[0098] Referring generally to the accompanying drawings, several different embodiments of a helmet visor attachment system are illustrated. Helmets are used in a wide variety of construction work or other construction, residential, or commercial situations. In conventional visor attachment systems, the operator can pivot the visor away from the front of the user's face. However, pivoting the visor in this manner may interfere with the helmet brim and / or accessories attached to the front of the helmet, such as lights.

[0099] In contrast, the helmet system discussed in this paper utilizes an attachment structure that allows the face shield to slide / translate (e.g., substantially linearly) away from the user's face and to pivot upwards. This sliding and pivoting of the face shield avoids interference with the edges of the helmet and / or accessories attached to it.

[0100] refer to Figures 1 to 9 A helmet visor system for a safety helmet 12 is shown, which is illustrated as visor assembly 10. (See reference...) Figure 1The operator is shown wearing a safety helmet 12. As shown, the safety helmet 12 is oriented forward, with the brim 22 at the front end 50 of the safety helmet 12. The safety helmet 12 includes an outer shell 13 formed of a rigid material, such as a rigid polymer material. The safety helmet 12 (e.g., the outer shell 13 of the safety helmet 12) includes an outer surface 16 and an opposing inner surface 18, which defines a cavity 20 of the safety helmet 12, the size of which is determined to receive the wearer's head.

[0101] One or more first arms 26 are pivotally coupled to the helmet 12. The first arm 26 is pivotally rotatable relative to the helmet 12 about a first axis 24. In a particular embodiment, a mounting bracket 52 is detachably coupled to a rib 40 of the helmet 12, and the first arm 26 is indirectly coupled to the helmet 12 via a direct and pivotally coupled connection to the mounting bracket 52. In other words, the first arm 26 is pivotally coupled to the mounting bracket 52 such that the first arm 26 is coupled to the helmet 12 via the mounting bracket 52. In a particular embodiment, the ribs 40 of the helmet 12 extend circumferentially away from each other. In several different embodiments, the mounting bracket 52 is detachably coupled to the ribs 40. In a particular embodiment, the mounting bracket 52 is coupled to a mounting element and / or hole at the front end 50 of the helmet 12.

[0102] The second arm 28 is pivotally connected to each of the first arms 26. The second arm 28 is pivotally rotatable relative to the first arms 26 about a second axis 30 (e.g., not aligned with the first axis 34) that is different from the first axis 34. In a particular embodiment, two first arms 26 are pivotally connected to the helmet 12, two second arms 28 are connected to two first arms 26, and the face shield 32 is pivotally connected to two second arms 28. Figure 2 In several different embodiments, the second arm 28 is coupled to the central portion of the face shield 32. For example, the second arm 28 is coupled to the face shield 32 within 25% of the center of the face shield 32 (measured along the lateral and longitudinal axes of the face shield 32).

[0103] The face shield 32 is pivotally connected to (multiple) second arms 28. The face shield 32 is in the operating / lowered position... Figure 3 ) and the collapsed / raised position ( Figure 5 Actuation between ) when the face shield 32 is in the operating position ( Figure 3 When the face shield 32 is in the folded-up position, it is positioned in front of the wearer's face, such as below the brim of the hat. Figure 5 The face shield 32 is positioned above the front end 50 of the helmet 12, such as above the visor. In several different embodiments, when the face shield 32 is configured in an operating position on the wearer's head, the face shield 32 covers the wearer's eyes but not the wearer's mouth. Figure 1 In a particular embodiment, the second arm 28 includes a concave portion 36 when the face shield 32 is in the operating position. Figure 2 The concave portion 36 is curved relative to the first axis 24. In other words, when the face shield 32 is configured in the operating position, the concave portion 36 is concave relative to the wearer's head. The face shield 32 is pivotally rotatable relative to the second arm 28 about a third axis 34. In several different embodiments, the third axis 34 is different from the first axis 34 and the second axis 30.

