[0052] FIG. 2 is a rear perspective sketch of the Headgear Assembly 1, as it would look in a closed, restrictive or protective position, showing both attached peripheral devices including a Shield 2.1 and a Mask 2.2. As can be seen, both peripheral devices are connected together within the Headgear Assembly 1. The entire Headgear Assembly 1 is constructed from, but not limited to, plastic such as ABS.
[0053] FIG. 3 is an illustration of the Headgear Assembly 1, as it would look in a neutral, relaxed, open or non-protective position, showing both attached peripheral devices including a Shield 2.1 and a Mask 2.2. This shows the outer most limit that the Shield 2.1 travels completely revealing the face, and the furthest the Mask 2.2 will travel completely exposing the nose and mouth. As can be seen, both peripheral devices are connected together within the Headgear Assembly 1.
[0054] The Headband 10, displayed in FIG. 4, is the main backbone of the Headgear Assembly 1, is semi-circular in overall structure and has numerous features which facilitate the functionality of the Headgear Assembly 1, including a curved rear portion which conforms to the circular structure of the human head and allows the headband to sit comfortably against the back of the head. The curved rear portion continues forward on both sides of the head where each side further divides in the horizontal plane, just prior to the back of the ears, into 2 hands; the Outer Hands 10.5 are parallel to each other and continue projecting forward, to complete the overall semi-circular structure of the Headband 10, and two Inner Hands 10.2 which are thinner and semi-flexible and project, slightly inward towards each other and away from the Outer Hands 10.5, and up to the perimeter of the formed semi-circular structure.
[0055] Referring back to FIG. 4, the Inner Hands 10.2 functions to hold the Headband 10 in place by, applying sufficient pressure to the both sides of the head and seating itself on top of both ears. In addition the Inner Hands 10.2 each have Ear Adapter Channels 10.3 which allow for the insertion of Ear Adapters 11 as shown in FIG. 5A-B that sit on the ears and further allows the Headband 10 to be raised if necessary, and moved forward or backward by the Ear Adapters 11 positioning within the Ear Channels 10.3.
[0056] Referring to FIG. 4, both Outer Hands 10.5 are positioned on the outside of the Inner Hands 10.2, are parallel to each other, and are thicker and rectangular in shape as compared to the Inner Hands 10.2, making them sturdier, as they support both the Face Shield 20 and the Face Mask 30. Both Outer Hands 10.5 project outward past the ears to complete the semi-circular structure of the Headband 10, and as shown in FIG. 6B, and allow the Shield Knob 21 and the Mask Arm 31 to connect to it and be secured by a Bolt 22 and Nut 23.
[0057] Referring back to FIG. 4, the Outer Hands 10.5 each have a circular Socket Port 10.6, into which the Shield Knob Axle 21.7 inserts and is attached to the Outer Hand 10.5 as illustrated in FIG. 6B, and a Shield Guide Rod 21.6 which inserts into the Shield Knob Channel 21.2 as shown in FIG. 6C and functions to restrict the range of rotation of the Face Shield as illustrated in FIG. 6D.
[0058] Referring back to FIG. 4, at both points where the Headband 10 divides into the Outer Hands 10.5 and the Inner Hands 10.2, there exists on the outward facing surface, a pair of Mask Hangers 10.1 which facilitate an option to attach the Mask Cords 2.2.1 in the configuration where the Headgear Assembly 1 is configured with the Face Shield 20 only as shown in FIG. 14. This relieves the ears from having to hold the Mask Cords 2.2.1 and provides extended comfort in wearing the Mask 2.2.1.
[0059] FIG. 5A is a sketch of one of the two identical Ear Adapter 11 which can be used, if necessary, to vary the position of Headgear Assembly 1 on the wearer's head. Its features include the Ear Seat 11.1 which rests behind the ear, the two Ear Guides 11.2 which allows the Ear Adapter 11 to slide along the Inner Hand 10.2 as shown in the exploded view FIG. 5B, and the Channel Knob 11.3 which keeps the Ear Adapter 11 in place in the Ear Adapter Channel 10.3. FIG. 5B shows that the Ear Adapter 11 can be positioned anywhere along the Ear Adapter Channel 10.3 in the Headgear Assembly 1 providing vertical and horizontal adjustments for different sized heads. Each Head Assembly 1 utilizes 2 identical Ear Adapters 11 for the said purpose, one on each Inner Hand 10.2.
