Abstract:
A device for actuating a lock on a door or hinged lid, particularly for a vehicle, includes a momentary contact switch and a lock cylinder having tumblers which are transferred between a blocked position and an unblocked position by a key. In the locked position, the tumblers interact with a locking edge which is released only in the unblocked position. The travelling motion of the momentary contact switch is transferred to an entry element of the lock only in the unblocked position. The lock cylinder is arranged in a manner that prevents it from twisting, and the blocking edge is configured to move transversely in relation to the tumblers. This transverse motion is caused by the traveling motion of the momentary contact switch. The blocked position of the tumblers prevents the transverse movement of the blocking edge. The traveling motion of the momentary contact switch is then only transferred to the lock when the transverse motion of the blocking edge is possible.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention pertains to a device for actuating a lock on a door or hinged lid. The lock is actuated by a manually toggled push button, which in certain situations acts on the input element of the lock, which is mounted on the door. In addition, the device has a lock cylinder, which can be actuated by a key assigned to it. By means of the key, the tumblers in the lock cylinder are moved from their normal blocking position into a release position. In the blocking position, the tumblers project out from the lock cylinder and interact with a blocking edge, which is essentially parallel to an axial plane passing through the axis of the lock cylinder. In the blocked position, the toggling motion of the push button is not transmitted to the input element of the lock. This transmission cannot occur until after the key has brought the tumblers into their release position and as a result are no longer able to interact with the blocking edge. 
     2. Description of the Related Art 
     In the known device of this type (DE 197 46 381 C1), the lock cylinder itself is the toggled push button. The lock cylinder consists in this case of a cylinder core, which holds the tumblers, and a cylinder guide, in which the core can be rotated by means of the correct, inserted key. The cylinder guide has at least one blocking channel, the lateral flanks of which serve as the blocking edges. After the key has been removed, the tumblers projecting from the cylinder core are supported on the blocking edges and therefore prevent the cylinder from rotating. In this known device, the blocking edge is stationary, whereas the tumblers can be rotated relative to the edge by the rotation of the cylinder core. So that the toggling movement of the lock cylinder can act successfully on the lock, the key, which has been inserted into the cylinder core, must first rotate the cylinder core with respect to the cylinder guide. If the key is not rotated, the toggling movement of the known lock cylinder has no effect, and the toggling motion is not transmitted to the input element of the lock, located behind the lock cylinder. 
     The user of the known device must therefore understand the sequence in which the actuations must be performed, namely, the rotation of the key and the pushing-in of the lock cylinder, which acts as the push button, and perform them in the proper order. In addition, relatively complicated components are required, which allow the toggling movement of the known lock cylinder to be transmitted when the tumblers are in the release position, but which, when the tumblers are in the blocking position, either block such transmission or simply allow the cooperating components in question to move freely without effect. 
     In a device of a different type, in which the tumblers do not interact with a blocking edge located laterally next to them (DE 199 27 500 A1), it is known that a lock cylinder can be installed nonrotatably in a cylinder guide. In the normal situation, the lock cylinder is prevented from being toggled. But after the key has been inserted, a linear toggling movement is possible, as a result of which the door is unlocked. Lateral blocking edges do not scan the tumblers. 
     SUMMARY OF THE INVENTION 
     The invention is based on the task of developing a reliable device of the type mentioned above which avoids the disadvantages indicated above. This is accomplished according to the invention by the measures indicated in the characterizing, clause of claim  1 , to which the following special meaning attaches: 
     In the invention, the lock cylinder does not have to be turned by the key. It is sufficient for the correct key merely to be inserted, as a result of which the tumblers in the lock cylinder are moved out of their normal blocking position and into their release position. For this reason, the lock cylinder in the device according to the invention is installed so that it cannot rotate. In the invention, however, the blocking edge is free to move. The toggling movement of the push button is converted into a transverse movement of the blocking edge, which is oriented crosswise to an axial plane passing through the lock cylinder. This blocking edge scans the lock cylinder to determine whether or not at least one of the tumblers is still projecting or whether, as a result of the insertion of the correct key, all of the tumblers have been pulled back. That is, the presence of only a single tumbler in the blocking position is enough to prevent the transverse movement of the blocking edge. The input element of the lock is moved in the opposite direction exclusively by the transverse movement of the blocking edge. If this transverse movement does not occur, no force is exerted on the input element of the lock, and the lock is not actuated. No additional components are needed to make the toggling movement of the push button with respect to the lock effective or ineffective. The design of the invention is thus very simple. 
