Definitions
- the present invention relates to the field of vehicles, in particular that of motor vehicles.
- the invention refers more specifically to the sliding window sliding system of these vehicles, and in particular to the doors of vehicles provided with such a system.
- the panes referred to in the present invention are so-called flush panes, making it possible to obtain an exterior facade without recess between the pane and the structure which surrounds it.
- a guiding and sealing system for flush glass comprises an elastomeric profile formed in one piece.
- This profile is further reinforced by a metal frame.
- a first part of this profile is able to be made integral with the frame of the window, while a second part ensures the guiding and sealing of the movable glass.
- the latter is equipped with a shoe slidably mounted in a slide made integral with the profile. To do this, the slide has a hollow profile that faces the pad so that the latter can engage in the slide while being held captive.
- Document FR2642375 describes a flush window system for automobile doors.
- the internal face of the pane comprises a guide element intended to fit into a channel with a U-shaped cross section. making it possible to guide and seal the window laterally.
- Document EP642943 refers to a sealing element for flush glass.
- This element consists of a fixing body made of rigid thermoplastic elastomer with a U-shaped part for fixing it to the vehicle body. Adjacent to this part is an inverted U-shaped pane circulation channel. Inside this channel is an insert of the same general shape provided with two elastic sealing surfaces which slide respectively on the inner and outer faces of this window.
- Documents FR3041905 and WO2018 / 149832 both disclose a glazed device intended to be assembled to a door casing to form a motor vehicle door.
- This device comprises at least one movable glazed panel carrying, on its inner face, at least one guide shoe slidably mounted in guide rails. The latter carry a seal intended to come, via a lip, into contact with the movable glass panel.
- the first drawback of these systems lies in the fact that the shoe allowing the guiding of the window by sliding in the rail or guide channel can be hampered in its course by fouling, or even obstruction, of the guide channel because nothing allows to hide or protect this channel when the window is open.
- the window leaves free access to any dust, dirt or foreign body that may infiltrate the guide mechanism and hinder it.
- the second disadvantage of these systems lies in the fact that the seals, equipped with a sliding lip on the internal surface of the glass as presented in these systems, have a poor efficiency against dust and / or water ingress. which can be sources of contamination for the guiding device of the window.
- the present invention suggests a guide device for a sliding window of a vehicle, comprising:
- the sliding surface of the slide is of male form and the shoe has a surface of female form receiving said sliding surface .
- the male shape of the slide surface of the slide is preferably a convex shape
- said female surface of the pad is preferably a concave shape.
- the convex and concave shapes are smooth, namely without apparent irregularity. It will be understood that said female and male shapes can be considered, in other words, to be male-type and female-type shapes, respectively.
- the male shape of the sliding surface of the slideway prevents any obstruction or hindrance of the skate in its movement. Furthermore, this male shape is advantageously not very favorable to the accumulation of dust or dirt on the sliding surface of the slide. In addition, even in the event of an accumulation of dust or dirt, the latter would be easily and immediately removed with each passage of the pad.
- the particular shapes of the contact surfaces of the slide and the shoe make it possible to ensure efficient and unhindered guidance of the sliding window despite conditions which, for the systems known from the prior art, would be favorable to fouling or seizure of the sliding window guide mechanism.
- this guiding device further comprises a structure configured to support:
- said structure is a fixed structure which can form a frame for the sliding window.
- the slide is also an integral part of said structure.
- the combination of the latter with the structure can easily be achieved in one piece.
- this combination makes it possible, by simplifying the system as a whole, to reduce the number of parts to be produced and to be installed.
- each of the first and second seals comprises, at one end intended to be in contact with the pane, a pair of sealing lips constituting a double sealing barrier, in particular against solid particles and / or liquids.
- the first and second joints are configured to be kept plugged into said structure.
- the first seal is plugged into a groove made in this structure and is held there by means of a hooking profile that have the first seal and, in correspondence, said groove.
- the second seal is plugged into a projection of the structure and is held there by means of a hooking profile that the second seal has and, in correspondence, said projection. More preferably, this projection is substantially perpendicular to the inner face of the window.
