Abstract

THE INVENTION RELATES TO A FIXING ELEMENT FOR AT LEAST ONE PIPING, IN PARTICULAR A GASOLINE, ON A MOTOR VEHICLE. THIS FASTENING ELEMENT INCLUDES A MOUNTING PART 1 AND AT LEAST ONE BINDING PART 2 PARTIALLY SURROUNDING THE PIPING. THIS BINDING PART 2 IS CONSISTING OF THREE SHELL-SHAPED ELEMENTS: A CENTRAL SHELL 8, AN INTERNAL SHELL 3 AND AN EXTERNAL SHELL 4. THANKS TO THE CENTRAL SHELL 8 AND THE INTERNAL SHELL 3, IT IS POSSIBLE TO MOUNT IN A SAFE MANNER , WITH A SINGLE FIXING ELEMENT, PIPES OF DIFFERENT DIAMETERS WHILE PROTECTING THEM FROM STONE PROJECTIONS.

Description

A fastener for at least one

  pipeline, in particular a pipeline

  gasoline, on a motor vehicle This fixing element

  tion includes a mounting part and at least a fixed part

  xation which partially surrounds the pipeline and which is

  consisting of two shell-shaped elements, a co-.

  inner keel and an outer shell surrounding the

  first at a certain distance These two shells present

  try a penetration area for the pipe to be assembled,

  with an outer shell lip and an ex-

  of the mounting part which form between them a

  gap leading to the inner shell.

  The state of the art includes an element of

  xation of this kind, already known, which is used to fix cana-

  Readings (German patent 30 02 031) Due to the dis-

  Axial tance between the inner shell and the outer shell, the inner shell can, with this model

  known, receive pipes of different diameters.

  The state of the art further includes an element

  fixing which is made in such a way that the

  shell-shaped mounting is surrounded by a shell-

  the additional having the form of a U-shaped sheet envelope, fixed to the fixing element (English patent 1,403,714) The disadvantage is that the pipe is not

not securely attached.

  There is also known an anchoring device with which a fixing system has come from molding on a head (German patent application 28 16 181) There are two C-sections, the concavity of the first section being turned towards the another section facing it A tube

  can be placed between the two sections.

  reading of this known construction is also limited

  with regard to the installation of pipelines of different

annents diameters.

  The object of the present invention, on the other hand, is to create, starting from the state of the art mentioned above, a fixing element which can also receive, in a simple manner, pipes of very different diameters. This object is achieved, according to the invention, because the fixing part has, inside, a resilient central shell located at a certain distance from the inner shell, which surrounds it.

  allows, first of all, to fix on its own a pipe-

  Smaller diameter If larger diameter pipes are used, the central shell is deformed and,

  with the inner shell, it maintains the channel-

  tion This makes it possible to fix pipes perfectly

of very different diameters.

  According to another feature of the invention, the

  central shell begins in the surface area ex-

  of the mounting part and ends inside the perimeter of the central shell, so that, for large diameter pipes, a good combined action of the internal shell and the central shell is obtained. The central shell can cover a sector

around 1800.

  According to another feature of the invention, in the case of a fastening element whose inner shell has, in the recess area, a spout directed towards the

  inner perimeter of the outer shell, zone a-

  front of the central shell may have a finite part

  smooth nale This allows the central shell to apply

  more or less against the inside perimeter of the co-

  inner keel and maintain, with this, a pipe

of large diameter.

  With another embodiment of the invention,

  the inner shell may have a groove which extends

  tends over the entire perimeter and in which the shell

  central unit can be housed, at least in part Thanks to this-

  te possibility of housing the central shell in the inner shell, it is even better able to

  produce its effect for large diameter pipes

  and it holds these pipes perfectly The shell cen-

  trale can go to about the same height as the

inner shell.

  It is also possible that the central shell has at its lower part longitudinal guides covering the length of the groove that has the inner shell These guides serve to guide and support as long as possible the pipe in the fixing element The guides can be thin-walled and release the lower part of the central shell

  in addition, the groove can extend to the outer shell.

  Other features and advantages of the invention

  will appear in the description which follows, made in re-

  reference to the appended drawing, which represents exemplary embodiments thereof.

  Fig 1 is a schematic elevation of an element

fixing.

