Abstract

The invention consists of one or more mobile foresights of suitable material lighted by a set of direct or transported light with optical fibres to make the hitting of the bull easier even in conditions of insufficient light with fire arms of any kind and with those jet ones (compressed air and spring carabine, or string-arms as bows, corrbows and the like).

Description

The inventions consists of one or more mobile foresights of suitable ma terial lighted by a set of direct or transported lights with optical fi bres to make the hitting of the bull easier even in conditions of insuf ficient light with fire arms of any kind and with those jet ones (compressed air and spring carabines, or string-arms as bows, crossbows and the like).
By the actual state of technique, the present foresights don't allow to aim at targets when light is insufficient.
It is known that under a certain luminous threshold the human eye, less sensible than that one of other animals, is not able to aim exactly and in a short time: if he sees the beginning of the sight in a hunting-arm, he won't see the muzzle of the barrel.
This is the reason for which the undersigned decided to studv accurate- lv how to equip an arm to use also with scarce light in a manner, which is simple, not very expensive and suitable to any arm, also already in use, with a mobile apparatus that allows at any moment to take, in few seconds, the arm to pieces for the cleaning, reparation or transport in a case without using any tools.
Besides, he wanted the apparatus to be pocket, strong, protected from collisions or vibrations, and hermetictight closure against dust, humi dity and water; to be able to be taken off when it wasn't useful and to be inserted in few seconds as soon as necessary.
Suitable to anv fire and jet arm, as spring and compressed air guns;and to any string-arm, as bows and crossbows also for competitions.
This apparatus - from now on, for the sake of brevity, it will be cal led "the invention", - consists (see enclosed Table n. 1, Pict. 1) of a foresight (1) of suitable material, which is also transparent or opa que partlv, containing a microlamp (2), fed by a bipolar little cable (3), enameled or under sheath, or monopolar if the earth can be utilized, connected with a battery or an accumulator of any kind, preferably from a mercury or silver oxide batterv (1,4 - 1,5 v), because, for low consumption, thev last many hours, they last many hours, they weigh about two grams and are as large as a nail, contained inside a container (5) of suitable form together with an ignition button, preferably like a bell bv pressing, it closes the circuit and opens it when pressure stops.
Dimensions of lamp and eventual slits (7) (and their form) in foresight (1) are such as to eliminate any dazzling or diffusive halo that could prevent a right aim.
In double-barrelled gun (Pict. 4) the foresight (1), with slit (7) and joint feet (9), overlaps with pressure on sight (10).
In Pict. 2 other two types of foresight - among the manv we can use for our invention - with slit (7) and magnetic paste of attack (11) and with slit (7B) .and joint feet (9B) for monobarrel (Pict, 5 and 6) are represented.
The wire (3) runs near the sight (10) along the line (8) (or between bar rels (Pict. 5) or sideways to the barrel (Pict. 6) and, the container (5) with battery and button is stuck to the under barrel (12), where, on shot the fingers of the hand that hold up the under barrel can press the button (6).
Similar solutions (not represented) allow to utilize the invention for other fire and jet arms.
A second solution, very practical, to lead a luminous point or sign in the foresight, consists in assembling (Pict. 3) the battery (4), the but ton (6) and the lamp (2) inside the container (5).
An optical fibre (14) - or a thin beam of optical fibres with a smaller diameter - sheathed or not, will joint the foresight (15) that must be lighted with the inside of the container (5) through a little hole (16), gaugetight.
The invention will be placed, as already above-mentioned about the guns in Pict. 4,5 and 6, with the difference that the lamp (2), moved from the barrel to the under barrel (12), that, with blows, has less vibrations and, well protected inside (5), eventually packed with foam rubber or the like (17) (dashed in Pict. 3), will last unlimitedly.
In fact it will be switched on by the shooter some minutes before shooting and switched off immediately afterwards.
After firing hundreds of shots it will be still lighted for few hundreds of seconds, i.e. some minutes at the most.
The power consumption will be about 300 milliampere in an hour and the life of the battery over 12 hours - i.e. only with a battery, over 10.000 shots could be fired.
Naturallv the optical fibre (14), inserted with an extreme in (5), will have the other extreme (18) inserted in the luminous foresight (15) (Pict. 3) with the last section (19) turned towards the shooter's eve, i.e.towards the butt (20) of the arm.
The optical fibre (14) will be able to have any section.
The invention will be composed of one or more foresights (with slits mo del 7, or 7A or 7B or other similar), the electric little cable (3) or the optical fibre (14), and the container (5) equipped as in Pict. 1 or in Pict. 3.
The above-described set will be able to stay in a small sack or cas, as big as o box matches, of short weight and low price and it will be able to be bought and applied to arms alreadv in possession of the buver or together with the arm, for its equipment.
The container (5) will be able to stick to the under barrel (12) (Pict. 4) with two magnetic pastes fixed with bioadhesive to the under barrel and to the container, or, in the same wav, with two tongues of velcro, or with dovetails.
Or, on the other hand, it will be able to stay in a cavity inlaid on the under barrel (12), leaving the only button of the interrupter, to stick out.
In this way the visible side of(5)will be able, anyhow, to be doodled in the style of the arm, and it will be able to have, in protection of the invention the milled mark of protection that marks it.
The container will be able to open in (13) to take the place of battery, lamp or interrupter; the wire (3) or (14) will be able even to be replaced if damaged; and, in the foresight with lamp, this one will be able to be replaced, lodged in the way of screw, of embedding or in another similar way.