- the second seal further has, on either side of this projection, a heel bearing against the structure and / or the door frame to which this structure can typically be attached.
- the structure is further configured to be attached to a door frame.
- the second seal may have at least one masking lip configured to cover an attachment element of the structure to the door frame.
- the invention also relates to a vehicle door, preferably a motor vehicle door, comprising a guide device for a sliding window according to any of the embodiments presented in the present description.
- the invention also relates to a vehicle, in particular a motor vehicle, comprising a sliding window guide device according to one of the aforementioned embodiments.
- FIG. 1 shows, in schematic form, the profile of a vehicle in which the device of the present invention can be arranged therein;
- FIG. 2a illustrates, in schematic form, the device of the present invention in a sectional view along the line II-II of FIG. 1 to locate, in particular, the main elements;
- FIG. 2b illustrates the device of the present invention in a view identical to that of FIG. 2a to locate details.
- this shows the profile of a vehicle in which the device of the present invention can be arranged therein.
- this vehicle is preferably a motor vehicle.
- the device of the invention could however also be fitted to any other type of vehicle comprising at least one sliding window 1.
- This window is typically movable in sliding up and down and vice versa.
- the mechanism which enables the sliding movement of the window to be actuated is not part of the object of the invention and will therefore not be described in the present description. It will simply be mentioned that any type of mechanism, manual or electric, can be used to raise and lower the window 1 between its closed, open and ajar positions.
- the window 1 of this vehicle is preferably a side window of the vehicle, in particular a door window 2 of this vehicle. More specifically still, this pane is preferably a flush pane, in the sense that it makes it possible to obtain an external facade 3 without a setback between the pane 1 and a structure 11 which, preferably, the frame (Fig. 2a). , 2b).
- This structure can typically be a fixed frame framing the window 1.
- this structure comprises in particular a cover 12 of the door frame.
- FIG. 1 indicates a section II-II more particularly integrating the window 1 of the front door of the vehicle. This section is shown schematically in Figs. 2a and 2b which will now be described.
- FIG. 2a shows a simplified sectional view along the line II-II of FIG. 1.
- the main elements which emerge from this section are in particular marked.
- FIG. 2a the elements of details have essentially been identified in FIG. 2b, which represents the same section as that of FIG. 2a.
- FIG. 2a we recognize the outer facade 3 which is essentially made up of the window 1 and the trim 12 of the door frame. Note in particular that these two elements are at the same height so that there is noticeably no setback caused by either of these elements. This characteristic makes it possible to define the window 1 as being a flush window.
- the device of the invention is particularly suitable for such windows, without this being a necessary condition, however.
- the first object of the invention relates to a guide device for a sliding window 1 of a vehicle.
- This device comprises at least one sliding shoe 20, configured to be integral with the window 1, and at least one slide 25 provided with a sliding surface 26 intended for guiding the sliding shoe 20.
- the sliding surface 26 of the slide 25 is of so-called male shape, typically convex, and the pad 20 has a surface 22 of female shape, typically concave, receiving the sliding surface 26 of the slide 25.
- the female-shaped surface 22 matches the male form that the sliding surface 26 has.
- the surface 22 can also be defined as a female surface and the sliding surface 26 as being a male surface.
- the sliding surface 26 of the slide 25 has a convex shape, preferably smooth, namely without apparent roughness.
- this convex shape is preferably still essentially circular.
- the female surface 22 of the pad 20 is therefore concave, preferably without apparent roughness.
- this concave shape is also preferably essentially circular, so as to match the sliding surface 26 of the slide 25.
- Other corresponding male (or convex) and female (or concave) surfaces could of course be adopted. for the slide 25, respectively the shoe 20.
- these surfaces are strictly convex, respectively concave, in the sense that they themselves have no additional concavity.
- the sliding surface 26 of the slide 25 prevents any obstruction or fouling which would make it possible to block or hinder the movement of the pad 20 which runs through it.
- This makes it possible to guarantee optimum operation of the guiding and sliding of the window 1, even under unfavorable, or even particularly difficult, conditions.
