Description
Kunststoffhülse zum Verbinden zweier Teile Die Erfindung bezieht sich auf eine Kunststoffhülse zum Verbinden zweier Teile. Bekannt sind Hülsen aus Holz oder Kunststoff in Form von VollhUlsen. Diese Hülsen sind, soweit sfe aus Kunststoff gefertigt sind, sehr materialaufwendig und kostspielig, so daß sie sich gegenüber den Hülsen aus Holz nicht durchsetzen können. Plastic sleeve for connecting two parts The invention relates on a plastic sleeve to connect two parts. Sleeves are known Wood or plastic in the form of full sleeves. As far as sfe is concerned, these sleeves are made of plastic are made, very material and expensive, so that they are opposite can not enforce the sleeves made of wood.
Aufgabe der Erfindung ist es daher, diese Verbindungshülsen so zu verbessern, daß erheblich an Material eingespart werden kann. The object of the invention is therefore to provide these connecting sleeves in such a way improve that a considerable amount of material can be saved.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Verbindungshülse hohl ist. Durch diese besondere Gestaltung wird außerordentlich viel Material eingespart, was sich nicht nur auf die Herstellungskosten, , sondern darUber hinaus auch auf das Gewicht gUnstig auswirkt. Auch wird dadurch die Knick- und Abscherfestigkeit der Hülse erhöht, da ja bekanntlich ein Hohlkörper, z.B. ein Rohr, eine größere Knick- und Abscherfestigkeit besitzt als ein Vollkörper, also eine Stange. This object is achieved according to the invention in that the connecting sleeve is hollow. This special design saves an enormous amount of material, which affects not only the manufacturing cost, but beyond that even has a beneficial effect on weight. This also increases the buckling and shear strength of the sleeve, since it is well known that a hollow body, e.g. a pipe, has a larger one It has buckling and shear strength as a solid body, i.e. a rod.
Diese Festigkeiten werden noch durch die Anbringung von längs verlaufenden Stegen im Inneren des Hohlraumes erhöht. These strengths are made even more by the addition of lengthways Raised webs inside the cavity.
Auch kann die Wandstärke der HUlse dünner bemessen werden, da ja die Stege einen Teil der Belastung der Hiilsenwandung aufnehmen.The wall thickness of the sleeve can also be made thinner, since the Bars absorb part of the load on the sleeve wall.
Zweckmäßig besitzt die Verbindungshülse an ihren Enden Fasen oder Einziehungen. Hierdurch wird gewährleistet, daß die nacheinander von der Maschine automatisch eingedrückten Hülsen sich störungsfrei in die Bohrungen einführen lassen. The connecting sleeve expediently has bevels or bevels at its ends Recoveries. This ensures that the one after the other from the machine automatically pressed-in sleeves can be inserted into the bores without any problems.
Nach einem weiteren Merkmal der Erfindung kann die HUlse an dem einen oder auch an beiden Enden geschlossen sein. According to a further feature of the invention, the sleeve on the one or closed at both ends.
Einige Ausführungsbeispiele der erfindungsgemäßen VerbindungshUlsen sind nachstehend anhand der Zeichnung noch etwas näher erläutert. In der Zeichnung zeigen in rein schematischer Weise: Fig. 1 einen senkrechten Schnitt durch eine erste lusführngsform der erfindungsgemäßen Verbindung shül s e Fig. 2 einen senkrechten Schnitt quer zur Längsachse der Hülse einer zweiten Ausführungsform Fig. 3 einen senkrechten Schnitt durch eine dritte Ausführungsform der erfindungsgemäßen Hülse Fig. 4 einen senkrechten Schnitt durch eine vierte Ausführungsform der erfindungsgeilißen Hülse Fig. 5 einen senkrechten Schnitt durch eine fUnfte AusfUhrungBform der erfindungsgemäßen Hülse. Some embodiments of the connecting sleeves according to the invention are explained in more detail below with reference to the drawing. In the drawing show in a purely schematic manner: FIG. 1 a vertical section through a first lusführngsform the connection according to the invention shül s e Fig. 2 is a vertical Section transverse to the longitudinal axis of the sleeve of a second embodiment Fig. 3 a vertical section through a third embodiment of the sleeve according to the invention Fig. 4 shows a vertical section through a fourth embodiment of the invention Sleeve Fig. 5 shows a vertical section through a fifth embodiment of the invention Sleeve.
