ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
This invention relates to a simplified window winder device applicable for raising or lowering the window pane in the doors of automobile vehicles.
2. Prior Art
Window winder devices are known that include several items, such as the guide slide, manual or electric drive, spirals, nozzles, tension adjuster springs, etc, of the Bowden system, cable direction changing units, units for securing the device to the vehicle, etc. In these known window winder devices, the components described are usually incorporated during the assembly of the devices into the door of the vehicle.
All this is a great disadvantage as it means an additional cost, which is substantial in the economic calculation of the device, not only from the point of view of storage and transport but also in other stages of its life.
OBJECT OF THE INVENTION
One object of this invention is to provide a window winder device that totally integrates the cable direction changing items and also the items for securing the system to the rest of the vehicle in one single part.
Another object of the invention is to provide a window winder device that includes the drive motor in such a way that it enables the elimination of the different components of the Bowden system, such as spirals, nozzles and tension adjuster springs, all of which results in the greater economy of the system.
Another object of the invention is to provide a window winder device that, by integrating different items into the assembly itself, achieves a substantial reduction in costs, both in storage and transport and in other stages of the life of the device, manufacture, assembly or repair.
SUMMARY OF THE INVENTION
In order to achieve these objectives of the invention, the simplified window winder device is composed of three fundamental parts, which are:
A plastic rail, with the cable direction changing systems, the supports between the system and the rest of the vehicle and a special portion to suitably receive the motor for the system, all of which is carried out in one single constituent part.
A slide that acts as the union between the window winder device and the window pane in the door of the vehicle.
A motor casing that, while connected to the system motor itself, is also used for positioning the said motor in the rail and for tightening this system, when it is situated on the special portion of the rail.
Apart from this, the window winder device has a cable suitably arranged in the rail for the movement of the window pane secured and moved by the slide.
The rail is an elongated longitudinal item at whose ends are situated the necessary devices in order to procure the change of direction of the cable which has to make the window pane holder slide circulate or move along it. Besides this, the rail itself contains the items for securing the rail to the door or to the rest of the vehicle, as well as a special projecting portion for housing the motor.
This special portion has a hole through it in the portion closest to its end when starting from the rail itself and two concentric curved cut-outs or slots of different diameters housed distinctly in relation to the position of the said hole, which for all effects acts as the pivotal centre in relation to the two slots.
The cut-out with the larger diameter is provided with a toothed or serrated area in its interior which, as will be explained later, is used in order to maintain the angular position desired of the motor during the assembly of the window winder device.
The electric motor to drive the slide by means of the corresponding cable is connected, in accordance with the invention, to a special casing. This casing, made of plastic material, is joined to the motor by means of two bolts that each pass through holes in the body of the said plastic casing.
In the same way, the casing has another three holes through which the corresponding two bolts pass through that will circulate along the larger cut-out in the projection from the rail and a third which, by means of another screw, will occupy the position of the hole in the projection from the rail closest to the said rail, thus performing the functions of the pivotal centre point.
In the centre of the plastic casing, approximately, another hole is provided, together with its corresponding bolt, which coincides in position with the hole in the smaller cut-out in the special projection from the rail.
At the opposite end of the pivotal centre of the plastic casing and between the two bolts in the casing that move in the larger cut-out, a toothed plastic spring is provided that forms a single unit with the casing, and which makes contact with the toothed interior that the larger cut-out on the rail is equipped with.
Once the motor has been fixed to this plastic casing, the motor and plastic casing assembly is presented over the projection from the rail in such a way that the larger cut-out of this projection coincides with the corresponding bolts, the smaller cut-out coincides with the central bolt in the casing and the end bolt coincides with the circular hole in the projection from the rail.
At the same time, the correspondence between the toothed part of the projection in the larger cut-out is carried out appropriately during assembly, so that once the angular position desired has been achieved by turning the casing suitably on the cut-outs, the said correspondence between the toothed areas allows the said angular position to be maintained while the tightening of the bolts corresponding to the projection from the rail is carried out, so as to completely fix the position of the motor and casing on
