20080231106 | Bicycle wheel rim - A bicycle wheel rim includes an annular rim body having a rim axis, and including left and right annular side walls, a pair of annular oblique walls, an annular base wall, left and right annular connecting walls, and a pair of annular tire-retaining ribs. Each of the left and right annular side walls has a radial outer edge. Each of the oblique walls extends obliquely from a respective one of the side walls toward the other one of the side walls. The base wall interconnects the oblique walls and has a radial outer side. Each of the left and right annular connecting walls extends from the base wall to connect to a respective one of the side walls. A radial distance between the radial outer side of the base wall and the radial outer edges,of the side walls ranges from 8.5 millimeters to 12.5 millimeters. | 09-25-2008 |
20080277998 | Wheel rim - A wheel rim includes an annular rim body having a horizontally disposed rim axis. The rim body includes an annular base wall, and a pair of opposite annular side walls. The annular base wall is formed with a plurality of spoke fastening holes spaced apart from each other, and has two opposite lateral edges. The annular side walls extend radially, outwardly and respectively from the lateral edges of the annular base wall. Each of the annular side walls includes a hollow segment that defines an annular hole. The hollow segment has an inner wall portion disposed at an inner side of the annular hole and facing the other one of the annular side walls, and an outer wall portion connected to the inner wall portion and disposed at an outer side of the annular hole opposite to the inner side of the annular hole. | 11-13-2008 |
20090195055 | Wheel Rim - A wheel rim includes an annular rim body that has an annular base wall, a pair of annular side walls, and a stop unit. The annular side walls extend respectively from lateral edges of the annular base wall. Each annular side wall includes a hollow segment and a connecting segment that interconnects the hollow segment and the annular base wall. Each hollow segment has an inner wall portion, an outer wall portion, and a tire bead retaining part projecting from the inner wall portion toward the other one of the annular side walls. Each inner wall portion is adapted for contacting a respective one of tire beads of a tire and cooperates with the stop unit and the respective tire bead retaining part to retain the respective tire bead. | 08-06-2009 |
20100270852 | Wheel Rim - A wheel rim includes an annular rim body having a horizontally disposed rim axis. The rim body includes an annular base wall and opposite annular side walls extending from the annular base wall. Each annular side wall includes a reinforcing segment connected to the annular base wall, and a tire coupling segment extending from the reinforcing segment. The tire coupling segments of the annular side walls cooperatively define a tire retaining space. Each reinforcing segment has an inner wall portion, an outer wall portion disposed at a radially outer side of the inner wall portion and cooperating with the inner wall portion to define an annular chamber, and at least one connecting wall portion disposed in the annular chamber, and cooperating with the inner and outer wall portions to form at least one H-shaped wall structure and to configure the annular chamber into at least two annular holes. | 10-28-2010 |
