20090001718 | Hydraulic Connector and a Hydraulic Circuit Incorporating the Connector - A hydraulic connector made entirely of an elastomeric material connects tubes or other hydraulic circuit components used in machines for extracorporeal blood treatment. The hydraulic connector comprises a main body ( | 01-01-2009 |
20090302600 | METAL COUPLING WITH LOCKED POSITION - A coupling comprising a body and a sleeve mounted coaxially on the body, the body defining a housing opening out in a face of the body to enable an end portion of the duct to be inserted therein, wherein the sleeve has an end projecting from said face of the body and provided with a catch step for catching the duct, wherein the sleeve is deformable radially and elastically from an endpiece-retaining state towards an endpiece-passing state, wherein the sleeve is mounted on the body to slide between first and second positions that are in successive relative to an insertion direction for inserting the duct into the housing, and wherein the body and the sleeve include complementary portions in relief that co-operate together when the sleeve is in its first position to hold the sleeve in its retaining state, and that are disengaged from each another when the sleeve is in its second position. | 12-10-2009 |
20110140414 | PTC Fitting Cartridge - A Push To Connect (PTC) fitting cartridge for connecting to a pneumatic device, such as, an air brake or a height control valve, the PTC fitting cartridge including at least one protrusion positioned on an outer surface of the PTC fitting cartridge, which is provided to interact with an undercut positioned on an inner surface of a port. The undercut interacts with the protrusion to substantially eliminate stress on the surrounding material to reduce the chance of fraction thereof. | 06-16-2011 |
20120068456 | REMOVABLE PUSH ELECTRICAL FITTING FOR ELECTRICAL METALLIC TUBING OR EMT HAVING IMPROVED PULLOUT RESISTANCE - An electrical fitting having a gripping device with a plurality of gripping tabs forming a helix or spiral. The gripping tabs have a twist creating increased pullout resistance and easier disassembly. The electrical fitting permits electrical metallic tubing or EMT to be quickly attached to and removed from the electrical fitting without disassembling the fitting or cutting the tubing. A body with a locking end having a plurality of griping tabs receives an end of the tubing pushed into the fitting. The gripping tabs securely hold the tubing preventing loosening or removal. The helix or spiral and twist formation of the griping tabs permits easy removal of the tubing by rotating the tubing counter-clockwise. | 03-22-2012 |
20120228871 | QUICK CONNECTION COUPLING - A coupling, conduit assembly, method for coupling conduits and faucet assembly are described herein, wherein the coupling includes a female section with a conduit connecting end and a retainer with at least one projection; a male section with a conduit connecting end and a male projecting portion with a two large diameter sections, each having an inwardly facing surface wherein the surfaces define a channel that is configured so a mating surface on the projection or projections contacts the surface of the first large diameter section when the coupling is locked; and a locking piece on the female section capable of sliding along that section to engage the projection or projections when situated in the channel so the mating surface on the projection or projections contacts the surface of the first large diameter section and the locking piece retains the projection or projections in position and locks the coupling. | 09-13-2012 |
20130207385 | PUSH TO CONNECT CONDUIT FITTING WITH FERRULE - A push to connect fitting includes a body member adapted to receive a conduit end, a conduit comprising a first end that can be axially inserted into the body member and a conduit gripping device attached to an exterior surface of the conduit, and a retainer that retains the conduit in place when said conduit is fully inserted into the body member. Additional embodiments include providing a seal with the fitting that seals the exterior surface of the conduit, an optional load retaining sleeve for the conduit gripping device, and an optional gimbal. The push to connect aspect may be realized in the form of a single action unthreaded mechanical connection. | 08-15-2013 |
20150330548 | APPARATUSES AND METHODS FOR PROVIDING QUICK-CONNECTIONS WITH RETAINING FEATURES - Fittings and coupling assemblies for relatively easy and quick connections to conduits are disclosed herein. A fitting assembly configured in accordance with an embodiment of the disclosure includes a male connector and a female connector that can be coupled together to form a fitting assembly for attachment to a conduit or tube. The male connector can include a retaining feature, such as an undulated barb, to correspond with a corresponding engagement feature, such as a tooth carried by a shroud of the female connector, to allow the male and female connectors to be rapidly coupled together and also prevent the connectors from unintentional loosening. To couple and also separate the male and female connectors, a user can apply a compressive force to at least one of the male and female connectors, followed by a partial rotation of one of the connectors. | 11-19-2015 |
