20100140924 | APPARATUS FOR PROTECTING A SWIVEL ON A FIRE DEPARTMENT CONNECTION - A swivel protection device comprises an enclosure and a locking plug. The enclosure covers a portion of a swivel of a fire department connection that includes a set plug. The set plug holds the swivel onto the fire department connection. The enclosure covers the set plug such that, when the enclosure is locked over the swivel, access to the set plug is severely limited or excluded. | 06-10-2010 |
20110101674 | SYSTEM FOR THE LEAKTIGHT CONNECTION OF VALVE UNITS TO RESPECTIVE PIPES, IN PARTICULAR FOR USE WITH COMBUSTIBLE GASES - A system for the leaktight connection of a valve unit to a respective pipe, is provided. The valve unit includes a gas through-flow section, a threaded male attachment element being formed integrally with the valve unit and having an axial through cavity defining the gas through-flow section, for leaktight clamping by a pipe-fixing ring-nut connector which can be screwed onto the male threaded portion of the attachment element. The system includes a second leaktight connector which can be put into operation as an alternative to the ring-nut connector. The second connector including at least one axial retaining element which can be releasably restrained on the valve unit in the region of the threaded portion of the male attachment element, in a manner such that the pipe is restrained axially relative to the valve unit. | 05-05-2011 |

20140035273 | FLUID LINE SAFETY DEVICE - A restraining device for a tubing connector assembly can include a resilient member having a generally U-shape with forked ends that curve toward each other. Each forked end can have a recess between tines thereof. Each recess can have a blind end. The resilient member can have a bend provided with an engagement bump. The engagement bump and forked ends can be aligned such that the engagement bump coincides with a line joining the blind ends. When a cylindrical connector assembly tube is placed in the recesses, the engagement bump is urged against a side of the connector assembly to thereby prevent inadvertent disconnection. | 02-06-2014 |
20140284918 | Coupling Nut Assembly - A coupling assembly for coupling annular fittings includes first and second coupling elements. The first coupling element defines interior and exterior opposite surfaces, and first and second end opposite portions. The first coupling element includes a plurality of flexible tabs slantedly protruding from the exterior surface; and also includes threads configured along the interior surface at the first end portion. The second end portion is non-threaded. The second coupling element defines inner and outer opposite surfaces. The second coupling element includes a plurality of rigid tabs vertically protruding from the inner surface. The second coupling element coaxially engages the first coupling element such that the flexible tabs and rigid tabs interact with each other to tighten and loosen the coupling assembly against the annular fittings via torque application. While tightening, the non-threaded second end portion and the flexible tabs and rigid tabs combination preclude over-tightening. | 09-25-2014 |
20140312611 | LOCKING FLUID FITTINGS - A fluid conduit for a gas turbine engine includes a first fluid conduit attachable to a second fluid conduit and securable together with a lockable connector. The connector includes a first portion including external threads and a second portion receiving the first portion and including internal threads mating to the external threads of the first portion. The internal threads include lead threads defining a first thread interface with the external threads for starting attachment of the first portion to the second portion and locking threads defining a second thread interface for locking the first portion to the second portion. | 10-23-2014 |
20140339811 | Mechanical Friction Enhancement for Threaded Connection Incorporating Crushable Ribs - A medical connector includes a body having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end, a helical thread extending radially outward from a surface of the sidewall and comprising a crest portion, flank portions, and a root portion with the flank portions connecting the crest portion to the root portion, and at least one deformable protrusion extending radially outward from the root portion of the helical thread. | 11-20-2014 |
20140339812 | Mechanical Friction Enhancement for Threaded Connection Incorporating Micro-Threads - A medical connector includes a body having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end, a helical thread extending radially outward from a surface of the sidewall and comprising a crest portion, flank portions, and a root portion with the flank portions connecting the root portion to the crest portion, and at least one micro-thread extending radially outward from the surface of the sidewall. At least a portion of the micro-thread is spaced apart from the helical thread. | 11-20-2014 |
20140339813 | Mechanical Friction Enhancement for Threaded Connection Incorporating Opposing Barb - A medical connector includes a body having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end. The medical connector further includes a helical thread extending radially outward from a surface of the sidewall and at least one protrusion extending radially outward from a surface of the sidewall. The at least one protrusion has a first side and a second side. A radial height of the at least one protrusion from the surface of the sidewall tapers circumferentially from the first side of the at least one protrusion to the second side of the at least one protrusion. | 11-20-2014 |
20150297453 | Syringe Adapter with Compound Motion Disengagement - An adapter for connection with a fluid container includes an outer housing having a distal end, a proximal end, and a generally cylindrical sidewall extending between the distal end and the proximal end, an inner member comprising a body rotatably inserted within the outer housing, a first locking arrangement configured to restrict the inner member from rotating relative to the housing in a first direction, and a second locking arrangement configured to restrict the inner member from rotating relative to the housing in both the first direction and a second direction. The adapter is transitionable between: a disengaged state, in which the first locking arrangement and the second locking arrangement are not engaged with the inner member; a partially engaged state in which the first locking arrangement engages the inner member; and a fully engaged state in which the second locking arrangement engages the inner member. | 10-22-2015 |
20150308591 | SECURITY ADAPTER - A security adapter, which is provided for connecting a first and a second fluid line portion of a fluid line. The security adapter has an inner sleeve, which at a first sleeve end region has a fastening thread provided for connection to a first fluid line portion and at a second sleeve end region has an outer thread in the form of a movement thread. The outer thread can be screwed together with an inner thread of an outer sleeve, wherein the sleeve inner circumference of the outer sleeve is provided with a stop, against which a counter stop arranged on the outer circumference of the inner sleeve bears, in a rotational end position of the security adapter such that the inner sleeve and the outer sleeve are freely rotatable in relation to one another without engagement of the inner and outer thread forming the movement thread. In a screwed-in end position, the inner sleeve is screwed by way of its outer thread into the inner thread of the outer sleeve such that a stop surface on the inner sleeve bears against a counter stop surface on the outer sleeve. | 10-29-2015 |
