Description
- This disclosure relates to the field of alignment devices. More particularly, this disclosure relates to apparatus for aiding in the construction of a structure by facilitating the alignment of sub-structures during construction.
- Construction technology has evolved for thousands of years and has become scientifically advanced with the use of computing technology and the use of advanced materials to build new structures. However, certain aspects of constructing structures have remained relatively unchanged over the years. For example, the structural integrity of a structure depends in large part on whether various sub-structures have been attached together in a desired manner. The ability to attach sub-structures with precision requires a reliance on basic geometric principles such as the use of straight lines.
- A number of devices have been used to help a person building a structure to keep a part of the structure aligned in a straight line. One example is the use of string attached at one or both ends substantially along the part of a structure to be constructed in a straight line. Such strings are often attached to sticks anchored in the ground or along the structure being built. Strings are also attached to other devices designed for fitting over specifically sized sub-structures at a corner or end of the structure being built. However, these devices for attaching string to structures lack a combination of flexibility of use on a variety of sub-structures, integrity to remain substantially in place without physically impacting the underlying structure being built, and accuracy to better ensure proper alignment of sub-structures during construction.
- What is needed, therefore, is an alignment device that may be used on a variety of different sized sub-structures at various locations along a structure being built for gaining an accurate alignment of sub-structures during construction but having minimal, if any, physical impact on the underlying structure.
- The above and other needs are met by embodiments of an apparatus for aligning substructures to facilitate the construction of a structure. In one embodiment, the apparatus includes an elongate bar including a proximal end and a distal end; a movable member including a first portion and a second portion, the movable member being movable along the bar between the proximal end and the distal end of the bar; an end member adjacent the bar, the end member including a first extension and a second extension, the first extension including a groove for attaching a string to the apparatus, the second extension including a groove for positioning a string substantially adjacent to any substructure that the apparatus may be placed on, the second extension being located substantially opposite the second portion of the movable member; and an obstruction located near the distal end of the bar for preventing the movable member from moving off of the bar.
- In a preferred embodiment, the first extension of the apparatus includes a plurality of grooves for attaching a string to the apparatus. The cross-sectional structure of the bar preferably is in the form of a polygonal shape. In another preferred embodiment, the apparatus is made from metal or a metal alloy. Optionally, the movable member is angled toward the proximal end of the bar.
- A related embodiment includes an apparatus for aligning substructures to facilitate the construction of a structure in which the apparatus includes an elongate bar including a proximal end and a distal end wherein the cross-sectional structure of the bar includes a polygonal shape; a movable member including a first portion and a second portion, the movable member being movable along the bar between the proximal end and the distal end of the bar wherein the movable member is movable by sliding motion along the bar; an end member adjacent the bar, the end member including a first extension and a second extension, the first extension including a groove for attaching a string to the apparatus, the second extension including a groove for positioning a string substantially adjacent to any substructure that the apparatus may be placed on, the second extension being located substantially opposite the second portion of the movable member; and an obstruction located near the distal end of the bar for preventing the movable member from moving off of the bar. Preferably, the first extension of the apparatus includes a plurality of grooves for attaching a string to the apparatus. The cross-sectional structure of the bar preferably is in the form of a polygonal shape. The apparatus is preferably made from metal or a metal alloy. Optionally, the movable member is angled toward the proximal end of the bar.
- In another aspect, embodiments of the invention provide a method for aligning substructures to facilitate the construction of a structure using a alignment apparatus, the alignment apparatus including an elongate bar including a proximal end and a distal end; a movable member including a first portion and a second portion, the movable member being movable along the bar between the proximal end and the distal end of the bar; an end member adjacent the bar, the end member including a first extension and a second extension, the first extension including a groove for attaching a string to the apparatus, the second extension including a groove for positioning a string substantially adjacent to any substructure that the apparatus may be placed on, the second extension being located substantially opposite the second portion of the movable member; and an obstruction located near the distal end of the bar for preventing the movable member from moving off of the bar. The method includes the steps of (a) placing the alignment apparatus on a substructure such that the second portion of the movable member and the second extension of the end member are located on opposite sides of the substructure; (b) wrapping a string around the first extension of the end member such that the string is inserted into the groove located along the first extension; (c) wrapping the string under the bar along the groove in the second extension; and (d) pulling the remaining string from the groove in the second extension under the bar in order to set a desired alignment guideline along an unfinished structure.
- In a related embodiment, step (a) further includes the step of moving the movable member closer to the proximal end of the alignment apparatus until both the second portion of the movable member and the second extension of the end member are in contact with the sub-structure.
- On advantage of various embodiments of the invention is that the apparatus may be attached at various locations along a structure that is under construction. It is not necessary that the apparatus be attached on a corner of the structure.
- Another advantage of various embodiments of the invention is that the apparatus may fit a broad range of structures that are sized considerably different from one another. This is made possible by moving the movable member to fit various sized substructures.
- Yet another advantage of various embodiments of the invention is that the apparatus has little or no impact on a substructure it is placed on. More specifically, there is no need to insert any part of the apparatus into a substructure in order for the apparatus to hold steady during use.

