[0059] Referring generally to the accompanying drawings, various embodiments of a hand tool configured to engage and drive lock nuts are shown. In specific embodiments, the tool is configured to engage multiple lock nuts of different sizes.

[0060] In the illustrated embodiment, the tool is a lock nut wrench including a handle with a twisted portion extending to the head. In other embodiments, the lock nut wrench includes a handle with a straight, untwisted portion extending to the head. In one embodiment, the head of the lock nut wrench includes two downwardly projecting protrusions located at either end of a curved headstock. In such an embodiment, these downwardly projecting protrusions engage a lock nut, wherein the curved headstock rests on top of the lock nut when engaged. In another embodiment, at least three lock nut wrenches of different sizes are present, shaped to be stacked or nested together. In such an embodiment, the intermediate wrench (e.g., a 3 / 4-inch wrench) includes a magnet (e.g., a magnet included in the handle) to hold the smaller and larger wrenches together when nested.

[0061] Reference Figures 1 to 14 The diagram illustrates various aspects of a locking nut wrench assembly 110. The locking nut wrench assembly 110 includes a first locking nut wrench 210, a second locking nut wrench 310, and a third locking nut wrench 410. Locking nut wrenches 210, 310, and 410 are connected to a clamp 124 of an attachment device 120, which can also be connected to other items, such as rings or belt loops, via a clamp 122.

[0062] Reference Figures 4 to 10 The image shows various aspects of a locking nut wrench 210. The locking nut wrench 210 includes a handle 220, an arm 230 connected to the handle 220, and a head 240 including a wrench head, which is shown as a curved head bar 242 connected to the arm 230.

[0063] A handle 220 is configured to be gripped by a user and extends from a first end 222 along a first longitudinal axis 226 to a second end 224. The handle 220 is coupled to an attachment device 120 via an aperture 228. In various embodiments, the handle 220 defines an aperture 228 configured to receive a coupling device, such as the attachment device 220, and the aperture 228 is closer to the second end 224 than the first end 222. An arm 230 extends the handle 220 from the first end 232 along a second longitudinal axis 236 defining an angle 238 relative to the longitudinal axis 226 to the second end 234, and in various embodiments, the angle 238 is a non-zero angle. In various embodiments, the second longitudinal axis 236 is perpendicular to the first longitudinal axis 226. In various embodiments, both the arm 230 and the lever 240 are positioned on a second side 229 of the handle 220, opposite to the first side 227 of the handle.

[0064] The second longitudinal axis 236 defines an angle 238 relative to the first longitudinal axis 226 of the handle 220 and / or the upper surface 221 of the handle 220. In various embodiments, the upper surface 221 defines a plane parallel to the first longitudinal axis 226 of the handle 220. In various embodiments, the angle 238 is between 80 degrees and 100 degrees, and more specifically between 85 degrees and 95 degrees, and even more specifically 90 degrees.

[0065] A curved head post 242 extends from arm 230 along plane 258, which defines an angle 257 relative to a second longitudinal axis 236. In various embodiments, angle 257 is non-zero. In various embodiments, plane 258 is parallel to a first longitudinal axis 226. In various embodiments, plane 258 is perpendicular to the second longitudinal axis 236. In various embodiments, plane 258 is parallel to a plane defined by lower surface 250. In various embodiments, angle 257 is between 80 and 100 degrees, and more specifically between 85 and 95 degrees, and even more specifically 90 degrees.

[0066] A curved head rod 242 extends circumferentially from a first end 244 to a second end 246. The rod 242 extends from the arm 230 along a first direction 243 to the first end 244, and from the arm 230 along a second direction 245 opposite to the first direction 243 to the second end 246. In various embodiments, the curved head rod 242 extends circumferentially about an axis 248 and is centered on the axis 248. The curved head rod 242 defines a lower surface 250 opposite to the handle 220. In various embodiments, each of the first protrusion 260 and the second protrusion 270 extends beyond the lower surface 250. In use, the lower surface 250 abuts against a locking nut against which the first protrusion 260 and the second protrusion 270 engage.

[0067] The curved headstock 242 extends circumferentially about axis 248 between the first protrusion 260 and arm 230 at a first angle 252, which is between 80 and 100 degrees, and more specifically between 85 and 95 degrees, and even more specifically 90 degrees. The curved headstock 242 extends circumferentially about axis 248 between the second protrusion 270 and arm 230 at a second angle 254, which is between 65 and 85 degrees, and more specifically between 70 and 80 degrees, and even more specifically 75 degrees. In various embodiments, the second angle 254 is smaller than the first angle 252. In various embodiments, both the second angle 254 and the first angle 252 are at least 60 degrees. In various embodiments, the second angle 254 is at least 10 degrees smaller than the first angle 252. In various embodiments, the second angle 254 is no more than 20 degrees smaller than the first angle 252. In various implementations, the second angle 254 is 10 to 20 degrees smaller than the first angle 252.

[0068] A first protrusion 260 and a second protrusion 270 extend from the curved head bar 242. In various embodiments, the first protrusion 260 extends from a first end 244 of the bar 242 away from the handle 220, and the second protrusion 270 extends from a second end 246 of the bar 242 away from the handle 220, and the first protrusion 260 and the second protrusion 270 are configured to engage a locking nut. The first protrusion 260 defines an inner surface 262 generally facing the second protrusion 270, and the second protrusion 270 defines an inner surface 272 generally facing the first protrusion 260. The inner surface 262 defines a plane 266, and the inner surface 272 defines a plane 276. The first protrusion 260 defines a lower surface 264, and the second protrusion 270 defines a lower surface 274, each of the lower surfaces 264 and 274 being opposite to the handle 220.

[0069] The first protrusion 260 is 268 radii away from the center 259 of the protrusion, and the second protrusion 270 is 278 radii away from the center 259 of the protrusion. In various embodiments, radii 268 and 278 define an angle 280, which is between 165 degrees and 185 degrees, and more specifically between 170 degrees and 180 degrees, and even more specifically 175 degrees.

[0070] In use, the first protrusion 260 and the second protrusion 270 engage and abut against the feature portion of the locking nut, so that the user can rotate the handle 220 to cause the locking nut to rotate. For example, the first protrusion 260 engages and abuts against the locking nut (see, for example, see...). Figure 16 The second protrusion 270 engages against the locking nut (see, for example, the locking nut 540) with a protrusion or recess, and the second protrusion 270 engages against the locking nut (see, for example, the locking nut 540).
