FIGS. 1-3 and FIG. 13 provide perspective views of a portion of an exemplary power tool 100 including an embodiment of a guard assembly 200 in accordance with aspects of the present disclosure. FIGS. 14-15 further provide side views of an embodiment of the guard assembly 200 and power tool 100. The guard assembly 200 includes a guard body 210 forming a perimeter partially surrounding the tool head 110. The guard body 210 may form an arcuate section relative to a centerline, such as a centerline axis CL extending through the tool head 110. The guard body 210 provides a wall extending outward along a radial direction R relative to the centerline axis CL and along a circumferential direction relative to the centerline axis CL. The guard body 210 extends radially outward from a cutter, such as cutting line 112, extending from the tool head 110.

The power tool 100 includes a linkage 130 connecting the guard assembly 200 to the tool head 110. For instance, the linkage 130 connects a housing of the tool head 110 to a portion of the guard assembly 200. The linkage 130 may be configured to receive the shaft 120, such as to allow user interfaces, power sources, or other operating features at the handle to selectively operate the tool head 110 as generally understood in the art.

The guard assembly 200 includes a mount body 220 connecting the guard body 210 to the shaft 120. The mount body 220 may form a channel 230 at which the shaft 120 may be positioned. For instance, the channel 230 may form at least a portion of a pathway with the linkage 130 at which the shaft 120 is received. However, it should be appreciated that channel 230 may generally form an interface at which linkage 130 may be positioned, at which shaft 120 may be positioned, or both.

The mount body 220 forms a slot 222 forming an opening extending through the mount body 220. For instance, slots such as described herein may include any opening having a major axis and a minor axis, or a length greater than a width, such as a racetrack, oval, rectangle, etc. In various embodiments, the slot 222 extends substantially along the radial direction R. Mount body 220 includes a wall 228 extending co-directional to a corresponding wall 218 at the guard body 210. For instance, walls 218, 228 may each extend co-directional to one another substantially along the radial direction R. In various embodiments, slot 222 is formed through wall 228 and extending along the radial direction R.

As depicted more clearly in FIGS. 4-9, guard body 210 forms an opening 212 configured to correspond in position to the slot 222 at the mount body 220. Opening 212 may form a hole (e.g., a circular opening). Wall 218 may form opening 212 to receive a handle assembly 240. The handle assembly 240 extends through slot 222 and opening 212. Handle assembly 240 is configured to selectively couple the guard body 210 to the mount body 220 at various desired positions relative to the radial direction R.

As depicted more clearly in FIGS. 6-10, mount body 220 includes a leg, hook, or other attachment member 226 configured to extend into an attachment opening 214 and track 215 formed at the guard body 210. In various embodiments, opening 214 is formed through wall 218 to allow the attachment member 226 to extend through the wall 218. Opening 214 may form a slot through which a detent 227 extends to position through the opening 214. Track 215 extends from opening 214. Attachment member 226 extended into opening 214 is allowed to travel along track 215. Track 215 may include a dimension less than the opening 214, such as to prevent detent 227 from escaping the track 215 except through opening 214.

In various embodiments, mount body 220 may include an opening 224 corresponding to opening 214 and attachment member 226. Opening 224 may allow the operator to see an alignment of openings 214, 224 relative to one another, or an alignment of attachment member 226 to opening 224, such as during positioning of the attachment member 226 through opening 214.

Referring to cross-sectional view in FIGS. 4-5, and further depicted in FIGS. 10-12, guard assembly 200 may include a base 250 positioned at a bottom face 219 of the wall 218. Base 250 is configured to attach to the wall 218. For instance, base 250 may attach to the bottom face 219 of wall 218 through a fastener interface 254. The fastener interface 254 may include a threaded opening configured to receive a fastener 255 therethrough and into a corresponding fastener interface 256 at the wall 218. Base 250 may include a stop wall 252 positioned to limit movement of the mount body 220 relative to the guard body 210 and base 250. For instance, stop wall 252 may be positioned to limit movement of the detent 227 along the track 215. Limited movement of the detent 227 may include limiting movement along the radial direction R to limit the detent 227 from traveling through the track 215 to the opening 214. For instance, the operator may position the attachment member 226 through the opening 214 and along track 215. The base 250 may be attached to the guard body 210 to position the stop wall 252 between the opening 214 and the track 215, such as to prevent the detent 227 from entering the opening 214 from the track 215 while the base 250 is attached to the guard body 210.

In some embodiments, base 250 may form a protrusion 258 corresponding to a position of the handle assembly 240, such as to allow the handle assembly 240 protrude toward the base 250 without undesired contact at the base 250.

