Patent number: 9808940Abstract: A folding knife includes a handle having a pivot axis, a blade attached to the handle, a movable member that moves about the pivot axis, an urging spring, and a switching mechanism. The movable member has an engaging claw. When the blade is in a folded position, the switching mechanism holds the movable member in a disengaged state, in which the engaging claw is disengaged from an engaging portion of the blade. When the blade moves from the folded position to the switching position, the switching mechanism switches the movable member from the disengaged state to an engaged state, in which the engaging claw is engaged with the engaging portion, thereby moving the movable member in the open direction by the urging spring to move the blade from the switching position toward the open position by the movable member.Type: GrantFiled: July 28, 2016Date of Patent: November 7, 2017Assignee: GERBER SAKAI CO., LTD.Inventor: Kimiyuki Sakai

Patent number: 8832943Abstract: Retractable scissors include a holder and a scissor piece mounted on the holder. The scissor piece is rotational with respect to the holder among a closed position, at which the scissor piece is retracted in the holder, a first open position, at which the scissor piece is open with respect to the holder at an acute angle, and a second open position, at which the scissor piece is open with respect to the holder wider than at the first open position. The scissor piece includes a first edge, and the holder includes a second edge that intersects and contacts the first edge. When the scissor piece is rotated with respect to the holder from the first open position toward the closed position, the scissor piece and the holder cooperate to function as a pair of scissors that cuts an object between the first and second edges. When the scissor piece is located at the second open position, the scissor piece functions as a blade of a knife, and the holder functions as a handle of the knife.Type: GrantFiled: June 26, 2012Date of Patent: September 16, 2014Assignee: Gerber Sakai Co., Ltd.Inventor: Kimiyuki Sakai

Publication number: 20100192381Abstract: A folding knife includes a handle and a blade pivotally supported on the handle. A tang of the blade includes a cam surface. The cam surface has a substantially arcuate guiding portion and an engagement portion that is formed continuously from one end of the guiding portion. The handle has a blade locking mechanism. The locking mechanism includes a slider and a coil spring that biases the slider. The slider is movable along the longitudinal direction of the handle between a lock position, at which the slider is engaged with the engagement portion, and an unlock position, at which the slider is separate from the engagement portion. The slider has a pressing portion that is engaged with the blade when the blade is arranged at the folded position. By moving the slider in the direction from the lock position toward the unlock position when the blade is at the folded position, the pressing portion presses the blade out of the folded position toward the open position.Type: ApplicationFiled: February 2, 2009Publication date: August 5, 2010Applicant: GERBER SAKAI CO., LTD.Inventor: Kimiyuki Sakai

Patent number: 6836967Abstract: A folding knife includes a handle and a blade pivotally supported on the handle. A tang of the blade includes a cam surface. The cam surface has a substantially arcuate guiding portion and an engaging portion that extends continuously from one end of the guiding portion. A notch formed on an upper edge of the handle is provided with a lock mechanism. The lock mechanism includes a guide member, which is fixed to the handle in the notch, a hollow lock tube, which is supported on the guide member, and a coil spring, which is accommodated in the lock tube. The lock tube is movable along the longitudinal direction of the handle between a lock position for engaging the engaging portion and an unlock position separated from the engaging portion. When the blade is in the open position, the coil spring moves the lock tube toward the lock position. Thus, the blade is securely locked in the open position.Type: GrantFiled: December 30, 2003Date of Patent: January 4, 2005Assignee: Gerber Sakai Co., Ltd.Inventor: Yoshiro Sakai

Patent number: 5450670Abstract: A knife is provided having a blade, foldably supported by a handle, and a hook for fastening the knife onto another object apart from the knife. A pair of brackets are integrally and flexibly formed with the handle to pivotably attach the base of the hook to the handle. The brackets are given flexibility as a result of being resin-molded integrally with the handle. The hook has a base which is directly attached to the brackets, and a body which is hooked onto an object. Both brackets have a pair of bearing holes lying on the same axis. The base of the hook also has a pair of support shafts which are rotatably fit into both the bearing holes. The hook can then be pivotably attached to both brackets by fitting both support shafts into both bearing holes.Type: GrantFiled: June 7, 1994Date of Patent: September 19, 1995Assignee: Gerber Sakai Co., Ltd.Inventor: Kimiyuki Sakai
