Description

<Desc / Clms Page number 1>

 The present invention relates to the technical field of cable control devices generally comprising a flexible cable, called control cable, movable inside a protective sheath.

 Such cable control devices are used in many fields such as in particular the automotive field for, for example, controlling the opening of doors or hoods or even controlling various adjustment mechanisms.

 Most often, the control cable has, at its end, a sphere or a stop intended to act on a lever of the member to be controlled. In order to ensure normal operation of the device, it is necessary to be able to immobilize the protective sheath relative to the support of the member to be controlled. To this end, it is known to use sheath ends intended to be immobilized by means of screws or rivets on the support of the member to be controlled. However, if the screws or the rivets make it possible to ensure effective immobilization and resistance of the sheath end piece on the support, such fastening devices have the disadvantage of involving an assembly operation involving the use of a special tools and requiring labor time that is difficult to reduce.

 However, these two aspects of using a special tool and of incompressible assembly time can appear to be prohibitive in certain applications where maximum efficiency is sought by eliminating, as far as possible, the use of tools so as to reduce assembly times to a minimum.

 Thus, the invention aims to propose a new device for fixing the end of a protective sheath of a control cable which requires no special tools for its implementation and which has a particularly short assembly time.

 Thus, in order to achieve these objectives, the invention relates to a device for fixing, on a support, the end of a protective sheath of a control cable. This fixing device comprises: a body intended to be fixed to one end of the protective sheath and open at one end at least for the passage of the cable, - means for fixing the body to the support.

<Desc / Clms Page number 2>

 According to the invention, this fixing device is characterized in that the fixing means comprise: - a hooking member intended to fit at least one hooking edge of the support, - a mobile locking member intended to cooperate, in a so-called locking position, with the support to prevent the release of the attachment member. The realization of the fixing means, in a hooking member and a locking member, ensures a particularly rapid mounting of the fixing device. Indeed, the mounting operation is carried out in two stages, namely fitting of the attachment member on the support and then locking of the movement of the device by the movable member engaged in abutment on the support. In addition, this assembly does not require any special tools.

 According to a preferred embodiment, the movement of the locking member is reversible, so that it is possible to disassemble the fixing device.

 According to a characteristic of the invention, the fastening member comprises: - the fastening member comprises a fastening head connected to the body by an arm and intended to be engaged in a lumen of the support to fit an edge of the lumen, - and the locking member is intended to be engaged in the lumen together with the arm and adapted to, after its engagement in the lumen, lock the movements of the body relative to the support.

 According to another characteristic of the invention, the locking member is integral with the body and movable relative to the body, between an unlocked position and the locking position. In this way, the locking member remains linked to the body of the device during all the stages of the implementation of the device, from storage to mounting, which guarantees, to the mounting operator, to always have a device complete fixing.

 According to another characteristic of the invention, the fixing device comprises means for braking the movement of the locking member relative to the body.

<Desc / Clms Page number 3>

 Preferably but not strictly necessary, the braking means are then adapted to offer resistance to the passage of the locking member in the locking position from the unlocked position. This advantageous characteristic of the invention makes it possible to prevent untimely movements of the locking member, in particular during the manipulation of the fixing device, so that the latter always remains in the unlocked configuration until it is mounted on a support. During assembly, the operator then voluntarily exerts, on the locking member, a force greater than the resistance offered by the braking means, so as to move the locking member from the unlocked position to the position of locking.

 According to a preferred embodiment of the device according to the invention, the locking member forms a slide movable in translation in a direction substantially perpendicular to the direction of extension of the protective sheath.

 Insofar as the precision of the action of the control cable is most often a function of the relative length of the protective sheath relative to the cable, the device according to the invention also comprises, preferably but not strictly necessary, means for adjusting the length of the sheath.

 Preferably, the means for adjusting the length of the sheath or the relative position of the end of the sheath relative to the member to be controlled have semi-automatic operation.

 To this end, the means for adjusting the length of the sheath comprise: - a slide in which is intended to be inserted one end of the sheath, which is open at one end at least for the passage of the cable and which is movable by relative to the body in axial translation in the body, between a position of maximum extension and a retraction position, - a spring interposed between the body and the slider to control the slider in the extended position, - means for blocking the translation of the slide relative to the body.

<Desc / Clms Page number 4>

 In a preferred but not strictly necessary embodiment, in order to reduce, as much as possible, the operations necessary for correct mounting of the device according to the invention, the means for blocking the adjustment of the length of the sheath are actuated by the locking member, so that in position of the locking member, the movement of the slide is blocked.

