Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a filling material that is fitted into a non-slip fitting frame for a building, which is used by being fixed to the tip of a stair tread.

Specifically, a plurality of rigid materials coated with a synthetic film and made of a material with an appropriate shape and a low expansion/contraction rate are buried arbitrarily in the longitudinal direction within the thickness of the non-slip filling material for buildings, and are fixed and integrated to prevent expansion and contraction. It is a non-slip filling material for buildings.

Conventionally, this type of non-slip filling material for buildings uses a film of vinyl chloride resin or other synthetic resin, so the filling material hardens, shrinks, softens and expands due to temperature changes.
As a result, a gap is created between the metal fitting frame to which the filler is fitted, impairing the aesthetic appearance, and preventing the intrusion of sewage and dirt from both shrunken ends. The filling material may come off from the fitting frame, and it is also a very dangerous situation from the standpoint of ensuring the safety of stairs users.

Many techniques have already been provided in order to solve the drawbacks and problems included in the conventional techniques. However, when considered from a technical standpoint, there are many problems, and the current situation is that a product with sufficient product value has not yet been provided. For example, in the old days, Jikko 6-46
0 (In No. 11, there is a anti-slip device in which "a wire mesh or perforated plate is interposed within a rubber plate and a piece of cloth is attached to the back side." Or, by interposing a perforated plate, the whole structure can be made solid and retain its form, and even when it is attached to a staircase, it becomes a wire mesh core and prevents it from coming off when nailing. In addition, in Japanese Patent Publication No. 50-14454, a non-slip fitting frame for buildings is provided with ``a non-slip filler in which a rigid strip plate is integrally interposed in the longitudinal direction of the inside. technology is provided.And,
According to the description in the detailed description of the invention in the specification, the term "rigid strip plate" here is considered to mean "reinforced plastic impregnated with metal or fiberglass, etc." . However, even if such a rigid band-shaped plate such as a metal plate can be integrally interposed during extrusion molding, it is technically insufficient to firmly integrate the two, and in the specification, applicant Yama et al. As expressed above, if there is a drawback that the expansion of the filling material cannot be prevented unless the rigid band-shaped plate is left long at both ends and bent and hooked to both ends of the non-slip metal base, then the Even with the latest technology, it is insufficient, and it can be said that no countermeasures have been added to the technology to deal with the shrinkage of the filler in winter. Furthermore, Special Publication No. 50-17765 and Special Publication No. 49-418
In No. 55, in the longitudinal direction inside the filler, [a non-slip filler in which a rigid band-shaped plate having acute-angled fishing pieces is embedded integrally on both lateral edges], and [- or a plurality of pieces] "A non-slip filler with an integrally interposed anti-expansion strip made of a linear body", "an anti-slip filler integrally interposed with an anti-expansion strip made of a rod-shaped body with numerous unevenness formed in the longitudinal direction of the outer circumferential surface"; [Anti-slip filler in which an anti-expansion strip made of a rod-shaped body with a number of concave portions provided on the outer circumferential surface is integrally interposed in the longitudinal direction of the inside thereof] '', ``Anti-slip filling material with a spiral anti-expansion strip interposed integrally in the longitudinal direction'', etc. have been announced. However, what all of these conventional technologies have in common is that they involve embedding anti-expansion materials having various appropriate shapes within the thickness of the non-slip filler made of synthetic resin such as vinyl chloride resin. , I don't think it's wrong. However, interposing the anti-expansion material inside the synthetic resin filler does not immediately mean that the two are completely fixed and integrated. That is, it can be said that this does not directly lead to prevention of expansion and contraction. Furthermore, even if attempts are made to increase the joint area with the synthetic resin filler by giving the anti-expansion material various shapes as in the prior art, this alone will never increase the anti-expansion effect. It is impossible to achieve this. In an extrusion molding machine, an anti-expansion material is interposed inside the filling material, and even though it appears temporarily integrated when extruded, it is difficult for both to be attached to the stairs during construction. are usually completely separated.

