be where at least one page and possibly more as one side of a component with respect to the adjacent side something is off the vertical, e.g. by 0.5 to 3 ° .. This degree The perpendicularity is particularly advantageous for components that are manufactured by compression molding, because it allows them to be removed from the mold the component is relieved from the mold.

The term "substantially perpendicular" is intended to mean ™ also understand the cases where the flanges are slightly off the vertical, e.g. by 0.5 to 3, to the section or to the extension.

The projection is preferably provided on the second component because it makes the production of the component particularly easy when compression molding a partially cured sheet of reinforced thermosetting resin is facilitated. The lead is preferably located at the point between the extension k and the portion of the second component that passes through the extension is extended. It is also useful if the general plane of the projection is perpendicular to the at least part of said adjacent side forming section of the second component and to its extension and with this section and its Extension is connected. It is not necessary for the protrusion to extend the full length of the component on which it is protruding. see is, extends. Rather, he only needs to find out about a small Neren portion of this length to extend, or it can be provided several spaced projections.

The projection can be in the form of a support and guide for support of the first component at a distance from the extension of the second component with a hollow approach.

Preferably, parts are cut away from the projection in such a way that a guide approach is given which is in a corresponding Recess of the first component can be engaged, wherein the guide approach and the recess of the corresponding Ends of the components in question have the same distance so that they define the position of the components to each other in the Can dxenen lengthways.

The frame member is made from the two components in that the abutting surfaces of the flanges of the the two components are glued together and the projection of one component with the surface of the other component lying thereon is glued.

The frame member can be constructed in a simple manner by combining the two components with the flanges and the projection getting produced. On the other hand, one or both of the flanges and / or the protrusion can be used to facilitate assembly be specially designed. Thus, one of the flanges or the projection can be grooved to receive the mating part are provided, or the superposed surfaces of the flanges or the projection can be beveled or m ^ t meshing Teeth or pins and recesses may be formed.

a section 3 which is an adjacent side of the general rectangular cross-section, and a flange H, which in the is substantially perpendicular to an extension 3a of section 3. A projection 5 is provided on the second component, which has a beveled surface 6 and is perpendicular at the junction between the section 3 and the extension 3a, so that when the first component moves in the direction of the arrow against the second component the edge 7 of the first component located between the section 1 and the flange 2 from the beveled one Surface 6 of the projection 5 is detected and guided so that the end 8 of the flanges 2 against the flanges 4 to Impact on it is moved, wherein a box-shaped approach is formed.

In general, the two connections between the two components are the same. This is not essential necessary, but strongly preferred.

The invention can be applied to two different types of training which will now be discussed separately.

In the first type of training, the frame member is off two identical or essentially identical components composed, with each component roughly L-shaped in cross-section and has a small flange extending from the end of one leg of the L substantially at right angles to the other Leg of the L extends away.

In Figure 2, component A is generally L-shaped Cross-section with legs 9a and 10a, the two sides of the hollow

Form cross-section of the frame member. The leg 9a is extended by an extension 9 '. A flange 12a extends substantially at right angles from the end of the extension, and a flange 11a extends substantially at right angles from the end of the leg 10a away from the leg 9a. A projection 13a is formed in one piece with the leg 9a and extends from the leg 9a at the point where the leg 9a ^{merges into the extension 9 1} , the projection 13a lying between the leg 10a and the flanges 12a Projection 13a is provided with a tapered surface 14a. Component B has the same design, the corresponding parts having the same reference numerals but being denoted by socket b instead of a, and the extension of component B being denoted by reference number 9 ". To put together components A and B, so that box-shaped lugs are formed by bringing the end of the flanges 11a of component A to abut flanges 12b of component B and the end of flanges 11b of component B to abut flanges 12a of component A, the components are thus brought together that the projection 13a of the component A grasps the edge lying between the leg 10b and the flange 11b of the component B and the projection 13b of the component B grasps the edge lying between the leg 10a and the flange 11a of the component A, so that the edges be guided in such a way that the * flanges 11a, 11b are moved against the flanges 12b and 12a until they abut them *

