FR2629773A1 - MOLDING FOR PASSING THE GLASS OF THE DOOR OF A MOTOR VEHICLE - Google Patents

Abstract

A molding comprising a channel for the passage of the window glass of an automobile has a part having a U-shaped cross section 18 and a part having an L-shaped cross section, which cooperate to form a mounting channel 20 and a window passage channel 22. A tubular biasing and sealing element 28 is arranged in the window passage channel to urge the edge of the window against an opposite branch of this channel.

Description

1.

  The present invention relates to windows of

  tomobile and more particularly, a molding comprising a channel for passing the glass to seal the glass

  window moving from a car door.

  A common feature of automotive doors

  bile is a glass window that can be raised and lowered.

  As is conventional, the glass follows a passage channel

  glass age, which generally extends vertically

  cal, defined by a channel-shaped molding inside

  of the door frame and the upper edge of the glass

  pledge in a branch, generally extending in the horizontal direction, of the channel. The canal is normally covered

  of a flocking material or other material with a low coefficient

  cient of friction, which allows the sliding of the

  glass pane. The channel also protects the glass

  damage due to vibration and makes it waterproof

the edges of the glass.

  In the most common types of mobile windows

  for cars, the edges of the window are centered in the lateral and upper branches of the channel, with the plane of the exterior surface of the window clearly offset from the plane of the exterior surface of the body of the automobile. However, this arrangement alters the overall appearance

  of the motor vehicle and interrupts the laminar flow

  re air around the body, which results in a

  unnecessary aerodynamic drag and unpleasant noise.

  Recently, there has been an interest in the automotive industry

  increasing to vehicles with window panes which have exterior surfaces in the same plane or

  almost in the same plane as the contiguous surface of the box

  se. This arrangement is generally given the name of vi-

  be "flush" or "semi-flush" glass, and this is desirable

  to improve vehicle appearance and laminar flow

  re air, hence the reduction in aerodynamic drag

and noise from the wind.

  Several patents describe the provision of a vi-

  be close to or almost flush with the surface cbnti-

  wading of the vehicle body. Examples of these patents include United States of America patents

  n 4,409,756, n 4,562,676, n 4,455,785 and n 4,457 111.

  Although we know in the technique of moldings with passage channel for flush and semi-flush glass, it remains

  a need for better moldings with step channel-

  glass wise. These moldings must securely hold the window glass while allowing it to slide easily in the channel during its raising and lowering. The channels must also seal the interior of the vehicle against noise and climatic conditions and minimize window vibrations. It is also desirable that moldings to

  are inexpensive to make and easy to assemble

  during the construction of the vehicle. Consequently, 3. the present invention relates to an improved channel for the passage of glass, satisfying the preceding conditions.

  The improved molding of the present invention

  tion comprising a channel for the passage of glass comprises

  a support structure having, in a cross section

  - dirty, part in the shape of a "U" and part in the shape of

  "L". The "U" and "L" shaped parts consist of

  twin to define two channels with open ends

  directed in opposite directions. The "U" shaped part defines a channel intended to fix it to an edge of an automobile. An elastic element on the "U" shaped part improves the fixing of the channel to the flange. The "L" shaped part, in combination with a branch of the "U" shaped part, defines a channel intended to receive in sliding part of the edge of the window. A hollow tubular sealing element with at least one protruding element in the channel is intended to urge part of the edge of the glass to make a tight contact with the

outer branch of the canal.

  The present invention will be well understood during the

  following description made in conjunction with the drawings below

  joints in which: Figure 1 is a partial side elevation

  of a motor vehicle on which a movement is mounted

  glass channel passage according to the present invention

  tion; Figure 2 is a sectional view taken along line 2-2 of Figure 1, the edge of the door not being shown; Figure 3 is a sectional view, similar to Figure 2, but showing the molding without the glass

from the window.

