Lock

The invention relates to a lock according to the preamble of claim 1.

EP-A-200 919 discloses an electrically controlled door lock which can be locked by means of a profile-closing cylinder held in a correspondingly shaped insertion opening of its lock housing. The profile cylinder has, as usual, an axially oriented key channel 10 in its cylinder part for receiving the key, and a tongue protrudes radially from the cylinder part. An electronic control switch is included in the lock housing, which is connected to a reading device located in the profile cylinder via a plurality of electrical contact means. The reader detects control information of the key, for example electronic lock codings, which supplement the mechanical lock codings of the key to increase the closing security.

In connection with the door lock known from EP-A-200 912, the profile cylinder is held in the recess by means of a collar screw screwed into the tongue-20 in the insertion opening of the lock housing. In order to prevent the connection between the profile cylinder reader and the electronic connection of the lock housing from being separately manufactured and disassembled during installation and disassembly of the profile cylinder, the contact members on the lock housing side are arranged transversely to the profile cylinder tongue and can be gripped. like a drive device with a collar screw transverse to the tongue of the profile cylinder. The contact elements of the tensioning strap, which can be gripped with the counter contacts 30 by the profile cylinder, are arranged on the side of the tensioning strap away from the collar screw together with an additional centering bolt fixed to the tensioning strap. In order to fasten the profile cylinder to the insertion opening of the lock housing 35, a collar screw is screwed towards the profile cylinder, whereby due to the movement of the screw the centering bolt and the contact members also approach the profile cylinder.

In the known door lock, the profile cylinder is fastened only by means of a collar screw and a centering bolt fitted opposite the clamping bracket. Since the insertion opening of the lock housing surrounds the profile cylinder with a tolerance interval that allows the tilting movements of the profile cylinder, alignment errors can occur in connection with the known lock between the electrical contact members of the Kiris-10 bar and the corresponding counter-contact members of the profile cylinder. Especially with a relatively large number of contact members to be connected, the installation of the profile cylinder can thus become difficult or even impossible. In addition, there is a risk 15 that the contact elements, which are not in line with each other, are damaged when the profile cylinder is fastened.

The object of the invention is to improve the centering of the profile cylinder with respect to electrical contact members which engage automatically in connection with the locking of the profile cylinder 20.

According to the invention, this object is solved in connection with a lock having the features of the preamble of claim 1 by means of the features given in the features of claim 1. In connection with such a lock, the contact members to be engaged with the counter-contact members of the profile cylinder and at least one locking member engageable with the counter-member of the profile cylinder are arranged transversely to the profile-30 cylinder on the slider as the contact members come into contact with their respective counter-contact members. In this way, alignment errors of the kos-35 organs are avoided.

In a first embodiment of the invention, according to claim 2, it is provided in a simple manner that the contact members and the latch member are arranged on the slide to be movable relative to each other.

In the lock known from DE-A-200 912, the profile cylinder is clamped between two tips which allow the profile cylinder to tilt about its axis within the dimensioning tolerances of the insertion opening of the lu housing. This tilt tolerance increases the alignment error of the contact members. In a preferred embodiment according to claim 3, the lock housing comprises a bearing bracket into which the tongue of the profile cylinder is firmly inserted. The slide, in turn, is displaced guided by a bearing bracket, so that the tolerances between the contact members of the slide and the counter-contact members of the profile cylinder can be considerably reduced. The bearing bracket may optionally be adjustably connected to the lock housing in order to compensate for misalignment of the profile cylinder with respect to, for example, door fittings or the like, without this affecting the tolerances of the contact members.

To guide the slide with the bearing bracket, these parts may have correspondingly shaped sliding surfaces. The space requirement of the component is particularly small when the slide is controlled by at least one control bolt 25 projecting from the bearing bracket. To ensure torque, the slide controlled by the control bolt may be guided on the walls of the lock housing. Since this operation increases the tolerances in the individual case, several mutually parallel control bolts can be fitted. In a particularly simple manner, however, a precise, torque-ensuring control can be achieved by the measures of claim 4, since in this case the latch member made as a latch bolt is used at the same time to secure the torsion of the slider.