[0060] Referring back to FIG. 1 the Face Shield 20 is attached to the Headband 10 via the Shield Knob 21 and comprises of a pair of Shield Knobs 21 and the Shield Frame 24.
[0061] Both Shield Knobs 21 are mirror images of each other, and as shown in FIG. 6A, comprises two main sections namely the Shield Knob Hand 21.3 whose function is to connect the Shield Frame 24 to the Shield Knob 21, and the Shield Knob Base 21.1 which functions to attach the Face Shield 21 to the Headband 10.
[0062] Referring to FIG. 6A the Shield Knob Hand 21.3 has a hollow rectangular structure with an open entrance on one end, the Shield Arm Port 21.5, into which the Shield Arms 24.1 insert, and multiple Shield Knob Position Ports 21.4 along its inward facing surface which receive the Shield Arm Latch 24.2 and so facilitates multiple distancing of the shield Frame 24 from the wearer's face.
[0063] Referring back to FIG. 6A, the Shield Knobs 21 also possess a circular base, the Shield Knob Base 21.1, at the other end of the Shield Knob Hand 21.3. The Shield Knob Base 21.1 has at its center the Shield Knob Axle 21.7 which has a hole going straight through to its outer surface for receiving the Bolt 22 as shown in FIG. 6B, and a Shield Knob Channel 21.2 which receives the Shield Guide Rod 10.4 as shown in FIG. 6C.
[0064] FIG. 6C illustrates the positioning of the Shield Guide Rod 10.4 in the Shield Knob Channel 21.2 which limits the range of rotation of the Face Shield 20 to about 120 degrees from vertical and allows the Face Shield 20 to remain stationary in 5 different positions, as shown in FIG. 6D, by utilizing the multiple Position Tabs 21.6 which reduces the width of the Shield Knob Channel 21.2 and keeps the Shield Arms 24.1 in place.
[0065] In FIG. 7A, the Shield Frame 24 is attached to the Shield Knobs 21 by inserting the Shield Arms 24.1 into the Shield Arm Port 21.5 until the Shield Latch 24.2 is positioned in one of the available Shield Knob Position Ports 21.4, as shown in FIG. 6C, which positions the Shield 2.1 further from or closer to the wearer's face, and shown in FIG. 7B is a top view of the Shield Frame 24 highlighting its features including its two Shield Latch 24.2, two Shield Terminators 24.3 which secures the Shield 2.1 extending beyond the Shield Channel 24.6 and wraps the Shield 2.1 around the Shield Frame 24, and the two Shield Arms 24.1 which are joined by the Shield Curve 24.7.
[0066] FIG. 8A is a bottom perspective view of Shield Frame 24 illustrating the features of the Shield Frame 24 which allows the Shield 2.1 to be easily inserted and secured in the Shield Channel 24.6. This is accomplished by the three Shield Buttons 24.4 which are proportionally spaced along the Shield Curve 24.7 and possessing a tapered top surface that allows the Shield 2.2 to easily slide into the Shield Channel 24.6.
[0067] Referring again to FIG. 8A, accompanying the Shield Buttons 24.4 are the three Shield Button Gaps 24.5 perfectly aligned with the Shield Buttons 24.4 which project inward across the Shield Channel 24.6 and terminating within the Shield Button Gaps 24.5; Once the Shield 2.1 is fully inserted into the Shield Channel 24.6, the Shield Buttons 24.4 pass through the respective Shield Holes 2.1.1, shown in FIG. 8B, and secure the Shield 2.1 in place as previously shown in FIG. 2.