Additionally, thefirst extension 26 and thesecond extension 28 are preferably oriented approximately 180 degrees from each other.FIG. 5 shows a view of thefirst side 36 ofapparatus 10 in which a string has been attached to thegroove 30 of thefirst extension 26 and has been wound through thegroove 32 located along thesecond extension 28. -
FIG. 6 shows an end view of thedistal end 16 of thebar 12. The embodiment shown inFIG. 6 includes thebar 12 having a rectangular cross section. However, in other embodiments, the cross section of thebar 12 may be another polygon such as, for example, a square, a hexagon, or an octagon. The cross section of thebar 12 may also be in the shape of a circle, an oval, or a combination of curved and straight edges. -
FIG. 7 shows a close up view of thedistal end 16 of thebar 12 along thesecond side 40 of theapparatus 10.FIG. 7 revealsobstruction 34. Theobstruction 34 shown in the embodiment inFIG. 7 was formed by creating anindentation 44 along thesecond side 40 of theapparatus 10, thereby slightly raising aperiphery 46 around theindentation 44, whereby the raisedperiphery 46 acts as theobstruction 34. In other embodiments,obstruction 34 may include, for example, a projection attached at thedistal end 16 of thebar 12. In yet another embodiment, theobstruction 34 may be built into the structure of thebar 12 such that the thickness of thebar 12 increases toward thedistal end 16, thereby preventing themovable member 18 from falling off of thebar 12. -
FIG. 8 shows theapparatus 10 along afirst substructure 48 such that thesecond side 40 of theapparatus 10 is facing a person viewing the figure. Themovable member 18 has been moved toward theproximal end 14 of thebar 12 such that both thesecond portion 24 of themovable member 18 and thesecond extension 28 of theend member 20 substantially are in contact with and straddle thefirst substructure 48. Astring 50 has been attached to thegroove 30 along thefirst extension 26 and thestring 50 has been placed throughgroove 32 along thesecond extension 28 such that thestring 50 appears to exit the page toward a person viewing the figure. By pulling thestring 50 in a direction normal to the page, theproximal end 14 of thebar 12 slightly rotates in the direction of the pulledstring 50, locking theapparatus 10 along thefirst substructure 48. Thestring 50 can then be tied off or attached to another device so that thestring 50 may be used to align other substructures as such substructures are added next to thefirst substructure 48.FIG. 9 shows a perspective view of theapparatus 10 after thestring 50 has been pulled and theapparatus 10 has been locked into position. - The
apparatus 10 and other related embodiments may be used to help align substructures such as brick, stone, cement block, wood, and virtually any type of building substructure that requires proper alignment with other substructures. For example, if a brick wall is being constructed, theapparatus 10 may be placed on a brick that has already been attached to the structure, and a string can be attached to the apparatus and vectored in such a way as to help align and lay the remaining bricks in a particular row to form the wall. Theapparatus 10 and other related embodiments may also be used, for example, at the top of a vertical beam of wood that has been attached to a structure. A string can be attached to theapparatus 10 and vectored in such a way as to help align the attachment of other beams of wood to the structure. The term “string” as used in concert with theapparatus 10 is defined broadly herein and includes, but is not limited to, cord, elongate fibers, wire, twine, thread, tape, or any similar material, natural or synthetic. - The length of the
bar 12 preferably ranges from about 2 centimeters to about 40 centimeters, and more preferably ranges from about 20 centimeters to about 25 centimeters. However, depending on the size of the substructure and/or the available work space around a structure, the desiredbar 12 length may vary considerably. For example, in some situations, it may desirable for thebar 12 to be considerably shorter if an immovable object is close or adjacent to a substructure that the apparatus is to be attached to. In the example shown inFIG. 11 , if thebar 12 were to extend beyond the width of a substructure 52 (shown as a common brick with multiple apertures 54), it would collide with awall 56, thereby preventing thesecond extension 28 from engaging substantially adjacent to thesubstructure 52.FIG. 11 also demonstrates how theapparatus 10 may be attached along various features of a substructure such as theapertures 54. - The invention described herein also includes a method for aligning substructures to facilitate the construction of a structure using
alignment apparatus 10 or a related embodiment ofapparatus 10. One embodiment of such method includes a step of placing the alignment apparatus on a substructure such that thesecond portion 24 of themovable member 18 and thesecond extension 28 of theend member 20 are located on opposing surfaces of the substructure (i.e., they straddle the substructure or a portion of the substructure). The method also includes a step of wrapping a string around thefirst extension 26 of theend member 20 such that the string is inserted into thegroove 30 located along thefirst extension 26. The method further includes a step of wrapping the string under thebar 12 along thegroove 32 in thesecond extension 28. The method also includes a step of pulling the remaining string from thegroove 32 in thesecond extension 28 under thebar 12 in order to set a desired alignment guideline of string along an unfinished structure. In a related embodiment, the method further includes the step of moving themovable member 18 closer to theproximal end 14 of theapparatus 10 until both thesecond portion 24 of themovable member 18 and thesecond extension 28 of theend member 20 are in contact with the substructure. - The foregoing description of preferred embodiments for this invention has been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments are chosen and described in an effort to provide the best illustrations of the principles of the invention and its practical application, and to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally, and equitably entitled.
