[0042] As used herein, terms of approximation, such as approximately, substantially, or about, refer to being within manufacturing or engineering tolerances. For example, terms of approximation may refer to being within a five percent margin of error.

[0043] Referring now to FIG. 1, a perspective view of a helmet 10 is provided, in accordance with an example embodiment. The helmet 10 may be configured as a safety helmet, such as a hard hat. The helmet 10 can include a plurality of straps 11. The helmet 10 can include a buckle 100 that is coupled to the plurality of straps 11.

[0044] Referring now to FIGS. 2, a perspective view of a buckle 100 is provided, in accordance with an example embodiment. The buckle 100 may define an X direction, a Y direction that is orthogonal to the X direction, and a Z direction that is orthogonal to the X direction and the Y direction (FIG. 5). The X direction may be a longitudinal direction L and the Y direction may be a transverse direction T (FIG. 5).

[0045] The buckle 100 may include an outer assembly 200 and a base assembly 300. The outer assembly 200 of the buckle 100 can be removably coupled to the base assembly 300. The buckle 100 can include a plurality of strap attachment openings 102. For example, the outer assembly 200 may define a strap attachment opening 102 and the base assembly 300 may define a strap attachment opening 102. The straps 11 may extend through the strap attachment openings 102.

[0046] Referring now also to FIGS. 3-8, various views of at least a portion of the buckle 100 are provided, in accordance with an example embodiment. FIG. 3 provides a top perspective view of the buckle 100 with the release member 220 hidden. FIG. 4 provides a top perspective view of the base assembly 300. FIG. 5 provides a top view of the base assembly 300. FIG. 6 provides a bottom perspective view of the base assembly 300. FIG. 7 provides a bottom perspective view of the outer assembly 200. FIG. 8 provides an exploded view and a cross-sectional view of the buckle 100.

[0047] In various examples, the base assembly 300 can include a base 310. The outer assembly 200 can include a connector 210, a release member 220, and a shaft 230. The release member 220 can be pivotably coupled to the connector 210 with the shaft 230. The connector 210 may be positioned directly on the base 310. The connector 210 may be positioned between, such as directly between, the base 310 and the release member 220 along the Z direction.

[0048] With reference to FIGS. 4-6, the base 310 may include a flange 320. The flange 320 can include a ramped portion 322. A surface of the ramped portion 322 may extend at an angle relative to a plane defined by the longitudinal direction L and the transverse direction T. The angle may be at least 10 degrees and up to 60 degrees.

[0049] The base 310 may include a protrusion 332 that extends from the base 310. The base assembly 300 may include an arm 330 that extend from the base 310. The protrusion 332 may extend from a distal end of the arm 330. In various examples, a channel 331 is defined at least partially around the arm 330 and the protrusion 332. As such, the arm 330 and the protrusion 332 may be able to flex relative to the base 310. As best seen in FIG. 6, the arm 330 may extend at an angle relative to a plane defined by the longitudinal direction L and the transverse direction T. The base 310, the flange 320, and the arm 330 may comprise of a non-ferromagnetic material, such as plastic.

[0050] The protrusion 332 may include a nub 333. The nub 333 may be positioned on an upper portion of the protrusion 332. The nub 333 may define an angle that extends relative to the longitudinal direction L and the transverse direction T. The angle may be at least 10 degrees and up to 60 degrees.

[0051] The base assembly 300 may include a first base magnet 340 and/or a second base magnet 350 (FIG. 6). For example, the first base magnet 340 may be positioned at least partially within the protrusion 332. The second base magnet 350 can be positioned at least partially within an orifice defined by the bottom of the base 310.

[0052] With reference to FIG. 7, which provides a bottom perspective view of the outer assembly 200, the release member 220 may be configured to pivot relative to the connector 210. The release member 220 may pivot on an axis defined by the shaft 230. The shaft 230 may extend through both the release member 220 and the connector 210 in the transverse direction T. The release member 220 may define a release member opening 222. The connector 210 may define a connector opening 212. The connector opening 212 and the release member opening 222 may be aligned in the Z direction (FIG. 5). The release member 220, the shaft 230, or both, may comprise of a ferromagnetic material. For example, the release member 220, the shaft 230, or both, may comprise stainless steel. The connector 210 may comprise of a non-ferromagnetic material, such as plastic.

