Abstract

The coupling for rotationally fixed coupling of two coaxial shafts (110,120) of an electromechanical locking system has a rotatable disc (150) which is driven by a motor (162) and which has an annular segment-form region with at least one ramp. A control pin, which is connected to one of the shafts, is spring-loaded in the direction of the annular segment-form region and by a rotation of the control disc is movable in its longitudinal direction by sliding over the ramp. Independent claims are included for the following: (1) an electromechanical locking system with the proposed coupling; and (2) a control disc knob (100) for an electromechanical locking system.

Description

The invention relates to a coupling for the rotationally fixed coupling of two coaxial shafts of an electromechanical locking system, wherein a shaft is rotatably connected to a handle and the other shaft is rotatably connected to a cam. The coupling has a control pin which is rotatably connected to one of the shafts and which is insertable into a recess of the other shaft, whereby the two shafts are rotatably coupled and a rotation of the handle on the cam is transferable.

Such a coupling of an electromechanical locking system is from the EP 0 978 611 A2 known. In the known system, the hand knob to be connected to the cam is the outside knob of a door. In the outer knob sits a receiving antenna for communication with a transponder, which replaces a usual in purely mechanical locking systems key. The outer knob is rotatably mounted on a shaft which is arranged coaxially to the cam and passes through the door. On the inside of the door control pin and motor are housed in an inner knob. The inner knob also accommodates the electronics for controlling the motor. Outside knob and inside knob serve as a handle. A disadvantage of the known construction is the required large diameter of the inner knob, which excludes an insert of the locking system in doors with a small backset, which is the distance from the cam axis to the strike plate of the door frame.

The DE 10 2005 026 910 A1 shows a lock cylinder for an electronic locking system. The lock cylinder has at each of its end faces each one freely rotatable against a cam handle. To lock or open the handles are coupled via an electromagnetically actuated rocker arm with the cam. Although such a lock cylinder is relatively cheap to produce, but it is easy to manipulate with an external magnet.

From the DE 102 35 201 B4 is a door closing system with a handle which is rotatably coupled with a cam of a lock cylinder, known. For coupling, an integrated into the handle control slide in a complementary recess of a ring on the lateral surface of the cam is seated, inserted by motor. If the spool is retracted again, the handle is freely rotatable against the cam, neither bolt nor trap can be operated.

From the DE 198 54 454 A1 is a coupling for the rotationally fixed coupling of two coaxial shafts of an electromechanical locking system known. The two shafts engage each other, wherein one of the shafts is passed through at least a portion of the other shaft. In the coupled state, a motor-driven coupling element passes through the surface of the inner of the two shafts and the inner surface of the outer of the two shafts form fit.

The invention has for its object to provide a more compact electromechanical locking system.

This object is achieved by a coupling with the features of claim 1.

The coupling has at least one control pin which is rotatably connected to one of two shafts and which is insertable into a recess of the other shaft. As a result, as known from the prior art, the two shafts rotatably coupled. What is new is that the clutch according to the invention has a rotatable control disk driven by a motor, wherein the control disk has at least one annular segment-shaped or even annular region in which there is at least one ramp. (In the context of this application, ring segment also means a closed ring.) The control pin cooperates with the ramp, ie, the control disk is rotated so the control pin slides along the ramp and the control pin is longitudinally displaced accordingly. The control pin is spring loaded in the direction of the ramp. As a result, the control pin is pushed back or forth by turning the control disc, depending on the direction of rotation. For rotationally fixed coupling of the two shafts of the control pin is inserted by a corresponding rotation of the control disk in the recess of the shaft. Of course, the wave can also have several recesses. Due to the displacement of the control pin by means of rotation of the control disk, a number of advantages are achieved: Because the control disk, which converts the rotational movements of the motor into a linear movement of the control pin, a very compact design of the locking system is possible. Compared to the solution known from the prior art, a smaller motor with be used according to lower power consumption, whereby the life of the power supply for electromechanical locking systems commonly used batteries is extended.

