Description
- 1. Field of the Invention
- The invention relates to a hydraulic tool and, more particularly, to a hydraulic tool having more than one handle.
- 2. Brief Description of Prior Developments
- Electric powered rotary tools, such as drills, sanders and grinders, are known which include two handles for a user, such as shown in U.S. patent application publication Nos. 2006/0075851A1 and 2005/0249564 for example. U.S. Pat. No. 5,282,378 also discloses a hydraulic tool with two handles.
- Battery operated hydraulic crimping and cutting tools are also well known in the art, such as described in U.S. Pat. No. 6,745,611 B2 for example, which is hereby incorporated by reference in its entirety. These battery operated hydraulic crimping and cutting tools are traditionally designed to be held with one hand and, thus, have a single handle. As electrical industry demands drive up the use of larger conductor sizes, tools will be produced to install the required larger size connectors. The working heads of these tools are inevitably going to get larger and heavier in order to crimp larger size connectors. This will make a single handle battery operated hydraulic tool disproportionately heavy at its front end (nose-heavy) and somewhat uncomfortable to hold with a single hand during use.
- There is a desire to provide a battery operated, hydraulic crimping tool which can be held with two hands to allow for more comfortable use when the tool has a heavy working head.
- In accordance with one aspect of the invention, a hydraulic tool is provided including a main section and a working head. The main section has a hydraulic drive system including a pump and a hydraulic fluid conduit system, and a first handle adapted to allow a user to grasp the main section with a first hand. The working head is connected to the main section and includes a frame, a ram movably connected to the frame, and a second handle extending from the frame. The ram is adapted to be moved on the frame by hydraulic fluid from the hydraulic drive system. The second handle is adapted to allow a user to grasp the working head with a second hand away from a compression area between the ram and an opposite anvil section of the frame.
- In accordance with another aspect of the invention, a hydraulic tool is provided comprising a main section and a working head. The main section has a hydraulic drive system comprising a pump and a hydraulic fluid conduit system, and a first handle adapted to allow a user to grasp the main section with a first hand. The working head is connected to the main section and comprises a frame, a ram movably connected to the frame, and a second handle movably connected to the frame. The ram is adapted to be moved on the frame by hydraulic fluid from the hydraulic drive system. The second handle is movably relative to the frame between a first position and a second position. In the first position the second handle is adapted to allow a user to grasp the working head with a second hand away from a compression area between the ram and an opposite anvil section of the frame. In the second position the second handle is in a different storage position in the frame.
- In accordance with another aspect of the invention, a hydraulic tool is provided comprising a main section and a working head. The main section has a hydraulic drive system comprising a pump and a hydraulic fluid conduit system, and a first handle adapted to allow a user to grasp the main section with a first hand. The working head is connected to the main section and comprises a frame, a ram movably connected to the frame, and a second handle repositionably connected to the frame. The ram is adapted to be moved on the frame by hydraulic fluid from the hydraulic drive system. The second handle is adapted to be located at a first position on the frame to allow a user to grasp the working head with a second hand away from a compression area between the ram and an opposite anvil section of the frame. The second handle is adapted to be repositioned on the frame to a second different position.
