- the present invention consists in a door with a lock or lock assembly, as herein described, fitted, with reference to any one or more of the accompanying drawings.
- the present invention consists in a building with a lock or lock assembly as herein described, fitted, with reference to any one or more of the accompanying drawings
- the present invention consists in a building including a door with a lock as herein described with reference to one or more of the accompanying drawings.
- the present invention consists in a plurality of locks as herein described with reference to one or more of the accompanying drawings wherein the locks have a common power supply supplying electricity to each lock in series.
- the term "failsafe” is referred to, this is taken to mean the lock will be releasable form the door jamb when there is a removal of power to the lock.
- the term “failsecure” is referred to, this is taken to mean the lock will not be releasable from the door jamb when there is a removal of power to the lock.
- Figure 1 is a side view of a lock with the cover being removed showing the disposition of the locking internals and sensing locations with the door closed, latch bolt extended, solenoid retracted (i.e. power on) to retract the locking bar (i.e. the lock is configured in a "failsecure” condition), latch bolt actuating means unactuated,
- Figure 2 shows a close up of the solenoid and locking bar similar to that of Figure 1 except that the locking bar is extended with a retracted position of the solenoid (i.e. the power is on and the lock is in a "failsafe" configuration)
- Figure 3 shows a similar configuration to that of Figure 1 with the exception that the solenoid has been extended (i.e. power off) and thus the locking bar is extended to block rotation of the latch bolt actuating means, (i.e. a "failsecure" configuration)
- Figure 4 is a similar view to that of Figure 2 whereby the lock in a "failsafe" configuration is shown in full side view,
- Figure 5 shows a further embodiment of the present invention in plan view being that of basic electric lock having only monitoring of the locking bar position, and in particular the locking bar position being monitored from the pinion gear and the signal output (either locally e.g. visually or remotely via electrical signal) is in serial with the micro switch so that the signal will only change from one status to the next on the condition that the micro switch (or other sensing means) for the locking bar is in one position or the other,
- Figure 6A shows an example of the circuit diagram for monitoring the condition of features of the lock, and local depiction and a single signal, the status decision of the lock being made locally by a controller
- Figure 6B shows an example of the circuit diagram for monitoring the condition of features of the lock, and remote depiction and multiple signals being output from the lock, for remote status decision making, and
- Figure 7 shows a plurality of locks in doors, installed in a building. With reference to Figures 1 through 7 is shown an electronically operatable
- the lock assembly 1 has a lock face 2 which is present on the peripheral edge of the door allowing the engagement of the latch bolt 19 within a complimentary receiving member in the door jamb.
- the lock assembly has a back 4, the lock assembly from the face to the back being recessed into the door periphery, also known as a mortice lock.
- the lock assembly consists of a lock housing 3 within which are housed the components of the lock assembly, namely a locking bar actuating means or drive means 5 which in this case is an electrically activated solenoid which consists of a external coil and an internal core.
- a locking bar actuating means or drive means 5 which in this case is an electrically activated solenoid which consists of a external coil and an internal core.
- Upon application of electrical power to the external coil drives the internal core up into the external coil (i.e. retraction).
- a biasing means 6 in this case a coil spring, the core is urged out from the solenoid to extend there from.
- Carried or actuated by the core of the solenoid is a drive plate 7 which is guided by a spigot 10.
- the drive plate 7 in turn activates a locking bar 8 via a pinion gear 9 and rack 11 selectively to block or unblock with a locking piece 25 the latch bolt actuating means 12 dependent upon whether the lock is in a "failsafe" or "failsecure” configuration.
- the locking bar 8 prevents the latch bolt actuating means 12 from actuating the latch bolt 19. In the position shown in Figure 1 the locking bar 8 and locking piece 25 are withdrawn and not blocking the latch bolt actuating means 12 and therefore the latch bolt actuating means 12 is unlocked, whilst in Figure 3 the locking bar 8 is blocking the latch bolt actuating means 12 and thus the lock is in a locked condition.
- the latch bolt activating means 12 consists of two similar pieces in plan which are split vertically perpendicular to their axis of rotation. Thus two independent means to actuate the latch bolt exist; each actuable by a (in this instance) square split shaft (not shown) from each side of the lock assembly. Each square shaft may in turn be activated by, for example, a handle, thus depending on the location and position of the locking piece 25 behind the split hub, each half of the split hub 12 may either be allowed to rotate or not.
- Sensed off each of the override blocks is the position of each half of the split hub. In the preferred embodiment this is sensed via latch bolt actuating means micro switches 28 (one behind the other in the figures shown). Other equivalent sensing means may also be used and are within the scope of this invention.
