Definitions

  • the present invention relates to a device intended to be used for splitting logs or similar pieces of wood.
  • US-A-4,188,987 describes a device for splitting pieces of wood, presented in the form of a portable device comprising a threaded rotary cone oriented tip down driven by a motor and supporting a fixed corner whose lower edge meets perpendicularly the geometric axis of the spin and is located above its point and quite far from said axis.
  • this device it is the spin which, by penetrating deeply into the log alone, splits it, the corner taking over only to prevent rotation and to spread and then separate the two resulting pieces. It is obviously the spin which supports all the efforts and it is therefore necessary a powerful motorization to drive it and, consequently, it risks the rupture.
  • This apparatus of the above-mentioned type is characterized in that the corner which it comprises is provided with an oblique cutting edge forming, with the geometric axis of the threaded cone, an acute angle which widens downwards and whose one of the ends is located in the immediate vicinity of the threaded surface of the cone, while the other end extends downwards further than the lower point of said cone.
  • the cutting edge of the corner penetrates very early into the side of the log against which it rests, at the same time as the spin which attacks the log overhead and tends to press it against the corner to split it.
  • the fixed base comprises, under its lower part, a fixed push shoe placed next to the periphery of the rotary cone, in the zone where the tangential speed of the latter is oriented in the direction which moves away from the fixed corner.
  • the fixed push shoe is located on its left, when for the user looking at the device from top to bottom, the corner is located towards the artery.
  • the device illustrated in the drawings comprises a base 1, surmounted by a cover 2, provided with a handling handle 3. At the front, this handle is preferably equipped with a push button 4, actuating in the known manner, an electric switch not shown.
  • an electric geared motor 5 which, by means of an endless screw 6, and a toothed ring 7, drives in rotation around its vertical geometric axis 8, a cone of revolution 9, provided on its periphery, with a large module thread.
  • the tip 10 of the rotating cone 9 is directed downwards.
  • a metal corner 11 provided at its lower part with a tapered rectilinear edge 12, oriented from bottom to top, towards the cone 9.
  • the edge 12 ends in a heel 19, preferably rounded.
  • a spout 14 located in the immediate vicinity of the periphery of the cone 9, for example at the lower third of its length.
  • the lower heel 13 of the edge 12 of the corner 11 is located at a level 15, placed below the tip 10 of the cone 9.
  • the corner 11 has approximately the general shape of a tetrahedron whose rear face 15 has the shape of a curvilinear triangle which, at its upper part, is more flared than the rotating cone 9 , while at its lower part, its tapered shape corresponds to an angle at the top less than that of the tip 10 of the rotary cone 9.
  • FIG. 10 There is shown in Figures 10 and 11, a variant concerning the profile of the fixed corner 11 and its blade.
  • the front spout 14 of the oblique edge 12 is replaced by an angle 26 surmounted by a straight cutting edge 27, oriented parallel to the axis 8 of the rotary cone 9.
  • the edge 27 is connected on another rectilinear edge 28 which advances as close to the cone 9 along one, direction substantially perpendicular to the axis: 9.
  • the fixed corner 11 has a blade, comprising, as before, the oblique upper edge 12, but this extends downwards, through the cutting edge 27 slightly inclined towards the back and down, ending in a cutting edge 29 with a convex profile towards the front.
  • This last variant facilitates the splitting of a log of great length (for example more than one meter).

1. Tragbare Vorrichtung zum Spalten von Holzstämmen, Holzblöcken u.ä., bestehend aus einem drehbaren Konus mit Gewinde (9), dessen Spitze nach unten zeigt und der von einer elektrischen Motor-Getriebe-Kombination (5) angetrieben wird, sowie aus einem feststehenden Keil (11), dessen Oberteil mit der Fußplatte (1) eines Gehäuses (2) für die Motor-Getriebe-Kombination fest verbunden ist, dadurch gekennzeichnet, daß der feststehende Keil (11) eine schräge Kante (12) besitzt, die mit der geometrischen Achse (8) des Gewindekonus (9) einen spitzen, sich nach unten erweiternden Winkel bildet und deren eines Ende (14) sich unmittelbar neben der Gewindefläche des Konus (9) befindet, während ihr anderes Ende (13) weiter nach unten reicht als die Spitze des besagten Konus (9).
2. Vorrichtung entsprechend Patentanspruch 1, dadurch gekennzeichnet, daß die untere Schrägkante (12) des feststehenden Keils (11) an eine geradlinige Kante (27) anschließt, die senkrecht über ihr parallel zur Achse (8) des Konus (9) verläuft und an deren oberem Ende wiederum eine geradlinige Kante (28) anschließt, die eindeutig senkrecht zur Achse (8) des Konus (9) verläuft und in dessen Nähe endet.
3. Vorrichtung entsprechend Patentanspruch 1, dadurch gekennzeichnet, daß der feststehende Keil (11) eine scharfe Schneide besitzt, deren obere Schrägkante (12) nach unten durch eine geradlinige, leicht nach hinten unten geneigte Schnittkante (27) fortgesetzt wird und anschließend in einer Schnittkante (29) mit nach vorn gerichtetem konvexem Profil endet.
4. Vorrichtung entsprechend Patentanspruch 1, dadurch gekennzeichnet, daß die feststehende Fußplatte (1) an ihrer Unterseite einen feststehenden Schubklotz (17) besitzt, der in der Peripherie des Drehkonus (9) angebracht ist, und zwar in dem Bereich, wo dessen Tangentialkraft in der Richtung verläuft, die sich von dem feststehenden Keil (11) entfernt, dergestalt daß sich der feste Schubklotz (17), von oben gesehen, links von dem Gewindekonus (9) befindet, wenn dieser sich "nach rechts" dreht und der feststehende Keil hinten liegt.
