Description

The invention relates to a mortise lock, in particular for a door or window sash, according to the preamble of claim 1 and claim 13.

Such a lock is from the DE 201 15 832 U1 known. A semicircular mounting adapter is provided for mounting the lock cylinder. This is attached by clamping. The mounting adapter is either fastened to the lock cylinder itself by means of a clamp connection or by spreading it in the lock cylinder receptacle.

The GB 2 500 605 A shows a lock with a lock cylinder adapter that can be inserted into the lock cylinder receptacle. The lock cylinder adapter is fastened indirectly in the lock by screwing the lock cylinder.

In the following description, for the sake of simplicity and brevity, only a door leaf or a door is mentioned, whereby the term “door leaf” or “door” in the sense of the invention also includes window sashes or windows and the like should.

Generic mortise locks usually have an essentially flat cuboid housing with a lock mechanism arranged therein. The lock housing has a continuous lock cylinder recess for receiving an associated lock cylinder. The lock housing with the lock mechanism contained therein can usually be pushed or inserted from the front side of the door leaf into a lock recess of the door there, after which the housing is fastened in the lock recess, in particular screwed to the door leaf.

After inserting or screwing the lock housing into the door leaf, the lock cylinder provided is inserted transversely to the door leaf plane and through the lock cylinder recess of the lock housing and screwed to the lock housing to prevent it from falling out or being pulled out. For additional fixation of the lock cylinder in the lock housing, in particular against tilting as well as against rotation, the clear cross section of the lock cylinder recess is usually designed in such a way that the mostly prismatically shaped lock cylinder is clear translationally (transversely to the locking cylinder longitudinal axis) and / or rotationally (around the locking cylinder longitudinal axis) Cross-section of the lock cylinder recess is fixed by means of a form fit.

Various lock cylinder types are known on the market, some of which differ in terms of their internal structure, but in particular on the basis of their external dimensions, in particular on the basis of the respective cross-sectional shape and size. For this reason, generic mortise locks are usually manufactured in different variants depending on which lock cylinder type is ultimately to be used for the respective door. For example, lock cylinders in the so-called “Euro profile” are known whose cylindrical area (“cylinder section”) has a diameter of 19 mm, while the cylinder section in the so-called “Swiss round profile” has a diameter of typically 22 mm.

The manufacture of mortise locks or at least their housings or housing walls in different variants, however, is complex and tends to be cost-intensive, since different manufacturing tools have to be created and kept ready for this in each case. The management and warehousing of the corresponding lock variants intended for use with different lock cylinder types also causes considerable effort on the part of the manufacturer as well as on the part of the dealer or customer. Last but not least, the fitter on the customer side must also ensure that he always selects the right lock variant for the lock cylinder type to be used and that he has it with him during assembly.

Against this background, the object of the present invention is to provide a mortise lock in which the number of lock variants can be reduced or minimized with respect to different lock cylinders to be used, so that as few different lock variants as possible can be planned, manufactured and kept in stock for different lock cylinders . to be carried by the fitter. In particular, the lock should be easy to assemble.

The object is achieved according to the invention by a mortise lock according to the features of patent claim 1 and by a mortise lock according to the features of patent claim 13.

The mortise lock according to the present invention is provided in an initially known manner for installation in the wing of a door or a window and the like and has a lock housing with a lock mechanism arranged therein. The lock mechanism can have a bolt and / or a lock latch, which are movably mounted in the lock housing, so that they can be extended and retracted when the lock mechanism is actuated. The lock mechanism preferably also has a connection socket that has a corresponding opening in the housing wall for connecting a handle or a motorized drive device is accessible. Furthermore, the lock mechanism can be equipped with a lock cylinder for key operation of the lock mechanism. For this purpose, a housing lock cylinder recess is formed in the housing wall of the lock housing. The lock housing thus comprises at least one housing wall that can be arranged essentially parallel to the plane of the window sash or door sash and the like. A housing lock cylinder recess is formed in the housing wall. This housing lock cylinder recess has a clear cross section which is designed such that a lock cylinder can be pushed through the clear cross section of the lock cylinder recess and can thus be arranged in the lock housing. In preferred embodiments, it can be provided that the clear cross-section of the housing lock cylinder recess is designed unspecifically in its cross-sectional size and / or in its clear cross-sectional contour, so that a plurality of different lock cylinders can be pushed through.