[0068] Referring back to FIG. 1, the Face Mask 30 is attached to the Headband 10 via the Mask Arm 31. As shown in FIG. 5B, it can be seen how the Mask Arm Cavity 31.4 is securely positioned over the headband's Outer Arm 10.5. The cross sectional view, shown in FIG. 6B further illustrates how the Mask Arm 31 is positioned on the headband's Outer Arm 10.5 and secured with a Bolt 22 and Nut 23.
[0069] FIG. 9A is an exploded view of the Face Mask 30 and illustrates the two Mask Arms 31 position and relationship to the other face mask parts. Both Mask Arms 31 are identical mirror images of each other where the upper part of the Mask Arm 31 is the open ended Mask Arm Cavity 31.4, illustrated in FIG. 9B-C, whose purpose is for securing the Mask Hand 31 to the Outer Hand 10.5. Also visible within the Mask Arm Cavity 31.4, and residing on the inside center of its vertical surface is a Circular Protrusion 31.5 that fits snugly into the headband's Socket Port 10.6, and has a through hole for facilitating a Nut 22.
[0070] Referring back to FIG. 6B, the upper part of the Mask Arms 31 also have on its inner facing surface the Upper Cord Guide 31.1. The Upper Cord Guide 31.1 functions to hold the Mask Cord 2.2.1, mimicking the Mask Cord 2.2.1 going over the ear, and with the Lower Cord Guide 32.4, always maintains the shape of the Mask 2.2 as it appears when attached to a person's face.
[0071] As shown in FIG. 9B and FIG. 9C each Mask Arm 31 extends down and has at its base the Mask Arm Hole 31.3 and the Mask Hand Guide Knob 31.2. Illustrated in FIG. 9A, the Mask Arm Hole 31.3 receives the Mask Plug 34 which secures the Mask Hand 32 and the Mask Control Knob 33 to the Mask Arm 31.
[0072] FIG. 10A illustrates the Mask Control Knob 33 whose primary function is to control the displacement of the Mask 2.2 from the wearer's face. At its center is the recessed Mask Knob Socket 33.2 into which the Mask Plug 34 inserts to hold the Mask Hands 32 to the Mask Arms 31 as shown previously in FIG. 9A. In addition the Mask Control Knob 33 has a teethed interface, the Mask Knob Teeth 33.1, surrounding the Mask Knob Socket 33.2, which is used in moving the Mask Hand 32
[0073] FIG. 10C and FIG. 10D illustrates the Mask Hand 32 which connects the Mask Arm 31 to the Mask Frame 35 and enables the Mask 2.2 to move with and when the Mask Hand 32 moves; as shown in, the top front perspective view of the Mask Hand 32, FIG. 10D, is the Mask Hand Teeth 32.2, which runs along the inside top of the hollowed outer surface 32.5, and the Mask Hand Channel 32.1, which runs alongside and below the Mask Hand Teeth 32.2, and completely perforates the Mask Hand 32. In addition it should be noted the unique shape of the Mask Hand 32, whose rear vertical design, facilitates a downward motion of the attached Mask Frame 35 after the moving it forward, FIG. 10B, and the upward motion of the Mask Frame 35 prior to moving the Mask Hand 32 backward, FIG. 10C.
[0074] Referring back to FIG. 10B-C, the forward and down motion of the Mask Hand 32, is initiated by rotating the Mask Control Knobs 33 forward as illustrated by direction arrow B, and the upward and back movement of the Mask Hand 32 is initiated by rotating the Mask Control Knobs 33 backward as illustrated by directional arrow D. This respectively moves the Mask 2.2 away from the face and then down to clear the nose and mouth, and then reverses the process to place the Mask 2.2 back over the nose and mouth. It should be noted that the Mask Hand Guide Knob 31.2, sits within the Mask Hand Channel 32.1 as shown in FIG. 11, and forces the Mask Hand 32 to only move in a singular direction.
