Window winder operated by unified kinematic chain

Abstract: A window winder operated by a unified kinematic chain, in which the movement of the kinematic chain is carried out by means of a rotating member operated either manually (8,10) or electrically (9), with the chain being common to both, of either the sealed (closed) or open type, based on a cable, a toothed belt, chain, worm-screw - rack ... etc. The operating or drive system is interchangeable, and can be adapted to one system or the other, without having to modify any details of the vehicle door or of the said chain.

Description: This invention relates to a window winder or regulator operated by a unified kinematic chain, applicable to the construction of window winders for vehicles in general. As far as is known in the field of window winders, manually operated units are known and also others which are electrically operated, in which kinematic chains suitable for each kind of drive are used, with these chains being different from each other. This type of conventional manufacture means that, according to the type of drive, one or the other kinematic chain must be used, which, without any doubt, causes a bothersome inconvenience. Patent DE.A. 1 630 609 describes a window winder having the features of the preamble of claim 1 and being operated by a unified kinematic chain with a transmission chain and a drive system for the unit, which has a drive pinion which may be driven by a winding handle or a motor It is an object of the invention to provide a window winder operated by a kinematic chain, both manually and electrically, in which the said chain is common, independently of whatever its drive might be, and, moreover, that the said drives are interchangeable with each other, so that one system can be adapted to the other without any need for modification whatsoever, neither on the vehicle door nor in the said chain. The unfied kinematic chain, which can be applied to single or double track or rail window winders, can be of any type, provided that the movement in the unit is carried out by means of a rotatable element, such as a drum, a crown wheel, a toothed pulley, etc., with this being the common connection element for both drive systems. When the drive or operation is electrical, it will be composed of a motor-reducer, with or without a torque compensator at its power intake, and when the drive is manual, the arrangement of an internal parallel shaft reducsystem is necessary, as well as a braking system, which might or might not have a torque compensator, according to what is convenient, on its power intake which must be identical to that of the electrical system so that the two can be interchangeable. Fixing or securing the system, both manual and electrical, must be identical in both cases so as to perfectly ensure their interchangeability. In this way, in the design of vehicle bodywork, and more specifically as regards the doors of the vehicle, a considerable degree of simplification can be achieved by being able to have the opportunity to standardize the face or side of the door destined for the drive unit from the ergonomic point of view for the manual drive, thus allowing the implantation of both replaceable or interchangeable systems. From the construction or manufacturing point of view, the maximum of simplicity can be achieved, given that a large number of standard components can be used for either of the applications. All of this leads to a considerable cheapening of the product, a high degree of flexibility in assembly lines, a reduction in the investment required and, finally, an increase in the quality of the product. At the same time, and given versatility of the system, simplification can be obtained, not only in the assembly phase but also during its use and replacement, in such a way that an extremely interesting logistics system is establish, in view of the reduction in the amount of references that can be reached. Figure 1 is a general view that includes the window winder elements according to the invention. Figure 2 shows the electrical drive by means of a motor-reducer. Figure 3 represents the manual drive with a reduction and compensation system. Figure 4 shows the support which is common to both drive systems in double track window winders. Figure 5 allows the window winder to be observed, operated by a unified kinematic chain, with electrical drive and a double track. Figure 6 shows a double track window winder with a unified kinematic chain and manual drive. Figure 7 presents a unified kinematic chain with a single track window winder, which can be adapted for the electrical drive, in accordance with Figure 2, or the manual drive, as shown in Figure 3. Figure 8 shows a single track window winder with a unified kinematic chain, adapted for the manual drive system, as shown in Figure 3. Looking now at Figure 1, we can appreciate the synthesis of the invention, with a manual drive (8, 10) or an electrical drive (9) to be fitted onto its seating or support, inside which a rotatable member (1) is provided, depending on the option desired. The whole assembly can be of the single track type, with the wire or conductor (2), the pulleys (4) for the said wire, as well as the window glass drive element (3), which is not shown. This assembly can, in the same way, be established as a double track unit with the wire or conductor (7), the end pulleys (5) and the two drive elements (6,6'). Turning next to Figure 2, we can observe a unit which is electrically operated by means of a motor-reducer (9) connected with the cable drum crown wheel (18), while Figure 3 shows a manually operated unit (8) which includes a reduction system based on a pinion (13) and a crown wheel (14). Both units are capable of being housed on the common support (22) or seating shown in Figure 4, where it is possible to appreciate the casing (16) of the cable drum, as well as the drill hole (15) for the outlet (takeoff) of the manual drive and the guide outlets (17) for the flexible wires or conductors. This support (22) is applicable to double track window winders. One application of the two techniques can be seen in Figure 5, according to which the assembly shown in Figure 2, together with the electric motor (9) and the guide outlets (17) for the flexible wires or conductors (7,7'), has been placed on the support (22). These two flexible wires are directed towards the ends (5,5') of two strips or profiles (11,11') in which the drive elements (6,6') for the window glass move. Similar conditions are expounded in Figure 6, in which the manual unit (8,10) can be seen housed on the support (22), with the recess (16) for the drum casing. When the window winder or regulator is of the single track type, the solution shown in Figure 7 can be appreciated. Here, the seating part for the drive in question is shown, with the cable drum casing (16) and the drill hole (21) outlet for the shaft of the manual drive, as well as the two outlets (13) for the cable (2), the strip or guide (12) and the drive element (3). In this arrangement, either the manual drive device or the electrical drive device can be fitted. Figure 8 shows the single track window winder operated by a unified kinematic chain, in which the manual drive system (10) has been arranged, while also appreciating the winder handle (10), the cable drum casing (16) and the position (20) that represents the brake retainer.
