Description

Singapore Sling
Technical Field
For installing an antenna wire over predetermined objects there are several apparatuses on the market. The most used technique moves a carrier with an attached cord over a predetermined object.
One variation bf an antenna launcher is a sling shot. One will shoot a lead sinker with an attached cord over a predetermined object. A major disadvantage of this system is that in most countries sling shots are classified as weapons and hence illegal. Further it is only possible to use very small throwing weights. So the weights must be made from heavy material which can cause damage during the installation process.
Another possibility is the usage of a bow and arrow. Here similar problems arise. An additional problem is that bows are comparatively bulky.
A third way to install an antenna wire could be a pneumatic antenna launching system. It is a system that uses the energy stored in a pressurized volume of gas (generally air), a valve to release the gas, and a throwing weight (tennis ball) placed inside a tube. The throwing weight is then accelerated by the expanding gas giving it the requisite velocity to pull a light cord over a predetermined object. The tubes for the launcher are usually made from PVC. The manufacturers of PVC tubes and fittings do not recommend its use with compressed air. If a PVC tube containing compressed air is fractured, it may result in high velocity PVC shrapnel. So avoid breaking it while it is pressurized, and wear safety glasses when using launchers or any power tool. Low and high temperatures make PVC brittle or soft so launchers based on pneumatic principles should not be used in extreme temperatures. This system could be classified as a weapon in several countries. Further more it is also bulky.
Brief Description of Figures
FIG. 1 illustrates a perspective view of an embodiment of an antenna installation whip, and FIG. 2 illustrates a side view of an antenna installation catapult.
Modes for Carrying out the Subject Matter of the Application FIG. 1 shows an antenna installation whip 1 which comprises a ball throwing rod 2 with a spinning reel 3 attached thereto.
The spinning reel 3 comprises a nylon line 4 which is equipped with a rubber ball 5 at its end.
The ball throwing rod 2 includes a ball scoop 6 at its top end, a shaft 8 in its middle part and a handle 9 at the bottom end part. The shaft 8, the handle 9 and the scoop 6 which are manufactured integrally are made from plastic in a die casting procedure. The size of the scoop 6 is adapted to initially secure the rubber ball 5 and to release it by a predetermined amount of propulsive force. The ball scoop 6 comprises two laterally retaining fingers 24 and an upper and lower retaining frame 25 for securely fastening the rubber ball 5.
The shaft 8 is the thinnest part of the ball throwing rod 2.
It tapers from a thick part, starting at the handle 9, to a thin part at the scoop 6. The profile of the shaft 8 is rectangular. It is curved backwards away from the handle 9 and it is flexible. The handle 9 is the thickest and strongest part of the ball throwing rod 2. It includes on its front face a plurality of recessed grips in the form of curves 10 that are designed to match the fingers of a user.
A guide lug 7 is attached to the upper part of the shaft 8 to guide the nylon line 4 between the rubber ball 5 and the spinning reel 3. The guide lug 7 is Teflon-coated to provide a better gliding action of the nylon line 4 through the eyelet 7. The eyelet 7 and the spinning reel 3 are placed on the same side of the shaft 8.
A sleeve 14 is rotatably supported in a casing 15 of the spinning reel 3 so that said sleeve 14 is turned integrally with the handle shaft 11 in a known way. This sleeve 14 carries at its end a rotor 17 which has a veil 16 and also has inserted thereinto the spool shaft 18 on which a spool 12 is mounted. The spool shaft 18 is arranged reciprocatable slidingly in the sleeve 14 with rotation of the handle shaft 11 in a well-known way. It will be also noted that a click gear 19 and a ratchet 20 are fixed overlapping each other in the outer peripheral portion of the sleeve 14 in the projecting portion of the casing 15 and behind the rotor 17.
The spinning reel 3 also comprises a T-holder 13. The spinning reel 3 is connected with the ball throwing device 2 via the T-holder 13.
Further details of the spinning reel 3 and of its operation can be taken from US-Patent 4,163,528.
One end of the nylon line 4 is attached to a snap hook 21, which is connected to a ball connection line 22. The rubber ball 5 has a through hole 23 which extends through its center.
The ball connection line 22 is fed through this through hole 23. The ball connection line 22 is connected as a loop and it is attached to the snap hook 21 which is of such a size that it easily passes through the through hole 23. The ball connection line 22 may be released from the rubber ball 5 The antenna installation whip 1 as provided here is made from fishing tackle oft-the-shelf parts which are easy to source and maintain. The spinning reel 3 is field tested. The rubber ball as provided here causes no damage it it hits an object or a person during the installation process of an antenna wire.
No part of the antenna installation whip 1 is forbidden as a It is possible to use a metal antenna wire such as copper instead of the nylon line 4. Further, a lead weight or a sinker can be used instead of the rubber ball 5.
The integrally formed ball throwing rod 2 could be replaced by a telescopic shaft or by a pluggable shaft. It is also possible to produce the shaft 8 from fiber glass.
The antenna installation whip 1 can be used for installing a wire antenna over a high object, by propelling the rubber ball over the high object. Therefore one will provide a rubber ball 5 and connect it with the nylon line 4 by using the snap hook 21. Then one will press the rubber ball 5 into the scoop 6 and tighten the nylon line 4 by turning the handle shaft 11 in the appropriate direction.
Next, one will turn down the veil 16 to release the nylon line 4 from the spinning reel 3.
Then a first person will strike out with the antenna installation whip 1, while holding it with one or two hands at the handle 9 and while securing the nylon line 4 with one finger to the shaft 8. The open side of the scoop 6 must point in the direction in which the rubber ball 5 is to be thrown.
