Definitions

  • the present invention relates generally to an actuating mechanism or assembly and in particular to an actuating mechanism or assembly for controlling operation of a movable member adapted for movement between a first and second position.
  • the movable member may cause operation of a device or be connected to another movable member for causing operation of a device.
  • the present invention relates to an actuating mechanism having a movable member which is not only caused to move by the mechanism but which also preloads the mechanism when it moves, so as to assist in further movement of the movable member. Movement of the movable member is both controlled by the actuating mechanism and assists in operation of the actuating mechanism, such as for example to reset or rearm the mechanism.
  • the present invention relates to an actuating mechanism having an arming device movable between two positions which when moving in one direction arms the device to further assist in control of the movable member.
  • the present invention finds particular application as a low cost, simple, low energy and compact actuating mechanism for controlling operation of diverse devices, such as for example the opening and closing of barriers, gates, doors or similar, or other completely different devices. More particularly, the present invention relates to a remote controlled mechanism for causing operation of a device.
  • the present invention relates to a floor- or ground-mounted actuating mechanism having an arming member which is activated by walking over, riding over, driving over, pushing on or otherwise depressing the arming member to energise the mechanism or assembly, such as when walking, driving, riding or passing through the doorway, gateway, etc or a designated area or region when operation of some other device is required, such as the gate, barrier, etc.
  • Actuating mechanisms for the control of opening and closing of doors, gates, barriers or the like have not been entirely satisfactory in the past for a number of reasons.
  • Many farms have a large number of gates.
  • workers are required to move from one section of the farm to another section, often travelling through gates or gateways. It is undesirable to leave gates open and accordingly each time a gate is passed through it must be opened and closed.
  • workers are required to dismount from their vehicles and manually open the gates, drive through, stop, dismount the vehicle and then manually shut the gates and return to or remount the vehicle.
  • Such operation of the gates is time-consuming and inconvenient as well as allowing the opportunity for unwanted movement of stock through the gate during this operation, since stock has a tendency to follow farm vehicles, particularly if food is delivered to the stock from the same farm vehicles.
  • an aim of the present invention to provide an actuating mechanism which finds usefulness in automatically controlling the opening and closing of diverse devices, including gates, doors, barriers or the like, particularly a remote controlled actuating mechanism that not only operates the gate but also is armed or primed through use of the actuating mechanism, particularly when passing by the device for future use.
  • an actuating mechanism adapted for use in controlling and effecting operation of a movable member between a first position and a second position comprising: a driving means for effecting movement of the movable member between the first and second positions in a first direction; a control means for controlling movement of the movable member; and an arming means for arming the driving means, said arming means capable of movement between a first position and a second position such that movement of the arming means in a first direction arms the driving means in readiness for moving the movable member in use; wherein when said driving means is armed by movement of the arming means in the first direction, operation of the control means causes the driving means to move the movable member between the first and second positions in a first direction and disarms the arming means, and when said movable member is allowed to move between the first and second positions in a second direction, the control means is reset for future operation of the mechanism.
  • the mechanism of the present invention finds use in controlling operation of a gate, door, barrier, security device, or similar, such as for example to open or close the gate, etc, or both.
  • the movable member is or is connected to a door, gate, barrier, security device or similar movable device which when in one position, typically the open position, allows access through or past the gate, etc, and when in a second position, the closed position, denies access.
  • the driving means of the present invention is a device for storing energy, such as for example a spring, particularly a torsion spring or similar, more particularly a wound torsion spring under tension. Even more typically, the wound torsion spring is wound around a shaft.
  • the control means is a cam or similar and can include an associated cam contact portion arranged so that the cam and cam contact portion interact co-operatively.
  • the control means includes an electrically operated solenoid or similar, preferably a remote controlled or remotely activated solenoid for use in operating the cam and cam contact portion.
  • the cam has one, two, three or more cam lobes, preferably two cam lobes, in which one of the cam lobes is for use in connection with effecting control of the driving means to move the movable member in a first direction, and the second cam lobe is associated with movement of the movable member in a second direction.
  • movement in the first direction allows the gate, etc to open, thereby permitting access, whilst movement in the second direction closes the gate, etc, thereby denying access.
