Description
Motor vehicle door lock Description:
The invention relates to a motor vehicle door lock with an actuation/locking lever mechanism with a first lever and a second lever with both levers being couplable with each other in at least two different relative positions.
The prior art disclosed in DE 23 55 556 A describes a motor vehicle door lock with a locking mechanism containing a tong case with two tong arms. The two tong arms are mounted respectively on bolts. In addition, a spring is provided that is supported by the two bolts of the tong arms.
The generic state of the art according to DE 89 16 180 U1 discloses two levers, a coupling lever and an actuating lever that can be coupled to each other and in different relative positions. One relative position corresponds to the coupled state, whilst another relative position corresponds to the uncoupled state. In principle, this arrangement has proven to be successful. The known solution requires, however, a kinematically complicated design and is hardly suitable for other applications as the change in coupling position is achieved by a double stroke activation.
In more modern motor vehicle door lock versions equipped with a so-called quick release function, this quick release function ensures that the actual unlocking operation carried out by a motor is shortened, for instance as part of a so-called "keyless entry" function. For this purpose, various actuating operations are required, with the aid of which the actuating lever chain is directly moved into the unlocked state or a previously interrupted mechanical connection to the release lever is produced (see DE 10 2005 043 227 B3). This arrangement has generally been successful can, however be improved as regards the coupling used between the levers integrated in the quick release unit. Indeed there is the general possibility or even danger with this arrangement that two levers coupled during this process are not exactly aligned with each other in their relative position, resulting in malfunctioning. The invention seems to remedy this situation.
The invention is based on the technical problem of developing such a motor vehicle door lock further in such a way that the coupling of the two lever functions and, in particular, the assumed relative positions can be safely and reproducibly attained and maintained.
In order to solve this problem, a generic motor vehicle door lock of the invention is characterized by at least the first lever containing a connected detent spring for cooperation with at least one detent contour on the second lever.
The detent spring can be connected to the first lever. In this context it is possible that the detent spring and the first lever form and define a single component.
Generally, the detent spring can, however, also be connected to the first lever in any possible manner. It is possible, to couple the respective detent spring to the first lever by riveting, bolting, etc.
In all cases, the first lever with the connected detent spring ensures that the second other lever is acted upon by the detent spring.
For this reason, the lever with the detent spring is in most cases designed as a fixed lever. The second lever with the detent contour is, on the other hand, a detent lever arrangable in different detent positions in relation to the fixed lever. This means that the fixed lever regularly maintains its position whilst the detent lever is designed to be moved in relation to the fixed lever and against the force of the detent spring into the different detent positions. In most cases, at least two detent positions can be realised.
According to an advantageous embodiment even three or more detent positions can be defined.

Indeed there is the general possibility or even danger with this arrangement that two levers coupled during this process are not exactly aligned with each other in their relative position, resulting in malfunctioning. The invention seems to remedy this situation.
The invention is based on the technical problem of developing such a motor vehicle door lock further in such a way that the coupling of the two lever functions and, in particular, the assumed relative positions can be safely and reproducibly attained and maintained.
In order to solve this problem, a generic motor vehicle door lock of the invention is characterized by at least the first lever containing a connected detent spring for cooperation with at least one detent contour on the second lever.
The detent spring can be connected to the first lever. In this context it is possible that the detent spring and the first lever form and define a single component.
Generally, the detent spring can, however, also be connected to the first lever in any possible manner. It is possible, to couple the respective detent spring to the first lever by riveting, bolting, etc.
In all cases, the first lever with the connected detent spring ensures that the second other lever is acted upon by the detent spring.
For this reason, the lever with the detent spring is in most cases designed as a fixed lever. The second lever with the detent contour is, on the other hand, a detent lever arrangable in different detent positions in relation to the fixed lever. This means that the fixed lever regularly maintains its position whilst the detent lever is designed to be moved in relation to the fixed lever and against the force of the detent spring into the different detent positions. In most cases, at least two detent positions can be realised.
According to an advantageous embodiment even three or more detent positions can be defined.
In order to achieve this in detail, the detent spring and the detent lever can be arranged on the same plane. In this case, the spring force exerted by the detent spring acts in the direction of the plane of the detent lever acted upon by the detent spring.
It is, however, also possible and feasible that the detent spring and the detent lever are arranged on different planes. In this case, the detent spring and the detent lever thus describe different planes, regularly arranged to each other at an angle.
