Benefits of technology

"The present invention provides a new arrow for hunting and sport archery that has an improved arrangement for mounting and replacement of the fletching. The arrow has vanes that are mechanically mounted on the shaft, eliminating the need for glue and ensuring perfect performance. The vanes are held in position by their foot which abuts against the shaft. This design allows for easy mounting and field replacement, with only the damaged vanes needing replacement. The coupling occurs on the shaft, reducing size, controlled weight, and arrow balancing. The arrangement also reduces turbulence during flight, improving shooting accuracy and delaying the parabola effect. The volume of the arrow is reduced for shipment, with the shaft and vanes being handles separately. These technical effects are achieved by the new arrow design and arrangement for mounting the fletching."

Problems solved by technology

The vanes that are currently used in the art are thin, light, mainly made of synthetic material, and thus likely to be damaged.
Furthermore, it may happen that certain vanes come off during shooting.
Nevertheless, these cuts that extend to the rear end cause the arrow body to be structurally weakened, particularly if such body is made of aluminum or composite materials.
These solutions suffer from a number of drawbacks; first, the interchangeable units are bulky and heavy and may affect arrow aerodynamics and balancing.
Also, all the vanes need to be replaced, even when only one of them is damaged.
Finally, especially in the case disclosed in U.S. Pat. No. 6,695,727, screw coupling to the nock (the arrow shaft) is required, which leads to various drawbacks, such as:Uncertain coaxiality between the interchangeable unit and the axis of the nock, which gives no guarantee about perfect ballistic orientationImpossibility to properly set the position of the added unit relative to the shaft body, namely for the use of arrows with crossbowsImpossibility of forming threads in carbon shafts, which cannot be threadedImpossibility of forming threads in aluminum shafts because, although aluminum is suitable for thread formation, these shafts are not of suitable thickness therefor.

Embodiment Construction

[0031]Particularly referring to the above FIGS. 1 to 7, numeral 10 generally designates an arrow for use in hunting or sport archery according to the invention; it is generally composed of the following parts:[0032]A shaft 3 (or rod) of variable materials, profiles and lengths, generally of circular cross-section (cross sections of FIGS. 2 and 3);[0033]An aerodynamically profiled head 4 (or cusp) of variable materials and shapes or, if designed for hunting use, with blades or knives;[0034]A nock 1 (or rear end) for connecting the arrow 10 to the string of the bow,[0035]A fletching 20 on the rear of the shaft 3, for stabilizing the flight of the arrow 10, which is composed of a plurality, of thin aerodynamically profiled vanes 2 (or feathers), two to six according to the use or the taste of the archer, equally spaced over the outer profile of the arrow (3)

[0036]In modern sport and hunting arrows, the shafts are formed of wood, aluminum, carbon and also aluminum / carbon.

Abstract

An arrow (10) for use in hunting or sport archery, includes a shaft (3) of variable materials, profiles and lengths; an aerodynamically profiled head (4) of variable materials and shapes, having blades or knives if designed for hunting use; a nock (1) for connecting the arrow to the string of a bow; a fletching (20) for stabilizing the flight of the arrow, which is composed of a plurality of aerodynamically profiled thin vanes (2), equally spaced over the outer profile of the arrow and defined by an aerodynamically profiled surface (2B) and a transverse foot (2A). Each vane is fitted into a corresponding slit or aperture (3A) formed in the shaft (3) and its aerodynamically profiled surface (2B) projects out of the slit (3A). Each vane so fitted is held in position by its foot (2A) which is retained within the shaft while abutting against the corresponding surface (3B).

Description

FIELD OF THE INVENTION[0001]The present invention finds application in the field of sport and / or hunting archery, and namely relates to a novel arrangement for mounting the fletching to the arrow before shooting. The term fletching is intended to designate the assembly of elements (generally three), arranged in equally spaced positions on the back of the arrow to stabilize its flight, and also known as compensation vanes. With the present arrangement, these compensating or stabilizing vanes may be easily removed and replaced when damaged, or when a different arrow orientation is desired.BACKGROUND OF THE INVENTION[0002]The vanes that are currently used in the art are thin, light, mainly made of synthetic material, and thus likely to be damaged.[0003]The fletching is formed by gluing, which means that each vane is glued to the outer circumference of the nock, using special jigs or adequate equipment to ensure maximum inclination accuracy between one vane and the other.[0004]Such accu...
