Description

[0001] The invention relates to a lock for a door or window of a building having the features of the preamble of claim 1.

[0002] From FR 2 753 225 A1, a door lock with a screwed-on lock cover is known. The door lock has a lock housing that is manufactured as a single piece. It has a lock base and side plates with a faceplate that are attached to it in one piece. The lock base has permanently riveted threaded bolts that serve to fasten the lock cover. A disadvantage of this design is that any modifications to the door lock require a complete redesign of the lock housing.

[0003] WO 03 / 033 845 A1 discloses a door lock with a screwed-together lock housing. The lock housing is constructed in two parts: a base and a screwed-together top. Threaded inserts in the form of nuts with internal threads are arranged in the base, corresponding to screws in the top. Both the base and top have beveled side plates that, when the lock is assembled, rest against each other and define the lock's thickness. This is also a relatively rigid lock design, meaning that any modifications to the lock necessitate a redesign of the lock housing.

[0004] From CN 2 06 279 880 U, a door lock with a lock housing is known, which has a lock base, a lock top, as well as side walls and a faceplate. The lock has several spacers, with the lock base and the lock top being screwed to the spacers.

[0005] The object of the present invention is to provide a lock that is mechanically robust, easy to install, and highly flexible. In particular, the lock should be upgradeable or expandable without requiring a redesign of the lock housing. Preferably, the lock should be easy to maintain and thus have low maintenance and repair costs.

[0006] This problem is solved according to the invention by a lock having the features of claim 1.

[0007] According to the invention, a lock for a door or window of a building is proposed, comprising a lock housing with a lock base, a lock top, side walls, and a faceplate, with a bolt element movably mounted in the lock housing for locking or unlocking a leaf of a door or window. A key feature is that at least two spacers, or several spacers, are arranged interchangeably in the lock housing, and that the lock base and / or the lock top are screwed to the spacers.

[0008] Advantageously, a flexible lock design can be achieved by exchanging the spacers. For example, in mechanically demanding applications, several spacers can be used to create a particularly robust and durable lock. Furthermore, by varying the length of the spacers, the lock thickness and thus the volume of the lock housing can be adjusted.

[0009] In particular, screwing the lock base and the lock top together has the advantage that the lock can be installed easily. Additional joining techniques, such as riveting, soldering, or bending of side parts, or the provision of connecting pins between the lock top and the lock base, are not necessary with the lock according to the invention, thus saving manufacturing costs.

[0010] The lock for a door or window of a building can, in particular, be a mortise lock. The building's door can, for example, be a single-hinged swing door. The building's door can be designed as a single-leaf door or as a double-leaf door, with the double-leaf door preferably having an active leaf and a fixed leaf, or an active leaf and a passive leaf.

[0011] The lock can be designed as a mortise lock, in particular as an active wing lock for a single-leaf door, or for a single-leaf door.

[0012] The lock can also be designed as a mortise lock for a passive wing, preferably as a passive wing lock for a fixed wing.

[0013] Preferably, the term "lock housing" refers to a housing for containing lock components and / or locking elements. The lock housing can be made of a metal, for example, sheet steel or aluminum.

[0014] Preferably, the term "locking elements" refers to a lock bolt and / or a lock latch and / or a locking bar and / or a latch slide and / or a locking bolt slide.

[0015] In particular, the spacers can be made of the same material as the lock housing itself. Alternatively, the spacers can also be made of a different material, preferably a metal or steel.

[0016] The spacers of a lock can each have the same cross-section. It is also conceivable that the spacers of a lock are designed with different cross-sections to meet different mechanical requirements. For example, the cross-section of the spacers can be increased to achieve higher mechanical resistance.

[0017] In a preferred embodiment, the side walls of the lock housing are designed to be separate, i.e., removable. The side walls of the lock housing form its narrow sides. That is, the side walls form the narrow side at the top of the lock, the narrow side at the bottom of the lock, and the rear of the lock housing opposite the faceplate. Because the side walls are separate from the lock base and top, the thickness of the lock housing can be varied by simply changing the dimensions of the side walls and the spacers.

[0018] Preferably, the lock base can be designed as a flat plate or a planar plate. Similarly, the lock top can be designed as a flat plate or a planar plate. This has the advantage that, for example, the lock base can be manufactured as a simple stamped part. The lock top can also be manufactured as a simple stamped part. Since no further processing steps, in particular no bending, riveting, or soldering of connecting parts, are necessary, the manufacture of the lock is correspondingly simplified.

