Abstract

In the case of such a snap holder, a clip 8 can be fixed in a lower part 3 and the wire 1 can be fixed by means of a snap device 10. In this case, it is desirable for a snap holder (which holds the wire such that it is protected against being pressed out transversely with respect to the length of the wire) to hold the wire such that it is optionally axially displaceable or axially non-displaceable in each case when the clip is fully inserted and fixed. This is achieved in that the clip 8 and lower part 3 are held against one another by means of a screw connection 13, it being possible to adjust the distance between the recesses 7 in the lower part and the opposing bearing edges 11 of the clip to two settings, and the limbs 9 of the clip 8 being arranged rotated through 90 DEG with respect to the lower part, and having claws 10 which form the opposing bearing edges 11. The wire 1 is held displaceably or non-displaceably between the claws and the recesses, depending on the distance setting. <IMAGE>

Description

Diese Verstellbarkeit ist mittels der Schraubverbindung verwirklicht. Um das Durchdrücken des Drahtes bei voll eingeschobenem Bügel zu ermöglichen, ist der Bügel um 900 versetzt vom Unterteil hinterfaßt angeordnet und mit den federnden Krallen ausgerüstet. Die Federung der Schnappeinrichtung ist durch die Krallen gegeben, und die Schenkel des Bügels sind massiv und können bereits vor dem Einschnappen des Drahtes voll eingebaut werden. Die Montage des Schnapphalters samt Einbringen des Drahtes ist vereinfacht, wobei sich der Schnapphalter wegen der Schraubverbindung winkelmäßig verdreht anordnen läßt.This adjustability is achieved by means of the screw connection. To push the wire through at full with the inserted bracket closed enable, the bracket is arranged behind and offset by 900 from the lower part equipped with the springy claws. The suspension of the snap device is through given the claws, and the legs of the temple are massive and can already fully installed before the wire snaps into place. The assembly of the snap holder including the introduction of the wire is simplified, with the snap holder because of the screw connection can be arranged rotated at an angle.

Besonders zweckmäßig und vorteilhaft ist es, wenn der Bügel an den beiden Schenkeln des Unterteiles anliegt und die Krallen jeweils nach nur einer spitzwinkeligen Abbiegung relativ zu den Bügelschenkeln schräg zurück und aufeinanderzu verlaufen. Dieser samt den Krallen relativ schmale Bügel ergibt Krallen, die genügend Federkraft für die Schnappwirkung haben, einfach herzustellen sind und ein Herausdrücken des Drahtes quer zur Länge mit Sicherheit verhindern. It is particularly useful and advantageous if the bracket to the both legs of the lower part rests and the claws each after only one acute-angled bend relative to the bow legs obliquely back and towards each other get lost. This, together with the claws, relatively narrow bracket results in claws that are sufficient Have spring force for the snap action, are easy to manufacture and push out of the wire across the length with certainty.

Besonders zweckmäßig und vorteilhaft ist es auch, wenn das Unterteil ein rundum geschlossenes Gehäuse ist. Da das Unterteil keine federnden Eigenschaften und Einrichtungen aufweist, kann es als geschlossenes Gehäuse gegossen werden, wobei es nicht nur aus Metall, sondern auch aus einem harten Kunststoff, z. B. PVC, bestehen kann. It is also particularly useful and advantageous if the lower part is a completely closed housing. Because the lower part has no resilient properties and having facilities, it can be cast as a closed housing, wherein it is not only made of metal, but also of a hard plastic, e.g. B. PVC exist can.

Es ist denkbar, als Schraubverbindung eine Mutter und eine Schraube mit Kopf vorzusehen. Besonders zweckmäßig und vorteilhaft ist es aber unter Umständen auch, wenn der Durchbruch des Bügelbodens mit einem Schraubgewinde versehen ist. Der Schnapphalter wird auf einen feststehenden Bolzen mit Gegengewinde aufgeschraubt. It is conceivable to use a nut and a screw as the screw connection to be provided with head. Under certain circumstances, however, it is particularly expedient and advantageous even if the opening of the bracket base is provided with a screw thread. The snap holder is screwed onto a fixed bolt with a mating thread.

