Description

DRIVING SYSTEM AND EQUIPPED CONTROL DEVICE

WITH A SYSTEM OF THIS TYPE, FOR A MANAGEMENT BODY OF

A BICYCLE

5
The object of the invention is a drive system and a

control device equipped with such a system, for an organ of

maneuver of a vehicle, for example a brake or shift mechanism

of gears.

The invention finds, for example, an application for control and

the
actuation of a braking mechanism of a bicycle or a scooter.

In general, to control a maneuvering organ of a

bicycle, for example a braking or gearshift mechanism, is

use an eccentric control device attached to the organ that must be

control via a correctly installed drive cable.

fifteen
When exerting traction, for example by means of a brake lever,

on the cable, the braking mechanism is activated, for example, a stirrup that

It has a pair of brake shoes that will rub on the wheel. When you release the

brake lever, the cable returns to its normal position and the shoes move away

of the wheel.

twenty
Similarly, when exerting traction, for example by means of a

operating lever or by any other equivalent element, it

drives the gearshift mechanism that makes the chain of the

bicycle deviates so that it changes plate or pinion.

For such a control device, and its system of

25
drive, work efficiently it is necessary that the voltage of the

resting cable, that is, in the non-actuating position of the

maneuver, is properly adjusted, so that traction on the

cable implies the effective operation of this maneuvering organ.

This voltage can be adjusted over time. In addition, in the case in

30
Particular of the braking mechanism with brake shoes mounted on

a stirrup, these shoes wear progressively over time.

It is therefore necessary to be able to easily modify the regulation

of this tension to adjust it correctly.

On the other hand, some users may prefer one more type of adjustment

35
that other. For example, a user may want "dry" braking from the

z

start of the drive path of the drive system. On the contrary, another user may want progressive "soft" braking along the drive path of the drive system. In both cases, the adjustment of the cable tension is not the same.

It is therefore also necessary here to be able to easily modify the regulation of this voltage to adjust it correctly according to the desire

of the user. Drive systems in which the cable tension can be regulated by means of a nut / locknut type system are common.

In these drive systems, the cable, usually covered, is connected to the maneuvering organ by one of its ends, and is provided at its opposite end with a threaded stop of the cover which is

screw at the same time inside the body of the control device for example

a brake lever and inside an adjustment wheel or a nut

which leans against the body.

By unscrewing the stop of the lever body cover, the cable is stretched and corrected in this way, for example, the wear of the brake shoes

On the contrary, by screwing the cover stop on the lever body, the cable is tensioned, which allows the adjustment to be modified, for example

after replacing the used shoes with new shoes.

One of the problems posed by this type of drive system is that the adjustment can be difficult for users to understand and difficult to implement. In fact, in order to be able to screw or unscrew the cover stop, first of all the nut or the adjusting wheel must be slightly unscrewed. Then once the stop

screwed or unscrewed conveniently, the nut must be tightened again against the lever body.

Another problem with this type of device is that, when

make an adjustment to compensate for the wear of the brake shoes, the stop

of the cover protrudes enough from the body and the nut screwed to the body reveals a part of the threading of the cover stop.

The invention is therefore intended to solve the problems that have been exposed, among other problems.

The invention thus relates, according to a first aspect, to a drive system of a maneuvering organ of a vehicle for example a bicycle, the maneuvering organ being, for example, a braking or changing mechanism of gears, suitable for being controlled by a control device, for example a brake or gearshift lever, comprising a body having a receiving portion.

The drive system comprises a drive cable mounted within a cover, the first end of which is intended to slide into the receiving portion and to be fixed to the control device, and the opposite end of which is intended to be fixed on the control element.

maneuver. The system also includes adjustment means intended for

regulate the tension of the cable between the operating device and the device

I send. These adjustment means comprise a threaded stop suitable for serving

as a stop at the end of the cable cover during operation of the

drive system The adjustment means also comprise a wheel suitable for mounting cooperating around the receiving portion, and the stopper is

screwed into the adjustment wheel and is suitable for sliding into the receiving portion, in such a way as to allow adjustment of the tension of the

cable by wheel rotation. In this way, it is enough to turn the wheel, which has the effect

Screw or unscrew the wheel stop, which causes the stop to move along the axis of the cable, to adjust the tension of this cable. In addition, once mounted on the control device, for example

a brake lever, whatever the setting, you don't see any unsightly

threaded since the threading of the stop is inside the adjustment wheel. Likewise, the adjusting wheel may have a grip surface greater than the nut / locknut system of the prior art, thereby

that the adjustment needs less precision and less force.

In a first embodiment, the adjustment wheel has a first end intended to rest on an outer flange of the receiving portion, and has an inner flange intended to rest on the end of the receiving portion.

