DETAILED DESCRIPTION OF THE APPLICATION

Turning now to a more detailed description of the present invention, there is illustrated in FIGS. 1 to 3 embodiments of the hand tool of the present invention. The illustrated embodiments explain and illustrate the construction, context, and applicability of the present invention to one of skill in the art of construction, pipe fitting, and the like.

The specific types of construction or other tasks that are facilitated by the use of the present invention in general will not be described in extensive detail inasmuch as such details are known to those skilled in the art. Moreover, the hand tool will be useful for tasks and jobs that have yet to be contemplated. The hand tool is adaptable for operation within a variety of construction, plumbing, engineering or other fields.

Turning to FIG. 1, there is illustrated a hand tool 10 of a roughly hexagonal shape. The hand tool of the present invention can be formed from any type of suitable material, including aluminum, iron, steel, plastic, and the like. In one embodiment, the hand tool provides a unitary, substantially planar body made of metal.

The tool's shape roughly or substantially defines a hexagon. As such, there are six exterior sides to tool 10. A first side 12 meets a second side 14 and a third sides 16 at 135-degree interior angles at the respective first and second ends of first side 12. Second side 14 and third side 16 join first side 12 to a fourth side 18 and a fifth side 20. The intersections of second side 14 to fourth side 18 and third side 16 to fifth side 20 form 90-degree internal angles. A sixth side 22 connects fourth side 18 and fifth side 20 to define a substantially hexagonal perimeter. However, while sixth side 22 is linear like the remaining sides of the substantially hexagonal tool, the sixth side is recessed from the perimeter of tool. Therefore, tool 10 is substantially hexagonal with sixth side 22 recessed from the perimeter of tool defined by the remaining sides of the otherwise hexagonal tool.

As illustrated, each side of the tool is parallel to the opposing side. Therefore, first side 12 is parallel to recessed sixth side 22, second side 14 is parallel to fifth side 20, and fourth side 18 is parallel to third side 16. The opposing sides are also of substantially equal lengths.

The dimensions of tool 10 dictate that each 90-degree internal angle, which are located at the intersection of the second to fourth sides and third to fifth sides, is directly opposite the corresponding 90-degree angle. As such, a line bisecting either of the two angles would bisect the opposite angle as well.

The first, second, third, fourth and fifth sides define a first thickness D. The ‘thickness’ of the planar body, as used herein, is the dimension of the body taken perpendicular to the plane defined by the longitudinal axis of the tool. At least one channel or slot 24 is formed along part or all of the length of the respective sides. The at least one channel/slot is, therefore, on the perimeter of tool 10. Planar or geometric tools, such as square edges, rulers, straight edges, or the like, can be inserted into the channels. Fasteners, such as thumbscrews, pass through the tool body to selectively engage tools placed in the slot(s) (as further described below). The attachable tools are held in place by the fasteners. In one embodiment, a first slot 24 wraps around the perimeter of the tool through the length of fourth side 18, second side 14, and a portion of first side 12. A second slot 24′ wraps around the perimeter of the tool through the length of fifth side 20, third side 16, and a portion of first side 12. The first and second slots are not connected. In addition, it is envisioned that tool 10 can include just one of slots 24, 24′ or that a single slot 24 can mm the full length of each of the first through fifth sides.

With references to FIGS. 1 and 2, and as described above, sixth side 22 is recessed relative to the substantially hexagonal shape otherwise defined by the first through fifth sides. In one embodiment, sixth side 22 is also of a reduced thickness d′ relative to the thickness of the planar tool body defined by the first through five sides. The recessed structure and reduced thickness d′ of sixth side 22 provides a means to better grip or handle tool 10. A user can then use the dimensions of the tool, with or without selectively attached geometric tools, to measure or place structural members, such as pipes. As best seen in FIG. 2, the addition of geometric tools would otherwise limit the ability to hold the tool by sixth side 22 if sixth side 22 were not recessed from the perimeter otherwise defined by the first through fifth sides.

