DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
[0069] FIG. 1 shows a profiled plastic section 1, which comprises a first profiled element 2 depicted above on FIG. 1, and a second profiled element 3 depicted below on FIG. 1. The profiled elements 2, 3 have an oblong shape overall, i.e., they extend significantly more in their longitudinal direction z (which on FIGS. 1 to 4 runs perpendicular to the drawing plane) or depth, usually by a multiple, than in their width x and in their height y. In order to describe the geometry of the profiled plastic section 1, reference will be made below to a Cartesian coordinate system, which consists of a width axis x, a height axis y and a longitudinal axis z, wherein the axes x, y and z are each perpendicular to each other, the width axis x and height axis y lie in the drawing plane, and the longitudinal axis z runs perpendicular to the drawing plane.
[0070] The first profiled element 2 comprises a first hook 4, a first transverse web 5, a second transverse web 6 along with a groove 8, a trough-shaped groove 8 in the exemplary embodiment shown. The second profiled element 2 comprises a second hook 9, a third transverse web 10, a fourth transverse web 11 along with a sliding lug 12, a rounded sliding lug 12 in the exemplary embodiment shown. The hooks 4, 9 and transverse webs 5, 6 and 10, 11 stick out perpendicularly from facing inner surfaces of the profiled elements 2, 3, and essentially run parallel to the height axis y when the profiled plastic section 1 is assembled.
[0071] For example, the profiled plastic section 1 or its profiled elements 2, 3 can be made out of the material TECATHERM66 GF of the applicant, a plastic that is based on a black polyamide and comprises 25% w/w glass fibers. This material is characterized in particular by its good suitability for the intended application. It is further perfectly suitable for manufacturing hollow chamber profiled sections with thin walls, for powder coatings and anodizing in a composite.
[0072] The groove 8 and sliding lug 12 together comprise a sliding arrangement in the form of a loose hinge or a loose swivel joint 13 with a rotational axis 14. As depicted on FIGS. 1 to 4, the first profiled element 2 and second profiled element 3 can be turned or tilted relative to each other around the rotational axis 14 of the swivel joint 13. In the exemplary embodiment shown, the rotational axis 14 runs parallel to the longitudinal axis z. An angular range by which the first profiled element 2 and second profiled element 3 can here be turned relative to each other is limited, wherein FIG. 1 depicts a maximally open twisting or tilting position of the profiled elements 2, 3 relative to each other, while FIGS. 3 and 4 depict a maximally closed twisting position of the profiled elements 2 relative to each other.
[0073] In the twisting position of the profiled elements 2, 3 relative to each other shown on FIG. 1, a first stop surface 15 of the groove 8 abuts against a corresponding second stop surface 16 of the second profiled element 3. In this position, the first profiled element 2 and second profiled element 3 form an acute angle relative to each other, wherein the first hook 4 does not touch the second hook 9, the first transverse web 5 does not touch the second transverse web 10, and the third transverse web 6 does not touch the fourth transverse web 11.
[0074] FIG. 2 shows the first profiled element 2 and second profiled element 3 in another twisting position relative to each other, wherein the first hook 4 touches the second hook 9, the first transverse web 5 touches the second transverse web 10, and the third transverse web 6 touches the fourth transverse web 11. The position of the profiled elements 2, 3 relative to each other shown on FIG. 2 was achieved by twisting the profiled elements 2, 3 around the rotational axis 14 out of the relative position depicted on FIG. 1 toward each other. In this case, the first profiled element 2 can be twisted counterclockwise in relation to the illustration on FIGS. 1 to 4 (spinning arrow 7, FIG. 2), and/or the second profiled element 3 can be twisted clockwise in relation to the illustration on FIGS. 1 to 4.
