Abstract

A window frame arrangement, such as for a window opening carried by a vehicle door, is described for use where a stiff window frame is provided with a smoothly radiussed region across a change in direction, such as a corner (14), of the opening. Two separate sealing and guiding strips made of flexible material, each defining a window-glass receiving channel, have respective mitre-cut ends joined together to form a sharp angle at the corner (14) which is outside the smoothly radiussed region of the frame there. One of the sealing and guiding strips comprises extruded material defining a channel (64) which embracingly grips a flange (58) forming part of the window frame. The flexible material defines a small lip (72) positioned for contacting the outside of the window glass (12), and is extended to provide a limb (74) carrying a larger lip (78) for contacting the inside surface of the window glass (12). This limb (74) lies alongside a panel part (54) which is part of the window frame and is secured thereto by an integral projection (82). The flexible material defines a hollow chamber (90) at the end of the limb (74). In the smoothly radiussed region of the window frame, the window frame panel (54) has a correspondingly greater and progressively varying length than elsewhere, and over this region the flexible material is cut through at the wall of the hollow chamber (90) and a separate edge formation part (100) is moulded onto the strip (and also onto the second strip meeting it at the sharp corner), and carries a cosmetic lip (102) which extends over a flange (62) at the edge of the panel (54). Along the remainder of the strip, outside the smoothly radiussed region, the flexible material adjacent the hollow chamber (90) defines an integral cosmetic lip.

Two

bar parts

16 and 18 have diagonal plane and link together at sharp angle 14 places.

The rigid frame frame that

bar part

16 and 18 are installed on it only partly illustrates in Fig. 1 and 2.The mode that the structure of this window frame and

bar part

16 and 18 are installed in wherein will be described below.

At sharp angle 14 places, window frame forms fillet smoothly, and shown in the dotted line of Reference numeral 19, and this part of framework is by 20 coverings of folding lobe spare, so that form the part of sealing and guide groove 10 by the mode of the following stated.

By the following mode that describes in detail, for example plastics or rubber are made by for example pushing thereby sealing and gib block groove 10 are by flexible material.It is designed to be convenient to be provided for edge Weather sealed of wind glass and makes the low friction of mobile maintenance of glass.

Fig. 3 shows along the IV-IV line of Fig. 2 promptly along the cross section of B post intercepting.The rigid frame frame totally represented by Reference numeral 21, and it comprises rigid channel, thereby by crooked on the outer panels 22 of motor vehicle door and make sweep be shaped to the flute profile formula subsequently to form this rigid channel.Window frame 21 comprises this wainscot 23,24, and they engage to form flange 26.

Bar part 16 is made by the plastics or the elastomeric material of extruding, and has the single-piece groove shape, and it comprises base portion 28 and sidewall 30,32.Along its remote edge, sidewall 30 extends so that form lip (" cosmetic lip ") 34 along a direction, it covers on the edge of flange 26 and along other direction and extends so that form longer and gentleer lip 36, and this lip 36 partly extends the opening that traverses this groove.The remote edge of wall 32 extends to form short flexible lip 38.Another lip 40 is near the base portion 28 of groove.When whole window pane 12 was vertically slided, it was led by lip 36,38,40 in this groove.The surface of the lip that these contact with wind glass 12 is advantageously covered by the short flannel layer or is covered by other suitable low-friction coating.

The outside of the base portion 28 of bar part 16 has the lip 44,46 of short outside projection, and it helps bar part 16 is fixed in the groove of window frame 21.

The different piece of bar part 16 can have different hardness.

Fig. 4 is the section drawing along the III-III line intercepting of Fig. 2.Wherein, window frame forms by the overall expression of Reference numeral 50 and by the

panel

52,54,56 of door, and these panels are bonded together so that form the flange 58 of an

outside projection.Panel

52 and 54 is separated from each other along the direction of leaving flange 58, also links together once more subsequently so that form another flange 62 that is bonded together once more so that form hollow space 60.

Bar part 18 is also by plastics or the monolithic extruded groove 64 of making and limit encirclement flange 58 of elastomeric material, so that bar part 18 is held in place.Extruded material can integrally carry the lip 66 that extends internally, so that help the fix in position on this flange with sealing and gib block, and reinforcing load member 67 can be embedded in the extruded material.This reinforcing load member 67 can be made by any suitable material than rigidity, for example metal or plastics.

The extruded material of this part carries bigger flexible sealing lip 68 on a lateral wall of groove 64, when motor vehicle door 8 is closed, and the inside ceiling panel 70 of sealing lip 68 sealer motor-cars.

