The present invention relates to a door fitting for actuating a door locking mechanism of a door. The invention further relates to a door equipped with a door locking mechanism with such a door fitting.
Doors which are equipped with such a door fitting or such a door locking mechanism may be normal house entrance doors. In such cases, however, they are preferably balcony doors or terrace doors.
A door fitting usually comprises an outer doorplate for mounting on the outside of the door and an inner doorplate for mounting on the inside of the door. Each doorplate covers openings that have been created in the door, through which a door locking mechanism fitted in the door can be accessed. Such a door locking mechanism typically comprises a mortise lock with a follower, which is equipped with a rectangular opening for actuating at least one latch of the mortise lock. An actuator rod may be pushed through the follower or the rectangular opening therein, and may be used to rotate the follower. This actuator rod expediently has a rectangular cross section. Then, said actuator rod must be pushed through the aforementioned openings formed in the door. The actuator rod also passes through further openings which are formed in the respective doorplate. The respective door fitting may then have one or two door openers, which are connected in non-rotating manner with the respective lengthwise end of the actuator rod at the respective doorplate. Such door openers may be designed as latches or as round handles or rotating knobs.
In this context, a central component of the door locking mechanism is the mortise lock, which is fitted in the narrow face of the door panel and includes said follower and the latch coupled thereto. Modern door locking mechanisms have at least one further latch, which is also coupled with the follower for drive purposes, and is arranged at a distance from the mortise lock in the door panel. In addition, the door locking mechanism may typically also be equipped with at least one bolt, which can be actuated with a barrel lock. In this context, the bolt and the latch may be separate components. Embodiments are also conceivable in which the latch may serve at the same time as the bolt, for example by extending it beyond its normal closure position additionally into a bolting position. This bolt is practically also conformed in the aforementioned mortise lock. Here too, it is conceivable to equip the door locking mechanism with at least one further bolt, which is integrated in the door at a distance from the mortise lock. Here too, it is conceivable to integrate the latch and the bolt in each other. In order to be able to insert such a barrel lock through the door and into the mortise lock and the door locking mechanism, openings are also necessary in the door. The respective doorplate may also have an opening suitable for a barrel lock, to enable the barrel lock to be actuated. Such a barrel lock may be actuated with a key, preferably on the outside of the door, and with a toggle which may preferably be provided on the inner side of the door. Accordingly, the door fitting may include the door openers, the barrel lock, and optionally a toggle as further components.
In order to fasten the doorplates to the door, an internal fastening may be used for reasons of security, to make it more difficult to remove the outer doorplate. For such an internal fastening, threaded connections are preferred in which the head of a screw bears on the inner doorplate, extends through the door and is screwed into a screw-in opening conformed on the outer doorplate. The door has two further passthrough openings to allow these screws to pass through. The positions of these passthrough openings relative to each other and relative to the door may vary depending on the respective door locking mechanism. Some mortise locks require that the passthrough openings for the screws are routed outside the mortise lock. In other mortise locks it is provided that one of two passthrough openings is routed through the mortise lock, while the other passthrough opening must be routed outside the mortise lock. Still other types require that both passthrough openings must pass through the mortise lock. In addition to all the above, depending on the type of mortise lock the follower may be positioned above the lock cylinder or below the lock cylinder, which means that the relative positions of the threaded joints on the door may also be varied. The logistical expense and the costs of providing a large number of different door fittings are relatively high.
The present invention addresses the problem of describing an improved or at least a different embodiment of a door fitting of the type described previously, or a door equipped therewith, which is characterised particularly in that the respective door fitting can be used for multiple different door locking mechanisms.
This problem is solved according to the invention with the objects of the independent claims. Advantageous embodiments are objects of the dependent claims.
The invention is based on the general idea of designing the screwing points on the outer doorplate and on the inner doorplate via which the internal threaded joint is to be created between the outer doorplate and the inner doorplate through the door, so that they are displaceable relative to a longitudinal direction of the door fitting. In this way, a relative position of the screwing points with respect to each other and relative to the respective doorplate can be altered. This in turn enables an adjustment to various configurations and types of door locking mechanism. Accordingly, the door fitting according to the invention is usable for many different variants of door locking mechanism.
