This disclosure relates to carpentry tools and more specifically, carpentry tools and carpentry tool attachments that can be used to mark, measure, and, specifically, to make cuts in the field and/or at a job site.
Numerous tools have been used for measuring and marking workpieces for installation and assembly. Some of the roofing carpentry tools used for measuring and marking include indicia or markings to allow the user or carpenter to measure and mark the workpiece. The workpiece is then cut using a saw, for example, a circular saw, table saw, miter saw, or the like. For example, the carpentry tool can be a speed square that allows markings for 45 degree or 90 degree angles by placing the speed square on the workpiece, using an edge of the speed square to align the speed square, and making the appropriate marking for the desired cut. However, in order to perform the cut, the speed square is typically moved, e.g., moved a distance required to allow the saw to engage the workpiece, and the cut is started without a guide, e.g., free-hand. After the cut is initially made and the saw cuts a pre-determined distance into the workpiece, the speed square can then be used as a guide for the saw. While the speed square can be used to mark angles and/or guide the saw for 90 degree cuts, for any other angular cuts, the speed square is used to only make the markings and then removed. Then the entirety of the cut is made without a guide, e.g., free-hand, which is incredibly difficult to do well and consistently, which can lead to uneven cuts, loss of time, and/or lead to loss of material, e.g., waste.
In order to overcome one or more of the deficiencies of prior workpiece cutting tools, the carpentry tool and carpentry tool attachment as disclosed herein are at least directed to a portable device that may be used to cut a workpiece, that may be a replacement for a sliding or soffit cut table, which may be heavy, large, expensive, and fragile. Instead, the device as disclosed herein may be portable so that it may be brought to a workpiece material pile or at elevated worksites, such as, two story, three story, or the like worksites and/or on scaffolding. The carpentry tool and carpentry tool attachment may be used to provide straight cuts of any angle, e.g., precision and accurate cuts, that may eliminate the need for siding and/or soffit cut tables.
In some embodiments, the carpentry tool attachment may include a material guard that may include an adhesive, such as, self-adhesive, pressure-sensitive adhesive, or the like, that may be removably attachable to the carpentry tool attachment or the carpentry tool itself. The material guard may be used as a scratch guard for the workpiece it is placed on, e.g., from the carpentry tool, such as the blade guard, and/or be used as a set guide. The material guard may be disposable such that after the material guard is attached to the carpentry tool and used with a cutting tool, such as a miter saw or cut saw, and after the cutting tool is adjusted to a safe depth on a workpiece, a “dry run” cut may be made, in which any excess portion of the material guard may be removed, e.g., cut off, to provide an exact line of blade travel. The material guard may be used for the duration of the job to ensure accuracy of cuts and scratch resistance, such that future cuts and line ups are provided, and disposed as necessary.
In an embodiment, a carpentry tool attachment is provided. The carpentry tool attachment includes a main body comprising a top edge and a bottom edge. The top edge includes at least one attachment portion for attaching to a carpentry tool, and the bottom edge is configured to align a cutting device for cutting a workpiece.
The details of one or more embodiments of the disclosure are set forth in the accompanying drawings and the description, and from the claims.
References are made to the accompanying drawings that form a part of this disclosure, and which illustrate embodiments in which the systems and methods described in this specification can be practiced.
Like numbers represent like features.
This disclosure relates to carpentry tools and more specifically, carpentry tools and carpentry tool attachments that can be used to mark, measure, find an angle, and, specifically, make cuts in the field and/or at a job site, and more specifically to act as a guide to make angular cuts.
Currently, a device is not available for making repeatable and/or reproducible cuts, especially, in the field and/or at a job site, e.g., for cutting rafters or a multitude of workpieces at a house, barn, building, or the like. Rather, the current carpentry tools are only provided for making measurements and/or markings on the workpiece. The workpiece is then cut without a guide, e.g., free-hand, or after an initial cut is made free-hand, the carpentry tool can be used to make a 90 degree cut and 45 degree cuts in limited situations, e.g., using the carpentry tool as a cutting guide. While repeatable and/or reproducible cuts can be made if the workpiece, after marked in the field, is brought to a stationary saw, for example, a miter saw having a fixed cut angle, e.g., 40 degree to match an angle pitch of a roof, for example, a 4 to 12/12 roof pitch, or sliding or soffit cut table, such use of a stationary saw is not preferred at least because of the time and labor required to move the workpieces to the fixed location having the stationary saw. That is, the stationary saw cannot be brought up to the workpieces that need to be set in place and fixed before measurements, and then cut, sometimes one to two stories up in the house or building, since the stationary saw may be heavy, large, and fragile.