[0104] In several different embodiments, the first and second sets of arms connect the face shield 32 to the helmet 12. Figure 1 In other words, the first arm 26 and the second arm 28 connect the face shield 32 to the helmet 12, and the third and fourth arms (e.g., another first arm 26 and second arm 28) also connect the face shield 32 to the helmet 12.

[0105] refer to Figures 3 to 5 This illustrates the method for moving the face shield 32 from the operating position ( Figure 3 Actuate to the stowed position ( Figure 5 An exemplary method is described. To rotate the face shield 32 from the operating position, the operator pivots one or more of the face shield 32, the second arm 28, and / or the first arm 26. The operator rotates the face shield 32 relative to the second arm 28 about a third axis 34 in direction 46, the operator rotates the second arm 28 relative to the first arm 26 about a second axis 30 in direction 44, and the operator rotates the first arm 26 relative to the helmet 12 about a first axis 24 in direction 42. The operator continues to rotate the first arm 26, the second arm 28, and / or the face shield 32 until the face shield 32 is in the retracted position. Figure 5 ).

[0106] refer to Figure 6 and Figure 7 This illustrates several different aspects of the face shield 32 that operates in cooperation with the helmet 12, including the brim 22. (Reference) Figure 6 When the face shield 32 is in the operating position, these arms extend and surround the brim 22.

[0107] refer to Figure 8 and Figure 9 This illustrates several different aspects of a face shield 32 that operates in conjunction with a helmet 62 without a brim. Helmet 62 is similar to helmet 12, except for the differences described, including the absence of a visor and / or a brim that is smaller in size compared to helmet 12. Reference Figure 8 When the face shield 32 is in the operating position, the first arm 26 remains vertical and / or nearly vertical, so that the face shield 32 is aligned with the front of the helmet 62.

[0108] refer to Figures 10 to 32 The diagram illustrates several different aspects of the face shield assembly 110. Aside from the differences described, the face shield assembly 110 is similar to the face shield assembly 10. An adjustable frame 122 is slidably and pivotally coupled to the helmet 112. The face shield 132 is coupled to the adjustable frame 122.

[0109] In a particular embodiment, a mounting bracket 124 is fixedly coupled to a helmet 112, and an adjustable frame 122 is slidably and pivotally coupled to the mounting bracket 124, and thus the adjustable frame 122 is coupled to the helmet 112 via the mounting bracket 124. In a particular embodiment, the adjustable frame 122 includes a plurality of arms 126 extending rearward from a front portion of the adjustable frame 122. Each arm 126 includes a first protrusion 128 and a second protrusion 130 rear of the first protrusion 128.

[0110] Mounting bracket 124 includes a plurality of slots 134 for receiving a first protrusion 128 and a second protrusion 130. Each slot 134 includes an upper portion 136 and a lower portion 138. As will be described in more detail below, when the face shield 132 is actuated between an operating position and a retracted position, the first protrusion 128 and the second protrusion 130 slide within the slot 134.

[0111] In a particular embodiment, mounting bracket 124 is coupled to rib 140. Ribs 140 extend upward from cap 152 and circumferentially away from each other. Figure 12 In a particular embodiment, when the mounting bracket 124 is attached to the rib 140, the rib 140 extends upward and away from the mounting bracket 124, thereby exposing a portion of the rib 140. The exposed portion of the rib 140 may be used to attach other accessories to the helmet 112 above the mounting bracket 124.

[0112] refer to Figures 13 to 20 This illustrates the method for moving the face shield 132 from the operating position ( Figure 13 Actuate to the stowed position ( Figure 19 An exemplary method.

[0113] Figure 14 Depicting when the face shield 132 is in Figure 13 The positions shown are the positions of the first protrusion 128 and the second protrusion 130 in the slot 134. When the face shield 132 is in the operating position ( Figure 13 The first protrusion 128 and the second protrusion 130 are located in the lower portion 138 of the slot 134. Figure 14 ).

