发明名称 Bicycle drop-out and method of attachment.
摘要 <p>A metal drop-out (30) is attached to a receiving tube of a bicycle frame. The drop-out includes a slotted axle-retaining section (32) and a mounting section which is of one-piece integral construction with the axle-retaining section. The mounting section (36) is bent relative to the axle-retaining (32) section along a transverse bend region (38) by an angle by about 10 to 90 degrees. An end edge (42) of the mounting section is machined to a generally cylindrical configuration defining a first longitudinal axis (L). The machined end edge of the mounting section is inserted into an end (48) of a receiving tube (46) and is welded thereto. &lt;IMAGE&gt;</p>
