    "Door lock unit adapted to be mounted on a tubular member"
    This invention relates to a door lock unit comprising a front plate and a body and which is adapted to be mounted with its body through a slot in a wall portion of a tubular element, the front plate of the unit being adapted to engage on an outer surface of said wall portion of the tubular member and to be attached to said wall portion by means of at least one screw that is inserted through an opening in said front plate.
    The door lock unit is in particular a mortise lock or a bolt catcher for a door lock. The word "door" is used herein to include all types of locking elements such as doors, with a full door panel, and gates. The door can be a hinged or sliding closing element. EP-B-2 186 974 describes a mortise lock that is arranged to be mounted on a tubular element of, for example, a garden gate, this mortise lock comprises a latch bolt that can be operated by means of two handles and a dead bolt that can be operated by means of a key-operated lock cylinder. lock body and a front plate mounted thereon by means of two screws To mount the lock on the tubular member, the lock body is inserted through a slot that is cut into a wall portion of the tubular member until the front plate engages the outer surface of Above and below the slot a hole has been made in the wall of the tubular element The tubular element is fixed by means of two self-tapping screws / bolts, which are inserted through openings in the front plate into the respective holes in the tubular element.
    A drawback of such a fastening system is that the holes for the self-tapping screws / bolts must be made at the right place in a side wall of the tubular element. This location must be determined fairly accurately since holes are made in the front and rear walls of the tubular element for the lock cylinder and the handles. Since the axis of the handles and the lock cylinder extend all the way through the tubular element, the position of the lock in the tubular element is determined by these elements. The holes for the self-tapping screws / bolts and for the lock cylinder and the handles must therefore be made in the right place relative to each other, which is not so easy since these holes are located on three different sides of the tubular element.
    A further disadvantage of the prior art fastening system of this lock is that the slot for the lock body and the holes for the handles and the lock cylinder must be made in the tubular element before it is coated with a protective coating so that this coating also remains intact at the location of this slot and holes. The tubular element is, for example, painted or galvanized to protect it from oxidation. However, even if the holes are made in the tubular element before it is coated, the protective layer is damaged at the level of the holes when the self-tapping screws / bolts are screwed into these holes in the tubular element.
    Another disadvantage of this known fastening system is that the thread of commercially available screws does not generally start immediately from the head of the screws. Since the front plate is clamped directly against the relatively thin wall of the tubular element and since the holes in the front plate must be countersunk to receive the heads of the screws / bolts, the front plate must therefore be rather thick. Such a thick front plate is not only more expensive but also less beautiful.
    A final drawback of this fastening system according to the current state of the art is that, due to the limited thickness of the wall of the tubular element, which in practice is only 1 to 1.5 mm, a strong fastening is not always possible be obtained. In particular if the screws are tightened too hard in the holes, the holes in the tubular element can even be damaged so that the required grip of the screws in the holes is lost. It is not possible to drill new holes in the tubular element, since the location of the holes for the screws is completely determined by the position of the holes for the handles and the lock cylinder. WO 2007/009998 describes a fastening system with screw and plug that makes it possible, for example, to mount a bolt catcher for a lock on a tubular element. This mounting system makes it possible to obtain a solid mounting. However, a disadvantage of this fastening system is that the holes for the screws have to be drilled in the right place again. Moreover, it is relatively expensive due to the milling operations that are required, in particular to produce the metal plug.
    To avoid having to drill holes in the side wall of the tubular element to attach the front plate to it, US 2012/0034021 proposes to estimate the latching tabs just behind the front plate when the lock is pushed into the tubular element , these tabs snap behind the wall portion of the tubular member that surrounds the slot through which the lock is inserted into the tubular member, so that the lock is automatically attached to the tubular member.
