  • an autoloading handgun mechanism constructed in accordance with the present invention is illustrated generally at 10 and incorporates an elongate, gripless frame structure shown generally at 12 and an integral handgrip interconnected with the frame and shown generally at 14.
  • the frame structure is preferably composed of a metal material and the handgrip structure is preferably composed of a polymer material but other materials may be employed for the frame and handgrip structures without departing from the spirit and scope of this invention.
  • metal or polymer may be specifically mentioned, it is not intended to limit this invention to these specific materials.
  • the frame structure 12 is composed of a metal or any other material having the substantial structural integrity of metal or otherwise being suitable for the intended purpose. From the standpoint of metal, a wide range of metals and metal composites may be employed to form the frame structure.

  • the frame structure defines a forwardly extending U-shaped guide trough portion defining a dust cover for the recoil assembly and having flat surface portions 16 and 18 on each side thereof which may be disposed in substantially coplanar relation.
  • the side surface portions are of sufficient structural integrity for support of various sighting devices such as optical sights.
  • the frame of the present invention has a dust cover thickness dimension of .830 inches to provide wall structure of greater thickness and structural integrity for drilled and tapped support of optical sighting devices.
  • This particular thickness dimension is not intended to limit the invention, it being within the scope of this invention to employ any desirable thickness dimension for the dust cover.
  • Opposed planar side surfaces 20 and 22 define the opposite side of the frame structure of Fig. 1 and are shown in Figs. 3 and 4 respectively.
  • the frame structure further defines opposed guide rails 24 and 26 which are defined by respective elongate parallel guide grooves 28 and 30. The guide rails and grooves receive the respective guide flanges of an elongate conventional slide member, not shown.
  • the slide member may be the conventional slide of a 1911 A1 handgun or a corresponding slide having appropriate guide flanges. It should be born in mind that the present invention is not intended to be limited strictly to the use of a conventional 1911 A1 slide; the guide rails and slide may be of differing dimension as compared to that of the model 1911 A1 handgun in the event such is desired. This character of handgun construction is preferred only because it lends use of the frame/grip assembly of the present invention to utilization of standard 1911 A1 handgun components in operative assembly with the frame/grip assembly of this invention.
  • the frame further defines an elongate recess 32 within in which is received a conventional slide stop having a portion thereof received within a slide stop receptacle 34. Apertures 36 on opposed sides of the frame 12 are provided to receive the transverse pivot pin 35 of the slide stop 37.
  • the rear portion of the frame structure 12 is of bifurcated configuration by virtue of a central slot 38 and defines opposed, spaced, rearwardly extending projections 40 and 42 having aligned apertures 44 for receiving a conventional hammer mounting pin.
  • Side surface 16 of the frame defines a specifically configured aperture 46 for receiving a conventional thumb safety lock.
  • the forward U-shaped guide trough or dust cover portion 18 defines elongate narrow top surfaces 48 and 50 which are seen in Figs. 2 and 5, and which are disposed in spaced, parallel, coplanar relation. Top surfaces 48 and 50 are positioned a few thousandths of an inch lower as compared to the bottom surface 52 of the respective guide grooves 28 and 30 for the purpose of providing clearance for the retainer flanges of a conventional slide.
  • the U-shaped portion 18 of the frame forms a substantially cylindrical trough portion 54 which receives the recoil spring and spring guide assembly of the conventional 1911 A1 handgun.
  • the forward portion of the frame also defines a bottom recess 56 to provide clearance for the barrel link.
  • the frame 12 defines opposed grip seat bosses 58 and 60 which have a generally rectangular upper portion.
  • the grip seat bosses 58 and 60 each define grip receiving seat depressions or recesses such as shown at 62 which are of a configuration conforming to the upper configuration of the grip structure 14.
  • the handgrip seat recesses 62 are defined in part by a peripheral structural support shoulder 64 which almost entirely encompasses the upper peripheral edges 66-68 of the handgrip structure 14 as shown in Fig. 1 and which provides support in shear for the mating edges of the handgrip.
  • the handgrip seat bosses 58 and 60 further define one or more keyways such as shown at 68 which define alignment edges 70.
