Definitions

  • the invention relates to a lock accessory, whereby a key-operated lock is convertible into an electrically operated lock, the lock comprising a rotatable opening spindle and a turn spindle rotatable with a handle element, the accessory comprising a housing mountable on the surface of a door, into which said spindles extend and which contains a mechanism interconnecting the spindles, and said opening spindle being settable by an electric control through the mechanism in a drive link engagement with the turn spindle rotatable by means of the handle element, such that a rotation of the opening spindle translates into a rotational motion of the turn spindle as well.
  • a lock accessory of the above mentioned type is known from the patent publication SE 529017 C2 .
  • the lever mechanism of this SE publication is only apt for use in a type of locks which are provided with a lever or handle external of the door, thus requiring merely a drive link engagement between a spindle of the door lever or handle and a spindle of the door knob.
  • Such a drive link engagement is implemented in the cited SE publication by means of a solenoid-controlled lever mechanism.
  • These prior known electric locks include solenoid-driven levers, bringing the lock to an opening position as the solenoid receives a current.
  • the solenoid's power consumption is of such a magnitude that the excessively frequent need of replacing the batteries makes this accessory impractical.
  • An object of the invention is to solve the problem of how to conveniently convert a key-operated lock, into an electrically operated lock.
  • An additional object of the invention is to provide a battery-operated lock accessory, whereby a key-operated lock is convertible readily and at low cost into an electrically operated lock, whose energy consumption is extremely slight.
  • the lock in which the invention is applied, includes a turn spindle 3 rotatable with a handle element such as a door knob 3a, the door knob being set inside a door 1.
  • a key cylinder 2 Outside the door 1 is a key cylinder 2, which is normally used for opening the door 1 with a key.
  • the key cylinder is circular in cross-section.
  • the accessory of the invention comprises an opening ring, represented by reference numeral 5.
  • the opening ring 5 is preferably an annular element, comprising a circular wall which can be placed around the key cylinder 2.
  • the opening ring 5 is adapted to be rotatable around the key cylinder 2.
  • the circular wall has its inner surface provided with an internal serration 5a.
  • the opening ring 5 is preferably locked immovably in the direction of its rotation axis by means of a ring lock 7.
  • the ring lock 7 prevents movement of the opening ring 5 and its disengagement from around the key cylinder 2.
  • an annular void space Between an outer surface of the key cylinder 2 and the internal serration 5a is left an annular void space. Into the space, especially into a section above the key cylinder, has been passed a first end 4a of an elongated opening spindle 4. It should be noted here that a second end 4c of the opening spindle 4 is adapted to extend into the interior of a housing 6 mounted inside the door. The opening spindle 4 is adapted to spin around its longitudinal axis A as described hereinafter.
  • the opening spindle 4 has its first end 4a provided with a gear 4b, spinning jointly with the spindle 4 around the axis A of the spindle 4.
  • the gear 4b is meshed with the serration 5a of the opening ring 5, such that, as the opening ring is turned, the opening spindle 4 rotates around its axis A.
  • the opening spindle 4 has its second end 4c in engagement with a mechanism 40, 41, disposed inside the housing 6 and interlinking the spindles 3 and 4. Next described is one preferred configuration of the mechanism 40, 41.
  • the mechanism 40, 41 is accommodated in the housing 6 which consists of a bottom plate 6a and a cover element 6b, which latter can be fixed to the bottom plate 6a preferably in a removable fashion.
  • the housing 6 has its walls defining a space, into which the second end 4c of the opening spindle 4 extends at a distance above the turn spindle 3, which can be rotated by the door knob 3a or a lever shaped doorhandle.
  • the coupling element is a planetary gearset.
  • the planetary gearset 40 is made up of gears 40a, 40d and 40e.
  • the gear 40d is adapted to spin with the second end 4c of the opening spindle 4 around the axis A, and constitutes a so-called sun gear.
  • a second gear 40a Adapted to be rotatable around the axis A is a second gear 40a, which is larger in diameter than the gear 40d and constitutes a so-called ring gear.
