Abstract: A multifunctional and modular combined doormat includes a basic mat and a functional mat. The basic mat has two abutting edges of its topside respectively fixed with numerous positioning lugs spaced apart equidistantly and respectively bored with a positioning hole, and the other two abutting edges of its underside respectively disposed with numerous position projections spaced apart equidistantly and corresponding with the positioning holes. Two or more basic mats can be combined together by mutual engagement of the positioning holes and the position projections. The functional mat is assembled on the basic mat, having special functions. Thus, a multifunctional and modular combined doormat is made by combining the basic mats with the functional mats.

Abstract: A combinable floor board includes a square body made of plastic. The body is provided with an L-shaped upper connecting side extending from an upper section of two adjacent sides, and an L-shaped lower connecting side extending from a lower section of other two adjacent sides. The upper and the lower connecting side have the same width. The upper connecting side has a plurality of female fitting members, and the lower connecting side has a plurality of male fitting members to correspond to the female fitting members. Thus, one floor board can be assembled with another floor board by fitting together the upper connecting side with the lower connecting side. So a large number of the floor boards can be assembled on a large area of the ground with fastness, convenience and a decent appearance.

Abstract: A plastic product with a long-term dispersion of fragrance consists of a main body made of a plastic compound and plural aromatic master batches. The aromatic master batches are kept properly spaced apart in the main body to remain grainy as they are, able to keep dispersing fragrance for a long period of time.

Abstract: A curtain including a fixing rod and a curtain body. The fixing rod is secured to an upper side of a window frame and includes a winding shaft located on an interior and an endless bead string movably wound on one end of the winding shaft. The curtain body is made of a plurality of flexible strings intertwined with one another to form a plurality string circles and pores of various sizes between the string circles. The upper end of the curtain body is fixed on the winding shaft so that the curtain body may be moved up and down by rotation of the winding shaft by pulling the bead string. The pores let the curtain body have a predetermined airiness and allow light to pass through.

Abstract: A ventilating shoe pad includes a pad body made of plenty of elastic fiber that is loosely and separately interwound together, with numerous gaps formed among the interwound fiber. The pad body is formed by thermal compression with a protective edge slightly extending upward obliquely at the peripheral edge corresponding to the recessed portion and the heel of a user's foot. The ventilating shoe pad of this invention has good permeability and good elasticity, safe and comfortable in using.

Abstract: A curtain includes a fixing rod and a curtain body. The fixing rod is secured at an upper side of a window frame, consisting of a winding shaft in its interior and an endless bead string wound movably on one end of the winding shaft. The curtain body is made of a plurality of flexible strings intertwined with one another to form innumerable string circles and pores of various sizes between the string circles. Then the upper end of the curtain body is fixed on the winding shaft so that the curtain body may be pulled up and down by rotation of the winding shaft by pulling the bead string. The pores functions to let the curtain body have proper airiness and light passing through.

Abstract: In a process for making a porous drainage medium composed of entangled strands of thermoplastic resin, subsequent to forming a tubular preform, the preform is formed with necked-down sections at intervals along the length thereof before proceeding to a cooling tank. As such, the drainage medium can be flexed in the cooling tank and can be discharged continuously and conveniently out of the cooling tank without being cut.

Abstract: A disfigure-resistant plastic-string mat includes a scraping layer and a lattice-shaped layer fused under the scraping layer. The scraping layer is made of plastic elastic strings formed randomly and irregularly into piled up countless rings interlocking an intercrossing with one another to define countless gaps. The lattice-shaped net layer is woven of fiber of high strength and fused with the scraping layer by means of immersion in plastic solution homogeneous with the scraping layer under high temperature, and firmly combined with the scraping layer after cooled so that the scraping layer may not easily shrink or lengthen, constricted by the lattice-shaped net layer.

Abstract: A double-layer sandal includes a sandal sole, a sandal top, a basic layer, a first netted layer and a second netted layer. The first netted layer is combined on the sandal sole, made of much plastic elastic thread interwoven together forming lots of solid and irregular rings, with numerous gaps formed among the elastic thread. The second netted layer combined on the first netted layer is made of a great deal of plastic elastic thread interwoven forming a great many solid and irregular rings, and having numerous gaps formed among the elastic rayon. The second netted layer has a smaller thickness, greater density and smaller gaps than the first netted layer. The first netted layer has great elasticity and good effect of ventilation and water penetration, and the second netted layer has a flat surface.

Abstract: A seashore sandal includes a body which has drain holes and grooves in a recessed top chamber thereof and two recessed bottom chambers, an insole made of plastic wires and fastened to the recessed top chamber at the top side of the body, and two bottom blocks made of plastic wires and respectively fastened to the recessed bottom chambers at the bottom side of the body. Sands are carried away from the top side of the body through the grooves and the drain holes to the bottom side of the body when water is applied to the top side of the body.