In most cases it has proven to be advantageous in this context for the detent spring and the detent lever to be arranged perpendicularly to each other. This means that in this situation the detent spring exerts a spring force perpendicular to the plane formed by the detent lever.
A particularly cost effective and well functioning solution is characterized by the detent lever being mounted on the fixing lever in a rotary axis. The detent spring is arranged in the area of the rotary axis. In this situation, the detent spring ensures in case of the detent spring and detent lever being arranged on the same plane that the detent spring acts upon the detent lever with a perpendicular force in relation to the axial direction of the rotary axis. In contrast, the arrangement of the detent spring and detent lever on different planes, in particular their perpendicular arrangement to each other, cause the detent spring to act on the detent lever with an axial force.
In this case the spring force exerted by the detent spring acts in axial direction of the rotary axis. In general, the axial force and the force perpendicular to the axial direction of the rotary axis can also at the same time be applied to the detent lever.
In a preferred embodiment, the detent spring is a leaf spring. In this case the first one lever or fixed lever has an L-shaped cross section with the detent spring being arranged on an L-leg. As a result, the one first lever or fixed lever and the detent spring can be produced at the same time, which is particularly cost effective.
The detent contour can be a detent recess at least partially accommodating the leaf spring. The detent recess then also provides a stop in most cases. This stop represents a first detent position. In addition, at least another second stop can be provided, corresponding to a further detent position of the detent lever in relation to the fixed lever.
As part of an alternative method, the detent spring can also be a spring washer. A coil spring containing several such spring washers can also be provided in this context. In this case, the detent contour is typically designed as a stop edge interacting with the projection on the detent lever. The stop edge is located on the fixed lever, whilst the projection on the detent lever interacts with this stop edge on the fixed lever. The abutting of the projection on the detent lever against the stop edge of the fixed lever corresponds to a first detent position. A further second detent position can be assumed by the detent lever when a further stop edge is being used on the fixed lever.
Where the fixed lever is a longitudinal strip-like lever, the two longitudinal edges of the lever are each available as a stop edge for the first and second detent position.
As part of the invention, the detent lever is designed to assume at least three different detent positions. In this context it has proven to be advantageous if the detent spring and the detent lever are arranged on the same plane. This then allows the option of having the leaf spring or detent spring formed on one L-leg of the fixed lever cooperate with one polygon-like contour at the end of the detent lever.
Depending on the number of edges of this polygon-like contour or polygon structure, any number of detent positions between the detent lever and the fixed lever can be provided in theory. Each detent position corresponds to one edge of the leaf spring abutting against the polygon structure. In principle this polygon structure can also be combined with a spring washer as a detent spring. In this case it is feasible that the spring washer contains axial webs spanning the polygon structure and that each detent position corresponds to the polygon structure being, as it were, turned in relation to the finger-like spanning axial webs.
Where the detent lever assumes two or more detent positions compared to the fixed lever it has proven to be advantageous, if at least one of the detent positions can solely and exclusively be fixed with the detent spring. This means that in this case the detent position is solely defined by the cooperation between the detent spring and the detent contour ¨ without additional stop.
At least one of the several detent positions can, on the other hand, be fixed with the aid of the detent spring as well as with the aid of a stop. In this case it is on one hand the cooperation between the detent spring and the stop contour and, on the other hand, the stop and the detent lever as a whole that ensure that the detent lever assumes the respective detent position. Generally it is, of course also feasible that all detent positions of the detent lever can only be fixed in relation to the fixed lever by means of the detent spring. Also, all detent positions can only be defined due to the fact that the detent spring and the respective associated stop ensure that the detent lever assumes its desired detent position in relation to the fixed lever.
Preferably, the detent lever is an unlocking lever and, in particular, a quick release lever. In this case the detent lever can be part of an unlocking lever chain.
In contrast, the fixed lever is generally part of the actuating lever mechanism. To implement the quick release function, the detent lever is pivoted into a displaced position or second detent position compared to the first detent position or base position. This operation can be motor driven or manual. As a result of the quick release lever or detent lever assuming this displaced position, a release lever acting upon a locking mechanism can, for instance, be directly displaced via the activation lever chain so that the locking mechanism is opened without hardly any delay. The whole operation is quick, works reliably and is reproducible as the base position and displaced position of the detent lever or of the quick release lever is correctly and reproducibly assumed as a result of the cooperation with the detent spring. These are the main advantages.