- The foregoing aspects and other features of the invention are explained in the following description, taken in connection with the accompanying drawings, wherein:
-
FIG. 1 is a side view of a hand-held tool incorporating features of the invention; -
FIG. 2 is a front view of the tool shown inFIG. 1 ; -
FIG. 3 is a side view of the tool shown inFIG. 1 with the front handle is a second position; -
FIG. 4 is a front view of the tool shown inFIG. 3 ; -
FIG. 5 is a side view of the tool shown inFIG. 1 with the front handle repositioned to another location; -
FIG. 6 is a front view of the tool shown inFIG. 5 ; -
FIG. 7 is a side view of the tool shown inFIG. 1 with the front handle repositioned to another location; -
FIG. 6 is a front view of the tool as shown inFIG. 2 with the front handle repositioned to the opposite side of the tool; and -
FIG. 9 is a perspective view of an alternate embodiment of the invention with a stationarily mounted front handle. - Referring to
FIG. 1 , there is shown a side view of ahydraulic tool 10 incorporating features of the invention. Although the invention will be described with reference to the exemplary embodiments shown in the drawings, it should be understood that the invention can be embodied in many alternate forms of embodiments. In addition, any suitable size, shape or type of elements or materials could be used. - The
tool 10 is a battery powered, hand-held hydraulic crimping tool adapted to crimp or compress an electrical connector onto an electrical conductor. The tool is adapted to have removable crimping dies (not shown) connected to its workinghead 12 to crimp the connector onto the conductor. However, in alternate embodiments, the tool could comprise permanent (non-removable) crimping surfaces or cutting dies to cut a conductor. - The
tool 10 generally comprises amain section 14 and the workinghead 12. Themain section 14 comprises anouter housing 16 surrounding ahydraulic drive system 18. The hydraulic drive system comprises anelectric motor 20, ahydraulic pump 22 connected to ahydraulic fluid reservoir 24, and a hydraulicfluid conduit system 26 such as in a frame of the main section. Themain section 14 also includes abattery 32 and a control system including actuation andrelease triggers housing 16 forms afirst handle 38 for a user to grasp the tool with a first hand. The first handle is rigid. Thetriggers first handle 38 for actuation by fingers of the user's first hand as the user is grasping thefirst handle 38 with the first hand. The components of the main section could comprise any suitable components known in the art. In alternate embodiments, any suitable type of main section could be provided. - The working
head 12 generally comprises aframe 34 and aram 36. In a preferred embodiment theframe 34 is rotatably connected to the front end of themain section 14. However, in an alternate embodiment theframe 34 could be stationarily connected to the front end of the main section. In this embodiment the frame has a general C shaped profile. However, in alternate embodiments any suitable shaped frame could be provided. Therear end 40 of theframe 34 has theram 36 movably located therein. Theram 36 is adapted to extend and retract relative to afront anvil section 42 of theframe 34 as indicated byarrow 44. Theram 36 is moved forward towards theanvil section 42 by hydraulic fluid from thehydraulic drive system 18 pressing against the rear end of theram 36. The ram is moved rearward, back towards a home position, by a return spring when the hydraulic fluid behind the ram is released back to thehydraulic fluid reservoir 24. Operation of the ram is convention and well known in the art. Theram 36 and theanvil section 42 are adapted to removably receive connector crimping dies (not shown) at mountingareas - Referring also to
FIG. 2 , in addition to theframe 34 and theram 36, the workinghead 12 includes asecond handle 50. Thesecond handle 50 is mounted to theframe 34. In this embodiment thesecond handle 50 is mounted to abottom side 52 of theframe 34. However, the second handle could be mounted at other locations as illustrated by the examples noted below. In this embodiment thesecond handle 50 comprises a mountingsection 54, a movement joint 56, and ahandle section 58. The mountingsection 54 preferably comprises a threadedsection 55 which screwed into a threaded hole in the bottom of theframe 34. However, in an alternate embodiment the mountingsection 54 could be integrally with theframe 34, such as an integrally formed mounting post. This could occur when themetal frame 34 is cast; perhaps with additional subsequent machining. - The movement joint 56 forms a pivoting hinge which movably connects the
