Filed:

Dec 7, 1999

Appl. No.:

09/457210

Inventors:

Daniel H. Walker - Sylvan Lake MI
Lyle D. Tincknell - Oxford MI

Assignee:

ITT Manufacturing Enterprises, Inc. - Wilmington DE

International Classification:

F16L 3500

US Classification:

285 39, 285321

Abstract:

A quick connector for connecting fluid lines includes a first connector having a housing for receiving a spool carrying conduit. The spool sealingly engages an endform on the conduit. At least one seal element and a retainer ring are pre-mounted in a bore in the housing and engage the spool to form a seal between the inner surface of the bore in the housing and the spool and to retain the spool in a fully inserted position in the housing. A method of assembling the quick connector is disclosed in which a stuffer pin is preassembled with the retainer ring mounted at a compressed diameter within a retaining collar on one end of the stuffer pin and the seal element mounted the stuffer pin. The stuffer pin is inserted into the bore in the housing until the seal element snaps into one groove in the bore and the retainer ring engages another groove in the bore in the housing. The stuffer pin is removed and a spool having a tapered end portion is slid through the retainer ring causing the tapered portion to expand the retaining ring outward until the retaining ring snaps behind an end shoulder on the spool. A centering collar carried on one of the spool engages an inner surface of the retaining ring to concentrically center the retaining ring with respect to a longitudinal axis through the tube and spool.

International Classification:

F16L 3900

US Classification:

285305, 285319

Abstract:

A connection between a fluid conduit and an air flow port mounted on an air flow device includes a housing having a through bore which receives a flange on an end form of the conduit. One end of the port is disposed in the bore in the housing in sealed engagement with the end form. A transverse bore in the housing receives a retainer to lock the port in the housing preventing axial separation of the port from the conduit.

US Classification:

2851201, 2851231, 2851251, 285305, 285319, 285921

Abstract:

A quick connect body having first, second and third ports carries an insert extending from the first port to the third port and forming first and second flow paths through the body from the first and second ports, respectively, to concentrically mounted conduits attached to the third port and to one end of the insert. Retainer elements are mounted on the body and/or the insert to sealingly couple first and second conduits to the body and the insert.

Inventors:

Daniel H. Walker - Sylvan Lake MI

Assignee:

ITT Manufacturing Enterprises, Inc. - Wilmington DE

International Classification:

F16L 3700

US Classification:

285305, 285308, 285 81

Abstract:

A quick connector includes a male component in the form of a spool fixedly mounted to a fluid conduit and a female component in the form of a housing having a bore open at one end for receiving the male component therein. A latch is rotatably mountable on the spool and is movable relative to a transverse channel in the female component between a first installed position with respect to the channel and a second latched position wherein the latch engages opposed notches in the channel to latch the spool in the housing. At least one latch clip is mountable on the latch and engageable with edges of the channel in the body to resist rotation of the latch from the latched position. An optional secondary latch clip is engageable with the latch clip, the latch and the opposed side edges of the channel to further resist rotation of the latch from the latched position.

International Classification:

H01R013/514

US Classification:

439/752000

Abstract:

An electrically conductive quick connector housing is matingly engagable with an electrically conductive male endform. An electrically conductive contact member is mounted in the bore of the housing and has an arm extending from a mounting portion which is engagable with the male endform when the male endform is inserted into the housing to electrically connect the male endform to the housing. The mounting portion is in the form of a tubular body or an annular ring. In the case of the annular ring, angular fingers project from the ring for engagement with the housing.

Inventors:

Randy Krause - Dryden MI, US
Daniel Walker - Sylvan Lake MI, US

International Classification:

F16L 37/00

US Classification:

285305000

Abstract:

A fluid quick connector couples an endform having a raised flange in a bore of a fluid operative element. In one aspect, a retainer in the form of a plate has opposed edges forming channels movably mounting the plate on a housing. Side tabs releasably lock the retainer in a moved position to latch the endform in the housing. In another aspect, the retainer includes spring arms which bias the retainer to the second position. The retainer is held in the first position by a lip of a top hat extending outward from the housing. The top hat moves longitudinally inward upon engagement with an endform to free the spring arms to automatically move the retainer to the second position latching the endform in the housing.

International Classification:

F16L 39/00

US Classification:

285319000

Abstract:

A fluid quick connector includes a housing and a sleeve movable between first and second positions within the housing upon engagement with an endform inserted into the housing. A retainer mounted on the housing includes at least one radially inward extending protrusion which extends through an aperture in the housing into engagement with the endform to latch the endform in the housing. The sleeve, when in the first position, blocks extension of the protrusion through the aperture in the housing to allow insertion of the endform in the housing. Movement of the sleeve to the second position allows the retainer to retract moving the protrusion through the aperture in the housing into engagement with the endform.

Abstract:

Disclosed is a device for the transport of temperature sensitive products including an insulated container, an insulated lid, a fastener to secure the lid to the container, an active heat exchanger, a thermal circuit to circulate heat exchange, a temperature sensor read by a temperature regulating circuit that maintains a temperature range, a power source, and a support frame that arranges the elements of the device with the overall center of mass at a location adapted for transport and storage of the device. Disclosed is also a method of transport for temperature sensitive products including securing the temperature sensitive product within an insulated container with a lid, removing heat from the container to maintain a temperature range, strapping the device onto the user's back and adjusting to the shape of the user, freeing both hands during transport of the device, and minimizing hindrances to user mobility caused by the device.
