Abstract
An apparatus for indicating a drilling thrust of a hand-operated drill includes a thrust-indicator assembly for attaching between a drill motor and a drill chuck of the hand-operated drill to indicate the drilling thrust. A method of indicating a drilling thrust asserted on a hand-operated drill includes: attaching a thrust-indicator assembly between a drill motor and a drill chuck of a hand-operated drill; and indicating, with the thrust-indicator assembly, a drilling thrust asserted on the drill chuck.
Claims25
An apparatus which indicates a drilling thrust of a hand-operated drill comprising:
- a thrust-indicator assembly configured to attach between a drill motor and a drill chuck of a hand-operated drill to indicate a drilling thrust, the thrust-indicator assembly comprising:
- a driven member, a driver member, a driven mating member, and a driver mating member;
- wherein when the drill motor is rotating and a drilling thrust is under a thrust threshold the driver mating member is configured to extend through a hole in the driver member and through a slot in the driven member and the driven mating member is configured to remain mated with the driver mating member so that the driven member rotates with the driver member so that the driven member rotates the drill chuck;
- wherein when the drill motor is rotating and the drilling thrust is over the thrust threshold the driven mating member is configured to un-mate from the driver mating member so that the driven member stops rotating thereby stopping rotation of the drill chuck while the driver member continues to rotate with the drill motor.
A hand-operated drill comprising:
- a drill motor;
- a drill chuck;
- and
- a thrust-indicator assembly attached between the drill motor and the drill chuck to indicate a drilling thrust, the thrust-indicator assembly comprising:
- a driven member, a driver member, a driven mating member, and a driver mating member;
- wherein when the drill motor is rotating and a drilling thrust is under a thrust threshold the driver mating member is configured to extend through a hole in the driver member and through a slot in the driven member and the driven mating member is configured to remain mated with the driver mating member so that the driven member rotates with the driver member so that the driven member rotates the drill chuck;
- wherein when the drill motor is rotating and the drilling thrust is over the thrust threshold the driven mating member is configured to un-mate from the driver mating member so that the driven member stops rotating thereby stopping rotation of the drill chuck while the driver member continues to rotate with the drill motor.
A method of indicating a drilling thrust asserted on a hand-operated drill comprising:
- attaching a thrust-indicator assembly, comprising a driven member, a driver member, a driven mating member, and a driver mating member, between a drill motor and a drill chuck of a hand-operated drill;
- and
- indicating with the thrust-indicator assembly a drilling thrust asserted on the drill chuck so that when the drill motor is rotating and the drilling thrust asserted on the drill chuck is below a thrust threshold the thrust-indicator assembly rotates the drill chuck due to the driver mating member extending through a hole in the driver member and through a slot in the driven member thereby mating the driven member to the driver member so that the driven member rotates with the driver member thereby rotating the drill chuck, but when the drilling thrust asserted on the drill chuck exceeds the thrust threshold the thrust-indicator assembly stops rotating the drill chuck due to the driven mating member un-mating from the driver mating member thereby un-mating the driven member from the driver member so that the driven member stops rotating thereby stopping rotation of the drill chuck while the drill motor continues to rotate.
