Description

Weapon Grip Assembly {WEAPON GRIP ASSEMBLY}

The present invention relates generally to an inorganic grip assembly, and more particularly to an inorganic grip assembly for supporting the weapon or weapon system from the front.

The invention claims priority under International Application No. PCT / US03 / 35601 with an international application date of 6 November 2003 under 35 U.S.C. 363, and further discloses provisional application 60 / 492,509 with an application date of August 5, 2003 to U.S.C. Under U.S.C. It is a formal application under 111 (a).

It is fundamentally applied to weapons with barrels for loading ammunition, mounted close to the trigger, and more specifically "pistol grip". Pistol grips in a wide variety of shapes or configurations are known and should be considered functionally and ergonomically.

The "long" in the barrel of the weapon is supported in front of the rifle, for example in the form of a barrel handle or similarly located above the end of the handle (located at the bottom of the front of the weapon) and connected. For example, the origin and evolution of weapon systems in tactical weapons is quite different from the function of "weapons." Challenges continued to require shape diversification to avoid constant neutralizer system failures.

Many of the support and law enforcement departments are accompanied by tactical weapon systems, including a variety of "supplemental devices", for example "host weapons" (eg, rifles) to be mounted on or mounted on a 40mm grenade launcher. These main weapons are in the form of various rails, interbars, or rail systems, upper and lower receptacles and / or handle components, butts or other accessories sometimes referred to in unit weapon systems, etc. (E.g., location, lighting, catapult attachments, anchors, etc.) Traditionally, weapon system accessories prepare items for the rails to be aggregated in the rail system by a constant producer and each producer of unit weapon systems. Nevertheless, the rifle grips, however, are "one size fits" for front-mounting various types of weapon systems. It can be seen that commercially available aggregates consisting of an inorganic assembly of various end rail systems or more specific rails are possible, allowing the form to be applied to the weapon so that more various functions are excluded.

For example, the weapon system consists of a main weapon (e.g. rifle) and an additional device (e.g. chute launcher) which is a launcher coupled to the rifle to be positioned in the front half of the rifle under the rifle's barrel. The position has become the world's army standard since the introduction of a grenade launcher connected to the rifle approximately 40 years ago.

By the way, the method of attaching the launcher of the main rifle described above may be the most special answer for the aggregation of the devices to be separated. This does not provide the user with the best answer for the operation or transport of the launcher or rifle when the two devices are combined.

To carry or operate a weapon system in which a rifle and launcher are combined, the operator's hand holds the pistol grip of the rifle adjacent to the life trigger to hold and / or operate the device and to maintain the system in the selected position. Above, with the other hand below the launcher, at the front end of the weapon system. The right hand, typically used to support the rear end of the rifle in the piston grip, uses the pointing finger to partially wrap around the pistol that causes the operator to close the finger around it and to fire the rifle. The left hand, typically used to support the front end of the rifle, holds a cup or candle in the palm of the hand and thumb partially wrapped around the launcher handguard to support the weight of the rifle and launcher combination and control the direction in all axes. Is positioned below the grenade launcher.

Since the ribbed handguard of the 40 mm launcher barrel is not secured to the operator's hand in any other way, it needs to be placed on the palm of the operator's left hand. Since the barrel is located under the launcher receiver, the hand restraints cannot wrap and wrap around the barrel completely, making it impossible for the operator to wrap around the barrel with his hand and hold it firmly. This results in a weaker control of the weapon system and also results in increased operator fatigue due to the inherent hand position and orientation for the weapon system, and more particularly for the launcher.

The radius of the launcher hand support is greater than 2.25 inches, which is 50% greater than the optimal grip radius for a user with an average hand size to grab objects around his fingers and at least one finger behind his thumb. . The size of the launcher barrel hand support is not intended to provide the best grip surface, but rather to accommodate a 40 mm barrel.

Since the center of gravity of the rifle gun has been shifted by the addition of the launcher, the operator now has the knowledge that the rifle gun / launcher combination is heavy on the front and that the diameter and orientation of the hand support are controlled by the launcher's functional characteristics. For both non-operators, such weapon system combinations are highly desirable in their specifications, but are difficult to control and tired to transport or operate, primarily because hand position and orientation are required. The only solution for the operator to relieve such fatigue and to provide additional control over the system is to change the way the operator holds the launcher.

There are many difficulties in developing to hold the launcher in a better way. In order to provide the operator with maximum comfort, effectiveness and efficiency, only the operator's hand position should be changed, not the area in which the launcher is controlled. The only way to change the hand position as required to secure the launcher is to add a gripping device. Adding any element, assembly, or means to the 40 mm grenade launcher barrel presents a number of problems, some of which are discussed below.

First, the M203 40 mm barrel hand support is the point where the operator puts his hand and is primarily made of thin plastic material. Very little when fired through the M203 barrel, but because heat is generated, the hand restraint is particularly required to have a thermal insulation function.

Secondly, the M203 40 mm hand restraint surface is obstructed by two cartridge retainer rivets and one hand rest set rivet. Such a structure should be considered in the solution to the problem of attachment.

Third, the M203 40mm barrel has a thin wall, eliminating the use of fasteners that partially pass through the barrel wall. In fact, the barrel hand support is adhesively attached to the barrel because the barrel wall prevents the use of fasteners. In addition, gun barrels of weapons are generally not drilled by fasteners because their primary function is to contain exploding gases. No solution is needed that requires a fastener to destroy the barrel wall. Furthermore, because of the thin wall of the barrel, no attachment is allowed that can twist the barrel by unevenly pressurizing it, and such a barrel cannot function properly.

Fourth, the barrel combination of the M203 is designed to be separated from the enclosure without the instrument. This makes it easy for the operator to clean up when the parts of the barrel are soiled with dust during launch. Since the barrel can be cleaned as a separate part, the remaining enclosure and rifle gun to which it is attached can be kept free from contamination during the cleaning process. Any grip attachment method that prevents or interferes with this barrel removal process is undesirable. Moreover, cleaning the barrel is a tedious task of using solvent to remove the barrel residue, and then to clean the barrel again to remove solvent residue. The barrel and hand rests may be contaminated and cleaned during this process from the outside. The hand support must be dry to allow the operator to grip the grip. During the cleaning process, if any grips must be attached on the barrel, this will also be another area to be cleaned and is therefore undesirable.

Fifth, the barrel can be removed from the enclosure so that the mechanic can repair it. If not removed, the barrel extension may not be reassessed or altered or the cartridge stator or cartridge stator spring may be repaired or repositioned. To perform this repair, the barrel is placed in a vise or other holder which, during repair, positions and supports the barrel assembly along the sides and on the bottom. Any manner of grip attachment presented in any of these areas would impair repair activity and is undesirable.

