Background of the invention

The present invention relates to a fender for mounting on a bicycle. In particular, it finds application for bicycle equipment and cycling, in order to allow the user and the frame of the bicycle to be protected against the elements projected by the wheels of the bicycle, in particular when the bicycle is used on muddy ground or in the rain.

Various types of mudguards are known which can be mounted permanently on the bicycle they equip. Also known are mudguards configured to be removably mounted on a bicycle.

Such an example of mudguard is in particular disclosed by the document EP 2,060,479 which describes a mudguard intended to be mounted on a bicycle comprising a frame, the mudguard comprising a piece of protection against projections and a piece fixing device, mounted on the protective part, having an oblong slot to allow the fixation of the fender, by a system of screws and nuts arranged through the oblong slot, on the frame of the bicycle.

The problem with this type of fender is that it can be mounted on a limited number of different bicycles, the dimensions of the oblong slot does not allow it to be adapted to multiple bicycle frames forms and to different dimensions. In addition, the attachment of the fastener requires the use of a suitable tool, which complicates the assembly of the fender. Finally, the fastener being arranged in a single direction relative to the protective part, its inclination can not be changed, such inclination being particularly useful for adapting the mudguard to different types of bicycles. Object and summary of the invention

The present invention aims to provide a mudguard that can be easily and securely mounted on bicycles of different sizes and shapes, without requiring the use of tools.

This object is achieved by the fact that the invention relates to a fender comprising at least a first mounting means comprising:

- a base attached to the protection piece; and

a fixing head mounted on the base in an articulated manner and comprising a detachable fixing means for fixing the fixing head to the frame of the bicycle.

Thus, this device makes it easy and secure to mount a fender on a bicycle.

In addition, the possibility for the fixing head to be articulated relative to the base allows the fender to be adapted to different shapes and sizes of bicycle frames, as well as to different shapes and sizes of wheels. bicycles whose projections the mudguard is configured to protect.

The presence of the detachable fastening means removably mount the mudguard on the frame of the bicycle.

The invention is described below in a series of alternative embodiments, which may be considered alone or in combination with one or more of the previous ones.

Advantageously, the fixing head is pivotally mounted relative to the base.

By this arrangement, the angular position of the detachable fastening means of the fixing head can be modified, to be adapted to different configurations of bicycle frames. Advantageously, the axis about which the fixing head is pivotally mounted relative to the base is substantially parallel to the axis of rotation of the wheel on which is mounted the mudguard.

Preferably, the pivot axis of the fixing head is substantially horizontal, when the bicycle is arranged to be set in motion.

Advantageously, the base comprises a first and a second lateral portion extending transversely relative to the protective part, the fixing head being pivotally mounted relative to the lateral portions.

Advantageously, the first and second lateral portions extend substantially perpendicularly with respect to the protective part, towards the outside of the protective part.

Preferably, the first and second lateral portions extend substantially parallel to each other.

By outside of the protective piece is meant the region opposite to that in which the wheel against the projections of which the protective part of the fender is configured to protect.

In other words, the interior of the mudguard designates the region delimited by the protective part, in which is located the wheel of the bicycle on which the mudguard is mounted, and from which elements can be projected, in particular during the rotation of the wheel.

Advantageously, the base comprises a first and a second pin projecting respectively from the first and second lateral portions.

Advantageously, the first and second pins are directed toward each other and define the axis about which the fixing head can be pivoted relative to the base. Preferably, the axis defined by the first and second pins is transverse, preferably perpendicular to the plane defined respectively by the first and second lateral portions.

By this arrangement, it is understood that the fixing head, and therefore the detachable fastening means, can be inclined relative to the protective part of the fender, so as to allow the mounting of the mudguard on different configurations and bicycle dimensions and to adapt the position of the detachable fastening means to different geometries of the frame of the bicycle.

Advantageously, the fixing head can be moved relative to the base in a direction transverse to the protective part, so as to adjust the distance between the fixing head and the protective part.

It is also understood that by this arrangement, the distance between the protective part of the fender of the wheel of the bicycle can be adjusted. In other words, the height of the attachment head relative to the mudguard protection part according to the present invention can be adjusted.

Advantageously, the fixing head comprises a first and a second lateral edge, disposed on either side of the detachable fastening means.

Preferably, the first and second side edges are substantially parallel to each other.

Advantageously, the fixing head comprises at least a first and a second orifices respectively formed in the first and second lateral edges, and dimensioned so as to respectively receive the first and second pins.

