    The invention relates to a quick connect connection for connecting a first part to a second part, and in an exemplary application the invention relates to a quick connect connection for connecting a water hose to a water blaster.
    In the irrigation industry many different "quick connections" are used. These connections allow the user to irrigate large areas with fewer water sprinklers and to remove the water sprinklers when not in use. Problems arise with portable water sprinklers. The first is security, where many of the current connectors can not be properly connected and / or disconnected. This can be dangerous to the user who moves these water sprinklers because if he opens the valve and pressurizes the system, the water sprinkler may be thrown into the air due to the fact that the connection is not properly engaged. Many can also be opened under pressure and can throw the water blaster into the air. Existing quick connectors include, for example, cam lock, ring lock, Certa set and ball joint connectors.
    The cam lock connector uses two self-locking and over centers, respectively
    Cams turning into a groove cut in the connector side of the connection. These cams tighten the connection and exert a positive pressure on the gasket that sits inside the receptacle connector. There are some potential pitfalls when using this cam lock system. If both cams are not fully turned down, there is a possibility that the connection will be torn apart and possibly injure the user. The cams can also be released under water / fluid pressure, which is dangerous because if the water sprinkler is plugged in and the waterer releases the cams this can cause the water sprinkler to be released and thrown into the air.
    The ring lock connector uses male and female connectors which are connected to a "ring" which holds the two together. These rings have either a self-locking cam lock or a bolt connection. The self-locking cam is more of a viable solution to allow for quick assembly and disassembly. However, the self-locking cam ring lock can be opened while under water / fluid pressure, which can cause the connection to be disconnected and the
    2.22
    User injured. It can also be locked while the tube is misaligned, which can cause the connection to fail and become disconnected.
    The Certa set connector uses a male and female connection held together by a plastic serration which is inserted into a slot, thereby holding the connection together. This connection can also be opened under water / fluid pressure, and if the user forgets to install the plastic spline, the connection can be disconnected while under pressure and throw the water blaster into the air.
    The ball joint connector uses a male and female connection which is held together with two clamps which contract the connection. If the latches on the lip of the socket are not properly hooked, this connection can be released when the system is pressurized.
    BRIEF OVERVIEW It would be desirable to provide a quick connect fitting suitable for a

    DETAILED DESCRIPTION Referring to the drawings, quick connect fitting 10 according to the described environments is shown in an exemplary application for an irrigation system, wherein the quick connect fitting connects a water hose in which water flows under pressure to a water blaster. The application shown is exemplary, and the
    Quick connect connection may be applicable to other applications, as will be apparent to one of ordinary skill in the art. The invention should not necessarily be limited to the application shown.
    The quick connect terminal 10 has a base 12 attachable to a first part and a connection plate or plate assembly 14 attachable to a second part. As indicated, in the exemplary application shown, the first part may be a water hose in which water flows under pressure and the second part may be a water blaster. The base 12 has an engagement surface 16 with a surface 16 in the intervention defined T-bolt slot 18. As shown, the T-bolt slot 18 in an edge region of the engaging surface 16 is defined. The base 12 also has a tab opening 20 which is defined by a bracket 22 which extends from the engagement surface 16. The bracket 22, which defines the tab opening 20, may be integral with the base 12.
    The connecting plate 14 is provided with a tab member 24 which is of the
    Connecting plate 14 protrudes. The tab member 24 is sized and shaped to fit in the tab opening 20 of the base 12. The tab element 24 can thus be brought into engagement with the clip 22 in the tab opening 20 of the base 12. As shown in FIG. 3, the tab member 24 may be provided with a groove 25 on an upper surface. The groove 25 is engageable with the bracket 22 to hold the connection plate 14 in place if pressure is applied to the connection plate 14 (e.g., by opening a valve) before the connection plate is locked.
    Any suitable construction may be used to attach / receive the tab member 24 in assembling the quick connect connection. An exemplary alternative is shown in FIG. 4. This configuration works the same way as described above with the self-locking latch. From the top tie plate, the 5.08 cm (2 inch) NPT (standard pipe thread, US) joint has been removed, and it has a geometry that allows a direct bolt connection 50 with a water blaster, such as the Nelson Big Gun ™. This shortens the overall assembly, and as the bolts are hidden in the connection plate, this allows a water blaster, such as Nelson Big Gun ™, to be placed in areas where there may be problems with theft.
    A cam lock 26 extends through the connection plate 14. As shown, the cam lock 26 and the bracket 22 are positioned on opposite sides of the connection plate 14. The cam lock 26 has a cam actuator or handle 28 on one side of the link plate 14 connected to a T-bolt 30 and a T-bolt shaft 32 on an opposite side of the link plate 14. The cam actuator 28 is
    7/22 between a release position in which the T-bar 30 is located at the bottom, and a locking position in which the T-bolt 30 is raised to an engaged position, displaceable. The connecting plate 14 may be provided with a sealing member 34, such as a double lip ring seal, which provides a quality seal under different conditions. Two plates 36 or pads may be mounted on the engagement surface 16 of the base plate 12. The plates 36 are raised above the engagement surface 16 to allow dirt and small foreign matter to be present without impeding the sealing between the base 12 and the connection plate 14.
