Abstract:
A device used with a traffic cone to support caution tape includes at least one head extending from a body. The head is received in the opening defined at the top of a typical traffic cone to support the device in an upright position with respect to the cone. The body of the device is adapted to support a section of caution tape. The body may define a slot that allows the tape to be supported in an unfolded condition.
Abstract:
An anchoring base for a delineating pole using the reconfiguration of protruding resilient mechanical members to facilitate insertion and resist the subsequent extraction force on the pole. The mechanical members extend outwards relative to the insertion rod longitudinal axis, and bend or configure upon insertion of the anchoring base, into a first position that facilitates insertion while impeding and resisting axial extraction forces, and upon subsequent rotation of the anchoring base, the mechanical members bend or reconfigure into a second position such that the extraction resistance force is significantly reduced. The anchoring base design may be used in conjunction with a spring cartridge having a plurality of interlocking members forming a rigid mechanical structure during rotation.
Abstract:
A delineator mounting system has a coupler for mating a delineator having a cylindrical tubular lower end in a mount having square cross-sections.
Abstract:
A driver training device that facilitates practicing vehicle maneuverability tasks to help develop vehicle maneuverability skills. In one embodiment, the device includes a plurality of boundary markers interconnected by flexible connecting members. The flexible connecting members are movable from first positions wherein the boundary markers are in a compact arrangement, to second positions wherein the boundary markers are located in a predetermined arrangement and spacing that facilitates practicing a vehicle maneuverability task.
Abstract:
A ground anchor assembly for a guide post, the ground anchor assembly having a first part and a second part, the first part adapted to be pounded into the ground, the first part comprising a head portion and a tail portion, the tail portion being insertable into the ground, the head portion comprising a flat plate attached to one end of the tail portion, the flat plate comprising a pair of folded over tab members defining a slot, the second part comprising a first wall to which a road post can be attached and a second wall which comprises a tongue member and which can be inserted into the slot on the first part to attach the first part to the second part.
Abstract:
An impact recovery delineation quick connect/disconnect adapter system having plate studs and a pin that when added to the impact recovery delineation system allows the delineation panel, support post and load cell to be quickly connected to and/or disconnected from the supporting base (fixed or portable) with speed and without the use of any tools. The adapter plate which is connected to the load cell provides for radially aligned slots in a recessed platform to allow the plate to engage and lock with studs that are connected to the supporting base when the load cell is rotated about its vertical axis. The studs are particularly geometrically configured and have shoulder that is larger than the barrel and a head that is larger than the shoulder which results in a mechanical locking between the plate slots and the studs upon rotation of the plate with respect to the stationary studs. A quick release detent pin passes through aligned passages in the lower load cell element adapter plate and supporting base to prevent rotation of the load cell with respect to the horizontal axis of the base after connection is achieved. This provides a positive connection that is capable of withstanding multiple high speed impact by automobile vehicles without disengaging.
Abstract:
A traffic sign construction adapted to be selectively placed on top of a rigid base during certain periods, such as during school hours, periods when parking or turning is restricted, etc. The rigid base may be shaped like a conventional cast iron lane marker, having a convex top and a round bottom, and it is adapted to be permanently mounted along (or within) the boundaries of a vehicle roadway. A generally vertical bore in the center of the base extends to the top, so that a sturdy shank which has already been secured to the bottom of the traffic sign may be selectively inserted and removed from the bore without the requirement for any tools or special skill. A spring-loaded ball is preferably provided in either the bore or the shank, and a complementary recess is provided in the other of the two, so that they will be held together when they are subjected to only moderate loads-such as wind loads. When a person jerks the sign vertically upward, the spring-loaded ball will allow the sign to be separated from the base. Provision is made for washing out the interior of the base if it should happen to become fouled, by including openings at ground level which communicate with the vertical bore through appropriate passages. The ground-level openings (and passages leading thereto) are at least as large as the bore diameter, so that anything that can be put in the top of the base can be removed from the bottom. Also, no rain water is trapped in the base when the sign has been removed, because the ground-level openings preclude such trapping. No parts of the base are exposed to damage by vehicle wheels that might inadvertently pass over a base that has been permanently installed along a roadway. Preferably, the sign post is connected to the shank by an element which is relatively strong in tension but which will readily fail due to a significant shear load, such as when the sign is accidently struck by an errant automobile.
Abstract:
A stackable barrier unit includes: an elongate main body having a top surface, a bottom surface, longitudinal ends, and two sidewalls each having an upper margin joined to the top surface a lower margin extending tower than the bottom surface of the main body. A base width defined between lower outer margins of the sidewalls is greater than a top width of the top surface. Engagement extensions having engagement features extend from the longitudinal ends for linking two or more barrier units together. The engagement features may include a tapered pin and a hole. A rib may connect the first sidewall to the second sidewall below the bottom surface. A channel may be formed in the top surface of the main body directly above and parallel to the at least one rib.
