Dialing device

The present invention relates to a marking device for at least one line.

In installations with electrical, fluid or light conduits, it is necessary, in general, that the conduits - in particular the cables - be marked for the purpose of the association. To this end, figures and / or numbers and / or symbols are stably applied on the outer side on label plates, which, however, can be printed on a label, which is then glued on the label plate. The articulated joint of the two partial shells can be done with a hinge and the two partial shells can be locked together by means of a retention hook, which forms the end zone of a partial shell and can be inserted for mooring in a retention housing of the other partial shell. In this position, a step-shaped retainer engages behind the retainer housing.

According to the state of the art of the type indicated at the beginning according to EP 0 924 712 B1, the compensation element is configured as a loop-shaped clamp. In this embodiment, which has been successful in itself, the ducts of the smallest diameter area rest outside the center in the partial shell of the labeling plate, which can be considered as an angular shape in the cross-section. The grip of this marking device must be further improved.

In addition, the document US 5,115,586 is referred to in the prior art. In this publication, in a marking device formed in the same way by two half shells locked together, by virtue of the selected geometry of the compensation device it is only possible with difficulty to mark a conduit, whose inner diameters correspond almost to the inner diameter of the half shells locked together.

Regarding the prior art, documents DE 20 2007 005 663 U1, DE 299 16 770 U1, DE 198 19 865 Al, DE 689 072 11 T2 and DE 20 2004 009 980 U1 are still mentioned.

In US 5,115,586 a marking device is described, which is constituted by two half-shells connected in an articulated manner, which can be tied together in the locked state of the inserted conductor. On the inner side, in the semi-shells there are magazines or ribs of the type of blades, which can either be elastically deformed and, therefore, interlock the conductor or cut into the conductor envelope. In this way, the area of ​​the diameter of the inserted conductor is relatively small.

In GB 2 237 261 A a marking device is described, which is constituted by a plurality of fasteners juxtaposed with each other. These fasteners have a labeling plate stably in themselves, in which the elastically deformable zones are connected, so that the cross section is closed. The fastening is carried out through the deformation of the arms opposite the labeling plate, so that also the area of ​​the diameter is relatively small.

WO 2009/033946 A2, which falls under Art. 54 (3) EPÜ, publishes a marking device with two flat elements, which are joined together with a hinge. One of these flat elements has a flexible deformable element in the center, which adapts through deformation to the size of an electrical conductor.

Given this background, the purpose of the invention is to further optimize the marking device, increasing the area of ​​the diameter of the conduits to be fixed against the embodiments described above. The invention solves this task by means of the object of claim 1. The object of claim 2 can be considered as development of claim 1.

According to claim 1, the partial shell, which has the marking zone, on whose inner side pointing towards the conduit, is configured prismatically at least in the marking zone and the compensation element is configured as a body of elastic support opposite to the area of ​​labeling in the locked state.

By means of the prismatic configuration of the inner surface the duct is centered, that is, it always aligns exactly in the center. This is done in connection with the pressure force applied by the support body on the duct. The inner surface in prismatic form is designed in this case on the maximum diameter of the duct to be marked. The same also applies to the elastic support body, which exerts a pressure force also still in conductor in the lower area of ​​the diameter.

According to the characteristics of claim 2, the elastic support body is arranged and configured in one of the partial shells such that during the marking of conduits from a predetermined diameter of the conduit through an opening in the shell partial is pressed on the outer periphery of this partial shell out. Such parts can also arrive from a certain diameter

of the support body through the "out" opening. In this way, ducts can also be easily marked, the diameter of which corresponds almost to the inside diameter of the closed marking device.

According to a preferred embodiment, it is provided that the support body is configured in the trapezoid or inverted U-shaped cross-section with respect to the moored state of the two partial shells. In this way, extreme deformation is achieved in ducts in the area of ​​the maximum diameter, so that the recovery forces are correspondingly large. However, the support body is also designed in such a way that pressure forces are still applied in ducts in the area of ​​minimum diameter.

So that the deformation of the support body is always constant, according to a preferred configuration it is provided that it is provided with several constrictions of the lateral section arranged at a distance from each other. These can then also be provided alternately on different sides of the support body.

According to another embodiment, the support body is provided to extend in an arc. But the recovery forces applied through deformation are in this embodiment more reduced than in the embodiment mentioned above. So that the deformation of this support body is also conveniently provided, the constriction of the cross-section is in the central area and preferably extends continuously.

So that sufficient pressure forces are still transmitted in the lower area of ​​the diameter from the support bodies, it is provided that with respect to the tension-free state of the support body, the area associated with the labeling plate is projected beyond the plane of separation formed by the partial shells in the direction of the labeling plate. In the tension-free state, then the area of ​​the support body that is associated with the label plate penetrates to the partial shell that the label plate carries.

