Definitions

  • the present invention relates to a key box for safe handling of keys, and a method performed by the key box.
  • WO 04/018804 discloses a method and a device for safe handling of keys.
  • the device aiming at providing an electronic method for safe handling of a key, in which a casing is fixed to an object having an accessible side, a lockable body is arranged to be moveable between an open position and a closed and lockable position inside said casing, by an electrically/electronically controlled locking device, for safekeeping a key inside said casing such that said key is non-obtainable from the accessible side of the object when the lockable body is in its closed position but only obtainable from the accessible side of the object when said body is in the open position.
  • the lockable body is arranged to be displaccable inside said casing and the said locking device is placed to be inaccessible from the accessible side of the object, in one or more embodiments this is exemplified by the casing being a cylindrical insert attached to the object, and by the lockable body is a hollow cylinder in which the key may be positioned.
  • the device and method described above is functional, still there is room for improvement, particularly in terms of power consumption.
  • the present invention provides a key box eliminating the problems mentioned in relation to prior art.
  • the inventive key box is particularly well-suited for retrofit to a specific location, since the very low power consumption is ideal for a battery powered device. Further advantages will be described in the following detailed description of preferred embodiments.
  • the present invention provides an electronic device for safe handling of a key, adapted for arrangement at a structure with an accessible side and a side with limited access.
  • the device comprises a mounting clement mounted to the structure, in a direction from the accessible side towards the side with limited access, a lockable body insertable in the mounting element; a control unit; and a lock mechanism arranged on the side of the structure with limited access.
  • the lock mechanism operably cooperates with the lockable body via a lock element when the lockable body is inserted in the mounting element, said lock element being movable in a locking direction and an unlocking direction, wherein the control unit is adapted to control the lock mechanism to unlock the lockable body based on an external input.
  • the device comprises a motor having a rotatablc drive shaft, which is controlled using the control unit, for moving the lock element into, and out of, engagement with the lockable body.
  • the driveshaft is operatively coupled to the lock element via at least one eccentric cam element.
  • An eccentric cam element provides an efficient coupling in order to transform the rotational motion of the driveshaft to a lateral movement of the lock element. The frictional losses may be reduced as compared to a geared solution, yet the eccentric cam is reliable and rugged.
  • the cam element may further be in operative contact with the lock element in two contact positions, one in the opening direction and one in the closing direction.
  • the operative contact makes the control of the device direct and reliable. Further, the control may be performed with high precision.
  • the friction in a contact point between the cam element and the lock element in structurally reduced.
  • the structural reduction of friction may be performed in several ways, all with the main purpose of reducing the power consumption. Examples include natural low-friction materials, such as TPFE, in components abutting each other in the contact point; roll bearings, ball bearings etc arranged on one or both of the components being contacted.
  • the contact point provided in the locking direction may be provided on a spring-biased element, biasing the lock element in the locking direction.
  • the spring-biased element will, as evident, bias the lock element in the locking direction.
  • this also allows for a high-precision contact, at the same time as the lock element will be free to move by another cause than the rotation of the eccentric cam element. For example, this makes it possible for the lock clement to remain in the locked position when the lockable body is inserted. Further, it will be possible to manipulate the lock element manually from the side of the structure with restricted access, as will be discussed later on.
  • the spring-biased element may in one or more embodiments comprise a leaf spring, operatively attached to the lock element.
  • the leaf spring provides a rugged solution with few movable parts providing the desired biasing function. Since the spring is attached to the lock element it will move with the latter. This effectively means that during movement of the lock element the motor does not have to work against the resilient force of the spring, since it will follow the lock element automatically.
  • the frictional reduction may be performed by designing the cam element as a cam roll, comprising a roll or ball bearing decoupling the inner circumference of the cam element from the outer circumference. This construction is a simple and reliable way of reducing the friction.
  • two cam rolls may be arranged on the drive shaft; a first contacting the lock element in the opening direction, and a second contacting the lock element in the closing direction.
  • lock element In order to provide a direct and reliable lock element it may be formed in one piece by a stamped plate of sheet metal and wherein the portion of the lock element engaging a recess in the lockable body comprises an area being bent in a direction away from the accessible side of the structure. The bent portion cooperates with the lockable body, such that it would require a considerable effort to pry the lockable body open. Combined with that the lockable body is difficult to grasp with a tool from the outside this provides an efficient safeguard from unauthorized access
  • An inventive method for operating the device may comprise the steps of: - activating of the device authenticating the user by means of wireless communication with a user carried unit, such as a mobile phone operating the lock mechanism to assume an unlocked position and release the lockable body.
  • the activation step is generally necessary since the device may incorporate the feature of having a stand-by mode, in which it simply awaits a "wakc-up call", which could be effected by a knock on the structure in which the device is mounted.
  • the knock may be detected by a vibration sensor.
  • control unit determines that the unlocked position is reached by means of monitoring the current consumed by the motor, which is an efficient way of determining the position of the lock element.
  • the lock mechanism may be operated to assume the locked position based on the determination that the unlocked position has been reached or that the lockable body has been reinserted in the mounting element. In the presently most preferred embodiment the lock mechanism returns to the locked state after the unlocked position has been reached. Once the unlocked position is reached the lockable body will be ejected, and thanks to the spring-biased lock element it is possible to reinsert the lockable body without unlocking the lock element actively.