[0075] As evident from FIGS. 1 to 4, the hooks 4, 9 and transverse webs 5, 10 and 6, 11 each have a chamfer. The chamfers are arranged and oriented in such a way as to touch each other in the rotational position of the first profiled element 2 and second profiled element 3 relative to each other depicted on FIG. 2. When the profiled elements 2, 3 are further twisted relative to each other, the chamfers act as a guide, so as to connect the first profiled element 2 with the second profiled element 3 via a form-fitting connection (FIGS. 3 and 4). For illustrative purposes, each of the chamfers is provided with a reference number 17 to 22 on FIG. 1, wherein in the position depicted on FIG. 2, a first chamfer 17 of the first hook 4 abuts against a second chamfer 18 of the second hook 9, a third chamfer 19 of the first transverse web 5 abuts against a fourth chamfer 20 of the second transverse web 10, and wherein a fifth chamfer 21 of the third transverse web 6 abuts against a sixth chamfer 22 of the fourth transverse web 11.
[0076] FIG. 3 shows the profiled elements 2, 3 in a third twisting position relative to each other, wherein the first hook 4 is latched into the second hook 9. Proceeding from the position shown on FIG. 2, the profiled elements 2, 3 were twisted further around the rotational axis 14 relative to each other, so that a first hook head 23 of the first hook 4 and a second hook head 24 of the second hook 9 have moved past each other exposed to an elastic deformation. The hook head 23 of the first hook 4 points to the left according to FIGS. 3 and 4, and the hook head 24 of the second hook 9 points to the right according to FIGS. 3 and 4. Similarly, the first transverse web 5 and second transverse web 10 along with the third transverse web 6 and fourth transverse web 11 have moved past each other a bit while exposed to an elastic deformation, and now abut against each other over a large surface, as shown on FIGS. 3 and 4. The transverse webs 5, 10 and 6, 11 here span the hooks 4, 9 in their intermeshing position, and ensure a tractive connection and a form-fitting connection between the first profiled element 2 and second profiled element 3.
[0077] The form-fitting connection produced by the hooks 4, 9 and transverse webs 6, 10 and 6, 11 acts parallel to the width axis x, and allows the assembled profiled plastic section 1 to be able to absorb tensile and compressive forces parallel to the width axis x. Furthermore, the hooks 4, 9 and the pivot joint 13 or its groove 8 and sliding lug 12 produce another form-fitting connection, which acts parallel to the height direction y, and allows the assembled profiled plastic section 1 to be able to absorb tensile and compressive forces parallel to the height axis y.
[0078] The tractive connection generated by the hooks 4, 9 and transverse webs 5, 10 and 6, 11 is produced by spacing the hooks 4, 9 and transverse webs 5, 10 apart from each otherin undersized fashion, so to speakin the assembled state of the profiled plastic section 1 in such a way that they tension each other. In other words, the transverse webs 5, 10 serve as a tensioning counter bearing for the hooks 4, 9 and vice versa. In particular, the tractive connection acts parallel to the height axis y as a frictional connection, so that the profiled elements 2, 3 are impeded from once again moving out of their twisting position relative to each other shown on FIGS. 3 and 4.
[0079] In order to generate the elastic deformation of hooks 4, 9 and transverse webs 5, 6 and 10, 11, an elevated expenditure of force or an elevated torque is required, for example which can be provided by exerting a compressive force F.sub.1, e.g., which acts perpendicular to an outer surface 43 of the first profiled element 2 and, according to FIG. 3, roughly parallel to the height axis y, on the first profiled element 2 at position 25, wherein the second profiled element 3 is immobile or held in place, and thus serves as a counter bearing for the first profiled element 2. Position 25 is located in an end area 26 of the first profiled element 2 lying opposite the groove 8, which results in the formation of an especially long lever arm, which can provide an especially high torque for generating the elastic deformation of the hooks 4, 9 and transverse webs 5, 10 and 6, 11.
