Definitions

  • the present invention relates to a mortice lock with a reversible latch bolt.
  • the lock comprises a housing provided with a non-circular opening and a latch bolt having a longitudinal axis.
  • the latch bolt has a main portion having a non-circular cross-section, which main portion is received in said non-circular opening to guide the latch bolt and to prevent it from turning around its longitudinal axis during operation.
  • the latch bolt is reversible between a left-handed and a right-handed position by turning it around its longitudinal axis.
  • the lock further comprises a guiding mechanism for the latch bolt enabling a reciprocating sliding movement of the latch bolt along its longitudinal axis between an extended and a retracted position, which guiding mechanism comprises said non-circular opening in the housing and a further guide provided in the housing.
  • the lock also comprises at least one latch bolt spring to urge the latch bolt towards its extended position and an actuation mechanism arranged to move said latch bolt from said extended to said retracted position against the latch bolt spring.
  • EP 2 186 974 discloses such a mortice lock in which the latch bolt is reversible.
  • a drawback of this type of locks is that the latch bolt is only reversible when a part of the front plate or the entire front plate of the lock, which comprises the non-circular opening, is removed thereby allowing to turn the latch bolt around its longitudinal axis.
  • removing the front plate of a lock is time consuming and a removable front plate has to be sufficiently strong, as such it requires more material, in particular stainless steel.
  • a removable front plate increases the costs for manufacturing the lock.
  • removing the front plate also entails having to remove the lock from the mortice which is time consuming. Further, it is also possible that during removal of the front plate, one or more of the screws attaching the front plate are lost due to carelessness of the person removing the front plate.
  • Mortice locks with reversible latch bolts for which the front wall does not have to removed are also known in the state of the art.
  • GB 2 439 783 discloses a mortice lock with a rectangular latch bolt which latch bolt can be pulled out of the housing. By pulling out the latch bolt it is possible for the latch bolt to be turned between a left-handed and a right-handed position before being inserted back into the lock.
  • a disadvantage of such locks is that more complicated internal mechanisms are needed that enable releasing the latch bolt from its guiding mechanism thereby enabling to take the latch bolt out of the housing, thus increasing the costs of the lock.
  • the more complicated internal mechanisms also increase the chance of a malfunction of the lock and as such these locks are less reliable.
  • This aim is achieved according to the invention with a guiding mechanism which enables to slide the latch bolt in the direction of its longitudinal axis against the latch bolt spring into a position wherein its main portion is disengaged from said non-circular opening and wherein the latch bolt is reversible by turning it around its longitudinal axis between said left-handed and right-handed position.
  • the latch bolt By pushing the latch bolt into the housing until its main portion is disengaged from the non-circular opening the latch bolt is no longer prevented from turning around its longitudinal axis so that the latch bolt can be easily turned from said left-handed to right-handed position and vice versa. Moreover, there is no need for an internal mechanism allowing to release the latch bolt or the front plate. As such, there is also no need to reinsert the latch bolt or reattach the front plate in a correct manner.
  • EP 2 778 323 discloses a lock for mounting into a tubular member, which has a latch bolt that is also reversible without having to remove the front wall or without having to remove the latch bolt from the housing.
  • this latch bolt is a cylindrical latch bolt which is reversible in all of its positions (e.g. the extended and retracted positions).
  • a disadvantage of such a lock is that the latch bolt can be turned when the gate is closed by inserting a pair of pliers between the gate and the tubular member and simply turning the latch bolt. Reversing the latch bolt when the gate is closed enables to open the gate by pushing against the gate as the latch bolt penetrates only with its bevelled top in the lock keep.
  • a lock according to the present invention does not have this drawback since the lock has a latch bolt with its main portion having a non-circular cross-section.
  • the lock further comprises a retainer which is irrotatably mounted in the housing and which is resiliently urged against said main portion of the latch bolt at least when said main portion is in its disengaged position and which is urged away from the centre of the latch bolt when the latch bolt is turned from its left-handed position to its right-handed position and vice versa.
  • This embodiment has the advantage that the retainer prevents an accidental rotation of the latch bolt during normal use. For example, it could be that due to an excessive force applied to the latch bolt during normal operation, e.g. slamming a gate shut, the latch bolt is pushed into the disengaged position and rotates to a small extent. This would then lead to a jammed latch bolt and a non-functional lock.
  • the retainer prevents this from happening by resiliently urging against the main portion to prevent such an accidental rotation.
  • said retainer comprises a ring portion extending around the latch bolt and at least one lip portion having a proximal end attached to the ring portion and a distal end which is resiliently urged against the main portion of the latch bolt.
