Description

FIELD OF THE INVENTION The invention relates to a float for angling, in particular a float intended to be mounted on the line of a fishing rod. State of the art Floats are commonly used for angling, and have not undergone major improvements since the 1950s. Depending on the type of fishing, they can be configured to float on the surface of a fishing boat. liquid or serve as ballast. Floats of the Buldo brand are frequently used for angling. These comprise for example a hollow sphere provided on the one hand with two rings for attaching the fishing line, and on the other hand two plugs closing two holes of the sphere. Through the holes, the user can insert a greater or lesser amount of liquid to adapt the mass of the float to his needs. The float, however, can not fill itself by simply being soaked in the liquid because the holes are very small. The user is forced to press the float to enter the liquid, and force the sphere to fill. In addition, the surface of the sphere is generally smooth, and the float tends to sink under the waves, which limits its movement on the surface and does not encourage the fish to attack the bait. In order to encourage the fish to take the bait, the user must generally move the float by bringing it back to him using a reel. The user must thus make several launches of the float, which tends to scare the fish.

Other types of float used can for example be based on the teaching of patent FR 1029714, which discloses a float comprising two compartments, the first being provided with one or more orifices remaining permanently open and inside which water can freely enter, while the second is watertight and filled with air. The float further comprises two rings for attaching the float to the fishing line by a system of nodes. Due to its structure, the float of the patent FR 1029714 lies partly beneath the surface of the water. It is impossible to float completely because of the first compartment filled with water, which makes it difficult to see. In addition, the resistance of the float to immersion in water - due to the volume of air contained in the second compartment - limits the fishing yield. Indeed, the fish are timid and tend to release the bait hooked at the end of the line when the float offers resistance to immersion in water.

Resistance to immersion also causes a lack of versatility of the float. In fact, the fisherman can not fish on the surface and then at depth without modifying the fishing line, he must for example add pellets on the bottom of the line.

Finally, the means for attaching the float to the fishing line are such that the line must often be cut to release the float when it is no longer used.

OBJECT OF THE INVENTION The object of the invention is to remedy the aforementioned drawbacks, and in particular to provide a float for line fishing which can float for a surface fishing, and which offers little resistance to immersion. in water. Another object of the invention is to provide a light float that can be moved on the surface of the water under the effect of the current or the wind, in order to give an undulatory movement to the bait and thus to improve fishing. area. The float comprises a hollow body forming a main cavity provided with attachment means for attaching the hollow body to the line, and further comprises a wall of lower density than the liquid and extending along the main cavity. The main cavity is further disposed below the liquid surface, and is configured to have a first flow resistance in a first direction, the first resistance being different from a second flow resistance of the main cavity in a first direction. second direction opposite the first direction. Thus, there is provided a float configured to "surf" on the surface of the water, that is to say be carried by the waves under the effect of the current or wind. In addition, when the float rises or falls on the waves, it animates the bait with a movement from top to bottom, which improves the catch of the bait. According to one aspect of the invention, the wall of the float is substantially flat.

Furthermore, the body may comprise a surface in which the opening is located, the surface having a shape of a half-ellipsoid and delimiting, with the wall, the main cavity.

The opening may include a valve movably mounted on the body between an open position to allow the insertion of a ballast into the main cavity, and a closed position to retain the ballast in the main cavity. The opening is located on the valve to allow the liquid to and fro in the main cavity, and the valve further comprises a retaining element for retaining the ballast in the main cavity. The float may also include locating means such as a visible light reflecting element, or a complementary surface which forms with the body surface a shell having an ellipsoid shape. If the float has a complementary surface, then the complementary surface forms with the wall an additional cavity, and the complementary surface advantageously comprises at least one hole to allow the passage of liquid or air in the additional cavity. According to one embodiment, the attachment means of the line comprise a tube formed in the wall and extending along the main cavity, and locking means cooperating with the tube to block the line in the tube. As an alternative to the locking means, other embodiments make it possible to attach the float to the line, while allowing the float to be translated along the line. This allows the float to continue to float when the fish catches the bait and pulls on the line.