  • the keyways are located within the respective handgrip recesses 62 and receive interlocking keys 72 of corresponding configuration and location as shown in Figs. 7 and 13 so as to be received in mechanically interlocking relation with respect to the keyway slots 68.
  • the alignment edges 70 of the keyways are preferably oriented to establish a desired handgrip angle, for example 17.5° relative to the guide rails.
  • the keys and keyways may be oriented to establish any suitable directional relationship for keyed assembly of the handgrip and frame constructions.
  • the handgrip may define keyways within which are received keys that are defined by the frame.

  • the frame structure further defines a connecting projection 84 forming a connecting pin aperture 86.
  • a forwardly projecting platform portion 78 of the handgrip structure 14 defines a substantially planar support surface 88 which is disposed in face-to-face, seated relation with respect to surface 78 of the frame structure when the handgrip is in proper assembly with the frame. In this position the peripheral edge 80 provides support in shear for the periphery of the planar engagement plate 86.
  • the forward portion of the trigger guard support platform structure 78 further defines a depression forming a connecting receptacle 90 within which the connecting projection 84 is received in close fitting relation.
  • the connecting projection 84 is properly positioned within the receptacle 90, the aperture 86 is positioned in registry with aperture 92 of the trigger guard 76 such that a transverse locking device such as a pin, screw, etc. may be secured to the frame/handgrip assembly to lock the projection 84 in intimate, secured relation within the recess 90.
  • This structural relationship provides lateral stability for the forward frame/handgrip connection as well as supporting the frame against upward or downward rotation relative to the handgrip.
  • bushings 96 which are located internally of the frame structure 12.
  • the bushings 96 have flats 98 formed thereon which engage a horizontal shoulder anti-rotation 100 formed by an internal step of the metal frame.
  • the bushings 96 are preferably press-fitted into internal apertures of the frame. The bushings 96, in addition to functioning as elements of the handgrip retainer structure, secure the handgrip and frame in immovable assembly.
  • the bushings 96 retain the keys of the handgrip in fully seated relation within the keyways of the frame and thus secure the frame and handgrip in immovable, force transmitting relation, thus enabling the frame and handgrip to resist any tendency for separation during shooting activities.
  • the bushings 96 further provide for lateral location of the upper portion of the staggered row magazine which is received within the magazine receptacle of the handgun. This feature will be described in greater detail in relation with the staggered row magazine to be discussed hereinbelow.
  • the handgrip retention bushings may be press fitted into appropriate receptacles defined within the frame structure and may be secured against rotation by any number of suitable means.
  • the bushings may be pinned to the frame structure or may be of non- circular configuration to be received within a corresponding non-circular receptacle. If desired, the bushings may be externally threaded for positive retention within internally threaded bushing receptacles formed in the frame structure.
  • the handgrip seat boss 58 defines an internal passage 102 having a small forward bored section 104 and a larger rear bored section 106 to define an elongate internal receptacle for receiving a conventional spring-urged slide stop and thumb safety detent assembly.
  • the handgrip seat boss 60 forms a curved, undercut slot 108 which is provided to receive the projecting guide tab portion of a conventional ambidextrous safety having its pivot shaft received by aligned frame openings 110.
  • a conventional thumb safety is also supported by the same shaft.
  • the undercut slot 108 serves to capture the ambidextrous safety and retain it in movable assembly with the frame structure.
  • the frame/handgrip assembly of the present invention though adapted to receive standard cartridge magazines with serially oriented cartridges may, if desired, define a rather wide magazine receptacle for receiving large staggered row cartridge magazines therein.
  • a magazine receptacle is defined cooperatively by the frame and handgrip structures.
  • the frame 12 forms a top opening 114 of generally rectangular configuration having its upper, forward portion in registry with a curved cartridge feed depression or recess 116 which serves to guide cartridges into the cartridge chamber of the handgun barrel.
  • the generally rectangular opening 14 defines the upper portion of a cartridge magazine receptacle 118.
  • the cartridge magazine receptacle as shown in the bottom view of Fig. 6, is defined by internal stepped surfaces 120 and 122.
  • the internal surfaces of the magazine receptacle are also defined in part by the inner surfaces of a trigger bow which is movably received within a trigger track which is cooperatively defined by track section 124 of the frame as shown in Fig. 15 and track section 126 of the handgrip as shown in Fig. 13.
