Puska brez puscice ima pozitivno plovnost ^

Demkina gibljiva glava drzi puscico ves cas tesno v vodilu, ne glede na polozaj puske (postrani ali navzdol). Gibljivi del se med strelom dvigne in tako sprosti puscico, istocasno pa ustvari toliko prostora, da prakticno ni mogoce zapletanje vrvice. Glavo je mogoce prilagoditi uporabi puscic ∅6 do ∅7mm. Luknja za vrvico je ojacana z medeninastim vlozkom, kar preprecuje obrabo vrvice pri intenzivni obremenitvi. ^

●

Demka’s articulated muzzle holds the spear firmly in place regardless of the position of the speargun (sideways or upside-down). The moving part is lifted during the launch, releasing the spear and creating enough space for the line of the spear to pass with virtually no danger of entanglement. It has an adjustable socket for spears from ∅6 to ∅7mm. The hole for the reel line is reinforced with a bronze tube to avoid wear during intense movements.

Demka Spearguns was first to manufacture, in 1987, Tahitian spears using stainless steel by SANDVIK with a tensile strength of more than1800¡/mm2.

Demka je v letu 1987 prva pricela izdelovati tahiti puscice iz nerjavecega jekla SANDVIK s trdnostjo vec kot 1800¡/mm2.

All spears by Demka Spearguns have been processed in the area of the cord-hole using the sandblastinc tecchnique, resulting in a dramatic decrease of cord wear.

Vse Demka Tahiti puscice imajo luknje za vrvico obdelane s peskanjem, kar izredno zmanjsuje obrabo in poskodbe vrvice

●

Trigger sensitivity is defined as the level of difficulty with which the trigger of a speargun can be pulled. Pulling a sensitive trigger requires a small force thus contributing to the accuracy of the shot.

●

Trigger sensitivity is given in the form of a diagram showing the force necessary to pull the trigger in relation to the total force applied by the rubber-slings on the spear. In the example of the adjacent diagram it can be seen that when rubber-slings of a total force of 800N are used, trigger 1 needs 14N in order to be pulled while trigger 2 needs only 9N. Therefore, trigger 2 is more sensitive than trigger 1.

●

The range of values (.¯. ±10%) deriving from tests on a sufficient number of samples is also reported (level of confidence: 99%).

The compatibility of a spear with the trigger mechanism of the handle of a speargun depends on the height and tolerances of its interlaced end. Caution is needed because an incompatible spear can be launched suddenly without pressing the trigger thus putting human lives in danger.

●

The appropriate height and tolerances (in mm) of the interlaced end of a spear, in order for it to be compatible with the trigger mechanism of the speargun, are stated.

Prava visina in tolerance (v mm) oblikovanega zadnjega dela puscice za uporabo s sprozilnim mehanizmom sta navedena.

●

Kompatibilnost puscice s sprozilnim mehanizmom je odvisna od visine in tolerance oblikovanega zadnjega dela puscice. Potrebna je velika previdnost, saj se lahko nekompatibilna puscica nenadoma sprozi brez pritiska na sprozilec, kar je lahko smrtno nevarno.

●

Iz primera v diagramu je razvidno, da pri uporabi gum z 800N sile, sprozilec 1 potrebuje 14N za sprozenje, medtem ko potrebuje sprozilec 2 samo 9N. To pomeni, da je sprozilec 2 obcutljivejsi od sprozilca 1.

●

V skladu z Demkinimi Standardi je preciznost strela podvodne puske opisana z razprsitvijo petih (5) strelov v tarco namesceno na doloceni razdalji od vrha puscice.

●

The precision of a speargun reflects its ability to send the spear at the same spot in repeated shots.

●

According to Demka Standards, the precision of a speargun is described by the dispersion of five (5) shots at a target positioned at a given distance from the tip of the spear

The endurance limit of the trigger mechanism is given in Newton (N) units.

●

The endurance limit of a trigger mechanism determines the maximum rubber-sling force that can be safely used on the speargun. If this limit is exceeded then there is danger of failure of the trigger mechanism or the handle with unpredictable consequences.

●

Z ozirom na pomembnost tega podatka za varnost uporabnika, je potrebno upostevati varnostni faktor. Zato je maksimalna obremenitev sprozilnega mehanizma definirana kot 50% od najnizje izmerjene vrednosti sile, ki je povzrocila poskodbo sprozilnega mehanizma med testiranjem primernega stevila vzorcev.

