Definitions

  • the present invention relates to a locking mechanism for a window or door.
  • the invention is particularly aimed at a burglar-resistant locking mechanism for a sliding door, although the invention is not limited to this.
  • Burglar-resistant locking mechanisms are already known for locking the movable leaf of a window or door in the closed position with respect to the fixed frame of the window or door by means of a built-in lock.
  • the locking pins in themselves are not strong enough to prevent a break-in, but through the use of a multiple of such locking pins a break-in can be seriously slowed down, such that burglars generally abandon their break-in attempt early so as not to give the emergency services the time to catch them in the act.
  • a first disadvantage is that such known locking mechanisms are generally made to measure and are composed of many components, such that they are relatively expensive and the mounting in a window or door takes a lot of time.
  • Another type of locking mechanism is known whereby two solid rods are built into a vertical post of the movable leaf, whereby the rods can be moved axially by means of a lock between a retracted position in the post and a locked position whereby an end of the rods is inserted in corresponding holes, respectively in the top and bottom horizontal profile of the fixed frame of the window or door. In this way an undesired opening of the window or door is obstructed.
  • Such a locking mechanism can be cracked relatively easily and quickly, such that such a type of locking mechanism generally does not satisfy the applicable anti-burglar standards, such that for example an RC2 break-in class according to the EN 1627 standard of 2011 is difficult to achieve.
  • Such locking mechanisms are known that can achieve an RC2 break-in class, but these locking mechanisms have the disadvantage that they can only be applied to doors or windows with profiles specially developed for this purpose. However, the door or window constructors must have extra specific profiles in stock for this purpose.
  • an extra metal slat is also provided that is screwed onto the frame of the door or window with extra strong screws to reduce the distance between the movable leaf and the frame in order to reduce the risk of a lever or similar being squeezed in between.
  • This of course means an extra cost in extra material and components.
  • the purpose of the present invention is to provide a solution to one or more of the aforementioned and other disadvantages with a cost-efficient design of a locking mechanism that is easy to install, highly burglar resistant and which is no more expensive than a conventional non-burglar-resistant locking mechanism, and which in its most preferred embodiment can satisfy the strict RC2 resistance class according to the EN 1627 standard of 2011 or 2-star class according to NEN 5089 of 2009.
  • the invention concerns a locking mechanism for a window or door with a movable leaf, affixed in a fixed frame and which is to be operated by a lock with at least one operating arm that slides in and out, whereby the locking mechanism comprises a locking rod, that is axially movable with the operating arm, with a locking pin at its end to be able to lock the movable leaf with respect to the fixed frame in the closed position of the window or door, wherein the locking rod is composed of said metal locking pin that is axially movably affixed in a hollow guide profile, and which is connected or can be connected to an aforementioned operating arm of the lock by means of a connecting element that is elastically compressible in the axial direction and which is intended to be able to move the locking pin axially between a locked position and an unlocked position by operating the lock, whereby the connecting element is constructed as a flexible rod made of plastic or such.
  • An advantage of such a locking mechanism according to the invention is that it does not need to be built in, and that after adjusting the length of the guide profile and the locking rod, it is easily mounted against the movable leaf.
  • the length can easily be steplessly adapted to the dimensions of any door or window chosen at random. It can be done with one single saw cut when the locking rod is mounted in the guide profile, whereby they can then be sawn to size together.
  • Another advantage is that the mechanism is composed of few components, such that storage costs and logistical costs can be kept lower than with known locking mechanisms with many more components.
  • An advantage of an elastic connecting element constructed as a flexible plastic rod or another material with comparable features with respect to flexibility and elasticity is that the locking rods of a mounted window or a mounted door with a locking mechanism according to the invention can be replaced without much difficulty and dismantling work. Indeed, it is sufficient for the lock to be demounted to remove and put back the flexible rods via the aforementioned cutaway for the lock in the guide profile.
  • a locking rod with a section of plastic or other comparable material is generally cheaper than a completely metal rod of hardened metal and is also easier to make to size.
