STAKE Filed Jan. 28, 1964 INVENTORS DON M-GLENDENNING OMER L. KINDIG SYMETRY ATTORNE Y5 United tates Patent l 3,230,329 STAKE Don M. Glendenning and Gmer L. Kindig, Huntington, Ind, assignors to The Locke Steel Chain Company, Huntington, End, a corporation of Connecticut Filed Jan. 28, 1964, Ser. No. 340,758 2 Claims. Il. 135--15) This invention relates to anchoring stakes and particularly to an improved ground stake for use as a tent or other type of stake.

The principal object of the invention is to provide a ground stake such as a tent stake that will be rugged in construction, simple in design and flush with the ground when used.

Another object of the invention is to provide a ground stake having a V-shaped cross sectional construction and a separate head member welded to one end of the stake.

Still another object of the invention is to provide such a stake in which the separate head includes a line engaging hook adapted to penetrate the ground when the stake is used.

Another object of the invention is to provide such a ground stake in which reinforcing means may be provided along the stake near its upper end and along the line engaging hook.

In one aspect of the invention, a shank of a ground stake may be formed from a length of flat sheet metal of sutiable gauge that is of a generally triangular shape. The flat sheet may be bent along its longitudinal centerline to form angularly disposed sides producing a V- shaped cross sectional construction.

In another aspect of the invention, indented longitudinally extending flutes, grooves or ribs may be formed along the angularly disposed sides.

In still another aspect of the invention, a head portion may be provided of much greater thickness than the gauge of the shank metal, and it may extend at right angles to the longitudinal centerline of the shank, and may be welded, or otherwise suitably fastened, to the end of the shank having the greatest cross sectional dimension.

In still another aspect of the invention, the extended end portion of the head may be bent toward the narrow end of the shank, and it may include an indented, longitudinally extending, reinforcing flute or groove.

The above, other objects and novel features of the invention will become apparent from the following specification and accompanying drawing which are merely exemplary.

In the drawing:

FIG. 1 is a perspective view of a tent stake in use and to which the principles of the invention have been applied;

FIG. 2 is an enlarged perspective view of the tent stake shown in FIG. 1;

FIG. 3 is a sectional view taken substantially along line 3-3 of FIG. 2;

FIG. 4 is a view of the stake minus its head;

FIG. 5 is a top plan view of the head of the stake;

FIG. 6 is an elevational view of the assembled stake and head of FIGS. 4 and 5; and

FIG. 7 is a piece of flat sheet metal stock from which the stake is formed.

Referring to the drawing, and particularly to FIG. 7, a shank 10 may be made from a piece of fiat plate of sheet metal stock of generally triangular configuration. The plate may include a semicircular notch 11 in its top edge 12, and separate flutes, grooves or ribs 13 of semicircular cross section extending longitudinally from the 3,280,829 Patented Oct. 25, 1966 top edge 12 and lying substantially parallel to the side edges of the shank 10.

Referring to FIGS. 2 and 3, the plate is bent along its longitudinal centerline so that the shank 10 assumes a V-shaped cross sectional form as shown in FIGS. 2 and 3 having tapering

sides

14 and 15.

Referring to FIG. 5, a head portion 16 may be made of a much heavier gauge of metal than the plate for shank 10, and it may include a triangular shape 17 adapted to lie over and cover the upper end of shank 10. An extension 18, from the apex of the triangularly shaped head portion 17, may have a reinforcing flute, groove or rib 19 formed therein of substantially semicircular cross section, and the extension 18 may be bent downwardly toward the tapered end of the stake.

Referring to FIG. 6, in assembling the head 16 to the upper end of shank 10, the outer periphery of the groove 19 in extension 18 is received within notch 11 so that head 16 rests fiat on the upper end of shank 10, and a welded joint 20 is shown as being provided between the head 16 and the top edge 12 of shank 10. The weld may be made by projection welding techniques but other forms of welding can be used.

Referring to FIG. 1, in use, the stake is driven into the ground so that the head 16 is flush with the ground, and the bent portion of extension 18 also is embedded in the ground so that anyone walking over the stake will not trip.

Although various features of the improved ground stake have been shown and described in detail to fully disclose one embodiment of the invention, it will be evident that changes may be made in such details and certain features may be used without others without departing from the principles of the invention.

What is claimed is:

1. A ground stake comprising a shank made from a triangularly shaped flat plate of stock of suitable gauge, said plate being bent along its longitudinal centerline to form said shank including two diverging sides angularly disposed relative to each other throughout their length; a fiat head of substantially thicker metal than and secured to said shank, said head having diverging sides and being of substantially the same shape and size as that end of said shank having the greatest dimension so as to lie substantially completely over and to conform to said end, said head including an extension bent from said flat head in a direction toward the opposite end of said shank, and elongated reinforcing ribs formed in and extending along said angular sides, said head affording a flat surface to receive driving blows.

2. In a ground stake according to claim 1, wherein the end of said shank having the greatest dimension has a portion of the stock removed therefrom to provide a supporting edge, and said extension on said flat head being adapted to be received in and supported by said supporting edge.
