Description




BACKGROUND OF THE INVENTION




1. Technical Field




The present invention relates generally to hand-operated tools, and more particularly to a tool for extracting an elongated object, especially a nail, tack or staple, that is embedded in the surface of a body, such as a wooden board.




2. Background Information




In construction, more labor means higher cost. A small amount of time saved in pulling each spent nail, tack or staple from various surfaces in a building during a remodeling project can mean significant labor savings when the time savings for all of the craftsmen for the duration of the remodeling project are tallied. In short, a better extraction tool allows talented craftsmen to spend their time on more challenging tasks.




Generally, various tools for helping carpenters and other workers remove spent nails or the like from surfaces are known. Unfortunately, nail heads are often partially or wholly broken off when a molding or other surface is removed during remodeling. There are also many new types of nails and staples being manufactured today. Many of these new types of nails have smooth finishes and are more slender than nails used in previous generations. Pneumatic finishing nails, for example, ordinarily have a very small, thin head. Modem nails and staples also vary widely in length and diameter. They can be difficult to remove without bending or snapping them, or splintering or otherwise damaging the wooden and other surfaces in which they are embedded. Practically speaking, nails, tacks, and staples do not often present themselves in an erect fashion for removal from boards and other surfaces. A significant percentage of nails, tacks, and staples to be removed are smashed against the surface, or otherwise bent and/or broken off.




Unfortunately, it is difficult to consistently pull a variety of nail types, as well as tacks and staples, under varying conditions using currently available tools. Some workers attempt to use conventional pliers or channel locks to pull nails through wooden boards, which often causes portions of the nail to break or shear off. Available tools often work only on nails which present a substantially straight and significant shaft segment for a nail puller tool to grasp. When a carpenter has to straighten nails in order to use a nail pulling tool, time is wasted. When he or she has to carry several tools for nail, tack and staple removal, and pause to select which tool to use to remove each nail, time is wasted. This is particularly inconvenient when the worker is in an awkward position on a ladder or on a roof or in a crawl space, for example. Incorrect nail, tack or staple removal can result in damage to the wooden surface, such as gouges or holes. In addition, worker frustration and the high physical demands of construction-related jobs are decreased somewhat when nails and the like can be more easily removed.




Upholstery tacks are particularly bothersome to remove, particularly for the growing number of laymen who do their own upholstering. The spent upholstery tacks, or staples, are often liberally implanted in various odd directions into the wooden backs, seats, etc. of the furniture to be re-upholstered. Wiring staples are also bothersome to remove. They are installed, often every 16 inches, over electrical wires to hold the wires in place on wall studs. An easy to use tool that can speed the removal of these and other types of tacks and staples can decrease the amount of time that must be spent on the job and reduce the number of small injuries incurred while struggling with stubborn staples, etc.




BRIEF SUMMARY OF THE INVENTION




The present invention is a hand tool for extracting an elongated object that is embedded in the surface of a body, the tool comprising:




a) an elongated, movable first handle member;




b) a corresponding second handle member pivotally attached to the first handle member, the second handle member comprising a first jaw member;




c) a floating head portion pivotally attached to the first and second handle members, the floating head portion comprising a second jaw member and an adjacent curved edge; and




d) a lever bar connected at one end to the second handle member and at an opposite end to the floating head portion; and




wherein the extracting tool generally has an open position for placing the jaw members on opposite sides of the elongated object, and a closed position for grasping and pulling the elongated object; and wherein the second jaw member is engaged against the first jaw member when the tool is in the closed position, and disengaged from the first jaw member when the tool is in the open position.




