The present invention relates generally to construction, such as carpentry and the like and provides a tool employable to measure and to mark materials for cutting and to provide a user-formable offset guide surface whereby multiple substantially identical cuts may be achieved with a saw using the marks or offset guide surface.
In construction, a widely employed tool is the carpenter's square which is employed for measuring distance and angles and determining cutting lines and the like. Such a carpenter square, also sometimes known as a framing square or speed square, is a type of carpentry tool commonly used by carpenters, builders, and other home improvement aficionados. During construction, such as framing, a carpenter square gives the user the ability to measure and mark precise angled dimensions for complex projects like walls, doorways, roofs, rafters, stairways and other framing which requires precise measurements and subsequent cutting of materials.
Conventionally, carpenter's squares provide the user measuring and cut-marking components formed into a substantially triangular shaped device. Side edges on the body of the carpenter square allow for marking and cutting straight cut lines on lumber and for marking cut lines using slots.
Additionally provided, by conventional carpenter squares, are a combination of linear and angled edge surfaces. Some of the linear surfaces intersect at 90 degree angles to allow the user to mark the material for cutting to form perpendicular edges. Other formed edges on the body of conventional carpenter squares provide angled edges which allow for the tracing of cut lines to quickly mark 45 degree angles.
Formed into or imparted onto the body of conventional carpenter squares are also measurements, such as those employed upon tape measures and rulers. These depicted measurements allow the user to mark desired lines for material increments onto construction materials, such as wood or sheet rock, to allow for cutting them to desired sizes. Thereafter, using the lines or markings, the user employs a saw, such as a circular saw or table saw, to cut the materials to the correct size and correct angles.
The forgoing examples of related art in the field of conventional carpenter squares and the like, and limitation related therewith are intended to be illustrative and not exclusive, and they do not imply any limitations on the construction marking and measuring tool invention described and claimed herein. Various limitations of the related art will become apparent to those skilled in the art upon a reading and understanding of the specification below and the accompanying drawings.
The measuring tool device herein disclosed and described provides significant enhancement to the art of measuring and marking materials employed for construction. Such materials, for example only and in no way limiting, include wood, metal, sheet rock, and similar construction materials used for buildings and are cut to size and angular dimensions using power saws, such as a circular saw or table saw.
The measuring tool device has a body formed of planar rigid material, such as metal, which will endure the hardships encountered by tools on a construction site. However, the body may also be formed of other materials, such as polymeric material or composites, to provide a light weight mode of the measuring tool herein.
The body has a first body segment extending from a first end thereof to a second end in a straight line. At the second end of the first body segment is positioned a second segment which is in a fixed engagement and which extends traverse to the axis of the first body segment at a 90 degree angle or perpendicular to the first body segment.
A third body segment extends from the first end of the first body segment. This third body segment extends at a 45 degree angle from the engagement thereof to the first segment as do both side edges of the third body segment.
Side edges are also located on opposing sides of the first body segment and upon the second body segment in addition to those of the third body segment. These side edges provide respective linear surfaces for purposes of running a marking instrument thereon, such as for example, a pencil or pen or ink marker. The side edges of the three body segments intersect to allow the user to use the marking instrument to thereby mark measured locations and lines upon the construction material for cutting and the like. The side edges of the second body segment run perpendicular to the side edges of the first body segment and the side edges of the third body segment run at a 45 degree angle to those of the first body segment.
Communicating through the first body segment is a first slot. Through this first slot is positioned a releasable connector, such as a screw and nut. The locking component is employable to fix the position of a sliding member which is removably positionable to different distances and rotated angled positions relative to the first body segment.
Measurement indicia is preferably positioned along one or both edges of the first body segment and the second body segment and the third body segment. The measurement indicia may be etched into the planar surfaces of the respective body segments or may be imparted thereon, such as by using ink or paint or the like. The measurement indicia, for example, may be in inches or other conventional markings for distance to provide the user the ability to mark distance upon the construction materials for positioning thereof or cutting thereof.
Particularly preferred, in all modes of the device herein, is the provision of a removable cutting edge portion along one side edge of the second body segment to allow the removable cutting edge portion to also operate as a depth gauge. This removable cutting edge portion is removably engaged to extend from the side edge of the second body segment. Such a removable engagement is preferred in the form of a slot or recess formed thereon which will removably connect with an engagement edge running along one side edge of the removable cutting edge portion.