For example, the body may comprise a tube through which the line passes, the tube opening on a housing for accommodating a removable hook around which part of the line is wound. These attachment means also have the advantage of being able to easily adjust the length between one end of the line and the float. Alternatively, the wall may include a groove for housing the line, the groove extending along the body of the float and being open towards the additional cavity. The complementary surface is provided with a slot opening at a first end outside the body, and at a second end in the groove, the float further comprising a rod provided with a fin, the rod being configured to fit into the groove and allow a translation of the line in the groove, while the fin is introduced into the slot to maintain the rod in the groove. When the float is used as ballast, it is no longer possible to locate it. In this case, the float advantageously comprises a signal plug outside the body of the float and having an additional groove for receiving the line, and an additional slot open to the outside and opening into the additional groove. The float further comprises an additional rod provided with an additional fin, the additional rod being configured to be introduced into the additional groove, and allow a translation of the line in the additional groove, the additional fin being introduced into the slot additional to maintain the additional rod in the additional groove. In this embodiment of the float, the position of the fishing line is still visible through the signal cap when the fish dead hook, and pulls on the line so as to immerse the body of the float.

DETAILED DESCRIPTION FIG. 1 shows a fishing float mounted on a line 11. The line 11 has an end commonly called "bottom of line", on which is fixed a hook 12 for retaining a bait. 6. The float can be used for different types of fishing: surface fishing and deep-sea fishing. In Figure 1, the float is shown in the floating position on a liquid when used in the context of surface fishing. The liquid can be a river, a lake, a restless or calm body of water, etc. FIG. 1 represents the float comprising a hollow body 1 provided with a main cavity 2 delimited by a surface 3, and a wall 4. The wall 4 preferably has a substantially flat shape and extending along the surface 3 (FIG. see Fig. 3), so that the hollow body 1 preferably has a half-ellipsoid shape. The surface 3 has the particularity of having at least one permanent opening 5 advantageously at one of its ends to first fill the main cavity with water, and secondly to allow the back and forth of the when the float is used. According to the embodiment illustrated in FIG. 1, the float comprises locating means comprising a complementary surface 8 mounted on the wall 4, so as to advantageously form an additional cavity 9. The shape of the additional cavity 9 is similar to that of the main cavity 2, so that the body surface of the float 1 is a shell having an ellipsoid shape.

The surface 8 is provided with holes 10, to allow the passage of water or air through the additional cavity 9. Thus, when the surface of the water is subjected to disturbances (wind, current, etc.). ), water or air can pass through the float 1 instead of passing over the latter, which avoids the immersion of the float 1.

Advantageously, the holes 10 are regularly distributed to have an equivalent behavior irrespective of the direction of the disturbance. The float preferably comprises a channel 13 passing through the float along a longitudinal axis and configured to let the line circulate. In a particular embodiment, the channel 13 is a groove formed in the complementary surface 8. This configuration facilitates the insertion and extraction of the line in the channel 13 without having to disassemble the line. Advantageously, the line 11 is held in the groove 13 (see FIG 8a) using a rod 15 having a shape configured to close the groove 13 while leaving a free portion, for a part prevent the line 11 from leaving the groove 13, and secondly allow the translation of the float 1 along the line 11. As illustrated in Figure 8c, the groove has a cylindrical inner portion which is partially closed by the rod 15 shaped half-cylinder to close the insertion and extraction zone of the line 11. The rod 15 is also advantageously configured to be inserted into the channel from one end of the channel along the longitudinal axis.

