    [0002] Downrigger device for trolling from boat
    [0004] Technique sector.
    [0006] The present invention refers to a downrigger device for trolling from a boat, applicable both in sport and recreational fishing, professional or amateur.
    [0008] Prior state of the art.
    [0010] Trolling is based on dragging a lure attached to a fishing line from a moving boat. Starting from this premise, the advances that have been developed in this fishing technique are basically linked to lures and fishing lines, although lines have not been specifically developed for trolling.
    [0012] In recent years, new products and techniques are being developed to deepen the lure to a certain depth.
    [0014] The most widely used method, ancestrally, is to add weight to the line to sink the lure. Currently this weight is attached to a line parallel to the line, which is moved by electric or manual winches that release or regain the ballast on the line.
    [0016] Devices are also installed to unhook the line from the ballast line in the event that a fish bites, thus facilitating its collection.
    [0018] At present, hydrodynamic plates that submerge are becoming popular thanks to the fact that the line and the plate form an angle with respect to the water surface that causes it to sink due to the hydrodynamic pressure of the water with respect to the plane of displacement, at a greater angle more depth.
    [0020] There is a model that works electronically and uses different sensors to detect the depth at which the lure is. This latest model is the most complete as it allows selecting a specific depth. The other models do not allow to select the depth and to determine the depth, experience and different lures and ballasts are used, combining them with each other, a certain depth is achieved, although it is never constant and will always be affected by speed.
    [0022] In hydrodynamic and ballast plate systems, the depth depends basically on the sailing speed, because the higher the speed, the greater the hydrodynamic drag, which implies a lifting of the lure for the ballast systems and a sinking for the plate systems. This characteristic makes fishing with these systems complicated and inefficient.
    [0024] The method of increasing or reducing the speed of the boat has its limitations because not all species are fished at the same speed and depth. Anglers are not aware of speed, but their attention is on the rod and navigation. Finally, it must be taken into account that you never know how deep the lure is.
    [0026] Other drawbacks are the difficulty of operating the winch while picking up the rod and also the possibility that the two lines become tangled when fishing and the line separates from the ballast line.
    [0028] Trolling is currently divided into surface fishing and deep-sea fishing because different material is used for each modality and even for deep-sea trolling different elements are used depending on the depth to be achieved.
    [0030] Explanation of the invention
    [0032] The deepening device for trolling from a boat, object of the invention, has characteristics aimed at allowing trolling, both surface and deep, keeping the lure at a depth preselected by the user in the device itself,
    [0034] This downrigger device is an underwater vehicle suitable to be dragged from a boat and provided with a submersible body.
    [0036] In accordance with the characteristics contained in claim 1, this device has two control devices, specifically:
    [0038] - an elevator mechanically governed, automatically, by means of a depth selector and a depth compensator mechanism as a function of hydrostatic pressure; and
    [0040] -a rudder adjustable and manually fixable by the user in different positions, according to his preferences for a navigation of the downrig device in a substantially coincident direction or in a direction substantially parallel to the trajectory of the vessel in charge of towing it.
    [0042] The elevator is in charge of raising or lowering the deepening device in the water. Depending on your position and the depth selected for your navigation, the rudder will be actuated to achieve stable navigation at the depth selected by the user.
    [0044] The depth selector comprises a manual operation control integrated in the rotation with an intermediate piece in charge of moving an actuator of the elevator, varying its position when the device reaches the depth preselected with the control, and an axis, connected to a mechanism depth compensator, suitable to be coupled in axial direction and different angular positions with said intermediate piece.
    [0046] The depth compensator mechanism stabilizes the downrigger device at the depth selected with the selector, and comprises: a tight air chamber that is compressed axially by the effect of hydrostatic pressure and actuates a mechanical compensator that transmits a turn to the depth selector shaft proportional to the actual depth of the downrigger device.
    [0048] Each downrigger device is mounted on the fishing line, between the rod and the corresponding lure.
    [0049] Before releasing the downrigger device into the water, select the depth to be navigated by moving the selector knob on the side and once in the water the downrider will maneuver the elevator autonomously to reach and maintain the selected depth .
    [0051] All this process is carried out mechanically and as a sensor to detect depth, a sealed chamber closed at ambient pressure is used.
    [0053] The rudder is manually oriented before the downrigger is placed in the water. Once placed in the correct position it is fixed with a fixing screw so that it does not move while sailing.
    [0055] By properly positioning the respective rudders, several trolling lines can be used in the same boat, with the respective downrigging devices; avoiding that the fishing lines become entangled, as it can happen in the existing systems at the moment.