  Fig 2 shows another embodiment

  of a fixing element, with partial tearing off.

  Fig 3 is a bottom view of another mode

  of the fixing element.

  Fig 4 is the elevation of the fixing element

  tion of Figure 3, with partial cutaway.

  The fixing element represented in FIG. 1 consists essentially of a mounting part 1 and

  a fixing part 2 This fixing part 2 is intended for

  born to receive a pipeline, in particular a canali-

  petrol station on a motor vehicle The fuel part

  xation 2 partially surrounds the pipeline and thus

maintains it perfectly.

  This fixing part 2 consists of two

  shell-shaped elements, namely an interior shell

  3 and an outer shell 4 which surrounds the preceding

2546? 61

  tooth at a certain distance The inner shell 3 and the outer shell 4 have a recess area

  common 5 intended for the pipeline to be mounted.

  In addition, the outer shell 4 has a lip 6 and the mounting part 1 has an outer surface 7. The lip 6 and the outer surface 7 ensure a good introduction of the pipe to be held. The fixing part 2 has, inside, a elastic central shell

  8 located at a certain distance from the inner shell

  upper 3, which surrounds it The central shell 8 begins

  in the area of the outer surface 7 of the mon-

  stage 1 and it ends inside the perimeter of the inner shell 3 For the embodiment of FIG. 1, the central shell 8 extends over approximately 1800

  and it ends in the front part 9.

  If a small diameter pipeline is main-

  held in the fixing part 2, the central shell 8

  works in combination with the inner shell 3 and main-

holds the hose.

  In the case of a large diameter pipe, the co-

  central keel 8, which is elastic, is pushed back,

  so that the insert space 13 between the shell-

  the central 8 and the inner shell 3 decreases; the co-

  elastic central keel 8 and the elastic inner shell-

  tick 3 also maintain this channel perfectly.

  In the extreme case, the intermediate space 13 between the central shell 8 and the inner shell 3 can be reduced to zero, which makes it possible to maintain perfectly

large diameter pipes.

  In the case of the embodiment of FIG. 2, the inner shell 3 has a groove 10 Here again,

  there is an intermediate space 13 between the inner shell

  re 3 and the central shell 8 The inner shell 3 frames the central shell 8 like a fork Si

  the fixing part 2 of the fixing element of the invention

  tion maintains a large diameter pipe, this large diameter pipe pushes the central shell 8 in the groove 10 of the inner shell 3, that is to say that the central shell 8 rests in the inner shell * shaped fork 3 With this known embodiment, the inner shell 3 has a lip 14 which is roughly

  parallel to a lip 15 of the central shell 8 We obtain

  thus holds, in combination with the outer surface 7, the lip 6 and the lips 14 and 15, during the introduction of a pipe which must be fixed, a very good positioning thereof until what it is surrounded by the shell

  central 8 and by the inner shell 3.

  With the embodiment of Figures 3 and

  4, there is again a groove 10, so that the co-

  inner keel 3 frames the central shell 8 at the

  like a fork This groove 10 extends to the shell

  the outer 4, so that a notch 16-is formed in the outer shell 16 On this model, the part

  bottom of the central shell 8 has guides

  longitudinal ges 11 As shown in Figure 3, these longitudinal guides It extend on both sides of the central shell 8 and, at its lower part 12, they

  let this central shell 8 end freely.

  Thus, when it receives a pipe of large diameter-

  tre, this central shell 8 can also penetrate, up to

  that at its lower part 12, in the groove 10 of the co-

  inner keel 3 in the shape of a fork, and it can therefore hold the large diameter pipe well The pipe

  is well guided, on both sides, by the guides 11.

  As shown in Figure 4, the radius of the inner shell 3 is offset from the radius of

  the central shell 8 The centers of the central shell

  trale 8 and the inner shell 3 are therefore offset

  one with respect to the other by a distance e.

  The invention makes it possible to perfectly maintain pipes of different diameters by means of a single fixing element, by virtue of the central shell 8 and the interior shell 3, said diameters possibly being comprised, for example, between 5 and 10 mm. thus obtains a reduction of stocks, the pipes being however well maintained and, moreover, protected from projections of stones by the external shell 4 The insertion zone 5 gives

  quick assembly and also allows disassembly

easy.
