摘要:
A saw with a safety system is disclosed. The safety system includes a detection system adapted to detect contact between a person and a blade while the blade is moving. The safety system further includes a brake system adapted to engage the blade and to stop the blade when the detection system detects contact between the person and the blade.
摘要:
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. Table saw components, mounting systems for table saws, and table saw attachments are also disclosed.
摘要:
Switch boxes for power tools with safety systems are disclosed. The switch boxes are particularly useful for woodworking equipment such as table saws equipped with safety systems that detect and react to dangerous conditions. The switch boxes may include a power switch, a start/stop switch and a bypass switch.
摘要:
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.
摘要:
Improved fences for table saws. In some embodiments, the fence includes removable face plates. In some embodiments, the fence includes an improved clamping mechanism. In some embodiments, the fence includes improved glide structure. In some embodiments, the fence includes a biasing mechanism adapted to urge the fence against the table of the saw. In some embodiments, the fence includes improved adjustment structure for aligning the fence relative to the table.
摘要:
A woodworking machine including a detection system adapted to detect a dangerous condition between a person and a working portion of the machine is disclosed. The machine includes a reaction system associated with the detection system to cause a predetermined action to take place relative to the working portion upon detection of the dangerous condition. A motion detection system is adapted to detect motion of the working portion and to disable the reaction system when the working portion is not moving. The motion detection system may include a sensor, such as a Hall effect sensor, an electromagnetic field sensor, an optical sensor, or an electrical sensor. The woodworking machine may take the form of a saw, the working portion may be a blade adapted to cut when spinning, and the dangerous condition may be a person contacting the blade.
摘要:
A machine is disclosed having a detection subsystem adapted to detect contact between a person and a specified portion of the machine, and to distinguish that contact from contact with other materials. The detection subsystem imparts an electrical signal to a specified portion of the machine, and distinguishes that contact based on a predetermined frequency response of the electrical signal. A reaction subsystem then causes a predetermined action to take place. The machine may be a power saw designed to minimize injury in the event a person accidentally contacts the blade.
摘要:
Brake pawls for use in safety systems for power equipment are disclosed. The brake pawls include an energy-absorbing region. The energy absorbing regions may include a deformable or collapsible region made from apertures in the brake pawl or from collapsible members or from materials of differing hardnesses, strengths, or structures.
摘要:
A table saw having a brake mechanism configured to engage and stop a blade is disclosed. The table saw includes a brake positioning system configured to adjust the position of the brake mechanism to maintain the brake mechanism in an operative position relative to the blade as the blade is raised and lowered.
摘要:
Miter saws are disclosed having a base, a blade supported by the base, a detection system adapted to detect a dangerous condition between a person and the blade, and a reaction system associated with the detection system to cause a predetermined action to take place upon detection of the dangerous condition. The blade is rotatable, and moves into a cutting zone to cut a workpiece. The predetermined action may be to stop the blade from rotating, to create an impulse against movement of the blade into the cutting zone, or to cause the blade to move away from the cutting zone.
