Description

[Detailed description of the invention] The present invention enables the selection of two or more molds using one mold, and satisfies the diverse needs of users, and reduces inventories of manufacturers and raw materials. The purpose is to reduce losses.

Generally, the shape of the tread part of a single stair mat is limited to one shape, such as a square shape or a semicircular shape, and especially in the case of a semicircular shape, the carpet used is cut into a semicircular shape and the remaining part is used. The loss rate of raw materials is high because they are discarded. On the other hand, users desire various types and colors such as semicircular shapes, square shapes, etc., and in order to satisfy these desires, it is necessary to maintain at least a certain level of inventory of all shapes and colors.

The present invention uses two or more molds in combination for the tread mat part, as shown in the example shown in Fig. 3, and the outer mold surrounding the semicircular mat 2 to be merged has a quadrangular shape. The merging mats 1 are combined to form a single stair mat, which serves both as the semicircular mat in FIG. 1 and the square mat in FIG. 2. That is,
The conventional square pine shown in Figure 2 has an edge width of 5 mm or more.
Cut the merging mat 2 that is about 20 mm smaller. Cut the merging pine 1 having a square outer shape with the width of the edge shown in 3, combine the merging pine 2, and apply thermoplastic material such as vinyl chloride 6 from the back side. The resin is laminated, glued or sewn, and the edge width 3
The vinyl chloride is cut along the intermediate line 4 to separate the merging mat 2 and the merging mat 1. Next, as shown in the back view of the figure, both the merging mat 2 and the merging mat 1 are adhered without any gaps using an adhesive tape 7 or the like from the back side 6 of the vinyl chloride to integrally connect them into one mat.

The edge width 3 of the merged pine 2 and the merged pine 1 exposes vinyl chloride, etc. 6, which may damage the appearance of the interior decoration. It is also possible to add a border decoration to the edge of the semicircular pine 2 to be merged, and then attach the merging pine.

Therefore, when the staircase is used in a circular staircase structure, the depth dimension on one side of the tread surface becomes smaller as shown in Figure 4, so in the case of conventional square stair mats, the part shown by the dotted line on the left shoulder is cut. However, if the stair mat of the present invention is used, it can be easily installed by removing the merging mat 1 and using only the circular merging mat 2. Depending on the user's preference, it is possible to choose from two ways of use: attaching the merging mat 1 to make it square, or removing the merging mat 1 to create a semicircular pine. Larger than normal stair tread area,
For example, if you take the size of about 25cm x 75cm and cut the merging pine 1 according to the dimensions of the treadboard and use it together with the merging pine 2, you can lay the pine over the entire treadboard without any gaps, making it suitable for the winter season. It is also possible to use only the merged pine 2 for the summer season.

Furthermore, if the colors, materials, designs, and surface shapes of the merging mats 2 and the merging mats 1 are made different, various combinations can be made by changing the combinations of the two. Both shapes are not necessarily limited to semicircular and square shapes; for example, various variations as shown in Fig. 5 are possible, and not only two shapes but a combination of two or more shapes can also be used. be.

Since the back side is made of flexible rubber, synthetic rubber, vinyl chloride, etc., it adheres closely to the tread surface and the connecting parts will not turn over or shift.

Claims (1)

[Scope of utility model registration request] A stair carpet with approximately the size of a stair tread, which is made by laminating, gluing, or sewing rubber, synthetic rubber, or thermoplastic resin such as vinyl chloride on the back side of a carpet made of synthetic fibers or natural fibers, has an area larger than most of the tread. It is separated into two mats: a mated mat having an arbitrary shape that occupies the central part, and a merging mat into which approximately half the circumference of the mated mat is inserted. It is inserted in the half circumference part of the mat, and the two mats are integrated with adhesive tape etc. from the back side,
A stair mat in which only the merging pine can be used or both the merging and the merging pine can be used.
