Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a protector that prevents a floor surface from being damaged by a chair leg or the like, and more specifically, relates to a protector that is difficult to peel off from a sticking site and to which dust does not easily adhere.
[0002]
[Prior art]
In recent houses, the flooring is often used because of its good design and cleanability. As illustrated in FIG. 5, the flooring floor F is formed by connecting a plurality of floor board members Fm in a planar manner by uneven fitting, and joints J are formed at the connecting portions of the floor board members Fm. It is common. Some flooring materials are made of synthetic resin and have a pseudo seam that also serves as a pattern.
[0003]
By the way, the flooring floor F is easily damaged by rubbing of chairs or table legs. Once scratched, the wound spreads out, and if it is severely damaged, it must be repaired using a dedicated repair tool. Don't be.
[0004]
Therefore, a protective device that simply protects the flooring floor F from scratches is provided, and an example is shown in FIG. The protective device 1 has an adhesive surface 21 made of a double-sided adhesive tape 3 on one surface (upper surface in FIG. 5) of a fiber base material 2 having cushioning properties such as felt, and the other surface (lower surface in FIG. 5). ) Is a protective surface 22 that contacts the flooring floor F (contacted surface), and the adhesive surface 21 is attached to, for example, the bottom surface of the leg L of the chair.
[0005]
According to this, since the protector 1 is interposed between the chair leg L and the flooring floor F, the leg L of the chair does not directly contact the flooring floor F, so that the floor surface is not damaged. .
[0006]
[Problems to be solved by the invention]
However, this protective device 1 has the following problems as it is used over time. That is, when the chair is moved, a frictional force is applied to the protector 1 in a direction parallel to the sticking surface (the arrow direction in the figure).
[0007]
As described above, since the seam J is exposed on the surface of the flooring floor F by the connection of the floor board member Fm, as shown in the enlarged view of FIG. 5, the edge of the protective device 1 is easily caught on the seam J. When a frictional force is further applied while being caught, the protective device 1 may be peeled off from the leg L.
[0008]
Moreover, even if it does not peel off, the peripheral edge of the protective device 1 may be frayed by being caught by the joint J, and dust may adhere to the frayed portion in a hairball shape, giving an unclean appearance.
[0009]
Then, this invention was made | formed in order to solve the problem mentioned above, Comprising: The objective is to provide the protector which is hard to peel off from a sticking site | part, and to which dust does not adhere around easily.
[0010]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention has an adhesive surface on one surface of a fiber base material having cushioning properties, and the other surface is a protective surface that comes into contact with a contacted surface such as a floor surface. , by sticking the pressure-sensitive surface on the leg, such as chair child, the protective surface side in contact with the contacted surface, the protector for protecting the damage to the above the contact surface, the fiber base material , unfused at least 2 consists or more mixed fibers, and rigid flange portion formed by heat-pressing the blended fibers to the periphery of the fiber substrate, a central portion surrounded by the flange including a molten fibers A cushion part made of the above-mentioned blended fiber, and the cushion part is flat on the side of the adhesive surface attached to the leg, and has a hemispherical convex shape whose height gradually decreases from the center top to the flange part. and characterized in that it is formed To have.
[0011]
According to this, since the hard flange part is formed in the peripheral edge of the fiber base material and the peripheral edge part does not directly contact the floor surface, the fiber base material is not caught by the seam of the flooring floor, for example. Moreover, since the peripheral part is heat-pressed, unraveling does not occur and dust does not adhere.
[0012]
The manufacturing method of this protective device is also included in the present invention. That is, the manufacturing method of the present invention includes a hard flange portion formed by pressing a heated metal fitting formed in an annular shape on at least two or more types of mixed fiber sheets containing molten fibers and thermocompression-bonding the molten fibers to the periphery. comprising a made from the blend fibers of the unfused to a central portion surrounded by the flange portion, the cushion portion thereof that height as the central top portion toward the flange portion formed at gradually lower hemispherical convex It is characterized by obtaining protective equipment having
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a protector according to an embodiment of the present invention, and FIG. 2 is a sectional view thereof. FIG. 3 is a cross-sectional view of a state in which the protective equipment is attached to the leg L of the chair.
[0014]
The protective device 10 has an adhesive surface 21 on one surface (lower surface in FIG. 2), and the other surface (upper surface in FIG. 2) is a protective surface 22 that contacts a contacted surface such as a floor surface The base material 20 is provided, the hard flange part 23 is formed in the periphery of the fiber base material 20, and the cushion part 24 is provided in the center part enclosed by the flange part 23. As shown in FIG.
