Patent number: 11262159Abstract: The present disclosure describes a foldable firearm that collapses into a folded state under spring pressure. The foldable firearm may include a foldable grip assembly. The foldable grip assembly may include a foldable pistol grip, a foldable trigger assembly, a folding bar, and a foldable hand stop. The foldable grip assembly may fold into the top shell of the foldable firearm. The foldable firearm may also include an ambidextrous charging handle assembly that may include a bottom portion, a top portion, a guide bar, and two opposing charging handles. The charging handles may be pulled to unfold the foldable firearm, and/or butterflied such that pivoting one charging handle causes the other charging handle to pivot. The first-pivoted charging handle may then be pulled rearwards to unfold the firearm. The first-pivoted charging handle may then be pulled further rearwards to rack the slide of the foldable firearm.Type: GrantFiled: December 16, 2020Date of Patent: March 1, 2022Assignee: Magpul Industries Corp.Inventors: Nicholas Kielsmeier, Brian L. Nakayama, Jeremy M. Fiester, Michael T. Mayberry

Publication number: 20210331335Abstract: This disclosure describes systems, methods, and apparatus for a locking folding knife having a handle lock and a safety switch arranged around and rotatable around a pivot axis of the knife. In an engaged position the switch overlaps at least a portion of the handle lock and prevents it from moving into an unlocked position. A spring, such as a wire form spring, can be arranged within a pocket of the switch, and when the switch is moved between engaged and disengaged positions the spring can be compressed generating a rotational bias on the switch urging the switch toward either the engaged or disengaged position.Type: ApplicationFiled: June 7, 2021Publication date: October 28, 2021Inventors: Michael T. Mayberry, Danny R. Smith, Thomas Ward, Deniece Hopkins, Timothy Eric Roberts, Timothy James Galyean

Publication number: 20210302123Abstract: An accessory mounting interface for a firearm, and a related method, are disclosed. The interface has a firearm accessory, a first elongated fastener, and a second fastener rotationally mated to the first elongated fastener. The first elongated fastener has right-handed threading and is arranged through a through hole in the firearm accessory with a first end extending below first and second halves of a first slot protrusion of the firearm accessory. The second fastener has a length greater than a width, the length measured along a longitudinal axis of the second fastener, the second fastener having a plurality of straight edges. At least one of the plurality of straight edges prevents the second fastener from rotating further than a closed position when the at least one of the straight edges abuts a sidewall of an elongated slot in the firearm.Type: ApplicationFiled: April 8, 2021Publication date: September 30, 2021Inventors: Michael T.

Patent number: 10849390Abstract: Disclosed is a closure system used in combination in any of a variety of applications including clothing, for example as a footwear lacing system comprising a lace attached to a tightening mechanism. The lace extends through a series of guide members positioned along two opposing footwear closure portions. The lace and guides preferably have low friction surfaces to facilitate sliding of the lace along the guide members so that the lace evenly distributes tension across the footwear member. The tightening mechanism allows incremental adjustment of the tension of the lace. The closure system allows a user to quickly loosen the lace and inhibits unintentional and/or accidental loosing of the lace.Type: GrantFiled: January 12, 2018Date of Patent: December 1, 2020Assignee: Boa Technology Inc.Inventors: Gary Hammerslag, Mark Soderberg, Michael T.

Patent number: 10739100Abstract: This disclosure describes systems, methods, and apparatus for a bipod having pivot and cant functionality built into a unified cant/pivot assembly, housing, and pivot block. Rotation of a locking knob under the housing can gradually increase or decrease friction of the cant and pivoting degrees of freedom. The legs can be stowed approximately 90° rotation from a deployed position, and locking and releasing of this rotation is made possible via depression of a button that also acts as a locking detent that directly interacts with and locks or releases the legs for rotation. In the stowed position, the button can be backdriven and thus the legs can be deployed without depressing the button. A pivot block can also be raised and rotated 180° to lock in a given pivot setting.Type: GrantFiled: November 16, 2018Date of Patent: August 11, 2020Assignee: Magpul Industries Corp.Inventors: Timothy Eric Roberts, Michael T.