  • the locking mechanism is constructed such that the flexible rod of plastic or such has the freedom to bend or buckle elastically and/or upset elastically, at least locally, when compressed in the mounted situation in the guide profile, whereby in other words when upset due to compression the material of the rod has the possibility to expand sideways.
  • the elastic bending and/or upsetting thereby increases the elastic absorption capacity to absorb the forces exerted during a break-in, which further impedes a break-in.
  • two locking pins are used, one at the top and one at the bottom of the movable leaf, whereby the locking pins are each connected to the lock by means of an elastic connecting element in a guide profile.
  • the same guide profile is provided for both locking pins and guide profile is provided with a cutaway for the lock in the transverse direction, whereby the cutaway divides the guide profile into two branches, each with a locking pin and a connecting element.
  • An advantage of two locking pins, each with an elastic connecting element, is that after each attempt to force the locking pin out of the frame, the locking pin shoots back and pulls back into the frame.
  • This provides the advantage that the burglar must concentrate on the two locking pins at the same time, which is in contrast to the known locking systems with two locking rods whereby the burglar can tackle the pins one by one separately. It goes without saying that this makes breaking in more difficult and takes more time, especially in the case of a door where the locking pins are located far apart.
  • every conventional door or window that is composed of conventional profiles can be converted into a door or window that satisfies the RC2 break-in class.
  • the guide profile is preferably made of aluminium or another metal to protect the rod of plastic or such against break-in attempts.
  • Cutaways can be provided on the inside wall of the hollow guide profile that enable a slight bending of the connecting element during a break-in such that such bending can contribute to the absorption of the forces that are exerted on the locking pin by the burglar.
  • the aforementioned rod of plastic or such is hollow, which as a result provides the advantage that an easy connection to the locking pin is possible, which can be provided with a screw to this end with which the locking pin can be screwed into the connecting element, and that moreover as a result space is also provided to at least partially elastically absorb the forces that occur during a break-in by the material of the hollow rod upsetting inwards.
  • a coupling piece can be provided to couple the connecting element to the lock, whereby the coupling piece can also be provided with a screw with which the coupling piece can be screwed into the hollow rod.
  • a small clearance is preferably left between the inside wall of the hollow guide profile and the outer periphery of the connecting element that is sufficient to enable a bending and/or expansion of the connecting element outwards to be able to elastically absorb the forces exerted on the connecting element during a break-in.
  • This clearance can be all around or only local, for example in the form of cutaways that are provided along the periphery of the connecting element.
  • screws can preferably be mounted that are screwed through passages in the guide profile into the post concerned, whereby the head of the screws is countersunk in a deepened seat that is concealed behind the locking rod.
  • the locking mechanism according to the invention is provided with spacers that are mounted between the guide profile and the post of the movable leaf, whereby the spacers have a thickness that is adapted to the form and type of the post profile on which the locking mechanism must be mounted, so that the guide profile can be mounted on doors and windows of a number of suppliers, each with their own specific profiles.
  • the position of the guide profile can also easily be adjusted to the built-in depth of a certain lock in the post.
  • these spacers are fastened to the profile in a clipable way so that they can be temporarily positioned easily and quickly and they thus do not have to be kept in place while screwing the guide profile on the leaf of the door or window and an extra pair of hands is thus not required for this purpose.
  • the locking mechanism is provided with a metal locking plate with a passage for an aforementioned locking pin and with means to fasten the locking plate to the fixed frame, so that the passage for the locking pin that is made directly in the fixed frame by drilling or similar, is finished more professionally and is also strengthened.
  • an extra intermediate plate of elastically compressible material is provided that is intended to be mounted between the aforementioned locking plate and the frame, and which ensures that in the event of a break in, the locking system can be deformed but cannot break, such that it is difficult to get the locking pin out of the locking plate.
  • Such a locking plate with intermediate plate is preferably mounted in both the top and the bottom profile of the frame.