Embodiments of the present disclosure overcome such deficiencies by providing a carpentry tool that includes a main body that includes a first side and a second side, in which the first side and the second side each have a first end and a second end. The carpentry tool further includes an adjustable mechanism configured to adjust a cutting angle on a workpiece for a cutting device or tool and a lead guide segment connected to the end of at least one of the first side and the second side, in which the lead guide segment is configured to align the cutting tool for cutting the workpiece.
Further, a carpentry tool attachment is provided that may be used to extend at least a portion of the carpentry tool, e.g., the lead guide segment, for workpieces larger than the carpentry tool itself. The carpentry tool attachment includes a main body including a top edge and a bottom edge. The top edge includes at least one attachment portion for attaching to a carpentry tool and the bottom edge is configured to align a cutting device for cutting a workpiece.
As such, the carpentry tool and the carpentry tool attachment according to the embodiments discussed herein allow providing repeatable and/or reproducible cuts on a multitude of workpieces in the field, e.g., while at the roof under construction/repair, on scaffolding, or other work sites away from a preparation area, by having an adjustable and/or attachable mechanism to set the desired cutting angle and a lead guide segment to guide the cutting tool during an entirety of a cut, e.g., a cut square which avoids making a cut free-hand by acting as a cutting guide for the workpiece.
It is appreciated that the terms “connected,” “coupled,” “attached,” and the like are not intended to be limiting, but rather being used for discussion of the claimed features. As such, the terms are not intended to imply or suggest that the different features are different parts having multiple pieces that are connected, coupled, or attached, but rather, used to describe the different features of the carpentry tool, in which the carpentry tool can be formed as one piece or integrally formed having the different features, can be formed from several pieces, and/or can be used to describe the same part.
As illustrated in
In this embodiment, the first side 110 and the second side 120 have the second ends 112, 122 connected to third side 150 which forms a main triangular planar body 105, e.g., a right triangular body. The main triangular planar body 105 can have a thickness between about ⅛ to ¾ of an inch or similar (or 0.3175 centimeters to 1.9 centimeters) to provide sufficient strength for the carpentry tool and a surface for guiding the cutting tool. As such, the third side 150 is configured to guide the cutting tool, for example, by acting as a fence or guide to align the cutting tool when cutting the workpiece. It is appreciated that in an embodiment, the third side 150 can include a guide track for engaging the cutting tool, e.g., a lip or groove for engaging the baseplate or frame of the cutting tool.
The triangular planar main body 105 further includes a slide track 160 that extends along at least one of the first side 110 and/or the second side 120. In an embodiment, the slide track 160 can have a smooth, corrugated, ridged, or other designed track for engaging the adjustable mechanism 130. The slide track 160 can have a path that is parallel to the first side 110 and/or the second side 120, a path that is angular, a path that is part-elliptical, or a path that is part-circular, which is continuous or discontinuous between the first side 110 and the second side 120. It is understood that the term “part” is directed to describing a partial form of the geometric shape to define a path necessary to mark or identify the necessary angle to be cut and allow the functioning of the carpentry tool, as discussed below.
The first side 110, the second side 120, and/or the third side 150 can include incremental angle and/or length measurement indicia and/or similar measurement indicia to allow the user to mark, measure, and/or position the carpentry tool 100 for marking, measuring, and, especially, guided cutting of the workpiece. For example, in an embodiment, the length measurement indicia can be for lengths between about 5 inches and about 16 inches (or about 12.7 centimeters to 40.6 centimeters). The angles can include measurement indicia on, near, or adjacent the slide track and/or at a side edge of the first side 110, the second side 120, and/or the third side 150. The length measurements can be provided at the side edge of the first side 110, the second side 120, and/or the third side 150, in which the indicia can be perpendicular to the side edge, whereas, the angle indicia can be provided at an angle corresponding to the slide track 160. It is appreciated that the indicia can be provided on either a front planar side and/or on a back planar side of the carpentry tool 100.
