Description

TECHNICAL FIELD

[0001] Example embodiments of the present disclosure relate generally to a helmet, and more particularly to a safety helmet. BACKGROUND

[0002] Industrial safety helmets are critical to protecting workers from head injuries in dangerous environments such as construction sites, manufacturing plants, and other industrial settings. These helmets are designed to protect against impacts, falling objects, electrical shock, and other potential hazards. A key component of many modern industrial helmets is eyewear, which provides additional protection for the face and eyes. However, current eyewear integrated into these helmets is often complex, making it cumbersome for users. Metal parts such as screws can interfere with the ability of the helmet to meet electrical safety requirements. Additionally, users find it challenging to remove or move the lenses (e.g., pivot the lenses away from and towards a position in front of the user’s eyes), which limits the flexibility and usability of the helmet in dynamic work environments.

[0003] The inventors have found many deficiencies and problems in the prior art and practice that are the subject of the embodiments described herein. Through effort, ingenuity, and innovation, many of these deficiencies and problems have been addressed by the development of solutions included in the embodiments of the present disclosure, some examples of which are described in detail herein. SUMMARY

[0004] A brief summary of some example embodiments is presented below to provide a basic understanding of some aspects of the present disclosure. This summary is not an extensive overview, and is neither intended to identify key or critical elements nor to delineate the scope of the disclosure. It is also to be understood that the scope of the present disclosure includes many potential embodiments in addition to those presented below, some examples of which will be further described in the detailed description presented later.

[0005] In an example embodiment, a safety helmet is disclosed. The safety helmet includes a shell defining a rim and including a pocket, and an adapter assembly including a shell adapter positioned within the pocket of the shell, the shell adapter including a bore, a lens adapter including a body defining a bore, a hook extending from the body and positioned on the rim of the shell, a curved slot extending in a circumferential direction around the bore, a tab, and a connector positioned within the bore of the shell adapter and the bore of the lens adapter. Further, the shell is positioned between the shell adapter and the lens adapter; the safety helmet also includes a lens including a lens wheel at an end of the lens. Further, the lens wheel is positioned within the curved slot of the lens adapter and is removably snapped by the tab. Further, the curved slot of the lens adapter is configured to allow the lens to move from a first position to a second position when a force of a sufficient magnitude is applied to the lens and to prevent the lens from moving from the first position to the second position when a force of an insufficient magnitude is applied to the lens.

[0006] In some embodiments, the shell also includes an inner portion and an outer portion. Further, the pocket is made at the inner portion of the shell to receive the shell adapter. In some embodiments, the lens adapter is configured to be positioned at the outer portion of the shell to receive the lens wheel of the lens.

[0007] In some embodiments, the shell also defines an aperture on each side of the shell. Further, the bore of the shell adapter, the bore of the lens adapter, and the aperture of the shell overlap one another such that the connector passes through the bore of the shell adapter, the bore of the lens adapter, and the aperture.

[0008] In some embodiments, the curved slot includes one or more notches and the lens wheel includes one or more protrusions at an outer periphery of the lens wheel. In some embodiments, each of the one or more notches is adapted to receive at least one of the one or more protrusions. In some embodiments, rotational movement of the lens wheel within the curved slot facilitates the one or more protrusions to be seated within the one or more notches to prevent the lens from moving from the first position to the second position when a force of an insufficient magnitude is applied to the lens.

[0009] In some embodiments, the lens wheel also includes one or more stop ribs. Further, the curved slot is configured to block movement of the one or more stop ribs and thereby prevent the lens from moving beyond the first position or the second position.

[0010] In some embodiments, the first position corresponds to a closed position of the lens and the second position corresponds to an open position of the lens.

[0011] In some embodiments, the tab is adapted to be pressed by a user to release the lens wheel from the curved slot and to detach the lens from the shell.

