Description

The invention relates to a device for Actuation of actuators, especially ventilation flaps, heating flaps or the like, esp especially in motor vehicles, consisting of a movable on a fixed housing part mounted control lever in the form of a slide, a turning handle or the like and one Means for transmitting longitudinal movements in a flexible guide sleeve, for example one Bowden cable, with the guide sleeve attached to the standing housing part and the means for over wear of longitudinal movements attached to the lever is, wherein also the free end of the guide sleeve on another immovable housing part, for Example on the heater housing, is attached and the free end of the means for transferring the Longitudinal movements on the movable, in particular pivotable actuator is held.  

In such devices, it is common that Ventilation flaps, heating flaps or the like Actuators operated by means of a Bowden cable be, the handle for actuation on Dashboard or near the seat is arranged and the handle in the form of a rotary handle or can be designed in the form of a slide, whereby in each case by actuating the handle or of the slide a longitudinal movement of the means for transmitting longitudinal movements in its bend is achieved through which Longitudinal movement of the end with the transmission medium coupled control lever or the like be can be done. The preparation of such pre directions takes place in such a way that the Handle including the associated housing parts with the Bowden cable is equipped and this handle together Bowden cable later installed in a motor vehicle becomes.  

The assembler must on the one hand the end of the Guide sleeve on the housing of the heater or the Attach ventilation or the like and on the other hand the end of the transfer means to match that set the control lever or the like. These Work is very difficult to do because of the space available for handling is very narrow at the installation location in the motor vehicle, so that the usual arrangement by means of Screws or the like is extremely time consuming and is therefore expensive.

Based on this state of the art Invention the task based on a genus to create appropriate device that is easy to use is in place and with little effort in force vehicle is to be assembled.

To achieve this object, the invention proposes that  the fastener for the free end of the Guide sleeve in a corresponding housing wall recess is a snap-in spring clip, which is firmly connected to the envelope that the loading fixing agent for the free end of the agent to transmit the longitudinal movements at the end of the the latter a further one in a corresponding one Recess of the actuator spring that can be broken in is clamp and that both spring clips by one Coupling member are connected, which is the spring clamp in one of the recesses of the housing and Actuator corresponding distance from each other holds.

On the one hand, the invention makes it simple Production enables, since the not according to the invention agile spring clips as well as the coupling technically simple in structure and therefore one are to be produced professionally. It is also the assembly  considerably simplified, since now as before the actuator on the mounting part except half of the motor vehicle can be attached and thereby for coupling with that in the motor vehicle provided spring to be operated organ clamp at the factory with the coupling link are connectable. To install the device there is now only one hand in the motor vehicle handle to perform, namely, the coupling member together with spring clips in the corresponding installation brought into position and the spring clips in the ent speaking installation openings. During this process, the spring clips are still with each other via the coupling link connected. After installation in the intended The coupling member is then to be removed distant or at least separate so far that the  Function of the device is guaranteed. The Coupling member can, for example, from a rope like element, but then due to the flexible connection of the two springs clamp handling during assembly still in ge to some extent can be complex. It is better, if the coupling member is a rigid part forms, so that the spring clamp spacing is rigid is defined and thus a single hand handle the correct position is possible.

It is preferably provided that the means for Transmission of longitudinal movements is a steel wire. This arrangement is itself from the prior art known.

It is further preferred that the coupling member is releasably attached to the spring clips.  

In this way, the coupling member, if this is desired to be used multiple times by namely from the place of final assembly back to the place of Pre-assembly is transferred and re-determined according to is used.

Alternatively, it is also possible for the coupling member has a severable paddock.

The paddock is then a lost component, which after fulfilling its intended function is separated and removed.

It is also advantageous that the spring clips out Plastic.

It is particularly preferred that the shell-proof spring clamp from a cuboid, the envelope around closing body, whose axial Er stretching of the cover in front, exposed end face  from the means for transmitting longitudinal movements through gripped is that the spring attached to the latter clamp has a U-shaped profiled body, whose leg parallel to the longitudinal extension of the Transfer means directed and between those at the base of the body the transmission middle end is supported that both spring clips Have strut pairs that are transverse to the longitudinal Strive for the stretching of the casing and transmission medium and that the coupling member is rigid and is releasably supported on the spring clips, wherein it outside the insertion path of the shock absorber pairs is arranged.