The adjustable mechanism 130 can be an adjustable lever provided for adjusting a cutting angle for cutting, marking, and/or measuring a workpiece. The adjustable mechanism 130 can include a planar face having a width equal to or smaller than a width of the first side 110 or the second side 120. The adjustable mechanism/lever 130 is pivotally connected to the main triangular planar body 105 at a first end 131 and is slidably connected in the slide track 160 at a second end 132. The adjustable mechanism 130 can be connected to the main triangular planar body 105 and the slide track 160 using a fastener, such, as, a wing nut and bolt, a positioning pin or bolt, a knob and bolt, cam lock, or a combination thereof or a similar configuration that allows the tensioning and release of the adjustable mechanism 130 to adjust and fix the cutting angle for the workpiece. It is also appreciated that the first end 131 of the adjustable mechanism 130 can be fixed or permanently pivotally connected to the main triangular planar body 105, for example, using the bolts discussed above, or a rivet, push pins, or other fixing mechanism to fixedly connect the adjustable mechanism 130 to the main triangular planar body 105.

As further illustrated in
The carpentry tool 600 also includes an adjustable mechanism 630 for adjusting a cutting angle for cutting, marking, and/or measuring a workpiece. The workpiece can be cut using a hand-held cutting tool, for example, a skill saw, a hand-held saw, a circular saw, or the like. The carpentry tool 600 also includes a lead guide segment 640 connected to at least the first side 610 or the second side 620. The lead guide segment 640 can be provided to align and/or guide the cutting tool for cutting the workpiece.
The adjustable mechanism 630 can be an adjustable lever provided for adjusting a cutting angle for cutting, marking, and/or measuring a workpiece. The adjustable mechanism/lever 630 is pivotally connected to the main triangular planar body 605 at a first end 631 and is slidably connected in the slide track 660 at a second end 632 by slidable member 634. The adjustable mechanism 630 can be connected to the main triangular planar body 605 and the slide track 660 using a fastener, such as, a wing nut and bolt, a positioning bolt, a knob and bolt, cam lock, or a similar configuration that allows the tensioning and release of the adjustable mechanism 630 to adjust the cutting angle on the workpiece. It is also appreciated that the first end 631 of the adjustable mechanism 630 can be fixed or permanently pivotally connected to the main triangular planar body 605, for example, using the bolts discussed above, or a rivet, push pins, or other fixing mechanism to fixedly connect the adjustable mechanism 630 to the main triangular planar body 605.
In an embodiment, the adjustable mechanism 630 can include a second track 633 provided centrally in the adjustable mechanism/lever 630. The slidable member 634 is configured to slide along both the slide track 660 and the second track 633. In an embodiment, the slidable member 634 can be fastener, such as, a wing nut and bolt or cam-lock to allow the tensioning and release of the adjustable mechanism 630, the operation of which is discussed below.
The lead guide segment 640 is connected to the second side 620 and is formed, at least in part, by the third side 650, as schematically illustrated as the dashed line in
In operation of the carpentry tool 600, after the desired cutting angle is set by tensioning the slidable member 634, e.g., by providing a binding force between the adjustable mechanism 630 and the main body 605, the carpentry tool 600 can be used to make precise and repeatable angled cuts repetitively on a multitude of workpieces. For example, the carpentry tool 600 can be positioned on the workpiece in which one of the arms of the adjustable mechanism 630 is configured as an anchoring edge. As such, when the carpentry tool 600 is positioned on the workpiece, the carpentry tool 600 can be securely held against the workpiece such that the lead guide segment 640 and/or the third side 650 can be used as a guide or fence for the cutting tool to cut the workpiece.
Additionally, in view of the structure of the carpentry tool 600, after the carpentry tool 600 is positioned on the workpiece, the lead guide segment 640 extends from the workpiece such that the lead guide segment 640 has a sufficient length for guiding and/or aligning the cutting tool along the entirety of the cut. As such, unlike the prior designs of the speed square, the carpentry tool 600 as discussed herein is able to make repeatable, precise, and/or reproducible cuts in the field. Additionally, while prior carpentry tools can be used as a cutting guide, such prior carpentry tools were not able to adjust the angle of the cut, e.g., only making either making a 90 degree or 45 degree cut. The carpentry tool 600, however, includes the adjustable mechanism such that various cutting angles can be set to make the desired cuts, e.g., a 40 degree angle to match the pitch of a roof. It is also appreciated that at least in view of the structure of the adjustable mechanism 630, the carpentry tool 600 can be reversible such that either the front planar surface or the back planar surface can be positioned for use as a cutting guide.
