  • Combination floor pad having composite base boards
    Patent number: 6694691
    Abstract: A combination floor pad includes at least one base pad, and a plurality of composite base boards fixed on the base pad. Thus, the base boards can be securely locked in the base pad rigidly and stably, thereby preventing the base boards from being detached or loosened from the base pad. In addition, the base boards can be closely secured by the side ribs and the positioning ribs, so that dirt or dust is not deposited between the base boards easily, thereby facilitating the user cleaning the base boards.

  • Combination floor pad having composite base boards
    Publication number: 20030136070
    Abstract: A combination floor pad having composite base boards includes at least one base pad, and multiple base boards fixed on the base pad. The base pad has a surface provided with two adjacent side ribs, and provided with multiple positioning ribs arranged longitudinally and transversely in a staggered manner, thereby forming multiple receiving spaces in the base pad for insertion and placement of the base boards. Thus, each of the base boards may be securely locked in the base pad rigidly and stably, thereby preventing each of the base boards from being detached or loosened from the base pad.
