Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to a cable control device, including a flexible cable that translates inside a protective sheath, a so-called control cable.

[0002]

2. Description of the Related Art Such a cable control device is used in many fields, particularly in the field of automobiles, for controlling the opening / closing of a door or a trunk or transmitting commands sent from a shift lever or a pedal. .

[0003] Cables are often actuated by operating devices that include a swing joint. The swing joint has one end coupled to the operation member and the other end including a coupling means for connecting to the control cable, and converts the rotational force of the control member and the swing joint into a pulling force for translating the control cable.

[0004] Such an operating system including a swing joint is quite satisfactory, and in particular can exert a high stress on the cable depending on the ratio of the lever arm of the swing joint.

However, these devices have the disadvantage of requiring a relatively large utilization space in proportion to the stroke of the swing joint, so that these devices are not suitable for use in narrow environments.

[0006]

Therefore, it is necessary to provide a control cable operating device that translates in the axial direction and has a smaller external dimension than the operating device of the prior art.

[0007]

In order to achieve this object, the present invention is directed to an operating device for an axially translating control cable, comprising a rotating operating member and a control cable. And a means for converting the rotational movement of the operating member into the movement of the coupling means for translating the cable.

According to the present invention, the coupling means has a linear translational movement, the means for converting the movement of the operating member comprises a cam defining at least one substantially spiral cam track, and a cam follower cooperating with the cam track. It is characterized by including.

By implementing the helical mechanism of the cam and the cam follower, the translation of the coupling means connected to the control cable, most often to one end of the control cable, directly translates the rotational movement of the operating member. There is an advantage that it can be converted.

According to a preferred feature of the invention, the direction of translation of the coupling means substantially coincides with the axis of rotation of the operating means. With such a configuration of the present invention, it is possible to minimize the outer dimensions of the entire operation device.

According to another feature of the invention, the conversion means is arranged such that the control cable is pulled at least once when the operating member is rotated once.

According to another feature of the present invention, one rotation of the operating member in one direction causes the coupling member to be driven in translation, while rotating the operating member in the opposite direction causes the coupling member to be reciprocally driven. The conversion means is configured so as not to perform a certain movement. This feature of the invention has in particular the advantage that the operating member can return to the initial position without the control cable or one end thereof returning to the initial position. In this way, it is possible to avoid applying stress that would cause the operating device to deteriorate.

According to the embodiment, the conversion means is configured to control the axis X-
X 'translates along the axis, the rotation about the axis XX' is fixed, the slider coupled to the coupling means, and the operation means coupled to rotate about the axis XX ', A translation member fixed along the axis XX ′ and coupled to the slider in at least one direction of movement by a helical connection.

In such a case, preferably, but not necessarily, the slider guides the rotation of the rotating member. Also preferably, the slider together with the control cable forms the coupling means. The slider may for example be integrally molded at one end of the control cable and connected to this end. The slider may also include, but is not limited to, for example, a receiving groove in a head coupled to the end of a control cable.
A control cable end securing means may be included.

[0015] In a preferred embodiment, the operating device according to the invention comprises a support having two pads. The deposit is
It is configured to be spaced apart from each other to guide the slider in translation, at least one of which is connected to the slider by a prismatic connection.

The slider has a prismatic head at least in part and a rotating cylindrical body about the axis XX ', and has at least one spiral groove on the surface of the body. Further, the rotating member is formed as a ring of approximately the same length, except for functional play, at a distance separating the two ferrules and has at least one internal shoulder cooperating with the spiral groove of the slider. When the ring rotates in at least one direction under the action of the operating member, the slider translates.

According to an embodiment of the present invention, the operating device according to the present invention includes means for returning the operating member to the rest position.

Furthermore, the operating device according to the invention can be used for actuation of a control cable with or without a protective sheath.

If the control cable is protected by a sheath, the device according to the invention can include means for fixing one end of the protective sheath of the control cable.

According to a preferred embodiment, but not necessarily, the means for fixing one end of the protective sheath of the control cable comprises means for adjusting the length of the protective sheath. Thus, the adjusting means can act on the relative length of the sheath to the cable or on the length of the free cable.

The accuracy of the motion transmission of the control member depends on the relative length of the sheath to the cable. Therefore, if the armor is too short, it cannot affect the entire amplitude of the movement of the controlled member. If the armor is too long, the control cable moves but does not act on the member to be controlled. May remain significantly.

