DETAILED DESCRIPTION

FIG. 1 illustrates a perspective view of a measuring device connected to a guide bar of a chainsaw, in accordance with an embodiment of the disclosure. According to the present disclosure, a measuring device 100 is provided that facilitates use of a chainsaw 104 to cut down fallen trees, limbs, or other items into logs or sticks of repeatable lengths. For example, the measuring device 100 described herein may allow a user to efficiently measure out lengths of firewood to a desired length. As a result, the cut firewood may have a consistent or near consistent length, aiding in stacking, packaging, storing, and/or use in a fireplace. The measuring device 100 may also improve productivity, as the measuring device 100 may allow quick and efficient measurement of firewood cut lengths without stopping.

The measuring device 100 may include a simple design, allowing the measuring device 100 to be attached to most, if not all, chainsaws. For example, as described more fully below, the measuring device 100 is designed for attachment to a guide bar 108 of the chainsaw 104. Depending on the embodiment, the measuring device 100 may be attached near the distal end of the guide bar 108. The measuring device 100 may easily and quickly attach to the guide bar 108, such as via a simple mechanism as described below. For example, the measuring device 100 may attach to the guide bar 108 using a threaded fastener (e.g., a nut, wingnut, bolt, etc.). The attachment means may increase a strength and/or stiffness of the measuring device 100 while also reducing twisting of the measuring device 100 (e.g., a twisting tending to loosen the measuring device 100).

As shown in FIG. 1, the measuring device 100 may extend laterally from the guide bar 108, such as orthogonal or near orthogonal from the guide bar 108, although other configurations are contemplated. Although illustrated as attached to the right side of the guide bar 108 (as viewed from a user's point of view when using the chainsaw 104), the measuring device 100 may be attached to the left side of the guide bar 108 based on user preference, site conditions, tree placement, user/bystander positioning, etc.

During use, the measuring device 100 may be positioned adjacent to a tree, log, or other item to be cut to define one or more cut locations for the chainsaw 104, as detailed below. For example, the measuring device 100 may be used to set a consistent or near consistent length between cuts along the tree or log. For instance, an initial cut may be defined by indexing the measuring device 100 against the end of the tree or log. Once a cut has been made on the tree or log, the next cut may be defined by indexing the measuring device 100 against the previous cut. This process may be repeated until the entire tree or log is cut down into consistent lengths.

FIG. 2 illustrates an exploded view of the measuring device 100 of FIG. 1, in accordance with an embodiment of the disclosure. The measuring device 100 may include many configurations for defining a cut location for chainsaw 104. Referring to FIG. 2, the measuring device 100 may include a length indicator 202. The length indicator 202 may provide an indication of a proper or desired length for cutting an item (e.g., firewood logs) using chainsaw 104. For example, the length indicator 202 may have a length defined between a first end 206 and a second end 208, the length defining a length of cut. As shown, the first end 206 may be threaded, and the second end 208 may include a cap 212, although other configurations are contemplated.

The length indicator 202 may be formed of a first material easily cut by a chainsaw chain. In this manner, should the length indicator 202 be touched accidentally by another running chainsaw, the length indicator 202 will be cut or nicked without posing a safety hazard from flying debris or pulling the chainsaw 104 and/or user towards the chain of the other running chainsaw. In embodiments, the length indicator 202 may include or be formed from a polyvinyl chloride (PVC) pipe (e.g., ½ inch PVC pipe).

The length indicator 202 may have various lengths. For example, the length indicator 202 may be provided with a 12-inch length, a 14-inch length, a 16-inch length, or an 18-inch length, among other lengths. As a result, the length indicator 202 may be replaced with a second length indicator, the second length indicator having a different length. In some embodiments, the length indicator 202 may be cut down to a desired length.

With continued reference to FIG. 2, the measuring device 100 may include an adapter assembly 220. The adapter assembly 220 may be coupled to the length indicator 202. For example, the adapter assembly 220 may be threaded to the first end 206 of the length indicator 202. As shown, the adapter assembly 220 includes a body 222 and an attachment portion 224 extending from the body 222. The attachment portion 224 may be configured for positioning through an aperture defined in the guide bar 108, as detailed below. Positioning the attachment portion 224 through the guide bar 108 may at least partially attach the measuring device 100 to the guide bar 108, as further explained below.

The adapter assembly 220 may be formed of a second material different than the length indicator 202. For instance, the adapter assembly 220 may be formed of metal, such as steel, iron, stainless steel, brass, or other metals. In some embodiments, the attachment portion 224 may be a separate element connected to the body 222, or the attachment portion 224 may be formed integrally with the body 222. The attachment portion 224 may include or be defined by a threaded rod 228.

As shown, the measuring device 100 may include a fastening assembly 234 for coupling to the attachment portion 224 of the adapter assembly 220. The fastening assembly 234 may include many configurations, including a fastener 236 and a magnet 238. The fastener 236 may couple the fastening assembly 234 to the attachment portion 224 (e.g., via threaded engagement with the threaded rod 228). Depending on the embodiment, the fastener 236 may include a wing nut 242 for threading to the threaded rod 228 to secure the measuring device 100 to the guide bar 108. The magnet 238 may magnetically couple the fastening assembly 234 to the guide bar 108.