  • the key tube 2 has a tapered end portion 4 to facilitate insertion into the mounting tube 8 and the tapered end portion 4 terminates, at its portion remote from the end of the key tube 2, with a circumferential recess 6 in the form of a step towards the center of the key tube 2.
  • the recess 6 is adapted io cooperate with a lock slide, to be described.
  • the mounting tube 8 has an essentially cylindrical outer shape, which facilitates the arrangement of a hole in the structure through which the mounting tube 8 is to extend.
  • the inner through hole of the mounting tube 8 has a shape allowing the insertion of the key tube 2.
  • the flange After insertion of the mounting tube 8, the flange will abut the accessible side of the structure and the mounting tube 8 will be secured to the structure by means of nuts 12, 14 arranged on threads 16 on an outer periphery of the mounting tube 8, on the non-accessible side of the structure.
  • a mounting piece 15 is arranged between the structure and the nuts 12, 14, for facilitating the subsequent mounting of components.
  • a biasing spring 17 is arranged to bias the key tube 2 towards the accessible side of the structure, such that if the key tube 2 is released, it will be ejected in this direction.
  • the tapered end portion 4 projects, when inserted in the mounting tube 8, through the structure, and is fixed by an angled flange portion 18 of a lock element in the form of a lock slide 20.
  • the lock slide 20 is arranged to slide in a direction essentially perpendicular to the insertion direction (the length axis of the key tube 2 and the mounting tube 8), and is biased by a leaf spring 22 in a locking direction, towards a locking position in which the flange 18 of the lock slide 20 cooperates with the recess 6 of the key tube 2.
  • the lock slide 20 is a piece of profiled sheet metal, and the flange portion 18 is formed from the same piece of metal as the rest of the lock slide 20 and is bent in the insertion direction of the key tube 2 (away from the accessible side of the structure).
  • This particular shape makes it difficult to pry the key tube 2 open, since the actual key tube 2 will prevent the flange portion 18 from bending in an opening direction, which is described in more detail later, referring to Fig. 3.
  • the lock slide 20 has a hole 24, which will permit insertion of e.g. a screwdriver in order to allow for the lock to be opened from inside in case of power failure or other error.
  • the hole 24, or another mechanism coupled to the lock slide is used to pry the lock open the leaf spring 22 will bias the lock slide 20 back towards its original position.
  • the hole 24 could obviously be replaced by a more complex construction, e.g. a lever (not shown) with a release mechanism such that it does not induce any considerable friction during normal operation of the device.
  • a motor mount 26 and a motor 28 are mounted to the mounting piece 15.
  • the motor is an electrical DC motor, preferably a brushless motor.
  • the motor drive shaft 32 extends directly or indirectly via the guide pin 37, to a shaft support (not shown), which prevents it from bending or flexing under load.
  • the shaft support may be designed as an opening in the lock casing 39.
  • On the drive shaft 32 two cam rolls 34 and 36, respectively, are arranged.
  • the cam rolls 34 and 36 basically consist of cylindrical roll bearings arranged on a central cylindrical piece 35 with an offset through hole for the drive shaft 32.
  • the cam rolls 34, 36 will thus be eccentrically arranged on the shaft 32.
  • a guide pin 37 extends coaxially with the driveshaft 32, as apparent from Fig. 3.

  • the outer cam roll 36 abuts, with its roll bearing, the leaf spring 22 and the inner cam roll abuts, with its roll bearing, the lock slide 20. This arrangement greatly reduces frictional losses, since there will be no sliding movement between the roll bearings and corresponding abutment surface.
  • the leaf spring 22 is operably connected to the lock slide 20, in the slots illustrated in Fig. 1 , and serves two main purposes.
  • the second purpose is the hold the lock slide 20 in contact with the eccentric cam rolls 34, 36. If only the latter purpose was to be achieved, i.e. if the security function provided by the hole was solved by other means the leaf spring 22 could be removed, and replaced with an opening 27 fitting more tightly to the cam rolls 34, 36.
