Description
- This application claims priority from U.S. Provisional Application Ser. No. 60/197,951 filed Apr. 17, 2000.
- 1. Field of the Invention
- This invention relates generally to tools for lifting and carrying elongated objects such as pipes and hoses.
- 2. Description of the Related Art
- In oil field operations, it is frequently necessary to manually lift and carry oil field pipe or frac pipe. Similarly, in firefighting operations, fire hoses must be lifted and carried by hand. Typically, such pipes and hoses must be handled under wet and slippery conditions, which are generally hazardous to the personnel involved. Additionally, such pipes and hoses are generally quite heavy and difficult to handle, even under dry conditions, which causes physical fatigue in the personnel involved.
- U.S. Pat. No. 5,361,658, issued to Murphy on Nov. 8, 1994, discloses a hand tool for guiding a rubber hose being wound on a reel. The Murphy tool comprises a helix depending from a T-shaped handle. The helix is adapted for receiving a hose such that the hose runs lengthwise along the axis of the helix. Although the Murphy tool appears to be capable of guiding a flexible rubber hose, rope, or cable onto a reel, the Murphy tool is not directed to lifting and carrying heavy, relatively stiff, elongated objects such as steel pipe or fire hoses.
- U.S. Pat. No. 5,024,476, issued to Massey on Jun. 18, 1991, discloses a tool for assisting in manually raising a heavy elongated article a small distance (e.g., a few inches) off a firm surface so that a lifting sling may be passed beneath the article. The Massey tool comprises a handle having a pair of co-acting, part-cylindrical jaw members that operate in a scissor-like manner for gripping the article to be raised, and a fulcrum projects from one of the jaw members on which the tool can be pivoted to raise the article a short distance off the surface. Although the Massey tool is directed to handling heavy elongated objects such as oil field pipe, the Massey tool involves mechanically moving parts, which makes it relatively complex and expensive to manufacture. Further, the Massey tool is not directed to be used for manually carrying such pipe.
- U.S. Pat. No. 5,791,704, issued to Thompson et al. on Aug. 11, 1998, discloses a tool for manipulating irrigation pipes. The Thompson et al. tool involves a pivotally mounted arcuate jaw with a handle secured thereto, and a second arcuate jaw fixedly mounted to the handle. A spring biases the jaw members into clamping engagement with an irrigation pipe. The Thompson et al. tool is directed primarily to turning, connecting, and disconnecting irrigation pipe without the operator having to bend over and grasp the pipe by hand. Like the Massey tool described above, the Thompson et al. tool involves moving parts, which makes it relatively complex and expensive to manufacture, and it is not directed to be used for manually carrying such pipe.
- Thus, a need exists for a simple tool with no moving parts that would allow personnel to easily grasp, lift, and carry pipes, hoses, and other heavy elongated objects, particularly under wet and slippery conditions. Such a tool would increase safety and decrease physical fatigue of pipe handling personnel. Such a tool would also be simple to use, inexpensive to manufacture, and maintenance-free.
- To overcome the disadvantages of the existing tools described above, a tool in accordance with the present invention comprises a simple rod having a series of curved segments and straight segments that form a cradle capable of grasping an elongated object such as a pipe or a hose. The curvilinear rod has a handle on one end that preferably comprises a foam rubber or other resilient material to facilitate grasping the tool under slippery or wet conditions.
- It is an object of the present invention to provide a simple tool with no moving parts for grasping, lifting, and carrying elongated objects such as pipes and hoses.
- It is a further object of the present invention to provide a tool for grasping, lifting, and carrying elongated objects under slippery and wet conditions.
- Further objects and advantages of the present invention will be readily apparent to those skilled in the art from the following detailed description taken in conjunction with the annexed sheets of drawings, which illustrate a preferred embodiment of the invention.
- FIG. 1 is a perspective view of a tool in accordance with the present invention.
- FIG. 2 is a perspective view of the tool of FIG. 1 being engaged with a section of pipe.
- FIG. 3 is a perspective view of the tool of FIG. 1 fully engaged with a section of pipe.
- FIG. 4 is a perspective view of an alternative tool in accordance with the present invention.
- FIG. 5 is a perspective view of another alternative tool in accordance with the present invention.
- Referring to FIG. 1, a
tool 10 in accordance with the present invention preferably comprises ahandle 12 depending from arod 13 having a series ofstraight segments curved segments tool 10, such an elongated object will lie generally alongaxis 32 and will be engaged withcurved segments rod 13 such that the elongated object may be lifted and carried by manually graspinghandle 12. Preferably,straight segment 16 is substantially perpendicular tostraight segment 14, andstraight segment 20 is substantially parallel tostraight segment 14. Preferably,curved segments straight segment 20.Curved segments curved segments rod 13, agusset 24 may be secured tosegments rod 13, and agusset 26 may be secured tosegments rod 13.Handle 12 may be integral torod 13, or handle 12 may be a separate piece fastened torod 13. - The use of
tool 10 in lifting apipe 30 is illustrated in FIGS. 2 and 3. As shown in FIG. 2, the process of engagingtool 10 withpipe 30 begins with placingpipe 30 betweencurved segments pipe 30 is oriented generally transverse tostraight segment 20 ofrod 13. To engagetool 10 onpipe 30,tool 10 is rotated by movinghandle 12 in the direction indicated byarrow 28 untilstraight segment 20 ofrod 13 andhandle 12 are generally parallel topipe 30 as shown in FIG. 3. In the fully engaged position shown in FIG. 3,curved segment 18 supports the lower portion ofpipe 30, andcurved segment 22 engages the upper portion ofpipe 30 such thatpipe 30 may be lifted and carried by manuallygrasping handle 12. - FIGS. 4 and 5 illustrate alternative handles for a tool in accordance with the present invention. Specifically, FIG. 4 shows a
tool 110 having ahandle 112 that is substantially perpendicular tosegment 114, and FIG. 5 shows a tool 210 having ahandle 212 attached tosegment 214 with aU-shaped bracket 215. Other suitable handles could also be incorporated into a tool embodying this invention so long as an appropriate series of straight segments and curved segments are provided for grasping an elongated object. - If
tool 10 is to be used for lifting and carrying oil field pipe or frac pipe,rod 13 is preferably made from ½-inch diameter steel, which may be heated and formed into the shape shown in FIG. 1.Rod 13 may also be manufactured by other processes, such as machining or casting, and materials other than steel may also be used.Rod 13 is preferably coated with a rubber or plastic material so thatsegments pipe 30, particularly whenpipe 30 is slippery from a liquid such as oil or water. Similarly, handle 12 preferably comprises a foam rubber material or other suitable resilient material that may be grasped more effectively under slippery or wet conditions such as those frequently encountered in the oil field or around fire hoses. Although the primary application of this invention is contemplated in connection with oil field pipe or fire hoses, this invention may be applied to advantage in any endeavor in which elongated objects must be moved. Additionally, although the present invention is intended primarily as a manual tool, it will be apparent to those skilled in the art that handle 12 may be replaced by a suitable fitting that would allowtool 10 to be attached to a machine that could be used to lift and move the desired elongated objects. - Although the foregoing specific details describe a preferred embodiment of this invention, persons reasonably skilled in the art will recognize that various changes may be made in the details of this invention without departing from the spirit and scope of the invention as defined in the appended claims Therefore, it should be understood that this invention is not to be limited to the specific details shown and described herein.
