DETAILED DESCRIPTION

[0017] Referring generally to the figures, a marking tool, shown as a carpenter pencil tool is shown according to an exemplary embodiment. Applicant has developed a number of improvements to carpenter pencil tools as described herein. In contrast to the carpenter pencil tool discussed herein, many carpenter pencil tools or holders may have difficulty securing and/or releasing the carpenter pencil from the holder within the working environment (e.g., on ladders, roofs, etc.). Applicant has designed an adjustment mechanism that allows a user to change the position of the carpenter pencil relative to the holder of the tool with one hand. The adjustment mechanism allows the user to alter the position of the carpenter pencil which can then be more easily accessed or grasped within the working environment (i.e., on a ladder, roof, etc.). In a specific embodiment, the adjustment mechanism includes a sliding device positioned for ease of access that can be actuated by a single hand or thumb. The adjustability of the carpenter pencil tool allows a user to reach and release the carpenter pencil when positioned in a variety of locations (i.e., attached to tool belt, clipped to pants, etc.), while the ability to perform the adjustment with a single hand allows for use when a second hand may not be available (i.e., holding workpiece, ladder, etc.).

[0018] Further, many carpenter pencil tools merely act as holders for the carpenter pencil or provide a way to attach to the carpenter pencil. Applicant has designed a compact carpenter pencil tool that provides additional functionality to the tool. In the specific embodiment, discussed herein the carpenter pencil tool includes structure providing compass functionality. The holder of the carpenter pencil tool extends along a longitudinal axis and includes a longitudinal cavity in which the carpenter pencil is received and/or secured within when the carpenter pencil tool is acting as a holder. An outer wall of the holder includes a recess configured to receive and engage the carpenter pencil when the carpenter pencil tool is being used as a compass. When the carpenter pencil is positioned within the recess, the carpenter pencil extends in a generally perpendicular direction to the longitudinal axis of the holder and/or the longitudinal cavity. A pointed object (i.e., nail, pin etc.) is extended through an opening in the holder in a direction generally parallel to the carpenter pencil at a desired location to act as the needle point or center point of the compass.

[0019] Applicant believes the carpenter pencil tool discussed herein that allows for use both as a holder and a compass, reduces the number of tools/markers a worker needs to carry, thereby increasing the efficiency of the worker. Similarly, the multi-functionality is useful for carpenters and/or builders who work in environments where it may be difficult or inconvenient to carry around more than one marking tool (i.e., carpenter's pencil for free hand marking, scribe compass and pencil, etc.).

[0020] Additionally, the holder design of the carpenter pencil tool discussed herein is sized to be used with carpenter pencils of various lengths (i.e., 17.8 cm, 24 cm, 30 cm, etc.), creating a carpenter pencil tool compatible with a variety of carpenter pencils. Designing a holder compatible with multiple sizes of a marking instruments reduces the number of marking instruments a worker needs to carry and/or interact with, again increasing the efficiency of the worker.

[0021] Referring to FIGS. 1-2, a marking or drafting tool, shown as a carpenter pencil tool 10, is shown. As will be discussed in greater detail below, carpenter pencil tool 10 is usable as a holder 12 to facilitate use of a carpenter pencil and also as a compass. Carpenter pencil tool 10 includes a holder and a pencil, shown as a carpenter pencil 14. As will be generally understood, a carpenter pencil is designed for use in construction environments (e.g., drawing or marking wood, building materials, etc.). In contrast to regular pencils, a carpenter pencil typically has a body or shaft with an elliptical or rectangular cross-sectional shape that prevents the carpenter pencil from rolling away, improves case of gripping (larger surface area), and allows for use of wider and thicker lead. Furthermore, the shape and lead density of a carpenter pencil allows for both thin, precision line markings and thick markings necessary for rough surfaces by rotating the carpenter pencil to specific angles.

[0022] Holder 12 includes a body 18 that extends along a longitudinal axis 36 (see e.g., FIG. 3) between a first end, shown as a gripping end 20 and a second end, shown as an opposing engagement or pencil end 22. Body 18 includes an upper or top wall 24 (in the orientation shown in FIGS. 1-2) with an opening, shown as elongated slot 26 defined in top wall 24. Body 18 has a length defined between gripping end 20 and engagement end 22. In various specific embodiments, body 18 has a length greater than 3 inches, specifically greater than 3.5 inches, and more specifically greater than 4 inches. In a specific embodiment, body 18 has a length of about 4.134 inches (e.g., 4.134 inches plus or minus 0.1 inches).

