Patent number: 5199664Abstract: A fishing reel having a drag brake is disclosed which has a line receiving pool which is allowed to run free when the drag brake is disengaged. The drag brake is located at an opposite end of the fishing reel housing from the spool and acts on a spindle of the spool at that point. In the vicinity of the spool, a disengageable connection is provided for connecting the spool to a spindle of the fishing reel. The clutch is engaged by rotation of a driving handle. Further provided is an over-run brake located in the vicinity of the spool which acts between the spool and the spindle only upon relative rotation of the spool with respect to the spindle when the drag brake is disengaged. Further included are push rods which, upon displacement, causes disengagement of the spool from the spindle and pawls, carried by a ring surrounding the spindle, which may engage various spaced teeth formed integral with a bush fixed to a rotor of the fishing reel.Type: GrantFiled: February 11, 1991Date of Patent: April 6, 1993Assignee: D.A.M.

Patent number: 5149008Abstract: A spinning reel includes a spool rotatably supported by a spool shaft, a drag member for imparting a braking force to rotation of the spool, and an adjusting member for axially pressing the drag member to thereby adjust the braking force. The spool includes a front face and an annular projection projecting from the front face for preventing water from entering the front face to reach the drag member. The adjusting member is provided with an annular groove for receiving the annular projection.Type: GrantFiled: December 21, 1990Date of Patent: September 22, 1992Assignee: Shimano Industrial Co., Ltd.Inventor: Takeshi Oi

Patent number: 5149007Abstract: A drag mechanism for a spinning reel for fishing, in which a pressure member is provided to push brake plates provided in a spool and is fitted on a spool shaft so that the member can be moved in the axial direction of the shaft; a drag control knob is screw-engaged with the shaft; the front of the pressure member is fitted on the knob so that the knob can be turned relative to the member and the space between the knob and the member is nearly sealed; and an annular spring is fitted to one of the member and the knob in the space so that the bent projecting portion of the spring is engaged with the engaged undulated part of the inside circumferential surface of the other of the member and the knob in the space. According to the above construction, the drag mechanism, especially the drag control knob can be improved in a water-proof property and reduced in size.Type: GrantFiled: August 3, 1990Date of Patent: September 22, 1992Assignee: Daiwa SeikoInventor: Masaji Saito

Patent number: 5121888Abstract: A fishing reel with disengageable spool is disclosed comprising a first groove and a second groove formed in the vicinity of the front end of the spool support shaft. The spool comprises a resilient key engageable in one or other of the first and second grooves. When the spool is engaged in the first groove, a key of the shaft is engaged in a passage in a rear wall of the spool, preventing relative rotation of the spool on the shaft. When the resilient key is engaged in the second groove, the transverse key swivels freely in a space of the spool, allowing the spool to rotate on the shaft. Disengagement of the spool is obtained by axial translation of the spool on the shaft.Type: GrantFiled: August 1, 1990Date of Patent: June 16, 1992Assignee: Mitchell Sports, societe anonymeInventors: Jean Bernard, Joseph Zanon

Patent number: 5120001Abstract: A spinning reel which is for fishing and includes a drag mechanism and a shift mechanism which is for shifting a spool between a drag state and a release state. The reel has a shift mechanism provided between a spool and a spool shaft so that a rotor turning mechanism, a spool sliding mechanism and so forth, which are provided in a casing of the reel, are not restricted. The reel may be provided with a return mechanism by which the shift mechanism can be engaged so that the spool can be shifted from a freely rotating state to a state in which the drag mechanism is engaged.Type: GrantFiled: June 29, 1990Date of Patent: June 9, 1992Assignee: Daiwa Seiko Inc.Inventor: Kyoichi Kaneko

Patent number: 5040743Abstract: A spinning-type fishing reel is provided with a rear-actuated front drag. Concentric shafts are provided with a spool freely rotatable on one shaft. Drag members operate on the spool to provide drag to the spool. A drag knob on the rear of the reel operates on one of the shafts to shift the one shaft axially relative to the other, thereby applying pressure to the drag members and to the spool to increase the drag on the spool. In one form, the spool may be freely rotatable on a spool carrier which is keyed to one of the shafts. A spool cap attached to one of the shafts operates through the drag members to apply drag to the spool. The spool is urged against an abutment carried by the other shaft such that moving one shaft relative to the other by turning the rear-mounted drag knob either increases or decreases the drag on the spool.Type: GrantFiled: April 16, 1990Date of Patent: August 20, 1991Assignee: Zebco CorporationInventors: John A. Zurcher, John W. Chapman, Steven M. Tipton, Richard J. Feehan

Patent number: 5007602Abstract: A click mechanism in a fishing reel is adapted to produce a click sound on relative rotation between a shaft having a first member non-rotatably connected thereto, and a second member which is rotatably mounted on the shaft. The click mechanism comprises a snap-action click ring which is provided between the first member and the second member. First teeth are formed on the side of the first member facing the snap-action click ring. Second teeth are formed on the side of the second member facing the snap-action click ring. The snap-action click ring comprises a first resilient tongue and a second resilient tongue which extend in the same direction in the circumferential direction of the snap-action click ring but are outwardly bent in opposite directions in the axial direction thereof. The first resilient tongue engages the first teeth, and the second resilient tongue engages the second teeth.Type: GrantFiled: March 16, 1990Date of Patent: April 16, 1991Assignee: Abu Garcia Produktion ABInventor: Karl L.