Below, the invention is explained in detail with reference to a drawing showing only one embodiment, in which:
Fig.1 shows a first version of the motor vehicle door lock of the invention, Fig. 2 shows a section along line A-A of the object of Fig. 1, Fig. 3 shows an enlarged view of a modified embodiment of Fig. 1, Fig.4 shows a longitudinal section of the second version of the motor vehicle door lock of the invention and Fig. 5 shows a top view of the version of Fig. 4.
The figures show a motor vehicle door lock containing an actuating lever mechanism 1 and an unlocking lever mechanism 2. The example only shows a first lever or fixed lever 1 of the actuating lever mechanism 1 whilst the locking lever mechanism 2 is also only represented by a second lever 2. In the actual installed situation ¨
not shown in detail - the actuating lever mechanism 1 and the locking lever mechanism 2 contain also other levers, not identified further, which are of no importance in the present case.
As usual, the actuating lever mechanism 1 is typically mechanically connected to a handle, e.g. an internal door handle and/or external door handle. Activation of the handle for opening a motor vehicle door belonging to the shown motor vehicle door lock results in the first lever or fixed lever 1 being pivoted around a respective rotary axis 3 in counter clockwise direction in the embodiment shown in Fig. 1, as indicated by an arrow. During these pivoting movements, the detent lever 2 mounted on the fixed lever 1 in the rotary axis 3, does not reach the indicated release lever 4.
When, on the other hand, the detent lever 2 assumes its displaced position or second detent position in comparison to its first detent position or base position ¨
shown by a solid line ¨ in comparison to the fixed lever 1 ¨ shown by a dashed line ¨ the already discussed pivoting movement of the fixed lever 1 triggered by the handle, causes the release lever 4 to be acted upon. As a result, the handle is now able to open a locking mechanism ¨ not shown in detail - by means of a release lever 4. The triggering lever 4 does, indeed act on a pawl ¨ not shown ¨ lifting it off the rotary catch.
The rotary catch opens with the aid of the spring and releases a previously retained locking pin.
As a result, the motor vehicle door can be directly opened.
The described process corresponds to a quick release which is achieved manually and/or with the aid of a motor, by the detent lever 2 being moved in the example from its base position ¨ shown by a solid line ¨ to its deflected position ¨ shown by a dashed line. Both levers 1, 2 are indeed coupled to one another in at least two different relative positions, the base position and the deflected position, as described.
This coupling is a detent coupling, as the first lever or fixed lever 1 contains a connected detent spring 5. The detent spring 5 is arranged to cooperate with at least one detent contour 6 at the other second lever or detent lever 2. In the embodiments shown in Fig. 1 to 3, the detent spring 5 is formed on the first lever or fixed lever 1.
The detent spring 5 and the first lever 1 do actually form a single-part component.
From the respective sectional view of Fig. 2 it is also apparent that the fixed lever 1 together with the single-piece detent spring 5 forms an overall L-shaped lever 1, 5 in cross section. The fixed lever 1 defines the longer L-leg, whilst the detent spring 5 is arranged on the shorter Lleg. In this way, the fixed lever 1 and the detent spring 5 can be produced in one and the same operation, keeping costs to a minimum. The detent spring 5 is also designed as a leaf spring 5.
It is apparent that the detent spring 5 and the detent lever 2 are arranged on the same plane in the example shown in Fig. 1 to 3. This means that the spring force F
exerted by the detent spring 5 acts in the direction of the plane defined by detent lever 2. This is indicated in Fig. 1 by a respective force arrow F for the spring force F
exerted by the detent spring 5.
The aforementioned detent contour 6 on the detent lever 2 corresponds to the detent spring or leaf spring 5. In the embodiment shown in Fig. 1 to 3 the detent spring 5 or leaf spring 5 has a rectangular cross section, so that the contour 6 also has a square form. As a result, the detent contour 6 also forms a stop 7 for the front end of the leaf spring 5.