[0114] Figure 16 Depicting when the face shield 132 is in Figure 15 The positions shown are those of the first protrusion 128 and the second protrusion 130 in the slot 134. When the operator slides the face shield 132 and the adjustable frame 122 along direction 142, the first protrusion 128 and the second protrusion 130 each slide towards the front of the lower portion 138. Figure 16 In one exemplary method of mating with the adjustable frame 122, the operator interacts with a mating element, shown as a tab 150, to pull the adjustable frame 122 in direction 142. The tab 150 facilitates adjustment of the face shield 132 with one hand without the operator touching the face shield 132, thereby protecting the face shield from smudges that can cause blurred vision.

[0115] Figure 18 Depicting when the face shield 132 is in Figure 17 The positions shown are those of the first protrusion 128 and the second protrusion 130 in the slot 134. When the operator rotates the face shield 132 and the adjustable frame 122 in direction 144, the first protrusion 128 slides into the front of the upper portion 136, and the second protrusion 130 slides into the middle of the lower portion 138. Figure 18 ).

[0116] Figure 20 Depicting when the face shield 132 is in Figure 19 The positions shown are those of the first protrusion 128 and the second protrusion 130 in the slot 134. This is the position when the operator continues to rotate the face shield 132 and the adjustable frame 122 along direction 144. Figure 19 The first protrusion 128 slides into the rear of the upper portion 136, and the second protrusion 130 slides into the rear of the lower portion 138. Figure 18 ).

[0117] Figures 21 to 32 Several different methods and structures that can be used to adjust the position of a face shield are described. This paper envisions that it is possible to utilize... Figures 21 to 32 The structures and / or methods described herein allow for minor adjustments to the position of the face shield. These minor adjustments allow for a more personalized fit to the operator's face, thus allowing the user to combine prescription glasses with the face shield.

Arms 324 are pivotally coupled to the mounting bracket 352, one or both arms 324 are pivotally coupled to a frame 348, and the frame 348 is coupled to the face shield 332. In a particular embodiment, the face shield assembly 310 includes two arms 324. A semi-transparent shield (shown as face shield 332) is coupled to the frame 348. The arms 324 are positioned relative to the mounting bracket 352 from a retracted position (…). Figure 57 Rotate to the operating position. Figure 61 When the face shield 332 pivots between the retracted position and the operating position, the configuration of the face shield assembly 310 helps the face shield 332 avoid the helmet brim and / or the headlamp of the helmet being worn by the user. Apart from the differences discussed herein, the face shield 332 is substantially the same as the face shield 32. In several different embodiments, the first arm 324 and the second arm 324 are each pivotally coupled to the mounting bracket 352 such that each of the first arm 324 and the second arm rotates about a first axis 330 relative to the mounting bracket 352.

[0131] In several different embodiments, one or both arms 324 include a convex portion 327 that is convex relative to the wearer's head when the face shield 332 is configured in the operating position. In other words, when the face shield 332 is configured in the operating position, the convex portion bends away from the wearer's head. Figure 60 ).

[0132] refer to Figures 62 to 68Several different aspects of the coupling mechanism of the face shield assembly 310 are shown. A first end 326 of arm 324 is pivotally coupled to a mounting bracket 352. A second end 328 of arm 324, opposite to the first end 326, is pivotally coupled to a frame 348. Arm 324 rotates relative to the mounting bracket 352 about a first axis 330, and arm 324 rotates relative to the frame 348 about a second axis 334. In other words, frame 348 is pivotally rotatable relative to each of the first and second arms 324 about a second axis 334. In several different embodiments, frame 348 is rigidly coupled to the face shield 332. In several different embodiments, and as will be explained, frame 348 is mechanically detachably coupled to the face shield 332.

