Description

SUPPORT DEVICE FOR GRIPPING A WEAPON

DESCRIPTION

TECHNICAL FIELD

The present invention relates to handguns or products whose use requires the aim and it refers to a support device for gripping a weapon particularly suitable for facilitating taking and instinctive aim of revolvers, pistols, weapons and other firearms as well as devices, such as remote detectors, designators, pointers, meters, hand tools and the like that require manual aiming.

BACKGROUND ART There are known firearms, such as pistols, revolvers, etc. which can by manually handled, equipped with a grip, sometime provided with side pads, assigned to be gripped to facilitate aiming and to counter the recoil. There are many known techniques to grasp such known weapons, for example with only the strong hand, with the weak hand that tightens the wrist of the strong one or that supports and sustains the latter from the bottom.

A disadvantage of these known weapons consists in the fact that they lend themselves to the adoption of techniques that satisfactorily solve only some shooting problems leaving others unresolved, for example the stability of the fire line or the return thereto or of instinct or control of the recoil or its rise, etc.

For example, a gripping technique is currently very well established and widespread, which provides that the index finger, middle finger and little finger of the weak hand, rest against the front part of the stock or grip, overlapping the middle and little finger of the strong hand. Then the palm and the thumb of the weak hand, of a right-handed user, are positioned respectively on the left side of the grip and below the thumb of the strong hand. This known technique provides that the weak hand has the task of holding the pistol and the strong hand has the main task of pulling the trigger and providing the 40% of the gripping while the remaining 60% is then given to the weak hand. It is also expected that the strong hand pushes the pistol forward while the weak hand pulls in the opposite direction, so as to increase the grip. This causes a considerable effort on the user's limbs, with consequent difficulty in concentrating and maintaining the aim in particular by poorly trained or weakly trained or weak shooters or even by trained experts weakened by trauma, fatigued by physical exertion or subjected to particular stress.

Some known grips are provided with anatomically shaped side pads or linings, sometimes tailor-made or molded by the user's hand, to facilitate aiming and shooting. A disadvantage of such shaped grips consists in the fact that they fit only for sport shooting weapons as they generally fit only one shooter, they are expensive and bulky and are also not fast enough to grip.

The prior art document US 2013/0074351 Al refers to an assembly for LASER pointing in a weapon and provides a LASER switch comprising an arm, or which is connected thereto, which can be configured in such a way as to be movable transversely between a central position, turning off the LASER and two right and left ignition positions. In the central switch off position the arm ends are accessible from each of left and right sides of a casing of said assembly by virtue of making lateral housings for arm ends, for example consisting of depressions or recesses (indicated by the reference 31 in Figures 1-3 of the previous document in question), and sizing the arm. The switch can then be operated by the user on both sides of the housing. The outer surface of the housing may therefore include recesses, depressions or hollows 31 adjacent the ends of the switch arm so that the switch is movable relative to the housing while, at least initially, it is included in the housing width. The LASER is then turned on by pressing the arm end with the index end with consequent contact between the finger and the depression housing this end with functions related to access to weapon And to housing of this latter. The earlier document US 2013/0074351 Al does not contain suggestions or incentives to adopt indentations to position the index in order to stabilize, facilitate or improve the aim and/or the shooting with the weapon.

The earlier documents US 3,758,978 and WO 02/093100 disclose arms provided with an grip improver for a finger or a pocket for an index respectively fixed or obtained in the medial frontal portion (i.e. facing towards the muzzle of the weapon) of the trigger protection guard. Such grip and pocket improvers roughly reproduce the shape of the trigger.

With reference to Figures 1-4, numeral 1 indicates the device, object of the present invention, for gripping a weapon A, for example a revolver, pistol or other weapon with a grip to be held, equipped with a barrel N with a muzzle V and a shot members including a trigger G protected by a trigger bridge or guard P extending from a receiver or drum C to a grip or handle L of the weapon A; the weapon further comprises aiming members, for example, a notch or diopter and sight and possibly red dot sights, telescopic sights, LASER pointers and the like. The window circumscribed by the trigger guard P, by the receiver C and by the grip L constitutes a housing for the trigger.

