Description

DEVICE WITH FIRST AND SECOND LOCKING PINS AND METHOD

The present invention relates to a lock device, and in particular to a lock device for locking a door to a confined space to be used by different parties for goods handling. For instance, the confined space may be a confined space accessible from an external or outdoor location via said door. Then, the confined space may be used for the safe delivery of goods, and the storage of such delivered goods until collected. In general, the lock device is for locking such a door. The invention also relates to a method for operating such a lock device.

When delivering goods there is in general a problem of finding a point in time for the delivery when a party to receive the goods is available to receive the goods. In particular, it has proven difficult to find an efficient procedure for delivering goods the so-called "last mile", to the final address of an ordering user.

To solve this problem, it has been proposed to use a lockable delivery box, which can be unlocked both by the delivering party and the receiving user. Such unlocking may, for instance, be accomplished using a shared set of keys or using electronic locks.

However, shared keys are expensive to administer, not least when a key is lost and the lock (including all keys) must be replaced. Electronic locks are prone to malfunction, for instance due to battery failure. Hence, there is a need for an inexpensive locking mechanism not requiring a shared set of physical keys, but still allowing a receiving user to unlock the delivery box manually, without having to rely on an electronic lock functioning properly.

Such a box should still not be easily manipulated, and in particular the lock should not be easy to pick. The prior art comprises locks, such as the one described in GB2334546, that operate using a principle in which a cylindrical structure is rotated, such as using a key, in order to operate a locking mechanism from both sides of the lock. The prior art further comprises lock mechanisms as described in US6412318, US5018375, US8051689 and US5782118.

The present invention solves the above described problems. Hence, the invention relates to a lock device having an axial direction, a radial direction and an angular direction, which lock device comprises a lock cylinder, arranged to rotate angularly between a locked cylinder state and an unlocked cylinder state, which lock cylinder comprises a radially extending, open cavity; a first radially movable locking pin arranged to move in said cavity between a first radial position and a second radial posi- tion; and a key plug, mechanically connected to the first locking pin and activatable for moving the first locking pin between said first and second radial positions, which lock device is characterised in that the lock device further comprises a second locking pin, which second locking pin is radially movable between a locked pin state, in which the second locking pin protrudes radially into the elongated cavity when the lock cylinder is in said locked cylinder state thereby preventing the lock cylinder to rotate to said unlocked cylinder state, and an unlocked pin state, in which the second locking pin is arranged completely outside of said elongated cavity so that the lock cylinder can rotate to said unlocked cylinder state, in that the second locking pin is spring-loaded in an inwards radial direction towards the locked pin state of the second locking pin, and in that, when the key plug is activated for moving the first locking pin from the first to the second radial posi tion, the first locking pin is arranged to as a result, against a spring force achieving said spring-loading, push the second locking pin into the unlocked pin state.

The invention also relates to a method for operating a lock device, which method is characterised in that the method comprises the following steps: a) providing a container a door of which can be locked using a lock device of said type; b) either activating a pin movement limiting means, which pin movement limiting means is arranged inside said container, or remotely activating a remote control unit of said lock device so as to achieve an unlocked cylinder state of said lock device, in turn making it possible to open said door; c) opening said door; d) providing an article inside said container; e) if said pin movement limiting means is activated, inactivate said pin movement limiting means; f) closing said door; and g) activating the lock device so as to achieve a locked cylinder state of said lock device, in turn preventing the door from being opened.

In the following, the invention will be described in detail, with reference to exemplifying embodiments of the invention and to the enclosed drawings, wherein:

Figure 9 is a flow chart of a method according to the present invention.

Figures 1-8 share reference numerals for same or corresponding parts. Hence, Figure 1 illustrates a closable and lockable door 210 for a container 200 (Figure 8). The door 210 is arranged with a through hole 211 through which a lock device may be inserted for providing such lockability of the container 200 door 210. The locking function is provided by a radially R protruding latch 150, which may be conventional as such and which may for instance be of the type rotating into and out from a locked state of said latch 150. In Figure 1, a locked latch 150 state is illustrated.