[0023] Elongated slot 26 extends along longitudinal axis 36 of holder 12. A first end of elongated slot 26 is positioned adjacent to engagement end 22 of the holder 12 and an opposing second end of elongated slot 26 is positioned adjacent to gripping end 20 of holder 12. A length of elongated slot 26 is defined between the first end and the second end. In various specific embodiments, elongated slot 26 has a length greater than 2.5 inches, specifically greater than 3 inches and more specifically greater than 3.2 inches. In a specific embodiment, elongated slot 26 has a length of about 3.274 inches (e.g., 3.274 inches plus or minus 0.1 inches).

[0024] In various embodiments, the elongated slot 26 has a length greater than 60% of the length of body 18, specifically greater than 70%, and more specifically greater than 75%. In a specific embodiment, the length of elongated slot 26 is about 79.2% of the length of body 18 (e.g., 79.2% plus or minus 2%).

[0025] An adjustment mechanism 27 includes elongated slot 26 and a switching device or slider, shown as slide button 28 that moves carpenter pencil 14 toward and/or away from a user and engagement end 22 of the body when slide button 28 is actuated by the user. The adjustability of the carpenter pencil 14 allows a user to more easily grasp and/or remove carpenter pencil 14 from holder 12 regardless of the location where carpenter pencil tool 10 is attached (e.g., tool belt, pants, etc.). Applicant believes the adjustment mechanism 27 discussed herein improves case of access to carpenter pencil 14 for a user.

[0026] As shown in FIG. 3, holder 12 and specifically body 18 includes a cavity 34. Cavity 34 extends along longitudinal axis 36 of holder 12. At engagement end 22, an opening shown as front opening 33 connects to cavity 34. Engagement end 22 further includes a front wall 30 connected to top wall 24 of body 18. Body 18 further includes opposing side walls 38 that each connect to top wall 24 and front wall 30. An elongated opening 40 is defined in each side wall 38.

[0027] When carpenter pencil tool 10 is assembled, carpenter pencil 14 is positioned within and/or received within cavity 34 and extends out of front opening 33. In such a position, a longitudinal axis 16 of carpenter pencil 14 is generally parallel to longitudinal axis 36 of holder 12. In a specific embodiment, longitudinal axis 16 of carpenter pencil 14 is colinear with longitudinal axis 36 of holder 12. When a user actuates slide button 28, carpenter pencil 14 and specifically a front surface or tip 32 of carpenter pencil 14 is moved relative to holder 12. Carpenter pencil 14 extends between tip 32 and an opposing gripping or engagement end 31.

[0028] As shown in FIG. 1, when carpenter pencil 14 is in a first non-extended position in which slide button 28 is positioned at gripping end 20, carpenter pencil 14 extends a first distance or length, L1 from front wall 30 and is securely held within holder 12. L1 is defined between front wall 30 of body 18 and tip 32 of carpenter pencil 14. When a user actuates slide button 28, carpenter pencil 14 moves into one of the various extended positions. In a second, extended position (see e.g., FIG. 2) carpenter pencil 14 extends a second distance or length, L2 from front wall 30. L2 is similarly defined between front wall 30 of body 18 and tip 32 of carpenter pencil 14. L2 is greater than L1.

[0029] In a specific embodiment, adjustment mechanism 27 allows for a range of adjustment or extension of carpenter pencil 14. In other words, carpenter pencil 14 is adjustable between a non-extended position in which the tip 32 extends a first distance beyond the opening of holder 12 and an extended position in which the tip 32 of carpenter pencil 14 extends a second distance beyond the opening of the holder 12.

[0030] Applicant believes this increased exposed length of carpenter pencil 14 improves ease of access for a user by reducing the distance a user has to reach carpenter pencil 14, while also avoiding other conventional methods for securing carpenter pencil (e.g., clipping, retractable line, screwing into holder, etc.) that may be difficult or awkward for a single hand.

[0031] Referring to FIG. 4, an exploded view of holder 12 is shown, according to an exemplary embodiment. In a specific embodiment, body 18 is formed from an upper body portion 42, a lower body portion 44, and a base 46. In various other embodiments, body 18 may be formed from a single, integral component.

