Description

Technical Field

[0001] The present invention relates to a guide device for sliding glass windows, particularly for sliding glass windows of automobiles or motor vehicles, and a sliding glass window and module equipped with such a guide device. Background Technology

[0002] Existing technologies include FR-A1-2 747 345, JP-U-S59 182418 and US-A1-2020 / 215881.

[0003] Automobiles or motor vehicles are typically equipped with sliding windows, i.e., windows that can move relative to a door frame. For aesthetic reasons, it has been proposed that the outer surface of a vertical element guiding the sliding window to be laterally flush with the edge of the door frame adjacent to the window. This vertical element is typically a pillar of the frame or a vertical external trim piece mounted on the frame, such as a vehicle's "B" pillar. The fact that the window is horizontal relative to this vertical element is called "flush" because the outer surface of the window lies essentially in the same lateral plane as the vertical element.

[0004] In the following text, the qualifiers “inside” and “middle” are generally used to indicate the position of the lateral inward portion of a motor vehicle, while the qualifiers “outside” and “greater” are generally used to indicate the position of the lateral outward portion of a motor vehicle. These designations refer to the axial direction Y, which is defined by the plane XZ perpendicular to the longitudinal horizontal direction X and the vertical direction Z of the vehicle (see [link to relevant documentation]). Figure 1 and 2 ).

[0005] In the motor vehicle, the door frame 8 is equipped with a glass track seal 10 (Figures 1 to 4) designed to receive a sliding glass window. The sliding glass window includes a glass window 12 equipped with at least one guide device 14 fastened to the inner surface 12a of the glass window and capable of sliding the glass window vertically in the Z-direction either in a recess 16 of the glass track seal 10 or in a sliding track directly adjacent to the sliding glass track seal. Figure 1 and 2 As shown, guide device 14 is fastened, for example, near the rear edge 12c of the glass window 12, and another guide device can be fastened near the front edge 12d of the glass window. The door frame 8 is... Figure 1 As shown in the figure, while Figure 2 Not shown in the image. Figure 2 The positions of the glass slide seal 10 and the glass window 12 relative to the vehicle body side 7 are shown.

[0006] The glass slide seal 10 typically includes two rising strips 10b, 10c connected together by an upper strip 10a. One or each rising strip 10b, 10c has a generally U-shaped transverse section or cross-section comprising two axially connected inner branches 10b1 and an outer branch 10b2 (see connecting branch 10b3) connected together. Figure 4 These branches 10b1, 10b2, and 10b3 define recesses 18 between them. Strips 10b are mounted to the posts 8a of the corresponding door frame or to vertical decorative members 8b disposed on the frame, and the outer surface 12b of the glass window 12 is laterally flush with the outer surface 8b1 of the decorative member 8b.

[0007] The guide device 14 has an elongated shape and includes a fastening portion 14a and a guide portion 14b, which are made as single pieces. The fastening portion 14a extends along the elongation axis A of the guide device and has a surface 14a1, which is intended to be applied and fastened to the inner surface 12a of the glass window 12, for example, by adhesive bonding. The guide portion 14b extends along axis A and includes a surface 14a1 substantially parallel to the fastening portion 14a and the wall 14b1 of the glass window 12. The guide portion 14b is received in a recess 18 of the glass slide seal 10 and engages with an outer branch 10b2 of the glass slide seal by sliding.

[0008] exist Figures 1 to 4 In the prior art illustrated schematically, each longitudinal end of the guide portion 14b includes a free rib 14b2. Each free rib 14b2 extends outward from the wall 14b1, thereby providing an L-shaped cross-section for the guide portion 14b at each longitudinal end of the guide portion. Figure 4 The cross-sectional view is taken in a plane passing through one of these ends. Each free rib 14b2 has a length L1, L1' measured along axis A, which is shorter than the total length L2 of the guide device 14, for example less than 10% of that length L2. Figure 3 Between the two free ribs 14b2, the guide portion 14b has an I-shaped cross-section.

[0009] like Figure 4As shown, the outer branch 10b2 of the glass slide seal 10 has an outer groove 19 receiving the edge 20 of the decorative element 8b and an inner groove 22 receiving two free ribs 14b2. A wall 14b1 engages with the branches 10b1 and 10b2 to hold the glass window 12 in the Y direction, and is adapted to slide onto the outer branch 10b2 when the glass window 12 moves. The free ribs 14b2 engage with the side surfaces of the inner groove 22 to hold the glass window 12 in the X direction, and are adapted to slide onto these side surfaces when the glass window 12 moves.