[0133] refer to Figures 63 to 65 This illustrates several different aspects of the connection between the mounting bracket 352 and the arm 324. In several different embodiments, the mounting bracket 352 and / or the arm 324 include one or more pawls to bias the mounting bracket 352 and the arm 324 into a certain configuration relative to each other. In a particular embodiment, the mounting bracket 352 includes a pawl 350. A biasing element (shown as a spring 338) biases the mounting bracket 352 and the arm 324 to remain in place relative to each other even when the mounting bracket 352 and the arm 324 are in the pawl position. In a particular embodiment, the mounting bracket 352 and the arm 324 can move up to 260 degrees relative to each other. In a particular embodiment, the mounting bracket 352 and the arm 324 can be positioned between 25 and 40 degrees off-vertical (e.g., a face shield can be positioned between 25 and 40 degrees off-vertical).

[0134] refer to Figures 66 to 68 This illustrates several different aspects of the connection between frame 348 and arm 324. In several different embodiments, the mating between frame 348 and arm 324 creates a frictional engagement to bias frame 348 and arm 324 to hold them in place relative to each other. In a particular embodiment, frame 348 and arm 324 have a range of motion of 200 degrees relative to each other. In a particular embodiment, frame 348 and arm 324 can be positioned between 25 and 40 degrees off-vertical (e.g., a face shield can be positioned between 25 and 40 degrees off-vertical).

[0135] refer to Figures 69 to 73 The sliding lock 390 slidably engages with a helmet visor (such as a mounting bracket 352). The sliding lock 390 includes an inwardly extending protrusion 392 (e.g., toward the helmet). When the sliding lock 390 is in the locked position ( Figure 72The protrusion 392 engages with the retention feature 314 on the helmet to secure the mounting bracket 352 to the helmet. In a particular embodiment, the mounting bracket 352 is attached to the helmet at a front position and above the brim. In a particular embodiment, a recess 360 engages with a protrusion above the brim on the front of the helmet to attach the mounting bracket 352 to the helmet. To attach the mounting bracket 352 to the helmet, the mounting bracket 352 is positioned at the front of the helmet and above the front brim, and the mounting bracket 352 slides downward such that the recess 360 engages with the protrusion on the helmet. When the sliding lock 390 is in the unlocked position ( Figure 73 The protrusion does not mate with the retention feature 314, and therefore the mounting bracket 352 can be more easily removed from the helmet. (See reference) Figure 70 The sliding lock 390 can be attached to and detached from the mounting bracket 352, for example, by engaging and disengaging the sliding lock 390 with the mounting bracket 352.

[0136] refer to Figures 74 to 76 In several different embodiments, the face shield 332 can be removed from the frame 348 and replaced with a new face shield 333. The user engages with the attachment mechanism 394 of the face shield 332 to remove the face shield 332 from the attachment mechanism 396 of the frame 348. Figure 75 Then, the user attaches the new face shield 333 to the frame 348. Figure 76 ).

[0137] refer to Figures 77 to 81 This illustrates several different aspects of the face shield assembly 410. Aside from the differences discussed herein, the face shield assembly 410 is substantially the same as the face shield assembly 310. In particular, the support structure inside the arm 424 includes a different cross-shading configuration.

[0138] The face shield 410 includes a mounting bracket 452 attached to the helmet. One or more arms 424 (e.g., two arms 424) are pivotally coupled to the mounting bracket 452, and a frame 448 is pivotally coupled to the one or more arms 424. The face shield 432 is coupled to the frame 448. A sliding lock 490 is slidably engaged with the mounting bracket 452. (Reference) Figure 81 The sliding lock 490 includes a protrusion 492 that extends inward toward the safety helmet to which the mounting bracket 452 is attached.

[0139] refer to Figures 82 to 85 This illustrates several different aspects of the face shield assembly 510. Aside from the differences discussed herein, the face shield assembly 510 is substantially the same as the face shield assembly 410. The arm 524 of the face shield 510 has a less pronounced bend compared to the arm 424 of the face shield 410.

[0140] refer to Figures 86 to 89 This illustrates several different aspects of a protective system for safety headgear. The protective system includes a slider that locks the visor guard to the safety headgear. The slider is in the locked position (…). Figure 87 ) and unlock location ( Figure 88 Actuation occurs between the sliding element and the protrusion extending from the safety headgear. Figure 89 ).

