Definitions

  • the present invention relates to a safety lock for a hinged closure member, such as a gate or door, especially for outdoors use.
  • a known safety lock comprises: a lock assembly configured to be mounted on the hinged closure member and comprising a latch bolt moveable between a latching position and an unlatching position; a latch bolt actuating mechanism configured to move the latch bolt from its latching position to its unlatching position, the latch bolt actuating mechanism comprising: a first driver mounted on a first side of the lock assembly; and a second driver mounted on a second side of the lock assembly, said second side being opposite said first side; and a blocking mechanism having a blocking state and an unblocking state, the blocking mechanism being configured to be selectively mounted in a first position on said first side of the lock assembly to prevent the first driver from moving the latch bolt to its unlatching position when the blocking mechanism is in its blocking state and in a second position on said second side of the lock assembly to prevent the second driver from moving the latch bolt to its unlatching position when the blocking mechanism is in its blocking state.
  • Such a free-exit safety lock is disclosed in EP 2 886 755 with a blocking mechanism being formed by a pushbutton combination mechanism.
  • the handle i.e. the driver
  • drives a pivotable lever by intermediary of a square spindle, which engages a first pin provided on the latch bolt.
  • the free end of the pivotable lever extends above the latch bolt and may be engaged by the pushbutton combination mechanism.
  • the pushbutton combination mechanism includes a check slider which engages the free end of the pivotable lever and which slides, when the correct code is entered using the pushbuttons, away from the pivotable lever thus allowing this lever to pivot to unlatch the latch bolt.
  • the free-exit side i.e.
  • the handle i.e. the driver
  • drives a pivotable lever by intermediary of a spindle and a lever, which engages a second pin provided on the latch bolt, in particular on the opposing side of the latch bolt when compared to the first pin.
  • a downside of the known safety lock is that a series of steps are required in order to change the free-exit and non-free-exit side of the safety lock. More specifically, the pushbutton combination mechanism needs to be opened, removed from one side and replaced on the other side. At the same time, also the handles need to be reversed since the free-exit handle would otherwise be located at the side of the pushbutton combination mechanism.
  • the latch bolt actuating mechanism comprises: a first spindle extending through the lock assembly and being rotatable about its longitudinal axis in an unlocking direction to move the latch bolt from its latching position to its unlatching position, the first spindle having a first end and a second end, the first driver being coupled to the first end of the first spindle when the blocking mechanism is in its second position and the second driver being coupled to the first end of the first spindle when the blocking mechanism is in its first position; a second spindle extending away from the first spindle and being rotatable about its longitudinal axis in said unlocking direction, the second spindle having a first end and a second end with the second end of the second spindle being adjacent the second end of the first spindle, the first driver being coupled to the first end of the second spindle when the blocking mechanism is in its first position and the second driver being coupled to the first end of the second spindle when the blocking mechanism is in its second position, the blocking mechanism, when in its
  • the latch bolt actuating mechanism relies on a multi-part spindle with at least a part (i.e. the first spindle) which can rotate independently from the other part (i.e. the second spindle).
  • This allows positioning the blocking mechanism to only prevent a rotation of the second spindle while allowing the first spindle to rotate freely.
  • the driver coupled to the first spindle may thus form a free-exit while the driver coupled to the second spindle can only be operated after having unblocked the blocking mechanism.
  • the latch bolt actuating mechanism further comprises a very limited number of moving elements, namely the multi-part spindle (typically two parts, although three parts may be required when blocking mechanisms are provided on both sides of the lock assembly) together with two followers (or four when blocking mechanisms are provided on both sides of the lock assembly) and one (or two) couplers. Furthermore, these elements do not require any sliding motion, which is known to be prone to problems in outdoors applications (e.g. due to water, dirt, etc. causing increased friction).