The adjusting means preferably has a semi-automatic function. For this purpose, the adjusting means is open at both ends for the passage of the control cable and is adapted to be connected to the support of the device, and has a hollow body fixed in translation and rotation with respect to the support, and an axis X. X 'is an extension of X', both ends are open for passing a cable, and a groove for receiving one end of a protective sheath is provided at one end, and rotates in the axial direction, and moves between the maximum extension position and the contraction position. Axis X-
A hollow sheath tube attached to the body so as to perform axial translation parallel to X ', a spring interposed between the body and the sheath tube to bring the sheath tube into an extended position, It includes translational blocking means for the sheath tube, which can be shifted from the unblocked state, that is, the so-called translatable state, to the blocked state by an axial rotation movement, and rotation driving means for the sheath tube.

Preferably, the translation blocking means is reversible.

The translation blocking means can be configured in any suitable direction. Preferably, the translation blocking means comprises at least one rack provided on one of the two elements of the sheath tube or body and at least one tooth provided on the other element and cooperating with the rack. Including.

According to another embodiment of the present invention, the translation blocking means is provided on at least one rack provided on a part of the inner wall of the main body and on a part of the outer wall of the sheath tube,
A rack configured by the body and at least one other rack cooperating therewith blocks translation of the sheath relative to the body.

According to a feature of the present invention, the translation blocking means is configured to axially move the sheath tube in the direction of the extension movement or the contraction movement when transitioning from the unblocked state to the blocked state. In the case of a stretching movement, such a configuration of the present invention can exert a compressive stress on the protective sheath. Conversely, in the case of a contraction movement, this configuration of the invention allows the control cable to have a certain play corresponding to the movement of the sheath tube.

Of course, according to the present invention, it is possible to configure a translation blocking means for the sheath tube so that the sheath tube does not move at all when the block is changed from the unblocked state to the blocked state.

In a preferred embodiment, in order to automatically use the length adjusting means of the sheath, the rotation driving of the sheath tube is performed so that when the operating member is rotated in the direction of pulling the cable, the blocking means shifts to the blocking state. Configure means.

In order to perform translational blocking of the sheath tube only when the operating device according to the present invention is used for the first time, the driving means is configured to rotate the sheath tube only at the first rotation of the operating member. Thus, the present invention prevents the translational block of the sheath tube from being unblocked and the length of the sheath not being adjustable if the operating member subsequently rotates.

However, there is a non-operation stroke in which the operating member does not act on the control cable, so that each time the operating member returns to the initial position, the translation block of the sheath tube is released, and the length of the sheath can be automatically adjusted. Is also good. Thereafter, when acting on the operating member to pull the control cable, one can consider performing a translational block of the sheath tube before pulling the cable. Thus, the sheath tube is blocked during the inactive stroke of the operating member, and the control cable is pulled only after the translation block of the sheath tube.

The means for rotationally driving the sheath can be constructed in any suitable way.

According to a preferred embodiment, the drive means comprises a finger connected to the sheath tube and at least one drive stop connected to the operating member. The drive stopper is
The sheath tube is rotationally driven by cooperating with the sheath tube fingers.

According to another preferred feature of the invention, although not necessary, the operating device further comprises means for damping the axial rotation of the sheath tube relative to the body.

Before installing the operating device on the support or on the assembly constituting the support, the rotation of the sheath tube from the unblocking position to the blocking position in order to prevent accidental blocking of the translation of the sheath tube. The braking means is configured so as to apply resistance to the braking force.

Similarly, in order to prevent the translation of the sheath tube from being unblocked undesirably, in particular by vibratory action, the braking means is designed to similarly provide resistance to the unblocking of the translation of the sheath tube.

The braking means can be constructed in any suitable way. For example, but not by way of limitation, it can be constituted by at least one convex or concave braking element coupled to the sheath tube. The braking element is configured to cooperate with an engaging shaped braking element coupled to the body.

According to a feature of the present invention, the hollow body of the armor length adjusting means forms a pad for guiding the coupling member.

The present invention is also directed to a device for controlling a movable member by means of a translation control cable, which is connected at one end to the movable member and at the other end to the operating device according to the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a control device 1 according to the present invention. The device is configured to activate a control cable 2 that translates axially. For this purpose, the device 1 includes an operating member 3 that rotates, such as a lever. The operating device 1 also comprises a movable coupling means 4 with the control cable 2 and means 5 for converting the rotational movement of the operating member 3 into a movement of the coupling means 4 for driving the cable 2 in translation. The means 5 for converting the rotational movement of the operating member 3 into a translation of the movable coupling means 4 means the entire element that performs this conversion, supports each component of the operating device or directly participates in such a movement conversion.