The ramps have the shape of wedge surfaces and act as inclined planes, in this sense these terms are interchangeable. If the control disk is rotated so that the control pin rests against the ramp, the control pin is displaced by a further rotation of the control disk depending on the direction of rotation, ie the control pin is either inserted into the recess of the corresponding shaft or pulled out by the spring again. During actuation of the handle of the control pin can not be moved out of the recess, ie in its freewheeling position, because it is loaded laterally and thereby jammed. When the operation of the handle is completed, the control pin is no longer loaded laterally, thus displaced and is pushed out of the recess by the loaded spring, if the position of the ramp permits. A decoupling of the two shafts is therefore temporally decoupled from a corresponding rotation of the control disk.
Preferably, the displacement of the control pin, so its maximum stroke, at least in the direction of the control disc limited (eg by a stop) and in the ring segment-shaped area a recess, whereby the control pin, when its longitudinal projection falls on the recess, the control disc is not affected. Thus, the control disk in the angular range in which the recess is to be rotated without the control pin grinding on the control disk. In this angular range creates no friction between the control disc and the control pin, whereby the power consumption of the engine is further reduced. The recess may for example be designed as a segment of an annular groove or as a slot in the control disk.
Preferably, the control pin has a lower part and a telescopically cooperating with the lower part of the upper part, wherein when a collapsing of the upper part and lower part of a spring is tensioned. This allows the control pin to slide over the ramp without being directly displaced, for example when the recess of the shaft into which it is to be inserted does not yet face it. Now, if one of the shaft is rotated against the other, the spring stretches the previously collapsed control pin as soon as the control pin facing the recess, ie as soon as the control pin can be inserted into the recess. This allows a control of the motor without knowing the relative positions of the two shafts. The otherwise necessary sensor and logic can be omitted. The displacement of the control pin is temporally decoupled from the control of the motor and the resulting rotation of the control disc.

Preferably, further functions, so-called auxiliary functions, such as unlocking a battery compartment or a cover can be controlled via the clutch. For this purpose, the coupling may have one or more functional pins, the or the same principle as the In this embodiment, the control disk has at least one second annular segment-shaped region with at least one ramp and the functional journal is by a rotation of the control disk slidably displaceable in the longitudinal direction over the ramp of the further region. The functional pin may be spring-loaded in the direction of the second ring segment-shaped area. The advantage of controlling auxiliary functions via the clutch is that safety-related auxiliary functions, such as disassembly of the clutch or handle, are monitored by the control electronics of the locking system and only possible to be released by the electronics controlling the engine. As a result, only the person in possession of a corresponding authorization, for example a corresponding transponder, can use the respective auxiliary function.

As the longitudinal displacement of the control pin and the longitudinal displacement of the functional pin in the direction of the control disk is preferably limited and in the functional journal controlling ring segment-shaped area is preferably a recess, whereby the functional pin, when its longitudinal projection falls on the recess, the control disc is not affected. This also serves to minimize the power consumption of the engine.

The functional pin can be a lifting ring. As a result, a triggering of the corresponding auxiliary function is independent from the position of the two shafts, or the lifting ring possible. Such a lifting ring may preferably have three pin extensions on its side facing the control disk, each of which cooperates with one of the number of pin extensions, in this case preferably three congruent ramps of an annular region of the control disk, so that the lifting ring is preferably displaced parallel to the control disk. Likewise, in the coupling ring preferably three parallel to the control disk axis, longitudinally displaceable transmission pins which slide for longitudinal displacement as the control pin over a corresponding number of ramps of the control disk. The control pins are preferably each spring-loaded in the direction of the control disk. Alternatively or additionally, the lifting ring can be spring-loaded in the same direction.

The functional pin may have a lower part and a telescopically cooperating upper part with the lower part, wherein when a collapsing of the upper part and lower part of a spring is tensioned. As a result, as in the corresponding embodiment (see above) of the control pin, a displacement of the functional pin is temporally decoupled from the rotation of the control disk.

An auxiliary function may be the disassembly of a module receiving the coupling. Thus, a longitudinal displacement of the functional journal, e.g. via an additional pin, release a catch that secures the module against disassembly.

An auxiliary function can also be the opening of a cover, for example a battery compartment and / or a housing.

This can be done as previously described by releasing a catch. Similarly, a cover can also be unlocked by releasing a locking pin, i. a functional pin may have a position in which it blocks the locking pin and also have a position in which it allows a displacement of the locking pin, for example, by releasing a channel or other recess. The locking pin may be spring loaded. Alternatively or additionally, the locking pin may be magnetic, e.g. he may have a recess in which a magnet is inserted and fixed. Then, a force may be exerted on the locking pin by a magnet applied to it or by turning on an electromagnet which displaces the pin, e.g. from a locking position into an unlocking position and by reversing the polarity of the magnet from the unlocked position into a locking position.