Advantageously, the fixing head has a first and a second series of orifices respectively formed in the first and second lateral edges. This feature makes it possible to have different positions of adjustment of the distance between the frame of the bicycle and the protection part of the fender, at the first mounting means, so as to allow the user to use the guard -bugs on different shapes and sizes of bicycle frames.

Preferably, according to a first embodiment, the first and second pins have, considered in a plane substantially parallel to that defined respectively by the first and second lateral portions, a substantially circular section, the constrictions being respectively formed between two first and two second consecutive orifices.

It is therefore understood that the displacement of the fastening head relative to the base in a direction transverse to the fastening piece may be allowed by a force displacement of the first and second pins from one orifice to another, l Strangulation being formed, for example and without limitation, in a slightly elastic plastic material, so as to allow a temporary spacing of the constriction during the passage of the first and second pins.

Advantageously, according to a second embodiment, the pins have first and second sides, one of the sides having a length, considered in the plane defined respectively by the first and second lateral portions, lower than the other side, constrictions being respectively formed between two first and two second consecutive orifices.

It is therefore understood that by pivoting the articulated head relative to the base, the pins can be engaged in the constriction formed between two consecutive orifices respectively formed in the first and second lateral edges.

Advantageously, the detachable fastening means of the fixing head comprises a housing delimited between a first and a second wing configured to move elastically apart from one another, a part of the frame of the bicycle can be engaged in the housing to attach the attachment head to the frame of the bicycle.

By this arrangement, it is understood that the first mounting means can be mounted easily on the frame of the bicycle, without requiring the use of tools, the first and second wings being configured to enclose a part of the frame of the bicycle.

Preferably, the protection member has an end and the fender further comprises a telescopic mounting means slidably mounted relative to the end of the protective part, the telescopic mounting means having a mounting portion configured to be engaged around a part of the bicycle frame.

By this arrangement, the mudguard has a second mounting device on the frame of the bicycle, in addition to that constituted by the detachable fastening means of the fixing head of the first mounting means, thereby further increasing the stability of mounting the fender on the frame of the bicycle.

It is understood that the first and second mounting devices operate completely independently of one another; it would thus be possible to design a fender comprising only one or the other of the first and second mounting devices, without departing from the scope of the present invention.

Furthermore, the possibility for the telescopic mounting means to slide relative to the end of the protective part allows it to adapt to different configurations and dimensions of bicycle frame.

Advantageously, the mounting portion has first and second resilient legs configured to be disposed around said portion of the frame of the bicycle.

By this arrangement, the mounting portion can easily be mounted on the frame of the bicycle, by removing the first and second elastic limbs one of the other. The use of an elastic material, of the plastic type, allows the elastic branches to grip the part of the frame of the bicycle, to allow its solid attachment. In addition, the presence of the first and second elastic branches allows the mudguard to be mounted on the frame of the bicycle, by the telescopic mounting means, without requiring tools.

In other words, the part of the frame of the bicycle enclosed by the mounting portion is held between the two elastic branches of the mounting portion.

Advantageously, the mudguard according to the present invention further comprises at least one telescopic rod having a longitudinal direction, the telescopic rod comprising:

an arm configured to be fixed to the protection piece;

- A fastener which cooperates with the arm and which comprises a detachable assembly means for fastening the fastener detachably to the frame of the bicycle; and

a locking member slidably mounted on the arm between an unlocked position, in which the position of the fastener relative to the arm can be modified to adjust the length of the telescopic rod, and a locked position, in which locking member locks the position of the fastener relative to the arm.

By this arrangement, the mudguard has a third mounting device, further increasing the stability and strength of mounting the fender on the frame of the bicycle.

It is also understood that the first, second and third mounting devices can operate completely independently of each other; it is thus possible to design a fender with only one mounting device, or any combination two mounting devices, without departing from the scope of the present invention.

In a manner similar to the previous mounting devices described, the detachable assembly means of the telescopic rod makes it possible to easily and securely mount a fender on a bicycle, the presence of the fixing piece and the sliding mounted locking member. to adapt the dimensions of the telescopic rod to those of the bicycle on which the mudguard is intended to be mounted.

Furthermore, the presence of detachable assembly means removably mount the mudguard on the frame of the bicycle.

The fact that, when the locking member is in the unlocked position, the position of the fastener relative to the arm can be modified, makes it possible to adjust the length of the telescopic rod, and, consequently, to adapt the dimensions of the mudguard to those of the wheel whose mudguard protects from projections and those of the frame of the bicycle.