Preciznost strela podvodne puske se odraza v zmoznosti puske da s ponovljenimi streli poslje puscico v isto tocko ^

Spear displacement (m)

●

The range of a speargun is depicted on the energy-displacement diagram, which shows the kinetic energy of the spear (in Joule) at each point on its course. The greater the kinetic energy of a spear is at a given distance, the greater the chances to penetrate a fish located there. In the example of the adjacent diagram, the energy of the spear of speargun 1 is 40 J at approximately 3 meters. The spear of speargun 2 has the same energy at less than 2 meters. Therefore, speargun 1 can penetrate the same fish at a greater distance than speargun 2. In other words, it has a greater range.

●

The shot-velocity of a speargun is depicted on the displacement-time diagram. The "higher" the curve is, the faster the shot of the speargun. In the example of the adjacent diagram, the spear of speargun 1 covers 3 meters in120 millisecond. In the same period of time, the spear of speargun 2 covers less than 2.5 meters. Therefore, speargun 1 gives faster shots at this distance.

●

The time (from the moment the trigger is pulled) necessary for the spear to cover various distances defines a speargun’s shot-velocity. The greater the shot-velocity of a speargun is, the more chances the spear has to reach the fish before it moves out from its course.

●

The maximum elastic bending moment of a spear is the maximum moment to which it can be subjected without suffering significant permanent deformation. In other words, it is a measure of the spear’s ability to maintain its straightness after being subjected to repeated stresses that tend to bend it. Two values of maximum elastic bending moment (in Nm: Newton x meter) must be given for each spear. The first value should correspond to a part of the spear that has not been subjected to machining. The second value should correspond to the area of the slot or the shark-fin. The range of values (.¯. ± 1 Nm) deriving from tests on a sufficient number of samples is also reported (level of confidence: 99%).

Statistically, the strength of a barb corresponds to the maximum bending moment, the application of which does not cause failure to 99% of the tested samples.

The ability of a spear to penetrate a fish depends primarily on its kinetic energy. However, the shape of the nose and the barb, as well as the diameter of the shaft, can make the penetration easier or harder. Standard punching energy is a measure of the influence of these morphological features to

●

Sposobnost puscice za preboj ribe je predvsem odvisna od njene kineticne energije. A tudi oblika vrha in krilca, pa tudi premer puscice, lahko preboj olajsa ali otezi. Standardna energija preboja je meritev vpliva vseh teh morfoloskih lastnosti na sposobnost preboja puscice. Ta specifikacija velja samo za Tahiti puscice.

●

Standardna energija preboja je podana v Joulih (J).

●

Standard punching energy is given in Joule (J). It corresponds to the energy consumed for the penetration of the first 20cm of the spear (including essentially the nose and the barb) to penetrate a standardized specimen. The greater the standard punching energy of a spear is, the harder it is for it to penetrate a fish.

4. OPTIMALNI RAZTEZEK 4. Rubber-sling optimum elongation Za vsak tip gume obstaja raztezek, katerega prekoracitev povzroci ostro povecanje sile napenjanja, ob minimalni pridobitvi (ali celo izgubi) hitrosti strela, istocasno pa se zmanjsa zivljenjska doba gume. Zaradi tega mora biti raztezek, s katerim ima po proizvajalcevih podatkih guma optimalne lastnosti, vedno naveden za vsako gumo.

●

O p t i m a l n i r a z t e z e k je podan kot procent zacetne dolzine (npr. 180-200%). To odgovarja maksimalnemu raztezku, pri katerem, ce je raztegnjena 30 minut, guma obdrzi 95% energije, ki se sprosti ob pocasnem povratku gume na prvotno dolzino.

●

For each type of rubber-sling there is an elongation which, if exceeded, will lead to a sharp increase of the stretching force with minimal gain (or even loss) in the shot-velocity, as well as to a reduction of the rubber’s life-time. Therefore, the elongation at which, according to the manufacturer, the rubber-sling has optimum behavior must be stated.

●

Optimum elongation is given as a percentage of the initial length (e.g. 180-200%). It corresponds to the maximum elongation at which, if the rubber-sling remains stretched for 30 minutes, it will maintain 95% of the energy released during its slow release.
