Title: Vibration-isolating insert
The present invention relates to a vibration-isolating insert, preferably of elastomeric material, for a pipe clip for attaching a pipe to a wall, ceiling or other support, the vibration-isolating insert being adapted to bear against an inner circumference of a substantially annular pipe clip body and ultimately - in use - to be positioned between the outer 5 circumference of the pipe and the pipe clip body, the vibration-isolating insert comprising an elongate strip of vibration-isolating material which is provided with gripping formations integrally formed with the strip for gripping the lateral edges of the pipe clip body and furthermore having a pipe clip facing side and a pipe facing side.
EP 413 883 discloses several vibration isolating insert for a pipe clip with a metal 10 pipe clip body. The sound-insulating insert is formed by a C-shaped rubber profiled section which grips around the pipe clip body. The sound insulating insert has protuberances or longitudinal ribs.
In US 3 606 218 a vibration isolated pipe clip is disclosed which is provided with vibration isolating transverse strips cemented to the pipe clip body and an elastomeric layer 15 that is applied by dipping or spraying. The transverse strips which are made of rubber are encapsulated by the elastomeric layer.
In US 4441677 a vibration isolating insert for a clamp for mounting and restraining wires, wiring conduit and similar structures. The insert has on its inner side integrally molded needle-like protruberences.
20 The present invention has for an object to provide an improved vibration isolating insert which is relatively easy to manufacture.
This object is achieved by a vibration-isolating insert according to the preamble of claim 1, wherein the pipe facing side has a plurality of longitudinal ribs which are serrated along their length.
25 The serrated ribs provide the advantage that the vibration-isolating insert can be applied in pipe clips for pipes with a relatively small outer diameter of e.g. 10 - 22mm. The serrations prevent that in the top region of the ribs a large compression force is caused, through which the strip would tend to unbend.
In a possible embodiment each of the serrated ribs comprises consecutive teeth and 30 indents with a trapezoidal section seen in the transverse direction of the strip.
Preferably, the indents have a depth which corresponds to the heigth of the longitudinal ribs with respect to the pipe facing side of the strip.
-2-
The invention furthermore relates to a vibration-isolating insert for a pipe clip for attaching a pipe to a wall, ceiling or other support, the vibration-isolating insert being adapted to bear against an inner circumference of a substantially annular pipe clip body and ultimately - in use - to be positioned between the outer circumference of the pipe and the 5 pipe clip body, the vibration-isolating insert comprising an elongate strip of vibration-isolating material which is provided with gripping formations integrally formed with the strip for gripping the lateral edges of the pipe clip body and furthermore having a pipe clip facing side and a pipe facing side, wherein the pipe facing side has transverse ribs formed on it, which extend in a transverse direction of the strip.
10 The tranverse ribs have between them a intermediate space, which prevents that in the top region of the ribs a large compression force is caused, through which the strip would tend to unbend. The vibration-isolating insert can thus advantageously be applied in pipe clips for pipes with a relatively small outer diameter of e.g. 10 - 22mm.
The transverse ribs may extend at right angles with the longitudinal axis of the strip. 15 Alternatively, the transverse ribs may extend slanting with respect to the longitudinal axis of the strip, preferably at an angle between 20° - 90°, most preferably at an angle of 45°.
In the vibration elements according to the invention the gripping formations may in one possible embodiment be L-shaped members which are formed at either lateral sides of the strip. The L-shaped member has a first leg which extends along the lateral edge of 20 thepipe clip body and the other edge extends from the first leg inwardly, such that the L-shaped gripping members each grip around a lateral edge of the pipe clip body.
In another possible embodiment the gripping formation may be formed by a leg which extends from the strip along the edge of the pipe clip body. The intermediate space between the legs is such that the legs each engage one of the lateral edges of the pipe clip body and 25 clamp the clip body between them due to resilient deformation of the legs.
The invention also relates to a method according to claim 9 according to which an elongated strip is extruded with gripping formations integrally formed with the strip for gripping the lateral edges of a pipe clip body by extruding a melted elastomer through a extrusion head, wherein downstream of the extrusion head the extruded strip is pressed with 30 at least one side against a rotating gear wheel such that the profile of the gear wheel is pressed in the still warm extruded strip material and forming transverse indentations in said side.
