Abstract: A protrusion of the plug lid out of a bath tub is restricted to prevent the plug lid from being a hindrance, and water-tightness of the plug is improved. The plug lid is dropped into a notch formed in such a way that the circumferential edge of the plug lid becomes lower than the bottom surface of the bath tub. The packing closely contacts a packing close-contact surface narrowed from the bottom surface of the notch in a downward direction. The bottom part of the notch is formed into the horizontal plane and the plug lid is supported while it is not inclined under application of weight (such as a hydraulic pressure or an artificial pressure applied by a user) and the packing is protected from unnecessary crushing force.

Abstract: A protrusion of the plug lid out of the bath tab bottom part is restricted to reduce a possibility in which the plug lid becomes a hindrance and a water-tightness at the plug is improved. The plug lid is dropped into the notch formed in such a way that the circumferential edge of the plug lid becomes lower than the bottom surface of the bath tab. The packing is closely contacted with the packing close-contact surface narrowed from the bottom surface of the notch in a downward direction. The bottom part of the notch is formed into the horizontal plane and the plug lid is supported while it is not inclined under application of weight (a hydraulic pressure or an artificial pressure applied by a user) and a non-required crushing force is prevented from being acted on the packing.

Abstract: There is provided a stable drain plug device in which main bodies (the plug lid and the ascending or descending member) are not floated under a pushing operation of the operating part.

Abstract: A drainage plug to be used in a bathtub, a basin or the like, wherein the plug is provided with a mechanism for opening or closing a plug cap every time a direct contact of a user with the plug cap through a user's foot or hand is performed. A foot or manual depressing action is applied and a depressing of the plug cap opens or closes the plug.

Abstract: A novel decorative panel comprises specified rigid decorative sheets replaceably installed on a structural support such as frame works, substrate boards or walls. Such decorative sheets can be readily installed or replaced by the use of removable fixing means such as screws. The decorative sheet is characterized by cutouts at the corners thereof and depressions adjacent to the cutouts. When four decorative sheets are assembled together, the assembled corners of the sheets form a cut-out hole where a fixing means is inserted and a depression around the hole where the head of the fixing means is recessed. By utilizing the heads of fixing means, a variety of decorative accessories or articles can be further set on the decorative panel by means of pins, hooks, rods or magnet pieces.

Abstract: A draining plug device includes a plug lid which opens and closes a draining port and is installed on a support provided in a water drainage cylinder, a remote operating portion which is directly connected to the support and the plug lid by means of a flexible wire-like connection, and an opening and closing holding mechanism which provides guidance and support so that an operational force generated by pushing down on the remote operating portion is transmitted to the support and the plug lid. The plug lid can be alternated between an opened state and a closed state by pushing down on the operating portion.
