Description

TECHNICAL FIELD

The present invention is categorized within the technical field of road traffic pylon safety and relates to an expandable and collapsible traffic warning device safety marker.

BACKGROUND OF THE INVENTION

The present invention relates to devices used to alert motorists to the existence of disabled vehicles or work zone areas. The volume of traffic incrementally increases each year resulting in a dangerous surrounding for occupants of disabled vehicles and personnel within a work zone. Many accidents that occur annually may have been prevented if oncoming motorists were alerted by a traffic warning device safety marker to the existence of disabled vehicles situated alongside the roadway. A variety of traffic warning device safety markers have become known over the years. Descriptions of such prior art of traffic warning devices are referenced in U.S. Pat. Nos. 3,618,556, 3,707,320, 4,197,607, 3,520,235, 4,006,702, 4,256,050, 5,305,705, 7,571,693, and 10,329,721.

An issue with respect to conveniently storing traffic warning devices in vehicles had prompted several attempts to provide an expandable and collapsible traffic warning device safety marker that can be condensed in size to reduce the required space for stowing in vehicles. Designs have ranged in many varieties, for example in U.S. Pat. Nos. 3,616,556 and 3,707,320, whereby the device's body is inflatable with air and attached to a base. Other designs have utilized coils or springs within its collapsible body, for example in U.S. Pat. No. 4,197,607 where a bolt mechanism to retain a condensed position and extending the conical body vertically once the spiral coil is released, and another variation in U.S. Pat. No. 3,520,235 which has a two-piece center module that requires assembly prior to use.

Other coil and spring variations are outlined in U.S. Pat. Nos. 4,006,702, 4,256,050, and 5,305,705. In other designs a folding mechanism is employed to collapse and expand the device's body such as outlined in U.S. Pat. Nos. 7,571,693 and 10,329,721.

Although prior art of traffic warning device safety markers provided designs for condensed traffic pylons, an inconvenience remains for the motorist to manually perform the task of expanding the traffic warning device's body which can be a frustrating and time-consuming endeavor when their attention is needed in solving the problem associated with their disabled vehicle alongside the roadway.

Furthermore, it has been a longstanding recognized problem as a safety concern in which many unnecessary fatalities and injuries resume annually related to incidents occurring with the presence of disabled vehicles alongside the roadway where traffic warning device safety markers may have aided in better visibility of motorists by oncoming traffic whereby a traffic warning device safety marker that is more convenient to store and deploy may further encourage its use by motorists during these hazardous situations.

SUMMARY OF THE INVENTION

Accordingly, the object of the present invention is to provide a traffic warning device safety marker that has a mechanically collapsible and expandable body member by employing a controllable linear motion machine assembly to perform the work within the traffic warning device safety marker, hence, achieving a condensed condition for the apparatus to occupy a minimum storage space when it is in a fully collapsed condition while eliminating the requirement inherent in other designs for exerting manual effort to expand and collapse the device's body member.

As such, the present invention offers an improvement over prior art as the traffic warning device safety marker's expandable and collapsible body member will conveniently expand and collapse mechanically by employing a controllable linear motion machine assembly upon the user's interaction with an actuator switch member whereby eliminating the requirement of the user to manually expand and collapse the device's body which may be more attractive to motorists and further encourage its use during hazardous situations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A preferred embodiment of the present invention will be described with reference to the associated drawings and several distinct elements are designated by the same reference numerals among all drawings when possible although different views may not show all components described hereinafter. The present invention will be described in several elements of which when integrated as described herein will enable one of ordinary skill in the art to made and use the present invention.

Referring to the drawings now wherein like reference numerals refer to like components throughout the various drawings reference numeral 4 is generally directed to the preferred conical shaped embodiment of the mechanically expandable and collapsible traffic safety warning device safety marker according to the present invention. In the preferred embodiment, it is evident the body is constructed in a shape of a cone as illustrated in FIGS. 1 and 3 herein; however, it may be structured in other shapes such as cylindrical round, rectangular, cylindrical square among other geometric configuration variations.

In the preferred embodiment and referring to the drawings, there is shown generally at 4 a mechanically expandable and collapsible traffic warning device safety marker comprising a conical shaped body member consisting of a plurality of truncated hollow vertical riser members 16 which telescope vertically by employing the use of a battery-powered telescopic linear actuator 26 of which retracts each vertical riser member 16 into a nested position when not in use as illustrated in FIG. 2 and expands each vertical riser member 16 upwardly into a fixed extended position perpendicular to the weighted base member 6 when in use as shown in FIGS. 1 and 3. The collapsible body member 12 is connected to the weighted base member 6 by a joining linkage member 14 that is attached to the lower vertical riser member 20 and the top side of the weighted base member 6 at their adjacent edges such that the joining linkage member 14 which is disposed in the interstice of the body member 12 and weighted base member 6 connects each component together.

Referring particularly to the preferred embodiment illustrated in drawings, the traffic warning device safety marker 4 assembly comprises a weighted base member 6, a collapsible body member 12, a telescopic linear actuator member 26, and a rechargeable battery 34. The height of the traffic warning device safety marker 4 can be any variation; however, in the preferred embodiment, it will preferably align with the height that satisfies the standards set forth by the Manual on Uniform Traffic Control Devices for high-speed roadways as the best mode for application. The dimensions of the weighted base member 6 will be proportionate to the height of the traffic warning device safety marker 4 such that it is designed to help the traffic warning device safety marker 4 to resist displacement under high wind forces. Presently, the preferred embodiment, for an example, has a total height of 28 inches from the bottom of the weighted base member 6 to the apex 24 of the collapsible body member 12 and a width of 14 inches for all four sides of the weighted base member 6; however, the height and width of the device can be any variation to satisfy the object of resisting displacement under high wind forces in other embodiments.