According to the invention, the mortise lock is characterized by an adapter receptacle arranged in the area of the housing lock cylinder recess for connecting a lock cylinder adapter to the lock housing. This connection can be made in that the adapter receptacle in the housing is designed as a recess in which the lock cylinder adapter can be inserted. Other connection mechanisms are also possible. It is essential that the lock cylinder adapter has an adapter lock cylinder recess with a smaller clear cross section compared to the housing lock cylinder recess, which is selected so that a lock cylinder can be inserted into the adapter lock cylinder recess in a form-fitting manner.

In other words, this means that, for example, different lock cylinder adapters can be provided, which can be arranged in the area of the adapter receptacle on one and the same variant of the lock housing and connected to the lock housing. In this way, different lock cylinders can be used or mounted together with one and the same lock housing, with only the appropriate lock cylinder adapter having to be arranged on the lock housing beforehand. The lock cylinder adapter thus represents an exchangeable element which ensures the required, at least translational, positive locking transversely to the cylinder longitudinal axis between the lock cylinder and the lock housing.

Thus, thanks to the invention, the number of housing variants of a mortise lock to be produced, managed and kept in stock can be significantly reduced. Ideally, the customer only needs to keep one lock or housing variant and the required lock cylinder adapter ready for each lock type, and the fitter also only has to carry one variant (together with a set of matching lock cylinder adapters) for each lock type.

According to a preferred embodiment of the invention, the clear cross-section of the housing lock cylinder recess also matches the cross-sectional shape of the lock cylinder in a tumbler section of the lock cylinder and / or in a cylinder section of the lock cylinder, at least in some areas, in such a way that between a lock cylinder inserted through the lock housing and the clear cross section the housing lock cylinder recess is positively locked (transversely to the lock cylinder longitudinal axis, or with respect to rotation of the lock cylinder), thus preventing undesired rotation of the lock cylinder housing in the lock housing.

With this design of the housing lock cylinder recess, in particular the fact is taken into account that different lock cylinder types common on the market differ in terms of their cross section in the cylinder section of the lock cylinder housing in which the rotatable part of the lock cylinder is arranged, whereas different common lock cylinder types have at least one Have so-called tumbler section corresponding in cross section. The tumbler section can contain all or some of the tumblers of the lock cylinder, for example in the case of the Euro profile, but also serves to anchor the lock cylinder in the lock housing in terms of translation (pulling out the lock cylinder housing) and in terms of rotation in different lock cylinder types, for example in the Euro profile and the Swiss round profile (Twisting the lock cylinder housing).

With the design of the clear cross-section of the housing lock cylinder recess corresponding to the shape of the tumbler section of the same cross-section of several lock cylinder types, the compatibility of the lock housing with these lock cylinder types, but in particular the anchoring of the lock cylinder in the lock housing, can be further improved. In addition, the lock cylinder adapter can be made particularly compact in this way, since it only has to cover the cylinder section of the lock cylinder, but not necessarily also the tumbler section of the lock cylinder, or it has to be in positive contact with the lock cylinder in these areas.

It can also be provided that the clear cross-section of the adapter lock cylinder recess corresponds at least in some areas to the cross-sectional shape of the lock cylinder in a tumbler section of the lock cylinder and / or in a cylinder section of the lock cylinder in such a way that between a lock cylinder inserted through the lock housing and the clear cross section of the There is an adapter lock cylinder recess, preferably transversely to the lock cylinder longitudinal axis and / with respect to the rotation of the lock cylinder. In this embodiment, the lock cylinder adapter assumes the form-locking fixation of the lock cylinder relative to the lock housing not only in the cylinder section, but also in the tumbler section of the lock cylinder used in each case.

According to a further preferred embodiment, the mortise lock has at least two housing walls arranged essentially parallel to the door leaf, each with a housing lock cylinder recess. Each housing wall is assigned an adapter receptacle arranged in the area of the housing lock cylinder recess for connecting a lock cylinder adapter to the lock housing. In this way, a form fit between the lock housing and the lock cylinder on both sides with respect to the lock housing is achieved via the at least two housing walls with the at least two lock cylinder recesses or with the at least two lock cylinder adapters, so that a particularly secure form fit between the lock cylinder and lock housing with regard to tilting of the lock cylinder results.

