Definitions

  • the present invention relates to an apparatus for controlling pivoted closing systems, the latter encompassing systems with one or more wing, such as doors, street doors, gates and the like, as well as systems of the mobile barrier type, equipped with drive means for opening and closing movements.
  • one or two wings, or a barrier are made to rotate about an axis which is vertical for wing systems and horizontal for barrier systems, by corresponding actuators whose configuration varies according to the type of closing system used.
  • linear actuators In the case of wings, that is to say, for driving street doors, doors or gates, linear actuators are used, i.e.: actuators with at least one element whose length may vary depending whether the wing is open or closed.
  • a motor connected by a chain or similar transmission means to a set of toothed wheels is envisaged, the final toothed wheel acting upon a shaft at the barrier pivoting axis.
  • a mobile structure In both types of pivoted closing systems, with wings or barriers, a mobile structure is used which rotates about a pivoting axis on the structure itself usually covering an angle of 90°. For this reason, the system drive means are activated, during opening and closing operations, for a period of time which corresponds to the movement of the mobile structure between two end positions, separated by an angle which corresponds to the structure's travel about the pivoting axis.
  • the following devices are amongst those envisaged to stop the drive means on the closing systems: mechanical, electromechanical or electronic clutches, able to cut off the power supply to the motor when there are variations in motion, that is to say, when the mobile closing structure stops because it has reached the end positions.
  • Such devices consist, for example, of microswitches positioned on the arm of electromechanical actuators.
  • by-pass valves may be envisaged, to check, by means of pressure variations, the completion of wing closing or opening operations.
  • the servo controls for wing closing systems are equipped to operate rapidly at intermediate angles and slowly at the start and end of the opening movement, so as to prevent the moving structure from jolting or being struck: for this purpose, in the case of electromechanical actuators, a pair of microswitches is envisaged on a bar which is fixed to the actuator assembly and extends parallel with the worm screw whose interception determines a variation in the motor control speed, this being a function of the angle selected for low speeds. These microswitches must have electrical contacts which are connected to the rear of the motor, at the point where it is attached to the fixed part of the fitting (of suitable size, with space for the passage of the necessary cables, etc.).
  • end of travel damping occurs by throttling the hydraulic flow at the two ends of the actuator travel: to obtain slowing, the actuator must cover its entire travel, since there is a mechanical link between slowing and the length of the actuator, defined by the position of the throttling at the said ends.
  • the aim of the present invention is to overcome the afore-mentioned disadvantages with an apparatus for controlling pivoted closing systems, such as means for the activation of the mobile closing structure drive means, two cam elements, whose active profile lies parallel with the structure's axis of rotation, attached to a support which is fixed to the axis itself and separated by an angle which is determined according to the preset value, and cam element interception means, fixed to the mobile structure, which interact with the cam elements in a direction parallel with the axis, and may have at least two configurations, so as to allow the drive means to pass from a first to a second speed.
  • an apparatus for controlling pivoted closing systems such as means for the activation of the mobile closing structure drive means, two cam elements, whose active profile lies parallel with the structure's axis of rotation, attached to a support which is fixed to the axis itself and separated by an angle which is determined according to the preset value, and cam element interception means, fixed to the mobile structure, which interact with the cam elements in a direction parallel with
  • An apparatus made according to the present invention may be applied to newly manufactured or installed opening systems, or can be fitted to pre-existing opening systems by means of simple modifications.
  • an apparatus for controlling the movement of pivoted closing systems may be used on systems consisting of a mobile structure 2 which pivots about an axis X.
  • Figure 1 is a schematic representation of an opening system for a door with two wings 2, pivoted on respective vertical axes X.
  • the mobile structure is represented by a barrier 2, pivoted on a horizontal axis X.
  • the width of the mobile structure corresponds to the gap L of an entrance or passage.
  • the structure is fitted with drive means 4, connected to the structure by transmission means 6 suited to the type of movement: a linear actuator is envisaged for a wing closing system, whilst flexible connections such as chains combined with toothed wheels are envisaged for a barrier closing system.
  • the transmission means 6 are not described in detail in this text, since they do not concern the object of the present invention.