In the present invention of the preferred embodiment, the truncated hollow vertical riser members 16 are designed to fit inside of each other as to nest compactly within the inner compartment member 10 of the weighted base member 6 when retracted whereas the lower vertical riser member 20 is connected to the weighted base member 6 by a joining linkage member 14 that attaches the collapsible body member 12 to the weighted base member 6 whereby the series of vertical riser members 16 expand out of the nested flat position from inside the inner compartment member 10 of the weighted base member 6 to a fully vertically expanded position by the employment of a battery-powered telescopic linear actuator assembly 26 which is situated in the center of the inner compartment member 10 of the weighted base member 6. In the preferred embodiment, the vertical riser members 16 are described as forming a conical shape when expanded as shown in FIGS. 1 and 3 and retract to a flat collapsed condition as illustrated in FIG. 2.

In the preferred embodiment, the collapsible body member 12 is comprised of a plurality of truncated hollow vertical riser members 16 each having an equal length that are of conical shape but may be trapezoidal, rectangular, square, or other geometric configuration variations as referred and are designed of ever decreasing radius and circumference from the lower to the upper vertical riser members 16 so that the upper most vertical riser members nest within the adjacent lower vertical riser members when retracted downwardly to the extent that they collapse within the opening of the base member 6 and nest in the designated configured space of the inner compartment member 10 resulting in an effectively flat position when not in use for compaction to be stored more easily. The number of truncated hollow vertical riser members 16 employed depends on the configured size of the traffic warning device safety marker 4 to the extent that all vertical riser members 16 are having substantially equal length to properly fit inside of each other when nested within the inner compartment member 10 of the weighted base member 6. Contained between the lower vertical riser member 20 and upper vertical riser member 22 are a series of middle vertical riser members capable of extending upwardly into an expanded fixed position when the upper vertical riser member 22 is extended to the maximum height through the mechanical force exerted by the telescopic linear actuator 26.

In the preferred embodiment, the upper vertical riser member 22 is connected to the top of the upper telescopic linear actuator segment member 28 that allows for the lifting of the lower, middle, and upper vertical riser members when the designated directional actuator switch member 32 is initiated by the user and the retraction of the vertical riser members 16 when the user initiates the designated directional actuator switch member 32 to effectively condense the collapsible body member 12 for compaction when not in use. When the device is not in use, it will be understood that by pressing the directional actuator switch member to the intended function of condensing the collapsible body member 12, the series of vertical riser members 16 will retract downwardly into the inner compartment member 10 of the weighted base member 6 resulting in a condensed condition as illustrated in FIG. 2. It will be understood that by pressing the directional actuator switch member 32 to the intended function of expanding the collapsible body member 12, the vertical riser members 16 will expand upwardly out of the inner compartment member 10 of the weighted base member 6 resulting in an expanded condition ready for use as illustrated in FIGS. 1 and 3.

In the preferred embodiment, the truncated hollow vertical riser members 16 are constructed of a durable plastic material such as thermoplastic which is light weight, strong, heat resistant, easily moldable, recyclable, and preferably sourced from recycled products for environmental benefits but may be made of rubber, metal, or other materials having certain rigidity. The apex of the upper vertical riser member 24 is a sealed solid, flat, and waterproof surface contiguous with the top exterior surface of the upper vertical riser member 22 made of the same material as the vertical riser members 16 and is designed to prevent external elements and debris from accessing the internal construction of the traffic warning device safety marker 4.

In the preferred embodiment, the vertical riser members 16 are of vivid orange color commonly known as “dayglo” orange to be visible in the daytime but are not limited thereto. Conceptually, the collapsible body member 12 is preferably colored with luminescent, fluorescent, or reflecting material for better visibility. The vertical riser members 16 have been designed so that reflective decals or reflective collars can be affixed in various spacing to further enhance the visibility to motorists especially at night when the collapsible body member 12 is met by beams from a vehicle's headlights but may include various reflective paints during the molding process of the vertical riser members 16 to provide stripes or other patterns in accordance with traffic control design standards among other variations.

Referring to the drawings and in the preferred embodiment, elastic segment members 18 are situated in the interstice of each vertical riser member 16 and are adhesively attached to the vertical ends of the adjacent vertical riser members 16 such that they form a linkage between each vertical riser member 16. The elastic segment members 18 are made of an elastically deformable and waterproof material such as silicon that accommodatively flexes when the vertical riser members 16 retract and expand to provide a strong adhesive linkage between each adjacent vertical riser member 16 and a watertight seal. The material used to construct the elastic segment members 18 can be selected from but are not limited to an elastically deformable silicon or other plastic materials as these materials have better flexibility, plasticity, and strength; however, may be made of other materials that provide a durable flexibility and a watertight seal in other embodiments.

In the preferred embodiment and referring to the drawings, the lower elastic segment member 40 is secured to the lower vertical riser member's 20 bottom end and attached to the upper end of the joining linkage member 14. The linkage member 14 is attached to the top exterior surface of the weighted base member 6 providing the joining of the collapsible body member 12 and the weighted base member 6. In the preferred embodiment, the joining linkage member 14 is constructed of a rubber material to provide flexibility and durability during the retraction of the vertical riser members 16 into the weighted base member 6 but is not limited to and may be made of elastically deformable silicon or other durable and flexible materials in other embodiments.