[0080] In the position shown on FIGS. 3 and 4, the first profiled element 2 and second profiled element 3 are thus joined together via a form-fitting connection. As a consequence, the profiled plastic section 1 is assembled. In particular, the form-fitting connection can be detachable or reversible in design, i.e., the first profiled element 2 and second profiled element 3 can be nondestructively detached from each other again. This can be done by separating the hooks 4 and 9 from each other, e.g., by now exerting a tensile force F.sub.2 instead of a compressive force on the first profiled element 2 at position 23, wherein the second profiled element 3 is immobile or held in place, and thus serves as a counter bearing. The tensile force F.sub.2 allows the hook heads 23, 24 and transverse webs 5, 10 and 6, 11 to move past each other while exposed to elastic deformation, and to be brought back into the position shown on FIGS. 1 and 2. Furthermore, the profiled elements 2 and 3 can also be moved in opposite directions relative to the longitudinal axis z, so that they are pulled apart in the longitudinal direction z.
[0081] Furthermore, the first profiled element 2 forms a first one-part connecting strip 27 on its longitudinal edge shown on the right of FIGS. 1 to 4, and the second profiled element 3 forms a second one-part connecting strip 28 on its longitudinal edge shown on the left of FIGS. 1 to 4. The one-part connecting strips 27, 28 can be used to introduce the assembled profiled plastic sections 1 into corresponding receptacles of profiled metal sections 29, 30 (FIG. 4), e.g., comprised of aluminum, and there be held in a shear-resistant manner, e.g., by means of a frictional, tractive or form-fitting connection. In this conjunction, FIG. 4 shows a first metal component in the form of a first profiled metal section 29 (on the left), and a second metal component in the form of a second profiled metal section 30 (on the right). The corresponding receptacles of the profiled metal sections 29, 30 correspond with the essentially trapezoidal cross sections of the connecting strips 27, 28. The first profiled metal section 29 is connected with the first profiled element 2 of the profiled plastic section 1 in a shear-resistant manner, and the second metal component 30 is connected with the second profiled element 3 of the profiled plastic section 1 in a shear-resistant manner, thereby forming a metal/plastic composite profiled section 31. The metal/plastic composite profiled section 31 can be a constituent of a frame (not shown) for a window, a door or a faade element.
[0082] In the exemplary embodiment shown on FIGS. 1 to 4, the connecting strips 27, 28 have optional frontal recesses, into which sealing wires 32, 33 are inserted. The shear resistance of the composite between the profiled plastic section 1 and profiled metal sections 29, 30 can thus be additionally ensured by activating the sealing wires 32, 33. For example, an activation temperature or melting point of the sealing wires 32, 33 can lie with a range of approx. 95 to 100 C. Furthermore, the surface 34 of the second profiled element 3 facing away from the first profiled element 2 has two parallel running and spaced apart flags 35, 36, which in particular contribute to reducing convective heat transfers within the metal/plastic composite profiled section 31.
[0083] In the position shown on FIGS. 3 and 4, the first profiled element 2 and second profiled element 3 overlap over a large area. The first profiled element 2 has an essentially L-shaped cross section, and the second profiled element 3 has an elbowed design. The geometries and dimensions of the profiled elements 2, 3 are here tailored to each other in such a way that the profiled plastic section 1 essentially has a box shape with several hollow chambers 37 to 40 in an assembled state. The box is closed at a first end relative to the width axis x by the groove 8 and sliding lug 12. At a second end lying opposite the first end relative to the width axis x, the box is closed by a first contact surface 41 of the first profiled element 2 and a second contact surface 42 of the second profiled element 3 corresponding to the first contact surface 41.
[0084] The box-shaped structure of the profiled plastic section 2 gives it a high stiffness and stability. Furthermore, insulating foams can be introduced into the hollow chambers 37 to 40, so as to enable an especially low heat transition coefficient U.sub.r of the metal/plastic composite profiled section 31. As an alternative to introducing insulating foams, an infrared radiation-reflecting, so-called low-E film can be applied to the side walls of the transverse webs or hook elements in particular in the area of the hollow chambers 37 to 40, e.g., an Insulbar LEF film of the applicant, wherein low-e stands for an especially low degree of emissivity .
