L'arc - as an instrument of aggression (as a weapon) but also as a tool for hunting, recreation and sport - is certainly one of the most original inventions of man, who developed it in various parts of the world, in times different and independent in each case is one of the first devices developed primitive.
It is believed that the first depiction of an arc can indicate a graffiti for about thirty years ago.Certainly since Paleolithic man was using this tool as a way to hit a hunting prey, keeping a safety distance.
The archery appeared for the first time the Olympic Games of 1900 in Paris. Excluded after 1920 was readmitted from Monaco Munich Olympics of 1972and since then is a specialty sports that brought several medals to the Azzurri.
In Italy the archery was long considered little more than a pastime for boys, began to be practiced as a sport in the thirties, under the fascist regime: this was indeed the fate of the "Young Italian". He also organized a women's league sponsored by the Academy of Physical Education in Orvieto. In1956 in Treviso took shape, the first company ("Company") will play the Italian and the first competitions to be organized, open to both genders.
Components and accessories
Each arch is composed of several parts. The different types of existing arc can be distinguished:
· riser (or handle)
· Limbs
· Rope
· Button
· Rest (or Poggiafreccia)
· Stabilization
· Clicker
These are some accessories arc:
· Arrows
· Dragona
· Patelletta or glove
· mechanical release
· Quiver
· Protectors
Riser
The riser is the central arch, the part that holds up through the grip (handle) to pull. There are different types of materials (wood, aluminum, carbon) and lengths, made with different techniques including casting and machining of a block of metal. TD in the strings ("take down", removable) is the medium on which are mounted the limbs, but also support many accessories such as bead, button, "rest" and "clicker".
Bending
The limbs are, as the name implies, the part the arch flexes. Are constructed in various materials (wood, carbon fiber, ceramics) and characterized by two parameters (length and libraggio) which vary and are chosen on the basis that the archer will use them. TD in the strings are split to fit on the riser, in monolithic arches are a natural extension of the handle.
The rope
The string may consist of filaments of different materials, natural fibers (eg, linen) or synthetic fibers. In the central part of the rope is more often a filament (called "serving") which are fixed points that indicate where to be positioned nock the arrow. Depending on the type of straw stand strings like "continuous"and cord type"flemish". Ropes in continuous loops (rings through which the rope tenses the arc) are achieved by widening the strands at the ends and wrapping them with a serving (actually these strings are composed of a single filament that makes a lot of laps (12 or more .) In the Flemish instead account for a particular splicing the two ends of the rope.
Compound bows strings do not fall into these two categories because almost every model of this type of learning requires a particular set of ropes and cables.
Button
Formally known as "elastic button" or "button pressure, often called" Berger Button "by its creator, is a cushioning system that lets you adjust the flexibility of the arrow, also called" thorns ", the actual power (or weight poundage traction) of the arc. There are several types on the market, with more or less accurate adjustment of the spring pressure.
The rest
The rest is the medium in which the arrow rests. As there are different types, from plastic adhesives to the metal with support screw.
The viewfinder
The viewfinder is a tracking system, set at the discretion of the arc, depending on the distance to target or light conditions and weather (various types of wind). There are different models, depending on the type of bow used. Fixed size in diameter and width of the diopter, without the magnifying glass to bow recurve (Olympic), with a different lens and diopter adjustment for the compound bow (with scalers eccentric arc power) that can use the magnifying glass of the diopter, a bubble level to better align the bow to the target.
The stabilizer
The stabilizer is a rod that serves to limit the oscillations of the arc. May consist of several parts: the compound bows generally use a single central stem, while the Olympic arches will also add two shorter bars (called "whiskers") placed laterally approximately 45 ° inwards.
Clicker a metal tab that acts as "motivator release and extension", ie in the bow is achieved throughout the length of the arrow can, archer ensuring a constant extension. Its name derives from the "click" that occurs when the arrow leaves the metal tab, just before the stroke of the arrow.
The arrows
As the bow the arrow has also been transformed over the years. From cedar wood or lime has passed aluminum arrows, and then to come to auction carbon and aluminum / carbon fiber. Note however that are still used all types of material, depending on the specialty practiced. Diameter, length, weight, type of impennatura or arrowheads to be used are always in relation to physical arc, the arc power and the type of shot (Indoor, FITA, Field & Hunter, etc..). In general, larger diameter arrows can cover more area on the view (the target) but are more subject to wind and wrong movements, while the thinner arrows are faster and lighter.
The Dragon
The sling (or "leash") is a string that ties hand of the riser so as not to lose the arch during delivery. There are two main types: those that bind to finger and those that bind to the wrist.
The patelletta
The patelletta (or "tab") is composed of several layers of skin, leather or synthetic materials.Serves to protect the fingers pulling the rope from abrasion and cracks that are caused by the release. They come in various sizes, shapes and colors, the ideal is modeled on the fingers of the archer who must use it. For Division barebow FITARCO the patelletta must be seamless, which could serve as a reference archer. In some specialties patelletta you prefer a traditional leather glove reinforced with three fingers (index, middle, ring) that allows a faster shooting.
The mechanical release
The mechanical release is an accessory for the 'compound bow, used to release the rope, in fact replaces patelletta or protect the glove fingers. The fingers of the archer will not touch the rope and almost completely eliminate the potential interference of a manual release. They come in different colors and types, that radically change the mode of release: there are tripping pressure, rotation, back-tension ", held by a band on the wrist or fingers.
The Quiver
The Quiver is the container of the arrows. There are many different types of leather and fabric, from back or side. Many archers alone realize its quiver, the other only customize, attacking pins and merit won, or simple luck.
Guards
The guards who can use a archer, in addition to patelletta, and armguard paraseno (also used by men). Can be constructed in different materials, from leather to plastic, from natural or synthetic fabric. Serve to protect the archer from the blows and abrasions caused by the cord during delivery and, above all paraseno to ensure the rope a constant friction with the body of the archer, limiting the possible interference.
