Description

DESCRIPTION:

The invention relates to a mounting device for a vehicle window with a sealing means arranged along a window edge and a number of holding elements that fix the vehicle window in the sealing means and which have pressing surfaces that partially rest on an outer surface of the window and partially on an outer wall of the vehicle.

In this assembly device, which is already known from practice, side windows of a bus, for example, are pressed into a sealant applied along the edge of the window in a window frame. An adhesive can be used as a sealant, for example. To hold the side windows in the sealant, a number of clamping pieces are attached to the outside of the vehicle. These rest with a pressing surface partly on the outer wall of the vehicle and partly on the outer surface of the window. The clamping pieces are usually hardwood clamping pieces, of which around six are required per window. After the sealant has hardened, the clamping pieces are removed. Then, to complete the assembly of the window, a carrier profile running the entire length of the vehicle is screwed to the outer wall of the vehicle and a cover or parapet strip is pulled onto this. This covers at least the lower edge of the side window, with this area being protected by additional

is sealed with rubber seals arranged on the cover or parapet strip.

The disadvantage of the previously known assembly device is that a corresponding number of holes must be drilled into the outer wall and/or into the frame tubes arranged below the side windows in order to attach the clamping pieces. After the sealant has hardened and the clamping pieces have been removed, these holes must be sealed again. This makes the assembly of side windows with the known assembly device relatively time-consuming and if the holes for the clamping pieces are not sealed properly, moisture can penetrate, which has a negative impact on the service life of the frame tubes or the outer wall of the vehicle.

The invention is therefore based on the object of improving an assembly device of the type mentioned at the beginning so that the assembly of the panes is simplified and interventions on the outer wall or frame tubes are not necessary.

This object is achieved in a mounting device with the features of the preamble of claim 1 in that an engagement element protrudes from the pressing surface for engaging in a gap formed between the vehicle window and the outer wall, which has at least one locking device for engaging behind the outer wall.

In this way, the retaining element with its engagement element can be easily inserted into the gap and

locked into place with the outer wall. Drilling holes for fastening the retaining element are no longer necessary. Furthermore, the retaining elements do not need to be removed, as they are covered by the cover or parapet strip that is later put on and can therefore remain in place. Instead of engaging behind the outer wall, the locking device can also be designed in such a way that it can be brought into engagement with, for example, corresponding projections or recesses of a frame tube or the like. To complete the assembly of the side window, the cover or parapet strips can be pulled onto a support profile in the manner described above or can also be attached to the retaining element. The retaining element is preferably made of a plastic material so that no corrosion occurs.

In an advantageous embodiment of the invention, the holding element is arranged in the sealing means and the pressing surface covers the gap to the outside. In this way, the holding element is held by the hardening sealing means in addition to gripping behind the outer wall and at the same time the sealing means displaced by the inserted engagement element is held back by the pressing surface.

In order to hold the pane in a certain position while the sealant hardens, it is also advantageous if the engagement element has a support surface on its upper side for the pane to sit on. In addition, the weight of the attached

Disc applies force to the locking device of the engagement element for better gripping of the outer wall.

In a simple embodiment of the invention, the engagement element is designed as a bracket that projects essentially vertically from the pressing surface and has a locking device that projects downwards from it. The open shape of the bracket makes it easier to insert the engagement element into the sealing means. The top of the bracket serves as a support surface in this context. After the sealing means has hardened, the sealing means that has penetrated into the open bracket fixes the holding element in the gap in addition to the locking engagement of the locking device.

In this context, it is also advantageous if the bracket is essentially U-shaped, with the U-legs being attached to the pressing surface and a type of tab protruding from the U-web as a locking device. The sealant penetrates into the opening between the U-legs and, after hardening, fixes the locking tab in its engaged position.

If the locking tab has a downward-protruding locking lug adjacent to its free end, the locking tab is elastically designed to easily grip the outer wall from behind. The locking tab and locking lug are designed in such a way that they wedge into a positive fit on the upper edge of an outer wall sheet.

Another way to lock the locking lug is to use small shaped brackets that are firmly connected to the frame, for example by means of point-jointing, into which the locking lugs can be locked. In this way, a special design of the outer wall panel is not necessary.

