Embodiment Construction

[0059] figure 1 It is an assembly view showing an embodiment of the present invention, taking the bicycle frame 1 made of synthetic material as an example. The frame includes three hubs 2, 3, 4, which respectively include a seat connection 5, a sleeve for the pedal assembly 6, and a steering tube 7. The steering tube 7 is adapted to receive the upper end of the front fork 8 supporting the front wheel (not shown) of the bicycle.

[0060] The three axle hubs 2, 3, 4 are connected to each other by elongated tubular elements, that is, connected to each other by the upper tube or horizontal tube 9, the diagonal tube 10 and the seat tube 11, wherein the tube 9 connects the seat 5 is connected to the steering tube 7, the diagonal tube 10 connects the steering tube 7 to the pedal assembly sleeve 6, and the seat tube 11 connects the steering sleeve to the seat connection 5.

[0061] The frame at its rear includes two tubular elements forming bases 12, 13, which extend substantially horizon...

Abstract

The vehicle frame comprises: on back, two base parts (12, 13) almost-parallel extended backward to form a space for real wheel; two brackets (14, 15) inclined to extend toward and connect with one end of (12, 13) by sharp angle; and a couple of grooves between former parts and brackets for real wheel shaft, wherein every groove comprises a first / second notch (23) / (24) with a semi-spherical base arranged on a flat end on the base and the flat end of the bracket faced the (23) to align two semi-spherical bases.

Description

Technical field [0001] The present invention relates to a bicycle frame, in particular to the rear part of the bicycle frame, which includes two elements forming a bracket, these two elements are connected to two elements forming a base, these elements are designed to allow The rear wheel is fixed to the bicycle. Background technique [0002] In the existing metal frame, the element forming the bracket and the element forming the base are generally tubular, and the fixing tongues for the rear wheels are supported at their respective intersections. The fixing tongue is welded or fixed at the end of the element forming the base and includes a groove for the wheel axle. [0003] In the case of a frame made of synthetic material, the connecting device between the bracket and the end of the base is usually composed of two additional metal connecting parts. Each connecting member includes two arm portions, one of which is inserted into the rear end of one of the bases, and the other is...
