Description

Window regulator with cursor lock and procedure corresponding assembly.

The invention generally relates to power windows and, more especially, the power windows with cable.

The Citroën XSARA has a window regulator mounted classic. Its assembly includes a stage of fixing a gearmotor to a window regulator structure on the premises from the window lift supplier. The window regulator that is assembled in the door therefore includes the mechanism part and the part of the gearmotor. A cursor drag cable is inserted into a Slot of a motor reducer drum. The cursor is then placed in a mounting position of the moon. Next, the Window lift to a door panel. Then, a moon is fixed to the cursor. The gearmotor ensures the braking of the cursor (s) during the fixation of the moon.

US 4 970 911 describes a window regulator device that has traction cables for the rise and fall of the moon. The window regulator includes a part motorized drag featuring a section output shaft regular polygonal, with n sides. The window regulator includes a part of cable winding, especially featuring a drum of curl The winding drum has a hole of reception of the output tree. This hole has bulges angular in a multiple number of the number n of sides.

For mounting the Peugeot 307, a Window regulator on a previous door. Then you assemble a moon to a window lift cursor. An area is then delimited wet and a dry area inside the door. The part of Window regulator already mounted on the door is located in a wet area. A engine, not waterproof and presenting a multiplexed command, is mounted later on the window lift in dry area. Other obligations of manufacturing also encourage builders to mount the engine on the window regulator after the assembly of the window regulator at the door, and after the assembly of the moon in the window regulator.

Before fixing a motor organ to the window regulator structure and, more specifically, before coupling of the motor to a drag drum, fixing the moon to the cursor is difficult, especially if the window lift is already assembled at the door. Also, the cursor position cannot stay fixed during the window lift transport until the door or vehicle, unless additional elements are added for block rotation: additional cost of parts and handling additional. It is especially known the placement of tweezers that clamp the drum and the lid. Said clamp does not prevent the rotation of the drum, but ensures only the hold of the drum in the cover, then removed to mount the engine. This system It is used for VW Golf type A4; see for example DE 33 25 837 A and US 6 094 868 A.

Therefore, there is a need for a window regulator that solves one or more of these inconveniences. By the invention proposes a window regulator that includes a cursor of moon, a cable attached to the moon cursor, a pulley housing, a pulley that drags the cable, presenting the pulley means of coupling of a motor organ and mounting locked in rotation in the housing in the absence of motor organ coupled to the pulley.

According to one variant, the pulley is locked in the housing due to the effect of the cable tension.

According to another variant, the pulley is mounted on cantilever in the housing, in the absence of coupled motor organ to the pulley, due to the effect of the cable tension.

According to another variant, the pulley is a drum of cable winding

According to another variant, a projection is provided in a piece between the pulley or the housing; a notch of block adapted to the projection is provided in the other piece between the pulley or the housing.

It can also be expected that the window lift also include a guide rail, and that the cursor be held in a predetermined position to the rail by the pulley locked in rotation.

The object of the invention is also a window assembly procedure, which includes the stages of supply of a cable pulley that has means of coupling of the motor organ and supply of a housing of pulley, of a cursor and of a cable, of union of the cable to the pulley of way to drag the cable, fixing the cable to the cursor, placement and blocking of the pulley rotation in the accommodation.

According to a variant, the procedure includes also a stage of application of a tension to the cable, so as to keep the cantilever drum in the housing.

According to another variant, the procedure includes, after the previous stages, coupling stages of a pulley motor organ, drum unlocking.

According to another variant, the procedure includes also a stage of supply of a tree in the housing, and the pulley unlocking stage includes pulley placement and The motor organ in the tree.

According to another variant, the cursor remains at proximity of its upper position.

Other features and advantages of the invention will appear with the reading of the following description of modes of embodiment of the invention, carried out by way of example and with Reference to the attached drawings, which show:

The invention proposes a position lock of a moon cursor in the absence of a motor organ. By example, this lock is activated to keep the cursor in position for fixing the moon to the cursor. A cable couples the cursor to a pulley The pulley is locked in rotation in a housing in the absence of the motor organ.

Figure 1 presents a side view of a window regulator according to the invention, before the assembly of a moon and a motor organ The window lift 1 includes for example two rails of guided parallel 2. A moon cursor 3 slides on each guide rail 2. A drag cable 4 is fixed to the cursors 3. The cable is deflected by a 5 forwarding located in the ends of the rails 2. The cable passes through a pulley made in winding drum shape 6 by which it is dragged. He winding drum is placed in a housing 7, made for example on a protrusion of rail 2. The drum it presents coupling means 8 of a motor organ.

Figure 2 depicts a drum of cable winding 6 of a first embodiment. This Drum 6 performs the work of cable drag pulley. Saying drum 6 therefore has a groove 10 into which it is inserted cable 4. This slot can be made helical to allow wind the cable in several turns of drum. The drum can like this ensure proper cable routing and drag. Cable 4 is also capable of exerting an effort in the axial direction of the drum 6. Drum 6 also has two terminals 11 and 12 which they form projections radially. Although the described embodiment later it presents two terminals, a terminal is of course enough. The drum 6 also has ribs of coupling of a motor organ. The drum also features a guide bearing not shown.

