A dual safety mechanism avoids unintentional release. A streamlined design minimizes the potential for catching foreign objects.

Description

    FIELD OF THE INVENTION
  • This disclosure relates to mechanisms for releasable mounting of various devices on a support structure, and, more particularly, to mechanisms for facilitating the quick and secure assembly and disassembly of firearm accessories onto a rail system.
  • BACKGROUND OF THE INVENTION
  • As the field of combat and commercial weaponry expands, numerous add-on enhancements or accessories have become available for attachment to basic models. Firearms such as the M-16/M4 and AR-15 rifles, as well as their numerous variants, are often used with accessories such as bipods, scopes, sights, lasers, and lighting devices. Typically, such accessories are associated with the firearm via one or more rails positioned below, above or on the sides of the barrel. Such a rail may include a number of mounting projections interleaved with a series of grooves, and these mounting projections and grooves may be employed to associate the accessory with the rail.
  • Rails usually conform to certain standards. For example, two common rails include the “Picatinny” MIL-STD 1913 rail and the “Weaver” rail; both include interleaved mounting projections and grooves, but differ in dimension.
  • Firearm accessories have historically been mounted by means of mounting screws. This is typically referred to as a permanent mount since the accessory will typically remain assembled to the firearm until the end of a mission. Because various missions often require a different set of accessories, there is a need for versatile and reliable quick-disconnect (QD) attachment mechanisms, also known as “throw lever” mechanisms. This is especially important when in-the-field modification of a weapon configuration is necessary, and can be absolutely critical in combat situations.
  • As the name indicates, quick disconnects enable the quick disconnect from the mount. However the initial connection to a specific rail requires an initial adjustment. Subsequent connections are then quick. Such adjustment provides the user with a means to compensate for the rails dimensional tolerances, which can vary from rail to rail and even from position to position on the same rail.
  • A typical throw lever includes a fixed mount portion and a lever arm portion. The lever arm portion may be actuated to selectively clamp the throw lever to the rail, or to release the throw lever from the rail. However, there are several types of QD mechanisms.
  • In one type, the lever arm portion may indirectly act on the clamping portion via an intervening cam. The cam may then transfer the movement of the lever arm portion to the clamping portion, forcing the clamping portion into abutment against the rail. Systems of this type often have a fixed mount with 2 clamping surfaces and a movable clamp with two clamping surfaces. Commercially available examples include products from American Defense Manufacturing and Daniel Defense.
  • In another type, the lever arm portion of the throw lever may directly move the clamping portion into abutment against the rail. Systems of this type often have a fixed mount portion with 3 clamping surfaces and a movable clamp with one clamping surface. Commercially available examples include products from LaRue and ARMS. U.S. Pat. Nos. 4,845,871 and 5,276,988 of Swan as well as U.S. Pat. No. 7,272,904 B2 and 2014/0082985 A1 of LaRue also describe such mounting systems. They are, however, more complicated to manufacture and involve more parts than are necessary to achieve the desired functionality.
  • While the tension of the clamping assembly is normally adequate to retain the actuator arm in the engaged position, one problem with throw levers is that if the firearm is subject to sustained vibrations from transport or rapid fire, or if the lever arm snags against an external object, the throw lever may loosen. This can cause the mount to shift, which can be especially detrimental for sighting devices, such as optics or lasers, where it will result in the aim-point of a sighting device being lost. In other instances, the throw lever may even rotate after loosening, resulting in dislodgement of the mount and the attached accessory from the weapon. For this reason, some firearm operators take the precaution of tethering the accessory to the firearm using a string, so that the accessory is not lost if the throw lever opens.
  • U.S. Pat. No. 2006/0207156 A1 to LaRue discloses a lever safety latch. However this safety latch may be accidentally released by friction or direct shock.
  • Furthermore, many existing quick-disconnect mounts define projecting components that tend to catch on various objects or vegetation as a firearm is being carried by a user.
