This is earthen wall No. 32,157. This device also includes a rearmost contact element coaxially aligned with the frontmost contact element. However, an elastomeric material is provided on the rearmost contact element, so as to generate a large frictional force against the fishing line. When the fishing line is pulled taut, the rearmost contact element is pressed to close the circuit, thus generating an alarm. Although the operation is significantly simplified, the sensitivity adjustment is only 1, which is inconvenient because it sometimes causes false warnings due to tides, ocean currents, or wind. In addition, this signal generator is not connected to the reel unit. Therefore, attempts must be made to overcome the above-mentioned drawbacks.

It is electrically connected to said alarm means by a conductive element pressed into sliding contact with the side surface.

According to a further aspect of the invention, the sensitivity adjustment means further comprises an elastic element that engages the knob to prevent rotational movement of the knob relative to the first element; The element flexes when the knob is manually operated.

According to still another aspect of the invention, the elastic element is an elastic annular plate that is fitted onto the shaft and abuts the knob, and the elastic annular plate and the knob are engaged with each other. This is a ball and socket connection member that discontinuously restricts rotation.

According to a further aspect of the invention, the stopping means includes a fixed blocking member abutting the two ends of the second contact element, respectively, and an axially movable blocking member, and The axially movable locking member can be driven into tight abutment against the second contact element by screwing a spring-loaded nut on the shaft, and the second contact element can be driven into tight abutment by loosening the nut. can be rotated together with the first element to allow winding and reeling of the fishing line, and further, by screwing the nut, the second contact element can no longer be rotated to actuate the electrical contact means. Can be positioned.

The main object of this invention is to provide a signal generator connected to a reel so that the function of winding and reeling out a fishing line can be easily changed to the function of generating an alarm signal, and vice versa. .

Another object of the invention is to provide a signal device with adjustable sensitivity so that the operation of the electrical contact device is not sensitive to environmental factors, ie, tides, currents, and wind.

It is believed that the above objects and other objects can be made clearer by implementing the preferred embodiments with reference to the accompanying drawings.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the first contact element 20 and the second contact element 19 are coaxially and rotatably mounted on the shaft 5 with one surrounding the other. . Three projections 28 are arranged in an annular manner on the outer surface of the first flange 13, one of which, designated here with the reference numeral 28A, serves as an electrical contact for the first contact element 20.

A 37th flange 16 provided at one end of the second contact element 19
extends outside the first contact element 20 . The rim of the third flange 16 is cut out to form three notches 22 for receiving three protrusions one by one. Third
An insulating board 29 matching the shape of the third flange is mounted on the outer surface of the flange 16 by two bins 21 inserted into two holes 30, respectively. The side surface 1 of the insulating board 29 is fully covered with copper or the like. A conductive plate 32 connected to the side surface 1 coated with metal is connected to one edge portion 2 of the notch 31.
A second portion is located at a location opposite to the projection 28A, and
It serves as an electrical contact for contact element 19. The second contact element 19 is formed from a cylinder, while the first contact element 20 is a reel for winding up a fishing line (not shown). The cylinder 19 consists essentially of three cylindrical segments joined together: a left segment 24, a middle segment 25, and a right segment 26.

The sensitivity adjustment means includes a rotary control knob 41 and a torsion spring member 40 fixed to the control knob 41 at one end. The other end of the torsion spring 40 is fixed to the inner surface of the reel 20. The torsion spring 40 is fitted over the central segment 25 of the cylinder 19 and is held at a constant length between the first shoulder 3 and the control knob 41. To secure the control knob 41 to the right segment 26, a nut 48 may be screwed into the externally threaded portion 27.

As can be seen from the above configuration, when the control ω11 knob 41 is continuously rotated in the direction opposite to the movement of the reel 20 corresponding to the tensioned fishing line, gradually increasing energy is stored in the torsion spring 40. To go. As the energy stored in the torsion spring 40 increases, the sensitivity of the reel 20 decreases. Therefore, by turning the control knob 41, the sensitivity of the rotational movement of the reel 200 can be adjusted to vary the amount of tension on the fishing line caused by fish of different sizes caught on the hook.

An annular elastic element 47 is inserted between the control knob 41 and the nut 48 . Typically, the control knob is an elastic element 47
It is pressed to abut against the second shoulder portion 4 by. When the rotary knob 41 is manually turned with force against the reel 20, the elastic element 47 flexes. By the way, by additionally providing the ball and socket connecting member 49 between the rotary knob 41 and the elastic member 47, it is preferable to discontinuously restrict the rotation of the knob 410 during the corresponding rotation of the M1 contact element. .

The restraining member consists of a fixed blocking member 33 and an axially movable blocking member 43. The movable blocking member 43 is driven into tight abutment against the cylinder 19 by a spring-loaded nut 51.

In cooperation with the fixed blocking member 33, the spring-biased nut 51 is screwed in over ++tb from the cylinder 1.
9 can be positioned in a rotatable position and a fixed position 6r. Winding the fishing line onto the reel 20,
During an operation such as unwinding, the cylinder 19 rotates together with the rotary knob 41 and the reel 20 through engagement between the protrusion 28 and the edge of the notch 31. When using this alarm device, K closes the switch 5 and tightens the spring tension nut 5.