In detail, the door fitting according to the invention comprises an outer doorplate for mounting on an outer side of the door and an inner doorplate on an inner side of the door. The inner side of the outer doorplate, facing towards the inner doorplate has a first screw-in opening in a first end section of the door fitting, into which a shaft of a first screw may be screwed to fasten the outer doorplate to the door, and a second screw-in opening in a second end section of the door fitting at a distance from the first end section in the lengthwise direction of the door fitting, into which a shaft of a second screw can be screwed to fasten the outer doorplate to the door. The inner doorplate has a mounting plate and a covering plate that covers the mounting plate on the side outer side facing away from the outer doorplate. The first end section of the inner doorplate mounting plate has a first passthrough opening, through which the shaft of the first screw may be passed to fasten the mounting plate to the door, and the second end section has a second passthrough opening through which the shaft of the second screw may be passed to fasten the mounting plate to the door. The mounting plate also has a first bearing point on the outer side thereof, in the area of the first passthrough opening, on which a head of the first screw may bear either indirectly, e.g. via a washer, or directly, and a second bearing point in the area of the second passthrough opening, on which a head of the second screw may bear either indirectly, e.g. via a washer, or directly. It is further provided that when the door fitting is in the mounted state, the head of the first screw bears on the first bearing point, protrudes with its shaft through the first passthrough opening and through the door, and is screwed into the first screw-in opening. At the same time, the head of the second screw bears on the second bearing point and the shaft thereof protrudes through the second passthrough opening and through the door, and is screwed into the second screw-in opening. In this way, an internal threaded connection is created between the mounting plate and the outer doorplate through the door. In the mounted state, the inner doorplate is completed with the cover plate, wherein the cover plate then covers the mounting plate on the outer side thereof, so that the internal threaded connection is not visible, and also not accessible from the inner side of the door.
For the displaceability of the screwing point suggested according to the invention, it may now particularly be provided that the first screw-in opening and/or the second screw-in opening is/are arranged on the outer doorplate so as to be displaceable in the lengthwise direction of the door fitting, so that various distances may be set between the two screw-in openings and different relative positions may be set between the outer doorplate and the first screw-in opening and between the outer doorplate and the second screw-in opening.
According to an advantageous embodiment, the first passthrough opening may be configured with the first bearing point and/or the second passthrough opening may be configured with the second bearing point such that they allows the passing though and the bearing of the respective screw for various relative positions between the outer doorplate and the first screw-in opening and/or between the outer doorplate and the second screw-in opening. In other words, the respective passthrough opening is preferably not displaceable itself relative to the lengthwise direction of the door fitting, but it does enable the position of the bearing point for the screw head to be varied in the lengthwise direction.
According to an advantageous embodiment, the first screw-in opening may be conformed on a first carriage, which is arranged in a first carriage guide secured in the first end section on the outer doorplate so as to be displaceable in the lengthwise direction of the door fitting. Additionally or alternatively thereto, the second screw-in opening may be conformed on a second carriage, which is arranged in a second carriage guide secured in the second end section on the outer doorplate so as to be displaceable in the lengthwise direction of the door fitting. Thus, the respective carriage is displaceable in the lengthwise direction along the associated carriage guide, while it is supported against the carriage guide perpendicularly to the lengthwise direction. In this way, particularly tractive forces which are introduced into the carriage when the respective screw is tightened may be supported on the outer doorplate via the associated carriage guide. For this purpose, the respective carriage guide is fastened to the inside of the outer doorplate by suitable means. A welded joint is conceivable, for example.
In an advantageous refinement, the respective carriage guide may have a bracket which is fastened to the outer doorplate and a guide opening that extends in the lengthwise direction of the door fitting. As described earlier, the bracket may expediently be fastened to the outer doorplate by means of a welded joint. The bracket may then have a guide wall located at a distance from the inner side of the outer doorplate, in which the guide opening is formed and is delimited transversely to the lengthwise direction of the door fitting by two guide wall sections. The respective carriage may then protrude through the respective guide opening and engage in positive locking manner with the associated guide wall sections. In this way, the respective carriage may be braced against the bracket via the guide wall sections so that it is able to transmit the tractive forces described previously to the outer doorplate.