The stop 7 and the cooperation between the detent spring 5 and the detent lever 2 define the first detent position or the base position of the detent lever 2 ¨
shown by a solid line - in Fig. 1 in relation to the fixed lever 1. When the detent lever 2 is pivoted out of this position into the deflected position shown by the dashed line, with the effects already described above, a further stop 8 is provided, which again with the cooperation between the detent spring 5 and the detent contour 6 ensures that the defined displaced position of the detent lever 2 is taken up. The stop 8 ¨
like the detent spring 5 ¨ is formed on the fixed lever 1 (single component).
Manufacture is therefore simple and quick. For actual functioning it suffices to define the fixed lever 1 together with the bevelled detent spring 5 and the bevelled and also connected stop 8 and then to only pivotally connect the detent lever 2 with the help of the rotary axis 3 to the fixed lever 1.
Fig. 3 shows that the detent lever 2 is not only arranged and suited to assume the two detent positions shown in Fig. 1, i.e. the base position and the displaced position. The detent lever 2 can also assume three or more different detent positions. For this purpose the detent lever 2 has, in the version shown in Fig. 3, one polygon contour 9 with several edges 10 in the area of its end on the rotation axis side.
Depending on the number of edges 10 of the polygon contour 9, three, four or even more different detent positions of the detent lever 2 can be defined and arranged in relation to the fixed lever 1. In the example, each detent position corresponds to the detent lever 2 being only fixed with the detent spring 5. In other words, no additional stops are used, although this is of course possible and is part of the invention. In the described versions of Fig. 1 to 3 the detent spring 5 and the detent lever 2 are, as explained, arranged on the same plane. The design is such that the detent spring 5 acts on the detent lever 2 with the force or spring force F extending perpendicularly to the axial direction of the rotary axis 3, as shown in Fig. 1. The detent lever 2 can thus carry out a switching function and can be moved manually or with the aid of a motor from the base position ¨ solid line ¨ shown in Fig. 1 to the displaced position ¨ dashed line ¨ as described and back again.
In principle, the embodiments of Fig. 4 and 5 operate in the same manner as already explained with reference to Fig. 1 to 3. The main difference compared to the versions shown in Fig. 1 to 3 is that according to the embodiments shown in Fig. 4 and 5 the detent spring 5 and the detent lever 2 are arranged at an angle to each other.
The detent spring 5 designed in this case as a spring washer 5, exerts a spring force F
extending perpendicularly in relation to the plane defined by the detent lever 2. Also, in the versions shown in Fig. 4 and 5, the detent spring 5 is also not formed on the fixed lever 1 but is connected to the fixed lever 1, i.e. via a rotary axis 3. The design is actually such that in the versions shown in Fig. 4 and 5 the rotary axis 3 is designed as a connecting axis acted upon by the spring washer 5 for pivotable mounting of the detent lever 2 on the fixed lever 1.
The detent spring or the spring washer 5 ensure that the detent lever 2 is acted upon in axial direction of the rotary axis 3 with the spring force F generated by said spring or washer. In this case, the detent spring 5 thus produces an axial force, acting on the detent lever 2 in the manner indicated in Fig. 4. A change of the different detent positions of the detent lever 2 compared to the fixed lever 1 requires for the detent lever 2 to be acted upon by the switching force F5, acting in the embodiment shown in Fig. 4 on the end opposed to the one projection 11. The projection 11 on the detent lever 2 does indeed cooperate again with a stop edge 6 on the fixed lever 1.
As apparent from Fig. 5 the embodiment contains two opposing stop edges 6, defined on the respective longitudinal edges of the longitudinally extending fixed lever 1.
In order for the detent lever 2 to be moved from its solid line position shown in Fig. 5 or its first detent position to the dashed position or second detent position, switching force F, must be applied to the end of the detent lever 2 opposite the projection 11, so that the projection 11 can be "lifted" over the fixed lever 1 after which it rests or can rest on the other opposing stop edge 6. In this case, at least two detent positions, as shown in Fig. 5, can be defined. Naturally also more than two detent positions are feasible.
Fig. 5 shows that the displaced position of the detent lever 2 ¨ shown by the dotted line ¨is again able to act upon the release lever 4. This is not possible if the detent lever 2 is in the base position ¨ indicated by the solid line. In this way a quick release function can again be provided, as already described in detail with reference to the version shown in Fig. 1 to 3. Naturally the invention is not restricted to this, as the decisive factor is generally the cooperation between the two levers 1, 2¨
irrespective of their function.