    [0057] This downrigger device has hooking means to a fishing line composed of: releasable hooks, suitable for uncoupling them from the body of the downrigger device when a fish pulls the line intensely or violently; and a permanent latch that holds the downrigger attached to the fishing line in the event that the releasable latches become disconnected from the downrigger.
    [0059] These and other characteristics of the invention, collected in the claims, will be more easily understood in view of the exemplary embodiment that, by way of illustration and not limitation, is shown in the figures described below:

    [0082] Detailed exposition of embodiments of the invention.
    [0084] The deepening device (1) comprises a submersible body (10), on which the They find externally mounted an elevator (20) located in the front area of the body, a rudder (30) and hooking means (40a, 40b) to a fishing line (L).
    [0086] The body (10) is formed by two lateral half-shells (101, 102) and a removable rear cone (103). The purpose of the body (10) is to contain all the elements and provide a support surface, it also prevents the moving elements from being clogged with elements present in the water.
    [0088] The two half-shells (101, 102) are preferably made of ABS, or similar plastic, and fixed to each other, for example by ultrasound.
    [0090] The body (10) comprises a watertight air chamber (104) at the top, and a ballast chamber (105) below to facilitate vertical buoyancy of the downrigger device.
    [0092] The rear cone (103) has an interior cavity for mounting accessories (not shown), such as cameras, sensors and other elements for recording underwater activity.
    [0094] Said rear cone (103) has at its front end coupling means (106) removable to the body (10), represented in this case by a bayonet-type coupling; and at its rear end an aperture (107) for the camera lens.
    [0096] The elevator (20) has a profile based on the NACA-0012 profiles and its buoyancy is neutral so as not to interfere with navigation stability.
    [0098] The elevator (20) comprises a rudder surface (201), a shaft (202) mounted horizontally in the body (10) and an actuator (203) integral with the shaft (202).
    [0100] Said actuator (203) has a toothed sector (204) for receiving a turning movement controlled by a depth selector (50) and by a depth compensating mechanism (60); and a tail with two stops (205, 206) to limit the inclination of the elevator (20) between two extreme positions of climb and descent.
    [0102] The depth selector (50) allows setting the depth at which the downrigger device (1) is stabilized and comprises: a manually operated control (501) secured to the rotation with an intermediate piece (502) responsible for moving the actuator (203 ) of the elevator (20), varying its position when the device reaches the depth preselected with the control (501), and a shaft (503) connected to the depth compensating mechanism (60) and suitable for coupling in axial direction and different angular positions with the intermediate piece (502) of the depth selector (50).
    [0104] Said intermediate piece (502) has an arm with a toothed sector (509) suitable for engaging with the toothed sector (204) of the elevator actuator (203) and to adjust its position when the depth selected by means of the command ( 501)
    [0106] The shaft (503) and the intermediate piece (502) of the depth selector (50) comprise respective toothed rings (504, 505) complementary, outer and inner respectively, for their axial engagement in different relative angular positions.
    [0108] To be able to select a specific depth, the toothed crowns (504, 505) are disengaged by moving the knob (501) and the intermediate piece (502) towards the outside of the body (10) and once the desired depth has been selected on a scale existing in the body (10), the aforementioned toothed rings (504, 505) are reattached by moving the knob (501) and the intermediate piece (502) in the opposite direction, that is to say towards the inside of the body (10).
    [0110] The shaft (503) of the depth selector (50) comprises a pinion (506) to receive a movement of the depth compensating mechanism (60) and transmit it to said depth selector
    [0112] The shaft (503) and the intermediate piece (502) have sectors (507, 508) on axially facing surfaces that prevent the coupling of the respective crowns (504, 505) in a portion of the selector path where no depth can be selected; the depth selection zone being about 295 °.
    [0114] The depth compensating mechanism (60) in charge of stabilizing the downrigger device (1) at the depth chosen with the depth selector (50), comprises: a sealed chamber (601) of air that is axially compressed by the effect of hydrostatic pressure ; A first rack (605) moves axially when the watertight chamber (601) contracts under the action of hydrostatic pressure and operates a mechanical compensator (606) that transmits a proportional rotation to the shaft (503) of the depth selector (50) to the actual depth of the downrigger.
    [0116] Said watertight chamber (601) is made of latex, silicone, or any other similar material that resists corrosion by salt water and has an accordion-like configuration to facilitate linear contraction and the walls do not deform as the pressure increases. Pressure.