Finally, the hand support can be removed from the barrel to repair the spring in the cartridge or to replace the hand support itself. Any manner of grip attachment that is permanently fixed to the hand restraint prevents or disables such repair or replacement.

It is therefore highly desirable and advantageous to provide an inorganic grip assembly for supporting the front end of a weapon or weapon system, in particular a versatile inorganic grip assembly that can be detached to a 40 mm grenade launcher, having the following characteristics:

Commercially 'as ready-made', available and not requiring any development effort:

Fit to any M203 launcher currently in use and not requiring any modification;

-Small, lightweight and rugged;

Not permanently loaded onto the launcher barrel assembly;

The operator can be quickly attached and detached from the launcher hand support without tools;

Close contact with the barrel surface;

Not penetrating the barrel or hand support;

-Adjustablely positioned on the launcher to allow the operator to tailor size or comfort;

The operator can better control the weapon due to better grip, thereby helping and / or improving the firing accuracy of the weapon system (ie, rifle guns and launchers);

Not inhibit or prolong the repair activity of the launcher or rifle gun;

-Adding or not including additional considerations or limitations in the operation of the launcher or rifle gun;

Not requiring additional training of the operator in use;

Improving operator weapon control and thus stability;

To reduce operator fatigue by improving the method of operation and transport of the launcher and rifle guns;

Reducing the effort required to hold the barrel while in motion so that the operator can easily concentrate all the energy on the actions associated with opening / closing the launcher barrel;

Improve the mount and reload operations of the M203 and make them faster and more controlled, thus allowing the operator to get to the target on the next shot faster;

To make the operator safer and more efficient by increasing the firing speed and accuracy;

In the process of the operator holding the launcher and rifle, in damp, damp or snowy conditions, or while there are any other contaminants that make this behavior difficult while the current hand position requires holding the launcher hand restraint. To be able to hold it easily and securely; And

To allow the operator to easily or firmly hold the launcher and rifle when he or she wants to use the weapon during walks, canals or after Haga or other unexpected movements. This control enhancement makes the operator more effective and safer for others around him.

As weapon adaptability is an important consideration or factor for weapon users, the “Rail Adapter System” (RAS) has been a common aid in combat rifle guns, etc. Such systems have been used by many manufacturers. Because they are manufactured, there are many versions, see Knight's Armament Co.

Typically, the RAS is fitted (ie replaced) in place of the weapon hand restraint, and in the rifle guns at 3, 6, 9 and 12 o'clock positions relative to the weapon barrel, aids such as flashlights, thermal telescopes, etc. It is intended to provide a generic structure for coupling (ie receiving) lasers, or the like. Known systems cover the different rail lengths and integration techniques required to attach to the weapon. Some RASs consist of two assemblies, a first portion providing the rails in the 3, 9 and 12 o'clock positions, and a second portion providing the rails in / to the 6 o'clock position. It is desirable that the rail at the 6 o'clock position can be separated so that the grenade launcher can be mounted (ie instead of each structure occupying the same physical space and generally using the same attachment position for the weapon).

The RAS system was originally proposed by the US Army in 1998 to provide all suppliers with the same type of attachment point for the M-16 rifle. Between the oblique side edges of the rail (i.e., the side), the circumferential clock position for the rail relative to the weapon barrel, and the rails of the rail and their markings (i.e. B22, B28 are the bottom, T denotes the government) While specifying the spacing designation, the implementation of the solution (ie weapon integration strategy) was left to the contractors.

In addition to the aforementioned assistive devices (e.g., flashlights, telescopes, target aids, etc.), rail mounted grips (e.g., vertical shear grips) can be used to attach to the rails and are known to date The mounting grips are female mounting flanges which are slidably received on the rail of the RAS and then selectively engaged with a portion of the rail via, for example, a screw fastener which is coupled to or is tightened to press against the rail. Hold the grip here.

In the rail mounting grip presented by Knight's Armament Co., the joining studs are screwed into the holes on the shaft of the hand grip with the rail receiving flange. The engagement nail has an opposite free end, having a bottom (or hat end) that defines the lowest extreme to the instrument and a node (eg a centrally located protrusion) on its government surface. When sliding the grip along the rail and longitudinally on the rail through the flange, the joining nail protrudes upward relative to the grip so that the governmental node of the free end has many slots or spaced channels in the rail. (E.g., the knob is sized to be accommodated in any one of the slot or spaced channel). Thereafter, the coupling nail is further tightened to squeeze with the portion of the rail.

This structure is problematic because the nodes are prone to breakage and / or deformation and require the operator's attention to properly position the grips on the rails so that the nodes will actually fall into one of the many position slots. Already appeared. Since the raised positions between the slots and the slots of the rail have the same width, the operator initially has a 50-50 chance to recognize it correctly. If the position is incorrect, the grip will not be tightened.

Another problem with currently known rail mounted grips is that they are required to slide on the rail of the RAS from the front of the weapon (e.g., muzzle end) to the rear of the weapon (e.g. butt end). Known grips cannot slide toward the rear end of the rail because there is no gap between the rail end and the rifle enclosure to allow access to match the flange and the rail. This would be a decisive consideration if any other aids were mounted on the rail towards the grip. If the user wants to improve handling by detaching the grip from the weapon or moving it to another rail, much time is required to arrange or rearrange the weapon. Thus, providing a weapon grip that can be versatilely mounted on the rail of the RAS, and also a rail-mounted grip having a safety lock or engagement mechanism that can be easily operated, i.e. the slide engagement and / or engagement nails known to date. It is desirable to provide what is not adopted.

More preferred and advantageous are shear grips for inorganic or inorganic systems in a multifaceted, secure manner. For example, as implied above, inorganic grips having adaptability and convertibility to be accommodated by various known weapons or weapon system structures are particularly preferred, and more particularly, inorganic grips with clamping jaws are preferred. For example, weapon grips with replaceable or interchangeable jaws, which hold the grenade launcher barrel on the one hand, or the rail of the RAS on the other hand, are particularly advantageous.

Further features and advantages obtained in view of these features will become more apparent with reference to the drawings and detailed description of the invention.

A preferred weapon grip assembly of the invention is attached to the front of the weapon, for example a handguard, which is at least partially clamped to the handguard with two clamps (ie jaws) of the base assembly supported by the handle. By enclosing (ie tightening the part). The base assembly further includes a post (eg, threaded stud) with a clamp end adapted for each clamp to maintain pivot motion. As the mandrel is inserted between the handle and the clamp of the base assembly, the post of the base assembly is received in the hole of the handle. By rotating around the post of the base assembly, the upper free surface engages the clamp for pivoted closure around a portion of the weapon, to secure the weapon grip assembly as the base assembly is pulled into the handle, thereby The barrel receives or sits the clamp end of the post.

