Abstract
A clamp includes a jaw assembly, and an actuator device for moving the jaw assembly between clamped and unclamped positions. The actuator device includes a handle, and a keyed shaft coupled to the handle via a spring biased releasable torque transfer mechanism.
Claims20
A clamp comprising:
- a jaw assembly, and
- an actuator device for moving the jaw assembly between clamped and unclamped positions, including:
- a rotatable handle member,
- a driver shaft connected to the handle member for engaging the jaw assembly, and
- a first set of teeth rotationally fixed relative to the handle member, and a second set of teeth rotationally fixed relative to the driver shaft, the first set of teeth engaging the second set of teeth until a threshold level of torque is applied by the handle member to the driver shaft, after which the first set of teeth slide over the second set of teeth, wherein the teeth in at least one of the first and second sets of teeth are spring biased into engagement with the other set of teeth.
2 more elements
A clamping assembly for securing a cargo box on to a pair of crossbars on top of a vehicle, comprising:
- four clamps fastened to a floor of a cargo box, each clamp having a jaw assembly and being adjustable by one single actuator device for moving each respective jaw assembly serially between clamped and unclamped positions, the single actuator device including:
- a rotatable handle member,
- a driver shaft connected to the handle member for engaging the jaw assembly, and
- a first set of teeth rotationally fixed relative to the handle member, and a second set of teeth rotationally fixed relative to the driver shaft, the first set of teeth engaging the second set of teeth until a threshold level of torque is applied by the handle member to the driver shaft, after which the first set of teeth slide over the second set of teeth, wherein the teeth in at least one of the first and second sets of teeth are spring biased into engagement with the other set of teeth.
1 more element
A tool for driving rotation of a threaded member, comprising:
- a handle, and
- a keyed shaft coupled to the handle via a spring biased releasable torque transfer mechanism.