Moreover, the locking of the fastener relative to the arm ensures the strength and stability of mounting the fender on the frame of the bicycle, and thus to avoid accidental changes in the length of the rod telescopic, even any accidental disassembly of the mudguard.

The possibility for the locking member to move from one to the other of the unlocked and locked positions by the sliding of the locking member along the arm allows the fender to be mounted easily and quickly on the frame of the bicycle, without requiring the use of tools. In addition, the fact that the locking member is mounted on the arm allows it to be held on the fender and not be separated, thereby avoiding any risk of loss of the locking member.

Preferably, the detachable mounting means is rotatably mounted relative to the arm. Advantageously, the axis of rotation of the detachable mounting means is transverse, preferably perpendicular, with respect to the longitudinal direction of the telescopic rod.

Advantageously, the axis of rotation of the detachable mounting means is substantially parallel to the axis of rotation of the wheel on which the mudguard is mounted.

The possibility for the detachable mounting means to be pivoted relative to the arm allows it to be adapted to the different possible configurations of the frame of the bicycle, so, in particular, to facilitate actuation.

Preferably, the telescopic rod further comprises a locking device for locking the sliding of the locking member relative to the arm.

Advantageously, the locking device is also configured to lock the sliding of the locking member relative to the fastener.

The locking device makes it possible to block the locking member in one or the other of the locked and unlocked positions. Thus, the mudguard does not risk, in particular, to be accidentally removed from the frame of the bicycle, or the length of its telescopic rod is not likely to be accidentally modified, for example when using the bicycle .

Preferably, the locking device comprises a groove formed on the locking member and a projection formed on the fastener, the projection being configured to be engaged in the groove when the locking member is in the locked position, so as to to clip the locking member on the fastener.

By this arrangement, locking the sliding of the locking member relative to the arm can be achieved easily by simply blocking the locking member and the fastener. Preferably, the locking member comprises a sleeve disposed around a portion of the arm and the fastener, the sleeve of the locking member being configured to slide relative to the arm and the fastener, more particularly for sliding around at least a portion of the arm and the fastener.

Advantageously, the fastener and the arm respectively comprise first and second rack portions configured to ensure the cooperation of the fastener with the arm.

Preferably, the arm has a first end, configured to be attached to the shield, and a second end, opposite the first end, the fastener cooperating with the second end of the arm.

Advantageously, the arm is pivotally mounted relative to the protective part, so as to move the telescopic rod relative to the frame of the bicycle, such a mobility allowing, inter alia, to facilitate the mounting of the detachable assembly means on the frame of the bicycle.

It is therefore understood that the length of the telescopic rod can be defined as being the distance separating the first end of the arm by detachable assembly means of the fastener.

Advantageously, the mudguard comprises first and second telescopic rods respectively having first and second longitudinal directions.

Preferably, the two telescopic rods are connected to one another by a connecting piece fixed to the protection piece.

Advantageously, the first and second telescopic rods are fitted into the connecting piece. Advantageously, the first and second longitudinal directions are substantially parallel to each other, particularly when the mudguard is mounted on the frame of the bicycle.

By this arrangement, the bicycle, and more particularly one of its wheels, is arranged between the first and second arms, so that the mudguard is held stably, when mounted on the frame of the bicycle. .

It is therefore understandable that the presence of the first and second telescopic rods avoids any risk that the mudguard will tilt on one side or the other of the frame of the bicycle, during the use of the bicycle.

Preferably, the invention also relates to a bicycle comprising a frame and at least one fender according to the present invention.

Advantageously, the bicycle further comprises a wheel and a hub around which said wheel is rotatably mounted, the detachable assembly means of the telescopic rod being configured to fix the fastener to the frame of the bicycle, close to the hub. .

By this arrangement, the telescopic rod is disposed facing one of the faces of the wheel.

In the embodiment in which the fender has a first and a second telescopic rods, the wheel is held between the two telescopic rods, so that the mudguard can not tilt towards one or the other. sides of the bicycle, such a change compromising the safety of the user of the bicycle, or even people moving nearby.