The method according to the invention provides an efficient and cost effective way to manufacture an insert for a pipe clip. From the prior art methods are known where 35 protruberances are integrally moulded on a vibration isolating strip for a pipe clip, but these products are manufactured by injection moulding, which is a more complex and time -3- consuming manufacturing method than extrusion for manufacturing strip-like material. Furthermore, the injection mould is relatively expensive tool to make.
In a preferred embodiment the gearwheel used in the method has teeth with a substantially tapezoidal cross-section.
5 The invention will be described in more detail in the foilwing description with reference to the drawing, in which:
Fig. 1 shows a view in perspective of a piece of a vibration-isolating insert according to the invention,
Fig. 2 shows a cross section of the insert of Fig. 1, 10 Fig. 3 shows a section through the line A - A in Fig. 2,
Fig. 4 shows a schematic view of the manufacturing of a vibration-isolating insert according to the invention,
Fig. 5 shows a view in perspective of another embodiment of a vibration-isolating insert according to the invention, and 15 Fig. 6 shows a view in perspective of yet another embodiment of a vibration-isolating insert according to the invention.
In Figs 1 - 3 is shown a vibration-isolating insert 1 for a pipe clip in different views. The vibration-isolating insert 1 is adapted to bear against an inner circumference of a 20 substantially annular pipe clip body and ultimately - in use - to be positioned between the outer circumference of the pipe and the pipe clip body. Such a pipe clip body is made typically of metal, but may be made of plastics material or another suitable material as well.
The vibration-isolating insert 1 is preferably made of rubber or another elastomeric material. Although not preferred at this moment, also other vibration isolating material is 25 thinkable.
The vibration-isolating insert 1 comprises an elongate strip 2 having a pipe clip facing side 3 and a pipe facing side 4. In use the pipe facing side 4 faces the pipe arranged in the pipe clip, and the pipe clip facing side 3 bears against the pipe clip body.
There are gripping formations 5 extending from the lateral edges of the strip 2. The 30 gripping formations 5 have in cross section generally an L-shape with one leg 5a extending substantially perpendicular to the strip 2 and a gripping flange 5b extending substantially parallel to the strip 2. The strip 2 with the gripping formations 5 are integrally formed and together form a generally C-shaped profile in cross section, as is clearly visible in Fig. 2. In use, the gripping formations 5 grip around the lateral edges of the pipe clip body, such that 35 the gripping flanges 5b extend on the outer surface of the pipe clip body, which in use faces away from the pipe.
-4-
It is also possible to have different gripping formations 5. For example the gripping formation may have only a leg 5a, but no leg 5b.
On the pipe facing side 4 the elongate strip 2 has a plurality of longitudinal ribs 6, 7.
In the longitudinal ribs 6, 7 indents 8 are provided at regular distances in longitudinal 5 direction, whereby a serrated rib 6, 7 is formed as is clearly visible in Fig. 1 and Fig. 3. The serrated ribs 6, 7 comprise consecutive teeth 9, 10 and indents 8.
In the specific embodiment shown in the Figs 1 - 3, the indents 8 are formed as rills extending through the ribs 6, 7 in transverse direction. As a consequence the indents 8 in the parallel longitudinal ribs 6, 7 are aligned, seen in transverse direction of the strip 2.
10 However, it must be noted that it is also possible to provide a staggered configuration of indents.
In the embodiment shown the indents 8 extend all the way to the base strip 2 as is best illustrated in Fig. 3. However, it is also possible that the indents 8 are extending less deep into the ribs 6, 7.
15 In a longitudinal section the teeth 9, 10 preferably have a trapezoidal shape as is best illustrated by Fig. 3. It must be noted that the the flanks of the teeth may have other shapes as well, e.g. curved. However, in view of the production method, which will be described in the following, it is advantageous that mutually facing flanks of consecutive teeth diverge towards the base strip 2.