[0141] In several different embodiments, the helmet system 601 includes a helmet, a visor 610, and a locking mechanism. The visor 610 is functionally similar to... Figures 69 to 73 The brim protector and locking mechanism shown are in addition to those described herein.

[0142] The visor 610 is detachably attached to the helmet 602 such that the front of the visor 610 is positioned at the front 604 of the helmet 602. The visor includes a visor 632 extending radially outward from the center of the helmet 602.

[0143] In several different embodiments, a face shield (e.g., face shield 32) is detachably attached to a brim protector 610. The face shield is movable between a lowered position and an raised position, such that when the face shield is in the lowered position, it is positioned below the brim protector 610, and when the face shield is in the raised position, it is positioned above the brim protector 610.

[0144] The locking mechanism 620 is coupled to the visor guard 610, for example, in a slidable manner. The locking mechanism 620 is configured to be in the locked position ( Figures 86 to 87 ) and unlock location ( Figure 88 The locking mechanism 620 is actuated between the two positions. When the locking mechanism 620 is in the locked position, it prevents the visor guard 610 from sliding vertically relative to the helmet. The locking mechanism 620 slides along the horizontal axis 622 when changing between the locked and unlocked positions.

[0145] Apart from the differences described, helmet 602 is similar to helmet 12 or helmet 62. In a particular embodiment, helmet 602 includes a protrusion 603 extending forward at the front portion 604 of helmet 602. When locking mechanism 620 is in the locked position, locking mechanism 620 abuts against the lower surface 605 of protrusion 603.

[0146] In several different embodiments, the locking mechanism 620 abuts against a protrusion 603 extending from the mounting element 606 of the helmet 602. In several different embodiments, the helmet 602 includes a mounting element 606 extending from the front 604 of the helmet 602. The mounting element 606 includes opposing ridges 607 extending away from each other, and a visor 610 is coupled to the helmet 602 via the mounting element 606. For example, the visor 610 includes a first lateral wall 614 and a second lateral wall 616, with the opposing ridge 607 of the mounting element 606 coupled to the first lateral wall 614 and the second lateral wall 616 of the visor 610. In several different embodiments, the visor 632 extends horizontally from the helmet. In several different embodiments, each of the first lateral wall 614 and the second lateral wall 616 extends upward from the visor 632 and extends circumferentially around the front of the wearer's head.

[0147] refer to Figures 90 to 99 This illustrates several different aspects of the face shield assembly 710. Apart from the differences discussed herein, the face shield assembly 710 is substantially the same as face shield assemblies 210, 310, 410, or 510. In particular, the arm 724 of the face shield 710 has a slightly different shape than the arms of other face shields (e.g., the arm 724 is linear when viewed from the side, but concave relative to the wearer's head when viewed from the front).

[0148] Arm 724 extends from a first end 726 to an opposite second end 728. A face shield 732 is coupled (e.g., pivotally coupled) to arm 724 such that the face shield 732 rotates relative to arm 724 about a first axis 730. In several different embodiments, the face shield 732 is coupled to arm 724 via frame 736, which is rigidly coupled to a portion of the periphery of the face shield 732. Arm 724 is coupled to helmet 712, for example, via mounting bracket 722. Mounting bracket 722 is substantially identical to mounting bracket 222, except for the differences discussed herein. In several different embodiments, arm 724 is pivotally coupled to mounting bracket 722 such that arm 724 rotates relative to mounting bracket 222 and / or helmet 712 about a second axis 734.

[0149] refer to Figures 91 to 92 The diagram illustrates several different aspects of the arm 724 coupled to the mounting bracket 722. In several different embodiments, a locking arm 790 extends from the arm 724 into a bore 794 in the mounting bracket 722. The locking arm 790 is outwardly biased to retain coupling to the bore 794 by a plug 792 inserted between the locking arms 790 to radially bias the locking arm away from the plug 792, thereby securing the engagement between the arm 724 and the mounting bracket 722.

