(50) The examples in this document relate to the task of associating two wooden components together using an attachment-element (e.g. associating a joist to a ledger board via a joist hanger). It should be appreciated, however, that such tool can be used to associate any type of attachment-element to any type of support structure constructed from any type of material without departing from the scope and spirit of the invention.

DESCRIPTION

(51) Referring now to FIG. 1, a carpenter (6) is presented associating two wooden components (first structure (10) and second structure (14)) together using an attachment-element (20) according to one exemplary prior art method. For such example, first structure (10) is a ledger board and second structure (14) is a joist and attachment-element (20) is a joist hanger. Carpenter (6) first toenails a joist (14) using nail (18) to ledger (10) being careful to associate the joist to the ledger board so that the joist top edge (16) is level with the ledger top edge (12). The next step is to associate a joist hanger (20) tightly around the joist (14) and then drive speed prongs (21, FIG. 3) into the ledger board to temporarily hold the joist (14) in place (while making sure the joist is sitting squarely in the joist hanger without gaps alongside and under the joist). The final step is to associate the joist hanger (20) to the wall ledger (10) and the joist (14) by driving nails into predefined holes defined by the joist hanger.

(52) Referring now to FIG. 2 through FIG. 10, one exemplary embodiment of tool (30) configured for associating an attachment-element (20, FIG. 3) to a first structure (12) is presented. For the currently preferred embodiment, tool (30) comprises a handle-portion (36) and opposing interface-portion (38) defining width (38w, FIG. 6). The handle-portion (36) defines a handle top end (36a) and an opposing handle bottom end (36b) and the interface-portion (38) further defines an interface-top-end (38a) and an opposing interface-bottom-end (38b).

(53) Tool (30) further comprises top-portion (42) and bottom-portion (44) wherein said top-portion (42) mechanically associates handle top end (36a) to interface-top-end (38a) and bottom-portion (44) mechanically associates handle bottom end (36b) to the interface-bottom-end (38b). As shown in FIG. 4, a tool-void (40) is defined between the handle-portion, interface-portion, top-portion, and the bottom-portion.

(54) For the exemplary embodiment depicted in FIG. 4-FIG. 10, an alignment-element (32) is defined by, and is integral to, the bottom-portion and extends perpendicularly away from the interface-portion (38). Such alignment-element (32) may be (a) integral to said bottom-portion, (b) integral to said interface-portion, (c) mechanically associated with said bottom-portion, and (d) mechanically associated with said interface-portion.

(55) It will be appreciated that for the currently preferred embodiment, as depicted in FIG. 4 through FIG. 10, the tool, including the alignment-element, is molded from a composite material to define one integral component. That said, for one alternative embodiment, any combination of the various portions may be any number of separate components that are mechanically associated together to form tool (30). Notably, the handle-portion, interface-portion, top-portion, and bottom-portion each define a plurality of portion-voids (35, FIG. 5). Such portion-voids reduce the amount of material required to form tool (30) an also reduces the tool's weight and may define interfaces for receiving/storing items.

(56) For the currently preferred embodiment, running along the sides of interface-portion (38) are gap-setters (33) defining slots (37) configured to maintain a desired flange gap (25, FIG. 3) (described in more detail below). As best seen in FIG. 6, interface-portion (38) defines a flat surface having an interface-portion-width (38w) that is about equal to the flange gap (25) defined by attachment-element (20). One of ordinary skill in the art will appreciate that flange gap (25) will be equal to or slightly wider than the width (17) of second structure (14, FIG. 1). Stated differently, interface-portion (38) preferably defines an interface-portion-width (38w) that is substantially equal to the width (17) defined by second structure (14). Gap-setters (33) define slots (37) configured to receive and hold the attachment-element (20) flanges (i.e. flange (23a) and flange (23b) FIG. 3) adjacent to interface-portion (38) to maintain the desired flange gap. Notably, gap-setters (33) may define a magnetic element (such as a rare earth magnet) associated with a portion-void (35) defined by interface-portion (38). Such magnetic element would attract and hold the flanges against the sides of interface-portion (38b).

