Abstract
A carpet installation tool comprises a portable body which is forwardly equipped with a spring tensioned anchoring blade to engage behind a tackless carpet strip. The body downwardly carries a carpet gripper head which includes a plurality of pins suitable for engaging the carpet and stretching the carpet upon use of the tool. A motor is carried within the frame to function either a gear train or a hydraulic cylinder to move the carpet gripper head relative to the anchoring blade under motor power for carpet stretching purposes. The tool also includes a wall contacting pole and a socket to receive one end of the pole whereby the carpet gripper head can be moved by motor power relative to the pole for carpet stretching purposes.
Claims17
In a carpet installation tool of the type including a carpet gripper head, the combination of
- a frame;
- means to move the carpet gripper head relatively to the frame for carpet stretching purposes, said means to move being power actuated,
- said means to move comprising elongated means responsive to the power actuation to move the the gripper head forwardly or rearwardly relative to the frame,
- said means to move comprising hydraulic circuit means to urge the carpet gripper head forwardly or rearwardly by using hydraulic pressure,
- the hydraulic circuit means comprising a pump supplying hydraulic pressure to a cylinder and a piston movable within the cylinder in response to hydraulic pressure,
- the piston being connected to a piston rod, the said piston rod extending outwardly of the cylinder and being affixed to move the carpet gripper head,
- said means to move further including means to prevent rotation of the gripper head relative to the frame
- said means to prevent rotation comprising at least a portion of the piston rod being non-circular in cross sectional configuration.
In a carpet installation tool of the type including a carpet gripper head, the combination of
- a frame,
- the frame comprising a housing;
- means to move the carpet gripper head relatively to the frame for carpet stretching purposes, said means to move being power actuated,
- said means to move comprising elongating means responsive to the power actuation to move the gripper head forwardly or rearwardly relative to the frame,
- said means to move comprising an electric motor and a ram extending from the carpet gripper head,
- said ram having sliding movement relative to the frame,
- said ram being provided with a threaded section,
- said means to move comprising a gear train interposed between the motor and the threaded section to move the carpet gripper head relative to the frame upon function of the motor;
- the said ram being a sliding fit within the housing;
- said means to move further comprising means to prevent rotation of the gripper head relative to the frame;
- said means to prevent rotation comprising at least a portion of the ram being non-circular in cross sectional configuration.
