Snap-In Pivot Pin For Universal Joints
US Patent:
2010020, Aug 12, 2010
Filed:
Feb 1, 2010
Appl. No.:
12/697668
Inventors:
Brian Bentrim - Furlong PA, US
Assignee:
PEM MANAGEMENT, INC. - Wilmington DE
International Classification:
F16C 11/06
US Classification:
403163
Abstract:
A universal joint employs snap-in press pins to rotatably secure the center knuckle with the surrounding drive shaft cup providing a simplified assembly process. The press pins install flush or sub-flush with the outside of the steering shaft cup. A snap-lock feature permits one-direction axial movement only. Each snap pin includes a barb-like tapered flange with a lead-in ramp to aid installation. Once installed, a radially extending base on the backside of the flange abuts the inside wall of the drive shaft cup.
Quick Acting Panel Fastener
US Patent:
2011002, Jan 27, 2011
Filed:
Jul 23, 2010
Appl. No.:
12/842214
Inventors:
Brian Bentrim - Furlong PA, US
Michael Maloney - Doylestown PA, US
Michael Maloney - Doylestown PA, US
Assignee:
PEM MANAGEMENT, INC. - Wilmington DE
International Classification:
F16B 21/07, F16B 21/18
US Classification:
411352, 411337
Abstract:
A panel fastener is comprised of two separately formed interacting parts: a panel retainer and an actuator pin. The retainer is fashioned from sheet metal using progressive stamping technology. The retainer and pin work together to create a fastener for securing two panels together that can semi-permanently snap into the first panel and then be clamped onto and then selectively removed from the second panel. Attachment to the second panel is obtained by expanding and later released by contracting the legs of the retainer by rotating a cammed expander pin between self-locking positions. A head of the expander pin can be configured for hand actuation, tool-only actuation, or both. The retainer is fashioned from sheet metal using progressive stamping technology.
Rotatable Captivated Nut
US Patent:
8021091, Sep 20, 2011
Filed:
May 12, 2008
Appl. No.:
12/119000
Inventors:
Brian G. Bentrim - Furlong PA, US
Assignee:
PEM Management, Inc. - Wilmington DE
International Classification:
F16B 37/04
US Classification:
411180, 411533
Abstract:
A rotatably captive clinch nut includes a body having an axial threaded bore and a flange forming a base of the nut body. The flange includes a surface on a bottom side thereof preferably unitary therewith for providing a bearing surface of reduced friction. A displacer unitary with the nut body is located directly below the flange and has an outside diameter less than an outside diameter of the flange. A tubular flared shank unitary with the nut body extends coaxially from the displacer and includes a neck immediately adjacent the displacer, forming an undercut area between the outside of the shank and an underside of the displacer. The neck may include an axially extending cylindrical portion so that the thickness of the displaced material in the region of the undercut is substantially less than the axial length of the nut.
Window Glass Mounted Fastener
US Patent:
2012021, Aug 23, 2012
Filed:
Feb 17, 2012
Appl. No.:
13/398928
Inventors:
Brian Bentrim - Furlong PA, US
Assignee:
PEM MANAGEMENT, INC. - Wilmington DE
International Classification:
H05K 5/02, H05K 5/00
US Classification:
3122234, 3122231
Abstract:
A soldered fastening device mounts a glass plate to a support structure, for example, a window glass mounted to the housing of an electronic device such as a cell phone. The fastening device affixed to a rear surface of the window by solder threadably engages a housing fastener to rigidly secure the window to the housing. The soldering process is preferably wave soldering and the fastening device can have an internally threaded axial bore which is either perpendicular to or parallel to the surface of the window for receiving the fastener, such as a screw.
Plastic-Metal Hybrid Standoff
US Patent:
8083452, Dec 27, 2011
Filed:
Apr 8, 2009
Appl. No.:
12/420393
Inventors:
Brian Bentrim - Furlong PA, US
Assignee:
PEM Management, Inc. - Wilmington DE
International Classification:
F16B 37/04
US Classification:
411180, 411103, 411108, 411190, 411259, 411301, 411427, 411432, 411531, 411533, 411900, 411901, 411902, 411903, 411904, 411908
Abstract:
A hybrid clinch-type standoff consists of two component parts, a metal core base and a overmolded plastic barrel. The base has a through-bore and a displacer flange at the bottom. A first undercut is located immediately above the flange and extends upwardly along an outside surface of the base for providing clinch attachment of the base to a substrate. A frustoconical ramp convergent in the upward direction lies along the outer surface of the base is and is located directly above the first undercut. An axially extending segmented ring with circumferential teeth is located at the top of the base. The overmolded plastic tubular barrel composed of plastic fills the second undercut and surrounds the segmented ring. The barrel has an inner portion including a threaded inner wall which extends downardly inside the through-bore to a point flush with the bottom of the flange.
Snap-In Pivot Pin For Universal Joints
US Patent:
8113962, Feb 14, 2012
Filed:
Mar 12, 2010
Appl. No.:
12/723222
Inventors:
Brian Bentrim - Furlong PA, US
Assignee:
PEM Management, Inc. - Wilmington DE
International Classification:
F16D 3/27
US Classification:
464125, 464112, 464136
Abstract:
A universal joint employs snap-in press pins to rotatably secure the center knuckle with the surrounding drive shaft cup providing a simplified assembly process. The press pins install flush or sub-flush with the outside of the steering shaft cup. A snap-lock feature permits one-direction axial movement only. Each snap pin includes a barb-like tapered flange with a lead-in ramp to aid installation. Once installed, a radially extending base on the backside of the flange abuts the inside wall of the drive shaft cup. A locking clip may be employed to prevent removal of the snap pin. The locking clip includes two axially extending legs with barbs located at the end of each leg, said legs being resiliently biased outwardly and abutting an inside wall of said drive shaft cup when fully engaged with the pin.
Method Of Manufacture For A Plastic-Capped Panel Fastener
US Patent:
8161616, Apr 24, 2012
Filed:
Sep 23, 2010
Appl. No.:
12/888624
Inventors:
Brian G. Bentrim - Furlong PA, US
David Bruno - Doylestown PA, US
David Bruno - Doylestown PA, US
Assignee:
PEM Management, Inc. - Wilmington DE
International Classification:
B21D 39/00
US Classification:
29447, 29509, 2952502, 2952511, 295271, 411999
Abstract:
A captive panel fastener is manufactured by first overmolding a plastic cap around the head of a screw, the cap having a cylindrical plastic skirt extending downwardly beyond the base of the screw head and formed with a circular opening at the bottom. After a compression spring is placed around the shank of the screw, the screw is pressed against a top surface of a ferrule to a point where the capped-skirt extends downwardly below a ferrule flange. At that point, heat and pressure are applied radially inwardly around the periphery of the plastic skirt along its bottom edge until it is permanently deformed to a point where the bottom of the skirt is smaller in diameter than the ferrule flange. The screw is thereby captivated to the ferrule between extended and retracted positions.
