Abstract

A closure device has a closure cylinder that acts at the same time as a push handle for actuating lock members. The closure cylinder is radially subdivided into a circumferential cylinder guide and into a central cylinder core. The cylinder core may be moved by a key between a locked and an unlocked position of rotation, but when the key is removed the cylinder core is secured by holders to the cylinder guide in a fixed manner not only in the axial direction but also in the direction of rotation. An axial spring force that acts on the cylinder guide axially movable in the cylinder housing actuates the closure cylinder as a push handle. In order to create a reliable device that cannot be forced open, the push handle is made up of two axial sections, of which only the outer section is formed by the closure cylinder whose circumferential cylinder guide is mounted so as to rotate in the cylinder housing. The inner section is in turn radially subdivided into two parts and consists on the one hand of an axial central control bolt and on the other hand of a circumferential pressure bushing. The control bolt is secured to the driver against rotation and axial movements and is mounted in the pressure bushing in a rotary but axially fixed manner. In addition, the pressure bushing is guided in the cylinder housing so as to move in the axial direction but not to rotate. An axial coupling is arranged between the control bolt and the cylinder core and the spring-loaded pressure bushing is pressed by an axial lifting profile against the cylinder guide. When the outer section of the push handle is violently turned, the lifting profile makes the inner section of the push handle run freely in an overload state in which the closure cylinder can turn freely but ineffectively.

Description

Locking device with closing cylinder actuated simultaneously with push handle for actuating lock member

The present invention refers to a locking device of the type indicated in the preamble of claim 1 relating to the closing cylinder having to perform two different functions. One function consists of a cylinder core rotatably supported in the cylinder guide being connected between a locked rotation point and an open rotation point by means of key operation. The connection movement of the cylinder core is transmitted only to the driver integrating with the lock member at the open rotation point, but not at the locked rotation point. The second function of the closing cylinder is a push handle axially squeezed in the cylinder housing by pressing a button against the spring force acting on the closing cylinder and actuating the lock member at the point of rotation of the cylinder core where the lock described above is opened. It consists of

The push handles known according to French patent 24 51 985 A1 are simply formed by a closed cylinder. The cylinder guide was rotatable but connected to the cylinder guide to fix it axially, and the driver was mounted directly on the cylinder core to fix it so that it did not rotate and the cylinder to execute the rotational connection by the key motion generated from the cylinder core. Connect axially to the core. The axial spring force lying under the push button causes it to be operated directly on the cylinder guide of the closing cylinder. Moreover, the closing cylinder could be arranged axially along its cylinder guide on the circumference for the effect of the push button, but is also guided in the cylinder housing to be fixed against rotation.

The closed cylinders of known locking devices operated by push handle handling were not antitheft. Like the rotary plate installed in the cylinder, the guide could no longer be used because the guide could be damaged by forcibly rotating the cylinder core using a strength tool. Sometimes it is not enough to replace each part of the device and a complete replacement is required.

In the locking device of the same type (DE-39 02 742 C2), the closing cylinder in the locking device is used as a push handle for operating the lock member, and the cylinder core extends by a continuous axis on the installation point of the press. When the closing cylinder is actuated by pressing, the axially moved press foot rotates a transmission lever that rotates a rotating bar leading to the lock member at the open rotation point of the closing cylinder. In this case, it is prevented by the independent blocking means of the locking device. The blocking means consists of a blocking hook which can rotate with the press foot and lock the electric lever at the locked rotation point of the cylinder core. These restraining means are arranged on the outer surface of the cylinder housing which houses the closed cylinder in which they occupy additional space. Forced rotation of the cylinder core with the tool for strength can also cause damage to structural component parts within the region of the closed cylinder as described above.

European patent (EP-0 143 087 A1) is of the same type, in which the push handles provided for actuating the lock member consist of a cylinder core actuated by a cylinder guide containing only individual parts, ie the key and the latter. Demonstrating lock. The longitudinal movement of the cylinder guide, which has been effected by crimping, can be changed longitudinally on the circumference of the fixed cylinder housing and towards the annular body acting on the lock member via a projection in the open rotation point when the push handle is actuated. Passed through the pin. There is no protection provided against the invasion of thieves.