[0019] In particular, it can be provided that the at least two spacers, or the multiple spacers, each have a thread for the lock base and a thread for the lock top. This advantageously makes it possible to form a connection to both the lock base and the lock top using a single spacer.

[0020] Preferably, the thread of the spacers can be designed as an internal thread.

[0021] Advantageously, it can be provided that in at least one of the spacers, or in several of the spacers, or in all spacers, the thread for the lock base is aligned with the thread for the lock top.

[0022] For the sake of simplicity, it can be provided that in at least one, or in several, or in all of the spacers, the thread is formed as a threaded hole passing through the spacer. This allows for simple manufacturing of the spacers, as the through-hole can be formed, so to speak, in a single step as a drilled hole followed by a thread.

[0023] To increase the mechanical stability of the lock housing, the spacers can be designed to rest directly against the lock base and top. Increasing the cross-section of the spacers can enlarge the contact area on the lock base and top, thereby improving the mechanical strength of the lock housing.

[0024] Advantageously, it can be provided that at least one of the spacers, or several of the spacers, or all of the spacers, are detachably mounted to the bottom and top of the lock, in particular by screws.

[0025] Advantageously, the lock housing can be designed to be assembled exclusively with screws. Specifically, the lock base and / or top can be attached to the spacers solely by screwing them together. This offers the advantage of simple and flexible manufacturing, which is also cost-effective thanks to the straightforward screw connection. By loosening the screws, the interior of the lock housing is easily accessible, facilitating simple maintenance and repair of the lock.

[0026] In particular, no rivets, soldering, or other connections are necessary for mounting the lock housing. A significant advantage is that no mortise pins are required between the lock top and bottom, as is otherwise common in lock construction. These mortise pins are typically used for the mechanical stabilization of lock housings but are relatively cumbersome to handle during assembly and maintenance.

[0027] Further improvements to the mechanical stability and flexibility of the lock housing can be achieved by providing at least one, or several, of the spacers with a threaded hole on one of their sides for screwing a side panel or faceplate to it. This allows for a three-point fastening using a single spacer: to the top of the lock, to the base, and to the faceplate or side panel. This results in a particularly rigid lock housing construction. Furthermore, the number of parts required for the lock assembly can be reduced, as a single spacer provides three-point fastening, i.e., a mechanical connection of three components.

[0028] In an advantageous embodiment, the faceplate can be detachably screwed to the lock housing via one or more spacers, preferably exclusively by screwing it to the lock housing via one or more spacers. Surprisingly, it has been found that this method also allows the faceplate to be attached to the lock housing simply and with high mechanical stability. This further increases the flexibility of the lock, as the faceplate can be easily replaced, allowing, for example, the use of faceplates of different lengths.

[0029] In an advantageous embodiment, at least one, or several, of the spacers may have a groove on one of its side faces for inserting a side panel. This further simplifies the manufacture of the lock, as the side panels can simply be inserted between two opposing spacers, thus eliminating the need for separate fastening or fixing of the side panels. The groove may extend in a straight line along the side face of the spacer from the top of the lock to the bottom.

[0030] For flexible expandability of the lock, the lock housing is designed to accommodate one or more functional modules. These modules include one or more spacers for securing the lock base and / or top. This allows, for example, the construction of a simple mechanical lock with few functional components by using multiple spacers in the lock housing for stabilization. If the lock is to be upgraded with additional functional components, some of the spacers can be removed and replaced with functional modules. A key advantage is that the basic assembly of the lock remains unchanged. In particular, the mounting points remain the same, so the lock can still be easily assembled and manufactured using simple screws.It may be provided that one of the functional assemblies is designed as a spring module, or as a trap module, or as a trap-slide module, or as a drive module, or as a sensor module.

[0031] It is intended that a spacer is integrated into the functional assembly, or into several functional assemblies. Specifically, the functional assembly can be formed integrally with the spacer(s), or the multiple functional assemblies can each be formed integrally with the spacer(s). By integrating the spacers into a functional assembly, the functional assembly is sufficiently secured and stabilized within the lock by the spacers themselves, and simultaneously, using the same screws, the lock top or bottom is fastened. This means that separate fasteners for fixing such functional assemblies are unnecessary. This also simplifies assembly.

[0032] The inventive concept also extends to a method for upgrading or converting a lock, comprising the following steps: Providing a lock according to one of the embodiments described herein, removing the lock top and / or bottom by loosening the screws, removing one or more spacers from the lock housing, inserting a functional assembly into the lock housing in place of the removed spacers, and attaching the lock top and / or bottom by screwing it on.

