摘要： A utility knife has a blade carrier defining a blade support surface movably mounted in a housing between retracted and extended positions. A catch is mounted on the blade carrier and is movable between a first position engagable with a blade seated on the blade carrier and substantially preventing the blade from moving relative to the blade carrier, and a second position spaced away from the blade located on the blade carrier and permitting removal of the blade from the blade carrier. An actuator is mounted on the blade carrier and is operable to move the blade carrier between the retracted and extended positions to, in turn, move a blade located on the blade carrier between retracted and extended positions, and move the catch between the first and second positions to release a blade from the blade carrier. The housing has a nose portion that defines the blade aperture and is made of a more wear-resistant material than the other portions of the housing. A sheet material spare blade holder is mounted within the housing and defines a fold, a support portion located on one side of the fold, and a biased retaining portion located on the other side of the fold for receiving spare blades therebetween.

摘要： A handle for a utility knife includes a housing made up of two or more portions. In one embodiment, a manually operable member for use in releasing the blade is retained to at least one portion of the housing and does not become separated from the housing when the housing is in an open state. In another embodiment, a catch for engaging the blade extends from a support member that is slidably movable within the housing. In another embodiment, the housing is formed of metal and a nose portion is formed of a metal that is more wear resistant than the rest of the housing, in order to improve the durability of the nose portion. In another embodiment, a bail screw is captured on a first housing portion and threadedly engageable with a second housing portion for (i) releasably securing the first and second housing portions in a fully closed state and, in turn, releasably securing a blade within the blade opening, and (ii) manually positioning at least one of the first and second housing portions in at least one intermediate state between the fully closed state and a fully opened state to, in turn, permit the blade to be manually moved through the blade opening.
摘要翻译：用于实用刀的手柄包括由两个或多个部分构成的壳体。在一个实施例中，用于释放刀片的可手动操作的构件被保持在壳体的至少一个部分上，并且在壳体处于打开状态时不会与壳体分离。在另一个实施例中，用于接合刀片的卡扣从可在壳体内可滑动地移动的支撑构件延伸。在另一个实施例中，壳体由金属形成，并且鼻部由比外壳的其余部分更耐磨的金属形成，以便提高鼻部的耐久性。在另一个实施例中，吊环螺钉被捕获在第一壳体部分上并与第二壳体部分螺纹接合，用于（i）可释放地将第一和第二壳体部分固定在完全关闭状态，并且可释放地将叶片固定在刀片开口，和（ii）在完全关闭状态和完全打开状态之间手动将至少一个第一和第二壳体部分定位在至少一个中间状态，从而允许刀片被手动地移动通过刀片开放

摘要： A folding utility knife has a handle and a blade holder pivotally mounted on he handle. The blade holder is movable between (i) a closed position with the blade holder pivoted inwardly toward the handle, (ii) a cutting position with the blade holder pivoted outwardly relative to the handle, and (iii) a blade release position located between the closed position and the cutting position. A blade release actuator is located on the blade holder and is movable between (i) a first position preventing release of a utility knife blade located on the blade holder, and (ii) a second position permitting release of a utility knife blade located on the blade holder. A locking member is movable between (i) a blade locking position with the blade holder located in the cutting position that prevents movement of the blade release actuator from the first position to the second position, and (ii) a blade release position with the blade holder located in the blade release position that permits movement of the blade release actuator from the first position to the second position to, in turn, release a utility knife blade from the blade holder.
摘要翻译：折叠式实用刀具具有手柄和可旋转地安装在手柄上的刀架。刀片保持器可在（i）关闭位置与刀片保持器之间移动，刀片保持器向内朝向手柄转动，（ii）刀片保持器相对于把手向外转动的切割位置，以及（iii）刀片释放位置关闭位置和切割位置。刀片释放致动器位于刀片保持器上并且可以在（i）防止位于刀片保持器上的实用刀片的释放的第一位置和（ii）允许释放位于刀片保持器上的实用刀片的第二位置之间移动刀架。锁定构件可在（i）刀片锁定位置与刀片保持器之间移动，刀片保持器位于切割位置，防止刀片释放致动器从第一位置移动到第二位置，以及（ii）刀片释放位置与刀片位于刀片释放位置的保持器，其允许刀片释放致动器从第一位置移动到第二位置，从而将刀片刀片从刀片保持器释放。

摘要： A utility knife includes a body having a groove adapted to receive a blade. The groove has a plurality of tabs defined on at least a first side. The utility knife also includes a slide assembly device positioned in the body for sliding movement with respect to the body. The slide assembly device includes a housing with a first engaging member having a first protrusion and a second engaging member having a second protrusion releasably engaged with the tabs. The slide assembly device also includes a rocker attached to the housing that is operatively connected to at least one of the engaging members. The rocker is operable for disengaging the first protrusion or second protrusion with respect to the tabs. Disengaging one of the first and second protrusions by the rocker allows sliding movement of the slide assembly device with respect to the body.