- Such conditions may for example involve splashing dirty water or muddy water, as well as splashing solid particles such as dirt from tracks, sand, leaves or other mineral or organic matter on the slide 25, in particular. when window 1 is lowered or ajar.
- this male or convex shape of the sliding surface 26 constitutes the most advantageous shape when it comes to ejecting dust or other solid particles or dirt which would have stuck to the slide 25.
- the male shape of the sliding surface 26 is oriented in the direction of the outer facade 3, which obliges the female surface 22 of the pad to be oriented opposite, namely to be turned in the direction of the vehicle interior. Therefore, this female surface 22 is protected by the back 23 (Fig. 2b) of the pad which acts as a protective screen or shield against the projection of any foreign element coming from the outside.
- the sliding surface 26 of the slide 25 and / or the female surface 22 of the pad 20 is made of a material with a low coefficient of friction and preferably of great hardness in order to benefit from low wear in the time.
- the device of the invention further comprises the structure 11 and the latter is configured to support:
- a second seal 40 arranged between this structure 11 and an inner face 4 of the window.
- the second seal 40 is arranged on the lateral periphery of the pane 1.
- first seal 30 is located on the front 3, typically between the trim 12 and the window 1, while the second seal 40 is located to the right of the window 1, on the side of its inner face 4.
- the first and second joints 30, 40 are essentially maintained in these positions by the structure 11.
- the first and second seals 30, 40 also help to preserve any fouling of the guiding device of the window 1 and, thereby, to prevent any discomfort, seizing or even blocking of this device.
- the slide 25 is of elongate shape, namely elongated.
- the slide can be rectilinear in shape without this being a determining characteristic.
- this slide has a length which is at least equivalent to that of the travel of the sliding window 1.
- the pad 20 can be appreciably shorter, its primary role being to guide the window 1 in its sliding movement.
- several pads 20 can be mounted on the same slide 25. Each of these pads can, for example, be fixed by gluing against the inner face 4 of the pane 1, in particular at the lateral periphery of the latter, namely on a side edge of the window 1.
- the slide 25 is an integral part of the structure 1 1.
- the slide and the structure 1 1 can be made in one piece, namely so monolithic, for example by molding.
- this characteristic contributes to the reduction in the number of parts which constitute the device of the present invention, which also makes it possible to lower the manufacturing costs and to reduce the time spent on assembly and maintenance.
- each of the first and second seals 30, 40 comprises, at one end intended to be in contact with the window, a pair of sealing lips 31, respectively 41, constituting a double sealing barrier, in particular against solid particles and / or liquids.
- the doubling of the lips 31, 41 in contact with the window 1 makes it possible to increase the efficiency of the sealing of the channel 5 against liquid and / or solid particles coming from the outside.
- the first seal 30 is above all a seal dedicated to sealing against dust, while the second seal 40 is itself more dedicated to providing a seal against liquids, in particular water splashes.
- the third seal 50 illustrated and marked in FIG. 2a is a door seal which is shown only as an indication, in particular for a better understanding or consistency of the sectional view of this figure.
- first and second joints 30, 40 are preferably configured to be kept plugged into the structure 1 January.
- the first seal 30 is plugged into a groove 13 formed in the structure 11 and is held there by means of a hooking profile 33 that have the first seal 30 and, in correspondence, the aforementioned groove 13.
- the second seal 40 is plugged into a projection 14 of the structure 11 and is held there by means of a hooking profile 44 that have the second seal 40 and, in correspondence, the projection 14 above. .
- this projection 14 is substantially perpendicular to the inner face 4 of the pane 1.
- the hooking profiles 33, 44 can be the same or different, as shown in FIG. 2b.
- the hooking profile 33 consists of a ridge, a protrusion or a ridge which may also form part of the groove 13 (as is the case in Figs. 2a and 2b) that of the seal 30, in particular of the portion of this seal inserted into the groove 13.
- this ridge, prominence or ridge there is a groove, for example a V-shaped groove, formed either in the seal 30 (as is the case in Figs. 2a and 2b), or in groove 13.
