Definitions

  • the present invention relates to a ground mounted motor-driven block system for a closure wing.
  • the present invention further relates to a closure system comprising the ground mounted motor-driven block system.
  • Ground mounted motor-driven block systems for blocking, preventing or hindering an opening motion of a pivotable closure wing are known.
  • Known systems typically comprise a frame; a blocking member comprising a contact surface configured to be raised or lowered with respect to the frame, the blocking member being rotatably mounted on the frame about a pivot axis between a retracted position in which the contact surface does not hinder a pivoting motion of said closure wing and an extended position in which the contact surface hinders a pivoting motion of said closure wing; a moveable actuation rod mounted on the frame and configured to cooperate with the blocking member to rotate the blocking member between its retracted position and its extended position; and a motorized drive mechanism configured to move the moveable actuation rod.
  • Such a system is for example disclosed in US 2021/0277692 A1 .
  • the known system relies on a pivotable actuation rod which is pivotally connected to a frame on one end and is connected to the blocking member at its opposing end, in particular via a shaft extending through an elongated slot in the blocking member.
  • the blocking member is pivotally fixed to the frame on one end and its opposing end forms the contact surface, i.e. the contact surface provided by the blocking member is formed by a tangential surface.
  • a similar kind of blocking member is disclosed in WO 2021/089973 A1 , albeit with a different actuation mechanism.
  • a downside of such a blocking member is the leeway it allows for closure wing movement. More specifically, since the contact surface is in essence tracing a circular path upwards, the contact surface moves farther away from the closure wing the higher is goes. As such, once in its extended position, there is room between the closure wing and the contact surface which is undesirable.
  • An object of the present invention is to provide an improved ground mounted motor-driven block systems.
  • the ground mounted motor-driven block systems is characterized in that the contact surface is formed by a leading surface of the blocking member when the blocking member rotates from its retracted position to its extended position, the contact surface being configured to rotate from an upwardly facing lying position to a closure wing facing upstanding position when the blocking member rotates from its retracted position to its extended position and vice versa, and in that the blocking member forms a first order lever having a fulcrum coinciding with the second pivot axis, an effort arm providing said contact surface and a load arm cooperating with the moveable actuation rod.
  • a first order lever when compared to the third order levers used in the known block systems, allows for a more accurate force multiplication control.
  • the contact surface rotates over an angle of at least 60°, particularly at least 70° and more particularly at least 80° when the blocking member rotates between its retracted position and its extended position, said angle being at most 120°, particularly at most 110° and more particularly at most 100°, said angle being preferably about 90°.
  • Such angles allow to fully retract the blocking member and still obtain a near-vertical contact surface when extended thus minimizing the risk that the blocking member damages a person or vehicle passing over it.
  • the contact surface extends substantially radially outwards with respect to said second pivot axis.
  • the contact surface is substantially planar which is advantageous when retracted as there are no bumps and/or holes in the surface and is also advantageous when extended as the blocking member is then easy to use for different height differences between the frame and the closure wing.
  • the motorized drive mechanism is an electrically operated drive mechanism. This avoids the use of fuel and/or hydraulic systems reducing maintenance requirements and improving user convenience.
  • the system further comprises a drive rod which is rotatably mounted on the frame about a third pivot axis which is substantially parallel to the second pivot axis, the moveable actuation rod being interposed between the drive rod and the blocking member.
  • the blocking member is actuated by a two-rod actuation mechanism. When compared to a single-rod actuation mechanism, this avoids leeway as each connection may be pivotal and no sliding elements are required to transfer a driving motion of the motor to the blocking member.
  • the moveable actuation rod and the drive rod are substantially parallel with one another when the blocking member is in its extended position.
  • the rods are thus in or near a dead point with respect to one another causing the blocking member to be maintained in the extended position without or with minimal force exerted on the motorized drive mechanism.
  • the moveable actuation rod has a first end which is pivotally connected to the drive rod and a second end which is pivotally connected to the blocking member.
