the outer longitudinal edge of each arm having an arrowhead cross-section defining, on each side of said arm, a laterally protruding flange making a 45 degree angle with the associated arm, said arms defining between themselves four similar spaces opening at the four sides of said element, said flanges being co-planar, two by two, and each pair of co-planar flanges forming one side of said element and partially closing said space, and a clasp consisting of a band of resilient material formed into a semi-annular shape for encircling a plant stem, said band having an out turned hook at each end for snap fit removable attachment with any one of said pair of flanges by insertion within the associated space, whereby said clasp may be attached at any point longitudinally of said element and to any of its four sides and said clasp may slide along said element upon a force exerted on the same in a direction substantially parallel to the longitudinal axis of said element.
Claim 3
Dependent Claim 36 words
An agrarian stake as defined in claim 1 wherein said clasp is integrally formed with transversely extending ridges at its opposite outer sides whereby the clasp may be grasped between thumb and forefinger without slipping thereof.