In an using condition of the weapon by a shooter, in particular in aiming and shooting condition, said window also houses a finger, generally the index finger of the strong hand of the shooter.

Alternatively, the device can also be applied to a tool or to a remote detector equipped with parts similar to those of a pistol, for example to a remote spot reading thermal detector. Said device 1 comprises a match means 3 formed in or fixed to a side face of the receiver C and/or of the trigger guard P of weapon. Preferably the match means 3 is placed immediately in front of the window which acts as housing for the trigger and bounded by the trigger guard P and below the or in the lower area of the receiver C. The match means 3 is preferably fixed to the side of the weak hand of shooter or the invention provides for the adoption of two match means 3, one on the right side and the other one on the left side of the weapon for an ambidextrous function.

This match means 3 is assigned to act as an abutment and/or support and positioning at least for the fingertip or distal phalanx of the index finger of shooter weak hand during the use of weapon A, in particular during aiming and shooting.

For this purpose the match means 3 can comprise a hollow 5 whose perimetrical edge describes a polygon, a rectangle or preferably an oval or an ellipse. The main geometrical axis of the oval or elliptical perimeter is approximately parallel to the barrel N or slightly inclined towards the muzzle V of barrel N.

As shown by way of example, the hollow 5 formed in or attached to a side of weapon may be shaped with a longitudinal cap of an ellipsoid or solid obtained by rotation around the major axis of ellipse or oval or closed curve. The concave surface of the hollow 5 faces to the opposite direction to the median longitudinal plane of the weapon so that the fingertip of the index finger of the shooter's weak hand has stable and precise positioning and orientation; in particular, the edge portion placed towards said muzzle V is designed to match with the tip of fingertip of said distal phalanx and the cavity of the hollow 5 houses a portion of said fingertip. The match means 3 is placed at a first distance Dl from the longitudinal geometric axis of the barrel N so as to allow the shooter, at least in aiming and shooting condition, to place under thumb of the strong hand, the thumb and the index finger of the weak hand.

The first distance D 1 is determined to maintain the index finger of weak hand of the shooter, in aiming and shooting condition in which the index fingertip of the shooter's weak hand is positioned against the match means 3, parallel to geometric axis of barrel N or slightly inclined towards the muzzle V.

The match means 3 is placed at a second distance D2 from grip L of weapon A so that the index finger of shooter's weak hand in aiming and shooting condition is straight or slightly arched.

In the aiming and/or shooting condition, the match means 3 thus provides a housing and a precise positioning at the distal phalanx or fingertip of the index finger of the weak hand whose fingers can all stay at corresponding side of weapon with middle, annular and little fingers folded and partially overlapping the corresponding fingers of strong hand that grasps the grip. The thumb of the strong hand is at least partially in contact with weapon side on the side of weak hand and is placed under the firing hammer and above the thumb of the weak hand as illustrated in Figures 8 and 9 while the index finger of the weak hand is straight or slightly arcuate, as illustrated in Figure 9, when its fingertip is positioned onto the match means 3. Obviously the device does not prevent or hinder other known or new grip and shot techniques.

Alternatively, or as shown by way of example in the figures, in addition to hollow the 5, the match means 3 may comprise a rib or arch relief 7 whose geometrical chord is approximately perpendicular to the barrel N or slightly inclined. The concavity of relief 7 is directed towards the trigger G. In the case of simultaneous presence of the hollow 5 and of the relief 7, the chord of the latter can be perpendicular to the main geometric axis of the hollow 5. The relief 7 is placed at the edge portion of the hollow 5 facing towards said muzzle V.

This relief 7 is designed to match with the tip of fingertip of said distal phalanx of the weak hand or with a corresponding portion of a glove fitted by said hand.

