Definitions

  • the invention relates to a lock system comprising a mechanical lock and in particular a mechanical lock that can be operated by means of electrical actuation.
  • US 4,800,741 discloses a lock system comprising - among others - a housing, a bolt displaceable in the housing, a strike which receives the bolt, a solenoid which is mounted on the housing and has a coil, a plunger which is axially reciprocal in the coil, a spring which is operatively braced between a crosspiece fin and the housing and an apparatus which electrically energises the coil.
  • the spring urges the bolt is urged in an outer position, so at least partially sticking outside the housing, for locking a door.
  • the bolt By energising the solenoid, the bolt is retracted to permit a door in which the lock system is placed to be opened.
  • the bolt can be held in retracted position if desired. This is done by leaving the solenoid energised, which means that the solenoid is constantly provided with a current. This results in heating up of the windings of the coil, which may finally result in damaging or even destruction of the coil.
  • the invention provides a lock system comprising a mechanical lock comprising: a lock casing comprising a first bolt being movable between an unlocked position in which the first bolt is fully comprised by the lock casing and a locked position in which the first bolt is partially located outside the casing; a first electromechanical actuator connected to the bolt, which first electromechanical actuator is arranged to move the first bolt from the unlocked position to the locked position in response to receiving an electrical pulse; and a second electromechanical actuator that in response to receiving an electrical pulse enables the first bolt to move from the locked position to the unlocked position.
  • a first advantage of this set up is that energy is only used to lock or unlock the lock, so less energy is used.
  • a second advantage is that the door can be kept unlocked for a longer amount of time, without heat dissipation building up in electromechanical actuators that may lead to damaging or destruction of the electromechanical actuators. In particular windings of solenoids are susceptible to this issue.
  • the lock system further comprises: a first biasing element for biasing the first bolt towards the unlocked position; and a bolt blocking member movable between a blocked position in which the blocking member is enabled to block the first bolt if the first bolt is in the locked position and an unblocked position in which the first bolt is not blocked by the bolt blocking member, wherein the second electromechanical actuator is connected to an actuating member arranged to engage with the bolt blocking member for moving the bolt blocking member from the blocked position to the unblocked position.
  • the first bolt may be automatically blocked after a movement to the locked position.
  • a first advantage is that this means that the bolt is well secured against tampering with the lock.
  • a second advantage is that by providing an electrical pulse to the first electromechanical actuator, the first bolt is moved to the locked position where it can be blocked. Upon blocking, the electrical pulse can be removed and the first bolt will remain in the locked position. Upon moving the blocking member to the unblocked position, the first bolt will move to the unlocked position by virtue of the first biasing element. So an electrical pulse provided to the second electromechanical actuator will result in the first bolt moving to the unlocked position.
  • the bolt is movable in a substantially linear way
  • the first electromechanical actuator mechanically actuates in a substantially linear way
  • the bolt and the first electromechanical actuator are coupled by means of a coupling member translating a movement of the electromechanical actuator in a movement of the bolt that is substantially perpendicular to the movement of the first electromechanical actuator.
  • the first electromechanical actuator is a solenoid comprising a first winding and a first movable armature arranged to move in a substantially linear way; and the second electromechanical actuator is a solenoid comprising a second winding and a second movable armature arranged to move in a substantially linear way.
  • Solenoids are well known and widely available actuators, making construction of the lock system convenient.
  • the bolt is moved to the locked position by the first movable armature moving into the first winding.
  • force built up in the biasing element may increase.
  • the force exerted by the first winding on the first movable armature is built up as well. This prevents issues in case the force exerted on the first movable armature would decrease during moving the first bolt to the locked position.
  • Yet another embodiment of the lock system according to the invention comprises a sensor for detecting whether the first bolt is in at least one pre-determined position.
  • This embodiment provides possibilities for controlling electrical pulses to the lock system in a controlled way.
  • feedback data is generated that may in turn be used to provide any electrical pulses for actuating the electromechanical actuators in an efficient way. Pulses for putting the first bolt to a pre-determined position need only to be provided until it has been detected that the first bolt is in that pre-determined position.
  • the invention provides a building locking system comprising: at least one lock system according to any of the preceding claims; and a lock control unit couplable to the lock system and enabled to actuate the electromechanical actuator of the lock system.
  • Figure 1 A discloses a first lock system 100 as an embodiment of the lock system according to the invention. Whereas practical embodiments of the lock system according to the invention will in most cases comprise more elements than disclosed in Figure 1 A, Figure 1A primarily discloses the lock system 100 comprising elements that are relevant for describing the invention and embodiments thereof. This applies to Figure 1 B as well, which discloses the lock system 100 in a closed or locked state, whereas Figure 1A discloses the lock system 100 in an opened or unlocked state.
  • the lock system 100 comprises a lock casing 110 comprising a bolt 112.
