Abstract
A drill is provided with a chuck that is capable of being tightened or loosened by operation of the drill. The chuck includes a shift mechanism that interacts with the multi-speed transmission of the drill to ensure that the transmission is shifted into a desired gear ratio whenever the chuck is shifted from a drill mode to a chuck mode.
Claims27
A drill, comprising:
- a motor;
- a multi-speed transmission device drivingly connected to said motor, said multi-speed transmission device being operable in at least two gear ratios;
- a chuck drivingly connected to said multi-speed transmission device, said chuck being operable in a drilling mode and a chuck loosening mode, said chuck including an actuating device that is operable to switch said chuck from said drilling mode to said chuck loosening mode and simultaneously switching said multi-speed transmission device to a desired gear ratio.
A drill, comprising:
- a motor;
- a multi-speed transmission device drivingly connected to said motor, said multi speed transmission device being operable in at least two gear ratios;
- a chuck drivingly connected to said multi-speed transmission device, said chuck being operable in a drilling mode and a chuck tightening mode, said chuck including an actuating device that is operable to switch said chuck from said drilling mode to said chuck tightening mode and simultaneously switching said multi-speed transmission device to a desired gear ratio.
A drill, comprising:
- a motor;
- a multi-speed transmission device drivingly connected to said motor, said multi speed transmission device being operable in at least two gear ratios;
- a chuck drivingly connected to said multi-speed transmission device, said chuck being operable in a drilling mode and a chuck mode, said chuck including an actuating device that is operable to switch said chuck from said drilling mode to said chuck mode;
- and
- a lock out device engaged with said chuck and a shift mechanism of said multi-speed transmission device and adapted to prevent said chuck from being switched to said chuck mode unless said multi-speed transmission is in a predetermined one of said at least two gear ratios.

A drill, comprising:
- a motor;
- a multi-speed transmission device drivingly connected to said motor, said multi speed transmission device being operable in at least two gear ratios;
- a chuck drivingly connected to said multi-speed transmission device, said chuck being operable in a drilling mode and a chuck mode, said chuck including an actuating device that is operable to switch said chuck from said drilling mode to said chuck mode;
- and
- a lock out device engaged with said chuck and a shift mechanism of said multi-speed transmission device and adapted to prevent said multi-speed transmission from being switched from a predetermined one of said at least two gear ratios while said chuck is in said chuck mode.