It would be conceivable that the contact members of the latch member and the slider may be brought into contact with the profile cylinder by means of separate and successive actuating members. The embodiment according to claim 5 is solved by a single operating element. The latch bolt made as a latch member of this embodiment is displaceably guided on the slide and is biased by a spring in the direction of the locking hole fitted to the profile cylinder. The spring determines the gripping load at which the latch bolt initially secures the profile cylinder, while the slider and preferably the contact members fixed to it are then introduced into the profile cylinder. Claim 6 includes an improvement of this embodiment, since then the slide does not have to include a profile cylinder.

The biasing force exerted by the spring on the latch bolt may in individual cases be too small to permanently fasten the profile cylinder to the lock housing. In the embodiment according to claim 7, one of the slides' responses is responsible for the latch bolt protrudingly into the locking hole of the profile cylinder, so that this can no longer be pulled out of the insertion opening of the lock housing 20. When a disc spring package according to claim 8 is used as a spring, the compressed package of its block length can be used as an end stop.

According to claim 9, the latch bolt is expediently guided in a slide that rotates about its axis. This has the particular advantage that it is not possible to transfer torque from the slide to the profile cylinder at the end stage of the slider adjustment movement, which could cause the profile cylinder to tilt and correspondingly lead to misalignment of the contact members.

Further improvement of the centering is achieved by the embodiment according to claim 10. The centering pin located opposite the latch bolt already takes care of pre-centering when inserting the profile cylinder, even before the latch bolt fitted to the slider engages the profile-35 auxiliary cylinder.

* 832 <> 5

The latter improvement is also used by another embodiment of the invention (claim 11), in which at least two spaced-apart latch members 5 are fixed to the slide in a displaced direction in the direction of travel, corresponding to which locking holes are arranged on the profile cylinder so that the latch bolts protrude into the locking holes. upon attachment to the lock housing before the contact members come into contact with the mating contact members 10. The locking bolts take care of pre-centering the slider and the profile cylinder transversely to the insertion direction of the contact members. The actual attachment of the profile cylinder to the lock housing insertion is provided by the abutment surface of the slider, by means of which the slider pressed against the profile cylinder 15 presses on the profile cylinder, e.g. its tongue, and presses into the lock housing insertion opening.

Latch bolts protruding into the locking holes of the profile cylinder secure the profile cylinder-20 clamped by the slider against being pulled out of the insertion hole. The slide supports at least one, preferably in the direction of rotation, two guide members which are movably guided in the guide recesses of the bearing bracket attached to the lock housing on the side of the slide facing away from the profile cylinder. In this way, not only can a very precise control of the slider in the lock housing be achieved, but also a particularly stable fastening of the profile cylinder against being pulled out of the lock housing. The guide members can be made, for example, as extensions of the latch bolts, or they can be, for example, sides formed on a slide.

In order to equalize the setting tolerances of the slider, the contact members and the counter-contact members are preferably plug contacts. Such contacts usually consist of a pin portion and a radially resilient core portion 35 which presses against the pin portion. Although the 6-832 ° portion of the sleeve is normally relatively durable, the pins may bend or become dirty due to improper handling. In a preferred embodiment, the pin parts are therefore arranged in a shield inside the profile cylinder. It is understood that the pin portions cannot be protruded from the profile cylinder so that the cylinder can be inserted into the lu housing.

The slide can be operated by means of an eccentric or a lever or the like. However, for the sake of simplicity, a spindle drive device is shown according to claim 13, the threaded spindle of which can be formed, for example, axially by a collar screw fixed axially to the cover rail of the lock. However, the collar screw does not conventionally pierce the tongue of the profile cylinder, but terminates at a distance therefrom.

The invention is particularly suitable for use in connection with a door lock used with an electric motor, as proposed in unpublished German patent application 4,742,153.0. With this door lock, the electric-20 motor pulls the bogie in and pushes it out. The electric motor is connected for both directions of movement of the bogie via a transmission mechanism to a crank device which, when the bogie is retracted, also retracts the locking tongue. Incidentally, the locking tongue can also be retracted manually by means of the drive wheel of the button, regardless of the use of the electric motor. The latch switch proposed in said patent application is made as a latch-30 switch comprising a pivotally mounted, spring-loaded latch. However, the construction costs of the proposed latch switch are relatively high because several individual parts have to be riveted and connected to each other.