It is, however, also possible and feasible that the detent spring and the detent lever are arranged on different planes. In this case, the detent spring and the detent lever thus describe different planes, regularly arranged to each other at an angle.
In most cases it has proven to be advantageous in this context for the detent spring and the detent lever to be arranged perpendicularly to each other. This means that in this situation the detent spring exerts a spring force perpendicular to the plane formed by the detent lever.
A particularly cost effective and well functioning solution is characterized by the detent lever being mounted on the fixing lever in a rotary axis. The detent spring is arranged in the area of the rotary axis. In this situation, the detent spring ensures in case of the detent spring and detent lever being arranged on the same plane that the detent spring acts upon the detent lever with a perpendicular force in relation to the axial direction of the rotary axis. In contrast, the arrangement of the detent spring and detent lever on different planes, in particular their perpendicular arrangement to each other, cause the detent spring to act on the detent lever with an axial force.
In this case the spring force exerted by the detent spring acts in axial direction of the rotary axis. In general, the axial force and the force perpendicular to the axial direction of the rotary axis can also at the same time be applied to the detent lever.
In a preferred embodiment, the detent spring is a leaf spring. In this case the first one lever or fixed lever has an L-shaped cross section with the detent spring being arranged on an L-leg. As a result, the one first lever or fixed lever and the detent spring can be produced at the same time, which is particularly cost effective.
The detent contour can be a detent recess at least partially accommodating the leaf spring. The detent recess then also provides a stop in most cases. This stop represents a first detent position. In addition, at least another second stop can be provided, corresponding to a further detent position of the detent lever in relation to the fixed lever.
As part of an alternative method, the detent spring can also be a spring washer. A coil spring containing several such spring washers can also be provided in this context. In this case, the detent contour is typically designed as a stop edge interacting with the projection on the detent lever. The stop edge is located on the fixed lever, whilst the projection on the detent lever interacts with this stop edge on the fixed lever. The abutting of the projection on the detent lever against the stop edge of the fixed lever corresponds to a first detent position. A further second detent position can be assumed by the detent lever when a further stop edge is being used on the fixed lever.
Where the fixed lever is a longitudinal strip-like lever, the two longitudinal edges of the lever are each available as a stop edge for the first and second detent position.
As part of the invention, the detent lever is designed to assume at least three different detent positions. In this context it has proven to be advantageous if the detent spring and the detent lever are arranged on the same plane. This then allows the option of having the leaf spring or detent spring formed on one L-leg of the fixed lever cooperate with one polygon-like contour at the end of the detent lever.
Depending on the number of edges of this polygon-like contour or polygon structure, any number of detent positions between the detent lever and the fixed lever can be provided in theory. Each detent position corresponds to one edge of the leaf spring abutting against the polygon structure. In principle this polygon structure can also be combined with a spring washer as a detent spring. In this case it is feasible that the spring washer contains axial webs spanning the polygon structure and that each detent position corresponds to the polygon structure being, as it were, turned in relation to the finger-like spanning axial webs.
Where the detent lever assumes two or more detent positions compared to the fixed lever it has proven to be advantageous, if at least one of the detent positions can solely and exclusively be fixed with the detent spring. This means that in this case the detent position is solely defined by the cooperation between the detent spring and the detent contour ¨ without additional stop.
At least one of the several detent positions can, on the other hand, be fixed with the aid of the detent spring as well as with the aid of a stop. In this case it is on one hand the cooperation between the detent spring and the stop contour and, on the other hand, the stop and the detent lever as a whole that ensure that the detent lever assumes the respective detent position. Generally it is, of course also feasible that all detent positions of the detent lever can only be fixed in relation to the fixed lever by means of the detent spring. Also, all detent positions can only be defined due to the fact that the detent spring and the respective associated stop ensure that the detent lever assumes its desired detent position in relation to the fixed lever.
Preferably, the detent lever is an unlocking lever and, in particular, a quick release lever. In this case the detent lever can be part of an unlocking lever chain.
In contrast, the fixed lever is generally part of the actuating lever mechanism. To implement the quick release function, the detent lever is pivoted into a displaced position or second detent position compared to the first detent position or base position. This operation can be motor driven or manual. As a result of the quick release lever or detent lever assuming this displaced position, a release lever acting upon a locking mechanism can, for instance, be directly displaced via the activation lever chain so that the locking mechanism is opened without hardly any delay. The whole operation is quick, works reliably and is reproducible as the base position and displaced position of the detent lever or of the quick release lever is correctly and reproducibly assumed as a result of the cooperation with the detent spring. These are the main advantages.