[0010] Glass window 12 can be viewed from Figure 1 The indicated rising position is moved to Figure 2 The lowered position is shown. The glass window 12 is guided to its lowered position by the engagement of its lower free rib 14b2 with the inner groove 22 of the glass slide seal 10. (As shown) Figure 1 and 2 As shown, when the glass window 12 is in its lowered position, the strip 10b of the glass slide seal 10 must therefore extend along the entire length of the guide device 14. Consequently, the strip 10b has a relatively long length, with a large portion extending within the door frame 8 below the door's guide line B, and thus cannot be seen by the vehicle's occupants (see...). Figure 1 and 2 Without such a guiding device, the lower free rib 14b2 may be held in the Z direction by the lower end of the strip 10b, and the guiding device and the lower end of the glass window will not be guided and held in the X direction.

[0011] The movement of the glass window 12 is typically ensured by a motor installed within the door frame 8 or in the panel of that door frame. The power of the motor to move the glass window 12 is determined by considering the weight of the glass window and the frictional forces acting upon its movement. These frictional forces are borne by the glass track seal 10 and are slidably engaged with the glass window 12. Figure 1 and 2 The sealing lip 26, and mainly due to the guide device 14 sliding into the glass slide seal 10, and due to the slight difference in curvature between the glass window 12 equipped with its guide device 14 and the door and door frame: this difference in curvature will cause additional friction during the up and down movement of the glass window on the glass slide seal 10 by the wall 14b1 and the free rib 14b2.

[0012] This invention proposes a simple, effective, and economical solution to address at least one of the aforementioned problems. Summary of the Invention

[0013] Therefore, the present invention proposes a guide device for sliding windows, particularly for automotive sliding windows, the guide device being designed to be fastened to the window and mate with a glass track seal, the guide device comprising a body made of a single piece and having an elongated shape along an axis, the body comprising:

[0014] A fastening portion, which extends along the axis and has a surface configured to be fastened to the glass window, and

[0015] A guide portion, extending along the axis and having an L-shaped cross-section, includes walls substantially parallel to the surface and free ribs substantially perpendicular to the surface. The free ribs include a first side surface facing the fastening portion and a second side surface opposite to the first side surface.

[0016] The feature is that at least one of the first and second side surfaces is non-planar and includes alternating ridges and depressions.

[0017] The term "non-planar surface" according to the invention should be understood as a non-smooth surface, and conversely includes discontinuities such as ridges, depressions, protrusions, edges, etc. The surface may be contained within a single plane, or it may be curved, and therefore may be part of, for example, a cylindrical or spherical surface.

[0018] Unlike the side surfaces of the free ribs in prior art guide devices, at least one side surface of the free ribs in the guide device according to the invention is non-planar. Using non-planar side surfaces(s) allows for a reduction in the surface area of ​​the free rib in contact with the aforementioned glass slide seal, and thus reduces friction during the movement of the sliding window. Therefore, the power required to move the window can be reduced compared to the prior art, and it is thus conceivable to use a motor that provides less power than the prior art to move the window.

[0019] The guiding device according to the invention may include one or more of the following features, which may be separate from or combined with each other:

[0020] Both the first and second side surfaces are non-planar;

[0021] At least one of the first and second side surfaces is wrinkled or wavy.

[0022] The free ribs have a substantially constant thickness along the axis;

[0023] The shape of the free rib is wavy or corrugated;

[0024] The free ribs include alternating portions with a thickness E1 and portions with a thickness E2 different from E1;

[0025] The free rib is shaped like a pearl necklace.

[0026] The wall and the free rib of the guide portion have similar or the same length along the axis;

[0027] The guide portion includes a single free rib;

[0028] The wall is non-planar and / or has a non-constant thickness;

[0029] The wall includes an outer surface and an opposing inner surface, the free ribs extending from the outer surface, and at least one of the outer and inner surfaces is non-planar;

[0030] Both the outer and inner surfaces are non-planar;

[0031] At least one of the outer and inner surfaces includes alternating ridges and depressions;

[0032] At least one of the outer and inner surfaces is wrinkled or wavy;

[0033] The wall has a substantially constant thickness along the axis;

[0034] The wall is wavy or corrugated in shape;

[0035] The wall comprises alternating portions having a thickness E1 and portions having a thickness E2 different from E1;

[0036] The wall is shaped like a pearl necklace;

[0037] E1 is less than or equal to 0.85E2 or greater than or equal to 1.15E2;

[0038] E1 is greater than or equal to 0.30E2 or less than or equal to 1.7E2.