A relatively thin, planar bridge 30 connects to the interior of each side of the hand tool (i.e., the first through sixth sides). In a preferred embodiment, the thickness of bridge 30 is substantially the same as or identical to thickness d′ as provided by sixth side 22 of hand tool 10. Optional openings 32, 32′ are included in bridge 30 so that a user can better grasp and manipulate tool 10 via relatively thin bridge 30.

As briefly described above, and as illustrated in FIG. 2, one or more geometric or planar tools 40 can be inserted into the at least one slot found along the perimeter of tool 10. The ability to add straightedges, rulers, squares, and the like creates a number of mechanisms that the tool user can customize to meet the demands of a particular task. Therefore, the tool is adaptable to wide variety of uses within the fields of pipefitting, general construction, and the like. In fact, a huge variety of measuring options are available. For instance, the attached tools 40 can be used to properly space structural elements (stair stringers, cross members, or the like). Hand tool 10 could also be used for drafting purposes.

Tools 40 are selectively secured to tool 10 by a number of fasteners 42. Fasteners 42 may be screws, thumbscrews, or other known fasteners that are operable to apply pressure to tools 40 in slots 24, 24′. In one embodiment, fasteners 42 are thumbscrews inserted into threaded apertures located in tool 10 where the threaded apertures are perpendicular to the plane of the at least one tool slot. The axis of each aperture intersects with the corresponding slot. In use, the user threads thumbscrew 42 into the aperture until the thumbscrew engages tool 40. Pressure applied by the thumbscrew holds the tool in place. Of course, it is envisioned that tool 10 may have one continuous slot, one truncated slot 24, or a plurality of slots 24, 24′, as illustrated in FIGS. 1-3.

Additional depth adjustment means 44 or tool engaging means 44 are provided via a plurality of thumbscrews, screws, or other type fastener. These fasteners are in-plane with the channel 24 or channel 24′. These fasteners/thumbscrews provide a shaft with a notched or semi-spherical end to better hold a tool within the channel. As a depth adjustment mechanism, fasteners 44 are inserted through an aperture wherein the aperture is in-plane with slot 24 or slots 24, 24′. Users access the depth adjustment mechanism 44 or tool engaging means 44 via openings 32 and/or 32′. In one embodiment, the depth adjustment mechanism 44 is a thumbscrew. Threading the thumbscrew into the aperture engages the edge of a tool 40 to either selectively hold the tool in place or to adjust the depth of the tool within the respective slot. In another embodiment, mechanism 44 is a threaded post with a nut operable to move the post into and out of the slot. As the post engages a tool 40, the depth of the tool within the respective slot is adjusted.

With reference now to FIG. 3, as envisioned for one embodiment of the present invention, first side 12 includes embedded magnets 50. Magnets 50 are operable to mount tool 10 to a metal member, such as a pipe.

In another embodiment, a level 60 is also embedded or placed within the body of tool 10. The level indicates a level condition in at least one plane. In another embodiment, the level indicates a level condition in at least three planes via known indicating mechanism (e.g., a bubble in a fluid filled tube).

Overall, the substantially hexagonal shape of hand tool 10 and the ability to affix various planar tools along up to five sides of the tool creates an extremely versatile and useful tool in a variety of construction fields. The integrated level provides a level indicator in three planes so that the hand tool can be leveled when rotated to a number of positions, including the ability to create 45-degree connections. The integrated magnets are useful for holding the hand tool in place where desired. Additional magnets might be included along the exterior of any of the sides.

Although the present invention has been described in terms of one or more preferred embodiments, it will be understood that numerous variations and modifications may be made without departing from the invention. Thus, for example, the material or ornamental design of the hand tool can be varied without leaving the scope of the disclosed invention. Additional embodiments and uses of the hand tool will become apparent to one skilled in the art. Thus, it is to be understood that the invention may be practiced otherwise than as specifically described above.