[0150] refer to Figures 93 to 97 This illustrates several different aspects of the arm 724 coupled to the mounting bracket 722. In several different embodiments, the mounting bracket 722 includes a coupling member 740 that couples the mounting bracket 722 to the arm 724. The arm 724 includes a protrusion 796 that abuts along the outer surface 742 of the coupling member 740. The abutment between the protrusion 796 of the arm 724 and the coupling member 740 facilitates various configurations in which the arm 724 is oriented relative to the mounting bracket 722. For example, once a user orients the face mask 732 in a desired position (e.g., the face mask 732 is completely in front of their face, the face mask 732 is partially in front of their face, or the face mask 732 is above their face), the frictional engagement between the protrusion 796 of the arm 724 and the coupling member 740 biases the arm 724 to remain stationary relative to the mounting bracket 722.

[0151] A protrusion 796 of arm 724 abuts against outer surface 742 along range 744 from a first end 746 to a second end 748 of range 744. Outer surface 742 includes one or more protrusions 750 extending radially away from axis 730. Protrusions 750 are configured to bias the protrusions of arm 724 toward either the first end 746 or the second end 748 of range 744.

[0152] The connecting member 740 defines one or more recesses (shown as a first hole 752 and a second hole 753). In several different embodiments, the first hole 752 and / or the second hole 753 extend circumferentially about the connecting member relative to axis 130. A range 744 extends along a first unsupported portion 754, a supported portion 756, and a second unsupported portion 758. The first unsupported portion 754 is the portion of range 744 radially aligned with axis 730 and the first hole 752, the second unsupported portion 758 is the portion of range 744 radially aligned with the second hole 753, and the supported portion 756 is circumferentially located between the first unsupported portion 754 and the second unsupported portion 758 relative to axis 130.

[0153] The first hole 752 is configured to allow the first unsupported portion 754 of the outer surface 742 to deform more than the supported portion 756 when the protrusion 796 of the arm 724 abuts against the first unsupported portion 754. In this way, the first unsupported portion 754 and the second unsupported portion 758 are configured to act like a leaf spring by applying a radially outward force to the protrusion 796 relative to the axis 130. The applicant has observed that allowing the first unsupported portion 754 to deform more than the supported portion 756 helps protect the first unsupported portion 754 from damage during use. For example, in use, a worker typically aligns the protrusion 796 of the arm 724 with the second unsupported portion 758 (when the face shield 732 is in front of the worker's face) or the first unsupported portion 754 (when the face shield 732 is above the worker's face). Therefore, those portions of the range 744 most frequently abut against the protrusion 796 of the arm 724. By allowing the first unsupported portion 754 and the second unsupported portion 758 to deform more easily than the supported portion 756, the corresponding outer surfaces 742 of those portions of range 744 are less likely to be damaged during long-term use.

[0154] refer to Figure 97 The first unsupported portion 754 defines a radius 755 extending from the axis 730, the supported portion 756 defines a radius 757 extending from the axis 730, and the second unsupported portion 758 defines a radius 759 extending from the axis 730. In several different embodiments, the radius 755 and / or the radius 759 is longer than the radius 757.

[0155] In several different alternative embodiments, arm 724 includes a coupling member and mounting bracket 722 includes a protrusion that mates with the coupling member of arm 724.

[0156] refer to Figures 98 to 99 This illustrates several different aspects of the engagement between frame 736 and arm 724. Specifically, frame 736 includes a coupling member 780 that pivotally connects frame 736 to arm 724. Aside from the differences discussed herein, coupling member 780 is substantially identical to coupling member 740. Specifically, coupling member 780 extends from frame 736 and is configured to engage with a protrusion 798 extending from arm 724. Similar to coupling member 740, coupling member 780 includes one or more holes 782 configured to allow deformation of coupling member 780 when the protrusion engages with a portion of coupling member 740 radially aligned with a corresponding hole 782.