The lead guide segment 740 is connected to the second side 720 and is formed, at least in part, by the third side 750, as schematically illustrated as the dashed line in
The carpentry tool 800 also includes an adjustable mechanism 830 for adjusting a cutting angle for cutting, marking, and/or measuring a workpiece. The carpentry tool 800 also includes a lead guide segment 840 connected to at least the first side 810 or the second side 820. The lead guide segment 840 can be provided to align and/or guide the cutting tool for cutting the workpiece. The workpiece can be cut using a hand-held cutting tool, for example, a skill saw, a hand-held saw, a circular saw, or the like.
The adjustable mechanism 830 is pivotally connected to the main triangular planar body 805 at a first end 831 and is slidably connected in the slide track 860 by slidable member 834. As such, the slidable member 834 can be adjusted in the slide track 860 to adjust the cutting angle of the carpentry tool 800 for cutting a workpiece. It is also appreciated that the first end 831 of the adjustable mechanism 830 can be fixed or permanently pivotally connected to the main triangular planar body 805, for example, using the bolts discussed above, or a rivet, push pins, or other fixing mechanism to fixedly connect the adjustable mechanism 830 to the main triangular planar body 805. In an embodiment, the adjustable mechanism 830 includes a first arm connected at the front planar surface of the carpentry tool 800 and a second arm (not shown) connected at the back planar surface of the carpentry tool 800. In an alternative embodiment, the adjustable mechanism 830 only includes a first arm and further includes a structure for engaging the workpiece, e.g., an anchoring edge, for example, a pin-like or needle-like structure, nuts, or an edge portion that extends towards the workpiece for engaging the same on the back planar surface to provide a more accurate alignment and/or measurement of a cutting angle.
The lead guide segment 840 can be connected to either or both the first side 810 or the second side 820 and can be formed, at least in part, by the third side 850. In an embodiment, the lead guide segment(s) 840 is a portion or segment of the carpentry tool that extends beyond a width of the workpiece and has sufficient length so that a hand-held cutting tool can engage the carpentry tool 800 for guiding of the same, e.g., a length greater than a distance between the saw or blade of the cutting tool and the base plate or frame. It is appreciated that when the carpentry tool 800 includes the lead guide segments 840 connected to the first side 810 and the second/third side 820/850, the carpentry tool 800 can be used to make either a right hand cut or a left hand cut. As such, the indicia on the slide track can correspond to the cutting angle for the right hand cut, whereas, indicia on a different portion of the main triangular planar body 805 can correspond to the cutting angle for a left hand cut. In an embodiment, the lead guide segment 840 can be adjustable between a working position or a folded position or integrally formed with the first side and/or second side.
As seen in
Similarly, if a left-hand cut is to be made on the workpiece, after the adjustable mechanism 830 is slid/repositioned in the slide track 860 to adjust the cutting angle for a left-hand cut angle, the slidable member 834 is tensioned to fix the adjustable mechanism 830 at the desired cutting angle. The carpentry tool 800 is then positioned on the workpiece to be cut, in which the adjustable mechanism 830 is configured as an anchoring edge for the workpiece. As such, when the carpentry tool 800 is positioned on the workpiece, the carpentry tool 800 can be securely held against the workpiece such that the lead guide segment 840 and the third side 850 can be used as a guide or fence for the cutting tool to cut the workpiece.
In an embodiment, a supporting structure 925 can be provided connecting the first side 910 and the second side 920. The supporting structure 925 can be made of the same material as the first side 910 and/or the second side 920. The supporting structure 925 can be connected to the first side 910 and the second side 920 via notches in either the supporting structure 925 or the first side 910 and the second side 920 or can be integrally formed, e.g., welding, casting, or the like, with the first side 910 and the second side 920. In an embodiment, the supporting structure 925 can have a thickness greater than the thickness of the first side 910 and the second side 920 and can define an anchoring edge on both the front planar side and the back planar side of the carpentry tool 900. It is appreciated that the front planar side can be a first planar surface that is opposite a second planar surface. For example, as seen in
The lead guide segment 940 can be connected to either or both the first side 910 and the second side 920. In an embodiment, the lead guide segment(s) 940 is a portion or segment of the carpentry tool that extends beyond a width of the workpiece and has sufficient length so that a hand-held cutting tool can engage the carpentry tool 900 for guiding of the same, e.g., a length greater than a distance between the saw or blade of the cutting tool and the base plate or frame. It is appreciated that the carpentry tool 900 can be used to make either a right hand cut or a left hand cut by the placement of the carpentry tool 900 having the desired cutting angle on the workpiece from either the front planar side, e.g., first planar surface, or the back planar side, e.g., second planar surface, such that the cut portion of the workpiece falls away from the workpiece.
