Clip made of plastic for the detachable fastening of a pipeline

The present innovation relates to a clip made of plastic for detachable Fastening a pipe to a wall, ceiling or the like solid base.

There are already clips and clip-like devices made of plastic known, with which pipes or cables can be releasably attached to a wall, ceiling or the like solid base. Underneath there are also integral clip-type devices. A known device of this type, from which the present innovation is based, consists of an essentially U-shaped console piece, whose The web is to be attached to the base with a screw or nail. The two bracket legs each end in a thin, flexible section. At each of these flexible bracket leg ends a bracket is arranged so that the two bracket against each other are movable and together result in a clamp spanning the pipe to be fastened. The bracket is divided by two in the vertex each located on a clamp leg end directed against each other Hook closed.

Such brackets are very useful for several reasons: They each consist of only one workpiece that is easily attached to the support is to be attached. The pipes to be installed can be fastened in the clamps in a few simple steps. The fastening of the line pipes can be easily removed again, so that damaged pipe sections can be replaced quickly.

The well-known brackets, from which the innovation is based, have also a significant flaw: Even with relatively minor vibrations the clip lock can open. This has a very disadvantageous effect, especially in pneumatic tube systems, since this is in Eogen areas quite considerable vibrations cannot be avoided.

The innovation is therefore based on the task of a Klamrrrer in particular to create for the attachment of pneumatic tube pipes, although one j

side has the advantages of known brackets, which, however, are not associated with de- i

ren disadvantages. The brackets should also to a certain extent measure to dampen vibrations of the line pipes.

To solve this problem, the innovation is based on a one-piece Clip made of plastic for detachable fastening of a pipeline a wall, ceiling or the like solid base that consists of a consists essentially of a U-shaped console piece, the web of which on the base is to be fastened by a screw or a nail and des- ' sen bracket legs each in a thin, flexible, parallel to the pipeline extending connecting web ends, at the free end of a circular segment-shaped clip bracket is arranged so that the connection: attachment web engages below the middle of the bracket and that both clamp brackets,

together form a bracket surrounding the pipe, which is indicated by an |

hooks facing each other on the temple ends closed \

The problem posed is achieved according to the invention in that the A stop lug is arranged each at the lower ends of the clamp bracket and / or that there are abutments on the inside of the bracket piece, whereupon the lower ends of the clamp brackets are supported in the closed position of the clamp.

A preferred embodiment is that the lower ends the bracket are angled against the console piece and thus Form stop lugs with which the clamp brackets are supported in the closed position on the web of the bracket piece.

The innovation is shown below using an example that reproduces it Drawing explained in more detail. The drawing shows a view of the bracket according to the innovation in the direction of the pipe axis.

The clip according to this embodiment is a one-piece injection molded part made of thermoplastic material. It consists of a substantially U-shaped bracket piece 1, the web la on a Wall is fixed by means of a screw 2 and its bracket leg Ib, Ic each in a thin, flexible, parallel to the pipe axis End connecting web 3a, 3b. At the free end of the connecting webs 3a, 3b there is in each case a circular section-shaped clip bracket 4a, 4b arranged so that the connecting webs 3a, 3b engage below the middle of the bracket. The two clip brackets 4a, 4b together form one Clamp that engages around the pipe 5 to be held.

The inner ends of the clamp brackets 4a, 4b are towards the console piece 1 angled and thus form stop lugs 6a, 6b with which the bracket ends are supported on the web la of the bracket piece 1 in the closed position.

The outer ends of the clip brackets 4a, 4b are as opposed to one another Hooks 7a, 7b formed, which together form a closure located in the apex of the clamp.

At a short distance from the hooks 7a, 7b are on the outside the clamp bracket 4a, 4b arranged radially protruding tabs 8a, 8b. This means that you can still use the pliers to open the clamp close when the clamp is very tight on the pipe to be held and the force of the bare hands to close the clamp is no longer available sufficient.

The tab 8a assigned to the inner hook 7a can also be used as an abutment for a flat tool, e.g. a screwdriver, with the help of which you can open the clamp by levering out the outer hook 7b

can open easily.

In order to give the clamp brackets 4a, 4b a certain flexural rigidity, they are each provided with a stiffening rib 9a, 9b on their outside.

The assembly of pipelines with the help of the brackets according to the innovation is very simple: you attach the clamps to the surface, bend them Spread the clamp legs apart, insert the pipeline and close the clamps again.

Replacing a damaged pipe section is very easy possible that one opens the clamps, as already said, with the help of a screwdriver or similar tool. This can be done without any damage to the clip occurs, so that after insertion of a new pipe section the clamp can be closed again intact.

The application of the concept of innovation is not to what is described here Embodiment limited. For example, the abutments for the inner ends of the bracket stirrups can also consist in that Stop lugs are arranged on the inside of the console piece. A combination of the two possibilities is also conceivable in such a way that the lower ends of the clip brackets are angled towards the console piece and that abutments are provided on the console piece, on which the angled ends of the bracket brackets are supported or even snap into place. The support of the inner clamp ends is very essential for a reliable function of the clamps according to the innovation. This prevents that the closure of the clamp opens when the pipeline is shaken.
