Abstract

The patent deals with the fact that in cable (23) type window winders, this cable is not subject to alter­nating flexures. The braking chamber is placed in the opposite direction to conventional ones and inserted in­side the casing of the device (A), which makes the assembly considerably reduced in width and does not show any bulging or swelling towards the inside of the vehicle.

Description

  • At present, vehicle manufacturers impose certain de­mands on manually driven window winders; when the winding handle is in the forward horizontal position and is turned upwards, the window glass should rise.
  • In traditional devices with direct action on the cable drum, this implies the fact that the cable that makes up the kinematic chain enters the reel in opposite flexure to that which it takes at the track outlets. On the other hand, so that the winding torque is not very high, it is necessary for the radius of the cable reel or winding drum to be very small. Like this, both circumstances cause the life of the cable to be relatively short in relation to the life demands currently imposed.
  • Thinking about the need and convenience, in cable-­type window winders, of the cable not being submitted to alternating flexures, this patent provides greater life than with traditional systems and also, by having a redu­cer, it achieves a reduction in the operating torque.
  • One object of the patent is, therefore, the fact that the flexure of the cable is always carried out in the same direction.
  • Another object of the patent is the fact that the braking chamber is built into the casing and in the oppo­site position to that of conventional devices and systems.
  • In accordance with the patent, a mechanism is pro­vided made up of a casing, preferably obtained by injec­tion of reinforced fibre glass thermoplastic resin, from which the following are obtained directly: a shaft on which the winding drum or reel has to turn; the cylin­drical braking chamber of the system in which the brake spring and the end of the operating shaft are housed; the cable outlets, top and bottom, which between them form an angle.
  • The two angles between them form the most appropriate angle through which the cable conductor guides have to slide, in a tension regulation system for the cable which is adop­ted, which is oscillating and of fixed or automatic regula­tion.
  • A pinion, also obtained by injection, the same as the casing, has a cylindrical sector equipped with a rear ope­ning, which in its iterior receives a finger of the opera­ting shaft. This finger is a projection of a boss of the shaft itself, so that with suitable annular play, it allows the pinion to be moved simultaneously with a brake spring (4). The said finger has recesses into which the brake springs are hooked, by which the action of transmitting tur­ning to the pinion is carried out directly between the ed­ges of the shaft boss and those of the cylindrical sector of the pinion, without there being any intermediate pressu­re on the hooks and, therefore, without any deformation of these edges. With this, total constancy is achieved in the dead annular play between both and therefore free turning of the handle.
  • If the shaft is not operated, and an attempt is made to lower the window glass, by the cable acting on the win­ding drum or reel, the latter would cause the pinion to turn, and therefore by the cylindrical sector of the pi­nion coming to rest on the lug or hook of the brake spring, it would prevent it from turning by braking the system, braking which is much more effective than in the conventio­ nal direct system, due to the relation that exists between the reel and the pinion.
  • The brake spring is perfectly centred, on one side by an inner edge of the pinion itself which forms an incli­ned plane in relation to its own shaft and on the other si­de by a washer placed over the shaft and equipped with a projection or boss which becomes housed in the cylindrical sector of the pinion. This centering arrangement produces the optimum braking condition of the brake-spring.
  • The winding drum or reel assembly can be made up of one single part or of two, made separately, fitted toge­ther by one clipping over the other. The toothing of the winding drum is inclined-straight, the same as that of the pinion, in order to provide smoothness of movements.
  • The above-mentioned assembly is closed by a meta­llic cover, obtained, from a punched and cut steel sheet, which has one outlet collar or hole for the operation shaft and another for the shaft of the winding drum or reel.
  • The cover is fastened to the said casing by cram­ping the lugs around its edges into the corresponding notches around the casing.
