Plastic holder for at least one pair of pipes

The innovation relates to a plastic holder for at least one pair of pipelines, in particular fuel, brake fluid or similar lines in motor vehicles, with a sock-shaped fastening part to which the pipelines overlapping retaining arms are fastened are.

A plastic holder of the above type that allows a pair of pipes to be fastened at the same time by simply Clipping in of the pipelines is possible, for example, through the German utility model G 81 20 413.2. the However, holding arms for the two pipes are on here arranged opposite sides of the sock-shaped fastening part, so that the two pipes mounted 1m State have a relatively large mutual distance. In addition, the holding and withdrawal forces are here due to the resilient mounting of the pipelines in the holding poor relatively limited.

The innovation is based on the object ₄ to create a plastic holder for simultaneous pairs, simple mounting of pipelines, which allows a very close arrangement of the pipework. In addition, the plastic holder is intended to achieve significantly greater holding and pull-off forces compared to the prior art.

According to the innovation, this object is achieved in a plastic holder of the type indicated in that

a) a footplate is formed on at least one side of the sock-shaped fastening part, of the two mutually spaced by a narrow gap holding arms substantially extend upwards parallel to the fastening part,

b) a locking tongue 1m on the upper edge of the first holding arm adjacent to the fastening part acute angle is articulated 1st, which extends against a receiving space for a pipeline and this is tangent with its inner edge and a V-shaped with the adjacent fastening part The entry gap for this pipeline is limited,

c) the second holding arm has an outwardly directed, essentially sickle-shaped cross section and with an outer, arched retaining tab, a further receiving space for a pipeline limited and

d) the second holding arm has a wedge-shaped upwardly extending projection, which with the outer retaining tab delimits a V-shaped insertion gap for the second pipeline.

• * I t

In the conventional way on a supporting base Attached plastic holder according to the innovation can be advantageous a pair of pipelines are clipped in close proximity at the same time, which is e.g. may be desirable for manufacturing reasons. Due to the special training and Arrangement of the retaining arms as well as the outer retaining strap these parts sufficiently laterally to the outside, i.e. from the fastening * part of the holder away, bend elastically to prevent the pipelines from snapping into the receiving spaces at the same time between the first holding arm and the base-like fastening part or to enable the second retaining arm and the outer retaining tab. After the pipelines have been installed the plastic holder guarantees sufficient! great holding and pulling forces. This is due to

j lead that the locking tongue of the first holding arm

ι automatically attaches itself to the base when pulling forces

! shaped fastening part locked and on the other hand the

ι the second holding arm the assigned pipeline with his

\ sickle-shaped cross-section overlaps a considerable amount.

If, according to an embodiment, the innovation differs from the Asymmetrically arranged grooves with a rounded base extend into the base plate for receiving spaces for the pipelines, the lateral spring deflection of the retaining arms and the outer retaining bracket when the pipelines are clipped into favors the holder.

If, according to yet another embodiment of the innovation, the first holding arm opposite the locking tongue with a recess is provided to at least a part when a pipe is pressed into the EinfUhrungsspalt the locking tongue, the assembly of this pipeline is further facilitated.

• It (

Securing one pipe in the assembled Z-stand against unintentional loosening is much better if the base-shaped fastening part has a stop for has the free end of the locking tongue.

Clipping in two pipes in pairs at the same time 1n the holder is further facilitated if, according to yet another embodiment of the innovation, the base-shaped fastening part, the first and second holding arm and the outer painting tab have the same height.

By means of yet another embodiment of the innovation accordingly the protection claim 6 can simultaneously two pairs of pipes, each closely adjacent, on one load-bearing base.

The innovation is then explained using the drawing of an exemplary embodiment. Show it:

Fig. 1 is a side view of a plastic holder according to the innovation for two Ro!: rleitungs-pairs, one of which in the assembled state and the other is indicated before assembly and

FIG. 2 is a plan view of the holder of FIG. 1.

The plastic holder shown in the figures as an exemplary embodiment 13 is used to fix two pairs of pipes 10, 11 or 10 A, 11 A on a supporting base 12, which can be, for example, a body part of a motor vehicle. The pipelines can be, for example Act on fuel and brake fluid lines.

The plastic holder 13 has a central sock-shaped fastening part 14 which has a cavity contains known anchoring means which claw on a threaded bolt 15 when the plastic holder 13 is attached to this. The threaded bolt 15 is attached to the supporting base 12, e.g. welded on.

The fastening part 14 extends on both sides a footplate 16 formed thereon. From this footplate 16, holding arms 17, 17 A and 18, 18 A extend and two outer arcuate retaining tabs 19, 19 A upwards. All retaining arms and the outer retaining tabs In the exemplary embodiment, they have the same overall height, which corresponds to that of the sock-shaped fastening part 14.

The holding arms 17, 17 A adjacent to the central fastening part 14 each contribute one at an acute angle 20 articulated locking tongue 21, the reinforced inner edge of which a receiving space 22 and 22 A for the pipeline 11 or 11 A is tangent. On the sock-shaped fastening part 14 are laterally stops 23 and 23 A for the locking tongues 21, 21 A molded. If e.g. 11 A pull-off forces act on the installed pipeline, the locking tongue 21 A lies against the stop 23 A, making this pipeline absolutely safe is held.

To clip the pipeline 11 or 11 A into the Plastic holders 13 to facilitate are between the Locking tongues 21 and 21 A and the adjacent fastening point 14 V-shaped entry gaps 24, 24 A intended for the pipelines mentioned. When clipping in the pipes 11 or 11 A 1n the plastic holder 13, the locking tongues 21 and 21 A bend against
