DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following description and claims reference will be made to the non-limiting examples of a bicycle component such as a control assembly of bicycle handlebars, to be associated with a tubular element such as a handlebar tube, and a derailleur, to be associated with a tubular element such as a tube of the frame, in particular with the seat tube of the frame (i.e. that which supports the saddle tube of the bicycle at the top).

Advantageously, the aforementioned removable clamping device makes it possible to obtain quick mounting and dismounting of the bicycle component from the tubular element of the bicycle, through the clamping of the at least three clamping segments through the at least one removable fastener. In particular, the clamping is provided by the fastening of the at least one removable fastener between two clamping segments in succession. Such clamping has proven secure and reliable.

Preferably, the connection systems define hinging axes, parallel to one another along a direction according to which the tubular element is intended to be arranged when the bicycle component is fixed thereto, the hinging axes comprising a stable hinging axis for every hinge and a virtual hinging axis for every removable fastener. Under the expression virtual hinging it is meant that there is a hinging axis only when the fastening is closed, whereas the hinging axis disappears when the fastening is open, with its parts separated from one another.

In accordance with preferred features of the invention, the clamping device is capable of taking up at least three configurations:

- i) a clamped configuration, wherein:
  - the removable fastener is closed and the clamping segments are arranged in succession substantially defining a minimum closed line,
  - the hinging axes are all arranged close to such a minimum closed line, and
  - the clamping device is clamped when applied to the tubular element;
- ii) an open configuration, wherein:
  - the removable fastener is open and the clamping segments are arranged at least partially far from the minimum closed line,
  - at least one of the hinging axes is far from the minimum closed line, and
  - the clamping device can be positioned around the tubular element;
- iii) an intermediate configuration, wherein:
  - the removable fastener is closed and the clamping segments are arranged at least partially far from the minimum closed line,
  - at least one of the hinging axes is far from the minimum closed line, and
  - the clamping device is not clamped when applied to the tubular element.

Preferably, in a clamped configuration of the clamping device, when the bicycle component is fixed to the tubular element of the bicycle, there is surface abutment of the clamping device and of a rear surface of the main body at the tubular element.

Advantageously, the surface abutment at the tubular element increases the friction and stably locks the bicycle component on the tubular element.

Preferably, in a clamped configuration of the clamping device, one of the clamping segments is arranged at least partially juxtaposed over an adjacent clamping segment.

Advantageously, such a juxtaposed clamping segment has the effect of tightening the remaining clamping segments around the tubular element.

In an embodiment of the invention, the clamping segment arranged at least partially juxtaposed is rested on the adjacent clamping segment.

In another embodiment of the invention, the clamping segment arranged at least partially juxtaposed is at least partially recessed in a seat formed in the adjacent clamping segment.

Preferably, the component is a control assembly of bicycle handlebars or the component is a derailleur.

With reference to the figures, preferred embodiments of the invention are shown, some referring to a control assembly of handlebars or handlebar control assembly and others referring to a derailleur. In particular, reference numerals 10, 210 and 410 indicate three preferred embodiments of a control assembly of handlebars or handlebar control assembly in accordance with the present invention, whereas reference numerals 110, 310 and 510 indicate three preferred embodiments of a derailleur in accordance with the present invention.

The general term “bicycle component” includes the control assembly of handlebars 10, 210, 410 and the bicycle derailleur 110, 310, 510 in accordance with the present invention. Of course, the type of the specific bicycle component is not relevant for the purposes of the invention and therefore the features described hereinafter with specific reference to each of the aforementioned embodiments can be adopted for a control assembly of handlebars, for a derailleur, and for other component.

In any event, the bicycle component is intended to be fixed to a tubular element of the bicycle.

In the embodiments wherein the bicycle component is a control assembly of bicycle handlebars, the tubular element is a tube of the bicycle handlebars.

In the embodiments wherein the bicycle component is a bicycle derailleur, the tubular element is a seat tube of the frame (i.e. that which supports the saddle tube of the bicycle at the top).

