Description

[Detailed description of the invention] This invention relates to a mat edge frame.

1 and 2 show external views of examples of mats conventionally used for purposes such as dustproofing floors.

Conventionally, this type of mat has a tertiary mat so that it does not easily roll over or move even when subjected to external forces such as being stepped on or kicked carelessly, in other words, to provide stability.
Under the mat 1 as shown in the figure, an underlay 3 made of a flexible material such as rubber and having a structure as shown in FIG. 4 is usually placed side by side.

The relationship between the mat 1 and the underlay 3 used in this way is as follows:
As shown in FIG. 5, which shows the AA cross section of FIG. 1, a mat 1 is placed on an underlay 3 having an edge 4, and these are placed on a floor surface F.

The first problem with this conventional structure is that the mat 1 shrinks due to washing or aging, and as shown in FIG. There are gaps between the walls, and dust accumulates in these gaps, spoiling the aesthetic appearance.

The second problem is 1. Mat 1 in the area where the gap is
A part of the paper may lift up, and this raised part may be particularly susceptible to wear, and the raised part may be turned over when subjected to external force such as being kicked.

The third problem is that the sum of the thickness of the pine tree 1 and the thickness of the underlayment 3 is at a height that protrudes from the floor F, making it easy to kick.

Moreover, the fourth problem is that the cost of the underlay 3 is high.

Examples include.

This invention attempts to solve or improve each of the problems in the conventional devices.

This invention will be explained based on the drawings.A cloth fastener (commonly known as Velcro) pile side 2 is attached around the mat 1 as shown in FIG. An edge frame 5 having a cloth fastener hook side 6 on the downward surface of the frame body is fitted and assembled as shown in the external view of FIG.

The AA cross section in FIG. 1 is as shown in FIG. 9, and the situation when not combined in this way is as shown in FIG. 10.

11 and 12 show a structure in which the cloth fasteners 2 and 6 are arranged above the ends of the mat 1. FIG.

In this way, instead of the conventional method of placing the mat 1 on the underlay 3 having the edge 4 (the edge frame 5 is fitted around the mat 1, and the fabric fasteners 2 and 6 are used to secure the mat 1 tightly) By using this method, even if the mat 1 has shrunk a little due to washing, etc., the mat 1 can be stretched 7 and there is no gap between it and the edge frame 5. can be definitely combined with.

In addition, since the product of the present invention does not have a base portion unlike the conventional product, the height corresponding to its thickness is reduced. Moreover, the amount of material corresponding to the underlying portion was reduced.

As described above, all of the problems with the conventional methods listed at the beginning have been resolved or significantly improved.

However, in this invention, in order to further increase added value,
There is a technique explained below.

If the size of the edge frame 5 is larger than a certain level, there is a risk that the edge frame 5 will become meandering due to lack of self-restorability, as shown in FIG. When the mat 1 is combined with the edge frame 5, the appearance becomes aesthetically unsatisfactory. Furthermore, if the degree of shrinkage or deformation of the mat 1 exceeds a certain level, the mat 1 and the edge frame 5 will be forced together, and as a result, the edge frame 5 will follow the deformation of the mat 1. It is not aesthetically pleasing because it is assembled based on the shape.

As a means to avoid such a situation, the structure of the edge frame 5 is changed to a material with rigidity and elasticity such as a thin copper strip, as shown in FIG. 14 showing the BB cross section of FIG. Aggregate 7 with high properties is added, and as a result, the restorability of the edge frame 5 is extremely improved.

15 and 1 are methods for manufacturing the edge frame 5 at a low cost while being able to accommodate as many different shapes of the mat 1 as possible.
As shown in Fig. 6, the linear frame members and curved frame members constituting the edge frame 5 are individually molded, and these are connected at the points indicated by the connecting portions 8. .

Furthermore, in order to form the series of mats 1 so as to lie along a floor surface with a step such as a staircase, the edge frame 5 is
This becomes possible by adding a vertically bent frame member as shown in FIG.

In this way, by freely selecting various partially molded frame members and combining them by adhesion or fitting, it is possible to construct a series of edge frames 5 in a wide variety of ways. In addition to being able to meet various shape requirements, it also has the following features:

In the conventional method, since the underlay is integrally molded, a mold for molding the underlay of a type corresponding to the type of the shape of the mat is required.

However, according to the present invention, edge frames of a wide variety of shapes can be manufactured by simply preparing dies for drawing and forming straight frame members and various molds for forming curved frame members. In addition, the size of the mold for molding the mold is much smaller than that of the conventional method, so naturally the mold cost is low, and the frame as a product can be made more easily. In addition, the mold depreciation rate is also lower, which naturally makes it possible to produce mat edges with high added value at low cost.
