Definitions
- the present invention relates to a stock for rifle which can be fully adjusted both vertically and laterally and, by means of appropriate thicknesses of the butt plates, also in length.
- Stocks for rifles are known on the market, above all in relation to the world of precision or sport shooting, which are known as "adjustable" due to the possibility of partially adjusting the shape of the stock, improving the support provided for the shooter during shooting.
- aim refers to the alignment between the eye, the shoulder and the line of aim of the rifle: clearly, when producing a rifle stock, account has to be taken of a set of parameters such as distance and height of eyes, position of the cheekbones and the extent of their projection, the length of the neck, the position of the shoulder whereon the rifle is rested, and the length of the arms and height of the person.
- the object therefore of the present invention is that of producing a stock which can be fully adjusted and adapted to the shooter, in such a way that perfect alignment of the aim on the target to be hit can be achieved, with a lower likelihood of error on the same target.
- a further object of the present invention is that of simplifying the production of the stocks: today's production method is in fact that of producing the stocks in different sizes with an increase in costs and a further complication, as for each model of rifle numerous sizes of stocks have to be produced to satisfy customers who obviously have heterogeneous physiques.
- the production of the stock according to the present invention enables a saving in materials, above all wood, and a considerable decrease in costs, improving the efficiency of production.
- a further advantage achieved, as will be illustrated herein below, is absorption of the recoil by the stock forming the object of the present invention, as it is no longer a rigid single part but is instead formed by two joined elements: the system which joins the two elements introduces a restraint which increases the elasticity of the body and therefore encourages absorption of the recoil which is not transferred directly to the shoulder but is damped by the connection system.
- Fig. 1 illustrates the complete stock as it is presented.
- Fig. 2 shows the elements which form the stock and the system of connection of the elements.
- Fig. 3 is a view from above of how the stock is presented perfectly in line with the barrels.
- Fig. 4 shows the various types of butt plate which can be attached to the end of the stock to adapt the rifle in a longitudinal direction.
- the stock is formed by the union of two elements wherein element 1 is integral with the breechblock 3 of the rifle and therefore with the barrels, while element 2 rests on the shoulder of the shooter. On element 2 the nose 4, the heel 5, the tip 6 and, in contact with the shoulder, the butt plate 7, can be seen.
- the stock consequently appears divided also from a structural point of view: from a rigid body formed by a single piece of wood as it was originally, it becomes a body formed by two separate elements joined to each other and with different tasks and functions: the union of these two elements forms the actual stock.
- the elements 1 and 2 are joined to each other by means of pins 8, whose ends are attached to the elements 1 and 2 by means of plates 9 which are embedded in either one of the elements forming the stock as described above. Said plates can regulate micrometrically the position of the ends of the pins 8 in a transverse direction to the stock, as said ends are attached to a worm screw.
- regulation of the horizontal movement of element 1 in relation to element 2 therefore takes place with micrometric regulation of the position of the pins 8 by actuating the screws 10 which move the point of attachment of the pin in a transverse direction, enabling translation (moving both pins 8 in the same direction) or rotation (modifying the position of the pins 8 in opposite directions or adjusting only one thereof) of one element in relation to the other.
- the system of attachment of the butt is by bayonet coupling of the attachment holes 13 on special pins formed in the end part of the stock.
- Adjustment takes place with replacement of the butt plate with others 7', 7", 7'" of different thickness which allow optimal adaptation in a longitudinal direction of the rifle to the shooter.