  • the trigger shoe and trigger bow are wholly contained within the frame/handgrip assembly with upward movement thereof being restrained by the trigger bow guide surface 125 of the frame.
  • a groove is shown at 126 which cooperatively defines a portion of the trigger bow track of the handgun assembly.
  • the groove or recess defining trigger track section 126 is in communication with a trigger shoe opening 128 through which the finger engaging trigger shoe portion of the trigger projects for manipulative engagement during firing of the handgun.
  • the trigger bow portion of the trigger will be captured and supported against all but linear movement by the interdependent relationship of the frame and handgrip and with its rearward linear movement being limited by the curved rear portion of the trigger track section 124 of the frame. Consequently, in the preferred embodiment of Fig. 6 the trigger must be in place when the frame and handgrip are assembled.
  • the rear portion of the handgrip or frame may be machined to define an opening through which the trigger assembly passes during assembly and disassembly.
  • the internal surface configuration of the opposed internal connection portions 75 and 77 of the handgrip structure 14 defines a pair of keys 72 and 74 to be received in interlocking relation within the keyways 68 and 70 of the frame.
  • the keys 72 and 74 may be formed integrally with the handgrip structure such as by molding, they are preferably composed of metal or any other suitable structural material defined by an insert 130 which is molded into or otherwise attached to the handgrip structure as shown in Fig. 18.
  • the insert 130 is composed of a hardened metal and defines a plurality of openings 132 through which moldable material of the handgrip extends in order to establish a positive, interlocked relationship with the material of the handgrip structure.
  • the insert 130 defines an upper opening 136 to receive the locking screw or rivit that is extended through bushing opening 94 and provides for exceptional strength of the structural interconnection between the frame and the handgrip structures.
  • the inserts 72 and 74 each form anti-rotation shoulders 137 against which are positioned frame anti-rotation shoulders 139 when the frame and handgrip are properly assembled.
  • These anti-rotation shoulders of the frame and handgrip provide for force transmission in a direction that is transverse to the orientation of the parallel edges 139 and 141 of the keys and substantially parallel to the guide rails 24 and 26.
  • the anti-rotation shoulders 137 are located a substantial distance from the point of rotation established by the connecting screws extending through openings 94 and 136 and thus the resulting lever arm about the pivot point provides for significant force resisting capability. Relative adjustment of the frame and handgrip is easily facilitated by the interengaging positioning shoulders 137 and 139. Shoulder 139 may be adjusted by adding or removing metal therefrom. This feature makes the fit of the frame and handgrip "gunsmithable" for alteration of the relative positioning or orientation of frame and handgrip.
  • the handgrip 14 defines a cartridge magazine receptacle passage 138 which is internally belled at its lower extremity 140 so as to provide for efficient guiding the upper end of a cartridge magazine therein. This is especially an advantage to facilitate rapid magazine reloading.
  • the lower end of the handgrip 14, about the cartridge magazine opening, defines a stop shoulder 142 which encompasses the magazine opening and which is engaged by a positioning surface 144 formed as the upwardly directed surface of a magazine base pad 146 of a staggered row cartridge row magazine 148 which is discussed hereinbelow in relation with Figs. 18-22.
  • the handgrip construction 14 comprises a structural element of the frame/handgrip assembly; thus it needs no internal metal handgrip structure as is typically the case with most autoloading handguns.
  • the handgrip structure 14 defines diamond shaped checkering 150 which is integral with the material from which the handgrip is composed. This checkering is intended to provide the handgrip with an outer, roughened or textured surface to enable the handgun assembly to be securely gripped by the user even under warm conditions when the user's hands may be perspiring.
  • This checkered surface preparation is also designed to enhance the structural integrity of the handgrip.
  • the forward curved surface area 152 of the handgun structure is provided with rather fine checkering which further assists the user's manual gripping of the handgun assembly.
  • the textured surfaces 150-152 will effectively permit the user to efficiently grip the handgun assembly so as to effectively resist any slipping of the handgun relative to the hands of the user during recoil as the handgun is fired.