Material carrying one on the outside of the base portion of groove 64 can reentrant lip 72.Extend forming an arm 74 near the material of the opening of groove 58, this arm is put and is leaned against on the door face board 54 and terminate in the lip (" cosmetic lip ") 76, and this lip 76 surrounds the edge of flanges 62.In addition, the far-end of arm 74 integrally carries bigger flexible lip 78, and it extends so that these lips jointly are defined for the groove of admittance (shown in the dotted line) whole window pane 12 towards lip 72.Another lip 80 partly extends the base portion that traverses this groove.

The surface of the

lip

72,78,80 that contacts with whole window pane 12 has short flannel layer 42 or other suitable low-friction coating.

Arm 74 also is pressed on the window frame by the protrusion 82 of elastically deformable, and this protrusion 82 has the head 84 of expansion, and it is pushed to pass the perforate 86 on the panel 54 and to enter hollow space 60.After passing aperture 86, head 84 reinstatements of expansion and be pressed against on the panel 54 around the edge of perforate 86.

Should be noted that the plastics of extruding of bar part 16 shown in Figure 3 or elastomeric material are provided with cavity or the chamber 90 near the longitudinal extension of the far-end of groove sidewall 30.The hollow chamber 90 of similar longitudinal extension can be arranged in the material of bar part 18 shown in Figure 4, and this hollow chamber is positioned at the far-end of arm 74.

With reference to Fig. 2, window frame 12 comprise (shown in the dotted line) at the sharp angle two ends part 19 of bridge joint smoothly.In other words, door face board 23,24 (referring to Fig. 3) is in position (along the direction towards window center) the progressive extension on length near sharp angle 14, and this increase on length becomes big along the B post gradually towards the direction of sharp angle 14.Similarly,

door face board

52 and 54 length (referring to Fig. 4) increase gradually along the direction of inside ceiling panel towards sharp angle 14.

Fig. 5 shows along the section drawing of the line VI-VI intercepting of Fig. 2, the more close sharp angle 14 of cross section IV-IV that this section ratio is shown in Figure 3.Fig. 5 shows the general shape of window frame, and bar part 16 is roughly similar to Fig. 3, but the length of panel 22 and 24 has increased.

Similarly, Fig. 6 shows along the section drawing of the line V-V intercepting of Fig. 2, the more close sharp angle 14 of cross section III-III that this section ratio is shown in Figure 4.Wherein, the structure of the structure of window frame and bar part 18 and shown in Figure 4 roughly the same, but the length of

panel

52 and 54 has increased.

As mentioned above, when sealing that is configured to window and guide groove 10, the sealing that separates and the

gib block part

16 and 18 that have the structure of Fig. 3 and Fig. 4 respectively are extruded, and wherein an end of each bar part has diagonal plane, and two tangent plane ends are at contact of sharp angle 14 places and joint.Yet, because (as shown in Figure 5) panel 23 and 24 and the length of

panel

52 and 54 increased, therefore need in the zone of sharp angle 14, change and seal and the structure of

gib block part

16,18.

As shown in Figure 5, this is so to realize for (for a bar part 16), promptly by along near the wall of hollow chamber 90 and cut by the dotted line that Reference numeral 92 (referring to Fig. 3) is represented and to wear extruded material, remove cosmetic lip 34 thus.Similarly, as shown in Figure 6, along near the wall of hollow chamber 90 and cut by the dotted line of Reference numeral 94 (referring to Fig. 4) expression and to wear extruded material, remove cosmetic lip 76 thus.Certainly, these cutting operations are only implemented on the length part of the close sharp angle 14 of

bar part

16,18, and wherein the length of the formation respective window frame part of panel part has prolonged.

Should be appreciated that this cutting can implement at the diverse location outside Reference numeral 92 or 94.

After cosmetic lip 34 and 76 was cut by this way, two ends (after cutting sth. askew) of sealing and

gib block part

16,18 were close together in mould.Molded operation but also makes that the folding lobe spare 20 (referring to Fig. 5 and 6) of the prolongation have cosmetic lip 102 is molded in place on two

bar parts

16,18 not only with the diagonal plane engaged at end together.This folding lobe spare 20 (only) engages with sealing and

gib block part

16,18 along the regional A of line of cut 92 (Fig. 5) and 94 (Fig. 6).In this embodiment, preferably only will roll over lobe spare 20 along regional A and be molded on sealing and the

gib block part

16,18, this is because this can be avoided making the short flannel 42 in area B to be subjected to the heat required in the molding process and the influence of pressure.This minimizing or prevented destruction for short flannel 42, so short flannel 42 has good and clean and tidy outward appearance, this short flannel intactly extends to the position of folding lobe spare 20 against lip 78.