The German patent (DE-38 27 418 C2) shows another type of locking device that is not in accordance with the preamble of claim 1. The closing cylinder is not designed with a push handle operating on the lock member during operation. Instead, the lock member is operated directly by rotating the key inserted into the cylinder core. Both cylinder cores and their cylinder guides are rotatable but supported in fixed cylinder housings to prevent them from moving axially. The rotation of the cylinder core activated by the key is directed towards the connecting bar fixed with respect to the rotation associated with the push craw and to the rotating bar integrated with the lock member tightly engaged with the connecting sleeve. It is delivered through a push craw axially connected with the cylinder core. The foregoing does not suggest the transfer of these steps to the device of the type indicated in the preamble of the claims. In particular, nothing is presented about how to prevent unwanted connection of the cylinder guide from the locked rotation point to the open rotation point without the use of a key.

It is an object of the present invention of the form as indicated in the preamble of the claim 1 that does not suffer from attempts of strength and resists forced rotation of its closed cylinder without damaging its structural component parts. To develop a compact and reliable closure device. According to the invention, this is achieved by the steps indicated in the characterizing part of claim 1, which is the meaning of the invention as described below.

In the present invention, the push handle consists of two shaft portions each divided in two radial directions. The closing cylinder thus only forms the axial outward cross section of this new push handle and has its cylinder guide at its circumference in order to be able to rotate freely in proportion to a known closed cylinder of this type which is indirectly induced in the axial direction. By the cylinder housing. Induction of the non-rotating axis of the closed cylinder in the cylinder housing first takes place indirectly via the pressure bushing in this position through the inner side of the shaft of the push handle which is usually arranged adjacent thereto. This pressure bushing is actuated by an axial spring force and thus exerts the accumulated force required for the action of the push button on a closed cylinder supported at the inner shoulder on the circumference of the cylinder housing. The freewheeling device of overload is arranged by a lift out form of the shaft which is arranged between the cylinder guide and the pressure bushing. When forcibly rotated, the closing cylinder can maintain contact with the inner shoulder of the cylinder housing due to the pressure bushing which cannot be rotated with the closing cylinder and rise in the axial direction. This is ensured by the stated axial induction of the pressure bushing in the cylinder housing.

The inner part of the handle also includes a control pin at its axial center, the pin now co-operating with the cylinder core via the intermediate shaft connection. The control pins are accommodated in the pressure bushing to enable rotation, but are rigid in the axial direction, thus making the axial connection between the latter as it performs axial movements with respect to the cylinder core with its pressure bushings in the lift-out operating state. The connection is released. Thus, the rotational connection of the cylinder core can no longer be carried out on the control pins arranged successively thereto or on the driver using the control pins. At the point of rotation where the lock is locked, the axial actuation of the push handle combination operates in space and has no effect on the lock member since the driver occupies an inactive point of rotation with respect to the lock member. Since this movement cannot affect the inner part of the handle, the driver cannot be forced into the locked point of rotation by applying a force towards the closing cylinder. The axial spring, which provides the pushbutton action of the handle, performs the additional function of transmitting a disconnection force against the overload free-rotating device in the lift-out section.

The maze guidance device between the driver and the cylinder housing prevents the rotational connection of the driver from the non-operational rotation point where the lock member can be operated by the push handle into the operation rotation point. This can only be achieved by operating the cylinder core by means of a key. The cylinder core can be made an effective driver with respect to the lock member only through control pins axially connected with the cylinder core. The driver does nothing with a forced force because it moves axially through a lift-out feature that results in a free rotation and holds the maze guidance device firmly at its non-operational rotation point associated with the lock member.

Further steps and advantages of the invention are indicated in the following claims and the following description and drawings. Embodiments of the invention are shown in a convenient way in the drawings.