Hence, the latch 150 is a rotary latch. It is, however, realized that the latch 150 may also be a linearly working latch, such as a sliding latch.

In the following, such a door 210 will be used to illustrate the functioning principles of a lock device 100 according to the invention.

Namely, Figures 2-5 illustrate a lock device 100 in four different states. The views of the lock device 100 in Figures 2-5 are simplified and not drawn to scale. However, it is realized that such a lock device 100 is generally arranged for being inserted through the hole 211 and for being mounted, such as by screwing, on an inside of said door 210.

The lock device 100 is associated with an axial direction A, a radial direction R and an angular direction V. The lock device 100 comprises a lock cylinder 110, which lock cylinder 110 may comprise a wing knob or similar, and is arranged to rotate angularly V between a locked cylinder state and an unlocked cylinder state. The lock cylinder 110 may be mechanically connected to the said latch 150, whereby an angular V rotation of the lock cylinder 110 results in a corresponding angular V rotation of the latch 150 between a locked latch orientation (shown in Figure 2 and corresponding to said locked cylinder state) and an unlocked latch orientation (shown in Figure 4 and corresponding to said unlocked cylinder state).

Generally, the lock cylinder is rotationally mounted in the door 210, such as via a rotary engagement with a lock part 212 (Figure 1) in turn fixedly mounted to the door 210. The lock cylinder 110 in turn comprises a radially extending, open cavity 111 (sprint hole), which is at least open in one end (the lower end in Figures 2-5, and through which open end an end of the second locking pin 140 is arranged to pass, see below) but which may also be open in both ends and then forming a through hole through the lock cylinder. It is noted that the cavity 111 has a generally radial extension, and may cross a centre of angular V rotation of the lock cylinder 110, but that it may alternatively be slightly radially offset in a direction perpendicular to a direction of extension of the cavity 111. It is partic ularly noted that the open cavity 111 rotates together with the lock cylinder 110. The cavity 111 may preferably be cylindrical, such as with a circular or oval cylinder cross- section.

The lock device 100 further comprises a first translationally and radially movable locking pin 120, in turn arranged to move in and along said cavity 111, along said direction of extension of the cavity 111, between a first radial position (illustrated in Figures 2 and 5) and a second radial position (illustrated in Figures 3 and 4).

Also, the lock device 100 comprises a key plug 130, in turn being mechanically connected to the first locking pin 120 and activatable for moving the first locking pin 120 between said first and second radial positions. This activation may take place in any way, but is preferably a direct mechanical activation mediated via said mechanical connection be tween the two. In Figures 2-5, the activation is achieved using an eccentrically (in relation to the centre axis of rotation of the lock device 100) mounted pin 112 (key plug follower) arranged to engage with a corresponding track in the first locking pin 120 and as a result move the locking pin 120 upwards/downwards in Figures 2-5 as the key plug 130 rotates angularly V in relation to (inside) the lock cylinder 110.

