Patent number: 11161260Abstract: A knife has a first part and a second part movably engaged to the first part along a path between an open position in which a housing interior is accessible and a closed position. A holding surface is fixed on and jointly slidable with the second part, and a third part is fixable on the first part, An actuator is movable on the second part between an actuated position and an unactuated position. An arm integral with or fixed on the third part is operatively engaged by the actuator and displaced on movement of the actuator between the unactuated position and the actuated position between a locking position securing the second part in one of the open and closed positions and a release position.Type: GrantFiled: October 2, 2013Date of Patent: November 2, 2021Assignee: MARTOR KGInventors: Peter Schekalla, Martin Herlitz, Martin Rohrbach

Patent number: 10814505Abstract: A knife with automatic blade retraction including a housing, a moveable actuating device, a rotatable blade unit, and a retraction element which always applies a retraction force to the blade unit in the direction of the retracted position. The rotatable blade unit can be brought into engagement with the actuating device and is moveable by means of the actuating device from a position retracted in the housing into a position extended from the housing. The blade unit is also rotatable by the action of a cutting force in an extended position from an engagement position in which the blade unit is in engagement with the actuating device into a release position in which the blade unit is not in engagement with the actuating device.Type: GrantFiled: September 25, 2018Date of Patent: October 27, 2020Assignee: MARTOR KGInventor: Peter Schekalla

Patent number: 9770833Abstract: The invention relates to a knife including a housing (11) inside which a blade holder (15) is movably mounted. The blade holder (15) comprises a main part (17) and least one holding part (18) which is movable between a holding position and a in replacement position. In the holding position, a blade (16) can be tightly retained in a replaceable manner in a blade seat between a first holding surface (46) of the main part (17) and a second holding surface (45) of the holding part (18), while in the replacement position, the blade (16) can be removed from the blade seat or a new blade can be mounted in the blade seat. The invention is characterized in that in at least one relative position of the blade holder (15) to the housing (11), the blade holder (15) is biased against a stop (21) by a restoring force, and in that the holding part (18) can be moved into the blade replacement position by having an abutment surface (24) on the stop (21) cooperate with a mating surface (25) on the blade holder (15).Type: GrantFiled: October 2, 2013Date of Patent: September 26, 2017Assignee: MARTOR KGInventors: Peter Schekalla, Martin Herlitz, Martin Rohrbach

Patent number: 9296548Abstract: A dispenser for utility-knife blades has a longitudinally elongated housing having a longitudinally forwardly open front end and a pair of transversely confronting inner faces each formed with a flat front portion terminating at the open front end and a flat rear portion. Each front portion is offset transversely outward from the respective rear portion and forms therewith a respective longitudinally forwardly directed shoulder. A slide in the housing is formed with a transversely throughgoing compartment adapted to hold a stack of the utility knife blades. The slide is shiftable between a rear position with the stack of blades resting by gravity on the rear portion of whichever inner face is directed upward and a front position with the stack resting on the front portion of the upwardly directed inner face and forward of the shoulder of the upwardly directed inner face. The offset is equal generally to a thickness of a single blade.Type: GrantFiled: September 29, 2010Date of Patent: March 29, 2016Assignee: MARTOR KGInventor: Peter Schekalla