[0039] The present invention also relates to a sliding glass window, particularly a sliding glass window for automobiles, comprising a glass window and at least one guide device as described above, the at least one guide device being fastened to the inner surface of the glass window.

[0040] The present invention further relates to a module, particularly a module for automobiles, comprising:

[0041] As described above, sliding glass windows

[0042] A decorative element for the door frame, extending along the axis and including an outer surface intended to be substantially aligned with the outer surface of the sliding glass window, and

[0043] A glass slide seal comprising a strip extending along the axis, the strip defining a recess for receiving the guide portion, the strip having an outer branch having an outer groove for receiving an edge of the decorative element and an inner groove for receiving the free rib.

[0044] Advantageously, the first and second side surfaces of the free rib are adapted to slide onto the side surface of the inner groove, and the wall includes an outer surface adapted to slide onto a portion of the outer branch defining the outer groove.

[0045] Preferably, the length of the strip of the glass groove seal is less than 150% of the length of the guide device. This is in contrast to prior art where the strip of the glass groove seal has a length approximately 200% of the length of the guide device. This reduction in strip length allows for a reduction in the cost of the glass groove seal and module. This can be achieved through a single free rib extending along the entire length of the guide device. This feature allows for further weight reduction of the glass groove seal and facilitates its installation process.

[0046] The present invention further proposes a guide device for sliding windows, particularly for automotive sliding windows, the guide device being designed to be fastened to the window and mate with a glass track seal, the guide device comprising a body made of a single piece and having an elongated shape along an axis, the body comprising:

[0047] A fastening portion, which extends along the axis and has a surface configured to be fastened to the glass window, and

[0048] A guide portion extending along the axis, the guide portion including walls substantially parallel to the surface.

[0049] The feature is that the wall is non-planar.

[0050] This guiding device may include one or more features described and listed above, which may be separate from or combined with each other. Attached Figure Description

[0068] Figures 1 to 4 The prior art of the present invention has already been described and illustrated above.

[0069] Figures 5 to 8 The first embodiment of the present invention is shown.

[0070] Figure 5 It is similar to Figure 2 The view, and Figure 6 It is similar to Figure 3 The view.

[0071] Figure 5 The glass window 12 and the glass slide seal 10 described above are shown, and differ in two features from those described above. Figure 1 and 2 The glass windows and glass track seals in the glass.

[0072] like Figure 5 As shown, Figure 5 The length D of the strip 10b of the glass groove seal 10 is greater than that of the strip 10b. Figure 2 The length D' of the strip 10b of the glass slide seal 10 is short. Although the length D' represents approximately 200% of the length L2 of the prior art guide device 14 ( Figure 2 and 3 However, the length D represents less than 150% of the length L2 of the guide device 114 according to the invention, preferably less than or equal to 120%. Figure 5 and 6 Therefore, the strip 10b of the glass groove seal 10 includes a short portion extending below the strip line B, which allows for a reduction in the cost of the door frame or at least the module comprising the glass groove seal 10 and the sliding glass window 12 provided with the guide device 114 according to the invention.

[0073] The strip 10 of the glass groove seal 10 can be made of a single elongated piece or of two consecutive and independent elongated pieces, for example, the first piece extends above the strip line B and the second piece extends below the strip line B.

[0074] Although in fact these characteristics Figure 2 The guide devices according to the invention are shown on the rear side 12c of the glass window 12, but they can certainly be applied to the front side 12d of the glass window 12. This means that the glass window can be provided with guide devices according to the invention on either its front or rear side. In the case where the glass window is provided with two guide devices on its front and rear sides, only one of these guide devices may be according to the invention.

[0075] It is possible to reduce the length of the strip 10b of the glass groove seal 10 by means of the guide device 114 according to the invention, and in particular by the fact that the guide device includes a free rib 114b2 extending along the entire length of the guide device 114, i.e., from its lower end to its upper end.

