Abstract: Material for a sign support structure, such as a signpost, providing greater visibility an added awareness to the sign comprising a film or sheeting on which is printed contrasting colored segments or contrasting colored designs, words, or letters replicated repeatedly on or within and along the length of the material. The material, when attached to the sign support structure or an independent substrate that is subsequently attached to the sign support structure, provides a higher visibility pattern drawing awareness to the sign.

Abstract: A system and method for obscuring road signs by applying an opaque adhesive-backed film to the signs from a roll containing the film. The film and adhesive may be able to conceal sign details sufficiently with only one or two layers of film. The film may be pressure-applied with an adhesive selected so as to adhere sufficiently to the signs or to other layers of film without leaving adhesive or other residue on the signs once removed. The film may be perforated at predetermined intervals to facilitate separation, and the system additionally or alternatively may include a cutter to permit the user to separate the film wherever desired. Various polymers may be used for the film, including polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polypropylene, low density polyethylene (LDPE), polyester, polyolefin, or other coextruded (CoEX) polymer films. Similarly, various adhesives, including latex-, acrylic-, rubber-, or silicone-based adhesives may be used.

Abstract: The present invention relates to a post (12) made of a first material (2) comprising an element (13) made of a second material that is softer than the first material. The element is partially embedded in the first material and has a front surface (6) that forms part of the surface of the post. The element comprises in a cross section perpendicular to the longitudinal axis of the post a front portion (8′) including the front surface and a rear portion (9′). The element is designed so that a waist (w1, w2) is formed between the front and rear portions. The front portion is tapering towards the waist and at least a part of the rear portion has a width larger than the width of the waist.

Abstract: A bollard sleeve with a removable or replaceable cover is described. In one example, the bollard sleeve includes a cover portion and a sleeve portion coupled to the cover portion. The cover portion can have a cover removably coupled to a skirt, and the sleeve portion can have a tab. When the tab is in a first position, the tab can prevent the cover from being removed. When the tab is in a second position, the tab can form an opening that allows the cover to be removed. The tab can be bent from the first position to the second position, or the tab can be removed from the sleeve portion.

Abstract: There is disclosed a pole support for removably supporting a hollow tubular pole, wherein the pole has a latching recess provided along its length. The pole support includes a housing defining a socket that is open at its operative upper end for receiving the pole. A latch is located within the socket and is mounted on a pivot to be pivotally movable between a latched position and an unlatched position. The latch has a latching arm extending on one side of the pivot and a ballast arm extending on an opposed side of the pivot, wherein a centre-of-weight of the latch is located off-centre from the pivot in the ballast arm so that ballast arm normally biases latch under gravity into its latched position.