Therefore, the present inventor investigated the root causes of the problems of the prior art as described above, and investigated the fixed bond between the non-slip filling material for buildings and the anti-expansion material buried and integrated inside the non-slip filling material. As a result of extensive research in search of the cause of this problem, we found that by coating a rigid material made of aluminum, which is an anti-expansion material, with a synthetic resin film, we were able to bond the aluminum material and the synthetic resin filler. We have already provided a technology that has succeeded in making the filling material extremely dense, making it possible to completely fix and integrate it, and completely preventing expansion and contraction of the entire filling material (
Special Publication No. 56-16827).

The claimed invention is based on the invention developed by himself (Japanese Patent Publication No. 56-1
No. 6827), this is a further improvement. That is, the purpose of the present invention is not only to prevent the expansion and contraction of the filling material itself that fits into the non-slip fitting frame for buildings, but also to improve the ease of work when fitting the filling material to the fitting frame. We will also pursue this. In other words, as can be seen from Fig. 4, in the actual fitting process between the filler and the fitting frame, the filler must be fitted into the frame while bending both edges of the filler with your fingers. If the rigid material embedded and integrated within the thickness of the filler is, for example, a wide plate, the efficiency of preventing expansion and contraction of the filler will be increased, but the fitting operation while bending with fingers will increase. The work was extremely time-consuming and inefficient. Therefore, in the present invention, the fitting work is made very easy, and since a plurality of arbitrary rigid members are embedded and integrated within the thickness of the filler, the expansion and contraction prevention effect of the filler itself is sufficiently improved. It is something that can be demonstrated.

Hereinafter, the present invention having such characteristics will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a base material 1 showing an embodiment of the present invention, and the base material 1 as a filler is a non-slip filler for buildings made of vinyl chloride resin, acrylic resin, urethane resin, synthetic rubber, etc. On its surface, a plurality of uneven grooves 2 for preventing slipping are formed along the longitudinal direction of the filler, and even though the back surface is flat, the grooves 2 are formed along the longitudinal direction of the filler. It may be formed into Forming the groove makes it easier to fit the filler into the fitting frame 4,
.

Moreover, it has the effect of enhancing the stepping feeling. In addition, notch grooves and the like are formed on both longitudinal edges 5 and 6 of the filler material in order to facilitate fitting and disengaging with the fitting frame 4 and to prevent it from coming off during use. to strengthen the integration of In the present invention, a rigid material 3 is coated with a synthetic resin film, an example of which is shown in FIG.
Bury it and fix it into one piece. In the present invention, in this case, a plurality of rigid members 3, for example, two or three, are arbitrarily prepared and embedded and integrated within the thickness of the filler 1. The reason for this is to pursue ease of fitting into the fitting frame 4 as described above, and to also exhibit the effect of preventing the filler 1 from expanding and contracting.

When the rigid material 3 is configured as in the present application, as is clear from FIG. We can work together. The rigid material 3 here is not limited in its shape and can be of any suitable shape, but from the viewpoint of being an anti-expansion material, it is important to select and use a material that has a low expansion/contraction rate due to temperature differences. be. The thickness of this rigid material 3 depends on the material used, but for example, if aluminum material is used, a thickness of approximately (1.05 mm) can be used; It is not a strict idea, but should be considered based on the need for ease of deformability.

The present invention consists of the above-mentioned structural requirements, and is an inset type non-slip device for the purpose of preventing expansion and contraction of the filler.
Since arbitrary plural rigid materials are buried in the longitudinal direction within the thickness of the filler using a synthetic resin coach, they can be buried within the thickness of the filler using the heating and pressurizing process that inevitably accompanies extrusion molding. In addition to making the bond with the rigid material extremely tight, the product after extrusion can be rolled up and cut very easily without peeling. Furthermore, in the claimed invention.

Rather than using a single wide plate-shaped rigid material to be buried in the filling material, multiple arbitrary pieces of rigid material are buried, making the fitting work to the fitting frame extremely easy. It was a success. In this way, it exhibits many characteristic effects such as being able to be easily attached to and detached from the fitting frame, and is similar to the rigid material inside the filler, which has been experienced in the conventional technology where the rigid material is simply inserted. Sewage and
The present invention is not only a non-slip filling material for buildings to prevent expansion and contraction, but also has secondary effects such as eliminating factors that allow the infiltration of dust.
