Description
- This application claims the benefit of U.S. Provisional Patent Application 60/451,359 entitled “Marking Tape Measure” by Gary Pritchard filed Feb. 27, 2003, the entire content of which is hereby incorporated by reference herein for all it discloses and teaches.
- 1. Field of the Invention
- The present invention pertains to measuring devices and specifically to measuring devices capable of making markings.
- 2. Description of the Background
- Framers and construction workers typically have to measure and mark boards and panels during the layout and construction of buildings. Typically, the markings for building studs may occur every sixteen or twenty-four inches. The markings are routinely laid out by extending a tape measure and marking at periodic intervals with a pencil. The task of marking boards and panels is time consuming, as it requires traversing the entire length of a board to make the required marks.
- For example, in the case where the top of an unfinished wall is to be marked, the framer may have to move a ladder every three or four feet along the wall in order to make the required layout marks to attach roofing trusses or the like. Every few feet, the framer may have to set up a ladder, climb the ladder, make the few marks that are within arm's reach, descend the ladder, move the ladder, and repeat the process.
- It would therefore be advantageous to provide a system and method for creating markings on surfaces, such as boards, panels, or walls at specific intervals in a fast and efficient manner. It would further be advantageous if the system and method were compact, portable, and easy to use in difficult places.
- The present invention overcomes the disadvantages and limitations of the prior art by providing a system and method for placing marks on surfaces including boards, panels, or walls in specific intervals in a single operation. A tape measure and chalk line dispenser allows the simultaneous extension of a measuring tape and chalk line. The measuring tape has a plurality of holes disposed along the tape at the specific intervals for marking. The chalk line is disposed above the tape and is tightened and snapped to create chalk marks through the holes and onto the board or panel. The tape and chalk line may then be rewound.
- The tape may have a series of offset holes near the end of the tape that may allow a carpenter to offset the tape and thus the markings by a specific interval. Such offsets may be helpful in certain situations.
- An embodiment of the present invention comprises a device for making at least one mark comprising: a length of tape having at least one hole disposed along the length at a predetermined location; a line disposed along the length such that at least a portion of the line spans the at least one hole; and a marking medium attached to the line.
- Another embodiment of the present invention comprises a device for marking a plurality of marks comprising: means for masking having a plurality of holes disposed along the length of the means for masking at predetermined intervals; and means for dispensing a marking medium disposed along the length of the means for masking and further positioned such that at least a portion of the marking medium passes through the plurality of the holes.
- Yet another embodiment of the present invention comprises a method for making at least one mark on a surface comprising: extending a tape having at least one hole over the surface; spanning the at least one hole with a marking line having a marking medium; withdrawing the marking line from the tape; allowing the marking line to snap onto the tape such that at least some of the marking medium passes through the at least one hole onto the surface.
- The advantages of the present invention are that markings at specific intervals may be made with one motion. Further, the markings may be made from one end of the board without requiring traversing the length of the board to make a mark at every interval.

