Abstract
A mobile saw stand brake system incorporates a pair of swing-out legs pivotally connected to a saw stand main frame. A first end of the main frame is supported on a pair of rotating wheels. A pair of brake lever arms, each having a brake shoe end and a distal actuating end, are pivotally connected to the main frame. A tension mechanism is interconnected with the pair of swing-out legs so as to actuate the brake lever arms to engage the wheels when the legs are extended in their swing-out position. The brakes are disengaged when the swing-out legs are folded into a stowed position.
Claims20
A mobile saw stand brake system, comprising:
- a substantially handtruck-shaped main frame having a pair of elongated, laterally coextensive spaced-apart frame rails terminating at a first end in a transversely directed foot portion;
- a pair of wheels each having an external periphery and being rotatably connected to the main frame adjacent to the first end;
- a pair of swing-out legs pivotally connected to the main frame at a distal end from the first end so as to be movable between a stowed, closed position and an extended support position;
- a pair of brake lever arms each having a brake shoe end and a distal actuating end defining a midsection therebetween, the midsection of each lever arm being pivotally connected to the main frame such that the brake shoe ends are proximal to the wheel peripheries for engagement therewith;
- and,
- tension means connected to the main frame and the swing-out legs for actuating the brake lever arms when the legs are moved to the extended support position whereby the wheels are substantially prevented from rolling.

- a pair of wheels each having an external periphery and being rotatably connected to the main frame adjacent to the first end;
- a swing-out leg frame pivotally connected to the main frame at an end distal from the first end so as to be movable between a stowed, closed position and an extended support position;
- and,
- a brake lever arm having a brake shoe end and a distal actuating end defining a midsection therebetween, the midsection being pivotally connected to the main frame such that the brake shoe end is proximal to one of the wheel peripheries for engagement therewith;
- and,
- force transferring means connected to the main frame and the swing-out leg frame for actuating the brake lever arm when the leg frame is moved to the extended support position whereby one of the wheels is substantially prevented from rolling.