    A drawback of such an automatic fastening system is that the lock is not always firmly attached to the tubular element since the distance between the front plate and the snap-in tabs must generally be a little larger than the thickness of the wall of the tubular element, in order to allow the tabs to snap behind the wall of the tubular member. Moreover, the thickness of this wall can vary considerably considerably, in particular due to the coating material that is applied to the tubular element. This coating material can indeed run somewhat and accumulate, in particular in the form of droplets on the edges of the slot. If this happens, it may become problematic to mount the lock on the tubular member. At the level of such droplets, the wall of the tubular element would in fact be too thick to allow the snap-in tabs to snap behind this wall to secure the lock in the tubular element.
    A further disadvantage of this prior art automatic fastening system is that once the lock is clicked on the tubular element, it is no longer possible to remove it, for example when it is to be lubricated or when the piece is and must be will be replaced. FR 2 877 979 describes a lock that has the features of the preamble of claim 1. It is arranged to be mounted through a slot in a wall portion of a tubular element. It contains two clamp levers that can pivot between a retracted and a protruding position on the lock. The clamping levers are held in their retracted position by means of an elastic, such that the lock can be inserted through the slot in the tubular element. Each clamping lever is provided with a screw which is screwed through an opening in the front plate of the lock into a tap hole in the clamping lever. By tightening the screw when the lock is inserted into the slot, the clamping levers are pulled by the screws to their projecting position in which they contact the inner surface of the tubular element so as to cover the wall of the tubular element between the clamping lever between the front plate and clamp the clamping levers. Since the clamping levers are brought from their retracted position to their projecting position by means of the screws, the screws must already be screwed in there in the retracted position of the clamping levers. In this position, the screws also extend through the openings in the front plate. A drawback of the clamping device according to FR 2 877 979 is therefore that the openings in the front plate must be elongated and that the angle over which the clamping levers can be retracted is notwithstanding the elongated shape of the openings in the front plate. DE 1 428 516 describes a built-in lock that is clamped in a tubular element by means of a clamping lever. The clamping lever is clamped against the inner surface of the tubular element by means of a screw with a nut located behind the clamping lever. In this lock, the clamping lever is again pushed to its retracted position by means of a spring.
    It is an object of this invention to provide a new door lock unit that can be securely and reliably mounted in a slot in a tubular member, and this independently of the wall thickness of the tubular member. According to the invention, a front plate and a body are arranged to be mounted with its body through a slot in a wall portion of a tubular element, wherein the front plate of the U unit is adapted to engage on an outer surface. of said wall portion of the tubular member and to be mounted on said wall portion by means of at least one screw which is arranged through an opening in said front plate. The unit further comprises at least one clamp lever movably mounted on the body of the unit between a retracted position, in which the body of the unit can be inserted through said slot into the tubular element, and a protruding position, in which the clamp lever is adapted to to engage on an inner surface of said wall portion of the tubular member to clamp said wall portion between the front plate and the clamping lever, the clamping lever being provided with a tap hole axially aligned with said opening in the front plate in the projecting position of the clamping lever and which is adapted to receive said screw.
    To remedy the disadvantages associated with the lock described in FR 2 877 979, the door lock unit further comprises a spring for pressing the clamping lever to its projecting position.
    In this way, once the clamping lever has been inserted into the tubular element, it must only be released to be automatically brought to its projecting position by the spring such that the screw is inserted through the opening in the front plate and screwed into the tapping hole in the clamping lever. can become.
    Since the screw used to secure the unit in the tubular member is screwed into the tapping hole in the clamp lever, it can be tightened securely so that the wall of the tubular member is securely and reliably clamped between the face plate and the clamp lever. The operation of the clamping lever is hereby not influenced by the thickness of the wall of the tubular element. The clamping lever does not interfere with the insertion of the body of the unit into the tubular member since it is held in its retracted position when the unit is inserted into the tubular member.
    In a preferred embodiment of the door lock unit according to the invention, said clamp lever pivots about a pivot axis on the body of the unit between said retracted position and said projecting position, said pivot axis being substantially parallel to said front plate.