Below, the invention is explained in detail with reference to a drawing showing only one embodiment, in which:
Fig.1 shows a first version of the motor vehicle door lock of the invention, Fig. 2 shows a section along line A-A of the object of Fig. 1, Fig. 3 shows an enlarged view of a modified embodiment of Fig. 1, Fig.4 shows a longitudinal section of the second version of the motor vehicle door lock of the invention and Fig. 5 shows a top view of the version of Fig. 4.
The figures show a motor vehicle door lock containing an actuating lever mechanism 1 and an unlocking lever mechanism 2. The example only shows a first lever or fixed lever 1 of the actuating lever mechanism 1 whilst the locking lever mechanism 2 is also only represented by a second lever 2. In the actual installed situation ¨
not shown in detail - the actuating lever mechanism 1 and the locking lever mechanism 2 contain also other levers, not identified further, which are of no importance in the present case.
As usual, the actuating lever mechanism 1 is typically mechanically connected to a handle, e.g. an internal door handle and/or external door handle. Activation of the handle for opening a motor vehicle door belonging to the shown motor vehicle door lock results in the first lever or fixed lever 1 being pivoted around a respective rotary axis 3 in counter clockwise direction in the embodiment shown in Fig. 1, as indicated by an arrow. During these pivoting movements, the detent lever 2 mounted on the fixed lever 1 in the rotary axis 3, does not reach the indicated release lever 4.
When, on the other hand, the detent lever 2 assumes its displaced position or second detent position in comparison to its first detent position or base position ¨
shown by a solid line ¨ in comparison to the fixed lever 1 ¨ shown by a dashed line ¨ the already discussed pivoting movement of the fixed lever 1 triggered by the handle, causes the release lever 4 to be acted upon. As a result, the handle is now able to open a locking mechanism ¨ not shown in detail - by means of a release lever 4. The triggering lever 4 does, indeed act on a pawl ¨ not shown ¨ lifting it off the rotary catch.
The rotary catch opens with the aid of the spring and releases a previously retained locking pin.
As a result, the motor vehicle door can be directly opened.
The described process corresponds to a quick release which is achieved manually and/or with the aid of a motor, by the detent lever 2 being moved in the example from its base position ¨ shown by a solid line ¨ to its deflected position ¨ shown by a dashed line. Both levers 1, 2 are indeed coupled to one another in at least two different relative positions, the base position and the deflected position, as described.
This coupling is a detent coupling, as the first lever or fixed lever 1 contains a connected detent spring 5. The detent spring 5 is arranged to cooperate with at least one detent contour 6 at the other second lever or detent lever 2. In the embodiments shown in Fig. 1 to 3, the detent spring 5 is formed on the first lever or fixed lever 1.
The detent spring 5 and the first lever 1 do actually form a single-part component.
From the respective sectional view of Fig. 2 it is also apparent that the fixed lever 1 together with the single-piece detent spring 5 forms an overall L-shaped lever 1, 5 in cross section. The fixed lever 1 defines the longer L-leg, whilst the detent spring 5 is arranged on the shorter Lleg. In this way, the fixed lever 1 and the detent spring 5 can be produced in one and the same operation, keeping costs to a minimum. The detent spring 5 is also designed as a leaf spring 5.
It is apparent that the detent spring 5 and the detent lever 2 are arranged on the same plane in the example shown in Fig. 1 to 3. This means that the spring force F
exerted by the detent spring 5 acts in the direction of the plane defined by detent lever 2. This is indicated in Fig. 1 by a respective force arrow F for the spring force F
exerted by the detent spring 5.
The aforementioned detent contour 6 on the detent lever 2 corresponds to the detent spring or leaf spring 5. In the embodiment shown in Fig. 1 to 3 the detent spring 5 or leaf spring 5 has a rectangular cross section, so that the contour 6 also has a square form. As a result, the detent contour 6 also forms a stop 7 for the front end of the leaf spring 5.
