Warning device for roadside stops

Abstract

A warning device or apparatus for use during roadside stops, with means to display one or more warning messages on the front of the warning device or apparatus at a height to be easily and quickly seen by oncoming drivers. The warning device may be a warning triangle, although other shapes may be used as appropriate according to the customs or laws for particular regions or areas. One or more message plates can be mounted on the warning device, with various messages selected according to the circumstances. An electronic message board may be similarly mounted.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

(6) In various exemplary embodiments, the present invention comprises a warning device or apparatus for use during roadside stops, with means to display one or more warning messages on the front of the warning device or apparatus at a height to be easily and quickly seen by oncoming drivers. The present invention thus draws the attention of oncoming drivers to the presence of the stopped vehicle and the dangerous circumstances, thereby increasing safety and reducing fatalities.

(7) In the embodiment shown in FIGS. 1-2, the warning device comprises a warning triangle 10, although other shapes may be used as appropriate according to the customs or laws for particular regions or areas. The warning triangle may be made of any suitable material, including, but not limited to, plastic, wood, metal, or combinations thereof, and should be an appropriate color (e.g., orange) and reflective, in accordance with customs or laws for particular regions or areas. In some exemplary embodiments, the warning device may comprise a cone, barrel, stand, rack, or other object that be readily moved and positioned as needed.

(8) The warning triangle can be held in an upright position by a variety of means, such as a support rod or beam extending from the back, or a base to which the warning triangle is attached. As seen in FIG. 1, in one embodiment the base 20 comprises a cross with two arms intersecting at an angle (in the embodiment shown, at a substantially 90-degree angle). The bottom of the warning triangle comprises two tabs 12 that fit into corresponding slots 22 in the base. This arrangement holds the warning triangle in a secure upright position without use of a support rod or beam, with the arm extending to the front and back of the triangle preventing the triangle from tipping in either direction. This avoids the problem of the triangle being blown or falling forward (which a support rod can do nothing to prevent), or having the support rod being blown or knocked away.

(9) Support means are provided on the front or back of the warning triangle itself at a height above the base. Support means receives and provides secure support for a message plate (which may be selected from among a plurality or set of such plates) 30. Raising the message plate near or above the top of the triangle, or in the upper half of the triangle, makes it more visible to an oncoming driver, and its height and position on the triangle draws the oncoming driver's attention immediately to the message as part of the warning. It also allows the driver's focus to stay at a higher level and not be drawn downward, thereby further enhancing safety.

(10) As seen in FIGS. 1 and 2, in one embodiment support means comprises a pair of clips or holders 24 fastened to the triangle at their lower ends 26, one on each side of the triangle. The top end 28 is open, and the message plate slides down into the clips or holders. The top end of the clips can be biased against the triangle, so as to hold the message plate more securely in place through friction. The clips may be angled so as to parallel the triangle element to which each is attached, or may be positioned at some other angle (e.g., straight vertically with respect to the bottom of the triangle). In one embodiment, the clips or holders are removably attached or fastened to the triangle (e.g., through snaps, rods, or tab inserts into a corresponding slot in the triangle), so that the clips or holders can be removed, thereby allowing use of the triangle alone. In another embodiment, the clips or holders are permanently fastened. The clips or holders may be made of any suitable material, including, but not limited to, plastic, metal, wood, or wire, and be solid, translucent, transparent, or open (e.g., wire frame). The clips or holders may extend for the width (or more) of the message plate, or only part of the width of the message plate.

(11) In yet another embodiment, additional sets of clips or holders may be positioned above or below the first set, thereby allowing two or more message plates to be used simultaneously.

(12) In yet a further embodiment, the top end of the clips also are fastened to the triangle. Message plates would then be inserted sideways through the clip or holder. Other means of attachment also may be used, such as hooks (inserted through holes in the plates, the triangle, or both), springs, hook-and-loop fasteners 36 on the face of the triangle and the back of the message plate (as seen in FIGS. 4A and 4B), or the like.

(13) Examples of messages on the message plates 30 are seen in FIG. 3. Messages can be in any language and in any font, of any length (although short, concise messages are better). Messages also can be non-text, such as symbols or pictures or color. Messages can appear on one side of the message plate, or both. The message plates can be made of any suitable material, including plastic, metal, wood, or combinations thereof.

(14) In one embodiment, the message text is black against a white or very light background, for greatest contrast. In another embodiment, the text itself is brightly colored or reflective, to promote visibility, especially at night. In yet another embodiment, the message text may be lit (such as through LEDs or the like).

(15) In yet a further embodiment, the message plate comprises a programmable electronic message plate or board 40, as seen in FIG. 5, where the user can select one or more pre-programmed messages to be shown on the message board display. The user also may be able to customize messages, or type in a message suitable for the situation. In this embodiment, the message board comprises a separate power source (such as batteries), an on/off switch, a display screen 42 on the front of the message board, and a programmable user interface with a central processing unit for interacting with and controlling the message board. In yet a further embodiment, the message board has wireless communications capacity, allowing a user to program or control the message board through a smart phone, tablet computer, or other computing device.

(16) While the above invention has been described in the context of roadside use for a stopped or broken down vehicle, it can also be used in other situations to provide a warning. For example, it may be used to indicate the presence of workers or workcrews, such as construction or roadway workers, or a tree-cutting truck and crew, with appropriate messages (e.g., MEN AT WORK, TREE CUTTING). It also may be used to indicate hazards (e.g., FLOODING, TREE DOWN, LINE DOWN). Further, it may be used in non-traffic situations, such as to indicate the presence of hazards in another outdoor or indoor space (e.g., WET FLOOR).

(17) In a further embodiment, the message plates may be used separately from the warning triangle or cone, particularly in situations where the warning triangle or cone cannot be safely or securely positioned.

(18) Thus, it should be understood that the embodiments and examples described herein have been chosen and described in order to best illustrate the principles of the invention and its practical applications to thereby enable one of ordinary skill in the art to best utilize the invention in various embodiments and with various modifications as are suited for particular uses contemplated. Even though specific embodiments of this invention have been described, they are not to be taken as exhaustive. There are several variations that will be apparent to those skilled in the art.