According to a further preferred embodiment of the invention, the entire inner contour of the clear cross section of the adapter lock cylinder recess of the at least one lock cylinder adapter rests positively on the lock cylinder used in each case. This results in a particularly robust form fit between the lock cylinder and the lock cylinder adapter, and also provides better protection against the ingress of dirt into the lock mechanism.

The mortise lock according to patent claim 1 provides that the lock cylinder adapter and the adapter receptacle on the lock housing have latching elements that correspond to one another in shape for connecting the lock cylinder adapter and adapter receptacle. This results in the possibility of a particularly simple connection or separation of the adapter and the housing wall, without tools or fastening elements being necessary for this. This is particularly beneficial for easy and quick lock assembly on site.

The adapter receptacle is preferably designed as a recess in the housing wall. This on the one hand facilitates the positioning of the lock cylinder adapter during assembly, and on the other hand this results in an outwardly flush closure of the lock cylinder adapter with the housing wall.

A further preferred embodiment of the invention provides that the lock cylinder adapter is designed as a flat body and has latching formations which can be connected to latching recesses in the housing wall that correspond in shape to the latching formations. This configuration also makes it easier to handle, position and assemble the lock cylinder adapter on the lock housing.

According to a further embodiment of the invention, the lock cylinder adapter essentially has the shape of an open circular ring with an essentially circular, eccentric adapter lock cylinder recess. In this case, the lock cylinder adapter can be arranged so as to snap into a substantially circular area of the housing lock cylinder recess. The design of the lock cylinder adapter according to this embodiment of the invention is particularly compact, and in particular also allows the largely unchanged use of an existing lock housing, for example a lock housing for a Swiss round profile, together with the lock cylinder adapter according to this embodiment, as well as other lock cylinders, for example lock cylinders with a Euro profile to be used together with the existing lock housing.

The lock cylinder adapter is preferably designed as a plastic injection-molded part, which enables the lock cylinder adapter to be designed in a cost-effective and manageable and assembly-friendly manner.

A further embodiment of the invention provides that at least two lock cylinder adapters that can be arranged on different housing walls are connected to one another or formed in one piece. In this embodiment, several, preferably two, lock cylinder adapters are combined to form a preferably one-piece block. This results in easier handling of the lock cylinder adapter for certain lock housing types, since instead of several or two separate adapters only one, preferably one-piece, lock cylinder adapter block has to be handled.

Another particularly preferred embodiment of the invention provides that the Lock cylinder adapter can be selected from a set of differently shaped adapters, the different adapters each being specifically designed for the use of different lock cylinder types. This embodiment enables the mortise lock according to the invention to be designed in the sense of a modular construction system, in that in this way various or all common lock cylinder types can be essentially combined with one and the same mortise lock or lock housing.

In the mortise lock according to claim 13, the lock cylinder adapter is connected in one piece with the lock housing or with a lock component. The lock cylinder adapter can preferably be designed as a one-piece component of the housing wall. The one-piece connection of the lock cylinder adapter with the lock housing, lock component or with the housing wall can preferably have a predetermined breaking point for the user to remove the lock cylinder adapter. In this way, the number of parts and thus manufacturing costs can be further reduced, there is protection against loss for the lock cylinder adapter, and the predetermined breaking point makes it possible to remove the lock cylinder adapter from the lock without tools
Lock housing by the fitter by simply breaking out the lock cylinder adapter.

Embodiments are also provided in which the clear cross section of the adapter lock cylinder recess can be produced and / or expanded by breaking out material. Here, one or more predetermined breaking points can be provided as a shape specification and to facilitate breaking out. In this way, for example, one and the same adapter without or with broken cross-sectional areas can be used for mounting different types of lock cylinders, preferably with the same lock housing.

Preferably, all of the embodiments discussed can be implemented independently of the shape of the clear cross section of the housing lock cylinder recess, as long as all the provided lock cylinder types fit or can be pushed through the clear cross section of the housing lock cylinder recess.