  • the invention also relates to fittings for a locking mechanism for a door or window as described above, that consists of a set of one or more of the following components or a combination:
  • Such fittings have the advantage that they are adaptable to many types of doors and windows with different profiles that make up these doors and windows.
  • the invention also relates to a door or window provided with a locking mechanism according to the invention.
  • the sliding door 1, that is shown in figure 1 by way of an example, is made up of a fixed frame 2 and a movable leaf 3 therein, which in this case can be locked in the closed position as shown by operating a cylinder lock 4.
  • a locking mechanism 5 for the locking of the sliding door 1 use is made of a locking mechanism 5 according to the invention, as shown in figure 2 , and which is built into the sliding door 1, as shown in figure 3 , between a vertical post 6 of the fixed frame 2 and a vertical post 7 of the leaf 3, such that in the locked state of the sliding door the locking mechanism 5 cannot be accessed by a burglar or similar without force.
  • the locking mechanism is provided with a conventional lock 8, which, as is known and as shown in figure 5 , is provided with two operating arms 9 that can be operated by means of the aforementioned cylinder lock to be able to be moved towards or away from one another in a vertical direction in order to lock or unlock the sliding door.
  • the locking mechanism is further provided with two locking pins 10, respectively a bottom and top locking pin of stainless steel or another hardened metal or similar, that are each connected to the aforementioned operating arms 9 of the lock 8 by means of a connecting element 11 and a coupling piece 12, with it all being composed as two locking rods 13, which in this case have a constant diameter over their entire length.
  • the coupling piece 12 is provided at the ends with a transverse pin 14 that fits in a transverse opening 15 of an operating arm 9 for coupling to this last-mentioned.
  • the connecting element 11 is elastically compressible in a certain sense in the axial direction of the locking rod 13, preferably over a distance of approximately 10 mm per running metre of the connecting element 11 upon the application of a force of 3000 N, and to this end is preferably made of plastic for example, for example PVC that has undergone a heat treatment to obtain a dimensional stability in the rest state within a temperature range from -20°C to 60°C.
  • the locking pins 10 and the coupling pieces 12 can be provided with an axially extending screw 16 at an end with which it can be screwed into the hollow rod in line with the connecting element 11.
  • the locking mechanism 5 is further provided with a hollow tubular guide profile 17, as shown in figure 4 , which is provided with a cutaway 18 in the transverse direction for the lock 8 with its operating arms 9, whereby the cutaway 18 divides the guide profile 17 into two branches that are each provided for guiding an aforementioned locking rod 13 in the axial direction X-X'.
  • the passages 19 in the side 22 that are turned away from the post 7 have a diameter A that approximately corresponds to the diameter of the head of the screws 21, while the passages 20 on the opposite side 23 present a smaller diameter B that approximately corresponds to the diameter of the shank of the screws 21.
  • the passages 20 are provided with a concealed seat 24 along the inside wall of the guide profile 17 for the head of the aforementioned screws 21, so that in the mounted state of the locking mechanism 5, the head of the screws 21 is concealed in an inaccessible manner behind the locking rod 13 in the guide profile 17, as shown in figure 9 .
  • spacers 25 can be provided with an adapted thickness C.
  • the spacers 25 can either be made a suitable thickness upon assembly, or alternatively a choice can be made from a series of spacers of different thicknesses.
  • Figures 10, 11 and 12 illustrate different possible mountings of the guide profile 17 against posts of a different form or type, with a spacer 25 of a different thickness in the three cases, or in the case of figure 11 , without a spacer 25.
  • the spacers 25 are made as a ring or bush that determines the thickness C and which is equipped with two elastic bent arms 27 with which the spacers 27 can be fastened against the guide profile 17 by clipping the arms 27 in the grooves 28 provided to this end, in the side 23 of the guide profile 17.
