Definitions

• the invention relates to a lock of a device cabinet, compartment box or other cabinet.
• Compartment boxes and cabinets are used for example in schools and locker rooms of work places and sports halls. Additionally, they are used for example in power plants and telecommunications networks for protecting machinery, i.e. in this case they are called device cabinets.
• a device cabinet lock in this context also means a lock of a compartment box or other cabinet.
• a device cabinet lock is equipped with a lock cylinder.
• the lock cylinder is turned open with a therein fitting key.
• the lock cylinder comprises an opening with a certain shape, wherein a key fits, which has corresponding shapes.
• the lock cylinder turns, whereby a latch or a latch controller attached to the rear end of the lock cylinder turns from the closed position to the open position and vice versa.
• the latch is in the open position, the lid of the device cabinet, compartment box or other cabinet can be turned open.
• the key can thus for example be a spindle shaped in a certain way, and the lock cylinder thus has corresponding shapes.
• the key is a so-called coded key, which has certain shapes, and the lock cylinder has tumblers for these shapes.
• the shapes of the key thus make up a certain code, with which the tumblers of the lock cylinder can be turned into a release position, and thus the lock cylinder can also be turned into the open position.
• the aim is to make the device cabinet locks as cost-efficiently as possible, whereby their structure is kept simple.
• a turning latch attached to the lock cylinder is usually used as a locking element.
• the safety level of the device cabinet locks is not necessary very good.
• the object of the invention is to provide a device cabinet lock, the safety level of which is better than in previous device cabinet locks.
• An additional object is that the increased safety level is achieved in a cost-efficient manner.
• the device cabinet lock 1 comprises a turning latch 2, which is connected to a turning axis 3.
• the latch and turning axis are arranged to turn from a locking position to an open position and vice versa.
• the turning axis 3 is connected to a lock cylinder ⁇ which is arranged to transferforce caused by the turning of a key to the turning axis 3 in order to turn it and the latch 2.
• the device cabinet lock 1 also comprises a deadlocking means 5, which is arranged to prevent the turning axis
• the deadlocking means 5 is arranged to turn from the deadlocking position into a release position and vice versa.
• the movement direction of the deadlocking means 5 from the deadlocking position to the release position is opposite compared to the movement direction of the latch 2 from the locking position to the open position.
• the device cabinet lock 1 comprises a control means 6A, 6B for the deadlocking means 5, to control the deadlocking means from the deadlocking position to the release position.

• Figure 7 shows an example of a device cabinet lock according to the invention with the deadlocking open by electronic control
• Figure 8 shows an example of the deadlocking locking means of a device cabinet lock according to the invention
• Figure 9 shows an example of a plate of the deadlocking means.
• Figure 1 shows an example of a device cabinet lock according to the invention.
• the device cabinet lock is installed inside the lid / door a device cabinet, a compartment box or other cabinet.
• the lid or door has holes for lock cylinders 4, 6A.
• Figure 1 thus shows the device cabinet lock from the side which is set against the inner surface of the lid / door of the device cabinet, compartment box or other cabinet.
• FIG 2 shows an example of the device cabinet lock as deadlocked.
• the device cabinet lock 1 comprises a turning latch 2, which is connected to a turning axis 3.
• the latch and turning axis are arranged to turn from a locking position to an open position and vice versa.
• the turning axis 3 is connected to a lock cylinder 4, which is arranged to transfer force caused by the turning of a key to the turning axis 3 in order to turn it and the latch 2.
• the lock cylinder is thus used with a therein fitting key, which is known as such.
• the lock cylinder can be made in different ways. In the example of Figure 2, the lock cylinder is short and does not necessarily comprise separate tumblers.
• the locking is based on the shapes of the key opening and cylinder of the lock cylinder and the corresponding shapes of the key.
• a turning axis 3 is connected to the lock cylinder, which turning axis can also be a fixed part of the lock cylinder. From Figure 2 can also be seen how the latch 2 can be attached to the turning axis 3. In this example there are two straight surfaces 3A of the turning axis, which relay turning force from the turning axis to the latch 2 via its counter surfaces.
• the device cabinet lock 1 also comprises a deadlocking means 5, which is arranged to prevent the turning axis 3 and latch 2 from being turned into the open position in the deadlocking position of the deadlocking means 5.
• the deadlocking means 5 is arranged to turn from the deadlocking position into a release position and vice versa.
• Figure 8 shows in more detail one embodiment of the deadlocking means.