In an advantageous embodiment of the invention, the pressure surface is designed as the inner surface of a pressure plate. The pressure plate can be rectangular, for example, with the longer sides of the rectangle running in the longitudinal direction of the vehicle and the shorter sides of the rectangle running perpendicular to it. The thickness of the pressure plate can be relatively small, so that it can be easily covered by the cover or parapet strip.

In order to prevent the formation of condensation in the area between the pressure plate and the outer wall or side window or to remove water that has penetrated, it is also advantageous if a ventilation recess is formed in the pressure surface, extending essentially from the gap to the lower end of the pressure plate.

In this context, it is also advantageous if the ventilation recess is designed as a ventilation surface that is lower than the pressure surface and spaced from the outer wall. The pressure surface can enclose the ventilation surface on the sides and at the top. The gap formed between the outer wall and the ventilation surface is open towards the lower end of the pressure plate.

In order to easily attach the deck or parapet strip to the pressure plate, it is advantageous if a support element for holding the deck or parapet strip is arranged on the outside of the pressure plate opposite the pressure surface. In this way

There is no need to attach a support profile, which, with the current state of the art, had to be screwed to the outer wall of the vehicle over the entire length of the vehicle. As a result, these holes are no longer necessary, meaning that no moisture can penetrate through these holes. Furthermore, the attachment of the cover or parapet strip is made easier by the support element, so that the entire assembly of the side window is considerably simplified and accelerated.

In a further embodiment of the invention, the carrier element is detachably attached to the pressure plate. The pressure plate and carrier element can be connected to one another, for example, by means of a screw connection, positive connection or the like.

In this context, it is also advantageous if the support element is mounted so that it can be adjusted relative to the pressure plate. In this way, manufacturing tolerances can be easily compensated, for example to ensure that the deck or parapet strip is perfectly aligned. The support element can be adjustable both horizontally and vertically relative to the pressure plate.

In a simple embodiment of the invention, the carrier element is essentially plate-shaped, with its inner side resting at least partially on the outer side of the pressure plate and a

Longitudinal slot is formed. This means that the carrier element can be easily plugged onto the holding element and is held securely by the locking extension. By using a vertically running longitudinal slot, the locking extension can be moved in it, so that the carrier element can be adjusted at least vertically relative to the holding element.

In order to enable the locking extension to be easily locked into the carrier element, it is advantageous if the longitudinal slot is formed between two locking wings of the carrier element that protrude diagonally outwards. It is also advantageous if the locking wings are wider than the width of the locking extension. In this way, the locking extension is securely held by the locking wings along the entire longitudinal slot.

In order to easily enable a specific position of the carrier element relative to the support element at least in the vertical direction, it is advantageous if a large number of mutually engaging rows of teeth are arranged at least in areas on the inside of the carrier element and the outside of the holding element, which extend essentially perpendicular to the longitudinal slot. Depending on the number and design of the rows of teeth, a very precise positioning of the carrier element is possible to compensate for manufacturing tolerances. The locking extension can be easily moved along the longitudinal slot.

In order to further simplify the fastening of the cover or parapet strip to the support element, guide rails are arranged essentially perpendicular to the longitudinal slot at the ends of the support element for the detachable fastening of the cover or parapet strip, into which retaining arms arranged on the cover or parapet strip engage. In this way, the cover or parapet strip covering the transition between the side window and the outer wall can be easily pulled onto the support element. If the cover or parapet strip is damaged, it can be replaced just as easily.

In order to save material while maintaining the elasticity of the locking wings, it is also advantageous if the locking wings have elongated holes that extend essentially parallel to the longitudinal slot.

In order to simplify the installation of the cover or parapet strip and to simultaneously fix it in place when it is installed, it is particularly advantageous if an edge of the guide rail that is located on the outside relative to the retaining element has a greater thickness in a middle section. The retaining arms can be easily inserted into an open guide groove that extends essentially parallel to the rows of teeth, with the edge of the guide rail having a relatively small thickness at the beginning of the insertion. As the cover or parapet strip is pushed on further, the retaining arms are held in place by the

increasing thickness in the middle section of the guide rail is pressed outwards so that the fully pulled-on cover or parapet strips are securely held by the middle sections of the guide rails.