  • the ring gear 40a lies on the same plane as the sun gear 40d. Consequently, the sun gear 40d is left within a space defined by an inner wall 40b of the ring constituting the second gear, i.e. the ring gear 40a.
  • the ring gear 40a comprises a planet flange 40c, providing a wall for the gear 40a.
  • the wall 40c is located adjacent to the bottom plate 6a of the housing 6, in its immediate proximity.
  • an annular space Between the inner surface 40b of the ring gear 40a and the plane extending by the outer serration crests of the sun gear 40d is left an annular space, in which is disposed a planetary gearset.
  • the planetary gearset consists of three gears 40e, whose rotating axles are set in connection with the planet flange 40c codirectionally with the rotation axis A of the sun gear 40d.
  • these rotating axles are spinning (as the planet flange 40c is rotating) around the axis A along a circular orbit and are disposed around the axis A at equidistant circumferential intervals (the radial distance is 120 degrees).
  • the planet gears 40e have their serrations meshed with those of the sun gear 40d.
  • the transmission element 41 is provided with a gear 41a, which is provided with an internal serration 41c and which can be passed to the engagement with the planetary gearset 40 in the direction indicated by an arrow B.
  • This gear 41a rotates around the same rotation axis A as the sun gear 40d and is bearing-mounted around the second end 4c of the opening spindle 4 for free rotation.
  • the transmission element 41 has its internal serration 41c meshed with those of the planet gears 40e.
  • the transmission element 41 comprises pulleys 41d and 41f adapted to be rotatable therewith.
  • the first pulley 41d co-rotates with the gear 41a, and the second pulley 41f rotates through the intermediary of a belt 41e as the first pulley 41d rotates.
  • the first pulley 41d is coupled to rotate by turning the opening ring 5 as discussed hereinbelow.
  • the second pulley 41f is disposed in the engagement with the turn spindle 3 (shown with dashed lines) of the door knob 3a, more specifically in such a way that the turn spindle 3 coincides with the rotation axis of the pulley 41f.
  • the engagement is such that, when the second pulley 41f rotates, the turn spindle 3 of the door knob 3a is also rotating, and so is thereby also the door knob 3a.
  • the turn spindle 3 has been passed through the pulley 41f, such that the turn spindle 3 and the pulley 41f have a common rotation axis.
  • the pulleys may be of equal or unequal in terms of their diameters, whereby the gear ratio of the pulleys 41d and 41f changes in compliance with the ratio of diameters according to per se known principles.
  • an actuator 10 operating on electric control.
  • the components essential for the operation of the actuator 10 are illustrated schematically in fig. 3 .
  • the actuator 10 After receiving an electrical control, the actuator 10 disables rotation of the ring gear 40a around the axis A.
  • the planetary gearset 40e is prevented from rotating around the axis A.
  • the actuator 10 receives a control command from the electronic circuit of a control unit 12, and the electric control from the control unit 12 to the actuator 10 is transmitted over a cable 13.
  • the actuator 10 includes a piezoelectric element 14 which, after receiving an electrical control, provides for the locking of a bolt or plunger 10a in the engagement with the serration of the ring gear 40e, thus disabling a rotational motion of the ring gear 40a.
  • the motion of the planet flange 40c, and that of the axles of the planetary gearset 40e connected therewith, around the rotation axis A is disabled.
  • the bolt or plunger 10a can be locked by means of the piezoelectric element 14 for opening the door.
  • a stopper means 15 of the piezoelectric element 14, for example a small tab 15, is passed by a small displacement into a detent 16 present in the bolt or plunger 10a in coincidence with the tab 15.
  • a spring 17 or some other power unit In connection with the bolt or plunger 10a is disposed a spring 17 or some other power unit, which allows, without electrical control, a displacement of the bolt or plunger 10a against the spring force while the bolt or plunger 10a is pressed back and forth against the spring force by the rotating ring gear 40a with its guide surfaces made up by serrations.
  • the planet gears 40e roll along the ring gear 41c, thus failing to transmit a torque for rotating the gear 41a.
  • said bolt or plunger 10a is adapted to disable or not to activate a coupling of the drive link engagement as the opening spindle 4 is rotated.
