Appl. No.:

13/581525

Inventors:

Marc R. Risdale - Ontario, CA
Robert A. Murawski - Clinton Township MI, US

Assignee:

ILLINOIS TOOL WORKS, INC. - Glenview IL

International Classification:

F16B 13/02
B29C 45/16

US Classification:

24458, 264255

Abstract:

A one piece snap-in retainer of multi-shot molded construction adapted to separate along a molded-in fracture line upon application of axial tensioning force. The retainer includes a base clip portion of molded polymer with a proximal barrel segment and a distal snap-in element projecting outwardly away from the barrel segment. The retainer also includes a head portion of molded polymer at least partially surrounding the proximal barrel segment. The molded-in fracture line includes a protuberance molded into the proximal barrel segment or the head portion at the interface in combination with an opposing complimentary mating depression molded into the other of the proximal barrel segment or the head portion.

International Classification:

F16B 5/06
B23P 19/08

US Classification:

411 78, 2952505, 411 80

Abstract:

A press-in fastener adapted to join a first component to a second component. The fastener includes a proximal head and a distal base clip portion below the head. The base clip portion includes an axially displaceable post structure and a pair of opposing wings extending in upwardly angled relation away from the travel path defined by the post structure. Collapsible legs engage the wings in operative connection to the post structure. As the fastener is pressed inwardly, upon encountering resistance from the second component, the legs collapse in folded relation as the post structure travels axially between the wings.

International Classification:

F16B 5/00
F16B 5/06
F16B 2/22
F16B 19/00
F16B 21/08

Abstract:

A press-in retainer is configured to join a surface element to a support structure that has an acceptance opening. The press-in retainer includes a retainer head including a collar, a platform, and a neck disposed between the collar and the platform. The retainer head is configured for placement into a channel defined by the surface element. A seal is disposed about a perimeter of the collar and includes a main body and a sealing foot. The sealing foot is connected to the main body by a living hinge extending along a perimeter of the main body and is disposed entirely outboard from the collar. A clip portion extends from the collar of the retainer head. The clip portion is configured for insertion into the acceptance opening of the support structure and includes two or more wing elements.

F16B 19/00
F16B 21/08

Abstract:

A press-in retainer includes a retainer head having a collar and a seal disposed at least partially about the collar. A clip portion projects from the collar. The seal includes a main body engaging the collar and a sealing foot disposed entirely outboard from the collar. The sealing foot is configured to hinge about an intersection of the sealing foot and body portion while remaining entirely outboard from the main body. In a substantially flattened condition of the sealing foot, an angle between the sealing foot and a distal surface of the main body approaches a flat contiguous surface.

Abstract:

A connection assembly adapted to join a surface element to an underlying support structure while maintaining a substantially zero gap abutting relation between the surface element and the support structure. The connection assembly includes a press-in retainer with a circumferential seal having a sealing foot. The sealing foot flexes about a living hinge while maintaining continuous sliding contact with the support panel without interfering with downward movement of the retainer.