Depending on the length of the holding element in the longitudinal direction of the vehicle, in a further embodiment of the invention this is designed with at least two locking devices and/or locking extensions and the support element with a corresponding number of longitudinal slots. For example, the holding element can be designed with two locking devices spaced apart from one another, with a locking extension protruding approximately in the middle of this and engaging with a corresponding longitudinal slot of the support element. Furthermore, with two locking devices, two locking extensions associated with this are also possible, which engage in two associated longitudinal slots of the support element.

The engagement element of the holding element that engages in the gap can, for example, be long enough to allow both a pane with single glazing and a pane with double glazing to stand on the support surface. Accordingly, different holding elements can be used for single and double glazing.

Advantageous embodiments of the invention are explained and described in more detail below with reference to the figures attached to the drawing.

Figure 7 is a cross-section along line VII VII of Figure 6.

In Figure 1, the assembly device 1 is shown in the installed state. The assembly device 1 is formed from a holding element 5 and a support element 26. The holding element 5 rests with a pressing surface 8 partly on an outer surface 6 of a pane 2 and partly on an outer wall 7. The outer wall 7 is formed from a wall plate that is laterally attached to a partially shown framework tube 48. The framework tube 48 extends to the interior

of the vehicle, with the outer wall 7 forming the outer contour of the vehicle. In the direction of the vehicle window 2, the framework tube 8 projects upwards beyond the outer wall 7, with a gap being formed between the framework tube and the outer wall 7 in the area of a rounded corner of the framework tube.

The vehicle window 2 is arranged above the frame tube 8 and the outer wall 7, so that a gap 9 is formed between them. An engagement element 10 protruding from the pressing surface 8 of the holding element 5 engages in the gap 9. The vehicle window 2 is positioned on a substantially horizontal upper side of the engagement element 10. Opposite the vehicle window 2, a locking lug 20 is formed on the engagement element 10, which engages in a form-fitting manner in the gap formed between the outer wall 7 and the frame tube 48. The extent of the engagement element 10 in the direction of the vehicle interior is approximately twice as large as the width of the vehicle window 2.

A sealing agent 4, for example an adhesive, is arranged on the lower and inner edge of the window 3, within the engagement element 10 and above the frame tube 48. This extends to a profile strip 58, which stands on the frame tube 48 and has an upwardly extended leg that is concavely curved relative to the vehicle window 2. The upwardly extended leg extends essentially from the frame tube 48 to adjacent to the vehicle window 2. To accommodate an interior panel 52, the profile strip 58 has two

essentially semicircular receptacles 59 adjacent to the top of the framework tube 48. The right of the two receptacles 59 is continued upwards by the extended leg of the profile strip 58. The inner lining 52 has a shape similar to the Greek letter π . To be held in the receptacles 59, the inner lining 52 has two essentially vertical legs 54 and 55, which are curved at their free ends complementary to the receptacles 59. On the opposite side, the legs 54 and 55 end in a cover lining rising in the direction of the vehicle window 2. This is formed with a contact seal 53 at least in its end adjacent to the vehicle window 2.

From the engagement element 10, the holding element 5 extends approximately equal to the height of the gap along the outer surface 6 of the pane. Below the engagement element 10, the holding element 5 runs essentially parallel to the outer wall 7 with an extension that is two to three times the height of the gap 9.

