DETAILED DESCRIPTION
[0022] In the description and the claims, the terms “front,” “rear,” “above,” “below” and so on are used in the generally accepted form and with reference to the object in its usual use position. This means that, for the weapon, the muzzle of the barrel is at the “front,” that the bolt or bolt carrier group is moved “rearward” by the explosive gas, etc. Transverse to a direction substantially means a direction rotated by 90° .
[0023] The charging handle assembly of the present disclosure can have any combination of the following features: [0024] the charging handle has two handles which are mounted on a charging handle assembly body so as to be rotatable about pins; [0025] the handles are pushed about the pins into their idle position by at least one handle spring; [0026] at least one handle has a gate-like control surface which, when moving into the work position, deflects a control element fixed to the housing in order to release a displacement of the charging handle assembly body along the weapon median plane; [0027] the control element is designed to be resiliently deflectable between a locking position and a release position; [0028] the charging handle assembly body comprises a mating protrusion for interaction with the handle, in particular a control surface formed on the handle and/or a deflection stop; [0029] the charging handle assembly body is mounted on or in a charging handle carriage which is arranged axially in front of the bolt carrier and is movable in the axial direction; [0030] the charging handle assembly body is mounted in the charging handle carriage so as to be displaceable normal (i.e., perpendicular) to the weapon median plane; [0031] the charging handle assembly body is held in the charging handle carriage by a locking mechanism; [0032] the charging handle assembly body has a locking recess for interaction with the spring-preloaded locking mechanism which is formed on the charging handle carriage; [0033] at least one handle has a recoil spring entraining device which is designed to protrude on the handle in order to interact with the recoil spring assembly in the work position and grip it temporarily; [0034] if there is contact between the charging handle carriage and the bolt carrier, when the handle is actuated into the work position the recoil spring entraining device engages in a recess in the recoil spring assembly, for example in a casing of the recoil spring, which corresponds to a forward position; [0035] in the foremost position of the charging handle carriage, the recoil spring entraining device is pivoted out of the recess in the recoil spring by returning the handle to the idle position.
[0036] Selected embodiments of the present disclosure, in particular those that facilitate the use, and in particular the pushing forward of the charging handle, may include any combination of the following features: [0037] the orientation of the slot holes for the pins attached to the charging handle assembly body, i.e. the slot hole direction, extend in the unfolded position, i.e. the work position of the handles, normal to the barrel axis or weapon median plane; [0038] when the relevant handle is pushed forward in the work position, a portion of its contour, preferably the control surface, abuts a contact region of the charging handle assembly body and/or a mating protrusion and prevents folding into the idle position; [0039] the handle has a control surface which is arcuate in plan view and can be supported in the work position on the mating protrusion in the direction of the weapon median plane; [0040] the control surface has a ramp or gate shape which rises along the arch shape in order to cause the control element fixed to the housing to be pushed in the vertical direction when the handle is actuated into the work position; [0041] at least one handle has a slot hole with a slot opening; [0042] at least one handle has a hook which substantially surrounds the slot hole and is formed up to the slot opening.
[0043] The arrangement according to the present disclosure of a slot hole on the handle and its mounting about pins allows a limited deflection between an idle position and a work position. The pin can be mounted after the handle is pushed onto the charging handle assembly body or, in a special embodiment with an open slot hole, the pin can also be integrally formed on the charging handle assembly body and mounting is carried out by pushing the handle on, as explained below. The deflection between the idle and work position made possible by the slot hole in any case also allows the handle to be displaced within limits, which allows a temporary locking effect of the handle to reciprocate the recoil spring assembly and/or to mount the handle without tools.
[0044] In a preferred embodiment, the slot hole has a slot hole direction which, in the idle position of the handle, is formed at an opening angle of from 5° to 85°, preferably between 20° and 70°, relative to the weapon median plane. As a result, when the handle is actuated forward, i.e. when the bolt is closed manually, there is an effective force transmission from the handle to the pin and thus to the charging handle assembly body.