practice

1 shows a locking device according to the invention in a baggage component cover 11 in a vehicle that can be fixed at a cover point closed by a lock member, which is not shown very sufficiently. The lock member is actuated by a push handle 20 which can be ejected into two shaft portions 21 and 22 which in another area overlap another one. The push handle 20 is received in the cylinder housing 10 attached to the cover 11. The wound pressure spring 12 is installed in the cylinder housing 10. The pressure spring 12 encloses the inner portion 22 of the push handle 20 and the interior of the cylinder housing 10 through the ring plate 13 on the snap ring 14 engaged in the inner wall of the cylinder housing 10. Is supported by its foundation. The pressure spring 12 exerts an axial spring force, shown by an arrow 15 on the inner part 22 in FIG. 1, so that the outer part 21 of the push handle 20 adjacent the inner part 22 in the axial direction. It operates simultaneously on the outer side 21. Thus, at its push out point shown in FIG. 1, the push handle 20 tends to deflate the cylinder housing 10 as shown in FIG. 8, but the action indicated by the arrow 23. In the direction of the housing 10. When indicated by arrow 23 at the locked rotational point of the structural component part according to FIG. 8, the driver acts on the lock member via drive arm 51. The starting member 53, which is the only lock member, is shown in FIG. 8 and shows the state pushed in from the push handle 20 point.

The outer part 21 of the push handle 20 consists of a closed cylinder 30 which is conventionally separated in two radial directions in the cylinder guide 31 on the circumference and in the cylinder core 32 axially from the center. The cylinder core 32 is connected with the cylinder guide 31 to increase the strength in the axial direction. This is ensured on the one hand by the snap ring 33 in the circumferential groove of the cylinder core 32 supported at the front of the inner end of the cylinder guide 31. At the opposite end of the closing cylinder 30 a collar 34 is supported through a sealing ring 35 in the inner layer 35 of the cylinder guide 31.

The cylinder core 32 is rotatably supported in the cylinder guide 31 and is opened and locked in rotational position, which results in rotational adjustment 67 of the drive arm 51 (shown in FIG. 1) of the driver 50 (shown in FIG. 1). It can be connected by a key 17 between the points. In FIGS. 1 and 3, the long rotation point 51 is indicated by a solid line, while the open rotation point 51 'is shown by a dotted line in FIG. When the key 17 is pulled out, the cylinder core 32 is drawn only in dashed lines in FIG. 1 and provided in the cylinder guide 31 via a spring loaded strength tool 56 at the point indicated. Meshes with (37), thereby locking together with the cylinder guide (31). However, if the key 17 is fully inserted into the key channel 38 indicated by the line drawn in FIG. 1, the strength tool 38 is aligned on the circumference of the cylinder core 32, and the aforementioned driver. Rotation adjustment 67 of the drive arm can be performed by the cylinder core.

The cylinder guide 31 has an end flange 39 which is shown most clearly in FIG. The closing cylinder 30 may be supported by this end flange 39 in the internal fixture 19 of the cylinder housing 10 via a ring seal 18 as shown in FIG. . The internal fixture 19 serves as a support for the closed cylinder end flange 39 actuated by the axial spring force 15, thereby determining the push out point outwardly shown in FIG. Thus, the outer portion 21 of the handle 20 protrudes the housing casing 24 which is installed on the outer surface of the cover 11 into the inside of the handle which can be pressed in accordance with the arrow 23 shown in FIG. Let's do it. The outer projection of the closing cylinder 30 is covered by a protective sleeve 25 which arises from the end flange 39 and extends to the front end face of the cylinder core 32. The two rotation points of the cylinder core 32 in the cylinder guide 31 can be determined by the catch member whose case consists of a catch ball 26 and a catch groove 27 which are spring loaded inside the cylinder guide 31. Can be.

Similar to the outer portion 21, the inner portion 22 of the push handle 20 is also separated in two radially within the axial center control pin 42 and the pressure bushing 41, ie on the circumference. The inner end of the control pin 42 is stratified, connected with the driver 50 to secure it from rotation, and axially tightly connected with the non-circular carrier via a snap ring, which is very clearly shown in FIG. Two interdependent shaft coupling 40 members 44, 45 of the structure shown very clearly in FIG. 5 are arranged between the outer end face of the control pin 42 and the inner end face of the cylinder core 32. do. These members consist of a front diameter coupling cam 45 in the cylinder core 32 and a front diameter coupling vessel 44 in the control pin 42. Because of the axial spring force 15 acting on the inner portion 22, the axial coupling 40 is normally engaged regardless of the push out point of FIG. 1 or the pushed in point of FIG. As such, the rotational action of the cylinder core 32 affected by the key is transmitted to the driver 50 via the shaft coupling 40 and locked and open rotation points, as mentioned above and shown in FIG. 3. The drive arm 51 of the driver 50 is transmitted between them. The drive arm strikes one actuating arm (indicated by reference numeral 54 in FIG. 8) of the starting member 53 during the crimping operation 23 and by means of its opposite adjustment arm 55. The rotational motion 56 shown in FIG. 8 is only at locked rotation point 51 ′ in accordance with FIG. 3. Thus, the lock member is transmitted within the protruding point of the baggage compartment cover 11.