Figures 2 and 3 show a particular embodiment of the invention, wherein the float comprises only the hollow body 1. It should be noted that all the openings 5 are preferably placed on the same side to allow the filling of the main cavity 2. Indeed before launching the float, the user fills it on average to one third of its volume but it can fill it more if the float must be launched very far. It is therefore important that the openings 5 are located at one end of the hollow body 1, otherwise the water flows before the float is launched. Furthermore, the opening or openings 5 are arranged to create two different flow resistances in two opposite directions of transit of the liquid. On the side where the openings 5 are, the resistance to the flow of the liquid is low since the water can freely enter and exit the cavity 2. In contrast, on the opposite side to the openings 5, the resistance to the flow is high since liquid must necessarily flow along the hollow body 1. Thus, the movement of back and forth of the liquid is reflected by two different movements of the float, which is particularly interesting for the bait to be tempting for fish. This resistance to the flow which is asymmetrical provides a certain advantage when the float is used: the displacement of the float in the water is improved in case of wind or current, because the water which enters and leaves freely of the cavity 2 can easily move the float. Thus the bait 6 attached to the hook 12 located at the bottom of the line 11 is more mobile and the fish is more prone to attack.

Similar operation can be achieved by placing one or more small openings at one end of the float, and placing the openings 5 at the other end of the float. This configuration also induces an imbalance of the flow inside the main cavity 2.30 Moreover, the wall 4 is advantageously configured to allow the floating of the float on the water. In this case, it is made of a material of lower density than the material in which the surface 3 is formed. The wall 4 is for example a polystyrene, cork or foam plate. The wall 4 may also define a cavity filled with air or another material. Furthermore, the surface 3 and the wall 4 are sized so that the buoyancy of Archimedes is lower on the surface 3 than on the wall 4.

The combination of the densities and dimensions of the surface 3 and the wall 4 thus allows the float to be held horizontally, so that the surface 3 of the hollow body 1 remains under the wall 4 and under the surface of the liquid .

With this type of structure, it is possible that the float is hardly visible when it is launched far, or when the surface of the water is subjected to disturbances. To remedy this problem, another embodiment of the float can be used, in which locating means are added. This is for example a visible light reflective element, such as an aluminum film that can be mounted directly on the wall 4. In this way, thanks to the light reflections, it is much easier to visualize the place where is the float.

In an alternative embodiment shown in FIGS. 4 and 5, the float identification means comprise the complementary surface 8 mounted on the wall 4 and forming the additional cavity 9. The holes 10 formed on the complementary surface allow the passage of water or of air, so that the float remains visible even if the surface of the water is agitated. Indeed, if the holes 10 did not exist, the water would pass over the float in case of wave, so that the user could no longer view the float. The fact of placing tracking means on the float indirectly makes it possible to increase the fishing yield. Indeed the user, who sees the float at any time, is almost certain that the fish has attacked if the float begins to deviate from its trajectory. He can react by ironing the fish.

Note that the fact of introducing holes 10 on the additional cavity 9 also limits the buoyancy of Archimedes when the float is immersed in water. This is particularly advantageous when the fish catches the bait 6 and drives the float deep. The immersion of the float is not subject to great resistance, and the fish is not wary. The configuration of the float used as ballast is slightly different from that previously described, and is shown in Figures 6 and 7.

To be able to easily ballast the float, it is necessary to insert in the main cavity 2 elements preferably having a higher density than water, such as pieces of lead (not shown). These elements must be large enough not to exit unexpectedly through the openings 5 of the cavity 2 when the float is in the water. A fortiori, they can not be inserted into the cavity 2 through the openings 5. It is therefore necessary to provide a valve 17 larger than the openings 5, and may have open and closed positions. In this embodiment shown for illustrative purposes, the valve 17 can pivot relative to the rest of the float with a hinge, and close with the help of clips (not shown). For the sake of maneuverability, gripping lugs 18 may also be arranged on either side of the valve 17. Alternatively, it is possible to place the openings 5 on the valve 17, and to position the assembly to the one of the ends of the additional cavity 2. FIGS. 8a, 8b and 8c show a particular embodiment of the means for attaching the line to the float. Here, the float is removably mounted to remain on the surface of the water when the fish catches the bait 6 and pulls on the line 11. This embodiment can be combined with the previous. In this embodiment, the line 11 is housed in a groove 13 located on the wall 4 and extending along the body of the float, that is to say the through from one side. The groove 13 is advantageously located along an axis of revolution of the float, so that the wall 4 comprises two identical half-plates extending on either side of the groove 13.

