The present invention relates to the field of helmets that can be used for any number of purposes and, more specifically, to helmets that can be used with a visor that is moveable between a stored position and a deployed position.
In general, helmets themselves are well known in the art and have been a part of personal protection equipment for the vast majority, if not all, of recorded history to provide protection to the head in a variety of situations. Helmets have been used extensively by workers, hobbyists, law enforcement, soldiers, pilots, and many others for numerous applications with the primary function of these helmets to safeguard the wearer from potential hazards or injury.
In the realm of aviation, law enforcement, or the military, helmets often incorporate additional features and tools such as optics, flashlights, storage, visors. Visors often serve to cover or shield the wearer's eyes from a number of environmental conditions, including glare or flying debris or can incorporate certain technologies to provide a wearer with a number of different viewing capabilities or displayed information. However, the prior art have failed to provide certain functionalities of helmets, and of visor helmets that create a need for improvement. For instance, and without limitation, a few failures of the prior art include the helmets being limited to visors only being deployable via sliding movements with the helmet, the visors do not allow for non-helmet-integrated headsets or headphones to be worn with a visored helmet.
In the prior art, the adjustment of the visor height is often achieved through the use of hand-screws, such as clicking hand-screws. This requires fine motor skills and is often time-consuming, especially in situations that call for fast action. Also, the hand-screws can be difficult to operate with gloves on or in cold weather conditions. Moreover, the clicking mechanisms of hand-screws quickly wear out over time due to normal wear and tear, leading to less precise adjustments or total failure of the visor. Additionally, the hand-screws are often uncomfortable to use and can even be painful to use after prolonged operation of the hand-screws.
Sliding visors of the prior art frequently malfunction due to debris being present on the visor, and also are often unable to be quickly deployed since they require a pull force on the sliding visor which is in a specific correct direction directed away from the helmet. Sliding visors often also include a high coefficient of friction in order to hold the sliding visor at a selected position of a wearer, which often prevents fast deployment of the sliding visor from the helmet, which is largely an issue and undesirable, especially in time sensitive scenarios.
One example of a prior art helmet is offered by Gentex® under model number HGU-56/P. This helmet does not allow for the visor to be carried inside the helmet body, i.e., the visor is positioned exterior to the protective helmet shell under a non-structural cover when in the stored position to keep it from getting scratched when not in use. This extra visor cover adds weight, bulk, and cost to this helmet. Further, the Gentex® HGU-56/P helmet does not allow for use in connection with a separate independent headset and can only use headphones built into the helmet. As is the case with most prior art helmets that attempt to incorporate retractable visors, a significant issue arises with the path of travel of the visors with respect to their use in conjunction with headsets. As such, the prior art solutions are either forced to position the visors external to the helmet shell, and/or use sliding track mechanisms (as opposed to pivot mechanisms) to store and deploy the visors.
Therefore, there is a need for a system and/or method that solves at least one of the above issues left by the prior art.
This background information is provided to reveal information believed by the applicant to be of possible relevance to the present invention. No admission is necessarily intended, nor should be construed, that any of the preceding information constitutes prior art against the present invention.
With the above in mind, embodiments of the present invention are related to a helmet visor system that includes a helmet shaped to accommodate a headset. The helmet may also include a helmet interior and a helmet exterior. The system may further include a visor lens that may be retractably carried by the helmet, and a visor apparatus carried by the helmet. The visor apparatus may be connected to the visor lens to pivotally move the visor lens between a stored position and a deployed position. The deployed position of the visor lens may be defined as a majority of the visor lens being extended from the helmet. The stored position of the visor lens may be defined as the majority of the visor lens being occluded by the helmet. The visor lens may be pivotally moveable between the stored position and the deployed position so as not to interfere with the headset. The visor lens being occluded by the helmet may be defined as the visor lens being positioned within the helmet interior.
The system may also include a first visor carrier and a second visor carrier. Each of the first visor carrier and the second visor carrier may have portions connected to the visor lens and portions pivotally connected to the helmet.
The system may further include an actuation knob that extends through a visor actuator slot and is attached to the first visor carrier. The actuation knob may be movable between an upper portion of the visor actuator slot and a lower portion of the visor actuator slot. The actuation knob may be moveable between an engaged position and a disengaged position when positioned in one or both of the upper portion and lower portion of visor actuator slot. When in the disengaged position, the actuation knob may be moveable between the upper portion and the lower portion of the visor actuator slot. When in the engaged position, the actuation knob may be fixed from movement between the upper portion and the lower portion of the visor actuator slot.
The actuation knob may be movable between a stored locked position and a deployed locked position. The stored locked position may be defined as when the actuation knob is moved to the upper portion of the visor actuator slot and in the engaged position. The deployed lock position may be defined as when the actuation knob is moved to the lower position of the visor actuator slot and in the engaged position.
The system may also include a knob lock spring to cause the actuation knob to move from the disengaged position to the engaged position. The system may further include a positioning hook rotatably attached to the helmet and moveable within the visor actuator slot.
An end portion of the positioning hook may define the lower portion of the visor actuator slot. The positioning hook may be moveable to a user selected position within the visor actuator slot to define the lower portion of the visor actuator slot.
The system may also include a pivot member that may be adapted to engage a pivot through hole formed in a side portion of the helmet. The pivot member may be connected to a portion of the positioning hook. The positioning hook may be rotatably moveable with respect to the pivot member.
The system may further include a lock screw that is adapted to engage the positioning hook and is moveable within a lock screw slot. The lock screw may be moveable between a fixed position and an unfixed position. The unfixed position of the lock screw may allow the positioning hook to be rotatably moved within the visor actuator slot. The fixed position may lock the position of the positioning hook within the visor actuator slot.