  • latch bolt actuating mechanism Another advantage of the latch bolt actuating mechanism is that all parts of the multi-part spindle are in line with one another thus allowing the drivers to be positioned at a same height on both sides of the lock assembly. Furthermore, all spindle parts undergo a same rotation when unlatching the latch bolt. As such, in case the drivers comprise a handle, the lock assembly may be unlatched by performing a same rotation of the handle on each side of the lock assembly.
  • the first spindle is rotatable in the unlocking direction irrespective of the state of the blocking mechanism. This results in a free-exit side of the lock assembly, i.e. anyone can unlatch the latch bolt from the side of the lock assembly on which no blocking mechanism is present.
  • the safety lock comprises a further blocking mechanism having a blocking state and an unblocking state, the further blocking mechanism being configured to be selectively mounted in a first position, when the blocking mechanism is in its first position, on said second side of the lock assembly to prevent the second driver from moving the latch bolt to its unlatching position when the further blocking mechanism is in its blocking state and in a second position, when the blocking mechanism is in its second position, on said first side of the lock assembly to prevent the first driver from moving the latch bolt to its unlatching position when the further blocking mechanism is in its blocking state
  • the latch bolt actuating mechanism further comprising: a third spindle extending away from the first spindle and being rotatable about its longitudinal axis in said unlocking direction, the third spindle having a first end and a second end with the second end of the third spindle being adjacent the first end of the first spindle, the second driver being coupled to the first end of the third spindle when the further blocking mechanism is in its first position and the first driver being coupled
  • a safety lock is provided with additional blocking mechanisms on both sides of the safety lock, while relying on a single multi-part spindle (i.e. at least three parts) to allow unlatching the latch bolt from either side of the safety lock independent from the other side.
  • a single multi-part spindle i.e. at least three parts
  • the coupling means comprise a leader protrusion provided on the second spindle follower and a follower protrusion provided on the first spindle follower, the leader protrusion being configured to engage the follower protrusion to rotate the first spindle follower in said unlocking direction when the second spindle is rotated in said unlocking direction.
  • the follower protrusion is preferably formed by a separate element mounted on first spindle follower in a first location when the blocking mechanism is in its second position and in a second location the blocking mechanism is in its first position, the first location and the second location being on opposite sides of the leader protrusion.
  • Relying on a leader and follower is a simple and robust construction for transferring the rotation from the second spindle to the first spindle while allowing the first spindle to also rotate independently. Furthermore, since the unlocking direction is determined by the lock assembly itself and because, when changing the placement of the blocking mechanism, the second spindle is moved to the other side of the lock assembly, the coupling means need to be modified in order to enable transferring the rotation from the second spindle to the first spindle.
  • Using a follower placeable in two positions provides a simple way to adapt the latch bolt actuating mechanism to the placement of the blocking mechanism.
  • the blocking mechanism comprises a check slider which is moveable between a blocking position and an unblocking position, wherein the check slider, when in its blocking position, is configured to prevent a rotation of the second spindle.
  • the check slider provides a reliable linkage between the blocking mechanism and the latch bolt actuating mechanism.
  • the second spindle follower has a non-cylindrical outer surface, the check slider, when in its blocking position, engaging said non-cylindrical outer surface. It is advantageous to use the second spindle follower to prevent rotation of the second spindle as this follower has an increased dimension (i.e. it is disposed around the second spindle) thus allowing a larger contact surface with the check slider, which reduces the malfunction risk.
  • the check slider is spring biased towards its unblocking position
  • the blocking mechanism further comprising an electrically operated lever moveable between an engaging position in which the lever engages the check slider to keep the check slider in its blocking position and a releasing position.
  • the blocking mechanism is user-operated to change between its blocking state and its unblocking state. This allows a user to locally unlatch the latch bolt when desired, which may not be the case when the blocking mechanism is controlled from a central command.
  • the blocking mechanism comprises at least one of a mechanically operated mechanism, such as a key-operated mechanism or preferably a pushbutton combination locking mechanism, or an electrically operated mechanism, such as a card-reader, a fingerprint scanner, a wireless receiver, for example a Bluetooth receiver, configured to receive unlocking instructions (e.g. sent from a smartphone or the like), or preferably a pushbutton combination locking mechanism.