  • What is needed, therefore, are quick-disconnect mounts that include a latching system allowing for adjustment to accommodate various rails of slightly differing dimensions, adequately prevent accidental rotation of the actuator arm even under the harshest operating conditions and minimize the potential for catching and becoming tangled during use.

  • DETAILED DESCRIPTION
  • It is an object of the present disclosure to provide a mechanism for facilitating the quick assembly and disassembly of accessories onto a rail that is more cost effective to manufacture.
  • It is another object of the present disclosure to provide a quick-disconnect mechanism that provides enhanced features against accidental release of the mechanism.
  • It is yet another object of the present disclosure to provide an accessory mount mechanism that eliminates or minimizes the potential for catching foreign objects and becoming tangled.
  • The present disclosure provides a quick-disconnect mounting system for MIL 1913 Picatinny and NATO Accessory Rail Stanag 4694 rail systems commonly used on modular weapons systems. The teachings of this disclosure, however, shall not be limited to firearms or to the specific aforementioned rail specification, as embodiments of the present disclosure may readily be adapted for use in conjunction with photographic and video equipment as well as for other applications.
  • Embodiments of the present disclosure provide an adjustable, rotatable, locking lever actuated clamp mechanism, also known as a throw-lever clamping system, for the quick assembly and disassembly of firearm accessories such as aiming devices, laser illumination devices, lighting devices and bipods onto a firearm mount rail. Embodiments also provide locking or latching systems for positively maintaining throw-levers in a closed clamping position to prevent inadvertent opening due to firearm handling in rough field conditions such as sustained vibrations, shocks and friction with clothing, walls or terrain.
  • Notable improvements over the prior art include a dual safety mechanism to prevent unintentional release and a streamlined design to minimize the potential for catching or snagging on foreign objects.
  • Now referring to FIGS. 1-6, which illustrate the assembly of the present disclosure according to a first embodiment. The present disclosure comprises two mechanisms: a locking lever mechanism and a safety latch mechanism.
  • Now referring to FIG. 1, a perspective view of the present disclosure, assembled onto a rail 8 is shown. Rail 8 has four oppositely angulated clamping surfaces 80, defining a generally elongated hexagon with three pairs of parallel sides (2 trapezoids sharing the long side) mating surface for accessories.
  • Now referring to FIGS. 2A and 2B, an exploded perspective view of the locking lever mechanism of the present disclosure is shown. Notably, the locking lever mechanism only requires four components: a mounting base 1, a locking lever 2, a resilient member 3 and an adjustment member 4. The resilient member 3 may be in the form of a circular wave spring or other suitable device. The adjustment member 4 may be in the form of a screw, shoulder screw, bolt, thumbscrew or the like.
  • The mounting base 1 may further comprise a lever pivot cylinder opening 12, which may advantageously be of a generally cylindrical shape. The locking lever 2, in embodiments, further comprises a pivot cylinder 21 suitable for insertion into said lever pivot cylinder opening. The pivot cylinder 21 and the lever pivot cylinder opening 12 are designed for a close fit while still enabling rotation therebetween. Relief cuts and grooves in the lever pivot cylinder opening 12 and/or pivot cylinder 21 may be added to allow for debris to escape without exceeding the scope of the disclosure.
  • The retention member 4 may be threaded in the locking lever's threaded hole 22 (depicted in FIG. 4). Alternate methods of establishing adjustment of a retention member 4 are assumed to be known to those of ordinary skill in the art.
  • The mounting base 1, in embodiments and when used in conjunction with MIL 1913 Picatinny rail systems, may have 3 angulated clamping surfaces 10 dimensioned to mate with 3 of the rail's surfaces 80. When designed for the NATO Accessory Rail Stanag 4694 system, the mounting base would clamp against a different set of rail surfaces.
  • The resilient member 3, in embodiments, is mounted so as to bias the locking lever 2 towards mounting base 1, as shown in FIG. 2B.