(57) In fact, one of ordinary skill in the art will further appreciate that where the attachment-element (20) is a joist hanger comprising a bottom plate (22) mechanically associated with a left side flange (23a) and a right side flange (23b) as depicted in FIG. 3, the gap setter (33) is configured to receive such flanges so that joint hanger bottom plate (22) is in alignment with said alignment-element (32) when the attachment-element is associated with tool (30) as depicted FIG. 2.

Tool Accessories

(58) As best seen in FIG. 32 and FIG. 33, electronic measurement module (50) defines one tool accessory configured for being mechanically associated with tool (30) to provide measurement data including leveling data and distance data. Yet another tool accessory is magnetic element (46) configured for being associated with a portion-void as depicted in FIG. 14. Such magnetic element (46) may be a rare earth magnet that is suitable for holding ferrous objects such as nails, screws, drill bits, etc. and can be further used to stow tool (30) against a ferrous object.

(59) Electronic module (50) is preferably configured to provide leveling data. A first leveling data relates to the vertical alignment of first structure (10, such as a ledger board). As depicted in FIG. 33a-FIG. 33d, for one preferred embodiment electronic module (50) is configured with a display (52) to provide a structure-alignment gauge (54) configured to provide an indication of whether or not the first structure is in vertical alignment with the gravity. The structure-alignment gauge (54) defines an F forward tilt, a plumb/vertical indicator, and a B backward tilt indicator. As depicted in FIG. 33a and FIG. 33b, structure-alignment gauge (54) may also provide a digital readout of the alignment angle such as the 1.1 degrees tilt back as indicated in FIG. 33b.

(60) A second leveling data relates to the vertical alignment of the attachment-element (20) relative to a surface/edge of first structure (10). For such currently preferred embodiment, display (52) further provides an attachment-element-alignment gauge (56) to provide an indication of whether or not the attachment-element (20) is in vertical alignment with a surface/edge defined by first structure (10). The attachment-element-alignment gauge (56) defines an L left tilt, a plumb/vertical indicator, and an R right tilt indicator. Attachment-element-alignment gauge (54) may also provide a digital readout of the alignment angle such as the 0.5-degree Left Tilt as indicated in FIG. 33b.

(61) For such feature, interface-portion (38) is placed flat against the appropriate surface of first structure (10) (as depicted in FIG. 2). If the structure (10) and attachment-element (20) are both in vertical alignment, display (52) provides the leveling data depicted in FIG. 33d.

(62) If the top edge of structure (10) and bottom edge of structure (10) are not in vertical alignment with gravity and the top edge tilts away from tool (30) the level icon is shifted to the F position (FIG. 33a) and a digital value is given (e.g. 3.3. degrees). If the bottom edge of structure (10) tilts away from tool (30), the level icon is shifted to the B position (FIG. 33b) and a digital value is given (e.g. 0.5 degrees). If the top edge and bottom edge of first structure (10) are in vertical alignment with gravity, structure-alignment gauge (54) indicates a plumb/vertical alignment as depicted in FIG. 33c and FIG. 33d. Such data allow one to establish a grade if desired.

(63) Similarly, for the attachment-element (20), if the top edge of the attachment-element (20) is to the left of the bottom edge of the attachment-element (20), the attachment-element (20) is said to tilt to the left and attachment-element-alignment (56) icon is shifted to the L position (FIG. 33b) and a digital value is given (e.g. 0.5 degrees). If the top edge of the attachment-element (20) is to the right of the bottom edge of the alignment-element (20), the attachment-element (20) is said to tilt to the right and attachment-element-alignment (56) icon is shifted to the R position (FIG. 33c) and a digital value is given (e.g. 2.6 degrees).

(64) For yet another alternative embodiment, electronic module (50) is preferably configured to provide distance data. For the currently preferred embodiment, a distance sensor determines the distance to an adjacent structure. Such sensor can be sound or electromagnetic based, (e.g. lasers, radio frequency, etc.).

(65) As before, interface-portion (38) is placed flat against the appropriate surface of first structure (10) (as depicted in FIG. 2). The distance sensor is then activated (if not already active) to determine the distance to an adjacent structure and presents the distance data via distance-display (58). The tool (30) can then be moved along structure (10) until the desired gap between adjacent structures is achieved. Notably, electronic module (50) may include a left and a right distance sensor and display a left distance and a right distance and such sensors may be configured to activate simultaneously or one at a time. Simultaneous operation is useful to find the center point between two structures.

