The present invention relates to a novel support device for a post that may take the form of a hollow or solid member.
Traffic markers or posts, referred to as delineators or channelizes, are commonly used on roadways to control traffic flow and to alert operators of vehicles to hazards. Traffic markers extend vertically from the surface of the pavements, specifically functioning to provide visibility or significant distances. Traffic markers are often contacted by vehicles and, thus, such markers require a high degree of flexibility and durability in order to remain in place.
In the past, many marker supports have been proposed. For example, U.S. Pat. No. 6,719,484 shows a novel marker support which is intended to resist vehicle impacts. In this regard, the US patent documents cited in U.S. Pat. No. 6,719,484 are incorporated by reference to the present application, as a whole, to denote the field of invention for the present application.
Unfortunately, vehicles tend to not only graze impact traffic markers, but often are the source of tire run-over and straddle hits. It is estimated that such contact with traffic markers may exert up to 73,000 lbs of force thereupon. Also, following the reception of such run-over and straddle hits, traffic markers must resume an original upright position to function, as heretofore described.
Thus, a support device for a marker which is extremely durable and flexible would be a notable advance in the vehicle traffic arts.
In accordance with the present invention a novel and useful support device for a marker is herein provided.
The support device of the present invention utilizes a base that includes a foot positioned at the ground surface. The foot maybe held to the ground surface by any suitable fastening means such as gluing, using fasteners such as screws, nails, spikes and the like. In addition, the foot may be weighted to simply lie atop the ground surface or be fixed below ground surface.
A hollow boss is also found in the present invention and extends outwardly from the base. The boss may include a cavity and an outer surface that lies apart from the cavity. Where the boss possesses a cavity, a first spacer is optionally positioned within the boss cavity. The spacer may take the form of a plug that may be composed of any suitable material such as wood, plastic, metal, and the like.
In certain cases, the boss and spacer may be formed as a single unit by molding, machining, or the like. The boss may also be adapted to extend various distances from the base depending on the dimensions of the traffic marker being held by the support device of the present invention. In certain cases, the base may be fashioned onto a single solid unitary member.
At least one fastener and preferably multiple fasteners are used to connect the first spacer to the boss possessing a cavity. The at least one fastener connecting one spacer to the boss includes a portion that extends outwardly from the outer surface of the boss. Where the base is a solid unitary member, a protuberance of various configurations may be used to create an outwardly extending portion.
A flexible sleeve lies over the outer surface of the boss and the fastener portion or protuberance that extends outwardly from the outer surface of the boss. The flexible sleeve may be formed of a very durable elastomeric material such as a spiral wound member. The portion of the at least one fastener extending from the outer surface of the boss may impinge upon the inner surface of the flexible sleeve and tend to deform the flexible sleeve outwardly from the boss to a certain degree.
A second spacer is positioned within the marker having a hollow shape being supported by the device of the present invention. At least a second fastener connects the second spacer to the hollow traffic marker. Again, the at least a second fastener possesses a portion that extends beyond the outer surface of the hollow traffic marker. The hollow traffic marker, the second spacer, and the at least second fastener lie within the flexible sleeve. The positioning of these elements are such that the first and second spacers position apart from each other and form a gap therebetween within the flexible sleeve. A first cinching band surrounds the flexible sleeve adjacent the at least a first fastener portioned extending outwardly from the outer surface of the boss. A second cinching band surrounds the flexible sleeve adjacent the at least a second fastener portion extending outwardly from the outer surface of the hollow traffic marker. The first and second bands are tightening to a degree to create indents to the outer surface of the flexible sleeve, such that the at least first and second fastener outwardly extending portions serve as stops for movement of the flexible sleeve away from the base.
In this regard, at least a third fastener may be employed to connect the second spacer to the hollow traffic marker such that a portion of the third fastener extends outwardly from the outer surface of the hollow traffic marker. The second band, cinched or tightened around the flexible sleeve, would then lie between the at least second and third fasteners to impede movement of the flexible sleeve toward or away from the base.
Where the marker and base are a solid member, a protuberance may be formed thereupon to create an indent to the flexible sleeve when cinched with a band, creating stops akin to the stops hereinabove described with respect to the hollow marker and the base having a boss with a cavity.
The device of the present invention may also include a base in which the spacer and boss include threaded surfaces that threadingly engage one another. In such a case, the first spacer and boss may be formed of a relatively rigid material such as metal, plastic, wood and the like. The cinching band may be located to engage a flange or a portion of the threaded surfaces.
In addition, the first spacer located in a hollow boss extending from the base may include a first plate and a second plate positioned apart from the first plate. The second plate lies against the foot of the base. A threaded bolt may exert a tensioning force to the first and second plates with the spacer lying between the first and second plates.
It may be apparent that a novel and useful support device for a marker has been hereinabove described.
It is therefore an object of the present invention to provide a support device for a marker that exhibits high durability from automotive impacts.
A further object of the present invention is to provide a support device for a marker that possesses great flexibility and is capable of resisting a tire run-over as well as a vehicle straddle hit and is capable of recovering to an original vertical position following such impacts.
Another object of the present invention is to provide a support device for a marker or post that is capable of accommodating various manufactured markers or post and is easily capable of effecting interchanging of traffic markers to comply with maintenance schedules.
Another object of the present invention is to provide a support device for a hollow or solid marker that may be placed upon a surface, fixed to a surface, or fixed below a surface for use.
Another object of the present invention is to provide a support for a marker that is durable, flexible and resistant to dislocation.