  The handle of the inorganic grip assembly includes a loading space accessible at its free end. A cap is further provided to seal the load space. The preferred weapon grip assembly further comprises a latching mechanism that reversibly secures the mandrel to the handle, such that the mandrel and handle rise above the post of the base assembly to actuate the clamp to "lock" around the weapon. (lock) "position. Preferably but not necessarily, the inorganic grip assembly further includes an alignment and retention mechanism for positioning and holding (ie orientingly uniting) the mandrel over the base assembly, more preferably its clamp end.

The alternate grip may be provided with an alternate clamping element to be alternately provided. In other words, the weapon grip can be switched quickly and easily to grasp the grenade launcher barrel, or the rails of the RAS. In the former case, each jaw is curved in its entirety to hold the launcher barrel, and each jaw has a surface that receives the rib of the barrel handguard (ie, a surface that engages the barrel). In the latter case, each jaw further comprises a profiled surface, more preferably a rail receiving surface for engaging the lateral edge of the rail of the RAS. The clamps are arranged such that the rails of the RAS can be captured or trapped, forming a rail receiving channel through which they can be pivoted.

As a preliminary description, the structure and features of the inorganic grip or grip assembly of the present invention attached to the inorganic system shown in FIG. 1 are shown generally in FIGS. 2 to 12. The functionality of the inorganic grip assembly of the present invention can be best understood with reference to FIGS. 5-9 and various relationships between the selection structure and / or subcomponent of the present invention and the weapon system, and also in the selection structure and / or subcomponent. Is clearly presented. Finally, another non-limiting embodiment of the inorganic grip assembly of the present invention is shown in Figures 13-16, more preferably an embodiment that highlights another interface between the base assembly and the handle (Figure 13); Another embodiment highlighting another handle latching mechanism (FIG. 14); And another embodiment (FIGS. 15 and 16) highlighting another clamp or jaw arrangement.

In Fig. 1, a preferred embodiment of the weapon grip assembly 16 of the present invention in combination with a representative weapon, that is, an attack weapon 18 (i.e., a weapon system), is shown throughout. In general, the inorganic grip assembly 16 of the present invention includes a base assembly 20 that extends or is supported by a handle 22. Base assembly 20 includes a clamp or jaw 24 adapted to engage the front portion of the weapon 18 (eg, the handguard of the front portion). More preferably, each clamp 24 preferably comprises an inorganic receiving surface 26. The grasping function of the clamp 24 of the base assembly 20 is performed by adjusting the handle 22 associated therewith. More preferably, the interaction between the handle 22 and the structure of the base assembly 20 allows the clamp 24 to be reversibly coupled to the front of the weapon 18. This will be explained later in more detail, in particular in FIGS. 5 to 9.

The weapon grip assembly 16 of FIG. 1 is representatively shown hanging from a grenade launcher 28, such as an M203 style 40 mm launcher. The weapon grip assembly 16 may optionally be positioned to attach to a ribbed barrel handguard 30 of the grenade launcher 28 to be suspended. In particular in light of the disclosure herein, it should be understood that the inorganic grip assembly of the present invention is not limited to being attached to a grenade launcher. The clamp of the inorganic grip assembly of the present invention is generally intended to be secured to the front of the weapon or weapon system, and the base assembly is particularly advantageous in the context of the securing function of the inorganic grip assembly of the present invention.

Advantageously, the weapon grip assembly of the present invention is designed to be attached to the front of a weapon, such as a handguard, to support it forward. It is particularly desirable to provide a weapon grip assembly that can easily support a weapon such as a rifle from the front, as well as weapons with additional devices (eg, grenade launchers), with little or no modification. It may be widely used in legislation or military personnel.

2 and 3, in particular 4, a preferred embodiment of the inorganic grip assembly 16 of the present invention comprises a base assembly 20 extending from the handle or entirely supported by the handle 22 and the base assembly ( A mandrel or collar 32 inserted between the portion of 20 and the handle 22. Preferably but not necessarily (see the device of FIGS. 13 and 14), the inorganic grip assembly 16 of the present invention provides an alignment and retention mechanism for positioning and holding the mandrel 32 over the base assembly 20. A latching mechanism 36 further comprising a retention mechanism 34 (i.e. a retainer), and also preferably but not necessarily, detachably secures the handle 22 to the mandrel 32. FIG. mechanism) to determine the spatial relationship between the handle 22 and the base assembly 20. This will be explained later.

The base assembly 20 of the inorganic grip assembly 16 of the present invention has a clamp or jaw 24 adapted to engage the front portion of the weapon and a clamp end 40 adapted to hold the clamp 24. And post 38 (FIG. 4). The clamp 24 is held or fixed to the clamp end 40 of the post 38 for pivotal movement against it, and more preferably, individually deflected to easily receive the front of the weapon system (ie, weapon grip assembly). Has a ready state to be attached to the weapon, i. The components of the base assembly, ie clamp 24 and post 38, are preferably made of aluminum and hard-coated anodized to black.

Each clamp 24 of the base assembly 20 is generally free of the inorganic receiving surface 26 opposite the outer surface 42 and opposing ends, ie opposite the base end 46. It has a free end 44. As best shown in FIG. 4, the base end 46 of each clamp 24 is preferably adapted (ie, hinged) for pivotal movement (eg, hinge engagement) on the clamp end 40 of the post 38. The distance between the free ends 44 of the clamp 24 is not fixed, ie there is a range of movement between the free ends 44 of the clamp 24). The base end 46 of each clamp 24 preferably has a lobe-like configuration, ie, a surplus on the outer surface of the clamp: the base end 46 is external to the clamp 24. It has a local outer surface that extends or protrudes beyond a radius contour (more preferably, an outline or contour associated with outer surface 42). See FIGS. 4 and 5/6.

Each lobe 48 (ie, locally thick or terminus) of the base end 46 of the clamp 24 comprises a through hole 50 for receiving the pin 52, which pin The clamp 24 is secured to the post 38 across the opposing upright wall portion 54 of the clamp end 40 of the post 38 through a set of paired through holes 53 in series.

The pins 52 and pinholes 50, 53 are not inserted into the pin 52 from one side of the clamp end 40 of the post 38 but still positioned by an interference fit on the other side. It is characteristically designed to be fixed.

This assembly method allows for field replacement of a clamp that can be damaged, while avoiding a screw-type fastener that can become loose. The pins are coated with a strong steel material to prevent corrosion.

