FR2477998A1 - RIGOLE FOR AUTOMOTIVE VEHICLE DOOR ICE - Google Patents

Abstract

THE INVENTION RELATES TO A RIGOLE FOR DOOR ICE. ACCORDING TO THE INVENTION, IT INCLUDES A CHASSIS 3 FORMING THE UPPER PART OF THE DOOR; A BASE ESSENTIALLY HAVING A U-SHAPED GUIDE THROAT AND PLACED IN THE CHASSIS; AND AN ENLARGED PART 6 PROJECTING FROM THE BASE TO GUIDE THE GLASS IN THE U-SHAPED GUIDE THROAT. THE INVENTION APPLIES IN PARTICULAR TO THE AUTOMOTIVE INDUSTRY.

Description

The present invention relates to a channel

  for door glass for a motor vehicle.

  There is a traditional channel for a motor vehicle door window of this kind, which is shown in FIG. 4. In fact, the trough 1 has a base la having a guiding groove of the window configured in a U. which is placed in a frame 3 forming an upper part of a door 2, two lips lb, lb 'facing inwards, extending from the edges of the

  internal sides of the base can guide the window 4.

  The mark 5 designates a frame trim of the door surrounded by the frame in a manner similar to

  channel 1. However, with such a tradition

  as the amount of projection na "of the portion 1a of the base of each of the lips 1b, 1b 'which rests on the frame 3 is small and thus the guide width" b "for the window is narrow, this poses problems because the window 4 deviates from the width "b" of its insertion guide during its closing movement, which makes this closure impossible, and this can occur when the window oscillates laterally when it closes. or when it is spread laterally due to manufacturing tolerances or when it is sucked to swing laterally outward due to

  depression created during a fast run of the vehicle.

  The object of the present invention is to solve the above-mentioned traditional problem by enlarging a portion of a support portion of a window channel and

  making it protrude from its general surface.

  According to the present invention, the width of a guide has been substantially increased by forming at least one enlarged portion which projects outwardly from a

  part of support of a channel. Therefore, the possibility

  that the closing operation is pocketed as a result of

  the deformation of the window is eliminated.

  The invention will be better understood, and other purposes, features, details and advantages thereof

  will appear more clearly during the description

  explanatory which follows with reference to the accompanying schematic drawings given solely by way of example illustrating an embodiment of the invention and in which: - Figure 1 is a side view of a door according to the invention; - Figure 2 is a cross-sectional view taken on the line II-II of Figure 1; Figure 3 is a side elevational view of Figure 2, looking from the left in the drawing; and - Figure 4 is a view similar to Figure 2

  but illustrating the prior art previously explained.

  Figures 1 to 3 are views illustrating an embodiment of the present invention. The same benchmarks used to explain the traditional trench are used to designate their counterparts and their explanation will be omitted for the simplicity of the

description.

  By first explaining the construction, the portion of the bearing portion 1c of the channel 1 which is disposed near an upper portion of a front post (not shown) is enlarged and protrudes outwardly. of the general surface in one or two places, and this enlarged and protruding portion 6 has a guide surface 6a which is formed on its inner side to guide the pane 4. The area designated H contains this enlarged portion 6 of the channel 1, whose ends which comprise the general part, are formed by molding and adhere to the ends of the general part which is formed by extrusion. As the general part has the surface 6a guiding formed therein, it is necessary to give it a suitable rigidity. The enlarged portion 6 is of increased hardness and / or it contains a metal core or core 7 of sheet metal or the like inserted therein, as can be seen in FIG.

figure 2.

  With this construction, the amount of protuber-

  rance A of the bearing portion 1l of the channel 1 partially increases and the width B of the guide surface 6a of the insertion guide for the window 4 increases correspondingly, thus the deformation or deviation of the window from the guide surface 6 does not take place, even if there is an oscillating movement of the window 4 when it is sucked outwards due to a vacuum created around the window during the movement closing it, thus ensuring a regular closing movement. In this case, the enlarged part

  protruding 6 does not sag because of its rigidity.

  Of course, the invention is not limited to the embodiment described and shown which has been given by way of example. In particular, it includes all means constituting technical equivalents

  described means as well as their combinations if these

  These are executed according to his spirit and implemented

  as part of the protection as claimed.