The first and the second visor carriers may each include a first lever and a second lever to removably connect the first and second visor carriers to the visor lens. Both the first and second levers may be movable between a locked state and an unlocked state.

The second lever 122 may be configured to engage with the engagement point 144 on the visor lens 110. The second lever 122 may be readily movable from a locked state to a released state. The locked state of the second lever 122 may be defined as when the second lever 122 is in contact with and engaging an engagement point 144 on the visor lens 110. The unlocked state of the second lever 122 may be defined as when a force is applied to the second lever 122 so that the second lever 122 is not engaged with an engagement point 142 on the visor lens 110.
Now referring to
Some embodiments of the present invention may include a visor actuator slot 126, an actuation knob 128, a positioning hook 132, a positioning lock screw 134, and a lock screw slot 136. The visor actuator slot 126 may be located on and extending through a portion of the helmet 102. The actuation knob 128 may be attached to extending from one of the lens carriers 118 and the actuation knob 128 may be positioned extending through the visor actuator slot 126. The actuation knob 128 may actuate relative to the respective lens carrier 118 that the actuation knob 128 is attached to, and the actuation knob 128 may include a knob lock spring 130 attached to and extending between the actuation knob 128 and the lens carrier 118. The actuation knob 128 may have varying widths such that when the actuation knob 128 is pulled upon directed away from the lens carrier 118 that the actuation knob 128 is attached to, that the actuation knob 128 reveals a portion thereof that is smaller than the width of the visor actuator slot 126.
The knob lock spring 130 may be configured to apply a constant force on the actuation knob 128 towards the respective lens carrier 118. The visor actuator slot 126 may include an upper portion 138 (the upper position slot) and a lower portion 140 (the lower position slot). The upper position slot 138 of the visor actuator slot 126 may comprise of a width equal to or greater than a width of the actuation knob 128. The lower position slot 140 of the visor actuator slot 126 may have a width that is greater than the width of the actuation knob 128.
The positioning hook 132 may be rotatably connected to the pivot member 112, and the positioning hook 132 may extend adjacent to the lower position slot 140 of the visor actuator slot 126. The positioning hook 132 may have its adjacent position relative to the lower portion of the lower position slot 140 of the visor actuator slot 126 adjusted by the positioning lock screw 134. The positioning lock screw 134 may extend into a lock screw slot 136 that extends through at least one of the helmet exterior 106, the positioning hook 132, the helmet interior 104, and one of the lens carriers 118. The lock screw slot 136 may have a width that is equal to or greater than a portion of the positioning lock screw 134, and the lock screw slot 136 may have an elongated shape along the helmet 102, for example, and without limitation, a uniform elongated oval shape.
The positioning lock screw 134 may be readily fixed and unfixed to adjust the placement of the positioning hook 132 adjacent to the lower position slot 140 of the visor actuator slot 126. The position of the positioning hook 132 may limit an extent to which the visor lens 110 can move to a deployed position from a stored position. This is advantageous as the face configuration of users may differ and it may be necessary for users to require the visor to be deployed to different positions. Accordingly, the interaction of the positioning lock screw 134 and the positioning hook 132 may advantageously allow for customized deployment of the visor lens 110. The deployed position of the visor lens 110 may be defined as when a majority of the visor lens 110 is visible and extending from the helmet 102 when the visor lens 110 and the lens carrier 118 are rotatably moved relative to the helmet 102. The stored position of the visor lens 110 may be defined as when a majority of the visor lens 110 is not visible and occluded by the helmet.
Upon the visor lens 110 being moved to the deployed position, the positioning hook 132 may engage, catch, and/or abut the actuation knob 128 such that the visor lens 110 is prevented from further extending from the helmet 102. Upon the visor lens 110 being moved to the deployed position, the actuation knob 128 may be matingly engaged with the positioning hook 132 by being pulled towards the lens carrier 118 that the actuation knob 128 is attached to by the knob lock spring 130, which may be defined as when the actuation knob 128 is in a locked deployed position. The actuation knob 128 may be moveable to a stored locked position. The stored locked position may be defined as when the visor lens 110 is in the stored position and the upper position slot 138 of the visor actuator slot 126 is positioned between the actuation knob 128 and the lens carrier 118 that the actuation knob 128 is attach to, and the knob lock spring 130 forces the actuation knob 128 to engage with the upper position slot 138 of the visor actuator slot 126, preventing the visor lens 110 from rotatably moving relative to the helmet 102.
The visor lens 110 may be removeable from the lens carriers 118 that it is attached thereto. To remove the visor lens 110 the first levers 120 may first be moved to the unlocked state to disengage their respective engagement points 144 on the visor lens 110, as illustratively shown in
The helmet 102 may include two cutouts 116 to allow for a user of the helmet to wear a headset 124 simultaneously with the helmet 102, as illustratively shown throughout the figures. The cutouts 116 may be extending through and located adjacent to a lower side-central portion of the helmet 102, essentially where a user's ears are expected to be positioned when wearing the helmet 102. Due to the placement of the cutouts 116 to accommodate a headset 124 worn by a user, those skilled in the art will notice and appreciate that the pivot member 112 of the visor apparatus 108 is placed in a position on the helmet so that the configuration of the pivoting of the visor allows for the visor lens to be moved without any interference or without moving the visor into the area of the helmet that has cutouts for the ears. This advantageously allows for a headset to be worn by the user without any interference from the visor lens being moved between the deployed position and the retracted or stored position.
Some of the illustrative aspects of the present invention may be advantageous in solving the problems herein described and other problems not discussed which are discoverable by a skilled artisan.