With this training, the case can be connecting bodies directly to the shell be sprayed while the spring clip on Means for transmitting longitudinal movements after can be attached to this sluggishly. By  the designated arrangement is the function of the front direction ensured and yet the invention appropriate installation aid very simple and advantageous realized.

It is further preferred that transverse to the axial Er extension of the spring clamp body as axial Limit stops trained, at least about spring clamp body-high web pairs are arranged, the Slits for reaching through the casing or the longitudinal have motion-transmitting means.

Consider tolerances with regard to the installation dimensions tigen, it is advantageous that the web pairs for a spring clamp body a slightly larger one have a clear distance from each other than the length of the associated spring clamp body.

A the manufacture of the support plate including the Spring snap pairs facilitating training  seen in that the support plate between the associated spring latch pairs is perforated, wherein the spring catches facing each other engage within the projection of the perforation are arranged.

A very simple and functional next Education is seen in the fact that the spring clamp body on their flat surfaces facing the spring catches graspable by the locking lugs of the spring catches have molded, projecting retaining webs.

It is further preferred that the strut pairs of Spring clips close to those in axial extension see front and rear ends of the clamps are molded and rest on the outer surfaces have noses.

To the spring clips easily in the event of a defect To be able to remove from the built-in housing struck that the strut pairs in their longitudinal extending a beyond the locking lugs Have extension.  

The extensions are from the inside of the housing using a tool or manually accessible so that by compressing the spring pairs of legs on the extensions the Rastver bond released and the corresponding defects Parts are interchangeable.

It is particularly preferred that the ends of the Extensions of the spring strut pairs of a spring clamp body diverging towards the free end are trained.

A further advantageous the assembly and function influencing further training is seen in that the spring clip for fastening the agent to transmit the longitudinal movements between them Thighs a recording for that in particular as Round wire trained means, as well as the free leg ends diverging guide has surfaces, with the one on the right  Angled angled round wire in the nominal clamp lay in a suitable hole in the base of the Auf intervenes, which hole and also that Wire end also the base of the spring clip itself reaches through.

Is technically advantageous if the Spring clips and support plate in one piece are molded from plastic.

It is advantageous if the axial distance of the Spring latch pairs on the support plate during installation distance between the two spring clips.

In certain applications, it has proven to be disadvantageously highlighted when the spring clamps side end of the means for transferring the longitudinal movements on the spring clip are fixed is. For the purpose of adjusting the stops of the Lever or the rotary handle, it would be advantageous stick if the holder of the means for over do not carry the longitudinal movements on the spring clip would be rigid but movable.  

For this reason, the invention proposes that on the spring clip for fastening the agent a clamp to transmit the longitudinal movements is spring-mounted, the at least two spring legs between which this is particularly round wire trained means can be clamped, the Clamping force is greater than that when the by the actuatable actuator occurring tensile or compressive force.

The fact that now the means of transferring the Longitudinal movements, especially the round wire, do not is held more rigidly at the spring clip, but only clamp with an additional clamping spring connected, is the normal on the one hand Operation of the device possible without the relative position of the round wire relative to Spring clamp changes. If, however, in particular with the Initial assembly of the rotary handle or the adjusting lever are not in the starting position, the travel range of the component connected to the spring clip is already at its end stop, so under  increased effort the handle to zero position are transferred, with the round wire pulled through the clamping spring with effort until the zero position is reached. Below is the normal adjustment of the Device possible.

The adjustment option described above is beneficial is the measure that the clamping spring is U-shaped Spring steel is bent, the side longitudinal edge edges to form the clamping spring legs are bent over each other.

Furthermore, it is beneficial that one the spring leg of a pair of springs has a recess in its correspondence area, in which the Round wire is partially insertable.

It is also advantageous that the clamping spring on the facing away from the spring legs of the spring clip Side of the same is arranged.  

It may be advantageous that the spring legs of a pair of springs together swear.

It is preferred that the spring legs of a spring pair at least offset by their wall thickness are arranged facing each other.

The invention is based on a Embodiment explained in more detail.

The device according to the invention is based on a Example shown in which the actuator for actuating the heating flaps of motor vehicles serves.