  • the sun gear 40d is rotated by a spinning motion of the opening spindle 4 around the axis A.
  • the planet gears 40e orbit around the axis A while rotating around their own rotation axes along the serration of the sun gear 40d.
  • the ring gear 40a is rotating around the axis A.
  • the transmission element 41a remains stationary, because the planet gears 40e have their pinions, which rotate freely on their axles, rolling freely along the internal serration 41c of the transmission element 41a, and the rotating force is not translated to the transmission element 41 but, by way of the planet flange 40c, to the ring gear 40a. Consequently, the door does not open as the opening ring 5 is turned from outside the door.
  • the ring gear 40a is locked in place (i.e. the ring gear 40a does not rotate around the axis A while the sun gear 40d is rotating). Because the planet gears 40e are provided on the planet flange 40c, the rotating axes of the planet gears 40a remain stationary, i.e. they do not orbit around the axis A, and the planet gears 40e rotate around their own axes. As a consequence, the force rotating the planetary gearset transmits to the first pulley 41d of the transmission element 41 through the intermediary of the internal serration 41c. Thereby, the transmission pulley 41d is rotating and so is also the second pulley 41f through the intermediary of the belt 41e. As a result, the turn spindle 3 of the door knob 3a turns and the door opens as the turn spindle 3 has turned to a sufficient extent.
  • the planetary gearset 40 transmits a force from the opening spindle 4 to the turn spindle 3, but the gearset functions also as a transmission ratio variator between the spindles 3 and 4 as the planet gears 40e change the angular speed between the internal serrations of the sun gear 40d and the transmission element 41a and, thus, the first pulley 41d as well. Because the first pulley 41d and the second pulley 41f of the transmission element 41 can be implemented, if desired, to have such diameters that the transmission ratio changes in a per se known manner, the door-opening turning motion of the opening ring 5 can be made optimal in terms of its turning angle and/or turning force.
  • the ratio between the respective turning angles of the spindles 3 and 4 can be set at 1:1, whereby the opening spindle 4 is rotated, for opening the door, practically with the same force and over the same radial distance as those used for turning the door knob 3a from inside.
  • the respective ratio between turning angles can be 1:2, whereby the opening spindle 4 is turned, for opening the door, over a double radial distance but with a lesser force.
  • the piezoelectric actuator 10 has a working time which only enables opening of the lock with the opening ring 5 for just a specific time span, which has been set in the electric control unit 12.
  • This control unit 12 receives its operating power from a battery 11 and functions only when a server 18 of the service provider has delivered an access right message to a specified mobile communicator 19, which can carry a list of addresses for doors whose opening authorization can be requested therefrom.
  • the accessory's electric control unit 12, or the mobile communicator 19 controlling the same can be adapted to emit an audio signal as soon as the electric control has coupled a drive link between the spindles 3 and 4. At this point, the user knows that the lock is openable by turning the opening ring 5 associated with the opening spindle 4.
  • the accessory according to the invention is thus located inside a door, while the opening ring 5 associated with the opening spindle lies outside the door. This means that, in a locked condition of the lock, the opening ring 5, the opening spindle 4 and the ring gear 40a in engagement therewith conduct a dead travel (no transmission to the coupling element 41) unless the accessory's mechanical drive link engagement has been coupled by means of electrical control.
  • the accessory may also include a micro switch 8 capable of switching the accessory's electric control unit 12 to a standby mode as the bolt or plunger 10a travels back and forth in response to a rotational motion of the opening ring 5.
  • the arrangement provides a considerable saving for the battery 11 because the accessory can now be in a totally power non-consuming state except for when opening of the lock is desired. In this case, it is first necessary to perform an activation twirl with the opening ring 5 and only then to communicate a control message from the mobile communicator 19 to the control unit 12. This communication may function by using any short range communication link.
  • the accessory of the invention can be used, for instance, to change an ordinary Abloy lock into an electrically controlled lock. It is economical and quick to install and can be removed without leaving marks on the door.
  • the invention is not limited to the above exemplary embodiment, but a mechanical drive engagement can be implemented by a skilled artisan by using various combinations of pinions and transmission gears.