  • the bolt 112 is slidable between an unlocked position wherein the bolt 112 is located inside the lock casing 110 as shown by Figure 1A and a locked position wherein the bolt is partially located outside the lock casing 110 as shown by Figure 1B .
  • the lock system 100 further comprises a bolt spring 116 acting as a biasing element, a bolt blocking tumbler shaft 120, a blocking spring 128, a first solenoid 130 comprising a first plunger 134 and a first stationary part 132 comprising a first coil (not shown) in which the first plunger 134 fits and a bolt connecting element 136 connected to the first plunger 134.
  • the lock system 100 is preferably fit in a door, with the bolt 112 engaging with a hole in a doorpost for locking the door.
  • the door is locked with the bolt 112 is in the locked position and the door is unlocked with the bolt 112 in the unlocked position or in any case substantially comprised by the lock casing 110 that the bolt 112 is not in the hole of the doorpost anymore.
  • the blocking tumbler shaft 120 is slidable by virtue of an elongated opening 122 in the blocking tumbler shaft 120 in which a holding pin 124 fits, which holding pin 124 is connected to the lock casing 110.
  • the blocking tumbler shaft 120 is slidable between an unblocked position as shown in Figure 1A and a blocked position as shown in Figure 1B .
  • the blocking tumbler shaft 120 is biased towards the blocked position by means of the blocking spring 128 that is connected to the blocking tumbler shaft 120 via a blocking spring pin 126 protruding from the side of the blocking tumbler shaft 120.
  • the position of the bolt 112 can be controlled by means of a key, as will be discussed later in further detail.
  • a key By operating the key in a first direction, preferably by turning it clockwise, viewed from the drawing plane, the blocking tumbler shaft 120 can be slid towards the unblocked position and subsequently the bolt 112 can be slid back to the unlocked position by the same key operation.
  • the bolt 112 As the bolt 112 is biased towards the unlocked position by means of the bolt spring 116 acting on a bolt spring pin 114 protruding from the side of the bolt 112, sliding the bolt 112 to the unlocked position will be a relatively light operation.
  • the bolt 112 By operating the key in a second direction, opposite to the first direction, the bolt 112 can be slid from the unlocked position to the locked position. It is noted that this action involves loading the bolt spring 116. If the bolt 112 has been moved to the locked position, the blocking tumbler shaft 120 is slid towards the blocked position by virtue of the biasing force of the blocking spring 128, thus acting as a bolt blocking member that is blocking the bolt 112 from moving from the locked position to the unlocked position.
  • the lock system 100 may be closed by operating a key. Additionally or alternatively, the lock system 100 may be closed remotely by means of the first solenoid 130.
  • the first solenoid 130 By applying a current to the first coil comprised by the first stationary part 132 of the first solenoid 130, the first plunger 134 is expelled from the first stationary part 132 by virtue of an electromagnetic force. This results in pushing out the bolt 112 from the lock casing, via the connecting member 136.
  • the first plunger 134 may also be directly connected to the bolt 112. As the first coil may be energised remotely by providing an electrical current via wires, the lock system 100 may be closed remotely.
  • the bolt 112 After the bolt 112 has been pushed out, the bolt 112 is blocked by the blocking tumbler shaft 120 as discussed before. This means that the first coil of the first solenoid 130 only requires to be energised for a limited period. This period should be long enough to move the first plunger 134 so far out that the bolt 112 is expelled from the lock casing 110 and the blocking tumbler shaft 120 is pulled down by the blocking spring 128 to block the bolt 112 in its expelled or locked position. With the bolt 112 blocked by the blocking tumbler shaft 120, the bolt 112 cannot be retracted anymore by means of the bolt spring 116 and the first coil of the first solenoid 130 does not have to be energised anymore.
  • the lock system 100 is provided with a second solenoid 230 as depicted in Figure 2A en Figure 2B .
  • the first solenoid 130 ( Figure 1 ) has been omitted to enhance clarity of the figure, but the features additionally disclosed in Figure 2 can be combined with those of Figure 1 .
  • Figure 2 A shows the lock system 100 in the closed state, with the blocking tumbler shaft 120 blocking the bolt 112 thus holding the bolt 112 in the locked or expelled position.
  • the blocking tumbler shaft 120 is kept in place by the blocking spring 128.
  • the lock system 100 is complemented with a second solenoid 230 comprising a stationary part 232 comprising a second coil (not shown) in which a second plunger 234 is fit that is arranged to move linearly over the length of the second solenoid 230.
  • a lever 236 as an actuating member is provided that engages with the blocking tumbler shaft 120.
  • the second plunger 234 Upon energising the second coil of the second solenoid 230 by applying a current to the second coil, the second plunger 234 is pulled inside the second coil comprised by the second stationary part 232. With this movement, the lever 236 brings along the blocking tumbler shaft 120, moving the blocking tumbler shaft 120 from the blocked position to the unblocked position.