  • the motorized drive mechanism comprises a drive shaft mounted to the frame, the drive rod being fixedly mounted on the drive shaft.
  • the drive rod is thus directly driven by the motor reducing the number of parts required.
  • the blocking member comprises a circular sector, the circular sector having a central angle which is particularly between 60° and 120° and more particularly between 80° and 100°, the central angle being most particularly about 90°.
  • the moveable actuation rod has a first end which is rotatably mounted on the frame about a third pivot axis which is substantially parallel to the second pivot axis and a second end which engages the blocking member.
  • the blocking member is actuated by a single-rod actuation mechanism. This reduces the number of parts required.
  • the blocking member comprises an elongated slot extending between a first extremity and a second extremity, the first extremity being nearer the second pivot axis than the second extremity, the second end of the moveable actuation rod being connected to the blocking member at least by means of said elongated slot, wherein the elongated slot preferably extends radially outwards with respect to said second pivot axis.
  • An elongated slot ensures that there is always a connection between the actuation rod and the blocking member and avoids that a biasing member would be needed to urge the blocking member back to its retracted position.
  • the moveable actuation rod moves along said elongated slot, said movement preferably comprising a movement in a first direction during a first part of the rotation and in a second direction, which is opposite the first direction, during a second part of the rotation.
  • the motorized drive mechanism comprises a drive shaft mounted to the frame, the moveable actuation rod being fixedly mounted on the drive shaft.
  • the actuation rod is thus directly driven by the motor reducing the number of parts required.
  • the contact surface and the elongated slot are located substantially opposite one another with respect to the second pivot axis.
  • a smallest angle between the load arm and the effort arm is at least 150°, particularly at least 160° and more particularly at least 170°, the smallest angle being preferably about 180°.
  • the moveable actuation rod when the blocking member is in its extended position, the moveable actuation rod is oriented tangentially with respect to a circle about the second pivot axis. As such, a pushing force exerted on the contact surface causes no or only a minimal torque on the moveable actuation rod causing the blocking member to be maintained in the extended position without or with minimal force exerted on the motorized drive mechanism.
  • the contact surface is configured to rotate towards the closure wing when the blocking member rotates from its retracted position to its extended position.
  • first pivot axis and the second pivot axis are substantially perpendicular to one another.
  • the object according to the present invention is also achieved with a closure system comprising a closure wing which is pivotable about a first pivot axis and a ground mounted motor-driven block system as described above for blocking said closure wing. Since the closure system includes the block system, the same advantages are realized.
  • the closure system comprises a further closure wing adjacent said closure wing and which is pivotable about a second pivot axis which is parallel to the first pivot axis, the closure system being moveable between an open position and a closed position
  • the closure system further comprises a further ground mounted motor-driven block system as described above is provided for blocking said second closure wing, the ground mounted motor-driven block system being provided on one side of the closure system when the closure system is in its closed position and the further ground mounted motor-driven block system being provided on the other side of the closure system when the closure system is in its closed position.
  • the present invention generally relates to a ground mounted motor-driven block system for blocking a movement of a pivotable closure wing.
  • blocking should be interpreted broadly as resisting an opening movement of the closure wing with the aim of preventing the opening rotation of the closure wing during normal use.
  • a sufficient force is exerted on a closure wing (e.g. when someone attempts a forced entry)
  • closure wing (or a closure leaf) is used in the present specification to embrace all kinds of closure members such as doors (i.e. having a full panel), gates, etc.
  • the closure wing is pivotally attached to a support (e.g. a post, a wall, another closure wing, etc.) and is pivotable about a first pivot axis.
  • a support e.g. a post, a wall, another closure wing, etc.
  • first pivot axis is oriented vertically, but other inclined orientations are also possible.
  • ground mounted motor-driven block system will be described with reference to a double swing gate.
  • the invention should not be considered as limited to only double gates and may also be used in the context of a closure system having only a single closure wing.
