SHEET 3 [IF 3 TETHERED BALL APPARATUS This invention relates to amusement devices and in particular to a device of the kind including a captive impact element which may be struck with the hand or by a bat, racket or like implement.
This invention provides apparatus for playing a game comprising a tube at one end of which a co-axial bolt is attached and extending therebeyond, a nut threadedly mounted for movement on the said bolt, an impact element, and flexible means connected at one end to said impact element and its other end to the nut.
The impact element is preferably a hollow ball such as a tennis ball or the like.
The tube is normally provided with a means whereby it may be firmly mounted on the ground. Such means is perferably comprised by a pointed end which can be forced into the ground.
Alternatively the apparatus may further comprise a second tube attached to the free end of the bolt and means at the ends of the tubes to abut against closely spaced members such as the uprights of a door frame. In this arrangement there will normally be provided means for forcing the tubes apart so that the apparatus may be firmly jammedagainst these uprights.
The nut is desirably secured to the inside of a hollow tube by welding or similar means.
The flexible means may comprise a string, cord, twine or the like and preferably a nylon cord. The flexible means may be connected directly to the nut but preferably it is connected to one end of the lug which is attached to a tube which encloses the nut. One end of the lug may be welded on to the tube on its outer surface and the other end of the lug has a hole to which the flexible means is secured. A flanged ferrule is conveniently inserted into the hole in the lug to protect the cord where it is secured to the lug. The other end of the cord is preferably connected to an elongated member such as a wing nut which is pushed through the first of two holes in the ball. A flanged ferrule fits the bore of the wing nut and a second flanged ferrule protects the cord at the second hole in the ball. The flanges of the two ferrules bear one upon the other. The ferrules are preferably made of plastic or similar material having a low co-efficient of friction so that they can easily bear on each other.
The tube may be formed in two telescoping parts if it is desired that the distance of the bolt above the pointed end be varied.
The tube preferably has a flange above the point to limit the amount it is inserted into the ground. The flange preferably has two points to secure the tube in the ground and to prevent undue movement of the tube in the ground. The two tubes are preferably held together by a pin which may conveniently be in the form of a bolt pushed through a pair of holes in each. One of the holes in the outer tube may be large enough to allow the head of the bolt to pass through it and to butt against the registering hole in the inner tube.
Two holes are preferably formed in the ball by means of a hollow cylindrical drill at the opposite ends of the ball, the second hole being formed through the first hole substantially in alignment with the first hole into the wall of the ball against which a wooden or other similar base is placed. This ensures a clearly punched second hole. One end of the cord is inserted through both holes in the ball. A wing nut is secured to the end FIG. 2 is an enlarged detail of the device shown partially in section,
FIG. 3 is a section through the ball forming part of a device of the invention, and
FIG. 4 is a view similar to FIG. 2 of a modified device of the invention.
Referring now to the drawings, an amusement device FIG. 1 comprises a tube 2, an impact element 3 in the form of a hollow ball 3, a rotating cap member 4 and a cord 5 connecting the cap member 4 to the ball 3.
The tube 2 is in two parts 2a and 2b. The lower part 2a is pointed at its lower end 6 so that it can penetrate the ground and has a foot-plate 7 near this end to limit such penetration. Spikes 7a are formed on the footplate to grip the ground into which the pointed end 6 is forced. The upper part 212 is hollow and is telescopically received within the lower part 2a. A bolt 8 passes through aligned holes 9 in the two parts respectively to hold them in the desired relative position. The head 8a of bolt 8 passes through hole 9a and butts against the inner tube 2b to force the two tubes 7 together. The other end of the bolt 8 is secured by means of a wing nut 10. A nut 11 is welded into the upper end of the upper part 2b and has a bolt 12 received therein. A lock nut 13 fixes the position of the bolt 12 in the nut 11.
The rotating cap member 4 has an internal nut 4a which is in threaded engagement with the bolt 12. A head 12a is provided at the upper end of the bolt 11 to prevent the nut 40 riding off of the end of the bolt. The cap member also has a plastic closure 41) and a radially projecting lug 40. One end of the cord 5 is tied to the lug 4c by being passed through a hole therein. A plastic ferrule 4d lines the hole to protect the cord.
The other end of the cord passes through a hole 3a in the ball. This end of the cord is knotted. The cord 5 passes through a pair of facing flanged plastic ferrules l3 and 14. One ferrule 13 passes through a wing nut 15 forming a holding member while the other ferrule 14 lines the ball opening 3a. These flanged ferrules in the ball allow the ball to swivel thereby preventing the cord from twisting.
The hole 3a is formed by first punching a hole 3b at the opposite part of ball. The cord 5 passes through both holes and then receives the wing nut and ferrules. The wing nut is inclined and the wing nut and ferrules are drawn through the hole 3b. The first hole 3b in the ball may be ruptured by the insertion of the locking device without causing damage to the hole 3a retaining the locking device.
A game is played by mounting the tubes 2a and 2b in a vertical position and striking the ball 3 by bats, rackets or other devices. One player strikes the ball so that it moves in a clockwise direction and the other so that the ball moves in an anticlockwise direction. As the ball rotates in this manner, the cap member 4 rotates and the nut 4a moves axially along the bolt 12. Should one player fail to strike the ball when it approaches him the nut 4a will complete a revolution and will move axially.
When the nut has moved axially to one end of the bolt,
and stops the player whose action caused the nut to move in this direction is deemed to be the winner of the game.
The game begins when the internal nut 4a is midway along the bolt 12 and ends as mentioned above when it contacts the head 12a or the lock nut 13.
By arranging that the bolt projects to a greater or lesser amount from the nut at the top of the upper part 2b the length of the game can be increased or decreased as desired.
In a modification, the tube 20 is made considerably shorter than the tube 2b. A second tube 21 has a nut 22 welded therein to receive the bolt 23. The tube 21 is a telescopic tube comprising two parts 21a and 21b, the former being slidable within the latter. A spring 29 is contained within the tube part 21b and acts between a bolt 30 passing through the tube part 21b and the inner end of the tube part 21a. This spring tends to urge the two tube parts apart so that the tube 21 takes up its maximum length. The two tubes 20 and 21 have suction cups 24 or the like at their free ends. The bolt 23 passes through the nut 25. The cord 26 is much shorter than that used in the first embodiment and the ball 27 and the bats used are also smaller and lighter. In particular the ball may be a solid ball.
The modified apparatus is used by inserting the bolt 23 into the nut 22 of the second tube 21 and screwing this up so that the combined length of the two tubes is at a minimum. The tubes are then inserted between the uprights 28 of a door frame and unscrewed so that the combined leng'rhs'of the tube increases to such an extent that the suction cups 24 are forced against the uprights so that the tube is firmly held between the upi without it falling outside the scope of the invention which is determined solely by the following claims.
