THE PRIOR ART Problems have heretofore occurred during volleyball games in determining when the volleyball passes over the net out of bounds. In order to assist officials in this matter, Section 2.23 of the Official 1974 Rules of the United States Volleyball Association requires that a vertical antenna be mounted on the net at each sideline to extend vertically from the bottom of the net to a height of 2 /2 feet minimum and 3% feet maximum above the net. The rules require that the antenna shall be so positioned that the distance from the outside edge of the two inch tape on the net above the sidelines to the inside edge of the antenna is 8 /2 inches. Therefore, when the volleyball touches the antenna, the official may easily determine that the volleyball is out of bounds.
Previously developed devices have been utilized in an attempt to secure such antennas to the side of a volleyball net. Such devices have often utilized laces or the like to tie the supporting members to the net. However, such prior devices have not securely held the antenna and the antenna has often vibrated out of position. In addition, such previously developed support devices have also been somewhat difficult to attach to the net and have tended to slip relatively to the net such that the position of the antenna varies.
SUMMARY OF THE INVENTION In accordance with the present invention, clamps are provided to securely position a vertical antenna at the sidelines of a volleyball net. The present clamps maintain the antenna in the proper position at all times and securely attach the antenna to the net such that the vibration of the net does not tend to dislodge the antenna from its desired position.
In accordance with the invention, apparatus. is provided for supporting a vertical antenna at the sidelines of a volleyball net which include an upper clamp having a slot for receiving the upper edge portion of the volleyball net and further including an aperture for receiving the antenna. Structure on the upper clamp is operable to .securely grip the upper edge portion of the net within the slot. A lower clamp has a slot for receiving the lower edge of the net and further includes an aperture for receiving the lower end of the antenna. Structure on the lower clamp is provided to securely grip the lower edge of the net within the slot. The upper and lower clamps are vertically aligned and clamp to the net in order to securely support the antenna such that the antenna extends vertically above the net to mark the sidelines of the volleyball court.
In accordance with a more specific aspect of the invention, apparatus for attaching a vertical antenna to a volleyball net includes a body having a resilient clamp portion. A slit is formed within the resilient clamp portion for receiving an edge of the volleyball net. Structure is provided to deform the resilient clamp portion to securely clamp the body to the edge of the volleyball net. An aperture is formed in the body for receiving the vertical antenna.
DESCRIPTION OF THE DRAWINGS For a more complete understanding of the present invention and for further objects and advantages thereof, reference is now made to the following description taken in conjunction with the accompanying drawings, in which:
FIG. 1 is a view, partially broken away, of a volleyball net illustrating antennas supported by the present clamp devices;
FIG. 2 is a perspective view of one of the upper antenna supporting clamps according to the invention;
FIG. 3 is a side view of the upper clamp shown in FIG. 2;
FIG. 4 is a perspective view of one of the lower antenna supporting clamps according to the invention; and
FIG. 5 is a side view of the clamp shown in FIG. 4 when attached to the bottom portion of a net.
DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 illustrates a volleyball net generally illustrated by the numeral 10 and which is conventionally supported across the volleyball court by cables 12 and 14. Cable 12 runs through a double thickness canvas strip 16, while cable 14 is disposed through a canvas loop l8 or a canvas strip similar to 16. Net 10 is approximately 3 feet wide and 32 feet in length when stretched across the volleyball court. It is preferably made of 4 inch square mesh of linen twine and is rigged at the top ends and bottom to manilla rope in the conventional manner.
In accordance with Rule 2.23 of the 1974 Official Rules of the United States Volleyball Association, it is necessary to suspend 6 feet long antennas 20 and 22 at each sideline of the volleyball court such that the antennas extend to a height of 2% feet minimum and 3% feet maximum above the net 10. Antennas 20 and 22 must be positioned that the distance from the outside edge of the tapes 24 and 25 to the inside edges of the antennas 20 and 22 is 8% inches. Antennas 20 and 22 should not exceed inch in diameter and may be tapered with a minimum diameter at the top and are made of break-resistant material such as fiber glass or the like.