The rubber ball 5 is a weight, which brings the line 4 over a high, predetermined object. Therefore one will aim over the high object over which the antenna wire should be placed and than one will move the ball throwing device 1 fast in the same direction.
At a predetermined position during this movement the ball throwing device 1 has to be stopped suddenly. With some practice one will know the moment in which the shaft 8 is orthogonal to the throwing direction which leads towards a desired result. Its inertia causes the rubber ball 5 to leave the scoop 6. From this moment on the flying rubber ball 5 carries the nylon line 4 over the predetermined object. The nylon line 4 keeps unreeling from the spool 12 while the rubber ball 5 is traveling over the predetermined object.
After the rubber ball 5 has carried the nylon line 4 over the predetermined object, a second person will disconnect the rubber ball 5 from the nylon line and connect the wire antenna with the nylon line 4 by hooking a loop at the end of the antenna wire into the snap hook 21.
The first person will pull back the antenna over the high object by rotating the handle shaft 11 thereby pulling the nylon line 4 with the antenna wire back. In the meantime, the second person aids the smooth movement up of the antenna wire which is hooked up to the end of the nylon line 4. After the antenna wire has reached its end position, the first person disconnects the antenna wire from the nylon line 4.
It is easy to place an antenna wire over a high object with the antenna installation whip 1. The aforementioned steps can easily be performed by big or small persons alike.
One further way of installing an antenna wire is to replace the nylon line 4 with a thin, flexible metal antenna wire which is wound up on the spinning reel 3.
One will then connect the antenna wire which is wound up on the spinning reel 3 directly to the rubber ball 5.
Than one will clip the rubber ball 5 into the scoop 6 and tighten the antenna wire by turning the handle shaft 11.
Next, one will turn down the veil 16 to release the antenna wire from the spinning reel 3.
Then one will strike out with the antenna installation whip 1, while holding it with one or two hands at the handle 9 and while securing the antenna wire with one finger to the shaft 8. The open side of the scoop 6 must point in the direction in which the rubber ball 5 should be propelled.
The rubber ball 5 is a weight, which brings the antenna wire over a high predetermined object. Therefore one will aim over the high object over which the antenna should be placed and than one will move the ball throwing device 2 fast in the same direction.
At a predetermined position during this movement the ball throwing device 2 has to be stopped, with some practice one will know the moment in which the shaft 8 is orthogonal to the throwing direction which leads towards a desired result. Its inertia causes the rubber ball 5 to leave the scoop 6. From this moment on the flying rubber ball 5 carries the antenna wire over the predetermined object. Antenna wire keeps unreeling from the spool 12 while the rubber ball 5 is traveling over the predetermined object.
After the rubber ball 5 has carried the antenna wire over the predetermined object, one will cut off the antenna wire from the spinning reel 3.
A further embodiment is shown in FIG. 2. The antenna installation catapult 26 of FIG. 2 is similar to the antenna installation whip 1 of FIG. 1. Similar parts have the same reference number.
This antenna installation catapult 26 comprises an upper shaft 27 and a lower shaft 28. Between these two parts there is provided a pivoted joint 29. This pivoted joint 29 comprises a stop. This stop ensures that the flip movement ends when the upper shaft 27 and the lower shaft 28 are in a straight line.
The embodiment shown in FIG. 2 comprises also a handle 9' at the lower part of the shaft 28. It includes a plurality of recessed grips in the form of curves 10' that are designed to match the fingers of a user. There is a spinning reel 3' which is connected with the rubber ball 5' by a nylon line 4'. The rubber ball 5' can be clipped into the scoop 6'. Therefore the scoop 6' comprises two laterally retaining fingers 24' and an upper and lower retaining frame 25' for clip fasting the rubber ball 5'. The retaining fingers 24' and the retaining frames 25' are not shown in Fig 2.
While striking out with the antenna installation catapult 26 the upper shaft 30 flaps with its back part into the direction of the back part of the lower shaft 28. At a predetermined position during this movement the ball throwing device 2 has to be stopped suddenly. With some practice one will know the moment in which the shaft 8 is orthogonal to the throwing direction which leads towards a desired result. This movement causes the upper shaft 30 to flap in the opposite way until the upper shaft 27 hits the stop 29 to give the rubber ball 5' inertia. Its inertia causes the rubber ball 5' to leave the scoop 6'. This flap-movement can increase the propelling effect by providing an additional leverage on the rubber ball 5'. The installation procedure is largely the same as described for the antenna installation whip shown in FIG. 1.
Both nylon lines and antenna wires can be used with the antenna installation catapult 26.
The antenna installation whip 1 can be made from plastic or fiber glass. Both materials are flexible and they increase the propulsion effect. Fiber glass would be the lighter in weight.
The two laterally retaining fingers 24 and the upper and lower retaining frames 25 of the scoop 6, are slightly flexible so a throwing weight such as the rubber ball 5 can be clipped firmly in place.
The throwing weight can be, made of rubber or lead. If a rubber ball 5 is provided as a throwing weight it will not cause any damage during the installation of the antenna. If the throwing weight is made of lead it would be much smaller and one could install longer antenna wires.
The spinning reel 3 can be of the type which is used on fishing tackle. These reels are readily available in the
market, easy to use and are field tested.
The advantage of using an antenna wire instead of a nylon line is that the antenna is installed immediately after the throwing action. One single person can install a long wire antenna therewith.
The advantage of using a nylon line instead of antenna wire on the reel is that it is possible to use a thicker, stronger antenna wire because only thin and flexible antenna wires can be used on the spinning reel 3.