  • first plunger 134 and the second plunger 234 should be able to move freely within the first stationary part 132 and the second stationary part 232, respectively.
  • the friction between the plungers and the stationary parts should at least be lower than the forces exerted by the bolt spring 116 and the blocking spring 128.
  • FIG. 3 shows a lock system 300.
  • the lock system 300 comprises a lock casing 310 comprising a bolt 312 slidable between a locked position depicted by the dashed line and an unlocked position depicted by a solid line.
  • the bolt 312 is biased towards the locked position by a bolt spring 316 that acts on a bolt spring pin 314 that is connected to the bolt 312.
  • the lock system further comprises a blocking tumbler shaft 320 that is slidable from the unblocked position depicted in Figure 3 to a lower blocked position in which the blocking tumbler shaft 320 blocks the bolt 312 if the bolt 312 is in the locked position depicted by the dashed line.
  • the blocking tumbler shaft 320 is biased by a blocking spring 328 to the blocked position.
  • the blocking spring 328 interacts with the blocking tumbler shaft 320 at the top of the blocking tumbler shaft 320. If the bolt 312 has been moved to the locked position, the blocking tumbler shaft 320 will move to the blocked position by virtue of the biasing force of the blocking spring 328.
  • the bolt 312 is pivotally connected to a closing tumbler 374.
  • the bolt 312 can be moved to the locked position by moving the closing tumbler 374 to the left, viewed from the plane of Figure 3 .
  • the lock casing 310 comprises a lock cylinder opening 370 in which a lock cylinder 400 as depicted in Figure 4 may be fit.
  • the lock cylinder 400 comprises a cylinder housing 402, a key slit 408 and a cylinder cam 404 comprising a cylinder notch 406.
  • a key is stuck in the key slit 408. If the combination of the key fits the combination of the lock cylinder 400, the key can be turned, resulting in turning the cylinder cam 404 with the cylinder notch 406.
  • the cylinder notch 406 is able to interact with the closing tumbler 374, and a lower left part of the blocking tumbler shaft 320.
  • Turning the key of the lock cylinder 400 to the left (counter clockwise) will result in the cylinder notch 406 pushing the closing tumbler 374 to the left, resulting in the connected bolt 312 to be moved to the locked position.
  • the blocking tumbler shaft 320 moves to the blocked position by virtue of the force of the blocking spring 328 acting upon the blocking tumbler shaft 320.
  • the lock system 300 can also be remotely locked and unlocked by means of an electrical pulse.
  • a first solenoid 370 is provided.
  • the first solenoid 370 comprises a first stationary part 372 comprising a first coil (not shown) in which a first plunger 374 is fit.
  • the first plunger 374 is fit such that it is linearly movable.
  • the first plunger 374 is connected to a first connecting member 376, which connection is preferably pivotable.
  • the first connecting member 376 is connected to a tumbler wheel 380.
  • a second connecting member 378 is provided to connect the tumbler wheel 380 to the bolt 312.

  • the tumbler wheel 380 translates a linear movement of the first plunger 374 to a linear movement of the bolt 312 which movement of the bolt 312 is substantially perpendicular to the linear movement of the first plunger 374.
  • Connecting the bolt 312 to the first solenoid 370 via the tumbler wheel 380 has multiple advantages.
  • the arrangement shown on Figure 3 allows that the expelling of the bolt 312 is done by pulling the first plunger 374 in the first stationary part 372. So the more the bolt 312 is expelled, the more force is applied. This is advantageous, because while the bolt 312 is being expelled, the bolt spring 316 is loaded and the force built up increases. The latter means that the force to be provided to the bolt 312 to overcome the force applied by the bolt spring 316 to the bolt 312 has to increase as well.
  • the force of pushing out the first plunger 374 would decrease, with an increasing force required to load the bolt spring 316. If at a certain moment the force exerted on the first plunger 374 would be lower than the force built up in the bolt spring 316, the risk may occur that the bolt 312 would not be fully expelled.

  • the projection is provided such that the micro switch 390 is pushed when the bolt 312 is fully expelled so the lock system 300 is in the locked mode. This allows detection of full locking of the lock system 100, upon which energising the first coil of the first solenoid 370 can be stopped. In this way, an energising pulse provided to the first solenoid 370 can be kept as short as possible, thus saving energy.

  • the second coil of the second solenoid 330 attracts the second plunger 334, resulting in the lever 336 to move in an upward direction. If the blocking tumbler shaft 320 is in the blocked position, the tumbler shaft 320 is moved in the unblocked position, unblocking movement of the bolt 312. Subsequently, by virtue of the bolt spring 316, the bolt 312 slides to the unlocked position.