    
    
     The invention can be realized in various ways, and specific advantages are associated with each embodiment. The blocking edge can be part of a pivotably supported pivoting element, of a transverse thrust element, or of a combination element, which can both pivot and slide. These measures are explained in greater detail in the subclaims, in the drawings, and in the description. The drawings illustrate the invention schematically on the basis of several exemplary embodiments:

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     In the exemplary embodiment shown, the input element  40  of a lock (not shown in detail) is designed as a so-called “Bowden cable”. This Bowden cable  40  comprises a jacket  41 , which is permanently connected to a carrier  16 , which also advantageously has an axial guide  17  for a push button. Inside the Bowden jacket  40  there is a flexible core, which is hinged to the working end of a working arm  45  according to FIG. 1 or to a reversing lever  57  of the device shown in FIG. 4 a  or FIG. 6 a . In the former case, i.e., in the case of the device  10 . 1 , the working arm  45  is connected nonrotatably to a pivoting element  31 , which has a blocking edge  30  with which it scans the tumblers  21 ,  21 ′ of a lock cylinder  20 . For this purpose, as FIGS. 3 a  and  3   b  show, the pivoting element  31  is provided with a C-shaped profile  37 , the two blocking edges  30 ,  30 ′ being provided on the two sidepieces  38 ,  38 ′ of the C. The tumblers  21  are arranged in a row  23 , which simultaneously determines the axial plane through the lock cylinder  20 . 
     So that, in the first exemplary embodiment of the device  10 . 1  of FIG. 1, the lock is not destroyed after the key has been removed or the wrong key inserted by attempts to forcibly actuate  12  the push button  11  or the actuating unit  15  obtained by installing the lock cylinder  20 , a predetermined breaking point  48 , shown in FIG. 2, is provided on the working arm  45 . This point is created by a thin, tongue-shaped support point  47 . When force is applied, therefore, the tongue-shaped support point  47  will break. The tumblers  21 ,  21 ′ in the blocking position  21 . 1  according to FIG. 3 a  are thus protected from damage. 
     In the case of the device  10 . 1  of FIG. 1, the actuating unit  15  is under the force of a restoring spring  19 , which is supported at the other end on the working arm  45  and thus keeps this arm in the starting position according to FIG.  1 . The primary role of the restoring spring  19 , however, is to produce a restoring force  18  on the actuating unit  15 . End stops  43 ,  44 , possibly with a layer of elastomeric material between them, ensure that the push button  11  to be actuated assumes a defined resting position  11 . 1  with respect to the carrier  16 . 
     A more careful scanning of the release position of the tumblers is obtained in the second and third exemplary embodiments according to devices  10 . 2  and  10 . 3  of FIGS. 4 a  and  5 . Here the blocking edges  30  and/or the additonal blocking edges  30 ′(not shown in detail) are located on a thrust element  32 , which is able at first to move transversely inside the actuating unit  15  of FIG. 4 a  or inside the push button  11  of FIG.  5 . This is done by means of a link guide  50  in an adjacent control slide  34 . This link guide  50  is provided in duplicate and consists of two slit-like, slanted guide parts  52  in the control slide  34  and of two stationary slide parts  51 , which are anchored in the carrier  16  or in the axial guide  17 . To allow the toggling movement  12 , therefore, the push button  11  has longitudinal slots  54 , shown in FIG. 4 b , for the slide parts  51 . The tumblers  21  are scanned very reliably and yet carefully. It is obvious that, here, too, the thrust element  32  has a U-shaped profile  37  similar to that of the thrust element  31  of FIGS. 3 a  and  3   b.    