According to a main feature of the invention, the motion conversion means 5 of the operating member comprises a cam 6 defining at least one substantially spiral cam track, and a cam follower 7 cooperating with the cam track. In this case, the cam track is configured to connect the cam 6 and the cam follower 7 by a helical connection in at least one direction in which the cam follower 7 translates.

According to this example, the connecting means 4 is used for the slider 1
0 and the cam follower 7 forms the main body of the slider 10. As will be described later, the slider 10 translates along the XX 'axis according to its function, and the rotation is fixed relative to this axis. Thus, the device 1 includes a support 11 for guiding the slider 10. The support 11 may be of any suitable type, for example, a structural or functional element of an assembly incorporating the operating device according to the invention. In order to hold and guide the slider 10, the support 11 includes two pads 12 that are separated from each other by a distance L. Each paddle 12 has, of course, a hole through which the slider 10 passes.

In order to block the rotation of the slider about the translation axis XX ', at least one of the two supports is connected to the slider by a prismatic connection. According to the illustrated example, such a prismatic connection is obtained by engaging the shape between the slider head 4, which is at least partially prismatic, and the corresponding boring 13 of the pad 12. Can be According to the illustrated example, the slider 10
Is integrally molded at the end of the cable 2 so as to be finally joined to the cable 2.

The operating device 1 further includes a rotating member connected to the lever 3 to form the cam 6. The rotating member 6 is formed as a ring having a distance L ′ approximately equal to the distance L separating the two fins 12, except for the functional play 13. The rotating member 6 has a central conduit 14 that houses the main body of the slider 10. The central conduit 14 is substantially cylindrical in rotation and includes at its center two shoulders 15 defining two helical cam tracks 16. Of course, the central conduit 14 of the ring may define one helical cam track with one shoulder, or vice versa.
It may have more than one shoulder and define the same number of cam tracks. The shoulder 15 is configured to cooperate with two spiral grooves 17 provided on the surface of the main body 7 of the slider. On the other hand, the slider body 7 has a substantially rotating cylindrical shape about the axis XX '. Cam ring 6
Has only one helical cam track, there is only one helical groove 17 on the slider 10, especially the body 7 forming the cam follower. Similarly, when the cam 6 defines two or more cam tracks, the cam follower 7 includes the same number of spiral grooves as the cam tracks. According to the example shown, the spiral groove 17
Are configured to protrude from the surface of the main body 7. These spiral grooves can be formed in the main body 7 as cavities.

When the cable 2 is protected by the protective sheath 20, the operating device 1 includes a fixing means 21 at one end of the sheath 20. According to the illustrated example, the fixing means 21 is configured as the mounting groove 22 of the fixing head 23 connected to one end of the protective sheath 20.

When the cable 2 must be acted on, the operator rotates the lever 3 in the direction of the arrow F1, and the cam ring 6 rotates about the axis XX '. When the translation of the cam ring 6 is fixed between the two supports 12, this rotation of the cam 6 causes the slider 10 to move in the direction of the arrow F 2 corresponding to the pulling direction of the cable 2.
Along the axis XX ′. Such translation of the slider 10 is, of course, caused by the spiral groove 17 of the slider 10.
And the shoulder 15 of the cam ring 6 cooperate. The slider has two functions: the transfer of movement from the lever to the cable, and the cam ring 6 and thus the lever 3.
And a rotation guide. Thus, since the rotation axis of the operating member coincides with the translation axis of the cable 2, the operating device 1 according to the present invention is significantly smaller in external dimensions than the operating device according to the prior art.

According to the example shown, the shoulder 1 of the cam
The connection between the slider 5 and the spiral groove 7 of the slider can be regarded as a kind of planar support, and the operation member 3 is rotated in the direction of arrow F3 in FIG. Can return to the initial position. Thus, the slider 10 can remain in the pulled position shown in FIG. 4 and only later returns to the initial position shown in FIG. With this configuration of the present invention, it is possible to prevent the cable 2 from being stressed when the operating member 3 returns to the rest position. This is particularly advantageous if the device controlled by the cable 2 is a locking system which is left unlocked independently of the actuation of the operating member 3.

It moves to the blocked state shown in FIG.
It is configured as follows.

In order to be able to move the sheath tube from the unblocking position D to the blocking position B, the adjusting means further comprises a rotational drive means 40 for the sheath tube 32. According to the example shown, the rotational drive means 40 comprises a finger 41 connected to the sheath tube 32, which finger extends axially from the end of the sheath tube oriented towards the operating member 3. At this time, the finger 41 cooperates with the stopper 42 connected to the operation member 3.

