Abstract

The invention relates to a key, in particular for a motor vehicle, comprising a housing (30) and a mechanical key part (35) connected thereto. In keys of this type, the locking element of the key part is usually converted from an inoperative position (11) into a working position (15), in which the key (10) can be used to mechanically operate a lock or a locking cylinder, by means of a mechanism (47, 50, 51, 52, 60, 61, 62, 64, 65, 66) which is located in the housing. In order to improve a key of this type, the invention proposes the provision of a traction or force of pressure regulator (50) for the mechanism (47, 50, 51, 52, 60, 61, 62, 64, 65, 66) which acts indirectly upon the actuator (47) via traction or thrust means (51).

Description

Keys, especially for motor vehicles

The invention relates to a key of the type mentioned in claim 1. Keys of this type are used in particular in motor vehicles

From US 2,690,666, as the following state of the art, a key holder is known, in which keys located in a housing can be moved out of the housing via compression springs assigned to them. With this key holder, one key can be selected via a selector switch and the key then released by actuation of a trigger. The selected key is then transferred from the housing into its working position by the force of the compression spring. The springs on the object of the US document engage directly at the rear end of the key, so that they are in the rest position of the key occupy a significant part of the overall length of the key housing in the interior of the housing. However, an increased overall length is not desirable, particularly for key vehicles that remain in the ignition lock while a vehicle is in operation, as the in key protruding into the movement space of a knee, the risk of injury in the area of the right knee of a driver is increased

From US 2,550,375 a key laterally displaceably arranged in a housing is also known. Also with this key, a spring member is arranged in the rear space of the key, which acts directly on the key. However, the spring member is designed here as a tension spring, which pushes the key out of it The position automatically returns to its retracted position when a release button is released that releases the key

A key housing is known from DE-GM 17 13 197, in which a key lying then can be pushed out of the housing or into the housing by manual actuation. The operation of the key via facial expressions acting on it is not apparent from this document The key located in the housing can only be fixed in its retracted position in the housing or pushed out of the housing by means of one or more spring elements

In the case of an electronic mechanical key manufactured by the Huf company, it is known to arrange a foldable and retractable mechanical key on a key housing. With this key, the key electronics are arranged in a first housing part and the mechanical key is arranged in and on a second housing part. The interfaces between the first and the second housing part are very angled and dimensionally complicated with this key

The mechanical key is in the folded state on one long side of the key housing, within a recess that serves as a key holder The key is openly accessible in the receptacle of the housing on its side in the fold-out direction

On the outside of the key there is a release button, by means of which the key can be folded out of its rest position on the housing into a working position, in which the mechanical key can be used, for example, to operate a lock cylinder or an ignition lock.The fold-out process takes place after the release button has been pressed automatically via a spring drive arranged in the key housing, which acts on the mechanical key

To fold in the mechanical key part, the release button must be pressed again and the key must then be manually folded back into its rest position in the receptacle on the side of the housing

The disadvantage of such a key is that dirt particles collect on the key that is openly accessible in the receptacle, which, via the mechanical key, get into the lock cylinder and / or the ignition lock, etc., soiling them over the long term and possibly making them inoperable The opening into which the key can fold is also visually unattractive

A motor vehicle key is known from DE 296 18 616 U1, which can also be transferred by means of facial expressions from a position folded down on one side of the housing to a working position protruding out of the housing