  • locking rods 13 are incorporated in the guide profile 17 with a certain clearance, whereby cutaways 30 are provided in the inside wall 29 of the hollow guide profile 17 that define a local clearance between the locking rods 13 and the guide profile 17 along the periphery of the locking rods 13 so that space is provided to the connecting element 11 to bend and expand somewhat.
  • the aforementioned cutaways 30 extend along the aforementioned periphery over two sectors that are turned with respect to one another by approximately a quarter circle, as shown in figure 6 , although other configurations are not excluded, for example by cutaways in the connecting element 11 itself instead of in or in combination with cutaways in the guide profile 17 or without local cutaways but with a clearance over the entire periphery due to a difference between the inside diameter of the guide profile 17 and the outside diameter of the connecting element 11.
  • the locking pins 10 are further guided in the axial direction by holders 31 that are fastened perpendicularly to the guide profile 17 against the underside and top respectively of the leaf, for example as shown in figures 15 to 17 by means of bolts 32 that are screwed transversely through the horizontal profiles 33 of the frame of the leaf 3 into metal reinforcing plates 34 on the inside of the frame, or alternatively, by means of screws, which, if possible, can be screwed directly in the horizontal profiles 33 without the intervention of a reinforcing plate 34.
  • the holders 31 are provided with a passage 35 for the locking pin 10 that is mounted in line with the guide profile 17 so that the locking pins 10 are not only held in their place by the guide profile 17, but also by the holders, so that when a burglar succeeds in detaching the guide profile 17, the locking pins 10 are still kept in their place. This will substantially slow down the break-in attempt as he will now have to be able to force the holders 31 to achieve success.
  • the thickness D of the holders is chosen according to the dimensions and form of the profiles of the frame 2 and the leaf 3 and are adapted such that they limit the vertical freedom of movement of the leaf 3 in the fixed frame, so that it is impossible for a burglar to lift the leaf 3 out of the fixed frame 2 without extra arrangements having to be made for this.
  • the thickness D of the holders is preferably such that there is little clearance in the vertical direction between the holder 31 and the frame 2.
  • the holders 31 are preferably easily made a suitable thickness. Alternatively a series of holders 31 with different thicknesses D can be provided from which a holder 31 with a suitable thickness D can be chosen.
  • the ends of the guide profile 17 fit closely against the holders 31 in order not to give a burglar any opportunity to squeeze a long screwdriver or other lever in between. To this end it is necessary to make the guide profile 17 a suitable length.
  • an accessory 43 can be used, as illustrated in figure 19 , that keeps the connecting element 11 in the guide profile 17 in place during sawing.
  • the holders 31 can be provided with dowel pins 44 with which they can be correctly aligned in a transverse direction with respect to the guide profile 17, to which end this guide profile 17 is provided with corresponding slots 45, as best illustrated in figure 6 .
  • openings 36 are provided in the bottom and top horizontal profile 37 of the fixed frame 2 that are in line with the locking pins 10 when the leaf 3 is slid to its closed position in the frame 2.
  • a locking plate 38 can be used that is screwed by means of screws 40 against the frame 2, preferably with an interjacent intermediate plate 41 of elastically compressible material.
  • a connecting element 11 must be such that it is only compressible in the axial direction X-X' to a limited extent, without excessive forces, over a distance that may not be greater than the length E of the locking pin with which it protrudes in the frame 2 in the locked state. For the rest this applies just as much to the construction of the connecting element 11 in the form of a plastic rod.
  • the locking mechanism 5 in the form of fittings with separate components and in the mounted form in a door or window belong to the invention. It goes without saying that a locking mechanism in the form of fittings does not necessarily contain all components described above, such as a lock 8, spacers 25, screws and bolts and similar.
  • the locking mechanism according to the invention is not limited to sliding doors but can also be used in other types of doors, for example double revolving doors or similar.
  • the present invention is by no means limited to the embodiment described as an example shown in the drawings, but a locking mechanism according to the invention can be realised in all kinds of forms and dimensions without departing from the scope of the invention as defined by the appended claims.