[0012] In another example embodiment, a method is disclosed. The method includes positioning a shell adapter of an adapter assembly within a pocket of a shell. Further, the shell adapter includes a hole; the method also includes positioning a hook extending from a body of a lens adapter of the adapter assembly on a rim of the shell. Further, the lens adapter includes a curved slot extending in a circumferential direction around the hole and a tab; the method also includes positioning a connector within the hole of the shell adapter and the hole of the lens adapter. Further, the shell is positioned between the shell adapter and the lens adapter; and the method also includes positioning a lens wheel positioned at an end of a lens within the curved slot of the lens adapter and removably snapping the lens wheel with the tab. Further, the curved slot of the lens adapter is configured to allow the lens to move from a first position to a second position when a force of a sufficient size is applied to the lens and prevent the lens from moving from the first position to the second position when the force applied to the lens is not of a sufficient size.

[0057] Figure 5AThe figure shows a side view of an adapter assembly 104 according to an example embodiment of the present disclosure, illustrating the rotation of the lens wheel 132. Figures 5B-5D The illustration shows the movement of a lens 106 from a first position 502 to a second position 506 according to an example embodiment of the present disclosure.

[0058] In some embodiments, each lens wheel 132 of the lens 106 may define a circumferential direction 500 about a rotation axis. In some embodiments, each lens wheel 132 may be configured to rotate in both clockwise and counterclockwise directions. In some embodiments, a curved groove 128 of each lens adapter 114 may allow the lens 106 to move from a first position 502 to a second position 506. In some embodiments, each lens wheel 132 may be configured to rotate about a rotation axis in a circumferential direction 500 to allow the lens 106 to move from the first position 502 to the second position 506 and vice versa.

[0059] like Figure 5B As illustrated, the curved groove 128 of the lens adapter 114 may include one or more recesses 504. Furthermore, the one or more recesses 504 may be carefully formed on the inner periphery of the curved groove 128. In some embodiments, the one or more recesses 504 may be carefully formed by various machining processes such as cutting, grinding, etc. In some embodiments, the one or more recesses 504 may be configured to have various shapes. These shapes may include, but are not limited to, semicircular, chamfered, elliptical, etc. In some embodiments, each lens wheel 132 may include one or more protrusions 404. In some embodiments, the one or more protrusions 404 may be carefully formed on the outer periphery of the lens wheel 132. In some embodiments, these one or more protrusions may define various shapes. These shapes may include, but are not limited to, semicircular, chamfered, elliptical, etc. In some embodiments, the one or more recesses 504 of the curved groove 128 may be adapted to receive at least one of the one or more protrusions 404 of each lens wheel 132. In some embodiments, the rotational movement of the lens wheel 132 within the bending groove 128 can facilitate the placement of one or more protrusions 404 of each lens wheel 132 within one or more recesses 504 of the bending groove 128 to lock the movement of the lens 106 at a first position 502 or a second position 506 (e.g., preventing the lens 106 from moving from the first position 502 to the second position 506 when the force applied to the lens 106 is insufficient).

[0060] In some embodiments, when the lens 106 of the safety helmet 100 is positioned at a first position 502, at least one protrusion of one or more protrusions 404 of the lens wheel 132 may be disposed in at least one recess of one or more notches 504 of the bending groove 128 of the lens adapter 114. In one case, when a user applies a sufficient force to the lens 106 to move the lens 106 from the first position 502 to a second position 506, the lens wheel 132 of the lens 106 may rotate about a rotation axis in the circumferential direction 500. Furthermore, at least one protrusion of one or more protrusions 404 may pop out from at least one recess of one or more notches 504, such as... Figure 5C As illustrated in the figure. In various examples, the lens wheel 132 can move in the circumferential direction 500 when the at least one protrusion pops out of the at least one recess. In some embodiments, when the lens 106 of the safety helmet 100 reaches the second position 506, another protrusion of one or more protrusions 404 of the lens wheel 132 can be positioned into another recess of one or more recesses 504 of the curved groove 128 of the lens adapter 114 to lock the movement of the lens wheel 132.

