A staircase carpet stretcher, including a frame assembly, a manipulation assembly springingly connected to at least a portion of the frame assembly to facilitate gripping thereof, a first stretch bar assembly removably connected at a first end of the frame assembly to connect to a carpet of a staircase and move in response to compression of the manipulation assembly, and a second stretch bar assembly removably connected at a second end of the frame assembly to connect to the carpet and prevent movement of the frame assembly on the carpet.

A carpet air kicker comprises a body, a rod, a spring and a controlling switch. The body defines an interior chamber including a front chamber and a rear chamber. A front end and a rear end of the rod have a gripping head and a piston respectively. The piston is located in the interior chamber such that the front chamber is not communicated with the rear chamber. A piston assembly of the body is connected to the rod and located between a front end of the body and the front chamber. The spring is installed in the rear chamber. A communicating hole is communicated with the front chamber. The controlling switch controls the front chamber communicated with external air such that the spring pushes the rod moving forward or communicated with an air compressor such that an air pressure pushes the rod moving backward.

A carpet installation tool assembly configured to stretch carpet between two non-parallel walls is provided. The carpet installation tool assembly comprises a first leg positioning assembly, a second leg positioning assembly, a central frame member, and a hinge arm tool. The carpet installation tool assembly can be used to stretch carpet to minimize waves and bunching during installation of carpet in rooms that are not square.

A carpet stretcher comprising: a head mechanism; a tail mechanism; and an elongate extender; wherein the head mechanism is connected to a distal end of the elongate extender, and the tail mechanism is connected to a proximal end of the elongate extender; and wherein: the head mechanism comprises: a head element having a carpet engaging surface; an extension element for extending the elongate extender at its distal end so as to urge the head element distally; and a lever mechanism for actuating the extension element; characterised in that the tail mechanism comprises a tail element having a carpet engaging surface.
