Die Mittelpunkte der Radien liegen außerhalb des Trichters. Im Ausführungsbeispiel gemäß Fig. 4 ist eine hyperboloidische Trichterwandung 7 gezeigt, deren Wölbungsradien zur offenliegenden Trichteröffnung 23 stetig verringert sind. Es kann auch vorteilhaft sein, die Trichterwandung 7 mit einem einzigen Wölbungsradius oder zwei oder mehr abschnittsweise aneinandergesetzten Radien zu gestalten. Die Tangente 22 der Wandwölbung kann am Ende, d. h. dem umlaufenden Rand 19 der Trichteröffnung 23 in einem Winkel α von bis zu 90° oder ggf. noch stumpfwinkliger zur Längsmittelachse 21 des Führungskanals 5 liegen. Es sind dabei im Einsatz der Seilwinde extreme Schrägzuglagen des Lasttrums 4 relativ zur Ausrichtung des Seilfensters entsprechend dem Winkel α zwischen Wölbungstangente 22 und Längsmittelachse 21 möglich, wobei der Lasttrum 4 mit geringer Reibung durch das Seilfenster gezogen wird. Bei den üblichen Ablenkwinkeln von 10° oder weniger wird das Seil beim Durchgleiten des Seilfensters erheblich geringer verschlissen als bisher. Der äußere Rand der Stirnseite 12 des Einsatzbautelis ist zweckmäßig abgerundet ausgebildet. Die zweiteilige Führungshülse 2 besteht im gezeigten Ausführungsbeispiel aus Kunststoff, vorzugsweise Polyamid. Es können jedoch auch andere Werkstoffe wie Metall oder Holz oder auch anderes zweckmäßig sein.The convex funnel wall 7 has different radii of curvature r1, r2, with the radius r2 closer to the funnel opening 23 lying wall section less is. The centers of the radii are outside the Funnel. 4 is a hyperboloid Funnel wall 7 shown, the curvature radii steadily reduced to the exposed funnel opening 23 are. The funnel wall can also be advantageous 7 with a single radius of curvature or two or to design more radii placed in sections. The tangent 22 of the wall curvature can at the end, i.e. H. the peripheral edge 19 of the funnel opening 23 in one Angle α of up to 90 ° or possibly even more obtuse Longitudinal central axis 21 of the guide channel 5 lie. There are extreme diagonal pull positions when using the cable winch Lasttrums 4 relative to the orientation of the rope window accordingly the angle α between the tangent 22 and Longitudinal central axis 21 possible, the load strand 4 with less Friction is pulled through the rope window. Both The rope becomes the usual deflection angle of 10 ° or less significantly less wear when sliding through the rope window as before. The outer edge of the end face 12 of the Einsatzbautelis is appropriately rounded. The two-part guide sleeve 2 is in the embodiment shown made of plastic, preferably polyamide. It can also use other materials such as metal or wood or other appropriate.

Die Hülsenhälften 3, 3' sind besonders in hohen Stückzahlen kostengünstig als Spritzgußteil herstellbar, insbesondere in der gezeigten identischen Ausführungsform mit paarweise angeordneten Bohrungen 25 zur Aufnahme der Verbindungsstifte. Dabei können auf beiden Seiten der Längsmittelachse 21 der Hülsenhälften jeweils mehrere Paare Bohrungen vorgesehen sein. Eine Herstellung der Hülsenhälften 3, 3' aus Vollmaterial, wie etwa bei Metall- oder Holzeinsätzen, kann auch in der Kunststoffausführung des Einsatzbauteils vorteilhaft sein, beispielsweise aus Fertigkeitsgründen.The sleeve halves 3, 3 'are particularly large quantities inexpensive to produce as an injection molded part, in particular in the shown identical embodiment with pairs arranged holes 25 for receiving the connecting pins. It can on both sides of the longitudinal central axis 21 of the sleeve halves each provided several pairs of holes his. A production of the sleeve halves 3, 3 ' Solid material, such as metal or wooden inserts, can also advantageous in the plastic version of the insert component be, for example, for skill reasons.

Das erfindungsgemäße Seilfenster besteht aus sehr wenigen, leichten Einzelteilen. Das Gesamtgewicht des Seilfensters ist daher sehr gering, was insbesondere bei Verwendung des Seilfensters bei transportablen Seilwinden, beispielsweise in Fahrzeugen vorteilhaft ist. Auch die Montage des Seilfensters ist mit wenigen und dabei leichten Einfügeteilen vereinfacht. Der Austritt des Führungskanals 5 auf der windenzugewandten Stirnseite 13 des Einsatzbauteils ist mit einer Fase 20 versehen und ist so vor erhöhtem Abrieb durch das durchlaufende Drahtseil geschützt.The rope window according to the invention consists of very few, lightweight individual parts. The total weight of the rope window is therefore very low, which is particularly the case when using the Rope window in portable winches, for example is advantageous in vehicles. Also the assembly of the rope window is with few and at the same time light insert parts simplified. The exit of the guide channel 5 facing the winch Front side 13 of the insert component is with a chamfer 20 and is thus before increased abrasion the continuous wire rope is protected.