According to a preferred embodiment of the invention, however, the cross-section of the housing lock cylinder recess also matches the cross-sectional shape of a lock cylinder type, at least in some areas, in such a way that there is a form fit transversely to the lock cylinder longitudinal axis between a lock cylinder of the aforementioned lock cylinder type inserted through the lock housing and the housing wall. In this context, it can be provided that the clear cross-section of the housing lock cylinder recess corresponds at least in some areas to the cross-sectional shape of a first lock cylinder, in such a way that there is a direct form fit between the inserted first lock cylinder and the housing lock cylinder recess transversely to the cylinder longitudinal axis, and that a The housing lock cylinder recess is provided with a lock cylinder adapter that can be connected to the housing wall in the area of an adapter receptacle and has a second clear cross section that is smaller than the first clear cross section, the second clear cross section having the cross-sectional shape of a second lock cylinder with a smaller cross section than the first lock cylinder coincides in such a way that by means of the lock cylinder adapter between the inserted second lock cylinder and the adapter lock cylinder recess form fit transversely to r cylinder longitudinal axis exists.

In preferred embodiments, the cross section of the lock cylinder recess on the lock housing can be shaped, for example, so that lock cylinders of a first type with a larger cross section (e.g. Swiss round profile) without a lock cylinder adapter fit or can be inserted directly into the lock housing in a form-fitting manner, while the use of lock cylinders is a or several types with a smaller cross section (for example Euro profile) in the same lock housing, as in the previous embodiments, is possible via a correspondingly matching lock cylinder adapter.

With this embodiment, one lock cylinder adapter, namely that for the lock cylinder type with the largest provided in cross section, can thus be saved. In this embodiment, too, a first lock cylinder adapter with a first lock cylinder recess or a second or further lock cylinder adapter with a second or with further lock cylinder recesses can be inserted into the adapter receptacle on the lock housing. In this way, in addition to the largest type of lock cylinder in cross section (which is guided in a form-fitting manner by the housing lock cylinder recess itself and therefore does not require a lock cylinder adapter), not only one, but also two or more other lock cylinder types (smaller in cross section) can be combined with the same lock housing The appropriate adapter is assigned to the smaller lock cylinder types and inserted into the adapter receptacle on the lock housing.

The invention further relates to a sales unit comprising a mortise lock as described above and a lock cylinder adapter, preferably a pair of lock cylinder adapters or a set of lock cylinder adapters, preferably a set of lock cylinder adapter pairs. The sales unit is advantageous in that in this way one and the same mortise lock or lock housing, together with the enclosed set of lock cylinder adapters, already covers several or all common lock cylinder types and can thus be installed together with several or all common lock cylinder types. The sales unit thus allows considerable simplifications and savings in the storage, management and handling of mortise locks.

For the sake of simplicity and clarity, only the housing walls are essentially in each case in all figures 2 , 2 ' of the lock housing shown, but not the lock mechanism and the like. The lock mechanism, not shown, is between the housing walls 2 , 2 ' arranged. The two walls of the case 2 , 2 ' form the lock housing. They are connected to one another via spacer elements (not shown) so that they each form a flat housing in which the two housing walls 2 , 2 ' are arranged parallel to one another at a mutual distance. The lock mechanism can each include a lock latch and / or a bolt. The lock latch and the bolt are movably mounted in the lock housing in such a way that they can assume a position retracted into the lock housing and a position extended out of the lock housing. The lock mechanism also has an actuating device, for example a nut, to which a handle or a motorized actuating device can be connected. Furthermore, the lock mechanism in the present case has a lock cylinder. In the housing walls shown in the figures 2 , 2 ' are a circular recess 2n for the lock follower and a lock cylinder recess 3 for holding the lock cylinder 4th , 6th intended. The so-called faceplate is formed on a longitudinal end face of the lock housing, on which the bolt and / or the latch extend into their extended position. On this faceplate side, the lock housing usually carries a so-called faceplate plate, which has faceplate openings through which the bolt or latch extends and retracts. The faceplate is the same as the lock mechanism is not shown in the illustrated embodiments. Only the housing walls are shown 2 , 2 ' with the lock cylinder adapters arranged there 7th , 7 ' and the lock cylinders to be used 4th , 6th .

