DETAILED DESCRIPTION OF THE INVENTION
Before describing the disclosed embodiments of this technology in detail, it is to be understood that the technology is not limited in its application to the details of the particular arrangement shown here since the technology described is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.
In various exemplary embodiments, the technology described herein provides a reciprocating cutter for use in spaces where a typical saw is unable to operate due to size, space, and operability limitations. Additionally, the technology described herein provides a reciprocating cutter having a spring-loaded handle, cable saw, and connectivity bit for coupling to a reciprocating saw or like device. Furthermore, various embodiments include a cable saw cutter system that is used many times and in which the cable portion is interchangeable and replaceable, a disposable cable saw cutter system, and a complete cable saw system that also includes a reciprocating device.
Referring now to the figures, a reciprocating cutter system 10 is shown. The reciprocating cutter system 10 is configured for use in spaces where a typical saw is unable to operate due to size, space, and operability limitations.
The reciprocating cutter system 10 includes a housing 17. In at least one embodiment, the housing 17 is metal. In at least one embodiment, the housing 17 is plastic and transparent such that one can observe the internal workings, such as the spring 43 extending and retracting in action. The housing 17 is comprised of a sturdy, rigid material for use with power tools such as a reciprocating device 50, for example. The housing 17 provides an enclosure for system elements defined below, and is designed to regular use with the reciprocating device 50.
The reciprocating cutter system 10 includes a handle 12 securely disposed on a top portion of the housing 17 to provide an operator a user grip to operate the system. The handle 12 includes in at least one embodiment a pair of handle flanges 14 or wings with which a user can grip the handle 12. The handle 12 is metal and solid in at least one embodiment. The handle 12 is a sturdy plastic material in at least one alternative embodiment.
In at least one embodiment, the handle is a loop handle 13, as is depicted specifically in FIG. 6. In this embodiment, the handle 13 can be a wire 80. The loop handle 13 is coupled to the housing 17 and fastener 15, which securely holds the handles to the housing. The embodiment can further include a protective sheath 81 to cover the wire 80 loop handle 13 and protect the hand of the operator from wear.
The reciprocating cutter system 10 includes a cable saw 26 coupled to the housing 17 of reciprocating cutter system 10 via an anchor and spring, defined below. The cable 26 is a wire saw in at least one embodiment. The cable saw 26 is the key cutting component of the devices and systems disclosed herein. As the cable saw 26 is moved rapidly in a back-and-forth manner, such as when coupled to reciprocating device 50, the cable saw provides a cutting action on an item.
By way of example, in plumbing, one can use the reciprocating cutter system 10 to cut a PVC pipe, for example. The reciprocating cutter system 10 provides a means to rapidly cut such a PVC pipe, and enable the operator to do so in places where a traditional reciprocating saw, or the like, would not have adequate space in which to operate safely and properly.
In various embodiments, the cable saw 26 is a more permanent solution with the wire itself being replaceable and interchangeable as needed. In alternative embodiments, and as will be discussed below, the cable saw 26 is disposable after a certain number of uses or hours. In various embodiments, the cable saw 26 can vary in gages of wire used. Additionally, in various embodiments, the cable saw 26 can include additional cutting aids, such as bits, for example.
In various embodiments, the cable saw 26 includes fasteners. By way of example, first fastener 24 is coupled to cable saw 26 and provides a means by which the cable saw 26 base end 38 is coupled within the cable guide 40 and secured with first pin 20. Also, by way of example, the second fastener 28 is coupled to the cable saw 26 and provides a means by which the cable saw 26 is coupled to the connectivity bit 32 and secured with second pin 30.
The reciprocating cutter system 10 includes a spring 43 securely disposed within the housing 17 and coupled to the cable saw 26. As the cable saw 26 is moved in a back-and-forth motion when in use, such as when pulled by reciprocating device 50 depicted in FIG. 5, the spring 43 also moves in a back-and forth-motion without the operator-held handle 12 needing to move. The spring-loaded handle 12 thus provides the operator a means by which to “hold” the end of the cable saw opposite the reciprocating device 50, and the spring 43 contained within the housing is a shock absorber and enabler for the back-and-forth reciprocating motion. Spring stop washer 41 disposed between spring 43 and cable guide 40 prevents the spring 43 from being overextended. Rivets 18 hold the end cap 22 in place but do not impact movement of the anchor 42 going back and forth when the device is in use. Pin 16 holds a base in place to which the spring 43 attaches below the handle portion. That end of the spring 43 is generally fixed in terms of movement, while the other end of spring 43 moves back and forth, from which the cable saw 26 pulls, when the device is in use and the cable saw 26 is reciprocating.
The reciprocating cutter system 10 includes a connectivity bit 32. The connectivity bit 32 is depicted in close-up view in FIG. 4. The connectivity bit 32 is coupled to the cable saw 26 and connect the cable saw 26 through the connectivity bit 32 to a reciprocating device 50. The reciprocating device 50 provides the back-and-forth motion to the connectivity bit 32 and therefore the cable saw 26. In at least one embodiment, the cable saw 26 and the connectivity bit 32 are integrally formed and used as a single item.