    In this embodiment, the clamping lever can simply pivot within the tubular member from its retracted to its protruding position until it engages the inner surface of the wall of the tubular member.
    The unit preferably includes a latch to hold the clamp lever in its retracted position.
    By simply operating this latch, the clamping lever is released and brought to its protruding position by the spring. The operation of the latch can be carried out, for example, through the hole for the bolt in the front plate.
    Alternatively, the lock may comprise a removable locking element which holds the clamping lever in its retracted position and which is in particular inserted through said opening in the front plate to engage the clamping lever.
    By simply removing this locking element, in particular by simply pulling this locking element through the opening in the front plate from the lock, the clamping lever is released and moves through the action of said spring in the tubular element until it extends behind the inner surface. of the wall of the tubular element. In this position the screw can be inserted into the unit through said opening in the front plate and screwed into the tapping hole in the clamping lever to firmly clamp the wall of the tubular element between the front plate of the unit and the clamping lever .

    The invention generally relates to a door lock unit comprising a front plate 1 and a body. The door lock unit may in particular be a mortise lock or a bolt catch for a door lock comprising a portion located in the support on which it is to be mounted. This support can be a fixed post or a top of a double door or gate. The term mortise lock is used to indicate that the body 2 of the lock, i.e. the lock body 2, must be inserted into a recess in a locking element.
    The invention will now first be explained in detail with reference to a mortise lock. The mortise lock of the present invention is adapted to be mounted with its lock body 2 through a slot 3 in a wall portion 4 of a tubular element 5. This tubular element 5 is a part of a gate, as shown for example in Figure 1, or of a door or any other type of hinged closing element.
    The locking mechanism of the lock can be of any type. It can comprise a latch bolt 6 which is operated by means of the handles 7, a night bolt 8 which is operated by means of a key, in particular via a lock cylinder 29 (for example a euro cylinder), or it can be a combination of a latch bolt 6 and a dead bolt 8 as in the embodiments shown in the drawings. Usually the latch bolt 6 and the night bolt 8 are slidably mounted in the lock to slide between a retracted and a protruding position. However, in the embodiments shown in the drawings, the dead bolt 8 is hook-shaped and pivots in the lock between its protruding and retracted positions. The lock shown in the drawings is in particular a lock described in EP 2 186 974. Further details about this lock can thus be found in this prior art patent integrated herein by reference.
    An essential difference between the lock shown in EP 2 186 974 and the lock in accordance with the present invention is the way in which the lock is mounted in the tubular member 5. The lock in accordance with the present invention comprises at least one clamp lever mounted such it is on the lock body 2 that it can move between a retracted position and a protruding position. In the embodiment shown in the drawings, the lock body 2 comprises a front cover plate 9 and a rear cover plate 10 which enclose the lock mechanism and which project above and below beyond this lock mechanism to provide space for the clamping levers, ie for a first clamping lever 11 at the upper end of the lock body 2 and a second clamping lever 12 at the lower end of the lock body 2. Both clamping levers 11, 12 are in the form of a plate which extends transversely between the projecting parts of the front and rear cover plates 9, 10 and which has two opposite projections at one end. In the embodiment shown in Figures 1 to 13, these projecting parts are received in holes 13 in the front and rear cover plates 9, 10 so that the two clamping levers 11, 12 can pivot about a first axis 14 and a second axis, respectively. 15 relative to the cover plates 9, 10. Both shafts 14, 15 are substantially parallel to the front plate 1. Moreover, they are preferably substantially perpendicular to the front and rear cover plates 9, 10 of the lock body 2.