• the movement direction of the deadlocking means 5 from the deadlocking position to the release position is opposite compared to the movement direction of the latch 2 from the locking position to the open position. Thus, it is very difficult or even impossible to manipulate open the device cabinet lock.
• the device cabinet lock 1 also comprises a control means 6A, 6B for the deadlocking means 5, to control the deadlocking means from the deadlocking position to the release position.
• FIG 8 shows one embodiment of the deadlocking means.
• the deadlocking means 5 comprises a plate 7.
• Figure 9 shows in more detail one embodiment of the plate.
• the deadlocking means can for example also be a cast piece, which has a central hole, and from which protrusions extend in different directions.
• the plate is connected in a turning manner to the turning axis 3, and the plate 7 has a control protrusion 7A, 7B for the control means 6A, 6B of the deadlocking means and a deadlocking surface 7C.
• the device cabinet lock additionally comprises a gearwheel 8, which is connected to the turning axis 3 and arranged to turn with the turning axis, and a gear rack 9, which has a counter locking surface 9A for the deadlocking surface 7C and an indentation 9B, which is in connection with the gearwheel 8.
• the gearwheel is only slightly visible behind the plate 7 in the Figure 8.
• the plate has a round installation hole 7E, whereby the plate 7 can turn in relation to the turning axis 3 regardless of the position of the turning axis.
• the figures of this presentation show an embodiment, the plate 7 of which has two control protrusions 7A, 7B, but it is possible to form an embodiment with only one control protrusion.
• the embodiment of the invention can for example be such that either of the protrusions of the plate 7 is missing.
• the embodiment in the figures uses two gear racks 9, 10, but it is possible to make an embodiment, which has only one gear rack.
• the plate 7 In the one gear rack embodiment, the plate 7 only needs to have one deadlocking surface 7C.
• the plate 7 can have two deadlocking surfaces 7C, 7D. The plate thus has at least one deadlocking surface.
• the gear teeth enter the gaps between the indentation 9B of the gear rack 9, whereby when turning the turning axis 3 (with a key via the lock cylinder), the gear rack strives to move in a linear manner. If the plate 7 or other embodiment of a deadlocking means is in the deadlocking position, its deadlocking surface 7C (or 7D) is against the counter locking surface 9A (or 10A) of the gear rack, whereby the linear movement of the gear rack and simultaneously also the turning of the turning axis 3 and latch 2 is prevented. The device cabinet lock is thus deadlocked. As was already stated, there can also be two gear racks in the device cabinet lock, whereby there can also be two deadlocking surfaces. Also the second rack 10 is connected to the gear wheel 8 via its indentation 10B.
• the gear racks there is double indentation in the gear racks, i.e. there is indentation on both edges of the rack, but one indentation is sufficient for providing the desired operation.
• a second gear wheel can also be arranged for the turning axis.
• the indentations can overlap each other, as is shown in the embodiment of the figures.
• the gear rack 9 (or 10) or gear racks 9, 10 do not need to be very long, but it or they can be entirely inside the lock frame 1A of the device cabinet lock, regardless of the position of the gear rack.
• the dotted lines 81 illustrate this in Figure 8.
• the gear rack (or gear racks) can also be so long, that it extends outside the lock frame 1 A.
• Such a gear rack (or gear racks) can be used as an additional latch or used to control an additional latch.
• the gear rack does not need indentation over its entire length, but the gear rack 9 can comprise and unindented section 9C, 10C, which extends outside the lock frame 1A.
• the latch 2 can thus in addition to the latch 2 be at least one additional latch or a controller for an additional latch.
• the plate can have a second deadlocking surface 7D, whereby the deadlocking means comprise a second gear rack 10, which has a second counter locking surface 10A for the second deadlocking surface 7D and a second indentation 10B, which is in contact with the gear wheel 8.
• the second gear rack 10 can also comprise an unindented section 10C, which extends outside the lock frame 1A.
• the device cabinet lock 1 also comprises a control means of the deadlocking means 5.
• the control means can be a second lock cylinder 6A or an electronic control device 6B.
• Figures 2 - 4 show the use of a lock cylinder 6A as a control means.
• Figure 2 shows a situation, where the latch 2 locks the lid/door of a device cabinet, compartment box or other cabinet.
• the racks 9, 10 are in this example used to control the additional latches, which are not shown in the figures.
• the free ends of the racks can also form the additional latches, if they are arranged to be in the frame of the compartment box/cabinet during locking.