[0053] The connector 210 may include an outer assembly magnet 240. The outer assembly magnet 240 may be positioned at least partially within an orifice defined by the body of the connector 210. When the outer assembly 200 is removably coupled to the base assembly 300, the outer assembly magnet 240 may be positioned proximate to the second base magnet 350 of the base assembly 300. For example, the outer assembly magnet 240 may be aligned with the second base magnet 350 in the Z direction.

[0054] Referring back to FIG. 2, the release member 220 may be configured to pivot relative to the connector 210 from a first position to a second position. When the release member 220 is in the first position, as depicted, the protrusion 332 of the base 310 may be positioned at least partially interior to the release member opening 222. When the release member 220 is in the second position (not depicted), the protrusion 332 of the base 310 may be positioned exterior to the release member opening 222.

[0055] In operation, a user (e.g., a wearer of the helmet 10) may pivot the release member 220 from the first position to the second position, and vice versa. For example, a user may press down on the distal end of the release member 220 to pivot the release member opening 222 away from the protrusion 332 of the base 310. As previously mentioned, the first base magnet 340 may be positioned within the protrusion 332 of the base 310. Also, as mentioned, the release member 220 can be manufactured from a ferromagnetic material. As such, a magnetic force that attracts the release member 220 towards the first base magnet 340 that is within the protrusion 332 may be greater when the release member 220 is in the first position than when the release member 220 is in the second position. Therefore, when the release member 220 is in the first position, a first force may be required to decouple the outer assembly 200 from the base assembly 300. When the release member 220 is in the second position, a second force may be required to decouple the outer assembly 200 from the base assembly 300. The first force may be greater than the second force.

[0056] To decouple the outer assembly 200 from the base assembly 300, a user may press down on the distal end of the release member 220 to pivot the release member 220 from the first position to the second position. Then, a user may move the outer assembly 200 away from the base assembly 300 until the magnetic attraction between the first base magnet 340 and the release member 220 is insignificant.

[0057] The user may accomplish decoupling the outer assembly 200 from the base assembly 300 with one hand. For example, a user may use their thumb to press down on the release member 220 while also sliding the outer assembly 200 away from the flange 320 of the base 310 of the base assembly 300. Notably, the angle of the nub 333 of the protrusion 332 may allow for the release member 220 to more easily be slid above and over the protrusion 332 of the base 310.

[0058] Once the outer assembly 200 is decoupled from the base assembly 300, a user may recouple the outer assembly 200 to the base assembly 300. For example, a user may place the outer assembly 200 near and above the base assembly 300. The magnetic force between the various magnets within the buckle 100 (e.g., outer assembly magnet 240, first base magnet 340, and/or second base magnet 350) and the various components that are made from ferromagnetic material (e.g., the release member 220 and/or the shaft 230), may attract the outer assembly 200 to the base assembly 300 and couple the outer assembly 200 to the base assembly 300.

[0059] Notably, the ramped portion 334 of the nub 333 of the protrusion 332 and the ramped portion 322 of the flange 320 of the base 310 of the base assembly 300 may assist with correct positioning of the outer assembly 200 relative to the base assembly 300, when the outer assembly 200 is being coupled to the base assembly 300. For example, the ramped portion 334 of the nub 333 and the ramped portion 322 of the flange 320 may extend away from each other. As such, a deviation of the longitudinal alignment of the outer assembly 200 relative to the base assembly 300 may be automatically corrected because the outer assembly 200 may slide along the ramped portion 334 of the nub 333 and/or the ramped portion 322 of the flange 320 as the outer assembly 200 moves downward towards the base assembly 300.

[0060] The buckle 100 of the present disclosure has various benefits. For example, and as discussed, a user (e.g., a wearer of the helmet) may couple and decouple the buckle 100 with one hand. Further, a user may couple and decouple the buckle 100 with one hand and while wearing a glove, such as a safety glove.
