Description
[0015] Further characteristics and advantages will become better apparent from the description of preferred but not exclusive embodiments of the invention, illustrated by way of non-limiting example in the accompanying drawings, wherein:

[0029] With reference to the cited figures, the stock with interchangeable cheek rest according to the invention, globally designated by the reference numeral 100, includes a main body 2 and a cheek rest 1 detachably associated thereto.
[0030] According to the present invention, the cheek rest 1 is interchangeable and is associated with the main body 2 by means of a quick coupling.
[0031] The cheek rest 1 includes a supporting structure, globally designated by the reference numeral 3, and a cheek pad 4, which rests against an elastic member 5 associated with the structure 3.
[0032] Advantageously, the cheek resting pad 4 is made of soft material, such as a gel or polyurethane.
[0033] The elastic member 5 is easily removable to be replaced with another member having different elastic characteristics.
[0034] The elastic member 5 is advantageously constituted by a leaf spring, which can be inserted and removed from the structure 3 when the cheek rest 1 is separated from the body of the stock 2.
[0035] According to the present invention, the leaf spring 5 is an elastic blade, which has a first end 51 that can be engaged in a seat 6 formed in the structure 3 of the cheek rest, and a second end 52 that is adapted to abut against an abutment member 7 formed in the structure 3 in a position that is opposite to the position of the seat 6.
[0036]
[0037] If one wishes to vary the resting characteristics of the cheek rest, it is possible to replace the leaf spring 5 with another one having different elastic characteristics.
[0038] Replacement of the leaf spring 5 is performed by extracting the spring from the seat 6, as can be seen in
[0039] The assembly of the leaf spring 5 in the structure 3 occurs by operating in reverse.
[0040] Replacement of the leaf spring 5 can occur when the cheek rest 1 is separated from the body of the stock 2.
[0041] According to the present invention, the cheek rest 1 is interchangeable and is associated with the main body 2 by means of a quick coupling system.
[0042] The quick coupling system for coupling the cheek rest 1 to the body of the stock 2 includes a front tooth, which is constituted by the abutment member 7 described above, which can be inserted in a front recess, not visible in the figures, which is formed in the body of the stock 2 at a front edge 81 of an open region 8 that is formed in the body of the stock 2 and is adapted to accommodate the cheek rest 1.
[0043] According to a first aspect of the invention, the quick coupling system further includes a mushroom head 11 that is formed in the rear region of the structure 3 of the cheek rest 1, i.e., in a region that is substantially opposite the position of the abutment member 7.
[0044] The head 11 may also have any other appropriately contoured shape.
[0045] The mushroom head 11 protrudes downwards from the structure 3 and can be inserted in a hole that is formed proximate to a rear edge 82 of the open region 8 that is formed in the body of the stock 2 and is adapted to accommodate the cheek rest 1.
[0046] The insertion of the mushroom head 11 in the hole of the rear edge 82 occurs by snap action due to the presence of elastic members, constituted by a hairpin-shaped spring 15, as can be seen in
[0047] The cheek rest 1 is associated with the body of the stock 2 by inserting the abutment member 7 in the front recess formed in the body of the stock 2 at the front edge 81 and by then pressing the cheek rest 1 against the body of the stock 2 so that the mushroom head 11 is inserted in the hole of the rear edge 82, engaging the hairpin spring 15, which locks by snap action the mushroom head 11, locking the cheek rest 1 in position.
[0048] In the locking system having the hairpin spring 15, shown in
[0049] The snap acting engagement system described above is advantageously of the type described in EP1396697.
[0050] According to a further aspect of the invention, shown in
[0051] The small plate 17 is provided with a fork-shaped front part 171 in order to allow coupling to the mushroom head 11 of the structure 3 of the cheek rest 1.
[0052] A rear part 172 of the small plate 17 is conveniently shaped to allow easy grip and handling of the small plate on the part of the user.
[0053] The small plate 17 also has at least one slot 173 which engages protrusions 33 and 34, formed in the structure 3, acting as a stroke limiter and retention of the small plate 17.
[0054] The small plate 17 is made to slide between a locked position, visible in
[0055] The cheek rest 1 can be assembled-disassembled even without tools.
[0056] Preferably, the structure 3 also includes a pair of hooks 10, formed on the sides of the structure and adapted to engage respective lateral seats 13 formed on the lateral edges of the open region 8 of the body of the stock 2.
[0057] The cheek rest 1 can be easily mounted on the body of the stock 2 by inserting the abutment member 7 in the front recess, formed in the body of the stock 2, and simultaneously the lateral teeth 10 in the respective lateral seats 13, formed on the lateral edges of the open region 8 of the body of the stock 2, making the cheek rest perform a combined rotary and translational motion and finally pressing at the rear in order to engage by snap action the mushroom head 11 in the hole formed near the rear edge 82 of the open region 8 in which the cheek rest engages.
[0058] In practice it has been found that the invention achieves the intended aim and objects, a stock with interchangeable cheek rest having been provided which is constructively simple and at the same time extremely functional.
[0059] The stock with interchangeable cheek rest according to the present invention ensures high comfort by virtue of the fact that the surface covered by the soft material in the face resting region is very large and this allows soft resting in all firing positions, which vary as a function of the style of each individual shooter.
[0060] The aspect of absorbing recoil and the vibrations toward the face is fundamental, especially for shooters that produce large fire volumes with cartridges of considerable weight, for example in duck hunting, etc.
[0061] A further advantage of the present invention resides in the possibility to vary the elastic characteristics of the cheek rest, since the leaf spring can be replaced easily and rapidly with leaf springs having different elastic characteristics.
[0062] The cheek rest can in fact be marketed with multiple springs having different rigidity, by virtue of their low cost, so that the shooter can choose the most suitable one according to his requirements.
[0063] Another advantage of the present invention is the modularity of the stock and cheek rest assembly. The cheek rest can be disassembled easily from the stock and can be replaced with or without tools and this allows to replace the original cheek rest with cheek rests of different heights or different shapes or different hardnesses.
[0064] The materials used, as well as the dimensions, may of course be any according to the requirements and the state of the art.
[0065] This application claims the priority of Italian Patent Application No. UB2016A001190 (corresponding to No. 102016000021445), filed on 1 Mar. 2016, the subject matter of which is incorporated herein by reference.