[0085] As a result of the form-fitting connection between the first profiled element 2 and second profiled element 3, the profiled elements 2, 3 cannot be moved relative to each other parallel to the width axis x and parallel to the height axis y. In particular forces acting parallel to the width axis x on the first profiled element 2 and second profiled element 3 can thus be absorbed to an especially high extent by the profiled plastic section 1. The cohesion of the profiled plastic section 1 is further increased and its stability elevated by virtue of the fact that the profiled elements overlap over a large-surface, are hooked together by the hooks 4, 9 and tensioned by the transverse webs 5, 10 and 6, 11. As a consequence, in particular even forces acting parallel to the height taxis y on the first profiled element 2 and the second profiled element 3 can be absorbed to an especially high extent by the profiled plastic section 1.
[0086] By contrast, the profiled elements 2, 3 can move parallel to the longitudinal axis z relative to each other. In particular, the contact surfaces 41, 42, hooks 4, 9, transverse webs 5, 10 and 6, 11 and groove 8 and sliding lug 12 of the profiled elements 2, 3 can slide parallel to the longitudinal axis along each other. As a result, a relative movement of the profiled elements 2, 3 in the longitudinal direction can offset various longitudinal expansions of the first profiled element 2 and second profiled element 3 or longitudinal expansions of the profiled metal sections 29, 30 connected with the profiled elements 2, 3 in a shear-resistant manner.
[0087] FIGS. 5 and 6 each show another profiled plastic section 1, which is similar to the profiled plastic section 1 according to FIGS. 1 to 4, and differs with respect to the configuration of the hooks 4, 9 and transverse webs 5, 10. To avoid repetition, only the differences from the exemplary embodiment according to FIGS. 1 to 4 will be discussed below. The profiled plastic section 1 according to FIG. 5 has only two transverse webs 5, 10 instead of four transverse websas shown on FIGS. 1 to 4. The hooks 4, 9 are here arranged on the same side as depicted on FIGS. 1 to 4, but can be thicker in design, so as to enable an optimized transverse force transmission. The first hook head 23 of the first hook 4 points to the right according to FIG. 5, and the second hook head 24 of the second hook 9 points to the left according to FIG. 5. Due to the arrangement of the hook heads 23 and 24, the first hook 4, second hook 9, groove 8 and joint pin 12 can be used to produce a form-fitting connection between the first profiled element 2 and second profiled element 3, which acts parallel to the width axis x and parallel to the height axis y, as described in conjunction with FIGS. 1 to 4. Alternatively, a way to establish a linear connection between the profiled elements 2 and 3 can further be provided in place of the groove 8 and joint pin 12.
[0088] As described in conjunction with FIGS. 1 to 4, the transverse webs 5, 10 produce a tractive connection between the first profiled element 2 and second profiled element 3. Only the hooks 4, 9 and joint 13 are required to ensure a reliable cohesion of the profiled element 1 or its first profiled element 2 and second profiled element 3.
[0089] As depicted on FIG. 6, the transverse webs 5, 10 can be omitted for generating the form-fitting connection. By omitting the transverse webs 6, 11 (see FIGS. 1 to 4), only three hollow chambers 37, 38 and 39 are formed (FIG. 5) instead of four hollow chambers 37 to 40 in the assembled state of the profiled plastic section 1. By further omitting the transverse webs 5, 10 (see FIGS. 1 to 4), only two hollow chambers 37, 39 are formed (FIG. 6) instead of four hollow chambers 37 to 40 in the assembled state of the profiled plastic section 1.