  • said lip portion is resiliently bent away from the centre of the latch bolt when said latch bolt is turned from its left-handed position to its right-handed position and vice versa.
  • the ring portion of the retainer fits around the latch bolt so that the latch bolt is always centred with respect to the retainer.
  • the lip portion remains continuously in contact with the latch bolt during the reciprocating sliding movement of the latch bolt thereby always urging the latch bolt to remain in either the left-handed or the right-handed position. Further, as the lip portion bends resiliently outwards it also remains continuously in contact with the main portion of the latch bolt during rotation of the latch bolt. Moreover, when the latch bolt is turned from a right-handed to a left-handed position the lip portion starts urging the latch bolt to its left-handed position when the left-handed position is nearly reached. In fact, the urging of the lip portion ensures that the latch bolt snaps into its left-handed position when it is nearly reached thereby ensuring that the person reversing the latch bolt does not have to be very accurate.
  • said non-circular opening has an edge comprising at least two straight sections and the main portion of the latch bolt comprises at least two flat sides corresponding to these at least two straight sections.
  • said at least one lip portion is resiliently urged against one of said at least two flat sides in the left-handed position and against the other one of said at least two flat sides in the right-handed position.
  • the flat sides act as the urging point of the at least one lip portion and the lip portion can correspondingly urge against a different flat side depending on the right-handed or left-handed position of the latch bolt.
  • one of said two flat sides is used to effect closure of the gate by abutting with a gate keep when the latch bolt is in the right-handed position, while the other one of said two flat sides is used to effect closure of the gate by abutting with a gate catcher when the latch bolt is in the left-handed position.
  • said actuation mechanism comprises a stopping element which abuts against an element in the housing when the actuation mechanism slides the latch bolt into its retracted position and which prevents the actuation mechanism from sliding the latch bolt beyond its retracted position into its disengaged position.
  • the latch bolt does not enter its disengaged position by actuating the actuation mechanism, i.e. during daily use of the lock.
  • this provides an additional safety measure to prevent accidental rotation of the latch bolt as it cannot reach its disengaged position by the actuation mechanism. Therefore, there is a smaller chance that the latch bolt can get stuck by an accidental rotation in its disengaged position.
  • said latch bolt comprises a back portion irrotatably arranged in said further guide and rotatably connected to the main portion of the latch bolt.
  • the actuation mechanism comprises a lever which engages the back portion of the latch bolt to slide the latch bolt from its extended to its retracted position.
  • the main portion is free to rotate with respect to the back portion when it is in its disengaged position and it is not necessary to rotate the entire latch bolt but only the main portion of the latch bolt.
  • the lever engages with the back portion and does not need to account for differences in operation between the right-handed and the left-handed position of the main portion of the latch bolt.
  • said latch bolt further comprises a connecting portion which connects the main portion to the back portion, the connecting portion being screwed to said main portion and rotatably connected to said back portion and comprising a screw thread configured to cooperate with a further screw thread arranged on the main portion of the latch bolt, which screw thread and further screw thread enable adjusting the distance between said main portion and said back portion.
  • the distance between the main portion and the back portion of the latch bolt is adjustable it is possible to compensate for a larger or a smaller distance between a closure member, wherein the lock has been placed, and a gate keep.
  • the latch bolt comprises a hole extending from its front surface to the connecting portion enabling to rotate the connecting portion with respect to the main portion through the hole.
  • the hole is provided in the front surface of the latch bolt, the distance between the main portion and the back portion can be adjusted at any time when the closure member is open, even after the lock has been placed in a mortice, without having to open the housing of the lock or without having to remove the lock.
  • the invention generally relates to a mortice lock 1 comprising a housing 2 and a reversible latch bolt 3.
  • mortice lock is used to indicate that the lock is to be inserted in a mortice, i.e. a recess in a door or an opening in a tubular member.
  • the closure member is a hinged closure member which is fixed by means of hinges to a support.
  • the mortice lock 1 of the present invention is configured to be mounted through a slot 4 in a wall portion of a tubular member 5.
  • This tubular member 5 can be part of a gate, for example as illustrated in Figures 1 and 2 .
  • the lock 1 may comprise a deadbolt 6 which is operated by means of a key, in particular through the intermediary of a lock cylinder.
  • the deadbolt 6 is slidably mounted in the lock 1 to slide between a retracted and an extended position.
  • the deadbolt 6 is however hook-shaped and pivots in the lock 1 between its extended and its retracted position. This type of deadbolt 6 is already known from the prior art. Reference can be made to the lock disclosed in EP 2 186 974 which is incorporated herein by way of reference.