The clamp pins 52 are adapted to the pivot axis of each clamp 24, the clamp 24 controlled by the mandrel 32, in response to the geometry and configuration of the clasped arms. It defines the range of pivotal movement, ie the interrelationships and interactions (e.g., handle 22 / base assembly 20) between the components of the weapon grip assembly of the present invention. Essentially the excess material near the pivot axis, the lobe shape of the base end 46 of the clamp 24 ensures structural integrity near the clamp through hole 50 for long term reliable pivoting. do

As mentioned above, in promoting the ease of receiving and holding portions of the weapon system, the fixed state of the weapon grip assembly 16 advantageously brings the jaw 24 of the base assembly 20 into an “open” state. Position (eg, biases) (FIG. 5). The compression spring 56 for each clamp 24 is from the outer surface of the lobe 48 of the base end 46 and from the opposing upright wall portion 54 of the clamp end 40 of the post 38. It is positioned to be inserted between the extending surfaces 58 (ie the “floor” of the clamp receiving “space”, see FIGS. 4 and 5/6). In the stationary state of the inorganic grip assembly (FIG. 5), the springs 56 bias each clamp 24 (ie, apply a force to the base end 46 of the clamp 24), and thus clamp 24. ) "Opens" in preparation for grabbing part of the weapon. The biasing effect of the spring 56 on the clamp is applied to the mandrel 32 until the point at which the spring 56 is compressed and the free end 44 of the clamp 24 is secured to the weapon 18. Thereby invalidating or more globally adjusting. This will be explained later.

Another advantageous feature of the present invention is that the clamp 24 is not open enough to allow the opening spring 56 to come loose. This is due to the special relationship between the clamp end pin hole 53, the clamp pin hole 50, the position of the spring hole 60, the length of the spring 56 and the height of the side wall of the clamp end 40 of the post 38. . Another functionality of the spring 56 is to eliminate the rattling that may be caused by the operator carrying the weapon grip assembly without moving the clamp to the fully closed position manually. As should be easily understood, excessive noise at the moment of crisis can endanger the operator.

The free end 44 of each clamp 24 has a contoured tip 62, preferably but not necessarily, that is, the tip 62 of the free end 44 is not square or Squared. Rather than having a single flat surface that connects or couples the outer surface 44 and the inorganic receiving surface 26, the inorganic receiving surface 26 of the free surface 44 and the flat surface extending from the outer surface 42 are approximately 90 degrees. Unite at an angle to define a free cross section or tip 62. This clamp tip arrangement allows each clamp 24 to engage the upper end of the handguard 30 (e.g., vertical lip 64) to prevent circumferential movement around the launcher handguard 30, but the calculated amount of exercise The advantage is to accommodate the original manufacturing tolerances of the handguard. As well as debris infiltration.

Each clamp 24 of the base assembly 20 is preferably curved throughout its length, i.e. between the base end 46 and the free end 44, in promoting clamping. The weapon receiving surface 26 of each clamp 24 is adapted to cooperatively engage (eg, receive or settle) the outer surface of the handguard 30 of the weapon front (FIG. 9). For example, in the situation of being accommodated above the grenade launcher 28 of FIG. 1, the weapon receiving surface 26 is provided with a concave segment to receive or settle the rib 68 of the barrel handguard 30. 66, more preferably, a radial groove.

Although the "flats" 70 of the handguard 30 are intuitively desirable for the reception of grips or handles, the ribs 68 may be adapted to the full barrel of the launcher barrel 72 in full indexing and 90 ° alignment. Provide the longitudinal axis. Among other things, the radiused groove 66 of the weapon receiving surface 26 facilitates the operator in maintaining the selection position, allowing the operator to make a special rib position selection on the handle placement handguard relative to the weapon grip assembly, The weapon grip assembly helps to withstand full rearward movement when pulling or pushing on it while operating or holding it.

Each clamp 24 includes a radiused recess 74 above its midpoint length and along its short axis (ie, located closer to the free end 44 than the base end 46 of the clamp 24). The radiused recess 74 effectively crosses (ie crosses laterally) the weapon receiving surface 26 from one end to the other end. Depending on the handguard maker, the rivet 76 (FIG. 5) of the locator disk (not shown) may be remarkably protruding from the launcher barrel 72. The radiused recess 74 of the weapon receiving surface 26 allows the clamp 24 of the base assembly 20 to be positioned on top of or above the rivet 76 without considering its protrusion, thereby selecting a location for the launcher. It does not limit

As mentioned above, the base assembly 20 also includes a post or stud 38, among other things, to support the clamp of the base assembly 20. At least part of the post 38 is threaded into the handle 22. As demonstrated with reference to FIG. 4, more preferably, the threaded portion of the post 38, as well as the entire base assembly 20, is directed towards or into the handle 22.

It is particularly advantageous for the proper functioning of the device that the clamp 24 and the clamp end 40 of the post 38 fit completely into the handguard 30. The more perfect the fit, the less pressure it will take to hold the grip assembly in place. In promoting this, the upstanding wall portion 54 of the clamp end 40 of the post 38 (ie, the wall inserted between the clamps 24 for pivotal support, FIG. 4) is contoured (eg, Inclined) top end 78 (ie, barrel rib contact surface, see FIG. 7). The upper end 78 of each upstanding wall portion 54, more preferably the outer upper end, is in contact with the portion of the rib 80 near the rib 81 seized by the clamp or jaw 24. Is converted. The aforementioned structural features prevent the front and rear release of the inorganic grip assembly 16 but allow only a small amount of vibration under high pressure to push and pull.

The mandrel or collar 32 of the inorganic grip assembly 16 of the present invention makes the handle 22 one with the base assembly 20, ie the clamp end 40 and the clamp 24 of the post 38. It is positioned to engage or receive. In promoting this, the mandrel 32 preferably has an upper portion 84 and a lower portion 86, the lower portion 86 is received or seated above the top of the handle 22, and the lower portion 84 is a post ( Clamp end 40 of 38 is received or settled to engage clamp 24. The mandrel 32 is entirely received on the post 38 of the base assembly 20 (see FIGS. 4 and 5), and “rides” the handle “up” the post 38 of the base assembly. This will be described in detail later with reference to FIGS. 5 and 6. The mandrel 32 is preferably made of aluminum and hard-coated in black.

Structurally, the top 84 of the mandrel 32 includes at least one set of pairs of walls 88 facing each other, with a “floor” extending between the first walls for discussion (ie, Wall 88 extends upwards from the floor 90). 13, 14, the upper portion 84 of the mandrel 32 further includes a pair of opposite walls, ie a second wall 92. The floor 90 further includes through holes or holes for receiving the posts 38 of the base assembly 20. Coupled with upstanding walls 88 and 92 to effectively "house" the clamp end of post 38 to protect pivot linkage of post 38 and clamp 24 (FIG. 2 or 3). Compare with FIG. 4). The sealed interface between the mandrel 32 and the post 38 of the base assembly 20 is advantageous and is achieved by imposing an o-ring 94, which o-ring 94 is a post ( Between the clamp end 40 of 38 and the floor 90 of the top 84 of the mandrel 32, it is received around the post 38 near the clamp end 40. This seal helps to prevent fluid or other contaminants from entering the handle 22. This seal also facilitates the last 30 ° of tightening (ie rotation) of the handle by the operator and makes it easier to remove the grip from the handguard. Finally, in order to maintain a debris-free environment, the upper portion 84 of the mandrel 32 preferably includes a hole 96 to facilitate the removal of debris that may collect within the upper portion 84.