In the composition of the components, the

Edge ISa _1, which lies between the flange 11a and the leg ICa of the component A, is captured by the inclined surface IUb of the projection 13b. Also, the edge 15b of the component B is caught by the tapered surface 14a of the projection 13a. As the components approach, ie as the distance between the legs 9a and 9b is shortened, the edges 15a and 15b are guided by the beveled surfaces 14b and 14a, respectively, until the ends 16a and 16b of the flanges 11a and 11b respectively meet the flanges 12b or 12a are in contact. The frame member made from these components has a substantially hollow cross-section and two lugs extending in opposite directions from two opposite sides of the rectangular hollow cross-section of the frame member.

In the other type of training, on which the Invention can apply, is to manufacture the frame member a commonly used U-shaped component.

One form of this second type of training is shown in Fig. in which the parts lying on the left side of the center line X-X are additionally marked with depa letters a and those on the parts lying on the right side additionally with the. Letter b denotes are,.

The generally U-shaped component has a bottom

009886/0717

17a, 17b and legs 18a and 18b, at their ends to the outside facing flanges 19a and 19b are attached. The cover component has a profile that is essentially the same as a Torrn has inverted U. The cover component consists of a base 20a, 20b, extensions 3Ua and 3Ub on each side of the Bottom 20a, 20b and flanges 21a and 21b which extend substantially perpendicular to the extensions. Between the Bottom half 20a and the extension 3Ma and between the bottom half 20b and the extension 3Ub is each a projection ™ 22a bzvj. 22b is provided which has a beveled surface 23a or 23b.

When the U-shaped and the cover components approach one another, ie when the distance between the floor 17a, 17b and the floor 20a, 20b is shortened, the edges 2Ua lying between the legs 18a, 18b and the flanges 19a, 19b of the U-shaped component become or 2Ub of the beveled surfaces 2 3a and 23b of the projections 22a and 22b, respectively, so that the ends 25a λ and 25b of the flanges 19a and ISb are brought to bear against the flanges 21a and 21b, respectively. The two components are glued together with a polyester resin.

It can be seen that in the two described embodiments of the invention, the connection shown in FIG shown shape has

In Fig. H illustrating a box-shaped extension of a frame member, ± §T the flanges 26 of a component with a small downwardly facing lip 27 is provided, on the

009886/0717 bador, q _1NA L

the extension 33 is directed towards the second component. When the first component rests against the flange 28 of the second component, the lip 27 sits in a recess 28a of the flange 28. The projection 29 of the second component is also provided with a beveled surface 30 which, when assembled, the edge 31 of the first component recorded. There is also a head start. Shoulder 32 which supports part of the underside of the flanges 26 in the region of the edge 31 in order to keep the flanges 26 at a distance from the extension 33. The projection also serves to define the flanges 26 between the projection and the flanges 28. The components are glued together with a polyester resin.

In the embodiments described above, the assembled components form a box-shaped extension on the Frame member, i.e. for example in Fig. Ί that the flanges 26 is held at a distance from the extension 33 of the second component.

•. The projections, which detect the edges of the other component may be formed as a extending in the longitudinal direction of the component series of continuous in spaced small projections or as a component located in the longitudinal direction of Kompor extending rib. The height of the protrusion above the extension of the second component

009886/0717

is preferably larger than that of the flanges of the second component against which the end of the flanges of the first component rests. A beveled surface on the projection to capture the edges is preferable, but not absolutely necessary. The angle of inclination of the inclined surface, ie the angle aj in FIG. 4, can be kept relatively small. For example, it can be 3 to 10 to the vertical in relation to the extension 33. Or the beveled surface can have a curvature.

The present invention is particularly applicable to the manufacture of frames, e.g. Window frame, apply that out synthetic polymeric fabrics, e.g. resins reinforced with fibers, exist. A particularly favorable production method consists of compression molding a partially cured mat or plate from with Glass fiber reinforced polyester resin, such as a mat made of the material "FlomatUCe.Wz). During compression molding, the flanges and protrusions are molded integrally with the component.