Detailed description of the invention

Figure 1 shows schematically a bicycle 100 having, in the traditional way, a frame 102, a front wheel 104 and a rear wheel 106; the frame 102 comprises a saddle 108, a handlebar 110, a front hub 112 and a rear hub 114 respectively defining a first and a second axis, parallel to each other, the front wheels 104 and rear 106 being configured to be rotated respectively about the axes defined by the front hubs 112 and rear 114. The frame 102 further comprises a pedal 116 having a plate, a portion of which is not shown for the sake of clarity, the pedal 106 being configured to rotate the rear wheel 106 about the axis defined by the rear hub 114 , a seat tube 125 disposed between the saddle 108 and the pedal 116, a fork 118 linking the front hub 112 to the handlebar 110, and stays 120 linking the rear hub 114 to the seat tube 125.

In addition, the front wheel 104 comprises a tire 122 and a front fender 200; the rear wheel 106 has a rear tire 124 and a rear fender 400.

Figures 2, 3 and 4 show in detail the front mudguard 200.

The front mudguard 200 comprises a protective member 202, a first mounting means 204, configured to attach the mudguard 200 to the frame 102 of the bicycle 100, and more particularly to the fork 118; in addition, the front fender 200 comprises a first 206 and a second 206 'telescopic rods configured to attach the protective part 202 of the front fender 200 on the frame 102 of the bicycle 100, and more particularly near or on the front hub 112.

Furthermore, the front fender 200 has a connecting piece 207, disposed on the protective member 202, and configured to bind the first 206 and second 206 'telescopic rods to each other.

For example and without limitation, the first 206 and second 206 'telescopic rods and the connecting piece 207 constitute a single element.

Naturally, it will be possible to conceive, without departing from the scope of the present invention, an alternative embodiment in which the first 206 and second 206 'telescopic rods are both fitted into housings formed in the connecting piece 207, in order to allow the removable mounting of the telescopic rods 206, 206 'on the protective part 202 of the mudguard 200.

The connecting piece 207 has an inner portion 209, disposed against or near the face of the protective member 202 facing the wheel, so as to strengthen the connection of the first 206 and second 206 'telescopic rods.

As shown in particular in FIGS. 2 and 3, the protection piece 202 has a first end 208 and a second end 210, opposite the first end 208.

For example and without limitation, the protective piece 202 has a curved shape, the protective part 202 being configured so that at least a portion of the tire 122 of the front wheel 104 is disposed in, or at least near, the interior volume of the convexity of the protective piece 202; in other words, the protection piece 202 is configured to cover a portion of the tire 122, or even to cover a portion of the lateral flanks of the tire 122.

The protection piece 202 has an inner face 212, configured to be directed towards the wheel 104, and more particularly towards the tire 122, and an outer face 214, opposite to the inner face 212. The protection piece 202 also has a first 216 and second 216 'side edges, which extend substantially parallel to each other; it is therefore understood that the lateral edges 216, 216 'are arranged so as to cover part of the flanks of the wheel 104.

In addition, the protection part 202 comprises a first 218 and a second 220 visors, respectively mounted on the first 208 and second 210 ends, and also configured to oppose the projection of elements by the front wheel 104 when it is rotated. For example and without limitation, the first 218 and second 220 visors may be fitted into the body of the protective part 202, and more particularly in a longitudinal cavity formed in the protective part 202. In other words, the first and second 218, 220 visors are configured to be nested at the ends 208, 210 of the protection piece 202.

The first 206 and second 206 'telescopic rods of the front fender 200 respectively extend from the first 216 and second 216' side edges of the protective member 202, to the wheel 104; in other words, the telescopic rods 206, 206 'are configured to be disposed on each side of the wheel 104, the wheel 104 defining, for example and without limitation, a plane of symmetry disposed between the first and second 206, 206 'telescopic rods.

The first telescopic rod 206 has a longitudinal direction I and comprises an arm 222 having a first longitudinal 224 and a second longitudinal 226 opposed to one another, the first longitudinal end 224 being fixed to the first lateral edge 216 of the piece 202. In addition, the first telescopic rod 206 has a fastener 228 mounted, when the front mudguard 200 is mounted on the frame of the bicycle 100, on the second longitudinal end 226 of the arm 222.

In the remainder of the description, the longitudinal direction of the arm 222 will be assimilated to the longitudinal direction I of the first telescopic rod 206.

As shown in Figure 3, which shows a partially exploded view of the front fender 200, as well as in Figure 4, which shows a sectional view of the second longitudinal end 226 of the arm 222 on which is mounted the piece fixing 228, the fastener 228 has an adjustment portion 230 and detachable assembly means 232.

