  • Patent number: 11371635
    Abstract: To provide a connector that facilitates assembly while having a great axial-direction engagement force, a male joint member to be connected to a first member has a plurality of outer protrusions, and a female joint member to be connected to a second member has a plurality of inner protrusions. A circumferential-direction gap between adjacent two inner protrusions allows the outer protrusion to pass therethrough. The female joint member has, in an area opposed to inner protrusion back surfaces, a circular space that allows the plurality of outer protrusions to relatively rotate therein. The inner protrusion back surfaces of the plurality of inner protrusions are engaged in the axial direction with outer protrusion back surfaces of the plurality of outer protrusions that have passed through the circumferential-direction gaps between the plurality of inner protrusions.

  • Patent number: 9080705
    Abstract: When releasing a connection between a second tube member and a first tube member, a ring member is moved, whereby an inclined surface of a bump part and an inclined surface of a bump part of a cam part slide, and a stopper rotates from a coupled position to an uncoupled position. Thus, a coupling between a leading end part of a claw part of the stopper on the second tube member, and a coupling surface of a coupling-accepting part on the first tube member is released. In connecting the first and second tube members, when the first tube member is pushed into the second tube member with the ring member in the locked position, the claw part of the stopper is elastically deformed, whereby the leading end part of the claw part rides past the coupling-accepting part, and couples to the coupling surface of the coupling-accepting part.

    Abstract: A spray shield for the pipe connection flange of pipes carrying hazardous fluids. A band composed of metal or other suitable material encompasses a pipe flange and supports a spray diffusion mesh or device so that any spray of pressurized leaked fluid is coalesced to drops or streams of leaked fluid which descend by gravity for collection rather than being sprayed into the environment in the vicinity of the leaking flange joint. The spray shield band is secured about the flange by an over-center latch mechanism that tightens the band and spray diffusion mesh around the flange connection. A locking pin or lockout device is inserted through aligned holes of the latch mechanism when closed and functions to secure the latch against release and movement from its latched position.

    Abstract: A split ring assembly for maintaining a releasable pipe coupling, of the type having a female portion having two pivoted opposite cam lever arms and a circumferentially grooved male portion, in an engaged position comprising: two generally semicircular ring portions hinged together on one side and provided with a latch mechanism on a diametrically opposite side; wherein each ring portion is notched to receive a swinging end portion of one of the cam lever arms; and wherein each ring portion is sized to closely surround the female portion of the pipe coupling. Then when the ring assembly surrounds said female portion and the pivoted arms, closing the latch mechanism visibly ensures that the coupling portions remain locked together. The split ring assembly is a rugged visibly convincing assurance that a coupling will not inopportunely open. It can be manipulated by an operator wearing heavy gloves in subzero weather or during a snow storm.

  • Publication number: 20090008930
    Abstract: There is provided a pipe fitting in which loss of a sleeve is prevented, and the sealing performance of a joint portion is ensured while enhancing the workability at the time of connecting pipes. Also, a refrigerating apparatus and the like using the pipe fitting are provided. A sleeve (15) is provided integrally with a nut (14) before joining of a pipe, and cut off and separated from the nut (14) by screwing of the nut (14) into a fitting body. Moreover, an inner circumferential surface (15d) of the sleeve (15) is formed with a recess portion (15g). Thus, when the sleeve (15) bites into a pipe (12), deformation of a contact surface (15c) is induced so that a contact area A1 of a contact portion between the contact surface (15c) and a guide surface (13d) is increased by a pressing force from an inner surface (14c) of the nut (14).

  • Patent number: 6629707
    Abstract: A pipe jointing unit includes a cylindrical joint in which is accommodated a pipe, a ring-shaped seal member positioned in the joint, an elastic connecting member positioned in the joint and holding the pipe and the ring-shaped seal member in the joint, and a guide member detachably connected to the joint. The guide has an annular guide portion which is disposed circumferentially between the inner surface of the edge portion of the joint and the outer surface of the pipe. The pipe is thus restricted from swinging in the radial direction relatively against the joint and the reliability of the resistance force against pulling the pipe out of the connecting member by vehicle vibration, an increase of the internal pressure of the pipe and the like is improved.

  • Patent number: 6543812
    Abstract: A self-locking quick release coupler includes a handle and a lever. The first distal end of the handle is adapted to be secured to a side face of the groove adapter. The handle has a head formed on the first distal end thereof. The head is extendable into a side face of the groove adapter so as to secure a tube inserted into the groove adapter. The lever partially extends through the handle to be pivotably received in the handle. The lever has a hook formed on a first distal end of the lever to adapt to hook a pin of the groove adapter and a press formed on a second distal end of the lever. The pivotable movement of the lever allows the hook of the lever to selectively hook the pin so as to secure the handle relative to the groove adapter.

    Abstract: A tube connecting device comprises a housing, a socket formed in the housing for receipt of a pipe to be releasably secured therein and a securing arm pivotally mounted to the housing. The securing arm is pivotable from a first, locked position in which a portion of the arm projects through an associated aperture in the wall of the socket to engage a complementarily-shaped portion of the pipe to be retained, to a second unlocked position in which the projecting portion of the securing arm is withdrawn from the socket. The device further comprises an actuator mounted on the arm and a locking member located in a chamber within the arm.

  • Patent number: 6206433
    Abstract: A coupling is disclosed for connecting conduits that carry combustion air to an internal combustion engine. Two conduits are provide, a first one having an associated locking collar with slots and flexible locking fingers, and a second one having several outwardly facing pins and catches located on an outer surface. The pins are received in the slots and the two conduits are rotated with respect to each other. The catches and locking fingers engage to prevent the two conduits from being pulled apart. Both conduits and locking collar are preferably made of plastic, with the second one and its associated locking collar being simltaneously and integrally molded. A resilient seal may be located between the two components to reduce or eliminate air leakage.

  • Patent number: 5943461
    Abstract: An optical module is packaged using one or more internal fiber connections which are arranged to minimize the likelihood of internal connection damage when the module is installed on a circuit board. The module includes at least one external connector arranged on a side of the package, and a submount within the package for supporting a component such as an optical source or an optical detector. An optical fiber is connected within the package from the submount to a connector interface of the external connector. The end of the fiber at the connector interface has a preformed connector thereon which engages a ferrule associated with the interface. The other end of the fiber is attached to the submount for optimal coupling efficiency. The fiber may undergo a bend of about 90.degree. or 180.degree. from its first end to its second end. In order to accommodate the fiber bend, the component submount is positioned within the package in a location remote from the external connector.