In at least one embodiment, the connectivity bit 32 further includes an aperture 36. The aperture 36 enables the connectivity bit 32 to be coupled to the reciprocating device 50 to lock in place the connectivity bit 32 to the reciprocating device 50. The aperture 36 is designed to enable an operator to quickly and easily interchange the connectivity bit 32 with the reciprocating device 50.
In at least one embodiment, the connectivity bit 32, which coupled to the cable saw 26, is generally cylindrical on a first end (near 32) to receive the cable saw 26 and fastener 28, and held in place by pin 30, and substantially flat on a second end 34 for placement within a receiving area the reciprocating device 50. Between the cylindrical area (near 32) and the substantially flat end 34 is a gentle taper going from the cylindrical shape to the flat element.
In at least one embodiment, the reciprocating cutter system 10 includes a first pin 20 with which to couple the cable saw 26 to the housing 17 of reciprocating cutter system 10. The reciprocating cutter system 10 also includes a second pin 30 with which to couple the cable saw 26 to the connectivity bit 32 to connect the cable saw 26 to the reciprocating device 50. The cable saw 26 is thus interchangeable and replaceable in this embodiment. In alternative embodiments, the cable saw 26 is integrally formed with the connectivity bit 32. In alternative embodiments, the cable saw 26 is integrally formed with the housing 17.
The reciprocating cutter system 10 includes an end cap 22 securely disposed about a circumference of the housing 17 at a distal end of the housing 17 from the handle 12. The end cap 22 provides a backstop to the spring 43 securely disposed within the housing 17. The end cap 22 further defined by an aperture in the center of the end cap 22. The aperture is of a diameter just larger than that of the cable saw 26 such that the cable saw 26 feeds through the aperture to couple to the spring 43 securely disposed within the housing 17. The end cap 22 is held in place by rivets 18, as shown in FIG. 3.
The reciprocating cutter system 10 includes a cable guide 40. The cable guide 40 is securely disposed to the end cap 22 at the distal end of the housing 17. The cable guide 40 provides a guide to the cable saw 26 as the cable saw 26 moves in the back-and-forth motion, as reciprocated by the reciprocating device 50 for example, within the end cap 22 of the housing 17. The cable guide 40 therefore aids in the prevention of wear by the cable saw 26 to the end cap 22.
The reciprocating cutter system 10 includes an anchor 42 disposed within the housing 17. The anchor 42 is configured to fasten securely the cable saw 26 to the spring 43, as shown for example in FIG. 3 where near stop washer 41 the spring 43 is coupled to the anchor 42 where at least one thread or rotation of the spring is within an aperture of the anchor 42. The anchor 42 is comprised of a sturdy metal in at least one embodiment.
As depicted in FIG. 6, the reciprocating cutter system 10 in at least one embodiment is a disposable version. The disposable version of the reciprocating cutter system 10 is configured for use in spaces where a typical saw is unable to operate due to size, space, and operability limitations and once used a certain numbers of times or a certain number of hours is disposable.
The disposable reciprocating cutter system includes: a housing 17; a loop handle 13 securely disposed on a top portion of the housing to provide an operator a user grip to operate the system; a cable saw 26 coupled to the housing of reciprocating cutter system; a spring 43 (within the housing 17, but as shown in FIG. 3) securely disposed within the housing 17 and coupled to the cable saw 26 at 82 such that as the cable saw 26 is moved in a back-and-forth motion when in use, the spring 43 also moves in a back-and forth-motion without the operator-held handle needing to move; and a cable guide 40 securely disposed to the end cap 22 at the distal end of the housing 17 to provide a guide to the cable saw 26 as the cable saw 26 moves in the back-and-forth motion within the end cap 22 of the housing 17 and to prevent wear by the cable saw 26 to the end cap 22; and a connectivity bit 32 integrally formed with the cable saw 26, to connect the cable saw 26 through the connectivity bit 26 to a reciprocating device 50, the reciprocating device 50 to provide the back-and-forth motion to the connectivity bit and therefore the cable saw 26. In this disposable embodiment, the cable saw 26 is utilized without coupling pins and is disposable. Rivets 16, 18 or the like are utilized instead of pins.
In this embodiment, the disposable reciprocating cutter system includes a fastener 15. The fastener 15 secure the loop handle 13 to the housing 13. Additionally, elements that can be included in the disposable version have been defined previously in regard to the non-disposable version.
In another exemplary embodiment, a complete reciprocating cutter system for use in spaces where a typical saw is unable to operate due to size, space, and operability limitations also includes a reciprocating device.
In this complete system embodiment, the reciprocating cutter system 10 includes: a power-driven reciprocating tool 50 to provide a back-and-forth motion; a housing 17; a handle 12 disposed on a top portion of the housing 12 to provide an operator a user grip to operate the system; a cable saw 26 coupled to the housing 17 of reciprocating cutter system; a spring 43 securely disposed within the housing 17 and coupled to the cable saw 26 such that as the cable saw 26 is moved in the back-and-forth motion when in use coupled to the power-driven reciprocating tool, the spring 43 also moves in a back-and forth-motion without the operator-held handle needing to move; and a connectivity bit 32, coupled to the cable saw 26, to connect the cable saw 26 through the connectivity bit 32 to the power-driven reciprocating tool 50, the power-driven reciprocating tool 50 to provide the back-and-forth motion to the connectivity bit and therefore the cable saw.