 In the case where the locking member is formed by a slide movable in translation in a direction substantially perpendicular to the direction of extension of the protective sheath, the locking means preferably, but not strictly necessary: - a rack fitted on the slide, - and at least one tooth fitted on the drawer and arranged so as, on the one hand, to be released from the rack in the unlocked position of the drawer and, on the other hand, to cooperate with the rack to block the movement of the slide in the drawer locking position.

 According to an alternative embodiment of the invention, the means for blocking the translation of the slide, and more particularly the rack of the slide as well as the tooth of the drawer, are suitable for, when they pass from the unlocked position to the locked position , cause an axial translation of the slider either in the direction of an extension, or in the direction of a retraction of the slider. In the case of an extension movement, this arrangement of the invention makes it possible to induce a prestressing of the sheath which allows compensation for the settlement of the sheath after the first maneuvers of the cable. On the other hand, in the case of a retraction movement of the sheath, this arrangement of the invention makes it possible to give the cable an operating clearance corresponding to the value of the displacement of the sheath by the locking means.

 The invention also relates to a cable control device comprising a movable cable in a protective sheath. According to the invention, the control device further comprises a fixing device according to the invention, the body of which is integral with one end of the protective sheath.

 In a preferred but nonlimiting application, the invention also relates to a device for transmitting movements between, on the one hand, a control cable movable in axial translation inside a

<Desc / Clms Page number 5>

 protective sheath and, on the other hand, a rotating member movable in axial rotation relative to a support.

 According to the invention, the transmission device further comprises a fixing device according to the invention, the body of which is integral with one end of the protective sheath and carries a lever, movable in rotation relative to the body, comprising, d on the one hand, means for coupling in rotation with the rotating member and, on the other hand, means for connecting with one end of the cable.

 According to the invention, the means for coupling in rotation, between the lever of the transmission device and the rotating member to be controlled can be produced in any suitable manner.

 It could, for example, be envisaged that the control means comprise at least two fingers integral with the lever and intended to come to engage in complementary housings offered by the rotating member to be controlled. Thus, the lever of the transmission device according to the invention would include coupling means which could be qualified as male intended to cooperate with complementary female means carried by the rotating member.

 In the same way, the coupling means carried by the lever of the transmission device according to the invention can be produced in the form of female coupling means intended to receive additional male means carried by the rotating member to be controlled.

Thus, according to a preferred embodiment of the invention, the coupling means comprise a bore which is arranged in the lever and whose axis is coincident with the axis of rotation of the lever. The bore of the lever is then intended to receive a complementary part of the rotating member to be controlled.

 According to a characteristic of the invention, the connecting means, between the control cable and the lever, are adapted to ensure reciprocity between the movements of the control cable and the movements of the lever.

 In this regard, it should be noted that the transmission device according to the invention can be used either to ensure the transmission by the control cable of a movement to the rotating member, or on the contrary to ensure the transmission by the body rotating with a movement to the control cable.

<Desc / Clms Page number 6>

 According to a characteristic of the invention, the connecting means, carried by the lever, comprise a cavity for receiving a fixing head secured to the end of the cable.

 Of course, the connection means between the cable and the lever could be produced in a completely different way and it could also be envisaged that the lever is directly overmolded on the connection cable or on a crimped head, carried by the end. of the last.

 According to another characteristic of the invention, the lever comprises a groove for winding and guiding the cable. This winding groove can then be used to either guarantee strict proportionality between the movement of the cable and the rotation of the lever, or on the contrary to induce a transmission ratio between the movement of the cable and that of the lever. Similarly, the winding groove can make it possible to vary the force exerted by the cable or transmitted to the latter as a function of the position of the lever.

 Various other characteristics of the invention emerge from the description above, made with reference to the appended drawings which illustrate various non-limiting embodiments of a device for fixing the end of a protective sheath of a control cable according to the invention and a cable control device using this fixing device.

 Figure 1 is a perspective view of a preferred embodiment of a fixing device according to the invention.

 Figure 2 is a section along the plane II-II of Figure 1 showing the device according to the invention in the unlocked position before fixing on its support.

 Figures 3 and 4 are sections similar to Figure 2 showing different phases of the establishment of the fixing device according to the invention.

 FIGS. 5 to 8 illustrate details of construction of constituent elements of the device according to the invention as illustrated in FIGS. 1 to 4.

 FIG. 9 illustrates an alternative embodiment of the fixing device according to the invention.