The match means 3, comprising the hollow 5 and/or the relief 7, is formed in a portion of the receiver C and/or of the trigger guard P of weapon or in a suitable extension thereof. Alternatively, the device may comprise an optional base means 9 fixed to a portion of the receiver C and/or of the trigger guard P of the weapon and bearing the match means 3, comprising the hollow 5 and/or the relief 7.

The invention further provides that the base means 9, in metal or in synthetic material, is rigidly fixed to the receiver C and/or to the trigger guard P by gluing, screws or interlocking or that the base means 9 is fixed to the receiver C or to a rail (for example Picatinny) of the weapon A rigidly or by means of sliding means designated for positioning and/or the adjustable orientation of the hollow 5 and/or of the relief 7. This adjustable fixing allows to adapt the weapon equipped with the device to different shooters and/or shooters with different styles or aim and shot techniques.

Preferably, and in particular in case of realization of match means 3 during the production of weapon, this match means 3 is constituted by the hollow 5; the match means 3 of the relief type 7 can be easily applied, even by simple gluing or by means of screws or the like, to the receiver C of some weapons also as an after-sales accessory; the match means 3 comprising the base means 9 which in turn carries the hollow 5 and/or the relief 7 can be carried out during the production of weapon, and can be applied as subsequent application as an after- sales accessory for weapon; the relief 7 is particularly useful in case of weapon held by gloved hands. The base means 9 can be provided with the hollow 5 and with links for the removable connection of the relief 7 which can thus be installed only in case of need or as desired by the shooter. The base means 9 can be made in a single body with the receiver C of the weapon A or it can consist of an element fixed to the weapon and made of materials selected among metal, plastic, resin, reinforced resin, rubber, elastomer material, wood or substitutes for wood. The surface of the match means 3 designed to match with the fingertip can be provided with at least one among knurling, high friction surface, coating of high friction and/or synthetic material.

In the variant of Figure 5, the match means 3 comprises a hollow 5 and/or a relief 7 for each side of the weapon A or the base means 9 has a match means on the right and one on the left to make the device ambidextrous.

In the variant of Figure 6, the base means 9 is thin and centered on the median plane of the weapon to bring the match means 3 closer to said median plane.

In the variant of Figure 7, the base means 9 is thick and centered on the median plane of weapon to move the match means 3 away from said median plane and to provide, on the right hand side, a plane which can be used for a further possible match means 3. The variant of Figure 10 provides positioning means first 11 and/or second 13 designed to match with the ends or the fingertips of the thumbs respectively of the strong hand and the weak hand of the shooter. The first positioning means 11 is higher than the second positioning means 13 and each of them consists of a convexity formed on a weapon side or in a projection or protrusion carried out or fixed on this side of the same side of weak hand. The first 11 and/or second positioning means 13 are particularly suitable to be carried out in the form of arcuate ribs made of plastic and provided with adhesive for fastening to the receiver of weapon.

The first 11 and second 13 positioning means are preferably located in the area between the firing hammer and the trigger. The invention provides that the weapon is provided with both the first 11 and the second 13 positioning means or only one of them. A possible, but obviously not unique, use of the device can take place according to peculiar gripping technique, aim and shot described above which ensures a low waste of physical energy and therefore the ability to maintain for a long time the weapon aimed at a steady or in motion target, so allowing a high concentration of the shooter, avoiding the application of excessive opposing muscular forces to the weapon and unbalanced torques that can, especially during the recoil, cause the weapon rotation even on different levels from that of the same recoil. The countless tests, trials and comparisons, have shown that said weapon handgrip manner, made possible and/or facilitated by the device 1, facilitates, speeds up and stabilizes the aim and shot of a target and facilitates and speeds up the return to the correct aim line after each shot. The tests showed better scores, compared to the known two-hand grip modes, in all shooting disciplines including instinctive shooting.