In an embodiment, the carpentry tool 900 consists of the first side 910, the second side 920, the slide track 960, the lead guide segment 940, the slidable member 934, and optionally the supporting structure 925. As such, the carpentry tool 900 has a lighter weight since it does not form a planar and triangular main body and further provides an improved handling since the user or carpenter can grasp the first side 910 or the second side 920.
In operation of this embodiment, as illustrated in

The main body 1210 may be generally planar for providing the track or guide for the cutting tool for cutting the workpiece (or grinding tool for grinding the workpiece) that may serve as an extension or additional component of the carpentry tool. The main body 1210 includes a top edge 1212 and a bottom edge 1214, in which the top edge 1212 is configured to interface and/or attach to the carpentry tool, and the bottom edge 1214 is configured as the track or guide for the cutting tool or grinder tool for processing the workpiece.
The one or more attachment portions 1220 may generally extend from the top edge 1212 of the main body 1210. The attachment portions 1220 may include tabs or hooks 1222, e.g., ear tabs, for connecting to the main body of the carpentry tool, and a fastening portion 1224 for securing and/or connecting the carpentry tool attachment to the carpentry tool. In some embodiments, the tabs or hooks 1222, e.g., the ear tabs, may have a profile corresponding to sides of the main body of the carpentry tool, e.g., angled to match the angle(s) of the main body of the carpentry tool, for affixing the carpentry tool attachment to the carpentry tool. The tabs or hooks 1222 may further include an overhanging portion for providing secured engagement or connection to the main body of the carpentry tool, e.g., hooking portion that engages over the sides of the main body of the carpentry tool. In another embodiment, the carpentry tool attachment may include a series of lock ear tabs and straight 90-degree keeper tabs as a quick release/detach feature which may include the keeper screw or may not include the keeper screw, e.g., tensioned to the carpentry tool using a cam lock, spring, clip, clasp, or other tensioning device for engaging or connecting to the main body of the carpentry tool. In some embodiments, the tabs 1222 may include a hole, slot, or opening that corresponds to a hole, slot, or opening on the carpentry tool for receiving a fastener, such, as, a keeper screw may include one threaded hole, threaded insert stamped into plate/flush screw head with nut at top, a nut and bolt, wing nut and bolt, positioning needle and nut, cam-lock, bolt, or other similar fastening means.
The fastening portion 1224 may extend from the top edge 1212 of the main body 1210 and may include a hole, slot, or opening for securing and/or connecting the carpentry tool attachment to the carpentry tool. The fastening portion 1224 may be configured to receive a fastener, such as, a keeper screw that may include one threaded hole, threaded insert stamped into plate/flush screw head with nut at top, a nut and bolt, wing nut and bolt, positioning needle and nut, cam-lock, bolt, or other similar fastening means, that may be used to secure the carpentry tool attachment to the carpentry tool.

That is, the carpentry tool attachment 1200 may be used as a track or guide for a cutting device, such as, a circular saw, in which the circular saw base plate may be “guided over” the workpiece, such as, I-beams, vinyl siding, soffits, corrugated steel, or the like. At least in view the extension surface provided by the carpentry tool attachment 1200 to the carpentry tool 600, the carpentry tool attachment 1200 may allow a consistent cutting method/motion by allowing an application of even and accurate pressure while pushing the circular saw during the cutting process without the unsafe ups and downs and variances caused by following the surface of workpiece. As such, the carpentry tool attachment 1200 may be used on even or uneven surfaces of various workpieces to allow a consistent and even cut and/or provide stabilization for providing an even cutting surface, e.g., for uneven cutting surfaces, such as, corrugated steel, I-beams, or the like.
While the carpentry tool attachment 1200 has been discussed above with respect to carpentry tool 600, such disclosure is not intended to be limiting. Rather, it is appreciated that the carpentry tool attachment 1200 may be designed for various carpentry tools and/or designed or otherwise configured to be adjustable, e.g., pivotable attachment portions 1220, for use universally with carpentry tools.