According to an advantageous refinement, the respective carriage may have a seating groove extending in the lengthwise direction of the door fitting for each guide wall section, with each of which one of the guide wall sections engages. To this extent, one groove and spring guide is created in conjunction with the respective carriage guide wall section on two sides of the respective carriage facing away from each other. Such a groove and spring guide or drawer guide not only ensures simple, guided displaceability of the carriage along the carriage guide but also serves to transmit powerful forces transversely to the direction of the guide.
The respective carriage may advantageously have a socket element which is fastened to the carriage body and displaceable along the respective carriage guide, and which contains the respective screw-in opening. This serves to make the respective carriage easier to manufacture.
A refinement in which the seating grooves are conformed on the carriage body is particularly advantageous. This enables a relatively compact construction of the socket element. The socket element may also be arranged centrally between the guide wall sections, and therewith in the region of the guide opening.
Another embodiment suggests that the respective carriage body has a lower part and an upper part, which may be fastened to each other by suitable means. This also simplifies the manufacture of the carriage. The socket element may then expediently have a screwing section with an external thread, while the lower part of the carriage body has a socket section with an internal thread that matches the external thread. In this way, the screwing section of the socket element may be screwed into the socket section of the lower part. Additionally, it may advantageously be provided that the upper part of the carriage body has a passthrough opening, which is in such a position and of such a size that the upper part may be fastened to the lower part with the aid of the socket element by screwing the screwing section into the socket section through the passthrough opening. At the same time, an area of the socket element protruding radially above the screwing section is braced against the upper part, namely against a border surrounding the passthrough opening. In this way, the upper part may be attached to the lower part with the aid of the socket element. The socket section may project away from the rest of the lower part and protrude axially into the passthrough opening of the upper part.
In an advantageous embodiment, the lower part may be arranged on an underside of the guide wall facing the inner side of the outer doorplate, so that the socket section is guided in the guide opening, and a lower part base, from which the socket section projects, engages behind the two guide wall sections transversely to the lengthwise direction of the door fitting. At the same time, the upper part may be arranged on an upper side facing away from the inner side of the outer door fitting, so that the passthrough opening is aligned with the socket section, and an upper part base which contains the passthrough opening engages across the two guide wall sections transversely to the lengthwise direction of the door fitting. When assembled, the lower part base and the upper part base in conjunction with the socket section form the seating grooves described earlier, in each of which one of the guide wall sections engages. The upper part, the lower part and the socket element may then be synchronised with each other so that when the socket element is tightened, that is to say when the screwing section is screwed tightly into the socket section, the lower part base and the upper part base press against the two guide wall sections to create a frictional retention of the respective carriage in the respective relative position along the guide opening. When the socket element is loosened, the frictional fastening is released, so that the carriage can be displaced along the guide opening, or along the guide wall sections.
According to another advantageous embodiment, it is suggested that a protruding pin be conformed on each side of the socket section on the lower part base, and is inserted through a pin passthrough opening in the respective guide wall section into a pin seating conformed on the upper part base. Alternatively, it may also be provided that a protruding pin is conformed on each side of the passthrough opening on the upper part base, and is inserted through a pin passthrough opening in the respective guide wall section into a pin seating conformed on the lower part base. The pin connection between the lower part base and the upper part base serves to prevent the lower part base and the upper part from twisting with respect to each other. The respective pin extending through the respective pin passthrough opening in the associated guide wall section also fixes the carriage on the carriage guide in the lengthwise direction of the door fitting in form-locking manner, which helps to secure the carriage more firmly for the screwing connection.
Another advantageous refinement provides that the respective guide wall section has several separate pin passthrough openings for at least two predefined relative positions between the outer doorplate and the first screw-in opening and/or the second screw-in opening, arranged at a distance from each other in the lengthwise direction of the door fitting. In other words, two or three or more separate and discrete pin passthrough openings then provided for two or three or more predefined relative positions, to enable the respective desired positioning of the carriage along the guide opening on the carriage guide.
Additionally or alternatively, it is also possible that the respective guide wall section has a common pin passthrough opening for at least two predefined relative positions between the outer doorplate and the first screw-in opening and/or the second screw-in opening, extending as an elongated slot in the lengthwise direction of the door fitting. In this way, an almost unlimited number of positions may be set for the carriage along the carriage guide.