The embodiment according to the invention of FIGS. 1 to 6 (drawing sheet 1 / 7th )

The 1 to 6th show a first embodiment of a mortise lock 1 according to the present invention. The lock mechanism is not shown 1 to 3 the mortise lock with the lock cylinder adapter inserted 7th , where in the 2 and 3 is shown as a lock cylinder 4th a first type of lock cylinder in the lock housing 1 can be used. The lock cylinder 4th with its circumferential contour fits positively into the clear cross-section of the adapter lock cylinder recesses 3 ' of the two lock cylinder adapters 7th , 7 ' . The lock cylinder adapter 7th are in turn form-fitting with the housing walls 2 , 2 ' connected by placing them in adapter mounts 5 in the housing walls 2 , 2 ' are used. The adapter mounts 5 are in the present embodiment as recesses in the housing walls 2 , 2 ' are formed, in which the lock cylinder adapter 7th can be used positively. In the illustrated embodiment, the lock cylinder 4th thus with regard to translation transversely to the cylinder longitudinal axis by means of the lock cylinder adapter 7th relative to the housing walls 2 , 2 ' of the mortise lock 1 positively fixed. The lock cylinder 4th is symmetrical in the illustrated case with the formation of two symmetrical, axial sections on both sides of the central cross-sectional plane. Hence the two lock cylinder adapters 7th , 7 ' that are in the housing walls 2 , 2 ' are used, identical, ie with identical adapter lock cylinder recesses 3 , 3 ' educated. Also the adapter mounts 5 in the housing walls 2 , 2 ' are designed identically.

4th to 6th show the same mortise lock 1 according to 1 to 3 but with the lock cylinder adapter removed 7th . By removing the lock cylinder adapter 7th according to 4th in the illustrated embodiment, the clear cross section of the housing lock cylinder recess 3 opened or accessible. The light one
Cross section of the housing lock cylinder recess 3 is larger than the clear cross section of the adapter lock cylinder recess 3 ' the lock cylinder adapter 7th . Therefore, when the lock cylinder adapters 7th a lock cylinder 6th another lock cylinder type in the mortise lock 1 be inserted, the lock cylinder 6th in this embodiment with its circumferential contour positively in the clear cross section of the housing lock cylinder recess 3 fits. The lock cylinder 6th is thus transverse to the longitudinal axis of the cylinder with respect to translation through direct contact with the edges of the housing lock cylinder recess 3 out without the need for a lock cylinder adapter 7th necessary is.

The lock cylinder 4th of the first lock cylinder type according to 2 and 3 and the lock cylinder 6th of the second lock cylinder type according to 5 and 6th differ in their cross-sectional dimensions essentially in the respective cylinder section 8th . With the lock cylinder 4th of the first lock cylinder type according to 2 and 3 it is a lock cylinder with a "Euro profile", while the lock cylinder 6th of the second lock cylinder type according to 5 and 6th is of the "Swiss round profile" type. Both lock cylinder types 4th and 6th however, are correct in terms of their cross-section in the tumbler section 9 match. The guard locking section 9 of both lock cylinder types 4th and 6th can thus from the same area 11 the housing lock cylinder recess 3 be included in such a way that the lock cylinder 4th or. 6th with respect to rotation around the cylinder longitudinal axis, form-fit on the housing walls 2 , 2 ' of the lock housing 1 is present. For this reason, the lock cylinder adapter 7th be kept comparatively compact because the lock cylinder adapter 7th only the positive fixation with regard to translation transversely to the cylinder longitudinal axis of the smaller Euro profile lock cylinder 4th must ensure while both lock cylinder types 4th and 6th with regard to rotation already through the immediate application of their respective tumbler section 9 at the contour of the area 11 the housing lock cylinder recess 3 are fixed.
This means: In the 1 to 3 it is provided that a Euro profile lock cylinder 4th using a lock cylinder adapter 7th is used in the lock housing. This is in both housing walls 2 , 2 ' in the respective adapter mount 5 one lock cylinder adapter each 7th used. The adapters 7th each have an adapter lock cylinder mount 3 ' in which the lock cylinder 4th Is used positively.