The carrier element 26 is detachably attached to the holding element 5 by means of a locking extension 29. A large number of rows of teeth 35 are arranged between this and the holding element 5. These extend approximately over the entire contact area of the holding element 5 and the carrier element 26. The carrier element 26 extends approximately from the lower end of the vehicle window 2 to the lower end of the holding element 5 and is parallel

to this. On the side of the support element 26 opposite the holding element 5, the locking extension 29 protrudes from the support element 26 approximately in the middle of the latter. The support element 26 is designed with guide rails 38 and 39 at its top and bottom ends. These run essentially parallel to the support element 5 in a first section and are curved with their free ends in the direction of the support element 5 so that they have an essentially quarter-circular shape. A cover or parapet strip 27 is slidably mounted in a groove 42 formed between the guide rails 38 and 39 and the support element 26. This is pulled onto the support element 26 as an external cladding for the transition between the vehicle window 2 and the outer wall 7. For the slidable mounting of the cover and parapet strip 27, it has two holding arms 40 and 41, which at least partially engage in the grooves 42 of the guide rails 38 and 39. At its upper end 50, the cover or parapet strip 27 runs above the guide rail 38 in the direction of the vehicle window 2 and lies sealingly on the outer surface of the window. At its lower end 49 below the guide rail 39, the cover or parapet strip 27 runs in the direction of the outer wall 7, with a gap opening 51 being formed between the two.

In Figure 2, the holding element 5 from Figure 1 is enlarged and shown separately from the carrier element 26 or the vehicle window 2 and the outer wall 7.

The support element 5 is formed from a pressure plate 21, the inside of which is the pressure surface 8. The rows of teeth 35 are arranged on an opposite outer side 27 and extend approximately over two thirds of the height of the pressure plate 21 to almost its lower end 22. Approximately in the middle of the rows of teeth 35, the locking extension 29 protrudes perpendicularly from the outer side 25. It extends across the rows of teeth 35 over a width 33.

The engagement element 10 protrudes vertically from the pressure surface 8 slightly above the rows of teeth 35 on the outside 25. Its upper side 12, which also runs vertically to the pressure surface 8, is designed as a support surface 13. Adjacent to the pressure plate 21, the engagement element 10, designed as a bracket 14, has a groove 56. This runs along the pressure surface 8 in the upper side 12 of the bracket 14.

The locking device 11 protrudes downwards at an acute angle from the end of the bracket 14 opposite the pressure plate 23 in the direction of the pressure plate 21. The locking device 11 is designed as a locking tab 18, on the free end 19 of which the locking lug 20 is formed. The free end 19 of the locking tab 18 runs essentially perpendicular to the pressure surface 8, with the locking lug 20 protruding downwards in an approximately triangular shape from the underside of the latter.

Approximately from the bracket 14 to the lower end 23 of the pressure plate 21, a

A lower ventilation surface 24 is formed opposite this.

Figure 3 shows a plan view of the holding element 5 from direction III in Figure 2, i.e. a plan view of the outer side 25.

In one embodiment of the invention, the holding element 5 can be designed symmetrically to the dash-dotted cutting line 61. In another embodiment, the cutting line 61 forms a left edge of the holding element 5.

In the top view according to Figure 3, the holding element 5 is approximately square-shaped. Starting from the cutting line 61, a large number of rows of teeth 35 extend to the left of the locking extension 29, which are arranged parallel to one another and at the same distance from one another. The rows of teeth extend approximately from the cutting line 61 over half the distance to the locking extension 29. This is arranged approximately in the middle of the outside 25 relative to the transverse extent of the support element 5 and offset downwards relative to the height of the support element 5 from the middle. Above the locking extension, the bracket 14 is arranged on the inside of the holding element 5 opposite the outside 27. The bracket 14 is formed by two legs 15 and 16 protruding from the inside, which are connected to one another at their ends, with the locking tab 18 protruding downwards and towards the inside from the connected ends.

Below the bracket 14, on the inside opposite the outside, there is the ventilation recess 23 formed by the lowered ventilation surface 24 according to Figure 2. This runs approximately from the bracket 14 to the lower end of the holding element 5.

Figure 4 shows a section along the line IV - IV from Figure 3. The same reference numerals identify the same parts and are also partially mentioned.

The bracket 14 is essentially U-shaped. Its U-legs 15 and 16 extend from the pressing surface 8 to the U-web 17. The U-legs 15 and 16 run essentially vertically to the pressing surface 8, with the U-web running essentially parallel to it. The bracket 14 is arranged approximately in the middle of the ventilation surface 24, with the locking tab 18 protruding from the U-web 17 in the direction of the ventilation surface 24. At its end 19, the locking tab 18 has a locking lug 20 protruding from the plane of the drawing. The locking tab 18 has a width that is slightly less than the distance between the U-legs 15 and 16. The length of the locking tab 18 corresponds almost to the distance between the U-web 17 and the ventilation surface 24.

