FR2852488A1 - Fish bite warning device for fishing, has warning light connected to rod support by articulated case and optical fiber for glowing during pulling of wire by fish - Google Patents

Abstract

The device has an articulated case (1) fixed to a rod support (16), an optical fiber (5) and a warning light (4) connected to a wire (15) originating from a reel by an intermediary of wire grip hook (6). The articulation of the case permits tilting rotation of the device with respect to rod support. The warning light connected to the rod support by the case and the fiber glows during pulling of the wire by a fish.

Description

The present invention relates to a light warning device, combining

electronic,

  optical fiber and injected plastic parts, which can be used as a balance key indicator for angling.

  Anglers who use lead fishing, or static bottom fishing, use a visual touch detection system, called a touch indicator squirrel. This indicator is generally secured to the cane support or a stake. The indicator is located under the rod and has a wire clip that holds the wire from the reel. When touched, the pull on the wire caused by the fish generates a vertical or pendulum movement of the indicator. 10 In the case of night fishing, the fishermen associated the indicator with a luminescent rod, which made it possible to visualize the touch despite the darkness.

  The use of this luminescent stick has just been prohibited by a circular from the nuclear safety department due to the harmful radiation emitted by this product. (Decision of the Interministerial Commission on radioelements dated November 23, 1998). 15 The function of this rod being essential for night fishing, we have developed a mechanical device for indicating the touch, comprising an autonomous light source with remote power supply by optical fiber. Switching on the device is made possible by means of a three-position switch, the first position delivering a given level of brightness of 1.26 mA, the second position turning the device off, the third delivering a level given brightness of 4 mA.

  The two energized positions are controlled by a photo-resistor which adjusts the brightness of the device according to the ambient light level and therefore results in savings in energy consumption and battery life. The device according to the invention meets all of these technical constraints. The innovation lies in the fact that this alarm is autonomous with remote power supply by optical fiber.

  The electronics are supplied by a rectangular battery (47mm x 25mm) integrated into the device.

  The device is characterized in that it is made up of both plastic elements - opaque transparent, slightly colored or white plastic body - electronic comprising an electronic circuit for controlling the light-emitting diode with continuous lighting, controlled by photoresistor depending on the light. ambient - and of an optical fiber with diffuse or end-type lighting, as well as the supply battery of the assembly. It is electrically autonomous and hangs on the wire coming out of the reel.

  It is also characterized in that the lighting (five colors to choose from) that it provides is of the diffusing type thus allowing the fisherman to distinguish it over all of the optical fiber and of the plastic body or at the end allowing the fisherman to distinguish only on the plastic body even at very low power. This illumination is obtained by means of a high-brightness diode having a very concentrated beam (Less than 10 'aperture) and an optical fiber.

  The use of high-luminosity diodes allows for equal consumption to have a radiation superior to a conventional light-emitting diode.

  It is also characterized in that the plastic body has two threads at the 10 ends, one allowing the fixing of a wire clamp clip, the second allowing the fixing of the fiber optic connector and the addition of bolts serving as counterweights. to the device.

  It is also characterized in that the plastic housing which contains the electronics, the battery and the fiber optic connector has a hinge allowing pendular rotation of the device. Access to the battery is via a fitted or screwed hatch.

  It is also characterized in that the lighting control of the diode can be carried out by a three-position switch through resistors, controlled by a photoresistor. The associated electronics make it possible to control this illumination in a progressive automatic manner, thus allowing the device to operate at night but also in dark weather. Such an operation gives the device equipped with a single diode, two distinct levels of illumination with an autonomy of more than 437 hours in the case of the first position of the switch delivering at most 1.26 mA, and of a autonomy of approximately 137 hours in the case of the third position of the switch delivering a maximum of 4 mA, with a supply supplied by a rectangular battery type 6 LR 61 of voltage 9v.

  The second position of the switch putting the device off.

  The accompanying drawings illustrate the invention: 1) Figure 1 shows an overview of the device as it is in working order, connected to the rod holder.

  The housing (1) whose body is made of plastic integrates the electronics, a fiber optic connector (13) and the battery (12). The housing (1) has an articulation (3) allowing a pendular rotation 35 of the device, and a specific rail (14) making it possible to separate the housing (1) from the rod support (16). The plastic part (4) which makes up the horn is connected to the housing (1) by means of the optical fiber (5). The line (15) is connected to the horn by means of the wire clip clip (6). When the line (15) is pulled or released by a fish, the horn (4) connected to the rod holder (16) by the housing (1) and the optical fiber (5), goes up or down. The horn (4) is made of transparent opaque colored or white plastic so as to let the light of the optical fiber (5) pass.

  2) Figure 2 shows the device separated from the rod support.

  3) Figure 3 shows the device with the housing (1) separated from its articulation.

  4) FIG. 4 represents the electronic diagram of the device with the three-position switch, and the photo-resistance which controls the level of brightness as a function of the ambient light.

  With reference to these drawings, the device therefore comprises a set of plastic and electronic elements detailed below.

  The plastic parts: The body of the housing (1) is made of opaque injected plastic, it is hollow and has an access hatch which allows the battery to be changed. It houses the electronic circuit and the fiber optic connector (13) and the battery (12). The optical fiber (5) leaves the housing (1) through a sealed opening which is located under the latter.

  On the front face of the housing (1) is an orifice (11) covered with a transparent transparent plastic cover which allows the photoresistor (10) to capture the level of ambient ambient light.

  The upper part of the housing (1) has in its mass a rail (14) which makes it possible to separate it from its articulation (3).

  The horn (4) is made of opaque plastic of different colors or white, it is threaded at both ends to fix the wire clamp clip (6) and the fiber optic connector (7).

  The fiber optic connector (7) is threaded and thus allows the addition of steel bolts (8) serving as a counterweight to the device.

  The electronic part of the device consists of a photo resistor (10), a transistor (18), several resistors (19) and a three-position switch (20). The light-emitting diode (21) is of the high luminosity type with crystal housing equipped with a lens giving it the property of emitting a powerful and concentrated light beam. The discrete components are surface components (CMS).

  The optical fiber part of the device consists of: An optical fiber (5) of the diffusing or end type, connected to the housing (1) and to the horn (4) via the connectors (7 and 13). The connector (7) of the horn (4) has a thread which makes it possible to add or remove steel bolts (8) serving as a counterweight to the device.

  The consumption of the complete device is proportional to the ambient light and thus allows a full performance autonomy of more than 437 hours for the first position of the switch, and approximately 137 hours for the third position of the switch.

  The illumination then decreases as the batteries run down.

  The second position of the switch putting the device completely off.

  The realization of the prototype posed no particular problem. The final device is being manufactured.
