Definitions
- the present invention relates to a clamping ring for clamping covering materials, preferably floor cove ⁇ ring materials against the inner side of a draining gutter, preferably a draining gutter adapted to be mounted in a floor, whereby the clamping ring is split and compressible in radial direction against the action of a spring force which is provided, after mounting the clamping ring in the draining gutter, to dilate said clamping ring in radial direction until it engages the covering material and clamps said material against the inner side of the draining gutter.
- Clamping rings of the above type are already known from e.g. CH patent specification 461 391.
- the spring force in this clamping ring is generated while the clam- ping ring is made of a resilient material permitting it, after radial compression, to dilate or expand with sufficient force for efficient clamping of the covering material against the inner side of the gutter. Since it is the material in the clamping ring which is utilized to generate the spring force, it is necessary to design the clamping ring with varying width if it shall provide the same pressure all around and simul ⁇ taneously maintain its circular shape.
- a clamping ring with a "resilient slit" is pre ⁇ viously known from SE public specification 306 062 (fig. 8), but this clamping ring is not split but has a folded portion which possibly might serve as a type of clamping portion. Since this portion however, is not as high as the remaining parts of the ring and forms only a very small section of the ring, said ring is either hard to tighten or does not provide sufficient tensional force.
- the object of the present invention is to eliminate the problems at clamping rings of the prior art type and provide a clamping ring which is easy to stretch, which provides sufficient -tensional force within the required interval for clamping either thin or thick floor covering materials, which excludes the risks for too powerful a dilatation and which ensures as good a sealing around the entire periphery thereof.
- figure 1 is a perspective view of a part of a clamping ring of the invention disposed in the inlet por- tion of a draining gutter, whereby some portions of the clamping ring are cut away;
- figure 2 is similar to figure 1, but with the clamping ring uncut;
- figure 3 is a side view of the clamping ring of figure 1;
- figure 4 is a plan view of a portion of the clam ⁇ ping ring of figure.1 in radially compressed condition;
- figure 5 is similar to figure 4 but with the clam ⁇ ping ring stretched;
- figure 6 is a side view of the clamping ring of figure 1 before bringing together its end portions;
- figure 7 is a plan view, partly in section, of a portion of an alternatively designed clamping ring;
- figure 8 illustrates a portion of the clamping ring of figure 7 seen from the centre of said ring;
- figure 9 is a section through the clamping ring of figure 7 when disposed in a drainage gutter; and
- the clamping rings 1, 2 and 3 illustrated in the drawings are adapted to be used for clamping a cove ⁇ ring material, preferably a floor covering material 4 against the inner side 5 of a drainage gutter, prefera- bly a drainage gutter 6 to be mounted in a floor.
- the floor covering material 4 is folded down into the inlet portion of the drainage gutter and the purpose with the clamping of the covering material 4 is to prevent damages by water penetrating under the covering mate- rial.
- the clamping ring 1, 2 or 3 shown is split at one point and compressible against the action of a spring force which is adapted, after mounting the clam ⁇ ping ring in the drainage gutter 6, to dilate said clamping ring in radial direction until it engages the floor covering material 4 and clamps it against the inner side 5.
- the spring force is gene ⁇ rated by a spring means, preferably a helical spring 7, which is mounted between two end portions 8, 9 of the clamping ring.
- This helical, spring 7 is stretchable by pressing the end portions 8, 9 peripherically (arrows A in fig. 4) towards each other.
- the end portions 8, 9 are designed such that they together form an unbroken outer periphery at the parting area 10 of the clamping ring.
- said end por- tions are provided with lock surfaces 11, 12 which are adapted to engage each other and thereby prevent further separation.
- the helical spring 7 is preferably guided along a part of its length by engaging holes 13, 14 in the end portions 8, 9.
- the holes 13, 14 extend a distance into the end portions 8, 9 and run therealong in peri ⁇ pheral direction.
- the helical spring 7 extends through a space 15 between the end portions 8, 9, which space is closed at least at the upper side 16 of the clamping ring 1, 2 or 3 and at the inner side 17 of said ring in order to prevent impurities from penetrating into said space and counteract the function of the helical spring or give rise to other * problems.
- the helical spring 7 is preferably made of spring steel and its outer diameter preferably exceeds half the width of the clamping ring 1, 2 or 3. Furthermore, the outer diameter of the helical spring 7 is equiva- lent to six times its size of wire. A helical spring sized in this manner has been shown to be especially advantageous regarding sufficient tensional force and the required springing distance.