Each first wall 88 of the upper portion 84 of the mandrel 32 preferably includes a contoured (eg, inclined) top end 98, which end 98 is in contact with the mandrel 32. It defines the point of contact (ie contact line or surface) for and / or between each clamp 4. As can be readily understood based on what is disclosed at this point, the clamp 24 of the base assembly 20 pivots to the axial positioning of the mandrel 32 relative to the post 38 of the base assembly 20. Answer pvotingly.

In FIG. 7, the alignment and retention mechanism 34 of the present invention allows the mandrel 32 to be properly positioned on the post 38 while limiting its vertical or axial movement relative to the top of the mandrel 32. (84) The first wall 88 is always positioned below and ultimately positioned to engage the clamp 24 of the base assembly 20. The alignment and retention mechanism 34 is compressed with the detent assembly 100, ie the detent pin 102, which is held by the post 38, more preferably by the clamp end 40 of the post 38. A spring 104.

Detent pin 102 preferably has a radiused free end 106 which maintains an extended position by the force of compression spring 104. The detent pin 102 remains held by the wide rounded base 108 on which the spring 104 acts, which extends the radiused free end 106 of the detent pin 102 through the hole. Or from being protruding. Compression spring 104 is held in clamp end 40 of post 38 by threaded set screw 112. Preferably, as is well known, it is further secured using thread locking elements.

The radius free end 106 of the detent pin 102 of the alignment and retention mechanism 34 may have a side 114 of one of the opposing upright wall portions 54 of the clamp end 40 of the post 38. And extends deflected from the hole 110. The upper portion 84 of the mandrel is adapted to lock the detent pin 102 while locking. In this enhancement, one of the second walls 92 of the upper mandrel 32 84 includes a hole or slot 116 for receiving the detent pin 102. Movement of the mandrel 32 relative to the base assembly 20 is limited to the coupling structure or arrangement of the slots 116. The upper end of the second wall 92 is bounded by a ramped surface 119. When fitting the mandrel 32 on the post 38, the detent pin 102 is momentarily pressed into a capture in the slot 116 for later deflected extension. An integral tool 120 is provided as part of the base assembly 20, preferably but not necessarily, to actuate the detent pin. In removing the mandrel 32 from the base assembly 20, the detent pin tool 12 is adapted to be removably received in the axial hole 122 of the post 38 as shown.

The bottom 86 of the mandrel 32 includes a wall 12 extending downward from the top 84 of the mandrel 32 and essentially receives the top 126 of the handle 22. The wall 124 of the mandrel 32 bottom 86 is formed circumferentially to cooperate (ie surround) the top or top 126 of the handle 22, and the top of the mandrel 32. Suspended in the portion 84 and engaged with the wall 124 of the lower 86, the “underside” of the floor 90 of the upper portion 84 of the mandrel 32 is the handle 126. Defines the space in which the top of the door is accommodated.

Connected with the mandrel 32 to detachably secure the inorganic grip assembly of the present invention to the weapon system is a latching assembly 36. The latching assembly or system 36 is preferably but not necessarily (see FIGS. 13 and 14) a detent pin 128 with a chisel tip 130, a compression that deflects the pin 128. A spring 132, and an actuator (eg, stud 134) extending from the detent pin 128. The vertical hole 136 of the mandrel 32 receives a spring 132 and a detent pin 128 for deflecting the pin 128, more preferably the chisel tip 130, and optionally (ie, indexing) Towards the top of the handle 126 adapted to receive indexingly. The bottom 86 wall 124 of the mandrel 32 includes a hole or slot 138 extending through the portion of the mover (ie, the shaft 140 of the stud 134 is detent pin 128). Through the threaded coupling holes 138 in the threaded holes of the < RTI ID = 0.0 > Holes 138 (eg, vertically oriented oval or similar) allow mover 134 to move vertically and therefore detent pin 128. As will be described in detail later, the mover 134 is intended to facilitate thumb control in releasing the chisel tip 130 of the detent pin 128 from the top 126 of the handle 22. Is located.

In the inorganic grip assembly of the present invention, the handle or hand grip 22 is formed to be "fit" throughout the comfort of a typical user's hand, even when using gloves. It is essential that the handle be easily grasped under a variety of environmental conditions. The handle is preferably made of copolymer acetal resin, and more preferably Delrin® Macro E. I. due to its excellent physical and manufacturing properties. Copolymer acetal resin sold by Du Pont De Nemours.

As can be readily understood with reference to FIGS. 4 and 5 or 6, the handle 22 generally has a cross section, which preferably but not necessarily is a circular cross section whose length is not constant throughout. to be. The outer surface 144 extends between opposing ends of the handle, that is, the free ends (ie, the top 146 and the bottom 148 are longitudinally around the handle's longitudinal axis around it). The handle 22 includes separate upper and lower compartments 150 and 152, corresponding substantially to the upper and lower handle portions 126 and 154. Upper compartment 156 (eg , A hole) is accessible at the top end 146 of the handle 22, while the lower compartment 152 is preferably adapted to receive a cap (more preferably and advantageously, a removable locking cap 156). It is accessible at the lower end of the handle.

The lower portion 154 of the handle 22 is preferably uniform throughout its length and has a groove in the outer surface 144, more preferably a spaced circumferential groove, as in the example shown in FIG. 5. Include. It should be noted that other surface adaptations within the lower handle portion 154, as is well known, should be readily understood and understood within the context of the present invention in order to facilitate a secure and comfortable hand grip.

The upper portion 126 of the handle 22 advantageously has non-uniform dimensions throughout its length. More preferably, with respect to the longitudinal axis of the handle 22 and the lower handle portion 154, the radius of the handle 22 first decreases rapidly and then increases rapidly, and the rounded top of the handle 22 edge) 160 (FIG. 5). In addition to ergonomic considerations, this arrangement, more preferably, the portion of the handle 22 that is received within the lower portion 86 of the mandrel 32, provides a mechanical advantage in attaching the assembly to the weapon.

As mentioned above, the top of the handle 126 is adapted to preferably receive the subassembly of the weapon grip assembly. That is, the mandrel 32 coupled with the base assembly 20. The upper compartment 150 (eg, axial or longitudinal hole) receives a post 38 of the base assembly 20 therein. More preferably, the thread of the post 38 is received to engage the threaded portion 162 of the hole 150. More preferred is the Helicoli® threaded metal insert 164 provided for long term secure insertion between the base assembly 20 and the handle 22. The hole 150 is of sufficient length to accommodate the travel length of the post 38 within the handle 22 (ie, the post 38 does not touch the bottom of the clamp 24 to engage the periphery of the weapon but into the handle). Can enter).