     FIG. 4 a  shows the position before the key  22  has been inserted. Now the blocking edge  30  is approximately parallel to the axial plane  23  and separated from it by a distance  24 . 1 . The transverse load springs  39 , in conjunction with an end stop  49  between the two parts  32 ,  34 , ensure that these components  32 ,  34  are at the maximum distance  59  from each other when in the rest position  11 . 1  of FIG. 4 a . Here, too, a restoring spring  19  provides a restoring force  18  on the actuating unit  15 . When pressure  12  is exerted on the push button  11 , the contact point  55  belonging to the thrust element does not strike the corresponding opposing contact point  56  of the associated transfer lever  57  but rather travels with no effect into a free space  64  in this lever  57 . The elastic transverse loads  39  acting between the thrust element  32  and the control slide  34  are minimal and do not impair the projecting tumblers  21 . The toggling movement  12  is transmitted via guide strips  13  from the toggle part  11  to the slide  32 . 
     According to FIG. 4 b , after the key has been inserted, it is possible for the slide  32 , during an initial phase  61  of its movement, to travel freely across the retracted tumblers  21  and for its contact point  55  to line up axially with the opposing contact point  56  of the transfer cable  57 . In the intermediate position  11 . 2  of FIG. 4 b , the distance  24 . 2  between the blocking edge  30  and the axial plane  23  has been reduced to practically zero. During the remaining phase  62  of the movement noted in FIG. 4 b , a displacement  36  occurs exclusively in a plane parallel to the axial plane. In the completely pushed-in position  11 . 3  of the actuating unit  15  of FIG. 4 b , finally, the transfer lever  57  present there arrives in the end pivot position illustrated in broken line, in which the lock in the door has been opened via the core  42  of the Bowden cable  40 . 
     The third exemplary embodiment  10 . 3  of FIG. 5 differs from that in FIG. 4 a  in that the lock cylinder  20  is not connected as in FIG. 4 a  to the push button  11  to form a structural unit  15  but rather is seated permanently in the carrier  17 . The thrust element  32 , the control slide  34 , and the transverse load springs  39  situated between them are seated in a cradle  90 , which is mounted in the axial guide  17  with freedom to move longitudinally in the direction of the toggling movement arrow  12  shown there. A push button  11  is permanently connected to the cradle  90 , and thus the two components execute the toggling movement together. The cradle  90  is under the restoring force  18  of a restoring spring  19 . The pushed-out position  11 . 1  of the push button  11  in front of the axial guide  17  is determined by the stop effect of a flange  91  or the like, which can, for example, cooperate with the inside surface of the front wall  92  of the housing. Otherwise, the way in which the device  10 . 3  functions is the same as that of the previously described device  10 . 2  according to FIGS. 4 a  and  4   b.    
     In the case of the fourth device  10 . 4  of FIGS. 6 a  and  6   b , the blocking edge  30  is again on a pivoting element  31 , which is hinged at  33  to one end of a transfer lever  57 . The transfer lever  57  is mounted permanently at  63  in the housing, and its other arm acts on the input element  40  of the lock, the input element being designed here again as a Bowden cable  40 . The pivoting element  31  has special guide means  60 . These consist in the present case of a control pin  65 , which moves along with the actuating unit  15 , and of a profiled pin guide  66  in the pivoting element  31 . The pivoting element  31  is under the action of an elastic load  75 . For this purpose, a sidepiece spring is used in the present case, one of the sidepieces of which tries to keep the blocking edge  30  of the pivoting element  31  pressed against the tumblers  21 , which are projecting outward are thus in the blocking position. In the absence of the key  22 , the starting position of the pivot element  31 , shown in solid line in FIG. 6 a , is present. When in this case the push button  11  is actuated in the direction of the arrow  12  of FIG. 6 a , the pivoting element  31  is not carried along. Although the actuating unit  15  moves along with the control pin  65  present in it in the direction of the arrow  74  in FIG. 6 a , the control pin arrives in a free-travel section  69  of the control curve  67 . During the axial movement of the lock cylinder  20 , which is carried along also, the projecting tumblers  21  slide along the blocking edge  30  of the resting actuating element  31 . The pivoting element  31  thus remains without effect. The pivoting element  31  hinged to the overload lever  57  remains at rest, and the lock is not actuated. 