  • a mechanically operated mechanism such as a key-operated mechanism or preferably a pushbutton combination locking mechanism
  • an electrically operated mechanism such as a card-reader, a fingerprint scanner, a wireless receiver, for example a Bluetooth receiver, configured to receive unlocking instructions (e.g. sent from a smartphone or the like), or preferably a pushbutton combination locking mechanism.
  • each driver comprises a handle which is fixed to the first end of a respective one of the spindles.
  • Handles are a common way to unlatch a latch bolt. Furthermore, fixing these directly to a respective spindle avoids the requirement of intermediary parts thus simplifying the design.
  • the first spindle and/or the second spindle have a square cross-section which preferably has a side length of about 8 mm, the first end of the first spindle and/or the first end of the second spindle particularly comprising a slotted region.
  • one or both spindles are in conformity with European industry standards thus allowing them to be used with any desired handle. This also allows a user to use a same handle design on different closure members in the same area (e.g. as part of a same gated-off area or in a building) even though the safety lock is only used on one of the closure members.
  • the lock assembly further comprises a dead bolt which is preferably key-operated. This allows locking the closure member irrespective of the blocking mechanism.
  • the blocking mechanism when in its unblocking position, does not prevent rotation of the second spindle.
  • a closure system comprising a support; a closure member, in particular a gate, hingedly mounted on the support; and the safety lock as described above.
  • the closure member comprises a hollow tubular member, the lock assembly being mounted inside the hollow tubular member.
  • the lock assembly is thus preferably a morticed lock assembly which is aesthetically pleasing, which further improves the security as the lock assembly is not accessible from the outside, and which also is more space efficient than a surface mounted lock assembly.
  • the closure system further comprises a latch keeper assembly mounted on the support, the latch keeper assembly comprising a closure member stop and the safety lock comprising an escutcheon mounted on a same side of the lock assembly as the blocking mechanism, the escutcheon comprising a stopping region configured to engage at least a part of said stop, said stopping region being preferably located between the driver on said same side of the lock assembly and an input means of the blocking mechanism.
  • the safety lock can be fitted on a narrow closure member where there is not necessarily sufficient area of the closure member available adjacent the safety lock to act as a stopping surface. It further avoids having to provide an overly long closure member stop which extends beyond the total height of the safety lock which would be required if no part of the safety lock may be used as a stopping surface.
  • FIGS 1A to 1C show different views of a closure system comprising a safety lock 40 according to the present invention.
  • the closure system generally comprises a moveable closure member 20, such as a gate, a door, or a window, attached to a fixed support 10 such as a wall or a post.
  • the closure system typically also includes a further fixed support 30 such as a wall or a post.
  • the safety lock 40 is typically mounted on the moveable closure member 20 and a keeper assembly 48 is provided on the further fixed support 30, although the placement can also be reversed.
  • the keeper assembly 48 is shown in figures 2A and 2B and is configured for receiving a latch bolt and, optionally, a dead bolt of the safety lock 40.
  • the keeper assembly 48 may be a surface-mounted keeper assembly disclosed in EP 3 239 440 or in EP 1 600 584 .
  • the keeper assembly 48 may also be a surface-mounted keeper assembly disclosed in European patent applications 21200493.1 or 21200445.1 which are not yet published.
  • the keeper assembly 48 may also be a morticed keeper assembly fitted in the support 30 as disclosed in European patent application 22162702.9 which is not yet published.
  • Figures 2A and 2B further illustrate that the safety lock 40 may comprise multiple operating mechanisms, including, but not limited to, a pushbutton means 42, a handle means 44 and a key-cylinder 46.
  • the key-cylinder 46 is optional in the context of the present invention and is usually only present in case the safety lock 40 is provided with a dead bolt.
