Description

Glass fixing and mounting system

motor vehicles.

  The present invention relates to a system for fixing and mounting fixed and mobile windows, motor vehicles in general and in particular

motor cars.

  As is known, the windows of motor vehicles are currently mounted, by interposing elastomeric seals, in seats with retracted edges provided on the bodywork. The two types of glass, fixed and mobile, are generally surrounded along the entire perimeter by a centering and retaining frame which, in the case of fixed glass, is constituted by the aforementioned elastomeric lining and, in the case of mobile glass, consists of a rigid gutter structure which contains sliding

ice, by the interposition of a general garnish-

made of flocked elastomer.

  These known mounting systems have V'incon-

come from a significant discontinuity of the surface

  exposed to wind relative to walking, with

  quence the formation of vortices and a detachment of fluid nets. The windows are indeed set back from the positioning surfaces of the

  uprights and frames that formally support them

  consequent tion of edges and in general of disconti-

  prominent nights also oriented perpendicular-

lie to the direction of travel. This has the effect of

  part of significantly increasing the CX coefficient of penetration

aerodynamic tration, sometimes canceling the amenities-

  sophisticated molding of body shapes, and

on the other hand to harm all the more appreciably if

lence of driving and thus the comfort thereof.

In addition, the aforementioned projecting edges and discontinuities constitute as many negative elements for the effects of the active and passive safety criteria imposed on the shape of the motor vehicle.

  We also know motor cars in the-

which the movable side windows are mounted free, at

know protruding and devoid of peri-

  spherical. However, such a solution does not eliminate the

  disadvantages criticized above because if on one side it

  slightly reduces aerodynamic efficiency due to the fact that the surface discontinuity remains between the upright and the glass, it introduces on the other hand a significant complication of the bearing structure of said glass which must be more robust and, by immediately, cumbersome and expensive.

  The object of the invention is essentially to

  undermining the drawbacks of known mounting systems

mentioned above.

  An important objective of the invention is in particular to provide a system for fixing and mounting the windows, both fixed and movable, so as to ensure a significant improvement in the surface continuity of the bodywork with, consequently, the elimination of swirls. , better aerodynamic efficiency and greater comfort

of driving.

  Another important objective of the invention is to

read an assembly system which, at the same time, ensures

  effective ice guidance and retention.

In particular, the invention aims to achieve a system

  structurally simple, light and suitable for fixing

  rer, in the case of retractable movable glass, the guidance of said glass over the entire trajectory of its movement, thereby ensuring effective retention, also

  in the intermediate opening and / or closing positions

meture.

Another important objective of the invention is to

  read a particularly efficient fixing system

sealing against infiltration of both water and air.

  An additional objective of the invention is to

  Read a fixing and mounting system of a particularly aesthetic quality The above object and objectives as well as others which will be better understood in what follows, are achieved according to the invention by a system characterized essentially by the fact that the glass is attached directly to the outside of

  the fixed or mobile supporting structure, in relation to

  guided and co-planarity with adjacent windows and possible body parts not occupied by said windows and / or interposed therebetween. Fixed windows, for example front and rear, rest externally on the fixed support posts to which they are fixed by

  interposing an adhesive and, by wrapping exterior-

the said amounts extend beyond these

  niers to connect to the side windows. The latter, which may include a fixed part, carry - on their internal face - sliding guides suitable for engaging with corresponding sliding seats secured to

the resistant structure of the door. Elastic toppings

  sealing tomerics are provided between the parts

mutually mobile from said structure-resistant,

inside of the windows, a C-profile trim being available

seated above with a drip tray function, and being in sealing contact at least with the upper contour of the respective movable glass 7 Other characteristics and advantages will appear

clearly in the detailed description which follows, of a

  exemplary embodiment according to the invention, given by way of indication but in no way limiting, with reference to the drawings

annexed, in which -

FIG. 1 represents a partial view in side elevation of a motor car provided with windows according to the invention; 2 shows a partial perspective view of said motor car showing the detail of a movable side window of the retractable type; and

Figures 3 to 6 show cross-sectional views

versale on an enlarged scale along the corresponding lines

  III-III to VI-VI of Figures 1 and 2.

