Description

  This application is based on US Provisional Patent Application No. 61 / 660,715 (filing date June 16, 2012), provisional application No. 61 / 664,049, the contents of each application being incorporated herein by reference in its entirety. Priority is given to filing date of June 25, 2012), provisional application number 61/714, 172 (filing date October 15, 2012), and provisional application number 61/714, 885 (filing date October 17, 2012) Claim the right.

  The present disclosure relates to the design of laser blades used as marking tools, in particular, standard laser knives for writing and drawing on various materials.

  Carpenters, builders, designers, contractors and artisans commonly use carpenter pencils to mark on a variety of materials. Because the carpenter pencil has a rectangular or oval cross section, it is possible to rotate the pencil and draw thick or thin lines as needed. Carpenter's pencil core must have strength enough to bear the load for marking rough surfaces, and at least one must have a thin core that can draw an accurate line on which a blade, saw blade or engraving blade is a standard . With a wooden carpenter pencil you have to frequently scrape the pencil to make it thin and accurate. Typically, the pencil is cut with a knife and the wood around the core is cut and then the core is sanded with a sandpaper to obtain a pointed pencil tip. With a mechanical carpenter's pencil, there is no need to scrape, but the disadvantage is that it is difficult to change and store the core due to its complicated design, and a core detent supporting the core is used. When writing on rough surfaces, the core breaks well due to stress. In addition, the detent may slip during use, and the core may return into the pencil. In addition, carpenter pencils and other marking tools used by carpenters are less accurate because they can not be placed exactly against straight edges (such as rulers, triangles, etc.) due to their non-circular large casing.

  The present disclosure relates to the design of marking devices that can be used in place of carpenter's pencils to draw lines and shapes on various rough surfaces such as concrete, wood, carpet, tiles, cardboard, drywall (masonry wall), stone etc. It is a thing. The marking device in the present disclosure does not require pencil sharpening or polishing, and can draw thin lines. Thus, the present marking device wears quickly when the pencil core is written on a rough surface, and has clear advantages over conventional wood carpenter pencils, which often must be scraped. On the one hand, the present marking device always provides sharp edges, even when used to write on rough surfaces. Also, because the marking device has flat edges, it can be aligned perpendicular to the work surface and can be placed in contact with the tool so that even rough surfaces can be straight and accurate. The lines or shapes drawn using this marking device can serve as a basis for shaving and engraving. The marking device can also be used to write dimensions or other instructions on the work piece.

  The marking device of the present disclosure is designed for use with a support frame that protects at least a portion of the marking device. It is to prevent the marking device from being damaged when not in use. The support frame acts as a handle for grasping and using the device. The support frame is a user-friendly design that allows the marking device to be attached to and removed from the frame quickly and easily.

  The first embodiment of the present disclosure is a marking blade. The marking blade includes a planar laser blade having a longitudinally extending marking edge. At least a portion of the marking edge is made of marking material capable of drawing clear markings on various surfaces.

  The second embodiment of the present disclosure is a marking blade that includes a thin plate configured as a laser blade. The thin plate includes a longitudinally extending marking edge, a portion of the marking edge being constituted by a pocket for receiving the marking tip. The marking tip is constituted by a marking material which is used to mark various surfaces sharply.

  A third embodiment of the present disclosure is a marking device comprising a thin flat plate constituting a laser blade and a support frame consisting of a proximal end and a distal end. The proximal end of the support frame comprises a handle for gripping the support frame, and the distal end comprises a case having a positioning member. The thin planar plate of the marking device comprises a longitudinally extending marking edge and at least a portion of the marking material for providing a sharp marking on various surfaces. At least a portion of the thin planar plate is comprised of one or more alignment structures used to attach to the positioning members of the casing.

As shown in FIGS. 7A-7C, cutouts / notches 25 are formed in both edge 14 and marking edge 16 in certain embodiments. In another embodiment, as shown in FIGS. 8A-8C, a cutout / notch 25 or other alignment feature is provided at the center of the marking device 10. FIG.

  In certain embodiments, support frame 30 and marking device 10 are disposable. The support frame 30 can be reused in other embodiments. If the marking device 10 wears in such an embodiment, it may be changed to a replaceable marking device.

  In the embodiment, the support frame 30 is composed of a proximal end 32 and a distal end 34. The distal end 34 is for attaching the marking device 10, and the proximal end 32 acts as a handle for the user when using the marking device. In one embodiment, the distal end 34 is provided with a safety cover to protect the marking device 10 when not in use. When drawing or writing on a surface, the marking device 10 can be pushed open from the case. In such embodiments, the proximal end 32 may be equipped with a manual switch (eg, a slider for sliding with a thumb) to push or slide the marking device 10 out of the safety cover. Also, switches or triggers for pushing the marking device can be located anywhere on the support frame 30. The marking device 10 can be placed in a safety case when not in use. For example, release of the switch / trigger on the proximal end 32 allows the marking device 10 to automatically enter the case. Such an arrangement protects the marking device 10 from damage. In another embodiment, the distal end 34 is simply configured to secure the marking device 10 without a safety case. A removable cap may be provided to protect the marking device 10 when not in use in such a configuration.

  In these embodiments, the marking device 10 is of the same dimensions as a conventional laser blade and is adapted to be mounted on a retractable or collapsible utility knife (e.g., a STANLEY knife). The utility knife plays the role of the support frame 30 in such an embodiment. In a particular embodiment, the marking device 10 is a combination of a conventional laser blade for cutting and engraving on one side and a marking tool for drawing and writing on the opposite side. This combination blade can be used with utility knives.

  FIG. 9 shows the marking device 10 attached to the support frame / utility knife 30. FIG. In the present embodiment, the average thickness of the marking device 10 in the form of a laser blade is 0.025 "to 0.035", the length is 2.425 "(61.595 mm), and the height is 0.. 735 "(18.669 mm) to 0.75" (19.05 mm). In the present embodiment, the marking edge 16 is very slim, and an accurate line can be drawn on any surface. In one embodiment, the thickness of the line drawn by the marking device 10 is about 0.025 "to 0.035".

  In a particular embodiment, the marking device 10 is adapted to be attached to a snap-off utility knife 50 in the form of a snap-off laser blade. 10A shows the snap-off marking device 10, and FIG. 10B shows the snap-off marking device 10 attached to the snap-off utility knife 50. FIG. The blade portion of the snap-off marking device 10 can be broken to provide a new sharp marking edge 16. It can be retracted for safe storage when the blade is not in use. In some embodiments, the snap-off marking device 10 is adapted to be attached to a snap-off utility blade without an individual flat blade, ie, no snap-off portion.

  By configuring the marking device 10 as a laser blade, the utility knife can optionally be used as a carpenter pencil. Such a mechanism has many advantages over standard carpenter pencils. For example, utility knives are easier to grasp than carpenter pencils, and they are used as general tools by carpenters, builders, contractors and craftsmen. The utility knife laser blade can be replaced with the marking device 10 and easily made into a carpenter pencil. If attached to a utility knife, the marking device 10 is less likely to be damaged. For example, it will not break if put in a cage with heavy tools.

  Other advantages of the present invention will be understood by those skilled in the art from the specification and the embodiments presented herein.