The top end 160 of the handle 22 includes a spaced notch 166 that receives the chisel tip 130 of the detent pin 128 of the latching mechanism 36. Rotation of the handle 22 around the post 38 (ie within the hole 150 of the upper handle portion 126) affects the latching mechanism 36: ie, the top edge of the handle 22. When the top perimeter edge 160 contacts the detent pin 128 with the "forward" rotation of the handle (ie, tightening), the inclined surface 168 of the chisel tip 130 is depressed. Allow tent pin 128 to easily move from one notch to another notch 166 spaced apart (ie, ride over the space delimiting the notch); Manipulation of the actuator 134 of the latching mechanism 34 is required to overcome the biased force provided to the detent pin 128, and the "reverse" of the handle 22 to the subassembly. Rotation is allowed (FIGS. 7 and 8).

The lower portion 154 of the handle 22 has a cover or cap 156 that can be reversible received at the free end 148 of the handle 22 (FIG. 4), more preferably, handle 22. It is adapted to receive a mouth 17 of the lower compartment 152. Cap 156 generally includes a head 172 and stem 174 extending from its surface, which stem 174 has threads or other means for engagement with handle 22 (FIG. 4, 5/6). An o-ring 176 is advantageously received over the threaded stem 174 of the cap 156, such that the head of the cap 156 with respect to the mouse 170 of the lower compartment 152 of the handle 22. 172) enclosed.

The head 172 of the cap 156 is preferably formed to fit the shape of the free end 148 of the handle 22 as a whole (FIG. 5 or 6), so that a seamless or pseudo-seam for the base of the handle 22 is provided. seamless) (ie, the interface between the free end 148 of the handle 22 and the cap 156 does not form a sudden outer contour, and the head 172 of the cap 156 does not have any protrusions). Does not include). In promoting this, the head 172 of the cap 156 is generally cylindrical and has a diameter substantially equivalent to the free end 148 of the handle 22.

Although not shown, the head 172 of the cap includes slots, grooves, dimples or other characteristic surfaces (ie, indentation). For example, the outer surface of the cap head 172 may include a crossing slot that the operator can use to open the cap with a 40 mm cartridge, knife, or coin (if needed), and the operator attaches / It further or alternatively includes a fluted edge portin to assist in gripping the cap for removal.

The head 172 of the cap 156 preferably, but not necessarily, includes a latching system 178 that is functionally identical to the latching system of reference numeral 36 described above, in which the cap 156 is removed from the handle 22. Prevent loosening (FIGS. 4 and 5). Keeping the cap in place prevents the unexpected loss caused by the user operating the handle of the weapon grip assembly.

As best shown in FIG. 4, the cap latching system 178 is preferably around a fin 182 that is received and held within a transverse hole 184 of the head 172 of the cap 156. And a pawl 180 that rotates or pivots. This pore 180 is deflected by a compression spring 186 located below its distal portion. In other words, the free end 190 is opposite the latch end 192 of the pooh. As will be described later, the spring 186 receives the latch end 192 of the pooh 180 in a "latched" position with respect to the free end 148 of the handle 22.

The cap head 172 is adapted to be fixed, for example grooved, channeled, slotted, etc. to accommodate the poros 180 of the latching mechanism 178 ( That is, in a locked state, no portion extends beyond the outer surface of the cap head 172 (FIG. 1 or FIG. 5/6). As best shown in FIG. 4, the cap head 172 is notched or braked within its perimeter (ie, sidewall) to settle or receive the latch end 192 of the pooh 80. break) 193. The latch end 192 is dimentioned to exceed the “thickness” (ie, the height of the sidewalls) of the cap head 172 so that the portion cooperatively engages with the free end 148 of the handle 22. .

In order to secure the end cap 156 in place, the handle 22 includes a mating slot or notch 194 (ie castellations), providing a secure engagement of the handle 22 with the pore. The latch ends 192 of the pooh 180 can be accommodated therein to prevent movement (ie, rotation) in one direction of the end cap 156, but provide unlimited movement in the other direction. . More preferably, the mouse 170 of the lower compartment 152 of the handle 22 preferably includes spaced notches 194 to index the latch end 192 of the pooh 180 therein. .

When the operator turns the end cap 156, the latch end 192 of the pooh 180 ratchets past or beyond the notch 194 of the free end 148 of the handle 22.

The latch pawl until the operator stops turning the end cap 156 and engages the latched end 192 with an aligned or registered handle notch of a spaced notch or slot 194 (FIG. 5 or 6). Engagement by 180 prevents the cap from turning in a sudden loosening direction. The operator can be sure that the cap assembly will not be released without the specifically intended action.

As mentioned above, the lower compartment 152 of the handle 22 defines a loading space 196 for the inorganic grip assembly of the present invention. The lower portion 154 inside the handle 22 is empty and is specifically shaped to provide additional functionality, preferably but not necessarily. In the lower compartment, not only the shape of the inner wall surface, but also the depth of the loading space 196 can be used to determine whether two AA batteries 198 (FIG. 5, solid line and FIG. 10) or two DL123 batteries 200 (FIG. 5, broken line) It has been made specifically to accommodate. Other items, including but not limited to gum, cigarettes, matches, and the like, also enter the loading space 196 instead of the battery. A spring, more generally a biasing or elastic element 202, is further provided in the loading space 196 to bias the compartment contents to one side against the wall defining it. As should be readily understood, content shafting should be prevented, and rattles or other noises that may affect the user's position, movement or distraction should first be prevented.

In particular, in FIGS. 5 and 6, the weapon grip assembly of the present invention ready to be mounted on a weapon and the weapon grip assembly mounted on a weapon (eg, a grenade launcher, more preferably an M203 40 mm launcher 128) are shown respectively. As shown, the launcher 28 includes a barrel 72 attached to a receiver 73. The barrel handguard 30 actually surrounds the launcher barrel 72, and the receiver 73. Cooperatively join portions of the launcher handguard 30 to a uniquely ribbed " outer surface, i.e., the surface comprising a plurality of ribs or spaced apart by a plurality of plates 70; It has a ridge 68. The grenade launcher barrel 72 also uniquely includes a handguard locator rivet 76 and a pair of cartridge retainer rivets 77 (FIG. 1). ).

As mentioned above, the fixed or standby state of the weapon grip assembly has a clamp or jaw 24 in a biased open state for receiving the launcher barrel 72 (FIG. 5). In this state, the handle 22 is minimally engaged with the base assembly 20, more preferably a subassembly of the mandrel 32 and the base assembly 20. As can be readily understood by the comparison of FIGS. 5 and 6, the mandrel 32 of FIG. 5 overcomes the deflected movement on the clamp, which effectively pivots to close around the barrel 72. In order to do so, it is not yet located (FIG. 6). When the post 38 of the base assembly 20 is pulled into the handle 20, ie when the handle 22 rotates clockwise around it, the mandrel 32 is the post 38, more generally, It "rides" upward along the handle 22 to engage the clamp 24 for shielding against the base assembly 20. As best shown in FIG. 11, the weapon receiving surface 26 of the clamp 24 receives the selection rib 86 of the launcher handguard 30. The free end 44 of the clamp 24 encounters the handguard 30 on the receiver 73 and its engagement (ie is in close proximity) to prevent rotation of the weapon grip assembly around the barrel 72. Longitudinal movement (e.g., pivoting over the launcher barrel length) is inhibited by the upper portion of the base assembly 20 being coupled to the inner shape 93 of the clamp (FIG. 7).