With initial reference to the attached FIGS. 1-7, reference numeral 10 indicates a first preferred embodiment of a control assembly of bicycle handlebars in accordance with the present invention.

As illustrated in FIG. 1, the bicycle component 10 comprises a removable clamping device 20 for fixing to the tubular element (not illustrated) of the bicycle.

A main body 12 of the bicycle component 10 has a rear surface 14 configured to be associated with the tubular element and an opposite front surface 16.

The removable clamping device 20 comprises a plurality of clamping segments configured to be arranged around the entire circumference of the tubular element of the bicycle and to be removably clamped on it.

The clamping segments are connected together in succession in pairs by connection systems, wherein the connection systems comprise hinges and a removable fastener 40.

The connection systems define hinging axes, parallel to one another along a direction according to which the tubular element is intended to be arranged when the bicycle component 10 is fixed thereto; the hinging axes comprise a stable hinging axis for every hinge and a virtual hinging axis for the removable fastener 40.

In particular, in this embodiment of the invention, there are four clamping segments, indicated with 30, 32, 34 and 36, and there are three hinges, indicated with 31, 33 and 35.

The clamping segment 30 is fixed to the main body 12 of the bicycle component, through a pin 30a that is preferably externally threaded, or through a screw screwed into an axial cavity of such a pin, without external threading. As an alternative to the threaded connection just described, the clamping segment 30 can be fixed to the main body 12 through overmolding with the main body.

The clamping segment 30 is substantially V-shaped, with a first end portion, at which the hinge 31 is provided, and a second opposite end portion where a hook 40a is provided that forms part of the removable fastener 40.

The clamping segment 32 extends for an arc between a first end portion and a second end portion opposite the first, provided at the opposite end portions with the hinges 31 and 33, respectively.

The clamping segment 34 extends between a first end portion and a second end portion opposite the first, and is connected to the clamping segment 32 through the hinge 33, arranged at the second end portion of the clamping segment 32 and at the first end portion of the clamping segment 34.

The clamping segment 36 extends for an arc between a first end portion and a second end portion opposite the first, and is connected to the clamping segment 34 through the hinge 35, arranged at the second end portion of the clamping segment 34 and at an intermediate area of the clamping segment 36. The clamping segment 36 is provided at the second end portion with a counter-hook 40b, which forms part of the removable fastener 40.

The clamping device 20 is capable of taking up at least three configurations.

A first configuration is a clamped configuration (FIGS. 3, 5 and 7), wherein the removable fastener 40 is closed and the clamping segments 30, 32, 34 and 36 are arranged in succession substantially defining a minimum closed line (FIG. 7), the hinging axes are all arranged close to such a minimum closed line, and the clamping device 20 is clamped when applied to the tubular element;

A second configuration is an open configuration (FIGS. 2, 4 and 6), wherein the removable fastener 40 is open and the clamping segments 30, 32, 34 and 36 are arranged at least partially far from the minimum closed line, at least one of the hinging axes is far from the minimum closed line, and the clamping device 20 can be positioned around the tubular element;

A third configuration is an intermediate configuration (not illustrated in the figures but obvious from what has been described), wherein the removable fastener 40 is closed and the clamping segments 30, 32, 34 and 36 are arranged at least partially far from the minimum closed line, at least one of the hinging axes is far from the minimum closed line, and the clamping device 20 is not clamped when applied to the tubular element.

In the clamped configuration of the clamping device 20, when the bicycle component is fixed to the tubular element of the bicycle, there is surface abutment of the clamping device 20 and of the rear surface 14 of the main body 12 at the tubular element.

In the clamped configuration of the clamping device 20, the clamping segment 34 is arranged at least partially juxtaposed over the clamping segment 32.

The clamping segment 34 arranged at least partially juxtaposed is at least partially recessed in a seat 32a formed in the clamping segment 32.

The clamping segment 36 comprises an actuating end portion 36a.