[0032] Slide button 28 includes a user engagement portion 50 with an actuating surface 52. In a specific embodiment, actuating surface 52 includes a plurality of protrusions 54. Engagement portion 50 of slide button 28 further includes a connector 56 extending inward, toward cavity 34 when holder 12 is assembled. Connector 56 couples to a pencil engagement portion 58 that includes a recess 60 configured to receive and hold connector 56. Pencil engagement portion 58 includes an engagement surface 62 that interfaces against and provides a force onto carpenter pencil 14 to move carpenter pencil 14 as a user actuates slide button 28. Specifically, engagement surface 62 interfaces against gripping end 31 of carpenter pencil 14. When holder 12 is assembled, engagement surface 62 faces front opening 33. In other words, when a user applies a force to the slide button 28 greater than the retention force applied by the holder 12, the carpenter pencil 14 moves through the opening of the holder 12.

[0033] Engagement portion 50 extends in a generally parallel (i.e., parallel plus or minus 10 degrees) orientation to a surface of wall 38 of holder 12 and is positionable adjacent to both gripping end 20 of holder 12 and engagement end 22. Slide button 28 and specifically engagement portion 50 faces in a direction away from carpenter pencil 14.

[0034] As previously discussed, slide button 28 is positioned along a length of holder 12 defined between the gripping end 20 and the engagement end 22. In various embodiments, slide button 28 is positionable in uppermost (defined as engagement end) 30% of holder 12 and the lowermost (defined as gripping end) 30% of holder. In various embodiments, slide button 28 is positionable in the uppermost 25% of holder 12 and the lowermost 25% of holder 12. In other words, due to the length of elongated slot 26 relative the length of holder 12, slide button 28 is movable along a majority of the length of holder 12 allowing for increased adjustability and for using carpenter pencil tool 10 with carpenter pencils of various lengths (i.e., 17.8 cm, 24 cm, 30 cm, etc.).

[0035] Upper body portion 42 and specifically elongated opening 40 includes a plurality of shaped openings 64 positioned along elongated opening 40 and extending through side walls 38. As will be discussed in greater detail below, openings 64 can be configured and/or shaped to receive a pointed object when carpenter pencil tool 10 is being used as a compass. Each opening 64 provides a discrete location for marking a workpiece at a specific distance or measurement. Upper body portion 42 further includes a plurality of projections 66. Projections 66 extend downward, toward lower body portion 44 and are configured to couple to lower body portion 44.

[0036] Lower body portion 44 includes a plurality of recessed portions 72 configured to receive and couple to projection 66. Lower body portion 44 further includes an upward facing surface 68 that faces upper body portion 42. A retention component, shown as spring 70 extends inward from upward facing surface 68. Spring 70 pushes against carpenter pencil 14 to secure and/or hold carpenter pencil 14 within holder 12. In other words, spring 70 extends inward from a first (upward facing in the orientation shown in FIG. 4) toward a second opposing surface 90 (downward in the orientation shown in FIG. 4) of holder 12 and when the spring applies the retention force on carpenter pencil 14, the carpenter pencil 14 moves into engagement with downward facing surface 90 (see e.g., FIG. 8) to hold and/or secure carpenter pencil 14 within holder 12.

[0037] Base 46 includes an outward facing surface 74. A recess 76 is defined in outward facing surface 74. Recess 76 is configured to retain carpenter pencil 14 when it is in the compass position. A clip 48 is coupled to base 46. Clip 48 is configured to attach to an object such as a belt, tool bag, or pants of the user. Clip 48 additionally helps retain carpenter pencil 14 in the compass position. In other words, when carpenter pencil 14 is in a holding position, the carpenter pencil 14 is positioned in the cavity 34 and when the carpenter pencil 14 is in a compass position, the carpenter pencil 14 is positioned in the recess 76.

[0038] Referring to FIG. 5, a left perspective view of holder 12 is shown according to an exemplary embodiment. Recess 76 of holder 12 includes a surface 78. Surface 78 faces and interfaces against carpenter pencil 14 when carpenter pencil 14 is in the compass position. In a specific embodiment, each opening 64 includes an indicia or marking indicating to the user a distance to carpenter pencil 14 from opening 64 which determines a radius of a circle or arc or and/or a marking distance created using carpenter pencil tool 10.

