Hölzerner Wurfspeer.
Die Erfindung bezieht sich auf hölzerne Wurfspeere und hat den Zwtck durch Verwendung dner hohlen Metall-oder Drahtspiraleinlage einen Wurfspeer aus minderen Holzsorten herzustellen, der in bezug auf die Bauart (hohle Ausbildung) als auch in bezug auf die Festigkeit den sonst gebräuchlichen Speeren aus edlen Holzsorten entspricht.
In der Zeichnung ist eine Ausführungsform des neuartigen Speeres in einem Längsschnitt zur Darstellung gebracht.
Wie ersichtlich, besteht der Wurfspeer aus der der Spperform angepassten Heizrohre a, die in
EMI1.1
Diese Röhre b besteht aus Aluminium, einem sonstigen Leichtmetall oder einer enggevvickelten Drahtspirale. Diese Einlage ist bei weniger elastischen Holzsorten bis zur Spitze des Speeres durchgeführt. Bei vollelastischen Holzsorten ist die Länge dieser Röhre b den Holzsorten angepasst, derart, dass in jedem Falle ein voller Ausgleich der auftretenden Schwingungen als auch die Erzielung der erforderlichen Stabilität und eine dementsprechend hohe Flugweite des Speeres erzielt wird.
Derart aufgebaute Wurfspeere ermöglichten ausserdem durch die Verwendung minderer Holzsorten und der mit geringen Kosten herstellbaren Einlage, gegenüber den bisherigen aus edlen Hölzern bestehenden Wurfspeeren eine wesentliche Herabsetzung der Herstellungskosten.

Wooden throwing spear.
The invention relates to wooden javelins and has the purpose of using the hollow metal or wire spiral insert to produce a javelin from inferior types of wood, which in terms of construction (hollow design) as well as in terms of strength, the otherwise common spears made of noble types of wood corresponds.
In the drawing, an embodiment of the novel spear is shown in a longitudinal section.
As can be seen, the javelin consists of the heating pipes a, which are adapted to the shape of the body and are
EMI1.1
This tube b consists of aluminum, some other light metal or a tightly wound wire spiral. With less elastic types of wood, this inlay is carried out to the tip of the spear. In the case of fully elastic types of wood, the length of this tube b is adapted to the types of wood in such a way that in each case a full compensation of the vibrations that occur as well as the achievement of the required stability and a correspondingly high flight range of the spear is achieved.
Throwing spears constructed in this way also enabled a significant reduction in production costs compared to the previous javelins made of noble woods, thanks to the use of inferior types of wood and the insert that can be produced at low cost.