The control pin and / or the functional pin preferably have a roller at its end which slides over the ramp, for example in the form of a ball bearing or a ball. As a result, the sliding friction of the respective pin is reduced on the control disk. As a result, the engine has a lower power consumption.

Preferably, the control disk has a further recess, which is penetrated by a shaft having at least one pinion, wherein the pinion meshes with the control disk, preferably the inner edge of the recess. This results in a particularly compact coupling.

On the shaft, a second pinion can sit, which meshes with a worm of the shaft of the engine. As a result, the control disk is blocked, even if no voltage is applied to the motor.

The coupling is preferably received in a control disk knob serving as a handle.

Views of a control disc.

The locking system in Fig. 1a has a commercial lock cylinder 50 with a cam 51 for actuating a locking bolt, not shown, a door, not shown (see. Fig. 1b ). On the outside of the lock cylinder 50 is an outer knob 20 with a door side slotted outer knob cap 21, the door side is braced against an undercut of an outer shaft 30 with a clamping ring 22 and serves as a handle. The clamping ring 22 is screwed by screws such as 24 with the outer shaft 30. The outer shaft 30 has a stepped axial bore in which a hollow central shaft 40 rotatably seated. The central shaft 40 is in turn rotatably connected to a likewise hollow clutch shaft 110 of a located on the inside of the door Steuerscheibenknus 100. The control dial knob 100 includes a knob shaft 120 which is rotatably connected to the lock bit 51. The knob shaft 120 has a stepped axial recess 121 in which the coupling shaft 110 is mounted with a needle bearing 130 and a ball bearing 131. For coupling clutch shaft 110 and knob shaft 120, the clutch shaft 110 is non-rotatable with a coupling ring 140 connected. The coupling ring in turn is rotatably connected to a mounting plate 160, which (not shown) and a motor 162 holds a door-side control electronics. Between the mounting plate 160 and the coupling ring 140 is a gap in which a control disk 150 is rotatably mounted. The attached to the mounting plate 160 motor 162 driven by the control electronics drives the control disk 150 at. By a rotation of the control disk 150 coupling ring 140 and knob shaft 120 are rotatably coupled with each other and thus clutch shaft 110 and knob shaft 120 rotatably connected to each other. As a result, a rotationally fixed connection between the outer knob 20 and the lock bit 51 is produced. The door is thus locked and unlocked from the outside.

From inside the door can be locked and unlocked by turning the knob shaft 120. For this sits in the fully assembled state on the knob shaft 120 designed as a cover, removable cap, which is rotatably connected to the knob shaft 120. A corresponding cap is in Fig. 4 shown (reference numeral 101).

The position of the control disk 150 is usually controlled by a transponder (not shown), which communicates with a receiving electronics, not shown, located in the outer knob. Through the stepped bore 31 of the outer shaft, a cable to a seated in the axial bore of the central shaft 40 contact part 42 can be performed. The contact part is electrically connected to a coil spring 43. For isolation between the contact part 42 and the coil spring 43 on the one hand and the center shaft 40 on the other hand sits in the axial recess of the central shaft 40, an insulating sleeve 44. At the steuerscheibenknaufseitigen end of the coil spring 43, a further wire can be secured by an axial bore 111 of the coupling shaft 110 to the door inside the control electronics (not shown), which is attached to the mounting plate 160, is guided. The coupling shaft 110, the center shaft 40 and the outer shaft 30 are made of metal and serve as a return line.

The supervision in FIG. 2a shows the motor 162, on the shaft of a worm 163 sits, which in turn meshes with a pinion 164 and thereby drives a shaft 165. The shaft 165 is mounted on the mounting plate 160 and passes through this and the control disk 150 (FIG. Fig. 2b ). On the door-side end of the shaft 165 is seated a further pinion 166, which meshes with a radially inwardly facing toothing of the control disk 150. Thus, a rotation of the motor shaft in a rotation of the control disk 150, which is coaxial with the lock bit 51 (FIG. Fig. 1b ) is implemented.