The object of the present invention is to provide a key which has a relatively short installation space and which has a good visual appearance This is achieved according to the invention by the measures mentioned in claim 1, which have the following special meaning. To solve the patented problem, it is proposed to arrange the key part in its rest position inside the housing, the keying after actuation of the release button via a facial expression arranged in the housing its rest position in the interior of the housing is transferred to its working position by a longitudinal displacement, in which at least the closing part of the mechanical key part lies outside the housing.For this purpose, the facial expressions have a tensile or compressive force accumulator which is connected indirectly to the actuator via a traction or thrust means of the key part attacks Through these measures, it is no longer necessary to arrange the traction or pressure force storage in the immediate vicinity of the mechanical key to transfer the moment of motion from the supply or pressure force storage to the mechanical key agen Rather, it is possible to arrange the traction or pressure force storage at any position in the key housing.This way, the traction or pressure force storage can also be arranged laterally next to the key inserted in the housing.The installation space, in particular the installation space length of the key housing, can be reduced as a result a larger range of variations in the design of the key housing is made possible. The tensile force accumulator could, for example, be a tension-loaded spring, a rubber element, a vacuum chamber, a solenoid, etc. The compressive force accumulator can be linear pressure springs, spiral springs, elastic elements (e.g. from Plastic), pressure body, solenoids etc

In the indirect transmission of the adjustment movement from the pressure energy store to the mechanical key, the pushing means can be, for example, a drive belt, an adjusting chain, an adjusting band, a toothed belt, a toothed wheel, etc. In order to ensure a smooth removal of the mechanical key part, means are arranged in the interior of the housing through which the key is guided from its rest position into its working position during the longitudinal movement

Another advantage that results from the solution according to the invention according to claim 1 is that smooth surfaces now predominate at the key housing and there are no more protruding edges and unsightly depressions, so that the key has a very attractive appearance

In addition, the ease of use has been improved by the automatic extension of the mechanical key part and the easy to reinsert it

It can also be advantageous if the key opening in the housing part is designed to be essentially form-fitting to the outer contour of the mechanical key part, so that there is as little opening space as possible between the housing wall and key part, on which dirt particles can penetrate into the interior of the housing Execution of the opening allows stripping of dirt particles that may be caught during or after the actuation

In a further advantageous embodiment of the invention, a means for closing the key opening, such as a flap or a slide that is operated manually or automatically, can be provided according to claim 3, which against the housing part in the rest position of the mechanical key part arranged therein Penetrates dirt completely.

It can be advantageous according to claim 4 if the key is located within the housing part in a guide channel, within which the key is located its longitudinal displacement is favorably used to create the guide channel and surrounding housing walls such as the walls lying on the flat sides of the surrounding housing part to form the guide channel

The guide channel can have a lateral opening through which an actuator, such as a gear or a driving pin, can act on the mechanical key and in this way transmits an adjustment movement exercised by the facial expressions to the mechanical key.

It can also be advantageous if locking means are provided which keep the mechanical keying essentially rigid in its rest and in its working position. After actuation of the release button or another release means, the latching means release the mechanical locking part, so that it can be moved from one position to the other position. The latching means can comprise, for example, hooks arranged on one or more levers, which in the latching position move into a position on the Engage the circumference of the locking part recess, or which engage in a projection, a nose, a counter-locking member, etc. of an actuating means belonging to the facial expressions and thus indirectly hold the mechanical locking part in its working or rest position

When using a traction energy store, it can be advantageous if the traction path of the traction energy store and / or of the traction means actuated by the traction energy store is increased by one or multiple deflection of the traction energy store and / or the traction means on one or more deflection parts, such as, for example, deflection rollers or deflection bars As a result of this measure, the mechanical closing part is largely extended when it is transferred from its rest position to its working position It can also be advantageous to arrange the key electronics and the key mechanism in two self-contained housing parts, both of which are detachably attached to one another along flat connecting surfaces. The battery cover is advantageously arranged on the housing part in such a way that it has the key electronics in such a way that it is covered by the mechanism part in the opposite housing part. To change the battery, all that needs to be done is to separate the two housing parts from each other so that the battery cover can then be opened. A wide variety of connecting means are conceivable for connecting the two housing parts. For example,

Dovetail grooves or depressions and dovetail projections or elevations can be arranged on the housing parts, which, pushed into one another, ensure the connection of the two housing parts.

