Description

The technical field of the invention is that of sunshades for motorcycles.

Usually, motorcycles offer no protection against the sun. This is detrimental to both comfort and durability of materials, especially for the saddle. Regarding comfort, the driver is sometimes required to sit on a saddle previously exposed to the sun. The high temperature of the heated seat can be a source of discomfort.

It is known from EP-A1 -1 361 147 a sun visor comprising a roller blind from a winder assembled on or housed in a top box. A first drawback is that not all motorcycles necessarily have a top box. A second disadvantage is that such a blind, once installed, does not allow to maneuver in rotation the handlebar of the motorcycle, for example to activate a steering lock device.

An object of the present invention is a sun visor for a motorcycle, comprising a blind, a winder adapted to wind up said blind, a first end of the blind remaining secured to the winder, a second end of the blind for unwinding the blind, a front fixing means comprising a support adapted to fix the reel, or respectively adapted to hook the second end of the blind, and a rear fixing means comprising a support adapted to hook the second end of the blind, or respectively adapted to fix the retractor, the front fastening means comprising a rotation means, allowing a rotation of the support relative to the front fastening means.

According to another non-limiting feature of the invention, the rotation means further comprises an indexing means in the rest position.

According to another non-limiting feature of the invention, the indexing means comprises at least two ball stops arranged symmetrically on either side of the axis of rotation between the support and the front fixing means.

According to another non-limiting feature of the invention, in the rest position the support is substantially parallel to the front attachment means.

According to another characteristic of the invention, the front attachment means comprises a bar provided at each end with a steerable clip able to be pinched around a mirror rod.

According to another non-limiting feature of the invention, a first end of the bar is assembled to a clamp by a screw / thread device, of axis substantially parallel to the axis of the bar, having a pitch oriented in a first sense, and the second end of the bar is assembled to a clamp by a device screw / thread, axis substantially parallel to the axis of the bar, having a pitch oriented in a second direction, opposite to the first direction.

According to another non-limiting feature of the invention, the winder comprises an elastic return means adapted to automatically wind the blind around the winder, a pull on the second end of the blind, against said elastic return means, allowing unroll the blind.

The front attachment means are advantageously configured to be attached to a part of the handlebar of the motorcycle.

Advantageously, it comprises a system configured to deflect the blind in an area of the intermediate blind between its first end and its second end.

Preferably, the system configured to deflect the blind is arranged so that the blind forms an angle advantageously relative to the larger horizontal between the first end and the area of the intermediate blind that between the area of the intermediate blind and the second end.

According to one embodiment, the system configured to deflect the blind comprises a support member applying on one side of the blind and movably mounted between an extended position and a folded position by hinge means.

The invention also relates to a motorcycle equipped with a sun visor according to the invention.

Advantageously, the motorcycle comprises an axis of rotation of the support relative to the front attachment means which is aligned with the axis of rotation of the guide of the motorcycle.

Other characteristics, details and advantages of the invention will emerge more clearly from the detailed description given below as an indication in relation to drawings in which:

- Figure 1 shows an overall perspective view of a sun visor according to the invention,

FIG. 2 illustrates in perspective a detail of a means of rotation of a support relative to a front fixing means,

FIGS. 3 and 4 illustrate in perspective a fastening clip on a mirror rod,

- Figure 5 illustrates in perspective a means for adjusting the center distance of a front fixing means.

- Figure 6 shows a variant of the embodiment of the other figures. With reference to FIG. 1, a sun visor 1 for a motorcycle, a motorcycle generally designating in the present document any two-wheeled vehicle, comprises a blind 2. This blind 2 is typically made of textile material, suitable for to resist solar radiation, in order to offer the equipment of a motorcycle arranged in its shadow protection against sunstroke, to reduce both the effects of heating and the aging effects, caused by solar radiation. This blind 2 typically has a substantially rectangular shape, elongate along the axis 3 of the motorcycle, of length substantially equal to the length of the motorcycle and of such width that the shade protects the useful parts of the motorcycle against the sun.