[0033] A particular advantage is that the lock can be upgraded or retrofitted not only at the factory, but also in the field, i.e., on locks already installed in buildings. This allows for a simple retrofit of locks or entire locking systems.

[0034] In particular, it may be provided that one or more spacers can be removed from the lock housing by loosening screws, especially in order to insert a functional assembly at that location.

[0035] Preferably, this can be done by securing the functional assembly inserted into the lock housing with the previously loosened screws of the spacers.

[0036] The lock according to the invention can be used as a standalone solution for doors or windows in buildings. Alternatively, the lock can also be combined with a large number of corresponding locks in a master key system in large buildings.

[0037] The figures show advantageous embodiments of the lock according to the invention, which are described below. Fig. 1 shows an example of a locking device with a lock according to the invention; Fig. 2 shows a schematic view of a lock according to the invention as an active wing lock; Fig. 3 shows a schematic view of a lock according to the invention as a passive wing lock; Fig. 3a shows a detailed enlargement in the corner area of ​​the lock.

[0038] The figures show exemplary embodiments of the lock 2, 3 according to the invention. These are not to be understood as limiting. In the figures, components that function identically are designated with the same reference symbols. A person skilled in the art can, using their practical skills, combine the different embodiments shown within the scope of protection defined by the claims without departing from the inventive concept.

[0039] The Fig. 1 Figure 1 shows a schematic representation of a locking device 1 with the lock 2, 3 according to the invention on a double-leaf door 11. The double-leaf door 11 has a fixed leaf 14 and an active leaf 15. The fixed leaf 14 is pivotally mounted on a door frame 12 of the double-leaf door 11 via hinges 131, 132. Likewise, the active leaf 15 is pivotally mounted on the door frame 12 of the double-leaf door 11 via hinges 133, 134.

[0040] The active leaf 15 has a panic lock 2 as a lock 2 according to the invention, which can be operated via a door handle 21. The panic lock 2 is designed as a self-locking panic lock 2 and has a self-extending bolt 24 and a latch. The inactive leaf 14 has a passive leaf lock 3 or multi-point locking system 3 as a lock 3 according to the invention. The multi-point locking system 3 has an upper multi-point locking bar 33 and a lower multi-point locking bar 34.

[0041] In the presentation of the Fig. 1 The multi-point locking system 3 is locked, meaning that the two locking bolts 33 and 34 are extended and lock the fixed leaf 14 to the door frame 12 and the floor. The multi-point locking system 3 can be manually unlocked via a lock follower 31. Furthermore, the multi-point locking system 3 has a motor by means of which it can be unlocked automatically. The motor's connection cable 16 is routed through the fixed leaf 14 and over the door frame 12 by means of a flexible cable transition 17. The multi-point locking system 3 has a latch receptacle and a bolt receptacle into which the locking elements 24 of the panic lock 2, i.e., the latch and the bolt 24, can engage. The panic lock 2 can be unlocked by means of the multi-point locking system 3 via the latch slide and bolt slide, respectively.that when the locking bolt 3 is unlocked, the panic lock 2 is unlocked first, allowing the active leaf 15 to be opened, while the inactive leaf 14 remains locked via the locking bolts 33, 34. Only when the locking bolt 3 is fully unlocked can the inactive leaf 14 then be opened.

[0042] The Fig. 2 Figure 1 shows a lock according to the invention designed as an active-wing lock 2, with the lock cover removed for clarity. The active-wing lock 2 has a lock housing 22 with a faceplate 23. The lock housing 22 comprises a lock base 27 and a lock cover (not shown in the drawing), which has been removed to illustrate the internal workings of the lock. Furthermore, the lock housing 22 includes several side walls on its narrow sides, i.e., narrow side walls on the top 222, the back 221, and the bottom 223. The side walls 221, 222, and 223 are dimensioned such that the lock housing is completely enclosed. The side walls 221, 222, and 223 are each designed as separate side walls and can be individually removed from or mounted on the lock housing 22. The faceplate 23 closes the lock housing 22 at the front.towards the door rebate and has recesses through which the control elements of the active wing lock 2 pass.

[0043] The depicted active wing lock 2 is designed as a self-locking panic lock 2. It has a locking bolt 24 that can be engaged or disengaged from the lock housing in a position that is closed back into the lock housing. Fig. 2 The lock 2 is shown to be movable. In addition to the locking bolt 24 as a locking element, the lock 2 also has a latch 25 as a locking element, which is designed as a tilt latch.