In this variant, the stop may be provided with a flange suitable for

rest on the flange of the adjustment wheel. Preferably, the adjustment wheel has a second end

opposite the first end provided with a passage hole for the cable. In a second variant, possibly in combination with the previous one, the wheel has a cylindrical or frustoconical outer shape. In a third variant, possibly in combination with one or more of the above, the outer wall of the adjustment wheel is provided with

less a flat part that facilitates the grip of the wheel by the user.

The invention also relates, according to a second aspect, to a control device, for example a lever or a brake or gearshift lever, of a vehicle, for example a bicycle, for the control of an organ of maneuver of this vehicle, for example a mechanism of

braking or gearshift. The device comprises a drive system like the one

He has presented previously.

In a variant, the device comprises a body that receives, by means of a reception portion at the first end of the cable mounted slider in this reception portion, the adjustment wheel being mounted

cooperating around the receiving portion, and the screwed screw stop

inside the wheel being slidably mounted inside the receiving portion.

Preferably, the outer wall of the adjustment wheel at the height of its

The first end is prolonged without interruption by the outer wall of the receiving portion of the body.

The invention also relates, according to a third aspect, to a vehicle, for example a bicycle, comprising at least one maneuvering organ, for example a braking or gearshift mechanism, this maneuvering organ being controlled by a control device like the one presented previously.

Other features and advantages of the invention will be shown with greater

clarity and completely with the reading of the description given to

continuation of the preferred embodiments, which are given by way of non-exclusive examples and in reference to the following accompanying drawings:

-
Figure 1: schematically represents an example of a control device with the drive system according to the invention, seen in partial section;

-
figure 2: schematically represents the device of figure 1

as a whole, with an extension of the drive system adjustment wheel.

Typically, the control device comprises a body 1 and a lever 7, integral with the body 1 and intended to start the drive system.

The drive system comprises a cable 2 protected by a cover 10, whose first end 2a protrudes out of the cover 10 and is

connected directly or indirectly to the lever 7, such that a user

it can exert traction on the cable 2 when acting on the lever 7.

At the end of the cable 2 opposite the first end 2a, no

shown in figure 1, the cable 2 is fixed to the braking mechanism, of

such that the traction on the cable 2 activates the braking mechanism.

This first end 2a of the cable 2 is introduced by sliding into a receiving portion 1 a of the body 1.

On the other hand, the drive system comprises means of

adjustment 3, 8 intended to allow adjustment of the tension of the cable 2.

These adjustment means comprise a wheel 3 that cooperates in one 3a

from its ends 3a, 3b with and around the end of the receiving portion 1 to opposite the end of the portion integral with the body 1. The end 3a of the adjusting wheel 3 rests on a flange

exterior 4 of the reception portion 1a.

This end 3a of the adjusting wheel 3 is provided, on the one hand, with

an edge of the annular end that rests on the end of the portion of

reception 1a and, on the other hand, of an inner flange 5, slightly behind the axis with respect to the edge of the annular end.

At its end 3b opposite end 3a, the adjustment wheel 3 is

provided with a hole for the passage of the cable 2.

6 7

The adjustment means 3, 8 of the tension of the cable 2 comprise,

another part, a threaded stop of the cover 8, slidably mounted inside the

Reception portion 1a and mounted screwed inside the wheel 3.

This stop 8 is suitable to serve as a stop at the end of the cover

The stop 8 comprises a flange 9, at its opposite end to the end of

Introduction by screwing into the adjusting wheel 3, which can be

rest on the inner flange 5 of the wheel 3 presented in paragraphs

above, so that the stop 8 cannot be screwed inside the

wheel 3 beyond the support of the flange 9 of the stop 8 over the flange 5 of the

fifteen
wheel 3.

Thus, by turning the adjustment wheel 3, in one direction or the other,

around the receiving portion 1 a, the stop 8 is screwed or unscrewed

inside the wheel 3 sliding at the same time inside the portion

of reception 1a, which has the effect of modifying the adjustment of the

2 o
cable tension 2.

Figure 2 shows more generally the example of a device for

command with its drive system described above in

reference to figure 1, presented this time without cutting.

As depicted in both Figure 1 and Figure 2, in

3 o
outside of the adjusting wheel 3 from its end 3b, to facilitate the grip of

the wheel 3 by the user.

The outer shape of the adjusting wheel 3 is tapered, slightly

narrower at its end 3b than at its end 3a. It could also be

cylindrical or even otherwise.

However, it is preferred that this form allows both cooperation with the end of the receiving portion 1a of the body and allows

that the outer walls of the wheel 3 are extending without

interruptions to the exterior walls of this reception portion 1a.

5 The set of the previous description is given as an example and, therefore

therefore, it does not limit the invention.

In particular, the main application relates to the control and operation of a maneuvering organ, for example a braking mechanism or a gearshift mechanism, for a bicycle.

10 But the invention extends to the actuation and control of any operating device that uses a cable to connect the eccentric control and the operating element, and to exert an action on the operating element from the control device and its system drive.

Similarly, the invention extends to the drive and control 15 of a maneuvering body not only of a bicycle but of any other

vehicle, for example a scooter.