  • the forward blunt surface 154 of the integral trigger guard portion of the handgrip 54 is provided with fine texturing for efficient gripping thereof and is oriented in substantially normal relation with respect to the planar surface 88. This feature enables efficient two-handed gripping of the handgun assembly to effectively enable stabilization of the handgun during two-handed, rapid fire conditions.
  • the trigger guard portion of the handgrip construction may define any suitable connection structure, i.e., a dove-tail groove as shown at 155 for support of sighting devices such as laser or infrared sighting devices, global positioning devices, telemetry devices, etc. These features are especially applicable to military or police usage but may have application for civilian usage as well.
  • the handgrip may also define a forwardly extending U- Shaped trough or "dust cover" as shown at 157 in Fig. 14 for establishment of an interfitting relation with a frame structure which does not incorporate a dust cover.
  • the handgrip structure 14 is preferably composed of a readily moldable material such as any one of a number of suitable polymer materials or any one of a number of suitable metals. From the standpoint of metals, the handgrip may be composed of steel, aluminum, aluminum alloy, titanium, etc. The handgrip is preferably a molded structure for ease of manufacturing although, if desired, it may be machined or manufactured by any other suitable process as well. Especially when composed of polymer material, the handgrip structure of the handgun assembly may be substantially rigid from the standpoint of gripping but may have a controlled flexibility, allowing a certain degree of flexure during firing.
  • the keyed connection between the frame and handgrip may be designed to provide a degree of cushioning to promote a "soft feel" during shooting.
  • the magazine receptacle portion of the handgrip structure is formed in part by an integral wall structure 156 defining a centrally oriented, vertically opening slot 158.
  • Opposed, generally parallel surfaces 160 and 162 are integral with the handgrip structure and project rearwardly of the wall structure 156.
  • the lower portion of the wall structure defines a transverse structural rib 164 located immediately below a transverse spring locator slot 166.
  • the reinforcement rib 164 is provided in the handgrip structure for receiving and locating a conventional leaf spring of the autoloading handgun assembly.
  • the opposed parallel surfaces 160 and 162, together with the wall or partition 156 cooperatively form an elongate, vertically oriented receptacle or slot which receives a mainspring housing 163.
  • the mainspring housing 163 is pinned by a suitable connector extending through aperture 165 and defines an internal mainspring receptacle 167.
  • the mainspring though wholly contained within the handgrip is structurally and operationally interdependent upon the hammer assembly which is wholly contained within the frame. This interdependent characteristic is not present in handguns wherein the handgrip section is defined by the frame.
  • the lower, generally tubular portion of the handgrip structure 14 defines a forwardly projecting arcuate boss 168 having an arcuate, tapered surface 170 which merges with the textured forward surface 152.
  • the boss 168 together with its tapered surface, defines an inclined forward projection which, when the handgun assembly is held, forms a tapered, arcuate ledge position for engagement by the lower portion of the little finger of the user.
  • This arcuate, tapered ledge further functions to establish a firm structural interrelation between the hand of the user and the handgrip portion of the frame/handgrip assembly.
  • the arcuate boss 168 also functions to enhance the structural integrity of the lower portion of the tubular handgrip structure.
  • the enhanced volume staggered row cartridge magazine 148 defines opposed side surfaces 172 and 174 which are of generally planar configuration and which are disposed in substantially parallel relation. Surfaces 172 and 174 merge smoothly with converging tapered surface portions 176 and 178 respectively.
  • the tapered upper side surface portions 176 and 178 of the magazine have intermediate, opposed, inclined depressions 180 and 182 which, in conventional manner, form inwardly inclined guide ridges to guide cartridges during upward movement thereof from their staggered row positions so that they emerge at the upper, discharge opening 184 in serially oriented fashion and in location to be transported forwardly into the cartridge chamber of the handgun barrel.
  • the upper rear portion of the cartridge magazine defines a pair of opposed inwardly directed retainer flanges 186 and 188 which define a spacing therebetween of less dimension than the width of the cartridges to be contained in the magazine.
  • the flanges 186 and 188 secure the rear portion of the cartridges against upward movement and release the cartridges only after sufficient forward movement thereof the clear the retainer flanges.
  • a follower member 190 of greater lateral width than the spacing of the retainer flanges 186 and 188 is urged upwardly against the retainer flanges or against cartridges contained in the magazine by means of a coil spring 187.
