Publication number: 20140158803Abstract: Disclosed herein is a fishing reel having reliability in opening a side cover. The fishing reel is configured such that when the side cover opens, the side cover hangs from the reel body rather than being completely separated from the reel body, so that the user can easily open the side cover even when standing on uneven terrain such as on the rocks of a seashore. The fishing reel has a pillar structure which can conduct a first-extraction and second rotation operation such that even when the reel is designed in such a way that an end of the spool shaft necessarily protrudes out of the reel body, a rotating and opening operation of a cover assembly including the spool cover and the side cover is prevented from be impeded by the shaft, whereby even when in an extreme fishing environment, reliability in opening the side cover can be ensured.Type: ApplicationFiled: December 5, 2013Publication date: June 12, 2014Applicant: DOYO ENGINEERING CO., LTD.Inventor: Kwang-Ho HYUN

Publication number: 20130292504Abstract: Disclosed herein is a fishing reel having a centrifugal brake system. The fishing reel includes a frame, a shaft, a spool and a centrifugal brake system. The centrifugal brake system includes a support member, a plurality of brake shoes, a brake disc and a controller. The support member is provided on one side of the spool and is rotated in conjunction with the spool. The brake shoes are radially coupled to the support member by respective shaft pins. Each brake shoe has a heavy weight part and a light weight part on opposite sides based on the shaft pin to have a weight eccentric structure. When the spool is rotated, the brake shoes are swung by centrifugal force. The controller adjusts a distance between the brake disc and the brake shoes, thus controlling braking power.Type: ApplicationFiled: May 6, 2013Publication date: November 7, 2013Applicant: DOYO ENGINEERING CO., LTD.Inventor: Kwang-Ho HYUN

Patent number: 7938354Abstract: The present invention provides a clutch of a bait reel for fishing which controls rotation of a spool such that only when the handle is rotated to reel in a fishing line can one-way rotation of the spool be restricted. The clutch includes a ratchet wheel which is coupled to a rotating shaft of a handle, and a ratchet pawl which is provided in a reel frame. The ratchet pawl is removably locked to gear teeth of the ratchet wheel to control the rotation of the spool. A separate contact piece made of rigid material is coupled to a contact end of the ratchet pawl. Therefore, the contact piece directly receives a load and frictional resistance occurring when the gear teeth of the ratchet wheel presses the ratchet pawl. Thus, the ratchet pawl which is made of comparatively soft material to facilitate the operation of forming the ratchet pawl can be prevented from being easily damaged.Type: GrantFiled: June 23, 2010Date of Patent: May 10, 2011Assignee: Doyo Engineering Co., Ltd.Inventor: Kwang-Ho Hyun

Patent number: 7374120Abstract: Provided is an anti-backlash apparatus for a bait reel. The apparatus includes a brake shoe holder, a plurality of brake shoes, a stopper, a stopper holder, and locking parts. The brake shoe holder connects to a shaft of a spool. The plurality of brake shoes are radially fitted to the brake shoe holder, move outside, and get friction with a brake ring. The stopper is provided at one side of the brake shoe holder, and restricts movements of the brake shoes. The stopper holder connects to the stopper, and elastically reciprocates and moves left/right by a tension force of the spring. The locking parts are vertically bent at one-side ends of the brake shoes, and are locked at an inner circumference surface of the stopper, and restrict the movement of the brake shoe.Type: GrantFiled: December 18, 2006Date of Patent: May 20, 2008Assignee: Doyo Engineering Co., Ltd.Inventor: Kwang Ho Hyun