    In the positions shown in Figures 1 to 4 and 10 to 11, the two clamping levers 11, 12 are held in a retracted position, in particular in a position in which they are located within the lock body 2, ie between the front and the rear cover plates 9, 10, so that the lock can easily be inserted with its lock body 2 through the slot 3 into the tubular element 5. Thus, in their retracted position, the clamping levers 11, 12 do not protrude from the lock body 2. The clamp levers 11, 12 can pivot about their axes 14, 15 from this retracted position to a projecting position in which they protrude from the lock body 2 to engage on the inner surface of the wall portion 4 of the tubular element 5 surrounding the slot 3 therein. This protruding position is shown in Figures 7 and 12. In this protruding position the clamping levers 11, 12 protrude above and below the lock body 2 for engaging the inner surface of the wall 4 of the tubular element 5. In this position, the wall 4 of the tubular element 5 can be clamped between the front plate 1 and the clamping levers 11, 12 by means of the screws 16, 17, so that the front plate 1 of the lock is fixed on the wall 4 of the tubular element 5. The screws 16, 17 are provided through openings 18 in the front plate 1 and are screwed into tapping holes 19 in the clamping levers 11, 12. To allow the screws 16, 17 to be screwed into the tapping holes 19 in the clamping levers 11, 12, in the protruding position of the clamping levers 11, 12, these tapping holes 19 are axially aligned with the openings 18 in the front plate 1.
    The lock preferably comprises a spring, in particular a torsion spring 20, for pressing the clamping levers 11, 12 to their projecting position. In this way the clamping levers 11, 12 only have to be kept in their retracted position when the lock body 2 is inserted into the tubular element 5. Once it is inserted, the clamping levers 11, 12 can be released so that the clamping levers 11, 12 are automatically brought to their projecting position by the spring 20.
    The clamping levers 11, 12 could, for example, be held in their retracted position by means of a rubber band arranged around the lock body 2. Such a rubber band could be pushed from the lock body 2 through one of the openings 18 in the front plate 1. or could be cut through these openings 18, which, however, is not that easy and might require suitable tools. In addition, the rubber band may break when the lock is inserted into the tubular member 5, especially if there is only a small gap between the lock body 2 and the lock 3 in the tubular member 5, or may break by itself when it is inserted during a is stored for a certain time, in particular in daylight, so that problems arise when the lock has to be inserted into the tubular element 5.
    To prevent such problems, the lock in the first embodiment, shown in Figs. 1 to 9, includes for each clamp lever 11, 12 a latch 21 adapted to hold the respective clamp lever 11, 12 in its retracted position. As can be seen in Figure 4, the latch 21 has a hook-shaped portion 22 which engages the clamping lever 11, 12 to hold it in its retracted position. In the embodiment shown in the drawings, the latch 21 is made of a flexible material so that it can be folded to release the clamping lever 11, 12. Alternatively, the latch 21 could also pivot on the lock body 2.
    To allow the clamping lever 11, 12 to be released when the lock body 2 is inserted into the tubular member 5, the latch 21 comprises a distal end 23 extending from the hook-shaped portion 22 of the latch 21. By simply pressing this pushing the distal end 23, the clamping lever 11, 12 is released and pivots automatically through the torsion spring 20 until it engages the inner surface of the wall 4 of the tubular member 5. As shown in Figure 6, the latch 21 can clamp lever 11, 12 can be operated with any thin, elongated tool 24, for example a screwdriver, a hex key or simply a nail or any other rod-shaped part, via the opening 18 provided for the screw 16, 17 in the front plate 1. After all, a passage 25 is provided in the lock between the opening 18 in the front plate 1 and the latch 21 to allow the latch 21 to be operated by means of an elongated tool 24 through this opening 18 to release the clamping lever 11, 12.