  • the follower 190 defines an elongate, arcuate cartridge trough 192 which functions to orient the cartridges with respect to the magazine and to serve as a guiding surface for the last of the serially oriented cartridges.
  • the cartridge magazine also defines a substantially planar end surface 194 as shown in Fig. 19 and a more rounded end surface 196 as shown in Fig. 20. These end surfaces are preferably integral with the side surfaces 176 and 178. For cartridge inspection the side surfaces define a plurality of apertures 198 through which cartridges may be inspected to determine by rough estimate the number of cartridges remaining within the magazine at any given time.
  • the base pad 146 is preferably of molded construction, being molded from any one of a number of polymer materials.
  • the base pad structure forms an internal receptacle 200 within which the lower end of the cartridge magazine is received.
  • the lower portions of the side surfaces 172 and 174 are slightly belled outwardly and are received in interlocking relation with internal, lateral slots 202 and 204 to thus retain the base pad in firmly assembled relation with the elongate tubular portion of the magazine.
  • the base pad structure is designed to effect release of the gas prior to the development of any significant gas pressure that could otherwise rupture the magazine and/or the handgrip portion of the handgun.
  • This safety feature is provided by forming a blowout opening in the lower wall 206 of the base pad and locating a blowout plate 208 within the base pad which is held in place by the spring 187 and which defines a weakened wall structure which will be sheared and displaced through the base pad opening in the event excessive pressure is encountered.
  • the rupture disc 208 may define an aesthetically pleasing pattern such as the star pattern shown at 210.
  • this invention accomplishes the provision of a frame/handgrip assembly for autoloading handguns which establishes a unique mechanically interlocked assembly of a gripless frame structure and a handgrip structure.
  • the frame/handgrip assembly provides wholly contained structural elements of the handgrip which are functionally interdependent with structural and operational components located wholly within the frame and vice versa.
  • the frame/handgrip assembly provides the user with the capability of selecting an autoloading handgun having standard cartridge capacity or a handgun having an enhanced cartridge capacity while minimizing the external thickness of the handgrip portion of the handgun and while minimizing the overall weight of the handgun assembly.
  • a autoloading handgun capability in a handgun having a handgrip dimension and overall weight that can be significantly less than that of a standard Government Model 1911-A1 handgun or closely approximate the dimension and weight of a conventional Model 1911 A1 handgun when the handgun has enhanced cartridge capacity.
  • a slide mechanism 13 is disposed in movable assembly with the elongate gripless frame and incorporates a barrel 212 having a barrel bushing 214 located about its forward end and with the barrel link 11 of the bushing located in abutting relation with the forward end of the slide.
  • the slide is urged to the position shown in Fig. 24 by a recoil spring 216 which permits the slide to move rearwardly under the force of a discharged cartridge and functions to cushion the recoil.
  • the slide mechanism incorporates a firing pin 218 which is urged rearwardly by a firing pin spring 220 and permits forward striking movement of the firing pin when it is struck by the hammer 222.

Abstract

Une arme de poing à chargement automatique telle que le pistolet modèle US 1911-A1 comporte un agencement intégré cadre/crosse sous la forme d'un cadre allongé sans crosse, de préférence métallique, ayant des rails de guidage pour recevoir un mécanisme coulissant. Le cadre sans crosse comporte des sièges opposés pour la crosse, auxquels la crosse formée en une seule pièce est verrouillée par liaison de forme. La crosse comporte un pontet solidaire. Le pontet et les éléments d'accouplement de la crosse sont physiquement verrouillés au cadre par des vis, des goupilles, un adhésif, par surmoulage, etc. Le cadre et la crosse combinés peuvent délimiter ensemble un logement de grandes dimensions pour un chargeur de grande taille contenant des cartouches placées en quinconce. La crosse est un élément structural de l'agencement cadre/crosse et elle comporte des surfaces externes agencées pour permettre une bonne préhension, tout en ayant une épaisseur maximum qui est sensiblement identique à celle de la crosse du pistolet standard modèle US 1911-A1. Le cadre (12) et la crosse (14) coopèrent pour loger en les enfermant, des composants structuraux et fonctionnels, tout en assurant leur coopération fonctionnelle.
