DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
(31) In describing the preferred embodiment of the present invention, reference will be made herein to
(32) In one embodiment, the present invention introduces an extendable slide member on at least one side of a pistol slide action, and preferably on both sides of a pistol slide action that provides leverage and a gripping base for a user to pull back or rack the slide along guides on a pistol frame, in a longitudinal motion relative to the pistol frame.
(33)
(34) Pistol 10 represents a common pistol construction with general components including a barrel 18, a forward sight 20, a muzzle 22, a slide 12 with an ejection aperture 24, a rear sight 26, a grip 28, trigger 30, and trigger guard 32, to name a few. In this first embodiment, the present invention introduces at least one slide member 34, and in this illustrative example, two slide members 34, that essentially extend a gripping or grasping portion of slide 12 in the lateral direction to facilitate gripping or holding the slide when a user attempts to rack the slide. In this embodiment, two slide members 34 are used, one on each side of slide 12, for delivering a balanced retraction force during racking. Slide members 34 may be integral with slide 12. Slide members 34 may be in a fixed position, extending laterally outwards from slide 12; however, more preferably, slide members 34 are movably attached to slide 12 so that each is an extendable and retractable member. In this manner, slide member 34 provides an extended grip portion or finger-hold for assisting the user in racking the slide without slipping or instigating slide bite, and can be fully retracted so as not to affect the slim-lined nature of the pistol.
(35) Slide 12 with slide members 34 may still include serrations 42 for enhancing the user's hand grip on the slide. These serrations 42 may further be formed on slide members 34 as well in the event the user elects to rack slide 12 by conventional gripping, without extending slide members 34 laterally outwards.
(36) In
(37)
(38)
(39)
(40) When slide member 34 is in the retracted position, lever arm 46 is secured within slot 52 of slide 12. Slot 52 is defined on slide 12 by sidewall 54, located at the breech end of slot 52, and sidewall 56, located at the muzzle end of slot 52. A top segment 58 on slide 34 defines a top portion of slot 52. At one end, top segment 58 extends to, and partially forms, groove 38 with sidewall 54, to assist in securing connection segment 36. At the forward or breech end of slot 52, top portion 58 extends to groove 60 to form a gap with sidewall 56 for securing a handle portion 50 of slide member 34 opposite connection segment 36.
(41) Handle portion 50 of slide member 34 is at an end of slide member 34, opposite connection segment 36, and is an upward extending portion adjacent to, and integral with, lever arm 46. Handle portion 50 is designed to extend at least to the top surface of slide 12 and top segment 58 in order to provide a vertical extension 51 for grasping slide member 34 to extend slide member 34 laterally outwards. Handle portion 50 may further form a snug or snap fit with groove 60, allowing slide member 34 to be held securing in place when in the retracted position.
(42) The bottom surface of slot 52 preferably includes an indentation 64 positioned to receive the center of connection segment 36 when connection segment 36 is placed within groove 38 of slot 52. Indentation 64 is adapted to receive a detent or pin 66 located on the bottom of connection segment 36 of slide member 34 to secure the bottom of connection segment 36 in the bottom of slot 52. Conversely, a detent may be located on the bottom surface of slot 52 and received by an indentation in the bottom of connection segment 36. The combination of the detent/indentation forms a pivot point that secures the bottom of connection segment 36 while allowing for rotation. Curved groove 38 at the upper portion of slot 52 wraps partially around connection segment 36 at the top portion of connection segment 36 and serves to hold rotatable slide member 12.
(43)
(44) This attachment mechanism applies a bias force against connection segment 36 to hold slide member 34 in position. Grasping handle portion 50 and extending lever arm 46 laterally outwards will slightly compress bearing 74 against spring 72, allowing connection segment 36 to rotate more easily. Connection segment 36 may include an indentation to receive bearing 74 and secure connection segment 36 in place.
(45) Alternatively, connection segment 36 may include at least one flattened side 68 to assist in forming a locking or secured indication when slide member 34 is fully retracted within slot 52 (Refer:
(46) Additionally, at the opposite end of slide member 34, handle portion 50 may be configured to firmly fit or snap in place within groove 60, providing another securing mechanism and physical indication of attachment. Both fits are sufficient to hold slide member 34 in its retracted position during normal handling of the firearm and during shooting, but resilient enough to allow for hand release and extension of slide member 34.
(47) In another embodiment slide member 34 may be removably secured to the slide by a magnetic contact 78 located within an aperture 76 of slide 12, or complementary magnetic contacts located respectively on slide member 34 and the slide 12.
