  • 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.

  • Patent number: 5267523
    Abstract: A signalling panel comprises two superposed transparent plies of plastic material peripherally secured together. The plates have a cylindro-convex configuration and the two plies are slightly spaced from each other to provide a slot therebetween for receiving a flexible sheet displaying a visible information through the two plies. The panel when narrow is secured to a rigid base while when wide is contemplated to be secured to a flexible base member.

  • Patent number: 5215400
    Abstract: A quick disconnectable base support assembly for roadway sign is adapted to facilitate the removal of a sign post from a ground retaining foundation. The assembly comprises a C-shape bracket adapted to be horizontally secured to ground retaining foundation. The bracket has a flat face and two terminal flanges at each end extending one towards the other over the flat face. The plate is slidingly mounted in the bracket which has a spring leaf under one of the flanges to abut the plate against the other end of the bracket. A brace member is secured on the flat plate and is provided with an attachment for holding a sign post. With such an arrangement, the sign post can be quickly disconnected from the ground retaining foundation into which the bracket is set. This arrangement allows the transportation and storing of the sign post without any of the usual base member which are heavy and cumbersome.

  • Patent number: 5214886
    Abstract: A breakaway connection is mounted between a lower and an upper post section for upstandingly supporting the upper section on the lower section. The breakaway connection has a U-shape cross-section with lateral flanges. A weakened linear section extends horizontally on the flanges and partly on the U-shaped portion and is adapted to break upon a lateral impact. The linear section extending downwardly into folds between the flanges and the U-shaped portion of the connection for allowing the upper part of the connection to tilt backwardly while both the upper and lower parts of the connection remain linked together.

  • Patent number: 5171108
    Abstract: A ground anchor adapted to be driven into the ground comprises an elongated flat plate having a first bent portion at one end forming a U-shaped throat along one side of the plate and a second bent portion at the end opposite the first mentioned end slightly inclined relative to the flat surface of the plate in the direction opposite the throat. A cable is secured at one of its ends, to the plate, at an intermediate portion between both ends of the plate. The intermediate portion is located in the direction of the second bent portion relative to the center of gravity of the plate. The end of the cable forming a closed loop has an aperture adjacent the plate and on the same side of the plate as the throat. The loop and the throat are adapted to upstandingly retain the rod while the latter is impacted for driving the anchor into the ground, and the plate is adapted to tilt about the loop when the cable is pulled upwardly thereby imparting a plowing effect of the plate in the ground.

  • Patent number: 5160111
    Abstract: The novel collapsible signalling post is provided with a weakened section characterized by an helical groove carved on the periphery of a tubular member to mounted between an anchoring member and a rod member supporting a sign. The groove provides a weakened section adapted to split open along a portion thereof and upon bending caused by a lateral force exerted on the signalling post, the two end portions of the tubular member remain connected to each other by the unfolded spires formed between the helicoidal thread.

  • Patent number: 5090348
    Abstract: The invention is a traffic signalling post which comprises a flexible rod member, a rigid shaft coaxially secured at one end to the rod member, an anchor bore member adapted to house the shaft for maintaining the latter in a vertical position. The bore member has a perforated elastic diaphragm for peripherally sealing the shaft at a location adjacent the rod member when the latter sits in the bore member. The diaphragm is particularly characterized by a pair of rectilinear lips extending upwardly and adapted to be depressed downwardly with the introduction of the shaft in the anchor bore member and to be raised upwardly by the retraction of the shaft from the anchor bore member.

  • Patent number: 5010698
    Abstract: An anchoring post adapted to be inserted in the ground is made of a hollow tube having two laterally slanted channels inside the tube adjacent its bottom end. A bifurcated element having two prongs is adapted to be pushed downwardly in the tube, in the ground through the channels until the prongs project outwardly and laterally for retaining the tube in the ground.
