  • Patent number: 9951487
    Abstract: A selectively activated speed bump is placed on streets to slow down vehicles. The cover has a central part and lateral parts on both sides of the central part. An elevation movement mechanism for the cover is installed in a rectangular pit formed by a box. A shaft has a terminal end joined to pillow blocks inside the box and a plurality of cams, being flexible offset discs, along a length of the shaft. The cams turn to raise the cover to a higher level than the ground and continue to turn in order to return the cover to the same height of the ground. The speed bump slows vehicles on streets and on avenues.

    Abstract: A three dimensional (3-D) thermoplastic pavement marker and the application thereof to roads, streets, walkways and other paved surfaces is described. The marking patterns are composed of two or more independent sections, the first section is a grid representing for example, the mortar joints in a brick wall. The second sections or inserts, for example, can represent bricks which are contained within the grid. By varying the measurements in height of the brick component (first section) and the grid component (second section), a three-dimensional pavement marking pattern is created. This article of manufacture allows for enhancements in beautification and preservation of historical pavements as well as the introduction of safety/warning devices using the same or different pavement marking patterns.

    Abstract: The automatic speed bump is installed in a roadway to discourage motor vehicle travel at excessive speeds. The device includes a box-like structure set into the surface, the box having upper edges flush with the surface. Two doors are hinged to the box along their opposite edges. Concentric spring and shock absorber assemblies lift the centers of the doors to create a speed bump. A guide strut is installed between each spring and shock absorber assembly to maintain alignment of the apparatus. The springs and shock absorbers retract at a predetermined rate when a standard motor vehicle encounters the raised doors at a reasonable speed. The doors folding flush with the surface to allow the vehicle to travel over a flat surface. The shock absorbers cannot retract faster than their predetermined rate, resulting in the doors remaining raised when a vehicle travels over the device at higher than reasonable speed.

  • Patent number: 8730063
    Abstract: A fail-safe circuitry for a vehicle barrier security system prevents accidental raising of the barrier due to inadvertent closing of an activation relay causing power to be provided to an activation mechanism raising the barrier. A latching relay, having a latched state and reset state, is placed in series between the activation relay and the activation mechanism. The latching relay is reset whenever the OPEN switch is pressed for lowering the barrier or an automatic reset relay is energized by a controller whenever passage of a vehicle is sensed. Prior to raising the barrier, the latching relay must be reset, which can occur by pressing the OPEN switch or by the controller detecting passage of a prior vehicle and activating a automatic reset relay. Accidental raising of the barrier due to malfunctions of the activation relay due to vibrations is prevented by latching and resetting the latching relay.

  • Patent number: 7423552
    Abstract: A Warning Bump traffic safety device comprised of a base which is inserted over traffic cones or barrels and a strip and extensions, generally trapezoidal in cross section, attached to the base which extends into the roadway which causes both an audible and sensory warning to motorists driving over these strips. This traffic safety device is typically deployed in construction work zones in the buffer and work areas to provide additional warnings to both drivers as they approach a construction work area and additional warnings to both drivers and construction workers if a driver encroaches into lateral buffer area in the work zone. These traffic safety devices also tend to stabilize the cones and barrels.

  • Publication number: 20080179791
    Abstract: A base unit for a road stud is provided. In one embodiment, the base unit is made of plastic and has a recess with a plurality of projections. The projections extend over the floor of the recess for retaining a resilient insert within the recess. The base unit comprises a first portion representing the body of the base unit, and one or more additional portions fitted to said first portion, for example by adhesive bonding. Each of said projections may be formed from one or more planar elements. The base unit further has a front portion, a back portion, and opposing side walls, wherein the recess is located between the front and back portion and the opposing side walls. The underside of the front and back portions is provided with ribbing for transverse strengthening. A cavity is formed in the underside of each of the opposing side walls. A colourant may be added to the plastic of the base unit in order to colour the base unit, for example to match the colour of reflectors provided in the insert.

  • Publication number: 20070258764
    Abstract: A one-way speed bump for controlling both direction and speed of traffic is described. The speed bump has a shallow front face and a steep rear face. Vehicles approaching the front face of the speed bump are allowed to pass over the speed bump at a controlled rate of speed. Vehicles attempting to pass from the wrong direction will engage the steep rear face of the speed bump. This will cause the vehicle to be jolted and possibly damaged. Indicia may be provided on the steep rear face to warn drivers that they are traveling in the wrong direction.

  • Publication number: 20070201948
    Abstract: A metal-capped device in the form of a traffic surface adapter is disclosed, the device being arranged to be positioned on a localised area of a (pedestrian or vehicular) traffic surface 31 for the purpose of adapting (i.e., modifying) the characteristics of the surface. The device in one of its possible forms comprises a tactile marker having a plastics material first portion 20 incorporating a head 21 that is arranged in use to sit on the traffic surface. A depending projection 22 is formed integrally with the head and is arranged in use to locate within a recess 30 in the traffic surface and so retain the device in situ. Two or more spaced-apart apertures 26 are formed in the head, and a metal cap 27 is provided to overfit the head. The metal cap has depending tabs 37 that are shaped and positioned to project through the apertures 26 in the head and to be folded under the head to hold the metal cap captive to the head.

  • Patent number: 7249911
    Abstract: A novel small quasi-hemispherical truncated-dome modular-dot like device, which can be readily affixed to pavement in a Federally-mandated pattern via a special hole/matrix-stencil;—the resulting demarkations thereby serving to alert the Legally-blind (as well as Guide-dogs, persons in wheelchairs, and otherwise pre-occupied non-handicapped individuals) their pedestrian-pathway is entering into a potentially dangerous transition area typically crossed by a motor-vehicle pathway. The individual so called DW-DOTS™ are resilient circular low-profile devices having an annular-ramp configuration, and thus standing out only sufficiently above a foot-surface as to enable foot-tactile detection, yet not pose the potential tripping hazzard known to embedded-mats. This novel safety-button offers a desired permanent contrasting-color, plus has a definition and rugged permanency not known to poured-dot installations.

  • Patent number: 7188825
    Abstract: A catchment net (1), especially for rockfall blocking, includes a net (2) consisting of elements that engage with each other, and whose two longitudinal sides are each moveably held by a holding rope (3, 4) extending between at least two support bodies (7, 8, 9, 10). The two holding ropes (3, 4) are moveably held by the individual support bodies (7, 8, 9, 10) in their longitudinal direction and tensioned at the side. At least one running rope (37, 38, 39, 40; 47, 48, 49, 50) or suchlike extending alongside the support body on each of the holding ropes (3, 4) preferably within the area of the each support body (7, 8, 9, 10) is affixed with one end on one side and with the other end on the other side to the support body (7, 8, 9, 10). The net (2) is moveably held within the support body area by the running ropes (37, 38, 39, 40; 47, 48, 49, 50). The catchment net (1) therefore guarantees an optimal load distribution as well as a more favorable flow of energy through the net.