According to the invention, the lock device 100 further comprises a second locking pin 140 (spring bolt), which second locking pin 140 is translationally movable in a generally radial R direction, which generally radial R direction may be parallel to, or even the same as, said direction of extension of the cavity 111. Hence, the first pin 120 and the second pin 140 may be arranged to move in parallel to each other, or even along the same line. When the second locking pin 140 moves in said generally radial R direction, this move ment is between a locked pin state (illustrated in Figures 2) and an unlocked pin state (illustrated in Figures 3, 4 and 5). In the locked pin state, the second locking pin 140 protrudes in said generally radial direction into the elongated cavity 111. In this locked pin state, the lock cylinder 110 is furthermore in the above described locked cylinder state. In this state, the lock cylinder 110 is prevented from rotating to said unlocked cylinder state by said second locking pin 140. Namely, the second locking pin 140, which in the said locked pin state extends along a part of its length inside said channel 111, also extends outside of the channel 111 along a different part of its length. Hence, the lock cylinder 110 cannot rotate without offsetting the second locking pin 140 in the angular direction V, perpendicularly to tis generally radial direction R direction of extension, or rotating the second locking pin 140. Preferably, the second locking pin 140 may engage with a second locking pin 140 con finement structure (not shown), such as a cylindrical cavity, allowing said generally radial R movement but not allowing such angular V movement so as to achieve said rotary locking of the lock cylinder 110 in relation to the door 210. In said unlocked pin state, the second locking pin 140 is arranged completely outside of said elongated cavity 111 so that the lock cylinder 110 can rotate to said unlocked cylinder state (by it not being prevented form such rotation due to the second locking pin 140 not engaging with the lock cylinder 110). Further according to the present invention, the second locking pin 140 is spring-loaded in an inwards radial direction R towards said locked pin state of the second locking pin 140. In the Figures, this spring-loading is achieved using a metal spiral spring 141 forcing the second locking pin 140 upwards in Figures 2-5, but it is realized that any type of force applying means can be used, such as a gas spring, a plate spring or even an electromag- netically operating pushing means. When the key plug 130 is activated as described above, for moving the first locking pin 120 from the first to the second radial position, the first locking pin 120 is arranged to as a result, against a spring force achieving said spring-loading, push the second locking pin 140 into the unlocked pin state. This transition is illustrated in Figures 2 (where the key plug 130 is not activate) and 3 (in which the key plug is activated).

As is illustrated in Figure 3, when the key plug 130 is activated a distant (downward in Figure 3) end surface of the first locking pin 120 is flush with, or even slightly protruding from, a corresponding end of the elongated cavity 111. This achieves that the second locking pin 140 is effectively pushed completely out of the cavity 111, avoiding interfer ence between the second locking pin 140 and the cavity 111, while at the same time allowing the lock cylinder 110 to rotate in a housing without getting jammed due to the first locking pin 120 protruding out from the cavity 111. It is particularly noted that the first locking pin 120 at no point in time or space protrudes outside of the cavity 111 in a way resulting in that a rotation of the lock cylinder 110 is prevented. This is in contrast to many conventional lock devices, wherein such a corre sponding first locking pin is operated for locking the rotation of such a lock cylinder. Instead, in a lock device 100 according to the invention, it is the second locking pin 140 that locks the rotation of the lock cylinder 110, possibly (but not exclusively) as a result of an operation of the first locking pin 120, being withdrawn into the cavity 111 thereby making space of the second locking pin 140 to partly extend into the cavity 111. This provides a number of advantages, as will be apparent from the rest of this description. Hence, the door 210 may be opened by turning the lock cylinder 110 of the lock device 100. Such turning is only possible in case the second locking pin 140 is in said unlocked pin state. Such an unlocked pin state may be achieved by turning the key plug 130.

As mentioned above, the lock cylinder 110 may be connected to a radially protruding latch or cam 150, in turn arranged to rotate with the lock cylinder 110. In the lock device 100 illustrated in the Figures, the key plug 130 comprises a key slot 131 arranged to receive a key 132. Then, the lock device 100 may be arranged so that the key plug 130 can only be activated if a proper key 132 is inserted into the key slot 131. It is noted that the key plug 130 is activated in the said sense by rotation in relation to the lock cylinder 110, and it is then this rotation which may be blocked in case the correct key 132 is not used. Such blocking may take place in any conventional and suitable manner, such as using conventional lock pins cooperating with a corresponding key shape.

In Figures 2-5, the said distant end surface of the first locking pin 120 is entirely enclosed by the elongated cavity 111 throughout the possible movement interval of the first locking pin 120 between the first radial position and the second radial position.