The stop 7 and the cooperation between the detent spring 5 and the detent lever 2 define the first detent position or the base position of the detent lever 2 ¨
shown by a solid line - in Fig. 1 in relation to the fixed lever 1. When the detent lever 2 is pivoted out of this position into the deflected position shown by the dashed line, with the effects already described above, a further stop 8 is provided, which again with the cooperation between the detent spring 5 and the detent contour 6 ensures that the defined displaced position of the detent lever 2 is taken up. The stop 8 ¨
like the detent spring 5 ¨ is formed on the fixed lever 1 (single component).
Manufacture is therefore simple and quick. For actual functioning it suffices to define the fixed lever 1 together with the bevelled detent spring 5 and the bevelled and also connected stop 8 and then to only pivotally connect the detent lever 2 with the help of the rotary axis 3 to the fixed lever 1.
Fig. 3 shows that the detent lever 2 is not only arranged and suited to assume the two detent positions shown in Fig. 1, i.e. the base position and the displaced position. The detent lever 2 can also assume three or more different detent positions. For this purpose the detent lever 2 has, in the version shown in Fig. 3, one polygon contour 9 with several edges 10 in the area of its end on the rotation axis side.
Depending on the number of edges 10 of the polygon contour 9, three, four or even more different detent positions of the detent lever 2 can be defined and arranged in relation to the fixed lever 1. In the example, each detent position corresponds to the detent lever 2 being only fixed with the detent spring 5. In other words, no additional stops are used, although this is of course possible and is part of the invention. In the described versions of Fig. 1 to 3 the detent spring 5 and the detent lever 2 are, as explained, arranged on the same plane. The design is such that the detent spring 5 acts on the detent lever 2 with the force or spring force F extending perpendicularly to the axial direction of the rotary axis 3, as shown in Fig. 1. The detent lever 2 can thus carry out a switching function and can be moved manually or with the aid of a motor from the base position ¨ solid line ¨ shown in Fig. 1 to the displaced position ¨ dashed line ¨ as described and back again.
In principle, the embodiments of Fig. 4 and 5 operate in the same manner as already explained with reference to Fig. 1 to 3. The main difference compared to the versions shown in Fig. 1 to 3 is that according to the embodiments shown in Fig. 4 and 5 the detent spring 5 and the detent lever 2 are arranged at an angle to each other.
The detent spring 5 designed in this case as a spring washer 5, exerts a spring force F
extending perpendicularly in relation to the plane defined by the detent lever 2. Also, in the versions shown in Fig. 4 and 5, the detent spring 5 is also not formed on the fixed lever 1 but is connected to the fixed lever 1, i.e. via a rotary axis 3. The design is actually such that in the versions shown in Fig. 4 and 5 the rotary axis 3 is designed as a connecting axis acted upon by the spring washer 5 for pivotable mounting of the detent lever 2 on the fixed lever 1.
The detent spring or the spring washer 5 ensure that the detent lever 2 is acted upon in axial direction of the rotary axis 3 with the spring force F generated by said spring or washer. In this case, the detent spring 5 thus produces an axial force, acting on the detent lever 2 in the manner indicated in Fig. 4. A change of the different detent positions of the detent lever 2 compared to the fixed lever 1 requires for the detent lever 2 to be acted upon by the switching force F5, acting in the embodiment shown in Fig. 4 on the end opposed to the one projection 11. The projection 11 on the detent lever 2 does indeed cooperate again with a stop edge 6 on the fixed lever 1.
As apparent from Fig. 5 the embodiment contains two opposing stop edges 6, defined on the respective longitudinal edges of the longitudinally extending fixed lever 1.
In order for the detent lever 2 to be moved from its solid line position shown in Fig. 5 or its first detent position to the dashed position or second detent position, switching force F, must be applied to the end of the detent lever 2 opposite the projection 11, so that the projection 11 can be "lifted" over the fixed lever 1 after which it rests or can rest on the other opposing stop edge 6. In this case, at least two detent positions, as shown in Fig. 5, can be defined. Naturally also more than two detent positions are feasible.
Fig. 5 shows that the displaced position of the detent lever 2 ¨ shown by the dotted line ¨is again able to act upon the release lever 4. This is not possible if the detent lever 2 is in the base position ¨ indicated by the solid line. In this way a quick release function can again be provided, as already described in detail with reference to the version shown in Fig. 1 to 3. Naturally the invention is not restricted to this, as the decisive factor is generally the cooperation between the two levers 1, 2¨
irrespective of their function.