FIG. 1 illustrates a cut away side view of anembodiment 100 of a marking apparatus. Thebody 102 contains atape spool 104 and achalk line spool 106. As thefree end tip 108 is pulled away from thebody 102, thetape 110 andchalk line 112 are extended with thechalk line 112 being located over or spanning thetape 110. Thetape 110 has a series of markingholes 114 at predetermined intervals. Thetape 110 andchalk line 112 can be simultaneously retracted into thebody 102 by therewind crank 116. Thechalk line 112 travels through holes instanchions tensioner 112. - In operation, one places the
tip 108 of the device over the edge of a surface to be marked, then extends thetape 110 andchalk line 112 simultaneously along the length to be marked. When the tape in the markingapparatus 100 is extended over the length to be marked, thebody 102 may be placed on top of the surface such that thelower arm 124 of thetensioner 112 is pressed against the surface. Thetensioner 112 forces thechalk line 112 against the tape with thetensioning arm 126. The exposedchalk line 112 is stretched betweenstanchions chalk line 112 is lifted and quickly released against thetape 110 with the other hand, allowing the chalk line to return to its normal position in a process known as ‘snapping the line.’ The chalk dust that is supported on thechalk line 112 transfers through themarking holes 114 and make marks on the board at those intervals. - The
tape 110 may be a standard metal measuring tape that has markings typical to commercially available measuring tapes. Thetape 110 may be constructed of steel or other metal, or may be constructed of plastic or other suitable material. - The marking
holes 114 may be placed at periodic intervals that may be useful to those of the building trades. For example, it is common to mark studs and other building components on sixteen or twenty four inch intervals. Thus, the markingholes 114 may be placed at those intervals. In addition, it is often necessary to offset those intervals by a standard amount, such as one half of the width of a stud. Additional offset holes may be provided near thetip 108 to offset themarking holes 114. A nail may be placed in the board and one of the offset holes may be placed over the nail to offset the markings a particular distance. For example, an offset of three-quarters of an inch may be desirable for laying out stud placement. A nail may be placed in the end of the board and an offset hole that is three-quarters of an inch from thetip 108 may be placed over the nail. Thus, for the entire length of the tape, all of the markings can be offset by three quarters of an inch. Other offsets may be accomplished by providing offset holes at predetermined locations along the tape. In another embodiment, thetape 110 may have a series of offset holes through which a nail may be inserted. The nail may then be placed over the edge of a board to offset the markings made by theembodiment 100. In still other embodiments, thetip 108 may be movable such that it may be adjusted to different positions along the axis of thetape 110 in order to offset the marks made by theembodiment 100. - The
chalk line 112 may be a common string that is stored on achalk line spool 106. Thechalk line spool 106 may be enclosed by a chalk compartment in which chalk is stored and by which chalk may become entrained by the string. In other embodiments, the string may be replaced by a woven band with a width greater than its thickness that may be able to produce marks wider than would be possible with a string. - The marking holes 114 may be small circular holes or may be a specially shaped hole that may produce a specially shaped mark. Such shapes may include numerical shapes that may mark the location with a numerical designation. In other embodiments, the marking
holes 114 may include a mark for the edge of a stud or other building member and a second mark or designation for the side to which the stud is to be placed. It is common for a carpenter to mark a location with a line or crow's foot mark and then place an ‘X’ to designate the appropriate side of the line for the stud. Such marks may be placed by an embodiment of the present invention having an ‘X’ shaped hole. - The
tensioner 112 operates by rotating about thehinge point 128. As thebody 102 is placed upon a surface, thelower arm 124 causes thetensioner 122 to rotate and slightly stretch thechalk line 112 with thetensioning arm 126. In some embodiments, the amount of tension applied by thetensioning arm 126 may be sufficient to snap thechalk line 112 and effectively place marks along the board. In other embodiments, the carpenter may push thebody 102 against the board and pull thechalk line 112 taught by pulling on thechalk line 112 in the area between thestanchions - The rewind crank 116 may be used to retract the
tape 110 andchalk line 112 into thebody 102. The rewind crank 116 may be connected to thetape spool 104 andchalk line spool 106 by various gears, pulleys, or other mechanisms such that thetape 110 andchalk line 112 may be retracted substantially simultaneously. In other embodiments, a return spring may be used in place of the rewind crank 116. In such embodiments, thetape spool 104 andchalk line spool 106 may be connected by a mechanism that allows for the simultaneous retraction of thetape 110 andchalk line 112. -
FIG. 2 is a partial cut away front view of theembodiment 100 of a marking apparatus. Thebody 202 has a tape housing 204 and achalk line housing 206. The return crank 208 is mounted so that it can retract the chalk line and tape into thebody 202. Thechalk line 210 is fed throughstanchions tip 212. Thewall 218 separates thechalk line housing 206 from the tape housing 204. Thechalk line housing 206 may have a door into which may poured a quantity of chalk dust.