Preferably, the first pin 120 is entirely enclosed in the elongated cavity 111. Hence, in an axial A projection, the first locking pin 120 may be entirely enclosed by a cylindrical envelope surface of the lock cylinder 110 at all times when the first locking pin 120 moves from the first radial position to the second radial position.

In the exemplifying embodiments of the present invention illustrated in the Figures, the lock device 100 furthermore comprises a pulling device 142, arranged to be activated to displace the second locking pin 140, in said generally radial R direction and against the above discussed spring force, to said unlocked pin state. In other words, the activation of the pulling device 142 results in that the pulling device 142 pulls the second locking pin 140 away from the cavity 111, out from the cavity 111 if the second locking pin 140 is already arranged partially within the cavity 111, up to said unlocked pin state of the second locking pin 140.

In particular, the pulling device 142 may be arranged to impart a radially R acting pulling force, resulting in a radial R movement, to the second locking pin 140. This force may be imparted using a manually operated mechanism, but is preferably imparted using an electromechanically operating pulling means, such as an electric motor. In Figures 2-5, the pulling device 142 is illustrated as a linear electric motor, but it is realized that any suitable mechanism may be used.

The pulling device 142 may be arranged to be activated in said manner by a control unit 160, which in turn may be an electronic control unit such as a microcomputer or similar.

Hence, the control unit 160 is arranged to emit electric control signals, such as a motor voltage, to activate the pulling means 142 to pull the second locking pin 140 out of en gagement with the cavity 111 and hence unlocking the lock device 100 so that the door 210 may be opened by rotating the lock cylinder 110 into its unlocked state and thereafter pulling the door 210 open.

The control unit 160, including any electric motors and other active parts, is preferably powered by a battery arranged inside the container 200, such as in the box 220 (see below).

This unlocked cylinder state is illustrated in Figure 4, wherein the latch 150 has swung out of engagement with the container 200 door 210, making it possible to open said door 210.

It is noted that either the key 132 or the pulling device 142 may be used/activated to achieve the unlocked pin state of the second locking pin 140. In other words, the lock device 100 can be unlocked either by using the key 132 or by activating the pulling device

142.

Figure 6 illustrates the case in which the first pin 120 is in said first radial position, since the key plug 130 has not been activated to propel the first pin 120 into its second radial position. Nevertheless, the second pin 140 is in the unlocked pin state, there being a play 112 in the form of an intermediary space between the first pin 120 and the second pin 140. In this state, the door 210 can be opened irrespectively of the rotary position of the key plug 130. This unlocked pin state can be achieved by a second pin movement limiting means 144 (see below), but it may also be achieved by activation of the pulling device 142 as de scribed above. Hence, the control means 160 can open the lock device 100 independently of if the key plug 130 is activated/rotated or not.

Preferably, the control device 160 as well as the pulling device 142 and the limiting means 144 are arranged inside the container 200, such as inside a lock box 220 fastened to the inside of the door 210. As is illustrated in Figures 2-6, the control unit 160 may comprise a remote control means or receiver 161, in turn arranged to receive a remotely originating control signal S and to, as a result of such reception of said signal S, automatically (under control of control unit 160) activate said pulling device 142 so that the door 210 can be opened. The remotely originating control signal S may be an electric signal, such as arriving into the lock box 220 from a remote location, for instance via a wired internet connection; a wireless electromagnetic signal, such as a Bluetooth^®, NFC, Zigbee^®, RFID radio or WiFi signal originating from a portable, digital wireless device such as a mobile phone or some other wireless token; a sound signal, such as a voice command spoken by a user; or a mechanical vibration signal, such as mechanical vibrations being imparted by a user knocking on the container 200 lock 210. In either case, such a signal is then detected and interpreted by the remote control means 160.