Compared to conventional mechanically and manually openable locks, the electric motor-operated door lock proposed in patent application 3 742 153.0 contains a number of additional components, so that the compact construction of the components is particularly important. In connection with the door lock proposed in patent application 3 742 153.0, the tooth-5 rod tooth converts the rotational movement of the electric motor into a propagating movement. The rack-and-pinion teeth are not arranged immediately on the bogie, but on a guide part which moves transversely to the movement of the bogie and moves with the lock housing. For both directions of movement 10 of the bogie, the guide part is connected to the bogie via oblique pushing surfaces and can be moved past the position corresponding to the retracted end position of the bogie to engage the locking tongue via the torsional response in the retraction direction. For the retraction movement of the locking tongue, the bogie moves during the working movement of the bogie only. The rack-and-pinion toothing travels transversely to the bias retracting motion portion of the lock tongue.

According to a further aspect of the invention, in order to reduce the construction space required by the transmission mechanism, the rack-toothing portions for bogie movement and the locking tongue movement are arranged to coincide with each other by a large portion of the toothing. Thanks to this simple operation, the reduction gear can be increased, so more power is available to control the lock tongue.

An exemplary embodiment of the invention is explained in more detail below in connection with the drawing. In this case, Fig. 30 shows: Fig. 1 a side view of the recessed lock of a door operated by an electric motor with the bar extended and the locking tongue extended, the second side wall being removed for the sake of clarity; Fig. 2 is a partial sectional view of the door lock taken along line 11-11 of Fig. 1; Fig. 3 is a side view of the door lock of Fig. 1 with the bar retracted and the lock tongue extended; Fig. 4 is a side view of the door lock of Fig. 1 with the bar retracted and the lock tongue retracted by the motor; Fig. 5 is a side view of the door lock of Fig. 1 in connection with manual opening; Fig. 6 is a partial sectional view of the profile cylinder of the door lock according to Fig. 1 and the area of its fastening members; Fig. 7 is a side view of the door lock overload switch of Fig. 1 in a connected state; Fig. 8 is a sectional view of the overload switch taken along line VIII-VIII of Fig. 7; Fig. 9 is a side view of the overload switch of Fig. 7 in the disconnected state and Fig. 10 is a sectional view of the overload switch taken along line X-X of Fig. 9; Fig. 11 is a partial sectional view of the profile cylinder and its fastening members in connection with a modification of the door lock according to Fig. 1, taken along line XI-XI in Fig. 12, and Fig. 12 is a sectional view taken along line XII-XII in Fig. 11. 25 seen along.

Figures 1 and 2 show a door countersunk lock comprising a lock housing 7 delimited by side wall plates 1, 3 and a cover rail 5 arranged on a narrow side. The lock housing 7 has a locking tongue 9 movably guided at right angles to the cover rail 5, the end 11 of which protrudes through the cover rail 5 and whose arm 13 is guided by a pin 17 fixed to the housing and projecting into the longitudinal hole 15 of the arm 13. The longitudinal hole 15 is fitted with screw compression springs 19, which are supported on the one hand on the pin 17 35 and on the other hand on the end closer to the tongue end of the longitudinal hole 15 but on the end and the locking tongue 9 is biased in the ejection direction. By means of the drive wheel 21 of the button mounted on the pivotable lock housing 7, the locking tongue 9 can be retracted against the screw compression spring 19 by means of a button 5 arranged in more detail, arranged inside the door. For this purpose, the drive wheel 12 of the button has a finger 23 which, via the shoulder 25 of the tongue arm 13, pulls the locking tongue 9 in the retraction direction. The return spring 27, which is made as a torsion coil spring, holds the button on the drive wheel 21 10 in the resting position releasing the locking tongue 9. The return spring 27 surrounds the drive wheel 21 of the button coaxially and does not require much more space than the drive wheel 21 itself. Thus, space remains in the lock housing 7 for additional electronic components.

In the lock housing 7, at a distance from the lock tongue 9, a bogie 29 is displaced at right angles to the cover rail 5, the bogie end 31 of which protrudes through a non-detailed opening of the cover rail 5 and which is guided between two pins 33, 35 attached to the housing. The bar 29 is retracted and pushed out by an electric motor 37, which also, independently of the use of the button, pulls in the locking tongue 9. The electric motor 37 is controlled by a control switch not shown in more detail, such as that described in DE-A3 606 25 620. The control is operated by an electronically coded key, not shown in more detail here, and is connected to a profile cylinder 38 adapted for this purpose. the key channel 39 to the reading device 40 which reads the data of the key and generates the electrical signals, respectively.