Referring to said figures, a distinction is made between the fixed front window 10, movable front side windows 11 and rear 12 and the lateral upright 13, of the roof 14 of the

  body. The adjacent windows and the body parts

series exposed to view, as in the example shown

felt the uprights 13, are arranged in relation of conti-

guided and mutual co-planarity in the sense that said glass and said parts are all positioned on the same surface following the generatrices of said surface so as to connect to each other without protruding and / or re-entrant continuity solutions, the generatrices

  being only broken along the lines which delimit

  try the contours of separation between the glass and the elements

  fixed body parts and movable windows. So,

for example, Figure 3 shows the continuity of the position-

  ment on the surface between the side windows 11 - 12 and the intermediate upright 13, while FIG. 5 shows the surface continuity between the front window 10, a non-sliding fixed part lla of the side window 11 and said

  side window, and Figure 6 shows the continuity of over-

  face between the side windows and the roof of the roof 14.

  The aforementioned figures also show that said conti-

  surface night is interrupted only by the lines of

  LC contour of fixed windows or fixed parts of the car-

bodywork and movable windows. Surface continuity in the direction specified above is obtained, in accordance with the invention, by fixing directly outside the

  fixed and mobile supporting structure, the corresponding glass

  your fixed and mobile respectively. For this purpose, the ice

  before 10 is fixed, for example and preferably by the in-

terposition of a layer of adhesive SA, to the front uprights 15 of the roof which are consequently inside said glass. Said ice extends to the limit of

the size of the upright so as to be connected to the

non-sliding tie lla side window. Said non-sliding part is in turn fixed, by means of a layer of adhesive SA to the frame 16 of the door P,

  said frame being able to be limited to only two lateral uprights

  or which can also bypass the opening of the window, as in the example shown. Between the frame 16 and the outline of the door opening, delimited by the uprights 15, by the roof of the roof and by

  the floor (not shown) of the body, is interpolated

a first tubular lining 17 made of elastic material

mother fixed on the body and having known function

to serve as an elastic retaining and sealing element

  be the two elements constituted respectively by the door

  body and body. A second lip seal 18 carried by the fixed parts of the roof is also provided.

  to close the opening 19 included between the uprights 13 -

of the pavilion and the corresponding amounts of frame 16 of

the door.

  In correspondence with the upper contour of the doorway, said second lip lining is formed by a portion of lining 18a having a curvature capable of forming a drainer 20 for collecting and draining water from the roof. The free lip of said lining adheres, in forced contact engagement, against the upper contour of the corresponding glass 11 -12 when the

door is closed by substantially forming a pocket.

When the door is open, the lip moves outward, collecting water from the roof and conveying it into the vertical channels formed by the sections

18.

  The fixed part 11a of the side window carries, on the internal face and directly fixed with the aid of an adhesive, a fixed sliding guide 21 with a C profile in which a corresponding movable shoe 22 engages carried by

  mobile glass ll and itself fixed directly to the interior

laughing of said glass by adhesive. Between guide 21 and

  pad 22 is interposed a lining 23 of known type cons-

with a flocked elastomer. On the opposite side, the glass is provided with a movable guide with a C 24 profile too.

fixed on the internal face by adhesive. With said guide coo-

  father a fixed pad 25 secured to the frame 16, between said guide and said pad being interposed a lining 23a of the type specified above. The movable shoe 22 and the guide

mobile 24 are preferably parallel to each other to react

read the ice retention along the entire trajectory

  corresponding to the closing and opening translation

ture.

For the rear side windows, the same arrangement with combined sliding shoe and guide is provided, but naturally, although advantageous, said arrangement is not limiting and it can be provided on each window, two mobile guides in C, or two more mobile skates cooperating

with a fixed C guide.

  We can clearly see in the figures that the

glass tower extends beyond the guides, or pads, to connect - by the surface continuity specified above - to the glass or to the upright part

  and the adjacent pavilion. In the example shown, the

  as long as 13 is left in view and the outline of the side windows is connected to the surface of said uprights. However, it is

  also planned to move the surface of the upright and pro-

follow the contour of the windows 11 and 12 until making the

  said windows adjacent and superimposed on said uprights.

  In this case, the entire lateral surface of the pavilion is surrounded by said windows with an effect of a quality

particular aesthetics.

Figure 4 shows the waterproofing arrangement

filters in correspondence of the escape passage slot

motive glass inside the door P, said sealing being here performed in a traditional manner by a pair of opposite lip linings, respectively internal 26 and external 27. Said linings are made of elastomeric material and their surface in contact with the

ice is in a flocked form to facilitate coating

smoothing of said ice.

Naturally, observing the principle of the invention

  tion, the execution details can be varied widely

and embodiments compared to those that are de-

written and represented above by way of nonlimiting example, without departing from the framework and the spirit of

said invention.