Said blind 2 is advantageously deployed, substantially horizontally, above the motorcycle, so that the shadow projected by the blind 2 covers the motorcycle, when said motorcycle is parked. In order to be able to store said blind 2, when the motorcycle is driven, the sun visor 1 advantageously comprises a winder 4 adapted to wind up said textile blind 2, by the width of said rectangle. For this, the textile of the blind 2 is flexible enough to be rolled / unrolled. A first end of the blind 2, corresponding to a width of the rectangle, remains integral with a rotating hub of the winder 4 around which the blind 2 is wound. A second end 5 of the blind 2, corresponding to the other width of the rectangle, is pressed against the reel 4 when the blind 2 is wound, and allows by traction on said second end 5, to unwind the blind 2 to deploy it . The blind 2 deployed, extends and is maintained between firstly the winder 4 to which remains fixed the first end and secondly the second end 5.

To allow deployment and maintenance, the sun visor 1 comprises a front attachment means 6, adapted to be fixed to the front of the motorcycle and a rear fastening means (not shown) adapted to be attached to the rear of the motorcycle. The front fastening means 6 comprises a support 8, while the rear fastening means comprises a support.

Two embodiments are possible here. According to the first embodiment, the winder 4 is disposed permanently in front of the motorcycle, while the second end 5 can be hung, when the blind 2 is deployed removably, at the rear of the motorcycle. According to the second embodiment, the winder 4 is disposed at the rear of the motorcycle almost permanently, while the second end 5 can be hung, when the blind 2 is deployed, removably, in front of the motorcycle. motorcycle.

The support 8 of the front attachment means 6 is thus adapted either to fix the reel 4, in the first embodiment or to hang the second end 5 of the blind 2, in the second embodiment. Similarly, the support of the rear fastening means is thus adapted either to hook the second end 5 of the blind 2, in the first embodiment or to fix the winder 4, in the second embodiment.

According to an important characteristic of the invention, in the first or second embodiments, the front fastening means 6 comprises a means of rotation 10 in order to allow rotation of the support 8 relative to the fastening means 6, around a rotation axis 1 1. Said axis of rotation 1 1 is disposed substantially perpendicular to the elongation of the front fastening means 6. Said axis of rotation 1 1 is still arranged substantially centrally relative to the front fixing means 6. Moreover, as described below the front fixing means 6 is advantageously orientable about its axis. This makes it possible to place the front attachment means 6 relatively to the motorcycle so that the axis of rotation 11 is vertical or more precisely, parallel to the steering axis of the motorcycle. This makes it possible to substantially align the axis of rotation 1 1 with the steering axis of the motorcycle, and thus to allow rotation of the handlebar and the front wheel of the motorcycle, the blind 2 of the sun visor 1 being deployed. This advantageously allows, while leaving the blind 2 deployed, for example to activate or deactivate a steering lock device without risk of deformation of the blind 2, the rotation 1 1 allowing the blind 2 to remain stretched in alignment of axis 3 of the motorcycle.

The rotation means 10 is illustrated in FIG. 1, more particularly in the first embodiment, in which the winder 4 is arranged at the front of the motorcycle on the support 8 of the front attachment means 6. However, both the principle that the advantage obtained by the rotation means 10, are identical in the second embodiment where the support 8 allows the second end 5 to rotate about the axis 1 1 so that the blind 2 remains aligned with the motorcycle without deform.

In both embodiments, the support of the rear attachment means is preferably fixed. It may for example be integral with a top box, the back of a saddle or a rear luggage rack.