    In the second embodiment, which is shown in Figures 10 to 13, the lock for each of the clamping levers 11, 12 comprises a removable locking element 26 which holds the clamping levers 11, 12 in their retracted position. This removable locking element 26 is inserted through the opening 18 in the front plate 1 into the lock body 2 to engage the clamping lever 11, 12. The illustrated locking element 26 has the shape of a pin which is inserted into the opening 18 of the front plate 1 in such a way is that she gets stuck in it. More specifically, the locking element 26 comprises a compressible portion 27 which has an outer diameter slightly larger than the inner diameter of the opening 18 and which is adapted to be pushed through the opening 18 to secure the locking element 26 in the opening 18 The locking element 26 has a thicker part 28 protruding from the lock opposite the compressible part 27 and which can be easily grasped to remove the locking element 26 from the lock. As shown in Figure 12, when released, the clamping lever 11, 12 is rotated by the torsion spring 20 to engage the inner surface of the wall 4 of the tubular member 5. In this position, the screw 16, 17 can the clamping lever 11, 12 can be screwed, which is shown in Figure 13.
    An alternative embodiment of the clamping levers 11, 12, in which they are slidably mounted on the lock body 2, is shown in Figs. 15 to 17. In this embodiment, both clamping levers 11, 12 again have the shape of a plate which in the transverse direction between the protruding parts of the front and rear cover plates 9, 10 and which has two opposing protruding parts at one end. These protruding parts have a non-circular cross-section, in particular a square cross-section as can be seen in Figure 14, and are received in opposite slots 36 in the front and rear cover plates 9, 10 such that the clamping levers up and down can slide substantially in the longitudinal direction of the front plate 1. In the projecting positions of the clamping levers 11, 12 the projecting parts enter a widened part of the slots 36, so that they can pivot a little relative to the front plate 1. They can however, do not pivot away from the front plate 1 through the latches 21. The springs 20 for pushing the clamping levers 11, 12 in this embodiment to their projecting positions are compression springs instead of torsion springs.
    The latches 21 are adapted to hold the respective clamping lever 11, 12 in its retracted position. As can be seen in Figure 15, the latches 21 have a hook-shaped portion 22 which engages the clamping lever 11, 12 to hold it in its retracted position. The latches 21 are made of a flexible material so that they can be folded to release the clamping levers 11, 12. This can be done in the same manner as shown in Figure 6 with a tool 24 that can be inserted through the openings 18 in the front plate 1. When the latches 21 are pushed away from the clamping levers 11, 12, as shown in Figure 16, they are pushed by the compression springs 20 to their projecting positions. In these positions, the wall 4 of the tubular element 5 can be clamped between the front plate 1 and the clamping levers 11, 12 by means of screws 16, 17, so that the front plate 1 of the lock is fixed to the wall 4 of the tubular element 5. The screws 16, 17 are arranged through the openings 18 in the front plate 1 and are screwed into the tapping holes 19 in the clamping levers 11, 12. In order to allow the screws 16, 17 to be screwed into the tapping holes 19 in the clamping levers 11, 12, these tapping holes 19 are axially aligned in the projecting position of the clamping levers 11, 12 on the openings 18 in the front plate 1.
    As described above, the clamping levers 11, 12 can pivot into their extended positions in the widened portions of the slots 36, so that they can be easily pulled by the screws 16, 17 against the wall 4 of the tubular element 5. This tightened position is shown in Figure 17.
    In the embodiments shown in Figs. 1 to 17, the lock body 2 fits with some clearance at the top and / or bottom in the slot 3 in the tubular element. This play is made possible by the fact that the front plate 1 of the lock no longer has to be attached to the tubular elements by means of screws / bolts which have to be screwed into holes in the side wall 4 of the tubular element 5, but is fastened by clamping the wall 4 of the tubular element 5 between the clamping levers 11, 12 and the front plate 1. Because of the free space between the lock body 2 and the slot 3, the lock body 2 can thus be easily inserted into the tubular element 5. In addition, to mount the handles 7 and the lock cylinder 29 on the lock inserted into the tubular member 5, holes 30 and 31 have been made in the front and the rear of the tubular member 5. Furthermore, there are two smaller holes 32 arranged in the front and the rear of the tubular element 5 to allow the cover plates 33 of the lock to be attached to the tubular element by means of screws 34. By the play between the lock body 2 and the slot 3 in the tubular element, the slot 3 does not have to be arranged very accurately at the correct position with respect to the holes 30 - 32 in the front and the rear of the tubular element 5.
