Description

 Fishing device

The present invention relates to the field of fishing devices and more particularly the field of fishing floats in solidarity with fishing lines and fishing lures reproducing the swimming movement of a live fish for the capture of predatory fish or of marine fish hunters.

In the field of fishing, and more particularly in the field of floating line fishing in the river, it is well known to use a cork float or the like of oblong shape and provided with a vertical antenna projecting from the sea. water surface and immersing in the water when a fish is hooked to the hook of the leader. This type of conventional float is launched in the bed of the river, at a specific location, by means of a fishing rod. However, given the current of the river, it is difficult to keep the float in a certain position. For example, when the wind is blowing in the same direction as the river current, it is difficult or even impossible to control the position of the float, and consequently that of the bait, which then drifts inexorably from the wind and current.

In order to maintain the float and the bait in a determined position, the method of a weight intended to form an anchorage point on the bottom of the river is well known; nevertheless, such a method has a very relative efficiency. Indeed, the fish are likely to identify the weight and refuse the bait. In addition, when the fisherman wishes to move the bait into the river, the latter must get out of the water the bottom of line on which the bait and the weight are mounted, then restart the leader at the new chosen location, risking thus to stoke the vigilance of the fish.

In order to overcome these drawbacks, fishing floats having means for controlling the movement, the maneuverability and the stability of the position of the floats in the stream of a river have already been imagined; this is the case, for example, of British Patent GB 1,397,564 which describes an improved fishing float. This float consists of a thin body obtained in a floating material and whose two faces are flat. The float has at its upper end an upper eye secured to the body of the float by an arm so that said eye upper extends above the waterline of the body, the bottom of the line of the fishing line passing through the upper eye. In addition, the float comprises a second so-called lower eye secured to the lower end of the body and through which the bottom of the line passes. Such a construction provides a fixed angle of the body of the float relative to the direction of the current allowing said body to raise the current when the length of the fishing line is fixed, said length of the fishing line being maintained at a fixed length by locking the reel of the fishing rod for example.

It is known, moreover, the French patent application FR 2,595,542 which describes a fishing line float for static fishing and a dynamic rise of the current of a river. The float consists of a cone-shaped floating body pierced in the middle for the passage of the leader, longitudinally grooved to receive a quadrilateral plate. Said quadrilateral plate is bent in its rear part, pierced at the four corners of its flat part for fixing the four son of determined length, joined at their top to a swivel threaded on the bottom of line of the fishing line. When the fisherman stops the descent of the float in the current by locking the fishing line on the reel, the float rises the current until it reaches a line perpendicular to the axis of the current. These floats have the disadvantage of raising the current in one direction so that, on the one hand, they can be used only from a bank of the river only and on the other hand they have reduced maneuverability.

Moreover, these floats and conventional floats have a volume and an invariable density corresponding to a leaded determined. However, the leaded depends in particular on the bait used or the type of sinned fish so that the fisherman must have several floats of different volumes and densities.

In order to limit the number of floats required for fishing, we have already imagined floats with variable volume and density; this is the case, for example, of the French utility certificate application FR 2 773 435 which describes such a float. This float comprises a hollow tubular element open at both ends, formed of a tubular portion of constant cross section, extended by a neck, of narrower cross-section than that of the tubular section with a constant section, a piston solid element having a through axial bore and adapted to penetrate wholly or partially in a sealed manner in the tubular element or to cover it completely or partially in a sealed manner, and a central rod adapted to be introduced through each end of the tubular element and able to pass through tightly the solid element. Thus by sliding the solid element in the tubular element, the fisherman can vary the volume of air enclosed between the solid element and the tubular element, thus varying the density of the float, to adapt it to the leaded chosen.

Nevertheless, this type of variable density float is difficult to adapt to floats having means for raising the flow of a river, the latter not having a tubular shape.

One of the aims of the invention is thus to remedy these drawbacks by proposing a device for fishing comprising flotation means and means for joining the bottom line of a fishing line making it possible to move said device into the fishing line. River bed, in all directions, using the force of the current.

According to the invention, there is provided a device for fishing comprising flotation means and fastening means at the bottom line of a fishing line consisting of an armament such as a hook for example, and elements ballast such as a lead, a bombette or the like, remarkable in that it consists of a generally flat rigid element, said body, extending substantially vertically in the water in a static equilibrium position and presenting a vertical plane of symmetry orthogonal to the front and rear faces of said body, the rear face being flat, concave or slightly convex and the front face having at least one convex zone whose radius of curvature is less than that of the convexity of the rear face, first guiding means secured to the body above the median plane of the latter and cooperating with the leader to guide the latter perpendicular to the vertical plane of symmetry of said body, and a second guide means extending at the lower end of said body perpendicularly to the vertical plane of symmetry of the body and co-operating with the leader.