(48)
(49)
(50) In a second embodiment, slide member or winged extensions are mounted from the back or breech end of the pistol.
(51)
(52)
(53) Slide member 80 includes a holding or grasping portion 81, which preferably is an approximately flat surface (in the current embodiment, a quasi-rectangular shaped portion) that allows a user to hold the slide member and pull back the slide towards the breech end.
(54) Slide members 80 each have attachment segment 84 that is rotatably held within partially walled aperture 86 in the slide 82. Partially walled aperture 86 extends a portion of the way down from the top surface of the slide, along the slide's side surface. The curved shape of partially walled aperture 86 engulfs a portion of the circumference of the attachment segment 84, which in this example is the preferred cylindrical column 84, thus holding slide member 80 within slide 82. The partially walled aperture does not extend to the bottom of the slide member so that a gap is present to receive the holding portion 81. This configuration secures the slide member to the slide while allowing the slide member to rotate with respect to the slide.
(55) A resilient bias member, such as a spring 88, is used to perform a restoring force to the slide member. The resilient bias member 88 acts to retract an extended slide member back towards the slide. Springs 88 and plungers 90 are inserted from the breech end 94 of slide 82 within apertures 92 that are accessible from breech end 94, and extend to partially walled aperture 86. As will be discussed further herein, resilient bias members 88 provide a retraction or restoration force for open slide members 80 to close, and once closed, to maintain a closing force to ensure each slide member remains within its receiving slot 96 of slide 82. This removes the retraction responsibility from the user, while simultaneously protecting against an inadvertent extension of slide member 80 that could otherwise catch on clothing or other objects.
(56) The receiving slot 96 is an indentation within the slide's side surface, defined by a bottom edge 97a, a breech end side wall 97b, and a muzzle end side wall 97c, formed such that the slide member is received within the receiving slot, and mounts approximately flush with the sidewall surface of the slide.
(57) The slide 82 includes a top segment 93 extending from the upper portion of the slide side surface, which with the breech end side wall 97b of the receiving slot forms the partially walled aperture 86. The partially walled aperture is curved to receive arid hold the cylindrical column 84 of slide member 80. Top segment 93 does not extend to the receiving slot bottom edge 97a. This gap allows for the rotation of slide member 80 relative to the slide side surface.
(58) The user is able to grasp and extend the slide members by sliding fingers along sloped indentations 83 which traverse from the top surface of slide 82 to a point on the side surface of slide 82 just below the top surface of slide member 80. In this manner, the top surface of slide member 80 is readily accessible for quick extension.

(60)
(61)
(62)
(63)
(64)
(65) When in the closed position, the force of spring 88 in the breech direction (toward the breech end of slide 82) holds slide member 80 tightly within receiving slot 96 (not shown), such that any extension of slide member 80 will be against the restoring force, which would tend to close the slide member back within receiving slot 96.
(66)
(67)
(68)
(69)
(70)
(71) Once the plunger peg is aligned and visible within receiving slot 96 and centered about partially walled aperture 86, attachment segment 84 of slide member 80 is inserted within partially walled aperture 86. The attachment segment (cylindrical column) 84 includes a receiving groove or keyway 87 that aligns with plunger peg 95 during insertion. Keyway 87 extends from the bottom of cylindrical column 84 to a center radial groove 89. Keyway 87 is perpendicular to center radial groove 89. As cylindrical column 84 is inserted into partially walled aperture 86, keyway 87 aligns with peg 95.
(72)
(73) The geometry between the slide member and the plunger creates a locking feature such that the slide member cannot come loose, or be pulled out, without first pressing the plunger within aperture 92 deep enough to expose the aligned plunger peg to the hole.
(74) The pistol slide and slide member of the present invention present a unique method for racking the slide. Essentially, a portion of the slide member initially placed in a retracted position is grasped, and the slide member is rotated laterally outwards from a side surface of the slide or vertically upwards from a top surface of the slide, such that said slide member is placed in an extended position. At this point, the slide member is grasped by the shooter, and pulled towards a breech end of the pistol. Upon release, the slide member is restored to its retracted position under spring tension.
(75) In a separate embodiment, a slide member may be top mounted as depicted in
(76)
(77)
(78)
(79) While the present invention has been particularly described, in conjunction with a specific preferred embodiment, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. It is therefore contemplated that the appended claims will embrace any such alternatives, modifications and variations as falling within the true scope and spirit of the present invention.