For example, as illustrated in
As illustrated in
The carpentry tool attachment 1600 may include a main body 1610 and one or more attachment portions 1620 extending from the main body 1610. The main body 1610 may include a first side 1611 and a second side 1613 that may be connected at an angle, e.g., depending on the carpentry tool, for example, a right angle for the framing square 1690. The second side 1613 may include a bottom edge 1614 for providing the track or guide for the cutting tool for cutting the workpiece (or grinding tool for grinding the workpiece) that may serve as an extension or additional component of the framing square 1690.
The one or more attachment portions 1620 may generally extend from the first side 1611 and the second side 1613 of the main body 1610. The attachment portions 1620 may include tabs or hooks 1622, e.g., ear tabs, for connecting to the carpentry tool, and a fastening portion 1624 for securing and/or connecting the carpentry tool attachment to the framing square 1690. In some embodiments, the tabs or hooks 1622 may be ear tabs corresponding to a first side 1692 and a second side 1694 of the main body of the framing square 1690 for affixing the carpentry tool attachment 1600 to the framing square 1690. The tabs or hooks 1622 may further include an overhanging portion for providing secured engagement or connection to the first side 1692 and the second side 1694 of the main body of the carpentry tool 1690, e.g., hooking portion or channel that engages over the sides of the main body of the framing square 1690. In another embodiment, the carpentry tool attachment may include a series of lock ear tabs and straight 90-degree keeper tabs as a quick release/detach feature which may include the keeper screw or may not include the keeper screw, e.g., tensioned to the carpentry tool using a cam lock, spring, clip, clasp, or other tensioning device for engaging or connecting to the main body of the carpentry tool. In some embodiments, the tabs 1622 may include a hole, slot, or opening that corresponds to a hole, slot, or opening on the carpentry tool for receiving a fastener, such as, a keeper screw that may include one threaded hole, threaded insert stamped into plate/flush screw head with nut at top, a nut and bolt, wing nut and bolt, positioning needle and nut, cam-lock, bolt, or other similar fastening means.
The fastening portion 1624 may extend from one of the first side 1611 or the second side 1613 of the main body 1610 and may include a hole, slot, or opening for securing and/or connecting the carpentry tool attachment to the framing square 1690. The fastening portion 1624 may be configured to receive a fastener, such as, a keeper screw that may include one threaded hole, threaded insert stamped into plate/flush screw head with nut at top, a nut and bolt, wing nut and bolt, positioning needle and nut, cam-lock, bolt, or other similar fastening means, that may be used to secure the carpentry tool attachment to the carpentry tool. The fastening portion 1624 may be designed or otherwise configured such that the keeper screw is provided below a bottom edge of the first side 1692 or second side 1694 of the framing square 1690 or to engage the planar surface or hole thereon of the first side 1692 or second side 1694 of the framing square 1690.
In some embodiments, the carpentry tool attachment 1600 may include the slide track 1626 that that extends between the first side 1611 and the second side 1613. In an embodiment, the slide track 1626 can have a smooth, corrugated, ridged, or other designed track for engaging a slidable member that is configured to slide along the slide track 1626. In an embodiment, the slidable member can be fastener, such as, a wing nut and bolt or cam-lock to allow the adjustment of an angle of the combination of the framing square 1690 having the carpentry tool attachment 1600.
In some embodiments, as illustrated in
As illustrated in
As such, after the desired cutting angle is set by tensioning the slidable member in the slide track 1626, the combination of the framing square 1690 and the carpentry tool attachment 1600 can be used to make precise and repeatable angled cuts repetitively on a multitude of workpieces. Thus, when the combination of the framing square 1690 and the carpentry tool attachment 1600 is positioned on the workpiece, the combination of the framing square 1690 and the carpentry tool attachment 1600 can be securely held against the workpiece such that the bottom edge 1614 of the carpentry tool attachment 1600 can be used as a guide or fence for the cutting tool to cut the workpiece, e.g., for workpieces larger than the framing square 1690 itself.
That is, the carpentry tool attachment 1600 may be used as a track or guide for a cutting device, such as, a circular saw, in which the circular saw base plate may be “guided over” the workpiece, such as, I-beams, vinyl siding, soffits, corrugated steel, or the like. At least in view the extension surface provided by the carpentry tool attachment 1600 to the framing square 1690, the carpentry tool attachment 1600 may allow a consistent cutting method/motion by allowing an application of even and accurate pressure while pushing the circular saw during the cutting process without the unsafe ups and downs and variances caused by following the surface of workpiece. As such, the carpentry tool attachment 1600 may be used on even or uneven surfaces of various workpieces to allow a consistent and even cut and/or provide stabilization for providing an even cutting surface, e.g., for uneven cutting surfaces, such as, corrugated steel, I-beams, or the like.
