No. D412,131 describes a traffic channelizing system design. Alt, U.S. Pat. No. D419,901 describes a safety marking pylon design. Abrams, U.S. Pat. No. 3,380,428 describes a traffic guide post means comprising a post member and a base member of mutually interfitting relationship. Lyons et al., U.S. Pat. No. 3,933,118 describes a signal device combining a fluorescent or phosphorescent light tube and a weighted base designed to be thrown or dropped from a vehicle as a warning marker. The light tube is preferably of the chemically actuated type and the base preferably has four resilient legs serving to ensure that the device will assume an upright position when dropped. Beard, U.S. Pat. No. 4,925,334 describes a traffic marker including an upright cone-shaped member and a base. Two orifices are provided on the upper end of the cone-shaped member and on opposite sides thereof A bracket is provided having an interior portion and an exterior portion. The bracket is operable to be inserted through the orifice such that the distal end of the interior portion contacts the interior surface of the cone-shaped member at a point. An orifice is disposed in the interior member through which a flag can be inserted. The flag is inserted through the orifice on the opposite side of the cone-shaped member through the orifice to contact the opposite sides of the interior surface of the cone at a point. Thurston, U.S. Pat. No. 5,036,791 describes a stackable road delineator including an upright conical portion with a detachable weighted base. The top conical end has a handle graspable by the fingers of a human hand. Also, this end has a conical hollow interior so that when it is stacked on top of another similar delineator, the handle will freely fit within this hollow interior to thus provide stackable delineators. Kulp et al., U.S. Pat. No. 5,749,673 describes a safety delineator which includes a conical body portion to which is attached one or more vertical panels. A new and improved handle feature permits easy and comfortable full hand gripping of the delineator and also prevents sticking and jamming together of a plurality of the delineators when they are stacked. The delineators may be stacked without removing the vertical panels, since each vertical panel is particularly designed to wrap around the conical body portion to which it is attached as another vertical delineator slides over it. Ahn, U.S. Pat. No. 5,908,262 describes a basally adhered, self-recovering traffic lane delineator having a cylindrical post made of flexible material, having the air outlet and inlet on the center of its upper surface, and a supplementary support panel placed and adhered underneath the post. The support panel supports a lower part of the post and is adhered on the ground. Owing to its small package volume, the delineator is easy to move and safeguard. Bent et al., U.S. Pat. No. 6,014,941 describes a traffic delineator including a cylinder and a base. The base has a hole therethrough to permit the cylinder to be inserted into the base and the base then holds the cylinder down. A grip is formed in the center section of the cylinder to increase ease of carrying the delineator. The cylinder may also include a handle and means for affixing traffic warning lights and flags. The base may include means for holding removable ballast. The cylinder is formed by blow molding. Eberle et al., U.S. Pat. No. 6,131,320 describes a free standing display panel with a foldable floor sign including an integrally formed handle portion and male and female hinge projections. The male and female hinge projections snap together into interlocking engagement with each other in response to simultaneous axial compression. The male coupling member includes a resilient finger portion and a latching head, and the female coupling member includes a cylindrical collar having a latch pocket and a radially stepped, inwardly projecting retainer. The resilient finger portion is radially deflectable in response to sliding engagement of the latching head against the retainer to permit the latching head to clear the retainer and enter the latch pocket. The display panels are stabilized in a spread-apart service position by a locking arm that is pivotally coupled to the display panels for folding movement within longitudinal slots formed along side edges of the display panels. Two or more floor signs are linked together by chains to provide a wide area barrier to entry.
Our prior art search, described above, teaches road delineators with conical and wedge shaped bodies, disc shaped bottom plates and flat panels mounted upright on the bodies, stackable construction, and of molded plastic materials. However, the prior art fails to teach a base with insertable upright for holding a sign, wherein the base is made of a highly resilient material and has an insert of a highly rigid structural material for securing the inserted upright. The present disclosure distinguishes over the prior art providing heretofore unknown advantages as described in the following summary.
BRIEF SUMMARY OF THE INVENTIONThis disclosure teaches certain benefits in construction and use which give rise to the objectives described below.