The ways of using the clamping device 20 of the component 10 are clear from what has been described. In order to fix the component 10 to the tubular element of the bicycle, it is necessary to bring the clamping device 20 into its open configuration and arrange it around the tubular element so as to embrace it; at this point, the fastener 40 is closed (by fastening the hook 40a to the counter-hook 40b), reaching the intermediate configuration; finally, by acting on the end 36a of the clamping segment 36 in the direction to take the latter above and against the clamping segment 34 and this in turn above and against the clamping segment 32, the clamping condition is reached. At this point, the component 10 is locked on the tubular element of the bicycle in a secure and stable manner.

If it is wished to then dismount the component 10 from the tubular element of the bicycle, it is sufficient to carry out the previous operations in reverse.

As can be seen, both the mounting and the dismounting are simple and quick.

A first preferred embodiment of a bicycle derailleur 110 in accordance with the invention is illustrated in FIGS. 8-14, in which elements structurally or functionally equivalent to those already described with reference to the first embodiment of the control assembly of bicycle handlebars 10 of the invention are indicated with the same reference numeral.

In particular, in this embodiment of the invention, there are three clamping segments, indicated with 130, 132 and 134, and there are two hinges, indicated with 131 and 133.

The clamping segment 130 is fixed to the main body 12 of the bicycle component, at an appendage portion 130b thereof, equipped with a hole 130c. The hole 130c is passed through by a fixing screw to the main body 12.

The clamping segment 134 is provided at the second end portion with a counter-hook 40b, which forms part of the removable fastener 40.

The clamping device 120 is capable of taking up at least three configurations:

In the clamped configuration of the clamping device 120, the clamping segment 132 is arranged at least partially juxtaposed over the clamping segment 130.

The clamping segment 132 arranged at least partially juxtaposed is at least partially recessed in a seat 130a formed in the clamping segment 130.

The clamping segment 134 comprises an actuating end portion 134a.

The ways of using the clamping device 120 of the component 110 are clear from what has been described. In order to fix the component 110 to the tubular element of the bicycle, it is necessary to bring the clamping device 120 into its open configuration and to arrange it around the tubular element so as to embrace it; at this point, the fastener 40 is closed (by fastening the hook 40a to the counter-hook 40b), reaching the intermediate configuration; finally, by acting on the clamping segment 134 in the direction to take it above and against the clamping segment 132 and this above and against the clamping segment 130, the clamping condition is reached. At this point, the component 110 is locked on the tubular element of the bicycle in a secure and stable manner.

If it is then wished to dismount the component 110 from the tubular element of the bicycle, it is sufficient to carry out the previous operations in reverse.

As can be seen, both the mounting and the dismounting are simple and quick.

A second preferred embodiment of the control assembly of bicycle handlebars 210 in accordance with the invention is illustrated in FIGS. 15-22, in which elements structurally or functionally equivalent to those already described with reference to the prima embodiment of the control assembly of bicycle handlebars 10 of the invention of FIGS. 1-7 are indicated with the same reference numeral.

The ways of using the clamping device 220 of the component 210 are clear from what has been described. In order to fix the component 210 to the tubular element of the bicycle, it is necessary to take the clamping device 220 into its open configuration and to arrange it around the tubular element so as to embrace it; at this point, it is possible to adjust the width of the clamping device 220, unscrewing or screwing in the threaded head of the clamping segment 236 in the bush 260; thereafter, the fastener 40 is closed (by fastening the hook 40a to the counter-hook 40b), reaching the intermediate configuration; finally, by acting on the end 234a of the clamping segment 234 in the direction to take the latter above and against the clamping segment 232, carrying the clamping segment 236 above it, the clamping condition is reached. At this point, the component 210 is locked on the tubular element of the bicycle in a secure and stable manner.

If it is then wished to dismount the component 210 from the tubular element of the bicycle, it is sufficient to carry out the previous operations in reverse.

As can be seen, both the mounting and the dismounting are simple and quick.