(66) One of ordinary skill in the art will appreciate that electronic module (50) may be replaced with non-electronic sensors such as bubble levels and tape measures and telescoping rods. Additionally, other electronic modules or functions may be provided such as a stud finder function.

Method of Associating Attachment-Element

(67) Referring now to FIG. 2 and FIG. 3, FIG. 2 presents one exemplary embodiment of a tool (30) being used to associate an attachment-element (20) with a first structure. Notably, no tool accessories are used by the currently preferred method. FIG. 3 shows the exemplary attachment-element (20) (joist hanger) after being associated with first structure (10). For the current exemplary method, attachment-element (20) is a joist hanger comprising a bottom plate (22) mechanically associated with a left side flange (23a), a right-side flange (23b) (referred to collectively as side flanges), and a left front plate (26-LFP) and a right front plate (26-RFP) extending perpendicularly from said flanges respectively.

(68) First, an alignment mark is manually measured indicating the desired position along structure (10) to position joist hanger (20). Such measured location defines an A-axis location (alignment-mark (11)) on a structure where an attachment-element (20) is to be positioned. Second, a joist hanger (20) is associated with tool (30) so that the flanges are received by gap-setters (33). Restated, one configures a tool to receive an attachment-element (20) wherein said tool is associated with an alignment-element (32 or 32b) configured for being associated with an edge (alignment point, e.g. point 13, FIG. 2) defined by the first structure (10) thereby defining a B-axis location on structure (10) where said attachment-element is to be positioned. Using tool (30), the front plates (26) are brought in contact with a surface of first structure (10) (wall ledger for this example) and into alignment with alignment mark (11) as depicted in FIG. 2. The alignment-element (32) is then associated with the appropriate alignment point defined by structure (10). For the current example, the alignment point is first structure bottom edge (13). Front plates (26) are then secured to the surface of first structure (10) and tool (30) is removed as depicted in FIG. 3.

(69) The next step is to insert an end of second structure (14) between the flanges of joist hanger (20) so the bottom edge of second structure (14) is adjacent to bottom plate (22). Flanges (26) are then secured to second structure (14).

(70) It should be appreciated that the flange gap (25) is slightly larger than the width (17) of second structure (14) so that second structure (14) can be inserted into such flange gap so that the bottom defined by the second structure can rest on bottom plate (22) thereby minimizing the gap between the sides flanges of second structure (14) and aligning the first and second structure so that first structure top edge (12) is level with second structure top edge (16) as depicted in FIG. 1.

(71) For tool (30) embodiments configured with an electronic measurement module (50), the method is the same as above except for the step of measuring a manual alignment mark. When an electronic measurement module (50) is used, carpenter (6) simply uses tool (30) to bring the front plates (26) in contact with a surface of first structure (10) and activates (if not already active) the distance measurement sensor to indicate the distance from an adjacent structure and moves joist hanger along the surface of first structure (10) until the desired distance is achieved. Then the carpenter uses the vertical alignment indicators to vertically align the joist hanger while the alignment-element is associated with the proper alignment point of structure (10). When the proper distance is indicated, and vertical alignment is indicated while the alignment-element is associated with the alignment point, the front plates (26) are secured to first structure (10). Next the second structure is associated with the joist hanger as before and secured in place. This method also allows the carpenter to easily establish a consistent non-zero grade if desired.

Adjustable Tool

(72) As described above, FIG. 4 through FIG. 10 depicts a tool apparatus (30) that is one integral part including the alignment-element (32). Further, alignment-element (32) was configured to be associated with an alignment point such as the bottom edge of structure (10). Such a system works well for a plurality of second structures (14) where such second structures have uniform shape and dimensions. When the second structures are a joist, for example, and such plurality of joists where perhaps machined at different times, the widths and/or heights of such plurality of joists may vary. One of ordinary skill in the art will appreciated that such is a problem when the reference point is the bottom of the first structure (10) and it is the top edges of first structure (10) and second structure (14) that need to be level. Consequently, the next alternative embodiment shows an adjustable tool apparatus (30) defining an adjustable alignment-element (32b).