[0045] Furthermore, it can be advantageous that, in a work position of the handle, the slot hole direction is normal (perpendicular) to the weapon median plane. This also allows effective force transmission to the charging handle assembly body when the handle is actuated in the work position - regardless of the selected shape of the handle.
[0046] At least one handle spring may be arranged on the charging handle assembly body in order to push the handle or handles into the idle position. The handle spring can be designed as a spiral, leaf or preferably as a bow spring, as a result of which somewhat more complicated geometries are possible, and the total number of required components can be reduced. In particular, it is advantageous to arrange only one handle spring on the charging handle assembly body for preloading both handles in the direction of their idle position.
[0047] To interact with the handle, or also a control surface formed thereon, it has proven advantageous to provide a mating protrusion on the charging handle assembly body. This mating protrusion can serve as a stop for a deflection stop of the handle and/or as a central contact surface for the handle in the direction of the weapon median plane in the work position. In this way, a locking effect can be generated for the handle in the work position and a lateral displacement of the handle is avoided.
[0048] In a further embodiment, an above-mentioned deflection stop can be arranged on the handle in such a way that inadvertent “over-deflection” of the handle beyond the work position is blocked, since the deflection stop is supported on the charging handle assembly body and/or the mating protrusion.
[0049] It has proven to be particularly advantageous if an imaginary extension of the deflection stop extends in parallel with the slot hole direction of the relevant handle. The deflection stop can be designed as a protrusion or as a step. An imaginary axis through the deflection stop or also along the step is particularly preferably designed to be aligned with the slot hole direction. This allows a very slim and thus weight-saving design.
[0050] In order to prevent the charging handle assembly from going along with the bolt carrier each time a shot is fired, a control element can be provided on or in the upper receiver of the rifle. Said control element can interact with the charging handle assembly body in such a way that it controls a locking effect or also a release of the charging handle assembly in parallel with the barrel direction. The actuation, i.e. the “activation,” of the control element takes place via a functionally complementary control surface on the handle. The control element can be preloaded in the vertical direction as a lock by means of spring elements, or it can already be designed integrally as a resilient control element, for example as a leaf spring. The control surface on the handle has a bevel which, when the handle is rotated, deflects the control element in the vertical direction and thus allows the charging handle assembly to be displaced in the barrel direction. Such a combination of the control surface and control element allows a significant reduction in components and relatively simple operation.
[0051] In order to further facilitate the operation and mounting of the handle, in a special embodiment a slot opening of the slot hole can also be provided which allows the handle to be pushed on over the pins.
[0052] In a particularly preferred embodiment, the handle has a hook which extends around the slot hole. This hook-shaped protrusion allows the handle spring to be pushed in the mounting position and thus serves to increase user-friendliness.
[0053] Furthermore, a locking recess can be provided on the charging handle assembly body, which, with a spring-preloaded locking mechanism, allows automatic locking in the installation position of the charging handle assembly body in the charging handle carriage. As a result, even when the weapon is otherwise assembled, the charging handle assembly body can be pushed laterally into a charging handle assembly seat of the charging handle carriage provided for this purpose. This allows a very high level of operator comfort and very quick actuation or mounting of the charging handle assembly.
[0054] The shape of the handles on the charging handle assembly body can be adapted to the respective requirements by a person skilled in the art, or even the shooter, with knowledge of the present disclosure. In particular, the design of the actuation surfaces or the shape of the handles can be optimized in advance by the mounting (or removal) according to the present disclosure by means of a slot hole that is partially open to the outside and can be relatively easily adapted by the shooter to the particular situation. Thus, for example, it is possible to vary between handles of different lengths and shapes, or even a “dummy handle” or cover grip on one side, thus achieving high versatility of the charging handle assembly.
[0055] At this point, reference should be made to the content of the as yet unpublished European patent application EP19201448, in which a very similar principle for a charging handle is disclosed.
[0056] As can be seen from
[0057] All of these parts do not always have to be present, or their design can vary slightly depending on the application, such as in hunting weapons, but on the other hand other parts can also be added, for example mounting elements for riflescopes, for laser pointers, and the like. It is also possible for some of said components to be inseparably formed together on a more complex component, such as the lower receiver 10 in the case shown, and so the illustration is only one example of a highly modular rifle.
