FR2843580A1 - Multi-position regulating mechanism for handlebars of bicycles or motorcycles includes two half-bars articulatingly connected at one end and mounted on the fork by rotatable bridge assemblies - Google Patents

Abstract

The adjustable angle handlebars is formed from two half-bars (9,10) that are interconnected, at ends opposite to the handlebar grips, by an articulation arrangement (6). The half-bars are each mounted on a rotating bridge assembly (1-4), that is constituted by four parts in the form of a cylinder, and that via screws (11), couples the handlebars to the front fork of the cycle.

DESCRIPTION

  The present invention relates to a fixing device for

  handlebars for cycles and motorcycles.

  The adjustment of the handlebars is traditionally done by

  inclination in the original clamping bridges.

  The adjustment possibilities of a traditional handlebar are limited to the inclination by rotation on its axis without being able to modify the

  position of the ends which follow the angle of the hanger.

  The device according to the invention makes it possible to adjust the height, the

width and tilt of the handlebars.

  The principle of this set of revolving bridges and articulated handlebar makes it possible to obtain a position adapted to the morphology of each user. The advantage being to obtain for each angle adjustment a

  comfortable position of the ends for the handles.

  This assembly mounted on revolving bridges and assembled by a

  central spherical connection ensures the rigidity of the two demiguidons.

  The two half-handlebars are each mounted on a trigger guard, the ends of the half-handlebars opposite the handles being connected to each other by a joint. According to a characteristic of the invention, the revolving bridges each consist of four parts produced in the form of cylinders which secure the half-handlebars to the forks of cycles and motorcycles. Advantageously, the adjustments are obtained by rotation of the half-handlebars in the bridges themselves orientable by an amplitude of forty degrees (from - 20 degrees to + 20 degrees) relative to their axis of attachment. The accompanying drawings illustrate the invention: Figure 1 shows in section and seen from the front the device of the invention; Figure 2 shows a top view of the device in position; Figure 3 shows in section the exploded view of the device for rotating and fixing the assembly; -2 Figure 4A is a sectional view from above of the cylinder 1 of the invention; Figure 4B is a sectional view from above of cylinder 2 of the invention; Figure 4C is a sectional view from above of the cylinder 3 of the invention, and Figure 4D is a sectional view from above of the cylinder 4 of the invention.

  With reference to these drawings, the device comprises a system of 10 revolving bridges (see FIG. 3) which are fixed to the T of the forks.

  The central part 5 fits on each side in the cylinders 2 to prevent the rotation of the cylinders 2 on themselves and guarantees tightening

  of the assembly on the support of the fork T.

  The cylinders 2 fit into the locking rings 1. 15 The rotation cylinders 3 fit onto the cylinders 2.

  The positioning of the right 9 and left 10 half-handlebars is done between the cylinders 3 and 4. A marking on each half-handlebars serving

  Tilt marker allows you to place them in the same plane.

  The assembly is locked by four screws 11 between the 20 cylinders 1 and 4 passing through the cylinders 2 and 3.

  While the cylinders 2 are fixed on the fork T, the set of cylinders 1, 3 and 4 allow the angle of rotation to be adjusted

in the cylinder lights 2.

  The assembly thus composed is connected to the center by a system of 25 hingeable articulated ball joints after adjustment obtained.

  The tightening wheel 7 fits onto the sphere 6 which is screwed

in the right handlebar 10.

  The socket 8 is screwed into the left handlebar 9.

  The male sphere 6 enters the female sphere 8 which serves as a socket.

  The junction is ensured by the knob 7 which is screwed on

  the outside of the female sphere 8.

  We thus obtain a perfect symmetry between the two demiguidons 9 and 10.