As can be seen from Fig. 1, the device for actuating heating flaps and similar actuators in motor vehicles consists essentially of a housing part 1 which can be built on a dashboard, for example, with at least one displaceably mounted actuating lever 2 in the form of a slide. Furthermore, the device consists of a means 3 for transmitting longitudinal movements in a flexible guide sleeve 4 , in particular a Bowden cable. The means 3 is formed in the execution example as a round wire. This wire is designed at one end as a hook 5 and can be connected to the adjusting lever. The guide sleeve 4 is attached to the housing 1 by means of a suitable device and is held adjustable by means of an adjusting screw 6 . At the free end of the guide sleeve and the wire further elements are arranged, which will be described later. 1 is supplied by the manufacturer to the respective automobile company in the form completed according to FIG. 1, where the connection of the connecting elements arranged at the free end of the Bowden cable with the corresponding organ to be set, for example the heating, then takes place.

As a fastening means for the free end of the guide sleeve 4 , a spring clip 7 is provided in a corresponding housing wall recess, not shown, which is firmly connected to the sleeve 4 . The connection can be made, for example, in such a way that part 7 is molded onto part 4 .

As a fastening means for the free end of the means 3 which transmits the longitudinal movements, a further spring clip 8 which can be blasted into a corresponding recess in the (not shown) actuator is provided at the free end thereof. The attachment of this spring clip 8 to the part 3 will be described later.

Both spring clips 7 , 8 are rigidly connected to one another by a coupling member 9 , which clamps the spring clips 7 , 8 at a distance from one another which corresponds to the recesses from the housing and from the actuator. According to the embodiment, the coupling member 9 is releasably attached to the spring clips 7 , 8 . The spring clips as well as the coupling member are made of plastic.

The sheath-fixed spring clip 7 consists of a cuboid, the sheath enclosing body 10 , the front end face 11 of the means 3 for transmitting longitudinal movements is penetrated in the axial extension of the sheath 4 at the front. The spring clip 8 attached to the latter has a U-shaped body 12 , the legs of which extend parallel to the longitudinal extent of the transmission by means of 3 and between which the transmission means is held at the base of the body 12 , as will be described later. Both spring clips 7 , 8 have pairs of struts 13 and 14 , which strive transversely to the longitudinal extent of the shell 4 and transmission means 3 . The coupling member 9 is rigid and releasably supported on the spring clips 7 , 8 , wherein it is arranged outside the insertion path of the strut pairs 13 , 14 . The coupling member 9 consists of a support plate 15 with spring catches 16 and 17 striving at right angles therefrom in the same direction. Each pair of spring catches 16 and 17 serves as a receptacle for one of the two spring clips 7 , 8 . On the support plate 15 , parallel to the axial extension of the spring clamp body or the sheath 4 and the means 3, the spring catch pairs 16 and 17 are formed opposite one another, the distance between the spring catches of a spring pair 16 and 17 to the transverse dimension of the associated clamp body 7 , 8 is coordinated. Transverse to the axial extent of the spring clamp bodies 7 , 8 are each formed as axial limit stops, at least approximately spring clamp body-high web pairs 18 and 19 , which have slots for penetrating the sheath 4 or the longitudinal movement transmitting means. The pairs of webs for a spring clamp body 7 or 8 each have a slightly larger clear distance from each other than the length of the associated spring clamp body speaks ent, so that it is at least slightly longitudinally displaceable between the webs 19 or between the webs 18 . This game is used to compensate for tolerance and thus facilitates assembly.

The support plate 15 is provided with perforations 20 and 21 between the associated pairs of spring catches 17 and 16 , respectively. The aligned lugs of the spring catches 17 and 16 lie within the projection of the perforations 20 and 21 , as can be seen in particular from FIG. 4d. A tool access for forming the locking lugs is thus achieved through the perforations.

The spring clamp bodies 12 and 11 have on their flat surfaces facing the spring catches 17 and 16 , respectively, from the locking lugs of the spring catches behind, molded, projecting retaining webs 22 .