  • The metallic cover has a perfectly flat surface and is equipped with drill holes so that by means of these it can be fastened directly to the vehicle door. The corres­ponding nuts can be welded or inserted into these drill holes. An additional welded support could also be arran­ged in its turn, if it should be necessary to separate it.
  • All these and other details can be seen more clear­ly on the sheets of drawings which are attached, in which the following are shown:
    • Figure 1 shows a general view of a conventional devi­ce with direct action on the cable drum.
    • Figure 2 shows the performance of the patent, in a general view.
    • Figure 3 is an inside view of the casing.
    • Figure 4 is a cross-section view of the mechanism of the patent.
    • Figure 5 is a general perspective of the assembly of the parts, in accordance with the patent.
  • In accordance with the drawings, we would firstly like to point out that in figure 1, a system of direct ac­tion on the cable drum is shown, in which a cable (23) is operated by a drum (25) and a winding handle (24), so that the cable acts on a part (31) which raises or lowers an incorporated window glass by means of a guide or track (26). It can be seen how the cable enters into the drum as a result of the (28) which is developed at the track outlet, which undoubtedly means an alternating flexure of the cable (23).
  • In the same way, the patent foresees a solution, which is represented in fig. 2, in which the cable (23) enters into the winding drum (2) in a way not opposed to the direction generated according to (28) at the track outlet (26).
  • In fig. 1, the handle (24) is shown, together with its turning direction (27) and the direction according to which the cable (23) enters the drum (25). Thanks to these movements, the casing (31) which is connected to the window glass moves with it along the track (26).
  • According to fig. 2, the patent has an entry direc­tion (30) to the winding drum or reel (2), which is, on tur­ning the handle (24) in direction (27) over the pinion (9), in the same direction as shown by component (28).
  • To carry out this innovation, the patent develops the casing shown in figs. 3 and 4, shown by position (A), on which the following are developed: the shaft (1) where the winding drum (2) has to turn; the cylindrical chamber (3) and the support (6). The casing (A) receives the winding drum (2) operated by cable at its periphery, and this drum (2) is connected to the pinion (9), which is assembled on a shaft (5) operated by the winding handle (24), not shown here.
  • Also in relation to fig. 5, we would like to point out the situation of the pinion (9) and the shaft (5) which appear in fig. 4. The pinion (9) has a rear section on the side toward the casing (A), or a cylindrical sector on which the opening (22) with walls or edges (21) can be seen. The hollow in the pinion (9) receives the shaft (5), which has a boss that is raised by the cog (10), equipped in its turn with notches (13).
  • The brake spring (4) is housed on the cylindrical sector of the pinion (9) and the finger (10) of the shaft (5) is received in the opening (22). The finger (10) has annular play which allows the pinion (9) to be moved and, in its turn, the brake spring (4) also to be moved.
  • If trying to operate the winding drum (2) by any other way than the winding handle, for example by forcing the window glass, the winding drum (2) would make the pi­nion (9) turn, and this, by resting its cylindrical sector on the hooks of the brake spring (4), would prevent it from turning, thus achieving braking.
  • The brake spring (4) is suitably centred on the sec­tor of the pinion and on the finger (10) of the shaft (5), by means of its lateral support on the inside edge (11) of the pinion (9), which forms an inclined plane, and, at the other end, thanks to the washer (12), which is moved by its boss (20) housed in the sector of the pinion (9).
  • As was mentioned, the shaft boss (5) which has the finger (10) is equipped with side notches (13). The hooks of the brake spring (4) become housed in these notches (13), so that the action of transmitting turning of the shaft (5) to the pinion (9) is carried out directly bet­ween the edges of the shaft (5) boss and the edges (21) of the opening (22) of the cylindrical sector of the pi­nion (9). All this, without any intermediate pressure on the hooks and consequently without any deformation of the edges, in order to achieve a total constant in the dead annular play between both and free turning of the smallest winding handle.
  • The assembly is closed by the cover (14), which has the collars (15) and (16) for the shaft (5) and the winding drum shaft (1). It is also equipped with holes (18) for fastening, as well as lugs (17) which are recei­ved in the notches (19) in the casing (A).
