Definitions

  • This invention relates to a sliding gate comprising a first gate part and a second gate part, at least one of said gate parts being slidably movable with respect to the other one between an open position and a closed position, and a locking device for maintaining each movable gate part in the closed position.
  • This invention in particular relates to a security sliding gate or a high impact sliding gate which is provided to prevent access to a particular area or to a building, and which is able to withstand a considerable direct impact on it by vehicles or tools or by any other means.
  • This invention more particularly relates to sliding gates with a total length of at least 10 m, preferably at least 25 m.
  • the first and second gate parts are placed in a position in which their respective end sides are at an intermediate distance away from one another, leaving a free passage in between the gate parts through which people and/or vehicles can access the restricted area or building.
  • the first and second gate parts are adjoining or very close to one another and are closing off the passage to the restricted area or building.
  • only one of the gate parts is slidably movable with respect to the second gate part which is not slidably movable.
  • the second gate part may for example be a fixed part of the gate, such as a post or a fence element or any fixed structure such as a wall.
  • the second gate part may also be hingedly coupled to any fixed supporting structure.
  • the sliding gate comprises a first and a second part which are both slidably movable with respect to one another.
  • the crash resistance of the existing sliding gates is not satisfactory. Especially when the sliding gates have a length exceeding 10 m, a heavy and direct impact on the sliding gate results in forces which break the locking device or severely damage the sliding gate and/or its supporting structure so that the passage to the restricted area or building is not closed off anymore.
  • the object of this invention is to provide a sliding gate having the features indicated in the first paragraph of this description, with an improved crash resistance.
  • a sliding gate comprising a first gate part and a second gate part, at least one of said gate parts being slidably movable with respect to the other one between an open position and a closed position, and a locking device for maintaining each movable gate part in the closed position, in which, according to this invention, the locking device comprises
  • Each gate part of this sliding gate comprises a respective locking body and the two locking bodies preferably are provided on different levels (at different heights above the surface on which the sliding gate is mounted).
  • the securing element can be placed in a position extending through the respective passages defined by these locking bodies and interconnecting the two gate parts.
  • a force exerted on the front side of the sliding gate (the front side is the side at the outside of the restricted area or building) is transmitted to the securing element by the two locking bodies and results in two forces acting on the securing element at different levels.
  • the securing element firmly locks each movable gate part in place and can withstand heavy impact forces without breaking. Even when the impact forces deform the gate parts, they remain in a closed and interconnected position and the forces are still transferred through the gate material to the supporting structure and/or to the foundations of the sliding gate. This results in a security sliding gate with a very high impact resistance.
  • the locking bodies and the securing element can be designed with a high breaking resistance, in accordance with the desired impact resistance.
  • a sliding gate according to the invention with a total length of 25 m and with two identical slidably movable gate parts each supported by an end post and concrete foundations is placed in the locked state, and is hit in the middle at the front side by a 12 tonne truck at a speed of 48 kms/hour.
  • the locking device withstands this heavy impact force without breaking.
  • the horizontal impact force is for example 650 kN and results in reaction forces acting on each of the two end posts : a first reaction force of about 2000 kN directed towards the other end post in the vertical plane of the gate parts, and a second reaction force of about 300 kN directed towards the restricted area or building in a vertical plane perpendicular to the vertical plane of the gate parts.
  • the reaction forces are transferred to the foundations of the gate through the material of the end posts and their supporting structures.
  • the securing pin can for example be a metal pin or rod, preferably made of steel, preferably cylindrical with a diameter of at least 70 mm, preferably with a diameter of at least 150 mm.
  • the locking bodies can be designed as plate-like parts, preferably made of metal, preferably steel, preferably having a thickness of at least 25 mm, more preferably having a thickness of at least 40 mm.
  • the passages are for example cylindrical openings in the locking bodies.
  • said first and second locking bodies are placed in a position in which their first and second passages are aligned in a substantially vertical direction, when the gate parts are in the closed position.
  • first and the second gate part comprise respective end sides which are facing each other, each first locking body protruding from the end side of the first gate part, each second locking body protruding from the end side of the second gate part, such that the first and second locking bodies are positioned in the space between the end sides of the gate parts.
  • the first sliding gate part comprises at least two first locking bodies positioned above one another with an intermediate space in between them, and the second sliding gate part comprises at least one second locking body which is placed in said intermediate space when the sliding gate parts are in the closed position.
  • the first sliding gate part comprises a set of N first locking bodies positioned above one another with an intermediate space in between each two consecutive first locking bodies, such that N - 1 intermediate spaces are formed, N being an integer which is at least 2, and the second sliding gate part comprises a set of N - 1 second locking bodies placed in a respective one of said N - 1 intermediate spaces when the sliding gate parts are in the closed position.
  • the second sliding gate part comprises a set of N second locking bodies of which N-l are placed in a respective one of said intermediate spaces, and one locking body is placed above or underneath the set of first locking bodies.
  • N is an odd number, preferably 3.
  • the securing element is movable between a locking position in which it extends through said first and second passages, and an unlocking position in which it is removed from said passages.
  • the movement of the securing element can be done manually.
  • the pin can be provided with a handle.
  • the sliding gate comprises driving means for moving the securing element automatically.
  • the sliding gate also comprises driving means for moving at least one of the sliding gate parts from the open position to the closed position and vice versa.
  • the driving means for example comprise an electrical motor or are operated hydraulically. All driving means can be activated through a control device.
  • first gate part and the second gate part are both slidably movable with respect to one another in a substantially horizontal direction.
  • Each first passage and/or each second passage can be a laterally closed opening or can be a laterally open space in a locking body.
  • the opening preferably has a cylindrical shape.
  • Each passage or at least one passage can be completely surrounded by side walls (tunnel shaped or O-shaped passage) or can be only partially surrounded by side walls (passage formed by a recess in a side wall of the locking body such that the locking body is substantially C-shaped). In the latter case, two aligned C-shaped locking bodies preferably form an O- shaped passage when considered together.
  • each gate part comprises a hollow beam extending in its lengthwise direction, and a reinforcement bar, such as a metal beam, preferably a steel beam such as a H steel beam, is provided inside the hollow beam.
  • a reinforcement bar such as a metal beam, preferably a steel beam such as a H steel beam.
  • the hollow beam preferably extends along the entire length of the gate part, and for example is a botom beam of the gate part.
  • the reinforcement bar may extend along a substantial part of the length of the hollow beam or along a small part of its length.
  • the sliding gate comprises a protection element extending in front of the locking means at the front side of the sliding gate.
  • This protection element is for example a plate-like element, preferably a metal plate, for example a steel plate.
  • At least one of said gate parts comprises a first gate portion and a second gate portion, each gate portion having the total height of the gate part but extending over only a part of its total length, the first gate portion comprising a first hollow beam portion and the second gate portion comprising a second hollow beam portion, said gate portions being produced as separate items and being connected to one another such that the first and second hollow beam portions are aligned, and said gate part further comprises a reinforcement bar extending inside both the first hollow beam portion and the second hollow beam portion.
  • the gate portions can be transported separately and can be connected in situ in the vicinity of the location where the gate is to be installed.
  • the transport of the shorter gate portions is much easier than the transport of an entire gate part.
  • the hollow beam portions preferably are botom beam portions.
