Abstract

Profile arrangement for jamming protection and injection mould are provided. A connecting portion of a support profile constructed as a plastic injection moulding and a fastening area of a zonally elastically flexible switching profile are constructed as positively interconnectable plug-in profilings.

Claims

1. A profile arrangement with a support profile in the form of a plastic injection moulding and with an at least zonally, elastically flexible switching profile, which is connected by means of a fastening area to a corresponding connecting portion of the support profile, wherein the connecting portion of the support profile and the fastening area of the switching profile are constructed as positively interconnectable plug-in profilings.

2. The profile arrangement according to claim 1, wherein the switching profile is constructed as a hollow profile without a switching function.

3. The profile arrangement according to claim 1, wherein at least one plug-in profiling of the support profile or switching profile is constructed as a slot open to at least one face and that at least one corresponding plug-in profiling of the switching profile or support profile is constructed as a web arrangement matched to a cross-section of the slot for fitting into one another in the drawing-on direction.

4. The profile arrangement according to claim 3, wherein the web arrangement and the at least one slot are so positively matched to one another that a positive retention at right angles to the sliding direction is ensured.

5. The profile arrangement according to claim 1, wherein the at least one plug-in profiling of the support profile is constructed as a locking recess and the at least one plug-in profiling of the switching profile is constructed as a lug or web-like locking element, which can be plugged into one another at right angles to an opening plane of the locking recess, and that the locking recess and locking element have at least one undercut ensuring a positive retention of the locking element in the locking recess counter to an insertion direction.

6. The profile arrangement according to claim 5, wherein a longitudinal extension of the locking recess is larger than a corresponding extension of the locking element and that the locking recess, considered in the longitudinal extension, has at least two differingly wide opening cross-sections, the differing opening cross-sections being matched to different cross-sectional areas of the locking element, whereof a cross-sectional area at the front in the insertion direction forms an undercut area and a following cross-sectional area forms a sliding area.

7. The profile arrangement according to claim 1, wherein the sliding area or the corresponding opening cross-section vary in cross-section in the sliding direction.

8. The profile arrangement according to claim 1, wherein the connecting portion of the support profile is constructed as an extension of an elastically flexible compensating portion.

9. The profile arrangement according to claim 3, wherein in the longitudinal direction, in the vicinity of a top side, the slot is provided in alternating, pairwise manner with in each case a larger and a smaller opening cross-section and in the vicinity of its underside with crossbars and recesses, the crossbars facing the larger opening cross-sections and the recesses facing the smaller opening cross-sections.

10. An injection mould for the manufacture of a support profile for the profile arrangement according to claim 2, wherein an external geometry of the support profile to be manufactured is made as a mould cavity in at least two mould parts, which are in contact in a common junction plane and have mould cores, which are at least approximately orthogonally positioned with respect to the junction plane and in a functioning position bound a slot of the support profile undercut with respect to the junction plane.

11. An injection mould for the manufacture of a support profile for the profile arrangement according to claim 3, wherein an external geometry of the support profile to be manufactured is made as a mould cavity in at least two mould parts, which are in contact in a common junction plane and have mould cores, which are at least approximately orthogonally positioned with respect to the junction plane and in a functioning position bound a slot of the support profile undercut with respect to the junction plane.

12. The profile arrangement according to claim 2, wherein at least one plug-in profiling of the support profile or switching profile is constructed as a slot open to at least one face and that at least one corresponding plug-in profiling of the switching profile or support profile is constructed as a web arrangement matched to a cross-section of the slot for fitting into one another in the drawing-on direction.

13. The profile arrangement according to claim 12, wherein the web arrangement and the at least one slot are so positively matched to one another that a positive retention at right angles to the sliding direction is ensured.
