Description
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] FIG. 1 shows the Modulus pistol in one possible configuration.
[0012] FIG. 2 shows the Modulus pistol in one possible configuration with the slide and barrel removed.
[0013] FIG. 3 shows the Modulus pistol depicted in FIG. 2 in a partially exploded assembly. Item 1 (Receiver) is mated to Item 3 (Dustcover) via interlocking geometry and fastened into Item 4 (Modular Grip Components) with Item 2 (Screw).
[0014] FIG. 4 depicts the isometric view of the receiver introduces in FIG. 3.
[0015] FIG. 5 shows the sub assembly Item 5 (Modular grip components mated with the receiver).
[0016] FIG. 6 shows an exploded view of a carbine configuration of the Modulus pistol platform. Item 5 (Modular grip components mated with the receiver) is assembled with Item 6 (Mid-Receiver Assembly) and fastened with Item 2 (Screw). Item 7 (Standard AR15 Upper) can then be used to complete the firearm assembly just like it would mate with a standard AR15 Lower.
[0017] FIG. 7 depicts the assembly described in FIG. 6, ready to receive the standard AR15 Upper. Item 6 slides onto Item 5, utilizing the rails originally designed for the slide assembly and is secured with item 2.
[0018] FIG. 8 depicts the assembly described in FIG. 6 as a complete Firearm.
[0019] FIG. 9 is a cross-section through the center of the assembly described in FIG. 6.
[0020] FIG. 10 is a cropped and enlarged view of the cross-section shown in FIG. 9. Area 8 shows a typical striker fire connection in Item 5 (Modular grip components mated with the receiver); however, instead of connecting to a firing pin, area 8 Connects to Item 9 (sled) in Item 6 (Mid-Receiver Assembly). This connection allows for the fire control in Item 5 to operate the firearm. The sled is connected to item 11 (hammer) by item 10 (connector arm), allowing the linear control to be converted into a hammer strike. Item 9, 10, and 11 are housed in Item 12 (mid-receiver body). The Magwell for rifle rounds is built into item 12. In this image, the firing mechanism is shown in the charged or ready-to-fire state.
[0021] FIG. 11 shows the assembly described in FIG. 10 as the hammer is striking the firing pin firing the round.
[0022] FIG. 12 shows the assembly described in FIG. 10 as the carrier is resetting the trigger mechanism.
[0023] FIG. 13 shows Item 6 (Mid-Receiver Assembly) in a cross-section view.
[0024] FIG. 14 shows Item 6 (Mid-Receiver Assembly) in a bottom view, with Item 9 (sled) connected to Item 10 (Connector Arm).
[0025] FIG. 15 shows Item 6 (Mid-Receiver Assembly) in a back view.
[0026] FIG. 16 shows item 6 (Mid-Receiver Assembly) in a partially exploded state. Item 13 (Mid-Receiver Stop) is installed into item 12 (mid-receiver body) to pass recoil into item 5 (Modular grip components mated with the receiver) and act as a stop when installing the mid receiver assembly on to Item 5.
[0027] FIG. 17 show cross-section through Item 6 (Mid-Receiver Assembly). Area 14 shows the groove for mating on the rail in Item 1 (receiver). Area 15 shows the sliding connection between Item 9 (Sled) and Item 12 (Mid receiver Body). The image also shows Item 13 (Mid Receiver Stop) fastened to Item 12 (Mid receiver Body).
[0028] FIG. 18 Shows 3 views of the Item 9 (Sled).
[0029] FIG. 19 shows an isometric view of item 10 (Connector).
[0030] FIG. 20 shows an isometric view of item 9 (Sled).
[0031] FIG. 21 shows an isometric view of item 11 (Hammer).
[0032] FIG. 22 shows an isometric view of item 13 (Mid Receiver Stop).
[0033] FIG. 23 shows an isometric view of item 12 (Mid Receiver Body).
[0034] FIG. 24 depicts Item 5 (Modular grip components mated with the receiver) with Item 16 (pump action shotgun upper assembly) installed.
[0035] FIG. 25 depicts Item 5 (Modular grip components mated with the receiver) with Item 17 (bolt action rifle upper assembly) installed.
[0036] FIG. 26 depicts Item 5 (Modular grip components mated with the receiver) with Item 18 (machine gun upper assembly) installed.
[0037] FIG. 27 shows an optic mount shown in an isometric view.
[0038] FIG. 28 shows an optic mount shown in a rear view.
[0039] FIG. 29 shows an optic mount shown in a side view.
[0040] FIG. 30 shows a cross-section of a mount adapter assembly for an optic. The mount adapter assembly is held onto the rail by spring force pulling the lock bar member towards the main body of the mount. Item 21 (Spring) is captured above the push rod in the Item 19 (main body). The force of the spring is translated through item 20 (Cross set screw).
[0041] FIG. 31 shows a cross-section of the mount adapter assembly when clamped about a rail. The lock bar and the main body are pulled together clamping on the rail. The knob is unscrewed allowing the push rod assembly to move if depressed. Item 22 (Rail) is an example of a rail in which the assembly would mount on.
[0042] FIG. 32 shows an exploded view of a mount adapter assembly. Item 24 (Push Rod) is connected to Item 23 (Lock Bar) in a way that the two items move in and out along the axis of the push rod together. Item 25 (Knob) is threaded on the push rod and can be torqued to add additional clamping force. Item 26 (Guide Pins) are pressed into Item 19 (Main Body) and limit the motion of the lock bar to one direction. Item 19 (Main body) has geometry for fastening and supporting an accessory such as an optic mount. Item 21 (Spring) can be one or multiple springs that apply force into the push rod that is translated to the lock bar to pull the lock bar and main body together to clamp on a rail. The springs are set off axis of the push rod. Item 20 (Cross Set Screw) Is installed through the push rod and connects the spring to the push rod. Item 28 (set screw) is used to secure the push rod to the lock bar.
[0043] FIG. 33 shows an optic mount shown in a bottom view.
[0044] FIG. 34 shows an isometric view of the ambi magazine release assembly. When Item 29 (lever) is depressed item 31 (Catch) is retracted while item 30 (catch plate body) remains stationary. When item 31 is retracted a magazine can be removed from the magwell. The entire assembly would move when the traditional AR15 mag release button is depressed.
[0045] FIG. 35 shows a cross-section of the ambi magazine release assembly depicting Item 29 pinned to item 30 able to pivot to retract item 31.
[0046] FIG. 36 shows an exploded view of the ambi magazine release assembly.