The adjustment portion 230 comprises a first 233 and a second 233 'lateral portions, disposed on either side of the second longitudinal end 226 of the arm 222 when the fastener 228 is mounted on the telescopic rod 206; in addition, the adjustment portion 230 has a median portion 234 disposed between the first and second lateral portions 233, 233 ', the middle portion 234 being disposed facing the portion of the arm 222 with which the fastener 228 is configured to cooperate; the middle portion 234 has an inner face 236 disposed opposite the arm 222 when the fastener 228 is mounted on the telescopic rod 206 and an outer face 238, opposite the inner face 236; it is therefore understood that the adjustment portion 230 has a U-shaped profile, the lateral portions 233, 233 'and the middle portion 234 constituting respectively the branches and the bottom of the U, the adjustment portion 230 being sized to receive a portion arm 222, and more particularly its second longitudinal end 226.

The fastener 228 further has a first rack portion 240, with a first set of teeth 242, 242 ', the first rack portion 240 being formed transversely, preferably perpendicularly, to the inner face 236 of the middle portion 234. .

The arm 222 comprises, for its part, an inner face 244 disposed opposite the front wheel 104 when the front fender 200 is mounted on the frame 102 of the bicycle 100, and an outer face 246, opposite to the face internal 244; a second rack portion 248 is formed on the inner face 244 of the arm 222, at least on the inner face 244 of its second longitudinal end 226, the second rack portion 248 having a second set of teeth 250, 250 'formed transversely, preferably perpendicularly, to the inner face 244.

The first 240 and second 248 rack portions are dimensioned to cooperate with each other, i.e. the distance between two consecutive teeth of the first set of teeth 242, 242 'is equal, even slightly greater than the width of the teeth of the second series of teeth 250, 250 ', and, symmetrically, the distance separating two consecutive teeth of the second series of teeth 250, 250' is equal to or slightly greater than the width of the teeth of the first series of teeth 242, 242 '.

As will be detailed in the following description, the first 240 and second 248 rack portions are configured to allow, by their coupling, the longitudinal locking of the fastener 228 relative to the arm 222.

In addition, the adjustment portion 230 is dimensioned so as to cover at least a portion of the arm 222, and more particularly a portion of its inner face 244, the inner face 236 of the middle portion 234 being disposed facing the inner face. 244 of the arm 222, the lateral portions 233, 233 'being arranged along the longitudinal edges of the arm 222.

The position of the fastener 228 can thus be adjusted along the arm 222; more particularly, by cooperation of the first and second 240, 248 rack portions, the position of the adjustment portion 230 of the fastener 228 can be adjusted relative to the second longitudinal end 226 of the arm 222.

The detachable assembly means 232 of the fixing piece 228 comprises a fixing arm 252 which extends from one end 231 of the adjustment portion 230, and an assembly member 254 pivotally mounted relative to the attachment arm 252. . The connecting element 254 includes, for example and without limitation, a fin 256 and an actuating means 258, the fin and the actuating means defining a cavity 260 of shape, for example and in a non-limiting manner. limiting, substantially frustoconical.

It is understood that the pivoting of the connecting element 254 with respect to the fixing arm 252 makes it possible to arrange the connecting element 254 in such a manner as to make it easier for the user to access the actuating means 258. , and also makes it possible to adapt the arrangement of the connecting element 254 to the presence of elements on the frame 102, in particular near the front hub 112.

As shown in particular in Figure 1, the detachable assembly means 232 of the fastener 228 is configured to cooperate with a mounting pad (not shown), formed or fixed on the frame 102 of the bicycle 100, and disposed more particularly close to, or on, the front hub 112.

It is also understood that by actuating the actuating means 258, the dimensions of the cavity 260 are increased, so as to be able to withdraw the stud from the cavity 260, to allow the dismounting of the front fender 200 of the frame 102 of the bicycle 100.

Thus, by arranging the attachment piece 228 on the arm 222, and more particularly near its second longitudinal end 226, the position of the detachable assembly means 232 can be adjusted so as to adapt the position of the assembly means detachable 232 on the telescopic rod 206 to that of the mounting pad, and, consequently, so as to adapt to the dimensions of the bicycle 100.

In other words, the displacement of the fastener 228 with respect to the arm 222 makes it possible to adjust the length of the telescopic rod 206. By length of the telescopic rod 206, the distance, considered in the longitudinal direction I, is understood separating the first end 224 of the arm 222, by which the arm 222 is attached to the protective part 202, on the one hand, the detachable assembly means 232, on the other hand.