The above-noted Rule 2.23 requires that the antenna fastenings at the top and bottom of the net shall be such as to hold the antennas 20 and 22 securely and to allow adjustments for proper position. When the antennas 20 and 22 are properly positioned, if a volleyball passes between the antennas as illustrated by the dotted line position 26 without touching an antenna, the ball remains in play. However, if the ball touches one. of the antennas as shown by the dotted line position 27, the ball is considered out of bounds. In accordance with the present invention, upper antenna clamps 28 are attached to the top of the net 10 in order to support the antennas 20 and 22, while lower antenna clamps 30 are connected to the bottom of the net 10 in order to receive the bottom ends of the antennas 20 and 22.
FIGS. 2 and 3 illustrate the upper antenna clamps 28 in greater detail. The upper antenna clamp 28 is preferably made from an elastomeric material such as neoprene or the like. Clamp 28 comprises a rectangular body of elastomeric flexible material with a slot 32 formed across the lower end 34'of the rectangular body and extending upwardly to a generally cylindrical opening 36. Opening 36 is dimensioned to receive the cable 12 and the upper portion of the strip 16, as shown in FIGS. 2 and 3. A cylindrical aperture 38 is formed through the elastomeric body and is dimensioned to snugly receive the antenna 22 in order to allow upward and downward movement of the antenna 22 and to support the antenna 22 in the desired position.
A countersunk portion 40 is formed in one face of the elastomeric body and communicates with a cylindrical aperture 42 which extends to a second countersunk portion 44 in the other face of the elastomeric body. A bolt 46 is positioned with the bolt head in the countersunk portion 44 and extends through the aperture 42. A wing nut 48 is threaded on the end of the bolt 46 and is received within the countersunk portion 40.
In order to attach the upper clamps 28 to the net, the wing nut 48 is loosened and the bolt 46 is removed. Due to the flexible nature of the elastomeric body, the slot 32 may be opened to a sufficient extent to receive the cable 12 and the tape 16 as shown in FIGS. 2 and 3. The bolt 46 is then inserted through the aperture 42 and the wing nut 48 tightened to a sufficient extent such that the elastomeric body is deformed and the strip 16 is tightly gripped by the slot 32. The antenna 22 may then be adjusted vertically with respect to the upper clamp 28 to properly vertically position the antenna. As shown in FIG. 1, two of the upper clamps 28 are clamped to the top of the volleyball net on opposite sides thereof.
FIGS. 4 and 5 illustrate in detail one of the lower clamps 30. Clamps 30 are formed in a similar manner to the upper clamps, except that an aperture 50 extends only part way through the elastomeric rectangular clamp body 52. Aperture 50 is adapted to'receive the bottom end of the antenna 22 and to hold it securely and permanently without any slippage. A slot 54 is formed across the upper end of the rectangular body 52 and extends downwardly through the body to a cylindrical opening 56. As shown in FIG. 5, cylindrical opening 56 is dimensioned to receive the cable 14 and canvas loop 18 or a double thickness canvas strip similar to 16, with the lower portion of the net being received by the slot 54. A countersunk portion 58 is formed in one face of the body 50 and communicates through a circular aperture 60 with a countersunk portion 62. I
A bolt 64 is positioned through the circular apertures 60, with the head of the bolt 64 being received by the countersunk portion 62. A wing nut 66 is threadedly attached to the end of the bolt 64 and is received within the countersunk portion 58 as shown in FIG. 5.
In order to attach the lower clamps 30 to the volleyball net 10, the bolt 64 is removed and the body 52 is manually opened such that the slot 54 may receive the cable 14 and canvas loop 18 or double canvas strip similar to 16 as shown in FIG. 5. The bolt 64 is then in serted through the apertures 60 and the wing nut 66 tightened to deform the elastomeric body such that the clamp securely grips the bottom portion of the net. The lower end of the antenna 22 is titted into the aperture 50 such that the antenna is securely positioned.
Due to the flexible nature of the present clamps, the wing nuts 48 and 66 may be tightened such that the clamps very securely grip the volleyball net and are thus not easily dislodged due to vibration of the net. Due to the elastomeric nature of the present clamps, the clamps do not slip relative to the net and the positions of the antennas are constantly maintained in the desired truly vertical locations. The present clamps are easily installed and removed and are easily maintained.
Whereas the present invention has been described with respect to specific embodiments thereof, it will be understood that various changes and modifications will be suggested to one skilled in the art, and it is intended to encompass such changes and modifications as fall within the scope of the appended claims.
