Abstract: A crank arm for a bicycle includes a crank arm body having a pedal attachment hole on a first end thereof and a spindle attachment hole on a second end thereof. The crank arm body defines an elongated interior cavity surrounded by a shell, wherein the interior cavity is open to an exterior of the crank arm body. The opening can be used to access the cavity during and after manufacturing. The shape of the cavity may be varied to produce a lightweight yet strong structure. In the method used to form the crank arm body, a mold core formed by a shell containing a sand-like filler material is positioned into a casting mold so that a melt space is formed around the mold core, molten metal is poured into the casting mold, and the molten metal is solidified to form a crank billet. The filler material may be removed through an opening in the crank billet. This may be accomplished by drilling the crank billet to form the pedal attachment hole in a location that communicates with the filler material and then removing filler material through the pedal attachment hole.

Abstract: An object of the present invention is to provide a method for forming a recess portion having an predetermined shape on one side of a metal plate without giving the metal plate any remarkable stress while forming the other side flat, which is suitable for a package for electronic parts such as an integrated circuit, etc. The method according to the present invention is characterized in that a recess portion having an predetermined shape is formed by plastically deforming a metal plate having a predetermined thickness by means of a press, etc. so as to form the recess portion having a depth smaller than the thickness on one side thereof and to form at the same time a protruding portion protruding on the other side of the metal plate. In the steps of plastically deforming the metal plate, metal corresponding to the recess portion is displaced to the protruding portion. Then, the protruding portion on the other side is removed by cutting processing to form the recess portion only on the one side of the metal plate and to form the other side flat.

Abstract: In a method of manufacturing a hollow bicycle crank arm, a sand mold core is positioned into a casting mold so that a melt space is formed around the sand mold core, molten metal is poured into the casting mold, and the molten metal is solidified to form a crank billet. Sand is preferably removed through an opening in the crank billet. This may be accomplished by drilling the crank billet to form the pedal attachment hole in a location that communicates with the sand mold and then removing sand through the pedal attachment hole.

Abstract: A crank arm for a bicycle includes a crank arm body formed of a first material and a core formed of a second material disposed in the crank arm body. The second material has a specific gravity less than a specific gravity of the first material. The second material may be a porous material such as volcanic glass or some other lightweight material. In the method used to form the crank arm body, a core having a specific gravity lower than a specific gravity of the metal forming the outer portions of the crank arm is positioned in a casting mold so that a melt space is formed around the core. Molten metal is poured into the casting mold, and the molten metal is solidified to form a crank billet such that the core is integrally formed with the metal.

Abstract: A forging press having a mechanical load transfer mechanism in the form of a motion and force multiplying lever arrangement and linkage between a press load beam and the press ram so that forces applied to the load beam through the tooling from the ram are transferred to the ram to aid the ram in its downward forging movement. A suitable lost motion linkage is provided which permits the ram to move away from the load beam after the load beam has stopped in its upstroke position to effect the removal of a formed article.

Abstract: A bicycle is provided having a unitary steering tube-crown member and a unitary crank arm-spindle member. A multistage aluminum 3D forging process is used to form the unitary members. This may allow the fabrication of components with substantially hollow interior areas to reduce weight, reduce part count while maintaining high strength and ductility. The multistage 3D forging process provided also allows the combination of multiple components into a single unitary part.