- the hooking profile 44 imagined to hold the second seal 40 has a shape reminiscent of that of the point of a harpoon. Although other shapes could also be considered, this harpoon point shape advantageously allows the second seal 40 to be easily plugged into the projection 14 while making its removal difficult once plugged in. Thus, this hooking profile promotes good retention of the second seal on the projection 14.
- the orientation of the projection 14 advantageously makes it possible to best take up the compressive forces exerted by the pressure of the pane against the second seal 40, more precisely through of the pair of lips 41 of this seal. This particular orientation also prevents any loosening of the second seal 40 from the projection 14 on which it is plugged.
- the resumption of the compressive forces acting between the projection 14 and the second seal 40 is also favored by the arrangement of a heel 45 which the second seal 40 has, on either side of the projection 14.
- This pair heels 45 is configured to bear against the structure 1 1 and / or against the door frame 6 to which this structure 1 1 can for example be fixed.
- This pair of heels helps to relieve the projection 14 on which this second seal 40 is inserted and reinforces the stability of this seal, in particular against its loosening.
- This pair of heels finally contributes to the isostatic positioning of the second seal 40.
- the structure 1 1 is further configured to be fixed to a door frame 6 by means of a fixing element 7 which can be a rivet, a bolt or any other adequate element.
- the second seal 40 can also have at least one masking lip 47 configured to cover the fixing element 7 which connects the structure 1 1 to the door frame 6.
- the structure 1 1 also comprises a lug 17 for maintaining the masking lip 47 by a free end of the latter, for example by sliding the free end of the masking lip 47 under the lug 17 so that this lip is in slight compression, as shown in FIG. 2b.
- a lug 17 for maintaining the masking lip 47 by a free end of the latter, for example by sliding the free end of the masking lip 47 under the lug 17 so that this lip is in slight compression, as shown in FIG. 2b.
- other suitable ways for maintaining the masking lip 47 could also be implemented.
- the advantage provided by the lug 47 lies in the fact that the installation of the masking lip, after fixing the structure to the door frame, is very rapid and can be carried out without tools. Thanks to the masking lip 47, the fixing means 7 is concealed, in particular when the window 1 is lowered. In addition to the aesthetic gain, the arrangement of the masking lip 47 makes it possible to protect the parts sensitive to fouling and to water infiltration which are the assemblies, such as that constituted by the fixing means 7 illustrated as an example in the Fig. 2a and 2b. In addition, this masking lip offers additional grip for the second seal 40, which further promotes its retention.
- a functional clearance 8 is provided to the right of the slide 25, between the structure 1 1 and the door frame 6.
- this set 8 makes it possible to ensure a stress-free installation of the structure 1 1 on the door frame 6, in particular when an axial displacement of these two parts is imposed by the position of the holes made in these parts in order to be able to assemble them by the fixing means 7.
- the clearance 8 advantageously makes it possible to tolerate such an axial displacement before the structure 1 1 abuts against the door frame 6 and deforms the axis or the sliding path of the slide 25.
- the second seal 40 is further configured so as to be able to cover a joint end 16 of the structure 1 1 with the door frame 6.
- This covering is marked in FIG. 2b by the blister 46 of the second seal 40.
- This blister 46 acts as protection, in particular against water infiltration at the level of the joint 16. In addition, it helps to once again improve the grip of the second joint 40.
- the door frame 6 is preferably formed from a double wall so as to constitute a double sealing barrier. Also, this double wall significantly improves the rigidity of the door frame. More preferably, the door frame 6 forms a hollow profile, which makes it possible to benefit from a structure that is both robust and light.
- the structure 1 1 comprises the cover 12 of the door frame.
- the latter can form an integral part of this structure or be attached, for example by gluing, against this structure as illustrated in FIGS. 2a and 2b.
- the invention also covers a vehicle door, for example a motor vehicle door, comprising a guiding and sealing device for sliding window 1 according to any one of the embodiments described above.
- the invention also relates to a vehicle, in particular a motor vehicle, comprising a guiding and sealing device for sliding window 1 according to any one of the aforementioned embodiments.
- a vehicle or motor vehicle can thus comprise a door as defined above.