  • the lock 1 comprises, besides the housing 2 and the latch bolt 3, a guiding mechanism for the latch bolt 3, a latch bolt spring 7, and a latch bolt actuation mechanism 8.
  • the latch bolt 3 has a longitudinal axis 9.
  • the latch bolt 3 can be a one-piece structure, but a latch bolt 3 comprising a main portion 10 and a back portion 11, which can rotate with respect to one another, is preferred.
  • the back portion 11 can help guide the latch bolt 3.
  • the latch bolt 3 also comprises a connecting portion 12.
  • the three-part structure of the latch bolt 3 enables to adjust the distance between the main portion 9 and the back portion 11 as will be detailed below.
  • the housing 2, the latch bolt 3, and the deadbolt 6 are preferably made from stainless steel.
  • the guiding mechanism of the latch bolt 3 is formed by a non-circular opening 13 in the housing 2 which receives the main portion 9 of the latch bolt and two elongated slots 14 in the housing which each receive a part of the back portion 11 of the latch bolt 3.
  • Figures 6 and 8 show the lock 1 from opposite perspective views and each view shows one of the two elongated slots 14 in the housing 2.
  • the guiding mechanism enables a reciprocating sliding movement of the latch bolt 3 along its longitudinal axis 9 between an extended, a retracted, and a disengaged position.
  • the extended position of the latch bolt 3 is shown in Figures 4 and 5
  • the retracted position of the latch bolt 3 is shown in Figures 6 and 7
  • the disengaged position is shown in Figure 12 .
  • the actuation mechanism 8 is turned, e.g. by turning a handle (not shown) inserted in the actuation mechanism 8, which in turn displaces a latch bolt lever 26.
  • the latch bolt lever 26 is arranged to engage with the back portion 11 of the latch bolt 3 and slides the back portion 11 into the housing thereby sliding the entire latch bolt 3.
  • the actuation mechanism 8 comprises an arm 27 which rotates together with the actuation mechanism 8 and abuts with a retainer a pin 18 inserted in a retainer 17, discussed below. Because the arm 27 abuts with the pin 18 the actuation mechanism 8 cannot slide the latch bolt 3 beyond this point.
  • the arm 27 functions as a stop of the actuation mechanism 8 thereby defining the retracted position of the latch bolt 3.
  • This stopping function of the arm 27 could also be achieved with a differently orientated arm abutting against an element, not necessarily the pin 18, in the housing 2.
  • the arm 27 could abut against a ridge inside the housing 2.
  • the travel distance of the back portion 11 between the extended and the retracted position is determined by the position wherein the arm 27 abuts with the retainer 17. Therefore, during normal operation of the actuation mechanism 8 the latch bolt 3 does not reach its disengaged position and thus cannot rotate with respect to its longitudinal axis 9.
  • the housing 2 comprises a non-circular opening 13.
  • the non-circular opening 13 has an edge comprising at least two straight sections 15 and the main portion 10 of the latch bolt 3 has a corresponding non-circular cross-section having two flat sides 16.
  • the lock 1 of the present invention has a reversible latch bolt 3 it is beneficial to have at least two flat sides 16 so that one of said two flat sides 16 abuts with the gate keep in the right-handed position of the latch bolt 3 and the other one of said two flat sides 16 abuts with a gate keep in the left-handed position of the latch bolt 3.
  • the non-circular opening 13 preferably has a corresponding shape to the main portion 10 of the latch bolt 3.
  • the non-circular opening 13 could also prevent rotation of the latch bolt 3 with only one flat section 15, but this would leave space between the latch bolt 3 and the non-circular opening 13 allowing dirt, e.g. sand, water, etc. to enter the housing 2.
  • the latch bolt spring 7 urges the latch bolt 3 towards its extended position.
  • the actuation mechanism 8 is used to move said latch bolt 3 from said extended to said retracted position against the latch bolt spring 7. Again, the workings of this type of actuation mechanisms 8 is known in the prior art and need not be discussed further.
  • FIG 16 shows a lock 1 according to an embodiment of the present invention.
  • Figures 17 and 18 illustrate a possible malfunction of this embodiment.
  • the latch bolt 3 is in its disengaged position and has rotated a small amount around its longitudinal axis 9 but not enough to turn be in either the left-handed or the right-handed position. This slight rotation can happen accidently, e.g. when a closure member is slammed shut and the latch bolt 3 moves into the disengaged position due to the force of slamming the closure member.
  • the latch bolt 3 is not in either one of the left-handed or the right-handed position the main portion 10 of the latch bolt 3 cannot re-engage with non-circular opening 13.