[0015]
In addition, the release paper 30 which protects the adhesive surface 21 when not in use is provided on the adhesive surface 21 side of the fiber base material 20. The release paper 30 may be the same as the separator used for, for example, a double-sided adhesive tape.
[0016]
The fiber substrate 20 is made of at least two or more kinds of blended fibers including melted fibers. For the melted fibers, for example, low melting point polypropylene is used. As the fibers blended with the melted fibers, resin fibers such as polyester and cotton yarns are used. Natural fibers such as can be used.
[0017]
In this embodiment, the fiber base material 20 is composed of a blended ratio of molten fiber (low melting point polypropylene): resin fiber (polyester) = 30: 70, but it is desired to further improve the adhesive strength between the fibers. In such a case, it is sufficient to increase the blending ratio of the molten fiber, and the blending ratio can be appropriately changed according to the specifications of the protective device 1. Various pigments and various additives may be further added.
[0018]
The flange part 23 can be formed by crimping a heating metal fitting to the peripheral part of the fiber base material 20. In this embodiment, the flange portion 23 is formed in a circular ring shape around the hemispherical convex cushion portion 24, but may be formed in a square shape in addition to this and fixed by heat fusion. If it is made, the shape is not particularly limited.
[0019]
The cushion portion 24 is made of unfused blended fibers left in the central portion surrounded by the flange portion 23, and swells in the direction of the floor surface F as shown in FIG. In this embodiment, the cushion part 24 is formed in a hemispherical shape so that the height gradually decreases from the central top part toward the flange part 23 side.
[0020]
In this embodiment, although the adhesive surface 21 consists of the double-sided adhesive tape 40 affixed with respect to the fiber base material 20, the adhesive agent may be apply | coated. In any case, the adhesive surface 21 is preferably protected by the release paper 30 when not in use.
[0021]
Next, with reference to FIG. 4, the suitable manufacturing method of the protector 10 is demonstrated. First, a blended fiber sheet 10M formed in a felt shape having a size capable of taking a large number of protectors 10 is prepared, and an annularly formed heating metal fitting H such as a washer ring is arranged at a predetermined interval.
[0022]
Then, a hot press (not shown) is applied from above, and the mixed fiber sheet 10M is pressurized and heated through the heating fitting H. As a result, the melted fiber of the portion pressed by the heating metal fitting H is hardened to form an annular hard flange portion 23, and the unfused blended fiber is left inside the cushioned portion surrounded by the flange portion 23. 24 will be formed. After the heat pressing, the protective device 10 is cut out from the blended fiber sheet 10M individually.
[0023]
In the above manufacturing method, the heating metal fitting H made of a washer ring is simply adopted. However, it goes without saying that the heating metal fitting H may be formed integrally with a heating press mold (not shown).
[0024]
In order to use this protector 10, the release paper 30 shown in FIG. 1 is removed from the fiber base material 20, the double-sided adhesive tape 40 is exposed, and is attached to the bottom surface of a leg L such as a chair via the double-sided adhesive tape 40. That's fine.
[0025]
According to this, as shown in FIG. 3, only the convex spherical cushion portion 24 comes into contact with the floor surface F, and the peripheral flange portion 23 is lifted from the floor surface F. Even if it catches on the joint J of the floor surface F, there is no possibility of peeling off from the end.
[0026]
In addition, since the rigidity of the entire fiber base material 20 is enhanced by the hard flange portion 23 formed on the periphery of the cushion portion 24, the frictional force with the floor surface F can be evenly distributed to the legs L of the chair. More difficult to peel off. Furthermore, since the hard flange part 23 is formed in the periphery, it is hard to fray the periphery and it is hard to adhere dust.
[0027]
Although the said embodiment demonstrated the example which mounted | wore the leg L of the chair with the protector 10, of course, you may apply to legs, such as a table and a sofa. Further, the overall shape of the protective device 10 may be arbitrary, and various modifications such as a quadrangle and a triangle are possible in addition to a circle.
[0028]
【The invention's effect】
As described above, according to the present invention, the cushion portion is formed in a convex spherical shape by leaving the molten fiber in an unfused state in the approximate center of the fiber base composed of the blended fiber of the molten fiber and the resin fiber. And by providing a flange portion that is arranged so as to surround the cushion portion and the molten fiber is hardened in a plate shape by heat fusion, it is possible to reliably prevent peeling off from the sticking site due to frictional force, Moreover, since the end portion is not frayed, a protective device that does not attach dust or the like is provided.