handle section 58 to the mountingsection 54. This could be as simple as a pinned hinge connection, or could be more complex. For example, the movement joint 56 could comprise adetent locating system 60 to positively hold thehandle section 58 at one or more positions until positively moved by a user. However, a detent locating system need not be provided. In an alternate embodiment, additionally or alternatively, the movement joint 56 could comprise aposition locking system 61 to lock thehandle section 58 in a user selected angular position on the frame 34 (such as the first and/or second positions). In this type of embodiment thelocking system 61 would need to be manually unlocked by the user to move thehandle section 58 to another position on theframe 34. In addition, in an alternate embodiment the second handle might not comprise a movement joint. Thehandle section 58 could be stationarily connected to the mountingsection 54. - The
handle section 58 forms an area where a user can grasp thehandle 50 away from thecompression area 62 between theram 36 and theanvil section 42. In this embodiment thehandle section 58 is shown as a general rod shape. However, in alternate embodiments any suitably shaped handle section, to allow a second hand of the user to grasp the handle section, could be provided. - The provision of the
second handle 50 allows a user to grasp thetool 10 at the twohandles tool 10; especially if theframe 34 is a large size frame (for large size connectors) having a heavy weight compared to traditional such tools. Thesecond handle 50 is suitably located away from thecompression area 62 to help insure that the user's second hand will not be accidentally caught in thearea 62 during crimping. -
FIGS. 1 and 2 show thesecond handle 50 in a first position on theframe 34. In this first position thehandle 50 extends downward from thebottom side 52 of theframe 34 in a general cantilevered fashion. Referring also toFIGS. 3 and 4 , thesecond handle 50 is shown in a second position on theframe 34. In this second position thehandle 50 has been moved, from the extended first position shown inFIGS. 1 and 2 , to a storage position. The second storage position comprises thehandle section 58 being located underneath thebottom side 52, substantially parallel to thebottom side 52; rotated about 90 degrees from its first position. Movement of the second handle to its second position can allow thetool 10 to be stored more easily. In addition, thesecond handle 50 can be moved to its second position if the workinghead 12 needs to be inserted into a limited space work area; which thesecond handle 50 might otherwise prevent ifsecond handle 50 was located in its first position shown inFIGS. 1 and 2 . - Installing an assist handle onto the working head of a tool allows the user to handle the additional weight of a heavy working head more easily. The application of this handle can be somewhat flexible, in that it may need to have more than one installation location, and may need to fold flat for insertion in some working locations.
- The
frame 34 can comprise multiple mountinglocations 64 for mounting thesecond handle 50. In this embodiment the mountinglocations 64 comprise threaded holes along at least one lateral side of theframe 34. For example, as shown inFIGS. 5 and 6 , thehandle 50 could be mounted to the right side of thetool 10 on one of the mounting holes 64 on the right lateral side of theframe 34. The movement joint 56 could allow thehandle section 58 to be moved from its first extended position to a second non-extended position, such as shown by dotted lines inFIG. 5 orFIG. 6 .FIG. 7 shows thehandle 50 located at another different mounting location on the right side of theframe 34.FIG. 8 shows thehandle 50 mounted to another different mounting location on the left side of theframe 34. Comparison ofFIGS. 6 and 8 illustrate that thesecond handle 50 can be repositioned on theframe 34 for either a left handed or right handed user. In an alternate embodiment, thehandle 50 could be mounted to thebottom side 52 of theframe 34, and the movement joint 56 could be configured to allow thehandle section 58 to be located in the down position, at least one lateral position (left and/or right), and/or a folded flat position as shown inFIG. 3 . In another alternate embodiment, the movement joint 56 could be a universal type of joint allowing the handle section to be located at any suitable angular position relative to theframe 34 and having a position locking system to lock any specific angular location. - Referring also to
FIG. 9 , an alternate embodiment of the invention is shown. Thetool 70 generally comprises amain section 72, a workinghead 74 and anarm support 76. A similar arm support is described in U.S. patent application Ser. No. ______ filed May 14, 2007, (Attorney Docket No. 003B.0117.U1(US)) entitled “Tool Arm Support” which is hereby incorporated by reference in its entirety. In this embodiment the workinghead 74 is identical to the workinghead 12, except for thesecond handle 78. In this embodiment thehandle 78 has a mountingsection 54, such as a threaded end, and ahandle section 80, but does not include a movement joint. Thus, when the mountingsection 54 is connected to theframe 34, thehandle section 80 is stationarily mounted to theframe 34. However, thehandle 78 could be mounted to any of the mounting locations on theframe 34. Alternatively, the frame of the working head might only have one mounting location. - It should be understood that the foregoing description is only illustrative of the invention.