Figure 3 depicts a drum housing 7 of the first embodiment. Accommodation 7 presents a hollow delimited by a bottom 13 and a wall substantially cylindrical 14. The hole has adequate dimensions to receive the drum 7. The housing has on its periphery some notches 16 and 17. Of course, a number other than notches For example, a higher number of notches can be provided to the number of terminals, in order to place the drum in Different discrete positions. Notches 16 and 17 can receive terminals 11 and 12 respectively. Terminals 11 and 12 are flanged laterally by notches 16 and 17 when the drum is in locked position. The terminals and the notches  thus allow selectively blocking the rotation of the drum or of the Pulley, if applicable.

The housing 7 also has a slot 15 provided on the cylindrical wall. This slot 15 forms a step for terminals 11 and 12. The drum can thus rotate freely in the accommodation in functional drag position. Accommodation optionally presents a guide tree 18. This tree it is arranged approximately in the center of the bottom 13. The tree 18 eventually allows to guide the drum bearing, when the drum is in functional drag position in the window regulator The housing 7 has a slot 19. This slot allows the passage or guidance of the cable 4.

Figure 4 represents a perspective view of a cut of a housing and a drum arranged in the housing in locked position. Terminal 12 is inserted into the notch 16. The rotation of the drum around its axis in the accommodation is thus blocked. Cursor 3, attached to the drum by middle of the cable 4, is thus locked in a certain position. For example, a vertical effort can be applied to cursor 3 during the fixation of a moon, not represented, without displacing said cursor. The cursor position is also flanged during the window lift transport. Series can be obtained like this of windows that have a default cursor position, even after a transport stage. Rear assembly of the moon in the cursor is thus facilitated. In this way, it is not it is necessary to attach the drum 6 to a motor member before fixing the Moon to cursor. Of course, drum rotation can unlock, as will be described later.

The terminal is kept in the notch by Any suitable means. It can thus provide that the cable or a Spring exert adequate effort on the drum. In the example, the cable tension can be used to exert an effort which separates the drum relative to the bottom 13, as will be detailed more ahead.

Figure 5 represents a perspective view and in a cut of the housing and the drum in functional position. Terminals 11 and 12 are kept out of notches 16 and 17. The terminals are then held in slot 15. The drum can then turn freely in the housing, since the terminals leave of flanging the rotation. The terminals can then slide through slot 15. The drum is preferably arranged in the functional position of figure 5 after transport or moon assembly. In the example, just keep a force in the right drum to keep the terminals out of the notches. For example, it can be foreseen that once the drum or the Functional motor organ, the terminals are kept out of the notches. For example, it can be provided that a motor organ is fix on threads 20 and apply an effort to the drum along the axis of the latter towards the bottom 13.

With the drum in this functional position, the Drum bearing 21 is guided in rotation by means of shaft 18. An operating set is preferably arranged between the bottom 13 and the drum.

Although in the described embodiment it is use a positive rotating drum lock, you can also propose other embodiments in the framework of the invention. You can also consider blocking the rotation of the drum by friction or by a drum overhang in the accommodation.

Figure 6 therefore represents a drum 6 locked in rotation in a housing 7. Drum 6 is cantilevered against a guide shaft 18. Cable 4 is wound on the drum 6. The cable is tensioned so as to exert a cantilever effort on the drum. The arrow represents a example of effort applicable to the drum. This effort maintains the pulley in pivoted position, with two edges of an inner hole of drum in contact with the shaft 18. The friction exerted between the drum and the housing tree allows both to maintain the drum in the housing and block the rotation of the drum. This cantilever position can be obtained by arranging two forwards placed substantially on the plane of the cantilever drum.

To unlock the drum rotation and that of this mode is operational, it is possible to insert a cylindrical tie between the drum and the cylindrical shaft, as shown in the figure 7.

Figure 8 represents a variant of the window lift of figures 1 to 5, in which the cable 4 exerts a effort, keeping the drum in a locked position. Some cable forwards 22 and 23 are placed so as to exert a effort that separates the drum in relation to the bottom of the housing. For example, forwards are placed in an outdated plane with relation to the plane of notches 16 and 17, in the direction of drum separation in relation to the bottom of the housing. From this mode, while the drum is not held in functional position, the cable keeps said drum in notches 16 and 17.

The invention also affects a process. window assembly assembly. Thus, the supply of a cable pulley that includes means for coupling an organ engine. In addition, a pulley housing, a cursor and a cable.

The cable is connected to the pulley way to drag the cable, the cable is fixed to the cursor, placed the pulley and its rotation in the housing is blocked.

The cable can be tensioned in order to maintain the cantilever drum in the housing, as described previously.

Also, you can later attach a Motor organ to the pulley and unlock the drum.

Likewise, the provision of a tree in the housing, so as to unlock the pulley by placing the pulley and the motor organ in the tree. It can be done like this, during a stage, the assembly of a motor organ in the window regulator and Unlocking the pulley. In this way, it facilitates and reduces the fabrication process.

It can also be expected that the blocking of the pulley is made so that the cursor stays in close proximity of the upper position of its path. On the one hand, an operator you can mount the moon on the cursor, without having to duck in excess and, on the other hand, assembly is facilitated if it is already assembled a door panel to the window regulator before mounting the Moon.

Of course, the present invention is not limited. to the examples and embodiments described and represented, but it can have numerous variants accessible to the expert in the matter. Therefore, although a previously described winding drum combined with a cable, you can also propose, within the framework of the invention, the use of a wheel toothed that acts on a Bowden cable, giving the wheel a rotating locking device.