  • Figure 1 shows a closed closure system having two closure wings 1 with a ground mounted motor-driven block system 6 according to the present invention being provided for each closure wing 1.
  • Each closure wing 1 is pivotally attached to a respective tubular support 2 by means of hinges 3.
  • each closure wing 1 pivots about a hinge axis which is oriented along the vertical direction 7.
  • Actuation means 4 are provided for opening or closing a respective closure wing 1.
  • each closure wing 1 may be opened manually (e.g. by a user pushing against the closure wing 1) and a hydraulically damped actuator (e.g. as disclosed in WO 2018/228729 A1 ) may be provided to close each closure wing 1.
  • Figure 1 further illustrates a ground surface 5 in which the ground mounted motor-driven block system 6 is placed.
  • the block system 6 is shown in its blocking position in figure 1 which means that the closure wings 1 are prevented from opening.
  • the block system 6a is positioned on a first side of the closure system and acts as a stop for stopping a closing motion of the right-hand closure wing 1.
  • the right-hand closure wing 1 is provided with a gate stop 8 for stopping a closing motion of the left-hand closure wing 1.
  • a second block system 6b is provided on the other side of the closure system and blocks an opening movement of the left-hand closure wing 1.
  • the closure system is shown in its opened position in figure 2 .
  • both block systems 6a, 6b are in their unblocking position and do not (or only minimally) protrude with respect to the ground surface 5. As such, the block systems 6 do not hinder the opening or closing movements of the closure wings 1.
  • the block system 6b In order to transition from the closed position shown in figure 1 to the opened position in figure 2 , the block system 6b is moved from its blocking position to its unblocking position thereby allowing to open the left-hand closure wing 1 and subsequently the right-hand closure wing.
  • the ground mounted motor-driven block system 6a could also be replaced by a stationary block, the illustrated embodiment is advantageous since a stationary block remains protruding from the ground surface 5 and may cause injury to unaware people or may damage a vehicle passing through the closure system.
  • the block system 6a may be from its blocking position to its unblocking position at the same time as the block system 6b or it may occur at a later stage during opening of the closure wings 1 as desired.
  • the block system 6a In order to transition from the opened position shown in figure 2 to the closed position in figure 1 , the block system 6a is moved to its blocking position and the right-hand closure wing 1 is closed. Both movements may occur simultaneously or sequentially as long as the block system 6a is in its blocking position when the right-hand closure wing 1 is nearing its closed position. The left-hand closure wing 1 is closed with some time delay after the right-hand closure wing 1. Once both closure wings 1 are closed, the block system 6b is moved to is blocking position.
  • closure wings 1 in the system shown in figures 1 and 2 may be replaced by a fixed wing.
  • a double swing gate may be provided with two block systems on the same side and a stationary block on the opposing side against which each closure wing abuts when closed. This avoids having to provide the gate stop 8.
  • a double swing gate may be provided with four block systems, namely two on each side of the closure system. Other configurations are also possible.
  • a first embodiment of a ground mounted motor-driven block system 300 according to the present invention will be described by reference to figures 3A to 3C .
  • the block system 300 comprises a frame 302 having a cover plate 304 at its top.
  • the cover plate 304 is meant to sit flush with the ground surface 5.
  • An elongated slot 306 is provided in the cover plate 304 and is provided to allow a blocking member 308 to protrude therethrough.
  • the blocking member 308 is generally pivotally mounted to the frame 302. In the illustrated embodiment, this is achieved by providing a shaft 310 on the blocking member 308 with mounting brackets 312 to fix the shaft 310 to the frame 302. Bearings may be provided between the mounting brackets 312 and the shaft 310.
  • the shaft 310 thus forms the pivot axis of the blocking member 308. It will be readily appreciated that other mechanisms are possible to pivotally mount the blocking member on the frame.
  • the block system 300 further comprises an actuation mechanism to rotate the blocking member 308 about its pivot axis from its retracted position (shown in figure 3A ) to its extended position (shown in figure 3C ).