  • Variation in rails 8 may be compensated for by adjustment of retention member 4. Once the position of retention member 4 yielding the desired clamping force has been determined, it is important that the retention member 4 does not rotate in relation to the locking lever 2 when the locking lever 2 rotates around the mounting base 1. To achieve this, the retention member 4 may be bonded with an adhesive (not shown) into the locking lever's threaded hole 22. To enable the later adjustment for use with other rails, a non-permanent adhesive should be used. A non-permanent adhesive, for the purposes of this specification should be considered an adhesive whose strength is enough to resist the friction force of the resilient member 3 against the retention member 4, but whose strength is weak enough so as to enable the bond to be broken through the use of a tool such as a wrench to unscrew the retention member 4. Alternatively, or jointly, an interference fit may be implemented between the retention member 4 and the locking lever's threaded hole 22. Alternatively, resilient member 3 may be designed so as to have enough travel amplitude to compensate for dimensional tolerances in rails 8 while providing adequate clamping force and a shoulder screw may be used as retention member 4.
  • Now referring to FIG. 4, a perspective view of the locking lever 2 is shown. The locking lever 2 features a peripheral angulated cam surface 28. This surface, in embodiments, comprises a long straight section 20 designed to contact the fourth oppositely angulated clamping surface 80 (the one that is not in contact with the mounting base 1) and a short straight section 24. The distance from the locking lever's axis to the long straight section 20 is greater than the distance to the short straight section 24 to enable engagement and disengagement from rail 8.
  • The locking lever 2 may also, in embodiments, feature a safety latch cavity 25. The safety latch cavity 25 also has a latch head well 26 that may be cylindrical as in this disclosure but may also be of any different shape without exceeding the scope of the present disclosure. These features are used for the safety latch mechanism.
  • The locking lever 2 is said to be in clamping position when the long straight section 24 contacts a rail clamping surface 80. The locking lever 2 is said to be in release position when the locking lever has rotated away from the clamping position.
  • Now referring to FIG. 3A and 3B, exploded perspective views of both the locking lever mechanism and the safety latch mechanism in accordance with embodiments of the present invention are shown. The safety latch mechanism comprises three further components: a safety latch 5, a resilient member 6 and a safety latch head 7, as well as an additional feature in the mounting base 1: safety latch cavity 14.
  • The resilient member 6 may be in the form of a circular wave spring or other suitable biasing device. The safety latch head 7 may be in the form of a screw and may be screwed to safety latch 5 or otherwise attached to it by any other suitable means.
  • The resilient member 6 is mounted so as to push the safety latch 5 away from the mounting base 1, as shown in section views 5 and perspective section views 6.
  • The safety latch 5 is said to be in latched position when the safety latch head 7 prevents the locking lever 2 from rotating. The safety latch 5 is said to be in open position when the safety latch 5 is depressed, allowing the locking lever 2 to be rotated.
  • Now referring to FIG. 5A, 5B and 5C, section views of the safety latch mechanism of the present disclosure in accordance with embodiments of the present invention are shown. In FIG. 5A the safety latch 5 is in latched position and the locking lever 2 is in clamping position (mount rail 8 is clamped). This is the default spring-loaded position of the safety latch mechanism. In this position the locking lever 2 cannot rotate due to an interfering relationship between the head of the latch lever head 7 and the latch head well 26.
  • In FIG. 5B the safety latch 5 is shown in an open position (the locking lever 2 may rotate) and the locking lever 2 is in clamping position (mount rail 8 is clamped). In this position the locking lever 2 may rotate because the head of the latch lever head 7 has been pushed above the latch head well 26. To be in this position, the safety latch must be pushed by the user. The user must keep applying pressure on the safety latch 5 to initiate the rotation of the locking lever 2. In this sense, a double safety mechanism is thereby created.