Besonders zweckmäßig und vorteilhaft ist es, wenn zwischen Bügelboden und Unterteil-Boden eine Beilegscheibe angeordnet ist. Diese Art, die Abstands-Verstellbarkeit zu verwirklichen, ist in der Herstellung recht einfach, da es nur einer zusätzlichen Beilegscheibe aus hartem Werkstoff bedarf. It is particularly useful and advantageous if between the bracket base and a washer is arranged in the lower part bottom. This kind, the distance adjustability to realize is quite simple to manufacture, since there is only one additional Washer made of hard material is required.

Besonders zweckmäßig und vorteilhaft ist es sodann, wenn die Unterseite des Bügelbodens und die Oberseite des Unterteil-Bodens aneinander angepaßt abgestuft sind. Diese Art, die Abstands-Verstellbarkeit zu verwirklichen, vermeidet ein zusätzliches Teil. Bei der Anordnung, bei der der vorspringende Bereich des Bügelbodens an den zurückspringenden Bereich des Unterteil-Bodens angelegt ist, ist geringer Abstand gegeben; bei der Anordnung, bei der der vorspringende Bereich des Bügelbodens an den vorspringenden Bereich des Unterteil-Bodens angelegt ist, ist größerer Abstand gegeben. It is then particularly expedient and advantageous if the underside of the bracket base and the top of the lower part base adapted to one another stepped are. This way of realizing the distance adjustability avoids an additional one Part. In the arrangement in which the protruding area of the bracket base to the the receding area of the lower part bottom is created, there is a small gap given; in the arrangement in which the protruding area of the bracket base is on the protruding area of the lower part bottom is created, is greater distance given.

Besonders zweckmäßig und vorteilhaft ist es weiterhin, wenn das Unterteil als im Querschnitt rechteckiges Gehäuse ausgebildet ist und an den um 900 gegeneinander versetzten Paaren von Seiten Ausnehmungen verschiedener Tiefe aufweist. Diese Art, die Abstands-Verstellbarkeit zu verwirklichen, vermeidet ein zusätzliches Teil sowie unebenen Bügel- und Unterteil-Boden. It is also particularly useful and advantageous if the lower part is designed as a housing with a rectangular cross section and at the 900 against each other has staggered pairs of sides recesses of different depth. This kind, Realizing the distance adjustability avoids an additional part as well uneven bracket and base bottom.

Die Abstands-Verstellbarkeit läßt es allgemein nicht nur zu, einen Draht einmal verschiebbar und zum anderen unverschiebbar festzulegen, sondern läßt es auch zu, zwei Drähte verschiedener Dicke axial unverschiebbar festzulegen. Dies ist von Bedeutung, weil Blitzableiterdrähte aus Aluminium und Kupfer in der Regel verschiedene Durchmesser aufweisen. Diese Verwendungsmöglichkeit ist besonders bei dem gehäuseförmigen Unterteil mit zwei Paaren verschiedener Ausnehmungen sinnvoll, wenn diese dem Drahtdurchmesser genau angepaßt sind. The distance adjustability generally allows not only one Wire can be fixed on the one hand and immovable on the other, but leaves it is also possible to fix two wires of different thicknesses in an axially immovable manner. this is important because lightning rods are usually made of aluminum and copper have different diameters. This usage option is especially useful for the housing-shaped lower part with two pairs of different recesses makes sense, if these are exactly matched to the wire diameter.

Besonders zweckmäßig und vorteilhaft ist es noch, wenn die Ausnehmung teilkreisförmig mit einem Radius, der dem Radius des Drahtes angepaßt ist, geformt ist. It is particularly useful and advantageous if the recess Partly circular shaped with a radius which is adapted to the radius of the wire is.

Dies verbessert die wackelarme Lage eines verschiebbaren Drahtes und die Festlegung eines unverschiebbaren Drahtes.This improves the wobbly position of a sliding wire and the definition of an immovable wire.

Besonders zweckmäßig und vorteilhaft ist es, wenn an der Bodenunterseite des Unterteiles ein den Unterteil-Boden rundum seitlich überragender, von der Schraubverbindung durchdrungener Fuß vorgesehen ist. Dieser aufgrund der Schraubverbindung ermöglichte Fuß vergrößert den Abstand des Schnapphalters vom Tragteil und deckt der Schraubverbindung wegen vorgesehene Bohrlöcher im Tragteil, das z. B. Mauerwerk ist, ab. It is particularly useful and advantageous if on the underside of the floor of the lower part one that protrudes laterally all around the lower part bottom, from the screw connection penetrated foot is provided. This made possible due to the screw connection The foot increases the distance between the snap-on holder and the supporting part and covers the screw connection because of provided holes in the supporting part, the z. B. Masonry is from.

