This application relates to the design and function of a base or mount for a delineator post. More particularly it relates to a base or mount which will accept a rapid, easy connecting and disconnecting highway traffic delineator post. Further, the base or mount is recessed in the road or support surface such that a snowplow or other highway clearing device may pass over it without damaging the delineator mounting components within the base.
U.S. Pat. No. 6,616,369, which is incorporated herein for all purposes, discloses a quick release delineator apparatus which fits into a permanent or portable base for the delineator system. It is an intention of the present invention to provide a base and mount for such a releasable delineator apparatus, which is recessable within the support surface for the delineator.
Current U.S. Pat. Nos. 5,277,513; 5,454,664; 5,816,737; 4,195,945; 4,147,447; and 3,587,416 disclose low-profile snowplowable pavement markers which incorporate a reflector lens element. These patents do not teach or disclose that a traffic delineator may be substituted for the reflector element. However, there has been a long standing need to be able to provide a suitable base (which will accommodate a traffic delineator post) which may be plowed over by a snowplow blade or other surface clearing device.
Often times during highway construction, delineators must be placed along the highway to direct traffic around the worksite. These delineators may be attached to a mount or base which is permanently affixed to the roadway or support surface. In some situations, the delineator may be disconnected from the base leaving the base exposed to the environmental conditions. When it snows, the delineators and bases become covered with snow. There is no convenient way to operate a snowplow around the delineator or base for removal of the fallen snow.
The present invention allows the delineator to be disconnected from the base, the plow to remove snow from the surface above the base, and the delineator to be quickly reintroduced into the base. Further, in those situations where the delineator had been detached from the base prior to the snowfall, the plow may simply run over the base or mount without damaging the base or mount. A delineator must be placed on the base after the snow removal.
A delineator post (11) with a section of signage (12) attached thereto is mounted to a support surface (14) by the base member (16) of the present invention. The support surface is generally the highway surface and the base member is permanently affixed to this surface. In the figures only a section of the support surface is illustrated. The highway surface (14) has a direction of traffic T indicated by the arrow. Normally the direction of traffic would be toward the signage (12), but occasionally a sign is misdirected. The delineator is designed to yield or collapse when impacted from either direction, but not when impacted in a cross traffic direction.
The lower knuckle (18) of the post (11) is easily and rapidly detachable from the base member (16) by releasing the detent latch (20) and rotating the knuckle (18) about the mounting studs (21). The complete operation of such a releasable knuckle is taught in U.S. Pat. No. 6,616,369, which is incorporated herein by reference for all purposes.
A snowplowable base member is a generally low profile structure with a ramping or sloping top surface to allow a plow blade to slide up and over the reflector lens housed in the base member. The base member is normally permanently affixed to the road surface and hold or retains the reflector lens. U.S. Pat. Nos. 5,277,513 and 5,454,664 teach the general construction and function of such a base member. However in the present invention the lens has been eliminated and central section of the base redesigned to accept a knuckle element of a delineator system.
As may be seen in
The knuckle (18) is placed over the central section with the stud head portions aligned with stud receiving openings in the knuckle. The knuckle is urged downwardly over the stud heads (22) and then rotated to allow the head portions (21) to slide over shoulders on the knuckle. This retains the knuckle to the base. The detent lock pin (20) is inserted through a hole in the knuckle and extends into the detent hole (28) in the bottom of the central circular notch (26) of the base body (17). The detent lock pin cooperates with the detent holes to restrict rotation of the knuckle in the base and keeps the head portions of the stud in contact with the shoulder of the knuckle. Thus, when the delineator post (11) is impacted, it merely deflects, collapses or folds about the flexing knuckle, but is retained in the base.
Although the invention has been described with reference to a specific embodiment, this description is not meant to be construed in a limiting sense. On the contrary, various modifications of the disclosed embodiments will become apparent to those skilled in the art upon reference to the description of the invention. It is therefore contemplated that the appended claims will cover such modifications, alternatives, and equivalents that fall within the true spirit and scope of the invention.
