Definitions

  • the invention relates to a pipe clip for fastening a pipe to a wall, ceiling or another support.
  • the pipe clip comprises a clip body with an opening for attaching the pipe clip around the pipe, which opening is delimited by a first and a second end of the clip body.
  • the pipe clip furthermore comprises a tightening element comprising a head and a shank, the head of which tightening element engages with the first end of the clip body.
  • the pipe clip also comprises a female fastening element which is pivotably connected to the second end of the clip body and wherein the shank of the tightening element is inserted.
  • This type of pipe clip is known, for example from EP 1 431 641 A2 and DE 34 39 418.
  • the known pipe clips have a clip body with an opening for attaching the pipe clip around the pipe, which opening is delimited by a first and a second end of the clip body.
  • An integrally formed first and second flange are respectively located at the first end and at the second end respectively of the clip body.
  • the second flange has an elongate hole.
  • a nut is attached to the side of the second flange that is facing away from the first end so as to be able to pivot in relation to the clip body.
  • the shank of a tightening screw is inserted into the nut.
  • the first flange is provided with an elongate recess which is open on the side of the flange that is facing away from the clip body.
  • the play required to move the head of the tightening screw along the edge of the first flange is obtained as a result of the fact that the nut is pivotably fastened to the clip body.
  • the tightening screw can pivot sideways and move along the edge of the flange.
  • the shank of the tightening screw is received in the open recess of the first flange.
  • the nut used is a spring nut, allowing the shank of the tightening screw to be pressed deeper through the clip during closing thereof.
  • the nut used is a plate with a hole which is provided with a screw thread and into which the tightening screw can be screwed.
  • DE 40 15 404 discloses a different type of pipe clip, wherein the pipe clip has at one end a flange which is provided with a bore provided with a screw thread. The screw thread is screwed into this bore and is fixed in relation to the flange.
  • the pipe clip has at the other end a flange with a recess which is open on the side facing away from the clip body.
  • the recess in the flange has a width which is greater than the diameter of the head of the tightening screw.
  • Pivotably attached to the side of the flange that is facing away from the other flange is a arresting mechanism which has a recess that is open on the side facing away from the clip body.
  • This recess has a width smaller than the diameter of the tightening screw.
  • the invention has for an object to provide an improved pipe clip.
  • a pipe clip comprising a clip body with an opening for attaching the pipe clip around the pipe, which opening is delimited by a first and a second end of the clip body.
  • the pipe clip furthermore comprises a tightening element comprising a head and a shank, the head of which tightening element engages with the first end of the clip body.
  • the pipe clip also comprises a female fastening element which is pivotably connected to the second end of the clip body and wherein the shank of the tightening element is inserted.
  • the first end of the clip body comprises a first flange with a recess for the shank of the tightening element, which recess has dimensions such that the head of the tightening element fits therethrough.
  • An arresting plate is pivotably attached to the side of the first flange that is remote from the second end of the clip body, which arresting plate has a recess which is open on one side for the shank of the tightening element, so that when the head of the tightening element is pressed through the recess in the first flange against the arresting plate during closing of the clip body, the arresting plate is pivoted in such a way that the shank of the tightening element is received in the recess of the arresting plate via the open end.
  • the pipe clip according to the invention allows a tightening element having a shorter shank to be used while still providing the play required in order easily to be able to close the clip. Subsequently, the tightening element can be screwed or optionally pressed further into the female fastening element, which preferably comprises a nut, in order effectively to tighten the clip around the pipe. As a result of the fact that a shorter shank can be used, the tightening element also has to be tightened or pressed to a lesser degree in order to tighten the ends of the clip relative to one another, and this greatly reduces the fitting time.
  • the recess in the first flange is formed as a hole through which the head of the tightening element fits, preferably a hole with a wide portion through which the head of the tightening element fits and a narrower portion in which the shank of the tightening element can at least partially be received to allow a pivoting movement of the shank of the tightening element.
  • the hole in the flange ensures that once the head of the tightening element is moved along the edge of the arresting plate, it cannot become detached again once the shank of the tightening element is received in the recess of the arresting plate.
  • FIG. 1 is a perspective view of a pipe clip according to the invention during closing of the clip
  • FIG. 2 is a perspective view of the pipe clip from FIG. 1 after closing of the clip but before tightening of the tightening screws;
  • FIG. 3 is a perspective view of the pipe clip from FIG. 1 with exploded parts.