 A device according to the invention, as illustrated in Figure 1 and designated as a whole by the reference 1, is intended to allow the attachment of the end of a protective sheath 2 of a control cable

<Desc / Clms Page number 7>

 3 on a support 4. Thus, the fixing device 1 comprises a body 10 intended to be integral with one end of the protective sheath 2. The body 10 can then either be fixed directly on the end of the sheath 2 , or include a housing for receiving the end of the latter.

The body 10 is open at at least one of its ends in order to allow the passage of the control cable 3 to an operating member or a device to be controlled 6. The body 10 further comprises means 11 for fixing to the support 4, as shown in FIGS. 2 to 4.

 According to an essential characteristic of the invention, the fastening means 11 firstly comprise a fastening member 12 intended to fit a fastening edge 13 of the support 4. The fastening means 11 also comprise a member locking mobile 14, intended to cooperate in a so-called locking position more particularly illustrated in FIG. 4 with the support 4 in order to prevent the unhooking of the latching member 12. The latching member 12 and the locking member 14 can be made in any suitable manner, in particular as a function of the support 4 or of the forces that they are likely to have to bear.

 According to the example illustrated, the attachment member 12 forms a one-piece assembly with the body 10. As can be seen more particularly from FIG. 5, the attachment member 12 then has an L-shape and includes a head d 'hooking 16 connected to the body 10 by an arm 17. As will appear later, the head 16 is intended to be engaged in a slot 18 arranged in the support 4 to fit the edge 13 of the slot 18 in a groove 19 delimited by the attachment head 16, the arm 17 and the body 10.

 Like the attachment member 12, the locking member 14 can be made in any suitable manner.

 According to the example illustrated, the locking member 14 is intended to be engaged in the lumen 18 together with the arm 17, as shown in Figure 4, to lock the movements of the body 10 relative to the support and more particularly prevent disengagement of the edge 13 from the groove 19 and an exit from the attachment head 16 through the window 18.

<Desc / Clms Page number 8>

 According to the example illustrated, the locking member forms or forms an integral part of a drawer 25 secured to the body 10 and movable in translation in a direction A substantially perpendicular to the direction D of extension of the protective sheath 2. Thus , the slide 25 is movable between an unlocked position as illustrated in FIGS. 2 and 3 and the locking position as illustrated in FIGS. 1 and 4.

 According to the example illustrated, the drawer 25 has a general U-shape, a first branch of which defines the locking member 14, while the second branch 26 is formed by two parallel arms 27, as is more particularly shown in FIG. 6 The two arms 27 carry, at their ends opposite the core 28 of the drawer 25, a stop bar 30 intended to cooperate with two stop pins 31 more particularly illustrated in FIG. 7. The pins 31 and the bar 30 prevent separation between the drawer 25 and the body 10. Furthermore, the translational guidance of the drawer 25 is ensured by the engagement of the branch 14 in a passage 32 of the body 10, of complementary shape. The implementation of the fixing device 1 according to the invention is carried out as follows.

 First of all, the device is assembled, consisting in adapting the body 10 on one end of the protective sheath 2 as well as the drawer 25 on the body 10. Taking into account the implementation of the bar stop 30 cooperating with pins 31, the drawer 25 can be considered as captive relative to the body 10. Of course, the imperdability of the drawer 25 or of the locking member 14 relative to the body 10 could be achieved in a any other way.

 The assembly thus formed being in an unlocking position as illustrated in FIG. 2, the attachment member 12 is placed facing the light 18 so as to be engaged therein in the direction of the arrow F1. It should be noted that the dimensions of the window 18 and of the head 16 of the fastening member are then adapted to allow this engagement. Once the engagement has been carried out, the body 10 is moved parallel to the surface of the support 4 in the direction of the arrow F2, so as to ensure that the hooking edge 13 of the support in the groove 19 is fitted, as illustrated. in Figure 3.

 In this state, the fixing of the body 10 on the support 4 is completed by exerting pressure on the carriage in the direction of the

<Desc / Clms Page number 9>

 arrow F3 so as to engage the locking member 14 in the window 18 in the locking position as illustrated in FIG. 4. It should be noted that the link arm 17 and the locking member 14 then have dimensions in relation to those of the opening 18, so that the joint engagement of the arm 17 and the locking member 14 in the window 18 prevents any possibility of disengagement of the fastening member relative to the edge 13 of the support. Thus, the body 10 and the end of the sheath 2, which is integral therewith, are perfectly fixed on the support 4.

