摘要： A folding hand tool with an open-assist mechanism that is not mechanically linked to a folding knife blade is disclosed. The open-assist mechanism is allowed to rotate around the same pivot used by the blade, and includes a lug that interacts with the kick of the blade when rotated. Because the open-assist mechanism is not mechanically linked to the blade, it has a range of free motion that promotes safety, and allows the mechanism to rotate into the blade cavity when the blade is extended. The folding knife also may have a carabiner that shares the blade cavity with the blade, with the blade nesting into the carabiner to save space, thereby giving the folding knife a smaller profile.
摘要翻译： 公开了一种具有不与折叠刀片机械连接的打开辅助机构的折叠式手动工具。 允许打开辅助机构围绕由刀片使用的相同枢轴旋转，并且包括当旋转时与刀片的踢脚相互作用的凸耳。 由于开启辅助机构并不机械地连接到叶片上，所以它具有一定范围的自由运动，这促进了安全性，并且当刀片延伸时允许机构旋转到叶片腔中。 折叠刀还可以具有与刀片共享刀片腔的锁扣，刀片嵌入锁扣以节省空间，从而给折叠刀更小的轮廓。

摘要： A multipurpose tool includes bypass shears with handles that fold around the shears into a compact configuration in which the blades of the shears are hidden. A sharp-edged cutter is removable from the shears for resharpening or replacement, in one version of the tool. A blade safety lock holds the blades closed and is automatically engaged as the handles are folded. The handles are comfortably shaped and may include overmolded elastomeric cushioning portions.

摘要： Inserts for table saws are disclosed. The table inserts are equipped with a toolless locking mechanism that mechanically holds the insert in place and which allows for the installation and removal of the insert without the use of tools. The locking mechanism is easy to lock and unlock and yet robust enough to hold a zero-clearance insert in place.

摘要： A locking sheath and knife combination is provided that includes a spring biased member that partially extends out of the handle of the knife and interacts with a catch on the sheath for securing the knife to the sheath. When the user wants to extract the knife from the sheath, the spring biased member is squeezed as the handle is grabbed, which rotates the spring biased member to be substantially fully contained within the handle of the knife, and is secured there by the lock spring plate. When the knife is inserted back into the sheath, a protrusion on the sheath interacts with the lock spring plate to automatically allow the spring biased member to rotate out of the handle, thereby securing the knife to the sheath.

摘要： A dust collection system designed for a table saw is disclosed. The dust collection system includes a dust shroud and dust shield to channel dust generated by a blade as it cuts wood or other material. The dust shroud includes fins and walls to “peel” dust and air off a spinning blade and direct the dust and air downward. The dust shroud encloses the lower front portion of a blade. An insert with a channel into which a dust shield can extend is disclosed.

摘要： A folding tool and an associated locking mechanism are provided in order to securely and reliably retain an implement, such as a knife blade, in an open position. The folding tool may include a handle, an implement pivotally connected to the handle and a lock. The lock, in turn, may include an engagement member for movement with the blade and a pivotable member, such as a cam member, configured to pivot relative to the handle between first and second positions. As a result of controlled interaction between the engagement member and the pivotable member, such as a result of camming action provided by the cam member, the rotatable implement can be secured in the open position. If desired, the rotatable implement may be released and folded into the closed position.

摘要： Blade guards for power tools such as table saws are disclosed. The blade guard may include a shroud that pivots up and down to allow a workpiece to move past the guard, a dust collection channel, and a pivot joint which maintains the dust collection channel in an operable condition as the shroud pivots up or down. The guard may also include a wood stop and anti-kickback pawls. The blade guard may be part of a dust collection system and may be connected to a vacuum system by a conduit such as a flexible hose.

摘要： A tool and an associated bit driver are provided. The tool includes a handle and a bit driver carried by the handle. The bit driver can include a body defining a cavity for receiving a bit and a pivotable lock configured to move between a locked position in which the lock engages the bit and an unlocked position in which the lock is spaced and thereby disengaged from the bit. The pivotable lock can include a pivot pin, an engagement member for engaging the bit and an actuation member with the engagement and actuation members extending along the body in opposite directions from the pivot pin.

摘要： Fast-acting and low-inertia actuators useable in various applications where a high force must be applied very quickly are disclosed. Power tools with detection systems configured to detect a dangerous condition between a person and a cutting tool are disclosed. In power tools, for example in a woodworking machine, a fast-acting and low-inertial actuator as disclosed herein can be used to retract a blade upon detection of a dangerous condition by a detection system. The actuator includes a charge of pressurized fluid and one or more electromagnets to selectively retain or release the pressurized fluid.
