Description

[Detailed description of the invention] ``Fixed ring The present invention provides a covering, preferably a floor covering, which is installed in a drain, preferably on a floor. This invention relates to a fixing ring for fixing to the inside of a drainage ditch. The fixed ring is After installation in the drain, it expands until it engages with the sheathing and secures the sheath to the inside surface of the drain. It is divided radially so that it can be tensioned and compressible against the action of an applied spring force. It has a structure that

Fixing rings of the above type are described, for example, in Swiss (Cl{) Patent Specification No. 461,391. Already disclosed in the issue. The spring force in this fixed ring is due to the elastic material. This occurs as long as the spring is manufactured from The extension provides sufficient force to effectively secure the dressing to the inner surface of the groove. Spring The force is generated by the material used for the fixing ring, so it is uniform throughout the area. If you want to apply a certain amount of pressure and at the same time maintain its circular shape, you need different widths. It is necessary to design a fixed ring with

However, if the fixed ring is formed with different widths, the ring The tensile force in the narrow part is significantly lower than that in the wide part. A problem arises. This means that the retaining ring will maintain the same clamping force even after several years of use. Considering the importance of maintaining tensile force, this is naturally not preferable.

``A fixing ring with an elastic slit J is disclosed in the Swedish (SE) published patent specification. No. 306.062 (see No. 8), this fixed ring is undivided and has a folded part that probably acts as a kind of clamp. have. However, this part is not high compared to the rest of the ring. , and since it forms a very small cross-sectional part of the ring, the above ring is difficult to firmly clamp and cannot apply sufficient tensile force.

It is an object of the present invention to eliminate such drawbacks of fixation rings in the prior art and to provide: 1) distraction 2) Sufficient tensile force is required to hold the floor covering material, regardless of its thickness. 3) prevent excessive tension on the ring, and 4) apply it to the entire periphery of the ring.