[0075] Referring to FIG. 10E, the Lower Cord Guide 32.4 is situated at the rear base of the inward facing surface of the Mask Hand 32. Further illustrated in FIG. 11, it functions to hold the Mask Cord 2.2.1, mimicking the Mask Cord 2.2.1 being seated on the lower curve of the wearer's ear. Once the Mask Cords 2.2.1 wrap around the Lower Cord Guide 32.4 and the Upper Cord Guide 31.1 on each side of the Face Mask 30, the Mask 2.2 will be in the position as it would normally be when on a wearer's face with the Mask Cords 2.2.1 around both ears; and because the two cord guides moves synchronously with each other, the arrangement holds and maintains the tension of the Mask Cord 2.2.1 consistently, regardless of the displacement of the Mask 2.2 to the face.
[0076] Each Mask Hand 32 has an additional feature, the Mask Hand Ports 32.3, as shown in FIG. 10D-E, whose function is to receive and securely hold the Mask Frame 35 in position as shown in FIG. 11. The Mask Hand Ports 32.3 are equally spaced vertically along the front face of the Mask Hand 32 and allows for multiple vertical height placement of the Mask Frame 35.
[0077] FIG. 12A illustrates the curved Mask Frame 35 which is positioned on the outside of the Mask 2.2, and fitted on each side into one of the Mask Hand Ports 32.3 of the Upper Hand 32 as shown in FIG. 11.
[0078] Illustrated in FIG. 12A-C, the Mask Frame 35 is wider at its center forming the Mask Sealer 35.2 from which extends a protrusion, positioned at its center on its inward facing surface, the Mask Frame Prod 35.1. The Mask Frame Prod 35.1 is inserted through an incision, about 4 mm in diameter, made in the center of the Mask 2.2. The Mask Incision Plug 36 is then place on the inside of the Mask 2.2, and over the Mask Frame Prod 35.1, in order to secure the Mask 2.2 to the Mask Frame 35, and to seal the incision made in the Mask 2.2.

[0080] The Shield 2.1 is first inserted into the Shield Channel 24.6 by aligning its three holes 2.1.1 with the three Shield Buttons 24.4 and pushing the Shield 2.1 down into the Shield Channel 24.6 until the Shield Buttons 24.4 are positioned in the Shield Holes 2.1.1 as shown in FIG. 2.
[0081] A small horizontal incision is made in the center of the Mask 2.2. Fit the Mask 2.2 inside the Mask Frame 35 by inserting the Mask Frame Prod 35.1 from the outward surface of the Mask 2.2, through the incision made in the Mask 2.2; now slide the Mask Incision Plug 36 over the Mask Frame Prod 35.1, on the inside of the Mask 2.2 to seal and hold the Mask 2.2 in place against the Mask Frame 35 as shown in FIG. 12B-C.
[0082] Place each Mask Cord 2.2.1 securely around the respective Lower Cord Guide 32.4 and the Upper Cord Guide 31.1 as shown in FIG. 12B-C. Because the Mask Cords 2.2.1 reside on the Face Mask 30, the tension of Mask Cords 2.2.1 remains consistent throughout any movement of the Mask 2.2 so its positioning and shape is never compromised or accidently modified.
[0083] Rotate both Mask Knobs 33 forward until the Mask 2.2 is furthest from the Headband 10. Open the Face Shield 20 by rotating both Shield Knobs 21 backward to its outermost limit. Place the Headband 10 over the head and rest the Ear Adapters 11 on the ears. Adjust the Ear Adapters 11 horizontally in the Ear Chanels 10.3 if necessary. If the Headgear Assembly 1 is positioned to high, remove the Ear Adapters 11 and use the Headband 10 without them in which case, place the Inner Arm 10.2 on the respective ear.
[0084] After seating the Headgear Assembly 1 on the head. Close the Face Shield 20 by rotating both Shield Knobs 21 forward to the desired position. Next rotate both Mask Knobs 33 backward, direction D in FIG. 10C, until the Mask 2.2 is secured to the face.
[0085] To remove the Headgear Assembly 1, open the Face Shield 20 by rotating the Shield Knobs 21 backward completely as shown in FIG. 6D, and the Face Mask 30 by rotating the Mask Knobs 33 forward completely as shown in FIG. 10B, and then simply lift the Headgear Assembly 1 off the head.