However, a refinement is preferred in which a screen is created in the pin passthrough opening in the form of an elongated slot, which screen only permits the respective pin to pass through the pin passthrough opening when the predefined relative positions exist between the outer doorplate and the first screw-in opening and/or the second screw-in opening, and prevents the pin that has passed through this pin passthrough opening from being pushed in the lengthwise direction of the door fitting. The screen as well as the discrete and separate pin passthrough openings thus make the task of setting predefined relative positions considerably simpler for the fitter.
Advantageously for the embodiments described above which have separate pin passthrough openings and for shared passthrough openings which have a screen, with a screen described in the preceding text, the upper part, lower part and socket element are synchronised with each other so that the threaded joint between the screwing section and the socket section may be loosened to such an extent that the respective pin can be moved out of the respective pin passthrough opening without having to remove the socket element completely from the lower part of the carriage for this purpose. In this way, the carriage may then be shifted as a unit along the carriage guide to set the desired relative position. Once the desired relative position has been found, the threaded joint between the screwing section and the socket section may be tightened again. Since in this configuration the position of the carriage relative to the carriage guide is secured by the separate pin passthrough openings or by the screen in the respective common pin passthrough opening, when the threaded joint between the screwing section and the socket section is tight the respective guide wall sections between the lower part base and the upper part base must not be placed under any tension. In general, however, an embodiment is preferred in which such a tension of the guide wall sections between the lower part base and the upper part base does occur when the screwing section is screwed tight to the socket section.
As was explained earlier, the socket section preferably projects away from the rest of the lower part, preferably towards the upper part. In this context, it is particularly advantageous if the socket section protrudes axially into the passthrough opening of the upper part, at least when the screwing section is screwed tightly to the socket section for fixing the relative position of the carriage on the carriage guide.
In another advantageous embodiment, it is suggested that a tool engagement point be conformed radially outwardly on the socket element, via which a torque may be applied by means of a tool. In this way, a predefined and preferably relatively large torque can be applied to tighten and loosen the screwed joint between the screwing section and the socket section with the aid of a suitable tool. This ensures that when loosening a screw that is screwed into the screw-in opening in the socket element to affix the mounting plate and the outer doorplate on the door, the torque required to loosen the screw in the screwed joint between the screw shaft and the screw-in opening is less than the torque required to loosen the screwed connection between the screwing section and the socket section.
A door according to the invention comprises a door locking mechanism for securing the door in a door frame in the closed state, and is also furnished with a door fitting of the type described in the preceding text, which serves to actuate the door locking mechanism.
It goes without saying the door fitting may additionally include at least one door opener, in the form of a latch or in the form of a rotating knob and/or a barrel lock for example. Said screws and possibly suitable washers may also be included as part of the door fitting. The actuator rod for coupling the respective door openers with the follower of the door locking mechanism may also belong to the door fitting equipment.
Further important features and advantages of the invention will be evident from the subordinate claims, the drawing and the associated description of the figures with reference to the drawing.
Of course, the features described previously and those that will be explained in the following text are usable not only in the combinations described but also in other combinations or individually without departing from the scope of the present invention.
Preferred embodiments of the invention are represented in the drawing and will be explained in greater detail in the following description, wherein identical or similar or functional equivalent components are identified with the same reference signs.
In the drawing, of which all parts are represented schematically,
According to
Modern door locking mechanisms 2 may include additional latches 5 and/or additional bolts 6 for increased security, which are also integrated in door panel 3 and are then arranged above or below mortise lock 4 and at a distance from mortise lock 4.
