20090103988 | RETAINING WALL AND BLOCKS FOR THE FORMATION THEREOF - A block having at least one front face, at least one back face, sides connecting the front and back faces, a top surface, a bottom surface and at least one cavity passing through the entire height of the block from the top surface to the bottom surface, wherein the cavity is positioned so that the centre of mass of the block lies closer to the back face than does the geometric centre of the block. | 04-23-2009 |
20100192482 | FRANGIBLE POSTS - A method of producing a frangible post characterised by the step of forming a region of weakness by compressing a portion of at least one surface and/or edge of the post. | 08-05-2010 |
20120037867 | BARRIERS - A barrier is provided, including opposed longitudinal side members separated by a gap, supports which hold the side members above the ground; and at least one U-shaped member when viewed in transverse cross section which is/are connected to the opposed members to span between the gap and wherein the at least one U-shaped member does not contact the supports. | 02-16-2012 |
20120056143 | POSTS - A terminal post for a barrier includes an upright portion having an aperture positioned, so that in use: the aperture is located in a region of the upright portion above a ground engaging portion of the upright portion; and wherein located on one side of the aperture is a transverse reinforcing member which includes a slot for receiving a cable. At least one groove, or pair of notches is provided located beneath the aperture, and form(s) a predetermined fail line, along which the post will deform, upon receiving a substantially inline impact, which causes the transverse member to move to release the cable, and wherein the aperture is dimensioned to allow the terminal end of the cable formally retained by the slot to pass therethrough. | 03-08-2012 |
20120118690 | ENERGY ABSORPTION DEVICE - An energy absorbing device having a shell comprising at least one external wall defining an internal area, wherein said internal area is further defined by one or more interior wall(s) spanning across at least a portion of said internal area, between opposing sections of said external wall(s). | 05-17-2012 |
20130081348 | PLASTIC BARRIERS - A temporary plastic barrier section includes a plastic shell having first and second plastic connection portions integrally formed on opposite ends thereof; and a rigid straight elongate member, wherein the rigid straight elongate member lies substantially adjacent to at least a portion of each of the first and second connection portions, and wherein the rigid straight elongate member includes connection points at the distal ends thereof which are configured to align substantially with the first and second connection portions. | 04-04-2013 |
20130140510 | ENERGY ABSORPTION DEVICES - A slider assembly includes:
| 06-06-2013 |
20150107947 | ENERGY ABSORPTION DEVICE - A method of absorbing energy from a moving object upon impact, where the method includes utilizing at least two types of energy absorbing elements to absorb at least some of the energy of the impact in an energy absorbing apparatus. A first type of energy absorbing element absorbs the majority of the energy absorbed by the apparatus and subsequent types of energy absorbing elements continue to absorb energy after the first type of energy absorbing element has ceased operation and can no longer absorb energy. | 04-23-2015 |
