DRAFTEX DEVELOPMENT AG, Sohönbühl}, CH - 6 ^ 00 Zug U-shaped profile strip

The invention relates to U-shaped profile strips, for example for edging a circumferential edge or for sealing and Run a window pane. Such profile strips are used, for example, in car body construction.

U-shaped profile strips are in the form of U-shaped ones, for example flexible metal supports known, which in plastic or Rubber sleeves (mostly completely) are enclosed, if necessary by an expansion process · The metal support can be a Take a variety of different, well-known forms. For example, he can have a number of side-by-side U-shaped Have elements that are either completely separated from one another in the profile strip or with one another by short flexible ones Bridges are connected.

Such a U-shaped profile strip is flexible and sustains Nevertheless, the enclosed metal carrier has sufficient strength to securely grasp the edge surrounding the opening.

In practice, the automotive body takes a piece of the profile strip and presses it onto the surrounding edge, after which it is cuts according to the corresponding length. In some cases it will

In advance a piece of the profile strip as self-contained Sole fairy manufactured (e.g. by the manufacturer of the profile strip), the scope of which corresponds to the scope of the opening of the Kfζ body In this case, the bodybuilder takes the frame with the closed loop, adjusts it to the body opening and presses it into place.

Even if such structures may suffice in practice, it is precisely their flexibility (whether they are suitable for the bodybuilder In Supplied in strips or as a frame with a closed loop are) have disadvantages. The reason for this is because the bodybuilder has to decide for himself where to bend the profile strelfen in order to match the bends of the body bends adapt, and it can easily happen that he applies the bends somewhat imprecisely in relation to the length of the strip; e.g. he could unintentionally stretch or compress the profile strip a little. The consequence of this would be that the profile strip subsequently springs back and possibly separates from the edge when in use, which creates an unsightly sight and the protective properties of the strip against drafts and weather would be diminished.

The invention is based on the object of creating an improved U-shaped profile strip which is flexible and has good gripping properties, but additionally contains one or more pre-formed bends at predetermined locations with predetermined radii.

According to the invention, a U-shaped profile strip is created, which is bent according to a predetermined radius of curvature and which has a rigid reinforcement at the bend is there all the time to keep the shape.

Furthermore, according to the invention, a frame with essentially

The profile strip shown in Figure 1 is used to fit on the circumferential edge of the door opening of a motor vehicle body. He owns the shape of a U-shaped gripping element 5 with a metal » Carrier 6, which consists of U-shaped brackets 8, which are connected to one another by connecting pieces 10 lying in the longitudinal direction are, wherein the metal carrier 6 is a sheath 12 made of plastic or other material with inwardly protruding gripping lips 14 owns.

A sealing element 16 (FIG. 2), which could consist of cellular rubber, for example, can be attached to the gripping element 5. In use, the gripping element 5 grips the circumferential edge of a door opening and supports the Diohtelement 16 so that it extends around the door opening to which the door closes when in use and creates a seal against drafts and weather. In the absence of the Diohtelements 16, the gripping eleaent 5 mainly fulfills tasks of edging or protection.

The gripping lips 14 form seals against the edge and also support the holding of the gripping element 5 on the edge.

- 5 -809812/0643

The metal support 6 can take any other suitable form. For example, the U-shaped brackets 8 can be completely separated from each other be separated or, if connected, the connectors may occupy locations other than those shown Connecting pieces 10. Instead, the metal support could consist of wire loops.

There can be the same number of oval lips 14 on both sides of the indentation and the gripping lips can be the same size.

The sealing element 16 can be attached to the plastic casing 12 by gluing. Instead, however, the shell 12 and the Sealing element 16 can be made of sufficiently compatible material that they are pressed by double rod pressing can be used to achieve the various hardnesses desired.

In practice, the profile strip must fit on the circumferential edge of a certain door opening. To make that easier, will the profile strip to the car body builder in closed Loops or frames are supplied that fit on a specific door opening, i.e. they have in the appropriate places Corners with given radii and curvatures. Because, however, the profile strips are essentially flexible, care must be taken that the profile strip is kept in the correct shape, until it is attached to the surrounding edge. For this purpose, correspondingly curved reinforcing elements 18 made of metal are attached to the Curves of the profile strip attached.