[0058] With the aid of the following illustration, and on the basis of several preferred embodiments of the charging handle assembly 8 according to the present disclosure, the structure and sub-functions of this assembly will be presented by way of example in sections.
[0059] Basic function of the charging handle assembly 8:

Lateral Installation of the Charging Handle Assembly 8:
[0063] Looking at
[0064] From the exploded view of
Form and Function of an Exemplary Handle 21:
[0065]
[0066] A closed slot hole 36 is also technically possible, but the following advantages with regard to the particularly simple mounting/removal do not apply since the handles 21 would first have to be placed on the charging handle assembly body 20 and fixed in their position by means of the pins 23.
Mounting/removal process:

[0069] As can also be seen from
Locking effect of the control element 29 and function of the control surface 22:
[0070] The locking effect of the control element 29 against undesired movement of the charging handle assembly 8 when the shot is fired can be carried out in a simplified manner as follows. As can be seen clearly in
[0071] If the handle 21 is then pivoted into the work position, the control surface 22 which is formed on the upper side of the handle 21 and rises in the manner of a ramp or gate causes a vertical deflection of the control element 29, as can be clearly seen from
Manual Closing Movement (Forward Assist):
[0072] The charging handle assembly 8 according to the present disclosure can also be used for the manual closing movement; see the sequence diagrams in
[0073] In a preferred embodiment, the handle 21 has a deflection stop 41. The deflection stop 41 can be seen very clearly in
[0074] It was also found to be advantageous for the orientation of the slot hole direction 33 to largely coincide with the longitudinal extent of the deflection stop 41, or even to be in alignment therewith. This relationship is particularly clear in
[0075] Furthermore,
[0076] Terms such as the “lower region” of a component or device or, more generally, an object, refer to the lower half and in particular the lower quarter of the overall height; “lowermost region” refers to the lowermost quarter and in particular an even smaller part, while “central region” refers to the central third of the overall height (or width—length). All these terms have their generally accepted meaning, applied to the intended position of the object under consideration.
[0077] In the description and the claims, “substantially” means a deviation of up to 10% of the stated value, if physically possible, both downward and upward, otherwise only in the appropriate direction; in the case of degrees (angle and temperature), this means ±10°.
[0078] With terms such as “a spring,” the word “a” is not to be considered to represent a singular numeral, but rather is to be considered an indefinite article or pronoun, unless the context indicates otherwise.
[0079] The term “combination” or “combinations” means, unless stated otherwise, all types of combinations, starting from two of the relevant components up to a large number or even all of such components; the term “containing” also means “consisting of.” Statements such as “more than three” include and disclose any individual number greater than three.
[0080] The features and variants stated in the individual embodiments and examples can easily be combined with those of the other examples and embodiments and in particular can be used for characterizing the disclosed charging handle in the claims without necessarily including the other details of the particular embodiment or of the particular example.
[0081] In conclusion, the following is established: The invention relates to a rifle with a weapon median plane 32, comprising a barrel 1 with a barrel direction/axis 37, a gas drive 2, a bolt carrier 18, a recoil spring assembly 31 and a charging handle assembly 8 arranged in front of the bolt carrier 18, with handles 21a,b rotatably mounted about pins 23a,b being pushed into their idle position by at least one handle spring 24b. By forming a slot hole 36 on the handle 21, the charging handle assembly body 20 can be displaced in both the pulling and the pushing direction in or counter to the barrel direction/axis 37. By optimizing the design of the handle 21 or the orientation of at least the slot hole 36, the deflection of the handle 21 in the lateral direction can easily be optimized for various applications by a person skilled in the art.
[0082] The charging handle assembly 8 according to the invention is mounted on a carriage 19 which is arranged axially in front of the bolt carrier 18 and is movable in the axial direction, and said assembly and can be pushed in or removed from the side relatively easily.