Attachment of the fastening assembly 234 to the adapter assembly 220 may trap at least a portion of the guide bar 108 between the adapter assembly 220 and the fastening assembly 234. For example, as described more fully below, at least a portion of the guide bar 108 may be configured to be trapped between the body 222 of the adapter assembly 220 and the magnet 238 of the fastening assembly 234. Such configurations may provide a secure attachment of the measuring device 100 to the guide bar 108. For instance, the attachment may provide sufficient lateral and/or rotational strength and stiffness.

FIG. 3 illustrates a process of preparing guide bar 108 to receive measuring device 100, in accordance with an embodiment of the disclosure. Referring to FIG. 3, a punch 302 and hammer 304 may be used to punch out an aperture 308 in guide bar 108. For example, the aperture 308 may be formed by punching out an existing hole in guide bar 108. As shown, aperture 308 may be formed near a distal end of guide bar 108, although other configurations are contemplated.

FIG. 4 illustrates an attachment of measuring device 100 to guide bar 108, in accordance with an embodiment of the disclosure. Referring to FIG. 4, the measuring device 100 may be attached to guide bar 108 by inserting attachment portion 224 (e.g., threaded rod 228) of adapter assembly 220 through the aperture 308. The attachment portion 224 may be inserted until the body 222 of adapter assembly 220 bottoms out against one side of guide bar 108 (e.g., against the right side of guide bar 108 as shown in FIG. 4). Once the attachment portion 224 is inserted through aperture 308, the fastening assembly 234 may be secured to the attachment portion 224, such as via threading the wing nut 242 onto the threaded rod 228. The fastening assembly 234 may be threaded onto the attachment portion 224 until the fastening assembly 234 (e.g., magnet 238) bottoms out against the opposite side of guide bar 108 (e.g., against the left side of guide bar 108 as shown in FIG. 4). As a result, at least a portion of the guide bar 108 may be trapped, sandwiched, or positioned between the adapter assembly 220 and the fastening assembly 234. In embodiments, tightening the fastening assembly 234 may pull the adapter assembly 220 and magnet 238 against opposing sides of guide bar 108 to secure the measuring device 100 in place. The magnet 238 may strengthen the attachment of the measuring device 100 to the guide bar 108. For example, once the fastening assembly 234 is tightened, the magnet 238 may limit or reduce twisting of the measuring device 100 on the guide bar 108. As a result, the magnet 238 may limit or reduce undesired loosening of the fastening assembly 234.

FIG. 5 illustrates use of the measuring device 100 to define a cut location for chainsaw 104, in accordance with an embodiment of the disclosure. The measuring device 100 may be used to cut a fallen tree 504 (or other item) into multiple sections or logs 506 of repeatable lengths. For example, the measuring device 100 may aid a user to set a consistent or near consistent length between cuts along the fallen tree 504. As shown, a first cut 510 may be made in the fallen tree 504. The chainsaw 104 may then be moved down the fallen tree 504 until the second end 208 of the measuring device 100 aligns with the first cut 510, upon which a second cut 512 may be made in the fallen tree 504. This process may be repeated until the entire fallen tree 504 is sectioned.

As shown, the first cut 510 and second cut 512 may be only partial cuts into the fallen tree 504, such that the partial cuts are alignment cuts only. Once the fallen tree 504 is sectioned with the partial cuts, the user can then go back and complete each cut, with either the measuring device 100 removed or still attached to the guide bar 108. For example, the alignment cuts may be made using the end or tip of the guide bar 108 where the measuring device 100 is located. The complete cuts can then be made near the bumper spikes of the chainsaw 104. Such embodiments are exemplary only, and the fallen tree 504 may be cut down using a different technique. For instance, each cut may be a complete cut initially, with the second end 208 of the measuring device 100 aligning with the freshly cut end of the fallen tree 504 to make the next cut.

FIG. 6 illustrates a removal of the measuring device 100 from the guide bar 108, in accordance with an embodiment of the disclosure. Removal of measuring device 100 from guide bar 108 may be accomplished by following the procedure outlined above in reverse order. For example, fastening assembly 234 may be removed from the adapter assembly 220, such as unthreaded from the threaded rod 228. Once the fastening assembly 234 is removed from the adapter assembly 220, the attachment portion 224 may be removed from the aperture 308 to remove the measuring device 100 from the guide bar 108.

FIG. 7 illustrates an additional measuring device 700, in accordance with an embodiment of the disclosure. Except as otherwise noted below, the measuring device 700 illustrated in FIG. 7 may be similar to the measuring device 100 described above. For instance, measuring device 700 may include a length indicator 702, an adapter assembly 704, and a fastening assembly 706. The length indicator 702 may be similar to length indicator 202 described above. The adapter assembly 704 may be coupled to the length indicator 702, such as via threaded attachment.

The fastening assembly 706 may couple to the adapter assembly 704. The fastening assembly 706 may include a fastener 710 coupling the fastening assembly 706 to the adapter assembly 704, and a magnet 712 magnetically coupling the fastening assembly 706 to the guide bar 108. As shown, the fastener 710 may be a bolt for threading to the adapter assembly 704. In such embodiments, the bolt may be positioned within the aperture 308 of guide bar 108 to attach measuring device 700 to the guide bar 108, the attachment portion of adapter assembly 704 being a female threaded portion to receive the bolt.