  • the remaining operating mechanisms, i.e. the pushbutton means 42 (in general a blocking mechanism) and the handle means 44 (in general drivers), are always present in the safety lock 40 according to the present invention and both operate on a latch bolt of the safety lock 40. Further details on these are described below.
  • a first embodiment of a safety lock according to the present invention is shown in exploded view in figure 3 in a first configuration 100 and in figure 4 in a second configuration 100'.
  • the difference in configurations is to account for both right-handed and left-handed closure systems. More specifically, the configuration 100 shown in figure 3 is a safety lock for a right-handed closure system and the configuration 100' shown in figure 4 is a safety lock for a left-handed closure system. Both configurations of the safety lock rely on identical components and will be described jointly below.
  • the safety lock comprises a lock assembly 102.
  • the lock assembly 102 may be a surface-mounted assembly disclosed in EP 1 118 559 or in EP 2 915 939 .
  • the lock assembly 102 may also be a surface-mounted assembly disclosed in European patent applications 21212439.0 or 21212440.8 which are not yet published.
  • the lock assembly 102 may also be a morticed keeper assembly fitted in the closure member 20 as disclosed in EP 2 186 974 or in EP 3 216 953 .
  • the lock assembly 102 includes both a latch bolt 104 and a dead bolt 106.
  • the dead bolt 106 is of a rotating type in the illustrated embodiment with a hook-shaped element. However, a dead bolt of the sliding type may be also be used.
  • the dead bolt 106 is operated by means of a key cylinder 108 which is inserted through the lock assembly 102. Any conventional key cylinder 108 may be used, e.g. a single-barrel euro-profile cylinder as in the illustrated embodiment. Furthermore, as described above, the dead bolt 106 and key cylinder 108 may be omitted.
  • the latch bolt 104 of the lock assembly 102 is generally moveable between a latched position (shown in figures 3 and 4 ) and a retracted position.
  • the safety lock comprises a latch bolt actuating mechanism configured to move the latch bolt 104 from its latching position to its unlatching position.
  • the latch bolt actuating mechanism includes a first handle 130 (i.e. a first driver) and a second handle 132 (i.e. a second driver) located on opposing sides of the lock assembly 102 that are coupled to the latch bolt 104 by means of multi-part spindle described in detail below.
  • each handle 130, 132 is mounted on an opposing end of the multi-part spindle.
  • other components may be present between a handle and the multi-part spindle and/or that one or both handles are replaced with other drivers (e.g. a push bar, a button, or the like).
  • the lock assembly is also provided with two escutcheons 126, 128 that are fixed to the closure member 20.
  • the escutcheons 126, 128 provide a finish to the closure member 20 and aid in ensuring that any openings therein and any internal components of the safety lock are completely hidden and/or covered.
  • the safety lock according to the present invention further includes a blocking mechanism 134 that can be mounted on either side of the lock assembly 102 to block the operation of the handle on that side.
  • Figure 3 illustrates the blocking mechanism 134 on a first side of the lock assembly 102 in which case the operation of handle 132 may be prevented
  • figure 4 illustrates the blocking mechanism 134 on a second side (opposite the first side) of the lock assembly 102 in which case the operation of handle 132 may be prevented.
  • the blocking mechanism 134 can for example be mounted on the outside of the closure system to prevent unauthorized access.
  • the multi-part spindle includes a first spindle 110 extending between a first end 110a and a second end 110b and a second spindle 112 extending between a first end 112a and a second end 112b. Both spindles 110, 112 are in line with one another with the second ends 110b, 112b being adjacent one another. The free first ends 110a, 112a are used to mount a respective handle 130, 132.
  • the first spindle 110 extends through the lock assembly 102 and is rotatable in an unlocking direction (e.g. clockwise or counter clockwise depending on the lock assembly 102) to unlatch the latch bolt 104.