  • operation of the control means when associated with the second lobe of the cam effects operation of the spring to move the door, gate, barrier to a closed position. More typically, operation of the control means when associated with the first cam lobe permits the door, gate, barrier to move under the influence or effect of gravity to a position corresponding to an open, entry or access position.
  • the arming device is a plate mounted in or close to the doorway, gateway or in close proximity to the barrier or similar device so that movement through or past the door, gate or barrier causes movement of the arming plate to a primed or armed position thereby arming the driving means .
  • the arming plate can be operated by a person pushing on the plate when associated with a door, or by a person riding or driving over the arming plate when in a vehicle or similar.
  • the plate may be armed manually or may, if required or desired, be power-assisted for arming.
  • Figures 1(a), 1(b) and 1(c) are a series of three top rear perspective views of one form of the actuating mechanism of the present invention showing the mechanism in isolation when in three different conditions;
  • Figure 2 is an enlarged top rear side perspective view of part of the mechanism of Figure 1 in which the movable member is in a position corresponding to the closed position of the device to which it is connected;
  • Figure 3 is an enlarged top rear side perspective view of part of the mechanism of Figure 1 in which the member is in a position corresponding to the open position of the device to which it is connected;
  • Figure 4 is an enlarged top rear side perspective view of part of the mechanism of Figure 1 when in an armed or energised condition;
  • Figure 5 is an exploded rear view of the main components only of the actuating mechanism of Figure 1 shown in isolation;
  • Figure 6 is a more detailed partial top front perspective view of the mechanism of Figure 1 when the member is in a position corresponding to the closed position of the device but omitting some components;
  • Figure 7 is a more detailed partial top front perspective view of the mechanism of Figure 1 when the member is in a position corresponding to the opened position of the device;
  • Figure 8 is a bottom front other side perspective view of the torsion spring and spigot of the mechanism of Figure 1.
  • FIGs 1(a), (b) and (c) there is shown in isolation for the sake of clarity one form of the actuating mechanism of the present invention generally denoted as 2 connected to an arming plate 4 located to one side of the mechanism 2 and a bracket 6 located on the other side.
  • the actuating mechanism forms only one component of a much larger installation which can include other movable components, such as farm gates, barriers or the like.
  • a farm gate or similar (not shown) is connected either directly or through a gearing arrangement or transmission to bracket 6 and is capable of movement between two positions (closed and open) upon operation of the mechanism 2.
  • the actuating mechanism operates to move bracket 6, the farm gate or similar undergoes corresponding movement .
  • the mechanism 2 is shown in three different conditions in which the condition of Figure 1(a) corresponds to the farm gate in the closed position, i.e. bracket 6 is in a raised position.
  • the condition in Figure 1(b) corresponds to the farm gate in the opened position, i.e. bracket 6 is in a lowered position.
  • the condition shown in Figure 1(c) corresponds to the mechanism in the fully armed or energised position ready to return the gate to the closed position, i.e. bracket 6 is still in the lowered position.
  • bracket 6 adopts different positions and moves between them, the gate adopts different positions and moves between them accordingly.
  • the mechanism of the present invention is illustrated in isolation without being connected to a gate, door or similar in the interest of clarity of expression and ease of understanding.
  • mechanism 2 comprises a base plate 8 in the form of a substantially rectangular flat or arcuate plate mounted on or within a suitable enclosure as part of an overall apparatus or assembly for mounting on the driveway entrance or similar of a pathway travelled by a farm vehicle or the like.
  • a first frame member 10 (shown only in Figure 5) is located along one side edge of plate 8 and a second frame member 12 is located along an opposed side edge of plate 8.
  • many components such as frame member 10 (shown only in Figure 5) or slotted wheel 84 (introduced later) have been omitted from many of the drawings for clarity so that specific arrangement of components forming the actuating mechanism and their respective interrelations with each other can be seen more clearly.
  • Frame member 10 is provided with a circular recess 14, for receiving large plastic washer 16 having a flange 18 acting as a bearing for one end of main axle 20 whereas the other frame member 12 is provided with a circular recess 24 for receiving small plastic washer 26 having flange 27 acting as a bearing for the other end of main axle 20 which extends between the two opposed frame members 10, 12 so that main axle 20 is journalled in the plastic washers and apertures 14, 24.
  • main axle 20 is shown only partially in all of the figures for the sake of clarity but in reality extends from frame member 10 to frame member 12.
  • Housing 28 is provided at or towards the rear of base plate 8 and houses an electrically operated solenoid, remote control signal receiving unit, a power source such as a battery, and any other ancillary equipment required to activate the solenoid. Housing 28 may be sealed to protect the working of the solenoid.