(73) Attention is now directed to FIG. 11 through FIG. 31 which presents one exemplary embodiment of an adjustable tool apparatus (30) for associating an attachment-element (20) to a first structure (10). As before, tool apparatus (30) comprises a handle-portion (36) and opposing interface-portion (38) wherein said handle-portion (36) defines a handle top end (36a) and an opposing handle bottom end (36b) and wherein said interface-portion (38) defines an interface-top-end (38a) and an opposing interface-bottom-end (38b).

(74) As before, tool apparatus (30) further comprises top-portion (42) and bottom-portion (44) wherein said top-portion (42) mechanically associates handle top end (36a) to interface-top-end (38a) and bottom-portion (44) mechanically associates handle bottom end (36b) to the interface-bottom-end (38b). It should be noted that for the currently preferred embodiment top-portion (42) defines an angular section in contrast to the generally straight top-portion for the previous embodiment. As shown in FIG. 11, a tool-void (40) is defined between the handle-portion, interface-portion, top-portion, and the bottom-portion.

(75) As with the previous embodiments, at least one portion of the adjustable tool defines a portion void and preferably a plurality of portion-voids (35). Such portion-voids reduce the amount of material required to form tool (30) an also reduces the tool's weight and provides provide storage and interface features.

(76) For the adjustable tool apparatus (10) depicted in FIG. 11-FIG. 31, a removable alignment-element (32b) is shown removably mechanically associated with alignment-element receiver (31, FIG. 16) defined by bottom-portion (44) and extends perpendicularly away from the interface-portion (38). Similarly, as best seen in FIG. 23-FIG. 24, interface-portion (38) defines a plurality of alignment-element-receivers (31a), (31b), and (31c) configured for releasably receiving an alignment-element (32b) configured to be releasably associated with any one of said plurality of alignment-element-receivers (31a-31b).

(77) For example, FIG. 23b depicts an alignment-element (32b) associated with one of the alignment-element-receivers in group (31a). One of ordinary skill in the art will appreciated that for the configuration depicted in FIG. 23b, the reference point defined by structure (10) will be first structure top edge (12) instead of first structure bottom edge (13). Thus, attachment-element (20) will be associated with structure (10) referenced to top edge (12) so that any difference in second structure (14) height causes no alignment error.

Adjustable Arm

(78) Referring now more particularly to FIG. 34 through FIG. 36, tool (30) is configured with an Adjustable Arm (70). As before, the currently preferred embodiment of the adjustable tool (30) is configured for associating an attachment-device (such as a joist hanger) with a structure (such as a ledger board) but with the addition of an adjustable arm (70). The handle-portion (36) is associated with the opposing interface-portion (38) as before but with an adjustable arm element adjustably associated with such interface-portion (38) as depicted in FIG. 34. The interface portion defines an integral first alignment-element (32) as best seen in FIG. 10 (and FIG. 34). For one embodiment such alignment-element (32) is removable. Alternatively, for one embodiment, as best seen in FIG. 23, the interface-portion (38) defines a plurality alignment-element-receivers each configured for releasably receiving the removable first alignment-element (32). The adjustable arm element (70) is adjustably associated with the interface-portion (38) and further defines a second alignment-element (78) defined by top element (74). The second alignment-element is configured to use the first structure top edge (12) to define a reference point whereas the first alignment-element (32) is configured to use the first structure bottom edge (13, FIG. 2) to define a reference point (as described above). For some configurations the first alignment-element (32) is removed when the second alignment-element (78) is used.

(79) As best seen in FIGS. 34 and 35, the adjustable arm element (70) comprises a side arm (72) mechanically associated with a top element (74). The top element (74) defines the second alignment-element (78). The side arm (72) is adjustably associated with the interface-portion (38) so that the side arm (72) can be moved up and down the interface-portion (38) as needed. Side arm (72) further defines a plurality of scale elements (76a, 76b, 76c, FIG. 36) referred to collectively as scale elements (76). When the first structure (10) is a ledger board, such ledger board may come in a plurality of widths such as 8 inches (28), 10 inches (210) and 12 inches (212), (depthwidthlength is not import for this discussion). Scale 76a is used for a 28 board, scale 76b is used for a 210 board and scale 76c is used for a 212 board. Such scale elements (76) allow for a fine tuning of the reference point.
