Rim and method for producing a rim
A rim and a method of producing a rim for bicycles and the like includes a rim body and a rim base provided thereon and lateral rim flanks provided with rim flanges. The rim flanges include a fibrous composite material having at least one fiber layer. The rim flanges include inwardly overhanging bulges of squashed fiber layers between which a tire can be accommodated at the rim body.
1. A rim for bicycles comprising: at least a rim body having a rim base and lateral rim flanks provided with rim flanges wherein at least the rim flanges consist at least in part of a fibrous composite material having at least one fiber layer, the rim flanges are formed of parallel fiber layers that are arranged parallel to a radial plane defined by said rim body and include inwardly overhanging bulges between which a tire can be accommodated at the rim body, wherein the layers have ends that are flush with a radially outermost most surface of the overhanging bulges.
2. The rim according to claim 1 , wherein the rim body comprises a rim well which is joined with the rim base through the rim flanks.
3. The rim according to claim 1 , wherein the rim body substantially consists of at least one fibrous composite material.
4. The rim according to claim 1 wherein the rim body consists of at least two rim parts joined to one another.
5. The rim according to claim 4 , wherein the two rim parts are formed substantially symmetrically relative to one another.
6. The rim according to claim 4 , wherein each of the two rim parts form a rim flank with a rim flange and part of the rim base.
7. The rim according to claim 5 , wherein the two rim parts are joined to one another by means of at least one strip of a fibrous composite material.
8. The rim according to claim 1 , wherein the rim body is produced of prepregs at least in part.
9. The rim according to claim 1 , wherein the fiber layers consist of a fiber fabric at least in part.
10. The rim according to claim 1 , wherein the ends of at least some of the fiber layers are provided in the region of the rim flanges.
11. The rim according to claim 1 , wherein the rim body and in particular at least one rim flange consist of at least one fabric hose at least in part.
12. The rim according to claim 1 , wherein the inwardly overhanging bulges are formed from squashed fiber layers.