20 In Fig. 5 and Fig. 6 alternative embodiments of a vibration-isolating insert 51 and 61 respectively are shown. The vibration-isolating insert 51,61 comprises an elongate strip 52, 62 having a pipe clip facing side 53, 63 and a pipe facing side 54, 64. In use the pipe facing side 54, 64 faces the pipe arranged in the pipe clip, and the pipe clip facing side 53, 63 bears against the pipe clip body.
25 Extending from the lateral edges of the strip 52, 62 there extend gripping formations 55, 65. The gripping formations 55, 65 have in cross section generally an L-shape with one leg 55a, 65a extending substantially perpendicular to the strip 52, 62 and a gripping flange 55b, 65b extending substantially parallel to the strip 52, 62. The strip 52, 62 with the gripping formations 55, 65 are integrally formed and together form a generally C-shaped profile in 30 cross section, as is clearly visible in Fig. 5 and 6. In use, the gripping formations 55, 65 grip around the lateral edges of the pipe clip body, such that the gripping flanges 55b, 65b extend on the outer surface of the pipe clip body, which in use faces away from the pipe.
In the specific embodiment shown in Fig. 5, transversal indents 58 are formed in the surface of pipe facing side 54 of the strip. Thereby pipe facing side has transverse ribs 57 35 formed on it, which extend in a transverse direction of the strip, in particular the ribs extend under a right angle with respect to the longitudinal axis of the strip.
-5-
In the specific embodiment shown in Fig. 6, transversal indents 68 are formed in the surface of pipe facing side 64 of the strip. The indents 68 extend slantingly with respect to the longitudinal axis of the strip. Thereby pipe facing side has slanting transverse ribs 67 formed on it, which extend in a transverse direction of the strip. In particular the ribs extend 5 under an angle of about 45° with respect to the longitudinal axis of the strip, but the angle may be in the range of 20° - 90°.
On the pipe clip facing side 3, 53, 63 longitudinal rills may be provided, which is best seen in Figs 1 and 2, where small longitudinal rills are shown. However, it is also possible to provide a flat surface. Furthermore it is possible to provide transversal rills on the pipe clip 10 facing side 3, 53, 63, either at right angles to the longitudinal axis or slanting with respect to said longitudinal axis.
Although not preferred at this time it is conceivable to have a a vibration-isolating insert for a pipe clip, wherein the pipe facing side is substantially flat and the pipe clip facing side is provided with transverse rills either at right angles or slanting with respect to the 15 longitudinal axis of the strip.
In Fig. 4 a method for manufacturing a vibration-isolating insert according to the invention is illustrated. An elongated strip 2‘ of vibration-isolating material, in particular an elastomer, e.g. rubber, is extruded by means of an extruder 20. An elastomer is heated and progresses towards an extrusion head 21 by rotation of a conveyor screw 22. The profile is 20 formed in the extrusion nozzle 23 of the extrusion head 21. The nozzle 23 has a contour corresponding to the cross section shown in Fig. 2. Hence a strip T with longitudinal ribs 6, 7 and with gripping formations 5 is formed through the extrusion head 23.
Downstream of the extrusion head 23 the extruded strip T is pressed with the side where the longitudinal ribs are formed against a rotating gearwheel 24 such that the profile 25 of the gear wheel 24 is pressed in the still warm extruded strip material and forming serrations in the longitudinal ribs 6, 7. The strip T is on the other side, i.e. the side which eventually will become the pipe clip facing side 3, supported by a support block 25.
In the embodiment shown, the gearwheel 24 has teeth which extend over the whole width of the wheel. Thereby the straight transverse rills that are visible in Figs 1 and 3 are 30 formed. It is however also conceivable that the gearwheel has staggered teeth seen in its width direction. By such a configuration, longitudinal ribs 6, 7 can have staggered indents as is also mentioned in the above.
The teeth of the gearwheel 24 have a substantially tapezoidal cross-section, which makes that they are relieved easily from the from the rill that they form as the strip 1 35 progresses. A strict trapezoidal shape is not necessary, but teeth with converging flanks towards their top is preferable.
