Taping tool having improved creaser wheel operation

An apparatus for dispensing and creasing tape for application to a joint between wallboard members, said apparatus comprising:

• a device for dispensing tape over a joint between wallboard members, said device having a first end and a second end distant from said first end, said device being adapted to dispense tape from a location near said second end;
• a wheel pivotally mounted to said device near said second end for causing a crease in tape dispensed from said device, said wheel being configured to pivot relative to said device into a plurality of positions between a first position of said plurality of positions farthest from said first end of said device and a second position of said plurality of positions nearest said first end of said device;
• and
• a first actuator connected to said device for receiving user input corresponding to a position of said wheel desired by a user;
• wherein in the absence of user input via said first actuator, said wheel resides substantially in said first position;
• wherein said device is further configured for dispensing mastic and further comprises a second actuator for receiving user input controlling a flow of mastic;
• and
• wherein said first actuator and said second actuator are adapted for simultaneously receiving user input from a single hand of a user.

An apparatus for dispensing and creasing tape for application to a joint between wallboard members, said apparatus comprising:

• an elongate first device for dispensing tape over a joint between wallboard members, said first device having a first end and a second end distant from said first end, said first device being adapted to dispense tape from a location near said second end;
• a second device mounted to said first device near said second end thereof for causing a crease in tape dispensed from said first device, said second device being configured to pivot relative to said first device into a plurality of positions between a fully-extended first position of said plurality of positions farthest from said first end of said first device and a fully-retracted second position of said plurality of positions nearest said first end of said first device;
• and
• an actuator connected to said first device for receiving user input corresponding to a position of said second device desired by a user;
• wherein in the absence of user input received by said actuator, said second device resides in said fully-extended first position;
• wherein said actuator is connected to said first device near said first end thereof and is adapted to control positioning of said second device relative to said first device in response to user input, wherein said first end of said first device is rotatable relative to said second end of said first device about a longitudinal axis of said first device, and wherein positioning of said second device is controllable by said actuator regardless of the angular orientation about said longitudinal axis of said first end of said first device relative to said second end of said first device.

An apparatus for dispensing and creasing tape for application to a joint between wallboard members, said apparatus comprising:

• an elongate first device for dispensing tape over a joint between wallboard members and having a first portion and a second portion, said first device being adapted to dispense tape from said second portion;
• a second device pivotally mounted to said second portion of said first device for causing a crease in tape dispensed from said first device, said second device being configured to pivot relative to said second portion of said first device into a plurality of positions between a fully-extended first position of said plurality of positions and a fully-retracted second position of said plurality of positions;
• and
• an actuator connected to said first portion of said first device for receiving user input corresponding to a position of said second device desired by a user;
• wherein in the absence of user input received by said actuator, said second device resides substantially in said fully-extended first position;
• wherein said second portion of said first device is rotatably connected to said first portion of said first device for relative rotation therebetween about a longitudinal axis, wherein said apparatus further comprises a member rotatable about said longitudinal axis in unison with said second portion of said first device for transmitting a force to said second device corresponding to movement of said actuator in response to user input, wherein said apparatus further comprises a mechanism connected to said actuator and rotatable about said longitudinal axis in unison with said first portion of said first device, and wherein said mechanism and said member are configured for relative rotation therebetween and said mechanism is configured to cause translation of said member in response to movement of said actuator.
