Abstract

A profiled outer sole for shoes, especially sport shoes, made in a mold and consisting of rubber or other material having rubber-elastic properties, which is provided with profiled projections laterally delimiting the tread surface of the outer sole; the profiled projections, in turn, are provided with groove-shaped slots extending obliquely to the respective tangential plane tangential to the outer boundary surfaces of the individual profiled projections within the bisecting plane thereof.

Claims

A profiled outer sole for shoes made of a material having rubber-elastic properties, and provided with profiled projection means arranged along lateral sole edges, characterized in that the profiled projection means laterally delimit a tread surface of the outer sole, each of the profiled projection means are provided with at least two V-shaped slots opening in a direction toward a longitudinal axis of the sole and extending obliquely to a tangential plane at outer boundary surfaces of the individual profiled projection means in a bisecting plane thereof, said at least two V-shaped slots are nested one within the other.

2. An outer sole according to claim 1, characterized in that the outer sole is a molded sole.

3. An outer sole according to claim 2, characterized in that the V-shaped slots are arranged at least approximately symmetrically to the respective bisecting plane of the individual profiled projection means extending substantially perpendicularly to a longitudinal axis of the sole.

4. An outer sole according to claim 1, characterized in that the outer sole is for sports shoes.

5. An outer sole according to claim 1, characterized in that the outer sole is made from a material selected from the group consisting of rubber and synthetic resinous materials.

6. An outer sole according to claim 1, characterized in that the profiled projection means are approximately block-shaped.

7. An outer sole according to claim 1, characterized in that the V-shaped slots are arranged at least approximately symmetrically to the respective bisecting plane of the individual profiled projection means extending substantially perpendicularly to the sole longitudinal axis.

8. An outer sole according to claim 7, characterized in that the V-shaped slots subtend an angle of about 20°

to about 40°

with the tangential plane at the outer boundary surface of the respective profiled projection means.

9. An outer sole according to claim 8, characterized in that the V-shaped slots have a width of about 1 to 2 mm. and a depth which corresponds to approximately half a height of the profiled projection means.

10. An outer sole according to claim 9, characterized in that a mutual spacing of adjacent V-shaped slots corresponds approximately to a width of such a slot.

11. An outer sole according to claim 8, characterized in that the V-shaped slots subtend an angle of about 30°

with a tangential plane at the outer boundary surface of the respective profiled projection means.

12. An outer sole according to claim 8, characterized in that the V-shaped slots subtend an angle of about 20°

to about 40°

with the tangential plane at the outer boundary surface of the respective profiled projection means.

13. An outer sole according to claim 8, characterized in that the V-shaped slots have a width of about 1 to 2 mm. and a depth which corresponds to approximately half a height of the profiled projection means.

14. An outer sole according to claim 8, characterized in that a mutual spacing of adjacent groove-shaped slots corresponds approximately to a width of such a slot.

15. An outer sole according to claim 8, characterized in that rows of profiled projection means are disposed at both lateral sole edges and are connected with each other by segmentally-shaped profiled projections.

16. An outer sole according to claim 15, characterized in that the segmentally shaped profiled projections are provided with groove-shaped slots extending at least approximately perpendicularly to the sole longitudinal axis.

17. An outer sole according to claim 1, characterized in that the profiled projection means delimiting a front of the sole and associated segmentally shaped profiled projections surround inner profiled projections with smaller effective tread surface than a surface of the profiled projection means surrounding the same.

18. An outer sole according to claim 17, characterized in that the inner profiled projections are knub shaped.

19. An outer sole according to claim 1, characterized in that the segmentally shaped profiled projection means delimiting a rear of the sole and associated segmentally shaped profiled projections surround profile projections with smaller effective tread surface than a surface of the profiled projection means surrounding the same.

20. An outer sole according to claim 19, characterized in that the inner profiled projections are knub-shaped.

21. An outer sole according to claim 1, characterized in that edges of the tread surface of the outer sole extend essentially parallel to the sole longitudinal axis and are formed by extensions which project with respect to the lateral surfaces of the outer sole.

22. An outer sole according to claim 21, characterized in that the lateral extensions extend beyond longitudinal sides of the sole with the exception of a strongly rounded-off forward and rear outer sole ends.

23. An outer sole according to claim 22, characterized in that the lateral extensions are constructed as shoulders rounded-off at the tread surface of the outer sole.

24. An outer sole according to claim 23, characterized in that the shoulders terminate at least within an area of a forward end of the sole in a drawn-up shell edge of an outer sole constructed as shell sole.