Individual embodiments of the invention are shown in the drawing and shows in FIG. 1 is a perspective view of a snap holder for a Lightning conductor wire, FIG. 2 shows a section of the line holder according to FIG. 1, FIG. 3 shows the section according to FIG. 2 with an inserted washer, FIG. 4 a section a further embodiment of a snap-fit holder for a lightning conductor wire and FIG. 5 shows a section along line V-V in FIG. 4.

Die Schnapphalter gemäß Zeichnung dienen dazu, einen im Querschnitt kreisrunden Draht 1 an einem Tragteil festzulegen, das z. B. ein gewinkelter Tragstreifen ist. Die Schnapphalter umfassen jeweils ein im Querschnitt rechteckiges gehäuseartig ausgebildetes Unterteil 3, das einen Boden 4 mit zwei den Draht aufnehmenden Schenkeln 5 und zwei weiteren Wänden 6 bildet. The snap holders according to the drawing are used to create a cross-section set circular wire 1 on a support part that z. B. an angled support strip is. The snap holders each have a housing-like shape with a rectangular cross section formed lower part 3, which has a bottom 4 with two legs receiving the wire 5 and two other walls 6 forms.

Am oberen Rand der Schenkel 5 bzw. Wände 6 sind teilkreisförmige Ausnehmungen 7 vorgesehen, in die der Draht 1 einlegbar ist.On the upper edge of the legs 5 or walls 6 are part-circular recesses 7 is provided, into which the wire 1 can be inserted.

In das Unterteil 3 ist ein U-förmiger, rechtwinkelig gebogener Bügel 8 aus Federblech eingeschoben, dessen Schenkel 9 nach oben aus dem gehäuseartigen Unterteil herausragen und an den herausragenden Enden mit spitzwinkelig abgebogenen Krallen 10 versehen sind, die ebenso breit wie die Schenkel sind. Die Krallen 10 sind gleich lang, im wesentlichen gerade, weisen schräg abwärts aufeinander zu und bilden an den freien Enden Widerlagerkanten 11, die sich dicht beim Draht 1 befinden oder gegen diesen drücken. Der Abstand der freien Enden bzw. der Widerlagerkanten 11 voneinander ist beachtlich kleiner als der Durchmesser des Drahtes 1, so daß die Krallen 10 zurückfedern müssen, wenn der Draht durchgedrückt wird. In the lower part 3 is a U-shaped, bent bracket at right angles 8 inserted from spring steel sheet, the legs 9 of the housing-like upwards The lower part protrudes and the protruding ends are bent at an acute angle Claws 10 are provided, which are as wide as the legs. The claws 10 are of equal length, essentially straight, point diagonally downwards towards each other and form abutment edges 11 at the free ends, which are located close to the wire 1 or press against it. The distance between the free ends or the abutment edges 11 from each other is considerably smaller than the diameter of the wire 1, so that the claws 10 must spring back when the wire is pushed through.

Wie z. B. Fig. 2 erkennen läßt, sind der Boden 4 des Unterteiles 1 und der Boden 12 des Bügels 8 von einer Schraubverbindung 13 mittig durchdrungen, fest gegeneinander gehalten und an dem Tragteil 2 befestigt. Gemäß Fig. 2 liegen die beiden Böden 4, 12 ganzflächig aneinander an und sind plan ausgebildet. Gemäß F i g. 3 ist eine Beilegscheibe 14 zwischengelegt, um einen in die Ausnehmung genau passenden Draht verschiebbar anzubringen. Gemäß Fig. 4 sind die beiden Böden 4, 12 entlang einer Mittellinie mit einer Abstufung 15 versehen. Das Unterteil 3 ist am Boden mit einem Fuß 16 versehen. Such as B. Fig. 2 shows, the bottom 4 of the lower part 1 and the bottom 12 of the bracket 8 penetrated in the middle by a screw connection 13, held firmly against each other and attached to the support part 2. According to Fig. 2 lie the two floors 4, 12 adjoin one another over the entire surface and are planar. According to F i g. 3, a washer 14 is interposed to precisely fit one into the recess appropriate wire to be slidably attached. According to Fig. 4, the two floors 4, 12 provided with a gradation 15 along a center line. The lower part 3 is provided with a foot 16 at the bottom.