The prismatic shape of the inner surface of the partial shell bearing the label plate is formed by two inclined surfaces that form an obtuse angle. In this case, the transition zone between the two inclined surfaces extends in an arc.

In addition, it is provided that at least one or both partial shells are configured in a semicircular manner in the cross section. For its mooring, it is provided that the free end zone of the partial shell that has the support body is configured as a retention hook with a retainer and the free end zone of the partial shell that carries the labeling plate is configured as a retention housing .

According to another variant and configuration, the marking devices, in particular their labeling plates, are configured such that several marking devices can be placed directly adjacent to each other axially or in the direction of the conduit, for which purpose the extreme areas placed adjacent to each other of the marking devices, in particular of the marking plates, preferably engage in positive connection and / or by force application.

The marking devices 1 shown in Figures 1 to 19 have two partial shells 2, 3 configured in the cross-section, preferably in a semicircular shape, which are articulated together with each other by means of a film hinge and can be coupled to You form a complete shell.

The right partial shell 2 in the representation is provided on the outer side with a labeling plate 5 that serves as the marking zone, which extends on both sides - in the direction of the line - beyond the partial shell 2, as It is shown in Figures 2 and 3. The left partial shell 3 in the representation is provided with a support body 6 which will be explained still in detail, which is elastically deformable.

The partial shell 2 presenting the labeling plate 2 is configured in the form of a prism on the inner side and in the area associated with the labeling plate 5, so that this configuration is formed by two inclined surfaces 10, 11 which are in an obtuse angle to each other.

As shown particularly clearly in Figure 1, the support body 6 configured in the form of a trapezoid in the cross section is provided with several constrictions 12 of the cross section, which are arranged on an alternate side. In this case, on the inner side two constrictions 12 of the cross section are arranged in the deflection zone of the arms and two other constrictions 12 of the cross section are arranged on the outer side in the central area in the two longest arms . Additionally, in the exemplary embodiment shown, additional constrictions 12 of the cross-section are provided in the joining areas in the partial shell 3. For compensation of the different diameters of the lines 13, the constrictions 12 of the cross section are arranged such that the support body 6 can be compressed, as shown in Figures 5-7, 11 and 17-19.

Figures 4 to 7 show that in the marking device 1 elongated elements can be inserted, in particular lines 13, with different diameters. These are centered in each case in the center by means of the inclined surfaces 10, 11 and also with the smallest diameter according to figure 4 a pressure force is still applied on the line 13.

Lines 13 according to figures 5, 6, 7 are incremented in ascending sequence. In this case, Figure 5 shows that the support body 6 is deformed along the constrictions 12 of the cross-section, so that the height is reduced in the same way in ascending sequence. In the embodiment according to figure 6, two deviation zones of the support body 6 are projected out of the partial shell 3. To this end, this partial shell is provided in accordance with Figures 12 to 14 with an opening 14. In the embodiment according to Figure 6, this area projecting in front of the outer surface of the partial shell 3 is even older

Figures 8 to 11 show the placement of the marking device 1 on a line 13.

According to Fig. 8, the marking device 1 extended towards the line 13 is placed first, so that the inclined surfaces 10, 11 are at a distance from the line 13. The marking device 1 is then adjusted with respect to the line 13 such that the inclined surfaces 10, 11 come into contact with each other. Next, in accordance with Figures 9 and 10, the partial shell 3 which presents the support body 6 in the direction of the line 13 is pivoted. Through the insertion of the retention hook 7 in the retention recess 8, it is fixed Then the dialing device 1 on the line. In this case, the support body 6 is deformed as a function of the diameter of the line 13. The retainer 9 then engages behind the outer surface, which delimits the retention recess.

Figures 12 to 14 show in particular that the partial shell 3 presenting the support body 6 is provided with an opening 14, which is not only located in the area of ​​the support body 6, but is also sized in such a way that deflection zones of the support body 6 according to figures 6 and 7 can pass.

Figures 15 to 19 show another embodiment of the marking device 1 according to the invention. The difference with respect to the embodiments according to Figures 1 to 14 is that the support body 6 extends in an arc. In particular, from figure 15 it follows that the central zone again has a constriction 12 of the cross section. Partial shells 2 and 3 have the same construction as the embodiments according to Figures 1 to 15.

Figures 16 to 19 show that as the diameter of the line 13 increases, the deformation of the support body 6 increases.

The invention is not limited to the embodiment shown. It is advantageous that the marking device formed by two partial shells 2, 3 is configured prismatically on the inner side in the area of ​​the marking plate 5 by means of two inclined surfaces 10, 11 that form an obtuse angle to each other, from

so that each diameter of a line 13 is aligned in the center, and so that the other partial shell 3 has an elastic support body 6, which deforms more strongly as the diameter of the line 13 increases.
