Technical Field

The invention relates to a clamping element, in particular a band clamp, a pipe system and a method for producing a pipe system.

Background

Clamp elements, such as band or hose clamps, are known in principle from the prior art. They usually have an annular metal body, the inner diameter of which can be reduced (or also increased) by turning a suitable adjusting device, such as an adjusting screw. This makes it possible, for example, to press the hose lying below onto the connecting piece or to connect two pipes to one another depending on the design of the clamping band element. Such connecting elements are used, for example, in the manufacture of exhaust systems in the manufacture of motor vehicles. In automotive applications and in particular also in the production of exhaust systems, the problem arises that the space conditions are very narrow. It is particularly problematic in this case to provide the clip element pre-assembled in order to achieve a quick installation. This means that the expansion or inner diameter of the annular base body of the clamp element is correspondingly large, so that the clamp element can be placed on the pipe and the hose without prior adjustment. The adjusting device, such as the adjusting screw described above, is therefore of relatively long construction. This results in the adjusting screw projecting in the installed state and requiring construction space which is normally not available or the installed clip element preventing simple arrangement and installation of further components.

Disclosure of Invention

The object of the present invention is therefore to provide a clamping element, a line system and a method for producing a line system, which eliminate the above-mentioned disadvantages and can be implemented in a simple and inexpensive manner.

The object is achieved by a clamp component, in particular a band clamp, according to claim 1, a line system according to claim 9 and a method according to claim 10. Further advantages and features are given by the dependent claims, the description and the figures.

According to the invention, a clamp component, in particular a band or hose band, comprises a first end section and a second end section which are arranged at a distance, in particular at a variable distance, from one another, wherein a first element acts on or rests on or is arranged at the first end section and a second element acts on or rests on or is arranged at the second end section, the elements being joined or engageable with one another by at least one engagement section, and the at least one engagement section being formed (constructed) between the end sections or at least between the end sections. The clip element expediently has a substantially circular or annular base body, which is made, for example, of metal or plastic, which expediently ends in the two end sections mentioned above. The spacing between the end sections can be varied by the cooperation of elements acting on the end sections, whereby the diameter of the base body can ultimately be adjusted. The special feature is that the elements are fitted or engaged in the region between the end sections, which means that the elements, in the mounted state of the band, do not project or project only slightly or do not project beyond the respective end section, depending on the embodiment. In other words, it can be said that the adjustment stroke is shifted into the "pitch". It is therefore advantageous, in particular for at least one of the elements, to form an adjustment stroke in the end section, which means that, for example, a first element can be arranged in a second element and moved in the second element for adjusting the basic body, without the first element having to project or protrude from the second element.

According to a preferred embodiment, the first element is a pin element and the second element is a sleeve element, which extends in the direction of the first end section or into the distance. The sleeve element is expediently supported from the outside on the second end section while extending in the direction of the first end section. Thereby realizing that: the pin element acting on the first end section can be constructed significantly shorter than the pin elements known from the prior art. The sleeve element acts like an "meet" pin element.

Preferably, the pin element is a bolt and the sleeve element is a threaded sleeve cooperating therewith.

According to an alternative embodiment, an intermediate element is provided between the end sections, with which intermediate element the first and second elements cooperate.

Preferably, the intermediate element is a cylindrical threaded sleeve into which the first and second elements, preferably designed as bolts, are screwed. In this embodiment, it can be said that the intermediate element forms a joining section, by means of which the two elements are joined or can be joined to one another.

According to one embodiment, the intermediate element has a functional surface in the circumferential direction for setting tools, so that twisting can be prevented during installation.

In addition to the screw connection, a plug connection or other form-locking and/or force-locking connection can alternatively be provided for realizing the joining section.

According to one embodiment, the joining section extends beyond at least one of said end sections. This means that, for example, the sleeve element can extend not only into the spacing but also away from the spacing in order to provide a still longer adjustment travel for the pin element.

Suitably, the end section has a setting surface on which the element is supported or supportable.

According to one embodiment, the element is movably arranged, in particular rotatable, about an axis extending parallel to the central axis of the strap. This also makes it possible to simplify the adjustment or to improve the force introduction if necessary.