The knob shaft 120 has recesses such as the recess 125 (FIG. Fig. 2b ) into which a control pin ( Fig. 2c ) can be inserted. Fig. 2b shows the control pin 145 in its freewheeling position. The control pin 175 includes a pin top 175.1 and a pin bottom 175.2. Top pin 175.1 and pin base 175.2 are telescopically displaced against each other, with one not shown spring pin top 175.1 and pin base 175.2 apart. The control pin 175 is seated in a stepped recess of the coupling ring. At the stage, the control pin 175 is supported via a further spring, not shown. For this purpose, the spigot 175.2 has on its lateral surface an annular projection.

If the control disk 150 is rotated into its driving position, then the pin upper part 175.1 is moved by means of ramp 151 (cf. Fig. 6 ) of the control disk 150 telescoped against the spring in the spigot 175.2. Due to the spring tension, the journal lower part 175.2 is displaced in the direction of the knob shaft 120. In the in Fig. 2c shown relative position of control pin 175 to knob shaft 120, the control pin is not inserted into the recess 125. This becomes possible only when, via a rotation of the outer knob 20, the control pin 175 is also rotated, which retracts into the recess 125 and thus reaches its driving position as soon as the recess 125 is opposite it. External knob 20 and cam 51 are now rotatably coupled.

In addition, the control disk 150 controls the axial displacement of a seated in a recess of the coupling ring 140 functional pin in the form of a lifting ring 178 (see. Fig. 2b, 2c, 2d . 3a and 3b ). The cam ring 178 has on its lateral surface four approximately semi-cylindrical recesses 178.2, which together with complementary recesses 148 of the coupling ring 140 form four cylindrical recesses. In the cylindrical recesses each seated with a screw, not shown, biased spring (not shown) which the cam 178 in its seat 148, which is an annular recess of the coupling ring 140, press and thus bias in the direction of the control disk 150. The cam ring 178 has on its side facing the control disk three lifting pins as 178.1. By a rotation of the control disk 150, the lifting pins slide like 178.1 on ramps 153 (see. Fig. 6 ) of the control disk 150 and the cam ring 178 is pushed out of the coupling ring. Accordingly, the knob shaft 120 has a complementary to the cam ring 178 annular recess 128. In the recess 128 opens the head of a disassembly pin 172 which is axially displaceable in a channel-shaped recess 122 of the knob shaft 120 ( Fig. 2d ). Upon displacement of the lifting ring presses this on the head of the disassembly pin 172 and takes him away. The cam ring 178 can be pushed out of the coupling ring 140 into the annular recess until the disassembly pin 172 bears against the side wall of a fastening groove 123 lying opposite it. If the knob shaft 120 is rotated in this position of the disassembly pin 172, a spring-loaded catch (not shown) of the lock cylinder 50 is raised by the disassembly pin 172 over the edge of the mounting groove 123, whereby the control dial knob 100 can be detached from the lock cylinder, ie disassembled. To mount the Steuerscheibenknauf 100, the control disk 150 is rotated back accordingly, whereby the spring-loaded cam ring 178 is pressed into its seat 148, so that also spring-loaded Disassembly pin 172, the mounting groove 123 releases again. If now the purchase module 100 is inserted into the lock cylinder, then the catch can engage in the attachment groove 123 and fixes the control disk knob 100 axially on the lock cylinder 50.

In a further recess 126 of the knob shaft 120 sits an axially displaceable in the recess 126 another functional pin in the form of a spring-loaded in the direction of the control disk 150 pin 176 with an annular projection 176.1 on its lateral surface. The position of the pin 176 is like the position of the disassembly pin 172 controlled by moving the cam ring 178, ie ultimately by rotation of the control disk 150. In the in Fig. 2b shown position, the bolt 176 blocks a locking pin 179, ie it prevents its axial displacement. Radially outward, the locking pin 179 has a recess in which a magnet (not shown) is glued. Now, if the cam ring 178 is advanced by rotation of the control disk 150, the pin 176 is also axially displaced in the direction of the locking bit 51 against the force of a spring, not shown. As a result, the locking pin 179 can be displaced in the direction of the coupling shaft 110 by means of a further magnet brought in from the outside to the first magnet. A cap with a recess (not shown here, cf. Fig. 4 there reference numeral 101) for the locking pin 179 can now be solved by the knob shaft 120 and thus of the Steuerscheibenknauf 100. The placing of the cap on the knob shaft 120 takes place at the same position of the control disk 150, ie the locking pin 179, can now also manually (because now accessible) are moved in the direction of the axis of rotation. The cap is now placed and the locking pin 179 is moved with the other magnet in the recess provided for him in the inner surface of the Steuerscheibenknus 100. Now, by rotation of the control disk 150 of the cam ring 178 in the in Fig. 2b moved position shown, so pushes a spring the bolt 176 in the Fig. 2b shown position, so that the locking pin 179 fixed that is no longer displaceable. The cap is now fixed.

