As the load is taken up in the slings it bears on the pivot pin and the locking pin which transfer the force into the first gate retention means 16 and second gate retention means 18. Due to the forward moment of the vehicle the first and second gate retention means 16, 18, in particular the upright plates 28, 28A thereof, will deform slightly so as to bear directly on the weights 37, 70.
  • the surface mount security gate system comprises two further optional features which may be used or may be omitted dependent on the level of risk that is needed to be mitigated against, i.e. the mass or speed of vehicles against which the gate is intended to protect.

Although it is not necessary to cover the base plate force transmission member 40, doing so will protect it against wear and reduce any trip hazard it may pose.
  • the gate 20 In use, when the gate 20 is impacted, as the central portion of it between its two ends 24, 46 will deform in the direction of travel of the vehicle. This results in the force being transmitted to the gate retention means 16, 18 and therefore the first side support 12 and a second side support 14 and the weights thereon, imposing a rotational force thereon. While for slow speed or lighter vehicle impacts this rotation may be substantially prevented by the mass of the gate system, the use of the base plate force transmission member 40 effectively tethers the baseplates to one another towards their second ends transferring any opposing rotational force between them so as to prevent or mitigate rotation of the first and second side support under impact of the gate 20.

  • each gate member Spaced along the length of and adjacent to, but spaced from, the upper face 154 and lower face 156 of each gate member are a plurality of steel pins 58, 58A extend from one side face of the gate member to the other, substantially perpendicular to the longitudinal axis of the first and second gate members 152A, 152B (although it will be appreciated that other orientations could be used), thereby creating space between the pins and the upper 154 and lower 156 faces.
  • a first flexible reinforcement member 160A in the form of a sling extends along the length of the of the first gate member 152A substantially from one end to the other.
  • the sling comprises a webbing sling rated at 10 tonnes that forms a loop, either by construction or by stitching.
  • the sling is located in the gate member 152A so that it passes along the top edge of the member 152A in the space between the pins 158 and the upper face 154 thereof, around the tubes 162, 164A and along the bottom edge of the member 152A in the space between the pins 158A and the lower face 156 thereof.
  • a second flexible reinforcement member 160B in the form of a sling extends along the length of the of the second gate member 152B substantially from one end to the other.
  • the sling comprises a webbing sling rated at 10 tonnes that forms a loop, either by construction or by stitching.
  • the sling is located in the second gate member 152B so that it passes along the top edge of the second gate member 152B in the space between the pins 158 and the upper face 154 thereof, around the tubes 162, 164B and along the bottom edge of the member 152B in the space between the pins 158A and the lower face 156 thereof.
  • each gate member 152A, 152B may also be provided with a respective first and second central flexible reinforcement member as described herein above in relation to the first embodiment, each said central flexible reinforcement member extending along the length of the gate member 152A, 152B and passing around the first and second tubes 162, 164A, 164B, such that when the gate is secured in the first position the central flexible reinforcement members extend between the pivot members 122 and the locking pin 180 substantially centrally in the gate member.
  • both the first and the second central flexible member pass around the locking pin such that the locking pin transfers force from the first gate retention means to the second gate retention means through first and second central flexible members via the locking pin 180.
  • the first and second gate members are each manufactured in substantially the same manner as the gate member of the first embodiment described above.
  • weights used in the second embodiment are as described above in relation to the first embodiment.
  • the barrier prevents or substantially mitigates against, penetration by a moving vehicle from a direction of attack.
  • the locking pin 180 may be removable from the gate members to allow them to be raised and lowered or, alternatively, the locking pin 180 may be attached to the first gate member 152A so that when the second gate member 152B is in the first position, actuating the ram 150A to raise the first gate member 152A lifts the locking pin 180 out of engagement with the second gate member 152B.
  • the arrangement of the second embodiment has the advantage that a reduced vertical height is needed to raise the gate and due to the reduced length of each gate member 152A, 152B. Further, due to the reduced length, and therefore weight, of the gate members 152A, 152B, a lower powered ram 150A, 150B and hydraulic system can be used.

Abstract

La présente invention concerne un système de porte de sécurité à montage en surface (10). Le système (10) comprend un premier et un second support latéral (12, 14) destinés à une porte ouvrable (20), chaque support latéral (12, 14) ayant une plaque de base (42, 68) dotée d'un premier et d'un second moyen de retenue de porte (16, 18) respectifs s'étendant vers le haut à partir de celles-ci. Une porte (20) s'étend entre les premier et second moyens de retenue de porte (16, 18) et est fixée de manière pivotante au premier moyen de retenue de porte (16) par un premier élément de pivot (22) au niveau d'une première extrémité de celui-ci de telle sorte qu'elle peut pivoter depuis une première position dans laquelle elle s'étend entre lesdits premier et second moyens de retenue de porte (16, 18), et une seconde position dans laquelle elle s'étend vers le haut à partir d'au moins lesdits premiers moyens de retenue de porte (16). La porte (20) est constituée d'au moins un premier élément de porte sensiblement creux (52) doté d'un premier élément de renforcement flexible (60) s'étendant entre le premier élément pivot (22) et une seconde extrémité de celui-ci de telle sorte que, lorsque la porte (20) est dans la première position, l'élément flexible (60) forme un trajet de transmission de force entre des premier et second moyens de retenue de porte (16, 18). Des poids (36, 70) sont situés au-dessus de chaque plaque de base (42, 68) et sont positionnés de manière adjacente aux premier et second moyens de retenue de porte respectifs de telle sorte que, sous l'impact, une force est transférée depuis les moyens de retenue de porte (16, 18) dans les poids respectifs (36, 70).