[0039] Referring to FIG. 6, a left side view of carpenter pencil tool 10 with carpenter pencil 14 in a compass position is shown according to an exemplary embodiment. In the compass position, carpenter pencil 14 is positioned within recess 76 and below clip 48 (in the orientation shown in FIG. 6) at engagement end 22 of holder 12. When the carpenter pencil 14 is in the holding position, the carpenter pencil 14 extends along the longitudinal axis 36 of the holder 12. In contrast, the carpenter pencil 14 extends in a generally perpendicular (i.e., 90 degrees plus or minus 10 degrees) direction to the longitudinal axis 36 of the holder 12 and/or cavity 34. A distance between tip 32 and a center point of a first opening 64 defines a first radius R1.

[0040] When a user extends a pointed object, shown as nail 81 through the first opening 64, nail 81 acts as the needle point of the compass as carpenter pencil 14 draws a circle or arc with a radius R1 or simply marks a distance equal to R1. Nail 81 is extended through the holder 12 and specifically through one of the openings 64 in a direction generally parallel to the carpenter pencil 14 at a desired location or distance.

[0041] A second opening 64 is positioned along elongated opening 40. Second opening 64 is positioned between first opening 64 and gripping end 20 of holder 12. A distance between tip 32 and a center point of second opening 64 defines a second radius R2. A third opening 64 is positioned along elongated opening 40. Third opening 64 is positioned between second opening 64 and gripping end 20 of holder 12. A distance between tip 32 and a center point of second opening 64 defines a third radius R3.

[0042] In a specific embodiment, body 18 includes 9 openings 64 such that 9 distances and/or radiuses can be marked using carpenter pencil tool. In other embodiments, a different number of openings 64 are defined in body 18 (i.e., 4, 5, 6, 7, 10, etc.). In a specific embodiment, a distance between the centers of adjacent openings 64 is a ? inch. In various specific embodiments, carpenter pencil tool 10 can be used as a compass from ? an inch to 2? inches. In various specific embodiments, openings 64 are sized and/or shaped for use with a 16D nail.

[0043] Referring to FIGS. 7-8, views of carpenter pencil tool 10 in the first, non-extended position are shown, according to an exemplary embodiment. As previously discussed, when carpenter pencil 14 is in the non-extended position, slide button 28 is positioned at gripping end 20. The carpenter pencil 14 extends through front opening 33 and is securely held within holder 12. Spring 70 engages with carpenter pencil 14 and provides a retention force onto carpenter pencil 14. The retention force pushes and/or presses carpenter pencil 14 and specifically side surfaces 86 of carpenter pencil 14 against a downward facing surface 90 of top wall 24. Downward facing surface 90 of top wall 24 faces toward upward facing surface 68 and an upward or inward facing surface 88 of spring 70. In other words, spring 70 pushes carpenter pencil 14 into downward facing surface 90 to hold or retain carpenter pencil 14 within holder 12 resisting the movement of carpenter pencil 14 out of holder 12.

[0044] Referring to FIG. 8, a cross-sectional view of carpenter pencil tool 10 showing details of the engagement between slide button 28 and carpenter pencil 14 are shown, according to an exemplary embodiment. The engagement surface 62 of pencil engagement portion 58, interfaces against and provides a moving or adjustment force onto a distal end 82 of carpenter pencil 14 to move carpenter pencil 14 as the user actuates slide button 28. Distal end 82 of carpenter pencil 14 is positioned within cavity 34 and opposes proximal end 84. Proximal end 84 of carpenter pencil 14 includes tip 32.

[0045] When the user actuates slide button 28, connector 56 moves through elongated slot 26 on top wall 24 while engagement portion 58 slides or moves along upward facing surface 68 of body 18. As slide button 28 and carpenter pencil 14 are moved within body 18, the amount (i.e., length) of carpenter pencil 14 positioned outside of body 18 increases, allowing the user to more easily reach and grasp carpenter pencil 14. When the user is finished with carpenter pencil 14, carpenter pencil 14 can be returned to body 18 through front opening 33 and slide button 28 can be moved in a direction toward gripping end 20. Because the amount of carpenter pencil 14 positioned outside of body 18 is decreased, carpenter pencil 14 is securely held within holder 12.