The tool of the present invention presents a unique advantage in that it can aid in quick, safe, clean removal of a wide variety of nails, tacks, or staples, regardless of the position the nail, staple, or tack is in at the time. Damage to the surface, such as splintering and gouging, is minimized because nails, staples, and tacks are more easily and smoothly removed by pulling them through. Crown moldings, baseboards, shelves, paneling, and other surfaces can thus be preserved and reused. The present device does not require a great deal of force to use, and preliminary nail straightening is virtually eliminated, so physical demands are less. Many small injuries, particularly punctures and bruises on the thumb and forefinger, are avoided. Worker job frustration is decreased because spent nails, tacks, staples, and the like can be removed without trouble. The versatile tool of the present invention can grasp and remove short or long, slender or thick nails, tacks or staples, with smooth or rough finishes. This tool is capable of pulling intact or broken-off nails or tacks with broken or small or nonexistent nail heads, so long as some portion of the shaft is visible above the surface. The tool is inexpensive to manufacture, easy to use, and effective in removing quantities of spent nails, staples, tacks, or other elongated objects.

DETAILED DESCRIPTION OF THE INVENTION




In the following description, like reference characters designate like or corresponding parts throughout the several views. Also, in the following description, it is to be understood that such terms as “front,” “rear,” and the like are words of convenience and are not to be construed as limiting terms. Referring in more detail to the drawings, the invention will now be described.




Referring to

FIGS. 1 and 2

, an extracting tool constructed in accordance with the present invention is generally shown at


10


. A preferred embodiment of the extraction tool


10


is shown from the front in

FIG. 1

, and from the rear in FIG.


2


. Generally, the extraction tool


10


has an elongated, movable handle section


11


attached to a head portion


12


. The head section


12


is at the lower end of the tool when the tool is held by a user in an upright position in readiness for extraction of an elongated object, especially a nail or staple, from a surface in which it is embedded, especially a wooden board. The extracting tool


10


is preferably substantially made of good quality tool steel, or any other suitable, sturdy material.




Referring to

FIGS. 1-4

, the nail extraction tool


10


generally has four parts, with four pivot points: 1) an elongated, movable first handle member


13


; 2) an elongated second handle member


14


pivotally attached to the first handle member


13


; 3) a floating head portion


15


pivotally attached to the first and second handle members


13


,


14


; and 4) a lever bar


16


, which connects the second handle member


14


and the floating head portion


15


. The tool


10


generally has two positions: open, as shown in

FIGS. 1 and 4

; and closed, as shown in

FIGS. 2 and 3

.




The removal tool of the present invention is for pulling an elongated object, particularly a nail, tack, or staple (a bent elongated object), which is embedded in the surface of a body. A visible portion of the elongated object, such as the bottom part of a nail shaft (body) or central part of a staple, must extend at least slightly beyond the surface in order for the user to see it and the tool to grasp it. In use, the tool is placed in an open position as shown in

FIG. 1

by pulling the upper, free ends of the handle members


13


,


14


away from each other. When the tool


10


is covering the protruding portion of the nail, staple, tack, or other object, the handle members are preferably approximately perpendicular to the surface. By “covering the nail” is meant that the two jaw members are in place on either side of the nail shaft, staple, or other object. The tool


10


is placed over the projecting portion of the elongated object, with the first jaw member


17


on one side of the projecting portion of the object and the second jaw member


18


on the other side. Once the tool


10


is resting on the surface, ordinarily a wooden board, the upper, free end portions of the handle members


13


,


14


are squeezed towards one another, which closes the jaw members over the object. This is accomplished with one hand.




As shown in a preferred embodiment in

FIGS. 1-6

, the second handle member


14


comprises a serrated first jaw member


17


along one end portion, and the floating head portion


15


comprises a corresponding serrated second jaw member


18


along one of its sides. The tool's jaw members


17


,


18


are parallel to one another. Preferably, one or both, most preferably both, jaws are serrated. The serrated teeth allow a good grip on the shaft of the embedded object. As shown in

FIGS. 1-4

, the serrated gripping teeth, are most preferably oriented in an upward direction (i.e., leaning toward the main pivot pin), and oppose one another, in order to facilitate gripping of the object being extracted. The uppermost, or first, set of teeth in each jaw member preferably oppose each other, so that the tool


10


contacts the embedded object as close to the surface (substrate) as possible. Other gripping means could be employed in place of serrated teeth.