  • the drive means 4 are controlled by controls 1' which act upon the drive means' power supply circuit, so that the mobile structure 2 can be set at a first I and second II end position, separated by an angle corresponding to a preset value ⁇ (normally 90°), said end positions corresponding to the closure or opening of the entrance or passage L.
  • controls 1' which act upon the drive means' power supply circuit, so that the mobile structure 2 can be set at a first I and second II end position, separated by an angle corresponding to a preset value ⁇ (normally 90°), said end positions corresponding to the closure or opening of the entrance or passage L.
  • connection between the drive means 4 and the controls 1' is illustrated schematically only in the embodiment in figure 3.
  • the embodiment in figure 8 shows the terminals 4' for connection to the drive means.
  • the controls 1' consist of two cam elements 11 and 12, whose active profile lies parallel with the axis X (denoted X12 in the accompanying drawings).
  • the cam elements 11 and 12 are attached to a support 10 which is fixed to the axis itself, and are separated by an angle ⁇ ' which is a function of the preset value ⁇ which defines the angle between the two end positions I and II of the mobile structures 2 (the said value ⁇ ' coincides with ⁇ in the examples).
  • Interception means 13 for the cam elements 11 and 12 are also envisaged, said means being secured to the mobile structure 2 and interacting with the cam elements in a direction X13 parallel with the axis X, and having at least two configurations, so as to allow the drive means 4 to pass from a first to a second speed.
  • the interception means 13 may consist of at least one switch, set so that it is triggered in a direction parallel with the axis X, which will be vertical for wing systems and horizontal for barriers pivoted on a horizontal axis.
  • the switch 13 may act directly upon the cam elements, as shown in the embodiments in figures 3 and 5, or by means of a connecting lever 13', as shown in figure 8.
  • cam elements are attached to the structure 2 and the interception means are attached to the axis X or a fixed point with respect to the said axis, is technically equivalent.
  • Such a variation may consist in a variation from a higher speed to a lower speed, or the stoppage of the drive means 4.
  • a first system envisages timer means 5, positioned between the controls 1' and drive means 4, and designed to disable the drive means after a preset time, following activation of the timer means by the interception means 13.
  • the mobile structure 2 is moved over a given angle at a first speed, then, following activation of the interception means 13 (by their interaction with one of the two cam elements 11, 12), the drive means pass to a second speed, lower than the first, and after a preset time are stopped by the timer means 5.
  • the mobile structure 2 is first slowed (to the second speed) and then stopped; these being the deceleration phases when opening and closing the mobile structures.
  • the cam elements 11, 12 may have an active profile H11, H12 with double height 11 - 11', 12 - 12', so that they interact twice with the interception means 13, which may consist of two switches or a switch with three positions.
  • the drive means 4 pass from the first to the second speed; at the second interaction the drive means are disabled.
  • one of the cam elements 12 is attached to the support 10 by fixing means which can be inserted in a circular seat 14; in practice, a kind of slot 14 is envisaged on the support, 10 said slot extending with a curved circumference in which the cam element 12 can be stably positioned on configurations separated from the other (fixed) element 11 by various angles, depending on the afore-mentioned preset value ⁇ .
  • the support 10 is keyed to a vertical supporting pin 7, parallel with the axis X and attached to a corresponding base 70, which may be set on the ground or at a fixed point with respect to the axis X, e.g.: a section of wall, or a fixed part of the opening system.
  • the support 10 is keyed to a horizontal pin 7, which coincides with the axis X.
  • the transmission means consist of a first toothed wheel 18, driven by the motor 4, and a second toothed wheel 10' bearing the support 10 and connected to the first toothed wheel by a chain 19.
  • the mobile structure 2 consists of a barrier 2, rigidly connected to a rod 22, connected in such a way that it may rotate, to a connecting rod 23, pivoted on the first toothed wheel 18.
  • the connecting rod 23 In its home position, the connecting rod 23 is vertical and the end pivoted on the first toothed wheel 18 is connected to the wheel 18 at a low point, diametrically opposite the point occupied when the barrier 2 is raised in the open position II, so as to avoid unwanted raising of the barrier in position I when the motor is disabled.