In both embodiments, the support 8 hosting the second end 5 advantageously comprises at least two attachment points of said second end 5 of the blind 2. It may be two hooks adapted to accommodate two hooks or two eyelets arranged at the end 5 of the blind 2. It may also be two grommets adapted to accommodate two hooks disposed at the end 5 of the blind 2. Velcro fabric may also be used to make said assembly removably. In the first embodiment, where the second end 5 of the blind 2 is fixed to the rear of the motorcycle, according to a preferred embodiment, the second end 5 of the blind is advantageously shaped or equipped so as to be able to hang on to an element of the motorcycle, without the need for recourse to a rear fastening means and a particular support, the pre-existing element of the motorcycle acting as attachment / support means. An example of such a feature is a second end 5 of the blind 2 equipped with at least one (central) (preferably two side) hook capable of coming to pick the passenger handles, a top box or a rear luggage rack.

FIG. 2 details a front fastening means 6 and the rotation of the support 8 relative to the fastening means 6, thanks to the rotation means 10. Advantageously, the rotation means 10 also comprises an indexing means 12 in the rest position . This makes it possible to immobilize the front support 8 relative to the front attachment means 6, in particular when the blind 2 is not deployed.

Said indexing means 12 comprises, for example, two ball stops 12.

Said ball stops are advantageously arranged, advantageously symmetrically, on either side of the axis of rotation 1 1, either in the support 8 or in the fixing means 6. A thrust bearing cooperates with a hole 12 ' next, in which is positioned a ball. Thus, in the rest position, the front support 8 is immobilized relative to the front attachment means 6. This immobilization can easily be canceled by mobilizing the front support 8 in rotation around the axis of rotation 11, for example by a manual maneuver exerted. on the support 8 or on the element, reel 4 or second end 5, associated with said support 8.

The rest position is such that the front support 8 is substantially aligned with the front attachment means 6.

According to an advantageous embodiment, illustrated in FIG. 1, the front fastening means 6 comprises an elongate piece or bar 13. In order for the front fixing means 6 and the bar 13 to be oriented substantially horizontally and substantially perpendicular to the axis 3 of the motorcycle, said bar 13 is advantageously provided at each of its two ends, a clamp 14, 15.

Each of the two clamps 14, 15 is designed to be clamped around a mirror rod 16, 17. In addition, each of the two clamps 14, 15 is preferably rotatable. Such an arrangement makes it possible to fix said bar 13 between the rods 16, 17 of the two rear-view mirrors of a motorcycle, substantially across the handlebar. The possibility of orientation offered independently by each of the clamps 14, 15, allows each of the clamps 14, 15 to adapt to the orientation, which may be any, of each of the mirror rods, without the need to change the orientation of these rods and thus to find a positioning position of the bar 13 and the front fastening means 4.

Said bar 13, and thus the front fixing means 6, are then found substantially in the middle of the handlebar of the motorcycle. The rotation means 10 is positioned substantially in the middle of the bar 13 and is thus disposed substantially above the steering axis. Thus the rotation 1 1 described above allows the blind 2 to remain deployed independently of a rotation of the handlebar and the front wheel.

Figures 3 and 4 illustrate, in two perspective views, a detail of an illustrative embodiment of such a clamp 14, 15. A clamp 14, 15 comprises two half-shells 18, 19 hollow cylindrically in a substantially diameter. equal to the diameter of a mirror rod 16, 17. The two half-shells 18, 19 are arranged facing one another and around a mirror rod 16, 17. At least two screws 20 allow to tighten one shell 18 against the other 19 so as to grip the rod 16, 17. These two half-shells 18, 19 and their clamping mode allow a translation adjustment along the rod 16, 17 and rotating around of the axis of the rod 16, 17. A fixing device, such as a screw 21 disposed substantially perpendicular to the axis of the rod 16, 17, makes it possible to fix the two half-shells at the end 22, 23 of the the bar 13, while allowing, before the tightening of the screw 21, an additional rotation around the axis of the screw 21. These three degrees of freedom allow a great freedom of positioning of the bar 13 relative to the two mirror rods 16, 17. A tightening of the screws 20, 21 then makes it possible to immobilize the assembly in the retained position.