 According to the example illustrated, the device according to the invention has, in order to facilitate the mounting operation, means for braking the movement of the carriage adapted to avoid inadvertent movement of the latter during the handling of the device.

 According to a preferred embodiment, the braking means 30 are adapted to, on the one hand, oppose a displacement of the locking member 14 towards its locking position and, on the other hand, the displacement in direction reverse from the locked position to an unlocked position.

 The resistance to displacement from the unlocked position to the locking position makes it possible to offer the user of the device according to the invention a fixing device which remains in the unlocked position until its final assembly. Thus, the operator does not have to act on the position of the locking member 14 before mounting, it therefore results in significant time savings.

 Furthermore, the resistance to unlocking offered by the braking means makes it possible to avoid an untimely stalling of the fixing device under the effect for example of vibrations.

 According to the illustrated example, the braking means 30 are formed by a shoulder 36 carried by the bar 30. The shoulder 36 is then, in the unlocked position of the drawer 25, bearing against a complementary stop 37 offered by the body 10 The support of the shoulder 36 on the stop 37 then forces the drawer 25 to exert sufficient force to force the shoulder 36 to pass the stop 37 so as to allow the displacement of the locking member 14 up to to its locked position. In this locking position, the shoulder 36 is

<Desc / Clms Page number 10>

 while pressing, by its rear face, on the stop 37 which prevents a free return of the drawer 25 in the unlocked position.

 Furthermore, preferably but not strictly necessary, the device 1 also comprises means 40 for adjusting the length of the sheath.

 According to the example illustrated, the adjustment means 40 have a semi-automatic operation and comprise, for this purpose, a slide 41, as more particularly illustrated in FIG. 8, intended to be integral with the end of the sheath of protection 2 while allowing the passage of the control cable 3. The slider 2 can then either be overmolded on the sheath 3, or on the contrary attached to the latter after molding. The slide 41 is intended to move in translation parallel to the extension axis D of the protective sheath 2 inside a bore 42 arranged in the body 10. The slide 41 then moves between a position d 'extension and a retraction position. The adjustment means 40 also preferably comprise a helical spring 43 interposed between the slide 41 and the body 10 in order to control or push the slide 41 into the extended position. Thus, the spring 43 acts in the direction of increasing the length of the sheath 2 in order to minimize the operating clearance of the cable 3.

In order to avoid displacement of the slider 10, during the transmission of a force by the cable 3, the adjustment means 40 finally comprise means for blocking the translation of the slider 41 relative to the body 10.

 According to the illustrated example, the locking means comprise at least one rack 44 arranged on one face of the slide as well as at least one and, according to the illustrated example, several teeth 45 arranged on the drawer 25. The teeth 45 and the rack 44 are then designed so that, in the unlocked position, the movements of the slide are free while in the locked position of the drawer, the teeth 45 cooperate with the rack 44 thus causing a blocking of the movement of the slide relative to the body 10.

 This particularly advantageous arrangement of the invention, consisting in associating the blocking of the length adjustment means with the locking of the fixing of the device according to the invention, makes it possible to obtain an automatic adjustment of the sheath length or of the length

<Desc / Clms Page number 11>

 free of the control cable until the device is fixed to the support 4.

 According to the example described above, during the passage of the means for blocking the translation of the slide 41 from the unlocked state, corresponding to the unlocked position of the drawer, in the locked state, corresponding to the locked position, the relative position of the slide 41 relative to the body 10 does not vary. However, according to an alternative embodiment of the invention, the rack 44 and the teeth 45 could be adapted to induce a displacement in axial translation of the slide 41 when the translation of the slide 41 is blocked. To this end, the axis of the teeth 45 and teeth of rack 44 could be inclined relative to the axis of translation of the slide 41. Depending on the direction of the inclination of the teeth, the movement of the slide, when the translation is blocked, would correspond either to a movement in extension, that is to say a movement in retraction.

 Furthermore, in the context of a preferred application, the device according to the invention is intended to ensure transmission of movements between, on the one hand, the control cable 3 movable in axial translation inside the sheath of protection 2 and, on the other hand, a rotating member 10 in axial rotation about its axis A relative to the support 4.

 Thus, the body 10 is equipped with a lever 117 integral with the body 10 and movable in rotation about an axis A. Preferably but not strictly necessary, the axis of rotation A of the lever is substantially perpendicular to the direction D extension of the sheath 2 and displacement of the control cable 3; thus, the transmission of forces between the control cable 3 and the lever 117 is optimal.