Further advantages and measures of the invention result from the subclaims, the following description and the drawings. In the drawings, the invention is shown in three exemplary embodiments. Show it:

1 to 8 show a first embodiment of the key 10 according to the invention. In this embodiment, the key is composed of a first housing part 20 and a second housing part 30. The first housing part comprises a housing base plate 22 and a housing cover 21. The housing cover 21 contains touch fields 26 is arranged, by means of which an electronics 25 located inside the first housing part 20 can be actuated. A battery compartment cover 23 is arranged in the housing base plate 22, via which a battery 24, which serves to supply power to the electronics 25, is inserted into and executed in the housing part 20 The first housing part 20 is sealed watertight, the housing cover 21 being fixed to the base plate 22 by means of screw means 29. In this exemplary embodiment, an eyelet 19 is also provided on the key 10, to which, for example, a key tag can be attached

A second housing part 30 is arranged on the first housing part 20 along a planar plane 14. In this exemplary embodiment, the second housing part 30 likewise consists of a housing base plate 32 and a housing cover 31 covering it. Both housing parts 20 and 30 are detachably connected to one another via connecting means 28, 33. In this exemplary embodiment, these connecting means are latching means projections 28 which are in grooves 27 are arranged in the housing base plate 32 of the first housing part 20 and on the side of the second housing part 30 around dovetail pins 33, which are molded onto the housing base plate 32 In order to detach the two housing parts 20, 30 from each other, e.g. for the purpose of replacing the battery 23, both housing parts are displaced relative to one another in the dismantling direction 17 (FIG. 7), it being possible to overcome an initial resistance. The dovetail pins 33 are located after this displacement Arrow 17 in the open part of the groove 27, so that both housing parts 20, 30 can now be separated from one another. For assembly, the two housing parts 20 and 30 must be put together in a corresponding manner, the dovetail pins 33 being inserted into the groove 27 on the opposite housing part must be, and then the housing part 20 are moved in the mounting direction 18 (Fig. 7) relative to the housing part 30. The dovetail pins 33 hook behind the locking means projection 28 in the housing base plate 22 of the first housing part, whereby the two housing parts 20, 30 are fixed to each other by the Setting the both n Housing parts along one level simplify the pre-assembly / disassembly

A key mechanism is arranged in the second housing part 30, via which a mechanical key 35, which is in a rest position 11 in the housing interior 36 of the second housing part 30, is automatically moved into a working position 15 by actuating a release means, such as a release button 70 in which the mechanical key 35 can be used to actuate a locking cylinder or an ignition lock etc. The mechanical key 35 is arranged in the present exemplary embodiment according to FIGS. 1 to 8 as follows in the second housing part 30

A guide channel 37 is arranged in the interior 36 of the second housing part 30, the two flat walls 40 and 41 of which are formed from the flat sides 38 and 39 of the adjacent base plate 32 and the cover 31. The guide channel 37 continues to be on both sides by the walls 42 and 43 The mechanical key 35 is limited in the guide channel 37 slidably arranged. This guide channel 37 is provided at its front end with a key opening 12 through which the mechanical key 35 can get out of the housing part 20 in its working position 15. In its rear area, the guide channel 37 is closed off in this exemplary embodiment by a guide wall 53. The wall 42 facing the narrow side of the mechanical key part 35 has a recess 75 in the rear area of the mechanical key part 35. In the recess 75 1 1 the latching hook 72 of a lever 71 engages, by means of which the mechanical key 35 is held in the rest position 11 The latching hook 72 is held in the recess 75 with the force of a pressure medium 77, such as a spring, which acts on the attachment point 79 on the lever 71 and is supported at the other end in a spring seat 78 on the wall of the housing cover 3 1 Lever 71 is pivotally mounted on an axis 81. The lever 71 is to actuate via a release button 70, which is molded onto the lever 71 in this exemplary embodiment, as a result of which the latching hook 72 disengages from the recess 75 when the mechanical key 35 is seated in its rest position 11

So that the locking hook 72 can reach through the wall 42 to engage in the recess 75 in the mechanical key 35, an opening 45 is provided in the wall 42.