As illustrated by the figures, the floating head portion


15


has an upper edge


19


that is curved, so that the tool


10


can rock back on the curved edge


19


during extraction of the nail, tack, staple, or the like. By “floating” head portion is meant that this portion of the tool is movable and is not connected to the rest of the tool except by pivot pins. The curved edge


19


on the floating head portion creates a lifting force, with minimum resistance to the user. The curved edge


19


of the floating head portion is preferably flattened, so that the flat edge is in contact with the surface when the closed tool


10


rocks back.




The width of the curved edge


19


can vary, although it is preferably between about ¾ and 1 ¼ centimeters, most preferably approximately ⅜ inch, in width. This width helps to prevent damage to the surface (ordinarily wood) during extraction of the nail. A thin layer of rubber or other cushioning material, or a protective coating, can be applied along the curved edge


19


to further cushion the curved edge. The remainder of the floating head portion may be at a slightly lower level than the curved edge


19


and the jaw member


18


, as shown in

FIGS. 5 and 6

. As a result, the ends of the second and third pivot pins


23


,


25


, which project through the floating head portion


15


, are not as likely to scratch the user. This allows the tool


10


to have a flatter front and rear appearance, and facilitates shipping of these tools.




Referring to

FIGS. 1-6

, the third, lower side


20


of the floating head portion


15


is preferably slightly curved so that it fits against the curve in the second handle member


14


when the tool is in a closed position. However, the floating head portion can have various shapes and need not fit against the second handle member, as shown in FIG.


7


. The shape of the fourth side


21


of the floating head portion


15


, which is approximately opposite to the first side, basically does not affect the function of the floating head portion. In the alternate embodiment shown in

FIG. 7

, the third side


20


of the floating head portion does not fit against the second handle member, and the fourth side


21


is more rounded.




As shown in

FIGS. 1-6

, each tool


10


comprises four pivot points in two sets. The first set of pivot pins are inserted along an upper end portion of the first handle member


13


. A main pivot pin


22


pivotally connects the first handle member


13


to the second handle member


14


at the base of the head section


12


. A second pivot pin


23


pivotally connects the end of the first handle member


13


and a forward section of the floating head portion


15


next to the second jaw member


18


. At the main pivot pin


22


, the curved first handle member


13


crosses perpendicularly over the curved second handle member


14


, generally forming an X-shape. The second set of pivot pins is inserted at opposite ends of the lever bar


16


. A third pivot pin


24


connects the lower end of the lever bar


16


to the second handle member


14


, and a fourth pivot pin


25


pivotally connects an upper end of the lever bar


16


to a rear section of the floating head portion


15


. Each pivot pin can alternatively be a rivet or screw at a similar pivot point. The lever bar


16


maintains the parallel relationship between the jaw members


17


,


18


, and links the handle members to each other so that the second handle member contributes to the force required to extract the nail. The lever bar


16


is preferably on the front of the tool, as shown in the figures, but it could alternatively be located at the rear of the tool. wherein the first handle member has a curved end portion, the end of which is pivotally attached to the floating head portion.




Thus, 1) the main pivot pin


22


passes through corresponding holes in the first handle member


13


and the second handle member


14


, 2) the second pivot pin


23


passes through corresponding holes in the end of the first handle member


13


and a forward section of the floating head portion


15


, 3) the third pivot pin


24


connects through corresponding holes in the second handle member


14


and a lower end of the lever bar


16


, and 4) the fourth pivot pin


25


passes through corresponding holes in an upper end of the lever bar


16


and a rear section of the floating head portion


15


. The distance between the main pivot pin


22


and the second pivot pin


23


, and between the third pivot pin


24


and the fourth pivot pin


25


, are substantially equal to one another. The distance between the main pivot pin


22


and the third pivot pin


24


, and between the second and fourth pivot pins


23


,


25


, are substantially equal to one another. A parallelogram is thus formed. The parallelogram shape shifts as the tool


10


is brought from an open position to a closed position and back again. Preferably, the main pivot pin


22


is a screw, and the second, third, and fourth pivot pins


23


-


25


are rivets. The jaw members maintain a parallel relationship to one another in both the open and closed positions.