The engagement edge, currently, is a formed elongated opening on an outside edge of the second body segment which is shaped to slidably engage with the engageable edge of the removable cutting edge. This engagement edge would be formed to a shape complimentary to the interior shape of the elongated opening.
The user can cut this removable cutting edge along a determined cut line which is a distance from the engageable edge or the opposite edge of the second body segment. This forms a cut line edge for use in a repeating cutting process for multiple construction components formed for the construction material. The user may run a saw blade along the formed cut line to cut material. This provides for high repeatable accuracy in the cutting and formation of multiple construction components. During use such a guide is provided for repeatable measuring and cutting. A sliding member employed for other measurements will be rotated out of the way of the removable cutting edge. The removable cutting edge portion may be replaced once the repeating cutting is finished to allow the user to form another cut line, or it may be removed to allow for use of both sides of the second body segment for measuring.
Preferably, the material forming the removable cutting edge is material which is substantially rigid to thereby maintain a straight cutting edge but which may easily be cut to form that straight edge. Such material, for example, may be plastic or polymeric or composite materials which are inexpensive but will hold a shape and edge, once engaged to the first body segment.
Because the removable cutting edge portion is slidably engaged with the second body segment, it may also be employed as a depth gauge or measuring tool. This is accomplished by sliding the removable cutting edge in its engagement with either the second body segment or one end of the removable cutting edge in contact with the surface of the material being measured. Where the removable cutting edge portion is slid, measurement indicia, located on the edge of the second body segment, will show the distance the removable cutting edge has been displaced thereby providing a depth measurement.
Particularly preferred in all modes of the device herein is a removably engageable sliding member. The sliding member has a second slot formed axially therein which communicates between a first planar side surface of the sliding member and a second planar side surface thereof. Formed into the second planar side surface of the sliding member is a recess which surrounds the second slot. This recess provides an elongated recessed area for positioning of a head portion of a screw which is employed to removably hold the sliding member in the sliding engagement with the first body segment of the device. The recessed positioning of the head of the screw is preferred in that it maintains a planar second side surface of the sliding members. This planar second side surface is positionable against or in contact with construction materials. Of course, another connector in a similar configuration to a screw having a head portion positionable in the second slot may be used and is anticipated.
At one end of the sliding member is located a ledge which projects from a lower surface and which is employable to contact against side surfaces of construction material. Once the ledge is in contact with the desired construction material, pulling or pushing upon the sliding member will slidingly reposition it relative to the body of the device herein. This repositioning allows for measuring and marking of the construction material as needed by the user.
The sliding member may be placed in a removable fixed engagement with the body of the device, such as in a compressed engagement against the first body segment. This compressed engagement is accomplished by a tightening of the nut engaged to the threaded end of the screw which communicates through the first slot in the first body segment. So positioned, the device can be employed for repeated marking of construction materials with highly accurate measurements, since the distance is fixed by the compressed engagement formed.
For such measurements and marking of construction materials, the sliding member can be rotated to multiple positions in a circle extending around the screw and nut forming the compressed engagement. In one of many such positions the ledge on the sliding member can be employed to contact around an edge of the material to be marked and cut and a distance from the end of the sliding member to a side surface of the first body segment can be employed. In another of such compressed engagement positions, the sliding member can be rotated to allow the outside edge of the ledge to contact against a side surface of construction material, and a distance can be marked therefrom to a position upon the first body segment.
The ledge can extend in a fixed position projecting from the lower surface of the sliding member, or in a particularly preferred mode of the device herein, the ledge is rotationally engaged to the end of the sliding member. In the rotational engagement, the ledge may be rotated into a recess. This forms a completely planar lower surface of the sliding member which is easier to rotate around the body of the device. The sliding member is rotatable to an infinite number of positions in a circle around the screw engaging it to the first body member.
The sliding member may also be used as a plumb bob to determine a straight and level plumb line. This is accomplished by loosening the compressive engagement of the sliding member against the first body segment and allowing it to drop under the force of gravity. The axis and side edges of the sliding member will naturally assume a plumb positioning to allow the user to check the plumb accuracy of an existing board or other construction material or to provide a visual reference to mark a plumb line thereon.
A third slot is formed parallel to the axis of the first body segment and communicates through the first body segment. This fourth slot is employable to mark the surface of the material being measured by the device. In a similar fashion a fourth slot communicates through the third body segment and runs at a 45 degree angle to the third slot in the first body segment. This fourth slot is employable to use a pencil or marker to mark lines and measurement points as well as to mark a 45 degree angle upon the material being measured relative to the two side surfaces and third slot sides running on the first body segment.