Preferably, the first guide means consist of a bead whose ends are secured near the edges of the body of the part and other than its plane of symmetry, the length of the cord being greater than the spacing of the points of attachment of said cord to the body so that said cord extends on the side of the front face of the body, and in a double ring whose first ring is threaded on the cord and the second ring is crossed by the bottom of line. In addition, the second guide means consists of a bar extending from one edge to the other of the body, at its lower end, the bottom line extending between the body and said bar.

In a particularly advantageous manner, the flotation means consist on the one hand in a so-called rear flexible flat or convex wall whose edges are integral with the edges of a recess formed in the rigid body and secondly in a so-called flexible convex wall. front whose edges are secured to the edges of the recess to define between the rear wall and the front wall a volume of air. The rear wall and / or the front wall of the flotation means comprises at least one valve which preferably consists of a frustoconical plug adapted to be introduced into a circular hole formed in the rear wall or before the flotation means, said hole having a diameter generally equal to the average diameter of the frustoconical plug.

Furthermore, the rear wall has a coefficient of elasticity greater than that of the front wall of the flotation means in such a way that, by compressing the front wall towards the rear wall of said flotation means to reduce the volume of air, only the back wall is deformed.

Incidentally, the rear wall and / or the front wall of the flotation means comprises markers corresponding to the weight of the elements of ballast weights. Other advantages and characteristics will emerge more clearly from the following description of several variant embodiments, given by way of non-limiting examples, of the fishing device according to the invention, from the attached drawings in which:

FIG. 1 is a front view of the fishing device according to the invention, FIG. 2 is a side view of the fishing device according to the invention shown in FIG. 1,

FIG. 3 is a front view of the fishing device according to the invention in the static equilibrium position in a river, FIG. 4 is a front view of the fishing device according to the invention moving in a river,

FIG. 5 is a schematic representation of the different movements of a fishing device according to the invention in a river, FIG. 6 is a front view of an alternative embodiment of the fishing device according to the invention,

FIG. 7 is a side view of the variant embodiment of the fishing device according to the invention shown in FIG. 6,

The fishing device according to the invention will be described below in the application of a fishing float intended for fishing in the bed of a river; nevertheless, it will be noted that the fishing device in accordance with the invention may also find application on the one hand as a fishing float on a water without power, said float being displaced by the force of the wind or by a traction exerted by the fisherman who moves along a bank, and on the other hand as a fishing lure reproducing the swimming of a fish, a frog on the surface of the water or a crayfish at the bottom of the water, for example.

With reference to FIGS. 1 and 2, the fishing float according to the invention consists of a generally flat rigid element, said body 1, of oval shape extending substantially vertically in the water in a static equilibrium position and presenting a vertical plane of symmetry S orthogonal to the front and rear faces of said body 1, the rear face 1a being slightly convex and the front face 1b having at least one convex zone whose radius of curvature is less than that of the convexity of the face back 1a. The convex shapes of the rear walls 1a and before 1b are provided by flotation means 2 consisting on the one hand of a so-called flexible convex wall 2a whose edges are integral with the edges of a recess 3 formed in the rigid body 1 and secondly in a so-called flexible convex wall before 2b whose edges are integral with the edges of the recess 3 in order to define between the rear wall and the front wall a volume of air ensuring the buoyancy of the device. The recess 3 of the body 1 has a circular shape centered on the vertical plane of symmetry S of said body 1, the front walls 2b and rear 2a flotation means 2 also having a circular shape. Furthermore, the front wall 2b of the flotation means 2 comprises a valve 4 to allow the entry and exit of air in the volume defined between the front walls 2b and rear 2a. This valve 4 consists of a frustoconical plug 5 adapted to be introduced into a circular hole 6 formed in the front wall 2b of the flotation means 2, said hole 6 having a diameter generally equal to the average diameter of the frustoconical plug 5. By diameter means of the cap 5, the diameter of the latter in its middle part.