According to another characteristic, the front fixing means 6 can be adjusted in length, in order to accommodate the distances between mirror rods 16, 17, which are different by varying the distance between the two ends 22, 23 and thus between the two clamps. 14, 15. For this, as illustrated in more detail in FIG. 5, the front attachment means 6 comprises two screw / thread devices 24, 25. A first screw / thread device 24 is disposed between a first end 22 of the bar 13 and the first clamp 14. A second screw / thread device 25 is disposed between a second end 23 of the bar 13 and the second clamp 15. The axes of the two screw / thread devices 24, 25 are aligned and substantially parallel to the axis of the bar 13. The first screw / thread device 24 has not rotating in a first direction, right, respectively left, while the second screw / thread device 25 has a rotating pitch in a second direction. th direction, left, respectively right, said second sense being opposite to the first direction. As a result, a rotation of the bar 13 about its axis of elongation, in one direction, urges the screw / thread devices 24, 25 to increase the length of the bar 13 and thus the authorized distance between the two On the contrary, a rotation of the bar 13 in the opposite direction, urges the screw / thread devices 24, 25 to reduce the length of the bar 13. This allows the attachment means before 6 to adapt at distances between mirror rods 16, 17 different. Advantageously, this adjustment can be performed when the front fastening means 6 is already secured by its clamps 14,15 of one or both mirror rods 16, 17. It is thus possible to configure the front fastening means 6 in situation on the motorcycle, and then block said configuration, by tightening the screws 20, 21 of the clamps 14, 15.

The blind 2 can be wound and unrolled manually on the reel 4. However, advantageously and in known manner, the reel 4 may comprise an elastic return means. Thus the winder is able to automatically wind the blind 2 around the winder 4. A pull on the second end 5 of the blind 2, against said elastic return means, allows unrolling the blind 2 to deploy it. A release of said traction, allows the elastic return means to act and blind 2 to wind around the winder 4.

With reference to FIG. 6, the invention can also be declined with a variant in which a blind deflection system 2 is formed. The remainder of the sun visor may be similar to the embodiment described above, in particular in the design of the rotation means 10. The case of FIG. 6 makes it possible to optimize the position of the blind 2 in an active situation so as to approach it. the area of the motorcycle to be protected, especially the saddle.

For this purpose, the sun visor comprises in this variant a support member 28, for example in the form of a bar transverse to the direction of winding and unwinding. The support member is advantageously configured to be applied on an upper face (opposite to the face facing the saddle) of the blind 2. This application is such that the sheet of the blind 2 is deflected to a intermediate level between the winder 4 and the end 5, so that an angle is formed. From the reel 4, the blind goes down quite steeply, the angle being higher, whereas after the support member 28 the angle is lower, or even horizontal, so as to follow the saddle. It is understood that the support member 28 ensures a lowering of the blind 2 to the nearest motorcycle in its position between the reel 4 and the support member 28. The shape of the support member 28 is not limited to a terminal and, in particular, it may comprise several separate support parts on the blind 2, for example with two tabs each at a lateral edge of the blind 2.

An embodiment of connection between the support member 28 and the remainder of the sun visor is described below: FIG. 6 shows two pairs of arms 26a, 26b, 27a, 27b. The arms 26a, 26b are connected to the remainder of the sun visor, for example at the support 8 of the reel 4, so as to follow the rotational movement. They are pivotally articulated relative to the support 8 to be foldable along the axis of the reel 4, or deployed along the edges of the blind 2.

The arms 27a, 27b are rotatably mounted, at 29a, 29b, at the distal end of the arms 26a, 26b so that the assembly moves in the form of a kinematic compass, according to the transverse arrows of FIG. .

At the other end of the arms 27a, 27b, a pivot connection 30a, 30b makes it possible to bind the support member 28, by its two ends. Optionally, the deflection angle applied may be adjustable, by adjusting the angular position of the arms 26a, 26b in a vertical direction.

Although it is described herein a preferred embodiment of the invention, it should be understood that the invention is not limited to this mode, and that variations can be made within the scope of the invention. scope of the following claims.