In the alternate embodiment shown in

FIG. 2



a


, a pivotable second lever bar


32


connects the main pivot pin


22


and the second pivot pin


23


, and/or a pivotable third lever bar


33


connects the third pivot pin


24


and the fourth pivot pin


25


for added strength.




The tool of the present invention employs a compound lever action. The lever bar


16


is pivoting further out on the floating head portion


15


and is anchored to the second handle member


14


, which has the opposite jaw member


17


. Without meaning to be bound by theory, it is believed that two important things happen because of this compound lever action: a) the jaw members


17


,


18


stay in a parallel relationship, which maintains as many teeth as possible in contact with the object for a slip-free grip; and b) the curved edge


19


is attached to the opposing jaw member by the lever bar


16


. Once the rolling or lifting of the nail, staple, or other elongated object begins, the resistance force is passed to the jaw member opposite to the curved edge, which causes a self-actuating grip. Net: once the extraction is initiated, the handle members no longer need to be squeezed. At that point, only a prying action is required to complete the extraction.




This tool


10


is for removing damaged or intact nails or tacks, staples inserted with a pneumatic gun, or the like, by gripping the exposed part of the nail or staple once the board is removed from the wall. The tool of the present invention can grasp and remove slender or thick nails, tacks or staples with smooth or rough finishes. It can be used on nails manufactured without heads, and nails with heads that are broken or sheared off. This tool


10


is capable of pulling long or short, intact or broken-off nails, staples, or tacks, regardless of whether they were driven into the surface by a hammer or by pneumatic means. This tool


10


works particularly well on wiring staples, fencing staples, roofing tacks, and upholstery tacks. The tool can also be used for other common tasks, like holding a bolt, or straightening a metal wire.




This tool is preferably for use on finishing nails of any length or width, bent or straight, especially pneumatic finishing nails. Relatively new pneumatic finishing nails are particularly difficult to remove from surfaces because they have a very smooth finish and are so slender that they cannot easily be backed out without bending them. Efforts to pull them out of wooden surfaces using conventional tools often results in splintering of the surface or in the nails snapping off. The nail removal tool of the present invention grabs these pneumatic finishing nails and ordinarily pulls them cleanly through and out of the surface.




The nails, etc. to be removed may be embedded in wooden baseboards, moldings, shelving, paneling, hardwood floors, etc. The tool of the present invention is particularly useful for remodeling projects. Workmen who will be pulling apart wooden elements of a residence or business and then replacing them may also find this tool helpful. For example, exterminators and burglar alarm installers often must pull up baseboards, etc. to do their work. They can use this tool for removing nails prior to reattaching the baseboards and other surfaces. This tool is useful wherever the removal and spent nails from wooden or wood-like surfaces is particularly important. It is particularly useful for remodeling projects in historic homes, where preservation of existing crown moldings, baseboards, etc. is of paramount importance.




Referring to

FIGS. 7 and 8

, alternate embodiments of the extracting tool


10


include a spring device


26


between the first and second handle members


13


,


14


under the head section


12


. With the spring device


26


between the handle members, it is not necessary to pull part the handle members before beginning the extraction. This embodiment may be more comfortable for a user with small hands to use. The spring device


26


allows the handle members to spring back into the open position once the handle members are released.




In the embodiment illustrated in

FIG. 7

, the spring device


26


comprises two bent arms


27


, with a spring


28


between the two arms. An upper end of each arm


27


attaches through a hole in one of the handle members


13


,


14


. The lower ends of the two arms


27


continue into the spring


28


formation. One of the arms


27


is positioned against the first handle member


13


, and the other is positioned against the second handle member


14


. The spring device may alternately include an expansion spring wrapped around two arms projecting from the inside of each handle member. The upper, free end portions of the handle members


13


,


14


may have textured rubber-like covers or grips


29


for comfort.




