摘要:
Safety systems for power equipment, components, cartridges and mounting systems for cartridges are disclosed. The safety systems, components, cartridges and mounting systems are specifically applicable for woodworking equipment such as saws. A cartridge system for use in safety systems for power tools might include a cartridge adapted to perform a predetermined action when triggered, where the predetermined action causes the deceleration and/or retraction of a working portion of the power tool, where the cartridge includes a first connector, and where a second connector is mounted in the power tool and adapted to connect to the first connector.

Table saws and table saws designed to implement safety systems that detect contact between a person and a dangerous portion of the saw are disclosed. Table saw components, mounting systems for table saws, and table saw attachments are also disclosed. One embodiment may include a first clamp surface, a second clamp surface spaced apart from the first clamp surface so that a base portion of a riving knife or splitter can be placed between the clamp surfaces with the opposing sides of the base portion generally parallel to the first and second clamp surfaces.

Improved table saws and table saws designed to implement safety systems that detect contact between a person and a dangerous portion of the saw are disclosed. The table saws may include an elevation mechanism, a tilt mechanism, and an adjustment system configured to adjust the parallelism between a tilt axis and a blade. The elevation mechanism may include a vertical slide that includes two shafts, and the adjustment system may include a mechanism to adjust the parallelism of the two shafts.
摘要:
A woodworking machine is disclosed. The machine includes a cutting tool and a motor adapted to drive the cutting tool. The machine further includes a detection system to detect a dangerous condition between the cutting tool and a person, such as a person coming into contact with the cutting tool. A reaction system is provided to disable the cutting tool, such as by covering, blocking, destroying, wrapping, etc., upon detection by the detection system of the dangerous condition.

Throat plates for table saws and table saws including the same are disclosed. In some embodiments, the throat plates and/or saws include at least one securement mechanism adapted to secure and prevent inadvertent removal of the throat plate from the throat of the saw. In some embodiments, at least one of the securement mechanisms also provides a height adjustment mechanism and/or prevents vertical removal of the throat plate. In some embodiments, the throat plate includes an accessory mounting port that provides a portal for accessories, including safety accessories, to extend through the plate from beneath the table of the saw. In some embodiments, the port extends from the plate's outer perimeter to divide the plate's rear end portion into a pair of spaced-apart members. In some embodiments, these members are independently secured to the table saw and retained apart from each other by one or more of the securement mechanisms.
摘要:
Table saws are disclosed. The table saws may include a circular blade, an elevation mechanism configured to raise and lower the blade relative to the work surface; and a spring to provide a force biasing the blade up or down relative to the work surface. The spring may be a gas spring connected between a trunnion and an elevation plate.

Safety systems for power equipment and components and brake cartridges for use in those safety systems are disclosed. The safety systems, components and brake cartridges are specifically applicable for woodworking equipment such as saws. An exemplary brake cartridge includes a housing and a braking component configured to engage a moving part of the power tool upon occurrence of a predetermined event. The brake cartridge may further include a switch configured so that proper installation of the cartridge in the power tool triggers the switch.