The 4th to 6th show the same lock housing as in the 1 to 3 , the lock cylinder adapter 7th , 7 ' however are removed and instead of the Euro profile lock cylinder 4th a Swiss round profile lock cylinder 6th directly into the housing lock cylinder recess 3 the housing walls 2 , 2 ' is used and is thus held in a form-fitting manner without a lock cylinder adapter.

The embodiment of Figures 7 and 8 (drawing sheet 2 / 7th )

The 7th and 8th show two different versions of a lock cylinder adapter 7th . The lock cylinder adapter according to the invention according to 7th is designed as a plastic injection-molded part and has locking formations 10 ' , which are designed so that they are in shape-corresponding locking recesses 10 in the area of as Recesses formed adapter mounts 5 in the housing walls 2 , 2 ' (see. 4th ) can be snapped into place. In addition, the lock cylinder adapter has 7th according to 7th a substantially eccentric circular elevation 12th that when the lock cylinder adapter 7th positively in the circular area of the housing lock cylinder recess 3 the housing walls 2 , 2 ' comes to the plant (cf. 1 and 4th ), and so the lock cylinder 4th of the smaller lock cylinder type according to 2 and 3 form-fitting reliable relative to the housing walls 2 , 2 ' fixed.

The lock cylinder adapter not according to the invention according to 8th is a flat variant made of sheet metal, for example, which is an alternative to the lock cylinder adapter according to FIG 7th in the same or similar, as depressions in the housing walls 2 , 2 ' trained adapter mounts 5 arranged, for example, can be pressed.

The non-inventive embodiment of Figures 9 to 15 (drawing sheet 3/7)

The content of the 9 to 14th essentially corresponds to the content of the 1 to 6th with the difference that in the 9 to 14th a lock cylinder adapter 7th with an essentially open circular shape (see enlarged view of the lock cylinder adapter 7th in 15th ) is used, with the lock cylinder adapter 7th according to 9 to 11 and 15th a substantially circular, eccentric lock cylinder recess 3 ' having. Due to this design, the lock cylinder adapter 7th according to 9 to 11 and 15th especially together with a largely unchanged, existing lock housing 1 can be used, for example with a lock housing 1 according to 9 to 14th , which was originally only used for the installation of a lock cylinder 6th of the type "Swiss round profile" was or is intended. In this way, thanks to the lock cylinder adapter 7th according to 9 to 11 and 15th also other lock cylinders, for example lock cylinders 4th with Euro profile, can be installed in the existing lock housing for locking cylinders of the "Swiss round profile" type.

The embodiment of FIGS. 16 to 22 (drawing sheet 4th / 7th )

The 16 to 21 of the drawing sheet 4th / 7th agree with the content 9 to 14th of the drawing sheet 3 / 7th except for the lock cylinder adapter 7th , 7 ' according to 16 to 18th and 22nd . In the embodiment according to 16 to 22nd are in contrast to the embodiment according to 9 to 14th two lock cylinder adapters 7th , 7 ' to a one-piece lock cylinder adapter block according to 22nd connected, in particular the handling and assembly of the lock cylinder adapter 7th , 7 ' facilitated. The embodiment according to 16 to 22nd is particularly suitable for mounting the lock cylinder adapter 7th , 7 ' ex works, with the corresponding mortise lock 1 in this case can be implemented in two variants, namely once with a mounted lock cylinder adapter 7th , 7 ' according to 17th , and once without a lock cylinder adapter 7th , 7 ' according to 20th . The advantage of reducing the number of variants remains at least with regard to the production of the lock housing with the housing walls 2 , 2 ' also obtained in this embodiment.

The embodiment not according to the invention of FIGS. 23 to 29 (drawing sheet 5 / 7th )

23 to 29 show a further embodiment of a mortise lock. In contrast to the previous embodiments, this is the housing-side adapter receptacle 5 as a breakthrough or recess in the housing wall 2 , 2 ' of the lock housing 1 designed, and from the outset basically to accommodate different lock cylinder adapters 7 ' , 7 " provided, their different clear cross-sections each to accommodate different types of lock cylinders 4th , 6th are trained. In other words, this means that, in contrast to the embodiments according to FIG 1 to 22nd Regardless of which type of lock cylinder is to be installed in the mortise lock, a lock cylinder adapter as a rule 7 ' , 7 " come into use.