Referring back to cross-sectional views provided in FIGS. 4-5, in some embodiments, handle assembly 240 includes a grip or knob 242 attached to a threaded body 246. The threaded body 246 may include a threaded shaft, shank, screw, or other member at which the threaded body 246 may releasably coupled to wall 218 of guard body 210 at opening 212. For instance, opening 212 may form a threaded interface configured to receive the threaded body 246. In some embodiments, a washer 244 may be positioned to form a wall between the knob 242 and wall 228. A lock 248, such as a lock washer, pin, or detent, may be positioned at the threaded body 246 distal to the knob 242. Lock 248 may limit movement of the handle assembly 240 at opening 212, such as to prevent the operator from pulling the threaded body 246 from the opening 212. Lock 248 may provide a surface facilitating clamping of the walls 218, 228 together, such as to limit or prevent movement of the walls 218, 228 relative to one another, such as to hold a radial position at slot 222.

In an exemplary embodiment of operation, the operator extends the handle assembly 240 through slot 222 and opening 212. The operator positions the guard body 210 along the radial direction R by sliding along the slot 222. The operator screws the handle assembly 240 into opening 212 to tighten the guard body 210 and the mount body 220 together, such as to clamp the components together and retain a desired position along the radial direction R. To change the desired position, the operator at least partially unscrews the handle assembly 240 to loosen the coupling of guard body 210 and mount body 220, such as to allow the components to slide radially forward or backward along slot 222 as desired.

Referring to FIGS. 9 and 16, in still various embodiments, guard body 210 may include a first guard body portion 210A separable and releasably coupled to a second guard body portion 210B. A fastener assembly 211 attaches the first and second guard body portions 210A, 210B to one another. Referring to FIG. 16, in some embodiments, the fastener assembly 211 includes a threaded fastener 262 extending through openings 272A, 272B formed respectively at guard body portions 210A, 210B. The fastener assembly 211 may include one or more washers 264, 266 positioned between a head of the threaded fastener 262 and the guard body 210 (e.g., such as guard body portion 210B as depicted). A retaining clip 270 may be positioned on the threaded fastener 262 between the guard body portions 210A, 210B, such as to prevent the threaded fastener 262 from exiting at least one of the guard body portions 210A, 210B (e.g., such as guard body portion 210B as depicted). A retainer 268 may be positioned at the guard body portion 210A, such as to retain and fasten the fastener 262 and attach the guard body portions 210A, 210B together.

Referring back to the exemplary bottom-up views of FIGS. 12A-12B, in various embodiments, guard assembly 200 includes a first line trimmer 274. The first line trimmer 274 may be mounted at the first guard body portion 210A. In some embodiments, the first line trimmer 274 is mounted at or proximate to an interface 213 of the first guard body portion 210A to the second guard body portion 210B.

In still various embodiments, guard assembly 200 includes a second line trimmer 276. The second line trimmer 276 may be mounted at the second guard body portion 210B. In some embodiments, the second line trimmer 276 is positioned at the second guard body portion 210B distal to the first line trimmer 274, such as distal to the interface 213 of the first and second guard body portions 210A, 210B. For instance, the second line trimmer 276 may be positioned at or proximate to corner 217 of second guard body portion 210B distal to interface 213. Corner 217 corresponds to a portion of the second guard portion 210B proximate to cutting line 112 rotating toward the guard assembly 200. As such, second line trimmer 276 is positioned more proximate than first line trimmer 274 to the cutting line 112 rotating toward the guard assembly 200, such as depicted schematically via rotational arrow 103. In still some embodiments, second line trimmer 276 is positioned more radially outward (e.g., radius R₂) relative to tool head 110 than first line trimmer 274 (e.g., radius R₁).

The first line trimmer 274 may include a line-cutoff blade configured to cut the trimmer line 112 from the tool head 110 to a desired working length. The second line trimmer 276 may include a line-cutoff blade configured to cut the trimmer line, such as to prevent trimmer line 112 from damaging the second guard body portion 210B.

In various embodiments, the first line trimmer 274 is configured to cut the trimmer line 112 to the desired length when the second guard body portion 210B is detached from the guard assembly 200. The second line trimmer 276 positioned such as described cuts the trimmer line 112 to a first length longer than a second length cut from the first line trimmer 274. Such positioning may provide an initial cut to the trimmer line 112 at the second line trimmer 276, and a final cut or adjustment to desired length at the first line trimmer 274. The initial cut may protect the guard assembly 200, such as to protect the guard assembly 200 at the second guard body portion 210B. The initial cut of the trimmer line 112 from second line trimmer 276 and second guard body portion 210B may facilitate passing the trimmer line 112 behind the guard assembly 200 into contact with the first line trimmer 274.

Embodiments of the power tool and guard assembly depicted and described herein may advantageously and beneficially facilitate an operator re-positioning or removing a guard for the power tool, such as to adjust a cutting position or to replace the component.
