Embodiment Construction

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

[0060] The three hubs 2, 3, 4 are interconnected by elongated tubular elements, that is to say by an upper or horizontal tube 9, a diagonal tube 10 and a saddle tube 11, wherein the tube 9 connects the saddle 5 is connected with the steering tube 7, and the diagonal tube 10 is connected with the steering tube 7 and the pedal assembly bushing 6, and the seat tube 11 is connected with the steering bushing and the seat connection 5.

[0061] The frame comprises, at its rear, two tubular elements forming a base 12, 13 extending rearwards substantially horizontally so as t...

Abstract

A vehicle frame comprising at the rear two bases (12, 13) extending rearwardly substantially parallel to define between them a space; and two brackets (14, 15) extending obliquely towards a respective end of said base (12, 13) and connected thereto at an acute angle by means of connecting means, between said two brackets The intersection of (14, 15) and said two bases (12, 13) is substantially provided with a pair of grooves for the axles of the rear wheels. Each groove in the pair of grooves includes: a first notch (23) with a semicircular bottom disposed at one flat end of the base; and a second notch (24) with a semicircular bottom ), which is provided at one flat end of the bracket, and is arranged to face the first notch (23), so that the two semicircular bottoms will be aligned with each other.

Description

technical field [0001] The present invention relates to a bicycle frame, in particular to the rear part of a bicycle frame, comprising two elements forming a bracket connected to two elements forming a base, the elements being designed to allow the The rear wheel is fixed to the bicycle. Background technique [0002] In known metal vehicle frames, the element forming the bracket and the element forming the base are substantially tubular and support, at their respective crossings, fastening tongues for the rear wheel. This fastening tongue is welded or fastened at the end of the element forming the base and comprises a groove for the wheel axle. [0003] In the case of frames made of composite material, the connecting means between the bracket and the end of the base usually consist of two additional metal connecting parts. Each connection part comprises two arms, one of which is inserted into the rear end of one of the bases and the other is inserted into the end of the co...