The string end clip 316 may be engaged on the post 317 when the device is used as a marking instrument. - The embodiment 300 may be used as a separate tape measure and string line. For example, to use the embodiment 300 as a tape measure, the string end clip 316 may be disengaged from the
tape end clip 312 and stored in the stringend clip holder 318. The tape may be extended from thetape spool 304 by pulling on thetape end clip 312. The tape may be an elongated sheet of metal or plastic and may have graduations, marks, or other indicia for measuring or otherwise indicating distance. Similarly, the tape may be kept in the retracted position and the string may be extended to mark or indicate a straight line. -
FIG. 4 illustrates a perspective view of an embodiment 400 of the present invention of a marking apparatus. Thebody 402 contains atape spool 404 and astring spool 406. Atape locking lever 408 may lock the tape in a particular position. Achalk filling door 410 may be opened to receive powdered chalk or other marking medium that can be carried on thestring 414. Thetape end clip 412 has apost 417 that may receive thestring end clip 416. - The embodiment 400 contains a string retract crank 418 that may engage the
string spool 406 to retract thestring 414 into thebody 402. In some embodiments, thecrank 418 may engage the string spool directly or may engage the spool by means of gears. - In some embodiments, the tape may be retracted by a spring mechanism. In some embodiments, the string and the tape may be retracted simultaneously and collectively by a gear mechanism between the tape spool and the string spool. In other embodiments, the tape and the spring may be retracted separately and using separate devices. For example, the tape may be retracted with a spring powered mechanism while the string is retracted by a hand crank mechanism. Various retraction mechanisms may be used by those skilled in the art while keeping within the spirit and intent of the present invention.
- The
string 414 may carry chalk or other marking medium and may be used to transfer the marking medium to an article to be marked. In some instances, the string may contain powdered chalk, powdered ink, liquid ink, or other marking fluid or powder. -
FIG. 5 illustrates a perspective view of anembodiment 500 of the present invention of a marking apparatus. A measuringtape 502 contains a plurality ofapertures 504 at predetermined intervals or other spacing. Thetape clip 506 may be hooked over the edge of an article to mark. A chalk line 5 10 may be placed over thetape 502 by engaging thestring end clip 512 over thepost 508 of thetape end clip 506. Thestring 510 is placed directly on top of thetape 502, spanning theapertures 504. When thestring 510 is made taught, the chalk line 5 10 may be raised and released quickly to transfer the marking medium carried by thechalk line 510 through theapertures 504 and onto the item to be marked. This process is sometimes called ‘snapping a line’ in the trade. - The
apertures 504 may be selected to be of various shapes, sizes, and spacing to indicate various distances or marks as those skilled in the art may desire. For example, for framing houses in the United States, it may be conventional to mark studs at 16 inches apart. In such a case, theapertures 504 may be spaced 16 inches apart. In some cases, the shape of anaperture 504 may have a special meaning, such as the stud side of a mark. - In some cases, the measuring
tape 502 may have various marks or indicia for measuring distance or other functions as desired. -
FIG. 6 is a perspective view of anembodiment 600 of the present invention of a marking apparatus. Atape body 602 contains atape 604 and atape locking tab 606. Achalk line body 608 contains astring 610, astring end clip 612, a retraction crank 614, and achalk filling door 616. Thechalk line body 608 may removably engage thetape body 602 with a locking/locatingfeature 618. - The
embodiment 600 allows thestring line body 608 to be removed and separately used from thetape body 602, but be recombined in order to use apertures in thetape 604 to mask thechalk line 610 to make separate, distinct marks along the length of thetape 604. For example, thechalk line 610 may be used for marking a straight line while thetape measure 602 may be used to measure a certain distance. After such time, thechalk line 610 may be reattached to thetape measure 602 and used to mark a plurality of points along a distance. - Various locating and locking
mechanisms 618 may be used by those skilled in the art while keeping within the spirit and intent of the present invention. For example, thetape measure 602 and thechalk line 610 may snap together, may lock together using a mechanical linkage, may slidingly engage each other, or any other type of releasable engagement device or mechanism. - The foregoing description of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and other modifications and variations may be possible in light of the above teachings. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application to thereby enable others skilled in the art to best utilize the invention in various embodiments and various modifications as are suited to the particular use contemplated. It is intended that the appended claims be construed to include other alternative embodiments of the invention except insofar as limited by the prior art.