On the opposite side of the pressing surface 8 or ventilation surface 24, the locking extension 29 protrudes essentially vertically from the outer side 25. In the illustration shown in Figure 4, the locking extension 29 extends in extension of the locking tab

18. On both sides, the locking extension 29 has locking flanges 59 and 60 that protrude laterally. These are each the same height and shape. The lower locking flange 59 is approximately half the height of the locking extension 29 and the upper locking flange 60 is at the upper end of the locking extension.

On the left side of the locking projection 29, the section according to Figure 4 is laid through a row of teeth, so that the outer side 25 appears to have a step in this area.

In Figure 5, the carrier element 26 from Figure 1 is enlarged and shown separately from the holding element 5.

The carrier element 26 is designed essentially symmetrically to the center line 62. On the inside, a large number of adjacent and parallel rows of teeth 35 extend. On the opposite side, a locking wing 31 is visible, which extends over a width. Adjacent to the ends of the locking wing, the guide rails 38 and 39 are formed at the corresponding ends of the carrier element 26. The carrier element 26 is designed at these ends with approximately twice the thickness compared to the area with the locking wing 31. The guide rails 38 and 39 protrude outwards from the ends 63 protruding above the locking wings 31. Guide grooves 42 are formed between an edge 45 of the guide rails 38 and 39 and the carrier element 26. In

In a section 46, the edge 45 is formed with a greater thickness.

In Figure 6, the carrier element 26 is shown in a plan view from direction VI of Figure 5. The same reference numerals indicate the same parts and are only partially mentioned.

Analogous to the holding element 5, the carrier element 26 can also be designed symmetrically to the cutting line 61 or be limited by it. In an area 57 adjacent to the cutting line 61, the carrier element 26 has the rows of teeth 35, see Figure 5. The guide rails 38 and 39 extend essentially from the area 57 to the other end of the carrier element 26. Opposite a center line laid through the grooves 42, the guide rails 38 and 39 are designed with a greater thickness 47 in a middle section 46. The upstream and downstream sections of the guide rails 38 and 39 are each designed with a decreasing thickness when viewed from the middle section 46. A longitudinal slot 30 extends between the guide rails 38 and 39, which is laterally limited by two locking wings 31 and 32. While the longitudinal slot 30 extends over approximately the same extent as the rows of teeth 35, see Figure 5, the locking wings 31 and 32 are designed with a smaller width. Therefore, openings running transversely to the longitudinal slot 30 are formed at the respective ends thereof, which run approximately parallel to the grooves 42 or the rows of teeth 35 from Figure 5.

Approximately in the middle of the width, i.e. in the longitudinal direction of the longitudinal slot 30, elongated holes 43 and 44 are formed on the sides of the locking wings 31 and 32 opposite the longitudinal slot. These extend in the direction of the longitudinal slot 30 approximately over half the extent of the locking wings 31 and 32.

Figure 7 shows a section along line VII VII from Figure 6. The locking wings 31 and 32 protrude upwards from the inner side 28 of the carrier element 26 at approximately a 45-degree angle. The locking wings run towards each other, with the longitudinal slot 30 being formed between them. On the side opposite the inner side 28, the locking wings 31 and 32 run diagonally downwards from the longitudinal slot 30, with an approximately semicircular recess being formed between the locking wing 31 and the section 57 or the section adjacent to the locking wing 32. To the left of the locking wing 31, a row of teeth 35 is shown, which extends along the area 57 on the inner side 28. An edge area 63, see also Figures 5 and 6 of the carrier element 26, protrudes upwards over area 57 or locking wings 31 and 32. Its upper side runs essentially parallel to the inner side 28, whereby a guide rail 38 partially protrudes over the edge region 63 above the locking wings 31 and 32.

To the right of the locking wing 32, the carrier element 36 is designed with decreasing thickness, so that an engagement opening 64 is formed for separating the holding element 5 and the carrier element 6.