  • FIGS. 1-3 show a pipe clip 1 with a metal clip body 2 comprising two metal clip halves 3 and 4 respectively.
  • the clip halves 3 and 4 are provided at one end with flanges 5 and 6 respectively.
  • the flange 6 is provided with a hole 7 which is provided with a screw thread and into which a tightening screw 9 can be screwed.
  • the flange 5 is provided with an elongate hole 8 through which the shank of the tightening screw 9 can be inserted.
  • the elongate shape of the hole 8 allows the clip half 3 to be moved in a hinging manner in relation to the other clip half 4 around a hinge axis which is substantially parallel to the axial direction of the clip 1 , when the tightening screw 9 has not been fully tightened.
  • the hole 8 could also be shaped differently, provided that a hinging movement between the clip halves is possible.
  • the clip halves 3 , 4 could also be connected by means of other hinging means.
  • the clip body 2 has a first end 11 and a second end 12 which delimit an opening 13 for attaching the pipe clip 1 around a conduit.
  • the size of the opening 13 can be increased and decreased respectively by hinging the clip halves 3 and 4 apart from each other and hinging them toward each other respectively.
  • Reference numeral 30 denotes the location at which a nut or the like is attached to the outside of the clip half 4 . This nut, which cannot be seen in the drawing, allows the pipe clip to be suspended from a threaded end.
  • FIGS. 1 and 2 show how a vibration-damping lining 14 is attached to the inside of the clip body 2 .
  • This lining 14 is preferably made of an elastomer, for example rubber, or another resilient material and has a substantially C-shaped cross section. The lining 14 engages with the flanges of the C shape around the clip halves 3 and 4 of the metal clip body 2 .
  • a first flange 15 is formed integrally at the first end 11 and a second flange 16 is formed integrally at the second end 12 .
  • the pipe clip For closing the pipe clip 1 and keeping it closed, the pipe clip comprises a tightening element, in particular a tightening screw 18 such as is shown in FIGS. 1 and 2 .
  • the tightening screw 18 has a head 19 and a shank 20 which in the example shown is provided over its entire length with an external screw thread.
  • the shank 20 could also be provided over a portion of its length with a screw thread profile or the like.
  • a nut 21 is attached to the second end 12 , on the side of the second flange 16 that is facing away from the first flange 15 , in order to cooperate with the tightening element 18 to keep the pipe clip 1 closed.
  • the nut 21 has a pivot arm 22 which is clipped between the clip half 4 and the vibration-damping lining 14 . This allows the nut 21 to perform a pivoting movement in relation to the second flange 16 , such as is illustrated in FIG. 1 and FIG. 2 .
  • FIG. 1 shows the pivoted position of the nut 21 with the tightening screw 18 inserted therein.
  • FIG. 2 shows the rest position of the nut 21 and the tightening screw 18 inserted therein.
  • the upper side of the nut 21 preferably rests against the underside of the second flange 16 .
  • the resilience of the material of the vibration-damping lining 14 ensures that the nut 21 is moved with the tightening screw 18 when unloaded toward the rest position of FIG. 2 .
  • Shown as a member for fastening the nut to the clip body 2 is in this case a pivot arm 22 which is slid between the metal clip body 2 and the lining 14 .
  • a fastening member which is inserted through an opening, formed for this purpose in proximity to the second flange 16 , in the clip body and which is positioned partially between the lining 14 and the clip body 2 in order to obtain a resilient hinging effect.
  • a construction of this type is disclosed, for example, in EP 1 431 641 A2. It should be noted that constructions which derive their resilience not from the flexible lining 14 but rather from other spring means are also conceivable within the scope of the present invention.
  • the nut 21 used may be a spring nut, wherein the shank 20 of the tightening element 18 can be pressed, instead of screwing, further into the spring nut during closing of the pipe clip 1 .
  • a spring nut of this type is known, for example, from EP 1 431 641 A2, wherein the spring nut consists of a plastics material part and a metal part.
  • Other spring nuts which can be used in the pipe clip according to the invention are, however, also conceivable.
  • the nut 21 used is a nut body with a hole provided with a screw thread such as is shown, for example, in DE 34 39 418.
  • the pipe clip 1 is clipped tight by screwing the tightening screw 18 further into the nut.
  • a narrower portion 25 attached adjoining the round portion 24 of the hole 23 is a narrower portion 25 which, when the tightening screw 18 pivots out, can receive the shank 20 of the tightening screw 18 , such as is represented in FIG. 1 .