• the second lock cylinder 6A is arranged to turn the plate 7 from the deadlocking position to the release position when turning a second key in the second lock cylinder 6A.
• a control shape 1 1 which controls the plate 7 via the control protrusion 7A when the second key, i.e. the key meant to be used in the second lock cylinder, is turned.
• Figure 3 shows a situation, where the second key has been turned, which has caused the turning of the control shape 11.
• the control shape is in this example a peg.
• the control shape 11 When turning, the control shape 11 simultaneously turns the plate 7, whereby it turns away from the deadlocking position.
• the deadlocking surface or surfaces 7C, 7D of the plate are not against the locking rack or racks, and the key can be turned in the lock cylinder 4.
• the lock cylinder and its turning axis or the thereto connected turning axis 3 turn, whereby also the latch 2 and gearwheel 8 orgearwheels connected to the turning axis turn.
• the gear wheel in turn moves the racks 9, 10, whereby also the additional latches move away from the locking position.
• Figure 4 illustrates such a situation.
• Springs for different purposes can also be placed in the device cabinet lock 1.
• a spring can for example be used for turning the plate 7 toward the deadlocking position, where its deadlocking surface(s) is against the counter surface(s) 9A, 10A of the rack(s).
• a spring or springs can also be used for keeping the latch 2, racks 9, 10 and centre axis 3 in the locking position.
• FIGs 5 - 7 illustrate the operation of the electronic control device.
• the electronic control device 6B is arranged to form a power transmission connection from the entity formed by the turning axis 3 and the latch 2 to the plate 7 in order to turn it from the deadlocking position to the release position when turning a key in the lock cylinder 4.
• the electronic control device 6B has made it possible for the plate 7 to be turned away from the deadlocking position, whereby it has been possible to move the latch 2 and the racks 9, 10 away from their locking positions.
• the embodiment of the figures comprises a control part 12, which is connected in a turning manner to the device cabinet lock, and which is placed between the entity formed by the turning axis 3 and latch 2 and the electronic control device 6B.
• the electronic control device 6B is connected to the control protrusion 7B for example with a screw fastening.
• the electronic control device 6B is arranged to form a power transmission connection between it and the control part 12 as a response to electronic controlling.
• the electronic control device 6B is an electromagnet or a solenoid.
• the embodiment of the figures uses an electromagnet. When control electrical current is connected to the electromagnet or other electronic control device, it generates an electromagnetic force, which makes possible the turning of the plate 7.
• Figure 6 shows a situation, where the electromagnet is de-energized, and an attempt has been made to turn the lock cylinder 4 with a key. Thus, the turning axis 3 and simultaneously the latch 2 are slightly turned, but are still in the locking positions, because there is no power transmission connection between the control part 12 and the electromagnet.
• Figure 6 shows a clear gap 61 between the control part 12 and the electromagnet, while the control part 12 is also slightly turned due to the slight turning of the latch and turning axis.
• a control current is connected to the electromagnet 6B, then the electromagnet forms an electromagnetic field, via which the electronic control device and control part are in power transmission connection.
• the control part is for example iron, whereby the electromagnetic field keeps the control part 12 and electromagnet (or solenoid) attached to each other.
• turning the latch and turning axis which thus also turns the control part 12, turns the plate 7 away from the deadlocking position, as is shown in Figure 7.
• the plate 7 can comprise a second control protrusion 7A, 7, whereby the device cabinet lock can have both a second lock cylinder 6A and an electronic control device 6B.
• the second lock cylinder and electronic control device are arranged to operate with the control protrusions 7A, 7B for example in the manner shown in the figures.
• the control protrusions can be formed so that they are well suited for use with the control means meant for them. Other functions can additionally be achieved with the control protrusions. From the figures can for example be seen that the control protrusion 7A meant for the second lock cylinder can also comprise a side protrusion, which functions with a micro switch placed in the device cabinet lock.
• the device cabinet lock can be one or two control devices in the device cabinet lock for controlling deadlocking.
• An advantage of the electronic control device is that it can be used to control the device cabinet lock to be out of the deadlocking for example during a certain time, whereby it can be opened only by using one key, i.e. the cylinder lock key.
• An advantage of the second lock cylinder is for example that the device cabinet lock does not need electrification.
• the device cabinet lock according to the invention can be realized in many different ways, as can be discerned from the description above.
• the invention makes possible a better safety level of the device cabinet lock than in known solutions in a cost-efficient way.
• the invention additionally makes possible the forming of different device cabinet lock variations.