Latch 5 is typically actuated via door openers 7, 8, which in this case are in the form of latches. To ensure that the respective door handle 7, 8 is able to cooperate through door panel 3 with door locking mechanism 2 and mortise lock 4 to actuate the latch 5, a first actuating opening 9 must be created in door panel 3. For example, an actuating pin 10 as shown in
In order to actuate bolt 6, a barrel lock 11 as shown in
Door 1 is further equipped with a door fitting 15, which generally serves to actuate door locking mechanism 2 and may accordingly comprise actuating pin 10 and also the barrel lock 11. Door fitting 15 may also comprise door openers 7, 8 and toggle 81. Regardless of the components mentioned earlier, at all events door fitting 15 comprises an outer doorplate 16 for mounting on the door outer side 13 and an inner doorplate 17 for mounting on the door inner side 14. Outer doorplate 16 and inner doorplate 17 are fastened to each other via an internal threaded joint 18 through door panel 3, and thus are also fastened to door 1 and door panel 3. In order to create this internal threaded joint 18 at least two screw passthrough openings are created in door panel 3, in particular a first screw passthrough opening 19 and a second screw passthrough opening 20, through which a screw, particularly a first screw 21 and a second screw 22 may be passed, as shown in
According to
For this purpose, as shown in
First screw-in opening 25 and/or second screw-in opening 29 is arranged on outer doorplate 16 so as to be displaceable in the lengthwise direction 27 of door fitting 15. In this way, various distances may be set between first screw-in opening 25 and second screw-in opening 29, and various relative positions between outer doorplate 16 and the respective screw-in opening 25, 29. Preferably, the two screw-in openings 25, 29 are each arranged so as to be displaceable in lengthwise direction 27 of door fitting 15 relative to outer doorplate 16. It is further provided that first passthrough opening 34 with first bearing point 36 and/or second passthrough opening 35 with second bearing point 38 are designed such that they allow the respective screw 21, 22 to pass through and bear on the bearing point for various relative positions between outer doorplate 16 and first screw-in opening 25 and/or second screw-in opening 29. It is also advantageously provided here that both passthrough openings 34, 35 with the associated bearing point 36, 38 allow the respective screw 21, 22 to pass through and bear on the bearing point for various relative positions between outer doorplate 16 and the respective screw-in opening 25, 29, so that in each case a consistent alignment between outer doorplate 16 and inner doorplate 17 may be set, aligned transversely to the plane of door panel 3. In the example of
With regard to the displaceability of screw-in openings 25, 29, it is provided in the door fitting 15 presented here, particularly according to
Each respective carriage guide 43, 45 is equipped with a bracket 46 or 47 fasted to outer doorplate 16 and a guide opening 48, 49 extending in the lengthwise direction 27 of door fitting 15. Bracket 46, 47 has a guide wall 50, 51 which is located at a distance from the inner side 23 of outer doorplate 16, and in which the guide opening 48, 49 is formed. Two guide wall sections 50a, 50b and 51a, 51b delimit the respective guide opening 48, 49 transversely to the lengthwise direction 27 of door fitting 15. The associated carriage 42 or 44 passes through respective guide opening 48, 49 and is in form-locking engagement with the associated guide wall sections 50a, 50b and 51a, 51b. The interaction between the respective carriages 42, 44 and the associated carriage guide 43, 45 is represented in greater detail in
The embodiment shown here is particularly advantageous, since carriage body 53 has a lower part 55 and an upper part 56. Socket element 54 also has a screwing section 57, which is furnished with an external thread. Lower part 55 is equipped with a socket section 58 which has a threaded opening 82 with an internal thread that matches the external thread of screw section 57. Socket section 58 projects visibly away from the rest of lower part 55. Upper part 56 has a passthrough opening 59. The individual components of carriage 42 and 44 now cooperate as follows. Upper part 56 may be fastened to lower part 66 with the aid of socket element 54, for which screwing section 57 passes through passthrough opening 59 and is screwed into socket section 58. In the assembled state, lower part 55 is arranged on an underside 60 of the respective guide wall 50 or 51 facing towards the inner side 23 of outer doorplate 16, which underside is facing away from the observer in
According to
According to
According to
It is evident that the common pin passthrough opening 67 equipped with screen 68 may also be configured for more than two separate relative positions, particularly for all predefined relative positions between the associated screw-in opening 25, 29 and the outer doorplate 16.
Advantageously, socket section 58 is dimensioned such that it protrudes through guide opening 48 or 49 into passthrough opening 59.
According to
The door fitting 15 presented here may be adapted a range of different configurations particularly easily. All that has to be done is to loosen the threaded joint between socket element 54 and lower part 55 so that the associated carriage 42 or 44 is displaceable along the associated carriage guide 43 or 45 in the lengthwise direction of door fitting 15, in order to set the respective desired relative position between the respective screw-in opening 25 or 29 and outer doorplate 16. As soon as the desired relative position has been reached, the threaded joint between socket element 54 and lower part 55 is tightened, causing the respective carriage 42 or 44 to be fixed in place on the associated carriage guide 43 or 45.
Further components of door fitting 15 according to
