Abstract: A tire structure disposed at a rim is provided. The tire structure includes a tire body, a flexible sealing member and a nozzle. The tire body is ring-shaped and includes a groove and two beads. The flexible sealing member is connected to the tire body to form an inflating space with the groove, and the flexible sealing member includes a through hole. The nozzle is disposed at the flexible sealing member. The nozzle includes a base and a valve stem. The base includes a screw hole and is disposed at a far side of the flexible sealing member. The screw hole corresponds to the through hole. The valve stem includes a fastening end and an inflating channel. The fastening end is configured to insert into the screw hole, and the inflating channel is configured to allow the gas to pass therethrough.

Abstract: A tire assembling device includes a main body, a holding portion, an abutting surface, a guiding portion, a pressing portion and a protrusion. The main body has a top surface. The holding portion is connected to one side of the main body. The abutting surface connected to another side of the main body is for abutting against a rim surface of the rim. The guiding portion located between the abutting surface and the top surface is extended inclinedly corresponding to a radial direction of the rim. The pressing portion extended from the guiding portion toward a reference direction is protruded from the abutting surface and connected to the top surface. The protrusion protruded from the pressing portion forms a hook portion with an upper edge of the pressing portion and the abutting surface. The hook portion is for hooking a first edge of the rim.

Abstract: A bicycle saddle rail includes a first connecting structure, two arc rods and a second connecting structure. The first connecting structure includes a main body and two first connecting portions. Each of the arc rods has a first end and a second end, and each of the first ends of the two arc rods is integrally connected to one of the first connecting portions of the first connecting structure. The second connecting structure includes two second connecting portions, wherein each of the second connecting portions is integrally connected to one of the second ends of the two arc rods, respectively, and the second connecting structure is connected with the first connecting structure via the two arc rods, so that the first connecting structure, the two arc rods and the second connecting structure are connected to each other and formed the bicycle saddle rail with a closed structure.

Abstract: A distinguishing system for a saddle contacting mode includes a saddle and a deformable pressure sensing apparatus. The deformable pressure sensing apparatus is disposed on the saddle, wherein the deformable pressure sensing apparatus deforms in response to a sitting pressure, and a saddle type is determined in accordance with the deformation. The deformable pressure sensing apparatus can actually acquire the pelvis contact shape. The deformation is visible on the saddle after the sitting pressure is released, and the deformation can be compared with a comparison table to determine the suitable saddle type for the user instantly. Therefore, the distinguishing system could save the test time and reduce the production cost.
