Filed:

Oct 6, 2005

Appl. No.:

11/163138

Inventors:

Michael J Maloney - Doylestown PA, US

Assignee:

PEM Management, Inc, - Wilmington DE

International Classification:

F16B 37/04
F16B 19/08

US Classification:

411180, 411501, 4034081

Abstract:

A double flush clinch stud includes adjacent clinch means of different diameters with planar end surfaces. The stud may be employed in forming an assembly wherein two metal sheets are joined in face-to-face contacting relationship. This assembly can provide a flush attachment on the outside surfaces of both sheets when the length of the stud is equal to the combined widths of the sheets. In an alternative embodiment, the top undercut groove can be adapted to be underfilled with the material of the top sheet. In this alternate configuration, the top sheet is effectively constrained between the head of the fastener and the second sheet while permitting the top sheet to pivot with respect to the second sheet.

US Classification:

411180, 411500, 411501

Abstract:

A connector insert is installed into two panels, one non-metallic and one metal, effectively locking them together and finishing flush with the surfaces of each panel. Both sheets have aligned apertures through which the connector is installed. The connector is a clinch-type fastener including a shank having a displacer head at one end and an endface at the opposite end, the head having a planar top surface and being the largest diameter of the fastener. An undercut groove is located on the shank immediately below the head and a plurality of axially-extending broaching teeth on the shank are located immediately below the undercut groove. The diameter of the broaching teeth is greater than the diameter of the undercut groove but less than the diameter of the head. At the end of the shank is a planar endface immediately below the broaching portion.

US Classification:

384439, 384518, 384537, 403163

Abstract:

The rotatable joinder of two sheets is provided by a two-piece interfitting bearing assembly with each element separately attached to one of the sheets so that the sheets are joined but rotation is controlled by the interfitting bearing surfaces. The interfitting parts comprise an inner and outer race which are placed together in superposition with aligned apertures in the sheets. The rotatable attachment of the sheets is accomplished in a single pressing operation in which each race is simultaneously pressed into one of the sheets with a gap remaining between them.

International Classification:

H05K 7/20

US Classification:

361719, 361697, 361694, 361695

Abstract:

A fastening system for a heat sink mounted on a circuit board utilizes a self-clinching stud assembly constructed by axially interfitting two flat sheet metal members. Each member has forked ends which when axially plugged together in criss-cross fashion create a unified fastener with side structures that can permanently clinch into a heat sink. After attachment to the heat sink, the stud presents two opposite attachment ends with tines which extend from the top and bottom of the heat sink. As finally assembled, a fan attaches to the top end of the studs above the heat sink while the opposite end of the stud which extends from the bottom of the heat sink passes through the circuit board to attach to a retaining leaf spring which presses against the back side of the board. Thus, all of the components are joined by a single stud.

Assignee:

PEM Management, Inc. - Wilmington DE

International Classification:

F16B 21/00

US Classification:

411339, 411501

Abstract:

A clinch-type fastener is formed by simultaneously creating an undercut during the same forging that creates the head and displacer of the fastener. A fastener blank is compressed end-to-end between top and bottom dies whereby the axial compression of a blank causes the outward bulging of the shank at its midline. Simultaneously, a tapered end point and a tangential interference band are formed provided by a curvilinear-shaped bulge in the shank. As the bulge is formed an undercut is created between the bulge and a shoulder which extends downwardly from a head of the fastener. This method of formation and the fastener produced thereby are particularly suited to the manufacture of small clinch pins having a diameter in the range of 1. 0 mm.

Assignee:

PEM Management, Inc. - Wilmington DE

International Classification:

F16H 25/16

US Classification:

74640

Abstract:

The present invention permits linear slide motion as well as rotational motion between two sheets or panels of metal. This linear rail system utilizes clinching end stays to hold a loop of wire taut in a milled or stamped slot in a sheet metal panel. The loop of wire is stretched in the milled slot, being wrapped through the undercuts of the clinching end stays. When the stays are pressed into the milled slot with the wire in place, the wire is locked in due to the cold flow of metal around it. The taut spring wire captivates a round follower with flanges above and below the wire runs. The follower is then free to move linearly and rotate in the panel. This follower is self-clinching and can attach a second sheet to the assembly by pressing a hole in the second sheet onto the follower.

International Classification:

F16B 15/08

US Classification:

411445

Abstract:

A fastener pin has a head at a topmost end that is the greatest diameter of the fastener. A shoulder extends downward from the head and includes a bottom surface for displacing material of a host object. A broaching section of rectangular lateral cross-section is located immediately below the displacer by cutting a rectangular profile into a round installation hole in the host object. Immediately below the broaching section is a tapered tip at a bottommost end which may be in the shape of a rectangular pyramid rotated radially out of alignment with the remainder of the other fastener features which all have parallel side edges. This individual fastener is one of a series of substantially identical pins attached toe-to-head at severable joints in a continuous string of fasteners.
