A spinning reel is provided with a line tension display unit including a display which may be either of analog or digital form. The reel includes a spool shaft for mounting of the spool, the reel body being provided with the line tension/display unit which includes a member swingable about the spool shaft and operatively connected to the spool shaft for swinging movement in response to tension in the line. A torsion spring resists such swinging movement. The swingable member causes the display to indicate the tension value. In analog form, the swingable member provides a pointer for showing line tension on a scale. In digital form, the display includes LED's or LCD's for display of discrete tension values. In one digital version, a microprocessor is used to drive the line tension display and to provide also time-of-day, stopwatch, alarm and line-breakage-warning functions.
In a spinning reel having a reel body and a spool at the front of the reel body for winding of fishing line, a handle extending from the reel body, a flyer, and means for causing rotation of the flyer in response to operation of the handle for winding fishing line about the spool, a spool shaft for mounting of the spool, the improvement comprising a line tension display unit carried by the body including a member swingable about the spool shaft and operatively connected to the spool shaft for swinging movement in response to the tension in the line, spring means for resisting such swing movement, the reel including a drag unit for coupling the spool to the spool shaft, including drag force setting means, the drag unit providing a drag force to permit drag-slippage rotation of the spool upon the line tension exceeding such drag force, and display means comprising a plurality of electronically powered display devices, operative in response to movement of the swinging member about the spool shaft, for displaying values of line tension.
In a spinning reel having a reel body and a spool at the front of the reel body for winding of fishing line, a handle extending from the reel body, a flyer, and means for causing rotation of the flyer in response to operation of the handle for winding fishing line about the spool, a spool shaft for mounting of the spool, the improvement comprising a line tension display unit carried by the body including a member swingable about the spool shaft and operatively connected to the spool shaft for swinging movement in response to the tension in the line, spring means for resisting such swing movement, and display means comprising a plurality of electronically powered display devices, operative in response to movement of the swinging member about the spool shaft, for displaying values of line tension.
In a spinning reel having a reel body and a spool at the front of the reel body, a flyer, and means for causing rotation of the flyer in response to operation of the handle for winding fishing line about the spool, a spool shaft for mounting of the spool, including drag setting control means for setting a preselected drag force to permit drag slippage rotation of the spool upon the line tension exceeding the preselected drag force, the improvement comprising a multifunction display unit carried by the body including a member swingable about the spool shaft and operatively connected to the spool shaft for swinging movement in response to the tension in the line, spring means for resisting such swing movement, and digital display means, including a microprocessor, associated with the swingable member for displaying the value of tension in the line and for displaying also time-indicating functions.
