  • Patent number: 5288057
    Abstract: A carpet stretching device using a power stretching adapter attached to a standard carpet kicker is provided. The stretching adapter is formed from a frame having an anchor plate attached to the front of the frame for anchoring the device between the wall and tack strip adjacent to the carpet edge to be stretched. A handle is provided which is pivotally attached along its lower portion to the back of the frame. A clamp is located at the bottom of the handle for attaching the handle to a standard carpet kicker adjacent to the head of the kicker, so that the head will be positioned between the anchor plate and the clamp. The device functions by placing the handle upright, placing the anchor between the wall and tack strip, engaging the carpet pile with the carpet kicker head, and pivoting the top of the handle down towards the knee pad of the carpet kicker, forcing the kicker head towards the anchor, thus stretching the carpet.