As shown in the various figures, the fixing piece 228 can take different positions on the arm 222, these different positions being permitted by the different positions that can take the first 240 and second 228 rack portions with respect to the 'other.

In each of the different positions that the attachment piece 228 can take on the arm 222, the second longitudinal end 226 of the arm 222 is disposed between the detachable assembly means 232 and the first longitudinal end 224 of the arm 222. It could also be conceived of and without departing from the scope of the present invention, a fender 200 whose fastener 228 comprises a through opening, and whose detachable assembly means 232 would be, for example, disposed on the outer face of the middle portion 234, so that the fastener 228 can assume any position along the length of the arm 222, so as to adapt to frame dimensions 102 reduced relative to those of the frames on which the fender of the present invention may be mounted, the fastener 228 may, by the presence of the through opening, be disposed between the first 224 and second 226 longitudinal ends ales of the arm 222.

As shown in Figures 2, 3 and 4, the first telescopic rod 206 further comprises a locking member 270.

For example and without limitation, the locking member 270 has the shape of a sleeve, mounted on the arm 222 in a sliding manner in the longitudinal direction I of the telescopic rod 206.

The locking member 270 has a through opening 272 sized to receive both a portion of the arm 222 and the adjustment portion 230 of the fastener 228. The locking member 270 includes an inner cover 274 disposed towards the wheel 104 when the mudguard 200 is mounted on the bicycle 100, and an outer cover 276, opposite the inner cover 274.

As shown in the various figures, the inner 274 and outer 276 covers are fixed to each other, so as to constitute a sleeve configured to be slid along the arm 222 in the longitudinal direction I of the telescopic rod 206 .

It will be understood that when the adjustment portion 230 of the fixing piece 228 is engaged in the through opening 272 of the locking member 270, as represented in particular in FIG. 4, the median portion 234 is disposed between the arm 222 and the inner cover 274, the arm 222 then being disposed between the middle portion 234 of the adjustment portion 230 and the outer cover 276.

As shown in particular in FIG. 3, the external face 238 of the middle portion 234 has guide elements consisting of ribs, for example parallel to one another, and arranged in the longitudinal direction I of the rod. telescopic 206, these guide elements being configured to guide the sliding of the locking member 270 around the fastener 228.

In addition, the outer face of the middle portion 234 has, as shown in Figure 4, a projection 278 disposed, for example and without limitation, between the guide elements.

Furthermore, the locking member 270 has a groove 280 formed on the inner cover 274 and dimensioned to receive the projection 278.

It is therefore understood that the blocking member 270 can firstly assume an unlocked position, shown in particular in FIG. 3, in which the blocking member 270 is free to slide along the arm 222, as shown in FIG. the two-headed arrows of FIG. 3, the fastener 228 being disposed, when the blocking 270 is in this unlocked position, outside the locking member 270; in this unlocked position, it is understood that the position of the fastener 228 on the arm 222 can be modified, the fastener 228 can freely be arranged in one of the positions determined by the first 240 and second 248 rack portions previously described. In other words, the position of the fastener 228 is defined by the fact that at least one tooth of the first set of teeth 242, 242 'is disposed between two consecutive teeth of the second set of teeth 250, 250 ', at least one tooth of the second set of teeth 250, 250' then also being between two consecutive teeth of the first set of teeth 242, 242 '.

Alternatively, the blocking member 270 can assume a locked position, represented in particular by FIGS. 2 and 4, in which the fixing piece 228, and more particularly its adjustment portion 230, is engaged in the through opening 272 of 270 to move from the unlocked position to the locked position, after the first 240 and second 248 rack portions have been nested one inside the other, the locking member 270 is slid along arm 222, towards the second longitudinal end 226; by this sliding, the locking member 270 covers the adjustment portion 230 of the fixing piece 228, the locking member 270 and the fastening piece 228 cooperating with each other thanks, in particular, to the elements guidance described above. As shown in particular in FIGS. 3 and 4, the end 231 of the adjustment portion 230 from which the attachment arm 252 extends has a section, considered in a plane transverse to the longitudinal direction I of the telescopic rod 206, greater than the section of the through opening 272, so that the sliding of the locking member 270 along the arm 222 is limited by the end 231 of the adjustment piece 230 of the fastening piece 228. The projection 278 is then engaged in the groove 280, the cooperation of the projection with the groove being facilitated by the formation of a rounded section on the projection 278.