According to the illustrated example, the stopper 42
It is defined by the edge of the window provided in the ring 6. The stopper 42 and the finger 41 are configured to shift the sheath tube to the block position when operating the operation member 3 for the first time, as described later.

The above-described device according to the invention shown in FIGS. 6 to 9 is used as follows.

After assembling the components of the apparatus, screws or rivets are arranged in the holes 30 to fix the supports 12 ₁ and 12 ₂ to the support 11.

When the operating device 1 is installed, the length adjusting means 30 of the exterior 20 is preferably at the block release position shown in FIG. 8, and the fingers 41 of the driving means 40 are indicated by broken lines in FIG. Are arranged as shown.

[0063] operating device 1, so as not to shift to folding Ashiku block position when variously operating the device prior to assembly, not but preferably are but need for straps 12 ₁ Means 50 for damping the rotational movement of the sheath tube 32 is included.

The braking means 50 can be constructed in any suitable way, and according to the example shown, the braking means 50 comprises a stop S1. Stopper S1 is coupled to the sleeve pipe 32, in the unblocking position, is engaged in a groove 52 in the axial direction provided on the straps or body 12 _1. Stopper 51

Rotation movement is hindered, and especially the sheath tube 3 is located at the translation block position.
When 2 attempts to migrate, it exerts resistance.

Thus, the sheath tube 32 can be moved to the block position only when the worker in charge of the assembly moves intentionally.

Therefore, in the initial assembled state, the sheath tube 32 can be translated by the pad 12, and the position of the sheath tube with respect to the pad is adjusted according to the length of the sheath 20 and the stress exerted by the spring 34. Can be. When the operating member 3 is first pulled in the direction of arrow F5, the ring 6 supporting the stopper 42

Corresponds to the block position B shown in FIG. In the blocking position, the translation of the sheath tube 32 is blocked because the teeth 37 cooperate with the rack 36. In order to keep the sheath tube 32 in the blocking position, the braking means further comprises a second axial groove 53 in which the stopper S1 is engaged in the blocking position. Thus, the braking means 50 exerts a resistance to the rotational movement of the sheath tube from the block position B. This advantageous arrangement of the invention ensures that the blocking of the sheath tube 32 does not inadvertently become unblocked, especially by vibratory action.

Further, the ring 6 defining the stopper 42
Are sufficiently dimensioned that normal movement of the operating member 3 does not cause translational unblocking of the sheath tube 32.

Thus, the adjusting means 31 is configured to be blocked after the initial operation of the operating member 3, after which it is no longer unblocked.

According to a variant embodiment, not shown,
The blocking means 35 is configured to translate the sheath tube 32 in the axial direction at the time of transition from the unblocked state to the blocked state. To this end, the rack 36 and preferably the teeth 37 also have a helical profile, the pitch of which determines the displacement value of the sheath tube 32. The orientation of the profile of the rack 36 and the teeth 37 is then
It depends on the desired direction of movement to extend or contract the sheath tube 32.

According to the above example, the rotating member 6 is attached to the slider 10. However, such an assembly
It is not necessary for the implementation of the operating device according to the invention.

Therefore, FIG. 10 shows another embodiment of the operating device according to the present invention in which the rotating member 6 is fitted on the slider 10. According to this example, the entire shape of the slider 10 is substantially prismatic, and in the illustrated example, it is a parallelepiped. The slider 10 is provided with two supports 1 of the support 11.
2 is guided in translation along the axis XX ′. The slider 10 further includes a cylindrical central bore 130 having an axis XX ′.

Further, according to this example, the rotating member 6
The slider has a generally rotating cylindrical body having an axis XX ′ configured to engage the borebore 130.
The rotating member 6 includes an operating head 132 coupled to the operating lever 3 at the end of the main body 131 opposite the slider 10. In order to fix the translation of the rotating member 6, the head 132
Has a peripheral groove 133 in which, in the example shown, at least two stops 134 which are connected to the support 1 are engaged in this groove.

The boring has two spiral grooves 135 and 136 on its wall to convert the rotation of the rotating member 6 into the translation of the slider 10 by the action of the lever 3. Spiral groove 13
5, 136 are configured to cooperate with two pawls 137, 138 supported by the body 31 of the rotating member 6.

According to this embodiment, when the claw moves in the groove, the cable 2 can be pulled by the rotation of the operation member 3 and the control cable can be pushed by the rotation in the opposite direction. Therefore, there is reciprocity between the translation of the slider and the rotation of the operating member.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.