  • the latch bolt 3 is stuck inside the housing 2.
  • the lock 1 further comprises a retainer 17, as shown in Figures 3 to 15 .
  • the retainer 17 has an overall cuboid shape ensuring that it is irrotatably mounted in the housing 2.
  • the retainer 17 is fixed to the housing using a pin 18 inserted through an opening in the retainer 17 and two corresponding openings (not shown) in the housing 2.
  • the retainer 17 is further fixed to the housing using a second pin 19.
  • the retainer 17 is mounted adjacent to the non-circular opening 13 in the housing 2.
  • the lever 26 of the actuation mechanism 8 also abuts with the retainer 17 in the extended position, as illustrated in Figure 5 .
  • the retainer 17 comprises a ring-shaped opening 20 through which the latch bolt 3 slides and two lips 21.
  • the lips 21 each have a proximal end attached to the ring-shaped opening 20 and a distal end urging against the flat sides 16 of the latch bolt 3.
  • the lips 21 extend from their proximal end to their distal end substantially parallel to said longitudinal axis 9.
  • the ring-shaped opening 20 ensures that the retainer 17 is always centred around the main portion 10 and thus the lips 21 are always in contact with the flat sides 16.
  • the latch bolt 3 can be pushed against the latch bolt spring 7 into a position wherein its main portion 10 is disengaged from said non-circular opening 13 and wherein the main portion 10 of the latch bolt 3 is reversible between a left-handed and a right-handed position by turning it around its longitudinal axis 9.
  • Figures 12 , 13 and 15 illustrate how the main portion 10 of the latch bolt 3 is turned from a left-handed to a right-handed position, while Figure 14 shows a detailed view of the latch bolt 3 in an intermediate position.
  • the first step in turning the latch bolt 3 is to insert an external tool 22, for example an Allen key, in an opening 23 in the front surface of the latch bolt 3.
  • the tool 22 grips in a hexagonal socket 28 shown in Figure 11 .
  • the latch bolt 3 is slidable into its disengaged position wherein the main portion 10 is pushed completely into the housing 2 thereby disengaging the main portion 10 from the non-circular opening 13.
  • one of the lips 21 is always urging against one of the flat sides 16 of the main portion 3, even in the disengaged position.
  • This lip 21 prevents accidental rotation of the main portion 10.
  • the external tool 22 when using the external tool 22 to rotate the main portion 10 bends the lips 21 away from the centre of the latch bolt 3.
  • Figure 14 show one of the lips 21 bending outwards when the main portion 10 of the latch bolt 3 is in an intermediate position between the left-handed and the right-handed position.
  • the latch bolt 3 is reversible at any time either before or after having inserted the lock 1 into the tubular member 5 when the closure member is not in the closed position. Moreover, the entire operation takes only a few seconds to execute.
  • the latch bolt 3 comprises a main portion 10, a back portion 11, and a connecting portion 12.
  • the separate portions are shown in the exploded view of Figure 3 , while a cross-sectional view is shown in Figures 10 and 11 .
  • the back portion 11 has an opening which allows the back portion 3 to be placed on the connecting portion 12.
  • the connecting portion 12 is partly flanged thereby rotatably mounting the back portion 11 on the connecting portion 12.
  • the top part of the connecting portion 12 has a screw thread 24 which cooperates with a further screw thread 25 on the inside of the main portion 10.
  • the lock 1 is arranged to be mounted in a square tubular member 5.
  • this type of lock 1 is designed for closure members, such as a gate e.g. in a garden fence, the lock 1 preferably fits into a square tubular member 5 having an inner width of less than 40 mm.
  • the lock 1 can also be used in rectangular tubular members 5 which have a larger inner width.
  • the tubular member 5 has a square cross-section the distance between the side walls of the housing 2 also has be less than 40 mm to fit in a tubular member 5 of 40 mm. This certainly has to hold for the area near the main portion 10 of the latch bolt 3.
  • the housing 2 has, at the location of the main portion 10, an inner width between 5% and 30% and preferably between 10% and 20% larger than the diameter of the circumscribed circle around the main portion 10 of the latch bolt 3. This fractionally larger distance enables the main portion 10 of the latch bolt 3 to rotate inside the housing 2 and allows the retainer 17 to be placed around the main portion 10, which as discussed above helps the function of the lips 21 in preventing an accidental rotation of the main portion 10 of the latch bolt 3.
  • the diameter of the circumscribed circle around the main portion 10 of the latch bolt 3 is between 5% and 35% and preferably between 10% and 25% larger than the diameter of the inscribed circle in the main portion 10 of the latch bolt 3.