According to one embodiment, a spacer, for example in the form of a sleeve, is arranged between the first element, in particular the pin element (or the second element), and the respective arrangement section.

According to a preferred embodiment, the clamp component is designed as a V-shaped band. For this purpose, in particular, corresponding inner contours are provided on the base body, which are known to the person skilled in the art, so that further explanations are omitted here.

According to one embodiment, at least one of the elements is detachably fixed or arranged on the respective end section. This also increases the flexibility in production if necessary.

The invention also relates to a line system, in particular an exhaust system of a motor vehicle, comprising at least one clip element according to the invention.

The invention also relates to a method for producing a pipeline system, wherein two pipeline sections are connected to one another by means of a clamp element according to the invention. The line section can be, for example, a plastic pipe and/or a metal pipe.

For the line system according to the invention and the method according to the invention, the advantages and features mentioned in connection with the clip element apply analogously and accordingly, and vice versa.

Drawings

Further features and advantages are given by the following description of a preferred embodiment of the clip element with reference to the drawings. The attached drawings are as follows:

FIG. 1 shows a standard clip component in a bolted condition;

FIG. 2 illustrates a partial cross-sectional view of one embodiment of a clip component according to the present invention;

FIG. 3 shows the clip component of FIG. 2 in a bolted condition, broken away and not broken away;

fig. 4 shows a further schematic partial view of an embodiment of a clip element.

Detailed Description

Fig. 1 shows a standard clamp component known from the prior art in the bolted state. The projection U of the bolt S, which can cause problems in the installed or bolted state, can be clearly seen, since the projection U also risks injury and requires unnecessary installation space in particular. The projection U is necessary because the adjustment travel or adjustment distance of the clip element is achieved by the length of the bolt S. The clamp is therefore usually preassembled in the delivered state, i.e. before installation, in such a way that practically no projections U are present, as a result of which the clamp can be installed quickly and simply. Pre-assembly is necessary because otherwise rapid production times in mass production cannot be achieved.

Fig. 2 shows a clamp component 10, which comprises a base body 13, which ends in a first end section 11 and a second end section 12. A first and a second setting surface 24, 25 are formed on the end sections, respectively, on which the first and the second element 21, 22 are supported. The first element 21 is additionally provided with a spacer 30 in the form of a sleeve. In the embodiment shown here, the first element 21 is designed as a pin element, in particular as a bolt, and the second element 22 is designed as a sleeve element, in particular as a threaded sleeve. It can clearly be seen that this design enables the two elements 21 and 22 to be joined in the region of the distance a which is formed between the first end section 11 and the second end section 12. The joining section 40 is therefore formed within the two end sections 11 and 12 and thus in the region of the distance a. In addition, an adjusting path V for the first element 21 is thereby formed in the second element 22. The first element 21 can thus also be screwed more into the second element 22 without protruding or bulging or protruding from the second element 22. In this connection, the adjustment path V can also be considered in particular as an internal adjustment path, which allows the installation space requirement of such a clip element 10 to be minimized. The central axis of the clamp element 10 is also indicated by the reference M. Reference numeral 50 refers to the inner contour formed on the base body 13, since the embodiment shown here relates in particular to a V-shaped band, which is used, for example, in the production or assembly of an exhaust system of a motor vehicle.

Fig. 3 shows the clamp element 10 known from fig. 2 in the bolted state, in a broken-away and non-broken-away manner. In particular, it is also clear from comparison with fig. 1 that the projection U is minimal or may not be present at all depending on the distance of the screw connection. Nevertheless, a maximum adjustment distance or a very large opening diameter can be achieved in the pre-installed state as shown in fig. 2, as in conventional clip elements. Reference is made to figure 2 with regard to other features provided with reference numerals.

Fig. 4 shows a diagrammatic view of a clamping element 10, which comprises a base body 13, which ends in a first end section 11 and a second end section 12. The joining section 40 is realized here by an intermediate element 23 into which the first element 21 and the second element 22 are joined. The first element 21 and the second element 22 are configured as bolts, for example, while the intermediate element 23 is a threaded sleeve.