In the front area of the key 10 directly behind a front part 34 of the housing base plate in which the key opening 12 is seated is a second lever

73 arranged, which is pivotable about an axis 83, and a locking hook

74 which engages in the working position 15 of the mechanical key part 35 in the recess 75 in the mechanical key part 35. In the wall 42 of the guide channel 37, an opening 46 is again provided which allows the wall 42 to be gripped by the latching hook 74. The latching hook 74 is in turn by means of the force of a spring 79 '", which at the attachment points 77'" and 78 '"" between the lever 73 and the wall 42 of the housing part 3 1 is fixed Lever 73 is in mechanical contact with the lever 71 at the contact point 84. When the trigger button 70 is actuated, in addition to the lever 71, the lever 73 is also actuated and the latching hook 74 is pulled out of the guide channel 37 and optionally out of the recess 75, when the mechanical key part 35 is in its working position 15. The double lever formed from the levers 71 and 73 enables only a recess 75 at the end of the shaft of the key part to be required on the mechanical key part.

The mechanical key part 35 can be automatically transferred from its rest position 11 into the working position 15 via facial expressions after actuation of the release button 70. For this purpose, in the present exemplary embodiment, a tensile force accumulator 50 is initially provided in the form of a tension spring, which is arranged in the rear area of the housing part 30. The spring 50 is connected to a traction means 51, such as a plastic strand or plastic band, the spring 50 and traction means 51 being guided along the guide wall 53 in the rear region of the housing part 30. The traction means 51 is in turn fixed on an actuator 47, which in turn is firmly connected to the mechanical key part 35, which is arranged in the rear region of the key part 35. The traction means 51 is guided around a deflection roller 52 in the front area of the housing part 30, so that the traction path of the spring 50 and the traction means 51 runs parallel to the extension direction 16 and to the course of the guide channel 37 of the mechanical key part 35. An elongated opening 44 is provided in the side wall 43 of the guide channel 37, through which the actuator 47 extends. The traction means 51 is connected to the nose 48 on the side of the actuator 47 facing away from the guide channel 37.

In the rest position 1 1 of the mechanical key part 35, the nose 48 of the actuator 47 is located on the stop 54 which delimits the longitudinal opening 44 in the rear region. The key is completely retracted into the housing part 30 in the rest position 1 1. To transfer the mechanical key part 35 in In its working position 15, the release button 70 and thus the lever 71 must now be actuated, so that the latch hook 72 moves out of the recess 75 in the mechanical key part 35. The mechanical key part 35 now moves in the extension direction 16 out of the housing part 30 in the direction of extension 16 under the action of the tensile force accumulator his working position 15 When the working position 15 is reached, the nose 48 of the actuator 47 moves against the stop 49, which delimits the opening 44 at its end facing the key opening. As soon as the mechanical key 35 is in this position, the latching hook 74 also snaps into the recess 75 on the mechanical key 35 under the force of the spring

To ruckub the mechanical key holder 35 it learned from its working position 15 to the rest position 1 1, the release button 70 must again be operated manually, whereby the lever 73 is pivoted and the latching hook 74 arranged thereon can move out of the recess 75 in the mechanical key holder 35 the mechanical key holder 35 is manually pushed back into the guide channel 37 in the housing part 30. Shortly before reaching the rest position 11, the mechanical key holder 35 travels with its rear end in the area of its run-up slope 85 against the locking hook 72 and pushes it out against the force of the spring 77 out of the guide channel 37. When the rest position 11 is reached, the latching hook 72 snaps back into the recess 75 by the mechanical key lock and locks the mechanical key lock 35 there