When molding the components in this manner, it is generally to "facilitate demolding of the molded part appropriate to make the generally rectangular cross-section of the frame member somewhat non-rectangular, i.e. one side of a component to bring something off the vertical with respect to an adjacent side of the component, e.g. by 0.5 to 3 °.

For some purposes it can be advantageous to

if the frame member is asymmetrical, e.g. if a box-shaped approach on one side of the frame member has a different size than a box-shaped approach on the other side of the frame member.

Such an unbalanced frame member is in the transverse. section shown in Fig. 5! which is a cross section through a composite Frame member with bottom extensions 41 and 42 of different Sizes shows.

The window frame components 43,44 shown in Fig. 6 are made by compression molding a partially cured mat of glass fiber reinforced polyester resin, and each component has a flange 45 provided at the end of an extension 46 of a leg 47 and with the Extension includes an angle of 90 °. Another leg 48 is connected to the leg 47 and extends parallel to it in the same direction as the flanges 45. The flange 45 has a longitudinal recess 49 in which, when the components 43, 44 are assembled, a lip 50 of a flange 51 on the front the end of the leg 48 of the other component facing away from the leg 47 can sit, the end of the flanges b1 resting against the side of the recess 49 Shoulder 53 and a ledge 54. In the case of component 44, parts are cut away at one end of the ledge, so that a guide projection 55 is created. A recess 56 shown by dashed lines is in a transverse approach

009886/0717

57 at the corresponding end of the component 43, the removal of the recess 56 from this end of the component 43 equal to the distance of the guide lug 55 from the end of the component 44 is.

So that the ends of the two assembled components 43, 44 are aligned with one another and thus form smooth end surfaces on each end face of the window frame member, the funnel approach bb and the recess 56 are used to fix the components to each other in the longitudinal direction, which is the guide projection 55 and the recess 56 of the corresponding ends of the components 4, 3.44 are equally removed. The guide extension 5 5 and the recess 56 are of the same length in the longitudinal direction of the components, as can be seen from FIG. 6, so that the guide extension 55 can slide straight into the recess 56 when the components are assembled.

It is desirable that the composite window (| frame member plate has end faces so that the frame member with others Frame members that also have smooth front sides are neatly brought together when a whole window frame is designed. -

The components assembled to form a window frame member are preferably bonded with an appropriate adhesive; For example, a polyester resin, along surfaces lying on top of one another, for example between the lips 50 and the recesses 49 and 'on the strips 54 and switches S3, is glued * according to experience

009888/0717

the best bond is achieved when the surfaces lying on top of one another do not rest against one another with an interference fit but are designed in this way sinu that a small space remains between them in which the adhesive is taken up without it being put together squeezed out wind.

The components shown in Figures 7 to 14

A first component 111 has a flange 112 to a section perpendicular 113.steht 'and is formed integral therewith, said portion forming a part of one side of the Hohlquer- W section of the frame member. A second component 114 has a flange 115 which is perpendicular to an extension 116 of the side 117 and is formed in one piece with this extension, the side 117 of the rectangular hollow cross-section being adjacent to the section 113 of the first component 111. A projection 118 is perpendicular to the extension 116 and side 117 and is formed integrally therewith. The projection 118 extends in the longitudinal direction of the second component 114 and supports the first component 111 in the region of the connection point between the flanges 112 and the section 113. The frame member. , 110 is composed by the fact that the

In. 7, the flange 115 has a longitudinal recess 120 on the inside of the upper flange edge. Likewise the projection 118 has a similar recess 121 opposite the recess 120; Theχ recesses 120 and 121 are dimensioned so that that they can receive the flanges 112 and keep them spaced from the extension 116. The recess 121 also serves the ' lateral fixing of the flanges 112 between the projection and the flanges 115.

The approach 110 shown in Fig. 8 also has a "longitudinal recess 120 on the flange 115, the recess 120 in Fig. 7 corresponds. The protrusion 118 has a beveled top edge 122, while the first component 111 has a corresponding beveled edge 123 between the section 113 and the flanges 112 has. The arrangement is such that . when assembling the * two components 111 and in the