[0090] FIGS. 7 to 10 show another profiled plastic section 1 for a metal/plastic composite profiled section. The profiled plastic section 1 comprises a first profiled element 2 and a second profiled element 3, wherein the first profiled element 2 and second profiled element 3 together form a latching mechanism 44 (see in particular FIGS. 8 to 10), which can be used to produce a form-fitting connection between the first profiled element 2 and second profiled element 3. The first profiled element 2 and second profiled element 3 overlap over a large surface in their width direction x if the form-fitting connection has been produced between the first profiled element 2 and second profiled element 3 as depicted on FIG. 7, wherein the form-fitting connection between the first profiled element 2 and second profiled element 3 can be produced by moving the profiled elements 2, 3 in a height direction y of the profiled plastic section 1. The form-fitting connection between the first profiled element 2 and second profiled element 3 is here configured in such a way as to permit a movement by the first profiled element 2 and second profiled element 3 in a longitudinal direction z of the profiled plastic section 1 if a first metal component (see FIG. 4) has been connected with the first profiled element 2 in a shear-resistant manner, and a second metal component (see FIG. 4) has been connected with the second profiled element 3 in a shear-resistant manner.
[0091] FIG. 7 shows that the profiled elements 2, 3 each have a mutually corresponding cross section for their connection, the progression of which in the width direction x equates to a square wave voltage. A plurality of identical projections 45 of the first profiled element 2 that run parallel to each other and are spaced apart from each other here engage into corresponding recesses 46 of the second profiled element 3, and a plurality of identical projections 47 of the second profiled element 3 that run parallel relative to each other and are spaced apart from each other engage into corresponding recesses 48 of the first profiled element 2.
[0092] FIG. 8 shows that flanks of the projections 45/47 of the first/second profiled element 2/3 that run in the height direction y can each have a contour resembling a pine cone with a zigzag progression. The contours are shaped and oriented relative to each other in such a way that the projections 45 and 47 can hook into each other, thereby enabling an especially secure hold of the profiled elements 2, 3 with each other in the height direction y.
[0093] FIG. 9 shows that a respective hook element 50 resembling an arrow tip can be formed at the ends of the projections 45/47 of the first/second profiled element 2/3 that are distal relative to the height direction y. The hook elements 50 are shaped or oriented relative to each other in such a way that the projections 45 and 47 can hook into each other, thereby enabling an especially secure hold of the profiled elements 2, 3 with each other in the height direction y.
[0094] FIG. 10 shows that a respective ball element 51 can be formed at the ends of the projections 45/47 of the first/second profiled element 2/3 that are distal relative to the height direction y. The ball elements 51 are shaped or oriented relative to each other in such a way that the projections 45 and 47 can hook into each other, thereby enabling an especially secure hold of the profiled elements 2, 3 with each other in the height direction y.
[0095] FIG. 11 shows another profiled plastic section 1 that is very similar to the profiled plastic section 1 according to FIG. 1, and is characterized by its rearward-reinforced areas of the transverse webs 5, 10 and 6, 11. In this conjunction, rearward is to be understood as the respective side of the transverse webs 5 and 6 that does not come into contact with a respective opposing transverse web 6 and 11 and vice versa. The surfaces of the transverse webs 5, 10 and 6, 11 that do come into contact with each other can further have a surface contour as illustrated and described in conjunction with FIG. 8, wherein a surface structure can have an especially fine configuration. This makes it possible to achieve an especially strong cohesion for the profiled elements 2 and 3 in the height direction y of the profiled plastic section.
