Abstract
A wheel rim, made of composite materials, for cycles and the like, is disclosed, comprising at least two adjacent box-like structures presenting a common wall and each constituted by a core of a material of cellular structure and by an envelope of rigid character, based on composite textiles of impregnated and polymerized synthetic fibers closely surrounding the core to which it is bonded, one of the box structures constituting a rim body, while the other defines an outer peripheral rim section intended to mountably recline a tire. The invention is particularly applicable to racing cycle wheels.
Claims7
A wheel rim for cycles and the like comprising:
- a first box structure constituted by a first core formed of cellular material and a rigid first envelope formed of composite textiles of impregnated and polymerized synthetic fibers which houses and is bonded to said first core, said first box structure defining an outer radial peripheral rim section adapted to mountably receive a tire;
- and
- a second box structure constituted by a second core formed of cellular material and a rigid second envelope formed of a composite textile of impregnated and polymerized synthetic fibers which surrounds and is bonded to said second core, said second envelope being integrally formed with said first envelope and including a common wall portion with said first envelope, said second box structure being located radially inward of said first box structure and defining a rim body section.