    In the embodiments shown in the drawings, the openings 18 for the screws 16, 17 are provided in the front plate 1 at the height of the lock body 2. This means that in the installed position of the lock the screws 16, 17 extend through the front plate 1 in the lock body 2. Since the slot 3 is even wider than the lock body 2, the screws 16, 17 extend through the slot 3 so that no separate holes have to be made in the wall 4 of the tubular element 5 for the screws 16, 17.
    To mount the lock on the tubular element 5, the lock is first inserted with its lock body 2 in the tubular element 5 through the slot 3. The clamping levers 11, 12 can then be released so that the lock is held in place by the clamping levers 11, 12, which are pressed against the wall 4 of the tubular element 5 by the torsion springs 20. Subsequently, the handles 7, lock cylinder 29 and cover plates 33 can be mounted on the front and rear sides of the tubular element 5. During this assembly, the lock can still be moved up or down a little in the slot 3 to correctly lock the lock body. to be aligned with respect to the holes 30 and 31 for the handles 7 and the lock cylinder 29 in the tubular element 5. Finally, the lock can be securely fixed by screwing the screws 16, 17 into the tapping holes 19 in the clamping levers 11, 12 screws.
    Due to the fact that the screws 16, 17 can be screwed tightly into the clamping levers 11, 12, these screws can also be used to attach additional accessories to the tubular element 5. As shown in Figs. 7 to 9, one of these screws, namely the lower screw 17, for example used to attach an additional safety member 35, which is in the form of a mushroom, to the tubular element 5. As described in detail in EP-B-1 600 584, which is integrated herein is by reference, such a mushroom-shaped safety member 35 can hook behind a portion of the bolt catcher when the door or gate is closed, so that the shots of the lock cannot be forced out of the bolt catcher by forcing the lock and the bolt catcher away from each other, for example by means of a crowbar. This of course requires a reliable and firm attachment of the safety member 35 to the tubular member 5.
    The fastening systems with the clamping levers 11, 12 that are held in their retracted positions by means of the latches 21 or the removable locking elements 26 can also be applied to a bolt catch for a door lock which, as shown in Fig. 18, again comprises a front plate 1 and a bolt catcher body 37. Like the lock body 2, the bolt catcher body 37 extends in the assembled position of the bolt catcher through a slot 3 in a tubular member 5. In the embodiment shown in Figs. 18 to 21, the same fastening system becomes used as in the embodiment of the lock shown in Figures 1 to 9. This fastening system comprises the two clamping levers 11, 12 pivoting about the shafts 14, 15 on the bolt catcher body 37 and which are held in their retracted position by the latches 21 as shown in Figure 19. T away through the latches 21 through the openings 18 in the face plate 1 After pressing the clamping levers 11, 12, the clamping levers 11, 12 are released and they are rotated by the torsion springs 20 against the inner surface of the wall portion 4 of the tubular element 5. This position is shown in Figure 20. The bolt catcher can then be fixed by means of the screws 16, 17 which are screwed through the openings 18 in the front plate 1 into the clamping levers 11, 12, so that the wall 4 of the tubular element 5 is clamped between the front plate 1 and the clamping levers 11, 12 ( see figure 21).
    It will be clear to a person skilled in the art that, within the scope of protection as defined in the appended claims, further changes can be made to the locks described above.
    In particular, one of the two clamping levers 11, 12 can be omitted, for example the lower one, and be replaced by a gap between the front plate 1 and the body 2 of the unit, as illustrated for example in Figure 3 of US 2012/0034021, such that the unit can first be slid with this gap at the lower edge of the slot 3 over the side wall 4 of the tubular element 5, after which the body of the unit can be rotated around this edge of the slot 3 in the tubular element 5 .
