INVENTOR. JACK ZEDAKER ATTORNEY United States Patent 3,209,729 MAGNETIC HORSE JUMP STANDARD Jack Zedaker, 5715 Youngstown-Poland Road, Poland, Ohio Filed Apr. '16, 1963, Ser. No. 273,372 4 Claims. (Cl. 119-29) This invention relates to a horse jump standard of the type used for supporting poles over which horses are jumped.
The principal object of the invention is the provision of an improvement in a horse jump standard and more particularly in the hangers thereon by which the pole is supported.
A further object of the invention is the provision of a horse jump standard and a pole hanger therefor in which the hanger is adjustable over the effective vertical length of the standard.
A further object of the invention is the provision of a horse jum standard and a hanger therefor in which the hanger is adjustably positioned and secured to the hanger by magnetic means.
A still further object of the invention is the provision of a simple and inexpensive horse jump standard and pole hanger therefor which will provide ready separation of the standard and hanger in the event the horse hits the pole or the hanger.
The horse jump standard and magnetically attached pole hanger disclosed herein comprises an improvement in the art as heretofore known. It has been common to provide horse jump standards with various types of mechanical hangers secured thereto by various forms of fasteners and the like and which hangers could be moved vertically on the standards so as to support the actual jump pole at various heights relative to the base of the standard. Heretofore, such standards and hangers have had common objectionable characteristics in that the hangers while being adjustable on the standard were nevertheless secured thereto and frequently caused accidents by failure to readily dislodge or to release the pole or occasionally caused injury to the horse or rider when struck. These several objections are overcome by the present invention which provides a more or less conventional standard with a ferrous metal surface on one vertical side thereof and a hanger having a permanent magnet or magnets thereon by which it is secured to the ferrous metal surface of the standard. The hanger itself has a concave upper surface which supports the jump pole. The magnets are preferably Alnico, a permanent magnet material of unusual magnetic attraction and quite capable of holding the hanger and the pole in desired position on the structure. More importantly, it is adjusted vertically very easily by simply moving it or sliding it along the standard, and of equal importance is the fact that if it is struck accidentally by the horse or the rider it is readily released from the standard and thereby incapable of cansing injury.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being the intention to cover all changes and modifications of the example of the invention herein chosen for purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention.
The invention is illustrated in the accompanying drawing, wherein:
FIGURE 1 is a perspective view of a standard showing a hanger thereon and a portion of a pole illustrated in broken lines.
FIGURE 2 is an enlarged perspective view of the hanger seen in FIGURE 1.
FIGURE 3 is a front plan view of the hanger seen in FIGURE 1.
FIGURE 4 is a side view of the hanger seen in FIG- URE 1.
FIGURE 5 is a back view of the hanger seen in FIG- URE 1.
FIGURE 6 is a perspective view of an end portion of a jump pole showing a magnet embedded therein and which may be used as an alternate construction to the hanger shown and describedherein.
By referring to the drawings and FIGURE 1- in particular, it will be seen that a horse jump standard is disclosed which comprises a vertical post 10, a horizontally disposed first base member 11 and a transversely positioned second base member 12. An angular support bracket 13 is positioned between one end of the horizontal base member 11 and the-post 10 and a pair of oppositely disposed secondary angular support brackets 14 are positioned between the ends of the transverse base member 12 and the post 10. The construction of the post 10 and the supporting base is conventional in the art.
As illustrated in FIGURE 1 a strip 15 of ferrous metal such as steel is shown applied to one vertical surface of the post 10 and a hanger comprising a vertical body member 16 and a horizontal body member 17 having a permanent magnet or magnets afiixed thereto is mounted thereby on the ferrous metal strip 15. As shown, the horizontal body member 17 of the hanger is concave so that it will readily support one end of a pole as shown in broken lines and indicated by the numeral 18. Those skilled in the art will observe that in use a pair of the standards including the vertical poles 10, complete with the hangers, are used to support the pole 18 in horizontal relation. It will also occur to those skilled in the art that if desired the hanger may have the horizontal body portion 10 thereof modified to support the pole at right angles at the direction shown so that a pole of greater length than the distance between the standards may be employed.
By referring to FIGURES 2, 3, 4, and 5 of the drawings, detailed views of the hanger will be seen and it will be observed that the horizontal section 17 is positioned on the upper edge of the vertical body member 16 and supported in such position by a web 19.
By referring to FIGURES 4 and 5 of the drawings, it will be seen that a permanent magnet 20 is positioned on the :back of the vertical body member 16 with the outermost surface thereof in flush relation with the back edge portion of the horizontal member 17 which is illustrated as having a downturned flange 21. Those skilled in the art will observe that while one permanent magnet 20 has been illustrated several may be used if desired so that the hanger including the horizontal body member 17 on which the pole 18 rests will be adequately supported on the post 10.
In the event a pole 18 is longer than the spacing between the standards including the posts 10 the hanger and specifically the horizontal body member 17 thereof is modified by providing a sideward extension (not shown) so that the pole may be positioned alongside the post 10 and still supported on the horizontal body member 17.
It will thus be seen that when a pair of standards including the posts 10 are positioned in spaced relation and the hangers positioned thereon at a desired height they will readily support the jump pole 18. As the horse successfully completes each jump the hangers are moved vertically where the magnets 20 continue to hold them against the ferrous metal strip 15.
It will thus be seen that in the event a horse hits the pole 18 it will be readily dislodged and that in the event the horse .or the rider strikes the hanger it will readily be freed from the standard thereby avoiding injury. In such event, the hangers may readily be repositioned on the standards where they will again be held by magnetic attraction and the pole 18 is repositioned thereon. Those skilled in the art will observe that a reversal of parts makes possible a modification which is suitable under some circumstances and an illustration of the modification is found in FIGURE 6 wherein an end portion of a jump pole 22 is illustrated and shown with a permanent imagnet 23 embedded in the end thereof with the pole pieces of the magnet flush with the end 24 of the pole 22. Thus the pole with the magnet 23 therein may be self supporting on the standard shown in FIGURE 1 as the magnet 23 will engage the ferrous metal strip 15.
It Will thus be seen that a horse jump standard meeting the several objects of the invention has been disclosed and having thus described my invention, what I claim is:
1. A horse jump standard including a vertical post having an elongated ferrous metal strip on one side thereof and a hanger including a means for supporting a jump pole and including a vertical body member, said strip having a length several times the length of said body member, at least one permanent magnet secured to said vertical body member and engageable against the said ferrous metal strip for holding said hanger on said standard While supporting the jump pole.
2. The horse jump standard set forth in claim 1 wherein the hanger includes a horizontal member having a configuration for receiving and retaining said pole.
3. The horse jump standard set forth in claim 1 and wherein the hanger comprises an L-shaped body member having a web between the respective portions thereof.
4. A horse jump standard for supporting a jump pole, said standard having a vertical post, a strip of ferrous metal on said post, a jump pole, magnetic means in said jump pole engageable on said strip of ferrous metal for supporting said jump pole.
