## Background
CROSS REFERENCE TO RELATED APPLICATIONS
The present application is a non-provisional application that claims priority and incorporates by reference in its entirety provisional U.S. patent application Ser. No. 61/115,538, entitled “Rear View Safety Device” filed on Nov. 17, 2008.


TECHNICAL FIELD
Embodiments of the present disclosure generally relate to various forms of vision enhancement safety devices. More particularly, the embodiments of the present disclosure relate to safety systems and devices to improve peripheral vision.
BACKGROUND
Reflective safety devices have been used to provide a rear view for driving, cycling, and other activities where turning the head to obtain a view is either unsafe or difficult due to circumstances. Often the individual needing the enhanced vision moves comparatively little, but is surrounded by a working environment with a number of dangerous moving objects or the individual simply needs to have a better perspective of their surroundings. Examples of these individuals include motorcyclists, safety flaggers, factory or plant employees, traffic police, construction site workers, firefighters, forklift and other equipment operators, hunters, joggers, cyclists and other athletes.
Existing reflective devices may only provide limited vision enhancement, while introducing cumbersome extensions that may actually present addition safety hazards to the individual. These extensions are often attached to a clothing article, such as a hat or other form of headgear and often prevent use of the clothing article for other activities. Additionally, some existing reflective devices actually extend into the path of traffic may be clipped or knocked by a passing vehicle and thereby knock anything attached to the device, which at best might knock off the hat or glasses, but at worst could potentially twist the head of the wearer. The potential risk of injury is often exacerbated when the respective reflective device is irremovably attached.
SUMMARY
It is accordingly an object of the disclosure to provide a peripheral vision safety device that overcomes the hereinafore-mentioned disadvantages of the heretofore-known mechanisms of the general type currently employed in the safety gear industry. The described apparatus, methods and systems of reflective safety gear expand the zone of vision for individuals. More specifically, embodiments of the disclosure are configured to expand and clarify peripheral vision and reduce the individual's risk of injury or death from passing vehicles, heavy equipment and other hazards not in their direct line of sight.
More particularly, a peripheral vision device having a clamp configured to couple the device to a safety helmet and an adjustable reflective device repositionable to extend the peripheral vision of the individual wearing the safety helmet. An adjustable arm of the peripheral vision device being coupled between the clamp and the reflective device to place the reflective device into a visible location below the brim of the safety helmet. In accordance with an additional mode of the disclosure, the coupling between the arm and the clamp utilizes a hinge having dual circular connectors, each connector having at least one side exhibiting radial triangular corrugation. In accordance with yet another mode of the disclosure, the clamp includes lever to fixable position and/or secure the peripheral vision device on the safety helmet. In accordance with a further mode of the disclosure, the peripheral vision safety device includes a bead receiver on the clamp to secure the position of the peripheral vision safety device on the safety helmet.
With the foregoing and other objects in view, there is provided, in accordance with the disclosure, a safety threshold breakaway method that initially holds the peripheral vision safety device to a safety helmet, but upon impact or inappropriate application of torque allows portions of the device to breakaway or separate in an effort to alleviate the relative force of the impact of the contact to the wearer of the safety helmet.
In accordance with a further mode of the disclosure, the peripheral vision safety system allows the devices to be stored in the safety helmet to help ensure their use.
Other features that are considered as characteristic for the disclosure are set forth in the appended claims.
Although the disclosure is illustrated and described herein as embodied in apparatus, methods, and systems for expanding peripheral vision, it is, nevertheless, not intended to be limited to the details shown because various modifications and structural changes may be made therein without departing from the spirit of the disclosure and are within the scope and range of equivalents of the claims.
The construction and method of operation of various embodiments in the disclosure, however, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings and claims.

Referring now to FIG. 1, a perspective view in elevation showing a rear view safety device 100 is shown in accordance with various embodiments of the present disclosure. Rear view safety device 100 supplements peripheral vision without hindering direct forward vision. The illustrated embodiment of the rear view safety device 100 includes a clip 110 to attach to a bill or brim of a headcovering, an arm 120 for adjusting height, and an adjustable mounting bracket 130 for securely holding a reflective surface 140.
In the illustrated embodiment, the mirror and/or reflective surface 140 includes a generally planar protective surface, which may either directly exhibit reflective properties or be combined with at least one underlying reflective layer. For example, in one embodiment the reflective surface 140 includes a substantially transparent substrate layer of material and a second reflective substrate layer including at least partially reflective material. In one embodiment, the reflective surface 140 when properly positioned and adjusted is configured to provide a field of view extending to the horizon from a line perpendicular to a longitudinal plane tangent to the individual's side, the field of view also extending out from the tangent plane and behind the eyes of the individual. Accordingly, depending on relative eye position of the individual to the rear view safety device 100, an additional segment of peripheral vision may be available to the individual. In one embodiment, the additional segment may include up to about 180° of peripheral vision. The reflective surface 140 may also be configured to enhance or enlarge images from behind.
In one embodiment, a compound mirror may be used to enlarge the field of view and eliminate potential blind zones near the individual wearing the rear view safety device 100. The compound mirror may include a secondary spherically convex reflective surface to view zones not directly visible in the primary reflective surface of the compound mirror.
The clip 110 includes a lever 150, notch 160, slot 170, and hinge joint 180. The lever 150 having at least an unlocked position and a locked position.

The slot 170 is configured to detachably secure to an edge of a headcovering. In one embodiment the clip 110 is able to attach to the edge of a headcovering through tension created by separating top and bottom portions of the clip 110. In addition, the clip 110 may be locked into place on the edge of the headcovering via the lever 150. In one embodiment, the lever 150 is substantially parallel to the slot 170 in the locked position and substantially perpendicular to the slot 170 in the unlocked position. In the locked position, the lever 150 butts against the bead of the headcovering in the notch 160. In the unlocked position, the clip may slide along the edge of the headcovering following the track provided by the bead of the headcovering. On hats without a bead on the edge, safari style hats, or other thin hats spacer pads may be added to the brim/bill of the hat so that the rear view safety device 100 may be attached. Once the spacer pads are properly positioned, the slot 170 of the unlocked clip 110 may slide into position before the lever 150 is moved into the locked position.
Hinge joint 180 forms an adjustable connection between the clip 110 and the arm 120. The hinge joint 180 includes at least one connector from the clip 110 and at least one connector from the arm 120 that, when connected, selectively secure a relative position of the clip 110 with respect to the arm 120.
