    A TOOL FOR ATTACHING AND REMOVING FITTINGSto ' CA 02360297 2001-10-26 This application is a continuation -in-part of pending applicati on Serial Number 091563,180, filed May 2, 2000, the teachings of which are in -corporated herein by refierence. FIELD OF THE INVENTIONThis invention relates to a tool for removing and attaching fittings which are used to attach hoses, such as fittings used on hydraulic hoses. Hydraulic hoses are mounted to hydraulic devices or to other hydraulic hoses by means of hydraulic fittings which connect the hoses to the hydraulic device or other hose. Fittings are commonly mounted to the end of the hose and have threaded means for attaching the hose to threads mounted on the device to which the hose is attached, or to the fitting of another hose. The threaded fitting typically has means for rotating a part of the fitting to secure the threads. The fitting may 2o comprise a six-point fastener with accepts an open end wrench of the appropriate size and of the type commonly in use. Fittings typically have a swivel means, which allows the hose to rotate or pivot relative to the fitting and the device to which the device is attached.Fittings as described, such as hydraulic fittings, may be attached by means of the threads to another threaded fitting which will accept threads. In the prior art, open end wrenches are commonly used to advance and secure the threads, and to remove fittings. The problems with using hand wrenches of this type is two fold:(1 ) Rotation of the wrench is relatively slow when compared with other tools, such as ratchets; and (2) the position of the fitting relative to other parts of the machine to 3o which the hose is attached is commonly such that access to the fitting is limited, meaning that the hand wrench either cannot be used, or rotation of the threads by means of the hand wrench is limited to a few degrees. The use of a ratchet or impact wrench expedites the attachment and removal of various threaded fasteners. Devices known as sockets, which are usually of six point (hexagonal) or twelve point design, are attached to the ratchet or impact wrench, and the socket is rotated to secure the fastener or remove the fastener.Heretofore, no socket has been available for wrenches or impact wrenches which will allow the removal of a threaded fitting which is attached to a hose.1 o SUMMARY OF THE PRESENT INVENT10NThe present invention provides a tool for attaching or removing fittings which are commonly used in conjunction with hoses, such as fittings attached to hydraulic hoses. The device has a removable adaptor with a hex shaped interior which engages the hose fitting, while the opposite end has a drive hole, which is typically ~ 5 rectangular, to accept the square drive of commonly used tools, such as ratchets, torque wrenches or impact wrenches. Interchangeable adaptors having hex shaped interiors of varying sizes the device to be used on multiple sizes of fittings. An adaptor is mounted to the end of the body . The adaptor is removable.The adaptor engages the fitting, and is sized according to the fitting. The adaptor is 2o mounted to the body by male female engagement. DESCRIPTION OF THE DRAWINGS Figure 1 is an exploded view of the device. Figures 2 and 3 are side elevations of device.25 Figure 4 is an elevation showing the end of the tool having an adaptor fitted thereto.
    Figure 5 is an elevation showing the end of the tool which is opposite Figure 4, showing the drive hole. Figure 6 is a side elevation of the device shown as a phantom, with the hose having a fitting thereon positioned within the tool, for use with the tool. DESCRIPTION OF THE PREFERRED EMBODIMENTReferring now to the drawing figures, Figure 2 shows the fitting tool having a longitudinal and hollow body 2. The body is open along a substantial portion of the ~ 0 length of the body to receive the hose 4 to which the fitting 8 is attached. An adaptor 5 is fitted to an end of the body. One end of the body is formed to receive the adaptor. The adaptor has an opening 6 for receiving the fastener which is attached to the hose. The exact size of the opening will depend on the particular size of the fastener which is present on the hydraulic hose to be attached ~ 5 or removed. The opening in the adaptor may be shaped to receive six point or twelve point fasteners, or the opening may otherwise be shaped accordingly to the required application. In the preferred embodiment, the hex shaped opening in the adaptor is actually four sided, with the remaining two sides of the. hexagonal shape eliminated.2o Figure 4. This shape allows the device to accept the fastener of the fitting which is attached to the hose, and firmly grasp the fastener for rotation of the fastener. On the end of the body opposite the hex shaped end, a drive hole 12 is provided.Figure 5. This drive hole is sized appropriately for the drive tool, and will most commonly be rectangular according to the drives of ratchets, torque wrenches and 2s impact wrenches in common use. By way of example, the drive hole could be one-quarter inch, three-eighths inch, or one-half inch, or larger, as is appropriate to the fitting, the job and the drive tool to be used. The longitudinal opening 14 of the body ! CA 02360297 2001-10-26 is preferred to not extend to the end in which the drive hole is located, so that increased structural integrity is provided in close proximity of the drive hole. Since the application of torque to the device occurs at the drive hole, the structural integrity of the device at this position is important. In the preferred embodiment, the device also provides an external hexagonal shaped drive 16. As shown, this hex shaped drive has four sides and is open as part of the opening to the longitudinal body. This external hexagonal drive receives an open end wrench and allows an open end wrench to be used to rotate the device. An open end wrench of the appropriate size is attached to the device and is ~ o rotated to rotate the device.A portion of the external surface 18 may be knurled to accommodate handling and manual rotation of the device. A peg board hole t0 may be provided. As is demonstrated by Figure 4, the slotted opening of the hollow, longitudinal body, gives the device a u-shape when viewed from the end. In use, the ~s hex opening is mated with the six point fastener 20 of the fitting. The remainder of the fitting, and the end of the hose to which the fitting is attached, extend into the hollow body, and out of the slotted opening. Accordingly, the slotted opening facilitates the engagement of the hex end and accommodates the hose. When attaching a fitting, the device may be initially rotated by hand for the 2o purpose of engagement of the fitting. Additional torque may be supplied by means of a drive tool fitted to the drive hole. Alternatively, or additionally if increased torque is desired, the hand wrench may be fitted to the external hex. The device is now used to apply torque to the fastener to attach the hose. The hose and fitting are removed in a similar manner by rotating the device in the opposite direction. A drive tool may 25 be fitted to the device by means of the drive hole, and if additional torque is required to loosen the fitting, a hand wrench may be applied to the exterior hexagonal shaped portion of the body.
    Adaptors having openings of various sizes may be provided. The openings are matched to the fitting or fastener to be attached or removed, and the adaptor selected accordingly. Adaptors having openings of various sizes may be fitted to a single body, since the adaptors are uniform as structured to be received by and engage the body. As shown in Figure 1, the end of the body of the device, which receives and engages the adaptor, has three pins 22, 24, 26. These pins engage corresponding voids. For example, pin 22 engages void 28. Similar corresponding voids are provided for pins 24 and 26. The pins and voids hold the adaptor in place on the body, and receive a torque transfer from the body to the adaptor, which is in tum transferred to the fitting to be attached or removed.Each pin may be provided with a resilient portion 30 to frictionalty engage the void and aid in retaining the adaptor on the body. The resilient portion may be an o-ring formed of rubber, neoprene, plastic or similar materials.1 s The pins engage in a male-female relationship with a corresponding void on the other part. One or more of the pins, or all three of the pins, could extend from the adaptor to corresponding voids located in the body.
