    • A knife has a housing, an operating part shiftable on the housing between advanced and retracted positions, and a blade holder connected to the part and carrying a blade. The holder is shiftable on the part between offset first and second cutting positions with the blade projecting from the front end and a safety position with the blade recessed in the housing rearward of the front end. A spring biases the holder into the safety position. A brace element can shift between a position braced between the blade holder and the housing in the first cutting position and a position out of engagement with the blade holder or the housing in the second cutting position. The brace element when engaged holds the blade in the first cutting position but in the second cutting position is disengaged so the spring returns the holder to the safety position.
    • 刀具有壳体,可在前进位置和缩回位置之间在壳体上移动的操作部件和连接到该部件并承载刀片的刀片保持器。 保持器可以在偏移的第一和第二切割位置之间的部分上移动,其中刀片从前端突出,并且刀片在前端向后凹入壳体中的安全位置。 弹簧将支架偏压到安全位置。 支撑元件可以在第一切割位置之间的支撑在刀片保持器和壳体之间的位置之间移动,并且在第二切割位置中与刀片保持器或壳体接合的位置。 支撑元件在接合时将刀片保持在第一切割位置但是在第二切割位置处脱离,使得弹簧将保持器返回到安全位置。

    • The invention relates to a knife, comprising a blade carrier (14) for holding a blade (15), having at least one primary knife part (11) and a secondary knife part (12), which is configured to be movable relative to the primary knife part (11), wherein the primary knife part (11) is associated with first coupling means (20, 36), which can be detachably engaged with second coupling means (18, 38) associated with the secondary knife part (12) in order to move the blade carrier (14) by way of a motion of the primary knife part (11) relative to the second knife part (12) between a safety position, in which the blade (15) is retracted into a knife housing (11) configured by the primary knife part (11) and/or the secondary knife part (12) and inaccessible to the user, and an intermediate position, in which the blade (15) protrudes from the knife housing (11), wherein the blade carrier (14) is subjected to a load by a restoring force (21) in the safety position. The special characteristic is that the blade carrier (14) is pivotally mounted about a fixedly disposed rotational axis (a2), that by the action of a cutting force (F) on the blade (15) the blade carrier (14) can be moved out of the intermediate position into a cutting position, and that in the cutting position the first coupling means (20, 36) and the second coupling means (18, 38) are detached from each other such that the blade carrier (14) can be moved into the safety position.

    • A knife has a blade holder in a housing adapted to hold a blade and shiftable between a first cutting position with the blade projecting a little from the housing and a second position projecting somewhat more from the housing. An actuating element shiftable in the housing between a starting position and an actuating position is effective on a connecting linkage such that in a first orientation force is transmitted to the blade holder to retain the blade holder against moving into its retracted safety position from its first cutting position and in the second orientation the linkage does not prevent the blade holder from moving into its safety position from its second cutting position.
    • 刀具具有在壳体中的刀片保持器,其适于保持刀片并且可在具有从壳体突出一点的刀片的第一切割位置和从壳体稍微更多地突出的第二位置之间移位。 在壳体中在起始位置和致动位置之间移动的致动元件在连接联动装置上是有效的,使得在第一取向力被传递到刀片保持器以保持刀片保持器抵抗其从其第一切割中移动到其缩回的安全位置 位置,并且在第二方向上,连杆不阻止刀片保持器从其第二切割位置移动到其安全位置。

    • A knife has a housing, a blade carrier supported in the housing and adapted to hold a blade, and an actuating element coupled to the blade carrier. A handle can move between a nonactuated position and an actuated position and is coupled to the actuating element such that on movement from the nonactuated position to the actuated position the actuating element displaces the blade carrier from a safety position in which blade mounted on the blade carrier is retracted into a seat of the housing in a first cutting position in which the blade projects out of the housing. A pivot joint connects the actuating element with the blade carrier. A guide supports the blade carrier in a translatory and a rotatable manner on the housing.
    • 刀具有壳体,支撑在壳体中并适于保持叶片的叶片载体以及联接到叶片载体的致动元件。 手柄可以在非致动位置和致动位置之间移动并且联接到致动元件,使得在从非致动位置移动到致动位置时,致动元件将刀片承载件从安装在刀片承载器上的刀片的安全位置移位 在第一切割位置缩回到壳体的座中,在第一切割位置,刀片突出到壳体外。 枢转接头将致动元件与叶片承载件相连接。 引导件以平移和可旋转的方式支撑刀片托架在壳体上。

The holder is shiftable on the part between offset first and second cutting positions with the blade projecting from the front end and a safety position with the blade recessed in the housing rearward of the front end. A spring biases the holder into the safety position.

The brace element when engaged holds the blade in the first cutting position but in the second cutting position is disengaged so the spring returns the holder to the safety position.