Fig. 4 shows an exploded view of another control wheel knob. As by means of the control disc knob Fig. 1 For example, with this dial knob, an outside knob such as 20 with a lock bit such as 50 (see FIG. Fig. 1b ) (identical or similar parts are identified by identical reference numerals). For this purpose, the control disk knob has a knob shaft 120 and a coupling shaft 110 which are rotatably coupled to one another by rotation of a control disk 150. As in the embodiment according to Fig. 1 is moved by the rotation of the control disk 150, a control pin 175. In contrast to the embodiment according to Fig. 1 Here is the control pin 175 rotatably connected to the knob shaft 120 and is inserted to non-rotatable coupling of knob shaft 120 and coupling shaft 110 in a recess 115 as a thickened end 116 of the coupling shaft 110 (see. Fig. 5d ).

For disassembling the control dial Knob 110 from a lock cylinder such as 50 (FIG. Fig. 1b ) has the control disk knob 110 a disassembly pin 172 (see. Fig. 5b ), which is displaceable over a running as a cam ring 178 functional pin of the control disk 150.

Fig. 4 also shows a serving as a hand knob cap 101, which sits in the mounted state on the knob shaft 120. By mounted cap 101 are shown only boards shown as 169 control electronics, the required battery 167 together with brackets such as 168 protected from manipulation and environmental influences. The locking of the cap 101 is carried out as in the embodiment according to Fig. 1 by the interaction of the control disk 150 which moves a cam ring 178. The cam ring is seated in an annular recess 128 of the clutch shaft. In the in Fig. 5a If the cam ring further pushed into the recess 128, so the locking pin 179, which holds a magnet (not shown) by means of an externally on the Steuerscheibenknauf 100 can be moved forward further magnets are moved in the direction of the coupling shaft 110. The cap 101 is now put on and removed again.

For displacement of the lifting ring 178 sit in recesses such as 149 pins (not shown) one end of each corresponding ramp as 152 (see. Figure 6 ) slides and their other end on the coupling ring 140 facing Side of the lifting ring 178 abut. Now, if the pins are moved by a corresponding rotation of the control disk in the direction of the lifting ring, so they take the lifting ring. If the control disk is rotated back, the pins slide down the ramps 152 "spring-loaded", ie in the direction of the mounting plate 160.

Merely to show that the clutch disc in both the embodiment according to Fig. 1 as well as in the embodiment according to Fig. 4 can be used was in Fig. 4 and Fig. 5b an additional (here functionless) control pin 175b located. Fig. 5d shows the additional control pin 175b in detail. The control pin 175b has at its on the ramp 151 of the control disk 150 sliding end of a roller 175.3 to reduce the friction between the control pin 175 and the control disk.

The control disk is seated as in the embodiment Fig. 1 rotatably between a mounting plate 160 and a coupling ring 140th Fig. 6a to Fig. 6c show various views of the control disk 150. This control disk is for the embodiment according to Fig. 1 as well as for the embodiment according to Figure 4 usable. To move the control pin 175 to Fig. 1 the control disk 150 has a first ramp 151 (see FIG. Fig. 2b ). If the control disk by a motor 162 (see. Fig. 2 ) so the control pin 175 slides over the ramp 151 and is thereby displaced axially. Accordingly, the cam ring 179 is displaced by three ramps 152. Another ramp 153 serves to displace the control pin 175 of the embodiment according to Fig. 4 , To the ramps 151, 152 and 153 is followed in each case by a ring-segment-shaped recess 154, 155 or 156, so that the corresponding pin (control pin 175 or lifting ring 179) does not rub with the control disk 150 if the function corresponding to the pin (coupling of the shafts, Unlocking the cap, disassembly) is not needed. The ramps 151 and 153 for the control pin 175 are opposed to the ramps 152. As a result, depending on the direction of rotation of the control disk from a neutral position, the desired function is activated, ie a clockwise rotation (relative to Fig. 6a ) leads to a rotationally fixed coupling of clutch shaft 110 and knob shaft 120 and a counterclockwise rotation allows the disassembly of the cap 101 and the control disc knob 100th