  • the hole 23 could also be completely round or, for example, elongate. All that matters is that the head 19 of the tightening element can be inserted through the hole 23 .
  • An arresting plate 26 is attached to the side of the first flange 15 that is facing away from the second flange 16 .
  • the arresting plate 26 is provided with an elongate recess 28 which is open on the side facing away from the clip body 2 .
  • the recess 28 has a width which is smaller than the diameter of the head 19 of the tightening screw 18 but which is larger that the diameter of the shank 20 of the tightening screw 18 .
  • the arresting plate 26 has a pivot arm 27 which is clipped between the metal clip half 3 and the rubber lining 14 . This allows the arresting plate 26 to perform a pivoting movement in relation to the first flange 15 , such as is illustrated in FIG. 1 and FIG. 2 .
  • a different member for fastening the arresting plate 26 could also be provided in order to fasten the arresting plate 26 to the pipe clip 1 .
  • a fastening member such as that shown for the spring nut from EP 1 431 641 A2 also for the arresting plate 26 , the fastening member being inserted through an opening, formed for this purpose in proximity to the first flange 15 , in the clip body 2 and positioned partially between the lining 14 and the clip body 2 in order to obtain a resilient hinging effect.
  • constructions which derive their spring effect not from the flexible lining 14 but rather from other spring means are conceivable within the scope of the present invention.
  • FIG. 1 shows the pivoted position of the arresting plate 26 , the head 19 of the tightening screw 18 being pressed against the side of the arresting plate 26 that faces the first flange 15 .
  • FIG. 2 shows the rest position of the arresting plate 26 , the head 19 of the tightening screw 18 being positioned above the arresting plate 26 and the shank 20 of the tightening screw 18 being received in the open recess 28 .
  • the underside of the arresting plate 26 rests in this case against the upper side of the first flange 15 .
  • the resilience of the material of the lining 14 ensures, just as in the case of the nut 21 , that the arresting plate 26 is moved toward the rest position of FIG. 2 when unloaded.
  • the pipe clip 1 operates as follows: The pipe clip 1 is hinged open about a hinge axis which is defined by the hinge construction diametrically opposing the opening 13 and extends in the axial direction. As a result, the opening 13 between the ends 11 and 12 of the clip body 2 is enlarged, so that the pipe clip 1 can be attached around a pipe. Subsequently, the clip ends 11 and 12 are moved toward each other in order to close the clip 1 . In this case, the head 19 of the tightening screw 18 is inserted through the wide portion 24 of the hole 23 in the first flange 15 and the head 19 of the tightening screw 18 is pressed against the side of the arresting plate 26 that faces the first flange 15 .
  • the arresting plate 26 is pivoted toward a position wherein the arresting plate 26 is positioned obliquely in relation to the flange 15 and the free end of the arresting plate 26 is moved upward (see FIG. 1 ).
  • the tightening screw 18 the shank 20 of which is inserted into the pivotable nut 21 , is moved toward an oblique position shown in FIG. 1 . Pressing the clip ends 11 and 12 further toward each other will cause the head 19 of the tightening screw 18 to be guided along the obliquely positioned face of the arresting plate 26 toward the edge of the arresting plate 26 that opposes the pivot arm 27 until this edge has been passed.
  • the cooperation of the pivot arm 27 with the resilience of the lining 14 will cause the arresting plate 26 to recoil in the direction of the rest position (see FIG. 2 ) and the tightening screw 18 is also recoiled toward a rest position (see FIG. 2 ) as a result of the cooperation of the pivot arm 22 with the lining 14 .
  • the shank 20 of the tightening screw 18 is brought into the recess 28 of the arresting plate 26 .
  • the clip 1 can be further tightened by tightening the tightening screw 18 and possibly also 9 further, wherein the underside of the head 19 comes to rest on the side of the arresting plate 26 that is facing away from the first flange 15 .
  • the two clip ends 11 and 12 are thus provided with a pivotable component.
  • This is in contrast to pipe clips known in the art wherein merely one of the clip ends is provided with a pivotable component.
  • the invention allows the clip easily to be closed using the quick-acting closure with the tightening screw having a shorter shank than is the case in the known solutions.
  • a shorter shank provides a more attractive appearance, certainly in the case of pipe clips for pipes having small diameters.
  • the short shank is advantageous above all because once the clip 1 has been closed using the quick-acting closure, the fitter has to tighten the tightening screw 18 merely over a short shank, thus reducing the fitting time.