  • the second spindle 112 is located on opposing sides of the lock assembly depending on the placement of the blocking mechanism 134. In other words, the second spindle 112 is always positioned on the side of the lock assembly 102 where the blocking mechanism 134 is present with the blocking mechanism 134 allowing to prevent a rotation of the second spindle 112.
  • a first spindle follower 114 is mounted on the second end 110b of the first spindle 110 and a second spindle follower 120 is mounted on the second end 112b of the second spindle 112.
  • the second spindle follower 120 is provided with a leader protrusion 122 and a follower protrusion 118 is mounted on the first spindle follower 114.
  • the first spindle follower 114 is provided with two mounting openings 116a, 116b and the follower protrusion 118 is mounted in one of these depending on the configuration 100, 100' of the safety lock.
  • the follower protrusion 118 is mounted in opening 116a for a right-handed safety lock configuration 100 and in opening 116b for a left-handed safety lock configuration 100'. Due to this assembly, the first spindle 110 is free to rotate in the unlocking direction irrespective of the second spindle 112, while a rotation of the second spindle 112 causes a rotation of the first spindle 110 since the leader protrusion 122 engages the follower protrusion 118.
  • the safety lock thus has a free exit side where anyone can unlatch the latch bolt 104 with a blocking mechanism 134 being present on the other side.
  • both spindles 110, 112 are European industry standard spindles, i.e. they have a square cross-section with a side length of about 8 mm with their first ends 11a, 112a being slotted.
  • the slotted ends enable to fix the handles 130, 132 to the spindles 110, 112 using a set screw (indicated in figures 10 and 11 with reference numbers 360, 360', 460, 460'). In this manner, the handles 130, 132 cannot be pulled from their spindle 110, 112.
  • the spindle follower 114 further prevents the handle 130 from being pulled from the closure system. More specifically, in the illustrated embodiment, the spindle follower 114 engages an outer surface of the closure member 20. As the second end 110b of the first spindle 110 is slightly larger than the opening through the first spindle 110 (this may be achieved by having conical surfaces for example to provide a flush end face), a pulling force exerted on the handle 130 is transferred, via the first spindle 110, to the follower 114 which engages the closure member 20.
  • a similar principle is used for the second spindle 112 with a locally thickened second end 112b so that a pulling force exerted on the handle 132 is transferred to the follower 120 which engages an inner surface of the escutcheon 126 which is fixed to the closure member 20.
  • the length of the first spindle 110 i.e. the distance between its opposing ends 110a, 110b
  • the length of the first spindle 110 can be varied in order to account for thicker or smaller closure members 20.
  • the blocking mechanism 134 involves a pushbutton combination lock 136 and a check slider 138 which is slideable between a blocking state and an unlocking state.
  • the check slider 138 In the blocking state, the check slider 138, in particular a flat surface thereof, engages a flat surface 124 of the second spindle follower 120 thereby preventing a rotation of the second spindle follower 120.
  • Entering a correct sequence in the pushbutton combination lock 136 causes the check slider 138 to move to its unlocking state (i.e. by sliding upwards in the illustrated embodiment) thus allowing a rotation of the second spindle follower 120.
  • the skilled person is assumed familiar with the internal operation of a pushbutton combination lock an example of which is disclosed in EP 2 886 755 .
  • the escutcheon plate 126 is specifically designed to be compatible with the keeper assembly 48 (in particular a keeper assembly as disclosed in EP 3 153 645 ) and a mechanical blocking mechanism 134. More specifically, the escutcheon plate 126 comprises the following regions (going from top to bottom in figures 3 and 4 - the regions have been indicated in figure 10 ): a pushbutton combination lock cover - region 'a'; a first abutment region - region 'b'; a second spindle cover with an opening for the handle 132 - region 'c'; a lock assembly cover - region 'd'; and a second abutment region - region 'e'. When closed, the abutment regions engage a stop provided as part of the keeper assembly 48, which, as described above, is advantageous to allow existing keeper assemblies to be used with the safety lock in particular on a narrow closure member.
  • a second embodiment of a safety lock according to the present invention will be described with respect to figures 5A to 9 .
