Patent number: 10794661Abstract: A collapsible buttstock with automatic deployment has a housing with an opening providing clearance for a buffer tube. Rods slidably couple through respective openings in the housing; the rods each having a hollow cavity accommodating biasing structure for exerting a biasing force against a respective attachment member. A locking element has locking blocks, each engaging a respective one of plural notches on the rods, for locking the rods to an operator support buttstock element, each of the locking blocks comprising a tapered surface. A release trigger with a contoured step engages the tapered surfaces of the locking blocks. When the release trigger is moved, the contoured step engages the tapered surfaces to push locking blocks away from engagement with the notches on the rods, thus allowing the biasing member in each rod to push the respective rod and the operator support buttstock element away from the housing.Type: GrantFiled: July 21, 2016Date of Patent: October 6, 2020Inventors: Robert Irvin, George W. Bush, Samer Alkhalaileh, Joshua K. Cox

Patent number: 10345060Abstract: A buffer tube for firearms, including assault rifles, carbines, shotguns, and other rifles is disclosed. The floating buffer tube comprises a recoil mitigation mechanism, including a helical spring or an elastic or viscous energy absorption device, and a buttstock mounting bracket mounted outside the buffer tube. The buttstock mounting bracket can rotate relative to the buffer tube, which changes the axial angle of the buttstock relative to the firearm. The angle can be locked under an expansive force by forcing a bolt or pin into grooves to select the proper axial angle of the buttstock relative to the firearm in the field without the user having to disarm himself to perform the angle change.Type: GrantFiled: March 19, 2015Date of Patent: July 9, 2019Assignee: Suzhou Superior Industrial Technology Co., Ltd.Inventor: Robert Irvin

Publication number: 20020090511Abstract: The present invention provides cellulose fibers having low median desorption pressures and low water retention values (WRV), which exhibit improved drainage and fluid flow properties. These fibers are particularly well suited for use in acquisition, distribution, and acquisition-distribution layers, or in absorbent core structures. One embodiment of the invention is a method for preparing cellulose fibers by refining cellulose fibers to a freeness ranging from about 300 to about 700 ml CSF and crosslinking the refined fibers. Another embodiment of the invention is fibers crosslinked with at least one saturated dicarboxylic acid, aromatic dicarboxylic acid, cycloalkyl discarboxylic acid, bifunctional monocarboxylic acid, or amine carboxylic acid. A crosslinking facilitator, such as oxalic acid, may be present during the crosslinking reaction to improve the efficacy of the crosslinking agent. Yet another embodiment of the invention is an absorbent core comprising SAP particles and reversible crosslinked fibers.Type: ApplicationFiled: November 8, 2001Publication date: July 11, 2002Applicant: BKI HOLDING CORPORATIONInventors: David Jay Smith, Howard Leon Schoggen, Robert Irvin Bell, James R.
