Definitions

  • the invention relates to electronic locks for doors, safes, vehicles etc.
  • a disadvantage of locks of this type is in a power coupling between the bar and the control element, which coupling is performed via a sufficiently powerful electromagnet. Because of a high power consumption of such a lock it may operate only from external mains, or energy-intensive battery.
  • EP-A-0 299 642 discloses an electronic lock comprising a bar, a bar shift mechanism and an electromechanical catch as blocking device.
  • the electromechanical catch includes adjacent electrostatically interactive elements which are mounted so as to be selectively either capable of mutual shifting or electroadhesively fixed.
  • the catch is coupled to a limiter blocking the shift of said bar.
  • An object of the present invention is to provide an electronic lock with an improved electromechanical catch using electrostatically interactive elements.
  • an electronic lock comprises a bar, a bar shift mechanism and an electromechanical catch as blocking device, said electromechanical catch including adjacent electrostatically interactive elements mounted so as to be selectively either capable of mutual shifting or electroadhesively fixed, said catch being coupled to a limiter blocking the shift of said bar, a first of the interactive elements is fixedly mounted whereas a second of the interactive elements is movable relative to the first element in a direction parallel to the surfaces of the two adjacent elements, and the limiter is drivingly coupled with the movable second element.
  • This invention provides a reduction of power consumed by the electronic lock.
  • Fig. 1 to 3 shows, in a schematical view, locations of main units of the electronic lock in different phases of its operating.
  • An electronic lock includes a bar 1, a bar shift mechanism consisting of a bolt 2 and a control lever 3 having a peg 4.
  • a vertical hole (marked on the local cross-section) is made in a body of the bolt 2, in which hole a cylindric pin 7 is inserted having a transversal tip 5 going out of a slot in the lower plane part of the bolt 2.
  • the pin 7 is under an effect of a returning spring 6 by means of the transversal tip 5.
  • a bar shifting blocking device has a limiter 8 moved by the pin 7 and a spring 10 in a fixed bush 9 and coupled to a moving plate 11 of the electromechanical catch by a chain 13, a second plate 12 of the catch is fixed in a lock body 14.
  • the catch plates 11, 12 are divided by a thin dielectric clearance, and in the simplest case the surfaces of that both plates 11, 12, turned one to the other, are produced with a high polishing degree and have a conductivity. From the electrical point of view the catch is equivalent to a capacitor: once a voltage is applied on its plates they are charging by opposite polar charges. As known from the background art and particularly from the above mentioned references, the electrostatic attraction arises between the charged plates 11, 12 leading, under some condition, to a considerable mutual adhesion of these plates 11, 12, that is so called electroadhesive interaction . In a shown schematic structure these catch plates 11, 12 are able to move mutually and their mutual location may be fixed at an arbitrary moment due to the electroadhesion, by applying an electrical charge to these plates 11, 12.
  • Fig. 1 shows a starting state of the electronic lock mechanism.
  • the bar 1 is slid out of the body 14 (the state of "lock is closed"), the limiter 8 of the blocking device is lowered into the vertical hole of the bolt 2 by the spring 10 thus blocking a shift of the bar 1.
  • Fig.2 illustrates "cocking" of the blocking device.
  • the control lever 3 When the control lever 3 is turned clockwise, its left cam forces the tip 5 and raises the pin 7 which in its turn raises the limiter 8. In the final position shown in the Fig.2 the pin 7 comes into the fixed bush 9 thus operating as a limiter.
  • the moving plate 11 of the electromechanical catch shifts away from its starting position with regard to the fixed plate 12.
  • control lever 3 After the control lever 3 is turned counter-clockwise to its starting position there are two possible versions of the whole mechanism to operate.
  • the first version "idling" takes place when the catch plates 11, 12 are not supplied by the voltage. In this case an interaction between these plates is absent, and they are free in their mutual movement.
  • the spring 10 lowers the limiter 8 after the pin 7 is lowered to its starting position (Fig.1).
  • the second version "deblocking the lock" takes place when the catch plates 11, 12 are supplied by the voltage big enough for such an electroadhesive coupling of plates 11, 12 that counteracts a force of the tensed spring 10 and thus keeps the limiter 8 in a "cocked” state.
  • the pin 7 is being hid by its returning spring 6 into the vertical hole of the bolt 2 enabling it to shift longitudinally.
  • Fig.3 shows the final state of the lock mechanism.
  • the bar 1 is drew into the lock body 14 (the state of "lock is open”).
  • the longitudinal shift of the bar bolt 2 is performed by the peg 4 of the control lever 3 acting onto the vertical slot of the bolt 2 .
  • this invention may be used as the electromechanical blocking mechanism in automatic systems and particularly for its proper purpose, i.e. as an electronic lock for doors of premises, safes, vehicles, etc.
  • a simple design of the discussed electronic lock allows to produce it in a large-scale production.
  • a use of the electroadhesive effect based on electrostatic interaction of mechanism elements for blocking the mechanisms requires much smaller power consumption unlike of the use of the electrodynamic interaction in known blocking mechanisms having electromagnetic coils.
  • this invention allows to use the piezoelectricity (and the triboelectricity, or other types and methods of a quasistatic charge accumulation) to supply electronic locks having electroadhesive blocking devices.
  • the described lock elements the bar, the bar shifting mechanism, methods for mechanical blocking of the bar shifting mechanism by means of the limiter, the form and the constructions of electroadhesive catch elements etc., may differ.
