Definitions

  • This invention refers to an electronic system for the adjustment of stops and start-up of blind and awning automatic winding motor-reducers.
  • the adjustment of the maximum stops for lowering and raising is carried out by means of an electronic plate controlled by a micro-processor with a single pressing action in each sense, from the final users control mechanism.
  • the system is capable of adjusting the stops in such a way that cannot be cancelled from the control used by the final user.
  • German patent DE 4038923 describes a motorization for blind winders that uses a prisoner nut to activate two extreme position stops.
  • the stops are also installed on prisoner nuts so that their position can be altered by turning the screws on which they are mounted.
  • This system has two serious problems: on the one hand, the linear movement of the prisoner nut has to be transmitted to the opposite side of the motor-reducer device, which is performed by a flat metal strip that occupies space and restricts the size of the activation motor; and, on the other hand, the prisoner nut cannot move a great distance and because the micro-switches that are the extreme stops are relatively large, the assembly lacks prevision. It is also a totally mechanical device, subject to maladjustment and wear, and consequently to faults.
  • a further step in the development of mechanically controlled motor-reducers is the device described in document EP O 940 552.
  • the concept of interrupting the electric supply to the motor when the blind has reached its extreme positions has disappeared. Instead, it presents mechanical clutches that allow the motor to run in a vacuum, when the blind reaches the end of its path or meets with an obstacle on the way.
  • This device has the least electric complication with the greatest mechanical complication. Although on paper it is very attractive, its reliability over time is to be doubted.
  • document EP O 552 459 describes the use of virtual electronic stops by the use of an electronic control device in programming mode.
  • the position of blind is determined by an impulse counter.
  • the impulses are generated by a fixed Reed relay and numerous permanent magnets around the blind's winding drum.
  • the control device has a programming mode and an operating mode and, consequently, the possibility of the final consumer acting on the motor-reducer is perfectly accessible, which is in no case convenient.
  • the device described in document US 5.540.264 is possibly one of the most sophisticated systems.
  • the impulse counter is abandoned and replaced with a series of inductive end stops, the position of which on the side guides of the blind is adjustable, and which are activated by permanent magnets on the end of the blind.
  • a linear inductive sensor positioned along one of the side guides of the blind, produces an electro-driving force in proportion to its speed.
  • This system has a series of disadvantages, such as the fact that it is complicated, slow, and the stops can be cancelled by the final user's control mechanism. This can be very dangerous, because if a piece of furniture or any other object accidentally presses the control levers, the system would be out of control.
  • This system also requires the use of an independent two-lever control device, which is more costly that opposite double-lever controls.
  • the motor-reducing device that is the object of this invention solves the disadvantages previously described, providing total control over the movement of the blind, but with adjustment operations independent from the final user's control operations.
  • the motor-reducing device that is the object of this invention incorporates a linear potentiometer that is an electric, virtual representation of the blind's position.
  • This potentiometer is activated by a prisoner nut that receives the movement from a polygonal control ferrule adjusted to the inside of the blind drum, which in turn receives the movement from a matrix ferrule activated by an electric motor and a planetary reducer.
  • the device that is the object of this invention ensures, by means of the micro-processor, protection against possible accident during domestic use:
  • the motor-reducing device that is the object of this invention ensures the availability of:
  • a tube (3) is introduced, inside which the entire motor-reducing device is positioned.
  • This device consists of an electric motor (14) coupled to a planetary reducer (15) which transmits the movement to driving matrix (4) which is able to revolve around the fixed external tube (3), and is therefore liable to be coupled to the inside of the drum (17) in which the blind (18) is rolled.
  • the control ferrule (2) has internal teeth that links to a gearing (17) which is solidary with a threaded rod (19) liable to cause the movement of a prisoner nut (10), which is lodged in a prisoner nut support (23) and slides along two guides (21), transmitting the movement to a linear potentiometer (16) which thus constitutes an electric representation of the physical position of the blind.
  • a restoration micro-switch (5) is fixed to an external printed circuit and threaded rod support (6), and this end of the device is covered by the motor-reducer support (1), solidary with the external tube (3) which immobilised this assembly but allows the control ferrule (2) and the matrix ferrule (4) to turn freely.
  • Two printed circuit and threaded rod supports (6) are used for the assembly of the above mentioned items, made up of two metal plates, one of which also acts as an earthing connection, joining the printed circuit (11) on which the linear potentiometer (16) is installed to the external tube (3).
  • the electric motor (14) starter condenser (12) is installed on the internal printed circuit and threaded rod support (9).
  • the external printed circuit and threaded rod support (6) fastens the restoration micro-switch (5) to the motor-reducer, also preventing the threaded rod activating mechanism (7) from moving out of place.
  • the conventional design planetary reducer has three recurring stages, of a similar structure, to attain global reduction of 150:1.
  • Each of the stages consists of three planetary gearings (25) moved by a central pinion (27), which in turn revolve on a toothed crown (29) attached to the external tube (3) which is the casing for the motor-reducing device assembly that is the object of the invention.
  • This circular movement of the shafts of the planetary gearings (25) is transmitted to the following central pinion (27) which links to the planetary gearings for the following stage.
  • the matrix ferrule (4) is solidary with the shafts on which the planetary gearings (25) for the third and final stage are mounted.
  • Both the electric motor (14) and the electro-brake (13) are conventional and any of those available on the market can be used, with the only condition that they adjust as well as possible to the diameter of the external tube (3).
  • the printed circuit (11) contains a source of supply, a stabilising circuit and a micro-processor detection and control circuit. See figure 6.
  • the source of supply is capable of generating sufficient voltage and current to support the entire electronic system.
  • the different components used in the source of supply establish a current that will always circulate through the circuit.
  • Both the resistances R1, R2, the condenser C1 and the diodes D1, D2, D3 and D4 are in charge of this function.
  • Resistances R3 and R4 are for discharging the condenser C1 if there is no input current.
  • the stabilising circuit consists of condenser C2.
  • Condenser C3 is made of polyester and rather than to stabilise the voltage it is used to avoid possible high frequency alterations. At this point of the circuit we will have a maximum stable voltage of 15 V.
  • a conventional stabilising circuit (22) of the "7805" type stabilises the voltage at 5 V, and together with condenser C4, it avoids small signal alterations.
  • Resistances R7 and R8 are microprocessor outlets (24) with activate transistors Tl and T2. These in tun activate relays REL1 and REL2, respectively. Each relay is in charge of activating the motor in one sense or the other. In this system there is a small current absorption system. When one of the relays works, consumption is correct and therefore none of the components of the source of supply become heated. When no relay is functioning, the diodes of the source of supply could burn (not if they are of the right power rating). To avoid this, and for safety purposes, a system of T3 and T4 is installed, activated by resistances R6 and R15, which will work when no relay is functioning. They will thus drive the current through resistance R16, which will emulate the consumption of the relay.
  • the motor-reducing device that is the object of the invention works as follows:
  • the motor-reducer will be presented as a compact assembly fully mounted inside the external tube (3) liable to be fixed to a wall by its solidary support (1). See figure 1. From this compact assembly the only projections are the restoration micro-switch (5) and the matrix (4) and control ferrules (2), and this is connected by a cable to the control mechanism (20).
  • the assembly is introduced into the drum (17) of the blind (18), for which the matrix ferrule (4) has a light surface with a view to reducing the resistance produced by friction when this operation is performed.
  • the operation is completed by coupling the control ferrule (2) to the inside of the drum (17).
  • the motor-reducer support (1) is attached to the wall by a set of screws, as can be seen in figure 4, thus immobilising the assembly.