Due to the manual return of the mechanical key part 35 to the rest position 1 1, the traction memory 50 has been pretensioned again so that when the release button 70 is actuated again, the mechanical key 35 can in turn be transferred from its rest position 1 1 to its working position 15 FIGS. 9 and 10 now show a further exemplary embodiment of the closing ice according to the invention. A mechanical key 35 'is in turn arranged in a housing part 30' in a guide channel 37 'located in the housing part 30'. The guide channel 37 'is formed from the two flat walls 40 'and 41', which correspond to sections of the flat sides 38 'and 39' of the housing base plate 32 'and the housing cover 3 1'. The sides of the guide channel 37 'are formed by walls 42' and 43 '. An opening 44 is in the wall 43''through which an actuator 47' formed as a gearwheel extends and the teeth 62 of the gearwheel 47 'engage in a toothing 64 on the mechanical key 35'. The gearwheel 47 'sits on an axis 63 which in this exemplary embodiment is on the housing base plate 32' The gear 47 'has a cavity in its upper region, in which a pressure force accumulator 60, such as a spiral spring, is attached is arranged in the lower circumferential area of the gear below the toothing 62, a recess 76 is provided, into which the latching hook 72 'of a lever 71' protrudes when the mechanical key 35 'is in its rest position or its working position. As in the previous exemplary embodiment, the Lever 71 'to be actuated via a release button 70'. The latching hook is again under the force of the spring 77 ', which is arranged between the frame-side spring seat 78' and the attachment point 79 'on the lever 70'. The mechanical key 35 'is shown in FIG its working position 15 shown in dash-dotted lines is also the rest position of the mechanical key part 35 '

At the housing part end of the mechanical key part 35 ', a nose 48' is formed in the direction of the wall 42 'on the mechanical key 35'. This nose 48 'is in an opening 46' which is in the wall 42 'parallel to the guide channel 37' and the extension direction 16 of the mechanical key part 35 'is arranged. The projection 48' is the extension movement of the mechanical key part 35 ', which is transmitted by the pressure force storage 60 by means of the gear 47' to the mechanical key 35 'when the The release button 70 'has been printed, limited, since the nose 48' moves against the stop 49 'when it reaches the working position 15

To retract the mechanical key part 35 ', the release button 70' must again be actuated, so that the latching hook 72 'moves out of the recess 76 and thus enables the gearwheel 47' to rotate. The mechanical key 35 'can now be inserted into the guide channel 37' again. of the housing part 30 'are inserted, with the gear 47' being rotated and the pressure force accumulator 60 or the spiral spring being pulled up again in order to permit renewed extension. The insertion process is ended when the nose 48 'runs in front of the stop 54' ' opening 46 'delimits at its rear end. In the rest position 1 1 that has now been reached, the locking hook 72 'snaps back into the recess 76 at the lower edge of the gear 47'. The mechanical key 35 'is now locked in the rest position 1 1. The locking of the locking hook 72' in the recess 76 at the bottom The edge of the gear 47 'thus takes place when the mechanical key part is pushed in and out. This means that one revolution of the gear 47' must be equal to the stroke of the mechanical key part

A renewed extension into the working position 15 can in turn take place by actuating the release button 70 ', as a result of which the latching hook 72' again exits the recess 76 and the gearwheel 47 ', which is now released with the force of the spiral spring 60, removes the mechanical key 35' out of the guide channel 37 'and transferred into the working position 15

11 and 12 show a third exemplary embodiment of the closing ice according to the invention. The mechanical key 35 "is arranged in a housing part 30" in a guide channel 37 ". The flat walls 40" of the guide channel 37 "are in turn formed from the flat sides 38" of the housing base plate 32 "and the one not shown Flat side of the housing cover, also not shown, on the narrow sides of the guide channel are walls 42 "and 43", each of which has a channel 67 and a channel 68 in this exemplary embodiment. The wall 43 "has an elongated opening 44" which is parallel to the extension direction 16 of the mechanical key part 35 "runs in the rear area of the housing part 30", a pressure force accumulator 60 "is arranged like a spiral spring, which acts on a gear 65 which is rotatably mounted on an axis 63". The toothing 62 "on the gear 65 engages in tooth openings 66 a thrust means 61, such as a toothed belt, which is guided in the channels 67 and 68, as well as around the gear wheel 65 and on the wall section 53 "located there opposite. At the front end of this thrust means / toothed belt 61 an actuator 47" is arranged by means of of which an adjusting movement exerted by the toothed belt 61 can be transmitted to the mechanical key 35 " At the front end of the toothed belt 61 there is also a locking means 76 'which, in the rest position 11 of the mechanical key part 35 ", rests on the latching hook 72" of a lever 71 "under the actuating force of the pressure force accumulator 60". The locking means 76' lies above that Wall section 53 "of wall 47"

