  • Patent number: 5671563
    Abstract: A vehicle control gate arrangement pivotable to a position for restricting flow of vehicular traffic where the gate is generally elongate and can include a tubular shell and a core member where the shell is more flexible than the core and contacts the core substantially continuously around the periphery of the core. The core can be terminated toward the distal end of the gate so that the shell extends outwardly from the termination of the core so that vehicles attempting to bypass the end of the gate but failing to do so, strike the flexible end of the gate so the gate is not damaged or knocked down. An arrangement is also provided to include a gate composed of one or more sections connected to an adjacent section or to a pivot by a joint assembly which releases the outermost section in the event the section is struck by a vehicle attempting to or accidently going through the gate.

  • Patent number: 5634733
    Abstract: The coupler has, in several embodiments, a compliant-link having flexible or pivoted fingers that engage a groove in the inside of a lower link in at least three places. The groove appears much like a bearing race. The compliant-link is retained inside of an upper sleeve that is attached to an upward-extending post. The lower (engaging) link is attached to a downward-extending post. The fingers are able to disengage from the groove under spring action and thus a sufficient applied moment will cause disengagement. Disengagement does not cause anything to break. Assembly, or reassembly, of the coupler may be performed without extra parts or tools. In several of the embodiments, the decoupling moment may be manually adjusted using less moment than the resultant decoupling moment. The decoupling moment is essentially independent of azimuth. The coupler is particularly suited to being used with rural type mailboxes, and warehouse buffers and supports.

  • Patent number: 5518337
    Abstract: A traffic delineator has a hollow cylindrical shell which may be of a preselected color over a preselected portion of the cylindrical shell with a wall thickness which is smaller at its top than at its bottom. As a result of the reduced weight at the top of the shell, the delineator has better recovery than delineators with constant wall thickness shells. In addition, the reduced wall thickness requires less material thereby permitting the shell to be made from a higher recovery, higher cost material, such as polyurethane. In one embodiment the wall thickness varies continuously from top to bottom and in another embodiment there is a series of steps with a constant wall thickness section between steps. The delineator has a smaller diameter base which provides rigidity and permits the delineator to be releasably supported by a support stand having a recess which releasably engages the base in a preselected orientation, held therein by a pin.

  • Patent number: 5460115
    Abstract: A temporary roadway marker having an L-shape that includes a base adapted to be attached to the roadway surface and an upwardly extending leg on which a reflective strip may be mounted is disclosed. The body of the roadway marker is formed of two materials having different flexural moduli, thus allowing the upper portion of the roadway marker to be formed of a material having a flexural modulus similar to that of the reflective strip. This helps to prevent stress concentration in the interface in between the reflective strip and the upper portion of the roadway marker, thus reducing cracks and failure of the reflective strip. In addition, it allows the base and the transition between the base and the upwardly extending leg to be formed of a more flexible material, which allows better flexing without breakage and the base to conform to the roadway surface.

  • Patent number: 5437907
    Abstract: Roadway traffic control marking tape and reflective sheeting are known in the art for providing temporary delineation and demarcation of traffic lanes in order to guide the flow of traffic through detours, construction areas and the like. Traffic channelizers and barricades are also well known in the art as barriers to discourage crossing the lanes onto the other side thereof. When work on highway lanes is completed, and traffic is redirected to newly opened lanes, the tape is generally removed. When it breaks during removal the job is particularly demanding. Damage to traffic channelizing devices which are hit by fast moving vehicles leads to their frequent replacement. Hence it has become desirable to recycle them. The recycling process requires that the reflective sheet first be removed. But the recycling process too has been hampered by the difficulty of sheet breaking during its removal.

  • Patent number: 5374137
    Abstract: A safety pole useful as a ski gate is constructed of a core of flexible, self redressing material, covered by a flexible protective mesh sleeve and capped at both ends. The core is soft and flexible enough to prevent injury to skiers, yet self redresses to its original, normally vertical position quickly and reliably. The mesh sleeve is tough and flexible, to bend with the core while protecting it from damage from skis. The end caps protect the core from damage upon insertion in the snow. By making some or all of the elements of fluorescent, brightly colored or light reflective material, or by adding reflective tape or stickers to those elements, visibility of the pole is enhanced. The pole is suitable for retaining ropes or ribbons to demarcate lift line paths, boundaries and the like.

  • Patent number: 5284326
    Abstract: The ground anchored post is made exclusively from the steel-belted treads and metallic wire rings of reclaimed, used, pneumatic tires. Each used tire is cut with a shearing tool to remove therefrom the rubber side walls thereof. A selected number of treads are then compressed flatly against one another, while a plurality of wire rings engage by their hollow the compressed pack of treads. The total number of treads selected is a function of the thickness of each tread and of the diameter of the tires, whereby the number of treads is high enough to provide taut, friction-fit engagement of the wire rings around the pack of treads. The taut engagement of wire rings around the pack of treads positively prevents the treads from engaging in sliding displacement relative to one another.

  • Patent number: 5273371
    Abstract: The novel signalling post is adapted to be mounted on a flexible base member. The post comprises an outer, hollow, substantially rigid, transparent polycarbonate tubular member. The polycarbonate tubular member has a memory for returning to its original shape upon impact. An inner opaque flexible plastic tubular member is mounted inside the transparent tubular member and has a diameter to fittingly slide inside the transparent tubular member. The opaque tubular member has substantially no memory. The polycarbonate tubular member has a memory which allows the flexible opaque tubular member to maintain a substantially rigid shape and to return to its original shape if slightly deformed upon excessive impact. The transparency of the outer tubular member allows the introduction of a colored or reflecting film between both tubular members for simultaneously displaying a visual signal through the transparent tubular member while the latter protects the film against damages.