The electric motor 37 drives, by means of a gear transmission mechanism 41, a plate-like guide part 43 which is rectangularly displaced in a rectilinear manner between the inner side of the cover rail 5 and the pins 33, 35 with respect to both the locking tongue 9 and the bogie 29.

3 8 3 Γ 9 ίο

The transmission mechanism 41 arranged between the lock tongue 9 and the bogie 29 comprises a coil 45 on the drive shaft of the electric motor 37, which is toothed with a side wheel 49 mounted on the side wall plate and a support plate 5 47 mounted on the housing on the one hand. The helical gear 49 drives a gear 53 via a coaxially arranged gear 51, which is connected to a small gear 10 via an overload switch 55 which transmits only a predetermined torque, which will be described in more detail below. The small gear 57 engages parallel to the cover rail 5, i.e. to the rack teeth 59 using the guide portion 43 parallel to the direction of travel of the guide member 43. 61 to which a pin 63 fitted to the shaft 29 engages.

Fig. 1 shows the door lock in the latch position, i.e. with the latches 29 completely extended from the lock housing 7, the guide part 43 being set in its position remote from the lock tongue 9. Fig. 3 shows the door lock with the bolt 29 retracted, but with the lock tongue 9 extended, the electric motor 37 bringing the guide part 43 in the vicinity of the lock tongue 9 in connection with the retraction of the bogie 29. As shown in Figs. 1 and 3, the slot 61 guiding the movement of the bogie 29 has a substantially Z-shape, with the end portions 67, 69 perpendicular to the direction of movement of the bogie 29 associated with the ends of the slit 61 facing both the direction of movement of the bogie 29 and the guide portion 43. The end portions 67, 69 receive the pin 63 in the fully extended and fully retracted position of the bogie 29 and thus ensure the mandatory retraction and retraction of the bogie 29. 35 ejections.

11 9 8 32 9

The control part 43 also controls the retraction movement of the locking tongue 9. In the vicinity of the locking tongue 9, the guide part 43 supports a finger 75 which, when the bogie 29 is retracted, goes into the recess of the tongue arm 13 delimited by the shoulder 77.

The rack and pinion 59 extends over a rectilinear region parallel to the cover rail 5 required for bogie movement and is bent through the concave toothing region 78 in the toothing area where the bogie end 31 pin 63 enters the end portion 69 of the slot 61, bent 10 the small gear 57 turns the guide part 43 around the pin 63 in the figures clockwise. The finger 75 then, as shown in Fig. 4, takes the locking tongue 9 in the retraction direction. Figure 4 shows the door lock 15 with the bolt 29 retracted by the electric motor and the locking tongue 9 retracted with the electric motor. In order to enable the pivoting movement of the guide part 43, the pins 33, 35 guiding the shaft arm 32 are arranged so that the guide part 43 can swing between the pins 33, 63 for the pivoting movement. The angle adjacent to the Pei-20 rail is provided with a chamfer 79. Since the rack 59 travels 59 in the arcuate region in a concave manner, i.e. on the outside, the result is a lower gear ratio compared to the inside, which reduces the space requirement of the transmission mechanism 41.

25 In the event of an emergency, the door lock can also be opened manually, independently of the electric motor, by using the door button, even when the door 29 is extended (panic function). As shown in Fig. 5, the knob is turned on the inside of the door, i.e. on the secured side of the door, by twisting the button drive wheel, so that the finger 23 pulls the locking tongue into the tongue 9 through the shoulder 25 fitted to the arm 13. At the same time, the projection 81 formed on the button drive wheel 21 moves the guide part 43 in the opening direction of the bogie 29. The projection 81 then strikes the projection 83 of the guide part 43 35, for example against the pin 12 38329 riveted to the guide part 43. The forced movement of the guide part 43 is transmitted through the beveled surfaces of the slot 61 and the pin 63 to the shaft 29, which thus protrudes into its retracted position. The overload switch 55 arranged on the slope is exceeded during manual operation of the control part 43 and engages the self-braking coil 45. The overload switch 55 also protects the electric motor 37 and the transmission 43 during electric operation of the door lock. The details of the overload switch 10 will be explained below in connection with Figures 7-10.