The lever 71 "is pivotally mounted on an axis 81". It has a release button 70 "at its second end, by means of which the latching hook 72" against the spring force of a spring 77 ", which is located at the attachment points 79" and 78 "between the front Arm of the lever 71 "and the house-side wall 43" is arranged

The key according to the invention is shown in FIG. 1 1 in the rest position 11 of the mechanical key part 35 ". The mechanical key part 35" lies entirely in the guide channel 37 "behind the key position 12 on the house side If the release button 70 "is actuated and the lever 71" is pivoted counter to the force of the spring 77 ", the latching hook 72" releases the locking means / locking element 76 '. As a result, the pushing means 61 with the actuator 47 "thereon can now be moved due to the the moment of motion exerted by the pressure force accumulator 60 ", which is transmitted from the pressure force accumulator 60" to the gear wheel 65 and from there via the toothing 62 "and the tooth opening 66 to the pushing means 61, is moved in the extension direction 16 to the key opening 12, as a result of which the actuator 47" actuated mechanical key 35 "is moved out of the housing part 30" into its working position 15. When the working position 15 is reached, the nose 48 "of the actuator 47" moves in front of a stop 49 "which is arranged at the end of the opening 44". , which is provided with a run-up slope in the extension direction, is driven behind the locking hook 72 "during the extension movement and prevents nu n via the pushing means 61 and the actuator 47 "retracting the mechanical key part 35"

When the release button 70 "is actuated again, the locking means 76" is released again and the mechanical key 35 "can be manually pushed back into the guide channel 37" in the housing part 30 ". As a result, the pushing means 61 moves past the gear 65 in the reverse direction, which is thereby moved again so that the spiral spring 60 "articulated on the gear 65 and located in the gear 65 is tensioned again with the insertion movement of the mechanical key part 35". Shortly before the rest position 11 is reached by the mechanical key 35 ", the locking means moves / Locking member 76 'with its run-up slope against the locking hook 72 "and pushes past it. The locking hook 72" moves under the force of the spring 77 "behind the locking means / locking member 76' and blocks a retraction of the mechanical key part 35" under the Force action of the pressure energy accumulator / coil spring 60 "To insert the mec Han key part 35 "to avoid is at the rear end of the opening 44 "a stop 54" is provided, against which the nose 48 "of the actuator 47" moves when the mechanical key part 35 "is inserted. At the same time, the locking means 76" runs against a stop 56 which lies at the end of the wall 42 "

In addition to the exemplary embodiments shown here, other embodiments are also conceivable. In particular, embodiments are conceivable in which the key opening can be closed by another means if the mechanical keying is completely in the guide channel

Furthermore, an embodiment is conceivable, for example, in which a linearly acting and linearly adjustable compression spring acts directly on an actuator, such as the actuator 47 or 47 ", and such a mechanical key can be pushed out of a housing part. Such a linearly acting compression spring can For example, be arranged in a further guide channel adjacent to the guide channel for the mechanical keying, or else have such a stiffness that a guide of the spring element is not necessary

Mechanical key tapping could also be pushed out of the housing section using electrically controlled solenoids or hydraulic pressure accumulators. Likewise, instead of a latching, frictional braking means can also be provided which hold the mechanical keying in its respective positions

It also goes without saying that the connecting means between the electrical housing part and the mechanical housing part can also be arranged differently than in the first exemplary embodiment. Thus, the grooves 27 and the locking means projections 28 could also be in the housing base plates 32, 32 ', 32 "of the key mechanism containing the key mechanism the second housing parts, the dovetail pins 23 would then have to be arranged in the housing base plates 22 of the first housing parts containing the electronics.