Furthermore, it is possible for the control device 160 to combine several such received and interpreted signals, and to only activate the pulling device 142 in case a predeter mined pattern of such signals, having predetermined characteristics, is detected. For instance, a wired or wireless electromagnetic signal can be combined with a mechanical signal to form such a pattern. In one example, the presence of a particular previously identified and associated (registered) mobile device can be detected using a wireless electromagnet signal, such as an RFID or Bluetooth^® signal. Then, once such presence has been detected, a mechanical signal, such as a detected vibration (of a predetermined minimum amplitude) due to a knock on the container 200 door 210, may cause the control means 160 to activate the pulling device 142.

As mentioned above, the lock device 100 may further comprise a pin movement limiting means 144, arranged to, when activated, lock the second pin means 140 in the unlocked pin state. For instance, the means 144 may be in the form of a simple sliding part, that can be manually activated to slide into a position (illustrated in Figure 5) in relation to a feature (such as a flange) 143 of the second pin 140, in which the movement of the second pin 140 is limited in a direction towards the cavity 111. Using the limiting means 144, the lock device 100 can be manually put in an unlocked state which is maintained as long as the limiting means 144 is active, irrespectively of the current state of the key plug 130 and the pulling device 140.

Figure 8 illustrates a container 200 comprising a main container body 201 and a container door 210. The container 200 further comprises a lock device 100 of the above discussed type, which lock device 100 is arranged to, when the lock device 100 is in said locked cylinder state, prevent the container door 210 from opening, and, when in said unlocked cylinder state, allow the container door 210 to be opened. From the exterior of the container 200 with its door 210 closed, only the key plug 130 and the lock cylinder 110 are visible, since the remaining components of the lock device are arranged inside the con tainer 200, such as in a lock box 220 fastened to the inside of the door 210.

A lock device 100 according to the above, and in particular when mounted for locking a container 200 as described herein, is useful for handling article logistics between different users. This will be exemplified in the following.

Namely, Figure 9 is a flow chart illustrating such a method using a lock device 100 and a container of the above described types. In a first step, the method starts. In a subsequent step, the container 200 is provided, comprising said door 210 as a door of the container which can be locked using a lock device 100 of the present type and as described above. In a subsequent step, the pin movement limiting means 144 is activated by a first user, which first user may be an owner of the container 200 or of a property on which the container is installed, and/or be a receiver of a handled article. As described above, the pin movement limiting means 144 is arranged inside the container 200. Due to this activa tion, the lock device 100 is put into an unlocked state irrespectively of a position of the key and also irrespectively of the pulling device 142. This activation may, for instance, take place by said user opening the door 210, activating the limiting means 144 and reclosing the door 210.

Alternatively, the remote control unit 160 of the lock device 100 may be remotely activat- ed, via a signal S. This may also be performed by the said first user, for instance by knock ing on the door 210 while carrying a previously associated RFID sender or Bluetooth^® enabled device held within range of the receiver 161. It may also be performed by a second user, which may be a delivering user having the task to deliver a particular article to the container 200 for subsequent collection by the first user. This second user may hence have her own wireless Bluetooth^® or RFID activate device, or have the capability of activating the receiver 161 in any other suitable manner, as has been exemplified above. Such an unlocking of the second user may take place in direct connection to delivery of an article to the container 200. Hence, at this point in the method an unlocked cylinder state of the lock device 100 has been achieved, in turn making it possible to open said door 210.

In a subsequent step, the door 210 is opened, such as by the second user. In a subsequent step, the article in question is provided, by the second user, inside the container 200. If, at this point, the pin movement limiting means 144 is activated, the pin movement limiting means 144 is inactivated in a subsequent step. In a further subsequent step, the door 210 is closed.