The electric motor 37 is controlled by a non-detailed electronic connection arranged on a switch plate 85 arranged on the side of the mechanical components of the door lock between the side walls 1, 3 of the lock-15 housing 7. The electronic connection is connected to the reading device 40 of the profile cylinder 38 via several, for example six, wires. The profile cylinder 38 in the mutually shaped insertion opening 87 of the two side parts 1, 3 is connected to the electronic connection via a plug connection 89 in these inlet lines 20. Fig. 6 shows details of the plug connection 89 and the associated retaining device 91 which releasably holds the profile cylinder 38 in the insertion opening 87. In contrast to Figs. 1-5, however, the retaining device 91 25 is shown in a position which allows the profile cylinder 38 to be removed. The retaining device 91 comprises a bearing bracket 93 held by a lock housing 7, which has a recess 95 aligned with the insertion opening 87, into which the tongue 99 projecting from the cylinder part 97 of the profile cylinder enters. The recess 95 surrounds the tongue 99 both from the side and along its longitudinal edge remote from the cylinder part 97 and ensures that the profile cylinder 38 is centered with respect to the bearing bracket 93 and not with a slight oversize by the edges of the inlet 35 surrounding the profile cylinder. The guide pin 101 attached to the bearing bracket 93 has a slidably controlled slide 103 which supports a strip with a support 105 with a plurality of plug sleeves 107 of the plug connection 89 distributed along the profile cylinder 38. The mating elements 5 of the plug connection 89 are completely fitted as contact pins 109 inside the recess 99 of the tab 99 of the profile cylinder 38 for the plug-in tape 111. The tab 99 thus protects the sensitive contact pins 109 from damage and contamination.

The slider 103 can be moved on the cover rail 5 by means of a support-10 bearing 113 rotatably but axially held by a threaded mandrel 115 along a guide pin 101, the threaded pin 115 being screwed into a threaded sleeve 117 which is torsionally secured to the slide 13 by a locking pin 119. supports, in addition to the plug sleeves 107, a retaining pin 121 corresponding to the tongue 99 of the profile cylinder 38 with a locking hole 123 arranged on the contact pins 109. a disc spring package 131 is tensioned between the shoulder 129, which biases the sal bolt 121 in the direction of the locking hole 123. The end of the latch pin 121 adjacent the locking hole 123 is inserted into the guide hole 133 of the bearing bracket 25 93.

The guide pin 101 and the latch pin 121 guide the slide 103 in a torsionally secure manner and centrally with respect to the bearing bracket. Since the distance between the locking hole 123 and the adjacent end of the latch pin 121 in the release position 30 of the profile cylinder 38 is less than the distance between the plug sleeves 107 and the contact pins 109, the latch 121 locks to the profile cylinder 38 before the plug connection 89 is connected. The latch pin 121 thus locks the plug sleeves 107 and the contact pins 109 of the profile cylinder 38 in a centrally aligned position before the contact ^ 83: ° 14 engages. Thus, damage to the plug sleeves 107 and the contact pins 109 due to straightening errors is avoided.

The retaining force of the latch pin 121 is initially determined by the prestress of the disc-5 spring package. In the individual case, the prestress may be too small to secure the profile cylinder 38 in use against being pulled out. To accomplish this, the block length of the fully compressed disc spring package 131 is selected so that the latch pin 121 in the end position of the slider 10 103 non-stop in the locking hole 123 and is supported against the extension 129 of the threaded sleeve 117 by the fully compressed disc spring package 131. In the end position of the slider 103, the plug connection 89 is connected, whereby the length of the contact pins 109 is dimensioned so that they can compensate for the movement tolerances of the sleeves.

On the side opposite the latch pin 121, in the bore 135 of the bearing bracket 93 coaxial with respect to the latch pin 121, a ball tip 137 is provided with a centering pin 139 guided by a compression spring 141 20 prestressed into the locking hole 143 of the tongue 99. wherein the center tin 139 corresponds to the pre-center of the profile cylinder 38 with respect to the bearing bracket 93 and thus to the pre-center of the locking hole 25 with respect to the latch pin 121.