[0096] FIGS. 12 and 13 show additional profiled plastic sections 1, which are similar to the profiled plastic section 1 according to FIG. 1. However, the exemplary embodiments according to FIGS. 12 and 13 have bifunctional latching and sliding elements, which consist of several hook-like elements or transverse webs 5, 10, 6 and 11. The latter are additionally secured by a hook pair 4, 9. According to the exemplary embodiments on FIGS. 12 and 13, the respective first hook head 23 of the first hook 4 is oriented toward the right, and the second hook head 24 of the second hook 9 is oriented toward the left. As evident from FIG. 14, the hook heads 23 and 24 of the hooks 4, 9 can have an undercut design. The undercut allows an especially strong intermeshing of hook heads 23 and 24, and thus an especially strong cohesion for the profiled elements 2 and 3 in the height direction y of the assembled profiled plastic section 1. The transverse webs 5, 10 and 6, 11 envelop the hooks 4, 9 on either side, and are shaped and arranged relative to each other in such a way as to fix the hooks 4, 9 into their reciprocally hooked position shown on FIGS. 12 and 13, and counteract any drifting apart of the profiled elements 2 and 3 in the height direction y.
[0097] In the exemplary embodiments according to FIGS. 12 and 13, a first hollow chamber 52 is formed between the transverse webs 5, 10 and hooks 4, 9, and a second hollow chamber 53 is formed between the hooks 4, 9 and transverse webs 6, 11. This is also the case in the exemplary embodiments of profiled plastic sections 1 according to FIGS. 15 and 16, which each are similar to the exemplary embodiment according to FIG. 13. The exemplary embodiments according to FIGS. 15 and 16 are characterized in that the first profiled element 2 forms an additional hollow chamber 54 (FIG. 15) or two additional hollow chambers 54 and 55 (FIG. 16) in an end area of the profiled plastic section 1 shown on the right of FIGS. 15 and 16. The hooks 4, 9 according to FIGS. 15 and 16 can also be undercut in design, as also illustrated on FIG. 14. Alternatively, the hooks 4, 9 shown on FIGS. 15 and 16 or their hook ends can also be oriented as depicted on FIGS. 12 to 14.
[0098] FIG. 17 shows another exemplary embodiment of a profiled plastic section 1, which is similar to the profiled plastic section 1 according to FIG. 1. According to FIG. 17, the profiled plastic section 1 has three hook pairs, which each comprise a first hook 4 and a second hook 9, and are arranged next to each other and spaced apart relative to each other in the width direction x of the profiled plastic section 1. The two right hook pairs on FIG. 17 here replace the transverse webs 5, 10 and 6, 11 according to the exemplary embodiment on FIG. 1, and ensure an especially secure cohesion of the profiled elements 2, 3 in the height direction y of the profiled plastic section 1. The three hook pairs further act to stabilize the profiled plastic section 1 in its central area, and to prevent a bulging of the profiled plastic section 1 in the central area. In addition, the groove 8 and sliding lug 12 are mirror-inverted by comparison to the exemplary embodiment according to FIG. 1. This arrangement enables an especially high load transfer in the pulling direction.
[0099] FIG. 18 shows another exemplary embodiment of a profiled plastic section 1, which differs from the profiled plastic section according to FIG. 17 in that the groove 8 and sliding lug 12 are oriented as in the exemplary embodiment according to FIG. 1. The hooks 4, 9 according to FIGS. 17 and 18 can also be undercut in design, as illustrated on FIG. 14.
[0100] FIG. 19a shows isolated profiled elements 2 and 3 that are present on FIG. 19b as an assembled profiled plastic section 1. For connection purposes, the profiled elements 2 and 3 each have cross sections corresponding to each other. This diagram presents a strongly exaggerated wall thickness change in the width direction x, which can be configured in such a way as to achieve an ideal ratio between force transfer, heat transfer and material usage. A sliding arrangement or sliding rail 13 is assembled by introducing a sliding lug 12 into a groove 8. Among other things, this is also simplified through a slight elastic deformation of the profiled elements 2 and 3. The height of the sliding lug 12 and depth of the corresponding groove 8 can be adjusted accordingly to the intended purpose. After the sliding lug 12 has been inserted into the groove 8, the profiled elements 2 and 3 can be folded together, wherein two transverse webs 5 and 10 first overlap, after which a latching connection formed by two hooks 4 and 9 engages, and connects the profiled section 1 in a form-fitting manner in the transverse directions x, y. In other words, the profiled elements 2 and 3 can no longer independently move opposite each other within the cross sectional plane x-y. At the same time, however, the profiled elements 2 and 3 can independently move opposite each other in the direction of the z-axis, which runs orthogonally to the x-y plane. This is referred to as a shear-free connection.
