  • Patent number: 10266999
    Abstract: A vehicle barrier apparatus includes a base and a deployable element. The deployable element is rotatably coupled to the base, enabling transition from a stored orientation to a deployed orientation. The deployable element can engage a vehicle physically in the deployed orientation to impair vehicle motion. An actuating mechanism is mechanically coupled to the deployable element cause the deployable element to move from the stored orientation to the deployed orientation responsive to a trigger. The apparatus may include a triggering device that detects the vehicle and provides the trigger to the actuating mechanism responsive to the detection. In addition, or alternatively, the apparatus can include a communications interface that receives a trigger communication from a remote location and causes the trigger to be provided to the actuating mechanism. The apparatus may be portable.

    Abstract: A delimiter that can be arranged along the sides of a runway. The delimiter can be locked in an upright position for most normal operations. When the runway must be cleared of snow, an operator can lower the delimiters in place, either manually or by motor. After the runway has been cleared of snow, the delimiters can be raised again for use. Unlike the delimiters described above, these delimiters meet all aircraft regulation requirements. When collapsed, they do not protrude above the surface of the ground. The delimiters also have a shear mechanism that allows the raised portion of the delimiter to break off when struck. This shear mechanism protects aircraft by breaking away the upper portion of the delimiter.

  • Patent number: 6926462
    Abstract: A safety barrier for road use comprises a barrier element which can be displaced between an operative position, above the road surface, and an inoperative position, in which it does not substantially project above the road surface. Preferably provided is a number of sets of aligned barrier elements, rigidly connected to one another, the adjacent sets being connected together by articulated connecting structures which enable one set of barrier elements to be displaced between its inoperative position and its operative position without modifying the positions of the adjacent sets. In this way, one or more stretches of the barrier can be brought into the inoperative condition, leaving the adjacent stretches of barrier in the normal operative condition.

  • Patent number: 6841223
    Abstract: Composite pavement markings with improved wear resistance and other advantages are disclosed. The composite pavement markings typically include a unitary retroreflective article attached to a base pavement marking. With the composite construction, different portions of the pavement marking are provided at different heights. The taller portions of the pavement marking may preferably offer some protection to the shorter portions from wear caused by vehicle traffic and/or snowplow blades. By combining two different retroreflective pavement markings to form the composite pavement markings of the present invention, a combination of features and properties may be obtained that is provided by neither of the pavement markings alone. Methods of manufacturing composite pavement markings are also disclosed.

  • Patent number: 6805515
    Abstract: A removable traffic control bollard has a post and a base for removably receiving the post. The post has a depending cylindrical part that fits into the tube of the base, held by rider elements that fit inside an upper post member of hollow tubing. The base has a faceplate opening into a downwardly depending tube that is embedded in the ground, or the like, preferably with the faceplate at surface level. The faceplate has two locking apertures over a box, and the post has an aperture in a cleat, through which apertures a padlock U-bolt can be inserted to lock the post to the base. The post can be repeatedly inserted into the base and locked into position and, if desired, subsequently removed by unlocking it and pulling it up out of the base.

  • Patent number: 6485226
    Abstract: A method of employing a safe and effective flexible plastic curb and gutter. The method of installing a curb along the side of a road having a lower layer prior to laying a top layer of asphalt on the road comprises providing elongated curb strips each having i) a horizontal holding side portion having spaced openings cut therealong; and, ii) a uniformly continuous upright trough portion having a lower edge portion continuously attached to the outer edge of the horizontal side portion. An upper edge portion of the upright trough portion is adapted to extend above the upper layer of asphalt so that water running off the road is channelled along an inner side of the upright trough portion. The horizontal holding side portion of the elongated strip is seated along and parallel to an outside edge portion of the lower layer so when the top layer of asphalt is laid thereon adhesion between the layers through the openings therethrough hold the elongate curb strip in position.

  • Patent number: 6149340
    Abstract: Apparatus is provided for self-righting a signpost after it has been tipped over comprising a plate for connecting to the signpost and a complementary tray secured to the ground. Most of the apparatus is located below ground out of harm's way. The tray has upturned peripheral edges within which the plate resides. A chain is connected to the plate, extends through a hole in the tray and into the bore of a pipe for connecting to the bottom of a compression spring. When the signpost and plate tip, the plate rotates within the tray, displacing the chain and compressing the spring. Preferably a lip extending over the edge of the plate causes the plate to ride up the edge of the tray, increasing the chain's displacement. The increased tension in the chain urges the plate and signpost to right themselves. The plate and tray are complementary and square shape so that the square sides engage during tipping and prevent rotation of the signpost's orientation when it returns to the upright position.

  • Patent number: 6062766
    Abstract: A raised pavement marker includes a reflector assembly that is resiliently supported by a membrane, that in turn is supported by a frame. The reflector assembly includes a skirt that overlaps the membrane, thereby allowing large-area reflectors and low-angle ramp surfaces. A vent is formed between the skirt and the membrane, and this vent is resistant to clogging. Locating elements are placed on the frame of the pavement marker to assist in proper installation of the marker in a recess of a roadway, such that all portions of the frame are positioned below the surface of the roadway. Indentations allow the installer to gauge the level of adhesive in the recess.

  • Patent number: 6050742
    Abstract: A raised pavement marker includes a rigid reflector assembly that supports two retroreflectors. The reflector assembly is resiliently mounted over a base by a resilient membrane, which is secured to the base at its outer edge. When a vehicle contacts the reflector housing, downward forces supplied by the vehicle to the reflector housing deform the membrane, which allows the reflector housing to move downwardly to pavement level. After the vehicle has passed, the resilience of the membrane restores the reflector assembly to its raised position. Methods for installing and removing the pavement marker are disclosed.