Thus, the control pin 42 is rotatably supported in the pressure bushing 41, but the inner end of the cylinder core 32 is also engaged inside the pressure bushing 41 so that it can rotate freely. However, it is connected with the pressure bushing 41 to fix the control pin 42 so as not to axially move at the same time. This is stabilized by the circumferential groove 43 in the control pin 42 and the radially inner cam 46 in the pressure bushing 41. The pressure bushing 41 is guided in the cylinder housing 10 in order to be axially deployable but is fixed in relation to the rotary connection therefrom. This is stabilized by the axial induction channel 48 inside the cylinder housing 10 which engages the radially outer cam 47 provided in the circumference of the pressure bushing 41. The outer end of the pressure spring 12 engages in a circumferential annular groove 49 which is installed in the widened end piece 29 of the pressure bushing 41. The pressure spring 12 is supported at the groove base.

The particular lift out shape 60 clearly shown in FIGS. 4 and 6 is arranged between the front end of the widened end piece 29 of the pressure bushing and the end flange 39 of the cylinder guide 31. The lift-out shape 60 consists of a projection 61 formed in the axial direction in the cylinder guide 31 and an axial recess 62 having a counter shape in the pressure bushing 41. As will also be apparent from FIG. 4, since the pressure bushing 41 is operated by the axial spring force of the pressure spring 12 shown in FIG. 1, the recess 62 tends to engage the protrusion 61. There is this. In the normal original position, the engagement point according to FIG. 4 is effective. It is also retained in the compaction operation 23 according to FIG. 8 already mentioned many times. Since the pressure bushing 41 is constantly fixed at the point of rotation determined through its induction means 47 and 48 mentioned above, the predetermined point of rotation of the cylinder guide 31 in the cylinder housing 10 is engaged with the lift. It is provided through the out shape 60. However, these conditions change when a forced rotation is exerted on the outer part 21 of the push handle 20 according to FIGS. 5 and 6.

As shown in FIG. 5, the application of the force can be effected via a screwdriver inserted into the tool 56 for strength, for example in the key channel 38 of the cylinder core 32. Due to the rotating plate 36 currently engaged in the protective channel 37 of the cylinder guide 31, in the cylinder housing 10 the cylinder guide 31 emerges out of the recess 62 having a corresponding count shape. The protrusion 61 is also rotated and lifted up automatically. The protrusion 61 has a trapezoidal shape with stop bevels 63 on both sides. It automatically lifts itself out of the recess 62 upon delivery to this point of rotation. For this purpose, the recess 62 naturally has an axial face 64 with a corresponding inclined joint. The closure cylinder 30 is still supported in the internal fixture 19 via its end flange 39 in this case as shown in FIG. The pressure bushing 41 according to FIG. 6 is pushed out in the axial direction by a slight distance 65 against the repelling spring force l5 coinciding with the height of the projection. By continued forced rotation of the closing cylinder 30, the pressure bushing 41 is naturally supported by the front end front 66 at the planar top of the axial protrusion 61. The pair of protrusions-concave portions 61 and 62 are pressurized with the cylinder guide 31 in order to allow them to simply move into each other protrusion 61 after exactly 1/2 turn 28 provided by force. A pair is provided between the bushings 41 first, but is automatically lifted out again through their fixed bevel 63 and diagonal side 64 when the rotation expires. As such, when the closing cylinder 30 is forcibly rotated 28, the pressure bushing 41 generates vibration of the shaft only inside the cylinder housing 10 without causing the rotational arrangement of the driver 50.