[0061] like Figure 5D As illustrated, when the visor 106 of the safety helmet 100 is positioned at the second position 506, one of the protrusions 404 of the visor wheel 132 can be positioned into another recess in one or more notches 504 of the curved groove 128 of the visor adapter 114. In another scenario, when the user applies sufficient force to the visor 106 to move it from the second position 506 to the first position 502, the visor wheel 132 of the visor 106 can rotate about its axis of rotation in the circumferential direction 500. Furthermore, the other protrusion 404 can pop out of the other recess in one or more notches 504. In various examples, when the other protrusion pops out of the other recess, the visor wheel 132 can move about its axis of rotation in the circumferential direction 500. In some embodiments, when the lens 106 of the safety helmet 100 reaches the first position 502, at least one of the protrusions 404 of one or more of the lens wheel 132 can be placed into at least one of the recesses 504 of one or more of the bending groove 128 of the lens adapter 114 to lock the movement of the lens wheel 132.

[0062] In some embodiments, each lens wheel 132 may further include one or more stop ribs 406. In some embodiments, the one or more stop ribs 406 of each lens wheel 132 may be integral with the outer periphery of each lens wheel 132. In some embodiments, each of the one or more stop ribs 406 may be configured to move angularly with the movement of the corresponding lens wheel 132. In some embodiments, the one or more stop ribs 406 may be configured to be blocked by a curved groove 128 of the lens adapter 114. In some embodiments, the curved groove 128 may be configured to block the movement of the one or more stop ribs 406, which facilitates locking the movement of the lens 106 between a first position 502 and a second position 506 (e.g., preventing the lens 106 from moving beyond the second position 506 or the first position 502).

[0063] For example, one or more stop ribs 406 may include a first stop rib and a second stop rib. When the lens 106 is positioned at the first position 502, the first stop rib may be configured to be blocked by the bending groove 128. Furthermore, when the lens 106 is positioned at the second position 506, the second stop rib may be configured to be blocked by the bending groove 128.

[0064] In some embodiments, a method of using a safety helmet 100 is disclosed. The method may include one or more operations for attaching an adapter assembly 104 and a lens 106 to the safety helmet 100. In one operation, a housing adapter 112 of the adapter assembly 104 may be positioned within a cavity 200 of the housing 102. Furthermore, the housing 102 may also include an inner portion 204 and an outer portion 108. Additionally, the cavity 200 may be formed at the inner portion 204 of the housing 102 to receive the housing adapter 112. Furthermore, the housing adapter 112 may include a hole 120. In another operation, a hook 126 extending from the body 122 of the lens adapter 114 of the adapter assembly 104 may be positioned on an edge 202 of the housing 102. Furthermore, the lens adapter 114 may include a curved groove 128 that may extend circumferentially around the hole 120, and a tab 130. In another operation, a connector 116 may be positioned within the hole 120 of the housing adapter 112 and the hole 124 of the lens adapter 114. In addition, the shell 102 of the safety helmet 100 can be positioned between the shell adapter 112 and the lens adapter 114.

[0065] In another operation, the lens wheel 132 at the end of the lens 106 can be positioned within the bending groove 128 of the lens adapter 114. In another operation, the tab 130 can be configured to removably engage the lens wheel 132 of the lens. Furthermore, the bending groove 128 of the lens adapter 114 can be configured to: allow the lens 106 to move from a first position 502 to a second position 506 and vice versa when a sufficient force is applied to the lens 106; and prevent the lens 106 from moving from the first position 502 to the second position 506 and vice versa when the force applied to the lens 106 is insufficient. Furthermore, the first position 502 corresponds to the closed position of the lens 106, and the second position 506 corresponds to the open position of the lens 106. In some embodiments, the tab 130 can be adapted to be pressed by a user to release the lens wheel 132 from the bending groove 128 and detach the lens 106 from the housing 102.

[0066] This disclosure simplifies the easy assembly of the lens 106 with the safety helmet 100 via adapter assembly 104. Embodiments of this disclosure eliminate the need for metal parts such as screws in the safety helmet 100, thus preventing any electrical interference.