[0101] As the case with FIG. 19a, FIG. 20a shows isolated profiled elements 2 and 3, which on FIG. 20b are present as an assembled profiled plastic section 1. For connection purposes, the profiled elements 2 and 3 each have cross sections corresponding to each other. This diagram presents a strongly exaggerated wall thickness change in the width direction (x-axis), which can be configured in such a way as to achieve an ideal ratio between force transfer, heat transfer and material usage. A sliding arrangement or sliding rail 13 is assembled by introducing a pointed sliding lug 12 of the first profiled element 2 into a matching groove 8 of the second profiled element 3. Assembly takes place in a manner similar to the one described in conjunction with FIG. 19. Also shown here are corresponding transverse webs 5 and 10, along with a latching connection formed by two hooks 4 and 9. The function of the profiled plastic section 1 on FIG. 20b largely corresponds to the function of the profiled plastic section 1 according to FIG. 19b.
[0102] FIG. 21a shows three isolated profiled elements 2, 3 and 3a, which are present on FIG. 21b as an assembled, complex profiled plastic section 1. What makes this example special is the higher configuration of the profiled plastic section 1 in the y-direction, wherein the assembled profiled plastic section 1 can assume the function of two individual profiled plastic sections, e.g., the functions of the profiled plastic sections 1 according to FIGS. 19 and 20 in a plastic/metal composite profiled section (not shown on FIG. 1, see here the plastic/metal composite profiled sections 31 and 60 from FIG. 4 or 25), and enables additional static advantages owing to braces 295a and 295b. For connection purposes, the profiled elements 2, 3 and 3a each have cross sections corresponding to each other. While this diagram presents a strongly exaggerated wall thickness change in the width direction x known from FIGS. 19 and 20, the latter is not absolutely necessary. The profiled plastic section 1 is assembled in a manner similar to the way already described in conjunction with FIGS. 19 and 20. Also shown here are: corresponding transverse webs 5 and 10, two latching connections each formed by two hooks 4 and 9, and in this example, two differently designed sliding arrangements or sliding rails 13a and 13b, wherein the first sliding arrangement 13a is formed by a sliding lug 12a of the second profiled element 3 and a corresponding groove 8a in the first profiled element 2.
[0103] The second profiled element 3 further has a wider sliding lug 12b, which is angularly arranged, runs in the height direction y, and can be inserted into another corresponding groove 8b of the third profiled element 3b (FIG. 21b). The function of the profiled plastic section 1 on FIG. 21b expands the function of the simple profiled plastic sections, for example as depicted on FIG. 19b or 20b. The profiled plastic section 1 thus becomes easier to handle than two individual profiled plastic sections (e.g., the profiled plastic sections 1 according to FIGS. 19 and 20), and the profile statics are likewise advantageous for mechanically demanding end applications. The second profiled element 2 has two connecting strips 290a and 290b for producing a respective connection with a second metal component (not shown) that is shear-free in the z-direction. The first profiled element 2 and third profiled element 3b each have a connecting strip 290c or 290d, which each can separately be connected shear-free in the z-direction with a first metal component (not shown). The second profiled element 3 is connected shear-free in the z-direction with the first profiled element 2 and with the third profiled element 3a, i.e., the second profiled element 3 can be moved in the longitudinal direction z of the profiled plastic section 1 relative to the first profiled element 2 and relative to the third profiled element 3a if the profiled elements 2, 3 and 3a are separately connected shear-free in the z-direction with profiled metal sections.