- the position of the latch bolt 19 is monitored, in this case, by one micro-switch.
- the micro-switch 14 registers the condition that the latch bolt 19 is fully extended, or that it is not fully extended from the housing 3. Additional micro-switches may be used if required to sense the latch bolt being fully retracted into the housing.
- a reed switch 15 in the housing 3 of the lock assembly 1 is activated, when the door is closed, by a magnetic presence in the door jamb or similar to register when the door is in a closed condition or in an open position. Any other form of proximity sensor may be used however such as electro-optical, magnetic or electro-mechanical.
- a solenoid sensor 16 senses the condition of the solenoid 5, that is whether the solenoid plunger is fully retracted or not.
- a further micro-switch 17 registers the location of the locking bar 8.
- the lock may be overridden by a key via a tumbler 300.
- An over-ride slider 301 senses the local over ⁇ riding via the tumbler 300.
- the tumbler may be activated by a key or similar mechanical means (e.g. a hand latch) or by electronic or electric means, e.g. by a swipe card, hand, finger, fingerprint or retinal scanning or similar.
- statii of each of the sensing means is fed back to a control PCB 18 and depending on the set up of the lock (eg "failsafe” or “failsecure”) the remote and local indications are output accordingly.
- each of the parallel circuits monitoring the lock feature conditions may be output as multiple signals to a remote location. This enables exact monitoring of the lock status at the remote location and a decision can be made there as to the locked or unlocked nature of the lock, based on the desired combination of feature conditions.
- Such a status signal would be to an LED registering fully locked as red and green if one condition is not met, i.e. unlocked. Or at a remote sensing location such as the central control station a lower voltage will indicate the failure of one or all of the conditions and a higher voltage will indicate that the successful meeting of all conditions to thus control a visual indication at the remote location.
- the status of each feature condition can be both locally or remotely displayed.
- the local display may be a two colour LED for each of the features monitored and the remote depiction may be similar.
- the remote location receiving multiple signals, one each for the feature conditions monitored in the lock. This may be output, for example by a number or wires, each for a particular signal of feature condition in the lock, and a ground wire or reference wire.
- the voltage levels are in reference to a ground reference wire, of for example OV.
- the DC voltage levels are 0 and 12, but may be any particular set of levels desired.
- the lock, sensors and control electronics are configurable such that any configuration of conditions may control any visual or remote indication of lock status.
- the reed switch may be a normally open or normally closed switch, or the voltage output for remote sensing may be high for unlocked and low for locked.
- the setting of these conditions is achieved by a control means e.g. a DIP (dual in line position) switch on PCB 27.
- a DIP switch is externally selectable in the preferred embodiment.
- the voltage output to the remote monitoring location may vary between a number of, discrete levels, each discrete level indicating a particular combination of sensed locations. The particular combination may be set with a particular combination DIP switches.
- the local depiction LED's may display a differing sequence of display, each differing sequence unique to a particular lock configuration and such remote and local depiction can be used to determine the lock status and/or fault finding.
- FIG. 5 A further preferred embodiment as shown in Figure 5 whereby the lock is in what could be termed a "basic electronic lock" configuration.
- the sensing means 35 for the locking bar 8 is located to sense the location of the pinion gear 9 (or alternatively the position of the drive plate 7) so that a positive signal indication can be obtained for the position of locking bar 8.
- the output signal (whether locally, visually or remotely electrically) is in series or senses the micro switch output and will only change from one status (e.g. open) to another (e.g. closed) dependent upon the changing of the status of the micro switch.
- the sensing means are located serially one after the other so that a fully broken (or unbroken) circuit is required to indicate one or either of the statii (i.e. locked or unlocked).
- the lock is there fore able to link a serial combination of monitored feature staii to produce one signal, for remote or local depiction of lock unlocked or locked status.
- the lock is able to output parallel multiple signals for remote indication of each of the lock features monitored. From these signals a decision can be made as to the lock being locked or not.
- the electric lock has an electrical isolation between the electricity entering (e.g. for powering and/or signalling the lock) and the internals of the lock and the signal which activates the lock itself.
- Such an electrical isolation is also known as galvanic isolation and can be achieved by various means known in the art such as but not limited to relays, opto couplers or solid state relays. In the preferred embodiment of the present invention the electrical isolation is achieved by solid state "telecom" relay.
- the lock therefore can form part of a series of locks 1 installed in doors 20 in a building or buildings 310.
- the status of each lock can be locally or remotely depicted as locked or unlocked. Additionally the conditions of each feature within the lock 1 can be locally or remotely depicted.