In addition (or replacedly) can along the area B of line of cut 92 (Fig. 5) and 94 (Fig. 6) will roll over lobe spare 20 be molded into the sealing and

gib block part

16,18 on.Yet,, can advantageously will not roll over lobe spare 20 near the surface that is applied to lip 78 area B, but reserve the zone that does not have short flannel between short flannel 42 and area B if folding lobe spare 20 is molded on sealing and the

gib block part

16,18 in area B.Be applied to short flannel on this zone and may be molded process and destroy, and short flannel may have not good outward appearance, and not have appreciiable line clearly in folding lobe spare 20 and the position that lip 78 intersects.

The position of (Fig. 5) and the formed flange in position that intersects (Fig. 6) in the end of the

panel

52,54 that prolongs are intersected in the end that is enclosed in the panel 23,26 of prolongation by the cosmetic lip 102 of carrying at last molded folding lobe spare 20.

Fig. 7 and 8 is roughly corresponding to Fig. 4 and 6, but the window frame that bar part 18 is installed on it does not illustrate in Fig. 7 and 8.In Fig. 7 and 8, represent by identical Reference numeral with Fig. 4 and 6 corresponding components.

In Fig. 7 and 8, hollow chamber 90 is not formed in the extruded material, but is replaced by cavity 90A.Bigger flexible lip 78 has " bottom " 78A, and it is made by crumpling process, so that separate with the extruded material of cosmetic lip 76.Fig. 9 (only showing the part of Fig. 7) wherein shows the relative positioning of the adjacently situated surfaces 76A of the bottom far-end of 78A and cosmetic lip 76 in the squeezer outlet, and shows the clearance G between them.Yet, in the squeezer exit, being provided with suitable roll structure, it forces the far-end 78A of bottom 78 and fastening contact of surperficial 76A of cosmetic lip 76.Because material is just just extruded from squeezer, therefore be bonded to each other by securely coarctate these two parts of roll structure, (this can for example realize by the cross-linking process of proceeding after extruding) forms this chamber 90A thus.Therefore, in such a way, for the viewer towards for the groove of admitting whole window pane watches, the inaesthetic gap that can not see.As with two part force togethers and it is bonded to each other or the substituting of the scheme of adhesion, described part can not be bonded to each other so that they abut against each other by force together.

In the zone of sharp angle 14, the level and smooth fillet part 19 (referring to Fig. 2) of window frame is covered by folding lobe spare 20.Therefore as shown in Figure 8,94A along the line cuts so that make the material of material and cosmetic lip 76 of bottom 78A of lip 78 separate, and removes this cosmetic lip 76.Subsequently, carry out molded operation so that form the folding lobe spare 20 of the prolongation of carrying cosmetic lip 102, this cosmetic lip 102 is surrounded the end of the

panel

52,54 that prolongs, (referring to Fig. 6, not shown at Fig. 8).

In Fig. 8, shown folding lobe spare 20 is partly filled this cavity 90A.The material that should be appreciated that folding lobe spare 20 can fully be filled this cavity 90A, and making does not wherein have the space.

The regional A that folding lobe spare 20 is molded on the material of window channel can not see in the outside, so that block the back at the far-end of bottom 78A.Folding lobe spare 20 can only be molded on the window channel in regional A, perhaps its additionally (or alternatively) in area B, be molded on the window channel, wherein bottom 78 far-end 78A intersects with folding lobe spare 20.

Advantageously, in this embodiment, folding lobe spare 20 is made by TPE (thermoplastic elastomer), rather than is made by the EPDM (ethylene propylene diene rubber) of routine.Under the temperature required low molding temperature than EPDM, TPE can form and be molded on other parts.Therefore, the molding process that is used for TPE folding lobe spare is unlikely damaged in the bottom short flannel 42 at 78 far-end 78A place.

Yet, should be understood that folding lobe spare 20 can be made by EPDM (ethylene propylene diene rubber) (or other suitable material).If folding lobe spare 20 is made by EPDM and is molded on the window channel in area B, then it is preferably on the far-end 78A that does not make short flannel 42 be applied to bottom 78, and this is owing to short flannel in this zone may be molded the cause thermal damage of process and have not good outward appearance.

The use of TPE is favourable, and this is because its recycling more easily.

Along the B post of window frame, bar part 16 (Fig. 3 and 5) can by shown in Fig. 7,8,9 and described same way as carry out modification so that form chamber 90A rather than chamber or chamber 90.Molded operative configuration becomes the folding lobe spare 20 that

bar part

16 and 18 is joined together and will carry to the prolongation of cosmetic lip 102 to be molded on two bar parts, and wherein they intersect in the corner portion of window frame.

Although being the zone with reference to sharp angle 14, above description illustrates, but do not having to use same principle construction under the situation of sharp angle, for example the direction of other form of corner portion non-acute angle or crooked or bending changes, for example when A post or C post when roof is crossing.
