Abstract
A carpet laying device comprises an anchor unit, a mobile unit and a drive system. The mobile unit and the anchor unit are secured to the carpet by suction provided by electrically driven exhaust fans. In use, the mobile unit is driven by the drive system away from the anchor unit to smooth out or stretch the carpet, the friction between the carpet and the mobile unit being weaker than that between the carpet and the anchor unit. In an alternative device, the anchor unit is a cushioned pad for abutment with a wall.
Claims20
A carpet laying device comprising:
- track forming means having a first end and a second, opposite, end, for extending across a carpet covering a floor so that the first end and second, opposite, end are adjacent first and second, opposite, edges of the carpet, respectively;
- securing means on the first end of the track forming means for securing the first end relative to the first edge of the carpet;
- suction producing, engaging means for slidingly engaging the carpet by suction;
- and,
- means for advancing the engaging means along the track forming means over the carpet in continuous sliding engagement therewith from a position adjacent the first end away from the securing means to a position adjacent the second end while applying a suction force to the carpet continuously throughout such advance so that an increasing length of carpet between the engaging means and the securing means is progressively drawn taut and flat and maintained in taut and flat condition by suction produced by the engaging means.

- securing means on the first end of the track forming means for securing the first end relative to the first edge of the carpet;
- suction producing, engaging means for slidably engaging the carpet by suction and comprising a hollow housing having a lower, carpet engaging end provided with a carpet engaging, suction inlet aperture spanned by a perforated, carpet engaging barrier, and a suction fan mounted in the housing at a location remote from the carpet engaging end;
- and,
- drive means operably connected to the engaging means and engaged with the track means for advancing the carpet engaging means along the track over the carpet in continuous sliding engagement therewith from a position adjacent the first end away from the securing means to a position adjacent the second end while applying a suction force to the carpet continuously throughout such advance so that an increasing length of carpet between the engaging means and the securing means is progressively drawn taut and flat and maintained in taut and flat condition by suction produced by the engaging means.

A method of laying a carpet in a room including the steps of:
- a) securing one edge of the carpet to a floor of the room adjacent one wall of the room with a remainder of the carpet extending in slack condition across the floor toward another wall of the room, opposite the one wall;
- b) applying suction to a portion of an upper surface of a remainder of the carpet at a position adjacent the one edge, and progressively advancing a point of application of the suction across the surface away from the position adjacent the one edge to another position adjacent another edge of the carpet, opposite the one edge and adjacent said another wall while continuously applying the suction throughout such advance, thereby drawing and maintaining a portion of the carpet between the one edge and the suction into a taut, flat condition;
- c) securing a part of the opposite edge of the carpet adjacent said another position to the floor adjacent the opposite wall;
- and,
- repeating steps b) and c) for different portions of the remainder of the carpet until an entire opposite edge of the carpet has been secured to the floor with the remainder of the carpet lying flat, thereon in taut condition.
