Description
[0001] The present invention refers to a stock for a firearm made
from polymeric material.
[0002] A stock for a firearm generally has a complex geometry,
designed based upon ergonomic, structural and even aesthetic
requirements.
[0003] Moreover, a stock, realised both in solid configuration,
from wood, and in skeleton configuration, from metal, represents a
useless and disadvantageous weighing down of the firearm.
[0004] Wood, moreover, does not allow complete workability and,
under certain thicknesses, does not have good structural
resistance.
[0005] By using polymeric materials for the moulding of the stock
of a firearm it is, on the other hand, possible to reconcile
complexity of the shape with lightness of the structure.
[0006] A stock for a firearm must, however, also ensure good
structural resistance, since the firearm can be used to knock down
obstacles, or at least be subjected to substantial stresses during
use, or in the case of the firearm itself being dropped.
[0007] A stock for a firearm made from polymeric material can be
realised in the form of two moulded half-shells, each of which
equipped with suitable rigidifying ribs, connected together through
gluing, welding or mechanical attachment.
[0008] Nevertheless, in welded products the welding burrs between
the two half-shells, which represent an unacceptable eyesore in
firearms of high quality, also in terms of aesthetics, and which
must thus be taken away during a subsequent finishing step.
[0009] This represents one of the main drawbacks of the
construction of a stock for a firearm in two half-shells, then
integral with each other, above all in the case of high aesthetic
quality firearms.
[0010] The purpose of the present invention is that of realising a
stock for a firearm with complex geometry, minimum weight and good
structural resistance.
[0011] Another purpose of the present invention is that of
realising a stock for a firearm which achieves an excellent
aesthetic result.
[0012] Another purpose of the present invention is that of
realising a particularly simple and function stock, with low
costs.
[0013] These purposes according to the present invention are
accomplished by realising a stock as outlined in claim 1.
[0014] Further characteristics of a stock are the object of the
dependent claims.
[0015] The characteristics and advantages of a stock for a firearm
according to the present invention shall become clearer from the
following description, given as an example and not for limiting
purposes, referring to the attached schematic drawings, in
which:
[0016] FIG. 1 is a perspective view of a stock for a firearm,
object of the present invention, realised in two half-shells;
[0017] FIGS. 2 and 3 are perspective views of the two half-shells
of FIG. 1;
[0018] FIG. 4 is an elevation view of a stock for a firearm
according to the invention;
[0019] FIG. 5 shows a detail of the left half-shell sectioned
according to the line V-V of FIG. 4;
[0020] FIGS. 6 and 7 are section views according to the line V-V of
FIG. 4 which show a detail of the joining edges of the two
half-shells connected together respectively before and after the
application of a cord of polymeric material in a throat between
such joining edges.
[0021] With reference to the figures, a stock for a firearm is
shown, wholly indicated with 10, comprising two half-shells 12, a
left half-shell 12A and a right half-shell 12B, suitable for being
connected together in a middle joining plane 13 to form the final
outer geometry of the stock 10.
[0022] The two half-shells 12, shown in FIGS. 2 and 3, are moulded
in polymeric material, for example through an injection procedure,
according to techniques known to men skilled in the art.
[0023] Each half-shell 12 is shaped externally according to the
desired final geometry and is equipped on the inner side with ribs
14, or local strengtheners, suitable for ensuring the required
resistance without substantially influencing the weight or external
geometry.
[0024] The two half-shells 12A and 12B are also equipped, along
their perimeter, with joining edges 15, which can extend along the
entire perimeter of the stock 10 or can only involve some portions
of it, as represented as an example in FIGS. 2 and 4.
[0025] Each joining edge 15, seen in section, has a flat portion
16, suitable for being welded to the flat portion 16 of the joining
edge 15 of the interfacing and mirroring shell 12.
[0026] On the outside of the flat portion 16, each joining edge 15
is equipped with a groove 17, which extends parallel and adjacent
to the flat portion 16, and identifies a thin outer lip 18, the
vertex of which is not arranged in the joining plane 13, but rather
goes inwards with respect to it (FIG. 5).
[0027] To assemble the stock 10, object of the present invention,
the two half-shells 12 are initially brought together and then
joined and made integral with each other, for example through a
welding operation carried out on the flat portions 16 of the
joining edges 15, or for example through gluing.
[0028] In a preferred embodiment, the half-shells 12 are joined
through a welding operation carried out according to known
methods.
[0029] When the half-shells 12 of the stock 10, object of the
present invention, are connected together, the interfacing lips 18
do not touch, but define a slit 19 for access to a dovetailing
perimetric throat 20, which extends along all of the joining edge
15 and is formed from the interfacing grooves 17 (FIG. 6).
[0030] In the throat 20 polymeric material, for example rubber
material, can be applied, deposited or injected, forming a cord 21,
which hides the joining edges 15 and the welding burrs and gives
softness to the touch, as well as an excellent aesthetic result
(FIG. 7).
[0031] In particular, the rubber material can be applied after the
welding of the half-shells 12A and 12B or else the cord 21 can be
positioned in the groove 17 of one of the half-shells 12A or 12B
before carrying out the welding.
[0032] The stock for a firearm, object of the present invention,
has the advantage of consisting of two shells of polymeric material
which are light and shaped according to whatever geometry.
[0033] The interfacing lips which are separated only by a thin slit
advantageously hide the welding burrs from view, even without the
application of the cord of rubber.
[0034] Moreover, the joining edges are advantageously hidden by a
cord of material, a detail which, as well as giving a pleasant
aesthetic result, also realises a shock-absorbing edge which
reduces the risk of scratches and scorings.