In the alternate embodiment illustrated in

FIGS. 8 and 9

, only an elongated top row of opposing teeth remains. This first set of teeth


30


on the opposite jaw members


17


,


18


oppose one another. This allows the tool a grasp of small, fine objects. The jaw members curve inwardly below the first set of teeth, and do not include additional teeth. In this preferred embodiment, the first set of teeth


30


on each jaw member are similarly forked, so they form a diamond shaped orifice


31


when the tool


10


is in a closed position. The orifice


31


is smaller than the head of a conventional nail or tack; thus, the orifice


31


, as well as the inward curve of the jaw members, allow the head of a tack


32


or nail to be held inside the tool


10


, as shown in

FIG. 9

, without slipping through the tool


10


. This provides better leverage when the nail or tack is being extracted. Since the sharp ends of the opposing teeth


30


contact one another, the orifice


31


minimizes the chances that the opposing teeth


30


will shear off the nail or tack. This embodiment works particularly well for upholstery tacks


32


. If the tack


32


has a head with a diameter that fits between the inward curves of the jaw members, as shown in

FIG. 9

, a lifting motion is also imparted when the tool


10


grips the tack


32


. The pointed, opposing first teeth


30


and the inward curve of the jaw members are also helpful in extracting pneumatically driven, industrial staples, which are often embedded deeply in a surface. Generally, the pointed opposing teeth


30


fit under each end of the crown of the implanted staple. This embodiment is particularly useful where there is a single point of contact with the embedded object.




As shown in

FIG. 9

, the handle members


13


,


14


are each bowed slightly outwardly in the center, and preferably also each crooked at the base, for a better grip by the user.




In a preferred embodiment: a) the tool


10


is between about ten and 12 inches in length and about two and three inches wide; b) the jaw members


17


,


18


are between about ½ inch and 1 ½ inches in length, and about ¼ and ½ inch in width; c) the curved edge


19


is between about two and three inches in length and about the same width as the jaw members; d) the lever bar


17


is between about one and two inches in length; and e) the floating head portion


15


is between about one and three inches in length and width. The long handle members


13


,


14


are useful for gaining leverage during the extraction process.




In the alternate embodiment shown in

FIGS. 10 and 11

, an upper portion of the first handle member


13


splits just before the main pivot pin


22


. These split first handle member portions straddle the second handle member


14


and the floating head portion


15


, for added tool strength and case of manufacture. The split first handle member portions end at, and arc both pinned by, the second pivot pin


23


. The tool's mechanics are otherwise as described above.




This invention is a versatile, inexpensive, hand operated tool for removing nails, tacks, staples, or other elongated objects from surfaces, such as moldings, baseboards, and shelves, without unduly damaging the surface. With the present device, the worker's initial attempts at removal of nails, tacks, and staples are successful a high percentage of the time. It is believed that this is more true of the present tool than of other currently available devices.




Also included within the present invention is a method for extracting an elongated object through a body made of wood or a wood substitute and having a surface. The method includes the steps of:




a) engaging a portion of the object by a tool;




b) operating the tool such that the tool grips the object and exerts twisting and pulling forces on the object in a direction at an acute angle to the body surface;




c) rocking the tool back on a curved, flattened edge of the tool in a direction away from the wooden surface, so as to disengage the object from the surface; and




d) disengaging the object from the tool.




From the foregoing it can be realized that the described tool of the present invention may be easily and conveniently utilized for extracting elongated objects from surfaces in which they are embedded. While preferred embodiments of the invention have been described using specific terms, this description is for illustrative purposes only. It will be apparent to those of ordinary skill in the art that various modifications may be made without departing from the spirit or scope of the invention, and that such modifications are intended to be within the scope of the present invention.