For this purpose, the profile strip is attached to a jig during production and is given the required radii at the points where bends are provided, after which the metal reinforcing elements 18 are attached and then the profile strips in the required shape at the bends and

Hold on to curvatures.

The reinforcing elements 18 can thereby be attached to the profile strips be added so that they are firmly adhered to the sheath 12 "as shown in FIGS. 2-4. In Figure 2 are the Reinforcing elements 18 near the open end of the indentation while it is shown in FIG. 5 attached deeper in the indentation and below the gripping lips 14 will.

The reinforcement members 18 can be attached to the shell 12 by any suitable adhesive, such as a heated one responsive adhesive. If desired, the reinforcing elements 18 can be embedded in the shell 12, such as it is shown in FIG.

At each bend or corner there can be two reinforcing elements 18 or just one such element.

In Figures 5 and 6, the parts that correspond to the parts in the Figures 1 to 4 correspond, denoted by the corresponding reference numerals. Figures 5 and 6 show a modified one Form of reinforcement, which is a rigid, U-shaped reinforcement element 20 (preferably) made of metal, which is inserted into the indentation of the gripping element 5 at a point where a corner or curve is provided, and that holds the profile strip in the correct shape until it is in the surrounding edge is fitted. The reinforcing element 20 can be attached to the profile strip in that it is glued to the shell 12 is attached.

In FIGS. 7 to 9, the parts which correspond to the parts of the preceding figures are in turn with the corresponding parts

Reference numerals denoted. As shown in Figures 7 to 9, the reinforcing element 20 has spikes 22, which when the reinforcing element 20 comes into position in the gripping element 5, reach into the sheath 12 and that Hold reinforcing element 20 in position or support the plague holding. Glue can also be used (as already mentioned in relation to Figures 5 and 6), but the spikes have an additional effect in holding Positions. In the event that thorns are provided, the use of glue could be omitted.

The spikes can have any suitable shape and take any suitable location on the reinforcement member 20.

The reinforcing element 20 can also have other shapes, in each case thorns corresponding to the thorns 22 being attached can be.

In FIGS. 10 to 12, the parts which correspond to the parts of the preceding figures are in turn with the corresponding parts Reference numerals denoted. In FIGS. 10 to 12, the reinforcing element 20 has further spikes 24 which are located in extend in the opposite direction of the spikes 22, i.e. inwardly into the indentation. The thorns 24 are supposed to be one Make gripping contact with the edge when the profile strip is brought into position on it.

The mandrels 22 and 24 can have any suitable shape and occupy any suitable location on the reinforcement member 20.

As shown in Figures 10 to 12, the reinforcing element 20 has an asymmetrical cross-section and its spikes 24 are only on one side. However, it could also be symmetrical

Have shape (especially when the gripping lips 14 are symmetrical with respect to the gripping element 5), and in this case the spikes 24 can lie on both sides of the reinforcement element. The spikes 22 can be omitted if desired especially if glue or something else is used to help reinforce the reinforcement member 20 to be held in the gripping element 5.

Although the reinforcement element 20 in FIGS. 5 to 12 in asymmetrical shape is shown, wherein one side wall of the indentation is higher than the other, this is by no means essential, and the reinforcing member 20 may have a symmetrical cross-section.

The reinforcement members 18 and 20 can be used to hold the profile strip in any required configuration. Instead of producing the corner shapes shown in FIGS. 1, 5, 7 and 10, the reinforcing elements could for example be used ^{to produce curves of W} S "bends. In applications of profile strips - whether in completely closed loops or in shapes partially open loops - the profile strip does not lie in its entire length in the same plane, and the reinforcement elements can be used to hold the profile strip in such a configuration in more than one plane.

In the embodiments shown here, the sealing element 16 Reinforced (if provided) at the bends by inserting foam rubber or similar material into the hollow part.

The reference to door openings in motor vehicles in this specification excludes the reference to door openings of luggage and other spaces of Kfz.

Although the profile strips described and shown are intended to be adapted to the circumferential edge of a door opening Modified forms of construction can be used as a recess for leading windows on to fit a mounting groove or similar configuration as the border of a window opening. In such cases the profile strip must be provided with bends and curves, all of which are preformed and in these shapes by reinforcing elements, similar to the reinforcement elements 18 or 20, can be retained.

The reinforcing members 18 and 20 can also be used in cases in which the profile strips are formed in open (instead of closed) loop belts.