[0076] The guide device 114 has an elongated shape and includes a fastening portion 114a and a guide portion 114b, both made as single pieces. The fastening portion 114a extends along the elongation axis A of the guide device and has a surface 114a1, which is intended to be applied and fastened to the inner surface 12a of the glass window 12, for example, by adhesive bonding. The guide portion 114b extends along axis A and includes a surface 114a1 substantially parallel to the fastening portion 114a and a wall 114b1 parallel to the glass window 12. The guide portion 114b is received in a recess 18 of the glass slide seal 10 and engages with an outer branch 10b2 of the glass slide seal by sliding.

[0077] As described above, the rising strip 10b of the glass slide seal 10 has a substantially U-shaped transverse section or cross section, and includes two axially connected inner branches 10b1 and outer branch 10b2 (see connecting branch 10b3) connected together. Figure 8 These branches 10b1, 10b2, and 10b3 define recesses 18 between them. Strips 10b are mounted to the posts 8a of the corresponding door frame or to vertical decorative elements 8b disposed on the frame, and the outer surface 12b of the glass window 12 is laterally flush with the outer surface 8b1 of the decorative element 8b.

[0078] The outer branch 10b2 of the glass slide seal 10 has an outer groove 19 for receiving the edge 20 of the decorative element 8b and an inner groove 22 for receiving the free rib 114b2. The wall 114b1 engages with the branches 10b1 and 10b2 to hold the glass window 12 in the Y direction, and is adapted to slide onto the outer branch 10b2 when the glass window 12 moves. The free rib 14b2 engages with the side surfaces 22a and 22b of the inner groove 22 to hold the glass window 12 in the X direction, and is adapted to slide onto these side surfaces 22a and 22b when the glass window 12 moves.

[0079] As described above, the glass window 12 can be moved from the raised position to the lowered position. The glass window 12 is guided to its lowered position by the engagement of the free rib 114b2 of the guide device with the inner groove 22 of the glass slide seal 10. Since the free rib 114b2 extends along the entire length of the guide device 114, it engages with the lower end of the strip 10b, which can be shortened as explained above.

[0080] According to the present invention, when the glass window 12 is moved by using a guide device 114 having one or more non-planar surfaces, the friction between the guide device 114 and the glass slide seal 10 is reduced.

[0081] The free rib 114b2 includes a first side surface 128 facing the fastening portion 114a and a second side surface 130 opposite to the first side surface 128. At least one of these side surfaces 128, 130 is non-planar.

[0082] Figure 7 and Figure 8 A first embodiment of the guide device 114 is shown, wherein both surfaces 128, 130 are non-planar. Each surface 128, 130 is wrinkled or wavy and includes alternating ridges 132 and recesses 134. The ridges 132 of surface 128 are laterally aligned with the ridges 132 of surface 130, and the recesses 134 of surface 128 are laterally aligned with the recesses 134 of surface 130, providing the free rib 114b2 with alternating portions 136 (including ridges 130) having a thickness E1 and portions 138 (including recesses 134) having a thickness E2 different from, and particularly higher than, E1. In this embodiment, the free rib 114b2 has a shape similar to a pearl necklace. Two adjacent portions 136 are separated by portions 138, and two adjacent portions 138 are separated by portions 136.

[0083] Preferably, the thickness difference between E1 and E2 is expressed as at least 15% of E1 or E2. In the present case, E2 is greater than or equal to 1.15E1. The thickness difference between E1 and E2 can be, for example, at most 70% of E1 or E2. In this case, E2 will be equal to or less than 1.70E1.

[0084] Figures 11a and 11c show that each ridge 132 may have a curved top (Figure 11a) or a flat top (Figure 11c). As shown in Figure 11c, the flat top of the ridge 132 located on surface 128 may be parallel to the flat top of the ridge 132 located on surface 130.

[0085] The shape of the raised top affects the contact type between the free rib 114b2 and the side surfaces 22a, 22b of the groove 22.

[0086] Figure 12a shows that the free rib 114b2 can contact the surface 22a in the contact area located on the top of the ridge 132. Figure 13a The free rib 114b2 is shown to contact surface 22b in a contact area located on top of the protrusion 132. The top of the protrusion 132 contacts surfaces 22a and 22b along a line U1 oriented in the Z direction. The contact line U1 is shown as a dot in Figures 12a and 13a. The height of the contact line U1 along the Z direction depends on the height or dimension of the free rib 114b2 along the Z direction.