The assembly consisting of the projection 278 and the groove 280 thus constitutes a locking device 279 configured to lock the sliding of the locking member 270 relative to the arm 222; it is also understood that the locking device 279 is also configured to lock the sliding of the locking member 270 relative to the fastener 228.

The locking member 270 is then clipped onto the fastener 228, so that the position of the fastener 228 relative to the arm 222 can not be changed. Indeed, in the locked position of the locking member 270, the fastener 228 can not be displaced transversely with respect to the longitudinal direction I of the telescopic rod 206, the fastener 228 being held against the arm 222 by the locking member 270; furthermore, the fastener 228 can not be moved longitudinally with respect to the arm 222, at least one of the teeth of the first set of teeth 242, 242 'being held between two consecutive teeth of the second set of teeth 250 , 250 '.

The cooperation of the blocking member 270 with the fixing piece 228 thus makes it possible to have the detachable assembly means 232 facing the mounting pad of the frame 102 with which it is configured to cooperate, and, consequently, provides the stability of the assembly of the detachable assembly means 232 of the fixing piece 228, with the mounting pad mounted on the frame of the bicycle 100, in order to avoid any accidental dismounting of the mudguard 200.

It is therefore understood that, in a first step, the locking member 270 is placed in the unlocked position; the user can then move the fastener 228 relative to the arm 222, in order to adjust the length of the telescopic rod 206, by adapting the position of the detachable assembly means 232 to the dimensions of the bicycle whose front wheel 104 is configured to be equipped with the front fender 200. Once the position is reached, the locking member 270 is slid along the arm 222, so as to cover the adjustment portion 230 of the fastener 228, to be arranged in the locked position. The position of the fastener 228 on the arm 222 is then locked, the mudguard 200 is moved so as to engage the mounting stud of the frame 102 in the cavity 260 of the detachable assembly means 232, to allow mounting fender 200 on the frame 102 of the bicycle 100.

Alternatively, the user can, in a first step, engage the mounting pad in the detachable assembly means 232, before moving the arm 222 so as to fit into one another the first 240 and second 248 portions rack, then slide the locking member 270 along the arm 222 to place it in the locked position.

As shown particularly in FIG. 2, when the locking member 270 is in the locked position, it forms a continuity of material with the detachable assembly means 232.

To disassemble the mudguard 200, it is first necessary to pass the locking member 270 from the locked position to the unlocked position; for this purpose, the inner and outer covers 274 and 276 may be spaced from one another, or the adjustment portion 230 may be pushed against the arm 222, by applying pressure on the projection 278, so as to allow the sliding of the locking member 270 along the arm 222, to extract the fixing piece 228, and in particular its adjustment portion 230, from the locking member 270. For example and in a nonlimiting manner, the various elements of the mudguard 200, and more particularly the covers 274, 276 of the locking member 270, will be formed in a plastic material slightly elastically deformable, allowing, among other things, the cooperation by clipping the locking member 270 and the fixing piece 228.

The arm 222 also comprises fastening means 282 mounted on its first end 224, and configured to attach the first end 224 to the protection member 202, and more particularly to the connecting piece 207; for example and without limitation, the fastening means 282 have a pivot axis transverse, or even perpendicular to the longitudinal direction I of the telescopic rod 206, configured to allow the telescopic rod 206 to pivot relative to the protective part 202. The fastening means 282 thus make it easier to mount the mudguard 200 on the frame of the bicycle 100.

For example and in a nonlimiting manner, the fastening means 282 comprise clipping fastening means configured to clip the arm 222 to the protection piece 202.

Furthermore, it is also conceivable, and within the scope of the present invention, fastening means 282, and in particular their pivot axis, configured so that the mudguard 200 can be dismounted without it being necessary to pass the locking member 270 from the locked position to the unlocked position. This embodiment also has the advantage of not changing the length of the telescopic rod 206 during disassembly of the mudguard.

Identically and symmetrically to the first telescopic rod 206 described above, the second telescopic rod 206 'also comprises an arm 222', a fastener 228 ', having a detachable assembly means 232' configured for cooperate with a stud mounted near the front hub 112, the mounting pads configured to cooperate respectively with the detachable assembly means 232, 232 'of the first 206 and second 206' telescopic rods being disposed on either side of the hub before 112.

