Abstract
Abstract A tent stake is provided which may be advantageously molded integrally from plastic and which has good strength yet relatively small cross sectional area. The stake includes an elongated body formed by three longitudinally extending ribs which are spaced about 120* apart to provide a generally Y-shaped cross section. The ribs taper at one end of the body to form a ground-entering end, and the driving end of the stake terminates in a generally convex head. A hook is formed on one of the longitudinally extending ribs and extends angularly outwardly from the head toward the ground-entering end of the stake. If desired, a second hook spaced longitudinally from the first hook may be provided on the same longitudinally extending rib. The longitudinally extending rib from which the hook extends is strengthened by an outer end portion which extends perpendicularly to the outwardly extending portion of the rib, and the driving portion of the stake may be reinforced by reinforcing ribs which extend between the head and the longitudinally extending ribs.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
243 words
A tent stake comprising an elongated body having a driving end and a ground-entering end, the body including three longitudinally extending ribs extending outwardly from the longitudinal axis of the body portion to provide the body with a generally Y-shaped cross section, the longitudinally extending ribs tapering toward the longitudinal axis adjacent the groundentering end to provide a relatively pointed ground-entering end, a head on the driving end of the body extending generally perpendicularly to the longitudinal axis of the body and having a greater cross sectional area than the cross sectional area of the body, the head having a generally arcuate top surface curving toward the ground-entering end of the body, one of the longitudinally extending ribs including a generally planar first portion extending outwardly from the longitudinal axis of the body and a second portion extending generally perpendicularly to the first portion at the outer end thereof to provide said one longitudinally extending rib with a generally T-shaped transverse cross section, the second portion extending longitudinally from the driving end of the body and terminating short of the tapered portion of said one longitudinal rib, and a hook extending outwardly from said second portion of said one longitudinally extending rib, the hook including a side portion extending from the arcuate top surface of the head angularly outwardly and toward the ground-entering end and a holding portion extending from the side portion to said second portion of said one longitudinally extending rib.
Claim 2
Dependent Claim
243 words
A tent stake comprising an elongated body having a driving end and a ground-entering end, the body including three longitudinally extending ribs extending outwardly from the longitudinal axis of the body portion to provide the body with a generally Y-shaped cross section, the longitudinally extending ribs tapering toward the longitudinal axis adjacent the groundentering end to provide a relatively pointed ground-entering end, a head on the driving end of the body extending generally perpendicularly to the longitudinal axis of the body and having a greater cross sectional area than the cross sectional area of the body, the head having a generally arcuate top surface curving toward the ground-entering end of the body, one of the longitudinally extending ribs including a generally planar first portion extending outwardly from the longitudinal axis of the body and a second portion extending generally perpendicularly to the first portion at the outer end thereof to provide said one longitudinally extending rib with a generally T-shaped transverse cross section, the second portion extending longitudinally from the driving end of the body and terminating short of the tapered portion of said one longitudinal rib, and a hook extending outwardly from said second portion of said one longitudinally extending rib, the hook including a side portion extending from the arcuate top surface of the head angularly outwardly and toward the ground-entering end and a holding portion extending from the side portion to said second portion of said one longitudinally extending rib.
Claim 3
Dependent Claim
68 words
The tent stake of claim 1 including a second hook spaced longitudinally from the first hook toward the ground-entering end of the body and extending outwardly from said second portion of said one longitudinally extending rib, the second hook including a side portion extending from said second portion angularly outwardly and toward the ground-entering end and a holding portion extending from the side portion toward said second portion.
Claim 4
Dependent Claim
40 words
The tent stake of claim 2 in which the distance which the second hook extends outwardly from said one longitudinally extending rib is no greater than the distance which the first hook extends outwardly from said one longitudinally extending rib.
Claim 5
Dependent Claim
60 words
The tent stake of claim 1 in which the arcuate surface of the head is generally convex and curves toward the ground-entering end of the body, the radius of curvature of the top surface in a plane parallel to said one longitudinally rib being greater than the radius of curvature in a plane perpendicular to said one longitudinally extending rib.
Claim 6
Dependent Claim
28 words
The tent stake of claim 1 in which the hook includes a central web portion having a thickness less than the thickness of the remainder of the hook.
Claim 7
Dependent Claim
23 words
The tent stake of claim 1 in which the holding portion of the hook extends arcuately toward the driving end of the body.
Claim 8
Dependent Claim
24 words
The tent stake of claim 1 in Which the longitudinally extending ribs are spaced about 120* apart around the longitudinal axis of the body.
Claim 9
Dependent Claim
71 words
The tent stake of claim 1 including a pair of reinforcing ribs on opposite sides of said one longitudinally extending rib extending between the head and said one longitudinally extending rib and a third reinforcing rib between the other two longitudinally extending ribs extending between the head and the other two longitudinally extending ribs, the reinforcing ribs extending from the head angularly inwardly and toward the ground-entering end of the body.
Claim 10
Dependent Claim
53 words
The tent stake of claim 8 in which the head has a generally triangular outer periphery which extends between the outer ends of adjacent longitudinally extending ribs and the reinforcing ribs are generally triangular and extend angularly inwardly toward the longitudinal axis of the body from adjacent the outer periphery of the head.