[0087] Figure 12c This shows that the free rib 114b2 can contact the surface 22a in the contact area located on the top of the ridge 132. Figure 13a This illustrates that the free rib 114b2 can contact the surface 22b in a contact area located on the top of the protrusion 132. The top of the protrusion 132 contacts surfaces 22a and 22b along a region U2 parallel to the Z direction. The contact region U2... Figure 12c It is shown by lines in 13c.

[0088] Figure 9 and Figure 10 A second embodiment of the guide device 114 is shown, wherein both surfaces 128, 130 are non-planar. Each surface 128, 130 is wrinkled or wavy and includes alternating ridges 132 and recesses 134. The ridges 132 of surface 128 are laterally aligned with the recesses 134 of surface 130, and the recesses 134 of surface 128 are laterally aligned with the ridges 132 of surface 130, which provides a substantially constant thickness E for the free rib 114b2 along axis A. In this embodiment, the free rib 114b2 has a wave-like or corrugated shape.

[0089] Figures 11b and 11d show that each ridge 132 may have a curved top (Figure 11b) or a flat top (Figure 11d). As shown in Figure 11d, the flat top of the ridge 132 located on surface 128 may be parallel to the flat top of the ridge 132 located on surface 130.

[0090] The shape of the raised top affects the contact type between the free rib 114b2 and the side surfaces 22a, 22b of the groove 22.

[0091] Figure 12b shows that the free rib 114b2 can contact the surface 22a in the contact area located on the top of the protrusion 132, and Figure 13b shows that the free rib 114b2 can contact the surface 22b in the contact area located on the top of the protrusion 132. The top of the protrusion 132 contacts the surfaces 22a and 22b along a line U1 oriented in the Z direction. The contact line U1 is shown as a dot in Figures 12b and 13b. The height of the contact line U1 along the Z direction depends on the height or size of the free rib 114b2 along the Z direction.

[0092] Figure 12d This shows that the free rib 114b2 can contact the surface 22a in the contact area located on the top of the ridge 132. Figure 13d This illustrates that the free rib 114b2 can contact the surface 22b in a contact area located on the top of the protrusion 132. The top of the protrusion 132 contacts surfaces 22a and 22b along a region U2 parallel to the Z direction. The contact region U2 is... Figure 12d and 13d It is shown by a line in the middle.

[0093] According to other embodiments of the guiding device according to the invention, its wall 114b1 may have a non-planar outer surface 142 (intended to mate with the outer branch 10b2) and / or a non-planar inner surface 144 (intended to mate with the inner branch 10b1).

[0094] Figure 14 A guide device 114 with a wall 114b1 is shown, the shape of which, as described above, is a pearl necklace shape. Therefore, regarding... Figures 6 to 8 The description of the pearl necklace-shaped free rib 114b2 is applicable to Figure 14 Pearl necklace-shaped wall 114b1.

[0095] Figure 15 A guide device 114 with a wall 114b1 is shown, the shape of which is wavy or corrugated as described above. Therefore, regarding... Figure 9 and 10 The description of the wavy free rib 114b2 is applicable Figure 15 The wavy wall 114b1.

[0096] The illustrations and descriptions in Figures 11a to 13d also apply to Figure 14 and 15 The guiding device 114.

[0097] Depending on the number and location of the protrusions of the free rib 114b1, and even the number and location of the protrusions of the wall 114b1, the number and location of the contact area along the guide device can vary.

[0098] Figures 16a to 16d Various examples of the distribution of these contact areas are shown. In these non-limiting examples, the number of contact areas is three or four. Contact area Z1 is preferably located at each longitudinal end of guide device 114. This means that ridge 132 or a portion of ridge is preferably located at each longitudinal end of guide device 114.

[0099] When there are three contact areas, the third contact area Z2 can be located in the middle of the guide device 114, such as... Figure 16c As shown, or near one longitudinal end of the guide device 114, such as Figure 16a and Figure 16d As shown.

[0100] When there are four contact areas, such as Figure 16b As shown, contact areas Z1 and Z2 can be regularly distributed along the guide device 114.

[0101] Since the protrusions 132 on the surface 128 of the free rib 114b2 or the surface 142 of the wall 114b1 do not need to be laterally aligned with the protrusions on the opposite surface 130 or 144, the location and distribution of the contact area can differ between one surface 128, 142 and another surface 130, 144.