 In accordance with the invention, the lever 117 can be adapted in any suitable manner to the body 10.

 According to the example illustrated, the body 10 comprises an arm 118 at the end of which is arranged a bearing 119 for guiding and receiving the lever 117. The lever 117 then comprises a cylindrical part 120 intended to come to engage in the bore 119 of the body 10. The cylindrical part 120 has a flange 121 which carries means 122 for connection with one end of the cable 3. Opposite the flange 121, the cylindrical part 120 carries two ears 123 intended to allow a

<Desc / Clms Page number 12>

 immobilization in translation of the lever 117 on the body 10 in the bearing 119 in the manner of a bayonet locking system. To this end, the bore 119 has two axial grooves 124, of a shape complementary to that of the ears 23.

 Thus, the mounting of the lever 117 is carried out by presenting the ears 123 facing the axial grooves 24 as is more particularly illustrated in FIG. 2 then by engaging the lever 17 in the bore 19 in the direction of the arrow F5, so as to place the cylindrical part 120 inside the bore 119. Of course, the cylindrical part 120 has an outside diameter substantially equal to the clearance, or less than the inside diameter of the bore 119. Then, the locking of the lever 117 on the body 10 is effected by pivoting in the direction of the arrow F6 of the lever 117 around its axis of rotation '.

The lever 117 is then in a position, relative to the body 10, as illustrated in FIG. 10.

 In this state, the movements in axial translation of the lever 117 are blocked in one direction by the ears 123 and in the opposite direction by the flange 121 which come to bear on the faces of the body 10, at the level of the bearing 119. Furthermore , in this state, the cable 3 can be hooked to the connecting means 122.

 According to the example illustrated, the connecting means 122 comprise a cavity 130 intended to receive a hooking head 132 secured to the cable. Preferably but not strictly necessary, the lever 117 comprises, in the extension of the hooking cavity 130, a groove 133 intended to guide the cable to the cavity 130. The groove 133 also ensures the winding of the cable 3 during movements of the lever 117.

 Furthermore, the lever 117 comprises coupling means with the rotating member 104. According to the example illustrated, the coupling means are produced in the form of an axial bore 135 having a square section. The bore 135 is then intended to receive a male part 36 of complementary shape, fitted at one end of the rotating member 4.

 After assembly of the device, as explained above and installation of the sheath 3 as well as of the cable 2 attached to the lever 117, the transmission device, according to the invention, is implemented in the following manner. An operator comes to place bore 135 on

<Desc / Clms Page number 13>

 the male part 136 of the rotating member to be controlled and then presses the entire device against the support 5. Next, the operator proceeds to fix the body 10 to the support 4 with the fixing means 11, as has been specified above.

 The transmission device 1 according to the invention is then in an operating configuration as illustrated in FIG. 1. Thus, when traction is exerted in the direction of arrow F6, on the cable 3, the latter is transmitted to the lever 117 which drives the rotary member 104 in rotation in the direction of the arrow F7. Furthermore, it should be noted that a rotation of the rotating member 104, in the direction of the arrow F8, is also transmitted via the lever 117 to the cable 3.

 Similarly, in accordance with the invention, the cable 2 can be guided so that the cable 2 works in "push-pull" mode to control a rotation of the lever 17 in both directions.

 According to the example illustrated and described above, the body 10 comprises a bore for receiving the lever 117. However, another assembly could also be carried out. For example, the body 10 could have a pivot on which the lever 117 is engaged. Of course, all other forms of mounting, making it possible to ensure the rotation of the lever 117 relative to the body 10, could be retained.

 Furthermore, the presence of the lever 117 on the body 10 is not necessary for the production of a fixing device according to the invention.

 According to the example described above, the hooking member and the locking member are intended to be arranged jointly in the locking position in the same window of the support 4. However, such an arrangement is not necessary for the realization attachment means according to the invention.

 Thus, FIG. 9 illustrates an exemplary embodiment according to which the hooking member comes to fit the edge 150 of a hooking window fitted 151 in the support 4, while the locking member comes to be placed in a second window 152 also fitted in the support 4, so as to prevent any translation of the device 1 parallel to the plane of the external face of the support 4.

 Of course, all other configurations of the latching member and the locking member as well as the edges

<Desc / Clms Page number 14>

 hooking and locking the support 4 could be considered. Thus, the attachment member could have, for example, a T-shape so as to simultaneously fit two attachment edges of the support 4.

 The invention is not limited to the examples described above and various modifications can be made without departing from its scope.