Figures 7-10 show details of the overload switch 55 described in connection with Figures 1-5.

The overload switch 55 is made as a latch switch and engages the gear 53 on a common shaft 145 with a small gear 57 rotating relative to the gear-53 gear 53. The side of the gear 53 facing the gear 57 has a recess 147 radially displaced radially with respect to the shaft 145 in a recess 147 having a shaft 145, the retaining projection is radially projecting towards the gear 57, the retaining projection 151 overlaps the circumference of a circular plate 153, which circular plate is torsionally connected to the gear 57 via a pin 154 and secures the slider 149 axially in the recess 147. a circumferential retaining notch 155 into which the slider 149 retaining projection 151 is biased by the spring 157. The protrusion 151 and the notch 155 have oblique edge edges when viewed in the circumferential direction, so that the protrusion 151 connecting the gear 53 to the small gear 57 retracts when a predetermined torque-10 torque is exceeded out of the notch 155 against the force of the spring 157 and the overload coupling disengages. Figures 7 and 8 show a locked overload switch, while the disconnected state is shown in Figures 9 and 10.

As further shown in Figures 7 and 8, the slide 15 149 has a longitudinal hole 159 through which the shaft 145 passes.

The protrusion 151 is bent from the interior of the longitudinal hole towards the small gear 57, while diametrically opposite the protrusion 151 the strip 161 is bent into the radially extending chamber 163 of the gear 53. 20 The chamber 163 has a spring 157 supported on the end of the strip 161 and the shaft 145 between. The overload switch 55 is relatively simple to install and consists of only a few parts.

Figures 11 and 12 show a modification of the profile cylinder mounting which can be used instead of the profile cylinder mounting shown in Figure 6 in connection with the door lock of Figure 11. The door lock again comprises a lock housing 207 formed of side walls 201, 203 and a cover rail 205, which side walls 201, 203 have insertion openings 211 shaped to receive a profile cylinder 209 provided with an electronic reading device 201 to receive the profile shape of the profile cylinder 209. A plurality of contact pins 215 are mechanically shielded and electrically insulated from the recess 217 of the tongue 213, which extends transversely to the 16 ° profile cylindrical tab 213 extending transversely from the profile cylinder. which, in turn, are attached in isolation to a slide 221 which moves in the injection direction of the contact pins 215. The slide 221 is in turn fixed to two bolts 223 which are located parallel to each other and spaced apart from each other. in the insertion direction of the contact pins 215 and which are movably guided on the side of the slide 221 remote from the profile cylinder 209 in the bearing bracket 225 fixed to the lock housing 207. The bolts 223 pierce the slider 221 and protrude on the side facing the profile cylinder 209 in the pushing direction of the slider 221 over the sleeves 219. The portions projecting past the slider 221 15 toward the profile cylinder 209 form latch bolts 227 to which locking holes 229 are fitted in the profile cylinder tongue 213. The latch bolts 227 engage the locking holes 229 and straighten the tab 213 relative to the slider 221 before contact 21. damage to the plug contacts is reliably avoided despite the normally small clearance in the insertion holes 211 of the profile cylinder 209. Since the bolts 223 are guided for a considerable length in the bearing bracket 225, they certainly prevent violent pull-out of the profile cylinder 209. To adjust the slide 221, the bearing bracket 225 has an adjusting screw 231 accessible from the cover rail 205, but still axially secured in place by a locking pin 233. The adjusting screw 231, like the spindle drive 30, engages the threaded hole of the slider 221. The slide 221 can be moved by means of the adjusting screw 231 from the cover rail 205 towards the tongue 213 of the profile cylinder. A abutment surface 235 fitted to the slider 221 presses the profile cylinder against the edges of the insertion openings 211. However, the holding-35 force does not have to be particularly large, because the 17 ° 8 32 ° profile cylinder 209 is secured against being pulled out of the insertion openings 211 by means of bolts 223.

In a more suitable modification of the profile cylinder mounting described above, instead of the bolts 223, there are elongate guide sides in the pushing direction, which are integrally shaped on the side of the slider 221 remote from the latch bolts 227. The guide sides are guided in the grooves of the bearing bracket 225 and enclose the bearing bracket in a fork-like manner.