A design feature of the preferred embodiment of the present invention is that once weakened, it is impossible to detach the weapon grip assembly from the weapon's handguard at an angle close to 90 °. This is because the open end of the clamp tightly surrounds the handguard and exceeds its maximum radius. This eliminates the need for excessive internal pressure on the handguard to achieve grip operation (i.e. it does not need to be tightened tightly) and clamps only around the diameter of the handguard to prevent the arms grip assembly from releasing from the handguard. Means that only an interference fit of is needed. The tightening achieved by turning the handguard is only used to keep the grip clamp close to the handguard contour, even when pulled by the operator in normal use. It is not about sinning to grab, but just about keeping it very close. The clamps fail to open because they must be released, and the design and sanction of the clamps make it virtually impossible to open within the range of pressures that can be applied by the person using the weapon system shown in FIG.

Movement forward and backward of the weapon grip assembly (ie along the length of the handguard) is selected for capture by the clamp ends 40 of the mandrels 32 and the posts 38 and the jaws 24. Controlled by associated cooperative fit with handguard ribs 80 near the ribs 82 (ie, three successive handguard ribs are involved in the attachment of the inorganic grip assembly of the present invention. FIG. 7).

The movement of the arms grip assembly around or around the handguard is controlled by the fit of the free end 44 of the clamp 24 up to the vertical lip 64 of the handguard 30 (ie the hand). The boundary between the guard 30 and the receiver 73). The amount of operation is calculated to hold the manufacturing guard of the handguard, the grip of the grip and the debris.

11 and 12, an accessory, i.e., an inorganic grip assembly 16 of the present invention with a flashlight assembly is shown. It is to be understood that various known accessories, flashlights, including but not limited to, are supported or carried by the inorganic grip assembly of the present invention. For this purpose, it is considered that the grooved bracket 206 is attached to the outer surface 85 of the upper portion 84 of the mandrel 32 using a threaded fastener 207, more preferably. One of the pair of first walls 88 facing each other. By this design, the accessory can be mounted on one or both sides of the weapon grip assembly, depending on the operator's choice.

In the above case, the flashlight assembly 204 is tied to an end cap 212 facing the flashlight 208 (ie, the forward end 214 of the flashlight 208) with a remotely controllable power switch. The pad switch 210, the bracket 216 for coupling the flashlight 208 to the accessory bracket 206 attached to the mandrel 32, and the pad switch (at the handle 22 of the inorganic grip assembly 16). A spring clip 218 holding 210. The spring clip 218 includes an elastic member 220 that extends from the base 222 as a whole, which is fitly received in the groove 158 of the lower portion 154 of the handle 22. The outer surface 224 of the base 222 of the spring clip 218 is a pad extending from the flashlight 208 including a hook and part of a loop fastener system, or other removable fastening means. Removably holds the switch 210. As can be easily understood by FIG. 11, the inorganic grip assembly provides a beneficial position of the flashlight, also provides a beneficial position to the switch for the most effective and easy operation of the switch, and by allowing handle rotation of the grip assembly Allows you to remove it from the weapon without releasing the flashlight assembly component (ie, switch).

With reference now to FIGS. 13-16, another embodiment of the inorganic grip of the present invention is shown. More preferably, FIGS. 13 and 14 show a weapon grip assembly for removably securing the hand hold to the front of the weapon, ie the hand guard. 15 and 16, on the other hand, include an alternative clamp or jaw arrangement, the jaws are easily received around the rails of known rail adapter systems (RAS). The weapon grip of the present invention includes (eg is provided) interchangeable clamps or jaws to provide a variety of devices that are considered important to users of weapons or weapon systems. In addition, other embodiments of the present invention are not intended to limit other device styles and features should be considered. It should also be noted that the symbols have been used to designate parts.

In the device of FIG. 13, the alignment and retention mechanism 34 of the mandrel 32, associated with the base assembly 20 of the device of FIG. 4, has been omitted. In keeping with the above omission, the mandrel 32 of the present embodiment need not include an upper portion 84 (FIG. 4) with the second wall 92 of the previous embodiment, but instead the mandrel 32 The upper portion 84 of contains only a set of opposing pairs of walls 88 (ie, the first wall as mentioned above). The mandrel 32 is preferably adapted to fit the profile of the upper end 146 of the handle 22, the clamp end 24 of the post 38, and the outer surface 42 of the clamp 24. Shapes are formed and sized. The mandrel 32 fits into the handle 22 is sized to fit the entire top end 146 of the handle 22 and the operator's hand may be in contact with this area of the assembly. Match the outer diameter with a smooth change. The bottom of the bottom 86 of the mandreal 32 is smooth because the arms grip assembly is adapted to firmly and securely engage the top end 146 of the handle 22 when it fits into the barrel handguard.

In the previous embodiment, the upper contoured edge or surface 78 of the clamp end 40 of the post 38 is engaged with the clamp, providing interference fit to the inorganic grip assembly. That is, it partially encloses the selection handguard ribs 82, " filling " the flat 70 immediately adjacent to the selection ribs 82, and adjoins the ribs 80 adjacent to the selection ribs 82. (FIG. 9). The remaining structure of the device of FIG. 13, including its interrelationship, is readily understood by comparison and reference to FIG. 4.

In the device of FIG. 14, the alignment and retention mechanism 34 (FIG. 4) for the mandrel 32 is omitted entirely too, and entirely includes the upper mandrel portion as depicted for the device of FIG. 13. In contrast to the embodiment described above, the apparatus provides an alternate interface between the handle 22 and the base assembly 20 and another latching assembly 230 for removably securing the weapon grip assembly to the weapon. Include.

The mandrel 32, more preferably, bottom 86, of the inorganic grip assembly of FIG. 14 includes a latching assembly 230 comprising a pore 232, a pivot pin 234, and a biasing spring 236. Integrate. The hand grip or handle 22 incorporates a mating slot 238 for the latch end 240 of the pore 232, at or near the upper end portion 126. Receiving the latch end 240 of the pore 232 by the slot of the mating slot 238, the handle 22 provides a secure engagement of the latching assembly 23, such that the mandrel 32 / base assembly 20 Is coupled with the handle 22. Movement in one direction (ie, direction to release the handle) is prevented or inhibited, while movement in the other direction (ie, direction to tighten the handle) of the handle is not allowed or restricted.