- the helical spring 7 is also dimensioned such that it generates sufficient tensional force to effi ⁇ ciently clamp covering material 4 with a thickness of 1,5 - 2,5 mm against the inner side 5 of the draining gutter 6.
- the end portions 8, 9 of the clamping ring 1, 2 or 3 preferably include peripherically directed guide portions 18, 19 which are designed to guide each other during compression or dilatation of the clamping ring.
- the guide portions 18, 19 extend peripherically and one guide portion 19 .
- the inner shank 20 cooperates with an inner guide surface 22 on the other guide portion 18 and defines an inner wall which shields the space 15 from the area 23 radially, within the clamping ring 1.
- the upper shank 21 cooperates with an upper guide surface 24 on the other guide portion 18 and defines a roof for said space 15.
- the guide portion 18 preferably has a groove 25 and the guide portion 19 a tongue inserted into said groove in order to ensure that the guide por ⁇ tions 18, 19 maintain their cooperation with each other.
- the guide portion 24 there may be provi ⁇ ded a peripheral longitudinal groove 27 with an end edge that defines the lock surface 12 of one end por ⁇ tion 8, while the lock surface 11 of the other end por ⁇ tion 9 is defined by a claw 28 extending into the groove 27.
- the outer side 29 of the clamping ring 1 has an engaging point 30 extending peripherically around the clamping ring and extending unbroken also at the end portions 8, 9 and through which said outer side engages the floor covering material 4.
- the holes 13, 14 for the helical spring 7 may be open towards the outer side 29 of the clamping ring 1 such that said spring may reach out through these ope ⁇ nings 31, 32.
- the helical spring 7 may directly engage the floor covering material 4 and affect it direct- iy.
- the clamping ring 1, 2 or 3 is preferably made such that it - before the helical spring 7 is mounted and the end portions brought in contact with each other - has an original shape wherein the end portions overlap each other to such an extent (measure C in fig. 6) that the clamping ring in its original shape has an outer diameter D lying between the diameter of the draining gutter 6 within the floor covering material 4 if said gutter has a covering material with a certain thickness, and the diameter of the draining gutter within the floor covering material if the gutter is provided with a cove ⁇ ring material with a lesser thickness.
- the clamping ring 2 shown in figures 7-9 differs from the clamping ring 1 only in a somewhat different shape of the end portions 8, 9. At the clamping ring 2, one of the end portions 9 has a substantially U-shaped profile, while the other end portion 8 has a planar pro ⁇ file and is adapted to engage the first entioned end portion 9.
- one of the end portions 9 also has a U-shaped profile, while the other end portion 8 has a planar profile.
- This clamping ring 3 differs from the clamping ring 2 in that e.g. only the end portion . 9 has a peripherically extending hole 14 into which the helical spring 7 protrudes. The other end of the helical spring 7 is here engaging the end surface 33 of the other end portion 8 instead of pro ⁇ truding into a hole also in this end portion 8.
- the clamping ring 1, 2 or 3 is mounted preferably by inserting it into the draining gutter 6 in an incli ⁇ ned position until the portion transverse to the end portions 8, 9 engages the floor covering material 4 while one hold on to the end portions 8, 9 above the draining gutter. In this way, one can lean against the draining gutter 6 when one presses the end portions 8, 9 towards each other and thus stretches the helical spring 7.
- the end portions 8, 9 are pressed towards each other until the outer diameter of the clamping ring 1, 2 or 3 is less than the inner diameter of the draining gutter 6, within the floor covering material 4, whereafter the rest of the clamping* ring 1 is brought to the intended position in the draining gutter.
- the clam ⁇ ping ring 1, 2 or 3 is released, whereby the helical spring 7 will expand said ring until it engages the floor covering material 4 around the entire periphery thereof.
- the mounting of the clamping ring 1, 2 or 3 is thus finished and it will maintain its pressure against the floor covering material 4 even if it should shrink since then the helical spring 7 will expand or dilate the clamping ring correspondingly.
- the clamping ring can be made of plastic or another suitable material and that is preferably is resilient; the clamping ring may be split at more than one location; the helical spring may be of another type of spring means mounted between the end portions; the spring means can be made of spring steel which is preferably stainless or of another suitable material; more than one spring means may be mounted between the end portions; the lock surfaces may be formed in another way than shown; the draining gutter may be adapted to be mounted in floors and include water traps or not, or may be anot ⁇ her type of draining gutter and the covering material may be of another type than floor covering material, e.g. roof covering material if the draining gutter is adapted for roofs.
