Publication number: 20220243760Abstract: A ball stud assembly includes a ball stud for engaging a component with a stepped bore extending along a bore axis and a reaction surface orthogonal to the bore axis. The stud includes a ball first end, a threaded second end, and a flange. The stud additionally includes a shank extending along a stud axis between the first and second ends, having a stepped shank shape, and configured to extend through the stepped bore and leave a gap between the bore and the shank. The stud also includes a flange between the first end and the shank with a flange surface orthogonal to the stud axis for engaging and abutting the reaction surface. The stud additionally includes a sleeve positioned on the shank and a threaded nut configured to tighten the stud on the component and deform the sleeve such that the sleeve fills at least part of the gap.Type: ApplicationFiled: January 28, 2022Publication date: August 4, 2022Applicant: Acument Intellectual Properties, LLCInventors: Paul Purdy, Gary Sifferman

Patent number: 11378112Abstract: A bolted joint providing a “zero-clearance” fit formed from a bolt including a shoulder that works during installation to cold form a deformable sleeve. The bolted joint joins a bolt receiving member to a clamped component. One or more bolted joints may be used and as the bolts are installed, shoulders on each of the bolts dilate deformable sleeves until the outer diameters of the sleeves contact internal walls of through holes in the clamped component. Each of the deformable sleeves includes at least one groove or flute on its interior surface that results in: reduced radial load on internal walls of the clamped component and the bolt receiving members, and less friction between the sleeve and both the clamped component and a counter bore disposed within the bolt receiving member, thereby allowing for smaller percentage of the bolt's tensile strength capability required to deform the sleeve.Type: GrantFiled: March 12, 2020Date of Patent: July 5, 2022Assignee: Acument Intellectual Properties, LLCInventors: Gary Sifferman, Paul Purdy

Patent number: 11371544Abstract: A fastener system that includes a fastener, a compression-limiting sleeve, and a retainer which generally retains the compression-limiting sleeve on the fastener. By providing that the compression-limiting sleeve is not staked to the fastener, existing technology can be used, and no extra staking processing step needs to be performed. The fastener may comprise a conventional metal threaded screw or bolt, possibly having a recess in its head for receiving a driver. Preferably, the compression-limiting sleeve is cold headed as opposed to being stamped, and preferably includes a counter bore which assures that an end of the retainer is below an end surface of the compression-limiting sleeve. Preferably, the retainer is formed of a thermoplastic elastomer or another suitable material.Type: GrantFiled: December 5, 2019Date of Patent: June 28, 2022Assignee: Acument Intellectual Properties, LLCInventors: Jeramiah Slater, Robert A. Niec, Paul Purdy, Gary Sifferman

Publication number: 20110027046Abstract: A threaded insert which has a cutting edge on its external surface. The cutting edge is configured to punch a hole in a workpiece while leaving a slug intact, still connected to the workpiece structure. The cutting edge is configured such that no backup die need be utilized to form the hole in the workpiece. The threaded insert includes an internal threaded portion, and a deformable side wall which is configured to deform upon installation of the threaded insert, to forming a blind-side bulb against the workpiece, and against the slug. The threaded insert is configured such that an installation tool can be threaded into the threaded insert, the threaded insert pierced through the workpiece. Then, the installation tool is actuated to cause the deformable side wall of the threaded insert to plastically deform and form the blind-side bulb.Type: ApplicationFiled: October 12, 2010Publication date: February 3, 2011Inventors: Victor Lanni, Paul Purdy

Publication number: 20100250385Abstract: A voucher system for redeeming vouchers via a network. The voucher has an associated voucher code that permits access to one or more first items and/or one or more second items. A redemption module accepts a voucher code such that a user, upon validation of the voucher code, selects one or more of the first items and/or selects one or more of the second items. Upon redeeming the voucher, the user receives the selected first items at a designated user account and receives the selected second items at a designated user account.Type: ApplicationFiled: March 31, 2009Publication date: September 30, 2010Inventors: Eric Lempel, Jennifer Cho, Paul Purdy

Publication number: 20070273255Abstract: A storage unit having a frame, drawers and a carrying handle. When the unit is lifted by the handle, or the handle is moved to a position suitable for lifting the storage unit, the handle arms lift the bottom drawer of the stack of drawers which in turn lifts each of the above drawers relative to the frame. As each drawer rises, the clearance gap between adjacent drawers is reduced and the drawers are moved to a locked position where they are blocked by detents mounted on the inside of the frame. In an alternative embodiment (not shown), the handle is coupled to drawer locking slides instead of the bottom drawer and detents on the drawer locking slides engage with the drawers to lock them in the closed position as the drawer locking slides are moved relative to the frame.Type: ApplicationFiled: June 24, 2005Publication date: November 29, 2007Inventor: Paul Purdy

Publication number: 20070234547Abstract: A self-piercing pin and method of installing same. The pin includes a body portion, a pierce ring, a flange, and a lock groove which is disposed between the pierce ring and the flange. An angled surface is provided between the pierce ring and the lock groove. A top side of the flange is generally flat so that the flange can be set flush to the workpiece, and to enhance the side load strength of the pin once the pin is installed. A bottom side of the flange is beveled, angled or flat, thereby minimizing the amount of workpiece material which becomes displaced during installation. Upon installation, the pierce ring shears the workpiece, and the material of workpiece flows to the lock groove portion of the pin, thereby forming a mechanical lock between the pin and the workpiece. A driver and a die are used to install the pin.Type: ApplicationFiled: April 10, 2007Publication date: October 11, 2007Applicant: ACUMENT INTELLECTUAL PROPERTIES, LLCInventors: Victor A.