A road sign base is constructed of a high density, resilient, shock absorbing material such as rubber. It provides a top surface, a bottom surface and one or more strut apertures between them. A receiver plate of a rigid structural material such as structural grade polymer plastic is engaged with the base in proximity to the bottom surface. One or more vertical struts are received within apertures through the top surface for supporting a sign. The base provides adequate weight to support the sign in high winds while providing energy absorption should contact with moving vehicles occur. The receiver plate provides rigid surfaces for mechanical coupling with the struts. Struts of various shapes and sizes are able to be engaged with the apertures using adaptors so that the system is able to be adapted for various uses. A plurality of the bases may be stacked, one on top of the next, each nestling within the other, so that they may be transported without taking up excessive storage space.
A primary objective inherent in the above described apparatus and method of use is to provide advantages not taught by the prior art.
Another objective is to provide a road sign base structure that is highly resilient upon impact yet has a relatively high weight density for temporary sign anchoring.
A further objective is to provide such a sign base that may be adapted to receive a wide range of sign posts or struts having different sizes and shapes.
A still further objective is to provide such a sign structure and system that is highly portable and compact in storage due to nesting features.
A primary objective inherent in the above described apparatus and method of use is to provide advantages not taught by the prior art.
Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the presently described apparatus and method of its use.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING(S)Illustrated in the accompanying drawing(s) is at least one of the best mode embodiments of the present invention In such drawing(s):
The above described drawing figures illustrate the described apparatus and its method of use in at least one of its preferred, best mode embodiment, which is further defined in detail in the following description. Those having ordinary skill in the art may be able to make alterations and modifications what is described herein without departing from its spirit and scope. Therefore, it must be understood that what is illustrated is set forth only for the purposes of example and that it should not be taken as a limitation in the scope of the present apparatus and method of use.
The presently described apparatus is a traffic ballast system for supporting signs, reflective surfaces and symbols for directing and informing motor traffic. The apparatus is constructed of a base 10 whose material makeup is preferably one of natural or synthetic rubber but also can be constructed of any rubber-like material such as a rubberized plastic. Generally, this material is not rigid and therefore enables a supported sign to yield to contact with a moving vehicle. The primary objective here is to enable the base 10 to provide ballast in supporting temporarily placed signs effectively in windy conditions. The base 10 provides a top surface 12, a bottom surface 14 and a strut aperture 20, whereby the word “aperture” as used herein may take the singular or plural meaning. The aperture 20 extends into the base through the top surface 12 and may or may not extend through the bottom surface as shown in
A receiver plate 50 is made of a rigid structural material such as metal or hard plastic. Plate 50, shown in

The tubular adaptor 40 is preferably comprised of plural strips 42 which are arranged in side-by-side juxtaposition and separated by margins 44; the margins 44 having a wall thickness less than the strips 42 so as to permit folding as shown in
The base 10 provides at least one elongate hole 16 between the top 12 and bottom 14 surfaces and adjacent to a peripheral edge 11 as shown in
As shown in
The enablements described in detail above are considered novel over the prior art of record and are considered critical to the operation of at least one aspect of the apparatus and its method of use and to the achievement of the above described objectives. The words used in this specification to describe the instant embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification: structure, material or acts beyond the scope of the commonly defined meanings. Thus if an element can be understood in the context of this specification as including more than one meaning, then its use must be understood as being generic to all possible meanings supported by the specification and by the word or words describing the element.
The definitions of the words or drawing elements described herein are meant to include not only the combination of elements which are literally set forth, but all equivalent structure, material or acts for performing substantially the same function in substantially the same way to obtain substantially the same result. In this sense it is therefore contemplated that an equivalent substitution of two or more elements may be made for any one of the elements described and its various embodiments or that a single element may be substituted for two or more elements in a claim.
Changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalents within the scope intended and its various embodiments. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. This disclosure is thus meant to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be lo obviously substituted, and also what incorporates the essential ideas.
The scope of this description is to be interpreted only in conjunction with the appended claims and it is made clear, here, that each named inventor believes that the claimed subject matter is what is intended to be patented.