    The base 12 may be provided with a base socket 38 with internal thread for connection to the first part. Similarly, the connection plate 14 may be provided with an internally threaded connection plate socket 40 for connection to the second part. As shown in FIG. 1, the base 12 may also be provided with a cylindrical insert 42 protruding from the engagement surface 16 of the base. The connection plate 14 has an insertion opening 44 dimensioned to receive the insertion member 42. The insertion member 42 engages the insertion opening 44 when the connection plate 14 is engaged with the base 12. The insertion member 42 and the Einfiühröffhung 44 can be exchanged between the connecting plate 14 and the base 12.
    Referring to FIG. 3, the cam actuator / handle 28 is connected to a cam member 46 that rotates with the handle 28. A cam insert 48 is positioned between the cam member 46 and the connecting plate 14 and engaged with the cam member 46. The cam member 46 and the cam insert 48 are formed together so that rotation of the cam member 46 by the handle 28 or the like with respect to the cam insert 48 pulls the bolt shank 32 and the T-bolt 30 toward the cam member 46.
    The cam actuator 28 is thus about an axis through the cam member 46 in
    Generally rotatable parallel to a plane of the connecting plate 14. Cam actuator / handle 28 is also rotatable about a vertical axis through link plate 14 and base 12 in alignment with T-bar shaft 32. The cam actuator 28 is thus between an insertion position in which the T-bolt 30 is aligned with a longitudinal axis of the T-bolt slot 18 (FIG. 1), and a connection position in which the T-bolt 30 is not aligned with the longitudinal axis of the T-bar slot 18 is aligned, rotatable.
    In order to fix the quick connector 10, the tab 24 of FIG
    Connecting plate 14 inserted into the tab opening 20 of the base 12. With the cam lock 26 in the release position, in which the T-bolt 30 is aligned with the longitudinal axis of the T-bolt slot 18, the connecting plate 14 is pivoted into engagement with the base 12 and the TRiegel shaft 32 is inserted into the T-bolt. Latch slot 18 introduced. Thereafter, the cam actuator 28 can be rotated from the release position to the connecting position, in which the T-bolt 30 is not aligned with the longitudinal axis of the T-bolt slot 18. The cam lock 26 may then be self-lockingly displaced from the released position to a locking position via the actuator 28 to thereby pull the T-bolt 30 into engagement with the base 12.
    The tab 24 on the back of the connection plate 14 facilitates alignment of the quick connect connection. The user pushes the tab 24 only into the opening 20 in the base 12 until it stops, and the connection plate 14 is then pivoted down onto the base 12. The tab 24 also functions as an initial security feature in joining. The groove 25 cut in the top of the tab member 24 serves to prevent the connected part (e.g., the water sprinkler) and the connecting plate 14 from being thrown if a valve is opened without properly connecting the T-bolt 30. The groove 25 in the tab member 24 would rather engage the bracket 22 to catch the part and prevent it from flying away. This would give the user enough time to grab the water sprinkler and close the valve. The self-locking cam lock 26, the T-bar 30 and the TRiegel shaft 32 provide an additional safety feature. If the cam latch 26 is unlocked while the water blaster is under pressure or the like, then the link plate 14 will ride up until the T-bolt link engages. In the exemplary application, water leakage will result, but the structure would prevent the part from dislodging from the base 12. The T-bolt can also hold the connection together when the user forgets to latch the cam latch. Because the cam latch and tab are on opposite sides of the link plate, the assembly creates a connection that is difficult to disconnect under pressure, thereby providing additional protection for the user.
    FIGS. 5-7 show an alternative embodiment. This embodiment uses many of the same structural components for a secure and reliable connection. The quick connect port 110 has one in this embodiment
    22.9
    Locking mechanism 112 which uses a single self-locking cam 114 (see FIG. 7) which rotates with a lever 118 and engages a semicircular cam groove 116. The lever 118 is attached to the base and pivotally mounted between a pair of plates 124 via a pivot pin 119. The single cam 114 helps reduce the time required to connect the water sprinklers to the base. The lever 118 also has a locking hole 120 to allow a pin or bolt to be mounted in through holes 122 in the connection plate. That is, in the lock position, the lock hole 120 in the lever 118 is aligned with the through holes 122 in the plate pair 124. This allows the user to ensure that the water blaster is much more difficult to steal, or that no accidental opening of the connection due to the rubbing of animals on the riser.
    FIG. 5 shows the lever 118 in the depressed position, so that the
    Connection plate could be removed from the base, and the cam 114 is not engaged with the semicircular groove 116 in engagement. FIG. 6 shows the lever 118 turned upwards and the cam 114 engaged with the groove 116.
    With continued reference to FIGS. 5 and 6, a revised bracket is provided
    126 posts 128 and a crossbar 130 to define the pocket opening. The crossbar 130 is secured to the posts 128 with suitable connectors 132. The revised clamp 126 allows for better manufacturability. As shown in FIG. 7, a seal 134 may be positioned between the base and the connection plate.
    Although the invention has been described in conjunction with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary is intended to be various Modifications and equivalent arrangements included within the spirit and scope of the appended claims.
