  • flange 732 of U-shaped holder 730 is also attached to shackles 742 using a bolt 744 and nut 746.
  • the cable system 795a, 795b securely couples the inner cores 750 of the posts 704a, 704b, 704c to each other and to the lower plastic bumper rails 703a, 703b via U-shaped holder 730 and pins 734.
  • Each of corner post 704a, intermediate post 704c, and end post 704b are assemblies including a cap 770, an outer shell 760, and an anchoring assembly 773.
  • the anchoring assembly includes the inner core 750 and a corresponding anchoring plate 743a, 743b, 743c.
  • the anchoring assemblies 743a, 743b, 743c are similar to those described in conjunction with protective barrier 600 shown in FIG. 6 and are configured to securely attach posts 704a-c and the ends 718a-c of the lower plastic bumper rail 703a, 703b to a mounting surface 780.
  • U-shaped holder 730 of protective barrier 700 is secured and disposed between inner core 750 and anchoring assembly 743c.
  • FIG. 11 the details of the interface of the cable system 795b and comer post 704b is shown.
  • the inner components and the manner in which the lower and upper plastic rails are attached using cable system b are much the same as is described in conjunction with intermediate post 704c as shown in FIG. 10.
  • One difference is that rather than having a U-shaped holder 730 with a flange 732, cable system 795 b attaches to inner post 750 of comer post 704 bb using an L-shaped holder 782.
  • Lshaped holder 782 of protective barrier 700 is secured and disposed between inner core 750 and anchoring assembly 743b
  • protective barriers 600, 700 provide two levels of impact absorption.
  • a first level of impact absorption is provided for less forceful impacts on the lower rail (e.g., a fork truck bumping into the rail), where the lower rail flexes to absorb the impact without the cable system being engaged and then returns to its original state after the impact.
  • a second level of impact absorption is provided for impacts of greater force on the lower rail (e.g., a fork truck driving at full speed into the lower rail), where the lower rail flexes to absorb the impact and then makes contact with the cable system.
  • the cable systems for each protective barrier provide additional strength to receive the impact without allowing a breach of the barrier.
  • the bracket is an integral part of the rounded metallic end cap (e.g., the bracket and end cap are sand cast as a single integral part).
  • the cable system limits a maximum deflection of the plastic bumper rail.
  • the rounded metallic end caps may be configured to retain the ends of the plastic bumper rail in their openings when the maximum deflection is reached (i.e., the plastic bumper rail does not ‘pop out’ of the rounded metallic end caps).
  • the cable system described above includes a braided steel cable. It is noted, however that other types of cables such as nylon cables, elastomer cables, solid steel (or other metal) cables, plastic cables, or any other suitable cable material can be used.
  • the plastic bumper rail described above includes ribs. It is noted, however that other embodiments of the plastic bumper rail do not include ribs.
  • the pins describe herein are metallic pins. In other examples, the pins are plastic pins.
  • the opposite ends of the cable are fastened to the brackets using “shackles” such as the shackle 856 shown in FIG. 8.
  • the shackles 856 are attached to the ends of the cable and interact with receiving openings in the brackets to attach the cable to the brackets.
  • the cable system is described above in the context of one exemplary barrier. But the same cable system can be used to improve any number of barriers, including but not limited to the barriers and other protective apparatuses described in U.S.

Abstract

Une barrière de protection comprend une première pièce d'extrémité configurée pour être ancrée et fixée à une surface, une seconde pièce d'extrémité configurée pour être ancrée et fixée à la surface, un rail s'étendant entre la première pièce d'extrémité et la seconde pièce d'extrémité, et un câble s'étendant à travers le rail et ayant une première extrémité fixée à la pièce d'extrémité et une seconde extrémité fixée à la seconde pièce d'extrémité. Le rail a une première extrémité couplée mécaniquement à la première pièce d'extrémité et une seconde extrémité couplée mécaniquement à la seconde pièce d'extrémité.
