Description

CRYSTAL DRAW PLATE IN VEFFLCULLE ELEVALUNAS

DESCRIPTION

The invention relates to a drag plate used in windows of motor vehicles, whose purpose is to carry out the union thereof with the moon of the door.

Within this technical field, several devices are known for the execution of the union of the glass with the window carriage. One of these systems uses plastic couplings prepared for this purpose, which are housed in holes arranged in the glass, with special screws that make the permanent glass-carriage joint.

Generally, and apart from the car itself and the moon, this known system requires the contest of two plastic couplings and two special screws. Also, its assembly is certainly laborious, due precisely to the existence of the cited pieces.

It is an object of the invention, a drag plate that eliminates auxiliary components in its application to the moon.

It is another object of the invention, a drag plate that substantially reduces assembly operations.

For the implementation of these objectives, the invention claims a drag plate as the only component of the assembly for the translation of the door's moon.

This drag plate consists of a substantially flat piece made of plastic preferably, of one of whose faces protrudes at least one perpendicular projection responsible for being housed in a hole in the glass, a hole that, as traditionally, is made in proximity to the edge thereof. On the same face where this protrusion is born, a raised pin also stands out in the direction of the protrusion and arranged in its vicinity.

The projection logically forms a unique whole with the plate and has a circular middle cross section. In the starting from the face of the plate, two holes or separations are established between the plate and the projection which are located in diametrically opposite positions, said holes being of a circular sector and totally crossing the plate.

The pin located in proximity as commented, is positioned with its opening perpendicular to the center line of the two holes of the beginning of the projection.

This projection has a particular geometry, based on a stem and an outstanding head of said stem. This stem is of general circular component in its cross-section and is provided with a recess along its entire length, this recess being circular sector.

The head of the projection is oversized with respect to the stem and shows a conical shape with the same general center as the said stem, providing on its lower face two seating areas that correspond vertically with the openings of the plate base described above. .

The seating area of this head that is on the side of the plate pin is located at a height greater than that of said pin and the one on the other side is made at the same height as that of the pin.

The groove in the base of the plate on the side of the pin, also constitutes a pocket-like hollow in the base of the plate, which is located on the upper side thereof.

On the other hand, the plate has at least one additional piece which is injected at the same time as the plate itself and is attached to it by a small protruding plastic strip on one side that is provided with flexibility to allow movements of the additional piece.

The plastic strip is born from a side not far from the position of the projection of the plate so that when flexing, it leads to the additional piece in the direction of said projection.

The additional piece is constituted by a circular disc of closing of the plastic strip and an elevation that protrudes from this disc, elevation that in position of extended plastic strip rises in the opposite direction to that of the protrusion of the base of the plate referred to above .

The elevation of the disc that constitutes the additional piece shows a cross section in the form of a circular sector similar to that of the emptying of the projection of the base plate. At a certain height this elevation has a horizontal projection that projects towards the circular outside of the piece, this height coinciding exactly with the height at which the pocket of the base of the drag plate is made, also already mentioned previously. The total height of the elevation is equal to the height of the stem of the projection of the base of the plate where the emptying is practiced.

The operation of this drag plate according to the invention is carried out as follows.

The hole of the crystal is positioned on the head of the projection and the edge of the crystal is introduced below the pin. The glass is pressed so that it exceeds the head of the projection thus leaving the glass controlled by the lower seating area of the head of the projection of the base of the plate and by the pin itself, the glass resting superficially against the surface of the plate .

Next, and by the opposite side of the plate, the additional piece is introduced by flexing the plastic strip, so that the elevation of this piece is received in the recess provided by the cavity of the projection stem. In this introduction, the free end of the lift contacts the highest seating area of the head of the projection, the elevation of the elevation is housed in the pocket of the base of the plate and the disk is located outside.

In addition, the cross section of the elevation is perfectly adjusted inside the cavity of the projection stem constituting a circular cross-section between the two equal to the hole section of the glass.

In this way, it is absolutely certain that the glass can be removed from its seat and connected to the drag plate.

In order to disassemble this connection, any device is used, for example a screwdriver, which is inserted into the space between the carriage and the disk of the additional part, so that the lever allows the assembly to be deciphered.

Once this operation has been carried out, the glass is lifted and pressed out to release the assembly.

The drag plate of the invention can be provided with double projections, pins and additional parts, which is mentioned here for the appropriate purposes.

All these and other details of the invention can be seen more concretely in the attached sheet of drawings, which represents the following:

- Figure I ^a , is a plant of a drag plate according to the invention.

- Figure 2 ^a , is the result of section II practiced in fig. I ^a .

- Figure 3 ^a , is the result of section Ü-II made in fig. I ^a . - Figure 4 ^a shows the section iπ-HI practiced in fig. 3 ^a .

- Figure 5 ^a represents a perspective of the additional piece.

- Figure 6 ^a , is a section showing the final assembly of the glass on the drag plate.

According to fig. I ^a , we appreciate one of the faces of the plate of the drag plate (1) in which the projections (2) with the diametrically opposed and arc-shaped grooves (15, 7) are appreciated, in the protruding pins ( 3) open in the direction of the projection (2). Both protruding elements (2) and pins (3) are represented on this face of the drag plate, protruding from it.

There are also two strips (13) of flexible plastic topped by additional pieces (9, 10), which protrude towards the unseen face of this figure. I ^a .

The section of fig. 2 ^a allows us to appreciate the corresponding positions of the projections (2) and the pins (3) arranged on the plate. This plate is made of injected plastic with exterior dimensions, thickness, reinforcements ... etc., perfectly studied to offer adequate resistance to the requirements to which it is subjected.

From fig. 3 ^a , we deduce the arrangement of the part of the plate on which the projection (3) and the pin (2) are made. Thus, we accurately appreciate the projection (2) with the stem (19) and the head (20), as well as the indentations (15, 7) on both sides of the stem.

In the slit (7) the pocket (14) can also be seen, and in the stem, of circular section, we notice the cavity (8) that is shown in fig. 4 ^a .

In the head (20) of the projection (3), we highlight the lower seating area (4) for control and support of the glass, as well as the other seating area (5), higher than the previous one, on which it rests and the piece is controlled additional.

With respect to the pin (3), highlight the entrance it provides for the glass, the wall (6) being at the same height as the seating area (4) of the head (20) of the projection (2).

With respect to fig. 5 ^a , we highlight the additional piece with the base disk (9) and the elevation (10) with its circular sector section corresponding to that of the cavity (8) of the stem (19) of the projection (3) and with the protrusion (11) to accommodate in the pocket (14) of the drag plate.

According to fig. 6 ^a , we notice how the final assembly is articulated with the glass (16) controlled between the seating area (4) of the projection (2) and the recess (6) that the pin (3) provides.

The hole (17) of the glass (16) is completely occupied by the meeting of the stem (19) and the elevation (10); the pocket (14) occupied by the projection (11) of the elevation (10); the elevation (10) controlled by the seating area (5) of the projection (2) and the disc (9) of the elevation (10) that closes the assembly on the opposite side of the plate (1).

This assembly is perfectly stable and secure, controlling perfectly the connection with the only contest of the piece that constitutes the drag car.

To carry out the disassembly, the action is carried out according to the arrow (18) through which the additional piece (9, 10) is deciphered, the glass is removed, the glass is lifted and pressed out to release its housing.