  • In FIG. 5C the locking lever 2 is in a release position; the mount may be removed from rail 8 when configured in this manner. In this view it will be apparent to those of ordinary skill in the art why the peripheral angulated cam surface 28 must have a short straight section 24. When the locking lever 2 is in a release position, the user may ease pressure on the safety latch 5. To close the locking lever 2, the user must push the safety latch 5, complete the rotation, then release the safety latch 5 over the latch head well 26.
  • Now referring to FIG. 6A, 6B and 6C, perspective section views of the safety latch mechanism in accordance with embodiments of the present disclosure are shown.
  • Now referring to FIG. 7, a second embodiment that shares the same locking lever assembly mechanism with the first and third embodiments but features a different safety latch 5 as well as a different latching mechanism is illustrated. In this embodiment the mounting base features a locking member 18 that the safety latch 5 engages to prevent accidental rotation of the locking lever 2.
  • FIG. 7A shows the safety latch 5 in latched position and locking lever 2 in a clamped position.
  • FIG. 7B and 7D show the safety latch 5 in an open position, with the locking lever 2 still in a clamped position.
  • FIGS. 7C, 7F and 7E show the safety latch 5 in an open position and locking lever 2 in a release position. In this position the rail 8 may be disengaged.
  • In the second embodiment described above, and unlike the first embodiments previously described and third embodiments yet to be described, the safety latch is not spring loaded. Instead, it may be indexed with a ball plunger (not shown) in either the latched or open position.
  • Now referring to FIG. 8A-8E, a third embodiment, which differs from the first embodiment primarily in that the safety latch 5 is integral to the locking lever 2, and not to the mounting base 1 as is the case with the first embodiment, is illustrated.
  • As shown in FIG. 8E the mounting base 1 may feature a locking member 19.
  • As shown in FIG. 8D the locking lever 2 may feature a safety latch hole 27.
  • As with the first embodiment, the user must apply pressure on the safety latch 5 to initiate rotation of locking lever 2, preventing accidental loosening of the quick-disconnect mount. Once the locking lever has rotated away from the safety latch adjustment member 7, the user may ease pressure on the safety latch 5. To close the locking lever 2, the user must push the safety latch 5, complete the rotation, then release the safety latch 5.
  • Now referring to FIGS. 9A-9G various embodiments of the accessory facing side of the mounting base 1 are illustrated.
  • As depicted in FIG. 9A, the accessory facing side, in embodiments, may be flat and feature any number of accessory mounting holes 16.
  • As depicted in FIG. 9B, the accessory facing side may provide a cut-off feature 15 in the form of a groove as well as any number of accessory mounting holes 16.
  • As depicted in FIG. 9C, the accessory facing side may provide any number of accessory mounting projections 17, for instance to mount sighting devices.
  • As depicted in FIG. 9D, the accessory facing side may provide a cylindrical accessory mounting projection 17 that would enable the accessory to rotate around the axis of said projection.
  • As depicted in FIG. 9E, the accessory facing side may provide any number of accessory mounting projections 17 that would enable the accessory to pivot to the side of the firearm.
  • As depicted in FIG. 9F, the accessory facing side may provide a concave cut-off feature 15 as well as any number of accessory mounting holes 16.
  • As depicted in FIG. 9G, the accessory facing side may provide a cylindrical accessory mounting cavity 13 that would enable the accessory to rotate around the axis of said cavity.
  • The locking lever 2 may also be located on the accessory side of the mounting base 1, instead of the rail side as is the case in the first, second and third embodiments previously described, without departing from the intended scope of the present invention.
  • The foregoing description of the embodiments of the disclosure has been presented for the purposes of illustration and description. Each and every page of this submission, and all contents thereon, however characterized, identified, or numbered, is considered a substantive part of this application for all purposes, irrespective of form or placement within the application. This specification is not intended to be exhaustive or to limit the disclosure to the precise form disclosed. Many modifications and variations are possible in light of this disclosure.