An adjustable mechanism is provided by slidably connecting slidable member 1734 in the slide track 1760. In some embodiments, the slidable member 1734 may be a fastener, such as, bolt and nut, wing nut, setting screw, cam fitting, or the like.
As illustrated in
The carpentry tool attachment 1700 may be connected to the carpentry tool 1790 along a third side of the carpentry tool 1790 such that the carpentry tool attachment 1700 may serve or act as an extension of the carpentry tool 1790. The carpentry tool attachment 1700 may be attached to the carpentry tool 1790 using an adhesive, welding, or fasteners, such as, screws, bolts, lock nuts, or the like. In some embodiments, the carpentry tool attachment 1700 may include a clamping structure for being attached to the carpentry tool 1790, e.g., via tensioning of the fasteners.
In some embodiments, the carpentry tool attachment 1700 and/or the carpentry tool 1790 may include a material stop or abutment surface 1728. The material stop or abutment surface 1728 may be provided on a back surface of the carpentry tool 1790 for abutting against the workpiece, e.g., to provide a straight edge. The material stop or abutment surface 1728 may be attached or affixed to the carpentry tool 1790, e.g., glueing, welding, or the like, or may be integrally formed with the carpentry tool 1790.
In some embodiments, the combination carpentry tool attachment 1700 and carpentry tool 1790 may further include a handle or knob 1796 for positioning and/or maintaining the combination when cutting a workpiece.
As such, the combination of the carpentry tool attachment 1700 and the carpentry tool 1790 may be provided such that the bottom edge 1714 of the carpentry tool attachment 1700 may serve as the cutting guide or set guide for the carpentry tool 1790 to extend the carpentry tool 1790, e.g., serves as an extension portion for cutting, measuring, and/or grinding larger workpieces.
As further illustrated in
In some embodiments, the material guard 1895 may have the same size or may be larger than the carpentry tool attachment 1200, e.g., longer and wider, such that the material guard 1895 may be cut to remove excess portions to determine the exact line of blade travel, e.g., when the cutting tool is a miter saw. The material guard 1895 may be formed from plastic, paper, PVC, and/or composite such that the material guard 1895 may be soft and have non-abrasive properties, but configured to be cut cleanly and to be flexible. In some embodiments, the material guard 1895 may include a foam layer that is attached to the bottom or underside of the material guard 1895. As such, the foam layer may provide additional grip for gripping to the workpiece(s), when pressure is applied downward on the material to be cut.
It is appreciated that at least in view of the structure of the carpentry tool 100, 600, 700, 800, 900, 1790 and/or carpentry tool attachment 1200, 1600, 1700 as described herein, the carpentry tool and/or carpentry tool attachment have a number of advantageous benefits.
For example, the carpentry tool and/or carpentry tool attachment, as discussed herein, have a configuration that allows a guided cutting of a workpiece in the field such that repeatable and reproducible angular cuts can be made to a multitude of workpieces. That is, the carpentry tool and/or carpentry tool attachment, as disclosed herein, can be used to provide a fixable angle guide for cutting the workpiece by simply and quickly adjusting the adjustable mechanism to at least provide fast and factory quality miter cuts or angle cuts without a miter saw or other stationary saw, e.g., siding or soffit cut table.
The carpentry tool and/or carpentry tool attachment also avoid any free-hand cutting, e.g., guideless cutting, of the workpiece by the cutting tool, at least because the lead guide segment (or carpentry tool attachment) hangs below or extends beyond the width of the work piece, e.g., provides a guide so that the blade of the cutting tool can engage the workpiece to provide cleaner and straighter cuts.
The carpentry tool and/or carpentry tool attachment also safely keep hands farther away from the cutting tool.
In some embodiments of the carpentry tool, the carpentry tool is reversible such that either side or planar surface of the main body can be available for guiding the cutting of a workpiece. For example, the carpentry tool can be flipped from a front planar side for making a right hand cut, e.g., so the cut piece of the workpiece falls away to the right and away from the remainder of the workpiece, to a back planar side for making a left hand cut, so that the cut piece of the workpiece falls away to the left and away from the remainder of the workpiece. In another embodiment, the carpentry tool can be used on a top edge or a bottom edge of the workpiece for cutting and/or marking.
