DIVING BARRIER Filed Oct. 19, 1960 2 Sheets-Sheet 2 United States Patent 3,096,980 DIVING BARRIER Walter W. Gauer, Kenilworth, N.J., assignor to Wroble & Gauer Co., Inc., Kenilworth, N.J., a corporation of New Jersey Filed Oct. 19, 1960, Ser. No. 63,527 Claims. (Cl. 27266) This invention relates to a diving barrier for teaching beginning swimmers the fundamentals of diving into water.

When beginners are learning to dive into water from the side of a pool or from a diving board the normal tendency is to attempt to maintain the head high when entering the water with the hope that the head will not become submerged upon entering the water. This head [high posiiton of a dive results in the beginner executing an extremely shallow dive with the stomach striking the water first. This type of dive is of course painful in some instances :as the diver does not cut the water smoothly and cleanly.

In order to assure that a beginner will not execute an extremely shallow dive of this type, instructors often make use of horizontal barriers positioned a spaced distance above the surface from which the beginner is diving which requires that the knees and feet of a diver be elevated above the barrier in order to clear the same. With the knees and feet of the diver being required to pass over such a horizontal barrier, the diver is forced to enter the water in a head downward inclined position thereby eliminating any possibility of the diver executing an extremely shallow dive.

Instructors have heretofore made use of hurdle-like barriers similar to those used in track events for the pur pose of providing a barrier over which a diver must pass. These hurdle-like barriers are often heavy and cumbersome and are therefore not extremely desirable.

The main object of this invention is to provide a lightweight barrier which may be readily supported on a planar surface such as the apron of a pool or which may be clamped to the end of a diving board from which a beginner is learning to dive.

A further object of this invention, in accordance with the immediately preceding object, is to provide a diving barrier which may be readily adjusted in height and which is constructed in a manner whereby the diving barrier may be releasably retained in an operational position so that it will yield under contact by a diver should he not elevate his knees and feet high enough in order to clear the barrier.

A further object of this invention is to provide a diving barrier including an elevated horizontally disposed portion over which the diver must dive which may be positioned outwardly over the water in order to assure that the diver will also have to dive outwardly away from the supporting surface from which he is diving.

A final object to be specifically enumerated herein is to provide a diving barrier which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that be economically feasible, long lasting and relatively trouble free in operation.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being bad to the accompanyiing drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of the diving barrier shown mounted on the free end of a diving board and the "ice 2 horizontal portion of the diving barrier positioned outwardly beyond the end of the diving board;

FIGURE 2 is :an end elevational view of the diving barrier, parts thereof being broken away;

FIGURE 3 is a top plan view of the diving barrier seen in FIGURE 2 with the outline of a diving board being shown in phantom lines;

FIGURE 4 is a fragmentary side elevational view of the diving barrier showing the manner in which the U- shaped frame of the barrier may be adjusted in positions relative to the supporting arms of the barrier; and

FIGURE 5 is a transverse vertical sectional view taken substantially upon the plane indicated by the section line 55 of FIGURE 4 and showing further structural details of the manner in which the U-shaped frame of the diving barrier may be adjusted in various inclined positions relative to the supporting arms of the barrier.

Referring now more specifically to the drawings, the numeral 10 generally designated the diving of the instant invention which is shown in FIGURE 1 of the drawings clamped to a conventional diving or spring board 12. A diver 14 is shown in position diving over the barrier 10 in FIGURE 1 and it will be noted that the knees 16 and feet 18 of the diver 14 are required to clear the barrier 10 in order for the diver 14 to enter the water.

With attention now directed to FIGURE 2 of the drawings it will be seen that the diving barrier 10 includes a generally U-shaped frame referred to in general by the reference numeral 20. The frame 20 include a pair of generally parallel legs 22 which are interconnected at their outer ends by means of an integral bight portion 24. The high: portion 24 and the legs 22 are all contained substantially in the same plane and the free ends of the legs 22 are received in socket members 26 carried by the supporting arm assemblies generally referred to by the reference numeral 28. The socket members 26 are each provided with a blind bore 30 which receives the end of the corresponding leg 22 and each of the socket members 26 is provided with a transverse bore 32 in which there is threadedly engage-d a setscrew 34 by which the free ends of the legs 22 are secured within the blind bores 30. The supporting arm assemblies 28 each include a pair of

socket members

26 and 29. The end of each of the socket members 26 remote from the bore 30 is provided with a circular face 36 and a transverse bore 38 which is concentric with the circular face 36. The circular face 36 includes a serrated annular portion 40 and a center circular projection 42. One end of the socket member 29 is also provided with a circular race which is designated by the reference numeral 42 and a transverse bore 44 similar to bore 381. The circular face 42 includes an annular serrated surface 46 corresponding to and interlockingly engageabie with the annular surface 40 and a center circular recess 48 for receiving the projection 42. With the

socket members

26 and 29 positioned as illustrated in FIGURE 5 of the drawings a suitable threaded fastener 50 is secured through the alined bores 38 and 44 in order to retain the

socket members

26 and 29 in adjusted positions relative to each other.

The end of the socket member 29 remote from the bore 44 includes a diametrically reduced threaded shank portion 52 which may either be formed integrally with the socket member 29 or comprise a separate stud threadedly engaged in a threaded bore formed in the socket member 29. In the event the threaded shank 52 comprises a part of a stud, a locking nut 54 is threadedly engaged with the shank 52 and abuts the outer end of the socket member 29 and serves as a jamnut for preventing rotation of the of the stud relative to the socket member 29. A clamp assembly which can best be seen in FIGURES 2 and 3 of the drawings is generally designated by the reference numeral 56 and includes a pair of L-

shaped arms

58 and 60 which are each provided with angulated and opposing frame-like planar clamp heads generally referred to by the

reference numerals

62 and 64. The

clamp heads

62 and 64 are formed on one pair of corresponding ends of the L-shaped arms 58 and 60' and an integral resilient coil 66 interconnects the other corresponding ends of the L-

shaped arms

58 and 60 and resiliently urges the

clamp heads

62 and 64 toward tight frictional engagement with each other.

' Each of the clamp heads includes a generally rectangular framework which may be covered by a suitable type of resilient material such as rubber hose 66.

The coil 66 slidably and rotatably receives the stud 52 and a retaining nut 68 is threadedly engaged with the outer free end portion of the stud 52 in order to retain the clamp 56 on its associated stud 52 and also to afford a means whereby the clamp members 56 may be frictionally retained in adjusted rotated positions about the longitudinal axis of the studs 52.

In operation, the clamp members 56 may be utilized to secure the dividing barrier to the free end of the diving board 12 as illustrated in FIGURE 1 of the drawing and the U-shaped frame may be adjusted in inclination relative to the longitudinal axis of the socket members 29 by loosening the fasteners 50 and adjusting the frame 20 to the desired position and then retightening the fasteners 50.

If it is desired the clamp members 56 may also be utilized to engage the top of a diving stool by which the elevation of the diver above the water may be increased in case he is diving from the apron of a pool and also it is to be noted that the socket members 29 of the supporting arm assemblies 28 could be disposed in overlying relation to the apron of a pool and blocks for sandbags and the like utilized to maintain the diving barrier 10 in adjusted operational positions along the side of a pool.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes Will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the Scope of the invention as claimed.