    [0118] Said watertight chamber (601) is sealed at its ends by means of a first watertight closure (602) fixed to the body (10) of the downrigger device, and a second watertight closure (603) provided with lateral appendages (604) that can be moved longitudinally. along longitudinal guides (108) defined inside the body (10), which allows said watertight chamber (601) to contract, reducing its length due to the effect of hydrostatic pressure when the deepening device is submerged in the Water.
    [0120] The second closure (603) of the sealed chamber (601) is fixed to a first rack (605) that moves axially when the sealed chamber (601) contracts under the action of hydrostatic pressure.
    [0122] Said first rack (605) actuates a mechanical compensator (606) that transmits to the shaft (503) of the depth selector (50) a rotation proportional to the real depth of the downrigger device.
    [0123] The purpose of the mechanical compensator (606) is to facilitate a precise depth selection even at great depths, and to stabilize the downrigger device at the depth chosen by the depth selector, since the shrinkage of the watertight chamber (601) does not vary from uniform mode and proportional to the depth of immersion.
    [0125] Said mechanical compensator (606) comprises a wheel (607) provided with: - a toothed shaft (608) that rotates by the action of the first rack (605) connected to the movable end of the watertight chamber (601) and, - a slot curve (609) of variable geometry that transforms the rotation of the wheel (607, caused by the contraction of the sealed chamber (601), into a longitudinal movement of a second rack (610) coupled to the pinion (506) of the gear selector shaft depth (50), said longitudinal displacement being proportional to the variation in hydrostatic pressure on the watertight chamber (601) of the downrigger device.
    [0127] The geometry of the curved groove (609) is calculated from Boyle's law on gases: V1 * P1 = V2 * P2, the depth compensating mechanism ensuring that the linear displacement of the second rack (610) is proportional to the immersion depth of the downrigger.
    [0129] The aforementioned rudder (30) comprises two blades (301, 302) mounted on respective half shafts (303, 304), arranged on opposite sides of the body and independently adjustable manually, with the same or different inclination and which are fixed in the positions chosen by means of a fixing screw (305) that radially presses some end stops of the semi-shafts (303, 304).
    [0131] The main function of the rudder (30) is to roll to keep the device straight or to cause it to roll to the right or left depending on the needs of the fisherman.
    [0133] The movement of the blades (301) of the rudder (30) is carried out by hand and each user determines how they use said rudder. If you fix the two blades (301, 302) with the same inclination, up or down, the downrigger device (1) does not tilt laterally and acts as a reinforcement for the elevator. If the two blades are centered (at 0 °) they do not affect the navigation of the device downrigger. If one of the blades is oriented upwards and the other downwards, the rudder causes the downrigger device (1) to warp and to move in an oblique direction, towards one or the other side.
    [0135] The downrigger device comprises means of hooking to the fishing line (L) that includes at least one releasable hook (40a) and a permanent hook (40b).
    [0137] Each releasable hook (40a) comprises a ring (401) for passing the fishing line (L) provided with a pin (402) arranged between the body (10) of the downrigger device (1) and a clamping piece (403) , and a clamping screw (404) that presses the body (10) and the clamping piece (403) against the pin (402) of the ring (401) making their fixation.
    [0139] In the example shown, the downrigger device comprises two releasable hooks (40a) fixed in the upper zone of the body (10).
    [0141] Said releasable hooks (40a) make it possible to disconnect the deepening device from the fishing line (L) to avoid damage in the event that a catch violently shakes said line (L) or line.
    [0143] As the line is hooked directly to the piece, when a fish pulls the bait with enough force, the downrigger device (1) may hit the seabed or the fish itself and if the downrigger device were firmly attached to the line, it would absorb all the force of the impact.
    [0145] The resistance to disengagement of the releasable hooking means (40a) is conditioned by the pressure exerted by the clamping screw (404). The greater the tightening of the screw, the more force will be needed to release these hooks.
    [0147] When the downrigger device receives a pull from the fish with a force greater than the tensile strength of the releasable hooks (40a), they pivot backwards and the pins (402) carrying the rings (401) are released from the pieces of clamping (403).
    [0148] In the event that the releasable hooks (40a) are disengaged from the downrigger device (1), the downrigger device remains attached to the fishing line (L) or line by means of the permanent hook (40b) that comprises a ring (405) of passage of the fishing line (L), attached to the body (10) by a front safety cable (406)
    [0150] Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential characteristics of the invention that are claimed below.
