  • Publication number: 20090057629
    Abstract: A positioning unit of a carpet kicker having a housing with a rear end having a receiving element into which a 7-shaped hook member is engaged. The 7-shaped hook member includes a shorter internal portion for engaging into the receiving element in place and a longer external portion for leaning against a wall in an upright state. A flat hook portion is formed at the bottom of the external portion. The 7-shaped hook member includes a plurality of strengthening ribs that are arranged in a non-flat and parallel manner in a vertical direction. In this way, a more convenient human machine operation interface is ensured. Moreover, it is avoidable that an inclined position is created by a single point reacting force during the operation of the kicker. Accordingly, the carpet may be smoothly pulled and spread on the floor in place.