  Now in connection with the figures, a

  lure with glass passage channel is represented in its 4.

  outline by the reference 10. As is illus-

  tré in Figure 1, the molding 10 extends around the upper and lateral parts of the opening 12 for window of the door 14 of a motor vehicle comprising a movable window 16. As best seen in Figures 2 and 3 , the

  molding 10 generally comprises, in a cross section

  versale, a U-shaped part 18 and an L-shaped part 19. The U-shaped part 18 defines a channel 20 for mounting a glass passage channel 10 on the edge of the door 14. A channel 22 for the passage of the glass is defined by the inner branch 26 of the U-shaped part 18 in conjunction with the part 19 having in

  cuts the shape of an L, having a branch 24 extending through it

  shot of the inner branch 26 and a branch 25 extends

  dant perpendicular to the branch 24. Inside

  of the glass passage channel 22 is a tubular element

  the hollow area 28 used to make the window 16 watertight

  the inside of the channel 22 and to urge the pane outward in the direction of the branch 25, so that the plane of the outer surface of the pane is almost flush or almost

  flush with the adjacent vehicle panel.

  While the U-shaped part 18 and the L-shaped part 19 of the molding 10 are described individually below, the technician will notice that a construction

  in one piece of the molding 10 is preferred, and that this

  this is illustrated in the figures. In general, the par-

  tie 18 in U shape and part 19 in L shape

  tent a reinforcing metal core 30 which is covered

  green of a conventional elastomeric material. In some uses, the core 30 may not be necessary

  or it may be only partial. The core 30 has general-

  lies a shape in a side elevation which allows its

  mounting in opening 12 of the window on all sides

  tees with the exception of the lower horizontal side 32 which must 5. be opened to allow the extension of the window 16. Any conventional sealing strip may be used along

  edge 32 in combination with molding 10 of the present

the invention.

  The mounting part 18, the cross section of which has the shape of a U generally constitutes a mounting means for fixing the molding 10 to a flange of the frame 12 of the door. Thus, the U-shaped part 18 has branches 26 and 27 joined by a core 29 which form the channel 20 for fixing the mounting part 18 to a flange. A rib 36 of large dimensions extends inward

  from branch 27 to enter channel 20 and pre-

  feels an arrow-shaped head 38 which cooperates with a projection 40 to facilitate the fixing of the channel 20 to a flange

  but resist removal of the canal. In opposition to the ner-

  vure 36 is a projection 46 provided on the inner branch

  rieure 26. The rib 36 and the projection 40 are shown.

  on branch 27 of mounting part 18, but for

  alternatively lie on the inner branch 26

  with the opposite projection 46 on the branch 27. Towards the outside

  laughing at the mouth of channel 20 extends a pair of lips

  sealing glasses 48 and 51, which are intended to come in

  seal tightly in the associated opening of the door. The glass passage channel 22 is defined by the L-shaped part 19 in combination with the branch

  inner 26 of part 18 in a U shape.

  25 of the L-shaped part 19 is intended for hand-

  hold the edge of the window 16 received in the channel 22. The branch

  che 50 of the core 30 extends over almost the entire length of the branch 25 so as to ensure the retention of the window 16

  in the channel 22. A lip 52 extends from the end

  closed moth of channel 20 to further assist in sealing

  of the molding 10 relative to the opening of the door.

  It is important that a structural arrangement 6. with the flush glass maintains the ease of sliding of the window 16 in the channel 22. It is also important

  a good seal is maintained between the molding 10 and the

  be made of glass 16 when the latter is in the closed position. Thus, a tubular element 28 for stressing and sealing is provided. The tubular element 28 has a side wall 54 connected to a side wall 56, which in turn is connected to the inner branch 26 of the U-shaped part 18. The side wall 54 is joined to the branch 24 of the part 19 L-shaped between its

  extremities. The tubular element 28 has a hollow interior 60.

  The side wall 54 of the element 28 has a pair of ribs 62 and 64 extending inwardly into the channel 22. Opposite the ribs 62 and 64, a rib 66 extends inwardly to enter channel 22

  from branch 25. Ribs 62, 64 and 66 carry

  preferably try flocking 68 or other material with low

  coefficient of friction on their surfaces coming into con-

  tact with the glass pane 16. The tubular element 28 has

  a shape in a somewhat penta-

  to improve the sealing of the glass 16 in the

  channel 22 and serves well to urge the glass outwards

  laughing to provide near or near glass arrangement

flush.

  The present invention is not limited to the exemplary embodiments which have just been described, it

  is on the contrary susceptible to modifications and varian-

  those who will appear to those skilled in the art.