In a subsequent step, the lock device 100 is activated so as to achieve a locked cylinder state of the lock device 100, in turn preventing the door 210 from being opened. This activation may comprise remotely activating said remote control unit 160, in the way described above, so as to achieve said locked cylinder state. For instance, by knocking on the door 210 while having a pre-associated Bluetooth^® enabled smartphone, or an identi fied RFID tag, within range from the receiver 161, the second user may activate the control unit 160 so as to lock the lock device 100. Alternatively, after the door 210 has been closed, by turning the lock cylinder 110 until the cavity 111 is aligned with the second locking pin 140, the lock device 100 may snap into a locked cylinder state automatically, by the second locking pin 140 popping into the cavity due to said spring-loading of the second locking pin 140. The lock device 100 may even be designed so that this happens automatically as a result of the door 210 being closed, using a lock cylinder 110 aligning device (not shown in the Figures), automatically orienting the lock cylinder 110 so that the cavity 111 is aligned with the second locking pin 140 as the door 210 closes. This automatic locking upon closing may be available only when the key plug 130 is in a position in which the first locking pin 120 is in the first radial position (upper position as shown in Figures 2 and 5).

Hence, the second user can then leave, and the article is safely locked into the container 200 for later pickup by the first user.

At a subsequent step, the first user arrives at the container 200, and causes the control unit 160 to activate the lock device 100 (such as by knocking on the door 210 while having the mobile phone within range) to assume its unlocked pin state and hence make it possible to open the door 210 by turning the lock cylinder 110 to the unlocked cylinder state.

Alternatively, the first user may simply use her key to set the lock device 100 into said unlocked pin state, by inserting and turning the key 132 as described above. In other words, the user in this case inserts the key 132 into the key slot 131 of the lock device 100, activating the key plug 130 to achieve an unlocked pin state of the lock device 100, and then rotating the lock cylinder 110 into said unlocked cylinder state. In a subsequent step, the door 210 is opened.

In a subsequent step, the article is removed from the container 200, through the door 210. In a subsequent step, the method ends.

As can been seen from the above, the lock solution presently proposed can to be used as a digital lock, that is easy to assemble and install on both new and old boxes/storage solu tions. Digital keys (such as a cryptographic private PKI (Public Key Infrastructure) key stored in a smartphone), Bluetooth^® paring, or any other suitable digital wireless identifi cation method can be used for smartphone unlocking and sharing of access for permanent or one time access, typically for delivery drop-off purposes. The wireless device (smartphone, RFID tag, etc.) is hence used as a something-you-have authentication factor, corresponding to a physical key.

The "knock" sensing function (mechanical vibration signal detection) enables the lock to open in a very simple manner as long as a relevant wireless "key" is nearby. This way, the wireless access control mechanism can be run in the background, enabling opening without actively using the smartphone. As has been described above, the lock device 100 may also be opened by simply turning the key, as a backup or convenience.

Above, preferred embodiments have been described. However, it is apparent to the skilled person that many modifications can be made to the disclosed embodiments without departing from the basic idea of the invention.

For instance, the container 200 described herein may be used in many other circumstanc es, with or without additional features. For instance, it may be used as a letter box, having a conventional inlet slit opening for letters and being easily opened (using the door 210) both by a proprietor and mailmen delivering parcels that do not fit in the inlet opening for letters.

The pin limiting means may be used to leave the container in a permanently unlocked state, with the option of temporarily locking the container 200 in case valuable articles are to be placed therein.

The present invention may also be implemented in the form of a locking system, compris ing the lock device 100 but also a smartphone software function, executable on or from a general-purpose programmable digital portable device (such as said smartphone) and, when so executing, being capable of communicating with the remote sensor 161 to activate the control unit 160 in a secure manner, for instance by using conventional PKI cryptographic authentication. Such a software function may be arranged to present a GUI (Graphical User Interface) to a user of the smartphone, providing functionality for locking and unlocking the associated/paired lock device 100 remotely, by sending corresponding digitally coded wireless signal messages to the control unit 160 via receiver 161.

In general, everything which has been said herein in relation to the lock device and the container is equally applicable to the method, and vice versa. Hence, the invention is not limited to the described embodiments, but can be varied within the scope of the enclosed claims.