Pore 232 of latching assembly 230 rotates around pin 234, held and held by mandrel 32. For example, this is done by inserting pin 234 into hole 242 in lower portion 86 of mandrel 32. Pore 232 is deflected by a torsion spring 236 wrapped around a portion of pin 234 (ie, either side or opposite side of poe 232). By means of the arrangement shown, the latch end 240 of the pore 232 maintains a "latched" position (ie, the latch end 240 of the pore 232 has a mating slot ( Pivot until received in slot 238).

When the operator turns the handle 22 of the weapon grip assembly while closing the clamp 24 around the launcher handguard 30, or other component of the tightening weapon, the poo 232 stops the handle from rotating. Ratchet past handle slot 238 until The latch end 240 of the poo 232 engages the handle slot that registers at its most tight line up or therein. Engagement by latch pore 232 prevents the handle 22 from turning back in the unwinding direction. The operator can be sure that the system will not be released without special intentional actions.

To remove the hand grip, the operator presses the upper exterior surface of poo 232 (eg, illustrated knurled area 244) against spring pressure while rotating in the direction in which the handle is released. . While pressed, poo 232 will allow unrestricted movement of the handle and upon release, poo 232 is ready to re-lock the handle's rotation against rotation in the direction of release of the handle. Will come.

With respect to the interface of the subassembly comprising coupling the mandrel 32 and the base assembly 20 to the handle 22, the handle 22 preferably has holes 150 in its top surface 146. (Ie, holes). Steel threaded inserts 246 are made to engage threaded posts or studs 38 of base assembly 20 and are securely received within holes 150. A fastening means, for example, a threaded fastener 248 coupled with a washer 250 as shown, couples the handle 22 to the subassembly. More preferably, a threaded fastener 248 is received in an axial hole of the post 38 that is threadedly received in the insert 246. If the handle is excessively tightened while the weapon grip assembly is mounted to the weapon, the insert 246 ensures that the operator will not damage the grip handle 22 with the base assembly threaded stud 38. The depth of the handle hole 150 allows the stud 38 to be inserted into the handle 22 when needed for proper operation of the clamp 24.

  As mentioned above, the posts 38 of the base assembly 20 are threaded into the handle 22 by rotation. This allows full control of the attachment or detachment of the device with only one hand. When turning the handle about one turn, from a clamp that opens wide enough to fit over the handguard rib, the thread pitch on the stud 38 has been specially selected, which allows the operator to turn the clamp on the barrel. Make sure that it is completely closed around the guard. This has the advantage of being convenient and quick to operate. While maintaining the tightening set by the operator without the need for a locking mechanism, the added pitch also allows the handle to be clamped by the strongest operator without fear of thread wear.

The base threaded stud 38 preferably has a keyway (not shown) along its length. This keyhole allows the fitting to be fitted or mounted to a device on a bracket received on the post 38 to maintain an independent proper alignment of handle position or movement (i.e., while the handle rotates, Make sure the flashlight or aiming laser bracket is always pointed "forward"). Such brackets can be used to position the accessory on either side of the handle (ie, left or right) surface, and one or more brackets can be stacked so that auxiliary or accessory equipment can be used simultaneously on both right and left sides. Stacked.

15 and 16, a clamp 324 is shown that grasps a portion of another embodiment of the present inorganic grip, ie the rail 325 of the RAS. In preliminary terms, a clamp or jaw supporting the structure of FIG. 15 is generally presented, previously described with respect to FIG. 5, a jaw supporting the structure of FIG. 16 is generally presented, and in FIG. 4. Has been described previously. While the inorganic grip of FIGS. 15/16 is preferably standing alone, a dedicated device, a rail containing a jaw 324 may optionally be provided as part of or together with the embodiment presented above ( In other words, packaged or bundled, it is easy and detachable to switch from a grenade launcher grip arrangement to a RAS grip arrangement, where it may be advantageous or necessary.

This embodiment of the inorganic grip is characterized by opposing pairs of jaws 324 (ie, clamping jaws), each jaw having a profiled lateral surface (FIGS. 15 and 16). The jaw 324 is arranged on the clamp base 329 (ie, the clamp end 40 of the post 38 of the clamp base 329) so that the profiled surface 327 is on the opposite side: the clamp 324 is When pulled together, a rail is formed in the interior of which the rail of the front of the weapon is captured, which receives a surface or volume (FIG. 15). With movable jaws 324 adapted to accommodate the lateral edges 331 of the rails of the RAS, the rails are held in a consistent manner to achieve the fastest and most reliable placement of the grip anywhere along the rail length. It does not remove from the rails of the already present accessories in order to slidely position the grips known to date.

As the launcher for receiving the jaw (FIG. 4), the RAS jaw 324 traverses the opposing upright wall segment 54 of the clamp end 40 of the post 38 of the clamp base 329. The clamp 324 is fixed to the post 38 via a set of through-holes 53 which are connected to the clamp base 329 by the pins 52 and paired and aligned. The clamp pin defines the pivot axis of each clamp.

One for each clamp 324, a compression spring 56 is between the outer surface of its base and the surface 58 extending from the opposing upright wall portion 54 of the clamp end 40 of the post 38. It is placed to be inserted into (i.e., the floor of the clamp receiving the "space", see Figures 4 and 5/6). With the weapon grip assembly secured, the spring 56 biases each clamp 324 (ie, exerts a force on the base end 46 of the clamp 324) so that the clamp 324 lifts the portion of the weapon. It is “opened” in preparation for grabbing. The biasing effect of the spring 56 on the clamp 324 is such that the mandrel 32, more preferably, to the point where the spring 56 is compressed and the free end 44 of the clamp 24 is secured around the rail The mandrel is involved in the jaw operation, thereby making it invalid or more globally controlled. More preferably, the range of pivot movement of the jaws is adjusted or limited at least indirectly by the mandrel: it is inserted between the top of the handle and the jaw and received around the post of the clamp base. As mentioned above, the mandrel "raises" the post of the clamp base when the mandrel is pulled into the axial hole of the handle while the handle associated with the clamp base is rotating.

As described above with respect to FIG. 7, the alignment and retention mechanism 34 of the present invention is appropriately positioned to allow the mandrel 32 to act on the post 38 while limiting the range of vertical or axial movement. 15, the first wall 88 of the top 84 of the mandrel 32 is always positioned to underlay and ultimately engage the clamp 24 of the base assembly 20.

There are other variations of the invention, some of which will be apparent to those skilled in the art. In many respects, it should be understood that the above disclosure of the present invention is merely illustrative. In the specific matters without departing from the scope of the present invention, modifications may be made in particular to the shape, size, material and arrangement of parts. Accordingly, the scope of the invention is defined in the language of the appended claims.