When the space bushing 41 slides upside down, the control pins 42, which are connected to the latter, also slide upside down in accordance with FIG. Ongoing shaft lift 65 from the lift out feature 60 has a length that exceeds the depth 59 in which it engages each other between the vessel 44 and the cam 45 of the shaft coupling 40. Thus, the shaft coupling 40 rises in accordance with FIG. 5 and prevents the transmission of the forced rotation 28 at the outer portion 21 of the push handle 20 towards the inner end 22. The unconnected control pin 42 is not affected by the forced rotation 28 and thus may not install a driver 50 connected thereto in order to be fixed in relation to the rotary connection. If the locked turning point 51 of the drive arm of the driver 50 is in the affected state from starting, the push-in operation 23 of the push handle 20 is as shown from FIG. It can have no operating effect on the starting member 53. In this case, the drive arm 51 lies in a radial plane which is offset by the angle 67 described above with respect to the effective actuating arm 54 of the starting member 53 of the lock. As a result, the pushing 23 has no effect.

This situation can only be changed by a suitable key l7. Rotation adjustment of the cylinder core 32 is possible by means of the key 17 inserted in the manner described above, while the cylinder guide 31 enclosing the cylinder core 32 is pressurized through an interlocking lift out shape 60. It is fixed so as to be held in connection with the rotation by the bushing 41. Also through the currently engaged shaft coupling 40, the rotary connection is directed to the control pin 42 towards the drive arm of the driver 50 which is moved into the open rotation point 51, which is shown in dashed lines in FIGS. 3 and 8. Is delivered from). When the push handle 20 is actuated by press-in, the drive arm 51 hits the actuating arm 54 of the starting member 53 of the lock, as already mentioned, and thus actuates on the lock member. do.

The steps are also taken in the present invention which makes it impossible to carry out the rotary connection of the driver 50 except for the original point of the push handle 20 shown in FIG. This is provided by a complex maze guide 70 arranged directly between the cylinder housing 10 and the driver 50. As can be seen from FIGS. 5 and 8, the driver 50 is in the form of a cap. The interior 68 of the cap engages through the inner end piece 69 of the cylinder housing 10. Two shaft grooves 71, 72 are provided in the circumferential portion of the cylinder housing end piece 69. The sliding block 57 installed in the interior 68 of the cap and shown in FIG. 2 engages in the groove 71 or 72 of the selected axis. A web 73 is installed between two shaft grooves 71 and 72. At the original point of the push handle 20 according to FIGS. 1 and 2, the sliding block 57 is provided at the outer ends of the respective shaft grooves 71 and 72 in which the passage 74 is installed in the web 73. Is installed. The passage 74 is the same size as the sliding block 57.

At the locked rotational point of the structural component parts according to FIGS. 1 and 2, the sliding block 57 is installed in the groove 71 of the shaft when the handle 20 is operated, and is not affected on the lock member. Can generate axial motion. This axial movement is also shown in FIG. 2 by the arrows 23 indicated. In order to achieve an effective point of rotation 51 ′ of the drive arm according to FIGS. 3 and 8 it is necessary to actuate the closing cylinder 30 via the key as described above. Thus, the sliding block 57 is rotated in the guide 70 portion corresponding to the rotation adjustment 67 shown in FIG. 3, similar to the shape of the advanced plane shown in FIG. 2 and FIG. Passes through passage 74 towards point 57 ′ shown in dotted line within 72. When the push handle 20 is actuated by squeezing according to FIG. 8, the sliding block 57 'is arranged in the parallel axis groove 72 in the direction of motion indicated by the arrow 23 in FIG. In this regard, the driving arm 51 ′ of the driver 50 strikes the operating arm 54 of the starting member 53 of the lock according to FIG. 8. The rotational motion 56 of the starting member 53 occurs.

The web 73 serves for the separation of the two shaft grooves 71, 72, which is particularly important when the drive arm of the driver is at the locked rotation point 51. When the forced rotation according to FIG. 5 is carried out on the outer side 21 of the push handle 20, the lateral overlapping between the web 73 and the sliding block 57 is shown in FIG. 7 as shown in FIG. 7. To be seen in the direction of rotation due to the axial lift 65 mentioned in connection with the diagram. The web 57 is then prevented from being connected in the direction of the indicated locking point 57 'by rotating the arrow 67. As shown in FIG. Typically, this is only provided when the compacting action in the movement of the push handle 20 is carried out within the locked rotation point of the sliding block 57. In this case, the sliding block 57 carries out a longitudinal arrangement in its axial groove 71, while the integrated drive arm 51 is in an idle state with respect to the starting member 53 of the lock, It performs its inefficient axial motion in the offset angle plane of FIG.