The rear wall 2a has a coefficient of elasticity greater than that of the front wall 2b of the buoyancy means 2 in such a way that, by compressing the front wall 2b towards the rear wall 2a of said buoyancy means 2 to reduce the volume of air, after opening the valve 4 only the rear wall 2a deforms. After compressing the front and back walls to reduce the volume of air, the valve 4 is closed. The rear wall 2a is then deformed and then has a concavity, shown in dashed lines in Figure 2. It will be noted that a simple opening of the valve 4 without exerting pressure on the front walls 2b and rear 2a flotation means 2 provides a return to the initial air volume of the flotation means 2, the rear wall 2a returning to its initial convex shape.

In a particularly advantageous manner, the rear walls 2a and 2b before front comprise markers 7 corresponding to the weight of the chosen ballast elements. These marks 7 consist of engraved or printed curvilinear lines whose convexity is oriented towards the upper end of the body 1.

It goes without saying that the body 1 may have an oblong or similar shape and that the recess 3 may have any shape having a plane of symmetry coincident with the vertical plane of symmetry of the body 1, such as an oval shape for example . In addition, it is quite obvious that the rear wall 2a and / or the front wall 2b of the flotation means 2 may comprise several valves 4 and that said valves 4 may consist of any type of valve well known to the man of the art, without departing from the scope of the invention.

It is obvious that such flotation means 2 consisting of at least two walls, a first wall having a coefficient of elasticity greater than that of the second wall, can be applied to any type of fishing float of any shape such as that a conventional oblong hollow float whose wall of the lower part has a coefficient of elasticity greater than that of the wall of the lower part of the float, the wall of the upper part being provided with a valve. These flotation means 2 can thus be applied to floats having no guide means as described in this patent.

Furthermore, the fishing float comprises first guiding means 8 secured to the body 1 above the median plane of the latter and cooperating with the liner 9 to guide the latter perpendicularly to the vertical plane of symmetry S of said body 1, and second guide means 10 extending at the lower end of said body 1 perpendicularly to the vertical plane of symmetry 1 thereof and cooperating with the bottom line 9. Said first guide means 8 consist of a cord 11 whose ends are secured near the edges of the body 1 on either side of its plane of symmetry S, the length of the cord 11 being greater than the spacing of the attachment points of said cord 11 to the body 1 so that said cord 11 extends on the side of the front face 1b of the body 1, and a double ring 12, a first ring 12a is threaded on the cord 11 and the second ring 12b is crossed by the bottom line 9. L e cord 11 comprises on either side of the first ring 12a a sliding stop 13. Each sliding abutment 13 consists of a section of flexible tube whose inner diameter is just equal to the diameter of the bead 11 and whose outer diameter is greater than the inner diameter of the first ring 12a. These sliding stops make it possible to limit the movement of the leader 9 along the cord 11. In addition, the leader 9 has on both sides of the second ring 12b a sliding stop 14 in order to limit the travel of the second ring. 12b along said bottom of line 9. The lower abutment 14 will be referred to as the abutment positioned between the second ring 12b and the plummet and by upper abutment 14 that positioned between the second ring 12b and the fishing rod. Each sliding abutment 14 consists of an oblong bead threaded on the bottom of the line, the hole of the bead having a diameter just equal to the diameter of the bottom of the line 9. The oblong bead consists for example of a "float stop" rubber or elastomer marketed under the trademark "Starbaits" or "Ecopêche" for example. The second guide means 10 consist of a bar 15 extending from one edge to the other of the body 1, at its lower end, the bottom line 9 extending between the body 1 and said 15. This bar 15 is obtained in a semi-rigid wire whose ends are respectively wound around a stud 16 integral with the body 1.

Incidentally, the ends of the cord 11 may be fixed along the edges of the body 1 by passing each of the ends of said cord respectively in a hole 101 and then forming a stop node, such as a node of eight for example, to each said ends. Particularly advantageously, the body 1 may comprise along its edges, near its upper end, a series of holes 101 so that the fisherman can adjust the height of the cord 11 according to the float movement speed desired. It should be noted that the speed of displacement of the float also depends on the speed of the flow of the stream.