In addition, the second telescopic rod 206 'also comprises a locking member 270' mounted on the arm 222 'in a sliding manner, and can alternatively take an unlocked position, in which the position of the fastener 228' with respect to the arm 222 'can be modified to adjust the length of the second telescopic rod 206', and a locked position, wherein the locking member 270 'locks the position of the fastener 228' relative to the arm 222 '. The second telescopic rod 206 'also comprises a locking device 279' configured to lock the sliding of the locking member 270 'relative to the arm 222'.

As shown in particular in FIG. 3, the pivot axes around which the detachable assembly means 232, 232 'of the first 206 and second 206' telescopic rods can be pivoted respectively relative to the arms 222, 222 'are parallel to each other. one to another; in particular, the positions of the fasteners 228, 228 'can be adjusted so that the pivot axes of the detachable joining means 232, 232' are aligned with each other.

As shown in particular in Figures 2 and 3, the first mounting means 204 of the front fender includes a base 300 configured to cooperate with a fixing head 302.

The base 300 of the first mounting means 204 is fixed on the outer face 214 of the protection member 202 and has a first 304 and a second 304 'side portions, for example and so non-limiting, arranged parallel to one another, which extend transversely, preferably perpendicularly, relative to the outer face 214 of the protective part 202.

In addition, the base 300 comprises securing means 306 of the base 300 on the protective part 202; for example and without limitation, the securing means 306 comprise a first 308 and a second 308 'rods configured to be engaged respectively in a first 310 and a second 310' openings formed in the outer face 214 of the protective part 202 .

The base 300 also comprises a first 312 and a second 312 'pins, respectively formed on the first and second lateral portions 304, 304', transversely, preferably perpendicular to the plane defined by the lateral portions 304, 304 ', the first and second pins 312, 312 'being directed toward each other and defining a hinge axis.

As shown particularly in FIG. 3, the fixing head 302 has a first 314 and a second 314 'lateral edges, and a first 316 and a second 316' wings, the first and second wings 316, 316 'defining a housing 318 which constitutes a detachable fastening means 320 which will be described in more detail later.

The first and second lateral edges 316, 316 'respectively comprise a first 322 and a second 322' series of orifices, the orifices of the first and second series 322, 322 'being dimensioned so as to respectively receive the first 312 and second 312' pawns of the base 300.

It is understood that when the first and second pins 312, 312 'are respectively engaged in one of the orifices of the first and second series 322, 322', the fixing head 302 can be pivoted relative to the base 300 around the hinge axis defined by the first and second pins 312, 312 '. In addition, the presence of several orifices formed respectively on the first and second lateral edges 314, 314 'of the fixing head 302 makes it possible to move the fixing head 302 with respect to the base 300 in a direction defined by the lateral edges 314, 314 ', and more particularly in a direction transverse to the fastener 202.

As it appears in particular in Figure 3, the orifices formed respectively in the first and second side edges 314, 314 'communicate with each other, a throat being formed between two consecutive orifices. It is therefore understood that the displacement of the fastening head 302 with respect to the base 300 in a direction transverse to the fastening piece 202 may be allowed by a force displacement of the pins 312, 312 'from an orifice to another, the constriction being formed, for example and without limitation, in a slightly elastic plastic material, so as to allow a temporary spacing of the constriction. Alternatively, the pins 312, 312 'may have first and second sides, one of the sides having a length, considered in the plane defined respectively by the first and second 304, 304' side portions, lower than the other side , so that by pivoting the articulated head 302 relative to the base 300, the pins 312, 312 'can be engaged in the constriction formed between two consecutive orifices respectively formed in the first 314 and second 314' side edges.

The first and second wings 316, 316 'are configured to elastically separate from each other so that a part of the frame 102 of the bicycle 100 can be engaged in the housing 320, to fix the first means of mounting 204 to the frame 102 and, more particularly, as shown in Figure 1, on the portion connecting the two branches of the fork 118 to handlebar 110 of the bicycle 100. It is therefore understood that the position of the front mudguard 200 with respect to the frame 102 of the bicycle 100 can be adjusted both angularly, by means of the articulation allowed between the fixing head 302 and the base 300, and transversely, by the presence of two sets of orifices formed on the first and second side edges 314, 314 'of the fixing head 302.

Thus, the front fender 200 has two separate mounting devices, consisting on the one hand by the first mounting means 204 and on the other hand by the first and second telescopic rods 206, 206 ', the two mounting being configured to adapt the position of the mudguard 200 to the dimensions of the frame of the bicycle 100.