Furthermore, the complementary surface 8 is provided with a slot 14 opening at one end towards the outside of the float, and opening at the other end in the groove 13. As indicated above, the role of the slot 14 is to facilitate the insertion of line 11.

More generally, the slot 14 could very well be located in a plane of symmetry of the main cavity 2 or the additional cavity 9, or in any other plane provided that it is different from the plane of the wall 4 Indeed, forming the slot in the plane of the wall 4 would change the amount of material of a large part of the wall, and this could lead to an imbalance of the float that would no longer fulfill its function properly.

The line 11 is held in the groove 13 by means of the rod 15 provided with a fin 16 having a shape similar to that of the slot 14. In this embodiment, the rod 15 has the shape of a half cylinder-on the one hand to prevent the line 11 out of the groove 13, and secondly allow the translation of the float along the line 11. The width of the fin 16 is also slightly lower than that of the slot 14, and the width of the rod 15 is very slightly less than the width of the groove 13. In this way the friction forces between, on the one hand, the slot 14 and the fin 16, and on the other hand part of the groove 13 and the rod 15, are sufficient to prevent the rod 15 from leaving the groove 13. Alternatively, the line 11 can be inserted into a tube 7 formed in the wall 4 and passing through the body of the float from in part. At the end of the tube is then a housing 25 formed in the hollow body 1 and in the complementary surface 8, and configured to accommodate a hook 24. This embodiment is shown in Figure 9.

To mount the float on the line 11, the user inserts the line 11 in the tube 7, then attaches the line 11 to the hook 24. The shape of the hook 24 is judiciously chosen so as not to need to make knots for the to attach.

This type of attachment also has another advantage: by attaching the line 11 to the hook 24, and not directly to the body of the float, it is possible to change float at any time. In this embodiment of the float, when the fish catches the bait 6 and pulls on the line 11, the hook 24 leaves the housing 25 and is driven with the line 11, while the float remains in the floating position, and remains visible to the user. Other means of attachment of the line 11 to the float can be used, it is fixed fastening means. In a conventional manner (embodiment not shown), the line 11 can be inserted into a tube formed in the wall 4 and passing through the body of the float 1 from one side. To fix the line 11 to the float, blocking means can be used. One can choose for example a rod having the property of being hollow and having fixing holes. The line 11 is then inserted into the rod and knotted to the fixing holes, and the rod is then inserted into the tube to block the line 11.

Alternatively, the float may comprise one or more rings to hang the line 11. During its use as ballast, the float may be difficult to see by the user even if it is provided with tracking means. To remedy this problem, the float comprises for example an additional element such as a signal plug 19, which is external to the body of the float. In the embodiment illustrated in FIGS. 10a and 10b, the signaling plug 19 is a sphere having an additional slot 20 open towards the outside to facilitate the insertion of the line 11, and opening into an additional groove 21 advantageously located next an axis of revolution of the signaling plug 19.

The fishing line 11 is held in the additional groove 21 with the aid of an additional rod 22 provided with an additional fin 23, the shape of the additional rod 22 being adapted so that the signaling plug 19 can slide along line 11, as indicated above for the float.

The additional rod 22 and the additional groove 21 have friction properties similar to those of the rod 15 and the groove 13. Similarly, the additional fin 23 and the additional slot 20 have coefficients of friction similar to those of the fin 16 and slot 14.

In this embodiment, if the fish catches the bait 6 and pulls on the line 11, the signaling plug 19 slides along the line 11 and remains on the surface of the water. The user can then realize that he has a catch, for example when the signaling cap 19 changes course suddenly.

Thus, there is provided a simple device to achieve, efficient in terms of yield, and suitable for all types of fishing.