[0044] To control the locking of the lock 2, an auxiliary latch 25a is arranged below the main latch 25. The auxiliary latch 25a detects when a door leaf is in the closed position, and as soon as the lock or door is in the closed position, the bolt 24 is moved into its locked position by means of a spring assembly. To unlock the lock 2, it can be opened, for example, by turning a door handle using the cam 26 or by using a key with the cylinder.

[0045] Spacers 4 are provided within the lock housing 22. The spacers 4 connect the components of the lock housing, namely the faceplate 23, the lock base 27, the lock top, and / or the side walls 221, 222, 223 of the lock 2. The spacers 4 are interchangeable. They can also be replaced by corresponding functional assemblies. For example, in the upper area of ​​the lock housing, a spacer can be provided instead of the latch 25 to create a lock without a latch.

[0046] In the Fig. 3 A lock according to the invention is shown as a passive wing lock 3 or a drive bolt lock 3. Fig. 3 Figure 1 shows only the lock housing 32 of the passive wing lock 3. The lock components included within the lock housing 32 are shown in the Fig. 4 schematically represented.

[0047] The lock housing 32 has a lock base 36 and a lock top 37. The lock base 36 is connected to the lock top 37 via spacers 4. Each spacer 4 has a through threaded hole for screwing the lock base and lock top together. The faceplate 35 is located on the front of the lock housing 32 and is also connected to the lock base 36 and lock top 37 by means of spacers 4. The side walls of the lock housing 32, comprising the top, back, and bottom, are in the Fig. 3 Not shown for clarity. The spacers 4 each have a groove 41 into which the side walls or the back wall can be inserted, so that they are automatically held in place by the spacers 4. The side walls of the lock housing 43 are positively locked in the grooves 41 and no longer need to be attached separately.

[0048] In the Fig. 3a An enlarged view of the spacer in the upper corner of the lock housing 32 is shown. The spacer 4 is arranged between the lock base and the lock top 37, has a threaded hole for fastening the lock base or the lock top by means of a screw, and a groove 41 on each side surface for inserting a side wall of the housing.

[0049] The Fig. 4 Figure 1 shows a schematic representation of the passive leaf lock as a multi-point locking system. It has an upper multi-point locking bar 33 and a lower multi-point locking bar 34. The multi-point locking system 3 can be operated either manually via a lock follower 31 or by motor via a drive module 38 or motor module 38. When unlocking, the upper locking bar 33 and the lower locking bar are retracted into the lock housing 32, either by motor or manually. Additionally, the locking elements 24, 25 of an active leaf lock 2 are pushed back by means of a latch slide or bolt slide 39, thereby unlocking the door 11.

[0050] In the Fig. 4 It is evident that the strike plate 35 is also screwed to the lock base 36 or the removed lock cover 37 via the spacers 4. In the Fig. 5 The bolt lock 3 is shown without components of the lock mechanism to illustrate the mechanical structure of the lock housing. It can be seen that three spacers 4 are arranged in the area of ​​the faceplate 35. These three spacers 4 are each screwed to the lock base 36 and also have a horizontal screw connection to the faceplate 35. This can also be seen, for example, in the perspective view of the Fig. 6 evident. In the Fig. 6a The connection via the middle spacer 4 is shown enlarged.

[0051] Around its outer edge, the lock housing 32 has several spacers 4, each with a groove 41, for holding a side part or side wall of the lock housing. Fig. 4a This is illustrated in detail using the upper part of the lock 321 as an example. A section of the upper side wall 321 is inserted between two spacers 4 in such a way that it is positively locked between the two grooves 41. The in Fig. 4a The spacer component shown in the direction of the faceplate 35 thus has several functions. Firstly, it serves to screw the lock base and lock top together, secondly, to hold the side panel 321, and also to screw the faceplate 35 in place. Therefore, the spacers 4 combine several holding functions in a single component. Not only are the lock base and lock top held together, but the side panels and / or the faceplate of the lock housing are also held in place by the spacers 4. This significantly simplifies the installation of the lock and simultaneously reduces the number of required fastening components.

[0052] Depending on the mechanical requirements, the number of spacers 4 inside the lock housing 22, 32 can be varied. For example, to create a particularly rigid lock, a greater or lesser number of spacers 4 can be provided inside the lock housing 22, 32. Furthermore, the functional components of the lock are designed as interchangeable functional modules. These functional modules themselves have corresponding spacers, so that when functional modules are inserted, the spacers 4 inside the lock housing 32 can be replaced. This further simplifies assembly, as the screw connections previously used to fasten the lock base and top can now also be used to fasten the functional modules. Reference symbol list