The strut pairs 13 and 14 of the spring clips 8 and 7 are each formed near the ge in axial extension front and rear ends of the clamp body 11 and 12 are formed on the underside and have the locking lugs on their outer surfaces, as is particularly clear Fig. 2c and Fig. 3c it clearly. Furthermore, the strut pairs 13 and 14 preferably have an extension 23 which extends beyond the latching lugs, the ends of the extensions 23 of the strut pairs of a spring clamp body being designed to diverge towards the free end, as can also be clearly seen in particular from FIGS. 2c and 3c . This measure serves to facilitate the attack of a tool or fingers, provided that such a spring clamp is to be subsequently removed from the corresponding fastening perforation for the purpose of replacement.

The spring clip 8 for fastening the means 3 for transmitting the longitudinal movements has a receptacle 24 between its legs, as can be seen particularly clearly from FIG. 3 b. This receptacle 24 , which in the exemplary embodiment is designed as a receptacle for a round wire (means 3 ), is approximately U-shaped and has an almost circular profiled longitudinal recess 25 with open mouths, with diverging guide surfaces 26 being formed on the free leg ends. The round wire (means 3 ) to be fastened in this receptacle 24 is angled at the end at right angles, as can be seen particularly clearly from FIG. 2c. To fix it in the desired clamping position, the base of the receptacle 24 has a suitable hole 27 , which also extends through the base of the spring clamp body 12 .

The means 3 is thus locked within the receptacle 24 and locked in the longitudinal direction by the angled abge, inserted into the hole 27 end. Describes the preparation and application of the performed before direction in such a manner that the spring clamp 7 is initially at the free end of the sheath 4 is injected and later the spring clip 8 with the angled end of the medium 1 latched for transferring longitudinal motions and locked. The spring clip 8 is thus manufactured beforehand as an independent molded part. After the spring clips 7 and 8 are properly attached to the parts 3 and 4 , the coupling member 9 is locked on the spring clip bodies 7 and 8 , so that the parts 7 , 8 , 9 form a functional unit. This functional unit can now be inserted very easily and with only one hand into the narrow space in which the corresponding receiving openings for the spring clips 7 , 8 are arranged. The spring clamp 7 is inserted into the perforation of a frame-fixed part, while the spring clamp 8 is inserted into a perforation of a pivot lever or the like, so that the pivot lever can be moved into its functional positions by actuating the handle 2 . After proper installation, so if the spring clips 7 and 8 are locked at the associated installation locations, the assembler can move and remove the coupling member 9 from the spring clips 7 , 8 with the same loading movement and the same hand, so that the proper function of the Bowden train is ensured. The coupling member 9 can now be reused or can also be supplied to a preparation process.

An advantageous variant is shown in the drawing figures 5 to 8 . The main difference from the other embodiments is that, according to this embodiment, a clamping spring 28 is held on the spring clamp 8 for fastening the means 3 for transmitting the longitudinal movements. This clamping spring has two pairs of spring legs 29 , 30 , between which the means 3 designed as a round wire can be clamped. The clamping force of the spring leg 29 , 30 is set so that the clamping force is greater than that normally when actuating the means 3 for actuating the actuator to occurring tensile or compressive force. A relative displacement of the means 3 relative to the spring clamp 8 is only possible when the actuating lever for the means 3 is set to zero, by pulling the means 3 with a greater force than the clamping force of the spring legs 29 , 30 by the clamping spring 28 .

The clamping spring 28 is U-shaped and consists of spring steel. It is essentially U-shaped out, its side longitudinal edge edges to form the clamping spring legs 29 , 30 to each other are bent. This can be seen particularly clearly from FIG. 8.

In addition, one of the spring legs of a pair of springs 29 or 30 has a slight recess in its correspondence surface, into which the round wire 3 can be partially inserted.

However, it must not be fully inserted, because then there is no longer sufficient clamping force would be cash.

In the exemplary embodiment, the surface of the spring clip 8 which is exposed externally after assembly has been used for the arrangement of the clamping spring 28 . As can be seen in particular from the illustration in Fig. 8, the spring legs of each pair of springs 29 and 30 are arranged offset from one another at least by their wall thickness, so that a sufficient preload of the spring legs is possible without the spring legs of a pair interfering with one another or would mutually form the end limit stops.

This training is a very simple one and advantageous adjustment possibility of the device given, without there being any special order wall, in particular an assembly effort.

The invention is not based on the embodiment limited, but within the scope of the revelation often variable.

All new, in the description and / or drawing disclosed individual and combination features regarded as essential to the invention.