  • the other of the prongs 52b of the mating discs 46 is received in recess 56 of the spring recess of the T- catch spring closest to the stop to allow the spring 64 to pivot in use of the mechanism 2 along with corresponding movement of the T-catch 56 whilst maintaining pressure of the T-catch so that the cam contact portion 62 is in contact with the lobes of cam as required.
  • cam contact portion 62 rests on part of the cam surface adjacent the lobes and adopts a relatively lower position.
  • the T-bar is forced to ride up along the lobe to adopt a relatively elevated position which operation will be described in more detail later in this specification.
  • a generally eccentric-shaped arming disc 66 is located on main axle 20 between mating disc 48 and small washer 26 by main axle 20 being received through the central aperture of the arming disc so that the arming disc is able to rotate about the main axle as required.

  • a remote transmitter is operated thereby sending a signal to a receiver located within housing 28 together with a suitable power source such as a battery which provides energy for operation of solenoid to retract solenoid pin 30 within housing 28.
  • a suitable power source such as a battery which provides energy for operation of solenoid to retract solenoid pin 30 within housing 28.
  • the power source need only be sufficient to operate the solenoid, since operation of the game or similar is by the preloading tension in the actuating mechanism caused by the tension spring being armed or under tension.
  • link 34 is moved towards housing 28 thereby rotating crank arm 38 of cam 40 towards the housing 28 which in turn permits bar 60 of the T-catch 66 to ride up along the first lobe 42 thereby releasing the end of bar 60 from the shoulder stop 68 thus releasing the slotted wheel 84 to rotate in an anti-clockwise direction under the effect of gravity on the gate.
  • the gate is so hinged that it is biased for opening when free so that the bias or weight of the gate causes it to move to the open position.
  • the vehicle may be driven through the gate and over the arming plate 4 which is connected via spigot 72 to arming disc 66 and spring 78.
  • arming disc 66 As the vehicle passes over the arming plate 4 it is depressed further towards the ground against the bias of torsion spring 78 which is put into compression by the action.
  • spigot 72 moves within arcuate slot 74 due to the depression of arming plate 4, the arming disc 66 is rotated anti-clockwise until the shoulder stop 68 rotates past and under bar 60 to clear the bar whereupon it is pushed down by spring 64 to engage against the shoulder stop.
  • cam 40 is more or less fixed because it is connected to the solenoid pin 30 by link 34, when bar 60 falls with the barrier the cam contact portion 62 of bar 60 adopts a position on the approach to second lobe 44.
  • the second lobe can release the stored energy to close the gate when required.
  • the remote transmitter When the vehicle passes through the gate and the gate is to be closed, the remote transmitter is operated so that the solenoid pin 30 is retracted into housing 28. On retraction of the solenoid pin, crank arm 38 of cam 40 is rotated towards housing 28 which in turn moves second lobe 44 which forces the cam contact portion 62 of bar 60 to ride up second lobe 44 so that the extreme end of bar 60 is released from being held captive in rebate 82.
  • Advantages of the present invention include a low cost, self-contained, compact, reliable actuating mechanism for use in remote locations for automatically closing gates and the like.
  • the gate may be opened and closed without the need for the operator to dismount or alight from the vehicle.

Abstract

Ce mécanisme d'actionnement (2), qui sert à actionner une barrière, une porte ou toute autre installation similaire, actionne un élément mobile (6) qui est relié soit directement soit indirectement à un autre dispositif, pouvant être une barrière ou une porte. Ce mécanisme d'actionnement (2) comprend une plaque amorce (4), qui, en se déplaçant, précharge ou arme un élément d'entraînement, tel qu'un ressort à torsion, entraînant le mouvement de l'élément mobile (6), lorsque ce mouvement est demandé par l'actionnement d'un élément de commande ayant la forme d'un solénoïde à activation électrique (30) et d'un système de came (40). Ce mécanisme d'actionnement a l'avantage de ne pas nécessiter d'énergie pour le déplacement de la barrière ou de la porte, mais de ne nécessiter d'énergie que pour le déplacement du solénoïde, dès lors que le mouvement de la plaque amorce, sous le poids d'une personne marchant ou d'un véhicule roulant sur la plaque, charge le ressort et le soumet à une tension supérieure qui entraîne le mouvement de la barrière, de la porte ou de toute autre installation similaire.