[0104] The profiled elements 2 and 3 according to FIG. 22aeach turned by 90correspond to the profiled elements 2 and 3 according to FIG. 19a. FIGS. 22b to 22e show alternative shapes and optional arrangements for the sliding lug 12 and groove 8 of the respective sliding arrangement 13. FIG. 22b shows a sliding lug 12 of the first profiled element 2 running in the y-direction, which can be introduced into a corresponding groove 8 of the second profiled element 3. FIG. 22c shows a sliding lug 12 of the second profiled element 3 that is tapered in the width direction x, wherein the sliding lug 12 can be introduced into a corresponding groove 8 of the first profiled element 2. FIG. 22d shows a sliding lug 12 of the first profiled element 2 having a rounded distal end, wherein the sliding lug 12 can be introduced into a corresponding groove 8 of the second profiled element 3. FIG. 22e further shows a wedge-shaped sliding lug 12 of the first profiled element 3 that is tapered in the width direction x, wherein the sliding lug 12 can be introduced into a corresponding groove 8 of the second profiled element 3.
[0105] FIG. 23a and FIG. 23b show a variation of the profiled plastic section 1 according to FIG. 21a and FIG. 21b, wherein the second profiled element 3 is here designed with just one connecting strip 390b. In addition, the second profiled element 2 has two transverse webs 5, and the two other profiled elements 2, 3a each have two corresponding transverse webs 10, wherein the especially strongly overlapping, intermeshing transverse webs 5 and 10 in the interlocked profiled plastic section 1 can absorb both tensile and compressive forces in the width direction x. A total of three connecting strips 390a, 390b and 390c are present in the profiled plastic section 1, wherein the profiled plastic section 1 itself comprises three profiled elements 2, 3 and 3a, and wherein the outer profiled elements 2 and 3a are identical. FIG. 23a depicts loose profiled elements 2, 3 and 3a, i.e., the first profiled element 2, the second profiled element 3 and the third profiled element 3a. FIG. 23b depicts the interlocked state, meaning the assembled, symmetrical profiled plastic section 1 (symmetry axis C2, shown in the middle of the profiled plastic section 1). Likewise shown are corresponding hook pairs 4 and 9 and two sliding arrangements 13, each formed by a sliding lug 12 on the second profiled element 2 with matching groove 8 on the respective accompanying profiled elements 2 and 3a.
[0106] FIG. 24 illustrates the large-surface overlap L.sub.D of the profiled elements 2 and 3 from FIG. 19 that runs in the width direction (x-axis). For further clarification, the profiled plastic section 1 according to FIG. 19 is to this end shown with the two profiled elements 2 and 3 displaced against each other in the y-direction. The entire width L.sub.ges of the profiled plastic section 1 here consists of the widths L.sub.1 and L.sub.2 of the two profiled elements 2 and 3 minus the overlap L.sub.D. Since the overlap does not comprise the area of the connecting elements LE.sub.1 and LE.sub.2, the width of the profiled plastic section L.sub.ges can also be expressed as follows:
L.sub.ges=LE.sub.1+LE.sub.2+L.sub.D.
[0107] FIG. 25 shows two identical profiled plastic sections 1 arranged one over the other in the height direction y, which each involve an exemplary embodiment of a profiled plastic section 1 according to the invention. The profiled plastic sections 1 are arranged so as to mirror each other relative to the width direction x and height direction y. Similarly to the manner shown on FIGS. 1 to 4, for example, the profiled plastic sections 1 each have two connecting strips 27 and 28, which are accommodated in corresponding receptacles 56 and 57 of a first profiled metal section 58 shown on the left of FIG. 25 and a second profiled metal section 59 shown on the right of FIG. 25, in particular in a shear-resistant manner. The profiled metal sections 58 and 59 can be common parts, which can be made out of aluminum. The profiled plastic sections 1 and profiled metal sections 58, 59 together form a metal/plastic composite profiled section 60. The metal/plastic composite profiled section 60 can be a constituent of a frame (not shown) for a window, door or faade element.