     When, proceeding from FIG. 6 a , the tumblers  21  have arrived in their release position as a result of the insertion of the correct key  22 , the blocking edge  30  of the pivot element  31  is free of the tumblers  21 . Then the pivoting element  31  can, under the action of the previously mentioned spring-loading force  75 , pivot in the direction of the arrow  73  into the pivot position indicated in dash-dot line. Then the control curve  67  also arrives in the pivot position illustrated in dash-dot line in FIG. 6 a  and is located above the retracted tumblers  21 . Then, however, a driver shoulder  68 , as can be seen in FIG. 6 b , has also arrived in axial alignment with the control pin  65 , shown there in solid line. When the unit  15  is actuated in the direction of the arrow  12 , after an initial phase of the toggling movement indicated by the arrow  71  and an intermediate position  11 . 2  has been reached, the control pin  65  arrives in the position indicated in dash-dot line, where it comes into contact with the driver shoulder  68 . During the remaining phase  72 , which then follows, of the total toggling movement  70  shown in FIG. 6 b , the pivoting element  31  continues to move  74  in an essentially axial direction. The transfer lever  57  is pivoted against the action of the sidepiece spring into the working position shown in FIG. 6 b  and carries the connection point of the Bowden cable  40  along with it. The lock is actuated. 
     Whereas the pin guide  66  is designed as an opening  77  in the pivoting element  31  in the case of the device  10 . 4  according to FIG. 6 b , the pin guide is designed as a groove  78  made in the pivoting element  31  in the case of the fifth device  10 . 5  according to FIG.  7 . This groove  78  has a profile similar to that of the opening  77 , for which reason the effects are the same as those which occur in the case of the device  10 . 4 . In the case of the device  10 . 5  of FIG. 7, the transfer lever  57  is designed as an angle lever, for which reason the input element  40  of the lock can assume a different angular position than it can in the device  10 . 4 . By means of fastening means  79  such as rivets, the lock cylinder  20  is connected to the push button  11  to form a common actuating unit  15 . As can be seen from the offset cross section of FIG. 8, the control pins  65  consist of two opposing parts, between which the pivoting element  31 , designed here as a hollow body, is located. The control element  31  in FIG. 8 has two opposing pairs of grooves to correspond with the component pieces  65  of the control pin. 
     FIGS. 9 and 10 show a sixth embodiment of the device  10 . 6  according to the invention, which is the same in many respects as the device  10 . 5  of FIG.  7 . The previous description applies insofar as agreement is present. It is sufficient to discuss the differences. 
     In the case of the device  10 . 6  shown in FIGS. 9 and 10, the push button  11  of the actuating unit  15  is made up of two parts: it has a cover  80 , which serves as the contact surface  58  for the pushing actuation  12 , and a sleeve part  93  with an expanded floor section  94 . The lock cylinder  20  is supported by its end surface against the inside surface  81  of the floor section  94 . In this area, it is also possible to provide an elastomeric seal  95  for the key channel  26 . The cover  80  is designed as hinged lid and is supported at  82  in front of the floor section  94  of the sleeve  11 . The hinged lid  80  can be pivoted in the direction of the arrow  83  between the covering position  80 . 1  shown in FIG.  9  and an open position  80 . 2  shown in FIG.  10 . 
     A blocking lever  85  is able to move along with the actuating unit  15 . The hinged cover  80  has a cam  84 , which, when the cover swings  83 , pivots the blocking lever  85  between two positions  85 . 2  and  85 . 1 . When the cover  80  is moved into its open position  80 . 2  of FIG. 10, the cam  84  releases the blocking lever  85 . Then, as a result of the restoring spring  88  acting on it, the blocking lever  85  can pivot into its blocking position  85 . 1 , where it engages with a blocking shoulder  87  in the axial guide  17  of the actuating unit  15 . The toggling movement  12  of the structural unit  15  is now blocked. 
     When the hinged cover  80  is in its covering position  80 . 1  of FIG. 9, its cam  84  presses the blocking lever  85  into its unblocking position  85 . 2 , shown in FIG.  9 . Then there is no effective blocking action between the actuating unit  15  and its axial guide  17 . Now a toggling movement  12  of the actuating unit  15  is free to occur immediately, and this leads to the reverse actuation of the lock via the input element  40 , previously described several times. 
     The floor section  94  of the actuating unit  15  accepts the end of the inserted key  22 . When in its covering position  80 . 1 , the hinged cover  80  therefore extends over the exposed end of the key. Now the previously mentioned contact surface  58  of the actuating unit  15  is available to be pushed. The cover can be secured in its closed position  80 . 1  by latching means  89 , provided between the free end of the hinged cover  80  and the floor section  94  of the actuating unit  15 .