  • Elements of the safety lock which are identical to or which have the same function as elements in the first embodiment will be designated with the same last two digits but preceded with a '2' and will not be described.
  • the main difference between the first and second embodiments is the blocking mechanism. More specifically, where the first embodiment relied on a mechanical blocking mechanism, the second embodiment relies on an electrically operated blocking mechanism.
  • a main advantage of using an electrically operated blocking mechanism is that no mechanical coupling is required between the blocking mechanism input means and the lock assembly, thus alleviating design requirements, e.g. the escutcheon can be simplified.
  • FIGS 5A to 6B show outside views of a closure system comprising a safety lock 50 according to the present invention.
  • the closure system generally comprises a moveable closure member 20, such as a gate, a door, or a window, attached to a fixed support 10 such as a wall or a post.
  • the closure system typically also includes a further fixed support 30 such as a wall or a post.
  • the safety lock 50 is typically mounted on the moveable closure member 20 and a keeper assembly 48 is provided on the further fixed support 30, although the placement can also be reversed.
  • the safety lock 50 may comprise multiple operating mechanisms, including, but not limited to, a pushbutton means 42, a handle means 54 and a key-cylinder 46.

  • the remaining operating mechanisms i.e. the pushbutton means 42 (in general a blocking mechanism) and the handle means 54 (in general drivers), are always present in the safety lock 50 according to the present invention and both operate on a latch bolt of the safety lock 50. From these views, it is clear that the input means 42 of the blocking mechanism are located separately from the remainder of the safety lock.
  • the internal structure of the safety lock 50 is shown in figure 7 in a first configuration 200 and in figure 9 in a second configuration 200'.

  • control component 242 is coupled to a moveable lever 244, in particular a lever 244 which is pivotable about pivot 246 between an engaging position (shown in figure 8A ) and a releasing position (shown in figure 8B ).
  • An electromagnet (not shown) may be used to control the lever 244.
  • a check slider 238 is further provided which is spring-biased, by means of springs 254.
  • the check slider 238 has a flat engagement surface 250 which abuts, in particular to top side thereof, against a flat surface 224 of the second spindle follower 220.
  • the free end 248 of the pivotable lever 244 engages the flat engagement surface 250, in particular the bottom side thereof.
  • a recessed region 252 is provided adjacent the engagement surface 250.
  • the check slider 238 could be omitted with the free end 248 directly engaging the second spindle follower 220, in particular the flat surface 224 thereof.
  • FIG. 10 shows an exploded view of a safety lock with a mechanically operated double blocking mechanism, i.e. the blocking mechanism shown in figures 3 and 4 is present on both sides of the lock assembly.
  • Figure 11 shows an exploded view of a safety lock with an electrically operated double blocking mechanism, i.e. the blocking mechanism shown in figures 7 and 9 is present on both sides of the lock assembly.
  • Elements of the safety lock which are identical to or which have the same function as elements in the first and second embodiment will be designated with the same last two digits but preceded with a '3' ( figure 10 ) and a '4' ( figure 11 ) and will not be described.
  • the multi-part spindle has three spindle elements 310, 312, 312' and 410, 412, 412' (reference numbers with a 'prime' in figures 10 and 11 designate identical components on opposing sides of the lock assembly 302, 402). More specifically, the construction of the second spindle with spindle follower is present on both side of the first spindle, which is thus also provided with spindle followers on each end.
  • the latch bolt actuating mechanism in such an embodiment comprises two outer spindles 312, 312', 412, 412' the rotation of which can be prevented by a respective blocking mechanism 334, 334', 434, 434' and an inner spindle 310, 410 extending through the lock assembly 302, 402. Due to the spindle followers 314, 314', 320, 320', 414, 414', 420, 420' with leader protrusions and follower protrusions, a rotation of either outer spindle causes a rotation of the inner spindle, which inner spindle is free to rotate irrespective of the outer spindles.