Die Figur 1 der Zeichnung zeigt eine hohle Hülse zum Verbinden zweier Teile aus Kunststoff. Die Außenoberfläche kann dabei glatt sein oder zur Vergrößerung der haftenden OberflächE mit der Länge nach verlaufenden Rillen versehen sein. Die Oberfläche kann auch zur Erhöhung der Haftfestigkeit mit quer zur Längsachse verlaufenden Rillen oder mit Vertiefungen oder Erhöhungen, z.B. Widerhaken, versehen sein und dergleichen. Dabei besitzen die beiden Enden der Hülse Fasen 1 oder Einziehungen. Figure 1 of the drawing shows a hollow sleeve for connecting two Parts made of plastic. The outer surface can be smooth or for enlargement the adhesive surface must be provided with longitudinal grooves. the Surface can also be used to increase the adhesive strength with transverse to the longitudinal axis Grooves or with depressions or elevations, e.g. barbs, and like that. The two ends of the sleeve have chamfers 1 or recesses.
Die Figur 2 zeigt eine VerbindungshUlse im Schnitt mit Stegen 2 zur Versteifung. Die Anzahl dieser Stege 2 kann beliebig sein; sie richtet sich nach den Jeweils zulässigen Belastungen der Hülse. Figure 2 shows a connecting sleeve in section with webs 2 for Stiffening. The number of these webs 2 can be arbitrary; it is based on the respective permissible loads on the sleeve.
Die AusfUhrungsform nach Figur 3 unterscheidet sich von derjenigen nach Figur 1 lediglich dadurch, daß das eine Endf der Hülse geschlossen ist. The embodiment according to FIG. 3 differs from that according to Figure 1 only in that one end of the sleeve is closed.
Bei der Verwirklichungsform nach Figur 4 sind beide Hülsenenden geschlossen und mit einer Fase 1 versehen. In the embodiment according to FIG. 4, both sleeve ends are closed and provided with a bevel 1.
Es ist klar, daß die Stege 2 nicht nur bei diesen hohlen Hülsen, sondern auch bei anderen Hohlkörpern dieser Art, z.B. Rohren und dergleichen, vorteilhaft anwendbar sind. Dieser Erfindungsgedanke erstreckt sich hiernach keineswegs lediglich auf Hülsen als solche. It is clear that the webs 2 not only in these hollow sleeves, but also with other hollow bodies of this type, e.g. pipes and the like, advantageous are applicable. This inventive concept by no means merely extends hereafter on pods as such.
Nach einer weiteren Ausführungsform gemäß Figur 5 hat die Hülse etwa in der Mitte auf ihrer Außenfläche eine ringförmige Verstärkung 3 oder ringförmig angeordnete Erhöhungen und dergleichen als Arretierung, um zu gewährleisten, daß die Verbindungshulse in die miteinander zu verbindenden Teile gleic mäßig tief hineinragt. Aus fertigungstechnischen Grunde sind die Ubergänge der Stege 2 abgerundet. Die Stege 2 können jede beliebige Form und Querschnitt besitzen. According to a further embodiment according to FIG. 5, the sleeve has approximately in the middle on its outer surface an annular reinforcement 3 or annular arranged elevations and the like as a locking to ensure that the connecting sleeve protrudes equally deep into the parts to be connected. For manufacturing reasons, the transitions of the webs 2 are rounded. the Web 2 can have any shape and cross section.