Furthermore, it is important to ensure that the bar 15 obtained in a semi-rigid metal wire may in particular be substituted by a sufficiently tight wire without departing from the scope of the invention. In order to allow the fisherman to visualize the position of the float and any catches of fish, said float comprises at the upper end of the body 1 a vertical antenna 17 emerging from the surface of the water. This antenna 17 consists of a vertical parallelepiped 18 provided at its lower end with fastening means cooperating with complementary fastening means of the body 1. The parallelepiped 18 comprises a slot 19 extending, for a determined distance, from its lower transverse face in the direction of its upper transverse face and from a lateral face to the opposite lateral face, said slot 19 having a width just equal to the thickness of the body 1 so that the upper end of the latter is adapted to be introduced into the slot 19 of the antenna 17 so that the longitudinal axis of the parallelepiped antenna 17 coincides with the vertical plane of symmetry S of the body 1. In order to prevent the sliding of the antenna 17 along the edge of the body 1, the latter has at its upper end a vertical groove 20 extending in the vertical plane of symmetry of said body 1 fit receive a parallelepipedal guide 21 having a width just equal to the width of the vertical groove 20 and extending into the slot 19 of the parallelepiped antenna 17 so that the longitudinal axis of the parallelepipedal guide 21 is coincident with the longitudinal axis of the parallelepiped antenna 17. Incidentally, a first longitudinal face of the parallelepipedal antenna 17 is decorated with a first color and the second longitudinal face of the antenna 17 is decorated with a second color, said color preferably being bright colors such as yellow or the red for example, so as to allow the fisherman to know the orientation of the float. We will now explain the operation of the fishing float according to the invention with reference to Figures 3 to 5.

The float is placed in the water, possibly at the edge of the watercourse C (FIG. 5), after having adapted the volume of air contained in the flotation means 2 as a function of the plummet of the bottom of the line 9. note that it is not necessary to launch the float in the middle of the watercourse C. The float tilts slightly with respect to the vertical V forming an angle α as shown in Figure 3. By exerting a pull on the bottom of line 9, by actuating the reel of the fishing rod, for example, the abutment 14 bottom bears on the second ring 12b thus raising the cord 11, the first ring 12a extending to the right of the plane of vertical symmetry S of the body 1 of the float. Said body 1 then pivots until it extends horizontally horizontally, the antenna 17 then being immersed, as shown in FIG. 4, and moves to the right in FIG. 4, that is to say from the left bank to the right bank of the watercourse C, with reference to figure 5, by going upstream of the stream. By releasing the traction of the leader, the float returns to its static equilibrium position as shown in Figure 3 thus allowing static fishing at the place that the fisherman has chosen. By releasing the traction of the leader, then exerting a brief but strong traction on the leader, the abutment 14 below is supported on the second ring 12b thus raising the cord 11 and the first ring 12a slides along the cord 11 until it extends to the left of the vertical plane of symmetry S of the body 1 of the float. Said body 1 then pivots to the left until it extends horizontally horizontally, the antenna 17 then being immersed, in the direction opposite to the direction of the body 1 of the float as shown in FIG. 4, and moves from the left bank to the right bank of the stream, with reference to Figure 5, using stream flow. By adapting the pull of the leader, the fisherman can move the float the other side of the stream while avoiding obstacles such as a strain 22, a bush 23 or a water lily bench 24. It will be observed that by exerting appropriate variations of the traction of the liner 9, the fisherman can immerse almost the entire float thus moving the float under the aforementioned obstacles. Furthermore, it will be noted that, by adjusting the positions and the spacing of the sliding stops 13 of the cord 11, the fisherman can adapt the behavior of the float according to the strength of the current of the stream C and the type of fish that he is fishing. Indeed, the adjustment of these stops 13 allows in particular to adapt the immersion of the float in the water. According to an alternative embodiment of the float according to the invention, with reference to FIGS. 6 and 7, the antenna 17 consists of a rigid planar lamella 25, preferably obtained in a plastic material, provided with fixing means cooperating with means complementary fastening of the body 1 so that said strip 25 extends in the vertical plane of symmetry S of said body 1, at its upper end. Said strip 25 has a wing shape and has a groove 26 adapted to cooperate with a second groove 27 formed at the upper end of the body 1, in its vertical plane of symmetry S, to form a half-timber type assembly . It will be observed that the antenna 17 in the form of lamella 25 avoids total immersion of the float. Indeed, the blade 25 is supported on the surface of the water and provides a force that opposes the rotation of the body of the float when the latter pivots under the action of a pull of the bottom line 9.

It goes without saying that the coverslip may have any shape such as a form of water drop for example and that it is colored, preferably in a bright color. In addition, it goes without saying that the edges of the groove 26 of the strip 25 are able to slide in two grooves extending on the front face and on the rear face of the body 1 in the vertical plane of symmetry S of the latter , the width of the groove being just equal to the distance separating the bottom of the grooves, without departing from the scope of the invention. Finally, it is obvious that the examples which have just been given are only particular illustrations of the fishing device according to the invention and that the examples which have just been described are in no way limiting to the fields application of the invention.
